EdUHK’s far-reaching project for education in Cambodia

The Education University of Hong Kong (EdUHK) has begun its partnership with Cambodian universities and the Ministry of Education, Youth and Sports in a World Bank project to build the capacity of higher education teachers for inclusive and quality learning and teaching in the Southeast Asian country.

Developing pedagogical competences

To achieve this, EdUHK and the Royal University of Phnom Penh (RUPP) have co-established the Centre of Excellence in Higher Education Teachingand Learning and Innovations, and teachers from five Cambodian universities have been awarded places on EdUHK’s Doctor of Education (EdD) programme, through scholarships funded by the World Bank’s Higher Education Improvement Project.

“Like many others around the world, university teachers in Cambodia have deep expertise in their field but may not get the opportunity to develop their pedagogical competencies,” explains principal investigator, Professor Lim Cher Ping, Chair Professor of Learning Technologies and Innovation at EdUHK. He first met Cambodian university rectors and the Director-General for Education (DGE) at a workshop in Siem Reap, 10 years previously. In 2018, the DGE contacted him about sharing promising practices. “The universities wanted their teachers to learn how to conduct more interactive classes, with valid, reliable and comprehensive assessment,” says Professor Lim.

“We have recently created a faculty of education, and we particularly wanted to work with EdUHK because we have the same vision for learning and teaching,” says Dr Sok Soth, Dean of Faculty of Education at RUPP. Another reason he gave was the fact that academia in Hong Kong has been exposed to both eastern and western approaches. “If we tried to directly implement American or European epistemology onto a Cambodian context, it wouldn’t necessarily fit. EdUHK’s hybrid model is a much better match,” he adds.

Setting criteria

While EdUHK and RUPP had already agreed in principle to the project’s overall goals, the World Bank played a key role by setting the objectives, drawing out a partnership agreement and providing the finance. “It’s an important and complicated project. There was a need in the Cambodian higher education sector for this project to start quickly and it involves six universities in total. When the co-partners designed the project, we had to agree on the criteria to measure quality standards, work out how to measure outcome as well as output, and establish a team of knowledgeable external professors to assess impact,” says Dr No Fata, Education Specialist at the World Bank.

The project is far-reaching, in that the ‘master teachers’ on the Graduate Certificate of Higher Education Teaching and Learning programme will drive and facilitate professional development for teachers within their own faculty and university, and eventually cascade the methods to all universities in Cambodia. “This is key. Until now, there has been no standardised system. University teachers give classes according to their own educational influences, and university students only receive a ‘pass’ or ‘fail’ grade,” explains Dr No. He adds that the project’s success will be measured on quality and on-time delivery. It also depends on how successfully the master teachers will be at passing on pedagogical methods within their universities, and making changes to how students learn and are assessed.

Passing on knowledge

Some of the master teachers on the World Bank funded scholarship spent a semester at EdUHK earlier this year, and it proved to be a valuable experience. One of them, Chey Sotharoth, describes her experience on the EdD programme as hard work, with a lot of different dynamics involved. “We have had to adjust to a different culture of learning and, because of the pandemic, we weren’t able to travel to Hong Kong right away. But the supervisors at EdUHK are very supportive. There was a good mix of EdD students on campus. They were from a variety of places. Some had started the programme before me, so they gave me a lot of good advice. I learnt a lot about other cultures, as well as the tenacity and consistency required to study in a different environment,” she says.

While the project is due to run until June 2024, the aim is for it to have a much longer legacy. “Once they’ve completed the EdD programme, the master teachers will not only pass on their knowledge to teachers in the partner universities, but eventually in the 100 or so other public and private higher education institutions across Cambodia,” says Professor Lim. This flow of education can have a widespread positive impact on the country. “Sharing best practices and vision helps close the gaps in learning and teaching, and research. If education is improved, so is society and the way we all live our personal and professional lives,” says Dr Sok.

Balancing old and new preschool methods

Two EdUHK early childhood education (ECE) experts visited Cambodia in July as part of the ‘Cambodia Early Childhood Education Project’ (CECEP).

Under the umbrella of the World Bank project in which EdUHK is a partner, Professor Kerry Lee and Dr Alfredo Bautista, met with ECE leaders at the Royal University of Phnom Penh (RUPP) and the Cambodian Ministry of Education, Youth and Sports. The objectives were to discuss current issues related to ECE in Cambodia and various policy initiatives, as well as speaking with 25 senior teachers and ministry officials.

The visit gave Professor Lee and Dr Bautista a first-hand view of the ECE system in Cambodia. “We saw schools in Phnom Penh, Siem Reap and Battambang. They are well-resourced, but Cambodia doesn’t have many ECE specialists. So, we aim to train experienced primary and secondary educators, who can then teach and provide care to early years children,” says Professor Lee. The experts also visited different types of preschools and teacher education centres around the country, to better understand the local educational context and conditions. They saw schools and government working closely together, and that traditional single-subject teaching methods were still being used, which was something parents generally wanted. “We’ll have to balance those expectations with introducing educators and government officials to the modern integrated approach,” says Dr Bautista.

The project will continue until the end of 2023, and comprises three legs: training the trainer, conducting relevant research, and transferring knowledge through various activities. “In research you don’t always see the final impact. But in this project, it’s clear,” says Dr Bautista. Professor Lee concurs. “We feel we can make a real difference in ECE quality in Cambodia, and hopefully in other parts of the world too someday,” he adds.

Exploring differences in elite mobility during the Meiji Restoration

With a focus on the Meiji Restoration, researchers delve into the connections between political regime changes and social mobility.

Japan’s regime change in the 19th century from feudal to modern rule offers a classic example of elite mobility. In this regard, a new study of the Meiji Restoration by researchers from Japan provides novel insights on elite mobility during this transition. It tells us how this change allowed commoners to join the elite ranks. However, while the political changes facilitated social mobility, the extent of upward mobility differed at various stages of the change.

Social mobility refers to the movement of individuals from one socio-economic strata to another, followed by a change in their social status. In today’s world, social mobility is largely driven by personal motivation, education, skills and migration. But an analysis of historical data tells us that social mobility is primarily caused by changes in political rule. Political upheavals that caused the downfall of established regimes were followed by massive changes in the composition of elite mobility.

A new study by Junior Associate Professor Tomoko Matsumoto of the Tokyo University of Science and Professor Tetsuji Okazaki from the University of Tokyo provides new evidence on the correlation between elite mobility at various stages of the Meiji Restoration. The results of their study were published online in the British Journal of Sociology on 31st January, 2023.

Under the Tokugawa regime, Japan had a rigid class structure. The Shogun, Daimyos (feudal lords), and Samurai (noble class) constituted the upper class that ruled Japan. They possessed political privileges and were prohibited from interacting with the commoners (peasants, craftspeople, merchants). This restricted their social mobility as they were not allowed to change occupations, travel, or marry into a different class. In 1868, the Tokugawa Shogunate was defeated in a civil war and a new political regime came to power. This event marks the Meiji Restoration, that culminated in the formation of the ‘Imperial Diet’, which later became the highest framework of state power in Japan, called the National Diet.

“If we look back in history, we find that the Meiji Restoration was the first time that people were able to choose their future regardless of the environment in which they were born. During this historical period of transition, when equality of all natives and freedom of choice of occupation were recognized, how much social mobility actually occurred? This study was initiated in the hope of adding new insights during this period of transition,” say the researchers, explaining the rationale behind their study.

The study used statistical tools like hypothesis testing and data sampling to test the Meiji Restoration. “The Meiji Restoration has three advantageous aspects for our study besides data availability. Firstly, before the regime change, social mobility was extremely low. Secondly, the Meiji Restoration reformed the educational system drastically, and lastly, the regime change produced a new system of elite hierarchy,” explain the researchers about why they chose to focus on this period in history. The researchers divided the collected data into two cohorts to analyze the pre and post stages in regime change, and their varying effects on social mobility.

Regime changes lay the groundwork for non-elites to elevate themselves to the elite class, regardless of their social origin. During the various stages of a successful regime change, the new elites are not necessarily opposed to the old elites. The change is a gradual process which starts with a hostile relationship between the old and incumbent elites, but slowly evolves into a compromising one, after the political transfer of power is done. The researchers found that with the initial overthrowing of the old regime, the commoners had the biggest opportunity to join the elite classes. Meritocracy played a huge role at this stage. However, after the consolidation of the new regime, the opportunities for elite mobility gradually declined, as a stable structure, based on elite compromise, was created.

The results supported the hypotheses that social mobility usually occurred before the consolidation of a new political power. At that time, the commoners had the greatest chance to join the elite group and attain a high rank within the group. Meritocracy, based on education, also plays a vital role. After the new regime fortifies its position, the chances for merit-based elite mobility diminishes. This stage also signaled a decline in educational meritocracy.

“How can we realize a society where people can have the future they want if they make an effort, regardless of the environment in which they are born?” ponders Dr. Matsumoto. She hopes that with the findings of their study, this issue will be discussed objectively, looking back on short-term as well as long-term historical data.

Today, when we are aspiring for a society based on meritocracy and not on nepotism, these findings continue to enlighten us

Australian Crawl

“We had all said 2020 was going to be our best year yet. We didn’t see that coming, did we?” jokes Janine Bowmaker, President of Study Cairns, a study consortium set up to promote international education in the northern Queensland city.

“We had just created a new strategy and were exceptionally excited about the markets that we were moving into. “Numbers were definitely on the [upward] trajectory.”

In six years of covering Australian international education, firstly in 2015’s “Australia’s new wave” (The PIE Review #7) and again with “Australia’s rip tides” (The PIE Review #19) in 2018, the country’s sector moved from navigating troubled waters, to buoyant optimism, to nuanced readjustments, all while riding a swell of unprecedented growth in both value and student numbers, backed by the then newly created National Strategy for International Education 2025.

By the end of 2019, the country had once again broken its own records for the fifth consecutive year, reaching almost 760,000 international students. The pandemic put a stop to that growth and pivoted the focus of strategic planning from value adding readjustments to recovery and rebuilding across the board.

Now, a decade after its low point, Australia’s international education finds itself again swimming against the tide. 

It’s coming round again? 

Within some leadership circles, it’s become accepted, albeit begrudgingly, that a country’s international education sector operates within a roughly ten-year cycle as governments rejig national priorities. 

This policy “pendulum”, which opens and restricts international education, is seen as a consistent part of education and immigration strategy to address areas such as unintended loopholes, funding concerns, or skills shortages. 

The aim, according to those who lobby for policy change, is to ensure the pendulum never swings too far in one direction. In the late 2000s and early 2010s, however, it did just that, when Australia tightened study visa conditions in response to exploitation of migration links to vocational education, strangling the flow of students. 

Helped along by concurrent safety concerns and a historically strong Australian dollar, international student numbers plummeted 20 percent overall between 2009- 2012, according to figures from those losses took the better part of half a decade.

2020 and 2021 are different. 

“All the reasons that make Australia a fantastic place to study are exactly the same,” says Catriona Jackson, Chief Executive of higher education peak body Universities Australia. 

“We just happen to be in a situation at the moment in which people physically can’t get into the country.” 

After half a decade of growth, the closure of Australia’s international borders in March 2020 caused total numbers to dip, losing nine percent to end the year with 686,000 international students. 

Half year figures for 2021 from the Department of Education, Skills and Employment (DESE), meanwhile, provide a much starker picture of the ongoing impact of COVID-19 and border closures. 

Between the year to June period in 2020 and 2021, international student numbers dropped 17 percent; from 637,000 to 530,000. 

Enrolment figures, which are higher as many students undertake additional courses in a year such as a language or academic bridging programme prior to tertiary study, show a similar drop and highlight which sectors are most affected. 

Of the 127,00 fewer enrolments, 45,000 were in higher education. The worst affected, English language providers, shrank by 52,000. 

The losses so far this year have wiped out almost four years of growth and brought numbers back to just above 2017 levels. 

Funding and research 

Jackson says the drop in international students contributed to the universities sector losing AU$1.8 billion (US$1.3 billion) in 2020. 

“We predict a further two billion (US$1.5 billion) will be lost this year again because international students who really want to come to Australia just can’t get here,” she says. 

“[These] are numbers that no sector can absorb without some damage.” 

Jackson tells QS-GEN, universities and other education providers quickly understood the potential consequences of COVID-19 and worked to limit their losses by reducing spending where they could, but adds it’s not a sustainable practice. 

“The complexity for us as a sector is: you can only really do that once,” she warns. 

“You can’t stop essential expenditure for too long.” 

The revenue shortfalls compound ongoing issues around research funding. For many years, Australian universities used international student revenue to cross-subsidise research funding gaps, as well as teaching and operational costs. A funding freeze on domestic places in 2017, had already exacerbated the issue. 

To combat losses, the Australian government provided an additional $1 billion in research money in October 2020, but that only serves to soften the blow, says Jackson, noting actual losses prior to the funding injection were $2.8 billion.

“It was very useful; it saved research capacity and it saved jobs,” she says. 

“But it was a sustainability measure, it wasn’t a change the formula or change the regime measure. We’re still in considerable difficulty.” 

Jobs and growth 

At other levels of education, the economic consequences of COVID-19 have been just as swift. 

After 2016’s watershed Value of international education to Australia report, commissioned by the federal government and compiled by Deloitte Access Economics, Australia developed a sophisticated model to measure the economic impact of the sector. 

Factoring in previously ignored revenue, such as tourism by visiting family and friends, the report prompted changes by the Australian Bureau of Statistics (ABS). With additional revenue sources taken into consideration, the sector was valued beyond $40 billion in 2019. 

This value cannot be overstated for the country. International education, at the time, was Australia’s fourth largest export, and the single largest services export overall, far surpassing tourism. 

Meanwhile, figures from DESE estimated the sector supported 240,000 jobs. As with export value figures, many of those jobs were found outside institutions, such as the tourism providers servicing students’ family and friends. 

By the end of 2020, the sector had lost almost a quarter of its value. This worsened again, according to the latest figures from ABS, down to $26.7 billion for the 2020/21 financial year, and is predicted to fall further, to half of 2019 levels by the end of this year. 

In terms of jobs, however, things are much less clear. There is an understanding that for every three to four international students, one job is supported. Currently, the calculation isn’t as cut-and-dry. 

“We’ve probably seen more resilience in the sector than anticipated 18 months ago,” says Brett Blacker, Chief Executive of English Australia, on the employment front. 

According to Blacker, the federal government’s JobKeeper programme, announced in March 2020 to help businesses retain employees, was “predominantly the reason we didn’t see a fast cliff” in job losses. 

Still, he says, many providers in the language sector and elsewhere closed their doors, while others restructured and downsized their overheads. 

The peak body’s ongoing survey of members for the first quarter of this year found 22 percent of English language employees lost their job, primarily seasonal workers, followed by part-time and full-time staff. 

“The loss of really experienced and long-standing teachers is probably one of the primary risks that we face,” Blacker explains. 

“There are employment opportunities in other sectors that many of the teachers are accessing. Getting them back is a future risk.” 

Meanwhile, public universities, which were contentiously left out of the JobKeeper programme, shed more than 17,000 jobs in 2020. 

“Unfortunately, it is probable we will see further reductions this year,” says Jackson. 

“The loss of any, and every, one of those staff is personally devastating, bad for the university community, and Australia’s knowledge reservoir.” 

Distant thunder 

Outside the education sector, how the drop in international students affects jobs is also unclear, however, Bowmaker says the impact on Cairns, which traditionally attracts larger numbers of short-term students, has been dramatic. 

“We didn’t have those students that live here for several months to several years spending money,” she says. 

“You would not recognise the city walking through it because of the amount of shops that have closed down.” 

Store closures, however, are just one concern for the Australian labour force, says Bowmaker. 

In late 2019, the Australian government put into place new post-study work incentives to encourage international students to study outside the major three cities, Sydney, Melbourne, and Brisbane, with the goal of alleviating population pressures and boosting regional hubs. 

Post-study work rights (PSWR), available to Bachelor’s degree graduates or higher, were introduced in 2013 with multiple aims, including attracting more international students, to later benefit from their skills and talents. It was one of the primary factors in Australia’s big gains from 2015 onwards. 

Key to the 2019 changes were bonus years of work, up to two depending on location, for those who studied and lived in Australia’s regions. Bowmaker says the policy adjustment had been working. Now, however, not only are students unable to enter the country to access those work rights, but the workforce is losing access to high-quality graduates. 

“Our students [were] taking up positions in Cairns in [areas such as] health, medicine, and engineering,” she says. 

“We’re seeing that impact everywhere.” 

Lost and running 

While there are key policy differences from ten years earlier, there are stark similarities between how the decade began and how it ended. 

2011 saw Queensland make global headlines when capital city, Brisbane, experienced extreme flooding for the first time in almost 40 years. In 2019, the whole of Australia made the front pages worldwide as bushfires raged throughout the end of the year and into 2020. 

The bushfires led to the development of the Global Reputation Taskforce in January 2020 to minimise negative perceptions of Australia as a study destination, says Phil Honeywood, Chief Executive of the International Education Association of Australia. 

By February, the taskforce, which came in addition to the Council for International Education, a group comprising both ministers and industry experts set up as part of 2016’s National Strategy, quickly shifted focus towards maintaining the country’s reputation in the face of the pandemic. 

“We had 18 meetings and it seemed to work really well. We had edtech, accommodation providers, education agents all represented,” Honeywood explains. 

Eventually wrapping up in August 2020, Honeywood says the legacy on the taskforce he chaired continues now, with a new group of stakeholders established this year to meet regularly and discuss strategy and opportunities. 

Membership is also much broader than both the Reputation Taskforce and Council, he says, bringing in state government representatives, and linking with industry partners, such as airliner Qantas. 

Honeywood, however, concedes the past 18 months has seen Australia’s reputation falter. 

Student welfare and service provision in 2020, according to Belle Lim, President of the Council of International Students Australia (CISA), did not meet expectations. While several states and city councils provided a number of support programmes, such as accommodation vouchers and food banks, a national response was not rolled out. 

Lim tells QS-GEN her organisation, which serves as the voice of international students, received messages from many who said they were struggling mentally and financially. The messaging to those outside of Australia, she adds, left many students in the dark. 

“We are very disappointed and upset about the messages or the lack of messaging that went to offshore students,” Lim says. 

“These students have invested so much, not just financially, but emotionally for their education here in Australia. Not having those compassionate responses to these students is absolutely unthinkable, unimaginable.” 

Matters worsened in April 2020, when Prime Minister Scott Morrison effectively told students to leave. 

“If they’re not in a position to be able to support themselves, then there is alternative for them to return to their home countries,” he said. 

Honeywood notes several ministers later attempted to clarify the PM’s comments, arguing he was taken out of context. 

Some of the more harshly perceived comments by Morrison, particularly the line “it is time, as it has been now for some while… to make your way home”, were also conflated with his remarks towards students, and paraphrased as “it’s time to leave”. By that part of his press conference, he was referring to tourists on visitor visas. 

Still, regardless of the intention, Honeywood says the comments have had to be overcome. 

“That… really sent all the wrong messages about Australia as a safe, welcoming, supportive study destination country,” he says. 

Lim, more succinctly puts it: “When you talk to students, they still remember.” 

Last plane out of Singapore 

The barriers created by border closures have required education providers and state governments to think creatively in facilitating the safe return of international students. Even in late July, plans were well underway in both South Australia and New South Wales to launch pilot programmes. 

New lockdowns in both states, and elsewhere, put those plans on hold indefinitely. 

The amount of work required across multiple stakeholders and against the backdrop of sudden infection spikes, has meant since closing international borders, only one plan has borne fruit: 63 students through a pilot programme by Charles Darwin University (CDU) in the Northern Territory, the culmination of months of work, chartering a flight from Singapore. 

“We have been working closely with the Northern Territory and Australian governments to ensure the health and safety of the Northern Territory community remains the highest priority,” CDU’s Deputy Vice-Chancellor of Global Strategy and Advancement, Andrew Everett, said at the time. 

Razor’s edge 

Set-backs have a broader reach beyond their location. Bowmakers says stakeholders in every state have produced proposals, but situations like the recent lockdowns in Sydney, almost 2,000 kilometres away from Cairns, dampened spirits and delayed further planning. 

Subsequently, it is difficult to determine when large scale plans to bring back international students might begin, stakeholders tell QS-GEN. Minister for Education and Youth Alan Tudge, however, gave some indication of the levers required to bring back students, if not a timeline. 

“Once our vaccination rate starts to get up at 70 to 80 percent… we can start to allow greater capped entry of student visa holders,” he announced at the THE Live ANZ event in early August. 

English Australia’s Blacker sees planning for a vaccination rate rather than a date as a commendable option for international educators, as it provides clear markers for when certain work needs to occur. 

“If you’ve got a milestone that you can reach, you can work back from that in terms of those other preparatory processes, the logistics, the budgeting, and all of the resources allocation that you need from a student and a provider perspective,” he says. 

In his speech, Tudge indicated the government was hopeful this phase could occur by Christmas and backed the continuation of pilot programmes in South Australia and New South Wales when again possible. 

Bowmaker, however, notes action is needed more urgently. 

“If we don’t have some sort of concrete response in the next few weeks, it does mean that we won’t see international students for the first half of next year,” she says, pointing to the time required by students to apply for and receive a visa. 

“The overall international education sector is thinking that we’re not going to see anything until the second half of next year as the best-case scenario, unless we get something happening very, very soon.” 

As countries such as the UK, US, and Canada open up and allow in international students, Australia’s sector sees itself having to overcome an additional barrier. 

“If you are a prospective student, you won’t wait for Australia,” says Lim. 

Creating a new wave 

“It’s the first time ever that we’re going to have a level playing field between all of the primary, sophisticated education countries,” posits Scott Jones, Chief Executive of global education provider Navitas. 

“The UK and Canada have come out with really aggressive policy reforms and settings recognising education is pivotal to their economic recovery. The US has just come out and stated they’re in the process of developing something very attractive and they really want to be a leader.” 

Australia has both benefited from and suffered under a push-and-pull policy effect between its main Anglophone competitors, the US, UK, New Zealand, and Canada. When, for example, Australia adopted PSWR, it came shortly after the UK scrapped theirs. 

Jones tells QS-GEN the catalyst which honed global policymakers’ focus on attracting global talent through education was the pandemic. 

“COVID’s reset where everything was before.” 

Honeywood agrees, and adds political changes elsewhere pose a challenge. 

“We’ve lost some of the advantages we had because of negative overseas government policies and personalities. Instead of that, what we have to do is really focus on what we’re so good at,” he says. 

Consequently, the cycle of international education has shortened from 10 years to 6. The National Strategy, which was in its draft stage when “Australia’s new wave” was published, is already being replaced. 

A draft, under the title Connected, Creative, Caring has already been tabled, says Honeywood. 

“With strong emphasis on the word caring,” he adds. 

Prior to the strategy’s release, Rod Jones, former Group Chief Executive and co-founder of Navitas, urged caution “that [Australia] doesn’t go over the top on [the recovery]” to prevent the pendulum swinging back too far. 

“I think Rod’s statement is still valid,” notes Scott Jones, pointing to Australia’s growing skills needs and slowing population growth. The past year saw the lowest population growth in a century. 

“If you get it out, you open it too much and people take advantage of that position, the government of the day… will come down on this like a tonne of bricks.” 

Australia’s international education sector in 2021 finds itself in familiar waters: planning a recovery and contemplating its role in the broader national context. Using the lessons they’ve learnt in the past decade, stakeholders have the experience to ensure the sector doesn’t get pulled back out to sea again. 

Chula’s ‘AICute’ innovation, an assessment tool for stroke risk

Each year, many people suffer from stroke, die, or become disabled and helpless. Although this disease is a sudden occurrence, it is not impossible to assess the risk in advance to prevent it.

The research team from the Faculty of Medicine and the Faculty of Engineering, Chulalongkorn University have worked together to invent a tool to help assess the chance of developing a stroke caused by various causes, starting with a tool to assess stroke risk caused by heart disease called “AICute”. It is hoped that the innovation will support the care given to patients in community hospitals and small hospitals in remote areas where there is often a lack of tools and cardiologists.

Higher occurrences of stroke

Thailand has approximately 250,000 patients suffering from stroke every year. In other words, every 2 minutes, one person is likely to suffer from the disease! Of these, 30 percent may die, 30 percent are severely disabled, unable to move their limbs and their mouths appear crooked, and 40 percent of patients have a chance to completely recover or have only a few remaining symptoms.

Although most patients who suffered from a stroke are in their 50s-60s, today, the age range is increasingly younger as a result of lack of physical activity and rest, smoking, substance abuse, an imbalanced diet, and chronic diseases such as hypertension, hyperlipidemia, diabetes, snoring/sleep apnea, and heart disease.

Stroke caused by heart disease is preventable if detected early

Although stroke is life-threatening if the cause of the disease is known and treated quickly, the likelihood of recovery from the disease is high and the recurrence of the disease can be reduced.

“Determining the cause of the disease is important to provide accurate and effective treatment. If the cause is not determined, there is a chance that the disease will reoccur. And when it is repeated for the second time, the third time, the chance of being disabled is increased, causing the dependency and cost increase to be borne by the caregiver,” said Wasan Akarathanawat, M.D., the Chulalongkorn Stroke Center of Excellence.

Stroke can be caused by many reasons (read more in the information box).  Each case has a different treatment approach. Currently, 18% of stroke is caused by heart disease. “Patients in this group often suffer from atrial fibrillation and valve dysfunction or cardiac hypertrophy, which leads to a risk of thrombosis inside the heart, and the clot could drift and cause blockage in the brain, resulting in a stroke.”

Inspiration in the Development of AICute   

Dr. Wasan explained that to determine the cause of stroke caused by heart disease, a thorough cardiac examination by a skilled cardiologist, echocardiography and cardiac monitoring device are needed — a factor that is still scarce in community hospitals and small hospitals in remote areas.

“Such a hospital would not be able to refer patients for detailed checkups due to the relatively high cost. Also, sending patients to large hospitals, cardiology centers or medical schools would cause congestion in hospitals. This is why the research team has chosen first to develop innovations to assess the stroke caused by the heart.” Dr. Wasan, one of AICute’s research and development team members, further explains the meaning of the AICute name “AICute spoken quickly sounds similar to the word acute, which refers to the sudden appearance of a stroke that requires immediate treatment.”

Apart from Chulalongkorn Stroke Center of Excellence, the Faculty of Medicine of Chulalongkorn University, AICute innovation is achieved through collaboration with the Faculty of Engineering of Chulalongkorn University and a group of Chula students under the auspices of Chulalongkorn University Technology Center (Chula UTC).

AICute – an easy, quick, and accurate patient assessment tool

AICute is a web application with artificial intelligence (AI) to analyze and evaluate patients for the risk of stroke from heart disease. It enables doctors in the community and small hospitals to make decisions and send patients to heart examinations more rapidly, making the treatment of stroke more effective.

Dr. Wasan explains the use of AICute “doctors who use the device simply log in through the web application and fill in 2 sets of data: patient’s symptoms and their partial history, together with 30-32 brain scans. Most of the small hospitals are already equipped with brain scan machines. The application then processes the data in about 30-32 minutes and then summarizes it into a report on the likelihood of stroke caused by heart disease.  Afterward, the practicing physician will read the results and decide if the patent should be referred to a cardiologist for further diagnosis.”

According to Dr. Wasan, AICute’s accuracy is at 92-94 percent according to the database of 40,000 high-resolution X-ray images. Moving ahead with AI development to identify the cause of stroke and save Thai people’s lives . Dr. Wasan reveals that AICute is still in the research phase and has been tested at Chulalongkorn Memorial Hospital with satisfactory results. “The research team plans to continue the research in a large group of real patients and collect data outside of Chula Hospital to improve the AI. It also develops an easy and beautiful interface that is expected to be completed around the middle of this year (2023) and open to other interested hospitals to use and develop the application together. In the long run, it will be released as paid commercial software.”   In the future, the research team also plans to develop AI to detect strokes from other causes, which may require additional databases of x-ray images and angiography.

Hospitals interested in AICute can contact Chulalongkorn Stroke Center of Excellence, King Chulalongkorn Memorial Hospital, Bhumisiri Building, 7th Floor, Zone C, or call +662 256 4000 Ext. 80724-5 .

UNAIR Faculty of Medicine alumnus shares experience as a surgeon in the United States

The Faculty of Medicine (FK) Universitas Airlangga is widely known as one of the best medical schools in Indonesia. Since its establishment in 1913 as Nederlandsch-Indische Artsen School (NIAS), the faculty has produced professional doctors in the nation’s medical field.

The alumni have built professional medical careers at the national and international levels. Iswanto Sucandy MD FACS, UNAIR Medicine alumnus class of 1997, is one of them. Currently, the Hepatopancreaticobiliary surgeon works at the AdventHealth Medical Group General Surgery in Tampa, Florida, US.

Dr. Iswanto’s career first began in 2007 when he applied for a resident doctor position. ”At that time, I wanted to study overseas, to keep gaining knowledge until I finally landed here. A fellow alumnus at UNAIR told me, ‘maybe you should explore residency programs in the US,’” he stated in Dokter UNAIR TV, The story of UNAIR FK alumnus pursuing Hepatopancreaticobiliary in the US on Monday, January 23, 2023.

To conduct a residency program in the US, he had to take the United States Medical Licensing Examination (USMLE). The examination is mandatory for both Americans and foreigners who want to practice medicine in the US. After passing the exam, he spent seven years practicing general surgery residency, including at Jefferson Abington Hospital, Philadelphia.

After that, Dr. Iswanto took a fellowship program for Minimally Invasive Gastrointestinal Surgery at Yale School of Medicine for a year. He was offered a teaching position at the University of Pittsburgh Medical Center but chose Tampa, Florida, to continue his career.

Medical career opportunities in the US 

Dr. Iswanto also shared several opportunities he has received as a professional surgeon in the US. The US government is committed to accommodating surgeons to serve the patients.

“The government funds the teaching hospitals to train the surgeons. In the US, we got the government’s funds plus salary,” he said. The government also opens residency programs in teaching and non-teaching hospitals.

“Earlier, interns were only in universities. As time goes by, the government realizes that we need more medical specialists. Therefore, they open standardized residency programs in non-teaching hospitals,” he stated.

Tips on building a medical career in the US 

To be a professional surgeon overseas, Dr. Iswanto believed that strong intention is the main key to success. Many of the doctors were unable to finish the internship program in a competitive environment.

Besides, preparing for USMLE is also required to familiarize with the exam system. “The US has its own examination system and we have to be familiar with the way it works. The problem occurs when the board tests the foreign doctors, they don’t pass as they are not familiar with the test,” he concluded.

Nogogeni ITS defends championship title at KMHE 2022

The Nogogeni ITS team, known for producing energy-efficient cars from Institut Teknologi Sepuluh Nopember (ITS), has once again triumphed at the 2022 Energy-Efficient Car Competition (Kontes Mobil Hemat Energi). The team, which represents ITS at the competition, emerged victorious in the Urban Concept Electric Motor category. The announcement was made on Thursday (3/11/2022), following the final round of the competition.

This annual competition is held by the National Achievement Center (Pusat Prestasi Nasional) by the Ministry of Education, Culture, Research, and Technology. The General Manager of the Nogogeni Team, Ghalib Fakhrizal explained that the competition requires participants to build cars with the best possible fuel efficiency. After two years of being held online, the KMHE 2022 was held on-site, located in Surabaya, at the Gelora Bung Tomo Circuit (GBT) to be precise.

Since 2015, Ghalib’s Nogogeni team has consistently participated in the Energy-Efficient Car Competition, winning awards in various categories each year. From 2019 to 2022, the team won first place in the Urban Concept Electric Motor category for four consecutive years. This year, the team competed with their Nogogeni VII Evo flagship car in the Urban Concept vehicle category, specifically in the Electric Motor energy class. The competition challenged participants to design a four-wheeled vehicle that is energy-efficient and suitable for street driving, with the race requiring the car to complete eight laps in 25 minutes.

According to Ghalib, the Nogogeni VII Evo was designed to be more aerodynamic and lightweight in order to achieve greater efficiency, which are the two primary factors in its success. The car was evaluated based on its ability to save energy and complete the race quickly, and it finished in under 25 minutes with an energy efficiency rating of 186.56 kilometers per kilowatt hour. As a result, the Nogogeni ITS Team was named the champion of the competition in its category, and Ghalib expressed hope that they will be able to maintain this title in the coming years.

Committed to instigating authentic assessment

There was a time not long ago when undergraduate and postgraduate students spent the last few weeks of each study period preparing for the pressures of examinations. For many, the process of sitting in large halls for several hours using only pen and paper to demonstrate their skills and accumulated knowledge was daunting. For others, this was the type of environment they had trained in to secure academic success and they thrived on being able to predict questions, structure answers under the pressure of time and write lucidly (and legibly). 

The events of the COVID-19 pandemic and the movement of numerous forms of learning online changed the way many business schools now think about assessment. Most business schools hold a strong commitment to ensuring their graduates are career-ready and possess contemporary skills to succeed and grow in employment. This is especially the case for universities with a strong tradition of working closely with enterprise and seeking to make a real-world impact, like the University of South Australia. And yet one of the ironies of using ‘traditional’ examinations is that these arrangements led to a portion of students who were prima facie ‘successful’ graduating while not being especially competent in the world of work. Similarly, some who struggled with traditional examinations discovered later that they had aptitudes that employers and markets valued and these were never formally assessed. 

The fact that the COVID-19 pandemic prevented large crowds being assembled in examination halls meant that new forms of assessment were rushed and pushed out to business schools, regardless of their ambitions around graduate capabilities. The first response for most was to move ‘examinations’ online, in the knowledge that it then became more difficult to control the setting under which students were assessed. Two options were generally invoked to deal with this: (1) the establishment of online proctoring, where students are monitored remotely during the course of the examination and (2) a transition to time-bound ‘open book’ assessment. The former approach allowed institutions to retain the ‘traditional’ assessment while the later moved closer to the real-world of work. 

While these events have exposed the benefits of having students perform in a ‘real-world’ setting, it has also raised challenges. Probably the most concerning has been the stresses placed on the integrity of online open-book assessments. Cheat sites have quickly promulgated, raising anxieties for some professional accrediting bodies. Nonetheless, reverting to traditional examinations as the conditions of the pandemic change runs the risk of failing to take an opportunity from this world crisis. 

The University of South Australia has committed to instigating authentic assessment in all of its programs, including those in Business. This commitment has seen academic staff create a range of assessment techniques that harness the benefits of placing students in real-world environments where they must solve genuine problems. 

In some cases, this has prompted expanded use of viva voce, where students respond verbally to questions. This need not be limited to smaller groups and can be effectively employed across large cohorts. The process can also be undertaken in-person or online and often better reflects the environment where many business graduates will operate. 

In other cases, especially where quantitative problem solving is valued, students are set tasks that require careful use of spreadsheets and analytical software. Automatically randomizing the questions and making the tasks timebound has controlled the integrity of the process. Again, this has also led to better outcomes in terms of preparing graduates. More particularly, students increasingly understand the need to produce high quality and defendable responses within a time constrained environment; precisely the type of environment where many will operate. There is also the opportunity for the student to show initiative.

Beyond Lithium: a promising cathode material for magnesium rechargeable batteries

Magnesium is a promising candidate as an energy carrier for next-generation batteries. However, the cycling performance and capacity of magnesium batteries need to improve if they are to replace lithium-ion batteries. To this end, a research team focused on a novel cathode material with a spinel structure, Mg1.33V1.67−xMnxO4. Following extensive characterization and electrochemical performance experiments, they have found a specific composition that could open doors to high-performance magnesium rechargeable batteries.

Lithium-ion batteries have remained unrivaled in terms of overall performance for several applications, as evidenced by their widespread use in everything from portable electronics to cellular base stations. However, they suffer from few important disadvantages that are difficult to ignore. For one, lithium is rather expensive, and the fact that it is being mined at an extreme pace does not help. Moreover, the energy density of lithium-ion batteries is not enough to grant autonomy to electric vehicles and heavy machinery. These concerns, coupled with the fact that the batteries are highly unsafe when punctured or at high temperatures, have caused scientists to look for alternative technologies.

Among the various elements being tested as efficient energy carriers for rechargeable batteries, magnesium (Mg) is a promising candidate. Apart from its safety and abundance, Mg has the potential to realize higher battery capacities. However, some problems need to be solved first. These include the low voltage window that Mg ions provide, as well as the unreliable cycling performance observed in Mg battery materials.

To tackle these issues, a research team led by Vice President and Professor Yasushi Idemoto from Tokyo University of Science, Japan has been on the lookout for new cathode materials for Mg batteries. In particular, they have been searching for ways to improve the performance of cathode materials based on the MgV (V: vanadium) system. Fortunately, as reported in a recent study made available online on 8 December 2022 and published in Volume 928 of the Journal of Electroanalytical Chemistry on 1 January 2023,  they have now found the right track to success.

The researchers focused on the Mg1.33V1.67O4 system but substituted some amount of vanadium with manganese (Mn), obtaining materials with the formula Mg1.33V1.67−xMnxO4, where x goes from 0.1 to 0.4. While this system offered high theoretical capacity, more details about its structure, cyclability, and cathode performance needed to be analyzed to understand its practical utility. Accordingly, the researchers characterized the synthesized cathode materials using a wide variety of standard techniques.

First, they studied the composition, crystal structure, electron distribution, and particle morphologies of Mg1.33V1.67−xMnxO4 compounds using  X-ray diffraction and absorption, as well as transmission electron microscopy. The analyses showed that Mg1.33V1.67−xMnxO4 has a spinel structure with a remarkably uniform composition. Next, the researchers conducted a series of electrochemical measurements to evaluate the battery performance of Mg1.33V1.67−xMnxO4, using different electrolytes and testing the resulting charge/discharge properties at various temperatures.

The team observed a high discharge capacity for these cathode materials—especially Mg1.33V1.57Mn0.1O4—but it also varied significantly depending on the cycle number. To understand why, they analyzed the local structure near the vanadium atoms in the material. “It appears that the particularly stable crystal structure along with a large amount of charge compensation by vanadium leads to the superior charge–discharge properties we observed for Mg1.33V1.57Mn0.1O4,” remarks Prof. Idemoto. “Taken together, our results indicate that Mg1.33V1.57Mn0.1O4 could be a good candidate cathode material for magnesium rechargeable batteries.”

Satisfied with the present findings and hopeful about what is to come, Prof. Idemoto concludes: “Through future research and development, magnesium batteries could surpass lithium-ion batteries thanks to the former’s higher energy density.”

Indeed, substituted MgV systems could eventually lead to the much awaited next-generation batteries. Let us hope the highly anticipated alternative to lithium for our rechargeable battery needs will be realized soon!

ITS and Panasonic Collaboration Launches Indonesian-Made LED Bulbs

Institut Teknologi Sepuluh Nopember (ITS) is committed to continuing its technology development collaboration with the industrial world and government. This year, ITS has collaborated with PT Panasonic Global Life Solution Manufacturing and the Pasuruan City Government to produce an Indonesian-made LED bulbs, which were officially launched and marketed on Friday, January 20th, 2023.
As one of the efforts to work on the Bangga Buatan Indonesia (BBI) national movement, ITS collaborated with industry and government through the Kedaulatan Indonesia dalam Reka Cipta (Kedaireka) program from the Ministry of Education, Culture, Research and Technology (Kemendikbudristek). ITS Rector, Prof. Mochamad Ashari, mentioned the hard work of ITS academics, the Pasuruan City Government, and PT Panasonic Gobel Life Solution Manufacturing in creating the product.
The launch of the BBI LED Bulbs marks a major step forward in meeting the high demand for lamps in Indonesia. On average, each Indonesian household needs at least five lamps, adding to the already immense need for lamps in the country. This collaboration has doubled the production capacity of lamps from 50 million per year to 100 million per year, helping to not only meet the demand in Indonesia but also in the export market.
This collaboration is part of an effort to raise the level of domestic components (TKDN) in Indonesia’s electronics industry. The BBI LED Bulbs come in 14 models with seven voltage options, allowing customers to choose the right lights for their needs. The bulbs are also equipped with anti-blue light and anti-flicker technology to protect the eyes and improve lighting comfort, productivity, and energy efficiency. During the launch, the ITS Rector, Director of PT Panasonic, and Deputy Mayor of Pasuruan visited the factory to inspect the manufacturing process. It is expected that this collaboration will bring benefits to many parties by boosting national LED bulb production and improving the well-being of the people
