Around 99.5% of Thailand’s 67 million population enjoys health protection coverage. Majority of it, nearly 70%, is provided by the public sector. Universal Health Coverage was launched in 2002, leading to falls in infant and child mortality and rise in life expectancy. Thailand has good healthcare indicators, compared to peers. IT has played a crucial role in these developments.
OpenGov speaks to Dr. Polawat Witoolkollachit, Director of Information Technology and Communication, Ministry of Public Health, Thailand to learn about the journey till now and the path ahead. He has been involved in many public health related IT projects, including the setting up of an inter-connected data centre network across Thailand.
Could you please describe your current areas of focus?
In the next three years, our focus is on E-Health strategy and adapting it to our policy. We follow the World Health Organisation (WHO) guidelines. The WHO has the Health Systems Framework, which consists of six building blocks. Their main objective is to improve the delivery and quality of healthcare to the people. Some of these blocks involve the use of health information technology to improve health care.
Now we are in the phase of implementing the E-health policy in our healthcare system.
What are the projects your department is working on?
Our department is involved in many projects about developing the infrastructure of health IT in Thailand. First, we try to get our service units in place. We have over 10,000 units all over Thailand, connected together. The connection was completed 2 years ago.
Now, every single unit in Thailand can send and receive information from the Ministry of Public Health (MPH). We can monitor and deliver the report of the individual service units, tracking the quantity and quality of services delivered.
We have about 76 provincial health offices. Every provincial health office has their own data centre. They are connected to each other and to the central data centre. After we implemented health data centres, we have to implement big data tools (Axis MOPH: Bigdata project). When we collect the data from all the provincial units and try to get a holistic view, we need to use big data analytics. To manage the data at the ministry level, we are using big data servers.
Can you please give some examples of big data use in public health sector in Thailand?
If we want to get a report from some province, now we can easily access a pre-prepared report on regular matters of interest, we can get the result instantly (http://hdcservice.moph.go.th). If we want to know something different from the regular issues, we use our big data server to retrieve that information.
For example, earlier if we wanted current statistics on pregnancies, you would have to call and get the data from every province and tie it all together into a report. With big data, you can get the information in nearly real-time. It is almost instant, taking less than 30 minutes.
Previously, we were trying to find how many Outpatient department (OPD) cases we had from January till now. Even after the implementation of provincial data centres, we had to go to every data centre, submit the query and collate the results. Now we can go to the AXIS big data server, and get the instant report.
What kind of training program was used for enabling stakeholders to utilise data centres?
We have a 3 level training structure. The first one is for the users at the ground level. They are trained to use the Health Data Centre Service to generate regular reports.
Users in the service units all over Thailand are trained, so that they can use their health data centre reports and compare them to others. They can also check the history of their actions and numbers.
The second rung of training is for administrators at the provincial level. They can monitor the data, extract any data they need from the provincial data centres, and check its integrity before sending it to the ministry.
The third one is for administrators at the ministry level. We train them how to use the data.
Because Thailand has health care service data sets from 20 years, now we have the fourth generation of data sets, administrators at the ministry level can analyse the data. They can check gaps and defects in the data and work towards making it complete. They are also taught and trained how to use big data.
Earlier, we never know the impact of a policy till we were done, or at least till the end of the year. Now, we can monitor what’s going on.
How do you evaluate the success of these projects?
The key to success for us is the number of users and the number of reference reports they generate using our service. As you know, if we implement advanced technology applications but if they don’t use it, then it is futile. There is no value go it. Finally, if people do not use it saying it is unreliable, then it is a failure of the system.
But our systems are becoming more popular day-by-day because reports from our applications are being widely used to monitor and evaluate results.
Can you please give some examples of the use of big data in public health care in Thailand?
In referral cases, when a patient is sent to a specialist hospital, they don’t need to re-enter the data at the hospital. The patient does not need to answer the same questions over and over again. We can identify the people and send some of the personal data through our systems to the other hospital.
The information transferred is kept within the bounds set by our laws. We can use our product to connect to the Ministry of Interior in order to check the integrity of data. When we want to do something with personal information of the patient, we have to authenticate the data first, check the identity of the persons.
Thailand is different from other countries in the region, because nearly 80% of the 67 million population of Thailand rely on the public healthcare system and we have Universal Health Coverage. This makes us the family service provider for any citizen in Thailand. So, we have to take care of more citizens, compared to other countries. Private sector handles less than 35% of total health services.
What is the next step for IT in the Thai health care system?
The next step we are looking to is a Health Information Exchange (HIE) for personal health records. It is our goal to achieve that in the next three years. If you have health problems while living in one province, and then you move to another province, your record is not moveable. You have to ask them to send the record to the other hospital where you are using the service at present. With the HIE, the information of Thai citizens can follow them anywhere in Thailand.
There are several by-products or side-benefits of centralised personal health records. You can use it for administration, you can use it to improve health care services, citizens can use it for their own health-related purposes.
Without personal records system, medical history is very difficult to access. You might not remember something for your own child, from when they were young. You might not know something related to your parents.
If you can monitor yourself, then it good for the overall health care system. If you can do more prevention, it will reduce costs for the system in the long term.
We have a Personal Health Records Board. It also includes many of the health care providers and all professional councils. Participation is voluntary but they are all coming together to make it happen, to make the HIE a reality.
In relation to centralised personal health records, there is a lot of concern over cybersecurity? How are you managing those risks?
We include the Attorney General and representatives from the ETDA (Electronic Transaction Development Agency) in the working council. We factor in security in the design and planning. This gives us confidence that we can establish a secure HIE.
What are the key challenges in ICT-related projects in the public health sector?
The key is always leadership. First is leadership, which flows into strategy and policy, and then comes collaboration between stakeholders.
Leadership has to be aligned with the people, with the citizens in Thailand, with their needs. Communication needs to happen with every level of top leadership and administrators, regarding the importance of IT and what we need to do in the next few years.
External pressure by the people and internal pressure within the government will move Thailand towards not just a digital healthcare sector but also a digital government and digital economy.
The 13th Singapore-US Strategic Security Policy Dialogue (SSPD) was convened, and co-chaired by Permanent Secretary of Defence, Chan Heng Kee and United States Acting Under Secretary of Defense for Policy, Sasha Baker. This dialogue, embedded within the 2005 Strategic Framework Agreement and Defence Cooperation Agreement, serves as a cornerstone for shaping the future of Singapore-US defence relations.
Beyond the traditional domains of defence, Singapore and the US are venturing into uncharted territory – cybersecurity and critical emerging technologies. This signifies a strategic shift that acknowledges the evolving nature of security threats in the digital age.

The dialogue also featured discussions on regional developments and the continued engagement of the US in the Asia-Pacific region. The ASEAN Defense Ministers’ Meeting (ADMM)-Plus framework serves as a platform for constructive dialogue and cooperation among ASEAN member states and their partners. Singapore and the US both recognise the significance of this framework in promoting regional stability and security.
Regular bilateral and multilateral training exercises form another vital facet of this partnership. Exercises like Tiger Balm, Pacific Griffin, Commando Sling, Red Flag, and Super Garuda Shield serve as platforms for joint training and skill development. These exercises not only enhance the operational readiness of both armed forces but also foster greater cooperation and understanding between Singapore and the US.
One noteworthy aspect of this collaboration is the US’s support for SAF’s overseas training, exemplified by Exercise Forging Sabre. This training, conducted at Mountain Home Air Force Base, Idaho, has played a pivotal role in honing the skills of RSAF personnel.
In 2023, two RSAF detachments, Peace Carvin II (F-16 fighter aircraft) and Peace Vanguard (Apache AH-64 helicopters), marked their 30th and 20th anniversaries of training in the US, respectively. These milestones are a testament to the enduring nature of the Singapore-US defence relationship.
The 13th Singapore-US Strategic Security Policy Dialogue not only reaffirmed the steadfast commitment of both nations to their long-standing defence partnership but also showcased their readiness to adapt to the evolving security landscape.
As reports cited the inclusion of cybersecurity and critical emerging technologies in the discussions reflects the forward-thinking approach to safeguarding the national interests of both nations. As they continue to train together, exchange knowledge, and invest in cutting-edge technologies, Singapore and the US are poised to navigate the complex challenges of the future, hand in hand.

The Centre for Memory Studies at the Indian Institute of Technology, Madras (IIT-Madras) has introduced the ‘MovingMemory’ application, which harnesses both augmented reality and virtual reality (AR/VR) technologies to capture diverse moving models of memory through digital reconstruction. It was designed to enhance the tourist experience at cultural and heritage sites. It offers virtual tours of famous places in India.
The app’s features allow users to choose their preferred avatar and navigate through three-dimensional spaces. According to a statement from IIT-Madras, it is embedded with additional layers of video, audio, 3D images, and interactive elements which may be used as models for sustainable and heritage-oriented pedagogic and research approaches.
Once the app becomes available to the public, MovingMemory can be accessed from both Android and iOS devices, as well as through browser-based platforms, setting it apart as a uniquely inclusive application. It is a spatial app created with the capability to exist within the metaverse realm.
MovingMemory was introduced at the second annual conference of the Indian Network for Memory Studies, titled ‘Memory, Ecology, and Sustainability.’ It was organised jointly by the Indian Network for Memory Studies and the Centre for Memory Studies at IIT- Madras. It covers a wide range of human-centred technologies and policies related to cultural memory and sustainable development goals, both within India and on a global scale.
At the inaugural event, IIT-Madras Director, V. Kamakoti, said, “It is crucial that we foreground the urgent need to incorporate collective memory in our understanding and ability to anticipate policies related to ecological issues such as climate change. Human as well as non-human forms of memory (such as the memory of water and the memory of nature) such as the Spanish Flu and the 2015 Chennai floods may be studied through interdisciplinary and collaborative formats in order to further memory studies as a discipline.”
The conference aims to connect rituals of remembering and experiencing the environment to systems of sustainability, which assume material, cultural, and technological dimensions through significant events like disasters and floods and long-term processes of change.
The international conference attracted approximately 100 presenters and more than 500 attendees from across India, the United States, the United Kingdom, Germany, New Zealand, Morocco, Canada, Sweden, Bangladesh, and other countries.
An official at the event said that the conference, like all other research activities at the Centre for Memory Studies at IIT-Madras, seeks to bridge technology studies and humanities. Its purpose is to provide a more complex model of engaging with memory, ecology, and sustainability, while also connecting to issues such as disaster studies, anticipatory governance, and durability.
Another expert from IIT-Madras noted the importance of reexamining pre-modern modes of memory and resilience and integrating those with the post-modern modes through which ecology and sustainability practices may receive a more nuanced understanding. These interdisciplinary practices have triggered a paradigm shift in both humanities education and research.
IIT-Madras has undertaken several initiatives in the field of AR/VR. In April, it announced it was developing instructional and educational models that use AR/VR technologies, aimed at assisting secondary schools in rural regions of the country. As OpenGov Asia reported, the initiative provides students with unique opportunities to engage in immersive and experiential learning through VR-enabled technology. Subjects like social science, history, sciences, and languages can be effectively taught using AR/VR world-building, digital storytelling, and educational games. An inaugural AR-based mobile app was launched to capture the history of the transnational Anglo-Indian community across 500 years.
Indonesian Foreign Minister Retno Marsudi highlighted the digital dimension in the country’s counter-terrorism strategies during her recent address at the Ministerial Plenary Meeting of the Global Counter-Terrorism Forum (GCTF) in New York.
Minister Retno emphasised the significance of comprehensive rehabilitation and reintegration (R&R) efforts within Indonesia. Notably, these efforts extend beyond former terrorist inmates, encompassing strengthening communities and the environments that receive them. The focus on digital aspects of R&R is evident in Indonesia’s approach.
Indonesia has adopted a multifaceted strategy to counter extremism, as outlined in its National Action Plan for Prevention and Countering Extremism. This strategy underscores the “whole-of-government” and “whole-of-society” approaches, highlighting the collaborative roles of the government and civil society. Combining hard and soft approaches, Indonesia actively engages communities and fosters international cooperation in its counter-terrorism efforts.
The digital dimension is also prominent in Indonesia’s second pillar of counter-terrorism strategy, which aims to harness technological advancements while ensuring they are not misused for extremist purposes. The rapid evolution of technology has created opportunities for disseminating extremist ideas, demanding constant vigilance. In response, Indonesia introduced the “Pusat Pengetahuan Indonesia (I-KHub),” or the Indonesian Knowledge Hub.
I-KHub is not merely a digital repository of information but a dynamic platform that actively contributes to Indonesia’s counter-terrorism endeavours. Integrating data systems and facilitating evidence-based decision-making empowers policymakers, law enforcement agencies, and community leaders with actionable insights.
One of the critical features of I-KHub is its ability to analyse trends and patterns in extremist activities. Leveraging advanced data analytics, it can identify emerging threats and hotspots, allowing for proactive measures to be taken. This early warning system is instrumental in preventing extremist ideologies from taking hold in vulnerable communities.
Moreover, I-KHub is a collaborative space where experts, researchers, and stakeholders from various sectors can share knowledge and best practices. This collective intelligence enriches the understanding of extremist narratives and recruitment tactics and facilitates the development of effective counter-narratives.
The platform’s outreach extends to educational institutions, where it supports curriculum development aimed at countering extremism. I-KHub is vital in promoting digital literacy and critical thinking among students by providing educators with relevant resources and insights. This proactive approach helps inoculate young minds against the allure of extremist ideologies.
In the digital realm, I-KHub monitors online spaces where extremist content proliferates. It can promptly identify and report such content through advanced algorithms and data analysis. This collaborative effort with tech companies and social media platforms contributes to removing extremist material from the internet, disrupting the digital recruitment efforts of extremist groups.
The third aspect of Indonesia’s counter-terrorism strategy focuses on creating a secure environment to counter extremism. This includes digital-driven educational programmes targeting women and children. Minister Retno highlighted that extremist ideologies thrive in environments rife with hatred, emphasising the role of digital tools in promoting understanding, tolerance, and peace.
In her closing, Minister Retno expressed that GCTF member countries would firmly commit to ensuring the inclusive implementation of the R&R strategy. The Global Counter-Terrorism Forum is a vital international platform for global cooperation and information exchange on counter-terrorism and violence-based extremism.
Indonesia underscores the country’s commitment to harnessing technology for a safer and more peaceful society. Indonesia’s multifaceted counter-terrorism approach, particularly its emphasis on digital knowledge sharing through I-KHub, reflects its dedication to addressing the global challenge of extremism with modern tools and strategies.
Chinese Vice Premier Zhang Guoqing emphasised China’s resolve to promote high-level openness in the digital sphere at a time when global digital cooperation was at a turning point. This announcement was made during the second high-level digital conversation between China and the EU which Zhang and Vera Jourova, Vice President of the European Commission, co-chaired.
The meeting was a big step forward in the ongoing conversation between China and the EU. They talked in depth about many important issues in the digital world. The growing field of artificial intelligence (AI), communication technology standards, the moving of data across borders, and the safety of non-food items were some of the topics that people were interested in.
These discussions had positive results, highlighting the possibility of cooperation and understanding between these two significant figures on the international scene. The recognition of China and the EU’s complementary roles in the digital sphere and their common interests was a recurring subject in the talks.
To support the expansion of the digital economy, both parties were unwavering in their resolve to cultivate a cooperative spirit, further improve exchanges, and create an environment that is open, inclusive, impartial, fair, and non-discriminatory. This concerted effort has the ability to not only spearhead the global digital transformation but also make a major contribution to the ongoing global economic recovery process.
At the heart of this cooperative spirit is Zhang’s call to businesses everywhere, particularly those in Europe, to take advantage of the growing prospects China’s digital economy offers. This invitation highlights China’s willingness to interact with other countries and signals a new era in which win-win scenarios and cooperative relationships are not only welcomed but actively pursued.
Vera emphasised the solid basis and promising future of cooperation between China and the European Union in the digital domain affirming that the EU is keen to engage in practical cooperation with China in a range of pertinent topics, to facilitate more thorough interactions, and to expand conversation. A forward-thinking strategy that crosses boundaries and capitalises on the combined strengths of nations is exemplified by the reciprocal readiness to investigate opportunities for collaboration.
This conversation has far wider implications than just the meeting space. It represents a coming together of interests and an understanding of how interwoven the world’s digital landscape is. Partnerships like these have the power to influence the course of innovation and development in an era where digital technologies drive economies, industries, and communities.

These innovations are expected to have a profound impact across diverse sectors, including energy, advanced manufacturing, healthcare, and agrifood, all vital for NSW’s future economic growth.
The Minister leading this initiative underscored the government’s commitment to nurturing a robust innovation sector. In his view, a thriving innovation sector not only creates high-value jobs but also enhances productivity within high-growth industries. The government believes that by fostering innovation and cutting-edge industries, it can secure the jobs of the future and attract top-tier talent to NSW.
Thus, the NSW Labor Government is working to revitalise NSW’s innovation sector through collaborative efforts with universities, businesses, and sector experts. This initiative addresses longstanding challenges in university-industry collaboration and the need to reverse declining R&D intensity.
While fiscal responsibility is paramount, the government recognises that strategic investments in innovation are essential for NSW’s long-term prosperity. Through the Innovation Blueprint, NSW aims to position itself as a global leader, attracting investments, talent, and industries that will define the future.
OpenGov Asia recently reported that the Government of Western Australia is offering over AU$3 million in grants through the Local Capability Fund (LCF) to boost local small to medium-sized businesses. These grants aim to enhance their competitiveness and capacity, making them eligible for government and private sector contracts.
This initiative aligns with the Minns Labor Government’s Innovation Blueprint in New South Wales (NSW), which seeks to drive innovation and economic growth. While the LCF focuses on empowering local businesses to secure contracts, the Innovation Blueprint in NSW takes a broader approach, promoting innovation across various sectors.
Both initiatives share the goal of fostering economic development. The LCF in Western Australia offers targeted support, including assistance for Aboriginal-owned businesses, compliance with national and international standards, and upcoming digital transformation support. These align with the Innovation Blueprint’s focus on innovation in sectors like energy, healthcare, and advanced manufacturing.
Collaboration is key in both efforts. Western Australia partners with local businesses, while NSW collaborates with universities, businesses, and experts. These initiatives collectively contribute to enhancing Australia’s economic landscape by empowering local businesses and driving technological advancement.
The technology landscape constantly seeks high-power, energy-efficient devices. 3D-stacked electronics offer exciting potential, but overheating is a challenge due to their compact design. Excess heat can cause performance issues and damage. Thankfully, a new solution involving magnetic fields and innovative materials has emerged to address this challenge, ensuring these devices remain cool and efficient.
At the forefront of this breakthrough is a team of scientists led by Assistant Professor Hortense Le Ferrand of the Nanyang Technological University of Singapore – School of Mechanical and Aerospace Engineering. They have embarked on a journey to tame the heat generated by 3D-stacked electronics and ensure they operate at peak performance.
The key to their innovation lies in a material called hexagonal boron nitride (BN), known for its exceptional heat-dissipating properties. To make BN responsive to their needs, the researchers coated microscopic BN particles with iron oxide. This strategic move rendered the particles magnetic, paving the way for precise control.
Next, they suspended these coated particles in a solvent and brought magnetic fields into play. The magic happened as the magnetic fields aligned the BN particles in various orientations. This alignment turned out to be the key to effective heat management.
The team conducted rigorous tests to gauge the heat-dissipating capabilities of these precisely oriented BN particles. What they discovered was nothing short of revolutionary: when the particles were aligned vertically, they proved incredibly efficient at channelling heat away from their source. This breakthrough alone promised a significant leap forward in the cooling technology of high-power devices.
But the innovation didn’t stop there. The orientation of the particles could also be tailored to direct heat in different directions, a flexibility that opens a world of possibilities. For instance, when these particles find themselves sandwiched between two heat-emitting electronic components, they can be configured to direct heat sideways, ensuring optimal thermal management.
Assist Prof Hortense believes this novel approach to aligning and orienting BN particles offers exciting new prospects for managing heat in high-power electronic devices. It’s a promising development that could pave the way for the widespread adoption of 3D-stacked electronics, ushering in an era of high-performance, energy-efficient devices without the nagging concern of overheating.
Preventing high-power devices ensures sustained performance. Overheating can cause these devices to throttle their performance or even shut down altogether. This can have a significant impact on productivity and functionality, especially in critical applications.
Further, managing heat is crucial for the longevity of these devices. Excessive heat can damage internal components over time, leading to a shorter lifespan. This, in turn, can result in frequent replacements, which can be costly for both consumers and manufacturers.
Besides, there are safety concerns associated with overheating. In extreme cases, it can pose a fire hazard or create electrical safety risks. Proper heat management is vital to mitigate these dangers and ensure the safe operation of high-power devices.
Efficient cooling also contributes to energy efficiency. When devices operate within their optimal temperature range, they consume less power. This not only reduces energy costs but also lessens the environmental impact.
Also, reliable operation is paramount for high-power devices, particularly in critical applications like medical equipment and aerospace technology. Overheating can lead to system failures, which may have severe consequences; hence, effective heat management is crucial to maintain the reliability of these devices.
