Dementia patient care centre system, Android application for person-centered care, PEAR front end system
No full textWith a global aging population, dementia sufferers are expected to increase in the next half century. There is no cure to dementia condition as of today and this has sparked motivation for researchers around the world to bring about a breakthrough in treatment in time to come. There is a need for coordinated effort to track the evolution of the disease, create policies to address the impact of dementia and lastly to conduct treatment and having effective care for existing dementia patients.
Study has shown that person-centered care is proven to improve patient’s dementia condition by providing caregiver support and family experience. Person-centered care considers the individual’s unique abilities, interests, preferences and needs as compared to medicinal treatment that considers symptoms and behaviours. However due to the lack of resources, it is a big challenge for healthcare providers to provide such treatment.
This project aims to improve the efficiency outputs of person-centered care centres with the implementation of Information Technology (IT), specifically on the front end system named PEAR which interacts directly with the patient and working personnel. Using the User Interface (UI) design done up by the predecessor of the project Sutrisno Suryajava Dwi Putra as reference, the author continues to further develop new functionalities such as creating an interface for patient’s to have their own photo album and a game interface which relates to the list of assigned games for patient’s as well as providing dynamic database entries into the backend of the system. The author also works closely together with his teammate Keith Tay Tat Leong in developing other aspects of the front end of the system such as app notification and other functionality.
PEAR was developed with maintainability, flexibility and user experience as the main focus as stated in the predecessor’s notes and written documents. The author believes that with the continuous development of the system, it will then provide better efficiency outputs of person-centered care. The author also believes that the project will be easily handed over to the new FYP students to improve on the system outputs.Bachelor of Engineering (Computer Engineering

Person-centred care for dementia patients (Backend system)
No full textDementia is an illness that leads to the gradual decline of the brain and its abilities in judgement, language, planning and behaviour. Statistics has shown that there are approximately 22,000 cases of dementia patients aged 65 and above in Singapore [1]. This figure is projected to rise to a total of 53,000 in 2020 and a further increase to 187,000 in 2050 [2].
As such, PEAR – dementia care centre system has been put into development. The project is designed and developed by three main teams – Android Game Development team (AGD), Person-Centred Care team (PCC) and Backend System (BS) team.
The BS team comprises of two members – the author and another member (Janice Yak Zhen Qi). Together, the BS team’s project objective is to develop a backend system and a game manager.
The backend system shall be used to support the operations of the AGD and PCC team. It comprises of two main components, a database which is used for storage of data and a web interface.
The database shall be the primary storage of data pertaining to patients, which shall be used by the AGD team, PCC team and the BS team. Thus, the database must be designed and implemented in a manner that facilitates maintainability and flexibility (the ability of the database design to incorporate new requirements for future development of the project).
The web interface shall serve as the primary access points for two main users – Doctors and System administrators. Through the web interface, System administrators shall be able to manage user accounts and games. Additionally, doctors shall be able to keep track of patients’ dementia status and perform actions such as prescription of game categories, generation of game list recommendation and performance analysis of patients’ medication condition based on records of games played by patients.
Furthermore, a game manager shall be developed. The game manager shall serve as the integral point between the AGD team and PCC team in uploading the games scores of the games played by patients to the database.
Being the pioneer batch to develop the backend system, the BS team set maintainability and flexibility as the main quality attributes. The author strongly believes that the project shall be further developed by future FYP students, improving the ability for dementia care centres to manage the dementia patients within.Bachelor of Engineering (Computer Science
Android tablet game development for dementia patient - Games
No full textOver the years, Singapore is experiencing an increase in silver generation. By 2030, the nation will join 33 others as a “super-aged” country, where one out of five people are aged 65 and older. Given this rise, we can also expect an increase in the prevalence rate of mental disease like dementia.
Most of the mental diseases are incurable. However, researchers have shown that dementia can be prevented or slow down by having early preventive measures. One of the best preventive measures is the use of technological devices like iPad and tablets. Mobile application has the ability to stimulate brain in a fun and interactive environment.
The objective of this project is to create mobile game applications that can help to improve a dementia patient’s condition. Unlike many other games in the market, games developed in this project are able to capture more in-game behaviour of the player. The data captured from the game will be passed to the PEAR database to do further analysis on the patient’s condition.
The games developed in this project will be added into the current PEAR system. There are 6 main categories of game in PEAR system; Speed, Memory, Attention, Flexibility, Problem Solving and Mind-eye Coordination.
In this project, the author has developed 2 Android tablet games. The first game is called RevertBack. This is a new game that is categorised under memory category. The goal of RevertBack is to tackle the problem of misplacing item. The game trains the memory skill of the patient by testing them on getting the items back to their original positions after mixing up the items order. Unlike normal games in the market, RevertBack is able to capture more in game behaviour like the number of swaps, item category, whether hints are activated. The second game, PuzzleV2, is a revamped version of a created game called Puzzle. This game is categorised under flexibility and mind-eye coordination. The game trains the recognition skill of the patient by testing them on re-building a picture using a jigsaw puzzle game. Both games are designed under the consideration of elderly. The use of larger fonts and vibrant colours improves readability for elderly. Furthermore, both games are also available in English and Chinese to cater to a wider range of elderly user.
With the aid of mobile game, the author hope to lighten the burden of caregivers who are working in the day care centres, as well as family member of the dementia patient.Bachelor of Engineering (Computer Science
Person-centred care for dementia patients (backend system development)
No full textWith the rising prevalence of dementia amid an aging population, effective digital healthcare
solutions are crucial. The Person-Centered Care (PEAR) system addresses this need by providing caregivers and healthcare professionals with robust, integrated tools for patient management and monitoring.
Central to this iteration of the PEAR project is the migration from a legacy monolithic .NET
architecture to a scalable microservice design. The author focused significantly on designing and
implementing the Patient and Logger microservices. These microservices improve
maintainability, scalability, and performance by clearly defining domain-specific functionalities.
Challenges were encountered in disentangling the tightly coupled legacy codebase, necessitating meticulous analysis and strategic database restructuring. Additionally, a comprehensive logging solution was developed using Elasticsearch, Logstash, and Filebeat (ELK stack), providing efficient log aggregation, indexing, and retrieval.
In parallel, the author spearheaded the redevelopment of the web frontend, transitioning it from
outdated HTML/CSS and JavaScript embedded within the C# monolithic structure to a modern,
modular stack leveraging Next.js, Shadcn, and TypeScript. This transition introduced enhanced
maintainability, clarity in separation of concerns, and robust unit testing frameworks to validate
frontend components.
Further contributions included the establishment of Continuous Integration and Continuous
Deployment (CI/CD) pipelines utilizing GitHub Actions, Docker, and Kubernetes. This
automation streamlined development processes, enforced best coding practices, and ensured
reliable deployment with minimal manual intervention.
Collectively, these advancements lay a solid foundation for future expansions of the PEAR
system, significantly enhancing its reliability, scalability, and maintainability.Bachelor's degre
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
