Projects on Going

1. Digital Archive Package Tools Research and Development Project

      Digital archive is a technology for a long-term preservation of digital content. There are several significant issues to consider in developing a digital archive: technologies and tools, scope, intellectual property, related standard, and partnership. In building the digital collections, we must make sure that the details represent both robust systems for today and archives for tomorrow. In this project, the outputs will be an answer to the question which means is appropriate to developing tool for creating digital archive that consistence properly to the target group. The tool is also easy to use and follow the same standard for the future information exchange. In the first phase, the project will be focused on developing a package open source tool for creating, managing, and publishing information for applications in history, arts, culture, and ancestor intellectual sectors.

2. Information Management System for the Victims from Disasters

     For the past few years, there were many catastrophe around the world. Help and support flow from everywhere. KEA/NECTEC, a team to implement the registration system for the Tsunami in the south of Thailand, year 2004), has been continued to do research and development of the ICT system to manage the post disaster events. In the first phase of the project, donation matching and missing persons tracing systems are implemented.
     There is a try to develop an ICT system to collect all donations of each disaster and to implement a matching algorithm between donations and victims requirements in the most suitable way. This proposed system consists of four modules: donations registration module, victims requirements registration module, a matching algorithm, and database management module. In the database preparation process, metadata standard for this matching system must be specified in XML format for exchanging data and information between related organizations' databases. The system is a web-based tool providing services via Internet allowing users and system administrators to access the database from everywhere in the world.
     From the past experiences in implementing the missing persons registration system for Tsunami victims, it has been summarized that there is no available ICT missing persons management systems in Thailand. The proposed system for managing the missing ones composes of three modules: missing persons registration module, missing persons tracing algorithm, and the DBMS module. XML is also applied for data and information exchange in this system. The proposed web-based service will be implemented to allow users to access the data of the system from anywhere in the country.

3. 3D Scanning Technology for SizeThailand Project

     Given the Thai Government’s selection of Fashion as one of its national priorities, and NECTEC’s mission to deploy state-of-the-art ICT, digital fashion is an ideal topic for KEA/NECTEC to pursue. SizeThailand is a project developed to apply the 3D body scanning together with the statistical data processing to produce Thai sizing standards. We plan to host body data on 12,500 subjects, implemented sophisticated size and shape tools. Provided services will be data hosting, data analysis tools, and customized measurement and shape analysis. With scanned body database, possible applications will be developed such as size recommendation, made to measure garments, and 3D garment try-on visualization. Prof. Philip Treleaven, a founder of SizeUK and an advisor of SizeUSA, is kindly give advises to SizeThailand project. Therefore, digital fashion is an ideal topic for KEA/NECTEC to pursue given the growing strength of the Thailand fashion industry, and the potential for offering digital fashion services via the Internet.


4. Gene Identification for Polygenic Disease Ressearch and Devlopment Project

     A polygenic disease means a disorder that is affected by many genes. Most of well known diseases in this class include autoimmune disease, heart disease, diabetes, obesity, autism, cancer and many others.
     In the post-genome era, the greatest challenge in the study of human-disease has been the understanding of causes underlying genetic disorders. For many complex disorders as mentioned above, the causes are known to be the defects of multiple genes or along with environmental factors to create a gradient of genetic susceptibility for the diseases. Traditionally, the genes can be tracked by using linkage analysis approach, which tests co-segregation within families of the disease trait through the generation. However, detecting the disease-susceptibility requires the identification and characterization of genes involved in polygenic disorders. This process is a difficult task due to a lot of independently contributing factors and the requirement of substantial resources, including very large collections of family data and highly informative genetic markers spanning the genome.

     We are conducting a computational approach to discover such the underlying genetic causes. Our approach utilizes high-throughput data along with the network of protein interactions and metabolic pathway information. This 3-year project aims to develop the efficient methods to elucidate a set of essential genes, which are responsible for a specific polygenic disease and of high medical importance.

5. Web Sites Development for Projects under Initiative of Her Royal Highness Princess Maha Chakri Sirindhorn

     The fast innovation and widely use of the Internet have made many organizations realize that how the Internet is important for public communication. As seen in many organizations, they have published their contents on the organization web site. The main problem of publishing information via the Internet is lacking of an easy to use tool for non-technical persons using for manage the contents. For example, the organizations that are working on the project under initiative of Her Royal Highness Princess Maha Chakri Sirindhorn want to publicize their contents via the Internet but they lacked the expertise on web application development. So the development and maintenance of web sites under the initiative of HRH Princess Maha Chakri Sirindhorn project was started by responsible for design and develop web sites, design and develop database system, and develop a web-based management tool. This tool will used by the organization or the project under the initiative of HRH Princess Maha Chakri Sirindhorn for creating, managing and publishing their contents via the internet.
