  • In this paper we propose four-dimensional (4D) operators, which can be used to deal with sequential changes of topological relationships between 4D moving objects and we call them 4D development operators. In contrast to the existing operators, we can apply the operators to real applications on 4D moving objects. We also propose a new approach to define them. The approach is based on a dimension-separated method, which considers x-y coordinates and z coordinates separately. In order to show the applicability of our operators we show the algorithms for the proposed operators and development graph between 4D moving objects.

  • Objectives: Hypertension is the highest ratio among chronic disease in Korea, and the western medical information about hypertension is provided by many web sites. Advanced researches about hypertension have been conducted in Traditional Korean Medicine(TKM) for decades, but the research results are not arranged. So the results have not been utilized in following research nor contributed to the expansion of public knowledge. Methods : We did this study to improve this situation. In this study, we built database about advanced research articles related hypertension in TKM and implemented TKM information system of hypertension. Results : First, we benchmarked hypertension information systems and designed the TKM information system based on the benchmarking results and comments from TKM doctors. And it was composed of introduce, treatment, and etc. Second, we built prescription, herb, acumoxa, qigong, prevention/management, and pill database which is about 600 data extracted from papers and books. Third, we implemented JAVA/JSP based web information system which provides the database. And we created links for the each papers and books to use more easily. Conclusions : If we provide the research results about TKM hypertension diagnosis and combinational medication of western and oriental medicine, this information system will be more useful. And if we add internal and external project report about hypertension, it will be more worthy.

  • In order to utilize the data obtained during the deep-sea resources exploration program, the analysis of data structure and database were conducted to develop an appropriate data operating system called Deep-sea Database System. The Relation Data Base Management System, RDBMS, was chosen as a data managing system and the MS Access$^{TM}$ as a DB engine, and the MapInfo$^{TM}$ software as GIS tools. Problems in networking and security were detected and solved during the operation test. Accordingly, development of standardized operative procedure was proposed in obtaining raw data. This proposal will also be reflected in the subsequent phase of the deep-sea program. The Deep-sea Database System could be applied to the selection of potential mining sites and the estimation of economical efficiency over th KODOS (Korea Deep Ocean Study) region. It is also expected that this system might improve the efficiency of detail survey and help in the relinquishment process as a fulfillment of the obligation as a pioneer investor.

  • There has been necessity to supplement the fin database to improve the accuracy of low-fidelity aerodynamic solver for missile configuration. In this study, fin database is expanded by in-house solver, utilized in the triservice data the previously established into regions beyond means of CFD. Fin alone data of CFD analysis results in the original region is matched well with triservice data originated from the wind tunnel tests. Extensive fin aerodynamic data from CFD analysis is added to the existing database of the low-fidelity solver. For confirmation, aerodynamic characteristics of body-tail and body-canard-tail missile configurations is computed using upgraded low-fidelity solver at transonic region. The result using improved solver shows good agreements with wind tunnel test and CFD analysis results, which implies that it becomes more accurate.

  • At present, more than 300 races of the Silkworm are conserved and used as valuable genetic resources. But because of the uneffectiveness of manual data management, faster and systematic data base construction is needed. So, development of silkworm genetic resources management program has been begun and the result can be practically used. When developing the program, Visual basic was used for data input system construction, and MS Access for database. IIS(Internet Information System) and ASP(Active Server Page) was also used for searching data and information with Internet Web Server and Web Browser which is comfortable for constructing database and providing information. Data input item consists of 46 practical characteristics such as race name, moltinism, larval period and pupation percentage etc.. And these characteristics are classified with qualitative and quantitative character. Photographs of silkworm, cocoon and other related items were scanned and the image data was recorded on the database.

  • In this paper, we compare several methods for implementing a VHDL design database through a case study on VHDL tool development system. We implemented three versions of the VHDL design database which the VHDL tool development system is based on. The first version was coded in the C programming language following value-oriented paradigm. The second one was coded in the C++ programming language following object-oriented paradigm. The third one was implemented using an existing object-oriented database. Based on our experience, we present quantitatively the pros and cons of each implementation method. The value-oriented version was most difficult to implement but showed good performance. Compared to the value- oriented version, the C++ version was twice as easy to implement and showed about the same performance. Using an existing object-oriented database allowed easiest implementation but resulted in a 1.5 to 6 times slower version.

  • 유아는 만3~5세 사이에 언어 능력이 빠르게 발달하게 된다. 유아의 언어발달에 맞는 다양한 경험을 위해서는 그 시기에 맞는 콘텐츠 개발이 필요하다. 다양한 콘텐츠 개발을 위해 유아에 맞는 음성 인터페이스를 이용하는 것이 필요하지만, 한국어에서는 유아를 대상으로 한 데이터베이스가 구축이 되지 않았다. 본 논문에서는 한국어에서 만 3~5세 유아들의 객관화되고 정확한 음성 데이터 수집을 설계하기 위하여 발달시기에 맞는 적절한 단어 선정 및 성인과 다른 유아의 행동 특성 유형을 파악하는 과정을 거쳐 음성 데이터 베이스를 구축하였다. 단어의 경우 MCDI-K에서 두 단계를 걸쳐 선정하였고, 유아는 한 단어 당 세 번씩 발성하였다. 이렇게 수집된 음성 데이터는 유아별, 단어별 파일 토큰화 과정을 거쳐 데이터베이스로 구축되었다. 한국어 유아 음성 데이터베이스는 웹 페이지를 통한 기술 이전을 할 계획이며, 이를 통하여 유아들의 언어 발달에 유익한 다양한 콘텐츠 개발에 그 익일을 담당할 것으로 기대한다.

  • The food composition database is used to evaluate the nutritional value of foods in Korea. It is used as a source for basic data in many fields, not only for the establishment of the National Food Supply Plan but also for nutritional research, to aid in the drafting of the National Food Policy, and in clinical and epidemiological research. The database is also used by institutional and commercial food services and by the food processing industry among others. In 1970, the Rural Development Administration(RDA) published the "Korean Food Composition Table" for the first time and it has since become the established authority on food composition for the entire nation. The latest published food composition table (the 6th edition, published by the National Rural Living Science Institute, KDA) covers 2,337 kinds of foods and consists of two volumes. The National Rural Living Science Institute, the Korea Food and Drug Administration, and the National Fisheries Research and Development Institute have continuously improved production of food composition data in Korea. As consumers have grown more interested in the quality and safety of foods and raw agricultural products, we can expect even further development of food composition data through improvements in quality and increases in quantity. We need to develop more comprehensive food composition data by diversifying the kinds of foods that are included, unifying analytical methods, and increasing the number of nutrients covered. Moreover, food composition data must be modified in other ways to make for a better food composition database for the convenience of users. of users.

  • This study presents the first analysis system and fast-access cloud database for shrinkage and creep of concrete in the world, named "shrinkage and creep database in Taiwan", SCDT. SCDT not only has the most comprehensive experimental data, including NU, JSCE, Europe, and TW databases, but provides a design tool for researchers and engineers. It can further facilitate the development of prediction models for localized concrete. Users can obtain the shrinkage and creep curves based on their selected prediction models in SCDT. Comparisons of the predicted results of selected models and test results in the chosen database can be generated in seconds. One example of the development of basic creep prediction model in Taiwan based on model B4 by using SCDT to reflect concrete characteristics in Taiwan is also presented in this study. Users anywhere in the world can easily access SCDT to browse and upload data, receive predictive results, or develop predictive models.
