The contemporary period is called "the age of sensibility" in which each individual consumer seeks to have her or his own products. Businesses are in need of design developments with an emphasis on customer sensitivity, and at the same time consumers must understand their own sensitivity to acquire information on designs that suit them. This research established a sensitivity and configuration database on designing men's jackets using the sensitivity engineering approach to clothing design information. The user interface was created on the Internet. Sixty-seven sensitivity terms of vocabulary appropriate for the assessment of men's jacket design were selected, and the different designs were classified into six items and 24 categories. Thirty men's jackets with different designs were produced for sensory testing and the results were analyzed in accordance with general linear I statistics. A sensitivity database was established for each category. My-sql, PHP, Java Script, and Html were used for the configuration database work. The configuration of items/categories, with the most appropriate sensitivity database information assigned to the selected sensitivity vocabulary, was programmed for display on the computer screen. The sensitivity vocabulary of a customer's choice for each factor was selected for the program to run, while the category and product configuration of the men's jacket most suitable for the search was displayed based on the user interface.

Collision accident reconstruction algorithm are developed based on the deformation shape and severity of a car body. At first, the body stiffness equation representing the force-deformation relationship is derived using finite element analysis for head on collision of two cars. The database of deformation shapes and energies is constructed for five different collision configurations; each configuration contains three velocity conditions. Deformation shapes are obtained using a curve fitting method and result in cubic polynomials. Deformation energies are calculated using a stiffness equation and deformation data. Three algorithms are developed to reconstruct collision configuration compared with constructed database. The developed algorithms show reasonably good performance to find collisions conditions for some test problems.

원자력발전소는 총 사업비 약8.6조, 사업기간 10년 이상이 소요되는 대형 국가기반사업이며, 60년 이상 운영되는 국가경제 및 국민의 안전과 밀접한 시설이다. 따라서 설계, 건설, 운영 등 프로젝트 일련의 과정에서 정확하고 경제적 의사결정이 가능하도록 정확한 정보와 일관된 물리적 형상이 유지되어야 한다. 하지만 원전산업은 다른 산업에 비해 복잡하고 규제가 많아 일찌감치 형상관리의 중요성이 널리 인식되어왔지만, 목적과 주체가 명확하지 않아 체계적인 형상관리에 한계가 있었다. 따라서 본 논문은 많은 격실로 이루어진 APR1400을 설계요건과 형상정보를 반영한 실(Room)기반 데이터베이스 구축 방안을 제시하였다. 실 속성을 구분하는 4가지 요소를 선정하였으며, 이를 기반으로 한 데이터베이스를 활용하여 완성도 높고 체계적인 원자력발전소의 형상관리 체계 활용에 일조하고자 한다.

Generally, the internet online game systems are divided into two parts, clients and servers. The clients provide a connection with game server to each user and communicate between them. And, the server controls all clients by the game rules fairly and manages database systems to maintain the user information. In this paper, we propose a configuration method for internet online game servers using distributed scheme. To apply this method, we divide game server into three sub-level parts again. First part of game server is login server to establish the connection between communication server and clients. Second part is communication server to connect between clients and main game server during playing the game. And last part is DBMS that performs database independently. Our proposed scheme suggests that the game server operates very stable because of decreasing of processing load by distributed scheme. So, our proposed server configuration applies to similar online game easily.

There are many technical datum in related with design, test & evaluation and logistic support which will be exchanged between geographically isolated units and heterogeneous hardwares & softwares in developing and operating the weapon systems. The paper proposes the conceptual database schema to establish configuration management information systems in which these datum can be automatically interchanged, tracked, audited and status-accounted without errors under the various environments. The paper investigates how to identify and classify the data in accordance with document identification, task analysis, system development, logistic support, system test & evaluation and data management. Furthermore, the investigation includes drawing the subject areas and modeling the conceptual database schema to explain the relationships between these datum. Thus, the paper results in the conceptual framework and data models of configuration management information systems, while additional customization efforts be required in applying the models to a specific weapon systems R&D.

A study of the conceptual data modeling to realize the decommissioning database on the HRR-1&2 was carried out. In this study, the current state of the abroad decommissioning database was investigated to make a reference of the database. A scope of the construction of decommissioning database has been set up based on user requirements. Then, a theory of the database construction was established and a scheme on the decommissioning information was classified . The facility information, work information, radioactive waste information, and radiological information dealing with the decommissioning database were extracted through interviews with an expert group and also decided upon the system configuration of the decommissioning database. A code which is composed of 17 bit was produced considering the construction, scheme and information. The results of the conceptual data modeling and the classification scheme will be used as basic data to create a prototype design of the decommissioning database.

Star 형상을 갖는 추진제 그레인은 다양한 면적 선도가 가능하고, 제작이 용이하여 실제 고체 추진제 로켓에 유용하게 적용될 수 있다. 그러나, 설계와 관련한 형상 변수가 많고 연소 말기 슬리버가 존재하므로, 해석 비용이 저렴한 일반적인 단일 최적화 기법으로는 최적 설계가 성공하기 어렵다. 본 연구에서는 활용성과 설계 성공률을 높이기 위해 데이터베이스를 사용하여 star 그레인을 설계하는 기법을 제안하였다. 제안된 방법에서는 성능 변수를 정의하고, 데이터베이스를 구축한 후 요구조건을 만족하는 해를 탐색한다. 제안된 방법을 적용하여 다양한 종류의 연소 면적 선도를 갖는 star 그레인의 설계를 수행하고, 설계 방법의 타당성을 검증하였다.

As database become more variable and multimedia, the integration between conventional library based on printed matter and digital library on IT makes it accelerated that the changes in today's information circumstances. Due to more leisure time modern people who get intellectual and interested in variety so they need continuing education, intellectual satisfaction and cultural life. Consequently today's public library expands to become a source of every kind of information, an educational facility and community facility to fulfill the cultural needs. On the assumption above, this study aims at offering database for planning public library that meets the needs for multifunctional library through analyzing space, structure, and character of modern public libraries and chooses 8 cases in Japan provide both primary and additional functions. Quantitative data from blueprints, websites and publications has been collected to analyze the space arrangement corresponding with the functional characteristics.

The livestock manure recycling have been performed worldwide because of its environmental and economic benefits. However, domestic standard protocol was nothing for high solid manure. Therefore, This paper was conducted to review database configuration of manure characteristics, analysis methods, bio-methane potential test for high solid manure recycling. In American society of agricultural engineers standard, manure characteristics indicated about sort of thirty types. This is important information to determine for manure recycling method. Furthermore, in order to determine exact manure characteristics recommended that synchronized chemical analysis method among studies. Bio-methane potential tests are widely performed in studies about estimation of organic substrates methane production. Although various methods and parameters were used, was no standard protocol and guideline in domestic. Bio-methane potential test methods and parameters were reviewed through various researches. Consequently, this paper is expected that assist to additional studies and manure characteristic database.
