Today, GIS service requires not only a simple map visualization but also geographical information of each object. However, POI service provides simply geographical naming service only because of lacking in geographical information of objects. In addition, geographical space data representation functioning that is the basis for most GIS has not been standardized yet. In this paper, it is designed that POI DB that is hierarchical and user-oriented and it is constructed that GVP(GML Viewer POI) that is the basis of GML specification to overcome difference and incompatibility of map visualization. GVP adds POI DB in a 3-Layer structure to dBase file managing the information of SHP file attributes. Therefore, POI visualization enables hierarchical search, by providing POI information in directory-type grouping. Consisting of map visualization and POI visualization, GVP regenerates attributes in the form of individual objects and responds to user events immediately.

Each country uses its own datum which well represent its topography. The uses of the space technology such as GPS and the effort of establishing the consistent data over the world, Korea changed the survey act to use a world geodetic system from January 1, 2007. In this study, spatial analysis carried out to transform the GIS DB of electric power distribution system based on the old Tokyo datum the new world geodetic system, KGD 2002. Based on the study, problems on the transformation had been identified and efficient solutions are suggested. The data used for the 7 parameter similarity transformation in this study is the blueprints of the electric equipment and base maps. It is expected that this study provide general scheme and procedure for efficient GIS DB transformation to the new world geodetic system.

In this paper, 4 representative soft clayey soils in south Korea are selected to estimate the geotechnical characteristics and provide the instructions avaliable for construction works; Inchon Coast, Kum River Estuary, Kwangyang Bay, and Nakdong River Estuary. Total 2250 boring data are collected to construct the data base system on selected areas from Korea geotech DB system, scientific journals, theses, and site investigation reports. Considering the geological, topographical and regional features, geotechnical properties, deformation and strength characteristics of 4 soft clayey soils are evaluated by analyzing the constructed DB system statistically.

In the past, the important factors of buying the sports shoes for the customers were price and comfort. However these days, the sports shoes are considered as a part of fashion and may not satisfy the customers because their emotional preference have not been properly considered in design phase. The customers' desire and expectation for unique design are growing. Thus, the development of sports shoes not only considering the anthropometric foot characteristics but also satisfying the customers emotional preference is needed. In this study, the basic data on the customer's emotional preference to the design of sports shoes were obtained using human sensibility ergonomics approach and formed a data base. Also, we developed ail interface that can be used for the customers to select the emotionally preferred sports shoes.

Purpose of this research is that offers basic data for optimized design using neural network method to calculate consolidation settlement in study area. In this research, preformed the neural network method that analyzed the settlement characteristics of soft ground nearby study area. Thus, data base established on ground properties and consolidation settlement of neighboring area. In addition, designed the optimum neural network model for prediction of settlement through network learning and consolidation settlement prediction using consolidation settlement DB and ground properties DB. Optimized neural network model decided by repeated learning for various case of hidden layers. In this study, proposed that the optimized consolidation settlement calculation method using neural network and verified which is the optimized consolidation settlement calculation method using neural network.

The number of people with a disability registered in the Korea's Ministry of Health and Welfare is more than 2.5 million in 2010, and approximately 2.51 million as of late 2012. In consideration of potential disabilities led by aging which is in fast progress in Korea, the number of people with a disability will further increase. It is necessary to study the method of enabling people with a disability to easily access facilities and of using facilities for people with a disability, in order to comply with the Disability Discrimination Act (DDA) which is enforced in Korea. In this study, a smartphone recently used more and more is used to develop a smartphone which can recognize locations, voice and the QR code for enabling people with a disability to recognize them. The developed smartphone for people with a disability is connected to a database established as a facility for people with a disability, and to the navigation system in the wheelchair accessible call taxis, to enable the disability database to be used. This study will contribute to observing the Disability Discrimination Act of Korea, and improving the national welfare system by enhancing the disability care services.

Wireless sensor network forms the self-organization network, and transfers the information among sensor nodes that have computing technology ability and wireless communication ability. The recent sensor network is study for low-power, micro, low cost of node is proceeded. Recently, the research of application services in wireless sensor networks is proceeded. Therefore, in this paper, we design the prototype of the real-time information service that support a user the information of temperature, illumination etc. And, we implement the alarm application service fer the disaster prevention on Internet base on IPv4/IPv6. We develop the module of the extract information using the query processing based on TinyOS, and the module of the server's database using MySQL data base management system and JDBC. Additionally, we develop the client module that receive the real-time sensing data using ODBC in Internet based on IPv4/IPv6.

데이터 마이닝란 대량의 실제 데이터에서 묵시적이고 잠재적으로 유용한 정보를 추출하는 작업이다. 본 논문에서 서로 관계가 정의되지 않은 데이터베이스의 각 테이블간에서 필요한 정보를 추출 또는 가공하기 위해 데이터 마이닝 기법을 사용한다. 마이닝 기법인 연관 규칙은 어떤 사건이 일어나면 다른 사건이 일어나는 관련성을 의미하는 것이고, 제시된 규칙 기반의 데이터 마이닝 기법은 연관 규칙의 한 분야로서 데이터를 규칙 맞게 분류하는 기법이다. 이런 마이닝 기법을 구현하기 위해 인공지능 분야의 규칙 기반의 전문가 시스템을 사용하였고, 실 시스템인 GDS(Grating automatic Drawing System)에 적용하였다.
