Since the introduction of 'the rule for computerizing subsoil investigation results and its application' in 2007, the DB construction of the national geotechnical information by Ministry of Land, Transport and Maritime Affairs (MOLTMA) has been performed. According to the Integrated DB Center of National Geotechnical Information, there have been 180 thousands borehole information stored in the system. In this study, the time-series analyses of precision on the most used information, the depth of stratum and ground water level, were performed to evaluate the effect of the initiation of the rule established in 2007. The precisions were evaluated based on the statistical analyses using kurtosis and normal distribution. Based on the results, the increase of precision after 2007 and the affirmative effects of the rule established in 2007 are confirmed. Furthermore, the precision of the regional information can be achieved with the precision analyses on the information from various areas.

It is important to verify the validity of indicators assessing PMIS(Public Management Information System) effectiveness in academic research as well as practical affairs. As people invest in the field of Information Technology(IT) or IT system, private corporations are interested in investment in IT and it's business value. Moreover, the need of evaluating effectiveness on the investment in IT with the limited national budget are on the increase in public sector. Therefore, it is necessary to define the construct of PMIS(Public Management Information System) effectiveness so that we systematically compare and measure performance of public informatization project processed by each public organizations. It needs to develop indicators and verify the construct validity of them. we verified the construct validity of indicators assessing PMIS(Public Management Information System) effectiveness on the Administration DB Construction Projects.

Over the past decade, changes in product development processes and increased consumer demands have dramatically influenced engineering working practices and targets. The information technology revolution has made its appearance concurrent to this relentless escalation in product engineering requirement. It has offered hopes for improved productivity despite these increasing demands. The wide availability of personal computing power, virtually inexhaustible sources of information and an abundance of computerized engineering tools have created great expectations. Knowledge information modeling system and database were developed using ASP and Microsoft SQL 2000 Server to share the DB that can be utilized to process on the web.

Material selection is one of the important activities in design and manufacturing. A selected material at the conceptual design stage affects material properties of the designed part as well as manufacturability and cost of the final product. Unfortunately there are not many accessible material databases that can be used for design. In this research, a web-based material database was constructed. In order to assist designers to compare different materials, two-dimensional and three-dimensional graphs were provided. Using these graphical tools, multi-dimensional comparison was available in more intuitive manner. To provide environmental safety of materials, the database included National Fire Protection Association publication Standard No.704. The web-based tool is available at http://fab.snu.ac.kr/matdb.

급격한 도시화로 인하여 도시기반시설의 필요성에 의해 도시계획시설들이 많이 결정되었다. 헌법재판소는 도시계획시설의 지정으로 인한, 토지소유자의 토지 사적 이용권의 배제에 대해 헌법 불합치 판정을 내렸고, 2000년 1월 28일 도시계획법의 개정이 이루어짐으로써, 기존의 미집행 시설로 인한 사유권의 침해는 시급하게 해결되어야 할 과제로 발전하게 되었다. 이에 따라 장기미집행 도시계획시설에 대한 전면적인 재검토 및 재정비 계획을 수립하게 되었다. 이를 위해 본 연구에서는 GIS 분석기법을 이용하여 미집행 도시계획시설의 데이터베이스를 구축하였으며, 향후 LMIS의 지리정보 전산화일과, UPIS의 도시계획시설 데이터, 조서 자료 및 고시자료 등을 이용하여 미집행 도시계획시설 관리를 위한 기본 DB를 구축하고자 한다.

Since standardization project is composed of complicate system, such as vehicle, signal, electric power and railway, how to build management system of the project has influence on the success of the project for the first stage of the project. The computer system design tool supports to carry out requirement analysis, DB construction, and history and follow-up management efficiently. Therefore, the aim of this study is to investigate the method to optimize schema using computer system design tool.

This paper developed the computerizing assessment system modeling of the natural gas and district heating DSM programs. It constructed as each project in accordance with the business investment plans & assessment DB, related M&V data DB and cost-effectiveness analysis data DB. It is composed of total 58 tables which are 22 tables which are used in the plan and the assessment, 16 tables which are used in the cost-effectiveness analysis, 18 tables which are used in the M&V, table which is used in qualitative evaluation, as by each programs. This computer programs can contributed to DSM business investment system construction as implementing for algorithm development and an estimation by each programs.

Leading of the computer, IT technology has make great strides. As a information-industry-community was highly developed, user's needs to convenience about intelligence and humanization of interface is being increase today. Nowadays, researches with are related to BCI are progress put the application-technology development first in importance eliminating research about fountainhead technology with DB construction. These problems are due to a BCI-related research studies have not overcome the initial level, and not toward a systematic study. Brain wave are collected from subjects is a signal that the signal is appropriate and necessary in the experiment is difficult to distinguish. In addition, brain wave that it's not necessary to collect the experiment, serious eyes flicker, facial and body movements of an EMG and electrodes attached to the state, noise, vibration, etc. It is hard to collect accurate brain wave was caused by mixing disturbance wave in experiment on the environment. This movement, and the experiment of subject impact on the environment due to the mixing disturbance wave can cause that lowering cognitive and decline of efficiency when embodied BCI system. Therefore, in this paper, we propose an accurate and efficient brain-wave DB building system that more exactness and cognitive basis studies when embodied BCI system with brain-wave. For the minimize about brain wave DB with mixing disturbance, we propose a DB building method using an automatic control and prevent unnecessary action, put to use the subjects face tracking.
