A prototype GIS-based decision support system (DSS) was developed by using a database management system (DBMS), a model management system (MMS), a knowledge-based system (KBS), a graphical user interface (GUI), and a geographical information system (GIS). The method of selecting a dispersion model or a modeling scheme, originally devised by Park and Seok, was developed using our GIS-based DSS. The performances of candidate models or modeling schemes were evaluated by using a single index(statistical score) derived by applying fuzzy inference to statistical measures between the measured and predicted concentrations. The fumigation dispersion model performed better than the models such as industrial source complex short term model(ISCST) and atmospheric dispersion model system(ADMS) for the prediction of the ground level $SO_2$ (1 hr) concentration in a coastal area. However, its coincidence level between actual and calculated values was poor. The neural network models were found to improve the accuracy of predicted ground level $SO_2$ concentration significantly, compared to the fumigation models. The GIS-based DSS may serve as a useful tool for selecting the best prediction model, even for complex terrains.

This study has investigated the perception of adults in relation to healthy family to help identify import issues. Gathered information were then incorporated to education programs for the Healthy Family Support Center. For this purpose, a survey was conducted in four cities in Kyungnam during March 2007. The responses of 213subjects have been used for the final analysis. The results of this analysis lead to three major findings. Firstly, the surveyed adults regarded positive interaction and domestic family functions as essential activities in healthy families. Secondly, the participants exhibited a very low knowledge-level of the 'Healthy Family Act', and the Healthy Family Support Center. Finally, the respondents said that they are more likely to specifically participate in educational program and counseling program if it helps them prevent family programs.

In this study, the indirect estimation method of the support load which is based upon the integrated measuring technique suggested by Kovari was applied to the calculation of support load in the mine roadway. Four test supports were installed in the area where they had to be replaed. Two of those were GI-130 rigid supports and the others were U-26 yieldable supports. The vibrating wire strain gages which were attached inpairs on the steel arch support were used to provide an accurate measurement. Bending moments and normal forces obtained from strain gage pairs were used to calculate the support load. This method was also verified by laboratory bending tests. The results obtained from the back-calculction method showed relatively good agreement with the measured convergence for each crossection.

Recently, we have witnessed a host of emerging tools in the management support systems (MSS) area including the data warehouse/multidimensinal databases (MDDB), data mining, on-line analytical processing (OLAP), intelligent agents, World Wide Web(WWW) technologies, the Internet, and corporate intranets. These tools are reshaping MSS developments in organizations. This article reviews a set of emerging data management technologies in the knowledge discovery in databases(KDD) process and analyzes their implications for decision support. Furthermore, today's MSS are equipped with a plethora of AI techniques (artifical neural networks, and genetic algorithms, etc) fuzzy sets, modeling by example , geographical information system(GIS), logic modeling, and visual interactive modeling (VIM) , All these developments suggest that we are shifting the corporate decision making paradigm form information-driven decision making in the1980s to knowledge-driven decision making in the 1990s.

In high-speed line, at some part of the track which rubber ballast-mat installed, track irregularity grew rapidly and affected riding comfort and train running stability. It is urgently requested to establish counter-measures which can be applied to track under operation. To do this, it is very important to analysis the origin of that phenomenon before. Track support stiffness is an essential factor for evaluating track condition. Sudden changes of support stiffness along track occur instability of train and bad riding comfort. Preventing sudden changes of track support stiffness is a key technique in high-speed track maintenance. Besides the sudden changes, the magnitude itself also significantly affects track and train. Low stiffness of ballast-mat makes ballast acceleration area wider. And it may accelerate track irregularity growth. So, the stiffness should be limited. To calculate track stiffness, measuring load and displacement on track is needed. In this study, the behavior of the track which rubber ballast-mat installed was measured and analyzed to understand the origin of rapid growth of it.

Opening agricultural market expansion, reduced purchases through wholesale markets, expanding the influence large retailers of consumer's market such as changes in the distribution system to the farmer's market conditions are changing rapidly. Because of this, retailers of the scaled and chain-store operations was centered on distribution environmental changes of the consumer market place. In producing area due to changes in market conditions in the agricultural production of in producing area distribution organization and the size distribution can not be put off no longer challenge is imminent. If it do not raise forces banded together, the producer is bound to remain as the weak. To support the distribution of this production was introduced in 2000 enable the Activation Project of in producing area distribution. Recent in producing area Changes of Agricultural conditions in order to cope with the Small-scale farmers and small individual farmers are becoming Scaled and specialized. Also, is specific to each item and regional is showing aspects. Government support for Activation Project of in producing area distribution is greatly improved, but in terms of competitiveness on the market still is showing the limitations. The most common of these problems, the market response if in producing area producer's organization and scale of the problem. Equipped for the purpose of consumer market place responsiveness unreasonable propelled outward from the Painter-sized weakens the organizational power. also, Difficult to succeed organizational size is a dissolution or anything within a few years, farmers around the best producer organizations, such as deviation occurs is exposed to a variety of issues.

This study was conducted to identify the social support to living alone elderly in some rural communities and the level of life satisfaction. For the purpose of this study, face-to-face interviews and questionnaire were performed with 315 old people(male 43 and female 272) aged over 65 living alone in rural communities covered by 14 community health posts within Gyeongsangbuk-do Province randomly selected. The followings are summaries of findings; The average score of support from their children was $4.29{\pm}2.73$ out of 8. Variables that showed a significant difference were religion, level of living, type of medical insurance, frequency of meeting with children, time taken from houses of children by usual means of transportation, and subjective health status. It was found that the score of support from children was high for the elderly who had a religion, a good level of living, benefit from medical insurance, a high frequency of meeting with children, or a good subjective health status, or who resided close to their children's houses. The level of the support from friends and relatives showed a significant difference depending on the subjective health status, of which the average score was $4.13{\pm}2.61$ out of 8. The average score of the level of life satisfaction was $6.83{\pm}4.24$(male $7.60{\pm}4.09$ and female $6.71{\pm}4.26$) out of 17. Male elderly showed the higher level of life satisfaction than female elderly. Variables that showed a statistically significant difference in the level of life satisfaction were religion, level of living, medical insurance, hobby, children, disease, subjective health status, and ADL. That is, the level of satisfaction with life was found to be higher for the elderly who had a religion, a good level of living, benefit from medical insurance, a hobby, children, no diseases, or a good ADL, or who thought that they are healthy. The regression analysis with support from children as a dependent variable showed that the level of support from children was higher for the elderly who had a good level of living, frequency of meeting with children, or a good subjective health status. The regression analysis with the level of support from friends or relatives was higher for old people who had a good level of living. The regression analysis with the level of life satisfaction as a dependent variable showed that the factors which related to the level of satisfaction were sex, religion, level of living, hobby, ADL, and subjective health status. That is, it was found that for male elderly who had a religion, a good level of living or a hobby, or who thought that they were healthy, the level of life satisfaction was higher.
