In this paper, we have studied the expected problems when tunnel is excavated under the wetland, and described the measure to maintain the wetland's ecosystem environment. Firstly, we investigated the wetland's ecosystem such as plants and animals, and executed ground investigation including in-situ tests and geophysical survey. And we analyzed the foreign similar cases for tunnel excavation near the wetland. We also evaluated the runoff and infiltration quantity of groundwater and hydraulic behaviour of rock mass and wetland by numerical analysis. Finally, we established the effective measure to minimize the ecosystem's influence by tunnel excavation.

Based on the survey on abalone aquaculture management status in Nohwa-eup, Bogil-myeon, and Wando-eup in Wando region, this study compared the analyzed business performance generated from production by region. The results show that the abalone production quantity has been stabilized currently after rapid growth during the past 10 years. In the future, it will be the time for more positively spontaneous efforts by people in aquaculture business to restore fishing ground, in which they have actively and continuously worked, by means of clean-up of fishing ground, movement of fishing ground, or time-off period rather than just to focus on the short-term increase of production in all of three regions.

Recently, the whole world is concerned about the saving energy and protective environment, so interest is increasing in new and renewable energy. Specially the Bioenergy continuity is possible, the research is advanced by the energy which it contributes in environmental conservation. From the research which it sees consequently it investigates about co-generation system of domestic bio-energy, it is used to analyze the electricity and heat energy of buildings that Energy Consumption Survey of Korea Energy Management Corporation and food waste generation quantity of Ministry of Environment. This paper is analyzed that application of food waste Biogas plant system.

The objectives of this study were to survey stress, eating behavior, and the influences of stress on eating behavior of high school boys and girls. The subjects of this study were 510 high school students(boys 240, girls 270) in Cheongju area. The questionaires were distributed to 510 students, self-evaluated and collected from Mar. 23 to Apr. 4, 1998. The results of this study were as follows： First, the third grade students of high school were suffering from many stress. The rate of such students was 33.9% of total students. Second, eating problems of students were unbalanced diet, irregular diet, omitting a meal. The most irregular meal was breakfast, especially girl students ate breakfast more irregular than boy students. Third, the higher the level of stress of stress of the students, the more eating problem existed. The more students met with stress, the more eating behavior was irregular in eating quantity. In conclusion, stress influences eating behavior of high school students negatively. Therefore, to improve eating behavior of students who are suffering from stress, the program on stress release and nutrition education should be developed and supplied to them.

To Know the factors required to make best quality of steamed rice with large amount of rice, several organizations that serve meals were surveyed. Factor that mostly influence the amount of water to the amount of rice is a kind or rice. In the case of good quality rice, when the amount of rice is more than 10cups, the ratio of water to rice is 0.9 and that of poor quality rice is 0.7 Average ratio is 0.8 Therefore, ordinarily with the ratio of 0.8, good quality of steamed rice can be made. Washed rice should be used to measured the of rice. To make a good quality of steamed rice with large amount of rice, center part of the boiling rice should be stirred generously several times to equalize the temperature.

This paper considers Wedding Furniture(new furniture that brides prepare for marriage) design in Korea. Social survey research methods were applied to study wedding furniture from 1960 to 1990. A questionnaires were delivered to 766 urban housewives. As to the statistical methods of the study, descriptive analysis for frequencies, and $X^2-test$ were selectively performed using SPSS PC+ program. the findings are as follows; During this period, Wedding Furniture became an essential Honsu(혼수: wedding gift) item People choose as Wedding Furnitures that serve basic functions of furniture and are traditionally symbols of wedding. They were increased both quantity and quality. Typical Wedding Furnitures of the Modern time were Jangrong(장농: wardrobe for storing clothes and bed clothes), dressing table, wardrobe chest, cupboard and bed. Wedding Furniture items have become more various in kind. Criteria for selecting Wedding Furniture were functionality, affordability, fashion, and decorativeness, tradition and symbolic of marriage. but, The symbolic importance of Wedding Furniture as Honsu will be weakened with the introduction of a variety of electronic appliances.

This paper examines to focus on General Strategy of e-logistics activity for SCM(Supply Chain Management) Build-up, especially the field service logistics Integration. And this research analyzes the case study (Business of Strategy Group Unit) Survey) involving effective logistics management that leads customer satisfaction, seeking to find out the key elements of competitive policy. Because problems arise from the differences between their goals and structures, which cause each sied to feel vulneralbe to opportunism or shirking of responsibilities by the other. The goal of a logistics system is to ensure that every family planning client always receives the contraceptives partner wants, and that they are in good condition and have not expired. In order to select, procure, and distribute the right Quantities of the right contraceptives, managers of the logistics system must keep informed of the rates of use of each contraceptive and of the Quantity of available supplies. As a result, We propose that a firm's e-logistics strategy is an important locus innovation and a crucial source of value creation for the firm its suppliers, partners, and customers.

In this study, the Ground Penetrating Radar(GPR) was tested to evaluate the condition of concrete decks. Test results obtained by CPR were compared with values measured from drilled cores and damage mapping by the visual survey. It is shown that GPR can provide highly accurate measurements of layer properties of concrete decks and can map areas of deterioration in bridge decks by dielectric constants. The deck condition can be grouped into categories of "good" or "distressed". The ground penetrating radar data shows promise for producing rapid and accurate condition assessment for bridge decks. And these data can be used to evaluate highway bridge condition and make cost-effective bridge deck rehabilitation by accurately estimating the quantity of deteriorated concrete.

The process of determining whether, when, where and how to intervene, of deciding on optimum allocation of resources and minimizing the cost is a very complex problem: different track sections tend to behave differently under the effects of loading; decision-making processes for maintenance work are closely interrelated technically and economically; decision-making for maintenance plans is based on a large quantity of technical and economic information, extensive knowledge and above all experience. For that reason, It is considered very important to develope objective and computer-aided decision-making support system for track maintenance plan. On this paper, we made a survey of the state-of-art of decision-making support systems for track maintenance which were developed and used abroad and reviewed requirements of system and present the plan of develope decision-making support system for track maintenance appropriate to local condition.
