This study was initiated to build runoff plots, install soil and water quality monitoring systems and collect background data from the plots and neighboring soils as the 1st year study of a 5 year project to assess soil quality and develop the management practices for environmentally sound agriculture in mountainous soils. Eleven $3{\times}15m$ runoff plots and monitoring systems were installed at a field of National Alpine Agricultural Experiment Station to monitor soil quality and discharge of nonpoint source pollutants. Corn and potato were cultivated under different fertilizer, tillage and residue cover treatments. The soil has a single-layered cluster structure that has a relatively good hydrologic properties and can adsorb a large amount of nutrient. Concentrations of T-N, $NH_4$-N, and $NO_3$-N of surface soil sampled in the winter were relatively high. Runoff quality in the winter and thawing season in the spring was largely dependent on surface freezing, snow accumulation, temperature, surface thawing depth and so on. Runoff during the thawing season caused serious soil erosion but runoff quality during the winter was relatively good. Serious wind erosion from unprotected fields after the fall harvest were obserbed and best management practices to reduce the erosion need to be developed.

As control of plant diseases, insects and weeds were heavily relied on pesticides, residues of pesticides in environment and food supply were recently focused by environmentalists and consumer groups. The reduction of pesticide use was implemented in Sweden, Denmark, Netherland, England, and United States. Therefore, it is very important to discuss environmentally sound systems of weed management including cultural, mechanical, and integrated weed control. Mechanical methods using tillage, cultivation, mulching, burning, mowing, solarization, and UHF are used as one of most effective environmentally sound weed management systems. Cultural practices favoring the crops are excellent weed management measures. Correct seedbed preparation for the soil and cultural system, and use competitive cultivars contribute to weed management. Increasing crop density by higher seeding rate or by narrowing row width and careful attention to optimum fertility to produce vigorous crop plants increase competitiveness of crops against weeds. Crop rotation breaks life cycles of weeds by alternating the crop it must associate with. Herbicides are efficient and profitable to control weeds, but must be part of a total weed management program with use of minimum rate. The best weed management will be an integrated approach including two or more methods to manage weed problems.

In agricultural ecosystem, soils which play important roles of storage and cycling of substances become a crtitical social problem due to rapid increase of contaminants with respect to our health. Soil as productivity should be interpreted as soil quality, that is important criteria in maintaining sustainable agriculture for production of safe food. Therefore, it needs to set the criteria of soil quality by considering environmental factors including relevant parameters which are involved in soil quality soil health because soils are widely distributed and have various characteristics such as physical, chemical, and biological propevties. Therefore, it requires intensive investigation of evaluation methods and development of related parameters for environmentally sound agriculture and safe soil management.

The duck-rice forming system is increasingly spread up throughout Korea since 1992. It is discussed the rice field, rice quality, weed and pest management in the duck-rice weeding system compared to conventional farming system. Moreover the optimizing duck population, system management and fertilizer application rate were reported. Energy input and output by duck-rice farming system were carefully compared with those of low input sustainable paddy field and conventional farming paddy field. To find out the environmentally sound function of duck-rice system, the total nitrogen in paddy soil and paddy water, and nitrogen cycle in paddy rice cultivation system were analysed. finally the input and output were calculated, and ecological characteristic were determined in terms of nitrogen balance, labor input, animal input, renewable energy input, turnover of soil organic matter, energy loss, non-renewable indirect and direct energy input. It was concluded duck-rice weeding system could be recommended in terms of net only environmentally sound, but also farmer's income. But there are still some research needs for successful adaption of duck-rice farming to investigate to determine the optimal population of duck in rice paddy field unit, release time of duckling, duck management after release, and strategy for duck marketing and duck processing.

The purpose of this study was to analyze the preference of living room furniture and to suggest Korean brand furniture design guideline. Subjects consisted of 171 residents aged up 20 years old in Seoul and Kyung-ki. area. The data were analyzed using the SPSS statistical package. The results of descriptive statistics, factor analysis, t-test and $x^2$-test are presented. The result of this study showed as fallows; 1) Livingroom funiture design with considering family life behavior were needed. 2) Modernizing traditional elements(motives and pattern) were preferred to duplicating traditional elements. 3) In furniture materials, easy to maintaining and cleaning and environmentally-sound materials as solid wood were highly appraised. Also, functional and harmonious furniture design with interior or other furniture were needed. So, modular-system furniture for livingroom would fulfill user's needs which are function, harmony and conciseness. 4) Elegant, easy, unique, functional, and simple design for livingroom were highly appraised. Considering these results, it is necessary to develop more on the modernized traditional furniture based on the various needs of users. These results provide a practical guideline for the development of the Korean brand design for livingroom furniture design.

Recently, CO2 reduction policies are being promoted as parts of ESSD(Environmentally Sound and Sustainable Development), and many local governments are interested in monorails as a new means of transport. Here we report on a feasibility study for introducing a monorail system by considering the travel demands in the Mt. Bomun area in Daejeon, based on the area's population. The feasibility of a monorail system on Mt.Bomun varies with respect to the demographic scale, mode shares, and operational distances. The strategies introduced here will help identify any tourist spots where local governments are trying to introduce monorail systems as a new system of transit.

The built environment of the elementary school influences on the character and the social skill of children in that childhood development stage. In this regard, sound environment in the elementary school is also important as the other environmental factors. Soundscape design is a design attitude for a better sound environment what landscape design targets a visual one. Four soundscape factors in elementary schools are extracted in this study from surveys on existing elementary schools. They are abstracted and characterized to related design patterns which denote the intended sound environments. The design patterns can be converted into design ideas and applied to an actual design project. There are possible advantages in the proposed elementary school design, environmentally and educationally, especially with the 'designed' soundscape.
