This study was focused on the system of regional resource circulation(RRC) of Asan-Si as a case region. So 301 farmers(members of producer organization) who are managing environmental-friendly agriculture (EFA) are surveyed. The RRC system is focused on establishing the system of regional complex farming connected with the seedling fanning and the livestock. The main results surveyed are as follows : First, total cultivated acreage is 574ha. Second, the total quantity of by-products of rices, beans, wheats is 983M/T. Third, the total quantity of nutrient requirement for seeding fanning is 85,335.6kg This research shows how to develop the RRC system for EFA. The development model and strategies are as follows : The first model for the system of regional resource circulation can be called the scenario of the best output for the system of environmentally friendly resource circulation. It is considered to estimate the appropriate number of heads of Korean cattle and hen which can be bred simultaneously. And the second model can be called the scenario of the regional allotment for the appropriate number of heads of those. It is considered to estimate the appropriate number of heads of those which can be alloted by the individual farm or area.

The statistical analyzing of environmental-friendly planning elements is getting important because it is getting concerned with the change of residential types and environmental friendly housing. However, in terms of the high-rise residential complex, paper about green building rating system and research about residential satisfaction to residents are lack. Therefore, this paper is analyzing of impotentness and satisfaction about housing subdivision, inside of building, facility, and maintenance. In addition, residential satisfaction(satisfaction, loyalty, preference) and impact relationship of environmental-friendly planning elements are analyzed by PLS structural equation. To sum up, first, improving of green building rating system in housing subdivision is impacted on loyalty if satisfaction was fulfilled. Second, increasing of environmental-friendly planning elements in inside of building is impacted on loyalty if both satisfaction and preference were fulfilled. Third, providing of green building rating system in facility and maintenance is analyzed as preference, but satisfaction hypotheses is not valued.

This study was intended to examine the change in the perception of the professionals for the environment-friendly apartments. After result of implementing the question survey against the professionals two times, the degree of importance in the environment-friendly design elements didn't show any significant change. However, it showed the degree of maturity on the concept of environment-friendly development is widely spreaded in terms of social, economic and environmental aspects. Based on the description of such results, the conclusion can be deduced as follow; 1) Presumably it would require 5 years for the diffusion of the concept of environment-friendly apartments and 10 years for the construction of developing its materialization and settlement respectively, 2) The proper density would be designed in $150{\sim}200%$ in view of the environmental and economic aspects. 3) It is necessary to change the existing system into the District Unit oriented planning & design method in order to apply the environmental design elements in smooth manner.

Environmental matters have more influence on business performances. Consequently, as a way to cope with environmental matters, much more interests in environment-friendly management have increased recently. First-rated hotels and food-service restaurants have been concentrating on gaining ISO 14001 EMS(Environment Management System), which is regarded as objective and international, to solve and prevent environmental matters. However, there are some internal and external problems emerged in the food-service industry and first-rated hotels. Therfore, covering the examples of ESH(Environment Safety Health) management which was developed by H group and based on ISO 14001 EMS, this study aims to observe merits of ISO 14001 EMS as a model that can develop an environment management system, and to consider an improvement plan for better understanding of licensed cooks in restaurants.

The purpose of this study is to establish the management plannings for the conservation and environmentally friendly use of Korean coastal wetlands. The function, economic value, and the necessity for the conservation of coastal wetlands are described. The current management status, Korean Governmental policies for the use of coastal wetlands, and their problems are surveyed and analysed. The management plannings for the environmentally friendly use of Korean coastal wetlands is suggested as follows: (1) The coastal wetlands need to be divided into 3 different regions based on PSR(Pressure, State, Response) of OECD. (2) Each region should be managed by appropriate management plans which are suggested in Chapter IV of this paper. Finally, in order to realize these management plannings the change of Governmental system and laws are suggested as follows: (1) The change of relevant laws is required. Additionally, each region should managed by proper governmental agencies. (2) The EIA(Environmental Impact Assessment) system should be improved. (3) The participation of regional people should be guaranteed in the decision making processes of the business and other important planning regarding coastal wetlands. (4) The system which primed the ecological value of coastal wetlands should be established.

The water-gas shift reaction for the compact reformer was carried out at a gas hourly space velocity of 72,152 h^-1 over the Cu-Nb-CeO₂ catalysts prepared by co-precipitation method. In order to investigate the effect of Nb₂O₅ promotion over a Cu-CeO₂ catalyst, the Nb₂O₅ loading amount was systematically changed from 0 to 5 wt.%. Among the prepared catalysts, the Cu-Nb-CeO₂ (1%) catalyst showed the highest catalytic activity (CO conversion=61% at 400℃) as well as 100% CO₂ selectivity. The high activity and stability of Cu-Nb-CeO₂ (1%) catalyst are correlated to high Brunauer-Emmett-Teller surface area, small metallic Cu crystallite size, and enhanced redox property.
