In korea, the power consumption is increasing every year because of economic growth, requiring of convenience and delightfulness condition. As increasing power consumption, Private Use is steadily increasing and the rate of electrical accident is increasing. Therefore we research the electrical safety culture of our people by the survey of electrical safety. The subject to investigation is possessor, occupier of Private Use and electrical safety manager. This paper will be used to base data for the protection of electrical accident and facility accident at Private Use

In the past, pumping-storage generator pumped the water from the lower part storage to the upper part storage during the base load periods. And, it generated during the peak load or when other generator was outage. However, pumping-storage generator will operate different ways in the competitive power markets. It will pump during lower price periods and generate at higher price periods. This paper presents economic analysis of pumping-storage generator using price (or SMP) duration curve.

Organic fanning in the UK has been greatly grown for the last decade. Two policies for supporting organic farming introduced in 1994 and 1999 played a crucial role in expanding organic farming area and increase in the number of farmers taken up organic fanning methods. Comparing the two policies, this paper identifies that the significant increase in financial aid to organic fanning in 1999 not only was a key factor to succeed in the scheme but also provided environmental base for further development of rural areas. However, such a national aid scheme should be improved in order to reflect regional specific characteristics in terms of environmental protection and local social and economic development. the experience of the UK suggests that the role of organic fanning in rural economics should be defined before enhancing financial support to farmers.

The main objective of this study was to develop a basic information base on Chinese consumers related to clothing purchases. Previous studies on Chinese consumers were extensively reviewed and in-depth interviews were conducted with 12 middle-level managers at Korean apparel companies which market their merchandises in China. Combined results from the reviews on previous studies and interviews indicated that traditional values, communism and industrialization are the major forces which shape contemporary Chinese consumers. Industrialization, in particular, accompanied by influx of western culture and economic development, has resulted in wide-spread phenomenon of conspicuous consumption. Thus, brand and brand images appeared to be the most important considerations for purchasing imported apparels. In addition, diversity of Chinese consumers and geographical differences were emphasized, which indicated need for market segmentation. Other characteristics including body measurements also provided implications for fashion marketing in China.

This study was conducted by the tests of materials engineering and soil mechanics to see the strength characteristics of the ‘Cement-Mixed Soil'. To sum up my experiments, I would like to present the results which are the theoretical base and fundamental data to establish the standard design including the design of mixing proportions of the soil as a construction material. In conclusion, in this study the optimum cement mixing ratio is $9\%$ and in this ratio the optimum moisture content of compaction work is $19.3\%$ from the analysis of the strength characteristics, as well as in consideration of the economic profits and nature familiar facts.

This study aims at examining each firm's decision-makings of complex product and system (hereafter CoPS) innovation strategy, so that it tries to reveal the nature and role of CoPS innovations strategy. And it designed a comparative case study along with qualitative methods, by having two mobile operators' digital rights management (hereafter DRM) innovation in South Korea's digital music service industry. Through literature review, this study formulated three research propositions: (i) Each firm's decision-makings of CoPS innovations strategy are analytical negotiation process among economic actors in an industry; (ii) Each firm's market power originated from its market share from the installed base through network effect and switching cost influence decision-makings of CoPS innovation strategies; (iii) Each firm's decision-makings of different CoPS innovation strategies are related to their intension of achieving better market power, consequently dominant design. Through empirical examination of two mobile operators' decision-makings of DRM innovation strategy, this study empirically verified three research propositions.

For the electric power system operation, the information to monitor the operation status of power plants and transmission lines is very important factor in the view point of system security and economic operation. This paper presents the logical and physical structures of database used by KEPCO's EMS. The adopted DataBase Management System (DBMS) of a relational model type offers many advantages such as easy maintenance of database. In addition, this paper briefly introduces the data exchange system between application programs and database.

The rare metals, used for semiconductors, PDP-LCS and other specialized metal areas necessarily, has been playing a key role for the Korean economic development. Rare metals are influenced by exogenous variables, such as production quantity, price and supplied areas. Nowadays the supply base of rare metals is threatened by the sudden increase in price. For the stable supply of rare metals, a rational demand outlook is needed. In this study, focusing on the domestic demand for chromium, the uncertainty and probability materializing from demand and price is analyzed, further, a demand forecast model, which takes into account various exogenous variables, is suggested, differing from the previously static model. Also, through the OOS(out-of-sampling) method, comparing to the preexistence ARIMA model, ARMAX model, multiple regression analysis model and ECM(Error Correction Mode) model, we will verify the superiority of suggested model in this study.

Multi-use housing and commercial buildings have been emerged according to social and economic changes of CBD in Seoul Metropolitan Areas. The purpose of this study is to clarify the characteristics of the multi-use building, to analyze the problems on the base of survey and to suggest the solutions for architectural planning, focusing on eco-friendly dwelling environment. A field survey with 46 subjects has been carried out with structured questionnaire. Some problems in planning of the complex building have been discussed in terms of environmental issues and design criteria. In conclusion, basic planning directions for improving the building environmental quality have been suggested.

The purpose of this study is basic research for demand forecasting of residence which will form in the new industrial complex. Our industrial complexes are important base of National economic development until 90's. But The industry complexes which confront facility which is old, Maintenance negligence and change of industrial system must change new shape from existing function of industrial complexes. The results of this study are that the present housing using condition are different at ages and Using intentions of staff facility are negative generally. These means that When starting the structure hightening, the utility system provision and public information of residence facilities in industral complex are necessary for workers. So, The key points of industry complex structure hightening are that the accurate recognition about demand and the development of financial support policy for young Income low-end workers do to make advance efficiently.
