  • In order to develop an accurate analytical model for domestic electricity demand forecasting, we propose a prediction method of the electric power demand pattern by combining SMO classification techniques and a dimension reduction conceptualized subspace clustering techniques suitable for high-dimensional data cluster analysis. In terms of electricity demand pattern prediction, hourly electricity load patterns and the demographic and geographic characteristics can be analyzed by integrating the wireless load monitoring data as well as sub-regional unit of census information. There are composed of a total of 18 characteristics clusters in the prediction result for the sub-regional demand pattern by using census information and power load of Seoul metropolitan area. The power demand pattern prediction accuracy was approximately 85%.

  • This paper presents the result of pattern classification of load demand for distribution transformer in domestic. The field data of load demand is measured using the load acquisition device and the measurement data is used for the database system for load management of distribution transformed. For the pattern classification, the load data and the customer information data are also used. The K-MEAN method is used for the pattern classification algorithm. The result of pattern classification is used for the 2-step format of load demand curve.

  • This paper presents a forecasting method for domestic demand of electric home appliances. Because of lack of data, some popular methods such as time series analysis may not be appropriate to forecast such a demand domestically. We suggest a systematic and practical method by considering structural parameters and variables which determine the actual demand. We use this model to forecast the demand of color TV. Since the parameters in our model may be variant according to the change of economic environment, our model leads the user to develop a dynamic model to be used in the well-known System Dynamics Approach.

  • In case of the service of the existing PC package game, the production cost and distribution cost is high, the illegal copies by Internet is widespread. To prevent, game production companies and distributors provide a GOD(Games On Demand) service that players download the game content by internet to play games. But, there is little research on current status of GOD service in the country. Therefore, in this paper, we define GOD service, analyse the structure of GOD service, describe domestic current status and research on the problem and solutions of GOD service. This paper gives useful information to companies providing GOD.

  • The electric demands increase, financial need for new power plant constructions and environmental problem have led to search for more efficient energy production and load management. To minimize the construction of power plants and reduce total power consumption include installation of demand controller to industrial applications. Accordingly to maximize the load control by the diffusion of demand controller, govermental economic supports as well as the analysis of energy saving effects. This paper presents the cost-effectiveness analysis for DSM program evaluation and case study to analyze demand controller DSM program.

  • This study analyzes the impact of Import beer demand on Anti-Japanese sentiment. Recently anti-Japanese sentiment heightened by the media was found to be drastically reducing the consumption of Japanese beer in the domestic imported beer market. Thus, the study used the import demand function of imported beer to analyze the impact of the 'Priming Effect' on the consumption of imported beer by anti-national sentiment, indicating a significant drop in Japanese beer consumption in other countries. Therefore, this study used the imported beer import demand function by country to analyze the impact of the priming effect on imported beer consumption according to anti-national sentiment. As a result, in the case of imported beer consumption in other countries, it was estimated that indirect consumption substitution occurred considerably.

  • The future demand of the satellite broadcasting service is analyzed through the competitive diffusion model. Diffusion rates of the satellite broadcasting service in the case that the decreasing effect due to the cable TV service is considered are smaller than those in the independent case. Diffusion rates of the satellite broadcasting service are shown to become different according to environmental conditions.

  • This Study analysed subjective perceptions of culinary arts major students who participated in overseas employment program for providing vital information for future program development. The study adopted Q methodology as an analogizing tool and found four distinctive types. The first type is Link to Domestic Employment Type(Type 1, N=6), the second type is Finding New Enterprise needed Type(Type 2, N=8), the third one is Major Customized Language Education Demand Type(Type 3, N=3), and the last one is Major Divided Education Demand Type(Type 4, N=2). The results indicated that importance of establishing a bridge between overseas employment and domestic employment with providing specific information of domestic job recruiting process. It is also emphasized that informing extra available job placements for the students is vital. Lastly when the sub program were formed, it is necessary to divide students based on not only overseas employment destination but also their major.

  • Korea has recently experienced a large change in civil architecture and urban environment. However most of civil architectures and urbanization have been accomplished without considering economic efficiency and impact. This study focuses primarily on an analysis on the relationship between architecture and economic efficiency through the foreign and domestic case studies. Secondly, it is going to elucidate the economic properties on Korean architecture recently established. With perspectives of the analysis, we need to consider the following factors in the production of architecture; labor intensive industry, seasonal industry, strong and domestic demand.
