For the optimal design of the induction heating cooker, precise and accurate analysis of the magnetic field inside the jar must be achieved first. Until now, design methods based on experience has been used in industry field. But this takes a lot of trial and error, high cost and also long development time. So the analysis of the magnetic field distribution is very important. In this paper the magnetic field inside the induction heating cooker is analyzed by using axisymmetrical FEM(finite element method). And the method of the coil location design for the optimal heat source distribution using sensitivity analysis is developed. In addition, the shielding effect of the non-axisymmetrical 3-D ferrite structure used in induction heating cooker is also analyzed by the integral method.

The Publicly Purchased Property (PPP) Program since 2004 has allowed low-income households to reside in decent housing at a reasonable expense and to live in a community they choose. With an increasing number of the housing stock, management of the properties becomes a growing concern. The purpose of this research is to find out the satisfaction of the tenants with residential environment and housing management. To collect data, a face-to-face interview survey was conducted for 310 households living in the designated properties of 8 cities in and outside the Seoul Metropolitan Area (SMA). Most of the households were a family of three headed by late middle-aged man and lived in physically sound, small-sized units at an affordable cost. Overall satisfaction with living environment was higher in non-SMA than in SMA, and influenced by building deterioration and unit size. Further, most of the respondents were in favor of housing management services provided by a nearby public housing estate. Building deterioration and regular onsite visits of management staff were determinants in the satisfaction with housing management. The results indicate that proper housing management delays building deterioration and assures decent living for low-income people, leading to high levels of residential satisfaction.

Purpose: Most if buildings need various repair works for preventing or delaying the deterioration which gives rise to affect the living condition or function after constructed. Therefore, a long-term repair schedule should be planned and a repair cost is required. In this paper, it aimed at providing the statistical forecast model for a repair cost in roof water-proofing work and elevator work using statistical approach with three variables such as number of household, management area and a elapsed year. Data are collected in apartment housings which are located in Seoul area and conducted with interview and questionnaire sheet. Each analyzed work is divided into a partly work and fully work. Results of this study are shown that, first, the regression model takes a multiplying type like a Cobb-Douglas function and is changed into the log-linear type to include the three variable simultaneously. Second, the goodness-of-fit of the repair cost forecasting model has a good statistics in determinant's coefficient and Dubin-Watson value. Third, the management area is stronger factor than other the number of household and an elapsed year in roof water-proofing work and elevator work.

This paper first makes a survey of fishing household economy which possess fishing boats under 10 gross Tons by a questionnaire, and makes a comparative study of major indicators of fishing household economy between Korea and Japan, and finally suggests some policies for the fisheries management. Major indicators are the status of fishery household members, number of fishing boats which possess, fisheries incomes, fishing household incomes, side business incomes of fishing household, disposal incomes, living expenses, sufficient degree of living cost, average propensity to consumption and so on. Some policies for improvement in fishing household incomes are suggested in the paper as follows: ⑴ Form a policy similar to a project aiming for increasing the income of fishermen so that the side business income will also increase. ⑵ The point of view in tracing origin of low productivity. ⑶ It has drawn up a plan to encourage saving after analyzing the cause of high propensity to consumption. ⑷ The paper is aimed to collect basic statistical materials for fisheries administration.

Due to the big fire in Uijeongbu, the status of construction, fireproof materials and structural method were examined to prevent fire propagation through outside insulation parts of urban living homes. Through research and experiments, the following results were obtained. It was confirmed that outside heat-insulation wall method was used in a large number of urban living homes which were made of materials and structures spreading fire easily.Through experiments, it was revealed that lightweight plate material, as a fireproof material, can save the cost as well as the period of construction and obtain more than 30 minutes of evacuation time which is twice the maximum evacuation time.

The sofa industry, which is now one of the major furniture industries in Korea, has developed since 1970s as the apartment building boom and the rise of living standards triggered its demand. Among others, durable and high-quality leather sofa had been most favored and excelled other sofas since mid-1980s along with the growth of national economy before IMF control tightened money market in late 1990s. Leather sofa is still favored and its industry has great possibilities to increase as people tend to seek higher and more personalized living conditions with the stabilization of economy. However, there are several problems in the sofa industry due to the current economic difficult conditions, i.e.; 1. It is hard to cut down the cost of raw material as the supply mostly depend on import. 2. It is hard to keep product quality due to technical difficulties. 3. There are still illegal duplicates of foreign or domestic competitors'design. The aim of this study is to examine the reality of the leather sofa industry in Korea and to suggest new vision for its progress.
