Currently energy use planning council system is mandatory especially for the urban development project planned on a specified scale or more. The goal of existing demand prediction was to calculate the maximum load by multiplying energy load per unit area by building size. The result of this method may be exaggerated and has a limit in the information of period load. The paper suggests a new forecasting process based on standard unit household in order to upgrade the limit in demand prediction method of multi-family housing complex. The new process was verified by comparing actual using amount of multi-family housing complex to forecasting value of energy use plan.

The study aims to explore the problems of analysis unit when examining management performance and efficiency using DEA (Data Envelopment Analysis). Generally the DEA results depend on input, output, and analysis units. We used data from Park (2012) which analyze paddy farmers in Jeonnam province. Results show that data from farm household unit was well fitted to examine management efficiency, not data from per area unit. This study will be helpful for researchers and practitioners to understand proper analysis unit when using the DEA for enhancing farm competitiveness.

This study was carried out in order to examine the health status of arthritis patients living in K city of southern part of Korea. The data were collected with AIMS2 instrument from 56 subjects who were asked to complete the questionnaire by the trained surveyor. The AIMS2 has been approved useful instrument for assessing the outcome of various treatments and programs in rheumatic diseases. The component variables of the AIMS2 are Mobility, Walking and Bending, Hand and finger function, Arm function, Self-care tasks, Household tasks, Social activity, Support from family and friends, Arthritis pain, Work, Mood, Level of tension, The total number of items of AIMS 2 are 78. The results are as follows: The average age of the subjects was 58 years old and no gender difference. The mean scores of the 12 sub-concepts of AIMS2 are 15.0 of mobility, 12.16 of walking and of bending, 9.32 of hand and finger function, 9.03 of arm function, 13.53 of self-care tasks, 10.19 of household tasks, 15.09 of social activity, 19.58 support from family and friends, 13.82 of arthritis pain, work, 14.85 of level of tension, 15.12 of mood. The Cronbach Cronbach $\alpha$. is 0.72-91 for RA patients and 0.74-96 for OA patients. This results showed that the health status of Arthritis patients at home in K-city was almost not so serious, but the level of tension and mood were quite higher than the average score.

Korea ranks high among the OECD member countries with a high out-of-pocket share. In 2006, the government implemented in full scale the policy of extending the health insurance benefit coverage. Included in the policy are lowering the out-of-pocket share of patients of serious case and expanding the medical bill ceiling system to mention just a few. This study proposes to confirm effectiveness of the benefit extension policy by identifying changes in 'out-of-pocket expenditure as a share of the ability to pay' and 'incidence rate of catastrophic health care expenditure' of each individual household as manifested before and after the benefit extension policy was implemented. The 1st and 3rd year data from the Korea Welfare Panel Study (KoWePS), conducted by the Korea Institute for Health and Social Affairs (KIHASA), were used for the analysis, where low-income households and ordinary households are sampled separately. While the absolute amount of 'out-of-pocket expenditure' occurred to the average household increased for the period 2005-2007, the 'out-of-pocket expenditure as a share of the ability to pay' decreased. At the same time, the share decreased in the case of low-income households and households with patients of chronic or serious case as contrasted with ordinary households. 'Incidence rates of catastrophic health care expenditure' of ordinary households for 2007 stood at 14.6%, 5.9% and 2.8% at the threshold of 10%, 20% and 30%, respectively. The rates decreased overall between 2005 and 2007, while those of low-income households with patients of serious case statistically significantly increased. An analysis of this study indicates that it is related with the medical bill ceiling system regardless of incomes introduced in 2007.

In this study the phenomenon of commodity substitution of housework is approach in the contexts of economic system, patriachal family system and housework-related human resources. the objectives of this study are as follows: (1) To measure the level of commodity substitution of housework in large cities. (2)To investigate the factors influencing commodity substitution of housework. The samples were composed of 982 housewives dwelling in 6 large cities including Seoul. The statistics used for data analysis were frequency distribution, percetile. multiple regression analysis. The major findings are the following; (1) When the housework was divided into two subdomains , in the domain of food the purchase level was for below average while in the domain of clothes, the level was quite higher than average. This result hows that commodity substitution has become more common in the domain of clothes by mass production of clothes on a commercial scale. (2) the level of commodity substitution of housework was influenced by the family attribute variables such as housewife's age, family income. housewife's education, family types, housewife's brought-up regions, presence of sewing machine, employment status of housewife, by one patriarchal norm variable such as home-orientedness, and by tow human resource variables such as importance of housework and household tasks performance competnecy. Among variables house wife's age was the most influential one and such variables as family income, housewife's education, household task performance competency, importance of housework, and home-orientedness were also important. Considering that the influence of home-orientedness demonstrates the importance of patriarchy and that importance of housework and that performance competency also are determined by the patriarchal variables such as sex-role attitude and home-orientedness, we can conclude that Hartmann's theoretical approach with which the changes of housework were explained in the two contexts of economic system and family system is applied to the changes of housework in Korea.
