Global warming caused by excessive greenhouse gas emission is causing climate change all over the world. In Korea, greenhouse gas emission from residential buildings accounts for about 10% of gross domestic emission. Also, the number of deteriorated multi-family housing complexes is increasing. Therefore, the goal of this research is to establish the bases to manage energy consumption continuously and methodically during MR&R period of multi-family housings. The research process and methodologies are as follows. First, research team collected the data on project characteristics and energy consumption of multi-family housing complexes in Seoul. Second, an ontology-based breakdown structure was established with some primary characteristics affecting the energy consumption, which were selected by statistical analysis. Finally, a predictive model of energy consumption was developed based on the ontology-based breakdown structure, with application of CBR, ANN, MRA and GA. In this research, PASW (Predictive Analytics SoftWare) Statistics 18, Microsoft EXCEL, Protege 4.1 were utilized for data analysis and prediction. In future research, the model will be more continuous and methodical by developing the web-base system. And it has facility manager of government or local government, or multi-family housing complex make a decision with definite references regarding moderate energy consumption.

In this study, an analysis was performed on the performance of the solar water heating system with geo-thermal heat pump for a detached house. This system has a flat plate solar collector ($8\;m^2$) and a 3 RT heat pump. The heat pump acts as an auxiliary heater of the solar water heating system. These systems were installed at four individual houses with the same area of $100\;m^2$. The monitoring results for one year are as follows. (1) The average daily operating time of the solar system appeared to be 313 minutes in spring (intermediate season), and 135 minutes and 76 minutes in winter and summer respectively. The reason for the short operating time in summer is the high storage temperature due to low water heating load. The high storage temperature is caused by a decrease in collecting efficiency as well as by overheating. (2) The geothermal heat pump as an auxiliary heater mainly operates on days of poor insolation during the winter season. (3) Despite controlling for total house area, hot water consumption varies greatly according to the number of people in the family, hot water usage habits, etc. (4) The yearly solar fraction was 69.8 to 91.5 percent, which exceeds the maximum value of 80% as recommended by ASHRAE. So the solar collector area of $8\;m^2$ appeared to be somewhat greater for the house with an area of $100\;m^2$. (5) The observed annual efficiency of solar systems was relatively low at 13.5 to 23.6%, which was analyzed to be due to the decrease in thermal efficiency and the overheating caused by a high solar fraction.

This paper is aimed at exploring a multi-racial, multi-ethnic, and multi-cultural trianglulation of Black, White, and Korean American race relations connected to a large-scale disturbance in the 1992 Los Angeles riots. The second generation Korean American Steph Cha's Your House Will Pay (2019) focuses on a social portrait of the racially marginalized beings as Korean immigrant merchants and African American native consumers. This family saga explores issues resulting from racial hierarchy, racialized stereotypes, and historical marginalization in the internalized sociometry of race and class inequality. This work grapples with issues involved in a sociocultural web of racial triangulation under the white dominant structure, and ensuing intergroup conflicts of social minorities in the economic geography of urban space. It opens up civil discussions for transracial, transethnic, and transcultural interactions and coexistence. It ultimately leads to extending young people's minds for a deep understanding of the socioecomonic landscape of racial matrix, and enhancing the cultural literacy for a better awareness of social empathy and the communal respect of life.

A Gamsil is an ritual instrument which enshrine the ancestral tablets of four lines from late great-great-grandfather and grandmother to late father and mother. This has their soul. Juja's "Garye" informs its structure pattern. It is placed in Sadang and takes the form of a perfectly square box. It partitions four rooms and enshrine an ancestral tablet room by room. They get the ancestral tablets line up from west to east. And they also enshrine the ancestral tablets without his descendant together in Gamsil. A Gamsil is a space to enshrine the ancestral tablets and to place an order within a family. A social status and A family economic power become a standard in making and managing Sadang. Kingdom in Joseon period limited the ancestral tablets considering of his degree of official rank which descendant enshrined. A official servant can be stable economically in getting a stipend and build sadang in the house. While household a little in economic enshrine the ancestral tablets at a Gamsil placed at the a space of private home. His personal circumstances make size and pattern, place change in relation to Gamsil. A Gamsil looks like house in structure and pattern. It has the immortality of the soul. And it changed from a table size to a ancestral tablet size. This Gamsil is comfortable to move and is made considering of the width and height of household. The transition of Gamsil means institutions is in close to a family economic power in social change. Kingdom in Joseon early period makes a policy of a Gamyo's build and an ancestral enshrine in basement of Juja's "Garye". The transition of Gamsil gave a common people limitted socially and institutionally the service of late four lines. Most of people enshrine the ancestral tablets of their four lines in approaching of in the late of Joseon Dinasty. They compromise on their reality and cause. The transition of Gamsil implied many different things in social ; the authenticity search and a dignity expression of his family, the foundation for the diffusion of an ancestral service, a space sharing with ancestor and descendent, the increment of a family economic power etc.

The purpose of this study was to investigate the possibility of applying the planning characteristics of Neowa houses to contemporary residential structures. Contrary to the popular assumption that traditional Korean houses have decentralized plans, local building traditions observed in Neowa houses show that the diversity among hanoks allows the incorporation of traditional spatial organization into the contemporary residences. By analyzing the spatial organization of Neowa houses, three advantageous planning characteristics were found. First, the presence of indoor wooden floors (maru or daechung) as well as outdoor wooden floors in Neowa houses is practical for Korea's weather marked by humid summers and icy winters. Secondly, the internal orientation of space in Neowa houses is more appropriate in the contemporary context of a highly urbanized society emphasizing family privacy. Thirdly, the flexibility and interchangeability of interior elements can be applied to improve efficiency. By applying the aforementioned characteristics, this study suggests ways to adopt traditional features to improve contemporary residences.

The purpose of this study was to compare time use pattern of Korean working couples with those of Japanese counterparts. The data for240 Korean couples living in Seoul and 162 Japanese couples living in Tokyo were collected using structured questionnaire and time diary. The time use patterns of couples were analyzed according to employed status of wives. The results were as follows. The similar time use patterns were found between couples of two country. However the amount of time allocated for daily activities was found to be somewhat different. The amount of time spent by husbands on paid and house work was found to be different according to their wives employment status. The orean husbands of full-time employed wives and the Japanese husbands of part time employed wives spent the longest time on paid work. The Japanese husbands of full-time employed wives spent much more time on housework than those of Korean counterparts did. The social-cultural time of Korean couples was enerally longer than that of Japanese couples. The Korean couples spent more time on watching TV whereas the Japanese couples used more time doing family activities hobbies and moving for social-cultural activities.

The purpose of this study was to investigate the relationship between householder's education level and the education expenditure for children. The Family Income and Expenditure Survey data of the 2005 National Statistical Survey were used to examine the hypothesis. For data analysis, ANOVA and regression method were applied. The results are as follows: House-holds in Seoul spent 533,000 won for child education per month on the average, and 64% of the expenditure was for private education. Households whose householder's education level was high spent more expenditures on public and private education for children than the households whose householder's education level was low. When the household income level was controlled, householder's education level affected only private education expenditure.

Seoul citizens are currently suffering from high housing price. Home prices have risen more rapidly than salaries so owning a housing unit (apartment, condominium, or single-family home) in Seoul is becoming more difficult than ever. Therefore, this research examines the behavior of average Seoul citizen in owning housing unit in Seoul, Korea, particularly in terms of the length of time required to afford a house unit. This research estimates that it will take about 18.75 years in maximum after getting a job (12.75 years after purchasing the housing unit) to own housing unit in Seoul that is currently valued at $300,000 where the growth rate of income is 2.97% and consumption price increases at a rate of 2.95% per annum. Finally in this research, the optimal growth rate of housing price is estimated ranged from 3.5 to 4.0% minimizing the loan payoff period.
