Purpose: The objective of this study is to divide personal traits of the elderly living in a rural area into extraversion, agreeableness, openness, conscientiousness, neuroticism, and loneliness and to identify the relationship between personal traits and receptivitiy to sharing living space in communal shared housing. Method: Subjects of this study are the elderly of ages greater than 55 living in Yeongwol-gun, Gangwon-do. Depending on how often elderly welfare facility was used, places where the elderly gathered were divided into a senior citizen center, senior welfare center, and other places where they often gathered. The researchers visited each of the places directly and conducted a survey with face-to-face interviews. Result: The collected data consisting of 124 respondents were analyzed through SPSS statistical program. It showed that 5 personal traits, except for agreeableness, had statistically significant difference. Extrovert and low lonely elderly people had high receptivity. The relationship between personal traits and acceptable shared space revealed differently depending on the function of space. Especially, shared resting space was related to low emotion-oriented trait, such as neuroticism and loneliness, while shared hobby and sanitary space were related to strong management-oriented trait of conscientiousness. These findings demonstrate the importance of understanding personal traits in predicting receptivitiy to sharing living space. Also, it is necessary to compare the degree of receptivity to sharing living space based on personal traits and to plan shared space in several levels, such as full sharing, partial sharing, and individual use, to develop and supply communal shared housing successfully.

Purpose: Since the 19th century many concrete models and theories for the ideal city had been proposed and in some way had affected on the ideal urban plans in the 20th century. Modern cities in the 20th century faced a total chaos, due to the world war and new social paradigm came from the development of technology. These social context leads us to be interested in ideal city. And two planned cities; Chandigarh, India and Brasilia, Brasil, are meaningful as the result of the modern ideal city in the early 20th century even though they completed just in part. Method: This study is focused on the characteristics of the modern ideal city in the early 20th century based on comparison with two realized cities. There are similarities and differences in their background, concept, and the characteristics of form and space. Result: First, both cities are required to make monumental and symbolic images by political issues. For this, Le Corbusier proposed the grid system for a metaphorical city and L. Costa defined the urban form with abstract axis for a mythological city. Second, the administrative districts in both cities are planned as symbolic places by formative buildings and their hierarchical arrangement. For neighbourhood unit 'Sector' in Chandigarh and 'Superquadras' in Brasilia are used for the neighbourhood unit respectively. Third, the car-oriented road system and urban environment by population overcrowding in tow cities are criticized in common. Consequently, as we can see, the modern ideal city in the early 20th century succeeds in making symbolic urban image, but exposes the limitation of sustainability.

Purpose: This preliminary study investigated a potential of the water wall systems that provide heat storage and natural lighting control simultaneously. Method: In order for transparency of the water wall to be controlled, the study first proposed two measures: to adjust transparency of the water wall; to control transparency of water wall surface. The performance of two measures then was verified and compared by experiments. In addition, a trade-off between heat collect and heat storage resulting from using additive for adjusting transparency was investigated. Result: The experiment showed that the two measures are similar in performance. The investigation of trade-off relation showed the additive should have the same heat storage as the water to prevent decrease in thermal performance of the water wall. As an economical measure to control transparency of the water wall, this study suggested a measure of secondary heat transfer systems using shading device that first absorbs solar radiation and then transfers heat to the water wall. The experiment show that performance of the proposed measure is similar to controlling transparency of water wall surface. In conclusion, it is expected that the performance of the water wall can be economically maximized by using the proposed mean in terms of heating, cooling and lighting energy saving.

Purpose : The energy saving in a residential building (apartment) sector is known as one of the effective solution of energy reduction. In South Korea, the government has recently reinforced regulations associated with the energy performance of buildings. However, there is a lack of research on the methods for the energy performance diagnosis that is used to analyze the wall thermal performance of the existing apartments. Because a reliable diagnosis is necessary to save the building energy, this study analyzed wall thermal performance of an existing apartment in Seoul. Method : This paper applied two methods for analysis of the thermal insulation performance; HFM(Heat Flow Meter) method and ASTR(Air-Surface Temperature Ratio) method. The HFM method is suggested by ISO9869-1 code to measure the thermal performance. The ASTR method is proposed by this study for the simplified In-situ measurement and it uses three temperature data (interior wall surface, interior and exterior air) and the overall heat transfer coefficient. This study conducted the experiment of an existing apartment in Seoul using these methods and analyzed the results. Furthermore, the energy simulation tool of the building was used to suggest retrofit of the building based on the results of measurements. Result : The error rate of HFM method and ASTR method was analyzed in about 17 to 20%. As the results of comparison between the initial design values of the wall and the measured values, the 26% degradation of insulation thermal performance was measured. Lastly, the energy simulation tool of the building shows 10.8% energy savings in accordance with the construction of suggested retrofit.

Purpose: Frequently, the apartment management offices have difficulties in effective repair works due to their insufficient technological capability to operate long-term repair program. There also have been many cases of failure in executing urgent repairs mainly because the repair allowance has not accumulated enough for the repair works on time. This study aimed to determine core items in apartment maintenance in order to reduce the confusion and unnecessary efforts for the management office by suggesting simple list of repair items. Method: Core items are defined using several indicators. The degrees of necessity for repair work(NRW) are calculated combining the impacts to living, safety, and aesthetics. Then the degrees of burden of repair cost(BRC) are estimated by analyzing actual long-term repair program of three apartment complexes. Lastly the degrees of accumulation demand for repair allowance(AD) are calculated with NRW and BRC. Result: The core items and essential items are suggested for three apartment types as case studies based on the indicators of NRW, BRC, and AD. Then, the required accumulated allowance per $m^2$ was calculated to effectively implement repair works.
