In this study, remodeling projects are perceived as a sustainable urban management policy to boost the value of old apartments and stimulate urban regeneration and development. To evaluate the physical environmental performance of external spaces of remodeled apartments, an evaluation model was developed. After applying it to the target places, the following results were obtained. First, analysis of the external space change index of the target apartments revealed that institutional standards are necessary in line with the building arrangement type, parking lot expansion method, and changes in the building-to-land ratio. Second, the score ratio as to the external space change index performance is as follows: safety (48.30); pleasantness (25.90); convenience (18.90); eco-friendliness (14.90). In other words, "safety" had the biggest score ratio. Third, to boost the external space performance of remodeled apartments, the needs of residents and neighboring environmental plans should be considered from a communality standpoint.

This study was conducted to analyze the reasons for aging in place through an in-depth interview, which is a qualitative research method. The subjects of the study were 17 adults over the age of 60 years who preferred aging in place. Interviewees were asked questions about their experiences of past living, present living, and the future place where they want to live in and the reasons for their choice. In the in-depth interviews conducted from September 2012 to May 2013 for data collection the research participants were asked open-ended questions about their past living experiences and future living plan and were given the freedom to answer the questions in their own words. The results of the in-depth interviews revealed the following reasons for aging in place: 1) familiarity due to long-term residence, 2) strong attachment to the place and the neighbors, 3) satisfaction of present house, 4) personal stories associated with present house, 5) feeling of living in their own home, 6) convenience of the neighborhood for living, 7) caring relationship with the neighbors, 8) fear of a change of environment, and 9) resignation to the rest of their life. The findings indicated that residential types in old age need to be taken into account for both aging in place which referring to choosing to live where one has lived for years and referring to involuntarily staying where one has lived for years.

The change of idea about overall politics, society, technology, and culture in 20th century led to the change of kitchen which is the central space of household affairs as well. Frankfurt kitchen of Margarete Schuette Lihotzky which was introduced for the first time at Germany International Trade Exhibition in 1927 functionally designed small space of $6.5m^2$ with considering move-line and convenience. This is the beginning of kitchen type which has built-in sink and cupboard that is regarded as an universal option these days, and this has extensively been applied to kitchen system throughout the world after the repetitive development in America, Sweden and Switzerland. And improved kitchen of Park Gil-Yong which was influenced by rationalism introduced from the house improvement campaign and the opening of a port which were progressed in Korea in $1919{\sim}1930$ is the first stand-up kitchen which improved the inefficiency of Korean conventional kitchen. The purpose of this study is to understand the change aspect of kitchen through the rationalization in each country by comparing the introduction background of the times, change of space for residence and kitchen, and the characteristics of kitchen plan which had influence at the turning point on the kitchen in Korea, Europe on the side of efficiency at the same period, take into consideration of our residing-culture which has rapidly been changed between tradition and modernity, and to see the direction of kitchen design which copes with the unique residential environment.

Purpose: Apartment is a typical residential type in Korea. In the past, apartment types were very monotonous. But today, the types of complex are changed because personal needs have been diversified and personalized. In order to meet those needs, construction companies are constructing various types of apartments. The more apartment types are diverse, the more the energy problems are taken place. So, the purpose of this study is to solve the problem of energy gap in the same complex through improving the thermal transmittance of wall. Method: Heating energy consumption of Building Energy Efficiency Rating System and heating energy usage of apartment show a similar trend on the graph. In order to identify the best position of heating energy consumption difference reduction, we change the building's U-value of front, back, side walls. Result: In the A complex, maximum and minimum heating energy consumption building's shapes are flat. the best efficiency is side U-value change and the worst is front change. In the E complex, maximum heating energy consumption building's shape is tower and minimum building shape is flat. Consequently, the front and back wall performance change was little effect to reduce energy gap, while the change of side wall's U-value show the great reduction between building's energy consumptions.

Urban expansion, particularly converting sub-urban areas to residential and commercial land use in metropolitan areas, has been considered as a significant signal of regional economic development. However, this results in urban climate change. One of the key impacts of rapid urbanization on the environment is the effect of UHI (Urban Heat Island). Understanding the effects of urban land cover change on UHI is crucial for improving the ecology and sustainability of cities. This research reports an application of remote sensing data, GIS (Geographic Information Systems) for assessing effects of urban land cover change on the LST (Land Surface Temperature) and heat budget components in Ho Chi Minh City, where is one of the fastest urbanizing region of Vietnam. The change of urban land cover component and LST in the city was derived by using multi-temporal Landsat data for the period of 1998 - 2020. The analysis showed that, from 1998 to 2020 the city had been drastically urbanized into multiple directions, with the urban areas increasing from approximately 125.281 km² in 1998 to 162.6 km² in 2007, and 267.2 km² in 2020, respectively. The results of retrieved LST revealed the radiant temperature for 1998 ranging from 20.2℃ to 31.2℃, while that for 2020 remarkably higher ranging from 22.1℃ to 42.3℃. The results also revealed that given the same percentage of urban land cover components, vegetation area is more effective to reduce the value of LST, meanwhile the impervious surface is the most effective factor to increase the value of the LST.

Purpose: Under the purpose of presenting the adequate remodeling period for the improvement of thermal insulation performance of external walls in deteriorated buildings, the change in external wall and residential environment problem(dew condensation) due to aged deterioration after the apartments were constructed in Korea were analyzed. Method: Temperature Difference Ratio Outside(TDRo) and Heat Flow Meter(HFM) were used as measurement methods to evaluate the thermal insulation performance of deteriorated buildings. For TDR evaluation, thermo-graphic camera was used to measure and analyze the surface temperature of external wall. Also, dew condensation evaluation was analyzed using the Temperature Difference Ratio Inside(TDRi). Result: As a result of analyzing thermal performance through TDRo, the first decline point of thermal insulation performance began after 14-16 years have passed since construction was completed, and after 20 years have passed the decline point of thermal insulation performance reappeared. As a result of analyzing U-value with HFM measurement method, the decline rate of external wall's thermal insulation performance is lower than 2% in average at around 5 years after completion, and 8.7% in average at 10-15 years, and over 10.2% in average at 20 years.

Furniture in the modern living environment, inclusive the importance of its practical value, is a plastic element of indoor space, and its artistic value also holds an important position. Moreover, emotional design based on the emotional engineering in a structural change of modern society such as urbanization, small family, aging society is proposed as an important keyword in the modern design. Namely, furniture as an component of modern residential space has been advanced as a human-oriented environmental element considering people's emotional and mental value to the functional satisfaction and artistic and emotional satisfaction. Furniture is a living tool that is much contacted to people, which affects highly on people's body and mind. This means that people's volition action can be naturally induced by furniture design, and that furniture can display a role as an active tool of means to make people's interpersonal communication and interchange. Namely, I think furniture design of emotional interchange that understands furniture user's pattern behavior and pattern, and observes furniture form and structure and functionality on users' relationship affecting on people's emotional stability and interpersonal interchange of emotion, as an indispensable element necessary for producing more human and prosperous environment of life.

In this study, we investigated the characteristic of volatile organic compounds (VOCs) concentrations in Shiwha area, which were measured using the Open-path FTIR Gas Analyzer. The passive samplers were set for a certain period of time to obtain the average concentration of toluene, ethylbenzene, o-xylene and styrene. In addition, VOCs concentration contour maps were constructed using the Tecplot program to illustrate the VOCs concentration distribution. The residential area showed higher concentrations than the industrial area. And the summer had higher concentration value than the winter. Also, we confirmed that the VOCs concentrations ranged from 2 to several tens ppb in the vicinity of an industry than diffused VOC concentration, whereas those ranged from 0 to 5 ppb in most other areas. It was conferred that the wind change with seasons significantly affects the distribution of VOCs concentrations such as a northwesterly wind in the winter or a southwestern wind in the summer.
