우리의 식생활 및 주거 환경이 향상됨에 따라 과거에 비해 학생들의 체격이 커지고 체형 또한 점차 서구화 되가는 경향을 보이고 있으나 아직까지도 초${\cdot}$중${\cdot}$고등학교에서는 학생 자신의 체격에 적합하게 조절하여 사용할 수 없는 고정형 의자를 사용하고 있다. 이에 따라 학생들의 신체발육에 지장을 초래 할 수 있으며 특히 요통과 같은 허리에 문제를 일으킬 수 있다. 따라서 본 연구에서는 학생 자신의 체격에 맞게 높낮이를 자유롭게 조절하여 사용할 수 있는 학생용 의자를 개발하였다. 개발된 조절형 의자는 일반적으로 사용하는 학생용 의자의 다리부분에 풀림과 조임이 가능한 금속제 나사형식의 높이조절봉을 도입하여 공구가 필요 없이 손으로 회전시켜 좌판의 높이를 자유롭게 조절하여 사용할 수 있게 설계하였다. 또한 의자 등받이는 전${\cdot}$후${\cdot}$상${\cdot}$하방향으로 이동되게 함으로써 착석 시 좌판의 깊이와 등받이의 높낮이를 동시에 한번의 동작으로 조절 가능하게 하였다. 한편 개발된 조절형 의자는 현재 우리나라에서 채택하여 사용하고 있는 ISO 5970(Standards for tables and chairs for educational institutions)과 비교하여 수용능력에 따른 적합성 여부를 평가하였으며 피실험자 40명을 대상으로 fitting trials를 실시하였다. 평가결과 개발된 조절형 의자는 두가지 평가 기준에 적합하였으며 실용화 가능성을 발견하였다. 향후 이를 각급 학교 및 학원에 보급 활용함으로써 학생들의 이상체형 형성을 억제하여 신체 발육과 안전을 도모할 수 있으며 학습효과 또한 높일 수 있다고 판단된다.

This qualitative research was designed to explore the use of housing among Korean Chinese people in Harbin, China. Focusing on the use which based on the epistemology of housing adjustment, this was particularly designed to examine its cultural assimilation and acculturation on the way of life course, it employed the in-depth interview on the oral history of 5 interviewees in their 60s and 70s, individualized interviews were conducted from May 28 to 31 in 2010. Key findings were summarized as follows; 1. The free market reform in China resulted in privatization that allowed respondents to become homeowners, and the ownership was viewed as part of family asset centered upon a sense of solidarity. 2. Although homeowners in multi-story houses were responsible to decorate interior spaces, the common features in using interior spaces were found: entrance had no thresholds; kitchen was small, lack of storage cabinets, tile-flooring; washers were installed inside bathroom; and newly built apartment didn't have proper space to store Korean fermented foods. It was observed that housing adaptation outweighed housing adjustment. Those who used to live in Chinese houses with indoor-wearing-shoes or Russian houses with indoor-wearing-slippers were receptive to the use of dining table and bed, and the community heating system discouraged the use of individual electric water heater because of high electricity cost. 3. In daily life, eating habit wasn't much changed to the Chinese style, meals were shared, dish sterilizer was popular, and Kimchi fridge wasn't used. Because of the influence of the Chinese culture, such Korean traditions as ancestral rites and bedroom allocation tradition faded away, but traditional family values remained unchanged. In conclusion, Korean Chinese people experience normative housing deficits and adaptation selectively incurred. It's implied that residential design meets the needs resulting from the dual culture in terms of cultural assimilation and acculturation.

This study aims to examine the traditional living space to reflect the environment-friendly design methods and principles of reestablishment. To do so, this study carried on a related literature study and field survey. The traditional living space in terms of the environmental friendliness is reflected on site selection and space composition, and utilization of natural energy and natural materials. Focused on the Kwangajeong in Yangdong Village, this study is to identify eco-friendly techniques on the traditional living space. As a result, it shows that Kwangajeong with the side of the southeast in site selection had been considered in aspect of environmental control such as sunshine and solar radiation. Also building construction techniques had been used to minimize the variation of terrain. In aspect of environmental conservation, Kwangajeong had structurally arranged the gate, an inner yard and an inner floor to allow good ventilation. In aspect of space composition, Kwangajeong with the emphasis of scenic view had utilized the methods that attract external landscape through the control of its fences. Environment-friendly techniques and control principles in traditional space had been developed by a long experience through the long periods and the traditional techniques suitable for local climate and local environment have been developed. The technical development of these techniques to resolve the global environmental and energy issues and create a more pleasant living environment of human beings might be critical.

The rapid urbanization after 1970s caused the shortage of dwellings in urban areas. As the result, the underground dwellings were developed to compensate for the insufficient dwelling spaces. While the underground dwellings have some advantage in the respect of thermal and acoustic environment, they usually have the basic problems in the indoor air quality because of the lack of natural ventilation through small window areas. The purpose of this study is to investigate and to improve the indoor air quality of underground dwellings. Thirty Units in Seoul and Gyung-Gi Province were investigated into the indoor environmental conditions. For the purpose of the improvement of their indoor air quality, Automatically-operated ventilating fan was installed in a sample unit which has worst indoor environmental condition. Then the indoor air quality was monitored when it was operated by $CO_2$ control system and timer. Finally economic feasibility study was made considering the effect of the improvement of indoor air quality. The extra cost for installing timer could be paid back only in 10 months, so timer-installed automatic fan is recommended to improve the indoor air quality of underground dwellings.

This study aims to analyze the housing satisfaction of 55 years and older (55+) single-person householders in U.S. urban communities with the 2011 American Housing Survey Data. Single-person householders younger than 55 years of age (55-) were used as a reference group. Housing Adjustment Theory was used to develop a research framework to depict the relationships of housing satisfaction (dependent variable) with demographic and housing variables (independent variables). The regression analysis revealed that age, health status, government income, race, gender, age of house, housing quality, neighborhood, structure type, and tenure status had a significant effect on housing satisfaction levels of both those aged 55- and 55+. However, for the cohort of 55+, education, census region, housing affordability, and structure size also affected their housing satisfaction. Neighborhood satisfaction had the strongest effect on housing satisfaction of both groups. These variables were discussed in terms of resources and constraints contributing to their housing satisfaction. This study highlights the present and future housing trends and challenges of U.S. single householders in U.S. urban communities.
