In order to improve the housing environment and quality of life for the rural elderly, this study aims to identify and present the status of community centers, most widely used by the elderly in rural areas. Through the literature review, type and space elements of community centers were derived and selected three target areas were investigated. As a result of literature analysis, the space type of rural community centers were classified as indoor space and outdoor space. The indoor space types were classified as entry space, public space, sanitary space and the outdoor space were classified as entry space and leisure space. Some community centers were surveyed in Seocheon-gun, Wanju-gun, and Cheongju-city. Results indicate the indoor and outdoor space design and elements were undergoing a lot of inconvenience partly because standard design was considered and the space was not planned for the physical, psychological and social health of the rural elderly. Therefore, this study will be used as a basis for building healthier and more friendly residential environments that can enhance the health and quality of life for the elderly in rural areas.

이 연구의 목적은 카를로 몰리노(1905~1973)의 복합적인 특징을 그의 초현실적 공간구성 방식을 특별히 고려하여 분석하는 것에 있다. 몰리노는 가장 독창적인 현대 이탈리아 건축가들 중 한 명이다. 그는 생애동안 그의 작품들은 비평가들에게는 인정을 받지 못했다. 그의 반 순응적인 성격과 극심한 개인주의도 일조를 하였지만 가장 큰 이유는 그의 작품들이 그의 전문적인 활동과 다양한 개인적인 관심사 사이에서의 강박적인 상호작용에 기반을 두었기 때문이다. 그의 독창성은 그의 능력에 있는 것으로, 항공학, 자동차, 스키, 무대 디자인, 패션, 예로티즘, 문학 그리고 그 외 수많은 다양한 분야에서 얻었던 지식을 디자인하고 건축으로 변형하려는 그의 초현실주의 배경에서부터 나온다. 개인적인 집착으로 그의 작품을 키워가면서 몰리노는 당시 현대 건축의 모든 관습들을 깨고 전문적인 능숙함과 독특한 예술적 시야 사이에 걸려있는 독특한 디자인 표현을 보여주었다. 이 연구는 몰리노의 독특한 공간 구성 방식을 벗겨내기 위해 그의 배경, 즉 그가 열정적으로 탐구했던 연구 분야들과 전문적인 생산물 사이의 연결고리를 분석한다.

This study was conducted to investigate the efficiency of the filtering sets composed of fiberboards, which were fabricated with lignocellulosic fiber and cork oak bark-based activated carbon (COA), as well as traditional Korean paper handmade from mulberry trees (KP) for the filtration of PM, TVOC and HCHO. Three-layers fiberboards (WRF) were fabricated with wood fiber in its surface layers and recycled fiber/COA in its core layer using a protein-based adhesive with the resin content of 8%. Filtering sets were composed of three WRF and one sheet of KP. Concentrations of PM, TVOC and HCHO generated with the combustion of a incense in a sealed laboratory hood were reduced efficiently with the operation of air-purifier installed the filtering sets. Except for the WRF fabricated with 4%/4% resin contents, other WRF were prepared with 5%/3% and 6%/2% resin contents in surface/core layers, and then the WRF were used with KP for the fabrication of filtering sets. Filtration efficiency of the filtering sets was improved as the core-layer resin content applied in the fabrication of WRF decreased. In addition, filtration efficiency of the WRF-based filtering set fabricated with KP of 25 g/m² basis weight was higher than that with KP of 45 g/m² basis weight. Filtering sets composed of three-layers fiberboards (RWF) that recycled fiber and wood fiber/COA were used in its surface and core layers, respectively, and KP-25g showed higher filtration efficiency than those of WRF-based filtering sets. Air-inhalation equipment installed the RWF-based, WRF-based filtering sets and without filtering set were operated in small indoor and large outdoor spaces. Efficiency for filtering PM and TVOC of the RWF-based filtering sets was higher than that of other filtering sets. It is concluded that fiberboard-based filtering sets composed of RWF and KP-25g can be used as a filter for reducing the concentrations of PM and TVOC existed in indoor and outdoor spaces.

Recently, the proportion of single-person households is on the increase in Korea, expected to reach 34.6% in 2035. Among the single-person households, Young single family households are facing greater difficulties due to high house prices in Korea. The government is expanding its support to Young single family, executing various policies such as public lease housings, private lease housings for youth, youth dormitory, etc. The purpose of this study is to understand the exact housing requirement of Young single family households who have different lifestyles with other age groups and provide base line data for youth house planning which will be in use later on. Study methods are shown below. First, this research studied the status and characteristics of Young single family households by looking into literature. Second, by studying previous studies concerned with life style and housing preferences of youth, the tool for investigating preferences and needs of housing environment by Young single family households was composed. Third, survey on characterstics of space usage, preferences and needs on flat composition, and preferences of interior design were conducted based on lifestyle of Young single family-households. The survey was conducted as an online survey using SNS for 150 Young single family holds from the age of 20 and 39, including students and office workers from December 2018 to January 2019. The results are as following. (1) Looking into the space usage characteristics, considering that various activities other than basic functions take place in bedroom and living room of small-sized Young single family households, we need to consider this additionally when planning the housing. (2) Looking into the preferences and composite needs of flat composition, the subjects demand separate bed room and more living room space, and also demand expansion of living room space where various activities take place and additional storage such as dress room in bed room (3) The preferences toward interior design show preferences toward modern style and achromatic color, a representative color. The subjects also prefer floor finishing materials normally used for living spaces, and indirect, soft lighting that uses wall. Also, there are differences between interior design preferences between students (20's) and office workers(30's) due to their different lifestyles. Research is needed to propose practical residential environment requirements and plans through a case study of actual public rental housing and a wider range of users.
