스마트 윈도우는 건물의 에너지 절감을 실현할 수 있는 신소재 건축 자재이며, 상황에 따라 가시광선 투과율(Visible Light Transmittance), 일사획득계수(Solar Heat Gain Coefficient, g-value)를 자유롭게 조절할 수 있는 특징을 가진다. Electrochromic(EC), Suspended Particle Device(SPD), Polymer Dispersed Liquid Crystal(PDLC) 등이 스마트 윈도우에 해당되며 현재 실용화 단계에 있다. 최근 스마트 윈도우의 VLT 및 g-value 조절 기능을 통해 건축물의 에너지를 절감하는 방법에 대한 연구가 활발하게 진행되고 있으며, 일부 유의미한 결과가 도출되고 있다. 하지만, 건축물의 에너지 절감에 대해서 연구의 영역이 제한되어 있고, 실내 환경에 대한 연구는 다소 부족한 실정이다. 에너지 절감에만 초점을 맞춘 실내 공간은 충분한 쾌적성이 확보되지 않기 때문에 실내 환경에 대한 고려가 요구된다. 따라서 이 연구에서는 사무공간을 기준으로 채광성능(Daylight Performance) 분석이 수행되었다. 세계 각 국의 친환경 건축인증제도인 LEED, BREEAM, CASBEE, G-SEED의 기준을 통해 스마트 윈도우의 VLT 조절에 따른 채광성능 검토가 이루어졌으며, 쾌적한 실내 채광환경을 유지할 수 있는 스마트 윈도우의 VLT 범위에 대한 고찰이 이루어졌다. 분석을 위해 사용된 스마트 윈도우는 VLT 조절 범위가 가장 넓은 EC가 사용되었다. 분석 결과 한국의 친환경 건축인증제도인 G-SEED의 평균주광률을 충족하기 위한 스마트 윈도우의 최소 VLT는 25% 이상으로 나타났으며, 스마트 윈도우의 VLT 조절은 균제도에 유의한 영향을 미치지 않는 것으로 나타났다. 또한, LEED의 실내 최소조도의 기준을 적용할 시 적용되어야 하는 계절 및 향에 대한 스마트 윈도우의 VLT 조절 범위 값이 도출되었다.

본 연구는 상업공간에 환경적 자극으로 설치된 미술품 색 계열이 방문객의 만족도에 미치는 영향과 그 영향 관계의 조절효과를 분석하고자 하였다. 이를 위해 환경 심리학 분야의 매장환경 연구에 적용된 자극(Stimulate).유기체(Organism).행동 반응(Response)의 SOR 모형과 이를 이용한 선행연구를 토대로 미술품 색 계열(S) .기분 및 공간 어메니티(O).만족도(R)의 연구 프레임워크를 개발하였다. 실험은 미술품의 색 계열에 대해 난색과 한색이 설치된 이미지를 제작하여 두 집단 간 응답자가 반응하는 만족도 차이를 조사했다. 회귀분석을 통해 검증한 결과 미술품 색계열은 난색(vs. 한색)이 설치된 경우 더 높은 방문객의 만족도를 유도한다는 것을 발견했다. 또한, 이러한 영향 관계에 있어서 기분과 공간 어메니티 유형의 조절요인을 분석한 결과 미술품 색 계열의 난색(vs. 한색)이 주는 긍정적 기분을 평균보다 더 높게 느꼈을 때, 공간 어메니티의 네 가지 유형 중 쾌적성과 심미성만을 더 높게 인지했을 때 각각 유의한 조절효과가 나타난다는 것을 발견했다. 본 연구 결과는 상업공간의 물리적 환경을 자극하는 미술품의 난색 계열이 한색 계열에 비해 방문객의 만족도에 더 긍정적인 영향을 미치고, 이것은 긍정적 기분 및 쾌적성, 심미성에 따라 강화된다는 것을 증명함으로써 기존 문헌의 이해를 추가하고 효과적인 마케팅 전략에 유용한 시사점을 제공한다.

This study investigates the effects of seat-design elements such as seating arrangement, shape, and height on speech privacy in high-speed trains. For the evaluation of speech privacy, acoustic simulation software was used to reproduce room acoustical conditions in passenger cars on the basis of in-situ measurement data. The influences of speech source directivity and source height on privacy distance ($r_P$) were investigated, and it was found that $r_P$ determined using an omni-directional source was relatively shorter than that determined using a directional source. It was also found that $r_P$ decreased when the source height was lower than the height of the seat-back because the seat-back blocked the propagation of speech from the sound source. The effect of seating arrangement was not significant when comparing the vis-a-vis seating and one-side seating arrangements. In addition, among the alternative seat-designs, the seats that block the space between the seats and cover the space near the ear were found to show significantly enhanced speech privacy in high-speed train passenger cars.

Survey question asked for the general features of the staffs, satisfaction, dissatisfactory spaces and the reasons about dissatisfaction of the elderly with dementia. The data were analyzed using the frequency, percentage, crosstab, paired t-test with SPSS 11 program. The result of this study was as follows. First, most of the elderly with dementia were unsatisfied with their bedrooms and bathrooms in bedrooms. Second, the unsatisfied spaces among the living environment were bedroom, bathroom in bedroom, dining room, day corner, special activity room, common bathroom with mechanical bath, and dressing room. The reasons of the unsatisfied spaces were size, comfort, non-existence of the space, and noise in the space.

This study was carried out to develop a new application field of traditional Hanji and obtain the basic data for producing functional Hanji using sawdust ceramics and rice-husk ceramics as an architectural material. The results measuring water vapor permeance and water vapor absorption for using window materials and wallpapers are as follows. Hanji wallpaper has good things in controlling indoor space comfortably. Particularly, ability of controlling humidity of Hanji wallpaper affects indoor space comfort and human health. In the case indoor humidity is higher than outdoor humidity, according to the addition of ceramics, Hanji wallpapers maintain the humidity by retaining water vapor molecules in the pores of ceramics. Thus the Hanji wallpapers with ceramics, in particular rice-husk ceramics, make it superior to non-ceramics Hanji wallpapers in maintaining the humidity indoors.

The Homeshare Program was promoted to solve the housing problems of the elderly and the young by the Seoul City in 2012. The elderly can provide spare rooms in their homes for the young at low rental fees, and the young can provide daily services to the elderly, cooperating with each other for better housing and life. The aim of this research is to find out how the participants use the shared space and what kinds of activities are shared in homeshare. This research uses case studies, which interviews 10 cases of homeshare in Seoul. The contents of the research are investigated shared spaces of the elderly, and analyzed contents of interaction lives in shared spaces. The elderly experience loneliness while living alone, and having someone to live with gives them comfort and a sense of security, and this is one motive for participating in homeshare. The elderly and the young share many equipment and shared activities and interactions in shared space. The homeshare program makes it possible for the elderly to aging in place and have interactive relationships with different generations. Therefore, homeshare may the formation of a new family, and new dwelling utilizing the elderly's house.

To create urban landscapes that take human emotion into consideration, the present study verified the psychological effects of artificial waterscape facilities on users, as these facilities significantly impact their psychological comfort. Data was collected using the SD scales and POMS of 60 male and 60 female participants after they watched a video of four waterscape facilities. Participants deemed the video clip of a fountain waterscape to be artificial and linked it with changeable images that increased their vigor. The video clip of waterfall stimulated various impressions (e.g., vital, liked, active, etc.) and changed participant' mood states by increasing their vigor and decreasing fatigue. The video clip of the pond yielded familiar impressions, produced less free images, and decreased tension among participants. Finally, the video clip of the stream stimulated quiet and comfortable images as well as reduced negative feelings of anger, confusion, and depression among participants. Furthermore, males experienced more positive effects than females, regardless of the type of waterscape facility. The study findings indicate that the four different waterscape facilities influenced participants' mood states. Additionally, the psychological effects differed by gender. The data suggest that landscape planners need to carefully consider their choice of waterscape facility when designing green spaces to ensure that the space is psychologically comforting to users.
