In recent years, many home machines have been developed in order to design and control comfortable interior inside houses. For such task, important factors are temperature, natural and interior lights, and space and control of relative factors each other. This paper presents novel sensor module inside houses, which is designed based on these factors through the PMV (Predicted Mean Vote) standard using information about home state. Moreover, LonWorks based power line communication technique is utilized for control interior lights and air-conditioners by means of wireless remote controllers. This mechanism is systemically operated via intelligent control framework.

대부분의 시간을 실내에서 보내는 사람들이 점점 많아짐에 따라서 안전한 실내 생활환경에 대한 관심이 높아지고 있고, 특히 실내 오염원을 감지하여 사전 조치를 취할 수 있는 측정 시스템에 대한 필요성이 점차 증대되고 있다. 이와 관련하여 본 논문에서는 다양한 환경 센서를 활용하여 가정이나 특정 실내공간의 환경정보를 측정하고 실내공기를 관리할 수 있는 '실내 환경정보 모니터링시스템'을 설계하고 구현하였다.

In contemporary times, "environmental designers" need to consider both exterior and interior aspects because of the growing trend in dissolution between exterior and interior spaces. To quantify "spatial sense" which serves as the standard for environmental design, this study has asked 63 subjects to evaluate 15 interior and 14 exterior spaces. The "spaciousness (small-large)", "openness(closed-open)", "warmness(warm-cold)", "brightness(bright-dark)", "softness(soft-hard)", "spatial intimacy" and "frequency of visit" were adopted as variables of spatial sense. Through the analysis of these variables, this study could gain the difference between spatial sense for exterior and interior environments, quantify the spatial sense that physically and psychologically appropriates to human beings. The result of this study can be summarized as follows: Twice the amount of spaciousness was observed between the interior and exterior spaces. And the standard on intimate space is established with W/H ratio of 5.71 and high Window/Wall Area ratio in the interior and an area of 3,800m2 and a W/H ratio of 5.57 in exterior. The difference between the spatial sense in the interior and exterior space is mostly dependent on the psychological sense. The increase of physical size caused by the interior space to be perceived as cold, dark and hard psychologically, but exterior space to be perceived as warm, bright and soft. Psychological senses, especially softness, affect spatial intimacy to the greatest extent among the given variables. As the psychological senses for interior spaces were largely independent from the given space's size and perceptive senses, the size of the interior space, which exhibited spatial intimacy, could not be deduced. In comparison to this, due to the high dependency between the psychological senses for exterior spaces and the given space's size and perceptive senses. The study also showed that interior and exterior spaces have relatively different spatial sense and physical standards. Such research results are predicted to provide applicable standards for environmental designers for exterior and interior spaces in the future.

In the interior lighting, usually we refer to TAL and general lighting. The last one is that we generally adopt it in the interior lighting conditions. Here, glare is most important factor of them, especially in working place using VDT. Reference or development of estimation on glare has been studied in CIE, IESNA etc. and these of glare regulations now are applied differently in the interior lighting design or estimation on glare. But we have no glare regulation in detail, of course except G classification, which has limit of itself, so in my case it is impossible to apply in the interior lighting. On this paper, with some of main glare regulations in the world and our conditions in the interior lighting which are selected carefully, in an actual state it has been estimated So, it intended to blow which one is most suitable or what factors are considered of them, also show glare index which are appropriate to our interior lighting.

Due to high density of population and progress of high building construction technologies, the number of high buildings has been increasing. Several information services have been provided to figure out complex indoor structures of building such as indoor navigations and indoor map services. The most fundamental information for these services are indoor network information. Indoor network in building provides topological connectivity between spaces unlike geometric information of buildings. In order to make indoor network information, we have to edit network manually or derive network properties based on the geometric data of buildings. This process is not easy for complex buildings. In this paper, we suggest a method to generate indoor network automatically based on crowdsourcing. From the collected individual trajectories, we derive indoor network information with crowdsourcing. We validate our method with a sample set of trajectory data and the result shows that our method is practical if the indoor positioning technology is reasonably accurate.

The purpose of this study is to provide fundamental cooling design data for the large public enclosures as gymnasium. This study executed indoor thermal environment verification of the existing gymnasium by measuring temperature distribution with cooling the space in summer. Cooling loads from human body was not considered. We examined various indoor thermal environment factors of the large enclosed space in this study which include vertical and horizontal temperature distribution, supply and return air flow feature, thermal comfort environment feature, amount of ventilation and etc.

The objectives of this study is to develop an adaptable digital wall model whose color can be changed dynamically according to the identified emotional state of a user. This study addresses how to capture a specific user's emotion through the web and use it for modifying VR model mainly for color adaptation. This adaptation process of a VR model consists of three phases: 1) identification of the user's emotional state projected onto the list of emotional keywords 2) translation of those captured emotional keywords into a pertinent set of color coordinations, and finally, 3) automated color adaptation process for the given model. This process derives an on-line viewer's emotional state, which can be utilized to find a new color scheme reflecting the identified emotion.

포름알데히드(HCHO)는 발암성 자극성 화학종으로 작업장과 실내공기오염의 중요한 오염물이다. 세계보건기구(WHO)에서는 30분 평균농도를 0.08ppm으로 설정하고 미국 산업 위생국(ACGIH)에서는 최대 노출 농도를 0.3ppm으로 규정하고 있다(Nakano and Nagashima, 1999). 또한 국내에서는 지하생활공간에서 포름알데히드 농도를 1시간 평균 0.1ppm 이하로 정하는 등 실내공간에서 포름알데히드 농도에 대한 관심이 고조되고 있는 실정이다. (중략)
