The aim of this study is to investigate and to analyze the reverberation times of apartment houses Measurements were conducted in a total of 44 rooms(36 rooms were in occupied houses and 8 rooms were in unoccupied houses) according to KS F 2864. The results showed that the averaged reverberation time of the occupied and the unoccupied houses were about 0.3$\sim$0.5sec and 1.2$\sim$l.5 sec, respectively, at 500Hz octave band frequency. And the averaged absorbtion coefficient of the occupied and the unoccupied houses were about 0.13$\sim$0.35 and 0.11$\sim$0.20, respectively. In addition, We verified that the reverberation time generally depended on the frequency; the lower the frequency, the higher the reverberation time.

The aim of this study is to improve the "empty house problem" in Korea. The direction of improvement of systems in Korea was considered and compared with empty house systems in the United Kingdom, France, Germany, the United States, and Japan. Korea's system is based on comprehensive regulations centered on the demolition of empty houses. To actively solve the problem of unoccupied houses, detailed guidelines are needed, which must consider the current status and surrounding environment of empty houses. There should be institutional grounds for local governments to actively intervene in the issue of empty houses, and there should be a system that enables tax and cost support for the reuse of such houses. An information sharing system is also needed for sharing empty house information among local governments. To utilize empty houses as resources for the housing market, it is necessary to establish a consultative system consisting of residents, urban and architectural experts, and private businesses.

Short-term tests were conducted on a house at KIER, Daejon for its thermal performance evaluation. The test procedure and data analysis were made according to the PSTAR method. Each test period was 3 days during which the building was unoccupied. The data measured with 8 channels were used to renormalize an audit based simulation model of the house. The following are the key parameters obtained in the present analysis: 1) the building loss coefficient(skin conductance plus infiltration conductance during coheating period); 2) the effective building heat capacity; and 3) the effective solar gain. An estimation of total heat required to maintain a standard level of comfort during a typical winter season is also calculated on the basis of the renormalized simulation model and typical long term weather data.

The purpose of this study was to identify the design concepts embedded in our traditional interior space. The majority of this research was achieved through literature review as well as examining traditional Korean houses. The major findings were summarized as follows : First, traditional Korean interior space is contemplative. This is created possible by the careful placement of indispensable furnitures and accessaries resulting in an abundance of unoccupied space. Therefore, the room assumes a peaceful atmosphere which calms the mind and creates a tranquil setting. To enjoy the placidity of Korean interior space a humble demeanor and contemplative thought are required. Next, traditional Korean interior space is modest. This is created by the moderate proportions that do not challenge human scale. Traditional Korean interior space does not dominate its surroundings but rather conforms with them. This contrasts with traditional western houses which utilizes an overbearing scale sacrificing intimate space. Thirdly, traditional Korean interior space is raw. In other words, the materials used in house retain their self-evident natural state and are not artifically manipulated to hide their inherent properties. The fundamental conceptual belief that interior space should not defy nature but instead become part of it. Lastly, traditional Korean interior space is not decorative Rooms are not congested with frivolous aesthetics. Although this does not immediately attract the people's attention, eventually the interior space establishes a unique line of communication with them.

This paper presented an occupancy-based energy saving system for appliance energy saving in smart house. The developed system is composed of a sensing system and a home gateway system. The sensing system is set of wireless sensor nodes which have pyroelectric infrared (PIR) sensor to detect a motion of human and set of smart plugs which measure the current using CT (current transformer) sensor and send the current to home gateway wirelessly. We measured current consumption of appliances in real time using smart plugs, and checked the occupation of residents using occupancy sensors installed on the door and room. The proposed system saves electric energy to switch off the supply power of unnecessary usages in the unoccupied spaces. Experiments conducted have shown that electric energy usage of appliances can be saved about 34% checked by using occupation.

Since the beginning of the 90's, Fashion shows appear to be a type of performance form of art combining with other areas to visually entertain the viewers. This can be explained by the modern tendency to escape from society which requires formality and complicated lifestyles. Fashion shows take place in a scene Influenced by the idea of post-modernism which redefines the definition of space. A church, old factory, unoccupied ground, subway stations, or even place like a waste disposal are used as a setting. The stage set is no longer the T shape run way and the procinium arch has disappeared. The gap between audience and stage has diminished and theatrical element is added to the fashion performance by using viewers living and working environments as setting of the show. The human relation with machine based on the cutting edge technology such as the stage automation, robots and mist making sprinkler system introduces new elements with spontaneity and detailed planning in the stage performance. Music also plays an Important role in attracting viewers. The sound track covers house music to techno music. Instead of music being abstract, folks orchestral music, choirs, piano. even live concert performed by pop artist provide the liveliness of the fashion show. And the catwalk itself is a performance. Model needs to be well trained as the capable talent who can handle sensitive gestures, facial expressions, dancing and choreography. The improvisatorial interaction between audience and model lead to audience participation. Models now range from pop star, ordinary people, handicapped people, to elderly and so on. John Galliano introduced the theatrical factors for the fashion show and Alexander Mcqueen approached the fashion show as the visual art of communication. Hussein Chalayan utilized high technology skewing futurism as if in a magic show. Today the Fashion show tends to be a total performance which includes audience participation, impromptu, and that break the limitation that fashion shows previously had. This will lead the fashion industry in opening new horizon of its own.
