In this study, the usage status and satisfaction of the ventilation system installed in apartment houses of Seoul were investigated for 200 households. The summary of that study result is shown as follows: In the survey, approximately more than 20% of the residents in apartment houses were not aware of the installation of the ventilation system. Meanwhile, even in the residents who were aware that the ventilation system is installed, approximately more than 35% answered that they were not using it at all. The reason was their ignorance about how to use the ventilation system. Also, it showed that approximately more than 75% of the residents didn"t perform maintenance of the ventilation system such as cleaning, etc. Besides, in order to enhance the ventilation system in apartment houses, preparation of manuals about usage, and cleaning method (37.58%), and publicity and instruction on the ventilation system in moving in (29.3%) are necessary. On the analysis of satisfaction on the ventilation system, age, gender, period of residence, and number of residence were found to be irrelevant to the characteristics of the respondents. Also, the respondents answered that the difference in each ventilation system such as ceiling & floor type was irrelevant to the satisfaction. For the ventilation system improvement criteria, maintenance (filtering and cleaning, 46.88%) and cleanliness (21.88%) were found to be priority.

We measured the temperature of target surface inducing by various physical phenomenon on magnetron sputtering target and confirmed the possibilities if the temperature distribution could affect plasma and deposited thin film. The target of magnetron sputtering has two types: round type and rectangular type. In a rectangular target, the concentrated discharge area by corner effect by magnetic field and non-uniform erosion of target are generated. And we found the generation of non-uniform temperature distribution on the target surface from this. This area was $10{\sim}20^{\circ}C$ higher than non-sputtering area. And if particles are generated during sputtering process, they were $20^{\circ}C$ higher than the area where is higher than non-sputtering area. These effects result in non-uniformity of thin films, crack of ceramic target, and shortening target life by non-uniform erosion. 마그네트론 타겟에서 일어나는 다양한 물리적 현상에 의한 결과로 인해 발생하는 타겟 표면의 온도를 측정함으로써 그 분포가 플라즈마, 혹은 증착되는 박막에 영향을 줄 수 있는 가능성을 분석하였다. 마그네트론 스퍼터링의 타겟은 크게 원형 타겟과 사각 타겟으로 구분되는데, 사각 타겟에서는 자기장에 의한 corner effect 등에 의해 전자 집중 방전 영역이 발생하고 그것에 의해 타겟 표면에서 불균일한 온도분포가 생성됨을 확인했다. 국부적으로 온도가 높게 올라가는 지역은 비스퍼터링 지역에 비해 $10{\sim}20^{\circ}C$ 정도 높았으며, 스퍼터링 공정 시 문제점 중에 하나인 particle이 발생하면 그 부분에서 온도가 $20^{\circ}C$ 정도 더 상승함을 알 수 있었다. 이런 영향은 증착되는 박막의 균일도에도 적지 않은 영향을 주었으며 세라믹 타겟의 경우, 균열의 원인이 될 수 있고, 불균일한 타겟 침식으로 타겟의 수명을 단축시키는 문제를 유발하기도 한다.

The goal of this study was to test the application of a wind power system with combined exhaust to a super high-rise apartment, and the research results can be summarized as follows. 1) The proposed location of the applied wind power system with combined exhaust in the study was a rooftop exhaust pipe from a dining room and bathroom of a super high-rise apartment. At that time, the size of the module for concentrating wind was 500mm in diameter and 320mm in height (upper diameter was 400mm with Venturi effect inducement). Blade was combined Savonius style and Darius style, able to rotate. 2) In the results of measuring the generation quantity for 14 days by installing the wind power system with combined exhaust at an apartment rooftop with 35m height, the case 3 system (outside air + exhaust wind + wind concentrating device) proposed in the study appeared to have a higher generation quantity than other systems. Specifically, even when there was a low outside wind velocity value, the electrical energy appeared to be high, confirming the exhaust wind concentration effect.

The goal of this study is to retrofit the windows of residential buildings and to activate the green remodeling by verifying energy saving and indoor thermal environment. As a result of analysis of the energy saving effect of 458 units window retrofits, it was possible to reduce the energy requirement by 48.20% ~ 54.97%. According to the improvement on indoor environment, it was possible to operate by reducing heating temperature and supply time. The actual gas consumption of the heating period was reduced by 25% compared with that of the window retarder to save 28,968 thousand won of heating energy cost. Resident’s satisfaction surveys were conducted one year after window retrofit. More than 80% of the respondents answered that they satisfied the improvement on window performance, indoor thermal environment and indoor sound environment. As a result, we verified the energy saving effect and the improvement on the indoor environment through window retrofits.

The purpose of this study is to review all phases of the pilot project through the implementation of the Green Remodeling process. The Green Remodeling process was developed to facilitate anyone’s ease of use. The Green Remodeling process consists of five phases : project, plan, design, construction, operation and maintenance. Each stage simulation was performed and the energy saving was predicted. Architects can easily obtain energy information of a building. In this study, we propose a green remodeling proposal plan through pilot project. Ultimately, the spread of green remodeling will greatly contribute to achieving the goal of reducing greenhouse gas emissions.

Therefore Small Wind Power System combined exhaust as measures to solve these problem. The purpose of this study is increase the effect of small wind power systems with exhaust apply for inflow module to solve these problem. For this, through CFD simulations are use to evaluate inflow module. Results from the study can be summarized as follows; the inflow module can increase exhaust air speed and generation. So inflow module is better than normal exhaust pipe.
