Minerals play important roles in biological processes. Hair mineral analysis has the advantages of conveniences in sampling and observing the profiles of multiple minerals simultaneously. The purpose of this study was to compare hair mineral contents between urban and local middle school students, and to find out the relation with nutrient intakes and clinical symptoms. Ten nutritional minerals and 7 environmental mineral contents were analyzed in the hair samples of 44 and 37 male students who resided in urban and local area, respectively. And their nutrient intake and clinical symptom score were estimated from questionnaire. The average age, height, and weight were 15.1 years, 168.4 cm, 56.8 kg in urban subjects and 15.4 years, 169.1 cm, 61.9 kg in local subjects, respectively. The residence types were apartment (63.6%) and small-sized apartment (22.7%) in urban subjects and apartment (51.4%) and house (37.8%) in local subjects. The primary water sources were purified water (38.3%), running water (18.2%) in urban subjects and purified water (32.4%), underground water (27.0%) in local subjects, respectively. Daily energy and nutrient intakes were not significantly different between two groups. Among the surveyed 17 clinical symptoms, the scores of constipation, cold, anxieties and total score of clinical symptoms in urban subjects were significantly love. than those in local subjects. Hair contents of Na, Mg, Ca, Cu, V Al, As were significantly higher, while U was lower in urban subjects compared to those in rural subjects. Hair contents of Ni and U were significantly correlated with food intake, and Cr, V, Al, Sb, As, U showed a correlation with energy intake. Hair Mg level showed significantly negative correlation with total clinical symptom score. In conclusion, hair mineral profile between urban and local students was significantly different. And some of these minerals were significantly correlated with food and nutrient intakes. Especially hair magnesium was significantly correlated with total clinical symptom score. Therefore, hair mineral levels would be needed for more systematic study elucidating potentiality as a useful clinical tool.

세계적인 기후변화 영향은 한반도의 강우패턴 변화와 그로 인한 홍수와 폭설, 가뭄 등의 급격한 기상이변으로 나타나고 있다. 이에 국내외적으로 기후변화대응 관련 다양한 대안이 검토되고 있으며, 선진외국에서는 10여 년 전부터 저영향개발(LID)을 통한 수자원의 활용과 환경 친화적인 개발에 관심을 기울이고 있다. 국내에서도 일부 개발 사업에 LID 기법을 적용하는 계획을 추진하고 있으며, 관련 기술의 연구개발이 진행 중이다. 그러나 민간이 손쉽게 활용할 수 있는 제도 및 기술이전이 부족한 실정이며, LID 요소기술의 실효성 또한 충분히 합의되지 못한 현실이다. 이에 LID 요소기술 중 공동주택단지에 적용하기 용이한 요소기술을 분류하고, 그 중 침투기능을 수행하는 요소기술을 대상으로 공동주택단지 조경공간에 적용하고, 물순환 모의(SWMM 5.0)를 시행하고, 기술의 실효성을 검증하였다. 이를 위하여 각기 다른 지역의 공동주택단지 3개소를 대상으로 미국 EPA의 SWMM 5.0을 활용한 강우모의를 실시하고, LID기법 적용 전, 후의 물순환 모의(침투량, 지표증발량, 지표유출량)를 실시하였다. 녹지공간에서 LID 기술의 중요성은 빗물의 양적 질적 조절과 공동주택단지의 Amenity를 증진 시키는 역할이다. 공동주택단지의 물리적 한계를 이해하고 원활한 수순환 계통의 적용을 위하여 LID 통합관리기술(IMPs)을 적용해야 하며, 이를 위하여 조경, 건축, 토목, 환경전문가간의 저영향개발에 대한 기술적 통섭의 노력이 요구된다.

국내의 주택 부족 문제가 해소되면서 공동주택 건설시장이 고품질을 원하는 소비자 위주의 시장으로 변화되었고, 마감 품질에 대한 기대가 높아졌다. 한국토지주택공사가 공급한 공동주택의 하자 민원 발생 접수 현황에 따르면, 타일 관련 민원이 가장 많이 발생하였다. 이와 관련된 하자 민원을 줄이기 위해 국토교통부에서는 「공동주택 하자의 조사, 보수 비용 산정 및 하자판정기준」 개정안을 입안하는 등 지속적인 노력을 하고 있으나, 예방적 처리 방안에 대한 마련은 미흡한 실정이었다. 또한, 국내·외 선행연구를 살펴보며 전문가의 정성적 지식이 반영된 타일공사 하자 유형 특징을 도출한 후 분류 체계를 구성하고, 유형별 원인에 따른 대책을 제시하는 연구가 부족하였다. 따라서 본 연구는 정성적 지식을 반영할 수 있으며 다양한 지표와 하자 유형 간 관계 파악이 용이한 AHP 분석 기법을 활용해 건설 전문가에게 설문조사를 실시한 후, 도출된 두 가지 정성적 지표인 '하자 보수 후 재발 가능성', '하자 보수의 어려움 정도'의 가중치와 정량적 지표인 '하자 발생빈도'를 방사형 그래프로 시각화하여 타일공사 하자 유형의 특징을 분석하고 원인에 따른 저감 대책을 수립한다. 이는 거주환경의 품질을 높일 뿐만 아니라 공동주택 타일공사의 원활한 하자 관리를 위한 시스템 구축 및 공동주택 타일공사 하자 저감에 기여할 것이다.

This paper reports on tests of reinforced concrete shear walls for wall-type apartment structure under axial loads and the cyclic reversal of lateral loads with different confinement of the boundary elements. Confinement of the extreme element by U-stirrups and tie hooks seems to be as effective as closed stirrups. The shear strength capacity seems not to be increased by the confinement but deformation capacity improved.

Window system is an essential component for ventilation, lighting, and thermal environment in buildings. However, window system has the lowest insulation performance and may cause high energy consumptions, if it is not properly designed. Thus, performance of window systems play an important role in built environment. This study proposes a new window systems for balcony, which has double vents and analyses the thermal performance using an intergrated simulation method with Therm 6.1 and Widow 6.1. The result shows higher U-factor than conventional window systems. It is expected that the double vent window system can increase thermal performance and save energy in apartment houses.

Building components have been deteriorated by various factors such as location, a building type, a surrounding environment and so on. In addition, each component has a peculiar characteristics, compared with other components in properties of matter an used part. Building components would be required to maintain its function and performance to provide the resident with a decent living condition. It is important to decide the repair time, scope and a required cost in repair plan, considering the each component's characteristics. In this parer, it aimed at providing the economic repair pattern to analyze the relation of the time-elapse and the cumulative repair cost in the apartment housing using 3rd quadratic function. Results of the study are as follows: First, the shape of the function for the economic repair is classified into two type. One is the continuous increase type of the cumulative cost which properly means the iterative repair type after built. The other is that the function has the maximum state at a point which means one-repair after its repair would be delayed to a scheduled time. Second, the iterative repair pattern would include window, roof proof, lighting and water supply pipe. The other repair pattern would include the paintings, heating pipe and sign board.

In order to handle the crisis about energy-environment problem, it is necessary to develop the future-oriented and innovative energy technology in architecture area. So the development of new technology for energy saving and alternative energy use has been spurred in this area. Double skin window system, which is an active covering to respond to the exterior change of the environment, is the skill that can reduce the indoor cooling and heating load and the environmental architecture can be realized. This study works out U-value of windows using the window-simulation program with the development and study of the double skin. In addition, the effect of the double skin insulation on the efficiency rating has been analyzed, applying to the certification system of the building energy efficiency rating which has implemented.

The environment is the important resource to use as well as to conserve for the development. Since 1990s, it has accentuated the importance of the environment and tried to conserve the environment in many areas. Among many area, the building industry has played a role to destruct the environment for providing the living decent space and brought the environmental affect. Therefore, the building industry should endeavor to mitigate the environmental affect. In building life cycle, it consumes the energy and natural resources. But it is difficult to evaluate the environmental affect during the whole building life. It is impossible to calculate the environmental affect without the much time and effort. Therefore. it requires the easy and handing program to calculate the affect to environment in each building life cycle. Until now, many program for assessing the affect to the environment have been developed and limitedly used because of the assessment scope and contents. In this paper, it aimed at developing the assessment program of LCA, focused on the energy consumption and carbon-dioxide emission compared with the domestic and foreign concerned programs. The developed program is divided into 3 areas; construction, maintenance, demolition.

Apartment balcony has been indiscreetly remodeled since the government permitted remodeling on January 2006. But remodeled balcony has a few problems such as increase of heating energy, surface condensation and cold draft. The reason of thermal problem is mainly caused by the window system in a extended balcony. The purpose of this study is to analyze heating and cooling energy and propose the efficient window types for the extended balcony area of a apartment building. 4 types of window system which have fairly high U value in Korea are investigated as follows ; double clear glass, double low-e glass, triple clear glass and triple low-e glass. Comparing double clear 91ass with double low-e glass, triple clear glass and triple low-e glass, simulation results show that 10%, 7% and 15% saving of total primary energy can be expected.
