This study was carried out to find out the capability of applying such materials as porous concrete, could be called environmentally friendly materials, for bringing vegetations. For verying the purpose of the experiments such materials as potland cement and slag cement, coarse aggravates(${\phi}25mm$, ${\phi}18mm$, ${\phi}13mm$) were mixed. In the voids of porous concrete peatmoss and chemical fertilizers were filled, and on the surface of concrete organic soils were adhered for seeding grasses. For testing compressive strength, pH, voids the 12($4mixed{\times}3times$) specimens were manufactured. As results, the compressive strength of porous concretes were from 59 to $267kg/cm^2$ depend on mixed ratios between cements and coarse aggregates. Voids of concrete were from 33% to 40% and the pH were varied pH 8-10.5. So the capability of planting vegetations was to be ascertained. The germination and growth of grasses were not good, but it could be found out that the capability of vegetations on the concretes. For generalizing these results and applying on the construction sites, it is necessary to verificate following studies for various conditions.

This study was conducted to evaluate the effects of the LOHAS index value of school food service employees on the purchase of food materials and foodservice quality. The subjects consisted of 566 foodservice employees. The findings were as follows. (1) The foodservice employee's LOHAS index fell within that of a NOMADICS group with an average of 72.18 points out of 100 points. (2) When the age, working experience and LOHAS index of the foodservice employees was high, the necessity, view, interest and recognition of LOHAS introduction for the improvement of the foodservice environment was high. (3) The amount of environmentally-friendly food materials purchased by foodservice employees was high, when they had a high LOHAS index. (4) High foodservice quality management items of foodservice employees were 'sanitation management' (3.87 points) and 'human resource management' (3.84 points), whereas 'menu management' (3.57 points) and 'food material and inspection management' (3.61 points) scored low. (5) The LOHAS index of foodservice employees has a significant impact on the purchase intention of environmentally-friendly food materials in LOHAS and NOMADICS groups. (6) This study confirmed that a higher LOHAS index of foodservice employees was associated with higher foodservice quality management behavior, which leads to an improved quality of foodservice.

산업과 기술이 발전하면서 점점 더 향상된 기능과 성능이 우수한 접착제를 요구하고 있다. 고무수지의 장점, viscoelastic 한 점을 이용하고 단점을 보완하기 위하여 반구조 형태의 점착 접착제를 개발하였다. 또 용매를 이용하지 않아 요즈음에 문제가 되는 환경에도 부담을 줄이는 친환경성 점착제라 할 수 있다. 한편에 epoxy functional group과 다른 한편에 hydroxyl functional group을 함유하고 있는 poly(ethylene/butylene)과 한편에 hydroxyl functional group를 가지고 있는 poly(ethylene/butylene)에 UV 개시제를 이용하여 interpenetrating polymer network (IPN) 구조를 형성하고 여기에 점착 부여 수지로써 hydrocarbon resin을 첨가하여 고온에서 고무 수지가 갖고 있는 단점을 보완하였다.

21세기는 유기체적 세계관의 발달과 함께 환경친화적 접근이 조형계에서 크게 부각되고 있다. 이제 환경친화디자인은 단순히 환경보호적인 차원을 넘어 인간과 기술, 환경이 함께 호흡하는 유기체적인 환경친화, 환경과의 일치의 개념으로 발전해 가고 있다. 그러므로 본고는 현대에 발전하고 있는 환경친화디자인의 유형, 즉 자연보호적인 접근이 중심이 된 입장과 인간과 환경의 친화관계 회복이 중심이 된 입장의 두 가지 환경친화디자인 유형을 조사하고 이의 필요성과 Green Amenity에 의거한 기능을 분석하고자 한다. 그리고 이 중에서 단절된 인간과 자연환경의 유기적 연결성을 강조하는 환경친화디자인에 초점을 맞추어 이에 해당하는 공간 디자인 사례를 제시하고자 한다. 이를 통해 인간이 소원하는 삶과 환경에는 편리함과 관련된 기술적 물리환경 뿐만이 아니라 생물적 소산을 이용한 자연친화적 구상이 필요함을 논증해 보고자 한다. 공간디자인에 있어서 이런 접근은 인간과 자연의 단절된 친화관계 회복에 도움을 줄 수 있으며 이렇게 인간과 자연의 친밀감이 회복될 때에 자연보호를 위한 인간의 노력도 유기체적 방향성을 가지고 바람직한 성과를 거둘 수 있다고 본다.

This work aims the search of environmentally friendly pre-treatment technologies to develop chromate replacements for metal finishing industries due to its toxicological properties. Since the corrosion resistance of steel was strongly related to water permeation, galvanized steel sheets were treated with various hydrophobic silane compounds and water-suspended polymer solution. Also, plasma gas discharge was applied to modify the surface of a polymer coated-steel sheet to be hydrophobic. The surface hydrophobicity of materials was introduced by CF$_3$H plasma exposure. The corrosion property before and after the plasma treatment was investigated in a slat spray tester with 3.5 wt.% NaCl at 35$^{\circ}C$. The results showed that both silane/polymer double coatings and plasma treatment of the galvanized steel exhibited significant retardation of corrosion.

Regional Agricultural Cluster(RAC) at Asan area has been formed with Purundeul farming union corporation(Purundeul) as the center from the year 2005. Originally, RAC has been proceeded by Ministry for Food, Agriculture, Forestry and Fisheries (MFAFF) all over the nation from 2005. This RAC has helped Asan area to establish the foundation of environmentally friendly agriculture(EFA) searching for nutritional cycle. This also made jumping age turn developing age in EFA at Asan area. The number of Purundeul producer members was 386 farmers in 2008. Purundeul introduced organic livestock farming(Korean beef cattle; Hanwoo) for proceeding EFA searching for nutritional cycle in 2007, and had 719 cattle at the end of March 2009. Feedstuff materials for organic livestock is mostly produced from seeding farming by-products within Asan or the country. Asan RAC had built factories for feedstuff producing and beef processing with producers' investment.

The environment-friendly abrasive materials of starch series has a wide range of application value such as deburring of plastic injection products, paint exfoliation and surface treatment of painted products and polishing, etc. In this study, an experiment of paint exfoliation was performed by using the environment-friendly abrasive materials made of cheap starch, and its performance was reviewed. By adjusting the grit size of abrasive materials, nozzle pressure, nozzle feed and number of nozzle repetition, paint could be exfoliated effectively. In this experiment, it was found that the most suitable condition was grit size 0.75~1.0 mm, nozzle pressure 0.4 MPa, nozzle feed 5 mm/min and number of processing repetition 2 times.

This study attempted to analyze the characteristics of interior design of the apartment units of Model-houses in terms of ecological aspects. 9 companies that possessed their model houses among the construction companies in Busan area as of August 2006 were selected. 20 units in the model houses of these companies were visited and analyzed. Through literature review, the guideline for the environmentally-friendly residential design was designed and developed to the checklists. The data collected were analyzed to find out the ecological characteristics of the interior space of apartment units. The findings are the followings. First, energy efficiency was properly considered in terms of natural lighting and natural ventilation. Second, in sustainability, the materials for floors and walls could not be reused even though they were environmentally-friendly. Water system needs more improvement for sustainable development including grey-water and rain recycling system. Third, interior greening should be applied more for better environment both physically and emotionally. It is expected that future housing will be more high-risen and densely-populated apartment spaces. Therefore, an approach to new ecological aspects including an emphasis on interior greening, use of eco-materials and adhesives, water recycling and flexibility of the spatial configuration should be made for the next generation.

Concern about global environment has been increasing in recent years. Efforts to minimize the environmental impact to the globe as well as human beings have increased, especially in the late twentieth century. The study researches one of the solutions for the environmentally friendly building construction, which can contribute to sustaining the world environment. Assessment and proposals are made for high-rise apartments, one of the most popular construction types nowadays in Korea. Careful building design and construction for apartment buildings could reduce the environmental impact significantly without lowering standards of living. Since the volume of high-rise apartment construction is so great, a small improvement in each building will make a great contribution. Assessments are made over the life-span of apartment buildings. A tool has been made through references from western examples. mainly from BHEEAMs made in the United Kingdom. The components of the tool include passive design strategies, building materials. energy consumption during building operation, and management and maintenance. Co-relationship between buildings and ten environment in Korea is searched. Korean high-rise apartments are assessed with the tool and suggestions for sustainable development are made mainly for improvement of embodied energy of building materials and the life of buildings.
