Through the courses of industrialization, speedy growth and pluralism. The problems about the environment- friendly structures have become very important problem. Especially, it is getting highly appear to the expectation about the environment friendly buildings in Kangwon-do where has greacefully clean environment. The guide line for Kangwon-do can be arranged to the following through the varity analysis, outside enviroment, color, construction materials, outside design etc the guide line for Kangwon-do can be arranged as to the followings. It appears to be suitable to country houses in kangwon-do that is made of timber or red-bricks with green half circled roof and give a sense of warmth and soft. but the coastal area village is appeared wave style roof with orange color and surrounded by natural building stones or a line- plastered wall making complicated.

In this study, an environment-friendly synthetic strategy to process zinc oxide nanocrystals is reported. The biosynthesis method used in this study is simple and cost-effective, with reduced solvent waste via the use of fruit peel extract as a natural ligation agent. The formation of ZnO nanocrystals using a rambutan peel extract was observed in this study. Rambutan peels has the ability to ligate zinc ions as a natural ligation agent, resulting in ZnO nanochain formation due to the presence of an extended polyphenolic system over the whole incubation period. Via transmission electron microscopy, successful formation of zinc oxide nanochains was confirmed. TEM observation revealed that the bioinspired ZnO nanocrystals were spherical and/or hexagonal particles with sizes between 50 and 100 nm.

After inquiring into physical characteristics of using fly ash and alkali solution, it was found that higher pH density is favorable to strength development at early age and the higher the age is, the higher the compressive strength gets. Also, it was found that when there is more addition of activator, the compressive strength is higher. I was shown that more than atmospheric curing, steam curing was favorable for development of compressive strength. When the temperature of curing temperature was higher, most of the compressive strengths were higher. Thus, based on this study, it was understood that environmental-friendly chemically combined concrete using fly ash and alkali solution can be utilized without using cement.

This study reports an environment-friendly synthetic strategy to process nickel oxide nanocrystals. A mesoporous nickel oxide nanostructure was synthesized using an environmentally benign biomimetic method. We used a natural rambutan peel waste resource as a raw material to ligate nickel ions to form nickel-ellagate complexes. The direct decomposition of the obtained complexes at $700^{\circ}C$, $900^{\circ}C$ and $1100^{\circ}C$ in a static air atmosphere resulted in mesoporous nickel oxide nanostructures. The formation of columnar mesoporous NiO with a concentric stacked doughnuts architecture was purely dependent on the suitable direct decomposition temperature at $1100^{\circ}C$ when the synthesis was carried out. The prepared NiO nanocrystals were coated on cotton fabric and their antibacterial activity was also analyzed. The NiO nanoparticle-treated cotton fabric exhibited good antibacterial and wash durability performance.

The global warming because of the CO₂ emission and solution about this emerge as the international enviroment problem. Particularly, it is the absolutely it is needed for reducing the CO₂ in the cement industry and harmful material actual condition. And the construction of home and abroad and material manufacturers tries for the technology development for the carbon dioxide and harmful material reduction which the portland cement in manufacture is usually emitted along with the increase of concerns about the environment-friendly concrete and panel. Therefore, in this research, the compressive strength of the inorganic binder and flexural strength tries to be measured in order to draw the inappropriate high temperature cure time of the ternary system inorganic binder using the blast furnace slag, red mud, silica fumewhich is the industrial byproduct with the cement substitute material, and etc.

Chonan and Asan city have been a focal point due to rapid development as the first station for Express Railroad and key cities West Coast Development Region. Gokgyo stream adjacent to the cities plays an important role as a drainage channel for an agriculture and a discharger of urban storm water. Waster quality of the stream has been deteriorating caused by pollution sources such as a untreated wastewater discharge and runoff from the watershed. In the study, we conducted 4 surveys in April, May, July, and September to understand the current state of water quality for the stream and to make it possibe to predict future water-quality variation for future development. The system runs on a personal computer under the windows enviroment and provides extensive graphic user interface(GUI) for user-friendly assessment. Using the pull-down menus provided by the GUI panel, the user is able to operate the system by pointing and clicking the icon to identify the state of water-quality at locations concerned. Furthermore, we developed an integrated watershed management system. The constructed system could be a useful tool as a decesion maker for pollution source control strategy.

한국의 농업분야에는 여러 가지 인증제도가 존재한다. 그 예로 유기농산물 인증, GAP인증, KPGI인증, TOP푸르트/TOP라이스 인증 등이 있다. 이러한 인증제도는 소비자에게 안전하고 고품질의 농산물을 보장하기 위해 시행되었다. 하지만 각 인증제도가 명확한 목적을 보유함에도 불구하고 이러한 인증제도들이 소비자에게 관련정보를 수반하는데 성공적이지 못하다는 평가를 받고 있다. 그 이유로는 현존하는 몇몇의 인증제도가 오히려 소비자들을 혼란스럽게 하고 있다는 것이다. 그리고 각각의 인증제도를 별도로 유지하고 홍보하는 것은 더 많은 비용을 발생시킨다. 이 연구에서는 여러 인증제도를 활용하여 이러한 문제를 해결하고자 하는데 그 목적을 두고 있다.

본 연구의 목적은 대학교 재학생을 대상으로 포토보이스 질적 연구방법을 활용하여 대학생이 인지하는 환경, 환경장벽, 친환경 행동의 모습을 파악하고자 하였다. 포토보이스 방법론을 활용하여 대학생의 시각으로 바라본 친환경행동의 동인과 행동의 모습을 공유하고 그에 관한 의미를 고찰하는 과정을 통해 친환경행동의 실천적 방안을 제시하고자 하였다. 환경이라는 대 주제 하에 참여자들이 직접 선정하여 다루게 된 3가지 하위 주제는 '내가 생각하는 환경이란', '나에게 환경장벽이란', 그리고 '나의 친환경 행동이란' 등으로 주제별 참여자가 일상생활 중 직접 촬영하여 선별한 사진을 통하여 자신의 생각을 표현하고 타인의 의견을 청취하여 공유하였다. 이러한 연구의 결과는 첫째, 연구 참여자들은 환경에 대하여 '낭비', '불편함', '미세먼지=환경오염', '위선태도' 등으로 직접 촬영하여 선정한 사진의 의미를 부여하였다. 둘째, 연구 참여자들은 환경장벽에 대하여 '비가시성', '무관심', '사회적시선', '비효율성', '강제성' 등으로 선택된 사진의 의미를 부여하였다. 마지막으로, 연구 참여자들은 친환경행동에 대하여 '리사이클', '에너지절약', '재사용' '일회용품 사용 줄이기' 등으로 선택된 사진을 의미화 하였다. 이러한 연구결과를 바탕으로 V-A-B모델의 확인과 소비자는 개인이 가진 가치와 태도, 그리고 행동이 위계관계를 구성한다는 점을 확인하였으며, 소비자의 일상생활에서 친환경 행동을 실천하는데 방해 요인이 분명 존재하고 있으며, 친환경적 소비 행동을 실천하기 위한 불편함 혹은 비편리성을 해소할 수 있는 방안이 필요하다는 연구의 시사점를 제시하였다.
