In this study debris like branch or trash are washed and flowed from land to stream by rainfall runoff at mountain or urban stream specially rainy season. These kinds of debris are accumulated at hydraulic construct on the way of flow along the stream. The shape or ratio of like these accumulated debris are various according to the location where it is accumulated and the material what it is, so that it is influenced to be varied to flow characteristics. To be simple of accumulated debris shape, it was made experiments though the variation of open ratio and the shape of accumulated debris by lab experiment using straight channel with two piers. From the result, the water level is inverse proportion to open ratio, and the water level more sensitive to the debris‘ width than length at the same area of accumulated debris.

The concept of Eco-city is to protect the city against development, trash, and industrialization. But the sprawl phenomenon of urbanization and industrialization are accompanied by the environment destruction. Therefore the importance and definition of eco-city were suggested. And to restore the urban ecological network, the prototype direction of eco-city at YongJeonDong in DaejeonCity were suggested in this study. It is believed that how to create an eco-city is an artificially developed $\square\square$Yong-Jun Dong$\square\square$ is a pending issue we are faced with situation. Herein lies the necessity of natural environment restoration and creation based on the so-called the Third Ecology

최근 연구조사에 의하면 전세계에서 배출되는 하루 평균 쓰레기는 450만톤으로 그 양이 해마다 증가하고 있는 실정이다. 쓰레기는 환경오염, 전염병 발생 국가적인 경제적 손실 등과 같은 심각한 문제를 발생시키는 주요원인이기도 하다. 이러한 상황에 대해 최근 다양한 방법으로 쓰레기를 줄이기 위한 연구 등의 노력이 이루어지고 있는 실정이다[1]. 본 연구팀은 저비용 고효율의 효율적 시스템을 구성할 수 있는 IoT 센서와 아두이노를 활용하여 쓰레기를 줄일수록 유도할 수 있는 스마트 쓰레기통을 개발하고자 하였다. 쓰레기가 생산되는 것을 실시간 데이터화하고 이를 활용해 사용자 실시간 알림과 같은 서비스를 구성할 수 있었다.

The purpose of this study was to investigate middle school students' perceptions about global environmental problems using drawings. The study was involved the collection of drawing data from 112 ninth grade students from a middle school in Daegu Metropolitan City. The environment task was administrated to students drew a drawing of an global environmental problems and explained their drawing in their own words. Also, students was asked to write what he or she can do to solve global environmental problems. The results are as follows: First, air pollution is the most important global environmental problem, followed by water pollution, global warming, sea level rise, deforestation, waste, loss of biodiversity, and so on. Second, the students' drawings were characterized into two aspects: One is a macroscopic viewpoint and the other is everyday viewpoint. Third, the students' practical action plan to do solve global environmental problems were walk, public traffic, do not throw trash, plant trees, etc. Educators should take into account the perceptions of global environmental problems and teaching-learning strategies to enhance students' understanding of global environment.

This research is about Apartment Remodeling Upgrading Programme by Singapore Housing Development Board(HDB). For this study, we visited HDB and made field survey of the projects. There are basically three types of upgrading, namely, Precinct Upgrading, Apartment Block Upgrading and Flat Upgrading. Precint Upgrading refers the upgrading of services and facilities of the precinct. It involves the extention of open space, car-park, commercial space and additional covered linkways. These afford the residents greater convenience and comfort and generally enhance the environment of the community. Apartment Upgrading refers the upgrading of the block facade, improvements to the elevator, lift lobbies, letter boxes, trash chute and rain chute. The upgrading improves the quality of life of the residents. Flat Upgrading Involves the addition of space which may be in the form of a new Utility-room, replacement of old services, piping and equipment within an apartment unit. These provide the residents with a bigger and more comfortable living space.

In these days, the pollution of marine environment near island at Korean coastal zone caused by the trash human waste and livestocks excreata become intensified. One of the most economic and efficient way to prevent this pollution problem is to set up island circulating incineration system. In this paper, the result of feasibility study on the application of turtle boat hull form to the incinerating vessel has been summarized especially for the resistance and course keeping point of view.

Even though the Korean intoner architecture market has constantly developed in the past on the basis of the economic and social growth, it has had a tough time for varied reasons since 1998. Restructuring in the construction industry is required due largely to both the lack of market demand which resulted from the foreign exchange crisis and managerial trouble which is getting worse as time goes by. In actual, as the social necessity for remodeling in skyrocketing, the remodeling is getting more acclaim. That is because old architecture generates a great amount of architectural trash, and it is necessary to look for ways to saute the energy. In the wake of these situations, the remodeling industry is drawing attention as an alternative to the marketable limitations of the existing construction industry. However, it is true that the remodeling market has yet to be activated decisively. Accordingly, the purpose of this paper is to provide a basis for entering into and activating the remodeling market of the interior architecture industry by analyzing the scale and recent conditions of the remodeling sector.

산업화 이후 무분별한 자원 개발로 인해 쓰레기 배출량은 증가하였으나 그 양을 감당할 쓰레기통의 개수는 부족하다. 그리고 쓰레기통이 있음에도 불구하고 시민의식 부족으로 인해 일반 쓰레기와 재활용쓰레기가 같이 버려져 있는 상태를 흔히 볼 수 있다. 작은 예로 자취하고 있는 대학생들 자취방 앞이나 상가 건물 앞에 분류되지 않고 아무렇게나 버려져있는 쓰레기들을 많이 볼 수 있다. 이는 환경 미화원이 직접 재분류를 하고 청소하는데 시간과 인력 비용이 낭비하게 된다. 본 논문은 이러한 문제점들을 개선하고 보완하고자 쓰레기를 자동으로 분리수거할 수 있는 '자동 분리수거가 가능한 쓰레기통'기술을 제안한다. 이는 분리수거율을 증가시키고 분리수거 다시 할 불필요한 시간과 인력과 예산을 줄일 수 있고 재활용된 자원을 사용하여 생산 자원을 줄여 원가 절감효과와 에너지 소비를 줄일 수 있다. 이로 인해 자원을 생산할 때 발생하는 탄소와 온실가스 방출량을 감소시켜 지구 온난화를 예방할 수 있다.
