산업이 해를 거듭할수록 발전하면서 매연, 분진, 폐기물과 같은 물질의 발생과 동반하는 황사, 스모그 같은 환경적인 오염 문제가 현재 큰 문제로 대두되고 있는데 이는 인간의 신체에 해로운 영향을 준다. 우리는 이런 오염에 대해 특정 기관의 정보를 통해서 환경 오염에 관한 수치를 정보로써 취학 이 정보를 바탕으로 신체에 대한 오염을 대비하는 방식으로 생존하고 있는데 사물인터넷 중에서도 인간과의 접근성이 가장 뛰어난 거울을 이용하여 환경적인 정보 알림을 통해 IoT 스마트 미러 시스템의 새로운 환경적 가치 창출 과정을 설명한다.

The development of the industry has increased the indoor living time of modern people. Therefore, indoor pollution is attracting attention as a social issue. One of the indoor air pollution is formaldehyde. Formaldehyde has been classified as a first-level carcinogen by international cancer research organizations. Formaldehyde has been used to protect products such as construction materials and finish materials, and being diffused in the interior construction process. In this study, we used phytoncide with cement matrix to reduce formaldehyde, an indoor environmental contaminant. The strengths was increased slightly and formaldehyde showed a reduction effect over time.

World trade has been increasing continuously in total volume, on the other hand, environmental protection on sea and conservation of fishery resources has been rising up the major issue. All of the world are pushing their efforts two major purposes to the full, one is taking competitive place in marine transportation throughout the world and another Is environment protection. Pusan Port as world leading Port put its all effort in bring more ocean going vessels and securing their traffic route by providing them more information related marine traffics through PTMS in port. During two years of operation, statistics of marine traffic accidents showed that many dynamic casualties such as collisions, groundings, and rammings has been decreased. However, due to increasing cargo volume, limited water area and unpredictable weather condition, potential risks still exist high. In this paper, in order to maximize the efficiency of PTMS and reduce various risks in the future, we examine risk factors over operational results and experience, and propose reasonable operational methods of PTMS.

Recently, Grid is embossed as a new issue according to the need of cooperation related to distributed resources, data sharing, Interaction and so on. It focuses on sharing of large scale resources, high-performance, applications of new paradigms, which improved more than established distributed computing. Because of the environmental specificity distributed geographically and dynamic, the most important problem in grid environment is to share and to allocate distributed grid resources. This paper proposes supply-driven strategies model that is applicable for resource management in grid environment and presents a optimal resource allocation algorithm based on resource demands. Supply-driven strategies model can offer efficient resource management by transaction allocation based on user demand and provider strategy. This paper implements the supply-driven strategies model on the DEVS modeling and simulation environment and shows the efficiency and excellency of this model by comparing with established models.

It is necessary that End-of-life Vehicle (ELV) should be recycled from the point of view of environmental preservation and resource recycling. This paper deals with two issues. The first one is the basic functional construction and plant layout of the ELV dismantling system that can maximize the reusability of parts and the recyclability of materials. The second issue is the development of a simulation model which can be used to estimate the performance of the layout design. The simulator has been interfaced with an interactive layout design system, and used to effectively determine an optimal layout design of the ELV dismantling system.

Greenhouse gas emissions and excessive energy consumption have been an on-going world issue nowadays. We can find that the majority portion is caused by high-rise office buildings. In order to resolve these problems, it is extremely important to implement various active or passive strategies in a building design. To successfully meet these design goals and energy reduction approaches, a project building must utilize an efficient design process from the early start. One of the most effective project delivery process called Integrated Project Delivery (IPD) will be implemented in a case study project building (KEPCO) during design phase and show how important it is to plan a project's green environmental performance goal together through an early collaboration from all key project participants, which helps to construct an successful green building design without any critical construction pitfalls.

High speed and large transfer capability of railroad has been an important issue in Korean since KTX opening at 2004. Improvement projects for railway electrification are progressed in the conventional line as well as high speed line because various operation plan is performed such as interaction between high speed line and conventional line and operation of tilting train etc. Especially, railway electrification has many advantages which are cost effective and eco-friendly. But it also has some problems such as construction costs and accidents due to electrification. Therefore this paper developed measuring index of electrification railway benefit. By comparing between diesel and electrical locomotive, the operations of before and after the electrification and measurements quantitative index such as energy efficiency, enlargement of transfer capability, environmental pollution and maintenance and efficiency of operation is presented. In the future, Overall benefit and cost of railway electrification will be analyzed.

The issue of sustainability has been prevailed not only in building industry but also all other industries. It has been raised that the concept of sustainability should take into account for the design of multi-use high-rise apartments. In this study, the present situation and trends of the multi-use high-rise apartment construction have been reviewed. The definition of sustainable design of high-rise apartment has been clarified so as to perceive the related design elements through the literature survey. Finally this study has derived the sustainable design elements of high-rise apartment unit plans through the comparative analysis of sustainable design guidelines, environmentally friendly building accreditation systems and literature survey in and abroad.

Each year the amount of construction wastes increases at a rapid pace. Particularly, wastes from apartment housing projects that make up 89.14% of the total construction projects have increased about 48% as compared with those of the year 2000. Construction wastes are therefore rising as an issue related to environmental problems and disposal costs. And there are ongoing studies of the disposal, control and recycling of construction wastes. Mitigation measures for the wastes, however, have been a rare subject of research that focuses on waste-generating factors by activity during apartment housing projects. Given that, the purpose of this study was to categorize construction wastes by work type and to identify the factors causing wastes in order to reduce them. This study investigated the amount of the wastes from apartment housing constructions by activity as related to disposal costs, and examined causes in the ordering, transport, material management and construction stage, respectively. The analysis results will likely bring about expectation effects that help reduce the generation of the wastes by establishing action plans.

Although for its great amount and cleanness solar energy has been studied a lot as a substitute one, it is limitedly being utilized in heating water and partly in special usage for high cost of installing solar cell in Korea. Consider domestic shortage of natural energy resources and environmental issue by the Climate Agreement treated in 1994, it is urgently needed to study the practical application of solar energy as a substitute one. Therefore in order to increase the efficiency of solar cell and decrease its price, this study treats the course of designing and manufacturing the panel that connects sunlight by fixing reflector.
