Studies on landscape ecology have focused on conceptual aspects, while empirical focus for spatial planning has been rarely conducted. This study conducted an empirical analysis to enhance landscape ecological performance of urban developments using landscape ecology. To do so, concrete criteria and standards to analyze structural, functional and variational mechanisms of urban landscape ecology were developed. An integrated landscape ecology assessment model that can be applied to urban development planning was established by combining the criteria. Next, Landscape Ecological Management System (LEMS) was developed to implement an integrated assessment using GIS. To verify the effectiveness of the system, a case study was conducted using LEMS on Byulnae City in the Seoul Metropolitan Area. The LEMS can be useful for urban planners and policy makers in their selection of desirable planning alternatives. Moreover, the LEMS developed in this study can be a useful tool for academia in terms of the implementation of further related studies, and for planning professionals in their environmental impact assessment tasks.

Concerns over the environment have spawned a number of research studies in the construction industry, as the construction of built environments and large infrastructures involves diverse environmental impacts and loads of hazardous emissions. Many researchers have attempted to quantify these environmental loads, including greenhouse gases, carbon dioxide, nitrogen dioxide, and sulfur dioxide, to name a few. However, little research has been conducted regarding integrating the life-cycle assessment (LCA) of environmental loads with the current life-cycle cost analysis (LCCA) approach. This study aims to estimate the environmental loads as a monetary value using the European Climate Exchange (ECX) rate and, then, to integrate those impacts with the pure construction cost. Toward this end, this study suggests an integrated approach that takes into account the environmental effect on the evaluation of the life-cycle cost (LCC). The bill of quantity (BOQ) data of a real highway project are collected and analyzed for this purpose. As a result, considering the environmental loads in the pavement process, the total LCC increased 16% from the traditional LCC cost. This study suggests an integrated approach that will account the environmental effect on the LCC. Additionally, this study is expected to contribute to better decision-making, from the perspective of more sustainable development, for government as well as for contractors.

Web based integrated sewer management system was developed for the analysis of sewer flow and for the optimal operation of sewer works using ArcView and SWMM. SWMM and ArcView were dynamically linked together using Avenue in order to construct user-friendly information management system. The developed system was applied to the residential area in Choonchun city to verify its utilities. All the relevant field data were analyzed on the basis of the developed system, and the modeling of sewer flow was implemented using RUNOFF, EXTRAN, TRANSPORT in SWMM. This system is now in the process of connection to the management system of stormwater, surface and subsurface environment in order to develop an integrated environmental management system. Futhermore, this system will be a critical part of overall control system of sewer works including sewer network and wastewater treatment plant. As this system can provide comprehensive prediction of flow and pollution profiles, it could serve as a tool not only for the optimal management, but also for the decision support system to examine the efficiency of planning and implementation of sewer projects.

본 연구는 연안 육역 및 해역에서 일어나고 있는 해양 신재생에너지 개발계획 및 추진사업을 분석하고, 해양환경 및 생태계와 관련된 중점평가사항을 진단하여 효율적인 스코핑(Scoping) 방안과 정책제언을 제시하였다. 주요한 사업유형으로는 공유수면에는 조력, 해상풍력 및 파력발전이 많았으며, 연안 육역에는 태양광발전사업이 주로 계획되었다. 조력발전 등 대규모 개발사업 추진 시, 상위계획에 따른 전략환경영향평가(SEA)와 공유수면매립기본계획 등 사전평가단계에서는 입지의 타당성과 계획의 적정성 측면에서 연안관리지역계획에 따른 용도구역 등 다른 계획과의 조화, 실질적인 대안분석, 그리고 해양수산 규제지역 분포와 어장이용 등 기 해양공간계획과의 상호 연관성 진단 등이 중요하다. 또한, 해역이용협의나 환경영향평가 등 실시단계에서의 구체적인 평가에서는 사업유형별로 중점평가사항에 대한 철저한 진단, 실효적인 사후모니터링 및 저감방안의 제시가 핵심으로 고려되어야 할 것이다. 특히, 순수하게 해양공간에서 일어나는 에너지발전사업일 경우에는 해양공간계획 방향과 연계되는 사전평가방안 도입 및 통합 "해양환경영향평가" 체제로의 전환 등 해양수산부가 주도하는 평가제도의 개선방안이 필요할 것으로 판단된다.

The application of Photovoltaic (PV) power in the building sector, is expanding as part of the ongoing energy transition into renewables. The article addresses the question of sustainability of energy generated from PVs through an environmental assessment of a building-integrated PV system (BIPV) connected to the grid through net metering. Employing retrospective life cycle analysis (LCA), with the CCaLC2 software and ecoinvent data, the article shows that the carrying structure and other balance of system (BOS) components are responsible for a three times higher energy payback time than the literature average. However, total environmental impact can be lowered through reuse or reinstallation of PVs on the same building structure after the 30-year interval. Further ways to improve environmental efficiency include identifying the most polluting materials for each LCA parameter. The results of this study are of interest to researchers and producers of PVs and organizations investing and promoting decentralized power production through PVs.

Integrated management of Korea national and environmental planing for sustainable development is suggested, and basic research is needed. In this study, national and regional plans were assessed using 'integrated management index of Korea national planning and environmental planning' to grasp the current status of integrated management on Korea national planning and environmental planning. As a result of the assessment, it was found that both national and regional plans need to improve considering the natural ecology part and water resource and quality part. In addition, it was derived that the detailed contents of the indicator can not be reflected according to the characteristics in the higher-level plan. Therefore, it has been found necessary to include proclamatory contents so as to be able to establish a detailed plan that reflects environmental goals in the lower-level plan.

Environmental Impact Assessment (EIA) serves to identify a project's possible effects on the environment early enough sufficiently allowing for them to be taken into account in the decision-making process. The EIA in Germany is an instrument of environmental Policy which considers nature as an integrated system (ecosystem). In the german process of developing environmental policy, the EIA has been one of the instruments which introduced by law rather late. This means that the German Law of EIA has been made in 1900, 20 years after the beginning of the environmental policy in Germany. In the following paper I intend to ${\cdot}$ explain the basic concept of the EIA in Germany ${\cdot}$ describe the process of law building for EIA ${\cdot}$ give a short overview of applications and experiences with EIA ${\cdot}$ show the links between EIA and general environmental policy in Germany.

Due to fossil fuel depletion and environmental pollution, H2 production from organic waste has received an increased attention. In this study, we present an integrated process for the H2 production from biogas and evaluate the economic feasibility and sustainability via rigorous techno-economic analysis (TEA) and life-cycle assessment (LCA). Through the TEA, we determine the minimum H2 selling price using discounted cash flow analysis and investigate the main cost drivers. The environmental impact of the proposed process is quantified via LCA.

The study is intended to develop the measures to introduce the Environmental Impact Assessment (EIA) project manager (Environmental Assessor), who will be responsible for leading the EIA task. This role requires a quality standard of expertise in the area of natural science, social science, knowledge and technology on environment design mechanism, and the integrated approaches that combine the relevant policies and systems. To facilitate the system, the certificate will be given to the person who is well acquainted with the knowledge on EIA with relevant experiences, thereby authorizing them to coordinate the assessment task for reliable outcome. Hence, the need for introducing the system is very crucial. The EIA project manager, as a guide for an EIA project team, shall be the person who has a comprehensive understanding of the project, the knowledge about the principal for implementation of EIA and the expertise in structuring the management system, with a skill to maintain the good relationship with the people engaged in the project. To that end, it is highly recommended to set up such a certificate system to be incorporated in the college curriculum.
