In order to alleviate the environmental pressure caused by production process of thermal power plants, the application of cleaner production is imperative. To estimate the implementation effects of cleaner production in thermal plants and optimize the strategy duly, it is of great significance to take a comprehensive evaluation for sustainable development. In this paper, a hybrid model that integrated the analytic hierarchy process (AHP) with least squares support vector machine (LSSVM) algorithm optimized by grid search (GS) algorithm is proposed. Based on the establishment of the evaluation index system, AHP is employed to pre-process the data and GS is introduced to optimize the parameters in LSSVM, which can avoid the randomness and inaccuracy of parameters' setting. The results demonstrate that the combined model is able to be employed in the comprehensive evaluation of the cleaner production in the thermal power plants.

The goal of this study was to establish the evaluation method, which consist of the principle, factor, procedure and checklist, on environmental camp program and then to support staffs of environmental camp for decision-making to improve pre-program and develop new one. The main principles of the evaluation method established in this study were Hierarchical holism and Open inter-communication. First, hierarchical holism focused at the interaction among six factors, which were divided by 3 steps : 1) goal(and objectives) 2) learners and sites 3) activities, staffs and media. Second, open inter-communication could be defined a feedback process among all program participants : manager, staff, teacher, volunteer, learner and so on. The evaluation checklist had been developed of 10 comprehensive items and 30 factor-items at the preliminary step but some items were assessed some complex or duplicate in the result of 3 case studies. The suggested checklist was diminished to 5 comprehensive items and 25 factor-items. Several alternatives, which included specifing learners and objectives, developing site-oriented program and establishing the evaluation sheet were suggested for improving environmental camp program.

The goal of this study is to examine municipality comprehensive plans by recognizing the problem that adverse impacts of urban regeneration impede the sustainability of specific renewal project. 10 major cities in Korea that are experiencing urban decline were chosen for the study area and plan evaluation indexes were adopted based on the sustainable urban regeneration principles in terms of environmental, social, and economic aspects. Plan evaluation was conducted by employing the content analysis method and developed assessment indexes for three sectors (factual basis, goal/objective, and policy/action) of plan. The findings show that policies, such as 'expansion of parks in urban area,' 'pedestrian-oriented street improvement project,' and 'countermeasures for local industry revitalization,' should be fundamentally included in adopting sustainable urban regeneration plans. Plan scores regarding sustainable urban regeneration had an insignificant relationship with the status of administrative district and plan adopted year. This is because metropolitan municipalities, including Ulsan, Daejeon, and Daegu, received relatively low plan score compared to local governments like Goyang and Suwon. Also, Daegu and Suwon, which established their comprehensive plan in 2018 obtained lower score than Seoul and Incheon, where its plans were created before 2015. Evaluation protocol and indexes that were suggested in this study can be used while reorganizing each locality's comprehensive plan, and thus, play as one of major bases in preparing future sustainable urban regeneration projects.

Environmental Impact Assessment (EIA) is an important policy implemented before starting development projects to estimate and reduce environmental impact. However, the difficulty of quantification on several rating categories has hampered comprehensive analysis. Instead of it, the current EIA just summarizes outcome of investigation. Therefore, EIA fails to definitively ascertain whether the development shold be approved or not. This study aimed at providing the way to comprehensive decision-making by applying Emergy analysis and Emergy indicators to EIA. Production (P), Emergy Yield Ratio (EYR), Environmental Loading Ratio (ELR) and Emergy Sustainability Index (ESI) were selected for indicators. The indicators of range approving the development were set up with comparing before and after development or according to circumstances of which view of average that was classified as region or industry is appropriate to analysis. As a result, the value after development of P should be higher than the value before development. EYR and ESI of the value before development should be higher than region or industry average. On the contrary to these, ELR of the value after development should be lower than region or industry average. To verify applying Emergy indicators to EIA comprehensive analysis, Emergy evaluation was conducted to real case. As a result, applying Emergy analysis could suggest whether the development is appropriate or not. These indices and the result of this research are expected to be applied decision-making on environmental impact for sustainable development.

The natural environment of the modern society does not simply reflect damage, but is a complex and grave reality that threatens the Earth. To solve this problem, various aspects related to the natural environment have been explored around the world, and a number of studies are ongoing to balance the development and preservation of the natural environment in Korea. However, no clear category exists for the natural environment and the related terms are ambiguous, rendering the overall evaluation system is in efficient. Therefore, the present study attempted to set the scope of application of a comprehensive evaluation system based on terms similar to the natural environment, concepts of the natural environment viewed from a value-based perspective and a capacitive perspective. In addition, by examining the concept of ecosystem services, a conceptual model for efficient application of the evaluation system of the natural environment through the association between categories of the natural environment is presented to derive implications for practical operation in the future.

The need and importance of developing and utilizing the oceans, not only as sources of renewable energy and mineral resources, but also as countermeasures to global warming such as for CCS (carbon capture and storage), have continued to increase, especially in countries with limited land areas and resources. Therefore, it is necessary to assess the sustainability of an ocean utilization technology or system not only from an economic point of view but also from an ecological one. For this purpose, it might be effective to develop a comprehensive evaluation method and/or index, by which the assessment of and decisions about a technology and system can be made more objectively. It would also be useful to have an environmental simulation model, which was developed and reported in a previous research. The aim of this study was to modify a reasonable and quantitative index, with which a comprehensive evaluation system can be established, to assess environmental sustainability and risk.

The main purpose of this study was to comprehensively evaluate the local agenda 21 of Daegu City based on the evaluation model and propose important measures to solve its problems and improve the limitations. As a whole, the evaluation result of the local agenda 21 of Daegu City showed very low score, only 151 points out of 500 points and revealed it was below the level in all three domains of making process, designed content, and evaluation of implementation. The making process got only score below the half in all large indicators of under-standing, driving, and rationality. This unsystematic and irrational process inevitably resulted in ambiguous and proclamatory content mainly expressing willingness to do. This fact means that the local agenda 21 of Daegu City has not served as the comprehensive local environmental plan containing visions, policies, ends and means. It did not suggest evaluation system and institutionalization of evaluation. These results of evaluation suggested that the existing local agenda 21 of Daegu City was neither useful nor effective and thus the totally new local agenda 21 should be prepared. Finally, important measures in making process, designed content and evaluation of implementation were proposed for the remaking.

Accurate and timely information on status and trends in the environment is necessary to shape sound water quality management policy and to implement water quality improvement programs efficiently. One of the most effective ways to communicate information on water quality trends to policy-makers, scientists, and the general public is with comprehensive water quality indices. The derivation and structure of a water quality index (WQI) for the classification of surface water quality is discussed. The WQI generally developed through the selection, transformation and weighting of determinants with rating curves based on legal standards and quality directives or guidelines. The representative pollutants should be included in the index, and the relationship between the quantity of these pollutants in the water and the resulting quality of the water should be based on scientific results. The WQI be simply and meaningfully formulated that nonscientifically trained users can easily become familiar with the framework of the system and use the output data to evaluate their own pollution problems.

The Protocol on Environmental Protection to the Antarctic Treaty was ratified in 1991. With the aim to ensure comprehensive protection of the Antarctic environment, it contains provisions on environmental protection and conservation of the Antarctic area, including provisions for Environmental Impact Assessment. Environmental Impact Assessment is a method used to predict environmental impacts at an early stage in project planning and design, and find ways to mitigate or prevent adverse impacts in order to maintain balance between development activities and environmental conservation. Internationally, the Environmental Impact Assessment (EIA) in the Antarctic is classified into three types - preliminary, Initial, and Comprehensive - based on the environmental impacts of the proposed activities. In case of the Preliminary Environmental Review (PER), proposed activity may proceed in accordance to the national procedures and drafting of an outline. However, Initial (IEE) and Comprehensive Environmental Evaluation (CEE) assess and verify the impacts of the proposed activity, and require methods or alternatives for mitigating or eliminating negative impacts on the environment. Although Korea's Act of 'Activities and Environmental Protection in Antarctica' also includes provisions on EIA for activities in Antarctica, there are obvious contrasts with the EIAs currently being conducted in Korea, in regards to deciding the level of EIA through screening and identifying key issues for assessment through scoping. In order to implement the proper EIA, more improved methods for drafting and reviewing the EIA to Antarctica in Korea are necessary.
