This study investigated the status and problems of marine-related environmental impact assessment and a utilization-consultation system in Korea and suggested improvement of the review organization. Also, it conducted SWOT analysis based on evaluation of functions, roles and performance of the marine environmental impact assessment center and proposed development strategies of the center through introduction of expert opinions and advanced systems. The performance statement-review by the center in 2007 included 358 cases in total; 165 (46.1%) for consultation on utilization of sea area, 104 for environmental impact assessment (29.0%), and 89 (24.9%) for prior environmental review. The consultation on utilization of sea area can be divided into that for public water surface-use (41%) and reclamation (32%), and sea aggregate extraction process (21%). Although bad impacts on marine environment are reducing under the current system, there are some limits and problems to supplement it in terms of content, system and operation. Review system on sea area utilization-impact(marine environmental impact assessment center) by marine environmental management law needs to obtain expertise, fairness and efficiency and, to do so, have operational supports and institutional improvement to maximize its own functions and roles. At the same time, it is necessary for the center to establish identity and the status as a professional review organization by setting active development strategies inside the center. Finally, it should strengthen an consultation system of marine environmental impact assessment led by the related ministry to achieve effective coastal management.

The environmental impact assessment(EIA) project in Korea has undergone changes and revisions in various evaluation items for about 30 years after the introduction of the Environmental Conservation Act (1997). However, despite the importance of land use evaluation items under the current EIA Act, there are insufficient studies to consider. Therefore, this study focused on the land-use evaluation items based on the EIA guidelines, reviewed 90 of the evaluation documents and consultation documents, and tried to suggest implications and supplementary points forthe domestic EIA land-use evaluation items. As a result, the paradigm was changing from land efficiency centered on development in the past to land efficiency centered on the natural environment and resource conservation. However, in spite of the manual for fitting the paradigm change, opinions on the conservation of the natural environment are still being drawn in the consultation document, so it needs improvement. Two improvements in the impact assessment process suggested in this study are the establishment of standardized spatial data and a quantitative impact and reduction method evaluation tool based on it. In particular, there is a need for a plan evaluation tool for land use arrangement and distribution that can solve the needs of minimizing damage to the natural environment and securing green space and a green network.

The harbor construction projects can lead to various marine environmental problems including habitat degradation and loss, marine water pollution, change of flow patterns, erosion, scour, sedimentation, and so on. The EIA is a measure to prevent various environmental problems in advance from examining and minimizing the environmental impacts before the proposed developments are implemented. In addition, institutions reviewing EIA reports have made efforts to conduct scientific and standardized EIA by applying EIA guidelines for each project. This study aims to create a EIA guideline focusing on the harbor construction projects. Based on the review comments of the harbor construction EIA reports for the past 13 years (2009-2021) and the EIA guidelines of different types of projects, we identified the marine environmental problems and provided the appropriate guideline. This guideline summarizes and presents the contents which must be reviewed in the baseline condition survey, impact assessment, mitigation, and post-environmental impact investigation in the fields of marine fauna and flora, marine physics, and marine water and sediment quality. In the case of a baseline condition survey of marine fauna and flora, a method for selecting survey points considering the characteristics of sea area and project was presented. When estimating the impact of marine fauna and flora, we presented methods for predicting the impact on them due to the spread of suspended sediments and the damage to benthic habitats due to dredging and reclamation. In consideration of the characteristics of the sea area, we divided the survey items of the marine physics into essential items and supplementary items. In predicting the impact of marine physics, various methods for major issues such as seawater circulation, suspended sediment and bottom sediment transport, water temperature and salinity diffusion, seawater exchange, wave transformation, harbor tranquility, and shoreline change were presented. The research results will contribute to protect the marine environment by inducing more systematic and scientific surveys, impact assessments, and mitigation in the EIA process.

The sediment makes up the sea floor and plays an important role as a habitats for living things in the sea. However, pollution of coastal sediment due to internal and external factors such as inflow of contaminants from land and self-pollution becoming more serious, the needs for management of sediment that play an important role in ecology, is increasing. In particular, the review and evaluation of the effects of sediment in marine development projects including reclamation and dredging, have significance in terms of proactive protection and management of surrounding ecosystems. This study proposed the improvement measures for marine sediment management standards on the sea area utilization consultation for the development of public water. For the purpose, The evaluation and management standards of domestic and overseas marine sediments were reviewed and compared. The sediment environment guidelines under the Marine Environment Management Act of Korea were reviewed. Accordingly, the cases of Canada and NOAA, which have various evaluation standards consist of comprehensive factors, were analyzed. For analysis of operational cases, the port and fishing port development projects for the last five years (2016-2020) that are considered to have the greatest impact on sediments among the sea area use consultations were also reviewed. Finally, this study suggested that the assessment factors for ecological hazards and potential human risks should be considered in the sediment environmental standards in the sea area utilization consultation system.

The addition and evaluation of health impact items in Environmental Impact Assessment document are written in hygiene and public health items only for specific development projects and are being reviewed. However, after the publication of the evaluation manual on the addition and evaluation of health impact items in 2011, there is a demand for continuous methodology and improvement plans despite partial improvement. Therefore, in order to propose a methodological improvement of the evaluation manual, this technical paper identified detailed improvement requirements based on the consultation opinions on hygiene and public health items, and investigated and suggested ways to solve this problem by reviewing the contents of the research so far. As for the improvement requirements, the contents related to mitigation plan, post management, effect prediction, assessment, and present-condition investigation were presented in Environmental Impact Assessment documents for the entire development project at a frequency of 93%, 85%, 80%, 74%, and 67%, respectively. Particularly, the detailed improvement requirements related to mitigation plan consisted of an establishment direction and a management of development project. Considering the current evaluation manual and the frequency of improvement requirements, this paper proposed concrete methods or improvement plans for major methodologies for each classification of hygiene and public health items. Furthermore, a comprehensive evaluation methodology related to whether a project is implemented was proposed, which is not provided in the current assessment manual.

The present study is a preliminary attempt to effectively incorporate the environmental issue of coastal erosion into the environmental assessment process of Korea. We assess the status of the environmental assessment on coastal erosion for the previous development plans and provide potential directions for the improvement. The considerable project plans should be screened for the impact of coastal erosion, which occupies about 20% of the total project plans reviewed, and the ratio increased with project scale. In addition to screening process, most process including scoping, baseline study, impact assessment, and follow-up need to be improved. The potential directions of improvement are provided in terms of appropriate guideline development, employment of cumulative impact assessment, follow-up improvement and rearrangement of the preparation regulation of environmental assessment. Emphasis is given for follow-up process to review post-monitoring period, to employ science compensation, and to consider the establishment of relevant institution. Final suggestion is made for the establishments of comprehensive national plan to manage coastal erosion and streamlined environmental process from strategic to project levels based on the national plan.

바닥마감재료가 다른 여름철의 찬바닥이 인체피부온도 및 온열적 쾌적감에 미치는 영향을 검토하기 위하여, 주위벽 및 천장의 온도를 기온과 거의 같게 한 항온실을 이용해서 바닥에 앉은 자세, 의자에 앉은 자세, 서 있는 자세별로 검토했다. 그 결과를 요약하면 다음과 같다. (1) 평균피부온도는 기온이 낮고 수온이 낮을수록 낮았다. Carpet 마감재료는 서 있는 자세, 바닥에 앉은 자세의 평균피부온도가 낮고 의자에 앉은 자세가 높았다. Cork 마감재료가 Carpet, Flooring 마감재료에 비해 평균피부온도가 낮았다. (2) 온냉감평가는 흑구온도가 낮게 되면$\ulcorner$중성이다$\lrcorner$혹은$\ulcorner$서늘하다$\lrcorner$쪽으로 평가하고, Cork, Carpet, Flooring 마감재료의 순으로 $\ulcorner$서늘하다$\lrcorner$쪽으로 평가 하였다. (3) 쾌적감평가는 바닥에 앉은 자세와 서 있는 자세가 의자에 앉은 자세보다 쾌적한 것으로 평가하였다. 마감재료는 Cork, Flooring, Carpet 순으로 쾌적하다고 평가 하였다. (4) 바닥마감재료에 대한 평가는 바닥에 앉은 자세의 경우, Carpet 마감재료는$\ulcorner$차가운$\lrcorner$$\ulcorner$습기찬$\lrcorner$의 평가점수가 높고, Cork 마감재료는$\ulcorner$평활한$\lrcorner$$\ulcorner$차가운$\lrcorner$$\ulcorner$감촉이 좋은$\lrcorner$$\ulcorner$딱딱한$\lrcorner$의 평가점수가 높고, Flooring 마감재료는$\ulcorner$평활한$\lrcorner$$\ulcorner$탄력성이 없는$\lrcorner$$\ulcorner$딱딱한$\lrcorner$의 평가점수가 높았다.$\ulcorner$따듯한$\lrcorner$-$\ulcorner$차가운$\lrcorner$의 평가는 바닥온도의 영향을 받아서, Cork, Flooring 마감재료가 Carpet 마감재료보다$\ulcorner$차가운$\lrcorner$의 높은 점수평가를 하였다. (5) Carpet 마감재료는 평균피부온도가 34$^{\circ}C$를 넘어도$\ulcorner$약간 시원하다$\lrcorner$는 평가이고, 서 있는 자세와 의자에 앉은 자세가 바닥에 앉는 자세보다 쾌적하다고 평가한다. Cork 마감재료는 3자세 모두 평균피부온도 33~34$^{\circ}C$의 사이에서 가장 쾌적하다. Flooring 마감재료는 온열적중성, 쾌적감의 중성의 평가가 많다. 이상의결과를 종합하면, 찬바닥이 인체에 미치는 영향은 바닥마감재료로는 Cork, Flooring이 보다 좋은 평가를 하였음으로, 여름철 바닥마감재료로서는 Cork, Flooring 마감재료가 바람직하다고 생각된다. 자세별로는 서 있는 자세는 바닥에 앉은 자세와 거의 같은 경향을 보이고, 의자에 앉은 자세는 바닥에 앉은 자세와 서 있는 자세 만큼 영향을 받지 않았다. 이후 실험결과를 중심으로 찬바닥의 경우, 보다 쾌적한 온열환경범위를 제안하려고 한다.

Recently, soil has been recognized as a crucially important resource that even can change the quality of life. Also, recent studies have gradually mentioned the importance of assessing soil impact induced by development plans and projects. In this study, after detailed soil assessement items were selected from our national environmental policies and international agreements, they were tested for the long-term dam construction planning in order to ensure more suitable implementation of strategic environment assessment(SEA). We found that soil resources can be impacted by diverse factors such as soil erosion, soil organic matters, soil moving, soil biodiversity, and others. Such detailed factors are found to be overlapped with the pervious EIA factors. Accordingly, additional studies would be required for finding out more reasonable connection between assessment factors during any SEA progress.
