Since the tourism complex development projects is promoted for areas with good natural environment and excellent landscapes, it has s significant environmental impact on the surrounding area. Therefore, this study investigated the current status and various environmental influences of tourist complex based on environmental impact assessment reports from 2012 to 2021. Based on the results of the current status analysis of the development projects, EA-INDEX for the tourism complex development projects was developed and applied to comprehensively and quantitatively analyze various environmental impacts. Through this, we investigated eco-friendliness of the development projects by year in the natural environment conservation sector, resource conservation sector, and living environment protection sector. As a result we found that the tourism complex development projects were carried out in a way that increases eco-friendliness over the past ten years, especially in in the natural environment conservation sector. On the other hand, in the case of resource conservation, it has been confirmed that eco-friendliness is decreasing, so it is necessary to make efforts to improve it when establishing new development plans in the future. It is expected that the result of this study will be useful for identifying the development trend and environmental impact of development projects. If an analysis is made that synthesizes information such as policy events and social issues related to development projects in the future, it is also expected that a broader explanation will be possible to identify trends in development projects using EA-INDEX.

Indoor noise environment is an important factor when it comes to occupants comfort, especially in cafe. Results of the survey, 33.9% of occupants were feel unpleasant and sensitive about noise environment. Noise in cafe fluctuate depending on the finishing of both wall and ceiling, volume of the room, and the number of occupants in the room. Therefore, the noise meter device was used for measurement of various under conditions. Also, the subjective assessment of occupant noise was conducted through questionnaires. When the interior finish was exposed concrete, the maximum value of the noise measurement was 66.6 dB and the minimum value was 63 dB, respectively. Also, the result of subjective assessment of unpleasant noise were 5.43 and 4.96 point of 10 point of noise and echo, respectively. Otherwise, the interior finish was gypsum board, the maximum value of the noise measurement was 73.8 dB and the minimum value was 60.4 dB, respectively. Also, the result of subjective assessment of unpleasant noise were 3.88 and 3.95 point of 10 point of noise and echo, respectively. The results of the study showed that the noises and echoes in the cafes were lower than when did not.

In this study, we applied DRASTIC and SINTACS models for the assessment of groundwater vulnerability to Buyeo-eup area in Buyeo-gun, Chungcheongnam-do, Korea. Currently, DRASTIC model is a main tool for the assessment of groundwater vulnerability, which has been widely applied for the multiple purposes related to local developments, construction projects, groundwater investigations, etc. since 1980s. Because DRASTIC model has been the sole tool used for the domestic environment, there has been doubt about the degree of reliability of the model, and a benchmark model has been sought by the many practitioners. The objective of this study is to check the applicability of SINTACS model to domestic environment, which is the first attempt in Korea as far as authors understand. The comparative results show that the DRASTIC assessment underestimates groundwater vulnerability of the aquifers composed of fractured bedrocks while that from the SINTACS model is relatively higher. Through this study, it is expected that SINTACS model serves as a reasonable alternative of DRASTIC model where the subsurface is composed of more than two different media such as fractured rocks and alluvium.

The study area investigated in this research is Hwaseong city, Gyeonggi-Do where small scale development is currently in progress. For the last three years, we carried out the environmental and ecological assessment by using data from The Ministry of Environment and Han River Basin Environmental Office. Most of development works in Hwaseong city, Gyeonggi-Do are small scale developments which are related with factory and distribution complex based on individual laws and regulations. However, environmental and ecological assessment is not being sufficiently reflected beforehand. Especially, because the development takes place mainly in the outskirts of the city, the fine forest is continuously being damaged. We analyzed changes in green zone caused by the developments. As a result, the percentage of original green zone was decreasing while the percentage of artificial green zone was increasing. We should maintain the percentage of the original green zone in order to conserve natural environment. In the past three years, the damage of the DGN (Degree of Green Naturality, 7) area that has high conservative value was little, but, there was serious damage in the area of DGN 6. In order to conserve natural environment, political and institutional investigation should be seriously carried out for mitigation of environmental and ecological damages.

Purpose: As the concerns for the environment are gradually prioritized, increasing interests of environment-friendly buildings are drawn. The Green Standard for Energy & Environmental Design (G-SEED) has been strengthened. However, there are no specific assessment criteria that reflect the special situation of healthcare facility. UK, US and Japan have green building certifications specially designed to evaluate sustainable healthcare facilities. This study has been started in order to provide basic information for developing assessment criteria for healthcare facilities in Korean Green Standard for Energy and Environmental Design. Methods: In this study, we investigated three foreign green building certifications and compared their assessment system and criteria for healthcare buildings. Results: Each of the three foreign certification standards showed the difference in the system, but all contained the contents specific to healthcare facilities. Evaluation items were affected by regional cultural environment and also medical environment. Patient safety and integrative planning were the most important assessment contents. Implications: Based on this analysis, Korean Green Standard for Energy & Environmental Design for healthcare facilities will be developed.

EIA should be regarded as an aid to improve the decision making processes because it seeks public opinion and external knowledge in order to ensure the maximum degree of fairness and balance in the final decision as much as possible. According to the above benefits, various decision making systems containing EIA concepts were developed in the area of ground water, traffic, disaster or accident and environment in Cheju Island. But because the development of various decision making systems can be the cause of new impact, it was studied the cause and impact of their development. The major reasons for developing the various decision making system like EIA are the lack of the consideration for the impact of project when it is selected project fulfilling EIA and the increase of the effort for the improvement in the professional quality for one subject without the comprehensive assessment among the subject related to environmental impacts. And the development of the various decision making systems like EIA has caused the several impacts like cost elavoration, the relay of project period, etc. Therefore, after it is improved the problems of present EIA on the comprehensive assessment, the various decision making systems like EIA should be integrated in EIA decision making system.

Current water quality standard (WQS) in Korea is based on the protection of human health, not considering the protection of aquatic organisms. Most of chemicals can be toxic to ecological biota as well as human. Health of aquatic biota is closely related to the human health via food chain, therefore ecological risk based-WQS needs to be developed to protect the aquatic ecosystem. In this study, we selected the 31 chemicals in the Project entitled 'Development of integrated methodology for evaluation of water environment'. The methodology for calculating water quality criteria was derived from the Australian and New Zealand processes for deriving guideline trigger value for aquatic ecosystem. The available ecotoxicity data were collected from US EPA's ECOTOXicology Database (ECOTOX), TOX-2000 Database, European Chemicals Bureau (ECB)'s International Uniform Chemical Information Database (IUCLID) and Environmental Protection Agency (US EPA)'s report 'Ambient Water Quality Criteria (AWQC)'. The aquatic toxicity data for the Korean species were selected for risk assessment to reflect the Korean water environment. The monitoring values were calculated from the water quality monitoring data four main Korean rivers. We suggested the order of priorities of chemicals based on ecological risk assessment. We expect that these results can be useful information for establishing the WQS for the protection of aquatic ecosystem.

The Korea Adaptation Center for Climate Change (KACCC) located in Korea Environment Institute has serviced a climate change vulnerability assessment support tool (VESTAP) since 2014 in order to help local governments to establish their own adaptation plans. Owing to its easy usage, the VESTAP has been utilized by not only local governments but also academia for examination of climate change vulnerability in various fields. However, the KACCC has not suggested a standard usage how to compose indices for climate exposure, sensitivity, and adaptation capacity which are main components of vulnerability although the KACCC manages operation and application of the VESTAP. Many users had no choice but to compose indices based on their own interpretation on the components of vulnerability. This technical note suggests the standard usage of VESTAP by reevaluating some vulnerability assessments previously developed. This may help users to correctly compose indices for climate change vulnerability assessment, and may minimize possibility of inter-user inconsistency in definition of vulnerability assessments.

The purpose of this study is to suggest improvements of Eco-Natural map preparation guideline by presenting assessment methods that can be applied to the result of river ecosystem health survey and assessment, using the Geographic Information System. The area for studying is the main stream of the Hwang River where is easy to collect data and available to compare before and after of river assessment. It was reevaluated by reflecting the result of river ecosystem health assessment of the Ministry of Environment. As the result, Eco-Natural map of the study area reflecting the river assessment, the changes in the area ratio by grade have been increased from 1.14% to 14.03% in the first-grade and from 24.64% to 43.91% in the second-grade. It is considered to present more realistic grade due to the assessment of the rivers that have not been reflected in the meantime. Consequently, the result of this study will be useful for establishing the development projects on the rivers, providing the foundation for more realistic and active protection.

We conducted human risk assessment for exposure to inhalation of chemical substances emitted from the storage tanks of petroleum refineries. To assess human risk, this study calculated chemical emissions from the external floating roofs on storage tank at petroleum refineries, as well as concentrations thereof in the ambient air using the K-SCREEN model, and then determined risk in accordance with the Reference Concentration (RfC) values and Inhalation Unit Risk criteria developed by the US Environmental Protection Agency. The results indicated that non-carcinogenic chemicals have a hazard quotient of less than 1, meaning they have an insignificant effect on human health for residential areas near the storage tanks. Among the known carcinogens, the hazard risk for benzene slightly exceeded $10^{-6}$, indicating the need for corrective reduction measures. The methodology for health impact assessment devised herein provides findings useful in decision making for policy makers and the general public with respect to construction of industrial complexes. However, the methodology proposed herein does have limitations, including discrepancy in results induced by use of U.S. data (due to the lack of usable domestic data). More systematic studies from related researchers will be needed to address these issues and produce more reliable outcomes.
