Backgrounds: With the globalization of drug development, multi-regional clinical trials (MRCTs) have emerged to facilitate rapid availability of medicines to patients worldwide. The present study aimed to has explored attitudes and perceptions towards adopting the Korean MRCT guideline. Methods: An online survey, consisting of 16 questions, classified into two subjects, was administered to stakeholders in Korea. Most quantitative components were measured using the Likert scales. A content analysis of the qualitative components was carried out to identify the keywords in open-ended responses. Results: A total of 94 survey responses were analyzed: 51 participants from pharmaceutical companies, 11 from clinical research organizations, and 21 from clinical trial centers. The content of the guideline was rated as appropriate for clarity, acceptability, and applicability (96.8, 96.8, and 93.6%, respectively). The local environmental impact of the systemic/political, academic/technical, and industrial/economical aspects of the guideline was rated as appropriate at 95.7, 97.9, and 91.5%, respectively. The suggested adoption period was 1~2 years (40, 42.6%). The concept and individuals' domestic circumstances were the key problems affecting the clarity, applicability, and local environmental impact of the guideline. Conclusion: The Korean MRCT guideline was well-developed. Their overall impact on the local environmental impact of MRCTs in Korea was expected to be beneficial, but methods are needed to minimize the negative impacts. The findings of this study can inform the priorities for the future adoption of the guideline in Korea.

Korea has made the rapid economical development under the condition with the high population density and low available land. In this context, conservation of land environment, connected directly with living quality of human, has mostly ignored. Prior Environment Review System(PERS) is the one to investigate the locational validity, environmental impacts, harmony with surrounding environment, from the early stage of administrative plan or development project. PERS was amended to include SEA(Strategic Environment Assessment) system on June 1, 2006. But, several problems, including the loss of administrative ability, cost, and time, have been appeared, since the system is applied to all administrative plans without any distinction and plans or projects are delayed generally. In this study, the weaknesses of PERS were indicated through the comprehensive analysis including literature survey, study of legal and internet database, and the recently published PERS reports. Based on that, the improvement schemes were suggested to be harmonized with the nature of SEA. This study was mainly focused on a PERS for the designation of conservational area of hot-spring wells, conducted by authors.

The purpose of this study is to consider for the introduction of the school eco-audit system as an educational method for sustainable development. First of all, the concept and objective of the education for sustainable development(ESD) are reviewed in order to advance a theory on school eco-audit system. ESD which under the premise of global inter and intra generation justice, resolves to address a mixture of ecological, economical and social aspects, as well as safeguarding limited resources and protecting the environment from pollution and energy. In order to effectively structure uncoordinated environmental activities carried out by schools, the introduction of school eco-audit system in Korea is suggested, which as the model for long-term development, has since been integrated into the school's programme. Activities related to waste, heating, electricity and water are run by a 'Management Team'. By combining all 3 fields of action - i.e. establishing basic organizational conditions, education, and individual ecological measures - the eco-audit proves to be the key to success. In particular, administration agency and method, institutional improvement are presented.

In general, lots of containers including various dangerous materials are transported to the port located in big cities such as Busan where massive residents live. Thus, it's really important how to make the emergency response for the leak accidents of dangerous materials and evaluate the direct or indirect damages to adjacent areas. In this study, in order to make reasonable emergency plans, CA (Consequence Analysis) is employed after selecting a key hazardous and noxious material, hydrogen fluroide. This material accounts for the third largest portion of cargo volume among all dangerous materials and can cause a huge damage in case of leakages. As a case study, Busan North port is selected as a test port since the portion of dangerous materials is higher than that of other ports in Busan. It is assumed that 1 ton of hydrogen fluoride is spilled at Busan North port. CA is performed to assess the impact of this accident. Throughout CA, the ERPG-2 range of a leak accident can be evaluated and this result can be used for decision making tools for mitigating the impact of a leak accident. To mitigate the damage of this accident, suitable a protective equipment and resident evacuation procedures should be prepared. Finally, this study can provide a systematic approach to make the emergency plan for reducing economical and personal losses.

Human lifestyle is affected by the agricultural development in the last 12,000 years ago. The development of agriculture is one of the reasons that global population surged. To ensure sufficient food production for supporting human life, pesticides as a more effective and economical tools, are extensively used to enhance the yield quality and boost crop production. This study investigated the factors that affect crop production and whether the factors of pesticide usage are the most important factors in crop production using the dataset from Kaggle that provides information based on crops harvested by various farmers. Logistic regression is used to investigate the relationship between various factors and crop production. However, the logistic regression is unable to deal with predictors that are related to each other and identifying the greatest impact factor. Therefore, causal discovery is applied to address the above limitations. The result of causal discovery showed that crop condition is greatly impacted by the estimated insects count, where estimated insects count is affected by the factors of pesticide usage. This study enhances our understanding of the influence of pesticide usage on crop production and contributes to the progress of agricultural practices.

Water supply and sewerage systems are the large-scale urban infrastructure ejecting large amount of environmental load over the life-cycle. Therefore, it is important not only to optimize in the aspect of economical superiority and process efficiency but also to consider earth scale environmental impact. This study aimed to suggest the establishment of life cycle management(LCM) system as an integrated management solution in urban water supply and sewerage systems. As a result, the methodology for LCM system consisting of life cycle assessment(LCA), life cycle cost(LCC), life cycle $CO_{2}(LCCO_{2})$ and life cycle energy(LCE) was developed. Also, several case studies using the latest statistics data of water supply and sewerage systems were carried out to investigate the field applicability of LCM.

Railway is superior to the other land transportation systems in aspects of energy efficiency and environmental problems. Energy efficiency and environmental problems are not considered during a preliminary feasibility study. Investment for railway is low because of low B/C in the economical efficiency analysis during the preliminary feasibility study. The body of this paper studies the data which can reflect environmental problems an assessment of environmental impact. Investment for railway would be higher when main environmental elements are considered before the choice of the railway lines.
