In this study, the information from environmental impact statements was converted into spatial data because environmental data from development sites are collected during the environmental impact assessment (EIA) process. Spatiotemporal big data were built from environmental spatial data for each environmental medium for 2,235 development sites during 2007-2018, available from public data portals. Comparing air-quality monitoring stations, 33,863 measurement points were constructed, which is approximately 75 times more measurement points than that 452 in Air Korea's real-time measurement network. Here, spatiotemporal big data from 2,677,260 EIAs were constructed. In the future, such data might be used not only for EIAs but also for various spatial plans.

This paper aims to study the influence of environmental attitudes on the choice of non-professional investors. It highlights the role of environmental performance assurance on investment judgments. This choice is due to the motivation and importance that investors place on the disclosure of environmental information. The main purpose of the research is focused on the empirical approach justified by the use of a questionnaire addressed to 200 non-professional investors. The results show that attitudes towards the environment do not correlate with the importance that gives this category of investors to the environmental information.. Subsequently, the results prove that the disclosure of an environmental assurance report has a positive impact on investment judgments independently of their appreciation of the environmental information concerning that of financial order.

The purpose of this research is to examine the user experience design that effectively exhibits botanical information through a virtual habitat built with 3D modeling and scanning data for the conservatory at Seoul Botanic Park. Seoul Botanic Park's conservatory contains environmental and ecological information on the wide spectrum of diverse plants under twelve cities all over the world. However, the exhibition method, which focuses on maps and information boards, has limitations in delivering diverse plant and habitat information to visitors. Virtual and augmented reality can be used as an effective tool for educating and experiencing the contents of various plant species as it can convey the ecological and environmental conditions of the habitat and local culture at diverse levels. This study experimented with constructing virtual habitats using the Unreal Engine and effectively communicating various botanical information through the interaction. With the introduction of a virtual habitat, we intend to enhance the user experience of park visitors and ultimately explore the possibility of using virtual and augmented reality to convey multi-layered environmental and ecological information of landscape.

환경문제는 단순히 개별적 원인 및 단일과정을 통하여 발생하는 것이 아니라 복합적 원인과 영향으로 발현된다. 기존의 환경정보는 개별 구축 목적에 맞도록 수치 위주(통계)로 생산되었으며 더욱이 개별 시스템(국가상수도정보시스템 등 17개)에 관련 인자들이 산재되어 있어 다양한 원인 및 피해를 고려해야 하는 환경문제 해결에 많은 시간과 노력이 허비되어 즉각적 적시적 대응이 이루어지지 않는다. 이러한 한계점과 문제점을 인식하여, 환경공간정보를 통합적으로 제공하기 위한 국가환경지도시스템 구축 및 정책적 활용 방안에 대한 연구를 수행하였다. 첫째, 국내 산재되어 있는 환경공간정보 현황을 분석하기 위해 환경부 실 국, 산하 및 유관기관의 시스템 및 환경공간정보 담당 부서의 총 2,701개 업무 자료를 분석하여 총 275개(비점오염원 관리 확대를 위한 환경정보 구축 등)의 환경정보와 관련된 업무 및 정보현황 자료를 선별하였다. 둘째, 환경정책 수립 및 이행을 지원하기 위해 환경정보 관련 업무 현황을 분석하여 총 64건(백두대간, 정맥 및 기맥 현황 및 보전지역 등)의 국가환경지도시스템 세부 업무지원 주제도를 도출하고, 도출된 업무지원 주제도의 우선순위를 선정하였다. 셋째, 업무지원 주제도 구축을 위한 정보 연계를 위해서 환경부 및 산하 유관기관의 전체 17개 시스템 및 환경 주제도를 분석하였다. 분석 결과 활용 가능한 공간정보 총 1,314개 및 세부 항목 총 39,331개의 공간정보 기반의 활용 가능한 데이터베이스를 선별하고 표준화 방안을 수립하였다. 넷째, 국가환경지도시스템의 실질적 구축을 위한 단계별 이행방안을 제시하였다. 마지막으로 향후 국가환경지도시스템을 기반으로 하는 정책적 활용방안을 제시하였다. 국가환경지도시스템이 효율적으로 구축되면 산재된 환경정보를 공간 정보 기반의 공동 활용 데이터베이스로 구축할 수 있고 또한 환경정책 수립에서 위치 기반의 정량적 정책 수립을 지원할 수 있을 것으로 사료된다.

Clustering is the process of grouping the data into clusters so that objects within a cluster have high similarity in comparison to one another. In this paper we used k-means clustering of several clustering techniques. The k-means Clustering is classified as a partitional clustering method. We analyze 2002 Gyeongnam social indicator survey data using k-means clustering techniques for environmental information. We can use these outputs given by k-means clustering for environmental preservation and environmental improvement.

Purpose In this study, the relationships among environmental information exchange with suppliers(EIES), green collaboration with suppliers, green learning by environmental information, the adoption of green supply-chain management techniques(AGSMT) (i.e., the green purchasing, product design and production, and the recovery of extra facilities and inventories), environmental performance, and the organizational performance of a firm were empirically investigated. Design/methodology/approach Data for this study were drawn from a survey of the current status of EIES levels and AGSMT usage observed in Korean manufacturing firms. In total, 500 organizations were randomly selected from a population of about 1,000 firms that are listed on the Korean stock market. In order to collect empirical data, this research administered questionnaires with the sample firms. Only chief production executives were selected as respondents. A questionnaire with a cover letter was mailed to each respondent. The survey was conducted during a 3-month period between March 2015 and June 2015. Finally, 78 valid data of the sample firms were collected. Findings The results of this study showed that EIES positively affects the green corporation and learning. According to the results, it was observed that both green corporation and green learning have a positive impact on the levels of AGSMT(i.e., the green purchasing, product design and production). It was also demonstrated that AGSMT has a direct positive impact on environmental performance. In examining the effects of environmental performance on the organizational performance of a firm, significant impact was found.

Climate change is considered a severe global problem closely related to carbon storage. However, recent urbanization and land-use changes reduce carbon stocks in terrestrial ecosystems. Recently, the role of protected areas has been emphasized as a countermeasure to the climate change, and protected areas allow the area to continue to serve as a carbon sink due to legal restrictions. This study attempted to expand the scope of these protected areas to an evaluation-based environmental spatial information theme map. In this study, the area of each grade was compared, and the distribution of land cover for each grade was analyzed using the Ecological and Nature Map, Environmental Conservation Value Assessment Map and Urban Ecological Map of Sejong Special Self-Governing City. Based on this, the average carbon storage for each grade was derived using the InVEST Carbon model. As a result of the analysis, the high-grade area of the environmental spatial information generally showed a wide area of the natural area represented by the forest area, and accordingly, the carbon storage amount was evaluated to be high. However, there are differences in the purpose of production, evaluation items, and evaluation methods between each environmental spatial information, there are differences in area, land cover, and carbon storage. Through this study, environmental spatial information based on the evaluation map can be used for land use management in the carbon aspect, and it is expected that a management plan for each grade suitable for the characteristics of each environmental spatial information is required.
