환경적 가치를 보존하고 개발로 인한 부정적 영향을 최소화하기 위하여 환경영향평가 제도가 수행되고 있다. 현재의 환경영향평가의 객관성 강화하기 위해 데이터 기반으로 전환이 필요한 시점이다. 또한 국가 차원의 다양한 공간정보 제공 및 환경영향평가에 공간정보 연계 가능성을 통해 환경영향평가제도의 공간정보 활용 확대가 요구되고 있다. 그러나 현재 환경영향평가에서 공간정보가 체계적으로 활용되고 있지 않는다. 또한 환경영향평가 업무 종사자(담당 공무원, 환경영향평가서 대행기관, 검토기관 등)들은 공간정보 개념에 대한 이해도가 부족하여 효율적으로 활용하는데 한계가 있다. 이러한 공간정보 활용의 한계점을 개선하기 위하여 본 연구에서는 공간정보 표준화(좌표, 속성 테이블) 방안을 제안하였다. 이를 위해, 국가 공인의 좌표계 및 표준을 기반으로 표준 좌표계를 제안하였으며, 환경매체별 조사 항목의 데이터 테이블의 기본항목을 9개로 설정하였다. 마지막으로, 전술된 표준화를 실제 환경영향평가 사업에 대하여 시범 적용하였다. 본 연구에서 제안한 표준화 방안은 환경영향평가에서의 공간정보 활용 활성화 및 평가 분야의 범위 확장에 기여할 것으로 사료된다.

The objective of this study were to develop landscape scale ecosystem assessment model, and apply the model for the assessment of the state and change of ecosystem of the study area, Yongin, Korea. Since natural ecosystem of the site has been deteriorated significantly during recent extensive residential development, it is essential to correctly assess ecosystem of the study site. Traditional ecosystem assessment mainly utilizing intensive field survey requires high cost, but the outcome rarely represents spatial pattern of the regional ecosystems. Ecosystem assesment of landscape scale based on landscape ecology can resolve most of the shortfalls of the traditional approach. The research method can be summarized as follows. First, extensive literature review on such topics as spatial pattern of ecosystem, ecosystem assessment of landscape scale, ecological analysis was carried out. Second, a model for the ecosystem assessment of landscape scale emphasizing spatial pattern of ecosystem was developed. This model evaluates three indicators; ecological integrity and biological diversity, watershed integrity, and landscape resilience of 11 watersheds in the study area. Finally, ecological assessment utilizing two sets of indicators, enhancement of and disturbance of ecosystem stability, was carried out. This assessment method is based on Environmental Monitoring and Assessment Program´s Landscape component(EMAP-L) of EPA(1994). The results of this study are as follows. First, the ecosystem assessment of landscape scale of the study area of Yongin, Korea, showed that escosystems of Tanchun01 and Chungmichun01 watersheds had the worst state in the study site in 1991. On the other hand, the ecosystems of Jinwechun01, Kyunganchun02, and Bokhachun01 watersheds had the most stable ecosystem in 1991. Second, ecosystems of Tanchun01, Shingal reservoir, and Kyunganchun01 watersheds were evaluated to be the worst state in the study site in 1996. And, ecosystems of Jinwechun01 and Gosam reservoir watersheds had the most stable ecosystem. Third, ecosystem of Tanchun01 watershed which incudes Suji residential development project site changed the most drastically between 1991 and 1996. The ecosystem of the watershed the most drastically deteriorated due to it´s proximity to Seoul and Bundang new town.

Cumulative effects can be defined as impacts on environment which results from incremental impacts of a proposed project, which covers other past, present, and reasonably foreseeable future actions. The necessity of Cumulative Effect Assessment is that, when there are several projects near the project area, environmental effects of individual project can be larger or smaller than those of individual project without having projects nearby because of synergy, ascending and descending effects. This study was intended to help Environmental Impact Assessment practitioners identify spatial and temporal boundaries during the scoping stage. To do this, literature review of domestic and foreign legislations, guidelines, textbooks and papers related to Environmental Impact Assessment and Cumulative Effect Assessment was accomplished. This study suggests that continuous research be needed in order to identify spatial boundaries for other assessment fields and to develop methodologies for cumulative effect assessment.

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 study investigated elementary students' spatial thinking and visualization when they learned the shape of volcanoes. For this purpose we used GeoMapApp to design instruction program and assessment items. In the instruction, students were asked to connect the floor plan view of Jeju island with the cross-sectional view of the same figure producted by GeoMapApp. Then they were asked to classify four sets of pictures of volcanoes based on the similarities of figures, that is, dome-shaped and shield volcanoes. In the assessment students solved three questions which examined how they connected the plan view and cross-sectional profile of Kilauea, draw cross-sectional profile of Mt. Fuji, and distinguished a shield volcano and dome-shaped one. Students' discourse data during the class were analyzed according to the amount to showing their spatial thinking and visualization. The instruction program using GeoMapApp assisted students to facilitate their spatial thinking for understanding of volcanoes. The outcomes of assessment showed even elementary students had good spatial thinking and visualization. Therefore, we argued spatial thinking and visualization for geoscientific understanding need to be included in the national science curriculum for elementary students.

In this study, a GIS-based park safety assessment index was developed to enable objective park vulnerability assessment through data-based GIS analysis, a safety assessment was conducted by selecting a target site where various parks are operated and applying the park safety assessment index. In addition, a facility management system was developed for efficient management of the park safety assessment to update the park safety and provide a foothold for indirect PPGIS. In the case of the assessment index of the safety rating of the park, it was possible to conclude that the accurate quantitative performance was given to the calculation of the safety grade of the park based on the fact that the facilities are different depending on the environment and the size of the park. In addition, the marking the safety grade of parks, as well as the function to show the safety facilities of parks, a common living area for citizens, the management system is expected to have an impact on promoting the use of parks. In the future, in functions such as reporting of facility failures and verifying civil information are implemented by applying civic group participation programs and crowd-sourcing technologies, it is believed that all facilities as well as parks managed by the local government can be managed more efficiently.

목적 : 본 연구는 편측 공간무시 환자의 평가도구 중 KF-NAP (Kessler Foundation - Neglect Assessment Process)과 지필검사 (직선이분검사, 글자소거검사, 알버트 검사) 사이의 상관관계와 편측 공간무시에 대한 민감도가 높은 평가도구를 알아보고자 한다. 연구방법 : 2014년 9월부터 2015년 9월까지 서울 소재의 병원 재활의학과에 입원한 32명의 뇌졸중 환자를 대상으로 하였다 (남성 19명, 여성 13명, 평균연령 61.8세). KF-NAP과 지필평가는 입원 7일 이내에 시행하였으며, 각 평가도구의 결과 값으로 편측 공간무시 정도를 비교하였다. 결과 : 편측 공간무시 정도는 KF-NAP 93.8%, 직선이분검사 53.1%, 글자지우기 53.1%, 알버트 검사 37.5%로 편측 공간무시에 대한 민감도가 가장 높은 평가도구는 KF-NAP이었다. KF-NAP은 직선이분검사(r=.430), 글자 지우기(r=.641), 알버트 검사(r=.398) 모두에서 유의한 상관관계가 있었다 (p<0.05). 결론 : KF-NAP은 환자의 일상생활 동안 편측 공간무시를 평가하는 도구로써 지필검사에 비해 편측 공간무시의 진단에 더 민감할 뿐 아니라 편측 공간무시의 중증도에 대한 평가가 가능하다. 따라서 편측 공간무시의 평가에 KF-NAP이 유용하게 사용되어져야 한다.

Survivability of naval vessels is defined as the ability to perform functions and missions in a combat environment. Survivability has close relationship with the spatial layout of naval vessels. In order to maximize survivability, it must be considered from the early stage of design. However the existing concept of survivability was intended to be applied to unit vessels. So it was not suitable for assessment of spatial layout results at the early stage of design. In this paper, a simplified assessment method which can evaluate the spatial layout considering the survivability in the early stage of design has been proposed. For this, assessment layers were defined on survivability components such as susceptibility, vulnerability, and recoverability. Assessment layers of each component were overlapped to deduce a survivability layer of spatial layout alternatives. In addition, the proposed method and optimization algorithm were used to derive optimal spatial layout alternatives considering survivability.
