Various strategies and management plans have been established in order to conserve water quality as well as ecosystem, prevent deterioration of scenic area, and more importantly, retain drinking water securely. However, due to the introduction of numerous small-scale development projects on the waterside area outside protection area of source water and reparian area, river water quality and landscape are severely deteriorated. In this study, We analyzed the expected environmental impacts on the ecosystem, topograph, geology, landscape, water quality according to development type, and assigned different environmental points to each development type depend on environmental impacts, which is able to divide small-scale development project into three categories such as projects with rigorous review, projects with general review and projects with simple review. Finally, we suggested the appraisal basement is to avoid or minimize the expected environment impacts of the small-scale development projects in riparian areas so that make them sustainable development by reasonable restriction.

Northeast Asia including China, Japan, Mongolia, Russia, DPRK and ROK, is a geographically close region that falls under the same environmental influence. Recently the region is not only facing serious domestic environmental problems with rapid economic growth, but also confronted with transboundary environmental problems and associated conflicts between countries. Unfortunately, Northeast Asia lacks a solid environmental management system among countries to deal with transboundary and other environmental issues. Transboundary Environmental Impact Assessment (TEIA) can, therefore, be one of the essential systematic measures in which environmental problems between countries would be negotiated. However, it would be necessary to have an indepth discussion of what we have to do first for implementing TEIA system in the region, and how to operate it while customizing each Northeast Asian country with different EIA system and socioeconomic circumstance. All these cannot be decided in a short time, and we need to invest enough time for discussing and considering them from various aspects. Recently, the Korean government declared "Eurasia Initiative". The initiative proposes important developing projects and ultimately plans to build a peaceful community throughout Eurasia based on comprehensive cooperation. The initiative aims to increase exchanges in transportation, energy and agricultural sectors to achieve the goals. In this regard, implementing TEIA in Northeast Asia is urgently needed and we have to prepare the strategy for introducing TEIA mechanism. Based on the results of 10 year experience on TEIA projects conducted since 2004, we suggest double-track approaches for developing TEIA mechanism. We continuously need to make an effort to establish a regional TEIA mechanism that all countries legally join, and simultaneously we also have to prepare a process to carry out TEIA for upcoming projects based on bi- or multi-lateral agreements. Practical solutions such as conducting pilot TEIA with relevant countries and developing TEIA guideline for the region could be the first step.

This research tried to suggest a method of DB construction in the field using evaluation variables and Mobile GIS focusing on Changwon City as a leading study to encourage walking and biking in everyday life. First, twenty evaluation variables of WEs(walking environments) were selected through the literature review, and also scored separately. Second, the field survey-DB of each variable was built effectively using Mobile GIS. Finally, WEs were evaluated synthetically based on the obtained data. The results of this research are summarized as follows. While the WE of the zones located in the fringe of Changwon square were generally got a high score as over 42, other zones located in detached or row house area were evaluated relatively highly bad. Findings from this research will help in determining the zone required improvement of WEs or easy access to main destination such as a park, shopping center, school, etc. and also selecting variables of WEs, needed an intensive improvement, in the selected zone after comparing the results of field and questionnaire survey. Furthermore, those will be used as a means of decision making support for planing, designing and maintaining of WEs to promote people's physical activity in their daily lives.

최근 수문자료에 비정상성이 관측됨에 따라 비정상성 지역빈도해석에 대한 연구가 진행되고 있다. 홍수지수법 (index flood method)은 지역빈도해석에서 가장 널리 사용되는 방법으로 각 지점의 특성을 반영하는 홍수지수 (index flood)와 지역적 특성을 대표하는 성장곡선 (growth curve)을 통해 확률수문량을 산정하며, 비정상성 지역빈도해석의 경우 홍수지수법 내의 요소들을 시간에 대한 함수로 정의함으로써 비정상성을 반영한다. 본 연구에서는 다양한 형태의 비정상성 홍수지수법을 통해 비정상성 지역빈도해석을 수행하고 각 방법에 따른 성능을 비교하였다. 이를 위해 경향성을 가지는 매개변수를 포함하는 비정상성 분포형을 모분포로 가지는 자료를 생성하였으며, 이를 기반으로 다양한 경향성을 가지는 자료들로 지역을 구성하였다. 구성된 지역에 대해 동질성 검토를 수행하여 비정상성 자료들이 포함된 지역의 동질성을 확인하였으며, Monte Carlo 모의실험을 통해 각 비정상성 홍수지수모형에 대한 확률수문량의 RRMSE와 RBIAS를 산정하여 성능을 평가하였다.

Purpose: The aim of this study was to assess the food environment, particularly focusing on restaurants in three areas (Suwon city, Hwaseong Byeongieom-dong, and Bibong-myun). Methods: A total of 662 persons were surveyed on customers' perceptions of the food environment in restaurants. A structured questionnaire composed of 30 questions on 7 factors, sanitation (4 items), displaying information (5), food quality (12), information on nutritional and healthy food choice (6), restaurant's accessibility (1), availability (1), and affordability (1) was used. In addition, an expert assessment of restaurant sanitation, and information on nutritional healthy food choice was conducted through visiting 126 restaurants. Results: Scores (range of score : 1~7) for each factors assessing the restaurant food environment were 5.06 for sanitation factors, 5.05 for displaying information factors, 5.13 for taste appearance factors, and 4.35 for healthy menu factors. Informations on nutritional healthy food choice showed a low rate: only 16.24% of the subjects answered that there is a message encouraging choice of healthy foods and 27.4% answered that menus contain nutritional information. Significant differences in food environment were observed by region (city, town, rural). The restaurants food environment in the rural area turned out to be poorer than that of the other two areas. In comparison of customer perception and expert assessment, significant differences were observed for 'Employee appearances and uniforms are clean and tidy' (p < .05), and 'There is a message encouraging the choice of healthy foods' (p < .05). Conclusion: This study provided evidence for differences of restaurant food environment by regions. In the rural area, there is a problem in restaurant's accessibility, availability, and affordability because of a lack of variety in menu items and restaurants. This results suggest that there is a need for more healthy food restaurants in the rural area.

기후변화로 인해 많은 경우 강수량은 증가할 것으로 전망되지만 시공간적 편차 또한 커짐으로써 가뭄 위험은 증가할 것으로 예상된다. 가뭄 위험도 평가는 강수량, 유출량 등 수문자료로부터 추출한 가뭄변량의 빈도해석을 통해 이루어질 수 있다. 빈도해석의 대상이 되는 수문변량의 통계적 속성이 일정하게 유지되는 정상성의 가정은 기존 빈도해석 방법의 핵심이 되지만, 최근 기후변화로 인한 수문변량의 통계적 특성 변화가 발생할 것으로 예상되기 때문에 이러한 비정상성의 특성을 빈도해석 시 고려할 필요가 있다. 자료의 비정상성을 평가하는데 짧은 기록을 갖는 자료로부터 변화 추세를 신뢰성 있게 평가하는 것은 어려움이 크다. 이러한 점에서 지점자료를 통합적으로 활용할 수 있는 지역빈도해석 절차 도입을 통해 해석 결과에 신뢰성을 확보하는 것이 합리적이다. 본 연구에서는 유역단위에서 가뭄의 지속기간과 심도 사이의 상호의존성을 고려하기 위해 이변량 Copula 함수 기반 가뭄 지역빈도해석을 도입했으며, 두 가뭄변량의 주변확률분포의 매개변수는 시간에 따른 함수로 가정하였다. 모형의 모든 매개변수는 계층적 Bayesian 모형을 통해 동시에 추정하였다. 최종적으로 주어진 가뭄빈도에 해당하는 시간에 따라 변화하는 가뭄 위험을 평가하였다.

The prime objective of this study is to analyze tourist's behaviors and satisfaction of the Gwangneung area and get a reading on the tourist's socio-economic traits and the propensity of activities. In addition, it highlights surveys of the tourist's consciousness of cultural, ecological and environmental tourism resources available in the Gwangneung area and the possibility for sustainable development and ways to make the most of these resources. This study found that even though Gwangneung is mostly a place for one day family outings. the tourist's demand for actually unreachable ecological resources is high while existing cultural tourism resources have less than the expected drawing power. It was also found that tourists recognize the need for preservation of the tourism resources of Gwangneung and its potential for further sustainable development. In particular, most tourists to Gwangneung are relatively satisfied with the status of preservation of its cultural and ecological resources and environment On the other hand, accessibility, tourism facilities, and management are estimated at less than desired. Gwangneung would benefit by making efforts for the positive use of its tourism resources and improvement of convenience facilities, management and operation.

지역빈도해석은 대상 지점의 관측자료만을 사용하는 지점빈도해석과 달리 지역구분을 통해 정의된 동질지역 내에 포함된 모든 지점의 자료를 사용하여 보다 정확하고 신뢰할 수 있는 확률수문량을 산정할 수 있는 방법이다. 지역빈도해석의 절차는 크게 지역구분인자를 이용한 동질지역구분과 홍수지수모형의 적용을 통한 확률강우량 산정으로 나눌 수 있다. 본 연구에서는 지역구분에 사용되는 지역구분인자가 지역빈도해석의 확률강우량 산정에 미치는 영향을 알아보기 위하여 지역구분인자와 확률강우량 산정결과와의 상관성을 분석하고자 한다. 먼저, 동질지역 구분을 위해 지형적 특성과 수문학적 특성을 나타내는 지역구분인자를 선정하였으며, 군집분석을 통해 동질지역 구분을 수행하였다. 구분된 동질지역에 대해 지역성장곡선을 추정하고 홍수지수모형을 통해 지점별 확률강우량을 산정하였다. 지역빈도해석을 통해 산정된 확률강우량의 지점빈도해석 대비 증감률과 동질지역구분에 사용된 지역구분인자와의 상관성분석을 통해 지역빈도해석의 확률강우량 산정에 영향을 주는 지역구분인자를 확인하였다.
