도계지역은 경계하고 있는 시 도와 다층적인 지역적 네트워크가 형성되는 특성 때문에 비도계지역과는 차별화된 전략이 필요하다. 본 연구의 목적은 도계지역으로서 옥천이 갖는 지역적 네트워크 특성을 통근 통학자, 기업, 정부차원에서 분석하고 도계지역의 발전을 위한 정책적 시사점을 도출하는 것이다. 연구결과 옥천은 통근 통학자 네트워크 측면에서 대전과 지역적 네트워크가 가장 강하고, 호남과는 네트워크가 없는 것을 확인하였다. 기업측면에서는 대전, 경기, 충북과, 정부차원에서는 대전(동구, 대덕구)와 경기(부천)와 네트워크를 형성하고 있다. 본 연구는 도계지역을 새로운 정책대상으로 상정하고, 지역 네트워크 연구의 기초자료로서 인구주택총조사의 초광역적 통계데이터를 구축과 경계지역 기초자치단체 간 협력체계를 마련할 것을 제안한다.

This paper proposes an adaptive threshold watershed algorithm, which is the method used for image segmentation and boundary detection, which extends the region on the basis of regional minimum point. First, apply adaptive thresholds to determine regional minimum points. Second, it extends the region by applying adaptive thresholds based on determined regional minimum points. Traditional watershed algorithms create over-segmentation, resulting in the disadvantages of breaking boundaries between regions. These segmentation results mainly from the boundary of the object, creating an inaccurate region. To solve these problems, this paper applies an improved watershed algorithm applied with adaptive threshold in regional minimum point search and region expansion in order to reduce over-segmentation and breaking the boundary of region. This resulted in over-segmentation suppression and the result of having the boundary of precisely divided regions. The experimental results show that the proposed algorithm can apply adaptive thresholds to reduce the number of segmented regions and see that the segmented boundary parts are correct.

In this study, we have simulated regional climate over East Asia using dynamical downscaling For dynamic downscaling experiments for regional climate simulation, MM5method. with 27 km horizontal resolution and 18 layers of sigma-coordinate in vertical is nested within global-scale NCEP reanalysis data with 2.5。${\times}$2.5。 resolution in longitude and latitude. In regional simulation, January and July, 1979 monthly mean features have been obtained by both continuous integration and daily restart integration driven by updating the lateral boundary forcing at 6-hr intervals from the NCEP reanalysis data using a nudging scheme with the updating design of initial and boundary conditions in both continuous and restart integrations. In result, we may successfully generated regional detail features which might be forced by topography, lake, coastlines and land use distribution from a regional climate. There is no significant difference in monthly mean features either integrate continuously or integrate with daily restart. For climatologically long integration, the initial condition may not be significantly important. Accordingly, MM5 can be integrated for a long period without restart frequently, if a proper lateral boundary forcing is given.

This studys concerns with a critical issues of urban and rural integration for rurban development. Todays, many of urban-rural integrated cities are confronted with the negative effects of administrative boundary integration. The first problem is induced from the developmental gaps and different residential demands between the core-city and peripheral-county. The second problem is social-economic and administrative unification costs neglected. The third problem is the environmental pollutions and degradations in peripheral-county by rapid urbanization. The forth problem is the inequality of the public services and regional investments in the urban-rural Integrated cities. The fifth problem is the administrative relation and financial distribution between core-city and residual province when the urban-rural integrated core-city becomes large urban city. The results of the questionnaire analysis as follows. The first point, the preference of administrative boundary integration is different in intra-areas of urban-rural integrated county by it's location. The second point, the diversity of preference of residents depends on theirs job, age, resdential period, education and income level. So, administrative boundary integration must consider the many important factors which affect the socio-economic situations between the core-city and peripheral-county. In conclusion, residents' preference for the admistrative boundary integration depends on their situation without rational approach for macro regional development. In this contexts, comprehensive approach for the urban-rural administrative boundary integration is needed in consistent with rapid change of local government's functions.

본 논문은 스위스 독일 프랑스 접경지역에서의 월경적(越境的) 상호작용과 초경계적 지역정체성 형성여부를 고찰하고자 한다. 먼저 이 논문은 '경계와 접경지역' 에 관한 최근의 연구들을 검토하여, 이 주제에 대한 이론적 토대와 월경협력의 유형을 구축한다. 이를 기반으로 유러리젼 '라인강 상류' 의 월경적 협력과정을 분석하고 본 연구의 사례지역인 '레기오 트리레나' 에서의 일상적인 월경적 이동(통근, 쇼핑, 주택)을 연구한다. 유러리젼 '라인강 상류' 에서의 월경적 협력은 다양한 활동영역을 지닌 여러 위원회에 의해 추진되며 러시아 인형 바부슈카처럼 중층적으로 구성되어 있다. 스위스 독일 프랑스 간의 경제적인 차이는 3국간의 대량 월경이동을 유발한다. 이 논문은 이러한 월경이동을 울만이 제시한 공간적 상호작용의 3대 기반(상호보완성, 이동가능성, 개입기회)에 입각하여 해석해 보았다. 마지막으로 본 논문은 경제적 장벽의 제거가 초경계적 지역정체성 또는 초국경적 공동체 정신을 창출하기에는 충분치 않다는 것을 보여준다.

The initial and boundary conditions are important factors in regional chemical transport modeling systems. The method of generating the chemical boundary conditions for regional air quality models tends to be different from the dynamically varying boundary conditions in global chemical transport models. In this study, the impact of real time Copernicus atmosphere monitoring service (CAMS) re-analysis data from the modeling atmospheric composition and climate project interim implementation (MACC) on the regional air quality in the Korean Peninsula was carried out using the community multi-scale air quality modeling system (CMAQ). A comparison between conventional global data and CAMS for numerical assessments was also conducted. Although the horizontal resolution of the CAMS re-analysis data is not higher than the conventionally provided data, the simulated particulate matter (PM) concentrations with boundary conditions for CAMS re-analysis is more reasonable than any other data, and the estimation accuracy over the entire Korean peninsula, including the Seoul and Daegu metropolitan areas, was improved. Although an inland area such as the Daegu metropolitan area often has large uncertainty in PM prediction, the level of improvement in the prediction for the Daegu metropolitan area is higher than in the coastal area of the western part of the Korean peninsula.

학습 데이터를 구성하는 각각의 문자들에 대해 서로 다른 글자체들을 픽셀 단위로 더해서 MASK를 만들고, 해당 MASK에 속하는 픽셀값들을 세 영역으로 나눈다. 실험 데이터를 골격 형태로 수정하고, 지역 경계 연산을 사용하여 수정된 실험 데이터의 배경 중에서 문자의 골격에 인접한 배경 영역을 구분하는 경계를 만든다. 수정된 실험 데이터와 MASK들 간의 불일치 정도를 계산해서 최소값을 가지는 MASK를 찾는다. 이 MASK가 해당 실험 데이터에 대해 최종적으로 인식된 학습 데이터 문자로 선택된다. 문자의 골격과 지역 경계 연산을 사용하는 인식법은 주어진 학습 데이터에 새로운 글자체를 추가해서 학습 데이터를 쉽게 확장할 수 있으며, 구현하기가 간단하면서도 높은 문자 인식률을 얻을 수 있다.

If a system such as a port and regional economy has a large boundary and complexity, the system's substance is considered as a black box, forecast accuracy will be very low. Futhermore various components in a port and regional economy exert significant influence on each other. To copy with these problem the form of structure models were introduced by using SD model. This study has the issue of simplifying the regional economic effects of the port as contributing to raising the regional income. The regional economic effects of port have various indirect ones except for this. So, SD(System Dynamics) was presented, and applied to simulate port and regional economy.
