This paper attempts to evaluate the local economy and the local economic development policy in Goryeong County and to propose some policy alternatives for local economic development. Goryeong County has a locational advantage, which is not just geographically proximate to Daegu, a large metropolis, but also connected directly to the national highway networks. This region can also be regarded as a rural area, in a sense that the primary industry still plays a more important role for the local economy than the secondary industry and the tertiary industry. However, it is problematic that the local economic development strategies of Goryeong are universal rather than strategic and systematic. In order to design an effective regional economic development policy, the policy makers are necessary to deliberately consider regional specificity and geo-political and geo-economic situations around the region. In addition, it is important to say that policy makers, particularly in rural regions, need to break from the fantasy of high-tech industries. In this context, I propose some region-specific and context-specific policy ideas, including the promotion of the agro-food cluster and the build-up of the em-industrial complexes specialized in mechatronics and transportation equipment manufacturing.

The urban-rural consolidated city has emerged in order to promote the balanced development of urban region and rural region. Targeted 11 urban-rural consolidated cities in Gyeonggi Province, this paper investigated the changes of economic space in accordance with the location of industrial activities. The number of establishments has increased in all cities. From the analysis of the changes in the economic space divided into urban regions and rural regions, concentration phenomenon of economic activities in urban regions was strengthened in 9 cities with the exception of Icheon-si and Anseong-si. Concentration of economic activities in urban region was noticeable in Namyangju-si, Pocheon-si, and Yongin-si. 5 types were derived from the classification on the basis of locational changes of economic activities in urban region and rural region. They are 1) urban-rural gap deepen type, 2) urban region growth slowdown type, 3) rural region growth type, 4) urban-rural balanced growth type, and 5) urban region-led growth type. While urban-rural gap of the cities close to highly urbanized city or metropolis has intensified, the growth of urban region was weakened in the cities located away from the metropolis.

Mt. Bonghwa reaches a height of 800 m (2,870 ft) and stands on the flank of Mt. Daeam-san, which has an elevation of 1,304 m (4,278 ft). It is important to survey the flora of Bonghwa-san in that it is a way to make out what kind of plant species exist in DMZ due to the geographical characteristics of Bonghwa-san adjacent to Korean DMZ. Therefore this study was conducted to elucidate the distribution of vascular plants and their value of Bonghwa-san. The vascular plants that were collected 10 times from May 2015 to April 2017 consisted of a total of 525 taxa; 93 families, 309genera, 458 species, 4 subspecies, 58 varieties and 5 forms. The observed rare plant species as designated by Korea Forest Service were 12 taxa including Echinosophora koreensis, Epimedium koreanum, Anemone koraiensis etc. Endemic species were 16 taxa containing Cirsium setidens, Heloniopsis koreana, Salvia chanryoenica etc. 31 taxa were recorded as naturalized plants and their naturalized rate and urban index were noted as 5.8% and 7.25%. Among the surveyed 525 taxa, edible, medicinal, pasturing, ornamental, timber, dye, fiber and industrial plants included 213 taxa, 172 taxa, 196 taxa, 50 taxa, 23 taxa, 10 taxa, 6 taxa and 3 taxa, respectively.

DMSP-OLS nighttime satellite imagery could be used to derive the sum of lights (SOL) and built-up area, and the two indices have been widely employed to make the estimation of socio-economic variables and the dynamics of urban developments. Considering it, this research investigated the spatiotemporal patterns of economic growth and urbanized area in Jilin Province, China, using DMSP-OLS data for a time span between 1992 and 2012. This study found the SOLs of both the province and most cities to tend to grow during the period. While SOL-weighted centroids' means moved towards northwestern direction, urban-area centroids' means followed the trend of south-eastern migration. These directional patterns could be associated with the Northeast Revitalization Plan of Chinese governments. Nonetheless, a future study will need to consider SNPP VIIRS DNB imagery in order to overcome temporal limitation of DMSP-OLS data. In addition, it is also necessary to estimate socio-economic indices, e.g., growth regional domestic product, using a regression model developed with correlation relationship between economic statistics ad SOL.

Estuarine wetland, where freshwater meets saltwater, is a transitional ecosystem that is valuable ecologically for a variety of reasons, such as feeding and breeding sites for birds, fish, and wildlife. However, research on the spatial distribution and temporal dynamics of estuarine wetlands in Korea is rare. As a fundamental basis for wetland conservation, this study quantified the wetlands in three major estuaries, and evaluated the temporal dynamics of the wetlands since the 1910s. In particular, this study classified the wetland types into mud flat, sand, and emergent-plant types, and estimated the change of each wetland type, using topographic maps produced in the 1910s, 1970s, and 2000s. The wetlands in both the Han and Youngsan River estuaries have declined since the 1910s, but the rate of wetland decline was relatively low before the 1970s, compared to that since the 1970s. The impact of human activities, such as the Youngsan Watershed Comprehensive Development Project and the construction of estuary barrages, has disrupted the estuary cycles and destroyed huge amounts of wetland in the Youngsan estuary. By contrast, estuarine wetlands have been preserved in the small Gahwa estuary, and provide a variety of habitats for plants and wildlife. A special management strategy for wetlands should be established as soon as possible.

지속가능 에너지원인 원자력은 또한 글로벌 에너지원의 특성을 갖추고 있다 핵연료는 원자로에 장전되는 신규 핵연료를 구성하고 있는 우라늄 채광 단계에서부터 연소 후에 발생하는 사용후 핵연료 (SNF 또는 SF) 관리 단계에 이르는 전과정에 걸쳐 핵연료 사이클로 파악되고 있다. 이러한 전과정 관점에서 볼 때, 핵연료 사이클에 관여하는 이해관계자는 자국뿐만 아니라 다국가 (multination)를 포함하고 있다. 특히, 후행 핵연료 사이클인 사용후 핵연료의 저장, 처리, 처분 단계에서는 다국가 시나리오를 배제하지 않는 사용후 핵연료 관리 전략의 도입이 고려될 수 있다. 여기서 다국가는 접경 국가, 인접 국가, 핵연료 공급 국가, 재처리 제공 국가, 재처리 위탁 국가, SNF 통과 허용 국가, SNF 저장 부지 제공 국가, SNF 향후 이용 국가 등이 될 수 있다 [김성호 2006]. 현재 우리나라에서는 여러 국가로부터 수입되고 있는 신규 핵연료 물질을 연소시켜 나온 사용후 핵연료를 부지내에 임시 저장하고 있다. 사용후 핵연료 발생량의 추산에 따르면, 2016년쯤에 현재 임시저장 용량이 포화될 예정이다 이러한 상황에서 다국가 시나리오를 포함한 관리 전략은 다국가 시나리오를 배제한 관리 전략과 다각적인 측면 에서 비교 검토될 필요성이 있다. 사용후 핵연료의 영구 처분장 부지 확보를 해결하기 위한 선행 단계로 공론화 단계가 지금 준비되고 있다. 예컨대, 단기 공론화 관리 방안의 하나로 비록 소극적인 입장이지만 타국 위탁 재처리 방식이 고려되고 있다 [KRS 2009] 이 연구에서는 단기적인 사용후 핵연료 관리 전략으로 여러 가지 다국가 수준의 저장, 처리, 처분 방식으로 바탕으로 다국가 시나리오들을 제안하려고 한다. 이들 다국가 시나리오를 포함한 관리 전략은 현재 다국가 시나리오를 배제한 국내 사용후 핵연료 처분장 부지 선정이 정치적/사회적 수용성 문제로 어려운 상황에 처할 경우에 해결책을 찾는 데에 기여하리라 본다. 또한, 부지 선정 단계에서 바라지 않는 난항이 나타나는 경우에 국가 차원의 한 대비책으로 다음을 제안한다: 한편으로는 자국 저장 시설이 추진되면서, 다른 편으로는 타국 저장 부지를 확보하는 전략이 검토되어야 한다. 이러한 이중 노선 (dual track) 전략은 여러 유럽 국가에서 이미 고려되고 있는 방안이다 [Greenpeace 2005] 다양한 다국성 정도 (a degree of multinationality) 의 저장, 처리, 처분 방식을 연결하는 가능한 다국가 시나리오 구조가 Fig.1에 제시되어 있다. 다국가 시나리오를 구성하는 기본 요소는 다음과 같다’ 1) 자국 임시 저장; 2) 자국 재처리; 3) 자국 중간 저장; 4) 자국 영구 처분; 5) 다국가 중간 저장; 6) 다국가 재처리; 7 ) 다국가 영구 처분. 이들 기본 요소들을 다국성 정도에 따라 결합하면 다양한 다국가 시나리오들이 얻어진다. 이들을 포함한 SNF 관리 전략은 크게는 1) 다국가 재처리 전략， 2) 다국가 저장 및 재처리 전략， 또는 3) 다국가 처분 전략 등으로 분류될 수 있다.

There is a limestone basin surrounded by the mountains consisted of Paleozoic sedimentary and metamorphic rocks in the Masung, Munkyung city, Kyungsangpook do. The purpose of this paper is to elucidate the geomorphic processes of the gentle hillslopes in the marginal piedmont of Masung basin. To do so, I analyzed deposits over hillslopes and the relation ship between the distance from the divide and the height(above sea level) at the longitudinal profile of the hillslope, and considered interrelation between the distributions of the gentle hillslopes(less than 230m) and lithology. Geomorphic processes of Masung basin are as follow: (1) The depth of deposits over hillslope increases toward downstream of the hillslope. Most gravels within deposits, whose lithology is limestone, are those eroded at the boundary(overthrust fault zone) between the back-mountain and the hillslope. Deposits at the outward margin of hillslope is well sorted. and moderately imbricated. (2) Hillslope at the margin of the basin(160-230m asl) is formed by the action of 'the flow with channel'. At the boundary between the soft rock(limestone; basin floor) and hard rock(sedimentary and metamorphic rock; back-mountain), the relatively weak limestone is eroded to fresh bedrock by the subsequent action of the overland flow, and therefore discontinuity in slope appeared. (3) After hills lopes were formed, sediments(boulders and fine material) produced during dissection in back-mountain buried deposits over hillslope. In conclusion, geomorphic processes of Masung basin is 'differential erosion due to differentiation of lithological hardness' having suggested as geomorphic processes of granitic basin. However it is not 'removal of weathering material due to sheetflow' but 'erosion due to the overland flow with channel'.

There are increasing needs to provide sufficient information on road directions through road signs for expanding cities and traffic networks. Improving efficiency of direction guidance information from road signs not only requires criteria for but also systematic approach to selecting place names that appear on road signs. As such, this paper looks at road direction information from existing road signs that leads to Suwon and investigates whether the current system of road signs provides efficient, systematic and continuous direction information for road users to easily reach their destination. In this paper, Suwon's city hall is set up as the final destination, which is linked from five other cities, Anyang, Osan, Ansan, Yongin and Seongnam. The paper attempts to find out whether there is continuity and suitable number of road signs for direction information by analyzing the road signs between these 5 cities and Suwon with respect to direction, direction advance notice and direction guidance. It is found that drivers cannot easily find the needed information on their destination from the existing road signs and that continuity of selected place names that systematically appear on road signs is insufficiency. In addition, direction guidance on road signs is problematic, because the appearance frequency of road signs is not adequate and the continuity of road signs is not effective. Moreover, there is insufficient information on local direction guidance for immediate destinations on road signs with respect to turning left or right or going straight.
