레이저 프로파일링 시스템의 등장으로, 기존에는 얻을 수 없었던 도시 지역에 대한 DTM 취득이 가능해졌고, 더욱 정확한 정사투영영상 또한 제작할 수 있게 되었다. 하지만, 높이 변화를 보이는 자연지물과 인공구조물이 있는 지역에 대해 기존의 정사투영사진 제작기법이 적용될 때, 폐색이나 이중매핑과 같은 문제가 발생하게 된다. 특히 고층건물이 밀집되어 있는 도심지에서 이러한 현상은 두드러져 정사투영영상의 품질을 저해하는 주요한 원인이 된다. 따라서, 본 연구에서는 카메라의 외부표정요소와 DTM을 이용하여 폐색영역을 탐지하고, 폐색이 안된 다른 영상의 정보를 통해 폐색영역을 복원하여 더욱 완전한 정사투영을 제작할 수 있는 알고리즘을 제안하였다. 제안된 알고리즘에 의해 자연지물이나 인공고조물에 의한 폐색영역을 탐지할 수 있었고 폐색영역의 많은 부분을 부가영상을 이용하여 복원하였다. 건물에 대한 사전지식을 이용하여 폐색영역을 탐지하는 국내 연구가 있지만, 본 연구는 건물에 대한 부가정보나 모델링을 사용하지 않고 DTM과 카메라 외부표정요소만을 이용하여 폐색영역을 탐지한다는 점에서 이러한 연구들과 차별성을 가진다.

우리나라의 현행 수질오염총량제도에서 비점오염원에 대한 배출량은 배출원별로 유량조건에 따라 배출계수를 적용하여 산정하고 있으나, 강우 및 유역특성에 따라 크게 좌우되는 비점오염 배출특성을 반영하는 것에는 어려움이 있다. 한편, 역산모델링은 결과를 바탕으로 원인 값을 추정하는 방식으로 유량 및 수질측정결과, 점오염원 배출량 등 실측결과를 바탕으로 비점오염 배출량을 추정할 수 있다. 본 연구에서는 역산 모델링 기법을 이용하여 경안천 유역에서 배출되는 총인의 비점오염 배출량을 추정하고, 부하지속곡선을 통해 비점배출기준을 산정하고자 한다. 경안천 유역의 수질 및 유량측정자료, 하수처리장 현황, 오염원 자료 등을 수집하여, 점오염원 배출량을 추정하고 역산 모델링을 수행하였으며, 비점배출총량을 산정하였다. 본 연구의 결과는 현행 수질오염 총량제도의 배출계수에 대한 재검토와 향후 유량조건에 따른 차별적인 비점오염원 관리 필요성에 대한 기초자료로 활용될 수 있을 것으로 사료된다.

The economic reform in China since 1978 has been increasingly sped up and deepened. The recent development of private enterprises, especially, has significant economic and political implications, whereas its regional differentiation has considerable impacts on both the development potential of certain regions and overall regional growth pattern. This study aims to understand the regional pattern of private enterprise growth as well as the institutional change which has structured the growth process. The development of private enterprises turned out to be closely tied to the marketization strategy of dual-track system and policy needs to reduce the unemployment level in both urban and 겨ral China. The regional pattern of the private enterprise growth can be characterized as ever-increasing spatial differentiation. Based on the basic statistical analysis results, it is argued that the private enterprise growth is closed related with the marketization level of the regional economy. Therefore, the strategy of developing private sector will be more important in shaping the regional development path as well as potential.

This study investigates the occupational mobility patterns of young wage employees at the local level of the labor market and empirically examines the interplay between worker-level and local labor market-level determinants between 2010 and 2020. The 4th to 14th waves of the Youth Panel 2007 were integrated with the Korea Network for Occupations and Workers and the Local Area Labor Force Survey for estimation using hierarchical linear model. Our results indicate that Gross Regional Domestic Product per capita is key determinant of occupational upward mobility. Also, Estimates of employment size, population density, and the unemployment rate of local labor market have different effects depending on the education level and occupational location of youth workers, suggesting that the effects of structural factors of local labor market may not be distributed equally among all youth wage workers. The findings have policy implications regarding the recent rise in inequality and polarization in local labor markets.

Chungchong-namdo area is place that Baekje cultures are straggling. Many ruinses of grant exist and is having special quality of seeing area such as Muryeongwangreung, Busosanseong, Gongsansung as Baekje cultural areas' center with Kongju of Buyeo. More than goods that equip the area's color if see culture goods been selling in tourist resort that there are many resemblant goods that can see in any local and goods development is insufficient misgovernment. Tourists understand history of the area and culture through head relic of having wide knowledge official rank and master basic knowledge. This research proposes culture goods design that apply relic that is excavated in Baekje culture station as a way to based Chungchong-namdo area culture and keep another province station and discrimination. Meantime, interest about Baekje histories was lacking but interest about Baekje histories is decaying through movie or history drama etc. the latest. Hereupon, Chungchong-namdo area culture expects to be activated developing goods design that combine traditional culture and modem thing accomplishes with beauty appropriateness and formative.

This article aims to overview the present condition of the film festival, as one of the cultural policies for regional development, and draw up a plan for them, focused on PIFF and JIFF. Pusan and Jeonju have their own movie infrastructure and each festivals has a distinction as to property and purpose. But, for the festivals to be successful continuously, more regionally suitable and unique events are needed. In case of PIFF, it is required that the promoter should highlight regional characteristics of Pusan, by dint of implementation of programs, centered on people's active participation in the festival; regarding JIFF, for Jeonju to be a mecca of media industry, long-term plans and policies are to be made. The plans for revitalization of International film festival, as local cultural festival, are as follows; good use of local place as movie location, development of relevant contents, formation of regional networking, and cultivation of local human resource.

This paper attempts to explore the relation between health care availability and child mortality among ethnic groups with different cultural traditions of sex preference. Micro-data from the 1990 Census of China for Yanbian and Xishuangbanna Prefectures are used. Based on the analysis of data for Koreans, Hans, and Dais in these prefectures, a new model explaining the relation between sex preference, health care. and differentials in child mortality is proposed in this paper. In societies, where health care is easily available, the level of child mortality is not likely to be a function of sex preference. In societies where there is little availability of health care, members of ethnic groups with strong sex preference do whatever possible to assure survival of their children of the preferred sex. But actions to assure survival of children of the sex not preferred by their parents depend on the costs involved and other considerations. Therefore, the level of child mortality for the preferred sex is likely to be substantially lower than that of the not-preferred sex. However, as availability of health care improves and the cost of obtaining health care becomes lower, survival of children of the not-preferred sex are likely to improve. It is generally agreed that Koreans and Hans show strong son preference, while Dais have cultural traditions of daughter preference. In Yanbian, where virtually all children receive health care whenever it is needed, Korean females and Han females show lower child mortality than their male counterparts, although the difference is not found to be significant for Koreans. In Xishuangbanna, where there is little availability of health care, Dai males show markedly higher child mortality than Dai females, and Han females have higher child mortality than Han males. However, small improvements in the availability of health care in Xishuangbanna translate into substantial improvements in survival of male children for Dais, and survival of female children for Hans.

The purpose of the study was to conduct an empirical study on the scope and level of social exclusion experienced by persons with psychosocial disabilities. The Wave 6 data of the Panel Survey of Employment for the Disabled were used to investigate the current status of social exclusion in life areas including income, education, work, housing, health, social network, social participation, and discrimination (N=4,161). A series of logistic regressions were executed, with the psychosocial disability(PD) group being the reference; the reverse odds rations of different disability groups were compared against the PD reference group (OR=1). The results showed that compared with all others, the PD group was about 2 to 11 times more likely to have risks in income, work, and housing; and that compared to other groups except for the autism/developmental disability group, they were about 6 to 10 times more likely to have risks in social network, social participation and discrimination. In conclusion, the authors urged the need for legal mandates to have community based mental health services and welfare services for the disabled more available to the PD groups and the necessity to eliminate various discriminatory legislations that are violating human and social rights of the persons with PDs.

This study conducted an empirical analysis of how different types of living retail businesses affected housing prices during the COVID-19 pandemic, with a particular focus on both global and local time series effects. The main findings are three folds: First, from a global perspective, the study discovered that the presence of living retail businesses had a significant impact on prices of nearby apartment, varying according to their type. Secondly, the impact of COVID-19 on the retail industry varied depending on the type of business. Thirdly, when viewed from a local standpoint, the impact of the retail business sector on apartment prices due to COVID-19 pandemic was substantial, varying across regions and business types. This implies that external shocks like COVID-19 have the potential to alter the role and perception of living retail businesses. In light of this, the study has put forth policy implications aimed at mitigating the adverse effects of living retail businesses and enhancing residential quality.
