This paper investigates the relationship between the oil price and the major petroleum products prices at the trading hubs such as Singapore, North West Europe and the US New York Harbor. We focus on the lead-lag relationship between the weekly petroleum prices from 2009 to 2016 based on the vector error correction model. We find that the oil price leads the prices of petroleum products in the long term, while there is bidirectional causality in the short term. On the other hand, prices of petroleum products in regions with high import dependency, such as Europe gas oil and jet fuel price, are exogenous in the long term. We also present evidence that prices of petroleum products in region with a large global-market share lead prices in other regions. However, if the region is in an over-production situation and low industry concentration, it may lose its price leadership due to intense competition. The result in this study can provide a useful information to petroleum refining companies in forecasting fluctuations of product price, and hence in planning their regional arbitrage trading activities.

The main purpose of this paper is to explore the relationship between the transformation of Chinese regional development policy and trends in spatial inequality in mainland China. More specifically, it has attempted to identify the effects of Chinese regional development policies on regional economic inequality by investigating the coefficient of variation and Gini coefficient with GRDP in the province level. Regional inequality in China had increased from 1979 economic reform, but has eased since the 10th Five Year Plan(2001~2005) due to large-scale state investments in the western, central and northeastern regions. However, the analysis is likely to be resulted from the national level. Trends in regional inequality are differentiated in accordance with the eastern, central, northeastern and western regions. For example, regional inequality in the central region has increased, whereas other three regions has decreased since the 10th Five Year Plan. It has played a role in cutting down regional inequality in the national level. In particular, the central region has kept inequality since the 12th Five Year Guideline. It has led to the convergence of the regional economies in the national level. It has stemmed from some limits to greater regional policies in the Central region enforced in the 11th Five Year Guideline(2005~2010).

In order to assure universal information access right, the present regional gap of public library infrastructure needs to be examined in Korea. The purpose of this study is to propose an effective government financial support policy to local government to bridge the regional gaps among 16 Korean wide autonomous communities. For that purpose, this study analyzed some of the per library and per capita measures, surface areas, number of librarians, number of books, total budgets and budgets for materials, etc, available in the National Library Statistics System. Then, this study reviewed changes and problems in new government financial support systems which started from 2010. Based on the results, a reformation plan of the current government financial system to national subsidy program was proposed.

Television viewing affects viewers' attitudes and opinions on their political issues. Since the beginning of General Programming TV services in 2011, they are criticized of their politically biased programming. In order to investigate the effect of General Programming TV on voters' behavior, we analyzed whether or not there is a change in the voting behavior of the conservative parties among the areas with high and low TV ratings of general programming TV. Based on the result of 18th presidential election in December 2012, we could not find any difference in voting behavior on the Saenuri party among the areas with high and low ratings of general programming TV channels. However, in the 6th provincial election in June 2014, while the voting shares of the Saenuri party were higher in the areas with high ratings of TV Chosun, Channel A, and JTBC than in those areas with low ratings.

This study analyzed passenger access and egress travel patterns related to a Korean regional railway station (Seoul station), then developed a binomial logit model. This model referred to bus and metro mode of access and egress during a national holiday (Chuseok 2009); obtained from transit smart card data. The results showed that 99% of passengers getting access to, or egress from, the regional railway station did so using less than two transfers, and that most passengers were more likely to choose a metro. However, the passengers that made access or egress trips near Seoul Station were more likely to take a bus. From the results of the mode choice model, it was found that the impact of travel time was greater than that of travel cost, in the choices made for both access and egress. Interestingly, the impact of travel time is much greater in choosing the mode of egress.

University has various resources such as intellectual human resource, spatial resource and facilities, and economic resource. At the same time, universities are, in general, found upon fundamental mission of public service, as well as teaching and research. Recently in Korea, it has been argued that we should make use of such resource of universities in the process of urban regeneration through university-community partnership. Yet, these arguments are lack of concreteness: 'which' kind of resource for 'what' kind of problem, and 'how'. Therefore, this research examined the case of university-community partnership in Japan and tried to find of some implications to Korean society. The reason for examining Japanese case is because Japan has experienced similar problems that Korea face such as aging population, decrease in the number of student, deteriorations of existing urban area; there are respectable amount of similarities between Japan and Korea in political, social and economic context; and because Japan has proceeded regeneration of communities through university-community partnerships.

Five microsatellite DNA markers were used to investigate genetic diversity and population structure of olive flounder Paralichthys olivaceus collected from four locations (YD, SC, GJ, WD) where hatchery-based seeds of the flounder have been released. The average of observed (Ho) and expected heterozygosity (He) ranged from 0.833 to 0.871, and from 0.842 to 0.876, respectively. The average number of alleles per locus ranged from 12.4 to 17.8. The proportion of stocked flounder ranged from 20.0% to 95.8% for wild-caught populations with a decreasing tendency of alleles per locus following a higher proportion of stocked flounder. There is need to implement a more careful stock-enhancement program of hatchery-based seeds and to monitor its genetic effects on wild populations to ensure conservation of natural flounder resources.

This study investigated sense of community influencing satisfaction with center teacher and service use evaluation and mediating effects of school adjustment involving sense of community, satisfaction with center teacher and service use evaluation among adolescents in community child center. Secondary data analysis from the 2nd Panel Survey on Service Satisfaction with Community Child Center was performed using data of 438 the first grade middle school aged student in 2017. Correlation coefficient and step-wise Regression using SPSS 18 program 18.0. and Sobel test showed that the higher of satisfaction with center teacher and center service use evaluation influenced the more enhanced sense of community, and school adjustment had partial mediating effect among them. Therefore, to promote low income adolescents' sense of community, this study suggested the need to persist the sustainable relationship between satisfaction with center teacher and adolescents and to improve quality of service and to develop and apply the community action program connecting community child care center and school system.

This study was conducted to identify research trends on the integrated community care system in Korea and suggest future research directions. The scoping review method was conducted according to the JBI methodological guidelines. A literature search was conducted in 5 databases (RISS, DBpia, NDSL, KISS, NAL), and 34 papers were selected for the final analysis. The analysis was categorized into user and provider aspects related to community care, and the results from the user aspect showed that variables related to service satisfaction and physical health status were used the most and showed positive results. Provider aspect results mainly studied problems and improvements due to service provision, and many studies showed the need to revitalize inter-agency collaboration systems and the lack of manpower to perform services. Based on the results of this study, in the future expansion of the integrated community care system, it will be necessary to not only establish criteria for selecting subjects, but also secure the expertise of service providers, establish a collaboration system between regions and institutions, and prepare measures to resolve service differences.

This study aims to analyze the relationship between transport infrastructure investment and rural development in Korea in a more systematic and empirical way. To do so, we formulate research framework to examine the multi-faceted relationship through extensive literature review and carry out a descriptive study on the spatial patterns of road investment and rural development in Korea. Finally, using the structural equation model, this study carries out the exploratory empirical analysis on the direct and indirect relationship between transport infrastructure investment and rural development. The study finds that the transport infrastructure investment in rural Korea impacts clearly on both the population base promotion and production and income growth through better accessibility. In addition, the investment has an indirect effects on the production and income growth through its influence on the population base promotion. This implies that the transport infrastructure investment in rural Korea so far exerts both long-term and short-term influences on rural development through various channels of impacts.
