This study tried to categorize the types of mountain-village areas in terms of some key variables representing the socio-economic and natural characteristics in order to provide basic information for policy formation of mountain areas. Cross-sectional data of the year 1990 for 900 sub-counties were collected to analyse the characteristics of mountain-village areas. Eleven variables were selected to classify the types of sub-county levels. According to the results of the study, the socio-economic conditions of mountain-village areas represented by the number of corporations, number of non-farming households, and population density of mountain-village areas were found to be inferior to other parts of the nation while the proportion of forest land, share of non-paddy crop fields, distance from cities, percentage of farming households, and elevation from the sea-level were higher to the other areas. By the principal factor analysis, the key variables representing industrial development, mountain-ousness, and accessibility from near cities were selected. By a cluster analysis employing the selected variables, 5 different types of mountain-village areas were categorized.

This study investigated development method of governance of local residence, central and local government based on fishing ports as a new paradigm for restoration of sustainable space environment on Hyeonpo Harbor in Ulleung Island. According to the result of conducting a questionnaire survey on residents of Ulleung Island in order to carry out the research purposes, vulnerable living environment as poor accessibility and lack of hospital, community health center, and shopping district were pointed out as the biggest problem of residential environment in Ulleung Island of today. Secondly, there was a high recognition that development project on Ulleung Island of the government and local government is not actually contributing to the revitalization of regional economy and improvement in quality of life of Ulleung Island residents, and thirdly, lack of understanding on the importance or usage of various resources in Ulleung Island and insufficient support of the central government and local autonomous entity were pointed out as the bottleneck factors in implementation of the Ulleung Island development project. Fourthly, they perceived the current management level of Hyeonpo Harbor to be unsatisfactory. The results of this study demonstrated the importance of durability of development entities, vision of development of Hyeonpo Harbor, effort for the change of ownership mind, phased implementation considering reality of the area, and development that can provide small-scale profitable contents than a large theme.

Cities in Korea have rapidly urbanized and they are not well prepared for natural disasters which have been increased by climate change. In particular, they often struggle with urban flooding. Recently, green infrastructure has been emphasized as a critical strategy for flood mitigation in developed countries due to its capability to infiltrate water into the ground, provide the ability to absorb and store rainfall, and contribute to mitigating floods. However, in Korea, green infrastructure planning only focuses on esthetic functions or accessibility, and does not think how other functions such as flood mitigation, can be effectively realized. Based on this, we address this critical gap by suggesting the new green infrastructure planning framework for improving urban water cycle and maximizing flood mitigation capacity. This framework includes flood vulnerability assessment for identifying flood risk area and deciding suitable locations for green infrastructure. We propose the use of the combination of frequency ratio model and GIS for flood vulnerability assessment. The framework also includes the selection process of green infrastructure practices under local conditions such as geography, flood experience and finance. Finally, we applied this planning framework to the case study area, namely YeonJe-gu an Nam-gu in Busan. We expect this framework will be incorporated into green infrastructure spatial planning to provide effective decision making process regarding location and design of green infrastructure.

The PRT(Personal Rapid Transit) in material or immaterial guided tracks is operated automatically according to the needs of passengers with the optimal non-stop path from the source to the destination. In recent years, the personal rapid transit (PRT) system, which affords superior accessibility and ease of use, has been spotlighted as a new transport system for the future. In this study, a method for vertical lifting of PRT vehicles was proposed to facilitate interlink with other means of transport and thereby improve the efficiency of door-to-door transport. For this purpose, operation control interfaces were designed and experiments were conducted. Programmable Logic Controller (PLC) dedicated for the PRT vertical lift was designed to interface with Operation Control Center (OCC) by Modbus TCP over Ethernet. We implemented a 3D graphical PRT operation simulator which can emulate the mixing operation of the virtual vehicles and the actual vehicles.

Objectives: This study compared the welfare level and leisure activities of children and the youth in urban areas with rural areas, and examined factors affecting their life satisfaction. Methods: The fourth wave of the Youth Panel data collected by the Korea Youth Policy Institute has been utilized. A total of 3,145 sample was drawn, and the average age of the sample was about 17 years old (a sophomore in high-school). T-test and multiple regression has been employed. Results: In almost all welfare related variables including life satisfaction, leisure satisfaction, parent attachment, and relationship with teachers and peers, the rural children and youth showed lower scores than their urban counterparts. The only factor whose score was higher to the rural children and youth was community factor including community attachment and guidance. In terms of leisure (satisfaction) level which was the most influential factor of predicting the variance of life satisfaction, the rural children and youth revealed unfavorable condition, as their accessibility to the facilities was low and there were less facilities in rural areas in the first place. Conclusions: As a way to improve the welfare and cultural level of rural children and youth, this study proposed to make investment to the rural areas by providing them with welfare and leisure infra structure and various welfare and leisure programs. To improve the outdoor leisure activities of the urban children and youth, setting up a sisterhood between urban and rural schools has been suggested.

In Korea, playgrounds have been developed quantitatively and qualitatively. However, there is a lack of interest in the play needs of children with disabilities. With this in mind, this study is concerned about the planning and design process of the inclusive playground constructed in 2016 at Seoul Children's Grand Park. The case study covered the Kkumtle Kkumtle playground in Seoul Children's Grand Park and was completed in December 2015. This playground is the first case of an inclusive playground ever built in Korea. The concept of the inclusive playground established in this study is: (1) a playground where not only children with disabilities but both children with disabilities and children without disabilities can play together; (2) a playground for both children with disabilities accompanied by their families and children without disabilities accompanied by family members with disabilities; (3) a playground that ensures universal accessibility to the entire space including play facilities; and (4) a playground where the most essential functions of a playground-fun, curiosity, and adventure-are centered on various activities. In conclusion, we presented limitations and opinions for improvements to design and policy proposals for social expansion of inclusive playgrounds. There are three ways to overcome limitations in design. First, there is a need for an in-depth study of play characteristics by type of disabilities of children. Second, it is necessary to develop facilities suitable for the actual situation of Korea through various social experiments. Third, if the inclusive playground centered on facilities is presented in this study, then several types of integrated playgrounds should be implemented in the future.

For efficient development of rural facilities, choice of their optimum locations would be an important issue, however, existing research works concentrated much more an allocation policy of urban industrial complex and public facilities than rural ones. In this study, because agricultural-cum-industrial complex has been the most widely developed representative one of rural facilities, it was selected as a case study facility. As a pre-study to system development, existing governmental location-decision system was checked and interviewing survey carried out to find out on-spot problems. And, being based on literature review and survey analysis results, 4-step optimum locational decision model was developed , formulation of locational goal system, ranking tabulation on components, determination of significance values of components, calculation of component scores. Finally, through the case study works on 3 sites, system applicability was checked, Considering together the simplicity problem of existing guidelines and the interviewing survey results favoring the diversified viewpoints, it would be necessary to develop multifaceted support system for locational decision making. 3-tier classification steps from the higher, middle to lower one were used and their underpinning viewpoints were sorted as on regional development, entrepreneurship, spatial rationality, from which a tentative locational goal system was formulated. Through the expert group checking, final locational goal system was determined having 3 of the higher classification items, 7 of the middle ones, 23 of the lower ogles. For ranking tabulation, 3 types of ranking criteria were arranged which were based on statistical analysis using mean and standard deviation(Type I ), its existence or not 1 good or not(Type E ), and the others(Type E ). From the significance evaluation results, regional development and entrepreneurship aspects were valued much higher than spatial rationality aspect. And, in the middle step, items as spread effects of regional economy, accessibility and social potentialities were highly valued while infrastructural development level and natural condition being low. The application results of the system to 3 case study total. However, the detailed ones differed among study the influencing effects on regional economy, and contrast greater the infrastructural development level. Conclusively, final evaluation values well represented the characteristics of each area. If this system be complemented and applied comprehensively by the successive studies, it would be developed to a general model of locational decision supporting system for rural facilities.

The purpose of this study was to examine any possible differences among adolescents in unmet dental care needs according to their demographic and socioeconomic characteristics and oral health status and influential factors on the basis of the fifth national health and nutrition examination survey data. The findings of the study were as follows: Unmet dental care needs were accounted for 19.84 percent. As for the reason, many replied that they couldn't afford to leave school during school hours, and economic factors. As a result of analyzing what affected their unmet dental care needs, this experience was more common in the older age groups than in the 6~12 years age group, and the experience was less common in the respondents with a larger income. As for the subjective oral health status, the experience was 0.61-fold and 0.72-fold less in the respondents who perceived their health as fair or good than who thought their health was poor respectively. And there was a tendency that getting regular dental checkups led to 0.22-fold less experience. Given the above-mentioned findings, the kind of policy that makes dental care services more accessible to youth in consideration of socioeconomic circumstances should be carried out. As many of the adolescents couldn't leave school during school hours, schools should be equipped with dental clinics to improve accessibility to dental care services.

This paper first extracts the main basis for the Middle-Income Trap(MIT) to apply these grounds to reality of the Chinese economy. And then confirmed crisis factors of China economy. Also discussed then the economic reforms of China in order to not fall into the MIT. After reviewing previous research extracted six factors the results will correspond to comply with the Chinese economy. Those are 'Over-investment', 'excess capacity' 'reduction of TFP continued,' 'disappearance and the aging of the population bonus', 'excessive debt and structural adjustment and financial instability of the company', 'income unequal expansion', 'low financial and information infrastructure accessibility', and 'low transparency index'. China's policy direction to avoid the MIT generally set properly, but proof that implementation process not easy, was appearing everywhere. After all, China economy should be modified now to a reforms of 'government failure' and promotion of function for ongoing restructuring system in the market. Because of the SDR incorporation from 2015, it is inevitable to face major constraints in the external aspects.

The study aimed to analyze the structure of China's passenger railway network in the years of 2008, 2013, and 2018, respectively. At the same time, it tried to investigate its derivative impact on the patterns of Chinese urban network. The analytical tool was based on the NetMiner4.0. In order to measure network characteristics of China's passenger railway network, it primarily focused on the degree centrality, betweenness centrality, and closeness centrality. First of all, the higher degree centralities, with a few exceptions, were observed in BeiJing, ShangHai, GuangZhou, WuHan, XiAn, ChengDu, HaErBin, and ShenYang over a decade. In contrast, the higher betweenness centralities were recorded in cities of higher development potential including WuLuMuQi, GuiYang, ShenYang, and KunMing. The closeness centrality analyses confirmed the fact that most metropoles like BeiJing, ShangHai, and GuangZhou kept the highest train accessibility during the same research period. At the same time, the opening up of a new stretch of high speed railway network has consecutively strengthened connectivity between BeiJing and TianJin. Owing to unprecedented development of railway traffic and its extensive operations, this study believes that Chinese major cities, without interruption, would pursue a series of urban policy alternatives geared towards railway stations-oriented networking and competitively try to extend their network ranges.
