This study investigates the spatial characteristics of the provision of and demand for the private tutoring service industries and the consumer groups. For the purpose, we analyze the spatial characteristics of various types of tutoring institutes in the Seoul Metropolitan area. In particular, we exam the spatial distribution patterns of attendants of tutoring institutes by institution type as well as the resident population by attendant age group. By applying spatial autocorrelation analysis, we examine the spatial clustering patterns of tutoring institutes and attendants by type. The results show distinct differences in the spatial distribution patterns by tutoring institute type as well as by attendant age group. We found significant socio-economic variables which influence on the spatial distribution of tutoring institutes. Finally, we propose private tutoring service provision models constructed with these variables through multiple regression analysis.

This paper analyzes the topological structure of housing market networks with an application of minimal spanning tree method into apartment sales markets in the Capital Region over the period 2003.7-2014.3. The characteristics of topological network structure gained from this application to some extent share with those found in equity markets, although there are some differences in their intensities and degrees, involving a hierarchical structure in networks, an existence of communities or modules in networks, a contagious diffusion of log-return rate across nodes over time, an existence of correlation breakdown due to the time-dependent structure of networks and so on. These findings could be partially attributed to the facts that apartments as a quasi-financial asset have been strongly overwhelmed by speculative motives over the period investigated and they can be regarded as a housing commodity with the highest level of liquidity in Korea.

This study aims to investigate the success factors of each market through the case study of Seoul Gwangjang and Jangheung Toyo(saturday) market which have recently developed as tourist attractions among urban and rural traditional markets in Korea. In terms of location, market week, establishment and management of traditional market, Gwangjang is a private and daily market located in the city center of Seoul, and Jangheung Toyo is a public and periodic market located in rural Jeolla Nam-do Province. Nevertheless those differences, two markets have successfully developed as tourist attractions by the complexity of generally common five factors. Those are the factors such as surrounding location of famous tourist attractions, competitive staple goods(items), price competitiveness for goods, roles of local government and(or) public institution, and marketplace promotion through the mass media. These factors will have a significant implication for the development policy from traditional market to tourist market or tourist attraction.

This study aims to analyze knowledge extension and diffusion trend among industries through technological convergence in non-Capital rural areas. A case of Sunchang, Korea examines knowledge extension trend of fermented soy product manufacturing industry. Patent application data are used to make technology convergence analysis and knowledge network analysis. Patent analysis results show that there are differences of knowledge extension trend between the whole country and Sunchang. Technologies of fermented soy product manufacturing in Sunchang is inclined to extend toward technologies related to fermented microorganism. Contrary to the whole country, knowledge extension in rural area like Sunchang is converged to technologies suitable for specialized but limited regional assets and human resources. Core actors of knowledge network of fermented soy product manufacturing in Sunchang are mainly public organizations such as local government, universities, and agencies or institutes. Recently technology sharing and extension is likely to occur through the cooperation between associative corporations and public organizations.

This paper attempts to understand the nature and dynamics of global value chains in the auto industry using the OECD TiVA 2015 edition on the bilateral foreign value added in exports over the period 1995-2011 and employing the techniques of social network analysis such as the computation of network measures and visualization of value added trade flows. It is shown that there has been a tendency towards increasing production fragmentation both within and across regions. The automotive value-added network is found to have small-world properties with a hierarchical, clustered and dense structure. The differences among the US, Germany and China as major suppliers of foreign value added in global automotive value chains are remarkably revealed. Although the fragmentation of production has been developed on a global scale, a dichotomous tension between center and periphery and domestic and foreign capital lies behind it.

This study focuses on the economic effect on regional development and spatial distribution of community festivals and events as a regional development strategy in South Korea. Community festivals are totally estimated to 893 cases in 2009, and most of festivals were newly established since 1995. Spatial Distribution of festivals show regional differences. Many of festivals was hold in Jeju, Gyeongnam, Ulsan, and Chungnam provinces, however, Gyeongbuk, Jeonnam, Gwangju, and Gyeonggi provinces were distributed less. The total number of cultural tourism festivals selected as best festival by central government were increased from 10 in 1997 to 57 in 2009, and the everage local economic effects of one cultural tourism festival were also increased from14.2 billion won in 1997 to 33.3 billion won in 2008. In order to estimate the relationship between community frstivals and local economic effect, Geumsan Insam Festival, Muju Firefly Festival, and Hampyeong Butterfly Festival are selected as case study. These three festivals were successful in the tourist attraction, and it were also affected positively to local economic effect.

This study was performed to suggest the basic data and plans for the establishment of safe water supply plans in simple water supply piped system in the rural areas. In 4 different places, 24 points of water sources 36 points of taps from water sources were sampled. Of the whole 60 points, 55 points were ground water and 5 points were surface water. 14 items were measured for the analysis of water quality on each samples. The measured items were analyzed again by statistical method ; cluster analysis and principle components analysis. The results of this study are as followed. 1) In water quality analysis on water sources, 4 items, bacteria, E.coli, NH3-N and Fe exceed the standard. Of 24 points, 20 points(83%) on bacteria, 1 point(4%) on NH3-N and Fe exceed the standard. 2) In water quality analysis on near and remote taps, 4 items, bacteria, E.coli, NH3-N and Fe , exceed the standard. Of 36 points, 20 points (81%) on bactria, 1 pint(3%) on NH3-N and Fe exceed the standard. 3)Cluster analysis on water quality shows the differences by the kinds of water sources, geographical characteristics and distance from water sources. 4) Principle components analysis on ground water shows that Factor 1 and Factor 3 are natural fluctuation by the content of soil. Also, Factor 2 and Factor 4 are penetration of pollutants to underground. Therefore, it is needed to take deeper ground water in order to prevent from pollution in the areas which have ground water as water source . 5) Principle components analysis on surface water shows that Factor 1 is penetration of vacteria from surface to water source when rainfalls. Also, Factor 2 is fluctuation of water quality by the geographical characteristics. Therefore, the counterplans against non-point pollution source must be taken. Filtration and disinfection facilities are needed in the areas which have surface water as water source.

The importance of R & D activities has been emphasized in modem economy due to rapid growth of high-tech industry. This research has taken a macroscopic approach to understand the spatial location pattern of company-affiliated R & D institute. According to the result based on this analysis, a number of company-affiliated R & D institutes have shown high centralization in Seoul Metropolitan Area(SMA); however, more serious analysis has shown that institutes have different regional tendencies based on their industrial classifications with lower high-tech tendencies show less centralization in the SMA. Moreover, it also has indicated that larger corporations or higher capability of hiring top class researcher have tendency to decentralize their institutes. The result also points out that institutes are likely to be located near their head offices or factories; or located along with other research institutes in the same industrial field. The locations of the institutes, however, have shown the regional differences as well. After taking all the characteristics into consideration, this study has categorized types of institutes locations into four groups.

This paper is to explore the cross-border interactions and the formation of trans-boundary regional identity in the Swiss-German-French border region. It begins with a brief review of recent studies on 'boundary and border region', in order to gain a insight into the theoretical debates on this theme and to find out ideal types of the cross-border co-operations. And then it deals with the everyday cross-border movements(working, shopping, living) in 'Regio TriRhena', discussing the development of the trans-boundary co-operations in the EuroRegion 'Upper Rhine'. There are several committees to be defined in trans-boundary co-operation on the 'Upper Rhine', with different scopes of action, structured collectively like Russian dolls(Babushka principle). The economic differences between 3 countries trigger massive cross-border movements. This paper attempts to organize these cross-border interactions around Ullman's 3 bases for spatial interaction(complementarity, transferability, intervening opportunity). In conclusion, this paper shows that the elimination of economic obstacles does not suffice to create trans-boundary identity or a trans-border common regional spirit.

Housing market is segmented through 1) housing supply classified by housing characteristics and 2) housing demand classified by different housing opportunity of household. Moreover, neighborhood plays a role in intensifying housing market segmentation as a factor affecting on decision making relevant to housing supply and demand. while segmented housing markets have different mechanism, existing studies on residential differentiation and housing market have overlooked the characteristic differences among housing submarkets as the studies presume metropolitan housing market to be a single housing market. while the concept of 'residential differentiation' pays much attention on spatial pattern after the ecological approach appeared, the concept of ‘housing submarkets' is explanatory of the process of urban space structure formation. Analysis on housing submarkets makes up for the weak points of the behavioral approach inquiring into socio-economic constraint and different housing opportunity of household.
