Most of earthquake-induced geotechnical hazards have been caused by the site effects relating to the amplification of ground motion, which are strongly influenced by the local geologic conditions such as soil thickness or bedrock depth and soil stiffness. In this study, an integrated GIS-based information system for geotechnical data, called geotechnical information system (GTIS), was constructed to establish a regional counterplan against earthquake-induced hazards at an urban area, Daejeon, which is represented as a hub of research and development in Korea. To build the GTIS for the area of interesting, pre-existing geotechnical data collections were performed across the extended area including the study area and a walk-over site survey was additionally carried out to acquire surface geo-knowledge data. For practical application of the GTIS used to estimate the site effects at the area of interesting, seismic microzoning map of the characteristic site period was created and presented as regional synthetic strategy for earthquake-induced hazards prediction. In addition, seismic zonation for site classification according to the spatial distribution of the site period was also performed to determine the site amplification coefficients for seismic design and seismic performance evaluation at any site in the study area. Based on the case study on seismic zonations at Daejeon, it was verified that the GIS-based GTIS was very useful for the regional prediction of seismic hazards and also the decision support for seismic hazard mitigation.

In the era of diversity and creativity, autonomous regional regeneration is being emphasized. Local regeneration effects through local heritage utilization and the value of regional properties are rising. It is very meaningful to find a way to revitalize the urban regeneration system that can transform the facilities, spaces and industries in underdeveloped regions into opportune properties. This study explores the possibility of self-sustaining development by establishing an endogenous self-reliance system through the localization of industrial heritage. Competitive advantage strategies of regional properties are more important than regional comparative advantages. In the future, more attention should be paid to the intangible value of the city. A genuine city revival should be created as a place with cultural identity through artistic ecology, tradition, community, and aesthetics centering on people.

The purpose of this study is to analyze the process of vertical fragmentation of regional industries in Korea using Revealed Comparative Advantage index (RCA) and Average Propagation Length (APL). First of all, the competitiveness in regional export and substitution of regional imports were strong in the Electricity, Gas, and Water supply sector in Gyeongnam, and consumer-oriented Manufacturing sector in Incheon, Gyeongnam, and Gwangju. The high values of the APL were also found in the regions with common similarity with respect to the industrial structure and the sectors with indirect effects. In addition, the industrial sectors with high quality of infrastructure, and endowed services tended to be located in the beginning of the production chain. FInally, since manufacturing and service sectors in Seoul has higher APL, they could lead the growth of other related industries as key sectors, in the production fragmentation.

In 2005, the selection of 10 innovation cities was completed, and since 2013, public institutions began relocating to innovation cities. As a policy aimed at promoting balanced regional development, there were significant expectations from the regions. However, although the population moving to innovation cities has increased, it remains to be seen how much inflow is from the capital region and what spatial characteristics exist nationwide. Therefore, this study aims to analyze whether the innovation cities are fulfilling their roles by examining the patterns of inflow from the capital region and the spatial characteristics, and to reassess the policy direction for future innovation cities. We utilized the Microdata Integrated Service (MDIS) provided by Statistics Korea from 2013 to 2021. For the data collection reasons, we focused on analyzing the three cities. The results showed that in the initial stages of innovation city development, there was a significant influx of population from the capital region, leading to some effects on population dispersion and balanced regional development. However, over time, a phenomenon emerged where more people started to move back to the capital region, indicating a problematic trend. Furthermore, the Gyeongbuk Innovation City and Gwangju-Jeonnam Innovation City showed similarities in terms of reasons for migration, age of householder, and number of household members. However, the Gyeongnam Innovation City exhibited distinct characteristics compared to the other two cities. While the reasons for this phenomenon may be diverse, the current situation suggests that the goal of achieving "balanced national development" has reached its limits. Therefore, urgent measures need to be taken for improvement that take regional characteristics into account. Furthermore, in designing the second phase of the public institution relocation plan is required to avoid repeating the same issues and ensure a more thoughtful approach.

Korea's general rural development projects, which has shifted its paradigm to a bottom-up approach, should be promoted in the direction of focusing on the subjective well-being of the residents in rural areas. This study analyzed the effect that a general rural development project impact on the subjective well-being of the residents and the village leader in the relationship the spirituality of leadership, the village's social capital to analyze the impact any general rural areas, attributed the success of development projects with diversified.. The results are as follows: First, the basic living-based projects among general agricultural fishing village development projects have positive effects on the subjective welfare of the residents. Second, it was found that the basic living-based projects and regional income raising projects in general agricultural fishing village development projects had a positive effect on the altruistic behaviors and beliefs of spiritual leadership. Third, as a result of analyzing the effect of the level of general farming and fishing village development on social capital, regional income raising projects have a positive effect on the formation of social capital such as trust and network. Finally, as a result of analyzing the influence of social capital on subjective well-being, it was found that social capital such as trust and network has a positive effect on the subjective well-being of rural residents. In future research, it is required to select more extended research subjects not limited to residents of limited areas, and conduct repeated studies, with expanding the model to include the important variables that affect the subjective well-being of the residents.

While many criminal studies have focused on the motivation of offenders and avoidance of victimization in the micro perspective, there have been a number of theoretical developments emphasizing space as a direct factor that influences the incidence of crime. The main purpose of this study is to analyze the effects of regional characteristics and violent crime incidence in Korea. Applying diverse spatial econometrics models that have less been utilized in the crime literature, this study finds an important association between spatial accessibility and crime incidence. The results suggest that the type of predominant business and the level of road accessibility affect the vulnerability of areas with respect to the incidence of violent crime. This study concludes with some important implications for urban planners and policymakers with respect to crime control and prevention.

Purpose : To know the smoking status of regional residents and to contribute the development of smoking education program by analyzing the related characteristics and affecting variables. by convenience sampling of total 1,300 regional residents in Daegu. Method : The investigation was conducted with 1,204 residents in mid to small urban area of Gyeongsangbukdo. for 3 months from April 1, to June 30, 2007. Results : 1) The current smoking rate of test subjects was 19.3% and 63% responded as non smoker, and 17.1% of test subjects responded as currently stopped smoking. 2) The smokers' age that habitually started smoking resulted to show the highest distribution at their age of $20{\sim}29$ by including 49.3% in 446 smokers, and 39.6% in ages younger than 19 years old. 3) The subjective health status of test subjects was found to be healthy in 65.1% of nonsmokers. 4) The increase of stress along with the increase of depression significantly had large effects on smoking rate. 5) When the regression analyses were conducted, test subjects' sex, age, religion, current residing area, occupation, the level of health status, the level of stress and the level of depression found to have significant effects, and the influence of these variables was 27.4% by showing an overall significance. Conclusion : Primarily, the average smoking rate of regional residents was slightly decreased, but the smoking rate in juveniles, university students, professional workers, office workers, labor workers and women were found to be increased. Therefore smoking prevention and stop smoking policies have to be enforced with the development of more effective education programs. Secondly, the health status especially the increase of stress along with the increase of depression significantly had large effects on smoking rate. So, it is considered that the responsible government, related organizations and experts should make efforts not only for the improvement of health and but also for the establishment of stress and depression solving measures. Thirdly, the supports and willingness of government and local government for substantial practicing the development of smoking prevention and stop smoking enforcement policy education programs have to be advanced with the systematic backup as the first step of improving health of national peoples.

It is widely accepted that, at present, the SO$_2$ emissions in China are not increasing thanks to the rigorous Chinese government policies. However, with the development of western China, it is possible that the SO$_2$ emission amounts might increase in regional scale. In this study, changes of sulfur deposition pattern and unprotected ecosystem in east Asia due to the sulfur emission pattern changes in China are studied by using the RAINS-Asia model. Five scenarios have been postulated to understand the effects on east Asia, especially, on Korea and Japan. It is found that the increase of SO$_2$ emission in western China might increase the total emission in whole China. And the amount of sulfur deposition from western China on east Asia would be higher than those from eastern China. The deposition amount of sulfur species on Asia is 3.2 Mt when SO$_2$ are emitted from western China only while 2.6 Mt from eastern China only. Generally, Korea and Japan are influenced more by emissions from eastern China than western China. However, if the SO$_2$ emissions from western China increase by 100% while those decrease by 10% in eastern China compared to the base case, the deposition amount of sulfur species on Korea and Japan would be higher than the base case. The fraction of unprotected ecosystem in Korea and Japan for the base case are 50 and 5%. However, if the emissions from western China increase by 100% while those decrease by 10% in eastern China, the fraction of unprotected ecosystem in Korea and Japan would be 52 and 6%.

This paper examines the effects of foreign direct investment (FDI) on South Asian economies' output growth, utilizing recent panel cointegration testing and estimation techniques. Annual panel data on eight SAARC (South Asian Association for Regional Cooperation) member countries' macroeconomic variables over the period 1960- 2013 are employed in empirical analysis. Using various heterogeneous panel cointegration and panel causality tests, a bi-directional relationship between FDI and growth is found. We find evidence for both FDI-led growth and growth-induced FDI hypotheses for the South Asian economies over the sample period. Individual member countries exhibit heterogeneity in terms of the direction or existence of causality subject to their idiosyncratic economic conditions. Among various regressors, FDI, financial development, human capital, and government consumption show the most significant positive effects on output growth. As determinants of FDI, GDP, financial development, human capital, and government consumption are found significant in the region. The bi-directional causality between FDI and growth is found robust to the inclusion of other control variables and using different estimation techniques.

Recently, it has been important not only to evaluate environmental effects but also to assess cumulative and comprehensive effects by the development projects. This paper concentrates on temporal and spatial cumulative impacts on Suji district in Yongin, Gyunggi-do. This paper adopted two methods to assess the cumulative impacts. First, it assesses the temporal change of forest patch size and land cover according to the patch size. Second, it compares housing development zones with the neighborhood. The result of the research appears that the damage is very serious, especially in small forest. The Forest area is changed to farm land, most of them become to built-up area later. In addition, it is assessed that the secondary housing development projects did more harm than the initial one. By assessing the cumulative impacts on Suji district, this research suggests to minimize two kinds of solutions : comprehensive environmental assessments in regional unit and regulation on total forest quantity.
