The water pollution Accident in the South Han River is increasing due to increase of pollutants inflow from small streams from rural areas and reduced flow rate. This study predicted the change of water quality in the main stream of the South Han River due to climate change through the linkage of watershed and water quality models. Also, This study analyzed the effect of water quality improvement on Seomgang and the South Han River by securing the flow during the dry season. According to the scenarios for securing the river flow during drought season, the river flow in the Seomgang is increased up to 2.19 times, and the water quality during the drought season was improved up to $BOD_5$ 20.5%, T-N 40.8%, T-P 53.4%. Also, the water quality of the main stream of the South Han River improved to 5.22% of $BOD_5$, 5.42% of T-N and 7.69% of T-P as the river flow was secured from the Seomgang. The result of this study confirms that securing the baseflow in the Seomgang according to the scenarios for securing the river flow during the dry season has a positive effect on the improvement of the water quality of the rivers in the main river of the Seomgang and South Han River. The results of this study will contribute to the establishment of reasonable management to improve the water quality of the main stream of the Seomgang and South Han River.

With the beginning of systemized research on Latin American region as a part of the third world in the mid-60s, Latin American regional studies in Korea acquired a steppingstone for development through the establishment of Hankook University of Foreign Studies Central & South American Regional Study, the creation of Central & South America Research Center, and Latin American Society established in the mid-80s. Latin American regional studies achieved quantitative and qualitative growth with the natioal globalization policy in the 90s, and research centers related to Latin America in Seoul National University, Pusan University of Foreign Studies, Dankook University, and Sunmoon University have contributed to the activation of regional studies. In spite of such achievements, Latin American regional studies, which have developed with 40 years of history, still possess problems that need to be solved. This study achieves qualitative analysis on theses published from 2000 to March 2001 in main Latin America regional study academic journals in Korea to analyze Latin American regional study trend of the recent 10 years in order to search measures for activating Latin American regional studies. Academic journals used in analysis include "Ibero America Research" of Seoul National University Research Center of Central & South America, Spain, "Central & South America Research" of Hankook University of Foreign Studies Research Center of Central & South America, "Ibero America Research" of Pusan University of Foreign Studies Central & South America Center, and "Latin America Research" published by Latin American Society. According to analysis on publication ratio of published theses according to field, it was presented that culture and politics fields occupied the highest ratio. Social and cultural fields, the elementary studies of regional research which have previously presented a weak research tendency, have achieved noticeable development during the past 10 years. According to analysis on researched nations, Latin America regional study was weighted in particular nations, and nations of economic size and political influence within region were selected as main subjects of research. Furthermore, several nations were not researched at all. For the last 10 years, the depth and width of the Latin America regional study had been decided by the degree of political, economic, social, and cultural significance occupied by the nation. It can be said that studies based on overall understanding on regional countries of Latin America have been relatively weak in individual nation study. Furthermore, studies that separate issues to achieve analysis based on the awareness theory of individual branches can be regarded dominant among studies based on entire Latin America. These studies still possess limitations in failing to deviate from the outline of particular region and topic.

Climate change is an important issue, with many researches examining not only future climatic conditions, but also the interaction of climate and air quality. In this study, a new version of the emissions processing software tool - Python-based PRocessing Operator for Climate and Emission Scenarios (PROCES) - was developed to support climate and atmospheric chemistry modeling studies. PROCES was designed to cover global and regional scale modeling domains, which correspond to GEOS-Chem and CMAQ/CAMx models, respectively. This tool comprises of one main system and two units of external software. One of the external software units for this processing system was developed using the GIS commercial program, which was used to create spatial allocation profiles as an auxiliary database. The SMOKE-Asia emissions modeling system was linked to the main system as an external software, to create model-ready emissions for regional scale air quality modeling. The main system was coded in Python version 2.7, which includes several functions allowing general emissions processing steps, such as emissions interpolation, spatial allocation and chemical speciation, to create model-ready emissions and auxiliary inputs of SMOKE-Asia, as well as user-friendly functions related to emissions analysis, such as verification and visualization. Due to its flexible software architecture, PROCES can be applied to any pregridded emission data, as well as regional inventories. The application results of our new tool for global and regional (East Asia) scale modeling domain under RCP scenario for the years 1995-2006, 2015-2025, and 2040-2055 was quantitatively in good agreement with the reference data of RCPs.

The Ministry of Agriculture and Forestry announced promoting the project, 'Regional Agricultural Clusters,' in Feb. 2004 through 「The Comprehensive Plan for the Agriculture and Agricultural Communities」 and initiated a model project from 2005. The purpose of 'Regional Agricultural Clusters' is to develop regional agriculture by concentrating the resources and capacities of the region and maximizing the effect of integrating related projects. 31 towns in Geonggi and 2 towns (Ganghwa and Ongjin) in Incheon were chosen for the study based on the crop areas of 36 agricultural products from the Agricultural Census in 2000. For those 33 towns, factors such as the top 20 agricultural products, main producing districts and surveys on each towns were considered and we have concluded that these items are good subjects for 'Regional Agricultural Clusters' : We have decided on 18 items for what we call, 'Mini-Clusters,' a cluster in which the item's main producing district is in only one area of the town in question (in 30 projects out of 21 towns). Secondly, we have decided on 11 items for what we call, 'Base-Clusters,' a cluster in which the item's main producing district can be associated by name with the item, the production is sizeable, and can be found in several locations of the town in question (in 13 projects out of 11 towns). Finally, we have decided on 12 items for what we call, 'Broad-Based-Clusters, a cluster which the item's main producing district expands the past the vicinity of the town in question (in 19 projects out of 19 towns).

To enhance the usability of smart agriculture, methods for utilizing smart farm data are required. Therefore, this study proposes a scheme for utilizing regional smart farm data by linking it to services. The current status of domestic and foreign smart farm data collection and linkage services is analyzed. To collect and link regional smart farm data, necessary data collection, data cleaning, data storage structure and schema, and data storage and linkage systems are proposed. Based on the standards currently being implemented for regional smart farm internal data storage, a farm schema, environmental information schema, facility control information schema, and growth information schema are designed by extending the crop schema and crop main environmental factor information database schema. A data collection and management system structure based on the Hadoop Ecosystem is designed for data collection and management at regional smart farm data centers. Strategies are proposed for utilizing regional smart farm data to provide smart farm productivity improvement and revenue optimization services, image-based crop analysis services, and virtual reality-based smart farm simulation services.

근대 지리학 방법론 논쟁에서 가장 주요한 쟁점은 지역 지리학의 학문적 성격에 대한 논란이었다. 그러나 대부분의 논의는 지역 연구의 절차를 제시하기보다는 지역 지리학을 형이상학적으로 정당화하는 데 머물렀다. 본 연구에서는 이러한 견해를 비판적으로 검토하기 위하여 지역 지리학 방법론에 내재하는 전제들 가운데에서도 부분과 전체의 관계에 대한 존재론적 가정을 가장 중요한 준거로서 설정하였다. 대부분의 논의는 유기체론에 근거하여 지역을 복합적 존재로서 인식하고, 생명체와의 비유를 통해 지역의 속성을 파악해야 한다고 주장하였다. 그러나, 단위 지역이라는 전제의 한계와 더불어 단순히 요소들을 열거하는 데에 머물렀으며, 지역의 복합성을 포착하지 못하였다. 이러한 한계는 생활양식이라는 전제 위에서 출발한 데에서 오는 당연한 귀결이었다.

Background: Based on the importance of ceasing smoking programs to control the regional disparity of smoking behavior in Korea, this study aims to reveal the variation of smoke rate and determinants of it for 229 provinces. An evaluation of the relative efficiency of the cease smoking program under the consideration of regional characteristics was followed. Methods: The main sources of data are the Korean Statistical Information Service and a national survey on the expenditure of public health centers. Multivariate regression is performed to figure the determinants of regional variation of smoking rate. Based on the result of the regression model, clustering analysis was conducted to group 229 regions by their characteristics. Three clusters were generated. Using data envelopment analysis (DEA), relative efficiency scores are calculated. Results from the pooled model which put 229 provinces in one model to score relative efficiency were compared with the cluster-separated model of each cluster. Results: First, the maximum variation of the smoking rate was 16.9%p. Second, sex ration, the proportion of the elder, and high risk drinking alcohol behavior have a significant role in the regional variation of smoking. Third, the population and proportion of the elder are the main variables for clustering. Fourth, dissimilarity on the results of relative efficiency was found between the pooled model and cluster-separated model, especially for cluster 2. Conclusion: This study figured regional variation of smoking rate and its determinants on the regional level. Unconformity of the DEA results between different models implies the issues on regional features when the regional evaluation performed especially on the programs of public health centers.

Optimal water management is to efficiently and equally supply an appropriate amount of water by using irrigation facilities. Therefore, it is necessary to evaluate water supply capacity through distribution simulation between the designed distribution rate and re-distributed rate according to the changed farming conditions. In this study, we recalculated the agricultural water supply amount of Geumcheon main canal, which beneficiary area was reduced due to the development of Gwangju-Jeonnam innovation city, and we constructed a canal network using the SWMM model to simulate the change in supply rate of each main canal according to the re-distributed rate. Even though the supply amount of the Geumcheon main canal was reduced from 1.20 m³/s to 0.90 m³/s, it showed a similar supply rate to the current, and the reduced quantity could be supplied to the rest of the main canal. As a result, the arrival time at the ends of all main canal, except for the Geumcheon main canal, decreased from 1 to 3 hours, and the supply rate increased from 4 to 17.0% at the main canal located at the end of the beneficiary area of Naju reservoir.

This study is to analyze the current state, trend, and preference of the three chrysanthemum festivals representing South Korea that are hosted by local governments, and it is to be used as the basic data for preparing effective plans for the chrysanthemum festivals. The study was conducted from April 20, 2013 to November 25, 2017, and literature review, online search, interviews with persons in charge, field survey, and questionnaire survey were performed. As a result of the field survey, all three festivals had their space structures divided, themes decided and space images depicted based on chrysanthemum sculptures. The landmarks of the city, cultural assets, or great figures were selected to the main theme of the major chrysanthemum sculptures. The sculptures were decorated realistically for users to easily recognize the image. The main chrysanthemum sculptures tended to be introduced repeatedly. As results of the current state of visit and preference, it was found that the number of visitors has increased every year, along with revisits. The satisfaction and the preference for the festival were evaluated positively, and the chrysanthemum festival has become a local festival representing autumn, and a resource for vitalization of the regional economy. However, as a result of the survey, insufficient parking space and resting place, change of image of the sculptures, experience programs, and food shall be improved in order to increase the users satisfaction.
