  • Assessment of soil carbon stock is essential for climate change mitigation and soil fertility. The digital soil mapping (DSM) is well known as a general technique to estimate the soil carbon stocks and upgrade previous soil maps. The aim of this study is to calculate the soil carbon stock in the top soil layer (0 to 30 cm) in Jeolla Province of South Korea using the DSM technique. To predict spatial carbon stock, we used Cubist, which a data-mining algorithm model base on tree regression. Soil samples (130 in total) were collected from three depths (0 to 10 cm, 10 to 20 cm, 20 to 30 cm) considering spatial distribution in Jeolla Province. These data were randomly divided into two sets for model calibration (70%) and validation (30%). The results showed that clay content, topographic wetness index (TWI), and digital elevation model (DEM) were the most important environmental covariate predictors of soil carbon stock. The predicted average soil carbon density was 3.88 kg·m-2. The R2 value representing the model's performance was 0.6, which was relatively high compared to a previous study. The total soil carbon stocks at a depth of 0 to 30 cm in Jeolla Province were estimated to be about 81 megatons.

  • The objectives of this study were to investigate soil chemical characteristics for forest rehabilitation and suggest management in abandoned coal mine areas in Hwasun-gun, South Jeolla Province. Total study sites were 8 sites, and soil analysis particular were soil pH, TOC, total-N, C/N ratio, Avail. $P_2O_5$, and CEC. Average soil pH was 5.8 (4.7~6.4). Average contents of TOC, total-N and C/N ratio were 1.1% (0.2~2.0%), 0.08% (0.02~0.13%) and 15.0 (7.9~31.4), respectively. Average Avail. $P_2O_5$ was $8.3mg\;kg^{-1}$ (2.7~15.0) and Average CEC was $13.7cmol_c\;kg^{-1}$ ($9.9{\sim}18.5cmol_c\;kg^{-1}$). Soil pH was decreased according to elapsed time from forest rehabilitation, while TOC, total N and CEC were increased. Av. $P_2O_5$ did not show any relationship with elapsed time. Soil pH was stable comparing with general forest soil in South Jeolla Province (5.1), while contents of TOC and total N were lower than general forest soil in South Jeolla Province (4.9% and 0.18%, respectively). Therefore, sustainable managements such as fertilization for TOC and total N are necessary for good rooting and growth of vegetation.

  • This study analyzed the factors affecting economic growth using multiple regression model and Geographically Weighted Regression in consideration of population, industry and employment, housing and political characteristics on economic growth by region. The analysis results are summarized as follows. First, the total employment growth rate, manufacturing employment growth rate, local election turnout and the level of party consensus between the central and local governments are having a positive impact on regional economic growth. Second, according to the GWR analysis, the population has a positive impact on economic growth in the southern region of Korea, and the increase in the total number of employees has a positive impact on the southern region of Gyeonggi Province, Gangwon Province, North Chungcheong Province and North Gyeongsang Province. Finally, the voter turnout of urbanites is positively affecting economic growth in South Chungcheong Province, Gangwon Province and the southern coast, while North Jeolla and South Jeolla provinces have a positive impact on economic growth as the parties of the central and local governments are equal. The results of this study may suggest the role of local government for regional economic development.

  • This study made a nationwide metropolitan region map on the basis of disaster vulnerability and administrative boundary, and based on it, it divided small-sized regions and constructed disaster history of each region. For the disaster vulnerability, the study wrote slope, aspect, curvature, wetness index, and drainage density, compared and analyzed regions with disaster and geomorphic elements to distinct the factor with high correlations, and based on it, it divided small-sized regions for forecasting and warning system of middle regions(Gangwon province, Chungchung province, and Jeolla province). Through the method, Gangwon region were divided into 4 small-sized regions, Chungchung into 5 small-sized regions, and Jeolla into 6 small-sized regions.

  • 공공서비스의 지역적 불균등을 분석하는 것은 사회복리지리학에 가장 큰 주제 가운데 하나이다. 이 연구는 1885년~2005년 동안 광주광역시를 포함한 전라남도 지역을 대상으로 연구지역의 객관적인 사회복리 수준의 지역적 변화를 분석하기 위해, 군집 분석기법을 비롯한 다양한 사회복리 수준 측정 방법을 사용하였다. 분석결과 지난 20년 동안 연구지역의 전반적인 사회복리 수준이 향상되었다는 것을 확인할 수 있었다. 하지만 도서지역의 경우 사회복리수준의 발전이 상대적으로 미약한 것으로 나타났다. 따라서 도서지역의 사회복리 수준을 개선하기 위한 정책적 방안이 수립될 필요가 있다.

  • This study is to suggest design types and to identify design characteristics of traditional style public buildings. Since the types of such buildings became very diverse recently, proper classification criteria is essential for future design and evaluation. The demand for such buildings is continuously increasing, but the types of design is very varied; thus it seems important to identify the present design conditions, and to be able to suggest desirable directions for better designs. The research analyzes 31 examples of public buildings in Gwangju Metropolitan City and South Jeolla Province, where there are large number of traditional style public buildings than anywhere else in Korea, and tried to analyzed site plan, elevation, space, details and organizes Design types. This study can help to roughly identify the problems of existing design as well as to suggest improvements in the future design.

  • Although Maejeong-Bogam (梅亭寶鑑) is a manuscript, it has attracted considerable attention from academia because of the clear authorship and relevant treatment methodologies. This article is the result of an extensive study on the author and the contents of the manuscript through the use of various data. This article revealed facts which include: 1) Author HAN Bangryeol (韓昉烈) is a Confucian doctor who lived in Namwon area, Jeolla province of Korea. 2) Dr. HAN's other manuscript of Bongseong-Shinbang (鳳城神方) was written before 1814. 3) Maejeong-Bogam (梅亭寶鑑) collects pediatric medical records only and is focused on outbreaks and treatment of smallpox among children. 4) Smallpox was a national concern in the late Joseon Dynasty and doctors of the day developed corresponding therapies. 5) Smallpox Inoculation was carried out in Jeolla Province as early $19^{th}$ in Korea.

  • 다양한 Aureobaisidum속을 발굴하여 흑효모의 유용한 특성을 활용하기 위해 전라도 지역 꽃에서 효모 433균주를 분리하고 분자계통학 및 형태학적 분석을 통해 다양성을 확인하였다. large subunit (LSU) rDNA 염기서열 분석을 기준으로 전라도 지역의 Aureobasidium속을 6그룹으로 분류한 후, LSU와 ITS rDNA 염기서열 분석을 통해 전라도 지역 꽃에서 유래한 효모의 주요 우점종이 Group A와 Group D임을 확인할 수 있었다. GroupB, E, F는 전라남도에만 분포하는 것으로 보아 전라북도에 비해 전라남도에서 다양한 Aureobasidium종이 분포하는 것으로 생각된다. Group A는 A. pullulans, Group B는 A. melanogenum, Group F는 Aureobasidium 신종 후보군으로 분류할 수 있었다. Group C, D, E는 LSU와 ITS rDNA 분석에서 A. leucospermi, A. namibiae, A. subglaciale 사이의 명확하게 분류되지 않았으나 콜로니 형태에서 구분 가능한 특성을 보인 것으로 보아, Aureobasidium은 분자계 통학적 분석방법과 형태적 동정을 병행하여 종 수준 동정을 보완할 수 있을 것으로 생각된다.

  • This study is to suggest architectural types and identify design characteristics of traditional style public buildings of reinforced concrete structure. Because the types of such buildings are very diverse, proper classification criteria is essential for future design and evaluation. The demand for such buildings is increasing, however the quality of design is not quite satisfying, therefore it seems important to identify the present design condition, and being able to suggest desirable direction for better design. The research analyzed 44 examples of public buildings in Southern Jeolla Province, where there are large number of traditional style public buildings than anywhere else in korea. and tried to analyzed the Siteplan and Elevation, Elements and evaluated overall design level of the buildings. The study could be able to roughly identify the problems of existing design as well as the future possibility of design which could be improve in the future.
