As Gwangju Gwonbeon(meaning of a gisaeng call-office) was representative Gwonbeon in Honam area, it educated gugak(Korean traditional music) from the period of Japanese occupation to 1951, the year of foundation of Gwangju gugak center. As Gwangju Gwonbeon's later self, Gwangju gugak center was also an institution that local influentials interested in the education of gugak of Gwangju region cooperated and built. Therefore, Gwangju Gwonbeon should be considered when premodern and modern history of gugak in Gwangju is mentioned. However, the studies of Gwangju Gwonbeon as well as related studies are still thin. Previous researches related to Gwangju Gwonbeon are mostly focused on the operation and dance of Gwonbeon. However, Gwangju was a region where Pansori was invigorated. According to "Joseonmiinbogam", a record of gisaeng(Korean geisha) in 1918, gisaengs of Gwangju Gwonbeon were specialized in Pansori as compared with those of other regions. In addition, today, there are many master singers of Pansori heard by people, among persons who were educated and a lecturer in Gwangju Gwonbeon; therefore, their oral statement is important materials for understanding transmission of Pansori in Gwangju. Nevertheless, the relationship between Gwangju Gwonbeon and Pansori was not studied yet. Especially, oral statement of master singers of Pansori related to Gwangju Gwonbeon was collected partly, as a result, it is not recognized as valuable research materials. Foundation of Gwangju Gwonbeon and Gwangju gugak center became an important basis for education of Pansori as early private institute educating Korean classical musicians in Gwangju. And it is also meaningful as the trigger that gugak in Gwangju was begun in earnest. Therefore, the purpose of this study is reconstruct activities of master singers who worked in Gwangju Gwonbeon and Gwangju gugak center and is to examine transmission and value of Pansori in Gwangju from the period of Japanese occupation to 1973, collecting oral statement of master singers related to Gwangju Gwonbeon. Finally, this study might be helpful for expanding the interest in Pansori and activating related studies.

In this paper, controlling shape of optical fiber tip for endoscope was investigated for eliminating blind spot. The blind spot of endoscope is generated by divergence angle of optical fiber, so it is easy to generate blind spot when tightly focusing. In order to eliminate this region, fiber tip is necessary to be controlled as convex or concave. Illumination simulation of convex and concave type of fiber tip in the endoscope was in progress, so the distance of non- blind region was investigated in each case. As well as the simulation, the tip was fabricated as concave shape by UV laser machining. Then the beam radiation was measured to observe the blind region. The result showed that controlling the fiber tip as convex or concave shape makes the narrow blind region of illumination in endoscope.

This paper suggests the strategy for attracting FDI in Gwangju and Jeonnam region using the secondary data collected by homepage of Ministry of Knowledge Economy, Gwangju City, and Jeollanam-do. The strategy for attracting FDI in Gwangju and Jeonnam region is as follows: First, the local governments of Gwangju and Jeonnam must progressively attract FDI by adjusting to the Korean government's regional industry policy direction. Second, in order to attract FDI consistently, the local governments of Gwangju and Jeonnam must enhance the ability of local officials to attract FDI. Third, in order to attract FDI effectively, the local governments of Gwangju and Jeonnam must build a complete system to support FDI. Fourth, in order to attract FDI effectively, the local governments of Gwangju and Jeonnam have to apply different investment incentives according to FDI effectiveness. Fifth, the local governments of Gwangju and Jeonnam must consistently support foreign companies in order to induce FDI expansion by foreign companies which have already invested in the Gwangju and Jeonnam regions. Finally, in order to attract FDI consistently, the local governments of Gwangju and Jeonnam must improve the negative images and living environments of the Gwangju and Jeonnam regions.

Bloom syndrome protein (BLM) is a pivotal RecQ helicase necessary for genetic stability through DNA repair processes. Our investigation focuses on the N-terminal region of BLM, which has been considered as an intrinsically disordered region (IDR). This IDR plays a critical role in DNA metabolism by interacting with other proteins. In this study, we performed triple resonance experiments of BLM_220-300 and presented the backbone chemical shifts. The secondary structure prediction based on chemical shifts of the backbone atoms shows the region is disordered. Our data could help further interaction studies between BLM_220-300 and its binding partners using NMR.

Citizen participation or resident participation is perceived as an effective way to correspond to the diverse urban problems, especially in the area of residential environment improvement projects and community activities. As the leading city of the Honam region and a core middle city leading the development of the southwestern region, Gwangju city is planning and under-developing new Housing Complexes and Urban Renewal Projects. The purpose of this study is to identify the perception of Gwangju citizens on resident participation in community activities to suggest diverse strategies for improving quality of citizen's life and making better living environment. For the research purpose, 1,380 questionnaires were distributed to the Gwangju citizens who live in 5 autonomous districts -Dong-gu, Seo-gu, Nam-gu, Buk-gu, and Gwangsan-gu- and 601 were used in data analysis. Although citizens in Dong-gu showed the lowest settlement consciousness, they required the highest level of need for resident self-help activities. Contrastingly, Seo-gu showed the highest level of settlement consciousness and the lowest need for resident self-help activities. Based on the results, high quality community facility should be provided to promote residential satisfaction and consciousness of residential participation and self-help activity must be improved. And also, diverse strategies for resident participation including development of resident education programs and search for regional resources should be covered in further research.

Objective : Balloon cells and dysplastic neurons are histopathological hallmarks of the cortical tubers of tuberous sclerosis complex [TSC] and focal cortical dysplasia [FCD] of the Taylor type. They are believed to be the epileptogenic substrate and cause therapeutic drug resistant epilepsy in man. P-glycoprotein [P-gp] is the product of multidrug resistance gene [MDR1], and it maintains intracellular drug concentration at a relatively low level. The authors investigated expression of P-gp in balloon cells and dysplastic neurons of cortical tubers in patients with TSC. Methods : An immunohistochemical study using the primary antibody for P-gp, as an indicative of drug resistance, was performed in the cortical tuber tissues in two patients of surgical resection for epilepsy and six autopsy cases. Results : Balloon cells of each lesion showed different intensity and number in P-gp immunopositivity. P-gp immunopositivity in balloon cells were 28.2%, and dysplastic neurons were 22.7%. These immunoreactivities were more prominent in balloon cells distributed in the subpial region than deeper region of the cortical tubers. Capillary endothelial cells within the cortical tubers also showed P-gp immunopositivity. Conclusion : In this study, the drug resistance protein P-glycoprotein in balloon cells and dysplastic neurons might explain medically refractory epilepsy in TSC.

This paper presents an adaptive interpolation filtering scheme for the High Efficiency Video Coding (HEVC) standard. In regards to interpolation for motion estimation and compensation, the conventional HEVC employs 8-tap and 4-tap filters for luma and chroma samples, respectively. Coefficients in such filters are determined by discrete cosine transform (DCT). In the proposed scheme, boundary strength values are stored after the execution of the deblocking filter. For each block, the sum of boundary strength values is calculated to indicate whether its region is complex or simple. Consequently, based on the region classification, 12-tap and 8-tap interpolation filters are used for complex and simple regions, respectively. This process is applied to luma sample interpolation only. Simulation results show 1.8% average BD-rate reduction compared to the conventional method.

FANCJ is a DNA helicase which contributes genome stability by resolving G-quadruplex DNA from 5' to 3' direction. In addition to main ATPase helicase core, FANCJ has the protein binding region at its C-terminal part. BRCA1 and BLM are the binding partner of FANCJ and these protein-protein interactions contribute genomic stability and the proper response to replication stress. As the first attempt for studying FANCJ-BLM interaction, we prepared BLM binding region of FANCJ and characterized with CD and NMR spectroscopy. FANCJ (881-941) with N-ter 6xHis was purified as the oligomer. Secondary structure prediction based on CD data revealed that FANCJ (881-941) composed with ${\beta}$ sheet, turn and coils.$^1H-^{15}N$ HSQC spectra showed nonhomogeneous peak intensities with less number of peaks comparing than the number of amino acids in the construct. It indicated that optimization should be necessary for detailed further structural studies.

The Gwangju Stream is a major tributary of the Yeongsan River. To maintain environmental and ecological functions in the stream, the flow is secured by natural water from the Mudeung Mountain as well as waters discharged from Lake Juam and the Gwangju sewage treatment plants. A substantial amount of water is supplied into the upper reaches of Gwangju Stream from Lake Juam. To examine the ecological effects of the water input from Lake Juam on the Gwangju Stream, a field survey of phytoplankton community species and an evaluation of water properties was conducted at five stations, from station GJ1 before the inflow to station GJ5 in the lower region. Nutrient levels decreased in the vicinity of the Lake Juam inflow, suggesting that this water inflow can contribute to the reduction of eutrophication in the stream. The phytoplankton community was mainly composed of Bacillariophyceae, Chlorophyceae, and Cyanophyceae, and the community structure was similar to that of the other study sites located near the water inflow regions. The inflow of water from Lake Juam can affect water quality and the phytoplankton community over a limited area, reducing eutrophication and increasing water flow in the Gwangju Stream.

The economic development system of Korea is based on export-oriented strategy and the free trade agreement. So Korea is trying to conclude the free trade agreement with China, Japan, and EU. The reason is that Korea will have more chances to develop there economy scale and trade surplus, but it will give the worst economic situation. The research showed that the effects of FTA on Korea's GDP will be much greater than China's and Korea's trade surplus with China will expand in the manufacturing sector, but agricultural and marine products are layed in opposite situation. Especially comparing with other Provincial, Gwangju Jeonnam has a relative importance portion of agricultural and marine products. So, Gwangju Jeonnam have to prepare the effects of agricultural and marine products under the Korea China FTA.
