This study was conducted with the purpose of suggesting alternatives for the efficient operation of senior day care facilities in 22 cities and counties in the Jeonnam region by analyzing the efficiency of senior day care facilities. The analysis data for the study used the National Health Insurance Corporation's long-term care insurance for the elderly (2022), the Input variables were the number of facilities, the number of workers, the number of affordable, and the number of senior long-term care insurance recipients and the Output variables were the the number of users. As a result of the analysis, CCR was most efficient in Goheung-gun, Gokseong-gun, Gwangyang-si, Boseong-gun, Yeongam-gun, and Jindo-gun, BCC was most efficient in Goheung-gun, Gokseong-gun, Gwangyang-si, Gurye-gun, Damyang-gun, Boseong-gun, and Jindo-gun, and SE was most efficient in that order: Jindo-gun, Gokseong-gun, and Gwangyang-si. It turned out to be a super efficient area. In the contribution analysis, the number of affordable and workers variables were found to be variables that had a large impact on efficiency contribution. In the improvement potential analysis, the number of facilities variable was found to be a variable that had a significant impact on efficiency. Therefore, for the efficient operation of senior day care facilities, we suggest adjusting supply and demand, such as the number of facilities and affordable, and suggest that training programs to strengthen the expertise of workers who contribute greatly are required.

To examine the forest structure and variation of samara and leaf shape of Acer pictum subsp. mono (APSM), We investigated forest structure and samara angles and length, and leaf shape in three natural population of APSM in Yanggu-gun, Youngyang-gun and Kwangyang-si from June 2012 to October 2013. Mean importance percentage (MIP) of APSM is shown lower values in Yanggu 19.8%, in Youngyang 22.0%, and in Kwangyang 17.1%, respectively. In middle layer, importance percentage (IP) of APSM is shown lower values than that of Acer pseudosieboldianum and Carpinus cordata. In lower layer, importance percentage (IP) of APSM is shown lower values in Yanggu 1.8%, in Youngyang 1.9%, and in Kwangyang 0.0%, respectively. From these results, MIP of APSM in natural population might be reduced in future. Angles between wings and samara length are significantly different between districts. APSM with seven palmate vein leaf are distributed more frequently at Kwangyang and Youngyang than Yanggu. Percentages of biserrate leaf is shown in Yanggu 0.6%, in Youngyang 15.8%, and in Kwangyang 20.4%, respectively. These results implies genetic variation in natural APSM population and further studies on the genetic variation analysis in natuel population of APSM should be needed.

The objectives of this study were to evaluate the extent of heavy metals(As, Pb, Cd, Hg)accumulated in sediments of the Kwangyang Bay, and to investigate bioaccumulation of heavy metals(As, Pb, Cd, Hg) in shellfish(Ruditapes philippinarum) commonly found in the intertidal zone of the Kwangyang Bay. The data was also compared with that of Namhae and Kohung intertidal zones, which were regarded as control stations in this study. Substantial geographical variations in heavy metal concentrations in the sediment samples were found. However, heavy metal concentrations in the sediment collected from the intertidal zones of Yochon(stations I, J) and Myodo(stations G, H) close to Yochon Industrial Area exhibited relatively higher heavy metal concentrations, compared to those from other intertidal zones(stations A, B, C) adjacent to POSCO at Kwangyang Bay. In addition, stations A, B, C showed lower heavy metal concentrations in the sediments than controls(K, L). The annual mean concentrations of the heavy metals in the shellfish from the stations(G, H, I, J) were significantly higher than those from other stations(A, B, C, D, E, F). Nevertheless, heavy metal accumulation in sediments was not reflected in bioaccumulation of heavy metals in shellfish, probably indicating that interactions between the heavy metals in sediment and shellfish might be poor in the current study area, Kwangyang Bay.

The surges caused by the typhoon “Maemi” which struck the southern coast of Korea are analysed in Kwangyang Bay on September 12, 2003. The deviations of the high water level were 93∼108 cm and the maximum deviations of the water level (maximum surges) were 176∼196 cm in Kwangyang Bay during the typhoon “Maemi”. The major parameters of the maximum deviations of the water level are as follows: Analysis shows that the pressure drop increased the sea level by 59 cm, the flood of the Sumjin River by 4-5 cm and the external surge propagation and wind setup by 113∼132 cm. During the typhoon “Maemi”, the highest high water recorded in Kwangyang Port (PT3) is 460 cm, which is higher by 5 cm than the highest high water (455 cm) with return period of 100 years estimated in planning the Kwangyang steelworks (POSCO) grounds and higher by 15 cm than the observed highest high water (445 cm) recorded during the typhoon “Thelma” on 1987. Thus, the highest high water caused by the typhoon “Maemi” is higher than the extreme highest high water for the last 20 years in Kwangyang Bay.

Halophytes are physiologically adapted to withstand the high salinity of water and saline soil. This study was conducted to elucidate the distribution of halophytes and hydrophytes in the Jungseonpo River (Sacheon-ci, Gyeongsangnam-do), Gwingok River (Hadong-gun, Gyeongsangnam-do), and Gwangyangseo River (Gwangyang-ci, Jeollanam-do) in Korea. A total of six species of halophytes and ten species of hydrophytes were collected in the Jungseonpo River. Halophytes in the Gwingok River and Gwangyangseo River numbered five species and 11 species, respectively. Hydrophytes in the Gwingok River and the Gwangyangseo River numbered 13 species in five families and 16 species in eight families, respectively. Of these, Phacelurus latifolius, endemic to the west and south coast of Korea, is an endangered species in the context of investigating the ecology and conservation of halophyte species. Many individual halophyte species have been diminished due to reduced habitable area caused by sand dune destruction. The rivers in the three areas on the south coast were also different in terms of distribution of salt plants due to regional differences, and they were all different from the well-developed west coast. Seven species, including Rosa wichuraiana, have been added to South coasts compared to past records.

This paper is concerned about applying the AHP(Analytic Hierarchy Process) for a priority analysis of equipment operation plan to improve productivity of the container terminal in Gwangyang port. In this study, main elements of container terminal are assumed as into yard equipment area, transport equipment area, berth equipment area and C/Center area. A questionnaire is used to collect the opinions of equipment operating department and operational planning department. On the whole, the result of the analyses reveals that the most important area is yard equipment area. Examining each department is responses, equipment operating department preferred the C/Center area to other areas, on the other hand, operational planning department preferred yard equipment area. The result of this study suggests some guidelines for deciding priority of operation plan in the container terminal.

Many studies have identified the determinants of shippers' selection of ports, and of these, a number have repetitively cited major elements. However, different researchers came up with somewhat different research results depending on the position and preference of research targets. Accordingly, to deduce the determinants of shippers' selection of Gwangyang Port, appropriate research and analysis is required in addition to literature study. This study first deduced from previous studies the determinants that have influence on shippers when selecting a port and positively analyzed the effects of those determinants on the shippers using Gwangyang Port. In this regard, whether shippers using Gwangyang Port have continuously used the port was set as a dependent variable, and port service, port facilities, location of ports, port costs, and other determinants for port selection deduced in the previous studies were set as independent variables. This study's analysis finds shippers using Gwangyang Port are all influenced by the elements of port service, port facilities, location of ports, and port costs in their selection of Gwangyang Port. Their degree of importance is in the order of port costs, location of ports, port service and port facilities. This indicates that shippers consider port costs and location of ports more important than port facilities in their selection of a port.

This study simulate three-dimensional ocean circulation patterns using the EFDC model in the Kwangyang Bay and Jinju Bay, considering tide, water temperature and salinity. The numerical model results were verified using observed data. The model results well reproduced the observed data. As a result, ocean circulation patterns in the study area show convergence and divergence in the middle area of Noryang waterway and Daebang waterway, the residual flow patterns show typical two-layer circulation. According to the change of the density stratification in the Kwangyang Bay and Jinju Bay, the effect of fresh water is dominant in study area. In the case of Jinju Bay, although it is strongly influenced by the Namgang fresh water, also it is affected by Seomjin River when there is no discharge by Namgang Dam. On the other hand, the stratification of the Kwangyang Bay is relatively enhanced by the discharge of Namgang Dam.
