Ducklings collected from three farms, having history of rapid onset and spread of nerve signs including kick spasmodically with legs and opisthotonos, were pathologically, barteriologically, virologically examined. Grossly, multiple petechial to ecchymotic hemorrhages were detected in the swollen liver. Histopathologically, diffuse coagulative necrosis of hepatocytes was characteristic in acute cases. Chronic cases revealed marked bile duct hyperplasia rather than hepatocyte necrosis. Some of these cases exhibited multiple granulomas consisting of macrophages, heterophil, fibrin and necrotic cell debri. Filtered homogenate of livers sampled from ducklings caused embryo death with marked hemorrhage and swollen of liver after inoculation into chorioallantoic membrane. Three strains of Salmonella app.,S montevideo, S hadar, and S give, which were biochemically and serologically identified, weir isolated from ducklings of three farms, respectively. From these results, these ducklings were concurrently infected with duck hepatitis virus and Salmonella spp.

Because fine dust (PM10) has a close effect on the environment, fine dust generated in the climate and living environment has a bad effect on the human body. In this study, the LSTM model was applied to predict and analyze the effect of fine dust on Gwangju Metropolitan City in Korea. This paper uses prediction values of input variables selected through correlation analysis to confirm fine dust prediction performance. In this paper, data from the Gwangju Metropolitan City area were collected to measure fine dust. The collection period is one year's worth of data was used from january to December of 2021, and the test data was conducted using three-month data from January to March of 2022. As a result of this study, in the as a result of predicting fine dust (PH10) and ultrafine dust (PH2.5) using the LSTM model, the RMSE was 4.61 and the test result value was as low as 4.37. This reason is judged to be the result of the contents of the one-year sample.

We studies show that ratio of corpse among cremated bodies in public cremation facilities in metropolitan cities using E-Haneul funeral information system is average 90.1%, which is high, in bigger metropolitan cities with over 2 million of population (Incheon, Busan, and Daegu), but is average 81.4%, which is relatively low, in smaller metropolitan cities with less than 2 million of population(Daejeon, Gwangju, and Ulsan). In addition, the cremated bodies ratio of opening remains is average 17.4% in smaller metropolitan cities with less than 2 million of population, but is average 8.9% in those with over 2 million of population, which is relatively low. Finally, the cremated bodies ratio of dead fetuses is average 1.2% in smaller metropolitan cities with less than 2 million of population, and average 1.0% in those with over 2 million of population, which is low. Based on the above result, we are the following suggestions to improve the effectiveness of funeral facility use by the increase of demand for public cremation facilities in metropolitan cities. First, Busan and Daegu, where the shortage of supply is expected due to the increase of demand for cremation of corpse, need to implement supply expansion policy of public cremation facilities to build or expand cremation furnaces. Second, Daejeon, Gwangju, and Ulsan, where the cremated bodies ratio of corpse is low, need to expand supply through expanded operation from existing 4~8 cremation numbers of public cremation facilities to 11 cremation numbers, which is the level of Seoul Metropolitan City. Third, there should be cremation furnaces exclusively for opening remains to prepare the increase of demand for opening remains in the years with leap month.

This study examines the employment conditions and labour experience of elementary after-school care teachers in South Korea. Based on the empirical data collected through in-depth interviews with after-school care teachers in Gwangju Metropolitan City, the study considers multifaceted problems faced by after-school care teachers in their workplace. The after-school care class is part of educational policies initiated and rapidly expanded by the Ministry of Education, resulting in the substantial increase of non-regular school workers. The irregularization of after-school care teachers illustrates that the common problems faced by female non-regular workers, such as social discrimination, exclusion and inequality, are also transplanted into the typical public sector. In the case of Gwangju Metropolitan City, during the past two years there have been evident increases both in under 15-hour short time contract care teachers and outsourcing of care classes. Temporary part-time contract care teachers suffer relentless job insecurity and experience poor working conditions, exclusion and discrimination within the workplace and labour alienation. In order to minimize the organized resistance of care teachers, school authorities implicitly individualize and isolate care teachers through hierarchization, the division of labour and the spatial division of classes between indefinite and temporary contract teachers.

To examine the geochemical behavior and pollution of soils in Gwangju City, an analysis was carried out for pH, on the contents of metals, and organic carbon. Soil samples were taken from environs areas, industrial areas and downtown areas. The major factor controlling the behavior of metallic elements in the soil was chemical weathering of clay mineral in the environs areas, industrialization, and urbanization. Heavy metals including Cu, Pb and Zn were highly enriched for the samples from central part of downtown area. This indicated that the urbanization and the industrialization affected soil pollution. The results show that soil pollution in a metropolitan city which is caused by harmful heavy metals is severest in the center of the city. In consequence, it is inevitable that practical measures should be taken to prevent soil pollution expansion.
