  • This study analyzed the relationship of land cover type, urban temperature in Gimhae city, Gyeongsangnam-do, South Korea. Date were used for land cover map, MODIS LST, and detailed temperature data on the Korean Peninsula based on RCP between 2000 and 2010. The correlation between urban area and surface temperature was 0.417, 0.512 for agricultural area and -0.607 for forest area. The correlation between surface temperature and air temperature was 0.301. The relationship with air temperature was analyzed as 0.275 for urban area, agriculture area 0.226, forest area 0.350. Urban and agricultural areas showed increased surface and air temperature as the area increased, while forest areas showed opposite improvements. In structural equation models, urban and agricultural areas had direct effects on the rise of surface temperature, whle forest areas had direct effects on the reduction of air temperature. In the future, it is necessary to use measured temperature data near the surface to understand the relationship between surface temperature and temperature according to the changes in spatial characteristics, which will prepare measures for urban heat island mitigation at the level of urban and environmental planning.

  • The purpose of this study is to improve the private utilization of military welfare facilities that are aging or underutilized in urban areas. It also aims to develop ways to strengthen cooperative win-win strategies between the military and local communities. The use of military welfare facilities by the private sector refers to activities where the private sector generates additional benefits or added value by allowing the use of these facilities, including both private use and improvements to facilities or development of land through private sector involvement. From the perspective of the city and the locals, military welfare facilities are perceived as resident-friendly and excellent urban resources that can promote reciprocal satisfaction between the military and local communities. From the perspective of the military, military welfare facilities are important for enhancing the welfare of military personnel. However, they often face limitations in providing various welfare services due to the aging of facilities and limited operations with a single purpose. The improvement of private utilization of military welfare facilities will bring diverse reciprocal benefits to the military, the city, and the locals. Above all, improving the private utilization of military welfare facilities can help the military and local communities jointly address diverse urban issues. To establish cooperative governance and find flexible and diverse development strategies that can promote the welfare of the military and enhance the quality of life for the locals, it is important that both the military and local communities make continuous efforts.

  • The purpose of this study was to investigate the consciousness of dietitians who provide the basic data for the utilization of traditional food in school food service. The conclusions of this study are as follows. The rate of recognition and awareness of traditional Korean food as the pursuit of learning about socio-demographic was generally high, and was remarkable in the elderly dietitians who have worked for a long term. The way how they learned about traditional Korean food was through media, school education, books, and home education, in order. Also, the dietitians who are relatively older or have worked for a long term have pride in traditional food because it suited their taste and was our traditional food. However, it was difficult to provide the food to school food service because the cooking process is complex, and students don's prefer it. Accordingly, improvements of recipe with use of traditional Korean food in school food service are urgently required. The dietitians in Gwangju City in Jeonnam province felt the need to make a standard traditional Korean food recipe, and the demand was especially the strongest among dietitians who have worked from 6 to 10 years. They suggested that the standard recipe should be made by the Korean Dietetic Association, dietitians working at school, Ministry of Education & Human Resource Development, professors majoring in Food & Nutrition, and Ministry of Health & Welfare in order.

  • To manage national territory and cadastral data efficiently, accuracy and cost-efficiency in cadastral boundary surveying is inevitable. The efficient management of cadastral data is a very important element in national land management. Survey techniques are being introduced. Recently, improvements in survey techniques have been made with the development of satellite surveying, Allowing accurate and fast surveys. If we can calculate the output accurately in real-time in survey fields, it will open a new method in cadastral detail surveying. According to the classification on Law of cadastral surveying, Cadastral surveying can be divided into cadastral control point surveying and cadastral detail surveying. The control point survey can be divided into cadastral triangulation surveying and cadastral traverse surveying. The detailed survey is usually perform by plane surveying. Among these, cadastral detail surveying will be reviewed in this study. In this study, the combination of the satellites, such as US managed GPS and Russian managed GLONASS was used. In the satellite survey in downtown, data interruption symptoms arose(according to the mask angle of the satellite). Therefore; we combined the satellites to get date more accurately. A block of Haewoondae New City in Busan, Korea, which has Numerical Cadastral Law was selected as the sample area for this study. Block II and III are surrounded by high rise apartments. One side of Block I and IV is level ground and the other side is full of high rise apartments. Especially, Block II is surrounded by high rise apartment houses with 20 meters width. In the results of the study Block II did not satisfy the allowable precision, while Block I, II and IV satisfied the allowable precision of the enforcement regulations of Cadastral Law. Therefore, it is judged that the traditionally used Total Station method should be used for supplementary survey on Block II, in stead.

  • This study was performed to analyze the effects of a water circulation green area plan on non-point source pollution in Gimhae South Korea. A quantitative analysis of Arc-GIS data was conducted by applying a watershed model based on Fortran to investigate the changes to direct runoff and pollution load. Results showed that prior to the implementation of the water circulation green area plan in Gimhae, direct runoff was $444.05m^3/year$, total biological oxygen demand (BOD) pollution load was 21,696 kg/year, and total phosphorus (TP) pollution load was 1,743 kg/year. Implementation of the development plan was found to reduce direct runoff by 2.27%, BOD pollution load by 1.16% and TP pollution load by 0.19% annually. The reduction in direct runoff and non-point source pollution were attributed to improvements in the design of impermeable layers within the city.
