The purpose of this study is to examine the archetype of the Gyeongju Castle walls and the facilities around it to bring together previous studies and identify the specific scale and structure of the archetype. The findings can be summarized as follows. First, we verified the exact location and dimensions of the castle through an over-lay of land registration maps from the Japanese colonial period, land registration maps from the present day, cadastral maps, and excavation records. Second, the dimension of the rampart and fort of the castle were discovered by combining and analyzing historical evidence, modern research data, historical site studies from the Japanese colonial era, and maintenance records. Third, the historical records related to the yeojang (rampart sub-wall) formats in the Joseon Dynasty were used to examine the archetype of the yeojang. This study led to the discovery of the archetype of the Gyeongju castle yeojang in the early stage of King Munjong's reign (1451), and the archetype created after the Japanese Invasion (16th century). And finally, although most of the rampart is not present, the structure of the castle can be estimated based on historical research, and research materials modern and contemporary(excavation conservation field survey). In addition, this study presented a archetype restoration plan for each site, to be used as foundational data for future restoration projects.

Recently, it is imperatively necessary to expand fire services funds for providing high quality of fire services. This study is to propose the plan of funds expansion for fire services to cope with a hefty increase of fire services demands in a local autonomous entity era. As alternatives of funds expansion, the study suggests the increase of fire public facilities tax rate and extracting new funds by establishing local government firms such as fire hospitals and fire repair firms. In addition, the study also proposes establishing a new common fire facilities tax, imposing fire services tax on gas tax, imposing public facilities tax on electricity tax, and transferring fire services expense to a local autonomous entity.

현재 농업용저수지 둑 높이기 사업이 전국 110개 저수지를 대상으로 추진되고 있다. 다양한 효과가 기대되고 있는 둑 높이기 사업과 더불어 농업생산기반시설 및 주변지역 활용에 관한 특별법의 시행으로 저수지 등 농업기반시설 및 그 주변지역을 본래의 기능을 유지하는 범위에서 개발할 수 있게 됨에 따라 다양한 시설물의 설치와 운영을 통해 지역의 수익창출이 가능하게 되었다. 그러나 저수지 수변지역으로 개발계획이 집중되어 있고 추가확보 되는 용수는 하천유지와 농업용수 공급에 주로 활용될 계획이므로 추가확보 용수의 보다 다양한 활용방안을 제고하여 더 많은 이익을 창출할 수 있는 방안이 요구되고 있다. 그 중 하나로 둑 하류지역 농경지의 관개배수체계를 정비하여 추가용수 이용의 효율을 향상시키고 농촌마을과 연계하여 친수공간을 조성함으로서 둑하류 농촌마을 주민의 삶의 질 향상과 경제적 이득을 창출할 수 있는 기회를 제공할 수 있을 것이다. 이와 같은 친수공간 개발은 둑높이기 저수지의 추가용수 확보규모 및 지역의 지형, 토지이용, 사회경제적 특성에 따라 달라질 수 있으나 유형화를 통해 대표적 특성에 대한 표준안을 개발 할 수 있을 것이다. 따라서 본 연구에서는 기초연구로서 둑 높이기 저수지의 특성 및 주변 현황자료를 수집하고 통계적인 기법을 이용하여 5개의 둑하류 농촌지역 친수공간 개발유형을 분류하였으며 지역 및 공간적 분포를 제시하였다.

After Fukushima Daiichi nuclear disaster in 2011, study and maintenance of monitoring systems have been made at home and abroad. As concerns about radioactive contamination of water have increased in Korea, update of maintenance of managing radioactive materials in water is being made mainly by Ministry of Environment. In this study, we analysed current state of monitoring system modification in Japan, the country directly involved and neighboring country. According to the result, Japan modified the legislations first. Then Ministry of Education, Culture, Sports, Science and Technology (MEXT) provides theoretical background of radiological monitoring. And Ministry of the Environment actually watches state of water pollution in public waters and underground water. Finally related agencies like local government are monitoring current state of radioactive contamination in water environment. By region, local monitoring stations share the investigation of the whole country. Also, additional monitoring is running around nuclear facilities. After Fukushima disaster, monitoring for area near Fukushima is added. Among the reference levels, management target value of drinking water and tap water is 10 Bq/kg, and those of public water and underground water are 1 Bq/L. Measuring intervals varied from every hour to once a year, regularly or irregularly depending on the investigation. The main measuring items are air dose rate, gross ${\alpha}$, gross ${\beta}$, ${\gamma}$ radionuclide, Cs-134, Cs-137, Sr-89, Sr-90, I-131, and so on. In comparison, regulations about general public water in Korea need to be modified, while those about area near nuclear facility and drinking water are organized well. In future, therefore, domestic system would be expected to be modified with making reference to the guidelines like WHO's one. As good case of applying international guideline to domestic environment, Japanese system could be a reference when general standard of radioactivity in public water is made in Korea.

The study is carried out to survey the proper management and to propose an eco - friendly separation system through efficient screening and resource recovery of excavated materials containing waste from various excavating fields such as reconstruction of landfill sites for reuse, reclamation of unsanitary landfill and residential land development of waste dumping sites. The current status and screening process and analytical characteristics of the excavated materials containing waste were reviewed. Through the analysis of the samples such as separated combustibles, recyclable soils and residues collected from the on-site visits we were able to understand the characteristics of separated materials and excavated materials containing waste such as calorific value, elementary composition, TOC, foreign material content and LOI. It has been found that elimination of the moisture of excavations, removal of attached soil from the surfaces of the excavated combustibles and the quantitative supply method of the input devices are the main operating factors as essential factors for the optimal separation of excavated materials containing waste. For efficient management and recycling of excavated materials containing, it is necessary to set criteria of ash content in separated combustibles and criteria organic matter content in separated soils.

Recently, rural areas are rapidly developing, while existing infrastructure is inadequate and aging compared to developing rural areas. The most representative of these is the sewer system. Therefore, in this study, the rural area of Gyeonggi A city was selected as the study area and analyzed the effect of the sewer maintenance business on the operation of the sewage treatment plant. The analysis items were pollutant treatment efficiencies, the changes of inflow sewage amount, sewage concentration, influnet load, and C / N ratio by comparing before and after the development. As a result of the analysis, the sewage amount increased significantly after the development, and the sewage concentration increased after the development and the load of the sewage in the wastewater treatment plant also increased after the development. And improvement and management of inflow of unidentified water such as infiltration water and influent water in the sewage pipe was improved due to improvement of sewage pipe, which is considered to have affected the increase of C / N ratio and the improvement of TN and TP removal efficiency. The results of this study can be used as a representative example of the sewerage maintenance project in the rural area that positively influenced the operation of the sewage.
