Cities in Korea have rapidly urbanized and they are not well prepared for natural disasters which have been increased by climate change. In particular, they often struggle with urban flooding. Recently, green infrastructure has been emphasized as a critical strategy for flood mitigation in developed countries due to its capability to infiltrate water into the ground, provide the ability to absorb and store rainfall, and contribute to mitigating floods. However, in Korea, green infrastructure planning only focuses on esthetic functions or accessibility, and does not think how other functions such as flood mitigation, can be effectively realized. Based on this, we address this critical gap by suggesting the new green infrastructure planning framework for improving urban water cycle and maximizing flood mitigation capacity. This framework includes flood vulnerability assessment for identifying flood risk area and deciding suitable locations for green infrastructure. We propose the use of the combination of frequency ratio model and GIS for flood vulnerability assessment. The framework also includes the selection process of green infrastructure practices under local conditions such as geography, flood experience and finance. Finally, we applied this planning framework to the case study area, namely YeonJe-gu an Nam-gu in Busan. We expect this framework will be incorporated into green infrastructure spatial planning to provide effective decision making process regarding location and design of green infrastructure.

This paper addresses the efficient facility placements to adopt a super WiFi network, taking significant considerations as the next generation 'information highway'. Since the super WiFi has a wider geographic coverage by utilizing the white spaces of TV broadcasting which are empty and available frequencies for the wireless communications, it would play an important role in releasing digital divide of the internet access for low populated or mountainous areas. The purpose of this paper is to explore systematic and efficient spatial plans for the super WiFi. For doing this, we applied optimal location covering models to Gurye-gun, Jeonlanamdo. From the application, we presented optimal locations for super WiFi facilities and significant analytical results, such as the tradeoff between the number of facilities and coverage and marginal coverage for establishing super WiFi network. The results of this research would be usefully utilized for decision makers who wish to adopt a super WiFi, to extend wireless networks in a city or build a regional infrastructure of wireless facilities.

Gwangchiryeong, located adjacent to the Korean DMZ, is a mountain pass connecting Yang-Gu, Gangwon-do with In-je. It reaches a height of 800m (2,624ft) and stands on the flank of Mt. Daeam-san, which has an elevation of 1,304m (4,278ft). It is important to survey the flora of Gwangchiryeong in that not only the area encompassing the waterfall and the valley along with dense old-growth forest has various plant species but also it is a way to make out what kind of plant species exist in the DMZ due to the geographical characteristics of Gwangchiryeong adjacent to the Korean DMZ. Therefore, this study was conducted to elucidate the distribution of vascular plants and their value in Gwangchiryeong. The vascular plants that were collected 9 times from April 2014 to September 2015, and consisted of a total of 513 taxa: 88 families, 297 genera, 441 species, 4 subspecies, 62 varieties and 6 forms. Among those observed species, the rare plant species designated by Korea Forest Service were 22 taxa including Hanabusaya asiatica, Paeonia japonica, Saxifraga octopetala, etc. Endemic species were 22 taxa containing Cirsium setidens, Heloniopsis koreana, Salvia chanryoenica, etc. 18 taxa were recorded as naturalized plants and their naturalized rate and urban index were noted as 3.5% and 5.6%. Among the surveyed 513 taxa, edible, medicinal, pasturing, ornamental, timber, dye, fiber and industrial plants were 197 taxa, 154 taxa, 180 taxa, 49 taxa, 24 taxa, 8 taxa, 4 taxa and 3 taxa, respectively.

The boundaries of ROK maritime jurisdictional area remains unclear as two Koreas failed to draw clear maritime boundaries at the armistice agreement and there are no clear maritime boundaries with China and Japan. After the Korean War, the United Nations Command established the northern limit line(NLL) as well as the area of operations(AO) to enforce the DPRK's compliance with the armistice agreement and has been controlling all of the maritime and air activities in the region. ROK also has been controlling the passage of DPRK vessels in the area. Within the AO, third nation vessels have freedom of navigation, Yet, due to the division followed by the Korean War, ROK classifies DPRK as a hostile state and unique controling system is applied to DPRK vessels. Since the establishment of the AO, many changes have been occurring such as adoption of the UN Convention on the Law of the Sea(UNCLOS) and two Koreas' joining the UN. Also, there are continuous inter-Korean conflicts. Therefore, the geographical span of the AO needs to be reconsidered. Furthermore, a legal measure which ensures ROKN vessel's functional capability of controling DPRK vessels must be introduced. This thesis examines post-Korean War DPRK vessel control system in the Korean peninsula as well as how it should be improved.

The commerce and industry of Busan was developed because of good geographical conditions with harbor. After passing its settling-down and diffusing time, Busan has grown in the trade city. Busan has lost the competitive power of the port city since 2000, because of the weakness of its economic power which is caused by the secession of manufacturing industry and the decrease of resident population and foreign tourist. In order to overcome these weaknesses, it is necessary for Busan to take the innovative strategy for the activation of marine tourism. This goal can be achieved by the strong quality of the port city, the coastal terrain, the traditional industry and the international traffic. The aim of this paper is to explore the Innovative Strategy for the activation of marine tourism in Busan and to suggest the following proposal. First, the government must decide the base of marine tourism under the geography viewpoint of the coast and sea, and develope tourism resources after analyzing the identity of marine tourism base. Second, the core part along the selected bases of marine tourism must be constructed the tourism terminal as the landmark of Busan in order to concentrate foreign tourist. Third, after each base of marine tourism must become the resort for tourists, they are able to experience the activity of marine tourism in this resort. Therefore, each base must be specialized. Fourth, each base must be connected with the route of marine tourism Fifth, in order to overcome the off-season of marine tourism, winter tourism goods such as skates, skis, artificial sea-bathing pool, artificial swimming beach, artificial sled, artificial rock wall of coast, hot spring resort of salt water are required to be developed in the center of marine tourism base.

As the demand for finding clearer information amid vast information acquisition increases, the enhancement of academic research services is highly important. In 2019, the Presidential Archives opened the only academic research services among the permanent archives management institutions. This study aims to identify the status of the insufficient use of academic research services implemented in the Presidential Archives, analyze problems and requirements through interviews with users who have used the Presidential Archives for academic purposes and conducted research, suggest a plan to upgrade the research services of the Presidential Archives, and offer a plan to improve the services of archives institutions accordingly. Researchers mostly sought information through an online search, but the information gap was large depending on the background knowledge, and the research scope was reduced because of insufficient information. Moreover, problems occurred regarding search tools, records management, and records disclosure, and most users were unaware of the academic research services. Therefore, the advancement plans entailed reducing the information gap among researchers, improving the search tool functions, creating more detailed descriptions of records, resolving geographic constraints, promoting academic research services and developing content, nurturing subject-specialized archivists, and providing online chatting services.

This study investigated the diversity of butterfly communities inhabiting agroecosystems and examined the effect of latitude and longitude. The ecological characteristics of butterflies inhabiting rural ecosystems, such as habitat preference and food plant range, were also examined. This study was conducted from 2019 to 2022, selecting 10 locations nationwide and conducting line transect surveys every two weeks for four years, confirming a total of 112 species and 21,901 individuals. There was no difference in the number of species and individuals by region, but there was a clear difference in community composition. The most abundant species in rural ecosystems were Pieris rapae, Polygonia c-aureum, Zizeeria maha, and Colias erate, in that order. There was no significant difference in the number of species and individuals by latitude and longitude, indicating no peninsula effect. Habitat preference showed that butterflies preferring grasslands and forest edges were much more common than those preferring the forest interior, and the food breadth was mostly oligophagous, followed by monophagous and polyphagous. Butterflies inhabiting agroecosystems had ecological characteristics that preferred open spaces such as grasslands and forest edges or relatively diverse foods, due to the similarity of the environmental characteristics of the survey points. Through this study, we believe that continuous monitoring is necessary to determine whether climate change, which is currently underway and habitat change are affecting butterflies in agroecosystems.

Health sub-centers(HSCs) have played an important role in primary health care in rural area in Korea. The unification of neighboring HSCs was a strategy to improve the role of HSCs. This study was conducted to reveal the efficacy of the unified HSC established in Yangbuk-myeon, Gyeongju-si in1997. The utilization patterns of HSC and its related factors, and satisfaction of consumer on HSC were compared before and after unification of two HSCs in Gampo-eup, Yangnam-myeon using questionnaire survey, and also the statistics of medical care services and public health services were compared. Four hundred forty nine subjects were questioned in survey, 156 from Gampo-eup, 147 from Yangbuk-myeon, and 146 from Yangnam-myeon. Following unification, the utilization rates and the frequency of visits in Gampo-eup declined. In all three areas, chronic illness was the common factor influencing the utilization and change in frequency of visits to the unified HSC. Following unification, aspects of consumer satisfaction, for example; accessibility and affordability decreased in Gampo-eup, but increased in both Yangbuk-myeon and Yangnam-myeon. The statistics relating to medical care, X-ray examination, home visiting service, vaccination, and health education showed an increase for the unified HSC when compared to the sum of the statistics for the previous two. The execution rates for other public health services were the same, or a little decreased. Clinical laboratory examinations and the issuing of civil affair documents were new services offered by the unified HSC. It is concluded, the overall consumer satisfaction with the unified HSC was improved. In Gampo-eup, where after unification there was no HSC, it seemed to be a barrier to accessing the unified HSC. The effect of the unified HSC, in the respect of medical care and public health services, was not as significant as expected at the time of being established. Therefore, the strategies to reenforce the unified HSC should be developed to provide all residents with comprehensive primary health care services.

A moat is a pond or waterway paved on the outside of a fortress that is one of the facilities to prevent enemy from approaching the fortress wall or classify it as the boundary space, moats had existed in Europe, Asia and the America from ancient times to medieval times. however it is has been disappeared in modem society. In addition, a moat is a great value in historical and cultural sense such as offering a variety of cultural activities and habitats for animals, but unfortunately there is little consideration of its restoration plan. This research is aimed to investigate historical and cultural meaning and significance of moats which had been existing from ancient times to medieval times in the Eastern and Western. For this purpose, this research analyzed concepts and functions in consideration with times and ideological backgrounds of moats in Korea, China, and Japan. Results were as follows: 1. Moats in Korea existed not only in the castle towns of Goguryeo but also in ancient castle towns of Baekje and Silla. Natural moats and artificial moats existed around castles that were built to prevent and disconnect accessibility of enemies In Goryeo Dynasty and Chosun Dynasty, moats were also used as a defensive function. 2. A moat was generally installed by digging in the ground deep and wide at regular intervals from the ramparts, A moat was installed not only around a castle but also in its interiors. Moats outside castles played an important role in stomping the ground hard besides enhancing its defensive power. In addition, water bodies around a facility often discouraged people's access and walls or fences segregated space physically, but a moat with its open space had an alert and defensive means while pertaining its visual characteristics. 3. The moat found at Nagan Eupseong rumor has it that a village officials' strength was extremely tough due to strong energy of the blue dragon[Dongcheon] in Pungsujiri aspects, so such worries could be eliminated by letting the stream of the blue dragon flow in the form of 'S'. 4. The rampart of the Forbidden City of China is 7.9 meters high, and 3,428 meters long in circumference. It was built with 15 layers of bricks which were tamped down after being mixed with glutinous rice and earth, so it is really solid. The moat of the Forbidden City is 52 meters in width and 6 meters in depth, which surrounds the rampart of the Forbidden City, possibly blocking off enemies' approach. 5. Japan moats functioned as waterways due to their location in cities, further, with the arrangement of leisure facilities nearby, such as boating, fishing from boats, and restaurants, it helped relieve city dwellers' stress and functions as a lively city space. 6. Korean moats are smaller in scale than those of the Forbidden City of China, and Edo, and Osaka castles in Japan, Moats were mostly installed to protect royal palaces or castles in the Eastern Asia whereas moats were installed to protect kings, lords, or properties of wealthy people in the west.
