To vitalize the link program of Korean long-term care insurance system to community-based services for non-eligible people, we analysed the claim data from the Korean National Health Insurance Corporation (NHIC), and conducted a questionnaire survey to charging employees of elderly service department at local governments. The subjects were all 81,377 people, 57,454 of them were arranged to community-based services. The link program was more necessary among the missed subjects rather than the arranged people due to the need for physical or psychological assistance. By the result of the survey to the local government employees, 59.5% of subjects responded their proportion of link service was over 10% and under 20%, and 54.3% of them responded their job boundary are not clear. Major type of linking was notification the subject list to local government, 91.4%; proportion of periodical notification on the status of their service link were 57.1%, only 7.1% were followed to manage after the link. Difficult factors at the link process were pointed out the overload by other side work, deficiency of resources, rigidity of priority of link, and so on. Considering these results, to vitalize the community-based services to the non-eligible people, it may be essential the active participation of the subjects, construction of parts working in coordination among the institutions including NHIC, local governments, and service providers; development of various services for maintenance or promotion of the non-eligible peoples' health and functional status; and active participation of institutions from the third sector, and so on.

Nutrient (i.e., nitrogen and phosphorus) budgets are required under a 'Livestock Excreta Survey'. A nutrient budget is one of the agri-environmental indicators that calculates the difference between the inputs and outputs of the amount of nutrients within a certain boundary and for a certain time period (e.g., 1 year). In this study, a nutrients budget model was developed to effectively determine the surplus of nutrients within a region in Korea. The C# program language was used in order to facilitate the deployment of a graphical user interface (GUI) and to enhance compatibility. Also, the model was developed on Windows OS, which is the commonly used operating system in Korea. The model was based on the OECD/Eurostat nutrient budget method, and it was modified to consider manure composting procedures as well. There are key features of the nutrient budget model, including directly use of the original data sets from various input and output sources, and a collectively exchange of the address in different formats. The model can quickly show the results of various spatial and temporal resolutions with the same data, as well as perform a sensitivity analysis with coefficients and easily compareresults using tables and graphs. Further, it would be necessary to study the extension of the scope of utilization, such as the application of various nutrient budget methods. It would also be helpful to investigate both pre and postprocessing information such as linking input data through online systems.

Otters, designated as Class I endangered wildlife due to population declines resulting from urban development and stream burial, have seen increased appearances in freshwater environments since the nationwide ban on stream filling in 2020 and the implementation of urban stream restoration projects. There is a pressing need for scientific and strategic conservation measures for otters, an umbrella and vulnerable species in aquatic ecosystems. Therefore, this study predicts potential otter habitats using the species distribution model MaxEnt, focusing on Hwangguji Stream in Suwon, and proposes conservation strategies. Otter signs were surveyed over three years from 2019 to 2021 with citizen scientists, serving as presence data for the model. The model's outcomes were enhanced by analyzing 'river nature map' as a boundary. MaxEnt compared the performance of 60 combinations of feature classes and regularization multipliers to prevent model complexity and overfitting. Additionally, unmanned sensor cameras observed otter density for model validation, confirming correlations with the species distribution model results. The 'LQ-5.0' parameter combination showed the highest explanatory power with an AUC of 0.853. The model indicated that the 'adjacent land use' variable accounted for 31.5% of the explanation, with a preference for areas around cultivated lands. Otters were found to prefer shelter rates of 10-30% in riparian forests within 2 km of bridges. Higher otter densities observed by unmanned sensors correlated with increasing model values. Based on these results, the study suggests three conservation strategies: establishing stable buffer zones to enhance ecological connectivity, improving water quality against non-point source pollution, and raising public awareness. The study provides a scientific basis for potential otter habitat management, effective conservation through governance linking local governments, sustainable biodiversity goals, and civil organizations.

In this study, the watershed and water body models were linked for the simulation of the Nakding river flow. This is a pre-step study for the estimation of the effect of the flow and water quality on the climate change. For models of watershed and river flow, the SWAT and EFDC were used, respectively. The runoff discharge at each boundary points for the simulation of the river flow was provided from the drainage basin model. The calculated runoff discharge by the SWAT model was compared with the measured data of the Ministry of Environment at 13 locations along the Nakdong river and 30 locations along the tributary streams. The computed water discharge was shown to be similar with the measured data. For the model calibration and verification, % difference, NSE, and $R^2$ were computed. The computed % difference was within 15% except of a few points. The NSE and $R^2$ were also within a fair level. The Nakdong river flow of 2007 was simulated by using the EFDC model. The comparison with the measured data showed that the model reflected the actual values of low and high flow well. Also, it was confirmed that the acceleration and deceleration in the curved areas were appropriately simulated. The movement of dye injected at the upstream boundary was simulated. The result showed that the arrival time up to the estuary dam was computed to be about 65 days.

This dissertation is considerably studied Faction Genre which is embossed as a new image content, and it is figured out practical used works' possibilities for Korea film production's varieties. Faction, a neologism, which is combined by Fiction and Fact, is a boundary as limits. If authentic history is closed to a truth, it is a record history description method. Also, if unauthorized history is closed to a fake, it is a fictitious history description method. In addition, macro history and micro history are respectively connected to social criticism's matter and personal action, and these can make various analyses, depend on a boundary's limits and personal analysis. On the other hand, history film could be remembered to audience merely history film itself without existed history's fact. However, there are Faction Genre's Genre possibility and film's attraction which indirectness experience of historic fact could be experienced through film. For Faction Genre’s developing solution, there are three cognitive switches; audience's interpretation ability about history film through watching perception, linking between the past and the present for audience through communication with history, audience's considerable decision about history first or fiction first as film writer's interpretation. Above all, hopefully filmic pressure can be shown with historical true to audience. Therefore, it would be Korea Faction Genre's attraction and hope.

Urban infrastructure is a core of urban growth management which concerns with location, time and costs of development. Despite an inevitable link between development density and infrastructure capacity in urban areas, little study have been performed. For this reason, development activities are undergone without any clear evidence or analysis. The main purposes of this paper are to build subject maps of urban infrastructure capacity which illustrate the level of education service and road capacity, and to give reference standard for development decision at given location. For these purposes, the case study of the high-rise multi-purpose buildings in Daegu metropolitan city is performed. The main findings are follows. First, road ratio is high in the CBD and its surrounding areas as well as rural area, and low in areas of manufacturing, parks and military use. Second, educational facility, represented by the number of student per classroom of elementary school, is fairly abundant across the city, especially in the CBD and rural areas. Third, the high-rise multi-purpose buildings have been built in population-losing infrastructure-abundant areas, in general. Based on these results, this study concludes that the high-rise multi-purpose buildings may induce population-inflow and have low possibility to bring about overly dense developments.

This study presents the methodology to link with aerial photos for advancing the accuracy of topographic survey data that is used to calculate water volume in urban stream. First, GIS spatial interpolation technique as Inverse Distance Weight (IDW) and Kriging was applied to construct the terrain morphology to the sand-bar and grass area using cross-sectional survey data, and also validation point data was used to estimate the accuracy of created topographic data. As the result of comparison, IDW ($d^{-2}_{ij}$, 2nd square number) in Sand-bar area and Kriging Spherical model in grass area showed more efficient results in the construction of topographic data of river boundary. But the differences among interpolation methods are very slight. Image classification method, Minimum Distance Method (MDM) was applied to extract sand-bar and grass area that are located to river boundary efficiently and the elevation value of extracted layers was allocated to the water level point value. Water volume with topographic data from aerial photos shows the advanced accuracy of 13% (in sand-bar) and 12% (in grass) compared to the water volume of original terrain data. Therefore, terrain analysis method in river linking with aerial photos is efficient to the monitoring about sand-bar and grass area that are located in the downstream of Dam in flooding season, and also it can be applied to calculate water volume efficiently.

Since their establishment in 1999, Regional Development Agencies in England have been a critical catalyst for sustaining regional development, by linking the central government and the region. Nevertheless, the new Coalition Government formed in May 2010 is to abolish RDAs and is to be replaced by Local Enterprise Partnerships(LEP). This article looks at the performance and the present reform process of the English Regional Development Agencies(RDA). It argues that RDAs have been a sort of laboratory to expose the possibility of realizing the new regionalist approach away from the government-centered approach. Nevertheless, the case of RDAs in England shows that the RDA model is less likely to be effective without substantial devolution. It shows that the extent to which RDAs contribute to the regional economy tends to be much higher in soft infra-centered projects, such as business supports and skills development, than physical infrastructure projects. It argues that the LEP model, which is to replace RDAs, is controversial, especially in terms of spatial boundary and financial structure.

In Korea, several design competition have been conducted to revitalize the cultural function of some areas using under-used space. However, though such sites include public and urban assets inherently, these projects defined their boundary as an isolated architectural or landscape design. Hence, this study will clarify the differentiated design content and process for public regeneration of under-used space through analysis of the case-study. For this purpose, firstly, the public and urban assets of under-used space will be analyzed to prove that it should be handled with wider boundaries and perspectives. And then, this study will reveal the limitation of design contents and process of Korean design competitions linking to the regeneration of under-used space after analyzing several case studies. Lastly, some differentiated design inducements conducted by the City of Oslo for the each regeneration plan of under-used space will be deducted, focusing on the fact that those projects have been implemented in more urban and connected ways. As a result, this study is strongly aiming to insist that the revitalization of under-used space should not be implemented by advertising a poetic symbolism. Instead, it must be an practical integrated plan emphasizing the connectivity with surrounding environment and diverse plan.

As a result of analyzing the forming and the transformations of Seokjojeon Hall garden by linking it to the changes of Deoksugung Palace influenced by the social atmosphere, the Seokjojeon garden can be classified into four phases. The first phase starts from 1896 to 1914. Gyeongungung was built in the late 19th century(1896-1897) as an official palace and Junghwajeon Hall and Seokjojeon Hall was built for Gojong. J.M.Brown was in charge of the construction of Seokjojeon in the beginning but H.W.Davidson saw the end also set up the garden. In the process of forming the garden the incorporating of Dondeokjeon Hall and the demolishing of the west wing corridors of Junghwajeon Hall occurred. At this phase of the garden a statue of an eagle was put up in the garden but was soon taken down. The shape of the garden was quiet simple with a central axial pathway, a round assorted flower bed placed in front of Seokjojeon Hall. The second phase starts from 1915 to 1932 which lasted for 17 years. At the last years of the Great Han Empire the duties of Gungnaebu(宮內府) was transferred to Leewangjik(李王職) in 1911 and a research on the existing buildings was done by Jujeonkwa(主殿課) in 1915. According to the research drawings, the garden still maintained the axial pathway formed in the previous phase but the garden had an asymmetric form. The flower bed was formed in a round shape and an open-knot technique and boundary plantation was applied to the garden. The third phase starts from 1933 to 1937 and is the period when Seokjojeon Hall was made public. By the year of 1932 many buildings of Deoksugung Palace had been demolished in the preparation of the opening of Seokjojeon Hall as a permanent exhibition hall. The central axial pathway still remained in the new garden and added a pond with a turtle statue in the center. The fourth phase starts from 1938 until the liberation from Japan and is the period when Deoksugung Palace became a park. Yi Royal-Family Museum was built and linked to Seokjojeon Hall with a bridge and the garden transformed into a sunken garden. The garden adopted a fountain and a pagora. Despite the minor changes in the after years the garden still posses most of its form from the fourth phase. As we can see the current garden of Seokjojeon Hall is not the same as the initial garden and therefor the importance of this study lies in the fact that modifications to the statements regarding to Seokjojeon Hall garden should be made.
