In this study, space allocation with an assessment system for improving the function of the ecological use and function of each space was undertaken to suggest appropriate goals and directions. Ogeum Park, used as the study site, is a stronghold green zone located in the fan-shaped area of the Songpa-gu green zone on a 22ha area site. The assessment system for this study consisted of a total of 3 steps: Step 1 includes the division of the spatial block, Step 2 assesses the proper functioning of each spatial block, while Step 3 includes space allocation and presents improvements for function by space. This study performed a basin analysis with the consideration that Ogeum Park is a forest area and divided the site into a total of 8 areas according to how the sections of land are used. The function of wildlife habitat included an analysis of plant ecology(vegetation type, vegetation layer, potential vegetation), animal ecology(wild birds), and waterways. The function of leisure and use included an analysis of gradients, noise, paths, status of use, and status of facilities. The evaluation of the function of habitat sorted items into native vegetation, vegetation diversification, vegetation potential, animal diversification and potential of animal habitats. The results of grading the evaluation scores by space in the function of habitat showed that the Areas IV and VII, which were 90% of the maximum point, were Grade A, Areas II and V were Grade B at 70% and Area I and VI were Grade C at 50%. Areas III and VIII, which were not found to be beyond the standard of 50%, were excluded. The evaluation of the functions of leisure and use classified items into use potential, use preference, use concentration, use diversification and use convenience. The results of the graded evaluation scores by space in use function, showed areas V and VI as Grade A, or 90% of the maximum score. Grade B, 70% of the maximum score, was given to Areas I and VII. Grade C, 50% of the maximum score, included Areas II, IV and VIII. Area III, graded lower the standard of 50%, was excluded. The study evaluated areas according to a common standard, classified spaces by proper functions into ecological spaces, environmentally-friendly use spaces and use spaces according to the standard of spatial distribution on the basis of the above results through a synthesis of grades of habitat function, leisure function and use. This offers ideas for the improvement of wildlife habitat and environment-friendly use functions by space.

The purpose of the university library's reading room is to provide a space for reading books. However, with the recent increase in use as a personal learning space, discussions have been made on spaces in university libraries. The ultimate goal of this study is to analyze the utilization status of reading rooms in university libraries that exist to support students' learning activities, and then to derive preference factors according to spatial characteristics of each room. For this purpose, we selected "J" University as a research target. The log data was collected and analyzed for one year from various reading rooms in "J" University. Based on 218,939 cases generated from 40,753 users, usage patterns were analyzed according to period and space. Through the analysis results, preference factors for reading room were derived. In addition, the considerations for improving space utilization were proposed. The results of the study can be used in the future to improve space arrangement and space utilization in reading rooms of university libraries.

Increasing complexity of the basin environments makes it difficult for single decision maker to consider all relevant aspects of problem, and thus the uncertainty of decision making grows. This study attempts to develop an approach to quantify the spatial flood vulnerability of South Korea. Fuzzy TOPSIS is used to calculate individual preference by each group and then three GDM techniques (Borda count method, Condorcet method, and Copeland method) are used to integrate the individual preference. Finally, rankings from Fuzzy TOPSIS, TOPSIS, and GDM are compared with Spearman rank correlation, Kendall rank correlation, and Emond & Mason rank correlation. As a result, the rankings of some areas are dramatically changed by the use of GDM techniques. Because GDM technique in regional vulnerability assessment may cause a significant change in priorities, the model presented in this study should be considered for objective flood vulnerability assessment.

The purpose of this study is to gain an in-depth understand of the dwelling needs of residents who are interested in Cohousing. To do this, we interviewed 18 urban residents who wanted a community life; investigated consciousness of neighbor relationships; and analyzed their consciousness of Cohousing residences, preference types, and spatial needs. At first the research has revealed that the neighbor relationships of the participants were not very close and that there was a difference in awareness levels between a 'good neighbor' and 'strange neighbor' with regard to neighbors, though all of the participants required a vitalization of these relationships. Second, Cohousing residence types could be divided into the 'life preferred type' and 'space preferred type', depending on the differences of pursued dwelling interests. These could be further segmented into the 'leisure life preferred type' and 'daily life preferred type', 'public space preferred type' and 'individual space preferred type'. Thirdly, preferences for Cohousing types varied depending on differences in priority with regard to important concepts of the social-physical environment (e.g., community property, effectiveness, naturalness, economic feasibility, and individuality). Finally, we found that the greatest needs were for public gardens and exercise space as aspects of the common spaces. Agreements pertaining to special use were considered as most important during the design process of the common spaces.

Big data has recently been used in various industries such as tourism, medical care, distribution, and marketing. And it is evolving to the stage of collecting real-time information or analyzing correlations and predicting the future. In the tourism industry, big data can be used to identify the size and shape of the tourism market, and by building and utilizing a large-capacity database, it is possible to establish an efficient marketing strategy and provide customized tourism services for tourists. This paper has begun with anticipation of the effects that would occur when big data is actively used in the tourism field. Because the method of use must have applicability and practicality, the spatial scope will be limited to Seosan, Chungcheongnam-do, and research will be conducted. In this paper, to improve the quality of tourism courses by collecting and analyzing the number of mention data and sentiment index data on social media, which reflect the tourist's interest, preference and satisfaction. Therefore, it is used as basic data necessary for the development of new local tourism courses in the future. In addition, the development of tourism courses will be able to promote tourism growth and also revitalizing the local economy.

This study aimed to develop the indicator-based approach to assess water use vulnerability in watersheds and applied to the unit watershed within the Han River watershed. Vulnerability indices were comprised of three sub-components (exposure, sensitivity, adaptive capacity) with respect to water use. The indicators were made up of 16 water use indicators. Then we estimated vulnerability indices using the Technique for Order of Preference by Similarity to Ideal Solution approach (TOPSIS). We collected environmental and socio-economic data from national statistics database, and used them for simulated results by the Soil and Water Assessment Tool (SWAT) model. For estimating the weighted values for each indicator, expert surveys for subjective weight and data-based Shannon's entropy method for objective weight were utilized. With comparing the vulnerability ranks and analyzing rank correlation between two methods, we evaluated the vulnerabilities for the Han River watershed. For water use, vulnerable watersheds showed high water use and the water leakage ratio. The indices from both weighting methods showed similar spatial distribution in general. Such results suggests that the approach to consider different weighting methods would be important for reliably assessing the water use vulnerability in watersheds.

To understand the effect of forest fragmentation on forest-dwelling birds, it is more effective to analyze on the selected specialists than on the whole bird community. We investigated the edge preference of forest-dwelling birds to discriminate habitat specialist species in the interior and on the edge of temperate deciduous forests in central Korea. Point count and line transect census were conducted at Gwangneung forest from February to October. Our result shows that there was no consistent tendency in abundance of birds between in the interior and on the edge because of the different landscape characteristics and the high proportion of habitat generalists. Five habitat specialists in 73 bird species were identified by the differences in both population densities; three forest interior and two forest edge specialists. Asian Stubtail Warblers (Urosphena squameiceps), Pale Thrushes (Turdus pallidus) and Coal Tits (Parus ater) were included in the forest interior group, but Black-billed Magpies (Pica pica) and Black-naped Orioles (Oriolus chinensis) were classified as the forest edge group. We suppose that a selective monitoring on patterns and changes in spatial use of these five habitat specialists is needed to estimate the effects of forest fragmentation in temperate deciduous forests. And, moreover, systematic monitoring methods for field survey should be established based on the point count method and line transect census to ensure the equality of data.

Assessment of vulnerability of water use to climate change include a variety of climate change scenarios. However, in most future vulnerability studies, only the climate change scenarios are used and not the future scenarios of social and economic indicators. Therefore, in this study, we applied the Representative Concentration Pathway (RCP) climate change scenario and Shared Socioeconomic reference Pathway (SSP) developed by IPCC to reflect the future. We selected indicators for estimating the vulnerability of water use, and indices were integrated with a multi-criteria decision making approach - Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). The indicator data utilized national statistics and reports, social and economic scenarios, and simulated results from the Soil and Water Assessment Tool (SWAT) model which reflects climate change scenario. Finally, we derived the rankings of water use vulnerability for the short-term future (2020) and mid-term future (2050) within the Han River watershed. Generally, considering climate change alone and considering climate change plus social and economic changes showed a similar spatial distribution. In the future scenarios, the watershed rankings were similar, but showed differences with SSP scenario in some watersheds. Therefore, considering social and economic changes is expected to contribute to more effective responses to climate change.
