최근 환경부에서 발표한 「제3차(2021~2025) 강우유출 비점오염관리 종합대책(2020)」에 의하면, 우리나라는 지난 50년간 급격한 도시화, 산업화 과정을 거치면서 불투수면적이 전 국토의 약 22.4%에 달한다고 보고되고 있다. 특히 전체 소권역의 6%에 해당하는 51개 소권역의 경우 불투수 면적률 25%를 넘어서고 있는 것으로 조사되었다. 이러한 불투수면의 증가는 기후변화에 의한 영향으로 토양 침투량과 기저유출량을 감소, 갈수기 하천건천화 심화, 우기 표면유출수 증가를 가중시키며 이로인한 비점오염물질 유입 증가, 수질 악화의 원인으로 작용 될 수 있다. 이에 정부에서는 저영향개발(Low Impact Development, LID) 사업 및 친환경그린인프라(Green Infrastructure, GI) 기술요소를 적용하여 도시지역 기후위기 대응 수단의 일원으로 우수유출 저감, 물순환 구조 개선, 비점오염원을 관리하고자 '그린빗물인프라(Green Stormwater Infrastructure, GSI) 조성 사업'을 추진하여 공공청사를 중심으로 학교, 도서관, 체육시설, 공원 등 적용 범위를 확대하고 있다. 이에 본 연구에서는 기후변화에 가장 취약한 해안도시지역인 경상남도에 위치하고 있으며, 불투수면적이 높고 노후화된 소규모 청사 2곳을 시범 구역으로 선정하였다. 각 시범 구역별 GSI 시설 적용이 가능한 주차장, 화단, 옥상 등의 개선방안을 제시하였으며, 적용 규모를 달리하여 물순환·물 환경 개선 효과를 검증하였다. 검증에는 국내에서 개발된 K-LIDM 모형을 활용한 우수유출저감 및 직접유출체적 산정결과를 통해 물순환 효과를, 국립환경과학원에서 제시되고 있는 '토지계 지목별 발생부하원단위', 수질환경개선 보고서에서 제시된 침투형, 식생형 비점오염저감시설의 저감효율을 활용하여 물순환 저감효과를 분석하여 비교하였다.

This study aims to analyze the changes in land prices and building construction activities before and after exclusion from park district as results of natural park re-planning. Seoraksan National Park, Namhansanseong Provincial Park, and Cheonmasan County Park were selected as study areas, and prices and construction activities were compared between areas remaining in and areas excluded from park districts for ten years after park re-planning. Land prices increased in all three study parks. The largest difference in land prices between remaining and excluded areas occurred in Cheonmasan City Park. Land price increased more in excluded than remaining areas in Seoraksan National Park. Unlike these two parks, the changes in land prices were not much different between remaining and excluded areas in Namhansanseong Provincial Park, which can be attributed to the facts that 1) provincial parks were already developed to certain level even before the exclusion due to its less stringent land use regulation than national parks, and 2) that Namhansanseong Provincial Park was also designated as Restricted Development Zone that has similar land use regulation level to natural parks. Comparison between building density measures before and after exclusion shows that development density generally increased after the exclusion. Building heights mostly increased during 10 years after the exclusion. Building to land ratios and floor area ratios also increased. However, building to land ratios and floor area ratios increased only slightly in Namhansanseong Provincial Park and Cheonmasan City Park, suggesting that in provincial and city parks, land development already occurred as a result of less stringent land use regulation. In conclusion, a national park system significantly restricts property right in natural parks, especially in national parks, which make it difficult to expand existing natural parks and/or establish new natural parks. A remedy for resolving problems related to private lands, such as increasing budget for purchasing private lands and introducing park facilities for local community is urgently required.

Bikes have recently emerged as an alternative to carbon neutrality. To understand the demand for public bikes, we endeavored to estimate travel frequency of public bike by considering the intermediate stops. Using the GPS trajectory data of 'Ttareungyi', a public bike service in Seoul, we identified a stay point and estimated travel frequency reflecting population, land use, and physical characteristics. Application of map matching and a stay point detection algorithm revealed that stay point appeared in about 12.1% of the total trips. Compared to a trip without stay point, the trip with stay point has a longer average travel distance and travel time and a higher occurrence rate during off-peak hours. According to visualization analysis, the stay points are mainly found in parks, leisure facilities, and business facilities. To consider the stay point, the unit of analysis was set as a hexagonal grid rather than the existing rental station base. Travel frequency considering the stay point were analyzed using the Zero-Inflated Negative Binomial (ZINB) model. Results of our analysis revealed that the travel frequency were higher in bike infrastructure where the safety of bike users was secured, such as 'Bikepath' and 'Bike and pedestrian path'. Also, public bikes play a role as first & last mile means of access to public transportation. The measure of travel frequency was also observed to increase in life and employment centers. Considering the results of this analysis, securing safety facilities and space for users should be given priority when planning any additional expansion of bike infrastructure. Moreover, there is a necessity to establish a plan to supply bike infrastructure facilities linked to public transportation, especially the subway.

This study aimed to reveal the establishment process and spatial composition of TaiSho park in modern Busan. The TaiSho park is an athletic park which combines a playground and a rest facilities. The arguments on construction of playground commenced for commemorating Kameyama, Busan director official, when he moved to Taiwan in 1910. First Proposers which construct to sport park were businessman in that time. However, construction of playground was progress as a commemoration business of accession of Taisho Tenno. Playground construction got into stride by the proposal of the Busan mayor Wakamatsu in 1917. When it looks into process of discussion about a site selection candidate, norms of playground site selection are the paly ground which appropriate with effective site area and distance between park and a section of a city, in other hand, those are accessibility and budget. As a result of several arguments and actual site investigation, it was decide to select a site which enters to elementary school, after the isolation hospital relocates. The cost of construction of the TaiSho park is prepared by donation of the Busan civil. The donation fund raising committee was constituted by local commerce and industry people, a company, government, municipal offices and area, and funds was raised systematically. As a result, total amount of construction cost was made from the donation of local civil. The TaiSho park is broadly into two sectors; exercise area and rest and pleasure space. Entrance was set up in three aspects of the park and the subcontract planted. The baseball field took the seat in the central part of the park, and also prepared two tennis courts. Japanese Sumo field was also prepared for the north side of the park. The significance of the TaiSho park in Korea Park history can be summarized in South Korea's first sports park and which was made from the donation of local civil. The remained subjects from this study are to clarify the disappearance process of TaiSho park and a reason why modern Busan people want to get playground.

The purpose of this study is to derive indicators and development directions to be considered when planning new towns in the Seoul metropolitan area as new towns are planned to be built. To this end, the following implications were derived after analyzing the survey data of experts in each field using Frequency Analysis and Analysis of Variance(ANOVA) technique. First, the assessment results of the existing first and second phase new towns showed that there were many negative assessments of citizen participation and information sharing, smart technologies and services, social and cultural diversity and inclusion. Regarding the third phase new town, experts said that the most important indicators are accessibility and convenience of transportation, environmental comfort, quality and service of residence. In addition, experts cited the superiority of landscape/design, jobs/self-sufficiency and social/cultural diversity as important indicators. Second, after examining whether the perceptions and assessments of experts differ depending on individual characteristics such as gender, age, occupation, and professional field, the first and second phase new towns showed significant differences only in "gender", and the third phase new town had significant differences in "gender" and "professional field". Third, experts thought that changes in population structure, industry and jobs, quality of life and diversity, environment and climate change, and social and residential welfare should be considered important in the planning of third phase new town. In addition, experts considered expanding park and self-sufficient land as important in the land use plan, and ranked eco-city as a desirable type of the city, and public transportation facilities, park areas and education facilities as the most important living infrastructure.

Ttukseom was once a suburban area that had a government horse ranch for national use and a naenogpo (area of royal farm land). During the Japanese colonial period, a pleasure ground was built at Ttukseom, and after independence, it has been used as a park through the process of urbanization. This study examines the creation of the Ttukseom Pleasure Ground and the process through which the pleasure ground were transformed to a park. This study also explores its landscape and cultural aspects. In the 1930s, Gyeongseonggwedo (京城軌道), a private railway company, built a pleasure ground at Ttukseom to attract passengers, according to the business model of Japanese railway companies, in which recreational areas were developed near railway routes. Mass media portrayed this area as a "rural landscape" in contrast to the city. The Ttukseom Pleasure Ground emerged as a popular summer resort for Gyeongseong citizens. At the same time, it was managed by Gyeongseongbu (京城府). The city of Seoul began to manage the Ttukseom Pleasure Ground following independence, and development plans for Ttukseom as a pleasure ground or a park were continuously drafted but never implemented. Even after Korea's independence, the operation and use of the pleasure ground did not change significantly from the colonial era. In the late 1980s, the Ttukseom Pleasure Ground became the Ttukseom Han River Citizen's Park, and the sandy beach of the Han River was removed. Nonetheless, the previous facilities and major activities such as an open-air swimming pool, camp ground, and areas for boat recreation remained as major park programs. When the urbanization of Ttukseom was completed, its idyllic image disappeared and it became a park instead of a pleasure ground. Since parks expand their programs, it can be concluded that by providing those kinds of programs, the Ttukseom Pleasure Ground transformed to a park.

This study characterized the spatial and seasonal patterns of light pollution in the Deogyusan National Park and examined the potential effects of light pollution on ecosystems in the park using light intensities derived from VIIRS (Visible Infrared Imaging Radiometer Suite) DNB (Day and Night Band) nightlight images collected in January and August 2018. Results showed that the Muju Deogyusan resort had the greatest light intensity than other sources of light pollution in the park, and light intensity of the resort was much higher in January than in August, suggesting that artificial lights in ski slopes and facilities were the major source of light pollution in the park. An analysis of an urban-natural light pollution gradient along a neighboring urban area through the inside of the park indicated that light radiated from a light pollution source permeated for up to 1km into the adjacent area and contaminated the edge area of the park. Of the legally protected species whose distributions were reported in literature, four mammals (Martes flavigula, Mustela nivalis, Prionailurus bengalensis, Pteromys volans aluco), two birds (Falco subbuteo, Falco tinnunculus), and nine amphibians and reptiles (Onychodactylus koreanus, Hynobius leechii, Karsenia koreana, Rana dybowskii, Rana huanrenensis, Elaphe dione, Rhabdophis tigrinus, Gloydius ussuriensis, Gloydius saxatilis) inhabited light-polluted areas. Of those species inhabiting light-polluted areas, nocturnal species, such as Prionailurus bengalensis and Pteromys volans aluco, in particular, were vulnerable to light pollution. These results implied that protecting ecosystems from light pollution in national parks requires managing nighttime light in the parks and surrounding areas and making a plan to manage nighttime light pollution by taking into account ecological characteristics of wild animals in the parks.

This study investigated factors that are associated with companion animal ownership among urban elderly persons. This study was based on data from 2014 Seoul Survey, and a total of 4,717 people aged 60 years or older were selected for the analyses. Community level data were from 2014 Seoul statistics and they included park area per person, number of elderly recreational facilities, and number of public sports facilities based on 25 districts of Seoul Metropolitan City. This study examined differences between companion animal owners and non-owners concerning individual level factors and community level factors. Factors that are associated with companion animal ownership were examined using multilevel logistic regression analysis. Among individual level variables, companion animal ownership was associated with gender, marital status, income, number of household members, and housing type. Among community level variables, park area per person was a significant factor that is associated with companion animal ownership. Study findings can be used Based on study findings, implications of the study and directions for future research are discussed.
