  • Park and Kim [4], Grabiec [1] studied a fixed point theorem in fuzzy metric space, and Vasuki [8] proved a common fixed point theorem in a fuzzy metric space. Park, Park and Kwun [6] defined the intuitionistic fuzzy metric space in which it is a little revised in Park's definition. Using this definition, Park, Kwun and Park [5] and Park, Park and Kwun [7] proved a fixed point theorem in intuitionistic fuzzy metric space. In this paper, we will prove a common fixed point theorem for a sequence of mappings in a intuitionistic fuzzy metric space. Our result offers a generalization of Vasuki's results [8].

  • This research was conducted to estimate the use and preservation values of Jirisan national park, using a dichotomous choice contingent valuation. Jirisan national park was estimated to have the use value of 6,377 won per visitor. In terms of preservation value was estimated 13,030 won per housed per year. The results of this research show that Jirisan national park generated considerable use and preservation values, exceeding far greater than current admission fees. The findings also indicate that the estimated economic value provides enough justification for the national park service to increase admission fees in order to maintain the quality of the natural environment. This result may contribute to guidance on the pricing policy of national park managers and practitioners, although public policy may be made in the political arena.

  • This study focused on the changes of residential area around the linear park. The goal of this study is to determine the value of linear park at the view of residents and discover the interaction between the linear park and the residential area around it. To investigate this goal, the researcher chose case sites, the regenerated linear park and the uncovered stream park. This study analyzed the site around the linear parks with four points of view, the organization of urban Fabric, architecture, the economic value of the site and the behavior of residents. This research adopted several research methodologies like aerial photograph analysis, road-view analysis, paper research, and field study, observation, and expert interview to approach as both quantitative and qualitative analysis. With that variation characteristic, the researcher determines the influence of linear park through the residential area around them. As the result, linear park gives positive effects of running sustainable residential area around them and acting as the pivot for the residential area. Also for the future, designers must consider this interactive relation between the linear park and residential area with the wide point of view.

  • This study aims at providing basic policy materials to build a basis for supplying and creating urban parks balanced across Gyeonggi province and improving the quality of life of residents through, an extensive analysis of all city parks in cities/counties in Gyeonggi province. The study result showed that first, the number of parks is only 40% of the adequate number and, thus, accessibility of Gyeonggi province residents to parks in neighborhoods is significantly low. Second, a proportion of park types in children's park, neighborhood park, urban nature park is 67% : 24% : 2%, which is adequate in Gyeonggi province as a whole. Third, as for the area of parks per resident, the area of designated park is $17.7m^2$/person, which is over three times of legal requirement in urban planning area ($6m^2$/person). However, created park area is only $5.6m^2$/person, which fails to meet the legal requirement. Fourth, when park area of each city was compared, the areas varied significantly across cities. The Gyeonggi provincial government needs to secure funds aggressively and accelerate setting up and expanding facilities at designated parks located within the current urban areas. The findings from this study should be used as important materials when developing supply & demand policies for urban parks in Gyeonggi province. The study implicates that independent park policies and management by each city/county as well as the establishment and management of a comprehensive park policy at a provincial level is significantly important.

  • Dadohaehaesang National Park is a well-known habitat for a variety of indigenous animals and plants; however, there are no studies on the diversity of macrofungi. To undertake a basic survey of the macrofungi diversity in an unexploited area, we focused on surveying the macrofungi in Dadohaehaesang National Park, Korea, during 2017 and discovered two unrecorded species belonging to the order Polyporales. The two species were identified as Cinereomyces lindbladii and Steccherinum bourdotii based on a combination of morphological characteristics and sequence analysis of the internal transcribed spacer region. We provide macro- and micro-morphological descriptions for these two unrecorded species in Korea.

  • How parks are to be made in the twenty-first century should certainly be different. This is the inevitable conclusion of the recent significant international design competition for Downsview Park in Toronto, 2000. The purpose of this critical study is to investigate new strategies for urban park design manifested in the proposals of that competition and to explore alternative ways of landscape design that could solve the recent crisis of urban parks. Tree City, the winning entry, and other final entries proclaim that city is park and park is city. In this sense, Downsview Park marks the end of traditional Olmstedian parks and the dichotomy between city(culture) and park(nature). Rem Koolhaas and Bruce Mau's Tree City will become the model for urban park design in the near future. There are three reasons for this. First, its design is a strategy rather than a form. We can interpret that Tree City is to be developed over time as directed by six strategies: grow the park, manufacture nature, 1000 pathways, sacrifice and save, curate culture, destination and dispersal. Second, it places faith in landscape as a revenue generator instead of a fiscal liability. Third, its implementation is possible with crude installation, requiring virtually no craft. Koolhaas and Mau intend for Downsview to be an environment that is never actually designed but is formed through natural succession, cultural action, and programmatical insertions. Rather than designed objects and formal solutions, their strategy is to allow the landscape to evolve with changing uses.

  • This study seeks to find new strategies for the development of Tapgol Park and to identify Programs to promote this development. In addition, the study specifies the purpose and meaning of these efforts by revealing social aspects not apparent in the physical form of the site, and reading how these aspects influenced the development of Tapgol Park Because the focus of the study lies in reading cultural aspects of the site which have to be understood within the context of their social circumstances, the study drew materials from mass media such as newspapers and literary magazines, which best reflect these social aspects. Interpreting the over 100 you history of Tapgol Park in a cultural context, the study found a meaningful suggestion that such a small urban place located in a city forms a cultural identity in the course of communicating with its surrounding social situations. The change in the identity of Tapgol Park has been sensitive to changing social circumstances rather than the physical structure of the space. The original function of Tapgol Park as a traditional city park has gradually changed towards strengthening social functions, much like the character of an urban plaza. In the process of change the park developed a unique culture. This park culture, however, came not from the original design but from its close interactions with social circumstances changing over time. At the same time, the change in identity seen in Tapgol Park has not been fresh formed. It can be said that the inertia came into light with the potential powers under the place over the long history having been combined into the then social circumstances. In early 2002, the park re-opened, refurbished as one of the relics of the March 1st Movement. Investigating how cultural inertias that have been developing in various forms to date will change and be maintained in this new paradigm is an important assignment for researchers.

  • The purpose of this study is to prepare a plan for improving the bird habitat environment of Linear Park. To this end, after grasping the status of bird habitats on the Gyeongchun Line Forest Road, a representative linear park in Seoul, the habitat environment was evaluated and the correlation with the bird habitat was analyzed to derive a plan to improve the habitat environment. The results for correlation between diversity of birds and habitat environment were as follows. For the habitat environment inside the park, the order of positive correlation was in the order of park area (0.92), number of insect species (0.87), green area ratio (0.77), average width of linear park (0.74), Biotope area ratio (0.73), Immigration planted species (0.57). Also, for habitat environment outside the park, the bird diversity was influenced in the order of area outside the park (0.88), green area ratio of the park (0.76). Thus, in order to enhance the diversity of birds found in the park, the bird habitat environment inside the park needs to expand the park area, secure insect diversity, enhance green area ratio and ecological area ratio, expand the width of linear park, and lower the impermeable layer. For the bird habitat environment outside the park, wider area, green area ratio, and forest area of the park influenced on better bird habitation while lower ratio of road space and building-to-land ratio influenced on higher bird diversity. It is necessary to create an environment inhabitable for various species of birds and to make a healthy and pleasant city urban system for co-existence of human and living creatures.

Legal Issues of Urban Parks as a Reservation Area in the Initial Legislation on Urban Parks in Korea and the Implementation of the Park Act (1967~1980) (우리나라 도시공원 관련 초기 법률 입안과 「공원법(1967~1980년)」 시행과정에서 나타난 유보지로서 도시공원에 관한 제도의 문제)

  • The Park Act (1967~1980) was the first law to define urban parks in Korea. The urban parks of that time were similar to a reservation area used for other purposes after giving regulation. Because 'the urban park as a reservation area' in the past is a repeated park issue in the present, it is necessary to consider the issues of the original law system that created the cause. From this perspective, this study analyzed the legislation to reserve an urban park by collecting bills and information about the factual relationship between 1960 70s park issues and the Park Act. Analysis showed that the reason for the adoption of different kinds of urban parks in the law of a nature park is that a negative list separated from the Urban Planning Act is required to curb private usage. Inherent in the Park Act, however, was the problem of allowing the encroachment of urban parks by governmental power. (1) The Park Act sets out a wide range of cases to abolish urban park. (2) Unclear setting of governmental power could abuse the urban park. (3) Insufficient standards were able to erode the urban park with large for-profit facilities. (4) The inactivity of the Urban Public Park Committee had reduced democratic decision-making and professional judgement on park issues. Therefore, the Park Act was characterized as infringing on the environment and right to urban parks and took a passive attitude in creating parks and in citizen usage thereof. The Park Act had limitations as a progenitor for establishing the characteristics and concepts of urban parks.
