  • Zostera marina (ZM), a type of seagrass registered as a marine protected species in South Korea, provides valuable ecosystem services to humans, such as improving marine water quality, providing food, spawning grounds and habitats for marine life, and absorbing carbon dioxide. Therefore, the government is seeking to preserve ZM by designating ZM-protected areas. This study examined the public willingness to pay (WTP) for the preservation of ZM using contingent valuation. The one-and-one-half-bounded model was adopted for WTP elicitation, and the single-bounded model was also applied for comparison. The spike model was employed to deal with many zero WTP responses. The household average WTP was estimated as KRW 4,087 per year, securing statistical significance. The national value was KRW 84.1 billion per year. The preservation value of ZM estimated in this study can be used as important data for economic analysis of various projects or policy implementation for its preservation.

  • 본 연구는 국내에 벤처 창업 자금이 많이 제공되나 실제로 스타트업이 투자 유치에 어려움을 겪고 있는 초기투자의 딜레마 문제를 연구하였다. 기술기반 스타트업은 새로운 제품과 서비스를 제공하는 신규 시장을 형성하면서 일자리와 고부가가치를 창출한다는 점에서 국민경제에서 역할이 매우 중요하다. 하지만 주요 선진국에 비해 국내에서는 초기 스타트업이 기술이전 후 창업으로 연계되지 못하는 경우가 많은 실정이다. 특히 최근에 국내 벤처창업 생태계에 정부 자금의 공급이 넘쳐나고 있음에도 불구하고 초기 단계 기업들은 자금 투자의 필요성을 역설하고 다수가 자기자본으로 시작하고 있는 것이 현실이다. 이에 본 연구에서는 국내 창업벤처 및 육성 지원책을 고찰하고, 국내 벤처캐피털 투자현황을 분석하여, 초기 단계 벤처기업에 대한 투자 활성화를 위해 투자 방식의 개선, 투자 주체의 확대, 그리고 투자 유형의 다변화를 제시하고자 하였다. 또한 벤처생태계의 초기투자 활성화를 위한 정책 수립에 필요한 조사와 방안을 제시하였다.

  • The purpose of this study is to explore whether open spaces with land use characteristics of forest green areas can have different influence on the urban heat reduction depending on the location distribution, through the case of Gangneung-si downtown area. As a research method, the InVest Urban Cooling Model, which is a thermal phenomenon analysis model, is employed based on the most recent data available in 2018. In order to focus on the effect of location distribution of open space in the city, the downtown area is set as the observation area, not the entire city. The analysis of the land use location distribution scenarios shows that large-scale forests or clustered forests are more effective in reducing atmospheric heat in the region than several small-scale forests.

  • Unlike previous studies that dealt with the basic characteristic of My Data in terms of the legal system, this study analyzed the impact of the basic characteristic of My Data, which is finding a balance between the use and protection of personal data, on My Data services and government policies at home and abroad through a literature review to present implications for the creation of a healthy My Data ecosystem. The basic characteristic of My Data acted as facilitators and barriers for the acceptance and activation of My Data services, and suggested the values and directions pursued in the My Data policies of major countries. This suggests that a more balanced perspective is needed in promoting MyData services and government policies in the future. It is hoped that this study will contribute to creating a healthy ecosystem of MyData and promoting desirable government policies.

  • The purposes of this article are to criticize social services, and to consider alternative caring policies and social economic regime to cope with caring blank, in the view point of A. Gorz. According to Gorz, in the value of growth of capitalism, people who are in charge of household affairs and caring work make inroads into the wage market. At this point, as caring blank is occured, social services are emerged. These new aspects are 'Commodification and Rationalization of Private Life'. This article suggests alternative ideas to these aspects. First, universal care giver·breadwinner model, second, the dominance of eco-reason and shorter working hours.

  • While the expansion of protected areas in accordance with Korea's National Biodiversity Strategy contributions to the conservation of biological diversity, it incurs economic losses and poses threats to the livelihoods of local residents. Payment for ecosystem services (PES) compensates local residents for their economic damages in a sustainable manner. To assess feasibility of PES, there is a need to estimate the general public's benefits from biodiversity conservation in protected areas. This study attempted to estimate visitors' willingness to pay (WTP) for biodiversity conservation in Mt. Jiri using the contingent valuation method (CVM). The WTP of respondents for the expansion of protected areas to increase biodiversity conservation was estimated at 16,103 KRW per household per year and this equates to a total of 316.8 billion KRW for all the households in Korea. The higher a respondent's age, education level and household income level, the more willing he or she is to pay for biodiversity conservation. Likewise, respondents who are aware of Mt. Jiri's designation as an Ecosystem and Landscape Conservation Area are more willing to pay for biodiversity conservation. Moreover, the higher the importance placed on biodiversity conservation policy, the higher the willingness to pay for biodiversity conservation. To enhance the feasibility of PES schemes, it is necessary to improve the general public's knowledge and awareness of biodiversity by providing opportunities for education and more information on biodiversity and biodiversity policies.

  • A mixed farming system that includes organic rice production and freshwater fish farming is being called into attention in Korean agricultural industry and rural areas in order to improve farm management and environmental conservation. This study was conducted to evaluate the environmental and ecological value of such mixed farming practices. Expert assessment and rapid assessment method (RAM) of wetland evaluation were employed for this study. Experts have responded that biodiversity conservation including amphibian and reptile habitat (2.39), aquatic insect habitat (2.36), Fishery habitat (2.34), vegetation diversity (2.13), avian habitat (2.05), and experience and education were the most important function of mixed farming. The wetland function evaluation conducted using modified RAM indicated that rice-fish mixed system showed improvements in most of the evaluated functions, compared to the conventional rice paddies. The overall wetland function of rice paddies in rice-fish mixed system was greatly improved as compared with the conventional rice paddies. Rice paddies are known to play an important role in biodiversity maintenance, and provide ecosystem services such as climate modulation and carbon reduction. Rice-fish mixed system of farming may not only improve various ecosystem services of rice paddies, but may increase farm income through value added fish farming, as well as promotion of social services such as education and maintenance of tradition. Additional research is needed for quantitative analysis of the values gained from the most improved wetland function when mixed farming system is actually put into practice, and to utilize the results in advertising of the organic rice, and in various sectors such as food, education and direct payment policy.
