This study investigated the characteristics of variations in carbon dioxide concentration and air temperature with the vertical change of surface in a grassplot. Field observations were carried out at a grassplot in Gyeongnam Science High School, over four days in August and November, 2015. Continuous observation equipment (GMP343, VAISALA) was installed at the LP (0.1 m from the surface) and UP (1.1 m from the surface) points, and the carbon dioxide concentration and air temperature were measured simultaneously at 1-min intervals. To summarize the results of the observation, August had higher than average concentrations of carbon dioxide, while November showed average air temperatures. Moreover, the concentration of carbon dioxide was higher at the UP point, while the air temperature was higher at the LP point. The correlation coefficient of carbon dioxide concentration between the UP and LP points was 0.80 in August across all the four days, while it was higher in November at 0.58 0.95. The results of the regression analysis of carbon dioxide concentration with air temperature changes for both August and November showed a distinct change at the LP point (R2=0.36 0.76), as compared to the UP point (R2=0.1 0.57). Between the UP and LP points, the carbon dioxide concentration and air temperature regression analysis results indicated that an active exchange was taking place between the two points.

This is a comparative study focused on the scenic landscape preferences derived from visitors's perceptions at the Dulle-gil and the uphill trail in Bukhansan National Park. Unlike previous landscape assessment methods, this study contains more direct and on-site analysis with methods of understanding the visitors’ perceptions by using ‘visitor employed photography(VEP)’ which requires each visitor to take preferable scenic landscape with one’s own smart phone camera. The scenic landscape types at two different trails were categorized and then the types favoring most of participants were verified. There are total number of 16 visual landscape types preferred by participants at both the Dulle-gil and the uphill trail in Bukhansan National Park. As in terms of consensus photography(CP) on the Dulle-gil was found to have more diverse elements including both natural and artificial elements compare to the uphill trail. Furthermore, the perceptually excited node(PEN) at the Dulle-gill were found to be more scattered evenly whereas PEN at the uphill trail were concentrated on the entrance and the top of the mountain. It is necessary to consider that the scenic landscape management at the Dulle-gil and the uphill trail require different approaches. Facilities were set based on careful consideration of distinctive geographical features and vegetation in the Dulle-gil. And the management need to be focus on the 'forested area' maintaining natural state in the uphill trail. Futhermore, the result of the CP and PEN in the trails would be helpful to proceed the next step of landscape perception study depending on characteristics of groups.

Lactic acid bacteria (LAB) are industrially important microorganisms for probiotics. The recent widespread application of LAB for preparation of functional food is attributable to the accumulating scientific evidence showing their beneficial effects on human health. In this study, we isolated and characterized plant-derived LAB that show angiotensin-converting enzyme (ACE) inhibitory and antioxidant activities. The selected strain K2 was isolated from Kimchi, and identified as Lactobacillus plantarum by 16S rRNA gene analysis. The strain grew under static and shaking culture systems. They were also able to grow in different culture conditions like 25℃∼37℃ temperature, 4∼10 pH range and ∼6% NaCl concentration. L. plantarum K2 was highly resistant to acid stress; survival rate of the strain at pH 2.5 and 3 were 80% and 91.6%, respectively. The strain K2 also showed high bile resistance to 0.3% bile bovine and 0.3% bile extract with more than 74% of survival rate. The cell grown on MRS agar plate containing bile extract formed opaque precipitate zones around the colonies, indicating they have bile salt hydrolase activity. The strain showed an inhibitory activity against pathogenic bacteria such as Escherichia coli, Staphylococcus aureus and Listeria monocytogenes; antibacterial activity was probably due to the lactic acid. The K2 strain showed relatively higher autoaggregation values, antihypertensive and antioxidant activities. These results suggest that L. plantarum K2 could be not only applied as a pharmabiotic for human health but also is also starter culture applicable to fermentative products.

From 1970, the concept of ecotourism is introduced, lots of studies in ecotourism appeared. Review these studies are necessary for future ecotourism studies. Some review studies on ecotourism are existed. However, these approach also limitation of subjectivities and some sorts of papers has not been reviewed. This study use keyword network analysis which is used as big data analysis to overcome the limitation. Foreign 2455 studies and domestic 163 studies which have ecotoursim in keywords, are analyzed for reviewing. As a result, 3 cluster(‘Sustainable tourism development’, ‘Ecological conservation’, ‘Ecotourist analysis’ appeared, in ecotourism studies. In addition, this cluster has deep relationship with region. ‘Sustainable tourism development’ is related to Eurasia, Australia, Europe. ‘Ecological conservation’ is related to Africa. ‘Ecotourism analysis’ is related to North America. Especially ‘Resident participation’, ‘Stakeholder’ are appeared many times in Asia region. These results show that ecotourism studies are interpreted in regional contexts. It means that although only one word ‘ecotourism’ is used in different contexts, regional approach are needed for exact use. In Korea, the keywords are focused on ecotourists and developments. As Korea has lots of ecotour village, resident participation studies have to be supplemented.

In existing method, research for landscape resource is driven by professional (or with the participation of local people at Tokenism level), and usually hinder local residents from reflecting their appreciations on the landscape resources in their own ways and eventually ends up with indistinguishable landscape planning. To avoid this, a profound understanding of what landscape they experience in their daily life and how they perceive it should be empirically analysed carefully. The purpose of this study is to apply walking behavior as a method to examine local residents’ subjective perceptions and consider its usability. The researcher walked the site(Sucheongri) with the residents, carrying a GPS device, taking photographs of the landscape objects they described, and recording the relevant explanations. After gathering photographs and explanations which represent the research participants’ individual subjective perception, the researcher analysed the explanation using open coding, based on grounded theory. By the analysis, 117 landscape objectives are identified and 18 reason factors for landscape perception were deduced from the explanation. Those factors could be classified as ‘positive feeling inducing’ and ‘negative feeling inducing’, and also as ‘personal emotion based’ and ‘community based emotion’. By comparison between feeling map by conventional method and feeing map by new method, usability of new method was empirically reveled. Walking behavior makes it easier for researcher to get more abundant data in quantitative aspect and profound understanding with affection of respondent by allowing them to ‘go beyond’ the perceptions they remember. Finally new method with walking gives professionals a contextual understanding of a place and more resident-oriented plans and management on sites.

Korean sixth industrialization policy is similar to that of Japanese such as goal of policy, setup and promotion method of specific policy projects as it benchmarked a Japanese case. First of all, the certification systems of both countries, the most representative policy, are very alike that the governments officially certificate management bodies, prepare the ground for continuous sixth industrialization, devide intermediate support organization into the central unit and regional unit, and have the function of support and control of sixth industrialization management bodies. Furthermore, both countries create fund for sixth industrialization as an investment support policy, and push forward with the phased support policy businesses such as individual support and connected support for management bodies. However, there are some differences between certification systems of both countries such as process-oriented or result-oriented for certification, subtle differences of the role in support organization, and the range and rate of support.

The necessity of universal design for forestry is increasing. Although several studies applied universal design in forest site, they had been only concentrated on the barrier-free design for the limited activities rather than overall utilization for considering all visitors from the disabled, the elderly and the infirm to the baby and child. The purpose of this study is to find out the principle of the universal design within forest welfare service facilities by analysing how socially disadvantaged people perceive overall usage of natural recreation forest area. This study figures out the main principles of universal design in forest welfare through analyzing usage of children and disabilities in Yumyeongsan natural recreation forest where is one of the popular type of forest welfare area. By doing focus interviews targeted on children and disabilities, the results are analyzed through semantic network analysis, objectively. The result proves that universal design in forest welfare area contains four principles; convenience, safety, diversity and amenity. Also it confirmed that disabilities need better internal space facilities and priority care. Through those characters of universal design, forest area will be able to cover more various type of users as forest welfare area.

In analyzing the issues of ecotourism, collecting opinions of local residents and participants is an essential process because ecotourism needs to keep ecological sensitivity and respect local residents' ecological lives. Thus, the objective of this study is to analyze the local participants' attitude in resident-oriented ecotourism. Maha ecotourism site, as a study site, is located in Pyeongchang-gun, one of the twelve ecotourism sites designated by the Ministry of Environment. This site has drawn attention since the local government of Pyeongchang-gun transferred its management right on Maha ecotourism sit to the organization of local residents in 2013. This study uses Q methodology which is the most popular research method in analyzing people's subjectivity, that is, viewpoint and attitude. This study have found that there are four features in the subjectivities of participants toward ecotourism site: first group is the people who want more autonomous management right of local residents on Maha ecotourism site. Second group is the people who only want to stand by the ecotourism management. Third group is the people who focus on the migration of talented persons into their neighborhood owing to the program. Lastly, fourth group is the people who focus on the quality of the ecotourism program. In case of the second group, though they have negative opinions of the program, they have much interest in successful cases in other countries managed similar programs with Maha ecotourism. It would be effective for the group to have opportunities to experience successful ecotourism cases in other countries. On top of it, having seminars regarding ecotourism or holding community councils frequently would be very helpful for encouraging the second group of people to join in the ecotourism program actively like other groups of people. Supplying more manpower and developing various programs are also necessary in order to support other three groups.

Ecotourism has the potential to boost the energy of a village as it pays keen attention to the ecosystem and the residents of the village. It is empowered by participation of and cooperation among stakeholders who are closely involved in ecotourism. However, many of them express difficulty in striking a right balance between development and conservation with regard to promoting ecotourism. Against this backdrop, this research paper investigates the structure of conflict that the stakeholders, especially those in Stork Village in Yesan County, South Chungcheong Province of Korea, experience during the process of establishment of government-led ecotourism. In addition, this study examines the problems of government-led ecotourism model and how they can be addressed. To analyze conflict structure, this paper used Q methods and found out that the budget-related stakeholders are largely divided into four groups as who; a) complain about how business profits are distributed; b) secure profits by expanding programs; c) consider human settlement, and; d) broaden people's participation. The biggest contributor to the conflicts is found that compensation was given discriminately to different jurisdictions. The second finding is that residents became less cooperative when the financial compensation did not live up to their expectation. For instance, they would demand the tourism facility physically expanded, repeatedly complain about the process of the work, and even accuse the government of degrading ecosystem. In other words, unless the compromise is reached with the residents regarding financial compensation, it could be difficult to encourage their participation and develop as a program-oriented tour. Lastly, the tour program needs to induce voluntary participation of the residents and deliver proper information on ecosystem and natural resources so as to last as sustainable ecotourism. The success of ecotourism will be subject to the cooperation of stakeholders in a region, conservation of our fragile ecosystem, and realization of sustainable growth through sharing economic benefits. This study looks into the cause of the conflicts of ecotourism sites and their structure. If this paper can bring about cooperation of stakeholders, the management and operation of ecotourism sites would be more sustainable.

This study has analyzed overseas projects of building rural communities using vacant houses. It is aimed at identifying the roles of NPO in the community-building projects and providing implications applicable to Korea. In recent years, there has been a spike in the number of vacant houses in rural areas. It is due to rapid urbanization and uneven distribution of the population across the country. Those are the reasons that prompted community-building projects. To solve the vacant house issue, there has been rising interest in building communities through vacant houses as rural resources and effectively integrating them as useful resources. However, the roles of key entity that pursues community-building projects using vacant houses have not been discussed sufficiently. Thus, this study deals with the 'Vacant House Recreation Project of NPO Corporation in Onomichi' in Hiroshima, Japan. Through the case study, the following are introduced as NPO's roles in community-building projects using vacant houses. First, pursuing promotion and attracting attention by making the utilization of vacant houses sensational; system improvement; offering information. Second, enhancing the perception of local residents by offering local services using vacant houses; offering community-building items. Third, forming a place of public discussion to solve conflicts during community-building projects using vacant houses; offering alternatives to building communities. Above all, such roles have led to the key status of NPO during its community-building projects using vacant houses. It offers the following implication for Korea: Future vacant house-related policies for rural revitalization should be done from community-building standpoint and include establishing the roles of NPO.

For the purpose of drawing a representative type of utilizing idle farmlands, this study collected and analyzed newspaper articles about cases of utilizing idle farmlands in the past decade using Internet search engines. Prior to this, it clarified a concept of idle farmlands to raise accuracy of searching articles, and selected NAVER as a search engine. It set "idle farmland", "abandoned land", and "utilizing" as basic search words in search option, and also set search period from 1st of January in 2004 to 31st of December in 2013. This study primarily searched 1,593 articles, and extracted 165 articles excluding overlapped and unrelated articles. Furthermore, it investigated extracted articles by date, media, headline, content of use, region(province), particular area(city and country), main agent, item and keyword 1, 2, 3 for proper use. This study also examined frequencies by year according to indoor and outdoor environment as well as regional differences through frequencies by regional groups and chronology. Furthermore, it drew a diagram of frequency flow of keyword 2, 3 with each keyword 1 as the central figure in order to draw various types of using idle farmlands. Through the diagrams, this study drew 9 using types such as (1) community service. agriculture type, (2) high income. agriculture type, (3) sightseeing. landscape. agriculture type, (4) livestock. agriculture type, (5) weekend farm type, (6) high income. woodland type, (7) ecology. landscape. woodland type, (8) agricultural work-study type, (9) ecological environment type.

The purpose of the present study is to examine the characteristics of intermediary organizations for rural tourism by analyzing how they are run, especially in Yangpyeong-gun and Icheon-si Nadri groups, and to further look for the desirable role they should play. Since the activities of these intermediary groups have not been accumulated enough to be able to be used for a study, grounded theory was adopted as deemed appropriate among other qualitative research approaches for this paper. Three main findings of the current research are as follows. First, the rural tourism intermediary organizations have characteristics that are leaning towards local villages more than visitors, although they are in the middle of a spectrum stretching between 'visitors to the green villages' on one end and the 'green villages' on the other end. Second, the intermediary groups work not just as a bridge among different green villages but also as a mediator, facilitator and a guide, noting that such roles can vary significantly depending on the level of competence of the groups themselves and the extent to which the government steps in. Third, the tourism intermediary organizations can contribute to local community-building, going beyond the boundaries of green village. They help to improve the quality of tour experience which leads to revitalization of local economy, and during the course of operating the intermediary groups, the community in the village can set up rules and resolve disputes and conflicts. Thus, the activities of the groups have the potential to create a local community by affecting not just at a village level but to a broader area where their operation is based on. Implications of this study are suggested in three ways. First, the paper looked at the interaction between rural tourism intermediary organizations and stakeholder in a comprehensive way with a qualitative research approach taken. Second, it identified the role and tasks of rural tourism intermediary organizations. Third, it is important to ensure that the tourism intermediary organizations play the local community-oriented role.

Self-sufficiency rate of food in South Korea is almost at the lowest level among OECD countries, and the decrease tend of farmland is expected to be continued. In this situation, the government has been revised the target self-sufficiency rate of food, and carried forward various policies in order to achieve it. One of those policies is the restoration business of idle farmland which is planned to carry forward after 2015. This study set up indicators evaluating effective use of idle farmland, and tried to apply in the field before carrying forward restoration business. The result of this study may be summarized as follows. First of all, it reset an evaluation indicator that was based on the evaluation indicator developed in order to set application directions of idle farmland. Next, it selected 30 idle farmlands with reset evaluation indicator among 11,635 which were inspected nationwide in 2012. Before applying indicator, it measured the condition of recycling such as accessibility of farmland, condition of irrigation and drainage system, land state, and surroundings by field investigation. Then, it calculated composite score in each target area through applying indicators, and verified the indicator by comparing calculated result with the one which was decided from field investigation. Finally, it carried out field investigation, correct and upgrade some problems of the standard of score calculation that was found during applying previously set evaluation indicator to target area, and established the final standard of calculation for evaluation indicator.

This study intended for Cheongryongsan Community Garden in Gwanak-gu, one of the demonstration places for 'Community Garden' Project recently implemented by the Seoul Government. This study had two major purposes: investigating the current status of the management and usage and identifying its characteristics; investigating users' awareness to consider the construction and operation directions of sustainable community gardens. This study was conducted based on several surveys such as an investigation into the spatial configuration and the management system of parks through a field study, a use survey through a questionnaire survey for vegetable garden users and an awareness survey about the construction direction of gardens direction preferred by users through the analytical hierarchy process (AHP). As a result of a questionnaire survey for vegetable garden users, the usage status was summarized as follows: Considering the common trends in the 2012 and the 2013 user survey, women used Cheongryongsan Vegetable Garden more than men. Over fifties used it most of all users. Users were mostly neighborhood residents. They used to visit there three to five times a week and stayed for about 30 minutes to one hour. Users differently responded to the question related to the order of priority for the use of the garden in the 2012 and the 2013 survey. They had increasingly used it for individuals' production activities more than social exchanges. As a result of making an AHP analysis for general park users, vegetable garden users there were clear differences in the targets which each subject put emphasis on in relation to the construction and operation of vegetable gardens. General park users recognized a vegetable garden as a park where park functions and the functions of the vegetable garden coexisted. On the other hand, vegetable garden users viewed it as a space where they attached importance to the functions of the vegetable garden like an allotment. Last, this study contemplated subjects related to the construction and operation of vegetable gardens which had to be considered in the future. Vegetable gardens tended to be biased as personal hobby places. It was viewed that the main reason was insufficient support activities for vegetable garden education and exchange programs originally planned when vegetable gardens had been constructed. Vegetable garden users recognized vegetable gardens as places for individuals' farming activities like allotments. For the desirable operation of vegetable gardens, it would be necessary to give priority to the park management before the production activities in individuals' vegetable gardens. The important role of the government would be to build the base through the provision of education and opportunities so that a local resident organization could actively participate in the management of a vegetable garden after a vegetable garden was constructed. It would be necessary to make a use survey and an awareness survey for users conducted in this study on a regular basis because the surveys could be important basic data in the decision-making process for the sustainable operations of the vegetable garden.

The purpose of this study is to identify effect in how urban garden is run by different operators in Korea, and consequently how it determines the level of community formation among urban garden users. Based on this analysis, the study is intended to present some points as to how to better manage urban garden. The operators are divided into three types: public, public-private partnership and private. The study interviewed each operating entity and surveyed garden users to gauge the extent to which communities are developed. After the ANOVA analysis and Scheffe post-hoc analysis, it was found that the levels of community formation among users of public and public-private partnership urban gardens were similar (so can be grouped together), whereas that of private urban garden users was higher (separated as another group). However, this study found no meaningful differences in the level of community formation among all types of urban garden in a local community. Some key suggestions are made as a result. First, as for the public and public-private partnership types of urban garden, it is necessary to foster leaders to build a community. Next, it is worth noting the potential of public-private partnership in realizing community revival through urban garden. The last suggestion is that, generally, the urban garden has only little influence on community formation in a local area so far, thus more practical consideration needs to be given to enhance the role of urban garden in a local community.

The purpose of this study is to identify characteristics of the landscape changes in Gwangjyu city and Icheon city, the suburban areas on the outskirts of the Seoul metropolitan area, by focusing on the causes of the urban sprawl and the resultant morphological characteristics of landscape degradation. Particular attention has been given to the ‘advantages for developing suburb including geographical proximity and land price’, ‘institutional regulation such as land-use regulation’ and ‘community solidarity’ as drivers for possible introduction of external factors. The types of landscape change were divided into three, after having on-the-ground research on eleven chosen towns and interviews with head of a village: Overwhelming Change, Separated and Small-Scale Change. It was found that, in general, the quality of landscape was best for the small-scale change type, followed by separated and overwhelming change types. While the types of landscape change are correlated with the geographical proximity, its relevance with land regulation is relatively weak. The study found that imposing a land-use regulation as a means to prevent changes in suburban village landscape may not be fully effective. Also it analyzed that villages could better manage with keen interest the surrounding landscape if there is a high degree of solidarity within the village community. Therefore, the sense of community could play an important complementary role to land-use regulation which does not suffice in itself to manage suburban landscape.

This study intended to suggest Voluntourism as a solution for alternative rural tourism for regional activation. Voluntourism is a form of alternative tourism on values of variety of tourism demand from pleasure to virtue. This study analyzed actual state of WWOOF(World-Wide Opportunities on Organic Farms) activities being operated in Korean rural village, one of representative of Voluntourism. Study aimed to explore the possibility of WWOOF activity as one of model of alternative rural tourism. We apply grounded theory method one of qualitative study methods for analysis of WWOOF Activities because WWOOF is still small activity in Korea. In result, we figure out the actual condition of WWOOF Korea activities as a vouluntourism through paradigm model of host and guest who had experience in WWOOF Korea. WWOOF activity is in its early stage so there many tasks. We suggested ideas for improving WWOOF activities to be one of new rural tourism business.
