  • The purpose of this study was to provide basic visitor and trail use data for developing trail management strategies in Korean national park system. To accomplish the purpose of the study, a questionnaire survey was carried on at two different national parks(Bukhansan and Chiaksan National Park). As for the results, root and rock exposure on the trails and trail width expansion were perceived as major types of trail impact. In addition, majority of respondents pointed to construct or maintain facilities on steep paths and repair trail surface as for the priority of trail maintenance. In conclusion, the priority of trail management and maintenance has to be differently determined based on each trail conditions because visitor impacts on the trails vary along with site-specific and activity-specific differences. Findings of the study expect to be used as fundamentals in trail management strategy making for Korean national parks.

  • TNF-related apoptosis-inducing ligand (TRAIL) is a promising agent for management of cancer because of its selective cytotoxicity to cancer cells. However, some cancer cells have resistance to TRAIL. Accordingly, novel treatment strategies are required to overcome TRAIL resistance. Here, we examined the synergistic apoptotic effect of apigenin in combination with TRAIL in Huh-7 cells. We found that combined treatment of TRAIL and apigenin markedly inhibited Huh-7 cell growth compared to either agent alone by inducing apoptosis. Combined treatment with apigenin and TRAIL induced chromatin condensation and the cleavage of poly (ADP-ribose) polymerase (PARP). In addition, enhanced apoptosis by TRAIL/apigenin combination was quantified by annexin V/PI flow cytometry analysis. Western blot analysis suggested that apigenin sensitizes cells to TRAIL-induced apoptosis by activating both intrinsic and extrinsic apoptotic pathway-related caspases. The augmented apoptotic effect by TRAIL/apigenin combination was accompanied by triggering mitochondria-dependent signaling pathway, as indicated by Bax/Bcl-2 ratio up-regulation. Our results demonstrate that combination of TRAIL and apigenin facilitates apoptosis in Huh-7 cells.

  • This study concentrates on the trail of the CNU(Chungnam National University) forest. The amount of use and the pattern of damage are considered, as well as the extent of environmental damage. Finally, some managerial strategies are proposed in connection with sustainable maintenance. The trail of the university forest is composed of three sections; one is the neighborhood park and the Institute of Information Technology/Communications, the second is the Institute of Information Technology/Communications and the Dormitory, and the third section is the Dormitory and the Foreign prof's Apt. The total length of the trail is 2.6km. The daily amount of use is 1,269 visitors per day. The amount of using increased three times the amount of that in 1998. This study shows the pattern of damage of the trail in the order of root-exposure, widening, rock-exposure, deepening and the divergence in the frequency of occurrence of all these factors. Environmental damage is also graded thus: grade 3 is 27.4m, grade 4 is 0.8m, grade 5 is 1.5m, and grade 6 is 0.2m. Accordingly, some managerial strategies were proposed in connection with the sustainable trail maintenance.

  • They are raising the necessity to prepare the conservational management strategy for the trail on the ridge of the Baekdudaegan where deterioration of natural environment along the trail as the rapid increase of visitors to the Baekdudaegan. The purpose of this study, followed after the Kwon and Lee(2003), is to research the deterioration condition of the trail between Namdeogyusan and Sosagogae on the Baekdudaegan. To accomplish the purpose, not only trail condition such as altitude, entire width, bare width, maximum depth and slope of trail, but also deterioration types of trail were surveyed at the total 182 points for 32.3km in length. Furthermore, impact rating class, which could be effective means to check the step and extent of deterioration process, was judged on each points of trail. Results informs us that the deterioration condition of the trail between Namdeogyusan and Sosagogae is not reached the level of grave concern yet, but some points and sections of trail are in urgent need of the integrated and organized maintenance. And some managerial strategies of trail were proposed in connection with the maintenance for trail on the Baekdudaegan ridge.

  • Visitor Impact Management (VIM) framework was developed in the United States to help recreation resources management to be more systematic and effective. It consists of a series of steps from examining problems and their causes to planning and implementing management strategies in order to solve the problems. This study was conducted to find management problems in Moodeung-san Provincial Park and suggest some alternatives based on VIM framework. Data were collected by on-site survey and a mail-back questionnaire in August of 1996 in Moodeung-san Provincial Park. Out of 1173, 519 respondents (44.2%) were used for the study. According to the study results, there were differences between users' perceptions about the present use of the park and the users' personal norms about the use of the park. That is, while 46% of the respondents considered the park should be used as 'the place for calm and meditiation,' only 19% of the respondents considered the park had been used as 'the place for calm and meditation.' Three social indicators (the number of users, the number of seeing others' inconsiderate behaviors, and the crime) and four ecological indicators (littering, human waste, trail conditions, and water quality of Moodeung-san valleys) were selected for the major managerial indicators of the study area. Generally, five out of 7 selected indicators were in worse conditions than the evaluative standards, Five indicators which were evaluated as in worse conditions include two social indicators (the number of users and the number of seeing others' inconsiderate behaviors) and three ecological indicators (littering, human waste and trail conditions). Two other indicators such as water quality of Moodeung-san valley and the crime were identified to be important for users' recreational experience. More concerns and systematic investigations on these indicators are needed. This study discussed some management strategies to solve the identified problems, and introduced how mangers may make use of these information for recreation resource menagement in the park.

  • The purpose of this study was to understand Jirisan-round Trail trekkers' socioeconomic and travel characteristics, travel motivations, and travel attitudes. On-site and email surveys were carried out from July to November of 2008 and a total of 1,026 individuals' data were analyzed. Survey results showed that the percentages of middle age users, highly educated, and professionals/managers were relatively higher among trekkers of Jirisan-round Trail. And they traveled with a small group, collected destination-related information before traveling, and showed a high level of satisfaction. Especially they had not only strong motivations for admiring, understanding, and experiencing the nature but also positive travel attitudes. Based on the results of a cluster analysis, the trekkers of Jirisan-round Trail were divided into two groups, ecotourists and nature tourists. The ecotourists group showed relatively enthusiastic participation, more nature-oriented and culturally sensitive travel attitudes, and a higher satisfaction. The results would be used for establishing effective management strategies for building environmentally and socially responsible trekking culture.

  • Damage to natural resources from inappropriate visitor behavior is a problem faced by National Park management. Based on the data gathered by personal interview and mail questionnaire, this study examines the effects of communication strategies to reduce depreciative behavior in Carlsbad Caverns National Park. One-quarter of Carlsbad Caverns visitors indicates that they have noticed damage to cave formation during their tour. Almost 38% of visitors say that they have witnessed someone touch a formation inside the Caverns. This is a relatively high percentage compared with other depreciative behavior research to refrain from "tattling" on fellow visitors. Two-thirds of the respondents recalls touching formation replicas before entering the Cavern, while almost all visitors (97.9%) say that they have heard the ranger's talk about not touching formation or leaving the trail. Visitors feel that the ranger's talk is more effective in reducing depreciative behavior than the formation replicas, although at least three-fourths of all respondents believes both techniques are effective.

  • This study applied the normative approach to establish evaluative standards for the facilities in Moodeung-san Provincial Park. Based on the established evaluative standards, this study examined the present facility managerial conditions of the park, and suggested some management alternatives to solve the identified problems. Data were collected by on-site survey and a mail-back questionnaire during August of 1996 in Moodeung-san Provincial Park. Out of 1,173, 519 respondents (44.2%) were used for the analysis. According to the results, three indicators out of five established indicators except 'adequacy of garbage cans' and 'adequacy of trail-guidance facilities' were in worse conditions than the established evaluative standards. The three indicators were 1) adequacy of toilets, 2) cleanness of toilets, 3) waiting time for using public transportations. The present condition for 'adequacy of trail-guidance facilities' was the same with the evaluative standard. This study suggested some management strategies to improve these problematic conditions, and introduced how managers may use these information for the facility management of the park.

  • Understanding of the reasons why users in recreation settings select particular trails may provide useful information for effective recreation resources management. This study investigated the present use of the major trails in Mudeung-san Provincial Park and the major influential factors on trail selection. This study was conducted in Mudeung-san Provincial Park stretching over Hwasun-gun and Damyang-gun of Chonnam Province and Kwang-ju city during August in 1996. Data were collected through on-site survey and mail-back questionnaire. 519(44.2%) out of 1173 survey samples were used for analysis. Reasons for selecting a particular trail were classified into 8 major factors. In overall, the order of the importance degree of the factors was 1) aesthetics of landscape, 2) safety(from physical and crime), 3) conditions for health, 4) quietness, 5) familiarity, 6) on the way to the destination, 7) convenience/social, 8) others' intention. There were differences in the degree of importance of each factor depending on trails, users' characteristics(eg., gender, age, group size, visit experience, etc.) and users' behavioral patterns. Recreation motivations were classified into 5 major factors. The order of the importance degree of the factors was 1) contacting with nature, 2) self-training, 3) solitude, 4) social interaction, 5) appreciating cultural properties. Regardless of trails, 'contacting with nature' was the most important factor, and the degree of importance in the other 4 motivational factors showed only a little differences in order according to the trails. There were correlations between major factors for trail selection and recreation motivations. The results of this study may provide foundational information for establishing effective management strategies through better understanding of the present use of trails and influential factors on trail selection. It can be used for reducing the present social and ecological problems caused by use concentration on certain trails and providing users with better quality of diverse recreational experiences. This study discussed the findings, and suggested some management strategies based on these information.
