  • This research was conducted to understand the extent to which visitors to the DMZ Pyeonghwa Nuri-gil Trail(located in one of the most Ecologically Sensitive Areas(ESA) of Korea) are motivated by perceived constraints and loyalty to the trail. Self-administered questionnaires were distributed to the participants of the '2010 DMZ Border Trekking Course', which resulted in collecting 317 valid responses. For statistical tests, the respondents were divided into three clusters(accidental, activity-driven, and nature-driven) by their motivation for the visit. ANOVA was conducted to examine if the three groups differ in terms of the perceived constraints and loyalty to the DMZ Pyeonghwa Nuri-gil Trail. The results showed that nature-driven visitors were more likely to perceive "psychological constraints" than accidental or activity-driven visitors. As for loyalty, accidental visitors displayed the lowest level of loyalty while nature-driven visitors indicated the highest level of loyalty. These results illustrate that nature-driven visitors not only have the strongest desire to experience and learn about ESAs but also possess the highest sense of loyalty to the trail. It can further be argued that nature-driven visitors are the ones with the greatest concern for the trail's well-being. The paper concludes with the contention that understanding the demand and characteristics of trail visitors is critical to the future development of the trail.

  • This study was conducted to investigate the herbicidal response and effective control strategy of sulfonylurea(SU)-resistant Scirpus juncoides Roxb. occurred in the paddy fields of Korea. A biotype of Scirpus juncoides Roxb. resistant to SU was identified in the paddy fields treated with SU herbicide-based mixtures for seven consecutive years. The apparent SU resistance observed in Scirpus juncoides Roxb. was completely confirmed in greenhouse tests. The susceptible biotype was almost controlled at the recommended dose of all the tested, but the resistant biotype was survived 20 to 30% even at 10 times higher dose of each the recommended dose of SU herbicides. The $GR_{50}$ values of 4 SU herbicides for the resistant biotype were 53 to 88 times higher than those for the susceptible biotype. The acetolactate synthase(ALS) isolated from the resistant biotype against bensulfuron-methyl and pyrazosulfuron-ethyl was less sensitive than that of the susceptible biotype. The $I_{50}$ values of the resistant biotype against bensulfuron-methyl and pyrazosulfuron-ethyl were 498 and 126 times higher than those for the susceptible biotype. A rapid diagnosis for identifying resistance of Scirpus juncoides Roxb. was possible within at least 3 days after SU herbicides. Three herbicides having different mode of action from SU herbicide, carfentrazone-ethyl, pyrazolate and simetryne exhibited excellent controlling effects on the resistant biotype of Scirpus juncoides Roxb. till 3.5 leaf stage. Among the SU-based herbicides, pyriminobac-methyl+pyrazosulfuroil-ethyl+carfentrazone-ethyl GR and azimsulfuron+carfentrazone-ethyl+pyriminobac-methyl GR were very effective to control resistant biotype of Scirpus juncoides Roxb. without rice injury. The resistant biotype which were not controlled with SU herbicise-based herbicides survived from the fields were effectively controlled by bentazone SL.

  • This study were carried out to establish the directions on ecoturism development in linking $rural\;{\cdot}\;mountain\;{\cdot}\;fishing$ villages together by led community dwellers for an alternative plan in order to economic active of $rural\;{\cdot}\;mountain\;{\cdot}\;fishing$ communities and reconstruction of community's cooperative organization and improvement and development of $rural\;{\cdot}\;mountain\;{\cdot}\;fishing$ village's domiciliative envirnment of Korea. The method of this research was chiefly used literature investigations and collections by field investigation in case of a few ecoturism resort of Korea. The result of this study were as follows : Ecoturism development in linking rural mountain fishing villages together by led community dwellers for an alternative plan in order to economic active of $rural\;{\cdot}\;mountain\;{\cdot}\;fishing$ communities and to reconstruct of community's cooperative organization and to improve and develope of $rural\;{\cdot}\;mountain\;{\cdot}\;fishing$ village's domiciliative envirnment of Korea will be effective to improve tourism environment. Especially, ecotoutism development will be effective and alternative plan in order to preserve $rural\;{\cdot}\;mountain\;{\cdot}\;fishing$ regions of our country's intact from the induction of act of pollution.
