The study was carried out to select natural environmental factors that affect damage to hiking paths and to provide directions for facility management of hiking paths by a logistic regression analysis. The study sites is a total of 123 sample sites that located in the Baekdudaegan Guropo-Gisaengnyeong hiking trails. The variables used in the analysis model included mountain trail damage, forest type, herb of soil and crown density obtained through a field survey and included slope, soil and rock exposure obtained through FGIS. A logistic regression analysis of 43 sites and 80 undeveloped sites, 4 elements were selected for slope, herb of soil, soil and rock exposure. The slope and the herb of soil were positively correlated and the exposure of rock was negative. Soil has shown a positive correlation with its low missile and high sand ratio Saturn. Therefore, the management of the mountain hiking paths facilities should be established and restored considering the slope, herb of soil, soil and rock exposure.

In image processing we encounter some tasks to detect ellipse or to discriminate the curves. LSM is well used to fit curves to ellipse but it can fail to fit correctly when fitting to defected one. To overcome this problem, we propose Modified LSM. Only 2-parameters among 5-paramaters are to be determined by LSM, while 3-parameters are to be calculated by the constrain that the curve must pass 3 given points. Those 3 points are selected by operator so as to have elliptic feature. Such proposed MLSM shows better result than genunal LSM in case when the ellipse is severely defected. and is proved to be good method for determing the human dentition.

본 연구에서는 Schwartz의 Norm Activation 이론을 도입하여, 실 외휴양지에서 환경훼손행위 관리를 위한 Communicatin 정책의 이론적 배 경으로 도입되어 있는 Prosocial Behavior 이론의 적용성을 실험하였다. 본 연구는 실험실에서 자체개발한 설문지를 통하여 수행되었으며, 미국 Texas A&M 대학교의 남녀 대학생 340명이 참가하였다. 본 실험의 결과 실외휴 양 환경에 대한 훼손행위(Depreciative Behavior)의 인과응보적인 결과를 알려 주는 Information이 실외휴양지 관리에 바람직한 행동의사를 활성화 시키는데 효과적인 반면, 훼손행위에 대한 법적인 제재조치를 설명하는 위 협적 Information은 바람직한 행동의지를 활성화시키지는 못했다. 이용자의 개인적인 성향인자인 사회적 책임감(Social Responsibility)의 고저는 사회 에 바람직한 행동의지의 활성화와 직접적인 관계가 있었다. 그러나, 사회적 책임감의 고저가 환경훼손행위에 대한 인과응보적인 Information이나 제재 조치에 대한 위협적인 Information과의 교호작용은 없었다. 통계학적으로 유의성은 적으나 사회적 책임감이 높은 시험구의 경우 제재조치에 대한 위 협적인 Information에 대한 반작용이 컸으나, 사회적인 책임감이 높은 실험 구의 경우 제재조치에 대한 위협적인 Information이 효과적인 결과를 볼 때, 이용자의 바람직한 행동의지에 역으로 작용하는 Communication정책에 대한 체계적인 연구가 요구된다.

This study is for the preservation plan of the tradition space which is performed by the damage status analysis through performing the value assessment. Especially, it is an experimental study for finding the process and methods by analyzing the major element for the value assessment of the selected object's damage status through the expert group who are systematized in their interest to conserve the traditional structure in traditional space. For that purpose, this study should be performed by the fundamental understanding of the physical property of the Supyo-bridge and the condition of the selected site's environment. Meanwhile, this study has been done that 'map of the damage status distribution' for making records of damage status of the Supyo-bridge on the property utilized field measurement adapted by photogrammetry and assessment guidelines, which are for investigation on damage status of objects that are standardized 'Raccomandazioni Normal' which could be said construction culture assets management guidelines of Italian government. As the result of investigation, damage status of each part in the Supyo-bridge was mostly composed of damage by sediment and corrosion and in case of 9 damage types including corrosion, in consideration of physical and chemical properties and distribution status of those elements, it is made an judgement that is not working as a threatened factor regarding security of the Supyo-bridge. On the contrary, for the improvement landscape, in case of 'Thermoclastism' phenomenon observed in 'upper floor', 'Myungae stone' and 'bridge pier' is that when taking it into consideration that is widely distributed concentrated on the bridge pier, surface reinforcement job along with elimination of damage part will be judged to be requested for earliest treatment.

For understanding the tourists' characteristics of several types of ecotourism sites, we surveyed and analyzed the demographic characteristics, travel motivations and cognition of damage in Bukhansan trail, Upo marshes, Jirisan trail and Uljin Keumgang pine tree trail. The field survey were conducted through face-to-face interviews. In the case of Bukhansan trail, many people came to build up their health, so the ratio of eco-tourists and the awareness of environmental damage was low. In Upo marshes, there were many group tourists who want to enhance friendship between the colleagues. And the ratio of eco-tourists, enjoying several activities such as observation or experience about the ecosystems of wetland and bird watching appeared high, but the cognition of tourists about the damage of natural environment was low because the flatland type tour site, Upo marshes has less damage factors comparing with mountain type tour sites. In Jirisan trail, eco-tourists, nature tourists and mass tourists appeared mixed and the cognition of damage was higher than that of flatland type. In the case of Uljin Keumgang pine tree trail, almost indices showed higher values than other sites because the tourists who visited there have high cognition of eco-tourism and nature conservation by limiting entrance. Tourists were generally accepted positively the control method such as collection of entrance fee and visitor reservation system when natural damages are expected.
