Forest lodge are divided into forest resources, auxiliary facilities, and users, and are constantly being used along with well-being culture. In addition, attention to the safety of users is also required, and this study aims to study how users evacuate within a short time (golden time) in situations of natural disasters that may occur in forests. In order to search for the current location of the user and find the best evacuation route, 3D scans of the entire forest lodge(forest resources, auxiliary facilities, etc.) are performed, and the optimal trajectory to the evacuation site is found through recognition of the current location. It is believed that it is possible to provide a quick evacuation guide through a mobile device with gps.

Phytoncide, which is emitted from plant against the insect species and bacterium, has been known as a health builder for human. Monoterpenes are major components of phytoncide. This study was conducted to investigate the distribution characteristics of phytoncide(monoterpene) depending on main species of tree, season, and meteorological factors in the 5 recreation forests, Chungbuk area. From the result of the study. it was shown that the annual concentrations of monoterpene are ranged in 236.0pptv - 698.3pptv depending on main species of tree. The variation of seasonal concentration was summer > spring > fall. The monoterpene concentration of coniferous forest was founded to be higher than broad leaved forest. In general, concentration of major components is ${\alpha}$-pinene > ${\beta}$-pinene > camphene > d-limonene. The concentration of terpene was founded to be greatly influenced by the meteological factors such as insolation and temperature.
