  • Trail and campground deteriorations and their environmental changes of soil and vegetation were studied in Tonghwa -Sa district of Mt. Palgong Natural Park through 1988 into 1989. The results are summarized as follows : 1. The bare width of trail as one of the trail condition factor was significantly greater on the more heavily used trail. Deterioration types of trail which had higher frequency for a total of 45 observations were rock exposure(42%), trail deepening(40%) and root exposure(18%) in the high order. And also sound type on which the trail was not deteriorated at all amounted to 33% of all observations. 2. Ecological changes of soil and vegatation of trailsides were not found at a uniform tendency except that soil hardness was slightly decreased from trail edge to the forest, but they could be grouped by the type of user\`s behavior and site conditions. Use impacts on the natural environment of trailside in Mt. Palgong are still far from the severe harmulness. 3. Worse damages to compground condition were appeared in Bawi-gol than Susu-gol campsite. Types of mechanically damaged trees were tree with exposed root(63% ), scared tree(43% ), mutilated tree(30 % ) and felled tree in highly frequent order. And diameter increments of trees in campsites were oppressed by the campers. 4. Tree damage types and their frequencies could be basic as a means of which grasp the bounds of user's impacts. User's disturbance on campsite extended to the distance of 70∼90m from the core of campsite at Pawi-gol and 20∼30m at Susu-gol respectively. As the tolerant trees to use impact, Lespedeza maximowiczii, Rhus trichocarpa, Acer palmatum, Rubus crataegifolius and Celastrus orbiculatus were considered.

  • Objectives : The objective of this study is to apply the contents of "WaHyul(訛穴 : The errors of acupoint locations"of "ChimGuKyungHumBang" to modern acupoint locations. Methods : The text of "WaHyul" was closely examined and analyzed. "WHO standard acupuncture point locations in the western pacific region" was reviewed based on its contents. Results : According to the analysis, the correct 少商(LU11) was mentioned as a spot appropriately distanced from the corner of the nail root under the skin. This is the most accurate and reasonable synthesis of other related texts. Furthermore, the necessity of defining the locations of all the well points was also emphasized and their locations were mentioned that could be located by the same method. There is no further discussion of other acupoints apart from descriptions of their locations from other texts. Some parts that were pointed out as common errors included not only commonly made mistakes, but errors made in acupuncture texts as were true for 神門(HT7) and 肩井(GB21). The standards of 少商(LU11), 合谷(LI4) and 足三里(ST36) presented in the WHO Standardization are not only similar to what 「WaHyul」 indicated as errors in acupoint locations, but also deviate other acupuncture texts; appropriate corrections must be made. The standard of 肩井(GB21) presents a new acupoint locating method never mentioned before in received classic acupuncture texts and so a rediscussion is in need. Other standards, such as the 絶骨(GB39), had some points of controversy, yet somewhat incomplete while HT7 did not go beyond the bounds of "WaHyul". Conclusions : "WaHyul" can be used to revise WHO standards, and has practical value in modern acupoint locating.
