This study was conducted to investigate seasonal avifauna and to suggest a proper way how to manage and protect wild birds in Chirisan National Park. The survey was carried over 3 main trail districts by line transect method to figure out influence factor of inhabitation of wild birds from February to November in 1991. The study results are as follows : The observed birds were belong to 6 orders 24 families 49 species and 981 individuals and Falco tinnunculus(Natural monument No. 323). These birds also classified into 24 species for residents, 12 species for summer visitor. 9 species for winter visitor, 4 species for passage migrant, respectively. The observed average frequeney of birds was 2.09e.a./ha, and main dominant species were Parus varius, Parus major, Emberiza elegans, Garrolus glandarius, Sitta europaea, Hypsipetes amaurotis, Parus palustris in order. Cheoneun-sa trail route showed relatively decreasing trend of wild birds during spring and fall season because of the highest trail use of visitors. Maximum frequency of species and individuals appeared at Hwaum-sa route in spring and at Piagol route in fall. respectively. Those regions well explained the advantageous inhabitation area of birds in both regions. The diversity index of birds in winter showed little difference of similarity index due to balanced use of trails. Seasonal low similarity index in those 3 main trail district indicate a dissimilarity of environmental factors. Trail use restriction as a provision of proper management and protection of wild birds have to be made at Hwaum-sa route where propagation of birds actively occurred in spring and at Piagol route where birds wintering were observed will contribute to enhance species diversity in the future.

This study discusses developing historical trails and ecological trails in rural area. Since the leisure time and interests in environment and health have been increasing, the number of hikers who enjoy the beautiful landscape and regional culture through the exploration of natural regions has been growing. However, these various road haven't been related to the rural village in many cases, so it is necessary to make some alternatives for revitalizing the region and improving incomes of non farm. Therefore this study suggested the applications of rural trail plan that fits for a scale of the rural village and local characteristics. This research divided forms of the rural village road into type of the natural landscape resource (Gangreung Anbandegi Village) and that of the historical culture resource (Yongin Hakil Village) according to amenity resources of objective village. The plan for village road basically made by the best of valuable resources of village unit, connected existing 'Trail' of other departments to the village and suggested a case of plan applied to the field so as to emphasize characteristics of rural area. It should be possible to induce hikers to rural area and be suggested as a measure for improvement of village image, regional vitalization and incomes of non farm.

This study was conducted to investigate the user's effects on the avifauna in Kaya Mountain National Park. The survey was carried over 3 districts which were divided with main trail(valley), subtrail(valley), unused trail(ridge) by line transect method from April to October 1989. The observed birds were 29 species and 527 individuals. these consist of 20 species for residents, 7 species for summer visitor 1 species for winter visitor, 1 species for passage migrant. The average density of birds was 2.44 ea/ha, and main dominant species were Parus major minor, Garrulus gtandarius brandtii, Parus palustris hellmayri, Parus varius and Sitta europaea amurenis in order. The observed frequency of wild birds was 8.42 times/km in average. No. of species, no. of individuals, density, species diversity and observed frequency of summer were lower than spring in 3 survey routes. Therefore, from now, in Kaya Mountain National Park management, the enjoyment oriented activities will be regulated and control of trail use on main trail are necessary during breeding periods for wild birds protection, especially in summer. To investigate the use or not of artificial nests, 35 artificial nests were selected. The results of this survey showed that many wild birds prefered mixed nest in column shaped to wooden nests. The rightful installation and manegement for invitation and increase of wild birds was necessary.

The purpose of this study is to offer the raw data for restoration and management of trails by assessing the physical environments, the types of deterioration and the naturalness on trails located in the Sogeumgang, Hwarang and Seoak districts of Gyeongju National Park, Korea. The Sogeumgang was 5.9m, 1.1m of the Hwarang and 1.8m of the Seoak district in trail width. In the bared width of trail, the Sogeumgang was 3.9m, 0.9m of the Hwarang and 1.7m of the Seoak district. In the depth of erosion, the Sogeumgang was 37.1cm, 14.2cm of the Hwarang and Seoak district. The Sogeumgang was $16.8^{\circ}$, $13.1^{\circ}$ of the Hwarang and $12.2^{\circ}$ of the Seoak district in longitudinal slope. In the left and right of transect slope, the Sogeumgang was $18.3^{\circ}$ and $12.6^{\circ}$, $18.0^{\circ}$ and $21.3^{\circ}$ of the Hwarang and $15.3^{\circ}$ and $22.7^{\circ}$ of the Seoak district. In the left, middle and right of soil hardness, the Sogeumgang was 29.9mm, 34.7mm and 31.1mm, 27.6mm, 35.0mm and 27.2mm of the Hwarang and 27.1mm, 30.8mm and 28.0mm of the Seoak district. The types of deterioration in trails were 10 types of the Sogeumgang, 11 types of the Hwarang and 9 types of the Seoak district. The trail erosion, rock exposure and root exposure were substantially observed in the types of deterioration. In the results of the naturalness assessment, the Hwarang district was a good condition, but the Sogeumgang district was bad. The indicators of the Sogeumgang district were mostly poor.

The purpose of this study was to analyze biomechanical factors of trail running shoes applied to korean shoe-lasts. 10 healthy male subjects with an average age of 37.2 years(SD=8.28), weight of 69.6 kg(SD=10.56) and a height of 171 cm(SD=4.93) were recruited for this study. Ten males walked on a treadmill wearing four different shoes. Foot pressure data was collected using a Pedar-X mobile system(Novel Gmbh., Germany) operating at the 1000 Hz. Surface EMG signals for tibialis anterior, gastrocnemius, vastus lateralis and biceps femoris were acquired at 1000 Hz using Noraxon TeleMyo DTS system(Noraxon Inc., USA). Foot pressure and leg muscle fatigue were measured and calculated during walking. The results are as follows: After walking 60 minutes, Type A showed a lower MPF. MPF values were significantly different from each muscle(p<.05). Therefore, Type A shoe might decrease muscle fatigue in the legs while walking. In addition, Type It showed that Type A shoe has the highest contact area and the lowest maximum pressure. As a result of the analysis, Trail running shoes will use a new design to reduce muscle fatigue and are expected to increase comfort and fitting.
