호주 연구진이 산맥을 따라 걷기 운동을 연구한 결과, 아래 경사를 따라 결으면 혈당 수치가 감소하고, 위 경사를 따라 결으면 콜레스테롤의 주요 성분인 중성 지방의 수치가 감소한다는 사실을 밝혔다. 또, 아래 경사를 따라 운동을 하면 당뇨의 발현 가능성도 감소할 수 있다고 한다. 당뇨병환자에게는 혈당관리가 당뇨병관리의 기본이다. 또한, 고혈압에 걸릴 확률이 일반인의 2~3배 더 높으며 심장질환이나 혈관계통질환은 당뇨병환자 증세를 나쁘게 만들므로 중성지방의 수치도 중요하다. 올봄 위, 이래 경사를 걷는 등산으로 혈당과 중성 지방 수치, 두 마리 토끼를 잡기 위한 당뇨인의 등산법을 알아보자.

지도는 지구표면의 입체적인 지형을 일부 또는 전부를 일정한 비율로 축소하여 자연물과 인조물을 규정된 기호로써 지면에 그린 것을 말하며, 등산 계획 및 산행에 있어서 절대적으로 필요한 것이다. 따라서 지도는 등산중에 언제나 손쉽게 펴 볼 수 있도록 휴대하여 등산중에 자기 위치를 알아보고 다음 목적지의 지형을 지도상에서 미리 연구한 후에 행동하여야 한다. 그러므로 지도는 산을 찾는 등산객의 눈이 되며 안내자가 되어 주는 것이다. 그렇기 때문에 독도법 훈련은 평소부터 가까이 하여 충분히 읽을 수 있도록 노력해야 하겠다.

Ridge traversing trail in Mount Jiri National Park is classified as flat, gully-like, unilateral, and asymmetric bilateral, paths based on a location and gradient of paths. These types are interchangeable due to a drainage condition of trail surfaces. Using a rapid survey, the trail is 135.9 cm wide, 23.6 cm deep and $5.1^{\circ}$ in a gradient, respectively. All treads have been compacted due to human trampling. The path width is affected by a slope aspect and a distribution of Sasa borealis. An asymmetric path is wider than a symmetric path. A soil erosion rate is equivalent to $68.9cm^2/year$ for the period from 1960 to 2009, suggesting that the trail has been widened 2.7 cm/year and the tread lowered 0.4 cm/year. Trampling and needle ice action combined with rainwash induced by a pipeflow are dominant erosion processes contributing to the trail expansion.

This research applies the climbing learning method that, a Japanese professor, Saito Noboru established and practiced, to fourth and sixth graders in an elementary school in order to analyze its effect on mathematical creativity, attitude toward mathematical creativity, so called CAS(Creative Attitude Scale) and academic achievement of the subject. The goal is to explore methods that can enhance students' mathematical creativity. To address these tasks, the research developed a teaching-learning scheme and learning structure chart that applies the climbing learning method. Next, the research organized two homogeneous groups among 124 students in fourth and sixth grades in S elementary school, located in the city of Busan. The experiment group went through classes that applied climbing learning method, while the control group received regular teaching. The following describes the research findings. After the experiment, the research conducted t-test for the independent sample based on the test result in terms of mathematical creativity, CAS and academic achievement of the subject. For mathematical creativity, all four constructing factor showed statistically significant differences at significance level of 5%. For CAS, statistically significant difference was revealed at significance level of 0.1%. However, in regard to a test of academic achievement for fourth and sixth graders, statistically significant difference was not detected at significance level of 5% even though the average score of the students in the experiment group was higher by 6 points. The research drew the following conclusion. Firstly, classes that apply climbing learning method can be more effective than regular classes in enhancing mathematical creativity of elementary school students. Secondly, the climbing learning method has positive impact on inclination for mathematical creativity of elementary school students. The research suggests that the climbing learning method can be an effective teaching-learning tool to improve students' mathematical creativity and inclination for mathematical creativity.

This study was conducted to investigate user, use characteristics and use pattern of Soknisan national park. In this study, the questionaire was used which was included the questions on socioeconomic variables of users, visiting motivations, attitudes on management and services, and so on. And to count the passingers, 9 observation points were selected. Visitor's important motivations were to escape from crowded city, to escape from daily routine, to enjoy natural seeing beauty, and so on. Their main activities were temple visit, stroll and mountain climbing. The visitor's composition showed that high school or more graduated twenties were respectively dominant. Perceived crowding level in this park were relatively high and most crowded area was Bupjusa area. Visitors had unsatisfactory attitudes on management and services as like trail, facilities, educational environment and others related services. Accordingly satisfaction level was comparatively low. A major portion of visitors merely visited Bupjusa area, only 15% and less climbed as far as top of mountain.

In order to examine the amount and rate of soil erosion on Ridge Traversing Trail in Jirisan National Park, a cross-sectional area of hiking trail were monitored at 16 sites in Nogodan - Samdobong section from November 2011 to April 2012. Although all sites demonstrates an enlarged cross-section of trail, the amount of soil erosion varies from site to site: 54.9 to $908.8cm^2$. It suggests that the erosional rate ranges from $0.1cm^2/day$ to $1.72cm^2/day$. The erosional amount is also varied with a trail type: $109.3cm^2$ for a shallow gully-like trail to $573.2cm^2$ for a unilateral trail. However, the cross-sectional change is larger on a sidewall than a tread irrespective of a trail type. The erosional amounts of November to April are smaller than that of May to October. In particular, the erosional amount of November 2011 to April 2012 is smaller than the depositional amount, implying a reduced cross-section of trail. Pipkrake action puts loose soil particles on a sidewall on March and April, and then rainwash due to a heavy rainfall takes them away after May. It seems to be the most predominant erosional process in Ridge Traversing Trail. A sidewall facing north shows a larger amount of erosion than a sidewall facing south. It also implies a difference in the development of a pipkrake according to an aspect. The small amount of erosion and cross-sectional decrease, which is usually observed on April, results from the combined effect of frost heaving, pipkrake action, a small rainfall and a temporary suspension of trampling. It is necessary to establish the monitoring system of trail erosion in terms of the management of hiking trail in a mountain national park.

Mountain Chungyeong, 879m in altitude, is located in the northeast of the middle area in Korea. Around Mt. Chungyeong, many Korean endemic and rare plants are populated, so it is considered a very important biogeographical area where the temperature zones of northern and southern plants are crossed. Because it is close to Seoul, a capital of Korea, it is a common mountain where many tourists visit frequently. Continuous tourist's visit may cause a bad influence on vegetation around the climbing paths. Therefor, weed community around the climbing paths on Mt. Chungyeong, where visitors exert a bad influence directly on its community by coming in and out, was surveyed phytosocialogically. Our surveys have been accomplished from August, 2001 to September, 2002. weed communities formed around the climbing paths on Mt. Chungyeong were divided into several patterns and analysed. They have been divided into 5 communities and 5 subcommunities. Community A: Plantago asiatica community, A-a: Erigeron annuus subcommunity, A-b: Carex. lanceolata subcommunity, B: Pseudostellaria palibiniana community, B-a: Carex siderosticta subcommunity, B-b: Galium trachyspermum subcommunity, C: Pueraria thunbergiana community, D: Lespedeza maximowiczii community, E: Rubus crataegifolius community, F: Oplismenus undulatifolius community, The flora surveyed in these communities was constituted of 47 families, 101 genera, 17 varieties, and 149 species. Wild plants such as Plantago asiatica, Erigeron annuus, Erigeron strigosus, Pueraria thunbergiana, Lespedeza maximowiezii, Rubus crataegifolius, Artemisia princeps var. orientalis, Artemisia japonica and Lysimachia clethroides were mostly light loving plants and higher resistant plants against the stamping pressure. Our result from the ranking all surveyed areas by the Bray-Curtis ordination method was very similar to the results from phytosocialogical table analysis.
