Objective: Much has been known that the systematical theory of acupuncture was developed from stone needle as therapeutic tools for orthopedic diseases in ancient times. Stone needle is very old therapeutic method like moxibustion and has been recognized that it was developed since the Stone Age in China so far. In the present study, it was examined for the origination and formation of stone needle based on stone relics of the Stone Age in Korean Peninsular, the medical and geographical literatures. Materials and methods: The facts of stone needle was examined and arranged on the ancient medical or geographical literatures such as The Yellow Emperor's Canon Internal Medicine, Shanhaijing as an ancient geographical book, etc. The clan societies and family related to an origination of stone needle was chased together with their cultural characteristics and origination. The stone relics which have been digged out of historic sites in the North-East Asia were examined for a relevance to stone needle. Results: In The Yellow Emperor's Canon Internal Medicine, it was referred to the stone needle that originated from a fishery zone related to the east coast district in North-East Asia. Through the examination of Shan Hai Jing as an ancient geographical book and its historical reviews, a Go-yi clan society who keep Go's family tree dealt well with the stone needle and jewels including jade in the North-East Asia before the publication periods of The Yellow Emperor's Canon Internal Medicine, and is comprised in the culture of Dong-yi clan society but not the Chinese culture. The obsidian stones, which have been digged out of historical sites in the North-East Asia since the Stone Age, are originated from volcanic areas combined with seashore that seems to be Baekdu mountain district in Korea and Kyushu district in Japan. Furthermore, obsidian stone tools which were found out at Laodung peninsula and the Korean peninsula are archeologically similar to the stone needle with regards to the shape, size and dual-use. In addition, specific obsidian stone tools have been used in orthopedic surgery as well-crafted obsidian blades have a cutting edge up to five times sharper than high-quality steel surgical scalpels. Conclusion: The origin of obsidian stone needle is well corresponded to the explanation about that of the stone needle. It is suggested that the stone needle which influenced in completion of acupuncture and Meridian theory in China seems to be an obsidian stone, and distribution of obsidian stone needle has been closely connected to Dong-yi clan society which are lived in the North-East Asia including Baekdu-mountain district.

Chunghahk-dong is located in a retired spot, Jiri Mountain and has been built up its won religion and culture without any exchange outside world. People in Chunghahk-dong believe in a religion called Genjungyutaosim. Forming a trinity on which mind is Taoism, body is Buddhism, and behavior is confucianism. These are the principle elements to form a village. They made their own unique cultural factor such as longhaired boys and girls, wearing traditional cloths and hat, a monastic life, folk mores and family rituals, and private school system. This shows a great deal of affection on their life style and organization and is closely connected with community and culture. Grasping a culture and behavior on clothing, it has propose to understand Chunghahk-dong properly according to this study. A method of study has a purpose to understand culture and clothing behavior precisely in Chunghahk-dong. I inquire ito clothing behavior with investigation and study of picture script. The results are as followed; People in Chunghahk-dong show unique clothing and hair style behavior based on Genjungyutao. First, men and women wear a white cloth called HanBok(Korean costume) and footwear made of rubber. Only men wear a blue vest. A grown up men wear a long coat when they go out. They are dressed in tractional cloth for a ceremonial occasion. The reason why they put on the HanBok(Korean costume) is a belief on our traditional cloth becomes a standard dress in the future. They believe Korea becomes a standard dress in the future. They believe Korea becomes a standard dress in the future. They believe Korea become a leading country in the world. This clothing behavior is symbol of Genjungyutao and has a role of delivery system for expressing their split. Second, In sign of being a Genjungyutao men, they let their grow hair. Cutting hair is not to be a Genjungyutao men any more. There is few reason that people in Chunghahk-dong let grow their hair : First, because of importance in TanGun's ideology, they believe Korea is a first nation in the world and can't cut their hair which has grown from TanGun (The founding father of the Koran nation) Chosun traditionally. Second, Cutting their hair runs counter to the principle of nature. Third, They value their body for confucianism. They don't want to damage their body because of body from their parents. Boys and girls braid and tie up their hair and adult tie a topknot and a chignon. Wearing a YouGun(A horsehair skullcap) at home and Kat(A Korean top hat) when going out, they express as a Genjungyutao. Hemp cloth and synthetic fibers are main clothes. Also, they wear an improved HanBok(Korean costume) these days on influence outside.

During the last few decades in Korea, the development of hillside or mountain areas has rapidly increased for infrastructure construction such as railroads, highways and housing. Many landslides have occurred during these constructions. Also, the amount and scale of damage caused by landslides have increased every year. In the case of Far East Asia including Korea, the damage of landslides is consequently reported during the wet season. In this paper, the effect of stabilizing piles on slope stability is checked and the behavior of slope soil and piles are observed throughout the year by field measurements in the large-scale cut slopes. In particular a large-scale cut slope situated on the construction site for the express highway in Donghae, Korea. First of all, The behavior of the slope soil was measured by inclinometers during slope modification. Landslides occurred in this area due to the soil cutting for slope modification. The horizontal deformations of slope soil gradually increased and rapidly decreased at depth of sliding surface indicating that the depth of sliding surface below the ground surface can be predicted. On the basis of being able to predict the depth of the sliding surface, stabilizing piles were designed and constructed in this slope. To ensure the stability of the reinforced slope using stabilizing piles, an instrumentation system was installed. The maximum deflection of piles is measured at the pile head and it is noted that the piles deform like deflection on a cantilever beam. The maximum bending stress of piles is measured at the soil layer. The pile above the soil layer is subjected to lateral earth pressure due to driving force of the slope, while pile below soil layer is subjected to subgrade reaction against pile deflection. As a result of research, the effect and applicability of stabilizing piles in large-scale cut slopes could be confirmed sufficiently.

Disasters like mountain landslides and collapse in cutting areas claim many a life and cause economic losses, involving much effort and expenses for their recovery. This study has surveyed and analyzed incident of disasters that had occurred on the sloping sides in Korea for the past 13 years in an effort to relieve damage caused by disasters on the sloping sides. The analysis confirms that while the major cause of disasters on the sloping side was storms in the past, frequency of disasters on sloping sides caused by local downpour is steadily on the rise. In addition, while disasters were concentrated in Gangwon Province, a mountainous region of the country, frequency of disasters occurring on the sloping sides is steadily increasing recently on the sloping sides in downtown areas in Seoul, Gyeonggi-do and so forth, attributing a large percentage of disasters to sloping sides. Data surveyed and analyzed in this study are thought to be applicable as basic data for the establishment of effective measures for the prevention of disasters occurring on the sloping sides in the days to come.

Enlargement of street tree planting area is the proper and effective solution to reduce carbon dioxide. This solution bases on the ability of carbon storage and uptake by tree metabolism. However, the circumstance of road side has fatal disadvantages in tree metabolism such as growth and maturity because cutting and filling of roadsides cause unnatural soil composition. In this point, early rootage of street tree is the main factor of reducing carbon dioxide. This study aimed to find a appropriate transplantation planting method for sound and rapid rootage of street tree. For the study, Korean Mountain Ash(Sorbus alnifolia) were used for experimental groups. The groups were categorized by three groups such as trees produced on container with mulching treatment, trees produced in outdoor with mulching treatment, trees produced on container with weeding treatment. Each group consisted 10 trees with same size and transplanted in experimental site. Five months after transplanting, each group was estimated the biomass and carbon storage through a direct harvesting method. According to results of the study, the carbon storage of trees produced on container with mulching treatment is 42% more than trees produced in outdoor with mulching treatment. And the carbon storage of trees produced on container with mulching treatment is 19.5% more than trees produced on container with weeding treatment. These results may imply that transplantation of container produced tree with mulching treatment is the most rapid rootage among other groups. The weeding treatment is more effective than mulching treatment for rapid rootage of street trees.
