C. H. OH, S. N. CHOI, I. S. JEONG. Kinematic Analysis of the Badminton Drop-shot Motion. Korean Journal of Sport Biomechartics, Vol. 15, No. 1, pp. 221-235, 2005. The purpose of this study was to analyse badminton players' drop-shots, in order to make players understand the principles of drop-shot motion in badminton. Three dimensional analysis was used to measure movements such as the time required per section, the change of center of gravity, joint angle and speed, and joint speed. The results of this study revealed as follows: (1) top players are faster than amateurs in the total time required per section; (2) top players moved more in the x-axis and z-axis, while amateurs moved more in the y-axis; (3) the inclination of amateurs was greater than that of top players in all phases; (4) amateurs showed larger angle on the shoulder joints than top players in the first phase, while top players showed larger angle on the shoulder joint than amateurs in the second and third phase. Amateurs' angle was larger on angle joint in the first phase than top players' ones, while top players' angle was larger in the third phase than amateurs; (5) the speed of racket head of top players was faster than that of amateurs; and the velocity of the center of gravity of amateurs was greater than that of the top players. The findings of this study were that gravity decreases during impact and then the velocity increases to perform the follow-through and making the swing fast by increasing the speed of the racket head is most important.

Stenosis of central vein is a common complication arising after percutaneous subclavian vein catheter insertion performed for temporary vascular access in chronic renal failure patients undergoing hemodialysis. There are several treatment methods for the condition like percutaneous angioplasty(PTA), stent insertion, and surgery, but recent trend is toward PTA and stents. Among the patients diagnosed with chronic renal failure from March 1993 to May 2002 and undergoing hemodialysis through AV fistula, the 14 Patients in whom central vein stenosis arose were selected for the study. A total of 28 percutaneous interventions(5 PTA and 23 stent placement) were performed, and restenosis rate and the time taken till the restenosis in de novo lesions and instant lesions were compared. All 28 cases were operated successfully. The 14 cases that received both anigioplasty and stent placement initially. (de novo lesion : 14 cases), Among the 10 cases with de novo lesion that followed up more than 1 year, 3 cases are currently undergoing hemodialysis without restenosis, and the remaining 7 cases have recurred stenosis with the mean time to restenosis of 10.9 months. In the 7 cases in whom stenosis recurred, 11 interventions were done(instent lesion: 11 cases). 4 of these were using only ballon angioplasty with 100% restenosis rate and the mean time of 3 months until restenosis. The remaining 7 cases were using both balloon angioplasty and stent placement, also with 100% restenosis rate but with the mean time of 12 months until restenosis, which was later than the group receiving only balloon angioplasty. In treating the patients with central vein stenosis, stent placement seems to be more advantageous over PTA in terms of restenosis rate and the mean duration of patency. In the case of instent lesion, inserting the stent for the second time after stenosis recurred lengthened the duration of patency compared to performing balloon angioplasty alone.

To reduce farmer's stress from solar radiation and ultraviolet radiation(UV), the sunshade hat with a large brim and special structure for ventilation was developed and tested with manikin heads outdoors at previous study(Kim and Choi, 2002). To evaluate the protection efficiency of the sunshade hat, human trial test was performed at outdoors. The results were as follows; Skin temperatures(7 sites), heatr rate, temperature inside the hats, temperature and relative humidity inside clothing on the back in wearing developed sunshade hat were significantly lower than those in wearing the controlled hat. In subjective sensation, subjects answered to feel significantly hotter, more humid and more uncomfortable in wearing the controlled hat. But relative humidity inside the hats was significantly higher in wearing developed hat. In rectal temperature, there were no significant differences between two hats.

Modified surgical technique for transposition of the inferior alveolar nerve followed by immediate placement of endosseous implants in mandibles with moderate to severe atrophy are presented. Five transpositions of the inferior alveolar nerve together with the installation of 10 implants were performed in four patients. The mean postoperative follow-up time was 17 months, with a range of 8 to 20 months. All implants with functioning pontics remained stable, with no mobility or symptoms of pain and infection during the follow-up period. Neurosensory evaluation was performed using the two-point discrimination test. Two patients had objective neurosensory dysfunction at postoperative, but all the nerve function were reported as normal by the patients 4 months postoperatively.

관광목적지 수명주기에 관한 연구동향과 과제

최정수 경북대학교 사회과학대학 지리학과 2003 地理學論究 Vol.- No.23

역동적인 관광목적지의 진화·발달과정을 일반화하는 여러 이론들 중에 가장 대표적인 이론으로 관광목적지 수명주기를 들 수 있으며, 관광목적지 수명주기는 관광목적지에 대한 마케팅과 전략수립을 위한 지침 및 예측도구이기도 하다. 지금까지 관광목적지 수명주기를 적용한 연구들은 많이 이루어져 왔으나, 연구대상지역이 주로 해변리조트나 섬에 한정되어 관광목적지 수명주기의 일반화에는 한계가 있다. 그리고 관광목적이 수명주기는 관광객수에 대한 장기간 역사적 자료의 회귀성, 관광객수 증감이라는 하나의 변수로 설명을 하고 있는 점, 관광자원이나 관광상품, 숙박, 지역에 따라 수명주기는 상이하게 나타나는 점, 단계별 특성 규명에만 치중하여 결과론적이고 정태적이라는 점, 관광목적지의 성격 변화를 간과한 점 등의 한계를 지니고 있다. 이를 극복하기 위해서는 다양한 관광목적지를 대상으로 한 연구의 축적, 관광목적지 수명주기 단계를 구분하는 측정지표의 보완, 연대기적 자료 분석 및 각 단계의 공급 및 수요 측면의 요인에 대한 질적 접근, 한 단계에서 다음 단계로 넘어갈 수 있었던 원동력 규명, 관광목적지의 공간성 변화 등에 대한 연구가 필요하다. 그러나 무엇보다도 다양한 관광자원과 성격을 지닌 기타 관광목적지에 대한 연구의 축적이 전제된다. The tourism destination life cycle is the most widely accepted theory of various ones which try to generalize the development process of tourism destinations. In addition, it can be a guide and a tool for marketing and other strategies to develop the tourism destinations. Many studies have been done using the tourism destination life cycle but most of the subjects of studies are limited to seaside resorts or islands, which means they have some limits to generalize the tourism destination life cycle. The tourism destination life cycle may have some problems: the lack of the data in the number of tourists over the long years; defining the development stages only by the number of tourists; different levels of the cycle in tourism resources, commodities, accomodations, and location; focusing on just result with examining only the characteristics of the each stage; ignoring the transition of the spatial characteristics as a tourism destination. In order to overcome these weaknesses, it is prerequisite that there be the accumulation of studies on tourism destinations with specific characteristics, the development of indicators to check out the stage of the cycle, the analysis of the data gathered over the long period, qualitative approach to supply and demand side in each stage, and discovering the driving force moving a stage to another phase and the change of the space in the tourism destination. But above all, the accumulation of the wide range of studies on various resources and traits of the tourism destination is needed.

雙務契約을 淸算하는 法理 : 給付返還을 중심으로

崔秀貞 한림대학교 법학연구소 2001 한림법학 FORUM Vol.10 No.-

Bei der Abwicklung eines gegenseitigen Vertrag konnen die mannigfaltigen Storungen auftreten. Dabei aus den verschiedensten Grunden kan der gegenseitige Vertrag auflosen. Wenn der Vertrag aufgelost wird, ergibt sich die Notwendigkeit, schon erbrachte Leistung wieder ruckgangig zu machen. Dazu bedarg es regelmaβig eines Schuldverhaltnisses mit umgekehrten Parteirollen. Fur ein solches Schuldverhaltnis zur Ruckabwicklung kommen verschiedene Anspruchsgrundlagen in Bertacht. Die beiden wichtigsten finden sich in den Vorschriften uber den Rucktritt und die ungerechtfertigte Bereicherung. Die beiden Haupttypen fur die Ruckabwicklung von Leistungen, Rucktritt und ungerechtfertigte Bereicherung, fuhren zu einer Verschiedenheit des Anspruchsinhalts. Obgleich die Ruckgewahr wird in gleicher Weise sowohl nach Rucktritts-wie nach Bereicherungsrecht geschuldet, wenn die ruckgangig zu machende Leistung noch unverandert zuruckgewahrt werden kann, wohl aber tritt die Verschiednheit bei bestimmten Komplikationen hervor, z.B. Schadensersatz, Nutzungen, Verwendungen und Storungen der Ruckabwicklung. Aber das Ruckabwicklungverhatnis beim Rucktritt oder nach Bereicherungsrecht ist auch das Schuldverhaltnis mit umgekehrten Parteirollen, und es geht um die Leistungskondiktion. Daher laβt sich das Synallagma durchfuhren. Nach der Ansicht gibt es der wesentliche Unterschied nicht zwischen den beiden Typen.

생태관광과 로컬 거버넌스

최정수 한국경제지리학회 2003 한국경제지리학회지 Vol.6 No.1

생태관광은 보전과 개발이라는 상반된 이념의 조화로운 추구를 목표로 하는 대만관광의 한 형태이다. 생태관광의 성공 및 존립 여부는 생태관광자원만으로 보장되는 것이 아니다. 즉, 지방 커뮤니티(local host community)의 발전과 자연·문화자원의 보전이라는 공동목표 하에서 생태관광을 둘러싼 다양한 주체들간에 자원 및 정보의 공유, 합의와 이해를 이끌어낼 수 있는가에 달려 있다. 따라서 본 연구는 생태관광 존립에 있어 생태관광 관련 행위자들의 역할과 제도적 환경의 중요성을 규명하고, 로컬 거버넌스가 생태관광에 있어 지니는 의의를 살펴보았다. 그리고 로컬 거버넌스의 3가지 구성요소를 중심으로 행위자들간의 활발한 상호작용을 위한 환경 조성, 행위자들간의 효율적인 상호의존성, 그리고 이들 행위자들간의 관계 형성에 있어서의 구축방안을 제시하였다. 무엇보다도 로컬 거버넌스의 구축은 사회자본을 토대로 신뢰와 협력의 문화가 정착됨에 따라 더욱 용이해진다. Ecotourism is widely known to be a sort of alternative tourism which seeks to keep balance between conservation and development. Successful ecotourism is not just dependent upon natural/cultural resources but also the consensus-building and collaboration among actors involved in the development of ecotourist attractions. In this sense, the establishment of good local governance can be crucial to achieve both conservation and development which are incompatible one another. Governance is carried out through self-organising, inter-organisational networks, which is emerging as new forms of collective decision-making at local level. Governance leads to the development of different relationships, not simply between public/ nonpublic agencies but between citizens and public/nonpublic agencies. I represent some key dimensions to construct good local governance in ecotourism: i) the creation of socio-institutional milieu that facilitate interactions among actors related to ecotourism; ⅱ) actors involved in ecotourism taking responsibility to play an appropriate role in their own position. I argue that interactive relationships and consensus-building between different actors can be promoted by collective actions such as the sharing of information and resources, co-education and co-training, and seminars. It therefore implies that local good governance cannot be established without local social capital based on trust and cooperation between actors.
