Objection : A medicine which is patient-initiative and preventive is required in Korea, which is going to an aging society. On this, we started this study to make a new rule to diagnose and treat more definitely by linking traditional Oriental medicine to Sasang Constitional medicine, which thought to be suitable because of Sasang Constitional medicine has been valued on staying, diet and human's nature which means preventive medical propensity. Methods : On this study, we discriminated Sasang Constition of 161 students, who is in college of oriental medicine, Wonkwang university, by using QSCCII program; and in those students, we checked 30 volunteers's five vicera's Back-su point on riging and depression, tenderness reaction, and color reaction after cupping treatment. Results : As a result of study of riging and depression of five vicera's Back-su point, we could confirm that defecient organ's Back-su point were more depressed than excess organ in Seum-in, Taeeum-in, Soyang-in. As a result of study of tenderness reaction of five vicera's Back-su point, we could confirm that excess organ's Back-su point showed stronger tenderness reaction than defecient organ in Seum-in, Taeeum-in; and excess organ's Back-su point showed weaker tenderness reaction than defecient organ in Soyang-in. As a result of study of color reaction after cupping treatment of five vicera's Back-su point, we could confirm that excess organ's Back-su point showed stronger color reaction than defecient organ in Seum-in, Taeeum-in; and excess organ's Back-su point showed weaker color reaction than defecient organ in Soyang-in. Those data suggest that there are close correlation between Sasang Constition and on riging and depression, tenderness reaction, and color reaction after cupping treatment of five vicera's Back-su point in treditional Oriental medicine. Conclusions : From this study, we can make a new rule to differentiate Sasang Constition by clearfy a relation between Sasang Constition and five vicera's Back-su point; and with this rule, we could contribute to popularization and objectification of Sasang Constition medicine and further more, Oriental medicine by making a Sasang Constition diagnosis instrument. With this, a trait of Sasang Constition medicine that is preventive and valued on character of individuals will contribute to building a patient-initiative and preventive medical system and will expend the domain of Oriental medicine.

This study aimed to provide data for establishment of resource management system of Iriomote Island in Okinawa Japan. Nature resource management system of Iriomote Island can be categorized into eight stages which are equivalent to regional development stages. 1) Networking among local people, tourists, researchers, tour operators and government authorities enhanced collection of resource data. 2) On the early stage, resource data were available only to researchers and government authorities. From the third stage of this system, however, local people were also involved in resource investigation, so they became to well recognize the values of their local resources. 3) On the sixth stage, data on unfamiliar local resources and attractions became to be known to people by real-time data collection and data provision services. The tourist number gradually increased and their visitation patterns were dispersed into different sites and seasons. In addition, some tourists also participated in resource investigation and they were likely to visit the place again. 4) To achieve successful ecotourism development, it is necessary to establish a management system with a feed-back process to identify, evaluate, use and protect the resources.

본 연구는 양양연어축제를 통해 생태관광에서 '자연'이 '생산'되고 보존되며 이용되는 과정을 살펴보고 있다. 최근 관광지리 논의에서는 관광개발 과정에서 나타나는 자연의 신자유주의화와 이에 대한 정치생태학적 재해석이 이루어지고 있다. 한국에서는 양양군을 중심으로 연어보존이 이루어져왔고, 연어축제 역시 연어보존이 나타내는 자연의 복원이라는 상징성을 담고 있다. 그러나 연어축제는 연어의 상품화를 중심으로 이루어지고 있으며, 남대천은 연어의 생태계가 복원된 장소로 인식되기는 어려운 상황이다. 또한 연어회귀가 증가하지 않고, 축제의 외연적 확대가 어려워지면서 연어와 남대천 보존에 대한 지역의 관심은 예전과 같지 않다. 즉, 자연의 보존과 복원의 상징성을 강조하는 축제의 주장과는 달리 생태계를 위협하는 부정적인 요인들은 여전히 남아있다. 이로 인해 연어와 남대천의 보존과 관련한 행위자들 사이의 갈등이 발생하고 있으며, 이는 지역 주민들에서부터 지자체, 국가, 국제기구에 이르기까지 복잡하게 얽혀있다. 생태관광에서 이용되는 자연은 다양한 층위의 행위자들의 이해관계에 따라 선택적으로 정의되고, 이용되며, 강조된다. 이는 정치생태학 연구에서 강조되는 '생산되는 자연'의 개념이 본원적인 자연개념보다 축제의 주제로 전용되고 상품화되는 자연의 모습을 설명하는 데 유용하다는 점을 시사하고 있다.

There have been a series of debates to determine whether it would be possible to forecast dynamic systems such as stock markets. Recently the introduction of chaos theory has allowed many researchers to bring back this issue. Their main concern was whether the behavior of stock markets is chaotic or not. These studies, however, present divergent opinions on this question, depending upon the method applied and the data used. And the issue of predictability based on the nonlinear, chaotic nature was not dealt extensively. This paper is to test the nonlinear nature of the Korea stock market and accordingly attempts to predict its behavior. The result indicates that our stock market represents a chaotic behavior. We also found out based on our simulation that executing buy/sell transactions based upon forecasts which were derived using the local approximation method outperforms the decision of holding without a buy/sell transaction.

The purpose of this study was to analyze kinematic quantitative factors required of a forehand counter drive in table tennis through 3-D analysis. Four national table tennis players participated in this study. The mean of elapsed time for total drive motion was $1.009{\pm}0.23\;s$. At the phase of impact B1 was the fastest as 0.075 s. This may affect efficiency in the initial velocity and spin of the ball by making a powerful counter drive. The pattern of center of mass showed that it moved back and returned to where it was then moved forward. At the back swing, lower stance made wide base of support and a stronger and safer stance. It may help increasing the ball spin. Angle of the elbow was extended up to $110.75{\pm}1.25^{\circ}$ at the back swing and the angle decreased by $93.75{\pm}3.51^{\circ}$ at impact. Decreased rotation range of swinging arm increased linear velocity of racket-head and impulse on the ball. Eventually it led more spin to the ball and maximized the ball speed. Angle of knee joint decreased from ready position to back swing, then increased from the moment of the impact and decreased at the follow thorough. The velocity of racket-head was the fastest at impact of phase 2. Horizontal velocity was $7796.5{\pm}362\;mm/s$ and vertical velocity was $4589.4{\pm}298.4\;mm/s$ at the moment. It may help increase the speed and spin of the ball in a moment. The means of each ground reaction force result showed maximum at the back swing(E2) except A2. Vertical ground reaction force means suggest that all males and females showed maximum vertical power(E2), The maximum power of means was $499.7{\pm}38.8\;N$ for male players and $519.5{\pm}136.7\;N$ for female players.

본 연구는 남당 한원진의 철학사상, 특히 심성론을 비판적인 입장에서 논의한 것이다. 주지하다시피, 남당은 인물성(人物性)의 상이함을 강조해서 "인간의 가치와 존엄성을 공고히 하고자 했다"고 평가된다. 그러나 그의 이론체계는 결코 그런 목적을 지지하지 못했다. 우선, 그는 현실세계에 초점을 맞춰 "기선리후(氣先理後)"를 주장했는데, 이는 리의 존재론적 의미가 기에 의해 변질될 수 있다는 뜻으로 결국 리로 하여금 천지만물의 최종근거이자 순선한 도덕법칙이 될 수 없도록 만들어 버린다. 이런 논리가 심성론에도 그대로 적용되어, 결국 천지만물의 실제적인 성은 기질에 의해 변질된 리가 또한 기질과 뒤섞여 형성된 것이며, 현실적이고 구체적인 심은 기품에 의해 이미 그 '우열'이 결정되어 있는 인지능력을 가질 뿐이다. 이런 심성에 근거해서 우리가 어떻게 도덕을 실천할 수 있겠으며, 인간의 가치와 존엄성을 확보할 수 있겠는가?

PURPOSE: Text-mining has been shown to be useful for understanding the clinical characteristics and patients' concerns regarding a specific disease. Low back pain (LBP) is the most common disease in modern society and has a wide variety of causes and symptoms. On the other hand, it is difficult to understand the clinical characteristics and the needs as well as demands of patients with LBP because of the various clinical characteristics. This study examined online texts on LBP to determine of text-mining can help better understand general characteristics of LBP and its specific elements. METHODS: Online data from www.spine-health.com were used for text-mining. Keyword frequency analysis was performed first on the complete text of postings (full-text analysis). Only the sentences containing the highest frequency word, pain, were selected. Next, texts including the sentences were used to re-analyze the keyword frequency (pain-text analysis). RESULTS: Keyword frequency analysis showed that pain is of utmost concern. Full-text analysis was dominated by structural, pathological, and therapeutic words, whereas pain-text analysis was related mainly to the location and quality of the pain. CONCLUSION: The present study indicated that text-mining for a specific element (keyword) of a particular disease could enhance the understanding of the specific aspect of the disease. This suggests that a consideration of the text source is required when interpreting the results. Clinically, the present results suggest that clinicians pay more attention to the pain a patient is experiencing, and provide information based on medical knowledge.

The purpose of this research is to comprehend experimentally the nature of human static load to wall for making use of the result as basic data to evaluate resisting force of lightweight wall. Human motions exerting static load are classified to 4 types, and two-hands pushing and shoulder pushing are defined as the instantaneously forcing motions with hands or shoulder put on the load plate, respectively. Back leaning and one-hand leaning are defined as motions of taking a rest in their respective comfortable posture. Measurement of static horizontal load caused by each motion showed that the highest load ratio depends on hardness of load plane and was 1.17~1.25 times of weight in two-hands pushing, 0.95~0.99 times in shoulder pushing, 0.16~0.18 times in back leaning, and 0.12~0.15 times in one-hand leaning.

본 논문은 상대적으로 대비도 차이가 크게 나타나는 역광 이미지에 대해서 Retinex 알고리즘을 적용하여 보정 했을 경우 발생하는 밝은 영역에서의 컬러성분의 손실을 개선하기 위한 새로운 기법을 제안한다. 역광 이미지의 경우 밝은 영역과 어두운 영역에 대한 밝기 차이가 매우 크게 발생하기 때문에 Retinex 알고리즘을 이용하여 영상의 대비도를 향상시킬 경우 밝은 영역에서의 컬러 성분이 손실되는 현상이 발생한다. 이러한 손실을 보완하기 위해서 원본 영상의 밝은 영역에 해당하는 컬러 성분을 Retinex 알고리즘으로 보정된 영상에 추가해준다. K-mean 알고리즘을 이용하여 원본 영상에서의 밝은 영역, 어두운 영역, 중간 영역을 분리하고 밝은 영역에 대해서의 컬러 성분을 추가적으로 복원해 주며, 중간 영역에 대해서는 히스토그램에서의 위치를 기준으로 밝고 어두운 성분에 대한 비율을 고려하여 각 비율에 따라 원본 영상과 Retinex 복원 영상의 밝기 값을 함께 이용하도록 한다. 제안하는 알고리즘의 성능 평가를 위해 역광 현상이 강하게 나타나는 자연영상들을 대상으로 적용하여 기존의 Retinex 알고리즘보다 우수한 성능을 가지고 있음을 보였다.
