Sprain is the injury of meridian-muscle, and is caused by qi and blood obstruction or regional stagnation of qi and blood. So we take the channel points where pain flows. If we take the locations that feel pain, those locations are treatments points and ashi points. So we searched over the ashi points appearing on the patients with wrist sprain. Ashi points appeared on LI5, TE4, SI5 around wrist joints, LI10, LI11, LU6 around elbow joints, LI14, LU3, LU4, PC2 around upper arm. Also, ashi points appeared much on ST17, KI23, PC1, SP18, ST18 around thoracic region, and, on BL15, BL44, BL13 around anterior and thoracodorsal region, in order stated. Ashi points of the highest frequency appeared on LI14 around upper arm, and on LI5, TE4 around wrist joint, and SI5, ST17, KI12, PC1, SP18 appeared with second highest frequency. And ashi points on elbow points and thoracodorsal region appeared with the same frequency. Therefore, it is possible for us to know that the pain location appears in order of upper arm, anterior thoracic region, elbow joint region, and, thoracodorsal region, in treating wrist joints. There was a tendency that pain and movement disturbance recovered more quickly, depending on the pain reduction, as we found out the ashi points closely from stagnated qi and blood caused by wrist arthritis, and relaxed the stiff location. Rubbing treatments in treating pain ashi points is considered to play an important role to reduce pain effectively, so it is necessary to make a further study.

Objectives : Chimgugyeongheombang's Byulhyul, or special points, is a list of extra points, and its acupoint types and positions are different from other books. Its source, however, is kept behind the vale. This paper aims to reveal Byulhyul's contents and source. Methods : Qixiaoliangfang, Jinjiudacheng, and Donguibogam's Gihyul were studied to determine the source of Chimgugyeongheombang's Byulhyul. Results & Conclusions : Chimgugyeongheombang lists a total of 59 special points. It cites 22 meridian points from Qixiaoliangfang, 26 points from Jinjiudacheng, and 36 points from Donguibogam. The Dictionary of Acupuncture records the source of 6 meridian points that aren't found in conventional books, namely the Soongol, Backro, Yeose, Eumdo, Naetaechoong, and Gabgeun points, as Zhenjiujicheng. However, Zhenjiujicheng, in reality, is a book put together with excerpts from three books: Donguibogam, Chimgugyeongheombang, and Leijingtuyi. This means that it's Chimgugyeongheombang that is the source of Zhenjiujicheng. Moreover, all of the points save for Soongol and Eumdo were also used in the acupunctural treatment of 9 diseases including epilepsy. In other words, it can be safely assumed that Heo Im came up with and utilized new special points based on his personal clinical experiences, and this is significant in that he expanded the boundary of the conventional study of acupuncture through his independent experiences and studies.

측량기준점은 측량을 포함한 지형공간정보의 생산 및 구축과정에 있어서 기본이 되는 매우 중요한 지형공간정보이다. 현재 우리나라의 측량기준점은 국가기준점, 공공기준점, 지적기준점으로 분류되며 생산, 관리, 운영의 주체가 측량기준점의 종류에 따라 다르다. 또한 측량기준점에 대한 일관된 형식 또는 표준이 정의되지 않아 측량기준점에서 제공되는 기본적인 정보가 상이하고, 측량기준점 간의 연계, 통합 활용 및 관리, 운영이 어려운 실정이었다. 따라서 측량기준점의 효율적인 생산, 관리, 운영, 유통을 위한 표준의 제정이 필요하다. 이에 본 연구에서는 측량기준점의 운영현황을 조사하여 표준의 작성을 위한 측량기준점의 대상을 선정하고, 국내 외의 측량기준점의 성과항목을 조사하여 측량기준점의 표준화 항목과 관리 데이터모델을 결정함으로써 기관표준 및 TTA표준을 제정하고 이를 활성화 할 수 있는 방안을 제시하였다.

The objectives of this study were to investigate the status of accidents and to assess hazards in institutional foodservices in the Changwon and Masan areas. A survey was conducted from February 1 to March 31, 2009 using questionnaires, and 142 dietitians participated. The dietitians' perception of accident risks in workplace averaged 3.11 points. Forty-five percent of the respondents responded that accidents had occurred more than once between 2006 and 2008. In addition, 28.2% of the respondents experienced employee absences or turnover due to accidents during Year 2008. 'Musculoskelectal injuries or disorders (65.5%)', 'slips or falls (64.8%)', 'burns (57.7%)', and 'cuts and punctures (48.6%)' were the predominant accidents in foodservice. 'Knives (76 points)', 'steam kettles (41 points)', 'vegetable cutters (34 points)' and 'turn kettles (26 points)' were the equipment with severe accidents, such as burns or cut injuries. Among foodservice processes, 'carpal tunnel syndrome while washing (2.83 points)', 'burned by frying oil (2.64 points)', 'cut by sharp tools (2.55 points)', 'musculoskelectal injury by moving heavy weight food materials (2.41 points)', and 'injury by slipping on wet workplace floors and trenches (2.19 points)' were the most frequently occurring accidents at foodservice sites. To prevent safety accidents, dietitians' perceptions of safety supervision should be improved, and therefore, it is necessary they receive safety education.

In this paper we have examined the linear stability of triangular equilibrium points in the photogravitational restricted three body problem when both primaries are triaxial rigid bodies, the bigger one an oblate spheroid and source of radiation. The orbits about the Lagrangian equilibrium points are important for scientific investigation. A number of space missions have been completed and some are being proposed by various space agencies. We analyze the periodic motion in the neighbourhood of the Lagrangian equilibrium points as a function of the value of the mass parameter. Periodic orbits of an infinitesimal mass in the vicinity of the equilibrium points are studied analytically and numerically. The linear stability of triangular equilibrium points in the photogravitational restricted three body problem with Poynting-Robertson drag when both primaries are oblate spheroids has been examined by A. Kumar (2007). We have found the equations of motion and triangular equilibrium points for our problem. With the help of the characteristic equation we have discussed stability conditions. Finally, triangular equilibrium points are stable in the linear sense. It is further seen that the triangular points have long or short periodic elliptical orbits in the same range of ${\mu}$.

Objective : To increase the safety of moxibustion by understanding moxibustion-prohibited points' distinguishing features through literary inquiry. Method : We searched for moxibustion-prohibited points in Traditional Oriental Medical literature. Results : 1. Upon the advancement of moxibustion technique, the numbers of moxibustion-prohibited points increased. 2. Both Foot Meridians and Hand Meridians have similar percentage of moxibustion-prohibited points. Both Yin Meridians and Yang Meridians have similar percentage of moxibustion-prohibited points. 3. The face has the highest moxibustion-prohibited points ratio. The Back has the lowest moxibustion-prohibited points ratio. 4. We research 80 moxibustion-prohibited points and find 31 moxibustion-prohibitive reasons. A key reasons is that heating effect of moxibustion damages tissues, organs and meridian functions. There are also cases where the moxibustion-prohibited points can be designated upon the patients condition Conclusions : We could learn the distinguishing characteristics of moxibustion-prohibited points from this study. These results suggest that the treatment of moxibustion is more useful and safe.

Given separated points divided by a line, called a wall, in a plane, we aim to make a gate in the wall to connect the separated points to each other. In this setting, the problem is to find a location for the gate that minimizes the average distance between the points. The problem is a variant of the well-known facility location problem, which is extensively studied in the fields of operations research, location theory, theoretical computer science, and so on. In this paper, we consider the $L^1$-distance of the points in the plane. The points are projected onto the wall and so the problem is transformed to a proximity problem of points on a line. Then it is shown that the transformed problem is related to the weighted median problem of points on the line. Therefore, we obtain an O(n log n)-time algorithm to solve our problem.
