Objectives : Six command points are individual points that have strong and broad effects on their related part of the body, but there is a controversy about which acupoints are should be included in the six command points. This research was reviewed which acupoints are suitable for the construction of the six command points. Methods : We searched acupoints mentioned six command points in literatures, then investigated the effects of the acupoints to identify that they can be included in the six command points. And we deliberated which acupoints are suitable for the six command points. Results : Acupoints mentioned the six command points are LU7, LI4, ST36, BL40, PC6, TE6, GV26, ouch point, GB34 and SP6. Among the acupoints, LU7, LI4, ST36, BL40 and PC6 was included in the six command points in all of searched literatures. And GV26, ouch point, GB34 and SP6 were excluded because GV26 and ouch point were not fit the definition of the six command points, ST36 can be an alternative to SP6 based on their effects, and GB34 has a similar but little effect compared to TE6. Conclusions : Based on the definition of six command points and the effect of the acupoints, we suggest that the six command points should be composed of LU7, LI4, ST36, BL40, PC6 and TE6.

Objectives : The aim of the study is to analyze various studies subjected to sachonghyeol (SCH; Four command points) including ST36, BL40, LU7, LI4 in Korean literature. Methods : To analyze the results of SCH studies, The search was made through OASIS database. The search terms used were "ST36 OR BL40 OR LU7 OR LI4". Of 147 papers, 2 irrelevant papers were excluded and finally 145 papers were analyzed. Results : Thirty two studies were associated with pain control in various conditions using SCH. The pain control study of SCH covered 22 % of total studies. The next study topic was digestive function of SCH. Conclusion : To expand the clinical usage of SCH, the studies based on regulating function of SCH on ascending and descending ki, and coming in and out of ki are required to be performed in the future.

In mold and die shops, NC machining process mainly affects the quality of the machined surface and the manufacturing time of molds and dies. The estimation of NC machining time is a prerequisite to measure the machining productivity and to generate a process schedule, which generally includes the process sequence and the completion time of each process. It is required to take into account dynamic characteristics in the estimation, such as the ac/deceleration of NC machine controllers. Intensive observations at start and end points of NC blocks show that a minimum feedrate, a key variable in a machining time model, has a close relation to a block distance, an angle between blocks, and a command feedrate. Thus, this study addresses regression models for the minimum feedrate estimation on short and long NC blocks considering these parameters. Furthermore, machining time estimation models by the four types of feedrate behaviors are suggested based on the estimated minimum feedrate. To show the validity of the proposed machining time model, the study compares the estimated with the actual machining time in the sculptured surface machining of several mold dies.

Major deficiencies of current automation scheme including various robots for bioproduction include the lack of task adaptability and real time processing, low job performance for diverse tasks, and the lack of robustness of take results, high system cost, failure of the credit from the operator, and so on. This paper proposed a scheme that could solve the current limitation of task abilities of conventional computer controlled automatic system. The proposed scheme is the man-machine hybrid automation via tele-operation which can handle various bioproduction processes. And it was classified into two categories. One category was the efficient task sharing between operator and CCM(computer controlled machine). The other was the efficient interface between operator and CCM. To realize the proposed concept, task of the object identification and extraction of 3D coordinate of an object was selected. 3D coordinate information was obtained from camera calibration using camera as a measurement device. Two stereo images were obtained by moving a camera certain distance in horizontal direction normal to focal axis and by acquiring two images at different locations. Transformation matrix for camera calibration was obtained via least square error approach using specified 6 known pairs of data points in 2D image and 3D world space. 3D world coordinate was obtained from two sets of image pixel coordinates of both camera images with calibrated transformation matrix. As an interface system between operator and CCM, a touch pad screen mounted on the monitor and remotely captured imaging system were used. Object indication was done by the operator’s finger touch to the captured image using the touch pad screen. A certain size of local image processing area was specified after the touch was made. And image processing was performed with the specified local area to extract desired features of the object. An MS Windows based interface software was developed using Visual C++6.0. The software was developed with four modules such as remote image acquisiton module, task command module, local image processing module and 3D coordinate extraction module. Proposed scheme shoed the feasibility of real time processing, robust and precise object identification, and adaptability of various job and environments though selected sample tasks.

본 논문은 한 대학에서 3년에 걸쳐 실시한 토익 모의고사를 바탕으로 4주간의 집중코스와 한 학기에 걸쳐 진행되는 상시적 토익코스의 점수 분포를 비교하고, 두 프로그램에 참여한 학생 그룹의 능력 뿐만 아니라 사용된 교수용 교재 및 장비를 살펴본다. 해당 대학은 여름방학과 겨울방학을 이용하여 4주간의 토익 집중코스를 개설하고 있으며, 참여 학생들은 오전 9시부터 오후 4시까지 수업에 참가한다. 또한 해당 대학은 매 학기동안 15주간의 상시적인 토익코스를 개설해서 월요일부터 금요일까지 매일 한 시간의 수업을 진행한다. 본 논문은 EFL/ESL 교육에서 교사가 교수 자료, 교수법 및 e-학습을 효과적으로 운용하는 것이 얼마나 중요한지를 보여준다. 상시적으로 개설되는 토익코스는 한 학기동안 75시간 수업이 진행되며, 4주간의 집중코스는 120시간 수업이 진행된다. 이 두 코스의 제한된 시간들은 학생들이 일상생활에서 의사소통을 가능하게 하는데 필요한 충분한 시간이라고 볼 수는 없다. 미래에 학생들이 영어 학습에서 성공적인 향상을 보이기 위해서는 효과적이고 질적으로 우수한 EFL/ESL 집중코스의 개발이 필수적이다.

항공수요의 급속한 팽창으로 항공기 운항의 증가와 공역 및 활주로의 혼잡도 심화로 인해 운영상 위험(Operational risk)이 급증하고 있어 체계적인 항공안전에 대한 위기관리시스템의 구축이 필요하다 항공안전 분야의 선진국일수록 평상시 비상대응체계 및 여러 가지 위험관리기법을 가동함으로써 조직의 긴장감 유지 및 예방안전의 도구로 활용하고 있다. 따라서 항공운송산업의 안전에 대해 총괄적인 관리 감독의 의무가 있는 항공안전본부 차원에서 이와 같은 과학적인 위기관리 모형을 이용한 위기관리체계의 도입이 필요하다. 위험요인분석 기법들은 데이터베이스가 구축되어 있거나, 충분한 정보와 자료가 있는 경우에는 사용될 수 있으나 현재의 국내 여건 상 충분한 자료의 확보가 곤란하여 실용적으로 사용되기가 어려운 것이 현실이다. 따라서 본 연구에서는 현재의 제한된 자료를 사용하여 실현가능 한 위험관리모형을 제시하기 위해 위험인자를 선정하고 각 위험인자에 대한 중요도와 발생빈도를 계산한 후 위험관리 모형을 제시하였다 이러한 위험관리 모형을 통해 항공운송분야에서 주기적 위험관리를 효과적으로 시행하기 위해서는 반드시 국가차원의 광범위한 자료의 수집이 선행되어야 한다.
