Medications or conitive-behavior methods have been mainly used as a treatment of alcoholism, lately the virtualy technology has been applied to the kink of alcoholic disorders. A virtual environment makes him having avility to over come the drink. In this study, we were implemented by making panorama images and 3D object modules using 3D MAX. VRML, JAVA. And the BAR stimulator that composed with a position sensor, head mount display, and audio system, is suggested. To illustrate the physiological difference between a person who has a alcoholism and and without a liquor bottle, heart rate was measured during experiment, and also measured a person's HR after the virtual reality training. We demonstrated the subjective effectiveness of virtual reality psychotherapy through the clinical experiment.

플라즈마화상 계측 시스템에 있어서의 시준기특성의 보정

백승권 인제대학교 1995 仁濟論叢 Vol.11 No.1

플라즈마화상 계측 시스템에 있어서, 단층화상의 화질이 떨어지는 문제점 중의 하나로서 검출기의 시준기특성이 있다. 이것은 시준기가 길이를 가진 형태이기 때문에 생기는 것으로써, 화상에서는 천이변형의 왜곡으로 나타난다. 본 논문에서 보정법으로 측정데이타를 공간주파수 상에서, 천이불변형태로, 디콘볼루션 하는 방법을 제시하고, 시준기의 각도를 파라메타로 해서, 플라즈마 계측에 의한 실제의 데이타에 그 보정법의 유효성을 검증하였다. In plasma image measurement and control system, one of the distortions of a reconstructed image is related to a collimator system. The distortion, which has a shift-variant property, is caused by a geometrical structure of the collimator. We developed a correction method considering this property. The correction is performed in the frequency domain. The conception of the correction method is that the blurring function is defined at the circular position of the polar coordinate in the frequency domain. The cyclic deconvolution of projection data with the shift-variant blurring function is effective to remove the distortion. In the paper, we considered the effect of aperture angle. The applicability to practical studies was discussed.

판재위에 배치된 2차원 형상들의 최적 잘던 경로에 관한 연구

백승수,김종민,김민환 부산대학교 1995 生産技術硏究所論文集 Vol.48 No.-

There are many methods for cutting out 2D shapes arranged on the plane. For increasing productivity, it is very important to select proper cutting path. In this paper, we propose an algorithm for optimizing cutting path among the 2D shapes. The algorithm uses minimum distance information between some pairs of neighboring 2D shapes and represents the arranged shapes as a weighted graph. Then, we can get the optimal cutting path by constructing minimum spanning tree from the weighted graph. 2차원 평면의 판재 위에 배치되어 있는 형상들을 절단하기 위한 방법은 여러 가지가 있고, 적절한 절단 경로의 선택은 생산성을 높이는데 아주 중요한 요소이다. 본 논문에서는, 형상들의 절단 경로를 최적화 하는 알고리즘을 제시한다. 본 논문에서 제시하는 알고리즘은 이웃하는 형상들 간의 최소 거리 정보를 이용하여, 배치된 형상들을 가중치 그래프(weighted graph)로 나타낸다. 형상들 사이의 최적 잘단 경로는 주어진 가중치 그래프에서 최소 스패닝 트리(minimum spanning tree)를 추출하여 구하게 된다.

골프지도자의 자격유형에 따른 교육적 기반과 생활환경에 관한 연구

This study aims to provide cultural and technical information and data on golf instructors' educational and personal life and their social status by closely examining their lifestyle revolving mostly around the golf range. After entering into the world of golf, many, if not all, of them commit themselves fully to golf in terms of money and effort over a long period of time in order to improve skills as a golfer. And after playing in a number of amateur golf tournaments and passing a sort of exams designed to test their qualification, they eventually get into the world of professional golf. Their life pattern changes gradually to suit a particular league or tournament. Through the change that often entails anguish and conflicts, golf players become more mature and develop ability to teach others. Starting fresh as an instructor, they attempt to teach students based on strategies and skills, which are systemized to some extent but focused mainly on practical training at the same time. In this period of their life, golf instructors usually try to rectify personal shortcomings and improve financial conditions while bracing for a second life as a player. These efforts, however, bring both positive and negative emotions to them. Consequently, they become confused as to what their own identity really is. And they instinctively try to get over this hardship through self rationalization. But the anguish and conflicts bothering them are not easily removed. The study result mentioned above gives us problems as well as implications to consider from the viewpoint of pedagogy, and they are as follows: First, as the function of a golf range and golf-related policies is tilted overly toward profit-making not just in terms of the substitution effect relating to physical education and workout practiced in daily life but also in terms of "money earning more money," golf is largely commercial and private. That commercial motivation prevails over educational functionality when it comes to a golf range or related policies is a serious matter. Therefore, a large sum of investment is absolutely necessary to nurture an excellent player. And this is why golf is regarded by many ordinary people as something very different from other sports. In view of this peculiar aspect, agencies and organizations responsible for raising and training golf players and instructors must offer programs that are designed to provide effective and practical training to those aspiring to become a player or an instructor. In so doing, they need to pay attention to cost saving and other productive measures so as to ultimately transform golf education into a complementary/substitute means to traditional physical education and daily physical exercise. Second, in most cases, golf ranges and instructors seem to devote too much of their time and resources to teaching practical skills and tips rather than to developing intellectual capability and educational acumen of students and trainees. This problematic aspect or trend, which stems largely from Korea's elitist physical-education policy, can be wiped out only when we do away with excessive commercialism and materialism noted by endless pursuit of mundane fame and wealth and instead assign a higher level of value to the education designed to teach true knowledge and morality. Also, a systematic educational foundation should be prepared so that golf can be accepted and played more widely in the future. Third, the job insecurity and low social status of golf instructors make their attempt at second life as a player all the more difficult. The two problems also push golf instructors to focus increasingly on money-making. The unstable identity of golf instructors is directly related to the current educational environment in which a golf instructor is perceived to be teaching practical skills for a particular sport instead of teaching physical-education in a broad sense. Solving the less-than-desirable situation requires institutional support in the form of proper environment for various physical activities and feedback, seminars on continuing education, public space for self development, education-related public offices offering space, assistance and incentives, and job security. Fourth, we are living in the era of "education inflation" here in Korea. Educational background must not mean everything in and for one's life. But it may be necessary for an instructor to gain confidence and respect from the public. In this regard, if it is deems that the overall level of education for golf instructors is low, it is important to add more programs and classes to the existing curriculum so as to help instructors develop intellectual strength to work comfortably with complicated topics. It is true that the word 'golf instructor' still sounds strange to ordinary people and even some of those involved in physical education. But this much is true. Golf instructors are shouldering their share of the burden for physical education, and their endeavor is making golf become more and more popular. confused due to irrational circumstances and policies, golf instructors in Korea, however, will surely play a pioneering role for the nation's future education. In consideration of this, the government must actively lend a helping hand to them.
