Purpose: The purposes of this study were to provide information about safe actions during the practice of dental technology, promote belief in safe actions among the students of dental technology, and reinforce their knowledge about how to act safety. Methods: Open questions were asked to 120 sophomores majoring dental technology to understand the target group's belief about safe actions. Following the instructions by Ajzen & Fishbein, the collected data were grouped according to similar beliefs. Those beliefs of the highest frequency were given a priority and got to represent the belief level of the target group. Even with belief changes, however, they would not be able to practice safe actions if they had no knowledge about how to do safe actions. For desirable behavioral changes among the students, the students were then asked to discuss the current state of safety accidents and issues focusing on the materials and processes used in the practice and give presentations regarding the subjects to identify risk factors. Then the identified risk factors were used to devise the program contents so that the students could practice safe actions through accurate behavioral approaches and belief changes by educating them about how to act safely by the practice processes and the involved materials and devices. Results: Not only do the students of Dept. of Dental Technicians have difficulties with the complex practice processes while practicing to make dental prosthesis, but they are exposed to the risk of accidents as they're poor at dealing with the materials and devices. Although there is a definite need for accident prevention education programs before practice, the reality is that the school doesn't the schoosuch education. Based on the judgment that an education program designed to reinforce belief for behavioral changes would generate effgrams results, an education program was developed by applying the Theory of Planned Behavior(TPB). Along with their beliefs, the current state of accidents n. Basepractice, demand for safety education, and practice level of safe actions were used to device the contents of accident prevention education and to develop an accident prevention education program for dental technology. Conclusion: The study presents an accident prevention education program developed to reinforce dental technology students' beliefs and knowledge and to help them do safe actions during practice.

The importance of repeat screening for stomach cancer is well known to decrease deaths from stomach cancer. This study was aimed at assessing practice behaviors and to identify related factors in the aspects of demographic factors, health status and cancer risk recognition, attitude to cancer screening, health behaviors, and inhibiting or facilitating factors to stomach cancer screening in an urban area. Data was collected through self-administered questionnaires from 403 people aged 40 to 69 years from April 23th to May 15th, 2002. Practice behaviors were classified as : "ever" or "never", and "repeat" or "not repeat" grouped based on a recent 5 year screening history. The results were as follows: 1. Among the 403 subjects: "the ever group" was 23.8% and "the repeat group" was 4.0%, The rates of screening were 20.5% for men, 27.8% for those women, and 27.3% for aged 40-49, 24.5% for those aged 50-59, 19.0% for those aged 60-69. The rates of repeat screening were 4.0% for men, 4.1% for women, and 2.9% for those aged 40-49, 6.3% for aged 50-59, 2.5% for those aged 60-69. 2. The main factors associated with adherence to gastric cancer screening were education(post high school vs below : OR=2.44), previous cancer screening(yes vs no : OR=2.61), belief in personal health(no vs yes : OR=2.72), health status(unhealthy vs healthy : OR=3.40), possibility of cancer compared to others(low vs not low : OR=2.56), and regular exercise(yes vs no : OR=2.94). The main factor associated with adherence to gastric cancer repeat screening was other cancer screening(yes vs no : OR=6.33). Consequently, there is a need to change the recognition of the importance and necessity of stomach cancer screening in healthy conditions through health education, and to perform multiple screening tests each visit.

이 연구의 목적은 Balletfit의 원리와 그 프로그램 구조를 이해하고 신체모양의 변화와 자세 교정에 대한 Balletfit의 효과를 확립하는데 있다. 본 연구는 가장 일반적으로 사용되는 질적 연구 방법을 바탕으로 3개월에서 6개월 동안 Balletfit 개인 레슨을 주 2 회를 수강 한 10 명을 선정하였다. 이 참가자들은 깊이 있는 통찰력을 얻기 위해 그룹 레슨 대신 개인 레슨 참가자로 선발하였다. 본 연구는 소수의 참가자들에게만 국한되어 결과를 표준화하기는 어렵다. 또한 이 연구는 자세 측정 장치가 아닌 참가자의 의견을 토대로 하기 때문에 결과의 정확도 또한 제한적임을 밝혀둔다. 본 연구 결과는 다음과 같다. 첫째, 참여 동기는 인터넷 조사 또는 지인의 추천으로 운동을 시작한 경우가 대부분이었다. 둘째, 자신의 신체를 인식하고 자세를 교정하려고 노력하고 있었다. 셋째, 이상적인 자세로 회복되었다. 대부분의 참가자들은 이상적인 자세가 무엇인지를 알게 되었고 참가자의 신체가 이상적으로 변화되어 참가자는 내/외부 신체를 인식하여 건강을 회복했다. 마지막으로, 그들은 아름다운 바디 라인을 선호하는 경향이 있었다. 경험 후에 모든 참가자들은 바디 라인에 관심을 갖게 되었고 올바른 자세로 아름다운 바디 라인을 만드는 것을 선호했다. Balletfit의 가장 중요한 효과는 바디 라인이다. 따라서 Balletfit의 경험은 내외부의 신체 인식을 발전시키고 신체 형태의 변화에 영향을 미칠 수 있다고 본고는 바라본다. Balletfit은 아름답고 건강한 신체를 원하는 현대인에게 만족스러운 운동이 될 것이다.

Objectives: Although electro-acupuncture is being utilized to reduce weight in Korea, its usefulness in obesity management has not been fully evaluated yet. The objective of this study is to evaluate the effect of Electro-acupuncture on thigh circumference. Methods: 12 healthy volunteers participated in this study. We measured the circumference of both thighs, and treated the thicker one with transcutaneous electro-acupuncture at 8 acupoints, 10 times in total. The electrical parameters were : 1st step frequency set was at 15Hz and the treatment proceeded for 50 minutes, 2nd step at 50Hz for 10 minutes and at 3rd step the acupunctures were removed and electrodes were attached on the lower limb at 166Hz for 15 minutes. In order to evaluate the effect of the treatment, total body weight, percentage of body fat and thigh circumference were measured 4 times. Before the treatment, after 5th and 10th treatment and 1 month after completion of the whole treating procedure. Statistical significance(P<0.05) was determined using the Wilcoxon signed rank test. We did not control diet, exercise and lifestyle of the volunteers. Results: No significant change was shown in body weight after 10 times of treatment. Yet the thigh circumference of effect group significantly decreased after 5th treatment and 10th treatment. The circumference of control group that was not treated by electro-acupuncture significantly decreased too. At first, difference between the two thighs in circumference was obvious, but no difference was left after 10 times of treatments on the thicker thigh. Percentage of body fat was significantly decreased. 1 month after having completed the treatment, there was no significant difference of body weight, thigh circumferences and percentage of body fat. Conclusion: These results suggest that electro-acupuncture effectively regulates regional fat, body fat percentage and body shape.

Objectives : The purpose of this research was to develop the magnetic acupuncture system which used solenoid coil for magnetizing acupuncture needle. The system could generate the meridian electric potential (MEP) similar to the potential by manual acupuncture. Thus, we tried to confirm the therapeutic effect that is caused by the MEP generation. Methods : To confirm the MEP, we stimulated the magnetic acupuncture with at 2Hz, $92.7{\pm}2mT$, PEMFs (Pulsed Electro-Magnetic Fields) at ST37 and measured the evoked potential between ST36 and ST41. Also, we conducted a fatigue recovery test using isokinetic exercise in order to identify the therapeutic effect on musculoskeletal disorders. We chose LR9 as a stimulation point. To observe the state of fatigue, we measured the EMG and analyzed median frequency and peak torque for 20minutes. Results : We observed that MEP which incurred from magnetic acupuncture was higher than he reported MEP induced by manual acupuncture. Moreover, its modes were divided into two types by the direction of magnetic flux. When generating magnetic flux in the direction of acupoint, the positive peak voltage of the MEP was generated. In contrast, negative peak voltage of the MEP was generated whenever meganetic flux generated in the outward direction. As a result of fatigue recovery, the median frequency (MF) of the magnetic acupuncture group were recovered faster than that of the non-stimulation group. However, the peak torques of both groups were not restored until after 20 minutes. Conclusions : We confirmed that the magnetic acupuncture system can lead to the MEP similar to manual acupuncture. Moreover, the MEP had a therapeutic effect on the musculoskeletal disorders.

The objective of tole study was to compare nutritional knowledge, attitudes and food practices of competitive athletes, recreational athletes and non-participants. All students enrolled at the University of Nebraska in an Introductory Nutrition course in which sports nutrition was stressed, were asked to participate in the study. The course was typical of many introductory nutrition courses ; about two thirds of the students were from the Department of Health, Physical Education and Recreation, and most of the students were encouraged to take this course by their advisers. The students were divided into three groups : 20 competitive athletes (mostly runners, swimmers, basketball players and football players for the University), 14 recreational athletes (who were involved in a planned exercise program at least 2 hours per week), and 19 non-participants. At the beginning of the semester, students completed a food frequency questionnaire, and a 24-hour food record based on the Food Guide Pyramid. A nutrition knowledge and attitude questionnaire was formulated specifically for this study, covering normal nutrition and sports nutrition. The results showed that consumption of foods from all Food Guide Pyramid food groups except the fats/oils/sweets group was not significantly different among the three student groups. Regarding the fats/oils/sweets group, competitive athletes consumed significantly more numbers of servings than recreational athletes, while the recreational athletes consumed significantly more than non-participants (p<0.01). The total mean scores from the nutrition attitude and knowledge questionnaire were not significantly different among the three student groups. However, combined athletes (competitive athletes and recreational athletes) obtained significantly higher scores on some of the nutrition attitude questions (p<0.05). The results of the study indicate that athletes, significantly lower scores on some of the nutrition knowledge questions (p<0.05). The results of the study indicate that athletes, whether competitive or some of the nutrition knowledge questions (p<0.05). The results of the study indicate that athletes, whether competitive or recreational, had a very positive attitude regarding the effects of nutrition on their sports performance and health: however, these athletes did not appear to apply scientific principles of sports nutrition to their diet. In conclusion, advising athletes to simply increase or decrease their intakes of certain foods is too simplistic an approach for maintenance of good health and for better sporting performance. Athletes and non-athletes need continuous nutrition education to help with improving their competitive edge and food choices.
