This study was carried out to provide information on the effect of nutrition education program for diabetic patients at the Guri City's Public Health Center. Subjects of this study were 31 persons(male 7, female 24) who attended all courses of "2002 Diabetes Education Class". They were indicated as the 'education group'(EG). Eating and living habits of EG were investigated before the education. EG's weight and blood glucose (post prandial 2 hours, PP2) were examined as well. EG's PP2 reduction was compared with a 'control group'(CG) who didn't join any course in that class. All of the subjects were non-insulin-dependent diabetes mellitus(NIDDM) patients. EG's average age was 62.4$\pm$8.8. Before taking the course, EG's PP2 was 251.5$\pm$29.6mg/dl, and body mass index(BMI) was 26.3$\pm$2.3 on average. Most of them were stressed out from their daily lives and usually had no exercise. Most people of EG ate meals rapidly and liked sweet and fatty foods. After the course of training, EG's weight and BMI before the training were not decreased significantly. However, all of the EG's PP2s, which were measured 4 times(before the meal at the special lunch session, after 2 hours at this meal, after 2 weeks and 4 weeks dietary assembly), were decreased in comparison with the PP2 which was checked prior to joining the training. EG's average PP2 was more reduced than CG's one. In addition, all groups' PP2s were decreased for 8 weeks. After all, this nutritional education at the public health center was effective in glycemic control for diabetes mellitus patients. Especially, when the dietary assembly as practical training was included in the educational process, the patient's dietary intake and PP2 was improved more effectively. Therefore, this study suggests that nutrition work at public health centers is necessary for the Health Promotion Policy.

In this paper, a new rehabilitation training system was developed to improve equilibrium sense by combining virtual reality technology with a fixed exercise bicycle. The subjects consisted of two groups. A group of young people, was compared against a group of elderly. We measured three different running modes of virtual bicycle system with two successive sets. The parameters measured were running time, velocity, the weight movement, the degree of the deviation from the road, and the variables about the center of pressure. The repeated training, our results showed that the running capability of the elderly improve compared. In addition, it was found out that the ability of postural control and the equilibrium sense was improved with the presentation of the visual feedback information of the distribution of weight. From the results of this experiment, we showed that our newly developed system might be useful in the diagnosis of equilibrium sense or in the improvement of the sense of sight and, somatic, and vestibular sense of the elderly in the field of rehabilitation training.

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.

The purpose of this study is to understand the principles of Balletfit and its program structure and to establish Balletfit's effects on body shape change and postural correction. Interview, the most commonly used method of qualitative research, was chosen as the research method. Ten Balletfit class participants, who have attended private lessons twice per week, for three to six months period of time, were selected. These participants were chosen from participants of private lessons instead of group lessons for in-depth insights. The research was limited to a small group of participants and therefore, it is difficult to standardize the result. Also, because this study is based on the opinions of the participants, not by a posture measuring device, the accuracy of the result is limited as well. The followings are the conclusion of this research. First, the participation motive was either internet research or acquaintance's recommendation. Secondly, the effort to change the body shape. After experiencing Balletfit classes, the participants became aware of their body and made an effort to recover their posture by holding the stomach tight and sitting up correctly. Thirdly, their posture became ideal. Most participants became aware of what an ideal posture is and as their body became ideal, the participants also recovered their health by becoming aware of their inner and outer body. Lastly, they tend to prefer beautiful body line. After the experience, all participants became interested in the body line and preferred to build a beautiful body line with correct postures. The most significant effect of Balletfit was the body line. Therefore, the experience of Balletfit develops the inner and outer body awareness and also can be consider to effect the change of the body shape. Balletfit will become a satisfying exercise for modern people, who desire a beautiful, healthy body.

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.

This study investigated the relationship among gait variables and physical fitness variables for Korean elderly people. Two hundred elderly people aged 65 to 85, (100 men and 100 women) participated in this study. They performed senior fitness test consisting of 6 tests, 3 additional physical tests (vertical jump, one leg stand, and grip force), body composition measures, and gait test. The gait test used shoes having an inertia measurement device in the outer-soles. The results indicated that the stride length, 6-min walking, lean body mass, and dumbbell curls were significantly affected by age (the above 75 group vs. the below 75 group). Among 33 measured parameters, the principal component analysis (PCA) revealed five PCs such as gait characteristics, physical features, gait variability, and fitness levels. In addition, the correlation analysis showed that the preferred walking speed was significantly, positively associated with stride length and single support time, whereas it was negatively associated with double support time and gait variability.(Ed note: please confirm my modification) In conclusion, sarcopenia should be avoided in elderly people, and resistance exercise is highly recommended to help elderly people maintain their gait ability.

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.

This study used an S-180 cell-injected mouse model to evaluate the antitumor effects of the acute and subacute toxicity of Keumsa (Phellinus linteus) extract intravenously administrated in ICR mice. When administered intravenously (31.3-250 mg/kg body weight), Keumsa (Phellinus linteus) extract significantly inhibited the growth of the solid tumor cell. The antitumor activity of Keumsa (Phellinus linteus) extract increased in a dose-dependent manner. The highest dose (250 mg/kg body weight) was highly effective, reducing tumor formation by 42.7% compared with the control group. In the acute toxicity test, $LD_{50}$ of the Keumsa (Phellinus linteus) extract showed 632.84 mg/kg (♂) and 814.48 mg/kg (♀) after intravenous administration. In addition, liver and spleen weight were increased in a dose-dependent manner. In the subacute toxicity test, the mice were intravenously administered over the course of 28 days. The $LD_{50}$ of the Keumsa (Phellinus linteus) extract showed 355.41 mg/kg (♂) and 383.53 mg/kg (♀) after intravenous administration. The liver and spleen weight also increased in a dose-dependent manner. In the case of the group that received more than 125 mg/kg of intravenous administration, exercise capacity, such as jumping ability and agility, were significantly increased. These results suggest that Keumsa (Phellinus linteus) extract can be regarded as a potent enhancer of the innate immune response, and it can be considered as a new natural product with low toxicity that may be used as a candidate for antitumor action.
