Purpose: The objective of this study was to offer primary clinical data examining whether change of imaging structure and quantitative evaluation of muscle activity on myofascial trigger points can lead to implementation of an analytical technique for evaluation of myofascial pain diagnoses. In addition, we examined the effect of a variety of mediation techniques, in order to examine neuromuscular physiological characteristics of myofascial trigger points muscle by comparing differences in pressure pain threshold and ultrasound imaging. Methods: Participants in the study included 30 adults in their twenties. The subjects were divided into the normal and myofascial trigger points groups. Clinical outcomes were evaluated by pressure pain threshold for pain and ultrasound imaging was performed for evaluation of the structural characteristics of muscle. Independent t-test was used for statistical analysis. Results: The two groups showed statistical significance in the change in pressure pain threshold (p<0.05). Findings of ultrasound imaging analysis showed no significant differences, increased muscle thickness was observed (p>0.05). Findings of ultrasound imaging analysis showed significant differences, increased muscle echodensity was observed (p<0.05). Findings on ultrasound imaging analysis showed significant differences, increased muscle white area index was observed (p<0.05). Conclusion: From these results, active myofascial trigger points muscle showed quality deterioration on ultrasound imaging. Thorough evaluation of imaging structure and physiological characteristics can be useful quantitative analytical techniques for diagnosis of myofascial pain syndrome and a primary factor reflected in physical therapy intervention.

The purpose of this study was to determine the effect of transcutaneous electrical nerve stimulation(TENS) on the alteration of pressure pain threshold of myofascial trigger points. We used fifty nine patients with upper trapezius mayofascial pain syndrome. Participants classified according to each group in conventional TENS(high rate, low intensity) and acupuncture like TENS(low rate, high intensity). The test was measured continuously pre test, post-test by algometer. The following results were obtained; 1. Pressure pain threshold were significantly increased in all groups(p<.001). 2. In comparison between groups, pressure pain threshold were not significantly differenced. These results lead us to the conclusion that each method by TENS were significantly increased pressure pain threshold of upper trapezius trigger points. Therefore, a further direction of this study will be to provide more evidence that TENS method have an effect on pressure pain threshold of myofascial trigger points.

Objectives: Many acupuncture points have been suggested for the treatment of Bell's palsy, but information on which acupuncture points are more important in treatment is not provided. This study was conducted to investigate the importance of acupuncture points currently used clinically in Bell's palsy. Methods: By reviewing the full text of 11 books that recorded acupuncture prescriptions from the Qin Dynasty to the Qing Dynasty, the frequency of use of acupuncture points, their meridians, and their location were investigated. Results: The average number of acupuncture points used for local, adjacent and distal points selection was 10.5, 2, 4 respectively. The number of acupuncture points increased from the Qin Dynasty to the Ming Dynasty 《Bojaebang》 and then decreased, but the proportion of local points has been still high. From the Ming Dynasty, ST4, ST6, GV26, and GV24 were mainly have been used as the local points. Except for the GB12, the use of the rest of the acupuncture points gradually decreased in the adjacent points. In the distal acupuncture points, it was summarized to point of lung and large intestine channel until the Ming Dynasty, and LI4 was mainly used in the Qing Dynasty. Yangming meridian has been most often used at the local and distal area except for the adjacent area. Conclusions: In the treatment of facial paralysis, the lower part of the face had the highest proportion among local acupuncture points, and the Yangming had the highest proportion by meridian.

This study conducted a survey with the 67 students who are in their 2nd year at 3 vocational high schools. The researcher of this study developed and operated the smoking cessation program based on the Transtheoretical model. To evaluate the effects, experiments were repeatedly done. The data were collected from June 21, 2004 till July 9, 2004. The survey was done based on the questionnaire-interview before and after education. The collected date was computerized by using SPSS-WIN 10.0 program. The results are as follows: Firstly. before education, the smoking cessation stage of change shows precontemplation stage $37.3\%$, preparation stage $37.3\%$, and contemplation stage $25.4\%$ respectively. However, after education it shows preparation stage $44.8\%$, action stage $25.4\%$, contemplation stage $19.4\%$, precontemplation stage $10.4\%$. The positive result was $62.7\%$ and smoking cessation stage of change made a 0.9 step increase. Secondly, process of change rose in all the areas except helping relationship. It also shows statistical improvement in all the fields except the dramatic relief of the experiential process, the helping relationship of behavioral process and stimulus control Thirdly, negative affective situation temptation, positive social situation temptation, and habitual strength temptation's average points decreased but showed statistical differences. Weight control temptation's average points decreased after education but didn't show statistical differences. Self efficiency increased measurably after education. Fourthly, concerning the social pros and coping pros caused by smoking, the average points were low after education and showed statistic decrease. As for the cons due to smoking, the average points increased but didn't show any statistical differences. In conclusion, thanks to the smoking cessation program applied by the Transtheoretical model, the smoking rate of vocational high school students became low and their smoking temptation also dropped considerably. In conclusion, while the pros for smoking were lessened, its corns were heightened through the educational awareness offered by this program.

Purpose: With a view to providing basic data to develop cardiopulmonary resuscitation education suitable for elementary students, the cardiopulmonary resuscitation education was conducted to grasp students' knowledge, skills accuracy and the attitude change before and after the education. Methods: Convenience sampling was made on fourth and fifth graders(total-35 students) of S elementary school located in K city, Chungcheongnam-do, and this was a pre-experiment research designed before and after choosing a single group. In terms of methods, specifically we, researchers ; 1) Handed out questionnaires to students directly to make them fill in firsthand and collected the questionnaires. 2) Utilized PPT materials based on 2005 AHA guideline and DVD materials of AHA, to give students theoretical education of cardiopulmonary resuscitation. We used Anne/SkillReporter$^{(R)}$ torso produced by Leardal Inc, and Little Anne to conduct practical education individually. 3) Asked students to give Anne/SkillReporter$^{(R)}$ torso cardiopulmonary resuscitation five times with the ratio of 30 : 2, and then one of researchers filled in the evaluation sheet individually. 4) Evaluated the accuracy of students' ability to perform the resuscitation based on the record of Anne/SkillReporter$^{(R)}$ integrated printer(which was the objective tool to grasp students' skills accuracy). 5) Gave out questionnaires to make students fill them in and then collected them. after completing the practical evaluation. Results: 1) In case of the attitude about cardiopulmonary resuscitation, Students' confidency rose from 19.28%(before the education) to 93.57(after the education)- which is a positive change. 2) As the result of the education, some elementary students scored 11 points (full score-16 points), up from 5 points before the education, in terms of the knowledge about cardiopulmonary resuscitation. The average point also reached 13.14 points(after the education), jump from 8.37(before the education), which was the rise of 29.8%. 3) When it comes to the practical performance, the skills accuracy was 80.93% on average, and the calculation method was as follows: total items were 16, and each item was marked form 0 to 2 points, meaning the full score was 32 points. The minimum score was 19 points and the maximum was 32($M{\pm}SD=25.90{\pm}2.88$), which was calculated based on percentage. 4) Regarding skills accuracy, respiration accuracy(%)($M{\pm}SD=30.20{\pm}27.16$) was higher than pressure accuracy(%) ($M{\pm}SD=15.34{\pm}25.27$). Conclusion: The result showed that students' attitude on cardiopulmonary resuscitation changed positively. and meaningful difference(p = .00) existed in the change of students' knowledge. In terms of skills accuracy. chest compression and airway control showed high accuracy, but the result of Anne/SkillReporter$^{(R)}$ performance showed that the accuracy of chest compression was lower than that of mouth-to-mouth resuscitation.

This study is intended to look into the effects of children's forest experience activities on parent-child relationship and child attitude change. To achieve this, a survey was empirically carried out to 185 children. The results were as follows. First, the normality of parent-child relationship before and after forest experience activities showed that the parent-child relationship increased from 3.229 points before participation in forest experience activities to 3.841 points after participation in forest experience activities on average. And the child attitude increased from 3.226 points before participation in forest experience activities to 3.765 points after participation in forest experience activities, which there was a change of mean value before and after forest experience activities in both concepts. Second, the difference in parent-child relationship and child attitude change before and after forest experience activities showed that both parent-child relationship(Z=-10.98, p<.001) and child attitude(Z=-11.05, p<.001) did have significant differences before and after forest experience activities in the significant level of .05. As for the above-mentioned findings, children's forest experience activities improves the parent-child relationship and changes their behaviors outside the kindergarten. Consequently, nature-friendly forest experience education can provide emotional stability for children and help them build a positive rapport between teacher, parent and peer.

Change point analysis is a efficient tool to understand the fundamental information in hydro-meteorological data such as rainfall, discharge, temperature etc. Especially, this fundamental information to change points to future rainfall data identified by reasonable detection skills can affect the prediction of flood and drought occurrence because well detected change points provide a key to resolve the non-stationary or inhomogeneous problem by climate change. Therefore, in this study, the comparative study to assess the performance of the 3 change point detection skills, cumulative sum (CUSUM) method, Bayesian change point (BCP) method, and segmentation by dynamic programming (DP) was performed. After assessment of the performance of the proposed detection skills using the 3 types of the synthetic series, the 2 reasonable detection skills were applied to the observed and future rainfall data at the 5 rainfall gauges in South Korea. Finally, it was suggested that BCP (with 0.9 posterior probability) could be best detection skill and DP could be reasonably recommended through the comparative study. Also it was suggested that BCP (with 0.9 posterior probability) and DP detection skills to find some change points could be reasonable at the North-eastern part in South Korea. In future, the results in this study can be efficiently used to resolve the non-stationary problems in hydrological modeling considering inhomogeneity or nonstationarity.

The purpose of this study is to find out what effects aerobic exercises and acupuncture point stimuli have on the blood. For this purpose, we reviewed 10 papers on aerobic exercises and 10 papers on the stimuli to acupuncture points and compared the changes of HDL-C, seroenzyme GOT and GPT. The results showed that HDL-C increased significantly after aerobic exercises; more so than before as stated in the papers on aerobic exercises. On the other hand, HDL-C decreased significantly after acupuncture point stimuli; more so than before as stated in the papers on the stimuli to acupuncture points. Seroenzyme GOT increased more significantly after aerobic exercises than shown before in the papers on aerobic exercises. However, there was a more significant decrease after the stimulus than shown before in the papers on acupuncture points stimuli. Seroenzyme GPT increased more significantly after aerobic exercises than shown before in the papers on aerobic exercises. There were no significant differences before and after on, the acupuncture points stimuli, according to those papers. Therefore, as HDL-C increased significantly when doing aerobic exercises, aerobic exercises prove to be a more effective treatment method than stimuli to the acupuncture points for patients with hyperlipidemia. However, from the facts that seroenzyme GOT and GPT increased significantly after aerobic exercises, we find that aerobic exercises may be more of a burden on the tissues of the liver, skeletal muscles, stomach, etc. than the stimuli to acupuncture points.

Active contour model or snake is widely used for segmentation method in the area of the image processing and computer vision. The main problem in the active contour model is that results are very dependent to the closet points of the numbers and the location in initial step. Especially, in case of balloon-like active contour model, the small region which consist of intial closet points are expanded until the edge is reached. It is a serious problem because the considered region are huge with limited points. To solve this problem, in this paper, we propose the method that the number of closet points could be change based on the distance between points.
