  • Purpose : This study is to offer clinical primary data that examines the change of imaging structure and the quantitative evaluation of muscle activity on myofascial trigger points. This study examines neuromuscular physiological characteristic by comparing the differences in physical findings, pressure pain threshold, imaging, and electrophysiological characteristics in latent and active myofascial trigger points muscle and normal muscle through the following experimental procedures. Methods : The participants for the study were thirty-three adults in their twenties. We divided three groups into normal, latent and active myofascial trigger points groups by physical findings. We analyzed the results of measured pressure pain, threshold for pain, ultrasound imaging perform for structure characteristic of muscle, surface EMG according to type of muscle contraction for function of muscle contraction. Results : Significant differences were indicated in pressure pain threshold (p<0.05). Significant differences were discovered in the ultrasound imaging analysis. There were increases in muscle Echogenicity white area index (p<0.001). There were significant differences that decrease in %MVIC (p<0.05), increase in MDF (p<0.05). Conclusion : From these results, active rnyotascial trigger points muscle showed quality deterioration on ultrasound imaging and decreased function of muscle contraction, increased motor unit action potential of II type fiber, and electrophysiologically. Imaging structure and neuromuscular physiological characteristic can be diagnostic and quantitative analytical techniques for myofascial pain syndrome and a primary factor that reflected in physical therapy intervention.

  • While sludge is settling in batch column, sludge concentration becomes high. Because the characteristic of sludge settling changes in function of time due to the sludge concentration change, the sludge settling velocity changes too. Also, because the sludge settling characteristic is influenced by a physical characteristic of sludge and a column height etc, it is difficult to exactly measure the sludge settling characteristic. Although the sludge volume indexes, SVI, SSVI and $SSVI_{3.5}$, are used to predict sludge settling characteristic, these indexes are not reliable values. Because the previously established models for sludge settling velocity predict the sludge settling velocity only, it is difficult to predict sluge-water interface height by using those models. The purpose of this experiment is to establish the empirical model which predicts the sludge interface height change with respect to the sludge physical characteristic and the settling condition.

  • In this paper, we proposed noninvasive and continous measurement of blood pressure using pulse transit time(PTT) and physical characteristic parameters and verified its clinical effectiveness. PTT can be obtained by electrocardiogram and phtoplethysmogram. There are many researches for estimating blood pressure using PTT which can be used for individual. However, it is not enough for extracting general regression equation which can estimate blood pressure for unspecified people. In this study, we suggested the regression equatin using PTT and physical characteristic parameters related to blood pressure and did measure blood pressure of many people. we compared the performance between two methods. As the results, we knew that the regressin model using PTT combined with physical characteristic parameters can estimate blood pressure more acurately and is closer to American National Standards Institute of the Association of the Advancement of Medical Instrument(ANSI/AAMI).

  • This study is concerned with the establishment of the characteristic equation of a combined system consisting of a cantilever beam with a tip mass and an in-span visco-elastic helical spring-mass, considering the mass of the helical spring. After obtaining the "exact" characteristic equation of the combined system, by making use of a boundary value problem formulation, the characteristic equation is established via a transfer matrix method, as well. Further, the characteristic equation of a reduced system is obtained as a special case. Then, the characteristic equations are numerically solved for various combinations of the physical parameters. Further, comparison of the results with the massless spring case and the case in which the spring mass is partially considered, reveals the fact that neglecting or considering the mass of the spring partially can cause considerable errors for some combinations of the physical parameters of the system.

  • This study was performed to investigate the characteristic of physical touch in caring situation. The subjects of this study were adults in caring situation, therefore they were composed of 7 patients, 6 nurses, 3 doctors, 3 pharmacologists, 3 men in paramedicine area, 3 nursing educators and 13 normal general adults. The datas were gathered through nonstructured questionaire from June, 20th to September, 15th in 1995. The datas were subjects' descriptions about the intention, perception, and form of physical touch in caring situation and analysed by content analysis. The results as follow : The datas were divided into four areas. There were the situation being necessiated the physical touch, meaning of physical touch, form of physical touch and perception about physical touch in caring situation. The situation being necessiated physical touch were the situation that required physical treatment, to deliver the active expression of concern about the patients, to determine the treatment due to the identification of physical condition of patients and to induce the psychological eqilibrium into patient's mind. The meanings of physical touch in caring situation were - Good meanings that intention is to encourage, to be have hope about health and to deliver the affection willing to help patient. - therapeutic methods that were to facillitate the circulation of blood, to reduce the pain perception and to facillitate the circulation of qi. - interpersonal affectionate relation that the intentions were to deliver the understanding of patient's pain, were to delivery the meaning to the patient not be alone. The forms of physical touch in caring situation were none invasive forms just like laying hands on hand, head, shoulder, gentle knocking on the shoulder or back, massage of legs and back and finger pressure on acupuncture points. The perception of physical touch in caring situation divided into two parts. In family, the perceptions of physical touch in caring situation were to promote health status because physical touch induce the psychological peace, and to evoke the importance of relationship among family members. In relation with care giver, perception of physical touch in caring situation were inevitable process in treatment, and to deliver the trust and concern about patients.

  • Purpose : This epidemiological research was conducted to investigate the relationship between the groups of TMD and the behavioral, psychological, and physical symptoms through RDC/TMD. Subjects and Methods : The subjects of this research were the 286 patients who had visited Seoul National University Bundang Hospital; their common chief complaint was temporomandibular discomfort. The mean age of the patients was 32.9 from 11 to 85, and the number of men and women was 67 and 219, respectively. The patients were examined through clinical and radiological methods and diagnosed by 1 investigator. They were divided into 3 groups: myogenous group (group 1), arthrogenous group (group 2), and combined group (group 3). The behavioral, psychological, and physical symptoms were evaluated through questionnaires on RDC/TMD. Specific items were selected to calculate the graded chronic pain (characteristic pain intensity, disability points), jaw disability, depression, and non-specific physical symptoms (pain items included/excluded) in the questionnaire. One-way ANOVA, Kruskal-Wallis test, and chi-square test were applied as statistical methods. Results : As a result of classifying temporomandibular disorder in this study, the patients were distributed as follows: 9.1% of group 1, 79.7% of group 2, and 11.2% of group 3. In the analysis of graded chronic pain (characteristic pain intensity, disability points), jaw disability, and non-specific physical symptoms (pain items included/excluded), group 3 had the highest score, and the difference was significant (p<0.001). Moreover, the depression score of group 3 was significantly higher than groups 1 and 2 (p<0.05). Note that that the second order of jaw disability score was group 2, on the other hand, those of the other groups were group 1. Conclusion : Myofascial pain could be assumed to be related closely to the behavioral, psychological, and physical symptoms except jaw disability compared to joint pain through RDC/TMD.
