The couple force of the scapular stabilizers for upward rotation that include the upper and lower trapezius, serratus anterior muscles is essential to maintain the stability of shoulder joint. But if there is an imbalance of these muscles, it would occur many problems of shoulder joint. A push-up plus exercise with an unstable support is used in order to increase the muscle activity and stimulate the proprioception of shoulder joint. The purpose of this study was to compare the muscle activity of upper and lower trapezius, serratus anterior muscles and to determine which exercise is more effective when subjects perform push-up plus exercise in the stable support and unstable support. 15 healthy subjects and 15 painful subjects with injury of shoulder joint participated in this study. Surface electromyography data were collected during plus phase of push-up plus exercise. The types of push-up plus exercise were composed of three conditions. Stable type is subjects performed the push-up plus exercise on the fixed support and unstable type 1 is on the sling without shaking and unstable type 2 is on the sling with shaking by tester's manual. The upper and lower trapezius activities of injured group were higher than uninjured group at three measure conditions, but serratus anterior activities were not. The UT/SA ratio of injured group was higher than uninjured group at three measure conditions. The serratus anterior activities were most high at unstable 2 measure in both groups. The UT/SA ratio was most low at unstable 2 measure condition in injured group only. The present result revealed that push-up plus exercise in the unstable support with shaking which took most high serratus anterior activities and most low of UT/SA ratio is optimal cure method that can improve the imbalance of the scapular stabilizer.

The levels of psychosocial stresses of dental hygienist were analyzed to reveal the various factors related to them. The self-administered questionnaires were performed, to 276 dental hygienist in Daejeon City. Univariate analysis and multiple regression were performed with survey results, in which a degree of psychosocial stress was dependent variable and others were independent variable. 1. In terms of various levels of psychosocial stress according to the higher level of stress was found in the group of lower age, unmarried, and without spare times for hobby activities, the group with shorter-term job career, lower salary, and stress was found in the group who think that their job is considered as low position or their job is not high position in society or their prospect about job is discouraging, the group without regularly exercise, without regularly eating habits, in the group with higher level of job demand, lower job autonomy, and lower social support from colleagues in work than their respective counterparts. 2. Concerning correlation between psychosocial stress and various factors, while level of stress was negatively correlated with age, job career, salary, socioeconomic status of oneself, socioeconomic status of dental hygienist, future status of dental hygienist, job autonomy, social support from superiors, social support from colleagues, social support, but it was positively correlated with job demand. 3. Multiple regression revealed that the factors which influence on psychosocial stress included hobby activities, sleeping hours, job demand, which has explanatory powers of 29.9%. Therefore, to reduce of stress of dental hygienists, it is required to develop an effective strategy that institutional support for improvement of job environments and research for them be revitalized.

In this research, we propose a hybrid group decision support mechanism (H-GDSM) based on Fuzzy AHP (Analytic Hierarchy Process) and FCM (Fuzzy Cognitive Map). The AHP elicits a corresponding priority vector interpreting the preferred information among the decision makers. Corresponding vector was composed of the pairwise comparison values of a set of objects. Since pairwise comparison values are the judgments obtained from an appropriate semantic scale. However, AHP couldn't represent the causal relationship among information, which were used by decision makers. In contrast to AHP, FCM could represent the causal relationship among variables or information. Therefore, FCMs were successfully developed and used in several ill-structured domains, such as strategic decision-making, policy making, and simulations. Nonetheless, many researchers used subjective and voluntary inputs to simulate the FCM. As a result of subjective inputs, it couldn't avoid the rebukes of businessman. To overcome these limitations, we incorporated the Fuzzy membership functions, AHP and FCM into a H-GDSM. In contrast to current AHP methods and FCMs, the H-GDSM method developed herein could concurrently tackle the pairwise comparison involving causal relationships under a group decision-making environment. The strengths and contributions of our mechanism were 1) handling of qualitative knowledge and causal relationships, 2) extraction of objective input value to simulate the FCM, 3) multi-phase group decision support based on H-GDSM. To validate our proposed mechanism we developed a simple prototype system to support negotiation-based decisions in electronic commerce (EC).

Objective: In the present study, the effects of progressive body weight support treadmill forward & backward walking training (FBWT), progressive body weight support treadmill forward walking training (FWT), and progressive body weight support treadmill backward walking training (BWT), and on stroke patients' ambulatory abilities were examined. Design: Randomized controlled trial. Methods: A total of 36 chronic stroke patients were divided into three groups with 12 subjects in each group. Each of the groups performed one of the progressive body weight supported treadmill training methods for 30 minute, six times per week for three weeks, and then received general physical therapy without any other intervention until the follow-up tests. For the assessment of the step length, total double support, cadence, gait were measured using optogait and the 10-m walk test (10MWT), 6 minutes walk test (6MWT). Results: In the within group comparisons, all the three groups showed significant differences between before and after the intervention (p<0.05). In the comparison of the three groups, there were significant differences among the three groups in stride length, double limb support stance, cadence, 10MWT, and 6MWT in the third week, and only in stride length, 10MWT, and 6MWT test in the sixth week (p<0.05). Conclusions: This study verified that progressive body weight-supported treadmill gait training positively affected the gait ability of stroke patients in an actual gait environment. It also showed that FBWT group was more effective than FWT group and BWT group training.

Purpose The purpose of this study was to investigate the change of balance ability by performing closed chain exercise on stable support surface and unstable support surface in twenties. Methods This study randomly selected 15 students in the closed chain exercise group on the stable support side and 15 on the closed chain exercise group on the unstable support side. Balance ability was measured before and after the start of exercise and static balance was measured by OLT(One Leg Standing Test) and FRT (Functional Reach Test). Result The changes of the function reach test of the closed chain movement according to the ground type were significant in the unstable and stable support surfaces and the change of function reach test after the intervention in the two groups was significantly improved compared with the closed chain movement respectively. The one leg standing test changes of the closed chain movement according to the ground type showed significant results on the unstable and stable support surfaces, but there was no significant difference in the one leg standing test changes after intervention between the two groups. Conclusion The effect of closed chain training on ground type is unstable. The change of function reach test and one leg standing test of the closed chain exercise group on the stable support surface resulted in significant changes after exercise, but there was a significant difference in the balance ability of function reach test change after intervention between the groups.
