Purpose : The purpose of this study is to investigate the effect of each lower trapezius muscle exercise performed according to the abduction position (Y type - shoulder joint abduction 145 °, T type - shoulder joint abduction 90 °, and MPC type - shoulder joint 45 ° abduction) of the shoulder joint on the muscle activity of the round shoulder and lower trapezius muscle. Methods : This study was conducted on 31 adult men and women. Through random assignment, they were assigned to the Y group, T group, and MPC group. A 4-week intervention was performed for each group of 31 subjects who participated in the experiment, and shoulder height and lower trapezius muscle activity were measured before and after the intervention. Shoulder height measurement is a test to measure rounded shoulder posture. When the value is low, it means that rounded shoulder posture is improved. The muscle activity of the lower trapezius muscle was measured using the %MVIC method, and when the value is high, it means that the lower trapezius muscle is active. All measured data were verified using dependent t-tests for before and after comparisons and one-way analysis of variance for comparisons between groups. Results : The results of this study showed a significant decrease after intervention only in shoulder height. Muscle activity of the lower trapezius muscle decreased after intervention, but did not show a significant difference. Both variables showed no significant differences between groups. Conclusion : The results of this study show that three lower trapezius muscle exercises were performed on subjects in rounded shoulder posture. All three groups showed a significant decrease in the shoulder height value, a method of measuring rounded shoulder posture, and no significant differences between groups could be confirmed. Therefore, all three exercises can be considered effective in reducing shoulder posture.

Vertigo is one of the most common complaints encountered by physicians and the patients are steadily increasing. These patients are exposed to the risk of secondary accidents such as falls due to vertigo. There are two ways to improve this symptom: medication and rehabilitation. Although temporary symptomatic improvement may be expected in patients treated with medication, vertigo may recur and medication can delay central compensation. In contrast vestibular rehabilitation exploits central mechanisms of neuroplasticity to increase postural stability and enhance visual-vestibular interactions in situations that generate conflicting sensory information. However, vestibular rehabilitation may be compromised by incorrect performance of exercises, and there is a need for active effort and interest from the patient during rehabilitation. To solve these problems, we decided to apply FOVE HMD for eye-tracking and Unity3D to create virtual reality. The proposed eye-tracking based algorithm calculates the concentration of users with eye tracking data and calculates the motion width of the patient with nystagmus, thus the severity of the patient according to the score can be determined. According to our experimental test against healty group and patients group, this result showed the meaningful data to use define the contents result.

Purpose : We investigated the effects of horseback riding and horseback riding machine exercise on the serum lipid profile in elderly individuals. Methods : Our study included 30 healthy elderly individuals who were randomly assigned to 2 groups: the horseback riding and the horseback riding machine exercise group, with each group comprising 15 individuals. The riding exercise program was performed 25 times a week over 12 weeks. The repeated measures analysis of variance was used to determine changes in serum lipid profiles before and after exercise 6 and 12 weeks after exercise. Results : An intergroup comparison of blood tests showed that triglyceride, total cholesterol and low-density lipoprotein-C levels were decreased in both groups after 12 weeks of the riding exercise program. However, both groups showed an increase in high-density lipoprotein-C levels, although this difference was not statistically significant. Conclusion : Horseback riding and horseback riding machine exercise showed a positive effect on the serum lipid profile in elderly individuals.

This paper presents the damage assessment of a free-fall dropped object on the seabed. The damage to a dropped object totally depends on the relationship between the impact energy and the soil strength at the mudline. In this study, unexpected dropping scenarios were first assumed by varying the relevant range of the impact velocity, structure geometry at the moment of impact, and soil strength profile along the penetration depth. Theoretical damage assessments were then undertaken for a free-fall dropping event with a fixed final embedment depth for the structure. This paper also describes the results of a three-dimensional large deformation finite element analysis undertaken for the purpose of validation. The analyses were carried out using the coupled Eulerian-Lagrangian approach, modifying the simple elastic-perfectly plastic Tresca soil model. The validation exercises for each dropping scenario showed good agreement, and the present numerical approach was capable of predicting the behavior of a free-fall dropped object.

Purpose: The purpose of this study was to determine the effects of a Health Maintenance Program on physical functions and mental health of the elderly in nursing homes. Method: Sixty elderly(over 65 years old) in a randomized control study participated in a 16-week group-based intervention including functional exercises and health education. The participants were divided into 3 groups(Health Maintenance Program Group, Supportive Music Exercise Group, and Control Group) of 20 elderly each. Data was collected from Dec. 1st, 2005 to Mar, 30th, 2006. Physical function of lower body strength was assessed using a 30-second chair test, flexibility was assessed using a sit-and-reach test, and static balance was assessed by the ability to balance on one leg with open and closed eyes. Depression was assessed using the Korean Form of the Geriatric Depression Scale and self esteem was assessed using Rosenberg's Self Esteem Questionnaire. Data was analyzed by Chi-square test, One-way ANOVA, and Repeated measure two factor analysis. Results: A Health Maintenance Program significantly increased muscle strength, flexibility and static balance, but depression and self-esteem scores were not significantly changed. Conclusion: Findings demonstrated that a Health Maintenance Program was more effective on physical function than mental health of the elderly in nursing homes.

Purpose : The purpose of this study was to identify the effect of lumbar stabilization exercise (LSE) and isometric lumbar strengthening exercise (ILSE) on lumbar strength and lumbar extension range in healthy young adults. Method : Ten healthy young adults (six males and four females) volunteered to carry out the LSE and ILSE program for two weeks. The subjects were randomly allocated to two groups: the LSE group (n=5) and the LSE plus ILSE group (n=5). The LSE consisted of 20 minutes of exercise related to lumbar stabilization, and the ILSE was composed of five minutes of isometric stabilization exercise with a specific device. Each group exercised three times per week for two weeks. Assessment tools were made using the subjects' isometric lumbar strength and lumbar extension range before and after the interventions. Results : Statistical analysis revealed significant differences in isometric lumbar strength and the lumbar extension range between before and after the interventions in each group (p<.05). Also, the lumbar extension range improved significantly in the LSE plus ILSE group compared to the LSE group; however, there was no statistically significant difference in the two groups' isometric lumbar strength (p>.05). Conclusion : The findings suggest that ILSE might be feasible in clinical settings by offering benefits for lumbar function. Future studies will be continued.
