This study suggests a structural design process for the upper control arm installed at a vehicle. Static strength and durability are the most important responses in the structural design of a control arm. This study considers the static strength in the optimization process. The inertia relief method for FE analysis is utilized to simulate the static loading conditions. According to the classification of structural optimization, the structural design of a control arm is included in the category of shape optimization. In this study, the metamodel technique using the kriging method is adopted to obtain the minimum weight satisfying the strength constraint. Then, the final design is suggested by considering the durability criteria. The durability assessment is obtained by the index of fatigue durability called the SWT (Smith-Watson-Topper) index. The final optimum shape has been proposed by trial and error method.

The purpose of this study is to analyze psychological and physiological effects accordance with viewing and walking in the forest and urban area. In the result of measurement of physiological reactions in nervous system, viewing of the forest had a calming effect on the nervous system by reducing blood pressure and heart rate. The other hand, viewing and walking in the urban area compared to the forest area raised stress by increasing blood pressure and heart rate. In addition, viewing in forest area was effective in stress relief by noticeable reduction of the amylase concentration. In contrast, walking in the urban area was also confirmed an increase of stress by increasing the concentration of the amylase. A viewing and walking in forest area was effective in alleviating depressed on anxiety, anger, fatigue and confusion.

Purpose : The purpose of this study was carried out to review for hydrotherapy, phototherapy, cupping therapy, therapeutic touch and massage as a Korean traditional physical therapy. Methods : This is literature study with books, and thesis. Results : The physical therapy that is in use nowadays has been around since human being started to live on the earth. In primitive times, when men were injured while hunting, they washed the wound in clinic water and dried it out in the sunshine, they also soaked their bodies in hot springs to decrease physical fatigue, Heating of injured tissue has been used for centuries for pain relief and muscle spasm. Conclusion : Korean traditional physical therapy has been developed and its scientific effects has been proven, It is required, to continue to carry out studying on this field.

An exhaust brake system is composed of a gate valve, a pneumatic cylinder and an on-off solenoid valve. An on-off solenoid valve which is a key component of the exhaust brake system ought to have characteristics such as high reliability and long life for reducing the foot brake and tires damage, and for driver's fatigue relief of middle/large size vehicles running a long distance. In this paper, an on-off solenoid valve which is used for vehicle brake system was studied. For the performance evaluation of the on-off solenoid, electromagnetic characteristics and dynamic characteristics are analyzed. On the basic study for the performance improvement of exhaust brake system, pneumatic circuit and pneumatic valve of on-off solenoid type were suggested and the performance of pneumatic valve through the test procedure was evaluated.

This study is to determine the effects of BUDDEUMI(moxibustion and cupping a boli) therapy on the relief of shoulder pain among middle aged women. methods : A total of 39 middle aged women with shoulder pain are selected : 20 in the experimental group and 19 in the control group. The data was collected by using questionnaires. The BUDDEUMI(moxibustion and cupping a boli) therapy on the should and back was administered to the experimental group, and no treatment was given to the control group. All of the subjects were examined on a subjective symptom scale and on the grade of discomfort and pain in everyday life as developed by Japan's Industrial Fatigue Research Committee of the Industrial Hygienics Society(1988), Sohn, Mong Ho(1999), Visual Analogue Scale as developed by Cline (1992). SPSS/win 12.0 was used for Date analysis, General features demonstrated by frequency number and percentage. The effects of the BUDDEUMI(moxibustion and cupping a boli) therapy was analyzed by a t-test. The homogeneity testing revealed that all study variables are equally distributed between experimental and control groups. The hypothesis, 'the experimental group who received BUDDEUMI(moxibustion and cupping a boli) therapy will decrease in the grade of discomfort of shoulder', is supported. The hypothesis, 'the experimental group who received BUDDEUMI(moxibustion and cupping a boli) therapy will decrease in the Visual Analogue Scale is supported. Conclusion : As a result of this study, BUDDEUMI(moxibustion and cupping a boli) therapy will be able to be used as the self care therapy to improve the symptoms of middle aged women who has the shoulder pain.

Objectives The purpose of this study was to evaluate the most effective stimulating electrode in Microcurrent electrical neuromuscular stimulation (MENS) for pain relief, and to apply to the treatment of Delayed onset muscle soreness (DOMS). Methods We included 45 participants who met the inclusion criteria. DOMS of both Triceps Surae Muscles were experimentally induced through eccentric contractions. 24-hours after induction of DOMS, who scored more than 40 mm in visual analogue scale (VAS) were randomly assigned into three groups (n=44). In 15 of them, needle electrodes were inserted into BL57, BL56. In 15 of them, surface electrodes were applied on the same points and the others were treated with manual acupuncture. The effects of pain relief were assessed by visual analogue scale (VAS), mechanical pain threshold (MPT), surface electromyography (SEMG). Results In VAS, group comparison had no significant difference after all treatments had done. The difference in VAS between the time before the treatment was started (Day 2) and after all treatments were completed was greater in Acupuncture group than that of needle-electrode group. In MPT, there was no significant difference among groups. Electrical contraction decreased significantly at 2nd before-after treatment comparison in needle-electrode MENS group. But fatigue scores were not significantly different between groups. Conclusions The results suggest that the types of electrodes has no significant effect on microcurrent therapy in DOMS.

Background Despite evidence supporting the safety of breast implants, some women associate their implants with adverse health effects and have called this syndrome "breast implant illness." We sought to characterize breast implant illness symptoms and to report how implant removal affects their symptoms. Methods An anonymous 20 question survey was administered to the Facebook group: "UTAH Breast Implant Illness" to characterize the symptoms these women attributed to their breast implants. Several questions allowed us to evaluate how implant removal affected women's symptoms. Results Of the 182 respondents, 97% report that implants negatively affect their health and 95% identify these symptoms with breast implant illness. Ninety-six percent of respondents had implants placed for cosmetic reasons and 51% had silicone implants. The most common symptoms associated with breast implant illness are brain fog (95%), fatigue (92%), joint pain (80%), and hair loss (74%). Sixty percent of respondents learned about breast implant illness from family/friends and/or social media platforms (56%), 40% of respondents had their implants removed, and 97% report relief of their symptoms post-removal (23% complete, 74% partial). Following explantation, there was a significant improvement in all but one reported symptom. An association was found between the number of symptoms reported prior to explantation and the number of symptoms resolving following explantation. Conclusions Breast implant illness is a syndrome characterized by fatigue, decreased focus, hair loss, and joint pain after the placement of breast implants. Nearly all patients report improvement of symptoms after implant removal. Significant efforts should be made to better understand breast implant illness and its etiology.
