In this paper, a study on the physical properties of mortar applying 3D Textile was conducted to compensate for the shortcomings of the existing concrete surface repair and reinforcement method. In the tests conducted to analyze the physical properties, compressive strength, flexural strength, and dynamic modulus measurement tests were conducted. As a result of the compressive strength test, as the number of surfaces to which the stereoscopic fiber was applied increased, the amount of displacement and strength reduction rate increased, and the flexural strength also increased as the number of surfaces to which the stereoscopic fiber was applied increased. In addition, it was confirmed that the use of stereoscopic fibers tended to decrease the dynamic modulus of elasticity. This result is a characteristic of the application of stereoscopic fibers, and it caused a decrease in compressive strength due to a decrease in the mortar content of the part to which the stereoscopic fib er was applied, and the high tensile force of the stereoscopic fiber is believed to have affected the increase in flexural strength.
The purpose of this study was to examine associations between subjective symptoms of musculoskeletal diseases and the degree of job stress among shipyard workers. The study population was 7,078 employees of the D shipbuilding company. Survey data was obtained from 1,727 employees using a proportional sample according to age and a self-administered questionnaire. The associations were examined with ${\chi}^2$ and logistic regression. The main results were as follows: First, the prevalence of musculoskeletal disease in any one part is 59.5% by NIOSH standard. Second, subjects who had worked in the shipyard for over five years had a prevalence of musculoskeletal disease 1.8 times higher than subjects who had worked in the shipyard for less than five years (p<.01). Finally, those who had less support from co-worker's had a prevalence of musculoskeletal disease 1.3 times higher than subjects who had more support from co-worker's (p<.05). Throughout the results, shipyard workers had higher occurrences of musculoskeletal diseases than other manufacturing workers and the risk of musculoskeletal disorder tended to increase with higher job stress. In this research, the plan to reduce musculoskeletal diseases involved making a program and policy which would be able to lower job stress socio-psychologically. This research will prove useful by using basic preventive materials to improve the musculoskeletal health of labores who work in shipyards and similar places.

To design a beautiful hood fitting an unspecific individual, focusing on body parts such as the head, neck and shoulder requires body size and type information, which applied by physical factors like size, types, and movements, etc. These parts consist of complicated types and structures. Accurate information should be a priority due to great individual differences and low correlation with other body parts. However, there is not a lot of detailed physical information nor design methods for hood design. Therefore, the purpose of this study is to select a study sample "hood" which is a recently emerging fashion item and to expand the necessary physical information for pattern design and draw body size of wearing part on Hood like head, cerbical portion and shoulder. Extract factors to consist on types and after divided into several types, a study comparing each type's physical characteristics was conducted. In order to do that, body measurement data have been collected by statistical treatment and analyzed reference with statistical treatment. The results of the study are predicted to be important data to develop various hood designs for the recent fashion trend. Factor analysis was conducted through main composition analysis about direct measured item on human body and index items. The results of factor analysis, composed factors of body type in this research object were extracted in total of 3 factors. To categorize the head, neck and shoulders of women in their early 20s women and determine their characteristics, variances with factor analysis became operative for Cluster analysis. With these clusters, women in their early 20s were categorized into three types. The results of this study are considered to affect largely for higher physical suitability on unspecified individuals when allowed absence of reference and the fact that body size only limited to item 'head circumstance' in terms of making hat and hood in the case of recent Korea. For the future, an experimental study of hood production should be conducted by using basic data from this study.

The purpose of this study was to explore whether there is a point within the range of physical impairment after which the cost of home care exceeds the cost of nursing home care among the elderly who require long-term care. The provision of long-term care for the elderly is a major health policy issue, in part due to the aging of the American population and dramatic increase in health care costs. The framework for this study was guided by Pollak's(1973)model of costs of alternative care settings for the elderly. This study used a retrospective, descriptive correlational design. Physical impairment was measured by the modified Index of Activities of Daily Living(Katz et al. 1963). Cost of care was measured by the average cost per patient per day. The sample for this study included 67 patients receiving long-term care at home from the Long-term Home Health Care Programs (LTHHCPs) and 67 patients receiving long-term care in nursing homes. Data were collected on patient characteristics. including activities of daily living and cognitive impairment. and on the number of physician visits. emergency room visits. and hospitalization from the patient records. For each patient. Medicaid cost data for home care services/or nursing home services were collected from the financial department of each home care agency or nursing home. The living costs and informal care costs were estimated for home care patients. The results indicated that the home care sample and the nursing home sample were similar in terms of gender. ethnic background. and marital status. The elderly patients in the home care sample were: however. younger and less physically impaired than those in the nursing home sample. The hypotheses of this study were supported: For elderly persons with physical impairment scores below 12(possible range of 0 to 14), cost of care was lower in home care than in the nursing home care setting. However, for elderly persons with physical impairment scores above 12. the cost of care was higher in home care than in the nursing home care setting. Thus. in this sample for elderly patients with extreme physical impairment, the cost of home care exceeded the cost of nursing home care.
The purpose of this study was, accordingly, to examine male college student's general body consciousness and their actual condition of wearing clothing, as it's assumed that clothing, which everyone must always wear, might be effective in making up for the physical defect. The findings of this study were as follows : 1. Male College Students'Body Consciousness : They expressed some dissatisfaction with their own body, and they were most discontented with their height, among their bodies. They thought of the western-style shape as an ideal one, as what's considered by them to be ideal was thinner a little than them, being taller with wider shoulder, longer legs, smaller and white face. 2. Male College Students'Characteristics of Clothing Purchasing Behavior : In purchasing clothing, male college students were slightly sensitive about the physical part with which they wasn't satisfied. The clothing pattern preferred by them was an abstract one, and their favorite color was white or black. The greatest number of them put most emphasis on design in buying clothing, and they purchased clothing mainly at special fashion shop. On the whole, they showed an affirmative response toward wearing Korean costume, and they also had a positive opinion about the purchase of reformed Korean dress for everyday life. 3. Male College Students'Characteristics of Wearing Clothing : They appeared not to consider making up for physical weakness. Male college students favored aloha shirt and trousers when they went out. Male college students purchase clothing in consideration of individual, manly, classical, tender, or comfortable factors. 4. Relationship of Body Consciousness to Wearing Behavior : The degree to which they considered covering up physical weakness in wearing clothing was examined, by dividing them into two groups : one was a group that thought their own shape normal, and the other was a group that didn't think of their own shape as normal. As a result, both groups appeared not to consider covering up physical weakness.

PURPOSE: This study was implemented to measure the muscle activity of muscles surrounding shoulder during push-up exercise according to the slope angle. METHODS: This study has research subject consisting of 25 normal male adults without neurologic or musculoskeletal injury in shoulder part. EMG was used as a tool for measuring muscle activity and four muscles including upper trapezius (UT), middle trapezius (MT), Lower Trapezius (LT), and Serratus Anterior (SA) were chosen for measuring the muscle activity of muscles surrounding shoulder. Tilting table slope was set at $0^{\circ}$, $30^{\circ}$, $45^{\circ}$, and $60^{\circ}$ and push-up motion was performed three time for each case to use the average value. The measured value was used after generalization process to create %RVC value where the measured value was standardized by using $0^{\circ}$ as a standard. RESULTS: There was a difference of muscle activity according to the tilting table slope during push-up exercise. In UT, MT, and SA, there was no significant $0^{\circ}$ and $30^{\circ}$, $45^{\circ}$ and $60^{\circ}$. But there was significant $30^{\circ}$ and $45^{\circ}$. LT was significant difference between $45^{\circ}$ and $60^{\circ}$ (p<.05). CONCLUSION: There are cases where push-up exercise should be selectively implemented due to shoulder problems. According to this results between $0^{\circ}$ and $30^{\circ}$, push up will be able to more effectively exercise. Applying proper angle of tilting table for push-up to patients who have difficulties in performing motions along with physical consumption can deliver effective and easy exercise program.

PURPOSE: This study's aim was to investigate the effects of an action observational training in subactue stroke patients with moderate impairment. METHODS: 22 participants (men=13, women=9) with hemiparesis were randomly assigned to action observation training group or task-oriented training group. Patients in both group underwent a patient-specific multidisciplinary rehabilitation program. Participants in the action observation group (mean age, $62.78{\pm}9.85$) were asked to watch the video scene, in the knowledge that they would then attempt to perform the same movement task after watching. The control group (mean age, $61.49{\pm}8.64$) practiced the same tasks, without watching the video. To evaluate upper limb function, the upper extremity part of the Fugl-Meyer Assessment upper extremity and the Box and Block Test were used. The modified Barthel index was used to assess ADLs, and the modified Ashworth scale were used to assess spasticity in the upper extremity. RESULTS: The action observational training group exhibited greater changes in the Fugl-Meyer assessment upper extremity (P<0.05; 95% CI, 0.929 - 6.403), the Box and Block test (P<0.05; 95% CI, 0.086 - 5.913), and the modified Barthel index (P<0.01; 95% CI, 2.483 - 12.627) between groups. And the modified Ashworth scale (P>0.05; 95% CI, -0.402 to 0.624) did not show significantly different between groups. CONCLUSION: These findings suggest that action observational training may be more helpful to improve upper-extremity function than physical training only in subactue patients with moderate impairment after stroke.

The aim of this study was to determine the basis for smooth conduction of business for journalists by identifying the journalists demographic characteristics and the relevance of the physical symptoms and emotional exhaustion. The surveys were carried out from 2013 May 1 to August 31 and the subjects of the surveys were 124 journalists working in the editorial part of 11daily newspaper companies located in Seoul. For data analysis, frequency analysis, factor analysis, and a T-test were performed using the SPSS Win 18.0 program. A p value 0.05 was considered significant. The study showed that there were significant differences in the physical symptoms depending on sex, age, marital status, and rank. In addition, emotional exhaustion was affected by gender, age and Sunday duty cycle etc. The results of this study will provide basic data for preparing a physical and mental health promotion program for journalists by the demographic characteristics.
The purpose of the study is to search for the possibility of the application of kinematics analysis to physical education at schools and expand its scope of application. This study chose 9 college students majoring in physical education and classified them into type A group who can make the straight, vertical handstand, type B group whose waist is bent, type C group who cannot handstand completely. The center of mass, distance between hand and leg, and the angle and angular velocity of each joint were obtained. The result of this study is this. 1. The time for CM showed 6:4 for A group and 5:5 for B and C groups. The distance between hand and foot in the event 3 was 44% of the height for A group, and 41% for B and C groups. A Group showed the higher CM positional significant difference, it was vertically direction below the hip joint at front. For significant difference of the B Group showed horizontal and vertical velocity of the CM, the highest vertical was obtained in phase 3. The difference of angle of shoulder join in the flexion/extension was showed gradually extension event 2 and the height angular velocity was at phase 3 in the A group. 2 The analysis of the handstand motion revealed that the phase 3, but the maintenance of posture start part the handstand is also very important. Through these results, this study confirmed that the time for phase of the CM, horizontal and vertical positions, velocity, the distance between hands and foot, and the difference of the angle and angular velocity of hip joint and shoulder joint can be set as the variables of analysis. It was also definite cause that the handstand motions of college students majoring in physical education had many difference in performance.

Low back pain is generally defined as a complex symptom rather than a specific diseases entity, especially when musculoskeletal lesions of the low back, neurogenic, vasculogenic and discogenic lesions are present. Sixty to eighty percent of all human being have experienced low back pain once or more times during in their lifetime. Low back pain is a one of the commonest cause of physical impairment and induces disability the activities of everyday living or the activities of work. Today, low back pain plays important part for the loss of working capability from social, industrial field and individual daily life. But there are no study about incidence and prevention program of low back pain in rural peoples. This study was conducted to find out current status and characteristics related to low back pain in rural peoples(especially engaged in agriculture), so that could provide basic data to establish prevention program for them. The data were gathered from 301 rural adults(female 62.1%, male 37.9%) with low back pain by the structured interview in the 4 communities(south and north Gyeong-sang Do and Chung-cheong Do), and sampled at local hospital, local clinic, and health clinic center in May, 2000. The results were as followed. About one third of cases(35.5%) were aged from 60 to 69, 34.6% were smoker, and 91.4% not used to regular exercise. Low back pain frequently due to intervertebral articulopathy(42.5%), follewed by herniated intervertebral disk(19.9%), sprain(17.3%), vertebral dislocation(4.0%), and etc(16.2%). Above half of cases(56.5%) were a eight-hour workday, and 61.8% complained of low back pain during work. Mostly, period of agricultural experience was more than 20 years, and cultivated more than 2 crops. Low back pain is common to rural adults, therefore adequate resting time from work and lumbar strengthening exercise program needed to prevent low back pain in rural peoples.
