Introduction : Exercise has been suggested as an important nursing strategy in which to help elderly maintain functional performance and to enhanced quality of life. Most of exercise study has been reported on fitness exercise such as walking, swimming, dance etc for health of elderly. There have been few reports about exercise on the promotion of small and fine movement of elderly. The purpose of this pilot study was to determine an effect of 6 weeks hand and finger exercise in home to improve hand muscle strength such as grip strength and finger pinch pressure. Materials and Methods Design: This pilot study was used one group pre and post-test design. Sample: Twelve elderly women above 60 years of age or older living in community were selected by convenient sampling. Procedure: Signed informed consent was obtained prior to participate in this study. The authors met elderly and taught hand and finger exercise, daily a week for 6 weeks, within 30 minutes per session. But exercise frequency and strength were not same. Instruments: Left and right grip strength were measured by Bulb Dynamometer(made in USA) and left and right pinch pressure were measured by Baseline Hydraulic Pinch Gauge(made in USA). Data analysis: Discriptive data analyses were performed on all variables. Wilcoxon matched-pairs Signed-Ranks test were used to find difference of grip strength and pinch pressure between pre and post exercise using SPSS 10.0 for Window. Results: Samples age ranged from 60 to 73, Mean age was 65.3. All were women. Ten elderly were diagnosed osteoarthritis and one had DM. After six weeks hand and finger exercise, Left and right grip strength were higher than those of before exercise(Z=-2.667, P<0.01 ; Z=-3.065, p<0.01). And left pinch pressure after hand and linger exercise were higher than that of before pinch pressure (Z=-2.315, p<0.05). But Right pinch pressure was not shown significant change(Z=-1.099, p>0.05). Conclusions: Although this study was limited by the sample size and design, the findings provide some important implications for community based exercise nursing intervention. Short term (six weeks) exercise of hand and linger is shown to be useful as nursing intervention to maintain routine daily activities such as eating, writing, grip something for elderly.

Recently, steel-concrete composite slab decks have been widely used as highway bridge decks. In the construction of the composite slab decks, it is necessary to join two adjacent blocked bottom plates to form one unite in the longitudinal direction. In this paper, several types of longitudinal direction joints for Robinson type composite slab decks ared proposed herein and static bending test are carried out by using slab specimens. And the stress and deformation of the tensile grip connection with high strength bolts are discussed by using three-dimensional elastic-plastic FEM.

Purpose : This study's purpose is consideration about change of the hand grip strength according to different posture and shoulder flexion angle. The shoulder joint permits the greatest mobility and carries out the important function of stabilization for hand use. Hand grip activity is important to evaluate while assessing loads of shoulder in hand mobilities. Methods : Thirty(15 male, 15 female) college students with unknown shoulder dysfunction participated subject in five different positions of elbow extension with sitting and standing posture, different positions is followed : (1) shoulder $0^{\circ}$ flexion (2) shoulder $45^{\circ}$ flexion (3) shoulder $90^{\circ}$ flexion (4) shoulder $135^{\circ}$ flexion (5) shoulder $180^{\circ}$ flexion. Results : On the average, in the hand grip strength, the standing posture is higher than sitting posture. Sitting posture showed a most high level at the man's $0^{\circ}$ and woman's $135^{\circ}$. And standing posture showed a most high level at the man's $135^{\circ}$ and woman's $90^{\circ}$. Conclusion : The paired t-test was used to determine the different in grip strength between sitting and standing posture by shoulder angle change. There was no significant difference between the five position by sitting and standing posture. In man, correlation analysis revealed significant connection for all five position by sitting and standing posture. And in woman, correlation analysis revealed connection for all five position by sitting and standing posture.

Wrist PA-grip view is used to diagnose triangular fibrocartilage complex (TFCC) tear because it can easily diagnose damage to the surrounding wrist ligaments. However, despite advances in radiology equipment, distortion of images due to geometric elements still has many limitations. In this paper, we propose a method that can minimize the distortions of images by analyzing the distortions occurring in the wrist PA-grip view. A source of image distance (SID) were set at 130 cm and 150 cm for comparison with 110 cm. Depending on the SID, the phantom of wrist was moved at 0, 2, 4, 6, 8, and 10 cm in the X-axis and Y-axis directions, respectively. For quantitative evaluation, the difference of distance between the radius and ulna was measured in picture archiving and communication system (PACS) system. As a qualitative evaluation, survey was conducted among 20 radiologic technologists who examined the Wrist PA-grip view. The Kruskal Wallis test was performed to compare the distortion according to the phantom movement in the X-axis and Y-axis directions based on the SID, and the Tukey test was performed as a post-test. In the quantitative evaluation results, the measured values obtained in the X-axis was not significantly different in all groups (p>0.05). The measured values obtained in the Y-axis was significantly different in the most groups (p<0.05). Therefore, to reduce distortion while maintaining image quality, we recommend what examine the SID at 150 cm than 110 cm.

The aim of study was to investigate the effects of 12 forms of Sun-style Tai-Chi for arthritis(TCA) on physical symptom(pain, tenderness, swelling fatigue, and blood pressure), physical function(balance, flexibility, grip strength) and social-psychological health status in osteoarthritis(OA) patients and rheumatoid arthritis(RA) patients. This study was done with one group pretest-posttest design. A total 21 arthritis patients(6 OA patient and 15 RA patient) participated in 60 minute session consisting of warm-up exercise 12-main movement including qigong, and cool-down exercise twice a week for 6weeks. Physiological and social-psychological variables were measured before and after TCA 12 form. The researcher who completed a Tai Chi workshop for exercise leaders in Australia and Seoul taught the Tai Chi movement step by step until the patient felt comfort enough to perform them correctly by themselves during the first 4 weeks. At the last 2 weeks, the subject perform 10-15set of these at a session with traditional music to help patients move in a slow tempo. TCA 12 forms program showed significant improvement in fatigue(p=0.039) of rheumatoid arthritis patient and pain(p=0.006), fatigue(p=0.013), tenderness(p=0.032), flexibility(rt arm up, p=0.014, If arm up, P=0.003), grip strength(rt hand, p=0.002, If hand, P=0.003) of osteoarthritis patients. With assessment by Arthritis Impact Measurement Scale 2 questionnaire(AIMS2), physical component(0.002) and social interaction(0.025) on osteoarthritis patients were significantly improved. Evaluation of the participants about TCA exercise noted that the exercise was fairly easy(23.6%), moderately difficult(57.1%), and fairly difficult(14.3%). Considering the result of this study, TCA exercise program was more effective in pain, tenderness, grip strength, flexibility, and physical and social interaction on osteoarthritis patients than rheumatoid arthritis patients. Tai-Chi for arthritis 12 form was an appropriate intensity exercise for osteoarthritis patients.

Purpose: This thesis study aimed to examine the effects of elastic-band resistance exercise on physical fitness, activities of daily living (ADLs), falls efficacy, and quality of life among older women receiving home nursing care under long-term care insurance. Methods: We used an equivalent control group pre-test/post-test design. We assigned older women at the nursing care center J to the experimental group (n=21), and older adult women at the nursing care center H to the control group (n=21). The experimental group engaged in an elastic band resistance exercise twice per week from February 18 to April 12, 2019. Results: There were significant differences in the Short Physical Performance Battery score (t=4.15 p<.001), left grip strength (t=0.57, p<.569), right grip strength (t=1.38 p<.177), flexibility test scores (t=2.34, p<.024), ADLs (t=6.86, p<.001), falls efficacy (t=5.16, p<.001), and quality of life (t=3.87, p<.001). Grip strength was increased slightly in the experimental group, but the increase was not significant. Conclusion: Elastic band resistance exercise is an effective nursing intervention to enhance physical fitness, flexibility, ADLs, falls efficacy, and quality of life among older women receiving home nursing care under long term care insurance.

Purpose: The purpose of this study was to analyse the effects of Tai Chi on the muscle strength and flexibility. Method: 10 articles from Medline search of foreign journals(1981-2003) and 4 from Korean nursing journals (1981-2003) were surveyed. The research are analyzed according to research design, subjects, and dependent variables. Results: Research on Tai Chi Exercise increased rapidly in the 1990's. The experimental research design was more reported than the comparative design. The experimental design included; 21.4% one group pre-posttest design, 35.7% quasi-experimental design and 28.6% randomized design. Out of the subjects; 64.4% of papers were healthy older people, and 35.6% of papers were patients with osteoarthritis or rheumatoid arthritis. Style of Tai Chi was mostly used Yang or Sun form. Muscle strength was usually measured at lower extremity or grip strength. Classical Yang style or Long form was more effective to improve muscle strength. 75% of papers were significantly improvement in grip strength and 71.4% of papers in flexibility. Conclusion: To properly study the positive effects of Tai Chi exercise, it is suggested that meta analysis needs to be done to integrate the various results.
