The effects of coping on physical and psychosocial adaptation in the 297 patients with rheumatoid arthritis were investigated. The coping methods were divided into compliance of medical regimens, self-control activities, and cognitive control. The effects of these coping methods was analyzed with stepwise regression. The physical adaptation is found to be significantly affected by cognitive control, self-control activities, and compliance of medical regimens in order Compliance of the medical regimens affects negatively the physical adaptation. And psychosocial adaptation is significantly affected by the cognitive control. The analysis of these results by illness duration showed the distinct differences. That is in the patients who experienced the disease less than 48 months, the physical and the psychosocial adaptation were significantly affected only by the cognitive control. But in the patients who experienced the disease more than 96 months, the physical and the psychosocial adaptation were significantly affected by self-control activities. Based upon these results, it is recommended that the nurses who care the newly diagnosed patients emphasize on the positive side of the state. And the patients who are diagnosed long ago need the nursing programs which teach and promote self-control activities. Also it is suggested that the results of compliance must be considered rather than as the result variable.

Purpose: This study was conducted to explore the mediating effect of resilience in the relationship between stress and therapeutic compliance in patients with systemic lupus erythematosus. Methods: The subject (N=145) was a systemic lupus erythematosus patient who visited the D Hospital in B city. Data collection was conducted from January 2016 to August 2016. Twenty-five resilience measurement tools, 20 stress measurement tools, 39 therapeutic compliance measurement tools used to measure resilience, stress and therapeutic compliance levels. The collected data were analyzed using descriptive analysis, Pearson correlation, 3-step regression analysis of Baron and Kenny, and Sobel test in SPSS/WIN 21.0. Results: There was a significant negative correlation between stress and therapeutic compliance, a significant negative correlation between stress and resilience, and significant positive correlation between resilience and therapeutic compliance. Resilience showed a direct effect on therapeutic compliance through stress as a mediating variable. Conclusion: It is necessary to develop appropriate resilience enhancement program to improve therapeutic compliance with systemic lupus erythematosus.

The inverse kinematics problem of a reclaimer which excavates and transports raw materials in a raw yard is investigated. Because of the geometric feature of the equipment in which scooping buckets are attached around the rotating disk, kinematic redundancy occurs in determining joint variable. Link coordinates are introduced following the Denavit-Hartenbery representation. For a given excavation point the forward kinematics yields 3 equations, however the number of involved joint variables in the equations is four. It is shown that the rotating disk at the end of the boom provides an extra passive degree of freedom. Two approaches are investigated in obtaining inverse kinematics solutions. The first method pre-assigns the height of excavation point which can be determined through path planning. A closed form solution is obtained for the first approach. The second method exploits the orthogonality between the normal vector at the excavation point and the z axis of the end-effector coordinate system. The geometry near the reclaiming point has been approximated as a plane, and the plane equation has been obtained by the least square method considering 8 adjacent points near the point. A closed form solution is not found for the second approach, however a linear approximate solution is provided.

In order to assess the impact of proprioceptive exercises on the position sense ability of the knee joint, we conducted an analysis using Biodex System $3pro^{(R)}$, targeting 42 ordinary people (male=22, female=20). After applying proprioceptive exercise, we measured changes in balance and flexibility, and active articular position sense (AAPS), depending on gender. To find out the change in each measurement item variable, we carried out dependent t-tests. The statistical significance level was set to 0.05. The research showed that after applying the proprioceptive exercise, AAPS was significantly improved for both men and women (p<.01). In the case of women, the flexibility was significantly improved (p<.01). Also, the balance was significantly improved for both men and women (p<.01). Therefore, the proprioceptive exercise program is considered to be very useful in improving muscle and joint function, and preventing injuries. Thus, continuous clinical studies using Biodex system $3pro^{(R)}$ are required for a variety of scientific evaluations of proprioceptive skills.

Purpose: This study examined the influence of visuomotor congruency on learning a relative phase relationship between a single joint movement and an external signal. Methods: Participants (N=5) were required to rhythmically coordinate elbow flexion-extension movements with a continuous sinusoidal wave (0.375 Hz) at a $90^{\circ}$ relative phase relationship. The congruent group was provided online feedback in which the elbow angle decreased (corresponding to elbow flexion) as the angle trajectory was movingup, and vice versa. The incongruent group was provided online feedback in which the elbow angle decreased as the angle trajectory was moving down, and vice versa. There were two practice sessions (day 1 and 2) and each session consisted of 6 trials per block (5 blocks per session). Retention tests were performed 24 hours after session 2, and only the external sinusoidal wave was provided. Repeated ANOVAs were used for statistical analysis. Results: During practice, the congruent group was significantly less variable than the incongruent group. Phase variability in the incongruent group did not significantly change across blocks, while variability decreased significantly in the congruent group. In retention, the congruent group produced the required $90^{\circ}$ relative phase pattern with significantly less phase variability than the incongruent group. Conclusions: Congruent visual feedback facilitates learning. Moreover, the deprivation of online feedback does not affect the congruent group but does affect the incongruent group in retention.

Osteoporosis is a age-related metabolic disorder. Currently there is no cure, but there are measures that can prevent or deter the development of osteoporosis. Futhermore lifestyle among risk factors of osteoporosis may be modifiable. Osteoporotic preventive health promotion behavior may be more effective at early adult when make formation of peak bone mass. The purpose of this study was to identify of relation between the demographic variable, osteoporosis-related lifestyles and the health promotion behavior of University and College Female Students. The results were followed: 1. Demographic variables according to the health promotion behavior were significantly difference with age, body height, religion and income. 2. Osteoporosis-related lifestyles according to the health promotion behavior were significantly difference with element school milk intake, current milk intake, exercise and caffeine intake. 3. Health promotion behavior was positively correlation with age, body weight, height income, element school and current milk intake and exercise.

Purpose: The purpose of this study was to examine the effects of static stretching and Evjenth-Hamberg stretching on isokinetic muscle strength of knee flexors and extensors. Methods: The subjects were composed of eighty healthy males without weight-training experience. ROM of knee joint measured active maximal extension and isokinetic Peak Torque measured $60^{\circ}/sec,\;120^{\circ}/sec$ using an the En-Knee. Three tests(Baseline, 4 weeks, 8 weeks, respectively) was operated to examine change of each variable. Data were analyzed with a $2{\times}3$ analysis of variance ($group{\times}test$) for repeated measures on last factor by SPSS package 10.0. The data analysis revealed muscle strength were dependent on stretching method. Results: The results were as follows. First, Evjenth-Hamberg stretching(E-HS) was more effective than static stretching(SS) on ROM. Second, Peak Torque of knee flexors and extensors was improved in both methods by each time. but E-HS was more improved than SS. Conclusion: In conclusion, This study indicates that E-HS is more efficient than SS on muscle strength improvement.

Purpose: This study aims to investigate the fear of falling of stroke patients and identify factors affecting the fear of falling. Method: For basic data, structured questionnaires were used for 137 stroke patients in hospitals in B city sampled for this study from June to August, 2010. Results: A multiple regression analysis used to identify variables affecting the fear of falling of stroke patients indicates that the most affecting variable was activities of daily living (${\beta}$=-.558), followed by self-efficacy of falling (${\beta}$=-.223), primary caregiver (${\beta}$=-.118), perception of health (${\beta}$=-.128) and drunken status (${\beta}$=-.108). Total variance explained by activities of daily living, self-efficacy of falling, the primary caregiver, perception of health and drunken status was 81.2% (F=70.845, $R^2$=.812). Conclusion: As discussed above, the factors significantly affecting the fear of falling in stroke patients were activities of daily living and self-efficacy of falling. Therefore, in order to reduce fear of falling of stroke patients and prevent falling, it is suggested that programs should be developed that will improve self-efficacy of falling and daily living activities.

The study aims to compare the effects of employing investment deposits (joint and specified investment deposits) in Islamic banks, and investment deposits (term deposits and deposits with notification) at conventional banks, on shareholders' profitability, represented by the earnings per share (EPS), in light of operational profits as a controlling variable. Data related to the study variables was collected from the annual financial reports published by the study sample banks, during the period (2009-2018). The study relies on multiple regression to test the hypotheses of the study. The high adjusted R² to explain the change in EPS for Islamic banks model as compared to conventional banks, is a result of the high difference between investment deposits (specified and joint) at Jordanian Islamic banks and investment deposits (term deposits and deposits with notification) at Jordanian conventional banks. The study found that it is important for the managements of Islamic banks to adopt a uniform method to combine speculative funds, in order to develop and improve shareholders' profitability. The study recommended Islamic banks to follow practical, methodological and transparent approaches to calculate the rates of Murabaha profit margins between shareholders and depositors, while also taking into consideration some of the issues which could be harmful for the competition between Islamic and conventional banks.
