This study was done to Identify the relations between psychosocial factors and symptoms of patient with rheumatoid arthritis. Its subjects were 150 outpatients selected at H. Rheumatism clinic from July to August in 1998. Data were collected by means of questionnaires using interview. Those data were analyzed by Frequency, t-test, ANOVA, pearson's correlation using SPSS window 8.0. The results were as follows : 1) The level of family support was relatively high and the level of self-efficacy and performance of daily living activities were average. Among their symptoms, fatigue and pain were frequent problems. 2) Family support was different by educational level, self-efficacy and physical, psychological symptoms were different by performance of regular exercise. 3) The family support was inversely related to physical symptoms especially ADL, while it was not related to psychological symptoms except a reverse correlation between depression and anxiety, and family support. Self-efficacy held a reverse correlation with both physical and psychological symptoms. And there was a close relationship between symptoms. In conclusion it was found that the promotion of family support, self-efficacy and exercise-performance holds a key post in reducing symptoms of rheumatoid arthritis.

Purpose: This study was aimed to identify the factors that influence eating behaviors in coronary artery disease patients and to create data for nursing which is thought to improve the eating behavior. Method: The study population was coronary artery disease patients who were treated on an outpatient basis. The measurements were eating behavior, diet self-efficacy, perceived-benefits, perceived-seriousness, family support and medical team support. All of the measurement tools above were thoroughly modified to verify validity and reliability. Statistical analysis was done by the SPSS PC 12.0 program. Results: The influencing factors for the eating behavior was diet self-efficacy (${\beta}=0.476$), social support (${\beta}=0.253$), chest pain (${\beta}=0.177$), smoking (${\beta}=-0.173$) and regular exercise (${\beta}=.169$), which explained 46.2%. Conclusion: Eating behaviors of coronary artery disease patients were influenced by diet self-efficacy, family support and the presence of chest pain. Therefore, the development of a program for efficient dietary education that prevents the progression of coronary artery disease is needed.

Background: Qigong is one of energy-healing intervention used to prevent and cure ailments and to improve health through regular practice. Although Qigong-neither itself nor its postulated mechanism of action-is within the paradigm of modern Western medical science, effects on the human body could be possible. Objectives: This study aims to know effect of Qigong training in a University student's physical, mental health and self-esteem. Method: There are 120 students who take a Yangsaengkigong(養生氣功) course in D University college of oriental medicine during four weeks beginning in April 10th 2008. I researched 41 of them trained about effect of Qigong training. Result: Qigong training made significant change in self-esteem measurement and SCL-90-R. And there wasn't significant change in KHP and happiness index. Conclusions: The depth study for the each Qigong is needed. Specifically, I think it should be a clinical studies and qualitative research methods for evaluation are needed.

Objectives: The purpose of this study was to investigate estheticians' self-reported pain symptoms and pain levels according to the parts of the hand. Methods: Data were collected through a questionnaire survey among 116 estheticians from 31 skin care centers and spas. Information about general characteristics, job characteristics and work characteristics were based on data from the self-administered questionnaire. To determine the self-reported pain symptoms and pain levels according to the parts of the hand, a Cornell Musculoskeletal Discomfort Questionnaire was used. Results: The subjects had the greatest self-reported pain symptoms in the thumb(Right: 53.4%, Left: 46.6%) and felt the highest level of pain in the wrist(Right: 4.87 points, Left: 4.71 points). Physical burdens and age had statistically significant effects on the pain level in the right hand, while physical burdens and the manager rather than the director had statistically significant effects on the pain level in the left hand. Conclusions: Since the thumb and wrist have the greatest subjective pain symptoms in the hand, the use of proper tools is recommended in order to reduce the usage of the thumbs during massage, as is regular stretching to protect the wrists.

When a recess is applied to a swirl coaxial injector that uses liquid and gas propellants, a self-pulsation phenomenon in which the spray oscillates at regular intervals may occur. The phenomenon is caused by the interaction between the liquid and gas propellants inside the injector recess region. The propellants' kinetic energies are expected to affect significantly the spray oscillation. Therefore, cold-flow tests using helium as a gas-simulating propellant were conducted and compared with the results of the previous study using air. Dynamic pressure was measured in the injector manifold and frequency characteristics were investigated through the fast Fourier transform analysis. In the experimental environment, the helium density was about seven times lower than the air density. Accordingly, the intensity of pressure fluctuations was confirmed to be greater when air was used. At the same kinetic energy condition, the perturbation frequency was almost identical in the low flow rate conditions. However, as the flow rate increased, the self-pulsation frequency was higher when helium was used.

Purpose: This study described female college students' knowledge, self-efficacy and health behaviors related to bone health. Methods: A descriptive cross-sectional survey design was used. A total of 214 students were conveniently recruited from a school of nursing in Korea. Participants (mean age=21.2, SD=1.9 years) bone mineral density (BMD) was measured using dual energy x-ray absorptionmetry. Participants also completed a questionnaire consisting of knowledge test, self-efficacy scale and health behaviors related to bone health. Data were analyzed using SPSS/WIN 17.0 program. Results: The mean BMD at left femoral neck site was $0.86g/cm^2$ and 6.1~12.6%. Results showed that participants were below the expected range of BMD. Level of knowledge (correct rate=54%) and self-efficacy were moderate (mean 54.8 out of 84). More than 84% of subjects drank alcohol more than once a month and 58.4% did participate in regular exercise. Only 7.9% participants took calcium and vitamin-D rich foods every day. There were significant positive correlations between knowledge and self-efficacy (r=.17), health behaviors (r=.14) and self-efficacy and health behaviors (r=.28, all p<.05). Conclusion: These results suggest that health care professionals need to provide effective interventions for young women in order to enhance knowledge, self-efficacy and health behaviors related to bone health.

Purpose: This study aimed to analyse female academician health beliefs for breast cancer screening and levels of self-esteem. Materials and Methods: This cross-sectional study was conducted between October 2010 and March 2011, covering female academicians working in all faculties and vocational schools at Ondokuz Mayis University, except for the ones in the field of health (n=141). Data was collected using a questionnaire developed by researchers in the light of the related literature, the Champion's Health Belief Model Scale for Breast Cancer, and the Coopersmith Self-Esteem Inventory. Descriptive statistics, the t-test, Mann-Whitney U and correlation analysis were used to analyze the data with the SPSS 13.0 statistical package. Results: 53.8% of the participants were single, 58.6% did not have children, 80.7% had regular menstrual cycles, 28.3% was taking birth control pills, 17.9% were undergoing hormone therapy, 11% suffered breast problems, 8.3% had relatives with breast cancer, 78,6% knew about breast self-examination (BSE), 68.3% was performing BSE, 16.2% were performing BSE monthly, 17.9% had had mammograms, and 30.3% had undergone breast examinations conductedby physicians. The women who had breast physical examinations done by physicians had higher susceptibility, self-efficacy and health motivation, and fewer barriers to mammography than those who did not have breast physical examinations. Conclusions: There was a relationship between the female academician self-esteem and their perceived seriousness of breast cancer, perceived barriers to BSE and health motivation. Our Turksih female academicians had medium levels of self-esteem.

This study was conducted to investigate and to compare the health status of urban and rural elderly in Korea using the following factors: 1) the number of self-reported health problems 2) a self-rating score for health status 3) the number of diagnosed diseases 4) ADL, social health status by IADL and the psychological health status by Life Satisfaction scale developed by Wood and others. The study subjects were the elderly who lived in Pusan(N=150) as an urban area and Kyeungnam(N=300) province as a rural area. The study subjects were sampled at random and the data were collected by trained interviewers from Feb. 1 to Feb. 14, 1995. the data was analyzed in SPSS. The results can be summarized as follows : 1. According to the sociodemographic characteristics of the subjects, the urban elderly group was significantly higher in extended family groups and in practicing regular execise than the rural elderly: and the rural elderly group was higher in having spouses and occupations than the urban group. 2. Concerning health status, the numbers of self-reported health problems(eye problems, back pains, headaches, dental problems, arthritis) and number of diagnosed diseases(hypertension, heart problems, diabetes mellitus, neuralgia, arthritis) were significantly were higher higher in rural areas: the self - rating scores for health status and life satisfaction were higher urban areas. ADL and IADL were similar in both the rural and urban elderly. 3. The correlations were the following: Self-reported health problems and self-rating for health status were significantly correlated negatively(r=-.039, p=.000), but self-reported health problems and the number of diagnosed diseases were significantly positively correlated(r=0. 30, p=.000). IADL and health problems were negatively correlated(r=-0.16, p=.000), but IADL and ADL were significantly positively correlated (r=0.49, p=.000). Life satisfaction and self-rating scores for health status were significantly positively correlated(r=0.26, p=.000).

We construct a symmetric finite volume element (SFVE) scheme for a self-adjoint elliptic problem on tetrahedron grids and prove that our new scheme has optimal convergent order for the solution and has superconvergent order for the flux when grids are quasi-uniform and regular. The symmetry of our scheme is helpful to solve efficiently the corresponding discrete system. Numerical experiments are carried out to confirm the theoretical results.

In 1994, Lim-Xu asked whether the Maluta's constant D(X) < 1 implies the fixed point property for asymptotically nonexpansive mappings and gave a partial solution for this question under an additional assumption for T, i.e., weakly asymptotic regularity of T. In this paper, we shall prove that the result due to Lim-Xu is also satisfied for more general non-Lipschitzian mappings in reflexive Banach spaces with weak uniform normal structure. Some applications of this result are also added.
