Purpose: This study was performed to identify relationships among stress, hardiness, and the level of self-care in kidney transplant patients and use the results of this study as baseline data for developing self-care promotion programs. Method: Subjects were 41 patients who undergone a kidney transplantation surgery at least one month before and were receiving regular follow-up care via OPD. Four researchers interviewed each subjects by filling out questionnaires. Results: The mean score of the level of stress was 2.32(SD=0.54) on a 4 point scale and the mean score of hardiness was 4.68(SD=0.62) on a 6 point scale. The mean score of self-care among the subjects was 3.83(SD=0.55). There was statistically a significant positive relationship between selfcare and hardiness(r=0.42). Especially, relationships between self-care and commitment (r=.51) and control(r=.36) as the subdimensions of hardiness were significant. The item suggested as most stressful was economic burden and the item suggested as least stressful was sexual activity. Conclusion: Although transplant patients have various stressors, the positive self-care activities of the patients could be increased if the commitment and control were enhanced by proper intervention programs.

This study was done to suggest directions for research and interventions of health promoting behaviors in Korean older adults in the future. Thirty seven articles for health promoting behaviors in Korean older adults were reviewed and analyzed. Findings are summarized as follows: 1) The total scores of the HPLP in Korean older adults were 2.30-2.44 out of 4 points. In the subscale, the highest degree of performance is nutrition, following interpersonal support, self actualization, stress management, health responsibility and the lowest degree of performance was exercise. 2) The total scores of the Health Behavior Assessment Tool of the Korean Elders were 2.87-3.2 out of 4 points. 3) Among the characteristics of older adults, monthly pocket money, previous job had consistently significant relationships with health promoting behaviors. Sex, job and presence of disease were consistently insignificant relationships with health promoting behaviors. 4) Perceived health status, self efficacy, self esteem, family support and social support had consistently significant correlations with health promoting behaviors. 5) In regression analysis, self efficacy, family support, depression, self esteem were the most powerful predictors of health promoting behavior in more than two articles. Predictors accounted for 14.2-65.2 % of the variance in health promoting behaviors of Korean older adults. On the basis of above findings, It is necessary to develop the interventions for more regular practice of the health promoting behaviors in Korean older adults. The interventions are recommended to focus increasing the exercise & health responsibility and to use the strategies to increase self esteem, self efficacy, social support including family support.

The purpose of this study was examine the determinants of highschool students' health behavior. A convenient sample of 2nd grade highschool students (N=638) responded to self-report questionnaires. The IMCHB was then tested with data using SAS program by frequency, t-test, ANOVA, regression. The results were as follows 1. Health behaviors were found to be type of school specific. 2. From the general highschool's model, student's health affected health perception and mother's health and father's education affected self esteem among a set of background variables. Health perception and self-esteem are related to health behaviors. 16.8% of the varience in regular highschool student's health behavior are explained by health perception and self-esteem. 3. From the vocational highschool's model, 20.2% of health behavior varience was explained by self-esteem. Mothers' education, health perception and self esteem explained internal motivation. Student's health, internal motivation and self-esteem explained health perception. The results indicated that there was a relatively poor fit of the IMCHB to the highschool students' data.

This paper employs computational tools to predict power increase (or speed loss) and propulsion performances in waves of KVLCC2. Two-phase unsteady Reynolds averaged Navier-Stokes equations have been solved using finite volume method; and a realizable k-ε model has been applied for the turbulent closure. The free-surface is obtained by solving a VOF equation. Sliding mesh method is applied to simulate the flow around an operating propeller. Towing and self-propulsion computations in calm water are carried out to obtain the towing force, propeller rotating speed, thrust and torque at the self-propulsion point. Towing computations in waves are performed to obtain the added resistance. The regular short head waves of λ/LPP = 0.6 with 4 wave steepness of H/λ = 0.007, 0.017, 0.023 and 0.033 are taken into account. Four methods to predict speed-power relationship in waves are discussed; Taylor expansion, direct powering, load variation, resistance and thrust identity methods. In the load variation method, the revised ITTC-78 method based on the 'thrust identity' is utilized to predict propulsive performances in full scale. The propulsion performances in waves including propeller rotating speed, thrust, torque, thrust deduction and wake fraction, propeller advance coefficient, hull, propeller open water, relative rotative and propulsive efficiencies, and delivered power are investigated.
