This paper presented the real-time self-tuning learning control based on evolutionary computation, which proves its superiority in finding of the optimal solution at the off-line learning method. The individuals of the populations are reduced in order to learn the evolutionary strategy in real-time, and new method that guarantee the convergence of evolutionary mutations is proposed. It is possible to control the control object slightly varied as time changes. As the state value of the control object is generated, evolutionary strategy is applied each sampling time because the learning process of an estimation, selection, mutation is done in real-time. These algorithms can be applied; the people who do not have knowledge about the technical tuning of dynamic systems could design the controller or problems in which the characteristics of the system dynamics are slightly varied as time changes.

This research examined the relationships of individual and intergenerational variables with psychological well-being(PWB) of elderly females and the relative significance of the effect of these variables on PWB. Structured interview technique was used to collect data from 202 elderly females in Seoul who were recruited through quota sampling method. Two-way analysis of variance result indicated that interaction effect between aged and the presence of spouse on PWB was existed. Though most variables were significantly correlated with PWB of elderly females results of multiple regression analyses indicated that three variables-self-efficacy self-esteem affectional solidarity with adult children- significantly influenced PWB and three variabels-coresiding with the first son's family satisfaction with pocket money and contact solidarity-approached the significance level to the effect on PWB.

A new method for the artificial beta cell which can be used to control the hyperglycemia in diabetic patients was represented. The relationship between the insulin infusion rate and the blood glucose concentration was described by the second order ARMA model, and the time varying parameters were identified by exponentially weighted least squares estimator. The design of controller was based on the pole assignment self tuning altorithm with discrete blood sampling and the constraints of input and output responsse rate were considered. The results of animal experiments show that this method may be a fruitful approach for regulating the blood glucose level. We expect that this device can be used as both therapeutic and research tools providing that its stability and reliability are improved a little more.

This study was designed to explore the effectiveness of education to improve self-care of stroke patients with three types of charactor health locus of control and constitution. A total of 56 patients were selected by convenience sampling at one oriental hospital. The teaching of self-care was conducted by the researcher. The self-care performance was measured for 10 days. The data were analyzed using t-test, ANOVA and Scheffe method as post hoc test. The results of this study are as follows : 1. The self-care performance by patients' characteristics : Age and education had impact on the self-care performance. The level of self-care performance of young and high educated patients was high, gender, religion, occupation, monthly income, and the paralyzed side, however, didn't have influence on the self-care performance. 2. The self-care performance of patients with three types of constitution : There was no statistical significance on the self-care performance of patients group by constitution. However, average score of self-care performance of patients with So-Um was high. 3. The self-care performance of patients with three types of health locus of control : There was no statistical significance on self-care performance of patient group by health locus of control. 4. The correlation between the constitution and the health locus of control : There was no statistical significance on the introverted and chance health locus of control of patients with three types of constitution. However, there was a statistically significant relationship between the powerful others health locus of control and So-Yang. Even though there was no statistically significant self-care performance of patients with So-Um, there was a clinical significance on the high score of self-care performance of patients with So-Um as compared with the self-care performance of the patients. The health locus of control didn't have influence on the self-care performance of patients. There was a statistically significant relationship between the powerful others health locus of control and So-Yang. Therefore, this study suggest the need to develop the nursing intervention to improve the self-care of stroke patients with the powerful others health locus of control and So-Yang, Furthermore, the longitudinal research is needed to determine the effectiveness of training to imp

Self-management training is one of the ways to empower patients to cope with disease. The aim of this before-and-after quasi-experimental study was to determine effects of a teach-back self-management training method on breast cancer patient happiness. Fifty breast cancer patients who visited the Park-e Neshat Limited Surgery Clinic in Kerman, Iran were randomly divided into intervention and control groups after convenience sampling and checking for inclusion eligibility. Data were collected using a demographic questionnaire and the Oxford Happiness Inventory before and after teach-back training and analyzed using SPSS 23. Findings showed no significant difference between mean happiness scores in the two groups before the intervention. However, after the intervention, the mean happiness score in the intervention group increased from 37.2 to 62.9, while it decreased from 41.4 to 29.8 in the control group. These changes were statistically significant (p<0.001). Even after controlling for the effect of confounding factors such as residence location and history of cancer education, the observed differences between the groups were statistically significant (p<0.001). A teach-back self-management training program can increase happiness levels in breast cancer patients. Therefore, the use of this method is recommended to improve self-management and increase happiness.

The purpose of this study was to verify the relationship between students' exercise ability beliefs, academic engagement and self-handicap in physical education class. To this end, this study selected a total of 437 copies of questionnaires as final valid samples using the convenience sampling method targeting middle school students at 4 schools in metropolitan area. For data processing, this study confirmed the goodness of fit test of the whole model using SPSS 20.0 and AMOS 20.0, and then did hypothesis testing; the study results are as follows: First, the increased belief of exercise ability beliefs was shown to have a static effect on the academic engagement, and a fixed belief did not have a significant effect on the academic engagement. Second, the increased belief was shown to have no significant effect on self-handicap, while the fixed belief had a static and significant effect on self-handicap. Third, the students' academic engagement has been confirmed to have a negative effect on self-handicap.

Objectives : Cotinine, the major metabolite of nicotine, is a useful marker of exposure to tobacco smoke and self-reporting of smoking status is thought not to be reliable. This study aimed to evaluate the agreement between the smoking self-report among adolescents and the urinary cotinine test. Methods : The study subjects were 1226 middle and high school students in Hanam city, who were selected by stratified random sampling. The self-report about smoking behavior was compared with urine cotinine value measured with PBM $AccuSign^{\circledR}fi$ Nicotine(Princeton BioMeditech Corporation, USA). The percentage agreement, kappa and 95% confidence interval(CI) were calculated. Results : The overall percentage agreement was 88.6%, and those for boys, girls, middle school, general school and vocational school students were 87.3%, 90.1%, 93.7%, 85,5%, 90.7%, and 78.4%, respectively. The overall kappa index was 0.46(95% CI=0.39-0.54)for overall, .and those for boys, girls, middle school, general school and vocational school students were 0.56(95% CI=0.48-0.65), 0.20(95% CI=0.07-0.32), 0.21(95% CI=0.09-0.34), 0.55(95% CI=0.47-0.64), 0.42(95% CI=0.33-0.52), and 0.48(95% CI=0.36-0.60), respectively. Conclusion : The percentage agreement was relatively high but the kappa values very low for girls, and middle school students. Though the prevalence bias can be influenced by these results, the self-report was not a sufficient tool for the evaluation of adolescents' smoking status, especially in girls or middle school students.

This study was carried out to explore the illness-related activities of the menopaused women. To achieve such a purpose, sixty-six cases of the middle aged women were sampled the naturally and the artificially menopaused group respectively from 1st, Aug. to 31th, Aug. in 1988. For the collection of data, 1, 140 women aged between 45-54 were selected through stratified sampling techniques in urban and rural area. Among them the final subjects for analysis were restricted to only those who had experienced menopause naturally or artificially. And then, after control for age and education analysis was performed. The data was analysed by use of frequency, percentage, $X^2-test,$ t-test, Pearson correlation coefficiency and stop-wise multiple regression. The obtained results were as follows. I. As for the se1f-perception on menopausal symptoms, it was revealed than Korean women, neithe in naturally and artificially, accepted the change of menstruation itself as serious. This shows us that middle-aged women had positively receptive attitudes that the change of menstruation is follwed by amenorrhea. 2. The artificially menopaused group scored more than the naturally one: (I) on the self-control activities such as self-assessment, lay-consultation, fever check, pulse check and observation of vagina discharge, (2) on the self-decision activities such as hospital and pharmacy utilization, (3) on the self maintenance activities such as walking, aerobic, weight check, skin care, skin protect, calori control diet control, milk intake, vegetable intake, cold water drinking before meal, parasol use and BP check The above results lead us that the self care practices of the menopaused women revealed' coping wit I menopausal symptoms at the first level in community and must be developed by the adequate nursin intervention.

PURPOSE: The purpose of this study is to provide the basic data for developing the self-leadership program by identifying the effect of self-leadership on intrinsic motivation among physical therapy students. METHODS: One hundred physical therapy students in E university of Gyeonggido were recruited by convenience sampling from October 4 to 14, 2016. Of them, 89% were chosen and 79% were analyzed after excluding the cases with wrong answers. The survey, using Likert's five scales was conducted with fifteen items of intrinsic motivation (Cronbach's ${\alpha}$, .84) and thirty-five items of self-leadership (Cronbach's ${\alpha}$, .90). Frequency analysis, correlation analysis regression diagnostics, and multiple regression analysis were done with SPSS 20.0 Statistics program (IBM, Korea). RESULTS: The total score of Self-leadership was 3.61 and of substrategies was 4.05 (Natural reward strategy), 3.38 (Behavior-focus strategy), and 3.43 (Constructive thought pattern strategy), respectively. The score of intrinsic motivation was 3.43. The substrategy of Self-leadership indicated positive correlation with intrinsic motivation. The correlation values in higher order were .75 (Natural reward strategy), .66 (Behavior-focus strategy), and .61 (Constructive thought pattern strategy). The Constructive thought pattern strategy (t=5.18, p=.00) and Natural reward strategy (t=2.10, p=.38), except Behavior-focus strategy were effective on intrinsic motivation, according to the multiple regression analysis. CONCLUSION: Before stepping up to the next level of being a physical therapist, students must go through the educational program to improve the Constructive thought pattern strategy and Natural reward strategy.
