Recently, there has been increase perception of health promotion with development of the economic state and science. Individual's responsibility and psychosocial factors have impacted on the individual's lifestyle. Health promotion can be maintained or improved through changes of lifestyle of individuals. Also, there have been supported results of health behavior research. But much of the existing research in women's health has been focused on menopausal symptom and reproductive organ. Until recently, little research has been available on the health or health care of midlife women. The purpose of this study was to explain relationship between health promoting lifestyle and hardiness, gender role characteristics. A total of 254 items of data were obtained from randomly selected subjects. The data collected from the interviews were analyzed using SPSS, yielding frequency, mean, t-test, ANOVA, Pearson Correlation, Stepwise multiple regression. The result of this study are as follows : 1) For the health promoting lifestyle, the mean score was 116.3, the highest score was nutrition (3.30) and interpersonal support (2.86), the lowest score was exercise (1.68). The highest subscale for the hardiness was commitment (2.44). Also for the gender role characteristics was higher than median score (37.8). 2) There was a statistically significant difference the demographic variables. A total health promotion lifestyle was predicted by income and marriage satisfaction, hardiness was predicted by education, income, marriage satisfaction, support person and gender role characteristics was predicted by education. 3) With regard to the relationship among health promoting lifestyle, hardiness, gender role characteristics, the correlation coefficient between health promoting lifestyle and hardiness was r=-.48, p$lt;.001. Also there were significant correlation between health promoting lifestyle and gender role characteristics(r=.22, p$lt;.01), hardiness and gender role characteristics(r=-.39, p$lt;.001). 4) A stepwise multiple regression analysis was done on the total health promoting lifestyle score using the demographic variables, hardiness subscale and gender role characteristics for independent variables. A total of 25% of the variance was explained in the total health promoting lifestyle by the control, challenge and marriage satisfaction. In conclusion, hardiness and gender role characteristics were engaged in health promoting activity in midlife women.

Stroke is a crisis for the individual and family. The sudden change in health status and functional ability requires long-term care. Disability of stroke patients require early systemic rehabilitation because the efficiency of rehabilitation exercise in the acute stage after and attack of a stroke or at home after their discharge has a great influence on returns to their social life. Rehabilitation programs must include the acute ad passive exercises for the prevention of complications of muscles, skeletal or respiratory systems which can be caused by immobilization. These exercises have to be intensified to be taken continuously during the hospitalization or after the discharge. The study was designed to test the effects of rehabilitation exercise on functional outcome after stroke. The quasi-experimental study employed control group design with admission, 4weeks and 8weeks as measured on the Functional Independence Measure. Participants were assigned to the control or the experimental group, with each group having 23 participants. The experimental group participated in individual intervention that featured the active and passive exercise, whereas the control group received the routine schedule from the hospital. Data were analyzed using Fisher's exact test, ANCOVA, Repeated measure ANOVA. The result of this study are 1) No significant difference were found between the two groups on characteristics related disease and demografic data. 2) There was a statistically significant differences in the total FIM during the rehabilitation process over time(F=115.35, p<0.001) and an interaction between groups and time(F=6.17, p=0.003). However, there were no significant differences between the groups. There was no significant differences between groups in the motor FIM(F=0.04, p=0.837), but there was changes over time and an interaction between group and time(F=3.98, p=0.025 ; p=101.83, p=0.0001). In cognitive FIM, only changes over time in functional outcome were found significant difference(F=6.03, p<0.004). 3) The effect of rehabilitation exercise in functional outcome were as follows: After the 4weeks, there were no significant differences between groups in functional outcomes, but significant differences in total FIM and motor FIM occured between the two groups after the 8weeks(Z=-2.79, p<0.05 ; Z=-2.62, p<0.05). Especially, self-care item was significantly differences between groups after the 4 or 8weeks(Z=-2.71, p<0.01 ; Z=-3.67, p<0.01). This study provides the basis of nursing research for stroke rehabilitation and is useful in the application of home care. Ultimately, more rapid and cost-effective rehabilitation as well as greater functional independence can be expected for stroke patients on discharge home.
