  • Purpose: The purpose of this is to identify the relationship among the age, body mass index(BMI) and exercise frequency(EF) with knee joint position sense in korean healthy women. Methods: Healthy women of 328 who participated in this study were tested knee joint position sense; reposition error was measured with a Myrin goniometer. Each reposition error was analyzed using descriptive statics, pearson correlation coefficients, and stepwise multiple regression. Results: The mean reposition error by age groups was significant decrease getting older. The mean reposition error by BMI groups was significant decrease getting higher. And the mean reposition error by EF groups was significant decrease getting lower. The knee joint position sense showed a significantly correlation with age(r=0.36, p=.00), BMI(r=0.34, p=.00) and EF(r=-0.50, p=.00). The most powerful predictor of knee joint position sense was EF. The reposition error according to stepwise multiple regression is $3.36+(-2.64){\times}EF+0.13{\times}age$, and account for 46%($R^2=0.46$) of the variance in the knee joint position sense. Conclusion: The older the women are, for prevent of knee injuries due to decreased joint position sense, regular exercise is essential factor.

  • Purpose: The purpose of this study was to describe the status of the functional health literacy of the elderly living in a rural community and to identify the influencing factors on the functional health literacy. Methods: Subjects(n=238) aged over 60 years were selected for data collection. Functional health literacy was measured by Korean Health Literacy, which consisted of 15 items including eight numeracy and seven comprehension items. Descriptive statistics, t-test, ANOVA with Scheffe test, and stepwise multiple regression were used to analyze the data. Results: The mean score of total functional health literacy was $6.66{\pm}3.31$, numeracy was $3.52{\pm}1.76$, and comprehension was $3.41{\pm}2.10$. Of the subjects, 39.1% showed a low score below the median split. In the results of stepwise multiple regression, the factors affecting functional health literacy were basic literacy, age, number of chronic diseases, self-reported health status, and gender. These factors accounted for 33.0% of functional health literacy. Conclusion: These results suggest that interventions for improving functional health literacy are necessary to enhance elders' ability of self-care management. In addition, it is needed to take into account the individual characteristics of the subjects depending on their gender, age, and health status.

  • Purpose: This study was conducted in order to define factors influencing learned helplessness in undergraduates. Independent variables including external entrapment, internal entrapment, social support, trait anger, state anger, and anger expression were used to predict learned helplessness. Methods: Data were analyzed using the SPSS/WIN 20.0 program for descriptive statistics, Pearson correlation coefficients and stepwise multiple regression. A total of 241 undergraduates recruited from September to November 2012 were included in the study. Results: Four factors of learned helplessness were founded to show significant correlation with external entrapment, internal entrapment, social support, trait anger, state anger and anger expression. Stepwise multiple regression analysis showed that 64% of the variance in learned helplessness was significantly accounted for by internal entrapment, social support and anger expression. Conclusion: This study showed that perceived entrapment and social support are important predictors of learned helplessness. Therefore, in order to reduce learned helplessness in undergraduates, it is necessary to design an intervention program with strategies to help in coping with and reducing perceived entrapments.

  • Applying the data from 64 single(26 men and 38 women) and 71 childless married men and women(37 men and 34 women) aged between 30 and 45, this study is to understand their future fertility intention. For this purpose, ideal and real number of children that participants plan to have were compared using paired t-test. Second, demographic variables(sex, age, marital status), child care related variables(thoughts about caring children, child care value), individual characteristics(gender role attitude, relation orientation) and social context variables(perceived economic condition, recognition of low fertility policies) were included in a stepwise regression model to explain expected number of children participants plan to have in the future. Results showed that ideal number of children participants wish to have was significantly higher than real number of children they expect to have in the Korean society. The stepwise regression model explained 35% of the variance of the dependent variable. Among four types of variables, child care related variables most powerfully explained expected number of children study participants plan to have in the future. Finally, age, child care value, gender role attitude, and relation orientation significantly explained expected number of children in the future.

  • The purpose of this study is to investigate the effect of parenting behavior and parent-child communication on internet use among school-aged children. The subjects were 215 children whose grade are 3rd and 5th selected from an elementary school in Incheon. The statistics used for this data were t-test, one-way ANOVA(Duncan's test), and stepwise regression. The findings from the present study suggested that academic achievement and birth order turned out to be significant variables on children's internet use, except for sex and grade. Results of the stepwise regression analyses that the etiologic model of this study was more proper, and parenting behavior is more effective variable than parent-child communication in predicting internet use among school-aged children. Implications based on this study are as follows; In order to decrease the degree of school-aged children's internet use, parents should do less permissive parenting behavior and problematic communication with their children.

  • Purpose: The purpose of this study was to investigate factors affecting trait anger level in undergraduate students. Methods: The participants consisted of 315 undergraduate students at the universities in the P and D cities. Data were collected with a structured questionnaire and analyzed using descriptive analysis, t-test, ANOVA, Pearson correlation coefficients, and multiple stepwise regression with the SPSS/Win 20.0 program. Results: The low trait anger group showed lower levels of anger-out, anger-in and depression compared to the high trait anger group. The anger-control and positive thinking were higher in the low trait anger group than that of high trait anger group. The result of multiple stepwise regression showed that both depression and anger-out were predictors in trait anger in the both groups. In the low trait anger group, anger-control, anger-in, depression, and anger-out were significant factors of trait anger, which accounted for 31% of the total variance. High trait anger level was affected by depression, anger-out and positive thinking, which explained 40% of trait anger. Conclusion: The results of this study suggest that anger management program for undergraduate students should consider trait anger level as well as approaches with customized strategies according to trait anger level.

  • To determine factors affecting self-care behavior of diabetics, the relationships of hardiness, family support, demographic and medical variables to self-care behavior were investigated in 180 samples with non-insulin dependent diabetes mellitus. In stepwise multiple regression analysis, 26.76% of the variance in self-care behavior was accounted for by family support(15.52%), age(7.76%), and clinical history (2.07%). To compare the magnitude of predictor's significance by gender, stepwise multiple regression was conducted seperatively by gender group. In the male sample 25.22% of the variance in self-care behavior was accounted for by family support, age, and challenge. In the female sample family support, age, and committment were significant predictors in self-care behavior with 28.82% of the variance. The results highlight the value of family support in self-care behavior in diabetics regardless of gender difference. According to the finding of this study, family support is the most significant predictor of self-care behavior in NIDDM. This implicates that in future diabetic care, a family member should be encouraged to participate in the patient education process. Also as hardiness is not supported by a unidimensional construct, more empirical studies are recommended to differentiate the conceptual traits for the three subconcepts of hardiness.

  • This study was undertaken in order to examine the effect of hardiness on stress-causing factors, defined in this study as burnout in nursing. The subjects were 248 nurses working in three general hospitals in Taejon. The instruments used for this study were a survey of general characteristics, modified Health-Related Hardiness Scale(HRHS) (25 items), job stress scale (63 items), and burnout scale (20 items). Analysis of data was done through the mean, percentage, Pearson correlation coefficient, and stepwise multiple regression done with a SAS program. The results of this study are as follows. 1) The average item score for the job stress was high at 4.44. In the subcategories, the highest degree of stress was night duty(5.11), and work overload(4.70), responsibility for extra affairs(4.70), conflict in nurse-doctor relationships(4.69), and low reward(4.63) in that order. 2) In the stepwise multiple regression analysis, hardiness(11.55%) was a significant determinant of burnout along with job stress(17.24%) and job duration(12.94%). The results of this study show that hardiness has an effect on psychological distress caused by stress.

  • Purpose: The purpose of this study was to identify factors influencing maternal identity of Korean primiparas. Methods: The data were collected by a self-report questionnaire in 2006. The participants were 210 healthy primiparous women who delivered at one of three medical centers and revisited the outpatient department for follow up between 4 to 6 weeks after childbirth. Data were analyzed using the SPSS WIN 17.0 program with descriptive statistics, t-test, one way ANOVA, Pearson correlation coefficient, and stepwise multiple regression. Results: Maternal identity was significantly correlated with Taekyo accomplishment, the culturally based prenatal preparation (p<.001). Transitional gratification to motherhood (p<.001), postpartum depression (p<.001), childcare stress (p<.001), infant temperament (p<.001), and social support (p<.001) were also significantly correlated with maternal identity. The stepwise multiple regression analysis showed that maternal identity was significantly predicted by transitional gratification to motherhood, infant temperament, childcare stress, and Taekyo accomplishment. These variables explained 31.0% of the variance of maternal identity. Conclusion: The results of this study suggest that postpartum nursing interventions to promote maternal identity should focus on reinforcing education and support for reducing childcare stress and infant difficulty, and increasing transitional gratification to motherhood. Also, prenatal encouragement and education for improving Taekyo accomplishment may be helpful to promote maternal identity after birth.
