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.

Purpose: The purpose of this study was to identify the factors affecting sleeping patterns among hospitalized elderly. Methods: A descriptive correlational study was conducted. Participants were 121 hospitalized elderly in a hospital located in a county. A structured questionnaire was used for data collection. Collected data were analyzed using descriptive statistics, t-test, one-way ANOVA, Pearson's correlation, and stepwise multiple regression. Results: Almost a half of hospitalized elderly in this study suffer from sleep disturbances. As results of univariate analyses, physical symptoms, anxiety, depression, and environmental factors disturbed sleep among hospitalized elderly. However, the result of stepwise multiple regression analysis identified that anxiety and environmental factors were significant predictors of sleeping patterns for hospitalized elderly and these two factors accounted 32.5% of variance of sleeping patterns among hospitalized elderly. Conclusion: Sleep assessment should be conducted on admission to identify sleep difficulties and thereby to improve quality of nursing care. Nurses and other health care personnels should make efforts to decrease anxiety and to eliminate environmental barriers of sleep among hospitalized elderly. Educational programs for nursing staff that offer information about sleep and sleep promoting interventions for the elderly patients are critical. Moreover, sleep promotion intervention program should be developed, applied and evaluated.

Objectives: The purpose of this study was to examine factors influencing the mental health of high school students in relation to sociodemographic variables, family function, self-esteem, social support, and self-identity. Methods: The survey was carried out on a convenience sample of 332 high school students. Data analysis procedure included stepwise regression using mental health as the dependent variable, and sociodemographics, family function, self-esteem, social support, and self-identity, as independent variables. Results: Stepwise multiple regression revealed that the factors such as self-esteem(${\beta}=0.422$, p<0.001), self-identity(${\beta}=0.166$, p<0.001), and sex(${\beta}=-0.165$, p<0.001) turned out to be significant affecting factors. Twenty seven percent of varience in mental health was explained by these factors(22% of varience by self-esteem). Conclusion: Self-esteem was turned out to be the most important effective factor of mental health in high school students. These results suggest that it is important for high school students to promote their self-esteem to keep their good mental health.

The purpose of this study was to analyze the relationship between maternal attachment and discharge against advice in high risk infants and determine the factors which affect discharge against advice. Data of this study were collected by means of reviewing the medical records of 127 in-patients who were diagnosed as high risk infants in admission and interviewing of the mothers of these patients was done by telephone. The high risk categories were neonatal hyperbilirubinemia, congenital anomaly, congenital heart disease, blood disorder, neonatal infection and birth injury. Maternal attachment was measured by deviding the subjects into 2 groups, the one the continuing treatment group and the other the discharge against advice group. Maternal attachment is determined by an interplay of maternal attitude and specific infant behaviors. Maternal attachment developes through continuous physical and psychological contact between mother and infants. Later it developes into maternal love. The results were as follows: 1. There was a significant association between maternal attachment and discharge against advice, that is, the attachment score was higher in the continuing treatment group. 2. Inspite of controlling medical insurance, severity of disease and the length of stay, it was found that there continued to be either a partially significant or fully significant relationship between maternal attachment and discharge against advice. Stepwise multiple regression revealed that maternal attachment was second in importance as a predictor of discharge against advice, which indicates that maternal attachment was a significant predictor of discharge against advice. 3. Stepwise multiple regression revealed that in 32.3％ of these cases the significant predictors of discharge against advice were length of stay, maternal attachment, delivery type, feeding type and income.

대부분의 대학들은 교수업적평가를 위해 강의평가제도를 실시하고 있다. 그러나 강의평가의 결과는 강좌규모, 강의형태, 개설학년, 이수구분, 평균평점 등과 같은 개설강좌의 특성에 많은 영향을 받게 된다. 따라서 이러한 각 강좌특성들이 강의평가 결과에 영향을 미치는 효과를 제거하지 않는다면, 담당교수가 강의평가 결과에 대한 공정성과 객관성을 신뢰할 수 없게 만들 정도로 심각한 편의를 갖게 된다. 따라서 강의평가의 공정성을 위해 강좌특성에 따른 편의를 제거하기 위한 사후조정된 점수가 요구된다. 따라서 본 연구에서는 단계적 변수선택법에 의한 회귀분석을 이용하여 강의평가 결과에 대한 균등화 방법을 이용하여 사후조정된 점수를 계산하는 방법을 제안한다. 그리고 제안된 방법은 기존의 방법과 비교를 하였다.

The primary objective of this study is to investigate the feasibility of an innovative surface-mount sensor, made of a piezoelectric disc (PZT sensor), as a consistent source for surface wave velocity and transmission measurements in concrete structures. To this end, one concrete slab with lateral dimensions of 1500 by 1500 mm and a thickness of 200 mm was prepared in the laboratory. The concrete slab had a notch-type, surface-breaking crack at its center, with depths increasing from 0 to 100 mm at stepwise intervals of 10 mm. A PZT sensor was attached to the concrete surface and used to generate incident surface waves for surface wave measurements. Two accelerometers were used to measure the surface waves. Signals generated by the PZT sensors show a broad bandwidth with a center frequency around 40 kHz, and very good signal consistency in the frequency range from 0 to 100 kHz. Furthermore, repeatability of the surface wave velocity and transmission measurements is significantly improved compared to that obtained using manual impact sources. In addition, the PZT sensors are demonstrated to be effective for monitoring an actual surface-breaking crack in a concrete beam specimen subjected to various external loadings (compressive and flexural loading with stepwise increases). The findings in this study demonstrate that the surface mount sensor has great potential as a consistent source for surface wave velocity and transmission measurements for automated health monitoring of concrete structures.
