Purpose: The purpose of this study was to identify the relationship of clinical competency and self-directed learning in nursing students. Method: This study was conducted at two nursing colleges with students in a 2 year undergraduate nursing program. Data were collected from 182 students by means of self reporting questionnaires from October 1 to October 8, 2004. The data were analyzed by SPSS 10.0 PC programs using descriptive statistics, one-way ANOVA, Pearson correlation coefficient. Result: The questionnaire of students' clinical competency consisted of nineteen items based on a five point summated rating scale and was categorized into six subscales by factor analysis. The six subscales are nursing process, major nursing intervention, education for clients, observation and physical examination, and fundamental nursing. The more adaptable to major, the higher clinical competency (F= 3.406, p= .035) and self-directed learning (F= 7.444, p= .001). There was a positive correlation between students' clinical competency and self-directed learning (r= .367, p= .001). Conclusion: we concluded that future research should explore strategies for the development of self-directed learning to improve clinical competency of nursing students.

Purpose: On the basis of the theoretical framework of a combination of Roy's adaptation theory and Lazarus & Folkman's theory of stress - appraise coping, the purpose of this study was to predict effect factors of adaptation to university life of Chinese international students in Korea. After this, a model of adaptation to university life of Chinese international students in Korea was constructed. Methods: A questionnaire was used to survey 369 Chinese international students from one university in Korea, which was analyzed by using PASW Statistics 18.0 and LISREL 8.7. Results: This theoretical model explained adaptation to university life of Chinese international students at 75.0% in Korea. Physical symptoms, loneliness, acculturation stress and self-efficacy directly affected the adaptation to university life. Korean language proficiency indirectly affected adaptation to university life through self-efficacy. Conclusion: Results of this study provided theoretical basis for the future health care of university- centered health centers. For improving adaptation to university life of Chinese international students in Korea, education and nursing measures for reducing physical symptoms, loneliness and acculturation stress, and improving Korean language proficiency and self-efficacy are proposed for further research and development.

The purpose of this study is to improve the learning ability of probability/statistics for H/W majors. Firstly, we developed a teaching method coupling probability/statistics with programming and multimedia signal processing courses that are opened in the H/W major curriculum. By use of its teaching-learning, we tried to verify the effectiveness on the improvement of learner's academic achievement and then analyze its educational efficiency through the regression analysis. Secondly, by analyzing the surveys and the statistical results of the education cases, we proposed a management plan on efficient teaching-learning in order to cultivate the learning ability of probability/statistics at a future time. Lastly, we concluded that probability/statistics is a required course of learners so as to contribute for the advanced technical development and the enhanced competitiveness in the field of the H/W.

This paper suggests the optimal periodic preventive maintenance policies after the combination warranty is expired. After the combination warranty is expired, a repairable system undergoes PM periodically and is minimally repaired at each failure. And also the system is replaced by a new system at the N th PM. In this case, we derive the mathematical formula for the expected cost rate per unit time. The optimal number and period for the periodic PM that minimize the expected cost rate per unit time are obtained. Some numerical examples are presented for illustrate purpose.

Purpose: The purpose of this study was to provide basic data for the development of health and safety programs by examining child-care teacher's knowledge, self-confidence and practice concerning the health and safety of children under their care. Method: The participants were 72 teachers from 15 child care centers in Seoul City and Chung-Nam Province. Data were collected using self-report questionnaires. Data were analyzed using descriptive statistics, ANOVA and Pearson correlation coefficients with SPSS 12.0 Win program. Results: The mean score for self-confidence was lower than knowledge and practice. Self-confidence score about emergency care for falls, fractures and resuscitation were lowest. For safety knowledge, scores about facility and environment were lowest. For health knowledge, scores about disease and symptoms were lowest. For practice, scores about seat belts and safe furniture arrangement were lowest. Significant correlations were found between practice and self-confidence. There were significant differences in the degree of knowledge according to education, and in practice according to age. Conclusions: Health and safety education programs for child care teachers are necessary for the promotion of knowledge, self-confidence and practice in health and safety. The results suggest that health and safety education program should be provided systematically and continuously for child care teachers.

The purpose of this paper is to study some properties of quasi-submaximal spaces and related examples. More precisely, we prove that if X is a quasi-submaximal and nodec space, then X is submaximal. As properties of quasi-submaximality, we show that if X is a quasi-submaximal space, then (a) for every dense $D{\subset}X$, Int(D) is dense in X, and (b) there are no disjoint dense subsets. Also, we illustrate some basic facts and examples giving the relationships among the properties mentioned in this paper.
