Purpose. This study was to identify the relationship between self-directed learning and nursing student's satisfaction of clinical practice. Methods. This study was designed to measure the level of satisfaction according to the contents, guidance, environment, time, and the evaluation of clinical practice. Two hundred thirty-one nursing student from baccalaureate program in H-gun was sampled. A scale consisting of 75 questions, developed by the researcher, was used to gather data from September 14 through 27, 2012. The data was analyzed by descriptive statistics, paired t-test, pearson correlation, and multiple linear regression using the SPSS WIN 18.0 program. Results. The results were summarized : Self-directed learning didn't show a significant different by grade(t=0.83, p=.934). Nursing student's satisfaction of clinical practice didn't show a significant different by grade(t=0.26, p=.798). The relationship between self-directed learning correlated with the degree of nursing student's satisfaction in clinical practice(r=.44, p<.001). The factors of self-directed learning described nursing student's satisfaction of clinical practice as $R^2$=.215(F=9.858, p<.001). Conclusions. It was found that a higher degree of satisfaction in clinical practice depends on a higher degree of self-directed learning. Therefore, nursing faculty should plan intervention to improve satisfaction level of clinical practice by fostering self-directed learning.

평활근 수축에 대한 감초산(glycyrrhizic acid)의 효과를 연구하고자 하였고 관련 상세 기전을 결정하기 위해 glycyrrhizic acid가 agonist-sensitive하게 평활근 수축한다는 가설을 제시하였다. S/D rats의 평활근을 수조 내 준비하였고 신호 변환기에서 평활근에 의한 운동 신호가 전기적 신호로 변환되어 생리기록기에 표시되는 데이터는 일원배치 분산분석으로 분석하였다. 재미있게도, 감초산은 불화물, 트롬복산 유사체 등 굵은 미세섬유성 조절성 수축제에 의한 평활근 수축을 중등도로 억제하였고 (농도 0.01, 0.03, 0.1 mM 불화물에서 p=0.113, 0.008, 0.004 (Student's t-test), p=0.113, 0.008, 0.004 (One way ANOVA), 그리고 0.01, 0.03, 0.1 mM 트롬복산 유사체에서 p=0.156, 0.004, 0.003 (Student's t-test), p=0.156, 0.004, 0.003 (One way ANOVA)) 포볼 에스테르 등 가는 미세섬유성 조절성 수축제에 의한 평활근 수축에 대해 효과가 소실되었다 (0.01, 0.03, 0.1 mM 포볼 에스테르에서 p=0.392, 0.086, 0.065 (Student's t-test), p=0.392, 0.086, 0.065 (One way ANOVA)). 이러한 결과는 내피 기능이 억제된 평활근에서 감초산은 평활근 내피에서 EDRF (NO) 생성 효과 외에 주로 ROCK 활성 감소 등 평활근에 대한 직접적 효과를 통해 최종적으로 평활근에서 악틴-미오신 상호작용을 제한하여 평활근을 이완시키는 것으로 생각된다.

The shrinkage preliminary test ridge regression estimators (SPTRRE) based on Wald (W), Likelihood Ratio (LR) and Lagrangian Multiplier (LM) tests for estimating the regression parameters of the multiple linear regression model with multivariate Student's t error distribution are considered in this paper. The quadratic biases and risks of the proposed estimators are compared under both null and alternative hypotheses. It is observed that there is conflict among the three estimators with respect to their risks because of certain inequalities that exist among the test statistics. In the neighborhood of the restriction, the SPTRRE based on LM test has the smallest risk followed by the estimators based on LR and W tests. However, the SPTRRE based on W test performs the best followed by the LR and LM based estimators when the parameters move away from the subspace of the restrictions. Some tables for the maximum and minimum guaranteed efficiency of the proposed estimators have been given, which allow us to determine the optimum level of significance corresponding to the optimum estimator among proposed estimators. It is evident that in the choice of the smallest significance level to yield the best estimator the SPTRRE based on Wald test dominates the other two estimators.

Purpose: This study compared the effects of Static stretching and Mulligan's Two-leg rotation about the Hamstring flexibility, Hip range of motion, and pain. Methods: The subjects were allocated randomly into two groups: Static stretching group (n=13) and Mulligan's two leg rotation group (n=14). The study was designed with stretching protocols for four minutes and thirty seconds per day five times a week for three weeks in total. Measurements, including the Sit and reach test, Active/Passive Straight leg raise, and Visual analogue scale, were conducted before and after the intervention. The data were analyzed using a paired t-test and independent t-test. Results: The flexibility of the two leg rotation group was higher than the static stretching group after the intervention. The post-sit and reach test value of the two leg rotation group was significantly higher than the pre-sit and reach test value of the static stretching group. In addition, the variance of the sit and reach test of the two leg rotation group was significantly higher than that of the static stretching group. Conclusion: These results showed that two leg rotation techniques have a positive effect on the changes in the sit and reach test and active straight leg raise test. Two leg rotation techniques can be recommended as a self-stretching and easier way to stabilize the lumbopelvic rhythm, reduce the stiffness of the muscle and relieve pain. This is effective in preventing muscle damage, enabling muscle relaxation and reducing the risk of injury to the spine during daily lives and in sports activities.

The study tried to develop a parent-involvement sex education program and find out its effects for more effective sex education methods for high graders of a primary school. The subjects were recruited from 5 classes of 6th graders in Y Primary School in N city, Kyeonggido province, South Korea. Data collection was done from October 4, 2003 to November 7. The experimental group consisted of 43 students from 3 classes with the help from class teachers and parents' involvement in the program. The control group consisted of 43 students randomly sampled by computer from the other two classes. For the experimental methods, the experimental group was given a parent-involvement sex education program as well as a student sex education program: the control group only received the student sex education program. The results were analyzed according to frequency, percentage, $x^2$-test, fisher's exact test and t-test using SAS program. As a result of the homogeneity test, both the groups proved to be the same (t=-0.29 p=0.77, t=0.49 p=0.62) in preliminary sex-attitude and sex-related communication frequency score. But the two group showed meaningful differences (t=2.52 p=0.01, t=2.04, p=0.04) in preliminary sex-knowledge and sex-related communication quality score. After the sex education programs, the two groups didn't show meaningful statistic differences(t=-0.42 p=0.68, t=1.57 p=0.12) in preliminary sex-knowledge and sex-related communication quality score. But the experimental group was statistically more meaningful (t=2.16 p=0.03, t=4.86 p<0.0001) in the difference of sex attitude and sex-related communication frequency than the control. The parent-involvement sex education program developed in this study was more effective for improving their sex attitude and for increasing the frequency of their sex-related communication with parents than the existing student program. Therefore, for sex education, it's necessary to develop and spread various programs where parents can be involved.

Purpose: This study investigated the effects of reeducation of nursing process on nurses' expertise, critical thinking disposition, and clinical decision making. Methods: Data were collected from March to June, 2007. The subjects were 47 Academic Credit Bank System Student Nurses. They were taught 'nursing process' during 1 semester(15weeks). 47 nurses were divided into three groups according to clinical experience(under 3 years, 3 to under 5 years, 5 years or more). After 15 weeks, the effects of education were compared using a paired t-test between pre-test and post-test. Results: There was a significant difference in the 3 to under 5 years experienced nurses's expertise(t=-3.659, p=.004) between the pre-test and post-test. There was a significant difference in the 5 years or more experienced nurses's expertise(t=-5.781, p<.001) and critical thinking disposition(t=-3.345, p=.003) between the pre-test and post-test. There were no significant differences in clinical decision making(accuracy, proficiency, and confidence) of 3 groups. Conclusion: Reeducation of nursing process is a valuable teaching and an evaluation strategy for 5 years or more experienced nurses to improve expertise and critical thinking disposition. We need to develop continuing education program for improving nurses' clinical decision making.
