Many students have misconceptions that upward direction force act on the object which is moving upward after being thrown vertically upward, and no force act on the object at the top of its flight because the object stop or don't' move at the top. To change these misconceptions, in this study, deductive reasoning tasks were used, and student's responses to the tasks were analyzed. In the first part of this study, student's prior conceptions about force and motion and student's deductive reasoning abilities were investigated. And the second part, student's explanations were classified to either the premise-based or idea-based explanation. In the case of the object which is moving upward, 62% of students who had misconception changed their misconceptions to physically correct concept, but, only 24% of students changed their misconceptions for the object at the top. For the first task, more students changed their misconceptions when they made responses based on premises than based on their own idea(p<.05), so, the first task can be helpful for conceptual change. 40% students changed their own misconception by reasoning deductively based on premises provided in the first task, but only 17% students changed by the second task. Student's reasoning abilities investigated in the first part of this study did not affect the conceptual change. Four students for the first task and one student for the second task did not change their misconception even though they made premise-based explanation and had high reasoning abilities.

This study is to set up a model of minimum and optimum standards for college and university library building areas in Korea. The results of this study are summarized as follows: 1. minimum standards(proposal) At first, Areas needed by factors of space component are as follows: User space --- 0.45 $m^{2}$ per student. Collection space --- 0.0107 $m^{2}$ per volume Staff space --- 10.1 $m^{2}$ per person Space attached to user, collection and staff space --- 5% of the sum of user, collection and staff areas(0.041 $m^{2}$ per student). Nonassignable space --- 25% of the sum of user, collection and staff areas (0.21 $m^{2}$ per student). Next, the formula to calculate the total area of the college and university library building is as follows: N = 0.45T $m^{2}$(a) + 0.0107V $m^{2}$(b) + 10.1S $m^{2}$(c) + 0.05(a+b+c) $m^{2}$, NS = 0.25N $m^{2}$. 2. Optimum standards(proposal) At first, Areas needed by factors of space component are as follows: User spae --- 0.64 $m^{2}$) per student. Collection space --- 0.01 $m^{2}$ per volume Staff space --- 9.7 $m^{2}$ per person Space attached to user, collection and staff space --- 5% of the sum of user, collection and staff areas(0.073 $m^{2}$ per student). Nonassignable space --- 25% of the sum of user, collection and staff areas(0.38 $m^{2}$ per student). Next, the formula to calculate the total area of the college and university library building is as follows: N = 0.64T $m^{2}$(a) + 0.01V $m^{2}$(b) + 9.7S $m^{2}$(c) + 0.05(a+b+c) $m^{2}$, NS = 0.25N $m^{2}$.

Purpose: This study was done to examine the effect of direct practice of newborn health assessment on nursing student's clinical competence and self-efficacy and to propose effective strategies for clinical education on newborn care. Methods: Design was a nonequivalent control group quasi-experimental study. The direct practice program was composed of a lecture, demonstration, drill and feedback using a manikin, and repeated direct practice regarding newborn health assessment. Participants were 65 student nurses taking the pediatric nursing practicum in the nursery room at M hospital. The experimental group (n=33) participated in the direct practice program for newborn health assessment and the control group (n=32) received the traditional practice method. Nursing clinical competence was assessed by two nurse investigators and structured questionnaires were used to measure self-efficacy. Results: The experimental group's clinical competence was significantly higher than that of the control group (t=-4.82, p=.000). However no significant difference was found between the two groups for self-efficacy (t=1.264, p=.211). Conclusion: These findings indicate that the direct practice program is effective in improving nursing student's clinical competence, but it was not effective in increasing self-efficacy. Direct practice in various clinical education settings is recommended and longitudinal effects be evaluated.

This study discusses the traditional costume of Korea and Japan and cognitive factors affecting its recognition by conducting a survey on both Korean and Japanese students so that comparative analysis of the differences about whether to rent or own traditional costume and about whether the students surveyed have visited the other country reciprocally, can be made to set the future course of the traditional costume which have gradually been worn less frequently and favored by less people. College students of Japan and Korea were chosen for this study and asked to fill in a questionnaire. 491 respondents were analyzed using SPSS10.0 for frequency analysis, factors analysis and t-test. Findings of this study are as follows: Firstly, there were 7 factors affecting the Korean student's recognition of Hanbok while 6 factors involved in Japanese student's recognition of Kimono. Korean students thought highly of the traditional costume and yet had less knowledge of it compared to the Japanese students. Secondly, analysis of the student's recognition of their counterpart's traditional costume showed that there were equally 4 factors affecting the student's recognition. Students found the traditional costume difficult to wear and uncomfortable when worn. Japanese students regarded Hanbok as an abstract form of the traditional Korean culture while Korean students viewed Kimono as a realistic form of something concrete. Thirdly, analysis of the differences about the recognition based on the student's owning or renting the traditional costume. or visiting the counterpart's country, showed that students owning the traditional costume were more positive about the traditional costume and well versed in it. And students having visited their counterpart's country thought more favorably of the traditional costume of their counterpart.

In children, dental anxiety of dental treatment has been recognized as a source of problems in patient man agement for many years. Dental anxiety can be causes of negative cooperation, cancel and avoid of dental treatment. Therefore, dentist and dental team should recognize of child's dental anxiety as early as possible and manage appropriately. In previous studies, it is reported that parental dental anxiety affect dental anxiety and cooperation of their child. And it is parental decision which results in a child's visit to the dentist, rather than a child's decision in most cases. Therefore, it is important to identify the relationship of dental anxiety between child and parent. We estimated child's dental anxiety before dental treatment using Venham Picture Scale that is useful even a very young child and parental dental anxiety using Corah's dental anxiety scale. Then, two values above were compared. Child's cooperation, temperament, sex, age, parental education were estimated and compared with dental anxiety, too. The results were as follows: 1. There are positive relationship of dental anxiety between child and parent with the correlation analysis(P<0.02). 2. There are negative relationship of child's dental anxiety and child's cooperation with the correlation and regression analysis(P<0.001). 3. Low anxiety group has lower mean value of four temperament item with the Student's t-test. But, there is no statistical differences(P>0.1). 4. Girl and younger group have higher mean value of dental anxiety than boy and older group with the Student's t-test(P<0.001). 5. Low educated parents have higher mean value of dental anxiety than high educated parents with the Student's t-test(P>0.1).

The study investigates the effects of online instructional facilitator's qualities on student performance of online class activities. The study explores the roles of instructional facilitators who may influence student performance of online class activities and their academic achievement. The study employs a set of aggregated data from 1,362 subjects and 10 facilitators who participated in multiple online classes. The results of independent samples t-test reveal that the student performance in online classes has no association with facilitators' educational background or academic degree, as well as demographic characteristics, student evaluation records and instructional achievement. The results of multiple regression analysis show that the facilitator engagement has a positive relation to the enhancement of student interaction, reading discussion messages, and the quality of discussion messages in online discussions. The results of correlation analysis show that the facilitator engagement has a positive impact on both increasing the number of reading discussion messages and enhancing the quality of discussion messages. The facilitator engagement increases the quantity of reading discussion postings and enhances the quality of discussion messages, which would be a substantial contribution to student performance by facilitators. The findings suggest that student performance and academic achievement in online classes are not independent of facilitator engagement.

The purpose of this study were to investigate and no investigate and to compare perceptions of home economics teachers and educators regarding home economics student teaching pratice, thereby to provide fundamental information for improving home economics student teaching pratice. The specific objectives of this study were at follows. 1. To determine and compare the perceptions of home economics teachers and teacher educators regarding the importance and achievement of (1) the objectives of student teaching, (2) the experiences of student teaching, (3) procedures for selecting cooperating teachers, (4) roles and responsibilities of cooperating teachers, and (5) roles and responsibilities of university supervisors. 2. To identify problems and revisions about home economics student teaching pratice suggested by home economics teachers and teacher educators. The subjects in this study included 90 home economics teachers in 500 girls’middle schools and 13 teacher educators in 21 universities with home economics education department in Korea. For this study, the Habedi’s instruments were used through testing validity and reliability. The data of this study were analyzed by using mean, standard deviation, t-test, and content analysis. The results of this study were as follow；1. The areas with the difference of perceptions of the importance between the two groups were objectives of student teaching, experiences of student teaching, procedures for selecting cooperating teachers, and roles and responsibilities of cooperating teachers. 2. Regarding problems about home economics students teaching practice, home economics teachers indicated difficulty in performing adequate student teaching because of reduction in class hours, and lack of student teachers’positive attitude in performing student teaching, while teacher educators indicated having reluctancy of cooperating school to admit student teachers, and difference in experiences of student teachers because of disparity among cooperating schools. As solutions about the problems of home economics student teaching practice, home economics teachers suggested that student teaching course should be limited to the students qualified for teaching and that class observation and teaching practice in real class should be emphasized, while teacher educators suggested that student teaching should be performed adequately by providing institutions to control student teaching practice teacher should be made efficient by examining the scales of cooperating schools.

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.
