The Korean National curriculum is divided into the curriculum, discretion, and extra curriculum activity. Extra curriculum among them consists of fie grounds, that is, a self-governing, adjusting, developing, service and exercise activity. The content of developing activity among them includes academic literary arts, in that the developing activity related to science. The developing activity connected with science can be a good chance which students can have deepened learning besides a regular course. In addition, effective management in science class can play an important role to cultivate scientific sense and to raise scientific talent. The study finds out how the management connected with science-related extra-curricula activity in science is actually going on. The study carries out a questionnaire with 40 teachers and interviews 5 teachers as well who are in charge of science-related extra-curricula activity connected with science. As a result, on the side of students, ① systematic introduction course in science is not given to them, ② the course is operating without considering students interests and levels, so it causes the problems of developing their potential ability and extension. On the side of teachers, ① they organize the science department based on school's situation and policy. ② they disregard teachers' roles and interests. ③ the science department's program is operating improvisedly rather than systematically, ④ the evaluation is done formally is found out. I have come to know that to manage a desirable science-related extra-curricula activity connected with science needs to have sufficient, detailed materials and experts from outside.

Purpose: This study was designed to find differences between physical activity and health-related factors of Korean male adults. Methods: Using the 2010 Korean National Health and Nutrition Examination Survey (NHANES V-1), the data of 1,876 Korean males over 30 years old who completed the Health Interview, Health Behavior Surveys and International Physical Activity Questionnaire (IPAQ) were analyzed. Analysis of differences in physical activity according to socio-demographic factors, physical health-related factors and psychological health-related factors was tested using the F-test and chi-square test with SPSS 12.0. Results: The high physical activity group was merely 2.5% and the moderate group was 51.4%. In each group, the study showed significant differences in age (p=.017), education status (p=.019), and economic status (p=.032) of socio-demographic factors, in body mass index (p=.003), vitamin D (p=.020) and hypertension status (p=.007) of physical health-related factors, and in recognition of stress (p=.027) of psychological health-related factors. Conclusion: These results revealed that physical activity can play an important role in nursing intervention of physical and psychological health-related factors in male adults.

본 연구의 목적은 학생들의 과학관련 진로 선택과 관련된 주요 요인들 사이의 인과 관계를 규명하여, 학생들의 과학진로 선택과정을 잘 설명할 수 있는 모형을 찾는 것이다. 요인 분석을 통하여 과학관련 진로 선택과 관련된 주요요인으로 과학 관련 진로에 대한 인식, 과학 학습에 대한 선호, 과학 관련 활동에의 참여 등 세 요인을 선정하였다. 구조방정식 모형을 통한 공변량 구조분석이 가능하도록 과학관련 진로 선택 요인을 알기 위한 설문지를 문헌연구와 예비검사를 통해 개발하였다. 연구대상은 서울 지역의 초등학교 6학년, 중학교 3학년, 고등학교 2학년 등 전체 947명으로, 학년별 남녀별 학생 수는 거의 같게 구성하였다. 과학관련 진로 선택의 주요 요인들 사이의 인과 구조를 설명하기 위하여 구조 방정식 모형을 통한 공변량 구조 분석의 결과, 이론 모형을 수정하여 자료와 잘 맞는 4가지 모형을 얻었다. 네 수정모형 모두에서, 과학 관련 진로 선택에 직접 영향을 미치는 것은 과학 관련 진로에 대한 인식이었고, 과학학습에 대한 선호와 과학 관련 활동 참여는 간접적으로 영향을 미쳤다. 적합도 지수가 가장 좋은 모형에 의하면, 과학 관련 진로 선택에 대하여, 과학 관련 진로에 대한 인식은 0.82의 직접 효과와 0.21의 간접 효과를 합한 1.03의 전체효과를 주고, 과학학습에 대한 선호는 과학 관련 활동 참여에 영향을 주면서 0.65의 간접 효과를 주고, 과학 관련 활동 참여는 과학 관련 진로 인식에 영향을 주면서 0.79의 간접 효과를 주었다. 학교의 과학 교육에 대한 시사점으로는 더 많은 학생들이 과학 관련 진로를 선택하게 하려면, 과학관련 진로인식을 높이도록 하는 것이 가장 큰 효과를 줄 수 있으며, 다음으로는 다양한 관학관련 활동에 참여하도록 하는 것과 과학학습에 대한 선호를 높이도록 하는 것이 효과적이라 할 수 있다. 과학관련 진로선택 과정을 더 잘 설명하기 위해서는, 과학관련 진로 선택 요인들을 더욱 포괄하는 모형의 구축이 필요하여, 연구대상을 과학고 학생들이나, 과학기술계 대학생들로 하여 구조방정식 모형을 검증하고 보완할 필요가 있다. 과학관련 진로 선택에 영향을 주는 요인들을 고려한 과학진로교육 프로그램을 개발하여 투입하고 그 효과를 검증하는 연구가 필요하다.

Purpose: This study was designed to explore the levels of physical activity and fatigue among nurses and to identify the relationship between these variables. Methods: Participants were 89 nurses working at an intensive care unit and an operating room in a children's hospital. Data were collected using self-reported questionnaires including the International Physical Activity Questionnaire and Brief Fatigue Inventory. Results: Most of the nurses' physical activity was work related, and there was a significant difference according to the working unit. Nurses with higher work stress and lower job satisfaction showed higher levels of fatigue than their counterparts did. Work-related physical activity and the interference of fatigue with relationships were related positively, whereas transport and leisure time physical activity were negatively related to usual fatigue and the interference of fatigue with life enjoyment. Conclusion: The levels of physical activity and fatigue of nurses were higher than those observed among other populations. The appropriate level of physical activity for these nurses needs to be investigated carefully. Also, in the intervention for nurses' fatigue, their level of work-related and leisure-time physical activity should be considered separately, and their work environment and psychological satisfaction level should be included.

This study investigated the academic achievement of science and high school students according to the characteristics of R&E activities in mathematics and science. In addition, based on the survey results, the correlation between R&E activity characteristics and mathematics and science academic achievement was studied through correlation analysis and factor analysis between subjects. There was a difference in academic achievement in mathematics and science according to the characteristics of the R&E activity area, and the experience of R&E activity was found to be closely related to the academic achievement of related subjects. Depending on the area of R&E activity, mathematical and scientific academic achievement was found to be two factors: mathematical logic and natural understanding. Natural understanding factors significantly influenced students' academic achievement in mathematics, physics, and life sciences, and mathematical logic factors significantly influenced the academic achievement of students in chemistry and earth science subjects. In particular, mathematical logic ability was concentrated in excellent physics class students, and natural understanding ability was concentrated in excellent life science class students. Since the characteristics of the R & E activity area greatly influence the academic achievement of mathematics and science, it will significantly contribute to the selection and operation of the R & E activity area of science high school students.

This study is to consider hypotheses with integral view on the respect of creative thinking. Subjects of this study are Korean students in the 5th grade who participated in the Field Trip Contest of the second Korean Youth Science Festival, an openended inquiry investigation. Objectives of this study are as follows: 1) to measure the inquiry level of the Field Trip Contest activity 2) to find how many hypotheses were made on different types in the inquiry investigation 3) to measure the quality level of hypotheses made in the scientific inquiry investigation 4) to find out the correlation between the 1st and 2nd hypotheses and the final activity score in the two staged scientific investigation In the consequence of it, inquiry level of the Field Trip Contest was very high with good activity topics and openended way of investigation. Hypotheses were made in the prediction, plan, and conclusion parts in the field trip activity report. They used hypothesis-as-prediction typed statements(3.41/team) more than hypothesis-as-explanation(1.28/team) and descriptive hypothesis(0.03/team) types. Content-related hypothesis(5.03/team) and process-related hypothesis(6.16/team) were usually coupled each other. Most of them had difficulties in hypothesis-from-evidence(0.31/team, 10/32 teams) in the comparison of hypothesis-from-simple conjecture(10.62/team). The quality level of content-related hypotheses(0.74point/statement) and process-related hypotheses(1.98point/statement) were very low by the hypothesis-quality scale(Quinn and George, 1975) for the content-related hypotheses and the process-related hypothesis quality scale developed in this study. There was considerable correlation between the activity score and the 1st and 2nd hypothesis in the 2 staged inquiry investigations with the 2nd and 3rd topics($0.41{\ast}$, $0.59{\ast}{\ast}$ repectively).

The purpose of this study is to introduce the science-play in the regular class, stimulate the student's curiosity, motivate them and take active part in their science class. To make an effective science class, we developed the science-play activity instead of experiments in the text, and applied it to the class. The experimental group has statistically meaningful results in the science process skills, expecially in subordinate elements such as observation, deduction, expectation, data analysis and assumption establishments(p<.01). However, the comparative group has no meaningful results in the science process skills. Though the average value of the science related attitude in the experimental group had only a little increase and had no statistically meaningful results, that in the comparative group has decreased during the same period. As for the experimental group, the science-play activities were repeated and their science related attitude has increased a little. Even though there were no meaningful statistic results(p>.05), the science-play activity was effective in the science related attitude. As a result of this research, it could be said that the science-play activity can improve the student's science process skills and the science related attitude, and the science-play program should be further developed and applied to make easy and effective science classes.
