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.

The purpose of this study is to find out a model to explain the process of students' science-related career choice by identifying the causal relationships between science career choice and related factors. Important factors of science-related career choice were identified through factor analysis. 'Perception about career related to science', 'preference for science learning' and 'participation in science related activity' were three main factors of science-related career choice. A questionnaire was developed to know the factors of students' science-related career choice, and so as to make it possible to be analysed by structural equation modeling. The subject were 947 grade 6, 9, and 11 students in Seoul. Numbers of boys and girls in each grade was almost same. According to the structural equation modeling, 4 corrected models were obtained. In all 4 corrected models, 'perception about career related to science' had direct influence, and 'preference for science learning' and 'participation in science related activity' had indirect influence on science-related career choice. In the most fitting model. 'perception about career related to science' had an effect on science-related career choice with standardized total effect coefficient 1.03(direct effect 0.82, indirect effect 0.21). 'Preference for science learning', which influence 'participation in science related activity', had an effect on science-related career choice with standardized indirect effect coefficient 0.65. 'Participation in science related activity', which influence 'perception about career related to science'. had an effect on science-related career choice with standardized indirect effect coefficient 0.79. The implication to school science education is that it is most effective to raise the 'perception about career related to science' in order to make more students choose science related career. It is also effective to have more students participate in science related activity and enhance the preference for science learning. To explain the process of science related career choice more fully, it is necessary to build a more comprehensive model containing more factors influencing science-related career choice. It is necessary to test and complement the structural equation model by enlarging the subject to science high school students and science related college students.

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 was to investigate the changes of attitudes related to science of students in high school science club through modified the creative-experience activity model program. To begin with, using the creative-experience activity model program the programs adapted to the school practices have been developed through consultation of the teachers. The developed program was performed on students in the high school science club. Then we studied the changes of attitudes related to science of students through their outcomes of the activities and face-to-face talk. The change of attitudes related to science of students is positive, especially problem-solving, curiosity, a sense of responsibility, interests toward science, interests toward science related careers, and leisure interest in science. Interest for science as hobby were influenced by used tools like telescopes and experimental tools. Interest for science class were not effective to change to positive by creative experience activity. It seems to be due to creative experience activity were not connected with science class. The program to participate in the activities was more effective than to observe with visit for the change of the attitude related to science. Also, the programs with activities contained scientific knowledge were more effective.

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.

An effective strategy for obesity intervention should include demographic, health-related, and work-related factors that are most relevant to the target population. Factors most strongly associated with obesity may differ for groups of individuals across industries or age categories. The purpose of this study was to provide current knowledge about the possible association between psychosocial job stress and immune parameters in blood. We assessed obesity-related parameters as well as the natural killer cell activity (NKCA) in female workers. There was a significant difference in the obesity-related blood parameters, i.e. fasting blood sugar level, according to age (p<0.05). Moreover, it showed a significant difference in NK cell activity between the obese and non-obese factor groups (p<0.05). Pearson correlation analysis demonstrated that NKCA was closely correlated with obesity related factors. In the future, it would have to study the biological changes which increase the activity of the immune factors to the immunological response.
