This study investigated the elementary school students' perception of the "purpose of scientists' experiments" and discovered what roles teachers can take to provide guidance. The study subjects were 193 elementary school students (96 boys and 97 girls) in a school located in Gyeonggi-do. The responses were analyzed through categorization based on their gender, science test score at school, and understanding of the purposes of scientific experiments based on students' choice of science-related future careers. The results of this study were as follows. In relation to the purpose of science experiments, the elementary school students considered intrinsic values of doing experiments more valuable than their extrinsic values. Next, 34.2% of the students answered that scientists do science experiment 'to find a new fact' and 26.9% of the students answered 'to make life convenient.' The results showed that girls responded 'social usefulness' more frequently than boys. Considering the achievement levels, it was found that high level students replied 'to make life convenient' more frequently than middle and low level students on why scientists do science experiments. Students who want to have a science-related career had varied ideas about it.

The purpose of this study is to develop the questionnaire on pre-service elementary teachers' recognition of self-understanding and change capacity for science education and to investigate their recognitions with it. At the beginning of the study, we made a tool to investigate the self-understanding and change capacity of pre-service elementary teachers through literature review and discussions. The former half of the questionnaire was related to self-understanding with factors such as 'self-concept clarity,' 'career identity' and 'self-efficacy:' 'self-understanding as a pre-service elementary teacher' (12 items) and 'self-understanding as a pre-service elementary science teacher' (12 items). Its latter half was about the change capacity with factors such as 'change sensitivity,' 'goal consciousness,' 'collaboration,' 'reflection,' and 'mastery.' It consisted of three parts: 'general change capacity,' 'change capacity as a pre-service elementary teacher' and 'change capacity as a pre-service elementary science teacher' with 17 items, respectively. With this tool, we surveyed 153 pre-service elementary teachers. The results are as follows: First, pre-service elementary teachers have a positive recognition about self-understanding and change capacity, but the recognition of self-understanding and change capacity as pre-service elementary science teachers were relatively less positive. Second, factors of self-understanding and change capacity as pre-service elementary science teachers have a significant correlation with each other. Especially, there was a high correlation between 'self-efficacy' of self-understanding and 'goal consciousness' and 'mastery' of change capacity. Based on these results, some implications for self-understanding and change capacity related to science education were discussed.

The purpose of this study was to explore the meanings of science classes to elementary school teachers from a phenomenological perspective. Participants were twenty-eight elementary teachers who majored in elementary science education in a graduate school of education. The study revealed that meanings of science classes were not consistent but rather varied with what the teachers experienced. In their early career years, when the teachers were filled with enthusiasm, they devoted themselves to doing science-related school works as well as science lessons. But, the teachers were gradually concerned about good science teaching, and this concern became more severe as they realized the characteristics of science experiments and elementary school students. The teachers' concern did not actually develop into good science teaching practices because of such constraints as lots of school works, accidents in science labs, and household affairs. Despite these difficulties, the teachers revitalized their interest in science and resumed their effort for good science teaching. However, for "unfillable cups" to the elementary school teachers.

Purposes : The purpose of this study was to analyze factors that could affect health of radiological technologists, which is useful for health care and development of programs for health promotion. Methods : Subjects were 234 of radiological technologists who work in general hospitals. Some questionnaires were made about perceptions of health condition and promotional behavior of health for this study. The questionnaires of health perception were 20 items that consist of the present condition of health, health concern and sensitivity. The reliability was sufficient(Cronbach's $\alpha=0.79$). The other questionnaires about health promotion behavior were 47 items that consist of self-realization, health responsibility, exercise, nutrition, personal relationships, and stress management. The results turned out to bewas sufficient (Cronbach's $\alpha=0.93$). Every data was treated statistically, comparison of average(t-test, ANOVA), correlation, and multiple regression. Results : Related factors to health promotion behavior were age, marriage, salary, class of one's position, career, employment, and religion, in general features. In health life habit, related factors were smoke and exercise. Results of health promotion behavior was 2.90 of mean score, 0.37 of standard deviation. Correlations between factors of health perception and health promotion behavior was positive(p<0.01). Health promotion behavior were affected by sensitivity, presents condition of health, exercise, smoke, career. Sensitivity was the most affectable variable, which means that promotional behavior score became higher and higher as the score of sensitivity and present condition were increased. In addition, persons who exercise regularly, had been smoked, and has higher career showed higher score of promotional behavior. Conclusion : Radiological technologists have to keep their health, trying not to infected by a disease. Most of all, no smoking and regular exercise are the most important thing to all of members.

The purpose of the study is to explore secondary science teachers' emotional display rules, types of emotional labor, science-specific emotional display rules and the episodes of emotional labor. For this purpose, the survey to measure emotional labor of science teachers (The Emotional Labor of Science Teaching Scale: TELSTS) was developed and the participants were 145 secondary science teachers in Korea. Results showed that first, secondary science teachers recognized the emotional display rules defined by their schools, especially, positive display rules. Second, secondary science teachers showed that they were carrying out emotional labor in order to keep their emotional display rules in check. The mean value of responses to deep acting was high. Also, there were statistically significant differences in emotional labor depending on whether they were full-time or part-time teachers and their teaching career. Third, as a result of analyzing the specificity of science teachers, it was mainly related to the objective and logical image of science, and experimental instruction. Seventy-four percent (74%) of responses were negative or neutral emotional display rules. Finally, implications for science education are discussed.

The purpose of this study was to identify factors that influenced elementary school teachers in choosing websites that support science teaching and learning. The participants of this study were four elementary school teachers. The data was collected through semi-constructed and in-depth interview. The results of the research are as follows: First, the individual factors that influenced participants to choose a website were teacher's thinking about appropriate science teaching and learning methods and teacher's lack of ability to prepare science lessons. Second, the surroundings factors were the image of the teachers using the website, the formation of consensus, belonging to the peer teachers, and students' preferences and interests. Third, participants chose a website where they could provide ideas for science lessons that are not available in textbooks and instructional materials for all subjects, and see stories and tips related to teaching career. In addition, the website was selected according to whether the developer of science instructional materials was a teacher, whether the materials uploaded on the website were up-to-date, and whether the teachers can learn by themselves to prepare for the science class. Fourth, participants considered the design and interactivity of the website and chose a website that is easy to search for information. Finally, we suggested the implications for building the websites that support science teaching and learning.

The purpose of this study is to empirically analyze the learning experiences of high school mathematics and science subjects of new students in science and engineering, and to provide basic data and respond to strengthen basic knowledge of science and engineering students in the future. The subjects of the survey were 481 freshmen in science and engineering at S University. First, as a result of analyzing the learning experiences of freshmen, the geometric subjects were significantly lower, which is the result of students' sensitive responses to transitional changes in the curriculum and SAT system after revision. In science, general elective subjects were higher than career elective subjects, and there was a deviation between science subjects, which is a result of reflecting the diversity and hierarchy of science subjects. Next, as a result of analyzing the difference in learning experience after revision compared to before the revision of the curriculum, the learning experience of Mathematics II increased significantly and the geometry decreased significantly. Both Chemistry I and II increased significantly compared to before the revision, and Earth Science I decreased significantly. This can be seen as a result of strategic choices based on obtaining grades in the CSAT and disadvantages in college entrance exams. As a result of the study, students' sensitive reactions to changes in the high school education environment were confirmed, basic mathematics and science-related courses were opened to alleviate variations in the academic ability due to elective courses, and countermeasures tailored to each university's situation.

Purpose: This study investigated the current status of post-traumatic stress and related factors among safety managers in Korea National Parks. Methods: The study subjects were 109 safety managers working in Korea National Parks. General characteristics, job-related characteristics, experience of traumatic events and post-traumatic stress were collected by self-reported questionnaires through the mail. The associated factors with post-traumatic stress was analyzed by t-test, ANOVA and multiple linear regression. Results: Overall score of post-traumatic stress was $10.32{\pm}11.37$ and 12.8% was the high-risk group of post-traumatic stress disorder. In simple analysis, score of post-traumatic stress was associated with drinking frequency, disease history, duration of career, delay of rescue, provided the break, rest space and the number of experiences of traumatic events. Finally, the score of post-traumatic stress was significantly higher in subjects who experienced 3 (B=9.141, SE=3.538) or more than 4 (B=11.367, SE=3.063) traumatic events compared to subjects without experience of traumatic event. Conclusion: The score of post-traumatic stress was $10.32{\pm}11.37$ and 12.8% was the high-risk group among safety managers in Korea National Parks. Post-traumatic stress was associated with the experience of traumatic events. Management of safety managers after mobilization or experience of traumatic events will be helpful to decrease of post-traumatic stress.

The purpose of this study is to investigate the status of admission and employment in fisheries high schools (FHS) and to consider ways to revitalize FHS through substantialization. The recruitment rate of new students in FHS decreased from 97.4% in 2016 to 83.2% in 2020. The aging training ship that FHS needs to improve most urgently is being jointly used by FHS across the country, and the construction of a joint training ship managed by the Korea Institute of Maritime and Fisheries Technology is being promoted. The average employment rate for FHS by year was 40.2-59.4%, and the fisheries-related employment rate was low at 31.0-38.9%. On the other hand, the acquisition rate of certificate of competence was 37.5-52.0%, and the rate of employment on board of those who obtained the certificate of competence was 42.9-59.8%. In order to secure new students and improve the recruitment rate, we operate experiential classrooms that reflect the characteristics of training ships and departments and conduct public relations activities using sns, publicity video ucc, YouTube, etc. It will be necessary to expand opportunities for fisheries-related vocational experience through active career exploration and elective courses in the FHS credit system. Finally, it is judged that fisheries related government agencies, industries and local governments need to improve their awareness of FHS and plan to support fisheries manpower nurturing in order to attempt the vitalization of FHS.
