Purpose: This study was to examine the effect of an obesity management program on the body weight, body-mass index, and physiological index of obese female high school students. Method: Students from one school were selected as the experimental group, and students from another school as a control group so the latter group wasn't exposed to the experiment. The experimental group and the control group were each organized with 20 students. The experimental group received 60 minutes of behavior modification once a week, for eight weeks. Result: The Body weight, and Body mass-Index of the experimental group significantly decreased after the obesity management program. Total-cholesterol, T-G, and LDL-C significantly decreased and HDL-C increased in the experimental group. Total-cholesterol, T-G, LDL-C and HDL-C between the experimental group and control group showed significant differences. Conclusion: These results indicate that the obesity management program had a great effect on decreasing the body weight and body-mass index of the female obese high school students, normalizing their physiological index. In conclusion, this program turned out to be one of the safest and most effective obesity-management methods that could be applied to female high school students.

As science programs emphasize an understanding of the nature of science, it is needed to assess students' views on a wide range of science-technology-society topics. The purpose of this study is to investigate the views of high school students about some selected topics of the epistemology of science. The selected topics include the meaning of science, scientific assumptions, values in science, conceptual inventions in science, scientific method, consensus making in science, and characteristics of the knowledge produced in science. Identified preconceptions in the study are as follows: Science was seen as improving the world(20%), and technology was defined as the application of science(35%). Almost half of the sample(49%) subscribed to a view consistent with a creationist posture and large group of students(46%) expressed a purely ontological view. Only minority of the students(5%) discounted the role played by private science values, but one half of the sample denied the fact that gender-related values can influence the knowledge that scientist construct(53%). Only a small potion of the sample(5%) held a view contrasting to contemporary epistemology of science, but the majority(67%) expressed a simplistic hierarchical relationship in which hypotheses become theories and theories become laws. One third of the students(33%) held a preconception that the scientific method composed of questioning, hypothesizing, collecting data, and concluding. Students did not appreciate the role of consensus making in science(33%). An out-dated epistemic perspective describes the progress of science as simply an accumulation of knowledge(4%). In general, it was concluded that most high school students did not hold efficient understanding on the nature of science. It can be said that no adequate and consistent instruction took place to provide students with an authentic view of the nature of science.

As other major, students have difficulties to be successfully adapted to computer science major without some interest and skill to computer programming. In this paper, we try to find successful factors for computer science major freshmen students to computer programming. The factors we focused are programming experience before college entrance, taking liberal arts/natural science courses at high school, application motivations to computer major, existence of mentors, satisfaction to his/her computer department, student's holland job aptitude code. After analysis, taking liberal arts/natural science courses at high school, satisfaction to computer department, some holland job aptitude code are significant to their successful adaptation to computer major. Also, we found the holland job apptitude code is closely related to student's satisfaction to their major for engineering students including computer science students. Our analysis results will be a suggestion for designing computer science education program with students who enters college without some aptitude or preparation to his major.

The purpose of the study was to investigate the perceptions and opinions of culinary art high school and undergraduate students on the curriculum for Korean culinary arts education. The results of the research were as follows. High school students were found to be more satisfied regarding their culinary arts curriculum than college and university students (p<0.001). In addition, high school students gave a significantly higher score for the 'need for Korean culinary arts major' than college and university students' (p<0.001). University students placed more emphasis on the current policies and business projects of the government for globalization of Korean cuisine as compared to high school and college students (p<0.001). A high percentage of respondents perceived Korean cuisine to be 'old fashioned(44.6%), followed by 'difficulty in finding a good job(40.1%)'. Forty five% of the students responded that the important factor for Korean culinary arts education was the 'curriculum'. More than half of the students perceived 'ability to adapt traditional cuisine style to foreigners and modern customers' as a very important area. In terms of areas required to be included in Korean culinary arts curriculum, ‘basic cooking skills(4.49)' received the highest perceived need score, followed by 'languages(4.46)', 'traditional Korean food(4.33)' and ‘Korean food culture(4.21)'. The findings of the study can be used to develop a curriculum for Korean culinary arts major.

The purpose of this study is to examine the concept of Greenhouse Effect as understood by middle school high school university students using a closed-form questionnaire. Based on results of the questionnaire which was administered to 619, the extent to which alternative concepts were held was quantified and compared the difference of various group based on grade level. gender, text and major. Also, subjects were divided into two groups, one is middle school students and the other is high school university students and common themes within conceptual framework of each group were identified by factor analysis. The result showed that students confused Greenhouse Effect with ozone layer depletion in stratosphere and linked familiar contamination around everyday life. acid rain. radioactive contamination, nuclear arsenal to Greenhouse Effect. These trends were more appreciable in female than male, biology major than any other major and text did not make any significant difference. In addition, the result of factor analysis showed that two groups linked familiar contamination around everyday life to Greenhouse Effect and high school university students understand the consequences of an increase in the Greenhouse Effect more systematically than middle school student, perceived the relation between the origin of an increase in the Greenhouse Effect and human activity but confused Greenhouse Effect with ozone layer depletion in stratosphere.

This study investigated whether there was a difference between general teaching efficacy and science teaching efficacy of preservice elementary teachers. And, the difference was also examined in the area of several variables of the preservice teachers, such as gender, the university majors, the high school majors, and grades. The results showed that a significant difference was not found between general teaching efficacy and science teaching efficacy. Teacher variables were found as the major factors to explain the difference. In case of male students who are majoring in science/math at university, and the students who majored in science/math at high school, science teaching efficacy was higher than general teaching efficacy. Whereas, in case of female students and nonscience majors at university and high school, science teaching efficacy was lower than their general teaching efficacy. Educational implications for preservice elementary teachers were discussed.
