This study examined value-judgement and decision-making process of middle school students on three biotechnology related socioscientific issues (SSI) (i.e. designer baby, amniotic fluid test, and embryonic stem cell research). In particular, it focused on the level of consistency in their value application to the decisions. Twenty 8th grade students participated in the SSI program. The participants were asked to mark their positions on each issue before and after the debates. All classroom and sub-group debates were audio-recorded. The researcher conducted individual interviews with 10 students after the program. The results show three patterns emerging. First, five students applied their personal values in a consistent manner when making decisions on the three consecutive issues. Second, three students demonstrated incremental resoluteness in their value application as the sessions proceeded and had tendency to be oriented towards a specific value, more so towards the end of the program than the beginning. And third, four students gradually showed ambivalence in their decisions as they participate in the program. The results suggest that science teachers addressing SSI need to encourage students to be aware of their own values and to engage in internalized decision-making in light of those values. They also need to be aware of the possible challenges that students might feel in their decision-making process caused by the complexity of SSI.

The purpose of this study was to investigate the effects of black garlic supplementation and exercise on TBARS, HSP 70, and COX-2 expression after high-intensity exercise in rats. Twenty-four male Sprague-Dawley rats (4 weeks) were used in this study. Experimental groups were a control group (A, n=6), black garlic supplementation group (B, n=6), exercise group (C, n=6), and black garlic supplementation with exercise group (D, n=6). High-intensity exercise was performed by treadmill running (every 10 min speed increased gradually; 15~24 m/min, $0^{\circ}$ grade) and 2.86 g/kg black garlic for 4 weeks. The findings of this study were as follows: TBARS levels were significantly lower in the D group compared to the other group and B and C groups were significantly lower in TBARS levels than in the A group. HSP 70 expression was lower in the B group compared to the other groups. COX-2 expression has showed a similar expression in all groups. Therefore, it is considered that black garlic intake and exercise may reduce oxidative stress.

This study analyzed the learning objectives in the 2007 revised 10th grade Home Economics textbooks of 6 different publishing companies and the achievement standards developed by Ministry of Education, Science and Technology(2009). Two experienced coders performed initial analysis based on the 'revision of Bloom's taxonomy of educational objectives' and had subsequent conferences to reach an agreement on different results between coders. For knowledge dimension, the results show that the major types of learning objectives in the "Future Family Life" unit are mainly consisted of factual knowledge and procedural knowledge, where as those of "Family Life Culture" unit are consisted of factual knowledge and conceptual knowledge. The achievement standards in both "Future Family Life" and "Family Life Culture" units are solely in a factual knowledge major type. The sub-type of knowledge dimension of both learning objectives and achievement standards fall into 'a specific facts and knowledge component'. For cognitive process dimension, the results show that the leaning objectives are focused on 'understand' and 'analyze'. Those of achievement standards are 'analyse' in the "Future Family Life" unit and 'understand' in the "Family Life Culture" units. From the result of this study, we can conclude that both learning objectives and achievement standards do not adapt any meta-cognitive knowledge, higher order thinking, and cognitive process.

A survey questionnaire was developed by researcher, which consisted of 28 scales. Both descriptive and inferential statistics were employed for data analysis. Major findings of this study were as follows: First, school-related adjustment level of technical high school students was average. In sub-variables of school-related adjustment, 'compliance with the rule' was the highest, and 'relation to teacher' was the lowest. Second, five related variables were found to be a significant relationship with school-related adjustment level of technical high school students. They were 'orientation for freshman', 'student's department hope', 'teacher activity for student learning improvement', 'teacher support for student school life', 'parent's interest about school life'. Third, after multiple regression analysis, the proportion of the variance in school-related adjustment of technical high school students was about 42.2%. School-related adjustment of technical high school students was most explained by 'teacher activity for student learning improvement'.

The purpose of this study was to improve the academic achievement at the public practical center of technical high school in Busan. For this study, 1 class(31 students) in the second grade at "B"technical high school were selected and these students were divided into two groups. One is the experiment group which blended learning was applied to and the other is control group which traditional lecture method was applied to. Each group was divided into three sub-groups by the level of learning ability. Non-randomized control-group pretest-posttest design was applied for this experiment planning. The subject of experiment was the unit of "3D Modeling and Making NC code" in the textbook of "Application of Automatic System" applied by the public practical center of technical high school in Busan. On-line contents were developed and applied to the blended learning to control group. In order to analyze the test result, t-test with a significance level of 0.05 was carried out using SPSS 10.0. The results of this study was summarized as follows; First, as a result of the post test performed on the experiment and the control group, there was a significant difference between two groups, that was, the blended learning was more effective than the traditional lecture method in improving academic achievement. Second, blended learning was more effective than the traditional lecture method in the group of high-leveled and middle-leveled, but was little effective on the low-leveled group. Third, blended learning was more effective than the traditional lecture method in the functional domain, but was little effective in the cognitive domain and psychomotor domain.

This study was designed to identify the Attitude toward Engineering and Teacher Efficacy of pre-service teachers of engineering department, evaluate the validity of the difference and inquire into correlation between the Attitude toward Engineering and Teacher Efficacy. The study results are as follows. First, the Attitude toward Engineering of pre-service teachers of engineering department turned out to be 2.94, which is below average(3.00), and a bit lower figure than that of Teacher Efficacy(M=3.34). Second, there was no significant difference between the Attitude toward Engineering and Teacher Efficacy in a gender factor. In case of a major factor and grade variables, there was significant difference between Attitude toward Engineering and teaching efficacy of Teacher Efficacy. Third, as a result of analysis on the correlation between Attitude toward Engineering and Teacher Efficacy, it turned out that there was significant difference between in sub-area a few, which leads to conclusion that the attitude toward engineering and Teacher Efficacy will be gradually improved if educational institutes training pre-service teachers of engineering department operate teacher education courses considering major characteristics and learners' levels and give successful guidance to pre-service teachers. In addition, since the gender factor didn't make any significant difference between the attitude toward engineering and Teacher Efficacy, there is no need to develop and operate separate educational programs only for female or male pre-service teachers.

This study analyzes how the satisfaction of nursing students with their chosen major affected the outcome of their future engagement in the major. The survey included 127 nursing students at two nursing colleges, each located in Busan and Gyeongsangbuk-do, and results were analyzed using SPSS 22.0. Our results indicate that scores achieved for level of satisfaction in the major and engagement in the major were both higher than the mid value on a 5 point Likert Scale, being 3.91 and 3.61, respectively. Moreover, satisfaction with school life resulted in good health of the student. The student was self-motivated when applying to enter the school when level of satisfaction and engagement in the major was high. Engagement in the major was also predicted to be affected by other factors (accounting for 26%), in the following order: being satisfied with school life, self-motivated when applying to the school, and having a high average grade. Based on the results of analysis obtained by adding sub-variables pertaining to major satisfaction, 65.4% factors predicted to have an effect were general satisfaction as well curricular and relational satisfaction.
