Purpose: The purpose of this study was to investigate and compare human papillomavirus (HPV) vaccination status associated with HPV health belief and knowledge between male and female highschool students. Methods: In the winter of 2012, 183 students responded to self-administered questionnaires, and t-test, ${\chi}^2$-test, and ANOVA were used for data analysis. Results: There were significant differences in the experiences of hearing about HPV vaccination, source of HPV information, experience of being vaccinated with HPV vaccination, reason for HPV unvaccination and vaccination intention by gender. The mean scores for health belief of HPV vaccination were 1.72 (total score: 4) in men and 2.31 in women. There were significant differences in HPV health belief (t=-5.14, p<.001). The mean scores for knowledge of HPV vaccination were 0.08 (total score: 1) in men and 0.12 in women, but there were no significant differences in HPV knowledge (t=-1.62, p=.108). There were positive associations between HPV health belief and knowledge in women (p=.02). Conclusion: This study showed different HPV vaccination status, health belief and knowledge in gender. The results indicate a need to consider levels of health belief and knowledge of HPV vaccination in target populations of highschool students when planning a HPV related education program.

This study examined the effects of the ARCS model for science education and found a way of improving ARCS while finding any weaknesses. More specific research questions were as follows: 1) Does the ARCS model enhance the learners' achivement in highschool Earth Science significantly?; 2) Does the ARCS model enhance the learners' motivation in highschool Earth Science significantly?; 3) What are the weaknesses of the prescriptions of the ARCS model for designing a lesson, if any?; 4) How can the weaknesses of the prescriptions of the ARCS modeI be overcome? In order to fulfill the purpose of this study, the two major research methodologies were implemented: pretest-posttest control group design and formarive research. This study was conducted in two distinct phases: 1) designing a set of instructions for 4 weeks with the principles of the ARCS model (to find the weaknesses of the ARCS model) and 2) teaching the instructions and checking the effectiveness of the ARCS model by pretest and posttest with control and experimental groups(to find weaknesses of the underlying theory of the ARCS). After the experiment, each group took an achievement test and an attitude test on the given instruction and gathered data were analyzed with t-tests. Also, from each four classes 7$\sim$8 students were randomly sampled and individually interviewed about the instructional effectiveness and their preference on the instructions. The results of this study are summarized as follows: Significant differences between the control group and experimental group are seen in three components; Attention, relevance, and satisfaction. No significant differences are seen in the attitude of confidence. The weakness of the prescriptions of the ARCS model, are insufficient of strategy for 'confidence'. For overcoming the weaknesses of the prescriptions of the ARCS model, developmental type research is needed.

In this study, we investigated the difference in the affective characteristics between science-gifted students and general students through the positive experiences about science (PES) index. We also explored ways to apply the characteristics of gifted classes suggeseted by the teachers of this study, which had a positive effect on science-gifted students, to general science classes. For this study, a PES survey was carried on middle school science-gifted students enrolled in the gifted education center in the central region and general middle school students in the same area who had no experience in gifted education. Based on the survey result, we conducted in-depth interviews with teachers, having teaching experience with both science-gifted and general students. The results revealed that science-gifted students showed a significantly higher PES index than general students in all five areas of PES. The area with the largest difference between the two groups was science-related self-concept and the smallest was science academic emotion. Teachers suggested ways to apply the characteristics of science-gifted classes to general science classes, such as organizing general science classes around inquiry activities, supporting class materials such as MBL or tablets, reconstructing the classes using materials reflecting students' needs, and changing the textbook content and narrative style, to induce students' interest and curiosity. Based on the study results, ways to enhance the PES through science classes for general students were proposed.

This purpose of this study was to survey sense of self-control, social support and daily stress in female highschool students and to identify variables influencing daily stress. Data were collected 164 female highschool students. Data were handled statistics using t-test, ANOVA, Scheffe's test, Pearson's correlation coefficient and Stepwise Regression Analysis. The mean score of sense of self-control was 20.47±3.86. There was statistically significant difference in sense of self-control on factor such as satisfaction of school life. The mean score of social support was 105.88±19.63. There were statistically significant difference in social support on variables such as satisfaction of school life, parental rearing attitudes. The mean score of daily stress was 58.96±17.33. There was statistically significant difference in daily stress on factors such as relationship with school fellow, satisfaction of school life and parental rearing attitudes. Daily stress was negatively correlated with sense of self-control and social support. Sense of self-control was positively correlated with social support. Factor influencing daily stress were social support, sense of self-control, which explained 45%. Further study with careful sampling will be needed to reduce the daily stress of highschool students.

The work function of Ag (silver) is too low (~4.3 eV) to be used as an electrode of T-OLED (Top Emission Organic Light Emitting Diode). To solve this weakness, researches used plasma-, UV-, or thermal treatment on Ag films in order to increase the work function (~5.0 eV). So, most of studies have focused only on the work function of various treated Ag films, but studies focusing on nanomechanical properties were very important to investigate the efficiency and life time of T-OLED etc. In this paper, we focused on the mechanical properties of the Ag and $AgO_x$ film. The Ag was deposited on a glass substrate with the thickness of 150 nm by using rf-magnetron sputter with the power was fixed at 100 W and working pressure was 3 mTorr. The deposited Ag film was UV treated by UV lamp for several minutes (0~9 min). We measured the sheet resistance and mechanical property of the deposited film. From the experimental result, there were some differences of the sheet resistance and surface hardness of Ag thin film between short time (0~3 min) and long time UV treatment. These result presumed that the induced stress was taken place by the surface oxidation after UV treatment.

The purpose of this study is to develop an inventory to classify task commitment types of science learning and to classify highschool students' task commitment types. Firstly, inventory questions were designed following the literature analysis on the task commitment components which involve self confidence, high goal setting, and focused attention. Prototype inventory underwent the content validity test, pilot test, and reliability test. Through these steps, final inventory was input to 462 high school students and underwent the factor analysis and cluster analysis. Factor analysis confirmed three components of task commitment as the three factors of inventory questions. In order to find how many clusters exist, factors of developed inventory became new variables. Each factor's factor mean was calculated and served as the new variable of the cluster analysis. Cluster analysis extracted five clusters as task commitment types. The 5 clusters were suggested by the agglomarative schedule and dendrogram gained from a hierarchical cluster analysis with the setting of the Ward algorithm and Squared Euclidean distance. Based on the factor mean score, traits of each cluster could be drawn out. Inventory developed by this study is expected to be used to identify student commitment types and assess the effectiveness of task commitment enhancement programs.

The purpose of this study is to investigate the difference and relations in science related attitudes and science achievement in highschool students. Investigated differences between science related attitudes and science achievement and evaluated variations within city type, gender, grade level group. 404 high school students in Korea were sampled by cluster sampling method. Two instruments were used in this study. The ABC inventory(affection. behavioral intention. cognition scale of attitude toward science) was developed by the researcher(Lee, 1996, 1997). And MSAS(modified scientific attitude scale) has modified previous one. The major results are as follows: 1. Highschool students' Attitude toward Science is 3.24, 5-rating summative Likert scales. It showed slightly positive and favorable. 2. Highschool students' Scientific Attitude is 3.37, 5-rating summative Likert scales. It showed slightly positive tendencies of scientific attitude. 3. Findings indicated that middle' small city's students scored higher in Attitude toward Science and Scientific Attitude than metropolitan students. 4. The relationship between Attitude Toward Science and Scientific Attitude is 0.5716. The relationship between Scientific Attitude and Science Achievement is weaker than the relationship Attitude Toward Science and Science Achievement. 5. The results of three-way ANOVA indicated that were significant group differences(p<.05) in Attitude toward Science and Scientific Attitude. 6. After adjustment for the covariate(Scientific Attitude's score), statistically significant main effects of all group were found on the Attitude toward Science(p>.05). But after adjustment for the covariate(Attitude toward Science's score), statistically no significant main effects of all group were found on the Scientific Attitude(p>.05).
