The purpose of this study was to investigate eighth graders' scientific method of inquiry used in their reports. We developed a framework, 'Analysis of Scientific Methods and Information Sources', with a perspective of the Nature of Science to analyze students' planning method, data analysis, and information sources. We then compared results with levels of questions to find out whether they affected students' 'Scientific Method'. In addition, we analyzed students' responses of the survey questionnaire, e.g.. how they liked Scientific Method. Results are as follows: First, 'planning method' consisted of 'consultant' and 'activities'. The 'activities' were 'experiment', 'correlational study', and 'observation' Students planned by utilizing 'consultant' more than the other. In case of planning 'activities'. most of them were 'experiment' Second, 'data analysis' consisted of 'summary', 'table', 'chart', 'graph' and so on. Students analyzed their data by using 'summary' frequently. The types of 'summary' were divided into 'simple summary' and 'relational statement' Third, 'information sources' consisted of 'computer', 'library'. and 'professional consultant' Most of the students gathered information from 'computer' Fourth, the types of 'planning method' and 'summary' were affected by the levels of questions. Fifth, some of the students reported their difficulty in 'planning method' because the collected information was less reliable, lacking, and having difficult technical terms.

This descriptive research investigates the knowledge of and attitude toward HIV/AIDS among individuals in their 20s to 40s. This study also analyzes the results of the 2011 and 2013 community health surveys to identify the factors influencing their knowledge and attitude. The study subjects were 20 to 49 years old, and the final analysis included 182,315 subjects. The collected data were analyzed through t-tests, ANOVA, correlational analysis, and multiple regression analysis. The survey results showed a high level of knowledge of HIV/AIDS, with 69.4% correct answers. Most individuals lacked knowledge regarding routes of infection, and those in their 20s had the lowest percentage of correct answers. As for attitude toward HIV/AIDS, 44.3% showed a negative attitude. The scores for knowledge and attitude toward HIV/AIDS were higher among males, unmarried individuals, individuals with a higher income, individuals with a higher level of education, individuals working in agriculture, forestry, or fishery, managers, professions that were not homemakers/unemployed, and professional soldiers. A positive correlation (r=0.27, p<0.001) was observed between knowledge and attitude. The factors influencing AIDS knowledge and attitude were gender, marital status, income level, occupation, and education level. This study confirmed that there is a difference by age group. As such, educational programs customized by age and other characteristics are expected to be more effective in enhancing knowledge and in developing a more positive attitude towards HIV/AIDS.

In this study, we examined the effects of video game play on a variety of areas of mental well-being, such as aggressive behavior, aggressive cognition, prosocial behavior, prosocial attitude, antisocial behavior, antisocial attitude, positive affect, and negative affect. We conducted a multivariate meta-analysis on 22 studies (k= 54, N = 8,031) published between January 2008 and October 2019. The results of the meta-analysis indicate that exposure to violent video games significantly increased aggressive cognition and negative affect only in true experimental studies, but their influences were small. Furthermore, the exposure to violent video games did not increase aggressive behavior and negative affect across all the research designs (true experimental, quasi-experimental, and correlational). Moderator analyses revealed that the effects of exposure to violent video games were much larger for younger adults than for children and greater in male-biased studies than in gender-balanced ones. Additionally, studies using better methodologies were less likely to produce negative effects. These findings suggest that the effects of exposure to violent video games on aggression were not as severe as popular opinion holds, and the effects were heavily modulated by the age and gender ratio of the participants, and methodological quality of the studies.

This study was designed to enhance preservice teachers' self-efficacy beliefs and pedagogical content knowledge (PCK) through scientific investigations based on current science education reforms. To do so, a science methods course was revised to include modeling effective scientific inquiry practices as well as designing and teaching scientific investigations in the K-5 practicum classrooms (Revised Science Methods Course). This study assessed the following research questions: (1) What level of PCK do preservice teachers have before and after the completion of RSMC; (2) To what extent do participants change their self-efficacy in science teaching after completing RSMC; and (3) Is there any correlation between participants' changes in self-efficacy and the level of PCK. Participants were 76 preservice teachers enrolled in a science methods course offered at a medium-sized university in the midwestern United States. This study employed the STEBI-B survey and the PCK rubric. There result of the study indicated that there was significant increase in Personal Science Teaching Efficacy (PSTE) of the participant preservice teachers after the completion of the course. Based on the PCK rubric analysis, there was a significant increase in mean scores of the post-RSMC lesson compared to those of the pre-RSMC lesson. The correlational analysis of participants showed a positive correlation between changes in self-efficacy and the level of PCK. Thus, it may be concluded that the reform-based science methods course had a positive impact on participants' self-efficacy in science teaching through correcting misconceptions, developing higher level of PCK, and modeling scientific investigation in their practicum schools.

Objectives: Cognitive-behavioral scientists have long been interested in how a pain patient's cognition such as locus of control relates to coping and adjustment. The present study examined the relationship of locus of control orientation to pain coping strategies, psychological distress and perceived pain intensity of patients with pain. Methods : Subjects were 96 patients with pain who visited pain clinic. All patients were administered the Multidimensional Health Locus of Control Scales, the Minnesota Multiphasic Personality Inventory, the Coping Strategies Questionnaire, and rating for perceived pain intensity, distress, and duration. Results : Correlational analysis revealed that patients who viewed outcomes as controlled by internality tended to have better ability to control and decrease pain. Also they tended to be less depressed and anxious. Regression analysis indicated that patients having a internal locus of control were more likely to use coping self-statement and reinterpreting pain sensation. Powerful others and chance locus of control orientation were predicted reliance on catastrophizing. Conclusion : The clinical implication of the present study is that cognitive factors of patients with pain such as locus of control influence emotional distress and coping. this study show that these factors should be applied to cognitive behavioral therapeutic intervention.

This study was conducted in order to test a model in relation to active coping strategy, academic resilience, and subjective happiness in college students. Also, sought to test the mediating effects of academic resilience in the relationship between active coping strategy and subjective happiness. Data was collected through a self-report questionnaire which was administered to 400 college students. Correlational analysis and structure equation modeling analysis were conducted to test the research models. The results were as follows: First, as the level of active coping strategy increased, the level of academic resilience and subjective happiness increased. Second, as the level of academic resilience increased, the level of subjective happiness increased. Third, the model with active coping strategy as a prophetic variable, academic resilience as a mediating variable, and subjective happiness as a result variable showed a full mediating effect. Thus, although active coping strategy has no direct influence on subjective happiness, it has an indirect effect on subjective happiness by enhancing academic resilience. The results of this study are expected to provide basic data on research and education for the improvement of happiness in college students and to help them develop educational counseling and training programs for improving their happiness and adapting to college life.

The purpose of this study is to construct the evaluation model for the major science research facilities and equipments to enhance the competitiveness of the science and technology and also to test the reliability and validity of the model. To achieve the purposes, this study theoretically reviews the concept of the major science research facilities and equipments and their characteristics. Through a review of literature, this study draws 11 criteria for evaluating the priorities of the major science research facilities and equipments. These criteria are categorized as two dimensions - 'science & technology' and 'national policy'. The dimension of science & technology includes scientific importance, technological readiness, utilization rate, common utilization rate, and ability of management and operation. The national policy dimension contains degree of correspondence with national science development, imperativeness of national policy, science and technical effectiveness, economic and industrial effectiveness, responsiveness of research demand, and equity among the related institutions. The competitiveness of the science and technology consists of these two dimensions. The evaluation model is established on the framework of criteria. The 18 major science research facilities and equipments are selected through a series of Delphi. The survey of experts (BT, ET, IT, NT and ST) is also implemented to evaluate the 18 major science research facilities and equipments by 11 criteria. The overall results indicate that the reliability and validity of the model are good. The reliability tests show that the five indicators of science & technology and the six indicators of national policy have high internal consistencies. The confirmatory factor analyses reveal that the two constructs - 'science & technology' and 'national policy' - have high convergent and discriminant validity. The correlational analyses also show that the criteria-related validity between them is high. Furthermore, the results of higher order factor analysis indicate that the fit indices of the model are high and suggest a good fit to the data. Based on these findings, the policy implications of the model are discussed.
