The objectives of this research is to examine: 1) how the rates of adolescents' BMI change over time in terms of the state level; and 2) development difference in the state level of BMI in terms of children's obesogenic behaviors from 1999 to 2011. Data were drawn from the 1999-2011 Youth Risk Behavior Survey in the United States (N=260, 293, grades 9-12, and 27 states). Ordinary least squares regression and hierarchical linear modeling were utilized to capture a longitudinal time effect of school-aged adolescents' obesity rates across the states, controlling for demographics and nutrition- and physical activity-related behaviors. The state's level of children's BMI percentile was significantly associated with longitudinal time. Longitudinal time effect across the states appears to play an important factor associated with children's decrease of BMI percentile. Therefore the states' implementation of physical activity and nutritional policies seems to be effective for preventing and reducing childhood obesity during last decade. More attention should focus on enforcing the policy and overcoming current barriers in order to minimize children's obesogenic factor.

This study applied self-determination theory to investigate the relationships between volunteers' perception of supervisors' autonomy support, volunteering motivation, and persistence intentions among collegiate students. Collegiate volunteers(n=515) involved in volunteer activities completed measures of supervisors' autonomy support, 5 forms regulation, and persistence intentions. Bivariate correlations indicated that volunteer motivation demonstrated an ordered pattern of relationships, such that adjunct points along the regulatory continuum would be more positively associated with on another than distal points. Analyses using structural equation modeling revealed that supervisors' autonomy support was positively related to more autonomous motivation(intrinsic motivation and identified regulation), while was natively associated with amotivation. Amotivation was negatively related with persistence intentions, and more autonomous motivations(intrinsic and identified) predicted grater intentions to continue with volunteer activity for next 6 months. The findings are discussed in light of the self-determination theory.

This study was designed to analyze the types of concepts about earth science related to seasonal changes, so as to develop a generative learning model focused on dissolving cognitive conflicts between the aforementioned concepts through debates and using said debates to find out how effectively the model works. There are 100 types of earth science concepts concering seasonal changes, 66 of which are unscientific in nature, including misconceptions. Through a second field trial and a research and development (R&D) process, a test on these concepts was developed, consisting of 14 items. For the experimental group, a four-phase generative learning strategy that reflects the types of earth science concepts and cognitive conflicts between such concepts was developed through pre-analysis and discussion, respectively. On the other hand, a traditional teaching and teaming strategy was used for the control group. A meaningful statistic gap found between the two groups through a covariance analysis, the significance level of which was 0.05. This result may be interpreted to mean that the generative teaming strategy is a possible alternative for correcting misconceptions about scientific concepts of seasonal changes.

The aim of this study was to investigate the association between self-rated oral health, self-rated health, and quality of life (QOL) among older population from the 7th Korea National Health and Nutrition Examination Survey (KNHANES VII-1, 2016). Data of 1,866 older adults (Mean age 69.5 years) were analyzed with hierarchical logistic regression analyses with IBM SPSS 23.0. Over 87.7% of the subjects rated their oral health as fair or poor. Women and less educated participants more likely to report their perceived oral health as poor (p<.05). Older participants who rated their general health positively were more likely to rate their oral health as good (F=19.04, p<.001). Elders who had bad perceived health (OR: 2.86, 95% CI: 1.5~5.5), had carries in permanent teeth (OR: 2.68, 95% CI: 1.67~4.32) and anxiety or depression (OR: 1.45, 95% CI: 1.42~2.57) had negative oral health perception after controlling for covariates. In conclusion, perceived oral health and QOL were associated with each other in Korean older adults. Therefore, it is recommended to approach holistic strategy for improve health and quality of life in the elderly population.

The aim of the present study was to determine whether secondary traumatic stress and burnout of CPS workers in Korea differ, being significantly affected by different variables of each own. A two-way MANCOVA was conducted to determine the effect of trauma exposure and work-condition satisfaction on secondary traumatic stress(intrusion and avoidance) and burnout(emotional deprivation, depersonalization, personal achievement) while controlling for gender, age, and personal trauma history. Exposure to clients' traumatic material did not affect secondary traumatic stress and burnout either. Rather, it was found that both of secondary traumatic stress and burnout was significantly affected by the same independent variables(level of exposure to being threatened by violent abusers of victims and the level of workers' satisfaction of work conditions in workplace). Therefore, it was difficult to address that secondary traumatic stress and burnout have a completely different construct.

Objectives : The purpose of this study was to examine whether the MMPI-2-RF serves as a useful tool to differentiate between the subtypes of high risk of suicide among psychiatric outpatients. Methods : Patients were recruited from the department of psychiatry of university hospital. Participants were diagnosed using DSM-5 criteria by board certified psychiatrists. Their medical records were reviewed retrospectively. And participants were put into 4 groups (Suicide ideation, Suicide attempt, Non-suicidal self-injury, and general psychiatric diagnosis as a control group). For statistical comparison, the MANCOVA with gender as a covariate was used. Results : The results indicated that as previous research with non-clinical sample suggested, psychiatric outpatients with high suicide risk also have significantly higher Emotional/Internalizing Dysfunction, Helplessness/Hopelessness, Suicidal/Death Ideation, Demoralization, Cognitive complaints, Cynicism, Dysfunctional negative thoughts than general psychiatric patients group. But group differences within the high suicide risk patients have not been observed. However, suicide attempt group and NSSI group has higher Behavioral/Externalizing Dysfunction, RC4, AGG than general psychiatric patients group. But there was no difference between suicidal idea group and general psychiatric patients group. Conclusions : There was no group difference observed between all three subtypes, which mean the MMPI2-RF may not be the useful diagnostic tool to navigate high suicide risk subtypes. Even though there was no difference observed in the suicide ideation group, suicide attempt group and NSSI group have higher aggression and externalization. So those indexes could serve as a useful marker to investigate riskiness of suicide related symptoms.

In this study, the instructional influences of the conceptual change model based on the cognitive conflict and the conceptual change model emphasizing the social consensus were investigated. The subjects were 109 7th-graders in a boys' middle school in Seoul, and were taught about the changes of states, density, and dissolution for 8 class periods. The hypotheses provided in the instructions were constructed from the results of a pilot test. Prior to the instructions, three tests regarding the perceptions of discussion, the attitudes toward science instructions, and the perceptions of participation were administered. Two types of the conceptual change instructions and the traditional instruction were used in the treatment groups and the control group, respectively. After the instructions, the students' achievement, the conceptions, the perceptions of discussion, the attitudes toward science instructions, and the perceptions of participation were investigated. ANCOVA results revealed that the scores of the treatment groups were significantly higher than those of the control group in the achievement test. Although the score of the treatment group using the conceptual change model emphasizing social consensus were higher than those of other groups in the conceptions test, the differences were not statistically significant. The perceptions of discussion were significantly more positive in the treatment group using the conceptual change model emphasizing social consensus than in the control group. However, there were no significant differences in the scores of the attitudes toward science class and the perceptions of participation among the three groups. Educational implications are discussed.

This study investigated the impact of student-centered instructions on students' academic achievement in science and on their attitudes toward science. Participants included 208 middle school students. The pre- and post-test control group design was employed. The control group was designed to have traditional instructions while experimental group 1 was applied both student-centered instructions and traditional instructions, and experimental group 2 was applied student-centered instructions only. The chaper of "Stimulus and Response" was selected for this study, and students were treated for 15 hours. Data were analysed using ANOVA. Results indicated that student-centered instruction had a significant effect on students' academic achievement(p<.01). The improvement of achievement through student-centered lesson is neither depending on genders nor previous academic achievement levels. Student-centered instruction also had a significant effect on students' attitudes toward science(p< .01). Only half of the class if a student-centered lessons and improve attitudes toward science could be. The improvement of the attitudes toward science through student-centered instruction is not depending on genders. But, student-centered instruction was more effective on the average student and the lower level students than the upper level students.

As the necessity of humanistic education has recently been socially emphasized, aptitude and character test has been conducted in the stage of training instructors to focus on making them equipped with proper ability of humanistic education. Especially, considering characteristics of students in specialized high schools with stronger negative concept of ego along with higher proportion of students looking for job in early ages compared to regular high schools, instructors in specialized high schools need to pay more attention on humanistic education of students compared to those in regular high schools. Therefore, this study has developed social emotion learning (SEL) of preliminary teachers in specialized high schools and analyzed the influence of developed programs on characters in teaching positions of preliminary instructors in specialized high schools. In this study, ADDIE model has been used developing SEL programs, and developed programs were comprised of total six sessions. Social emotion learning has been performed on 27 preliminary teachers in experiment group, and regular academic education courses were given on 30 preliminary teachers in control group. At this time, as for class contents, 'self-recognition' has been dealt with in the first and second sessions followed by 'self-management' in the second and third sessions, 'adjustment in relationship' in the fourth session, 'responsible decision making' in the fifth session, and 'personal relationship' in the sixth session. Classes have been conducted for 90 minutes in average. Since intentional sampling method has been used in this study, difference of pre-scores between groups might influence on the difference on post-scores. Therefore, ANCOVA that adjusted the pre-scores to be consistent has been utilized. As a result, there was a significant difference on the post-scores in characters in teaching positions between experiment group and control group.
