This study was aimed to compare and investigate the difference of academic self-concept and social self-concept between multicultural children and general children. The data were collected from a total of 285 multicultural children and 223 general children in elementary school, during three months from February 20, 2014 to May 20, 2014. Collected data were analyzed using t-test, Pearson correlation coefficients, and enter multiple regression with the SPSS 23.0 program. Multicultural children showed lower scores in academic and social self-concept, parents attachment, social support, and school life adaptation than general children. And their mental health level was lower than the general children. The study results were that academic self-concept of multicultural children was influenced by learning activity (${\beta}$=.298), social maladaptation (${\beta}$=-.218), communication (${\beta}$=-.196), and confidence (${\beta}$=.167), which explained for 42.4% of academic self-concept. Social self-concept of multicultural children was influenced by support from friend (${\beta}$=.285), peer relation(${\beta}$=.187), social maladaptation (${\beta}$=-.172), and depression (${\beta}$=-.139). which explained for 46.3% of social self-concept. Since the influence factors of academic and social self-concept of general children and multicultural children have a great power of explanation, they can be used for the intervention program enhancing self-concept for school aged children.

This Study was to examine whether high school students' autonomy support and beliefs of intelligence ability influence their self-regulated strategies. Of the 600 high school students surveyed from 3 high schools in two metropolitan cities, Korea, 478 completed and returned the questionnaires yielding a total response rate of 79.7%. Among the final sample consisted of 109 gifted students (22.8%), 190 high-achieving non-gifted students (39.7%), and low-achieving non-gifted students (37.4%). Measures of students' perceived autonomy support (i.e. from parents, teacher, peer), beliefs of intelligence ability (i.e. incremental, entity) and self-regulated strategies (i.e. managing environment and behavior, seeking and learning information, maladaptive regulatory behavior). Spearman's rho(${\rho}$) indicated that students' achieving level was positively associated with autonomy support (i.e. parents, teacher), beliefs of intelligence ability (i.e. incremental) and self-regulated strategies (i.e. managing environment and behavior, seeking and learning information). However, students' achieving level was negatively associated with beliefs of intelligence ability (i.e. entity) and self-regulated strategies (i.e. maladaptive regulatory behavior). Hierarchical multiple regression analyses showed that students' perceived autonomy support (i.e. from teacher) and beliefs of intelligence ability (i.e. incremental) were the crucial contributors for enhancing students' self-regulated strategies. Results are discussed in relation to theoretical implications and school settings.

Nano-saftey has become an emerging issue recently, because of the broad use of nanomaterials in nano-industries and commercial areas. For a sustainable development in the nano-industry, active studies on nano-safety should be executed, especially on the potential risks in engineered nanomaterials (ENMs). Although acute and chronic assessments of nanomaterials have been extensively studied in many studies, multigenerational studies are very scarce. Overall, multigenerational studies have progressed as two different trends, studying post-generational effects or trans-generation effects. This study intended to suggest further nano-safety studies based on the trends and limitations of current ones. Through a comparative analysis, we investigated peer-reviewed multigenerational studies that used nanomaterials. Thirteen studies on post-generation effects confirmed generational nano-toxicity via several bioassays, such as mortality, fertility, and behavioral assays. Seven studies on trans-generation effects demonstrated nanomaterial pathways to next generations, using imaging techniques. Until now, mechanisms for post-generational nano-toxicity has been rarely proposed. Thus, we propose that complementary studies on such mechanisms are imperative for future studies.

This study researched the meaning of the outdoor play spaces used by young children, as perceived by them and their teachers. For this purpose, indirect observation, nonformal interviews during the activity of young children and in-depth interviews with teachers were conducted in 3 kindergartens and 1 day care center which operate various programs. As a result, outdoor play spaces were recognized as a psychological space, expanded space and sequential space for the relationships of young children. Meanwhile, early childhood teachers perceived them as a functional space, expanded space and restricted space of the children's daily lives. It was recognized that outdoor play spaces provided the children with good and unstructured environments to reorganize their own daily pattern through expanded play and the chance to naturally form peer relationships. This suggests that the space configuration which is most suitable for child centered development is one that is formed within and by their daily lives, rather than the standardized configuration of outdoor play spaces.

The current study examined the relationships between the adolescent's conflict resolution style and Big-Five personality factors, self-monitoring and self-esteem. Firstly, results showed that adolescent's big-five personality model affects their conflict resolution styles with their friends and peer group. In detail, the higher the neuroticism was, the stronger became the attack and avoidance strategies. The higher the extraversion was, the higher became the collaborative strategy and the lower became the attack and avoidance strategies. The higher the agreeableness was, the higher became the collaborative strategy and the lower became the attack strategy. The higher the conscientiousness was, the higher became the collaborative strategy and the lower became the avoidance strategy. The higher the openness to experience was, the higher became the collaborative strategy and the lower became the avoidance strategy. The higher the self-esteem was, the higher became the collaborative strategy and the lower became the avoidance and attack strategies. The higher the self-monitoring was, the higher became the collaborative strategy and the lower became the avoidance strategy. Secondly, the big-five personality factors also affected the adolescent's conflict resolution styles. The extraversion, conscientiousness, and agreeableness positively affected the collaborative strategy. The neuroticism was positively related with the attack strategy, whereas agreeableness was negatively affected the attack strategy. The neuroticism and agreeableness were positively related with the avoidance strategy, whereas the extraversion was negatively affected the avoidance strategy. Limitations and suggestions for future study were discussed thereafter.

Many biologists and various educational associations define evolution as a unifying theme as well as a central idea in biology. In this study, teacher education programs were developed as 18-hour courses on understanding the unified role and significance of evolution in biology, and their effectiveness was tested. As factors for the program content, enhancement of the acceptance of evolution, reinforcement of the conception of evolutionary theory, and recognizing and practicing evolution as the unifying nature of evolution were considered. Hands-on activities, self- and peer-evaluation, and projects based on the small teams including frequent questioning and feedback by instructors were considered methodological factors. Six in-service biology teachers and seven pre-service teachers took part in the programs of the graduate school of H university to testing their effectiveness. They were effective in improving the acceptance of evolution, the understanding of evolutionary mechanism, the perception on the unified role of evolution. The programs also induced a positive change in self-evaluation for knowledge of evolution and perception on importance of evolution in biology. Subsequent studies on whether the changed perceptions of the teachers who participated in the programs reflect on their biology classes in secondary schools after finishing the graduate program are required.

This study aims to examine the relationship between physical education class activity of youth, smartphone dependence and school life adaptation. The data set of Korean Children and Youth Panel Survey(KCYPS) by National Youth Policy Institute was reanalyzed for this study. The subjects of this study were 2,351 second grade middle school students from 2011. The data were coded with the use of the statistics program on Windows, SPSS 23.0. To analyse the data, descriptive analysis, reliability analysis, one-way ANOVA and regression analysis were employed. The findings of this research are as follows. First, the difference between the activity hours of youth physical education classes and the reliance on smartphones is less dependent on smartphones as they participate enthusiastically in physical education classes. Second, the difference of physical education class activity time and school life adaptation among adolescents was more positive for school life adaptation as learning activity, peer relationship and teacher relationship were more active. third, the dependence of youth on smartphones has a positive effect on learning activities and school rules as the reliance on smartphones is low.

This paper describes the Model-Based Development(MBD) process behind the flight control software of a close-range unmanned aerial vehicle(KUS-9). An integrated development environment was created using a commercial tool(MATLAB $Simulink^{(R)}$), which was utilized to design models for linear/nonlinear simulation, flight control law, operational logic and HILS(Hardware In the Loop Simulation) system. Software requirements were validated through flight simulations and peer reviews during the design process, whereas the models were verified through the application of a DO-178B verification tool. The integrity of automatically generated C code was verified by using a separate S/W testing tool. The finished software product was embedded on two different types of hardware and real-time operating system(uC/OS-II, VxWorks) to perform HILS and flight tests. The key findings of this study are that MBD Technology enables the development of a reusable and an extensible software product and auto-code generation technology allows the production of a highly reliable flight control software under a compressed time schedule.

This study aims to look into the effects of ego-resilience and social support on school adjustment of dormitory high school students in the convergence age. For achieving this purpose, a survey with 358 students in an autonomous private high school situated in D area was conducted. For analysis of the collected data, regression analysis was carried out using SPSS WIN 20.0. As a result, it was found that ego-resilience positively affected school adjustment, and optimism, curiosity and emotional control, which are sub-factors of ego-resilience, positively affected it, too. Also, social support positively influenced school adjustment, and peer support and teacher support that are sub-factors of social support, positively influenced it, too. Therefore, it is considered that developing various programs and school culture for improving ego-resilience and providing social support to prevent a lot of problems caused by school maladjustment of high school students in the digital convergence era will positively influence individual students, schools, families and furthermore general sections of the society, and diverse interdisciplinary convergence studies on this will serve as the foundation for future longitudinal research.

The purpose of this study was to examine the impact of the self- perceived stress of high school students on their oral health care and the relationship between stress and oral health care. The subjects in this study were the students in four different high schools located in Chungcheongnam-do, on whom a self-administered survey was conducted. The answer sheets from 939 respondents were analyzed by PASW Statistics ver.18.0 for Windows. The girls were more stressed than the boys about their studies, appearance and material resource, and the sophomores felt more stress about their home and studies. The group whose academic achievement was good in the past semester had the lowest stress about home and material resource, and the group whose economic standard was higher were less stressed about appearance and material resource. As a result of comparing their oral health care by general characteristics, the groups who were sophomores and whose academic achievement was good in the past semester were most excellent in that regard, and the students whose economic standard was higher and whose average weekly allowances were larger took better care of their oral health. Concerning the influential factors for oral health care, stress about peer relationship was positively related, and stress about material resource was negatively related. Given the findings of the study, the development of oral health care programs that include how to relieve stress is required, and more intensive education is necessary as well. Besides, education for school personnel in charge of student health management and the development of related manuals are both required.
