This study is to investigate many kinds of conceptual models of social problem solving approach as well as decision making method, and then describes educational implications, especially for more effective method of teaching problem solving ability in order to reduce children' anti social behaviors and to be able to have their healthy and happy lives. Problem solving ability or decision making skills have been taken to goal of primary school curriculum, but is too cognitive or too centered to morality for student to get that kinds of skill or competency. As a result of new education method is developed on the basis of Socal Emotional Learning(SEL) as well as Emotional Intelligence which put on the importance on the role of emotion in the problem solving. This method have two distinctions. First, It has the background of culture specific views of emotion to be proper this method in our society. Second, It should be integrated into moral education as a part of school curriculum to establish secure and long term intervention.

Since Korea experienced a 'jobless growth' in 2003, creating jobs in the service sector has been considered as a top priority employment agenda. However, despite high employment outcomes in services, labor productivity remains stagnant in the service sector in recent years. A great deal of concern has been raised regarding newly created service jobs. Critics say low productivity in the service sector will harm the engine of economic growth in our country. This paper investigates the side of the demand for quality of labor, namely, the demand for skills as one of the main source of low productivity in the service sector. To analyze the changes of skills demand, this paper suggests the concept of job-based skills instead of worker-based skills and presents the way of constructing measures of job-based skills. By means of common factor analysis using job information in the Korean Dictionary of Occupational Titles, I extract 4 direct measures of job-based skills, such as cognitive skills, physical skills, fine skills, interactive skills. These skill measures are used to explore and to test how the skill structure changed in the service sector during 2002-2006. Empirical Results show that whereas the goods sector makes progress toward upskilling being represented by increased cognitive elements and softenization of tasks, the service sector, although high-educated workers increased, exhibits trends of deskilling in the sense of job-based skills during 2002-2006 in Korea. The trend of deskilling however does not seem a general aspect in the overall service sector. Rather, it seems a compound process that high-skilled jobs are created, but, on the other hand low-skilled jobs requiring physical labor are produced at the same time.

Background: The purpose of this study was to identify the influence of workers' perceived workload, accident experiences, supervisors' safety leadership, and an organization's safety climate on the cognitive and emotional risk perception. Methods: Six hundred and twenty employees in a variety of manufacturing organizations were asked to complete to a questionnaire. Among them, a total of 376 employees provided valid data for analysis. To test the hypothesis, correlation analysis and hierarchical regression analysis were used. Statistical analyses were conducted using IBM SPSS program, version 23. Results: The results indicated that workload and accident experiences have a positive influence and safety leadership and safety climate have a negative influence on the cognitive and emotional risk perception. Workload, safety leadership, and the safety climate influence perceived risk more than accident experience, especially for the emotional risk perception. Conclusion: These results indicated that multilevel factors (organization, group, and individual) play a critical role in predicting individual risk perceptions. Based on these results, therefore, to reduce risk perception related with unsafe behaviors and accidents, organizations need to conduct a variety of safety programs that enhance their safety climate beyond simple safety-related education and training. Simultaneously, it needs to seek ways to promote supervisors' safety leadership behaviors (e.g., site visits, feedback, safety communication, etc.). In addition, it is necessary to adjust work speed and amount and allocate task considering employees' skill and ability to reduce the workload for reducing risk perception.

Objectives: We evaluated the learning objectives of dental hygiene courses based on Bloom's learning objectives, and analyze the degree of match with the dental hygienist's job for each detailed subject. Methods: The 5th edition of 'Dental hygiene and learning objectives' was analyzed by subject based on Bloom's cognitive domain classification from March 10 to April. In addition, the degree of match between the contents of the secondary job analysis of the dental hygienist and the learning objectives for each detailed subject were analyzed. Results: The total number of dental hygiene learning objectives was 2,975 (2,762 theory, 52 practice). Among the cognitive domains, the comprehension domain was the most common (79.8%), and the skill domain was very low (4.9%). In the job for each detailed subject of dental hygiene, the most frequently performed was 'dental prophylaxis and practice' with 103 subjects. Conclusions: Overall, dental hygiene learning objectives are mostly theory-oriented, so it is necessary to expand and improve in the direction related to the jobs that clinical dental hygienists perform in the field. In addition, it is necessary to continuously develop timely learning goals, and prepare active strategies for developing high-quality items.

Due to recent enhance of safety law and regulations in construction sites, safety inspectors have been more required in construction sites. However, most of them are novice for safety inspection which have not enough experience and skill. Therefore, the novice safety inspector's performance on hazard recognition needs to be improved for effective safety management. The performance of safety inspection is influenced by the inspector's experience and background because the inspection is usually conducted by the inspector's eyes. Therefore, there is a difference in safety inspection performance between novice and experienced safety managers. This study aims to analyze the gap of risk perception between novice and experienced safety managers using quantitative visual data. For this objective, this study conducted eye tracking experiments for novice and experienced group to evaluate cognitive performance of safety risk factors. The results provides the level of safety awareness based on their experience in construction safety. The limitation of this study is a lack of the number of samples used in this study and did not consider the various characteristics of the participants. If these limitations are supplemented in future research, it can be used to develop safety education contents for novice safety managers.

Problem-solving ability is one of the most important learning outcomes for students to compete and accomplish in a knowledge-based society. It has been empirically proven that visualization plays a central role in problem-solving. The best performing problem-solver might have a strong visualization tendency. However, there is little research as to what factors of visualization tendency primarily related to problem-solving ability according to phases of problem-solving. The purpose of this study is to identify the relationship between visualization tendency and problem-solving ability, to determine which factors of visualization tendency influence problem-solving ability in each phase of problem-solving, and to examine different problem-solving ability from the perspective of the levels of visualization tendency. This study has found out that visualization tendency has a significant correlation with problem-solving ability. Especially, Generative Visualization and Spatial-Motor Visualization as sub-visualization tendency were more strongly related to each phase of problem-solving. It indicates that visualization tendency to generate and operate mental processing can be considered a major cognitive skill to improve problem-solving ability. Furthermore, students who have high visualization tendency also have significantly higher problem-solving ability than students with low visualization tendency. It shows that the levels of visualization tendency can predict variables related to students' problem-solving ability.

In this study, the 'extended science investigation' was conceptualized as a comprehensive science investigation contrasted with exercise of process and skill component and cookbook style experiment. The extended investigation tasks can be characterized with practical context. openness and continuity. The purpose of this study is to describe the change of students' cognitive engagement while they perform the extended science investigations and to explore how the characteristics of the extended investigation tasks affect the students' cognitive engagement. 128 7th graders attending coeducational school in Seoul were participated in this study. The questionnaire was implemented repeatedly to monitor students' cognitive engagement. And ten students were interviewed to explore the cause of the change of cognitive engagement. The result showed that there was no difference between directive traditional investigations in textbook and developed extended investigations in understanding of the content and whole process of investigations but participants' commitment was increased significantly in the extended science investigations. Especially the extent of students' understanding and commitment became higher in the second half than in the first half of the extended science investigations. The openness of the extended investigation tasks contributed on the increase of commitment. And the continuity of the tasks contributed on the increase of students' understanding in the second half of the extended science investigations.

This practice parameter for non-pharmacological treatment for attention-deficit hyperactivity disorder (ADHD) review the domestic and international literature on the psychosocial treatment of children and adolescents with ADHD. This parameter include the parental training & education, cognitive behavior therapy(group or individual), social skill training, family therapy, play therapy (individual psychotherapy) and non-traditional therapy (art therapy, herbal therapy et al). Among them, there is some proven evidence only in parental training & education and cognitive behavior therapy. So, this parameter describes some details only in the field of parental training & education and cognitive behavior therapy. The efficacy or effectiveness, especially, cost-effectiveness of specific psychosocial treatment method for ADHD cannot be fairly assessed due to the scarcity of controlled clinical data. Based on the clinical expert consensus and limited evidence, we cautiously suggest the practice recommendations about the non-pharmacological psychosocial treatment fur children and adolescents with ADHD.

Teaching-learning activities in a school class is influenced by the development of a information science in the 21 century. Recently, the instruction in a school class use a multimedia teaching-learning contents chiefly. A great number of teachers don't recognize a foundation of the effects on teaching-learning contents utilizing multimedia. In this paper, I propose to analyze and verify the foundation of effects on cognitive psychology of multimedia teaching-learning contents. The principal method of this study is to synthesize and analyze researches of scholars or literature study largely. In this paper, the foundations of effects on multimedia teaching-learning contents are following: the dual encoding of information process, the skill on direction and speed-regulation of learning, and the others educational strength. The theoretical conviction in multimedia teaching-learning contents is operated as the confidence of education contents & media utilized by teachers and learners, and is anticipated as the growth of the quantitative and qualitative learning activities.
