Analysis of the data concerning 525 middle and high school students showed that positive affect correlated positively with cognitive reappraisal strategy and with self-control but correlated negatively with expressive suppression strategy. Negative affect correlated positively with expressive suppression strategy and negatively with self-control. The group of higher positive and higher negative affect was higher than the group of lower positive and lower negative affect in cognitive reappraisal strategy. The group of higher positive and higher negative affect was higher than the group of higher positive and lower negative affect in expressive suppression strategy. The group of higher positive and lower negative affect was higher than the group of higher positive and higher negative affect in self-control.

The purpose of this study is to clarify variables dichotomizing adolescents into online game addiction-latency group and non-addiction group. Based on ecologic theory, individual system(self-esteem, self-control, depression, stress-coping strategy), family system(parental support), and social system(teachers' support and peer-group support) were suggest for variables affecting online game addiction of adolescents. 612 adolescents were tested for game addiction, self-esteem, self-control, depression, stress-coping strategy, and social supports from parents, teachers, and peer group. Independent t-tests showed between-group differences in self-esteem, self-control, depression, aggressive, and negative-avoiding stress-coping strategies, parental support, and peer-group support. Binary logistic regression analyses revealed that aggressive stress-coping strategy of social system and peer-group support of social system had significant influences on the division of the groups.

'Self-esteem' is defined as 'the lived status of one's individual competence and personal worthiness in dealing with the challenges of Life over Time'. High self-esteem is associated with self-confidence, effectively coping, well-being, and responsibility and it is essential for the responsible choice and determination of environments. The purposes of this study were to develop a strategy to enhance the self-esteem and to verify the effects. A new strategy, 'Cognitive Restructuring Strategy' was based on the characteristics of self-esteem and the key idea of this was to eliminate negative thoughts and to reinforce affirmative thoughts. We developed the statement to embody this strategy and applied to the experimental group. According to the results, self-esteem for the control group(155) did not changed but that for the experimental group(158) was significantly enhanced. Continuously, environmental learning instructions of 3 units were carried out on two groups. By applying the t-test, achievement-test scores for the experimental group per unit were significantly higher than those of the control group as regards the four respective goals of EE. Therefore this strategy and statement are helpful in enhancing self-esteem and it was found that 'self-esteem' is a influential factor to form environmental responsible behaviors(ERB).

Locus of Control of Reinforcement (LOCR)' is considered as one of the most important factors on responsible environmental behaviors(REB). It is defined as 'an individual's perception of his or her ability to bring about change through his or her behavior'. This psychological construct is divided up into two directions: the external locus and internal locus. The internal locus is important as a predictor of REB. Recently, 'The Environmental Action Internal Control Index: EAICI' has been developed and it is a valid and reliable instrument to measure the relationship of two variables. The purposes of this study were to develop a strategy to reinforce the internal locus or to converse external locus to internal locus. and to verify the effects by EAICI. A new strategy, 'Self Control Management Strategy' was based on the characteristics of internal locus and the key idea of this was to self-control and to manage the courses by themselves. EAICI scores of the control group was 99.83. All of them were internal and the LOCR of females was more internal than that of the males. This strategy was applied when the instructions were carried out on seven environmental issues by the experimental group. According to the results. the seven points of the EAICI were increased significantly. Therefore this strategy is helpful in reinforcing the internal locus or to converse external locus to the internal locus.

In this paper, we propose a method of cooperative control based on immune system in distributed autonomous robotic system(DARS). Immune system is living body's self-protection and self-maintenance system. Thus these features can be applied to decision making of optimal swarm behavior in dynamically changing environment. For the purpose of applying immune system to DARS, a robot is regarded as a B lymphocyte(B cell), each environmental condition as an antigen, and a behavior strategy as an antibody respectively. The executing process of proposed method is as follows. When the environmental condition changes, a robot selects an appropriate behavior strategy. And its behavior strategy is simulated and suppressed by other robot using communication. Finally much simulated strategy is adopted as a swarm behavior strategy. This control scheme is based on clonal selection and idiotopic network hypothesis. And it is used for decision making of optimal swarm strategy.

The purpose of this study is to find out the difference of sense of self-efficacy and stress encountering strategy of university students under the stress situation depending on the smart-phone user group (addiction group, general user group). For this purpose, the study issues are established as follows. First, it has analyzed what is the correlation of smart-phone addiction, sense of self-efficacy, and stress encountering strategy. Second, it has studied if there is any difference of sense of self-efficacy and stress encountering strategy for the smart-phone user group. In order to verify such study issues, For 1,670 university students in the Chungcheong area, smart-phone addiction scale, sense of self-efficacy scale, and stress encountering method scale were administered. Looking into the study result, first, as a result of the relativity analysis, it displayed the correlation of preference of test difficulty, self-control efficacy and important negative from the smart-phone addiction and sense of self-efficacy. In addition, all sub-variables of smart-phone addiction and avoidance orientation from the stress encountering strategy displayed the important positive correlation, and from the smart-phone addiction, the virtual world orientation and pursuit of social-support displayed the important negative correlations, and all sub-variables (interference with ordinary living, virtual world striving direction, withdrawal, resistance) of smart-phone addiction and problem solving-orientation displayed the negative correlation. Second, as a result of verification for the difference of the smart-phone addiction group and general use group following the sense of self-efficacy, the general use group is shown to have higher self-control efficacy sense than the addiction group. And third, as a result of verifying the difference of stress encountering following the smart-phone addiction group and general use group, the addiction group is shown to be lower than the general use group in terms of social support pursuit and problem solution orientation with the avoidance orientation shown to be higher. This type of result is expected to provide the base data when developing the smart-phone addiction preventive education program by finding out in details for the characteristics of smart-phone addiction group for university students.

In this paper, we propose a method of cooperative control(T-cell modeling) and selection of group behavior strategy(B-cell modeling) based on immune system in distributed autonomous robotic system(DARS). Immune system is living body's self-protection and self-maintenance system. Thus these features can be applied to decision making of optimal swarm behavior in dynamically changing environment. For the purpose of applying immune system to DARS, a robot is regarded as a B cell, each environmental condition as an antigen, a behavior strategy as an antibody and control parameter as a T-call respectively. The executing process of proposed method is as follows. When the environmental condition changes, a robot selects an appropriate behavior strategy. And its behavior strategy is stimulated and suppressed by other robot using communication. Finally much stimulated strategy is adopted as a swarm behavior strategy. This control scheme is based of clonal selection and idiotopic network hypothesis. And it is used for decision making of optimal swarm strategy. By T-cell modeling, adaptation ability of robot is enhanced in dynamic environments.

Self-assembled nanostructures of block copolymer thin films have gathered significant attention due to their potential applications as templates for nanofabrication. However the lack of a robust strategy to control the structure formation in thin film geometries has been considered a major obstacle for the practical application. In this presentation 'epitaxial self-assembly' will be introduced as a successful strategy to control the self-assembled nanostructure of block copolymer. Chemically patterned surfaces prepared by advanced lithographic techniques successfully registered nanodomains in block copolymer thin film without any single defect over an arbitrarily large area.

The purpose of this study was to investigate the effect of metacognitive strategy on conceptual acquisition ofvseasonal change and self-efficacy when it was applied to 6th grade elementary students. This study consists of 2 classes, 76 students in the 6th grade of elementary school, which were divided into the experimental group (38) and the control group (38). First, a pre-test was administrated to check students' levels of metacognitive self-regulation and self-efficacy prior to getting planned lessons and then an instruction program was developed based upon the metacognitive instruction model and students' conception. The control group was exposed to traditional methods mainly using the textbook and teacher's guide book. The experimental group employed a metacognitive learning strategy program and activities with metacognitive questionnaires. After the planned lessons, the students were tested with post-tests about the conception of seasonal change and self-efficacy. One month later the students were tested again with another test to determine the continuation effect. The results were as follows: First, the group that used metacognitive conceptual change instruction did better in forming and continuing to maintain the scientific seasonal change conceptions compared to the control group. Second, the high and intermediate group taught by metacognitive conceptual change instruction was higher in the level of self-regulation than the control group. However, it was not verified in the low group. Third, the group which used metacognitive conceptual change instruction showed a higher level of self-efficacy than the control group did.
