In this paper a self-organizing fuzzy system with rule pruning is proposed. A conventional self-organizing fuzzy system having only rule generation has a drawback in generating many slightly different rules from the existing rules which results in increased computation time and slowly learning. The proposed self-organizing fuzzy system generates fuzzy rules based on input-output data and prunes redundant rules which are caused by parameter training. The proposed system has a simple structure but performs almost equivalent function to the conventional self-organizing fuzzy system. Also, this system has better learning speed than the conventional system. Simulation results on several numerical examples demonstrate the performance of the proposed system.

The main purpose of the study is to identify the key aspects of legislative support standards in the countries of the European Union in the field of building a system of local self-government. The European Union during the history of its existence has developed a set of standards on which the systems of local self-government of the European Union member states and applicants for this status are built. The complexity and at the same time the importance of legislative regulation of the functioning of this system is evidenced by the fact that the legislation and principles of international law used by the European Union in the field of local self-government are among the "youngest". This is due to the role played by local self-government in the development of a democratic political system, as well as the search for an optimal balance between centralization and decentralization. Thus, the main task of the study is to analyze the legislative support standards in the countries of the European Union in the field of building a system of local self-government. As a result of the study, current trends and prerequisites for the legislative support standards in the countries of the European Union in the field of building a system of local self-government were investigated.

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.

In the single-input and single-output system, the parameter of plant is scalar polynomial, but in the multiple input and multiple output, it accompanies, being matrix polynomial, the consideration of observable controlability index or problems non-commutation in matrix polynomial as well as degree, and it is more complex to deal with. Therefore, it is thought that a full research on the single-input and single-output system is not sufficient. This paper proposes that problems of minimum variance self-tuning regulator by using numerical calculation example of multivariable system and pole assignment self-tuning regulator.

For the compactness of regenerative combustion, self regenerative combustion and embedding regenerator inside furnace are proposed. The Self Regenerative burner system was developed to enhance thermal efficiency and Low Nox emission. In the twin regenerative system, two burner heads are generally used for preheating and exhausting combustion mode. But self regenerative burner system use only single nozzle body for regenerative combustion. Also two kind of regenerator, internal and external type, were designed to operate conveniently in both large and small furnace. According to test result, the self regenerative combustion system gives strong internal exhaust gas recirculation that reduce NOx emission significantly. NOx was measured as 50ppm(5% O2, 1290C furnace temperature). Also it is found that the fuel saving rate due to the self regenerative burner system reach to 30-40%. Thus it can be concluded that self regenerative mild combustion system appears to provide a reasonable regenerative burner for compactness and high performance as compared with conventional twin regenerative burner system. Also in the RT Application , compact twin regenerative burner was developed with the help of embedding regenerator inside furnace.

Purpose: Current study aimed at exploring the roles of system justification in the effects of consumers' self-identification with the threatened social in-group on the within-domain versus across-domain consumption. It focused on whether there are positive effects of both of the self-definition and the self-investment on the in-group system justification, and also explored whether the system justification, in turn, could make positive effects on the consumption. Research design, data and methodology: The self-identification was approached in view of self-definition and self-investment when the in-group was threatened by members of their out group. The empirical study was performed with the single factor within-subject design based on the feeling of the consumers' being threatened when the in-group was criticized by the others. The in-group threatened was accessed from the memory of each of the undergraduate students participating in the empirical study by asking them to remember the events by which their important in-group was perceived to be threatened in their past life. Questionnaire data collected from the undergraduate students were used to verify research hypotheses by structural equation model in Amos 21.0 program. Results: First, the self-definition positively affected the within-domain versus across-domain consumption, but did not affect the in-group system justification. Second, the self-investment positively affected the in-group system justification. Third, the system justification made positive effects on the within-domain versus the across-domain consumption. Therefore, this article could contribute to the development of the theory related to compensatory consumption in the view that there could be the positive mediation roles of system justification in the effects of consumers' self-investment to their in-group on the within-domain versus across-domain consumption when the in-group is threatened. Conclusions: The results of this study could give managerial implications to brand or product marketing managers. How to vitalize consumers' self-definition with, and self-investment to, the threatened in-group is at issue to the marketers when consumers' important in-group was threatened by others. By evoking the in-group-based self-investment to consumers when the in-group was threatened, the marketers should increase the level of the system justification, and the marketers should promote the consumers to recognize that their products or brands are included into the within-self domain.
