The purpose of this essay is to converge the theory of communicative action Into the new paradigm of 'public relations democracy.' The notions of communicative action rationality, the public sphere, and deliberative democracy led new public relations paradigm approaches including meaning sharing, media access enlargement, and theoretical ramifications for the powerless. As Habermas prospected the power of comprehensive rationality to solve post-capitalist problems, the paradigm of public relations democracy visions the new era of public relations equipped with rhetorical and critical approaches. The new paradigm tries to overcome functional fallacy and embraces the concept of public interest. The paradigm of public relations democracy aims at integrating all three levels of public relations activities such as individual, organizational, and social levels, and pursues to enlarge the public sphere through increasing communicative actions and resolving social conflicts. Habermas's critical theory exhibits an opportunity for public relations theory building.

Today, the modeling of concrete as a material within finite element simulations is predominantly done through nonlinear material models of concrete. In current sophisticated computational systems, there are a number of complex concrete material models which are based on theory of plasticity, damage mechanics, linear or nonlinear fracture mechanics or combinations of those theories. These models often include very complex constitutive relations which are suitable for the modeling of practically any continuum mechanics tasks. However, the usability of these models is very often limited by their parameters, whose values must be defined for the proper realization of appropriate constitutive relations. Determination of the material parameter values is very complicated in most material models. This is mainly due to the non-physical nature of most parameters, and also the large number of them that are frequently involved. In such cases, the designer cannot make practical use of the models without having to employ the complex inverse parameter identification process. In continuum mechanics, however, there are also constitutive relations that require the definition of a relatively small number of parameters which are predominantly of a physical nature and which describe the behavior of concrete very well within a particular task. This paper presents an example of such constitutive relations which have the potential for implementation and application in finite element systems. Specifically, constitutive relations for modeling the plane stress state of concrete are presented and subsequently tested and evaluated in this paper. The relations are based on the incremental theory of elastic strain-hardening plasticity in which a non-associated flow rule is used. The calculation result for the case of concrete under uniaxial compression is compared with the experimental data for the purpose of the validation of the constitutive relations used.

Objectives: The purpose of this study was aimed to examine the effect of self-esteem on life satisfaction and happiness among adolescents, and to verify moderated mediation of peer relations mediated by altruism and self-regulation. Method: The study referred to the 2015 Annual Report of the Korean Children and Youth Panel Survey. More precisely, report on the fourth year research process of the study cohort comprising 2,091 subjects was used to verify the research model. Overall data were analyzed by using SPSS 18.0 program and specifically, moderated mediation were verified by using SPSS Macro, as suggested by Preacher, etc. (2008). Results: As a result, firstly, the peer relations mediated the relationship between life satisfaction and self-esteem among adolescents. Secondly, altruism and self-regulation had moderated mediation effects between self-esteem and peer relations among adolescents. Conclusion: These results suggest that self-esteem affects on life satisfaction and happiness by mediation of peer relations among adolescents and altruism and self-regulation agent is applied positive adjustment to further promote the peer relations and increase life satisfaction among adolescents. Through these study results, the implications for counseling and suggestions for future research were discussed.

The Gamma-Ray Bursts (GRBs) are classified into the long GRBs (LGRBs) and the short GRBs (SGRBs). Their progenitors are expected to be different because they have its own distinct characteristics. Occasionally, the SGRBs having faint extended emission (EGRBs) are observed. The EGRBs exhibit the analogous properties that the SGRBs have, but observed T90 of the EGRBs is longer than two seconds as the LGRBs. Because the EGRBs have characteristics of the LGRBs and the SGRBs, study of the EGRBs is important to understand origins of the GRBs. In this study, we obtain the luminosity relations of the EGRBs observed by Swift/BAT. We compare these results with luminosity relations on the LGRBs and SGRBs. In addition, we examine the spectral lag relations of spike and extended emission component of the EGRBs detected by CGRO/BATSE, Konus/WIND, Swift/BAT, Fermi/GBM and compare to each other. We find that the luminosity relations of the EGRBs present different results with the LGRBs and the SGRBs. In the spectral lag relations, extended emission component expresses opposite results compared with spike component. Furthermore, the spectral lag relations from the four instruments came up with different outcomes to each other.

The study examined the pathways from maternal reactions to children's negative emotions to children's peer relations through children's empathy and emotional regulation. The participants in this study comprised 463 elementary school 4th-6th graders. They completed questionnaires on maternal reactions to children's negative emotions, levels of children's empathy, maladaptive emotion regulation types and skill levels of children's peer relations. Data were analyzed by means of structural equation modeling. It was found that in the case of maternal emotion coaching reactions, when done indirectly, as well as directly, had an influence on their levels of peer relations. On the other hand, in the case of over-sensitive maternal reactions, when done indirectly, but not directly, had an influence on their levels of peer relations. Therefore, these results indicate that children's empathy mediated the effects of maternal emotion coaching and over-sensitive reactions on peer relations. It also found that there are distinct pathways from maternal reaction types to children's negative emotions to peer relations through empathy and maladaptive emotion regulation types.

The purpose of this study was to identify the relationship of interpersonal relations disposition, appearance concern, appearance management behavior of men through a structural study method. Three hypotheses were established to verify the relationships among interpersonal relations disposition, appearance concern and appearance management behavior. The questionnaires were administered in the city of Daegu to 201 males in their 20s to 50s. The SPSS 20.0 package was utilized for data analysis, which included frequency analysis, factor analysis, correlation analysis and Cronbach's ${\alpha}$. Also, Amos 21.0 program was utilized for a confirmative factor analysis( CFA) and a structural equation modeling(SEM) analysis. The results of this study are as follows; First, interpersonal relations disposition showed a positive influence on appearance concern. Second, appearance concern had a positive influence on appearance management behavior. Third, the interpersonal relations disposition showed a positive influence on appearance management behavior. In conclusion, interpersonal relations disposition, appearance concern, appearance management behavior of men are found to have a correlation.

Decision-makers in ecological system and social system have complex interactions and relations. Such interactions and relations are not predefined but dynamically constructed. We consider what relation-s are constructed or destroyed and how the relations change. Therefore, we focus on the formation and collapse of relations as one of the emergent phenomena of social or ecological complex phenomena. Game theory is the best way of analyzing phenomena in terms of interactions. However, it is difficult to analyze the dynamical system by game theory. Consequently, we propose Selecting Game with agents as players based on game theory. In this model, the relations among agents are not predefined but constructed by selecting subgames. As a result, we confirmed that the entire relation among agents is constructed by the agents＇ changing partial relations and that the relations dynamically change.

This study is to examine the transition of employment relations depending on labor reform by U Thein Sein Government(2011~2015) in company level and implemented literature review and interview. The results of this study are as follow. According to contents of the legislative amendment pursued by U Thein Sein government, there were some changes in employment relations as the use of standard labor contract, the application of paid holidays, easy use of vacations/sick leave and the establishment of trade unions. But, after the adoption of the minimum wage system, there was not change in the employment relations to such an extent as to have a significant impact on the live of the laborers. So it is expected that development of the trade union representing laborers in the future is able to take mutually beneficial employment relations.

This study examined how young children understand representational relations between referents and their representational objects. Ninety-four children aged 2- to 4.5-years of age were individually tested; firstly in the scale-model tasks, and then in the scale-map tasks. Data were analyzed both by means of Chi-Square test and by a more descriptive, micro analysis. According to the results, there were significant age differences in the understanding of representational relations, regardless of the type of representational objects. In the descriptive, micro analysis, it was found that before 3 years of age, young children have a great deal of difficulties in understanding representational relations. More importantly, young children under three seemed unable to understand representational relations, especially when the similarities as well as the differences between the representational object and the referent were very high. These results suggest that teachers of very young children need to select representational materials carefully, taking into consideration children's understanding of representational relations.

This paper suggests a method for verification of temporal relations on SMIL 2.0 document using an extended temporal interval model. The SMIL 2.0 document has more asynchronous temporal relations and supports more interactive relations between objects than traditional SMIL document. But it is higher to produce temporal inconsistency by various interactive relations between objects. So the suggested verification method expresses SMIL 2.0 document as functional relations based on an extended temporal interval model and verifies SMIL 2.0 document using interactive relations and temporal intervals between objects. Applications to the verification method are as follows; multiuser interactive contents, online-learning, etc.
