  • In this paper, we suggest a framework to represent the fuzziness in knowledge base as a perspective of the object-oriented paradigm. We divide the knowledge base in two parts. One is the object-base that stores the fuzzy propositions and the explanatory databases. The other is the rule-base that manages the rules between the fuzzy propositions. As the first step, we have to develop a new fuzzy object model that gives an easy way to represent the fuzzy propositions, that is, the fuzzy knowledge in the real world.

  • Purpose - Many variables are needed for brand loyalty such as brand attitude, brand attachment, brand love and brand commitment. Thus, we should manage these all variables successfully for strong and differentiated brand equity. This study aims to identify the process of how the brand value propositions affect the brand attitude and brand attachment. This study specially conceptualizes that not only utilitarian value and hedonic value influence the brand attitude but also hedonic value influences the brand attachment. This study focuses on the moderating role of consumer involvement such as cognitive involvement and affective involvement in the causal relationships among brand value propositions, brand attitude, and brand attachment. Research design, data, and methodology - The five hypotheses were proposed and tested in this study. Three hypotheses were about the relationship among the brand value propositions(utilitarian value and hedonic value), brand attitude, and brand attachment. The other two hypotheses were about the moderating effect on consumer involvement in the causal relationships among brand value propositions, brand attitude, and brand attachment. Research data were collected from the students of universities located in Daejeon-Si and Chungchungnam-Do. For the purpose of test the hypotheses empirically, the 208 responses were used. We utilized SPSS18.0 for statistical analysis such as reliability test, factor analysis, and regression analysis. Results - The results show that the utilitarian value and hedonic value have influence on the brand attitude positively. The results also show that the hedonic value has influence on the brand attachment positively. We found that there is a moderating effect on the cognitive involvement in the relationship between the utilitarian value and the brand attitude. However, there is no moderating effect on the affective involvement in the relationship between the hedonic value and brand attachment. In Summary, 4 of 5 hypotheses in this study were supported and 1 hypothesis was not supported. We should identify the reason why the hypothesis 5, the moderating effect of the affective involvement in the relationship between the hedonic value and brand attachment, was rejected in this empirical analysis. Conclusions - Both the utilitarian value and the hedonic value that propose a brand are important for brand attitude. Specially, the hedonic value is important for brand attachment. Companies should provide the consumers with both the utilitarian value and the hedonic value in a balanced way for their favorable brand attitude and strong brand attachment. In the retail industry, the balance between the utilitarian value and the hedonic value is important in that there are many product brands and store brands providing consumers with various benefit and values. Also, there are possibilities that the causal relationships among brand value propositions, brand attitude and brand attachment are moderated by consumer involvement such as cognitive involvement and affective involvement. Companies should understand and consider consumer involvement for their efficient and effective brand management decision making.

  • The successful development of science parks is dependent on the relevance and delivery of a range of value propositions they offer to their stakeholders. Experience has shown that the benefits of these value propositions are 'place based' and 'time dependent', influenced by the prevailing technology, social and business environments in which they operate, and the relationship that is developed between entrepreneurs, corporates, academia and government in creating these projects, and their performance is dependent on economic, physical and networking assets they create and deploy. This paper looks at some of the history that has influenced the development of parks, lessons learnt from their planning, development and operation. It reviews these details in the context of delivering value propositions in the context of temporal, spatial, technology and entrepreneurial profile of the new idea of 'innovation districts', influencing 'city planning' and supporting 'smart specialisation strategies'.

  • Physical Surroundings have been identified by a number of researchers as a powerful tool that can manipulate people's mood and cognition. A number of marketing practitioners have accepted this notion, given that physical surroundings are increasingly used as atmospheric stimuli in various retail environment as well as in restaurant. Yet there have not been practical reviews on consumer responses in restaurant setting/environment. By means of a literature review, this study examines how physical surroundings in restaurant settings function on displaying dinning atmosphere. It includes the conceptual definition and classifications of physical surroundings, effect of physical surroundings on customers' internal responses and behaviors, and testable research propositions and directions for future researches. This study is expected to make a substantial contribution to the understanding of restaurant manager and dinning atmosphere displayer about function of physical surroundings in dinning context.

  • In this article, We propose research propositions about correlates of job interest, job difficulty, job effort, and job performance as well as job performance and emotions while working. The purpose of this study is to review existing research on emotions and job performance, particularly emotions at work. The purpose of this article is to review existing research on job performance and emotions, particularly at the job relevant cognitions level. In this study, We propose research propositions about correlates of job performance and emotions while working. The purpose of this article is to develop and propose research propositions about potential correlates of perceived performance at the job relevant level. Correlates include those that should function mainly as antecedents of performance, such as job difficulty, job interest, and job effort in the study are emotions experienced concurrently with job performance. Therefore, We suggest the predictive direction and bivariate relationship of the set of among variables in explaining job performance and emotions.

  • Nash Equilibrium (NE) is essential to investigate a participant's bidding strategy in a competitive electricity market. The transmission line constraints make it difficult to compute the NE due to causing a mixed strategy NE instead of a pure strategy NE. Computing a mixed strategy is more complicated in a multi-player game. The competition among multi-participants is modeled by a two-level hierarchical optimization problem. A mathematical programming approach is widely used in finding this equilibrium. However, there are difficulties to solving a mixed strategy NE. This paper presents two propositions to add heuristics to the mathematical programming method. The propositions are based on empirical studies on mixed strategies in numerous sample systems. Based on the propositions a new formulation is provided with a set of linear and nonlinear equations, and an algorithm is suggested for using the prepositions and the newly-formulated equations.

  • This study suggests a process design using cognitive processes. Job characteristic model for job design and recent cognitive engineering studies for process design are reviewed briefly. By using these concepts, the lean production system is re-interpreted in terms of cognitive engineering and the latent dimensions of the lean production system are revealed as the application of cognitive engineering principles. An integrated process design framework for cognitive manufacturing system using job characteristic model is suggested for the effective design of manufacturing system. Propositions for empirical analysis of this model are also analyzed through a questionnaire survey. Propositions are (1) experiential cognition and motivation potential affect the ability, role perception, and need for achievement of the operator in the manufacturing system, (2) the ability, role perception, and need for achievement of the operator affect the job performance. Both propositions are supported by correlation analysis and path analysis.
