  • The purpose of this study is to investigate the relationships among the beliefs of parents and children, children's cognitive and emotional behavior based on cognitive and interreactionary approach models. The Subjects were 138 children (68 eight-year-olds and 70 eleven-year-olds) and their parents. Instruments used in this study were the modified Family Belief Interview Schedule(Alessandri & Wozniak, 1987), the Standard Achievement Test, and Harter's Perceived Competence Scale. Data analysis was by Pearson's r product moment correlation, two-way ANOVA, Fisher-Z test and Student-Newman-Keuls post-hoc test. The major findings are as follows: (1) The beliefs of parents and children has a significant influence children's perception of competence. (2) The congruence of parents' and children's beliefs was hightest in "assumed similarity". (3) Mother's positive view of their children and congruence of mother's and father's beliefs were correlated with children's academic achievement. Parents' positive beliefs and congruence of beliefs were also correlated with children's self-perception of competence.

  • The purpose of this study was to identify the determinants of purchasing non-deceptive counterfeit luxury brands. As determinants, this study exmained subject-related variables(consumer ethnoncetrism and attitude toward counterfeit), product-related variable(similarity with originals), and social influence(social recognition by others). Data were gathered by surveying university students living in Seoul metropolitan area using convenient sampling, and 323 questionnaires were used in the statistical analysis. In analyzing data, confirmatory factor analysis and path analysis were conducted using structural equation modeling. Results showed that consumers' attitudes toward counterfeits significantly influenced their attitudes toward purchasing counterfeit luxury brands which directly influence purchasing frequency of counterfeit luxury brands. Consumers who evaluated the counterfeit more similar to the originals had more positive attitudes toward purchasing counterfeit luxury brands. The results show why consumers have increasing demands for counterfeits and the implications for anti-counterfeit business are suggested.

  • In this paper, we examine the points of similarity and difference between Korea, Japan, and the USA in terms of the spin-off effects of space technology on cultural life. In Japan and the USA, spin-off effects of space development research by government funded research centers are diffusive while in Korea they are interruptive. Spin-offs of research results impact cultural life via technology transfer and commercialization in businesses. This is because the Korean aerospace industry has progressed largely based on an overall system, but the promotion of internal parts and sub-systems, which can trigger technological development and spin-off effects in manufacturing, has been neglected. In the case of the KARI, the government funded research center, we argue that it is necessary for KARI to devote more resources to transfer (or promote spin-offs of) space technology to small and medium-sized businesses and other industries.

  • Euler method is generalized to solve the system of nonlinear differential equations. The generalization is carried out by taking a special constant matrix S so that exp(tS) can be exactly computed. Such a matrix S is extracted from the Jacobian matrix of the given problem. Stability of the generalized Euler process is discussed. It is shown that the generalized Euler process is comparable to the fourth order Runge-Kutta method. We also exemplify that the important qualitative and geometric features of the underlying dynamical system can be recovered by the generalized Euler process.

  • This study presents the pattern and determinants of intra-industry trade in Korea's machinery and transport equipment industry focusing the influence of foreign direct investment on intra-industry trade. Using an OLS regression model the determinants of intra-industry trade are investigated. Results indicate that a statistically significant negative relationship is found between intra-industry trade and foreign direct investment, and show that intra-industry trade is positively affected by the degree of product differentiation and export structure similarity. Intra-industry trade is also positively associated with the economies of scale, the level of trade barrier, and transportation costs, although this is not statistically significant. The study found strong evidence that the propensity of foreign direct investment toward export specialized industry makes the negative relationship between intra-industry trade and foreign direct investment.

  • Nowadays, the increasing global competition forces manufacturing enterprises to apply new technologies such as laser welding to manufacturing of their products. In case of automotive industries, they interest in assembly system for BIW (Body in White) carrying out laser welding. In this paper, the method of implementation for digital laser welding assembly system is proposed. Based on the requirements of assembly tasks obtained through product analysis, process modeling is executed by using the IDEF0 and UML model. For digital assembly system, the selected components are modeled by using 3D CAD tools. According to the system configuration strategy, lots of the alternative solutions for the assembly system of welding side panels are generated. Finally, the optimal laser welding system is chosen by the evaluation of the alternative solutions with TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method.

  • The region containing 18S rRNA gene, ITS 1 and part of the 5.8S rRNA gene of the Atractylodes japonica Koidz was amplified by PCR and the product cloned in a pBluescript SK II plasmid. DNA sequence of the cloned DNA was determined and submitted to the GenBank (accession number EU678363). Phylogenetic analysis of the ITS 1 DNA showed close similarity with the other plant species of the family Compositae. The extract of the plant materials of five different members of the family Compositae was analyzed by HPLC to detect atractylon. Extract of the A. japonica Koidz showed presence of significant amount of atractylon. However, noticeable amount of atractylon was not detected by the same analyses from the extracts of the other plants belonging to the family Compositae including Artemisia capillaris, Chrysantemum zawadskii, Eclipta prostrata or Taraxacum platycarpum.

  • This paper aims to explore the analysis of the meanings and processes of reading online consumer reviews and to construct a substantive theory that explains the process involved with the phenomenon of reading consumer reviews. In order to explore the phenomenon, this study employs a qualitative methodology. Following the grounded theory perspective, the researcher conducted interviews with 17 participants, who have subsequently shopped online and utilized online consumer reviews for shopping, and decidedly employed in-depth interviews with those participants. Through coding and making constant comparison, several themes emerged: improving confidence, trusting reviews, getting a sense of who reviewers are, seeking balance, processing and handling negative reviews, experiencing vicariously, increasing searchability, getting a sense of who they are in terms of similarity, and seeking benefits and the usage situations from consumer based reviews. Among the emerging themes, improving confidence can be considered a core category, which is influenced by the analysis of trusting reviews and the consumer vicarious experiences with a product. Moreover, this study discusses the relationships among the themes. This study concludes with a discussion of the results, implications, and limitations.
