  • This paper describes a new process-plan selection method using a modified Fuzzy Quantification Theory(FQT). The problem of process-plan selection can be characterized by multiple attributes and used subjective, uncertain information. Fuzzy Quantification Theory is used for handling such information because it is a useful tool when human judgment or evaluation is quantified via linguistic variables, and the proposed method is concerned with the selection of a process plan by derivation of the values of categories for each attribute. In this paper, a modified Fuzzy Quantification Theory(FQT) is described and the procedure of this approach is explained and examples illustrated.

  • This paper deals with interpretation of pronouns in terms of Information Packaging Theory, proposed in Vallduvi(1994) and Engdahl and Vallduvi (1996), which depicts how discourse participants update new information, using three informational components: link, tail and focus. Based on empirical evidence, this paper argues that the information structure of an utterance is not enough for the hearer to process its information in accordance with the speaker's intention. It suggests that the hearer should be able to activate lexical file cards and frame file cards when necessary to designate the proper file card in which the information of the utterance should be recorded. It also proposes that, contrary to Vallduvi's claim, pronouns may create a new file card.

  • This paper empirically tests pecking order theory. Korean listed firms are used as the samples. On the whole we find supportive results for pecking order theory. The fixed effect model on the whole period shows that as pecking order theory suggests that debt ratio decreases as cash flow. ROA, physical assets, and firm size increase. Again, it is shown that corporate debt ratio significantly decreases as cash flow or ROA increases in every sub-sample, which coincides with the prediction of pecking order theory. Corporate debt ratio significantly decreases as physical assets or jinn size increases in case of the whole sample, pre-financial crisis period, and the sub-samples by q-ratio, which also supports the prediction of pecking order theory. Statistical significance of the coefficients of physical assets or firm size completely disappears after Korean financial crisis. Perhaps it is because the role of physical assets or firm size as a mitigator of information asymmetry significantly weakens after the financial crisis as Korean financial market becomes more transparent. For small firms only size variable is negatively and significantly related with debt to assets. It seems that size is an important factor for smaller firms in making financing decision.

  • In this paper, we proposed a generalized model reference adaptive control theory which can be applied to single-input single-output discrete system by using V.M.Popov's hyperstability theory. As the result of theoretical analysis, it is proved that the discrete adaptive control scheme proposed by Narendra is a special case of the adaptive control schemes proposed in this paper. Also we suggest a variety of parameter adaptiations methods of controller through hyperstability theory.

  • This study investigates design strategies for improving the educational quality of multimedia contents for early childhood education. It emphasizes both traditional education theory and developmental aspects in its exploration of interactive and educational qualitative multimedia contents for early children. Accordingly, for an effective early childhood education, it is necessary to experience of the playful learning for the conception of ideas and the understanding of the social life. Because this study 1) possibility of multimedia contents for early childhood education, 2) computer application method for early childhood education, 3) examines used in the designing of multimedia contents for early childhood education according to traditional education theory. Multimedia early childhood education system is possible to organize information such as test, image, sound and video based on hyperlink system. I use Microsoft's Ms-office and Asymetrix's ToolBook software that are useful for hyperlink and parameter. Multimedia contents and other pages are used by Dynamic Data Exchange(DDE). Therefore multimedia contents for early childhood education is a useful tool for students of early childhood education department, parents, and children.

  • Degree distribution can provide basic information for structural characteristics and internal relationship in social network. It is a critical procedure for social network topology analysis. In this paper, based on the mean-field theory, we study a special type of social network with exponential distribution of time intervals. First of all, in order to improve the accuracy of analysis, we propose a spreading coefficient algorithm based on intimate relationship, which determines the number of the joined members through the intimacy among members. Then, simulation show that the degree distribution of follows the power-law distribution and has small-world characteristics. Finally, we compare the performance of our algorithm with the existing algorithms, and find that our algorithm improves the accuracy of degree distribution as well as reducing the time complexity significantly, which can complete 29.04% higher precision and 40.94% lower implementation time.

  • Bargaining theory with asymmetric information is widely accepted to explain labor disputes. Even though it secures theoretical consistency, it needs to be supplemented to explain disputes and negotiation more accurately. This paper shows that it may be assisted by bargaining theories based on the economics of psychology as well as theories on bargaining practices which are popular in other academic fields. The former suggests the occurrence of asymmetric information is related with the perception of the players of bargaining. The latter does they do not exchange offers as the typical theory of bargaining with asymmetric information assumes. When the latter is applied to explain the labor disputes of the public sector, it explains clearly their features and the differences from those of the private sector.

  • Objective : This paper introduces a unique meridian theory developed by Japanese philosopher Yuasa Yasuo. Method : His meridian theory is well organized in his philosophy, so we systematically review his major works and philosophy from which we systematize his meridian theory. And we critically examine it with current studies. Results and Conclusions : He tried to overcome Cartesian mind-body dualism by Eastern thought and newly developing neurophysiology. He articulated "body scheme" from human information systems, primarily nervous system and meridian system, which regulate physiological functions. It consists of 1st external sensory motor circuit, 2nd circuit of coenesthesis, 3rd emotion-instinct circuit and 4th circuit of unconscious quasi-body. Meridian system is the 4th circuit, through which he thought various affect(emotion) flows. Based on the relationship of emotion-autonomic nervous system- meridian-skin, he tried to confirm the existence of meridian system. His theory illuminates mind-body problem and emotion-meridian relationship in traditional East Asian medicine.

  • This research derived the influencing factors for employees' compliance with the information security policy in organizations on the basis of Neutralization Theory, Theory of Planned Behavior and Protection Motivation Theory. To empirically analyze the research model and the hypotheses, data were collected by conducting web survey, 194 of 207 questionnaires were available. The test of causal model was conducted by PLS. Reliability, validity and model fit were found to be statistically significant. the results of hypotheses tests showed that seven ones of eight hypotheses could be accepted. The theoretical implications of this study are as follows : 1) this study is expected to play a role of baseline for future research about employee compliance with the information security policy, 2) this study attempted interdisciplinary approach through combining psychology and information system security research, and 3) it suggested concrete operational definitions of influencing factors for information security policy compliance through comprehensive theoretical review. Also, this study has some practical implications. First, it can provide the guideline to support the successful execution of the strategic establishment for implement of information system security policies in organizations. Second, it is proved that the need for conducting education and training program suppressing employees. neutralization psychology to violate information security policy should be emphasized in the organizations.
