This research examines the effect of outside director system which has been legislated after financial crisis in Korea. Outside director system is based on agency theory which assumes that a manager is selfish and opportunistic in situation where ownership and management of a firm is separated. In this situation, outside director system has an important function to monitor and keep in check a manager. Thus, we examined that outside director system works as a monitoring mechanism in Korea. And we tested that above effect is weakened in family CEO firms where it is different from assumption of agency theory in Korea. According to empirical result with 282 sample firm, it is confirmed that outside director system reduces agency cost. In family CEO firms, however, this agency cost-reducing effect becomes weak. This result suggests that outside director system needs be cautiously managed without focusing on only monitoring function.

This study aims to explore factors of Assimilation Gap(AG) which is proposed and illustrated by Fichman and Kemerer(1997). AG is defined as the time delay between adoption and deployment and mainly studied at the organizational level. This study derives the factor affecting AG through a review of technology acceptance models and agency theory. The research model consists of three groups of independent variables(IT knowledge burden, Individual characteristics, and organization characteristics) and a moderator, which is goal incongruence. Using multiple regression analyses, four groups of hypotheses are tested with data of 221 knowledge workers from various organizations through e-mail survey. The result shows that radicalness(a dimension of knowledge burden), personal innovativeness, self-efficacy, and organizational support are statistically significant factors while complexity, experience, and perceived critical mass are not supported. The moderator effects of goal incongruence are found in personal innovativeness and organizational support. The results of this study demonstrate that agency theory is a useful perspective to deal with AG, especially in radical innovation. In addition, IT practitioners should consider not only user training but also incentives and possible organizational controls in implementing a new information technology.

The target strength (TS) is calculated from the measured signal using the definition of the peak TS (PTS) or the integrated TS (ITS). These two types of TS sometimes give different results depending on what the pulse duration is. In this paper, we model the scattered time signal by the numerical code based on the physical diffraction theory and examine the effect of the pulse duration on the value of PTS or ITS. The transformed TS (TTS) for the frequency domain is used as a reference solution.

Purpose - The current study aims to examine the effect of social network factors on travel agency employees' occupational outcomes such as job performance and job satisfaction through innovation behavior in a comprehensive model. Research design, data, and methodology - Based on a theory of social network, the concept of social network was assessed by three factors: a) network size, b) network range, and c) tie strength. To test the proposed hypotheses, structural equation modeling (SEM) was employed based on data from 197 travel agency employees in Korea. Result - The results showed that the associational activity of network size had a positive effect on innovation behavior, while the network range of network size had a significant negative effect on innovation behavior. Subsequently, innovation behavior positively influenced on job performance and job satisfaction, respectively. Conclusions - The results offer some insights into the extended model and have important managerial implications for Korean travel agencies. More specifically, considering diverse domains of social network and organizational research, this study advances critical utility of social network factors in a high facilitating level of innovation behavior, which can help travel agency employees promote their job performance and job satisfaction.

Radioactive iodine is a representative fission product to be quantified for the safety assessment of nuclear facilities. In integral severe accident analysis codes, the iodine behavior is usually described by a multi-physical model of iodine chemistry in aqueous phase under radiation field and mass transfer through gas-liquid interface. The focus of studies on iodine source term evaluations using the combination approach is usually put on the chemical aspect, but each contribution to the iodine amount released to the environment has not been decomposed so far. In this study, we attempted the decomposition by revising the two-film theory of molecular-iodine mass transfer. The model involves an effective overall mass transfer coefficient to consider the iodine chemistry. The decomposition was performed by regarding the coefficient as a product of two functions of pH and the overall mass transfer coefficient for molecular iodine. The procedure was applied to the EPICUR experiment and suppression chamber in BWR.

I investigate whether the efficient ratios used as the proxies of the agency costs maintained by Ang et al.(2000) is significant. Utilizing a sample of 77 manufacturing companies listed on the KOSDAQ from the TS2000 of the KSDA, The results are as follows. Agency costs are found to be decreasing with the ownership share of controlling shareholders and accounting performance becomes higher. But firm value measured by Tobin's Q ratio becomes lower according as the ownership of the controlling shareholders increases. If agency costs decrease in proportion to controlling shareholder's share, firm value should be higher according to the agency theory by Jensen and Meckling(I976). But the results of the empirical test of this study are inconsistent with Jensen and Meckling's(1976). Therefore the following study on the more useful proxies stand for agency costs should be needed.

The primary objective of the agency research in the game theory lives in the maintenance of Pareto is optimal condition for the optimal incentive contract. The basic concepts which are related to this objective are reviewed in connection with the general assumptions to model it, the moral hazard and adverse selection which arised from the information asymmetry, and finally the problem of risk distribution. The demand for auditing and the role of auditor have been addressed by ASOBAC. Issues which an auditor is explicitly introduced in a principal-agent framework have been addressed in this paper. These issues must be confronted to appropriately with the auditor, and to achieve an adequate understanding of optimal confronting arrangement with the auditor. The first step in introducing an auditor into this analysis is to examine the game-theoretic foundation of such a expended agency model. The Mathematical program formulated may not yield solution that are resonable. This arises because the program may call for the auditor and manager to play dominated Nash equilibra in some subgame. The nontrivial natures of the subgame implies that randomized strategies by the auditor and manager nay be of crucial importance. The possibilities for overcoming the randomized strategy problem were suggested; change the rule of the game and or impose covexity condition. The former seems unjustifiable in on auditing context, and the latter promising but difficult to achieve. The discussion ended with an extension of the revelation principle to the owner manager-auditor game, assuming strategies. An examination of the restriction and improvement direction of the basic concept of agency theory was addressed in the later part of this paper. Many important aspects of auditor incentives are inherently multiple-agent, multiple-period, multiple-objectine, phenomena and require further analyses and researches.

The shift in the perspective on learning as participation draws attention to learners' identity work. This manuscript foregrounds the ongoing and fluid processes of identity, and focuses on the structure surrounding learners where identity work occurs and the expression of individual agency. From the perspective of learning as participation, we introduce Holland et al. (1998) identity-in-practice theory, as the theoretical lens that dialectically describes structure, agency and identity. The concepts representing this theory are 'figured world', 'positionality' and 'authoring self'. The figured world is a web of meaning encompassing the continuous construct/reconstruct through human actions and also exerts as the social force that shapes human actions. 'Positionality' on the other hand, means an understanding of one's social position in the world. The notion of 'authoring self', is a dimension that synthesizes the above two concepts, which describes the improvisation of one's self through the orchestration and collaboration of various social voices. Next, we analyzed and described various cases of this theory that we found within the scope of science education. However, due to the nature of this theory, which takes a sociocultural approach, international research studies cannot be simply applied to the Korean context. Therefore, we sought to expand the applicability of this theory as a methodological tool, by discussing the directions in which this theory can be used in a domestic context. It is intended that the introduction of this theory, which emphasizes multi-layered, continuous and cumulative identity work, will be used as a resource to further expand the horizon of science education reform that is required for the times.

For the domestic web-toon industry, a new industrial environment has been created by the growth various domestic and international factors, such as technology development, the increase of platforms, charged web-toon, and globalization. Although the role of the agency has not been emphasized at the formation and introduction time of the web-toon, the role growth of the agency has been regularized with the expanding of the web-toon industry. The expending web-toon industry is due to the introduction of smart-phone, by which people can consume the web-toon without any limit of time and place, so the web-toon industry has been growing rapidly. Thereafter the production of the second contents using the web-toon IP has been actively carried out and the activity area of the web-toon artist has been diversified, so the necessity of the specialized web-toon agency has begun to be brought in earnest. In this study, the web-toon industry has been, firstly, classified as transition period of cartoon industry, foothold formation period of web-toon, introduction period of web-toon industry, expansion period, and maturity period according to the industrial life cycle theory. As a result, the web-toon agency has been emerged from the expansion period of web-toon industry, and the role of agency, to prevent web-toon industry entering into declining period from its maturity period, has been researched in this study.
