In this study, the factors affecting opportunism in the relationship between suppliers and key accounts were analyzed from the viewpoint of transaction cost theory, market power theory, and relationship marketing theory. As a result of the hypothesis test, Hypothesis 1 stating that demand volatility will have a positive effect on opportunism and Hypothesis 2 that transaction-specific investment will have a positive effect on opportunism were also supported. In addition, Hypothesis 3 stating that channel power will have a positive effect on opportunism was also supported. Lastly, Hypothesis 4 stating that relational commitment will have a negative effect on opportunism was not supported, along with Hypothesis 5 stating that transaction satisfaction will have a negative effect on opportunism. The theoretical and practical implications of this study are as follows. This study has identified the antecedents of opportunism by comprehensively applying the transaction cost theory, market power theory, and relationship marketing theory. In addition, this study can identify what a company should manage specifically to lower opportunism by identifying the antecedents of opportunism. The limitations of this study and the directions for future studies are as follows. First, not all of the antecedents of opportunism of key accounts have been extensively investigated from the viewpoint of the transaction cost theory, market power theory, and relationship marketing theory. In the future, it is necessary to identify additional factors. Second, the study was conducted only in the supplier's viewpoint. In future studies, it is expected that more accurate research results can be obtained by simultaneously examining not only the supplier's point of view but also the buyer's point of view.

The goal-gradient hypothesis states that the tendency to approach a goal increases with the increasing proximity of the goal (Hull 1932). It was initially supported with an evidence of animal experiments and since then, several papers have investigated the goal-gradient hypothesis in humans. Although there are some evidences related to the goal-gradient hypothesis in human behaviors, none of previous studies can properly explain its underlying mechanism, and what's more, they were not able to suggest useful managerial applications in human behaviors. From these perspectives, this work points out that there are some theoretical weaknesses to apply the goal-gradient hypothesis into the complicated human decision-making behaviors and proposes an alternative theoretical mechanismthat underlies the goal-gradient hypothesis in human. Finally, it offers insights into managerial implications of the goal-gradient hypothesis in the marketing field. This study focuses on the changes in motivations for achieving goals, in terms of how approaches to goals vary according to temporal distance from those goals. Specifically, the temporal construal theory (Liberman and Trope 1998) is considered as the underlying mechanism of the goal-gradient in that the temporal construal theory argues how the temporal distance from a goal makes people change their associated values regarding to that goal. According to the temporal construal theory, the value of distant future outcomes (near future outcomes) is construed on the basis of abstract and central features (concrete and peripheral features), and it argues that distant future situations are construed on a higher level than near future situations. This means that the value associated with the high-level construal is enhanced over delay, whereas the value associated with the low-level construal is discounted over delay. Our propositions suggest that the goal-gradient behavior in human can be motivated by the different aspects or characteristics of the goal as time changes based on the temporal construal theory. Thus, the following propositions are proposed. P 1-1: If the goal is far away, consumers put more value on the central features that are more associated with the desirability of the goal. P 1-2: If the goal is far away, consumers put more effort into accomplishing the goal that has more central features, regardless of its peripheral features. P 2-1: If a goal is near, consumers put more value on the peripheral features that are more associated with the feasibility of the goal. P 2-2: If a goal is near, consumers put more effort into accomplishing the goal that has more peripheral features, regardless of its central features. We hope to provide sufficient managerial implications for the companies as our research aims to show how consumers react differently as they progress toward the goal. Proposed propositions may provide guidance for companies developing a loyalty program, enabling them to understand what kinds of benefits or services they should provide or emphasize to consumers in loyalty programs on the basis of the time-dependent changes in outcome values (such as gifts, reward coupons). The effects of temporal distance from a goal should inform companies' marketing activities and help themto determine where emphasis should be placed in designing the benefits of their loyalty program.

In this study, we investigated students' responses to a discrepant event and an alternative hypothesis which had been presented in the conceptual change processes from the phlogiston theory to the oxygen theory, and compared them with scientists' responses. The data concerning scientists' responses to the discrepant event and the alternative hypothesis were gathered from the relevant literature on the history of science. Subjects were 148 eighth graders who possessed the target misconception about combustion through a preconception test. After having been presented with the discrepant event and the alternative hypothesis, students were asked to respond to the test of response to discrepant event. Although similar types of responses were obtained from both scientists and students, there was also a clear difference. Scientists tended to focus on explaining the problems of the discrepant event, whereas students tended to ignore and/or exclude the discrepant event in order to maintain their previous beliefs. Only a few students were also found to change their beliefs after having been presented with the alternative hypothesis.

${\ulcorner}$Hwangje-Naegyeong${\lrcorner}$ described Tae Hue(太虛) cosmos which consist of the Great Gi(大氣) produce ${\ulcorner}$Hwangje-Naegyeong${\lrcorner}$ which affected by the theory of activity of Gi(氣化說) in the Han period represent that Tae Hue is spring head of Gi(氣), concurrently said the Time and the Space were established by operating of Gi(氣). As of the Theories of heavenly structure, ${\ulcorner}$Hwangje-Naegyeong${\lrcorner}$ was write in long perod, so it include three branch theory. ${\ulcorner}$Hwangje-Naegyeong${\lrcorner}$ contained the Hypothesis of Covering Heaven(蓋天說), the Hypothesis of Armillary Sphere(渾天說) and the Hypothesis of Chaosheavens(宣夜說) in the Han perod. The Hypothesis of Covering Heaven(蓋天說) means that the sky is round and the ground falls Square(天圓地方). ${\ulcorner}$Hwangje-Naegyeong${\lrcorner}$ involve the Hypothesis of Covering Heaven by the fact that it divide heaven and earth by top and bottom. The Hypothesis of Armillary Sphere(蓋天說) is not directly appeared in ${\ulcorner}$Hwangje-Naegyeong${\lrcorner}$. But ${\ulcorner}$Hwangje-Naegyeong${\lrcorner}$ include the Hypothesis of Armillary Sphere by the astronomical observation and understand the universe with interior-exterior viewpoint. ${\ulcorner}$Hwangje-Naegyeong${\lrcorner}$ describe the circulation of the universe (周天度數) at 365 1/4 terms, the length of daytime and night of the vernal equinox and the autumnal equinox is same and use the The Twenty Eight Constellations by the ecliptic(黃道). It prove that ${\ulcorner}$Hwangje-Naegyeong${\lrcorner}$ observes the celestial body according to the Hypothesis of Armillary Sphere. The Hypothesis of Chaosheavens(宣夜說) appears most is the theory which lately. ${\ulcorner}$Hwangje-Naegyeong${\lrcorner}$ describe Tae Hue(太虛) infinite outer space and the earth is floating by Gi(氣). This with the Hypothesis of Chaosheavens is similar from like this point.

Shortfall risk is considered by taking some exposed risks because the superhedging price is too expensive to be used in practice. Minimizing shortfall risk can be reduced to the problem of finding a randomized test ${\psi}$ in the static problem. The optimization problem can be solved via the classical Neyman-Pearson theory, and can be also explained in terms of hypothesis testing. We introduce the classical Neyman-Pearson lemma expressed in terms of mathematics and see how it is applied to shortfall risk in finance.

This paper introduces a multilevel item-response-theory (IRT) model as a unifying model for hypothesis testing using legislative voting data. This paper shows that a probit or logit model is a special type of multilevel IRT model. In particular, it is demonstrated that, when a probit or logit model is applied to multiple votes, it makes unrealistic assumptions and produces incorrect coefficient estimates. The advantages of a multilevel IRT model over a probit or logit model are illustrated with a Monte Carlo experiment and an example from the U.S. House. Finally, this paper provides a practical guide to fitting this model to legislative voting data.

This study aimed to redefine the concept of fishing village tourism. In addition, it aimed to carry out detailed analyses of the influences of authenticity and non-authenticity of fishing village experience on tourist's satisfaction as well as the influences of tourist's experience on their satisfaction. The study evaluated responses of people who visited research target fishing villages in the East sea area(Hwasung-si Baegmi-ri) which had been rated as successful case. The evaluation was performed to analyze how tourist satisfaction would be influenced by the authenticity of the fishing village experience program based on the authenticity theory(Wang, 1999) and the experience realms theory(Pine & Gilmore, 1999). This study tried to find out realistic factors of the experience realms theory through field investigation, conducting interviews, and holding discussions. From these, the cause-and-effect structure of authenticity, tourism experience and satisfaction could be identified. The results of hypothesis tests are as follows; With respect to the relationship between authenticity and satisfaction in hypothesis I, authenticity did not have a statistically significant effect on satisfaction, while non-authenticity had a significant influence. As a result, the research hypothesis I that authenticity influences satisfaction was partially supported. Regarding hypothesis II of the link between authenticity and tourism experience, a significant effect of authenticity was found in education experience, entertainment experience for Baegmi-ri village. The effect of non-authenticity was significant on deviation experience. Consequently, hypothesis II was also partly supported. The relationship between tourism experience and satisfaction in hypothesis III was significant in education, entertainment, and deviation experiences which lends support to hypothesis III to some extent.

In this paper, we propose a new data clustering method using local probability and hypothesis theory. To cluster the test data set we analyze the local area of the test data set using local probability distribution and decide the candidate class of the data set using mean standard deviation and variance etc. To decide each class of the test data, statistical hypothesis theory is applied to the decided candidate class of the test data set. For evaluating, the proposed classification method is compared to the conventional fuzzy c-mean method, k-means algorithm and Discriminator analysis algorithm. The simulation results show more accuracy than results of fuzzy c-mean method, k-means algorithm and Discriminator analysis algorithm.

In this study, the factors affecting opportunism that causes conflict in the franchise system between franchisor and franchisee were analyzed based on the transaction cost theory and power-dependency theory. Hypothesis 1 states that franchisor support will negatively affect opportunism. Hypothesis 2 expresses that franchisee transaction-specific investment on the relationship with the franchisor will positively affect opportunism. Hypothesis 3 asserts that franchisee dependency on the franchisor will positively affect opportunism. All of these were supported. However, Hypothesis 4, maintaining that franchisee competitive intensity will positively affect opportunism, was not supported. The theoretical and practical implications of this study are as follows. This study has identified the antecedents of franchisor opportunism that causes conflict in the franchise system by comprehensively applying the transaction cost theory and power-dependency theory. This study can also identify what a company should manage specifically to lower opportunism by identifying the antecedents of franchisor opportunism in the franchise system. The limitations of this study and the directions for future studies are as follows. First, not all of the antecedents of franchisor opportunism in the franchise system have been extensively investigated from the transaction cost theory's and power-dependency theory's viewpoint. In the future, it is necessary to identify additional factors. Second, the study was conducted only from the franchisee's perspective. In future studies, more accurate research results can be obtained by simultaneously examining the franchisee's point of view and the franchisor's point of view.

In this study, the effect of reducing and increasing factors in relationship conflict on the relationship exit between auto parts suppliers and buyers was analyzed based on transaction cost theory and relational exchange theory. As a result of the hypothesis test, Hypothesis 1, which states that relationship commitment will hurt relationship exit, and Hypothesis 3 that replacement will harm relationship exit were supported. In addition, Hypothesis 2 which states that transaction-specific investment will positively affect relationship exit was not supported. The theoretical and practical implications of this study are as follows. This study has identified the antecedents of relationship exit by comprehensively applying the transaction cost theory and relational exchange theory. In addition, this study can identify what a company should manage specifically to lower conflict and relationship exit by identifying the antecedents of relationship exit. The limitations of this study and the directions for future studies are as follows. First, not all of the antecedents of relationship exits between auto parts suppliers and buyers have been extensively investigated in the viewpoint of the transaction cost theory and relational exchange theory. In the future, it is necessary to identify additional factors. Second, the study was conducted only from the supplier's viewpoint.
