This study was intended to examine the structural relationship between fan citizenship and sports marketing achievement. For that, 220 questionnaires were distributed to the fans of Lotte Giant in Busan region and 205 questionnaires were used finally. The hypotheses were validated by using SPSS 25.0 and Smart PLS 2.0 based on the study model. All hypotheses were adopted, except for 4 hypotheses(Hypothesis 5-3, Hypothesis 6-1, Hypothesis 6-2, and Hypothesis 6-3), among a total of 17 hypotheses. For that, the results were derived as below: First, fan citizenship had a positive(＋) influence on team equity(Hypothesis 1), sponsor assets(Hypothesis 2), and community equity(Hypothesis 3) as a whole. Second, team equity had a positive(＋) influence on sponsor assets(Hypothesis 4) in all respects, and furthermore, had a positive(＋) influence on local image(Hypothesis 5-1) and contribution to local community(Hypothesis 5-2). Meanwhile, team equity did not have a statistically significant influence on social interchange(Hypothesis 5-3. Finally, sponsor assets and community equity were found to have the relationship as follows: No statistically significant relationship was observed between corporate image and community equity. Corporate awareness had a positive(＋) influence as a whole. The results of this study are expected to provide comprehensive understanding and theoretical and practical implications of the influence that fan citizenship would have on sports marketing achievement.

Much of literature on the paradoxes of confirmation has been focused on the problems raised by the fact that a nonblack nonraven confirms the hypothesis that every raven is black. In this paper I would like to emphasize that more interesting problems are still waiting to be explained, if we notice that a black nonraven confirms the raven hypothesis as well. For this I examine what Hempel exactly means by the paradoxes of confirmation, and show that the previous discussions on the paradoxes were at most partial solutions. Then I argue that Hempel presupposes the so-called 'converse consequence condition' regarding confirmational evidence. Finally I discuss what impact is made on the Bayesian solution to the paradoxes, if we accept a more faithful interpretation to Hempel.

This study examines the effects of social commerce service quality and the service provider's physical environment on customer loyalty based on trust and satisfaction. Study results are as follows: First, correlation analysis results for social commerce service quality and social commerce trust find that informativity and interactivity exert statistically significant effects on social commerce trust. Second, service provider's physical environment and service provider satisfaction correlation analysis results demonstrate cleanliness, ambience, and interactivity exert statistically significant effects on service provider satisfaction. Lastly, the correlation between social commerce trust, service provider satisfaction, and social commerce loyalty, was statistically significant. Results of this study are expected to provide general understanding of group purchase decisions in social commerce and to provide value input in strategy development for social commerce with respect to group purchase and service provider.

Mutual Savings Banks generally have weaker governance structure than other financial institutions, so the possibility of earnings management by owner-largest or managements of mutual savings banks is higher than other financial institutions. This study examines the relationship between corporate governance and quality of internal control of financial reporting. If the expropriation of minority shareholder hypothesis holds, we predict that the larger block shareholder in mutual savings banks, the weaker the internal control system by more likely the opportunistic earnings management by bank managers. On the other hand, under the convergence of interest hypothesis, we predict that the larger block shareholder in mutual savings banks, the stronger the internal control system by reduction in agency costs as owner-manager's holdings increases, and there a negative relationship is expected between internal control weakness and the holdings of the owner-largest shareholder. We find that mutual savings banks with higher owner-largest shareholder equity has significant positive relations with their internal control of financial reporting material weakness. This result suggests that the greater owner-largest shareholder equity, the more likely the opportunistic earnings management, so that decrease quality of internal control. This paper extends the literature on financial institutions corporate governance to verify whether governance system, especially, owner-largest and quality of internal control has significant positive relations.

The purpose of this study is to investigate the teaching methods of prediction, inference, and hypothesis. The major data source was gathered by in-depth interview of science teachers (about 50-80 minutes for each interview). The interviews were conducted using semi-structured interview protocol, which consisted of three major parts: (1) Teacher's definition of prediction, inferences, hypothesis, (2) Teaching methods of prediction, inferences, and hypothesis and (3)Reasons of teacher's inaccurate perceptions of prediction, inference, and hypothesis. All the interviews were audio-taped and transcribed. Topics in the questions were categorized. The results were as follows: Teachers recognized the importance of prediction, inferences, and hypothesis. But they didn't have an accurate conception and they have great difficulty in classifying and explaining the prediction, inferences, and hypothesis. To find out the teaching methods, researcher investigated the inquiry activities, teaching times, usage of terms, teachers' questions, and teaching difficulties. Reasons for having difficulty were lack of teaching competency, difficulties from the students, and problems in the present curriculum. Finally, we discovered that the reasons for teacher's inaccurate perceptions of prediction, inference, and hypothesis were two factors. One is internal factors, which include the lack of scientific inquiry process skills, burdens of science subject and lack of science education knowledge. The other is external factors, which include education system for evaluations and lack of teacher education. In conclusion, this study suggested establishing more elementary teacher education programs that include strengthened concepts of inquiry process skills and teaching methods.

1997년의 경제위기는 근본적으로 많은 차입금에도 불구하고 장기간에 걸쳐 낮은 수익성을 보인 기업들이 불황에 직면하여 도산위험이 급증함으로써 발생한 것으로 판단된다. 그러면, 기업들의 수익성은 왜 이렇게 낮은 것일까? 본 연구는 지배대주주와 소액주주간의 갈등이 기업의 수익성을 저하시킨 한 원인으로 작용했다는 가설을 실증적으로 규명하고자 한다. 우리나라 기업들, 특히 기업집단의 경우 지배대주주의 개인소유지분은 높지 않지만 기업경영에 대한 통제력은 매우 강하다. 기업경영에 대한 감시와 책임경영이 확립되지 않는 경제에서 지배대주주가 기업자산을 개인적 이익에 따라 운영하는 경우 편익은 독점하지만 이에 따른 수익성 하락 등의 비용은 다른 주주와 소유 지분율에 따라 공유하게 되므로 사적이익을 추구할 유인이 크다. 본 연구는 1992년부터 1997년까지의 공기업 및 금융기관을 제외한 외부감사대상기업의 재무자료를 기초로 영업이익률, 경상이익률, 그리고 순이익률이 주주간의 이해상충에 의해 어떻게 영향을 받았는가를 분석하였다. 수익성 분석에 있어 상장여부, 자산운영(관계회사 및 비관계회사에 대한 투자), 재벌소속 여부, 기업규모, 재무구조 그리고 산업적 특성 및 기업의 경영 및 사업 전략적 특성을 제어하였다. 다른 조건이 동일하다고 가정하면 상장된 기업의 수익성은 비상장기업보다 낮다. 상장기업의 경우는 대주주의 소유지분이 낮은 반면에 외부주주의 비중이 높기 때문에 대주주가 개인의 이익을 추구하고자 하는 유인이 강하게 작용한 결과로 판단된다. 또한 재벌에 소독된 기업의 수익성은 독립기업들의 수익성보다 낮을 뿐만 아니라 계열회사의 유가증권 및 대여금 등에 대한 투자가 증가할수록 기업의 경상이익률 및 순이익률이 낮아진다. 반면에 비관계회사에 대한 투자자산은 경상이익률 및 순이익률을 높이는 것으로 나타났다. 재벌에 소속된 상장회사가 관계회사에 투자하는 경우는 투자기업의 수익성이 더욱 낮아지는 것으로 나타났다. 관계회사에 대한 투자는 수익성에 기초한 투자가 아니며 대주주의 지분이 낮은 상장기업에서 소액주주의 이익에 반하여 계열사에 대한 투자형태로 자원이 이전되고 있음을 시사한다. 본 논문의 분석 결과는 외부주주와 내부주주간의 이해상충이 기업의 수익성을 저하시킨다는 가설과 일관된다. 따라서 대주주가 개인적 이익을 추구하고자 하는 유인을 견제하고 소액주주의 권리를 강화하도록 지배구조를 확립해야 할 것이다.

This study is about the exhibition and convention visitors' satisfaction level and the participating companies' perception on the performance. The two topics were approached with integrated model. Accordingly, this study examined how service quality and experiential quality affect exhibition and convention visitors' satisfaction level and the participating companies' perception on the performance, and how the correlation between exhibition and convention visitors' satisfaction level and the participating companies' perception on the performance is affected. The result demonstrates that the quality of experience exerts positive effect on the visitors' sense of satisfaction(Hypothesis 3), while service quality is not statistically significant when it comes to the visitors' satisfaction(Hypothesis 1). When the correlation between service quality and experiential quality, and the participating companies' perception on the performance is examined, service quality exerts positive effect on the participating companies' perception on the performance(Hypothesis 2), while experiential quality is not statistically significant on the participating companies' perception on the performance(Hypothesis 4), When the correlation between exhibition and convention visitors' satisfaction level and the participating companies' perception on the performance is examined, it was shown that positive effect is exerted just like the results of the previous studies(Hypothesis 5), lastly, correlation between participating companies' perception on the performance, companies' satisfaction and company loyalty was examined. In case of the participating companies' perception on the performance, it exerts positive effect on the companies' satisfaction(Hypothesis 6), while company loyalty is not statistically significant (Hypothesis 7). In case of companies' satisfaction, it exerts positive effect on the company loyalty (Hypothesis 8). The results of this study will provide help to increase overall understanding of the exhibition and convention visitors' satisfaction level and the participating companies' perception on the performance, and to provide important implications for the development of strategy for exhibition and convention's vitalization.

There has been discussions and investigation on the nexus between religion and citizen's supports for suicide attacks and terrorist groups conducting such acts. In terms of the relationship, there were two potent hypotheses attempting to explain the process and mechanism of the relationship: religious belief hypothesis and coalitional commitment hypothesis. previous studies examined these hypotheses have been carried out across different cultural, religious, and political contexts. Until today, however, there are still lack of concrete evidence, which is generated from empirical studies, supportive evidence for any of these hypotheses. Therefor this study aims to investigate the association between religion and popular support for suicide attacks by using a survey data collected from three middle east countries, Egypt, Morocco, and Pakistan. In analysis, a step-wised regression analysis conducted with a set of variety of variables considered to be related with the association. This study found that variables reflecting religious belief hypothesis, such as prayer to God, religious devotion were unrelated to support for suicide attacks. Yet, prayer time predicted reduced supports for suicide attacks. Further, attendance at religious services, thought to enhance coalitional commitment, predicted support for suicide attacks. Yet, it showed negative association with support for suicide attacks. These findings suggest that regular attendance at religious services and regular prayer have combined effects reducing on the willing to support for suicide martyrdom. However, this study findings affirmatively support for neigher religious belief hypothesis nor coalitional commitment hypothesis. Instead, it suggests the needs for further research examination on the relationship as well as corrections of these hypotheses. Finally, Implications for the research findings for preventing suicide attacks are discussed.
