To attain competitiveness in the severe competition of retailing, retailing firm like Aekyung department store composites multiplex entertainment shopping mall with other firms as key tenants like LG supermarket, Books Libro, and CGV. But in multiplex entertainment shopping mall customers who have experienced a service failure in key tenant's shops usually ask a compensation of service failure to the lessor like department store. Even though customers of multiplex entertainment shopping mall know that key tenants use different service strategy, personnel management system and operation system and so on, they do not rare of it. Why they do that? How can we explain this situation? This study explains customer's complaining behaviors in multiplex entertainment shopping mall using attribution theory and justice theory. The study presents a comprehensive model about the effects of the perceived attribution and fairness on customer satisfaction and suggests practical implications for retailing firms composing multiplex entertainment shopping mall.

In this paper, we investigated a Value-at-Risk approach to the volatility of two crude oil markets (Brent and Dubai). We also assessed the performance of various VaR models (RiskMetrics, GARCH, IGARCH and FIGARCH models) with the normal and skewed Student-t distribution innovations. The FIGARCH model outperforms the GARCH and IGARCH models in capturing the long memory property in the volatility of crude oil markets returns. This implies that the long memory property is prevalent in the volatility of crude oil returns. In addition, from the results of VaR analysis, the FIGARCH model with the skewed Student-t distribution innovation predicts critical loss more accurately than other models with the normal distribution innovation for both long and short positions. This finding indicates that the skewed Student-t distribution innovation is better for modeling the skewness and excess kurtosis in the distribution of crude oil returns. Overall, these findings might improve the measurement of the dynamics of crude oil prices and provide an accurate estimation of VaR for buyers and sellers in crude oil markets.

So far, there have been studies to verify the effectiveness of creative advertising contents, but there have been few studies explaining why creative advertisement contents are effective in consumer cognitive processes. The purpose of this study is to examine the effect of creativity of ad contents on desire to postpone cognitive closure and ad attitude. Furthermore, the cause of the advertising effect of the creative advertisement contents was set as disfluency and the relationship between the related variables was verified. Research has shown that creative advertising does not directly produce positive advertising attitudes, but it also forms ad attitudes through mediating effects of disfluency. In addition, it was found that disfluency mediated the desire to postpone cognitive closure in creative advertising. In summary, this study finds that the disfluency of advertising is an important variable for enhancing the advertising effect of creative advertisement. This study verified the advertising effect of creative advertisement by connecting it with consumers' cognitive variables.

According to the Fregean theory of meaning based on the distinction between sense and reference,the cognitive significance of coreferential names may be distinct or The so-called direct reference theorists. however,claim that unamhbiguous,coreferential names.which have the same denotation from context to context, must have the same cognitive significance.Thereby,Fregean senses,counted as intermediate entities that determine the denotation of a term,are altogether rejected.Once Fregean senses are rejected.however,it is hard to explain why the substitytivity of coreferential names fails in the contexts of propositional attitudes.Thus,the puzzles of propositional attitudes have been the stumbling block for direct reference theorists. Recently, Zalta claimed that by small amendation it is possible to reconcile the conflicting views of Fregeans and the direct reference theorists without losing their important insights.Indeed, he claimed that his suggestion admirably solves the propositional puzzles.In this article,we shall critically examine his eclectic solution only to highlight some of the more basic issues.

As the use of social media has gained mainstream popularity, concerns on the particulars of the users' motivation and method of use is on the rise. Under uses and gratifications approach, this study analyzes the use behaviors in Kakao-story, Facebook, and Twitter, and analyzes the changes in the perception of social support by the users of the media. Data was analyzed from 240 online questionnaire surveys. The study finds that the frequency of use of social media differs depending upon the personality of the users and their purpose of use, both of which also influence their type of use. It also finds that frequent use of social media increased the users' perception of social support, whereas their type of use had no effect with such perception. Communication behavior through social media seem to increase perception of social support.

The purpose of this study was to explore whether the concept of amount of invested mental effort (AIME) developed in the field of educational psychology can help explain why people put so little effort into online searching. In this experimental study, two information retrieval systems - a web search engine and a university library system - were used to make a comparison. The data were collected from 15 undergraduate students through background questionnaires, think-aloud protocols, search logs, post-search questionnaires, and post-task interviews. The findings indicate that perception of the web's "easy-ness" and high levels of self confidence in searching capability led the subjects to put less effort into web searching than they do into library system searching. In addition, the perceived difficulty of search task influenced the extent of mental effort invested. The AIME proved a useful framework for understanding search behavior and user experience for both web search engines and library systems.

In this study, a new reaction system is proposed to solve the problems of the existing 2,3-Butanediol (2,3-BDO) dehydration reaction system. It was confirmed that the reaction system did not wok as it should operate properly when using a furnace, which is commonly used in commercial processes, to raise the reactant, 2,3-BDO, to the reaction temperature, 360 ℃, at near atmoshperic pressure. It is because of the substance considered to be oligomers of 2,3-BDO. It can lead to safety problems, such as blockages inside the furnace's tube and explosions, as well as tricky maintenance issues in the reaction system. To solve it, the temperature of reactant can be brought down by using a heat exchanger with High Pressure (HP) steam instead of the furnace, which has a hot spot problem through the vacuum operation and reduce the reaction temperature. It can be seen that the reactor performance is almost similar under the vacuum operation and the lower reaction temperature, 330 ℃, by using a reaction kinetics. This result explains why the new reaction system is proposed.

The purpose of this study is twofold. First, it shows how to calculate the size of nonregular workers in Korea using the supplemental surveys to the Economically Active Population Surveys. Second, it decomposes the difference in the share of nonregular workers between 2005 and 2013 by a Oaxaca-type method.. The obtained results indicate that the differences in coefficients rather than the differences in characteristics are mainly responsible for the decline in the share of nonregular workers. This implies that a worker with the same characteristics is more likely to be a regular worker in 2013 than in 2005. This tendency may come from the changes in workers's as well as firms' employment practices. Also, it is suspected that the Nonregular Worker Act enacted in 2007 may have contributed to the decrease in the share of nonregular workers.

Recently, several studies in the field of privacy research suggested counterintuitive phenomenon about previous studies on existing perspectives. They claim that consistency of attitude and behavior does not exist, which is called privacy paradox. This study aims to clarify the relationship between intention to information disclosure and actual behavior based on the privacy paradox perspective. It attempts to explain the causes of privacy paradox phenomenon through the dual process theory being discussed in the field of behavioral economics. The results of empirical analysis are as follows. First, paired t-test analysis between intention to information disclosure and actual behavior was statistically significant. This means the existence of privacy paradox. Second, privacy risk had significant explanatory power to behavioral intention, and privacy trust had significant explanatory power to actual behavior. In conclusion, this study shows that negative belief influences decision making situation controlled by rational thinking whereas positive belief influences actual situations controlled by intuitive thinking.

왜 자판기 커피가 못 마실 음료처럼 비난을 받아야 하죠? 일부 미니 커피자판기에 사용된 원료 문제를 마치 전체 자판기 문제인 냥 떠들어 때는 매스컴이 정말 원망스럽습니다. -자판기 운영업자 K씨- A급 원료를 쓰고 있는데도 불구하고 마치 죄인 마냥 '멜라민 커피프림을 쓰지 않는다'는 해명문구를 써서 부쳐야 하니 정말 열불이 나더군요." -자판기 운영업자 P씨- 올 가을은 그야말로 중국산 멜라민 파동이 식품 업계 전반이 휘몰아친 한해였다. 해태제과의 '미사랑 카스타드'로 불붙은 멜라민 파동은 제작 전반을 걸쳐 자판기 커피프림 분야로도 불똥이 튀었다. 식품의약품안전청은 중국산 커피프림 원료를 수입하는 3개 업체의 10개 제품을 조사한 결과, 유창FC의 '베지터블 크림 파우더 F25에서 멜라민 1.5ppm이 나왔다'고 밝혔다. 이 크림은 41톤이 수입되어 25톤이 시중에 팔려나갔으며, 주로 자동판매기용 믹스커피나 커피전문점에 사용한 것으로 보도가 되어 일파만파로 파문이 확산되었다. 대부분의 매스컴 보도는 '자판기 커피프림에 멜라민이 들어갔고, 그래서 마셔서는 안 된다'는 식으로 과당보도가 되다 보니 소비자들의 분노의 불신이 걷잡을 수 없이 커졌다. 이에 자판기 커피 매출을 뚝 떨어 졌고, 그 동안 애용했던 자판기 커피에 등을 돌리는 사람들이 많아 졌다. 마치 자판기 커피가 식품안전을 위협하는 원흉이나 되는 듯한 분위기였다. 그런데 이런 뜻하지 않은 악재가 자판기 업계로 보면 억울하기 그지없는 일이다. 이번에 문제가 된 것은 식당 등에 설치된 '미니 커피자판기' 일부에 해당되는데도 불구하고 매스컴 보도는 전체 자판기가 문제가 된다는 식이었다. 대다수의 매스컴이 미니 커피자판기와 대형 커피자판기를 구분하는 개념도 없다보니 문제가 없는 대형 자판기를 불똥이 튈 수밖에 없었다. 또한 미니 커피자판기에서 그런 원료가 투출되기 쉬운 열악한 사업특성에 대해서도 언급을 하지 않았다. 일부분의 문제를 '침소봉대'하여 전체의 문제인 것처럼 보도하는 매스컴의 무책임한 태도가 가뜩이나 어려운 자판기 산업계에 직격탄을 날렸다. 대다수의 자판기, 특히 대형자판기들은 억울하기 그지없는 일이다. 이번 커피자판기 멜라민 사태를 통해 과연 매스컴 보도가 무엇이 잘못되었고, 산업계에 어떠한 과제를 내던졌는지를 심층 진단했다.
