Online reviews play a significant role in consumer purchase decisions on e-commerce platforms. To address information overload in the context of online reviews, factors that drive review helpfulness have received considerable attention from scholars and practitioners. The purpose of this study is to explore the differential effects of discrete emotions (anger, disgust, fear, joy, sadness, and surprise) on perceived review helpfulness, drawing on cognitive appraisal theory of emotion and expectation-confirmation theory. Emotions embedded in 56,157 hotel reviews collected from TripAdvisor.com were extracted based on a transfer learning model to measure emotion variables as an alternative to dictionary-based methods adopted in previous research. We found that anger and fear have positive impacts on review helpfulness, while disgust and joy exert negative impacts. Moreover, hotel star-classification significantly moderates the relationships between several emotions (disgust, fear, and joy) and perceived review helpfulness. Our results extend the understanding of review assessment and have managerial implications for hotel managers and e-commerce vendors.

The purpose of this study was to construct a hypothetic model for the influential theoretical variables for the facial cosmetic resurgery intention of female college students with cosmetic surgery experience and to examine the compatability of the re-surgery intention model with real data. The subjects in this study were 320 selected female college students who had undergone cosmetic surgery. After a survey was conducted from July 15 to September 20, 2014, the answer sheets from 300 respondents were gathered, and the answer sheets from 295 respondents were analyzed except for the five ones that included uncertain answers. As a result, it's ascertained that cognitive dissonance was under the direct influence of post-surgery satisfaction with appearance, self-esteem, subjective norm and lookism.. Self-esteem, subjective norm and lookism had a direct impact on resurgery intention, and self-esteem and lookism affected resurgery intention both in direct and indirect ways through the medium of cognitive dissonance. The findings of the study are expected to provide useful information on the development of nursing intervention programs geared toward promoting physical and mental health.

Two experiments were conducted to examine the role of Kulja and morpheme in processing two-syllable Sino-Korean words. In Experiment 1, the effects of morphemic frequency were not significant at the initial and final positions of a word while Kulja frequency and Kulja-morpheme correspondence at both positions in a word had a significant impact on the processing of nonwords. Lexical decision times were longer for nonwords with high frequency Kulja and for nonwords with ambiguous Kulja-morpheme correspondence whose Kulja can go with many different morphemes. In Experiment 2 Kulja-morpheme correspondence was examined for words as well as nonwords. Lexical decisions were slower for stimuli with ambiguous Kulja-morpheme correspondence. The effect was more stable for nonwords, which replicated the result of Experiment 1. In sum, the results of this study suggest that words with ambiguous Kulja-morpheme correspondence activate many different morphemes and competition among these morphemic candidates slows down the lexical selection process. Kulja frequency, Kulja neighborhood, morphemic frequency, morphological neighborhood, and Kulja-morpheme correspondence in Korean word recognition were also discussed.

Enactivism is the most influential and groundbreaking approach among the various theories of embodied cognition. Despite of it's impact and relatively long history, however, Enactivism is still considered as a new and unfamiliar theory in the Korean academic society. Even though this might be partly due to the genuine depth and dramatic approach of Enactivism, it is also due to the disagreement of Korean translation of Enactivism. This paper reviews the philosophical and theoretical implications of Enactivism in the context of history and conceptual terrain, and discusses how the various tranlated Korean words of 'Enaction' - '발제(發製)' '구성(構成)', or '행위화(行爲化)'- embraced and interpreted the essence of philosophy and concept of 'Enaction' and 'Enactivism'. Furthermore, we offer several alternatives Korean translations of 'Enaction': '실행(實行)', 수행(遂行/修行), or 작동(作動). Through this discussion, we hope to provide an opportunity for Korean researchers and philosophers to direct their attention to Enactivism properly and to make a common ground for further development of Enactivism in Korea.

The business models has a great impact on the successful management of enterprises. Business environment has been shifting from industrial economy to knowledge-based economy. Enterprises go through numerous trials for successful management in the changing environment. Along with trial tests, research areas have been growing simultaneously. Although many researches have been conducted with regard to business models, it is very insufficient to systematically analyze the knowledge flow of research. Accordingly, successive researchers who want to study the business model may find it difficult to establish the orientation of future application research based on understanding the process of changing the knowledge structure that have accumulated so far. This study is intended to determine the current state of the business model research and to understand the process of knowledge structure changes in keywords that appear in 2,667 business model articles in the SCOPUS database. Identifying the knowledge structure has been completed through social network analysis, a methodology based on the 'relationship', and the changes in the knowledge structure were identified by classifying them into four different periods. The analysis showed that, first, the number of business model co-author increases over time with the need for academic diversity. Second, the 'innovation' keyword has the biggest center in the network, and over time, the lower-rank keyword which was in the former period has emerged as the top-rank keyword. Third, the cohesiveness group decreased from 12 before 2000 to 5 in 2015 and also the modularity decreased as well. Finally, examining characteristics of study area through a cognitive map showed that the relationships between domains increased gradually over time. The study has provided a systematic basis for understanding the current state of the business model research and the process of changing knowledge structure. In addition, considering that no research has ever systematically analyzed the knowledge structure accumulated by individual researches, it is considered as a significant study.

Objectives : Posttraumatic stress disorder(PTSD) has been primarily associated with emotional problems. Recently, however, the impact of PTSD on cognitive processes has interested a growing number of researchers. The current study is aimed at investigating the cognitive aspects of PTSD at both behavioral and neurological levels. Methods : We recruited individuals with PTSD who survived the Daegu subway explosion in 2003 as well as non-PTSD individuals as a control group. To evaluate the inhibitory processes and the neural mechanisms, we had these individuals perform the negative priming task simultaneously with functional MRI scanning. Results : Behaviorally, the negative priming effect was intact in the control group but was not evident in the PTSD group. In the imaging results, only the PTSD group showed the negative priming effect (i.e., increased activation of the negative priming condition as opposed to the neutral condition) in the dorsolateral prefrontal cortex, anterior cingulate cortex, and inferior temporal gyrus. The PTSD group also showed increased activity for the positive priming condition as opposed to the neutral condition in the claustrum. These results confirm and extend the previous findings that the integrity of the ACC is compromised in the trauma survivors due to disrupted white matter tract. Conclusions : The current results suggest that deteriorated performance of the PTSD group may be due to the functional problem as well as the structural abnormalities.

Online games are getting more popular among today's fun-seeking young students. The immersive power of these Internet-based games is so strong that many educators consider the integration of the games and learning to enhance learner motivation. However, the online games, which are primarily aiming g for 'fun', have cognitive, emotional, and social features and impacts that are different from the so-called 'educational' games. Therefore an interdisciplinary approach for better understanding of the online game in regard to its impact on learning and fun should be essential. In this study, the researcher will analyze relevant literature and theories from cognitive psychology, media and communication theory, and Ludology to grasp holistic understanding of online game phenomena, which will serve as basis of further research and development in this emerging area.

The purpose of this study is to explore how elementary mathematics teachers' adaptations of a reform-oriented mathematics curriculum material in the USA, Everyday Mathematics, influence elementary students' opportunities to learn mathematics. I illustrate how elementary mathematics teachers alter the curriculum material and how such alterations influence their students' opportunities to learn mathematics in their mathematics classrooms. Results suggest that the teachers with Everyday Mathematics did not appear to maintain the cognitive demand of mathematical tasks as appeared in the curriculum material, as set up by the teacher, and as enacted in the classrooms. The results also show that the teachers seemed to omit components including important tasks and suggestions in the curriculum material. As a consequence, the students did not have an opportunity to think and understand mathematics conceptually and meaningfully; they were exposed and encouraged to learn mathematics procedurally.
