Although individual-level factors (e.g., attitudes, personality) have long been associated with day-to-day attendance decisions, increasingly researchers have recognized "the social nature of attendance dynamics and their susceptibility to social control (Johns, 2008)." Implications of this social approach for research would be to focus attention on the causes and effects of absence culture (i.e., absence-related perceptions, beliefs, values), and the effects of absence culture on individual and group attendance within social units. Construction projects typically require workers to work in teams or crews on highly interdependent projects, and, thus, are particularly relevant contexts to study absence culture. In this paper we apply a system dynamics (SD) model to study absence culture by utilizing the advantages of SD in capturing a feedback process and state changes. We were particularly interested in: (a) the awareness of social norms within construction crews that pertained to attendance, (b) the interplay between formal attendance rules (policy) and these social norms, and (c) how these sources of influence affected the decision-making process of construction crew members. We expect that the results of this work will help construction organizations evaluate (or re-consider) the effects of their attendance control policies (e.g., timing, strength, and frequency) within a social context. Moreover, our findings suggest that the key to reducing excessive absences might be to invest time in influencing absence culture directly rather than imposing frequent and strict regulations - which, in turn, may inadvertently fortify a culture that works against the organization's interests.

The main objective of this paper is to investigate the factors affecting organizational citizenship behavior of hospital employees, and based on the investigation, to suggest some implications for effective human resources management of hospitals. For this purpose, physical therapists were selected as the subject of the research. Using their individual characteristics, job characteristics, professionalism and group cohesiveness as the variables affecting organizational citizenship behavior, an empirical model was constructed and tested. A survey was conducted through structured and self-administered questionnaire for the physical therapists working at hospitals of Busan-Kyongnam area, and data from 240 therapists were utilized in the final analysis. Major results of the empirical analysis are as follows: First, perception on professionalism and the degree of organizational citizenship behavior were higher for male, older, relatively more-educated and higher-grade employees. It is necessary to develope some measures to educate and motivate the employees who are in lower state of professionalism and organizational citizenship behavior. Second, among the individual characteristics, need for growth was found to have significant, positive influence on professionalism and group cohesiveness, but no direct effect on organizational citizenship behavior. On the other hand, extroversion had direct, positive effect on organizational citizenship behavior, as well as on professionalism and group cohesiveness. This result suggests that personnel selection and personality education should be conducted carefully. Third, job characteristics appeared to have very large, positive effect on professionalism, but not directly on organizational citizenship behavior. Fourth, professionalism was found to have very large, positive influence on group cohesiveness and direct, positive effect on organizational citizenship behavior. This implies that enhancing professionalism of physical therapists can strengthen organizational citizenship behavior in hospitals, and hence top management should actively support the programs for job re-design, skill education and quality improvement to enhance professionalism of their employees. Fifth and last, as an intervening factor, group cohesiveness appeared to have the largest, direct, positive effect on organizational citizenship behavior. It is, therefore, important for top management to improve group cohesiveness by exploring ways toward greater harmony and solidarity among the members of physical therapy department.

This research aims to explore the relationships between academic writing ability and 'thinking styles' (capable of representing individual differences and diversity) in engineering freshmen in Korea, and to draw educational implications for the development of instructional strategies. (Academic) Writing is not just about conveying an idea or content, it is also about the representation of writer's self. In this perspective, there has been some research conducted on writing (process) and personality. However, to date, little attention has been paid to writing ability of engineering students and its relationships with thinking styles. This study was conducted with 127 engineering freshmen as well as 67 non-engineering freshmen at H University, and students' writing ability as well as their thinking styles have been measured before and after writing class for 15 weeks. Our findings show that firstly, there was a significant difference of writing ability by majors. Second, there were significant differences in freshmen's thinking styles by majors. Third, there was significant differences of writing ability according to thinking styles. Freshmen's internal, legislative and hierarchical styles scored significantly higher in writing ability than the others. And as for the engineering freshmen, internal, external and global styles scored significantly higher in writing ability than the others. Finally, there was a weak but significant relationship between writing ability and thinking styles(hierarchical & internal). These findings are expected to provide an explanation for the development of instructional strategies of writing (related) courses in engineering school.

This paper is to analyze how Walt Whitman developed the theme and structure of Leaves of Grass with his ideal of democratic vistas. Whitman established his identity as an inspired poet, having faith in the divinity of man based on transcendental belief. After being awakened to the transcendental truth, he practiced his own common world view--his democratic vistas. Whitman searched for the unity with nature and identified his self with "common man and his nation." The poetry expresses "cosmological and national ideology" dedicated to the creation of an ideal nation united in eternal freedom and peace. By portraying common cosmic and national theme in terms of his individual personality, he brought various paradoxical and controversial ideas into one thing, namely "democracy", fusing diversity into unity. As in the symbol of the grass, there is a unity in variety reflected by democracy in a cosmological and political compound. With the form of free verse, he could express his liberal unrestrained and mystical thoughts of democracy. This new form has been associated with the poet's strong consciousness of the need for modernization in his country. He willingly assumed "the role of prophet and public voice for American democrat" with the rolling catalogues and I-persona which formed a sense of the common man and common things of America. Whitman pioneered a democrat literature with simple and dynamic tone and style. He successively pursued the democratic vistas in his Leaves of Grass.

Online games have become the focus of entertainment and multimedia industries as the developments in computer technologies are accelerated and the use of the Internet diffuses broadly. In spite of such growth of online games, academic discussions regarding online games are relatively limited. This research examines several factors that affect player loyalty to online games. In this research, the loyalty is classified into two categories, the behavioral loyalty measured by the intensity, volume, and frequency of use, and the cognitive loyalty measured by the degree of immersion in online games. In this research, an integrated model to explain and predict player loyalty to online games in proposed. Two studies are conducted to test to research model. Throughout analyzing 334 respondents, the first study finds that the impulsive personality of individual players significantly affects both behavioral loyalty and cognitive loyalty. Additionally, it finds that, whereas the behavioral loyalty is influenced by the convenience of online game playing, the cognitive loyalty is influenced by the motive of game playing and the playfulness of games. The second study finds that the behavioral loyalty differs across demographic differences of players (age and occupation), preferred online games of players, and online game playing locations, but the cognitive loyalty differs across only age differences of players. This research has opened a forum for social awareness about the online game culture, provided information to guide online game producers to prepare customer-oriented online games, and created a foundation for academic research on online game industry.

버드휘스텔(Birdwhistell)은 말이 전하는 의미는 전체커뮤니케이션의 35%이하에 불과하고 나머지 65% 이상은 비언어적 형태로 전달되며 인간은 전적으로 언어에 의해 의사소통을 하는 존재가 아니라 모든 감각을 사용하는 감각적 존재라고 설명하고 있다. 인간의 커뮤니케이션은 언어 외에 표정, 몸 동작 등을 통해 보다 더 구체적인 의미 전달이 가능하며, 특히 얼굴표정은 개인의 성격, 관심, 반응에 대한 정보 및 감정의 상태를 전달해주는 다면적 메시지체계로 강력한 커뮤니케이션 도구라고 할 수 있다. 다양한 표현기법과 표현의 정도, 특성에 따라 달라질 수 있지만 표정이 갖는 상징적 기호는 일반화 된 특성을 가지고 있다. 스토리상의 등장인물로서 내면세계와 심리적 상태가 행동이나 표정으로 자연스럽게 노출되고 읽어낼 수 있는 감정표현에서 애니메이션 캐릭터는 생명력을 갖는다.

Intelligent tutoring system enables users to effectively learn by utilizing various artificial intelligence techniques. For instance, it can recommend a proper curriculum or learning method to individual users based on their learning history. To do this effectively, user's characteristics need to be analyzed and classified based on various aspects such as interest, learning ability, and personality. Even though data labeled by the characteristics are required for more accurate classification, it is not easy to acquire enough amount of labeled data due to the labeling cost. On the other hand, unlabeled data should not need labeling process to make a large number of unlabeled data be collected and utilized. In this paper, we propose a semi-supervised learning method based on feedback variational auto-encoder(FVAE), which uses both labeled data and unlabeled data. FVAE is a variation of variational auto-encoder(VAE), where a multi-layer perceptron is added for giving feedback. Using unlabeled data, we train FVAE and fetch the encoder of FVAE. And then, we extract features from labeled data by using the encoder and train classifiers with the extracted features. In the experiments, we proved that FVAE-based semi-supervised learning was superior to VAE-based method in terms with accuracy and F1 score.
