Information behavior is an important area of research in library and information science (LIS) that has evolved over the last 75 years. The aim of this study is to investigate the recent trends of information behavior research by providing insights into emerging topical areas within information behavior. To conduct this study, the bibliographic data from Scopus was used, and the trends of information behavior were traced by using variations of key terms used in information behavior research, such as "information behavior", "information seeking behavior", and "information needs." In addition, the trends were analyzed in terms of content words in the title, highly cited journal articles, disciplinary categories, and author keywords. Information behavior research has its roots in LIS, but the findings of the study reveal that information behavior has expanded to other disciplines by intersecting a variety of topical areas. In particular, this study showed that information behavior in the health/medicine domain has become a predominant emerging topical area of research. In order to enhance our understanding of complex human behavior, future research should focus more on interdisciplinary aspects by measuring the scope of information behavior.

The purpose of this study was to examine the effects of a script intervention based on multimedia on the verbal and behavioral self-advocacy skill of elementary school students with disabilities. A multiple probe baseline design across subjects had been used with 4 students with intellectual disabilities. The results showed all participants showed significant increase of verbal and behavioral self-advocacy performance in asking for help, expressing one's opinions, and coping with violations, and the effects were maintained. The intervention was more effective for verbal self-advocacy than behavioral. Some suggestions for future study are discussed.

This study aimed to make an empirical investigation into the effects of supervisor's ethical leadership in a public library on its members' organization citizenship behaviors. While a number of studies on the associations between ethical leadership and organization citizenship behavior were carried out in other areas, such studies have been very few in the area of library. In this context, this study hypothesized and verified the relationship between ethical leadership and organization citizenship behaviors in the area of library. As a result of empirical analysis, it was found that ethical leadership has positive (+) effects on conscientiousness, courtesy, and sportsmanship among the components of organization citizenship behaviors. This demonstrates the importance of ethical leadership, and suggests the necessity for further extensive studies that investigate the effects of ethical leadership on members' organizational commitment and job satisfaction, through the input of diverse variables.

Among many other factors associated with anger expressions and problem behaviors, the effect of temperament has not been much investigated in adolescents. Thus, the purpose of this study was to investigate the relationship between temperament and problem behaviors in adolescents, and whether dysfunctional anger expressions mediated this relation. A total of 360 students in either middle or high school participated but only data from 354 surveys were analyzed. We found that temperament was associated with dysfunctional anger expressions and problem behaviors, and the relationship between temperament and problem behaviors was mediated by dysfunctional anger expressions. Temperament adaptability was shown to be negatively related with dysfunctional anger expressions and problem behaviors, while temperament approach was shown to be positively related with anger-out expression and externalized problem behaviors. This study suggests that appropriate intervention of anger related issues in adolescents considering their temperament should is needed.

Many of the theoretical studies have considered herd behavior as a source of the volatility in financial markets, but there have been few empirical studies on the dynamic herding due to the technical difficulty of detecting herd behavior with time-series data. In this context, this paper proposes a new method for measuring time-varying herd behavior based on QR-GARCH model. Using daily data of KOSPI stocks, this paper provides some empirical evidence for strong and volatile herding among traders of stocks of medium firms, and shows that time-varying herd behavior in traders of some stocks has persistent autocorrelation.

The purpose of this study is to identify the relationship between the employees' perception of organizational justice and their prosocial behaviors, focusing on the moderating effect of employees' individualism and collectivism. The survey has been conducted for 200 participants working in Korean companies. The results show that the perception of organizational justice is positively related with their prosocial behaviors. Also, employees' individualism and collectivism is significantly related with their prosocial behaviors. Specifically, individuals who are more collectivistic or less individualistic performed more prosocial behaviors than those who are less collectivistic or more individualistic. Finally, employees' individualism/collectivism has moderated the relationship between the perception of organizational justice and prosocial behaviors. When employees have strong sense of collectivism, they performed prosocial behaviors consistently regardless of the perception of organizational justice. That is, even though they perceive organizational justice as low, they perform prosocial behaviors in some degree. However, when employees have strong sense of individualism, their prosocial behaviors have been significantly determined by the perception of organizational justice. That is, when they perceive organizational justice as low, they rarely performed prosocial behaviors. But, as they perceive more organizational justice, their prosocial behaviors have been dramatically increased. The implication of those results and future research questions have been discussed.

In order to explore the impact of gender in the effects of age, temperament, and parenting on preschoolers' psychosocial problems, 339 preschoolers, 3-5 year old, were assessed using parent report measures of externalizing and internalizing behavior problems, temperament, and parenting. The results of ANOVA and hierarchical regression analyses are as follows. First, the main effects of age and gender for externalizing problems and the interaction effect of age and gender for internalizing problems were significant. Second, the important predictors of preschoolers' internalizing and externalizing problems were different by gender. In boys, Novelty Seeking(NS), Harm Avoidance(HA), and hostile parenting significantly predicted both problems. In girls, NS, HA, and warm parenting significantly predicted both problems. In addition, girls were more strongly influenced by parenting whereas boys were more influenced by their temperaments. The results of this study highlight some important suggestions for prevention strategies for preschoolers' behavioral problems. The implications and limitations of this study were further discussed.

The present study was conducted to test the mediating effects of work engagement in the relationship between issue leadership and innovative behavior. Specifically, the purpose of this study was to empirically test the impact of issue leadership on employees' innovative behavior, and to investigate the mediating effect of work engagement in the relationship between issue leadership and innovative behavior. The data was collected from 218 employees who are currently working at large hotels located in Seoul and Jeju. The results of this study show that issue leadership is positively associated with work engagement and innovative behavior, and that issue leadership is a crucial factor to facilitate employees' positive attitudes toward voluntary change-oriented behavior. In addition, work engagement partially mediated the relationship between issue leadership and innovative behavior. Finally, theoretical and practical implications of the study results have been discussed along with limitations and future direction of the study.
