The present study examined the content and changes in leader role schemas associated with 'male' leaders, 'female' leaders, and 'good' leaders over the past 10 years in Korea. In addition, we analyzed how the gender of the respondents affects their perception of male leaders versus female leaders as a good leader. A total of 736 Korean adults residing in the Seoul metropolitan area participated in the survey at two different time points, one in 2007, and the other in 2017. The respondents were presented with a total of 90 behavior items driven from the literature and asked to choose the items that represent male leaders, female leaders, and good leaders, respectively. We found that the chosen behavior items for male leaders versus female leaders matched closely to the typical sex role of males (i.e., being agentic) versus females (i.e., being communal). By contrast, the chosen behavior items for good leaders reflected both the male-typed roles and the female-typed roles. We also found that the role schemas associated with male leaders as well as good leaders have changed over the 10 year period. Those schemas also differed between male versus female respondents. For female leaders, however, the role schemas were found to be stable over the 10 years. We also found that the good leader schemas are more specified and variable than are the male or the female schemas. Additionally, in the 2007 survey male characteristics overlapped with good leader characteristics to a greater degree than did female characteristics. This difference was no longer observed in the 2017 survey. The observed difference in the degree of overlap between male (versus female) characteristics with good leader characteristics was attributable to the perceptions of male respondents. We discuss implications of our findings and directions for future research.

Distance dynamics model is an excellent model for uncovering the community structure of a complex network. However, the model has poor robustness. To improve the robustness, we design an enhanced distance dynamics model based on Ego-Leader and propose a corresponding community detection algorithm, called E-Attractor. The main contributions of E-Attractor are as follows. First, to get rid of sensitive parameter ${\lambda}$, Ego-Leader is introduced into the distance dynamics model to determine the influence of an exclusive neighbor on the distance. Second, based on top-k Ego-Leader, we design an enhanced distance dynamics model. In contrast to the traditional model, enhanced model has better robustness for all networks. Extensive experiments show that E-Attractor has good performance relative to several state-of-the-art algorithms.

The study aims to verify the relationship between leaders' personality traits in leader - member exchange (LMX), and job performance. Hierarchical Regression Analysis was used to examines (a) how leaders' personality traits and LMX affect the influence of social capital on job performance and organizational citizenship behavior; (b) how perceived organization support (POS) can moderate the influences of LMX on social capital, in turn impacting job performance and OCB. Responses are employees in the service industry in Thailand, which consisted of 236 independent samples in 77 groups. Each group included at least one leader and 1-5 followers. The results show that there is a significant relationship between leader's personality traits, LMX and social capital. Leader with the higher level of conscientious, and agreeableness can always create good relations with their followers. The level of LMX are also related to social capital and both of these influence OCB and job performance. The moderating effect of perceived organizational support is also significant that POS can amplify the influence of LMX on social capital. Finally, the research findings show that perceived organizational support is one of the moderating factors in LMX exchanges. Followers perceived organizational support can amplify the influence of LMX on social capital.

This study aimed to find the influence with the moderating effects of brand credibility and the mediating effect of brand attitude from the relationship of Loss-Leader marketing factors, brand attitude and revisit intention to make management strategies and provide basic materials for the future restaurant industry. From the findings in this study, only limited sales strategy in the Loss-Leader marketing factors had a positive effect on revisit intention. Both Limited Sales and Price Discount Strategy in the Loss-Leader marketing factors had positive effects on the brand attitude, while Plus Pack strategy had a negative effect on the brand attitude. Also, the brand credibility has a significant moderating effect on the relationship between the Loss-Leader marketing factors and the brand attitude, and the brand attitude has a significant effect on revisit intention. The results indicated that these findings would be basic materials for Loss-Leader marketing factors and related studies in the future. In addition, this study suggests good implications in establishing and using the effective marketing management strategies in the restaurant industry.

The performance of transmission lines and its shielding design during a lightning phenomenon are quite essential in the maintenance of a reliable power supply to consumers. The leader progression model, as an advanced approach, has been recently developed to calculate the shielding failure rate (SFR) of transmission lines using geometrical data and physical behavior of upward and downward lightning leaders. However, such method is quite time consuming. In the present paper, an effective method that utilizes artificial neural networks (ANNs) to create a metamodel for calculating the SFR of a transmission line based on shielding angle and height is introduced. The results of investigations on a real case study reveal that, through proper selection of an ANN structure and good training, the ANN prediction is very close to the result of the detailed simulation, whereas the Processing time is by far lower than that of the detailed model.

In this article, the author studied the relationship between the Sovereign and the follower in Juyeok which contained some eliments, such as Eum-Yang, Soseong 8 gyae, Daeseong 64 gyae. In Juyeok, the 'Sovereign 5 hyo' (1) shows distinctiveness in basic characteristics whether they are Eum or Yang(high level classification), (2) shows characteristics of Soseong-gyae to which they belong(middle level classification), (3) shows different characteristics according to Daeseong-gyae's circumstances(low level classification). Five Yanghyo are regarded as male sovereign having masculinity, whereas five Eumhyo are female sovereign with femininity. Gungyae is the most 'sturdy type leader' who possesses dignity and has good judgement. Taegyae, the blessing type leader, holds affection and calmness within sturdiness. Rigyae is gorgeous and passionate 'enthusiastic type leader'. Jingyae, the pioneering leader, bravely starts ascending in Eum-dominant atmosphere. Songyae has the virtue of hesitancy and concession, known as the leader of humbleness. Gamgyae always stay low and calm, regarded as a leader of sense. Gangyae shoots up from the earth, meaning a leader of strong will. Gongyae, embracing type leader, is straight and square, though it tries to embrace everything. Daeseong-gyae(64gyae) is formed by Soseong-gyae piling another Soseong-gyae. The characteristics of Soseong 8gyae are embodied in two-level form, the top(inner gyae) and the bottom(outer gyae). Simultaneously, the whole characteristics of 대성괘 are embodied. The Sovereign should show his/her leadership based on the 'characteristics of Daeseong-gyae'. These characteristics are the contingency from 'contingency leadership'. In other words, they are preconditions which leaders ought to admit.

Purpose: The purpose of this descriptive study was to identify the impact of workplace bullying and LMX (Leader-Member Exchange) on turnover intention among nurses. Methods: The participants were 364 nurses from the Seoul metropolitan area who were attending a continuing education program. A structured questionnaire was used for data collection and data were analyzed using the SPSS/Window program. Hierarchical multiple regression analysis was performed to verify the effect of variables on turnover intention. Results: Higher workplace bullying was associated with higher turnover intention. Workplace bullying was negatively correlated with leader-member exchange. The most influential factors for turnover intention were LMX (${\beta}=-7.22$, p<.001), work load (${\beta}=2.96$, p=.003), and workplace bullying (${\beta}=2.64$, p=.009). These factors accounted for 28% of the variance in turnover intention. Conclusion: The study results indicate that there is need to develop strategies to prevent workplace bullying and cultivate a good relationship between nursing managers and nurses to lower nurses' turnover intention.
