Let p be an odd prime and c be a fixed integer with (c, p) = 1. For each integer a with $1{\leq}a{\leq}p-1$, it is clear that there exists one and only one b with $0{\leq}b{\leq}p-1$ such that $ab{\equiv}c$ mod p. Let N(c, p) denote the number of all solutions of the congruence equation $ab{\equiv}c$ mod p for $1{\leq}a$, $b{{\leq}}p-1$ in which a and $\bar{b}$ are of opposite parity, where $\bar{b}$ is defined by the congruence equation $b{\bar{b}}{\equiv}1$ mod p. The main purpose of this paper is using the mean value theorem of Dirichlet L-functions and the properties of Gauss sums to study the computational problem of one kind mean value function related to $E(c,p)=N(c,p)-{\frac{1}{2}}{\phi}(p)$, and give its an exact computational formula.

As integrated management of scattered knowledge in the organization contributes to organizational performance, organizations are increasing their investment in knowledge management(KM) policies and technologies. For KM to be operated efficiently, the participation of employees performing knowledge-sharing activities is important. This study suggests how shared goal, value congruence, and task interdependence reduce the negative effects of relation and role conflict on the intention to share knowledge. We surveyed workers in organizations that have more than 50 employees and have KM policies, and 381 samples were used for hypothesis testing. As a result of hypothesis testing, we confirmed that a shared goal affects the intention to share knowledge through each of the factors of value congruence, relation conflict, and role conflict. In addition, we confirmed that value congruence and task interdependence moderated conflicts that negatively affected the intention to share knowledge. We identified the conditions that affect the knowledge-sharing activities of employees in terms of individual, organizational, and work structure. Therefore, the results contribute to the establishment of strategies for achieving the performance of the organization's KM.

Due to the expanding roles of corporations, the significance of Corporate Social Responsibility (CSR) has escalated, fostering continued efforts for organizations to integrate CSR into the context of recruitment. Additionally, demand for CSR authenticity is increasing. Damaged CSR authenticity can give rise to negative consequences, but research on the CSR authenticity is lacking, particularly within the realms of job search and recruitment. Consequently, this study aimed to investigate whether organizational attractiveness varies with CSR authenticity (high CSR authenticity, low CSR authenticity, and control conditions) through a scenario design. Additionally, the study examined the mediating effects of value congruence, as well as the moderating effect of moral identity in this relationship. Conducted among 300 undergraduate students, the results indicated that the organizational attractiveness was highest in the high CSR authenticity condition, followed by the control condition, and the lowest in the low CSR authenticity condition. However, the difference between the high CSR authenticity condition and the control condition was not statistically significant. PROCESS macro was employed to analyze the mediating model of value congruence. The results revealed that the mediating effect of value congruence was significant across all conditions. In sequence, examining the moderating effect and the moderated mediating effect of moral identity, it was found that these effects were significant in the high CSR authenticity condition in comparison to the other conditions. The findings of this study suggest the importance of considering CSR authenticity in the context of job search and recruitment and also, provides an insight into the mechanism through which CSR authenticity influences organizational attractiveness.

The Precise measurement of the knee's Congruence angle is required for diagnosis of patella dislocation. The purpose of this study is to consider the distortion diagram and usefulness about the test of the bilateral side and one side through the evaluating congruence angle from Merchant view of patellofemoral joint to central X-ray. We've evaluated the sulcus angle and Congruence angle following central X-ray's changes when we took Merchant view of patellofemoral joint aimed to right lower limb from human whole body phantom. The subject of the evaluation was classified as normal group and varus group, and the varus group has experimented with External rotation of legs as 15° and 30°. When normal groups result as 0, 7.5, 15 cm, it was measured as 17.25 ± 1.34°, 19.60 ± 1.41°, 20.55 ± 1.77° each. The gap between minimal and maximum angle was 3.3°, and the value was shown as getting bigger when it further away from the centeral X-ray. When Congruence angle in 15° varus group was 0, 7.5, 15 cm, it was each 16.45 ± 1.34°, 17.10 ± 0.99°, 17.80 ± 1.13°. And when Congruence angle in 30° varus group was 0, 7.5, 15 cm, it was measured each 18.35 ± 1.63°, 18.95 ± 1.06°, 19.60 ± 1.41°. The difference between minimum and maximum of angle in 15° varus group and 30° varus group was each 1.35° and 1.25°, the angles have shown as increasing the further away from the center. The patellofemoral joint showed that the congruence angle increases as the further away from Central X-ray, and also it is judged that is possible to change the congruence angle by a degree of varus knee. Thus, accurate measurement of the congruence angle is shown to advantage that methods for examining by split each side at two times than methods for examining both sides at a time. Therefore, it is expected to helpful on the diagnostic side of patella dislocation and subluxation.

The purpose of this study is to provide insights into live streaming consumer purchase intention by drawing on congruence between consumer and influencer factors and live shopping contents factors during the spread of COVID-19. We surveyed 348 individuals who have watched Fresh Hema's live streaming. SPSS and AMOS were used for data analysis. We determined that only actual congruity between influencer and consumer significantly influenced the consumer social experience. On the other hand, both the informativeness and entertainment value of live shopping contents positively impacted the consumer social experience. Additionally, social experience was significantly related to consumer co-experience and purchase intention. Moreover, the significant mediation effect of social experience was found amongst congruence between consumer and influencers, live shopping contents, co-experience, and purchase intention.

Purpose: This study was done to examine the effects of nurses' perception of servant leadership on leader effectiveness, satisfaction and promoting additional effort. The focus was the mediating effects of leader trust and value congruence. Methods: Data were collected from 361 RN-BSN students and nurses participating in nationally attended in-service training programs. Data were analyzed using descriptive statistics and structural analysis with SPSS 17.0 windows program and Amos 7.0. Results: Direct effects of nurses' perception of servant leadership were negative, but mediating effects of trust and value congruency were positively correlated with leader effectiveness, satisfaction and additional effort, that is servant leadership should be effective through mediating factors. Conclusion: The study results indicate that if the middle managers of nurses can build leader trust and value congruency between nurses through servant leadership, leader effectiveness, satisfaction and additional effort on the part of the nurses could result in a positive change in the long term.

Social enterprises are entities to pursue solving societal problems with maintaining commercial viability. In order for a social enterprise to achieve commercial viability, it must be able to provide products that consumers can satisfy, to make social enterprise trustable, and to establish a lasting relationship with customers. This study suggests that perception of value congruence, price fairness and service quality will affect customer performance such as trust, satisfaction and customer loyalty. And this structural relationship was confirmed through structural equation modelling. The empirical results show that customer trust and satisfaction can be improved when the value congruence is high and service quality is high. Meanwhile, the perception of price fairness has a negative effect on customer trust. However, considering the influence of price fairness on customer satisfaction, the total effect of price fairness on trust is not significant. This result implies that customers are less sensitive to social enterprise product prices than general companies. And customer satisfaction for the social enterprise is positively affecting trust and loyalty, and customer trust is also positively affecting customer loyalty. After the empirical analysis, this study suggests implications for social enterprises to improve customer performance and secure commercial viability.

Establishing a financial independence is essential for sustainable growth of social enterprises. In this vein, this study investigated the key factors that affect customer loyalty about the products or services provided by social enterprises. Commitment and trust in social enterprises were considered as main factors affecting customer loyalty. We also examined the effects of functional, hedonic and social value about the products or services of social enterprises on purchasing decision-making processes. The research model analysis was conducted on 204 consumers using social enterprises in Dong-gu, Daegu. The analysis of research model has shown that commitment and trust had a significant impact on customer loyalty about the product or service of those enterprises. Functional value did not have a significant effect on commitment, while it had a significant effect on trust. Hedonic value had a significant impact on both commitment and trust. Social value had a significant effect on commitment, but not on trust. Value congruence had a significant effect on both commitment and trust. Based on the our findings, it is expected that it would help establish operational and marketing strategies to improve competitiveness in products and services of social enterprises.

Purpose - As the role of salespersons in retail stores has expanded from selling products to sharing brand experiences with customers, the importance of research on the effects of salesperson-brand relationships has grown. The purpose of this research is to investigate the influences of salespersons' brand identification on conceptual fluency and customers' service and brand evaluations. It was supposed that salespersons' brand identification is affected by brand knowledge, which is a core dimension of internal branding. Research design, data, and methodology - The author developed a structural model in which salespersons' brand knowledge influences brand identification, hence customers' perception of salesperson-brand image congruence. And it is hypothesized that salesperson-brand image congruence influences conceptual fluency which affects customers' satisfaction and brand evaluation. Data were collected from five department stores in Seoul. Results - First, salespersons' brand knowledge was found to have a significant effect on brand identification. The more a salesperson knows about the affiliated brand, the higher her level of brand identification. Second, salespersons' brand identification influenced salesperson-brand image congruence. Third, salesperson-brand image congruence had a significant effect on brand conceptual fluency. Customers who perceive salesperson-brand image congruent are more likely to process information easily. Finally, conceptual fluency was found to be a significant determinant of store loyalty and brand value evaluation. Conclusions - The results of this study verify importance of salesperson's brand identification on customers' service and brand evaluations. To enhance salespersons' brand identification, retailers should emphasize the importance of internal branding and communication, especially by sharing brand vision, values, and identity with employees at customer contact points. Also, as brand conceptual fluency is a significant determinant of customer responses, retailers need to deliver consistent messages through various components of store environments, including salespersons' attitudes, appearances, and manners, as well as physical store design. With a deeper understanding of the effects of salesperson-brand relationship and brand conceptual fluency, retailers will be able to create more effective brand strategies to enhance their performances. Future studies should consider data from various retail types, such as discount stores, to generalize the findings.

Owing to COVID-19 pandemic and global recession, enterprises are facing more and more fierce competition. Under this situation, retaining as much as recruiting good employees has become a top priority for organization. However, post 90s, with very different characteristics from traditional workers, entered the labor market, and both employers and employees suffered from post-90's high turnover rate. Therefore, this study focuses on Chinese post-90s and examined the effects of work values they pursue (utilitarian orientation, interest congruence, long-term development, and innovativeness) on job satisfaction and turnover intention. In addition, the groups with less than or more than one year of service were compared and analyzed. A total of 267 Chinese workers born in the 90s participated in the survey. Our research findings show that utilitarian orientation affects both job satisfaction and turnover intention, but interest congruence only affects job satisfaction while innovation only affects turnover intention. And the moderating effect of tenure of service was partially verified. Various implications based on the result were discussed.
