Relay has been applied various communication environments due to its advantages of performance enhancement in communication systems. In this paper, we analyze the performance of a dual-hop communication system which uses one relay by considering asymmetric communication scenarios. The performance is based on bit error rate. Firstly, we compare the overall performance of dual-hop communication system under symmetric and asymmetric, and then analyze the performance depending on the resource allocation. Energy allocation and relay location are considered in the resource allocation. The performance of overall system for each energy allocation and relay location is analyzed. In addition, we analyze the performance of communication system when both energy and relay location are considered simultaneously. Based on the analyzed performance, we discuss the effect of resource allocation for symmetric and asymmetric environments.

The present study investigates how communication styles of leaders affect job performance and organizational citizenship behavior (OCB) through followers' positive psychological capital. While previous studies have examined the relationships among positive psychological capital, job performance, and organizational citizenship behavior (OCB), much less known about the effect of communication styles of leaders. This study divides leaders' communication patterns into dogmatic communication and sociable communication. To verify hypotheses of this study, we used data collected from the fashion companies. 191 surveys were distributed and 142 responses were used for the analysis. Empirical results show that sociable communication of leaders has positive impact on followers' positive psychological capital, job performance, and OCB, while dogmatic communication style didn' t have a significant impact on positive psychological capital, job performance, and OCB. In addition, job performance is influenced strongly by followers' positive psychological capital than OCB in sociable communication condition. The results of this study suggest implications for understanding the important role of communication styles on the relationship between followers' psychological mind-set and job behavior. Future studies are required to solve the problems on the inconsistent results between dogmatic communication and followers' job attitudes. The theoretical and managerial contributions and the limitations were discussed.

This Paper examines the effect of IT knowledge and IT communication on the operational performance of small firms. Small firms which could be defined firms with less than 50 people in total lags behind medium and large firms in computerization. In order to fill up the computerization gap resulted from size differences, Korean government has been promoting the 'Networking Small Firms' project since 2001. Survey data with 698 small firms in Korea, we could find that If knowledge and IT communication significantly contributed to the operational performance of small firms. Internal process performance is affected by individual IT knowledge, traditional communication, and e-mail communication. Customer performance is affected by above three factors, organizational IT knowledge and internet/EDI communication. Interestingly, financial performance is not affected by traditional communication but only IT knowledge and IT communication.

This paper investigates the performance of a hybrid single input multiple output radio frequency/free-space optics (SIMO-RF/FSO) communication system. Each SIMO-RF link is modeled as an independent and identically distributed (i.i.d.) Rayleigh distribution, while the FSO link follows a generalized $M{\acute{a}}laga$ (M) distribution. Considering the fixed gain amplify-and-forward (AF) relay and misalignment errors, novel expressions for the outage probability (OP), average bit error rate (ABER) and average capacity are derived. Numerical results show that atmospheric turbulence and misalignment errors can seriously impair the system performance, and the hybrid RF/FSO communication system using SIMO-RF links can greatly improve system performance. We also analyze system performance under different types of modulation schemes. Numerical results are verified by Monte Carlo simulations.

This study attempts to investigate the relations between the types of communication, the job satisfaction. and the nursing performance of the staff nurses. The subjects of this study were the 114 nurses working in general wards, intensive care units, and the emergency rooms of the general hospital in Kyongbuk province. They were asked to answer the questionnaires as regards the types of communication and job satisfaction, and their performance of nursing, and these were evaluated by the head nurses, and their direct seniors. The data were collected for 10 days from the September 17 to 26, 2002. According to the purpose of the study, descriptive analysis, ANOVA. Pearson correlation coefficient, and stepwise multiple regression were applied for the data analysis using SPSS 10.0. The results are as follows : 1. The types of communication of staff nurses showed that the upward communication was $3.12\pm0.56$. the downward communication was $3.56\pm0.42$. the horizontal communication was $2.98\pm0.44$. and the informal communication was $2.59\pm0.49$. It showed that the most frequent communication was the downward communication. 2. In terms of the job satisfaction, there was significant difference according to the length of the period working for one ward (F=5.95, p=0.003), 3. The performance of nursing was significantly different according to the age (F=23.52, p=0.000), the working duration as a nurses (F=21.9, p=0.000), the types of nursing unit (F=5.33, p=0.002), and the working duration in present nursing unit (F=15.87, p=0.000). 4. In terms of communication type, the job satisfaction was associated with quality of the upward communication (F=6.23, p=0.003), the downward communication (F=5.78, p=0.004), and the horizontal communication (F=11.73, p=0.000) There were no association between the types of communication and the performance of nursing. 5. There was a positive correlation between the communication and the job satisfaction. And the downward communication (r=0.398) showed the greatest correlation with the job satisfaction. There was no statistically significant correlation between the communication and the performance of nursing. And the upward communication (r=-0.058) showed a negative, though not significant correlation with performance of nursing. 5. There was a positive correlation between the communication and the job satisfaction. And the downward communication (r=0.398) showed the greatest correlation with the job satisfaction.

Recently, mobile communication systems are suffering from exponentially increasing data traffic. As a promising solution to the increase in data traffic, a coordinated multi-point transmission and reception (CoMP) scheme has been proposed. Although a great deal of research has been done on this new technology, the performance of mobile communication systems with CoMP has not been evaluated properly in a typical indoor environment. To address this, we have developed a system-level simulator and evaluated the performance of mobile communication systems with CoMP. Unlike previous works, we have used an actual antenna pattern in our simulator and link-level results are properly taken into account through link-level abstraction. By using a system-level simulator, we have evaluated the performance of mobile communication systems with CoMP in an indoor environment and found that unlike an outdoor cellular environment, CoMP may not improve the performance of overall mobile communication systems in an indoor environment.

This study tried to confirm the mediating effect of positive psychological capital on the relationship between the communication Competence of managers who are recognized as organizational members working in the company and the adaptive performance of the members. To this end, the research hypothesis established through the final 255 data was verified as follows using the SPSS 21.00 and AMOS 21.1 version statistical programs. First, the higher the manager's communication Competence, the higher the positive psychological capital of organizational members. Second, the higher the communication Competence of the manager, the higher the adaptive performance of the members. Third, as the positive psychological capital of organizational members improved, adaptation performance improved. Fourth, positive psychological capital showed a partial mediating effect between the manager's communication Competence and the member's adaptive performance. The results of this study empirically analyzed the relationship between manager's communication Competence and members' positive psychological capital assumption (+) on the improvement of organizational members' adaptive performance ability. This study has the meaning of the most important research in that it provides additional theoretical and practical implications in the face of insufficient research on factors affecting the adaptation performance of organizational members.
