The purpose of this study was to investigate the interaction and effects of shame and parent-child communication on children and early adolescents' peer pressure. The subjects of this study were 359 children and early adolescents from 5th grade in elementary school to 2nd grade in middle school (187 boys, and 172 girls) in Daejeon city. The results of this research indicated that gender and age played a significant role on the effects of shame and parent-child communication on peer pressure. Open communication with mothers showed a positive relationship with boys' peer pressure, whereas open communication with father showed a negative relationship with boys' peer pressure. The interaction effects of shame and open-communication with fathers and mothers worked differently on peer pressure across gender and age. Interaction effects of shame and open communication with fathers and mothers were significant for boys, but not for girls. Interaction effect of shame and open communication with mothers was significant for children and adolescents.

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.

Social networking service(SNS) helps users manage, share and delivery a vast information as a communication tool. When users read crisis news in SNS, they communicate the information with others by considering not only their belief (i.e., cognitive risk perception) but also emotion (i.e., affective risk perception). However, few researches have been interested in the construct of communication behaviors of crisis in SNS. This study aimed to explore the role of risk perception (cognitive and affective risk perception) between crisis responsibility and communication behavior through dual processing theory. As a result of the empirical analysis, crisis responsibility had a positive effect on cognitive risk perception and affective risk perception. In addition, cognitive risk perception had no significant effect on communication behavior whereas affective risk perception had influence on communication behavior positively. Thus, our findings may predict that the affective risk perception through crisis responsibility is more potentially important to communication behavior such as sharing information rather than cognitive risk perception. The results give insightful ideas why marketer should reduce perceived emotion caused by risk to strengthen prospective SNS users understanding of communication behavior intention.

Purpose: The purpose of this study was to investigate the effect of SBAR communication program on nurse's perception about communication and attitudes toward patient safety. Methods: A single-group pre-post experimental study was conducted. A SBAR education program was provided to 167 nurses working in 9 general wards of a hospital in Seoul. A total of 153 questionnaires were included for the final analysis. Statistical analysis included analysis of variance, paired sample t-test, and Cochran-Mantel-Haenzel test. Results: After applying SBAR communication education, nurses perceived significant improvement in three of the five categories of communication between nurses and doctors; satisfaction (p=.001), accuracy (p=.001), and understanding (p=.002). The indicators of communication between nurses were also improved significantly in the order of accuracy (p=.001), satisfaction (p=.001), shift communication (p=.001), and openness (p=.016). The scores of nurse's attitudes toward patient safety demonstrated a significant increase in the five categories out of the six; perception of management (p=.001), working condition (p=.001), safety climate (p=.001), teamwork climate (p=.001), job satisfaction (p=.012). Conclusion: It is recommended that nurses and doctors use SBAR communication in their practice. Developing education programs and utilization methods is required for the effective establishment of SBAR communication.

Objective: The main purpose of this study was to examine the direct and indirect effects of parent-adolescent communication (through adolescent optimism) on adolescent conflict-coping styles. Methods: A total of 337 high school students participated in this study. They completed questionnaires about communications with their parents and their own optimism and conflict-coping styles. Data were analyzed using t-tests, correlations, and SEM. Results: Neither father- nor mother-adolescent communication had direct effects on adolescent conflict-coping styles. However, mother-adolescent communication had an indirect effect on conflict-coping styles, mediated by adolescent optimism. Adolescents who had open communication with mothers displayed higher levels of optimism, which led to more positive conflict-coping styles. In addition, multigroup analyses revealed that there were significant gender differences in direct and indirect effects. For boys, mother-adolescent communication directly influenced adolescent conflict-coping styles; however, father-adolescent communication did not directly or indirectly affect adolescent conflict-coping styles. For girls, neither father- nor mother-adolescent communication had direct effects on conflict-coping styles; only optimism had a significant effect on conflict-coping styles. Conclusion: The findings from this study suggest that communication with mothers and fathers have different effects on adolescents' conflict-coping styles. These findings have implications for future research and practice by emphasizing the importance of parent-adolescent communication and optimism in designing conflict-coping programs for adolescents.

This study suggests new perspective of interorganizational communication. The importance of communication quality is increasing because it affects performance of marketing channels. In perspective of information exchange, communication quality consists of accuracy, availability, timing, and credibility. In research model, the antecedents of communication quality adopt willingness of information sharing and capability of efficient communication. To examine effects of communication quality on channel performance, research model includes relation of communication quality and conflicts. For empirical test, relation of PC makers and their dealers is decided as a focal dyad. Findings indicate that overall hypotheses are supported except the relation of willingness of information sharing and communication quality.

Nano communication system technologies are future core technologies that facilitate the implementation of tiny wireless communication systems with sizes in the range of hundreds of nanometers to tens of micrometers, which cannot be implemented by current wireless communication system technologies. In particular, novel nano communication system technology, which is based on electrical and mechanical resonance characteristics of carbon nanotube(: CNT), does not simply miniaturize system modules, but suggests a new approach that changes system architectures. Therefore, this paper surveys the state of the art on CNT-based nano communication technologies in aspects of system implementation, and proposes important research issues for convergence of nano and communication technologies.

The purposes of this study were to explore what components of science communication and its level are contained in text panels of exhibitions in natural history museums and to propose its development direction of exhibition education in Korea. First, to find out the component and level of science communication contained in exhibition panels, the researcher team developed the analyzing tool which was called SEPAT (Science Exhibition Panel Analyzing Tool), then employed them to profile the component and level of science communication. Second, the researchers introduced the exemplary designed media of exhibitions to demonstrate how much science communication could be enhanced. The results were made as follows. First, the components of science communication was considerably weighted toward to 'concept' one. There were also a few 'awareness' and 'engagement', both of which were under 5% in each zone of exhibition and there was not 'NOSI' or 'opinion' embedded in the analyzed exhibitions. Second, the various type of designing exhibitions were found to promote or enhance the restrictedly represented components of science communication. It is suggestable for exhibitions to be designed through various type of 'media' to enhance science communication. Visitors are required to experience rich science communication to meet their educational needs, and exhibition developers in natural history museums and other museums are recommended to be professional in containing all components of science communication through various type of designing exhibitions.
