  • Power plants maintenance data is to be sent to management server system via a communication network. In this case, reliable communication network is required. Transmission of the power plants maintenance data is used in the wired communication network or wireless communication network. PLC communication network is a kind of wired communication network. However PLC communication network is easily affected by noise. On the vulnerable areas in power line system, such as a mountain or rural areas, it is difficult to form a power line communication network. For a wireless communication, environment are also influenced factors in wireless communication. Harsh environmental factors are bring the communication characteristic degradation. In such areas it can be used a combination of two networks and in this way the complementary function can be achieved. Power plants are distributed in various regions across the country. The appropriate communication network is needed to maintain the power plant.This study investigated the effect of environment on the wired communication and wireless communication. It would examine a variable factor which is affect to the communication characteristic. We used PLC communication for wired communication network and ZigBee communication for wireless communication network. We investigated the characteristics of a single communication network and it raised the need for a complex communication technology to complement a single communication network.

  • Purpose: This study was done to explore the relationship in hospital nurses' of communication competence, communication types, and organizational commitment and to provide basic data for developing programs to improve internal communication and to promote nurses' commitment to their organizations. Methods: The participants included 316 nurses who worked in two general hospitals. The tools used for this study were the Global Interpersonal Communication Competence Scale (GICC) and Communication Satisfaction Questionnaire by Downs & Hazen (1981), revised by Seo (2002) and Mowday's tool (1979) for organizational commitment. Data were analyzed using SPSS/PC+12.0. Results: The mean score for communication competence was 3.46, and for organizational commitment, 3.19. For communication types, the mean score for formal communication was 3.18 and informal communication, 2.59. Communication competence had a positive relationship with formal communication (r=.32) and with informal communication (r=.16). Organizational commitment had a positive relationship with formal communication (r=.53), communication competence (r=.30), and informal communication (r=.27). Conclusion: The results indicate the necessity of developing programs to promote nurses' communication competence and also developing a system that will enrich active communication. Systematic and continuous training in communication is also highly recommended.

  • A blockchain is an underlying technology and basic infrastructure of the Bitcoin system. At present, blockchains and their applications are developing rapidly. However, the basic research of blockchain technology is still in the early stages. The efficiency and reliability of blockchain communication is one of the research problems that urgently need to be studied and addressed. Existing algorithms may be less feasible for blockchain-based communication because they only consider a single communication factor (node communication capability or node trust degree) and only focus on a single communication performance parameter(communication time or communication reliability). In this paper, to shorten the validation time of blockchain transactions and improve the reliability of blockchain-based communication, we first establish a multi-link concurrent communication model based on trust degree, and then we propose a novel integrated factor communication tree algorithm (IFT). This algorithm comprehensively considers the node communication link number and the node trust degree and selects several nodes with powerful communication capacity and high trust as the communication sources to improve the concurrency and communication efficiency. Simulation results indicate that the IFT algorithm outperforms existing algorithms. A blockchain communication routing scheme based on the IFT algorithm can increase communication efficiency by ensuring communication reliability.

The study sought to identify differences in demographic and eating out characteristics on perceived verbal and non-verbal communication. Research design and methodology: This study used a survey method to collect data. The questionnaire asked about previous experience with verbal and non-verbal communication with staff at a counter service restaurant. The study measured degrees of perceived verbal and non-verbal communication. In addition, the effect of verbal and non-verbal communication on satisfaction and revisit intention was measured. The principal results: Results of ANOVA showed significant differences in monthly income on verbal communication and monthly income and budget for dining out on verbal and non-verbal communication. Both verbal and non-verbal communication affected satisfaction and revisit intention significantly with slightly more power of verbal communication than non-verbal communication. Major conclusions: Results of this study suggest that consumers are affected by both verbal and non-verbal communication. Staff communication is critical to increasing consumer satisfaction and revisit intention; hence, training staff in effective communication is necessary.

  • Recently, V2X (vehicle-to-everyting) communication has established itself as an essential technology for cooperative autonomous driving. V2X communication currently includes DSRC (dedicated short range communication) communication technology, which is a WLAN (wireless local area network) based communication technology, and C-V2X (cellular-V2X) communication technology, which is a Cellular-based communication technology. Since these two communication methods are not compatible with each other, various studies and experiments are being conducted to select one of the two communication methods. In the case of C-V2X communication, there are LTE-V2X (long term evolutionV2X) communication technology, which is an initial version, and 5G-V2X communication technology, which is a next-generation version. 5G-V2X communication technology has been completed only until standardization, so LTE-V2X communication technology is mainly used. In this paper, we introduce trends related to various issues in V2X communication, including communication method decisions.

  • Design is one of diverse human communication activities. Development of technologies has led to execution of more active design communication functions, stirring social and cultural changes. The concept of design communication has become stronger by overcoming the limitations of verbal communication and expanding the methods of communication. These social changes are highlighted In the design of modern space. Even though communication in interior design activities is so important, detailed studies on communication of each entity are still very insufficient. Design communication refers to tools and activities for overall communications in the design process. In design activities, relevant communication is indispensible. Therefore, studies on practical communication methods are essential for accurate communication of content that has to be shared in the results or in the process of obtaining the results, rather than only focusing on the future techniques and functions of design. In other words, improving the efficiency of interior design communication requires establishing a communication relationship structure of each entity, which calls for proper expression methods depending on each entity. Therefore, this study is aimed at exploring efficient expression methods in line with the relationship structure of each entity in the interior design process.

  • The purposes of this research are to find out general trends of mother-adolescent communication and family stress to estimate the differences of communication patterns and family stress according to sociodemographic and communication variables and to analyze communication variables influencing on family stress. The samples were selected from high school students and their mothers and 342 couples were used in final analysis. Barnes & Olson(1982)'s parent-adolescent communication scale(PACI) and McCubbin(1981)'s family stress scale(FILE) were used to measure mother-adolescent communication pattern and family stress. The data were analyzed by frequency, percentage, mean, Chi-square, F-test Duncan-test, multiple regression, Pearson's r, and Chronbach's α. The result are summerized as follows: 1) Mothers highly perceived mother-adolescent open communication pattern but adolescents highly revealed mother-adolescent close communication pattern. The general trends of family stress showed that adolescents stress is higher than mothers. 2) Communication patterns showed significant differences in mother's age, adolescent's sex and communication variables in mother's education and conversation variables. Generally when mothers and adolescents communicated insufficiently and were not satisfied with communication patterns family stress was increased. 3) Family stress was significantly different in communication patterns. Form the regression analysis it was found that communication patterns are crucial to family stress. Especially open communication pattern between mothers and adolescents was the most important among the communication patterns for family stress was reduced.

Methods : The subjects were 336 college students majoring in health science at colleges located in Busan. The survey's questionnaire comprised 38 items, including 15 items for communication skills and 19 items for adjustment to college life. Results : In the gender-based comparison of communication skills and adjustment to college life, female students had better communication skills, with overall higher scores than male students for the understanding others and communication. In the age-based comparison of communication skills and adjustment to college life, students aged 21 to 22 showed the best communication skills, while students aged 18 to 20 exhibited the least communication skills. In terms of adjustment to college life, those aged 25 or older scored the highest, and those aged 21 to 22 scored the lowest. In the school-year-based comparison of communication skills and adjustment to college life, third- and first-year students showed the best and least communication skills, respectively. Overall, third- and fourth-year students were more adjusted at adjusting to college life than first- and second-year students. Third-year students also scored the highest in academic adjustment, whereas second-year students scored the lowest. In terms of relationships between the students' communication skills and their adjustment to college life, communication skills were positively correlated with the following subdomains: understanding of others, self-expression, and communication. Communication skills also showed a positive correlation with adjustment to the college environment, including personal-emotional adjustment. Conclusions : The present study found that communication skills did not significantly affect health science majors' adjustment to college life. However, given that communication skills are an essential factor for effective work performance and greater job satisfaction, it is recommended that colleges provide students with relevant education and experiences to help them enhance communication skills while in school.
