Purpose: Communication skills are considered as one of the essential requirements in medical education, and the training often involves exercising medical interviews with standardized patients(SP) or role play. This study investigated the helpfulness of the communication skills training programs for students' performance on the clinical performance examination (CPX). Methods: Fourth-year students who have taken one of two communication skills programs(exercising communication skills with SP or elective communication skill course with role play) completed a questionnaire on their evaluation of the helpfulness of communication skills programs immediately after finishing the CPX. Then, the programs were objectively assessed by comparing all fourth-year students' CPX scores between program participants and non-participants. Results: About 70% of participants answered that the programs were helpful to perform clinical clerkship and CPX. However, there was no difference in either the total CPX score or 2 categorical scores(integrated clinical encounter, communication and interpersonal skill) between program participants and non-participants. Conclusion: Although the students felt that the communication skills programs were helpful to their clinical activities, this study failed to find objective evidence of any effect of the programs on the CPX results. Communication skills training should be continued during clinical clerkship to maintain or enhance the skills, and it is necessary to introduce more effective methods for precise evaluation of students' communication skills.

This study explores how Twitter users perceive their socio-communication attitudes as well as those who users follow. From the theoretical perspective of communication styles in interpersonal communication, this study focuses on the positions and roles of users and their partners in Twitter conversations by conducting a survey and a content analysis. The results demonstrate that the respondents tended to perceive their communication attitudes to be more passive on Twitter than in the real world. In addition, they tended to perceive that their most trusted followees were more likely to show dominant communication attitudes than they did. These results indicate that ordinary users are more likely to play a role as listeners than as speakers on Twitter while entrusting several trusted users with the role of a dominant communicator and that their perception of their own and their followees' communication styles tends to influence their actual behavior on Twitter.

The purpose of this study was to examine the relationships among parent-adolescent communication, adolescents self-esteem, social development, and home environment. Home environment includes sex, father's vocations, mother's employments, parents educational level, and religions. 275 adolescents (186 males and 89 females students) were selected from middle schools in Seoul. The results indicated that there was no significant difference in parent-adolescent communication, adolescents self-esteem and social development according to environmental factors, such as parents' age, educational level, and religions. Also adolescents self-esteem was highly correlated with parent-adolescent communication, especially with mother-adolescent open communication. Finally, adolescent development of sociality was highly correlated with parent-adolescent communication, but not significant relationship with mother-adolescent reverse-functional communication.

This study analyzed the relationship between mother-child communication and the self-concept of young children. The subjects were 93 three-, four-, and five-year-old kindergarten children and their mothers in the city of Chunju. The self-concept test, mother-child communication inventory for children and the mother-child communication questionnaire for mothers were used. The data were analyzed by T-test, General Linear Models analysis, Duncan's Multiple Range test, Paired T-test, and Pearson's correlation coefficient. The major findings were that (1) the children perceived mother-child communication more intensively than mothers, (2) the more positive communication the children perceived they had with their mothers, the higher their self-concept, (3) the self-concept of 5-year-olds was more highly correlated with perception about mother-child communication than the self-concept of the younger children, and (4) boys' self-concept was more highly correlated with perceived mother-child communication than girls'.

The objective of this study was to clarify the relations among mothers' self-esteem and facilitative communication, to children's self-esteem, and facilitative communication and then to inquire into how these relationships relatively contribute to children's self-esteem. Subjects were 206 elementary school children and their mothers in Anjang. Two types of instruments were used in this study. To measure the children's and mothers' self-esteem, SEI(Self-Esteem Inventory) was to used. To measure mothers' facilitative communication levels, "Mothers' Facilitative Communication Scales" was constructed by the researcher. The statistical procedures used for collected data analyses were correlation, one-way ANOVA, multiful regression. The findings are as following: 1. A significant static correlation was found between mothers' self-esteem and children's self-esteem. 2. Also, a significant static correlation was revealed between mothers' facilitative communication level and children's self-esteem. 3. The level of mothers' facilitative communication discloses a significant difference depending upon the mothers' self-esteem. 4. Mothers' level of facilitative communication affected children's self-esteem rather than the mothers' self-esteem.

In order to provide electricity to users economically and safely, distribution automation systems (DASs) monitor and operate components of distribution systems remotely through communication networks. The fiber optic communication network has been mainly installed for the DAS of Korea Electric Power Corporation (KEPCO) because of its huge bandwidth and dielectric noise immunity. However, the fiber optic communication network has some shortcomings that its installation cost and communication fee are expensive. This paper proposes a complex network where WLANs are combined with conventional fiber optic communication networks in order to expand DAS easily and inexpensively. A fixed wireless bridge communication unit (FWB-CU) for the proposed complex network is implemented using IEEE 802.11a WLAN technology. The proposed complex network is built actually to verify its feasibility experimentally as a DAS communication network.

We propose a high speed data communication method for motor drive systems with fast control cycle in order to collect state variables of motor control without degrading control performance. Ethernet is chosen for communication device, and multi-core DSP architecture is exploited for communication processing load distribution. The communication program including network protocol stack and motor control program are assigned to two separate cores, and data between two cores are exchanged using interrupt-based inter-process communication mechanism, which enables to achieve a high-speed communication performance without degrading the motor control performance. The performance of developed communication method is demonstrated by real experiments using TCP, UDP and Raw Socket protocols in an experimental setup consisting of TI's TMS320F28388D motor control card and MS Windows PC.

Satellite based communication is networks in which users in a wide area can access without wired-based ground infrastructure. In particular, the need is emerging due to the recent Ukraine-Russia war. Satellite network systems acquire data that is difficult to observe on Earth as well as communication networks and are also used for research and development, which allows additional data to be produced. However, due to the nature of communication networks existing in outer space, certain vulnerabilities are revealed, and attacks based on them can be exposed. In this paper, we analyze vulnerabilities that may arise due to the nature of satellite communication networks and describes current research, countermeasures, and future research directions.
