In development of monitoring and control systems, one of the most important points is to consider a redundancy so that the system can be operated normally although hardware faults are partly occurred. The purpose of this paper is to introduce a monitoring and control system with a redundancy function for I/O servers and communication networks. I/O servers composed with an active server and a standby server. Each server also has 3 communication ports, 2 ports of them were connected to field units and the other 1 port was connected to the other server. Field units have to be constructed to 2 communication ports connected I/O servers through communication lines. Also, server communication module was implemented for analyzing and handling fault elements. and was submodularized for linking easily with a monitoring and control module. An experiment with 2 servers and 2 field units was constructed to demonstrate its effectiveness.

Purpose: The purpose of this study was to determine whether nurses' nonverbal communication predict clients' service satisfaction and to investigate the mediating effects of their trustworthiness between nurses' nonverbal communication and clients' service satisfaction in psychiatric wards. Methods: A convenience sample of 206 psychiatric inpatients was obtained. Participants completed a demographic sheet and three study instruments. Results: There were statistically significant positive relationships between nurses' nonverbal communication, trustworthiness and clients' satisfaction. Trustworthiness was found to partially mediate the relationship between nonverbal communication and clients' satisfaction. Conclusion: Clients' perception of nurses' nonverbal communication, trustworthiness and satisfaction on the nursing services have a strong relationship. Findings contribute to a more comprehensive knowledge base regarding nursing services.

지식 정보화 사회에서는 미래를 살아가야 할 학생들에게 합리적으로 사고하고 이를 표현하는 수학적 의사소통 능력을 기르는 것이 필요하다. 2006개정 교육과정의 초등수학에서 수학적 의사소통과 관련하여 교수 학습방법으로 3가지의 내용을 구체적으로 제시하였다. 이에 본 연구에서는 개정교육과정의 교수 학습방법에서 제시한 3가지 사항을 중심으로 초등 수학과 교육과정에서 제시한 수학적 표현에 대한 조사와 개정교육과정 발표 이후인 2007년도부터 현재까지 수학적 의사소통 관련 주요 논문들에 나타난 내용의 특징을 조사 분석하여 앞으로 효과적인 수학적 의사소통지도에 활용하도록 하였다.

This study presents on the fire hazard analysis of communication cable in buildings. In order to analyze fire hazards for communication cable IEC 60332-1, UL 94 and cone calorimeter test are conducted. The number of cable used to experiment is 10 communication cable which are generally applied to data communication in buildings. The results show that 9 cables do meet the performance requirement of IEC 60332-1 and 8 cables are V-0 classification. IEC 60332-1 and UL 94 test are inadequate for fire hazard classification. The various parameters obtained by cone calorimeter test such as HRR, peak HRR, smoke production rate and so on. Also it is able to evaluate multiply fire hazard for communication cable with cone calorimeter test results.

This paper introduces a novel concept of 'Emotional Communication' for future smart phone. While traditional information based communication technologies focus on how to precisely transmit the content of message, emotional communication is intended to support and augment social relationship among people and to comfort the user to be happy. In this paper, we propose future communication services and core technologies which can estimate emotional desire of users and respond to the desire to be happy with connectedness and consolation from peoples. Firstly, we introduce emotion recognition techniques to estimate emotional desire of users. At second, the emotional responding services are categorized to four parts and the details are shown. Lastly we propose the process to implement emotional communication system and the main techniques to fulfill the system requirements for future smart-phone services.

최근 NFC(Near Field Communication) 기반의 통신 기능을 채용한 스마트기기 및 OS 등이 확산되면서, 기존의 RFID를 이용한 다양한 응용분야가 NFC로 대체되고 있다. Smart NFC 기술은 기존 서비스 및 기기와 쉽게 융 복합이 가능하며, 스마트폰을 활용한 결제 의료 인증 등 새로운 Network Communication 패러다임의 창출이 예상되고 있다. Smart NFC 보안 인증기기(Smart NFC Security Authenticator: SNSA)의 H/W와 S/W를 개발하고, 무선통신 시험 결과 허용기준값 이내를 만족하고, 토폴로지 영향의 실험 및 분석 결과, Daisy Chain 토폴로지가 Star 토폴로지에 비해 신호성능이 우수함을 보였다.

Purpose: The purpose of this study was to investigate the effect of parent-adolescent communication on academic stress and peer relationship perceived by high school students. Method: A total of 154 students were recruited from a high school in C city. Data were collected by means of self-reported questionnaires from September 1 to 18, 2015 and analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and multiple regression analysis with SPSS 20.0. Results: Positive correlations were found between father-adolescent communication and peer relationship(r=.35, p<.001), and between mother-adolescent communication and peer relationship(r=.22, p=.006). Negative correlations were found between father-adolescent communication and academic stress (r=-.23, p=.004), and between mother-adolescent communication and academic stress(r=-.17, p=.039). Conclusion: These results suggest that identifying the effects of father-adolescent communication and parent-adolescent communication programs on academic stress and peer relationship is required.

Purpose: The purpose of this study was to investigate effect of the SBAR-Collaborative Communication Program on nurses'communication skills and on collaboration between nurses and doctors. Methods: From March 11 to November 11, 2013, data were collected from 180 hospital nurses working in a university hospital in Gyeonggi province. Outcomes were measured at three time intervals; before, three and six months after the program was completed. Results: After participating in this program, there was a significant increase in nurses'communication skills but not in collaboration between nurses and doctors. None of the participants' general categories influenced nurses'communication skills at pre-test, but age, education level, total years of working and work department significantly influenced scores at 3 and 6 months. Work department was the only category for which there was a significant difference in collaboration between nurses and doctors at pre-test, and education level and work department were related to significant improvement at 6 months. Conclusion: Findings indicate that this program can improve communication skills for nurses and also, collaboration between nurses and doctors, especially for nurses under 25 years of age. Thus nursing and hospital managers should provide SBAR-Collaborative Communication Programs to new nurses in their job training.

This paper reviews research on family communication in Korea. The 51 literatures which had been published till 1988 are used to review. The review includes brief summaries of literatures in methodological issues and research findings classified into five major domains ; theoretical understanding, communication in family relationship, relation to human development, family communication in home management, and the use of family communication in family therapy. Some of the major conclusions may be summarized as follows: 1) Family communication research has short history since it begun in 1973. 2) Research method used in almost the survey research. 3) It is difficult to generalize the research findings because of the short of research and the unexquisiteness of methodology, but is is possible somewhat to understand family communication in Korea.
