Purpose: The purpose of this study was to develop Situation, Background, Assessment, Recommendations(SBAR) program and to test the effects of the program on communication clarity, clinical competence, and self-efficacy for clinical nurses in cancer hospitals. Methods: This study applied a nonequivalent control group non-synchronized design. There were 28 participants in the intervention group and 27 in the control group. SBAR program consisted of 4 parts and applied for 6 weeks in the intervention group. Data were analyzed with ${\chi}^2$ test, Fisher's exact test, t-test and ANCOVA using the SPSS program. Results: Communication clarity, clinical competence and self efficacy were significantly increased in the intervention group compared to those in the control group. Conclusion: These results suggest that SBAR program may improve communication clarity, clinical competence and self-efficacy for clinical nurses in cancer hospitals. Therefore, it is required to actively take advantage of this program to improve communication clarity among medical staffs, clinical competence, and self-efficacy in clinical nursing practices.

Purpose: This study was conducted to examine the effects of simulation-based education on communication skill and clinical competence in maternity nursing practicum. Methods: This study used a non-equivalent control pretest-posttest design. The simulation-based education in maternity nursing practicum consisted of two clinical situation scenarios pertaining to patients with normal and high-risk deliveries. The control group consisted of 35 students in 2010 and the experimental group consisted of 35 students in 2009. The experimental group was given the simulation-based education using a high-fidelity patient simulator over 3 sessions, whereas the control group was given a conventional pre-clinical practice orientation before maternity nursing clinical practicum. Data were collected using a questionnaire, which included questions to assess communication skill and clinical competence. Data were analyzed using SPSS/WIN 18.0. Results: Members of the experimental group, who received the simulation-based education, showed significantly higher communication skill and clinical competence scores than the control group (t=-2.39, p = .020; t=-2.71, p = .009). Conclusion: The simulation-based education in maternity nursing practicum is effective in promoting communication skill and clinical competence. With application of diverse clinical situation scenarios, it is recommended to develop and apply simulation-based education using a high-fidelity simulator in the area of maternity nursing.

This study identifies communication patterns of groups using Instant Messenger for their group decision-making, and examines how these patterns are associated with creative solutions to problems. Our research suggests that certain communication behavior of groups, when appropriately organized, can be of help in enhancing creative production of outcomes. A qualitative study was conducted on communication patterns based on an analysis of text-based electronic conversation protocols. Specifically this research tried to overcome existing studies on electronic groups by focusing on interactive process of communication among participants. The major study conclusions are: (1) Satisfation of group decision-making may depend on the process or sequence of discussion among group members with Instant Messenger. That is, proper interactive responses and appropriate control of the discussion process are essential to obtain a high level of performance. (2) It is important to ]mike discuss rules based on meta-cognitive and interactive protocols in the early stage. Explicit rules relating to internal group processes as well as communication medium use are even more important to groups with Instant Messenger than face-to-face groups.

The purpose of this study is to investigate elementary students' communication in process of applying mathematical modeling. For this study, 22 fifth graders in an elementary school were observed by applying mathematical modeling process (presentation of problem ${\rightarrow}$ model inducement activity ${\rightarrow}$ model exploration activity ${\rightarrow}$ model application activity). And the level of their communication with their activity sheets and outputs, observation records and interviews were also analyzed. Additionally, by analyzing the activity cases of and , this study researched that what is a positive influence on students' communication skills. Whereas showed significant advance in the level of communication, who communicated actively on speaking area but not on every areas showed insensible changes. To improve communication abilities, cognitive tension and debate situation are needed. This means, mathematical education should continuously provide students with mathematical communication learning, and a class which contains mathematical communication experiences (such as mathematical modeling) will be needed.

In this paper, the design of a channel filter and its group-delay-and-amplitude equalizer is carried out for the Ka-band satellite transponder subsystem. The 8th order dual-mode filter is employed for high selectivity around the band-edges with an elliptic-integral function response and has an in-line configuration. The 2-pole, reflection-type, group-delay equalizer is designed and manufactured to reduce the group-delay and amplitude variation, which can be large for such a high order filter. It is noted that in both the filter and equalizer, adopting the dual-mode coupling mechanism leads to less mass and volume. Through measurement, the performance of the realized group-delay-equalized filter is shown to meet the equipment requirements and to be appropriate for the satellite input multiplexer.

최근 스마트 기기의 보급화로 Wi-Fi, LTE 등을 이용한 무선인터넷 사용률이 대폭 증가한 반면 유선인터넷의 비율은 감소하고 있는 추세이다. 이렇듯 장소에 구애받지 않고 무선인터넷에 접속하여 사람과 사람뿐만이 아니라 사람과 사물간의 통신, 사물과 사물간의 통신인 사물인터넷의 범위가 점점 다양해지고 있는 추세이다. 사물인터넷(Internet Of Thing)의 빠른 확산과 함께 사물인터넷 보안 위협에 대한 우려도 크게 늘고 있다. 본 논문에서는 사물인터넷 환경에서 그룹 통신을 위한 키 분배와 관리에 대한 새로운 기법을 제안한다. 제안 기법은 키를 분배하지 않고 그룹에 속한 사물이 자신의 비밀 정보와 공개 값을 가지고 계산한 그룹 키를 사용하여 그룹 멤버 사이에 안전한 그룹 통신이 가능하게 된다.

무선통신 시스템의 표준으로 되어있는 TETRA(Trans-European Trunked RADIO) 시스템의 그룹 서비스와 소그룹 서비스의 안전한 통신을 위한 모델을 제안한다. 먼저, TETRA 시스템의 통신 서비스를 위해 인가된 구성원만이 데이터를 수신할 수 있어야하므로 안전한 브로드캐스팅 기술이 필요하다. 따라서, 본 논문에서 제안한 모델을 적용하면 소그룹 내부적으로 안전한 TETRA 통신 서비스를 위해 소그룹 키를 공유하고 그룹 내에서 이루어지는 TETRA 그룹통신 서비스를 위해 인가된 모든 구성원들이 안전하게 그룹 키를 공유하게 된다. 또한, TETRA 시스템의 통신서비스에서 그룹통신을 행함과 동시에 소그룹통신이 가능하게 된다.

Responsiveness and initiative between infant and mother from toy centered play situation at 6, 7 months of age and infant's social communication skills at 12 months were studied in a sample of 62 infant-mother pairs. Through the video analysis, infants were grouped into simple react group, cooperated group, and active initiative group. In the between groups, we analyzed whether mother's initiative act styles and response styles were different, and whether their social communication skills were different when they tested at 12 months. The results showed that mother's initiative styles were not different but mother's response styles were significantly different with infant groups. Further result showed that cooperated group gained higher score than active initiative group in the total score of Eary Social Communication Skills scales at 12 months of age. The results suggested that mother's responsive behaviors were more important than initiative behaviors for the infant's positive interaction, and the difference of these behaviors would lead to a gap of early social communication abilities.
