본 연구에서는 협동학습을 적용한 공통과학 수업에서 학생의 의사소통 불안 수준을 고려한 소집단 구성의 효과와 의사소통 불안에 따른 차이를 조사하였다. 고등학교 세 학급 (112명)을 협동학습 두 반과 전통학습 한 반으로 무선 배치하였다. 협동학습 두 반의 학생들을 의사소통 불안 검사 점수에 기초한 의사소통 불안 수준에 따라서 이질 집단과 동질 집단으로 구성하였다. 11차시 동안 물질에 관한 수업 후, 학업 성취도, 자아존중감, 과학 학습 동기, 그리고 협동학습 과정에서의 의사소통 능력 부족에 대한 인식과 도움 받기에 대한 기대감을 조사하였다. 이원 변량 분석 결과 학업 성취도에서는 주효과나 상호작용 효과가 없었다. 그러나, 과학 학습 동기의 네 하위 범주 가운데 관련성과 만족감 점수에서 수업 처치의 주효과가 유의미하였다. 사후 비교에서 이질 집단의 점수가 통제 집단보다 유의미하게 높았다. 협동학습 과정에서의 도움 받기에 대한 기대감에 대해서는 이질 집단의 점수가 동질 집단보다 높았다. 의사소통 불안 상위 수준의 학생들은 하위 수준보다 자아존중감이 더 낮았고, 의사소통 능력에 대한 부족함을 많이 느꼈다.

Widely used around the world, smartphones contain many features and can store content such as contacts, photos, and videos. Information that can be leaked in proportion to the information that the smartphone can store has also been increased. In recent years, accidents such as personal information leakage have occurred frequently. Personal information leakage is happening in the Android environment, which accounts for more than half of the smartphone operating system market share. Analyzing malicious apps that leak information can tell you how to prevent information leakage. Malicious apps that leak information will send importantinformation to the hacker's (C & C) server, which will use network communication. Malicious apps that are emerging nowadays encrypt and transmit important information through SSL communication. In this case, it is difficult to knowwhat kind of information is exposed to network. Therefore, we suggest a method to analyze malicious apps when leak important information through SSL communication. In this paper, we identify the way malicious apps leak information. And we propose a method for analyzing information leaked by SSL communication. Data before encryption was confirmed in the device through SSL hooking and SSL Strip method.

In this study, we developed the environmental education program focused on the communication with the exhibits at the ecological museum applicable to the environmental education for gifted students. For this study, we chose 60 gifted students attending U Institute of Education for the gifted, and classified these students into two groups, then applied newly developed program to the 30 experimental group students, and applied general environmental education program to the 30 comparative group students. Below are the study results: First, the environmental education program focused on the communication with the exhibits at the ecological museum was much effective in increasing environmental sensitivity of gifted students as compared to the general environmental education program. Second, the environmental education program focused on the communication with the exhibits at the ecological museum was much more effective in increasing the willingness to environmental act for gifted students as compared to the general environmental education program Third, the satisfaction of the gifted students about the environmental education program focused on the communication with the exhibits at the ecological museum was higher than the general environmental education program.

As the power grids are integrated into one big umbrella called a "smart grid," communication protocol plays a key role in successful operations. The successful deployment of smart grid interoperability is a major hurdle that must be overcome. The micro grid, a small power system that distributes energy resource, is operated in diverse regions. Different vendors use different communication protocols in the operation of the micro grid. Recently, the IEC 61850 has been legislated to solve the interoperability problems in power utility automation. The present paper presents a micro grid system based on the IEC 61850 protocol. It consists of a micro grid monitoring system, a protocol converter that transforms serial data to IEC 61850 data, and distributed energy resource controllers for diverse DER nodes. A developed communication gateway can be deployed for DER controllers with serial links to exchange data with IEC 61850-based devices. The gateway can be extended to IEC 61850-based distribution automation systems, substation automation systems, or SCADA.

Purpose: This study was done to Identify the effects of a communication training program on communication skills and interpersonal relationships. Method: A communication training program was provided to student nurses who were selected as participants during a course of clinical practice. Of the students 23 were assigned to experimental group and 22 to the control group. The experimental part of the study was done with the experimental group during 6 week program course. The control group received only a communication theory course. Results: Communication and interpersonal relations scores on the post-test in the experimental group were significantly higher than in the control group. Conclusion: This program allowed nursing students to advance their communication skills during their clinical trials. These are skills which are necessary for nursing practice. The study demonstrated that a group training program that can provide students with practical support by improving the personal relationship.

Recently, Communication media have been developed for the underwater communication in underwater environments where the underwater communication failures occur frequently. Although the underwater communication by one medium is not stable due to the influence of the underwater environment, the use of various communication media can complement each other and so this makes the underwater communication more stable. For this reason, this paper proposes approaches to the design and implementation of integrated MAC for complementing individual unstable underwater communications. In addition this paper presents the comparison and analysis on each of the proposed approaches so to be able to provide guidelines to designers and implementers of integrated MAC.

Politics is defined as who gets what, when, and how. Communication is defined as the process, outcomes and effects of message transmission through a medium. Thus political communication in Asia, the most dynamic and uncertain region of the world, has been very dense, requiring rigorous scientific analysis and culturally sensitive reflection. Mass media brought about a revolution in political communication in the last century. In the 21st century, complex monitory devices from the state and international organizations and from the society and transnational groups have transformed the features of political communication. It has triggered another revolution in political communication. Illustrations are given focusing on Asia. A theoretical reflection from the angle of political science is attempted focusing on political communication medium and its effects. I compare no medium (face-to-face communication), mass media, and social media in relation to their effects.

일반적으로 현업에서 통합테스트 시나리오를 작성하는 개발자는 개발 단계의 이슈와 그들만의 요구사항을 테스트시나리오에 포함하는 경향이 있다. 즉 설계 단계에서 중요시 되던 사용자 요구 사항이나 우회 흐름과 같은 이슈들은 빠지기 쉽다. 이번 연구에서는 통합 테스트 시나리오 작성시 상태전이기법과 같은 테스트 설계 기법을 사용하여 개발자가 빠뜨리기 쉬운 설계 단계에서의 사용자 요구 사항과 같은 항목들이 고려되는 통합 테스트 시나리오를 도출하는 방법을 제시하였다. 이 방법을 활용한 결과 생각하지 못했던 테스트 케이스와 테스트 시나리오를 도출 할 수 있었고, 이로 인해 높은 만족도를 얻을 수 있었다.

Purpose: Nursing communication has become more important than ever before because quality of nursing services largely depends on the quality of communication in a very competitive health care environment. This article was to introduce ways to improve nursing communication using conversation analysis. Methods: This was a review study on conversation analysis, critically examining previous studies in nursing communication and interpersonal relationships. Results: This study provided theoretical backgrounds and basic assumptions of conversation analysis which was influenced by ethnomethodology, phenomenology, and sociolinguistic. In addition, the characteristics and analysis methods of conversation analysis were illustrated in detail. Lastly, how conversation analysis could help improve communication was shown, by examining researches using conversation analysis not only for ordinary conversations but also for extraordinary or difficult conversations such as conversations between patients with dementia and their professional nurses. Conclusion: Conversation analysis can help in improving nursing communication by providing various structures and patterns as well as prototypes of conversation, and by suggesting specific problems and problem-solving strategies in communication.
