Communication problems have been regarded as one of the biggest causes in trouble in many industries. This led to extensive research on communication as a part of human error analysis. The results of existing researches have revealed that maintaining a good quality of communication is essential to secure the safety of a large and complex process system. In this paper, we suggested a method to measure the quality of communication during off-normal situation in main control room of nuclear power plants. It evaluates the cosine similarity that is a measure of sentence similarity between two operators by finding the cosine of the angle between them. To check the applicability of the method to evaluate communication quality, we compared the result of communication quality analysis with the result of operation performance that was performed by operators under simulated environment.

Purpose: For effective crisis communication in the event of a disaster, we present policy measures by exploring what activities are required of companies on a daily basis. Method: Employees working for L company were surveyed about the disaster response department, disaster message, and perception of the company during the company's response to COVID-19, as well as the level of response behavior of the employee. Results: First, caller characteristics did not have a significant effect on behavioral changes of members. Second, while the disaster response message within the company had no effect on the members' normative behavior, it had a positive effect on the discretionary behavior. Third, caller characteristics and disaster response messages had a positive effect on public relations, and public relations appeared to mediate caller characteristics and members' discretionary behavior. Conclusion: Studies on disaster response messages are required in the disaster control tower inside the company in normal times, and activities to build a member-friendly corporate culture for strengthening public relations are needed.

모바일 단말기들이 기술적으로 발달하면서 모바일 앱 시장도 급속도로 성장하고 있다. 모바일 앱중에서도 메신저, 커뮤니케이션 앱들의 시장 점유율이 현저하게 높은 실정인데 반해 해당 앱들에 서 사용되는 비속어, 은어에 대한 제제는 전무하다. 현재 정부차원에서도 모바일 앱에서 행해지는 무분별한 언어폭력에 대한 조치를 취하려는 모습을 보인다는 것을 볼 때 메신저, 커뮤니케이션 모바일 앱에서 사용될 필터링 시스템은 선택이 아닌 필수라고 볼 수 있다. 따라서 이 논문에서는 안드로이드 플랫폼 기반 모바일 앱에서 SQLite를 활용한 앱의 내부 DB를 분석하여 비속어와 같은 특정 카테고리의 단어 사용빈도가 일정횟수 이상이 되면 사용자에게 경고 메시지를 보내주는 시스템을 제안한다.

Visual messages are fundamental elements for performing communication and indicate the signs which are delivered from the communicator to the communicatee via channels, Generally, we can classify visual messages into two groups; linguistic factors which are rational and deliver abstract concepts and unlinguistic factors which are mental and can be expressed concretely. Especially, web site with receivers' low attention and concentration need images which can attract their attention to visual messages. That is, web site is a medium which allows us to feel visual and emotional experiences. We can call it a standard of sign systems which are consisted of various styles of digital texts. The main purpose of this study lies in that we'll analyze how homepage introductory page as one of the forms of digital text conduces a meaning action to the receivers and that we'll apprehend the structures of images and different types of signs via a semiotic approach and analyze the underlying meaning of the messages. In order to survey the structures of images we'll look into the attitude toward perceiving messages by using semantic differential method which has been developed mostly by Osgood and analyze the visual images by adopting sign types of Fuss. As the signification is created by combining signs, it is significant that we'll analyze the meaning of sings between the transmitters and receivers from the semiotic viewpoint and study the signification systems.

In the digital media era, coded and non-coded communication are used to convey the message. As the computer interface has been adopted human communication methods, non-coded communication has bee used in the computer interface as well. The changes of message structure in the computer interface have an effect on shifting the way of user's message acceptance from passive to active. The recently developed computer user interfaces are for user to experience diverse visual effect The communication conveyed with this visual effects could be vague but user can conceive strong impact. This experience is understood not only through the visual experience from a monitor screen but also with a sense of tactile. The meaning of sensual and spectacle motion image could be ambiguous. However in the experience of using an interface, it plentifully expands the human sense by giving a visual experience on a whim. The sensually extemporaneous and splendid visual effect that has vague meaning has been very common happening in digital media environment.

This study is aimed at examining the degree in message recognitions with respect to the same global brand Ad. campaign intended for local consumers in Korea, China, and United-States, and applying the results to the forseeable message production of global Ad. campaigns. For this purpose, we conducted a survey by providing those consumers with Anycall Ads. of Samsung mobile phones, which were inserted in local printed advertisements. We concluded that the cultural and environmental differences of markets represent different degrees in message recognitions among these three countries. This result suggests that the localization based on local cultures and market situations is more important than the general standardization in the future global brand Ad. campaigns.

We have used SMS to exchange messages between mobile phones. Since the network evolved to the ALL-IP network, the next generation messaging service, RCS, has emerged to the market. Because SMS and RCS coexist, we need to inter-work the messages between SMS users and RCS users. This paper introduces a message inter-working framework(MIWF) that can inter-work SMS and RCS without changing end user's UX. It defines the call flows between the network equipment and MIWF. Also, it shows how MIWF converts messages between 3 protocols. Performance evaluation proves that MIWF does not add loads to the existing network.

In this paper, high-quality business-type communications(UC) capabilities of the communication activities overlap, waste, reducing rework process improvement provides for high efficiency. Messages sent via UC app development, FMC calling features, schedule management organization for the development and deployment DataBase UC server deployment, the search for the JSP implementation, XMPP is using the messaging system. IP-PBX running on the IP network, on the basis of UC applications in real life, improve utilization of the infrastructure necessary to provide services to the system design and implementation.

Consumers influence other consumers' brand choice behavior by delivering a variety of objective or subjective information on a particular product, which is called WOM (Word-Of-Mouth) activities. For WOM activities, WOM senders should choose messages to deliver to other consumers. We classify the contents of the messages a consumer chooses for WOM delivery into two categories: Subjective (positive or negative) evaluation and objective information on products. In our study, we regard WOM senders' activities as a choice behavior and introduce a choice model to study the relationship between the choice of different WOM information (WOM with positive or negative subjective evaluation and WOM with objective information) and its influencing factors (information sources and consumer characteristics) by developing two bivariate Probit models. In order to consider the mediating effects of WOM senders' product involvement, product attitude, and their characteristics (gender and age), we develop three second-level models for the propagation of positive evaluations, of negative evaluations, and of objective information on products in an hierarchical Bayesian modeling framework. Our empirical results show that WOM senders' information choice behavior differs according to the types of information sources. The effects of information sources on WOM activities differ according to the types of WOM messages (subjective evaluation (positive or negative) and objective information). Therefore, our study concludes that WOM activities can be partially managed with effective communication plans influencing on consumers' WOM message choice behavior. The empirical results provide some guidelines for consumers' propagation of information on products companies want.
