This study aims to investigate the kinds of content and science communication included in the exhibits and the exhibition panels in order to suggest a direction of desirable educational development in the nuclear power information halls in Korea. The four local nuclear power information halls in Korea and the nuclear power science center in Japan are selected as the subject. The results of this study show that the 'conceptual' exhibits are a dominant topic among the four topics of contents, and the concept (CON) and interest (INT) are found as the most dominating component of science communication. Meanwhile, the nature of science (NOS), awareness (AW), enjoyment (ENJ), and opinion (OP) components are little exhibited. The findings of this study indicate that the nuclear power information halls can be more professional to enhance scientific literacy, as the informal education institutions, providing information of nuclear energy and radiation on various perspectives for visitors to make decisions by themselves and to improve their scientific attitudes and understanding of science communication. In addition, the limited science communication can be fully reinforced by docents or commentators. Further research needs to investigate the development of a specialized program to produce professional docents or commentators.

As a very important part in development of the protocol, verifications for developed protocol specification are complementary techniques that are used to increase the level of confidence in the system functions by their specifications. Using the informal method for specifying the protocol, some ambiguity may be contained therein. This indwelling ambiguity in control systems can cause the occurrence of accidents, especially in the case of safety-critical systems. To clear the vagueness contained in the designed protocol, we use the LTS (Labeled Transition System) model to design the protocol for railway signaling. And then, we verify the safety and the liveness properties formally through the model checking method. The modal ${\mu}$-calculus, which is an expressive method of temporal logic, has been applied to the model checking method. We verify the safety and liveness properties of Korean standard protocol for railway signaling systems. To perform automatic verification of the safety and liveness properties of the designed protocol, a communication verification tool is implemented. The developed tools are implemented by C++ language under Windows XP. It is expected to increase the safety and reliability of communication protocol for signaling systems by using the developed communication verification tool.

Collaboration between teacher librarians and parents is one of the very important elements for school library management in characteristics of learning communities and expanding its' administration. These partnerships are necessary to relieve stress and risk conditions and improve ego-resilience of students. This study analyzed cases of student guidance within the partnerships between teacher librarians and parents and then inquired into formal or informal communication channels for their partnerships through written interview with 10 teacher librarians. The results of analyses teacher librarians have appreciated the necessity of collaboration with parents, and they have experienced student guidance, career guidance, reader's advisory and balancing acts between classroom teachers and parents. It turns out that reading programs with parents are formal communication channel rather than institutional committee such as School Library Council and Parents' Library-Assisting Volunteers and Parent Association and Training in the school library are informal communication channels. The teacher librarians also provide periodic reading events and training for parents and they utilize the School Homepage and Educational Newsletters as the main ways of public relation. In order to promote students' ego-resilience through their collaboration, parents should involve in School Library Council as an essential way for formal communication. And parents' role in school library management should be expanded from offering helping hands to activities to read book, library instruction, assisting teacher librarians in the Library-Assisted Instruction and production of teaching mediums.

According to the computerization of railway signaling systems, the interface link between the signaling systems has been replaced by the digital communication channel. At the same time, the importance of the communication link is more pronounced than in the past. In this paper, new network-based protocol for Korean railway signaling has designed between CTC and SCADA system, and the overview of designed protocol is briefly represented. Using the informal method for specifying the communication protocol, a little ambiguity may be contained in the protocol. To clear the ambiguity contained in the designed protocol, we use LTS model to design the protocol for this interface link between CTC and SCADA, the LTS is an intermediate model for encoding the operational behavior of processes. And then, we verify automatically and formally the safety and the liveness properties through the model checking method. Especially, the modal ${\mu}$-calculus, which is a highly expressive method of temporal logic that has been applied to the model checking method. It will be expected to increase the safety, reliability and efficiency of maintenance of the signaling systems by using the designed protocol for railway signaling in Korea.

The $4^{th}$ industrial revolution refers to an era where machines capable of outperforming humans are created. In light of the 4th industrial revolution, university students are demanded problem solving abilities, critical thinking abilities, and problem discovering abilities as general and basic abilities. The need for changes in the university level communication education for engineering students remains imperative in this constantly changing social environment. The era where education is conducted only in classrooms is over. This paper discusses the need for diversified education such as the integration of online and offline education, the reinforcement of learning outside of the classroom as well as an education model that transcends formal and informal education such as games and activities that induce self-learning, both intentional and non-intentional learning, and the utilization of mass media and social networking systems. Through providing an education model that assesses and utilizes the data gained from the learning process provided above, this paper widens the perception of future education methods in the 4th industrial revolution.

This paper proposes a new noise suppression method using the Wavelet transform analysis. The noise suppressor using the Wavelet transform shows the more effective advantages in a babble noise than one using the short-time Fourier transform. We designed a new channel structure based on spectral subtraction of Wavelet transform coefficients and used the Wavelet mask pattern with more higher time resolution in high frequency. It showed a good adaptation capability for babble noise with a non-stationary property. To evaluate the performance of proposed noise canceller, the informal subjective listening tests (Mos tests) were performed in background noise environments (car noise, street noise, babble noise) of mobile communication. The proposed noise suppression algorithm showed about MOS 0.2 performance improvements than the suppression algorithm of EVRC in informal listening tests. The noise reduction by the proposed method was shown in spectrogram of speech signal.

The purpose of this research is to explore the phenomenon of the sharing, reuse, and citation of research software. These practices are playing an increasingly important role in scholarly communication. The researchers found that the citation and reuse of research software are currently uncommon or at least not reflected in the Data Citation Index (DCI). Such citation was observed, however, for the newer software in a number of prominent repositories. The repositories Comprehensive R Archive Network (CRAN) and Zenodo received the most formal software citations. The researchers observed both formal and informal forms of citation when researchers reused software. The latter form involves mentioning research software in passing in the main text of articles, while formal citations appear in the references section. In addition, our comparative analysis helps to explain the phenomenon of self-citation of research software.

With the spread of Internet personal broadcasting service, the number of personal broadcasting hosts (BJs: Broadcasting Jockeys) and viewers is increasing, and immediate communication between them is also actively taking place. This study examines whether the mechanism to suppress deviant behavior of BJ works effectively and how viewers interacting with BJs affect the intentions of deviant behaviors of BJs. Through the structural equation model, the effect of formal and informal sanctions of deterrence theory on BJs' intention of deviant broadcasting through their policy compliance attitude was investigated. The moderating effect of social pressure on the relationship between BJs' policy compliance attitude and their deviant broadcasting intention was confirmed. A total of 234 data were analyzed by surveying Africa TV BJs. As a result of the analysis, it was found that informal as well as formal sanctions increased the BJs' attitude toward policy compliance. However, it was confirmed that the social pressure perceived by BJs from Internet personal broadcasting viewers reduced the effect of policy compliance attitudes on reducing deviant broadcasting intentions.
