As the media changes, communication patterns in modern society have been changed as well. This change in the media environment has also transformed the required literacy and it is time to accept this new literacy in Korean language education. At this point, this paper inspected the perception of media literacy classes of 73 teachers currently in the field of Korean language education. The results show that most teachers are aware of the media literacy which has changed socially, and show strong agreement that this changed literacy should be applied in the field of Korean language education. However, today's media literacy education is passive. Although teachers generally understand the dynamic features of newly emerging digital media, it remains as a tool in class. The teachers pointed out that device problems such as device environment and the spread of media are one of the many reasons for such passive usage. However, the more fundamental problem is that the new communication environment has not been reflected in the curriculum actively. Teachers thought that media literacy has a close relationship with Korean proficiency. Also, they saw that this kind of media literacy will be required for Korean learners in the future with more importance. Based on the results of the study, this paper argues that Korean language education needs to accept and reflect the changes of media in the curriculum.

In high education, knowledge is the very important resource and output. Knowledge management is the art of creating additional value from academic knowledge assets. The e-community is the network community, newly created by information communication technology, and the critical place that share and transfer people's the various knowledge and thinking and the effective space that can apply knowledge management. If we construct a convenient and useful e-community in our university, we will be able to increase the student's intellectual needs, and create new knowledge. Web-portal will promote the activity of e-community providing easy to access and personalized web circumstance. The emergence of Internet and Web access to all university services will force institutions to rethik everything. We should reconfigure our academic environment in order to adapt information technology and educational change, and must do change management based on their structure and culture.

Many students prefer to study abroad to increase their chances of having a better future. While studying abroad they may encounter difficulties such as adapting to the culture of the country they are studying in. Chinese students coming to Korea are no exception to this, and when they are studying abroad, the new environment they are in may cause them hardships which may impact on their social life and even their academic performance. In order to develop their careers, they face many difficulties and challenges. Cultural differences they experience may change their attitudes, thoughts, and values. This research focuses on international students who are not yet certain about their future plans. In order to grasp levels of daily life satisfaction, ease of communication, and future planning orientation, this study conducted a survey of Chinese students who study in Korea. The empirical analysis showed that students with high level of life satisfaction have a tendency to enter graduate school. However, communication has no relation to future planning orientation.

This study begins with a review of commonly discussed dimensions of public risk perception that may influence public opinion toward risks. Factors that have been revealed by the literature to have substantial impact on risk perception, such as demographic background, trust, and media environment, are also discussed. Meanwhile, we evaluate two well-known research models in the realm of risk analysis: 1) the psychometric paradigm, and 2) the social amplification of risk framework (SARF). Based on a literature review, this study suggests that, besides the psychological and social approach, models of risk perception and risk communication research should shift to a more comprehensive one by considering the interrelations between laypeople and the environment. This study proposes a research model from the perspective of social cognitive theory (SCT) as a potential framework for future studies: 1) in the societal environment, individuals' risk perception and information seeking behavior, which is determined by risk perception will be influenced by trust in regulators and interpersonal trust; 2) in the media environment, individuals' risk perception and information seeking behavior will be influenced by individuals' perceived information characteristics. Knowledge about risk accumulated through information seeking will change risk perception in a longitudinal process.

Currently, research on network functions virtualization focuses on using microservices in cloud environments. Previous studies primarily focused on communication between nodes in physical infrastructure. Until now, there is no sufficient research on group key management in virtual environments. The service is composed of microservices that change dynamically according to the virtual service. There are dependencies for microservices on changing the group membership of the service. There is also a high possibility that various security threats, such as data leakage, communication surveillance, and privacy exposure, may occur in interactive communication with microservices. In this study, we propose an ID-based group key exchange (idGKE) mechanism between microservices as one group. idGKE defines the microservices' schemes: group key gen, join group, leave group, and multiple group join. We experiment in a real environment to evaluate the performance of the proposed mechanism. The proposed mechanism ensures an essential requirement for group key management such as secrecy, sustainability, and performance, improving virtual environment security.

Objective: This study describes the change of operator performance in drastic change of illumination level, and proposes an alternative method to cope with it. Background: The control standard of illumination for nuclear power plants(NPPs) is based on the set of limit criteria for maintaining a specific illumination level. However, there is a possibility to cause human errors according to the psychological and physiological influences to operators in the situation of drastic change of illumination such as SBO(Station Black Out), so a basic study is necessary to review the current approach. Method: We assessed the visual fatigue, subjective work load and task performance according to the three illumination situations(Normal Illumination, Emergency Illumination, and Drastic Change of Illumination). Result: Research finding shows that there are not significant differences in task performance between normal illumination (1,000lx level) and emergency illumination (100lx level), only if beyond the dark adaptation limit. However, subjective work load on mental demand and visual fatigue show a potential challenge to visual performance in drastic change of illumination. Conclusion/Application: Several trials can complement this challenge in NPPs by applying 3-way communication, enhancing readability of procedures, and managing the visual factors affecting the operators' performance through a Visual Environment Management Program including visual health aspects, etc.
