Current trends in the Korean construction industry, including the aging of the workforce, a lack of new Korean construction workers, and an inflow of unskilled foreign labor, have caused a range of problems, including quality deterioration, reduced productivity, insufficient understanding of the function and difficulties in communication, to name a few. Yet while countermeasures to these problems should be based on accurate and diverse fundamental data, including the current status of demand and supply of domestic and foreign construction workers, the perception of construction workers, studies on these questions have, thus far, been scarce. For these reasons, this study was conducted using a questionnaire for managers and workers on construction sites, to secure fundamental data relating to construction workers. The findings of the survey showed that it is urgent to prepare measures to educate, train and foster human resources, considering the aging of the construction workforce and the lack of an inflow of new construction workers.

The purpose of this paper was to examine various aspects of meaning negotiation process in online chatting. Korean college students were asked to engage in chatting on the Internet over the course of a semester-long period, and chatting transcripts were analyzed in terms of sources of communication breakdown, signals to indicate communication breakdown, strategies to overcome communication breakdown, and ways of closing meaning negotiation. According to the findings of the study, lack of background knowledge and incoherent string of sentences in text were two major barriers creating communication problems. Subjects were able to use signals to indicate their communication difficulties, and overcome them by using different strategies. In doing so, however, they were found to suffer a narrow range of signals and strategies, which showed their limited communicative ability in the management of interaction, and indicated a clear, strong need for an extension of discourse and strategic competences of Korean students for more effective and smoother transition of message in everyday interaction.

AI-powered robot news is drawing attention as artificial intelligence technology is fully spread in the news distribution field. Robot news still has many technical and ethical problems, but academic research on this is insufficient. This study analyzes the issue of robot writing in artificial intelligent based robot journalism industry using SWOT analysis. As a result, the advantages of big data processes, accurate information gathering, high efficiency and disadvantages such as lack of independent arguments and lack of evidence and opportunities for technical development, government support, academic development, and industrial applications, and threats such as uncritical acceptance and lack of talent have been found. This study suggests three future-oriented directions, such as human-machine collaboration, intelligent news, and chat-bot, through previous studies on the development direction of robot journalism-based article writing.

The ODR can be categorized into four distinctive types. First type is the asynchronous non-demeanour method. Second type is the asynchronous demeanour method. Third type is the synchronous demeanour method. Fourth type is the synchronous demeanour method. A typical example of the asynchronous and non-demeanour method is e-mail. The example of the synchronous and non-demeanour method is tele conference. The example of the asynchronous demeanour method is video recordings. The example of synchronous and demeanour method is video conference. The primary benefit of e-mail is to avoid the physical violence. But the costs of email is the lack of emotional aspects of disputants. The benefits of tele conference is ease of use, and reduces the negative aspects of face to face communication. but the costs are limitation of the exchange of written information. The benefits of video conference is the approximation of face to face communication by providing oral as well as visual communication. but it is insufficient to represent eye contact. The common limitations of ODR are as follows. First is the lack of human face. Second is the neutrality of arbitrators and mediators. Third is the authenticity of electronic document. Fourth is the digital divide across South and North and generations. Fifth is the cross-cultural communication. The development strategy of ODR is the training and education of arbitrators and mediators in the area of writing skill. Furthermore, it is necessary to supplement the weakness of email via diverse kinds of expressions to show emotions. Finally, it is necessary to train neutrals in the area of cross-cultural communication.

When individuals collaborated in virtual settings, communication is medicated through a variety of communication technologies, and is associated not only with communication effectiveness but also with socio-emotional interactions among group members. In this regards, scholars have examined how technology-mediated communication systems can be designed and used to facilitated communication interaction. However, the empirical results of the previous studies have revealed inconsistencies in the effects of communication media on users' behavioral or attitudinal responses, and on their viable effectiveness in organizations. Some studies claim that computer-mediated communication(CMC) is task-oriented but not suitable for emotional expression since it hinders close interpersonal interaction. On the other hand, some studies argue that individuals are able to develop interpersonal relationships more effectively in a CMC environment than in an FtF-environment. Due to the different perspectives, a theoretical gap exists, and it leads to the inconsistent research findings. The purpose of this paper is to combine the two different perspectives into single unified model, thereby providing a more realistic and comprehensive understanding about virtual collaboration. The present study here sought to answers the following questions with organizational communication perspective: What are the major components of virtual collaboration? What factors affect the performance of virtual collaboration? And what kind of managerial efforts should organization make in order to facilitate CMC media effectiveness in virtual collaboration? Although there is a certain belief that new media, namely technology-mediated communication support would create new opportunities, the problem of "how" or "why" has been an important question that is still not fully addressed. In this regards, we collectively reexamined previous literatures with major issues which are still controversial and integrated various theoretical activity within computer-mediated communication domain: task-oriented approach, socio-emotional approach, and evolutionary psychological approach. Our first contribution is to develop a framework for virtual collaboration by combining two different perspectives into a single unified model, providing a more realistic and comprehensive understanding. The second main contribution is the joint modeling of both social presence and cognitive effort, and the effects on two distinct but important communication outcomes(i.e., take performance and relational development). We tested the research hypotheses which were developed based on the various CMC theories using data gathered through a self-administered mail survey of 127 individuals of 69 virtual workgroups. The proposed model was supported, providing preliminary evidence that the tension between two opposite view should be integrated. The results show that the individual's psychological processes(social presence and cognitive effort) in a virtual environment significantly mediated the effect of CMC inputs (media richness, user adaptation, and shared contest) on the CMC outputs (task performance and relational development). Furthermore, this study shows that the lack of perceived media richness of CMC media can be complemented by user adaptation and shared context. Based on the results, we discuss how communication system should be designed and implemented so as to promote virtual interaction as well as how a virtual workgroup should be composed to complement the lack of media richness. A virtual collaboration using CMC media may create new value by overcoming the logistical constraints. On the other hand, it may also generate various managerial risks such as communicational depersonalization, process dissatisfaction, and low cohesion. Therefore, this study suggests that organization managers should carefully choose the CMC mediums and monitor individual member's cognitive and affective psychological processes during virtual collaboration to reduce potential risks in virtual collaboration.

Purpose: The Transtheoretical Model (TTM) is a theoretical construct explaining stages of health behavior change. The purpose of this study was to describe and analyze the stages of health behavior change and health related quality of life (HRQL), Method: A descriptive survey design was utilized, and, using a questionnaire, which included a series of 5 questions designed to assess stages of health behavior change and HRQL instrument, data were collected from 292 adults. Means, standard deviation, t-test, ANOVA, and SNK test were used to analyze the collected data. Results: Health risk behaviors were lack of stress management(44%), alcohol use (42.5%), poor nutrition (37%), smoking (36.3%), a lack of spirituality (28.8%), poor communication skills (21.9%), Lack of safety(21.6%), lack of fittness (20.1%), violent behavior(12.3%), and drug use(6.8%). There was a significant difference in HRQL according to stage of health behavior change (P=0.001). Conclusion: The results of the study identified the need for individualized nursing interventions that based on the stage of health behavior change. Nursing interventions that focus on the stage of health behavior change would be effective for health promotion for Koreans.

This study investigates the obstacles to implementing family-friendly policies and offering flexible work arrangements and provides policy directions. A survey was conducted of employers at 147 firms, resulting in 42-43 questionnaires being statistically analyzed. Frequencies, means and factor analysis were conducted by SPSSWIN 12.0. The findings are as follows: First, the main obstacle to implementing family-friendly policies was the burden of cost. Second, eight obstacle factors were extracted through factor analysis. They are; lack of replacement workers and concerns about equity issues, nonfamily-friendly culture, no guarantee of the effectiveness of programs, lack of information about the programs or polices, lack of communication and public relations, potential loss of productivity, administrative hassles, and structural obstacles. Third, there was a difference in implementing flexible work arrangements according to the factors of lack of replacement workers and concerns about equity issues and no guarantee of the effectiveness of programs. That is, the firms which didn't have these two obstacles tried to implement flexible work arrangements more than the others.

Password authentication schemes (PAS) are the most common mechanisms used to ensure secure communication in open networks. Mathematical-based cryptographic authentication schemes such as factorization and discrete logarithms have been proposed and provided strong security features, but they have the disadvantage of high computational and message transmission costs required to construct passwords. Fairuz et al. therefore argued for an improved cryptographic authentication scheme based on two difficult fixed issues related to session key consent using the smart card scheme. However, in this paper, we have made clear through security analysis that Fairuz et al.'s protocol has security holes for Privileged Insider Attack, Lack of Perfect Forward Secrecy, Lack of User Anonymity, DoS Attack, Off-line Password Guessing Attack.

The purpose of this study is to examine the perception of early childhood teachers on ecological art activities oriented to education for sustainable development. The research results are as follows. First, Early childhood teachers recognized the visual art of natural media, the pursuit of community values, and the participation and communication of social members as educational significance of ecological art activities. And difficulties in practicing ecological art were recognized as lack of educational environment, lack of ecological art teaching materials and specific examples, and teachers' lack of understanding of ecological art. Also, they recognized that ecological art activities foster core competencies in art experience area, such as nature-friendly communication skills, eco-friendly sensibility, and creative convergence skills. Second, regarding ecological art activities and sustainable development education, early childhood teachers considered the difficulties in practice as lack of awareness about sustainable development, lack of play meia and materials, lack of educational policies and support, and insufficient teacher training programs. Also, regarding the SDGs that can be practiced in ecological art activities, teachers were found to be highly aware of 'grow affordable and clean energy', 'improve clean water and sanitation', 'provide quality education' in the order. In the contents of education for sustainable development that can be practiced in ecological art activities, teachers are given the order of 'climate change response', 'clean energy', 'water and sanitation', 'quality education', 'health and well-being' and 'marine ecosystem'. was highly recognized. If an ecological art activity program is developed, the rate of responding that it will be used is high, so it is considered that the development of an ESD-oriented ecological art activity program is urgent.
