Objective : This study aimed to investigate the level of friendship perceived by hospital staffs in korean medicine hospitals in Gwangju and relationship between friendship and organizational effectiveness. Method : The subject were 134 hospital staffs in 5 different hospitals in Gwangju. The questionnaire used in this study contained 44 questions about workplace friendship (15 questions), organizational effectiveness (16 questions), social demographic characteristics (8 questions) and others (5 questions). Results : Young woman in their 20s and 30s were major participants (69person, 52.7%), nursing and administrative department(72person, 55%) were dominant division, the person those who have less than 1 year current workplace career(69person, 52.7%) were major group in this study. Participants responded about barriers of friendship at workplace were lack of opportunities for formal or informal meeting and lack of hospital's interest and supporting about human relations among employees at workplace. Both friendship level with superior and friendship level with subordinate were lower than friendship level with colleague. (p=.000) Participants who have higher workplace friendship level, were also higher level at job satisfaction, organizational commitment and lower level at turnover intention, job stress. Especially friendship level with superior had biggest relationship with variables of organizational effectiveness. Conclusion : Participants showed close relationship with friendship degree and organizational effectiveness. We suggest that the CEOs of korean medicine hospital would make their effort to improve friendship level of workers for the rise of organizational effectiveness.

With the development of smart grid technologies, a user can use the secure and reliable power services in smart gird environments. However, the users are not secure against various potential attacks because the smart gird services are provided through the public channel. Therefore, a secure and lightweight authentication and key agreement scheme has become a very important security issue in smart grid in order to guarantee user's privacy. In 2019, Zhang et al. proposed a lightweight authentication scheme for smart gird communications. In this paper, we demonstrate that Zhang et al.'s scheme is vulnerable to impersonation and session key disclosure attacks, and then we propose a secure authentication and key agreement scheme for smart grid environments without tamper-resistant devices. Moreover, we perform the informal security and the BAN logic analysis to prove that our scheme is secure various attacks and provides secure mutual authentication, respectively. We also perform the performance analysis compared with related schemes. Therefore, the proposed scheme is efficiently applicable to practical smart gird environments.

In this study, pre-service science teachers' web-based reflective journals were analyzed. During four weeks teaching practicum, they were guided to post at least two reflective journals in a week on the Web bulletin board system. Finally, 307 web-based reflective journals written by 23 pre-service teachers were selected, and the domain and the level of reflective thinking were analyzed. As a result, pre-service science teachers' reflective journals were mostly related with teaching science, i.e., preparing and reflecting their own instruction, and the frequencies of these domains increased with the process of teaching practicum. Reflective journals about school administrative system, informal teaching practice, student guidance, and personal feeling were also included. The level of reflective thinking of 179 journals about teaching science were analyzed further. There were 53 (29.6%) journals including reflective thinking, but the higher level of reflection (professional reflection and critical reflection) was rare. The perceptions of pre-service science teachers on web-based reflective journal writing were also surveyed.

The 2015 revised mathematics curriculum encourages students to use graphs in newspapers and the Internet as materials when teaching graphs, and to experience a series of statistical problem-solving processes that collect, classify, organize, graph and interpret data. The graphs that the students learn through traditional textbooks were a single type of graphs. In particular, the graphs of the 5th and 6th grade groups were only increased in numbers, but the basic concepts were repeated in the 3rd and 4th grades. Fortunately, from the 2009 revision curriculum, it is possible to select the graph suitable for the situation while comparing the characteristics of some graphs. In most cases, the graphs used in the real world are presented in the form of a compounded infographics. The purpose of this study is to analyze and analyze the manifestations of information processing competence elements emphasized in the 2015 revised curriculum through the statistical project class using the informal graphic in the fifth grade of elementary school. And we suggested a concrete class plan.

The relevance of secondary school algebra focused on paper and pencil manipulation has been reconsidered along with the expansion of universal education and the development of ICT such as computer or calculators. This study was designed to investigate the issues and trends of the recent algebra so as to provide implementations for algebra curriculum in Korea. The focus of algebra education has being shifted from paper pencil manipulation to algebraic thinking. The early algebra or informal algebra is one of the important traits of revolution, and the role of ICT is integrated in newly developed curricula. In Korea, algebra education has been retaining the traditional line even though the national curriculum documents allows ICT for instruction. The reasons of these discrepancies were analyzed and the tasks for the new curriculum in accordance with the current trends were suggested in this paper.

Innovations of SMEs are critical for economic growth and creating employment. Collaborative innovations between SMEs and Public Research Institutes has been increasingly important to overcome limitation of SMEs innovation capability. Many studies on the collaborative innovation have been focused on the issues of absorptive capacity, project administration, and relationships of actors. This study, however, focus on attribute of project leader and partnership. Data on 149 R&D collaborative projects between SMEs and a Public Research Institute were collected. Empirical results show that project leaders' capabilities and partnerships including informal collaborative relationship unification, administrative unification, and contractual unification appear to affect performances both economical and technical. It also shows that the previous experience of R&D collaboration appear to effect the relationship between project leaders' capabilities, contractual unification, and administrative unification and technical performances.

A chatbot is an important area of mobile service, which understands informal data of a user as a conversational form and provides a customized service information for user. However, there is still a lack of a service way to fully understand the user's natural language typed query dialogue. Therefore, in this paper, we extract meaningful words, such a region, a food category, and a restaurant name from user's dialogue sentences for recommending a restaurant. and by comparing the extracted words against the contents of the knowledge database that is built from the hashtag for recommending a restaurant in SNS, and provides user target information having statistically much the word-similarity. In order to evaluate the performance of the restaurant recommendation chatbot system implemented in this paper, we measured the accessibility of various user query information by constructing a web-based mobile environment. As a results by comparing a previous similar system, our chabot is reduced by 37.2% and 73.3% with respect to the touch-count and the cutaway-count respectively.

The Center for Nanotechnology in Society at Arizona State University (CNS-ASU) is a Nano-scale Science and Engineering Center (NSEC) funded by the US National Science Foundation (NSF). It implements an agenda of "real-time technology assessment" (RTTA) in pursuit of a strategic vision of the "anticipatory governance" of nanotechnologies. To achieve this vision, CNS-ASU unifies research programs not only across several universities but also across three critical, component activities: foresight (of plausible future scenarios), integration (of social science and humanities research with nano-scale science and engineering), and engagement (of publics in deliberations). CNS-ASU also performs educational and training activities as well as public outreach and informal science education. This paper elaborates the Center's strategic vision of anticipatory governance and its component activities, especially in the context of extending the concerns of societal dimensions research beyond the traditional risk paradigm.
