Digital Signage, a way of advertising or delivering information to viewers through digital displays, has expanded from being just an advertising channel in public places. Recently, it has become widely prevalent in restaurants and retail stores. Despite its wide expansion, digital signage is limited to specific usages and services and the devices it uses are also quite expensive. This study introduces a stick-type digital signage product that operates on Android OS, which addresses all the weaknesses of digital signage with much more reasonable pricing and stable operation. For stability, performance tests were executed on the hardware and applications. The results for hardware performance were extremely promising, as each scenario's maximum performance results, measured by Load Runner programs, reached target indexes. Also, as a result of the usability test, all participants, including non-digital signage system users (novices), were able to easily learn all the tasks. As a result of user satisfaction survey, positive responses were exhibited for ease of learning and usability (LEU), helpfulness and problem solving capabilities (HPSC), affective aspect and multimedia properties (AAMP), commands and minimal memory load (CMML), and control and efficiency (CE).

The purpose of this study aimed to find the effect of self-esteem and communication competence on clinical practice stress of the Korean nursing students. A total of 198 nursing students participated in this study. Data collection was conducted through the use of questionnaires constructed to include the Rosenberg Self-esteem Scale, Global Interpersonal Communication Competence, and the Clinical Competence Scale. As a result, self-esteem, communication competence, and clinical practice stress of the Korean nursing students were found to be(Self-esteem: $3.4{\pm}0.57$; Communication competence: $3.5{\pm}0.42$; Clinical practice stress: $3.6{\pm}0.58$). Also, the nursing students with female(85.4%), experience of simulation on clinical training(72.2%) were found to have significantly higher clinical practice stress. Moreover, there were significant correlations between self-esteem and undesirable role model(r=.156, p=.029), communication competence and clinical practice stress(r=-.329, p<.001). The factors affecting clinical practice stress were communication competence, gender, satisfaction of clinical practice, and experience of simulation on clinical training. They amounted to 27.8% in clinical practice stress. The results indicate a need to develop effective teaching methods and learning strategies to decrease clinical practice stress of the nursing students.

This study attempted to understand the characteristics of images of scientific experiments represented and consumed on YouTube, a representative of today's new media. In particular, this paper analyzes the case studies of YouTube's hydrogen peroxide decomposition experiment based on Baudrillard's theory of Simulation and Simulacra, which discusses the strong status of images and the ambiguity of the boundary between virtual and reality. A total of 14 YouTube videos related to hydrogen peroxide decomposition experiments were analyzed. In those videos, hydrogen peroxide decomposition experiments were typically conducted with several signs representing scientific experiments, but the most important sign in the videos were bubbles produced through experiments. For more public consumption of the content, the bubbles resulted from hydrogen peroxide decomposition reproduced in YouTube have been transformed into a more spectacular image as 'super-huge' and 'explosive' bubble. Considering the influence of new media that can be accessed by students anytime and anywhere, it is positive that science experiments in new media enhance students' intimacy and access to science. At the same time, however, it is also important to note the danger that the purpose of scientific experiments will be limited to only 'showing specular images', due to the nature of new media, which mainly deals with immediate and superficial images. Furthermore, this study argues that improving students' science media literacy is required to critically examine the science-related images represented in the new media based on understanding the characteristics and limitations of new media that deeply affect daily life.

The purpose of this review was to evaluate the effects of simulation-based education on clinical competence and confidence in nursing students and summarize the available evidence on the simulation-based intervention. A systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses: the PRISMA Statement was conducted. Studies published between 2005 and 2014 were reviewed using the following databases: RISS, KISS, and Google Scholar. The keywords used were nursing and either simulation or simulator. Selected studies were assessed for methodological quality using Quality Assessment Tool for Quantitative Studies. Seventeen studies were identified, including a total of 1,912 nursing students. All the 16 studies found simulation as a valid strategy on clinical competence and confidence in nursing education. This review provides updated evidence for simulation-based learning in nursing education. Further studies are needed to increase generalizability using randomized controlled trials, enough sample size, and longitudinal study design. In addition, valid measurements are needed to assess the main outcomes.

Due to media's characteristics, the methods of acting expression in stage differ from that in media. However, actors playing in either genre use the same internalization as the basis of their performance. The acting arising from actors' internalization is the same in stage acting and media acting. Nevertheless, media acting, by its genre characteristics, requires a more delicate and natural acting than that in stage acting. Such is because media acting shows a far more detailed and amplified performance that is shown on screen. The purpose of this research is to examine how to differentiate the expression characteristics of media acting from the expression methods of stage acting. Through this research, I attempt to present the expression methods of media acting that can show real life acting reflecting media's distinct characteristics, with the aim of benefiting students who practice media acting or professional actors. Diverse expression methods presented by training of media acting are expected to enable actors engaged in this field to produce excellent outcomes through acting training to successfully bring out a realistic and convincing performance through internalization. And together with the opportunity to build delicate and detailed acting styles that are required in media acting, acting styles that are differentiated from those in stage acting will also be discussed.

The purpose of this study was to confirm how the students have responded to their class according to STEB (science teaching efficacy belief) of secondary science teacher in astronomy classes. Middle school teachers in charge of 'The Solar System' and 'The Exosphere and Space Development' in the 2009 Revision Science Curriculum content system is selected as an object of study through random sampling method. Twenty-nine teachers were taken STEB questionnaire and asked to make it out. Twenty-seven completed a questionnaire of them is selected for this study. In addition, the top and bottom 5% selected through frequency analysis with the total score from the questionnaire were regarded as high and low STEB teachers. For data collection, this study was used methods such as semi-structured interviews, recording, participant observation. The results were as follows: First, science teachers of high STEB had a high accessibility about excellent professional knowledge and content of the curriculum relating to astronomical field. Second, high STEB teachers were prepared by the appropriate teaching strategies adequate to student-centered learning, whereas the low STEB teachers totally have had teacher-centered learning. Third, high STEB teachers had been provided as the idea that you can take advantage of a variety of instruments, as well as scientific knowledge through the Astronomical Society. Therefore, confidence in astronomical class and teaching strategies through content of the curriculum were very important variables to predict the STEB as well as astronomy-related class activities such as astronomical observations.
