We are exposed to video content and numerous information from digital signage such as convenience stores, coffee shops, restaurants, and elevators on buses and subways 365 days. However, so far, studies have focused solely on the technical effectiveness of digital signage or the consumer experience aspect of digital signage, and little has been done on the impact of teaser advertising on the intent of viewing. Through this study, we hope that the digital signage of convenience stores will develop into a differentiated digital signage area that provides diverse video content experiences to consumers and viewers and allows them to communicate, suggesting a direction as a research that shows that digital content (video) is now recognized as a product in an environment where demand for non-face-to-face and digital content is gradually increasing in 2020 after the global COVID 19.

This study examined how the memory effect and the brand attitude effect differ according to the interaction (high / low) and the involvement (high / low) of digital signage. The two-way MANOVA analysis using SPSS 18 was used for the empirical analysis. The results of this study are as follows: First, GRM is recalled if the level of interactivity and inffence of digital signage is low, but if both conditions are high, ARM recalls. Second, if the interaction of digital signage is low and the level of engagement is high, a lot of memory information is formed that forms the overall attitude of the product. In addition, even though the interaction level is high and the engagement is low, the attitude cognitive response through the overall evaluation is formed rather than the attribute information. Third, brand attitude was positive when interactivity level was high and engagement level was high.

This study demonstrates the influence of environmental conditions, other than iron, on pyoverdin production by fluorescent Pseudomosonas. In slightly acidic pH conditions(pH 6), cell yield was reduced while the siderophore production per cell yield was increased. The optimum temperatures for the siderophore production and cell yield was $19^{\circ}C$ and $28^{\circ}C$ for 7NSK2 and $12^{\circ}C$ and $19^{\circ}C$ for ANP15. The carbon and nitrogen balance showed that at low C : N ratio of the growth medium (higher nitrogen concentration), both cell yield and siderophore production was reduced. Use of different carbon sources revealed that citrate as a carbon source facilitated iron uptake and resulted in a significant reduction in siderophore production. However, at the late exponential phase, the iron content in the cell biomass was not significantly different from those grown in glucose or succinate. From these results it can be suggested that the environmental factors other than iron may also influence siderophore production by fluorescent pseudomonas.

The general opinion about the notion of cyberbullying hasn't existed yet, but in related laws it is defined as the entire behavior causing the counterpart to suffer the pain by continuously and repeatedly psychologic offending toward specific students with information and telecommunication products such as the Internet and mobile phones, and spreading the private information or false facts related with specific students. Recently a number of accidents related with abuse of cyberbullying are being broadcast on a variety of mass media, and the argument about the severity and countermeasures against cyberbullying is moving onward. This study has a purpose as suggesting the practical alternatives to prevent cyberbullying victim of middle school students by arguing cyberbullying of middle school students and analyzing the relationship between the general features such as victimized experience and frequency and the emotional behaviors according to victimized experience. As the result of this study, cyberbullying victimized experience has a significant effect on the emotional behavior such as depression, aggression, and academic stress. As political implication, this study suggests the practical alternatives to prevent cyberbullying of middle school students based on the analysis result.

The purpose of this study is to verify the effect of SNS addiction on cyber-bullying among adolescents, considering the adjustment effect of friendship on this relationship. This study involved 811 middle/high school students with a gender distribution of 391 males and 420 females. According to the analysis, the higher the level of SNS addiction, the higher the level of cyber-bullying. A hierarchical regression analysis was conducted to verify the moderating effect of friendship. The result shows that better peer communication and reliance lowers the impact of cyber-bullying from SNS addiction. Based on research results suggesting the popularization of proactive pre-diagnosis programs to solve SNS addiction, practical intervention plans and the limitations of research on SNS addiction and cyber-bullying in youth are suggested.

사이키델릭의 어원적 의미는 그리스어로 정신을 나타내는 사이케(psyche)와 영어로 섬세함을 지칭하는 델리커시(delicacy)의 합성어이다. 또한 환각제의 복용에 따른 환각상태를 뜻하는 LSD로 대표되는 말이기도 하다. 인간은 일반적으로 환각제를 복용하면 통상적인 정신과 감각의 해방감을 맛보게 되고 이것이 확대되면 일종의 환각상태에 빠지게 되는데, LSD상태에서 느끼게 되는 감각의 해방과 체험을 사이키델릭이라고 한다. (중략)

본 연구는 발전 기술이 다양한 우리나라 원자력 발전소들 사이의 운전 경험에 대한 정보가 원자력 발전소의 운전 성과에 미치는 효과를 실증적으로 분석하는 것을 목적으로 하였다. 기존의 원자력 발전의 학습 효과 분석은 주로 단일 발전소를 대상으로 수행되었다. 그러나 어떤 발전소의 운전 경험이 운전 성과에 미치는 효과는 그 발전소에만 국한되는 것이 아니고 다른 발전소에도 영향을 줄 수 있으므로 발전소들 사이의 운전 경험에 대한 정보의 공유에 대한 분석이 요구된다. 그런데 모든 발전소의 운전 경험이 동일한 가치를 가지고 있다고 볼 수는 없다. 동일 부지와 동질적 발전 기술을 가진 발전소들 사이에는 운전 경험의 운전학습효과가 클 것이지만 다른 부지와 이질적 발전 기술의 발전소들 사이에는 운전 경험에 관한 정보의 공유 비용이 높을 것으로 기대된다. 본 연구의 실증 분석 결과, 동질적 기술을 가지고 있는 발전소들 사이의 운전 정보의 공유가 대체적으로 더 활발한 것으로 분석되었으며 동일 부지에 있는 발전소들의 운전 경험이 운전 성과 향상에 미치는 효과가 큼을 알 수 있다. 이러한 실증 분석 결과는 예상과 일치하는 것으로 기존의 다양한 원자력 발전 기술의 도입이 발전소의 운전 성과 측면에서는 비효율적이었음을 지적하는 것이다.

현재 현장에 설치되어 운용되고 있는 대부분의 디지털사이니지는 독자적인 설계와 구현으로 개발되었기 때문에 다른 시스템과 연동이나 상호 운용하기에는 많은 어려움이 있다. 향후 웹 기반의 개방형 디지털사이니지가 주류를 이룰 것으로 예상됨에 따라, 다양한 서비스나 단말장치와 연동할 수 있는 상호 운용성을 갖춘 솔루션을 위한 기술 표준화 작업이 활발하게 진행될 것으로 예상된다. 최근 몇 년 전부터 ITU-T, POPAI, W3C 등을 중심으로 디지털사이니지 기술 표준화가 진행되고 있으며, 국내에서도 디지털사이니지 산업이 성장하면서 표준화에 대한 관심이 고조되고 있다. 이에 본고에서는 ITU-T, POPAI, W3C, 일본 등 해외에서 행해지고 있는 최근의 표준 활동과 TTA를 중심으로 한 국내의 표준 활동을 소개한다.
