The study investigated undergraduates' citation use and plagiarism awareness. A questionnaire method was used and was given to undergraduates in a university located in Seoul. Upon investigation, undergraduates recognized the importance and the need of citation and were partly applying citations. However, upon further investigation of undergraduates' citation learning with citation questions, very few of respondents had knowledge of correct citation usage. Undergraduates mostly cited print materials and information from the internet. They used books in case of print materials and web materials provided by academic institutions. They suggested that the university should teach citation usage through a citation and plagiarism awareness program. It is necessary for library use education (information literacy education) as well as university to teach citation education including citation type and how to write it.

Recent Korean popular films and television dramas represent journalist as the character who colludes with corrupt power to engage in scandals or completes one's goals by good or bad means. It matters that the negative discourse of journalists fosters audience's distrust on journalism. Representation of journalists in popular culture is related to the reliability of journalism. In relation, it is noticeable that popular media represent female journalists. This study examines how recent popular films deal with female journalists through the case of (2011) and (2012) to find improvement of discourse on journalists. In result, three female characters in these films represent positively 'reformative leadership' (Chief Cho in ), 'appropriation of information technology'(Seong Hyo Kwan in ), and 'emotional response' (Jang Eun Seo in ). Compared to representation of journalists through male, the positive representation of female journalists constributes to positive discourse on role and function of journalism. However, it may be considered that these positive representations are merely a part of whole journalists.

In this study, a software education program based on blended learning using scratch was designed for pre-service elementary teachers' software education. Software education program was applied to experimental group and control group within the university of education using Scratch programming for 12 weeks. Blended learning using online lectures was applied to experimental group. The pre-service teachers' recognition about software education and self-evaluation of computational thinking were performed. Then, we analyzed the effect of the developed education program on the recognition of software education and computational thinking. As a result, the level of post-recognition of software education in the experimental group was significantly higher than that of the pre-recognition. In the self-evaluation of computational thinking, the experimental group was significantly higher than the control group. Therefore, it can be seen that the software education program based on blended learning can help improve the learner's computational thinking.

The context aware service is the service to provide useful information to the users by recognizing surroundings around people who receive the service via computer based on computing and communication, and by conducting self-decision. But CAS(Context Awareness System) shows the weak point of small-scale context awareness processing capacity due to restricted mobile function under the current mobile environment, memory space, and inference cost increment. In this paper, we propose a mobile cloud context system with using Google App Engine based on PaaS(Platform as a Service) in order to get context service in various mobile devices without any subordination to any specific platform. Inference design method of the proposed system makes use of knowledge-based framework with semantic inference that is presented by SWRL rule and OWL ontology and Jess with rule-based inference engine. As well as, it is intended to shorten the context service reasoning time with mapping the regular reasoning of SWRL to Jess reasoning engine by connecting the values such as Class, Property and Individual which are regular information in the form of SWRL to Jess reasoning engine via JessTab plug-in in order to overcome the demerit of queries reasoning method of SparQL in semantic search which is a previous reasoning method.

Through the Ukraine-Russia war, the military importance of drones is being reassessed, and North Korea has completed actual verification through a drone provocation towards South Korea at 2022. Furthermore, North Korea is actively integrating artificial intelligence (AI) technology into drones, highlighting the increasing threat posed by drones. In response, the Republic of Korea military has established Drone Operations Command(DOC) and implemented various drone defense systems. However, there is a concern that the efforts to enhance capabilities are disproportionately focused on striking systems, making it challenging to effectively counter swarm drone attacks. Particularly, Air Force bases located adjacent to urban areas face significant limitations in the use of traditional air defense weapons due to concerns about civilian casualties. Therefore, this study proposes a new passive air defense method that aims at disrupting the object detection capabilities of AI models to enhance the survivability of friendly aircraft against the threat posed by AI based swarm drones. Using laser-based adversarial examples, the study seeks to degrade the recognition accuracy of object recognition AI installed on enemy drones. Experimental results using synthetic images and precision-reduced models confirmed that the proposed method decreased the recognition accuracy of object recognition AI, which was initially approximately 95%, to around 0-15% after the application of the proposed method, thereby validating the effectiveness of the proposed method.
