The aim of this study is to explore 'how is ICT being used in social work education and are they effective?' In order to answer the questions, a content analysis was conducted. Three academic databases, DBPIA, Kiss, EBSCO were searched to look for the articles that investigated ICT and social work education between Jan. 2016 and July, 2022. No study was found from DBPIA and Kiss. Based on inclusion criteria, thirteen articles were selected from EBSCO. Those articles were analyzed following 9 analytic themes: Country, Undergraduate or Graduate Student, Pedagogical Theory, Course Goal, Course Content, Evaluation Method, Outcome, Applied Software or Program. As results of the study, the platforms primarily used for social work education were VR, Second Life, PeopleSIM, course-tailored Applications. In addition, the following was illustrated as effectiveness of ICT in social work education; immersiveness, course satisfaction, improved knowledge, etc. Study limitations and recommendations of future applications were also discussed.

In this study, our primary focus was on preserving the unique characteristics inherent to the medium of printmaking art, such as cultural implications and formal features, during the digital transformation of traditional printmaking. We investigated methods to incorporate augmented reality (AR) technology into the creation process of traditional printmaking. To help understand the intended fusion of traditional printmaking art and AR technology in this digital transition era, we categorized AR artworks into four types and conducted an analysis of various AR artwork examples from across the globe. From this analysis, we derived the methodologies and design directions for combining AR technology with traditional printmaking. Moreover, we created an AR printmaking piece based on the author's artwork "Spring, Summer, Fall, Winter," thereby demonstrating the significant role AR technology can play in the evolution of printmaking. Through this research, we were able to verify the potential and value of AR printmaking as an immersive art form capable of providing a more expansive narrative.

This study presents a step-by-step analysis of the experiences and discussions of five elementary school teachers while developing the Augmented Reality (AR) science educational materials, using the Unity Physics Engine. In the preparation phase to develop the AR materials, the teachers explored the features of the AR technology and decided to create AR materials for experiments related to magnetic fields in the magnetism unit, based on discussions about the unit selection. In addition, they complained about difficulties arising out of the lack of background knowledge about the C# programming language in the preparation phase. During the material development stage, there were difficulties in operating the unfamiliar interface and other functions of the software. However, this was overcome through knowledge sharing and collaborative communication among the teachers. The final materials developed were marker-type AR materials to perform experimental activities by changing the position of the magnet and the compass markers. Based on the developed materials, the teachers discussed their smooth utilization during the classroom activities.

Through right deduction of theoretical equations and some disposal technique, a 3-dimensional strip rolling coupled analysis software has been successfully developed in this paper, which considers strip plastic deformation and roll elastic deformation simultaneously. The calculated examples with different kinds of rolling conditions all conform to the reality, and results show that the developed 3-dimensional program is applicable to the wide strip.

This study concerns logistics support analysis record(LASR) which provides guaranteed support, and is needed in various weapon systems development and acquisition to develop the optimal factor for integrated logistics support(ILS) by reflecting the results of logistics support analysis(LSA). We observe and analyze the logistics management information(LMI) system used in the United States under the integrated data environment(IDE), and analyze the differences between logistics management information system and the LOADERS(logistic support analysis data entry and retrieval system) which is currently used in Korea. Based on the analyzed results, a improvement model that corresponds to reality and can be applied is presented.

Stochastic phenomena induce us to construct a probability model and structure our thinking; corresponding models help us to understand and interpret the reality. They in turn equip us with tools to recognize, reconstruct and solve problems. Therefore, various implications in terms of methodology as well as epistemology naturally flow from different adoptions of models for probability. Right from the basic scenarios of different perspectives to explore reality, students are occasionally exposed to misunderstanding and misinterpretations. With realistic examples a multi-faceted image of probability and different interpretation will be considered in mathematical modelling activities. As an exploratory investigation, mathematical modelling activity for probability learning was elaborated through semiotic analysis. Especially, the coherence structure in mathematical modelling discourse was reviewed form a semiotic perspective. The discourses sampled from group activities were analyzed on the basis of semiotic perspectives taxonomical coherence relations.

최근에 TV 방송에서 가상스튜디오나 가상캐릭터와 같은 가상현실(VR:Vinual Reality) 기술이 자주 사용되고 있으며, 증강현실(Ah: Augmented Reality) 기술에 대한 관심도 높아지고 있다. 본 논문에서는 증강현실 기술을 방송에 응용한 가상스크린 시스템에 대해 소개한다. 가상스크린 시스템은 움직이는 색상패턴 패널을 추적하여 실시간으로 그 위에 동영상을 합성하는 증강 영상 시스템이다. KBS 기술연구소에서는 가상스크린 시스템을 개발하고 'K-비전'이라 이름지었다. 이 시스템은 사용자가 들고 움직이는 패널에 동영상이나 그래픽 영상 등을 보여줄 수 있는데, 보여지는 모든 영상은 카메라의 움직임과 패널의 움직임에 따라 정확하게 입혀진다. 패널 추적을 위하여 블럽분석(blob analysis)이나 특징추적(feature tracking)과 같은 영상처리 기술을 이용한다. K-비전은 모든 타입의 카메라와 사용 가능하며, 특별한 부가장치가 필요하지 않다. 센서를 부착하지 않아도 되고, 캘리브레이션(calibration) 과정 또한 필요하지 않다. K-비전은 선거개표방송, 다큐멘터리, 오락 프로그램 등 생방송 프로그램에서 활용한다.

By using modeling and simulation. today's design engineers are simultaneously reducing time to market and decreasing the cost of development, while increasing the quality and reliability of their products. A driving simulator is the best example of this method and allows virtual designs of control systems, electronic systems, mechanical systems and hydraulic system of a vehicle to be evaluated before costly prototyping. The objective of this Paper is to develop the virtual Proving: ground using a driving simulator and to show its capabilities of an automotive system development tool. For this purpose, including a real-time vehicle dynamics analysis system, the PC-based driving simulator and the virtual proving ground are developed by using VR(Virtual Reality) techniques. Also ABS HIL(Hardware-In-the-Loop ) simulation is performed successfully.

The purpose of our research is to identify the critical variables and to develop a new methodology for market segmentation of online game market. Our research tested the model with Korean online game users because Korean online game industry is the frontier of global online game industries. Conclusively, the critical variables are the suitability of feedback, the reality of design, the precision of information and the involvement of virtual community. The analysis of segmentation shows that the primary target audiences are positively influenced by the reality of design and the involvement of virtual community. To attract the primary target audiences, online game companies should develop strategies depending on the effectiveness of the variables and the demographic and behavioral characteristics of target audiences.
