The purpose of this study is to find out the effect of augmented reality contents based instruction for adult learners on academic achievement, interest and flow in learning. The subject populations were 80 students randomly sampled from an IT institute and they were evenly placed into two groups. One cell as an experimental group studied with augmented reality based contents and the other cell as a control group studied under textbook based instruction for two weeks. The experimental design of this study was the pre-posttest control group design. The results are summarized as follows: First, there was no significant difference in academic achievement between two groups. Second, the group studied with augmented reality based contents showed higher interest in learning than textbook based instruction group. Finally, there was a significant difference in flow in learning between two groups. The augment reality based instruction group showed higher scores of flow than the other group. The implication of this study is that augmented reality contents may have different effects for adult learners in academic achievement compared with younger learners.

The Republic of Korea Army (ROK Army) is trying to improve the effectiveness of education and training. On the other hand, there are many restrictions in actual training, limiting their practical education and training. Virtual reality technology is being used to overcome these limitations. Virtual reality technology is developing in various types, and the ROK Army needs to introduce a virtual reality training system for cost-effective education. The ROK Army mainly uses high-cost simulator-types that are similar to real equipment. Recently, a low-cost immersive-type virtual reality training system wearing an HMD is also being used. This study analyzed the cost education effectiveness of simulator-type and immersive-type virtual reality training systems in operation at the ROK Army air defense school. First, the research method used AHP to analyze the educational effects. Second, the cost was applied to the production cost of the virtual reality training system to analyze the cost-effectiveness of the education. The immersion-type was 3.4 times higher than the simulator-type in terms of cost effectiveness. These results can be used as basic data for analyzing the cost-effectiveness of a virtual reality training system.

본 논문에서는 지금 가장 대두가 되고 있는 재난 안전에 대해서 증강현실, 가상현실체험을 이용한 교육의 현황에 대해 조사하였다. 증강현실 및 가상현실은 지금 우리가 살고 있는 실세계를 그대로 반영한 기술이므로 이것을 통해서 대응과 교육 분야는 좀 더 실용적으로 접근할 수 있게 되었다. 어떤 것이든 지식이나 생각으로만 하는 것 보다 직접 몸으로 경험해보고 익히는 게 더욱 좋듯이, 체험자들은 실제로 재난상황들이 일어난 듯한 실감과 그에 따른 안전교육의 필요성을 경험한다. 이러한 상황은 재난상황을 증강현실 및 가상현실 기술을 통해 체험할 수 있게 하여 나중에 일어날 가능성이 있는 재해. 재난에 대해서 좀 더 신속하고 안전하게 대응할 수 있다는 효과를 기대하게 한다.

Using various types of educational media plays an important role in educating students with disabilities. In recent years, augmented reality has emerged as an important technology that can increase the effectiveness of special education programs. This study developed augmented reality contents focusing on the theme 'Weather and Life' in the 'Na' unit of the Basic Special School Curriculum, and explored the possibility of applying the contents to the science education. The contents design instructions and educational programs for this study were developed based on a focus-group interview conducted with five special school teachers and two developers. To explore the possibility of applying the augmented reality contents, a usability evaluation was conducted with 23 special school teachers and 18 students with intellectual disability. The results showed that the augmented reality contents had a high level of usability as the special school teachers received 4.73 and the students with intellectual disability received 4.75 out of 5. As a result of this study, we can draw a conclusion that there is a high possibility of applying augmented reality contents to science education for students with intellectual disability.

Technological development, a diverse range of media adapting to new technology has been developing. Augmented Reality Technology provides realistic information through the stereoscopic 3D images and it has been riding a wave of learner interest as an educational media which can broaden their learning experience through direct operating activity. The biggest reason why the Augmented Reality has gained such attention is because of its unique way of suggesting learning information that unlike the existing educational media, the Augmented Reality provides additional digitalized information while its users are looking at the actual object. Based on the domestic and foreign cases of development for educational contents using the Augmented Reality Technology, this thesis suggests the utilization of Pop-up books and multi-augmented Digilog Books that are ways to maximize the educational effects of the Augmented Reality. Through the development of smartphone applications that are propagating lately at a rapid rate, users can now use the Augmented Reality educational contents in a way that is easier than ever.

The purpose of the study was to review the evidence of effects of virtual reality (VR) technology in nursing education. Four databases were searched for articles publised until November 2018 that databases include PubMed, Proquest (nursing and allied health), CINAHL, & RISS. Key word used for search include 'education, nursing', 'simulation', 'skill training', 'virtual reality' and 'VR'. Of 695 papers searched, Seven studies were selected for data analysis. Of seven studies, five studies used quasi-experimental design and two used one group design. There were two studies used VR technology for skill training and five were scenario based VR simulation program. Studies evaluated outcomes including students performance, time spent on practice, self-efficacy and communication ability that most studies reported positive effects while some figures were not statistically significant. The findings of this study provides evidence of nursing education program using VR, however, additional research with rigorously designed studies using systematized measurements for study outcomes are required. In addition, comparison with existing skill training and simulation education should be considered in the future studies.

가상현실 (Virtual Reality, VR) 기술은 3차원 가상공간 내에서의 높은 몰입감에 기반한 체험을 바탕으로 다양한 분야에서 활용되고 있다. 소방훈련이나 태풍, 지진 등 재해 대응훈련과 같이 인명피해의 위험이 있는 재해에 대한 VR 기술을 활용한 방재교육은 위험성을 동반하지 않으면서도 현장감에 기반한 높은 교육적 효과를 창출할 수 있다. 한국전자통신연구원에서는 VR 기술을 이용하여 소방훈련을 위한 실감 소방훈련 시뮬레이터를 개발한 바 있으며 목동재난체험관에서는 홍수, 태풍, 지진 등 다양한 재해에 대한 안전교육을 위한 자연재해 가상현실체험을 운영하고 있다. 이외에도 전국 지자체 및 교육청에서는 방재교육을 목적으로 VR 기술을 활용하고 있다. 그러나 기존의 VR을 활용한 수재해 방재교육은 범람의 수리학적 특성과 함께 수해지의 지형적 특성을 적절히 반영하지 못하는 단점을 가지고 있다. 이는 방재교육이나 경각심을 부각하는 데엔 효과적이나 실질적인 방재 가이드라인을 제시하는 데엔 한계가 있다. 본 연구는 몰입형 파랑해석모형인 Celeris Base를 기반으로 3차원 가상현실 시각화를 활용한 수리학적 홍수추적 모형을 개발하였다. 3차원 가상현실 시각화는 Unity3D를 이용하여 모의환경 내에 구현되었다. 강우-유출 과정의 수리학적 해석을 위해 동수역학 수치모형의 연속방정식 내에 강우와 침투에 대한 항을 추가하였다. 침투모형으로는 Horton 모형, Green-Ampt 모형과 함께 사면의 기울기를 고려한 Green-Ampt 모형을 적용하였다. 실제 유역에서의 홍수추적 모의결과는 관측값과 비교적 잘 일치함을 확인하였다. 개발된 모형은 VR 방재교육을 통해 일반인의 수재해 대응능력 향상에 기여함과 동시에 정확성 높은 홍수추적 모의결과에 기반한 홍수대책 마련에도 활용 가능할 것으로 기대된다.
