해상에서 운항되는 선박에서 인명사고가 발생하면 육상과 달리 적시에 의료지원을 받기 구조적으로 어렵다. 특히 연안선박의 경우 원양선에 비해 상대적으로 고령의 선원들이 승무하고 있기 때문에 인명사고가 빈번하며 인명사고에 취약하다. 본 연구는 AR과 VR과 같은 실감기술을 기반으로하는 연박선박의 원격의료지원 모델 개발하기 위한 방향성을 제시하고자 한다.

최근 가상현실 및 증강현실 기술을 응용한 콘텐츠 개발이 활발하다. 증강현실 기술은 가상현실 기술과 다르게 현실세계와 컴퓨터 그래픽과의 융합을 토대로 개발된다. 때문에 증강현실은 현실감, 몰입감을 극대화 하는 방향으로 개발되고 있다. 그러나 현실과 컴퓨터 그래픽은 서로 다른 차원에 존재한다. 이를 해결하기 위해 마커검출 기법과 오차를 미리 계산해 출력 전에 반영해주는 방식이 제시되었지만 이는 사용자의 자유도 향상과 공간적인 제약을 최소화하기에 부담이 크다. 본 논문에서는 캘리브레이션을 통한 증강현실 구현결과로서 사용자의 관절 정보를 증강현실 내 캐릭터의 관절과 맵핑한다. 이는 사용자의 움직임을 캐릭터와 동기화함으로써 증강현실의 자유도와 몰입도를 향상시켰다. 제안된 증강현실 시스템은 사용자의 생활에 적용될 수 있는 범위가 넓어지고 사용자의 편의를 향상시킬 수 있는 가능성이 높였다.

The purpose of this study is to identify the differences in self-efficacy, clinical performance ability, and critical thinking disposition after applying education integrated educational virtual reality simulation to training and outside school clinical practice to nursing college students and to provide them as basic data for effective practical education. This study was conducted from June 8 to July 3, 2020, and enrolled in the 3rd year of university in G city, and 30 subjects who did not receive virtual reality simulation training or outside school clinical training at all. Data were analyzed by Paired t-test. As a result of the study, the result of pretest and posttest to each group showed statistically significant improvements in self-efficacy, clinical performance ability, and critical thinking disposition. As a results of the study, education integrating virtual reality simulation training and clinical practice for nursing students to improves clinical performance ability, improves critical thinking, and self-efficacy, so it is thought that various virtual reality simulation training must be suitable for clinical situations before practice is necessary.

Although various kinds of VR services are being carried out in the tourism field, The virtual reality experiences are still costly, since they could be realized in a limited space with some kinds of expensive equipment such as HMD. In this study, we propose a mobile virtual reality tourism experience using an easy and simple Google card board and user's smartphone because most tourist sites are outdoors and most of users like enjoying sightseeing and experience at the same time. For this purpose, we constructed a system that provides tourist information in real time employing both the IoT and VR techniques. Especially we develpoed a tourism contents for the UNESCO World Heritage Communities of Baekje Historical Site and Songsanri Tumulus. In addition, we virtually restored the royal palace in Gongju and confirmed the historical experience by VR flatform could be popular with people.

Augmented reality (AR) or virtual reality is suitable to apply the contents of a textbook so as to be directly observable by learners. This study aimed to examine the applicability and technology acceptance of anatomy learning using AR in nursing students. This study was conducted in May 2019 with 17 nursing students who studied an anatomy textbook using AR and answered a questionnaire about technology acceptance and the usability of AR in combination with the anatomy textbook. Perceived usefulness was identified as an influencing factor on technology acceptance with 51.2% acceptance rate and thus should be taken into consideration in the development of learning strategies using new technological learning methods.

IT convergence technology is gradually becoming anthropocentric and evolving based on the low-carbon green growth. Augmented reality technique is a contents convergence technology that can mix virtual objects while maintaining a sense of the real world. For that reason, interaction between user and system is possible, can make various applications, and has a high possibility for expandability. To expand the scope of existing interaction, this paper suggests contextual UX-based augmented reality system. It is a system which creates virtual objects that respond to the changes in the real world environment, and users can directly apply their personal preferences to virtual objects. Also, several virtual objects can be registered all at once, and even shows animations corresponding to either day and night according to the brightness of illumination. As said, it improves user's satisfaction through a system of mixed usability, and leads to a continuous use of augmented reality contents.

The purpose of this study was to investigate the trends in research on the effects of virtual reality technology applied to rehabilitation for disabled. I have collected 60 papers published in Korea(2000-2014), and analyzed it by the P.I.C.O. method. As a result, adults and the elderly are most common subjects, and projection type has been used frequently in researches. It were included mostly balance, upper extremity function, and gait that the dependent variables represents the intervention effects. I interpreted it as the ICF factors. So, research topics were the most common mobility, in contrast to educational, vocational, recreational area as dealing with the participation area is very small. In the future, we should focused on social aspects for useful intervention in real life of people with disabilities based on virtual reality technology, and virtual reality technology should be easy to apply in terms of cost and accessibility.

The purpose of this study was to compare and analyze special teachers' perception on virtual reality based intervention program.(VRIP) for students with disabilities. The survey participants consisted of 364 special teachers who were working in special class or special school. Questionnaires with unfaithful responses were excluded, and a total of 324 questionnaires were analyzed. Data analysis was carried out through independent t-test and ANOVA. According to the results of study, Male special teachers' acceptance intention towards VRIP were higher than female special teachers. Special teachers with educational career within 10 years had more positive awareness than special teachers with educational career above 15 years. Special teachers in middle and high school teachers were higher than special teachers in kindergarten. In the aspects on another factors, special teachers with educational career within 10 years more positive awareness than special teachers with educational career above 15 years. Special teachers in middle and high school teachers were higher than special teachers in kindergarten.

The purpose of this study were to analyze effects of VR-based intervention on daily living skills and class attitudes of students with intellectual disabilities. To do this, 30 students with intellectual disabilities in the second and third grades of middle school were selected for this study and placed three group. A group took part in a class using only VR program, B group participated in experience activities program, and C group got in the intervention program that combine VR program and experience activities on daily living skills. Intervention programs were conducted 4 times in a week for 4 weeks from the fourth week of July to the third week of August and a class time of each class was 50 minutes. Evaluations were carried out in pre- and post-test. The Evaluation data were analyzed by One-way ANOVA and scheffe'. In Result of study, daily living skills of C group was improved more higher than other groups and class attitudes of C group was improved more higher than group B. These results showed that the intervention combining VR program and direct experience activities was more effective than the other methods.

Recently, with the rapid development of eXtended Reality(XR) technology, the development and use of education and training systems using XR technology is increasing significantly. In particular, in areas that involve great risks and high costs such as military training and counter-terrorism training, the use of XR based simulators is preferred because they can improve training performance, reduce training costs, and minimize the risk of safety issues that may occur in actual training, by creating a training environment similar to actual training. In this paper, we propose a plan to build and evaluate an XR based hyper-realistic counter-terrorism education, training, and evaluation system to improve the ROK police's ability to respond to terrorist situations using the 5G and AR based Integrated Command and Control Platform previously developed by the Korea Military Academy. The proposed system is designed to improve counter-terrorism capabilities with virtual training for individual and team units based on hyper-realistic content and training scenarios. Futhermore, it can also be used as a on-site command and control post in connection with a simulation training site and an actual operation site.
