지구과학 학습 내용들은 교실이나 실험실에서 통제하기 어려운 내용들이 많다. 따라서 이를 극복할 수 있는 하나의 방안으로 가상현실 기술을 도입하여 웹상에서 활용할 수 있는 3D 가상현실 학습프로그램을 개발하였다. 개발된 프로그램은 701명의 중학교 학생들에게 투입되었다. 그 결과 몰입감을 통한 흥미유발 및 동기유발에 아주 긍정적인 효과가 있었으며, 공간지각 능력 향상에도 큰 도움이 되는 것으로 보여졌다.

The purpose of this study was to analyzed the current status of the of the Virtual Reality-based education for healthcare students in Korea. Five databases (KoreaMed, KMbase, NDSL, KISS, KiSTi) were searched prior to July 2022. A total 10 articles met the inclusion criteria. 5 articles developed VR-based education contents and the other 5 articles were using vSim already developed as a VR education program and evaluated the effectiveness. As a result of this literature review, VR-based education program was found to be effective in improving the healthcare students' competency. VR-based education program could be considered to improve the healthcare students' clinical practice ability.

A low cost PC based simulator for excavator manipulation has been developed using virtual reality technology. The simulator consists of two joystick input devices, server and client PCs, an excavator kinematics module, and a graphic rendering program Open Inventor. In order to use two joysticks in the PC window environment multi-thread programing with network protocol TCP/IP has been used. To provide realistic view to the operator, CAD program Pro/Engineer and 3D modeller have been employed to create 3D part geometry of tile manipulator and virtual environmental geometries. Those geometries also have been transformed and imported to the Open Inventor. The Simulator developed is to be improved for more realistic excavator operational training.

PURPOSE: This study compared the effects of computer-based and virtual reality-based cognitive rehabilitation programs on the cognitive function, upper limb function, activities of daily living, and their impact on the prefrontal cortex in convalescent stroke patients. METHODS: Ten recovering stroke patients were assessed for their cognitive function, upper limb function, and daily living activities using the Neurobehavioral Cognitive Status Examination, the Korean version of the Fugl-Meyer Assessment, and the Korean version of the Modified Barthel Index. The prefrontal cortex activity was measured with functional Near Infrared Spectroscopy. The virtual reality-based cognitive rehabilitation group utilized a program of daily living activities delivered via a laptop and Oculus Rift. The computer-based cognitive rehabilitation group performed various cognitive tasks on an all-in-one PC. Both groups underwent cognitive rehabilitation training for 30 minutes per day, three times a week, for six weeks, with identical conventional rehabilitation therapies in the hospital. RESULTS: Both programs positively impacted the cognitive and physical functions. On the other hand, the virtual reality-based cognitive rehabilitation program had a larger influence on improving the cognitive and physical functions of convalescing stroke patients. CONCLUSION: The virtual reality program suggests its potential to enhance cognitive and physical functions in convalescent stroke patients through increased engagement, focus, real-time feedback, and game elements, making it a promising rehabilitation approach.

가상현실로 구축된 박물관의 전시공간은 현재와 다른 차원에 존재하는 현실로써 시공간의 제약을 받지 않기 때문에 효율적인 박물관 운영을 위한 실천방안이 될 수 있다. 특히 움직일 수 없는 물리적 공간을 이동 가능한 콘텐츠로 바꾸어주는 가상현실의 특성은 '박물관 밖 박물관'을 표방하는 박물관 아웃리치 프로그램에서 다음과 같은 긍정적 효과를 불러온다. 첫째, 물리적 환경에 구애받지 않는 편의성으로 보다 많은 사람들에게 박물관 경험의 기회를 제공한다. 둘째, 전시동선을 따라가며 박물관의 콘텐츠들을 맥락적으로 이해할 수 있게 한다. 셋째, 동일한 전시를 동시기에 관람할 수 있어 의미공유를 통한 사회적 담론 형성이 가능하다. 넷째, 전시교체가 손쉽고 이용자들에게 풍부한 콘텐츠를 제공할 수 있다. 다섯째, 전시공간을 그대로 기록함으로써 아카이브로서의 가치가 높다. 여섯째, 오감을 통한 직접경험 방식이 관람객들을 관찰자에서 능동적 조작자로 전환시킨다. 일곱째, 아웃리치 프로그램의 참여 대상층을 넓히고 그에 맞는 교육콘텐츠를 개발할 수 있다. 이처럼 박물관에서의 가상현실 도입은 전시공간을 확장하여 박물관 경험의 기회를 증폭시킨다는 점에서 박물관이 문화복지를 실현하고 소통력 높은 공공기관이 되기 위한 지름길이 될 것이다.

Purpose: We developed a virtual reality (VR) program for use in pediatric nursing practicums to help nursing students learn to measure vital signs in children. Methods: The analysis, design, development, implementation, and evaluation model was employed between July 2021 and December 2021 at a university in South Korea. In the analysis phase, in-depth interviews were conducted with four nursing students, two nursing school graduates, and four experts. The topic and contents of the VR program were settled in the design phase. The VR program was developed and subsequently used and evaluated by 20 nursing students and four experts. Results: The contents of the VR program for pediatric nursing practicums included the measurement of vital signs in a newborn baby and a young child, as well as an evaluation system. The mean score for the nursing students' satisfaction with practice was 4.02 out of 5 points. The mean scores for overall satisfaction with the VR program were 4.15 and 4.79 out of 5 points for nursing students and experts, respectively. Conclusion: The VR program developed in this study allows nursing students to practice measuring vital signs in children, thus improving the students' clinical performance in pediatric nursing.

목적 : 본 연구는 가상현실 프로그램을 통해 뇌졸중 환자의 낙상 효능감과 일상생활활동에 미치는 영향을 알아보고자 하였다. 연구방법 : 뇌졸중 진단을 받은 환자를 대상으로 총 4주 동안 가상현실 프로그램 중재를 받는 실험군 10명과 작업치료 중재를 받는 대조군 10명으로 나누어 실시하였다. 치료 중재 전 후 낙상 효능감을 비교하기 위하여 낙상 효능감 척도(Fall Efficacy Scale: FES)를 시행하였고, 일상생활활동 수행능력을 비교하기 위하여 기능적 독립척도(Functional Independence Measure: FIM)를 시행하였다. 결과 : 실험군과 대조군의 치료 중재 전 후 뇌졸중 환자의 낙상 효능감과 일상생활활동 수행능력은 통계학적으로 유의한 차이를 보였고(p<.05), 실험군이 대조군에 비해 통계학적으로 유의하게 낙상 효능감과 일상생활활동 수행능력이 향상되었다(p<.05). 결론 : 작업치료와 더불어 가상현실 프로그램을 적용할 때 뇌졸중 환자의 낙상 효능감과 일상생활활동 수행능력을 향상시킨다는 것을 알 수 있었다. 따라서 가상현실 프로그램이 뇌졸중 환자의 낙상 효능감과 일상생활활동 수행능력을 위한 치료방법으로 작업치료와 더불어 임상에서 유용하게 적용될 수 있을 것이다.

E-learning is a new teaching model nowadays, and Virtual Reality (VR) technology is reported that the use of virtual reality as an education tool can increase student interests, understanding, and creative learning because of encouraging students to learn by exploring and interacting with the information on the virtual environment. Besides that, LEGOs have long been the favorite of many children. LEGOs provide a mechanism to understand and do for many concepts from spatial relationships to robotics platforms. In this paper, we present a virtual reality application based on the assembly of LEGO-Like bricks to increase math and science learning by improving spatial thinking. It not only encourages students to pursue careers in science, technology, engineering, or mathematics but also enhances learner's ability to analyze and solve problems. The application is built by Processing 2.0 as the easier programming language which is a top-down approach to build the 3D interactive program.

Purpose: The purpose of this study was to investigate the effects of virtual reality based treadmill training on muscle architecture of gastrocnemius in chronic stroke patients. Methods: Thirty chronic stroke patients were randomly assigned to either the virtual reality based treadmill training (VRTT) group (n=15) or treadmill training (TT) group (n=15). Both groups participated in a standard rehabilitation program; in addition, the VRTT group participated in virtual reality based treadmill training for 30 minutes per day, three times per week, for 6 weeks, and TT group participated in treadmill walking training for 30 minutes per day, three times per week, for 6 weeks. Ultrasound image was used for measurement of pennation angle and muscle thickness of the medial gastrocnemius muscle at rest and during maximum voluntary contraction. Results: In the paretic side medial gastrocnemius muscle, greater improvement on the pennation angle and muscle thickness while resting and maximal voluntary contraction were observed in the VRTT group compared with the TT group. Conclusion: Findings of this study demonstrated that the virtual reality based treadmill training has an effect on muscle architecture of medial gastrocnemius in chronic stroke patients.
