We look at the initial stage of Meta (previous Facebook)'s new metaverse platform and investigate its platform design in pre-launch and ignition life stage. From the Rocket Model (RM)'s theoretical logic, the results reveal that Meta firstly focuses on investing in key content developers by acquiring virtual reality (VR), video, music content firms and offering production support platform of the augmented reality (AR) content, 'Spark AR' last three years (2019~2021) for attracting high-potential developers and users. In terms of three matching criteria, Meta develops an Artificial Intelligence (AI) powered translation software, partners with Microsoft (MS) for cloud computing and AI, and develops an AI platform for realistic avatar, MyoSuite. In 'connect' function, Meta curates the game concept submitted by game developers, welcomes other game and SNS based metaverse apps, and expands Horizon Worlds (HW) on VR devices to PCs and mobile devices. In 'transact' function, Meta offers 'HW Creator Funding' program for metaverse, launches the first commercialized Meta Avatar Store on Meta's conventional SNS and Messaging apps by inviting all fashion creators to design and sell clothing in this store. Mata also launches an initial test of non-fungible token (NFT) display on Instagram and expands it to Facebook in the US. Lastly, regarding optimization, especially in the face of recent data privacy issues that have adversely affected corporate key performance indicators (KPIs), Meta assures not to collect any new data and to make its privacy policy easier to understand and update its terms of service more user friendly.

Purpose: This study aims to comprehensively assess the characteristics and effectiveness of immersive virtual reality (VR) or augmented reality (AR) in nursing education among nursing students and nurses. Methods: A thorough search was conducted in seven databases (PubMed, Embase, Cochrane Library, CINAHL, RISS, KMbase, and KoreaMed) for randomized controlled trials (RCTs) published in English or Korean before February 20, 2024. The quality of the included RCTs was assessed using the revised Cochrane Risk of Bias tool for randomized trials. A random-effects model was applied for the meta-analysis using Review Manager 5.4. Results: Out of the 15,840 studies extracted, ten were selected. Of those ten, the majority (six, 60%) were conducted on education dealing with specific nursing situations. In addition to the use of immersive VR or AR during nursing education, lectures, debriefing, and discussion processes were applied together, and device usage orientation was also provided. The meta-analyses showed that immersive VR or AR in nursing education significantly improved knowledge (standardized mean difference, SMD=2.64; 95% confidence interval, 95% CI=1.10~4.17) and skills (SMD=0.58, 95% CI=0.02~1.15). Conclusion: Immersive VR or AR in nursing education can effectively enhance knowledge and skills. However, for their development and implementation, various factors should be considered, and these findings are expected to provide valuable evidence regarding that concern.

Purpose: This study aimed to evaluate the effects of health interventions using virtual reality (VR) on improving knowledge, attitudes, and skills; and inducing behavioral change among adolescents. Methods: This study is a systematic review and meta-analysis following PRISMA guidelines. We searched Cochrane, MEDLINE, Embase, CINAHL, Scopus, Web of Science, and Korean databases between database inception and April 10, 2021. Based on heterogeneity, a random- or fixed-effects model was used, as appropriate, to calculate effect sizes in terms of the standardized mean difference (SMD) and odds ratio (OR). Studies were selected if they verified the effects of health education using VR on adolescents; there was an appropriate control group; and if the effects of education were reported in terms of changes in knowledge, attitudes, skills, or behaviors. Results: This analysis included six studies (n = 1,086). The intervention groups showed greater responses in knowledge and attitudes (SMD = 0.57, 95% confidence interval (CI) [0.12 to 1.02]), skills related to health behavior (SMD = - 0.45, 95% CI [- 0.71 to - 0.19]), and behavioral change after 12 months (OR = 2.36, 95% CI [1.03 to 5.41]). Conclusion: The results confirm the effectiveness of health interventions using virtual reality (VR). Although the analysis include a small number of studies, a case can be made for health interventions using VR to be utilized as educational methods and strategies to prevent risky behaviors among adolescents.
