Extended reality (XR) provides an immersive virtual experience by using various media. The XR virtual environment enables interactions between the real and virtual worlds in virtual, augmented, and mixed reality scenarios. XR is being used in various areas such as industry, medical care, road transportation, gaming, education, and culture. XR and multimedia enhancement are important business scenarios for fifth-generation (5G) mobile networks. As users' demand for emerging media services gradually increases, enhancements in networks should be implemented for delivering multimedia services such as XR. We describe related standardization trends and requirements of the XR service in 5G mobile networks. We also discuss technological enhancements for 5G mobile networks as specified by the 3GPP SA2 working group.

높은 몰입감과 실재감을 제공하는 XR 기술이 고령자들의 인지능력, 주의력, 시각적 기억력에 긍정적인 영향을 주는 것으로 나타나며 노인의 건강과 삶의 질을 향상시키기 위한 기술로 많은 관심을 받고 있다. 본 연구는 인지기능 향상을 위한 XR 융합훈련프로그램에 사용될 콘텐츠 저작 시 젊은이와 노령층의 디지털 격차, 선호도의 차이, 노화에 따른 신체·인지능력의 저하 등 고려해야 할 이슈를 소개하고, 문제를 해소할 수 있는 XR 콘텐츠 저작도구를 제안한다.

Extended Reality (XR) technology, the umbrella term covering hyper-realistic technologies, is known to enhance consumer experience and is therefore developing rapidly and being utilized across various industries. Growing studies have examined XR technology and consumer experience; however, the literature has failed to fully explore hyper-realistic technology through a holistic perspective. To fill this gap, we analyzed 720 Korean and international articles through semantic network analysis and topic modeling and identified the literature on XR research in consumer experience. As a result, we extracted six main topics: "Tourism," "Buying Behavior," "XR Technology Acceptance," "Virtual Space," "Game," and "XR Environment." The results provide comprehensive insight on XR technology in consumer experience, whereas the literature is bounded on the production side as revealing a lack of academic discourse on consumer rights and responsibilities. Research reflecting the consumer welfare perspective is, therefore, recommended for future studies.

In this study, the concept of eXtended Reality Devices(XR) is defined, how it is applied by industry and how it will develop in the future, and based on the expanded integrated technology acceptance theory and innovation resistance, We tried to confirm through empirical analysis how the influencing variables affect. We carry out the analysis of the hypotheses using PLS Structural Equation Modeling. According to the empirical analysis results, this study confirms that innovativeness has a significant effect on UTAUT2's acceptance variables(performance expectation, effort expectation, hedonic motivation, price value) for XR devices, and these variables affect attitudes and acceptance of XR. and the pace of change of XR has a significant effect on perceived risk, and the perceived risk perceived by consumers mediates the pace of change and innovation resistance, and has a significant effect on innovation resistance. and innovation resistance to XR devices had a significant negative effect on acceptance. This study has its meaning because it found out that it deals expansively and comprehensively with personal innovation, the UTAUT2's acceptance variables, and the effects of perceived risk factors mediating the pace of change and resistance to innovation. In addition, it suggests that in order for innovative technologies such as XR to advance to the stage of market expansion, it is important to present strategies to reduce resistance to new technologies as much as the value to be provided to consumers.

최근 마이크로소프트 (Microsoft)에서 발표된 후 주목 받고 있는 JPEG XR 은 압축 효율 면에서 뛰어난 장점을 가지고 있다. 일반적으로 JPEG XR 은 기존의 JPEG 과는 다른 압축 과정과 주파수 성분 분포를 가지고 있다고 알려져 있다. 하지만 JPEG 압축 방식과 비교하여 JPEG XR 의 압축영역에서의 영상 필터 처리의 연구는 아직 미흡한 실정이다. 본 논문에서는 JPEG XR 의 압축과정과 주파수 성분 분포의 분석을 기반으로 효율적인 저역/고역통과 필터 함수를 제안하고, 체계적인 실험을 통해 제안한 필터함수의 효율성을 입증하였다.

Despite the growing educational demand for the extended reality (XR) convergence content creation for non-IT students, fewer studies have attempted to education material development. In this paper, non-IT students' requirement to create XR convergence contents was analyzed and designed framework system specification. The object-oriented application framework (OOAF) was developed for non-IT students to create XR convergence contents through simple interaction methods such as drag and drop in-game engines. To evaluate the developed framework XR contents development course was operated with 26 industrial design majors sophomore in university. More than 90% of students succeeded in working on prototype XR contents in Oculus Rift. This result will be expected to improve the quality of XR contents creation education for non-IT students and contribute to the growth of the future convergence contents industry.

The tensile bond strength to dentin was measured for three glass-ionomer cement and composite resin combinations: two light-curing glass-ionomer cements(Vitrebond and XR - Ionomer) and one traditional glass - ionomer cement(Ketac - Bond), two adhesive systems(Scotchbond, and XR - Bonding System), and a corresponding composite resin. The bond strength of this "sandwich" was also compared with that of the same cements used in bulk. Vitredbond showed a significantly higher bond strength in bulk than did the other two cements. Of the sandwiches, the XR - Iomomer and XR - Bond combination showed a bond strength significantly higher than that of the Vitrebond and Scotchbond or Ketac- bond and Scotchbond combination. The fracture of the bond was mainly adhesive for Vitrebond, cohesive for XR - Ionomer when used in bulk and adhesive - cohesive when used in a sandwich, and cohesive for Ketac-Bond.

전자상거래(e-commerce)의 발달은 과거의 전통적인 상거래를 IT기술을 이용한, 새로운 시장구조를 제공하고 있다. 특히 인터넷을 통한 소프트웨어, 게임, 동영상 등 디지털 컨텐츠(digital contents)에 대한 상거래가 크게 증가하고 있어, 이러한 디지털 컨텐츠의 유통에 신뢰를 제공할 수 있는 시스템, 즉 디지털 저작권관리(digital rights management system), 또는 디지털 지적 저작권관리(digital intellectual property system)에 대한 유통 비즈니스 모델이 필요하다. XrML은 권리(rights)를 명시하는 언어로써 본 연구는 XrML을 이용하여 저작권관리에 필요한 권리구조를 구현한 시스템(prototype)을 표현했다. 벤츠와 그에 따른 서비스들을 사용할 수 있는 권리와 조건들을 명시해준다. XrML은 현재 디지털 저작권관리(Digital Rights Management: DIPR)에 가장 많이 쓰이고 있는 Rights Language이다. XrML은 ContentGuard가 개발한 DIPR 서술 언어로 전 세계 산업계 표준으로 추진하기 위하여 파트너 회사 확대, 기능 확장, 무료 / 공개 형식으로 보급을 추진중이다.

본 논문은 제조 산업 현장에서의 업무 능력 향상을 위한 XR 교육훈련 콘텐츠의 가변적 시나리오를 제안한다. 가변적 시나리오를 적용한 XR 교육훈련 콘텐츠는 교육훈련 관리자가 자유롭게 시나리오를 가감할 수 있어 동일한 콘텐츠 내에서 다양한 시나리오로 콘텐츠를 구성할 수 있는 특징을 가진다. 이는 기존 하나의 시나리오로 반복되는 교육훈련의 한계를 해결할 수 있으며, 현장에서 발생할 수 있는 돌발적 상황 및 변화되는 업무 프로세스를 효과적으로 진행할 수 있을 것이다.

이 논문은 서비스를 제공하는 로봇과 사용자가 상호작용하는 새로운 방식의 XR 인터페이스를 제안한다. 사용자는 제안한 XR 인터페이스를 통해 현실을 모사한 XR 공간 내에서 서비스 로봇에게 직관적으로 서비스 작업이나 공간 이동을 요청하고, 요청한 작업을 편리하게 관리할 수 있다. 이러한 명령, 이동, 편집은 용이하게 전환된다. HTC VIVE 와 Unity 엔진을 사용하여 프로토타입을 구현하였다. 추후 인터페이스를 실제 로봇 시스템과 통합하고, 사용자 테스트를 수행하여 사용성 향상을 검증하고자 한다.
