신재우(Shin, Jae Woo),김창현(Kim, Chang Hyun) 한국전시산업융합연구원 2018 한국과학예술융합학회 Vol.35 No.-

정보통신기술(Information Communication Technology, ICT) 분야에서 차세대 성장 동력으로 대두되고 있는 가상현실(Virtual Reality, VR)은 게임, 엔터테인먼트, 엔지니어링 등 다양한 주요 산업에서 채택되고 있다. 그중에서도 고령화 사회의 급속한 진행과 더불어 전문 인력 부족 등의 문제로 효율적인 의료서비스 제공을 위한 헬스케어 산업과의 접목이 주목을 받기 시작하면서 국내의 대기업뿐만 아니라 세계의 주요 기업들이 IT와 헬스케어의 융합 시장에 뛰어들고 있다. 그러나 기기 중심의 발전에 비해 VR 콘텐츠의 개발이 미흡하고, 의료목적이 아닌 운동 및 레저를 통한 건강관리, 즉 웰니스(wellness) 분야에의 시스템이 부족하다는 평가가 이어지고 있는 만큼, 다양한 시스템 개발과 콘텐츠의 육성을 통해 산업 성장을 견인할 필요가 있다. 따라서 본 연구에서는 사용자로 하여금 운동에 대한 거부감을 최소화하고 재미와 목표의식을 제공하여 꾸준한 운동을 통해 건강관리가 가능한 가상현실 기반의 헬스케어 시스템 개발을 제안한다. 특히 최근 들어 인체의 모든 힘과 운동성, 안정성을 발휘하게 하는 핵심 근육인 코어 근육에 대한 관심이 높아지고 있음을 체감하며 이를 수상보드라는 해양 레포츠와 접목하였다. 본 연구는 가상현실과 아직은 국내에서 그 시장성에 비해 관심이 미미한 해양레포츠 분야를 융합하여 향후 가상현실 기반의 헬스케어용 시스템 개발에 대한 새로운 방향을 제시한다는데 의의가 있다. Virtual Reality (VR), which is emerging as a next generation growth engine in the field of Information Communication Technology (ICT), has been adopted in various major industries including games, entertainment, and engineering. In particular, the healthcare industry has begun to receive attention due to the rapid progress of the aging society and the shortage of professional manpower, major corporations in the world as well as domestic corporations are getting into the convergence market of healthcare. However, research organizations remark that development of VR contents is insufficient compared with the development centered on devices, and lack of system for wellness (healthcare) through exercise and leisure, not medical purpose. Therefore, there is a need to drive industrial growth through fostering for various systems and contents. Therefore, this study suggests the development of a virtual reality - based healthcare system that enables users to minimize healthcare discomfort, provide fun and goal, and maintain health through continuous exercise. Especially, as interest in Core Muscle, which is the core muscle to exercise all the strength, mobility and stability of the human body, is increasing recently, the system is integrated with marine leisure sports, water board. this study is significant that the virtual reality is merged with marine leisure field which is still less interested in domestic market. Based on the results of this study, vitalizations of the study on virtual reality based healthcare system is expected.

With the advent of the Fourth Industrial Revolution, virtual reality, a technology that has recently attracted attention, is emerging as a core technology that will lead the future industry by changing the paradigm of various industries. The development of 3D rendering, computer graphics, and mobile technologies enabled the development of various smart devices and led to the popularization of virtual reality services using them. Recently, with the development of virtual reality-related technology, various devices and contents such as VR-related HMDs are being developed and released. However, since the classification for VR technology has not yet been established, it is difficult to define a range of industries and services to which VR can be applied. Therefore, in this study proposes a service classification system in terms of industries that can apply VR technology and services that can be provided based on the studies on industries and services of VR technology related to the Fourth Industrial Revolution. VR s industrial classification consists of eight industries including entertainment, media, education, medical care, architecture, manufacturing, distribution, tourism and each service is divided into two service categories and composed 16 services. Through the collection and analysis of virtual reality service cases, the service distribution and characteristics of each industry can be analyzed. In addition, we can develop a virtual reality new business model and present a service case for the intersecting areas. This study is expected to be used as a basic research for the activation of virtual reality services in the future.

호흡곤란 및 흉통을 주소로 내원한 환자에서 심낭삼출이 첫 증상으로 발현된 일차성 쇼그렌증후군을 건조증상, 침샘조직검사, 그리고 심낭삼출액 분석을 포함하여 진단하고 성공적으로 치료하였기에 문헌고찰과 함께 증례보고하는 바이다. Primary Sjogren’s syndrome (pSS) is characterized by lymphocytic infiltration to the lacrimal and salivary glands. However, it also includes a wide spectrum of clinical manifestations, including musculoskeletal, lung, kidney, neurological, and cardiac manifestations. Cardiac involvement in pSS leads to various conditions including pericardial effusion (PE), left heart failure, pulmonary hypertension, and left atrial hypertrophy. A large PE without pulmonary arterial hypertension is extremely rare and there has been no case in Korea, to date. We report a case of a 45-year-old woman with newly-diagnosed pSS who presented with a large PE and pleural effusion. The patient experienced a significant improvement of the PE following treatment with steroids. (Korean J Med 2016;90:88-92)
