Recently, the emergence of 3D cameras, 3D scanners and various cameras including Lidar is expected to be applied to applications such as AR, VR, and autonomous mobile vehicles that deal with 3D data. In Particular, the 3D point cloud data consisting of tens to hundreds of thousands of 3D points is rapidly increased in capacity compared with 2D data, Efficient encoding / decoding technology for smooth service within a limited bandwidth, and efficient service provision technology for differentiating the area of interest and the surrounding area are needed. In this paper, we propose a new quality parameter considering characteristics of 3D point cloud instead of quality change based on assumed video codec in MPEG V-PCC used in 3D point cloud compression, 3D Grid division method and representation for selectively transmitting 3D point clouds according to user's area of interest, and propose a new 3D Manifesto. By using the proposed technique, it is possible to generate more bitrate images, and it is confirmed that the efficiency of network, decoder, and renderer can be increased while selectively transmitting as needed.

Firefighting officers seems to be vulnerable to musculoskeletal injuries due to their tasks. This study reviewed peer-reviewed articles and aimed to analyze the prevalence of work-related musculoskeletal disorders(WMSDs) among firefighting officers and compare those between domestic and other countries. A total of 1,043 articles was identified through databases including KCI, KISS and PubMed. Upon PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) protocol, 21 articles (domestic:13, foreign: 8) were finally selected for this study. The prevalence of WMSDs among domestic and foreign were 13.4% (median, range 0.8~54.8%) and 20.1% (5.5~71%), respectively. The difference, however, was not statistically significant. It was observed that prevalence was dependent on body parts. Lower back was the highest with 29.2% while arm/elbow was the lowest with 6.3%, indicating lifting heavy objects were related to the prevalence of WMSDs. Further studies are warranted to investigate major causes of WMSDs among firefighting officers and to implement preventive measures for protecting firefighting’s officers from the risks.

포인트 클라우드 콘텐츠는 3D 포인트 집합으로 이루어진 3D 데이터로, 일반적으로 3D 포인트 클라우드는 하나의 객체를 표현하기 위하여 수십, 수백만 개의 3차원 포인트(Point) 데이터가 필요하며, 각 포인트 데이터는 3차원 좌표계의 (x, y, z)좌표와 포인트의 색(color), 반사율(reflectance), 법선벡터(normal) 등과 같은 속성(attribute)으로 구성되어 있다. 따라서 기존 2D 영상보다 한 단계 높은 차원과 다양한 속성으로 구성된 포인트 클라우드를 사용자에게 제공하기 위해서는 고효율의 인코딩/디코딩 기술 연구가 필요하며, 다양한 대역폭, 장치 및 관심 영역에 따라 차별화된 서비스를 제공하기 위한 품질 확장성 기능의 개발이 요구된다. 이에 본 논문에서는 포인트 클라우드 압축에 사용되는 V-PCC에서 3차원 미디어인 포인트 클라우드의 3D 공간 내 포인트 간의 밀도를 변경하여, 새로운 품질 변화를 달성하고 비트전송률 변경을 추가 지원하는 방법을 제시하였다.
