Slawomir Kukliński,Lechosław Tomaszews,Robert Kołakowski,Prosper Chemouil 한국통신학회 2021 Journal of communications and networks Vol.23 No.6

Network slicing is a relatively recent paradigmthat has become a subject of intensive research. Most of theexisting approaches follow the ETSI NFV MANO model withsome extensions related to multi-domain slicing, slice selection,etc. The framework is a part of the standalone variant ofthe 5G network standardized by 3GPP. However, the currentimplementation of network slicing in 5G has several limitations,especially regarding management and orchestration: The isolationof slice management is not appropriately addressed, the slicetenant management capabilities are limited, and the managementand orchestration centralization raises serious scalability andreliability issues. Moreover, the slice-level operations are notwell-separated from other processes due to a lack of properseparation of concerns. As a result, the overall network slicingarchitecture has complex interactions with many components ofthe 5G network. In this paper, we describe a new framework thatuses an approach to sustain self-managed and self-orchestratedslices. To that end, we propose a modular architecture in whichslices have embedded (in-slice) management and orchestrationsupport, and multi-domain slices rely on multiple slice-agnosticorchestrators. The framework enables the composition of newslices as a combination of single domain-slices in a relativelyeasy, technology-independent manner.

The purpose of this paper is to select 7 male athletes and female athletes of high school, and to compare their active potential differences of upper arm muscles according to characteristic of a racket. the results obtained are as follows: 1. According to the accumulative distribution rate of racket material, graphite and wood material show better efficiency in case of brachio radialis muscle of male athletes, but the racket material shows no constant efficiency in brachii radialis muscle of female athletes. In case of flexor carpi radialis muscle, wood material provides better efficiency only for male athletes. In case of triceps brachii muscle, wood material gives better efficiency to males athletes and steel material gives better efficiency to females athletes. Especially in case of biceps brachii muscle, neither male nor female athletes are influenced by racket materials at impact. 2. In the muscle load rate according to racket material, wood has the highest muscle active potential and graphite has the lowest active potential. Therefore, graphite is thoght to be better in the efficiency of muscle load rate.

The purpose of this study was to examine the kinematic changes of the body according to various weight loads and the holding during carrying object. The experiments were conducted with utilizing image, analyses for five male and five female adults as subjects. The results were as followed. 1. Meaningful differences were shown partially in the angle changes of the subject's wrist joints, elbow joints and coxal articulations, but not in the angle changes of the subject's knee joints, according to the types of holding the objects while subjects carrying 5kg objects. So, carrying a light object of 5kg in workplaces or gyms doesn't have much influence on human joints and muscles. 2. Meaningful differences of angle changes were shown between right holding and vertical holding while subjects carrying 10kg objects. Female subjects had difficulties to hold the angles of their wrist joints and elbow joints, carrying 10kg objects, because the first loads were imposed on their wrists and female has weaker muscles than male. In right holding of 10kg objects, female subjects had backward body centers from their bodies, the angle of their coxal articulation became bigger and they had unstable behaviors. 3. Female subjects had wider angle of their wrist joints and elbow joints while carrying 15kg objects than male subjects. But male subjects had bigger angle of coxal articulation than female subjects. Because female has weaker muscles, female subjects couldn't maintain the angles of their wrist joints and elbow joints. 4. The 20kg objects influenced the angles of the wrist joints, the elbow joints and the coaxal articulations of both sex subjects in any type of holding during their carrying 20 kg objects, but didn't influence their knee joints. 5. in carrying 25kg objects, female subjects had wider angles of their wrist joints, elbow joints and knee joints in each holding type than male subjects and the significant difference were shown according to the holding type. But in the case of coxal articulation, male subjects had the bigger angles and meaningful differences. This comes from the weakness of female's muscle. N\Male subject's upper bodies were drawn back and the objects influenced their wrists more than their arms.
