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 study was to analyze walking steps to prevent unnecessary energy consuming and prevention of injury from sliding when someone was walking. The questionnaire, high speed video system, E.M.G. system, and force platform system were used to analyze sliding mechanism in biomechanical perspective. Several results were found as following: 1. According to questionnaire regarding sliding, 93.3% of participants have sliding experiences. People have sliding experiences by greasy floor(48.4%) and obstacle (22.5%). Sliding types were found from different kinds of shoes such as sneakers (48.8%) and boots (34.2%). The results were presented as following 44.6% of participants were fall down front direction and 40.3% of people fell down rear side. 2. According to the high speed video system analyzer, step sliding increased with increasing step speed from distance and acceleration speed experiment with 80 steps/min, 100 steps/min, 120 steps/min. Also, the most sliding were occurred with sneakers, boots, and bare feet as order. 3. According to E.M.G. test results, the vastus lateralis M., the vastus medialis m., and the tibialis anterior m. of electric action potential presented strongly when participants fell front, rear, and right side. The vastus lateralis m. and the tibialis anterior m. of electric action potential presented strongly when someone fell left side, but the vastus medialis m. and the gastrocnemius m. of electirc action potential presented as weaker. 4. According to the force platform test results, the most big change of floor antipower of x-axis presented when someone fell the left side. The most of big change of floor antipower of y-axis presented when someone fell down rear side. The most of big change of floor antipower of z-axis presented similarly when someone fell the front, rear, left, and right side.

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 tetrameric STRs loci were studied in a population of Korean(n=223) for allele frequency distribution and applicability to identity and paternity testing, using multiplex PCR with electrophoresis of the PCR products in DNA sequencing gels and subsequent detection of allelic fragments by silver staining. The STRs loci analyzed were HUMCSF1PO, HUMTPOX, and HUMTHO1 ; in the Korean population, 9 alleles with their frequency range of 0.002-0.363 are detected in the HUMCSF1PO, 5 alleles with those of 0.020-1.480 in the HUMTPOX, and 6 alleles with those of 0.002-0.489 in the HUMTHO1. The highest observed heterozygosity is found at the locus HUMCSF1PO(0.709), those of the loci HUMTPOX and HUMTHO1 being 0.646 and 0.632, respectively. All loci meet Hardy-Weinberg expectations ; there are good agreement between the observed and expected values under Hardy-Weinberg equilibrium. Moreover, pairwise comparisons between loci show allelic independence for all the 3 loci comparisons. The power of discrimination (PD) determined for the locus HUMCSF1PO is 0.8896 (88.96%), that of the HUMTPOX is 0.8818(88.18%), and that for the HUMTHO1 is 0.8367(83.67%) ; the combined power of discrimination for the triplex is 0.9976(99.76%). The power of exclusion(PEX) calculated for the loci HUMCSF1PO, HUMTPOX, and HUMTHO1, being prior probability that a falsely accused father will be excluded, and 0.5173(51.73%), 0.4610(46.10%), and 0.5101(510.01%), respectively, and the cummulative power of exclusion(CPE) for all the three loci is 0.8726(87.26%). Thus, these allelic frequency data can be used to construct the database of the multiplex PCR-based DNA profile in the Korean population. The calculated parameter, "power of discrimination(PD)" and "power of exclusion(PEX)", show the informativeness of these loci for the determination of identity and relatedness of individuals.
