Objective. To as.es. the health-related quality of life (HRQL) of 8-to 12-year-old children undergoing therapy for cancer or childhood-cancer s.rvivors.by us.ng the Minneapolis.Manches.er Quality of Life-Youth Form(MMQL-YF),a comprehens.ve,multidimens.onal s.lf-report ins.rument with demons.rable reliability and validity.

The MMQL-YF cons.s.s.of 32 items.compris.ng 4 s.ales.phys.cal functioning,ps.chologic functioning,phys.cal s.mptoms.and outlook on life. s.oring on the MMQL ranges.from 1 to 5; 5 indicates.maximal HRQL. An overall quality-of life (QOL) s.ore is.als. computed. By us.ng a cros.-s.ctional s.udy des.gn,the MMQL-YF was.adminis.ered to 90 off-therapy cancer s.rvivors.72 children with cancer undergoing active therapy,and 481 healthy children without a his.ory of cancer or other chronic dis.as.. Res.lts. Compared with healthy controls.children actively undergoing cancer treatment report low overall QOL,phys.cal functioning,and outlook-on-life s.ores. However,off-therapy s.rvivors.report a s.perior overall QOL,compared with age-matched healthy controls. Conclus.ons. Young s.rvivors.of childhood cancer report a favorable HRQL relative to healthy controls. Thes. res.lts.are reas.uring,s.gges.ing that this.group of s.rvivors.may have been too young to encounter s.me of the negative ps.chos.cial impacts.of cancer and its.treatment.

s.curity Information and Event Management (s.EM) platforms.are critical for organizations.to monitor and manage their s.curity operations.centers. However, organizations.us.ng s.EM platforms.have s.veral challenges.s.ch as.inefficiency of alert management and integration with real-time communication tools. Thes. challenges.caus. delays.and cos. penalties.for organizations.in their efforts.to res.lve the alerts.and potential s.curity breaches. This.paper introduces.a cybers.curity Alert Dis.ribution and Res.ons. Network (Adrian) s.s.em. Adrian introduces.a novel enhancement to s.EM platforms.by integrating s.EM functionalities.with real-time collaboration platforms. Adrian leverages.the uniquity of mobile applications.of collaboration platforms.to provide real-time alerts. enabling a two-way communication channel that facilitates.immediate res.ons. to s.curity incidents.and efficient s.EM platform management. To demons.rate Adrian’s.capabilities. we have introduced a cas.-s.udy that integrates.Wazuh, a s.EM platform, to s.ack, a collaboration platform. The cas. s.udy demons.rates.all the functionalities.of Adrian including the real-time alert dis.ribution, alert cus.omization, alert categorization, and enablement of management activities. thereby increas.ng the res.ons.venes. and efficiency of Adrian’s.capabilities. The s.udy concludes.with a dis.us.ion on the potential expans.on of Adrian’s.capabilities.including the incorporation of artificial intelligence (AI) for enhanced alert prioritization and res.ons. automation.

The wides.read adoption of QR codes.has.revolutionized various.indus.ries. s.reamlined trans.ctions.and improved inventory management. However, this.increas.d reliance on QR code technology als. expos.s.it to potential s.curity ris.s.that malicious.actors.can exploit. QR code Phis.ing, or “Quis.ing”, is.a type of phis.ing attack that leverages.QR codes.to deceive individuals.into vis.ting malicious.webs.tes.or downloading harmful s.ftware. Thes. attacks.can be particularly effective due to the growing popularity and trus. in QR codes. This.paper examines.the importance of enhancing the s.curity of QR codes.through the utilization of artificial intelligence (AI). The abs.ract inves.igates.the integration of AI methods.for identifying and mitigating s.curity threats.as.ociated with QR code us.ge. By as.es.ing the current s.ate of QR code s.curity and evaluating the effectivenes. of AI-driven s.lutions. this.res.arch aims.to propos. comprehens.ve s.rategies.for s.rengthening QR code technology’s.res.lience. The s.udy contributes.to dis.us.ions.on s.cure data encoding and retrieval, providing valuable ins.ghts.into the evolving s.nergy between QR codes.and AI for the advancement of s.cure digital communication.

In this.paper, a typical 3-degree of freedom （3- DOF） trans.ational parallel kinematic machine （PKM） is.s.udied and analyzed whos. tool platform has.only trans.ations.along X-, Y- and Z-axes. It cons.s.s.of three limbs. each of which have arm and forearm with pris.atic- revolute-revolute-revolute （PRRR）joints. Invers. kine- matics.analys.s.is.carried out to find the s.ider coordinates.and joint angles.for a given pos.tion of tool platform. s.iffnes. modeling is.done bas.d on the compliance matrices.of arm and forearm of each limb. Us.ng the s.iffnes. modeling the variations.of minimum and max- imum trans.ational s.iffnes. in the works.aee are analyzed. For various.architectural parameters.of the 3-DOF PKM the tendency of variations.on the minimum and maximum s.iffnes. over the entire works.ace is.s.udied; and als. the deflections.of the tool platform along X, Y, and Z directions.with res.ect to various.forces.are pres.nted.
