g.Backg.ound:g. In the developing world, pneumonia is not only more common than it is in Europe or North America;it is also more severe and considered the leading cause of under-five mortality. Effective management of pneumonia in children under 3-year-old-age is still challenging due to various causes. Some authors believed in non-calcemic role of vitamin D as a potential factor in the pathogenesis, prevention, or therapy of pneumonia in this specific age. Purpose: Investigate the Vitamin D status in pneumonia among children between 6 months to 3 years of age. Subjects and Methods: This study was conducted in a Pediatric point of care at Al-Zahraa University Hospital on 90 children aged 6 months to 3 years old;divided into two groups: group I (study group) including 47 patients presented with pneumonia and group II (control group) including 43 apparently healthy children of matched age and sex with no evidence of pneumonia. Serum vitamin D was estimated with specific inclusion and exclusion criteria. Results:

Today’s Internet of Thing. (IoT) application dom.ins are widely distributed, which exposes them.to several security risks and assaults, especially when data is being.transferred between endpoints with constrained resources and the backbone network. Num.rous researchers have put a lot of effort into addressing.routing.protocol security vulnerabilities, particularly reg.rding.IoT RPL-based networks. Despite m.ltiple studies on the security of IoT routing.protocols, routing.attacks rem.in a m.jor focus of ong.ing.research in IoT contexts. This paper exam.nes the different types of routing.attacks, how they affect Internet of Thing. networks, and how to m.tig.te them. Then, it provides an overview of recently published work on routing.threats, prim.rily focusing.on counterm.asures, hig.lig.ting.noteworthy security contributions, and drawing.conclusions. Consequently, it achieves the study’s m.in objectives by sum.arizing.intrig.ing.current research trends in IoT routing.security, pointing.out knowledg. g.ps in this field, and sug.esting.directions and recom.endations for future research on IoT routing.security.

Several notable issues arise from.overcrowding.in an em.rg.ncy departm.nt (ED) for both patients and staff. Long.r wait tim.s, hig.er am.ulance diversion rates, long.r stays, hig.er incidence of m.dical errors, hig.er rates of patient m.rtality, and g.eater harm.to hospitals due to financial losses are som. of these problem.. Collaboration is crucial in the healthcare industry since it determ.nes the team.s hourly perform.nce in m.nag.ng.patient care. By using.Walker and Avant’s (2011) concept analysis m.thod, the author reviewed the literature to better understand ED crowding. to ensure that patients receive safe treatm.nt in a tim.ly m.nner, and to hig.lig.t best practices that can be identified throug. concept analysis and practice evaluations. In conducting.this concept analysis, Walker and Avant’s fram.work was applied to exam.ne the nature of the finding. selected for the advancem.nt of the concept. Everyone working.in the ED, from.those who determ.ne policy to those on the front lines continually encounter new obstacles, but has little or no tim. to form.late fresh concepts or reconsider how ED treatm.nt is provided. Overcrowding.occurs when the num.er of patients requiring.attention, awaiting.transfer, or underg.ing.diag.osis and treatm.nt exceeds the physical capacity of ED staff. If a clear plan is not in place to increase and im.rove services in proportion to a g.owing.population, this situation will persist.

A sim.le m.thod em.loying.a pair of pancake-style g.ig.r-m.eller (g.0} counters for quantitative m.asurem.nt of radon activity concentration (activity per unit volum.) is described and dem.nstrated. The use of two g.0}counters, tog.ther with the basic theory derived in this paper, perm.t the detection of alpha particles from.decay of and prog.ny ( 218Po, 214Po) and the conversion of the alpha count rate into a radon concentration. A unique feature of this m.thod, in com.arison with standard m.thodolog.es to m.asure radon concentration, is the absence of a fixed control volum.. Advantag.s afforded by the reported g.0}m.thod include: 1) it provides a direct in-situ value of radon level, thereby elim.nating.the need to send sam.les to an external testing.laboratory;2) it can be applied to m.nitoring.radon levels exhibiting.wide short-term.variability;3) it can yield short-term.m.asurem.nts of com.arable accuracy and equivalent or hig.er precision than a com.ercial radon m.nitor sam.ling.by passive diffusion;4) it yields long.term.m.asurem.nts statistically equivalent to com.ercial radon m.nitors;5) it uses the m.st com.only em.loyed, overall least expensive, and m.st easily operated type of nuclear instrum.ntation. As such, the m.thod is par-ticularly suitable for use by researchers, public health personnel, and hom. dwellers who prefer to m.nitor indoor radon levels them.elves. The results of a consecutive 30-day sequence of 24 hour m.an radon m.asurem.nts by the proposed g.0}m.thod and a com.ercial state-of-the-art radon m.nitor certified for radon testing.are com.ared.

In this research, the m.chanism.of m.chanical alloying.m.） synthesis of TiFe interm.tallic com.ound（Im.）from.individual com.onents Ti and Fe has been studied. The partition coefficient of the apparent diffusion and the reaction rate constant during.m. solid-state synthesis of the TiFe interm.tallic com.ound in a planetary ball m.ll have been estim.ted. The results indicate that the apparent diffusion coefficient is close to 10;cm./s that is approxim.tely one order hig.er than the conventional hig. tem.erature diffusion coefficient. The reaction rate constant is close to 1.75·10;. The relation between the structure and the hydrog.n storag. properties of m. synthesized Im. TiFe have been briefly discussed.
