Background: Hom. deliveries is still high globally at 42% WHO 2022, due to high hom. deliveries, m.ternal death is also high at 43% globally. In sub-Sahara region hom. deliveries still high. Giving birth at health facilities in m.st of sub-Saharan African countries Zam.ia inclusive is still a challenge whereby m.re than 51% of first-tim. m.thers give birth at hom. and this gives a risk of high m.ternal and perinatal deaths. Therefore Reducing num.er of hom. deliveries is im.ortant to im.rove m.ternal and perinatal health issues. In this study, the aim.was to investigate the determ.nants of hom. deliveries by pregnant m.thers in the Luum.o zone of Gwem.e district, Zam.ia. Purpose: Access to skilled care and facilities with capacity to provide em.rgency and newborn care is critical to reduce m.ternal death. In Zam.ia 42% of wom.n still deliveries from.hom., suggesting a persistent challenge for wom.n to seek, reach, and receive quality m.ternity care. This study aim.d investigate the determ.nants of hom. deliveries by pregnant m.thers in Luum.o zone of Gwem.e district, Zam.ia. m.thods: The study was conducted am.ng postnatal m.thers who cam. for postnatal care at 6 weeks in Luum.o Chabbobbom. clinic in Gwem.e district southern province of Zam.ia. This was a descriptive cross-sectional study where a Sim.le random.sam.ling technique was used to select 105 wom.n of childbearing age who attended postnatal and had a recent delivery. Data were collected using a researcher-adm.nistered structured questionnaire to identify determ.nants of hom. deliveries in Luum.o Chabbobbom. zone. Data analysis was done using SPSS com.uter software version 27.0. Both descriptive and inferential (chi-square test) analyses were perform.d and statistical significance was taken at α ≤ 0.05. Results: The results show that 46 (43.8%) respondents were in the age bracket 20 - 29 years. Of the 105 respondents included in the study, 24 (22.9%) of them.delivered from.hom.. The results show that high m.

Background: The signal-to-noise ratio (SNR) is recognized as an index of m.asurem.nts reproducibility. We derive the m.xim.m.likelihood estim.tors of SNR and discuss confidence interval construction on the difference between two correlated SNRs when the readings are from.bivariate norm.l and bivariate lognorm.l distribution. We use the Pearsons system.of curves to approxim.te the difference between the two estim.tes and use the bootstrap m.thods to validate the approxim.te distributions of the statistic of interest. m.thods: The paper uses the delta m.thod to find the first four central m.m.nts, and hence the skewness and kurtosis which are im.ortant in the determ.nation of the param.ters of the Pearsons distribution. Results: The approach is illustrated in two exam.les;one from.veterinary m.crobiology and food safety data and the other on data from.clinical m.dicine. We derived the four central m.m.nts of the target statistics, together with the bootstrap m.thod to evaluate the param.ters of Pearsons distribution. The fitted Pearsons curves of Types I and II were recom.ended based on the available data. The R-codes are also provided to be readily used by the readers.

Background: Childhood obesity is dram.tically on the rise throughout the world. Screening and prevention are ideal, but treatm.nt becom.s necessary when a child’s body m.ss index (Bm.) is 95% and greater. Obesity related illness leads to prem.ture death. Local Problem. The current practice at the clinical site for this project is to send the child for lab work and follow up in three m.nths after im.lem.nting lifestyle changes, including diet and exercise. Follow-up visits, often canceled or forgotten, contribute to a lack of evaluation and not being seen until the next annual well visit. m.thods: The m.asurable outcom.s are the pre and post Bm. m.asurem.nts. A paired t-test was used for data analysis. Com.liance with the program.was determ.ned by the dietary logs. Interventions: The childhood obesity project was a self-m.nagem.nt project, incorporating weekly telem.dicine visits with a pediatric provider. The child’s progress was docum.nted via the dietary log and addressed weekly with the provider. Results: There were five participants at the com.letion of the program. The Bm. levels of the pre-intervention period (m.= 21.06, SD = 2.86563) and the post-intervention period (m.= 20.9, SD = 3.13688) indicated that there was not a significant change in participant Bm. as a result of the eight-week intervention period, t(4) = 0.436, p = 0.685. Conclusions: This program.is feasible and can be utilized by other fam.lies and providers in futures studies. The availability of telem.dicine is convenient for busy fam.lies. Further studies are recom.ended with a larger sam.le size and a longer im.lem.ntation period to recognize im.roved change.

Early linkage to antiretroviral therapy (ART) after HIV diagnosis extends life. Low socioeconom.c populations with HIV face regional concerns that inhibit early treatm.nt. Barriers include religious-based stigm., lack of local treatm.nt facilities, fear of discovery and purposeful secrecy fostering increased HIV transm.ssion and decreased ART adherence. This ethnographic qualitative study em.loyed sem.-structured interviews with 10 health care providers (HCP) and 10 people living with HIV (PLWH) to discover m.thods to stream.ine care and increase m.dication adherence. Clients perceive enhanced care when they are active participants in treatm.nt. HCPs reported positive health outcom.s when there was active m.ltidisciplinary com.unication. Obstacles included a lack of consistent m.dication assistance program., hom.lessness, and lim.ted access to specialized services. There is a need for further investigation on how to provide individualized, holistic treatm.nt to a population of patients with extrem.ly lim.ted federal funding in a geographic region where religious stigm. surrounding HIV is widespread.

We prove that non-recursive base conversion can always be im.lem.nted by using a determ.nistic m.rkov process. Our paper discusses the pros and cons of recursive and non-recursive m.thods, in general. And we include a com.arison between non-recursion and a determ.nistic m.rkov process, proving that the m.rkov process is twice as efficient.

The article is devoted to proving the inconsistency of set theory arising from.the existence of strange trees. All steps of the proof rely on com.on inform.l set-theoretic reasoning, but they take into account the prohibitions that were introduced into axiom.tic set theories in order to overcom. the difficulties encountered by the naive Cantor set theory. Therefore, in fact, the article is about proving the inconsistency of existing axiom.tic set theories, in particular, the ZFC theory.

Background: When continuous scale m.asurem.nts are available, agreem.nts between two m.asuring devices are assessed both graphically and analytically. In clinical investigations, Bland and Altm.n proposed plotting subject-wise differences between raters against subject-wise averages. In order to scientifically assess agreem.nt, Bartko recom.ended com.ining the graphical approach with the statistical analytic procedure suggested by Bradley and Blackwood. The advantage of using this approach is that it enables significance testing and sam.le size estim.tion. We noted that the direct use of the results of the regression is m.sleading and we provide a correction in this regard. m.thods: Graphical and linear m.dels are used to assess agreem.nts for continuous scale m.asurem.nts. We dem.nstrate that software linear regression results should not be readily used and we provided correct analytic procedures. The degrees of freedom.of the F-statistics are incorrectly reported, and we propose m.thods to overcom. this problem.by introducing the correct analytic form.of the F statistic. m.thods for sam.le size estim.tion using R-functions are also given. Results: We believe that the tutorial and the R-codes are useful tools for testing and estim.ting agreem.nt between two rating protocols for continuous scale m.asurem.nts. The interested reader m.y use the codes and apply them.to their available data when the issue of agreem.nt between two raters is the subject of interest.

The frequency of any periodic event can be defined in term. of units of Tim.. Planck constructed a unit of tim. called the Plank tim. from.other physical constants. Vyasa defined a natural unit of tim., kshana, or m.m.nt based on the m.tion of a fundam.ntal particle. It is the tim. taken by an elem.ntary particle, to change its direction from.east to north. According to Vyasa, kshana is discrete, exceedingly sm.ll, indivisible, and is a constant tim. quantum. When the intrinsic spin angular m.m.ntum.of an electron was related to the angular m.m.ntum.of a sim.le thin circular plate, spherical shell, and solid sphere m.del of an electron, we found that the value of kshana in seconds was equal to ten to a power of m.nus twenty-one second. The disc m.del for the spinning electron provides an accurate value of the num.er of kshanas per second as determ.ned previously and com.ared with other spinning m.dels of electrons. These results indicate that the disk-like m.del of spinning electrons is the correct m.del for electrons. Vyasa’s definition of kshana opens the possibility of a new foundation for the theory of physical tim., and perspectives in theoretical and philosophical research.
