Published: October 2021

This study aimed to determine the relationship of sleep quality with the percentage of body fat in children (ages 9-12 years) in the Elementary School Complex of IKIP I Makassar. The study used the Analytical Survey design with a cross-sectional approach. The researcher will compare the causes and consequences variables simultaneously and explain the relationship between the research variables through hypothesis testing. This study uses quantitative methods, namely through assessing sleep quality and body fat percentage using a questionnaire. The data was collected through in-depth interviews and observations of children. Sampling uses purposive sampling and data analysis using the Chi-Square test. The results of the study showed that there was no significant relationship between sleep quality and body fat percentage. However, after being tested based on the components of sleep quality, it was seen that good sleep quality and poor sleep quality in component 3 (sleep duration). Moreover, component 4 (daily sleep efficiency) had a significant relationship between sleep duration and daily sleep efficiency with body fat percentage. Recommendations from this research are needed on the relationship between sleep quality and student achievement index.

ABSTRACT.
In this pilot comparative study, we investigated and compared the effects of existing vector control tools on sandfly densities and mortality to inform and support the National Kala-azar Elimination Program (NKEP). The interventions included insecticidal wall painting (IWP), reduced-coverage insecticidal durable wall lining (DWL), insecticide-impregnated bednets (ITN), and indoor residual spraying with deltamethrin (IRS). Sakhua union with seven villages was the study area, which was the most highly endemic visceral leishmaniasis union in Trishal upazila, Bangladesh. Each cluster containing the different interventions included approximately 50 households. Study methods included random selection of clusters, collection of sandfly by CDC light trap and manual aspirator to determine sandfly density, and sandfly mortality determined by WHO cone bioassay test. Trained field research assistants interviewed household heads using structured questionnaires for sociodemographic information, as well as safety and acceptability of the interventions. Descriptive and analytical statistical methods measured interventions’ effect and its duration on sandfly density reduction and mortality. We measured the relative efficacy of IWP on sandfly control against DWL, ITN, and IRS by the difference-in-difference regression model. We found that existing interventions were effective and safe for sandfly control with different duration of effect and acceptability. The relative efficacy of IWP for sandfly reduction varied by –59% to –91%, –75% to –81%, and –30% to –104% compared with DWL, ITN, and IRS, respectively, at different time points during the 12-month follow-up. These study results will guide the NKEP for selection of sandfly control tool(s) in its subsequent consolidation and maintenance phases.

ABSTRACT.
Magnetic resonance images from 197 patients with calcified neurocysticercosis (NCC), 38 with viable NCC and 197 NCC-free healthy rural villagers were evaluated to compare the frequency of hippocampal atrophy/sclerosis (HAS) across these populations. Scheltens’ medial temporal atrophy scale was used for hippocampal rating. The median age of the 432 study participants was 46 years (interquartile range, 29–62 years), and 58% were women. Hippocampal atrophy/sclerosis was disclosed in 26.9% patients with calcified NCC, compared with 7.9% in patients with viable NCC and 8.1% in healthy rural villagers. After adjusting for age, gender, and history of epilepsy, hippocampal atrophy/sclerosis was more frequent in patients with calcified NCC than in those with viable cysts (RR, 3.60; 95% CI, 1.18– 0.99; P = 0.025) and healthy rural villagers (RR, 3.43; 95% CI, 1.94–6.06; P < 0.001), suggesting that hippocampal damage develops late in the course of this parasitic disease.

ABSTRACT. This study was focused on investigation of amount of macro and trace metals present in the fruit samples of Rubus steudneri Schweinf plant and its underlying soil samples collected from Chencha, Dega Damot and Fiche areas of Ethiopia. The levels of selected metals (K, Ca, Mg, Fe, Mn, Zn, Cu, Cd, and Pb) were determined by microwave plasma-atomic emission spectroscopy using wet-digestion technique. The validity of the method was checked by the analysis of spiked samples whose recovery was found in the range of 90.5-108%. The mean concentration of metals K, Mg, Fe, Ca, Zn, Cu, Mn, Pb and Cd in the fruit samples were found in the range of 9463-9836, 973-1099, 328-639, 2663-2999, 29.6-52.8, 6.70-8.87, 128-639, 2.54-3.37 and 0.26-1.21 mg/kg, respectively. The level of metals in the soil samples were found in the range of 1375-1790, 1169-1388, 74951-104145, 2079-3502, 122-149, 21.6-40.4, 1359-1931, 7.11-17.0 and ND mg/kg, respectively. The accumulation factor values for the tested metals were found in the range of 0.003 (Fe) - 7.07 (K). The Rubus steudneri Schweinf fruit is good source of essential metals and useful to human health. However, the concentration of toxic metals viz. Cd and Pb were found in amount excess as compared to WHO/FAO maximum permissible limit.

ABSTRACT. Creatinine biomolecule has three different coordination modes through the (exocyclic O(5) and ring N(1)), (imine N(2) and ring N(1)) or as monodentate ligand via exocyclic O(1)). The FTIR and electronic spectra of the synthesized manganese(II), iron(III), chromium(III), and cobalt(II) complexes consistent with the coordinated behavioral derived from the structural analyses. Thermogravimetric data agree with the stoichiometry and proposed formulas [Mn(C4H7N3O)2(Cl)2]4H2O, [Fe(C4H7N3O)2(Cl)2]Cl.6H2O, [Cr(C4H7N3O)2(Cl)2]Cl.6H2O, and [Co(C4H7N3O)2(Cl)2]6H2O. Four new transition metal complexes derived from the reaction of creatinine chelate and metal salt (MnCl2.4H2O, FeCl3.6H2O, CrCl3.6H2O, and CoCl2.6H2O), were prepared with 1:2 (metal: ligand) stoichiometry, isolated and well characterized by a different spectral and analytical techniques including FTIR, UV/Vis, magnetic susceptibility, molar conductance, elemental analysis, and TGA/DrTGA/DTA. The solid complexes were formed with the binding of the creatinine ligand through exocyclic O(5) and ring N(1) and presented as an octahedral geometry. In addition molecular docking calculations have been performed between complexes of manganese(II), iron(III), chromium(III) and cobalt(II) with creatinine biomolecule ligand with the Covid-19 protease (6LU7) to determine the best binding site and its inhibitory effect.

ABSTRACT. The kinetics and mechanistic steps to the electron transfer reaction of the peroxo-bridged binuclear cobalt(III) complex of succinimide [(suc)(en)2Co(O2)Co(en)2(suc)2+] hereafter called peroxo-bridged dicobalt(III) complex ‘[Co(O2)Co2+]’ by glycine have been carried out spectrophotometrically at λ = 420 nm and T = 26 ± 1 oC, [H+] = 1 x 10-3 M and ᶙ = 0.5 M (NaCl) in aqueous acidic medium. The reaction was found to be first order with respect to [Co(O2)Co2+] and [(Gly] and experimental data indicates a second-order overall. The reactions obeyed the general rate law: (d[Co(O2)Co2+]/dt) = (a +b)[H+])[Co(O2)Co2+][Gly]. Varying hydrogen ion concentration accelerated the reaction rate and shows first-order dependence while the reactions also affected by changes in the ionic strength of the reaction medium by giving a non-negative salt effect in the course of the reaction. Free radicals were not detected in the reactions. Spectroscopic investigation and Michaelis-Menten plots suggest the absence of intermediate complex formation. The experimental result obtained in this system is concluded in favor of the outer-sphere mechanism.

ABSTRACT. In the present research, three zinc(II) complexes were synthesized using 3-(3-fluorophenyl)-2-methylacrylic acid (HL), 1,10-phenanthroline and 2,2'-pyridine as ligands. The composition, structural confirmation, coordination way of ligand and assignment of geometry to the complexes were made by different analytical tools like elemental analysis, FTIR and 1H-NMR. The ligand 3-(3-fluorophenyl)-2-methylacrylate appeared to coordinate the metal (Zn) atom via COO- moiety in all of the complexes (1-3) while 1,10-phenanthroline and 2,2'-pyridine co-ordinated to Zn(II) atom through N-donor sites in complexes 2 and 3, respectively. The complex 1 showed four while 2 and 3 showed six co-ordinated geometry. The synthesized complexes were evaluated for antimicrobial and cytotoxic activities. The obtained results showed that complexes are active against microbial agents and exhibited significant cytotoxicity.

Published: October 2021

O lean construction tem como um de seus objetivos eliminar as perdas na construção civil. Este trabalho busca identificar e analisar as causas, impactos e ocorrências de três tipos de perda, além de verificar a veracidade da relação de causa-efeito que elas possuem entre si. O making-do ocorre quando não estão disponíveis todos os pré-requisitos para o início de alguma atividade, necessitando de uma improvisação para prosseguir o serviço. O retrabalho consiste na correção de uma atividade que foi executada com falhas. A falta de terminalidade acontece quando uma atividade é dada como finalizada, porém são deixados pontos de inconclusão do serviço. Assim, foi feito um Estudo de Caso em uma obra de edificação residencial em Fortaleza. Mão de obra, gestão inadequada e atividades interdependentes foram as causas mais recorrentes no estudo. Já os impactos foram redução da qualidade do serviço, diminuição da produtividade, e perda de material. Identificou-se eventos onde existia uma relação de causa-efeito entre elas, mas ainda necessita-se de estudos que reforcem a sua recorrência, pois eles não podem ser dissociados das circunstâncias onde ocorreram.

Published: October 2021

Purpose: The purpose of the study was to investigate the contributors associated with having a home delivery after antenatal hospital care visits in women of reproductive age in Narok South Sub-County, Kenya.
Materials and Methods: Across-sectional survey of 323 women who delivered at home within the last two years yet attended antenatal care clinics was carried out. The survey was conducted in Narok south sub-county, and respondents were picked randomly from all the wards. Data was collected using an interviewer-administered questionnaire; exploration of variables was done using a chi-squire test. Using odd ratio with95% confidence interval with p<0.05 taken as a statistically significant association.
Results: The One way ANOVA analysis indicated that there was a significant influence on source of income and home delivery (F=62.022, P=0.0001. All three factors (age, education, distance) had a significant positive relationship with the number of children delivered at home(r =0.574, 0.677 and 0.534 respectively). Using Pearson correlation analysis, the findings revealed that the distance to the health facility significantly influenced home delivery(r=0.53, P=0.0001).On assessing the level of knowledge associated with home delivery, many mothers were aware of bleeding and perinea tears as complications. Given opportunity majority would not deliver at home again (77.4%). Those who had no emergency backup plan were96.3% and those who stated that they would deliver at home again, had no emergency backup plan. In contrast, women who had emergency backup plans would not deliver at home again (Fishers' exact test = 3.628, P = 0.043). Awareness of the risk factors stated 95.0% were aware of the risk of placenta praevia and bleeding problems, and there was no significant difference in the number of women aware of the danger signs to those not familiar (x2 value 30000,p-value 0.224).
Unique contribution to theory, practice and policy: The study recommended that the County Education officers in liaison with social development officers should promote adult formal education to improve literacy levels, which will go a long way in influencing reproductive health decisions. County health management team, together with the reproductive health section should network with other relevant stakeholders to increase sensitization on utilization of hospital-based deliveries.
Identifying sensitivities in flood frequency analyses using a stochastic hydrologic modeling system

Published: October 2021

Abstract. This study employs a stochastic hydrologic modeling framework to evaluate the sensitivity of flood frequency analyses to different components of the hydrologic modeling chain. The major components of the stochastic hydrologic modeling chain, including model structure, model parameter estimation, initial conditions, and precipitation inputs were examined across return periods from 2 to 100 000 years at two watersheds
representing different hydroclimates across the western USA. A total of 10 hydrologic model structures were configured, calibrated, and run within the Framework for Understanding Structural Errors (FUSE) modular modeling
framework for each of the two watersheds. Model parameters and initial
conditions were derived from long-term calibrated simulations using a
100 member historical meteorology ensemble. A stochastic event-based
hydrologic modeling workflow was developed using the calibrated models in
which millions of flood event simulations were performed for each basin. The analysis of variance method was then used to quantify the relative
contributions of model structure, model parameters, initial conditions, and
precipitation inputs to flood magnitudes for different return periods.
Results demonstrate that different components of the modeling chain have
different sensitivities for different return periods. Precipitation inputs
contribute most to the variance of rare floods, while initial conditions are
most influential for more frequent events. However, the hydrological model
structure and structure–parameter interactions together play an equally
important role in specific cases, depending on the basin characteristics and type of flood metric of interest. This study highlights the importance of critically assessing model underpinnings, understanding flood generation
processes, and selecting appropriate hydrological models that are consistent with our understanding of flood generation processes.

Authors: Sabando Christian M. , Alo Evangeline B. 
Published: October 2021

Higher educational institutions are responsible for integrating the vital aspect of primary healthcare services in school settings. The study assessed the quality and utilization of school health services (SHS) of a state university in the Philippines. A descriptive-comparative and correlational study was utilized through a researcher-made questionnaire among 310 respondents using stratified random sampling. Generally, findings revealed that the level of quality of SHS is high, and the extent of utilization is great. It showed significant differences in the level of quality when grouped as to geographic clusters and the extent of utilization when grouped as to designation and geographic clusters. There is a positive correlation between the level of quality and the extent of utilization of SHS. Challenges encountered were the limited availability of health personnel and inadequate health supplies and equipment. Therefore, the higher the quality of SHS, the greater is the extent of utilization towards building a healthy university.

A New Explanation of Christological Origins: A Review of the Work of Larry W. Hurtado
Authors: Fletcher-Louis Crispin H.T. 
Published: October 2021

Prof. Larry Hurtado’s three-volume work on christological origins has advanced understanding in several key respects and his account is simpler than that of his predecessors. However, it remains an evolutionary, multi-stage model and it is historically problematic. He overstates the case for Jewish opposition to Christ-devotion, minimises the ethical particularity of earliest Christianity and the model suffers some serious internal tensions. His claim that religious experiences gave the decisive impetus to Christ-devotion does not reckon adequately with the implications of social-science study, is not supported by the primary texts and conflicts with the important evidence that visionary and mystical practices were frowned upon in some early Christian quarters. Hurtado presents his work as theologically disinterested. However, he endorses Lessing’s radical separation of theology and history and this theologically loaded judgement seems to be reflected in the non-incarnational character of the Christology Hurtado describes.
The Markan Narrative’s Use of the Old Greek Text of Jeremiah to Explain Israel’s Obduracy
Authors: Perkins Larry 
Published: October 2021

A close reading of the Septuagint (LXX) translation of Jeremiah in conjunction with a careful examination of Markan contexts where Jeremiah materials occur reveals that Jeremiah’s prophetic message influences the Markan portrayal of Jesus’ words and deeds, especially to explain Israel’s obduracy. By examining specific contexts in Mark’s narrative (chs. 8, 11, 13, 14) where potential intertextual linkages with the Greek version of Jeremiah’s prophecy occur I demonstrate the potential contribution of the Greek version of Jeremiah’s material to our understanding of Mark’s purpose. His use of Jeremiah material seems to focus almost exclusively on aspects of opposition that Jesus experienced. The general theme of Israel’s obduracy, illustrated by the temple cleansing incident, the parable of the tenant farmers, and the prophecy about the destruction of Jerusalem and the temple seems to provide the thread that the Markan author finds useful to link with Jeremiah’s message.
