Maternal Satisfaction on Delivery Service and Its Associated Factors in Public Health Facilities at West Shewa Zone, Ethiopia

Background Maternal delivery satisfaction could be assessed to improve the quality and effectiveness. Thus, this study aimed to assess maternal satisfaction with delivery services and associated factors in public health facilities in West Shewa Zone, Ethiopia. Methods An institution-based cross-sectional study was conducted on maternal satisfaction delivery services. Systematic and stratified sampling techniques were used to select mothers by using their delivery registration number and to select health facilities. A binary logistic regression model was used to identify associated factors. Results Among mothers, the overall satisfaction with delivery service was 584 (87%). Shower service availability (39.8%), toilet cleanliness (32.6%), and waiting area cleanliness (31.1%) were significant areas of mothers' dissatisfaction with delivery services. Uneducated mothers, mothers of 1–6 education level, monthly income of mothers less than 500 Birr, mothers who followed antenatal care, mothers who had actual fetal outcome, mothers who admitted from 6:00 AM to 12:00, and mothers who admitted from 12:00 AM to 6:00 PM were satisfied with delivery services. Conclusion The age of the mother, mother's education level, monthly income of mother, antenatal care, fetal outcome, place of delivery, and admission time of the mother were significantly associated factors for mothers' satisfaction with delivery services. Therefore, regional health bureaus and zonal health offices should work collaboratively on maternal care to improve maternal satisfaction during delivery.
Is Having a Computer or Internet Available in the House Effective in Improving Performance in Mathematics or Spanish?

Following the increased popularity of computers and internet among students, this paper studies the relationship between computer and internet usage at home on students mathematics and Spanish test scores using the PROSPERA evaluation dataset. It also investigates how this effect varies across different income groups and over time. Overall, having computer and internet at home will have a positive and negative effect on test scores, respectively, and that having both computer together with internet at home will bring additional positive effects on students test scores. In addition, these effects will converge towards zero over time, and the impact of internet and computer with internet is more significant for lower socio-economic groups, whereas that of computer is more significant for mid-income households. Our value-added regression shows that the impact of computer, internet, and computer with internet on test scores will all be insignificant except for the negative correlation between internet and Spanish test score. The students family backgrounds and their study efforts appeared to be important determinants of test scores, with the fathers education being a more important factor than that of the mothers for richer households, and vice versa.
Comparison of Machine Learning Models and the Fatty Liver Index in Predicting Lean Fatty Liver

The reported prevalence of non-alcoholic fatty liver disease in studies of lean individuals ranges from 7.6% to 19.3%. The aim of the study was to develop machine-learning models for the prediction of fatty liver disease in lean individuals. The present retrospective study included 12,191 lean subjects with a body mass index < 23 kg/m2 who had undergone a health checkup from January 2009 to January 2019. Participants were divided into a training (70%, 8533 subjects) and a testing group (30%, 3568 subjects). A total of 27 clinical features were analyzed, except for medical history and history of alcohol or tobacco consumption. Among the 12,191 lean individuals included in the present study, 741 (6.1%) had fatty liver. The machine learning model comprising a two-class neural network using 10 features had the highest area under the receiver operating characteristic curve (AUROC) value (0.885) among all other algorithms. When applied to the testing group, we found the two-class neural network exhibited a slightly higher AUROC value for predicting fatty liver (0.868, 0.841–0.894) compared to the fatty liver index (FLI; 0.852, 0.824–0.81). In conclusion, the two-class neural network had greater predictive value for fatty liver than the FLI in lean individuals.
An optimal integral sliding mode control strategy based on a pseudospectral method for a class of affine systems

This paper presents an optimal integral sliding mode control method based on a pseudospectral method for a class of affine systems with state and control constraints. First, a general form of an integral sliding mode is presented. Integral sliding mode control cannot deal with the problem of states and control constraints, nor can it satisfy the minimization of the cost function. The pseudospectral method has a high convergence speed and performs well in solving optimal control problems with general performance index, endpoint conditions and path constraints. In consideration of these advantages, an optimal integral sliding mode controller is determined by the pseudospectral method. Then, the stability analysis of optimal pseudospectral sliding mode method is discussed. Finally, numerical simulations show the effectiveness of the proposed method. An application example, consisting of an overhead crane system, is investigated to demonstrate the effectiveness and robustness of the proposed technique.

Controlling Air Vortex in Air-Vortex Spinning by Zeng-He Model

Using Zeng-He model, we present a simple analytical formulation for the forces that determine the strength of the air vortex twist acting on the yarns during air-vortex spinning as a function of nozzle pressure, flow rate, the radius of the main nozzle in the horizontal plane, nozzle pressure, jet orifice angle, the number of the orifices, jet orifice angle, diameter of the jet orifice, and the distance from the top of the twisting chamber to the spindle. Comparison with the numerical results shows the effectiveness and convenience of the model.
Impact of the Cold Pool on Mesoscale Convective System–Produced Extreme Rainfall over Southeastern South Korea: 7 July 2009

AbstractIn this study, an extreme rainfall-producing quasi-stationary mesoscale convective system (MCS) associated with the Changma front in southeastern South Korea is investigated using numerical simulations and sensitivity tests. A record-breaking rainfall amount was recorded in response to repeated initiation of new cells (i.e., back-building) over the same area for several hours. The aim of this study is to realistically simulate and analyze this extreme rainfall event to better understand an impact of the cold pool that leads to the quasi-stationary MCS over southeastern South Korea by using a convection-allowing-resolution (2 km) nonhydrostatic atmospheric model.The control experiment (CNTL) was successfully performed, yielding the quasi-stationary, back-building MCS at approximately the correct location and time. In the CNTL run, diabatic cooling due to evaporation of raindrops was responsible for the formation of the cold pool. The development of the cold pool was responsible for the deceleration.

Primary Healthcare Pharmacists’ Perceived Organizational Support and Turnover Intention: Do Gender Differences Exist?

Purpose This study aims to explore the relationship between the four-dimensional structured perceived organizational support (emotional support, instrumental support, supervisor support, and coworker support) and the turnover intention of pharmacists in primary healthcare institutions. The gender differences between perceived organizational support and turnover intention will also be examined. Methods A cross-sectional study was conducted in primary healthcare institutions of 31 cities in China from 2 July to 1 September 2021. And the binary logistic regression model was employed for data analysis. Results 937 valid questionnaires are allocated from pharmacists in primary healthcare institutions. The regression results indicated that emotional support (b=0.073, p<0.001) has a significant influence on pharmacists’ turnover intention, and the effect of supervisor support (b=0.173, p=0.046) on pharmacists’ turnover intention differs by gender. Conclusion These findings offer suggestions for the management and stabilization of pharmacists in primary healthcare institutions. It is suggested that specific measures should be taken to increase pharmacists’ perceived organizational support and reduce their turnover intention. At the same time, gender differences need to be taken into consideration by the managers when providing perceived organizational support to reduce their turnover intention through adaptive management.
Chemodynamical Simulations of the Milky Way Galaxy - Inhomogeneous Chemical Enrichment

Abstract The predictions of our chemodynamical simulations from cosmological initial conditions are as follows: The disk formed Inside-out. Metallicity radial and vertical gradients exist, but no [α/Fe] radial gradient. Metallicity radial gradient is steeper at higher redshifts. The [α/Fe]-[Fe/H] relation is caused by the delayed enrichment of Type Ia supernovae (not with long lifetimes, but with the metallicity effect). The bulge formed through the assembly of small gas-rich galaxies at high redshifts. [α/Fe] is higher, [Mn/Fe] is lower, [(Na, Al)/Fe] are higher than the disk. Metallicity and [α/Fe] vertical gradients exist, which is caused by the increase of metal-rich and low [α/Fe] populations at lower latitudes. Bars may form later, which may show boxy and cylindrical rotation. Half of thick disk stars (kinetically selected) come from minor mergers. [α/Fe] is higher, and [Mn/Fe] is lower than the thin disk, but [(Na, Al, Cu, Zn)/Fe] are lower than the bulge. There are metallicity vertical, weak metallicity radial, and no [α/Fe] radial gradients. It would be interesting to compare the predictions with other models such as radial mixing, disk heating, and clumpy disks. For the solar neighborhood, the frequency distributions of elements from oxygen to zinc are in excellent agreement not only for the average values but also for the scatter. In chemodynamical simulations, chemical enrichment takes place inhomogeneously, and the scatter originates from a combination of various effects - mergers, migration, and in-situ. The inhomogeneous enrichment is important in reproducing observed nitrogen abundances, and also in understanding elemental abundance patterns of dwarf spheroidal galaxies and carbon-enhanced damped Lyman α systems.
Human Chorionic Gonadotropin Regulates the Smad Signaling Pathway by Antagonizing TGF-β in Giant Cell Tumor of Bone

Background: Giant cell tumor of bone (GCTB) is a locally aggressive bone tumour aggravated by stromal cell proliferation and metastasis. Objective: We investigated the mechanism of action of human chorionic gonadotropin (HCG) in mediating GCTB proliferation and invasion. Methods: The expression of HCG was quantified using quantitative real-time PCR. After the primary stromal cells were isolated and identified, the function of HCG in GCTB was estimated using the cell counting kit-8, flow cytometry, scratch experiment, transwell assay, Western blot, and immunofluorescence. Moreover, the mechanism of HCG was assessed through western blotting. Results: HCG expression was decreased in clinical tissue samples from patients with GCTB. We validated that HCG repressed stromal cell proliferation, migration, invasion, autophagy, and epithelial-mesenchymal transition (EMT) and promoted cell apoptosis in GCTB. We also verified that HCG repressed the autophagy and EMT of stromal cells through the Smad signaling axis in GCTB. HCG inhibited the transduction of the Smad signaling pathway by restraining the binding of the TGF-β II receptor to ligand Activin A. Conclusion: HCG restrained the Smad signaling pathway by antagonizing TGF-β signaling in GCTB. HCG may serve as a useful patent to treat GCTB.

Nondegeneracy of solutions to the critical p$p$ ‐Laplace Kirchhoff equation

We establish the nondegeneracy of solutions in suitable space to the following p$p$ ‐Laplace Kirchhoff equation with critical Sobolev exponent: −1+b∫RN|∇u|pdxdiv(|∇u|p−2∇u)=up*−1,u>0inRN,$$\begin{eqnarray*} &&\hspace*{80pt} -{\left(1+b\int _{\mathbb {R}^N}|\nabla u|^p dx\right)} {\rm div}(|\nabla u|^{p-2}\nabla u)=u^{p^\ast -1},\hspace*{-80pt}\\ &&\hspace*{80pt} u>0\quad \mbox{in}\quad \mathbb {R}^N,\hspace*{-80pt} \end{eqnarray*}$$where b>0$b>0$ , 12p$N>2p$ , that is, we show that there exist two nondegenerate solutions that seem to be completely different from the result of critical p$p$ ‐Laplace equation ( b=0$b=0$ ) or the low‐dimensional Kirchhoff equation (the case p
Omphalocele and Cardiac Abnormalities—The Importance of the Association

Omphalocele is the most common ventral abdominal wall defect. Omphalocele is associated with other significant anomalies in up to 80% of cases, among which the cardiac ones are the most frequent. The aim of our paper is to highlight, through a review of the literature, the importance and frequency of association between the two malformations and what impact this association has on the management and evolution of patients with these pathologies. We reviewed the titles, the available abstracts, and the full texts of 244 papers from the last 23 years, from three medical databases, to extract data for our review. Due to the frequent association of the two malformations and the unfavorable effect of the major cardiac anomaly on the prognosis of the newborn, the electrocardiogram and echocardiography must be included in the first postnatal investigations. The timing of surgery for abdominal wall defect closure is mostly dictated by the cardiac defect severity, and usually the cardiac defect takes priority. After the cardiac defect is medically stabilized or surgically repaired, the omphalocele reduction and closure of the abdominal defect are performed in a more controlled setting, with improved outcomes. Compared to omphalocele patients without cardiac defects, children with this association are more likely to experience prolonged hospitalizations, neurologic, and cognitive impairments. Major cardiac abnormalities such as structural defects that require surgical treatment or result in developmental delay will significantly increase the death rate of patients with omphalocele. In conclusion, the prenatal diagnosis of omphalocele and early detection of other associated structural or chromosomal anomalies are of overwhelming importance, contributing to the establishment of antenatal and postnatal prognosis.
Understanding the breakdown of classic two-phase theory and spray atomization at engine-relevant conditions

A generalized framework for multi-component liquid injections is presented to understand and predict the breakdown of classic two-phase theory and spray atomization at engine-relevant conditions. The analysis focuses on the thermodynamic structure and the immiscibility state of representative gas-liquid interfaces. The most modern form of Helmholtz energy mixture state equation is utilized which exhibits a unique and physically consistent behavior over the entire two-phase regime of fluid densities. It is combined with generalized models for non-linear gradient theory and for liquid injections to quantify multi-component two-phase interface structures in global thermal equilibrium. Then, the Helmholtz free energy is minimized which determines the interfacial species distribution as a consequence. This minimal free energy state is demonstrated to validate the underlying assumptions of classic two-phase theory and spray atomization. However, under certain engine-relevant conditions for which corroborating e.
The development and applications of nanoporous gallium nitride in optoelectronics: a review

The development of nanoporous gallium nitride (NP-GaN) has widened the material properties and applications in third-generation semiconductor areas. NP-GaN has been used in laser emitters, light-emitting diodes, optical sensors, and optical energy storage devices. In this paper, we reviewed the most recent progress in the NP-GaN field by electrochemical etching. The etched GaN has many superior properties compared with original GaN templates, such as stronger photoluminescence intensity, thermal conductivity, piezo-electricity, more accessible area, stress relief, and refractive index. These advantages will make GaN more widely used in the field of optics and optoelectronics. Pore formation can be controlled by adjusting the applied potential and etching time. The NP-GaN makes the material of GaN have broader application prospects. We introduced in detail the application prospects of different GaN based processes and subsequent application methods in optoelectronics, sensors, and materials themselves. This review will help to improve further development of NP-GaN applications.

REM Sleep Impairment May Underlie Sleep-Driven Modulations of Tinnitus in Sleep Intermittent Tinnitus Subjects: A Controlled Study

(1) Background: Poor sleep and fragmented sleep are associated with several chronic conditions. Tinnitus is an auditory symptom that often negatively combines with poor sleep and has been associated with sleep impairment and sleep apnea. The relationship between tinnitus psychoacoustic characteristics and sleep is still poorly explored, notably for a particular subgroup of patients, for whom the perceived loudness of their tinnitus is highly modulated by sleep. (2) Methods: For this observational prospective study, 30 subjects with tinnitus were recruited, including 15 “sleep intermittent tinnitus” subjects, who had reported significant modulations of tinnitus loudness related to night sleep and naps, and a control group of 15 subjects displaying constant non-sleep-modulated tinnitus. The control group had matching age, gender, self-reported hearing loss grade and tinnitus impact on quality of life with the study group. All patients underwent a polysomnography (PSG) assessment for one complete night and then were asked to fill in a case report form, as well as a report of tinnitus loudness before and after the PSG. (3) Results: “Sleep Intermittent tinnitus” subjects had less Stage 3 sleep (p < 0.01), less Rapid-Eye Movement (REM) Sleep (p < 0.05) and more Stage 2 sleep (p < 0.05) in proportion and duration than subjects from the control group. In addition, in the “sleep Intermittent tinnitus” sample, a correlation was found between REM sleep duration and tinnitus overnight modulation (p < 0.05), as well as tinnitus impact on quality of life (p < 0.05). These correlations were not present in the control group. (4) Conclusions: This study suggests that among the tinnitus population, patients displaying sleep-modulated tinnitus have deteriorated sleep quality. Furthermore, REM sleep characteristics may play a role in overnight tinnitus modulation. Potential pathophysiological explanations accounting for this observation are hypothesized and discussed.
Generation Z Students Characteristics and Attitude in a Chinese English Language Teaching Classroom

Recently, the notion of Generation Z has been received a wide attention in various academic studies. As the generation who were born and raised in the era of the Internet, digital tools, and social media, Generation Z tend to have different characteristics from the previous generations. In this respect, this paper focuses on providing a better view of Generation Z characteristics and their attitude towards English writing and classroom instructions in an English as foreign language classroom in Yunnan, China. Questionnaires and essay analysis were used to present the experimental Generation Z students opinions and their writing features. The results indicated the experimental Generation Z students have shown both the general characteristics (such as tech savy, multi-taskers) and the typical Chinese characteristics, and that these students had negative attitude to English writing and classroom instructions. As the current English language teaching seems ineffective in meeting the needs of Generation Z students in an L2 English language classroom, this paper concludes that it is urgent for language teachers to find effective methodology to enable the Generation Z students to achieve more in their English language learning practices.
