Authors: Dinku Getahun Fetene 
Published: June 2022

Abstract
Today, the increasing population in urban areas is forcing government agencies, builders and investors to focus on building real estate housing. However, the affordability of these housing is becoming a concern. This research examines the affordability of real estate housing in Bahir Dar. The study utilizes household income survey; conducts real estate market assessment; explores town housing policy and land tenure system; values financial accessibility; investigates the housing demand; compares and contrasts the experience of international housing policy and land tenure system with local system. The study develops a conceptual housing policy framework to address the housing affordability challenge. Four common internationally accepted approaches were used to measure the affordability of real estate housing. Based on the study a median household has 4,500 Birr monthly income. Results show that only 20% of residents have their own housing unit, while the majorities are living on rent and/or other means. Price of a prevailing standard real estate housing unit is approximately 2,200,000 Birr. Presently, only 14% of real estates are owned by local residents from more than 600 real estate houses sold in the city. This study can help the Municipal Government in identifying possible groups who need housing subsidy and can take a lesson to improve the housing policy. In addition, real estate investors can use it in improving their market strategies. Individuals can also benefit from the research for decision-making when investing in real estates.

Published: June 2022

Abstract
Background
The use of electrolyzed water has brought recent attention due to its antimicrobial properties. Indeed, electrolyzed water has been proposed for the sterilization of dental materials and instruments without compromising their structural integrity. In addition, electrolyzed water has been proposed as a mouthwash to control bacterial and viral oral infections without detrimental effects on the oral mucosa. However, there is no current consensus or evidence synthesis that could indicate its potentially favorable use in the dental setting, particularly nowadays during the COVID-19 context. Therefore, this systematic review aimed to elucidate whether the use of electrolyzed water could improve the microbiologic control in the COVID-19 pandemic dental setting.
Methods
MEDLINE via Pubmed, EMBASE, Cochrane’s CENTRAL, Scopus, LILACS, and Web of Science databases were searched up to September 2021 to identify experimental studies utilizing electrolyzed water for eliminating microorganisms in a dental setting. Besides, a manual and a grey literature search were performed. The data selection and extraction were performed individually and in duplicate. The Risk of Bias (RoB) was assessed with the Nature Publication Quality Improvement Project (NPQIP) score sheet. The study protocol was registered at PROSPERO CRD42020206986.
Results
From a total of 299 articles, 63 studies met the inclusion criteria. The included studies assessed several types of electrolyzed waters, which showed a high disinfection potential when used to deal with different oral conditions. Electrolyzed water demonstrated a broad antimicrobial spectrum and was highly efficient in the dental office disinfection against viruses, fungi, and bacteria, being compatible with most dental materials. In addition, the use of electrolyzed water could be protective against SARS-CoV-2 infection and contamination in the dental office. Regarding the RoB, only 35.18% of entries were answered as ‘Yes’, thus achieving less than half of the reporting sheet.
Conclusion
Electrolyzed water is effective in disinfecting contaminated surfaces, dental materials, and equipment. Therefore, their use is recommendable in the SARS-CoV-2 pandemic dental setting.

Abstract
As one of the most important cloud computing services, cloud storage provides storage resources for resource-constrained users, which reduces their local overhead and computing cost. As an extension of cloud computing, fog computing introduces a fog layer between the cloud and users to deploy computing, storage, and other types of equipment, allowing users to operate outsourced data conveniently. Although cloud storage brings many conveniences to users, assured data deletion is still one of the crucial security challenges. In addition, since cloud servers usually store data in a decentralized manner, it is difficult for users to centrally and securely operate data blocks. This paper proposes an efficient and secure cloud data deletion scheme (SDUS-AD) that supports dynamic data updates in multi-copy scenarios. In this scheme, a new dynamic structure is designed, which improves the traditional Merkle hash tree, thereby realizing the dynamic update of outsourced data efficiently and safely. A cloud-fog-user layer structure is used to meet the needs of resource-constrained users (such as mobile users) to update data, and a secure and trusted fog cluster is constructed using the trusted cloud platform management model based on TPM alliance to ensure the confidentiality of data privacy. Security analysis shows that SDUS-AD meets real-world security requirements. Detailed performance analysis and simulation experiments show that SDUS-AD is efficient, safe, and feasible.

Published: June 2022

Abstract
In this paper, we present a generalized three-dimensional (3D) massive multiple-input multiple-output (MIMO) scattering model for high-speed train (HST) macro-cell wireless communication propagation environment. The proposed model introduces a track-side base station and mobile stations (MS) inside the train with local scattering clusters around (i.e., buildings, trees, signs et al.). Then, the time-varying channel parameters on account of moving properties of the MS and the power azimuth spectrum as well as the Doppler frequency shift of the scattering waves are investigated based on the geometric model. Furthermore, two underlying 3D massive MIMO antenna array models including the spherical array assumption and geometric angular properties are introduced for estimating the spatial fading correlation and channel capacities of the MIMO multi-antenna systems. Finally, numerical results show good agreement with previous models, which improves the utility of our proposed model for describing outdoor HST communication environments.

Abstract
With the rapid development of chemical industry, a large number of polycyclic aromatic hydrocarbons(PAHs) enter into the soil, which causes serious soil pollution. How to use sodium persulfate(Na2S2O8 ) to efficiently remedy the phenanthrene -contaminated soil, and to identify the influence on the soil in the process of remediation has became the core problem. In this paper, the effects of different environmental variables such as temperature, water-soil ratio, pH on the degradation of phenanthrene and the effects on soil during the degradation of phenanthrene were explored according to the reaction efficiency of sodium persulfate. In this experiment, when the temperature was 60°C, the water-soil ratio was 20:1, and the solution was slightly acidic, the Na2S2O8 utilization rate was the highest and also the overall degradation efficiency of the oxidation system was the highest. Na2S2O8 oxidation system can effectively degrade phenanthrene in soil, and thermally activated Na2S2O8 degradation of phenanthrene in soil conforms to quasi-first-order reaction kinetics. In the process of oxidation of phenanthrene with Na2S2O8 , soil structure was destroyed, caused acidification, and reduced the content of organic matter，which also had a negative impact on soil fertility and subsequent soil use function, the green and sustainable remediation should be considered.

Abstract
IntroductionTreatment with mirtazapine, a widely prescribed antidepressant, has been linked to weight gain and dyslipidemia. Whether dyslipidemia occurs secondary to increased appetite due to antidepressant treatment, or due to direct pharmacological effects of mirtazapine is unknown. Methods The aim of this analysis is to complement our previously published results of the effect of mirtazapine on metabolism and energy substrate partitioning from a proof-of-concept, open-label clinical study (ClinicalTrials.gov NCT00878540) in 12 healthy males (20-25 years). We report the effect of a seven-day administration of mirtazapine 30 mg per day on weight and lipid metabolism in healthy men under highly standardized conditions with respect to diet, physical activity and day-night-rhythm and under continuous clinical observation. ResultsAfter a seven-day administration of mirtazapine 30 mg, we observed a statistically significant increase in triglyceride levels (mean change +4.4mg/dl;95%CI[-11.4, 2.6];p=0.044) as well as TG/HDL-C ratio (mean change +0.2;95%CI[-0.4, -0.1];p=0.019) and a decrease in HDL-cholesterol (mean change -4.3mg/dl;95%CI[2.1, 6.5];p=0.004), LDL-cholesterol (mean change -8.7mg/dl;95% CI[3.8, 13.5];p=0.008), total cholesterol (mean change -12.3mg/dl;95%CI[5.4, 19.1];p=0.005), and non-HDL-C (mean change -8.0mg/dl;95%CI[1.9, 14.0];p=0.023). Notably, weight (mean change -0.6kg;95%CI[0.4, 0.8];p=0.002) and BMI (mean change -0.2;95%CI[0.1, 0.2];p=0.002) significantly decreased. No change in waist circumference (mean change -0.4cm;95%CI[-2.1;2.9];p=0.838) or waist-to-hip-ratio (mean change 0.0;95%CI[-0.0, 0.0];p=0.814) was observed.DiscussionThis is the first study showing unfavorable changes in lipid metabolism under mirtazapine in healthy individuals despite highly standardized conditions including dietary restriction, and despite the observation of a decrease of weight. Our findings support the hypothesis that mirtazapine has direct pharmacological effects on lipid metabolism. TRIAL REGISTRATION. ClinicalTrials.gov NCT00878540.
Damage behavior of sandstone induced by dry-wet cycle combined with acid environment

Published: June 2022

Abstract
Groundwater infiltration and ventilation drying have a significant influence on the stability of the surrounding rock mass during coal mine construction, especially when the groundwater quality is acidic. This paper presents an experimental study of the damage characteristics of sandstone that mimic the rock-fluid interactions affected by the combined action of acid environment and dry-wet cycle. Nuclear magnetic resonance(NMR) and uniaxial compression tests were conducted to characterize the physical and mechanical behavior, while X-ray diffraction(XRD) and scanning electron microscopy(SEM) were performed to analyze the compositional and microstructural changes respectively. The results reveal that as the number of cycles increases, the spectral area and porosity are always increasing, the peak strain increases, and the peak strength falls. And with higher acidity, the pore shifting trend is much more noticeable. With the rise of acidity, the minerals in the rock sample react violently with the acidic ion H+, resulting in a steady increase in the number of pores and fissures. The porosity is employed to define the rock damage. The functional relationship between the number of drying-wetting cycles and the damage degree was established by analysing the quantitative association of porosity with rock damage. Our study provides a better understanding of the damage mechanisms of sandstone, which could be used to predict the deformation and failure of rock.
A Sustainable Framework Design For A Geostationary Satellite Control Earth Station
Authors: Rahman Nur Shazana Abdul , Rahim Nadirah Abdul 
Published: June 2022

Abstract
Earth Station(s), Mission Operations Center (MOC), Science Operations Center (SOC), and the supporting infrastructure that connects them all constitute a ground network of communications satellite systems. As more Earth Stations are added to the ground network, additional aspects should be considered to ensure that the MOC can communicate with all the Earth Stations in the network. It also needs constant upgrades to ensure greater reliability and performance. The reliability of the geostationary satellite control Earth Station system can be improvised by designing the system with sufficient subsystem redundancies, numerous tests during the planning stage, and only the best components for its subsystems. Suitable maintenance actions performed on a regular basis also play a significant role in preventing cost overruns and undesirable failures. Therefore, this paper introduces a sustainable framework which encompasses reliability, affordability, and maintainability of an Earth Station system which is very crucial in system design.

Published: June 2022

Abstract
BackgroundMobility patterns are valuable in identifying transmission patterns for infectious diseases and in parametrizing mathematical models. Aggregated location data from mobile phones which have been the main means of measuring human mobility on a population level come with several limitations. MethodsWe explored the viability of using ground monitored air quality data as an alternative to aggregated location data from mobile phones in two cities in Uganda. We determined associations between air quality and human mobility and the effect of mobility restrictions on mobility and air quality using Pearson correlation (R), multivariable regression and visualized relationships using scatter plots. ResultsFine particulate matter (PM2.5) was negatively correlated with the government response stringency index for Kampala (R = -0.31, p<0.001) and Wakiso (R = -0.21, p<0.001). In Kampala, PM2.5 was positively associated with movement in grocery and pharmacy (R = 0.24, p<0.001), parks (R = 0.25, p<0.001), retail and recreation (R = 0.24, p<0.001), transit stations (R = 0.3, p<0.001) and work places (R = 0.2, p<0.001); and negatively correlated with movement in residential places (R = -0.3, p<0.001). Only associations between PM2.5 and movement in workplaces and residential places were statistically significant in Wakiso (R = 0.14, p<0.001 and R = -0.19, p = 0.003 respectively).ConclusionsThese findings suggest that air quality data are linked to human mobility data and could thus be used to monitor human movement patterns. This is a pioneer study to assess the value of air quality as a surrogate for human mobility.

Abstract
Purpose
The aim of this study was to evaluate the maternal, obstetric, and fetal risk factors, shoulder dystocia maneuvers, and perinatal outcomes of shoulder dystocia cases.
Methods
In this descriptive retrospective cross-sectional study, 66 documented shoulder dystocia (incidence 0.18%) groups from 36390 singleton vaginal deliveries between 2017 and 2022 in a gynecology&obstetrics hospital and 201 control groups selected from the computer-assisted randomization program on pregnancy, delivery, fetal and newborn outcomes data were evaluated and compared. Regression analysis were used to explain the relationship between the shoulder dystocia and risk factors.
Results
Mean age was significantly higher in the shoulder dystocia group (p < 0.05). In the stepwise binary logistic regression model analysis, hemoglobin level, abdominal circumference, femur length, estimated fetal weight, birth weight and second stage of labor were found to be significant risk factors for shoulder dystocia (p < 0.05). Measurement of abdominal circumference (sensitivity 81.8%, specificity 91.0%) and birth weight (sensitivity 62.4%, specificity 91.5%) were found to be the most significant risk factors for shoulder dystocia, while the other risk factors had low sensitivity (< 60.0%).
Conclusion
The low sensitivity of shoulder dystocia risk factors other than birth weight and abdominal circumference measurement indicates that the unpredictable feature of shoulder dystocia is preserved.

Abstract
Objectives
To determine associations between patient-provider communication (PPC) quality and ratings of health care received, self-efficacy, and management adherence among non-pregnant reproductive-age women with diabetes.
Methods
Longitudinal data from the 2012–2018 Medical Expenditure Panel Survey were analyzed. The sample included women of childbearing age (18–45 years) with diabetes (n = 493). Associations between PPC quality and overall health care rating, self-efficacy, and management adherence (eye exam, foot exam, flu vaccine, blood cholesterol, HbA1c) were evaluated before and after adjusting for age, race/ethnicity, marital status, education, poverty level, insurance, and perceived health status. Optimal PPC quality was measured by women’s report of whether or not their health care provider always listened, explained things, showed respect, spent enough time, gave specific instructions and demonstrated health literate practices (clear instructions and asking them to “teach-back” how they will follow instructions).
Results
Diabetes management adherence was significantly greater among women who reported receiving optimal PPC quality compared to those who did not (OR = 2.02; 95% CI = 1.09–3.76) after adjusting for covariates. There were no statistically significant differences in ratings of health care or diabetes care self-efficacy by PPC quality.
Conclusions for Practice:
Results demonstrate that non-pregnant women of childbearing age with diabetes who report optimal PPC quality have increased likelihood of diabetes care management adherence. This finding underlines the importance of providing training in communication-centered skills, which should be regularly implemented during healthcare encounters for women with diabetes, particularly for those at increased risk of poorer health outcomes due to and structural barriers to quality health care.

Abstract
A ternary photonic crystal of the structure (ABC)N (CBA)N is treated as a thermally tunable filter. Layers A, B and C are silver (Ag), silicon dioxide (SiO2) and Silicon (Si), respectively. The low-index layer (SiO2) is assumed to have a graded thickness according to four different functions. The thickness gradation functions are considered exponential, linear, quadratic and cubic. The transmission peaks at defect modes and their wavelength positions are investigated as functions of temperature and incident angle. The performance of each gradation function is investigated. Many findings are obtained. With the increase in temperature, the transmission peaks shift toward longer wavelengths. Transmissions at defect modes of TM polarization have higher values than those of TE polarization for the same incidence angle. The cubic function showed a transmission peak of 0.897 which is the highest among all functions.

Published: June 2022

Abstract
Background: The elderly population is rapidly increasing, particularly in India. The rise in the population of older adults has resulted in increasing social, economic, and health challenges. The main focus of this study was to determine the prevalence of quality of life and falls/injuries by socio-demographic characteristics, as well as the link/relationship between these factors and QOL. Materials & methods: The data for this study was used from the first wave of the Longitudinal Ageing Study in India. This study was done on 72000 older adults aged 45 and up. The characteristics and distribution of the study population were determined using descriptive analysis. Ordered logistic regression analysis was used to determine the association between health-related quality of life (HRQoL) and falls/ injuries among the elderly aged 60 and above.Result: According to HRQOL factors such as ADL (self-care), mobility, IADL (usual activities), pain, and depression, 8.5% of the elderly do not have self-care. 65.3% cannot move, 22.3% cannot engage in their usual activities, and approximately 40% are pain-free. The elderly suffer from pain, and 30% of the elderly suffer from depression. The elderly with injuries were 35% less likely to have a medium or high quality of life than the elderly without injuries. Conclusion: The quality of life among the elderly after major falls/ injuries has significantly declined. As per these findings, it is necessary to investigate the elements that are negatively related to the quality of life to allow the elderly to live a healthy and enjoyable life.
Finite element simulation of stresses in cutting tools during tapping

Published: June 2022

Abstract
Tapping is inherently more complex than other machining processes. The main reason for this complexity is that the chip removal process takes place in a closed environment. For this reason, in order to use the tap tools more efficiently, it is necessary to know the cutting conditions and the stresses that occur in the tool during cutting. In this study, holes of different diameters were drilled in the AISI 1050 material and threaded with M10 taps with three different geometries. Uncoated HSS and TiN coated HSS taps were used in the study. The tapping operations were carried out in dry conditions. The simulation conditions were chosen exactly the same as the experimental conditions. Stresses during tapping were analysed using the Third Wave AdvantEdge program based on the finite element method (FEM). The tapping tools were modelled by reverse engineering method and then imported in the program. In general, the coating applied to the tools positively affected the stresses on the cutting tool. Also, the stresses in tapping tools with helical were lower than in straight tools.
