Experiences of Instructors in Online Teaching: A Phenomenological Study

The abrupt shift to online distance education as a result of COVID-19 pademic resulted to the diversification of teaching modalities and pedagogies. This study explored the lived experiences of instructors in online teaching during the SY 2020-2021 using Van Manen's hermeneutic phenomenological design. Purposive sampling was used to select the twenty-five participants for the study. In-depth face-to-face interviews were conducted with all the participants to gather information from the teachers. Data analysis was employed using the six components of hermeneutic phenomenological design and with the aid of NVivo software. Results revealed that the instructors’ experiences in online teaching were identified in five themes: preparation of learning materials, realization of learning outcomes, stability of internet connection, availability of technological resources, and difficulty in the conduct of assessment activities. The instructors encountered positive and negative experiences in online teaching. Online teaching enhancement program is recommended in this study.
A Phase 2 Exploratory Trial of a Vocabulary Intervention in High Poverty Elementary Education Settings

This article reports results of a phase 2 exploratory trial of a vocabulary program delivered in elementary schools to improve student’s reading ability, including their comprehension. The intervention was tested as a targeted intervention in classrooms with children aged 7–10 across 20 weeks during one school year, with eligible students learning in small groups of four. Teachers and support staff received training in this cooperative learning approach to develop children’s vocabulary with particular focus on Tier‐2 words. School staff received additional support and resources to equip them to develop and implement the vocabulary instruction sessions to targeted students. The trial was undertaken with a sample of 101 students in seven schools from three English district areas with high levels of socio‐economic disadvantage. A standardized reading test was used to measure reading outcomes, with significant gains found in student’s overall reading ability, including comprehension. Owing to the positive results found in this trial, including positive feedback about implementation of the technique, next steps should be a larger trial with 48 schools to avoid the risk of sampling error due to limited number of schools.
Assessment of Reference and Actual Evapotranspiration, and Yield of Maize Using Different Levels of Irrigation and Filter Mud Cake

Two experiments were conducted at Water Studies and Research Complex (WSRC), Station, National Water Research Center, Toshka – Abu Simbel, during two growing seasons of 2018 and 2019 to compare available reference evapotranspiration (ET◦) equations (HargreavesSamani (HS), Makkink (MK), Priestley–Taylor (PT) and Turc (TC)) to the FAO-56 method to determine suitable alternatives for use in Toshka region, and to evaluation effects of drought stress and filter mud cake on physiological traits of two maize hybrids, three regulated deficit irrigation levels of available water content depletion (AWCD) I1, 13 %, I2, 25% and I3, 50% AWCD were combined with three levels of filter mud cake (FMC) F1: 4 kg m , F2 : 2 kg m and F3 : 0 kg. The data revealed that the individual influence of used 13% AWCD and FMC 4 kg m, caused increases of the plant height (m), leaf area (cm), no. grains/cob, grain yield (ton/fed.) and water use efficiency (WUE) (Kg/m). The data also, revealed that the average seasonal values of the actual evapotranspiration (Eta) decreased as the percentage of soil moisture depletion increased (more available water extracted) . The Eta values were 1012.5, 853.1 and 712.7mm at 13, 25 and 50% AWCD, respectively. The data also, revealed that the grain yield in the first season (2017/2018) were 1.70, 1.32 and 0.77 ton/fed. While in the second season (2018/2019) were 1.85, 1.53 and 0.75 ton/fed for 13, 25 and 50% AWCD, respectively. The data revealed that increased regime treatment from 13 to 50% AWCD decreased WUE by maize plants from (0.45 to 0.29 kg/m) and (0.48 to 0.27 kg/m)in 2017/2018 and 2018/2019, respectively. The results showed that the Hargreaves Samani (HS) equation is suitable for estimating ETo for the studied area.
Comparison of techniques for counting prokaryotes in marine planktonic and biofilm samples

Though a large number of techniques are available for the study of aquatic bacteria, the aim of this study was to establish a technique for analysing free-living and biofilm prokaryotic cells through laboratory assays. In particular, we wished to analyse the efficiency of ultrasound to detach and disrupt biofilm, to obtain an efficient stain treatment for quantifying free-living and biofilm prokaryotes in flow cytometry (FC), and to compare epifluorescence microscopy (EFM), scanning electron microscopy (SEM) and FC for quantifying free-living and biofilm prokaryotes#. Marine-grade plywood substrates were immersed in natural marine water that was conditioned for 12 days. At 6 and 12 days, water aliquots and substrates were removed to estimate free-living and biofilm prokaryote density. Ultrasound efficiently removed marine biofilm from substrates (up to 94%) without cell damage. FC analysis (unstained) reliably quantified marine plankton and young or mature biofilm prokaryotes compared with other staining (acridine orange, 4′,6-diamidino-2-phenylindole, propidium iodide and green fluorescent nucleic acid), EFM or SEM techniques. FC and SEM achieved similar results, while a high variability was observed in the EFM technique. FC was faster and more precise than SEM because the count is not dependent on the observer.
Impact of Cypermethrin 25% EC and pH on Certain Haematological Parameters of Cyprinid Fish Puntius javanicus

In present study an attempt has been made to investigate the combined impact of sub lethal toxicity of Cypermethrin 25% EC and pH on certain blood parameters of Puntius javanicus. Adult fish were exposed to sublethal concentration (0.36 µg/L) of cypermethrin 25% EC in different pH water i.e. pH 5, pH 6, pH 7, pH 8.5 and pH 9.5 for 15 days. Significant changes in red blood cell (RBCs) count, total white blood cells (WBCs), haemoglobin % (Hb%), haematocrit value, total serum protein and blood glucose level were observed in fish exposed to sub-lethal concentration of cypermethrin. Significant decrease in red blood cell (RBCs) count, haemoglobin % (Hb %), haematocrit value and total serum protein content were found in fish exposed to sub-lethal concentration of cypermethrin in pH 5, pH 6 and pH 9.5, compared to fish exposed to sub-lethal concentration of cypermethrin in pH 7. A significant increase in these parameters were documented in fish exposed to sub-lethal concentration of cypermethrin in pH 8.5, compared to fish exposed to sub-lethal concentration of cypermethrin in pH 7. On the other hand a significant increase of total white blood cells (WBCs) and blood glucose level were recorded in fish subjected to sub-lethal concentration of cypermethrin in pH 5, pH 6 and pH 9.5, compared to fish exposed to sub-lethal concentration of cypermethrin in pH 7. Values of these parameters were decreased significantly in fish exposed to sub-lethal concentration of cypermethrin in pH 8.5, compared to fish exposed to sub-lethal concentration of cypermethrin in pH 7. The values of all studied blood parameters in fish subjected to sub-lethal concentration of cypermethrin in pH 8.5 were almost found to retain the values of control group (pH 7, without toxicant).

Mobile Phones: Vital Addiction or Lethal Addiction? Mobile Phone Usage Patterns and Assessment of Mobile Addiction among Undergraduate Medical Students in Telangana, India

Background Increased mobile phone usage among undergraduate medical students causes a detrimental effect on their health. The main focus of this study is to determine the pattern of mobile phone usage among undergraduate medical students in Hyderabad, India, and the detrimental effect on their health due to excess mobile use. Materials and Methods A cross-sectional study was conducted among undergraduate medical students from various medical colleges in Hyderabad, India, from September 2020 to January 2021. Data were collected from 626 respondents using a semistructured, pretested questionnaire. Smartphone Addiction Scale-Short Version (SAS-SV) was used to assess the risk of smartphone addiction. Microsoft Excel and SAS were employed to analyze the data. Associations were examined using Fisher's exact test. Results 100% of the respondents were using mobiles, with 83.2% spending more than 4 hours on them. Only 22% reported that no mobile use during classes. Half (51.6%) admitted to keeping their mobiles close by while sleeping. 84.3% used social networking apps via their mobiles. Common symptoms arising from prolonged mobile usage included eye strain (67.9%), blurred vision (31.4%), and numbness or tingling in palms (30.9%). 52.70% of the respondents were at high risk of mobile addiction according to SAS-SV. Screen time more than 4 hours was associated with high risk of mobile addiction (p < 0.0001). Significant association was found between high risk of mobile addiction and eye strain (p < 0.0001), blurry vision (p=0.0115), numbness/tingling in palms (p < 0.0001), and heat/tingling in the auditory area (p < 0.0001). Conclusion The study shows the alarming rate of risk of smartphone addiction among medical students. Students can be encouraged to assess their mobile addiction status and become aware of the issue. More research may be performed to develop standardized tools for early identification of mobile addiction and appropriate therapies for its rectification.
Analysis of Big Data Storage Tools for Data Lakes based on Apache Hadoop Platform

When developing large data processing systems, the question of data storage arises. One of the modern tools for solving this problem is the so-called data lakes. Many implementations of data lakes use Apache Hadoop as a basic platform. Hadoop does not have a default data storage format, which leads to the task of choosing a data format when designing a data processing system. To solve this problem, it is necessary to proceed from the results of the assessment according to several criteria. In turn, experimental evaluation does not always give a complete understanding of the possibilities for working with a particular data storage format. In this case, it is necessary to study the features of the format, its internal structure, recommendations for use, etc. The article describes the features of both widely used data storage formats and the currently gaining popularity. Keywords—Big data formats; data lakes; Apache Hadoop; data warehouses
Retinal Neuropathy in IGT Stage of OLETF Rats: Another Characteristic Change of Diabetic Retinopathy

Aims We investigated the changes of retinal structure in normal glucose tolerance (NGT), impaired glucose tolerance (IGT), diabetes mellitus (DM), and diabetic kidney disease (DKD) stages in Otsuka Long-Evans Tokushima Fatty (OLETF) rats. Methods We assigned OLETF rats to four groups based on their OGTT results and 24 h urinary microalbumin (24 h UMA) levels: NGT, IGT, DM, and DKD groups. We observed the structural and the corresponding pathological changes and quantified the expression of HIF-1α, iNOS, NF-κB, VEGF, ICAM-1, and occludin in the retina. Results Significant damage to the retinal structure, especially in retinal ganglion cells (RGCs), was observed in the IGT stage. The expression of HIF-1α, iNOS, NF-κB, VEGF, and ICAM-1 was significantly upregulated, while that of occludin was downregulated. Conclusion Significant retinal neuropathy occurs in the IGT stage. Inflammation and hypoxia may damage the blood retina barrier (BRB), leading to diabetic retinopathy.
Association Between Nutritional Status and Manual Grip Strength in Oncologic Patients in Palliative Care

Introduction: Nutritional monitoring in palliative care is extremely important, since levels of mortality, malnutrition and unintentional weight loss occur in the majority of cancer patients. In this way, it is possible to prevent nutritional deficiencies and weight loss, which leads to a worsening nutritional status. Objective: The aim of the study was to evaluate the association between the classification of nutritional status obtained by the patient-generated subjective global assessment (PG-SGA), handgrip strength (HGS) and adductor pollicis muscle (APM) in cancer patients palliative. Method: We evaluated 70 cancer patients enrolled in the exclusive palliative care program. The PG-SGA was used to assess the nutritional status. To evaluate the association of nutritional status with other predictive measures, HGS measurements were performed with a dynamometer and APM with an adipometer. Descriptive statistics and linear regression analysis were used to evaluate the ability of these measures to predict nutritional status. Results: Of the 70 patients, aged between 31 and 101 years, in which 58.6% were male and malnutrition (B+C) was found in 87.2% (n=61) according to PG-SGA. The value of APM was altered in 72.9% (n=51) patients and 42.9% (n=30) in HGS. HGS was associated with PG-SGA (b=-0.273, p=0.04) and APM didn’t (b=-0,124; p=0.546); therefore, only HGS was a good predictor of nutritional status in this study. Conclusion: It’s suggested the use of HGS to evaluate nutritional status in palliative cancer patients.
Iranian Native Medicinal Plants Affecting Staphylococcus aureus as Septic Pathogens: An updated Review

Infectious diseases kill thousands each day around the world [1]. Staphylococcus aureus is the second leading pathogenic cause of nosocomial infections [2]. S. aureus is a pathogenic bacterium that produces catalase. This bacterium plays an important role in the development of food poisoning and purulent, respiratory, and nosocomial infections [3]. This bacterium is a major contributor to infections such as toxic shock syndrome, toxic sepsis, abscess, food poisoning, third grade burns, traumatic ulceration, surgical incision, bed sores or atrophic ulcers [4, 5]. Reports have indicated that 25-30% of people in different communities are nasal carriers of the bacterium [6]. The increasing incidence of bacterial resistance to antibiotics as well as the side effects of these drugs have been among the factors that have led to the spread of research on medicinal plants in recent years [7]. Long-term use S aureus is the second leading pathogenic cause of nosocomial infections and plays an important role in the development of food poisoning and purulent, systemic and nosocomial infections. This bacterium is responsible for infections such as abscess, food poisoning, third grade burns, traumatic ulcers, surgical incisions, bed sores or atrophic ulcers. Long-term use of antibiotics has led to the emergence of multi-drug resistant strains in infectious diseases. Due to increased resistance of bacteria to chemical drugs and the few side effects of medicinal plants, medicinal plants have nowadays attracted much more attention of researchers. In this regard, studies have been done on the effectiveness of medicinal plants against infectious agents such as S. aureus and methicillin-resistant S. aureus. Therefore, in this review study, native Iranian herbs that are effective on S. aureus were reported. In this review study, search terms including Staphylococcus aureus, herbs, extracts and essential oils were used to retrieve articles indexed in databases such as the Institute for Scientific Information, PubMed, Scopus, Scientific Information Database, Magiran, and Google Scholar. Garlic, pomegranate, Anethum graveolens, coriander, eucalyptus, Lawsonia inermis, Descurainia sophia, Figworts, artemisia, thyme, etc. are some of the most important anti-staphylococcal herbs.
The effect of Hofstede’s cultural dimensions on the degree of compliance with IFRS Standards in developing countries

This paper aims to highlight the cultural impact of Hofstede (1980) on the degree of compliance with International Financial Reporting Standards (IFRS) in 55 developing countries for the year 2014, based on the method adopted by Elad (2015) in order to identify IFRS Standards. Results show that culture (by means of three components, namely power distance, uncertainty avoidance, and masculinity) does not promote the degree of compliance with IFRS. However, only one significant relationship was found between individualism and the degree of compliance with IFRS Standards. This finding confirms Gray’s (1988) observation that individualism fosters a climate of transparency and professionalism
Effect of “Time To Surgery” On The Endometrial Cancer Prognosis

OBJECTIVE: Endometrial cancer is the most common gynecological cancer in developed countries. Our study aims to determine the effect of the time between diagnosis and surgery of endometrial cancer on the prognosis of the disease. STUDY DESIGN: Patients who were diagnosed with epithelial type endometrial cancer and did not receive preoperative chemotherapy, radiotherapy, or hormonal therapy were included in the study. RESULTS: Two hundred eighty-five patients were included in the study. We divided the patients into two groups regarding before and after 8 weeks from diagnosis to surgery. Clinical characteristics of the patients were comparable between the groups, except for comorbid conditions and body mass index. Using cox-regression analysis, time to operation did not have a significant effect on both recurrence and cancer-associated death risk. The log-rank test analysis also showed that there was no significant difference in progression-free survival and disease-specific survival between the patients. There was no significant difference between the groups in terms of progression-free survival and disease-specific survival for cases with endometrioid type grade 1-2 tumors. There was also no significant difference between the groups regarding progression-free survival and disease-specific survival in the patients with tumors of endometrioid type grade 3 and non-endometrioid histology. CONCLUSION: Time delay between diagnosis to surgery of the patients with endometrial cancer has no prognostic importance for recurrence and survival outcomes.
Effect of pH, Sucrose Concentrations and Medium States on in vitro Root-ing of Pineapple (Ananas comosus (L) Merr) cv Queen

The effect of medium states (liquid, semi solid, solid), pH (5.0, 5.5, 6.0, 6.5) and sucrose concentrations (10, 20, 30, 40 g/l) on in vitro rooting of pineapple cultured in full strength MS enriched with IBA at 0.5 mg/l were investigated. According to average overall sucrose concentrations, overall pH adjustments, and at each combination of equal sucrose and pH, liquid medium was always super than solid and semisolid. The tallest plantlets (66 to 71 mm) obtained in liquid medium enriched with sucrose at 10 and 20 g/l both adjusted to pH 6.0; sucrose at 20 g/l and adjusted to pH 6.5 and sucrose at 30 g/l and adjusted to pH 5.0. All of the above combinations except sucrose at 20 and pH 6.0 resulted in 100% rooting. Sucrose at 30 g/l and pH 5.0 resulted in two times more (11 roots per shoot) and three times longer roots (39 mm) than the other treatments (5 roots each about 14 mm long). Each rooting parameter had different optimum combinations of medium state, sucrose and pH adjustment. For any parameter, proper pH adjustment could reduce the optimal sucrose enrichment from 30 to 20 and even to 10 g/l. Hence, pH adjustment is suggested as an important approach for reduction of in vitro rooting medium cost.
Diagnostic Value of Serum Autotaxin Levels in Liver Fibrosis in Children with Chronic Hepatitis

Liver biopsy is the most accurate examination method to evaluate liver fibrosis stage but is invasive. Non-invasive biomarkers of disease progression are therefore needed. The study aimed toassess the role of serum autotoxin levels in diagnosis of liver fibrosis in children with chronic hepatitis.This study was a case controlled study that was conducted on a total number of 80 children of both sex. 50 children (case group) collected from outpatient pediatric hepatology clinic of Benha University hospitals and National Liver Institute Monoufia University. 30 apparently healthy children (control group) matched the patient group in age and sex. All children subjected to full history taking, physical examination and Laboratory Investigations: CBC, AST, ALT, GGT, alkaline phosphatase, serum bilirubin, serum albumin, PT, PTT, INR, total protein, total serum IgG levels, hepatitis markers (HAV, HBV&HCV), liver biopsy and serum autotaxin level by ELISA. There was statistical significant difference (P value <0.01) among chronic hepatitis group and control group regarding HB, platelet, total protein as they were lower in chronic hepatitis group than control group, while PT, INR, AST, ALT, GGT, ALP and bilirubin (total& direct) were higher in chronic hepatitis group than control group.There was statistical significant differencebetween studied groups regarding serum autotaxin as it was elevated in chronic hepatitis group. There were statistical significant differences between serum level of autotaxin and fibrosis index, hepatitis activity index and interface hepatitis as it increases with increase fibrosis index, hepatitis activity index and interface hepatitis. The best cut off value of serum autotaxin was 10.45ng/ml for detection of early fibrosis stage with sensitivity 97.6%, specificity 93.8% and area under the curve is 0.961 while the best cut off serum autotaxin for detection of moderate fibrosis was 18.15ng/ml with sensitivity 85%, specificity 93.8% and area under the curve is 0.984. Autotaxin may be a novel non-invasive biomarker for liver fibrosis done on Egyptian children with chronic hepatitis.
ANTIMICROBIAL RESISTANCE OF ESCHERIСHIA COLI STRAINS ISOLATED FROM PATIENTS WITH PURULENT PERITONITIS

Escherichia coli remains one of the most frequent causes of several common bacterial infections in humans. Surgery on the abdominal cavity is usually complicated by peritonitis caused by E. coli strains. Recently, there are data confirming the high degree of resistance of this strain. The prevalence of multidrug-resistant E. coli strains is increasing worldwide principally due to the spread of mobile genetic elements, such as plasmids. The rise of multidrug-resistant strains of E. coli also occurs in Ukraine. Therefore, the spread of resistance E. coli is an increasing public health concern in our country. This paper summarizes the antibiotic resistance of clinical E. coli strains, isolated from patients with peritonitis. Furthermore, therapeutic interventions and strategies to prevent and control infections are presented and discussed. The article also provides an overview of the current knowledge concerning promising alternative therapies against E. coli diseases.
