    Abstract Recently, groundwater resources in Egypt have become one of the important sources to meet human needs and activities, especially in coastal areas such as the western area of Port Said, where seawater desalination cannot be used due to the problem of oil spill and the reliance upon groundwater resources. Thus, the purpose of the study is the sustainable management of the groundwater resources in the coastal aquifer entailing groundwater abstraction. In this regard, the Visual MODFLOW and SEAWAT codes were used to simulate groundwater flow and seawater intrusion in the study area for 50 years (from 2018 to 2068) to predict the drawdown, as well as the salinity distribution due to the pumping of the wells on the groundwater coastal aquifer based on field investigation data and numerical modelling. Different well scenarios were used, such as the change in well abstraction rate, the different numbers of abstraction wells, the spacing between the abstraction wells and the change in screen depth in abstraction. The recommended scenarios were selected after comparing the predicted drawdown and salinity results for each scenario to minimize the seawater intrusion and preserve these resources from degradation.

    Abstract Objectives: to compare between immediate cord clamping, delayed cord clamping, and umbilical cord milking and their effects on hemoglobin and bilirubin level in term infants in cesarean section.
    Study design: A randomized clinical trial was conducted from November 2021 to June 2022, including 162 full term pregnant women undergoing elective cesarean section at EL-Shatby Maternity University Hospital. They were randomly assigned (1:1:1 ratio) either to immediate cord clamping just after delivery (Group 1) or delayed cord clamping for 30 s (Group 2) or umbilical cord milking 10 times for 10-15 s (Group 3). The primary outcome measures included hemoglobin and hematocrit levels of the newborn at birth and the secondary outcome was bilirubin level measurement at 72 h of life.
    Results: one hundred sixty- two newborns were randomized into 3 groups, fifty-four cases in each, and were investigated on hemoglobin and hematocrit levels; five were lost to follow-up and one hundred fifty-seven were tested for bilirubin. Participants among groups had no significant difference regarding demographic and clinical characteristics, regarding the hemoglobin at birth it was significant higher in the umbilical cord milking group (Group 3) through all groups (14.91 ± 0.91 g/dl vs15.38 ± 0.74 g/dl vs 16.56 ± 1.03 g/dl, p value <0.001), regarding hematocrit level at birth it was significant in the umbilical cord milking group (Group 3) through all groups (44.71 ± 2.94 vs 46.48 ± 2.61 vs 49.74 ± 3.26, p value <0.001). On the other hand, bilirubin level after 72 h had no significant different through the 3 groups (8.80(IQR 4.50-17.20), vs 9.70(IQR3.50-14.70), vs 8.50(IQR 3.20-19.50), respectively p value= 0.348).
    Conclusion: this study showed that umbilical cord milking 10 times for 10-15 s is more effective than delayed cord clamping for 30 s in enhancing hemoglobin and hematocrit levels in newborn delivered by cesarean section with no significant difference on bilirubin level in the newborn.

    Abstract Purpose: To assess the visual, ocular, extraocular, and multifocal electroretinography (mfERG) outcomes of computer vision syndrome (CVS) among medical students.
    Methods: This study was designed as a cross-sectional case-control study that included 733 medical students. All students completed a specially designed and validated CVS questionnaire survey (CVS-F3). Students from the control (No-CVS) and CVS groups underwent comprehensive ophthalmic examinations including the mfERG examinations. Our main outcome measures included uncorrected and corrected distance visual acuity (UDVA and CDVA, resp.) measurements, subjective and cycloplegic refractions, slit-lamp examination, intraocular pressure measurement, pupillary reflexes tests, ocular movements' tests, dry eye disease tests, and fundus and mfERG examinations.
    Results: The CVS-F3 identified that 87.9% of students had complaints that might be related to CVS. We documented a 76% prevalence rate in students undergoing an ophthalmologic exam. The most common ocular and extraocular complaints included visual blur and headache (40.9% and 46.8%, resp.). Statistical logistic and linear regression analyses showed that refractive errors, prolonged screen-hours, close eye-screen distance, improper gaze angle, poor screen-resolution, and screen-glare were risk factors for developing CVS and influencing its severity. In the mfERG subgroup, 42.5% demonstrated reduced amplitudes of mfERG rings and quadrants, indicating reduced foveal responses.
    Conclusion: Surveys cannot yield an accurate CVS prevalence. However, they help to identify subjects at risk who should be comprehensively assessed to confirm or exclude CVS diagnosis. Smartphone misuse primarily caused CVS among users. Our mfERG findings might be a sign of potential CVS visual sequelae; however, future studies are warranted. Clinicians need to understand these sequelae to appropriately identify and treat CVS.

    Abstract Background: Living under siege and deteriorated health, social, educational, and economic conditions and isolation with scarce opportunities to fulfil basic needs and aspirations affect the civil population's mental health and perceived quality of life. In this cross-sectional investigation, we explored the consequences of mental distress, fear of COVID-19, and social support for QoL in the Gaza strip.
    Methods: Nine hundred seventy nine (32.9% males; 67.1% females; mean age was 35.2 years; s.d. = 11.4) adults were recruited in the Gaza strip. We used the Fear for COVID-19 scale (FCS-19), The WHOQOL-BREF Scale, Berlin Social Support Scale (BSSS), Depression Anxiety and Stress Scale (DASS). Pearson correlation coefficient was computed to assess relationships between quality of life, fear of COVID19, mental distress, and social support; a hierarchical regression analysis was used to assess the association between QoL as the dependent variable and demographic variables and fear of COVID19, mental health, and social support as the independent variables.
    Results: QoL was positively associated with perceived emotion, instrumental, and support seeking. Depression, anxiety, stress, and fear of COVID19 were negatively associated with quality of life. Gender was significantly associated with lower QoL. The study highlighted that the level of fear of COVID-19 was negatively influencing individuals' quality of life (QoL). This fear was negatively associated to psychological distress, gender, place of residence, and family type. Lower-educated and poorer participants had lower QoL scores. Conversely, female gender was notably linked to a lower QOL. The hierarchical regression confirmed that COVID-19 was an added burden for the Palestinian population. The fear of COVID-19 term added a 6.2% variance in QoL. In the final analysis, all predictors were statistically significant, with the fear of COVID-19 term recording a higher contribution of 22.5%, followed by depression term with 21.5%, perceived emotional 18.5%, income at 15.4%, and perceived instruments at 14.8% towards QoL.
    Conclusions: Practitioners and policymakers must consider the severe violation of human rights when developing psychosocial programs to intervene in the COVID-19 crisis.

    Abstract The main objective of this work was to fabricate smart nanocomposite transparent conductive biophysiological electrodes based on modified graphene oxide (GO). The GO is abundant, flexible conductors that can be formulated as a transparent sheet and thereby alleviate the drawbacks of using indium tin oxide in transparent electrodes, like its scarcity, brittleness, and cost. GO was synthesized by a modified version of Hummers' method under highly acidic conditions with sulfuric acid and showed good distribution at a high temperature of 90 °C. Polyvinyl alcohol (PVA) was used as a polymer host in the composite. Glycerol (Gl) was used to increase the flexibility and conductivity through an esterification reaction. Characteristic techniques were used to detect the morphology and structure of GO fillers and their polymer composites, such as transmission electron microscopy, x-ray diffraction, scanning electron microscopy and Fourier transform infrared spectroscopy. The GO/Gl/PVA transparent nanocomposite was tested for the synthesis of electrocardiogram (ECG) and electrodermal (EDA) electrodes. The Biopac device was used to evaluate the behavior of the GO/Gl/PVA plastic transparent electrode in comparison to the GO/Gl/PVA black electrode and a commercial one. The results indicated improved efficiency of the GO/Gl/PVA ECG transparent electrode. The GO/Gl/PVA EDA electrode produced signals with higher conductivity and lower noise than the commercial electrode.

    Abstract Secure data transmission is critical in public video surveillance applications such as tracking missing persons in large crowd gatherings. It may help the security personnel to monitor & record the live feeds from multiple cameras. However, this live streaming could be falsified. Various cryptographic techniques have been proposed to ensure the integrity of transmitted images, but continuous attacks still pose serious challenges to ensuring the integrity and authenticity of transmitted images. This work proposes a new chaotic-based watermarking technique to ensure the integrity of the transmitted video frames, and since the frames come from multiple cameras, the scheme should be as simple as possible and as fast as possible, the simplicity manifests in designing a fragile watermarking scheme therefore, the watermark is to be embedded in the spatial domain by direct manipulation of the values of the cover’s pixels. To ensure the security of the proposed scheme, chaotic maps have been deployed to reach an acceptable level of security with minimum computational overhead. The proposed scheme is novel in design in terms of the chaotic maps used and it is tested in challenging large gathering scenario. Experimental results demonstrate that the proposed method successfully locates any falsification in the transmitted images, and the performance of the scheme evaluates different types of attacks. Our testing results in good rate tamper of detection with TPR=99.2005, TNR=99.0777 and with a good quality of imperceptibility for the watermarked image with PSNR=43.82dB, SSIM=00.9955.
