Authors: Li Jing , Yin Jialin , Deng Lin 
Published: May 2021

AbstractIn the development of modern agriculture, the intelligent use of mechanical equipment is one of the main signs for agricultural modernization. Navigation technology is the key technology for agricultural machinery to control autonomously in the operating environment, and it is a hotspot in the field of intelligent research on agricultural machinery. Facing the accuracy requirements of autonomous navigation for intelligent agricultural robots, this paper proposes a visual navigation algorithm for agricultural robots based on deep learning image understanding. The method first uses a cascaded deep convolutional network and hybrid dilated convolution fusion method to process images collected by a vision system. Then, it extracts the route of processed images based on the improved Hough transform algorithm. At the same time, the posture of agricultural robots is adjusted to realize autonomous navigation. Finally, our proposed method is verified by using non-interference experimental scenes and noisy experimental scenes. Experimental results show that the method can perform autonomous navigation in complex and noisy environments and has good practicability and applicability.
Location-sharing protocol for privacy protection in mobile online social networks
Authors: Ruan Ou , Zhang Lixiao , Zhang Yuanyuan 
Published: May 2021

AbstractLocation-based services are becoming more and more popular in mobile online social networks (mOSNs) for smart cities, but users’ privacy also has aroused widespread concern, such as locations, friend sets and other private information. At present, many protocols have been proposed, but these protocols are inefficient and ignore some security risks. In the paper, we present a new location-sharing protocol, which solves two issues by using symmetric/asymmetric encryption properly. We adopt the following methods to reduce the communication and computation costs: only setting up one location server; connecting social network server and location server directly instead of through cellular towers; avoiding broadcast encryption. We introduce dummy identities to protect users’ identity privacy, and prevent location server from inferring users’ activity tracks by updating dummy identities in time. The details of security and performance analysis with related protocols show that our protocol enjoys two advantages: (1) it’s more efficient than related protocols, which greatly reduces the computation and communication costs; (2) it satisfies all security goals; however, most previous protocols only meet some security goals.

Published: May 2021

AbstractIn this paper, we propose a hybrid super-resolution method by combining global and local dictionary training in the sparse domain. In order to present and differentiate the feature mapping in different scales, a global dictionary set is trained in multiple structure scales, and a non-linear function is used to choose the appropriate dictionary to initially reconstruct the HR image. In addition, we introduce the Gaussian blur to the LR images to eliminate a widely used but inappropriate assumption that the low resolution (LR) images are generated by bicubic interpolation from high-resolution (HR) images. In order to deal with Gaussian blur, a local dictionary is generated and iteratively updated by K-means principal component analysis (K-PCA) and gradient decent (GD) to model the blur effect during the down-sampling. Compared with the state-of-the-art SR algorithms, the experimental results reveal that the proposed method can produce sharper boundaries and suppress undesired artifacts with the present of Gaussian blur. It implies that our method could be more effect in real applications and that the HR-LR mapping relation is more complicated than bicubic interpolation.

Published: May 2021

AbstractComputer vision is an interdisciplinary domain for object detection. Object detection relay is a vital part in assisting surveillance, vehicle detection and pose estimation. In this work, we proposed a novel deep you only look once (deep YOLO V3) approach to detect the multi-object. This approach looks at the entire frame during the training and test phase. It followed a regression-based technique that used a probabilistic model to locate objects. In this, we construct 106 convolution layers followed by 2 fully connected layers and 812 × 812 × 3 input size to detect the drones with small size. We pre-train the convolution layers for classification at half the resolution and then double the resolution for detection. The number of filters of each layer will be set to 16. The number of filters of the last scale layer is more than 16 to improve the small object detection. This construction uses up-sampling techniques to improve undesired spectral images into the existing signal and rescaling the features in specific locations. It clearly reveals that the up-sampling detects small objects. It actually improves the sampling rate. This YOLO architecture is preferred because it considers less memory resource and computation cost rather than more number of filters. The proposed system is designed and trained to perform a single type of class called drone and the object detection and tracking is performed with the embedded system-based deep YOLO. The proposed YOLO approach predicts the multiple bounding boxes per grid cell with better accuracy. The proposed model has been trained with a large number of small drones with different conditions like open field, and marine environment with complex background.

Authors: Yang Ya Ki 
Published: May 2021

Abstract
Background
The aim of this study was to develop a scale to measure patient safety care activities for clinical nurses and to verify validity and reliability it.

Methods
Literature review and expert consultation were utilized to develop the scale of the Patient Safety Care Activities. The validity and reliability analyses were conducted with 428 nurses working at 5 general hospitals. Exploratory factor analysis of the scale was performed, and convergent and discriminant validity as well as internal consistency reliability were determined.

Results
Eight subcategories (security, patient identification, operation (invasive procedure), medication, blood transfusion, management of infection, management of falls & sores, management of firefighting) with 44 items were validated to measure patient safety care activities. Convergent and discriminant validity indicated the applicability of the eight-factor Patient Safety Care Activities scale. The reliability of the Patient Safety Care Activities Scale was acceptable, with Cronbach’s a = .88 ~ .95.

Conclusion
The developed scale showed content, construct validity, and reliability, as well as convergent validity for each item and discriminant validity between the factors. This makes it suitable for use in a diverse range of future studies on patient safety care activity.

Published: May 2021

AbstractBackgroundNurturing students’ interest in science, technology, engineering, and mathematics (STEM) careers is a major goal of STEM education. Although the relationship between students’ stereotypical beliefs regarding STEM careers and their career interest can be reasonably hypothesized, research investigating the extent to which and how students’ STEM career interest is directly or indirectly influenced by their stereotypical beliefs is lacking. This study investigated how upper primary students’ stereotypical beliefs regarding STEM careers predicted their STEM self-efficacy and STEM career-related outcome expectations and how these constructs predicted their STEM career interest. Structural equation modelling was used to analyse quantitative survey data of 824 fourth- to sixth-grade students and test the hypothesized models.ResultsStudents’ stereotypical beliefs regarding STEM careers negatively predicted their self-efficacy in STEM activities and career-related outcome expectations. Additionally, the students’ self-efficacy in STEM activities and career-related outcome expectations in turn predicted their STEM career interest.ConclusionsThese results explain the potential indirect effect of STEM stereotypes on students’ career interest through self-efficacy and outcome expectations. The findings highlight the significant role of STEM stereotypes, self-efficacy in STEM activities, and career-related outcome expectations in students’ career development. The implications of this study for STEM education are also discussed.

Published: May 2021

AbstractBackgroundConcussion in sports has received a great deal of media attention and may result in short and longer-lasting symptoms, especially in adolescents. Although significant strides have been made in the identification and management of concussion, less is known about the primary prevention of this condition. The aims of this scoping review are to (1) summarize the current research of physical conditioning strategies to reduce or prevent concussion incidence in individuals participating in sport, especially adolescents, and (2) to identify gaps in the knowledge base. Our research question was what is known from the existing literature about physical preparation strategies to reduce or prevent concussion in adult and adolescent sports?MethodsThree literature searches were conducted by information officers at two universities at six-month intervals, using five electronic databases (PubMed;WorldCat.org; Mendeley; EBSCOHost and Ovid MEDLINE). To increase the search range, subject experts were consulted and articles and reference lists were hand searched. A scoping review methodology identified eligible studies that analyzed physical preparation techniques on modifiable physical risk factors in athletes to reduce the incidence of concussion. The PRISMA-ScR checklist guided the reporting of the findings.ResultsA total of 1414 possible articles were identified, after duplicates removed, and articles analyzed against the inclusion and exclusion criteria, only 9 articles qualified for analysis. Two articles were found from studying reference lists. Thus, a total of 11 articles were included in the final evaluation for the purposes of this study. Data are reported from mostly adolescent subjects participating in nine different sports from three countries. Findings are presented with specific reference to previously recognized modifiable risk factors of concussion which include neck strength, neck size, cervical stiffness, type of sport, and pre-activity exercises.ConclusionsThere is limited research examining the physical preparation of athletes, especially in adolescents, to reduce or prevent concussion, and conflicting evidence in the few small sample studies that were identified. This scoping review identifies the research gap for a potentially vital modifiable risk factor, notably in the physical preparation of children and adolescents to reduce or prevent sports-related concussion.

Published: May 2021

Abstract
Background
Implementation of best-practice care for patients with low back pain (LBP) is an important issue. Physiotherapists’ who hold unhelpful beliefs are less likely to adhere to guidelines and may negatively influence their patients’ beliefs. Pre-registration education is critical in moving towards a biopsychosocial model of care. This study aimed to investigate the changes in 2nd year physiotherapy students’ beliefs about LBP after a module on spinal pain management and determine whether these changes were maintained at the end of academic training.

Methods
During three consecutive calendar years, this longitudinal cohort study assessed physiotherapy students’ beliefs with the Back Pain Attitudes Questionnaires (Back-PAQ) in their 1st year, before and after their 2nd year spinal management learning module, and at the end of academic training (3rd year). Unpaired t-tests were conducted to explore changes in Back-PAQ score.

Results
The mean response rate after the spinal management module was 90% (128/143 students). The mean (± SD) Back-PAQ score was 87.73 (± 14.21) before and 60.79 (± 11.44) after the module, representing a mean difference of − 26.95 (95%CI − 30.09 to − 23.80, p < 0.001). Beliefs were further improved at the end of 3rd year (− 7.16, 95%CI − 10.50 to − 3.81, p < 0.001).

Conclusions
A spinal management learning module considerably improved physiotherapy students’ beliefs about back pain. Specifically, unhelpful beliefs about the back being vulnerable and in need of protection were substantially decreased after the module. Improvements were maintained at the end of academic training one-year later. Future research should investigate whether modifying students’ beliefs leads to improved clinical practice in their first years of practice.

Published: May 2021

Abstract
Background
The use of X-ray irradiation in the control of the maize weevil, Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae) infesting stored maize was tested at 60, 70 and 80 KeV as part of the international concerted efforts to save maize production and enhance food security. Investigations were done in the laboratory at mean temperature and relative humidity of 29.2 °C and 75.7%, respectively using three varieties of maize. The possibility that X-ray irradiation can affect the viability of maize grains when planted after weevil control process was also evaluated in the laboratory. Standard methods were used to achieve the specific objectives, and X-ray machine snap constituted the exposure time for each dose.

Results
The results revealed 10% mortality of adult weevils after 24 h and 40% mortality after a period of 7 days. The result indicates moderate effect on mortality. Progressive increase in mortality was recorded as dose increased from 60 to 80 KeV. X-ray irradiation at the doses tested did not significantly (P > 0.05) restrict S. zeamais emergence from maize grains and did not also significantly protect grains against damage and flour production. There was no difference in the pattern of daily emergence of new progenies and pattern of accumulated emergence. The relationship between X-ray irradiation doses and weight of emerging progenies require more specific analysis. Absence of significant difference between the viability of irradiated grains and un-irradiated grains strongly suggests that X-ray irradiation did not adversely affect seed viability, and this gives irradiation technique an opportunity of higher acceptability in agriculture.

Conclusions
We recommend > 80 KeV of X-ray irradiation or its incorporation into integrated pest management system in order to achieve effective post-harvest control of the pest.

AbstractBackgroundIn some localities of the Mediterranean coast and the Nile land region, the gall midgeSchizomyia buboniaeFrauenfeld, 1859 (Diptera: Cecidomyiidae) induce small barrel-shaped galls on the stem ofDeverra tortuosa(Desf.) DC. (Family: Apiaceae). Host plants interact with several insects in a different manner. The current work studies the interaction ofS. buboniaewithD. tortuosa. Furthermore, the present work predicted the distribution ofS. buboniaeand its host plantD. tortuosain Egypt by using MaxEnt modeling, in addition to the effect of elevation and vegetation cover on its distribution.ResultsThe predominance ofS. buboniaeoccurred during late winter to spring. TheS. buboniaelarvae are occasionally attacked by endoparasitoids of the genusInostemma(Platygastridae). There was a significant positive correlation between the number of galls per plant and the plant cover within the study localities. Meanwhile, there was no significant correlation between the number of galls per plant and the altitude within the study localities. Also, the high temperature and altitude were the most important predictors for the habitat distribution ofS. buboniaeand its host plantD. tortuosa. The predicted distribution range size forS. buboniaeis less than the total predicted distribution range size forD. tortuosa.ConclusionsThe current study suggests that the gall inducer prefers large plants more than small ones. The present study suggests that the habitat distribution patterns ofS. buboniaeand its host plantD. tortuosain Egypt can be modeled using a small number of occurrence records together with environmental variable layers for the study area through the maximum entropy modeling technique.

Published: May 2021

AbstractBackgroundThe primary objective of this study is to compare the effectiveness of the newborn’s penile block performed by the surgeon using the classical landmark method and the penile block performed by the anesthesiologist with ultrasound guidance.ResultsThis prospective, single-blinded, randomized clinical study included a total of forty newborn babies scheduled to undergo elective circumcision. The babies were randomized into two treatment groups of ultrasound (US)-guided penile block (group I; n = 20) and classical landmark method dorsal penile nerve block (DPNB) (group II; n = 20) group. Face, Legs, Activity, Cry, Consolability (FLACC) score was used to determine the block efficacy and postoperative pain and analgesic requirements. Intraoperative and postoperative FLACC scores, intraoperative analgesic needs, discharge time, complications, first oral intake time, and parent’s satisfaction were also recorded.FLACC scores were higher in group II than in group I during the intraoperative periods. Heart rate was higher in group II than in group I, at the incision, and during the procedure (P< 0.05). The number of patients requiring fentanyl was higher in group II than in group I (P< 0.01). FLACC scores were statistically higher in the landmark group at arrival in the PACU (P< 0.01) and after 30 min up to 2 h (P< 0.01). Parent’s satisfaction was significantly higher in US group (P< 0.01)ConclusionsIntraoperative analgesic needs and pain scores are lower in newborn babies who performed penile block with ultrasound-guided compared to the landmark method.
Can trace element supplementations (Cu, Se, and Zn) enhance human immunity against COVID-19 and its new variants?
Authors: Nedjimi Bouzid 
Published: May 2021

Abstract
Background
Coronavirus-19 (SARS-CoV-2) is constantly changed through mutation, and new stains of this virus are detected throughout the world such as B.1.1.7 (UK), B.1.351 (South Africa), and P.1 (Brazil). These strains seem to be more easily transmissible than other variants, which may lead to more cases and more deaths. Currently, there are many vaccines for SARS-CoV-2 available in the market but without full clinical data beside. Despite the existence of these vaccines, the numbers of outpatients are still increasing in many countries around the world, and the reliability of these vaccines still remains elusive. It is well known that trace element deficiencies increase the individual susceptibility to immune dysfunction and lead to global health problem. In this context, improving the immune defense system to combats this pandemic is absolutely necessary. The purpose of this review is to establish the probable relation between trace elements supplementation and COVID-19.

Main body
Several clinical studies confirmed that Cu, Se, and Zn insufficiencies alter the immune system and increase the vulnerability to viral infections. Based on antiviral and anti-inflammatory effects of these micronutrients, it seems logical that dietary supplementations of these components might enhance human immune system and lower the graveness of COVID-19 infection.

Conclusion
Based on available data, we hypothesize that the clinical use of some essential trace element supplementations such as copper, selenium, and zinc might be a preventive and promising option to enhance human immunity against the new pandemic COVID-19 and its new strains.

Published: May 2021

PURPOSE The COVID-19 pandemic has placed unprecedented demands on the health system. This led to delays in the initiation and completion of cancer treatment. We assessed the long-term health consequences because of the delay in diagnosis and treatment for cervical cancer due to COVID-19 in India. METHODS We used a Markov-model–based analysis assessing the lifetime health outcomes of the cohort of women population at risk from cervical cancer in India. The decrease in survival for those with the treatment interruption was calculated based on the number of days the treatment was extended beyond the standard duration. Furthermore, to model the impact of late diagnosis and delayed treatment initiation, the patients were assumed to have upstaged during the delay period, as per natural progression of disease. RESULTS We estimate 2.52% (n = 795) to 3.80% (n = 2,160) lifetime increase in the deaths caused by cervical cancer with treatment restrictions ranging from 9 weeks to 6 months, respectively, as compared to no delay. On the contrary, 88-238 deaths because of COVID-19 disease are estimated to be saved during this restriction period among the patients with cervical cancer. Overall, the excess mortality because of cervical cancer led to 18,159-53,626 life-years being lost and an increase of 16,808-50,035 disability-adjusted life-years. CONCLUSION Delays in diagnosis and treatment are likely to lead to more cervical cancer deaths as compared to COVID-19 mortality averted among the patients with cervical cancer. Health systems must reorganize in terms of priority setting for provision of care, starting with prioritizing the treatment of patients with early-stage cervical cancer, increasing use of teleconsultation, and strengthening the role of primary care physicians in provision of cancer care.
