Effect Of Using Computers In Teaching First Grade Deaf Children In United Arab Emirates

The study is based on a joint small research project between two teachers of children who are categorized as Deaf, willing to undergo an action research process to develop their own teaching and to take part in a pioneering experiment, and two researchers/academics from the Department of Special Education at the United Arab Emirates University. The main idea of the study was to examine the assumption that using computer in teaching deaf and those with hard of hearing children results in better performance than using traditional methods of education with no access to computers when teaching a standard subject. The concerned students were educated full time at a center for rehabilitation in one of the UAE cities. Computers were never used in the center for planned teaching purposes for individual subjects. The research sample was determined out of a well-studied research community as 12 students (all boys). Students were divided into two groups, experimental, and controlled. Each of the two groups consisted of six students. A program was developed by the two researchers and experimentally administered on a group of deaf students with support of the two class teachers. The program was applied on first grade school children only who attend the center in single gender classrooms at the United Arab Emirates. It is hoped that the finding of this research would help all concerned with the education of deaf/hard of hearing students within and outside of the UAE.
Standardised mortality ratios as a user-friendly performance metric and trigger for quality improvement in a Flemish hospital network: multicentre retrospective study

Objective To illustrate the development and use of standardised mortality rates (SMRs) as a trigger for quality improvement in a network of 27 hospitals. Design This research was a retrospective observational study. The primary outcome was in-hospital mortality. SMRs were calculated for All Patient Refined—Diagnosis-Related Groups (APR-DRGs) that reflect 80% of the Flemish hospital network mortality. Hospital mortality was modelled using logistic regression. The metrics were communicated to the member hospitals using a custom-made R-Shiny web application showing results at the level of the hospital, patient groups and individual patients. Experiences with the metric and strategies for improvement were shared in chief medical officer meetings organised by the Flemish hospital network. Setting 27 Belgian hospitals. Participants 1 198 717 hospital admissions for registration years 2009–2016. Results Patient gender, age, comorbidity as well as admission source and type were important predictors of mortality. Altogether the SMR models had a C-statistic of 88%, indicating good discriminatory capability. Seven out of ten APR-DRGs with the highest percentage of hospitals statistically significantly deviating from the benchmark involved malignancy. The custom-built web application and the trusted environment of the Flemish hospital network created an interoperable strategy to get to work with SMR findings. Use of the web application increased over time, with peaks before and after key discussion meetings within the Flemish hospital network. A concomitant reduction in crude mortality for the selected APR-DRGs from 6.7% in 2009 to 5.9% in 2016 was observed. Conclusions This study reported on the phased approach for introducing SMR reporting to trigger quality improvement. Prerequisites for the successful use of quality metrics in hospital benchmarks are a collaborative approach based on trust among the participants and a reporting platform that allows stakeholders to interpret and analyse the results at multiple levels.
A Novel Message-Preserving Scheme with Format-Preserving Encryption for Connected Cars in Multi-Access Edge Computing

In connected cars with various electronic control unit (ECU) modules, Ethernet is used to communicate data received by the sensor in real time, but it is partially used alongside a controller area network (CAN) due to the cost. There are security threats in the CAN, such as replay attacks and denial-of-service attacks, which can disrupt the driver or cause serious damage, such as a car accident through malicious manipulation. Although several secure protocols for protecting CAN messages have been proposed, they carry limitations, such as combining additional elements for security or modifying CAN messages with a limited length. Therefore, in this paper, we propose a method for encrypting the data frame, including real data in the CAN message structure, using format-preserving encryption (FPE), which ensures that the plaintext and ciphertext have the same format and length. In this way, block ciphers such as AES-128 must be divided into two or three blocks, but FPE can be processed simultaneously by encrypting them according to the CAN message format, thus providing better security against denial-of-service attacks. Based on the 150 ms CAN message, a normal message was received from a malicious message injection of 180 ms or more for AES-128 and a malicious message injection of 100 ms or more for FPE. Finally, based on the proposed scheme, a CAN transmission environment is constructed for analyzing the encryption/decryption rate and the process of transmitting and processing the encrypted message for connected cars in multi-access edge computing (MEC). This scheme is compared with other algorithms to verify that it can be used in a real environment.
Support for Electronic Health Records in Czech Law

The spreading use of the e-Health applications in healthcare raises questions about the legal aspects of this development. In this paper, we wanted to look into such questions related to one of the most basic elements of any e-Health solution - electronic health records - in Czech law. The article aimed to create a review of the national legislation related to electronic health records currently in force (which means primarily the Care for Health of the People Act n. 20/1966 Sb.), and to identify possible legal issues that could be preventing the deployment of e-Health Applications. The article shows that the Czech law indeed allows usage of electronic health records, and sets relatively detailed rules in some areas such as what information must be included inside it, and how to archive the data. However, it offers little guidance regarding some other situations, like it is ignoring the question of technical standards for interoperability. The briefness of the Act leaves lot of the decisions related to the development of the e-Health applications up to the individual healthcare facilities.
Blood Biomarkers of Recovery Efficiency in Soccer Players

Physical exercise strongly affects human metabolism and causes biochemical changes. This study aimed to investigate the relationship between routine plasma biomarker levels and recovery efficiency in soccer players during an entire competitive match season. The players participating in the study were divided into a midfielder/defender group (seven midfielders and seven defenders) and a goalie/substitute group (six persons—goalkeepers and players with a short cumulative match-time). The fasting capillary blood samples were taken 17–24 h after each competitive match. The blood plasma was used to determine the creatinine, urea, alkaline phosphatase, creatine kinase, lactate dehydrogenase, aspartate and alanine aminotransferase, iron and magnesium levels of the athletes. The levels of (AST) (aspartate aminotransferase), (ALT) (alanine aminotransferase) and (Cr) creatinine were higher in the midfielder/defender group than in the control group, but only AST and Cr significantly varied over time (AST decreased, and Cr increased with time). The (LDH) (lactate dehydrogenase) activity and urea level were significantly lower in the midfielder/defender group than in the goalie/substitute group, and it significantly varied over time (LDH decreased, and urea increased with time). No differences in the (CK) creatine kinase and (ALP) alkaline phosphatase activities between the groups was found, although CK increased significantly with time in the midfielder/defender group (particularly midfielders in the spring round). In midfielders, the AST activity and the iron level were significantly lower in the spring than in the autumn round. On the contrary, ALT, CK, urea and magnesium levels were significantly higher in the spring than in autumn round. A long-term measurement of biochemical parameters in elite soccer players indicated that AST, CK, LDH and creatinine levels, when analyzed together, could constitute a useful set of markers for monitoring recovery periods.
Predicting miRNA-Disease Associations by Incorporating Projections in Low-Dimensional Space and Local Topological Information

Predicting the potential microRNA (miRNA) candidates associated with a disease helps in exploring the mechanisms of disease development. Most recent approaches have utilized heterogeneous information about miRNAs and diseases, including miRNA similarities, disease similarities, and miRNA-disease associations. However, these methods do not utilize the projections of miRNAs and diseases in a low-dimensional space. Thus, it is necessary to develop a method that can utilize the effective information in the low-dimensional space to predict potential disease-related miRNA candidates. We proposed a method based on non-negative matrix factorization, named DMAPred, to predict potential miRNA-disease associations. DMAPred exploits the similarities and associations of diseases and miRNAs, and it integrates local topological information of the miRNA network. The likelihood that a miRNA is associated with a disease also depends on their projections in low-dimensional space. Therefore, we project miRNAs and diseases into low-dimensional feature space to yield their low-dimensional and dense feature representations. Moreover, the sparse characteristic of miRNA-disease associations was introduced to make our predictive model more credible. DMAPred achieved superior performance for 15 well-characterized diseases with AUCs (area under the receiver operating characteristic curve) ranging from 0.860 to 0.973 and AUPRs (area under the precision-recall curve) ranging from 0.118 to 0.761. In addition, case studies on breast, prostatic, and lung neoplasms demonstrated the ability of DMAPred to discover potential disease-related miRNAs.
Conversion of Black Carbon Emitted from Diesel-Powered Merchant Ships to Novel Conductive Carbon Black as Anodic Material for Lithium Ion Batteries

Waste soot generated from diesel engine of merchant ships has ≥ 2 µm agglomerates consisting of 30–50 nm spherical particles, whose morphology is identical to that of carbon black (CB) used in many industrial applications. In this study, we crystallized waste soot by heat treatment to transform it into a unique completely graphitic nano-onion structure, which is considerably different from that of commercial conductive CB. While commercial CB has a large specific surface area because of many surface micropores generated due to quenching by water-spraying in the production process, the heat-treated waste soot has a smooth micropore-free surface. Thus, the treated waste soot acquires the shape of CB but has a much smaller specific surface area. When the treated soot is used as a conductive material in lithium ion battery (LIB) half cells, the Coulombic efficiency of the entire anode is improved significantly owing to its low specific surface area; the electrochemical performance of the LIB is considerably enhanced compared to that of conventional conductive materials. Thus, polluting soot generated in marine propulsion can be transformed into a new class of CB with a unique structure by simple heat treatment; this soot can also be used as an inexpensive conductive material to enhance the LIB performance.
Inhibition of Rho GTPases in Invertebrate Growth Cones Induces a Switch in Responsiveness to Retinoic Acid

During development, growth cones are essential for axon pathfinding by sensing numerous guidance cues in their environment. Retinoic acid, the metabolite of vitamin A, is important for neurite outgrowth during vertebrate development, but may also play a role in axon guidance, though little is known of the cellular mechanisms involved. Our previous studies showed that retinoid-induced growth cone turning of invertebrate motorneurons requires local protein synthesis and calcium influx. However, the signalling pathways that link calcium influx to cytoskeletal dynamics involved in retinoid-mediated growth cone turning are not currently known. The Rho GTPases, Cdc42 and Rac, are known regulators of the growth cone cytoskeleton. Here, we demonstrated that inhibition of Cdc42 or Rac not only prevented growth cone turning toward retinoic acid but could also induce a switch in growth cone responsiveness to chemorepulsion or growth cone collapse. However, the effects of Cdc42 or Rac inhibition on growth cone responsiveness differed, depending on whether the turning was induced by the all-trans or 9-cis retinoid isomer. The effects also differed depending on whether the growth cones maintained communication with the cell body. These data strongly suggest that Cdc42 and Rac are downstream effectors of retinoic acid during growth cone guidance.
Lay People Esthetic Evaluation of Primary Surgical Repair on Three-Dimensional Images of Cleft Lip and Palate Patients

Background and Objectives: Previous literature has disclosed that facial attractiveness affects the esthetic evaluation of nose and lip deformity on frontal and lateral photographs. However, it has never been debated if the removal of the external facial features on three-dimensional (3D) models (“cropped assessment bias”) could provide a considerable usefulness in the interpretation and comparison of the results. Additionally, it has been assumed on two-dimensional (2D) studies that esthetic assessment biases with respect to observer gender, and it is not acknowledged if and to the extent that “gender assessment bias” may be influenced by a three-dimensional layout. The aim of this study is to investigate if facial traits and observers’ gender may affect the esthetic ratings of unilateral cleft lip and palate (UCLP) patients after soft tissue reconstruction. Materials and Methods: Three-dimensional images of ten UCLP patients’ images were acquired before the intervention (T0), one-month (T1) and six-months (T2) postoperative. Geomagic® software (version 2014; 3D Systems, Rock Hill, SC, USA) was used to remove the external facial features of 3D surface models. Five-point scale developed by Asher-McDade et al. was used to rate both nasolabial attractiveness and impairment for full-face (FF) and cropped-face (CF) 3D images. Forty-three judges (21 males, 22 females) were enrolled for the esthetic evaluation. Intraclass correlation coefficient (ICC) was used to test intra- and inter-examiner reliability; a value of 0.7 was set as the minimum acceptable level of reliability. Results: When comparing the 2 sets of observations (FF and CF), the ICC ranged from 0.654 to 0.823. Concerning gender assessment bias, the ICC ranged from 0.438 to 0.686 and from 0.722 to 0.788 for males and females, respectively. Concerning inter-examiner reliability, ICC for questions 2–7 ranged from 0.448 to 0.644 and from 0.659 to 0.817 at T0 and T2, respectively. Conclusions: The removal of external facial features provides subtle differences on the esthetic assessment of UCLP patients. Moreover, based on our data, examiners’ gender differences may affect esthetic assessment of UCLP patients. Despite the subjectivity of esthetic judgments, a reliable, validated and reproducible scoring protocol should consider the influence of gender differences on 3D esthetic assessment of UCLP patients.
Assessment of Occupational Safety and Hygiene Perception among Afro-Caribbean Hair Salon Operators in Manchester, United Kingdom

Because of exposure to a number of potential health hazards within the work environment, hairstylists experience occupational diseases that include occupational asthma, skin conditions and musculoskeletal diseases. The paucity of studies assessing occupational safety and hygiene management among Afro-Caribbean hair salon operators in the UK promoted the study. QualtricsTM was used to assess the participants’ perception of exposure to hair products and their personal safety and hygiene knowledge, attitudes, awareness, and risk perceptions at work. In five salons, indoor air quality was monitored over one working week for selected environmental pollutants: temperature, humidity, CO, CO2 and Total Volatile Organic Compounds (TVOCs) using a GrayWolf Direct Sense Indoor Air Quality-IAQ (IQ-610). The use of unflued gas heating to raise the indoor temperature was common among the salons’ operators which explains the high carbon monoxide readings recorded. Itchy eyes and nose (44.4%) shoulder, neck and back pain (39.2%) were frequently reported. Age-stratified analysis of reported occupational ailments showed participants within an age bracket of 31–35 reported allergies (24%) and itchy eyes and nose (19.1%) as the most common of occupational ailments. Respiratory, skin and musculoskeletal symptoms ranked as major occupational ill-health experiences among the study population. The study outcome demonstrated that the type of activity and the hair products used play an important role in the level of pollutants in the working environment. The substitution of the more harmful hair products with safer alternatives is needed, as is the encouragement of health surveillance.

Glucose triggers strong taxon-specific responses in microbial growth and activity: insights from DNA and RNA qSIP.

Growth of soil microorganisms is often described as carbon limited, and adding labile carbon to soil often results in a transient and large increase in respiration. In contrast, soil microbial biomass changes little, suggesting that growth and respiration are decoupled in response to a carbon pulse. Alternatively, measuring bulk responses of the entire community (total respiration and biomass) could mask ecologically important variation among taxa in response to the added carbon. Here, we assessed taxon-specific variation in cellular growth (measured as DNA synthesis) and metabolic activity (measured as rRNA synthesis) following glucose addition to soil using quantitative stable isotope probing with H2 18 O. We found that glucose addition altered rates of DNA and rRNA synthesis, but the effects were strongly taxon-specific: glucose stimulated growth and rRNA transcription for some taxa, and suppressed these for others. These contrasting taxon-specific responses could explain the small and transient changes in total soil microbial biomass. Responses to glucose were not well predicted by a priori assignments of taxa into copiotrophic or oligotrophic categories. Across all taxa, rates of DNA and rRNA synthesis changed in parallel, indicating that growth and activity were coupled, and the degree of coupling was unaffected by glucose addition. This pattern argues against the idea that labile carbon addition causes a large reduction in metabolic growth efficiency; rather, the large pulse of respiration observed with labile substrate addition is more likely to be the result of rapid turnover of microbial biomass, possibly due to trophic interactions. Our results support a strong connection between rRNA synthesis and bacterial growth, and indicate that taxon-specific responses among soil bacteria can buffer responses at the scale of the whole community.

Why Singles Prefer to Retire Later

This study goes beyond a purely financial perspective to explain why single older workers prefer to retire later than their partnered counterparts. We aim to show how the work (i.e., its social meaning) and home domain (i.e., spousal influence) contribute to differences in retirement preferences by relationship status. Analyses were based on multiactor data collected in 2015 among older workers in the Netherlands (N = 6,357) and (where applicable) their spouses. Results revealed that the social meaning of work differed by relationship status but not always as expected. In a mediation analysis, we found that the social meaning of work partically explained differences in retirement preferences by relationship status. We also show that single workers preferred to retire later than workers with a “pulling” spouse, earlier than workers with a “pushing” spouse, and at about the same time as workers with a neutral spouse.
