Implementing the Protocol of Perioperative Narrow-spectrum Antibiotic Prophylaxis in the Surgical Wards of Mofid Children’s Hospital in 2019 - 2020, A Comparative Study

Background: Surgical procedures may be complicated by post-surgical infections. This study investigates the role of administering perioperative narrow-spectrum antibiotic prophylaxis in preventing post-surgical infections as compared to routine broad-spectrum antibiotic usage in the surgical ward. Methods: Narrow-spectrum perioperative antibiotic prophylaxis, in accordance with CDC guidelines, was implemented in our hospital in October 2019. In this quasi-experimental study, all the children (one month to fifteen years old) who underwent surgery from April to September 2019 and had received broad-spectrum antibiotics for various durations, as well as those operated after the implementation of the perioperative narrow-spectrum antibiotic prophylaxis plan (October 2019 to March 2020) were enrolled. Surgical wound type (clean, clean/contaminated, contaminated, and dirty), type and site of the infection, and the patient’s age and sex were recorded. Cases with postoperative infections were followed up in the two groups during hospitalization and for 30 days (or 90 days if a prosthetic material was implanted) after discharge. The rate of post-surgical infections was compared between the two groups by the Mann-Whitney and Chi-squared tests. Results: In total, 4308 cases were enrolled in the first six months and 3650 in the second six months of the study. The rate of post-surgical infections in the first group was 31/4380 (23.7%) as compared to 22/3650 (20%) in the second group (P-value = 0.3365) Conclusions: There was no increase in the frequency of post-surgical infections after the implementation of the perioperative narrow-spectrum antibiotic prophylaxis protocol. Reducing the use of antibiotics before surgery shrinks costs and antibiotic resistance without any effect on the post-surgical infection rate.
Social and Emotional Characteristics of Speech-based In-Vehicle Information Systems: Impact on Attitude and Driving Behaviour

Modern vehicles use advanced information systems in vehicles to provide and control a wide variety of functions and features. Even modest vehicles today are equipped with systems that control diverse functions from air-conditioning to high quality audio/video systems. Since driving requires the use of eyes and hands, voice interaction has become more widely used by in-vehicle systems. Due to the technical complexity involved in voice recognition, focus has been on issues of speech ecognition. Speech generation is comparatively simple, but what effect does the choice of voice have on the driver? We know from human-human interaction that social cues of the voice itself influence attitude and interpretation of information. Introducing speech based communication with the car changes the relationship between driver and vehicle. So, for in-vehicle information systems, does the spoken voice matter? The work presented in this thesis studies the effects of the voice used by invehicle systems. A series of studies were used to answer the following questions: Do the characteristics of voices used by an in-vehicle system affect driver's attitude? Do the characteristics of voice used by an in-vehicle system affect driver's performance? Are social reactions to voice communication the same in the car environment as in the office environment? Results show that voices do matter! Voices trigger social and emotional effects that impact both attitude and driving performance. Moreover, there is not one effective voice that works for all drivers. Therefore an in-vehicle system that knows its driver and possibly adapts to its driver can be the most effective. Finally, an interesting observation from these studies is that social reactions to voice communication in the car are different than in the office, Similarity attraction, an otherwise solid finding in social science, did not hold all studies. It is hypothesized that this difference can be related to the different kinds of task demands when driving a car or working in an office environment (A). http://urn.kb. se/resolve? urn=urn:nbn:se:liu:diva-51969.
A novel and compact optical polarizer incorporating a layered waveguide core structure

A compact optical polarizer based on a directional coupler incorporating layered waveguide core structures is studied in detail in this paper. Important waveguide design parameters such as the guide width, guide separation, guide height, refractive index contrast, and wavelength dependence have been analyzed by using the vectorial H-field finite-element method. The optical power transfer characteristics have been calculated by using the least squares boundary residual methods.
Messaging in the Malaysian Workplace: Communication, Social Media and Employee Wellbeing

This article attempts to identify the impact of social media and new messaging processes on the well-being of Malaysian workers (specifically middle managers). It explores Malaysian workplace use of electronic communication methods and how managers view the impact of tablets, social networking apps and similar technologies on their social and emotional well-being, including their capacity to relate to and interact with other employees. In the Malaysian capital Kuala Lumpur, 27 middle managers were interviewed in five focus groups, with the middle managers representing various public and private sector organizations. The findings reveal that social media and e-mail dominate workplace communication among these Kuala Lumpur–based managers; emotional and mental health concerns (like pressure to be constantly available) for themselves and the people they managed motivated some middle managers to preference face-to-face interaction. This was particularly true of certain contexts, like when providing one-on-one feedback on performance. The past decade has seen the widespread and rapid adoption of social media, messaging and other communication technologies in the workplace. It is hoped that this study contributes to an understanding of the impact of this change on employee well-being in Malaysia.

Mindfulness and Mental Health

attention to the internal and external experiences occurring in the present moment, and is often taught through a variety of meditation exercises’1. It includes a kind of meta-awareness, self regulation of attention (to immediate experience) and a certain mindset e.g. being non-reactive, non-judgemental and accepting. This practice has been derived from Buddhism which originated in India in the 6th Century BC2. The Four Noble Truths in Buddhism include the presence of suffering (Diagnosis), its cause (Aetiology), that it can be ended (Prognosis) and the Eight-Fold Noble Path (Prescription). The Eight-Fold Noble Path includes Right Speech, Right Action, Right Livelihood, Right Effort, Right Mindfulness (Sati), Right Concentration, Right Aspiration, and Right View. Mindfulness is also one of the seven factors of enlightenment. These include Mindfulness, Investigation of reality, Energy, Rapture, Tranquility, Concentration and Equanimity. Mindfulness in the Buddhist practice is like overseeing a situation (for example, a cowherd sits in a relaxed manner and watches his cows over a distance). In the practice of mindfulness there is also a sense of restraint i.e. bare attention and avoiding to get carried away by associations, projections, evaluations, proliferations etc (distractions); focus on here and now and on being non-judgemental. There should be no craving, ill will or ignorance regarding the object of mindfulness. In order to practice or develop mindfulness one could focus on body e.g. breath, posture etc.; sensations or feelings; mind (Chitta) e.g. mental states; and phenomena (Dhammas) e.g. hindrances and aggregates.

Occurrence of eyespot of cereals in Tunisia and identification of Oculimacula species and mating types

Abstract The objectives of this study were to investigate the occurrence of eyespot in commercial spring cereal crops in four climatic areas in Tunisia and characterize the dominant species of Oculimacula responsible for the disease. A total of 294 wheat, barley and oat fields were surveyed for eyespot incidence and severity during four cropping seasons from 2010 to 2014. Eyespot was identified in 63.5% of the fields with an average incidence of 23.1% infected stems. The number of infected fields as well as the incidence and severity of disease increased significantly during the 5 years of the study. A significant difference in the occurrence of eyespot among the climatic regions was noted with the wetter areas having greater disease incidence. The highest incidence of eyespot was recorded in durum wheat and bread wheat fields, whereas barley was significantly less infected. The effect of previous crop on eyespot incidence was not significant. All 70 isolates collected in this study were identified as O. yallundae and among them, 39 were identified as MAT1-2 and 31 as MAT1-1. This study highlights the influence of climatic conditions on the distribution of eyespot in the cereal growing areas of Tunisia as well as the increasing occurrence of the disease. The predominance of O. yallundae is an important consideration in the choice of integrated management strategies for eyespot. The presence of both mating types of O. yallundae in similar proportions suggests that sexual reproduction may be occurring.
Managerial Challenges Impacting on a TBM Design: A Kingdom of Saudi Arabia Metro Project

This paper explores the managerial challenges and viewpoints relating to the management of a metro design in KSA, raised by a group of design engineering staff. The paper examines the scope, reflections, and attitudes to the project management and which appear to contribute to the efficacy of the design outcomes between a single group of engineering personnel of thirteen (13) design engineers for a metro development in KSA. The paper advances a conceptualisation from the findings of a diverse range of qualitative personnel opinion into an integrated framework. Outcomes from this inquiry suggests that the project management show clear issues with the management style adopted to manage this group and explores the derived themes of namely four (4) main themes, namely Management; Project, People; and Technology. The outcomes shows opinion that the project management are not effectively managing the project corresponding with raised issues of cost/schedule overruns, delays to the project through poor coordination, ineffective leadership of the projects activities, and inadequate project preparation and its managerial execution. The paper further suggests how some of the effects of these identified issues may be reduced or mitigated.
Intelligent sensory technology for health-monitoring-based maintenance of infrastructures

In order to maintain sustainability of infrastructures in which have significant influence to social lifelines, an economical and rational maintenance management system is absolutely needed. Maintenance management of infrastructures and reduction of their life cycle cost (LCC), become serious problems those have to be solved urgently. In this paper, Structural health monitoring based maintenance (SHMBM) aimed to reduce structure’s life cycle cost is proposed. Theoretical background of SHMBM and contribution of monitoring information in LCC reduction are reviewed. As the tools to retrieve the structural deformational properties information, the intelligent sensory principles and their sensory system are introduced such as GPS based MMS monitoring technology, peak memory sensory technology, elasto-magnetic sensory technology and fiber optical sensory technology. Their reliabilities were verified by some verification test and field application test. Some examples of SHMBM application in the monitoring of structural properties are also described as well.
Development of Micro Separation Technology Modules. Part 1: Liquid‐Liquid Extraction

While devices based on micro effects are increasingly accepted in reaction engineering, there is still no breakthrough for separation applications like liquid-liquid extraction (LLE). This situation results from process design concepts which rely mostly on empirical work, involving high experimental effort and cost. Additionally, the limited throughput potential, mostly caused by complex fluid dynamics and difficult phase separation, is problematic. In this work the current state and potential of micro technology for LLE is discussed based on literature data. Afterwards, process simulations with a distributed plug flow model are used to access the specific advantages of this technology and to identify critical process parameters.
Temperature and dIDS/dt Dependence of the Switching Energy of SiC Schottky Diodes in Clamped Inductive Switching Applications

This paper presents the temperature and switching rate dependence of 1.2 kV/30 A SiC Schottky diode energy losses in clamped inductive switching circuits with 1.2 kV/30 A SiC MOSFETs as the switching transistors. The devices are tested under an ambient temperature range that spans from -75°C to 175°C and with switching rates that span from 10 to 100 A/μs. Due to the abruptness of the diode turn-OFF, low series resistance and the lack of reverse recovery, SiC SBDs are known to exhibit ringing or electromagnetic oscillations in the presence of parasitic inductances and high switching rates. The impact of these electromagnetic oscillations on the switching energy, the dependence of the switching energy on temperature and the switching rate (dIDS/dt) is the purpose of this paper’s investigation.
Aerodynamic forces on fixed and rotating plates

Pressure measurements on static and autorotating flat plates have been recently reported by Lin et al. (2006), Holmes, et al. (2006), and Richards, et al. (2008), amongst others. In general, the variation of the normal force with respect to the angle of attack appears to stall in the mid attack angle range with a large scale separation in the wake. To date however, no surface pressures have been measured on auto-rotating plates that are typical of a certain class of debris. This paper presents the results of an experiment to measure the aerodynamic forces on a flat plate held stationary at different angles to the flow and allowing the plate to auto-rotate. The forces were determined through the measurement of differential pressures on either side of the plate with internally mounted pressure transducers and data logging systems. Results are presented for surface pressure distributions and overall integrated forces and moments on the plates in coefficient form. Computed static force coefficients show the stall effect at the mid range angle of attack and some variation for different Reynolds numbers. Normal forces determined from autorotational experiments are higher than the static values at most pitch angles over a cycle. The resulting moment coefficient does not compare well with current analytical formulations which suggest the existence of a flow mechanism that cannot be completely described through static tests.
A compact circular‐ring antenna for ultra‐wideband applications

A simple circular‐ring planar‐monopole antenna, with a compact size of 26 × 28 mm2, fed by an offset‐microstrip line, is proposed. The antenna is composed of a circular‐ring radiator and a ground plane with a small rectangular slot cut along the upper edge for ultra‐wideband (UWB) operation. Studies of the antenna are carried out using computer simulation. Prototype of the antenna is used for verification of the simulation results. Results show that the antenna has an impedance bandwidth of more than 132% (from 3.7 to more than 18 GHz) for the standing wave ratio of less than 2 (voltage standing wave ratio, VSWR ≤ 2), a stable omnidirectional radiation pattern and an average peak gain of 3.97 dBi across the UWB, making the antenna a good candidate for use in UWB communications. © 2011 Wiley Periodicals, Inc.

Dream It, Do It? Associations between Pornography Use, Risky Sexual Behaviour, Sexual Preoccupation and Sexting Behaviours among Young Australian Adults

While sexting behaviours have attracted increasing research focus over the last decade as both normative and deviant forms of sexual activity, little attention has been paid to their potential associations with sexual preoccupation and heightened interest in sex. The current study sought to identify whether sexual preoccupation significantly predicts sending, receiving, and disseminating sexts, after controlling for pornography use and risky sexual behaviours. Young Australian adult participants (N = 654, 78.8% women) aged 18 to 34 (M = 19.78, SD = 1.66) completed an anonymous online self-report questionnaire regarding their engagement in sexting behaviours (sending, receiving, and dissemination), pornography use, risky sexual behaviours, and sexual preoccupation. Results showed that individuals with higher sexual preoccupation were more likely to engage in pornography use and risky sexual behaviours. Binary hierarchical logistic regressions revealed that sexual preoccupation predicted higher rates of sending and receiving sexts. However, sexual preoccupation did not significantly contribute to increased rates of sext dissemination. Our study illustrates the need to incorporate pornography viewing and sexting into the promotion of safe sexual behaviours in online and offline contexts, and the potential to utilise modern technology to negotiate safer sex practices.
Resolution-Enhanced Parallel Coded Ptychography for High-Throughput Optical Imaging

Ptychography is an enabling coherent diffraction imaging technique for both fundamental and applied sciences. Its applications in optical microscopy, however, fall short for its low imaging throughput and limited resolution. Here, we report a resolution-enhanced parallel coded ptychography technique achieving the highest numerical aperture and an imaging throughput orders of magnitude greater than previous demonstrations. In this platform, we translate the samples across the disorder-engineered surfaces for lensless diffraction data acquisition. The engineered surface consists of chemically etched micron-level phase scatters and printed sub-wavelength intensity absorbers. It is designed to unlock an optical space with spatial extent (x, y) and frequency content (kx, ky) that is inaccessible using conventional lens-based optics. To achieve the best resolution performance, we also report a new coherent diffraction imaging model by considering both the spatial and angular responses of the pixel readouts. Our low-cost prototype can directly resolve 308-nm linewidth on the resolution target without aperture synthesizing. Gigapixel high-resolution microscopic images with a 240-mm2 effective field of view can be acquired in 15 seconds. For demonstrations, we recover slow-varying 3D phase objects with many 2π wraps, including optical prism and convex lens. The low-frequency phase contents of these objects are challenging to obtain using other existing lensless techniques. For digital pathology applications, we perform accurate virtual staining by using the recovered phase as attention guidance in a deep neural network. Parallel optical processing using the reported technique enables novel optical instruments with inherent quantitative nature and metrological versatility.

A high-density, four-channel, OEIC transceiver module utilizing planar-processed optical waveguides and flip-chip, solder-bump technology

An optoelectronic transceiver module is described consisting of a four-channel AlGaAs integrated laser/monitor transmitter and a four-channel GaAs MESFET integrated detector/preamp receiver. The optoelectronic chips are flip-chip, solder-bump bonded to a substrate containing electrical wiring and planar-processed optical waveguides. The optical waveguide layer serves two purposes: the routing of optical signals, as well providing mechanical registrations for the optoelectronic chips and fiber-optic ribbon connector. The work described here demonstrates one approach to high-density, optoelectronic array packaging compatible with existing high-performance electronic packaging technology. >
