Work integrated learning in the space of nursing informatics is a new concept in Australian nursing curriculum. This study examined nursing students' experiences in the pilot nursing informatics clinical placement centered on electronic medical records, their use in patient care and clinical decision making. Students completed reflective diaries of their learning during the four-week placement. Data was explored by thematic analysis. Emergent themes included: importance of adequate training in using EMR; impact of EMR on nursing workflow and patient care; shaping future career choices; forming rewarding relationships; and potential for improvements. These themes will be used to enhance teaching and learning opportunities as this pilot placement evolves into permeant part of the nursing curriculum.
Requirement Engineering Practices in Pakistan Software Industry: Major Problems

Requirement engineering is now an essential practice performed in almost every software manufacturing industry around the globe. It increases the amount of project success in a greater way. Sometimes this could be a labelled activity or sometimes not. However, almost every software development environment across the world is using some sort of basic requirement engineering process now days. The situation is not different in a developing country like Pakistan. A good number of software industries are following standard requirement engineering practices completely or partially. There are multiple reasons behind partial implementation such as lack of knowledge about processes, cost in terms of time and money and implementation of processes. In our study, we have collected factual data regarding current requirement engineering practices from Pakistan software industry. We have studied the organizations of varying size and types of projects. We also find out their success rate and problems which are due to partial or wrong implementation of requirement engineering practices. We are hopeful that this study will provide a cost effective solution for improving requirement engineering practices in Pakistan industry.
Urbanization-induced environmental changes strongly affect wetland soil bacterial community composition and diversity

Soil microbial communities potentially serve as indicators for their responses to changes in various ecosystems at scales from a region to the globe. However, changes in wetland soil bacterial communities and how they are related to urbanization intensities remains poorly understood. Here, we collected 60 soil samples along urbanization intensity gradients from 20 wetlands. We measured a range of environmental factors and characterized bacterial communities structure using 16S ribosomal RNA (16S rRNA) gene amplicon sequencing that targeted the V4-V5 region. Our results revealed the dominant soil bacterial phyla included Proteobacteria (39.3%), Acidobacteria (21.4%) and Chloroflexi (12.3%) in the wetlands, and showed a significant divergence of composition in intensive urbanization area (UI_4) than other places. A critical ‘threshold’ exists in the soil bacterial diversity, demonstrating different patterns: a gradual increase in the areas of low-to-intermediate disturbances but a significant decrease in highly urbanized areas where metabolic functions were significantly strong. Additionally, soil pH, total phosphorus (TP), available phosphorus (AP) and ammonia nitrogen (NH4 +-N) made a significant contribution to variations in bacterial communities, explaining 49.6%, 35.1%, 26.2% and 30.7% of the total variance, respectively. pH and NH4 +-N were identified as the main environmental drivers to determine bacterial community structure and diversity in the urban wetlands. Our results highlight collective changes in multiple environmental variables induced by urbanization rather than by the proportion of impervious surface area (ISA), which were potentially attributed to the spatial heterogeneity along different urbanization gradients.

TQM and the cost of environmental quality

Because management is driven largely by financial concerns, determining the cost of environmental quality is a critical step in developing an environmental TQM program for which management will actively demonstrate commitment and support. Costs of environmental quality can be grouped into three categories: failure, prevention, and appraisal. The total cost of environmental quality can be used as a benchmark to monitor the level of environmental quality and to justify the redirection of resources.
Verification of a building defect classification system for housing

Purpose – This paper seeks to verify and validate a building defect classification system that has been previously developed and presented in Structural Survey. In doing so, the paper also seeks to address the following question: “Can Government regulatory control improve the quality of house construction? ”Design/methodology/approach – Archicentre House Inspection Reports were used.Findings – The houses built under the HCGA (1988‐1996) from a previous study recorded an average of 2.29 defects per house. The 100‐house sample constructed under the DBCTA (1996 onwards) recorded 536 defects, equating to an average of 5.36 defects per house. This finding suggests that the quality of housing has dropped since the two Acts of Parliament were enacted. There also appears to be a significant increase in the number of consumers requesting inspections by industry professionals while construction is still in progress and before handover is achieved. This, coupled with the substantial increase in the number of defects .
Energy decay of some boundary coupled systems involving wave\ Euler-Bernoulli beam with one locally singular fractional Kelvin-Voigt damping

In this paper, we investigate the energy decay of hyperbolic systems of wave-wave, wave-Euler-Bernoulli beam and beam-beam types. The two equations are coupled through boundary connection with only one localized non-smooth fractional Kelvin-Voigt damping. First, we reformulate each system into an augmented model and using a general criteria of Arendt-Batty, we prove that our models are strongly stable. Next, by using frequency domain approach, combined with multiplier technique and some interpolation inequalities, we establish different types of polynomial energy decay rate which depends on the order of the fractional derivative and the type of the damped equation in the system.
A New Compact Broadband Radial Power Combiner

The N-way radial power combiner sums the power of N devices directly in one step without having to proceed through several combining stages. This results in high combining efficiencies and in a compact mechanical form. This dissertation presents a technique for the design of an N-way wideband microstrip radial power combiner which offers some advantages over axial power combiners. Thin microstrip lines in the combiner structure lead to low manufacturing costs and compact size and weight. A full analytical study is done and results are presented for an 8-way broadband microstrip radial power combiner operating from 2GHz to 17GHz. Also a full wave simulation using HFSS is done and the initial results are optimized for best performance. A couple of radial power combiners were built and measured: The achieved return loss is above 10dB and the insertion loss is below 1.5dB over the full bandwidth. These combiners were used to combine the outputs of 8 broadband amplifiers to produce a total output power of around 0.7W. For both passive and active stages, the obtained measurement results well validate the design and optimization processes.

Microcomputer-based Acceleration Sensor Device for Swimming Stroke Monitoring

The purpose of this study was to develop a microcomputer-based acceleration logger device for the swimming stroke monitoring. The authors measured the swimmer's tri-axial wrist acceleration and applied this device for the fatigue evaluation of the swimmers. The experimental protocol led the swimmers exhausted after the crawl stroke interval training. Every single stroke was determined by the impact acceleration peak, which appeared on the x and z-axis acceleration. The change of the underwater stroke phases was identified by the characteristics of the acceleration peaks. In their exhaustion, the y-axis acceleration, which was longitudinal forearm acceleration decreased at the beginning of the upsweep phase. At that time, the swimmer could not extend his elbow joint. Since the developed acceleration data logger could provide us the information about the underwater stroke phases and it would be a helpful tool in the swimming training.
Integral Sliding Mode Control of Sinusoidal Doubly Salient Electro-magnetic Motor Speed Regulation System Based on a Load Torque Observer

In order to enhance the speed regulation performance of sinusoidal doubly salient electro-magnetic motor (DSEM) drives, an integral sliding mode based on load torque sliding mode observer (LTSMO-ISM) speed controller is designed. This proposed LTSMO-ISM speed controller introduces the integral term of mechanical angular velocity error into the designed sliding mode surface to avoid the high frequency noise caused by the inherent differential action of the traditional sliding mode surface, which can enhance the dynamic and steady speed performance. A LTSMO is builded to observe motor load in real time, and the observation value is directly incorporated into the ISM controller, which can effectively suppress the speed fluctuation bringed by motor load step. The simulation results show that the proposed LTSMO-ISM speed controller is robust to load step and enhances the dynamic and steady performance of sinusoidal DSEM.
Neutrophil and Natural Killer Cell Interactions in Cancers: Dangerous Liaisons Instructing Immunosuppression and Angiogenesis

The tumor immune microenvironment (TIME) has largely been reported to cooperate on tumor onset and progression, as a consequence of the phenotype/functional plasticity and adaptation capabilities of tumor-infiltrating and tumor-associated immune cells. Immune cells within the tumor micro (tissue-local) and macro (peripheral blood) environment closely interact by cell-to-cell contact and/or via soluble factors, also generating a tumor-permissive soil. These dangerous liaisons have been investigated for pillars of tumor immunology, such as tumor associated macrophages and T cell subsets. Here, we reviewed and discussed the contribution of selected innate immunity effector cells, namely neutrophils and natural killer cells, as “soloists” or by their “dangerous liaisons”, in favoring tumor progression by dissecting the cellular and molecular mechanisms involved.
A novel common-mode sinusoidal inverter output filter with variable inductor

A long cable between a PWM inverter and a motor results in overvoltage at the motor terminals. A PWM voltage source inverter (VSI) generates common-mode voltage (CMV), which leads to shaft voltage and bearing current. A conventional inverter output filter can eliminate overvoltage when using a longer cable, but cannot achieve better filter effects under all kinds of conditions for its component values which are fixed and have no significant effect on CMV. A novel common-mode sinusoidal inverter output filter with variable inductor is proposed in this paper, which can automatically adjust cutoff frequency of the filter and achieve optimizing sinusoidal waveforms when operation conditions are varying. Simulation and experimental results identify the efficiency of the proposed filter.
What is the role of the next generation of cognitive robotics?

Social demand for robots to be our partners in daily life has been rapidly increasing. Cognitive robotics should play a major role in making robots our partners. To discuss the role of cognitive robotics, we organized the round table in December 2020. This review paper aimed at clarifying the role of cognitive robotics summarizing the discussion in the round table. The round table noted that the existence of uncertainty in the continuous control loop is a source of the need for cognitive robots and is the key factor that distinguishes cognitive robotics from the cognitive system in other fields. This paper summarized the discussion focusing on the creation of several cognitive functions without stopping even if the robots face novel uncertainty in daily life. We discussed information generalization, active sensing, prediction, and language communication as the necessary functions for future cognitive robots. One of the conclusions of the discussion is the importance of setting primitive but concrete targets for cognitive robotics research as cognitive robotics problems. We should continue to discuss the setting of these targets as a grand challenge for cognitive robotics. GRAPHICAL ABSTRACT
IN HIGH PERMEABILITY MATERIALS

Eddy currents flowing in thin skin depths are of great importance in some electrical machine parts, such as transformer tank walls and turbine generator rotors. The skin depth of the eddy currents is usually very small compared with the overall dimensions of the device, so that it is curl$ (gradTxn). n (3) uneconomic to model this type of problem by means of the usual 3D volume elements. It is shown here how surface elements can be used. Some experimental results are compared with simulations from the MEGA program (4) package.
Analysis of long-term anatomic results of radical mastoidectomy

A long-term, retrospective, non-controlled study was performed on the drainage results of mastoidectomy (both radical and modified radical) and the relevant statistical factors that could influence the anatomic outcome were defined. The present study took into consideration the same cohort of 200 patients we have communicated with before in our previous studies concerning the long-term functional results of mastoidectomy and long-term results of ossicular replacement with biovitroceramic prosthesis. The patients were clinically followed for the same period of 8.12 years. The drainage (anatomic) results, similar to previously published functional results, were defined by analytical function of the severity and the period of evolution of disease. The main goal was to define the situations and factors (presence of complications, type of disease, type of tympanic perforation or status of ossicular chain) that influenced the drainage results that could provide us with some type of anatomical prognosis. The follow-up started at the moment of complete epithelization for each cavity as time represents the main study comparison criteria. Drainage failure was assessed by the number of otorrhea episodes. It was concluded that practically and ideally, a maximum of 84% of the mastoid and petrous cells can be cleaned out. The results of 78% drainage success are congruent to this theory. The remaining 16% of cells may contain irreversible lesions.
Study on the Interface Effects Based on Two-Dimensional Green's Functions for the Fluid and Pyroelectric Two-Phase Plane under a Line Heat Source

Two-dimensional Green's functions for a line heat source applied in the fluid and pyroelectric two-phase plane are presented in this paper. By virtue of the two-dimensional general solutions which are expressed in harmonic functions, six newly introduced harmonic functions with undetermined constants are constructed. Then, all the pyroelectric components in the fluid and pyroelectric two-phase plane can be derived by substituting these harmonic functions into the corresponding general solutions. And the undetermined constants can be obtained by the interface compatibility conditions and the mechanical, electric, and thermal equilibrium conditions. Numerical results are given graphically by contours.

A Bibliometric Analysis and Benchmark of Machine Learning and AutoML in Crash Severity Prediction: The Case Study of Three Colombian Cities

Traffic accidents are of worldwide concern, as they are one of the leading causes of death globally. One policy designed to cope with them is the design and deployment of road safety systems. These aim to predict crashes based on historical records, provided by new Internet of Things (IoT) technologies, to enhance traffic flow management and promote safer roads. Increasing data availability has helped machine learning (ML) to address the prediction of crashes and their severity. The literature reports numerous contributions regarding survey papers, experimental comparisons of various techniques, and the design of new methods at the point where crash severity prediction (CSP) and ML converge. Despite such progress, and as far as we know, there are no comprehensive research articles that theoretically and practically approach the model selection problem (MSP) in CSP. Thus, this paper introduces a bibliometric analysis and experimental benchmark of ML and automated machine learning (AutoML) as a suitable approach to automatically address the MSP in CSP. Firstly, 2318 bibliographic references were consulted to identify relevant authors, trending topics, keywords evolution, and the most common ML methods used in related-case studies, which revealed an opportunity for the use AutoML in the transportation field. Then, we compared AutoML (AutoGluon, Auto-sklearn, TPOT) and ML (CatBoost, Decision Tree, Extra Trees, Gradient Boosting, Gaussian Naive Bayes, Light Gradient Boosting Machine, Random Forest) methods in three case studies using open data portals belonging to the cities of Medellín, Bogotá, and Bucaramanga in Colombia. Our experimentation reveals that AutoGluon and CatBoost are competitive and robust ML approaches to deal with various CSP problems. In addition, we concluded that general-purpose AutoML effectively supports the MSP in CSP without developing domain-focused AutoML methods for this supervised learning problem. Finally, based on the results obtained, we introduce challenges and research opportunities that the community should explore to enhance the contributions that ML and AutoML can bring to CSP and other transportation areas.
An Ultrafast Desaturation-Based Protection Circuit for GaN HEMTs

Gallium nitride high electron mobility transistors (GaN HEMTs) have an advantage in high switching speed and high frequency applications. However, the protection circuit for GaN HEMTs requires a fast response time due to the low robustness of short-circuit condition of GaN HEMTs. In addition, the high switching speed of GaN HEMTs generates severe noise, which causes a false-triggering for the protection circuit. This article is focused on analyzing the effect of switching noise on the protection circuit and proposes the protection circuit for GaN HEMTs with fast response speed and strong noise immunity. The protection circuit has been verified by SPICE simulation. The simulation results show that the protection delay of protection circuit is within 101 ns with strong noise immunity at normal operation.
A VIEW ON EXPERIENCE AND COMMUNICATION PERSPECTIVES IN LUNG CANCER PATIENTS IN CROATIA

Introduction: Well-balanced communication between healthcare professionals and oncology patients is the first step toward goals of caring for patients. Aims: In constant aim to improve patient outcomes, we aspired to uncover shortcomings in communication between healthcare professionals and patients suffering from lung cancer. An online survey of a non-probabilistic sample of cancer patients from twelve countries of Central and Eastern Europe designed and implemented by the Croatian Coalition of Associations in Healthcare. Methods: 472 lung cancer subjects were selected from the sample of results from 2,460 Croatian participants in the study from Oct. 2018. to Feb. 2019. Participants’ sociodemographic and clinical characteristics, experience and communication with healthcare professionals, key areas of inefficiency, psychological and social support were assessed. The analysis included descriptive statistics and chi square to assess demographic differences. Results: The study revealed four main results: (i) only a minority of the participants were satisfied with the communication process, (ii) majority were not told that they could bring family member during delivering bad news, (iii) there was a clear unmet need to have a discussion on the impact of cancer on day to day activities (iv) participants’ preferences indicate that the greatest improvement would be to perform all services at one place. Conclusions: This study revealed that one of the leading problems in oncology care according to patients is the lack of education and effective communication. Based on the obtained data, we conclude that there is a large space for improvement in patient experience and communication.
