Development and Implementation of Sustainability IoT Based Curriculum

Sustainable development has three main pillars, economic, social, and environmental. In the strive for a sustainable world, environmental and social issues must be addressed as they affect the world economy. With the past industrial revolutions and their negative effects on our world, it is becoming essential to involve students in sustainability as engineering and technology are important elements into fixing the past negative effects on our planet. Consequently, educating engineering students on sustainable development is wide spreading in the past few years and is actually taking place worldwide in many modern faculties and universities. Aside from the United Nations mandates, it is those engineers who are to make the efforts in their respective fields to create ways to improve the sustainable world around us. There are many methods to go about teaching such a subject, some are direct and some uses indirect methods. Building upon the experience of others and the wide spectra of methods, a new curriculum is designed, based on innovations in technologies, to cover sustainability along with environmental and social implications. The curriculum relies on a mixture of learning techniques especially suitable for a developing and growing educational environment where the subject matter experts are not abundantly available. The method used in the design and implementation allows flexible usage and integration of the course by educational institutions and new universities. The results of applying the course content on a sample of 50 student is collected and analysed. The tabulated data and graphs show the strong points of the course materials as well as the areas of improvements.

Immersive Energy Network Operation System for Renewable Resources

I Introduction As new energy sources are beginning to spread in developing countries, there is a need to track and monitor them. Moreover, there is a need to control the operation of these renewable energy resources. A monitoring and control system can range from simple on-site computerized maintenance terminal to a full Network Operation Center (NOC) on the scale of city or even the whole country. The NOC will be connected to energy source controllers via some network connection. The controllers will then connect to the sensors in the power system and convert the digital data to sensor signals and vice-versa. A data network is used to connect the on-site controllers with the control centers. The communication can be based on wired or wireless media. Examples include leased telephone lines, WAN circuits, licensed and unlicensed radio, cellular, microwave, or even satellite for remote areas that have no network coverage. An immersive virtual environment, represented by a practical virtual world implementation, is incorporated. Through the virtual world, it is possible to add visualization combined with other virtual world abilities such as avatar collaborative interaction II NOC Background This section provides the needed background on NOC and their main functionalities.NOC is a centralized location where IT technicians can directly support the efforts of remote monitoring and management of network elements.The NOC staff is responsible for monitoringthe network element and make decisions and adjustments to ensure optimal network performanc

Experimental Evaluation of Internet of Things in the Educational Environment

In the trials of utilization of technology for the society, efforts have shown benefits of the ICT use in facilitating education from different perspectives based on different waves of technological change. The recent development in technologies has also resulted in change of user behavior and usage patterns towards different areas of life, and consequently in the area of education. A new wave of change has started and is expecting to proliferate with stronger connectivity and interoperability of various devices, named as the Internet of Things (IoT). The internet of things is expected to give strong impacts on different areas of life including healthcare, transportation, smart homes, smart campus, and more. Consequently, there are inherent benefits to the education environment that are not yet well established in literature. The paper studies the potential benefit and impact of the IoT evolution concept in both the physical and the virtual learning environment and suggests a paradigm with use case scenarios. The results of an experimental evaluation on the aspects of applying IoT technology in education are presented and discussed in order to verify the set of related hypotheses

Multimedia on Local Area Networks

In this paper we address the issues related to the delivery of multimedia streams on local area networks. Multimedia integrates voice and video along with text and images into existing systems. Local area networks were designed to handle regular data traffic which are bursty in nature and for which variable delay is acceptable. Multimedia traffic, on the other hand, requires constant delay in addition to fast (or real time) delivery. Multimedia traffic also requires large amount of bandwidth compared to regular traffic. Since local area networks are widely in use, their modification to integrate multimedia streams is very important. In our work we consider some possible solutions to the problems associated with multimedia on local area networks as well as studying the performance aspects of these solutions. Key words: Multimedia, local area networks, synchronization, priority, switching hubs. 1 Introduction Multimedia is a media that integrates the transmission of voice and video alo..

An Energy Efficient Wearable Smart IoT System to Predict Cardiac Arrest

Recently, many people have become more concerned about having a sudden cardiac arrest. With the increase in popularity of smart wearable devices, an opportunity to provide an Internet of Things (IoT) solution has become more available. Unfortunately, out of hospital survival rates are low for people suffering from sudden cardiac arrests. The objective of this research is to present a multisensory system using a smart IoT system that can collect Body Area Sensor (BAS) data to provide early warning of an impending cardiac arrest. The goal is to design and develop an integrated smart IoT system with a low power communication module to discreetly collect heart rates and body temperatures using a smartphone without it impeding on everyday life. This research introduces the use of signal processing and machine-learning techniques for sensor data analytics to identify predict and/or sudden cardiac arrests with a high accuracy

How i do it: A practical database management system to assist clinical research teams with data collection, organization, and reporting

With the growing amount of research projects in the field of interventional radiology, storing and organizing the patients' data and information effectively is becoming more difficult. Existing hospital electronic medical record and archiving systems store patient information in the form of reports which put the physicians and researchers in a situation where they have to use time-consuming manual search through reports for suitable patients for different clinical researches. Spreadsheet programs such as Microsoft Excel® (Microsoft, Washington, USA) are often used as a data storage, which has limitations in both organization and the quality of the data. Higher risk of incorrect data entry and introducing duplicates are associated with data input and analysis without a database system. Furthermore, selection, as well as calculation of data, is time-consuming. This article aims to provide interventionists with an efficient data collection tool optimized for interventional oncology clinical research. The implementation of the current database and interface allows a much faster and more detailed retrospective analysis of patient cohorts. The database management system with an interface is a very time-efficient and robust tool that provides a significant edge over the manual retrieval of patient records by filtering data and assisting statistical analysis in a study-relevant fashion

Global Incidence and Risk Factors Associated With Postoperative Urinary Retention Following Elective Inguinal Hernia Repair

Importance Postoperative urinary retention (POUR) is a well-recognized complication of inguinal hernia repair (IHR). A variable incidence of POUR has previously been reported in this context, and contradictory evidence surrounds potential risk factors.Objective To ascertain the incidence of, explore risk factors for, and determine the health service outcomes of POUR following elective IHR.Design, Setting, and Participants The Retention of Urine After Inguinal Hernia Elective Repair (RETAINER I) study, an international, prospective cohort study, recruited participants between March 1 and October 31, 2021. This study was conducted across 209 centers in 32 countries in a consecutive sample of adult patients undergoing elective IHR.Exposure Open or minimally invasive IHR by any surgical technique, under local, neuraxial regional, or general anesthesia.Main Outcomes and Measures The primary outcome was the incidence of POUR following elective IHR. Secondary outcomes were perioperative risk factors, management, clinical consequences, and health service outcomes of POUR. A preoperative International Prostate Symptom Score was measured in male patients.Results In total, 4151 patients (3882 male and 269 female; median [IQR] age, 56 [43-68] years) were studied. Inguinal hernia repair was commenced via an open surgical approach in 82.2% of patients (n = 3414) and minimally invasive surgery in 17.8% (n = 737). The primary form of anesthesia was general in 40.9% of patients (n = 1696), neuraxial regional in 45.8% (n = 1902), and local in 10.7% (n = 446). Postoperative urinary retention occurred in 5.8% of male patients (n = 224), 2.97% of female patients (n = 8), and 9.5% (119 of 1252) of male patients aged 65 years or older. Risk factors for POUR after adjusted analyses included increasing age, anticholinergic medication, history of urinary retention, constipation, out-of-hours surgery, involvement of urinary bladder within the hernia, temporary intraoperative urethral catheterization, and increasing operative duration. Postoperative urinary retention was the primary reason for 27.8% of unplanned day-case surgery admissions (n = 74) and 51.8% of 30-day readmissions (n = 72).Conclusions The findings of this cohort study suggest that 1 in 17 male patients, 1 in 11 male patients aged 65 years or older, and 1 in 34 female patients may develop POUR following IHR. These findings could inform preoperative patient counseling. In addition, awareness of modifiable risk factors may help to identify patients at increased risk of POUR who may benefit from perioperative risk mitigation strategies

Pancreatic surgery outcomes: multicentre prospective snapshot study in 67 countries

Background: Pancreatic surgery remains associated with high morbidity rates. Although postoperative mortality appears to have improved with specialization, the outcomes reported in the literature reflect the activity of highly specialized centres. The aim of this study was to evaluate the outcomes following pancreatic surgery worldwide.Methods: This was an international, prospective, multicentre, cross-sectional snapshot study of consecutive patients undergoing pancreatic operations worldwide in a 3-month interval in 2021. The primary outcome was postoperative mortality within 90 days of surgery. Multivariable logistic regression was used to explore relationships with Human Development Index (HDI) and other parameters.Results: A total of 4223 patients from 67 countries were analysed. A complication of any severity was detected in 68.7 percent of patients (2901 of 4223). Major complication rates (Clavien-Dindo grade at least IIIa) were 24, 18, and 27 percent, and mortality rates were 10, 5, and 5 per cent in low-to-middle-, high-, and very high-HDI countries respectively. The 90-day postoperative mortality rate was 5.4 per cent (229 of 4223) overall, but was significantly higher in the low-to-middle-HDI group (adjusted OR 2.88, 95 per cent c.i. 1.80 to 4.48). The overall failure-to-rescue rate was 21 percent; however, it was 41 per cent in low-to-middle-compared with 19 per cent in very high-HDI countries.Conclusion: Excess mortality in low-to-middle-HDI countries could be attributable to failure to rescue of patients from severe complications. The authors call for a collaborative response from international and regional associations of pancreatic surgeons to address management related to death from postoperative complications to tackle the global disparities in the outcomes of pancreatic surgery (NCT04652271; ISRCTN95140761)
