Smart construction companies using internet of things technologies

The digital world is enriched due to the increase in the number of things which are rapidly connecting to the Internet. The Internet of Things (IoT) facilitates and improves the work efficiency and human life in various fields. IoT was adopted extensively to male buildings more effective and extra smart. For example, buildings are consuming a considerable energy amount. In buildings, there is a critical requirement for energy efficiency, whereas one of the smart building’s aims is monitoring, reducing and managing the energy consumption of buildings without compromising the operational efficiency and the comfort of occupants. The systems of Heating, Ventilation and Air Conditioning (HVAC) are contributing to considerable consumption of energy in buildings. Also, plug loads and lighting are consuming a lot energy. Thus, smart buildings have the ability of using many IoT sensor types in HVAC along with other mechanical systems making such more adaptive and intelligent. The embedded sensors as well as their related controllers which are mounted in smart buildings are generating a huge amount of data (big data), such data might be subjected to extraction, filtration ana analyzation and utilized for the analytics of smart buildings. For example, the big data analytics might be utilized for analyzing and improving the energy efficiency in addition to the residents’ overall user experience in building. It has been verified that there is an increased focus on smart buildings and big data analytics and management. Yet, there is a requirement for identifying the problems and solutions for overcoming them in such field. With the use of a design research method and model driven architecture, this study aims to develop such system.The major aim of this work is introducing a technique with increased possibility for moving Intelligent Buildings (IBs) towards next-generation model. It depends on IoT adapted to IB for integrating smart re-configurable subsystems and components of IB into Enterprise Network Integrated Building Systems (ENIBSs), also, if possible, into ENIBS’ global networks. The study is presented in the following way. Section 2 is providing an overview of IoT, it is indicating that IoT is relatively new and no associated contribution on using the IoT on IBs or, on the ENIBSs, were indicated in such regard. Section3 is presenting the methodological model that has been used to design a generic model for the IoT with the applicability in the IBs as well as generic architectures for re-configurable smart plug-and-play control systems for quick configuration and integration regarding smart components of the IB. Section 4 provides the theory’ experimental test. The study ends up with the conclusions and some suggestions for the future work

Biochemical Changes in Relation to Blood Hemoglobin of Anemic Heamodialysis Patients Treated with Mircera at AL- Hussein Dialysis Center in Thi-Qar Province / Iraq

Background : Anemia is a reduction in the number of RBC count and resulting mainly from reduced erythropoietin production due to the damage or loss of kidneys function in chronic renal failure ( Renal anemia) and is a common complications in hemodialysis patients. The objectives: This study design to evaluate the changes in some biochemical parameters and the relation with blood hemoglobin, for post-heamodialysis patients treated with stable dosage of Mircera ( Methoxy polyethylene glycol - epoetin beta 75 µg/0.3 ml, Germany). Patients and method: Blood of 95 patients were collected from AL- hussien dialysis center in Thi-Qar province / Iraq within three months period, number of dialysis session was two time per week for two hours each session. After heamodialysis session, patients treated with stable dosage of Mircera (0.6 µg) for every kilogram of body weight once every 2 weeks . The data and biochemical finding of their blood sample collected after heamodialysis session. Results: A ninety fife HD patients included 65 (68.4%) were male and 30 (31.6%) were female, aged between 19 to 65 years, their total body weight was 59.34 ± 1.33 Kg and their blood analysis are normal glycemia 5.4 ± 0.51 mmol/l , normal natraemia 137± 0.77 mmol/l, but hyperkalamia (6.1 ± 0.9 mmol/l) , hyperuraemia (21.78± 4.13 mg/dl) , hypercreatinaemia (2.2 ± 0.98 mg/dl) , and the mean HB value was (8.38 ± 1.18 g/dl). The results of response to Mircera show only one patient (1.05 %) had mean HB values (12.0 g/dL) within the target range recommended by KDOQI guideline. Seventy patients (73.69 %) had mean HB value between 8.0 to 10.9 g/dL, twenty four patients (25.26 %) had mean HB values between 5 - 7.9 g/dL and there are no one (0.0 %) had exceed the recommended range (>12 g/dL). Anemia degree positively related with hyperuraemia and hypercreatinaemia . Conclusions: There are Hyporesponsiveness to mircera (75µg/0.3 ml) therapy in hemodialysis patients associated with reducing dialysis efficiency slightly for potassium, urea and creatinine and that positively related with anemia degree .

The attitude of undergraduates towards E-learning considering educational and technical challenges and requirements in Kuwaiti Applied Colleges

Digital learning has become one of the constituent elements of higher education in many countries. E-learning platforms provides remarkable opportunities to creatively overcome many problems of traditional learning approaches. Nevertheless, E-learning is not flawless, where there are many educational and technical difficulties of implementing online learning in higher education, especially when higher education stands on applied learning. The current study aims to explore undergraduates’ attitudes towards E-learning in applied colleges. It also seeks to expose the most central educational and technical challenges of e-learning. Moreover, it drives to define the educational and technical requirements for ensuring quality e-learning. the research sample consisted of 1650 undergraduates and 37 interviewees who are drawn from five applied colleges in Kuwait (the College of Basic Education, the College of Technological Studies, the College of Business Studies, the College of Health Science, and the College of Nursing). The research design is based on mixed methods (questionnaire and focus groups). The findings revealed that students held neutral attitudes towards e-learning, while the educational and technical challenges are high concerns. Educational challenges and requirements highlighted several themes including instructional support, progress valuation, self-study skills, attention span, interactivity, and class size. Meanwhile, the technical challenges include poor internet connectivity, IT support, LMS interface, training courses. Then, the findings are discussed to draw recommendations and implicationsPeer Reviewe
