Marzouk, Mohamed,Attia, Tarek,El-Bendary, Nasr Eldin Korea Institute of Construction Engineering and Ma 2012 Journal of construction engineering and project ma Vol.2 No.1

Maturity models allow organizations to assess and compare their own practices against best practices or those employed by competitors, with the intention to map out a structured path to improvement. This research explores the aspects of the Maturity Models that are relevant to distinguish them from one to another. The different Project Management maturity models for define maturity differently and measure different things to determine maturity. Because of this, organizations should give careful consideration to select appropriate maturity model. The main reason behind this research lies on the modification to the existing Organizational Project Management Maturity Model (OPM3) by adding four knowledge areas, dedicated to construction industry as best practices. These are Safety, Environment, Financial and Claim Management. This Model contains (Yes/No) questions; all of these questions must be answered before the user reviews the results that describe the overall maturity and areas of strength and weakness of an organization. The research presents the implementation of the proposed Model Construction Enterprises Maturity Model (CEM2). All the components of the developed Model have been implemented in Microsoft Access. CEM2 helps Construction Enterprises to assess their Maturity Level and know Areas of Weaknesses for future improvement. The easy to use Yes/No user interfaces help enterprises' employees to assess the maturity level of their enterprises. The Model maintains users' responses in its database; as such, many employees from different enterprise divisions can be involved during assessment phase in several sessions.

Marzouk, Tyseer,Nabil, Hanan,Senna, Mohammed Korean Society of Women Health Nursing 2015 여성건강간호학회지 Vol.21 No.3

Purpose: This study aimed to evaluate the impact of a lifestyle modification program on menstrual irregularity among overweight and obese women with polycystic ovarian syndrome. Methods: A quasi experimental research design was used to conduct this study on 82 women with polycystic ovarian syndrome at the Gynecology and Obesity clinics of Mansoura University Hospital, Egypt. Two groups were included; the study group received a lifestyle modification program for 48 weeks, while the control group was not subjected to this program. Data collection was done for the following variables, a structured interview questionnaire was used to assess the women's general characteristics, menstrual patterns, and 24-hour dietary recall and the researcher took anthropometric measurements and assessed hirsutism by the Ferriman-Gallwey scale. Results: After one year of lifestyle modification, the number of menstrual cycles significantly increased from $2.7{\pm}1.6$ to $6.9{\pm}1.5$ (t=12.26, p<.001) in the study group compared to insignificant minor changes among the control group (t=0.69, p=.488). Additionally, 58.5% were menstruating regularly compared to none in the control group (${\chi}^2=33.93$, p<.001). Conclusion: Participating in a lifestyle modification program was effective in reducing menstrual cycle's irregularity among overweight and obese women with PCOS. Thus, it is recommended to motivate the nurses in counseling the PCOS women on lifestyle modifications.

Quantifying Weather Impact on Formwork Shuttering and Removal Operation using System Dynamics

Mohamed Marzouk,Ahmed Hamdy 대한토목학회 2013 KSCE JOURNAL OF CIVIL ENGINEERING Vol.17 No.4

Weather condition is a significant factor that influences the activities of construction projects. This paper presents a framework that forecasts the losses on productivity due to the impact of weather conditions. The framework consists of three components; historical records database, analytical fuzzy model, and system dynamic model. The productivity of formwork shuttering and removal is directly impacted by two weather aspects; level of rain and temperature degree. The loss in productivity is modeled via analytical fuzzy model and system dynamic model. The proposed framework incorporates historical weather records, expert experiences, and fuzzy-set techniques in productivity losses forecasting. It provides more realistic forecast for productivity losses considering the impact of rain and temperature rises. Construction contractors benefit from the framework by assigning appropriate crew size for formwork shuttering and removal to meet project requirements with respect to total duration of project execution. A numerical example is presented to demonstrate the use of the proposed framework.

Mohamed Marzouk,Mohamed Hisham 대한토목학회 2014 KSCE JOURNAL OF CIVIL ENGINEERING Vol.18 No.5

Building Information Modeling (BIM) has widely become an effective tool in engineering and construction fields. It could be usedin: generating shop drawings; detecting clashes; estimating quantities; and controlling documents. Applying BIM technology onbridges is named Bridge Information Modeling (BrIM). Bridge Information Modeling (BrIM) is an intelligent representation ofbridges since it contains all information needed about bridges through their whole lifecycle. This paper presents the use of BuildingInformation Modeling in cost and time management of infrastructure bridges. BIM-based cost estimation application is presentedwhich is capable to carry out approximate cost estimate; and detailed cost estimate. The application is designed in a flexible mannerto be used with default values, or user defined values. Different performance measurement indexes are used in order to control thecost and schedule during execution phase of construction projects. This application integrates BIM with Earned Value (EV) conceptto determine the project status at specific reporting date. A case study is presented to demonstrate the use of the developed modules.

Video laryngoscope versus USB borescope-aided endotracheal intubation in adults with anticipated difficult airway: a prospective randomized controlled study

Elshazly Mohamed,Medhat Mark,Marzouk Sahar,Samir Enas M. 대한마취통증의학회 2022 Korean Journal of Anesthesiology Vol.75 No.4

Background: Video laryngoscopes are approved equipment for difficult airway intubations. The borescope, which was introduced during the coronavirus disease 2019 (COVID-19) era, is placed over a direct laryngoscope blade to provide an economical video laryngoscope. In the current study, we investigated the use of an endotracheal tube mounted over a USB borescope versus a video laryngoscope in patients with suspected difficult airways.Methods: After obtaining informed consent, 120 adult patients with suspected difficult airways undergoing elective surgery were included in this study. Patients were randomized into the USB borescope and video laryngoscope groups. The primary outcome was time to successful intubation. The secondary outcomes included hemodynamic changes, anesthetist’s satisfaction, and the incidence of complications.Results: Intubation time was comparable between the two groups (video laryngoscope: 30.63 s and borescope: 28.35 s; P = 0.166). However, the view was clearer (P = 0.026) and the incidence of fogging was lower (P = 0.015) with the video laryngoscope compared to the borescope. Conversely, anesthetist’s satisfaction frequency was higher with the borescope than with the video laryngoscope (P < 0.001).Conclusions: The video laryngoscope provided a better view and less fogging with an intubation time that was comparable to that of the borescope; however, the higher cost of the video laryngoscope limits its availability. Therefore, the borescope is a low-cost, readily available device that can be used for intubating patients with potentially difficult airways.

Abdelmeguid Yasmine,Mowafy Ehsan Wafa,Marzouk Iman,Franco Elisa De,ElSayed Shaymaa 대한소아내분비학회 2022 Annals of Pediatirc Endocrinology & Metabolism Vol.27 No.3

Purpose: In patients diagnosed with diabetes mellitus (DM) before the age of 12 months, there is an increasing recognition of diabetes caused by single-gene mutations, also known as monogenic diabetes of infancy or neonatal DM (NDM). This study aimed to classify patients at Alexandria University Children’s Hospital (AUCH) diagnosed with infantile-onset DM into type 1 DM (T1DM) or NDM and to detect differences in molecular characteristics of NDM patients at our center in comparison to other countries. Methods: This retrospective/prospective observational study was conducted on 39 patients diagnosed with infantile-onset DM (age of onset ≤1 year) at AUCH from January 2003 to November 2020. The patients were divided into 2 groups according to age at the onset of DM: ≤6 months and >6–12 months. Molecular testing was done in patients diagnosed with DM at ≤6 months and those with negative autoantibodies. Results: Twelve patients were diagnosed with DM at age ≤6 months and 27 patients were diagnosed between 6–12 months. Seventeen patients (43.6%) had T1DM, whereas 9 patients (23.1%) had genetically confirmed NDM, including 3 harboring novel mutations. The most common genetic causes of NDM were EIF2AK3 mutations (n=3), followed by KCNJ11 (n=2) and ABCC8 (n=2). Other mutations included SLC19A2 (n=1) and INS (n=1). Three patients with potassium ATP channel mutations were transferred from insulin to sulfonylurea treatment. Conclusion: It is essential to identify patients with NDM clinically and confirm the diagnosis by molecular testing to distinguish them from T1DM as it helps in refining their management, predicting prognosis, and guiding genetic counseling.
