Employee's Attitude toward Electronic Administration Adoption: A Case Study of Al-Mustansiriyah University

The advancement of the information and communications technology has helped almost all governments across the world as they have exploited these technologies for delivering services to their citizens. However, this phenomenon may face several challenges and barriers that lead to the failure in its adoption, use, or continuous USAge. In the Arab countries, the rate of failure in the use of electronic services is high in the public sector. Therefore, previous studies have concentrated on this critical issue and highlighted on the citizens' perspective andignored the perspective of employees in the government organizations.In addition, very few previous studies dealt with the quality of the services based on the employees'viewpoint. Thus, based on the arguments that have been stated earlier, this preliminary study strives to identify the factors that may affect the electronic administrative adoption according to the employees' perspective. With regard to the data collection, the quantitative method, self-administered questionnaires will be distributed among the staff of the Al-Mustansiriyah University, Iraq.With regard to data analysis, a partial least squares structural equation modelling will be used as a technique to analyse the collected data from a key respondent (Employee). In fact, this research strivesto enrich the literature by adding more information about the factors that may hinder theadoption of modern technologies in general and electronic administration in particular. With regard to the Al-Mustansiriyah University, the present study is considered as the first study conducted in this area; therefore the outputs will assist the government to remedy these obstacles before beginning any project in the public sector including the use of ICT instead of the conventional manner.The result of the analysis showed that system quality, service quality, trust of organization, and usefulness were found as significant factors that affect the employees' adoption of e-administration services in University

Only Elongated Chordae Tendineae is Important Entity of MVP Syndrome

Back ground Mitral valve prolapse [MVP ]is the most common valvluar abnormities . Echocardiographically MVP classified to two types, classical MVP ,more commonly occur in male after age of 40 years and usually associated with complications and non-classical MVP, usually in young female and usually benign , but commonly associated with autonomic dysfunction [MVP syndrome ]. Method 2676 patients (1985 female Vs. 691 male), their age between 12—81 year, were referred for ECHO study because of clinical suspicion of MVP, 2-D Color-Doppler ECHO study in left parasternal long axis view was done for them in addition to 12-lead ECG, patients were triage as group 1. classical MVP [define as more than 2mm displacement of mitral valve leaflet in to left atrium in addition to leaflet thickness 5mm or more] 2. Non-classical MVP [ 2 mm or more displacement with leaflet thickness less than 5mm.] 3. This group show no displacement with normal thickness of leaflet but show only elongated and fluttering chordae tendinae labeled as only elongated chordae group and group 4 which show completely normal ECHO [ labeled as non-prolapsing MVP syndrome],this group was excluded from the study. Result 283 patients [31.58%] have classical MVP [122 female vs. 151 male], 315 patients [35.1%] show non-classical MVP [236 female vs.79 male] while 298 patients [33.25%] show only elongated chordae [216 female vs. 82 male]. While 1780 patients [66.51%] have normal ECHO [ non prolapsing MVP syndrome. Mitral regurgitation [MR] occure in 203 patients of classical MVP [71.73%] (36 female vs. 167 male) while 132 patients (42%) [89 female vs.43 male] of non-classical MVP have MR and only 6 patients (2%) [5 female vs. 1 male] with only elongated chordae show MR. Conclusion Most patients with clinical suspicion of MVP have no evidence of prolapsed by ECHO study, those with ECHO finding may show either classical or non—classical MVP. Significant number of patients show only elongated chordae tendinae without prolapsed. So elonongated chordate can consider as important cause of MVP syndrome

A PSO-Optimized Reciprocal Velocity Obstacles Algorithm for Navigation of Multiple Mobile Robots

In this paper, a new optimization method for the Reciprocal Velocity Obstacles (RVO) is proposed. It uses the well-known Particle Swarm Optimization (PSO) for navigation control of multiple mobile robots with kinematic constraints. The RVO is used for collision avoidance between the robots, while PSO is used to choose the best path for the robot maneuver to avoid colliding with other robots and to get to its goal faster. This method was applied on 24 mobile robots facing each other. Simulation results have shown that this method outperforms the ordinary RVO when the path is heuristically chosen

Modified (2PVCP) for Better Transaction Processing in Secure Cloud

Entities in distributed transactional database that published over cloud servers, collaborate to make evidence of ownership, this evidence are warranted by groups of legalized credential. This evidence and credential may be estimated and gathered over extended time period under the risk of having the essential ownership policies or the user that use this credential may use it out of these policies, for that becomes policy based ownership systems to make unsafe judgment that threaten sensitive resources. In this paper, the highlight is for the criticalness of this risk or problem, and then we declare the concept of trusted transaction when dealing with evidence of ownership. Accordingly the paper suggests increasingly stringent level of policy consistency constraints, and provides different implementation approximation to warranty the trustworthiness of transaction executing on cloud server. So we propose a Tow Phase Validation Commit Protocol as solution that modifies Tow Phase Validation Commit Protocols. At the last, we analyzed the different implementations by using both analytical estimation of the overheads and emulation to lead the judgment maker to decide which scheme to use. We built a prototype application that demonstrates the proof of concept. The empirical results revealed that the mechanisms pertaining to distributed transactions can be used in the real world cloud applications. DOI: 10.17762/ijritcc2321-8169.150711

Experimental and Numerical Investigations of Composite Concrete–Steel Plate Shear Walls Subjected to Axial Load

This research is presented experimental and numerical investigations of composite concrete-steel plate shear walls under axial loads to predicate the effect of both concrete compressive strength and aspect ratio of the wall on the axial capacity, lateral displacement and axial shortening of the walls. The experimental program includes casting and testing two groups of walls with various aspect ratios. The first group with aspect ratio H/L=1.667 and the second group with aspect ratio H/L=2. Each group consists of three composite concrete -steel plate wall with three targets of cube compressive strength of values 39, 54.75 and 63.3 MPa. The tests result obtained that the increase in concrete compressive strength results in increasing the ultimate axial load capacity of the wall. Thus, the failure load, the corresponding lateral displacement and the axial shortening increased by increasing the compressive strength and the rate of increase  in failure load of the tested walls  was about (34.5% , 23.1%) as compressive strength increased from 39 to 63.3 MPa for case of composite wall  with aspect ratio H/L=1.667 and  H/L=2, respectively. The effect of increasing aspect ratio on the axial load capacity, lateral displacement and axial shortening of the walls was also studied in this study. Compared the main performance characteristic of the testing walls, it can be indicated that the walls with aspect ratio equal to (2) failed under lower axial loads as compared with walls with aspect ratio equal to 1.667 ratios by about (5.8, 12, 15.6 %) at compressive strength (39, 54.75, 63.3 MPa), respectively and experienced large flexural deformations. The mode of failure of all walls was characterized by buckling of steel plates as well as cracking and crushing of concrete in the most compressive zone. Nonlinear three-dimensional finite element analysis is also used to evaluate the performance of the composite wall, by using ABAQUS computer Program (version 6.13). Finite element results were compared with experimental results. The comparison shows good accuracy

Color Image Encryption Using LFSR, DNA, and 3D Chaotic Maps

One of the most important challenges facing researchers is to find new methods to protect data sent over the Internet and prevent unauthorized access to it. In this paper, we present a new method for encrypting image data divided into two stages. The first stage requires redistributing the positions of the pixels by using a key of random numbers generated by linear feedback shift registers and then encrypting the data using deoxyribonucleic acid rules. The data generated in the previous stage is encrypted again using chaotic maps to increase the level of security in the second stage. Several statistical tests were implemented to verify the efficiency of the proposed method and compare the results with the work of other researchers. The results of the tests proved a reasonable safety rate compared to other techniques

Flexural Behavior of Composite GFRP Pultruded I-Section Beams under Static and Impact Loading

In this study, the effect of glass fiber reinforced polymer (GFRP) section and compressive strength of concrete in composite beams under static and low velocity impact loads was examined. Modeling was performed and the obtained results were compared with the test results and their compatibility was evaluated.‎ Experimental tests of four composite beams were carried out, where two of them are control specimen with 20 MPa compressive strength of concrete deck slab and 50 MPa for other. Bending characteristics were affected by the strength of concrete under impact loading case, as it increased maximum impact force and damping time at a ratio of 59% and reduced the damping ratio by 47% compared to the reference hybrid beam. Under static loading, there was an increase in all the parameters, including the maximum load, ductility, and stiffness. Mid-span deflection was reduced by 25% under static and impact loads. A finite element analysis was performed by using the ABAQUS software. The midspan deflection value was greater than the experimental values by 6% and 3% for impact and static loads, respectively, and all other results showed a high rate of agreement with the obtained test results. The agreement between the numerical and experimental results indicates that the developed numerical model is capable of analyzing the impact and static behavior of such hybrid GFRP-concrete system. Doi: 10.28991/cej-2020-03091608 Full Text: PD

A Practical Evaluation of English for Iraq: Pupil's Book (4th Primary): Designing and Planning

In 2016, the Directorate of Curriculum and Methodology in the Ministry of Education in Iraq altered the old English textbook allocated for the forth-primary class with a new textbook called English for Iraq: Pupil's Book. After implementing this new textbook, the teachers, who are teaching this material, addressed a set of criticisms stating that the design and structure of this book does not fit the comprehensive levels of the pupils. As teachers emphasized that they encountered difficulties in teaching this material because they should have joined an intensive session for how to teach the new textbook before teaching it in the schools. Investigating the opinions of the teachers about the contents of the book, they believe that the grammatical topics apportioned for the forth grade are beyond the pupils' grasp where the writers set down rules of comparative and superlative degrees which pupils cannot perceive and should be given for the high school classes. Consequently, the teachers are obliged to choose simple and recognized topics and leave the topics – especially grammatical ones which confuse their minds if they are given to them. Thus, the initiative evaluation shows that the textbook contains difficult modules as it lacks practicing the four skills of the English language, in addition to the insufficiency of using the illustrative aids in the classroom.Keywords:  Evaluation, Designing, Structure, Weaknesses, Planning.
