Exploring Information Centers\u27 Roles in the Use of Data Warehouses

Data warehouses are user-driven; therefore, a very important aspect of data warehousing research would be studying the interaction between end-users and data warehouses. As user satisfaction is commonly acknowledged as the most useful measurement of system success, we intend to identify in this article the underlying factors of end-user satisfaction with data warehouses, especially the roles of information centers in the use of data warehouses. The study demonstrates that most of the items in classic end-user satisfaction measure are still valid in the data warehouse environment and that end-user satisfaction with data warehouses heavily depends on the roles and performance of Information Centers in organizations

Identification of Test Cases from Business Requirements of Software Systems,

Many organizations are struggling between the fast delivery of new software and quality assurance. Software testing play a key part in the quality assurance of software systems. Formal testing techniques increase software quality and, at the same time, reduce software development cycle time. This article presents a methodology for the identification and definition of black box test cases based on the functional requirements of a software system. The methodology is applied during the initial phases of software development. The method involves analyzing system requirements and constructing a functional description graph to organize these requirements

Management Information Systems Research: What\u27s There in a Methodology?

Management information systems (MIS) is both a young and unique field , constantly experiencing rapid change and turmoil. Consequently, MIS research faces dual changes of rigor and relevance. Many research methodologies exist that provide various combinations of rigor and relevance. The MIS researcher selects a methodology based on several factors including rigor, relevance, subject area, and personal preferences. In this article, we examine thirteen different methodologies as used by seven leading MIS journals during a recent five-year period. The results of this extensive analysis yielded some interesting results. Survey methodology consistently ranks at the top; while frameworks and conceptual models, lab experiments, and case studies also found significant use among the MIS community. Several trends were observed, one of them being a greater use of the case study method and other qualitative technologies over the years. Clear patterns also emerged based on the journal itself and the subject areas. At a macro level, this information should help authors in the choice of appropriate methodologies to use in specific subject areas and in targeting manuscripts to appropriate journals. It would also be helpful to journal editors in assessing the type of research and methods being used across journals and subjects, and whether they need to make any changes in the emphases of their own journals

The Design and Implementation of Integrated E-Cart on E-Hyper Market

The idea in this paper is to design and build an E-Business Market that is very huge; the purpose is to enable customers to buy through the World Wide Web by applying the Browser-server architecture in Electronic Commerce. With the possibility of selling any type of goods, whether it2019;s digital or physical, you would need to increase the proportion of sales to ensure customer convenience. The hypermarket is trying as much as possible to make the process of purchasing goods very simple, therefore it is building and configuring a comprehensive electronic commercial site on the Internet. The new hypermarket provides novel services. It includes a number of commercial sites. The management of products that are offered by each site are done through the site owner. The site owner will manage the system and modify the products of his site through a set of tools provided by the main site. A new way is used to display the various products type which makes the navigation in the site and comparing its products with other related sites very easy. The E-Hyper Market website provides a flexible method of payment that allows the customer to select a payment plan that suits him. Also, unique search schema is offered. The searching process of the products according to certain conditions can be accomplished in a detailed search. This properties based search depends on determining the values and the ranges of the characteristics of the product, which provides accurate results. We have used ASP.NET as a programming language to implement this project and the database program that is used to store the products data is MY SQL. Given the extra services mentioned above, our site will be more flexible and easier to use compared with other similar sites

VISUALIZATION-BASED DECISION SUPPORT FOR OPTIMIZING SITE SELECTION:QUARRIES IN LEBANON; WHERE TO?

Traditionally the term visualization has been used to describe the process of graphically conveying or presenting end results. This paper argues that the utility of visualization approaches extends beyond these limits as it plays key role in fields of exploration, analysis and presentation, which enhances planner\u27s capabilities to solve complex planning problems. It proposes a transdisciplinary method that combines visualization approaches to site selection, integrated with spatial scenario planning, and stakeholder participation. However, it focuses on visualization as it relates to spatial data, to be applied to all the stages of problem-solving in geographical analysis, from development of initial hypotheses, through knowledge discovery, analysis, presentation and evaluation. It uses three different spatial scenarios – nature conservation, residential expansion, and sustainable development- to investigate the potentials of GIS based visualization to develop maps of a range of plausible future for possible quarrying locations in Lebano

Phenotyping and Molecular Characterization of Extended-Spectrum Beta-Lactamases among Clinical Isolates of Gram-Negative Bacilli in Arar Tertiary Care Hospital, Saudi Arabia

Objectives: The emergence of extended-spectrum β-lactamases (ESBLs) in drug-resistant Gram-negative bacilli isolates in critically ill patients is posing a serious threat. Lack of data on the prevalence of drugresistant Gram-negative bacilli with respect to enzymes responsible for drug resistance in the tertiary care hospital at Arar necessitated this study.Methods: All the Gram-negative bacilli isolated from clinical specimens were subjected to antibiotic susceptibility testing. Drug-resistant organisms were screened for the presence of ESBLs, and confirmed by phenotypic methods. Molecular characterizations of these organisms were performed by conventionalPCR to identify the ESBLs genes.Results: A total of 3711 specimens were processed over a period of one year and 428 Gram-negative bacilli (GNB) were isolated. Out of 428 GNB, 91 (21.2%) were ESBL producers which include Escherichia coli (46), Klebsiella pneumoniae (33), Proteus mirabilis (11), and Klebsiella oxytoca(1). The minimum inhibitory concentration (MIC) for ceftazidime and ceftazidime plus clavulanic acid for all the ESBL (91) isolates were >16 μg/mL and 32 μg/mL and <0.25 to 0.5 μg/mL respectively. CTX gene 44(48.3%), was predominant among all ESBL producers; next to it was SHV 15(16.5%) and TEM 2(2.2%), and 30(32.9%) isolates had all the three genes (CTX, SHV, and TEM).Conclusion: The findings in our study revealed the higher prevalence of ESBL in the community. Surveillance of antibiotic resistance with respect to ESBLs will provide a platform for framing antibiotic policy

Bilateral Lower Limb Disabling Claudication in a Young Man: A Case of Mönckeberg’s Arteriosclerosis

Mönckeberg’s arteriosclerosis, also called medial calcific sclerosis or Mönckeberg’s sclerosis, is a form of vessel hardening due to increased calcium deposits in the tunica media layer. There is disagreement over its clinical significance and aetiology and its relation to atherosclerosis and vascular calcification. Its clinical presentations and treatment are still debated. More effort should be directed on attempting to distinguish between atherosclerotic lesions and Mönckeberg’s lesions on the basis of age, location and the pattern of calcifications where there is considerable overlap between intimal or medial and involvement of the internal elastic lamina border between those planes. In-depth research is still needed to create consensus guidelines for the diagnosis and management of this condition. This article includes a review of the literature and a case report of a 22-year-old man with the condition

BIM-based facility management models for existing buildings

Building Information Modeling (BIM) is mainly used for the design and construction of new buildings. However, one of the main challenges facing BIM adoption for existing or old buildings constructed without consideration for their modeling is obtaining raw and accurate building data and converting it to the BIM model. Based on this challenge, this study develops a framework that uses different data capture techniques for existing buildings and then transforms this captured data into 3D BIM models, through which it can improve its management processes as facilities during their service life. Specifically, 3D laser scanning techniques were used to capture indoor building data, while drones equipped with high-definition cameras (UAV) were used to capture outdoor building data such as geometric dimensions, material shapes, surfaces, and various shapes. Then, the captured data was converted into a high-resolution 3D model. This has verified the accuracy of this engineering model by converting the two-dimensional engineering plans to three-dimensional through the well-known engineering design tools. Moreover, the 3D model has been integrated with the Web Based Building Management System (BMS) platform. This research framework helps in developing engineering facility management processes and modern digital transformation processes that aim at speeding up facility management during their service period using modern technologies. This study aims to develop current knowledge in the construction industry and facility management by reviewing a comprehensive understanding of how to use modern technologies to obtain various information to develop BIM models for existing and nonmodeled buildings in order to exploit and integrate them with advanced facility management systems and platforms, which constitutes a major progress in this field allowing to save a lot of effort and money in the future
