تسعى المحاسبة الى مسايرة القفزات الهائلة والمتسارعة في تطور العلوم الصرفة والتطبيقية والتقدم التكنولوجي، والتي ادت على ظهور مفاهيم جديدة الغت مسلمات وبديهيات كانت سائدة لمدة طويلة، فعلى سبيل المثال: كان مخزون المواد الاولية والبضاعة التامة في المؤسسات الصناعية او التجارية يشكل العمود الفقري لها بتكاليفه ومشاكله، حتى اذا ما جاء نظام (JIT) الغى بتطبيقاته هذه المفاهيم واعتمد مفهوماً جديداً هو (الانتاج من اليد الى الفم)، وان مفاهيم الكلفة والتسعير تخلخلت وتقادمت بظهور فلسفة سوق المنافسة الحرة والعولمة، واصبح الزبون هو القاسم المشترك والاساس لنجاح كل المؤسسات او فشلها فإذا لم يرض الزبون بمنتج ما بسبب تغير اذواقه او ميله الاستهلاكي فلا فائدة من انتاج البضاعة حتى لو كانت بأساليب مثالية. وقد كان للتطورات التكنولوجية اثر كبير في السلع والمنتجات فظهور منتجات جديدة في السوق يؤدي الى تزايد الطلب على سلعة معينة، وتخفيض الطلب على سلعة اخرى. ولذلك فقد ظهرت مسألة خطيرة في هذا المجال وهي الاندثار بالتقادم او ما يسمى بالاندثار التقني. فالقفزة النوعية تتمثل في ان هذا الاندثار يؤدي الى صرف مبالغ هائلة في موضوع البحث والتطوير لغرض تصميم منتجات جديدة تساير اذواق المستهلكين، اذ اصبحت السلع تتقادم شهرياً او خلال مدد قصيرة.

ان الاساليب الادارية الحديثة دائماً تسعى للحاق بعجلة التقدم العلمي، فأوجدت نظريات ومفاهيم تتلاءم مع هذا التطور وكان لزاماًَ على المحاسبة- وخاصة محاسبة التكاليف والمحاسبة الادارية- تأطير هذه النظريات بما يخدم اهدافها.

ومن هنا جاءت مفاهيم هندسة القيمة وإعادة هندسة العمليات بوصفها احد ابرز الاساليب الادارية والتقنية الحديثة الملائمة لمواكبة التقدم العلمي والتغيرات في بيئة الاعمال لتحقيق الهدف الرئيس الذي تسعى اليه المؤسسات اليوم وهو تلبية متطلبات ورغبات الزبون من خلال تحقيق هدفي: تخفيض كلفة المنتج وتحسين قيمته لنيل رضاه، وهو المقياس الأساس لنجاح المؤسسات، ولذلك فإن هذا البحث يسعى الى بيان اهمية ودور الاسلوبين موضوعي البحث في تحقيق عوامل النجاح الأساسية للمنافسة حيث تعد هندسة القيمة اسلوباً مختلفاً في معالجتها للتكاليف المرتفعة للمنتج بتركيزها على تجزئة المنتج على وظائف ومكونات، ودراستها وتحليلها. اما أسلوب إعادة هندسة العمليات فركز على حاجة المنشآت الى تغيير عملياتها وانشطتها.

Recycling of Chicken Egg Shells into Nanopowder: Synthesis, and its Properties
...Show More Authors

Increase in unconventional resources of calcium (Ca+2) for fowls, aquaculture and native animals was improved. This work was planned to define the most polymorph of calcium carbonate (CaCO3) that take place in the two types of chicken eggshells (local and imported type). In this research, the comparative analysis of calcium carbonate (CaCO3) content was approved for nominated eggshells of native strain and imported chicken via Field Emission Scanning Electron Microscope (FESEM), Transmission Electron Microscope (TEM), Fourier-Transform Infrared Spectroscopy (FTIR) and Powder X-Ray Diffraction (PXRD) analysis. The results demonstrate that native and imported chicken eggshells comprise calcite morph that ha

Ischemic Stroke and Autophagy: The Roles of Long Non-Coding RNAs
...Show More Authors
:

Ischemic stroke is a significant cause of morbidity and mortality worldwide. Autophagy, a process of intracellular degradation, has been shown to play a crucial role in the pathogenesis of ischemic stroke. Long non-coding RNAs (lncRNAs) have emerged as essential regulators of autophagy in various diseases, including ischemic stroke. Recent studies have identified several lncRNAs that modulate autophagy in ischemic stroke, including MALAT1, MIAT, SNHG12, H19, AC136007. 2, C2dat2, MEG3, KCNQ1OT1, SNHG3, and RMRP. These lncRNAs regulate autophagy by interacting with key proteins involved in the autophagic process, such as Beclin-1, ATG7, and LC3. Understanding the role of lncRNAs in regulating auto

Image encryption algorithm based on the density and 6D logistic map
...Show More Authors

One of the most difficult issues in the history of communication technology is the transmission of secure images. On the internet, photos are used and shared by millions of individuals for both private and business reasons. Utilizing encryption methods to change the original image into an unintelligible or scrambled version is one way to achieve safe image transfer over the network. Cryptographic approaches based on chaotic logistic theory provide several new and promising options for developing secure Image encryption methods. The main aim of this paper is to build a secure system for encrypting gray and color images. The proposed system consists of two stages, the first stage is the encryption process, in which the keys are genera

Single Channel Fetal ECG Detection Using LMS and RLS Adaptive Filters
...Show More Authors

ECG is an important tool for the primary diagnosis of heart diseases, which shows the electrophysiology of the heart. In our method, a single maternal abdominal ECG signal is taken as an input signal and the maternal P-QRS-T complexes of original signal is averaged and repeated and taken as a reference signal. LMS and RLS adaptive filters algorithms are applied. The results showed that the fetal ECGs have been successfully detected. The accuracy of Daisy database was up to 84% of LMS and 88% of RLS while PhysioNet was up to 98% and 96% for LMS and RLS respectively.

Kinetic and Mechanism of Oxidation of Oxalic Acid by Cerium (IV)
...Show More Authors

Kinetic and mechanism studies of the oxidation of oxalic acid by Cerium sulphate have been carried out in acid medium sulphuric acid. The uv- vis. Spectrophotometric technique was used to follow up the reaction and the selected wavelength to be followed was 320 nm. The kinetic study showed that the order of reaction is first order in Ce(IV) and fractional in oxalic acid. The effect of using different concentration of sulphuric acid on the rate of the reaction has been studied a and it was found that the rate decreased with increasing the acid concentration. Classical organic tests was used to identify the product of the oxidation reaction, the product was just bubbles of CO2.

ISOLATION AND IDENTIFICATION OF BIOFILM PRODUCING ENTEROCOCCUS FAECALIS FROM ROOT CANAL
...Show More Authors

This study was aimed to one of the most prevalent causes for endodontic treatment failure is the presence of Enterococcus faecalis bacterium within teeth root canals. To achieve successful treatment, it is so important to study E. faecalis behavior. The aim of study was to investigate biofilm production and antibiotic sensitivity of E. faecalis isolated from root canals. Results showed isolation of E. feacalis (65%) of samples, identified by specific gene by PCR technique. Most isolates were sensitive to Imipenem and resistant to Erythromycin, Clindamycin, Tetracycline and Trimethoprim. Strong biofilm production was detected among 29.5% of highest antibiotic resistant isolates. The results may indicate that infected root canals with E. feac
