Abstract:
Objectives: To study the clinicopathological pattern of gastric cancer in-cluding the location of the tumor in the stomach and to compare our results with other studies. Design: Prospective study of patients confirmed with gastric malignancy during the period from July 2016 to July 2017. Setting: Specialized center of gastrointestinal and liver diseases in Ibb city, Yemen. Subjects: All patients with histopathological confirmation of gastric malig-nancy. Results: During the study period, we had 69 patients with gastric cancer; among them 48 were males and 21 were females, with male: Female ratio is 2.2:1. The age ranged between 35 years and 90 years and the mean age was 65.87 ± 12.79 years. Most of the patients presented with epigastric pain (87%), weight loss (72.5%), pallor (65.2%), dysphagia (47.8%), vomiting (42%), palpable epigastric mass (20.3%) and hematemesis/melena (18.8%). The cardiofundal location was encountered in 33 cases (47.8% ), 22 (45.8%) males and 11 (52.4%) females, the corpus location in 24 cases (26%), 20 (41.7%) males and 4 (19%) females, the antral location in 8 cases (11.6%), 4 (8.3%) males and 4 (19%) females and the whole stomach in 4 cases (5.8%), 2 (4.2%) males and 2 (9.5%) females. Adenocarcinoma constituted about 94.2%, of which the intestinal type was 87.5% and the diffuse type was 12.5%. The non-epithelial tumor was encounter 4.3%, of which 2.9% were lymphoma and 1.4% were GIST. Conclusion: In our studied patients, proximally located gastric cancer was the most common in both sexes.
Disparity between Ideals and Reality in Curriculum Construction: The Case of the Lebanese English Language Curriculum  [PDF]
Kassim Ali Shaaban
Creative Education (CE) , 2013, DOI: 10.4236/ce.2013.412A2005
Abstract: This paper describes the disparity between the principles, guidelines, suggested themes, organization, methodology, classroom activities, and assessment outlined in the thematic, content-based English language curriculum adopted by the Lebanese government in 1997 and the classroom realities and other contextual factors that have hampered its proper implementation. The paper shows that the curriculum is designed in line with international ESL/EFL standards as it has clear goals, objectives, and performance indicators as well as sound perspectives on instruction, material selection and adaptation, and evaluation guidelines. These perspectives are based on widely accepted theoretical views in language acquisition and best practices in English language education. However, the content-based curriculum normally demands a high level of language proficiency and content and pedagogical knowledge from teachers, and it is highly dependent on the availability of adequate resources and ongoing professional development programs. The educational context in Lebanon still suffers the effects of the 1975-1990 civil war in these areas, which has made the implementation fraught with all sorts of problems.
Engineering, Project, and Production Management: Lessons
Kassim Gidado
Journal of Engineering, Project, and Production Management , 2013,
Abstract: This Journal always faces the challenge of bringing together the three disciplines in a common pool of management research. This edition provides at least a paper in each of the disciplines. Although each paper has a clearly defined focus in a specific discipline, the contribution of knowledge by each seems relevant to all three disciplines. This reinforces the need to further integrate the managerial aspects of the three disciplines for mutual benefits.
Pelaksanaan undang undang kangcu dalamkegiatan pertanian komersial di Negeri Johor
Kassim bin Thukiman
Jurnal Kemanusiaan , 2005,
Abstract: Pembangunan sesebuah negeri mempunyai kaitan yang rapat dengan kegiatan ekonomi. Kegiatan ekonomi berasaskan pertanian banyak menyumbang kepada pembangunan ekonomi di negeri Johor. Fenomena ini telah berlaku sebelum kedatangan British lagi. Apa yang menarik ialah pelaksanaan kegiatan ekonomi pertanian secara komersial berjalan secara sistematik berdasarkan pelaksanaan peraturan dan undang-undang. Sehubungan dengan itu, artikal ini berusaha untuk menelusuri pengenalan undang-undang yang dijalankan di negeri Johor sejak tahun 1844. Jelasnya, Johor bukan sahaja terkenal sebagai pusat pembangunan ekonomi, tetapi mempunyai kekuatan tersendiri dalam mengasaskan undang-undang. membangunkan sistem pentadbiran dan mengekploitasi kesuburan muka buminya. Sebab itulah Sultan (Maharaja) Abu Bakar telah dinobatkan sebagai Bapa Johor Moden.

A comparative study between friction stir welding and metal inert gas welding of 2024-t4 aluminum alloy
Haitham Kassim Mohammed
Journal of Engineering and Applied Sciences , 2011,
Abstract: In this paper, the mechanical properties of welded joints of 2024-T4 aluminum alloy obtained using friction stir welding (FSW) with four rotation speed (450,560,710 and 900 rpm) and conventional metal inert gas welding (MIG) are studied. FSW welds were carried out on a milling machine. The performance of FSW and MIG welded joints were identified using tensile, hardness, and microstructure. Properties FSW and MIG processes were also compared with each other to understand the advantages and disadvantages of the processes for welding applications of the Al alloy. Better tensile strength was obtained with FSW welded joints. The width of the heat affected zone of FSW was narrower than MIG welded joints. The results show that FSW improves the mechanical properties of welded joints.
Principal Component Analysis in Modelling Stock Market Returns
Kassim Haron,Maiyastri
Matematika , 2004,
Abstract: In this study, an alternative method to compare the performance of several GARCH models in fitting the KLCI daily rate of return series before and after the Asian financial crisis in 1997 using Principal Component Analysis (PCA) is sought. Comparison is then made with the results obtained from a known method based on the ranks of the Log Likelihood (Log L), Schwarzs Bayesian Criterion (SBC) and the Akaike Information Criterion (AIC) values. It is found that the best and the worst fit models identified by both methods are exactly the same for the two periods but some degree of disagreement, however, existed between the intermediate models. We also find that the proposed method has a clear edge over its rival because PCA uses actual values of the three criteria and hence the inability to exactly specify the relative position of each of the competing models as faced by the ranking method may be avoided. Another plus point is this method also enables models to be classified into several distinct groups ordered in such a way that each group is made up of models with nearly the same level of fitting ability. The two extreme classes of models are identified to represent the best and the worst groups respectively.
Robustness of D-optimal Design to Prior Parameter Estimates
Kassim Bin Haron
Matematika , 2002,
Abstract: This paper discusses the effect of errors in prior estimates on the efficiency of the D-optimal design used for estimating the parameters of a nonlinear regression model. The performance of the local D-optimal designs produced are evaluated by comparing their respective efficiencies of estimation, E(%). It was discovered that the D-optimal design is exceptionally robust to a wide range of initial parameter values and that over-estimating the parameters would consistenly produce a more efficient design than under-estimating them by the same quantum.
EM/Circuit Co-Simulation: A Highly Accurate Method for Microwave Amplifier Design
Syuhaimi Kassim,Fareq Malek
Universal Journal of Computer Science and Engineering Technology , 2010,
Abstract: This paper features a radical and highly accurate method of designing a microwave amplifier. A Full-wave Electromagnetic Simulator, which is based on the Method-of-Moments (MoM) numerical method, is used in parallel with the conventional microwave circuit simulator to demonstrate a superior performance outcome such as Stability, Return Loss and Small Signal Gain. This method known as EM/Circuit Co-Simulation guarantees a design that work with the first PCB and concurrently multiple PCB layouts are avoided, which saves design cost and development time respectively. The method is methodically demonstrated with the design of power amplifier (PA) based on E-pHEMT technology for IEEE 802.16e Mobile WiMAX applications.

Norizan M. Kassim
Journal of Internet Banking and Commerce , 2005,
Abstract: Financial liberalization and technology revolution have allowed the developments of new and more efficient delivery and processing channels as well as more innovative products and services in banking industry. Banking institutions are facing competition not only from each other but also from non-bank financial intermediaries as well as from alternative sources of financing, such as the capital markets. Another strategic challenge facing banking institutions today is the growing and changing needs and expectations of consumers in tandem with increased education levels and growing wealth. Consumers are becoming increasingly discerning and have become more involved in their financial decisions. For this reason, they are demanding a broader range of products and services at more competitive prices through more efficient and convenient channels. This study investigates the discrepancy between customer's expectation and perception towards the e-banking services.
