A historical development of the public secondary school curriculum in Saudi Arabia from 1930 to the present.
The traditional mathematics courses of algebra, geometry, and trigonometry have been integrated and the syllabus has been changed to what is termed the "new mathematics." Other courses of the secondary school program of studies have been in the initial stages of integration, including science, social studies, language studies, etc. The rigid system of examinations has been changed from the traditional pass/fail grading to a more flexible one based on the American system of education. The Ministry of Education has been gradually reorganizing its administrative structure, aiming at a long-range trail of decentralization. Gradually increasing autonomy has been granted to the educational districts.It was concluded that the recent influence and advice from educational agencies, such as UNESCO and from the west have been perceived by many Saudi Educators as a promising point of departure in moving the traditional system toward more flexibility and relevant education. However, the reinforcing of the traditional mores of the society and the persisting strict academic content of the program of studies more than anything else the fundamental problem facing education. It was further concluded that the curriculum defined narrowly as subject matter has reflected not only the aims and objectives of education but, has also influenced the development of the teaching method, the content of the courses and the examination system.The concepts of the comprehensive high school, the combined school, and the full-day work school have been introduced recently from the United States to provide an alternative education. Study groups in mathematics, science and social studies have been established, but their numbers, resources, activities, and financial status are limited.Related available literature reviewed included Ministry of Education documents, local newspapers, reports published by UNESCO and the United States educational agencies. Periodicals and books in Arabic and English were reviewed. Personal observations and informal discussions with various Ministry of Education, local educational district and secondary school personnel were important factors in the study.Although education in Saudi Arabia has been influenced by many foreign practices, it has maintained the main lines of its tradition and has remained true to its origins in Islamic principles. The development of education in general, and curriculum, in particular, was based on the Egyptian system of education. Reforms in education thereafter began to shift gradually toward the main lines of the British, then the American educational systems. This latter trend has been mainly a matter of copying the practices of the American system, rather than adopting the ideas of the system and suiting them to Saudi practice. By far, however, the most significant development occurred in the 1970's.The purpose of this study was to investigate the historical development of the Saudi Arabian educational system since its establishment in the 1930's with emphasis on the development of the secondary school curriculum (organization, program of studies, teaching methods, teacher education and examination system) that took place in the last two decades
Effects of Using Culture-laden Texts on Culture-specific Translation Skills in Arab Students
This work explores the possibility of translating culture-laden texts from English into Arabic, relying on a corpus of literary texts representing the local cultures of the 16th. and the 18th. century England. Furthermore, it taps into the applicability of SL cultural texts to help students appropriately render a culture-specific lexicon. The present study makes use of an experimental research design to check whether the use of literary texts may help EFL learners enhance their culture-specific translation skills in a traditional instruction setting. Finally, its findings indicate that the use of culture-laden literary texts can be efficient in introducing the culturally loaded lexicon of the English language, thereby inducing improvements in translational writing skills of EFL learners of translation
Orofacial Granulomatosis
Orofacial granulomatosis (OFG) is an uncommon chronic inflammatory disorder of the orofacial region. It is characterized by subepithelial noncaseating granulomas and has a spectrum of possible clinical manifestations ranging from subtle oral mucosal swelling to permanent disfiguring fibrous swelling of the lips and face. Etiopathogenesis is unknown. A range of systemic granulomatous disorders, including Crohn disease and sarcoidosis, may cause orofacial manifestations that cannot be distinguished from those of OFG. Treatment of OFG has proven difficult and unsatisfactory, with no single therapeutic model showing consistent efficacy in reducing orofacial swelling and mucosal inflammation
Comparison Between the Effects of Different Sources of Dietary Fiber on Blood Lipid Profile in Rats
This study was conducted to investigate the effect of different sources of dietary fiber on serum lipids and lipoproteins in Sprague-Dawley rats, namely total cholesterol (TC), Low-density lipoprotein cholesterol (LDL-C), high–density lipoprotein cholesterol (HDL-C) triglyceride (TG), and (HDL-C/LDL-C) ratio. The experimental diets included casein diet, untreated wheat bran diet, soaked wheat bran diet, Arabic white bread diet, lupine diet, chickpea and pectin diet. Each group of rats (6/group) was fed one of the seven prepared diets for 6 weeks. Untreated wheat bran has hypercholesterolemic effect since it significantly (p<0.05) increased TC, LDL-C and decreased HDL-C values as compared with treated bran diets. The soaking process lowered significantly (p<0.05) TC and LDL-C levels in comparison with casein diet. Chickpea diet had higher significant value of HDL-C than soaked wheat bran and lupine diets. However, it was not significantly different from casein and untreated wheat bran diet. In addition, Chickpea diet had a significantly higher HDL-C value than pectin diet. The values of HDL-C of the Lupine diet are not significantly different (p>0.05) from casein and pectin diets, but it has also decreased LDL-C. White bread was found to have no hypocholesterolemic effect in comparison with treated brans groups and control group; it raised TG, TC and LDL-C levels. Pectin had a similar behavior in a remarkable decrease blood TC and LDL-C cholesterol. White bread was found to have no hypocholesterolemic effect in comparison with treated brans groups and control group; it raised TG, TC and LDL-C levels. It is concluded that the behavior of cereals and legumes varies in its effect on cholesterol–lowering ability. Preparation of wheat bran foods by soaking improve some physiological characteristics of insoluble fibers, particularly lowering total cholesterol TC and low-density lipoprotein cholesterol LDL-C). Keywords: Dietary fiber, Arabic bread, Wheat bran, Soaking, Chickpea, Lupine, Pectin, Lipoproteins, Rat
Biomimetic Based EEG Learning for Robotics Complex Grasping and Dexterous Manipulation
There have been tremendous efforts to understand the biological nature of human grasping, in such a way that it can be learned and copied to prosthesis–robotics and dextrous grasping applications. Several biomimetic methods and techniques have been adopted, hence applied to analytically comprehend ways human performs grasping to duplicate human knowledge. A major topic for further study, is related to decoding the resulting EEG brainwaves during motorizing of fingers and moving parts. To accomplish this, there are a number of phases that are performed, including recording, pre-processing, filtration, and understanding of the waves. However, there are two important phases that have received substantial research attentions. The classification and decoding, of such massive and complex brain waves, as they are two important steps towards understanding patterns during grasping. In this respect, the fundamental objective of this research is to demonstrate how to employ advanced pattern recognition methods, like fuzzy c-mean clustering for understanding resulting EEG brain waves, in such a way to control a prosthesis or robotic hand, while relying sets of detected EEG brainwaves. There are a number of decoding and classification methods and techniques, however we shall look into fuzzy based clustering blended with principle component analysis (PAC) technique to help for the decoding mechanism. EEG brainwaves during a grasping and manipulation have been used for this analysis. This involves, movement of almost five fingers during a grasping defined task. The study has found that, it is not a straight forward task to decode all human fingers motions, as due to the complexity of grasping tasks. However, the adopted analysis was able to classify and identify the different narrowly performed and related fundamental events during a simple grasping task
Role of Laser Produced Silver Nanoparticles in Reversing Antibiotic Resistance in Some MultidrugResistant Pathogenic Bacteria
Silver nanoparticles (Ag NPs) were produced through nanosecond laser in deionized water. These nanoparticles were characterized by UV–VIS spectrometer and transmission electron microscopy. VITEK®2 compact system was used to identify Escherichia coli (ESBL strain) and Staphylococcus aureus (MRSA strain) as multidrug-resistance (MDR) bacteria. The antibacterial activity of Ag NPs, ampicillin (AMP), and their combinations was tested against both bacterial isolates through standard microbiological culturing techniques. Our data show that both of E. coli and S. aureus were highly resistant to AMP. Ag NPs alone reduced growth in both bacterial isolates considerably. Growth declined drastically in both bacteria when AMP was used in combination with Ag NPs. The minimal inhibitory concentration of combined agents for E. coli was 20 µg/ml Ag NPs + 1 mg AMP/ml and for S. aureus was 10 µg/ml Ag NPs + 1 mg AMP/ml. The results show that the Ag NPs have great potentials in enhancing the antimicrobial activities of drugs that used to be ineffective against MDR bacteria. Administering combinations of antibiotic(s) with AgNPs may help in treating patients suffering from infections caused by MDR bacteria. Further in vivo and in vitro investigations are required to evaluate the side effects of these combinations
