Abstract

One of the major things that cannot be dispensed with in every educational institution is the schedule of lessons. The aim of this research is to develop an Expert System in Visual Prolog for Weekly Time Table (ESWTT). The suggested ESWTT mainly consists of two phases. The first phase is responsible for automatic acquiring of human expert knowledge. The second phase is concerned with the construction of time table from the entered knowledge by using forward chaining method (data driven interface). When ESWTT tested by experts and end users, it was found that ESWTT performance in constructing KB and building the table was exact (the building ability of ESWTT is 100 %.). The same technique could be used to build Expert System Shell based on any other educational departments, mathematics, physics, etc.,). The only difference is to acquire knowledge suitable to the desired department.

من الأمور الرئيسية التي لا يمكن الاستغناء عنها في كل مؤسسة تعليمية الجدول الزمني للدروس. الهدف من هذا البحث هو تطوير نظام خبير بلغة برمجة فيجيوال برولوك للجدول الأسبوعي. النظام المقترح (ESWTT) يتكون أساسا من مرحلتين. المرحلة الأولى هي المسؤولة عن الاكتساب التلقائي لمعرفة الخبراء. المرحلة الثانية تعنى ببناء الجدول الزمني من المعرفة التي أدخلت باستخدام طريقة التسلسل إلى الإمام (forward chaining) أو ما تسمى بواجهة البيانات المدفوعة (data driven interface). عند اختبار منظومة (ESWTT) من قبل الخبراء والمستخدمين النهائيين تبين إن كفاءة (ESWTT) في بناء قاعدة المعرفة وفي بناء الجدول الزمني للدروس الأسبوعية هو 100%. نفس التقنية يمكن أن تستخدم في بناء واجهات خبيرة لبقية الأقسام التعليمية ألأخرى (الرياضيات، الفيزياء،...الخ.) والفرق الوحيد هو باكتساب المعرفة الخاصة بكل قسم.

Abstract

Knowledge-based economy becomes a common place among policy markers and main stream economists. The shift to a digital knowledge-based economy, prompted by new goods and services, will be a powerful engine for growth, competitiveness and jobs. In addition, it will improve citizen’s quality of life and environment. It enables us to discard some meanings and practices and retain others. Knowledge-based economy exhibits a dynamics different from a market economy. No organization can remain static and survive. Internal and external forces will provide or destroy opportunity and only those organizations equipped with technological infrastructure and strategy to economically exploit all facets of their knowledge will flourish

اصبح مفهوم الاقتصاد المبني على المعرفة منشرا بين راسمي السياسات الاقتصادية والسياسيين على حد سواء. فالانتقال إلى هذا المفهوم من الاقتصاد مصحوب بتوفير سلع وخدمات يمثل محركا قويا للنمو والمنافسة وخلق الوظائف وفرص العمل. كما انه سوف يحسن نوعية الحياة للمواطنين وللبيئة التي يعيشون فيها. هذا الانتقال سوف يمكن من إهمال بعض المفاهيم والممارسات الشائعة والاحتفاظ بغيرها. إن الاقتصاد المبني على المعرفة يمثل ديناميكية مختلفة عن تلك التي يمثلها اقتصاد السوق. فلا يمكن لأي كيان اقتصادي (منظمة فردية أو جماعية) أن يعيش ويتطور إذا ما بقي ساكنا، ذلك لان قوى داخلية وخارجية سوف توفر أو تفوت فرصة، ومن يستطيع البقاء والتطور في السوق هو ذلك الكيان (المنظمة) الذي تتوافر له بنية تحتية تكنولوجية وستراتيجية للاستغلال الاقتصادي لأوجه المعرفة المتاحة له. إن ثروتنا الحالية تتمثل بما نعرف عن ما يعمل، والمعرفة موجودة في عقول الناس العارفين المهم كيف يمكن هؤلاء العارفين من المساهمة في رسم السياسات المناسبة للمنظمة التي يعملون فيها والاحتفاظ بهم كموجودات مهمة لدى المنظمة وخلق البيئة المناسبة لممارسة وتطوير معارفهم.

Abstract

Background: Oral health knowledge is important for promotion and maintenance of oral health. This study aims tofind out the difference in oral health knowledge and behavior of medical and dental students in technical medicalinstitute in Baghdad governorate.Materials and Methods: A questionnaire survey was carried on 202 Iraqi students in technical medical institute of BabAl-Muadam quadrant in Baghdad governorate (92 dental students and 110 medical students). Students were invitedto complete a set of questionnaires on dental knowledge and behaviors that are related to oral hygiene and dentalvisits.Results: Highly significant differences were shown between medical and dental students related to dentalknowledge, dental students were found to have more dental knowledge than medical students. Concerning thetypical method for caries prevention, 90.2% of dental students compared to 35.5% of medical one were aware thatbrushing regularly, minimizing sweets, visiting the dentist and the use of fluoride are all effective means of avoidingcaries. For oral hygiene behavior, dental students were practicing twice daily tooth brushing, flossing and rinsing in aproportion greater than medical students. Irregular visits to the dentist were found to be common among bothmedical and dental students and toothache was the major factor for dental visits in both groups. The lecturers werefound to be the most effective source of dental information for dental students, while the most effective source ofinformation for medical students was the family.Conclusion: The results of this study indicate that knowledge and behavior toward oral health and dental careespecially for the medical students need to be improved and there is a need for inclusion of oral health education inthe medical curriculum.
