Evaluation of Diagrams in Science Textbooks for Middle school in The Kingdom of Saudi Arabia: تقييم الرسوم التوضيحية في كتب العلوم للمرحلة المتوسطة في المملكة العربية السعودية

The aim of the current research is to determine the extent to which the images, drawings and tables included in science textbooks for all middle school grades meet the textbooks standards, which are: (appropriateness of the shape's position to the concept, clarity and attractiveness of the colors, titles, size, realism, density of shapes, clarity, adequacy of number). To achieve the research goal the descriptive analytical approach was used, The research ppopulation consisted of all science textbooks for middle school (6) textbooks of the edition (2019). The results showed that the highest standard for images is: (titles) by (69%), and the highest standards for drawings are: (appropriateness of the shape's position to the concept, clarity and attractiveness of the colors, titles, density of shapes, clarity) by (40%), while the highest standard for tables is: (realism) by (16%). As for the least applicable standard in the images is (size) by (46%), and the least applicable standards in the drawings are (appropriateness of the shape's position to the concept, clarity and attractiveness of the colors) by (27%), and the least standards that applies to the tables are (clarity and attractiveness of the colors, and appropriateness of the shape's position to the concept) by (7%). In light of the results, it was recommended that attention should be paid to image standards (size, clarity and realism), as well as the need to pay attention to drawings standards (appropriateness of the shape's position to the concept, clarity and attractiveness of the colors, titles, density of shapes, clarity, and adequacy of number), as well as the need to pay attention to tables standards (appropriateness of the shape's position to the concept, clarity and attractiveness of the colors, titles, density of shapes, clarity, and adequacy of number) in science textbooks for the middle school.

Management of valves to improve performance reliability of distribution systems

The overall reliability of a distribution system depends largely on valve reliability, location, and adequacy of number as well as the frequency of water main failure. Therefore, valve management is an essential aspect of distribution system management. This article details how a computer application, the Strategic Valve Management Model (SVMM), can be used to identify pipe segments associated with pipe breaks, determine valves to isolate the breaks, and perform analyses of valve management alternatives (including present worth costs) to reduce customer service interruptions. Valve management alternatives include the addition of new valves, improvement of valve reliability by exercising valves, or a combination of the two. A set of simple performance indicators was developed to evaluate the performance of valve isolating systems. This article demonstrates applications of the SVMM to hypothetical and actual water distribution systems.

A Review of Geriatric Education in Singapore

The United Nations has identified the training and education of healthcare professionals and care providers involved in the care of older persons as a global priority. Singapore is no exception as it faces a rapidly ageing population. Older people have many medical needs of varying dimensions and their care requires a multidisciplinary healthcare team. The current status of geriatric education of health professionals involved in elderly care in Singapore is discussed in this paper. Important issues raised include the disparity between professions in the stages of development of geriatric education, questions on the adequacy of numbers and training of healthcare professionals providing geriatric care, as well as the need for geriatric education of caregivers.
