AN IMPROVED CROSS VENTILATION MODEL IN WINDY REGIONS

This study suggests a new simulated model to improve cross ventilation performance inside a single room space in the different wind velocity regions. The architectural design decisions of indoor openings and walls can achieve the stagnation and the Venturi conditions that can govern the indoor air velocities inside an indoor room space to be decreased in high wind velocity regions and to be increased in low wind velocity regions. Stagnation condition occurrence when an indoor wall faces an inlet opening can decrease indoor air velocities inside a single room space with a high indoor covered ventilation area because the spreading air mass movements have the curve shapes of the contour lines that indicate ratios of the outdoor wind velocity. Venturi condition occurrence when an inlet opening faces an outlet opening can increase indoor air velocities through the openings inside single room space with the high air flow rates because the penetrating air mass movements have the spire shapes of the contour lines that indicate ratios of the outdoor wind velocity. Hurghada City, Egypt, is selected as an example of windy regions while a single room space is selected as an example of indoor spaces for field and simulation experiments

YAG Laser in the Treatment of Nail Psoriasis: Clinical and Dermoscopic Assessment

Background: The Nd:YAG laser has emerged as a promising modality for the management of nail psoriasis owing to its ability for deep penetration of the skin surface, which has the advantage of destroying deep vessels. Objective: To assess the efficacy and safety of Nd:YAG laser in treating nail psoriasis. Methods: The present study was a randomized controlled study, conducted on 20 patients of both sexes (age older than 12 years) with mild to moderate psoriasis with nail involvement. We utilized facial telangiectasia parameters of Nd:YAG laser and beam diameter of 2.5 mm. Laser energy started with 110 J/cm2 in the first session and 130 J/cm2 in the rest of the sessions. Sessions were performed once monthly for up to 6 sessions. Results: We found no statistically significant difference in total Nail Psoriasis Severity Index (NAPSI) and nail bed scores before and after treatment among the treated group. However, there was statistically significant improvement in nail matrix score after treatment. On the other hand, the control group did not show any statistically significant changes for all scores throughout the study, except for the nail matrix score mean difference (0.35 ± 1.23 vs -1.00 ± 1.86 in the treated group). The degree of dermoscopic improvement was evident in the treated group (45% vs 25% in the control group). However, it was not statistically significant because of small sample size. The patients' satisfaction and the external investigator's assessment showed statistically significant negative correlation with total NAPSI mean difference in the treated group. Conclusion: The role of Nd:YAG laser in nail psoriasis is still controversial

Impact of Augmented Reality on Pattern Designing Using Origami-Style among Clothing and Textile Students

The study aimed to examine the effects of augmented reality technology on the development of origami-style pattern designing skills among female students in the clothing and textile field, as well as to explore their attitudes towards this technology. The quasi-experimental approach was employed to achieve the research objectives, with a sample of 24 female students from the Fourth Grade of the Department of Clothing and Textile, Faculty of Home Economics at Al-Azhar University. The participants were divided into two groups: a control group of 12 students who studied in the traditional way, and an experimental group of 12 students who used augmented reality technology to learn. The study was conducted in the second semester of the academic year 2020/2021. The results showed that there was a statistically significant difference (at a significance level of 0.01) between the average scores of the control group and the experimental group in both cognitive achievement and skill performance, with the experimental group performing better. Additionally, the retention of learned information was higher among the experimental group, and they had a more positive attitude towards using augmented reality technology in learning

Early Childhood Mathematics Curriculum in the light of the standards of the National Council of Mathematics Teachers

This study aims at exploring the preschool mathematics curriculum in light of the National Council of Teachers of Mathematics Standards. The study researched a sample of (140) preschool educators. An analysis of the mathematical content of preschool Self-Learning curriculum was conducted, and Saudi preschool educators were surveyed, in terms of their educational practices, and the processes used in teaching mathematics in their classes In accordance with the U.S. national standards for mathematicians, it means the methods in which children interact with sports content or content, namely (problem solving- communication- logical thinking - representation - Connection), where the study showed that the reality of the components of the mathematics curriculum applied in kindergartens within Saudi Arabia achieved these standards at these levels was The application of representation, communication and connectivity are the most achieved in the self-learning curriculum units with ratios of (86.4%, 83%, 82%), respectively, while problem-solving and logical thinking have reached the minimum use in the classroom, indicating that these processes are the least interested in application from the sample point of view, with 80%, respectively, using them (80%, 67.80%), despite the critical importance of these two processes specifically in building mathematical concepts as they focus on the ability of the child to be focused on the ability of the child. To use his accumulated sports skills to meet challenges such as predicting and examining hypotheses in order to find a scientific solution to the sports situation

The Role of Technology in Preventive Measures to Combat Money Laundering Crime: Case study Sudan

This study aimed to highlight the role that technology can play in the preventive measures to combat money laundering, especially since money laundering crimes have become dependent on advanced technical techniques in addition to many electronic means that are currently available. This necessitated the development of advanced technical means and tools to combat money laundering. The researchers used the case study methodology, which is characterized by many advantages that make it suitable for this study, including that it allows the collection of data from multiple sources. The study reached many results, the most prominent of which is that the phenomenon of money laundering passes in most of the stage of transfers through bank accounts, which must provide a degree of banking secrecy for customer accounts, which makes the matter of balancing between combating money laundering and maintaining the secrecy of customer accounts difficult and not Palliser. The most prominent of the recommendations of this study is that the legislation and laws of money laundering crimes must be revised and followed up with the necessary decisive, strict and rapid amendments, at least annually

Internet-based search of randomised trials relevant to mental health originating in the Arab world

BACKGROUND: The internet is becoming a widely used source of accessing medical research through various on-line databases. This instant access to information is of benefit to busy clinicians and service users around the world. The population of the Arab World is comparable to that of the United States, yet it is widely believed to have a greatly contrasting output of randomised controlled trials related to mental health. This study was designed to investigate the existence of such research in the Arab World and also to investigate the availability of this research on-line. METHODS: Survey of findings from three internet-based potential sources of randomised trials originating from the Arab world and relevant to mental health care. RESULTS: A manual search of an Arabic online current contents service identified 3 studies, MEDLINE, EMBASE, and PsycINFO searches identified only 1 study, and a manual search of a specifically indexed, study-based mental health database, PsiTri, revealed 27 trials. CONCLUSION: There genuinely seem to be few trials from the Arab world and accessing these on-line was problematic. Replication of some studies that guide psychiatric/psychological practice in the Arab world would seem prudent

Early Childhood Teachers Beliefs about Mathematics Teaching and Learning

The current research aimed to investigate the beliefs that early childhood teachers adopt about teaching and learning mathematics in the kindergartens of the Kingdom of Saudi Arabia. The teachers are role models for the child from whom he draws his knowledge, behavior, attitudes, concepts and experiences. and their classroom practice, which positively affects the level of the child and his attitudes towards the learning and teaching processes in general, and the mathematics course in particular, because of its importance in real life because it helps him to think, make decisions and solve problems he faces in his life. This has been confirmed by many researches and studies that the child is affected by his teachers beliefs, behaviors, decisions and dealings with him and the extent to which these beliefs are positive, which are the result of his personal and professional experience. One of the early childhood teachers, and the results of the study revealed that the responses of early childhood teachers about their beliefs about the processes of learning and teaching mathematics in general were positive, where most of the beliefs came to a large degree. This indicates that the teachers of this stage have positive opinions and ideas about the learning and teaching processes and the educational system, which affects their teaching efficiency, which is reflected in the child’s level of mathematics in an effective and positive manner. That is why the researchers recommend the necessity of providing workshops to develop, develop and support positive beliefs. The teachers of this stage are in line with modern educational trends
