Actual Practical Attitude and Knowledge of Dental Implants among Senior Dental Students and General Dentists Graduated from Some Saudi and Non-Saudi Dental Schools

Objective: To assess the actual practical attitude and knowledge of dental implants among senior dental students and general dentists graduated from some Saudi and Non-Saudi dental schools. Methods: A total of 300 senior dental students and general dentists participated in the study. Hard copies of the self-designed, multiple-choice questionnaires were distributed to all participants. The questionnaire consisted of 31 questions in five parts. Data were collected and analyzed using Chi-square test and t-test, where p Results: There is a statistically significant relationship between the participants’ answers, and their dental schools. Participants’ general knowledge, training, and teaching of dental implants, as well as information about restorations retained for the dental implants, were higher among participants from Saudi dental schools than participants from non-Saudi dental schools, while the information about dental implants was higher among participants from non-Saudi dental schools than participants from Saudi dental schools. Conclusion: We conclude that the actual practical attitude and knowledge of dental implants among participants in the current study was insufficient. Therefore, dental implant education in the undergraduate curricula of dental schools surveyed should be updated to include teaching, laboratory training, and preclinical and clinical training.

沙特某海水泵站水泵选型

沙特某大型海水泵站的设计、采购遵循API相关标准,项目的海水泵执行标准API 610.业主招标文件前端设计中规定海水泵按额定流量为55 000 m3/h对应扬程为16.1 m进行选型,但通过分析,得知招标文件中规定的主机容量不足;同时,投标阶段海水泵报价偏低,中标后承包商存在商务风险.为了解决技术商务风险,详细的设计通过对泵站前后水位变化情况进行分析,并优化设计,海水泵按正常流量为50 000 m3/h对应扬程为16.1 m进行选型.优化后,导叶体式混流泵运行流量范围为50 000~59 100 m3/h,效率为85%~87%,效率曲线平缓,运行范围位于高效区.优化后主机容量满足项目要求.海水泵由抽出式结构优化为非抽出整体式结构.

伊斯兰世界联盟与沙特阿拉伯关系论析

基于伊斯兰教与国家政权之间的制度性、结构性联系,国际伊斯兰非政府组织与资助国(本国)的关系十分紧密。伊斯兰世界联盟(伊盟)在资金、人事和意识形态等方面被沙特全面掌控,在战略、形象、行动等层面全方位为沙特政权服务,是沙特的利益维护者、形象塑造者、舆论引导者、行动参与者和职能承担者。伊盟与沙特的紧密关系给双方都带来了正负面双重影响。一方面,沙特的全方位支持使伊盟拥有雄厚的资源和实力,但这种全面掌控导致伊盟的非政府属性和独立性弱化,使其难以形成相对中立与公正的立场,带有明显的政治和宗教偏向,影响组织公信力,还造成伊盟的相对封闭性和保守性,导致其改革困难。另一方面,凭借非政府组织的身份优势,伊盟在为沙特开拓外交空间、减轻道义压力和提升国家软实力等方面发挥着特殊作用,但强烈的宗教属性、沙特偏向性及涉恐传闻给沙特国家形象带来困扰。未来,伊盟的发展取决于其能否处理好与沙特的关系,即在依托沙特资源的同时,增强自身主体性、自主性、中立性和公信力,处理好沙特政权与教权、宗教保守性与世俗现代化以及伊斯兰世界与西方世界的关系。

Epidemiology and Patterns of Malignant Lymphoma in Northern Saudi Arabia

Objective: The objective of this study was to appraise the epidemiology and patterns of malignant lymphoma in Northern Saudi Arabia. Methodology: A full reportage of data regarding malignant lymphoma was retrieved from the King Khalid Hospital, Hail, Northern Saudi Arabia, comprising records of malignant lymphoma from 2009 to 2016.

伊斯兰世界联盟参与全球治理研究

国际伊斯兰非政府组织是伊斯兰教参与全球治理的重要组织形式。基于宗教的情感资源和沙特的物质资源,伊斯兰世界联盟(伊盟)通过会议、出访、游说、倡议和援助等多种手段参与全球治理,包括宗教文化、反恐和去极端化、宗教事务管理、穆斯林少数族裔、跨宗教对话等领域,成为全球治理中的特殊力量。为维护世界和平、安全及稳定,塑造伊斯兰教良好形象和促进全球发展做出了贡献。但伊盟保守的意识形态、强烈的教派属性都影响其作为国际组织的中立性和公信力,对穆斯林少数族裔议题的介入也易造成对他国内政的干涉。同时,信息公开与对外合作程度不足都影响其参与全球治理的深度和成效,特别是诸多涉恐传闻影响组织形象及后续发展。伊盟的参与有助于伊斯兰因素融入全球治理之中,但它在全球治理中的角色依然只是参与者,更多表现为沙特参与全球治理的工具,组织主体性、独立性和能动性不足,发挥作用较为有限。未来,伊盟需在挖掘治理资源和提升治理能力上多做努力,可为全球治理贡献智慧和方案。
