| 1 | 面向对象技术在电力系统仿真建模中的应用显示文摘电力系统现存的大部分仿真软件基本上使用的是面向功能或面向结构图方法开发的 ,由于这两种方法本身的局限性 ,对这些软件的功能增强和维护非常困难。为了克服这种困难 ,文中描述了采用面向对象方法在电力系统数字仿真建模中的应用 ,将面向对象程序设计方法中的突出优点 ,如封装性、继承性和多态性应用在电力系统仿真中。通过应用面向对象设计方法 ,使设计出的软件尽可能直接地描述现实世界 ,构造出模块化的、可重用的、维护性好的软件。 | 朱明春 范瑜 吴命利 Mahamat Adam | 2002 | 计算机仿真2002，19，4： | 8 |
| 2 | 物流配送中心的选址研究显示文摘时至今日,现代市场竞争逐趋激烈,不同企业发展均需面对怎样降低成本、提升服务质量的重要任务,而对于新兴物流企业而言,这一任务尤为迫切。整个物流活动流程中,选址为极为关键的环节之一。物流系统中,配送中心的选址合理性,对现代化物流活动有重要影响。为此,对物流配送中心的选址问题予以关注和重视,对有效节约资源,实现物流系统的高效均衡发展而言意义重大。本文基于物流配送中心的相关概念,从物流配送中心选址原则、选址方法以及选址过程需要考虑的因素几个方面出发对物流配送中心的选址问题进行讨论。 | Mahamat Ali Hisseine | 2019 | 现代经济信息2019，0，2： | 2 |

| 9 | Global prevalence of hepatitis B virus serological markers among healthcare workers:A systematic review and meta-analysis显示文摘BACKGROUND The hepatitis B virus(HBV)infection is a global public health concern that affects about 2 billion people and causes 1 million people deaths yearly.HBV is a bloodborne disease and healthcare workers(HCWs)are a high-risk group because of occupational hazard to patients’blood.Different regions of the world show a highly variable proportion of HCWs infected and/or immunized against HBV.Global data on serologic markers of HBV infection and immunization in HCWs are very important to improve strategies for HBV control.AIM To determine the worldwide prevalence of HBV serological markers among HCWs.METHODS In this systematic review and meta–analyses,we searched PubMed and Excerpta Medica Database(Embase)to identify studies published between 1970 and 2019 on the prevalence of HBV serological markers in HCWs worldwide.We also manually searched for references of relevant articles.Four independent investigators selected studies and included those on the prevalence of each of the HBV serological markers including hepatitis B surface antigen(HBsAg),hepatitis e antigen(HBeAg),immunoglobulin M anti-HBc,and anti-HBs.Methodological quality of eligible studies was assessed and random-effect model meta-analysis resulted in the pooled prevalence of HBV serological markers HBV infection in HCWs.Heterogeneity(I²)was assessed using theχ²test on Cochran’s Q statistic and H parameters.Heterogeneity’sources were explored through subgroup and metaregression analyses.This study is registered with PROSPERO,number CRD42019137144.RESULTS We reviewed 14059 references,out of which 227 studies corresponding to 448 prevalence data among HCWs(224936 HCWs recruited from 1964 to 2019 in 71 countries)were included in this meta-analysis.The pooled seroprevalences of current HBsAg,current HBeAg,and acute HBV infection among HCWs were 2.3%[95% confidence interval(CI):1.9-2.7],0.2%(95%CI:0.0-1.7),and 5.3%(95%CI:1.4-11.2),respectively.The pooled seroprevalences of total immunity against HBV and immunity acquired by natural HBV infection in HCWs were 56.6%(95%CI:48.7-63.4)and 9.2%(95%CI:6.8-11.8),respectively.HBV infection was more prevalent in HCWs in low-income countries,particularly in Africa.The highest immunization rates against HBV in HCWs were recorded in urban areas and in high-income countries including Europe,the Eastern Mediterranean and the Western Pacific.CONCLUSION New strategies are needed to improve awareness,training,screening,vaccination,post-exposure management and treatment of HBV infection in HCWs,and particularly in low-income regions. | Gadji Mahamat Sebastien Kenmoe Etheline W Akazong Jean Thierry Ebogo-Belobo Donatien Serge Mbaga Arnol Bowo-Ngandji Joseph Rodrigue Foe-Essomba Marie Amougou-Atsama Chavely Gwladys Monamele Chris Andre Mbongue Mikangue Ginette Irma Kame-Ngasse Jeannette Nina Magoudjou-Pekam Cromwel Zemnou-Tepap Dowbiss Meta-Djomsi Martin Maidadi-Foudi Sabine Aimee Touangnou-Chamda Audrey Gaelle Daha-Tchoffo Abdel Aziz Selly-Ngaloumo Rachel Audrey Nayang-Mundo Jacqueline Felicite Yengue Jean Bosco Taya-Fokou Lorraine K M Fokou Raoul Kenfack-Momo Dimitri Tchami Ngongang Efietngab Atembeh Noura Herve Raoul Tazokong Cynthia Paola Demeni Emoh Cyprien Kengne-Nde Jean Joel Bigna Onana Boyomo Richard Njouom | 2021 | World Journal of Hepatology2021，13，9： | 1 |

| 18 | Quasi-Local Energy Distribution and Thermodynamics of Reissner-Nordstrom Black Hole Surrounded by Quintessence显示文摘We investigate quasi-local energy distribution and thermodynamics of the Reissner-Nordstrm black hole space-time surrounded by quintessence.We use the quasi-local energy distribution from Einstein energy-momentum complex.We plot the variation of the energies,temperature and heat capacity with the state parameter related to the quintessence ω_q.We show that due to the presence of quintessence,the total energy of the outer region as well as the temperature and heat capacity decreases with the increase of the density of quintessence,while the total energy of the black hole region increases. | Mahamat Saleh Bouetou Bouetou Thomas Timoleon Crepin Kofane | 2011 | Communications in Theoretical Physics2011，55，2： | 1 |
