Assessment of risk management and control measures against coronavirus disease

This article presents the COVID-19 situation and control measures taken by the Government of Pakistan. Two waves of pandemic are faced globally and similar in the study area. We have investigated the risk management decision in two phases. Primarily, strict lockdown was observed from March 2020 to July 2020 and smart lockdown was enforced from August 2020 to December 2020. It has been studied that during strict lockdown, COVID cases reduced gradually but reopening of institutes and smart lockdown strategy resulted gradual increase in confirmed cases and death rates. During first wave of COVID-19 in Pakistan, a total confirmed number of patients of COVID-19 were 263,496 till 18th of July 2020 with total deaths of 5,568 people and 204,276 recoveries, while total number of COVID-19 patients reached 555,511 till 9th of February 2021 with total deaths of 12,026 people. Province of Sindh was affected badly with total number of 251,434 COVID-19 cases followed by Punjab Province with total number of 161,347 COVID-19 till 9th of February 2020.

流式细胞仪的原理、应用及最新进展

流式细胞术是一种采用激光束激发单行流动的细胞,对它的散射光和携带的荧光进行探测,从而完成细胞分析和分选的技术。以流式细胞术为核心技术,流式细胞仪集光学、电子学、生物学、免疫学等多门学科和技术于一体,能够高效分析微小颗粒(如细胞,细菌)的先进科技设备。它对社会产生了深远的影响,成为了科学研究的必要工具。最近几年,流式细胞仪取得了长足进步。为了深入的了解它,本文从流式细胞仪的工作原理和技术指标,在临床医学、生物学、生殖学和制药学中的应用,以及它的世界格局、仪器功能的最新进展三方面,进行了简明、扼要的论述。展望未来:功能专业化、自动化,体积小型化,多色多参数分析能力提高和分析分选速度更快成为流式细胞仪发展的趋势。     

Factors influencing the social acceptability of large carnivore behaviours

A survey on attitudes toward large carnivores was conducted in a representative sample of the Norwegian population (n = 3134). People were asked about the acceptability of carnivores living in remote wilderness, close to where people live, killing livestock, killing pets, or threatening humans. Large differences in acceptability appeared across the five situations. Wolves and bears were less acceptable than lynx and wolverines when observed close to where people live. Negative associations were found between acceptability and lack of personal control, economic loss, and respondents' age. Acceptability was higher among males than among females, and higher among urban than among rural residents. The results showed that general measures of attitudes alone toward large carnivores were of limited value in wildlife management. The situational and social specificity of these attitudes should be given more attention.

军队医院文职人员职业性质及社会地位现状的调查研究

目的:分析军队医院文职人员的社会性质及地位,调查现役干部对文职人员性质地位的认知情况,为开设针对性的教育管理工作提供理论指导。方法:对我院56名现役干部和78名文职人员进行问卷调查,对结果进行汇总研究,分析医院文职人员的现状及干部对其性质地位的认知情况。结果:现役干部对文职人员缺乏足够的理解,存在受阻、延迟和弱化的现象;文职人员本身由于对自身权利义务认识不足以及在情感上难以融入军营,身份认同存在难度。结论:提高对军队文职人员的认识,充分发挥军队文职人员队伍的作用,必须提升文职人员的社会效应,加强教育管理,完善培养机制,多方面提升对军队文职人员的认知。

浅析临床专业影像学教学现状与改革

医学影像学是一门新兴学科,同时也是一门发展迅速的学科。目前影像学技术已进入全新的数字影像时代,代表着临床医学发展中的热点潮流,同时也推动了医学的发展。医学影像学是医学高等教育中的重要内容,涉及到人体各个系统、各种疾病,内容多、范围广;然而近年来,随着各种影像设备的不断更新,影像技术的迅猛发展,医学高校的影像学教育明显滞后于该学科的发展速度,传统影像学教学模式也已经很难满足学习的需要。本文根据已有的研究资料及师生反馈的信息,分析临床医学专业影像学的教学现状与改革方向,以期提高对其教学方法的认识,适应医学影像学的快速发展,提高教学质量。     

湖北后河国家级自然保护区生物多样性及其保护对策 II.生物多样性保护现状、威胁及其对策

湖北后河自然保护区拥有丰富的生物多样性,为中国生物多样性三大关键地区之一的川东-湘鄂西关键地区的重要组成部分。但所处的贫困山区少数民族县长期以来以森工产业为其县域经济的主要支柱,长期的木材采伐和狩猎习俗曾对该保护区的生物多样性带来了严重破坏。自然保护区的建立使其生物多样性逐渐得到了有效保护,特别是升为国家级自然保护区后,生物多样性保护进入了一个新阶段。但该保护区的生物多样性依然面临多种威胁,保护区自身科学研究力量的薄弱和保护区面积相对较小,限制着该区域生物多样性的进一步研究和保护。进一步扩充保护区面积、引进科研力量并提升自身人员科研素质、协调并增强区内外社区共管是该区生物多样性得到进一步保护和恢复的当务之急。
