1宫颈癌病人MR扩散加权成像较基于大小的T2WI与PET/CT逐个淋巴结的对照性研究显示文摘本研究的目的是以宫颈癌病人的PET/CT所见为标准.逐个淋巴结(LNs)比较ADC值诊断和T2WI的大小诊断标准。163例病人共339个短径大于5mm的盆腔LNs,比较PET/CT显示为阳性和阴性LNs的最小表观扩散系数(ADC)值、平均ADC值、长径和短径以及长短径比值(L/S值)。58例病人的118(35%)个LNsPET/CT为阳性。E.K.Choi J.K.Kim H.J.Choi S.H.Park B.W.Park N.Kim 郭雪梅 2009国际医学放射学杂志2009,32,5:19
2双源CT双能技术氙气通气CT的初步研究显示文摘研究经学院伦理委员会批准并有病人知情同意书。虽然氙(Xe)通气CT已经作为显示通气区域的一种潜在方法,但由于不同扫描时肺的不同容积造成的肺X线不同密度限制了Xe增强定量的应用。本研究的目的是评估利用双能技术进行Xe通气CT的可行性。12例受试者在吸入Xe后进行了双能CT扫描。使用了双能技术后,Xe的成分可被提出而不受肺容积的影响.可显示肺区域性动态与静态的通气功能,与薄层CT影像匹配精确。E.J.Chae J.B.Seo H.W.Goo N.Kim K.S.Song S.D.Lee 唐光健 2008国际医学放射学杂志2008,31,5:17

6CT结肠成像环状辐射线投射最小影像变形全内腔显示的三维影像诊断显示文摘此研究的目的是设计一个全景腔内显示技术.以影像变形极少的带状显示,明确其作为CT结肠成像(CTC)节省时间的主要三维显示方法的可行性。对照带状显示与其他4种三维显示方法显示10个10mm、10个20mm电子生成息肉影像的变形。52例病人行CTC检查.并于同天行结肠镜检查。对照2名独立读片医生利用带状显示与常规腔内显示的诊断操作与影像诊断时间。S.S.Lee S.H.Park J.K.Kim N.Kim J.Lee B.J.Park 唐光健 2009国际医学放射学杂志2009,32,5:0
7BMW公司i3增程器的控制分析和模型验证显示文摘基于试验数据,针对2014款BMW i3增程器(REX)进行了控制分析和模型验证。在美国阿贡国家实验室的先进动力总成研究所,置于环境仓的底盘测功装置上进行了车辆测试。BMW iREX是串联插电式混合动力增程车辆,其包括1台0.65L直列2缸增程发动机、1台26.6kW发电机、1台125kW的永磁同步交流电动机以及18.8kW·h的锂离子电池。包含热因素的部件和车辆模型均基于试验数据开发。例如,发动机油耗率、电池电阻或座舱暖通风与空调(HVAC)系统的能量消耗均受温度影响。另外在常温条件下(22℃环境温度)分析了车辆级控制策略。着重分析了发动机起/停策略、电池荷电状态(SOC)平衡和发动机运行工况。接着分析了基于环境状态(-7~35℃环境温度)或车辆状态(冷浸或热态)的控制策略差异。最后,介绍了基于高精度、直观的车辆仿真工具Autonomie的开发模型验证。在大多数热状态下,发动机油耗和电池SOC结果均在多次试验差异范围内。 W.Lee N.Kim K.Stutenberg A.Rousseau 王晓滕(译) 曲栓(译) 2019汽车与新动力2019,2,1:0
8Generalized Anxiety and Major Depressive Symptoms of General Public in South Korea during the Early COVID-19 Pandemic显示文摘The extent of viral spread and strategies in dealing with the COVID-19 pandemic have been different in each country.There are overall increased mental health concerns in many countries but it is unclear what the general public individuals who do not have heighten vulnerability to stressors for existing mental diseases or significant physical illnesses were experiencing during the pandemic.We evaluated the stressors and mental health of general public in South Korea that has a relatively low confirmed cases and deaths.Responses on the on-line survey questions were used to assess the mental and physical symptoms in association with individuals’reported stressors.Individuals with the symptoms of the generalized anxiety disorder(GAD)were reported in 58.9%,and major depression(MD)in 23.2%,mostly in minimal to mild degrees,cut-off scores of 5 and 10,respectively by the validated screening tools,GAD-7 and PHQ-9.Both GAD and MD symptoms were in 21.5%of the respondents.The total number of stress had significant association with the scores of GAD-7,PHQ-9,physical symptoms,sleep difficulties and resilience(p<0.01).GAD scores were also associated with sleep difficulties(p<0.01)and raising young children(p<0.05).MD scores were associated with sleep difficulties,job-dissatisfaction,and educational level(p<0.05).The limitations of the study include small sample size,usage of smartphone or email,potential under-reporting by stigma in the socio-cultural context and evolving nature of pandemic.We conclude that keeping careful watch for mental symptoms,stressors,sleep difficulties and other physical symptoms are important even for the individuals without previous mental illnesses during the pandemic era.Kye S.Kim Peter M.Kang He Sook N.Kim 2021International Journal of Mental Health Promotion2021,23,3:0
