H. D. Chope 《The Western journal of medicine》1959,91(4):189-192
The techniques and principles of epidemiology, so successfully utilized in the study and control of communicable diseases, should be applied to other mass phenomena in the community.The local health officer should apply them in his “diagnosis” of the sicknesses of his organized community.Epidemiological methods have been used to study mental diseases as well as chronic diseases, and an experiment in using epidemiological methods on the county level to study psychosocial disorders has been carried out.The impact of psychosocial episodes on somatic diseases is now generally accepted and well documented. Individual practitioners of medicine are becoming more interested in the significance of social tensions on the health of their patients.Public health physicians, specialists in preventive medicine, are the best equipped by training and experience to take the leadership in the application of epidemiological methods to sociomedical problems and are in a unique position to assist their colleagues in the private practice of medicine in providing modern helpful and meaningful health protection to their patients.Organized medicine might well become more cognizant of the sociological changes taking place in the nation as they relate to health and assume the responsibility for aggressive leadership in the anticipation of and the solution of these problems. 相似文献

Lethaia , a new international journal of palaeontology and stratigraphy, is introduced. Modern publishing in this field requires more consistent differentiation of the material into monographs and journal articles, and modern techniques allow us to adopt a strict journal style for reasoning articles, with all figures in the text. These pages serve as an example of Lethaia's main text, grades of headings, and arrangement of halftone illustrations. 相似文献

INTRODUCTION Man has always regarded nature as his Mother, the source of beauty, the symbol of eternity, the embodiment of truth, the master of all art and the basis of his material life. He regards landscapes as ideal places for studying, visiting, relaxation and the appreciation of Nature. 相似文献

东海表层沉积中的翼足类及其地质意义 总被引:1,自引:0,他引:1
对东海84个表层沉积中翼足类进行了定量分析,共获得7属15种,其中Limacinainflata在陆架外缘和上陆坡为优势种,Limacinatrochi formis,Creseisacicula和Creseis virgule在中外陆架最为丰富。根据翼足类的深度分布确定东海现代文石补偿深度在约600m水深处。以冲绳海槽北部柱状样B3GC为例,说明翼足类是研究地质时期古海洋学变化的重要证据。 相似文献

沙河街组介形虫化石群定量分析方法及其地质意义 总被引:2,自引:1,他引:2
本文通过对山东济阳坳陷沙河街组含介形虫化石岩心样品进行散样方法试验,表明水煮法、汽油法是第三纪地层微古分析行之有效的样品处理方法,利用这种方法可以获得大量的数据,从而可以进行介形虫等微体化石群的定量分析。文中对沙河街组介形虫化石群的一个组合和三个亚组合进行了定量分析。分析结果表明,较之以前定性描述,定量分析更能完整、准确地反映化石群面貌,并可进行种群结构、群落结构研究,从而为进行沙河街组沉积时期的 相似文献

山东东营凹陷早第三纪沙一段介形虫丰度的不均匀性及其地质意义 总被引:3,自引:0,他引:3
东营凹陷四个钻孔(2.下2-观18、滨297、牛101、樊101)沙河街组一段岩心样品介形虫化石丰度统计表明:1)不同的岩性介形虫化石丰度可以有很大不同;2)同一钻孔垂向上不同层段中介形虫化石丰度也显示出不均匀性;3)在岩心层面上,介形虫化石的分布有六种形式:密集分布、零星分布、簇状分布、条带状分布、虫穴充填、裂缝充填。除前两者外,均显示出层面上化石分布的不均匀性。造成上述化石丰度不均匀性的原因包括生态学和埋葬学两种因素。最后文中讨论了这种化石丰度不均匀性所反映的地质意义。 相似文献
