In this work we slwly linear polynomial operators preserving some consecutive i-convexities and leaving in-verant the polynomtals up to a certain degree. First we study the existence of an incompatibility between the conservation of cenain i-cotivexities and the invariance of a space of polynomials. Interpolation properties are obtained and a theorem by Berens and DcVore about the Bernstein's operator ts extended. Finally, from these results a genera'ized Bernstein's operator is obtained.

This work was aimed at assessing one of the examinations applied to the students enrolled in courses of Biochemistry and Molecular Biology at the School of Medicine, UNAM. We analyzed a f＇mal examination in this subject. The test consisted of 80 multiple choice questions. The database was exported to Excel and then to the SPSS 16 statistical software for statistical analyses. The following techniques were used：（1） dificulty index （Pi）, （2） discrimination index （Di）, （3） discrimination coefficient （rpbis）, and （4） Cronbach＇s alpha. Those questions that complied with 3 of the 4 mentioned techniques were considered acceptable; of the 80 questions, only 25 were accepted corresponding to 31%. The topic with the largest number of accepted questions was Water and pH （75%）, and the topics without accepted questions were Bioenergetics and Hormones （0%）. It is recommended that the faculty members that elaborate multiple choice examinations must know the subject, and should have a formation in didactics and educational methodology.

The actual challenge in health is to manage patients with chronic diseases from a holistic approach where technology around the patient and at the city enhances their wellness. This paper deepens in the relations between health, devices, and models of technological cities and how these can be modeled to provide a more cost efficient solution while less invasive and more natural to the end users. In light of this, usable and accessible software and a wide range of devices, ranging from PC, smartphone, tablet and SmartTV have been tested. This manuscript will give good comprehension on how technology and disease management care models interact with the patient.

自1991年起对玻利维亚的查卡尔塔亚冰川(16°S,雷亚尔山)和1995年起对厄瓜多尔的安蒂扎纳15号冰川(0°,厄瓜多尔)的质量平衡作了连续监测。在冰川消融区,按一个月尺度测量了质量平衡,提供了有关两种不同热带环境中季节性变化模式的有意义的详细数据。这两个地区最近40年来都有关于冰后退的断断续续的报道。这些资料指出,这10年来冰川退缩明显加速了;消融速率已比前几十年高3～4倍。以前在秘鲁北部测量3条冰川的变动,使我们可以假定:安第斯山脉热带山段冰川退却的速率在20世纪70年代增高了。小规模冰川(<1km)的现状特别令人担忧,象查卡尔塔亚等许多冰川将在今后10年内消失。已经收集的资料证明,在ENSO(厄尔尼诺南方涛动)变暖期消融作用显著增强,而在变冷期(拉尼娜)减弱。自20世纪70年代晚期以来,变暖事件变得更频繁、更强烈了。可以假定,它们已对安第斯山脉中部现代冰川退缩起了显著作用,还有全球气候变暖的影响。
