  • A number of studies have evidenced the effect of modifiable lifestyle factors such as diet, breastfeeding and nutritional status on breast cancer risk. However, none have addressed the missing data problem in nutritional epidemiologic research in South America. Missing data is a frequent problem in breast cancer studies and epidemiological settings in general. Estimates of effect obtained from these studies may be biased, if no appropriate method for handling missing data is applied. We performed Multiple Imputation for missing values on covariates in a breast cancer case-control study of $C{\acute{o}}rdoba$ (Argentina) to optimize risk estimates. Data was obtained from a breast cancer case control study from 2008 to 2015 (318 cases, 526 controls). Complete case analysis and multiple imputation using chained equations were the methods applied to estimate the effects of a Traditional dietary pattern and other recognized factors associated with breast cancer. Physical activity and socioeconomic status were imputed. Logistic regression models were performed. When complete case analysis was performed only 31% of women were considered. Although a positive association of Traditional dietary pattern and breast cancer was observed from both approaches (complete case analysis OR=1.3, 95%CI=1.0-1.7; multiple imputation OR=1.4, 95%CI=1.2-1.7), effects of other covariates, like BMI and breastfeeding, were only identified when multiple imputation was considered. A Traditional dietary pattern, BMI and breastfeeding are associated with the occurrence of breast cancer in this Argentinean population when multiple imputation is appropriately performed. Multiple Imputation is suggested in Latin America's epidemiologic studies to optimize effect estimates in the future.

  • This article is a study of Karl Marx's manifesto and the reform in donghak for the modality and their symbolism. As a text, Karl Marx and Friedrich Engels' declaration on the Communist Alliance and the reform program of the peasant Donghak were choose. This Declaration and the Reformation are the works of philosophical practice discourse of the 1800s in this article, which unfolds paradigmatically, deriving its common symbolic meaning in the semiotic sense, and evolving ideologically towards a democracy free of property. In the end, these two historical incident which are published in the contemporary breath, constitute an accusation against a nonhuman policy of surveillance and punishment. Twice a day, the space of the church is transformed into a factory, the act of dividing into two categories by capitalist and work and divorcing by accident is embodied as a social ethic. It is against the phenomenon that the structure of which no man exists is no longer institutionalized. The revolutionary movement aimed at breaking the framework of this hunt manifests itself in the two manifestos mentioned above, and Karl Marx completes the culmination of the utopia that must be achieved through the Declaration of the Communist Alliance by placing his being in the position of "eternal refugee". By choosing to die in his freedom developed during Jeon Bong-joon's trial, he also completes the people's spirit of revolution. In the case of simultaneous exploitation in East and West, the form of oppression is the withdrawal of capital from domination and power, and a new alternative to this is the philosophical context that allows the establishment of a new paradigm with "man is the greatest capital".
