It is in the national interest to solve the public problem that arises as a result of the gaps in existing infrastructure in the country; Therefore, it is natural that the formulation of public investment projects is necessary to make viable, design and execute works aimed at solving such an important problem. But as detailed in the present investigation, the execution of such public works is subject to the effects of typical risks that translate into longer terms and costs, increasing the confusion of the population affected by such an important public problem. The research carried out allows us to verify that “The application of risk management in construction contracts within the framework of public policies has a direct impact on reducing bad practices in terms of deadlines and costs in the execution of works in the construction sector in Peru, year 2019”. Based on this verificat...

In Chile, the main issues affecting the quality of life of the population include air pollution, scarcity and contamination of water resources, degradation, loss, and pollution of soils, nuisance noise, solid waste management, and loss of biodiversity. In response to this situation, good environmental practices emerge in households, which can be characterized as simple and useful measures that individuals can adopt in their daily lives to reduce the negative environmental impact of their activities. In this context, the article presents the results of a qualitative research aimed at identifying and classifying the environmental practices carried out in households in Metropolitan Valparaíso, Chile. Methodologically, an exploratory-descriptive approach study was conducted, gathering information from 64 households through semi-structured interviews. The results show the implementation of g...

The problem of safe obstetrical care has special relevance in recent years due to the interest of health professionals in reducing adverse events and improving healthcare. However, this is pursued in complex, uncertain and variable scenarios and risks, where human behavior may increase the probability of error. We often have to make short term decisions when attending two patients simultaneously – mother and fetus-, and the mother expects a deferential treatment during pregnancy, delivery and the puerperium. These processes involve multiple activities and tasks, and failures may occur. Faced with the paradigm change of involving the patient in the care and decision making process, we have to provide them with the most complete evidence, to avoid contingencies and to obtain the best possible results.

The definition of the state has its origin in law, which in turn is linked to man. In this context, the state is understood as the subject or unit of the legal order in which social life takes place. This article discusses the role of the state in modern society through an analysis of the problems it must face in order to survive and prevail. The challenges that a state must face are many; however, the author emphasizes that the main problems are related to the nature of the state itself. The association of citizens in different political parties and, in particular, the formation of subversive groups that threaten the law have always posed a challenge to social stability. At this point, the author emphasizes that revolution is justified only when a state has placed particular interests above the common good. Other issues may arise from the relationship between church and state, which mus...

Los diferentes tratamientos de la demencia no han probado tener resultados clínicos que modifiquen el curso de la enfermedad o reduzcan su impacto en términos de discapacidad o mortalidad. Esta revisión señala que es factible evitar el desarrollo de la demencia a pesar que la edad sigue siendo un importante factor de riesgo no modificable. El control de factores modificables ampliamente reconocidos y ligados etiopatogénicamente pueden disminuir el número de casos de demencia. Las intervenciones multimodales enfocadas en el control de estos factores de riesgo aún tienen resultados inconsistentes. Se indica que deberían ser realizados nuevos ensayos además de aplicar el enfoque de medicina de precisión clínica que permita contar con evidencias que mejoren la toma de decisiones en salud pública para afrontar este problema.

Migration is a multidimensional phenomenon that, historically, has developed since the emergence of humanity, due to the movements of human groups for different causes or purposes. Nowadays, migratory flows stem from different economic, political and social aspects that are immersed in globalization; for example, capital mobility, job search, ethnic or religious differences, armed conflicts or poverty. These factors have become radicalized over the years to the point where the living conditions of people displaced voluntarily or involuntarily have been violated. Given this environment, spaces for dialogue have been consolidated at a global level and the presence of States such as Peru to evaluate the migration crisis, and reach agreements that allow the establishment of a regulatory framework on this matter at the international and national levels, respectively. Due to what has been expr...

As we know, elective cesarean section is a surgical procedure designed to reduce maternal, neonatal and perinatal morbidity and mortality, in situations that hinder vaginal delivery or that require an immediate termination of pregnancy (1). However, it is not free of complications. The same operative act and the effects of anesthesia can cause problems in the mother and in the child. In a 2016 systematic review evaluating maternal mortality attributed to anesthesia during caesarean section, it was found that 2.8% of maternal deaths, 3.5% of deaths due to obstetric complications and 13.8% of Total surgeries were attributed to the effects of anesthesia (2). On the other hand, it is known that a cesarean section increases the risk of death by six times when compared with vaginal delivery (3).

This research work starts with the question: What would be the reason why our compatriots choose to live in vulnerable areas, exposing their own life and that of their relatives? This question is relevant because it affects millions of compatriots (36% of the population, according to the Ministry of the Environment) and is applicable to any part of Peru. To answer the question an explanatory model is proposed, indicating variables of analysis, and their possible relationships, to make simulations, from the model. It is necessary to consider that the objective of the simulations is not to provide exact results, but to describe possible future behaviors, considering the actions that we take in the present. The proposed model considers a horizon of 50 years, and indicates that only if the problem is treated intensively the percentage of people in vulnerable areas could be reduced after a de...

Like other countries in the region, femicide—the gender-based murdering of women—has been incorporated into Peruvian law as a criminal offense. This inclusion is the result of the government and civil society organizations interest in producing policies aimed at reducing gender-based violence, and it has emerged as a result of a debate regarding «the increase in femicide» and the systematic appearance of media stories and official reports warning of an exponential growth. This article focuses upon the problem of femicide in Peru through a comparative approach. The aim is to account for the incidence of femicide in sociometric terms and demonstrate that this is not a phenomenon of exponential growth in epidemiological terms. This is achieved through the recognition of two issues: on the one hand, the way indicators are produced for criminal record figures and the ways these are meas...

The Zika virus is a mosquito-borne flavivirus that has emerged as a significant threat in the region of the Americas, especially for pregnant women. Recent outbreaks in Central and South America have been associated with an increase in the incidence of microcephaly and other central nervous system abnormalities in newborns. There is a causal link between Zika infection during pregnancy and microcephaly and other neurological disorders. The region faces a probable epidemic with potential consequences for pregnant women and newborns. The epidemiology of the Zika virus, its threat to pregnancy, clinical consequences and impact on public health are reviewed. A number of features of the mechanisms of infection and dissemination sustain preventive interventions, diagnosis and management of the disease. It is important to intensify its epidemiological surveillance, and to work on prevention and...

The research addresses the problem of violence against women. To do this, it defines genderbased violence in its various manifestations, details the evolution of international and national regulations on this matter and analyzes the official statistics provided by the competent state institutions. Later, it explains and sustains that the penal system does not resolve social conflicts, to later affirm and sustain that criminality is produced by the design of the social structure, and is learned in social interaction. Finally, it proposes the “government of crime” as an effective mechanism to reduce criminality against women to tolerable limits.

Se propone una nueva modalidad de entrega que comparamos con la actual. Ésta consiste en compartir recursos, los repartidores, entre tiendas con el fin de reducir la variabilidad de la demanda y optimizar su utilización. Se hace la hipótesis que esta nueva modalidad puede reducir los costos de contratación, reduciendo la cantidad de repartidores para lograr el mismo nivel de servicio que se tiene, utilizándolos más eficientemente. El costo total de la operación se resume en tres componentes: el de contratar, el cual es variable según la cantidad de repartidores; el costo esperado por la pérdida de las órdenes que se entregan fuera del tiempo establecido con el cliente, el cual disminuye con la cantidad de repartidores y el costo adicional por el traslado de los repartidores entre tiendas para cubrir la demanda necesitada, el cual incrementa según se compartan más los recursos...

La salud mental es un componente integral y esencial en el individuo porque le permite gozar de bienestar, lo faculta para afrontar el estrés natural del día a día, laborar productivamente y aportar a la sociedad. Sin embargo, en el Perú, solo el 20 % de las personas que padecen un trastorno de salud mental logran atenderse con un profesional especializado, esto debido a la oferta insuficiente de profesionales, la estigmatización social y los efectos de la pandemia por la COVID-19. En tal sentido, el uso de la tecnología existente se presenta como una alternativa eficiente para optimizar los recursos disponibles a fin de reducir las brechas de atención de salud mental en la población; a pesar de ello, no se aprovecha eficientemente. En la presente tesis, se hace uso de las siguientes metodologías ágiles: Metodología Design Thinking y Metodología Lean Startup para empatizar co...
