Enseñanza de la estadística: comparación de la efectividad del método tradicional y un nuevo método utilizando las Tic
Authors: Giraldo Colmenares Dignoria 
Published: December 2019

En la enseñanza tradicional, el proceso educativo gira en torno al docente, quien emplea como recursos básicos, la tiza, el tablero; la metodología de tra­bajo es explicativa, ilustrativa y demostrativa, se ejecuta por medio de la clase magistral teórica; el alumno es un receptor pasivo de información. La evalua­ción del aprendizaje, se hace a través de exámenes orales o escritos, la mayoría de las veces con preguntas subjetivas, no contextualizadas; los resultados son utilizados por el maestro para acreditar el nivel de competencias del alumno.
Con las nuevas tecnologías a nivel educativo, se implemento el sistema de for­mación por créditos o unidades de labor académica, en el cual los niños realizan actividades presenciales con sus docentes y trabajo autónomo, no presencial y personalizado.

Published: December 2019

Poverty is one of the social problems that the government can never completely solve. As a result, other, more significant social issues arise and cause social vulnerability, such as conflict and crime. As a province that is experiencing rapid growth in the last ten years, the West Sumatra find difficulty to overcome the number of poor people in several districts and cities. The research outcomes are the models and forms of social policy made by West Sumatra regencies and cities governments in improving the welfare of poor communities. It is also covering the constraints or obstacles to the implementation of social policy and the selection of welfare state models for the poor in some districts and municipalities of West Sumatra. This research is conducted qualitatively with a sociological approach that uses social perspective on searching and explaining social facts that happened to needy groups. Based on research conducted that the social policy model adopted by the government in responding to social problems in the districts and cities of West Sumatra reflects the welfare state model given to the poor. There is a strong relationship between the welfare state model and the form of social policy made by the government.
Un reto para Colombia: mejorar la utilización de medicamentos probadamente beneficiosos en la prevención secundaria cardiovascular
Authors: López-Jaramillo Patricio , Camacho Paul Anthony 
Published: December 2019

Las enfermedades cardiovasculares (ECV) causan 30% del total de las muertes en todo el mundo; de estas 80% sucede en los países en vía de desarrollo. El 1% de las personas en el mundo presenta un evento coronario agudo o cerebrovascular por año y la mitad de estos eventos se produce en individuos con enfermedad vascular preexistente. Los países de bajos y medianos ingresos presentan un incremento en la carga de las ECV y la mayoría no tiene programas concretos y bien definidos para su prevención.Se ha estimado que para el año 2020, habrá un aumento entre 120% y 137% en la incidencia de enfermedad coronaria en las mujeres y los hombres respectivamente, en los países en desarrollo. Este fenómeno se explica, entre otras razones, por la denominada transición epidemiológica, que se asocia con un notable aumento en la prevalencia de facto-res de riesgo como la obesidad, la hipertensión arterial, el tabaquismo, el consumo exagerado de alcohol, los cambios en los hábitos nutricionales y el sedentarismo. Estos factores están relacionados con la rápida urbanización que han sufrido los países de bajos y medianos ingresos.

Introduction: The pathophysiology of cerebral ischemia is essential for early diagnosis, neurologic recovery, the early onset of drug treatment and the prognosis of ischemic events. Experimental models of cerebral ischemiac an be used to evaluate the cellular response phenomena and possible neurological protection by drugs.Objective: To characterize the cellular changes in the neuronal population and astrocytic response by the effect of Dimethyl Sulfoxide (DMSO) on a model of ischemia caused by cerebral embolism.Methods: Twenty Wistar rats were divided into four groups (n= 5). The infarct was induced with α-bovinethrombin (40 NIH/U). The treated group received 90 mg (100 µL) of DMSO in saline (1:1 v/v) intraperitoneally for 5 days; ischemic controls received only NaCl (placebo) and two non-ischemic groups (simulated) received NaCl and DMSO respectively. We evaluated the neuronal (anti-NeuN) and astrocytic immune-reactivity (anti-GFAP). The results were analyzed by densitometry (NIH Image J-Fiji 1.45 software) and analysis of variance (ANOVA) with the Graph pad software (Prism 5).Results: Cerebral embolism induced reproducible and reliable lesions in the cortex and hippocampus (CA1). similar to those of focal models. DMSO did not reverse the loss of post-ischemia neuronal immune-reactivity, but prevented the morphological damage of neurons, and significantly reduced astrocytic hyperactivity in thesomato-sensory cortex and CA1 (P <0.001).Conclusions: The regulatory effect of DMSO on astrocyte hyperreactivity and neuronal-astroglial cytoarchitecture, gives it potential neuroprotective properties for the treatment of thromboembolic cerebral ischemiain the acute phase.

The effects on the consolidation process are analyzed for the final conclusions. The advantages of the method are briefly discussed, and some potential areas for scientific research are proposed.
CFD code-to-code benchmarking on simulation of fire and smoke propagation for nuclear applications

Published: December 2019

Abstract
The nuclear industry has seen an increased use of Computational Fluid Dynamics (CFD) technology as a high-fidelity tool for design-basis and beyond design-basis accident simulations. For fire hazards, detailed experimental investigation in a realistic environment is often impractical. Therefore, the use of an advanced 3D CFD modeling approach to predict smoke and fire propagation has risen, especially for nuclear power plant fire modeling applications. CFD simulations can include major contributing and mitigating mechanisms regarding the fire propagation and its consequences, in fine detail and under realistic geometry conditions. In addition, accurate simulations of unsteady 3D fire and smoke spread, in conjunction with evacuation analyses, can be used to establish effective emergency evacuation strategies. In the present study, the fire and smoke propagation in a main control room was modelled using Reynolds-Averaged Navier-Stokes Equation based twoequation turbulence models and a Large Eddy Simulation model implemented in a commercial CFD code, Siemens STAR-CCM+. The predictions from STAR-CCM+ were compared with those obtained in a previous study using the NIST Fire Dynamic Simulator (FDS) code. Although higher temperature was predicted at the fire source by STAR-CCM+, the current study predicted trends similar to the FDS results with some minor differences at the operator location. A follow-up study is currently underway to investigate the factors affecting the differences, including further assessment of codes against available benchmark experiments.
Mini-invasive methods of treatment of diabetic foot pain
Authors: Dmytriiev Dmytro , Lysak Yevhenii , Glazov Yevhenii , Geranin Stanislav , Zaletska Olesia 
Published: December 2019

Neuropathic pain occurs with diabetic polyneuropathy more often than with all polyneuropathies of another etiology. Because the cause of pain can rarely be cured, treatment is usually symptomatic. Neuropathic pain is usually poorly controlled by analgesics. Management of neuropathic pain is started with conservative pharmacotherapy before invasive pain management is applied. Although there are many drugs that can be used in patients with diabetic pain syndrome, pain syndrome can not be surely stoped with monotherapy. In addition, the patient may not tolerate the full therapeutic dose of the drug.
All this dictates the need for combination therapy. It is believed that regional anesthesia as an independent type of analgesia or a component of combined anesthesia is the method of choice for the elderly and senile patients. The main reasons for this choice, when comparing regional anesthesia with narcosis, are less stressful response of the organism, absence of depression of the central nervous system, stable reliable analgesia with complete blockade of nociceptive reflexes with the provision of adequate muscle relaxation, prevention of neurovegetative reactions, which ultimately helps to reduce the incidence of postoperative complications and mortality. Clinicians have accumulated considerable experience demonstrating the need for regional analgesia in the management of diabetic foot pain.
Ochrona praw dzieci w prawie polskim i międzynarodowym w kontekście ochrony ich zdrowia
Authors: Zdyb Marian 
Published: December 2019

Nie ulega wątpliwości, że najbardziej kluczowym i fundamentalnym prawem człowieka jest prawo do ochrony życia i zdrowia człowieka. Szczególnie ważne znaczenie ma odniesienie tegoż prawa do życia i zdrowia do dzieci. Mając na uwadze dziecko, podkreślić należy, że jest nim istota ludzka od momentu poczęcia (a więc także w fazie prenatalnej) aż do uzyskania pełnoletniości ( co do zasady jest to wiek 18 lat). Prawa te mają charakter pierwotny, co oznacza, że państwo ich nie nadaje, ma jednak obowiązek stworzyć warunki do ich optymalnej realizacji. Szereg praw w tej materii potwierdzone zostało w Konstytucji RP, w której zwraca się uwagę na wyjątkowe obowiązki państwa i każdego ochrony prawa do życia i zdrowia i zapewnienia optymalnych warunków w zakresie ich zabezpieczenia, w tym praw dziecka jako pacjenta. Problem ten w szerokim zakresie został uregulowany w szeregu aktach prawa międzynarodowego, gdzie na szczególne podkreślenie zasługuje Konwencja o ochronie praw dziecka. Podstawowe jednak zadanie ciąży w tym zakresie na ustawodawcy krajowym. Mimo, że aktualnie w Polsce problematyka ta regulowana była w bardzo wielu ustawach, dotyczących ochrony zdrowia (a przez to życia) przyjąć należy, że mamy aktualnie do czynienia z sytuacją wysoce niezadawalającą. Stąd też od ustawodawcy wymagać należy wytężonej pracy w kierunku zmiany takiej sytuacji. Jest to niewątpliwie w interesie państwa i obywateli.

The results of petrological-geochemical and isotope-geochemical studies of the Late Pleistocene-Holocene lavas of the Kazbek Neovolcanic Center, one of the largest centers of youngest magmatism in the Greater Caucasus, are presented.
It has been established that the volcanic rocks of the Kazbek center arise a continuous compositional series basaltic (trachy-)andesites(trachy-)andesitesdacites with a predominance of calc-alkaline intermediate and moderately-acid lavas. The obtained results indicate that the processes of fractional crystallization and mixing of melts had a leading role in the petrogenesis of the rocks. The crustal assimilation was of limited importance; its influence is noticeable only in the rocks of the earliest and late pulses of magmatic activity within the Kazbek center. The common crustal lithologies participated in the assimilation were presented by metamorphosed Jurassic sediments (mainly shales and sandstones), forming the foot of the Kazbek center, and Mesozoic mafic metamorphosed volcanites very rarely. The specific features of AFC processes during the development of the studied magmatic system (including the presence of noticeable amount of water in the melt, the leading role of Amp in the cumulus and the absence of Pl fractionation) led to the appearance of dacitic lavas with geochemical signs of adakites as an evolutional end-member.
The volcanic rocks of the Kazbek center are derived from trachybasalt magmas, the source of which was presented by the mantle reservoir of OIB-type. Recent and previously published results of studies of the Neogene-Quaternary magmatism manifested within the Greater Caucasus show that the main petrological and geochemical characteristics of this regional mantle reservoir remained constant from the end of the Miocene to the present time.

Published: December 2019

Recebido: 06/04/2019 Aprovado: 27/05/2019Publicado: 10/07/2019O presente artigo busca compreender como o sertão, tema recorrente em importantes obras literárias brasileiras, a exemplo dos clássicos “Os Sertões”, “Vidas secas”, e “Grande sertão: veredas”, é representado na composição dos poemas de Jessier Quirino, cuja tessitura dá-se, diversas vezes, através de uma “linguagem matuta” que se mistura à forte presença de neologismos e aos denominados “espaços da saudade”. Tais espaços ora se dão como referências geográficas, elaboração de cenários interioranos, menções à indumentária e à culinária nordestinas, ora se dão como o próprio espaço do poema, da leitura e escuta dos textos, diversas vezes voltados para um rememorar ou (re)inventar de determinados passados. Interessa-nos compreender como determinadas imagens representadas no poema Zé Qualquer e Chica Boa, contribuem para construir identidades para personagens sertanejas e como contribui para reforçar uma imagem estereotipada daregião. Palavras-chave: Espaços da saudade, Jessier Quirino, representação, memória, sertão.
