Educar para la sociedad de la información y de la comunicación: una perspectiva latinoamericana
Authors: Hopenhayn Martín 
Published: December 2020

Como ya constataban la CEPAL y UNESCO en 1992, «la transformación educativa pasa a ser un factor fundamental para desarrollar la capacidad de innovación y la creatividad, a la vez que la integración y la solidaridad».
Ese papel de la educación parece haberse consolidado a lo largo de estos 10 años a partir de su capacidad para: facilitar el acceso a trabajos «inteligentes» y a redes de conocimiento; reducir las desigualdades; aportar elementos críticos para interpretar la realidad incorporando el componente multicultural y construir ciudadanía en contextos democráticos.
En este sentido han avanzado las reformas educativas que se ejecutaron en casi todos los países de América Latina y que, sin embargo, no consiguieron eliminar algunos de los factores que determinan un alto grado de estratificación y consecuentemente de inequidad, al interior de sus sistemas educativos. Como no podía ser de otra manera, las desigualdades se extienden, entre otras cuestiones, al acceso y manejo de las redes informáticas y de los medios audiovisuales.
Este es el panorama que –profusamente documentado– presenta M. Hopenhayn como punto de partida para describir las condiciones necesarias y deseables para educar para la sociedad de la información y la comunicación desde una perspectiva latinoamericana.
No todo es negativo en este planteamiento. Los gobiernos latinoamericanos están haciendo grandes esfuerzos para alcanzar niveles adecuados de calidad y equidad en la educación y, como parte de ese esfuerzo, se han puesto en práctica numerosos proyectos de dotación de equipamiento tecnológico y conectividad a un número cada vez más grande de establecimientos educativos. No debe olvidarse que «es en las escuelas donde el acceso puede democratizarse».
Sobre estos dos pilares, calidad educativa y acceso al intercambio comunicacional, se intenta promover la incorporación masiva y sostenida de los países de la región a la sociedad del conocimiento.
Otro dato esperanzador es la velocidad de difusión del acceso a Internet en América Latina, superior a la de cualquier otra región, y la relación entre acceso y equipamiento, cuya proporción está optimizada respecto de la de otras áreas.
Para complementar los aspectos tecnológicos será necesario que los sistemas educativos tengan en cuenta que la introducción de las TIC es un proceso lento, que se requiere articular su difusión con las necesidades pedagógicas de los profesores; que debe respetarse la heterogeneidad de los distintos actores y entornos del proceso educativo y que deben articularse con otros aspectos de las reformas educativas.
Educación para la democracia en las escuelas: un desafío pendiente
Authors: Prieto Marcia 
Published: December 2020

La crisis valorativa que sufre la sociedad actual y sus efectos se han proyectado en todos los ámbitos y muy especialmente en la cultura escolar, la que informada por una racionalidad instrumental, está mas preocupada de cautelar la consecución de fines y objetivos institucionales que de formar en valores y desarrollar personas integralmente. Se podría decir que la escuela no ha tomado conciencia respecto de la responsabilidad pública que le cabe en la construcción de una comunidad en la que los estudiantes se eduquen a partir del desarrollo y práctica del intercambio y negociación de creencias y valores, la construcción de relaciones basadas en la cooperación, el apoyo mutuo, la libre expresión de las ideas y la tolerancia, actitudes y valores que los prepararán efectivamente para la convivencia social democrática.
A formação continuada em serviço
Authors: Casadei Salles Fernando 
Published: December 2020

O tema escolhido deste trábalo é o da formação continuada em serviço dos professores.
O objetivo em articular em um único processo as dimensões da prática docente com a formação continuada dos professores em serviço. Partindo da crítica, no momento da sua proposição inicial, de que a forma mais freqüente de como as propostas de formação continuada se desenvolviam, através de cursos de suplência e ou de atualização dos conteúdos de ensino, se mostravam pouco eficientes para a melhoria da prática docente
A idéia era de que os docentes, ao refletirem sobre as suas próprias práticas, se apropriassem dos canais de diálogo entre a realidade vivida e interpretada, ampliando suas respectivas possibilidades de compreensão objetiva dos mecanismos e conhecimentos sobre a identidade profissional docente.
Violencia de género en la escuela: Sus efectos en la identidad,en la autoestima y en el proyecto de vids
Authors: Flores Bernal Raquel 
Published: December 2020

A medida que se resuelven las dificultades de integración de las mujeres en la educación, el problema pasa a ser, no el de «cuántas mujeres estudian, sino el de cuál es la calidad de la educación y cuál el ambiente de estudio». Los obstáculos que encuentran las mujeres en el sistema educativo, más allá de la posibilidad de acceder o no a éste, son: los estereotipos presentes en el material educativo, y la segregación en la orientación vocacional (la cual afecta también a la participación de las mujeres en el progreso científico-tecnológico y en la educación técnica).
Si bien existen escasas diferencias formales en los programas educativos de hombres y de mujeres, los mecanismos de discriminación se relacionan con el contenido sexista de los textos escolares, con los materiales didácticos, y con la relación del profesorado con sus alumnas, lo que constituye un currículo oculto que reproduce roles y concepciones discri-minatorias de la mujer.
Sólo un concepto de igualdad construido desde el reconocimiento de la diferencia individual y con independencia del género, permitirá el desarrollo de las potencialidades y la expresión de la riqueza propia de los seres humanos, sin limitaciones derivadas de su sexo.

Authors: Самченко А.Н. , Пивоваров А.А. , Швырев А.Н. , Ярощук И.О. 
Published: December 2020

В статье приводятся результаты экспериментальных исследований распространения низкочастотных акустических сигналов (33 Гц) на побережье залива Петра Великого Японского моря. Источник акустических сигналов опускался с борта маломерного судна в воду, а приемные системы были у береговой черты в воде и на суше. За счет использования трехкомпонентных виброметров стало возможно разделить принятые сигналы на различные типы волн (продольные, поперечные и поверхностные). Получены предварительные результаты расчета скоростных характеристик приходов различного типа волн на виброметры.
The article presents the results of experimental studies on the propagation of low-frequency acoustic signals (33 Hz) on the coast of Peter the Great Bay of the Sea of Japan. The source of acoustic signals descended from the board of a small boat into the water, and the receiving systems were at the coastline in water and on land. Through the use of three component vibrometers, it has become possible to divide the received signals into various types of waves (longitudinal, transverse and surface waves). The preliminary results of calculating the speed characteristics of the arrival of various types of waves on vibrometers are obtained.

Authors: Malik Abdul , Mohkumuddin Syed , Rahim Humaira , Hanif Shamima 
Published: December 2020

Background: Proton pump inhibitors (PPIs) are in routine widely prescribed to hemodialysis patients. Recent studies have reported the association of PPIs use with hypomagnesemia in patients with long term hemodialysis. This study aims to determine the frequency of hypomagnesemia in patients of hemodialysis taking proton pump inhibitors.
Patients and methods: This cross-sectional study was conducted in the Department of Nephrology of Sandman Provincial Hospital Quetta from 01-6-2019 till 01-9-2019. A total of 120 patients (52 PPI users and 68 non-PPI users) who were on HD for more than 06 months were included. Data regarding age, gender, duration of hemodialysis and taking PPIs were collected. Determination of serum magnesium was made by taking 3 different samples at 2 weeks’ interval and the mean value of serum magnesium was calculated. Serum Mg2+ levels <2.0 mg/dL was taken as hypomagnesemia. A Chi-square test was applied to determine the association of PPI use with hypomagnesemia.
Results: Demographic variables such as age and gender were not significantly different between the groups. There was female dominance in both groups (73% in PPI groups and 66.1% in the non-PPI group (p-value 0.65). The mean duration of dialysis was 45.3±13.8 months in PPI users versus 48.9±12.9 months in non-PPI users (p-value 0.14). There was a significantly higher frequency of hypomagnesemia in PPI users; 36 (69.3%) versus 27 (39.7%) in non-PPI users (p-value 0.001).
Conclusion: The use of PPI is associated with a significant reduction in serum magnesium levels. So serum magnesium levels should be advised as routine monitoring in patients of hemodialysis taking PPIs.

Published: December 2020

Background: Ischemic heart disease (IHD) is one of the leading causes of mortality in Pakistan. With advancement in research, multiple causes have contributed in development of web of causation of this public health issue. The objective of this study was to assess gender differences in risk factors associated with ischemic heart disease in patients presenting at the biggest cardiology hospital of Lahore.
Patients and methods: A comparative cross-sectional study was carried out in Punjab Institute of Cardiology, Lahore from January to August, 2018 on a sample of 296 diagnosed patients of IHD, through non-probability consecutive sampling technique. Data was collected on pretested questionnaire. The data was analyzed using SPSS version 22. Chi-Square test of significance was applied and a p-value ≤0.05 was considered statistically significant.
Results: The mean age of participants was 45±12 years with predominance of male patients (71.3%). Frequency of risk factors for IHD included increase body mass index (83.8%), hypertension (61%), insufficient physical activity (43%), diabetes (38.5%) and smoking (23%). Increase serum cholesterol was reported in 95% and triglycerides in 99% of the participants. Gender difference was significant with females residing in urban population (p=0.054) and exercise routine (p=0.034). Males showed high tendency of IHD with smoking pattern (p<0.001) contrary to presence of diabetes in females (p=0.05), hypertension (p=0.054), BMI (p=0.0379) and stressful event in life (p=0.002). Males showed regular intake of medicines (p =0.045) after diagnosis as compared to female population.
Conclusion: There is more frequency of ischemic heart disease in males as compared to females. Significant association was observed with residence in urban area, presence of diabetes, hypertension, high BMI and stressful event in life in occurrence of ischemic heart disease in female population.
Posterior and lateral ponticles of atlas: An osteological study at Fatima Jinnah Medical University, Lahore
Authors: Munawar Saira , Jafri Farhana , Qureshi Ahmad Farzad , Fatima Darab , Zahid Aliya 
Published: December 2020

Background: Among the cervical vertebrae, atlas is known to have many variations, posterior ponticle being the commonest. It may completely or incompletely covers the groove of vertebral artery leading to ischemia of posterior circulation. Therefore, vertebral artery is at greater risk of injury during neurological and spinal surgeries. Prevalence of posterior ponticles varies widely among different populations, for instance in Turkish population it was 10.8%, in American 22.1%, Kenyan 14.7%, Brazilian and Indian 16.7%. The prevalence of lateral ponticle in Kenyan population was reported to be 3.9% and in Indians it was 2%. However, the data regarding the prevalence of these ponticles is largely lacking in Pakistan. Therefore, this research was designed to determine the prevalence of posterior and lateral ponticle in atlas vertebrae of Pakistani population.
Materials and methods: A total of 47 human atlas vertebrae of unknown age and gender from bone bank of Department of Anatomy Fatima Jinnah Medical University, Lahore were studied for the presence of complete and incomplete posterior and lateral ponticles. The bones studied were completely intact and did not have any pathology.
Results: Total incidence of ponticles was 38 % in this study, of which 36% were posterior ponticles and 2% were lateral ponticles. Bilateral incomplete posterior ponticles/were found in 8 (17%) atlas vertebrae whereas bilateral complete posterior ponticles/foramen arcuale were found in only 1 (2%) atlas vertebrae. Unilateral incomplete posterior ponticle was identified on right side in 5 (11%) and left side in 2 (4%) atlas vertebrae. Unilateral complete posterior ponticle was found in only 1 (2%) atlas on the left side whereas no such finding was identified on right side in any vertebra. Unilateral complete lateral ponticle was found in only 1 (2%) atlas on the right side but not on left side. No bilateral complete lateral ponticle and incomplete unilateral or bilateral lateral ponticles were identified in this study.
Conclusion: Presence of posterior and lateral ponticles pose a risk of vertebrobasilar vascular insufficiency and may cause variety of symptoms. Vertebral artery may be at risk during neurosurgical procedures when having a foramen arculae and may give a false impression of much wider posterior arch of atlas. Knowing the prevalence of this can help neurosurgeons, general surgeons, radiologists, and chiropractors in management of the patients.
Use of non-contrast computed tomography determined urinary stone fragility in predicting the outcome of extracorporeal shockwave lithotripsy treatment: a single-center study
Authors: Hameed Athar , Gondal Khazir Hayyat 
Published: December 2020

Background: Renal stones represent a common urological pathology where standard treatment advised is ESWL in current practice. However, NCCT based determination of stone fragility may help to predict the outcome of ESWL treatment, hence optimizing its clinical use. Therefore, this study evaluated the role of NCCT determined urinary stone fragility in predicting the outcome of ESWL treatment in local clinical settings.
Patients and methods: One hundred patients with single renal calculus of 0.6-2 cm in size were included. NCCT based determination of stone fragility in HU units was done for all patients. Patients were then subjected to ESWL, with a maximum of 3000 shock waves given per ESWL session. Plain film and/or ultrasonography was used to monitor ESWL treatment progress with a final NCCT evaluation at 12 weeks to determine the clearance of the calculi for each patient. Association of NCCT based stone fragility and outcome of ESWL was statistically analyzed using Fisher exact test.
Results: The mean age of the patients was 37.7 ± 10.9 years with 54% being male. Decreasing stone fragility on NCCT (high = <500HU, moderate = 500-1000HU, and high = 1000HU) required more number and intensity of ESWL sessions (1-2 visits and 3000-6000 shock waves for high stone fragility group, 3-5 visits and 7000-18000 shock waves for the moderate group, and 6 visits and >18000 shock waves for low fragility group, respectively) necessary for clearance of urinary stones (p<0.001). In 98% of patients, the clearance of urinary stones was excellent.
Conclusion: Renal stone patients with NCCT determined high and moderate stone fragility show an optimal response after ESWL treatment, whereas, for low fragility renal stones attenuative treatment like percutaneous nephrolithotomy and/or ureteroscopy should be considered instead of ESWL. This approach can enable patient stratification before ESWL therapy ensuring better clinical management of the renal stone disease.

Published: December 2020

Аnnotation
Purpose. To increase the efficiency of technological processes of grain harvesting by large-scale agricultural producers due to the rational use of combine harvesters available on the farm.
Methods. In the course of the research the methods of system analysis and synthesis, induction and deduction, system-factor and system-event approaches, graphic method were used.
Results. Characteristic events that occur during the harvesting of grain crops, both within a single production unit and the entire agricultural producer are identified.
A method for predicting time intervals of use and downtime of combine harvesters of production units has been developed.
The roadmap of substantiation the rational seasonal scenario of the use of grain harvesters of large-scale agricultural producers is developed, which allows estimating the efficiency of each of the scenarios of multivariate placement of grain harvesters on fields taking into account influence of natural production and agrometeorological factors on the efficiency of technological cultures.
Conclusions
1.	Known scientific and methodological approaches to optimization of machine used in agriculture do not take into account the risks of losses of crops due to late harvesting, as well as seasonal natural and agrometeorological conditions of each production unit of the farmer, which requires a new approach to the rational use of rational seasonal combines of large agricultural producers.
2.	The developed new approach to the substantiation of the rational seasonal scenario of the use of combined harvesters of large-scale agricultural producers allows taking into account the costs of harvesting of grain and the cost of the lost crop because of the lateness of harvesting at optimum variants of attraction of additional free combine harvesters. provides more profit.
3.	The practical application of the developed road map will allow large-scale agricultural producers to use combine harvesters more efficiently and reduce harvesting costs.
Keywords: combine harvesters, use, production divisions, risk, seasonal scenario, large-scale agricultural producers.
Unfolding Cubes: Nets, Packings, Partitions, Chords
Authors: DeSplinter Kristin , Devadoss Satyan , Readyhough Jordan , Wimberly Bryce 
Published: December 2020

We show that every ridge unfolding of an $n$-cube is without self-overlap, yielding a valid net. The results are obtained by developing machinery that translates cube unfolding into combinatorial frameworks. Moreover, the geometry of the bounding boxes of these cube nets are classified using integer partitions, as well as the combinatorics of path unfoldings seen through the lens of chord diagrams.
