Authors: Páez - Amaya Darby , Català - Castro Frederic , Molina - Prado Martha Lucia , Montes-Usategui Mario , Arias - Hernández Néstor Alonso 
Published: April 2021

Optical tweezers use a highly-focused laser beam to capture and manipulate micro- and nanometric objects. These have been demonstrated to be a promising devices for state-of-the-art research in several fields, such as microbiology and biophysics. The prediction of the optical forces that are present in this phenomenon is a current problem in continuous evolution. Additionally, the recent use of vortex beams with exotic properties as the orbital angular momentum, with advantages as the rotational manipulation of the captured microparticles and reduction of the optical damage in biological samples (Opticution), makes the problem even more complex. Mathematical expressions in the Rayleigh and Mie regimes for the radiation force on a dielectric sphere captured by TEM00 and TEM*01 mode beams are presented. Theoretical results are then compared with experimental measurements obtained with a direct force measurement device based on light-momentum detection.

Published: April 2021

In this paper, we show an Adaptive Noise Canceller (ANC) that estimate an original audio a signal measured with noise. Adaptive system is implemented using a Recursive Least Squares filter (RLS). Its design parameters consider the filter order, forgetting factor and initial conditions to obtain optimal coefficients through iterations. A medium square error (MSE) around to 10-6 is reached, and with this it makes possible a low-cost implementation.

El presente artículo de investigación tiene como objetivo realizar un análisis del régimen simple de tributación en Colombia, en este se busca identificar las ventajas y desventajas que produce la implementación de este nuevo tributo para los distintos contribuyentes, para realizar dicho estudio se utilizó una metodología con un diseño documental, de tipo descripción, ya que se hizo una revisión de la bibliografía relacionada con el tema objeto de estudio, objetivos de libros, revistas electrónicas y repositorios de reconocido prestigio. El desarrollo de esta investigación es importante ya que se toma en consideración un tema de gran importancia en el ámbito tributario como es el Régimen Simple de Tributación que dará un aporte a todas las personas que tengan o no la intención de acogerse a este nuevo régimen. Dentro de los resultados se puede evidencias que con la aplicación del mencionado régimen se busca minimizar las diferentes cargas tributarias a las cuales están sometidas las empresas, sintetizando en un solo formulario varios tipos de impuestos, no obstante, este sistema por lo reciente tiene una serie de vacíos, lo cual no termina de convencer a los contribuyentes debido a que la base gravable es considerada simplemente con los ingresos ordinarios y extraordinarios. Como conclusión, se puede decir que este tipo de sistema de tributación es considerado no como viable por algunos contribuyentes, ya que no son suficiente los beneficios que ofrece para se afecte en forma positiva el pago de impuestos a ser cancelado por parte de los contribuyentes.

Point of Care Ultrasound First: An Opportunity to Improve Efficiency for Uncomplicated Pregnancy in the Emergency Department
Authors: Urquhart Sara , Stevens Kendall , Barnes Mariah , Flannigan Matthew 
Published: April 2021

Introduction: Research suggests emergency providers using point-of-care ultrasound (POCUS) to confirm an uncomplicated intrauterine pregnancy (IUP) can decrease emergency department (ED) length of stay (LOS) compared to a radiology department ultrasound (RADUS). The objective of this study was to compare the time to diagnosis and LOS between POCUS and RADUS patients. Methods: This was a retrospective study at one urban medical center. A standardized tool was used to abstract data from a random sample of pregnant patients diagnosed with uncomplicated IUP between January 2016 and December 2017 at a single tertiary care medical center. Microsoft Excel 2010 software was used to measure time intervals, prepare descriptive statistics, and perform Mann-Whitney U tests to compare differences. Results: A random sample of 836 (36%) of the 2,346 emergency department patients diagnosed with an IUP between 8-20 weeks’ gestation during the study period was evaluated for inclusion. Three hundred sixty-six met inclusion criteria and were included in the final analysis. Patients were divided into 2 groups based on which type of ultrasound scan they received first: POCUS (n=165) and RADUS (n=201). Patients who received POCUS were found to have an IUP identified in an average of 48 minutes (95% CI, 43 to 53), while the RADUS group’s mean time to diagnosis was 120 minutes (95% CI 113 to 127) with a difference of 72 minutes (95% CI, 63 to 80; p<0.001). The mean LOS for patients who received POCUS was 132 minutes (95% CI, 122 to 142), while that of the RADUS group was 177 minutes (95% CI 170 to 184) with a difference of 45 minutes (95% CI 32 to 56; p<0.001). The study is limited by its single-center, retrospective design and by lack of blinding of data abstractors. Conclusion: Pregnant emergency department patients diagnosed with an uncomplicated IUP between 8-weeks and 20-weeks’ gestation had statistically significant reduction in time to diagnosis and disposition from the ED if assessed with POCUS as compared to RADUS.
UKRAINE AND UKRAINIANS IN THE POLISH SOCIO-POLITICAL DISCOURSE OF THE FIRST THIRD OF THE TWENTIETH CENTURY: THE UKRAINIAN PERSPECTIVE
Authors: Futala Vasyl 
Published: April 2021

Summary. The purpose of the study is to show the achievements of Ukrainian historiography in studying the attitude of Polish politics in the early twentieth century and the interwar period to the Ukrainian question, to personify the scientific achievements of Ukrainian scientists, to predict the prospects for further scientific research. Research methodology is based on the principles of historicism, systemicity, and objectivity. In solving specific problems, methods of historiographical analysis and synthesis were applied. The scientific novelty is that on the basis of a wide range of historiographical sources created by Ukrainian researchers, the process of accumulation and dissemination in time of historical knowledge about the essence of national programs of Polish political circles of the first third of the twentieth century and ways to solve the Ukrainian question. Conclusions. The analyzed problem began to be studied at the scientific level in 1960–80’s. If the representatives of the Ukrainian diaspora only outlined its contours, the historians of Soviet Ukraine (referring primarily to Yu. Slyvka) made an attempt of a professional approach to the subject of research. Modern Ukrainian researchers, applying the latest research practices and Ukraine-centric approach, have made significant progress in the study of the topic. Through the efforts of L. Zashkilnyak, Y. Mykhalsky, V. Repryntsev, M. Zelinsky, Y. Vyalova, V. Komar, Y. Kramar, O. Yurchuk, M. Kucherepa and others, there has been an increase in scientific historical knowledge about the essence of national programs of the main Polish forces politicum in the early twentieth century and in the 1920s and 1930s, in particular, their attitude to the Ukrainian question. It is proved that two concepts concerning Ukrainians were leading – assimilation of national and state. Supporters of the first were representatives of the Polish National Democracy, and the second – supporters of J. Pilsudski. Attempts by Polish Ukrainophiles to impose the idea of territorial autonomy on Ukrainians in Galicia have failed. Theorists of Polish conservatives substantiated the eternal affiliation of "peripheral territories" to the Polish state, and therefore considered the Ukrainian question exclusively as a domestic political problem of a local nature. Among the government programs developed for certain regions of Poland, the most famous is the "Volyn program" of Governor G. Yuzewski.
Despite the great achievements in studying the positions of Polish political groups on the Ukrainian issue, there is a need for in-depth study of the ideology and practice of the centre-left and far-left movements. It is necessary to continue consideration of the principles of national policy of small Polish political parties, groups and blocs of liberal and conservative orientations. In addition, this scientific problem has the prospect of research through the prism of biography.
THE WAY TO UNITY: THE IDEA TO CREATE THE WORLD CONGRESS OF FREE UKRAINIANS
Authors: Vakhnianyn Anna 
Published: April 2021

Summary. The history of the Ukrainian diaspora/emigrants makes up an integral part of the Ukrainian history. The article traces the path of foreign Ukrainians to unification in order to defend the interests of the entire Ukrainian people. The successful Jewish experience may serve as the vivid example. The latter lived scattered for ages, but united and established World Jewish Congress in 1936, being able to declare the State of Israel in 1948. The purpose of our study is to trace the origins of the idea to consolidate the Ukrainian emigrants and to establish the only coordinative institution for the whole Ukrainian nation from all over the world in the 1920s, its evolution and the practical measures for its implementation. The successful experience of the Ukrainian diaspora can serve as a model for the modern Ukrainians, while the analysis of the mistakes of the latter can help to avoid them at the contemporary stage of state formation. Methodology. The methods to solve the aforementioned problem are the following: 1) the method of historical comparison of the Ukrainian and Jewish experience of consolidation; 2) historiographical analysis and synthesis; 3) inductive and deductive reasoning. The scientific novelty of our research is in the comprehensive step-by-step study of the World Congress of Free Ukrainians. Conclusions. The powerful centers of the Ukrainian political emigration appeared in the 1920s. They aimed to restore Ukraine’s unity and independence. However, there was disagreement among them, given the fact that they struggled for power in 1917–1920. S. Petliura was one of the first competent political leaders, who realized the necessity of consolidation. His associates A. Shulgin and V. Prykhodko made the first attempts to organize the World Ukrainian Congress in the 1930s. The idea was supported in Galicia and in the USA, though it wasn’t implemented. The same process may be noticed in the Jewish diaspora at the same time; however, they summoned the World Jewish Congress in 1936 and declared their own state. Because the Ukrainian politician leaders failed to create a single political center, the Soviet diplomats became the legitimate representatives of Ukrainians during and after the World War II. The establishment of the Pan-American Ukrainian Conference (PAUC) in 1947 is thought to be the pre-condition for summoning the World Congress of Free Ukrainians, as it was one of its key tasks. A. Melnyk was one of the most active lobbyists of the Ukrainian unity. He also introduced the idea of the organization superstructure. PAUC made a few attempts to summon the congress in the 50s – 60s of the 20th century, but none of these were successful. Consequently, the Ukrainian emigrants were disappointed with its PAUC’s ability to accomplish the task successfully. Despite this fact, in January 1967 PAUC published/promulgated the manifesto on summoning the World Congress of Free Ukrainians launched the active propaganda campaign, and the long way of the Ukrainian nation to consolidation met with success in November.
Partnership Commitment During a Global Pandemic
Authors: Frimoth Margaret R. 
Published: April 2021

Riane Eisler challenges us to identify and embrace partnership relationships in every aspect of our lives — personal, social, cultural, environmental, and economic. Her trove of written work and public appearances shape a vision of our greater selves working together to achieve more than the sum of our separate lives. Now, in the midst of the COVID-19 pandemic, the reality of overwhelming separation, grief, loss, and social distancing begs the question: Is it truly possible to achieve partnership values? Sometimes, we need to step away from news reports and social media to seek comfort in the stories that make positive differences in our lives. In this article, the author shares a story, more than three decades in the making, of a small group of committed volunteers who tackle a most difficult and disturbing form of oppression — child sexual abuse. An annual camp program, first requested by child survivors themselves, is deeply linked to partnership system ideologies. The Victory Over Child Abuse (VOCA) Camp story actualizes partnership values by firmly wrapping them around a tenacious vision of intentionally safe community. When communities commit to partnership systems, healing and non-violence become the norm, social transformation is possible, and children are safe.

Published: April 2021

Esta investigación que abarca dos fases, inicialmente busca la apropiación del término de “resiliencia” a los acuíferos en zonas de posconflicto. Hoyen día, existen distintas aplicaciones de este término a diferentes ramas de las ciencias, pero aún, no hay una caracterización propia asociada alos acuíferos. ¿Cómo se puede apropiar este concepto a los acuíferos? ¿Existe alguna incidencia directa e indirecta del posconflicto a esteconcepto de resiliencia? ¿Cómo puede cuantificarse este concepto? Pues bien, este artículo dará respuesta a los dos primeros interrogantes quehacen parte de la fase inicial, en donde se usará una metodología de tipo descriptivo-cualitativo a través de exploración de documentos y trabajo de campo. Una vez aplicada dicha metodología, se podrá tener claridad del concepto de resiliencia en acuíferos y su incidencia con el posconflicto en Colombia, especialmente la zona de Puerto Boyacá, para luego, entrar en una fase dos de elaboración de matrices EIA y modelación que darán respuesta al interrogante tres en otro documento.

En el presente artículo se aborda el trabajo de investigación diseño e implementación de modelos orientados hacia el máximo aprovechamiento de las tecnologías de la información y la comunicación (TIC) en el contexto de la construcción de un estado abierto, eficiente, transparente, y participativo, que permita la prestación de servicios colaborativos para la comunidad.
Estos modelos se diseñan de acuerdo con los lineamientos de la administración pública, en términos del artículo 39 de la Ley 489 de 1998 y enmarcadas en el Plan Nacional de Desarrollo (PND) y los programas transversales de la gestión pública. Para este caso se trata de profundizar en el campo de la arquitectura empresarial (AE) como uno de los instrumentos que posibilita la puesta en marcha de proyectos soportados en TIC en Colombia.
Se considera la arquitectura empresarial (AE) como uno de los principales elementos estratégicos, cuyo fundamento teórico y operativo hace parte del análisis integral de las entidades gubernamentales, desde diferentes perspectivas y dimensiones, estas miradas críticas de las instituciones constituyen el insumo para poder realizar diagnósticos – pronósticos capaces de generar propuestas y alternativas que contribuyan a la transformación y modernización de las instituciones con base en el uso y la apropiación de tecnologías de la información y la comunicación (TIC).
Para el logro de los objetivos de implementación de las TIC y su aplicación en el campo de administración y la gobernanza, es fundamental partir del Marco de Referencia de AE para la gestión de tecnologías, aquí se trata de establecer un modelo de referencia para ser implementado como estructura orientadora de la arquitectura empresarial (AE). El
marco de referencia o marco teórico, sobre la base de la estructura conceptual, consiste en la definición de los lineamientos sobre las prácticas significativas (memorables, significativas), que se han realizado con base en la utilización e implementación de las AE en el contexto de las tecnologías de la información y la comunicación (TIC).
El Repositorio de Arquitectura Empresarial del Gobierno (GEAR), se ha destacado por ser una de las estrategias de gobernabilidad en línea; este se soporta legalmente en el artículo 209 de la Constitución Política, el 3º de la Ley 489 de 1998 y 3º de la Ley 1437 de 2011, que establece los parámetros para la prestación de servicio de alta calidad, sobre la estrategia de la reutilización de datos públicos, su tratamiento y estandarización, lo mismo que su neutralidad, innovación y colaboración. Los fundamentos de la estrategia son desarrollados a partir de 4 componentes que facilitarán la masificación de la oferta y la demanda de Gobierno en línea. Estos son, TIC para servicios, TIC para el Gobierno abierto, TIC para la gestión y seguridad y privacidad de la información.
