Досліджено вплив синтетичних низькомолекулярних сполук — похідних піразолу — на ріст і розвиток рослин томата (Solanum lycopersicum L.) сорту Money Maker в умовах in vivo та in vitro. Встановлено, що найбільш виражену активність в умовах in vivo виявляє сполука D-pyrazole-3 у концентрації 10–8 М. Вперше досліджено вплив цих сполук на морфогенетичний потенціал експлантів S. lycopersicum в умовах in vitro і показано, що сполуки D-pyrazole-1, D-pyrazole-2 і D-pyrazole-3 ефективно індукують калюсогенез та ризогенез, а також, залежно від концентрації, пряму регенерацію рослин в умовах in vitro. Під дією всіх трьох сполук як у концентрації 10–9 М, так і 10–8 М найефективніше коренеутворення відбувається на пагонових експлантах. Для прямої регенерації рослин із цього типу експлантів найбільш ефективними є сполуки D-pyrazole-1 у концентрації 10–9 М або D-pyrazole-2 у концентрації 10–8 М, які в подальшому можуть бути рекомендовані для використання в біотехнологічних дослідженнях з генетичного вдосконалення S. lycopersicum.

It has been found that the methodological principles of building a legal model of sustainable development of Ukraine remain imperfect. In this regard, it is argued that the basis of the legal model, first of all, shall be assigned general and sectoral legal principles that will create the theoretical base of normative activity. In particular, it has to be that the Rule of Law principle has a particularly specific content and acquires signs of a particular legal instrument in the process of law-making and law enforcement. Accordingly, the use of the Rule of Law principle in the process of assessing the efficiency of legal norms is proposed, which will talk about promoting the legal act of the ideology of justice. It is necessary to unacceptable laying into the legal model of sustainable development of the false concept of legal regulation of economic relations, which provides for the exclusion from the legal system of the state of certain branches of legislation, in particular economic legislation. It is substantiated that the Economic Code of Ukraine is the basis for achieving the goals of sustainable development on the economic component and synergistic associated with other acts of Ukrainian legislation in the environmental and social spheres. In this regard, it is argued that the effectiveness of the legal model of sustainable development will be significantly higher, subject to preservation in the legal system of the Economic Code of Ukraine, which will additionally testify to compliance with the Rule of Law principle. It is emphasized that in the light of the adaptation of Ukrainian legislation, including economic, to the EU Law and the signing of the Association Agreement between Ukraine and the EU, the influence of international legal norms on the state and directions of development of individual institutions of Economic law, which contributes to the universalization of the legal model of the steady the state's development.

The main purpose of this research is to analyze the state and possibilities of application of economic and legal instruments for increasing efficiency of waste management in post-conflict areas and offer ways of their improvement taking into account regional features. On the example of Donetsk region, the article considers the current state and prospects of regional planning in the field of waste management in post-conflict territories. It is shown different features and elements of the new planning system in this field including the National Waste Management Strategy until 2030. Special attention is given to analysis of the Guidelines for the development of regional waste management plans, which were adopted in September 2021. This document does not take into account the peculiarities of post-conflict territories due to ongoing hostilities, as well as related problems and threats, which influence decision-making in the field of waste management. Based on this, it is necessary to reflect these peculiarities in sections of regional plan that cover the characteristics of region and the analysis of the current state of waste management system in region. Possibilities of industrial parks for waste recycling in post-conflict territories are considered. Studies indicate that industrial parks created on the new site (“greenfield”) have significant advantages over parks located in former industrial zones on the basis of existing infrastructure (“brownfield”). The latest novelties of the Law of Ukraine “On Amendments to the Law of Ukraine “On Industrial Parks” aimed at attracting investment in the industrial sector of the economy by introducing incentives in industrial parks” (entered into force on October 7, 2021) are also investigated. Offers to improve the legal framework for industrial parks for waste recycling in post-conflict territories are substantiated.

The article deepens theoretical and methodical provisions on the attractive image formation for the territorial communities in terms of systematization of their identification criteria and positioning parameters, strengthened in this context local innovative aspect of the implementation of sustainable development concept. The theoretical and methodical provisions regarding the marketing tools of economic entities at the local level have been analysed, which made it possible to research the territorial community as a complex and innovatively active system characterized by emergence and synergistic metasystem connections between its elements that require ordering. This ordering became possible due to the methodological research platform, which based on the positions of the systemic and integrated approach, D. Forrester counterintuitive method of system dynamics, A. Marshall partial equilibrium approach and the principle of stable disequilibrium. The authors proved that the process of determining and ordering identification criteria and positioning parameters depends on the existing institutional frames for the functioning and development of territorial communities, which have a narrowing effect on the search opportunities and alternatives in choice. The discreteness of the coverage of the unique characteristics, which made it possible to distinguish the community among many others based on the established scientific hypothesis, justified the choice of 15 identification criteria and 13 positioning parameters that form the idea of a territorial unit. The provisions of the article systematized of certain criteria and parameters by constructing appropriate classification schemes based on a descending hierarchical chain of classification taxa “class – type – criterion / parameter – result (value) of criterion / parameter”. This made it possible to distinguish between the classes of identification criteria into key and auxiliary ones, and the classes of positioning parameters into single (quantitative) and complex (qualitative) ones. The article proves importance of the implementation of identification criteria and positioning parameters in the practice of the territorial communities strategizing to improve their innovative activity and determine key development positions in a strategic perspective.

The article summarizes scientific approaches to the economic security of the region in the context of its positioning. The key risks of economic security of the Ukrainian regions have been identified as well as the most important criteria for regions positioning: the gross regional product (GRP) structure, the volume and rates of industrial development, the volume and dynamics of investments; natural resource production and scientific and technical potential; resource efficiency; competitiveness of the region's economy; unemployment rate; the quality of life, the degree of income differentiation, the provision of the population with material benefits and services; energy dependence; integration into the national economy etc. It is noted that the main problem of economic security is to ensure effective management of regional policy, as well as the evaluation of the regions positioning in the context of economic security can be carried out in the main directions: the level of poverty and unemployment in the region; the quality of life of the population; demographic component of the socio-economic security of the region; the ability of the region's economy to sustainably grow; stability of the region's financial system; support of the scientific potential of the region; dependence of the region's economy on imports of the most important types of products; relations of the region with the countries of the European Union. The modern positioning of some security sectors and the consequences of such positioning have been characterized. A system of main indicators has been formed that allows to quantify the level of economic security of the region in the context of its positioning. The methodical approach to evaluating the economic security of a region in the context of its positioning is highlighted. It is noted that despite the goals that are taken into account when positioning the region, the whole process can be structured into the following blocks: organizational and analytical support; methodical and informational support; conceptual software. The article presents the functional components of the mechanism for ensuring the economic security of regions in the context of their positioning. It has been proved that the effective functioning of the mechanism for ensuring the economic security of regions in the context of their positioning requires the effective functioning of all subjects synchronously, which made it possible to formulate a synergistic effect in a formalized form.

The paper substantiates the need to assess the harm of food for consumers with chronic diseases or allergies, which is important to prevent possible deterioration of the disease or eliminate acute allergic reactions of the human body to harmful ingredients present in the product. It is proved that currently there is no convenient intelligent system that could recognize the composition of products on the Ukrainian market, provide product characteristics and assess the harmfulness of the product. It is proposed to use food labels and packaging as primary sources of food information that is available to the consumer. It is shown that the printed information on the packages is presented in text-graphic form. The development of a mobile system as a software solution for the detection and analysis of textual and graphical information on the composition of products based on the use of artificial intelligence methods is proposed and substantiated. The block diagram of the intelligent mobile system for detection and analysis of food composition has been developed. The MSER algorithm is used to select text regions on the input image matrix in the presented algorithmic software. The solution to the problem of character recognition was based on the use of convolutional neural network MobileNet-V2, which is currently the best option in the classification of images by mobile applications that do not have a server part, and therefore large computing resources. Alignment of text on the image was carried out using the method of finding a rectangle with the smallest area Developed algorithms for grouping words. A decision support algorithm has been proposed to assess the harmfulness of products. The developed system allows personalized selection of food for each individual user, ie, the assessment of the composition of products is calculated taking into account the state of health of use, existing threats, diseases, restrictions or allergies
Search for identical regions in images using invariant moments

One of the ways to describe objects on images is to identify some of their characteristic points or points of attention. Areas of neighborhoods of attention points are described by descriptors (lots of signs) in such way that they can be identified and compared. These signs are used to search for identical points in other images. The article investigates and establishes the possibility of searching for arbitrary local image regions by descriptors constructed with using invariant moments. A feature of the proposed method is that the calculation of the invariant moments of local areas is carried out with using the integral representation of the geometric moments of the image. Integral representation is a matrix with the same size as the image. The elements of the matrix is the sums of the geometric moments of individual pixels, which are located above and to the left with respect to the coordinates of this element. The number of matrices depends on the order of the geometric moments. For moments up to the second order (inclusively), there will be six such matrices. Calculation of one of six geometric moments of an arbitrary rectangular area of the image comes down up to 3 operations such as summation or subtraction of elements of the corresponding matrix located in the corners of this area. The invariant moments are calculated on base of six geometric moments. The search is performed by scanning the image coordinate grid with a window of a given size. In this case, the invariant moments and additional parameters are calculated and compared with similar parameters of the neighborhoods of the reference point of different size (taking into account the possible change in the image scale). The best option is selected according to a given condition. Almost all mass operations of the procedures for calculating the parameters of standards and searching of identical points make it possible explicitly perform parallel computations in the SIMD mode. As a result, the integral representation of geometric moments and the possibility of using parallel computations at all stages will significantly speed up the calculations and allow you to get good indicators of the search efficiency for identical points and the speed of work

Some issues of the use of unmanned aircraft and space vehicles in monitoring the consequences of technical and environmental events and precision farming are considered. The proposed technology is aimed at improving the recognition accuracy of infrastructure objects with obtaining the numerical values of their 3D coordinates. The aim of the research is to improve the quality of monitoring using neural network identification and classification of objects in multi-zone satellite images obtained from unmanned aerial vehicles (UAV). Research includes both theoretical research and applied problem solving. The mathematical basis of image processing is the image recognition computer. Practical research is based on experimentation, software implementation, testing of algorithms and technology. An effective method of video surveillance of the territory has been improved. The task of the authors' research is to improve the accuracy of objects recognition on the earth's surface (specific infrastructure objects, the sky, the state of vegetation of agricultural land). The authors have experience in this area. The solution to this problem occurs simultaneously in two directions. The first direction: the technical result is ensured by the fact that the technology offers the use of a UAV equipped with two video cameras. The second direction is the use of scientific idea consisting in the development of a method for joint computer processing of digital and analog images obtained from UAVs, as well as quasi-simultaneous and reusable multi-zone satellite images. A new result of the research is the developed data structure for storing the model of the recognition process, which allows to jointly save dissimilar characteristics and membership functions of different types in the same tables

To date the recognition of universal, a priori inherent in them connection between the objects of the world around us is quite rightly considered almost an accomplished fact. But on what laws do these or those sometimes rather variegated systems function in live and inert nature (including - in modern computer clusters)? Where are the origins of their self-organization activity lurked: whether at the level of still hypothetical quantum-molecular models, finite bio-automata or hugely fashionable now artificial neural networks? Answers to all these questions if perhaps will ever appear then certainly not soon. That is why the bold innovative developments presented in following article are capable in something, possibly, even to refresh the database of informatics so familiar to many of us. And moreover, in principle, the pivotal idea developed here, frankly speaking, is quite simple in itself: if, for example, the laws of the universe are one, then all the characteristic differences between any evolving objects should be determined by their outwardly-hidden informative (or, according to author’s terminology - “mental") rationale. By the way, these are not at all empty words, as it might seem at first glance, because they are fully, where possible, supported with the generally accepted physical & mathematical foundation here. So as a result, the reader by himself comes sooner or later to the inevitable conclusion, to wit: only the smallest electron-neutrino ensembles contain everything the most valuable and meaningful for any natural system! At that even no matter, what namely global outlook paradigm we here hold

Published: December 2021

ABSTRACTThe present-day English language learning is characterized by educational potentials of digital technology for informal learning context. However, research examining EFL learners’ characteristics on self-directed use of digital devices for language learning remains a paucity of evidence. Addressing this current issue, the present study aims to shed some light on English language learners’ beliefs and practices on informal digital learning of English beyond classroom. A total of 117 Indonesian EFL learners participated in this study through a 5-point Likert-scale survey and semi-structured interview. The results revealed the disparity between the EFL learners’ beliefs and practices on informal digital learning of English. These EFL learners surely believed that informal digital learning activities could significantly enhance the target language skills, but they slightly engaged in digital learning activities beyond the classroom schedule. The results of semi-structured interviews further delineated that use of native languages in their social circle relationships and limitations of the digital devices used became particular reasons for this circumstance. The results contribute to the realm of English language teaching to reach the possible synchronicity between teacher-designed in-class and out-class digital learning activities and students’ language learning styles and preferences to achieve the success of target language learning.ABSTRAKPembelajaran bahasa Inggris masa kini bercirikan potensi pendidikan teknologi digital untuk konteks pembelajaran informal. Namun, penelitian yang meneliti karakteristik pelajar EFL tentang penggunaan perangkat digital secara mandiri untuk pembelajaran bahasa masih tetap kekurangan bukti. Mengatasi masalah saat ini, penelitian ini bertujuan untuk menjelaskan keyakinan dan praktik pembelajar bahasa Inggris tentang pembelajaran digital informal bahasa Inggris di luar kelas. Sebanyak 117 pelajar EFL Indonesia berpartisipasi dalam penelitian ini melalui survei skala Likert 5 poin dan wawancara semi terstruktur. Hasilnya mengungkapkan perbedaan antara keyakinan dan praktik pelajar EFL pada pembelajaran digital informal bahasa Inggris. Pembelajar EFL ini pasti percaya bahwa kegiatan pembelajaran digital informal dapat secara signifikan meningkatkan keterampilan bahasa target, tetapi mereka sedikit terlibat dalam kegiatan pembelajaran digital di luar jadwal kelas. Hasil wawancara semi-terstruktur lebih lanjut menggambarkan bahwa penggunaan bahasa asli dari hubungan lingkaran sosial mereka dan keterbatasan perangkat digital yang digunakan menjadi alasan khusus untuk keadaan ini. Hasilnya berkontribusi pada ranah pengajaran bahasa Inggris untuk mencapai kemungkinan sinkronisitas antara kegiatan pembelajaran digital di dalam dan di luar kelas yang dirancang guru dan gaya dan preferensi belajar bahasa siswa untuk mencapai keberhasilan pembelajaran bahasa target.

ABSTRACTThis research investigated the interaction effects between gender and Learner-Centered Teaching Strategies toward learners' writing performance. The study was a quasi-experiment using tests as the research instrument. The participants were 72 learners of the English Department at a state institution consisting of 34 males and 38 females. The class was classified into two parts: experiment groups consisting of self-directed learning class (SDL), discovery learning class (DL), and small group discussion class (SGD); and a control group: lecturing class (L). A two-way ANOVA was used for data analysis. The findings confirmed a significant difference by gender (F=10.629. Sig. 0.002<0.05); and Learner-Centered Teaching Strategies F=20.658. Sig. 0.000<0.050) on the learners' writing performance. It also indicated that females (means score 73.46) were higher than males (means score 64.45). In contrast, no interaction effect simultaneously occurred among gender and the Learner-Centered Teaching Strategies (F 2.70) = 2.301. Sig. 0.086>0.050).  Both of them did not contribute simultaneously to writing performance. Lastly, the r squared was 0.574 indicating a high correlation of teaching strategies and gender (57%). The teachers were suggested to apply learner-centered teaching strategies in an L2 writing class at a higher education level.ABSTRAKPenelitian ini menyelidiki pengaruh interaksi antara gender dan strategi pengajaran terpusat pada peserta didik terhadap kinerja menulis peserta didik.

ABSTRACTGuessing game is a part of Communicative Language Teaching (CLT), which will create an atmosphere for students to increase the desire to learn languages. However, learning with games makes students undisciplined and requires a long time. This study aims to determine the effect of learning English using a guessing game method on the speaking skills of elementary school students. The study is a one-group pretest-posttest design implemented at the Islamic Elementary School in Yogyakarta. The study sample consisted of 68 students in grade 6 in 2019. The sampling technique used was total sampling. The measured learning outcomes are speaking skills in pronunciation, vocabulary, grammar, fluency, and understanding. The data were processed using the Wilcoxon test. The results showed that the students' speaking skills improved after learning with guessing games. The speaking skills that improved significantly are pronunciation, vocabulary, and fluency. Grammar and comprehension, on the other hand, improved but not significantly. The conclusion is that the guessing game can improve the students' speaking skills even though it has not covered all of its aspects.ABSTRAKGame menebak merupakan bagian dari Communicative Language Teaching (CLT) yang akan menciptakan suasana bagi siswa dalam meningkatkan keinginan untuk belajar bahasa.

Acceptable Risks in Pediatric Research: Views of the US Public
Authors: Schupmann Will , Li Xiaobai , Wendler David
Published: December 2021

BACKGROUND AND OBJECTIVES

Critics argue that it is unethical to expose children to research risks for the benefit of others, whereas many regulations permit “net-risk” pediatric research but only when the risks are minimal. In the present survey, we assessed whether the US public agrees with these views and whether the US public’s views regarding the acceptability of net-risk pediatric research are influenced by its social value.

METHODS

A 15-minute survey of a nationally representative sample of US adults. Participants were randomly assigned to 1 of 4 hypothetical scenarios involving procedures that pose increasing levels of risk. To assess whether respondents’ views on the acceptability of the risks is influenced by the social value of the research, in each of the 4 scenarios we described the respective procedure being used in 3 studies with increasing levels of social value.

RESULTS

A total 1658 of the 2508 individuals who were sent the survey link participated (response rate = 66.1%). Approximately 91% approved of a research blood draw in minors, and ∼69% approved of a research bone marrow biopsy. The proportion who indicated that the respective procedure was acceptable increased as the study’s social value increased. This effect was significantly stronger for studies which pose greater risks compared with studies with lower risks (P < .001).

CONCLUSIONS

The vast majority of the US public supports net-risk pediatric research that poses minimal risk, and a majority supports net-risk pediatric research that poses somewhat greater risks, provided it has high social value. These findings offer important information for assessing when it is acceptable to conduct net-risk pediatric research.
Образ Г. П. Ґалаґана на сторінках журналу «Киевская старина».

Мета статті полягає у виявленні механізмів конструювання прижиттєвого та меморіального образів одного із значимих представників дворянства Лівобережної України Григорія Павловича Ґалагана (1819–1888). Актуальність роботи визначено можливостями включення обраної теми до різноманітних міждисциплінарних контекстів біографістики, соціальної, політичної, культурної та інтелектуальної історії. Історіографічна експертиза виявила, що питання ролі і місця дворянства в історії залишається дискусійним, а тому його вивчення зберігає актуальність. Методологічну основу сформували базові принципи теорії історіографічного образу, що спрямовували на виявлення ґенези, формування та еволюції уявлень стосовно Г. П. Ґалагана на сторінках часопису «Киевская старина». Ми виходили із розуміння того, що історичне знання та суспільні історичні уявлення формуються шляхом вибіркового відображення і трансляції минулого у професійному середовищі та публічному просторі. Саме тому предметом нашої уваги став процес конструювання прижиттєвого та меморіального образів лідера дворянства Лівобережної України, який розпочався іще за його життя на сторінках «Киевской старины». Саме тому джерельна база дослідження була сформована з публікацій в «Киевской старине» біографічних документів та праць самого героя. Основні результати полягають у визначенні змістовних структур прижиттєвого та меморіального образів Г. П. Ґалагана: покровитель місцевої освіти, справжній патріот Батьківщини, активний захисник інтересів її населення, видатний меценат, поціновувач та захисник традиційної народної культури. Виявлені мотиви творення такого ідеалістичного образу були обумовлені завданнями поміркованого сегмента національного руху кінця XIX – початку ХХ ст.: необхідністю плекання і зміцнення місцевого патріотизму, української або малоросійської ідентичності, важливістю формування пантеону знакових національних діячів, вихованням у заможних земляків ставлення до матеріальної підтримки національної справи як до морального обов’язку, важливої, статусної справи.

Джерела: архівні документи російських жандармів, опубліковані автобіографічні матеріали П. С. Єфименка, спогади та щоденникові записи сучасників тощо. Основні результати полягають у з’ясуванні особливостей формування світогляду Петра Єфименка: в дитинстві, в гімназичний та студентський періоди. Показано, що П. Єфименко розпочав збирати українські фольклорно-етнографічні матеріали, брав участь в українських осередках молоді в Харкові. Він став активним учасником Харківсько-Київського таємного товариства. У цьому середовищі, окрім українських народолюбних симпатій, поширювалися російські радикально-демократичні ідеї. Українські народолюбні погляди П. Єфименка продовжували формуватися й під час навчання в Московському університеті. Встановлено, що наприкінці 1850-х рр. тривали його ідейні пошуки. В Університеті Св. Володимира відбувся остаточний ідейний поворот П. Єфименка від ідей російської радикальної демократії до українського народолюбства. Стислі висновки. Доведено, що впродовж 1850-х рр. П. Єфименко сформувався як прихильник ідей українського народолюбства та українознавець. Практичне значення статті в тому, що представлений матеріал матиме інтерес для фахівців у контексті вивчення етнонаціональної та суспільно-політичної історії України ХІХ ст. Оригінальність статті полягає в осягненні маловивчених аспектів формування світогляду українського діяча. Наукова новизна в актуалізації процесу формування світогляду П. Єфименка. Тип статті: описово-аналітичний.
Technical Efficiency and Public Policies in Agriculture: An Analysis for the Eastern Amazon Region
Authors: Silva Juliana de Sales
Published: December 2021

The agricultural sector in one of the most dynamic industries of the Brazilian economy and is responsible for about 30% of the GDP of the state of Pará, located in the Brazilian Eastern Amazon region. This is mainly due to the public policies developed for the sector, with emphasis on the National Policy of Technical Assistance and Rural Extension (PNATER) and Rural Credit, in addition to conditional cash transfer programs such as Bolsa Família (Family Allowance). Given this scenario, the purpose of this research is to determine the technical efficiency of the agricultural rural facilities of Pará, and observe the effect of these policies on their inefficiency. The methodology employed in order to achieve these objectives is the stochastic frontier approach, and the data used was obtained from a special tabulation based on the 2006 Agricultural Census. The main results evidence that rural credit policies, social welfare programs, and technical support are important to reduce the technical inefficiency of the rural facilities of the State of Pará. The latter, however, is not statistically significant.

Tecnología del gas natural
Authors: Latorre Chacón Leonardo
Published: December 2021

Este artículo presenta conocimientos, entre la academia y la experiencia, propios de la ingeniería aplicada al manejo del gas natural, atendiendo la realidad del país y el interés expresivo de los docentes y estudiantes de la Universidad Nacional por integrarlos en la actividad corriente de estudios, especializaciones, proyectos de grado, investigación de productos, ingeniería de procesos y control ambiental. Ilustra definiciones básicas y los usos del gas dentro del modelo de recuperación de productos licuables y la masificación para uso como combustible. Incluye una guía de algunos productos químicos que derivan del gas natural, no obstante que el destino hacia materia prima petroquímica, aunque deseable, es secundario en las prioridades de la estrategia establecida de aprovechamiento de las reservas probadas de este valioso recurso de la economía nacional.
Por otra parte, expone varias normas como algunos estándar ISO disponibles en el ICONTEC que tratan sobre especificaciones de calidad y ensayos de laboratorio referidas especialmente al transporte por gasoductos y distribución comercial pero aplicables a todas las etapas de la ingeniería de los proyectos. Finalmente recomienda bibliografía referente al gas natural cuya disponibilidad en bibliotecas y laboratorios motivarían la participación de las diversas carreras de la Facultad de Ingeniería en las actividades profesionales de esta industria.
Parámetros de operación en las combinadas
Authors: Chaparro Castro José Manuel
Published: December 2021

Las combinadas realizan diversas funciones que permiten la recolección de granos directamente del campo en un proceso de corte del tallo de la planta, el transporte del material cortado, la trilla o desprendimiento del grano de la espiga, la separación del material diferente al grano de éste, y la limpieza del grano previamente separado. A través de análisis dinámico, o de experiencias empíricas, ha sido posible establecer algunos parámetros de operación de acuerdo con el cultivo recolectado, que permiten trabajar con más eficiencia la combinada.
En ensayos, realizados a lo largo de los últimos quince años, hemos confrontado los parámetros expuestos por diferentes autores y hemos probado la validez de los mismos. En el presente trabajo se da información sobre estos parámetros de operación y su aplicación en la operación de cosecha considerando que cuando estos son tenidos en cuenta, las pérdidas durante la cosecha son mínimas.

El colapso del puente Samaná: un nuevo enfoque
Authors: Cifuentes Cifuentes Gustavo
Published: December 2021

El 3 de octubre de 1993, colapsó la superestructura del puente sobre el río Samaná en la carretera Bogotá — Medellín, en Colombia. La Facultad de Minas de la Universidad Nacional, en Medellín, llevó a cabo un estudio que señala como causa probable del colapso, la falla de la unión de la armadura inferior con un pendolón.
Un nuevo estudio analítico realizado en 1996, por la Facultad de Ingeniería de la Universidad Nacional, en Bogotá, indica que el puente tenía problemas de estabilidad general, los cuales se presentan en este artículo, y se indican como posible causa del colapso. Así mismo se muestran algunas soluciones dadas al problema para un puente gemelo.

De Alemania a México: Samuel Chávez y la gimnasia rítmica del Instituto Dalcroze, 1912-1922
Authors: Sifuentes Solís Marco Alejandro , García Díaz Jorge Refugio , Acosta Collazo Alejandro
Published: December 2021

El objetivo central de esta entrega es dar a conocer a la comunidad de historiadores, en especial a los historiadores de la arquitectura, una faceta poco explorada del arquitecto Samuel Chávez (oriundo de la ciudad de Aguascalientes pero cuyo desarrollo profesional tuvo como centro la Ciudad de México), consistente en el interés que mantuvo por la relación entre arquitectura, danza y música; a tal efecto, el texto ofrece evidencia histórica y argumentos fundados tanto en la interpretación de un corpus de documentos de su archivo personal, que hasta donde se sabe no ha sido trabajado por la historiografía especializada, como en hemerografía de la época y fuentes secundarias actuales. Más allá de lo afirmado por Raquel Tibol (1984), en el sentido de considerar a Samuel Chávez como uno de los precursores de la danza moderna en México, nuestra aportación consiste en documentar, de manera contextualizada, el punto de encuentro de nuestro arquitecto con el centro pedagógico clave de los movimientos para la reforma de la vida: el Instituto de Rítmica de Jaques Dalcroze, sito en la ciudad-jardín alemana de Hellerau, lo que supuso una inflexión en la trayectoria profesional de Chávez al liberarse de las ataduras de su formación Beaux-arts y vincularse a la vanguardia europea del momento. Nuestra entrega sólo se centra en el período 1912-1922.
