Authors: Иванов Д.А.
Published: August 2021

Для волнового уравнения на промежутках докритической длины рассмотрены задачи с двусторонними граничными управлениями трех основных типов в классах слабых обобщенных решений. Для устойчивого приближенного вычисления граничных управлений предложен метод, основанный на предварительном сглаживании фазовых траекторий, применении вариационного метода в классах сильных обобщенных решений и финальном дифференцировании найденных сглаженных управлений. Приведены вычислительные иллюстрации.

Problems with two-sided boundary controls of three main types are considered for the wave equation in the classes of weak generalized solutions on intervals of subcritical length. An algorithm is proposed for the stable approximation of boundary controls. This algorithm is based on the preliminary smoothing of phase trajectories, the application of a variational method in the classes of strong generalized solutions, and the final differentiation of the resulting smoothed controls. Numerical results are discussed.

Рассматривается ускорение параллельных гидродинамических расчетов на кластерах с CPU- и GPU-узлами. Для тестирования используется собственный CFD-код SigmaFlow, портированный для расчетов на графических ускорителях с помощью технологии CUDA. Алгоритм моделирования течения несжимаемой жидкости основан на SIMPLE-подобной процедуре и дискретизации с помощью метода контрольного объема на неструктурированных сетках из тексаэдральных ячеек. Сравнение скорости расчета показывает высокую производительность графических ускорителей нового поколения в GPGPU-расчетах.

Speedup of parallel hydrodynamic calculations on clusters with CPUs and GPUs is considered. The CFD SigmaFlow code developed by the authors and ported for GPU by means of CUDA is used in test calculations. The incompressible flow simulation is based on a SIMPLE-like procedure and on a discretization by the control volume method on unstructured hexahedral meshes. The performance evaluation shows a high efficiency of the new generation of GPUs for GPGPU calculations.

We report the case of a 39-year-old male with Persistent Apical Periodontitis (PAP) caused by infection in an uninstrumented area, wherein conventional chemical root canal treatment is not possible, which was sterilized via highfrequency conduction. He underwent root canal filling after multiple endodontic treatments for tooth #4. As symptoms recurred, he was referred to our department with the chief complaint of dull pain during mastication. Present symptoms were percussion pain of the tooth, buccal mucosa swelling at the apical portion, and grade 1 mobility. Radiography revealed inadequate root canal filling. A radiolucent image 5×6 mm in diameter and with an unclear boundary was observed around the apex. External root resorption was mainly observed in the apical foramen, with a crown root ratio of approximately 1:1. Using 6% sodium hypochlorite under dental microscopy, chemomechanical root canal preparation was performed. Passive ultrasonic irrigation and calcium hydroxide application were conducted three times; however, periapical tissue inflammation did not subside. Therefore, the patient was diagnosed with PAP, and the uninstrumented area was sterilized via high-frequency conduction. High-frequency currents were applied to the apex, root surface, and periapical lesion at 500 kHz and 90 V; periapical tissue inflammation resolved after 2 weeks. Subsequently, the root canal was filled. Follow-up radiography revealed a bone regeneration-like image at 2 months. Bone defects healed at 11 months. Although surgical endodontic therapy is conventionally performed in PAP patients, high-frequency conduction could be a minimally invasive nonsurgical endodontic treatment option for uninstrumented areas in PAP patients.
Modelo de análisis de la reputación personal en contexto político. Un caso de estudio de tres mujeres líderes ecuatorianas
Authors: Baquerizo Gabriela
Published: August 2021

Este trabajo tiene como objetivo realizar una contribución metodológica al campo de estudio de la reputación personal, a través de la propuesta de categorías de análisis del proceso de construcción de la reputación personal en un contexto político. Para ello, se seleccionaron tres mujeres líderes políticas reconocidas como fuentes periodísticas de los diarios de mayor tiraje de Ecuador (El Universo y El Comercio): Lourdes Tibán, Cynthia Viteri y Nathalie Cely. Así, de un universo de 2203 notas de prensa, se obtuvo una muestra estratificada de 328 publicaciones, que se sometieron al análisis textual para conocer cómo proyectan los diarios las dimensiones técnica, psicoemocional y ética de reputación y de liderazgo en esas mujeres. Después del análisis mediático, se realizaron entrevistas en profundidad semiestructuradas a estas mujeres y a sus allegados y, mediante la técnica de análisis textual, se determinó cuál es la percepción que tienen sobre su propia reputación y liderazgo y cómo las perciben sus allegados. Con esto, se realiza una triangulación metodológica (tomando los resultados de los medios de comunicación y las entrevistas), de la que resulta la propuesta de un modelo de análisis que se enmarca en la teoría de la influencia social y gestión de impresiones, la cual procura identificar las estrategias de comunicación asertiva que influyen en la construcción de la reputación personal en un contexto político. Como hallazgos, se obtuvo que las tácticas asertivas y defensivas son elementos que emplean estas mujeres en la construcción de su reputación. También se pudo observar que la confrontación es una categoría propia de estas mujeres, rasgo que se contradice con la tradición clásica de estereotipo femenino.
El impacto de los anuncios de Instagram en el incremento de ventas en restaurantes Caso Miyagi Sushi en la ciudad de Guayaquil
Authors: Lozano Cristian
Published: August 2021

Las redes sociales han pasado de ser espacios de conectividad entre personas para convertirse en medios publicitarios en los que negocios de cualquier índole pueden anunciarse y dar a conocer sus productos y servicios. En concreto, Facebook, como empresa, ha desarrollado en los últimos años una plataforma de anuncios que renovó el concepto de la publicidad en general. El presente estudio tiene por objetivo analizar el impacto que tienen los anuncios en Instagram en el incremento de ventas de Miyagi Sushi, un restaurante de entrega de sushi a domicilio en Guayaquil, Ecuador. A partir de un análisis de los datos obtenidos por la plataforma de anuncios de Facebook respecto a las campañas de anuncios realizadas por el restaurante en Instagram entre agosto y noviembre de 2020, así como de las ventas obtenidas en ese mismo período, se buscó determinar si existe una correlación entre mayor inversión publicitaria y más ventas. Los resultados reflejaron que, en promedio, en los días en los que hubo más inversión en anuncios en Instagram también hubo un incremento de las ventas. A través de una fórmula estadística que mide el retorno de la inversión publicitaria, se calculó que por cada dólar invertido en publicidad en esta red social, Miyagi Sushi hizo 4,61 dólares. Como recomendaciones finales se propone un análisis del tema cambiando algunas variables analizadas, con el fin de conocer con mayor profundidad la correlación causal entre inversión publicitaria digital y ventas.

Published: August 2021

Aim. To investigate the modern condition of the problem of infertility and obstetric complications in endometriosis and the main management aspects of women with endometriosis in pregnancy planning.
Materials and methods. The article presents a systematic literature review on the results of search for studies in electronic databases MEDLINE, PubMed, EMBASE, Cochrane Library and eLibrary.
Results. Endometriosis is one of the most common causes of infertility. A cascade of adverse reactions caused by endometriosis prevents a successful pregnancy. Currently, there is an evidence that patients with endometriosis have a high risk of several obstetric complications, such as spontaneous miscarriage, premature birth, preeclampsia, low birth weight and gestational diabetes. Progestogens belong to the first line of therapy of endometriosis, and dydrogesterone is a drug that meets all the necessary requirements. The use of dydrogesterone in the treatment of endometriosis helps to reduce the negative symptoms of endometriosis, improve the quality of life and increase fertility. Dydrogesterone is the only progestogen that has two effective regimens for endometriosis, which allows prescribing therapy for women who are planning pregnancy and for those who have already realized their reproductive plans. Dydrogesterone is the only progestogen that has been suggested to increase the chances of pregnancy in women with endometriosis. Dydrogesterone has been shown to be effective in supporting the luteal phase in ART programs, treating threatening and recurrent miscarriages.
Conclusion. Endometriosis is associated with infertility and a high risk of obstetric complications. Dydrogesterone has a number of advantages compared to other progestogens.

Published: August 2021

Pelvic organ prolapse is a pathology that extremely worsens the quality of life of a woman at any age. Usually, this pathology is encountered in patients of the older age group, where the correction of the pathology is reduced to improving the quality of life. Other challenges are pelvic organ prolapse in women of reproductive age, and especially in combination with pregnancy. The task of obstetricians and gynecologists in this situation is not only to preserve and prolong pregnancy, to choose an adequate method of delivery that is optimal for the mother and newborn, but also to correct the anatomical location of the genitals, which requires certain surgical skills. The given clinical observation demonstrates the course of pregnancy and childbirth in a patient with pelvic organ prolapse of stage II according to the POP-Q classification, contains brief judgments on the management of pregnancy at the outpatient stage.

The article presents the results of recent studies on the effectiveness, safety and duration of menopausal hormone therapy (MHT). The main cardio-metabolic risk factors for cardiovascular diseases are formed in women precisely during the transition to menopause and are clearly associated with the appearance of vegetative menopausal symptoms and the development of endothelial dysfunction, which is a predictor of future serious health problems, especially cardiovascular diseases. The results of a number of epidemiological studies have shown that in women with severe climacteric manifestations, especially with hot flashes, the overall risk of developing cardiovascular diseases is increased. The need for early initiation of MHT is an indisputable truth and is not disputed by anyone, but the formed tendency to discontinue treatment in 56 years raises many questions among patients and their doctors. However, recent guidelines from the International Menopause Society state that there is no reason to arbitrarily limit the duration of MHT. This paper presents current evidence on the indications and benefits of low and ultra-low doses of MHT. In view of the high efficacy and safety of low doses of MHT, they seem to be the most acceptable starting doses of oral MHT for most women. In addition, women with early menopause should also receive higher doses of estrogens, as they are more physiological for them. The choice in favor of starting MHT in a postmenopausal woman with a low or ultra-low dose in each case should be selected individually.

Aim. To study the effectiveness of the use of Neovir (sodium oxodihydroacridinyl acetates) as immunomodulatory and antiviral drug in the comprehensive treatment of various grade cervical intraepithelial neoplasia (CIN). Study design: prospective comparative study.

Materials and methods. The study included 60 patients (mean age 34.78.2 years) with morphologically verified various grade CIN, who were received comprehensive treatment, including the use of Neovir (sodium oxodihydroacridinyl acetate) as the drug with immunomodulatory and antiviral activity, 250 mg/2 ml intramuscularly every 48 hours, 10 injections before (group 1) or after (group 2) multi-stage radiosurgical diagnostic and treatment procedure or only a similar surgical intervention (group 3). All patients underwent complete clinical, morphological and laboratory examination with monitoring for the presence of high-risk human papillomavirus (HPV) in the cervical scraping and the dynamics of peripheral blood lymphocyte subpopulations.

Results. Dynamic follow-up showed that in a month after surgery, patients who were treated with radiosurgical resection as monotherapy (group 3) had the lowest rate of complete epithelialization of the cervical stump 30.0% vs 55.0 and 65,0% in the group 1 and group 2 respectively. In this group, the proportion of patients with persistent viral infection was 1.52 times higher than in the groups where an antiviral drug was used in combination with radiosurgical intervention 35.7% vs 17.6 and 22.2% in the group 1 and group2, respectively. In 6 months, elimination of high-risk HPV in groups with comprehensive treatment reached 94.5 in the group 1 and 94.1% in the group 2 (p0.05) vs 78.6% in the group 3. The lowest number of TNK- and NK-cells was found in the group of patients who received radiosurgical treatment as monotherapy, which correlated with the highest incidence of high-risk HPV persistence after treatment in this group.

Conclusions. In patients with various grade CIN, the use of an immunomodulatory drug with antiviral activity in combination with radiosurgical intervention promotes early epithelialization of the cervix and elimination of high-risk HPV, which is confirmed by significant changes in the lymphocyte subpopulations which provide antiviral immunity.

Authors: Melo L. F. A. , Moreira A. C. L. , Camelo-Neto Gustavo
Published: August 2021

O estudo do lançamento de projéteis em diferentes níveis de ensino está baseado numa modelagem teórica simplificada, onde o projétil é abstraído em uma partícula movendo-se em duas dimensões e, normalmente, não sujeito ao efeito resistivo do ar. Neste trabalho, é apresentada uma proposta experimental simples, envolvendo a utilização de brinquedos de baixo custo, com o objetivo de implantar atividades investigativas em sala de aula, despertando uma postura crítica acerca dos modelos teóricos estudados. Como forma de demostrar o relacionamento entre a modelagem teórica-matemática e a experimentação, é realizada uma revisão detalhada de dois dos modelos teóricos existentes para o lançamento oblíquo de uma partícula: o modelo padrão sem resistência do ar e o modelo sujeito a uma força de arrasto linearmente proporcional Ã  velocidade da partícula. No primeiro modelo é utilizada a estratégia usual, utilizando-se a cinemática vetorial, no segundo, são desenvolvidas as equações do movimento a partir das leis de Newton, as quais são resolvidas exatamente. Em ambos os casos, são obtidas expressões analíticas para o alcance dos projéteis em função do ângulo de lançamento -- e do coeficiente de resistência do ar no segundo modelo. Além da comparação e discussão entre os resultados dos modelos matemáticos, é proposta uma abordagem experimental investigativa de baixo custo para o lançamento de projéteis reais, utilizando brinquedos. Nessa oportunidade, estudantes são desafiados a levantar concepções espontâneas acerca da validade do modelo matemático sem resistência do ar, ao qual foram expostos previamente em sala de aula.  Finalmente, os estudantes são apresentados aos resultados do modelo com resistência da ar, sem serem mostrados necessariamente os detalhes do desenvolvimento matemático, sendo feitas considerações a respeitos de alguns dos melhoramentos. Por fim, são apresentadas evidências acerca da eficiência da atividade investigativa na compreensão sobre o que seja um modelo matemático e sua relação com a realidade.

Published: August 2021

La población joven brasileña ha sido protagonista en las movilizaciones políticas a partir, por ejemplo, de la emergencia y expansión de los movimientos de protesta y de nuevas formas de acción política, sobre todo con el uso de tecnologías digitales. El objetivo de este artículo es evaluar la trayectoria política de representantes de la juventud nacional de 10 partidos brasileños. Para ello, se realizaron entrevistas en profundidad, entre noviembre y diciembre de 2019. A partir del material recolectado, los datos se presentan en tres ítems: i) perfil de los jóvenes entrevistados, ii) consumo de información sobre política; y iii) trayectoria y cultura política. Los resultados obtenidos apuntan a la discusión de cuatro temáticas principales: a) exclusión digital y participativa; b) acceso a la información y calidad de la democracia; c) variables de la cultura política; y, d) dimensión comunicativa y potencial de Internet como esfera pública. En el escenario actual, las tecnologías de información y comunicación pueden ser importantes instrumentos facilitadores de la movilización social, como medio o herramienta de la acción colectiva ciudadana. Así como las tecnologías de información y comunicación permiten un mayor acceso a las informaciones, también permiten prácticas online de participación ciudadana, volviéndose, potencialmente, una esfera pública virtual y, asimismo, indican los usos y las apropiaciones desarrollados por la juventud partidaria brasileña.

Published: August 2021

En décadas recientes los medios electrónicos se han vuelto parte de la vida cotidiana y, la llegada de las redes sociales en línea, ha otorgado a sus miembros la posibilidad de relacionarse y formar comunidades digitales, que hacen posible la formación de capital social. Tener una reserva abundante de capital social supone la producción de una sociedad civil densa, que se relaciona estrechamente con la participación política. Por lo anterior, el objetivo de esta investigación es encontrar la influencia del uso de Facebook en la participación política en línea. La metodología utilizada en esta investigación es cuantitativa, la cual buscó medir, mediante una encuesta con ítems en escala Likert, la incidencia entre las variables: intensidad de uso de Facebook, capital social en línea y participación política en línea. El objeto de estudio es la población de la ciudad de Culiacán, Sinaloa, México, por su alto porcentaje de usuarios de Internet en el país y su nivel de participación electoral. Como resultado, la participación política en línea mostró relación con el resto de las variables, incluso a partir de regresiones lineales se demuestra que es influenciada por el uso de Facebook. Si los sitios de redes sociales, como Facebook, influyen en la participación política en línea, al socializar información que puede contener asuntos públicos entre contactos, representan una oportunidad de dinamizar la participación política en forma física y con ello incidir en los procesos democráticos.

Published: August 2021

En el marco de la pandemia por la COVID-19, las Universidades ecuatorianas ejecutaron acciones para mitigar la emergencia sanitaria orientadas a garantizar una educación de calidad. En ese sentido, la presente investigación tuvo como objetivo desarrollar un diagnóstico, a través de un instrumento de base estructurada, para medir las competencias básicas necesarias para el ingreso a una Universidad particular del Ecuador. Este diagnóstico permitió identificar el nivel de las competencias de los aspirantes, como resultado del nivel de cumplimiento del derecho a una educación de calidad del bachillerato. Para ello se desarrolló y aplicó el instrumento de forma virtual a los aspirantes. Una vez culminado el proceso, se procedió al análisis de los resultados y su entrega. Los resultados obtenidos demuestran que los aspirantes alcanzan en promedio un nivel por debajo de la media nacional en el examen de ingreso a la educación superior (Ser Bachiller). Además, en las cuatro competencias evaluadas los aspirantes se ubican en promedio en los niveles más bajos. Esto refleja una falencia en el cumplimiento de lo establecido en la Constitución y la LOEI con relación a garantizar una educación de calidad en el bachillerato. Esto a su vez supone esfuerzos adicionales de la Universidad para equiparar estas competencias en los primeros niveles de formación y así cumplir con una educación superior de calidad, pertinente, en igualdad de oportunidades, procurando la permanencia y eficiencia terminal, reto que se acentúa en el contexto de la pandemia.
Importancia de las luchas populares, desde la Época Colonial, en la configuración del Estado-nación ecuatoriano.
Authors: Almeida Jorge
Published: August 2021

Desde un punto de vista social, el desarrollo histórico del Ecuador se enmarca en el establecimiento de un proyecto nacional hegemónico profundamente caracterizado por conceptos coloniales como la exclusión basada en la clase, la raza y el color de la piel. Esta pesada herencia influenciará de distintas maneras en la consolidación de una nación que parte desde una visión de las elites, en profunda contradicción con los sectores populares que se van desarrollando como elementos subalternos, pero que como veremos en el desarrollo de este trabajo que abarca los distintos períodos históricos del país, desde la Colonia al presente,  van también convirtiéndose en actores de su propia historia,  pugnando por alcanzar niveles de representatividad y conducción.
Perspectivas a la producción científica del Ecuador

Published: August 2021

El presente artículo surge de la necesidad de conocer con cifras objetivas los índices de escritura científica que se realizan en el Ecuador, con respecto a otros países como: Colombia, Perú, Argentina, México y España. La importancia de este estudio radica en reflexionar acerca de este tema, a partir de una revisión de bases de datos internacionales de publicación como SCOPUS, Scielo y SJR. La metodología utilizada es de carácter inductiva-deductiva y se apoya en una investigación bibliográfica, utilizando el método de observación cuantitativa. Existen indagaciones previas acerca del tema tratado, sin embargo, la mayoría no ha considerado una comparación cuantitativa de la publicaciónecuatoriana con otras naciones. Además, se ha soslayado la relación entre producción científica y políticas públicas ecuatorianas. Para solucionar la desatención a esta problemáticase consideraron normativas dadas por los organismos rectores de la calidad educativa, tales como la Secretaría Nacional de Educación Superior, Ciencia, Tecnología e Innovación (SENESCYT) y el Consejo de Aseguramiento de la Calidad de la Educación Superior (CACES) estas organizaciones fundamentan sus labores basándose en leyes como la Ley Orgánica de Educación Intercultural (LOEI) y Ley Orgánica Reformatoria a Ley Orgánica de Educación Superior (LOES). Esto permitió obtener resultados que evidencian una baja producción científica en el Ecuador, que, a pesar de su incremento en los últimos años, no ha sido representativa en relación con otros países. Por esta razón la presente investigación implica la consideración de leyes y datos cuantitativos para superar el índice bajo que presenta el Ecuador en escritura científica.

Farm is one of the largest food suppliers after agriculture. Many of the breeders do everything to improve the quality of their livestock. The usual way used by chicken farmers are by manual means such as temperature checking, and checking the availability of feed. Therefore it is necessary to create an automatic temperature monitoring and chicken feeding tool, which in this research based on IoTs (Internet of Things). It uses DHT11 sensors to measure temperature in cages, Arduino Uno and NodeMCU ESP 8266 as microcontrollers and blynk applications as temperature monitoring tools. It consists of several interconnected parts. Starting from the DHT11 sensor measuring the temperature, then sent to the microcontroller after it is processed, then sent to the blynk webserver so that it can be accessed and displayed by the monitoring application. While chicken feeding can be made easier using servo motor as a door feeder chicken that works with scheduling system, then for the availability of feed will be measured by the specified weight. If the weight reaches a number less than or equal to 400 grams, then the loadcell sensor will send a notification to blynk with the message . The result of this researchs can monitor the temperature in the cage and provide feed automatically even though it still not maximal.

Big Data is a collection of data with a large and complex size, consisting of various data types and obtained from various sources, overgrowing quickly. Some of the problems that will arise when processing big data, among others, are related to the storage and access of big data, which consists of various types of data with high complexity that are not able to be handled by the relational model. One technology that can solve the problem of storing and accessing big data is Hadoop. Hadoop is a technology that can store and process big data by distributing big data into several data partitions (data blocks). Problems arise when an analysis process requires all data spread out into one data entity, for example, in the data clustering process. One alternative solution is to do a parallel and scattered analysis, then perform a centralized analysis of the results of the scattered analysis. This study examines and analyzes two methods, namely K-Medoids Mapreduce and K-Modes without Mapreduce. The dataset used is a dataset about cars consisting of 3.5 million rows of data with 400MB distributed in a Hadoop Cluster (consisting of more than one engine). Hadoop has a MapReduce feature, consisting of 2 functions, namely map and reduce. The map function performs a selection to retrieve a key, value pairs, and returns a value in the form of a collection of key value pairs, and then the reduce function combines all key value pairs from several map functions. The results of the cluster quality evaluation are tested using the Silhouette Coefficient testing metric. The K-Medoids MapReduce algorithm for the car dataset gives a silhouette value of 0.99 with a total of 2 clusters.
APPLICABILITY OF HAUNTOLOGY TO THE STUDY OF THE ORIGINS OF SCREEN ARTS
Authors:   Russian State University for the Humanities, MARKOV ALEXANDER V.
Published: August 2021

The article discusses the possibility of making hauntology one of the methods of studying screen arts at the stage of their formation, which might make it possible to correctly interpret the use of early screen arts techniques in later cinema and television broadcasts. Hauntology is a method backed by a program of research into social life and the role of associations in maintaining stable communicative structures, which program is based on the assumption of “ghosts” as cultural actors inherently belonging to the cultural order. Based on the ideas of Jacques Derrida and Mark Fischer, going back to Sigmund Freud’s methods of studying the “uncanny” and “effect of reality”, hauntology claims that ghosts determine the modes of nostalgia and user orientation of a number of screen and visual arts, in particular, the visual principles of modern musical culture. Although hauntology researchers focus extensively on the world of ghosts in the culture of the 19th century, they limit themselves to private remarks and often optimistically presume the fact that the plot rationality ultimately triumphs over the power of ghosts. However, this contradicts both the actual history of the culture then, and the basic principles of hauntology, which asserts that ghosts cannot be fully rationalized. Therefore, the article proposes a visual-critical hauntology, which allows us to explain how visualization techniques contributed to the rationalization of ghostly existence, and how, to create the effect of reality, a screen was required as the basic method of this visualization. Vladimir Toporov’s work on the mystical prose of Turgenev provides the main source of visual-critical hauntology thus proving the need for screen projection to express the author’s position in the era under consideration. The article establishes a connection between the ghostly statuses and the need for a screen reflection mode, which provides a consistent description of psychological reality. It is pointed out that a number of literary experiments of the Victorian era require a screen medium as a basis for understanding the independent sequence of events, from the plot of internal psychological transformation in Dickens’s A Christmas Carol to the “unreliable storyteller” technique in Henry James’s The Turn of the Screw. Visual-critical hauntology, referring to the history of psychology, the decisions of directors, especially Hitchcock, indisputably proves that it is possible to cope with ghosts and rationalize them not with the help of everyday life staging, as it is usually considered, but with the help of its adaptation, which allows to apply emerging technology for creation long-term effect of reality.

The article is based on the studies by the Department for the Development and Approbation of Film Education Methods (VGIK) in the field of amateur film associations and cinema clubs. The authors profile the history of the Russian film club movement and analyze the significance of such associations for cultural enlightenment and comprehensive education of a personality. Such a survey is included in the international process of the formation of a cinephile community, who in the USSR were called nothing short of “kinomany” (movie addicts). A hundred years of experience of Russian film education, in the forms of both spontaneous amateur one and complex state one, is considered as a source of methods and best practices to be implemented in modern media education. The article also explains the influence of film clubs and their repertoire on the distribution and popularization of cinema works, especially on the so-called festival and “shelved” films, limited in release then and now becoming a battleground between commercial and artistic priorities of the filming process. The text contains stories and descriptions of participants in the film club movement: the founders of associations, curators and critics. Their interviews make it possible to imagine a three-dimensional picture of the life of cinema lovers’ communities. The main milestones in the history of the film club movement in the USSR and in the world are traced: the formation in the 1910s–1920s, the decline in the 1930s–1940s, the revival of the international festival movement abroad after World War II, and in Russia—during the perestroika, the crisis of the 1980s–1990s, the creation of the Cinema Club Federation, attempts to revive the Friends of Soviet Cinema Society, and modern trends related to the film club work in the context of international cooperation, which was initiated by the VI World Festival of Youth and Students. The Soviet experience is studied in correlation not only with the strengthening in Western Europe of such phenomena as film clubs and film lovers’ associations, but also with the formation of specialized art cinemas and the experiment of the cinema club network, which is predicted to play a special role in the post-pandemic era. Among other things, the authors’ attention is focused on the delicate balance, that accompanied the entire history of the film club movement: the balance between initiative of the people, a spontaneous mass movement, and state efforts to organize and structure this process, between the desire for creative freedom and strict censorship of the elite. The authors consider the domestic and foreign cinema club experience as an opportunity to distribute works of the Russian cinema art among the most interested audience and to establish a system of limited cinema club distribution, which would bring originators and the public closer together.

The city of Karawang is famous as a city of rice granaries. As a city of rice granaries, the city of Karawang is assigned a surplus of unhulled rice of 1.5 million tons. This causes a large number of rice husks to become waste from the mills. With the knowledge and skills of farmers who are still minimal in utilizing rice husk waste, most of the rice husk waste by farmers is only thrown away or burned so that it can cause environmental pollution around the disposal of rice husk waste. One way to utilize rice husk waste is to process rice husk waste into animal feed. An alternative to solve this problem is by making a fish pellet printer that is used to produce fish pellets using rice husks as the basic ingredient. This fish pellet printing machine is made with the aim of utilizing rice husk waste which is only thrown away or burned by farmers so that rice husk waste can become a high-value product. In this study, data collection techniques were carried out by studying literature and conducting experiments on fish pellet making machines. After that, the design of the shape was carried out then continued with the manufacture / assembly of components of the fish pellet printing machine and finally the testing of tools / machines with parameters was designed and equipped with an electric motor 250 watts 220 volts 1400 rpm so that it can be used in industry. at home, this electric motor aims to act as a screw driver which is assisted by a WPA gearbox with a ratio of 1:30 so that the rotation obtained is not too fast, the rotation speed can be adjusted by the amount of pulley used so that it can be in accordance with your wishes. With these conditions, it will greatly assist producers in carrying out and speeding up the process of grinding fish pellets.

Motorbikes are widely chosen by the public as a mode of transportation in modern times, one of which is the automatic scooter type motorcycle. Visually, the matic scooter type motorcycle components have a nice and attractive shape, but this shape does not necessarily guarantee its safety. Not a few of these components have failed (broken) as happened to the footrest. Footrest is a component of a motorcycle vehicle that functions as a footrest for motorcycle passengers. Every different type of motorbike, the footrest shape is also different. The purpose of this study is to design a footrest design and analyze it with the help of software to obtain a footrest design that has a high safety factor value. The design of the motorcycle footrest design produces 3 different designs. The three designs were analyzed using the Autodesk Inventor 2017 software stress by providing a static load of 20 Kg and 90 Kg. From the analysis, the minimum safety factor value obtained from each footrest design against a load of 20 kg in design 1 is 13.42, design 2 is 5.7, and design 3 is 7.93. While the minimum safety factor value generated from each footrest design against a load of 90 kg in design 1 is 2.98, design 2 is 1.27, and design 3 is 1.76. Based on the results of the safety factor analysis carried out, the three designs are safe enough to withstand loads of 20 Kg and 90 Kg. But design 1 is safer because the resulting value of the safety factor is higher than the three designs, which is 2.98 to withstand a load of 90 Kg.

The purpose of this study was to observe the combustion of diesel fuel combined with the percentage volume of water and emulsifier, namely alkyl benzene sulfonic acid (ABS). The emulsion fuel composition used in this experimental study is a mixture of diesel fuel, emulsion and water. The composition of the emulsion fuel is designed according to the percentage of water volume and the emulsifier in diesel fuel with a variation of the percentage of 10%, 20%, and 30%. The parameters observed were combustion flame temperature, combustor annulus wall temperature, hot gas temperature, air fuel ratio (AFR), heat loss, and flame shape from differences in the composition of the percentage volume of emulsion fuel. In this test using Combustion Laboratory Unit C 491. The results showed that the heat absorbed due to cooling (Qa) in the AFR stoichiometry of diesel fuel (diesel) 26.334 kW was smaller than emulsion fuel (30.096 kW), so the use of emulsion fuel on the Burner Combustion Laboratory Unit C 49 is very suitable. The shape of the flame produced by the combustion of emulsion fuel is short, turbulent, and covered in water vapor.
