Authors: Wahyudi Dicky , Laturrakhmi Yun Fitrahyati
Published: November 2023

This research aims to identify the coach roles in youth football coaching at ASIFA (Aji Santoso International Football Academy) through an instructional communication framework. This research uses an approach method with two data collection techniques which include: Interviews with ASIFA coaches, and participant observations at ASIFA football coaching. The data analysis technique combines interactive analysis models and the theory of instructional communication. The results of this study showed that the role of coaches at ASIFA in the instructional communication framework can be classified into two types, namely: 1) Coach as communicators-instructors; and 2) Coach as communicator-facilitator. The difference in type has implications for the communication approach used by the coaches, which is mapped into a rhetorical approach and a relational approach. However, the type of coaches and the communication approach used by the coaches has a relationship with the coaching context that occurs. This research contributes to the formulation of an instructional communication quadrant model that can be carried out by coaches in youth football coaching.
La denominación o razón social de compañías mercantiles. Análisis y diferencias con el nombre comercial en el Ecuador
Authors: Villamar Segura Ruth , Carrión Márquez Carlos
Published: November 2023

Algunas especies de sociedades mercantiles tienen que reservar su denominación o razón social ante la plataforma informática de la Superintendencia de Compañías, Valores y Seguros, por ser el organismo de control competente. Sin embargo, las compañías que buscan posicionarse en un determinado mercado podrán, al mismo tiempo, utilizar un nombre comercial que les permitirá distinguirse en las actividades que vayan a emprender. Para lo cual, deben seguir el debido proceso administrativo el Servicio Nacional de Derechos Intelectuales en cuanto a su registro, tratándose de un acto jurídico diferente al efectuado al momento de constituirse y registrarse como compañía. En ese contexto, es importante precisar que la denominación o razón social de una compañía no es lo mismo que su nombre comercial, lo cual no constituye un elemento excluyente al momento de empezar con las actividades comerciales, pero sí es importante obtenerlo ya que garantizará su propiedad y surtirá efectos erga omnes frente a cualquier uso indebido. Finalmente, los resultados obtenidos en esta reflexión buscan abordar, de forma integral, cuáles son los procesos a identificar respecto al proceso de registro de una denominación o razón social y - por cuerda separada - conocer todo lo necesario sobre el nombre comercial, como propiedad intelectual, y su importancia en las actividades mercantiles.

La virtualización de la educación como consecuencia de la propagación del covid- 19, dio paso a la generación de diversas situaciones, que permitieron evidenciar entre otros aspectos, la relación de los docentes con la tecnología. El desarrollo del proceso de enseñanza en entornos virtuales por más de diecisiete meses, ha permitido identificar no solo las falencias presentes en el sistema educativo ecuatoriano, sino también en la formación y motivación del profesorado frente a la tecnología, específicamente con relación al dominio de las competencias digitales básicas para desarrollar la labor docente. Para realizar el levantamiento de datos, se solicitó a un grupo de 61 docentes de educación básica y bachillerato que, mediante un vídeo de duración máxima de un minuto comparta una anécdota que le haya marcado, de la experiencia impartiendo clases en la virtualidad. Una vez receptados y analizados los videos, se clasificó la información obtenida logrando establecer tres categorías de experiencias: relacionadas con la tecnología, relacionadas con el entorno de enseñanza y relacionadas con la actitud de los estudiantes, además los resultados permitieron reconocer las emociones generadas en los docentes a partir de la experiencia vivida.
Justicia, en las garantías jurisdiccionales
Authors: Domínguez Vásquez Paolo Andrés
Published: November 2023

El tema de las garantías jurisdiccionales, se ha visto desarrollado y evolucionado en el Ecuador por mérito de la Constitución de la Republica, puesta en vigencia desde el año 2.008, ya que la configuración que realiza la carta magna en su artículo 1, determina que es un estado constitucional de derecho y justicia social, los que nos lleva a identificar y visualizar la transversalidad en todo nuestro ordenamiento jurídico, de lo constitucional, más allá de ser la normatividad supraconstitucional, en todo aspecto jurídico, legal y administrativo, debe de respetarse esa superioridad constitucional, las misma que no solo basta, con un simple hecho de respetar. Sino que también en toda decisión que se adopte, es decir se tome y dicte mediante sentencia o resolución, se debe hacer bajo la supervisión y alineamiento de lo constitucional, las decisiones que guarden relación cumple con esta característica, lo que lleva a pensar, que se actúa conforme a la visión del estado constitucional. Esto no significa que la decisión por esta acorde a los parámetros constitucionales, no afecte o genere la violación o vulneración de los derechos del ciudadano o colectivo, podría hablarse del derecho constitucional vulnerador, lo que sería un sinónimo ya en justicia ordinaria a lo que se conoce como derecho injusto. Dándonos la posibilidad constitucionalmente hablando de ir en busca de la justicia, a través de la activación de las garantías jurisdiccionales más comunes, con la sentencia, en que se reconozca nuestro derecho fundamental como transgredido, junto con la reparación integral sea esta materia o formal, o ambas a la vez, se configura o no, alcanzar la justicia, ya que entendidos en el tema sostienen que no, por cuanto con el cese o el fin de la violación de dicho derechos, se vuelve al estado natural de nuestros derechos antes de ser transgredidos.

middle Iraqi provinces
Authors: Hamzah Mosa Ahmed , Mohammed Badawi Naseir , Salah Hussein Zaid , Jassim Mohammed Ahmed
Published: November 2023

Equine infectious anemia (EIA) is a viral infection that affects Equidae as a persistent infection. Infected horses usually develop a systemic disease with mild
clinical signs such as irregular fever, weight loss, anemia, and weakness. The
study was the first molecular record of the EIA viruses in horses in Iraq. In total,
72 blood samples (30 horses and 42 donkeys) were selected with history and
signs of anemia. The study was conducted in central Iraq (Babylon, Karbala, and
Al-Dawinih provinces) from 2015 to 2017. Then, primer design and molecular
identification of the gag gene of the EIA virus were performed. The results
showed that EIA virus infection rates in horses and donkeys in Iraq's middle regions were 16.66% and 0%, respectively. The DNA sequences of two positive
EIA virus samples revealed that isolates have 271 nucleotides under accession
numbers MN861108.1 and MN861109.1, respectively. The phylogenetic analysis
revealed that Iraqi isolates were clustered in different clades and revealed 83.1–
100% identity with EIAV world isolates in the NCBI. This study was the first
molecular record of EIA viruses in Iraq. The study indicated that the gag region
was an essential target for EIAV detection.

Aspectos ontoepistemológicos de los debates actuales en torno al cuerpo sexogenerizado en Argentina
Authors: Suárez Tomé Danila , Maffía Diana H.
Published: November 2023

Ofrecemos un análisis de los aspectos ontoepistemológicos de los debates actuales sobre el cuerpo sexogenerizado en Argentina. Con herramientas teóricas de la fenomenología feminista, la epistemología feminista y los nuevos materialismos feministas analizamos, por un lado, la manera en que el Estado argentino comprende el cuerpo sexogenerizado y, por el otro, una serie de afirmaciones en los discursos transexcluyentes que conflictúan estas discusiones. Buscamos despejar el terreno conceptual del debate feminista para determinar qué posturas nos permiten avanzar y cuáles nos hacen retroceder. Concluimos que, mientras que las nociones en la ley de identidad de género están amparadas por el conocimiento feminista actual, los discursos transexcluyentes que cuestionan su contenido representan un marco de comprensión ontoepistemológico patriarcal.

Authors: Sony Mekala , Jayashree Dr. P. R.
Published: November 2023

Stress-strength reliability is an important concept in reliability analysis, quantifies the probability that the strength of a system surpasses its applied stress. This paper focuses on the reliability analysis for exponentiated exponential distribution strength variable and the exponentiated Weibull distribution stress variable. The study explores the estimation of the parameters in stress-strength reliability model using maximum likelihood estimation and Bayesian estimation. In particular, the Bayesian estimator of stress-strength reliability is obtained by utilizing Lindley’s approximation by considering both linear exponential loss function and squared error loss function for informative and non-informative priors. A comprehensive simulation study is conducted and the performances of estimators are compared using mean squared errors. The stress-strength reliability for real datasets is also investigated for real-time data sets.
Employing LSTMs for Music Remixing

Published: November 2023

Abstract: The Main Idea was to generate a mixed music from solo musical instrument. For carrying out this task there are various subtask to be carried from data collection to preprocessing the data to make it compatible with the Long Short Term Memory Recurrent Neural Network (LSTM RNNs) model. So, Music mp3 media was collected from melody loops and each one was trimmed down to 30 seconds. Conversion tool was used for segregating the Music into four different mp3 media file i.e. Bass.mp3, Drums.mp3, piano.mp3 and others.mp3. We prepared different models for accomplishing the task to get good results; therefore we preprocessed and transformed the data every time for the new Model architecture. We started with developing the most basic model architecture using Deep neural network (DNNs) and LSTM RNN, and this model architecture was so basic that it did not captures the dependencies within the music , although results was fine but music it generated does not make any sense. Than we tried experimenting by developing different model architectures which generates sensible music and we developed more complex architectures using LSTM RNNs which have the potential to make good results. But there is one disadvantage of it that it takes very long time to get fully trained. In order to reduce the training time and utilizing our resources properly we divided our model into 4 sub-models each for generating music of different musical instruments , These sub-models were trained in parallel on different Google Colaboratory notebook and their best model weights were stored for Reusing them for inference. These all were put into single notebook for predictions and each of these predictions are then combined to make the desired result

Published: November 2023

In order to achieve quality learning in accordance with the aspirations and the fourth goal of SDGs, teachers need to create learning that is complete and in accordance with the needs of students. This complete and appropriate learning can be demonstrated by the teaching modules used by the teacher. In fact, teachers still encounter problems in compiling teaching modules that suit the needs of students in the current era of digital technology. This obstacle is also experienced by high school English teachers in Sidoarjo. One of the challenges is the lack of innovation in using and implementing information and technology-based English learning media. Therefore, with this community service, the authors aim to increase the high school English teachers' innovation through training on teaching module development with EdPuzzle integration. The success of this program was measured from a questionnaire filled out by the teachers. As a result, teachers who previously did not know what EdPuzzle was were finally able to create and implement it in class. They argue that digital media such as EdPuzzle is very useful for teaching and learning English. Thus, this community service has been carried out properly and succeeded in achieving the planned goals.

Published: November 2023

The development of online markets in Indonesia that sell imported goods at low prices has caused many MSMEs to go collapse. To accelerate the Sustainable Development Goals, especially achieving the goal of "a country with no poverty, no hunger, creating decent jobs and economic growth as well as a healthy and prosperous country," MSMEs need to be protected from these problems. This study aims to analyze the prospects for the development of online shopping and its impact on MSMEs and propose improvements to marketplace governance. Method research includes interviews, secondary data studies, literature reviews, and meta-analyses. Research results show that online shopping is a need for future society; the marketplace is increasing in terms of numbers, consumers, and transaction value. The number of MSMEs experiencing collapse has increased due to the inability to compete with marketplace players. It is necessary to improve marketplace governance through regulations to protect MSMEs. Current laws only protect consumers, not yet protect MSMEs. Through marketplace governance, it can empower MSMEs to overcome and prevent poverty and hunger, create decent jobs and economic growth, have a healthy and prosperous life, and accelerate the achievement of the SDGs.

Published: November 2023

Objective: People living with HIV (PLWH); can be especially vulnerable to the effects of SARS Co V 2 and COVID 19. In this study, we evaluate the factors associated with acquiring COVID 19 and the severity of the infection among PLWH. Materials and methods: Through a case-control study nested in a cohort, where cases were PLWH diagnosed with COVID 19; and controls were PLWH without the infection, 476 people were evaluated between May 1, 2020, and February 28, 2021. A univariate analysis was performed with the variables considered candidates. Binary logistic regression models were conducted for the COVID 19 outcome, and among those diagnosed with the infection, regression models for the outcome of hospitalization vs. outpatient treatment. Results: Among 238 PLWH diagnosed with COVID 19, receiving integrase inhibitors p < 0.001 (CI 95% 0.27,0.72) or protease inhibitors p 0.034 (CI 95%0.42,0.97) within their antiretroviral regime, was associated with a lower probability of developing COVID 19. 196 (82,35%) of the 238 cases received outpatient treatment, and 42 (17,64%) required hospitalization. In this case, being older than 50 years p < 0.001 (CI 95% 1.8,9.64) and having obesity as a comorbidity p 0.017 (CI 95% 1.34,17.93) increased the possibility of requiring hospitalization, while receiving antiretroviral treatment or having received vaccination against influenza, decreased the likelihood of this outcome. Conclusions: There are still many questions regarding whether there is a differential risk of acquiring COVID 19 among PLWH. Antiretroviral treatment with inte­grase or protease inhibitors; was associated with a lower probability of developing the co-infection. Some factors related to comorbidities, such as older age and obesity, draw attention to possible risk factors for hospitalization in this population. Discussing the feasibility of new studies with proposed causal hypotheses that allow directing the research designs toward a more precise answer to these questions is essential

Jānorāda, ka nevienā brīdī tās visas trīs nav bijušas aktīvas vienlaikus. 20. gadu vidū paralēli darbojās LKB un LSK, apvienojot atšķirīgu paaudžu un darbības virzienu mūziķus ap divām personībām – Ernestu Vīgneru un Jāzepu Vītolu. Dažādu apstākļu dēļ 30. gadu sākumā tika dibināta NKB – tās darbība ātri vien apsīka, saskaroties ar LSK konkurenci. Biedrības savstarpēji nesadarbojās, bet konkurēja par biedru piesaisti, finansējumu, ietekmi, kā arī LSK un LKB gadījumā – par mūzikas žurnāla izdošanu.

A research was conducted to create car bumper materials using natural kelakai plant fibers combined with a catalyst and resin as a binding agent in the composite. The main goal of the study was to examine the tensile strength of the kelakai fiber composite with different catalyst variations and assess the impact of these catalyst changes on the bumper material's tensile strength. The composite materials were prepared in three test specimens with catalyst compositions of 2,5%, 5%, and 7,5%, respectively, based on a 20 mL resin composition. These samples underwent tensile testing using a Universal Testing Machine (UTM). The results revealed that the tensile strength of the kelakai fiber composite increased with higher catalyst percentages. At 2,5%, 5%, and 7,5% catalyst compositions, the tensile strengths were measured as 0,37 N/mm2, 0,41 N/mm2, and 0,47 N/mm2, respectively. Additionally, the elongation values for the catalyst portion are 1,11%, 2,22%, and 3,89% and the Young's modulus values are 0,33 N/mm2, 0,18 N/mm2, and 0,12 N/mm2, respectively. The study demonstrates the significant influence of catalyst variations on the tensile strength of the kelakai fiber composite.

Drilled well water at the Ar-Rahmat Mosque in Manunggal Village, Labuhan Deli District, Regency Deli Serdang, North Sumatra Province, has a color that tends to be yellow and cloudy. From the test results, it was found that the turbidity level in the drilled well water reached 35.3 NTU and the iron (Fe) content reached 1.679 mg/L. This shows that the borehole water does not meet clean water standards according to PERMENKES RI No.32 of 2017, namely with a maximum turbidity level of 25 NTU and a maximum iron (Fe) content of 1.0 mg/L. There is one way to purify borehole water by using moringa seeds and tamarind seeds in the coagulation and flocculation processes through the centrifugation method. This study aims to determine the most optimal seed composition in purifying well water. The mass variations used in this study were moringa seeds and tamarind seeds each with a mass of 0.08 grams and 0.09 grams. In this study, the results of the most optimal seed composition for purifying borehole water were tamarind seeds at a mass variation of 0.08 gram with a turbidity value of 0.53 NTU and a value of iron (Fe) content of 0.0087 mg/L. This shows that the drilled well water that has gone through the water purification process meets the PERMENKES RI standard No. 32 of 2017.

This study aims to analyze the mechanical and thermal properties of water hyacinth fiber-based composite materials as an alternative to environmentally friendly packaging materials. This composite material is produced by mixing water hyacinth fiber with a natural polymer matrix that can decompose easily. Manufacturing methods include mixing, pressing, and thermal treatment processes. The mechanical properties of composite materials, including tensile strength and resistance to deformation, are tested using tensile tests and hardness tests. Thermal analysis is carried out through thermogravimetric tests (TGA) to identify the thermal stability and decomposition of the material. The results showed that the water hyacinth fiber-based composite materials had fairly good mechanical properties in certain mixture compositions, although they were not as strong as composite materials using synthetic fibers. However, this material shows potential in packaging applications that do not require extreme mechanical strength. The mechanical properties of the water hyacinth fiber composite produced lead to the fulfillment of the need for use as packaging, which is light, flexible and not easily broken. The thermal properties of the composites show faster decomposition compared to synthetic fiber based composites, but are still within the acceptable range for single-use packaging. With its environmentally friendly properties, this composite material can be an attractive alternative to reduce the use of plastic in the packaging industry. Nonetheless, improvements in manufacturing processes and material formulations are still required to improve their mechanical and thermal properties and maintain packaging durability under diverse usage conditions.

A research has been conducted to help the medical staff in the hospital. The purpose of this study is to calculate and regulate the infusion flow rate of the infusion into the patient's body. This research uses an experimental method. The liquid released from the infusion is converted into droplets, which are then detected by the LM393 optocoupler sensor, which consists of three sensors arranged around the detection area by emitting infrared light through a transmitter to detect the shadow of the droplet so that the signal is received by the receiver of the optocoupler sensor. Which is processed with the Arduino Uno microcontroller. The Arduino Uno provides the results received from the sensor and coded using the Arduino IDE software to be displayed on a 16x2-character Liquid Crystal Display (LCD). The sample used in this study was Sodium Chloride (NaCl). The calibration tools performed were droplet sensor test, servo motor test, and Real Time Clock (RTC) DS3231 module test. The results of the detection in the droplet sensor configuration showed a high degree of accuracy, with an error value of 2.414%. so that this research can be implemented in the detection and appropriate management of infusion flow rates. The current testing being carried out is still on a laboratory scale. However, in the future, this system can be developed to monitor infusions in real-time over a longer period of time and using more complex data processing functions.

Students are inseparable from their cultural context. This study examined the difference of ethnic identity and subjective well-being between students with Javanese and Chinese ethnic backgrounds, based on two different previous research results. The research design was a comparative quantitative study with two independent samples. The study involved 101 high school students (71 ethnic Chinese students and 30 Javanese students). Sampling technique used was purposive sampling, based on the criteria decided by the researchers. The data collection tools used were the ethnic identity scale and subjective well-being scale. The analysis techniques used were percentage descriptive analysis and independent sample T-test analysis. Data showed a significant difference in ethnic identity between Javanese and Chinese students (t=2.011, p<0.05). Javanese students have a higher level of ethnic identity than Chinese. In addition, this study showed a difference in subjective well-being between Javanese and Chinese students (t=2.197, p<0.05). The results of this study have implications for counseling services to support subjective well-being, especially for ethnic Javanese and Chinese students.

The aim of this study was to examine the companionship of psychological hardiness, narcissism, and perfectionism on depression tendency among undergraduate students in Oyo State, Nigeria. A qualitative research design by means of correlational approach was adopted to pilot the study. A total of one thousand and eighty-six (1086) participants selected through a process of stratified random sampling from Oyo State, Nigeria, partook in the study. Four measuring instruments: Depression Proneness Rating Scale-11 (α=.77), Dispositional Resilience Scale (α= .73), Almost Perfect Scale-Revised (α= .87), and Pathological Narcissism Inventory (α= .91) were used to garner data. Collected data were subjected to analysis through Pearson Product Moment Correlation and Multiple regression model. Findings revealed that a combination of predictor variable accounted for 42% of the total variance in depression tendency (R2=.417; F (5,1080)= 154.768; p<.01). Independently, psychological hardiness (r=-. 404; β-.236; t= -9.486; p<.01), Normal Perfectionism (r= -.370; β= -.355; t=-12.530; p<.01), and narcissistic grandiosity (r= .238; β=-.213; t= -7.532) yielded anti correlational relationship with depression tendency. However, the relationships of Narcissistic Vulnerability (r=.282; β=286; t=9.866; p< .01) and neurotic perfectionism (r= .238; β=.278; 10.031; p<.01) with depression tendency yielded positive prediction. The study outcomes were discussed, and the studied variables were recommended to be considered while diagnosing depression symptoms among undergraduate students.

The study aims to quantify the effect of Dufour number, on flow patterns
and heat transfer rates in the exponentially accelerated vertical plate
with MHD flow and chemical reaction. The unsteadiness of the flow
suggests that time-dependent changes in velocity, temperature, and other
relevant parameters are considered. MHD further complicates analysis
with the electromagnetic interactions between the fluid and the field.
The fluid, be characterized as a gray, absorbing/emitting radiation
medium, indicating that it absorbs and emits thermal radiation but does
not exhibit scattering behavior. Set of partial differential equations
are then resolve using FEM. Graphical results are then discussed.
Profiles vary with different, Dufour number, radiation, or
temperature-dependent heat source/sink parameter. By varying the values
of these governing parameters, on the skin-friction coefficient, Nusselt
number, and Sherwood number are also analyzed.
Joint Space-Ground Multi-Beam Coordination for LEO Satellite Systems

Published: November 2023

In traditional configurations where Low Earth Orbit Satellites (LEOs)
are used in conjunction with ground multi-antenna terminals to create a
virtual Multiple Input Multiple Output (MIMO) system, the high-speed
mobility of LEOs results in an unstable MIMO system topology, which
consequently affects the stability of system capacity. This paper
introduces two space-ground cooperation modes to enhance the stability
of MIMO system capacity. The first method optimizes channel capacity by
appropriately allocating the beam power of relay stations, allowing
relay stations to achieve transparent forwarding through satellites. The
second method involves rotating the angle of the user’s receiving
antenna to counteract channel variations caused by changes in satellite
positions. Simulation results indicate that both methods can effectively
improve the minimum channel capacity, with transparent forwarding
offering an enhancement of approximately 22.7%, while the rotational
antenna approach can achieve a performance gain of at least 36.3%, even
under limited rotation angles.
