Modelo de endomarketing para mejorar la satisfacción y el sentido de pertenencia del docente universitario
Authors: Duque Cardona Mauricio
Published: October 2024

Objetivo: proponer un modelo de endomarketing con el fin de mejorar la satisfacción y el sentido de pertenencia entre los docentes de una universidad privada en Colombia.Diseño/metodología: fue de tipo exploratorio, con un enfoque mixto, cualitativo y cuantitativo, por medio de encuestas, entrevistas y focus group.Resultados: dentro de los resultados más relevantes se evidenció que existen diversos niveles de satisfacción en los docentes de una institución, en cuanto a lo laboral, emocional, económica, entre otros. Hay diferencias entre lo que piensan la Vicerrectoría Académica y los decanos y profesores sobre cómo la institución motiva a su personal docente. Por otro lado, se observó que es necesario que la institución trabaje para reducir la rotación docente.Conclusiones: se concluye que las variables que más influyen sobre la satisfacción del docente son la autonomía, el salario y las horas asignadas para preparar clase, calificar y desarrollar otras actividades que apoyan a la docencia. No se evidencia concordancia en conceptos como la percepción de los valores, el desarrollo de competencias, la comunicación, la motivación o el clima laboral entre la Vicerrectoría Académica y los decanos. Los docentes describen la universidad ideal como aquella que apoya la investigación y los procesos de formación, que brinda autonomía, estabilidad y condiciones adecuadas para el desarrollo personal y profesional del profesor.Originalidad: este artículo ostenta un estudio que aporta una perspectiva innovadora porque aborda la totalidad de la población docente y los directivos encargados de su coordinación y, además, tiene un enfoque integral que combina métodos cuantitativos y cualitativos. La propuesta del modelo llena un vacío en la literatura, dado que, no se identificó otro estudio que propusiera un modelo de endomarketing para docentes.

Published: October 2024

Crowdfunding platforms are seen as potential solutions to facilitate disintermediated giving, where people can go directly to the public for help with their difficulties. Although disintermediation is widespread and active in the crowdfunding industry, the fiercely competitive environment, combined with concerns about personal data use and unethical conduct, has resulted in an enormous number of campaigns failing. Therefore, it is crucial to investigate factors that influence contributors’ intention to participate in the crowdfunding platform. Using a self-administered survey, this research collected data from 339 individuals with initial knowledge of crowdfunding activities. The results of hypothesis testing indicate that gamification has a direct positive impact on affective user experience and trust in the platform but insignificantly affects donation intention on a crowdfunding platform. Interestingly, the mediating role of affective user experience and trust are established. The results lead to the discussion that gamification alone not directly impact donors' intentions to contribute on crowdfunding platforms, it significantly influences intention when mediated by affective user experience and trust in the platform. The substantial contribution of the relationship between gamification and trust in the platform, emphasizing the importance of user experience as a key precursor to positive behavioural intentions in online and gamified environments.

Published: October 2024

Muslim-minority countries have emerged among the largest exporters of halal products for the Muslim market and received significant numbers of inbound Muslim travellers. The global nature of the halal industry value chain calls for a thorough understanding about halal, particularly in the context of Muslim-minority countries. To gain this understanding, a systematic literature review was conducted to explore the themes of halal research in Muslim-minority countries. A total of 22 empirical research articles were analysed based on a review protocol adapted from ROSES. The articles were sourced from the Scopus and Web of Science, with Google Scholar as a supplementary database. The study generated five main themes that synthesise the scholarly knowledge about halal in the context of Muslim-minority countries at the consumer, organization, and institution levels of analysis. The findings illustrate the lack of understanding about halal among the industry players and consumers, as well as the lack of central governance and policymaking within the halal industry in Muslim-minority countries. Based on the findings, the study provides future direction for research and practice.

Published: October 2024

In the era of the 4th industrial revolution, geospatial information has become essential for improving processes and enhancing task performance across the value chain, benefiting sectors such as agriculture, transportation, and logistics. Despite the widespread adoption of geospatial technology, understanding how to manage its adoption is crucial as technology continually evolves. This study aims to elucidate key aspects of managing the adoption of geospatial information and technology through a case study approach. The research involves interviews with Chief Executive Officers (CEOs) and directors from three different industries in Malaysia—agriculture, logistics, and transport—that utilise geospatial technologies. Thematic analysis of the interviews revealed four main themes: managing expectations of adoption, addressing factors of nonadoption, overseeing interactions in the adoption process, and ensuring the immersion of the technology. These findings provide valuable insights into the challenges and strategies for adopting new technologies, particularly those that transform traditional operations into technology-driven practices. The study’s evidence underscores the importance of effective management in fostering the growth and economic expansion driven by geospatial technology.
Estrategias basadas en la caja de polinomios que disminuyen dificultades en el aprendizaje del proceso de factorización de polinomios con coeficientes enteros
Authors: Montenegro-Tobar Carlos Andrés , Solarte-Chincha David Armando , Soto-Agreda Oscar Fernando
Published: October 2024

La transición de la aritmética al álgebra acarrea dificultades en los estudiantes debido al cambio en el nivel de abstracción superior que tiene el álgebra respecto a la aritmética, ya que se encuentran con conceptos donde deben aplicar conocimientos previos de diferente índole y es aquí donde el estudiante se enfrenta a diversas situaciones de inseguridad, desconfianza, temor asimismo y a lo desconocido. El objetivo de la investigación fue aportar elementos de reflexión para el aprendizaje de la factorización mediada por el uso de la caja de polinomios como herramienta didáctica. La metodología se enmarcó en el enfoque cualitativo, empleando un diseño metodológico de investigación acción, utilizando técnicas como cuestionarios y observación para identificar las dificultades en la resolución de ejercicios de factorización en estudiantes de noveno grado, se diseñaron talleres centrados en la herramienta caja de polinomios para abordar la factorización de manera innovadora y se evaluó finalmente con un postest. Los resultados de la investigación indicaron que las dificultades más comunes de los estudiantes radicaban en la simplificación de términos, la identificación de factores comunes y la aplicación de propiedades de la factorización, lo que a menudo conducía a respuestas incorrectas. Los hallazgos obtenidos en cada etapa de la estrategia didáctica reflejaron el impacto positivo de la caja de polinomios en el proceso de aprendizaje, desde la familiarización con la herramienta hasta la aplicación de procedimientos algebraico-geométricos, se observó cómo los estudiantes mostraron una mejora en su comprensión y habilidades en la factorización de polinomios, concluyendo que las herramientas tecnológicas resultan valiosas para mejorar la enseñanza y el aprendizaje de conceptos matemáticos abstractos.
Estrategias de resolución de problemas de estructura multiplicativa en educación primaria
Authors: Linares-Beltrán Leidy Julieth , Fúneme-Mateus Cristian Camilo , Jaimes-Contreras Luis Alberto
Published: October 2024

Este artículo examina las estrategias que utilizan algunos estudiantes de educación básica primaria para abordar problemas de estructura multiplicativa, incluyendo isomorfismo de medidas, comparación multiplicativa y producto de medidas. La investigación utilizó una estrategia metodológica cuantitativa, empleando un cuestionario que contenía ocho problemas que involucraban números naturales para evaluar tanto las tasas de éxito de los estudiantes como las estrategias que empleaban. Los resultados revelan que los estudiantes mostraron un menor nivel de éxito cuando se enfrentaron a problemas que implicaban producto de medidas, en gran parte debido a su dificultad para reconocer la estructura uniforme subyacente a estos problemas. Aunque los algoritmos resultaron ser la estrategia predominante entre los estudiantes, el estudio también identificó el uso de diversas estrategias alternativas, que variaban en función de la magnitud de las cantidades implicadas en los problemas. Esta investigación pone de manifiesto la necesidad de mejorar los métodos de instrucción para ayudar a los estudiantes a comprender mejor y aplicar estructuras coherentes de resolución de problemas en distintos tipos de problemas multiplicativos.
Private commercial banks and economic growth in the emerging market: An econometric overview
Authors: Tasneem Sara , Ahmad Shamim
Published: October 2024

Economic growth is the single most contributory matter in the economic development process. Behind the satisfactory growth rate, the financial system of Bangladesh has contributed. In the economic growth of a country, the banking sector plays a significant role (Alam et al., 2021). In the decade of the 1980s, the banking sector started to contribute under private ownership and Bangladesh watched economic progress from the median of the decade. The simultaneity of phenomena implies that the development of banking sector under private ownership promotes economic growth (supply-leading hypothesis) while the acceleration of economic growth necessitates the development of private banking sector (demand-following hypothesis). Hence, the study aims at the detection of supply-leading or demand-following hypothesis regarding the relation between the functions of private commercial banks (PCBs) and economic growth in Bangladesh. The study has applied the Granger causality test to detect the hypothesis. The development of PCBs and economic growth reinforce each other. To develop the PCBs, recent irregularities should be eradicated. To develop the economy, all the impediments of real sectors should be addressed.

La indagación en la clase de Matemáticas, investigación con base en la práctica
Authors: Uzuriaga López Vivian Libeth , Gallego Cortés Geoffrin Ninoska
Published: October 2024

La matemática está presente en la vida de cada persona, en la cotidianidad, en los objetos, en los animales, en los espacios, en todas partes. Es por ello, que el interés por mejorar la calidad de las prácticas en matemáticas, requiere mayores esfuerzos para cualificar a los docentes, y poder superar dificultades que se viven en el aula. ¿La matemática será sólo números y algoritmos?, ¿se aprende en matemáticas por medio de la repetición de ejercicios?, ¿brindar a los docentes directrices metodológicas fortalece sus prácticas pedagógicas?, ¿se apropian los docentes del saber matemático para ser enseñado?, ¿reflexionan respecto a sus procesos y productos de enseñanza?, ¿propenden por espacios de innovación en su quehacer matemático? Estos y otros cuestionamientos rondan por la cabeza de personas y entidades preocupadas por los procesos que se están desarrollando en las aulas, respecto a la enseñanza de las matemáticas. Repetir, transcribir, hacer solo ejercicios, escuchar únicamente al docente, a partir de lo que propone un libro escolar, genera un proceso memorístico y agotador para los sujetos involucrados, ¿se logrará con ello un aprendizaje que trascienda del aula de clase al entorno y vida de los estudiantes? Los docentes son gestores de espacios y ambientes adecuados, en búsqueda de la obtención de mejores resultados en los procesos que se emprenden con los estudiantes. Es por ello, que esto invita al docente “...a seguir transformando su práctica, modificar sus creencias sobre lo que representa abordar la asignatura; le implica dejar de lado la postura rígida y cuadrada, en la que se sostiene un riguroso control de lo que acontece en la clase en donde se dicta una cátedra con base a definiciones y “resolución” de expresiones que distan mucho de ser realmente situaciones de aprendizajes en Matemáticas” (Arévalo, 2015, p.2).

Published: October 2024

Debido a necesidades de la industria como incrementar la producción y realizar tareas peligrosas para el hombre, se desarrollaron mecanismos automatizados que realizan operaciones de producción de manera más rápida, segura y económica. A estos mecanismos automatizados se les llamó robots. Los robots fueron diseñados y construidos desde hace varias décadas con el objetivo de prestar servicios a los humanos en tareas repetitivas; en la industria, los robots se emplean para elaborar trabajos de pintura, soldadura, ensamble de piezas, entre otros. En el área aeroespacial, han sido utilizados como rescatadores de satélites, en la recolección de muestras, en la exploración de terrenos y para labores de mantenimiento de las estaciones espaciales. Muchas aplicaciones que hace décadas se consideraban imposibles de realizar, hoy son realidad. Existe una gran variedad de familias de robots. Los más utilizados en la industria son los llamados manipuladores seriales y manipuladores paralelos. Los primeros, mucho más utilizados y estudiados que los segundos, especialmente en lo que respecta a su fabricación y su control [1]. Sin embargo, esta configuración en serie supone también una pérdida de dinamismo: cada accionamiento tiene que llevar el peso de los accionamientos que le siguen. Son configuraciones con grandes masas en movimiento, por lo que resulta complicado obtener velocidades altas de trabajo. En los últimos años se ha presentado un creciente interés de los investigadores en los manipuladores paralelos debido a sus ventajas sobre sus contrapartes seriales, esto se debe a que sin importar que los manipuladores paralelos tengan actuadores fijos en su estructura, o que se muevan muy próximos a ella, ninguno de los actuadores debe llevar el peso de otro cuando realiza un movimiento, todos ellos conectan la estructura fija con el cabezal de trabajo o la herramienta final. Por estas características las cadenas cinemáticas y los sistemas de accionamiento pueden ser más pequeños, lo que permite aumentar la masa útil que se puede mover con el manipulador [2]
Education as a female entrepreneurship catalyst
Authors: Vucetic Ivana , Kirin Snezana , Popovic-Pantic Sanja
Published: October 2024

The number of businesses in Serbia owned and managed by women is increasing,
but female entrepreneurs are still in the minority. This study aims to
explore characteristics, motivations, advantages, and disadvantages of
female entrepreneurship in Serbia in relation to differences in the
education level of female entrepreneurs. The main idea is that education
level influences the motivation to become an entrepreneur and the choice of
the business sector and that female entrepreneurs of different education
levels perceive the advantages and disadvantages of entrepreneurship
differently. The research was conducted during the first quarter of 2023.
The research sample included 104 female entrepreneurs from different sectors
and regions of the country. It was demonstrated that education level has an
impact on female entrepreneurship. The choice of business sector was
influenced by the education level of female entrepreneurs. The way female
entrepreneurs perceived the advantages and disadvantages of entrepreneurship
was, in some cases, associated with the level of education, while the
decision and motivation to become an entrepreneur were not. The results of
this study can be used for researchers and policymakers in the field of
entrepreneurship to increase the number of female entrepreneurs in Serbia.

Healthy eating is part and parcel to the effective management of diabetes, and registered dietitian nutritionists (RDN) need to play a major role. The American Diabetes Association Guide to Nutrition Therapy for Diabetes, edited by Alison Evert and Marion Franz, now in its third edition, is extremely evidence-based with large doses of experience and practicality. Although weight loss is important for the prevention of type 2 diabetes (T2D) in those at risk and in the management of T2D, and increasingly important in people with type 1 diabetes (T1D), initial steps should focus on the quality not quantity of the eating pattern. And recent data supports that there’s no need to worry about percentage of calories in the form of macronutrients; yet we all know the variable and time-dependent impact of type of carbohydrate on postingestion glycemic excursion and of type of fat (saturated/trans versus unsaturated) on low-density lipoprotein cholesterol (LDL-C).

Objective: Prenatal exposure to maternal diabetes is associated with increased risk of offspring heart defects. We evaluated associations with subtle infant cardiac changes.

Research Design and Methods: In a cohort of 25,486 infants with transthoracic echocardiography within 60 days of birth, we investigated associations between maternal pre-existing and gestational diabetes (GDM) and infant left ventricular (LV) structural and functional parameters, using linear regression to estimate adjusted mean differences (aMD) between groups.

Results: Infants exposed to maternal pre-existing diabetes (N=198) had thicker LV posterior walls (aMD 0.19 mm, 95% confidence interval [CI] 0.11, 0.27), smaller LV internal diameters in systole (aMD -0.27 mm, 95% CI -0.45, -0.18) and diastole (aMD -0.37 mm, 95% CI -0.59, -0.09), reduced stroke volumes (aMD -0.36 mL, 95% CI -0.61, -0.11), and increased heart rates (aMD 3.14 bpm, 95% CI 1.10, 6.18) and mitral valve early peak velocities (aMD 2.17 cm/s, 95% CI 0.31, 4.04) than unexposed infants (N=24,639). Infants born to mothers with GDM (N=649) had significantly smaller LV internal diameters in systole (aMD -0.13 mm, 95% CI -0.22, -0.03) and similar structural and functional changes as children exposed to pre-existing diabetes, albeit with smaller, non-significant aMDs. Higher third-trimester HbA1c levels were associated with smaller LV internal diameters and stroke volumes among infants exposed to pre-existing diabetes and with lower heart rates among infants exposed to GDM.

Conclusion: Maternal pre-existing diabetes and, to a lesser extent, GDM were associated with changes in infant LV structure and function.

Objective: To evaluate the clinical and laboratory outcomes of patients with type 2 diabetes by comparing the no reuse or reuse of syringes and needles for insulin application.

Research design and methods: Adults with type 2 diabetes who had reused syringes and needles at least three times were randomly instructed either to not reuse or to reuse insulin syringes and needles five times. The primary outcomes assessed were glycemic control, pain scores and skin complications (ecchymosis, lipohypertrophy, nodules, infection) at baseline and 4, 8 and 12 weeks after the intervention. Secondary outcomes included treatment adherence, quality of life, microbiological contamination of syringes and needles, needle quality and insulin injection technique.

Results: Among the 71 participants, who had a mean age of 59.7 ± 8.8 years, 59% were women with a median duration of diabetes of 18 years (10-25) and a body mass index of 31.7 kg/m2. The group that reused syringes and needles experienced an increase in the number of lipohypertrophy/nodules (+0.16 ± 0.08, p=0.040) but did not experience worsening pain or glycemic control, even when the syringes and needles were inserted into the skin with great effort. There was no difference in the total number of skin complications, quality of life or microbiological contamination. Both groups improved treatment adherence, with a greater increase in the reuse group.

Conclusions: The reuse of syringes and needles is associated with a modest increase in lipohypertrophy/nodules but does not have a short-term impact on glycemic control in patients with type 2 diabetes.
First step toward designing effective real-time control systems in laser directed energy deposition

Published: October 2024

In-process monitoring and control are essential for quality assurance and consistency of laser-based directed energy deposition processes. Detection of irregularities during deposition in terms of defects or flaws is based on in situ monitoring of output process parameters such as temperature, melt-pool geometry, or deposition height. The real-time feedback of these output parameters allows the development of control strategies for real-time adjustment of input process parameters, such as laser power or scanning speed, to correct detected deviations from the desired output process parameters. Therefore, criteria such as sensitivity, stability, correlation, trends, and interactions of the input-output process parameters have a direct impact on controller design, establishing, for example, control limits or tolerance ranges of the output parameters. This paper focuses on the study of the characteristics of output process parameters to input process parameters. This research involves analyzing and comparing the deposition of single tracks under various input process parameters, including laser power and scanning speed. Melt-pool geometry and temperature are estimated from a visual camera and a hyperspectral line camera, whereas the final deposition geometry is obtained from a laser triangulation scanner. The results show the linearity between input and output process parameters, the steadiness of the output process parameters, the relation between melt-pool and final deposition, and offer insights to design effective in-process control systems.
Geometry strategies for the repair of cylindrical gears teeth using laser-directed energy deposition
Authors: Montoya-Zapata Diego , Ortiz Igor , Alvarez Piera , Azpeleta Maria , Garcia Marta
Published: October 2024

Gears are essential components in power transmission systems. The replacement of the transmission of a wind turbine can reach more than $300 000 and face long lead times. Previous studies have shown that laser-directed energy deposition (L-DED) has the potential to be used in the repair of gears. However, there is a lack of understanding of the appropriate toolpath planning strategies and their impact on the performance of the gears repaired by L-DED. In this work, we study several strategies for the repair of cylindrical (straight and helical) gears. The strategies consider several types of gear tooth failures, allowing for the repair of a portion of the tooth and the reconstruction of the whole tooth. The studied strategies encompass planar and nonplanar slicing procedures. We manufactured several gear teeth to demonstrate the geometrical and kinematic feasibility of some strategies. We performed destructive analyses on the manufactured teeth to check for manufacturing faults. We used AISI 316L for these experiments, although we are assessing and testing powdered materials for their potential use in gear repair using L-DED. Future work will be devoted to the evaluation of the mechanical performance (e.g., wear resistance and bending fatigue) of the teeth manufactured with L-DED.
Improvement of layer fabrication efficiency and dilution rate for nickel based super alloy by multibeam directed-energy-deposition with blue diode lasers
Authors: Matsuda Ryuhei , Sato Yuji , Takenaka Keisuke , Kusaba Mitsuhiro , Tsukamoto Masahiro
Published: October 2024

A bead of nickel based super alloy was deposited on an SS304 substrate by a multibeam directed energy deposition method using a blue diode laser. Previously, the fabrication of nickel based super alloy using a blue diode laser had not been performed. Therefore, the laser output power and sweep speed were varied to investigate the effects of these variables on the bead. The results showed that laser output power and sweep speed affected the bead height, width, fabrication efficiency, and dilution rate in the fabrication of nickel based super alloy beads. In addition, we were able to produce a lower dilution than previously reported.
Å kome i gang med matematisk modellering i klasserommet – kan PISA-oppgåver vise veg frå kaos til system i første del av modelleringsprosessen?
Authors: Berget Ingeborg Lid , Løvgren Maria , Pettersen Andreas
Published: October 2024

Matematisk modellering handlar om å bruke matematikk til å løyse problem frå den verkelege verda. Resultat frå fleire studiar viser at den første delen av modelleringsprosessen, der problemet skal omsetjast til eit matematisk problem, er spesielt krevjande for elevar, og at matematikkoppgåver i liten grad utfordrar elevane i dette. I dette kapittelet presenterer vi eksempel på korleis matematisk modellering er framstilt i eit utval av litteratur om matematikkundervisning. Vidare gjer vi greie for utviklinga av eit analyseskjema som blir brukt for å undersøke kva for utfordringar elevane møter og ikkje møter i arbeid med modelleringsprosessen i PISA-oppgåver. Vi analyserer også to tidlegare gitte eksamensoppgåver for 10. trinn om matematisk modellering. I resultata kjem det fram at PISA-oppgåvene berre utfordrar elevane i delar av handlingane i å kjenne igjen og formulere i PISA-rammeverket, særleg å kjenne igjen struktur, mønster og samanhengar, og å lage ein matematisk modell. Gjennom kapittelet gir vi eksempel på ulike typar modelleringsoppgåver og presenterer både frigitte PISA-oppgåver og andre oppgåver. Vidare argumenterer vi for at analyseskjemaet kan vere nyttig for matematikklærarar for å bidra til økt refleksjon og bevisstgjering om kva for utfordringar knytte til matematisk modellering elevane møter i ulike oppgåver.
Long Term Paired Outcomes of Index and Redo per Oral Endoscopic Myotomy
Authors: Q Cai
Published: October 2024

Introduction: Per-Oral Endoscopic Myotomy (POEM) is a specialized procedure designed to improve symptoms by minimizing lower esophageal sphincter pressure in patients with achalasia. Despite excellent reported success rates, about 10% of patients have persistent or recurrent symptoms after procedure. There are limited studies looking at the efficacy of redo POEMS for these patients. In particular, there is no published data on comparing the paired effect of index POEM and redo POEM individually. We aimed to compare paired data of index and redo POEMs and provide election criteria for redo POEM. Methods: We conducted a retrospective observational study of all patients who underwent both index and redo POEM between August 2014 and January 2020 at Emory University. All patients underwent standard POEM protocol. We defined clinical success by an Eckardt score <3 post procedure. Results were analyzed with t tests, Chi squared tests where appropriate, or were otherwise reported as means with corresponding ranges. Results: 15 patients underwent redo POEM (ages 25-79, 53% female). One was lost to long-term follow up. There was no significant difference noted between index and redo POEM in procedure time (61.9 minutes vs. 62.2 minutes) (p=0.96), myotomy length (6.9 cm vs.6.1 cm) (p=0.13). 10 out of 15 patients (67%) achieved clinical success post-procedure with an Eckhardt score <3. Conclusion: Redo POEM procedure can be safely performed even on the same side of index POEM. Patients with previous interventions, those who clinically failed index POEM (never-responders), and those who initial responded (recurred) all can benefit from and should be offered redo POEM procedure. However, patients with severely diffusely dilated esophagus may not benefit from redo POEM and warrant surgical consultation for esophagectomy, if necessary.

Determining Absorbance in Different Inks Using VSC-8000 H/S Technique- A Non-Destructive Optical Microspectrophotometer Modality
Authors: P Kumar , P Sharma , D Bhandari
Published: October 2024

Examination of inks is an important aspect of questioned documents. In the present study, a non-destructive examination of inks was done owing to their different compositions namely, colorants, vehicles, solvents, dyes, resins, pigments, etc. This offers a chance for the questioned document examiner to individualize the ink when its authenticity and writer’s ownership, period of writing, or placement of ink on paper and individualization is under scrutiny. This is helpful in cases of threats, blackmail, kidnapping, suicide, ink-back dating, fake cheques and other cases. Conventionally, ink examination has been happening using TLC, HPLC, LC-MS, GC-MS, etc. In this paper, VSC-8000 has been used owing to its in-built micro-spectrophotometric modality, as it offers a non-destructive method to determine the absorbance and help individualize inks. For the present study Ball, Gel, Fiber tip pen, Sketch pen and Pencil of five different colors were used. Even bubbles on white paper were made and using VSC-8000 absorbance was noted for the visible length range. The results showed promising differentiation among the absorbance for different colors and pens. A lot more can be done by making a database library and exploring the absorbance under different VSC-based micro-spectrophotometric modalities. This method is clean, non-destructive, time-saving and userfriendly

Late-onset Vitamin K deficiency bleeding is a rare disease that develops as a manifestation of Vitamin K deficiency in children from 8 days to 6 months of age with an incidence of 4.4 to 72 cases per 100,000 newborns in countries where prophylaxis with Vitamin K1 preparations is not carried out and of 0 to 3 cases per 100,000 in countries where prophylaxis is carried out. In Russia the prophylaxis is carried out using menadione sodium bisulfite, a Vitamin K3 preparation, the effectiveness of which is questionable. One of the specific manifestations of the late-onset Vitamin K deficiency bleeding is intracranial hemorrhage (ICH), which occurs in more than half of all cases of the disease. This disease has not been described in patients with hemophilia A until now. Authors represent a clinical case report of the development of the late-onset Vitamin K deficiency bleeding by a massive ICH in a patient with hemophilia A.
Why Article 128 of the Criminal Code of the Russian Federation Is Not Applied
Authors: Sopin I.O.
Published: October 2024

Article 128 of the Criminal Code of Russia provides for liability for illegal hospitalization in a medical organization providing psychiatric care in inpatient conditions. The materials of judicial statistics show that it is practically not used. Purpose. The purpose is to establish the reasons for the non-application of this article. Methodology. The methodology includes the use of comparative-historical, comparative-legal, formal-logical and sociological methods. Results. Three hypotheses are put forward regarding the absence of real (preventive) judicial practice on the application of Article 128 of the Criminal Code of the Russian Federation: a) it is not applied because the critical situation in the field of psychiatric care is safe and practically excludes cases of illegal hospitalization in a medical organization providing psychiatric care in inpatient b) the dispositions and sanctions of the current norms of the article are formulated unsuccessfully, which creates obstacles to its enforcement; c) the activities of psychiatric institutions in the country are outside the zone of effective legal and social control, as a result of which the vast majority of cases of illegal hospitalization in a medical organization providing psychiatric care in inpatient conditions are latent. Conclusion. The first hypothesis is not confirmed by the results of the study, the second is partially confirmed, the third is fully confirmed. Thus, in order to increase the effectiveness of Article 128 of the Criminal Code of the Russian Federation, it is necessary to improve its dispositions and sledges, as well as to solve the problem of the creation by the state of a service independent of executive authorities in the field of health protection to protect the rights of patients in medical organizations providing psychiatric care in inpatient conditions.

Authors: Grishanin Nikita V. , Minevich Yakov V. , Merkushev Alexandra S.
Published: October 2024

Patriotism occurs in various forms at different historical moments. Our research is devoted to corporate patriotism and its manifestations. In the works published earlier, we came to the conclusion that any patriotism is based on the pentabasis of culture: family, society, country, state, person. All manifestations or strengthening of these positions in the company, one way or another, will influence the corporate employee and develop his attachment to the motherland, the ability to continue offspring, trust the state and work with the understanding that his success is the success of his family, society, country and state. In the course of the study, ten in-depth interviews were conducted with media representatives and about 100 media students were interviewed.

Most of the vehicles used by Malaysians have engines that only require petrol RON 95 to power the engine. However, many people claimed that utilising RON 100 instead of RON 95 for their vehicles will improve engine performance. Furthermore, many people speculate that using oil with a low octane level in an engine with low performance will affect the engine's performance. The goal of this research is to analyse and compare the engine performance and emissions on a spark ignition engine using gasoline RON 95 and RON 100. In this study, a single-cylinder four-stroke engine running with RON 95 and RON 100 has been tested on an engine dynamometer to evaluate the brake power, torque, specific fuel consumption, and exhaust emissions. The emissions from the engines have been determined using a gas emissions analyser. The outcomes of the experiment have been analysed based on engine torque, braking power, and exhaust emissions. Based on the analysis, torque, brake power, and emissions data obtained from the dynamometer engine, RON 100 has a higher and smoother performance than RON 95.
