Published: March 2024

Objetivo: Proponer un modelo de analítica de datos para contribuir al seguimiento del flujo de caja que apoye el sostenimiento de las mipymes. Diseño/metodología: Se llevó a cabo una caracterización de los procesos de flujo de caja en las mipymes colombianas mediante la construcción de un estado del arte y del análisis descriptivo de datos obtenidos a partir de una encuesta. Resultados: Se ha determinado que la adopción del control de flujo de caja en las mipymes colombianas no es tan frecuente como sería recomendable, considerando su baja tasa de supervivencia. Adicionalmente, se observó que la implementación de este control raramente se realiza utilizando software especializado. En cuanto a los modelos de análisis predictivo examinados, el modelo de bosques aleatorios demostró ser el más eficaz, con una precisión del 76.67, una sensibilidad del 83.33 y una especificidad del 70. En relación con los modelos de análisis descriptivo y diagnóstico, se han desarrollado propuestas de análisis que se adaptan a la naturaleza y disponibilidad de la información a reunir de las mipymes colombianas. Conclusiones: El uso de herramientas informáticas del tipo de analítica de datos puede contribuir a la mitigación de riesgos de iliquidez y de insolvencia de las empresas, ya que les ofrece a los emprendedores una visualización de información del flujo de caja en diversos escenarios, una proyección de posibles periodos de déficit o superávit y un apoyo para una mejor toma de decisiones de operación, inversión y financiación. Originalidad: En estados del arte, realizados entre 2012 y 2022, no se encontraron resultados significativos relacionados específicamente al área de analítica predictiva aplicada al flujo de caja, y ninguno similar al modelo de analítica sobre flujo de caja propuesto en este manuscrito, el cual busca reducir la cantidad de mipymes que quiebran Colombia debido al desconocimiento de su información financiera y la falta de apoyo en la toma de decisiones.

Published: March 2024

Introduction. The increased intensity of noise and vibration of railway traffic may become not only an urgent problem in the field of occupational safety, but also a serious environmental problem in the near future due to the constant need to increase the weight of freight trains, the speed of passenger trains and the capacity of railway lines. Recently, a lot has been done to minimize the negative effects of noise and vibration in railway transport. However, the problem of exceeding the indicators of vibration noise factors remains relevant. Reducing the harmful effects helps to improve the working conditions of train crew employees and improve the comfortable conditions of transport passengers. As a rule, the main focus of the analysis is on the external impact of vibroacoustic factors on residential areas and less attention is paid to the impact on rolling stock. However, these studies do not provide a complete picture of how noise and vibration actually affect the train in motion. The aim of the study was to obtain the result of an analysis of the impact of vibroacoustic factors on train crew workers and to propose a method of comprehensive protection based on the use of vibration damping materials.Materials and Methods. In the course of the work, regulatory documents were studied, a comprehensive analysis of relevant information on this topic was carried out, and methods for calculating vibration and vibration acceleration were used. The values of the sound pressure levels were obtained using a SPM-101 sound level meter. The object of the study was a carriage of the "reserved seat" type in the process of movement. As part of the research plan, sound pressure was measured at selected sites and a class of working conditions was determined.Results. The result of the analysis of the impact of vibroacoustic factors on train crew workers indicated the need to strengthen comprehensive measures to protect them. The obtained calculation of the vibration force became the basis of the method proposed by the authors to minimize the harmful effects of vibroacoustic factors, which was based on the use of vibration and sound insulation materials suitable for the necessary acoustic parameters in the construction of the car. In particular, it was proposed to cover the floor of the car with dense rubber and the ceiling of the car with an inorganic fiber material for sound insulation. The work also provides an economic assessment of the effectiveness of measures to minimize harmful vibration noise effects.Discussion and Conclusion. The proposed methods for minimizing noise and vibration impacts can help reduce the level of sound pressure and vibration indicators to standard values, which will significantly reduce the negative impact of vibroacoustic factors on train crew workers and railway passengers. The considered complex for minimizing vibration and noise includes a set of methods in which affordable materials based on recycled substances have found application.
Content and Dispersion of Ferroalloys in the Coating During Microarc Alloying of Steel

Published: March 2024

Introduction. The main disadvantage of traditional processes of diffusion surface hardening of steel products is its long duration. Therefore, the problem of intensification of such processes is relevant. To solve it, the use of high-energy effects on the material is proposed, which allows us to obtain a hardened surface layer from a coating composed of ferroalloy powders containing alloying elements. There is no data in the literature on the required content and dispersion of such powders in the composition of the coating. The aim of this study was to select the particle size of ferroalloys and their concentration in the coating to achieve the most effective hardening of the processed product.Materials and Methods. For experimental studies, cylindrical samples made of steel 20 with a diameter of 12 mm and a length of 35 mm were used. On the surface of these samples, an alloying coating containing ferroalloy powders and an electrically conductive gel as a binder was applied. After that, the samples were immersed vertically for half their length into a metal container, which was then filled with carbon powder with a particle size of 0.4–0.6 mm. Then an electric current of 2.5 to 3.0 A was passed in the circuit power source — container — carbon powder — sample. The duration of the process was 2–8 minutes.Results. The calculated estimation of the electrical conductivity of coal powder was performed, and the thermophysical parameters of microarc heating of steel were calculated. These include the power released by electric current on the surface of the steel product, the density of the heat flux, and the energy of a single microarc discharge. The expressions for calculating the particle size of ferroalloy powder were obtained, as well as the experimental dependencies of the diffusion layer thickness on the particle size of ferroalloys and their content in the coating.Discussion and Conclusion. The results of this study have allowed us to determine the size range of ferroalloys and their content in the coating. This information is essential for optimizing the alloying process and ensuring the most efficient surface hardening treatment for steel products. The data collected will be used to develop improved technological processes for the surface hardening process, leading to improved product quality and performance.

Abstract

OBJECTIVE
To assess the characteristics of blebs formed after Ahmed glaucoma valve (AGV) surgery in dogs using ultrasound biomicroscopy (UBM) and to analyze their correlation with postoperative intraocular pressure (IOP).

ANIMALS
16 eyes (13 dogs) were diagnosed with primary angle-closure glaucoma and were followed up after AGV surgery from June 2021 to September 2023.

METHODS
In this prospective study, UBM examinations were performed to assess bleb characteristics, including bleb wall thickness and reflectivity. IOP at the time of UBM imaging and the duration from AGV surgery to UBM imaging were recorded. Histological examination of an enucleated eye removed due to uncontrolled IOP leading to blindness was also conducted.

RESULTS
A significant correlation was observed between IOP and relative reflectivity (Pearson r = 0.60; P = .01), and a negative correlation was observed between bleb wall thickness and relative reflectivity (Pearson r = −0.72; P = .002). No significant correlation was observed between the duration from AGV surgery to UBM imaging and either bleb wall thickness or relative reflectivity, respectively. Histological examination of the enucleated eye revealed collagen-rich fibrous encapsulation of the bleb wall, including myofibroblasts that exhibited positive α-smooth muscle actin immunostaining.

CLINICAL RELEVANCE
In dogs that underwent AGV surgery, less dense, thick-walled blebs on UBM tended to maintain IOP within the normal range. However, denser, thinner-walled blebs showed IOP levels above the normal range despite the use of antiglaucoma medications. UBM is a useful tool for evaluating bleb characteristics and their influence on IOP regulation after AGV surgery in dogs.

Abstract
The present study aimed to determinate the effect of external progesterone (P4) supplementation on luteolysis in cows under heat stress. Forty-eight (n=48) dairy cows in the period from July–September 2018 were part of and at day 35±3 postpartum scored for BSC, synchronized using PG-3-G + Ovsynch protocol and randomly allocated into two treatments: PRID group (n=27) treated with external P4 device between G1 and PGF2α and CON group (n=21) left without treatment. Collection of blood samples to assess P4 concentrations was done at Pre-PG, at G1, at PGF2α, at 72 h after PGF2α (at timed artificial insemination TAI) and at d 21 after TAI. The pregnancy diagnosis was done at d 21 and d 30 after TAI by ultrasound. The average temperature-humidity index (THI) was 79.5±0.6. At G1, the P4 was significantly lower in the PRID group (1.84±0.99 ng/mL) in comparison to the CON group (2.97±1.82 ng/mL). In contrast, at PGF2α, there was a tendency (p=0.09) of increased P4 concentration in PRID group compared with the CON group (4.26±1.68 and 3.74±2.39 ng/mL), respectively. At TAI, more PRID cows (p=0.0001) had a lower P4 (0.06±0.03 ng/mL), in comparison to CON (1.28±2.41 ng/mL). At d 21 and d 30 after TAI, more PRID cows were predicted and diagnosed pregnant (16/27 or 59.25% and 13/27 or 48.14%) compared with the CON group (11/21 or 52.38% and 8/21 or 38.08%) respectively, but without any significant differences. Supplementation of the P4 during the Ovsynch protocol increases the P4 before TAI and reduces the incomplete luteolysis in heat stressed dairy cows.

Abstract
Hyperadrenocorticism (HAC) in dogs is routinely treated with trilostane single-dose (CTG) which is reported to cause adverse reactions. The current retrospective study of several dogs with terminal stage of HAC aimed to compare the clinical, hematological, and biochemical effects of trilostane titration-dose treatment (TTG) with the single-dose treatment (CTG). All clinical cases (n=7) were confirmed on HAC by anamnestic, clinical, hematology, biochemistry, and low-dose dexamethasone suppression test findings, indicative for Cushing’s disease. Two cases were treated with CTG (2.2-6.7 mg/kg, single dose daily) and their treatment was discontinued on the second week due to adverse reactions. The TTG cases were treated for up to 12 weeks (0.5 mg/kg once daily for 7 days, and then with 0.5 mg/kg twice daily for 7 days). Blood samples and clinical checks were performed on 0., 4., and 12. weeks of the treatment. Hemoglobin was non-significantly higher in TTG at 12 weeks. Alanine transaminase was significantly lower in the TTG cases on the 12. week of the treatment (78.04±15.37 U/L) compared to the 0-week (137.81±24.03 U/L), and 4-week samples (131.92±23.36 U/L). No significant differences were observed with the CTG cases. Alkaline phosphatase was significantly lower on 12-week samples in TTG (251.02±93.06) compared to the 4-week (567.94±283.93 U/L), and 0-week samples (1,341.84 U/L). In conclusion, TTG has indicated to have significantly higher tendency to decrease alanine transaminase and alkaline phosphatase, alleviating the negative effects on the liver. The clinical findings were more adverse for the CTG.

Published: March 2024

Objective: The research aims to determine the leadership style found in villages in the Lake Toba area which have natural, biological and cultural potential, where presumably, the head of the village head will be able to make breakthroughs in developing the village into a tourist village. The tourism development target for Lake Toba is 1,000,000 foreign tourist visits in 2019, and the damage to tourism infrastructure due to the 2020-2022 pandemic out-break makes this target even more difficult to achieve.

Theoretical framework: Qualitative research conducted using the phenomenological approach. Research validity was obtained through triangulation of data sources and reliability was carried out through repeated observations a year later.

Method: Of the 30 villages located on the shores of the lake, 15 villages were selected for observation and interviews, afterward reduced to 10 villages using feature and demographic approaches. This research is increasingly necessary considering that the world tourism trend is towards the environment, and the development of villages into tourist area can be achieved if the village head's leadership style is appropriate.

Result and conclusion: The research proves the similarity of village heads' experiences in leading villages, integratedly, in a bureaucratic, democratic and transformative manner, where these actions can create change and increase the welfare of village residents. The village head who supports the development of National Tourism Strategy Area of Lake Toba leads holistically.

Research implications: The research provides the government with a standard leadership model that the village head can use to oversee the hamlet's transition into a tourism destination and obtain accreditation.

Originality/value: The research found a leadership model, namely leadership based on statutory regulations, local wisdom and transformation, which was classified then as bureaucratic, democratic and transformative leadership models.
Unraveling the Nexus: A Bibliometric Analysis of Subjective Wellbeing, Individualism-Collectivism and Sustainable Consumption Research in The Last Decade
Authors: Zimmermann Cristiane Soethe , De Quadros Cynhtia Boos , De Souza Júlio Cesar Lopes 
Published: March 2024

Purpose: This paper intends to contribute to the academic field by pointing out trends in studies on subjective wellbeing and exploring the possibility of new interconnections with different constructs, especially in a scenario of significant changes in consumption behavior, such as the post-pandemic one. In the managerial area, it aims to collaborate by providing relevant information on the effects of sustainable consumption on subjective wellbeing, particularly for marketing professionals and the development of marketing strategies.

Method: The study conducts descriptive and bibliometric analyses of the 236 selected articles found in the literature over the last ten years, establishing connections between the main theories.

Results and conclusion: Although the studies found do not directly associate the three main constructs that are the focus of the research, there is a clear relationship between them. Studies show individualistic or collectivistic orientation as an antecedent of sustainable consumption; the influence of culture on the level of subjective wellbeing; as well as a positive relationship between sustainable consumption habits and subjective wellbeing and an inversely proportional relationship between individualism and sustainable consumption.

Research implications: We can understand as relevant that future studies on sustainable consumption should take into account individualism-collectivism and wellbeing, seeking a comprehensive and systematic approach to sustainable consumption, considering the role of individual citizens in society, and exploring the link between the provision of sustainable products and diverse sustainable consumption practices. It is necessary to consider the complex and multifaceted nature of wellbeing, as well as the cultural and societal factors that influence it, and take a holistic approach that considers the interplay between individual, community, and social wellbeing.

Originality/value: The study contributes to the integration of constructs, since the article seeks to fill a gap by exploring the interconnection between three main constructs - subjective wellbeing, individualism/collectivism and sustainable consumption. In doing so, it provides an integrated view that can enrich theoretical discussions in these areas. In addition, the bibliometric analysis reveals recent trends in the literature, highlighting the areas that have received the most attention and those that are less explored. This information can guide researchers for future studies and explore knowledge gaps. By considering the influence of culture on the relationships between the constructs, the article also contributes to a deeper understanding of how cultural differences can shape perceptions of wellbeing and sustainable consumption practices.
