Authors: Cerros Rodríguez Elisa
Published: May 2024

La pandemia por COVID-19 ha ocasionado graves afectaciones en diferentes ámbitos a nivel mundial, donde el educativo no ha sido la excepción. El objetivo del presente artículo es analizar las tensiones que hemos enfrentado tanto estudiantes como profesores durante este prolongado tiempo de confinamiento, el cual provocó trasladar las actividades educativas a entornos virtuales, teniendo una serie de consecuencias en los procesos formativos. Analizamos de manera puntual la situación que vivieron estudiantes de la licenciatura en trabajo social de la Universidad de Guadalajara, a partir de la investigación cuantitativa realizada por integrantes de la Red de Investigación Académica sobre Trabajo Social: Formación y Ejercicio Profesional (RIATS) en dos cohortes 2020 y 2021.Entre los resultados destacamos que los estudiantes presentaron deterioro en su salud física. Los principales padecimientos fueron dolor de cabeza y alergias. Además, señalaron un deterioro de su salud mental, manifestada particularmente a través de ansiedad e insomnio. Respecto al ámbito académico, los resultados evidencian tensiones y conflictos en su proceso formativo debido, entre otros factores, al prolongado confinamiento; al cambio de sus clases e interacciones a entornos virtuales; el no contar con las condiciones necesarias (en materia de equipo, acceso y calidad de conexión a internet, y un lugar adecuado para tomar sus clases), así como a la tenue relación docente – alumno, reflejada en una escasa o nula interacción y retroalimentación académica. Todo ello tuvo repercusiones en su aprendizaje y en sus expectativas formativas.

Published: May 2024

Abstract: Blockchain, smart contracts, and the Internet of Things (IoT) are essential technologies for the business process reengineering of supply chains in the era of Industry 4.0. The agricultural food supply chain is one of the research areas where these disruptive technologies can play a crucial role in automating business processes, providing real-time goods monitoring, and securing transactions. With the help of blockchain, smart contracts, and the IoT, a product’s health and environment can be monitored throughout the supply chain. In this study, we have critically examined the relevance of these technologies through various activities of the agriculture supply chain using the approach of Business Process Modeling (BPM). Agriculture is a big part of the economy of any country because it helps feed the entire population. It connects and communicates with all of the related industries. If the agriculture base is strong, it is generally regarded as a socially and politically stable society. Many modern farms make use of cutting-edge technology and sciatic and technological ideas. The maximization of the profits relies on some farmers’ vegetables and fruits with chemicals. Chemical fertilizers, insecticides, and other compounds are used in several plants and fruits.

Tensor network decompositions for absolutely maximally entangled states
Authors: Pozsgay Balázs , Wanless Ian M.
Published: May 2024

Absolutely maximally entangled (AME) states of k qudits (also known as perfect tensors) are quantum states that have maximal entanglement for all possible bipartitions of the sites/parties. We consider the problem of whether such states can be decomposed into a tensor network with a small number of tensors, such that all physical and all auxiliary spaces have the same dimension D. We find that certain AME states with k=6 can be decomposed into a network with only three 4-leg tensors; we provide concrete solutions for local dimension D=5 and higher. Our result implies that certain AME states with six parties can be created with only three two-site unitaries from a product state of three Bell pairs, or equivalently, with six two-site unitaries acting on a product state on six qudits. We also consider the problem for k=8, where we find similar tensor network decompositions with six 4-leg tensors.

Authors: Viphindrartin Sebastiana , Lestari Widarni Eny , Niken Wilantari Regina , Apriono Markus , Bawono Suryaning
Published: May 2024

This research employs a panel vector model to analyze panel data, examining the relationship between public debt, economic growth, interest rates, consumption, and net exports in Southeast Asia from 1990 to 2020. This quantitative study focuses on vector analysis using secondary data from the World Bank for the specified period. The findings reveal that public or state debt significantly inhibits most economic variables, suggesting a detrimental impact on Southeast Asia. A notable observation is the effect of rising interest rates on net exports, highlighting how increased rates hinder the exports of ASEAN member countries. Contrary to expectations, the analysis indicates that government spending escalates public debt. Furthermore, Southeast Asian consumption appears to bolster exports through international trade agreements. Interestingly, exports are found to increase government spending, implying a contribution to state revenues. A key finding is that economic growth, marked by GDP increases, positively influences all variables in this study, signifying that GDP growth spurs both the monetary and real sectors of the Southeast Asian economy.

Published: May 2024

Financial inclusion has garnered attention from policymakers globally due to its potential to spur economic growth, alleviate poverty, and decrease unemployment. This study focuses on estimating the financial inclusion index across ten Southeast Asian countries utilizing principal component analysis. The objective is to identify the most representative index capable of accurately reflecting the financial inclusion indicators specific to each country. Additionally, the research seeks to explore the impact of financial inclusion on the unemployment rate. Data spanning from 2011 to 2021 were sourced from the World Bank. By employing panel regression estimation, the study reveals that digital financial inclusion does not significantly influence the unemployment rate, as indicated by a significance value of 0.118. Furthermore, a similar lack of impact was observed concerning GDP. Conversely, the inflation rate and education level variables affected the unemployment rate significantly, with significance values of 0.028 and 0.021, respectively. These empirical results suggest that policymakers should implement strategies to enhance financial inclusion, such as reducing the costs associated with financial services, offering incentives to the informal sector, and promoting education on the significance of financial instruments and institutions.
Can fiscal transfers effectively reduce poverty in the Gorontalo Province?
Authors: Arham Muhammad Amir , Humalanggi Mahyudin , Tantawi Rezkiawan , Kusuma Citra Aditya
Published: May 2024

The central government has increasingly diversified and expanded fiscal transfers to local authorities to enhance community welfare rapidly. However, in Gorontalo, although poverty rates have declined, the pace of reduction has slowed despite an increase in the value of transfers. This study aims to identify the fiscal transfer mechanisms most effective in reducing Gorontalo's poverty rate. It focuses on several types of fiscal transfers, including the Special Allocation Fund (DAK), Village Fund Allocation (ADD), Family Hope Program (Program Keluarga Harapan, PKH), Smart Indonesia Program (Program Indonesis Pintar, PIP), and Social Assistance. Utilizing panel data regression analysis covering all six districts/cities in Gorontalo Province over the last five years (2018-2022) and employing the Fixed Effects Model (FEM), the findings suggest that PIP assistance has the most significant impact on poverty reduction, although its effects are more long-term. Moreover, the study finds that while ADD transfers notably enhance community welfare, the two-decade-long DAK transfers have inadvertently worsened poverty levels in Gorontalo. This issue stems from the DAK's allocation formula, which does not directly target the income improvement of low-income populations. Both PKH and Social Assistance have shown little positive effect on poverty alleviation in the region. Consequently, the study recommends that the government prioritize expanding and funding enhancement of PIP assistance, considering many underprivileged individuals remain unreached by this support. Additionally, it suggests increasing the ADD to accelerate development in poverty-stricken rural areas.

Authors: (Corresponding Author) Aiswarya S (Corresponding Author) , R Gomathi
Published: May 2024

Multimedia means text, image, audio or video file and transferring multimedia files through the internet are noticeable one. Multimedia securing techniques are additionally used to protect the file. Securing multimedia image file is difficult by using formal encryption techniques such as AES, RSA because of high correlation between pixels. For encryption, chaotic map with XOR function is used and to provide double protection, steganography technique is used. After the encryption, encrypted image is hidden into the cover image file using LSB-steganography technique. For that, from the cover image, the rectangular positioned pixel values are selected and the encrypted image values are hidden into the selected rectangular positioned pixel locations of the cover file. Embedded image i.e., stego image is transmitted to the recipient through the internet and the reversal process is carried over at the retriever side. The performance of this proposed algorithm is analyzed by using many numerical measures such as NPCR, UACI and PSNR. These values are calculated and compared with existing methods. The obtained average NPCR, UACI and PSNR values are 99.8004%, 37.6773% and 46.41 respectively. From these statistical values, compared to existing methods, the projected work provides better result. Correlation analysis is also performed and the values are compared between the secret image and the chaotic map encrypted image. From the comparison, it is clear that the chaotic map based image encryption and steganography method provides more security and robustness in the wireless secret image transmission.

Background: Survival of children with cancer has markedly improved over recent decades, largely due to intensified treatment regimes. The intensive treatment may, however, result in fatal complications. In this retrospective cohort study, we assessed temporal variation in the incidence of treatment-related death and associated risk factors among children diagnosed with cancer in Denmark during 2001–2021.
Method: Among all children diagnosed with first incident cancer before age 15 years recorded in the Danish Childhood Cancer Register (n = 3,255), we estimated cumulative incidence of treatment-related death (death in the absence of progressive cancer) within 5 years from diagnosis using Aalen–Johansen estimators and assessed associated risk factors using Cox regression.
Results: Among all 3,255 children with cancer, 93 (20% of all 459 deaths) died from treatment. Of these treatment-related deaths, 39 (42%) occurred within 3 months of diagnosis. The 5-year cumulative incidences of treatment-related death were 3.3% during 2001–2010 and 2.5% during 2011–2021 (p = 0.20). During 2011–2021, treatment-related deaths accounted for more than half of all deaths among children with haematological cancers. Risk factors varied according to cancer group and included female sex, age below 1 year at diagnosis, disease relapse, stem cell transplantation, central nervous system involvement, and metastasis at diagnosis.
Interpretation: Despite increasing treatment intensities, the incidence of treatment-related death has remained stable during the past 20 years in Denmark. Still, clinical attention is warranted to prevent treatment-related deaths, particularly among children with haematological cancers. Patient characteristics associated with increased treatment-related death risk support patient-specific treatment approaches to avoid these fatalities.

Published: May 2024

Background and purpose: Length of hospital stay after hip and knee arthroplasty is about 1 day in Denmark with few patients discharged on the day of surgery. Hence, a protocol for multicenter implementation of discharge on day of surgery has been instituted. We aimed to describe the implementation of outpatient hip and knee arthroplasty in a multicenter public healthcare setting.Methods: We performed a prospective multicenter study from 7 public hospitals across Denmark. Patients were screened using well-defined in- and exclusion criteria and were discharged on day of surgery when fulfilling functional discharge criteria. The study period was from September 2022 to February 2023 with variable start of implementation. Data from the same centers in a 6-month period before the COVID pandemic from July 2019 to December 2019 was used for baseline control.Results: Of 2,756 primary hip and knee arthroplasties, 37% (95% confidence interval [CI] 35–39) were eligible (range 21–50% in centers) and 52% (range 24–62%) of these were discharged on day of surgery. 21% (CI 20–23) of all patients (eligible and non-eligible) were discharged on day of surgery with a range of 10–31% within centers. This was an additional 15% (CI 13–17, P < 0.001) compared with patients discharged in the control period (6% in 2019).Conclusion: We found it possible to perform outpatient hip and knee replacement in 21% of patients in a public healthcare setting, probably to be increased with further center experience.

Published: May 2024

Agentes económicos como los trabajadores son estudiados desde la racionalidad del Homo economicus, aunque su comportamiento debe entenderse desde la perspectiva moral-emocional del Homo moralis motus. Por tanto, el objetivo del presente trabajo fue establecer el nivel de competencia moral y emocional a partir de dos conceptos básicos, pero opuestos: la culpa y el orgullo. Para ello, se aplicó el cuestionario moral emocional a 212 trabajadores de una organización. Mediante el análisis estadístico descriptivo y de varianza, se encontró el nivel más alto de competencia moral en los trabajadores de base, mientras que el nivel más bajo se registró en los trabajadores eventuales. Esta investigación demuestra que, mediante el análisis de la competencia moral, se puede identificar el equilibrio moral emocional del trabajador. Por ende, se puede concluir que la evaluación del Homo moralis motus permitiría, potencialmente, observar y anticipar el correcto comportamiento del trabajador en una organización.

Published: May 2024

Workload can be defined as the difference between a worker's ability and job demands. Based on observations that have been made, it is known that madukismo sugar companies get an increasing demand value in each season of production, so this causes an increase in the number of working hours that apply to the company, which has the potential to increase their mental work. This study investigated the mechanical mental workload of workers at Madukismo Sugar Company using the NASA-TLX method, a multidimensional assessment tool. The NASA-TLX method is a multidimensional assessment method that can measure the overall mental workload to determine the mental workload felt by each worker.

This research aims to analyse the quality of childcare services by considering local wisdom and traditional games and conducting a case study at OMAH BOCAH. The SERVQUAL method measures parents' perceptions of the quality of services provided. In contrast, the QFD method is used to design childcare programs that align with parents' needs and expectations, taking into account local wisdom and environmental values. Uniqueness of traditional games. This research uses a qualitative approach with data collection techniques through observation, interview, and documentation studies. The collected data was then analysed using qualitative analysis methods to identify key factors of service quality implemented at OMAH BOCAH. Furthermore, the QFD method designs a higher quality and sustainable childcare program by integrating local wisdom and traditional games. The results of this research will provide a deeper understanding of how local wisdom and traditional games can improve the quality of childcare services. Thus, this research can provide useful recommendations for other childcare service providers to integrate aspects of local wisdom and the uniqueness of traditional games to improve the quality of their services. Keywords: local wisdom, traditional games, Servqual method, QFD

They were irregular in ten cases, rectangular in nine cases, and triangular in three cases. It has been established that the size and shape of the auditory tube in prematurely born children do not have deﬁ nitive dimensions and its location diﬀ ers from that in newborns. The pharyngeal openings of the auditory tubes are at the level of the hard palate and, in newborns, above the level of the hard palate. The tympanic openings from the lower part of the anterior wall of the tympanic cavity in fetuses of the seventh month of intrauterine development move completely to the upper part of it and open into the supratympanic space in fetuses of the tenth month. The identiﬁ ed features are important in improving the technology and adequacy of surgical treatment and manipulations in prematurely born children.The structure and syntony of the auditory tube were studied in 35 human fetuses of the seventh to tenth months of intrauterine development and 11 corpses of newborns. In the fetuses of the seventh month, the shape of the tympanic openings of the auditory tubes was irregular in eight cases, triangular in three cases, and rectangular in eleven cases. The drum holes shift to the top even more. They had an irregular shape in nine cases and a rectangular shape in ﬁ ve. In the tenth month, the tympanic openings of the auditory tubes move to the upper part of the anterior wall of the tympanic cavity and open into the supratympanic space. They had an irregular shape in ten cases, and in six cases we observed a rectangular shape of them. The tympanic openings of the auditory tubes in newborns are located in the upper part of the anterior wall of the tympanic cavity and open into the supratympanic space. They were irregular in ten cases, rectangular in nine cases, and triangular in three cases.

The study of the age-related morphology of the surface structures of the face at the stages of the postnatal period of human ontogenesis under normal conditions allows both morphologists and clinicians to signiﬁ cantly understand several pathological changes, reveal the causality of destructive processes, and propose anatomically based methods of pain relief and surgical interventions. Recently, in connection with the development of maxillofacial surgery, the details of the macromicroscopic preparation of the surface vessels and nerves of the human face are of great interest, which is of important practical importance for establishing the forms of individual anatomical variability.The purpose of the study was to determine the most rational sequence of actions during the preparation of surface vessels and nerves of the face.The study of the fetal anatomy of the superﬁ cial vessels and nerves of the face was carried out on 18 preparations of human fetuses of 4-10 months using macromicroscopic preparation, injection of vessels, and morphometry without external signs of anatomical deviations or congenital malformations of the structures of the head.The proposed and tested method of dissection of superﬁ cial vascular- nervous structures of the face in human fetuses ensures the standardization of obtaining data on the typical, individual, and age-related anatomical variability of the branches of the facial and trigeminal nerves and their nerve connections, some branches of the external carotid artery, namely: facial and superﬁ cial temporal arteries, inﬂ ow of facial, superﬁ cial temporal and submandibular veins, as well as intra- and intersystem arterial and venous anastomoses. Variants of blood supply and innervation of facial muscles in human fetuses of diﬀ erent ages have been established.The sequence of actions used during the preparation of superﬁ cial arterial and venous vessels and nerves of the face will help maxillofacial and plastic surgeons to individually choose the most rational method of surgical intervention for the restoration of defects of the head area, as well as the method of analgesia.

A inclusão das pessoas com deficiência nas práticas esportivas pode resultar na melhora da aptidão física e motora, a vivência de novas experiências e redução do distanciamento social. Assim, o presente trabalho objetivou identificar as percepções das Pessoas com Deficiência (PcD) e de profissionais de Educação Física referente ao processo de inclusão por meio da natação. No que se refere a metodologia, trata-se de uma pesquisa de abordagem qualitativa, com a utilização das técnicas de revisão bibliográfica e pesquisa de campo, com entrevista semiestruturada e para apreciação dos dados e resultados a análise de conteúdo. Essa pesquisa apresentou como resultados positivos a natação como uma das possibilidades esportivas capaz de promover a inclusão, sendo importante e gratificante para o reconhecimento que começam a ter, tanto pessoal como profissionalmente. Conclui-se que, a prática e a vivência da natação sugerem benefícios físicos, psicológicos e sociais, aumentando sua capacidade funcional, reabilitação, inclusão, socialização e saúde do praticante.

O poço de luz é uma solução arquitetônica utilizada quando não há possibilidade de iluminar, naturalmente, um ambiente pelas faces externas da edificação. Diferentes cidades brasileiras permitem seu uso a partir de uma fórmula para o cálculo de sua geometria. Este trabalho tem como objetivo identificar se as dimensões mínimas, determinadas pela legislação urbana de Juiz de Fora (Minas Gerais) para o poço de luz, são suficientes para garantir a adequada iluminação natural nos ambientes por ele servido. Para isso, foram realizadas simulações computacionais de poços de luz de edificações de 2, 4, 6 e 8 pavimentos, por meio dos programas Grasshopper e ClimateStudio, plug-ins do software Rhinoceros. A métrica de avaliação da iluminação utilizada foi o Daylight Autonomy, que considera a média da porcentagem das horas de ocupação, ao longo do ano, em que os sensores registraram iluminância igual ou maior a 150 lux. Os resultados indicaram que as áreas mínimas atuais indicadas para o poço de luz na legislação não permitem que os ambientes tenham níveis adequados de iluminância. Percebeu-se, ainda, que os pavimentos superiores são beneficiados com o aumento do diâmetro do poço, porém, a ampliação do diâmetro não é suficiente para compensar a perda de luz, devido ao aumentoda profundidade do poço. Resultados em diferentes horários nos solstícios e a distribuição da iluminação nos ambientes são discutidas. O trabalho indica, de forma clara, a necessidade de um reestudo da legislação urbana da cidade.
