Authors: Rocha Roseli  Gonçalves da , Faria Filho Fausto de Melo
Published: February 2024

A implementação de iniciativas artísticas e culturais nas instituições de ensino proporciona aos estudantes uma experiência que vai além dos limites acadêmicos. Isso contribui significativamente para a formação de cidadãos mais críticos e reflexivos, promovendo uma educação completa e totalmente integrada ao mundo ao redor deles. Pensando nessas possibilidades, este artigo visa a analisar os desafios enfrentados pelo Instituto Federal Goiano - IF Goiano para a consolidação da cultura e discutir possibilidades para gerir, promover e garantir o direito de acesso à cultura pelos estudantes, servidores e comunidades locais. No decorrer do texto, apresentamos pontos importantes dos documentos institucionais e as experiências que tangem a implementação de ações de arte e cultura desenvolvidas ao longo dos últimos oito anos. As narrativas dos estudantes destacam a inegável importância do conhecimento em arte e cultura, e benefícios decorrentes do envolvimento nessas atividades. No entanto, observa-se a necessidade de os gestores implementarem efetivamente as diretrizes previstas nos regulamentos institucionais e estabelecerem colaborações com atores externos. Nesse cenário, a presença e o fomento da arte e da cultura emergem como elementos essenciais na construção da formação humana e cidadã.

Soft computing implementations for evaluating Los Angeles abrasion value of rock aggregates from Kütahya, Turkey
Authors: Köken Ekin
Published: February 2024

The Los Angeles abrasion value (LAAV) of rocks is a critical mechanical aggregate property for designing road infrastructures and concrete quality. However, the determination of this critical aggregate property is labour-intensive and time-consuming and thus, in the literature, there are many predictive models to estimate the LAAV for different rock types. However, most of them are based on classical regression analyses, limiting their broader usage. In this study, several soft computing analyses are performed to develop robust predictive models for the evaluation of LAAV of rocks in the Ilıca region (Kütahya – Turkey). The main motivation for implementing soft computing analyses is that precise predictive models might be useful when exploring suitable rock types that are manufactured in crushing–screening plants. For this purpose, a comprehensive laboratory schedule was established to obtain some inputs for the evaluation of LAAV. As a result of the soft computing analyses, four robust predictive models are developed based on artificial neural networks (ANN), multiple adaptive regression spline (MARS), adaptive neuro-fuzzy inference system (ANFIS) and gene expression programming (GEP) methodologies. The performance of the proposed models is investigated by some statistical indicators such as R2 and RMSE values and scatter plots. As a result, the ANFIS-based predictive model turns out to be the best alternative to estimate the LAAV of the investigated rocks.
Control de la actividad laboral, intimidad e Inteligencia Artificial
Authors: Carrizosa Prieto Esther
Published: February 2024

La inteligencia artificial ha irrumpido en el ámbito de las relaciones laborales de forma repentina, facilitando el ejercicio de los poderes empresariales y, en especial, las facultades de control y vigilancia de la prestación de servicios. La consolidación del uso de instrumentos y dispositivos para realizar esta función no ha ido acompañada del desarrollo o adaptación de las garantías necesarias para preservar el derecho a la intimidad de las personas trabajadoras. Es más, dichas garantías se habían venido debilitando de forma considerable desde el año 2006, de forma que en la actualidad la protección frente a dicha realidad se encuentra en la LOPD-GDD, que regula el derecho a la protección de datos y los derechos digitales de las personas trabajadoras, y en una doctrina constitucional que ha ido flexibilizando las exigencias del principio de proporcionalidad a la vez que lo conjugaba con la expectativa de privacidad. La consecuencia irremediable ha sido un debilitamiento del cuadro de garantías aplicables al derecho a la intimidad en un momento de auge e implantación de innovaciones tecnológicas potencialmente lesivas.
¿Un derecho penal delicuescente en una sociedad líquida?
Authors: Roso Cañadillas Raquel
Published: February 2024

Partiendo de un marco sociológico y filosófico-jurídico, en la primera parte del trabajo, se cuestiona el papel del Derecho penal en una sociedad líquida y las transformaciones a las que se expone al someterse a las necesidades de una sociedad demandante de seguridad caracterizada por la deslocalización, la temporalidad, la digitalidad, la volatilidad, cambios normativos vertiginosos sometidos a una constante caducidad y la exasperación de la incertidumbre y la incerteza. En la segunda parte del trabajo se ha tratado de aterrizar y contextualizar este marco sociológico y filosófico en el tratamiento de la cuestión de la legitimidad del Derecho penal de la mano de tres ejemplos, elegidos por su porosidad y sensibilidad a estos cambios sociales, como son el proceso de codificación, la posición de garante como categoría transversal en la teoría del delito y fundamentalmente como elemento del tipo y un sector del Derecho penal económico como es el Derecho penal del trabajo.

Oil fuels derived from fossils are non-renewable, so over time, they will run out and have a negative impact on air pollution. To overcome this, there is a need for environmentally friendly alternative fuels from renewable sources such as biodiesel. This research used microwave heating with a CaO catalyst. NaOH-impregnated snail shells and active carbon support. This research aims to determine the effect of power on the conversion of candlenut seed oil into biodiesel using the NaOH/CaO/CA catalyst both in terms of compliance with the SNI 7182-2015 standard and analysis using GC-MS (Gas Chromatography-Mass Spectrometry). The synthesis of the NaOH/CaO/CA catalyst was carried out through wet impregnation and calcination at a temperature of 500°C and analyzed using gas sorption analysis (GSA). Then proceed to the transesterification process, where the power for microwave heating was varied to 300, 450, and 600 watts with a mole ratio of esterified oil and methanol, namely 1:10 for 3 minutes. The analysis results of the NaOH/CaO/CA catalyst using the GSA instrument have a surface area of 9.306 m2/g, pore volume of 0.033 cc/g, and pore diameter of 14.043 nm. Meanwhile, the results of the biodiesel analysis showed that the optimum biodiesel yield was 85.625% at 600 watts of power and had a kinematic density and viscosity that met the SNI 7182-2015 biodiesel standards. Analysis of biodiesel characteristics using GC-MS showed that the three most optimum biodiesel components were hexadecanoic acid, methyl ester (22.664%), 9,12-Octadedecadienoic acid (Z,Z)-, methyl ester (30.176%) and 9-Octadecenoic acid (Z)-, methyl ester (38.656%).

Objectives

Type 2 diabetes (T2DM) is associated with increased risk for cardiovascular disease (CVD). Whether screen-detected T2DM, based on fasting plasma glucose (FPG) or on HbA1c, are associated with different risks of incident CVD in high-risk populations and which one is preferable for diabetes screening in these populations, remains unclear.

Methods

A total of 8,274 high-risk CVD participants were included from the UCC-SMART cohort. Participants were divided into groups based on prior T2DM diagnosis, and combinations of elevated/non-elevated FPG and HbA1c (cut-offs at 7 mmol/L and 48 mmol/mol, respectively): Group 0: known T2DM; group 1: elevated FPG/HbA1c; group 2: elevated FPG, non-elevated HbA1c; group 3: non-elevated FPG, elevated HbA1c; group 1 + 2: elevated FPG, regardless of HbA1c; group 1 + 3: elevated HbA1c, regardless of FPG; and group 4 (reference), non-elevated FPG/HbA1c.

Results

During a median follow-up of 6.3 years (IQR 3.3–9.8), 712 cardiovascular events occurred. Compared to the reference (group 4), group 0 was at increased risk (HR 1.40; 95 % CI 1.16–1.68), but group 1 (HR 1.16; 95 % CI 0.62–2.18), 2 (HR 1.18; 95 % CI 0.84–1.67), 3 (HR 0.61; 95 % CI 0.15–2.44), 1 + 2 (HR 1.17; 95 % CI 0.86–1.59) and 1 + 3 (HR 1.01; 95 % CI 0.57–1.79) were not. However, spline interpolation showed a linearly increasing risk with increasing HbA1c/FPG, but did not allow for identification of other cut-off points.

Conclusions

Based on current cut-offs, FPG and HbA1c at screening were equally related to incident CVD in high-risk populations without known T2DM. Hence, neither FPG, nor HbA1c, is preferential for diabetes screening in this population with respect to risk of incident CVD.
The origin of {113}<361> grains and their impact on secondary recrystallization in producing ultra-thin grain-oriented electrical steel
Authors: Liang Ruiyang , Li Qingchun , Ling Shuo
Published: February 2024

Ultra-thin grain-oriented electrical steel with a thickness of 80 µm is produced by one-step-rolling with industrial grain-oriented electrical steel. The research employs electron back-scattering texture analysis technique to investigate the evolution of deformation and recrystallization textures in this specific steel. Emphasis is placed on examining the origin of {113}<361> grains and their consequential impact on secondary recrystallization. It is revealed that primary, secondary, and tertiary recrystallization phases are integral during the annealing process. The origin of surface {113}<361> grains were result of initial deviated Goss grains with specific shear deformation behavior in cold rolled ultra-thin strips. Additionally, the influence of these grains on texture evolution is predominantly evident during secondary recrystallization. These grains potentially undergo abnormal growth in secondary recrystallization, exploiting high-energy grain boundaries among Goss grains. This phenomenon consequently leads to the diminution of the sharp Goss texture formed during primary recrystallization. Given the magnetic properties and predominant applications of ultra-thin grain-oriented electrical steel in medium-frequency fields, it is recommended to prepare ultra-thin grain-oriented steel during primary recrystallization phase.

Objectives

Emerging evidence points to tobacco experimentation being associated with a vast array of mental disorders, particularly anxiety and depression. We aimed to assess the prevalence of tobacco experimentation, its predictive factors and its potential links with anxiety and depressive disorders among in school adolescents in a Tunisian delegation.

Methods

We carried out a cross sectional study among adolescents schooling in middle and high schools in the delegation of Nfidha, Sousse, Tunisia, during the period from January to March of the 2019–2020 school year using an anonymous questionnaire self-administered to a representative sample of 1,353 randomly selected pupils. Data were collected using the Arabic versions of the Beck Depression Inventory short form (13 items) and the Screen for Child Anxiety Related Disorders (SCARED-C) and a socio-demographic questionnaire with reference to the literature.

Results

Tobacco was experimented by (17.5 %; CI 95 %: 14.8–18.8 %) of pupils. Almost three out of four pupils (73.2 %; CI 95 %: 70.8–75.6 %) reported experiencing depressive symptoms and (65 %; CI 95 %: 62.5–67.5 %) anxiety symptoms. Pupils who exhibited depressive disorder indicators were significantly more prone to experiment with tobacco (20.2 vs. 9.9 %, p<0.001; crude OR=2.301 CI 95 %: 1.74–3.58). Similarly, the prevalence of tobacco experimentation was found to be higher among pupils who reported having experienced anxiety disorders (21.0 vs. 14.5 %, p<0.001; crude OR=1.56 CI 95 %: 1.06–2.27). Being a male pupil (AOR=5.48 95 % CI: 3.62–8.31), being be enrolled in a high school (AOR=2.86, 95 % CI: 1.92–4.26), tobacco use by father and siblings (respectively AOR=1.76, 95 % CI: 1.19–2.60; AOR=2.47, 95 % CI: 1.52–4.02) and experiencing depressive disorders (AOR=2.69, 95 % CI: 1.60–4.53) were the determinants of tobacco experimentation in the multivariate analysis.

Conclusions

Tobacco experimentation in adolescence has been shown to be significantly associated with anxiety and depression. National smoking prevention strategies should be reinforced with a focus on mental health disorders.

Published: February 2024

In the study of TAVR, 3-dimensional (3D) printed aortic root models and pulsatile simulators were used for simulation training and teaching before procedures. The study was carried out in the following three parts: (1) experts were selected and equally divided into the 3D-printed simulation group and the non-3D-printed simulation group to conduct four times of TAVR, respectively; (2) another 10 experts and 10 young proceduralists were selected to accomplish three times of TAVR simulations; (3) overall, all the doctors were organized to complete a specific questionnaire, to evaluate the training and teaching effect of 3D printed simulations. For the 3D-printed simulation group, six proceduralists had a less crossing-valve time (8.3 ± 2.1 min vs 11.8 ± 2.7 min, P < 0.001) and total operation time (102.7 ± 15.3 min vs 137.7 ± 15.4 min, P < 0.001). In addition, the results showed that the median crossing-valve time and the total time required were significantly reduced in both the expert group and the young proceduralist group (all P<0.001). The results of the questionnaire showed that 3D-printed simulation training could enhance the understanding of anatomical structure and improve technical skills. Overall, cardiovascular 3D printing may play an important role in assisting TAVR, which can shorten the operation time and reduce potential complications.
Effect of struvite on the growth of green beans on Mars and Moon regolith simulants
Authors: Wamelink Wieger , Pouwels Charlotte
Published: February 2024

When humans are going to live on the Moon or Mars, food production and reusing waste products as manure will be essential for their survival. This calls for a circular sustainable agricultural ecosystem for food production. Earlier experiments have shown that crop growth is possible on simulant regoliths though there are several challenges. One of them is the shortage of nitrate or ammonium in the regoliths. Moreover, phosphate is not easily available. This could be solved by the application of human feces as manure. The goal of this experiment was to test if human urine-based struvite (MgNH4PO4) could fertilize Mars and Moon regolith simulants and lead to a higher yield of green beans. Three “soils” were examined: Mars regolith simulant (MMS), Moon regolith simulant (JSC 1A), and Earth potting soil with and without struvite. Forty grams of struvite were added, besides 10% (volume) organic matter. The experiment was conducted in tenfold. Length of plants was recorded, and beans were harvested when ripe and at the end of the experiment, three and a half months after the start. The struvite treatment yielded a significantly higher bean harvest. Plants on potting soil and Moon soil simulant with struvite addition reached the same height and were higher than the control plants. The plants on Mars soil simulant were smaller but still taller than the control. It can be concluded that the addition of struvite had a significant positive effect on the production of green beans on potting soil and Mars and Moon soil simulant.

Verbascum sinaiticum is locally used to treat wound, stomachache, viral infection, cancer, sunstroke fever, abdominal colic, diarrhea, hemorrhage, anthrax, and hepatitis. The objective of this study was to identify the compounds and to evaluate the antimicrobial and antioxidant activity of the extracts and isolated compounds from V. sinaiticum. The 1H-NMR, 13C-NMR, and DEPT-135 were used to elucidate the structures of isolated compounds. Essential oils were extracted by hydrodistillation method and their chemical analyses were performed by GC-MS. The broth microdilution method was used to evaluate the antimicrobial activity. The radical scavenging activity of the extracts and isolated compounds were evaluated using DPPH method. Silica gel column chromatographic separation of root extracts afforded seven known compounds: 3′-(4′′-methoxy phenyl)-3′-oxo-propionyl hexadecanoate (1), harpagoside (2), pulverulentoside I (3), scrophuloside B4 (4), scropolioside A (5), scropolioside-D2 (6), and harpagide 6-O-β-glucoside (7), which are all reported from this species for the first time. The EO extracts from leaves and roots were the most susceptible to Streptococcus agalactiae, with a 2 mg/mL MIC. The EO from roots was effective against Candida albicans and Trichophyton mentagrophytes, with a MIC of 8 mg/mL. The MeOH and CH2Cl2/CH3OH (1:1) root extracts showed the maximum activity against S. epidermidis with MIC values of 0.25 mg/mL. The strongest antibacterial effects were demonstrated against Staphylococcus epidermidis, which exhibited a 0.0625 mg/mL MIC for compound 1. The strongest radical scavenging activity was exhibited by the methanol extract (IC50 = 3.4 μg/mL), and compounds 4, 6, 5, 3, 7, and 2 with IC50 values of 3.2, 3.38, 3.6, 3.8, 4.2, and 4.7 μg/mL, respectively, in comparison with ascorbic acid (IC50 = 1.3 μg/mL). The results of the molecular docking analysis of compounds revealed minimal binding energies range from −38.5 to −43.1 kJ/mol, −33.1 to −42.7 kJ/mol, −34.7 to −39.3.7 kJ/mol, −25.5 to −37.6 kJ/mol against human myeloperoxidase (PDB ID: 1DNU), murA enzyme (PDB ID: 1UAE), human topoisomerase IIβ (PDB ID: 4fm9), S. epidermidis FtsZ (PDB number: 4M8I) proteins, respectively. The docking results and the in vitro antibacterial activity are in good agreement. These findings show that the isolated compounds 2–7 can act as potential antioxidants and strong antibacterials against Staphylococcus aureus and S. epidermidis. As a result, V. sinaiticum root extracts have the potential to be effective in treating diseases caused by bacteria and free radicals, as long as further investigation has been suggested for the ultimate decision of this plant’s potential candidate.
“Knees Out” or “Knees In”? Volitional Lateral vs. Medial Hip Rotation During Barbell Squats
Authors: Chiu Loren Z.F.
Published: February 2024

Chiu, LZF. “Knees out” or “Knees in”? Volitional lateral versus medial hip rotation during barbell squats. J Strength Cond Res 38(3): 435–443, 2024—Medial or lateral hip rotation may be present during barbell squats, which could affect the hip frontal and transverse plane moments. Male (n = 14) and female (n = 18) subjects performed squats using their normal technique and with volitional medial and lateral hip rotation. Hip net joint moments (NJM) were calculated from 3-dimensional motion capture and force platform measurements. Statistical significance was set for omnibus tests (α = 0.05) and Bonferroni’s corrected for pairwise comparisons (α

t-test = 0.0056). Normal squats required hip extensor, adductor, and lateral rotator NJM. Lateral rotation squats had smaller hip extensor (p = 0.002) and lateral rotator (p < 0.001) NJM and larger hip adductor (p < 0.001) NJM than normal squats. Medial rotation squats had smaller hip extensor (p = 0.002) and adductor (p < 0.001) NJM and larger hip lateral rotator (p < 0.001) NJM than normal squats. These differences exceeded the minimum effects worth detecting. As gluteus maximus exerts hip extensor and lateral rotator moments, and the adductor magnus exerts hip extensor and adductor moments, these muscles combined would be required to meet these hip demands, supporting previous research that has established these muscles as the primary contributors to the hip extensor NJM. Lateral rotation squats reduce hip lateral rotator and increase hip adductor NJM, which may be hypothesized as preferentially loading adductor magnus. Medial rotation squats increase hip lateral rotator and decrease hip adductor NJM; therefore, this variant may shift loading to the gluteus maximus.
Analysis of Effects of Test Temperature on the Notch Strength of High-Strength Sheet Alloys
Authors: Weiss Volker , Sessler John G.
Published: February 2024

The notch properties of four high-strength sheet alloys are analyzed as a function of test temperature. For the particular heat treatments employed, three of the alloys (300 M, Vascojet 1000, and Ti-13V-11Cr-3Al) exhibit a sudden loss in notch strength with decreasing test temperature. The temperature of this transition, which reflects an inherent loss in ductility, is also found to depend upon the stress state—in particular, the stress biaxiality at the notch root as indicated by the ratio of thickness to root radius. The apparent dependence of transition temperature on the stress concentration factor appears to be a secondary effect. The fourth alloy, Ti-4Al-3Mo-1V, does not exhibit a transition at temperatures down to −320 F, even for high stress-concentration factors. Nevertheless, a loss in notch ductility for all test temperatures is observed with increasing biaxiality at the notch root for thickness to root radius ratios larger than about 10. A new quantity, the notch ductility ratio, appears to be an extremely useful parameter in the analysis of notch tensile strength data.

Authors: Markovich R. , Schwartzberg F.
Published: February 2024

Facilities for performing mechanical property testing and structural component testing at cryogenic temperatures, particularly liquid hydrogen temperature (−423 F), are described. Preliminary uniaxial test results obtained in the mechanical property program indicate that the aluminum alloys 2014-T6, 6061-T6, 5456-H24, and 2219-T81 should behave satisfactorily in liquid hydrogen service. Unnotched, notched, and weld properties are given. Biaxially loaded structural component tests of parent metal showed good agreement with uniaxial tests. The results of welded specimen testing, however, showed a significant decrease in strength compared to uniaxial test results, due to residual stresses. Biaxial stress-strain curves are given for several lightweight metals.

The main features, the advantages and the applicability of some examples of each approach are discussed. The need to consider the effects of material strength level, fracture initiation versus propagation behaviors, specimen and defect dimensions, and plastic deformation on the test results and their relation to the selection of design parameters are indicated.
Applicator Considerations in Glazing
Authors: Collyer N. S.
Published: February 2024

The problems and concerns of a sealant applicator in glazing work are somewhat vague and uncertain rather than scientifically exact and subject to precise controls. It is the uncertainties of weather, job conditions, personnel, variations of materials, and other factors at least partially beyond the control of the applicator that make the applicator's task difficult and which, in turn, make it difficult to define accurately the applicator's concerns. This paper cannot possibly define and explain each variable because the variables are endless. It will identify some of the more common problems and attempt briefly to explain how these problems affect the applicator's work.

Authors: Grieve E. E.
Published: February 2024

Modern construction places higher demands on glazed openings. The proper selection of sealants and their application are required for satisfactory performance. There are options available in Class II sealants both in proven performers and newer products with good characteristics. Advantages and disadvantages should be considered when determining which generic type, the need for surface conditioners, the method of application, and the labor costs involved. Consideration must be given to the type of framing member specified. Tolerances should be reviewed as they relate to the glazing reglet. Sealant failures should be analyzed to avoid repeating costly errors. There is a need to tighten specifications so as to concentrate and define responsibility in such a way that there can be little question as to the performance expected.

Structural Aspects of Lock-Strip Gasket Glazing
Authors: Oberdick W. A.
Published: February 2024

Correlation studies between mock-up tests of lock-strip gasketed walls and unit push-out tests indicate a basis of developing an engineering approach to structural design paralleling the structural design procedures used for selecting glass. An exploration of the application of a lock-strip gasket for solar collectors suggests that design criteria should be determined from a statistical study of solar-climatic weather data. Further, the application of the unit-test approach will permit preliminary evaluation of new design concepts.

Published: February 2024

White-rot fungi are vital microorganisms that can decay lignocellulosic biomass. This study investigated the ability of white-rot fungus found on rotten wood to produce ligninolytic enzymes and their enhancement using nanoparticles (NPs). Phanerochaete chrysosporium was isolated from decayed wood. Its ability to produce ligninolytic enzymes, namely CMCase, FPase, Laccase, and MnPase, was recorded. The enzymes’ productivity was enhanced via utilization of the surfactant polysorbate 80 with optimum concentration 0.20 mL/L for maximum CMCase (201.33 ± 2.31 U/mL) and FPase (66.33 ± 0.58 U/mL), whereas the corresponding value was 0.15 mL/L for laccase and MnPase production. Mn2O3NPs and CuONPs enhanced the enzymes’ productivity but with different levels according to their concentrations, where the maximum productivity of CMCase (220.67 ± 2.31 U/mL) and (FPase 74.63 ± 3.51 U/mL) were at 50 ppm, but MnPase (0.52 ± 0.01 U/mL) and laccase (2.88 ± 0.01U/mL) were at 25 ppm and 75 ppm of CuONPs, respectively. Mn2O3NPs at 75 ppm enhanced the productivity of CMCase (219.33 ± 1.15 U/mL) and FPase (74.63 ± 3.51U/mL); but at 25 ppm and 75 ppm enhanced the productivity of laccase (2.40 ± 0.04U/mL) and MnPase (0.73 ± 0.03 U/mL), respectively. Thus, NPs were found to play a vital role in improving the productivity of ligninolytic enzymes.

Published: February 2024

Objective- The basic aim or objective of this study is to investigate the impact of implementing technology brand reputation and the university's external image on the student’s adoption to change. Based on the social identity theory this research recommends that implementing technology with brand reputation and university external image may induce their students to adopt these technologies. It is further argued that the effect of these factors also depend on the student’s university identification and their culture. Methodology/ design/approach - This study used the convenience sampling method for collecting the data from the 370 students of the educational sector in Pakistan during the implementation of new online technology systems. The model of this study was tested by using the structure equation modeling technique in Amos. Findings- The analysis of this study suggests that implementing technology brand reputation and the university external image positively increased the student’s adoption to change and their relationship is also importance for the better performance of university when student’s deification with the university are high and when they are loyal to their institution then they easily adopt the changes whatever technology is being implement in their institution. Value/originality - In this latest ere of research, technology play an important role in educational sector for different activities or most popularly for online classes during an epidemic situation which is need to study the role of brand reputation and university image in the student identification and adoption behavior. The study fills this gap and has two main contributions: one is how reputation of technological brand which is implementing in the university and their external image play a role in student adoption for change perspectives and second is how social identity perspective model leads students to quickly adopt this technological change.
A Method to Classify Users on Social Networks Based on Similarity Mesuring
Authors: Nguyen Thi Hoi,
Published: February 2024

With the express growth of social networks, users have joined more and more of these networks and live their lives virtually. Consequently, they create huge amounts of data on these social networks: their profile, interests, and behaviors such as posting, commenting, liking, joining groups or communities, etc. One of the basic issues in these challenges is the problem of estimating the similarity among users on these social networks based on their profile, interests, and behavior. This paper presents a model for estimating the similarity between users based ontheir behavior on social networks. The considered behaviors are activities including posting or sharing entries, liking these entries, commenting and liking the comments in these entries, and joining a group in the social networks. The model is then evaluated with a dataset collected from Facebook users. The results show that the model correctly estimates the similarity among users in the majority of cases.

Emotionally intelligent medical students have an awareness about how to respond in a particular situation, they considered the pros and cons before giving response whereas the medical students who are low on the scale of emotional intelligence may react in an absurd way such as being anger and violent. Objectives: This study aimed to investigate the interplay between emotional intelligence (EQ), anger, and violent behavior among medical students. Specifically, it sought to analyze the association between emotional intelligence levels and the expression of anger and violence, as well as to compare emotional intelligence and aggression tendencies between male and female students. Methods: A correlational research design was employed, utilizing online surveys as the data collection method. A total of 200 medical students aged between 19 to 30 years participated in the study. Emotional intelligence, anger expression, and violent behavior were measured using standardized scales. Statistical analyses including descriptive statistics, Pearson correlation, and independent sample t-tests were conducted using SPSS 23.0 software. Results: The findings revealed a significant negative correlation between emotional intelligence and both anger expression and violent behavior. Male students exhibited higher levels of anger and violent behavior compared to female students. Emotional intelligence scores were lower in male students, indicating a potential contributing factor to their heightened aggression tendencies. Conclusion: The study provides empirical evidence supporting the association between emotional intelligence, anger, and violence in medical students. Lower emotional intelligence levels were linked to increased anger expression and violent behavior. These findings underscore the importance of integrating emotional intelligence education programs into medical curricula to mitigate aggression tendencies and promote healthier interpersonal relationships among students.
Factors Influencing Tax Declaration Decisions on Social Networks of Online Retailers in Vietnam

Published: February 2024

The growth of e-commerce and online retail in Vietnam, particularly on social networks, has presented challenges for the government’s tax authorities. Preventing tax loss through inspections can be difficult due to missing or incomplete taxpayer data from transaction processing servers. Explaining undeclared or incompletely declared revenue in online trading transactions on the server or the Internet can be challenging, especially for retail activities and service provision for businesses and individuals selling on social networking. In Vietnam, the Tax Management Law 2019 established the tax rates online retailers must pay. However, tax collection for social network retailers still depends on tax authorities encouraging them to self-declare their revenue. Current research and practice show that very few sellers on social networks participate in the self-declaration of revenue to pay taxes. Moreover, few studies focus on factors affecting the participation of online retailers in Vietnam in tax declaration and payment, especially those selling on social networks, and most lack a solid theoretical foundation. Through a review of related studies, this research has identified several factors that affect tax payment decisions for retailers on social networks in Vietnam. The study also provides several recommendations to promote and enhance retailers’ tax declaration and payment decisions on social networks in Vietnam.
A TB free India is far away
Authors: Kanmony Dr J Cyril
Published: February 2024

TB is a major health issue in many countries including India. In India, the burden of TB is the highest and the number of drug resistant TB (DR-TB) cases is very high. But there is an acute shortage of drugs for treating the DR-TB. The world is not able to eliminate TB due to the infections caused by antimicrobial resistance. The resistance is caused by repeated or continuous use of antibiotics. It is advised by the WHO that there should be limited prescriptions from the ‘Watch” and ‘Reserve’ categories. But in India more than 50% of the antibiotics prescribed are from the ‘Watch’ group. Resistance results in the mutation of single-cell pathogens and the mutated pathogens have evolved their own defence mechanisms to inactivate or evade the drugs. But there is limited/no development of new antibiotics to combat antimicrobial resistance, particularly DR-TB. The total investment made in R&D on antibiotics by major companies is only 17.5% of the total revenue. In India, to eradicate TB the Health Ministry rolled out the National Strategic Plan (NSP) 2017–2025, which aims at increasing the number of individuals who have been undergone precision test from 0.04 million to 13.4 million in 2022. Instead of this target the achieved number is only 4.1 million. And so a new strategic plan 2020 – 2025 was launched; the revised NSP has raised the bar even further. But in India, there are only limited facilities to conduct the precision test and so India is not able to achieve even the diagnostic target. The reasons for this state of affairs are: poor quality/non-availability of drugs, delayed treatment/missing TB cases (there are a few millions of non-notified TB patients in the private sector) and high load of drug resistant pathogens. There are also a number of other vulnerable groups of people who have to be tested immediately with presumptive TB. All these mean that India requires huge resources to combat TB. But in India resources available are very limited. It means that India failed in all aspects and so no one can expect a TB-free India even in 2030 without a comprehensive multifaceted approach.
The Sensitivity and Specificity of Procalcitonin in Diagnosing Bacterial Sepsis in Neonates
Authors: Beaumont Rachael , Tang Kailey , Gwee Amanda
Published: February 2024

CONTEXT AND OBJECTIVES

Neonatal sepsis accounts for 15% of all neonatal deaths. Early detection enables prompt administration of antibiotic treatment, reducing morbidity and mortality. This study aims to review the sensitivity and specificity of procalcitonin in diagnosing microbiologically-proven sepsis in neonates to determine the optimal procalcitonin cut-off value for use in clinical practice.

DATA SOURCES, STUDY SELECTION, AND DATA EXTRACTION

Medline, EMBASE and PubMed were searched on 3 May 2023 for original studies in symptomatic neonates in whom both blood culture and procalcitonin levels were taken, and a procalcitonin cut-off with either sensitivity or specificity reported. Studies that included asymptomatic or culture-negative neonates in the proven sepsis group were excluded. Risk of bias was assessed using the Qualitative Assessment of Diagnostic Accuracy Studies 2 tool.

RESULTS

Nineteen original studies enrolling a total of 1920 symptomatic neonates (721 with proven sepsis) were included. Six studies used a procalcitonin cut-off of 0.5 ng/mL and found a sensitivity of 87% to 100% and specificity of 17% to 89%. Nine studies evaluated higher procalcitonin cut-off values between 0.99 ng/mL and 2 ng/mL, which were 67% to 98% sensitive and 41% to 89% specific. All other procalcitonin thresholds were neither sensitive nor specific. Meta-analysis was not performed because of high risk of bias within the identified studies.

CONCLUSIONS

This review found that procalcitonin was highly sensitive (87% to 100%) at a cut-off value of 0.5 ng/mL, although specificity varied greatly across all cut-off values reviewed. The variation in diagnostic accuracy between studies suggests that procalcitonin may be useful to guide antibiotic cessation but should not be used alone as a diagnostic marker for neonatal sepsis.

En este número especial, se recogen testimonios y estudios que confirman la poliédrica figura de Emilia Prieto Tugores, así como la amalgama de creación y pensamiento que la constituye: pintora, folclorista, compositora e intérprete, feminista, grabadora, periodista, escritora, humorista gráfica, maestra, activista. Por un lado, se examinan las objeciones, entonces pioneras, que ella hacía al papel de la mujer en la sociedad y la política costarricenses mediante ensayos y grabados de la revista nacional Repertorio Americano. Más adelante, se reflexiona sobre el proceso que condujo a la edición, a inicios de la década de 1990, de 25 canciones ticomeseteñas recopiladas por la maestra Prieto. También se incluye un análisis crítico a propósito de la voluntad contestataria de la investigación sónica de la folclorista. Estos estudios van acompañados por la edición de las canciones “Por ‘ónde pongo el dulce?” y “Fernando el francés”, recopiladas por ella.

Authors: Freitas Patrícia Oliveira de , Dryzun André Aron Pastore , Passone Eric Ferdinando
Published: February 2024

O artigo apresenta os princípios norteadores para a atuação do psicólogo escolar, tendo como objetivo sistematizar as recomendações advindas de documentos oficiais do Conselho Federal de Psicologia (CFP) e Conselho Regional de Psicologia de São Paulo (CRP-SP), no que se refere às práticas dos profissionais de psicologia no âmbito escolar. Optou-se pela realização de uma análise documental, tendo sido selecionados quatro materiais oficiais de referência do trabalho do psicólogo no âmbito educacional, sendo eles: um que trata da relação entre psicologia e educação e suas possíveis contribuições à prática profissional do CRP-SP; um caderno temático sobre a psicologia frente às demandas escolares e intersetorialidade do CRP-SP; um documento de referências técnicas para profissionais de psicologia no que se refere à educação básica do CFP em conjunto com o Centro de Referência Técnica em Psicologia e Políticas Públicas (CREPOP); e, por último, um referente a uma nota técnica acerca do enfrentamento da violência nas escolas do CFP. Os documentos selecionados abordaram diversas contribuições à prática profissional do psicólogo no âmbito educacional, destacando-se uma maior abrangência no cuidado aos estudantes ao conceber caminhos intersetoriais e a necessidade em adentrar ao âmbito das políticas públicas para se atuar de maneira mais consciente e coesa.

We present the case report of a 24-day-old infant admitted to the Department of Paediatric Surgery in order to treat suspected obstruction of the gastrointestinal tract. For two days prior, the patient had experienced gas and stool retention. On the day of admission, vomiting occurred with gastric contents, later followed by faecal. Ultrasound and scout film of the abdomen were performed, showing radiological features of obstruction of the gastrointestinal tract. The newborn was urgently referred for surgery. The procedure was performed under general anaesthesia. Intraoperatively, at the level of the ileum, 5 cm before the cecum, obstruction of the gastrointestinal tract was found in the form of a lesion resembling Meckel’s diverticulum. Resection of the lesion was performed and end-to-end ileoileal anastomosis was formed. The resected lesion was sent for histopathological examination, which revealed a cystic duplication of the gastrointestinal tract.
