Published: November 2023

El objetivo de este trabajo es analizar la estrategia de asociación de una empresa en condiciones estables, para tratar de rescatar a otras empresas por la incertidumbre ocasionada por la pandemia del COVID-19. Para este análisis relacionamos los conceptos de utilidad esperada, riesgo, incertidumbre y teoría de juegos, donde el factor riesgo se desprende por la asociación con empresas en posible fracaso, y el factor incertidumbre por la falta de conocimiento respecto a las empresas a asociar. Los resultados muestran que las condiciones por asociar son distintas, dependiendo si el objetivo es económico o de precaución. La aportación del trabajo es analizar metodológicamente el concepto de precaución, derivado de la pandemia, que muestran las empresas cuando deciden asociarse. A pesar de que el trabajo no considera información y condiciones reales de la pandemia, el trabajo concluye y recomienda que si las empresas decidieran anexarse, para abarcar más mercado o recuperarse, tendrían que considerar factores de riesgo e incertidumbre.
Investigating the Culture Around Sexual Harassment in First-Generation Universities in Southwestern Nigeria: Protocol for a Mixed Methods Study
Authors: Mapayi Boladale , Oloniniyi Ibidun , Oginni Olakunle , Harrison Abigail
Published: November 2023

Background

The phenomenon of sexual harassment (SH) is a complex issue with multiple prongs that concerns all members of academia and raises serious challenges, particularly regarding prevention and response. SH in tertiary institutions remains a huge problem worldwide, leading to severe emotional, academic, and career difficulties, as well as undue suffering. Institutions have responded in various ways to alleviate the burden of SH with little success, especially in Nigeria. The prevalence is high but reportage is low because of the culture of silence around SH in most educational institutions. This study aims to identify factors associated with SH in tertiary institutions in Nigeria and explore factors surrounding reportage or nonreportage following the experience of SH, the institutional mechanisms to prevent and respond to SH, and the lived experience of survivors of SH.

Objective

The objective of this study was to present a study protocol that is designed to identify factors associated with the experience of SH in tertiary institutions in Nigeria, the institutional mechanisms to prevent and respond to SH, and the lived experience of survivors of SH.

Methods

A mixed (quantitative and qualitative) methods approach is used consisting of a policy review of existing antisexual harassment policies in the selected universities, a quantitative survey to determine the correlates of SH, focus group discussions to explore the perspectives of the university community concerning SH, in-depth interviews to explore the lived experiences of survivors of SH, and key informant interviews to understand the perspectives of people who provide interventions to survivors.

Results

This study was funded in July 2022 by the Consortium for Advanced Research Training in Africa, and data collection started in November 2022. The SH policies were comprehensive, with clear policy statements and definitions, and recognized a wide range of survivors and perpetrators. However, there was no clear mention of prevention and response to same-sex SH. Lived experiences showed negative psychological and social sequelae and little institutional support.

Conclusions

This is the first study that has a component investigating same-sex SH in tertiary institutions in Nigeria. This is also one of the first studies to explore the lived experiences of survivors of SH in Nigerian universities. The findings from this study suggest that periodic evaluation of SH policy implementation will improve institutional support, thus creating safe spaces for survivors and will thereby encourage reportage and support; prevention and response strategies need to be more inclusive; and more interventions should focus on strengthening prosocial skills and healthy, equitable relationships.

Diagnostic Accuracy of Single-Lead Electrocardiograms Using the Kardia Mobile App and the Apple Watch 4: Validation Study
Authors: Klier Kristina , Koch Lucas , Graf Lisa , Schinköthe Timo , Schmidt Annette
Published: November 2023

Background

To date, the 12-lead electrocardiogram (ECG) is the gold standard for cardiological diagnosis in clinical settings. With the advancements in technology, a growing number of smartphone apps and gadgets for recording, visualizing, and evaluating physical performance as well as health data is available. Although this new smart technology is innovative and time- and cost-efficient, less is known about its diagnostic accuracy and reliability.

Objective

This study aimed to examine the agreement between the mobile single-lead ECG measurements of the Kardia Mobile App and the Apple Watch 4 compared to the 12-lead gold standard ECG in healthy adults under laboratory conditions. Furthermore, it assessed whether the measurement error of the devices increases with an increasing heart rate.

Methods

This study was designed as a prospective quasi-experimental 1-sample measurement, in which no randomization of the sampling was carried out. In total, ECGs at rest from 81 participants (average age 24.89, SD 8.58 years; n=58, 72% male) were recorded and statistically analyzed. Bland-Altman plots were created to graphically illustrate measurement differences. To analyze the agreement between the single-lead ECGs and the 12-lead ECG, Pearson correlation coefficient (r) and Lin concordance correlation coefficient (CCCLin) were calculated.

Results

The results showed a higher agreement for the Apple Watch (mean deviation QT: 6.85%; QT interval corrected for heart rate using Fridericia formula [QTcF]: 7.43%) than Kardia Mobile (mean deviation QT: 9.53%; QTcF: 9.78%) even if both tend to underestimate QT and QTcF intervals. For Kardia Mobile, the QT and QTcF intervals correlated significantly with the gold standard (rQT=0.857 and rQTcF=0.727; P<.001). CCCLin corresponded to an almost complete heuristic agreement for the QT interval (0.835), whereas the QTcF interval was in the range of strong agreement (0.682). Further, for the Apple Watch, Pearson correlations were highly significant and in the range of a large effect (rQT=0.793 and rQTcF=0.649; P<.001). CCCLin corresponded to a strong heuristic agreement for both the QT (0.779) and QTcF (0.615) intervals. A small negative correlation between the measurement error and increasing heart rate could be found of each the devices and the reference.

Conclusions

Smart technology seems to be a promising and reliable approach for nonclinical health monitoring. Further research is needed to broaden the evidence regarding its validity and usability in different target groups.
Development and Testing of an Electronic Diabetes Diary Integrated With a Hospital Information System for Individuals With Type 2 Diabetes Mellitus: Protocol for a Mixed Methods Study
Authors: Skaria Geena , Reshmi Bhageerathy , K M Sabu , Shetty Sahana , Lakshmi R Vani
Published: November 2023

Background

Type 2 diabetes mellitus (T2DM) is one of the leading noncommunicable diseases that require diabetes self-management (DSM) practices. This study proposes to develop a customized mobile health (mHealth) app integrated with a hospital information system (HIS) to enable real-time, two-way transfer of information between the patient and physician. The captured information in the electronic health record will facilitate physicians to have a chronological account of the patient’s diabetes history and enable tweaking of the treatment.

Objective

The objectives of the study are (1) to develop the HIS-integrated Electronic Diabetes Diary (EDDy) per the end-user expectations at a tertiary care hospital in a south Indian state with a high prevalence of T2DM and (2) to evaluate and test adherence to EDDy in the management of T2DM.

Methods

The study will be carried out in 3 phases. Phase 1 involved in-depth interviews with primary end users to gather information regarding their expectations from the hospital-based EDDy. Phase 2 will use this information to develop a customized mHealth app using an iterative model of software development. Phase 3 will involve a pre- and posttest design; the developed app will be tested among consenting patients, where physicians will receive the patients’ data through the HIS-integrated mHealth app. The pre- and posttest values will be analyzed for adherence leading to improvement in patients’ self-management of blood glucose, user experience, glycemic control, and clinical utility.

Results

Phase 1 was completed on November 28, 2023. Phase 2 commenced in December 2023 and will end in May 2025. Phase 3 will follow afterward.

Conclusions

The proposed app will include a convenient and simple alert system that enables the patient to test glucose values at self-selected intervals, provide grading options to enter diabetic-related complications, enhance patients’ knowledge of tracking and managing the complications of diabetes, and help in maintaining the visual representation of glucose values and complications. The simplicity and usability of the modules are its novelty, which may motivate the patients to keep track of their glucose values and help them attain better health outcomes.

Published: November 2023

This study focused on geological and structural mapping of Pan-African Province of South Maradi by using the aeromagnetic and filed surveys. The study zone corresponds to the northern part of the Benin-Nigerian Shield, belonging to the Pan-African mobile zone in the East of West African Craton. Previous geological work dates from the 1970s and limited to the summary geological map. According to this work, basement formations crop out discontinuously and are not subject by a structural study. In addition, the use of this map reveals a problem of correlation between the geological contours described on the existing map and those observed in the field. A combined analysis of aeromagnetic and field data led to complete then correct the petrographic and structural gap existing in the previous summary geological map since 1970s, which allowed to produce a new geological and structural map of studied zone (South Maradi Pan-African province). Petrographic and structural analysis of this new map shows that the spatial distribution of geological formations is characterized by the alternating Schist Belts and mylonitic gneiss Shear zones associated with migmatites panels and granitoïd intrusions. Thus, the different petrographic facies mapped are represented by schists-micaschist, mylonitic gneiss, migmatitic gneiss and intrusive porphyric granites. Previous data revealed a petrographic and structural continuity between South Maradi Pan-African formations with those of contiguous Pan-African province of North Nigeria.

Authors: VERMA PREETI , PARMAR DHARMISHTHA , SUHAGIA BHANUBHAI
Published: November 2023

Objective: ‘Karira’ is a common Sanskrit name of an important Ayurvedic medicinal plant, Capparis decidua Edgew. (family, Capparidaceae). It is a bushy shrub or small tree distributed throughout the dry areas of India and other parts of the world. As per traditional literature, various parts of the plant are widely used in the treatment of biliousness, jaundice, andas a liver tonic. Therefore the present study was aimed at the evaluation of hepatoprotective activity of Karira stem.

Methods: For the study, three types of extracts of C. decidua stem were prepared, viz. aqueous extract, alcoholic extract and 50% hydroalcoholic extract. The stem extracts were evaluated for their protective effects against carbon tetrachloride-induced acute hepatotoxicity in the rats in in vivo conditions.

Results: The results suggested that among all the three extracts, specifically the alcoholic extract at the dose of 300 mg/kg exhibited highest hepatoprotective activity, which was comparable to the standard drug, silymarin (50 mg/kg). The hepatoprotective effects were further confirmed by detailed antioxidant study, which revealed significant free radical scavenging activities and protection against lipid peroxidation offered by the extracts, along with preservation of the integrity of liver cells as evident from the histopathological study of the liver tissues.

Conclusion: The present investigation supports the traditional use of Karira plant in liver-related disorders.

Authors: MUSFIQUE JABIN , TALUKDAR LEENA , BARMAN MANOJ
Published: November 2023

Objective: The aim of this study is to detect precancerous lesions and intraductal (in situ) malignancies in cytologically and radiologically diagnosed benign breast lesions and its prevalence in different age groups.

Methods: A total of 448 cases of breast lumps were diagnosed cytological as benign breast lesions in our cytology division from july 2022 to june 2023. Of these, 148 cases were available for histopathological examination.

Results: On Histopathology, 122 cases (82.4%) were diagnosed as benign lesions. 19 (12.8%) cases were found to harbour pre-malignant lesions, 06 (4.0%) cases as in-situ carcinomas and 1 (0.6%) case of encapsulated papillary carcinoma without invasion.

Conclusion: To conclude, prevention of development of carcinoma of breast is the key step to reduce the burden of morbidity and mortality. Recognising pre-malignant lesions can go a long way in reducing development of invasive carcinoma, for which histopathological examination is the most helpful tool. Thus any benign breast lesions that have been detected to harbour pre-malignant changes must be placed into a separate group than from purely benign breast lesions. These groups must be followed up and treated according to standard available protocols.

Authors: GOEL DIVYA
Published: November 2023

Objective: Berberine is an isoquinolone alkaloid present in many plants and reported to possess anti-diabetic, hypolipidemic, anti-cancer, anti-bacterial, anti-pyretic, antiviral and anti-inflammatory effects. In addition, berberine can modulate neurotransmitter like N-methyl-D-aspartate (NMDA), serotonin and Nitric Oxide, thus can produce anticonvulsant effect.

Methods: The seizures were induced in mice by maximal pentylenetetrazol and electroshock. The effect of root extract on seizures was compared with standard anticonvulsant agents, phenytoin and diazepam.

Results: Theroot extract of berberine aristata suppressed duration of tonic convulsions in maximal electroshock-induced seizures while it delayed time of onset of seizure as well as significantly decreased the duration of myoclonic-jerks-in pentylenetetrazol-induced seizures. Further, the study also indicated that the root extract of berberine aristata also produced motor impairment at the antiseizure doses.

Conclusion: The present study indicated that berberine exhibits anticonvulsant activity in both models and can be useful in epileptic patients.

Authors: SNEHA SHRUTI , RIGVEDA RICHA , SHARMA NALNEESH
Published: November 2023

Objective: Hypertensive disorders of pregnancy (HDP), including gestational hypertension, preeclampsia, and eclampsia, are a global concern due to their impact on maternal and fetal health. The epidemiological landscape of HDP in India, a diverse and populous nation, presents unique challenges influenced by healthcare disparities and cultural factors.

Methods: This cross-sectional study, conducted from Jul 1, 2018, to Jun 30, 2019, aimed to compare the spot urinary protein/creatinine ratio with the conventional 24 h urine protein collection method for proteinuria estimation in preeclamptic pregnant women. Ninety inpatients were included, adhering to specific inclusion and exclusion criteria. Data on demographics, blood pressure, liver function, and 24 h urine protein excretion were collected and analyzed statistically.

Results: The mean age of pregnant women with preeclampsia in India was 28.9 y (range: 18-33), with 45.55% primigravida and 65.55% multigravida. Diastolic blood pressure at admission was 94.98 mmHg±8.54, displaying variations compared to other studies, potentially influenced by genetic, dietary, and healthcare factors. Liver function test results indicated abnormal findings in 90% of cases for total bilirubin, 60% for alanine transaminase (ALT), and 60% for aspartate transaminase (AST), highlighting disparities in liver function when compared to prior research. Proteinuria levels demonstrated substantial variation, with the present study reporting a mean 24 h urine protein excretion of 1884 mg/d±2562, reflecting the complexity of proteinuria assessment across different populations and methodologies.

Conclusion: The epidemiology of HDP in India is intricate and multifactorial, influenced by diverse demographic factors, blood pressure levels, liver function, and proteinuria. Findings underscore the need for region-specific research and tailored healthcare interventions. Further investigations are essential to unravel the contributing factors to HDP in India and guide effective preventive measures and management strategies in this populous and diverse nation.

Afroamérica es el nombre que se le ha dado "al conjunto de regiones y comunidades que tienen raíz africana", producto de un "proceso de traslado masivo y forzado de millones de hombres, mujeres y niños que desde su llegada, a partir del siglo XVI, conformaron parte de la población americana". Los estudios sobre estas regiones y comunidades se han venido desarrollando a pesar de enfrentar múltiples dificultades y en los años recientes han experimentado en nuestra América un vigoroso impulso, en gran medida, provocado por la acción cada vez más consciente y militante de los afrodescendientes latinoamericanos. Estos trabajos, originalmente presentados como ponencias en el Segundo Coloquio Afroamérica. Historia, cultura y procesos identitarios, fueron seleccionados por su valor académico ya que aportan al conocimiento de los estudios afroamericanos un rico y variado conjunto de elementos sobre temas poco conocidos relativos a las diversas expresiones culturales de los afrodescendientes de diferentes países de nuestra América. Estos aportes abarcan un universo que no se restringe a un determinado orden teórico o metodológico, ni a un solo enfoque o perspectiva, sino a una diversidad de posturas, algunas de ellas muy novedosas dentro de las tendencias actuales de las ciencias sociales y las humanidades. Los diversos debates de las últimas tres o cuatro décadas sobre la diversidad cultural, étnica y racial de nuestros pueblos en las esferas de lo social, lo económico y lo político constituyen el rico y variado contexto en el que se inscriben las investigaciones que han dado origen a los estudios que aquí presentamos.
A Review on Different Types of Bridge Girders and Different Tendon Profiles
Authors: Shrivastava Arpit
Published: November 2023

Abstract: A bridge is a structure that allows traffic to cross over an obstruction without blocking the path below.The necessary passage may be for a pipeline, a canal, a road, a railroad, or pedestrians. The pre- stressed concrete bridges have excellent riding characteristics that reduce traffic vibrations, torsional rigidity, are less likely to crack early, have continuous spans, and are strong. However, the most notable feature is that the natural frequency of vibration hardly matches with vehicle frequency, leading to wide acceptance in freeways, flyovers on highways and in contemporary metro train systems. In order to obtain a structure that behaves at the level of life safety under powerful earthquakes, bridges must be able to endure both static and dynamic stresses, particularly earthquake-induced loads.
Effect of Eccentricity of Connection on Design of RC Columns
Authors: Kashyap Swaranjali
Published: November 2023

Abstract: This study investigates the influence of eccentricity on the behaviour of reinforced concrete (RC) beam-column connections, with a particular focus on moment distribution, and structural analysis conducted on 5 story buildings of different eccentricity using STAAD Pro. The study employed computational simulations to assess how different levels of eccentricity affect the moment distribution within the connection region. STAAD Pro was used for numerical modelling and analysis. The outcomes of this research are expected to enhance the understanding of the complex behaviour of RC beam-column connections and serve as a valuable resource for structural engineers and designers. Ultimately, this knowledge can be utilized to optimize the design and construction of structures to ensure they meet safety and performance standards, particularly when eccentric loading is a design consideration.

Abstract: Sleep apnea (SA) is a typical rest problem which could disable the mortal physiological frame. Hence, early determination ofSA is of extraordinary interest. The conventional fashion for diagnosing SA is a short- termpolysomnography (PSG) assessment. At the point when PSG has confined availability, programmed SA webbing with a lower number of signs ought tobe allowed of. The main part of this study is to produce and assess a SA position model in view of electrocardiogram (ECG) and blood oxygen absorption (SpO2). We embraced a multimodalway to deal with immingle ECG and SpO2 signalsat the include position. also, highlight determination was led exercising the recursive element disposal with cross-approval (RFECV) computation and random forest (RF) classifier used to insulate between apnea and typical occasions. Tests were led on the Apnea- ECG information base. The presented computation got aperfection of 97.5, a responsiveness of 95.9, an explicitness of 98.4 and an AUC of in per-section grouping, and beat once workshop. The issues showed that ECG also, SpO2 are complementary infeting SA, and that the mix of ECG and SpO2 improves the capacity to dissect SA. Accordingly, the proposed fashion can conceivably be an optionto traditional discovery strategies.
ASSÉDIO SEXUAL NO TRABALHO: Um estudo documental dos principais órgãos governamentais federais brasileiros sobre a temática

Published: November 2023

In adult life, we can cite the sexual division of labor as one of the ways of traditionally separating the male and female place. In organizational spaces, there is the normative attribution of productive work to men and reproductive work to women, the former being accompanied not only by greater social prestige, but also by higher remuneration. This phenomenon appears strongly in the literature as one of the possible justifications for the existence of work environments hostile to the female presence, using discrimination, moral and sexual harassment, as ways of demonstrating that they are not welcome in those spaces or that their value is estimated to be lower than that of men. Considering that sexual harassment is a psychosocial risk factor for workers' mental health and that it especially affects women, resulting in absence from work and, sometimes, their exit from the labor market, the objective of this study was to carry out a documentary research in the main Brazilian federal government agencies, in order to find and classify the official documents released under the theme "sexual harassment at work", between the years 2010 and 2021. based on the Content Analysis technique. It was found that, in most publications on the subject, the responsibilities of the employing organization, as well as the harasser, become secondary; Emphasis is given to victims who “did not do their part” by failing to report, which can contribute to their blame, stigmatization and illness.

Authors: Matiscsak Matus , Trebuna Peter , Duda Richard
Published: November 2023

The aim of this paper is to optimize the production process of graphics card assembly in an unnamed company. For the optimization of the production process, we will use the Tecnomatix Plant Simulation software from Siemens. The first and most important step to optimize the manufacturing process is to analyse the current process so that we can pinpoint where bottlenecks or downtime is occurring. For this reason, the first simulation is dedicated to the current production process. In the second simulation, we have successfully implemented all the proposed changes within the upgraded manufacturing process. These changes included replacing the human workforce with two robots in the tenth stage, which involves the assembly of large components. The implementation of the upgraded process allows 44 graphics cards to be assembled in one hour, an increase of 15 graphics cards compared to the current process. In an eight-hour shift, 353 graphics cards can be assembled, which is 118 graphics cards more than the current production process.

Published: November 2023

In the context of research and development, it is key to achieve accurate and reliable results. However, often to obtain these results, a large number of experiments must be performed, which can significantly extend the research time and increase computational requirements. The solution to these problems may be efficient experimental planning, which allows for a reduction in the number of trials and optimization of the process. This article provides an insight into Central Composite Design (CCD) and its use in simulation experiments. We introduce various types of CCD designs, such as CCC (Central Composite Circumscribed), CCF (Central Composite Face centered), and CCI (Central Composite Inscribed), and analyze their use in creating second-order regression models. We also discuss the specific advantages and disadvantages of these approaches, as well as their possible alternatives, such as the Draper-Lin CCD design.

Authors: Rincón Díaz Jonnathan Abdul
Published: November 2023

La tecnología puede emplearse de manera pedagógica para el fomento de habilidades investigativas y pensamiento crítico en estudiantes universitarios cuando se trata de reflexionar sobre las causas y efectos que acarrean el Antropoceno y el cambio climático. El presente artículo presenta una reflexión sobre una estrategia que se implementó durante el II semestre del 2021 con veintisiete (27) estudiantes de la cátedra San Alberto Magno: Ciencia, Tecnología y Bioética, inscritos en el programa de Ingeniería de Sistemas de la Universidad Santo Tomas, seccional Tunja. En primer lugar, se mencionan algunas definiciones sobre Antropoceno y cambio climático, contextualizando al lector sobre los impactos y consecuencias en regiones de América del Sur y América Central; en segundo lugar, se exponen varios argumentos acerca de cómo ciertas aplicaciones tecnológicas se pueden convertir en mediaciones pedagógicas que permiten al estudiante acercarse a la investigación desde la perspectiva del pragmatismo. Como conclusión, diversas aplicaciones tecnológicas, como Google Earth, acompañada de cuestionamientos, interrogantes y preguntas, favorecen la curiosidad, interés y perplejidad de los estudiantes, acercándolos a la ciencia. Estas aplicaciones simultáneamente contribuyen al razonamiento crítico-reflexivo ante estos fenómenos que amenazan y ponen en riesgo la vida a escala planetaria.
Los supuestos de un deber ético en el Antropoceno: aportes desde el pensamiento decolonial latinoamericano
Authors: Díaz Guzmán Omar David , Moreno Ortiz Juan Carlos
Published: November 2023

El encuentro con el nuevo mundo es un punto de partida importante para pensar las bases culturales del Antropoceno. Desde este punto de vista, el debate fundamental debe partir por resituar la modernidad y con ello darle una cartografía diferente a la forma como se han manifestado determinadas ideas y valores que fueron el fuego que avivó la acción de la crisis ambiental. Dentro de este debate, exponemos algunas diferencias con los puntos de vista de Arias Maldonado, especialmente en relación con el lugar de enunciación de sus planteamientos. Dentro de las múltiples aristas que se derivan de la discusión, el texto se detiene en algunos comentarios sobre el ego cartesiano, pilar fundamental de la modernidad desde la perspectiva decolonial planteada por Dussel, para quien la colonialidad es constitutiva de la modernidad y no derivativa. Desde este punto de vista, este artículo sugiere que el problema fundamental que abonó el terreno para el Antropoceno es la modernidad en su sentido colonial, y se propone que fuera más adecuado hablar de modernoantropoceno o antropomodernoceno europeo, que del concepto universalista de Antropoceno.
Unemployment in the WAEMU Countries: A Cross-Sectional Data Approach
Authors: Niaré Mohamed , Mariko Ousmane
Published: November 2023

The aim of this article is to conduct an empirical evaluation of the microeconomic determinants of unemployment in the West African Economic and Monetary Union (WAEMU), controlling for inactivity. A multinomial logistic analysis has been conducted by using the Harmonized Survey of Household Living Conditions (2019) survey. Our results show that being female, single, young, disabled, and living in urban increases the risk of unemployment and inactivity. Furthermore, despite a higher incidence of unemployment among educated individuals, they are less likely to be inactive compared to those with no education. We also note that women with a university education are less affected by inactivity than men with the same level of education but remain more exposed to unemployment. In addition, age has a very limited influence on unemployment among men, unlike women, where it has a very significant amplifying effect. In addition, the negative effect of university education on unemployment is more pronounced in rural areas than in big cities. Finally, disability does not determine rural unemployment, unlike in urban areas, where it exacerbates it.
Underutilisation of Labour: Underemployment and Skills-Mismatch in Turkey
Authors: Özdemir Caner , Başak Zeynep
Published: November 2023

This paper aims to reveal the extent and characteristics of under and inadequate forms of employment in Turkey. Our descriptive analysis using the Household Labour Force Surveys of 2014-2021 shows that despite not being unemployed, many people do not work in their full capacity or cannot enter the workforce, although they are willing to do so. In addition, the size of these groups varies due to age, sex and education level. To better understand the demographic and socioeconomic determinants of skill-related underemployment, the incidence and evolution of education-occupation mismatch are investigated using the Income and Living Conditions Survey (SILC) of 2016-2021. The results of the multinomial logit models using SILC-2021 indicate that age and education effects are similar for both sexes, but marital status, number of kids and household size have diverging effects for men and women. Moreover, the effects of household income, excluding the respondents’ income, social transfers and social security registration in the household confirm the reservation income hypothesis.

The extant literature defines the young individuals engaged in neither employment nor education or training program as “NEET”. This study investigates the relationship between being NEET and the probability of having mental health disorders among youth in Turkey. We conducted a bivariate probit model with selection by utilizing data from the Turkish Health Surveys (THS) of 2014, 2016, and 2019. The results indicate that the probability of being NEET increases with age, being women and married. In addition, the parents' education and wealth statutes are found to be important determinants of a young individual’s NEET status. The value of the correlation coefficient (1.69) in the probit model indicates that there is a positive association between being NEET and experiencing mental health disorders and that some unobserved factors (i.e., access to mental health services, psychosocial support, cultural factors) are positively related to experiencing mental health disorders. We conclude that the circumstances causing young people to be unemployed also tend to make them have mental health disorders, but unemployed NEET with higher levels of education are less likely to experience mental health disorders.

Published: November 2023

This paper covers aspects of establishing a relationship between the highestorder rotation-invariant moments of inertia and the order of symmetry of Platonic polyhedra. Moments of inertia about arbitrary, but centroidal axes are considered. After an introductory part which summarizes the possible applications of higher-order moments of area and inertia, the revision of the already solved two-dimensional version of this problem is presented, in other words the highest-order rotation-invariant moments of area about the origin of regular m-gons are studied. As a continuation, some aspects of the possible decomposition of spatial finite rotations into a sequence of rotations about given axes will be covered which are of great importance by the extension of the twodimensional problem into three dimensions. Finally, the solution of the 3D problem will be presented, emphasizing the differences between the behavior of the even- and oddorder moments which is present in the 2D case, too, and also between the behaviour of the invariant moments of the tetrahedral and the octahedral or icosahedral solids. As a last part, possible applications will be presented.

Due to increased activities in civil engineering, and especially in the transport infrastructure, and thus an increase in the use of additional construction materials, innovative solutions are needed in finding alternative materials for the preservation of natural resources. One of the solutions for preserving natural building materials is the application of recycled material, which will also meet the required standards in civil engineering. In the transport infrastructure, there is a great opportunity for the use of recycled material, starting from the subbase, through the embankment and all the way to the superstructure and the concrete structures. One of the recycled materials that can be used in construction is fly ash. Fly ash is the most promising waste material when it comes to the wide range of applications in construction. Fly ash is obtained by burning coal in thermal power plants to produce electricity. Due to variations in the composition and characteristics of fly ash, several divisions and classifications have been created. One of the main classifications is according to the American standard ASTM C 618-05 where it is divided into class C and class F fly ash. This research aims to investigate the application of fly ash for subgrade stabilization and to determine the difference from a financial and environmental perspective for the application of fly ash compared to natural stone aggregate. The main research was carried out in connection with the increased use of natural stone aggregate, which appeared as a need during the rehabilitation of state road R1206, section Karpalak - Zelino. Apart from the use of large quantities of stone aggregate for the stabilization of the subgrade, it also had an impact on the financial framework for the realization of the road project. In Macedonia, an analysis of the chemical composition of 4 samples of fly ash obtained in REC Bitola was carried out. From the obtained results, it can be concluded that it belongs to the classification of F-class fly ash and with the use of an activator (lime or cement) it can be used in the stabilization of the subgrade.
Effects of glucose on the cellular respiration in fission yeast expressing human GSK3B gene

Glycogen synthase kinase 3β (GSK3B) acts as a signalling and metabolic enzyme and plays a variety of roles in cellular processes such as cell proliferation, DNA repair, cell cycle, signaling, and metabolic processes. GSK3B has been implicated in numerous diseases, including inflammation, neurodegenerative disease, diabetes, and cancer. Yeasts are suitable models for the investigation of various cellular processes because they include homologous genes to human genes. In this study, we transferred the human GSK3B gene to Schizosac-charomyces pombe (Lindner) cells (gsk3Δ) which include a deletion for this gene. Cells with gsk3 gene deletion and transformant cells with the human GSK3B gene that was reversed by genetic complementation were comparatively examined at the level of gene expression for changes in cellular respiration under varying glucose concentration conditions. For this purpose, the expression of fbp1, pka1 and gsk3 genes were analyzed in cells grown under conditions with different glucose concentrations. We revealed that the GSK3B gene was expressed more in glucose starvation conditions than in other conditions. We also observed a decrease in the level of gene expression in mitochondrial respiration when the human GSK3B gene was transferred in cells that preferred mitochondrial respiration in the absence of the gsk3 gene, regardless of ambient conditions.
La orquesta participativa: estrategia socioeducativa aplicada a los internos de la cárcel de Albolote/España
Authors: Mora Aragón K.
Published: November 2023

Los tratos inhumanos propinados a los reclusos condujeron a las Naciones Unidas a establecer un marco legal para la protección de sus derechos humanos. Este convenio enfatiza que el periodo de privación de libertad debe ser aprovechado por los internos (término que incluye a los dos géneros) en los centros penitenciarios como espacios demandantes de intervenciones dirigidas al desarrollo de su población. En tal sentido, la orquesta participativa fue propuesta como una estrategia socioeducativa a través de la ejecución colectiva de la música, apoyada metodológicamente en la práctica orquestal. En concreto, la investigación tuvo como objetivo analizar la intervención de la orquesta participativa como estrategia socioeducativa en la cárcel de Albolote (España) durante los meses de septiembre y noviembre de 2022. El estudio fue de campo, cuantitativo y descriptivo. Se elaboró un cuestionario ad hoc en función del objetivo. La población se seleccionó al azar de un universo voluntario y de forma intencional, y se tomaron en cuenta personas con conocimientos musicales y sin ellos. Participaron de manera directa 18 internos y de manera indirecta 200, cuyas edades oscilaron entre los 18 y 55 años. Los datos analizados mostraron incidencia del 88 % en su estado de ánimo, el 78 % reportó mayor comunicación con sus compañeros, el 67 % experimentó un aumento de confianza y el 67 % se manifestó en torno a los logros alcanzados. En conclusión, el uso de diferentes instrumentos musicales confiere a los internos un rol que permite el reconocimiento individual y colectivo, lo que favorece la convivencia.
