Prevalence and associated factors of birth trauma in Ethiopia: A systematic review and meta-analysis
Authors: Lera Temesgen , Abebe Amene , Wolka Eskinder , Aydiko Esayas
Published: December 2023

Birth trauma is described as organ or tissue damage caused by physical pressure during birth. Birth trauma ranges from minor problems that go away on their own to significant wounds that might result in infant morbidity and mortality over the long term. It is one of the critical issues that have received the least attention globally. In Ethiopia, evidence regarding the pooled prevalence of birth trauma among neonates is scarce. Therefore, this study estimated the pooled prevalence of birth trauma and associated factors in Ethiopia over the last decade. The Preferred Items for Systematic Reviews and Meta-analysis (PRISMA-2009) guidelines were followed. The PubMed, Scopus, Web of Science, Google Scholar and Google databases were searched. Articles published in the English language in the last decade were included. Data were extracted by a pre-prepared Excel sheet, and analysis was conducted using STATA version 14. Subgroup analysis was also undertaken to evaluate how the prevalence of birth trauma differs across regions of Ethiopia. The pooled prevalence of birth trauma in Ethiopia was 10.57% (95% CI: 3.08, 18.07), with a heterogeneity index (I2) of 92.6% (p < 0.001). Presentation other than vertex AOR 11.94 (95% CI: 6.25–17.62), P = 0.001 and I2 = 53%, labor assisted by forceps AOR 6.25 (95% CI: 2.95–10.10), P = 0.002 with I2 = 51.8% and labor assisted with vacuum AOR 17.47 (95% CI: 4.25–39.46), P = 0.0001 with I2 = 92.9% were factors associated with the pooled prevalence of birth trauma in Ethiopia. The pooled prevalence of birth trauma in Ethiopia is considerable. Non-vertex presentation, use of instrumental delivery and prolonged labor were factors significantly associated with birth trauma. Strengthening neonatal improvement activities (thermal protection, hygienic umbilical cord and skin care, early and exclusive breastfeeding, assessment for signs of serious health problems or need for additional care and preventive treatment), is need.

Published: December 2023

Introduction

During the coronavirus disease 2019 (COVID-19) pandemic, the use of virtual consultations has accelerated to ensure continued access to healthcare despite lockdowns and physical distancing measures. We aimed to determine the knowledge (awareness) of, attitude (acceptability) to, and practice (exposure) [KAP] of virtual consultations (VC), the demographic factors associated with poor KAP, and the correlation between the three KAP domains.

Methods

A cross-sectional study, using a convenience sampling technique, was conducted from 13 September, 2021 to 28 November, 2021. We designed a 45-item VC KAP questionnaire. This was distributed to outpatient users attending cardiovascular, dermatology, geriatrics, haematology, endocrine, respiratory, gastroenterology, rheumatology, or neurology clinics at the University Malaya Medical Centre. It was completed during face-to-face, online, or telephone interviews. The data were analysed using SPSS version 24.0. Binary logistic regression was used to determine the demographic factors associated with KAP. Correlation between KAP domains was determined using Spearman’s rho (r). A p-value of <0.05 was considered statistically significant.

Results

A total of 366 questionnaires were completed. Knowledge (awareness), attitude (acceptability), and practice (exposure) were considered good in 69.7%, 80.9%, and 24.6% of participants, respectively. There were no significant relationships between age, gender, ethnicity, and duration of hospital attendance (years) with knowledge (awareness), attitude (acceptability), and practice (exposure). A moderate positive correlation was seen between knowledge (awareness) and attitude (acceptability) (Attitude total [Atotal]) (r = 0.48, p<0.001), with no significant correlation between knowledge (awareness) and practice (exposure) (r = 0.04, p = 0.45), and attitude (acceptability) (Atotal) and practice (r = 0.01, p = 0.82).

Conclusion

Overall, outpatient clinic users had good knowledge (awareness) of and were receptive towards VC but had poor practice (exposure). More opportunities for VC use in healthcare can increase exposure and subsequent utilisation. Interventions to increase the effectiveness of VC use should be explored in future studies.
Association between dietary omega-3 intake and coronary heart disease among American adults: The NHANES, 1999–2018
Authors: Zhao Mengjie , Xiao Mengli , Tan Qin , Ji Jinjin , Lu Fang
Published: December 2023

Background

Omega-3 has been extensively studied for its cardiovascular disease (CVD) benefits. However, the results of this evidence are inconsistent. Therefore, in this study, dietary omega-3 intake was investigated further in relation to coronary heart disease (CHD) risk among U.S. adults.

Methods

We used data from the National Health and Nutrition Examination Survey (NHANES) database for people ages 20 years and older between 1999 and 2018 to conduct a cross-sectional survey. The Medical Condition Questionnaire (MCQ) was used to determine CHD status. We measured dietary omega-3 intake using two 24-hour dietary recall interviews. Multivariate logistic regression and subgroup analysis were used to explore the correlation between dietary omega-3 intake and CHD. The dose-response relationship between the two was analyzed with a restricted cubic spline (RCS).

Results

31,184 study subjects were included, of whom 1,604 (5.14%) were patients with CHD. By quintile (Q) of dietary omega-3 intake, after adjusting for all confounding factors, compared with Q1, when total dietary omega-3, alpha-linolenic acid (ALA), docosapentaenoic acid (DPA), eicosatetraenoic acid (ETA), eicosapentaenoic acid (EPA), and docosahexenoic acid (DHA) intake reached Q5, the odds ratio (95% confidence interval, CI) of CHD were 0.76 (0.60, 0.96), 0.73 (0.57, 0.94), 0.70 (0.54, 0.92), 0.66 (0.50, 0.85), 0.84 (0.69, 1.02), and 0.83 (0.64, 1.07), respectively, while EPA and DHA were not significantly associated with the disease (Trend p > 0.05). Intake of omega-3 and CHD were linearly related (P for nonlinear = 0.603). No significant interactions were found within subgroups except for the age group (P for interaction = 0.001). Sensitivity analysis and multivariate logistic regression results are generally in agreement.

Conclusions

Total dietary omega-3, ALA, DPA, and ETA intake were negatively associated with CHD risk. In contrast, EPA and DHA had no significant correlation with CHD.
How does perceptions of social justice affect farmers’ political participation?—Evidence from China
Authors: He Zijian
Published: December 2023

Ronald Inglehart’s postmaterialist theory suggests that with the advancement of industrialization and economic prosperity, there will be a significant transformation in people’s societal values. Concurrently, their forms of political participation shift from conventional activities to unconventional politic activities. However, most research on this topic has been predominantly focused on Western countries. In fact, rural farmers in China serve as an excellent experimental group for testing this theory since they have experienced rapid economic growth while still being deeply influenced by traditional authoritarianism culture.Using a sample of 6,689 respondents from the 2019 Chinese Social Survey (CSS) and employing a Binary Logistic Regression Model, we discovered that Chinese farmers’ perception of overall societal justice exhibits a U-shaped relationship with various forms of political participation. Specifically, it shows a significant negative correlation with non-institutional political participation, such as contact-officer participation, but a significant positive correlation with institutional political participation types like community participation and election participation.Our further research indicates that the three subtypes of perception of societal justice are significantly negatively correlated only with non-institutional political participation, while their statistical relationship with institutional political participation is not significant. We believe that the underlying reason for this phenomenon lies in the unique interpretation of societal justice within Chinese traditional culture. Additionally, through a comparative analysis of models on political participation behavior and willingness, we found that despite significant inequalities and disparities in institutional structures and levels of economic development between rural and urban areas in China, rational considerations of the risks and costs associated with defying the government deter Chinese farmers from engaging in non-institutional politic activities unless their emotional resentment towards unjust practices reaches a certain threshold.
Sanitation services for the urban poor: A social capital approach to sanitation challenges in informal settlements
Authors: Chumo Ivy , Mberu Blessing , Wainaina Cynthia , Murigi Wanjiru , Sumba Leunita , Kabaria Caroline
Published: December 2023

Poorly managed sanitation is degrading, unhealthy and far too dominant among the urban poor. The conventional solution to poorly managed onsite sanitation and/or open defecation is for governments to provide adequate sanitation at subsidized prices. Few governments in low and middle income countries can subsidize access to sanitation facilities for people living and working in informal settlements. This leaves the urban poor in informal settlements to face challenges in accessing safely managed sanitation, with some residents and manual pit emptiers adopting social capital approaches. We sought to identify sanitation challenges along the value chain and social capital approaches to addressing the challenges. We used qualitative approaches. Our target population were manual pit emptiers and community members. We analysed data using conventional content analysis methodology. We grouped sanitation challenges into those that are outside individual households and those that are at the individual household. Challenges outside the household could not be controlled at the individual level, and included legislative, physical, and social challenges, while challenges at the individual household could be controlled at individual level, and included health, financial and technical challenges. As a result of these challenges, both the manual emptiers and community members adopted social capital approaches, which included the use of reciprocity and trust, networks and information channels and norms to counter the challenges. Sanitation challenges along the sanitation value chain should persuade policymakers and practitioners that sanitation extends beyond the four walls of a sanitation containment facility, to include emptying, transportation, treatment and disposal. Many of the challenges could be attributed to governance outside the sanitation sector. Hence long-term improvement of sanitation conditions in informal settlements ought to be supported by broader policies and strategies like social capital that begins by thinking outside “the sanitation box”.

Sites of Cultural Production in Response to Mass Extinction
Authors: Turner Stephanie , Lindahl EvaMarie , Nicholson Tara
Published: December 2023

This conversation, mediated by Tara Nicholson, considers Stephanie Turner and EvaMarie Lindahl’s research in cultural representations of extinction and investigations of more-than-human forms of storytelling through an art historical lens. In response to Lori Gruen’s classification, extinction is a distinctive loss of ‘animal cultures’. It is more than biodiversity destruction or a static inventory of a species’ death. Nonhuman ways of building bonds, reproducing, teaching offspring, constructing homes and mourning the dead, are all systems of knowledge lost in extinction (Gruen et al. 2017). This conversation offers compassionate ways of bearing witness to species destruction and a space for empathy and kinship. The authors ask, how can dialogue between science and art lead to new understandings of the ‘wicked problem’ of mass extinction during climate crisis? Examining methodologies of cross-disciplinary storytelling and cultural production, this exchange connects museum practice, large-scale public artworks and artistic research as types of embodied knowledge to promote public awareness surrounding the acceleration of species extinction.

The Common Law of Landscape Hostility in the Lives and Deaths of Honeybees
Authors: Goltz Caleb
Published: December 2023

This article offers a legal explanation for the decline of honeybees. While most investigations into bee populations and bee survival rates have been scientific, this article provides an additional set of causes, showing how our legal definitions of property and standards of negligence contribute to a landscape hostile to the lives of bees. Examining recent litigation in the United States and Canada, it shows how legal concepts of property impact the lives of bees, especially in cases of pesticide overspray near property boundaries, and in the forms of knowledge and ignorance in play in contesting duties of care in negligence cases. By expanding our understanding of the causes of bee death, this article points toward additional ways in which the stressors that bees face might be reduced.
No Going Back: Un-Fixing the Future of De-Extinction
Authors: Beier Jessie
Published: December 2023

Extinction is a colossal problem facing the world’ proclaims the Colossal Laboratories & Biosciences website, adding, ‘And Colossal is the company that’s going to fix it’. For Colossal, this involves combining the science of genetics with ‘the business of discovery’ in order to bring back the woolly mammoth, which will not only help ‘rewild’ lost habitats, but also contribute toward ‘making humanity more human’. De-extinction is the process through which extinct species can be brought back into existence, often with the goal of reintroducing species to the wild and restoring ecosystems. While still in its nascent state, the science of de-extinction is currently expanding and advancing through, for instance, projects like Colossal’s, raising numerous ethical, social and technological debates about what defines a species, and thus its regeneration; how such definitions shape conservation paradigms; and, ultimately, what we mean when we talk about life, death and species extinction. With their commitment to ‘reversing climate change’ while also ‘advanc[ing] the economies of biology and healing through genetics’, Colossal’s work has not only been deemed ‘game-changing’ in terms of “saving” endangered species, but also in terms of ‘future proofing’ the environment by reshaping how the world thinks about the power of genetics for solving pressing challenges in the life sciences today, including the challenge of extinction. In this de-extinction example, then, the problem of extinction is actualized in relation to solutions aimed at enacting further control over the planet, this time by ‘rewinding’ and ‘reversing’ ecological destruction, so as to fix the human-caused disaster, and in so doing, fix the future. In this essay, I trace the line between ‘the business of discovery’ and ‘making humanity more human’ in order to draw out what I see as some of the broader refrains and fixations that have come to infect future-oriented ecological discourse in these times of dying. Looking to the example of Colossal, I examine the ways in which extinction, and the corollary project of de-extinction, has become at once a territorializing force that works to re-install monohumanist fantasies of planetary control, and a potentially deterritorializing force for letting go and giving up.
Rhetorics of Species Revivalism and Biotechnology – A Roundtable Dialogue
Authors: Kasprzycka Eva , Wrigley Charlotte , Searle Adam , Twine Richard
Published: December 2023

This informal dialogue contextualises and explores contemporary practices of nonhuman animal gene-modification in de-extinction projects. Looking at recent developments in biotechnology’s role in de-extinction sciences and industries, these interdisciplinary scholars scrutinise the neoliberal impetus driving ‘species revivalism’ in the wake of the Capitalocene. Critical examinations of species integrity, cryo-preservation, techno-optimism, rewilding initiatives and projects aimed at restoring extinct animals such as the woolly mammoth and bucardo are used to map some of the necessary restructuring of conservation policies and enterprises that could secure viably sustainable – and just – futures for nonhuman animals at risk of extinction. The authors question what alternatives are being ignored in the wake of technoscientific responses to the climate emergency, and interpret the motivations, tactics and tools responsible for commodifying nonhuman animals down to the cellular level. Our conversation on the messy relations within endangered ecologies offers alternative approaches to environmental governance and strategies for addressing the climate and biodiversity crises today.

Dense ceramic materials were obtained at firing temperatures of 800 – 1150 °C, and porous materials at temperatures 1200 – 1280 °C. The physical, mechanical and technical characteristics of the obtained ceramic materials were studied. Porous ceramics, sintered at 1280 °C, belongs to the class of heat-insulating materials with increased thermal conductivity.
The potential of Lamiaceae essential oils against respiratory tract diseases – a mini-review
Authors: Jyotirmayee Lenka , Khuntia Snehalata , Panda Nikita , Basudeba Kar , Suprava Sahoo
Published: December 2023

Respiratory tract infections (RTIs) are common infections in the global population, particularly among children. Due to the rise of antibiotic resistance, multidrug-resistant bacteria, and the numerous adverse effects of synthetic drugs, there is a constant demand for new and safe alternative treatments. Natural plant-based alternatives have become more popular, while chemical drugs have been questioned for their safety and side effects. One of the most promising solutions to the global issue of respiratory tract infections is the exploration of the antiviral and antibacterial properties of essential oils (EOs). Because of their volatility, EOs can be inhaled, allowing them to reach both the upper and lower respiratory tracts. Additionally, their antimicrobial and anti-inflammatory properties along with their phytochemical composition make them more effective for treating respiratory tract infections. Humans are less likely to be affected by EOs because of their low toxicity and less risk of resistance to pathogenic organisms. Lamiaceae (also called Labiatae) is one of the most important herbal families, and it incorporates a wide range of plants like thyme, holy basil, rosemary, basil, etc. with potential therapeutic properties. The pharmacological properties of Lamiaceae are mainly due to its EOs, which have various activities like anti-tumor, anti-diabetic, insecticidal, neuroprotective, anti-asthmatic, and others. Overall, the main objective of this review is to provide an overview of the general characteristics of certain EOs from the Lamiaceae family about their ability to alleviate the signs and symptoms of respiratory diseases, including respiratory tract infections.
Parts-of-Speech (PoS) Analysis and Classification of Various Text Genres
Authors: Mendhakar Akshay , H S Darshan
Published: December 2023

Natural language processing (NLP) has made significant leaps over the past two decades due to the advancements in machine learning algorithms. Text classification is pivotal today due to a wide range of digital documents. Multiple feature classes have been proposed for classification by numerous researchers. Genre classification tasks form the basis for advanced techniques such as native language identification, readability assessment, author identification etc. These tasks are based on the linguistic composition and complexity of the text. Rather than extracting hundreds of variables, a simple premise of text classification using only the text feature of parts-of-speech (PoS) is presented here. A new dataset gathered from Project Gutenberg is highlighted in this study. PoS analysis of each text in the created dataset was carried out. Further grouping of these texts into fictional and non-fictional texts was carried out to measure their classification accuracy using the artificial neural networks (ANN) classifier. The results indicate an overall classification accuracy of 98 and 35 % for the genre and sub-genre classification, respectively. The results of the present study highlight the importance of PoS not only as an important feature for text processing but also as a sole text feature classifier for text classification.
Hypothetical mistakes: hedging wrong answers with conditional language in initiation-response-evaluation (IRE) sequences in an American high school classroom
Authors: Chandras Jessica Sujata
Published: December 2023

This article analyzes American high school students hedging incorrect responses to teacher-initiated questions in IRE (Initiation-Response-Evaluation) format using conditional language and hypotheticals in ways that facilitate an affiliative stance between students and their teacher. Scholarship on hedging details its use to approximate responses as a shield against doubt and criticism or as collaborative communication, whereas stance is a grammatically encompassed expression of attitudes related to the content of a message. This study brings together theories of stance, hedging, and conditional language use to outline how errors can be a student-initiated pedagogical tool to deepen explanations and engagement. To broaden understanding of the form and function of both incorrect answers and hedging as a structure expanding traditional IRE turntaking for managing classroom discourse, this article outlines seven examples total where students hedge what they know to be incorrect answers drawn from recordings made in forty, fifty-minute high school level Latin lessons over the 2019–2020 academic year. This study presents a model and impacts of students creatively reconfiguring evaluative responses along with their teacher during instruction through hedging incorrect information in conditional, and sometimes hypothetical, formats.

Published: December 2023

This article presents a compact implantable antenna for biomedical use in the ISM band (2.4–2.48 GHz). The antenna is designed with Roger RT/duroid 6010.2LM high permittivity substrate of thickness 0.25 mm, and feed with a 50 Ω co-axial feed. A hybrid-loop resonator slot structure and C & I-shaped slots in the radiating patch has enabled the antenna to work in the ISM band. Via less ground makes this design simple, easier to fabricate, and a suitable candidate for implantable application. The proposed antenna occupies a small volume of 0.0984 λ
0 × 0.082 λ
0 × 0.00468 λ
0 and retained 152 MHz bandwidth (2.4077–2.5599 GHz with FBW 7.64 %) with a maximum gain of −22 dBi where λ
0 is guided wavelength. The projected antenna has good performance in the multi-layer tissue model, male human head voxel model, frequency-dependent skin model, and in muscle phantom by maintaining a minimum −20 dB return-loss in the ISM band. The proposed antenna’s Device Integration using a frequency-dependent skin phantom was performed and the results are well-suited for biomedical applications in the ISM band. The bare antenna was used to study the Specific Absorption Rate (SAR) in the human scalp. Where for 1 g and 10 g tissues the investigated results are 626.05 W/kg and 84.4 W/kg for an input power of 1 W, however the input power is limited to maximum 2.55 mW (for 1 g tissue) and 23.56 mW (for 10 g tissue) to comply with IEEE SAR guidelines. The qualities of the manufactured antenna are verified in a skin-imitating gel and animal tissue that exhibits good agreement with the simulation outcomes.

Authors: Herculano Miguel C. , Jacob Punnoose
Published: December 2023

We construct a Financial Conditions Index (FCI) for the United States using a dataset that features many missing observations. The novel combination of probabilistic principal component techniques and a Bayesian factor-augmented VAR model resolves the challenges posed by data points being unavailable within a high-frequency dataset. Even with up to 62 % of the data missing, the new approach yields a less noisy FCI that tracks the movement of 22 underlying financial variables more accurately both in-sample and out-of-sample.
Convection Initiation Forecasting Using Synthetic Satellite Imagery from the Warn-on-Forecast System
Authors: Jones Thomas A. , Mecikalski John R.
Published: December 2023

Forecasting convection initiation (CI) has advanced greatly during the past decade through the use of high-resolution satellite observations and model output. One of the primary CI products used in forecast operations is based on GOES-16 visible and infrared imagery along with GLM lightning flash detections to determine the location of growing ice-containing cumulus clouds that are the precursor to developing thunderstorms.
Another approach to CI forecasting that has recently become available is high frequency output from numerical weather prediction (NWP) models such as the Warn-on-Forecast System (WoFS). NWP model simulated composite reflectivity forecasts are one method used to determine when and where severe thunderstorms might develop. However, waiting for high reflectivity (> 40 dBZ) to be created within the NWP model limits the potential lead time available to forecasters when using WoFS output to anticipate areas where convection might form.Also, forecast reflectivity alone does not always give an indication of whether or not the precipitation developed by the NWP model is convective in nature. To address these limitations, this work applies a CI forecasting methodology developed for GOES satellite data on synthetic satellite imagery produced from WoFS output. Forecast cloud objects are tracked over a 10-min interval and CI forecasting parameters are applied to determine whether or not these cloud objects will continue to develop into organized thunderstorms.
Dentate Gyrus Granule Cells Show Stability of BDNF Protein Expression in Mossy Fiber Axons with Age, and Resistance to Alzheimer’s Disease Neuropathology in a Mouse Model
Authors: Criscuolo Chiara , Chartampila Elissavet , Ginsberg Stephen D. , Scharfman Helen E.
Published: December 2023

Brain-derived neurotrophic factor (BDNF) is important in the development and maintenance of neurons and their plasticity. Hippocampal BDNF has been implicated in Alzheimer’s disease (AD) because hippocampal levels in AD patients and AD animal models are often downregulated, suggesting that reduced BDNF contributes to AD. However, the location where hippocampal BDNF protein is most highly expressed, the mossy fiber (MF) axons of dentate gyrus granule cells (GCs), has been understudied, and not in controlled conditions. Therefore, we evaluated MF BDNF protein in the Tg2576 mouse model of AD. Tg2576 and wild-type (WT) mice of both sexes were examined at 2–3 months of age, when amyloid-β (Aβ)is present in neurons but plaques are absent, and 11–20 months of age, after plaque accumulation. As shown previously, WT mice exhibited high levels of MF BDNF protein. Interestingly, there was no significant decline with age in either the genotype or sex. Notably, MF BDNF protein was correlated with GC ΔFosB, a transcription factor that increases after 1–2 weeks of elevated neuronal activity. We also report the novel finding that Aβ in GCs or the GC layer was minimal even at old ages. The results indicate that MF BDNF is stable in the Tg2576 mouse, and MF BDNF may remain unchanged due to increased GC neuronal activity, since BDNF expression is well known to be activity dependent. The resistance of GCs to long-term Aβ accumulation provides an opportunity to understand how to protect vulnerable neurons from increased Aβ levels and therefore has translational implications.
Verification of artillery fire under the influence of random disturbances for the computer game ARMA 3

Published: December 2023

Computer gaming occupies a firm place in today's media culture and media business. Computer games are widely used both as a means of entertainment and as an educational tool. Military games traditionally hold a place in computer gaming. However, it is in this sector of gaming that a sharp contradiction is observed between the super-realistic quality of the video component and the limited scope of the game's script component. In particular, in the development of military-themed games, the introduction of modern weapon models is rapidly evolving. At the same time, the experience of military conflicts over the last decade and the new tactical techniques developed are difficult to implement in games. This work demonstrates the possibility of improving the artillery component of ARMA 3. In artillery fire, random disturbances are always present. These disturbances cannot be eliminated during the preparation of the firing. In practice, they are compensated by consecutive ranging shots. Modern artillery firing tactics require the maximum reduction of the firing time of the artillery unit. In this regard, methods for verifying each artillery shot are very relevant. Verification is understood as confirming the effectiveness of a shot immediately after it is made. A method for verifying a shot by recording the flight time of a projectile through three control points is proposed and studied. Based on the recorded flight times by sensors, a system of approximating parabolas is constructed. The solution of the system allows determining the expected point of the projectile's burst before it lands. The deviation of the burst point from the aiming point verifies the quality of the artillery shot. Simulation modeling of the proposed method has been conducted. It is demonstrated that parabolic approximation effectively compensates for random disturbances of the shot. A comparison of the proposed method with the method of compensating disturbances through consecutive ranging shots is made. It is shown that the proposed method significantly reduces the firing time of the weapon and the ammunition expenditure for hitting the target for the ARMA 3 player.
Simulation of power consumption control of receivers at underground iron ore mining enterprises

Published: December 2023

The article presents the results of developing a concept for controlling the process of power consumption by electrical receivers with a voltage of up to 1000 V at underground mining enterprises in the function of hourly tariffs, which are characterized by variable pricing for the day ahead in current market conditions. The following parameters are considered: limitations on operation duration of a separate electrical unit during the day, the maximum load on underground substation transformers, and the amount of power ordered by the enterprise, the excess of which leads to the application of penalties. To solve the control problem, it is proposed to apply a heuristic optimization method based on a genetic algorithm. System efficiency is studied by determining settings of the evolutionary search algorithm that would ensure the lowest cost of power purchase. In particular, the crossover function (one-point, two-point, or Laplace) and the number of elite individuals in the population are modified. The experiments are carried out on the basis of the Global Optimization Toolbox in the MATLAB software package. Simulation of system efficiency through different settings of the genetic algorithm demonstrates that the minimum power cost can be ensured by using the Laplace crossover method with 10 individuals in a population of 100, of which 10 are elite and pass to the next generation unchanged. This option allows obtaining an average of 2.62 % lower daily power cost than the other parameters studied. The proposed method of power consumption control allows us to identify the achievable potential for reducing the energy component in the final product cost of iron ore mining at underground mining enterprises. It can be recommended for practical implementation at both operating and projected enterprises
Nadin – Gradina

Published: December 2023

Tijekom 2015. godine, u suradnji Sveučilišta u Zadru i Sveučilišta u Maineu (SAD), započela su sustavna istraživanja Gradine u Nadinu. Pet probnih sondi istraženo je na različitim položajima unutar areala naselja definiranog tzv. megalitskim bedemom da bi se omogućilo razumijevanje dubine depozita, kronološka sekvencija i integritet arheološkog zapisa. Preliminarni rezultati pokazuju složenu kulturnu stratigrafiju koja u pojedinim sondama prelazi 2 m dubine i potvrđuju intenzivan razvoj zajednice koja je obitavala na Gradini u Nadinu tijekom željeznog i rimskog doba. Naselje starijeg željeznog doba još uvijek nije potvrđeno, iako je ono, sudeći po istraženom dijelu pripadajuće nekropole na ravnom, moralo egzistirati. U mlađem željeznom dobu iskorišten je širi prostor koji, čini se, uglavnom odgovara antičkim gabaritima naselja. Najvažnija fizička transformacija naseobinskog tkiva povezuje se s nastupom rimske faze nadinske povijesti kada Nedinum stječe status municipija. Na izmaku kasne antike položaj je napušten da bi ponovno zadobio važnost tijekom kasnog srednjeg, odnosno novog vijeka. Tada se na Gradini gradi utvrda u sustavu obrane Mlečana, a zatim i Osmanlija, čiji ostatci sačuvani do visine od nekoliko metara dominiraju današnjom vizurom lokaliteta.

Published: December 2023

El trabajo analiza el principio de cooperación en una tira de viñetas de Quino, poniendo el foco en las máximas y submáximas conversacionales, así como en los tipos de implicaturas conversacionales y en los casos en que se (in)cumplen. Se investigan los dos planos que se contraponen: uno directo y literal, el de profesora-alumnado, y otro indirecto y adicional, el de adultos-niños, que, a su vez, se replican en el artificio polifónico del doble destinatario/emisor, así como en el del malentendido. Con respecto al componente emocional que se vehiculiza en la tira de viñetas de Quino como elemento reforzante o atenuante del acto de habla, la utilización de la rueda de emociones de Robert Plutchik y Lindsay Braman permite visualizar qué emociones y cuántas actualizan los dos personajes protagonistas y de qué signos físicos se acompañan.
Trabajo, desposesión y sufrimiento en el capitalismo. De la crisis del mundo liberal al neoliberalismo
Authors: Catalina Gallego Cristina
Published: December 2023

Este artículo aborda críticamente la relación entre trabajo y sufrimiento en las sociedades contemporáneas a partir de una reflexión sobre la condición del trabajo en el capitalismo y sus transformaciones históricas desde el mundo liberal hasta la actualidad. Para ello, se parte del análisis de la Crítica de la Economía Política de Marx sobre la coacción impersonal que obliga a la venta de la fuerza de trabajo como único medio de vida a los desposeídos de otros medios de subsistencia. A partir de esta comprensión del antagonismo social que subyace al trabajo en el capitalismo se abordan algunas de las transformaciones históricas que afectan a los rasgos concretos del proletariado, el trabajo asalariado o la sobrepoblación relativa. Con ello se trata de pensar críticamente las distintas modalidades y planos en los que se despliega la relación, históricamente específica, entre trabajo y dominación, trabajo y subjetividad y trabajo y sufrimiento.
¿El cuerpo como frontera? El problema de la limitrofía ontológica humano-animal en L’animal que donc je suis de Derrida
Authors: Firenze Antonino
Published: December 2023

El propósito de este artículo es circunscribir el concepto de limitrofía humano- animal esbozado por Derrida en su obra póstuma L’animal que donc je suis. Para ello, el análisis se focaliza en el problema de la mirada animal en tanto que mirada que lo absolutamente otro puede dirigir al humano, resaltando asimismo la vulnerabilidad como paradigma ontológico de toda corporeidad viviente, tanto animal como humana. De este modo, el artículo pone de relieve los principales elementos conceptuales mediante los cuales Derrida deconstruye radicalmente el estatuto ontológico de la subjetividad humana, a la vez que muestra esta inquietante proximidad ontológica de animal y humano que la noción de limitrofía permite vislumbrar.
María Zambrano en el II Congreso Internacional de Escritores para la Defensa de la Cultura. (A propósito de un artículo mutilado: rescate y edición)
Authors: José Martín Francisco
Published: December 2023

Rescate y edición de un artículo parcialmente olvidado de María Zambrano, concretamente el dedicado al II Congreso Internacional de Escritores para la Defensa de la Cultura (julio 1937), del que se conocía su edición chilena en la revista Ercilla y ahora se descubre que era una edición mutilada con relación a su edición argentina en el diario Crítica de Buenos Aires.
El discurso sobre el revenge porn en la prensa: estudio de caso de Rosalía y sus fotografías manipuladas
Authors: Martínez Sánchez María
Published: December 2023

El porno de venganza (revenge porn) es una práctica que ha visto un auge y un cambio en la forma de ejercerse a partir de la democratización de las herramientas de inteligencia artificial que permiten generar imágenes falsas. En esta investigación se lleva a cabo un análisis crítico del discurso con perspectiva feminista del caso de la difusión de imágenes manipuladas de la artista española Rosalía. En mayo de 2023 el cantante JC Reyes publicó unas imágenes falsas en su cuenta de Instagram y los medios de comunicación se hicieron eco de ello. El objetivo principal es descubrir si la prensa sitúa el caso estudiado como un acto dentro de la práctica del porno de venganza o si lo clasifican como un hecho aislado. En primer lugar, en el artículo se revisan los deep fakes (imágenes falsificadas), los cuales permiten profundizar en el concepto del revenge porn y su implicación con la inteligencia artificial. En segundo lugar, se presenta el caso analizado y la metodología de análisis del discurso; y en tercer lugar la discusión y principales conclusiones de este trabajo. En el análisis discursivo se puede apreciar que no se relaciona prácticamente el caso analizado con el revenge porn ni con las formas de violencia simbólica, la víctima es presentada como un sujeto activo y se afianza la utilización del cuerpo femenino como una estrategia de marketing al generarse contenidos que sitúan al autor de los hechos en el panorama musical.
Ironía, cuerpo y enfermedad en Juan del Valle y Caviedes
Authors: Escobar Tapia Héctor Omar
Published: December 2023

Se analizan dos poemas de Juan del Valle y Caviedes, poeta que desarrolló su actividad en el siglo xvii. Caviedes se caracterizó por el uso de la ironía para criticar las prácticas médicas de su tiempo y por ser el iniciador de la poesía criolla en el Perú. Se han utilizado categorías de semiótica para explicar los mecanismos de la ironía y la importancia del cuerpo en la poesía de Caviedes. La explicación propuesta se divide en dos puntos: en primer lugar, se argumenta que el yo poético utiliza la ironía y la polifonía para criticar las prácticas médicas. Y, en segundo lugar, se remarca la importancia del cuerpo en la poesía de Caviedes. El artículo concluye que el cuerpo es la condición radical de la significación en la poesía de Caviedes.
Arte gráfico, modernidad y cultura visual en la revista ilustrada limeña El Correo del Perú (1871-1878)
Authors: Rodríguez Díaz Diana Elvira Mercedes
Published: December 2023

Hacia el siglo xix se inicia el proceso de masificación de la imagen a través del desarrollo de los nuevos procesos de reproducción técnica. En este marco surgen las revistas ilustradas que se convierten en soporte de la cultura letrada y marcan el auge del arte gráfico. La presente investigación tiene como objetivo demostrar cómo se transforma el sistema de producción artística y se configura el proceso de percepción visual del lector limeño moderno. Asimismo, cómo desde la revista El Correo del Perú se innova en la prensa con la inclusión de imágenes y cómo se elabora una cultura visual que construye un discurso de modernidad y progreso en el Perú decimonónico.
Tecnología y arte: una relación activa
Authors: Carrillo Pastor Giuliana María
Published: December 2023

En el marco de la relación de las artes con otras formas de expresión y de su materialización, el presente trabajo reflexiona en torno a las múltiples y fructíferas relaciones que existen actualmente entre el arte y la tecnología, con el objetivo de reconocer y valorar los modos en que los avances de las ciencias repercuten y benefician un ámbito que a veces suele pensarse como estático y atemporal. Las nuevas estrategias de acercamiento del arte a la sociedad proporcionan nuevas formas de sensibilización y una mayor interacción con el objeto artístico. Asimismo, los últimos avances tecnológicos permiten develar los secretos del arte, así como su conservación, restauración y recreación.

Realization of business rules represented using formal logic sentences in information systems
Authors: Lebedys Evaldas , Vasilecas Olegas
Published: December 2023

The paper deals with the problems of creating business rules model that would be formal enough for automated transformation to Information systems model and realization in program systems. There are many modelling languages and diagrams suitable to model business rules of different classes, but there is no one ideal. Every modeling language used to model business rules has to be formal enough and understandable for business people with no additional knowledge. The choice of modelling language may impact completeness, understandability and the level of formalization. This may also impact the process of transformation of created model to Information systems model. In this work it is proposed to model business rules using formal logic sentences.

Parallel Monte Carlo computations in SCore environment
Authors: Vošterienė Svajonė
Published: December 2023

Parallel Monte Carlo (PMC) methods are successful because particles are typically independent and easily distributed to multiple processors. We use the PC Cluster TAURAS [1] with the SCore cluster system software on top of Linux OS to present the strategy for parallelizing Monte Carlo calculations. The cluster help us to generate parallel random numbers for simulating our task and to computerize parallel programs. In this particle we present the PMC, who let us simulate the mortar firing. We propose compu­tations that are very effective because the digital experiment can substitute costly firings at the shooting range, the pollution of the environment is reduced, etc.

A three-dimensional model of semantic search: queries, resources, and results
Authors:   Institute of Software Systems NAS of Ukraine, Rogushina J.V.
Published: December 2023

We propose three-dimensional model of semantic search that analyzes search requests, information resources (IRs) and search results. This model is proposed as an additional tool for describing and comparing information retrieval systems (IRSs) that use various elements of artificial intelligence and knowledge management for more effective and relevant satisfaction of user information needs. In this work we analyze existing approaches to the semanticization of search queries and the use of external knowledge sources for retrieval process. The values of parameters analyzed by this model are not mutually exclusive, that is, the same IRS can support several search options. More over, the representation means of queries and resources are not always comparable. The model makes it possible to identify IRSs with intersected triads «request-IR-result» and to perform their comparison precisely on these subclasses of search problems. This approach allows to select search algorithms that are more pertinent for specific user tasks and to choose on base of this selection appropriate retrieval services that provide information for further processing. An important feature of the proposed model is that it uses only those IRS characteristics that can be directly evaluated by retrieval users.
