Authors: Cui Qinglin ,   Editorial Office, Nakamura Hiromitsu , Mizui Yoshinobu , Fujiwara Hiroyuki
Published: January 2024

The Nankai Trough Earthquake, which is estimated to have a 70%–80% probability of occurring within the next 30 years, necessitates considering various scenarios due to the extensive seismic source region and call for advancing disaster preparedness measures. Assessing direct damage caused by earthquakes is considered particularly challenging compared to assessing human and physical damage due to its intricate composition. However, the existing research in model analysis aimed at real-time estimation has yielded results, namely, the ability to promptly calculate direct damage from earthquakes using seismic motion and stock quantities as inputs. This study aimed to leverage the research outcomes of real-time estimation to approximate the direct damage costs that would be caused by the Nankai Trough Earthquake. Three hazard assessment cases were selected, based on damage estimations to be attempted. The results indicated that a damage estimation approach based on a common foundation dataset and model analysis considering different occurrence scenarios is more suitable for evaluating results and assessing the importance of mitigation measures than conventional scenario-based damage estimations.
HIERARCHICAL TWO-WAY SENSITIVITY ANALYSIS IN DIVERSE BENEFIT SCENARIO OF MATENGGENG DAM FEASIBILITY
Authors: Roy Andreas F. V. , Yonathan Tan Leonardo
Published: January 2024

The Indonesian government formulated plans for the construction of the Matenggeng Dam, aiming to enhance local agricultural productivity. This dam will store water from the Cijolang River, a tributary of the Citanduy River. The construction of Matenggeng Dam encompasses option of municipal water enhancement and four normal water levels: 190m, 194m, 197m, and 199m. According to the hydrology, social-economic, and dam structure design reports, each option entails distinct benefits and costs. The report informed dam’s agriculture potential benefit, land use, and cost by each water level option. To assess the project's viability, an economic analysis and hierarchical two-way sensitivity analysis has been conducted to examine the impact of water level variations on the economic evaluation outcomes. Results obtained at a discount rate of 10.08% indicate that 194m and 197m water level options exhibit positive NPV, IRR greater than the interest rate, PBP less than 50 years, and a BCR exceeding 1. While both options demonstrate feasibility, the 194m appears more favorable. Despite the 197m water level presenting a slightly higher IRR by 0.02%, respectively, it incurs a cost deviation of IDR 100 billion. However, the 194m water level emerges as a more enticing choice due to its lower cost implications.

An Overview of the Archaeological, Radiocarbonic and Palaeoclimatic Record at the Iberian Peninsula During the Middle to Upper Paleolithic Transition
Authors: Mayya Seba Sultan
Published: January 2024

The Iberian Peninsula is an important region for the study of the transition from the Middle to the Upper Palaeolithic (MUPT). Broadly speaking, this transition refers to the period in which anatomically modern humans (Homo sapiens, AMH) first appear in the archaeological record of Palaeolithic Europe, as well as the subsequent extinction of Neanderthals in Europe. The Iberian Peninsula is an important region for the study of the causes of the replacement of Neanderthals by Anatomically Modern Humans, as it was one of the last places where these Neanderthals lived. Many theories have been proposed to explain the disappearance of Neanderthals. They range from competition with Homo sapiens to environmental factors such as climate change. Here we investigate the link between the displacement of Neanderthals by AMH populations and climate change by providing an overview of the archaeological and climatic record in the Iberian Peninsula during the Middle to Upper Palaeolithic Transition (MUPT). Through the use of a relational database (combining archaeological information and radiocarbon dates), Summed Probability of Calibrated Radiocarbon Dates (SPCD), palaeoenvironmental records, GIS and spatial modelling, this study examines the timing of the dispersal of the last Neanderthals and the occurrence and distribution of AMH and their population fluctuations in Iberian periods of climate change. This research is still under investigation.

Authors: Nataraj Chandrasekharan , G Karthikeyan , G Jaya Bharathi , Duraikannan Shankar
Published: January 2024

Solar energy, a prominent renewable source, has reached an installed capacity of 71.78 GW in India. This research explored the load demands of the computer center at an engineering college in Tanjore, Tamil Nadu, India. The computer center at the engineering college has an annual energy requirement of 260,552 kWh/Year. Consequently, the research focused on the planning and implementation of a standalone photovoltaic (SAPV) system, assessing it against the institution's total annual energy consumption. The performance ratio and losses of the SAPV system with both direct coupling and an MPPT charge controller was compared. This comparative analysis aimed to evaluate the efficacy of two solar photovoltaic control methods—SAPV direct coupling and MPPT (Maximum Power Point Tracking) control—in optimizing energy harvesting from solar panels.

Authors: Hamdan Abel , Sharma Sumit , Baynes Kimberly , Ali Rula A. Hajj , Lowder Careen Y. , Srivas Sunil K.
Published: January 2024

Background / Aims
Anti-tumor necrosis factor (Anti-TNF) agents have proven beneficial for the treatment of chronic non-infectious uveitis, yet rare neurological complications and demyelinating disease can occur with their use. Management of uveitis and neurological disease after developing these rare complications is not well understood. We sought to identify these specific cases and their outcomes through a retrospective observational case series.
Methods
EMR chart review of 394 non-infectious uveitis patients on anti-TNF therapy focused on identifying patients seen by uveitis specialists at a single institution who were on anti-TNF therapy and had developed neurological symptoms. Cases were reviewed for subsequent management and outcomes of both their neurologic and ocular inflammatory disease.
Results
Five (5) patients were included following complaints of neurological symptoms while on anti-TNF therapy. Subsequent demyelinating diagnosis, acute treatment, and long-term course were described. All five patients continue to be inactive at around three years of anti-TNF discontinuation.
Conclusion
Unidentified rare neurological symptoms and demyelinating disease associated with the use of anti-TNF agents can be detrimental to patient treatment outcomes. Emphasis is given on possible avoidance and early identification of exacerbating underlying disease through a detailed neurologic history and use of imaging when suspicion is high. Patients may have no evidence of higher neurological risk prior to starting an anti-TNF treatment. Discontinuation of an anti-TNF agent and subsequent control of disease is possible with alternative immunosuppressive treatments.
Acyl-CoA-Binding Protein (ACBP) genes: Their roles in response to abiotic stress and exogenous hormone application in barley(Hordeum vulgare L.)
Authors: Chang Huayu , Ma Minhu , Gu Mingzhou , Li Shanshan , Li Mengrun , Guo Ganggang , Xing Guofang
Published: January 2024

Background
Acyl-CoA-binding proteins (ACBPs), which are coenzyme A transporters, play important roles in regulating plant growth and development in response to abiotic stress and phytohormones, and in membrane repair. To date, there has not been a comprehensive characterization of the barley (Hordeum vulgare L.) ACBP family.
Results
Eight ACBP genes were identified in the barley genome named HvACBP1–8. These HvACBP genes are specifically expressed in certain tissues and organs, and their expression is induced by abiotic stressors, such as drought, salinity, UV-B exposure, temperature extremes, and exposure to exogenous phytohormones. The HvACBP7 and HvACBP8 amino acid sequences were still conserved during the domestication of Tibetan Qingke barley.
Conclusions
These findings suggest that acyl-CoA-binding proteins could play important in barley growth and environmental adaptation. This study lays the foundation for further analyses of the biological functions of HvACBPs in the barley stress response.

Published: January 2024

Purpose: High-intensity long-interval training (long-HIIT; interval≥1 min; intensity 85%-100% of maximal oxygen uptake [V̇O2max]) is often applied for cardiorespiratory adaptations, however long-HIIT can also challenge the anaerobic and neuromuscular systems. Therefore, this study aimed to investigate the effects of 4-week long-HIIT (11 sessions) on anaerobic capacity, repeated sprint ability (RSA), and neuromuscular function.
Methods: Twenty active men (V̇O2max: 44.8±5.3 mL.kg-1.min-1) performed an incremental running test (TINC), a supramaximal test consisting in running until the task failure at 115% of maximum velocity achieved in TINC (VINC) for anaerobic capacity determination, and a RSA test (2×6×35-m all-out sprints) Pre- and Post-HIIT. Before and after RSA, the neuromuscular function was assessed with counter movement jumps (CMJ) and knee extensors maximal isometric voluntary contractions (MVC) with femoral nerve electrical stimulation. Long-HIIT consisted of 10×1-min runs at 90% of VINC with 1-min recovery.
Results: Long-HIIT induced significant increase in V̇O2max (P=0.0001). Although anaerobic capacity did not change significantly, 60% of the participants improved above the smallest worthwhile change (0.2×standard deviation of Pre-HIIT). The changes in sprint performance over RSA was significantly less post-HIIT than pre (P=0.01). RSA induced significant drop of MVC, high frequency doublet, voluntary activation and CMJ performance at Pre- and Post-HIIT (P<0.01), however, the percentage of reduction from rest to fatigued conditions were not significantly altered at Post-HIIT compared to Pre.
Conclusion: 11 sessions of long-HIIT over 4-week improve maximal aerobic power but not anaerobic capacity, and neuromuscular function. Yet, neuromuscular fatigue was similar despite greater speeds reached during RSA.

Published: January 2024

During the formation of kidney stones, the interaction between stone crystals and tubular epithelial cells (TECs) leads to tubular injury and dysfunction, triggering osteogenic transformation and inflammatory responses. However, the molecular mechanisms underlying these changes in TECs remain elusive. Through high-throughput drug screening, we identified JQ1, an enhancer targeting epigenetic drug, effectively inhibiting the adhesion of calcium oxalate (CaOx) crystals to primary TECs. We further confirmed its therapeutic effect in a glyoxylic acid-induced CaOx nephrolithiasis mouse model. Utilizing comprehensive epigenomic and transcriptomic profiling, we charted dynamic enhancer landscape and gene expression program associated with nephrolithiasis. An integrative bioinformatic analysis uncovered a transcription factor (TF) regulatory network within TECs, pinpointing the nuclear receptor RXRα as a central TF modulating enhancer activity. Importantly, our animal studies revealed that tubular-specific RXRα deletion promoted kidney stone formation, while its activation by Bexarotene (Bex), an FDA-approved drug, mitigated this progression. Mechanistically, under normal circumstances, RXRα inhibited nephrolithiasis-promoting genes by recruiting the HDAC3/SMART transcription suppressor complex to repress enhancer activity. Yet, with the progression of nephrolithiasis, RXRα expression decreased, leading to enhancer activation and subsequent upregulation of nephrolithiasis-promoting genes. Activation of RXRα by Bex suppressed these genes by reprogramming their enhancer profiles. In summary, our work illustrates an epigenetic mechanism underlying TECs fate transition during kidney stone formation and highlights the therapeutic potential of JQ1-mediated enhancer inhibition and Bex-induced RXRα activation in nephrolithiasis management.

Published: January 2024

Background
The Ebola epidemic has persisted in Africa since it was firstly identified in 1976. However, few studies have focused on spatiotemporally assessing the ecological adaptability of this virus and the influence of multiple factors on outbreaks. This study quantitatively explores the ecological adaptability of Ebola virus and its response to different potential natural and anthropogenic factors from a spatiotemporal perspective.
Methods
Based on historical Ebola cases and relevant environmental factors collected from 2014 to 2022 in Africa, the spatiotemporal distribution of Ebola adaptability is characterized by integrating four distinct ecological models into one synthesized spatiotemporal framework. Maxent and Generalized Additive Models were applied to further reveal the potential responses of the Ebola virus niche to its ever changing environments.
Results
Ebola habitats appear to aggregate across the sub-Saharan region and in north Zambia and Angola, covering approximately 16% of the African continent. Countries presently unaffected by Ebola but at increased risk include Ethiopia, Tanzania, Côte d'Ivoire, Ghana, Cameroon, and Rwanda. In addition, among the thirteen key influencing factors, temperature seasonality and population density were identified as significantly influencing the ecological adaptability of Ebola. Specifically, those regions were prone to minimal temperature variations between seasons. Both the potential anthropogenic influence and vegetation coverage have a rise-to-decline impact on the outbreaks of Ebola virus across Africa.
Conclusions
Our findings suggest new ways to effectively respond to smaller potential Ebola outbreaks in Sub-Saharan Africa. We believe that this integrated modeling approach and response analysis provide a framework that can be extended to predict risk of similar epidemiological studies for other diseases across the world.

Authors: Vidal-Verdú Àngela , Torrent Daniel , Iglesias Alba , Latorre-Pérez Adriel , Abendroth Christian , Corbí-Agustín Paola , Peretó Juli , Porcar Manuel
Published: January 2024

Background
Insect gut microbiomes play a crucial role in the insect development by assisting digestion, nutrient acquisition, and detoxification. These microbial communities are shaped, among other factors, by the specialized insect diet habits as well as the morphological structure of the gut. Rose chafers (Pachnoda spp.; Coleoptera: Scarabaeidae), have a highly differentiated gut characterized by a pronounced hindgut dilation which resembles a miniaturized rumen. Specifically, the species Pachnoda marginata shows a very characteristic gut morphology and has not been previously studied in detail in terms of microbial ecology. Here, we describe the complex microbial community along the compartimentalized gut of P. marginata and the potential of its microbiota for biotechnological applications.
Results
Here we show a fine scale study of the highly compartmentalized gut of P. marginata by using amplicon and metagenomic sequencing to shed light on the bacterial, archaeal and fungal communities thriving in each section of the gut. We found a microbial gradient along the gut from aerobic (foregut) to strictly anaerobic (hindgut) communities. In addition, we have characterized interesting biological activities and metabolic pathways of gut microbial communities related to cellulose degradation, methane production and sulfate reduction.
Conclusions
Taken together, our results reveal the highly diverse microbial community and the potential of P. marginata gut as a source of industrially relevant microbial diversity.

Authors: Vamja Roshni , M Yogesh , Patel Monika , Vala Vijay , Ramachandran Arya , Surati Bhumika , Nagda Jay
Published: January 2024

Background
Thyroid dysfunction in pregnancy can adversely impact maternal and fetal outcomes. However, the association between thyroid status and specific adverse outcomes needs clarity, especially in understudied regions.
Objective
This prospective cohort study aimed to illuminate the multifaceted associations between maternal thyroid dysfunction and feto-maternal outcomes in Gujarat, India.
Methods
This hospital-based cohort study recruited and monitored 500 euthyroid, 250 hypothyroid, and 150 hyperthyroid pregnant women until delivery. Maternal thyroid status was determined by serum thyroid stimulating hormone (TSH) and free thyroxine (fT4) levels. Adverse fetal outcomes included preterm birth, neonatal intensive care unit (NICU) admission, respiratory issues, and low APGAR scores. Maternal outcomes included preeclampsia, hemorrhage, hypertension, postpartum thyroiditis, and thromboembolism. Relative risks quantified associations between thyroid dysfunction and outcomes.
Results
Compared to euthyroid women, hypothyroid women had a higher RR for preterm birth (RR 1.8, 95% CI 1.1–3.0), low APGAR score (RR 2.5, 95% CI 1.5–4.1), preeclampsia (RR 3.0, 95% CI 1.9–4.8), postpartum hemorrhage (RR 1.6, 95% CI 1.2–2.1), and venous thromboembolism (RR 3.1, 95% CI 1.7–5.7). Hyperthyroid women had over twice the risk of low APGAR score (RR 1.8, 95% CI 0.9–3.5), neonatal hypoglycemia (RR 1.5, 95% CI 0.5–4.3), respiratory distress (RR 1.4, 95% CI 0.7–2.8), and postpartum thyroiditis (RR 2.3, 95% CI 1.1–4.8).
Conclusion
Maternal thyroid dysfunction escalates risks for adverse fetal and maternal outcomes. Thyroid monitoring and management during pregnancy are critical to mitigate complications.
The Effectiveness of Using Eye Movement Desensitization and Reprocessing Therapy on Reducing the Severity of Symptoms among Individuals Diagnosed with Post-Traumatic Stress Disorder: A Systematic Review
Authors: Haddad Rabia H. , Alhusamiah Bushra Kh. , Haddad Razan H. , Hamdan-Mansour Ayman M. , Abuhashish Younis H.
Published: January 2024

Background: Post Traumatic Stress Disorder (PTSD) is a global-concern mental illness that occurs due to exposure to a traumatic life experience such as a natural disaster, a severe accident, or a physical or sexual assault in adulthood or childhood. The consequence of PTSD warrants mental health professionals to find effective interventions to maintain and restore mental-well-being. Therefore, selection of intervention is a cornerstone element in deciding successful interventions.
Objectives: The aim of this systematic review was to evaluate and summarize the effectiveness of using eye movement desensitization and reprocessing (EMDR) intervention among individuals diagnosed with PTSD. As well as to highlight the standardized EMDR-based-interventional protocol.
Data source: The relevant literature was extracted and conducted using the following online bibliographic databases: Cumulative Index to Nursing and Allied Health Literature (CINAHL), ProQuest, MEDLINE, Google Scholar, SAGE Journals, and Science Direct and by hand checking reference lists of past similar reviews.
Methods: This Systematic review is guided according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standards. Several online databases were used in searching for eligible studies in peer-reviewed journals relevant to the study keywords. The included studies were Systematic reviews and clinical trials which used EMDR intervention among patients experiencing PTSD symptoms, older than 18 years and were published in the English language from 2017 to 2022. Three researchers independently contributed to study selections, data extraction and study evaluations from different aspects: including quality assessment, risk of bias, and study synthesis.
Results: A total of eight published studies met the inclusion criteria and were included in this systematic review; four articles were randomized controlled trials and four were systematic review and meta-analysis studies. In all included studies, the EMDR was utilized as a primary psychotherapy intervention for PTSD symptoms. The results of this extensive and comprehensive review showed that EMDR is an effective psychotherapeutic intervention to reduce and control the severity of symptoms among individuals with PTSD.
Conclusions: This Systematic review gives an overview and explains strong supportive evidence for effectiveness of the EMDR interventions among individuals with PTSD. Therefore, EMDR therapy could be assumed as one standard treatment option for PTSD aiming at reducing treatment duration, and cost of treatment, and restoring the mental well-being and functionality of those suffering from PTSD.
Poly(lactic acid)/ poly(ε-caprolactone) blends: the effect of nanocalcium carbonate and glycidyl methacrylate on miscibility
Authors: Negaresh Mohammadmahdi , Javadi Azizeh , Garmabi Hamid
Published: January 2024

To expand the potential applications of polylactic acid (PLA), it is essential to incorporate a highly flexible polymer into the blend. Polycaprolactone (PCL) is an ideal choice due to its ductility and biodegradability. However, blending PLA with PCL results in weak mechanical properties. To address this issue, glycidyl methacrylate (GMA) and nano calcium carbonate (NCC) were introduced to enhance the adhesion at the interface between PLA and PCL. SEM images provided clear visual evidence of the impact of GMA and NCC on the morphology of the blend. Both components were effective in reducing the size of the dispersed PCL phase, shrinking it to approximately half the size of the original blend. Spectroscopic analysis revealed that GMA caused a reaction between its epoxy group and the hydroxyl and carboxyl groups of PLA and PCL. This reaction led to the formation of strong peaks in the 6.5 to 7.5 range in 1H NMR, as well as peaks at 76 and 139 ppm in 13C NMR. These findings were further corroborated by FT-IR, which demonstrated that NCC, despite its surface coating, did not create any new bonds. Rheological studies further demonstrated the positive effects of GMA and NCC. Both the storage modulus (G') and complex viscosity (η*) of the blends increased, showing improved post-processing performance. Investigation into the shear-thinning behavior of the uncompatibilized blends revealed that NCC caused a significant decrease in complex viscosity at higher frequencies, indicating the disruption of the nanoparticle network. The power-law slope was measured to be 0.62. In contrast, the blend containing the compatibilizer demonstrated a moderate decrease in viscosity, with a power-law slope of 0.36. To analyze the behavior of the PLA/PCL blends in the presence of compatibilizers and nanoparticles at intermediate frequencies, the Palirene model was utilized. The superior integrity of the compatibilized blend was effectively demonstrated by the model, which showed enhanced stress transfer and phase relaxation.

Published: January 2024

The rational construction of heterostructures plays a pivotal role in enhancing both the separation of photogenerated carriers in semiconductors and the photocatalytic activity. This paper successfully constructs a novel BiPO4@ZnWO4 p-n type heterojunction photocatalyst by hydrothermal and ultrasonic stirring methods. The BiPO4@ZnWO4 heterojunction exhibits outstanding photocatalytic performance, achieving a degradation efficiency of 99% for rhodamine B (RhB) under visible light illumination in just 40 min. Furthermore, its photocatalytic reaction rate constant is 3.9 and 96.51 times higher than that of pure ZnWO4 and BiPO4, respectively. Electrochemical characterization demonstrates a more robust photocurrent response and lower resistance in the composite sample, facilitating efficient transport of photogenerated carriers. In addition, the 20% BiPO4@ZnWO4 heterojunction also exhibits desirable photodegradation stability, maintaining a RhB removal rate above 80% even after 5 cycles. Within the context of the photocatalytic reaction system, the superoxide radical (·O2-) plays a key role, succeeded by the hydroxyl radical (·OH) and the photoinduced hole (h+). This paper provides a feasible p-n type heterojunction photocatalyst for the treatment of dyeing wastewater.

Authors: Xiangrong Liao , Photong Chonlatee , Su Jianbin
Published: January 2024

Power characteristics are important indicators of fuel cell performance. In the actual operation of fuel cells, changes in operating conditions lead to variations in their power characteristics. Therefore, it is imperative to explore the impact of operating conditions on power characteristics. This paper analyzes the factors influencing fuel cell power and uses sensitivity analysis to investigate how different factors affect fuel cell performance. The operating parameters are optimized using a Bayesian-optimized Gaussian process regression model. The research results indicate that temperature has the greatest impact on fuel cell power, followed by stoichiometry and backpressure. The Bayesian-optimized Gaussian process regression model performs the best, reducing its RSME from 0.1 to 0.0556. Residual analysis and regression characteristic analysis verify the optimized model's improved fitting and regression characteristics. Based on the Bayesian-Gaussian process regression model, the optimized operating parameters are obtained for maximum power: a temperature of 80°C, stoichiometry of 4, and backpressure of 1.7 bar. This paper provides theoretical support for improving fuel cell performance.。

Published: January 2024

This paper develops robust economic models for nowcasting Indonesia's GDP growth. Utilizing a comprehensive dataset comprising monthly economic and finance indicators from 2013 to 2023, we explore their association with GDP growth. The study period spans from January 2013 to December 2022 for in-sample data, with an extension to September 2023 for out-sample analysis. We employ a suite of machine learning models - Elastic Net, Random Forest, XGBoost, and SVM - selected for their complementary strengths. The models are trained and tested, yielding an RMSE range of 0.01 to 0.41 for the training period and a narrower range of 0.11 to 0.17 for the testing period, indicating robust performance across different economic conditions, including normal and pandemic periods. A key aspect of our study is the model interpretation, which includes decomposition and Shapley value analysis, providing insights into the driving factors behind GDP fluctuations. Our findings highlight the significant impact of several indicators on Indonesia's GDP. Additionally, our nowcasting exercise for Q4 2023 projects an average GDP growth of 5.13%, ranging from 5.01–5.26%.

Background: Many view attrition as one of the biggest barriers to effective delivery of cART in resource-limited settings in sub-Saharan Africa (SSA). In this study, our objective was to describe the incidence and predictors of attrition among adults enrolled in cART programs in two referral hospitals in the northern coastal areas of Eritrea.
Methods: This was a retrospective review of patient records of 464 patients [Male: 149(35.6%) vs. Females: 269(64.4%)] aged 18 years who initiated cART between 2005 and 2021. The main outcome measures were attrition (loss-to-follow-up (LTFU) plus mortality) and associated outcomes. Kaplan-Meier statistics were used to evaluate survival probability of attrition. Independent predictors of attrition were evaluated using a multivariable Cox proportional hazard model.
Results: A total of 418 patients [Male: 149(35.6%) vs. Female: 269 (64.4%)] were studied. At baseline, the mean (±SD) age (SD) was 34(±11.2) years; median (±IQR) CD4+ T-cell count was 151 (IQR: 87-257) cells/µL. After a follow-up time of 39,883 months, 127 ((30.4%), 95% CI [26-35]) attrition events were reported, translating into a cumulative incidence of 2.9/1000(2.4-3.5) per 1,000 people-months (PMs) were reported. During the same period, 97 (23.11%) patients died, 32(7.7%) were LTFU, and 47(11.2%) transferred out. In the adjusted multivariate Cox regression model, an increased risk of attrition was associated with the year of enrollment (aHR = 1.07, 95% CI 1.00-1.15, p-value = 0.04); ethnicity (Afar: aHR=3.21, 95% CI: 1.84-5.59, p value < 0.001) (Others: aHR = 2.67, 95% CI: 1.14-6.25, p value = 0.024) and cART backbone: (TDF+FTC: aHR=2, 95% CI: 1.21-3.32, p value = 0.007). On the contrary, the risk of attrition decreased per unit increase in baseline CD4+ T-cells/μL (uHR=0.998, 95% CI 0.996-0.999, p-value<0.001).
Conclusion: Despite expanded treatment and decentralization of cART programs, mortality due to advanced disease at enrollment remains high in peripheral settings. A concerted effort is required to reduce late enrollment and improve the management of patients with advanced disease in decentralized programs.
Antenna environment's effects on elevation angle dependent ionosphere-free phase residuals, and geodetic monument noise in the Topo-Iberia CGPS network
Authors: García-Armenteros Juan A.
Published: January 2024

The purpose of this study was determine for the first time the relationship between the antenna environment and the elevation angle dependent ionosphere-free phase residuals from the GAMIT/GLOBK processing of the Topo-Iberia network (2008-2019), as well as the relationship between the geodetic monument type used and noise. The pattern formed by the trace of the elmean residuals has been associated with the antenna environment characteristics, and five pattern types have been established. A diagram of pattern types has also been created for the first time that could be useful to select the optimal GNSS antenna environment. A new metric has been proposed to quantify the differences between patterns, the phase residuals pattern difference index (PRPDI), which has turned out to be a good tool to identify antenna environment changes, as well as the best and worst quality stations. According to the results, the highest PRPDI values correspond to the poorest quality stations and those that have shown changes in the occlusion horizon. The results also reveal that the smallest elmean phase residuals are produced by antenna environments with uneven ground and vegetation cover (RMS of 0.6 mm at ASIN station), and the highest residuals occur in environments associated with monuments on flat roof of buildings (RMS of 3.1 mm at BENI station). The Topo-Iberia stations with standard pillars on bedrock and shallow-drilled braced monuments present less noise than those with little pillars and monuments on buildings. The results regarding the least noisy monument types agree with those of previous publications. The Topo-Iberia monuments present a random-walk noise level adequate for a geodetic monument. No relationship between noise and geographical location of the sites has been observed, but between seasonal noise and the antenna environment.

De hecho, su institucionalización se dio durante los siglos XVIII-XIX, pasando de ser un evento hogareño y asistido por mujeres a realizarse en los centros de salud incipientes y a cargo de los nuevos profesionales médicos. Este artículo analiza el parto/nacimiento institucional en relación con el capitalismo como modo de (re)producción de bienes y personas, partiendo de la hipótesis de que este se encuentra regido por la lógica capitalista de organización espaciotemporal y de relación social. Mediante una reconstrucción teórica, se articulan categorías de la teoría marxiana del valor —atendiendo a sus derivas desde los feminismos— con producciones teóricas enfocadas desde la antropología de la reproducción, explorando cruces y relaciones entre estos campos conceptuales dada la vacancia de desarrollos en esta dirección. De esta manera, se proponen líneas para pensar el modelo institucional de partos desde una perspectiva marxista y en clave de género.
Percepciones de los niños y niñas sobre la experiencia de juego y el aprendizaje con Nintendo Labo: múltiples experiencias de “hacer y jugar”
Authors: Cano John , Chow Megan
Published: January 2024

Este artículo explora las percepciones de niños y niñas que tuvieron la oportunidad de explorar las fases de “Hacer” y “Jugar” del Kit de variedad “Toy-Con 01” del Nintendo Labo. A través de aspectos claves como el involucramiento/compromiso estudiantil, la utilización del conocimiento y la adquisición de nuevos conceptos (Gee, 2008), este artículo amplía la comprensión general de cómo los videojuegos pueden generar un aprendizaje activo. A partir de las experiencias en la construcción de proyectos de “Hazlo tú mismo”, los autores analizan cómo los niños, a través de cuatro casos diferentes, conectaron sus conocimientos y experiencias previas con contenido relacionado con la ciencia (implícito en las interacciones y el hardware de la consola Nintendo Switch y el software Nintendo Labo y piezas de cartón). Las limitaciones del estudio sugieren que se necesita más tiempo para tener una exploración más profunda de las percepciones de los niños explorando la fase “Descubrir”—la tercera y última fase de Nintendo Labo.

“Yo no juzgo a las personas”. Probablemente el lector haya escuchado esta expresión en más de una ocasión. La realidad, no obstante, es muy diferente. Si algo hemos aprendido de décadas de investigación en los sesgos derivados de la percepción facial, es que los juicios asociados a las primeras impresiones resultan virtualmente inevitables. Se podría decir que estamos predeterminados para juzgar, pese a que no siempre lo hacemos intencionalmente.
Corporate governance report compliance rate and accounting conservatism: New evidence from Korea
Authors: Seok Choo Hyoung , Cho Sun-ae , Emilia Lee Jeongeun
Published: January 2024

This study investigates the relationship between the corporate governance report (CGR) compliance rate and a company’s accounting conservatism, utilizing the CGR compliance rate as a novel method to evaluate the effectiveness of corporate governance practices. Given the challenges of applying global indices to measure corporate governance in the Korean market, this study focuses on the CGR compliance rate as a key indicator. Utilizing the ordinary least squares (OLS) regression model, specifically the Ball and Shivakumar (2005) model widely employed in previous studies to assess accounting conservatism, this paper conducts empirical analyses based on 784 observations from Korean listed firms between 2018 and 2021. The main analysis reveals a positive association between the CGR compliance rates (coef = –2.416, p-value < 0.01) and accounting conservatism. A fixed-effect model and a propensity score matching (PSM) model also show a positive association between the CGR compliance rates, respectively (coef = –2.507, p-value < 0.01; coef = –3.118, p-value < 0.1) and accounting conservatism. This study proves that firms with high CGR compliance rates tend to promptly recognize financial losses in financial reporting, thereby safeguarding investors. This suggests that investors should consider the CGR compliance rates when evaluating potential investments. Overall, these findings contribute to validating the CGR compliance rates as a valuable proxy for assessing corporate governance practices in Korean firms.
Intimate Partner Violence in Nigeria: A Review of the Literature
Authors: Mukaddas Halima
Published: January 2024

Intimate Partner Violence (IPV) is a pervasive human rights issue of great public health importance in Nigeria. This article aims to review and synthesize available knowledge on Intimate Partner Violence in Nigeria and provides information that fills the knowledge gap noted in international and global reports related to Nigeria’s experiences. A literature search was conducted on empirical studies in English using the keywords ‘Intimate, Partner, Violence, IPV AND Nigeria.’ The databases searched were Research for Life r4Life, Google Scholar and ProQuest Central and the articles included in this review cover studies published from 2008 to 2023. The results show that IPV studies have multidimensional approaches and are influenced by multi-level predictors across cultural, socioeconomic, and educational factors. Interventions are therefore multiprong to address specific aspects depending on the context. Regional differences exist giving varied results, each community setting may have peculiarities that cannot be generalized to every Nigerian community. Future research should focus on large-scale community-based primary research to address IPV. Keywords: ‘Intimate, Partner, Violence, Domestic Violence, IPV AND Nigeria.

Sexually transmitted infections (STIs) represent a major public health concern for young people in developing nations, impacting approximately two-thirds of individuals below the age of 25. This study examined the prevalence and the association between self-reported STIs, childhood violence exposure, and mental health outcomes among adolescents and young adults (13-24 years old) in Zimbabwe. Secondary data from the 2017 Zimbabwe Violence Against Children and Youth Survey (n=8,715) was utilized. Data analysis was performed using chisquare to determine the prevalence estimates for bivariate. Seven logistic regression models were used to examine the significant association between independent variables and outcomes for multivariate. About 45.5% of adolescents and young adults with self-reported STIs were exposed to multiple forms of childhood violence, 49.8% reported lifetime suicide risk, and 44.9% reported moderate-to-severe mental distress in the past 30 days. Furthermore, logistic regression results indicated that adolescents and young adults with self-reported STI diagnoses were more likely to be exposed to multiple forms of childhood violence, including physical, emotional, and sexual violence, as well as mental distress in the past 30 days and lifetime suicide risk compared to those without STIs. Therefore, this study underscores the importance of implementing comprehensive public health strategies to protect the wellbeing of adolescents and young adults with STIs. Interventions should also prioritize raising awareness, destigmatizing STIs, implementing and strengthening violence prevention policies, and addressing mental health problems through community mental health treatment programs in Zimbabwe. Keywords: Childhood violence, Emotional violence, Exposure, Mental distress, Physical violence, Sexual violence, Sexually transmitted infections (STIs), Suicide risk, Zimbabwe.
Quality management in animal farming
Authors: Soloshenko Vladimir , Mager Sergey
Published: January 2024

The article introduces a long-term analysis of statistics and experimental research in domestic animal farming. Dairy cattle breeding is the dominant industry in Russian livestock farming. Its annual productivity has reached 6000 kg of milk per cow, while some farms and regions have brought this indicator up to 8000–10 000 kg. Unfortunately, the quality of milk, meat, and other livestock products is often neglected in favor of productivity.

Human health is believed to depend on nutrition. However, this dependence requires more specific evidence. For instance, the exact effect of livestock product quality management on the life and longevity of the population still remains unknown. Some studies revealed that pig breeds differ in the cholesterol status of fat; other research teams invented a high-quality green alfalfa dry feed, which provides animals with biologically active substances and normalizes metabolic processes.

This review highlights some promising scientific directions in fundamental and applied knowledge that can be beneficial to human health.

Published: January 2024

Cardiovascular diseases remain a major cause of morbidity and mortality worldwide. Cardiovascular diseases associated with metabolic disorders are collectively referred to as Cardiometabolic Diseases (CMDs). Oxidative stress and inflammation are key contributors to the development and progression of CMDs. Antioxidants and anti-inflammatory agents have garnered significant attention as potential therapeutic strategies for preventing and managing cardiovascular disorders. To better understand the complex interactions between oxidative stress, inflammation, and cardiovascular health, this review paper will focus on the mechanisms of action and potential advantages of antioxidants and anti-inflammatory drugs in reducing the risk factors associated with CVDs and enhancing cardiovascular health in general.

Published: January 2024

Background: Tobacco smoke exposure induces intima-media thickness by reducing nitric oxide and increasing adhesive molecule activity, with circulating cotinine serving as a marker; we hypothesize a correlation between monocyte chemoattractant protein-1 (MCP-1) and carotid intima-media thickness (cIMT) in active male smokers. Material and Methods: We conducted an observational cross-sectional analytic study involving 125 male participants, with 62 being active tobacco smokers and 63 non-smokers. Data were presented as mean ± SD, and the correlation between variables was analyzed using Pearson correlation. Result: Cotinine and MCP-1 levels were significantly higher in the smoker population (p 0.000) compared to non-smokers. The incidence of positive cIMT findings was higher in the smoker group (5%) than in the non-smoker group (2%). In the active smoker population, cotinine (r 0.21; p 0.11) showed a positive but non-significant correlation with positive cIMT findings, while MCP-1 showed a negative correlation (r -0.19, p 0.14) with positive cIMT findings. Smoking duration (r 0.162; p 0.223) and the amount of tobacco smoke (r 0.003; p 0.982) demonstrated a positive correlation with cotinine. MCP-1 exhibited a non-significant positive correlation with smoking duration (r 0.122; p 0.345) and a non-significant negative correlation with the amount of tobacco smoke (r -0.002; p 0.989). Conclusion: Among active tobacco smokers, cotinine showed a positive but non-significant correlation with positive cIMT findings, while MCP-1 exhibited a non-significant negative correlation with positive cIMT findings.
