ÇEVRESEL, SOSYAL VE KURUMSAL YÖNETİŞİM (ESG) PERFORMANSININ DENETÇİ GÖRÜŞLERİ ÜZERİNDEKİ ETKİSİ: BİST’TE BİR UYGULAMA
Authors: Kurt Yusuf , Güngör Karyağdı Nazan , Kara Murat
Published: March 2024

Araştırmada 2018-2022 yılları arasında Borsa İstanbul’da (BIST) kesintisiz işlem gören işletmelerin yayımladıkları finansal tablolara bağımsız denetçiler tarafından verilen görüşler üzerinde, çevresel, sosyal ve kurumsal yönetim performanslarını ifade eden ESG skorlarının bir etkisinin olup olmadığının tespit edilmesi amaçlanmıştır. Çalışmada ESG performansı bağımsız değişken olarak, işletme büyüklüğü, dönem net kârı, esas faaliyetlerden/bankacılık faaliyetlerinden elde edilen nakit akışları ve kaldıraç oranı değişkenleri ise kontrol değişkenleri olarak dikkate alınmıştır. Değişkenler arasındaki ilişkilerin ölçümünde lojistik regresyon analizi yöntemi tercih edilmiştir. Çalışmada ESG performansı yüksek olan işletmelerin, ESG performansı düşük olan işletmelere göre hileli veya yanıltıcı finansal raporlamaya başvurma eğilimlerinin daha az olduğu tespit edilmiştir.
Monitoring of Single-Post Free-Standing Supports of Overhead Power Lines under the Action of Wind Loads
Authors: TANASOGLO A.V. , GARANZHA I.M. , FEDOROVA S.R.
Published: March 2024

Experimental studies of the dynamic behavior of metal supports of an overhead line (OL) under the action of wind loads are presented. The methodology and scheme of the experiment execution in two stages on the anchor-angular and intermediate supports of the 220 kV overhead line “Zmiev TPP – Zalyutino” have been developed. At the first stage, the excitation of vibrations of the support structures was achieved using wind action, at the second stage, free vibrations of the “support – wires” system were recorded, which were created using manual resonance. Graphs of stress changes in structural elements of tower lattice supports in the wind along and across the overhead line are presented. The main natural frequencies of vibrations of metal supports have been experimentally determined, which are displayed on the free vibration damping graphs. Analysis of the obtained spectra of longitudinal pulsations of wind speed made it possible to conclude that the wind flow is stationary. The necessity of frequency detuning of the overhead line support structure from the natural frequency of 2.2 Hz has been established, since an external effect with this frequency is possible when the live wire breaks in one of the phases. It is necessary to improve not only the principles of monitoring and observing the behavior of structures in the wind flow, but also to develop simple methods to take into account the dynamic component under the action of natural-climatic and emergency loads, which by their nature are dynamic phenomena.
The Effect of a Hot Humid Climate on Corrosion of Reinforced Concrete
Authors: ROZENTAL N.K.
Published: March 2024

The expansion of economic cooperation with countries located in areas with hot, humid climates and the construction of reinforced concrete buildings and structures in coastal zones of non–freezing seas poses the task of assessing the impact of climate on the corrosive state of reinforced concrete structures, primarily carbonation of concrete and seawater aerosol containing chlorides. The effect of low negative temperature is not considered in this work. The data on the carbonation of concrete under conditions of increased insolation and the action of sea salt aerosol are summarized, mainly using the example of the hot humid climate of Cuba for further development of research, and subsequently the development of standards for protection against corrosion and carbonation of concrete and steel reinforcement in areas with a tropical climate. Based on the results of a survey of the condition of reinforced concrete structures and structures manufactured and erected in Cuba, as well as the results of observations, the results of an analysis of aggressive environmental factors of the Republic of Cuba affecting the corrosion of reinforced concrete structures, the results of studies of concrete carbonation and the effects of sea salt aerosol are presented. When designing and building structures on the seashore by domestic organizations in countries with hot, humid climates, the aggressive effects of seawater aerosol and accelerated carbonation of concrete, which reduce the durability of reinforced concrete structures, should be taken into account.

Published: March 2024

The results of studies to determine the effect of introducing a complex additive of carbon nanotubes and plasticizer into the composition of fine-grained concrete are presented. Two series of tests of beam samples were performed, and the strength characteristics of the studied compositions were determined. Two methods of introducing nano-additives into concretes were compared: using an ultrasonic dispersant and a linear induction wave action apparatus (LIA) by analyzing two series of tests of different compositions. It was established that the introduction of nanotubes using LIA provides a minimally greater increase in the compressive strength due to the activation of the cement binder by means of regrinding. However, the maximum increase in strength is achieved equally for each of the injection methods.
Gender, Ethnicity, and Individual Resistance

In this article, I explore Sibirskiy dnevnik (henceforth Siberian Diary) of Arpenik Aleksanyan, a Soviet student of Armenian origin who, together with her family, was exiled to Siberia in one of the late Stalinist deportations of ethnic minorities. Arpenik's diary provides a unique perspective on forced displacement and exile through the eyes of a young woman. I treat the diary both as an historical source revealing gendered experiences of forced displacement and as autobiographical writing that provides a glimpse into late Stalinist girlhood and young women's subjectivity. I provide a reading of Siberian Diary that reveals Arpenik's seemingly contradictory integration of Stalinist ideologies of the so-called new woman and nationalities as a foundation for self-construction as well as individual resistance to persecution.

Previous studies have shown that dietary copper deficiency causes cardiac hypertrophy and depression of vascular epithelial growth factor (VEGF) expression in mouse model. Copper replenishment in the diet reverses cardiac hypertrophy and restores VEGF expression. The present study was undertaken to specifically determine the role of VEGF in copper effect on cell hypertrophy. Embryonic rat cardiac H9c2 cells were exposed to hydrogen peroxide to develop hypertrophy, determined by increases in cell size and total protein content. Copper addition at 5 μ M in cultures suppressed cell hypertrophy. In the presence of anti-VEGF antibody, copper inhibitory effect on cell hypertrophy was blunted, and VEGF alone mimicked the inhibitory effect of copper. The results thus demonstrated that VEGF is critically involved in copper inhibition of cell hypertrophy induced by hydrogen peroxide in the H9c2 cells.

The mechanism of adenosine A1 receptor–induced intrarenal vasoconstriction is unclear; it depends on sodium intake and may be mediated by changing the intrarenal activity of the nitric oxide (NO) and/or cyclooxygenase (COX) pathway of arachidonic acid metabolism. The effects of 2-chloro-N6-cyclopentyl-adenosine (CCPA), a selective A1 receptor agonist, on renal hemodynamics were examined in anesthetized rats maintained on high sodium (HS) or low sodium (LS) diet. Total renal (i.e., cortical) blood flow (RBF) as well as superficial cortical (CBF), outer medullary (OMBF), and inner medullary (IMBF) flows were determined by laser-Doppler. In HS rats, suprarenal aortic infusions of 8–40 nmol/kg/hr CCPA decreased IMBF (15%) and other perfusion indices (22%–27%); in LS rats, IMBF increased 3% (insignificant) and other indices decreased 13%–24%. In LS rats, pretreatment with N-nitro-L-arginine methyl ester prevented the A1 receptor–mediated decrease in RBF and CBF but not OMBF; the response in IMBF was not altered. Pretreatment with indomethacin prevented the decreases in RBF, CBF, and OMBF and did not change the response of IMBF. Thus, within the cortex the vasoconstriction that follows A1 receptor activation results both from inhibition of NO synthesis and from stimulation of vasoconstrictor products of the COX pathway. In the outer medulla, the latter products seem exclusively responsible for CCPA-induced vasoconstriction. The observation that in LS rats IMBF was not affected by stimulation of adenosine A1 receptors suggests that limiting salt intake may help protect medullary perfusion against vasoconstrictor stimuli which have the potential to disturb long-term control of arterial pressure.

Improving the performance of damage repair in thin-walled structures with analytical data and machine learning algorithms
Authors: Shaikh Abdul Aabid , Raheman Md Abdul , Hrairi Meftah , Baig Muneer
Published: March 2024

In the last four decades, bonded composite repair has proven to be an effective method for addressing crack damage propagation. On the other hand, machine learning (ML) has made it possible to employ a variety of approaches for mechanical and aerospace problems and such significant approach is the repair mechanism and hence ML algorithms used to enhance in the present work. The current work investigates the effect of the single-sided composite patch bonded on a thin plate under plane stress conditions. An analytical model was formulated for a single-sided composite patch repair using linear elastic fracture mechanics and Rose's analytical modelling. From the analytical model, the stress intensity factors (SIF) were calculated by varying all possible parameters of the model. Next, ML algorithms were selected, and comparative studies were conducted for the best possible performance and to identify the parametric effects on optimum SIF. Also, the analytical model is validated with existing work, and it shows good agreement with less than 10% error. This study is particularly important for designing the single-sided composite patch repair method based on analytical modelling. Also, it is important to compare ML algorithms with analytical solutions in regression applications.

Authors: Feklistova Eugeniia , Mugatarov Artur , Wildemann Valeriy , Agishev Anton
Published: March 2024

This work is devoted to the fracture processes numerical modeling of elastic-brittle bodies taking into account the statistical distribution of subregions strength values and stress concentration. The novel formulation of the boundary value problem and its solution algorithm are developed. The loading diagrams obtained in computational simulations, the corresponding growth curves of the destroyed elements relative number and the damaging process kinetics are analyzed. The presence of the postcritical deformation stage at the macro-level is noted. The influence of the strength properties distribution range and the depth of the concentrator on the maximum load value and the damage evolution is determined. The significant influence of the finite elements’ properties distribution on the fracture processes modeling results is concluded.
Development of small businesses producing cereals, legumes, and sunflower seeds in wartime conditions
Authors: Malik Mykola , Kravchenko Svitlana , Shpykuliak Oleksandr , Hudz Henrikh
Published: March 2024

Small businesses producing cereals, legumes, and sunflower seeds contribute to the country’s food security and environmental protection potential. The purpose of this study was to substantiate the social, economic, and conceptual foundations of small business entities’ activities in the production of cereals, legumes, and sunflower seeds in modern conditions. The methodological framework of the study included the provisions of institutional economic theory and functional analysis. To generalise the results, the study employed analysis, graphic, and abstract-logical methods, and approaches of generalisation of results. The motivational orientation of the functioning of small businesses engaged in the production of cereals, legumes, and sunflower seeds and their place in production and consumption were determined. The study found that in 2023, the company achieved a record grain yield of 51.8 100 kg/ha, which was driven by favourable weather conditions. It was substantiated that the cost of crop production has increased due to lower prices for agricultural products (maize by -41%; sunflower by -35%; wheat by -37%) and an almost twofold increase in the cost of plant protection products and fuel. It was proved that in 2017-2022, 91.79% of the variation in net profit is explained by the variation in the level of grain, legumes, and sunflower seeds sold by small businesses. It was found that the disruption of the sales system of small businesses producing cereals, legumes, and sunflower seeds, the low level of purchase prices and the considerable increase in prices for material and technical sources of survival and fertilisers due to the hostilities make production inefficient. The development of small businesses and family farming stays one of the priority areas of regional policy. The information and analytical material can be considered when creating regional programmes for the development of agrarian entrepreneurship.
Attention-Deficit/Hyperactivity Disorder as a Potential Risk Factor for Dementia and Other Neurocognitive Disorders: A Systematic Review
Authors: Carr Rachel H. , Eom Gina D. , Brown Eric E.
Published: March 2024

Background:

Attention-deficit/hyperactivity disorder (ADHD), a common neurodevelopmental condition now recognized to persist into older adulthood, has been postulated to be a risk factor for neurocognitive disorders given the overlap in clinical features and neurobiology, as well as the complex interplay between ADHD and known risk factors for dementia. Studies have emerged assessing this relationship, but there has not yet been a comprehensive systematic review addressing this topic.

Objective:

To assess whether ADHD is a risk factor for neurocognitive disorders and to explore possible mechanisms for such an association.

Methods:

A systematic review of the literature was conducted using Medline, Embase, and PsycINFO from inception until June 4, 2023. Studies were included if they assessed whether or how ADHD may be a risk factor for neurocognitive disorders. Studies were excluded if they were not primary literature, not published in a peer-reviewed journal, not in English, and/or used non-human subjects. Study quality was assessed using the QualSyst tool.

Results:

Sixteen studies met inclusion criteria. Seven studies found a positive association between ADHD and neurocognitive disorders (all-cause dementia in four studies, Alzheimer’s disease in three studies, Lewy body dementia in two studies, and mild cognitive impairment in one study). Four studies did not find an association. Five studies pertained to possible mechanisms for an association, including genetics, with minimal significant findings.

Conclusions:

ADHD may be a risk factor for certain neurocognitive disorders, although the evidence base is limited, and the absolute risk is small. Possible explanations include genetic and lifestyle factors.
Investigating the tolerance of different strawberry cultivars to Botrytis cinerea infection and its relation with fruit quality
Authors: Qaderi Rohullah , Mazzoni Luca , Tonanni Virginia , Gagliardi Francesco , Capriotti Luca , Pergolotti Valeria , Diaz Yasmany Armas , Capocasa Franco , Mezzetti Bruno
Published: March 2024

BACKGROUND:

Strawberries are a delicate, high nutritional value fruit with an extremely short shelf life and high susceptibility to tissue infection, mainly by Botrytis cinerea. Control of the disease requires an extensive amount of fungicide that is applied in varying complexes because the pathogen easily develops resistance against the active compounds. Planting tolerant cultivars seems to be a promising alternative for fruit growers, but there are currently no cultivars available combining tolerance to B. cinerea with attractive horticultural traits.

OBJECTIVE:

In this study, four well-defined strawberry cultivars (‘Romina’, ‘Cristina’, ‘Silvia’, and ‘Sibilla’) were selected and tested under treatment with Botrytis cinerea to determine the tolerance of each cultivar and its association with fruit quality.

METHODS:

Fruits were harvested and then stored for four days after inoculation (treatment) or not (control) with spores of B. cinerea; then, every day the level of decay was detected, and fruits were frozen for successive evaluation of fruit quality.

RESULTS:

The ‘Silvia’ cultivar is the one that demonstrated a higher level of tolerance to Botrytis infection during the treatment, and the ‘Romina’ cultivar was the cultivar most susceptible to the treatment. The results of the study also highlighted qualitative changes in all strawberry cultivars infected with Botrytis cinerea, by a decrease in the soluble solids content and an increase of acids. Generally, in all cultivars, phenolic acids, and vitamin C decreased in both control and infected but there was a strong decrease in infected fruit compared to control. Anthocyanin content increased in control fruits but strongly decreased in infected.

CONCLUSION:

As a preliminary outcome, a positive correlation was obtained between fruit nutritional quality and tolerance to decay, as a high amount of nutritional compound content provides lower susceptibility of fruits to Botrytis cinerea. To confirm this result more studies need to be done.
DySMA – an Instrument to Monitor Swallowing Function in Children with Spinal Muscular Atrophy ages 0 to 24 Months: Development, Consensus, and Pilot Testing
Authors: Zang Jana , Witt Stefanie , Johannsen Jessika , Weiss Deike , Denecke Jonas , Dumitrascu Charlotte , Nießen Almut , Quitmann Julia Hannah , Pflug Christina , Flügel Till
Published: March 2024

Background:

The manifestation of bulbar symptoms, especially swallowing, is important for evaluating disease-modifying therapies for spinal muscular atrophy (SMA). Due to the lack of instruments, the topic is still underrepresented in research.

Objective:

This study aimed to develop a tool to monitor swallowing development in children aged 0 to 24 months with SMA.

Methods:

The method was guided by the COSMIN guidelines and followed a multi-stage Delphi process. The first step was a rapid review of swallowing outcomes in children with SMA younger than 24 months. In the second step, online group interviews with experts ( n = 7) on dysphagia in infants were conducted, followed by an anonymous online survey among experts in infants with SMA ( n = 19). A predefined consensus threshold for nominal scaled voting was set at≥75 % and for 5-point Likert scale voting at 1.25 of the interquartile range. The third step was the pilot test of the instrument, performed with three groups (healthy controls n = 8; pre-symptomatic n = 6, symptomatic n = 6).

Results:

Based on the multi-level interprofessional consensus, the DySMA comprises two parts (history and examination), ten categories, with 36 items. Implementation and scoring are clearly articulated and easy to implement. The pilot test showed that swallowing development could be recorded in all groups.

Conclusion:

The DySMA is well suited for monitoring swallowing development in pre-symptomatic and symptomatic treated infants with SMA. It can be performed in a time-efficient and interprofessional manner. The resulting score is comparable to results from other instruments measuring other domains, e.g., motor function.
Neural Oscillations and Functional Significances for Prioritizing Dual-Task Walking in Parkinson’s Disease
Authors: Huang Cheng-Ya , Chen Yu-An , Wu Ruey-Meei , Hwang Ing-Shiou
Published: March 2024

Background:

Task prioritization involves allocating brain resources in a dual-task scenario, but the mechanistic details of how prioritization strategies affect dual-task walking performance for Parkinson’s disease (PD) are little understood.

Objective:

We investigated the performance benefits and corresponding neural signatures for people with PD during dual-task walking, using gait-prioritization (GP) and manual-prioritization (MP) strategies.

Methods:

Participants (N = 34) were asked to hold two inter-locking rings while walking and to prioritize either taking big steps (GP strategy) or separating the two rings (MP strategy). Gait parameters and ring-touch time were measured, and scalp electroencephalograph was performed.

Results:

Compared with the MP strategy, the GP strategy yielded faster walking speed and longer step length, whereas ring-touch time did not significantly differ between the two strategies. The MP strategy led to higher alpha (8–12 Hz) power in the posterior cortex and beta (13–35 Hz) power in the left frontal-temporal area, but the GP strategy was associated with stronger network connectivity in the beta band. Changes in walking speed and step length because of prioritization negatively correlated with changes in alpha power. Prioritization-related changes in ring-touch time correlated negatively with changes in beta power but positively with changes in beta network connectivity.

Conclusions:

A GP strategy in dual-task walking for PD can enhance walking speed and step length without compromising performance in a secondary manual task. This strategy augments attentional focus and facilitates compensatory reinforcement of inter-regional information exchange.
Factors Associated with Preferred Place of Care and Death in Patients with Parkinson’s Disease: A Cross-Sectional Study
Authors: Pedrosa Anna J. , Feldmann Sarah , Klippel Jan , Volberg Christian , Weck Christiane , Lorenzl Stefan , Pedrosa David J.
Published: March 2024

Background:

A significant proportion of people with Parkinson’s disease (PwPD) die in hospital settings. Although one could presume that most PwPD would favor being cared for and die at home, there is currently no evidence to support this assumption.

Objective:

We aimed at exploring PwPD’s preferences for place of end-of-life care and place of death, along with associated factors.

Methods:

A cross-sectional study was conducted to investigate PwPD’s end-of life wishes regarding their preferred place of care and preferred place of death. Using different approaches within a generalized linear model framework, we additionally explored factors possibly associated with preferences for home care and home death.

Results:

Although most PwPD wished to be cared for and die at home, about one-third reported feeling indifferent about their place of death. Preferred home care was associated with the preference for home death. Furthermore, a preference for dying at home was more likely among PwPD’s with informal care support and spiritual/religious affiliation, but less likely if they preferred institutional care towards the end of life.

Conclusions:

The variation in responses regarding the preferred place of care and place of death highlights the need to distinguish between the concepts when discussing end-of-life care. However, it is worth noting that the majority of PwPD preferred care and death at home. The factors identified in relation to preferred place of care and death provide an initial understanding of PwPD decision-making, but call for further research to confirm our findings, explore causality and identify additional influencing factors.
The association of microRNAs in the development of retinopathy of prematurity
Authors: Ovali F. , Hakbilen M. , Akalin I. , Çelik G. , Yildirim S.
Published: March 2024

INTRODUCTION: Retinopathy of prematurity (ROP) is one of the main reasons of preventable childhood blindness. In the development of ROP, MicroRNAs may be effective in the balance of factors that inhibit and activate angiogenic factors. We aimed to determine the changes in the blood levels of miR-146a, miR-143, miR-210, miR-21, miR-126, miR-211, miR-221, miR-106 and let 7f and to investigate their association with ROP. We hypothesed that the level of these miRNAs changed significantly in ROP cases. MATERIALS AND METHODS: This observational study was conducted prospectively in preterm infants with ROP. Serum levels of 8 miRNAs were measured. The relationship between disease stage and progression with miRNA gene expression was analysed. Preterm infants without ROP were taken as the control group. RESULTS: 47 patients with ROP and 14 controls, were included in the study. In the ROP group, miR-210, miR-146a, miR-21 were statistically significantly lower. In the ROP group the expression level of miR-143 was insignificantly lower, miRNA-221 was insignificantly higher, and miR-106, miR-126 and let 7f were variable. CONCLUSION: It was observed that miR-210, miR-146a, miR-21 and miR-143 were significantly lower in patients with ROP compared to the control group. However, no association could be established between the type of miRNA and stage of ROP. These miRNAs may be used as adjunctive biomarkers for diagnosis of ROP.

BACKGROUND: Individuals with moderate to severe traumatic brain injury (msTBI) have reported a lack of motivation, lack of time, and fatigue as perceived barriers to exercise. OBJECTIVE: To evaluate the effects of an exercise program on self-reported health-related symptoms and quality of life in persons 45-years and older with msTBI. METHODS: Post-hoc analysis of a prospective community-based 12-week exercise program of 20 adults, age 45–80 years, with msTBI. Ten were in aerobic exercise training (AET) program and 10 in a stretching and toning (SAT) program. The AET group was instructed to exercise based on their estimated maximal heart rate (HR) for 150 minutes weekly. The SAT group was to stretch for the same target time without significantly increasing HR or level of exertion. Outcome measures were Traumatic Brain Injury Quality of Life (TBI-QOL) for global, cognitive, emotional, and social health, Patient Health Questionnaire-9 (PHQ-9) for depressive symptoms, and Pittsburgh Sleep Quality Index (PSQI) for sleep quality. RESULTS: AET was associated with improved self-reported cognitive health and sleep compared to SAT. Moderate to large, positive effect sizes were also observed in the AET group in the QOL categories of global, emotional, and social health, and depressive symptoms. CONCLUSIONS: This study offers preliminary evidence that AET may improve health-related QOL, especially for cognition and sleep, in middle-aged and older adults with msTBI.

BACKGROUND: Many authors have emphasized the need for individualized treatments in rehabilitation, but no tailored robotic rehabilitation protocol for stroke patients has been established yet. OBJECTIVE: To evaluate the effectiveness of a robot-mediated upper limb rehabilitation protocol based on clinical assessment for customized treatment of stroke patients. METHODS: Clinical data from 81 patients with subacute stroke, undergoing an upper limb robot-mediated rehabilitation, were analyzed retrospectively. 49 patients were treated using a customized robotic protocol (experimental group, EG) based on a clinically guided flowchart, while 32 were treated without it (control group, CG). Fugl-Meyer Assessment for Upper Extremity (FMA-UE), Motricity Index (MI), modified Barthel Index (mBI) and Numerical Rating Scale (NRS) measured before (T0) and after (T1) rehabilitation intervention were used as clinical outcomes. RESULTS: There was statistically significant improvement in both groups in terms of FMA-UE, MI, and mBI, while no change in NRS. Intergroup analysis showed significantly greater improvement of the FMA-UE (P = 0.002) and MI (P < 0.001) in the EG, compared with the CG. CONCLUSION: The implementation of our robotic protocol for customized treatment of stroke patients yielded greater recovery in upper limb motor function and strength over robotic treatment without a defined protocol.
Applying RFID and NLP for efficient warehouse picking
Authors: Xu Man , Wang Yunze , Xing Dan
Published: March 2024

This paper proposes an intelligent warehouse-picking approach using radio frequency identification (RFID) indoor positioning and natural language processing (NLP) speech recognition. A forward maximum matching algorithm segments speech into domain terminology. Location was estimated by RFID signal strengths between reference tags and pickers. Simulation results demonstrated a 50% reduction in segmentation runtime versus conventional methods. Speech recognition accuracy reached 90–95%, improving by 23% over baseline. Positioning accuracy also increased substantially. The techniques can reduce picking errors and costs. Further work should evaluate performance in real-world environments.

BACKGROUND: The upright head roll test (UHRT) is a recently introduced diagnostic maneuver for lateral semicircular canal benign paroxysmal positional vertigo (LSC-BPPV). OBJECTIVE: This study aimed to evaluate the reliability and validity of the UHRT. METHODS: Two separate studies were conducted. Study 1 analyzed 827 results of videonystagmography (VNG) to assess UHRT reliability, and Study 2 analyzed 130 LSC-BPPV cases to evaluate UHRT validity. RESULTS: The inter-test reliability between UHRT and the supine head roll test (SHRT) showed substantial agreement (Cohen’s kappa = 0.753) in direction-changing positional nystagmus (DCPN) and almost perfect agreement (Cohen’s kappa = 0.836) in distinguishing the direction of DCPN. The validity assessment of UHRT showed high accuracy in diagnosing LSC-BPPV (80.0%) and in differentiating the variant types (74.6%). UHRT was highly accurate in diagnosing the canalolithiasis type in LSC-BPPV patients (Cohen’s kappa = 0.835); however, it showed only moderate accuracy in diagnosing the cupulolithiasis type (Cohen’s kappa = 0.415). The intensity of nystagmus in UHRT was relatively weaker than that in SHRT (P < 0.05). CONCLUSION: UHRT is a reliable test for diagnosing LSC-BPPV and distinguishing subtypes. However, UHRT has a limitation in discriminating the affected side owing to a weaker intensity of nystagmus than SHRT.

BACKGROUND: Sexually Transmitted Infections (STIs), such as Human Immunodeficiency Virus (HIV) transmitted by biological, socioeconomic and cultural factors that increase the vulnerability of certain population groups such as civil construction workers. OBJECTIVE: To evaluate the knowledge of workers in the construction industry about infection by HIV and associated factors. METHODS: A cross-sectional, analytical study was conducted, including 381 construction workers, in the cities of João Pessoa, Cabedelo, and Santa Rita, in the State of Paraíba, Brazil, performed through interviews, using a data collection instrument with social demographic variables and the HIV Knowledge Questionnaire. Data were analyzed using descriptive measures, and for comparison between the categories the Kruskal-Wallis test was used, with margin of error of 5%. RESULTS: A predominance of male workers was observed (97.4%) among 381 workers; aged 30-39 (34.1%); married (81.4%); with up to eight years of education (66.6%); family income of up to 2x the minimum wage (52.8%) and coming from the country (43.8%). The average of correct responses was 63.3%, with higher indices (70.0%) related to transmission and forms of prevention. There were higher percentages of hits among those who had studied for 12 years or more. Workers from the capital of Paraíba presented a higher number of correct responses (67.44%). CONCLUSIONS: There is a low index of knowledge of construction workers about HIV, highlighting their consequent vulnerability to acquiring this infection.

BACKGROUND: As a reflection of the health emergency caused by COVID-19, many countries adopted guidelines, which included activity restrictions. As a result, some companies maintained their activities with on-site work and telework. OBJECTIVE: Analyzing the morbidity and mortality profile due to COVID-19 of workers in telework and on-site work in an oil and gas company. METHODS: Cross-sectional, quantitative, and analytical study that included 8,394 workers diagnosed with COVID-19 at an oil and gas company in Brazil, from June 2020 to June 2021. The company’s Surveillance Program database was used as an information source. RESULTS: The total prevalence of cases was 21.7%. For teleworking and face-to-face workers, they were 20.7% and 23.3%, respectively. There was a predominance of women (19.7%), white ethnicity/colour (64.7%), higher level position (52.6%), age group over 40 years (36.7%), married (53, 8%), working at the company for a period that ranges from 7 to 10 years (17%), administrative activity (68.5%), and a higher number of symptomatic workers and deaths in telework compared to on-site work. CONCLUSIONS: The results suggest that testing is important to refrain the virus spread in the company’s work environments, as it allowed asymptomatic workers to be diagnosed with COVID-19. The study suggested that on-site work was not a transmission facilitator in the occupational environment, which points out the importance of preventive measures in the workplace and the adoption of remote work for the largest possible number of workers to improve the safety of employees, workers who remained in the on-site work modality.
Which interventions are used in the rehabilitation, return, and stay at work process of aging workers having suffered an occupational injury? A scoping review
Authors: Audet Jessika , Lecours Alexandra
Published: March 2024

BACKGROUND: Considering current labour shortages, the recent increase in the number of aging workers in the labour market is deemed economically beneficial. However, due to specific characteristics (e.g. biological, generational), aging workers take longer to recover and return to work after an occupational injury. Yet, few studies have examined the rehabilitation, return, and stay at work process of aging workers and current knowledge makes it difficult for stakeholders to identify which interventions to use with this specific population. OBJECTIVE: This study aimed to describe which interventions are used in the rehabilitation, return, and stay at work process of aging workers having suffered an occupational injury. METHODS: We conducted a five-step scoping review. Five databases were used for the literature search. A qualitative analysis of the retained manuscripts was conducted. RESULTS: Our analysis led to the extraction of information from seven manuscripts that concern the rehabilitation, return, and stay at work process of aging workers who suffered an occupational injury exclusively. We identified 19 interventions (e.g. work capacity development, work task modifications, permanent part-time work, and alternative roles) and were described according to the different phases of the Cycle of Work Disability Prevention (CWDP). CONCLUSIONS: This study offers informative, non-prescriptive, and operational interventions useful for stakeholders who support aging workers. Furthermore, it is a knowledge base to develop future projects that promote the rehabilitation, return, and stay at work process of aging workers.

Published: March 2024

The dynamic behavior of a three-layer cylindrical structure of normal elliptical cross-section with a discrete polymer filler under the action of an internal non-stationary load was studied. Finite element models of the structure were created and deformations and normal stresses of its bearing layers were calculated. Variants of structures without polymer aggregate and with aggregate of different stiffness, reinforced with ribs, were considered. A comparative analysis of the deformations and stresses of the bearing layers at the ratio of the modulus of elasticity of the material of the bearing layers and the aggregate E1.2/Et=500 and E1.2/Et=50 is given. Finite elements of the Solid and Laminate types are used in the finite-element models. The calculations were carried out by the software and calculation complex Nastran using the direct transient dynamic process algorithm.

The relevance of the problem of transforming the clip-based thinking of higher education students in the conditions of teaching construction mechanics and its solution taking into account the didactic capabilities of educational and digital technologies is undeniable in view of the dynamics of the growth of the volume of educational information, which requires the subjects of the educational process to flexibly adapt scientific approaches, teaching technologies , ways of thinking to modern educational needs. It was determined that clip thinking, which is characterized by speed and superficial consideration of information, lack of attention and its concentration, fragmentation and mosaicism of the world picture, loss of desire for knowledge, reduced need and ability for productive activity, can be both an advantage and a disadvantage in the conditions of digital era, modern system requirements for the training of professionals with a formed system of value orientations, innovative thinking, a culture of cognitive activity. It was established that the essence of the transformation of clip thinking of higher education students in the context of teaching construction mechanics is the integration of educational innovations with the aim of improving the quality of learning and teaching, developing students' critical thinking, and changes in the ways of perceiving and processing information. It was found that didactic mechanisms for the transformation of clip thinking - effective use of data analytics, interactive educational platforms, data visualization, joint platforms and exchange of opinions, automation of processes for data collection and processing, stimulation of critical thinking - contribute to the balanced use of educational tools to improve the perception of information , the development of cognitive competence and contribute to the creation of an educational environment that meets the needs of today. It was concluded that the properties of "clip thinking" can be transformed under the condition of the appropriate construction of the organization of the study of construction mechanics in the direction of the logical presentation of educational material; compliance of training with practical goals; implementation of learning technologies aimed at educational interaction; ensuring an individual approach to the organization of students' educational and cognitive activities.
