Возраст и риски производственного травматизма у категорий личного состава Федеральной противопожарной службы МЧС России

The objective of the article is to detect the interconnection between the age and professional experience of the personnel of the Federal Firefighting Service of the EMERCOM of Russia and the risks of industrial injuries. Reports on industrial injuries among the categories (operational, technical, maintenance, and administrative personnel) of personnel of the Federal Firefighting Service of the EMERCOM of Russia have been studied. The average weighted expected risk of injuries for 10 thousand people was calculated. The average age of the injured personnel of the Federal Firefighting Service of the EMERCOM of Russia is (36.2  0.3) years with working experience of (10.2  0.3) years. The average weighted expected risk of body area injuries among firefighters in 2012–2021 is (11.96  0.89)·10–4 injuries/(persons·year). The analysis has demonstrated the decrease in injury rate among the personnel of the Federal Firefighting Service of the EMERCOM of Russia at large. The interconnection between the injury rate, age, and professional experience among the personnel’s categories of the service have certain similarities and differences affected by a number of factors that sometimes can be multidirectional: the risk of injuries is higher for younger and unexperienced personnel who are, consequently, undertrained and lack expertise, knowledge, and competence; at the same time, they demonstrate high confidence in their possibilities, which often causes irresponsible attitude towards the labor protection requirements; along with the increase in professional experience, the practical experience and the command of safe working methods increase among the personnel, which reduces the risk of injuries; more experienced firefighters are more often involved in complex and important operations during fires, which increases the risk of injuries; senior and unexperienced employees of fire protection divisions experience particular difficulties when obtaining practical skills and learn safe working methods of firefighting, as compared to the younger employees; in addition, physical and psychical operability declines with age as the human body cannot respond promptly to changes in difficult situations and find solutions to overcome them, which increases the risk of injuries; along with the increase in professional experience, certain career growth is registered for many employees; hence, when performing higher-level posts, the personnel is less often exposed to hazardous factors of fire, which reduces the risk of injuries. At the same time, the phenomenon of the increasing risk of injuries among experienced firefighters of pre-retirement age must be marked specifically.

Validation Model of Water Crisis Management Policy in Iran

The present study is applied in nature and employs a quantitative, descriptive cross-sectional survey method for data collection. The statistical population comprises all experts and active managers associated with the water industry (national water resources management). According to the latest human resources statistics in national water resources management, the population includes 20,000 technical, engineering, and managerial personnel across the country. The sample size for this study was calculated using the Morgan table, resulting in a sample of 391 respondents. The research instrument consists of a 47-item questionnaire developed by Mahdavi Far et al. (2024). The reliability of the research instrument was assessed using Cronbach's alpha, yielding a value of 0.724. The findings from the study indicate that the highest path coefficient pertains to the relationship between strategies and outcomes, with a path coefficient of 0.947. The second highest is the relationship between causal conditions and the core category, with a path coefficient of 0.923. The relationship between contextual conditions and strategies follows, with a path coefficient of 0.879. The fourth highest path coefficient is between intervening conditions and strategies at 0.851, and finally, the core category and strategies have a path coefficient of 0.844. The results of the research demonstrate that causal conditions have a significant positive effect on the core phenomenon (β = 0.923, t = 49.568, p < 0.0001). Therefore, an increase in causal conditions leads to an increase in the core phenomenon. Additionally, contextual factors significantly and positively affect strategies (β = 0.879, t = 47.632, p < 0.001), suggesting that an increase in contextual factors leads to an enhancement in strategies. Intervening conditions also have a significant positive effect on strategies (β = 0.851, t = 41.937, p < 0.001), indicating that these conditions contribute to the reduction in strategies. Furthermore, the core phenomenon significantly and positively influences strategies (β = 0.844, t = 45.177, p < 0.001), suggesting that an increase in the core phenomenon enhances strategies. Finally, strategies significantly and positively affect outcomes or results (β = 0.947, t = 53.941, p < 0.001), indicating that an increase in strategies leads to improved outcomes or results.

Risk factors for anaemia among pregnant women: A cross-sectional study in Upper East Region, Ghana.

Anaemia in pregnancy (AIP) is a public health concern due to its devastating effects on women and their unborn babies, resulting in increased maternal and neonatal deaths in developing countries. Despite several Ghanaian health policies to combat AIP, AIP is still on the rise. It becomes imperative to identify geographic-specific factors for developing appropriate interventions for the management of AIP. However, Kassena Nankana West District (KNWD) in the Upper East Region of Ghana lacks a study on anaemia risk factors, therefore, this study estimated the prevalence and risk factors for anaemia among pregnant women in the district. A cross-sectional study was conducted from February to March 2023 in the KNWD. Approximately 376 pregnant women in their third trimester were randomly selected from 10 health facilities by utilizing the antenatal register as the sampling frame. Anthropometric, obstetric, sociodemographic, and health facility resource characteristics were collected using structured questionnaires and from antenatal records. Mixed-effect logistic regression was used to identify independent factors of anaemia at 95% confidence interval. Prevalence of AIP was 53.9% (95%CI:48.5%-58.8%). Mild, moderate, and severe anaemia prevalence was 16.9%, 35.3%, and 1.7% respectively. Malaria infection during pregnancy (aOR = 1.64; 95%CI:1.03-2.62) and accessing health facilities without trained laboratory personnel (aOR = 5.49; 95%CI:1.67-18.00) were associated with increased odds of AIP. Belonging to the major ethnic group (aOR = 0.52; 95%CI:0.28-0.85), accessing health facilities without laboratory services (aOR = 0.14; 95%CI:0.04-0.47), and accessing health facilities without sulphadoxine-pyrimethamine drugs (aOR = 0.22; 95%CI:0.06-0.86) in KNWD were also associated with decreased odds of AIP. KNWD has a severe burden of AIP. Maternal and health facility-related factors were associated with AIP in the district. These factors are preventable. Therefore, the provision of functional laboratory services with dedicated technical personnel, regular supply of sulphadoxine-pyrimethamine drugs to the health facilities, and enhanced community education on malaria prevention are recommended for anaemia control in the district.

Fundamentals of forecasting explosive gas accumulation formation in working areas of coal mines

This article presents a methodological approach to solving the problem of predicting local methane accumulations in order to prevent occupational injuries resulting from explosions of methane-air mixtures. On the basis of the analysis of accidents that occurred in coal mines and industrial injuries of miners (mine workers) it is established that the leading role belongs to explosions of methane-air mixtures. The method/methodology considered in the article is based on a comprehensive analysis, first of all, of both mining and geological and other influencing factors and conditions of operating mines of the Pechersk coal basin, as well as aerogas-dynamic processes of mass transfer of air flows in mine workings. The assumption about influence of mining equipment on the process of formation of methane accumulation sites is made. The algorithm of consecutive actions of managerial engineering and technical personnel to reduce industrial injuries is proposed. The developed algorithm implies the use of applied software for modelling aerogas-dynamic processes in the mining excavation operating region. FlowVision and ANSYS Fluent application software packages were selected to determine the methane accumulation locations based on the analysis of existing application programmes.

HIF-1α: a potential biomarker in obstructive sleep apnea

Obstructive sleep apnea (OSA) is a common breathing disorder characterized by repeated obstruction of the upper airway during sleep. Although polysomnography (PSG) is the widely used method for the diagnosis of OSA, it is a time-consuming and expensive method. Because it requires at least 1 night stay in the hospital and technical personnel are needed. Therefore, it has been focused on biomarkers that can be easily detected in blood for the diagnosis of OSA. Some studies have highlighted the relationship between OSA and cancer in humans, and HIF-1 is an important regulator in this process. KDM3A is a histone demethylase that increases hypoxic gene expression. We aimed to evaluate whether the expression levels of HIF-1α and KDM3A genes could be useful predictors in patients with OSA. Our study included 50 patients with OSA and 50 healthy controls. qRT-PCR was used to detect mRNA levels of HIF-1α, KDM3A, and epithelial-mesenchymal transition (EMT) genes in the leukocyte samples. The expression level of the HIF-1α gene was found significantly higher in the OSA group compared to the controls, and no statistically significant difference was detected in the expression levels of the KDM3A and EMT genes.

What determines behavioural intention in health services? A four-stage loyalty model

PurposeThis study aims to deal with the paucity of studies in the stages of the development of loyalty behaviour of customers in the healthcare context by incorporating three crucial service quality dimensions (physical environment, personnel quality and technical quality) and also investigating trust and commitment as mediating factors.Design/methodology/approachSurvey data were obtained from 420 respondents admitted to government hospitals in Kerala employing a convenience sampling method. The formulated hypotheses were tested using partial least square structural equation modelling.FindingsResults indicate that patient satisfaction, trust and commitment can create favourable behavioural intentions amongst patients. When patients reveal higher trust, they are more inclined to value healthcare services and willing to commit to a long-term relationship, resulting in increased patient loyalty.Practical implicationsOrganisational efforts should improve trust and commitment and build a good relationship between service providers and patients. Efforts should be taken to raise the standard of technical and personnel aspects, and a focus on physical infrastructure should also be considered to build a favourable behavioural intention to revisit and positive referrals.Originality/valueThis is the first empirical study to analyse technical quality, personnel quality and physical environment along with the mediating effect of trust, and commitment in a four-stage loyalty development model in the healthcare context of Kerala, India.

Simulation and analysis of hydraulic transition process based on mechanical hydraulics.

With the scarcity of water resources in various regions, the pressure on water supply projects is also increasing, which has led to a sharp increase in the water hammer effect in water supply pump projects. In response to this issue, the study proposes to apply a unidirectional pressure regulating tower based on mechanical hydraulic technology to water hammer protection in water supply pumps. In addition, the study also optimizes the calculation method of water hammer and designs one simulation software, which is used to simulate and analyze the proposed water hammer protection measures. The study first determines through simulation software that the optimal initial water level of the unidirectional pressure regulating tower is 2m and the optimal diameter of the make-up water pipe is 600 mm. Afterwards, simulation analysis is conducted on different water hammer protection measures, and it is found that the maximum pressure of the water hammer under the proposed protection measures is the lowest, at 14.8m, which was lower than the comparison measures. In addition, according to expert ratings, the average protective effect rating of protective measure 1 by relevant technical personnel is 9.4 points, which is better than the comparative measure. The above results indicate that through the simulation analysis of hydraulic transition process based on mechanical hydraulics, it can be found that the water hammer protection measures proposed in the study have good protective functions and can effectively reduce the water hammer effect in water supply engineering.

The Influence of Equity Incentive and its Concentration Degree on Enterprise Investment Efficiency

As an important part of China's modern industrial system, high-tech industry has long-term inefficient investment problems due to the characteristics of high investment demand, high risk and long cycle. As an incentive and constraint mechanism based on the principal-agent theory, equity incentive can effectively reduce the agency cost and improve the investment efficiency of enterprises. Based on the different perspective of equity incentive between senior executives and core technical personnel, this paper takes the sample of equity incentive in 2018-2022 to test the impact of equity incentive on the investment efficiency of enterprises. The results show that equity incentive can effectively improve the investment efficiency, alleviate the investment shortage and restrain the excessive investment; equity concentration plays a negative effect on the relationship between equity incentive and enterprise investment efficiency; compared with executive equity incentives, core technical personnel equity incentives have a more significant effect on improving investment efficiency, Therefore, enterprises should pay attention to improving the level of equity incentive; focus on the influence of equity structure on the utility of equity incentive and prevent excessive equity concentration; when designing equity incentive plans, focus on incentivizing core technical personnel.

Environmental Problems in Logistics Engineering from the Perspective of Engineering Ethics

At present, our country is facing a new round of scientific and technological revolution and a new situation of industrial transformation. With the emergence of modern major projects, its impact on the environment and the future of mankind is very significant. Engineering ethics is the professional ethics of engineering and technical personnel. Engineering ethics can guide, regulate, and develop the professional ethics of engineers and the construction of engineering projects. Therefore, the study of engineering ethics has long-term and important significance. Logistics activities run through the four major fields of production, circulation, consumption and national defense, and are the blood of my country's economy. Engineering ethics is a discipline that studies these problems in depth and seeks for their emergence and solutions. This article will analyze the engineering ethics dilemma of each link of logistics activities from warehousing, transportation, packaging, circulation processing, and loading and unloading, and conduct practical thinking on these issues, and put forward insights and improvement methods.

Analysis of the motivation and impact of the implementation of the employee stock ownership plan

Equity incentive can be divided into executive equity incentive (Executive Stock Option) and employee equity incentive (Employee Stock Option). Employees here refer to the intermediate managers, core technical personnel and other employees except for the senior executives of the company. The ESOP is a mechanism by which the employees of the company share the ownership of the company by holding the stock or options of the company. From the perspective of the implementation of the employee stock ownership plan motivation, its main theoretical basis can be divided into three categories, respectively is incentive theory (incentive theory, reduce agent costs, attract, retain quality employees and limited to financing constraints, reduce cash pressure), signal theory (undervalued company more inclined to internal equity incentives, let investors aware that the current company price relative to its internal value deviation) and major shareholders self-interest theory. From the theoretical point of view, this paper discusses the possible motives and results of domestic listed companies to launch the stock ownership plan, in order to provide theoretical support for small and medium investors to rationally understand the employee stock ownership plan, and provide regulatory suggestions to the regulatory authorities to be vigilant about the self-interest behavior of major shareholders.

Immune response status and development of streptococcus pneumoniae carriage as health risk factors for workers engaged in coke production and basic oxygen steelmaking

Occupational hazards affect immunological reactivity and increase the risk of infection with respiratory pathogens. The purpose of our work was to study the mechanisms and causes of developing carriage of streptococci possessing genetic determinants of resistance to antibiotics as health risk factors for workers engaged in coke production and basic oxygen steelmaking. We examined 136 workers of a ferrous metals industry and compared the prevalence of the carriage of Streptococcus pneumoniae, Streptococcus spp. and macrolide resistance genes (Mef, ErmB) in those engaged in coke production and basic oxygen steelmaking. We also collated the results of immunological examination of the carriers and non-carriers of S. pneumoniae. The control cohort was formed of engineering and technical personnel. We established that, compared with the controls, Streptococcus pneumoniae was a more frequent finding in the workers engaged in coke production and basic oxygen steelmaking (p ˂ 0.05). The cycle threshold value of Streptococcus spp. in them was also statistically higher. The Mef gene was more abundant in the steelmakers, including those carrying Streptococcus pneumoniae (p ˂ 0.05), and a change in immunological reactivity was detected in the cases carrying Streptococcus pneumoniae. In those engaged in basic oxygen steelmaking, significant changes were detected at the cellular level expressed by a reduced absolute number of mature T-lymphocytes (CD3+), T-helpers (CD4+), and T-suppressor/cytotoxic cells (CD8+) (p ≤ 0.05). At the humoral level, both the relative and absolute number of B-lymphocytes (CD19+) and the level of IgM were reduced, while that of IgG was, on the opposite, increased (p ≤ 0.05). In the coke plant workers carrying Streptococcus pneumoniae, the level of IgG was significantly higher than the control and reference values. We conclude that Streptococcus pneumoniae carriage in the steelmakers as a health risk factor was accompanied by a change in immunological reactivity and higher abundance of the Mef gene compared to the controls while in the coke production workers the related differences were detected only in the IgG level.

A MULTICRITERIA METHOD TO IDENTIFY AND RANK IEQ CRITICALITIES: MEASUREMENTS AND APPLICATIONS FOR AN EXISTING SCHOOL BUILDING

This study proposes a method to obtain a ranking of the critical issues related to Indoor Environmental Quality (IEQ)in existing school buildings . A multi-criteria method for a comprehensive evaluation of IEQ in school buildings is described and discussed. The method includes data collection, field measurements, and subjective investigations. The novelty of the study does not lie in the single stages of which the method is composed (for example in the phase involving field measurements, there are consolidated procedures in the technical and scientific literature to conduct them), but rather in the collection and rationalization of a complete and articulated assessment process that can guide the technicians and managers in the decision making. To show the whole proposed evaluation method, the case study of the university classrooms of the School of Engineering of Pisa was studied. From the application of the evaluation method to the case study, a rank of the IEQ critical issues observed and a rank of the most IEQ critical environments was therefore obtained. The study also focused on the impact of weighting schemes of the IEQ assessment results. Then the results of the case study were discussed by evaluating the impact of alternative weighing schemes present in the scientific literature. The discussion shows that to identify the most critical environmental factors, the choice of the weighting scheme is extremely important although the greatest weight does not always correspond to the most critical environmental factor. The presented results can interest not only technical personnel involved in IEQ assessments and interventions for its improvement, but also researchers investigating IEQ that intend to compare methodologies and weighting schemes.

Automated Machine Learning Analysis of Patients With Chronic Skin Disease Using a Medical Smartphone App: Retrospective Study.

Rapid digitalization in health care has led to the adoption of digital technologies; however, limited trust in internet-based health decisions and the need for technical personnel hinder the use of smartphones and machine learning applications. To address this, automated machine learning (AutoML) is a promising tool that can empower health care professionals to enhance the effectiveness of mobile health apps. We used AutoML to analyze data from clinical studies involving patients with chronic hand and/or foot eczema or psoriasis vulgaris who used a smartphone monitoring app. The analysis focused on itching, pain, Dermatology Life Quality Index (DLQI) development, and app use. After extensive data set preparation, which consisted of combining 3 primary data sets by extracting common features and by computing new features, a new pseudonymized secondary data set with a total of 368 patients was created. Next, multiple machine learning classification models were built during AutoML processing, with the most accurate models ultimately selected for further data set analysis. Itching development for 6 months was accurately modeled using the light gradient boosted trees classifier model (log loss: 0.9302 for validation, 1.0193 for cross-validation, and 0.9167 for holdout). Pain development for 6 months was assessed using the random forest classifier model (log loss: 1.1799 for validation, 1.1561 for cross-validation, and 1.0976 for holdout). Then, the random forest classifier model (log loss: 1.3670 for validation, 1.4354 for cross-validation, and 1.3974 for holdout) was used again to estimate the DLQI development for 6 months. Finally, app use was analyzed using an elastic net blender model (area under the curve: 0.6567 for validation, 0.6207 for cross-validation, and 0.7232 for holdout). Influential feature correlations were identified, including BMI, age, disease activity, DLQI, and Hospital Anxiety and Depression Scale-Anxiety scores at follow-up. App use increased with BMI >35, was less common in patients aged >47 years and those aged 23 to 31 years, and was more common in those with higher disease activity. A Hospital Anxiety and Depression Scale-Anxiety score >8 had a slightly positive effect on app use. This study provides valuable insights into the relationship between data characteristics and targeted outcomes in patients with chronic eczema or psoriasis, highlighting the potential of smartphone and AutoML techniques in improving chronic disease management and patient care.
