Zero capital depreciation point for Ukrainian commercial organizations
Authors:   Volodymyr Dahl East Ukrainian National University, Luhansk, Ukraine, et al. Morhachov
Published: July 2022

The problem of capital shortage for Ukrainian commercial organizations has been clarified, which makes the theoretical and methodological provisions of its increase and preservation relevant. Insufficient capital for investment processes is a significant obstacle to the development of most business entities in Ukraine. The analysis of recent research and publications on the topic of the work showed that the issues of tools for estimating the point of zero depreciation of equity for Ukrainian commercial organizations still have room for improvement. The aim of the work is to substantiate the tools for estimating the point of zero depreciation of equity for Ukrainian commercial organizations. The main source of compensation for the depreciation of equity due to inflation and devaluation of the national currency is the profit of the organization. The return on equity is a relative indicator that characterizes the degree of appropriate compensation. The tools for estimating the point of zero depreciation of equity should be considered as such a value of return on equity, which compensates for its depreciation due to various factors. Due to the need to divide the factors of impairment of equity into two groups, the use of two types of zero depreciation points is justified: Cash and alternative. As a widely used alternative to the use of equity for the average investor, investing in shares of ETFs is justified, completely repeating the US stock index S and P-500 with a long-term efficiency of 9.5% per annum in US dollars. Approbation of the presented valuation tools allowed us to determine that for Ukrainian commercial organizations the alternative point of zero depreciation of equity is 26.9% and cash-17.6%. It is specified that the average enterprise in the country does not reach the level of even a cash point. There are a limited number of economic activities in the country where the cash point of zero depreciation of equity is exceeded. Reducing inflation to 7-6% per year along with the stabilization of the national currency will bring a significant number of economic activities in the country to the level of reaching the cash point of depreciation of equity.

La producción comercial de semillas germinadas de palma africana (Elaeis guineensis Jacq) tarda 150 días, dando lugar al desarrollo de infecciones causadas por patógenos. Con el objetivo de disminuir el tiempo de producción de semillas germinadas de palma aceitera africana y preservar su estado fitosanitario, se evaluaron cuatro factores: i) tres niveles de imbibición antes de ingresar a calentamiento, ii) dos periodos de calentamiento, iii) dos niveles de imbibición antes de ingresar a cuartos de germinación y iv) dos inductores: ácido salicílico (AS) y ácido β aminobutírico (BABA) en dosis de 1 mM y 2,5 mM, respectivamente; como resultado se obtuvo un total de 24 tratamientos más un testigo. Se evaluaron 30 semillas por tratamiento y por repetición procedentes de un mismo racimo tipo Dura, con cero días de almacenamiento. Se utilizó un diseño completamente al azar con arreglo factorial +1, asistido por la prueba de Tukey al 5 %. Los resultados mostraron que las semillas que estuvieron durante la primera imbibición 6 días en agua y 2 días en BABA o en AS, más 20 días de calentamiento, presentaron en 82 días el mayor porcentaje de germinación óptima (34,44 % y 23,89 %, respectivamente), y el tratamiento que estuvo durante la primera imbibición 6 días en agua y 2 días en BABA, más 20 días de calentamiento, logró el mayor porcentaje de germinación óptima (40 %). El testigo presentó mayor incidencia de enfermedades (79 %) con respecto a los factores (16 %). Los hallazgos del estudio podrían usarse para disminuir el tiempo de germinación de semillas y los daños provocados por patógenos.
Integrating Natural Language Processing and Interpretive Thematic Analyses to Gain Human-Centered Design Insights on HIV Mobile Health: Proof-of-Concept Analysis
Authors: Skeen Simone J , Jones Stephen Scott , Cruse Carolyn Marie , Horvath Keith J
Published: July 2022

Background

HIV mobile health (mHealth) interventions often incorporate interactive peer-to-peer features. The user-generated content (UGC) created by these features can offer valuable design insights by revealing what topics and life events are most salient for participants, which can serve as targets for subsequent interventions. However, unstructured, textual UGC can be difficult to analyze. Interpretive thematic analyses can preserve rich narratives and latent themes but are labor-intensive and therefore scale poorly. Natural language processing (NLP) methods scale more readily but often produce only coarse descriptive results. Recent calls to advance the field have emphasized the untapped potential of combined NLP and qualitative analyses toward advancing user attunement in next-generation mHealth.

Objective

In this proof-of-concept analysis, we gain human-centered design insights by applying hybrid consecutive NLP-qualitative methods to UGC from an HIV mHealth forum.

Methods

UGC was extracted from Thrive With Me, a web app intervention for men living with HIV that includes an unstructured peer-to-peer support forum. In Python, topics were modeled by latent Dirichlet allocation. Rule-based sentiment analysis scored interactions by emotional valence. Using a novel ranking standard, the experientially richest and most emotionally polarized segments of UGC were condensed and then analyzed thematically in Dedoose. Design insights were then distilled from these themes.

Results

The refined topic model detected K=3 topics: A: disease coping; B: social adversities; C: salutations and check-ins. Strong intratopic themes included HIV medication adherence, survivorship, and relationship challenges. Negative UGC often involved strong negative reactions to external media events. Positive UGC often focused on gratitude for survival, well-being, and fellow users’ support.

Conclusions

With routinization, hybrid NLP-qualitative methods may be viable to rapidly characterize UGC in mHealth environments. Design principles point toward opportunities to align mHealth intervention features with the organically occurring uses captured in these analyses, for example, by foregrounding inspiring personal narratives and expressions of gratitude, or de-emphasizing anger-inducing media.
The Effects of Information Continuity and Interpersonal Continuity on Physician Services Online: Cross-sectional Study (Preprint)
Authors: Xuan Yan , Guo Chaojin , Lu Wei
Published: July 2022

BACKGROUND

Web-based medical services have become an effective supplement to traditional services in hospitals and an essential part of medical services. Studies have shown that web-based medical services are useful for shortening the delayed admission time and for enhancing the treatment effect from the service continuity perspective. However, the specific measures that patients and physicians should take to improve service continuity remain unknown.

OBJECTIVE

Based on the information richness theory and continuity of care, this study investigates the dynamic effects of information continuity and interpersonal continuity on physician services online.

METHODS

Data of 7200 patients with 360 physicians covering complete interaction records were collected from a professional web-based platform in China. Content analysis was performed to recognize matching patients and physicians, and least square regression analysis was performed to obtain all empirical results.

RESULTS

Empirical results showed that in the short term, information continuity (including offline experience, medical records, and detailed information) influences physicians’ web-based services, and their influences show heterogeneity. Moreover, if a patient’s online physician is the same physician who he/she has visited offline, we find that interpersonal continuity is important for service. In the long term, information continuity and interpersonal continuity positively improve service continuity by facilitating repeat purchases.

CONCLUSIONS

Overall, our findings not only shed new light on patient behavior online and cross-channel behavior but also provide practical insights into improving the continuity of care in online health communities.

Upper EXTremity Examination for Neuromuscular Diseases (U-EXTEND): A protocol for a feasibility study to explore the use of wearable sensors and ultrasound techniques to
develop novel measures for muscle function (Preprint)
Authors: Barnes Laura , Gutierrez Robert , McCrady Allison , Tolman Sarah , Boukhechba Mehdi , Blemker Silvia , Scharf Rebecca , Masterson Chelsea
Published: July 2022

BACKGROUND

Neuromuscular diseases, such as Spinal Muscular Atrophy (SMA) and Duchenne Muscular Dystrophy (DMD), may lead to loss of motor movements, respiratory failure, and early mortality in young children and adulthood. With novel treatments now available, new evaluation methods are needed to assess progress not currently captured with existing motor scale tests.

OBJECTIVE

With this feasibility study, our interdisciplinary team of investigators aims to develop a novel, multi-modal paradigm of measuring motor function in children with neuromuscular diseases that will revolutionize the way clinical trial endpoints are measured moving forward, therefore accelerating the pipeline of new treatments for childhood neuromuscular diseases. Through the Upper EXTremity Examination for Neuromuscular Diseases (U-EXTEND), we hypothesize that the novel objective measures of upper extremity muscle structure and function proposed here will be able to distinguish small changes and differences in function that are not measurable by current clinical metrics.

METHODS

U-EXTEND introduces a novel paradigm using concrete, quantitative measures to assess motor function in patients with SMA and DMD. Aim 1 will focus on the use of ultrasound techniques to study muscle size, quality, and function, specifically isolating the biceps and pronator muscles of the upper extremity to follow over time. To achieve this, clinical investigators will extract a set of measurements related to muscle structure, quality, and function using ultrasound imaging and handheld dynamometry. Aim 2 will leverage wearable wireless sensor technology to capture motion data as subjects perform activities of daily living. Measurement data will be examined and compared to a healthy cohort, while providing a motor function score.

RESULTS

U-EXTEND data collection began in January 2020, and we anticipate preliminary results will be available in Summer 2022.

CONCLUSIONS

U-EXTEND is poised to make a valuable contribution to the neuromuscular disease community, clinical trial design, ubiquitous computing technologies, and skeletal muscle ultrasound imaging. We are especially eager to explore the ability of U-EXTEND to support clinical outcomes, and to provide clarity in patient motor function ability in neuromuscular disorders, and extending to a wide variety of neuromotor challenges.

Authors: van Spaendonck Zita , Leeuwenburgh Koen Pieter , Dremmen Marjolein , van Schuppen Joost , Starreveld Daniëlle , Dierckx Bram , Legerstee Jeroen S
Published: July 2022

BACKGROUND

An MRI-procedure can cause preprocedural and periprocedural anxiety in children. Psychosocial interventions are used to prepare children for the procedure to alleviate anxiety, but these interventions are time- and cost consuming. Virtual Reality (VR) is a promising way to overcome these limitations in the preparation of children before an MRI-scan.

OBJECTIVE

The objective of this study is (1) to develop a virtual reality (VR) smartphone intervention to prepare children for an MRI-procedure at home; and (2) to examine the effect of the VR-intervention in a randomized controlled trial (RCT), in which the VR-intervention will be compared to care as usual (CAU).

METHODS

The VR-intervention provides a highly realistic and child friendly representation of an MRI-environment. In this RCT, 128 children (aged 6 to 14 years) undergoing an MRI-scan will be randomly allocated to the VR-intervention or the CAU. Children in the VR-intervention receive a login code for the VR app and are send cardboard VR glasses. The primary outcome is preprocedural anxiety (self-reported and as observed by parents). Secondary outcomes include periprocedural anxiety and parental anxiety.

RESULTS

The VR smartphone preparation app has been developed in 2020. The recruitment of participants is expected to be completed in December 2022.

CONCLUSIONS

The VR smartphone application is expected to significantly reduce pre- and periprocedural anxiety in pediatric patients undergoing an MRI-scan. The VR app offers a realistic and child friendly experience which can contribute to modern care. A smartphone version of the VR application has the advantage that children, and potentially their parents, can get habituated to the VR environment and noises, in their own home environment and can do this VR MRI preparation as often and as long as needed.

Authors: Albali Nawaf , Almudarra Sami , Al-Farsi Yahya , Alarifi Abdullah , Al Wahaibi Adil , Penttinen Pasi
Published: July 2022

BACKGROUND

Evaluating public health surveillance systems is important to ensure that events of public health importance are appropriately monitored. Evaluation studies based on the Centers for Disease Control and Prevention (CDC) guidelines have been used to appraise surveillance systems globally. Previous evaluation studies undertaken in member countries of the Gulf Cooperation Council (GCC) were limited to specific illnesses within a single nation.

OBJECTIVE

We aimed to evaluate public health surveillance systems in GCC countries using CDC guidelines and recommend necessary improvements to enhance these systems.

METHODS

The CDC guidelines were used for evaluating the surveillance systems in GCC countries. A total of 6 representatives from GCC countries were asked to rate 43 indicators across the systems’ level of usefulness, simplicity, flexibility, acceptability, sensitivity, predictive value positive, representativeness, data quality, stability, and timeliness. Descriptive data analysis and univariate linear regression analysis were performed.

RESULTS

All surveillance systems in the GCC covered communicable diseases, and approximately two-thirds (4/6, 67%, 95% CI 29.9%-90.3%) of them covered health care–associated infections. The mean global score was 147 (SD 13.27). The United Arab Emirates scored the highest in the global score with a rating of 167 (83.5%, 95% CI 77.7%-88.0%), and Oman obtained the highest scores for usefulness, simplicity, and flexibility. Strong correlations were observed between the global score and the level of usefulness, flexibility, acceptability, representativeness, and timeliness, and a negative correlation was observed between stability and timeliness score. Disease coverage was the most substantial predictor of the GCC surveillance global score.

CONCLUSIONS

GCC surveillance systems are performing optimally and have shown beneficial outcomes. GCC countries must use the lessons learned from the success of the systems of the United Arab Emirates and Oman. To maintain GCC surveillance systems so that they are viable and adaptable to future potential health risks, measures including centralized information exchange, deployment of emerging technologies, and system architecture reform are necessary.
Tracking Locomotion using Reinforcement Learning
Authors: Jadhav Rutuja
Published: July 2022

Abstract: This article presents the concept of reinforcement learning, which prepares a static direct approach for consistent control problems, and adjusts cutting-edge techniques for testing effectiveness in benchmark Mujoco locomotion tasks. This model was designed and developed to use the Mujoco Engine to track the movement of robotic structures and eliminate problems with assessment calculations using perceptron’s and random search algorithms. Here, the machine learning model is trained to make a series of decisions. The humanoid model is considered to be one of the most difficult and ongoing problems to solve by applying state-of-the-art RL technology. The field of machine learning has a great influence on the training model of the RL environment. Here we use random seed values to provide continuous input to achieve optimized results. The goal of this project is to use the Mujoco engine in a specific context to automatically determine the ideal behavior of the robot in an augmented reality environment. Enhanced random search was introduced to train linear guidelines for achieving the efficiency of Mujoco roaming tasks. The results of these models highlight the variability of the Mujoco benchmark task and lead to efficiently optimized rewards

Personality Evaluation through CV Analysis using Machine Learning Algorithm
Authors: Mali Suraj
Published: July 2022

Abstract: Human personality has played a vital role in an individual's life as well as in the development of an organization. One of the ways to judge human personality is by using standard questionnaires or by analyzing the Curriculum Vitae (CV). Traditionally, recruiters manually shortlist/filters a candidates CV as per their requirements. In this paper, we present a system that automates the eligibility check and aptitude evaluation of candidates in a recruitment process. To meet this need an online application is developed for the analysis of aptitude or personality test and candidate‟ CV. The system analysis professional eligibility based on the uploaded CV. The system employs a machine learning approach using TF-IDF Algorithm. The output of our system gives a decision for candidate recommendation. Further, the resulting scores help in evaluating the qualities in the candidates by analyzing the scores obtained in different areas. The graphical analysis of the performance of any candidate makes it easier to evaluate his/her personality and helpful in analyzing the CV properly. Thus, the system provides a helping hand for the recruitment process so that the candidates CV will be shortlisted and the fair decision will be made
Leucodistrofia metacromática del adulto: reporte de caso
Authors: Beltrán Carrascal Elkin José , López Brokate Laura , Hernández González María Isabel , Espitia De La Hoz Juan José , Domínguez Guzmán David Andrés
Published: July 2022

INTRODUCCIÓN:
La leucodistrofia metacromática (LDM) es una enfermedad poco frecuente que se caracteriza por desmielinización progresiva a nivel del sistema nervioso central y periférico. En la mayoría de los casos, es causada por una actividad deficiente de la enzima arilsulfatasa-A. Pertenece al grupo de las leucodistrofias, que son trastornos hereditarios de la sustancia blanca asociados con una variabilidad fenotípica y una heterogeneidad genética importante. El fenotipo de la LDM suele relacionarse con la edad de presentación, que puede variar desde la infancia hasta la adultez. Cuando se presenta en la edad adulta, puede debutar con manifestaciones neuropsiquiátricas, lo que lleva con frecuencia a diagnósticos erróneos.

REPORTE DE CASO:
Se presenta el caso de una paciente adulta que debutó con un cuadro clínico caracterizado por cambios comportamentales progresivos, con posterior inicio de manifestaciones clínicas motoras. El diagnóstico de LDM se sospechó a partir de la clínica y los hallazgos típicos en la resonancia magnética (RM) cerebral, y se confirmó con la detección de actividad deficiente de la arilsulfatasa-A (ARSA) y la secuenciación del gen ARSA que confirmó la mutación en estado homocigoto, compatible con este diagnóstico.

DISCUSIÓN:
Destacamos en este caso la importancia de la sospecha clínica, el reconocimiento temprano y el manejo multidisciplinario como factores pronósticos del curso de la enfermedad, ya que en la actualidad no hay tratamiento definitivo para la enfermedad.

Cultural security regulation in Europe: A case study of immigrants in Finland
Authors: Yeasmin Nafisa , Tkach Pavel
Published: July 2022

The cultural security of migrants in Finland is a rarely discussed topic. Like most European Union (EU) countries, Finland focuses the majority of its efforts on combating discrimination and, in many cases, overlooks aspects of cultural security for vulnerable minorities. Exactly such overlooking happened in 1996 when the Finnish legislation sufficiently limited ways of halal slaughtering — an essential ritual for Muslims. The subject of research is the cultural security of migrants in Europe with particular attention to Finland, reflected in analysed legal instruments such as the Finnish Animal Welfare Act 247/1996 and Animal Welfare Decree 396/1996 and academic papers defining challenges that religious minorities face in the European states. As discussed in the article legal concept of corporate due diligence can become this alternative aimed at harmonising halal standards, strengthening Muslim immigrants’ trust, and preventing misrepresentation of Muslim cultural security. This qualitative, descriptive, and conclusive research aims to identify potential mechanisms to foster cultural security for Muslim immigrants, discuss issues provoking cultural security from the perspective of the case study of halal slaughtering limitations, and answers the question of how the concept of due diligence can contribute to efficient regulation of cultural security in the future
Left Bundle Pacing in a Patient with Atrio-Ventricular Canal Defect Presenting with Atrial Standstill and Junctional Bradycardia

Published: July 2022

A 37-year-old woman with a history of incomplete atrioventricular canal
and an extensive history of corrective cardiac surgeries presented with
recurrent episodes of acute decompensated heart failure in the presence
of junctional bradycardia with chronotropic incompetence. The initial
plan was to proceed with implantation of a dual chamber pacemaker but
given high index of suspicion for the presence of atrial standstill in
the context of her extensive cardiac surgical history, we performed
electroanatomical mapping and echocardiography at the time of pacemaker
implantation that confirmed atrial standstill. Islands of electrically
functional atrial myocardium were detected. Pacing from these locations
resulted in local atrial capture, but failed to result in global atrial
electrical capture, mechanical atrial contraction, or atrioventricular
conduction. In light of the dismal outcomes of right ventricular pacing
in patients with atrial standstill, we implanted a left bundle branch
pacing lead that resulted in improvement of patient’s cardiac output and
prevented future admissions for decompensated heart failure in one year
follow up.

Published: July 2022

Arrhythmogenic cardiopathy is a genetic disease that mainly affects
young men and mainly involves the right ventricle. It is responsible for
up to 25% of sudden deaths in children under 35 years of age [1].
To make its diagnosis, certain criteria are required, such as the
characteristic electrocardiographic alterations in sinus rhythm, the
presence of documented ventricular tachycardia and structural
abnormalities especially in the right ventricle [2]. We present the
case of a 25-year-old male patient with a confirmed diagnosis of
arrhythmogenic cardiopathy who underwent ablation with a ventricular
tachycardia catheter with an endocardial -epicardial approach.
Fabrication and Characterization of Oleofoams Composed of Tribehenoyl-glycerol: Toward a Stable and Higher Air-content Colloidal System
Authors: Matsuo Kazuki
Published: July 2022

Oleofoams have attracted great interest for many personal care
applications due to their favorable physicochemical properties,
including texture and detergency. To explore the potential use of
mixtures of high-melting fat crystals [tribehenoyl-glycerol (BBB)]
and edible oils as low-cost and stable aeration systems, we created
oleofoams composed of olive oil and BBB. By whipping BBB/olive oil
oleogels following rapid cooling and subsequent heating, we succeeded in
preparing oleofoams without emulsifier additives. The mixtures of
BBB/olive oil formed oleofoams at BBB concentrations of 4.0–20.0 wt.%.
The resultant oleofoams maintained their overrun rates and did not
coalescence, even with additional whipping after the overrun rate was
maximized. More tightly arranged bubbles and concentrated bubble size
distributions, as well as stronger interfacial elasticity, were
attributed to increasing BBB concentrations, and thermal results
revealed that more heating was required to damage the foam structure.
The characteristics of these new oleofoams were closely related to their
BBB concentrations, and observed effects were attributed to the network
structure of the thickened crystal layer and enhanced gelling in the oil
phase.

OBJECTIVE

To compare the effect of an isocaloric multifactorial diet with a diet rich in monounsaturated fatty acids (MUFA) and similar macronutrient composition on pancreatic fat (PF) and postprandial insulin response in type 2 diabetes (T2D).

RESEARCH DESIGN AND METHODS

According to a randomized controlled parallel-group design, 39 individuals with T2D, 35–75 years old, in satisfactory blood glucose control, were assigned to an 8 week isocaloric intervention with a multifactorial diet rich in MUFA, polyunsaturated fatty acids, fiber, polyphenols, and vitamins (n = 18) or a MUFA-rich diet (n = 21). Before/after the intervention, PF content was measured by the proton-density fat fraction using a three-dimensional mDIXON MRI sequence, and plasma insulin and glucose concentrations were measured over a 4 h test meal with a similar composition as the assigned diet.

RESULTS

After 8 weeks, PF significantly decreased after the multifactorial diet (from 15.7 ± 6.5% to 14.1 ± 6.3%; P = 0.024), while it did not change after the MUFA diet (from 17.1 ± 10.1% to 18.6 ± 10.6%; P = 0.139) with a significant difference between diets (P = 0.014). Postprandial glucose response was similar in the two groups. Early postprandial insulin response (incremental postprandial areas under the curve [iAUC0–120]) significantly increased with the multifactorial diet (from 36,340 ± 34,954 to 44,138 ± 31,878 pmol/L/min; P = 0.037), while it did not change significantly in the MUFA diet (from 31,754 ± 18,446 to 26,976 ± 12,265 pmol/L/min; P = 0.178), with a significant difference between diets (P = 0.023). Changes in PF inversely correlated with changes in early postprandial insulin response (r = −0.383; P = 0.023).

CONCLUSIONS

In patients with T2D, an isocaloric multifactorial diet, including several beneficial dietary components, markedly reduced PF. This reduction was associated with an improved postprandial insulin response.

Due to the increase in diseases in the musculoskeletal system, regenerative medicine is now developing various bone substitutes. Not all scaffolds, due to their shortcomings, are applied for every application. Patients should be provided with basic product information and other warnings about health risks or measures to be taken. From the establishment of the purpose of the biomaterial to apply, several stages of the life cycle can pass. To ensure the biocompatibility of medical devices, there is a legislative framework and standards. They cover the full cycle from testing to market authorization, surveillance, and recall (ISO 15225:2010, ISO/IEC 33001:2015). We have developed the life cycle of bone substitutes and can offer an approach to evaluate operations based on the requirements of the ISO/IEC 33001:2015 series.

The article solves the problem of assessing duration of the functioning of municipal solid waste landfills based on the environmental risk management. To assess the environmental risk, an approach is applied based on the use of two methods, which are based on: the possibility of obtaining a functional dependence of the environmental risk of a landfill on the rate of its filling; a probabilistic estimate of the costs required to eliminate the possible consequences of the operation of landfills, formed taking into account the data used in accounting. Analytical expressions were obtained to estimate the optimal operating time of the landfills, their environmental risk, funds means for protecting the environment and compensation for damage depending on their area, as well as the dependence of the total costs on investing in the environmental protection relative to profitability. For calculations, data on potential costs and values of landfill areas were used on the example of officially registered landfills of municipal solid waste in Moscow region. Application of the proposed approach allows to predict the optimal environmental risk for a municipal solid waste landfill, while its value is significantly lower than the environmental risk of similar operating landfills in Moscow region. In the presence of a given time of functioning of the landfill for municipal solid waste, the application of the developed approach makes it possible to predict the costs required for its maintenance.

Currently, the mining industry of the Republic of Uzbekistan is dominated by an open method for solid minerals extraction. In the open pit mining, dust is the main adverse production factor. Its concentration in the environment depends on the development technology, the type and humidity of the mineral and host rocks, the mining equipment used, anti-dust measures, etc. Increase in the volume of mineral extraction due to the intensification of production processes and the introduction of high-performance equipment leads to an increase in the level of dust generation at the workplaces. In this regard, the fight against dust as a harmful professional factor remains an urgent task. In a dusty atmosphere, especially with a high concentration of hazardous suspended particles, various means of individual respiratory protection are used. This allows a significant reduction in the inhaled fraction. Conducted research proved that the real coefficients of respiratory protection in the modern personal protective equipment in the production conditions do not correspond to the declared ones. The main reason is the penetration of the unfiltered air into the area under mask through the gaps between the protective mask and the face of the worker. The necessity of developing a methodology for the selection of respirators that will provide reliable protection of the respiratory organs of the workers was identified. The dust load attributable to the respiratory organs of a miner is determined considering the use of BPS and ASDA respirators.

Hotels and all places of accommodation related to them are the objects that require special attention to ensure the safety of people. Large industrial enterprises often have hotels, holiday homes and other tourism facilities on their balance sheet. In Russia, there are regulatory documents that define the basic requirements which ensure minimum required conditions for the fire safety in places of temporary accommodation for people with a night stay. The purpose of the article is to develop effective ways to encourage hoteliers to create fireproof interiors in the hotel buildings that ensure the safe stay of guests and staff in them, which is also relevant for places of temporary accommodation of people as part of industrial facilities. The article presents an analysis of statistical data on the causes of outbreak and development of fires in the hotels. Provisions of the current Regulations on the classification of hotels in terms of the fire-prevention state of the object of protection are considered. Special attention is paid to the need to use certified reduced fire hazard textile materials and products in the hotel interiors. It is proposed to supplement the scoring criteria with an indicator of the use of flame-retardant textiles in the hotels, as a factor that significantly affects the fire safety of people temporary accommodation places. A model for assessing the level of fire safety is proposed on the basis of a risk-based approach when assigning a certain category to a hotel, which consider the characteristics that affect the state of fire safety. Proposals are developed to include the fire safety indicators in the Regulations on the classification of hotels.

Risk indicators, as a rule, are integral values for certain recipients (people, equipment, buildings, and structures) considering the frequency and degree of their damage as the result of exposure to hazardous factors of possible accidents with the release of hazardous substances. Risk indicators are used for assessing the efficiency of the compensatory measures, new industrial and fire safety requirements, or the risk of deviations from them when developing special technical conditions, safety case for hazardous production facilities. The list of the main calculated risk indicators was formed back in the 1970s–1980s. For example, in the domestic and foreign practice, the following indicators of the risk of people death are used: potential risk (individual risk), collective risk (average rate of death), social risk (societal risk), individual risk (there is no foreign analogue). Overview of the approaches to the calculation of these indicators is given in the article, it is shown that they are generally accepted. A new approach to the calculation of risk indicators is proposed, which allows to consider the location of people and the time of their stay in more detail. Consider, in particular, dynamics of changes in the number of people at the facility, and in its vicinity during a given period, and the likelihood of people being in different places of the potential hazard zone at a particular point in time. These innovations make it possible to consider, for example, presence of the employees in different places during the working day, temporary gatherings of people during the day, for example, at the lunchtime in the canteen. Example of performing calculations according to the presented methodology is given. Consistency of the obtained results is shown.
