The purpose of the article was to analyze the problems currently standing in the way of more effective application of the risk-based approach methodology in the field of technogenic safety management. Methods — theoretical, inductive method, analysis of own experience, adopted normative legal acts, other publications. The main results of the work include the following: • despite the broadest use of the concept of “risk” in the field of technogenic safety management, there is no generally accepted interpretation of it to date; • often the evaluative concept of “risk” is mistakenly used instead of objectively existing risk factors; • quantifiably technogenic risk should be characterized by indicators of numerical nature, having vector objects, since two components should be indicated for the complete assignment of the indicator: the probability and the amount of damage; • experience shows that the methods of assessing the probabilistic component of risk indicators recommended by regulatory documents on the analysis and quantification of technogenic risk are accompanied by a very large uncertainty, therefore, instead of the traditional point statement, a more adequate method of assessment is the use of an interval approach that takes into account and allows quantifying this uncertainty; • the analysis showed that the so-called frequency approach, which is most often used to assess the probabilistic component of technogenic risk indicators, is used improperly, has no basis, since, as a rule, the phenomenon of statistical stability is not observed in the object area of the technosphere, there are no general aggregates; • in society and even among specialists, by now there is no understanding of the need to express all three components of damage from an accident (explosion/fire) in monetary terms, without which it is impossible to estimate and express the amount of total damage: —  in conclusion, four key problems that hinder the more effective use of the risk-based approach methodology in the field of technogenic safety management are listed; —  imperfection of the existing methodological base for the analysis and quantitative assessment of technogenic risk; — the problem of staffing in the field of technogenic risk management; — lack of national criteria for acceptable risk; —  complete disregard of the problem of uncertainty of the results of the COR, the lack of methodological support for the procedure of analysis and quantification of this uncertainty. Conclusion — the efforts of the entire community of specialists-researchers, legislators, practitioners engaged in various aspects of the problem of technosphere safety management are necessary to solve the tasks specified in the article.

This study analyzed the relative risks of migrant workers, and identified risk factors based on quantitative data for the systematic safety management of migrant workers. Many studies have found that migrant workers are more vulnerable to safety accidents than non-migrant workers. Nevertheless, there are few quantitative studies of migrant workers’ accident-risk in the construction industry, where safety accidents are most frequent. In addition, safety management for the identified accident risk factors has not been implemented systematically. To fill the gap, this study uses safety accident data from construction sites, from the +, for the methodical safety management of migrant workers. The t-test and multiple regression analysis methods are used to define the variance in non-migrant and migrant workers, and the risk indicators, respectively. The two analyses show that the results for migrant construction workers were 2.2% higher in safety accident severity than non-migrant workers, and significant factors are also different. This study’s results will provide critical guidance for the safety management of migrant construction workers.

The effectiveness and the safety of road construction depend on many factors that pose the greatest risk to system safety. The aim of this study is to conduct a comprehensive assessment for these risk factors to contribute to the safety performance of road construction. To achieve this goal, this study constructs a hierarchical safety assessment framework comprising comprehensive risk indicators according to rich work experience and a relevant literature review and then proposes a group AHP-PCA (group analytic hierarchy process-principal component analysis) to calculate the weights of relevant risk factors. The important rankings of a case study using GAHP-PCA show that professional skill, safety education, and work attitude are the most important factors, which are consistent with the experience and knowledge of road construction safety management. The results also demonstrate that judgment dispersion naturally existing in classical AHP can be effectively reduced when combined with PCA, which is the innovation point of the method given in this article.

AbstractThe article presents the element of occupational health and safety management in enterprises, with particular emphasis on the identification of occupational hazards. The factors that may be a source of occupational hazards have been classified and divided. The aim of this study was to assess the impact of occupational hazards on work safety in the opinion of employees of micro and small enterprises. The research was carried out using the proprietary questionnaire. The results were verified by means of a direct interview with elements of observation. The research was compared with the trends prevailing in the enterprises of the European Union countries according to the results of the research conducted by EU-OSHA. Polish respondents considered physical and psychophysical factors to be the main occupational hazards. The results turned out to be very similar to those presented by EU-OSHA in its publicly available reports. The basic principle of occupational health and safety management, i.e. identification of occupational hazards, is reliability and correctness. Identification of occupational hazards gives the opportunity to take correct and effective corrective and preventive actions reducing occupational risk, for example through the effective use of personal protective equipment, or a more detailed treatment of both introductory and instructional training. The article also highlights the migration of individual occupational hazards, which depends on many factors, both professional and non-professional.

Background. The article investigates the principles of budget financing, the principles of enterprise and corporate financing, and the principles of social entrepreneurship. The scientific approaches on the interpretation of the given principles of financing are generalized and systematized. Expediency of the separate principle’s application in the context of the municipal enterprise functioning is substantiated. The principles of the municipal utility enterprises financing are proposed with consideration to social significance of the municipal enterprises in the system of economic activity of the territorial community. Materials and methods. The historical method, analysis and synthesis, the method of deduction were used in theoretical systematization of the budget financing and enterprise financing principles. Derivation of the principles of financing utilities on the basis of scientist’s opinions systematization is performed using the inductive method. The conclusions of the study are formed by the abstract-logical method. Results. The principles of municipal utilities financing should be based on the principles of budget financing, as these enterprises are recipients of funds from local budgets.However, the utility enterprise operates on the commercial basis, the principles of its financing should take into account the principles of private sector enterprises financing. We have developed the principles of a municipal utility company financing, which are grouped into two categories – general and specific principles. Conclusion. We have proposed the principles of utilities financing with their division into universal and specific, taking into account the commercial nature of such enterprises and their social significance. And furthermore, these principles allow to justify the functions, methods and approaches to utility enterprise financing, which will be a topic for future research. Keywords: municipal utility enterprise, financing principles, budget financing, corporate financing.

Today, fixatives from natural raw materials are gradually replacing fixatives synthesized from chemicals. The arm of this research is the study of same useful resin in Vietnam for fixative substance in blending fragrance. We obtained Benzoin resin from Styrax tonkenensis Pierre plant in Ha Giang province, Canarium resin from Canarium Album L. in Dak Nong district, Dak Lak province, and Agarwood pulp of Aquilaria crassna plant in Binh Thuan province Vietnam. The material used in the experiment for the natural fragrance was taken from the project of Vietnam essential oils and related natural products. The method of this process is resin extraction by volatile solvents. The resin is dissolved in alcohol 96% and the distilled alcohol is removed to obtain absolute. The method of assessment of product quality in this study is using the olfactory to assess the odour of samples over time. Benzoin resin, Canarium resin, and Agarwood resin of Vietnam are useful fixatives in blending fragrance. The fixative ability of Benzoin resin absolute is not equal to the ability of Agarwood resin absolute but better than the ability of Canarium resin absolute. Through research and experiment, we can see Benzoin resin, Canarium resin and Agarwood resin are precious. They can be used as a good fixative in aromatherapy. This is a natural resin, a kind of resource available in Vietnam. Therefore, it is recommended for further research, exploitation, and effective use of this resource.

El presente estudio se enfoca en la necesidad que tienen los estudiantes como la brecha digital que les impide desarrollar un uso efectivo de herramientas tecnológicas y que las instituciones de educación superior en Ecuador deben de implementar dichas tecnologías del aprendizaje como herramientas didácticas para el fortalecimiento del conocimiento y la simulación de situaciones con apego a la realidad. Por tanto, el objetivo de esta investigación fue evaluar la usabilidad que tiene una aplicación móvil como herramienta para el aprendizaje por medio del análisis de descriptores: a. Pertinencia, b. Facilidad de uso, c. Personalización, d. Retroalimentación, e. Autenticidad, f. Habilidades del pensamiento, g. Trabajo colaborativo y h. Motivación, en función al desempeño pedagógico de un nuevo entorno como lo son las aplicaciones móviles. En consecuencia, se detalló una metodología con enfoque cualitativo por medio de un diseño no experimental y método inductivo basado en la descripción de las experiencias generadas por estudiantes con el aplicativo móvil de la institución. Como instrumento se seleccionó la encuesta estructurada por una escala de Likert valorada de (1-5) partiendo de “imperceptible” hasta “fuerte” en función a la aceptación de los ocho descriptores por parte de los encuestados. Por lo tanto, se planteó como población de estudio 1408 estudiantes y por medio de un muestreo probabilístico se calculó una muestra de 302. Así mismo, varios resultados pusieron a prueba las ventadas como también desventajas y dificultades que generó el aplicativo en el proceso de aprendizaje donde el 29,5 % de los estudiantes determina una motivación fuerte en el uso del aplicativo móvil, sin embargo durante el ejercicio de las clases el 59,3 % de los estudiantes han percibido frustración debido a la conectividad o al colapso del aplicativo. This study focuses on the need that students have, such as the digital divide that prevents them from developing an effective use of technological tools and that higher education institutions in Ecuador must implement these learning technologies as didactic tools for the strengthening of knowledge. and the simulation of situations with attachment to reality. Therefore, the objective of this research was to evaluate the usability of a mobile application as a tool for learning through the analysis of descriptors: a. Relevance, b. Ease of use, c. Personalization, d. Feedback, e. Authenticity, f. Thinking skills, g. Collaborative work and h. Motivation, based on the pedagogical performance of a new environment such as mobile applications. Consequently, a methodology with a qualitative approach was detailed through a nonexperimental design and inductive method based on the description of the experiences generated by students with the institution's mobile application. As an instrument, the structured survey was selected by a Likert scale valued from (1-5) starting from "imperceptible" to "strong" based on the acceptance of the eight descriptors by the respondents. Therefore, 1408 students were proposed as the study population and a sample of 302 was calculated through probabilistic sampling. Likewise, several results tested the advantages as well as disadvantages and difficulties that the application generated in the learning process where 29.5% of the students determine a strong motivation in the use of the mobile application, however during the exercise of the classes 59.3% of the students have perceived frustration due to the connectivity or the collapse of the application.

Abstract BackgroundIncreasingly the global policy direction is for patient-facing pharmacist prescribers. The ‘UK Prescribing Safety Assessment’ (PSA) was developed for medical graduates to demonstrate prescribing competencies in relation to the safe and effective use of medicines.ObjectivesTo determine PSA performance of final year undergraduate student pharmacists (year 4) and pre-registration pharmacy graduates (year 5) and explore their opinions on its suitability. SettingScotland, UKMethodsFinal year undergraduates (n= 238) and pharmacy pre-registration graduates (n= 167) were briefed and undertook the PSA. PSA questions were mapped to specific thematic areas with 30 questions over 60 minutes. Data was analysed using descriptive statistics. A questionnaire was completed to gauge opinions on appropriateness of the PSA.Main Outcome Measure PSA scoresResultsMean total PSA score for pre-registration graduates (64.4, SD 10) was significantly higher than for undergraduates (51.2, SD 12.0,) (p<0.001). Pre-registration graduates performed significantly better across all question areas (all p<0.001 other than ‘adverse drug reactions’, p<0.01). Hospital pre-registration graduates performed statistically significantly better than community with higher overall scores (67.4, SD 9.8 v 63.2, SD 9.8, p<0.05). Positive views on the appropriateness of the approach and the usability of the online interface were obtained from participants. ConclusionHospital graduates performed better than the undergraduates, but there is a need to improve prescribing skills in all, most notably in diagnostic skills. The PSA is acceptable to the participants. These results will help inform pharmacy curricula development and provides a cross-disciplinary method of assessment of prescribing competence.

The Aim of the paper is to show that the risk to critical infrastructure facilities (CIF) of structurally complex systems (SCS) should be considered as a multicomponent vector, whose set of parameters is subject to changes. Real safety estimation using the risk-oriented approach is impossible without a sufficient base of quantitative and qualitative characteristics of risk factors, as well as data on the status of facilities and processes that are exposed to such risk factors. Risk assessment always aims to estimate its quantitative indicators, which allows it to be used not only to assess industrial safety, but also to substantiate the economic efficiency of taken measures, conduct economic calculations of the required relief or compensation of lost health of workers and environmental damage.Method. The author suggests a method of risk synthesis (with game definition of the problem of countering possible external effects of various nature on CIF SCS) as one of the foundations of the design of advanced systems for monitoring safety threats to SCS. A special attention must be given to the effect of risk factors on the system of balanced safety and risk indicators, as prediction based on single indicators does not create a holistic image of the systems’ status and development trends.Result. Key methodological premises were formulated: from general problem definition of safety management through the synthesis the model of a controlled facility and its external and internal connections, solution to the problem of selection of priority protection facilities in terms of assuring efficient operation and general safety of SCS. As the basis of advanced systems for monitoring safety threats and risks, the paper suggests the concept of risk management aiming to create the mechanism, method and tools for the synthesis, analysis and prediction of emergency risks.Conclusion. The proposed method can be applied to a wide range of tasks of primary analysis, synthesis and quantitative estimation of the CIF-related risks and safety management of SCS of various purpose.
