Enterprises in the food sector want to meet customer expectations and the requirements set out in national and international legislation and implement a variety of tools, methods, or techniques in their organizations. Increasing health safety and even improving the quality of produced food is possible through properly planned training of employees. This training should be tailored to the capabilities and needs of both employees and the enterprise. Nowadays, with the era of the COVID -19 pandemic, training in food safety becomes of particular importance, as the production of safe food is a basic objective to be taken into account by all employees. Under these circumstances, it seems appropriate to carry out additional training in the prevention of the spread of COVID-19 in the context of the health safety of the produced food. The aim of the present paper is to examine the subjective assessment of food employees regarding the amount and quality of food safety training in the COVID-19 pandemic. The research is a pilot study conducted at the turn of December 2020.","PeriodicalId":315981,"journal":{"name":"System Safety: Human - Technical Facility - Environment","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130594387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The possibility to predict the work-related injuries in the underground coal mines, based on application of the neural networks, is analyzed in this work. the input data for the network were obtained based on a survey of 1300 respondents. After analyzing the input data influence on the network output, 14 most influential inputs were selected, with help of which the network correctly predicted whether the worker would suffer the work-related injury or not, with 80% precision. The two models were developed, based on the multilayer perceptron (MLP) and radial basis function (RBF) networks. The two models’ results were compared to each other. The sensitivity analysis was used to select the most influential parameters, like mine, age of miners, as well as their work experience. The parameters were further analyzed by use of the descriptive statistics. The selected parameters are direct indicators of problems that can cause injuries. The obtained results point to the fact that the work-related injuries can be successfully predicted by application of the artificial neural networks. The proposed models’ importance is reflected in the clear indicators for enforcing the stricter occupational safety and organizational measures in order to reduce the number of work-related injuries in underground mines.","PeriodicalId":315981,"journal":{"name":"System Safety: Human - Technical Facility - Environment","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116479772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Article presents the definition of embedded system and, also, introduces the definition of the author. What is more, article briefly presents the most popular and developed in the fastest way exemplary systems: ARM, STM32, Raspberry PI, Sony Spresense and NvidiaJetson. Moreover, the main reasons were described why the embedded systems are used in more and more solutions and the factors that strengthen this trend have been noted: labor costs reduction through automation, reduction of costs of development of a new product through the possibility of making quick changes and reduction of product testing time, value creation potential and, also, the way to individualize the possibilities of electronics. Also, the examples of usage of those systems were presented. Finally, the practical side of programming and testing the embedded systems were described: ‘radar‘ (a torch) for blind people, help with balance disorders and the device to help with problems with orientation in space.

They often do not realize that production of such products requires more and more materials, energy and other means of production. All this leads to high exploitation of the environment. Even if the resources of the natural environment are not exhaustible, they do not keep up with their rebuilding at this pace of exploitation. That is why social awareness and responsibility both of producers and customers play such an important role. They are one of the instruments needed to operate in accordance with the concept of sustainable development. The aim of the research was to examine social awareness and responsibility among customers of service enterprises. The research was conducted with the use of an online survey, which allowed to show whether the customers of such enterprises are interested in the concept of the sustainable development, if they take it into account when using various services. The need for environmental education was indicated, which could strengthen the social awareness and responsibility among Polish customers.","PeriodicalId":315981,"journal":{"name":"System Safety: Human - Technical Facility - Environment","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114667318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A crisis situation may, on the one hand, have a negative impact on the development of the company, but, on the other hand, it may provide a stimulus and have a constructive effect on its functioning. One of the factors influencing the ability to function of a business, including crisis situations, is its organisational culture. Therefore, a company responding to the situation should assess the conditions both in its environment and inside it and verify the artefacts, the system of values and the main principles that are the basis for building an organisational culture. Many companies that are dealing with a crisis situation decide to undertake a conscious process of cultural transformation. However, it requires the management to take appropriate actions and the time of a crisis situation is a test for many companies – whether in such a difficult moment something can still be done with the organisational culture, or whether the entrepreneurs can only wait for its inevitable impact on the functioning of the company. The subject of this article is the impact of a crisis situation on changes occurring within the organisational culture. The study attempts to evaluate the role of organizational culture in crisis situations based on the current state of knowledge and crisis events related to COVID-19.","PeriodicalId":315981,"journal":{"name":"System Safety: Human - Technical Facility - Environment","volume":"6 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116116614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was shown, that this process is particularly important in the cause of industrial enterprises, in which the number of accidents is the largest. In these enterprises, one of the most often practiced methods is the PN-N-18002 method. However, it was concluded this method has some limitations. They concern the way of assessing the risks in the traditional number scale, which is less precise than the fuzzy triangular number (using in FAHP). Therefore, the aim is to improve the process of assessment in industrial enterprises by integrated the PN-N-18002 method with the FAHP method (Fuzzy Analytic Hierarchy Process). The test of the proposed method was made for three machine operator positions used to aggregate extraction in one of the Podkarpacie enterprises. These positions were: loader operator (Ł-34), digger operator (CAT 323), dredge operator (300/250 KREBS 10/8). The concept of the method was to identify in a precise way what is the greatest extent danger to the operators of these workplaces. It was shown, that it is the work at height. It was concluded, that this method can be practice to risk assessment of other workplaces, among others from industrial enterprises. The originality is the integrated risk assessment method (PN-N-18002) with the fuzzy multicriteria decision method (FAHP) as part of achieving the precise results of risk assessment.","PeriodicalId":315981,"journal":{"name":"System Safety: Human - Technical Facility - Environment","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121737086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
