This causes emissions of dust and greenhouse gases and into the atmosphere and leads to negative climate changes. For this reason, European Union countries have been implementing a climate and energy policy for many years, which in the area of heating is aimed at making it more efficient and sustainable. This requires the introduction of low-carbon technologies and the reduction of fossil fuel consumption by increasing the share of renewable energy sources. Modern, efficient and smart heating systems should guarantee reliable heat supply while reducing the environmental impact. The article discusses the direction of change and development of district heating systems through the introduction of innovative technologies. The new generations of 4GDH and 5 GDH district heating systems are described and the benefits of their use are indicated. The concept of smart district heating networks, their structure and the advantages of their implementation are discussed. The possibilities of creating smart energy systems using renewable energy sources and heat storage technologies were also indicated. The activities of Polish district heating companies in the introduction of smart heat networks are presented, based on research conducted.","PeriodicalId":315981,"journal":{"name":"System Safety: Human - Technical Facility - Environment","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131654251","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 load-bearing capacity of the boom sub-assembly rotation node was tested in a mobile crane. When identifying the load, the uneven compliance of the supporting components was taken into account. The considerations are illustrated with an example of a mobile crane slewing bearing with a lifting capacity of 50 tons. The basic problems of building the computational model are discussed and the results of the load bearing capacity of the slewing ring bearing for different positions of the load-bearing component of the tested machine are presented. An analysis of the load of the rolling elements in a slewing ring bearing was carried out and the reasons for changes in the load capacity in relation to the methods of calculating the load capacity, assuming non-deformability of the bearing rings, were indicated. It has been shown that deformations of the supporting frames are so large that they significantly change the distribution of forces transmitted by individual bearing rollers.","PeriodicalId":315981,"journal":{"name":"System Safety: Human - Technical Facility - Environment","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130833352","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}

First of all, only substances whose quality meets the guidelines of the modern, current Polish standard PN-EN ISO 9235: 2021-12 (ICS 71.100.60 - Essential oils) and which are classified as essential oils can be used in aromatherapy, i.e. for therapeutic purposes. A very important role in obtaining essential oils of high therapeutic quality is played by the place and method of cultivation of the plant from which the oil is extracted, safety in maintaining the purity of the essential oil during its extraction, and compliance with the special requirement to label the essential oil package. Fragrance, synthetic and natural oils do not meet these requirements and cannot be used for therapeutic purposes.","PeriodicalId":315981,"journal":{"name":"System Safety: Human - Technical Facility - Environment","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126107086","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 universal process of digitization and easy access to the Internet allowed for the development of this type of information source. The problem is how to classify this phenomenon, whether the reviews published on the Internet are free advertising for a given enterprise or rather a threat related to the negative attitude of customers. The aim of this paper is to analyze the respondents’ approach to publishing reviews on the products and services they purchased. The author wanted to check whether the respondents had will to share their reviews with other Internet users, why they wrote such reviews, if they wrote more often positive or negative reviews. A short online survey, which was published in the period January 2021 - June 2021, was used as a source of information. The respondents were people using both traditional shops and e-shops who wanted to share their experience in writing reviews on the Internet.","PeriodicalId":315981,"journal":{"name":"System Safety: Human - Technical Facility - Environment","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130614834","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}

Physiological changes taking place in the body of a young person correlate with changes in the perception of his body. The article aims to define the role of social media in influencing the perception of the body by adolescents aged 16-19. The survey questionnaire was used as a quantitative research technique created by the authors and the Sylwetek test (DRS, Contour Drawing Rating Scale). 190 teenagers were included in the study. The conclusion to be drawn from the conducted empirical study is that social media are an important factor in creating a vision of one’s own body among maturing people. The statistical analysis of the test results showed a statistically significant discrepancy between the ideal self and the real self in the body image among the examined group of young adolescents.","PeriodicalId":315981,"journal":{"name":"System Safety: Human - Technical Facility - Environment","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122927012","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}
