As a result, EU roads are some of the safest in the world. The EU has introduced mandatory fitment of electronic stability control systems on all vehicles and advanced emergency braking and lane departure warning systems, contributing to a reduction in fatalities. Modern active safety technologies are increasingly being implemented in vehicles. The purpose of this report is to present a complex of systems, their functionality, benefit and significance for increasing road safety.","PeriodicalId":183669,"journal":{"name":"Innovative STEM Education","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133361763","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}

Collective efficacy is a construct directly related to self-efficacy, which originates in Bandura`s social-cognitive theory. Theoretical perspectives on teachers` perceptions of their collective efficacy and how these affect their success in working with students are examined. The teaching profession is ancient and of high social importance by its nature and is distinguished by the special value of the human factor in it. For the teacher's work, his personal efficacy, or self-efficacy, as well as the collective efficacy in organizational terms, are of essential importance - how the quality of the work of each teacher is affected in an individual plan, when there is a perception of a high general success rate among the entire team.","PeriodicalId":183669,"journal":{"name":"Innovative STEM Education","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122678405","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 main idea is to determine heart rate variability only through the ANS, which includes sympathetic and parasympathetic nerves. The proposed approach is related to using a Holter device to record the intervals between heartbeats and a 3D virtual reality device by applying a virtual helmet (Photontree Pro 3D). A spectral method was used for heart rate variability (HRV) analysis. During heavy physical work or sports (running), the autonomic nervous system (sympathetic nervous system) is activated, which decreases the HRV. Similar results are obtained when simulating a stressful situation through a 3D game. A 3D game was developed using the Java programming language (Java3D) for the conducted experiments. The article shows the results of the comparative analysis of two types of recordings: at rest and during a 3D game (virtual reality). From the obtained results, it can be seen that in a simulated stressful situation, the ANS changes, and from there, the HRV also changes.","PeriodicalId":183669,"journal":{"name":"Innovative STEM Education","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114781069","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}

An important aspect in the processing and access to this type of data is the ability to reliably protect it from unauthorized access. The article shows an automated system for registration and mathematical analysis of cardiac data and methods for their protection. Information protection is achieved by implementing two-factor authentication. The characteristic of two-factor authentication is that access to the system takes place in two stages: entering a password as the first step and a code/key as the second. In this way, for protection, unauthorized access to the patient 39 file, including personal information and results of cardiac tests, is prevented.","PeriodicalId":183669,"journal":{"name":"Innovative STEM Education","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128138245","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}
