The population protection system in the Czech Republic is briefly explained, which has been fully under the responsibility of the Ministry of the Interior of the Czech Republic since 2001, but a number of other central administrative authorities (ministries, special institutes and institutions, research institutes) are also involved in its implementation. In addition to legal standards and implementation decrees, the Czech Republic security strategy and the concept of population protection are also presented. A separate part is devoted to the last valid Population Protection Concept from 2021, and it is emphasized here that the concept places great importance on the population’s preparedness for dealing with extraordinary events and crisis situations. The Model Action Activity of the Integrated Rescue System in the Czech Republic is presented in the next section. Although many model action activities have already been published in the Czech Republic, unfortunately such a safety management plan has not yet been published for the extremely hazardous natural disaster „Tornado“. This subsection briefly explains how the Intergreted Rescue system intervenes in emergency and crisis situations. A separate part is devoted to the hazardous and strong tornado in Moravia in 2021, where a total of 6 people lost their lives and another 200 were injured, many were hospitalized. Material damage after the tornado’s rampage climbed to dizzying heights. The wave of solidarity with the affected population has reached unprecedented proportions not only in the Czech Republic. At the end of the contribution, the authors present their own proposal for the future, how to continue working in this area, from the preparation and convening of a national security conference in the Czech Republic to the preparation and publication of the Model Action Activity of the Integrated Rescue System in the Czech Republic in the disaster event of a tornado.","PeriodicalId":304895,"journal":{"name":"Challenges to national defence in contemporary geopolitical situation","volume":"151 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117347397","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}

{"title":"Parameters and Influences for an Evaluation System of Trafficability of Vehicles on Terrain","authors":"Klara Cibulová, Martin Priesner","doi":"10.47459/cndcgs.2022.1","DOIUrl":"https://doi.org/10.47459/cndcgs.2022.1","url":null,"abstract":"The paper deals with the investigation of parameters and influences for the system of evaluating the trafficability of vehicles through the terrain. Trafficability is one of the main aspects to ensure the movement of own troops, which falls into the main task of the Engineer troops - combat and general engineering support for all types of activities and operations of the army. Trafficability is the ability of a vehicle to move in rough terrain or on damaged roads and depends on many factors. The most used tool for determining trafficability in the Czech Army is the penetrometer. It is the PT-45 penetrometer, which is described in the Žen 2-16 Military Roads and Ways and the main evaluation criterion is the weight of the vehicle. Within the framework of international cooperation, soldiers encounter the manual FM 5-430-00-1 Design and design of roads, airports and heliports during events on the battlefield - road design, which works with a cone penetrometer and evaluates the throughput of the vehicle based on other factors such as properties of tires, ground clearance, engine power, etc. Inaccurate or incorrect evaluation leads not only to a stop the engagement of individual vehicles, but the entire convoy, which in terms of the operational task stops the manoeuvre and may lead to failure of the order. Therefore, it is important to know what parameters and influences have a fundamental influence on the system of evaluating the trafficability of vehicles, whether it would not be appropriate to add other aspects that will lead to higher accuracy of measurement, or, conversely, to exclude some. In solving this task, the authors decided to use the above-mentioned manuals and their evaluation systems. The objectives of the paper were achieved by analysis and calculations of individual parameters listed in these regulations, which affect the trafficability through the terrain, so that the degree of dependence is determined. It was found that some parameters have a major impact on trafficability and it is necessary to take into account even a slight change in these values. In contrast, other parameters are negligible as a result. These calculations confirm the suitability of updating the evaluation system for the telescopic penetrometer PT-45 to determine the trafficability of vehicles, so that it is possible to obtain more accurate results of measured values of the Czech army in the performance of tasks.","PeriodicalId":304895,"journal":{"name":"Challenges to national defence in contemporary geopolitical situation","volume":"218 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134320710","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 successful accomplishments of EDA initiatives depend on the ‘national appetite’ of pMS. The results of the research suggest a limited Lithuanian interest in the various EU programs, supervised by the EDA, that could boost the developments of the indigenous defence industry and research related to defence.","PeriodicalId":304895,"journal":{"name":"Challenges to national defence in contemporary geopolitical situation","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117175480","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}

We draw on theoretical knowledge and also on practical experience that members and officers of the integrated rescue system in their daily practice are involved in a number of highly traumatic emergencies and crisis situations. The negative impact of dealing with emergencies and crisis situations has primary or secondary impact on their psychological state. Almost in their daily practice they encounter emotionally stressful situations such as traffic accidents accompanied by severe injuries or death of the participants, mass disabilities of persons, encounters with death (in various forms: natural death, death as a result of a criminal act, etc. ), notification of deaths to survivors, dealing with psychologically and physically demanding conflicts with persons showing elements of aggression and aggressive (verbal and physical) behaviour, interventions against armed offenders, implementation of crisis communication (personal or telephone) with persons demonstrating suicidal intent, implementation of crisis communication with affected persons or their family members, implementation of communication with persons with specific needs (e.g. etc.), implementation of multicultural communication, etc. Thus, traumatic events affecting their psychological state occur in their daily practice. That is why a psychological examination (analysing their mental health as well as their level of resilience to stress, etc.) is part of their recruitment into the basic components of the integrated rescue system. Subsequently, their lifelong learning process includes post-traumatic care, strengthening resilience and the ability to cope with traumatic and stressful events, prevention of post-traumatic stress disorder, prevention of psychological distress or burnout syndrome, etc. Taking into account the above-mentioned facts, the basic components of the integrated rescue system have a system of providing post-traumatic care, and the characteristics of each system and the issue of providing this care is the subject of this paper .","PeriodicalId":304895,"journal":{"name":"Challenges to national defence in contemporary geopolitical situation","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114675697","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}

We have determined the initial values of the volume resistance of epoxy composites and the temperature values when the samples lose their dielectric properties. The effectiveness of the use of electrospark water hammer treatment with the subsequent introduction of a bidisperse filler at optimal concentrations, which will increase the resist ance of protective coatings, is shown.","PeriodicalId":304895,"journal":{"name":"Challenges to national defence in contemporary geopolitical situation","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127348496","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}
