    HEALTHY LIFESTYLE AMONG MIDWIFERY STUDENTS

    One of the main problems in our time is reduced physical activity and unhealthy eating, which is gradually becoming a risk factor for people in our society. If the nutrition to has to be balanced and rational, it is necessary that the expenditure of energy corresponds to the energy value of the food. Thus, a person preserves or increases his body mass, work capacity and resistance. The purpose of the research is to study and analyze the opinion of midwifery students regarding a healthy lifestyle. Material and metods: A survey was conducted among parents through an individual survey in April and May 2023. Used methods – documentary, sociological, statistical and graphic processing of the results. The results of the conducted survey indicate that during the time when they are free from studies, students prefer to go for a walk with friends (90.5%). Just over half of the respondents indicated that they eat twice a day (55%), followed by those with three or more meals a day (39%). There is a high proportion of students who consume fresh fruits and vegetables at least once a day (65%) and drink more than one liter of water

    Hypothesis for Hypersonic Flight development

    The aim of this work is to promote the hypersonic flight in order to improve both the affordability of the access to space and the terrestrial flight transportation increasing flight range and reducing flight time. A strategic air vehicle is envisaged partially employing state-of-the-art technologies focusing on configuration and feasibility studies. The purpose is obviously to indicate the technologies on which concentrating the design efforts. To enable the development of future spacecraft, it is believed that the effort have to focused on the development, at low cost, of new technology demonstrator aircraft based on suborbital “tourism spacecraft” and fighter aircraft. An important goal would be the development of small and affordable aircraft able to perform the hypersonic cruise

    Innovative time-based separation procedures for civil RPAS integration

    Purpose: This paper aims to suggest feasible solutions to overcome the problem of unmanned aerial vehicles integration within the existing airspace. Design/methodology/approach: It envisages innovative time-based separation procedures that will enhance the integration in the future air traffic management (ATM) system of next generation of large remotely piloted aircraft system (RPAS). 4D navigation and dynamic mobile area concepts, both proposed in the framework of Single European Sky ATM Research program, are brought together to hypothesize innovative time-based separation procedures aiming at promoting integration of RPAS in the future ATM system. Findings: Benefits of proposed procedures, mainly evaluated in terms of volume reduction of segregated airspace, are quantitatively analyzed on the basis of realistic operational scenarios focusing on monitoring activities in both nominal and emergency conditions. Eventually, the major limits of time-based separation for RPAS are investigated. Practical implications: The implementation of the envisaged procedures will be a key enabler in RPAS integration in future ATM integration. Originality/value: In the current ATM scenario, separation of RPAS from air traffic is ensured by segregating a large amount of airspace areas with fixed dimensions, dramatically limiting the activities of these vehicles

    Effective methodologies to derive strategic decisions from ESA technology roadmaps

    Top priorities in future international space exploration missions regard the achievement of the necessary matura-tion of enabling technologies, thereby allowing Europe to play a role commensurate with its industrial, operational and scientific capabilities. As part of the actions derived from this commitment, ESA Technology Roadmaps for Exploration represent a powerful tool to prioritise R&D activities in technologies for space exploration and support the preparation of a consistent procurement plan for space exploration technologies in Europe. The roadmaps illus-trate not only the technology procurement (to TRL-8) paths for specific missions envisaged in the present timeframe, but also the achievement for Europe of technological milestones enabling operational capabilities and building blocks, essential for current and future Exploration missions. Coordination of requirements and funding sources among all European stakeholders (ESA, EU, National, Industry) is one of the objectives of these roadmaps, that show also possible application of the technologies beyond space exploration, both at ESA and outside. The present paper describes the activity that supports the work on-going at ESA on the elaboration and update of these roadmaps and related tools, in order to criticise the followed approach and to suggest methodologies of assessment of the Roadmaps, and to derive strategic decision for the advancement of Space Exploration in Europe. After a review of Technology Areas, Missions/Programmes and related building blocks (architectures) and operational capabilities, technology applicability analyses are presented. The aim is to identify if a specific technology is required, applicable or potentially a demonstrator in the building blocks of the proposed mission concepts. In this way, for each technology it is possible to outline one or more specific plans to increase TRL up to the required level. In practice, this translates into two possible solutions: on the one hand, approved mission concepts will be complemented with the required technologies if the latter can be considered as applicable or demo; on the other, if they are neither applicable nor demo, new missions, i.e. technology demonstrators based on multidisciplinary grouping of key technologies, shall be evaluated, so as to proceed through incremental steps. Finally, techniques to determine priorities in technology procurement are identified, and methodologies to rank the required technologies are proposed. In addition, a tool that estimates the percentage of technologies required for the final destination that are implementable in each intermediate destination of the incremental approach is presented

    ABOUT SOME QUESTIONS OF QUALIFICATION OF THE ENVIRONMENTAL CRIMES COMMITTED WITH USE OF OFFICIAL POSITION

    В статье анализируются общеуголовные экологические преступления, совершенные с использованием служебного положения (в качестве квалифицирующего или особо квалифицирующего обстоятельства). Показано, что рассматриваемые деяния относятся к числу двухобъектных преступных посягательств, где в роли дополнительного объекта выступают интересы службы в конкретной коммерческой или иной организации, а также отношения, обеспечивающие нормальное функционирование конкретных органов управления публичной власти. Установлено, что обязательным объективным признаком экологических преступлений, совершенных с использованием служебного положения, выступает предмет - водные биологические ресурсы, иные объекты животного мира, лесные насаждения и др. Доказано, что общественно опасное деяние рассматриваемых составов преступлений характеризуется исключительно активной формой поведения – действиями виновного лица, незаконно использующего свое служебное положение. Сделан вывод о том, что субъективная сторона исследуемых посягательств характеризуется умышленной формой вины. The article analyzes the common environmental crimes committed with the use of official position (as a qualifying or special qualifying circumstances). It is shown that the acts in question are among the two-object criminal attacks, where the interests of the service in a particular commercial or other organization, as well as the relations that ensure the normal functioning of specific bodies of public authority act as an additional object. Stipulates that compulsory objective evidence of environmental crimes committed with abuse of official position, is the object of aquatic biological resources, other wildlife, forest stands, etc. Proved that socially dangerous act reporting of crimes is characterized by an active form of behaviour - the actions of the perpetrator, unlawful use his official position. The conclusion is made that the subjective side of the studied encroachments is characterized by a deliberate form of guilt
