The article presents an analysis of the results obtained from the testing of simply supported reinforced concrete beams subjected to four-point bending. The beams, with two levels of steel reinforcement (ρs1=1.26%, ρs2=0.71%), and dimensions of 0.12x0.30x3.30m, were subjected to loading involving a sudden increase in force with multiple unloading cycles to zero. The study included comparative analysis of deflection results obtained from experimental tests (calculated based on the curvature of the element and readings from measurement devices) with deflection values obtained through calculations based on two selected standards. Real values of ultimate bending moments were also compared with theoretical values. Additionally, compressive strength tests were conducted on eight cubic concrete specimens with a side length of b=150mm, obtained for each concrete batch. They constitute accompanying studies. Using standard procedures, strength and statistical parameters were estimated and evaluated, taking into account the assessment of the quality of the concrete production used to make the reinforced concrete beams. Ensuring compliance with the process of producing full-sized reinforced concrete beams with existing standard procedures, as well as attention to the quality of concrete production, contributed to achieving satisfactory results in the experimental tests. Knowledge about the impact of loading on mechanical properties enables effective management of factors shaping quality to obtain a construction material with optimal parameters.

Research background: For many years, the authors have been dealing with the issues of student inventiveness and the related innovation and creativity. The presented work refers to the sources, understood as shaping the pro-engineering attitudes of young people, which in effect translates into the creation of new, often innovative solutions in the field of technology. Purpose: The aim of the research is to identify activities related to knowledge in the field of science and technology during the period of attendance at secondary school. These activities include knowledge and skills acquired at school and other relationships between young people and science and technology resulting from passions and passions. An additional goal is to indicate proposals for development in this area, mainly concerning the teaching process. Methodology: The source of data for the conducted analyses are the results of surveys conducted in 2021. The analysis of the acquired data was carried out using the AHP (Analytic Hierarchy Process) method. The AHP method, by incorporating expert opinions, allows you to achieve an additional goal. This is an original approach to the analysis and interpretation of survey results. It will not replace classical statistical analyses of varying complexity, but it can be a kind of complement. Findings: The implementation of the research indicated a significant interest of young people in the issues of science and technology, and the obtained data allowed to take a comprehensive look at the education of young people in this area and present suggestions for the modification of teaching forms. This may contribute to reducing the shortage of engineering staff and researchers creating new innovative solutions in many countries. This will be an important factor in economic development based on innovative technologies.

Commercialization processes are modeled and analyzed from the point of view of the implementation of activities under particular stages. These issues are the subject of many studies and analyzes, which is why the extensive literature is available on this subject. Technology valuation at various stages of the commercialization process is a separate issue. Such valuation is prepared in most cases by consulting companies for determining the price in the buying and selling processes. These valuations use known methods also used in other cases, e.g., real estate valuation. The work carried out presents the author’s concept of the commercialization process model, taking into account the costs and value of the technology at various stages of the product life cycle. The model uses a stochastic approach to determine future revenues and costs, which allows estimating the value of the technology by or in determining the probability of assessment validity. The proposed stochastic approach greatly increases the chances of using the presented solutions in practical activities related to technology valuation for the purposes of purchase and sale transactions.

W pracy poruszono zagadnienie komercjalizacji wynalazków w aspekcie prawdopodobieństwa sukcesu rozumianego jako zysk ze sprzedaży wyprodukowanych towarów. Zaproponowano model procesu komercjalizacji ze wskazaniem punktów decyzyjnych i odniesieniem do skali TRL. Przedstawiono wyniki symulacji procesu komercjalizacji dla pewnych wartości prawdopodobieństwa warunkowego przypisanego punktom decyzyjnym. Jest to autorskie spojrzenie na proces komercjalizacji, jednak nie sprzeczne z innymi występującymi w literaturze przedmiotu.

The paper discusses the issue of commercialization of inventions in terms of the probability of success understood as the profit from the sale of manufactured goods. A model of the commercialization process was proposed with the indication of decision points and reference to the TRL scale. The results of the simulation of the commercialization process are presented for certain values of conditional probability assigned to the decision points. This is the author’s view of the commercialization process, but not contradictory to others presented in the literature.
