    This study aims to determine the valuation value of Henbuk's startup by conducting qualitative and quantitative analyses. Henbuk is a startup engaged in e-commerce. The Henbuk startup is currently in the initial funding stage, and the founders are opening opportunities for investors, which can later support operational and development activities. In obtaining funding from investors, the Henbuk startup requires an initial assessment of the company's value. The score assessment consists of several indicators, e.g., quality of the founder and team, opportunity size, product and technology, competition, marketing, sales and partnerships, and the need for additional investment. The results of the value assessment are obtained by using the Scorecard Assessment Method. The results of this study may help to determine the real value of other start-ups for the investors in the future.

    The definitions of innovation have been transformed a lot over time since Schumpeter introduced his concept. Even recently one of the most prestigious innovation management references, the Oslo Manual have changed its concept. One rarely discussed aspect of the concept of innovation is that most of the definitions are referring to the business sector; only a few of them are referring to any kinds of organizations, including non-profit and governmental organizations. Any kind of organization must innovate sooner or later; therefore they have to learn how to manage innovation effectively and efficiently. That is why the broad type of definitions is recommended, involving not only for-profit organizations but non-profit and governmental organizations as well.

    How can the Japanese culture be implemented into the operation of a firm - partly a German property  working in Hungary. In my presented arcticle I have studied various organisational culture models, and compared them to the culture of our enterprise, seeking for similarities and contraries. I have studied the environmental factors and resources which have an effect on our production. During the investigation I have also considered how can we harmonize cultures of different nations and how it affects the production on the whole. I have also investigated the installation of robots, and searched for the solution how we can make our production much more economical. Due to the persistent decrease of population, and leck of professionals, the use of robots is neccessary to fulfill the customer requirements in time, with the sufficient quantity and required quality of goods. According to the Japanese Toyota-method,theautomatization of a technology can only be successful, if it is tested at least ten times, but –beacuse of the leck of time- we do not have the possibility of it. As the manufacturing parameters and observations have not developed the proper way, the scrap rate is higher than it is at firms, where is more available time for the building up of the technology.

    In recent years, additive manufacturing technologies have been increasingly used in both custom and small-series production. In such cases, the component must remain functional under realistic conditions.. This means that there must also has a load‑bearing capacity. In many cases, materials are already suitable for strength. However, in many cases (machine parts, outdoor use) the models need to operate reliably at higher temperatures. This seems to be solved by the most widespread additive manufacturing technology (FDM), with a new heat-resistant material, HT PLA. In many cases, the use of cooling is essential during manufacture, especially for parts with high overhangs where hardening of the material is required as soon as possible to achieve the correct surface quality. In this paper, we investigated the effect of cooling applied during manufacturing on the mechanical strength

    DP steels were extensively used in the vehicles industry due to its extraordinary combined properties of strength, ductility, formability and weldability which contributed great significance in reducing strength to weight ratio and CO2 emission. High strength steel i.e. DP steels (3 different grades) were experimentally investigated and thermophysically simulated using Gleeble 3500 simulator to determine softening and hardening in heat affected zone. Samples were heated to different peak temperatures (1350 °C, 950 °C, 775 °C and 650 °C), two cooling time (t8.5/5 = 5 s and 30 s) and Rykalin 2D model were selected. The hardness and microstructure of the specimens were tested and analysed. For longer cooling time (t8.5/5= 30 s), we observed that softening occurs in all grade of investigated DP steels to all sub-regions. But for shorter cooling time i.e. t8.5/5= 5 s the softening is higher in intercritical HAZ compared to other sub-regions for all the types of DP steel with short cooling time (t8.5/5 = 5 s). However, the hardening zone in the CGHAZ occurs when Tmax is 1350 ºC for DP600, DP800 & DP1000 steels but it is more prominent in DP800 as compared to others two steel grade.

    The implementation of aluminium alloy foam has more and more attention. Application of closed cell aluminium foam has made an impact in automobile and aerospace applications where crash energy absorption, vibration and weight reduction are obligatory [1,2,3]. The aluminium alloy foam is an advanced lightweight material providing high strength and stiffness at relatively low density. The technological use of aluminium alloy foam is difficult with the currently available technologies. In the case of open cell aluminium foams, the most common research areas for application are heat exchanger components, filters and sound damping elements [3]. The manuscript focuses on the manufacturing techniques of the aluminium alloy foams according to the application areas. First step is the investigation of the requirements for the application: what are the loads and the circumstances and why can we use aluminium foams. Second step is the knowledge of the producing methods of the foam or the component. And the last step is the investigation of the possible testing methods.

    The EU energy policy prioritizes the following principles: sustainability, competitiveness and security of supply and addresses the reduction of greenhouse gas emissions as a priority. The related EU policy (including the White Paper on Transport) outlines these principles, identifies goals and opportunities for action. At company level methodological guidelines and standard procedures can be used to assess the carbon footprint of the organization, to generate efficiency goals and to prepare action plans. In the Hungarian policy framework, a comprehensive National Sustainable Development Framework Strategy defines the basic principles for the analysis of the sectorspecific or regional strategies. Sustainable Energy Action and Climate Plans (SECAPs) integrate energy and climate issues and include interventions and improvements for the better use of renewable energy sources in transport at municipal level. As a summary it can be stated that exploration of the policy background would needed to influence the use of renewable energy sources for transport and definition of the development goals can help economic organizations to transform their mobility patterns and reduce related carbon footprint.

    It has been an accepted tendency in the industrial practice since the last third of the 20th Century to decrease the living labour demand of the manufacturing processes. One of the main tools of it is the automation of production. In the design, the construction and the programming of the developed automata, the results of electronics, informatics and mechatronics can be used. All of the scientific fields mentioned above undergo intensive development. By the application of the results achieved in the design of the applications, the monotonous, dangerous and tiresome work not requiring expertise can be assigned to machines. In the longer run, the application of the automata is beneficial also in financial aspect, since the costs of living labour are continuously growing, while that of the mechatronic and technological devices show a rather decreasing tendency. Reliability is also an important aspect. It is well known for everyone that a well-designed and programmed automatic device performs its task without mistakes. If there is any objection or breakdown, on the basis of the currently valid safety technology rules, the machine stops, does not trigger any damage and after its repair, work can be continued.

    Globalization and the recent explosive development of technology have significantly changed people’s lifestyles resulting in an increase in the number of people living a sedentary lifestyle. COVID-19 pandemic has exacerbated the situation and created an unprecedented situation in the world. In the present study, we investigate changes in the physical activity and sedentary behavior of adult workers caused by the coronavirus epidemic. In our online cross-sectional research, we used snowball methodology. The target group of the survey was adult workers. 108 people filled in the questionnaire, the majority (73.1%) are women, the average age is 37.18 years and most of them have higher degrees (Diploma: 74%, PhD: 14%). The present study revealed a decrease in physical activity and an increase in sedentary time for the employees in our study. Despite respondents detected a decrease in their physical activity, an increase was reported in the proportion of online training participants. The majority of respondents partially, or totally switched to work from home during the pandemic, which may further increase their sedentary lifestyle. We did not find significant differences among the domain of work and leisure time or occupational physical activity patterns. The workplace is a great opportunity for promoting physical activity and reducing sedentary time in the adult working population, therefore it would be important for organizations, decision-makers and health professionals to work on the design of strategies to these goals.

    Foundry technology uses a lot of several natural materials. Sands use for preparing mixtures whereby making moulds or cores. Sand is defined as a granular, refractory major portion of mixture (90 – 98% in dependence on used binder). Sand properties depend on it has chemical and mineralogical composition; mainly particle size distribution and shape of grains and its size and sand surface texture. A comparative measurement of two quartz sand with different surface quality was carried out. Greensand mixtures were prepared to measure their permeability, compressive strength and wet tensile strength. The strength of sand mixtures has two main components. One of them is the cohesion of the binder; the other one is the adhesion between the binder and the foundry sand. The aim of this research is to determine the ratio of cohesion and adhesion within the strength values.

    Emotions and moods can play a significant role in the decision making. The present paper contest this point by providing evidence on the two important approaches used in decision making that is structured decision approach and intuition. For this purpose data was gathered from 150 respondents in two different groups. Chi square test, independent sample t-test and logistic regression analysis were used to test the hypothesis. The results of the study reveal that individuals with positive and negative mood state vary significantly in their use of structured decision approach and intuition. The individuals with negative mood state are more likely to use all steps of structured decision approach as compared to the individuals in the positive mood state. The results of the study further reveal that the individual’s emotional state significantly predicted the use of structured approach and intuition in decision making.

    Since the 70's, when huge sulphidic open pits were developed, the acidic rock drainage (ARD) become the leader problem of the sulphidic mining industry. Although the recycling is an essential technology, it cannot cover the demand alone, thus mining activity needs to continue. Acidity in mine drainage commonly requires most of the attention, but the main problem is the caused elevated level of metal mobility and leaching, which are generated by the increased rates of sulphide weathering under acidic conditions. The Itos mine is a polymetallic vein deposit in Bolivia, had been mined for silver and tin until 1990, leaving behind much and huge tailings and mine waste heaps, where quite often the pyrite content exceeds 10 %. Serious ARD effects take place in the mine waste heaps. These processes can be well characterized with the pH 1 or 2 of the seepage water, which forms serious alteration in the waste itself and the neighbouring rocks. In three consecutive years, the pyrite oxidation rate was investigated on the same 7 samples by humidity cell test. 5-6 months pauses were left between the humidity cell test periods, which mimics the alternation of wet and dry periods, typical for the place. The results give much more information, than the oxidation rate in the individual test periods, showing the changes by time. This applied method gave good result to characterize the behaviour of the waste in long-term. The column test was complemented with mineralogical analyses, such as electron probe micro analysis. The mineralogical and column test analyses show, that the changes of the pyrite oxidation rate split the samples into three different groups, one where the oxidation rate decreases, second where it increases with time and the third where oxidation rate is maximal and stays stable for several years.

    Spatial visualization skills have an important role in teaching and learning of engineering studies. Many studies have shown that there are correlations between various measures of spatial skills and performance in particular Science, Technology, Engineering and Mathematics (STEM). Many engineering students have problems with solving mathematics problems, using mathematical models in practice, imagining a spatial figure and therefore to solve the spatial geometry exercises, so development of these abilities is very important. We have developed special tools and worksheets for development of engineering and innovation skills.

    The Ti-2Al-2.5Zr titanium alloy plate in beta phase water quench at different times of the reentry after annealing is implemented while primary phase number and size distribution of samples are obtained. This research is carried out on corrosion behavior in 3.5% [mass fraction] NaCl solution. Experimental study showed that after the beta phase water quenching Ti-2Al-2.5Zr titanium alloyed after 500 oC annealing when partial recrystallization happened. There seems to be lots of tiny dispersion in the alloy that was annealed with its samples of six-party [HCP] structure of Ti, Zr, Al phase 2 with the dimension below 100 nm. Reaching 500 oC when the rate of annealing at a primary phase of the sample at 550 oC is low 90% of the primary phase is less than 100 nm. The changing of the rule of present decreasing also triggers little difference overall. Precipitation in the process of annealing Zr [Nb,Fe,Cr] 2is less that proves to be good for corrosion resistance.

    Under establishment, we mean the process that results in the creation of a new unit (eg factory, plant, office, etc.), a workplace or an existing one what will be renewed, expanded or restructured, or installed; installed on a machine, plant, appliance, whether or not for productive or non-productive purposes. It is generally true that the design, construction, use and subsequent operation of workplaces, facilities, technology, materials, energy, personal protective equipment; production, distribution, import, transportation, movement, use and use of workplaces; in the absence of these, the requirements of the scientific-technical standard can be expected. An employer, operator, and service provider must adapt to market conditions. Accordingly, it should monitor the expectations of customers, business partners, market changes, trends to adapt to expectations, and therefore constantly develop their products, services, produce reliable quality, ensure that quality meets the market expectations providing personal and material conditions to ensure that employees can effectively and safely meet market expectations. The recognized business perception of the employer is to accomplish the above, the objectives to be achieved must be formulated, priority should be given to the potential risks (with particular regard to occupational safety risks) to be measured, measures to be taken to ensure effectiveness, short-, medium- and long-term planning, investment.

    Business leaders can use several strategic tools to improve the organization, depending on what they consider to be important. The Supply Chain Operational Reference Model (SCOR) is one of these. Its importance is to link business processes, performance metrics, best practices, and technology together and to create a unified structure. It promotes communication between the stakeholders of the supply chain and improves supply chain management and the efficiency of the related supply chain improvement activities. The aim of this study is to find out how the SCOR model appears in the international literature related to warehousing and performance. What methods and tools do authors use to investigate their research questions and hypotheses? Description statistics and category selection were used to present the results of the study. The number of SCOR model researches related to warehouse performance measurments are very rare, it is rather used to describe different processes. In the future, it would be worthwhile to extend the SCOR model analyzes to further fields, especially to warehouse performance measurements.

    Business organisations constantly strive to improve their processes, both internal and external. Within the supply chain of a product, different strategies can be applied. This paper aims to answer the basic questions like what is the core of lean and agile SCM strategies, what are the differences of the two models, and how can they be combined. This paper examines further, which of these SCM models and what elements of them can be applied for wood pellet supply chains, also examining the possibility of their combination. The result of these examinations is, that even though fuel pellets can be considered as simple commodity and not a very innovative product, diversity in input characteristics, optimization of fuel pellet technology process variables and changes in output market qualities and quantities need sometimes agile, flexible answer from pellet fuel SCM. The basically lean character of pellet fuel technologies and SCM can further enhanced by implementing agile SCM model elements, as is the increased integration of suppliers into the supply chain.
