    In this study, we have dealt with the calculation methods of the eigenfrequencies associated with the bending vibrations of rectangular-shaped beams clamped at both ends. Said eigenfrequencies were determined analytically in the single-degree of freedom model of the beam and the case of the three-dimensional solid and three-dimensional rod models by finite element modal vibration analysis. We presented the calculation method of the characteristics of the analytical model and then calculated the eigenfrequency for a concrete example. We have described the concept of modal characteristics, and in the following, we have determined its natural frequency based on the solid-beam and rod models of the former beam. We calculated and compared the solutions belonging to the models recorded in different ways in 11 additional cases of the presented methods.

  • Sportcivil szervezetek – számok a támogatások növekedése mögött

    A KSH adatgyűjtési tevékenységének köszönhetően a nonprofit szervezetekre vonatkozó átfogó adatok mind adatbázis, mind tájékoztató formájában elérhetőek. A gazdasági adatok között feltűnik az az évről-évre hasonló nagyságú, domináns támogatási részesedés. Különös tekintettel a klasszikus civil szervezetekre ez egyértelműen jelzi azt, hogy a szféra támogatáskitett és támogatásfüggő. Ezek a szervezetek ugyanis kimondottan alkalmasak támogatások fogadására. Tanulmányunkban szeretnénk másodelemzés révén rávilágítani arra, hogy a sporttal foglalkozó civil szervezetek/sportcivil szervezetek száma milyen összefüggésben van a támogatásokkal, különös tekintettel két specifikus támogatási formára, a NEA-ra és a TAO-ra vonatkozóan. Az eredmények arra utalnak, hogy van összefüggés a támogatások összegének növekedése és a sportcivil szervezetek számbeli növekedése között, és ez kifejezetten igaz az egyik legrégebbi és legújabb támogatási forma esetében is.

  • Sports Civic Organizations-Subsidies and the Subsidy Exposure

    When we discuss the topic of civic organizations, especially sports profile civic organizations we need to note and comment that issue how these organizational forms are able and capable to accept subsidies. The related data of the Central Statistical Office (KSH) highlight the phenomenon that incomes of the classic civic organizations are mainly composed of state or private source donations. Although there is a really and pretty predictable subsidy system in the field of civic sphere currently, from one hand the distribution of the single subsidy forms considerably vary, on the other hand it result in the considerable amount of available financial resources. The fact whether subsidy forms and subsidy incomes have relationship with the addition alvariables of the organizational operation, such as subsidies provided, employment relationship, and expenditures may acquire special attention at the management of organizational operation together with the planned strategic interventions in the field of the civic sphere.

    Additive manufacturing (AM) is a cutting-edge production method, which has come a long way since its first introduction in the ’80s. Back in the days its usage was very limited to stereolithography, and was only able to make weak structures, so it only worked for visualization. Four decades later it is one of the leading research fields in production areas, because of its flexibility and its ability to make almost any complex geometry. However, no matter how powerful it is, it is not omnipotent, there are certain size and shape restrictions even this method must apply to.

    High Pressure Die Casting (HPDC) is still the most productive metal-casting method of our time, however the more demanding are the industrial expectations, the more challenging it becomes to ensure the creation of the difficult cavity geometries and the thermal balance of the die-cast tool. New perspective is required, thus we can utilize high heat-conductivity tool steels and additive manufacturing technology.

  • The Relationship Between Sports Civic Organizations and Human Resources

    Every spring the Hungarian Central Statistical Office records through its ELEKTRA database system the human and economic related operation data of the past year of civic organizations. This data source is usually considered as a standard at the evaluation of the domestic civic sphere. Still, the available handout titled “Most important features of the non-profit sector”, applying mainly descriptive statistics only provides a brief picture of specifications of the sector. Parallel with it, its background database is available yearly, which provides a unique possibility for a researcher to perform secondary analysis aiming to reveal deeper relationship. The objective of our study is purely to reveal a minor part of this considerable field, the relationship between subsidies and human resources mainly due to the fact, that human resource in this sector is composed of employees and volunteers, and it is questionable whether subsidies have an impact on employment.  Results revealed that there is a relationship between human resources and subsidies, where mainly private nature subsidies have a strong impact equally on voluntariness and work related employment
