Polylactic Acid as a Potential Alternatives of Traditional Plastic Packagings in Food Industry
123-129Views:523Huge quantity of synthetic polymers is used as packaging materials in different fields of food industries. A significant part of these polymers applied as a primary, direct food contact construction. The scoped application area is the sweet industry. In this field Polystyrol (PS), Polypropylene (PP) and Polyethylene terephthalate (PET) have used but during the last fifteen years the usage of PET has been grown. In one hand the price of this material is efficient, form other hand the PET is the one of the most safe (for food industrial applications) petrol chemical plastic that can be used as primary or secondary food contact packaging material. To maximize the customer safety and minimize the environmental impact of traditional PET, a new bio-sourced and bio-degradable alternative polymer aimed to be used in this special food industrial segment. One of the potential alternatives is the Polylactic acid (PLA) that would be a possible substitute as it is compostable and produced from renewable sources and has good physical and mechanical properties [1].

Építőipari kockázatok rétegei = Analysis of construction risks of layer
92-101Views:227Risk and uncertainty are subjects of philosophic and theoretic discussions long time ago. Both concepts have the intention that nature and effects of future happenings have to be analyzed and forecasted. Difference is though that analysis is possible by different means. Uncertainty is frightening and hard to be analyzed. On the other hand, risk is better served by data, easier to find a methodology that makes it a more acceptable and manageable object. Theoretic part of the article states that risk and uncertainty entitle a risk spectrum. The next statement is that this spectrum has layers piled on one on the other, from which risk and uncertainty are the ones on the sides.

Construction of Tourism Supply Chains Based on Consumer and Service Provider Responses
Views:395The tour operator wants to satisfy all the needs of those who want to travel at the highest possible level. Experiences related to planning and organizing trips are almost as important as the vacation or excursion itself. My study compares the characteristics of domestic and foreign trips based on the consumers responses. The comparison was done by the following points: time for preparations, the reservation process, getting to the selected destination, the hotel selection, or the duration of the journey. At the same time, the chain is completed with tourism service providers, whose cooperation is key to meet the needs of travellers, all in the common interest of the guest being satisfied when they return home.

Economic Analysis of Thermal Insulation Systems
1-5Views:258One of today's most important problem of inadequate energy management. In Hungary, most of the buildings considered to be outdated in the building materials used and taking into account the construction technology. A significant part of the heat energy used for heating purposes before leaving the environment through the building envelope elements used in time. In our study we investigate whether an average house how much energy you can save the facade walls with insulation.

Fraud in the Financial Sectors
1-17Views:508The competition for social resources encourages economic players to break ethical business rules to gain an economic advantage. Digitized data is making it increasingly difficult to verify their content of reality. The Wirecard scandal and the COVID-19 crisis will transform the environment around us, change our way of thinking about the world, accelerate discussions on the possible control of data produced by digitization tools, and the issue of the widest possible introduction of international accounting. Since the economic crisis of 2007, there has been a general and measurable increase in fraud in public procurements in construction industry, real estate, oil and gas, heavy industry and in mining industry, and in the financial sectors, which some governments of countries are trying to prevent it by using new tax control methods. In the stagnant economies of the economic crisis that is likely to materialize as a result of the COVID-19 epidemic, economic players will share on fewer and fewer orders, and as competition increases, the possibility or compulsion of fraud increases. Crises either begin in the financial sector or it will become one of its victims. Although financial scandals have not shaken confidence in the financial sector in recent decades, but it has violated the generally accepted public opinion that the financial sector is strictly regulated and it is non-fraudulent, non-infected area. International events affecting the financial sector have shown that internal procedures that ensure the lawful operation of a company in financial institutions have not prevented internal abuse because some of the perpetrators came from leaders.Due to the generalizations, the integrity of financial and supervisory organizations not directly involved in financial scandals are also significantly damaged, and trust can only be restored again through joint efforts, legal tightening and appropriate communication of it.
