The environmental policy of the European Union focuses on decreasing emission of greenhouse gases. However there is no knowledge about the effect and the operation of the environmental economic methods which could efficiently influence this process. Therefore, practical emission trade was investigated. Recently, the commerce of AUEs started to...change in Hungary, as well. Most transactions are made by a broker. Electronic commerce, which can be made with or without a broker, is spreading. The benefit of this form is that it is simple and cheap, in spite of the entrance fee of the stock exchange. This study could help to utilize carbon quotas in different types of commerce.
The subject of my study is the methodological question of one of the topics of operation research as an application field of mathematics. The mathematics and operation research team of our institute aims to provide up to date knowledge to our students of both regular and distance education courses. Each topic has been allotted to a different te...acher, thus my responsibilities include Networks and their economic application, and my ambition is to achieve increasingly good results teaching this subject. The distance education course of our college provides the opportunity to try a wide range of methodological methods.
Honey is our essential food since ancient times. In Hungary about 25 000 tons of honey are produced each year, and most of the product (80%) is exported. Hungarian honeys have excellent quality but because of scandals of honey adulteration the interest and recognition may decrease. Therefore we must elaborate a method with which the establishme...nt of adulteration is simple and cheap. In this study we concentrate on simple quality parameters which inspection is not elaborate. These parameters for example sugar- and moisture contains, proline content, electrical
conductivity, element content, pH, HMF content, degree of acidity. We examined these parameters in producers’ and commercial samples. We succeed fund parameters which characteristic of one type of honey thus we have possibility identify of honey type. For example the proline content was very low in the producers’ linden honey (mean 126 mg/kg). This value is lower than the regulation, but in case of commercial linden honey this parameter is higher than regulation. According to electrical conductivity and Potassium content is provable the type of linden honey.
Most of the enterprises operating in Hungary belong to the group of small and medium enterprises (SMEs) which means that their total number of staff is less than 250. The aim of the study is to examine SMEs operating within the North Great Plain region. It provides a short summary of the general characteristics of the region, the situation and...significance of SMEs based on the data 2009 and it also clarifies the relevant definitions. The data shows that the enterprise type that is most characteristic in the the region is joint venture (the most popular type is Ltd). It can be laid down as a fact that the number of micro and sole entrepreneurs is also significant in the area. It is also clear that the majority of small enterprises deals
with commerce, while most of the medium enterprises are involved in industry (processing industry). As a continuation of the examination, size of investments, influx of foreign capital, ratio of employed people and grant opportunities are also to be evaluated since these factors influence the operation of enterprises as well.
