Megjegyzések:	Magyarország energiagazdálkodásában az elmúlt 15 évben olyan változások következtek be, amelyekkel azért érdemes foglalkozni, mivel a hazai energiatermelés mellett nagy részarányú a külföldről behozott energia is. A hazai villamos energiát főleg az atomerőmű és a fosszilis tüzelésű erőművek termelik. A rendszerváltás körül kialakult politikai változások hatással voltak az energiaszektorra is, mivel mind az energiatermelés, mind a -behozatal valamilyen szinten lecsökkent. A 2016. évi állapotokat tekintve hazánk energiatermelési összetételében nagy részarányt tesz ki a fosszilis (szén és szénhidrogének) erőforrások felhasználása. Cikkünkben az elmúlt 15 évben bekövetkezett változásokat vizsgáltuk meg az energiaszektorban. Külön figyelmet szenteltünk a kis- és nagyerőművek termelésének vizsgálatának, a magyar energiatermelés szerkezetének áttekintésére, valamint előrejelzéseket készítettünk mozgóátlag és polinomiális trendfüggvény alapján.

Megjegyzések:	The aim of energy management is to provide good quality and proper quantity energy in an economic and continuous way for the energy consumers in different parts of the country with minimal energy costs. We did our calculations because many changes happened during the last 15 years in the energy management of Romania. Year by year the percent of the import energy is increasing. Most of the energy is produced by nuclear, hydro and thermal plants. Looking at the year 2016 in the energy production of Romania the most dominant is the coal and gas usage to produce electric energy in thermal plants. In this paper we wanted to look through the energy management of Romania both in the field of conventional and renewable energy sources based on different aspects. In our research we have made several forecasts considering the consumption and production. In this paper we have reviewed the Romanian energy management from 2000 until recently, since a continuous change can be seen in the energy management of Romania. In the analysis descriptive statistics, dynamic indices and polynomial trend values were used. At the calculations many databases were taken into consideration. For some of the analysis we used the data found on Transelectrica. Besides, we used the data of BP Statistical Review of World Energy and their descriptions. In case of Romania we also utilized the governmental strategies, professional political materials, action plans and different professional studies as well. In the course of our research we used long time series in which the component effect of the time series must be filtered out, so it had to be ♭smoothened'. There are two methods for this: the method of moving averages and the analytical trend calculation. We chose the analytical trend calculations (polynomial trend function) based on the proper fitting.

Cím:	Formation of migration potencial in Hungary from 2000 until today / Csipkés Margit, Nagy Sándor
Dátum:	2017
ISSN:	1222-569X 1582-5450
Megjegyzések:	When hearing international migration we can think of two things. One is the emigration process while the other is the wave of refugees. In our study we examined the changes of the number of employees emigrating from Hungary from 2000 until today. Examining the migration potential can be viewed as a very important topic nowadays in Hungary, since the rate of Hungarian emigrants started to grow after 2006 and the rate of growth got faster after 2010. The reason of fastening was the opening of the Austrian and German labor market. The actuality of the topic lays in the fact that international emigration melts the labor market's processes, influences the given country's employment level, moreover it has an influencing role on the rate of wages. Emigration from the given state can have several reasons: natural damage, war, marginalization, economic reasons, etc. In our study we examine emigration caused by economic reasons. We have to take into consideration that measuring emigration is hard in every country (in this way, in Hungary as well), due to the deficiency of data. The reason of deficiency is that those who leave for abroad often forgot to report their leaving for abroad. The reason of this is that from March 1, 2013, only the permanent foreign settlement should be reported towards the administration (District Office, Consulate). Earlier, the temporary (more than 3 months) settlement was also obligatory to be reported Many leaving Hungarian forgets that that working on abroad for more than 3 months should be reported in every case towards Social Insurance organizations and Tax Authorities. That is why we emphasize that the introduction of migration potential made by us does not show any direct correlation with the actual migration, however, with the help of this study, the expected measure of moving could be recognized along with the expected composition of emigrants.

I would like to emphasise that my migration potential presentation does not show a direct correlation with the actual migration. However, this study might show the expected movement rates and the composition of emigrants.
