KOSTKOVÁ, Miroslava January 2011 (has links)
The paper studied the structure of meals in selected restaurants in the Czech Republic and compared with selected Austrian catering facilities. The analysis shows that Austria is against the Czech Republic ahead of not only the quantity used in organic food, but also in the knowledge that is related to organic food. And not just in public catering facilities, but also in households. In the questionnaire survey was to determine knowledge about organic foods, the principles under which they were prepared, where you can buy at what price range varies. About the quality of organic food, people's interest in organic food, organic food as often used in homes both Czech and Austrian. Were also detected in the possibilities of school catering facilities, the reasons why organic food is often used and more. All of this was examined children's nursery school, primary school pupils and college students and executives interviewed kitchen. The result is that in the Czech Republic are used almost exclusively organic foods at home and rarely. While in the kitchens of school facilities for them is great interest either from the kitchen diners and employees. By contrast, in Austria, organic food is commonly used both in households and in public catering facilities and thein use is considered an asset. SWOT analysis derived from several sources provided by the Ministry of Agriculture, shows the appropriateness of inclusion of organic food to offer menus. Understanding the concept of organic food is gradually increasing, from our survey suggests that this concept students know 72% and 75% of staff kitchen. In Austria, this question knew the answer 100% of the respondents. 13% of respondents would welcome the offer of meals of organic foods in their cafeterias, dining halls in the Austrian would appreciate higher proportion of organic food. 60% of students in the questionnaire said that they can byu organic food in supermarkets, while in Austria prevails buy organic food directly on the farm. Most in the Czech Republic to sign purchase organic fruits and vegetables, in second place as milk and dairy products. In contrast to Austria, where most purchases organic milk and dairy products, fruit in second place and third place is vegetables.

Ekologinio ūkininkavimo veiksnių modeliavimas / Modelling the determinants of Organic Farming

Skulskis, Virgilijus 07 October 2010 (has links)
Disertacijos tikslas yra ekologiškai ūkininkaujančiuosius suklasifikavus pagal jų skirtingus veiklos prioritetus, nustatyti veiksnių reikšmingumą ekologinio ūkininkavimo vystymui. Tai pasiekta išanalizavus sistemų teorijos, ekologinio ūkininkavimo, darnaus žemės ūkio vystymosi ir kaimo plėtros, aplinkosaugos, maisto kokybės bei saugos ir motyvacijos teorijos krypčių perspektyvas, identifikavus ekologinio ūkininkavimo veiksnius, atlikus empirinių tyrimų modelių ir jų pritaikomumo Lietuvos kontekstui analizę. Sukurtas ir empiriniu tyrimu patikrintas ekologinio ūkininkavimo veiksnių vertinimo teorinis modelis leido nustatyti veiksnių reikšmingumą strateginiam ūkininkų sprendimui dėl ekologės gamybos būdo plėtotės pagal dvi veiklos prioritetų požiūriu homogeniškas ekologiškai ūkininkaujančiųjų respondentų grupes (orientuotų į pelno didinimą ir į ekologinę gyvenseną). Disertacijos rezultatai suteikia naujų žinių apie ekologinį ūkininkavimą lemiančius veiksnius, leidžia sistemiškiau nei iki šiol vertinti ekologinio ūkininkavimo veiksnius. Tyrimo rezultatai gali būti pagrindas ekologinio žemės ūkio (siaurąja prasme) ir žemės ūkio darnaus vystymosi (plačiąja prasme) racionalios politikos formavimui Lietuvoje ir kitose naujosiose Europos Sąjungos šalyse, o konkretiems ūkininkams, ypač besiruošiantiems priimti strateginius sprendimus dėl ekologinio ūkininkavimo, suteikia naujų žinių. / The dissertation aim is to assess the significance of the determinants of organic farming to its development when the respondents are classified by priority of their activity. This has been achieved through the analysis of trends and perspectives of the system theory, organic farming, sustainable development of agriculture, rural development, protection of the environment, food quality and safety and the motivation theory while identifying the determinants of organic farming, and through the analysis of empiric models and their applicability in the context of Lithuania. The established and empirically tested theoretical research model for the modelling the determinants of organic farming enabled to assess the significance of the determinants to the strategic farmers’ decision whether or not to undertake the practice of organic farming according to two homogenous groups of organic respondents depending on the activity priorities (profit-oriented and organic-oriented lifestyle). The dissertation provides with new knowledge about organic farming and enables to assess the factors of organic farming more systematically than before, the research results could be a basis for the rational policy-making in the development of organic agriculture (in a narrow sense) and sustainable agriculture (in a broad sense) in Lithuania and other new countries of the European Union, and provide with new knowledge the farmers, especially those who are preparing to make the strategic decisions...
