The direct and indirect costs associated with food hypersensitivity in households: A study in the Netherlands, Poland, and Spain
107-117Views:182Background: Recent studies show that food hypersensitivity, such as food allergy or food intolerance, has the potential to affect direct, indirect and intangible economic costs experienced by individuals and their families. This research assesses the direct and indirect economic costs of food hypersensitivity at the household level in the Netherlands, Poland, and Spain.
Methods: A self-administered postal survey was conducted (n=1558). Respondents with food hypersensitivity were clinically diagnosed cases recruited through clinical centres in Poland and Spain. In the Netherlands, food hypersensitivity cases were recruited through hospitals, patient organisations and advertisements. The controls formed the baseline sample and were obtained from households in which none of the members had food hypersensitivity. The monetary value of indirect costs, forgone time, was calculated using the opportunity cost method. The indirect and direct costs were expressed in purchasing power parity. Analysis of co-variance on the cost items was used to test the within-country differences between respondents with food hypersensitivity and respondents without food hypersensitivity, as well as across the three countries.
Results: The average total direct and indirect costs across all countries for families with food hypersensitive family members are not higher than for households without food hypersensitive members. However, the intangible costs for food hypersensitive individuals appear to be higher than for individuals in the control group.
Conclusions: These results do not support the hypothesis that all food allergies incur high costs to the individual. However, being hypersensitive to foods may have a negative impact on quality of life compared to people who are not food hypersensitive. -
10 year anniversary of the Journal APSTRACT: The history of an open access journal
5-8Views:203The idea initiating the birth of the journal APSTRACT was initiated by András Nábrádi, during a 2005 AGRIMBA1 executive board meeting held in Aberdeen, UK. AGRIMBA is an open international network of academics and professionals from universities and related institutions dealing with education and research in agribusiness (Csapó et al., 2010). Currently, the Network is especially active in Central and Eastern Europe (Heijman, 2015). The main objective of the Network is to set standards based on best practices for programmes it oversees and to accredit them on the basis of these standards. The International MBA Network was established in 1995, by founding members from Wageningen University, Scottish Agricultural College, the Czech University of Life Sciences in Prague, Warsaw Agricultural University, University College Cork and the University of Wolverhampton. Between 2000 and 2009, the following universities joined the Network: Humboldt University Berlin, the University of Debrecen, Arkansas State University, the Agricultural University of Ukraine, the Timiryazev Academy in Moscow, the University of Belgrade and the University of Zagreb (Heijman, 2015). The Universities of Belgorod (Russia) and Kazan (Russia) has also joined the network last year.

ONLINE AND E-LEARNING BEST PRACTICES, NEEDS AND HABITS FOR THE INTERNATIONAL AGRIMBA NETWORK
Views:56From the literature part of this research, it shows that, some of the most popular Learning Management Systems (LMS), such as Moodle, Canvas and Blackboard, are used by many universities and colleges worldwide and their popularity is steadily increasing as more institutions adopt online learning. The usage statistics of LMSs by universities can be influenced by a number of factors, such as the size of the university, the specific requirements of the institution, the availability of alternative solutions, and the preferences of faculty and students. In addition, the popularity of LMSs among universities may change over time as new systems enter the market or as existing systems improve and evolve. Based on the number of customers, Moodle's three biggest competitors in the learning management systems category are Google Classroom with 11.70%, LinkedIn Learning with 8.87% and TalentLMS with 5.16% market share.
The most frequently used functionalities of the e-learning system are: study content creation, course management and content library, and the least frequently used are integration with other systems, multilanguage utility, plagiarism checking, accessibility to people with disabilities and personalized learning. Similarly, the most popular functionalities are course management, study content creation and assessment and testing. Respondents least liked the functions of integration with other systems, webinars, accessibility for inclusion, and video hosting and streaming.
Lectures or slides are most often uploaded to platforms, followed by written materials and links, then videos, pictures and tables. Judging by the answers received, the majority of respondents are either completely satisfied (34%) or moderately satisfied (42%) with the e-learning systems they are using now.

Opportunities for wastewater heat recovery in Hungary and its role in the circular economy
Views:357Most of the energy content of wastewater can be found in wastewater heat, however, its recovery is limited. In this article, the current situation, future opportunities of wastewater heat recovery are presented based on secondary data collection, mentioning the constraints and main influencing factors of sustainable implementation of heat recovery systems in Hungary. Besides, the already existing systems are described. As regards the capacities of treatment plants, 103 of the 574 domestic plants have a capacity of over 20,000 Population Equivalent (PE), of which 25 plants have a capacity of over 100,000 PE. According to our calculations, in big cities/capitals (20.000 – 100.000, and over 100.000 inhabitants), it may be possible to recover wastewater heat sustainably in several places. In small towns (5.000 – 20.000 inhabitants), wastewater heat recovery can be technologically and economically sustainable only in the presence of agricultural or industrial plants with high and continuous wastewater feed into the pipeline system. Taking into account the temperature conditions at each place of use and their estimated fluctuations, it can be said that proper, careful planning, sizing and implementation have a crucial effect on the efficiency of microbiological activity in the treatment plants. In bigger cities, of course, the effect of the temperature drop of one main collector may be minimal, however, in smaller and medium-sized settlements, excessive heat extraction may result in complete inhibition or cessation of nitrification. In Hungarian case studies, the maximum acceptable temperature drop is approx. 2-3 °C. It can be stated that energy recovery from wastewater may be very promising considering the size and temperature limitations. Therefore, the rational recovery of wastewater heat can be an important part of the implementation of circular economy and sustainable energy utilization in wastewater management, resulting in significant energy savings and pollutant reduction.

Medals and degrees: factors influencing dual career of elite student athletes at the University of Debrecen
93-98Views:179Career planning and goal setting play a significant role in the life of elite athletes gaining critical relevance during the overlapping years with university studies. As athletic career contain a necessary end and cannot serve as a profession for life, all athletes shall go through modification period in their professional lives. The athletic career shall come to an end and elite athletes need to find another profession for which they need to prepare as well. The specialities of this undertake is that the peak or the progressive cycle of athletic career often times overlap in time with high school and university studies. This definitely challenges those young athletes who made the decision to continue their studies at the university level beside their athletic careers. The objective of this study is to explore the main factors influencing the simultaneous realisation of studies and elite sport careers during university years. Part of a complex research approach on dual career in sport this study is aimed to gain information about methods of athletes for managing their dual tasks, the perceived relationship of student athletes to their peers, teachers and coaches, and their position on the relevant policy regulations provided by the university environment. Following the development of research instruments, data collection was conducted by focus-group interviews at the University of Debrecen among student elite athletes receiving sport scholarships (N=15). Level of success in sport, sport type (individual and team) and gender distribution was taking into account. The results shall contribute to the development of a future research instrument in a form of a questionnaire to assess aspects of dual career of athletes in case of larger samples.

An ICT-based traceability system in compound feed industry
59-64Views:179The term traceability refers to recording of flow of products along the food chain from production to consumption with inclusion of all intermediate applications involved in processing/packaging stages. The aim for establishing traceability in the food chain is to provide the timely identification and recall of batches of product from the market when a risk threatens the health of consumers. Since compound feed products are basic inputs in livestock and poultry production, ICT-based feed traceability systems can be considered as a initial step in food traceability management. These systems are simply information recording systems that are designed to trace and track the flow and characteristics of animal feed along the feed supply chain. This paper describes the architecture and some functional properties of a feed traceability system called as the “feed TRace”, focusing particularly on compound feed and integrated poultry meat industries. The feedTRace aims to improve compound feed supply chain management, to increase feed safety and quality control, and to gain marketing competencies with traceable products in compound feed industry. The system is currently under beta stage, and is tested in two high capacity feed milling plants and an integrated broiler company located inAdana province of Turkey.

Synthetic biology applied in the agrifood sector: Societal priorities and pitfalls
89-95Views:258Synthetic biology offers potential for innovation in the agrifood sector, although concerns have been raised consumer rejection of applications will occur similar to that associated with the introduction of genetically modified foods. Risk-benefit assessment should address socio-economic, as well as health and environmental impacts. Ethical issues may be of particular relevance to the application synthetic biology, and may also resonate with societal concerns. A case-by-case analysis of relevant issues may be needed, and innovation must be driven by societal and consumer preferences as well as technological possibilities. Research into consumer and societal priorities is required early in the innovation trajectory.

Assessing the financial viability of the floricultural industry in Ghana
119-126Views:164This study determines the financial viability of the floricultural industry in Ghana using both discounting and non-discounting investment appraisal methods. The feasibility analysis suggests that large-scale floricultural firms are more profitable particularly with the production of cut flowers. However, investors with limited capital can venture into small-scale production specifically cut flowers. The conclusion is that the floriculture industry is financially viable therefore investors are encouraged to expend their resources in the industry. We recommend that the government and stakeholders need to create institutional support to enable the already established firms to further develop and attract new investors in the sector.

The connection between academic and athletic performance among elite university student athletes
19-26Views:435Athletes in higher education are not only expected to produce high level performance but to find the balance between the preparation for post-athletic life and the requirements of the university. The objective of this study is to explore the connections between academic performance and level of sport. Also, to elaborate on the role of relevant policy regulations and institutional support that help elite athletes meet academic requirements. Data collection was conducted by means of online questionnaires involving athletes receiving sport scholarships at the University of Debrecen (N=159). The data from questionnaires were processed by using SPSS 18. Version software. For data analyse four groups were extracted based on level of sport performance and involvement: international elite, division I, division II, division III. The results indicate that the academic performance on the two international elite of sport did not differ from the average, and that these athletes did not experience any difficulties earning course credits at the university while being engaged in doing sport. In most cases, elite athletes did not apply for the various kind of support instruments, thus, they are able to balance athletic preparation and academic requirements without supportive modifications of university policies. The results also shed light on the fact that the academic performance does not only depend on the level of sport and the chosen major at the university, but it is also influenced by the time devoted to study and training, and the sport type (individual or team sport). There are differences observed between athletes participating in individual or team sport concerning the general average of grades, the effectiveness of earning credits, the number of weekly training, as well as the time devoted to training in preparatory and competitive periods. According to the results, the various amount of time devoted to study or sport does not necessarily result in academic performance decline. In addition, results support that athletes do keep academic studies rather important and they are aware that university years are considered to be a significant period in preparation for post-athletic life.

Innovative training methods in business higher education
75-78Views:154A unique business-oriented educational method was launched in 2010 at the University Of Debrecen, Hungary, in the Faculty Of Applied Economics and Rural Development; the method has existed in the JAMK University of Applied Science in Jyväskylä (Finland) since 1993, and is called Team Academy. The gist of this training is that the students learn entrepreneurship through their ‘living’ organisations with the application of the principle ‘learning-by-doing’. Besides developing the students’ entrepreneurial competencies and skills, this educational model also offers team coaching tools to develop teams of 12-13 students that can cooperate in an efficient way. The key point of Team Academy, which has been launched in several European higher education institutes over the past years (e.g. Spain, France, the Netherlands, etc.), is that the most efficient way of learning how to operate a successful company is to learn it in practice. During the professional and project trainings, the cooperation of the team and their company’s efficiency is continuously developing with the help of team coaches. A quite wide variety of team coaching tools is used in this system, e.g. 360◦ evaluation, which is a very important tool of human resource management. Feedback from students also plays an important role in developing team cooperation; the professional frame for this is also given by the above-mentioned methodology. This method is used successfully at the Debrecen Team Academy which / and (do you mean that the a) Team Academy or b) the above-mentioned methodology will be presented? If B), then write ‘and’ instead of ‘which’) will be presented in this study. A database of 150 questionnaires is analysed through qualitative research methods.

Economic analysis of some agrotechnical factors in maize production - a Hungarian case study
5-16Views:383This paper focuses on the economic and statistical evaluation of the production technology findings of the polyfactorial maize production experiments carried out between 2015-2017 at the Látókép Experiment Site of the University of Debrecen, Faculty of Agricultural and Food Sciences and Environmental Management. The examined agrotechnical factors included irrigation, previous crop, tillage, crop density, hybrid and N nutrient supply, while the effect of different crop years was taken into consideration. In addition to descriptive statistical methods, we used multivariate regression analysis during the statistical evaluation. In the course of the evaluation, we examined three models that differed in terms of tillage methods and the consideration of crop year. In our best fit model, the factors were 71% responsible for the change in yield value. We carried out efficiency and comparative analyses in the course of the economic evaluation.
Averaged over the three examined years, it can be stated that nutrient supply and crop year had an outstanding effect on yield, while irrigation had a minimal effect. However, global warming may justify irrigation in the future, not only from a biological point of view, but also from an economic aspect.
Ideal tillage is also greatly affected by crop year, too. Altogether, of the examined tillage systems, subsoiling proved to be the best from an economic point of view.
Our investigations confirm that it is better to perform intensive farming under more favourable market conditions. The optimum of N fertilisation is probably outside of the range we examined, if the extreme changes in maize and fertiliser prices are ignored.JEL Classification: Q16, Q12, Q13, O32

Learning Motivations, Styles and Expectations of Students – a Survey at the University of Debrecen
41-46Views:203Based on the experience of the authors, today's university students have different learning habits, expectations of learning and knowledge compared to previous generations. This raises the question of how traditional teaching, teaching methods effectively suited to their development. In this study, the authors examined with quantitative method the expectations of bachelor and master students concerning the business education at university. The survey was conducted among university students assessing whether students with different BSc/BA or MSc/MA majors show the willingness to continue their studies, and the authors were interested in their expectations concerning the business higher education. The authors also tried to find answers in the survey how well-prepared the students feel for the offered opportunities by today's market environment, or may prefer proceeding with their studies. Among the issues authors searched what are the most effective ways of learning for them, based on learning style, what motivates them to continue learning. What kind of education form is preferred by them to continue studying? They also respond the need of having theoretical and practical knowledge and the importance of developing practical life skills. In addition, it has also been surveyed what other expectations the students have in continuing their studies with regard to the institutions. The authors of this paper are working as team coaches at the Team Academy Debrecen.

Efficiency indicators in different dimension
7-22Views:157There are several variations of efficiency definitions and of course ratios concerned with efficiency. A better understanding of the notion of efficiency is critical to dissolve ambiguity about it. Many confuse efficiency with other supposedly synonymous notions such as profitability, successfulness, competitiveness, liquidity or productivity. This ambiguity originates not only in subjective reasons, but the lack of hierarchical order among certain ideas. The primary driver in our research is, to systematize efficiency in general, and formulate a new categorical approach of the efficiency in corporate level.

An investigation on the international tourists’ expenditures in Thailand: a modelling approach
15-18Views:116As a result of the increase in both the international tourists’ expenditures and tourist arrivals to Thailand, there is a growing interest in determining the trend of international tourists’ expenditures based on time-series modelling. In our article secondary data were used to produce forecasts of the international tourists’ expenditures in Thailand between 2009 and 2010. The forecasting method is based on the ARFIMAX (0, 0.197, 0, 0.033) model. Furthermore, this method predicted that international tourists’ expenditures in Thailand between 2009 and 2010 will have to contract and slow down. This paper seeks to determine whether the international tourists’ expenditures are affected by other circumstances. The results of this study revealed that the international tourist arrivals to Thailand will also have to slow down. However, from the results, there is solid evidence to support such a claim.

Coach education approach in 16 Hungarian sport federations results of the first sport organizational audit
87-91Views:151Nowadays the Hungarian government finances the sports in many ways; one of these grant forms is the group of 16 prioritized sports (biking, boxing, fencing, gymnastic, judo, track and field, kayak-canoeing, modern pentathlon, rowing, shooting, skating, swimming, tennis, table tennis, volleyball and wrestling) which are supported notably by the Hungarian Olympic Committee (HOC) till 2020. The purpose of the 1st sport vocational audit was to identify the current status of these sports, and also to create a database in many fields as a benchmark of the development. The sport management department of the Semmelweis University, Faculty of Physical Education and Sport Sciences (TF) contracted with the Hungarian Olympic Committee (HOC) in order to carry the sport vocational audit out. A sport develops if the numbers of the athletes grow or the results of the national teams are better. The coaches are the key persons in this development, if they could gather more children into the sport or they work better with the elite athletes the development has already done. It was examined the existence of the coach education programs; all the federations were running coaching programs for adults (OKJ) in both levels (coach assistant, coach). By 14 associations existed the first level of the higher education coaching program (BSc) and in 13 federations operated the MSc coaching program as well. All these coaching courses were common programs with schools, or universities. It was no evidence found that the federations run own coaching program but coaching license system existed in two sports at the time of the investigation.

International outlook: The notes and business report in the frame of financial reporting
155-165Views:162Are the accounting reports to be prepared on a yearly basis suitable for indicating problems, possibly for informing the stakeholders about the declining phase of an enterprise? The information needs of the various market operators are different thus the question is whether the management of an enterprise or possibly the owners place an emphasis on the adequate information. We examine the issue of social responsibility from a special approach in which, in addition to the corporate lifecycle models, there is a focus on the information content of the Hungarian and international accounting reports, moreover the content of the further report that is to be prepared but does not form a part of the accounting report. The aim of our research is to compare the notes and the further reports which meet the Hungarian, Rumanian, Slovakian and international standards and corroborate the quantitative data of the accounting report. By paralleling the notes and the further reports, we draw attention to the fact that one of the most important accounting principles i.e. the going concern concept, which the other principles are based on, will be (or will likely be) affected insofar as content of the enterprises’ reports does not comply with the legislation. In addition to the addressees of accounting, the authors point at the issue of social responsibility based on those similarities which can be observed in the relations of the value-oriented corporate governance.

Somatic development and some motor performances of young girls based on age and birth season
117-123Views:119There are numerous publications in the literature reporting physical development and motor performances of children of different ages based on sex and various environmental factors. However, there are not many publications on the birth season effect. The aim of the study was to evaluate the differences among children in physical development and motor performances based on age and birth season. Physical development described by body height and body weight, in addition to motor performance indicators including the twenty-metre dash, standing broad jump, six minutes of continuous running, throwing with a stuffed ball, and obstacle race-tests were studied. The survey included the participation of 426 girls. From the group the seven-, eight-, and nine-year olds numbered 148, 191, and 87 respectively. The group of girls who were born in winter, spring, summer and autumn numbered 114, 110, 89 and119 respectively. The tested data were evaluated with unitrate analyses of variance using SPSS statistical package. Mean value, standard error, standard deviation and coefficient of variation were calculated. The significance of differences between mean values was evaluated using “t” test. Differences with an error below 5% were considered to be significant. Furthermore, a correlation analysis was used to evaluate the relationship between season of birth, body development and motor-related performance data. Age, body height, body weight, throwing a stuffed ball in one hand, twenty-metre dash, six minutes of continuous running, and obstacle race-test are interdependent variables of development and motor performances of young girls of this age. Data from the study results show that the children group included in the tests was quite homogenous in body height, but heterogeneous in body weight and motor performances. Physical development and four of the five evaluated sport skills were affected by the birth season. Development and motor performances of the summer- and autumn-born girls are generally better than those born in winter or spring. Differences are significant except for the obstacle race-test. Age, body height, body weight, throwing with a stuffed ball in one hand, twentymetre dash, six minutes of continuous running, and the obstacle race-test seem to be interdependent variables of development and motor performances of young girls of this age.

Comparison of the performance of a trained and an untrained sensory panel on sweetcorn varieties with the panelcheck software
77-83Views:557In this paper the results of trained and untrained sensory panels are compared on five Hungarian commercial sweet corn samples. The two evaluations were carried out in a sensory laboratory (ISO 6658:2005), with the same experimental design, with two replicates, and the panels consisted of 10 panelists. In both cases the panels assembled the profiles of the samples according to the vocabulary chosen by the trained panelists. The results show that the untrained panel has higher standard deviation, weaker repeatability and less significant parameters (ISO/DIS 11132). However 10 of the 17 sensory attributes were significant in the case of the untrained panel, the trained panel has 15 significant parameters with lower standard deviation and good repeatability. During the statistical investigation we focused on the panel performance and used the PanelCheck open source software package to achieve this goal. We followed the workflow suggested by the researchers of the Nofima, the developers of the PanelCheck. According to the examined parameters the trained panel has better discrimination ability (F values) for attributes ’yellow color’, ’hue’, roughness’, ’freshness’, ’juiciness’, ’tenderness’. There was not an attribute evaluated by the untrained panel where all the panel members reached the line representing the 5% significance level. Furthermore the trained panel has better agreement between its assessors (Tucker-1 plots) and the repeatability is much better according to the MSE plots. This examination confirms that it is necessary to train the panels in order to get reliable and consistent results.
