Comparison of the performance of a trained and an untrained sensory panel on sweetcorn varieties with the panelcheck software
77-83Views:713In 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.

The analysis of costumer satisfaction in recreational tourism
57-61Views:235Due to increased health awareness and the growing amount of assistance to boost it, health tourism research has gained significance in our days. The present study focuses on the analysis of customer needs for recreational tourism and their habits; moreover, it interviews the guests of 15 Hungarian wellness hotels through a questionnaire survey. Next we attempt to explore the rate of guest satisfaction with healthpreservation services. The study presents the findings of this research activity until now, whereas the results of further data processing will be published in the future.

Estimating the economic potential of rural microregions
71-79Views:127Experts have been involved in the problems of determining microregions in Hungary since their establishment. In Hungary, the microregions (NUTS17 IV) were established by top-down method. This system cut through existing economic and cultural connections. The villages set up their own bottom-up microregions, which have tighter connections than the official regions. In my article, I estimate the economic potential of two regions, the regions Erdôspuszta (Hungary) and Hohenlohe (Germany), after analyzing the relevant literature on determining economic potential. Projects realized by enterprises and civil organizations have strategic significance in the economies of settlements, and it is true that their developers are not members of the formal management of the settlement. The local governments, however, should conduct realization and topdown of projects, and they have to have an image of the future and strategic plans. The present Hungarian practice, which appears in supply oriented applications, is not expedient over the long-run.The projects of settlements are run parallel to each other; they therefore fail to reach any synergic effect. The aim is harmonizing and building projects onto each other.

Somatic development and some motor performances of young girls based on age and birth season
117-123Views:164There 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.
