Consuming fresh blueberries has many health benefits due to the extremely high level of phytonutrients. During storage, the berries spoil due to microbial contamination. The aim of the work was to investigate the effect of pullulan coating containing 5% and 10% propolis extract on reducing the number of bacteria and mould and on the physicochemical properties of coated blueberries during storage. The results showed that the count of microorganisms was reduced by 3–4.5 logarithmic cycle after 21 days (16°C, RH of 58–63%). It was also found that coatings delayed blueberry ripening as well as decreased weight loss. During storage, minor increase were found in titratable acidity values and no change the total soluble solid values in blueberries covered with pullulan coating containing propolis extract in comparison with the uncoated ones. Thus, the pullulan coating with propolis extract has the potential as microbiological protection for blueberry fruit.

Background: The subject of the paper is pro-health behaviour of women (N=477) who have children (N=124) and those who have no children (N=353). The Theory of Planned Behaviour (TPB) by Icek Ajzen, in the light of which the differences in the health behaviour level of the sample group are considered, constitutes the theoretical basis of this work. Material/Methods: The research group consisted of women at the age of 19-36 (M=27,5 yrs of age SD=4 yrs of age). The Health and Behaviour Survey Questionnaire by Steptoe and Wardle was used for the measurement. Four scales of healthy behaviour values, i.e., taking up physical activity, avoiding addictions, hygienic and medical behaviour and nutritional habits were analysed. Results: As a result of the comparison, it appears that childless women demonstrated a significantly higher physical activity level (M=263.03) compared to women who have children (M=170.58) at the significance level (p=0.001). As far as the hygienic and medical behaviour is concerned, a significantly higher level was observed in the group of women who have children (M=261.15) than in the group of childless women (M=231.22) at the significance level (p=0.037). Conclusions: Further research should focus on the determination of the influence of subjective norm change (knowledge) on the health activities undertaken by women.

This paper deals with determinants of physical fitness and of a value system of the Polish Handball Federation's [Polski Związek Piłki Ręcznej] referees (N=61). The reference group theory describing the transfer of a value system within a group of referees constitutes the theoretical foundation of the paper. The referees' age ranged from 19 to 59 years (M=30.56 years SD=7.16 years). The measurement was carried out by means of the Scheler Values Scale constructed by Piotr Brzozowski and the Questionnaire of Ethics constructed by Wiesław Baryła and Bogdan Wojciszke. The results of the six basic hierarchies of values were analysed: sanctity, hedonistic, vital, aesthetic, truth, and moral. Comparisons of data obtained from a group of referees preferring common good ethics with referees showing low acceptance of the common good ethics have not revealed a considerably higher acceptance rate only in the case of values of truth and aesthetics values. The remaining hierarchies demonstrated considerable statistical variance. Further research on the determinants of referees' moral behaviours should focus on determining the impact of the subject's sex and a change in temperament traits on the development of a refereeing career.
