Opis:
The aim of the study is to compare price competitiveness in Poland and Lithuania based on selected food products and catering services. Special attention was paid to selected parameters characterizing both countries and retail prices of products available under specific brands in selected retail outlets. Secondary and primary studies were carried out for the purpose of the research. Empirical research in the field of price competitiveness of selected food products and catering services was carried out in Poland and Lithuania in May and June of the current year. As a hypermarket, Carrefour was selected in Poland, while in Lithuania – Maxima, and as a supermarket, Carrefour Express (Poland) and IKI (Lithuania). The selection of these stores was made on the basis of retail trade reports in Poland and Lithuania presenting the largest retail chains. Based on our research, it can be pointed out that the products available on the Polish market were mostly characterized by lower prices compared to products present on the Lithuanian market. This indicates their greater price competitiveness.
Celem opracowania jest porównanie konkurencyjności cenowej w Polsce i na Litwie bazując na cenach wybranych produktów żywnościowych i usług gastronomicznych. Szczególną uwagę zwrócono na wskaźniki charakteryzujące oba kraje oraz ceny detaliczne produktów żywnościowych dostępne pod markami w wybranych sieciach detalicznych. Dla realizacji celu badawczego przeprowadzono badania wtórne i pierwotne. Badania pierwotne w zakresie konkurencyjności cenowej wybranych produktów żywnościowych i usług gastronomicznych przeprowadzono w Polsce i na Litwie w maju i czerwcu 2019 roku. Jako hipermarket w Polsce wybrano Carrefour, na Litwie – Maxima, natomiast jako supermarket – w Polsce Carrefour Express i IKI na Litwie. Wyboru sklepów dokonano na podstawie raportów handlu detalicznego w Polsce i na Litwie prezentujących największe sieci detaliczne. Bazując na przeprowadzonych badaniach należy wskazać, że produkty dostępne na polskim rynku charakteryzują się niższymi cenami w porównaniu do produktów dostępnych na rynku litewskim. To wskazuje na większą konkurencyjność cenową polskich produktów.

Introduction: Nutrition is one of the most essential factors conditioning normal human growth and development. Nutritional errors can be the basis for the emergence and development of obesity, hypertension, atherosclerosis, osteoporosis or postural defects. Purpose: The study aimed to learn about the dietary habits of urban high-school youth. Materials and methods: The study was conducted using the original questionnaire in 2013 and covered 200 students of randomly selected high schools. Results: Among the subjects, 70.8% consumed 4 or 5 meals during the day. The boys have eaten five meals significantly more often during the day than girls. The first breakfast was consumed by 76.5% of students and the second breakfast with 69.7%. Of the subjects, 80% indicated the eating between meals. The girls preferred sweets, fruit, and sandwiches, and the boys had sandwiches, sweets, and dairy drinks. The highest percentage of the examined youth ate sweets 3-4 times a week (41.6% girls and 35.6% boys). The respondents who consumed fast food once a week constituted of 60.9% of girls and 48.7% of boys. The girls consumed sweetened drinks most often once a week, and boys 3-4 times a week. Conclusions: Nutritional errors of adolescents consisted of irregular consumption of meals, late time of the last meal before bedtime, consumption of a large number of sweet and spicy snacks and sweetened beverages were found. Wrong nutrition concerned both girls and boys

Background. The effects of a two-year educational Programme “Keep Balance” addressed to children and adolescents have been evaluated. Its purpose has been to implement the rules of proper nutrition and increasing the level of physical activity on the population level. Objective. The main objective of the evaluation was an indication if, after two years of programme activities, outcome indicators have been achieved. Material and methods. Approximately 400,000 pupils/students from 1600 educational units from the territory of the whole country have been included in the education programme. The efficiency evaluation has been carried out in a sample of n = 1506 pupils/students in the interventional group and n = 1589 in the control group. Education has been addressed to the entire school environment, pupils, students, parents, teachers, headmasters, and the local community. The survey methodology, body weight and height measurements, the BMI index, and EUROFIT physical fitness tests have been used to assess the effects of the education programme in the scope of knowledge and nutritional behaviour regarding physical activity. There were assumed outcome indicators. The certification of schools/kindergartens with “The Certificate of a School/Kindergarten Friendly to Nutrition and Physical Activity” has been used to evaluate the activation of school environments. Results. There was an improvement achieved over the assumed target points in the level of knowledge of pupils/students in the scope of nutrition and the role of physical activity, in the changes of nutritional habits, and in the results of physical fitness tests. There were achieved 20% increase in knowledge in the scope of nutrition and 5% increase in physical activity. There have been changes in the frequency in the consumption of the first breakfast before going to school (by 25% among the younger ones and by 17% among the older ones), an increase in the consumption of bottled water by 49% and reduction of sweet drinks by 19%. The percentage of the pupils/students consuming the recommended 5 meals increased by 33%. Physical fitness indicators were achieved over assumed 5% increase in the individual exercise tests. The Certificate was obtained after meeting the criteria and documenting the durability of the changes by 65% of 1600 educational units included in the Programme. A decrease in the frequency of overweight and obesity occurrence in the whole intervention sample by 1% was obtained; it was greater (but statistically insignificant) among younger students by 3.3% in comparison to the older ones where there was an increase of 1%. Conclusions. Summing up all achieved results the educational programme “Keep Balance” implemented on the population level aimed at children and adolescents has turned out to be effective and deserves to be continued after minor adjustments. Many positive changes have been identified as well as those that ought to be improved. Comprehensively included education and sometimes small changes in much of nutritional and physical behaviour have influenced the reduction of the percentage of pupils/students with excessive body weight, despite the fact that the average BMI has basically remained on the same level.

Opis:
The Cao Bang Basin is the northernmost of the basins related to the Cao Bang-Tien Yen Fault Zone in northern Vietnam. The basin is filled with a thick series of continental deposits. However, the exact age of the sedimentary basin infill has been under discussion for a long time. Because of new published data, the authors have decided to revisit this basin. Palynological data has allowed us to assign the Cao Bang Basin infill to the Lower Oligocene PC1 complex of the Shangcun Fm. (southern China). Among the saccate grains of gymnosperms, the domination of Cathaya and Pinus was observed, whereas angiosperms are represented by Carya, Celtis, Hammamelidaceae, Ulmus and also Pterocarya, Quercus, the Castanea–Castanopsis–Lithocarpus group, and the Loranthaceae. Among pteridophytes occur Laevigatosporites, Osmundaceae, and Pteris. The sedimentological features of the Cao Bang Basin are distinct from those of other basins from the Cao Bang-Tien Yen Fault Zone. The basin is filled with a wide variety of clastic deposits, from some of coarse-grained, alluvial-fan origin, through sandy beds of fluvial origin up to fine, organic-rich lacustrine deposits. The coarse-grained lithofacies are built of clasts derived mainly from local sources. The sandstones from the basin equally are submature or immature. They contain a lot of lithoclasts, the composition of which depends on the sample location within the basin. The potential source area is composed of older sedimentary units and of granitic rocks. The geochemical samples studied reflect the geochemical composition of silicic source rocks with only a minor contribution of basic components. The succession that fills the basin is interpreted as a typical fill for relatively long-lasting evolving half-graben or strike-slip basins. Moreover, the basin is partly occupied by a subsequent present-day sedimentary basin of Quaternary age.
