Opis:
The study aimed to assess the operation of the mechanical and biological wastewater treatment plant in Michów (Poland) in terms of the effectiveness of removing contaminants from mixed wastewater (dairy and domestic) and technological reliability. The wastewater treatment plant is owned by the Dairy Cooperative “Michowianka”. It is intended to treat mixed sewage, consisting of technological and sanitary sewage as well as part of rainwater from the plant, domestic wastewater supplied by a sewerage system from Michów, and wastewater delivered from septic tanks. In 2017 and in the first quarter of 2018, the permeate from the whey thickening process was also sent to the treatment plant. The period 2017-2021 was covered by the analysis. The analysis included the indicators from the fundamental group (TSS, BOD5, COD), biogenic indices (total phosphorus, total nitrogen, and ammonium nitrogen). The applied technology ensured the removal of total suspended solids, BOD5, and COD at the level of over 96%. Total phosphorus was removed with an average efficiency of 91%. Slightly lower effects were found in the elimination of total nitrogen – 78.5% on average, while the ammonium nitrogen removal rate was 88% on average. Due to the high efficiency of the facility, the values of the standard contamination indicators at the outflow, as a rule, met the requirements specified in the water permit. The technological reliability of the wastewater treatment plant in Michów, determined by the Weibull method, was at a high level, usually exceeding 90%. The reliability analysis shows that the facility in Michów has a high capacity to treat wastewater to the extent required for the wastewater receiver, and that the treated wastewater discharge does not cause negative changes in the environment. It indicates a high probability of obtaining the wastewater quality at the outflow from the treatment plant meeting the water permit requirements.

Background. Feeding difficulties in severely demented patients present a significant challenge for all involved in care. ecent studies have found that there are differences between nurse’s attitudes toward artificial nutrition and hydration in different countries. Objectives.the aim of the study was to offer an analysis of convictions of norwegian and Polish caring staff toward feeding problems in patients with advanced dementia and explore the w ay they cope with such situations. Material and methods.the data was collected in the “engensenteret” nursing home in Bergen (Norway) and in Medical centre nursing home in Brzeg (Poland). the study group comprised 52 participants and involved staff taking care of severely demented patients. a self-constructed questionnaire was used. Results.contrary to the norwegians, all Polish respondents favored forced feeding of severely demented patients. almost half of respondents suggested that any decisions about aggressive feeding should be made separately by physician and none would offer decision-making power to the patient’s family. Polish respondents stated significantly more often that artificial nutrition will improve quality of life in demented patients. Conclusions 1. the convictions of norwegian and Polish respondents according introduction of artificial nutrition in end-stage dementia and its efficiency in this population were significantly different. 2. the respondents of both nations would generally delegate the decision-making power separately to the physician. 3. the development of nutritional guidelines for advanced dementia and correction of common misconceptions about the effectiveness of aggressive nutritional intervention in this popu lation is recommended.
Wstęp. Trudności w odżywianiu pacjentów w zaawansowanej demencji stanowią ogromne wyzwanie dla personelu sprawującego nad nimi opiekę. Liczne badania potwierdziły, że postawy pielęgniarek wobec problemu sztucznego odżywienia i nawadniania pacjentów są różne w poszczególnych państwach. Cel pracy. Analiza przekonań norweskiego i polskiego personelu opiekuńczego, dotyczących problemów w odżywianiu występujących u pacjentów z zaawansowaną demencją i wyjaśnienie, jak respondenci sobie z nimi radzili. Materiał i metody. Badanie przeprowadzono w domu opieki “Engensenteret” w Bergen (Norwegia) oraz w Zakładzie Opiekuńczo- Leczniczym Brzeskiego Centrum Medycznego w Brzegu (Polska). Grupa badana składała się z 52 członków personelu opiekuńczego. Jako narzędzia badawczego użyto kwestionariusza własnej konstrukcji. Wyniki. Wszyscy polscy respondenci, w przeciwieństwie do grupy norweskiej, opowiadali się za przymusowym karmieniem pacjentów z zaawansowaną demencją. Prawie połowa respondentów twierdziła, iż każdą decyzję dotyczącą sztucznego odżywiania i nawadniania powinien podjąć lekarz, nikt z badanych nie oddałby prawa decyzji w tej sprawie rodzinie chorego. Polscy respondenci twierdzili istotnie częściej, że sztuczne odżywianie poprawia ogólną jakość życia chorego na demencję. Wnioski. 1. Przekonania norweskich i polskich respondentów dotyczące podejmowania sztucznego odżywiania w zaawansowanej demencji oraz jego efektywności dla tej populacji chorych były znacząco różne. 2. Według większości respondentów prawo do podejmowania każdej decyzji dotyczącej rozpoczęcia sztucznego odżywiania ma jedynie lekarz. 3. Należy opracować ogólne wytyczne i standardy polityki żywieniowej w stosunku do chorych z zaawansowaną demencją, a także wyjaśnić częste nieporozumienia związane z domniemaną efektywnością sztucznego odżywiania w tej populacji pacjentów.

Opis:
Preschool period is a stage of intensive development of the food preferences and the pro-health attitudes associated with normal eating behaviors and consequently eating habits in adulthood. The aim of the study was to assess eating behaviors of children attending kindergartens in relation to selected socio-economic factors in their families.The study was conducted in a group of 325 children, whose average age was 5.23 ±1.30 years, attending nine kindergartens in Krakow. The questionnaire was filled in by 51.4% (N = 167) of parents of boys and 48.6% (N = 158) of girls. To conduct qualitative assessment of nutrition habits the Food Frequency Questionnaire (FFQ) was used with addition of questions regarding the socio-economic situation of the surveyed families. Differences in selected dietary behaviors of children were evaluated by gender, family income and parents’ educational level. The study indicates the existence of the relationship between food-related behaviour of preschool children and parents’ education level and family income.The resulting image of dietary behaviours of children in the study group has identified numerous anomalies that require an active and ongoing nutrition education for children and their parents.

Opis:
The goal of this study is to evaluate the relationship between the time spent in front of a computer or TV and eating habits in kindergarten children. The study was conducted in May and September 2012 in two kindergartens in Krakow (n=61) and in a kindergarten in Podłęże, a village near Krakow (n=34). The average age of the studied children was 5.02±1.17. 40 parents of boys and 55 parents of girls took part in the study. The differences in responses related to gender and place of living were checked. The analyses of correlations among particular factors, including BMI, were conducted by means of the Spearman rank. Most of the kindergarten children (60%) spent an hour or less in front of TV. No relation between the time spent in front of TV or computer and gender or place of living or BMI interpretation was noticed. The time devoted to watching TV was connected with the frequency of snacks and fast-food consumption. The higher the education of mothers the less frequently children eat in front of TV. The frequency of sweetened beverages was also linked with the time spent in front of a computer. The relation between time spent in front of TV or computer and frequency of high energy food consumption among children was confirmed in the study. An effort should be made to educate parents about probable increased risk of children’s obesity connected with watching media

Opis:
Eating habits and risk of malnutrition among students of the University of the Third Age from Krakow and the poviat of Wieliczka The problem of malnutrition prevalence is rarely evaluated among older people living in the home environment. The aim of the study is to assess eating habits and prevalence of malnutrition in a group of students of Universities of the Third Age (UTA) from Krakow and the poviat of Wieliczka. The study conducted in 2013 consisted of 77 people, whose average age was 67.16 ± 5.44 years, including 67 women and 10 men. The study involved 28 people from UTA in Krakow, and 49 of the selected UTA in the poviat of Wieliczka.The risk assessment used a standardized mini nutritional assessment (MNA) scale, while the assessment of eating behaviour used a Food Frequency Questionnaire (FFQ). According to the MNA no one was diagnosed with malnutrition, while 10 respondents were at risk of malnutrition. These individuals had lower self-esteem of nutritional status and health, and, compared with the recommendations, consumed small amount of liquids during the day, which was associated with occurrence of mental stress or illness over the past three months.According to the FFQ assessment, the majority of respondents implement proper eating habits. However, mistakes are made in respect of the low frequency of consumption of fish and milk and their products.

Opis:
Lifestyle determines human diet. Such factors as school environment, aggressive advertising or nutrition fashion affect the diet during adolescence. The aim of this study was to assess selected eating habits in relation to the assessment of the nutritional status of adolescents in upper secondary school age. Studies on students, mainly from rural areas, were carried out in the school year 2010. The study included 114 students aged 16-18 years, from upper secondary school with diversified educational profiles in Lesko. To assess the diet a qualitative method, that is, an anonymous food frequency questionnaire (FFQ) of consumption of selected products and beverages, was used. Assessment of nutritional status was based on the interpretation of BMI and WHtR (Waist to Height Ratio) obtained from the students’ anthropometric measurements results. The statistical significance in the interpretation of BMI in gender groups (p=0.0075) and groups with various educational profiles (p=0.0013) has been observed. On the basis of the interpretation of WHtR the abdominal obesity was more common among girls (18.42%) and students of the secondary technical school of catering (24.24%). Gender was a significant factor differentiating the number of meals (p=0.0221). Eating irregular meals was proven in the study and the intervals between meals in distinguished groups were up to 4 hours (45.85% of the total). Adolescents from the region of Podkarpacie declared lower frequency of consumption of “fast-food” products. Occurring abnormal eating habits were characteristic for the examined age group. Occurring dietary mistakes did not significantly affect the assessment of body mass.

Purpose: According to the available international recommendations, at least one independent verifi cation of the calculations of number of monitor unit (MU) is required for every patient treated by teleradiotherapy. The aim of this study was to estimate the differences of dose distributions calculated with two treatment planning systems: Eclipse (Varian) and Oncentra MasterPlan (Elekta). Materials and methods: The analysis was performed for 280 three-dimensional conformal radiotherapy treatment (3D-CRT) plans with photon beams from Varian accelerators: CL 600C/D X6 MV (109 plans), CL 2300C/D X6 MV (43 plans), and CL 2300C/D X15 MV (128 plans). The mean doses in the planning target volume (PTV) and doses at the isocenter point obtained with Eclipse and Oncentra MasterPlan (OMP) were compared with Wilcoxon matched-pairs signed rank test. Additionally, the treatment planning system (TPS) calculations were compared with dosimetric measurements performed in the inhomogeneous phantom. Results: Data were analysed for 6 MV plans and for 15 MV plans separately, independently of the treatment machine. The dose values calculated in Eclipse were significantly (p <0.001) higher compared to calculations of OMP system. The average difference of the mean dose to PTV was (1.4 ± 1.0)% for X6 MV and (2.5 ± 0.6)% for X15 MV. Average dose disparities at the isocenter point were (1.3 ± 1.9)% and (2.1 ± 1.0)% for X6 MV and X15 MV beams, respectively. The largest differences were observed in lungs, air cavities, and bone structures. Moreover the variation in dosimetric measurements was less as compared to Eclipse calculations. Conclusions: OMP calculations were introduced as the independent MU verification tool with the first action level range equal to 3.5%.

Introduction: The results of national and international studies demonstrate the relationship of consumption of cola-type beverages by adolescents with increased dependence on other psychoactive substances, such as alcohol or tobacco. Aim: To assess the relationship between consumption of cola and functional drinks (energy and isotonic drinks) and other stimulants including coffee, tea, alcohol and cigarettes in a group of high school students. Material & methods: 120 students (16–17 years) attending upper secondary school in Lesko participated in the survey. The anonymous questionnaire collected data on frequency of consumption of selected products and beverages (FFQ), including functional beverages. To assess the differences between groups the Mann-Whitney U-test was appplied, while the relationship between variables was analyzed using the Spearman correlation coefficient (rs) at statistical significance level α=0.05. Results: The results showed that sugar beverages such as cola (soft drink), were consumed most frequently by young people (2.50±0.92). Of functional beverages, respondents choose energy drinks more often (2.07±0.87) than isotonic beverages (1.66±0.76). Among female respondents, a positive correlation between the consumption of energy drinks and cola drinks was found (rs=0.34, p=0.0001). Girls who smoke cigarettes reported consuming energy drinks significantly more often (p=0.0212) than non-smokers. The frequency of consumption of caffeinated beverages (cola and energizing drinks) in the surveyed group had no correlation with consumption of alcoholic beverages and tea. Conclusion: Excessive intake of caffeine by young people may lead to increased use of other stimulants. This indicates a need for quantitative data on consumption of caffeinated beverages by adolescents.
