The objective of this work was to evaluate the reuse of sucrose syrup in pineapple ( Ananas comosus ) osmotic dehydration and the application of the spent solution in fruit dragee formulation. Osmotic dehydration trials were performed in five cycles (65° Brix/45°C/3 hours), directly reusing the osmotic solution, with only one intermediate reconditioning step. Variations in osmotic solution properties and in dehydration parameters were observed, as well as a low microbial load in the system. The spent solution was rich in vitamin C (30 mg 100 g -1 ). Pineapple dragee covered with red fruits and acai powders were obtained with the reconditioned spent solution used as an adhesion solution. The dragee presented high levels of vitamin C (176 mg 100 g -1 ), polyphenols (154 mg GAE 100 -1 g), carotenoids (220 µg 100 g -1 ), and potassium (330 mg 100 g -1 ). The product showed good sensory acceptance and purchase intention. Reusing sucrose syrup is technically feasible during pineapple osmotic dehydration, as is the application of the spent solution as an ingredient in fruit dragee production.

Background: Underweight, overweight, and obesity in childhood and adolescence are associated with adverse health consequences throughout the life-course. Our aim was to estimate worldwide trends in mean body-mass index (BMI) and a comprehensive set of BMI categories that cover underweight to obesity in children and adolescents, and to compare trends with those of adults. Methods: We pooled 2416 population-based studies with measurements of height and weight on 128·9 million participants aged 5 years and older, including 31·5 million aged 5–19 years. We used a Bayesian hierarchical model toestimate trends from 1975 to 2016 in 200 countries for mean BMI and for prevalence of BMI in the following categories for children and adolescents aged 5–19 years: more than 2 SD below the median of the WHO growth reference for children and adolescents (referred to as moderate and severe underweight hereafter), 2 SD to more than 1 SD below the median (mild underweight), 1 SD below the median to 1 SD above the median (healthy weight), more than 1 SD to 2 SD above the median (overweight but not obese), and more than 2 SD above the median (obesity). Findings: Regional change in age-standardised mean BMI in girls from 1975 to 2016 ranged from virtually no change (–0·01 kg/m² per decade; 95% credible interval –0·42 to 0·39, posterior probability [PP] of the observed decrease being a true decrease=0·5098) in eastern Europe to an increase of 1·00 kg/m² per decade (0·69–1·35, PP>0·9999) in central Latin America and an increase of 0·95 kg/m² per decade (0·64–1·25, PP>0·9999) in Polynesia and Micronesia. The range for boys was from a non-significant increase of 0·09 kg/m² per decade (–0·33 to 0·49, PP=0·6926) in eastern Europe to an increase of 0·77 kg/m² per decade (0·50–1·06, PP>0·9999) in Polynesia and Micronesia. Trends in mean BMI have recently flattened in northwestern Europe and the high-income English-speaking and Asia-Pacific regions for both sexes, southwestern Europe for boys, and central and Andean Latin America for girls. By contrast, the rise in BMI has accelerated in east and south Asia for both sexes, and southeast Asia for boys. Global age-standardised prevalence of obesity increased from 0·7% (0·4–1·2) in 1975 to 5·6% (4·8–6·5) in 2016 in girls, and from 0·9% (0·5–1·3) in 1975 to 7·8% (6·7–9·1) in 2016 in boys; the prevalence of moderate and severe underweight decreased from 9·2% (6·0–12·9) in 1975 to 8·4% (6·8–10·1) in 2016 in girls and from 14·8% (10·4–19·5) in 1975 to 12·4% (10·3–14·5) in 2016 in boys. Prevalence of moderate and severe underweight was highest in India, at 22·7% (16·7–29·6) among girls and 30·7% (23·5–38·0) among boys. Prevalence of obesity was more than 30% in girls in Nauru, the Cook Islands, and Palau; and boys in the Cook Islands, Nauru, Palau, Niue, and American Samoa in 2016. Prevalence of obesity was about 20% or more in several countries in Polynesia and Micronesia, the Middle East and north Africa, the Caribbean, and the USA. In 2016, 75 (44–117) million girls and 117 (70–178) million boys worldwide were moderately or severely underweight. In the same year, 50 (24–89) million girls and 74 (39–125) million boys worldwide were obese. Interpretation: The rising trends in children’s and adolescents’ BMI have plateaued in many high-income countries, albeit at high levels, but have accelerated in parts of Asia, with trends no longer correlated with those of adults.

Bosnia and Herzegovina is a country with complex and asymmetrical structure (two entities, District Brčko, and cantons with own government and ministries), The number of ministries in the BiH is enormous. Coordination between so many governments and ministries is demanding while most of the citizens are completely lost in that institutional labyrinth. One of the possible ways how governments and their institutions could help citizens, ensure direct communication with them and improve mutual coordination is more intensive use of social networks (Facebook, Twitter). Social networks have potential to increase visibility and transparency of the work of governments and their institutions. Also, they could make policy processes more inclusive and increase confidence between governments and citizens. The main goal of the paper is to explore presence and activity on social networks in BiH government institutions, to discuss major challenges and to propose potential options for better implementation of social networks in these institutions.

In this study, authors analyze the practices and effectiveness of educational management and leadership, according to the selected psychological and sociological characteristics of school principals in Croatia and Bosnia & Herzegovina. The selected psychological traits have been already analyzed in the case of entrepreneurial orientation and proved to be relevant for differentiation of schools and principals, according to their inclination to entrepreneurship. In this paper, more comprehensive, analytic criteria are used to explore the effectiveness of educational management and leadership practices in the sample of Croatian and B&H principals. The objective of the study is to determine the significance of the psychological and sociological variables for the practice of school management and leadership, as well as to suggest potential implications for school leaders’ professional orientation and development.
