Aim: To propose a new method to determine in vitro potentially bioavailable fluoride (F) in diet and toothpaste after ingestion. Methods: Diet samples (D) were obtained from 15 portions of a meal served to children in a day care centre. To simulate the ingestion of toothpaste during brushing after meals, a specific amount of toothpaste was added to the diet samples (D + T). F was determined in D and D + T after incubation in a solution that simulated “gastric juice” (0.01 M hydrochloric acid) at 37oC for 30, 60 and 120 min. Microdiffusion facilitated by HMDS was used to determine the total F concentrations in samples D and D + T. The analyses were performed using an ion specific electrode. Results: For D samples, incubation in “gastric juice” for 30, 60 and 120 min resulted in F concentrations (μg F/mL) of 0.75 ± 0.06c, 0.77 ± 0.07c and 0.91 ± 0.09b, corresponding to 75.3, 77.3 and 90.7% of the total F (1.02 ± 0.12a), respectively (p = 0.0001; ANOVA + Tukey). For D + T samples, these values of F concentrations (μg F/mL) were 2.55 ± 0.46b, 2.83 ± 0.44ab and 3.15 ± 0.37a, corresponding to 86.9, 94.8 and 106.7% of the total F (2.99 ± 0.34a), respectively (p = 0.0023; ANOVA + Tukey). Conclusion: Then, it can be concluded that the proposed method of “gastric juice” is a promising protocol for determining potentially bioavailable fluoride in the diet and toothpaste after ingestion. However, additional studies are desirable.

Title: Mathematical meaning making in children’s play? Verbal and non-verbal forms of expressionsAbstract: I analyze an episode from field work in a multilingual day-care centre in Oslo. I examine verbal and non-verbal expressions. The children are 5 years old, and the mathematics is about classification. The children are creating structure and are seeking meaning. This is a key part of their play. My findings indicate that mathematical order and structure become conscious experiences to the children. I argue that we cannot know about the children’s mathematical and communicative competence without knowing the physical context, the play in the sandpit, and the friendship between the boys.

Background: Frailty is a status of extreme vulnerability to endogenous and exogenous stressors exposing the individual to a higher risk of negative health-related outcomes. Exercise using interactive videos, known as exergames, is being increasingly used to increase physical activity by improving health and the physical function in elderly adults. The purpose of this study is to ascertain the reduction in the degree of frailty, the degree of independence in activities of daily living, the perception of one’s state of health, safety and cardiac healthiness by the exercise done using FRED over a 6-week period in elderly day care centre. Material and Methods: Frail volunteers >65 years of age, with a score of <10 points (SPPB), took part in the study. A study group and a control group of 20 participants respectively were obtained. Following randomisation, the study group (20) took part in 18 sessions in total over 6 months, and biofeedback was recorded in each session. Results: After 6 weeks, 100% of patients from the control group continued evidencing frailty risk, whereas only 5% of patients from the study group did so, with p < 0.001 statistical significance. In the case of the EQ-VAS, the control group worsened (−12.63 points) whereas the study group improved (12.05 points). The Barthel Index showed an improvement in the study group after 6 weeks, with statistically significant evidence and a value of p < 0.003906. Safety compliance with the physical activity exceeded 87% and even improved as the days went by. Discussion: Our results stand out from those obtained by other authors in that FRED is an ad hoc-designed exergame, significantly reduced the presence and severity of frailty in a sample of sedentary elders, thus potentially modifying their risk profile. It in turn improves the degree of independence in activities of daily living and the perception of one’s state of health, proving to be a safe and cardiac healthy exercise. Conclusions: The study undertaken confirms the fact that the FRED game proves to be a valid technological solution for reducing frailty risk. Based on the study conducted, the exergame may be considered an effective, safe and entertaining alternative.

The article examines children’s clothes in the practices of everyday life in day care. The data for the article are drawn from an ethnography of three- to seven-year-old children’s day care groups in a day care centre intended for children of shift-working parents in southern Finland. Rather than focusing on the relations between identity, representation and clothing, the article examines what clothes do in the everyday practices of day care. Clothes are seen, first, as mediating perception, and, second, as taking part in and maintaining affective everyday practices. The effects of wearing clothes are analysed using the concept of plug-ins by Latour and that of affordances proposed by Gibson. The plug-ins detect the ways in which objects transmit selfhood, while affordances describe the relation between body and environment in perception. Through the analysis of everyday practices of wearing clothing, clothes are seen as connectors. They enhance, diminish or expand possibilities for perception, action and affective practices in which children engage, thereby altering the children’s ways of being. The article proposes that the wearing of clothing plays a role in constituting selfhood outside of mere representations.
