Description: IJERPH, Vol. 15, Pages 1489: The State of Knowledge about Nutrition Sources of Vitamin D, Its Role in the Human Body, and Necessity of Supplementation among Parents in Central Poland International Journal of Environmental Research and Public Health doi: 10.3390/ijerph15071489 Authors: Katarzyna Zadka Ewelina Pałkowska-Goździk Danuta Rosołowska-Huszcz The percentage of children with vitamin D deficiency in Poland is alarming. The aim of the study was to assess the knowledge about sources of food and the function of vitamin D, as well as the frequency of its supplementation. A survey was conducted among the parents of children from Central Poland attending primary schools, and a questionnaire containing mainly open-ended questions was used to collect the data. Most mothers knew at least one of the functions of vitamin D in the body but had a low level of knowledge about its dietary sources. Only a small group of respondents supplemented themselves and their children with vitamin D. Statistically significant influences on the level of knowledge about the functions and sources of vitamin D were place of residence (i.e., better knowledge in the countryside) and mothers’ level of education (i.e., the better educated, the greater knowledge). In the case of monthly income level, such impact was observed only in relation to the knowledge of vitamin D functions. Concerning the frequency of supplementation, only maternal level of education had a statistically significant effect (i.e., the higher the education level, the higher the frequency of supplementation). In addition, mothers who were aware of functions of vitamin D and nutritional sources, significantly more frequently supplemented vitamin D.

Description: IJERPH, Vol. 15, Pages 1490: Quantitative Microbial Risk Assessment for Workers Exposed to Bioaerosol in Wastewater Treatment Plants Aimed at the Choice and Setup of Safety Measures International Journal of Environmental Research and Public Health doi: 10.3390/ijerph15071490 Authors: Annalaura Carducci Gabriele Donzelli Lorenzo Cioni Ileana Federigi Roberto Lombardi Marco Verani Biological risk assessment in occupational settings currently is based on either qualitative or semiquantitative analysis. In this study, a quantitative microbial risk assessment (QMRA) has been applied to estimate the human adenovirus (HAdV) health risk due to bioaerosol exposure in a wastewater treatment plant (WWTP). A stochastic QMRA model was developed considering HAdV as the index pathogen, using its concentrations in different areas and published dose–response relationship for inhalation. A sensitivity analysis was employed to examine the impact of input parameters on health risk. The QMRA estimated a higher average risk in sewage influent and biological oxidation tanks (15.64% and 12.73% for an exposure of 3 min). Sensitivity analysis indicated HAdV concentration as a predominant factor in the estimated risk. QMRA results were used to calculate the exposure limits considering four different risk levels (one illness case per 100, 1.000, 10.000, and 100.000 workers): for 3 min exposures, we obtained 565, 170, 54, and 6 GC/m3 of HAdV. We also calculated the maximum time of exposure for each level for different areas. Our findings can be useful to better define the effectiveness of control measures, which would thus reduce the virus concentration or the exposure time.

Description: Algorithms, Vol. 11, Pages 106: Fractional-Order Closed-Loop Model Reference Adaptive Control for Anesthesia Algorithms doi: 10.3390/a11070106 Authors: Gerardo Navarro-Guerrero Yu Tang The design of a fractional-order closed-loop model reference adaptive control (FOCMRAC) for anesthesia based on a fractional-order model (FOM) is proposed in the paper. This proposed model gets around many difficulties, namely, unknown parameters, lack of state measurement, inter and intra-patient variability, and variable time-delay, encountered in controller designs based on the PK/PD model commonly used for control of anesthesia, and allows to design a simple adaptive controller based on the Lyapunov analysis. Simulations illustrate the effectiveness and robustness of the proposed control.

Description: Entropy, Vol. 20, Pages 529: Curvature Invariants of Statistical Submanifolds in Kenmotsu Statistical Manifolds of Constant ϕ-Sectional Curvature Entropy doi: 10.3390/e20070529 Authors: Simona Decu Stefan Haesen Leopold Verstraelen Gabriel-Eduard Vîlcu In this article, we consider statistical submanifolds of Kenmotsu statistical manifolds of constant ϕ-sectional curvature. For such submanifold, we investigate curvature properties. We establish some inequalities involving the normalized δ-Casorati curvatures (extrinsic invariants) and the scalar curvature (intrinsic invariant). Moreover, we prove that the equality cases of the inequalities hold if and only if the imbedding curvature tensors h and h∗ of the submanifold (associated with the dual connections) satisfy h=−h∗, i.e., the submanifold is totally geodesic with respect to the Levi–Civita connection.

Description: IJERPH, Vol. 15, Pages 1491: Accounting for Fairness in a Two-Stage Stochastic Programming Model for Kidney Exchange Programs International Journal of Environmental Research and Public Health doi: 10.3390/ijerph15071491 Authors: Hyunwoo Lee Seokhyun Chung Taesu Cheong Sang Hwa Song Kidney exchange programs, which allow a potential living donor whose kidney is incompatible with his or her intended recipient to donate a kidney to another patient in return for a kidney that is compatible for their intended recipient, usually aims to maximize the number of possible kidney exchanges or the total utility of the program. However, the fairness of these exchanges is an issue that has often been ignored. In this paper, as a way to overcome the problems arising in previous studies, we take fairness to be the degree to which individual patient-donor pairs feel satisfied, rather than the extent to which the exchange increases social benefits. A kidney exchange has to occur on the basis of the value of the kidneys themselves because the process is similar to bartering. If the matched kidneys are not of the level expected by the patient-donor pairs involved, the match may break and the kidney exchange transplantation may fail. This study attempts to classify possible scenarios for such failures and incorporate these into a stochastic programming framework. We apply a two-stage stochastic programming method using total utility in the first stage and the sum of the penalties for failure in the second stage when an exceptional event occurs. Computational results are provided to demonstrate the improvement of the proposed model compared to that of previous deterministic models.

Description: Entropy, Vol. 20, Pages 527: Category Structure and Categorical Perception Jointly Explained by Similarity-Based Information Theory Entropy doi: 10.3390/e20070527 Authors: Romain Brasselet Angelo Arleo Categorization is a fundamental information processing phenomenon in the brain. It is critical for animals to compress an abundance of stimulations into groups to react quickly and efficiently. In addition to labels, categories possess an internal structure: the goodness measures how well any element belongs to a category. Interestingly, this categorization leads to an altered perception referred to as categorical perception: for a given physical distance, items within a category are perceived closer than items in two different categories. A subtler effect is the perceptual magnet: discriminability is reduced close to the prototypes of a category and increased near its boundaries. Here, starting from predefined abstract categories, we naturally derive the internal structure of categories and the phenomenon of categorical perception, using an information theoretical framework that involves both probabilities and pairwise similarities between items. Essentially, we suggest that pairwise similarities between items are to be tuned to render some predefined categories as well as possible. However, constraints on these pairwise similarities only produce an approximate matching, which explains concurrently the notion of goodness and the warping of perception. Overall, we demonstrate that similarity-based information theory may offer a global and unified principled understanding of categorization and categorical perception simultaneously.

Description: IJERPH, Vol. 15, Pages 1492: Indigenous Australians Perceptions’ of Physical Activity: A Qualitative Systematic Review International Journal of Environmental Research and Public Health doi: 10.3390/ijerph15071492 Authors: Emma E. Dahlberg Sandra J. Hamilton Fatuma Hamid Sandra C. Thompson Given poorer health and higher rates of chronic disease seen in Indigenous populations around the world and the evidence linking exercise with health and wellbeing, recommendations for encouraging and increasing Indigenous people’s participation in physical activity are needed. This paper systematically reviews published qualitative research papers exploring issues related to the perspectives of Indigenous Australians around physical activity. Key terms relevant to attitudes, beliefs, and perceptions of Indigenous Australians on physical activity and sport were explored in 11 electronic bibliographic databases including EMBASE, Medline and Web of Science. Of the 783 studies screened, eight qualitative studies met the selection criteria; only one was exclusively undertaken in a rural setting. Four major themes emerged: family and community, culture and environment, sport, and gender differences. Men highlighted sport and going on walkabout as preferred types of physical activity while women preferred family-focused activities and activities and support for women's sport. Several studies found exercise was supported when in the context of family and community but was considered shameful when done only for oneself. Sport was regarded as playing an influential role in bringing communities together. Group, community, or family activities were desired forms of physical activity with the environment they are conducted in of high importance. These findings should inform future research and intervention programs aimed at addressing the physical activity levels of Indigenous Australians and may be relevant to other Indigenous populations.
