Home-Delivered Meals: Characterization of Food Intake in Elderly Beneficiaries
2021
Objective. In this study, we focus on elderly people (≥70 years old) benefiting from a home delivery meal service as part of a social welfare program. We aimed to: (i) assess the gap between the recommended and actual nutritional intake in this population and (ii) study the relationship between the intake of nutrients and the variables characterizing the participants’ health and nutritional status. Design. A dietary survey (24-hour record) was conducted during a home interview, with 64 people receiving a home delivery meal service (75% women
A frequency compensation algorithm of four-wheel coherence random road
2013
Published version of an article in the journal: Mathematical Problems in Engineering. Also available from the publisher at: http://dx.doi.org/10.1155/2013/986584 Open access The road surface roughness is the main source of kinematic excitation of a moving vehicle, which has an important influence on vehicle performance. In recent decades, random road models have been widely studied, and a four-wheel random road time domain model is usually generated based on the correlation of the four-wheel input, in which a coherence function is used to describe the coherence of the road input between the left and right wheels usually. However, during our research, there are some conditions that show that…
Assistive robotic walker parameter identification for estimation of human thrust without force sensors
2017
In this paper we propose a parameter identification procedure for the wheel-motor dynamic of a robotic walker, i.e. a commercial trolley for elderly people endowed with cognitive, sensing and guidance capabilities. The objective of the wheel-motor dynamic model is to generate a suitable time reference to be used in an estimation algorithm. The ultimate goal of the estimation algorithm is to retrieve the thrust, i.e. torque and force, that the older adult user of the robotic walker applies to the platform. These quantities are of paramount importance in order to adopt intelligent and comfortable walker guidance algorithms. The novelty of this approach is the avoidance of additional costly se…

Home delivery meal : issue and impact of this service on the nutritional status of older people living at home
2021
Introduction. In old age, the onset of disabilities (physical, cognitive) can lead older adults to have difficulty doing certain tasks of daily life, particularly those related to alimentation (shopping, meal preparation). To alleviate these difficulties, more and more elderly people are using home delivery meal services. The objective of this thesis is to question the place and role of such services in preventing undernutrition in the elderly population. Undernutrition is common in this population and results from an imbalance between nutritional intake and needs. Materials and methods. In this thesis, several approaches were combined. A systematic literature review documented the undernut…
Indagine sperimentale per la valutazione del comfort acustico nelle carrozze ferroviarie
2005
In questo lavoro, reso possibile dall’interesse e dalla disponibilità mostrata concreta-mente dalla Divisione Trasporto Regionale di Trenitalia (Direzione Regionale Sicilia), sono stati approfonditi alcuni aspetti concernenti i fenomeni acustici all’interno dei rotabili fer-roviari, al fine di individuare eventuali legami tra le caratteristiche del sistema costituito dal binomio tracciato-rotabile e le condizioni di comfort acustico dei passeggeri. Una indagine sperimentale di rilevamento delle condizioni acustiche è stata condotta su alcune vetture di convogli operativi su una linea ferroviaria che attraversa il territorio della provincia di Palermo su tracciato misto, urbano ed extraurban…
Renewable Energy Resources for Mathematics Learning : Windmills and Water Wheels at the Math Class
2018
The Finnish National Core Curriculum has been renewed in 2014 and the National Core Curriculum of Korea has been renewed in 2015. Although, the Finnish and the Korean educational culture is radically different from each other, they are both producing top results in international educational assessments and their renewed curricula contain some very similar components. The "multidisciplinary learning module" in Finland and the "STEAM framework" in Korea are both emphasizing the complexity of phenomena, which can be understood only in context and by employing multiple perspectives based on the combination of various subjects. In this workshop, we introduce how to construct windmills and water …
