La percezione degli insegnanti degli aspetti funzionali e problematici della scuola domiciliare per alunni malati

Many students with medical needs are benefitting from the home-schooling service. However, such service has seldom been investigated. The present qualitative study investigated the characteristics of home-schooling service in a sample of 43 teachers who provided such service during the 2018/2019 school year. The most salient problematic aspects refer to the relationship with illness, the complexity of several organizational and logistical tasks and work dispersion. Information and communication technologies are mentioned in an ambivalent way; a good relationship with the class of belonging of the child and the teacher’s capability to fully take care of all the educational and developmental needs of the student are mentioned as an effective way to proper home-teaching practice. Home-schooling for students with health care needs requires a particular organization and specific teacher training and in-service supervision. Some of these solutions are also discussed in relation to the international literature in the field.Molti studenti malati usufruiscono della scuola domiciliare, ma questo servizio è stato finora scarsamente indagato. Il presente studio qualitativo ha indagato le caratteristiche della scuola domiciliare in un campione di 43 docenti in servizio nell’anno 2018/2019. Gli elementi problematici indicati più spesso riguardano il rapporto con la malattia, la complessità e la dispersione del lavoro. Le tecnologie didattiche vengono indicate in modo ambivalente; I contatti con la classe di appartenenza e la capacità del docente domiciliare di farsi carico pienamente della situazione sono stati indicati come aspetti funzionali ad un insegnamento efficace. La scuola domiciliare richiede una gestione e una formazione e supervisione specifica, che viene discussa in alcuni suoi aspetti salienti anche in relazione a soluzioni presentate nel panorama internazionale

Development perspectives for biogas production from agricultural waste in Friuli Venezia Giulia (Nord-East of Italy)

The latest directives of the Energy and Environment Policy of the European Union (EU) established a new framework for renewable sources (Directive EC 28/2009; European Commission, 2009). The Italian Energy Action Plan of 2010 set a target of at least 17% of total energy generated from renewable sources by 2020. In this context biogas from waste and biomass is a potential energy source that can be used for the production of heat, electricity and fuel. The objective of this work was to determine the potential energy production from anaerobic digestion of animal wastes and agricultural residues in Friuli Venezia Giulia (Nord-East Italy). For an assessment of biogas as an energy source, based on direct conversion by agricultural farms, it is important to establish the amount of the waste. In this study, biogas amount which can be obtained was calculated for all municipalities in the Friuli Venezia Giulia Region (North-East of Italy) by using the number of livestock animals, the cereal area for agricultural residues and also considering various criteria such as the rate of dry matter and availability. The calculated regional biogas potential is about 187 (N)Gm3 when using animal waste, straw and corn stalk. The potential of biogas energy equivalent of Friuli Venezia Giulia is about 3 600 TJ (LHV) may be able to replace 2.6% of final energy consumption in Friuli Venezia Giulia (3 339 ktoe) and about 10% of the final electricity consumption (864 ktoe) considering an electrical efficiency of 30% with the biogas engine

Accident investigation related to the use of chainsaw

Operating in woods might be highly dangerous as it takes place in hard environments because of slopes, uneven ground and the presence of the underwood that may prevent machines and operators from moving. The chainsaw is a widely-used tool in agriculture, in forestry as well as for professional and hobby-related purposes. This article has the aim to highlight the state of injuries both for professional and domestic uses. The research focused on web-based report of news published between 2007 and 2012 about mortal and non-mortal accidents occurred in Italy and involving people who were using a chainsaw. On the whole, 336 cases were collected over a 5-year period. The results of the work are represented by a series of thematic maps related to the causative agent, the age of the injured and the seat of the injury. Furthermore, it is confirmed that the operator’s head is the most exposed area of the body and is often correlated with the death of the operator (death is often due to collision against the chainsaw blade, facial traumas as well sudden contact with parts of the plant). The study shows the dangers of chainsaw. Even workers experts are involved in serious injury and death. The study highlights the needing of looking for technical solutions and specific procedures for training unskilled worker

Characterization of Human Subcutaneous Adipose Tissue and Validation of the Banking Procedure for Autologous Transplantation

Adipose tissue (AT) is composed of a heterogeneous population which comprises both progenitor and differentiated cells. This heterogeneity allows a variety of roles for the AT, including regenerative functions. In fact, autologous AT is commonly used to repair soft tissue defects, and its cryopreservation could be a useful strategy to reduce the patient discomfort caused by multiple harvesting procedures. Our work aimed to characterize the cryopreserved AT and to validate its storage for up to three years for clinical applications. AT components (stromal vascular fraction-SVF and mature adipocytes) were isolated in fresh and cryopreserved samples using enzymatic digestion, and cell viability was assessed by immunofluorescence (IF) staining. Live, apoptotic and necrotic cells were quantified using cytometry by evaluating phosphatidylserine binding to fluorescent-labeled Annexin V. A multiparametric cytometry was also used to measure adipogenic (CD34+CD90+CD31−CD45−) and endothelial (CD34+CD31+CD45−) precursors and endothelial mature cells (CD34−CD31+CD45−). The maintenance of adipogenic abilities was evaluated using in vitro differentiation of SVF cultures and fluorescent lipid staining. We demonstrated that AT that is cryopreserved for up to three years maintains its differentiation potential and cellular composition. Given our results, a clinical study was started, and two patients had successful transplants without any complications using autologous cryopreserved AT
