Evaluating Safety Systems for Machine Tools with Computer Numerical Control using Analytic Hierarchy Process
2019
Computer numerical control (CNC) machine tools are complex production systems with fully automatic machine parts. Nowadays, high feed rates and machining speeds are used during the machining process. Human operators are still needed to set-up the machine, load/unload workpieces and parts, load the machining code, and supervise the machining process. The operators work in an environment where automated high-speed motions occur, and consequently, CNC machine tools have to be equipped with safety systems. The approach presented in this paper was to evaluate the main safety systems of CNC machine tools based upon the analytic hierarchy process (AHP). The analyzed systems were divided into six m…
Monitoring the quality of the hospital pharmacoterapeutic process by sentinel patient program
2018
To analyze the results of sentinel patient program to monitoring the quality pharmacoterapeutic process in the hospitalized patient through medication errors.Design: Observational, prospective and transversal study. Ambit: General hospital of 1,000 beds.From May 2011 to June 2016. Sample: Patients with treatment prescribe within 24 hours of being admitted with 4 or more medications.Medication error, drugs prescribed, medications and doses dispensing, drugs administered. Safety indicators were defined based on medication errors at each stage of the pharmacotherapeutic process.Of the 746 patients studied, 334 had at least 1 medication error (44.8%; IC95%: 41.7-47.8). In the 746 treatm…
Distribution and depletion of sulfadiazine after a multiple per os dosing in gilthead sea bream (Sparus aurata) fed two different diets
2013
The distribution and depletion profile of sulfadiazine (SDZ) were investigated in gilthead sea bream (Sparus aurata) fed on fish oil (FO) or plant oil-based (PO) diets. Fish averaging 230 g were given medicated feed containing 25 mg SDZ kg-1 fish for 5 days at 24-26°C. Blood and muscle plus skin were sampled on days 1, 3, 5, 6, 8 and 9. Differences in plasma and fillet SDZ levels between the two groups were statistically insignificant. The maximum drug concentrations in plasma were 3.2 ± 1.9 μg mL-1 and 2.9 ± 1.2 μg mL-1 in the PO and FO groups, respectively. In post-medicated samples depletion rapidly reached concentrations close to the level of quantification at 72 h post medication. With…
RISK ANALISYS REGARDING HEALTH AND SAFETY AT WORK
2018
The work was created according to the provisions of the work safety legislation in force, regarding the obligation of the management of the economic agents to correctly determine the risk factors in order to ensure the measures for prevention of accidents and professional illnesses. The analysis presents the main aspects of the frequent mistakes that may arise in the risk assessment. So, it has been concluded that risks are inevitable in business, and that each activity is unique, as well as the risks from one activity to another or from one group of activities to another. Under these circumstances, it has been established that the success of an enterprise depends on how the risks were mana…
Characterisation of the microflora contaminating the wooden vats used for traditional Sicilian cheese production
2015
Traditional Sicilian cheese productions are carried out employing traditional wooden vats, called <em>tina.</em> Many studies have highlighted the beneficial role of wooden dairy equipment by contributing to enriching the milk microflora and improving the acidification processes. The present work was undertaken to evaluate the safety of the wooden vats used to coagulate milk. To this purpose, the different microbial populations hosted onto the internal surfaces of the vats used to produce two different stretched cheeses, namely <em>Caciocavallo Palermitano</em> and <em>Vastedda della valle del Belìce DOP</em>, were investigated for the presence of spoilag…
Improving quality and safety in nursing homes and home care: the study protocol of a mixed-methods research design to implement a leadership interven…
2018
IntroductionNursing homes and home care face challenges across different countries as people are living longer, often with chronic conditions. There is a lack of knowledge regarding implementation and impact of quality and safety interventions as most research evidence so far is generated in hospitals. Additionally, there is a lack of effective leadership tools for quality and safety improvement work in this context.Methods and analysisThe aim of the ‘Improving Quality and Safety in Primary Care—Implementing a Leadership Intervention in Nursing Homes and Homecare’ (SAFE-LEAD) study is to develop and evaluate a research-based leadership guide for managers to increase quality and safety compe…
Antecedents of daily team job crafting
2017
This study investigated potential antecedents of team job crafting defined as the extent to which team members engage together in increasing (social and structural) job resources and challenges, and decreasing hindering job demands. Mindful of the teamwork literature, we hypothesized that individual employee factors (self-efficacy for teamwork, daily affect), team features (team cohesion, climate) and the organizational context of teams (engaging leadership and organizational resources for teamwork) relate positively to daily team job crafting behaviour. Data were collected among 46 multi-professional rehabilitation teams whose members completed two daily surveys after their weekly meetings…
Surgical learning and guidance on operative risks and potential errors
2017
Purpose Within the framework of learning from errors, this study focused on how operative risks and potential errors are addressed in guidance to surgical residents during authentic surgical operations. The purpose of this paper is to improve patient safety and to diminish medical complications resulting from possible operating errors. Further in the process of the optimal contexts for instruction aimed at preventing risks and errors in the practical hospital environment was evaluated. Design/methodology/approach The five authentic surgical operations were analyzed, all of which were organized as training sessions for surgical residents. The data (collected via video-recoding) were analyze…
Lipodepsipeptides from Pseudomonas syringae are partially proteolyzed and are not absorbed by humans: An in vitro study
2008
There are some concerns about the use of Pseudomonas-based products as biocontrol agents because of the hemolytic activity shown by their metabolites. The effects of Pseudomonas lipodepsipeptides (LDPs) on mammals via ingestion and the LDP degradation during the digestion and intestinal permeability have not been evaluated. In this research, the susceptibility of different LDPs to degradation was assayed with enzymatic gastrointestinal digestion, and intestinal permeability to LDPs was investigated in an in vitro system based on an intestinal cell layer system. Results demonstrated that trypsin and chymotrypsin hydrolyze up to 50% of the various LDPs, and that proteolysis was further increa…
Molecular dynamics simulations of heavy ion induced defects in SiC Schottky diodes
2018
Heavy ion irradiation increases the leakage current in reverse-biased SiC Schottky diodes. This letter demonstrates, via molecular dynamics simulations, that a combination of bias and ion-deposited energy is required to produce the degradation. Peer reviewed
