Time-Dependent Multiple Depot Vehicle Routing Problem on Megapolis Network under Wardrop's Traffic Flow Assignment
2018
In this work multiple depot vehicle routing problem is considered in case of variable travel times between nodes on a metropolis network. This variant of the classic multiple depot vehicle routing problem is motivated by the fact that in urban contexts variable traffic conditions play an essential role and can not be ignored in order to perform a realistic optimization. Time-travel matrices corresponding to each period of planning horizon were formed by solving the traffic assignment problem in conjunction with shortest path problem. Routing problem instances include from 20 to 100 customers randomly chosen from a road network of Saint-Petersburg. The results demonstrate that taking into ac…
Advantages of fitting contrast curves using logistic function: a technical note.
2013
Objective The aim of this article is to demonstrate how the contrast properties of an imaging system can be ideally fitted with the use of stripe patterns and the logistic function. Study Design Stripe patterns with defined amounts of line pairs (lp/mm) per mm (10-20 lp/mm) were recorded with the use of digital photostimulable storage phosphor. Scan data and normalized image data were analyzed with the use of ImageJ and MatLab to calculate different contrast curves. Results For original scan data, the goodness of fit was 0.0000019 (sum of squared error [SSE]). The R-square was 0.9998. For normalized data the goodness of fit was 0.0007 (SSE) and the R-square 0.998. An amount of 50% contrast …
Perceived major experiences of discrimination, ethnic group, and risk of psychosis in a six-country case-control study
2021
AbstractBackgroundPerceived discrimination is associated with worse mental health. Few studies have assessed whether perceived discrimination (i) is associated with the risk of psychotic disorders and (ii) contributes to an increased risk among minority ethnic groups relative to the ethnic majority.MethodsWe used data from the European Network of National Schizophrenia Networks Studying Gene-Environment Interactions Work Package 2, a population-based case−control study of incident psychotic disorders in 17 catchment sites across six countries. We calculated odds ratios (OR) and 95% confidence intervals (95% CI) for the associations between perceived discrimination and psychosis using mixed-…
A Patient Registry to Improve Patient Safety: Recording General Neurosurgery Complications
2016
Background To improve the transparency of the local health care system, treatment cost was recently referenced to disease related groups. Treatment quality must be legally documented in a patient registry, in particular for the highly specialized treatments provided by neurosurgery departments. Methods In 2013 we have installed a patient registry focused on cranial neurosurgery. Surgeries are characterized by indication, treatment, location and other specific neurosurgical parameters. Preoperative state and postoperative outcome are recorded prospectively using neurological and sociological scales. Complications are graded by their severity in a therapy-oriented complication score system (C…
La sopravvivenza immediata delle start-up italiane del settore manifatturiero sanitario: un'analisi multilevel
2017
The immediate survival of the Italian start-up businesses in healthcare industry: a multilevel analysis Objectives: The purpose of this contribution is to provide novel evidence about the main determinants of the short-run survival of pharmaceutical and medical device manufacturing start-up firms in Italy. In order to assess both the firm-specific determinants and the observed and unobserved regional and contextual characteristics, we model the three-year firm survival probability by means of a multilevel logistic framework. Methods and Results: The empirical analysis focuses on an internationally comparable database of the population of firms built up and managed by the Italian National In…
The continuing medical education Expectations, motivations and evaluations of the training experience in the Medical Radiologic Technologist
2010
Abstract Every country in the world has the obligatory program: Continuing Medical Education with the aim of maintaining a high standard of professionalism, that is in step with the times. The motivations, expectations and satisfaction that characterize, both the relational and the cognitive plan and the participation of Sanitary Technicians of Medical Radiology training CME courses, are the subjects of this study that involved 100 Radiology technicians. The results highlight areas of satisfaction and give valuable suggestions on how to plan future courses with the highest level of effectiveness.
PODOLOGICAL ASPECTS OF FOOT CARE IN SOCIAL CARE CENTERS
2018
Investigate the necessity for therapeutic foot care and the involvement of a podologist in an interdisciplinary health care team in social care institutions in Latvia. So far, no study has been conducted on the need for therapeutic pediatric care for Social Care Center (SCC) clients in Latvia; it is known that in individual SCC’s where some podologists work part-time, another podologist is invited in specific cases, or clients are taken to a podologist at a medical institution. The study was conducted in 15 Latvian Social Care Centers (SCC), surveying 750 customer feet. People who, for various reasons, are no longer capable of foot care, is a highly necessary specialist who will do it profe…
Physical exercise adherence in Finnish children using a music mat: a pilot study
2020
A growing number of studies has shown that informal musical activities, such as singing, playing an instrument, and musical play at home, are positively associated with children’s health. This paper examines the associations between fourteen 4–6-year-old children’s and their parents’ exercise activity, children’s musical and their exercise adherence when using a music mat over an eight-week period in the home environment. Our results show that most of the children moved on the mat breezily and briskly. The parents assessed that exercises required balance and movement control more than endurance or strength. Spearman’s rank-order correlation showed a strong, positive correlation between the …

I traffici illeciti nel Mediterraneo. Persone, stupefacenti, tabacco
2019
Attraverso la combinazione di ricerca criminologica e giuridico-normativa, e grazie anche alla collaborazione con esperti esterni (studiosi, magistrati, rappresentanti di istituzioni italiane e straniere), la ricerca da cui scaturisce il volume ha indagato le interazioni tra i diversi traffici illeciti e la criminalità organizzata nel bacino del Mediterraneo. In tale area, storicamente cruciale per la mobilità di persone e di beni, l’attenzione si è rivolta in particolare ai fenomeni del traffico e della tratta di persone, del traffico di stupefacenti e del contrabbando di sigarette. I contributi raccolti – unitamente al rapporto criminologico e ai cinque rapporti nazionali accessibili su w…
