The competitiveness of public transport

Examining the competitiveness of public transport plays an important role because through public transport, the transport of passengers to schools, public healthcare establishments and work is ensured. In addition, transportation for vulnerable groups of passengers (students, seniors) is provided. On the other hand, public transport constitutes a financial burden on public budgets. The aim of this paper is to point out that public transport does not have an equal status in the transport market within the European Union. In the states of Central and Eastern Europe, public transport had a dominant position in the transport market in the 90s. Nowadays, the market share is declining, particularly in the bus transport, with the rising costs for public budgets regarding an increase in individual motoring. The aim of this paper is to highlight the possibilities of increasing the competitiveness of public transport by integrating different components of public transport. Another aim is to define the possibilities of financing public transport.Agentura na podporu vyskumu a vyvoja [SK - PL - 2015 - 0019

Young Adult Drivers: Simulated Behaviour in a Car-following Situation

This paper provides a description of driver testing in a simulator. As young drivers are more susceptible to collisions, this was done to determine how young drivers behaved in simulated road situations on a motorway. One of the traffic safety concerns is the failure to keep a proper distance from the vehicle in front, which may result in a rearend collision. The tests simulated car-following situations in which the preceding vehicle performed emergency braking. The experiments were conducted for two scenario variants using different distances from the vehicle in front. The drivers could perform the following emergency manoeuvres: braking with steering away or only braking. The driver response times were compared and analysed statistically. The results were used to determine the emergency manoeuvres performed by the drivers in the simulated road situations. The study reveals that the vehicle surroundings may have a considerable influence on the type of emergency manoeuvres and the driver response time. </p

LEE: A photorealistic virtual environment for assessing driver-vehicle interactions in self-driving mode

Photorealistic virtual environments are crucial for developing and testing automated driving systems in a safe way during trials. As commercially available simulators are expensive and bulky, this paper presents a low-cost, extendable, and easy-to-use (LEE) virtual environment with the aim to highlight its utility for level 3 driving automation. In particular, an experiment is performed using the presented simulator to explore the influence of different variables regarding control transfer of the car after the system was driving autonomously in a highway scenario. The results show that the speed of the car at the time when the system needs to transfer the control to the human driver is critical

A bronze socketed axe from Falejówka

The article is devoted to the find of a bronze socketed axe discovered in 2013 in Falejówka (Sanok district). The find was made on the top of Mount Wroczeń, several meters from the hoard of bronze items (Falejówka, hoard II), dated to HaA1. This artefact belongs to the so-called “beaked” or “horned” axes, but none of the numerous specimens of this type is an exact equivalent of the discussed find. Stylistic features – primarily the characteristic trident motif decorating it, which occurs on axes discovered mainly in today's Hungary – allow the item from Falejówka to be dated HaA1-HaB1. The quality of the casting proves that the axe was made with good knowledge of the mould technology and the processes of smelting and pouring the liquid alloy, using bronze with a low tin content. As for its composition, metals derived from sulphide ores, mainly antimony, have also been identified

Driver’s reaction time in a simulated, complex road incident

This paper presents an overview of research on the behaviour of drivers in simulated accident situations. The research was carried out by the authors of this work as a part of a research N N509 549 040 funded by the National Science Centre including new accident situations. The paper presents a description of the methodology and implementation of research on a track. During the tests, the simulation concerns about an accident risk situation involving pedestrians and passenger cars intruding the road area. In contrast to earlier research carried out by the authors, the scenario included the possibility of a pedestrian ‘entering’ from behind a curtain, both from the left and from the right sides of the road. This was possible thanks to a specially developed test stand. The paper analyses the values of driver’s reaction times characteristic to driver’s impact on: acceleration control pedals, service brake and steering wheel. In addition to the determination of average reaction time values and the regression line for the test group of 30 drivers, the assessment of the frequency of drivers taking individual defensive reactions was carried out. Keywords: traffic safety; collision; road accidents; regression equation; simulation. First published online: 09 May 201

Living with Phenylketonuria: lessons from the PKU community

Introduction: We report the practical, social and psychological issues of living with phenylketonuria (PKU) from one of the largest surveys that has been completed by both adults with PKU and parents/caregivers of children. Methods: In the UK, parents/caregivers of children and adults with PKU were invited to complete an online survey between November 2017 to January 2018 by the NSPKU (National Society for Phenylketonuria). Results: 631 participants (adults, n=338; parents/caregivers of children, n=293) with PKU completed the questionnaire. Problems experienced by children with PKU were: difficulty with maintaining focus (48%,n=114/236), educational difficulties (28%, n=67/236), anxiety or depression (29%, n=68/236), and gastrointestinal symptoms (34%, n=97/282). Fifty one per cent (n=120/236) described social exclusion; 17% (n=41/236) had relationship issues with friends or family. Problems experienced by adults were: depression or anxiety (52%, n=148/286), difficulty maintaining focus (54%, n=154/286), and low mood (54%, n=180/334). Difficulties were experienced with relationships (34%, n=96/286); social exclusion (44%, n=126/286); and gastrointestinal issues (n=34%, n=112/334). Common medications used included antidepressants (40%, n=131/331) and anxiolytics (18%, n=60/334). Discussions: Adults with PKU or caregivers/parents of children identified significant neurocognitive, mental health and general health issues. Limits on socialisation, perception of social isolation and dietary stigma are major obstacles which are difficult to overcome with conventional dietary management

Impact of long-term elosulfase alfa treatment on respiratory function in patients with Morquio A syndrome

OBJECTIVE: To present long-term respiratory function outcomes from an open-label, multi-center, phase 3 extension study (MOR-005) of elosulfase alfa enzyme replacement therapy (ERT) in patients with Morquio A syndrome. METHODS: In part 1 of MOR-005, patients initially randomized to ERT in the 24-week pivotal study (MOR-004) remained on their regimen (2.0 mg/kg/week or every other week); placebo patients were re-randomized to one of the two regimens. During part 2, all patients received elosulfase alfa 2.0 mg/kg/week. Respiratory function was one of the efficacy endpoints evaluated in MOR-005. Change from MOR-004 baseline to 120 weeks of treatment for the combined population was determined and compared with results from untreated patients from a Morquio A natural history study (MorCAP). RESULTS: Maximum voluntary ventilation (MVV) improved up to week 72 and then stabilized; forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1) increased continuously over 120 weeks. Mean increases in the modified per-protocol population was 9.2 % for FVC, 8.8 % for FEV1, and 6.1 % for MVV after 120 weeks. All patients ≤14 years showed respiratory improvements, presumably in part related to growth; however, these were greater in treated patients. For those >14 years, treated patients showed improvements, while deterioration occurred in untreated. Altogether, the improvements were significantly greater (P < 0.05) in treated patients. CONCLUSIONS: Long-term ERT is associated with sustained improvements in respiratory function in Morquio A. In younger patients (≤14 years), some improvement may be ascribed to growth. In older patients, other mechanisms, e.g., decreased glycosaminoglycan storage, are likely involved

Long-term endurance and safety of elosulfase alfa enzyme replacement therapy in patients with Morquio A syndrome

Long-term efficacy and safety of elosulfase alfa enzyme replacement therapy were evaluated in Morquio A patients over 96weeks (reaching 120weeks in total from pre-treatment baseline) in an open-label, multi-center, phase III extension study. During this extension of a 24-week placebo-controlled phase III study, all patients initially received 2.0mg/kg elosulfase alfa either weekly or every other week, prior to establishment of 2.0mg/kg/week as the recommended dose, at which point all patients received weekly treatment. Efficacy measures were compared to baseline of the initial 24-week study, enabling analyses of changes over 120weeks. In addition to performing analyses for the entire intent-to-treat (ITT) population (N=173), analyses were also performed for a modified per-protocol (MPP) population (N=124), which excluded patients who had orthopedic surgery during the extension study or were non-compliant with the study protocol (as determined by ≥20% missed infusions). Six-minute walk test (6MWT) was the primary efficacy measure; three-minute stair climb test (3MSCT) and normalized urine keratan sulfate (uKS) were secondary efficacy measures. Mean (SE) change from baseline to Week 120 in 6MWT distance was 32.0 (11.3)m and 39.9 (10.1)m for patients receiving elosulfase alfa at 2.0mg/kg/week throughout the study (N=56) and 15.1 (7.1)m and 31.7 (6.8)m in all patients combined, regardless of dosing regimen, for the ITT and MPP populations, respectively. Further analyses revealed that durability of 6MWT improvements was not impacted by baseline 6MWT distance, use of a walking aid, or age. Mean (SE) change at Week 120 in the 3MSCT was 5.5 (1.9) and 6.7 (2.0)stairs/min for patients receiving elosulfase alfa at 2.0mg/kg/week throughout the study and 4.3 (1.2) and 6.8 (1.3)stairs/min in all patients combined, regardless of dosing regimen, for the ITT and MPP populations, respectively Across all patients, mean (SE) change at Week 120 in normalized uKS was -59.4 (1.8)% and -62.3 (1.8)% in the ITT and MPP populations, respectively. In the absence of a placebo group, significance of the sustained improvements could not be evaluated directly. However, to provide context for interpretation of results, comparisons were performed with untreated patients from a Morquio A natural history study. In contrast to the results of the extension study, the untreated patients experienced constant uKS levels and a gradual decline in endurance test results over a similar period of time. Differences from the untreated natural history study patients were significant for 6MWT, 3MSCT, and uKS outcomes for the cohort of patients receiving optimal dosing throughout the study and for all cohorts pooled together, for both ITT and MPP populations (P<0.05). Safety findings were consistent with those of the initial 24-week study, with no new safety signals identified

Da fotografia como arte à arte como fotografia: a experiência do Museu de Arte Contemporânea da USP na década de 1970

Este ensaio visa sistematizar os primeiros resultados de uma pesquisa, ainda em curso, sobre o processo de legitimação da fotografia pelo sistema de arte no Brasil, cujo foco principal é o museu. Os museus de arte da cidade de São Paulo foram escolhidos para dar início a essa investigação. Primeiramente, será abordada, em linhas gerais, a presença da fotografia no Museu de Arte Moderna de São Paulo e na Bienal de São Paulo, dada a vinculação de origem do Museu de Arte Contemporânea com essas duas instituições paulistanas. Na seqüência será analisada a formação do acervo fotográfico do Museu de Arte Contemporânea da Universidade de São Paulo durante a década de 1970. Por fim, esse percurso permitirá observar que a atuação de Walter Zanini, o primeiro diretor do Museu, e as particularidades da posição do MAC-USP no sistema de arte no Brasil naquele período resultaram no entendimento da fotografia prioritariamente no âmbito da arte contemporânea de caráter experimental e não como obra de arte autônoma, segundo os princípios da chamada fotografia artística.This article presents the first findings of a research still under development about the process of legitimation of photography as a kind of art by the artistic scene in Brazil. The art museums of the city of São Paulo were chosen for starting that research. Initially, we will be investigating the presence of photography at the Contemporary Art Museum of São Paulo and at the Biennial of São Paulo, as the origin of the Contemporary Art Museum is tided to those two institutions. Following, the arrangement of the photographic technical reserve of the Contemporary Art Museum in the 1970s will be analyzed. This study will be focusing on the work of Walter Zanini, as the first director of the museum, and on the particularities of MAC-USP position in the art system in Brazil which resulted in the understanding of photography as belonging to the sphere of contemporary art in an experimental way and not as an autonomous work of art, according to the principals of the so called artistic photography
