Vehicle emission certification is evaluated under laboratorial conditions, where vehicles perform a standard driving cycle in controlled conditions leading to several critics, which have resulted in the implementation of the Worldwide harmonized Light Vehicle Test Procedure (WLTP) and the Real Driving Emissions (RDE) testing procedure, as a complementary certification procedure. RDE is still under debate since boundary conditions; evaluation and trip selection methods are still being studied to allow test reproducibility. Currently, the official data analysis method uses the moving average window (MAW_EC), based on the WLTP CO emissions for trip validity evaluation (RDE package 4) and emissions (RDE package 3).

Main factors addressed by the regulation include the share of driving operation, ambient temperature range, altitude and elevation difference. However, RDE is still debatable since not only boundary conditions but also the evaluation methods and trip selection are being discussed together with a carbon dioxide (CO) regulation, which is planned to be implemented in the short term.

In this sense, this research work analyzes and quantifies the impacts of cold start in urban context using naturalistic driving data. Furthermore, an assessment of the influence of ambient temperature on the percentage of time spent on cold start was also performed.

For some patients undergoing treatment, continuing to be professionally active is challenging especially considering that work fosters a purpose in life, a sense of contribution, distraction, and self-esteem, which aids in physical, cognitive, emotional, and interpersonal recovery. Within this context, the aim is to describe the limitations found in individuals with cancer, who have maintained their work activities in private service during radiotherapy treatment, through a descriptive study and a quantitative approach.

Method: A descriptive, exploratory, cross-sectional and quantitative study conducted with 137 CHAs. Data were collected through a questionnaire and interview guided by the health surveillance software called SIMOSTE (Health Monitoring System of Nursing Workers), following the ethical codes of the current law.
Objective To understand the perception of nurse managers about the relationship between nursing workers health and patient safety. Method A qualitative survey was conducted using the social phenomenology approach of Alfred Schütz, accomplished through individual interviews with nine nurse managers from five Brazilian university hospitals. Results Nurse managers' perception of the relationship between nursing workers health and patient safety was evidenced in the following categories: "The suffering to balance workers health and patient safety" and "Interventions in everyday work life".

Air quality in urban centers constitutes a challenge ahead for most cities. For this reason, the objective of this research work was to evaluate the impacts of changing traffic-related parameters on particulate matter (PM) concentration for several hierarchical street levels using real-world data for the city of Lisbon, Portugal. For that purpose, 2014 data regarding meteorological conditions, traffic volumes, typical vehicle speed, and a vehicle representative of the fleet was used in an air quality dispersion model (CALINE4).

Method: This is a quantitative, exploratory and descriptive study realized in a teaching hospital in the west region of the city of São Paulo.
Results: From the SIMOSTE, 1.
This is an exploratory, descriptive and quantitative study, based on the following categories: work process, workloads and fatigue in a teaching hospital in Curitiba in the southern region of Brazil. The article characterizes the load and stress experienced in a university hospital, based on a previous study entitled "System for monitoring the health of nursing workers" (SIMOSTE). The results show that females were the most affected (85.
