Authors: O’Brien Myles W. , Shields Christopher A. , Campbell Kristin L. , Crowell Sandra J. , Fowles Jonathon R.
Published: August 2019

Purpose: We assessed the perceptions and practices of physical activity counselling and exercise prescription of physiotherapists in Nova Scotia. Method: A total of 146 physiotherapists in Nova Scotia completed an online self-reflection survey regarding their current practice of, confidence in, barriers to, and facilitators of providing physical activity and exercise (PAE) counselling to their patients. Results: Physiotherapists included physical activity counselling and exercise content in 85% of patient counselling appointments. They reported a high level of confidence (> 90%) in providing PAE information and answering patients’ PAE questions and moderate confidence in their patients’ abilities to maintain PAE over the long term (73%) and to follow through on their PAE recommendations (66%). Patients’ interest in PAE was the greatest barrier to providing PAE counselling. The physiotherapists reported being most comfortable when prescribing exercise for patients with musculoskeletal conditions and least comfortable with patients with cancer, insulin-dependent diabetes, and respiratory conditions. Most physiotherapists (71%) reported being interested in pursuing further education or training in PAE counselling and prescription. Conclusions: The physiotherapists frequently recommended PAE to their patients, had moderate confidence in their patients’ ability to follow through on their advice, and experienced patients’ disinterest in PAE as the greatest barrier to providing PAE counselling. The results of this study suggest a desire by physiotherapists for educational training opportunities, which we recommend be focused on providing behavioural strategies and further information to help overcome patient-focused barriers; this will help patients adopt and maintain physically active lifestyles.

Published: August 2019

Masalah transportasi terjadi ketika tingkat arus masuk kendaraan melebihi laju arus keluar kendaraan di satu tempat. Berbagai faktor mendukung terjadinya masalah kemacetan, salah satunya persimpangan yang padat dan mengakibatkan keterlambatan kendaraan sehingga arus masuk tidak sesuai dengan arus keluar. Pengaturan aliran lalu lintas di persimpangan biasanya menggunakan sinyal lampu lalu lintas yang berfungsi untuk menghentikan aliran lalu lintas ke arah tertentu dan memungkinkan arus dari arah lain pergi. Penulis mengusulkan menggunakan pemrograman stokastik dua tahap untuk menghasilkan model baru dalam penjadwalan rencana waktu sinyal yang efisien untuk meminimalkan penundaan kendaraan yang diharapkan.

 

Transportation problems occur when the level of vehicle inflows exceeds the rate of vehicle outflow in one place. Various factors support the occurrence of congestion problems, one of which intersections are dense and result in vehicle delays so the incoming currents aren’t in accordance with the outflow. Traffic flow arrangements at intersections usually use traffic light signals that serve to stop traffic flow in certain directions and allowing currents from other directions to go.
