BACKGROUND We performed a multicenter controlled trial to assess the knowledge and attitude (KA) about cardiopulmonary resuscitation (CPR) among secondary school children in a district in Malaysia. METHODS This was a prospective intervention study. The primary endpoint of the study was to determine the level of KA about resuscitation after CPR training. The six schools and classes from select...

We applied the strength-energy model of self-control to understand the relationship between self-control and young athletes' behavioral responses to taking illegal performance-enhancing substances, or "doping." Measures of trait self-control, attitude and intention toward doping, intention toward, and adherence to, doping-avoidant behaviors, and the prevention of unintended doping behaviors wer...

This paper deals with the applicability of Robust Adaptive Control to the attitude motion control of large spacecraft. Large spacecraft and space structures, such as large communication satellites and the ISS (International Space Station), have been constructed on orbit. However dynamic characteristics of these structures can not be fully verified on the ground because of their size, mass and f...

Control laws for an integrated power/attitude control system (IPACS) for a satellite using variable-speed singlegimbal control moment gyroscopes (VSCMGs) are introduced. Whereas the wheel spin rates of the conventional CMGs are constant, the VSCMGs are allowed to have variable speeds. Therefore, VSCMGs have extra degrees of freedom and can be used to achieve additional objectives, such as energ...

Flywheels can exert torque that alters the Station's attitude motion, either intentionally or unintentionally. A design is presented for a once planned experiment to contribute torque for Station attitude control, while storing or discharging energy. Two contingencies are studied: the abrupt stop of one rotor while another rotor continues to spin at high speed, and energy storage performed with...

asthma affects an estimated 300 million people worldwide. poor compliance with the prescribed medication leads to increased mortality and morbidity. various determinants of compliance have been described. the purpose of this study was to determine factors that can influence patients' compliance with prescribed metered dose inhaler drugs. 179 patients with diagnosis of asthma were selected from ...

Abstract: In this paper, we consider the coordinated attitude control problem without velocity measurements. Based on the recently introduced unit quaternion output feedback for the attitude tracking of a rigid body, we present a class of decentralized coordinated control laws to solve the alignment problem for a group of spacecraft within a formation without velocity measurements. The approach...

Background: Improvement in the performance of health care workers is an important aspect of infection control in the health care settings. Nursing students are more exposed to infections during clinical experience so they need to improve their performance related to infection control measures. Aim: This study was conducted to assess of knowledge, practice and attitude of internship nursing stud...
