abstract background: multiple sclerosis (ms) is a complex inflammatory disease of the central nervous system. despite extensive research, its exact cause is unknown. one of the roles of nurses is discovery and prevention of factors related to the disease. this study aimed to investigate several food items concerning the etiology of ms in a population of ahvaz (iran). materials and methods: this...

In this paper, a learning control system is considered for motion systems that are subject to two types of disturbances; reproducible disturbances, that re-occur each run in the same way, and random disturbances. In motion systems, a large part of the disturbances appear to be reproducible. In the control system considered, the reproducible disturbances are compensated by a learning component c...

This study explored how nursing practitioners perceived inpatients' anxiety, self-esteem, purpose-in-life and multidimensional health locus of control. Seventy-three nurses, 60 third-year and 70 first-year nursing students, and 61 control students not majoring in nursing science estimated how inpatients rated these four psychological states. Their ratings were compared with those given by 121 i...

introduction: spinal malalignment is a common problem in the present societies and forward head posture is one of the most common dysfunction in cervical region. the purpose of the present study is to evaluate effect of stabilization exercises in improving of forward head posture. materials and methods: twenty six female students with forward head posture in age range of 20-27 years old partici...

OBJECTIVES To identify community nurses' perceptions of quality care provision for patients requiring palliative care. DESIGN Semi-structured interviews were conducted with community nurses working within the district nursing service. An adaptation of Flanagan's critical incident technique was employed to elicit factors associated with high or poor quality palliative care. Interviews were tap...

In recent years, an increasing number of research projects investigated whether the central nervous system employs internal models in motor control. While inverse models in the control loop can be identified more readily in both motor behavior and the firing of single neurons, providing direct evidence for the existence of forward models is more complicated. In this paper, we will discuss such ...

conclusions according to the obtained results, the majority of nurses participating in the study had an intermediate level of knowledge and practice of infection control. there is a need to develop a system of continuous education for all the categories of nursing staff. background basic infection control measures in any nursing setup can reduce the rates of healthcare-associated infections. re...

background: we observed the clinical effects of comprehensive nursing intervention pattern in 23g minimally invasive vitreous surgery according to the comprehensive nursing intervention table developed by our hospital, which would supply a basis for its clinical application. methods: in this prospective study, we followed 120 patients undergoing 23g minimally invasive vitreous surgery from xuzh...

We introduce the Learning Feed-Forward Control configuration. In this configuration, a B-spline neural network is contained, which suffers from the curse of dimensionality. We propose a method to avoid the occurrence of this problem. 1 Introduction In order to design a conventional feedback controller, like a state-feedback controller, detailed knowledge of the process under control is required...
