Visual servoing of continuum robots: Methods, challenges, and prospects.

Background: Recent advancements in continuum robotics have accentuated developing efficient and stable controllers to handle shape deformation and compliance. The control of continuum robots (CRs) using physical sensors attached to the robot, particularly in confined spaces, is difficult due to their limited accuracy in three-dimensional deflections and challenging localisation. Therefore, using non-contact imaging sensors finds noticeable importance, particularly in medical scenarios.

Iranian staff nurses' views of their productivity and management factors improving and impeding it: a qualitative study.

As the biggest proportion of hospital personnel, Iranian nurses have a major role in providing quality care to patients. Nursing managers and nurses no longer feel that nurses' work is valued and they are concerned about their productivity. Nurses' views about productivity and management factors affecting it have been identified as the most important aspects affecting productivity.

Iranian staff nurses' views of their productivity and human resource factors improving and impeding it: a qualitative study.

Background: Nurses, as the largest human resource element of health care systems, have a major role in providing ongoing, high-quality care to patients. Productivity is a significant indicator of professional development within any professional group, including nurses. The human resource element has been identified as the most important factor affecting productivity.
