It is a documented fact that if work activity entails prolonged static postures, repetitive movements and the assuming of incongruous positions, skeletal muscle disorders can arise. MATERIALS AND METHODS. 100 surgeons (74 M 26 F), average age 40.1, completed a questionnaire regarding work posture, fatigue and pain experienced after working in the operating theatre. RESULTS. 75% work standing up, the average operation duration time is 4.3 hours (max 8 hours); 50% are unable to change position during the operation and the average time spent in a fixed position is 2 hours (max 6 hours). 58% of surgeons report the onset of myoarticular pain after an average of 4.3 hours (1-8) of surgical activity, principally regarding the cervical and lumbar rachis. Only 9% know the ergonomic guidelines for surgery and only 3% apply them. CONCLUSIONS: Applying the ergonomic guidelines, modifying surgical equipment and increasing posture awareness could help improve comfort while operating and reduce skeletal muscle disorder
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
