Using of information and communication technologies In the health sector improve considerably the functioning of healthcare processes and medical-administrative management, all of which it contributes to greater hospital efficiency and competitive performance of the institutions. This research addresses the existing problem with the design of the network infrastructure of the Medical Surgical Research Center (CIMEQ), which affects the substantive processes of the institution, such as patient management and the transmission of medical images. The objective of the research is to redesign the CIMEQ network infrastructure, which allows increase its performance and security. The research has a quantitative approach, with a descriptive scope, of a retrospective type and an experimental design, of longitudinal cut. Scientific methods of modeling and documentary analysis were used. As a result, the CIMEQ local area network infrastructure was redesigned, through segmentation methods that allowed dynamic workgroups to be created, take advantage of the benefits of installed manageable equipment and the implementation of new firewalls. The segmentation proposal obtained, through virtual local area networks, application of security measures in the layer 2 and layer 3 of the OSI model and bandwidth management through the implementation of quality of service for applications that require priority in network traffic, improved the performance and security of the CIMEQ network infrastructure, which impacts in a greater competitive performance and hospital efficiency(AU)

Influence Factors for Competitive Performance of Alpine Skiers in the View of Biomechanics / 医用生物力学

Under the background of technological assistance to prepare for the Beijing Winter Olympics in China, the biomechanical research highlights and the latest achievements related to competitive performance of alpine skiers in recent years were systematically analyzed in this paper, so as to determine biomechanical factors affecting competitive performance of alpine skiers, including aerodynamic drag, frictional forces, ground reaction force (GRF), energy dissipation, turn radius, trajectory of the skis and/or center of mass (COM). In addition, biomechanical differences in turn techniques, multiple turns connections and abilities of individuals were also considered as important factors affecting the alpine skiing performance. In the case of slalom and giant slalom events, the earlier initiation of turns, longer path length and trajectory, earlier and smoother application of GRF, and carbene technique carving to reduce the ski-snow friction and thereby dissipate energy should be used to improve sports performance. During speed skiing, minimizing the exposed frontal area and positioning the arms close to the body can reduce the energy loss caused by aerodynamic drag, thereby improving sports performance. Top-level alpine skiers will always perform well on different courses, terrains and snow conditions during the race. Excellent alpine ski performance from a biomechanical perspective includes the efficient use of potential energy, minimizing ski-snow friction and aerodynamic drag, choosing optimal trajectory and maintaining high-speed skiing. Individual tactics and techniques should be valued in training and competition. For better results, the same performance on multiple sections and on different terrains is more important than excellence in individual sections and specific conditions.

Previous participation in FIFA World-Cup: the key to success?

This qualitative-descriptive investigation examining the influence exerted by experienced soccer-players on the ranking obtained from the four best-ranked by their teams in the last four FIFA World Cups (WC). They were divided into experienced-players (at least one WC participation [+1WC]) or non-experienced players (no previous participation [1WC]). Thereafter, they were classified according to their contribution in each of the playoff matches in a given WC: STARTER (started all matches); START/SUBST (started at least one match); SUBST/BENCH (did not start any matches, but replaced a player in at least one match); and BENCH (did not participate in matches). The sample was composed of 33.7% experienced and 66.3% non-experienced players. The number of players +1WC in finalist teams was significantly higher than in the non-finalist teams (p<0.05). In addition, when compared with the non-finalist teams, the finalists presented significantly higher number of players STARTER with +1WC (p<0.05). Possibly, the selection of experienced players to participate in WC may be an effective strategy to achieve better competitive performance
