    Robotic surgery is a reality. In order to to understand how new robots work is interesting to know the history of ancient (see part i) and modern robotics. The desire to design automatic machines imitating humans continued for more than 4000 years. Archytas of Tarentum (at around 400 a.C.), Heron of Alexandria, Hsieh-Fec, Al-Jazari, Bacon, Turriano, Leonardo da Vinci, Vaucanson o von Kempelen were robot inventors. At 1942 Asimov published the three robotics laws. Mechanics, electronics and informatics advances at XXth century developed robots to be able to do very complex self governing works. At 1985 the robot PUMA 560 was employed to introduce a needle inside the brain. Later on, they were designed surgical robots like World First, Robodoc, Gaspar o Acrobot, Zeus, AESOP, Probot o PAKI-RCP. At 2000 the FDA approved the da Vinci Surgical System (Intuitive Surgical Inc, Sunnyvale, CA, USA), a very sophisticated robot to assist surgeons. Currently urological procedures like prostatectomy, cystectomy and nephrectomy are performed with the da Vinci, so urology has become a very suitable speciality to robotic surgery.

    Robotic surgery is the newst technologic option in urology. To understand how new robots work is interesting to know their history. The desire to design machines imitating humans continued for more than 4000 years. There are references to King-su Tse (clasic China) making up automaton at 500 a. C. Archytas of Tarentum (at around 400 a.C.) is considered the father of mechanical engineering, and one of the occidental robotics classic referents. Heron of Alexandria, Hsieh-Fec, Al-Jazari, Roger Bacon, Juanelo Turriano, Leonardo da Vinci, Vaucanson o von Kempelen were robot inventors in the middle age, renaissance and classicism. At the XIXth century, automaton production underwent a peak and all engineering branches suffered a great development. At 1942 Asimov published the three robotics laws, based on mechanics, electronics and informatics advances. At XXth century robots able to do very complex self governing works were developed, like da Vinci Surgical System (Intuitive Surgical Inc, Sunnyvale, CA, USA), a very sophisticated robot to assist surgeons.

    This study aims (1) to investigate the feasibility of robot-assisted penetrating keratoplasty (PK) using the new Da Vinci Xi Surgical System and (2) to report what we believe to be the first use of this system in experimental eye surgery. Robot-assisted PK procedures were performed on human corneal transplants using the Da Vinci Xi Surgical System. After an 8-mm corneal trephination, four interrupted sutures and one 10.0 monofilament running suture were made. For each procedure, duration and successful completion of the surgery as well as any unexpected events were assessed. The depth of the corneal sutures was checked postoperatively using spectral-domain optical coherence tomography (SD-OCT). Robot-assisted PK was successfully performed on 12 corneas. The Da Vinci Xi Surgical System provided the necessary dexterity to perform the different steps of surgery. The mean duration of the procedures was 43.4 ± 8.9 minutes (range: 28.5-61.1 minutes). There were no unexpected intraoperative events. SD-OCT confirmed that the sutures were placed at the appropriate depth. We confirm the feasibility of robot-assisted PK with the new Da Vinci Surgical System and report the first use of the Xi model in experimental eye surgery. Operative time of robot-assisted PK surgery is now close to that of conventional manual surgery due to both improvement of the optical system and the presence of microsurgical instruments. Experimentations will allow the advantages of robot-assisted microsurgery to be identified while underlining the improvements and innovations necessary for clinical use.

    The aim of the study was to determine if the concept of face and construct validity may apply to the SurgicalSim Educational Platform (SEP) "robot" simulator. The SEP robot simulator is a virtual reality (VR) simulator aiming to train users on the Da Vinci Surgical System. To determine the SEP's face validity, two questionnaires were constructed. First, a questionnaire was sent to users of the Da Vinci system (reference group) to determine a focused user-group opinion and their recommendations concerning VR-based training applications for robotic surgery. Next, clinical specialists were requested to complete a pre-tested face validity questionnaire after performing a suturing task on the SEP robot simulator. To determine the SEP's construct validity, outcome parameters of the suturing task were compared, for example, relative to participants' endoscopic experience. Correlations between endoscopic experience and outcome parameters of the performed suturing task were tested for significance. On an ordinal five-point, scale the average score for the quality of the simulator software was 3.4; for its hardware, 3.0. Over 80% agreed that it is important to train surgeons and surgical trainees to use the Da Vinci. There was a significant but marginal difference in tool tip trajectory (p = 0.050) and a nonsignificant difference in total procedure time (p = 0.138) in favor of the experienced group. In conclusion, the results of this study reflect a uniform positive opinion using VR training in robotic surgery. Concepts of face and construct validity of the SEP robotic simulator are present; however, these are not strong and need to be improved before implementation of the SEP robotic simulator in its present state for a validated training curriculum to be successful .

    Handedness, or the inherent dominance of one hand's dexterity over the other's, is a factor in open surgery but has an unknown importance in robot-assisted surgery. We sought to examine whether the robotic surgery platform could eliminate the effect of inherent hand preference. Residents from the Urology and Obstetrics/Gynecology departments were enrolled. Ambidextrous and left-handed subjects were excluded. After completing a questionnaire, subjects performed three tasks modified from the Fundamentals of Laparoscopic Surgery curriculum. Tasks were performed by hand and then with the da Vinci robotic surgical system (Intuitive Surgical, Sunnyvale, California). Participants were randomized to begin with using either the left or the right hand, and then switch. Left:right ratios were calculated from scores based on time to task completion. Linear regression analysis was used to determine the significance of the impact of surgical technique on hand dominance. Ten subjects were enrolled. The mean difference in raw score performance between the right and left hands was 12.5 seconds for open tasks and 8 seconds for robotic tasks (Probot tasks, respectively (Probotic and open approaches for raw time scores (Phand, prior robotic experience, and comfort level. These findings remain to be validated in larger cohorts. The robotic technique reduces hand dominance in surgical trainees across all task domains. This finding contributes to the known advantages of robotic surgery.

    Health technology assessment (HTA) is frequently used when a new and expensive technology is being introduced into clinical practice. This certainly is the case with the da Vinci surgical robot, with costs ranging from $1 to $2.5 million for each unit. This systematic review documents major variability in the reported cost evaluation studies of da Vinci robot-assisted operations compared with those performed by the direct manual laparoscopic approach. Published studies in the English language related to the period 2000-2010 were searched using economic and clinical electronic databases. All 11 reports included some form of cost analysis, which made it possible for the authors to extract information on certain specific economic outcomes: operating room time, hospital stay, and total costs. With the exception of two studies, the reported operating room time was higher with the robotic approach than with manual laparoscopic surgery, and the hospital stay was the same for the two techniques. Robotic surgery is significantly more expensive if the purchase and maintenance costs of the robot system are included in the total costs. Only 3 of the 11 publications included these costs. The disadvantage of robotic surgery is its higher costs related to purchase and maintenance of technology and its longer operating room time. However, emerging evidence shows that operating room time decreases with experience using the robot. From the HTA viewpoint, the result of this review is that the jury still is out on the HTA of da Vinci-assisted robotic surgery.

    Conclusion: Minimally invasive surgery is the trend of the future. Robot-assisted laparoscopic surgery is a new technique for myomectomy. This robotic system provides a three-dimensional operative field and an easy-to-use control panel, which may be of great help when applying the suturing techniques and may shorten the learning curve. More experience with and long-term follow-up of robotic surgery may be warranted to further validate the role the robot-assisted approach in gynecologic surgery.

    To report our initial experience on robot-assisted radical nephroureterectomy, using the da Vinci Xi robotic system without patient or port repositioning. The patients were in a modified flank position. A Bugbee electrode was used to cauterize and mark the ureteral orifice, aiding in the final robotic excision of the distal ureter. For the first step of the procedure, the second robotic arm holds the scope, the fourth robotic arm holds Port #1 (monopolar curved scissors), the first robotic arm holds Port #2 (Fenestrated bipolar forceps), and the third robotic arm holds Port #4 (Prograsp forceps). After completion of nephrectomy, all robotic arms were released and reconfigured. In the new setting, the third robotic arm and second robotic arm were switched between the camera port and the fourth port. The first port remained working with the monopolar curved scissors whereas Prograsp forceps was moved to the second port and fenestrated bipolar forceps was moved to the third port. Two patients underwent 2 successful radical nephroureterectomies with the above-mentioned technique. The console time for the first patient was 150 minutes whereas the estimated blood loss was 200 mL. The console time and blood loss for the second patient were 140 minutes and 300 mL, respectively. The hospitalization time and catheter removal time were 3 days for both patients and no complications were observed. The use of the da Vinci Xi robotic system enabled us to perform both nephrectomy and distal ureterectomy and/or bladder cuff excision without any repositioning of the patient or trocars.

    What's known on the subject? and What does the study add? Numerous urological procedures can now be performed with robotic assistance. Though not definitely proven to be superior to conventional laparoscopy or traditional open surgery in the setting of a randomised trial, in experienced centres robot-assisted surgery allows for excellent surgical outcomes and is a valuable tool to augment modern surgical practice. Our review highlights the depth of history that underpins the robotic surgical platform we utilise today, whilst also detailing the current place of robot-assisted surgery in urology in 2011. The evolution of robots in general and as platforms to augment surgical practice is an intriguing story that spans cultures, continents and centuries. A timeline from Yan Shi (1023-957 bc), Archytas of Tarentum (400 bc), Aristotle (322 bc), Heron of Alexandria (10-70 ad), Leonardo da Vinci (1495), the Industrial Revolution (1790), 'telepresence' (1950) and to the da Vinci(®) Surgical System (1999), shows the incredible depth of history and development that underpins the modern surgical robot we use to treat our patients. Robot-assisted surgery is now well-established in Urology and although not currently regarded as a 'gold standard' approach for any urological procedure, it is being increasingly used for index operations of the prostate, kidney and bladder. We perceive that robotic evolution will continue infinitely, securing the place of robots in the history of Urological surgery. Herein, we detail the history of robots in general, in surgery and in Urology, highlighting the current place of robot-assisted surgery in radical prostatectomy, partial nephrectomy, pyeloplasty and radical cystectomy. © 2011 THE AUTHORS.

    This study explored the rather rapid adoption of a new surgical device - the da Vinci robot - in the Netherlands despite the high costs and its controversial clinical benefits. We used the concept 'affordances' as a conceptual-analytic tool to refer to the perceived promises, symbolic meanings, and utility values of an innovation constructed in the wider social context of use. This concept helps us empirically understand robot adoption. Data from 28 in-depth interviews with diverse purposively-sampled stakeholders, and from medical literature, policy documents, Health Technology Assessment reports, congress websites and patients' weblogs/forums between April 2009 and February 2014 were systematically analysed from the perspective of affordances. We distinguished five interrelated affordances of the robot that accounted for shaping and fulfilling its rapid adoption: 'characteristics-related' affordances such as smart nomenclature and novelty, symbolising high-tech clinical excellence; 'research-related' affordances offering medical-technical scientific excellence; 'entrepreneurship-related' affordances for performing better-than-the-competition; 'policy-related' affordances indicating the robot's liberalised provision and its reduced financial risks; and 'communication-related' affordances of the robot in shaping patients' choices and the public's expectations by resonating promising discourses while pushing uncertainties into the background. These affordances make the take-up and use of the da Vinci robot sound perfectly rational and inevitable. This Dutch case study demonstrates the fruitfulness of the affordances approach to empirically capturing the contextual dynamics of technology adoption in health care: exploring in-depth actors' interaction with the technology while considering the interpretative spaces created in situations of use. This approach can best elicit real-life value of innovations, values as defined through the eyes of (potential) users

    Tough Al-alginate/poly(N-isopropylacrylamide) (PNIPAM) hydrogel has been synthesized by introducing an interpenetrating network with hybrid physically cross-linked alginate and chemically cross-linked PNIPAM. Varying the concentration of AlCl3 regulates the mechanical properties of the tough hydrogel and tunes its lower critical solution temperature (LCST) as well. The tough Al-alginate/PNIPAM exhibits 6.3 ± 0.3 MPa of compressive stress and 9.95 of uniaxial stretch. Tunability of LCST is also achieved in a wide range within 22.5-32 °C. A bending beam actuator and a four-arm gripper made of bilayer (Na-alginate/PNIPAM)/(Al-alginate/PNIPAM) hydrogel as prototype of all-hydrogel soft robotics are demonstrated. A finite element (FE) simulation model is developed to simulate the deformation of the soft robotics. The FE simulation not only reproduces the deformation process of performed experiments but also predicts more complicated devices that can be explored in the future. This work broadens the application of temperature-responsive PNIPAM-based hydrogels.

    We report our initial experiences of robot-assisted cardiac surgery using the da Vinci Surgical System. Between February 2010 and March 2014, 50 consecutive patients underwent minimally invasive robot-assisted cardiac surgery. Robot-assisted cardiac surgery was employed in two cases of minimally invasive direct coronary artery bypass, 17 cases of mitral valve repair, 10 cases of cardiac myxoma removal, 20 cases of atrial septal defect repair, and one isolated CryoMaze procedure. Average cardiopulmonary bypass time and average aorta cross-clamping time were 194.8±48.6 minutes and 126.1±22.6 minutes in mitral valve repair operations and 132.0±32.0 minutes and 76.1±23.1 minutes in myxoma removal operations, respectively. During atrial septal defect closure operations, the average cardiopulmonary bypass time was 128.3±43.1 minutes. The median length of stay was between five and seven days. The only complication was that one patient needed reoperation to address bleeding. There were no hospital mortalities. Robot-assisted cardiac surgery is safe and effective for mitral valve repair, atrial septal defect closure, and cardiac myxoma removal surgery. Reducing operative time depends heavily on the experience of the entire robotic surgical team.

    Minimally invasive approaches to gynecologic surgery have quickly gained favor. The da Vinci surgical system robot as an option for minimally invasive surgery offers many advantages. As the placement of the system between the legs can be prohibitive, we propose a modification of the standard docking procedure by aligning the system parallel to the operating room table. Our experience is that parallel side-docking allows access to the perineum without compromising docking time and range of motion.

    The implementation of robotic technology in minimally invasive surgery has led to the need to develop more efficient and effective training methods, as well as assessment and skill maintenance tools for surgical education. Multiple simulators and procedures are available for educational and training purposes. A need for comparative evaluations of these simulators exists to aid users in selecting an appropriate device for their purposes. We conducted an objective review and comparison of the design and capabilities of all dedicated simulators of the da Vinci robot, the da Vinci Skill Simulator (DVSS) (Intuitive Surgical Inc., Sunnyvale, CA, USA), dV-Trainer (dVT) (Mimic Technologies Inc., Seattle, WA, USA), and Robotic Surgery Simulator (RoSS) (Simulated Surgical Skills, LLC, Williamsville, NY, USA). This provides base specifications of the hardware and software, with an emphasis on the training capabilities of each system. Each simulator contains a large number of training exercises, DVSS = 40, dVT = 65, and RoSS = 52 for skills development. All three offer 3D visual images but use different display technologies. The DVSS leverages the real robotic surgeon's console to provide visualization, hand controls, and foot pedals. The dVT and RoSS created simulated versions of all of these control systems. They include systems management services which allow instructors to collect, export, and analyze the scores of students using the simulators. This study is the first to provide comparative information of the three simulators functional capabilities with an emphasis on their educational skills. They offer unique advantages and capabilities in training robotic surgeons. Each device has been the subject of multiple validation experiments which have been published in the literature. But those do not provide specific details on the capabilities of the simulators which are necessary for an understanding sufficient to select the one best suited for an organization's needs.

    The role of minimally invasive surgery of gastrointestinal stromal tumours (GISTs) of the stomach remains uncertain especially for large and/or difficult located tumours. We are hereby presenting a single-centre series of robot-assisted resections using the da Vinci Surgical System (Si or Xi). Data of patients undergoing robot-assisted treatment of gastric GIST were retrieved from the prospectively collected institutional database and a retrospective analysis was performed. Patients were stratified according to size and location of the tumour. Difficult cases (DCs) were considered for size if tumour was> 50 mm and/or for location if the tumour was Type II, III or IV sec. Privette/Al-Thani classification. Between May 2010 and February 2017, 12 consecutive patients underwent robot-assisted treatment of GIST at our institution. DCs were 10/12 cases (83.3%), of which 6/10 (50%) for location, 2/10 (25%) for size and 2/10 (25%) for both. The da Vinci Si was used in 8 patients, of which 6 (75%) were DC, and the da Vinci Xi in 4, all of which (100%) were DC. In all patients, excision was by wedge resection. All lesions had microscopically negative resection margins. There was no conversion to open surgery, no tumour ruptures or spillage and no intraoperative complications. Our experience suggests a positive role of the robot da Vinci in getting gastric GIST removal with a conservative approach, regardless of size and location site. Comparative studies with a greater number of patients are necessary for a more robust assessment.

    Death and paralysis are significant risks of modern surgeries, caused by injury to blood vessels and nerves hidden by bone and other tissue. We propose an approach to surgical guidance that relies on photoacoustic (PA) imaging to determine the separation between these critical anatomical features and to assess the extent of safety zones during surgical procedures. Images were acquired as an optical fiber was swept across vessel-mimicking targets, in the absence and presence of teleoperation with a research da Vinci Surgical System. Vessel separation distances were measured directly from PA images. Vessel positions were additionally recorded based on the fiber position (calculated from the da Vinci robot kinematics) that corresponded to an observed PA signal, and these recordings were used to indirectly measure vessel separation distances. Amplitude- and coherence-based beamforming were used to estimate vessel separations, resulting in 0.52- to 0.56-mm mean absolute errors, 0.66- to 0.71-mm root-mean-square errors, and 65% to 68% more accuracy compared to fiber position measurements obtained through the da Vinci robot kinematics. Similar accuracy was achieved in the presence of up to 4.5-mm-thick ex vivo tissue. Results indicate that PA image-based measurements of the separation among anatomical landmarks could be a viable method for real-time path planning in multiple interventional PA applications.

    Nipple-sparing mastectomy (NSM) is increasingly popular for the treatment of selected breast cancers and prophylactic mastectomy. Surgical scarring and esthetic outcomes are important patient-related cosmetic considerations. Today, the concept of minimally invasive surgery has become popular, especially using robotic surgery. The authors report the first case of NSM using the latest version of the da Vinci Xi surgical system (Xi). The final incision used to remove the entire mammary gland was located behind the axillary line. In this position, hidden by the arm of the patient, the incision was not visible and was compatible with immediate breast reconstruction. © 2017 Wiley Periodicals, Inc.

    Single-incision laparoscopic surgery (SILS) is limited by the coaxial arrangement of the instruments. A surgical robot with "wristed" instruments could overcome this limitation but the "arms" collide when working coaxially. This video demonstrates a new technique of "chopstick surgery," which enables use of the robotic arms through a single incision without collision. Experiments were conducted utilizing the da Vinci S® robot (Sunnyvale, CA) in a porcine model with three laparoscopic ports (12 mm, 2-5 mm) introduced through a single "incision." Pilot work conducted while performing Fundamentals of Laparoscopic Surgery (FLS) tasks determined the optimal setup for SILS to be a triangular port arrangement with 2-cm trocar distance and remote center at the abdominal wall. Using this setup, an experienced robotic surgeon performed a cholecystectomy and nephrectomy in a porcine model utilizing the "chopstick" technique. The chopstick arrangement crosses the instruments at the abdominal wall so that the right instrument is on the left side of the target and the left instrument on the right. This arrangement prevents collision of the external robotic arms. To correct for the change in handedness, the robotic console is instructed to drive the "left" instrument with the right hand effector and the "right" instrument with the left. Both procedures were satisfactorily completed with no external collision of the robotic arms, in acceptable times and with no technical complications. This is consistent with results obtained in the box trainer where the chopstick configuration enabled significantly improved times in all tasks and decreased number of errors and eliminated instrument collisions. Chopstick surgery significantly enhances the functionality of the surgical robot when working through a small single incision. This technique will enable surgeons to utilize the robot for SILS and possibly for intraluminal or transluminal surgery.

    The increasing use of minimally invasive techniques such as robotic-assisted devices raises the question of how to acquire robotic surgery skills. The da Vinci Skills Simulator has been demonstrated to be an effective training tool in previous reports. To date, little data are available on how to acquire proficiency through simulator training. We investigated the outcome of a structured training programme for robotic surgical skills by robotic novices. This prospective study was conducted from January to December 2013 using the da Vinci Skills Simulator. Twenty participants, all robotic novices, were enrolled in a 4-week training curriculum. After a brief introduction to the simulator system, three consecutive repetitions of five selected exercises (Match Board 1, 2, 3 and Ring and Rail 1, 2) were performed in a defined order on days 1, 8, 15 and 22. On day 22, one repetition of a previously unpractised more advanced module (Needle Targeting) was also performed. After completion of each study day, the overall performance, time to completion, economy in motion, instrument collisions, excessive instrument force, instruments out of view, master workspace range and number of drops were analysed. Comparing the first and final repetition, overall score and time needed to complete all exercises, economy of motion and instrument collisions were significantly improved in nearly all exercises. Regarding the new exercise, a positive training effect could be demonstrated. While its overall entry score was significantly higher, the time to completion and economy of motion were significantly lower than the scores on the first repetition of the previous 5 exercises. It could be shown that training on the da Vinci Skills Simulator led to an improvement in technical performance of robotic novices. With regard to a new exercise, the training had a positive effect on the technical performance. © 2016 John Wiley & Sons Ltd.

    Conventional laparoscopy is the gold standard in bariatric surgery. Internationally, robot-assisted surgery is gaining in importance. Up to now there are only few reports from Germany on the use of the system in bariatric surgery. Since January 2017 we have been performing robot-assisted gastric bypass surgery. It remains unclear whether the use of the robotic system has advantages over the well-established laparoscopic technique. Within a period from January to early August 2017 a total of 53 gastric bypass operations were performed. Of these 16 proximal redo Roux-en-Y gastric bypass operations were performed with the DaVinci Si system versus 29 laparoscopic procedures. A retrospective analysis of the perioperative course was carried out. Body weight, body mass index (BMI), Edmonton obesity staging system (EOSS) and American Society of Anesthesiologists (ASA) classification did not show significant differences. There were also no significant differences in terms of estimated blood loss, intraoperative complications, duration of surgery, postoperative inflammatory parameters and weight loss. There was no mortality and no need for revisional surgery in either group. After laparoscopic surgery there was a delayed occurrence of a leak of the gastrojejunostomy followed by readmission and endoscopic negative pressure wound therapy. The results show that the proximal Roux-en-Y gastric bypass can be performed safely and efficiently using the DaVinci surgical system. Significant differences to the conventional laparoscopic procedure were not found. Larger randomized controlled trials are needed to define the role of the DaVinci system in bariatric surgery.

    To answer 2 research questions: what are the learning curve patterns of novices on the da Vinci skills simulator parameters and what parameters are appropriate for criterion-based robotic training. A total of 17 novices completed 2 simulator sessions within 3 days. Each training session consisted of a warming-up exercise, followed by 5 repetitions of the "ring and rail II" task. Expert participants (n = 3) performed a warming-up exercise and 3 repetitions of the "ring and rail II" task on 1 day. We analyzed all 9 parameters of the simulator. Significant learning occurred on 5 parameters: overall score, time to complete, instrument collision, instruments out of view, and critical errors within 1-10 repetitions (P motion and excessive instrument force only showed improvement within the first 5 repetitions. No significant learning on the parameter drops and master workspace range was found. Using the expert overall performance score (n = 3) as a criterion (overall score 90%), 9 of 17 novice participants met the criterion within 10 repetitions. Most parameters showed that basic robotic skills are learned relatively quickly using the da Vinci skills simulator, but that 10 repetitions were not sufficient for most novices to reach an expert level. Some parameters seemed inappropriate for expert-based criterion training because either no learning occurred or the novice performance was equal to expert performance. Copyright © 2013 Elsevier Inc.

    The key to successful rectal cancer resection is to perform complete total mesorectal excision (TME). Laparoscopic TME can be challenging, especially in the narrow confines of the pelvis. Robotic-assisted surgery can overcome these limitations through superior three-dimensional (3-D) visualization and the increased range of movements provided by the endowrist function. To date, all totally robotic resections of the rectum have been described using da Vinci® S or Si systems. Due to the limitations of the standard system, only hybrid procedures have been described so far. To evaluate the feasibility and short-term outcomes of performing totally robotic-assisted laparoscopic colorectal resections using the standard da Vinci® system with a fourth arm extension. The standard system was docked from the patient's left hip. Four 8-mm robotic trocars were inserted. Upon completion of phase 1 (pedicle ligation, colonic mobilization, splenic flexure takedown), the two left-sided arms are repositioned to allow phase 2 (pelvic dissection), enabling the entire procedure except for the distal transection and anastomosis to be performed robotically. Twenty-one robotic procedures were performed from August 2008 to September 2009. The mean age of the patients was 61 years (13 males). The procedures performed included seven anterior resections, seven low anterior resections, five ultralow anterior resections, one abdominoperineal resection, and one resection rectopexy. The majority of the cases were performed in patients with colon or rectal cancer. Operative time ranged from 232 to 444 (mean 316) min. Postoperative morbidity occurred in three patients (14.3%) with no mortalities or conversions. Average hospital stay was 6.4 days. Mean lymph node yield for the cases with cancer was 17.8. The standard da Vinci® system with four arms can be used to perform totally robotic-assisted colorectal procedures for the left colon and rectum with short-term outcomes similar to those of

    Virtual reality simulators with self-assessment software may assist novice robotic surgeons to augment direct proctoring in robotic surgical skill acquisition. We compare and correlate the da Vinci Trainer™ (dVT) and da Vinci Surgical Skills Simulators (dVSSS) in subjects with varying robotic experience. Students, urology residents, fellows, and practicing urologists with varying robotic experience were enrolled after local institutional review board approval. Three virtual reality tasks were preformed in sequential order (pegboard 1, pegboard 2, and tubes)-initially on the dVSSS and then on the dVT. The Mimic™ software used on both systems provides raw values and percent scores that were used in statistical evaluation. Statistical analysis was performed with the two-tailed independent t-test, analysis of variance, Tukey, and the Pearson rank correlation coefficient where appropriate. Thirty-two participants were recruited for this study and separated into five groups based on robotic surgery experience. In regards to construct validity, both simulators were able to differentiate differences among the five robotic surgery experience groups in the tubes suturing task (p≤0.00). Sixty-seven percent (4/6) robotic experts thought that surgical simulation should be implemented in residency training. The overall cohort considered both platforms easy to learn and use. Although performance scores were less in the dVT compared with the dVSSS, both simulators demonstrate good content and construct validity. The simulators appear to be equivalent for assessing surgeon proficiency and either can be used for robotic skills training with self-assessment feedback.

    Robotic rectal resection with da Vinci Si has some technical limitations, which could be overcome by the new da Vinci Xi. We compare short-term surgical and functional outcomes following robotic rectal resection with total mesorectal excision for cancer, with the da Vinci Xi (Xi-RobTME group) and the da Vinci Si (Si-RobTME group). The first consecutive 30 Xi-RobTME were compared with a Si-RobTME control group of 30 patients, selected using a one-to-one case-matched methodology from our prospectively collected Institutional database, comprising all cases performed between April 2010 and September 2016 by a single surgeon. Perioperative outcomes were compared. The impact of minimally invasive TME on autonomic function and quality of life was analyzed with specific questionnaires. The docking and overall operative time were shorter in the Xi-RobTME group (p  25 kg/m 2 was necessary in ten patients (45 vs. 0%, p < 0.001) and in six patients (37 vs. 0%, p < 0.05), in the Si-RobTME and Xi-RobTME groups, respectively. There were no differences in conversion rate, mean hospital stay, pathological data, and in functional outcomes between the two groups before and at 1 year after surgery. The technical advantages offered by the da Vinci Xi seem to be mainly associated with a shorter docking and operative time and with superior ability to perform a fully-robotic approach. Clinical and functional outcomes seem not to be improved, with the introduction of the new Xi platform.

    In Japan, as of March 2010, only 13 hospitals were using the da Vinci® system and only for selected cases. Few clinical robotic lung surgery has been done in Japan, and there are no standardized training programs, although some exist in the U.S. and are under consideration by the Japanese society for thoracic surgery. We have used the da Vinci S® Surgical System for pneumonectomy and lymph node dissection in pigs. We report and review future possibilities and problems of robotic surgery, especially concerning education, training, safety management and ethical considerations for pneumonectomy and lymph node dissection in clinical practice. The da Vinci® system consists of a surgeon's console connected to a patient-side cart, a manipulator unit with three instrument arms and a central arm to guide the endoscope. The surgeon, sitting at the console, triggers highly sensitive motion sensors that transmit the surgeon's movements to the instrument arm. We experienced exactly the same sensation as when performing standard open thoracotomy. Visual recognition is 3-D, and the high manipulation potential allows free movement of the various accessory instruments, exceeding the capacity of a surgeon's hands in video-assisted thoracic surgery (VATS) or even standard thoracotomy. Robotic surgery achieves at least the same level of operation technique for pneumonectomy and lymph node dissection under standard open thoracotomy, and it seemed as safe and easily performed as conventional VATS. The training program using pigs was effective and holds promise as a system to train thoracic surgeons in robotic lung surgery.

Uma função nervosa qualquer é assegurada pelo concurso de dois setores funcionais a que correspondem substratos anatômicos próprios; ao exercício complexo das funções da motilidade automática, por exemplo, correspondem várias estruturas anatômicas em todas as quais distinguem-se dois grupos de centros com sentido funcional diverso: um, a que cabe o papel de recepção e coordenação de estímulos, outro, de efetuação. Tal dualidade de funções primordiais é a base para o desempenho de atividades neurológicas ou psíquicas, ocorrendo tanto no setor da motilidade automática, como no da psicomotilidade, no da ação explícita, no da linguagem, no do pensamento abstrato. Foi a patologia que permitiu a Kleist a separação entre dois setores funcionais prepostos a elaboração do pensamento abstrato: aos campos 19 e 39 de Brodmann correspondem funções receptivo-coordenadoras prepostas à elaboração dos conceitos; a perturbação dessas funções conduz a uma desordem que consiste na dificuldade ou impossibilidade de elaboração dos conceitos isolados: desordem paralógia. O homem, porém, não pensa por meio de conceitos isolados; reúne-os em juízos, por meio de relações predicativas. Ê ao córtex cerebral frontal, campo 46, que dizem respeito tais funções de reunião, de efetuação do pensamento discursivo. As perturbações dessas funções, por desarranjo meramente dinâmico ou por desorganização anatômica, determinam a desordem alógica. Conquanto os dois tipos sejam encontradiços em variadas moléstias por lesão cerebral - assumindo, então, o

    Open radical retropubic prostatectomy (RRP) in obese patients (BMI ≥30) is associated with increased perioperative morbidity. The aim of the study was to evaluate the possible benefit of DaVinci robotic-assisted laparoscopic prostatectomy (RARP) compared to RRP in obese patients. We identified 255 patients with a localized prostate cancer (PCa) and BMI ≥30 treated with radical prostatectomy from January 2009 to December 2011. To adjust for risk factors of increased perioperative morbidity (nerve-sparing, pelvic lymph node dissection, prostate volume), a propensity score-based matching was performed between RRP and RARP (n=115 each group). Both groups were compared by taking into consideration histopathological outcomes as well as peri- and postoperative (30 days) morbidity. There were no differences in histopathological characteristics (pT/pN-stage, Gleason score, R-stage; all p>0.05) in both groups. Mean blood loss (276 ml vs. 937 ml), transfusion rate (0.9% vs. 8.7%) and 30-day complications according to the Clavien classification system (Clavien ≥ 2; 9.5% vs. 22.6%) were decreased in RARP (all pa multivariate logistic regression model, RARP vs. RRP was associated with a significantly reduced risk of a Clavien ≥ 2 complication during follow-up (OR 0.3; p= 0.0047). Recovery of continence was significantly better for RARP patients after 3 months (p= 0.02). There was no difference in erectile function 12 months postoperatively. Our findings of decreased transfusion and complication rates and a trend of better early recovery of continence in RARP should be considered in obese patients (BMI >30) scheduled for radical prostatectomy.

    2016-07-01

    Santello et al. [1] review an impressive amount of work on the control of biological and artificial hands that demonstrates how the concept of synergies can lead to a successful integration of robotics and neuroscience. Is it possible to generalize the same approach to the control of biological and artificial limbs and bodies beyond the hand? The human hand synergies that appear most relevant for robotic hands are those defined at the kinematic level, i.e. postural synergies [2]. Postural synergies capture the geometric relations among the many joints of the hand and allow for a low dimensional characterization and synthesis of the static hand postures involved in grasping and manipulating a large set of objects. However, many other complex motor skills such as walking, reaching, throwing, and catching require controlling multi-articular time-varying trajectories rather than static postures. Dynamic control of biological and artificial limbs and bodies, especially when geometric and inertial parameters are uncertain and the joints are compliant, poses great challenges. What kind of synergies might simplify the dynamic control of motor skills involving upper and lower limbs as well as the whole body?

    Full Text Available Foi avaliada a atividade da acetolactato sintase (ALS, em plantas resistentes e suscetíveis de B. pilosa e A. quitensis após a aplicação de herbicidas inibidores da ALS. O método baseia-se na utilização do ácido ciclopropanodicarboxílico (CPCA para inibir a cetoácido reductoisomerase (KARI, enzima que catalisa a reação seguinte do acetolactato na cadeia de biossíntese dos aminoácidos valina, leucina e isoleucina, provocando assim, o acúmulo de acetolactato, que na presença de um ácido forte forma acetoína. A base para a distinção entre os biotipos resistentes e suscetíveis é a quantidade de acetoína formada, que será maior nos biotipos em que a enzima ALS não sofreu inibição, ou seja, nos biotipos resistentes. A quantificação da acetoína acumulada ocorreu através da formação de um complexo colorido vermelho, devido a reação entre acetoína, creatina e naftol, cuja densidade ótica a 530 nm é proporcional à concentração do acetolactato formado na reação. Sendo assim, foi desenvolvido um ensaio utilizando este método após a aplicação dos herbicidas chlorimuron-ethyl e imazethapyr nos biotipos R e S de Bidens pilosa, Amaranthus quitensis no estádio de dois pares de folhas. O bioensaio demonstrou que a enzima ALS dos biotipos resistentes é insensível aos herbicidas inibidores da ALS e que este tipo de bioensaio é uma forma rápida e eficaz de diferenciação entre biotipos resistentes e suscetíveis.In order to compare the acetolactate synthase (ALS activity of resistant and susceptible biotypes of Bidens pilosa and Amaranthus quitensis to ALS inhibitor herbicides, a method based on ciclopronocarboxilic acid (CPCA to inhibit the enzyme ketoacidredutoisomerase (KARI is used.

    Robotic surgery has evolved over the last decade to compensate for limitations in human dexterity. It avoids the need for a trained assistant while decreasing error rates such as perforations. The nature of the robotic assistance varies from voice activated camera control to more elaborate telerobotic systems such as the Zeus and the Da Vinci where the surgeon controls the robotic arms using a console. Herein, we report the first series of robotic assisted colectomies in Ireland using a voice activated camera control system.

    Computerized management of medical information and 3D imaging has become the norm in everyday medical practice. Surgeons exploit these emerging technologies and bring information previously confined to the radiology rooms into the operating theatre. The paper reports the authors' experience with integrated stereoscopic 3D-rendered images in the da Vinci surgeon console. Volume-rendered images were obtained from a standard computed tomography dataset using the OsiriX DICOM workstation. A custom OsiriX plugin was created that permitted the 3D-rendered images to be displayed in the da Vinci surgeon console and to appear stereoscopic. These rendered images were displayed in the robotic console using the TilePro multi-input display. The upper part of the screen shows the real endoscopic surgical field and the bottom shows the stereoscopic 3D-rendered images. These are controlled by a 3D joystick installed on the console, and are updated in real time. Five patients underwent a robotic augmented reality-enhanced procedure. The surgeon was able to switch between the classical endoscopic view and a combined virtual view during the procedure. Subjectively, the addition of the rendered images was considered to be an undeniable help during the dissection phase. With the rapid evolution of robotics, computer-aided surgery is receiving increasing interest. This paper details the authors' experience with 3D-rendered images projected inside the surgical console. The use of this intra-operative mixed reality technology is considered very useful by the surgeon. It has been shown that the usefulness of this technique is a step toward computer-aided surgery that will progress very quickly over the next few years. Copyright © 2012 John Wiley & Sons, Ltd.

    Full Text Available Por mais que o avanço da ciência e da tecnologia esteja na raiz de vitórias decisivas na luta por melhores condições sociais, é impossível não reconhecer a ameaça crescente que o conhecimento e suas aplicações práticas representam não só para as sociedades humanas, mas para a vida em seu conjunto. A capacidade humana de intervir sobre a natureza é hoje muito maior que a possibilidade de prever com um mínimo de segurança os resultados dessa intervenção. Para Hans Jonas esse contraste só pode ser abordado com base numa exigência ética que ele sintetiza no Princípio Responsabilidade, e que se apoia na heurística do medo. Baseado numa abordagem crítica do dualismo que marca a cultura ocidental e separa matéria e espírito, corpo e mente, natureza e sociedade, Hans Jonas rejeita a ideia de que uma organização social voltada explicitamente à satisfação das necessidades humanas (e não ao lucro suprima a exigência de uma reflexão específica sobre as ameaças vindas da expansão autônoma da ciência e da tecnologia. Este trabalho, além de expor as bases do dualismo estudado por Jonas, procura mostrar que suas preocupações não são contempladas pela eventual adoção do princípio da precaução e mostra, ao final, duas áreas (biologia e geoengenharia em que a aplicação de sua filosofia da tecnologia pode ser especialmente relevante.

    Purpose of review Robot-assisted laparoscopic surgery in urology has gained immense popularity with the Da Vinci system but a lot of research teams are working on new robots. The purpose of this paper is to review current urologic robots and present future developments directions. Recent findings Future systems are expected to advance in two directions: improvements of remote manipulation robots and developments of image-guided robots. Summary The final goal of robots is to allow safer and more homogeneous outcomes with less variability of surgeon performance, as well as new tools to perform tasks based on medical transcutaneous imaging, in a less invasive way, at lower costs. It is expected that improvements for remote system could be augmented reality, haptic feed back, size reduction and development of new tools for NOTES surgery. The paradigm of image-guided robots is close to a clinical availability and the most advanced robots are presented with end-user technical assessments. It is also notable that the potential of robots lies much further ahead than the accomplishments of the daVinci system. The integration of imaging with robotics holds a substantial promise, because this can accomplish tasks otherwise impossible. Image guided robots have the potential to offer a paradigm shift.

    The term ‘robot’ tends to conjure up images of well-known metal characters like C-3P0, R2-D2, and WALL-E. The robotics research boom has in the end enabled the introduction of real robots into our homes, workspaces, and recreational places. The pop culture icons we loved have now been replaced with the likes of robot vacuums such as the Roomba and home-automated systems for smoke detectors, or WIFI-enabled thermostats, such as the Nest. Nonetheless, building a fully autonomous mobile robot is...

    Full Text Available RESUMO O câncer de mama pode ser considerado, atualmente, um problema de saúde pública devido a sua crescente incidência e índices de letalidade. Diante disso, o movimento Outubro Rosa visa chamar a atenção da população a respeito dessas neoplasia em mulheres de todo o mundo, de modo que suas ações têm por objetivo comum realizar o diagnóstico precoce no intuito de diminuir a mortalidade em decorrência dessa neoplasia. Dessa forma, o presente artigo objetiva relatar a experiência de acadêmicos do curso de Medicina da Universidade Estadual de Santa Cruz, no Módulo de Práticas de Integração Ensino, Serviço e Comunidade III (Piesc III, numa ação conjunta com a Equipe de Saúde da Família (ESF de Iguape, em Ilhéus (BA, no contexto do movimento Outubro Rosa, objetivando também compartilhar considerações sobre a formação médica levantadas pelo grupo acerca da vivência descrita. No período, realizou-se abordagem inicial na sala de espera, anamnese dirigida e foi feito o exame físico das mamas das pacientes que compareceram à Unidade de Saúde da Família. A experiência não consistiu apenas em identificar pacientes com suspeita de câncer de mama e quantificar os dados, mas numa oportunidade de exercício da Educação e Comunicação em Saúde e de desenvolvimento da relação médico-paciente. Ainda permitiu aos acadêmicos reconhecer e entender melhor as dificuldades das usuárias em relação à prevenção e promoção da saúde das mamas, sendo que se observou que diversas mulheres não estavam familiarizadas com os temas abordados. O estudante de Medicina precisa compreender que o conhecimento teórico-prático se reconstrói em cada paciente com contexto histórico específico e com diferentes visões e interpretações dos conceitos de saúde e doença. Além disso, o profissional médico deve exercitar, desde a graduação, habilidades que extrapolam o ortodoxo trabalho médico, assumindo também uma

    Full Text Available Este artigo tem por objetivo analisar a perspectiva do letramento além da alfabetização inicial, uma vez que, como prática social de leitura e escrita, entende-se que essa perspectiva deva abranger todas as etapas da educação básica e não se restringir à discussão em torno de alfabetizar versus letrar. Além de considerações sobre o letramento no panorama educacional brasileiro fundamentadas nas formulações de Soares, Kleiman e Rojo, e sobre a utilização das TICs (Tecnologias de Informação e Comunicação como ferramenta didática, o texto traz o relato de uma experiência realizada com alunos do quarto ano do ensino fundamental, em uma escola pública de Sertãozinho-SP, a partir do gênero textual ficha de cadastro que teve como resultados uma significativa aprendizagem sobre dados pessoais e de endereço. Conclui-se que projetos pautados por uma abordagem que vise atribuir função social às práticas de leitura e escrita são necessários e viáveis em todas as etapas de escolarização.

Procurou-se agrupar os principais trabalhos e revisões sobre o assunto. SÍNTESE DOS DADOS: Os ARLT são mais eficazes do que placebo e potencializam os efeitos dos corticosteróides inalados. A associação de corticosteróides inalados com agentes beta2 agonistas de longa duração (LABA é mais eficaz do que a associação de cortiscoteróides inalados + ARLT. Embora pareça racional o uso de ARLT na crise aguda de asma e rinite alérgica, mais estudos são necessários para comprovar esse benefício. Os ARLT promovem redução no tempo de hospitalização e no número de crises de sibilância em lactentes com bronquiolite viral aguda pelo vírus respiratório sincicial e na sibilância recorrente após bronquiolite viral aguda. Os ARLT são menos eficazes que os corticosteróides intranasais no manejo da rinite alérgica. Os ARLT são eficazes na asma induzida por exercício (AIE, embora não constituam a primeira linha de tratamento.

Esto, aunado a la aceptación social de esta sustancia y su fácil acceso, hacen necesario estudiar las variables asociadas a la recaída. Objetivo: Estudiar la influencia de variables sociodemográficas y psicosociales, sobre la recaída de la dependencia al alcohol. Métodos: Se realizó una investigación de campo, transversal y explicativa-correlacional, con la participación de 180 miembros de Alcohólicos Anónimos de Venezuela. Resultados: Participaron 87 mujeres y 93 hombres, con un promedio de 50 años. El índice de recaída fue de 18%, con un promedio de 130 meses de abstinencia. Se encontraron altos niveles de apoyo social, autoeficacia y autoestima, así como valores intermedios de estrés, impulsividad y resiliencia. Las variables estudiadas se asociaron con el tiempo en abstinencia (R = 0.615; p < 0.05 explicando el 35% de la varianza total. La edad (β = 0.57; p = 0.00, autoestima (β = -0.156; p = 0.02, apoyo social (β = 0.148; p = 0.02 y sexo (β = -0.135; p = 0.03 fueron las variables con mayor eficacia en la ruta principal. Conclusiones: El modelo propuesto se cumplió parcialmente. Es necesario profundizar el estudio de relaciones no planteadas entre las variables moderadoras, y si estas tienen otras que las modifiquen.

    With the initiation of laparoscopic techniques in general surgery, we have seen a significant expansion of minimally invasive techniques in the last 16 years. More recently, robotic-assisted laparoscopy has moved into the general surgeon's armamentarium to address some of the shortcomings of laparoscopic surgery. AESOP (Computer Motion, Goleta, CA) addressed the issue of visualization as a robotic camera holder. With the introduction of the ZEUS robotic surgical system (Computer Motion), the ability to remotely operate laparoscopic instruments became a reality. US Food and Drug Administration approval in July 2000 of the da Vinci robotic surgical system (Intuitive Surgical, Sunnyvale, CA) further defined the ability of a robotic-assist device to address limitations in laparoscopy. This includes a significant improvement in instrument dexterity, dampening of natural hand tremors, three-dimensional visualization, ergonomics, and camera stability. As experience with robotic technology increased and its applications to advanced laparoscopic procedures have become more understood, more procedures have been performed with robotic assistance. Numerous studies have shown equivalent or improved patient outcomes when robotic-assist devices are used. Initially, robotic-assisted laparoscopic cholecystectomy was deemed safe, and now robotics has been shown to be safe in foregut procedures, including Nissen fundoplication, Heller myotomy, gastric banding procedures, and Roux-en-Y gastric bypass. These techniques have been extrapolated to solid-organ procedures (splenectomy, adrenalectomy, and pancreatic surgery) as well as robotic-assisted laparoscopic colectomy. In this chapter, we review the evolution of robotic technology and its applications in general surgical procedures.

    Developments in robotic surgery have continued to advance care throughout the field of urology. The purpose of this review is to evaluate innovations in robotic surgery over the past 18 months. The release of the da Vinci Xi system heralded an improvement on the Si system with improved docking, the ability to further manipulate robotic arms without clashing, and an autofocus universal endoscope. Robotic simulation continues to evolve with improvements in simulation training design to include augmented reality in robotic surgical education. Robotic-assisted laparoendoscopic single-site surgery continues to evolve with improvements on technique that allow for tackling previously complex pathologic surgical anatomy including urologic oncology and reconstruction. Last, innovations of new surgical platforms with robotic systems to improve surgeon ergonomics and efficiency in ureteral and renal surgery are being applied in the clinical setting. Urologic surgery continues to be at the forefront of the revolution of robotic surgery with advancements in not only existing technology but also creation of entirely novel surgical systems.

The word "robot" is from the check word robota which means forced labor.The era of robots in surgery commenced in 1994 when the first AESOP (voice controlled camera holder prototype robot was used clinically in 1993 and then marketed as the first surgical robot ever in 1994 by the US FDA. Since then many robot prototypes like the Endoassist (Armstrong Healthcare Ltd., High Wycombe, Buck, UK, FIPS endoarm (Karlsruhe Research Center, Karlsruhe, Germany have been developed to add to the functions of the robot and try and increase its utility. Integrated Surgical Systems (now Intuitive Surgery, Inc. redesigned the SRI Green Telepresence Surgery system and created the daVinci Surgical System ® classified as a master-slave surgical system. It uses true 3-D visualization and EndoWrist ® . It was approved by FDA in July 2000 for general laparoscopic surgery, in November 2002 for mitral valve repair surgery. The da Vinci robot is currently being used in various fields such as urology, general surgery, gynecology, cardio-thoracic, pediatric and ENT surgery. It provides several advantages to conventional laparoscopy such as 3D vision, motion scaling, intuitive movements, visual immersion and tremor filtration. The advent of robotics has increased the use of minimally invasive surgery among laparoscopically naοve surgeons and expanded the repertoire of experienced surgeons to include more advanced and complex reconstructions.

    Full Text Available L'oralità risulta primaria rispetto alla scrittura sia per quanto riguarda la razza umana (filogenesi sia per quanto riguarda lo sviluppo individuale (ontogenesi, tuttavia essa ha sempre goduto di minor prestigio della scrittura. Nella prima parte di questo articolo sono ricostruiti i diversi momenti in cui questa gerarchia è stata fondata e si è affermata stabilmente: dai contrasti epocali tra Socrate e  Platone da una parte e i Sofisti dall'altra all'affermazione della centralità della scrittura da parte di Aristotele e degli aristotelici; fino, poi, all'Illuminismo, in cui l'oralità veniva ormai identificata con l'inciviltà, la rozzezza e l'arretratezza, posizione che in qualche misura permane ancora oggi. Nella seconda parte dell'articolo si ricostruisce il graduale recupero del valore dell'oralità nell'insegnamento linguistico, attraverso un'analisi dei programmi scolastici italiani, dalla Legge Casati del 1859 ai Programmi della scuola media e di quella elementare rispettivamente del 1979 e del 1985, alle più recenti "Indicazioni Moratti e infine alle "Indicazioni Fioroni". In queste ultime si sottolinea la necessità di finalizzare l'insegnamento dell'oralità anche a scopi interculturali più ampi, prioritari nella società attuale, quali il rispetto e la promozione delle differenze linguistiche e culturali, lo sviluppo del plurilinguismo; la centralità e l'autonomia dell'apprendente.   Historically, the oral tradition has been more important than writing, both in human history (philogenesis and in individual, personal history (onthogenesis, but it has always had far less prestige. The first part of this paper surveys important moments in the formation and establishment of this hierarchy, starting from the fundamental contrast between the Sophists on the one hand, and Socrates and Plato from the other, to the centrality of Aristotle and Aristotelianism, up to the Age of Enlightenment and the identification between orality

    Full Text Available Os termos publicidade e propaganda têm sofrido, em anos recentes, de um agravamento na forma indistinta com que são utilizados. Tal fato pode ser analisado dos pontos de vista lingüístico e histórico. Do ponto de vista lingüístico, é perceptível na língua inglesa a presença de três noções que precisam ser ajustadas às duas disponíveis nas línguas latinas em geral. Do ponto de vista histórico, é possível depreender, com base em uma aproximação com as idéias de Jürgen Habermas, que tanto a publicidade de “tornar públicas ações de esfera pública” quanto a de “anunciar transações comerciais” são criações burguesas comprometidas com o racionalismo e com a modernidade, sobrevindas da noção de público e, portanto, características de seu desenvolvimento socioeconômico baseado nas liberdades individuais e no mercado. Palavras-chave: Publicidade; esfera pública; mercado. ABSTRACT The terms publicidade and propaganda have increasingly been used indistinctively in Brazil in recent years. Such fact can be analyzed from linguistic and historical points of view. From the linguistic point of view, the presence of a third concept in the English language usually needs to be adjusted to the two available ones in Latin languages. From the historical point of view, it is possible to infer over a Jürgen Habermas analysis, that both meanings of publicidade – “to make public the actions within thepublic sphere” and “to advertise commercial transactions” – are bourgeois creations implied to rationalism and modernity, in-herited from the notion of “public”. Therefore, it is characteristics of its social-economic development based on individual freedoms and market orientation. Keywords: Publicity; public sphere; market.

  5. Radiation effects in a CMOS/SOS/Al-Gate D/A converter and on-chip diagnostic transistors

    Brucker, G.J.; Heagerty, W.

    1976-01-01

    This paper presents the results obtained from total dose and transient radiation tests on a CMOS/SOS/Al-Gate D/A converter and on-chip diagnostic transistors. Samples were irradiated by cobalt-60 gamma rays under worst-case conditions, and by 10-MeV electron pulses of 50-ns and 4.4-μs duration. Devices were fabricated with three different insulators; the two discussed here are standard wet oxide and a pyrogenic oxide. Test transistors on the D/A chips made it possible to diagnose the failure modes of the converter and to evaluate some special designs. These consisted of standard edge p- and n-channel transistors, edgeless units, edgeless tetrode transistors, and an edgeless type transmission gate with a diode clamp from substrate to gate. The total dose results indicate that the pyrogenic oxide increased the failure dose of the operational amplifier portion of the converter from 10 3 rads (Si) to 2 x 10 6 rads (Si); however, the sample and hold failed after exposure to a low level of 10 3 rads (Si). Test devices indicated this to be due to the radiation-induced leakage current of the transmission gate which discharges the sample and hold capacitor. The diode clamp decreased the threshold voltage shifts and the leakage currents. The edgeless devices improved the device performance because of a more abrupt turn-on. Narrow-pulse test data indicated that the edgeless units produced less photocurrent than the edge units by about a factor of three to four. Converter upset levels are less than or equal to 10 9 rads/s due to precision requirements which make a few millivolt transients untenable

    Robots have the potential to display a higher degree of lifetime morphological adaptation than natural organisms. By adopting a modular approach, robots with different capabilities, shapes, and sizes could, in theory, construct and reconfigure themselves as required. However, current modular robots have only been able to display a limited range of hardwired behaviors because they rely solely on distributed control. Here, we present robots whose bodies and control systems can merge to form entirely new robots that retain full sensorimotor control. Our control paradigm enables robots to exhibit properties that go beyond those of any existing machine or of any biological organism: the robots we present can merge to form larger bodies with a single centralized controller, split into separate bodies with independent controllers, and self-heal by removing or replacing malfunctioning body parts. This work takes us closer to robots that can autonomously change their size, form and function.Robots that can self-assemble into different morphologies are desired to perform tasks that require different physical capabilities. Mathews et al. design robots whose bodies and control systems can merge and split to form new robots that retain full sensorimotor control and act as a single entity.

  9. Feasibility Study of Low Force Robotic Friction Stir Process and its Effect On Cavitation Erosion and Electrochemical Corrosion for Ni Al Bronze Alloys

    Robotic friction stir processing (FSP) has not been widely researched to date. This is perhaps due to the limited force capabilities of industrial robots in comparison with dedicated commercial FSP equipment. When operating a FSP machine, the force used to plunge the tools may range from 5000 to 8000 N which is currently beyond the capability of most robots. However, the capacity of robotic manipulators is increasing, so low force friction stir processing is becoming feasible. The ability of the robot arm to apply a controlled force that is normal to a 3-dimensional surface without the need to reorient the workpiece makes it a very useful tool for FSP of complex components. In this analysis, a robot arm with a capacity of 2500 N is used to improve the surface properties of nickel aluminum bronze (NAB) using low force FSP. Multiple passes were applied to the surface of the test sample for a more consistent spread of the stir zone. The sample was then microhardness tested and demonstrated a 62 pct increase in surface hardness. Cavitation erosion testing of the original and processed surfaces was also performed as per ASTM G-32. The erosion rate of the processed NAB sample was 44 pct of the rate experienced by the original cast NAB sample. Finally, the corrosion potentials of FSP NAB were measured at 45 mV less anodic than the unprocessed material, indicating that the processed material is more noble relative to the cast NAB sample.

    Full Text Available Este artigo parte do conceito de saúde como o conjunto de condições integrais e coletivas de existência, influenciado pelo contexto político, sócio-econômico, cultural e ambiental. Desse modo, mostra que os estudos sobre as desigualdades, disparidades ou iniqüidades em saúde devem ir muito além da comparação de dados estatísticos, uma vez que o racismo nem sempre se apresenta de forma explícita e mensurável nas interações sociais. É preciso analisar as diversas experiências vivenciadas por negros e não-negros numa dada condição social, considerando sexo, idade, região de moradia, educação, origem familiar, ocupação, renda, orientação sexual, filiação religiosa, suas capacidades e incapacidades, sua rede social e suas possibilidades de acesso aos serviços e bens sociais. Por fim, o artigo enumera diretrizes que possam colaborar com o grande desafio de formulação de políticas públicas que combatam e erradiquem as imensas desigualdades entre brancos e negros.

    Starting from the classical concepts introduced by Sherrington [1] and considerably elaborated by Bernstein [2], much has been learned about motor synergies in the last several years. The contributions of the group funded by the European project ;The Hand Embodied; are remarkable in the field of biological and robotic control of the hand based on synergies, and they are reflected in this enjoyable review [3]. There, Santello et al. adopt Bernstein's definition of motor synergies as multiple elements working together towards a common goal, with the result that multiple degrees of freedom are controlled within a lower-dimensional space than the available number of dimensions.

    2014-01-01

    Surgical robotic systems have been available for almost twenty years. The first surgical robotic systems were designed as supportive systems for laparoscopic approaches in general surgery (the first procedure was a cholecystectomy in 1987). The da Vinci Robotic System is the most common system used for robotic surgery today. This system is widely used in urology, gynecology and other surgical disciplines, and recently there have been initial reports of its use in spine surgery, for transoral access and anterior approaches for lumbar inter-body fusion interventions. SpineAssist, which is widely used in spine surgery, and Renaissance Robotic Systems, which are considered the next generation of robotic systems, are now FDA approved. These robotic systems are designed for use as guidance systems in spine instrumentation, cement augmentations and biopsies. The aim is to increase surgical accuracy while reducing the intra-operative exposure to harmful radiation to the patient and operating team personnel during the intervention. We offer a review of the published literature related to the use of robotic systems in spine surgery and provide information on using robotic systems.

    Introduction: There is a growing interest in achieving higher survival rates with the lowest morbidity in localized prostate cancer (PC) treatment. Consequently, minimally invasive techniques such as low-dose rate brachytherapy (BT) and robotic-assisted prostatectomy (RALP) have been developed and improved. Comparative analysis of functional outcomes and quality of life in a prospective series of 51BT and 42Da Vinci prostatectomies DV. Materials and Methods: Comparative analysis of functional outcomes and quality of life in a prospective series of 93 patients with low-risk localized PC diagnosed in 2011. 51 patients underwent low-dose rate BT and the other 42 patients RALP. IIEF to assess erectile function, ICIQ to evaluate continence and SF36 test to quality of life wee employed. Results: ICIQ at the first revision shows significant differences which favour the BT group, 79% present with continence or mild incontinence, whereas in the DV group 45% show these positive results. Differences disappear after 6 months, with 45 patients (89%) presenting with continence or mild incontinence in the BT group vs. 30 (71%) in the DV group. 65% of patients are potent in the first revision following BT and 39% following DV. Such differences are not significant and cannot be observed after 6 months. No significant differences were found in the comparative analysis of quality of life. Conclusions: ICIQ after surgery shows significant differences in favour of BT, which disappear after 6 months. Both procedures have a serious impact on erectile function, being even greater in the DV group. Differences between groups disappear after 6 months. (author)

MÉTODOS: Estudo qualitativo com dez mães ouvintes com filhos surdos que frequentavam atendimento especializado em Centro de Estudos e Pesquisas em Reabilitação, no estado de São Paulo, há pelo menos dois anos. Realizou-se entrevista semiestruturada com as mães e foi feita análise da fala das participantes, buscando compreender o sentido que as mães deram à sua comunicação. RESULTADOS: Apesar do diagnóstico de seis crianças ter sido feito antes de um ano de idade e, considerando-se os múltiplos sentimentos das mães frente à surdez de seus filhos, observou-se que, em alguns casos, o diagnóstico poderia ter ocorrido antes se a fala das mães fosse valorizada. Percebeu-se dificuldade de "escuta" dos profissionais da saúde em relação às dúvidas, queixas e questionamentos das mães. Constatou-se que, em alguns casos, mesmo quando ocorreu a triagem auditiva neonatal ou o diagnóstico oportuno, retardou-se o atendimento à criança porque não foram feitos encaminhamentos adequados para locais que trabalham na área da surdez. No momento do diagnóstico, a forma como foi comunicada a surdez à família necessitaria levar em consideração as condições sociais, culturais e emocionais das mães. CONCLUSÕES: Ressalta-se a importância da qualificação e atenção dos profissionais de saúde, para possibilitar o diagnóstico precoce, o apoio aos pais e o encaminhamento e seguimento adequados para os casos de surdez.OBJETIVO: Investigar la vivencia de las madres entre la sospecha, el diagnóstico de sordera y el encaminamiento para habilitación, así como la percepción de ellas respecto a la forma como se dio y explicó el diagnóstico.

    Robots are simultaneously real machines and technical images that challenge our sense of self. In the Open Forum I discuss the movie Ex Machina by director Alex Garland. The robot Ava, played by Alicia Vikander, is a rare portrait of what could be interpreted as a feminist robot (and...... there are spoilers ahead for any readers unfamiliar with this movie). Though she apparently is created as the dream of the ‘perfect woman’, sexy and beautiful, she also develops and urges to free herself from the slavery of her creator, Nathan Bateman. She is a robot created along the perfect dimensions...... as a Vitruvian robot but is also a creature which could be interpreted as a human being. However, the point I want to raise is not whether Ava’s reaction to robot slavery is justified or not but how her portrait raises questions about the blurred lines between reality and fiction when we discuss our robotic...

    Robotics education courses are rapidly spreading throughout the nation's colleges and universities. Engineering schools are offering robotics courses as part of their mechanical or manufacturing engineering degree program. Two year colleges are developing an Associate Degree in robotics. In addition to regular courses, colleges are offering seminars in robotics and related fields. These seminars draw excellent participation at costs running up to $200 per day for each participant. The last one drew 275 people from Texas to Virginia. Seminars are also offered by trade associations, private consulting firms, and robot vendors. IBM, for example, has the Robotic Assembly Institute in Boca Raton and charges about $1,000 per week for course. This is basically for owners of IBM robots. Education (and training) can be as short as one day or as long as two years. Here is the educational pattern that is developing now

El algoritmo emplea un procedimiento estocástico RANSAC cuya eficiencia ha sido mejorada. El muestreo aleatorio ha sido sustituido por un muestreo guiado sobre las cadenas de contorno de la imagen, que son ordenadas de acuerdo a un criterio de probabilidad de formar parte de la elipse buscada. Esta estrategia disminuye notablemente la cantidad de muestras necesarias, permitiendo que el algoritmo sea adecuado para tiempo real. Abstract: In this paper, we present a ellipse detection algorithm developed to measure the 3-D position of a circular feature in a robotic application. The algorithm uses a RANSAC stochastic procedure whose efficiency has been significantly improved, substituting the random sampling with a guided sampling on the curve segments in the image. The contours of the image are first split analyzing their curvature. Then the curve segments are sorted according to their likelihood to be part of the ellipse. We have used the length as a prior indicator of this likelihood. The RANSAC algorithm starts considering only the longer curve segments whilst shorter curve segments are progressively incorporated. This strategy notably diminishes the amount of samples needed and makes the algorithm suitable for real time.

  15. Learning in robotic manipulation: The role of dimensionality reduction in policy search methods. Comment on "Hand synergies: Integration of robotics and neuroscience for understanding the control of biological and artificial hands" by Marco Santello et al.

    Ficuciello, Fanny; Siciliano, Bruno

    2016-07-01

    A question that often arises, among researchers working on artificial hands and robotic manipulation, concerns the real meaning of synergies. Namely, are they a realistic representation of the central nervous system control of manipulation activities at different levels and of the sensory-motor manipulation apparatus of the human being, or do they constitute just a theoretical framework exploiting analytical methods to simplify the representation of grasping and manipulation activities? Apparently, this is not a simple question to answer and, in this regard, many minds from the field of neuroscience and robotics are addressing the issue [1]. The interest of robotics is definitely oriented towards the adoption of synergies to tackle the control problem of devices with high number of degrees of freedom (DoFs) which are required to achieve motor and learning skills comparable to those of humans. The synergy concept is useful for innovative underactuated design of anthropomorphic hands [2], while the resulting dimensionality reduction simplifies the control of biomedical devices such as myoelectric hand prostheses [3]. Synergies might also be useful in conjunction with the learning process [4]. This aspect is less explored since few works on synergy-based learning have been realized in robotics. In learning new tasks through trial-and-error, physical interaction is important. On the other hand, advanced mechanical designs such as tendon-driven actuation, underactuated compliant mechanisms and hyper-redundant/continuum robots might exhibit enhanced capabilities of adapting to changing environments and learning from exploration. In particular, high DoFs and compliance increase the complexity of modelling and control of these devices. An analytical approach to manipulation planning requires a precise model of the object, an accurate description of the task, and an evaluation of the object affordance, which all make the process rather time consuming. The integration of

    Full Text Available O zumbido, definido como percepção consciente de um som originado nas orelhas ou no sistema nervoso do paciente, representa até os dias atuais um grande desafio no que concerne seu tratamento, baseia-se na estimulação com agulhas de pontos específicos definidos sobre a anatomia humana. A utilização da Acupuntura (ACP em sintomas como o zumbido assemelha-se ao modelo aplicado nos quadros álgicos, já que ambos estão relacionados como experiência sensorial e emocional subjetiva e desagradável. OBJETIVO: Estudar a eficácia da acupuntura no alívio sintomático de forma aguda no zumbido. FORMA DE ESTUDO: Clínico prospectivo. MATERIAL E MÉTODO: Foi realizado um estudo prospectivo, randomizado e duplo-cego em 76 pacientes atendidos no Ambulatório de Zumbido do Departamento de Otorrinolaringologia e Cirurgia de Cabeça e Pescoço da UNIFESP-EPM no período compreendido entre abril e junho de 2005. Todos os pacientes tinham queixa de zumbido e foram submetidos a anamnese clínica, exame físico e exames subsidiários a fim de se investigar sua etiologia. Os pacientes eram então encaminhados a um primeiro pesquisador que determinou um valor numérico subjetivo inicial do zumbido através de Escala Visual Analógica (EVA, variando de 0 a 10 pontos. Após isto, foram encaminhados para outra sala na qual um médico acupunturista, que não tinha acesso à avaliação inicial, separou os pacientes em Grupo Controle e Grupo Estudo de acordo com a ordem de atendimento, de maneira alternada. O ponto de ACP utilizado nos pacientes do Grupo Estudo situa-se a 6,5cm acima do ápice do pavilhão auditivo na região têmporo-parietal. O ponto utilizado no Grupo Controle situa-se 3cm acima do ponto anterior, na mesma linha vertical. Foram então encaminhados à sala inicial para uma nova avaliação pelo primeiro pesquisador, onde foram orientados a redefinir o escore subjetivo do zumbido. RESULTADOS: Dos 76 pacientes estudados, 29 eram do sexo

    This description of "soft robotics" is not intended to be a conventional review, in the sense of a comprehensive technical summary of a developing field. Rather, its objective is to describe soft robotics as a new field-one that offers opportunities to chemists and materials scientists who like to make "things" and to work with macroscopic objects that move and exert force. It will give one (personal) view of what soft actuators and robots are, and how this class of soft devices fits into the more highly developed field of conventional "hard" robotics. It will also suggest how and why soft robotics is more than simply a minor technical "tweak" on hard robotics and propose a unique role for chemistry, and materials science, in this field. Soft robotics is, at its core, intellectually and technologically different from hard robotics, both because it has different objectives and uses and because it relies on the properties of materials to assume many of the roles played by sensors, actuators, and controllers in hard robotics. © 2018 Wiley-VCH Verlag GmbH & Co.

    Full Text Available The continuous use of ALS-inhibiting herbicides has led to the evolution of herbicide-resistant weeds worldwide. Greater beggarticks is one of the most troublesome weeds found in the soybean production system in Brazil. Recently, a greater beggarticks biotype that is resistant (R to ALS inhibitors due to Trp574Leu mutation in the ALS gene was identified. Also, the adaptive traits between susceptible (S and R to ALS inhibitors biotypes of greater beggarticks were compared. Specifically, we aimed to: (1 evaluate and compare the relative growth rates (RGR between the biotypes; (2 analyze the seed germination characteristics of R and S biotypes under different temperature conditions; and (3 evaluate their competitive ability in a replacement series study. The experiments were conducted at the University of Arkansas, USA, in 2007 and at Universidade Federal do Rio Grande do Sul (Federal University of Rio Grande do Sul, Brazil, in 2008. Plant proportions for replacement series studies were respectively 100:0, 75:25, 50:50, 25:75 and 0:100, with a total population of 150 plants m-2. There was no difference in RGR between R and S biotypes. The R-biotype germination rate was lower than that of the S biotype. However, at low temperature conditions (15 ºC, the reverse was observed. In general, there is no difference in the competitive ability between R and S greater beggarticks biotypes.O uso contínuo de herbicidas inibidores da ALS tem levado à evolução de plantas daninhas resistentes mundialmente.

    Full Text Available DWI é uma técnica totalmente não invasiva que tem sido utilizada com sucesso por muitos anos em imagens do cérebro e recentemente incluída como parte da avaliação de outros sistemas, por exemplo, no abdome e pelve e na cabeça e pescoço. Apesar de a DWI e a medida dos valores de ADC serem capazes de fornecer informações de tipos histológicos específicos de tumores, a maioria dos centros de imagem ainda não os adotaram como parte da rotina na avaliação da cabeça e pescoço. A medida de ADC demonstrou ser útil para discriminar tipos específicos de tumores histológicos, especialmente para diferenciar lesões benignas sólidas de massas malignas, importante na avaliação de linfonodos cervicais, principalmente para diferenciar processos nodais benignos de malignos, para diferenciar as alterações pós-radioterapia de tumor residual e ter uso potencial para predizer sucesso terapêutico. Além disso, DWI/ADC parece ser um método mais seguro e mais acessível, considerando a ausência de radiação ionizante e ao maior custo do FDG-PET na localização de tumores e diferenciar massas benignas de malignas. Com todas essas vantagens e potencialidades, DWI/ADC certamente fará parte da rotina na avaliação por imagem da cabeça e pescoço.

    2009-08-01

    Full Text Available Exchangeable Al has been used as a criterion for the calculation of lime requirement in several Brazilian States. However, the laboratory method with extraction by a 1 mol L-1 KCl solution followed by indirect alkaline titration is not accurate for some Brazilian soils, mainly in the case of soils with high organic matter content. The objective of this study was therefore to evaluate the stoichiometry of H+/Al3+ in KCl soil extracts. The results suggested that organically complexed Al is the main contributor to exchangeable acidity in soils enriched with organic matter. Liming recommendations for organic soils based exclusively on exchangeable Al determined by the NaOH titration method should therefore be revised.A determinação de alumínio trocável é utilizada como critério para cálculo de calagem em vários estados brasileiros. Contudo, a determinação indireta pela titulação com NaOH, após extração com solução de KCl 1 mol L-1, pode não ser adequada para certos tipos de solos brasileiros, notadamente aqueles que apresentem altos teores de carbono orgânico. Dessa forma, o principal objetivo deste trabalho foi avaliar a estequiometria da relação H+/Al3+ em extratos de KCl. Os resultados obtidos sugerem que o Al complexado pela matéria orgânica, em solos orgânicos, é o principal contribuinte para a acidez trocável obtida por titulação. Dessa forma, a recomendação de calagem em solos orgânicos baseado somente na determinação de alumínio trocável por titulação com NaOH deve ser revista.

    Swarm robotics is one of the fastest growing areas of modern technology. Being subclass of multi-agent systems it inherits the main part of scientific-methodological apparatus of construction and functioning of practically useful complexes, which consist of rather autonomous independent agents. Ambient light sensors (ALS) are widely used in robotics. But speaking about swarm robotics, the technology which has great number of specific features and is developing, we can't help mentioning that its important to use sensors on each robot not only in order to help it to get directionally oriented, but also to follow light emitted by robot-chief or to help to find the goal easier.

    Agricultural robotics has received attention for approximately 20 years, but today there are only a few examples of the application of robots in agricultural practice. The lack of uptake may be (at least partly) because in many cases there is either no compelling economic benefit......, or there is a benefit but it is not recognized. The aim of this chapter is to quantify the economic benefits from the application of agricultural robots under a specific condition where such a benefit is assumed to exist, namely the case of early seeding and re-seeding in sugar beet. With some predefined assumptions...... with regard to speed, capacity and seed mapping, we found that among these two technical systems both early seeding with a small robot and re-seeding using a robot for a smaller part of the field appear to be financially viable solutions in sugar beet production....

    Martin Marietta Aero and Naval Systems has advanced the CAD art to a very high level at its Robotics Laboratory. One of the company's major projects is construction of a huge Field Material Handling Robot for the Army's Human Engineering Lab. Design of FMR, intended to move heavy and dangerous material such as ammunition, was a triumph in CAD Engineering. Separate computer problems modeled the robot's kinematics and dynamics, yielding such parameters as the strength of materials required for each component, the length of the arms, their degree of freedom and power of hydraulic system needed. The Robotics Lab went a step further and added data enabling computer simulation and animation of the robot's total operational capability under various loading and unloading conditions. NASA computer program (IAC), integrated Analysis Capability Engineering Database was used. Program contains a series of modules that can stand alone or be integrated with data from sensors or software tools.

    Almost all industrial robots use internal sensors such as shaft encoders which measure rotary position, or tachometers which measure velocity, to control their motions. Most controllers also provide interface capabilities so that signals from conveyors, machine tools, and the robot itself may be used to accomplish a task. However, advanced external sensors, such as visual sensors, can provide a much greater degree of adaptability for robot control as well as add automatic inspection capabilities to the industrial robot. Visual and other sensors are now being used in fundamental operations such as material processing with immediate inspection, material handling with adaption, arc welding, and complex assembly tasks. A new industry of robot vision has emerged. The application of these systems is an area of great potential

    2009-09-06

    Surgical robotics is one of the most dynamically advancing areas of biomedical engineering. In the past few decades, computer-integrated interventional medicine has gained significance internationally in the field of surgical procedures. More recently, mechatronic devices have been used for nephrectomy, cholecystectomy, as well as in orthopedics and radiosurgery. Estimates show that 70% of the radical prostatectomies were performed with the da Vinci robot in the United States last year. Robot-aided procedures offer remarkable advantages in neurosurgery both for the patient and the surgeon, making microsurgery and Minimally Invasive Surgery a reality, and even complete teleoperation accessible. This paper introduces surgical robotic systems developed primarily for brain and spine applications, besides, it focuses on the different research strategies applied to provide smarter, better and more advanced tools to surgeons. A new system is discussed in details that we have developed together with the Johns Hopkins University in Baltimore. This cooperatively-controlled system can assist with skull base drilling to improve the safety and quality of neurosurgery while reducing the operating time. The paper presents the entire system, the preliminary results of phantom and cadaver tests and our efforts to improve the accuracy of the components. An effective optical tracking based patient motion compensation method has been implemented and tested. The results verify the effectiveness of the system and allow for further research.

    2016-01-01

    Robotic surgery is the most dynamic development in the sector of minimally invasive operations currently. It should not be viewed as an alternative to laparoscopy, but as the next step in a process of technological evolution. The advancement of robotic surgery, in terms of the introduction of the Da Vinci Xi, permits the variable use of optical devices in all four trocars. Due to the new geometry of the "patient cart," an operation can be performed in all spatial directions without re-docking. Longer instruments and the markedly narrower mechanical elements of the "patient cart" provide greater flexibility as well as access similar to those of traditional laparoscopy. Currently, robotic surgery is used for a variety of indications in the treatment of benign gynecological diseases as well as malignant ones. Interdisciplinary cooperation and cooperation over large geographical distances have been rendered possible by telemedicine, and will ensure comprehensive patient care in the future by highly specialized surgery teams. In addition, the second operation console and the operation simulator constitute a new dimension in advanced surgical training. The disadvantages of robotic surgery remain the high costs of acquisition and maintenance as well as the laborious training of medical personnel before they are confident with using the technology.

    Full Text Available Tenta-se ressaltar como o caminho trilhado por Freud na concepção dos conceitos de saúde e doença se diferencia do modo dicotômico como em geral a separação entre esses conceitos é pensada pela saúde mental. Trava-se uma discussão acerca de algumas construções freudianas fundamentais: o estudo da sexualidade sem perspectiva normalizadora; o uso de diagnósticos que ultrapassam a bipartição entre saudável e doente; e uma proposta de tratamento que não visa apenas a eliminação da doença. Freud inaugura com isso uma nova lógica, nomeada aqui como um "entre caminhos".This article emphasizes how the path followed by Freud in the elaboration of the concepts of health and illness differs from the dichotomist manner in which they are generally thought of in the area of Mental Health. There is a discussion on some of the fundamental Freudian constructions: the study of the sexuality without a perspective of normalization; the use of diagnosis that overwhelm the bipartition regarding the healthy and the sick; and a treatment proposal that does not simply aim at the elimination of the illness. Freud inaugurates, therefore, a new logic, named in this paper as a "between paths".

    Full Text Available Resumo Os óxidos de alumínio (Al2O3 nanoestruturados vêm recebendo apreciável atenção nos últimos anos em diversas áreas. Em especial, a α-Al2O3 que é uma fase estável, se destaca por sua estabilidade térmica e química em diversas aplicações. Entre as técnicas de síntese da α-Al2O3, o processo de combustão assistida por micro-ondas tem recebido notável importância por se tratar de um método rápido, com facilidade de processamento e baixo custo, que possibilita a obtenção de pós cerâmicos com boas características estruturais. Apesar da sua simplicidade em termos de processamento, vários parâmetros podem influenciar nas propriedades finais dos pós cerâmicos. Neste sentido, o objetivo deste estudo foi avaliar a influência da razão combustível/oxidante (Rco e da potência do micro-ondas (Pmic na quantidade de α-Al2O3 formada, no tamanho de cristalito e na cristalinidade dos pós formados. Para isso, foram utilizados três Rco (1:1, 2,5:1 e 5:1 e três Pmic (450, 675 e 900 W para realizar as reações de combustão. Os materiais obtidos foram calcinados a 900 ºC por 2 h para verificar a influência dos parâmetros na formação da α-Al2O3. Para avaliar melhor a influência dos parâmetros da síntese foi utilizado o planejamento fatorial 2² com quatro pontos centrais. As técnicas de difração de raios X e de microscopia eletrônica por varredura foram utilizadas para investigar a estrutura cristalina e a morfologia dos pós formados. Os resultados mostraram que tamanhos de cristalitos de 10 a 13 nm foram obtidos utilizando mistura pobre em combustível (Rco de 1:1, independente da potência utilizada. A influência dos parâmetros de síntese também foi observada na morfologia, onde espécies de carbonatos de alumínio foram observadas após a reação de combustão quando o experimento foi realizado usando mistura rica em combustível.

  7. The debate over robotics in benign gynecology.

    Science.gov (United States)

    Rardin, Charles R

    2014-05-01

    The debate over the role of the da Vinci surgical robotic platform in benign gynecology is raging with increasing fervor and, as product liability issues arise, greater financial stakes. Although the best currently available science suggests that, in the hands of experts, robotics offers little in surgical advantage over laparoscopy, at increased expense, the observed decrease in laparotomy for hysterectomy is almost certainly, at least in part, attributable to the availability of the robot. In this author's opinion, the issue is not whether the robot has any role but rather to define the role in an institutional environment that also supports the safe use of vaginal and laparoscopic approaches in an integrated minimally invasive surgery program. Programs engaging robotic surgery should have a clear and self-determined regulatory process and should resist pressures in place that may preferentially support robotics over other forms of minimally invasive surgery.

    In the present work, the Ti-Nb-2%Al alloys, with the rate varied Nb from 15 to 40%, they were submitted to the quenched since 1000 deg C, in water, to verify the influence of Nb in the structure and phase composition. The alloys were obtained in a process of five coalitions in an oven to electric arch and, soon afterwards, wrought the hot and homogenized to 1200 deg C, for 10 hours. After the quenching and conventional metallographic preparation of the samples obliquely cut, the alloys were examined through the optic microscopic, diffraction of ray-X and Vickers hardness. The very defined correlation was shown between the niobium rate and the structure resulting from the quenched alloys. The phase martensitic was revealed in the alloy with 15% Nb, the phases martensitic and beta metastable in the alloys containing above 30% Nb and the phase beta in the alloys with 38% Nb and 40% Nb. the hardness of the phase martensitic increases with the increment of the niobium rate.

    Control of the human hand has been both difficult to understand scientifically and difficult to emulate technologically. The article by Santello and colleagues in the current issue of Physics of Life Reviews[1] highlights the accelerating pace of interaction between the neuroscience of controlling body movement and the engineering of robotic hands that can be used either autonomously or as part of a motor neuroprosthesis, an artificial body part that moves under control from a human subject's own nervous system. Motor neuroprostheses typically involve a brain-computer interface (BCI) that takes signals from the subject's nervous system or muscles, interprets those signals through a decoding algorithm, and then applies the resulting output to control the artificial device.

    Full Text Available Silicon nitride is a covalent ceramic material of high corrosion resistance and mechanical stability at elevated temperatures. Due to these properties, its use in metallurgical processes, such as the casting of alloys, is increasing. Therefore, the characterization of the interface between Si3N4 and the casted metal is of great importance to investigate possible interactions, which might deteriorate the ceramic mould or contaminate the metal. In this work, the use of Si3N4 as crucible material for Al-casting has been studied, by investigating the corrosion attack of liquid Al at a temperature of 1150 ºC during 30 days in air. The interface was characterized by X-ray diffraction, scanning electron microscopy and energy dispersive spectroscopy. It has been found that due to superficial oxidation two oxide layers form - SiO2 on Si3N4 and Al2O3 on Al - which effectively hinder further reactions under the conditions studied, confering high corrosion resistance to the Si3N4 crucible.Nitreto de silício (Si3N4 é um material cerâmico covalente de elevada resistência à corrosão e estabilidade mecânica em temperaturas elevadas. Devido a essas propriedades, sua utilização em processos metalúrgicos, tais como em fundição de ligas metálicas, é crescente. Desta forma, a caracterização da interface entre Si3N4 e metais fundidos é de grande interesse para investigar possíveis interações as quais poderão deteriorar o material cerâmico e/ou contaminar o metal. Nesse trabalho o uso de Si3N4 como material base de cadinhos para fundição de alumínio foi estudado, pela investigação do ataque corrosivo de Al líquido a 1150 ºC durante 30 dias, ao ar. A interface foi caracterizada por difração de raios X, microscopia eletrônica de varredura e espectroscopia de energia dispersiva. É encontrado que devido à oxidação superficial dois óxidos se formam - SiO2 no Si3N4 e Al2O3 no Al - os quais evitam possíveis reações sob as condi

    2016-04-01

    Full Text Available The idea of robotic telesurgery dates back to the 1970s when the National Aeronautics and Space Administration (NASA developed a project to utilize remotely controlled robots to perform surgeries on astronauts. The history of robotic surgery begins in 1985, when Kwoh et al used a robot - Puma 200, for performing neurosurgical biopsies with greater precision. This was soon followed by the introduction of PROBOT in 1988, a robotic system for ultrasound guided prostatic resection. A major breakthrough in the field of robotic surgery came with the performance of the first transatlantic telesurgical procedure (Operation Lindbergh by a surgeon in the United States operating on a patient in France. Laparoscopic cholecystectomy was performed on a 68-year-old lady in Strasbourg, France by Professor Marescaux utilising a Zeus robotic system located in New York, USA. There were no complications during the procedure and the patient was discharged 2 days later. Since then, telesurgery has been carried out in multiple locations around the globe with successful outcomes.

  17. Para além da paz liberal? respostas ao "retrocesso" Beyond liberal peace? responses to "backsliding"

    Directory of Open Access Journals (Sweden)

    Oliver P Richmond

    2010-12-01

    Full Text Available A ortodoxia familiar de construção da paz liberal depende da transplantação e da exportação de condicionalidade e dependência, com vistas a consolidar um contrato social entre populações, seus governos e o Estado, em que repouse uma paz liberal legítima e consensual. O que, com frequência, ocorre, é uma forma híbrida de paz liberal, sujeita a críticas locais poderosas, à resistência, por vezes, e à percepção de que a construção da paz internacional está fracassando em corresponder às expectativas. Em termos kantianos, os problemas com que a paz liberal tem se deparado e a crise pela qual está hoje passando podem ser denominados "retrocesso". Tem sido particularmente notável que a construção da paz liberal não vem sendo capaz de construir políticas unidas a partir de fragmentos territoriais no Kosovo, na Bósnia, no Afeganistão, no Iraque, no Sri Lanka e mesmo na Irlanda do Norte, onde alguns ou todos de seus elementos estão em desenvolvimento. Isso indica uma necessidade ou de reforma do modelo liberal para a paz, ou de estabelecimento de uma capacidade de coexistência desse modelo com alternativas, ou de substituição do modelo. Este artigo examina uma gama de questões inerentes ao paradigma de construção da paz liberal, algumas causas de "retrocesso" e o que pode ser feito no que tange a tais causas, no sentido de utilizar a construção da paz para criar um novo contrato social e atingir o que se poderia muito bem ser uma forma "híbrida liberal-local" de paz.The familiar orthodoxy of liberal peacebuilding depends upon transplanting and exporting conditionality and dependency in order to cement a social contract between populations, their governments and the state, on which rests a legitimate and consensual liberal peace.

    Thiel, David D; Winfield, Howard N

    2008-04-01

    The modern-day urologist is continually armed with new instruments and technology aimed at decreasing the overall invasiveness of urologic procedures. Robotic technology is aimed at improving clinical outcomes by correcting human technical inadequacies such as hand tremors and imprecise suturing. The first reported use of robotics to assist with surgery was in 1985, and the first use of robotics in urology was published in 1989. The currently utilized master-slave system (da Vinci Robotic Platform), Intuitive Surgical, Sunnyvale, CA) has popularized robotic surgery for use in numerous urologic conditions including prostate cancer, bladder cancer, renal cancer, uretero-pelvic junction obstruction, and pelvic prolapse. New developments in robotic technology may revolutionize many other aspects of urology including percutaneous renal access and rounding on patients after surgery. This review provides a brief overview of the history of robotics in urology, a description of the da Vinci surgical system and its current utilization as well as limitations, and a review of evolving robotic technology in the field of urology.

    We started robot-assisted thoracoscopic esophagectomy using the da Vinci surgical system from June 2010 and operated on 30 cases by December 2013. Herein, we examined the usefulness of robot-assisted thoracoscopic esophagectomy and compared it with conventional esophagectomy by right thoracotomy. Patients requiring an invasion depth of up to the muscularis propria with preoperative diagnosis were considered for surgical adaptation, excluding bulky lymph node metastasis or salvage surgery cases. The outcomes of 30 patients who underwent robot-assisted surgery (robot group) and 30 patients who underwent conventional esophagectomy by right thoracotomy (thoracotomy group) up to December 2013 were retrospectively examined. Five ports were used in the robot-assisted thoracoscopic esophagectomy: 3rd intercostal (da Vinci right arm), 6th intercostal (da Vinci camera), 9th intercostal (da Vinci left arm), 4th and 8th intercostals (for assistance). There was no significant difference in patient characteristics. Robot group/right thoracotomy group: Operation time, 563/398 min; thoracic procedure bleeding volume, 21/135 ml; number of thoracic lymph node radical dissections, 25/23. Postoperative complications were recurrent nerve paralysis, 16.7/16.7%; pneumonia, 6.7%/10.0%; anastomotic leakage, 10.0/20.0%; surgical site infection, 0/10.0%; hospitalization, 17/30 days. For the robot group, the operation time was significantly longer, but the amount of intraoperative bleeding and postoperative hospitalization were significantly reduced. Robot-assisted thoracoscopic esophagectomy enables delicate surgical procedures owing to the 3D effect of the field of view and articulated forceps of the da Vinci. This procedure reduces bleeding and postoperative hospitalization and is less invasive than conventional esophagectomy by right thoracotomy.

    Robotic-assisted surgery offers a solution to fundamental limitations of conventional laparoscopic surgery, and its use is gaining wide popularity. However, the application of this technology has yet to be established in hepatic surgery. A retrospective analysis of our prospectively collected liver surgery database was performed. Over a 6-month period, all consecutive patients who underwent robotic-assisted hepatic resection for a liver neoplasm were included. Demographics, operative time, and morbidity encountered were evaluated. A total of 7 robotic-assisted liver resections were performed, including 2 robotic-assisted single-port access liver resections with the da Vinci-Si Surgical System (Intuitive Surgical Sunnyvalle, Calif.) USA. The mean age was 44.6 years (range, 21-68 years); there were 5 male and 2 female patients. The mean operative time (± SD) was 61.4 ± 26.7 minutes; the mean operative console time (± SD) was 38.2 ± 23 minutes. No conversions were required. The mean blood loss was 100.7 mL (range, 10-200 mL). The mean hospital stay (± SD) was 2 ± 0.4 days. No postoperative morbidity related to the procedure or death was encountered. Our initial experience with robotic liver resection confirms that this technique is both feasible and safe. Robotic-assisted technology appears to improve the precision and ergonomics of single-access surgery while preserving the known benefits of laparoscopic surgery, including cosmesis, minimal morbidity, and faster recovery.

    The introduction of robot-assisted surgery, and specifically the da Vinci Surgical System, is one of the biggest breakthroughs in surgery since the introduction of anaesthesia, and represents the most significant advancement in minimally invasive surgery of this decade. One of the first surgical uses of the robot was in orthopaedics, neurosurgery, and cardiac surgery. However, it was the use in urology, and particularly in prostate surgery, that led to its widespread popularity. Robotic surgery, is also widely used in other surgical specialties including general surgery, gynaecology, and head and neck surgery. In this article, we reviewed the current applications of robot-assisted surgery in different surgical specialties with an emphasis on urology. Clinical results as compared with traditional open and/or laparoscopic surgery and a glimpse into the future development of robotics were also discussed. A short introduction of the emerging areas of robotic surgery were also briefly reviewed. Despite the increasing popularity of robotic surgery, except in robot-assisted radical prostatectomy, there is no unequivocal evidence to show its superiority over traditional laparoscopic surgery in other surgical procedures. Further trials are eagerly awaited to ascertain the long-term results and potential benefits of robotic surgery.

    Information and communication technology (ICT) and mechatronics play a basic role in medical robotics and computer-aided therapy. In the last three decades, in fact, ICT technology has strongly entered the health-care field, bringing in new techniques to support therapy and rehabilitation. In this frame, medical robotics is an expansion of the service and professional robotics as well as other technologies, as surgical navigation has been introduced especially in minimally invasive surgery. Localization systems also provide treatments in radiotherapy and radiosurgery with high precision. Virtual or augmented reality plays a role for both surgical training and planning and for safe rehabilitation in the first stage of the recovery from neurological diseases. Also, in the chronic phase of motor diseases, robotics helps with special assistive devices and prostheses. Although, in the past, the actual need and advantage of navigation, localization, and robotics in surgery and therapy has been in doubt, today, the availability of better hardware (e.g., microrobots) and more sophisticated algorithms(e.g., machine learning and other cognitive approaches)has largely increased the field of applications of these technologies,making it more likely that, in the near future, their presence will be dramatically increased, taking advantage of the generational change of the end users and the increasing request of quality in health-care delivery and management.

    This chapter focuses on rehabilitation robotics which can be used to augment the clinician's toolbox in order to deliver meaningful restorative therapy for an aging population, as well as on advances in orthotics to augment an individual's functional abilities beyond neurorestoration potential. The interest in rehabilitation robotics and orthotics is increasing steadily with marked growth in the last 10 years. This growth is understandable in view of the increased demand for caregivers and rehabilitation services escalating apace with the graying of the population. We provide an overview on improving function in people with a weak limb due to a neurological disorder who cannot properly control it to interact with the environment (orthotics); we then focus on tools to assist the clinician in promoting rehabilitation of an individual so that s/he can interact with the environment unassisted (rehabilitation robotics). We present a few clinical results occurring immediately poststroke as well as during the chronic phase that demonstrate superior gains for the upper extremity when employing rehabilitation robotics instead of usual care. These include the landmark VA-ROBOTICS multisite, randomized clinical study which demonstrates clinical gains for chronic stroke that go beyond usual care at no additional cost.

Visa, portanto, compreender a subjetividade procurando esclarecer a sua emergência à luz de uma perspectiva ontológica e estética, para além da Psicologia.Taking as a start point the concept of repetition - as it's been developed by Gilles Deleuze's philosophy - the article treats the habit notion and, in particular, a critique to the way psychology deals with such notion. In addition, presents how the habit's constitution is inseparable from a passive contemplation, which is responsible for the foundation of the alive time, still showing how possible it is to think about the subjectivity emergence in terms of a new inflection. Therefore, based on an ontology and esthetic perspective, it goals an understanding of subjectivity, as well as its emergence beyond psychology.

    Engineers and interns at this NASA field center are building the prototype of a robotic rover that could go where no wheeled rover has gone before-into the dark cold craters at the lunar poles and across the Moon s rugged highlands-like a walking tetrahedron. With NASA pushing to meet President Bush's new exploration objectives, the robots taking shape here today could be on the Moon in a decade. In the longer term, the concept could lead to shape-shifting robot swarms designed to explore distant planetary surfaces in advance of humans. "If you look at all of NASA s projections of the future, anyone s projections of the space program, they re all rigid-body architecture," says Steven Curtis, principal investigator on the effort. "This is not rigid-body. The whole key here is flexibility and reconfigurability with a capital R."

    The last two decades have seen a remarkable shift in the neuro-rehabilitation paradigm. Neuroscientists and clinicians moved away from the perception that the brain is static and hardwired, to a new dynamic understanding that plasticity is a fundamental property of the adult human brain and might be harnessed to remap or create new neural pathways. Capitalizing on this innovative understanding, we introduced a paradigm shift in the clinical practice in 1989 when we initiated the development of the MIT-Manus robot for neuro-rehabilitation and deployed it in the clinic in 1994 10. Since then, we and others have developed and tested a multitude of robotic devices for stroke, spinal cord injury, cerebral palsy, multiple sclerosis, and Parkinson’s disease. Here we discuss whether robotic therapy has achieved a level of maturity to justify its broad adoption in the clinical realm as a tool for motor recovery. PMID:23080044

    Resection of retroperitoneal tumors is usually perfomed using the anterior retroperitoneal approach. Our report presents an innovative method utilizing a robotic surgical system. A 50-yr-old male patient visited our hospital due to a known paravertebral mass. Magnetic resonance imaging showed a well-encapsulated mass slightly abutting the abdominal aorta and left psoas muscle at the L4-L5 level. The tumor seemed to be originated from the prevertebral sympathetic plexus or lumbosacral trunk and contained traversing vessels around the tumor capsule. A full-time robotic transperitoneal tumor resection was performed. Three trocars were used for the robotic camera and working arms. The da Vinci Surgical System® provided delicate dissection in the small space and the tumor was completely removed without damage to the surrounding organs and great vessels. This case demonstrates the feasibility of robotic resection in retroperitoneal space. Robotic surgery offered less invasiveness in contrast to conventional open surgery. PMID:21218046

    Full Text Available In this paper, we have investigated the concept of “Cultural Robotics” with regard to the evolution of social into cultural robots in the 21st Century. By defining the concept of culture, the potential development of a culture between humans and robots is explored. Based on the cultural values of the robotics developers, and the learning ability of current robots, cultural attributes in this regard are in the process of being formed, which would define the new concept of cultural robotics. According to the importance of the embodiment of robots in the sense of presence, the influence of robots in communication culture is anticipated. The sustainability of robotics culture based on diversity for cultural communities for various acceptance modalities is explored in order to anticipate the creation of different attributes of culture between robots and humans in the future.

    This paper describes Robot Vision and Operation System for Nuclear Advanced Robot. This Robot Vision consists of robot position detection, obstacle detection and object recognition. With these vision techniques, a mobile robot can make a path and move autonomously along the planned path. The authors implemented the above robot vision system on the 'Advanced Robot for Nuclear Power Plant' and tested in an environment mocked up as nuclear power plant facilities. Since the operation system for this robot consists of operator's console and a large stereo monitor, this system can be easily operated by one person. Experimental tests were made using the Advanced Robot (nuclear robot). Results indicate that the proposed operation system is very useful, and can be operate by only person. (author)

Este trabalho teve por objetivo desenvolver uma metodologia prática de detecção de biótipos resistentes de Bidens spp. aos herbicidas do grupo dos inibidores da ALS, através de testes germinativos em solução herbicida. O trabalho foi dividido em três fases de experimentos independentes. A primeira fase constituiu-se da elaboração de curvas do tipo dose-resposta para um biótipo suscetível de Bidens spp. quando germinado em soluções de quatro herbicidas pré-emergentes (flumetsulan, diclosulan, imazaquin e metribuzin. O objetivo desta fase foi conhecer quais herbicidas se adaptam melhor à metodologia, utilizando as seguintes doses: 2C, 1C, 1/2C, 1/4C, 1/8C, 1/16C, 1/32C, 1/64C e água (em que C = dose comercial. A segunda fase constituiu-se da elaboração de curvas do tipo dose-resposta para os herbicidas selecionados na primeira fase (imazaquin e metribuzin utilizando-se um biótipo resistente, com a intenção de identificar a dose que proporciona a maior amplitude de resposta entre os diferentes biótipos. A terceira fase constituiu-se da instalação de um teste comparativo, simultâneo, entre três biótipos resistentes e um biótipo suscetível, quando expostos à germinação nas soluções dos herbicidas selecionados na primeira fase, utilizando-se das doses escolhidas na segunda fase. Os biótipos resistentes de Bidens spp. apresentaram maior capacidade de desenvolver radículas em solução herbicida de imazaquin a 87,5 mg L-1 quando comparados com os biótipos suscetíveis, fato que comprova a aplicabilidade do método.

    Full Text Available Recentemente, vozes do meio castrense brasileiro voltaram a insistir que as terras indígenas na Amazônia representam uma ameaça à soberania nacional. Nesse tipo de manifestação, que é em realidade um ataque retórico aos direitos indígenas estabelecidos sob o lastro de uma longa tradição indigenista, as críticas militares pretenderam, em nome da "segurança nacional", desqualificar a totalidade dessa política de Estado. Este artigo observa não apenas o anacronismo de tais críticas ante a tradição indigenista brasileira e sua filiação a uma tradição autoritária mais recente, mas também como os elementos discursivos desta última confrontam-se agora com novos debates sobre a regulação social, ante a noção de diferença e significado que, com relação a ela, podem ser postulados os direitos coletivos.Some Brazilian military voices have recently turned to condemn indigenous lands in Amazonia as a threat to national sovereignty. Under this manifestation (actually, a rhetorical attack to indigenous rights established by a large indigenist tradition, military criticism try to discredit the State indigenist politics as a whole. This article appreciates both the anachronism of these critics regarding the large Brazilian indigenist legal tradition and their affiliation with a more recent authoritarian tradition; but it also observes how discursive elements of this last one (the authoritarian tradition face the new debate about social regulation, regarding the notion of difference and the meaning of collective rights concerned to it.

    Purpose: To report experience and early results of laparoscopic implantation for interstitial brachytherapy (BT) of solitary bladder tumors and the feasibility of a high-dose-rate (HDR) schedule. Methods and Materials: From December 2009 to April 2015, 57 patients with a T2 solitary bladder tumor were treated in Arnhem with transurethral bladder resection followed by external beam irradiation, applied to the bladder and regional iliac lymph nodes, 40 Gy in 20 fractions, 5 fractions per week, and within 1 week interstitial HDR BT, in selected cases combined with partial cystectomy and lymph node dissection. The BT catheters were placed via a transabdominal approach with robotic assistance from a Da Vinci robot after a successful initial experience with a nonrobotic laparoscopic approach. The fraction schedule for HDR was 10 fractions of 2.5 Gy, 3 fractions per day. This was calculated to be equivalent to a reference low-dose-rate schedule of 30 Gy in 60 hours. Data for oncologic outcomes and toxicity (Common Toxicity Criteria version 4) were prospectively collected. Results: These modifications resulted in an average postoperative hospitalization of 6 days, minimal blood loss, and no wound healing problems. Two patients had severe acute toxicity: 1 pulmonary embolism grade 4 and 1 cardiac death. Late toxicity was mild (n=2 urogenital grade 3 toxicity). The median follow-up was 2 years. Using cumulative incidence competing risk analysis, the 2-year overall, disease-free, and disease-specific survival and local control rates were 59%, 71%, 87%, and 82%, respectively. Conclusions: The benefits of minimally invasive surgery for implantation of BT catheters and the feasibility of HDR BT in bladder cancer are documented. The patient outcome and adverse events are comparable to the best results published for a bladder-sparing approach.

    Abstract. The citrus industry in Brazil plays a role of great economic, social, generating jobs, income and development. Brazil is the largest producer of citrus, the State of Sergipe stands out in 5th place in national production. Among the many pest problems faced by Brazilian citrus is Citrus Variegated Chlorosis (CVC, known as the yellowing caused by the bacterium Xylella fastidiosa Wells et al. The CVC was officially identified in Brazil in 1987, in orchards of “Triângulo Mineiro” and North and northwest of the state of São Paulo. In the Northeast Region of Brazil, was found in 1996 in the municipality of Boquim Sergipe, and Bahia in 1997, the municipalities of Rio Real and Itapicuru. The aim was to review the literature on the species of leafhoppers vectors of CVC, and verify that occur in the state of Sergipe. The first symptoms are seen in the leaves, then go for the fruits and end up affecting the entire plant, and to be perceived can take between five months and two years. The main vectors of X. fastidiosa in citrus are the sharpshooters of the family Cicadellidae. In Brazil 12 sharpshooters species have already been confirmed. For the state of Sergipe, is scarce information about the Cicadellidae vectors, the data are limited to the northern coast of Bahia, except for vague quote about four genus (Oncometropia, Acrogonia, Dilobopterus and Homolodisca and three species (Homolodisca ignorata Melichar, Acrogonia sp. and Homolodisca spottii Takiya, Cavichioli & McKamey.

    To report the feasibility of bulky pelvic lymph node resection with robotic-assisted single-port laparoscopy in a patient with cervical cancer before chemoradiation therapy. Resection of pelvic bulky lymph nodes with a narrated video of da Vinci single-port platform surgery (Intuitive Surgical, Sunnyvale, CA) (Canadian Task Force classification III). Although not enough evidence exists to reveal that single-site surgery is better than traditional endoscopic surgery, several studies have suggested that single-site robotic surgery has certain advantages such as less postoperative analgesic use, shorter hospital stay, and quicker recovery. Furthermore, robotic single-site surgery has evolved single-site procedures. Compared with the single-port laparoendoscopic procedure, the robotic-assisted single-port laparoscopic procedure offers some advantages to minimally invasive surgery such as greater dexterity, 3-dimensional visualization, and fewer instrument clashes. These advantages make robotic single-port surgery more preferable; nevertheless, the lack of articulating instruments and the low quality of optical exposure are still challenges. Robotic single-port pelvic lymphadenectomy was first described by Tateo et al [1] in an endometrial carcinoma patient. We present a robotic single-port pelvic bulky lymph node resection in an advanced cervical cancer patient. Even though current data are controversial about removing bulky lymph nodes in patients with advanced cervical cancer, some studies have recommended that debulking of tumor-involved lymph nodes before chemoradiation may be benefical for these patients (Leblanc et al [2], Marnitz et al [3]). In our case, the patient underwent robotic-assisted single-port laparoscopy using the da Vinci Single-Site platform. The abdominal cavity was insufflated from a 3-cm umblical incision, and a 5-lumen single port was inserted. Then, an 8.5-mm 3-dimensional camera was inserted through the port, and for dissection and

    Datteri, Edoardo

    2013-03-01

    This article addresses prospective and retrospective responsibility issues connected with medical robotics. It will be suggested that extant conceptual and legal frameworks are sufficient to address and properly settle most retrospective responsibility problems arising in connection with injuries caused by robot behaviours (which will be exemplified here by reference to harms occurred in surgical interventions supported by the Da Vinci robot, reported in the scientific literature and in the press). In addition, it will be pointed out that many prospective responsibility issues connected with medical robotics are nothing but well-known robotics engineering problems in disguise, which are routinely addressed by roboticists as part of their research and development activities: for this reason they do not raise particularly novel ethical issues. In contrast with this, it will be pointed out that novel and challenging prospective responsibility issues may emerge in connection with harmful events caused by normal robot behaviours. This point will be illustrated here in connection with the rehabilitation robot Lokomat.

    This thesis studies aspects of self-sufficient energy (energy autonomy) for truly autonomous robots and towards sociable robots. Over sixty years of history of robotics through three developmental ages containing single robot, multi-robot systems, and social (sociable) robots, the main objective...... of roboticists mostly focuses on how to make a robotic system function autonomously and further, socially. However, such approaches mostly emphasize behavioural autonomy, rather than energy autonomy which is the key factor for not only any living machine, but for life on the earth. Consequently, self......-sufficient energy is one of the challenges for not only single robot or multi-robot systems, but also social and sociable robots.

  11. Beyond synergies. Comment on "Hand synergies: Integration of robotics and neuroscience for understanding the control of biological and artificial hands" by Marco Santello et al.

    2016-07-01

    The target paper by Santello et al. [1] uses the observation that hand shape during grasping can be described by a small set of basic postures, or ;synergies,; to describe the possible neural basis of motor control during this complex behavior. In the literature, the term ;synergy; has been used with a number of different meanings and is still loosely defined, making it difficult to derive concrete analogs of corresponding neural structure. Here, I will define ;synergy; broadly, as a set of parameters bound together by a pattern of correlation. With this definition, it can be argued that behavioral synergies are just one facet of the correlational structuring used by the brain to generate behavior. As pointed out in the target article, the structure found in synergies is driven by the physical constraints of our bodies and our surroundings, combined with the behavioral control imparted by our nervous system. This control itself is based on correlational structure which is likely to be a fundamental property of brain function.

    Full Text Available We discuss the capabilities of continuum (continuous backbone robot structures in the performance of under-actuated grasping. Continuum robots offer the potential of robust grasps over a wide variety of object classes, due to their ability to adapt their shape to interact with the environment via non-local continuum contact conditions. Furthermore, this capability can be achieved with simple, low degree of freedom hardware. However, there are practical issues which currently limit the application of continuum robots to grasping. We discuss these issues and illustrate via an experimental continuum grasping case study.

    Krebs, Herman Igo; Hogan, Neville

    2012-11-01

    The last two decades have seen a remarkable shift in the neurorehabilitation paradigm. Neuroscientists and clinicians moved away from the perception that the brain is static and hardwired to a new dynamic understanding that plasticity is a fundamental property of the adult human brain and might be harnessed to remap or create new neural pathways. Capitalizing on this innovative understanding, the authors introduced a paradigm shift in the clinical practice in 1989 when they initiated the development of the Massachusetts Institute of Technology-Manus robot for neurorehabilitation and deployed it in the clinic in 1994 (Krebs et al. 1998). Since then, the authors and others have developed and tested a multitude of robotic devices for stroke, spinal cord injury, cerebral palsy, multiple sclerosis, and Parkinson disease. Here, the authors discuss whether robotic therapy has achieved a level of maturity to justify its broad adoption in the clinical realm as a tool for motor recovery.

    2014-01-01

    This paper discusses a new class of robots known as concentric tube robots and their application to transnasal skull base surgery. The endonasal approach has clear benefits for patients, but the surgery presents challenges that strongly motivate the use of robotic tools. In this paper, the concentric tube robot concept is described, and preliminary experimental results for transnasal skull base surgery are reviewed. Just as the da Vinci robot has revolutionized many laparoscopic surgeries, we expect concentric tube robots will enable the advancement of skull base surgery and the development of other minimally invasive procedures that require access through constrained paths.

    This paper summarizes the research results on the friendly network robotics in fiscal 1996. This research assumes an android robot as an ultimate robot and the future robot system utilizing computer network technology. The robot aiming at human daily work activities in factories or under extreme environments is required to work under usual human work environments. The human robot with similar size, shape and functions to human being is desirable. Such robot having a head with two eyes, two ears and mouth can hold a conversation with human being, can walk with two legs by autonomous adaptive control, and has a behavior intelligence. Remote operation of such robot is also possible through high-speed computer network. As a key technology to use this robot under coexistence with human being, establishment of human coexistent robotics was studied. As network based robotics, use of robots connected with computer networks was also studied. In addition, the R-cube (R{sup 3}) plan (realtime remote control robot technology) was proposed. 82 refs., 86 figs., 12 tabs.

    Full Text Available Zircônia tetragonal estabilizada com ítria foi mecanicamente metalizada com titânio e a condição de molhamento avaliada com as ligas convencionais Ag-28Cu e Au-18Ni. Estas dissolveram o revestimento de titânio para uma completa distribuição deste metal ativo na superfície cerâmica, gerando uma liga ativa in situ e possibilitando adequadas ligações químicas ao metal base na temperatura de união. Os melhores resultados de molhamento foram selecionados para brasagem indireta em forno de alto-vácuo nas juntas ZrO2/Ti-6Al-4V. Testes de detecção de vazamento de gás hélio foram realizados na interface de união das juntas; amostras removidas na seção transversal de juntas estanques foram examinadas por técnicas de análise microestrutural. Formou-se uma camada escura adjacente à cerâmica metalizada, responsável pelo molhamento ocasionado pela liga Ag-28Cu. Entretanto, o uso da liga Au-18Ni resultou em precipitação de intermetálicos e microtrincamento interfacial. Perfis de microdureza através da interface resultante até onde a zircônia mostrou típico escurecimento não indicaram alternância significativa entre medições consecutivas; os resultados dos ensaios de resistência mecânica à flexão-3p foram considerados satisfatórios.Yttria tetragonal zirconia polycrystal was mechanically metallized with titanium and the wetting behavior on the ceramic surface was analyzed using the conventional fillers Ag-28Cu and Au-18Ni.

    The value of robotics in general surgery may be for advanced minimally invasive procedures. Unlike other specialties, formal fellowship training opportunities for robotic general surgery are few. As a result, most surgeons currently develop robotic skills in practice. Our goal was to determine whether robotic cholecystectomy is a safe and effective bridge to advanced robotics in general surgery. Before performing advanced robotic procedures, 2 surgeons completed the Intuitive Surgical da Vinci training course and agreed to work together on all procedures. Clinical surgery began with da Vinci cholecystectomy with a plan to begin advanced procedures after at least 10 cholecystectomies. We performed a retrospective review of our pilot series of robotic cholecystectomies and compared them with contemporaneous laparoscopic controls. The primary outcome was safety, and the secondary outcome was learning curve. There were 16 procedures in the robotics arm and 20 in the laparoscopic arm. Two complications (da Vinci port-site hernia, transient elevation of liver enzymes) occurred in the robotic arm, whereas only 1 laparoscopic patient (slow to awaken from anesthetic) experienced a complication. None was significant. The mean time required to perform robotic cholecystectomy was significantly longer than laparoscopic surgery (91 v. 41 min, p < 0.001). The mean time to clear the operating room was significantly longer for robotic procedures (14 v. 11 min, p = 0.015). We observed a trend showing longer mean anesthesia time for robotic procedures (23 v. 15 min). Regarding learning curve, the mean operative time needed for the first 3 robotic procedures was longer than for the last 3 (101 v. 80 min); however, this difference was not significant. Since this experience, the team has confidently gone on to perform robotic biliary, pancreatic, gastresophageal, intestinal and colorectal operations. Robotic cholecystectomy can be performed reliably; however, owing to the significant

This epidemiological study focused on the evaluation of health services based on the observation of the assistance delivered by the Single Health System in 12 maternities and 134 delivers. The Brazilian Health Ministry or World Health Organization standards were adopted for comparison. The results revealed problems related to the structure of some maternities, where some well-proven practices in normal childbirth are still little used, whereas other prejudicial or ineffective ones are routinely used. Reversing this picture is essential in order to offer humanized quality care to women with consequent reductions in maternal and neonatal mortality rates, in such a way that the region achieves the millennium goals established for improving human development.Con la finalidad de subsidiar a gestores responsables por la atención a la salud de la mujer en la formulación de políticas públicas dirigidas al desarrollo humano, se propone la presente investigación, cuyo objetivo es evaluar la estructura y proceso de atención al parto y al neonato desarrollada en una región del interior del Estado de São Paulo, Brasil.

Faço uma análise dessa documentação buscando reconstruir parte do cotidiano dos presos, pressupondo a existência de uma ordem paralela, com igual ou maior força do que a oficial, mas que não anulava a arbitrariedade e a violência desta última. Entretanto, essa ordem paralela podia ser rompida, a qualquer momento, seja por confrontos diretos entre os próprios presos ou entre os presos e os funcionários da prisão. Dentre os tipos de protesto, a escrita foi um dos mais utilizados pelos presos e, dependendo da estratégia sugerida nas cartas, era possível conquistar espaços sem romper com a ordem prisional. O recurso à escrita foi utilizado por presos, letrados ou não, de diferentes condições jurídicas - escravos, libertos e livres -, independentemente do tipo de pena que estivessem cumprindo.The aim of this article is to discuss the prison community in Bahia during the 19th century, using the correspondence written by prisoners. I analyze this documentation in an attempt to reconstruct the daily life of the prisoners, presupposing the existence of a parallel order equal to or more powerful than the official prison order, but that did not end the arbitrariness and the violence of the latter. This parallel order could be broken any moment, whether because of direct confrontation among the prisoners themselves, or due to confrontation between prisoners and prison staff. Among different types of protest, writing was widely used by prisoners and, depending on the strategy suggested in the letters, it was possible to obtain gains without breaking the prison order. Written appeals were used by prisoners, educated or not, of different legal conditions, slaves, freed and free, independent of the type of sentence they were serving.

    Over the past decade, the introduction of robotics in the field of medicine has provided a new approach to patients requiring surgery, and both its advantages and disadvantages are currently under study by many groups worldwide. The use of robotics has especially been considered by the urological community as a treatment option in radical prostatectomy. The current case report is one in which the da Vinci Surgical System, with fourth arm use was employed in radical prostatectomy. This case presents a unique occurrence in which a bolt of the Prograsper forcep became loose during an operation, leading to diminished device functionality and later impedance of its removal. A circumstance such as this has not previously been reported, so we introduce for other robotic surgeons our unique instrumental malfunction case during a robotic prostatectomy.

    One of the most significant limitations of surgical robots has been their inability to allow multiple surgeons and surgeons-in-training to engage in collaborative control of robotic surgical instruments. We report the initial experience with a novel two-headed da Vinci surgical robot that has two collaborative modes: the "swap" mode allows two surgeons to simultaneously operate and actively swap control of the robot's four arms, and the "nudge" mode allows them to share control of two of the robot's arms. The utility of the mentoring console operating in its two collaborative modes was evaluated through a combination of dry laboratory exercises and animal laboratory surgery. The results from surgeon-resident collaborative performance of complex three-handed surgical tasks were compared to results from single-surgeon and single-resident performance. Statistical significance was determined using Student's t-test. Collaborative surgeon-resident swap control reduced the time to completion of complex three-handed surgical tasks by 25% compared to single-surgeon operation of a four-armed da Vinci (P collaboration during robotic surgery and improves the performance of complex surgical tasks. The mentoring console has the potential to improve resident participation in surgical robotics cases, enhance resident education in surgical training programs engaged in surgical robotics, and improve patient safety during robotic surgery.

    The aim of this study was to evaluate the clinical outcome after robotically assisted myxoma surgery performed at our institution. Altogether nine patients underwent robotically assisted atrial myxoma excision. A control group was selected from 18 consecutive patients who underwent an isolated atrial myxoma excision via conventional sternotomy. Preoperative patient characteristics were similar between the two study groups. Postoperative health-related quality of life (HRQoL) was also evaluated. All robotic operations were completed successfully using the da Vinci™ telesurgical system. There was no mortality in either of the two study groups. Procedure, cardiopulmonary bypass, aortic occlusion, and ventilation times were shorter in the sternotomy group when compared to the robotic group. Length of stay was statistically significantly shorter in the robotically assisted group. Postoperative quality of life did not differ between the two study groups. We conclude that robotically assisted surgery is a feasible method for treating atrial myxomas.

Sin embargo, la información sobre los efectos del daño inducido en servicio (daño extrínseco en la integridad estructural de estos materiales esescasa. En este contexto, en este trabajo se evalúa la influencia del daño extrínseco en la resistencia mecánica residual de dos calidades con microestructuras diferentes. Para ello, se emplea la técnica de indentación esférica como medio para generar daño de forma controlada. Los resultados muestran que al incrementar el tamaño de grano del carburo y el contenido de cobalto, la respuesta mecánica de carburos cementados frente al contacto esférico es cada vez más cuasi-plástica, bajo la aplicación de cargas tanto monotónicas como cíclicas, y en consecuencia el material muestra una mayor tolerancia al daño.Palabras claves: carburos cementados, indentación esférica, resistencia mecánica residual, tolerancia al daño._______________________________________________________________________________AbstractThe mechanical behavior of WC-Co cemented carbides has been studied in detail taking into account the pre-existing material (intrinsic damage defects.

    The project I am working on at NASA-Johnson Space Center in Houston, TX is a hexapod robot. This project was started by various engineers at the Trick Lab. The goal of this project is to have the hexapod track a yellow ball or possibly another object from left to right and up/down. The purpose is to have it track an object like a real creature. The project will consist of using software and hardware. This project started with a hexapod robot which uses a senor bar to track a yellow ball but with a limited field of vision. The sensor bar acts as the robots "head." Two servos will be added to the hexapod to create flexion and extension of the head. The neck and head servos will have to be programmed to be added to the original memory map of the existing servos. I will be using preexisting code. The main programming language that will be used to add to the preexisting code is C++. The trick modeling and simulation software will also be used in the process to improve its tracking and movement. This project will use a trial and error approach, basically seeing what works and what does not. The first step is to initially understand how the hexapod works. To get a general understanding of how the hexapod maneuvers and plan on how to had a neck and head servo which works with the rest of the body. The second step would be configuring the head and neck servos with the leg servos. During this step, limits will be programmed specifically for the each servo. By doing this, the servo is limited to how far it can rotate both clockwise and counterclockwise and this is to prevent hardware damage. The hexapod will have two modes in which it works in. The first mode will be if the sensor bar does not detect an object. If the object it is programmed to look for is not in its view it will automatically scan from left to right 3 times then up and down once. The second mode will be if the sensor bar does detect the object. In this mode the hexapod will track the object from left to

    The need for automated welding repair systems of marine structures, ship hulls and nuclear installations had lead to an increasing demand for subsea robots. Considering the application of friction welding to perform underwater repairs, a TRICEPT TR600 robot has been identified as the most suitable system to withstand the high reaction forces characteristic of this process. This study reviews initially the research and development work carried out at GKSS to modify and test a Siemens-MANUTEC robot. After a description of the TRICEPT TR600 robot a marinization concept is presented and discussed in detail. Problems of galvanic corrosion in seawater are addressed in a separate chapter. The deflection of the robot in subsea water currents is estimated with a worst-case calculation. (orig.)

Para tal, fazemos uma breve comparação da "normatividade da vida" com o conceito contemporâneo de auto-organização de Michel Debrun, argumentando que a emergência da norma vital se situa num estágio secundário de um processo de (auto-organização da vida e, portanto, tal normatividade não teria a conotação vitalista, erroneamente atribuída a Canguilhem.We discuss the epistemology of the sciences of life and health elaborated by Georges Canguilhem.

We make a brief comparison of his concept of "normativity of life" with the contemporary concept of "self-organization" proposed by Michel Debrun, arguing that the emergency of the vital norm occurs on the second stage of the process of life self-organization and therefore such normativity does not have the vitalist connotation erroneously attributed to Canguilhem.

    The compositions Ni20Al80, Ni25Al75, Ni40Al60, Ni50Al50, Ni60Al40 and Ni75Al25 (at. %) were heated in a calibrated thermal analysis equipment. All runs were conducted at a heating rate of 10 deg C/min under a dynamic argon atmosphere. Each composition was heated until the completion of the corresponding exothermic reaction responsible for intermetallic compound formation, and, also heated to 1480 deg C. The products obtained were characterized using X ray diffraction in order to identify the intermetallic compounds that were synthesized. Moreover, the results were evaluated using variance analysis. As a result, enthalpies of formation of Ni{sub 2}Al{sub 3} and Ni{sub 3}Al compounds were determined by means of this methodology. Experimental values were 167 kJ/mol and 93 kJ/mol for Ni{sub 2}Al{sub 3} and Ni{sub 3}Al, respectively. The former is 18% lower than the value found on literature, while the latter is 6% greater.

    Robotic surgical platforms have seen increased use among minimally invasive gastrointestinal surgeons (von Fraunhofer et al. in J Biomed Mater Res 19(5):595-600, 1985. doi: 10.1002/jbm.820190511 ). However, these systems still suffer from lack of haptic feedback, which results in exertion of excessive force, often leading to suture failures (Barbash et al. in Ann Surg 259(1):1-6, 2014. doi: 10.1097/SLA.0b013e3182a5c8b8 ). This work catalogs tensile strength and failure load among commonly used sutures in an effort to prevent robotic surgical consoles from exceeding identified thresholds. Trials were thus conducted on common sutures varying in material type, gauge size, rate of pulling force, and method of applied force. Polydioxanone, Silk, Vicryl, and Prolene, gauges 5-0 to 1-0, were pulled till failure using a commercial mechanical testing system. 2-0 and 3-0 sutures were further tested for the effect of pull rate on failure load at rates of 50, 200, and 400 mm/min. 3-0 sutures were also pulled till failure using a da Vinci robotic surgical system in unlooped, looped, and at the needle body arrangements. Generally, Vicryl and PDS sutures had the highest mechanical strength (47-179 kN/cm 2 ), while Silk had the lowest (40-106 kN/cm 2 ). Larger diameter sutures withstand higher total force, but finer gauges consistently show higher force per unit area. The difference between material types becomes increasingly significant as the diameters decrease. Comparisons of identical suture materials and gauges show 27-50% improvement in the tensile strength over data obtained in 1985 (Ballantyne in Surg Endosc Other Interv Tech 16(10):1389-1402, 2002. doi: 10.1007/s00464-001-8283-7 ). No significant differences were observed when sutures were pulled at different rates. Reduction in suture strength appeared to be strongly affected by the technique used to manipulate the suture. Availability of suture tensile strength and failure load data will help define software safety

    Full Text Available This problem was to calculate the path a robot would take to navigate an obstacle field and get to its goal. Three obstacles were given as negative potential fields which the robot avoided, and a goal was given a positive potential field that attracted the robot. The robot decided each step based on its distance, angle, and influence from every object. After each step, the robot recalculated and determined its next step until it reached its goal. The robot's calculations and steps were simulated with Microsoft Excel.

    Full Text Available TEMA: qualidade de vida em pacientes com doenças respiratórias. OBJETIVO: rever a literatura enfocando o impacto da asma, da rinite alérgica e da respiração oral na qualidade de vida do paciente, as relações entre essas morbidades e medidas que possam diminuir esse impacto. CONCLUSÃO: há consenso na literatura de que existe inter-relação dessas co-morbidades. O impacto da asma, rinite alérgica e respiração oral afetam diretamente a qualidade de vida do indivíduo não só pela alteração respiratória, mas, também pelos prejuízos comportamentais, funcionais e físicos que ocasionam. O controle dessas morbidades é um tema usual na literatura. Novas propostas terapêuticas englobam o envolvimento de equipes multiprofissionais. Há programas de saúde estruturados com essa visão e objetivam não só melhorar a condição respiratória, mas, também propõem medidas que analisam a qualidade de vida e possibilitam avaliação global do paciente.BACKGROUND: quality of life for patient with breathing illnesses. PURPOSE: to review specialized literature focusing on the impact of asthma, allergic rhinitis and mouth breathing on patient's life quality, the relationship between these illnesses and measures that can reduce this impact. CONCLUSION: it is a consensus in the specialized literature that there is a relationship between these illnesses. Asthma, allergic rhinitis and mouth breathing affect the person's life quality not only producing breathing disorder but also causing behavioral, functional and physical damage. Controlling these illnesses is a usual subject in the specialized literature. New therapeutic proposals include the involvement of multiprofessional teams. There are health programs whose goals are not only the improvement of respiratory condition. They also propose measures that analyze life quality and make possible patient's global evaluation.

  5. El principio de la responsabilidad civil objetiva limitada: un elemento de equilibrio sistémico que no contradice al denominado principio de la reparación integral del daño

    2014-07-01

    Full Text Available La tendencia moderna a objetivar la responsabilidad civil ha generado diferentes incoherencias sistémicas que exigen la introducción de elementos de equilibrio entre la responsabilidad subjetiva y la responsabilidad objetiva. Ante la permanente infracción al principio de la tipicidad, se propone como vía de equilibrio el reconocimiento del principio según el cual no puede haber responsabilidad objetiva sin limitación cuantitativa de la indemnización. Sin embargo, este principio entraría aparentemente en contradicción con otro, denominado principio de la reparación integral del daño. El artículo analiza dicha posible contradicción desde el fundamento moral de ambas clases de responsabilidad, así como del principio de la reparación integral del daño. Además, profundiza la problemática a partir de su elemento esencial, como es el daño resarcible, de modo de verificar qué elementos puede aportar a este aquel principio. En esta perspectiva, se estudia si tiene verdaderamente un carácter normativo, y qué cambios a su respecto produce su reconocimiento expreso a nivel legal o constitucional. Por último, se trata el principio de la reparación integral bajo un concepto distinto al tradicional y que ha venido sosteniéndose en los últimos años, a fin de confrontarlo con la citada contradicción. Al término del artículo, se sintetizan las conclusiones alcanzadas, las cuales concuerdan con la inexistencia de la contradicción entre el principio según el cual no hay responsabilidad objetiva sin limitación cuantitativa y el principio de la reparación integral del daño.

    To evaluate the feasibility of robot-assisted simulated cataract surgery. Institut de Recherche Contre les Cancers de l'Appareil Digestif, European Institute of Telesurgery, and Strasbourg University Hospital, Strasbourg, France. Experimental study. Cataract surgeries were performed on a Kitaro cataract wet-lab training system simultaneously using the Da Vinci Xi robotic surgical system and the Whitestar Signature phacoemulsification system. For each procedure, the duration and successful completion of the surgery with or without ocular complications were assessed. Procedures were successfully performed on 25 lens nuclei. The feasibility of robot-assisted simulated cataract surgery was confirmed. The robotic surgical system provided the intraocular dexterity and operative field visualization necessary to perform the main steps of the phacoemulsification procedure; that is, corneal incisions, capsulorhexis, grooving, cracking, quadrant removal, and irrigation/aspiration of the ophthalmic viscosurgical device (OVD). The intervention of a second surgeon was required for the intraocular injections of OVD, balanced salt solution, and intraocular lenses. The mean operative time was 26.44 minutes ± 5.15 (SD). All lens nuclei were removed. Inadvertent enlargement of the main corneal incision caused by the phaco handpiece was observed in 2 cases. Experimental robot-assisted cataract surgery was technically feasible using the new robotic surgical system combined with a phacoemulsification machine. Copyright © 2017 ASCRS and ESCRS.

    Full Text Available This work aims at demonstrating the inherent advantages of embracing a strong notion of social embodiment in designing a real-world robot control architecture with explicit ?intelligent? social behaviour between a collective of robots. It develops the current thinking on embodiment beyond the physical by demonstrating the importance of social embodiment. A social framework develops the fundamental social attributes found when more than one robot co-inhabit a physical space. The social metaphors of identity, character, stereotypes and roles are presented and implemented within a real-world social robot paradigm in order to facilitate the realisation of explicit social goals.

    Full Text Available A gestão da demanda emerge nos campos de conhecimentos da gestão da cadeia de suprimentos e de marketing. Busca-se a rápida e adequada integração das necessidades originadas do mercado na direção dos fornecedores, de modo a balancear e alinhar estrategicamente a demanda com a capacidade operacional ao longo da cadeia de suprimentos. O objetivo deste artigo é propor uma abordagem conceitual para a implantação de um processo efetivo de gestão da demanda em cadeias de suprimentos fornecendo uma visão mais ampla da gestão da demanda como um processo integrado e não uma atividade isolada ou resumida à previsão de vendas. Para o desenvolvimento desta abordagem, realizou-se uma ampla revisão da literatura, usando a metodologia da revisão sistemática de literatura. Os resultados apontam que o primeiro passo da abordagem conceitual consiste na compreensão do mercado por meio da análise das capacidades, restrições, oportunidades dos ambientes interno e externo à empresa. Este conhecimento ditará as diretrizes e práticas estratégicas e operacionais da organização. O processo de gestão da demanda envolve um time multifuncional composto por integrantes de diversos níveis e setores da organização, bem como representantes estratégicos da cadeia de suprimentos (fornecedores e clientes. Este time será responsável pelo desenvolvimento conjunto das previsões de vendas, da elaboração, execução e acompanhamento do plano de negócio. Para isto, os agentes internos e externos da cadeia precisam ter uma orientação para a cadeia de suprimentos. Uma implementação bem conduzida desta abordagem pode melhorar o nível de serviço prestado ao cliente e gerar benefícios substanciais para os resultados financeiros da empresa.Demand management emerges in knowledge fields of supply chain management and marketing.

    The aim of this paper is to sketch the basic motivations for “Integrative Social Robotics” (ISR), as a new paradigm for how to approach research, design, and development of social robotics applications that are culturally sustainable. I argue that social robotics saddles us with normative......-regulatory and descriptive questions that currently are kept too far apart. Currently HRI research investigates what social robots can do and robo-ethicists deliberate afterwards what robots should do. However, given the rapid pace of the robotics industry, descriptive and regulatory questions must be treated in combination....... On the ISR approach research in social robotics turns on what social robots can and should do--design and development are from the very beginning informed by value-theoretic and cultural research. ISR thus is a form of research organization that integrates robotics with empirical, conceptual, and value...

Acompanhado o desenvolvimento de sua teoria da modernidade e das conseqüências dessa teoria para a escrita da história e para a auto-consciência disciplinar. Por fim, proponho uma releitura da história da historiografia através dos dois tipos de culturas propostas por Gumbrecht, ou seja, culturas de sentido e culturas de presença. Argumento que mesmo que a historiografia moderna possa ser caracterizada como predominantemente ancorada na produção de sentido, aspectos centrais de sua história só podem ser explicados através de elementos típicos da produção de presença.This paper analyses some historiographical aspects of Hans Ulrich Gumbrecht's work, particularly his theory of modernity and its consequences to the writing of history and its disciplinary self-conscious. Finally, it is proposed a reinterpretation of the history of historiography based on the distinction between cultures of presence and cultures of meaning. It is argued that despite the fact that the elements of meaning are predominant in the constitution of modern historiography, the forces acting in its constitution cannot be explained without typical elements of a culture of presence.

    Full Text Available Resumen: El término Robots de Servicio apareció a finales de los años 80 como una necesidad de desarrollar máquinas y sistemas capaces de trabajar en entornos diferentes a los fabriles. Los Robots de Servicio tenían que poder trabajar en entornos noestructurados, en condiciones ambientales cambiantes y con una estrecha interacción con los humanos. En 1995 fue creado por la IEEE Robotics and Automation Society, el Technical Committee on Service Robots, y este comité definió en el año 2000 las áreas de aplicación de los Robots de Servicios, que se pueden dividir en dos grandes grupos: 1 sectores productivos no manufactureros tales como edificación, agricultura, naval, minería, medicina, etc. y 2 sectores de servicios propiamente dichos: asistencia personal, limpieza, vigilancia, educación, entretenimiento, etc. En este trabajo se hace una breve revisión de los principales conceptos y aplicaciones de los robots de servicio. Palabras clave: Robots de servicio, robots autónomos, robots de exteriores, robots de educación y entretenimiento, robots caminantes y escaladores, robots humanoides

    Full Text Available En este documento considera el tema de la responsabilidad del Estado en Colombia por la falla de la función legislativa, sea por la omisión legislativa absoluta o relativa y la declaración de inconstitucionalidad de la ley. Se tratan temas como la oposición o la restricción del legislador al derecho de reparación en aquellos casos en los que la misma ley que provoca un daño antijurídico, priva a un asociado de un derecho, o impide al mismo de la explotación de una actividad económica. Se consideran casos en los cuales la ley establece la pérdida del derecho de propiedad, pero por disposición de la misma ley, cualquier indemnización es excluida. Del mismo modo, se discute el tratamiento que la Corte Constitucional da al derecho de propiedad, cuando intenta diferenciar la regulación del derecho a la propiedad y la expropiación propiamente dicha. Se debaten los efectos de los resquicios de soberanía en algunos casos encontrados.

    Full Text Available A resistência de biótipos de plantas daninhas aos herbicidas inibidores da acetolactato sintase (ALS é causada pela insensibilidade desta enzima aos herbicidas que inibem sua atividade catalítica. A insensibilidade da enzima é decorrente de uma alteração estrutural, resultado da substituição de certos aminoácidos no sítio de ação do herbicida. Esta alteração na enzima pode eventualmente resultar, além da resistência ao herbicida, em modificações na taxa de crescimento da planta, fato este comprovado para os biótipos resistentes aos herbicidas inibidores do fotossistema II, os quais apresentam taxa de crescimento prejudicada pela alteração no sítio de ação sofrida pelo herbicida. Esta possível diminuição na taxa de crescimento da planta resistente tem conseqüências diretas na competitividade do biótipo e, portanto, na sua dinâmica dentro da população, afetando diretamente as estratégias de manejo da resistência. A presente pesquisa foi desenvolvida com o objetivo de comparar a taxa de crescimento de dois biótipos da planta daninha picão-preto (Bidens pilosa, sendo um resistente e um suscetível aos herbicidas inibidores da ALS. Um experimento foi montado em casa de vegetação, em vasos com capacidade de 5 L, sendo uma planta de cada biótipo por vaso, coletando-se a biomassa seca destas plantas e a área foliar semanalmente, iniciando-se 14 dias após o plantio. Os resultados de crescimento da biomassa e área foliar foram ajustados utilizando-se a função de Richards (log-logística. Desta análise, foram derivadas a taxa de crescimento absoluto (TCA, a taxa de crescimento relativo (TCR e a taxa de assimilação fotossintética líquida (TAL. O biótipo suscetível apresentou peso de biomassa seca superior ao resistente nas primeiras fases do crescimento, porém no final do ciclo o biótipo resistente igualou-se em tamanho de área foliar, pois apresentou, principalmente no início do ciclo de crescimento

    2011-10-01

    Despite the extensive use of robotics in the adult population, the use of robotics in pediatrics has not been well accepted. There is still a lack of awareness from pediatric surgeons on how to use the robotic equipment, its advantages and indications. Benefit is still controversial. Dexterity and better visualization of the surgical field are one of the strong values. Conversely, cost and a lack of small instruments prevent the use of robotics in the smaller patients. The aim of this manuscript is to present the controversies about the use of robotics in pediatric surgery.

    2016-02-01

    Nephron-sparing surgery has been proven to positively impact the postoperative quality of life for the treatment of small renal tumors, possibly leading to functional improvements. Laparoscopic partial nephrectomy is still one of the most demanding procedures in urological surgery. Laparoscopic partial nephrectomy sometimes results in extended warm ischemic time and severe complications, such as open conversion, postoperative hemorrhage and urine leakage. Robot-assisted partial nephrectomy exploits the advantages offered by the da Vinci Surgical System to laparoscopic partial nephrectomy, equipped with 3-D vision and a better degree in the freedom of surgical instruments. The introduction of the da Vinci Surgical System made nephron-sparing surgery, specifically robot-assisted partial nephrectomy, safe with promising results, leading to the shortening of warm ischemic time and a reduction in perioperative complications. Even for complex and challenging tumors, robotic assistance is expected to provide the benefit of minimally-invasive surgery with safe and satisfactory renal function. Warm ischemic time is the modifiable factor during robot-assisted partial nephrectomy to affect postoperative kidney function. We analyzed the predictive factors for extended warm ischemic time from our robot-assisted partial nephrectomy series. The surface area of the tumor attached to the kidney parenchyma was shown to significantly affect the extended warm ischemic time during robot-assisted partial nephrectomy. In cases with tumor-attached surface area more than 15 cm(2) , we should consider switching robot-assisted partial nephrectomy to open partial nephrectomy under cold ischemia if it is imperative. In Japan, a nationwide prospective study has been carried out to show the superiority of robot-assisted partial nephrectomy to laparoscopic partial nephrectomy in improving warm ischemic time and complications. By facilitating robotic technology, robot-assisted partial nephrectomy

    2016-01-01

    The intraoperative identification of certain anatomical structures because they are small or visually occult may be challenging. The development of minimally invasive surgery brought additional difficulties to identify these structures due to the lack of complete tactile sensitivity. A number of different forms of intraoperative mapping have been tried. Recently, the near-infrared fluorescence imaging technology with indocyanine green has been added to robotic platforms. In addition, this technology has been tested in several types of operations, and has advantages such as safety, low cost and good results. Disadvantages are linked to contrast distribution in certain clinical scenarios. The intraoperative near-infrared fluorescent imaging is new and promising addition to robotic surgery. Several reports show the utility of this technology in several different procedures. The ideal dose, time and site for dye injection are not well defined. No high quality evidence-based comparative studies and long-term follow-up outcomes have been published so far. Initial results, however, are good and safe. RESUMO A identificação intraoperatória de certas estruturas anatômicas, por seu tamanho ou por elas serem ocultas à visão, pode ser desafiadora. O desenvolvimento da cirurgia minimamente invasiva trouxe dificuldades adicionais, pela falta da sensibilidade tátil completa. Diversas formas de detecção intraoperatória destas estruturas têm sido tentadas. Recentemente, a tecnologia de fluorescência infravermelha com verde de indocianina foi associada às plataformas robóticas. Além disso, essa tecnologia tem sido testada em uma variedade de cirurgias, e suas vantagens parecem estar ligadas a baixo custo, segurança e bons resultados. As desvantagens estão associadas à má distribuição do contraste em determinados cenários. A imagem intraoperatória por fluorescência infravermelha é uma nova e promissora adição à cirurgia robótica. Diversas séries mostram

    Full Text Available Resumo Este trabalho teve como objetivo investigar a modificação de superfície do ZnAl1,9Eu0,05O4 visando a obtenção do híbrido ZnAl1,9Eu0,05O4/SiO2 para aplicação como biossensor. Inicialmente as nanopartículas de ZnAl1,9Eu0,05O4 foram sintetizadas por reação de combustão e, subsequentemente, as suas superfícies foram modificadas com o agente silano. As amostras foram caracterizadas por difração de raios X, microscopia eletrônica de varredura (MEV, espectroscopia de infravermelho com transformada de Fourier (FTIR e espectroscopia de excitação e de emissão. Os resultados evidenciaram a formação da fase majoritária do ZnAl2O4. Através de MEV observou-se a presença de aglomerados de aspecto duro, com formato irregular na forma de placas, com presença de poucos poros irregulares e variáveis. A modificação da superfície foi confirmada por FTIR através dos grupos silanóis e siloxanos. Os espectros de excitação e de emissão revelaram a presença de uma banda larga da matriz ZnAl2O4 e transições finas e intensas do íon európio provenientes da dopagem do óxido não estequiométrico ZnAl2O4 com o európio. Pelos resultados de emissão e excitação constatou-se que a luminescência do híbrido ZnAl1,9Eu0,05O4/SiO2 apresentou uma pequena diminuição em relação às nanopartículas de ZnAl1,9Eu0,05O4, sendo esta diminuição praticamente insignificante diante dos benefícios da silanização ocasionada pela introdução de grupos funcionais que promovem a conjugação do híbrido ZnAl1,9Eu0,05O4/SiO2 com biomoléculas, sendo este promissor para aplicação como biossensor aplicado na área biomédica para o diagnóstico e tratamento de doenças.

    Full Text Available Alumina based ceramics have important engineering applications due to their good physicochemical properties but their performance may be enhanced by addition of a second phase. Aluminosilicates as andalusite submitted to aluminium reduction and the simultaneous nitriding (N2 atmosphere leads to the obtention of alumina and phases of the Si-Al-O-N system. These phases are of great interest for structural ceramics. Mixes prepared with andalusite and Al° (different content were treated with N2 up to 1550 °C., using a heating rate of 5 °/min. Thermal effects (DTA and weight changes (TG, DTG of nitriding reactions during heating were evaluated. The reaction mechanism was determined using DTA-TG-DTG techniques. Results indicate that Si° and AlN are important intermediate phases during reactions. The final products were a-Al2O3 with sialons, mainly b’ phase and polytype sialons. The final formed phases depend on the Al° content and can be predicted using the Si-Al-O-N phase diagram.Cerâmicas à base de alumina apresentam importantes aplicações em engenharia por causa de suas boas propriedades físico-químicas; entretanto, seu desempenho pode ser melhorado pela adição de uma segunda fase.

    2014-01-01

    The purpose of this review is to compare conventional endovascular procedures and the robotic endovascular approach in aortic aneurysm repair. Despite advantages over open surgery, conventional endovascular surgery has limitations. To develop an alternative, efforts have been focused on robotic endovascular systems. Two of the 3 studies comparing procedure times demonstrated reduced procedure time in the robotic group, by 6 times (p robotic procedures reduced fluoroscopic exposure time by 12 minute (p robotic surgery was reduced up to 10 times (p robotic performance score showed a better performance score in the robotic endovascular group (p = 0.007). These results demonstrate that the robotic technique has multiple advantages over the conventional procedure, including improved catheter stability, a shorter learning curve, reduced procedure time, and better performance in cannulating tortuous vessels. However, robotic endovascular technology may be limited by the cost of the system, the size of the catheter, and the setup time required preoperatively. Further comparative studies between conventional and robotic approaches regarding cost-effectiveness, safety, and performance in cases involving complex anatomy and fenestrated stent grafts are essential. Nevertheless, this revolutionary technology is increasingly popular and may be the next milestone in endovascular surgery.

  15. Future robotic platforms in urologic surgery: recent developments.

    Herrell, S Duke; Webster, Robert; Simaan, Nabil

    2014-01-01

    To review recent developments at Vanderbilt University of new robotic technologies and platforms designed for minimally invasive urologic surgery and their design rationale and potential roles in advancing current urologic surgical practice. Emerging robotic platforms are being developed to improve performance of a wider variety of urologic interventions beyond the standard minimally invasive robotic urologic surgeries conducted currently with the da Vinci platform. These newer platforms are designed to incorporate significant advantages of robotics to improve the safety and outcomes of transurethral bladder surgery and surveillance, further decrease the invasiveness of interventions by advancing LESS surgery, and to allow for previously impossible needle access and ablation delivery. Three new robotic surgical technologies that have been developed at Vanderbilt University are reviewed, including a robotic transurethral system to enhance bladder surveillance and transurethral bladder tumor, a purpose-specific robotic system for LESS, and a needle-sized robot that can be used as either a steerable needle or small surgeon-controlled micro-laparoscopic manipulator.

    Assess the use and potential benefits of a new robotic system for transoral radical tonsillectomy, transoral supraglottic laryngectomy, and retroauricular thyroidectomy in a cadaver dissection. Three previously described robotic procedures (transoral radical tonsillectomy, transoral supraglottic laryngectomy, and retroauricular thyroidectomy) were performed in a cadaver using the da Vinci Xi Surgical System. Surgical exposure and access, operative time, and number of collisions were examined objectively. The new robotic system was used to perform transoral radical tonsillectomy with dissection and preservation of glossopharyngeal nerve branches, transoral supraglottic laryngectomy, and retroauricular thyroidectomy. There was excellent exposure without any difficulties in access. Robotic operative times (excluding set-up and docking times) for the 3 procedures in the cadaver were 12.7, 14.3, and 21.2 minutes (excluding retroauricular incision and subplatysmal elevation), respectively. No robotic arm collisions were noted during these 3 procedures. The retroauricular thyroidectomy was performed using 4 robotic ports, each with 8 mm instruments. The use of updated and evolving robotic technology improves the ease of previously described robotic head and neck procedures and may allow surgeons to perform increasingly complex surgeries. © The Author(s) 2015.

    2014-10-01

    The aim of the present review is to summarize recent developments in the field of urologic robotic surgery. A nonsystematic literature review was performed to retrieve publications related to robotic surgery in urology and evidence-based critical analysis was conducted by focusing on the literature of the past 5 years. The use of the da Vinci Surgical System, a robotic surgical system, has been implemented for the entire spectrum of extirpative and reconstructive laparoscopic kidney procedures. The robotic approach can be applied for a range of adrenal indications as well as for ureteral diseases, including benign and malignant conditions affecting the proximal, mid, and distal ureter. Current evidence suggests that robotic prostatectomy is associated with less blood loss compared with the open surgery. Besides prostate cancer, robotics has been used for simple prostatectomy in patients with symptomatic benign prostatic hyperplasia. Recent studies suggest that minimally invasive radical cystectomy provides encouraging oncologic outcomes mirroring those reported for open surgery. In recent years, the evolution of robotic surgery has enabled urologic surgeons to perform urinary diversions intracorporeally. Robotic vasectomy reversal and several other robotic andrological applications are being explored. In summary, robotic-assisted surgery is an emerging and safe technology for most urologic operations. The acceptance of robotic prostatectomy during the past decade has paved the way for urologists to explore the entire spectrum of extirpative and reconstructive urologic procedures. Cost remains a significant issue that could be solved by wider dissemination of the technology. Copyright © 2014 American Society for Reproductive Medicine. Published by Elsevier Inc.

  20. Para além da dupla consciência: Gestão Social e as antessalas epistemológicas

    Directory of Open Access Journals (Sweden)

    Carlos Eduardo Justen

    Full Text Available A partir da noção de dupla consciência, observada na obra The souls of black folk (1903, de W. E. B. Du Bois e utilizada como metarreferência discursiva, este artigo, como ensaio teórico, objetiva estabelecer uma reflexão epistemológica que contribua para que a Gestão Social não recaia na patologia da dupla consciência - uma gestão, na forma de ação social, que se credita normativamente emancipatória, mas que representa na materialidade da vida, de modo contraditório, a continuidade de uma realidade social opressora. Para tanto, após a identificação do sentido axiológico atribuído à Gestão Social e o apontamento das principais dificuldades, limitações e críticas mapeadas na literatura especializada, foram trazidas à baila duas temáticas pouco exploradas no âmbito da Gestão Social - relações de poder, consubstanciadas no conceito de colonialidade de poder, e a relação homem/natureza, delineada pelo aspecto da ecologia - a fim de demonstrar que tal gestão, uma gestão-problema, não uma gestão-resposta, deve desenvolver a capacidade de se autoproblematizar, de sentir-se como um problema e de refletir acerca de suas próprias questões não explicitadas. Ao final, após a exposição de um conjunto de caracteres epistemológicos, demonstrou-se que a Gestão Social, para não padecer das lacunas epistemológicas observadas na Gestão Estratégica, rompendo com a tendência de constituir uma antessala epistemológica, ao filtrar seletivamente as realidades observáveis e significativas e, dessa feita, mantendo a coesão social propiciada pela ideologia da gestão hegemônica, ela deve constituir a possibilidade plural de outras gestões, a partir de saberes e prática situados.

Considerando que o Déficit Máximo Acumulado de Oxigênio (MAOD representa a quantidade total de energia transferida pelos metabolismos anaeróbios, o objetivo desse estudo foi analisar se o método de subtrair o EPOCRÁPIDO do MAOD (MAODLA-1 proporciona uma estimativa satisfatória do metabolismo anaeróbio lático (MAL. Para esse fim, o MAODLA-1 foi comparado ao método capaz de expressar em equivalente de oxigênio a energia oriunda do acúmulo de lactato no sangue (MAODLA-2. Nove homens adultos ativos foram submetidos a quarto sessões experimentais: 1 um teste progressivo até a exaustão em um cicloergômetro para a mensuração do consumo máximo de oxigênio (VO2max e da potência externa correspondente ao O2max (WVO2max; 2 e 3 seis testes de cargas constantes (3 testes por sessão com intensidades abaixo da WVO2max; 4 um teste de carga constante com a intensidade equivalente a 110% da WVO2max. O principal achado foi que os dois métodos (MAODLA-1 e MAODLA-2 empregados na estimativa da contribuição do MAL no MAOD geraram valores estatisticamente similares (p > 0,05. Além disso, os valores percentuais do MAODLA-1 (representando o MAL e do EPOCRÁPIDO (representando o MAA foram de aproximadamente 78% e 22%, respectivamente. Logo, os procedimentos propostos na presente investigação podem auxiliar futuros trabalhos que porventura objetivem fragmentar as contribuições dos componentes anaeróbio do MAOD.

Assim, o human enhancement tornaria-se uma realidade antropotécnica tangível. Esse artigo, inserido em uma pesquisa do campo da Ethics of Enhancement Human Beings, pretende excogitar um novo conceito para compreender nuances da chamada Genetic Age até agora aparentemente negligenciadas por outros dois conceitos já disponíveis, a saber, biopolítica e biossociabilidade. Para tanto, recorremos à revisão de parte da bibliografia sobre o tema e à análise e crítica desses conceitos, os quais focalizam a temática fundamentalmente através das noções de gestão de riscos e promoção da vida saudável. O objetivo foi apontar a parcial pertinência da grade de inteligibilidade fornecida por eles para compreender a nova genética. Destarte, apresentamos o conceito de biodesign como uma alternativa complementar. Com ele, esperamos oferecer, introdutoriamente, um conceito que apreenda, sobretudo, o que as possibilidades de artificialização da vida humana representam para além de uma nova forma de gestão de riscos/promoção da saúde.The new genetics would point to a new era of metamorphosis of the human, which would be marked by the prominence of that in the selection and improvement of their nature.

    There are several publications that certify the excellent protection conferred to the steel for the aluminum covering against the corrosion. This covering represents an ideal commitment between the pure passive protection and the active protection. Moreover, the presence of Fe Al a intermetallic layer in the linking area between aluminum and the steel, possible of being made by thermal treatment, represents an additional protective barrier, in particular against the hydrogen diffusion into the steel. In industrial scale they are manufactured through the process of Alonization, steel pipes that require of a thermal treatment at 1050 deg C to allow the aluminium diffusion and and let grow up Fe Al intermetallic compound., which has recognized resistance to the sulphurous corrosive ways. This work presents Fe Al intermetallic formation results using the thermal spray technique to deposit aluminum and to carry it through posterior remelting of the aluminum covering. This procedure allows aluminum spread out on metallic surface and the formation of intermetallic rich in aluminum and other rich in iron. (author)

    It is highly desirable that automatic or remotely controlled machines perform inspection and maintenance tasks in nuclear facilities. Toshiba has been working to develop multi-functional robots, with one typical example being a master-slave manipulator for use in reprocessing facilities. At the same time, the company is also working on the development of multi-purpose intelligent robots. One such device, an automatic inspection robot, to be deployed along a monorail, performs inspection by means of image processing technology, while and advanced intelligent maintenance robot is equipped with a special wheel-locomotion mechanism and manipulator and is designed to perform maintenance tasks.

    Human-robot interaction (HRI) is a discipline investigating the factors affecting the interactions between humans and robots. It is important to evaluate how the design of interfaces affect the human's ability to perform tasks effectively and efficiently when working with a robot. By understanding the effects of interface design on human performance, workload, and situation awareness, interfaces can be developed to appropriately support the human in performing tasks with minimal errors and with appropriate interaction time and effort. Thus, the results of research on human-robot interfaces have direct implications for the design of robotic systems. For efficient and effective remote navigation of a rover, a human operator needs to be aware of the robot's environment. However, during teleoperation, operators may get information about the environment only through a robot's front-mounted camera causing a keyhole effect. The keyhole effect reduces situation awareness which may manifest in navigation issues such as higher number of collisions, missing critical aspects of the environment, or reduced speed. One way to compensate for the keyhole effect and the ambiguities operators experience when they teleoperate a robot is adding multiple cameras and including the robot chassis in the camera view. Augmented reality, such as overlays, can also enhance the way a person sees objects in the environment or in camera views by making them more visible. Scenes can be augmented with integrated telemetry, procedures, or map information. Furthermore, the addition of an exocentric (i.e., third-person) field of view from a camera placed in the robot's environment may provide operators with the additional information needed to gain spatial awareness of the robot. Two research studies investigated possible mitigation approaches to address the keyhole effect: 1) combining the inclusion of the robot chassis in the camera view with augmented reality overlays, and 2) modifying the camera

    This report contains the results of a research effort on advanced robot locomotion. The majority of this work focuses on walking robots. Walking robot applications include delivery of special payloads to unique locations that require human locomotion to exo-skeleton human assistance applications. A walking robot could step over obstacles and move through narrow openings that a wheeled or tracked vehicle could not overcome. It could pick up and manipulate objects in ways that a standard robot gripper could not. Most importantly, a walking robot would be able to rapidly perform these tasks through an intuitive user interface that mimics natural human motion. The largest obstacle arises in emulating stability and balance control naturally present in humans but needed for bipedal locomotion in a robot. A tracked robot is bulky and limited, but a wide wheel base assures passive stability. Human bipedal motion is so common that it is taken for granted, but bipedal motion requires active balance and stability control for which the analysis is non-trivial. This report contains an extensive literature study on the state-of-the-art of legged robotics, and it additionally provides the analysis, simulation, and hardware verification of two variants of a proto-type leg design.

    A small prototype mobile robot is capable of (1) hopping to move rapidly or avoid obstacles and then (2) moving relatively slowly and precisely on the ground by use of wheels in the manner of previously reported exploratory robots of the "rover" type. This robot is a descendant of a more primitive hopping robot described in "Minimally Actuated Hopping Robot" (NPO- 20911), NASA Tech Briefs, Vol. 26, No. 11 (November 2002), page 50. There are many potential applications for robots with hopping and wheeled-locomotion (roving) capabilities in diverse fields of endeavor, including agriculture, search-and-rescue operations, general military operations, removal or safe detonation of land mines, inspection, law enforcement, and scientific exploration on Earth and remote planets. The combination of hopping and roving enables this robot to move rapidly over very rugged terrain, to overcome obstacles several times its height, and then to position itself precisely next to a desired target. Before a long hop, the robot aims itself in the desired hopping azimuth and at a desired takeoff angle above horizontal. The robot approaches the target through a series of hops and short driving operations utilizing the steering wheels for precise positioning.

    Larrieu, Jacques

    2013-12-01

    This topic is part of the global issue concerning the necessity to adapt intellectual property law to constant changes in technology. The relationship between robots and IP is dual. On one hand, the robots may be regarded as objects of intellectual property. A robot, like any new machine, could qualify for a protection by a patent. A copyright may protect its appearance if it is original. Its memory, like a database, could be covered by a sui generis right. On the other hand, the question of the protection of the outputs of the robot must be raised. The robots, as the physical embodiment of artificial intelligence, are becoming more and more autonomous. Robot-generated works include less and less human inputs. Are these objects created or invented by a robot copyrightable or patentable? To whom the ownership of these IP rights will be allocated? To the person who manufactured the machine ? To the user of the robot? To the robot itself? All these questions are worth discussing.

    This study aimed to provide an overview of the literature on buccal mucosal ureteroplasty for ureteral stricture disease, with a specific focus on the application of the robotic platform to buccal ureteroplasty. In our review, we highlight the results of Zhao et al. from the New York University School of Medicine Department of Urology, as well as our own results from Temple University Hospital. Zhao et al. published the first series of four patients who underwent robotic buccal ureteroplasty. Mean stricture length was 3.0 cm, and at a mean follow-up of 15 months, all repairs remained patent. We also describe our results in 10 patients who underwent robotic buccal ureteroplasty at Temple University Hospital. Median stricture length was 3.0 cm, and at a median follow-up of 5 months, all repairs remain patent. Robotic buccal ureteroplasty offers a promising option for repair of complex ureteral strictures.

    The paper reports an important achievement in MRI instrumentation, a pneumatic, fully actuated robot located within the scanner alongside the patient and operating under remote control based on the images. Previous MRI robots commonly used piezoelectric actuation limiting their compatibility. Pneumatics is an ideal choice for MRI compatibility because it is decoupled from electromagnetism, but pneumatic actuators were hardly controllable. This achievement was possible due to a recent technology breakthrough, the invention of a new type of pneumatic motor, PneuStep 1, designed for the robot reported here with uncompromised MRI compatibility, high-precision, and medical safety. MrBot is one of the "MRI stealth" robots today (the second is described in this issue by Zangos et al.). Both of these systems are also multi-imager compatible, being able to operate with the imager of choice or cross-imaging modalities. For MRI compatibility the robot is exclusively constructed of nonmagnetic and dielectric materials such as plastics, ceramics, crystals, rubbers and is electricity free. Light-based encoding is used for feedback, so that all electric components are distally located outside the imager's room. MRI robots are modern, digital medical instruments in line with advanced imaging equipment and methods. These allow for accessing patients within closed bore scanners and performing interventions under direct (in scanner) imaging feedback. MRI robots could allow e.g. to biopsy small lesions imaged with cutting edge cancer imaging methods, or precisely deploy localized therapy at cancer foci. Our robot is the first to show the feasibility of fully automated in-scanner interventions. It is customized for the prostate and operates transperineally for needle interventions. It can accommodate various needle drivers for different percutaneous procedures such as biopsy, thermal ablations, or brachytherapy. The first needle driver is customized for fully automated low

    Combining the strengths of surgical robotics and minimally invasive surgery (MIS) holds the potential to revolutionize surgical interventions. The MIS advantages for the patients are obvious, but the use of instrumentation suitable for MIS often translates in limiting the surgeon capabilities (eg, reduction of dexterity and maneuverability and demanding navigation around organs). To overcome these shortcomings, the application of soft robotics technologies and approaches can be beneficial. The use of devices based on soft materials is already demonstrating several advantages in all the exploitation areas where dexterity and safe interaction are needed. In this article, the authors demonstrate that soft robotics can be synergistically used with traditional rigid tools to improve the robotic system capabilities and without affecting the usability of the robotic platform. A bioinspired soft manipulator equipped with a miniaturized camera has been integrated with the Endoscopic Camera Manipulator arm of the da Vinci Research Kit both from hardware and software viewpoints. Usability of the integrated system has been evaluated with nonexpert users through a standard protocol to highlight difficulties in controlling the soft manipulator. This is the first time that an endoscopic tool based on soft materials has been integrated into a surgical robot. The soft endoscopic camera can be easily operated through the da Vinci Research Kit master console, thus increasing the workspace and the dexterity, and without limiting intuitive and friendly use.

    Full Text Available If we make a brief scan of the field known as Medical Robotics, we find that in recent years there has been an impetuous development of applications involving medical robots. Obviously, the most spectacular are remote robotic surgery systems, which, for example, in U.S. have been used in more than 3.5-4 million interventions. The systems AESOP, da Vinci and ZEUS are currently run in minimally invasive robotic surgery. Encouraging results were obtained at MIT (USA using robots in physiotherapy. Pearl is a robot designed as personal assistant of older patients, affected by disabilities. The Universities of Pittsburgh and Carnegie Mellon successfully develop it. In Plymouth and Aachen, researchers are involved in the creation of intelligent wheelchairs. At the University of Karlsruhe, robotic systems applicable to neurosurgery are created. Thus, the MICRoN project aims to create a robot to manipulate micron-sized objects with nanometer precision, applications including intervention in the living biological cells. In several research centers one works on the improvement of neural interfaces, from which it is expected a new generation of prostheses, controlled through functional electrical stimulation. It is also projected that the microsystem technology (MST will have a major impact in medicine through the introduction of new diagnostic techniques, dosing, remote microsurgery and neural prostheses, all based on the concept of minimally invasive therapy, mentioned above. This is the approximate image of research in Medical Robotics and obviously of some related fields, whose dynamics has been impressive lately, a trend that is maintained and even has clear signs of amplification, and fully justifies this approach. In this context, we will present the main concepts and applications of medical robotics in order to achieve a more suggestive and convincing image of this area of great interest and perspective.

    To examine the feasibility of performing pelvic lymphadenectomy with robotic single site approach. Recent papers described the feasibility of robotic-single site hysterectomy [1-3] for benign and malign pathologies but only with the development of new single site 5mm instruments as the bipolar forceps, robotic single site platform can be safely utilized also for lymphadenectomy. A 65 year-old, multiparous patient with a body mass index of 22.5 and diagnosed with well differentiated adenocarcinoma of the endometrium underwent a robotic single-site peritoneal washing, total hysterectomy, bilateral adnexectomy and pelvic lymphadenectomy. The procedure was performed using the da Vinci Si Surgical System (Intuitive Surgical, Sunnyvale, CA) through a single 2,5 cm umbilical incision, with a multi-channel system and two single site robotic 5mm instruments. A 3-dimensional, HD 8.5mm endoscope and a 5mm accessory instrument were also utilized. Type I lymphonodes dissection for external iliac and obturator regions was performed [4]. Total operative time was 210 min; incision, trocar placement and docking time occurring in 12 min. Total console time was 183 min, estimated blood loss was 50 ml, no intra-operative or post-operative complications occurred. Hospital discharge occurred on post operative day 2 and total number of lymphnodes removed was 33. Difficulties in term of instrument's clashing and awkward motions have been encountered. Robotic single-site pelvic lymphadenectomy using bipolar forceps and monopolar hook is feasible. New developments are needed to improve surgical ergonomics and additional studies should be performed to explore possible benefits of this procedure. Copyright © 2014 Elsevier Inc.

    Full Text Available Concretos refratários no sistema Al2O3-SiC-C vêm sendo utilizados principalmente no revestimento de canais de corrida de altos-fornos. A associação dessas matérias-primas tem elevado o desempenho dos concretos refratários frente às severas condições de trabalho, devido ao aumento da resistência ao choque térmico e ao ataque por escória e metal fundido. Apesar disso, o nível de conhecimento científico sobre a dispersão das partículas desse sistema multifásico é limitado. Neste trabalho, suspensões representativas da matriz de concretos refratários zero-cimento no sistema Al2O3-SiC-C foram preparadas para a avaliação da eficiência de aditivos na dispersão simultânea de diferentes matérias-primas, bem como para a análise do comportamento reológico da matriz em função do pH e teor de aditivo. Os ácidos poliacrílico e cítrico e um surfactante não iônico foram usados como dispersantes. Os valores de viscosidade aparente e tensão de escoamento obtidos foram usados para construir mapas de estabilidade da matriz. Medidas de pH e fluidez de concretos preparados com diferentes teores de aditivo mostraram que as condições iniciais de pH não foram correspondentes à região ótima de dispersão estabelecida pelos mapas de estabilidade. O uso de altos teores de ácido cítrico, bem como, o deslocamento do pH do concreto na direção da região ótima de dispersão foram eficientes para otimizar a sua fluidez.Refractory castables in the Al2O3-SiC-C system have been used mainly as linings for blast furnace runners.

    Full Text Available Brachial plexus surgery using the da Vinci surgical robot is a new procedure. Although the supraclavicular approach is a well known described and used procedure for robotic surgery, axillary approach was unknown for brachial plexus surgery. A cadaveric study was planned to evaluate the robotic axillary approach for brachial plexus surgery. Our results showed that robotic surgery is a very useful method and should be used routinely for brachial plexus surgery and particularly for thoracic outlet syndrome. However, we emphasize that new instruments should be designed and further studies are needed to evaluate in vivo results.

    Since the 1990s, minimal access surgery has been utilized in urology. In the past 15 years, robotic surgery has evolved and become a natural part of minimal access surgery. The dissemination has been fast and the opportunity of prospective trials has been missed. Nevertheless, robotic surgery has obvious benefits for the surgeon and patient. Even though the scientific evidence is not strong, robotic surgery is here to stay. However, there are lessons to learn from the implementation of the da Vinci system with regards to patient safety and prospective evaluation of the new technology. The future of surgery will include technologies derived from robotic surgery.

    Modern technologies play a very important role in our lives. It is hard to imagine how people can get along without personal computers, and companies - without powerful computer centers. Nowadays, many devices make modern medicine more effective. Medicine is developing constantly, so introduction of robots in this sector is a very promising activity. Advances in technology have influenced medicine greatly. Robotic surgery is now actively developing worldwide. Scientists have been carrying out research and practical attempts to create robotic surgeons for more than 20 years, since the mid-80s of the last century. Robotic assistants play an important role in modern medicine. This industry is new enough and is at the early stage of development; despite this, some developments already have worldwide application; they function successfully and bring invaluable help to employees of medical institutions. Today, doctors can perform operations that seemed impossible a few years ago. Such progress in medicine is due to many factors. First, modern operating rooms are equipped with up-to-date equipment, allowing doctors to make operations more accurately and with less risk to the patient. Second, technology has enabled to improve the quality of doctors' training. Various types of robots exist now: assistants, military robots, space, household and medical, of course. Further, we should make a detailed analysis of existing types of robots and their application. The purpose of the article is to illustrate the most popular types of robots used in medicine.

    Frick, A C; Falcone, T

    2009-06-01

    Robotic surgery has evolved from an investigational surgical approach to a clinically useful adjunct in multiple surgical specialties over the past decade. Advocates of robotic-assisted gynecologic surgery revere the system's wristed instrumentation, ergonomic positioning, and three-dimensional high-definition vision system as significant improvements over laparoscopic equipment's four degrees of freedom and two-dimensional laparoscope that demand the surgeon stand throughout a procedure. The cost, lack of haptic feedback, and the bulky size of the equipment make robotics less attractive to others. Studies evaluating outcomes in robotic-assisted gynecologic surgery are limited. Multiple small retrospective studies demonstrate the safety and feasibility of robotic hysterectomy. With increased surgeon experience, operative times are similar to, or shorter than, laparoscopic cases. Robotic assistance can facilitate suturing in laparoscopic myomectomies, and is associated with decreased blood loss and a shorter hospital stay, although may require longer operative times. Robotic assistance has also been applied to multiple procedures in the subspecialties of infertility, urogynecology and gynecologic oncology with good success and relatively low morbidity. However, further research is warranted to better evaluate the relative benefits and costs of robotic assisted gynecologic surgery.

    2012-09-01

    The increasing complexity of intralumenal and emerging translumenal endoscopic procedures has created an opportunity to apply robotics in endoscopy. Computer-assisted or direct-drive robotic technology allows the triangulation of flexible tools through telemanipulation. The creation of new flexible operative platforms, along with other emerging technology such as nanobots and steerable capsules, can be transformational for endoscopic procedures. In this review, we cover some background information on the use of robotics in surgery and endoscopy, and review the emerging literature on platforms, capsules, and mini-robotic units. The development of techniques in advanced intralumenal endoscopy (endoscopic mucosal resection and endoscopic submucosal dissection) and translumenal endoscopic procedures (NOTES) has generated a number of novel platforms, flexible tools, and devices that can apply robotic principles to endoscopy. The development of a fully flexible endoscopic surgical toolkit will enable increasingly advanced procedures to be performed through natural orifices. The application of platforms and new flexible tools to the areas of advanced endoscopy and NOTES heralds the opportunity to employ useful robotic technology. Following the examples of the utility of robotics from the field of laparoscopic surgery, we can anticipate the emerging role of robotic technology in endoscopy.

    To investigate operators' performance quality, mental stress, and ergonomic habits through a training curriculum on robotic simulators. Forty volunteers without robotic surgery experience were recruited to practice 2 exercises on a dV-Trainer (dVT) for 14 hours. The simulator software (M-score a ) provided an automatic evaluation of the overall score for the surgeons' performance. Each participant provided a subjective difficulty score (validity to be proven) for each exercise. Their ergonomic habits were evaluated based on the workspace range and armrest load-validated criteria for evaluating the proficiency of using the armrest. They then repeated the same tasks on a da Vinci Surgical Skill Simulator for a final-level test. Their final scores were compared with their initial scores and the scores of 5 experts on the da Vinci Surgical Skill Simulator. A total of 14 hours of training on the dVT significantly improved the surgeons' performance scores to the expert level with a significantly reduced workload, but their ergonomic score was still far from the expert level. Sufficient training on the dVT improves novices' performance, reduces psychological stress, and inculcates better ergonomic habits. Among the evaluated criteria, novices had the most difficulty in achieving expert levels of ergonomic skills. The training benefits of robotic surgery simulators should be determined with quantified variables. The detection of the limitations during robotic training curricula could guide the targeted training and improve the training effect. Copyright © 2017. Published by Elsevier Inc.

    Since 2005 when the da Vinci surgical system was approved as a medical device by the Korean Ministry of Health and Welfare, 51 systems have been installed in 40 institutions as of May 2015. Although robotic surgery is not covered by the national health insurance service in Korea, it has been used in several urologic fields as a less invasive surgery. Since the first robotic-assisted laparoscopic radical prostatectomy in 2005, partial nephrectomy, radical cystectomy, pyeloplasty, and other urologic surgeries have been performed. The following should be considered to extend the indications for robotic surgery: training systems including accreditation, operative outcomes from follow-up results, and cost-effectiveness. In this review, the history and current status of robotic surgeries in Korea are presented.

    Robotic systems were introduced 15 years ago to support complex endoscopic procedures. The technology is increasingly used in gastro-intestinal surgery. In this article, literature on experimental- and clinical research is reviewed and ergonomic issues are discussed. literature review was based on Medline search using a large variety of search terms, including e.g. robot(ic), randomized, rectal, oesophageal, ergonomics. Review articles on relevant topics are discussed with preference. There is abundant evidence of supremacy in performing complex endoscopic surgery tasks when using the robot in an experimental setting. There is little high-level evidence so far on translation of these merits to clinical practice. Robotic systems may appear helpful in complex gastro-intestinal surgery. Moreover, dedicated computer based technology integrated in telepresence systems opens the way to integration of planning, diagnostics and therapy.

    Robots have been successfully used in commercial industry and have enabled humans to perform tasks which are repetitive, dangerous and requiring extreme force. Their role has evolved and now includes many aspects of surgery to improve safety and precision. Orthopaedic surgery is largely performed on bones which are rigid immobile structures which can easily be performed by robots with great precision. Robots have been designed for use in orthopaedic surgery including joint arthroplasty and spine surgery. Experimental studies have been published evaluating the role of robots in arthroscopy and trauma surgery. In this article, we will review the incorporation of robots in orthopaedic surgery looking into the evidence in their use. © The Authors, published by EDP Sciences, 2017.

    Although the use of robotic laparoscopic surgery has increased in popularity, training protocols for gaining proficiency in robotic surgical skills are not well established. The purpose of this study was to examine a fundamental training program that provides an effective approach to evaluate and improve robotic surgical skills performance using the da Vinci(™) Surgical System. Fifteen medical students without any robotic surgical experience were recruited. Participants went through a 4-day training program for developing fundamental robotic surgical skills and received a retention test 1 day after the completion of training. Data analysis included time to task completion, average speed, total distance traveled and movement curvature of the instrument tips, and muscle activities of the participants' forearms. Surgical performance was graded by the modified Objective Structured Assessment of Technical Skills for robotic laparoscopic surgery. Finally, participants evaluated their own performance after each session through questionnaires. Significant training effects were shown for the time to task completion (p movement curvature (p mastery, familiarity, and self-confidence and less difficulty in performing fundamental tasks with the surgical robot in both post-testing and retention sessions. Our 4-day training program comprising of a series of training tasks from fundamental to surgical skill levels was effective in improving surgical skills.

    Objectives: The objectives of this review are to summarize the current training modalities and assessment tools used in urological robotic surgery and to propose principles to guide the formation of a comprehensive robotics curriculum. Materials and Methods: The PUBMED database was systematically searched for relevant articles and their citations utilized to broaden our search. These articles were reviewed and summarized with a focus on novel developments. Results: A multitude of training modalities including didactic, dry lab, wet lab, and virtual reality have been developed. The use of these modalities can be divided into basic skills-based exercises and more advanced procedure-based exercises. Clinical training has largely followed traditional methods of surgical teaching with the exception of the unique development of tele-mentoring for the da Vinci interface. Tools to assess both real-life and simulator performance have been developed, including adaptions from Fundamentals of Laparoscopic Surgery and Objective Structured Assessment of Technical Skill, and novel tools such as Global Evaluative Assessment of Robotic Skills. Conclusions: The use of these different entities to create a standardized curriculum for robotic surgery remains elusive. Selection of training modalities and assessment tools should be based upon performance data-based validity and practical feasibility. Comparative assessment of different modalities (cross-modality validity) can help strengthen the development of common skill sets. Constant data collection must occur to guide continuing curriculum improvement. PMID:25097322

    The Nuclear and Energy Research Institute - IPEN-CNEN/SP produces routinely the nuclear fuel necessary for operating its research reactor, IEA-R1. This fuel consists of fuel plates containing U{sub 3}Si{sub 2}-Al composites as the meat, which are fabricated by rolling. The rolling process currently deployed was developed with base on information obtained from literature, which were used as premises for defining the current manufacturing procedures, according to a methodology with essentially empirical character. Despite the current rolling process to be perfectly stable and highly reproducible, it is not well characterized and therefore is not fully known. The objective of this work is to characterize the rolling process for producing fuel plates, specifically the evolution of dimensional parameters of the fuel plate as a function of its deformation in the rolling process. Results are presented in terms of the evolution of the thickness of the fuel meat and cladding of the fuel plate along the deformation, as well as the terminals defects, microstructure and porosity of the fuel meat.

    The corrosion behavior of the CuAlNi shape memory alloy in oil landfield produced groundwater was investigated with polarization curve and mass loss measurements, the latter carried out by immersion in laboratory and field tests. The physico-chemical analysis of five types of oil landfield produced groundwater showed the presence of H{sub 2}S and CO{sub 2}, high salinity, chloride, sulfide and iron ions and relatively neutral pH. The results from electrochemical tests in aerated produced groundwater, in the range of salinity encountered, suggested that the corrosion rate increases at higher saline concentrations. The results from field tests with corrosion test specimens showed a moderate to severe corrosion rate and suggested, in the other hand, that corrosion rates were influenced not only by salinity and oxidizing ions present in the flowing fluid, but also by solid materials in suspension, the fluid's temperature, and the flow velocity. This research is part of a major project which aims to develop couplings for landfield produced fluid transportation pipe connections without welded nor threaded joints. (author)

    Low intensity GaAlAs ({lambda}=830 nm) laser irradiation effects on oral traumatic ulceration were evaluated. For this purpose, twenty patients presenting orthodontic appliance - induced oral traumatic ulceration were randomly distributed in two groups. Patients in group 1 were submitted to the irradiation procedure and group 2 was the control one. The irradiation parameters employed were the following: wavelength 830 nm, one single application of 4 J/cm{sup 2}, punctual in the contact mode and 30 mW power. The control group received the conventional treatment, consisting on topical application of Triancinolon based ointment four times a day. For both groups the agent responsible for the trauma was removed or covered with utility wax whenever removal was impossible. The results were evaluated concerning the wounds size reduction and pain relief. The time of laser irradiation was considered the starting time (time zero) and analysis were done 24 hours, 48 hours and seven days after that. The statistical analysis showed an acceleration in the healing process as well accentuated pain reduction for the irradiated group compared to the control one. These evidences allows us to indicate this protocol of one single application of 4 J/cm{sup 2} as therapy when patients with oral traumatic ulceration can not attend several sessions for a multiple application procedure.

    Synopsis Genes linked to ALS susceptibility are being identified at an increasing rate owing to advances in molecular genetic technology. Genetic mechanisms in ALS pathogenesis appear to exert major effects in ~10% of patients, but genetic factors at some level may be important components of disease risk in most ALS patients. Identification of gene variants associated with ALS has informed concepts of the pathogenesis of ALS, aided the identification of therapeutic targets, facilitated research to develop new ALS biomarkers, and supported the establishment of clinical diagnostic tests for ALS-linked genes. Translation of this knowledge to ALS therapy development is ongoing. PMID:26515623

    2009-05-01

    Our long-term goal is to develop autonomous robotic systems that have the cognitive abilities of humans, including communication, coordination, adapting to novel situations, and learning through experience. Our approach rests on the recent integration of the Soar cognitive architecture with both virtual and physical robotic systems. Soar has been used to develop a wide variety of knowledge-rich agents for complex virtual environments, including distributed training environments and interactive computer games. For development and testing in robotic virtual environments, Soar interfaces to a variety of robotic simulators and a simple mobile robot. We have recently made significant extensions to Soar that add new memories and new non-symbolic reasoning to Soar's original symbolic processing, which should significantly improve Soar abilities for control of robots. These extensions include episodic memory, semantic memory, reinforcement learning, and mental imagery. Episodic memory and semantic memory support the learning and recalling of prior events and situations as well as facts about the world. Reinforcement learning provides the ability of the system to tune its procedural knowledge - knowledge about how to do things. Mental imagery supports the use of diagrammatic and visual representations that are critical to support spatial reasoning. We speculate on the future of unmanned systems and the need for cognitive robotics to support dynamic instruction and taskability.

  12. Door breaching robotic manipulator

    2008-04-01

    As unmanned systems become more commonplace in military, police, and other security forces, they are tasked to perform missions that the original hardware was not designed for. Current military robots are built for rough outdoor conditions and have strong inflexible manipulators designed to handle a wide range of operations. However, these manipulators are not well suited for some essential indoor tasks, including opening doors. This is a complicated kinematic task that places prohibitively difficult control challenges on the robot and the operator. Honeybee and iRobot have designed a modular door-breaching manipulator that mechanically simplifies the demands upon operator and robot. The manipulator connects to the existing robotic arm of the iRobot PackBot EOD. The gripper is optimized for grasping a variety of door knobs, levers, and car-door handles. It works in conjunction with a compliant wrist and magnetic lock-out mechanism that allows the wrist to remain rigid until the gripper has a firm grasp of the handle and then bend with its rotation and the swing of the door. Once the door is unlatched, the operator simply drives the robot through the doorway while the wrist compensates for the complex, multiple degree-of-freedom motion of the door. Once in the doorway the operator releases the handle, the wrist pops back into place, and the robot is ready for the next door. The new manipulator dramatically improves a robot's ability to non-destructively breach doors and perform an inspection of a room's content, a capability that was previously out of reach of unmanned systems.

  13. Fome, desnutrição e pobreza: além da semântica Hunger, malnutrition and poverty: beyond the semantics

    Full Text Available Fome, desnutrição e pobreza são problemas de natureza, dimensão e tendências muito distintas no Brasil, comportando soluções com escala, investimentos e conteúdos distintos. Ações governamentais de combate à pobreza certamente merecem máxima prioridade, justificam grandes investimentos e devem perseguir essencialmente o aumento da renda dos mais pobres. Ações que resultem em maior crescimento econômico com melhor distribuição de renda e que levem à reativação da economia, à criação de empregos e ao aprofundamento da reforma agrária são vistas como soluções consensuais no país. Mais recentemente, o mesmo acordo parece existir quanto a programas governamentais de transferência direta de renda acoplados a contrapartidas das famílias beneficiárias, seja com relação à manutenção das crianças nas escolas (bolsa-escola, seja com relação a controles preventivos de saúde (bolsa alimentação. Ações que combatam eficientemente a pobreza serão obviamente de enorme valia para a luta contra a desnutrição. Entretanto, a experiência nacional e internacional mostra que a intensificação dos investimentos em educação, saneamento do meio e cuidados básicos de saúde será essencial para se alcançar a erradicação da desnutrição. A luta contra a fome, ou ao que resta desse problema no país, igualmente se beneficiará do combate à pobreza. Contudo, as evidências indicam que ações específicas de combate à fome, em particular ações de distribuição de alimentos (diretamente ou através de créditos ou cupons, deveriam ser empregadas no Brasil de modo limitado e apenas em condições excepcionais e devidamente justificadas. A expansão desmedida de ações de distribuição de alimentos, ao contrário do que talvez indiquem o senso comum e a indignação justificada diante de uma sociedade tão injusta como a brasileira, implicaria apenas consumir recursos que poderiam faltar para ações sociais melhor

    The application of robots in the harsh environments in which TELEMAN equipment will have to operate has large benefits, but also some drawbacks. The main benefit is the ability gained to perform tasks where people cannot go, while there is a possibility of inflicting damage to the equipment handled by the robot, and the plant when mobile robots are involved. The paper describes the types of possible damage and the precautions to be taken in order to reduce the frequency of the damaging events. A literature study for the topic only gave some insight into examples, but no means for a systematic treatment of the topic. (au) 16 refs

    An architecture for robot intelligence enables a robot to learn new behaviors and create new behavior sequences autonomously and interact with a dynamically changing environment. Sensory information is mapped onto a Sensory Ego-Sphere (SES) that rapidly identifies important changes in the environment and functions much like short term memory. Behaviors are stored in a DBAM that creates an active map from the robot's current state to a goal state and functions much like long term memory. A dream state converts recent activities stored in the SES and creates or modifies behaviors in the DBAM.

    2014-01-01

    The remarkable advances of robotics in the last 50 years, which represent an incredible wealth of knowledge, are based on the fundamental assumption that robots are chains of rigid links. The use of soft materials in robotics, driven not only by new scientific paradigms (biomimetics, morphological computation, and others), but also by many applications (biomedical, service, rescue robots, and many more), is going to overcome these basic assumptions and makes the well-known theories and techniques poorly applicable, opening new perspectives for robot design and control. The current examples of soft robots represent a variety of solutions for actuation and control. Though very first steps, they have the potential for a radical technological change. Soft robotics is not just a new direction of technological development, but a novel approach to robotics, unhinging its fundamentals, with the potential to produce a new generation of robots, in the support of humans in our natural environments.

    Full Text Available A novel concept of media education called “robot literacy” is proposed. Here, robot literacy refers to the means of forming an appropriate relationship with intelligent robots. It can be considered a kind of media literacy. People who were born after the Internet age can be considered “digital natives” who have new morals and values and behave differently than previous generations in Internet societies. This can cause various problems among different generations. Thus, the necessity of media literacy education is increasing. Internet technologies, as well as robotics technologies are growing rapidly, and people who are born after the “home robot age,” whom the author calls “robot natives,” will be expected to have a certain degree of “robot literacy.” In this paper, the concept of robot literacy is defined and an approach to robot literacy education is discussed.

    Limited autonomous behaviors are fast becoming a critical capability in the field of robotics as robotic applications are used in more complicated and interactive environments. As additional sensory capabilities are added to robotic platforms, sensor fusion to enhance and facilitate autonomous behavior becomes increasingly important. Using biology as a model, the equivalent of a vestibular system needs to be created in order to orient the system within its environment and allow multi-modal sensor fusion. In mammals, the vestibular system plays a central role in physiological homeostasis and sensory information integration (Fuller et al, Neuroscience 129 (2004) 461-471). At the level of the Superior Colliculus in the brain, there is multimodal sensory integration across visual, auditory, somatosensory, and vestibular inputs (Wallace et al, J Neurophysiol 80 (1998) 1006-1010), with the vestibular component contributing a strong reference frame gating input. Using a simple model for the deep layers of the Superior Colliculus, an off-the-shelf 3-axis solid state gyroscope and accelerometer was used as the equivalent representation of the vestibular system. The acceleration and rotational measurements are used to determine the relationship between a local reference frame of a robotic platform (an iRobot Packbot®) and the inertial reference frame (the outside world), with the simulated vestibular input tightly coupled with the acoustic and optical inputs. Field testing of the robotic platform using acoustics to cue optical sensors coupled through a biomimetic vestibular model for "slew to cue" gunfire detection have shown great promise.

    Beck, Anders Billesø

    Mobile robots have become a mature technology. The first cable guided logistics robots were introduced in the industry almost 60 years ago. In this time the market for mobile robots in industry has only experienced a very modest growth and only 2.100 systems were sold worldwide in 2011. In recent...... years, many other domains have adopted the mobile robots, such as logistics robots at hospitals and the vacuum robots in our homes. However, considering the achievements in research the last 15 years within perception and operation in natural environments together with the reductions of costs in modern...... sensor systems, the growth potential for mobile robot applications are enormous. Many new technological components are available to move the limits of commercial mobile robot applications, but a key hindrance is reliability. Natural environments are complex and dynamic, and thus the risk of robots...

    Soft robotics and its related technologies enable robot abilities in several robotics domains including, but not exclusively related to, manipulation, manufacturing, human-robot interaction and locomotion. Although field applications have emerged for soft manipulation and human-robot interaction, mobile soft robots appear to remain in the research stage, involving the somehow conflictual goals of having a deformable body and exerting forces on the environment to achieve locomotion. This paper aims to provide a reference guide for researchers approaching mobile soft robotics, to describe the underlying principles of soft robot locomotion with its pros and cons, and to envisage applications and further developments for mobile soft robotics. © 2017 The Author(s).

  3. Continuum limbed robots for locomotion

    Science.gov (United States)

    Mutlu, Alper

    This thesis focuses on continuum robots based on pneumatic muscle technology. We introduce a novel approach to use these muscles as limbs of lightweight legged robots. The flexibility of the continuum legs of these robots offers the potential to perform some duties that are not possible with classical rigid-link robots. Potential applications are as space robots in low gravity, and as cave explorer robots. The thesis covers the fabrication process of continuum pneumatic muscles and limbs. It also provides some new experimental data on this technology. Afterwards, the designs of two different novel continuum robots - one tripod, one quadruped - are introduced. Experimental data from tests using the robots is provided. The experimental results are the first published example of locomotion with tripod and quadruped continuum legged robots. Finally, discussion of the results and how far this technology can go forward is presented.

    The principal objective of the experiment was to analyze the effects of the clutch operation of robotic surgical systems on the performance of the operator. The relative coordinate system introduced by the clutch operation can introduce a visual-perceptual mismatch which can potentially have negative impact on a surgeon's performance. We also assess the impact of the introduction of additional tactile sensory information on reducing the impact of visual-perceptual mismatch on the performance of the operator. We asked 45 novice subjects to complete peg transfers using the da Vinci IS 1200 system with grasper-mounted, normal force sensors. The task involves picking up a peg with one of the robotic arms, passing it to the other arm, and then placing it on the opposite side of the view. Subjects were divided into three groups: aligned group (no mismatch), the misaligned group (10 cm z axis mismatch), and the haptics-misaligned group (haptic feedback and z axis mismatch). Each subject performed the task five times, during which the grip force, time of completion, and number of faults were recorded. Compared to the subjects that performed the tasks using a properly aligned controller/arm configuration, subjects with a single-axis misalignment showed significantly more peg drops (p = 0.011) and longer time to completion (p mismatch in some cases. Grip force data recorded from grasper-mounted sensors showed no difference between the different groups. The visual-perceptual mismatch created by the misalignment of the robotic controls relative to the robotic arms has a negative impact on the operator of a robotic surgical system. Introduction of other sensory information and haptic feedback systems can help in potentially reducing this effect.

    Over the past few decades, robotic surgery has developed from a futuristic dream to a real, widely used technology. Today, robotic platforms are used for a range of procedures and have added a new facet to the development and implementation of minimally invasive surgeries. The potential advantages are enormous, but the current progress is impeded by high costs and limited technology. However, recent advances in haptic feedback systems and single-port surgical techniques demonstrate a clear role for robotics and are likely to improve surgical outcomes. Although robotic surgeries have become the gold standard for a number of procedures, the research in colorectal surgery is not definitive and more work needs to be done to prove its safety and efficacy to both surgeons and patients.

    2015-01-01

    Robotic surgery was initially developed to overcome problems faced during conventional laparoscopic surgeries and to perform telesurgery at distant locations. It has now established itself as the epitome of minimally invasive surgery (MIS). It is one of the most significant advances in MIS in recent years and is considered by many as a revolutionary technology, capable of influencing the future of surgery. After its introduction to urology, robotic surgery has redefined the management of urological malignancies. It promises to make difficult urological surgeries easier, safer and more acceptable to both the surgeon and the patient. Robotic surgery is slowly, but surely establishing itself in India. In this article, we provide an overview of the advantages, disadvantages, current status, and future applications of robotic surgery for urologic cancers in the context of the Indian scenario.

    We present the robot art and how it may inspire to create a new type of wearable termed modular robotic wearable. Differently from the related works, modular robotic wearable aims at making no use of mechatronic devices (as, for example, in Cyberpunk and related research branches) and mostly relies...... on “simple” plug-and-play circuits, ranging from pure sensors-actuators schemes to artefacts with a smaller level of elaboration complexity. Indeed, modular robotic wearable focuses on enhancing the body perception and proprioperception by trying to substitute all of the traditional exoskeletons perceptive...... functions - in most of the cases strongly rigid, cabled and centralized - through the use of local sensing circuits. It is exemplified here with the early prototype art work called Fatherboard, and the concept is believed to be applicable to different application fields, such as sport, health...

    In nature, nanometer-scale molecular motors are used to generate force within cells for diverse processes from transcription and transport to muscle contraction. This adaptability and scalability across wide temporal, spatial, and force regimes have spurred the development of biological soft robotic systems that seek to mimic and extend these capabilities. This review describes how molecular motors are hierarchically organized into larger-scale structures in order to provide a basic understanding of how these systems work in nature and the complexity and functionality we hope to replicate in biological soft robotics. These span the subcellular scale to macroscale, and this article focuses on the integration of biological components with synthetic materials, coupled with bioinspired robotic design. Key examples include nanoscale molecular motor-powered actuators, microscale bacteria-controlled devices, and macroscale muscle-powered robots that grasp, walk, and swim. Finally, the current challenges and future opportunities in the field are addressed.

  15. Robots in Elderly Care

    Full Text Available Low birth rate and the long life expectancy represent an explosive mixture, resulting in the rapid aging of population. The costs of healthcare in the grey society are increasing dramatically, and soon there will be not enough resources and people for care. This context requires conceptually new elderly care solutions progressively reducing the percentages of the human-based care. Research on robot-based solutions for elderly care and active ageing aims to answer these needs. From a general perspective, robotics has the power to completely reshape the landscape of healthcare both in its structure and its operation. In fact, the long-term sustainability of healthcare systems could be addressed by automation powered by digital health technologies, such as artificial intelligence, 3D-printing or robotics. The latter could take over monotonous work from healthcare workers, which would allow them to focus more on patients and to have lesser workload. Robots might be used in elder care with several different aims. (i Robots may act as caregivers, i.e. assist the elderly, (ii they can provide remainders and instructions for activities of daily life and safety, and/or assist their carers in daily tasks; (iii they can help monitor their behaviour and health; and (iv provide companionship, including entertainment and hobbies, reminiscence and social contact. The use of Robots with human subjects/patients raise several sensitive questions. First of all, robots may represent information hubs, and can collect an incredible amount of data about the subjects and their environment. In fact, they record habits such as sleeping, exercising, third persons entering in the house, appointments. Communications may be continuously recorded. Moreover, by connecting with medical devices, they can store medical data. On one hand, this represents a very powerful tool to collect information about the single subject (precision medicine, about disease (thus eventually finding
