摘要： Background: Laparoscopy and more recently robotics are increasingly used for colorectal cancer surgery in the United States. We examined the current trends of minimally invasive surgical resections for colorectal cancer in Florida. Methods: The Florida Inpatient Discharge Dataset was used to examine the clinical data of patients who underwent elective surgery for colorectal cancer during 2013-2015. Multivariate analyses were performed to compare patient characteristics associated with the use of open and minimally invasive surgeries. Results: A total of 10,513 patients were analyzed;5451 (52%) had open surgery, 4403 (42%) laparoscopy, and 659 (6%) robotic surgery. The rates of minimally invasive surgery (MIS) increased from 46.95% in 2013 to 48.72% in 2015. Among minimally invasive surgical procedures, the use of robotics increased from 9.82% in 2013 to 15.48% in 2015. Metastatic cancer (odds ratio [OR] 0.61, confidence interval [CI] 0.55-0.67), Elixhauser score of 3-5 (OR 0.85, CI 0.76-0.95) or more than 5 (OR 0.78, CI 0.63-0.97), Medicaid insurance (OR 0.73, CI 0.6-0.89), Black race (OR 0.88, CI 0.77-0.99), and rural residence (OR 0.83, CI 0.69-0.99) were associated with lower odds of MIS than open surgery. Conclusions: This study demonstrates that the overall rates of MIS for colorectal cancer in Florida increased from 2013 to 2015. Socially deprived and very sick patient populations with colorectal cancer are less likely to undergo MIS.

摘要： Medical surgical robot is a fusion of medical image information matching fusion technology and robotic trajectory control technology. The medical image information matching fusion is to obtain two images of a certain range of the patient's body by two cameras on the robot, and after matching fusion processing, an image is obtained. At present, surgical robots have been successfully applied in minimally invasive surgery such as pelvic organ prolapse, defects and other basin basement reconstruction operations. Previously, most of the robots used in medical surgery have only one arm, but with the development of robotics related fields, multi-fingered robots with binocular stereo vision become possible in completing complex minimally invasive surgery. This paper aims to promote the further integration of multi-fingered manipulator and medical image detection, focusing on the grasping probability of multi-fingered manipulator. When the three-dimensional information of the object is incomplete, the machine learning method performs better than the hard coding method in the object grasping point planning. At present, most known methods can obtain classification results but could not give the probability of this category. Aiming at the problem of grab point planning, this paper proposes a crawling planning method based on big data Gaussian process classification. In this paper, a planner based on Gaussian process classification is designed, and the hyper constant used in the Gaussian process to judge the probability of capture is calculated. Based on the determined crawling scheme, the feasibility distribution map of the grab points which obtained by the trained Gaussian process classifier is drawn in MATLAB. The results show that the trained Gaussian process classifier is biased towards the center of the object which is the point with high stability. This method can give classification results and corresponding probabilities, which represents the feasibility of grasping poi

摘要： In this article, a noble ionic polymer metal composite (IPMC) based on sulfonated polyvinyl alcohol (SPVA) and 1-ethyl-3-methylimidazolium tetrachloro aluminate (IL) with deposited Pt was fabricated and used to develop flexible link manipulator. The proposed IPMC was fabricated by simple solution casting method using SPVA and IL with deposited Pt metal by electroless plating method. Herein, SPVA polymer membrane acts as a medium for metal ion migration, and the Pt act as the surface conductive electrode on both sides of the membrane surface. Experimental characterizations such as scanning electron microscopy, cyclic voltammetry and linear sweep voltammetry, load characterization, and actuation performance confirm the excellent electrochemical and electromechanical response as compared with the other reported IPMCs. This method of fabrication exhibits significant advantages, such as the easy process of fabrication using non-toxic materials. A two-link flexible manipulator was developed, where the electromechanical behavior of polymer-based actuator provides an important step for robotic assembly. This shows the potential of flexible compliant fingers and joints in flexible link manipulator for robotic assembly. POLYM. COMPOS., 40:2582-2593, 2019. (c) 2018 Society of Plastics Engineers

摘要： This meta-analysis examines the effects of learning with robots (r-learning) on young children and, on this basis, gives suggestions for using robotics in education for young children. A test of homogeneity was performed for 27 Korean studies done between 2008 and 2016 and a random effect model introduced to reveal the effect sizes. The overall effect size was medium to large at 0.72. After analyzing gaps in effect sizes with different categorical moderator variables, the authors found significant differences depending on platform type, activity type, dependent variables for r-learning effect, and age. The study also investigates relationships between effect size and continuous moderator variables such as treatment period and year of publication. The meta-regression model showed a significantly negative relationship between effect size and year of publication. Thus, effects of r-learning on a young child are generally beneficial, and r-learning also improves variables like a child's social nature, though conversely the effect on language development appears below average.
