Geotechnical investigations of site and bearing capacity analysis are very important procedures for construction of building. Plate loading test is conventional method usually used to measure a bearing capacity of ground directly. But this method is not used widely because it needs large measurement space, long time for measurement and rather costly for single house foundation survey. Therefore, development of easy and cheapest way of bearing capacity survey is keen interest of Japanese geotechnical engineers. In this context, the authors have developed a portable ground bearing capacity survey instruments that could solve aforesaid problems associated with plate loading test. The relationship curve between the loading pressure and penetration directly gives the ground bearing capacity value.

Objective: The aim of this study was to explore the prevalence of attention deficit hyperactivity disorder (ADHD) and/or autism spectrum disorder (ASD) and its relation to lifestyle in female college students. Subjects and methods: A total of 375 female college students (19.2 ± 1.3 years) among 439 students were enrolled in this cross-sectional study. Using a self-reported questionnaire, we measured the prevalence of ADHD using the ADHD Self-Report Scale-v1.1 (ASRS) and the prevalence of ASD using the Autism-Spectrum Quotient (AQ). In addition, lifestyle choices such as medications, physical activity, cigarette smoking, alcohol drinking and sleeping habits were also evaluated. Results: The suspected prevalence of ADHD was 102 students (27.2 %) and the suspected prevalence of ASD was 4 students (1.1 %). Only one student (0.3 %) was thought to have both ADHD and ASD. Subjects with suspected ADHD had higher AQ scores compared with those without suspected ADHD. There were no unhealthy lifestyle choices in subjects with suspected ADHD and/or ASD. Conclusion: The prevalence of suspected ADHD and/or ASD may be relatively high even among female college students in Japan. © 2016 The Japanese Society for Hygiene

Background: Endovascular surgery benefits patients because of its superior short convalescence and lack of damage to healthy tissue. However, such advantages require the operator to be equipped with dexterous skills for catheter manipulation without resulting in collateral damage. To achieve this goal, a training system is in high demand. Methods: A training system integrating a VR simulator and a haptic device has been developed within this context. The VR simulator is capable of providing visual cues which assist the novice for safe catheterization. In addition, the haptic device cooperates with VR simulator to apply sensations at the same time. The training system was tested by non-medical subjects over a five days training session. Results: The performance was evaluated in terms of safety criteria and task completion time. The results demonstrate that operation safety is improved by 15.94% and task completion time is cut by 18.80s maximum. Moreover, according to subjects' reflections, they are more confident in operation. Conclusions: The proposed training system constructs a comprehensive training environment that combines visualization and force sensation. © 2016 John Wiley & Sons, Ltd.

Background: An Internet-based tele-operative robotic catheter operating system was designed for vascular interventional surgery, to afford unskilled surgeons the opportunity to learn basic catheter/guidewire skills, while allowing experienced physicians to perform surgeries cooperatively. Remote surgical procedures, limited by variable transmission times for visual feedback, have been associated with deterioration in operability and vascular wall damage during surgery. Methods: At the patient's location, the catheter shape/position was detected in real time and converted into three-dimensional coordinates in a world coordinate system. At the operation location, the catheter shape was reconstructed in a virtual-reality environment, based on the coordinates received. The data volume reduction significantly reduced visual feedback transmission times. Results: Remote transmission experiments, conducted over inter-country distances, demonstrated the improved performance of the proposed prototype. The maximum error for the catheter shape reconstruction was 0.93 mm and the transmission time was reduced considerably. Conclusions: The results were positive and demonstrate the feasibility of remote surgery using conventional network infrastructures. © 2015 John Wiley & Sons, Ltd.

Percutaneous radiofrequency ablation (RFA) enables cauterization of liver cancer in a limited number of sessions without major complications. In contrast to the efficacy of this technique, the size of coagulation necrosis is limited due to increased impedance. D-sorbitol has been used as an irrigating fluid during transurethral resection of the prostate, since it is considered to be a dielectric fluid. In order to determine whether D-sorbitol enhances the effect of RFA, RFA was performed by slowly injecting 3% D-sorbitol near the tip of the RFA needle. The maximum of the total injected volume of D-sorbitol was 20 ml and RFA was terminated if the threshold of impedance was exceeded. RFA and D-sorbitol RFA were performed in 5 different parts of pig livers and dog livers
