A Method of Describing a Self-occlusive Motion - A Reverse Motion History Image

This paper proposes a new method of describing a self-occlusive human motion, particularly in the depth direction, which has been considered little in the motion/action recognition studies to date in spite of its importance in our daily life. A Motion History Image (MHI) is a well-known method of describing a motion by a single gray value image, but it suffers from a self-occlusion problem in which present motion overwrites past motion. To solve this difficulty, a Reverse description MHI (RMHI) is proposed in the paper. RMHI and the original MHI are both employed for motion representation in the proposed method; the former for approach motion, whereas the latter for leave motion. In the experiment on motion recognition, motions are described by RMHI or MHI according to motion direction, transformed then to Hu moment vectors, and finally recognized employing the k-nearest neighbor. Experimental results show effectiveness of the RMHI description

Mobile Robot Self Localization based on Multi-Antenna-RFID Reader and IC Tag Textile

This paper presents a self-localization system using multiple RFID reader antennas and High-Frequency RFID-tag textile floor for an indoor autonomous mobile robot. Conventional self-localization systems often use vision sensors and/or laser range finders and an environment model. It is difficult to estimate the exact global location if the environment has number of places that have similar shape boundaries or small number of landmarks to localize. It tends to take a long time to recover the self-localization estimation if it goes wrong at once. Vision sensors work hard in dark lighting condition. Laser range finder often fails to detect distance to a transparent wall. In addition, the self-localization becomes unstable if obstacles occlude landmarks that are important to estimate position of the robot. Door opening and closing condition affects the self- localization performance. Self-localization system based on reading RFID-tags on floor is robust against lighting condition, obstacles, furniture and doors conditions in the environment. Even if the arrangement of the obstacles or furniture in the environment is changed, it is not necessary to update the map for the self-localization. It can localize itself immediately and is free from well-known kidnapped robot problem because the RFID-tags give global po- sition information. Conventional self-localization systems based on reading RFID-tags on floor often use only one RFID reader antenna and have difficulty of orientation estimation. We have developed a self-localization system using multiple RFID reader antennas and High-Frequency RFID-tag textile floor for an indoor autonomous mobile robot. Experimental results show the validity of the proposed methods.2013 IEEE Workshop on Advanced Robotics and its Social Impacts (ARSO) Shibaura Institute of Technology, Tokyo, JAPAN November 7-9, 201

Debridement in Patients with Pressure Ulcers

Debridement is a topical treatment for pressure ulcers based on wound bed preparation. and wound healing is triggered only after removal of the necrotic tissue. There are three types of debridement: surgical, mechanical. and autolytic. Surgical debridement is invasive; however, it promotes the wound healing process. It is mainly performed in hospitals. Autolytic debridement is performed in situations wherein it is not possible to cope with bleeding, such as in homecare settings. Although less invasive, removal of necrotic tissue by autolytic debridement takes a substantial amount of time. Mechanical debridement is performed by physically removing small areas of necrotic tissue from the granulation surface using negative-pressure wound therapy, curettes, or the wet-to-dry technique

Isolation and Structural Determination of the First 8-epi-type Tetrodotoxin Analogs from the Newt, Cynops ensicauda popei, and Comparison of Tetrodotoxin Analogs Profiles of This Newt and the Puffer Fish, Fugu poecilonotus

Identification of new tetrodotoxin (TTX) analogs from TTX-possessing animals might provide insight into its biosynthesis and metabolism. In this study, four new analogs, 8-epi-5,6,11-trideoxyTTX, 4,9-anhydro-8-epi-5,6,11-trideoxyTTX, 1-hydroxy-8-epi-5,6,11-trideoxyTTX, and 1-hydroxy-4,4a-anhydro-8-epi-5,6,11-trideoxyTTX, were isolated from the newt, Cynops ensicauda popei, and their structures were determined using spectroscopic methods. These are the first 8-epi-type analogs of TTX that have been found in a natural source. Furthermore, we examined the composition of the TTX analogs in this newt and in the ovary of the puffer fish, Fugu poecilonotus, using LC/MS. The results indicate that TTX and 11-deoxyTTX were present in both sources. However, 6-epiTTX and 8-epi-type analogs were detected only in the newt, while 5,6,11-trideoxyTTX was a specific and major analog in the puffer fish. Such considerable differences among analog compositions might reflect differences in the biosynthesis or metabolism of TTX between these animals

A autopsy case of biliary fistula to the retroperitoneal space

A seventies age man was admitted complaining of epigastric pain. Computed tomography of the abdomen showed the fluid collection and inflammation in the retroperitoneal space besides pancreas. We suspected acute pancreatitis, and started the treatment by the medications. However, the treatment was not effective. Because we suspected of perforation, we underwent the operation. In the operation, there was a large amount of bile in the retroperitoneal space. We performed intraperitoneal drainage because of uncertain cause. After the operation, he got worse, and died on the ５５th day. The autopsy showed the biliary fistula at right hepatic duct to the retroperitoneal space. The biliary fistula to the retroperitoneal space was very rare case, therefore we must understand the pathological condition due to save the life
