A novel stereolithography method using evanescent light has been proposed as a means to realize 100-nanometer resolution. An in-process measurement system with high accuracy has been introduced to the nanostereolithography apparatus. Specifically, an optical microscopic system was developed to monitor the exposure process and a confocal positioning system was established to improve the longitudinal positioning accuracy in the layer-by-layer process. A high-power objective lens, a tube lens, and a charge coupled device (CCD) were included in the optical microscopic system, whereas a laser, a high-power objective lens, a piezoelectric (PZT) stage, a condenser lens, a pinhole, and a photomultiplier (PMT) made up the confocal microscopic system. Two verification experiments were conducted, and the results indicated that the optical microscopic system had a horizontal resolution of 200 nm and that the confocal positioning system provided a depth resolution of 30.8 nm. These results indicate that nanostereolithography can be successfully performed with this system.

Rheumatoid arthritis and osteoporosis are two common orthopedic diseases. Rheumatoid arthritis is a disease that inflammation occurs in the joint, which always causes the joints are able to move freely. Osteoporosis is a disease that bone mineral content is reduced and risk of fragility fracture increases. As one of the diagnostic methods, medical imaging by photographed CR equipment has been widely accepted. However, some problems such as mass screening data sets and mis-diagnosis are still remained in visual screening. In order to solve these problems and reduce the burden to physicians, needs of an automatic diagnosis system capable of performing quantitative analysis is anticipated. In this paper, we carry out the development of a segmentation method of phalanges regions from CR images of the hand to perform a quantitative evaluation of rheumatoid arthritis and osteoporosis. The proposed method is carried out crude segmentation of phalanges regions from CR images of the hand, and extracts the detailed phalanges regions by Multi Scale Gradient Vector Flow Snakes (MSGVF) method. In our study, we performed Snakes algorithm to give an initial control points on MSGVF algorithm. We applied our method on three pairs of CR temporal images of phalanges regions, which are called as the previous images and the current images. We got the segmentation results of 5.95 [%] of false-positive rate and 92.9 [%] of true-positive rate.

Purpose Japan is one of the most natural disaster-prone countries in the world. In the case of a natural disaster or mass casualty incident, a large number of injured people are likely to go to hospitals, which need to provide more services at such times. Thus, it is necessary for various bodies - such as hospitals, municipalities, medical associations, pharmaceutical associations, and trade associations - to collaborate. For example, coordination among multiple hospitals is important when transporting patients to another hospital if they cannot be examined at the first one. There is a pressing need to establish an Area Disaster Resilience Management System for Healthcare (ADRMS-H) to increase medical resilience. In order to develop an ADRMS-H and ensure that continuous healthcare is provided during calamities, it is necessary to clarify the functions (which we have already explained) and coordination that organizations must perform. Since medical care needs change by the hour during disasters, so do the functions that guarantee ongoing healthcare. This study aims to create a matrix of functions ensuring continued healthcare services in a disaster and relevant organizations to understand each one``s role and how they relate to each other. Methodology/Approach We used the case of Kawaguchi city in Saitama Prefecture, Japan as an example to illustrate related organizations needed to fulfill the functions for ensuring continued healthcare services. Next, we created a matrix of the functions and organizations. Findings This study identified related organizations such as municipalities, hospitals, medical associations, and trade associations in Kawaguchi city. Since functions for ensuring ongoing health care change by the hour, so do the organizations, whose transformations we analyzed by the hour. Value The results of this paper can help people understand how related organizations work together during disasters; in light of this, it will be possible to develop a model for an ADRMS-H in terms of coordination among organizations.
