In medical institutions, it is an issue how quantitative sensory testing (QST) is conducted. Authors have been studied to develop the complex typed inspection device for inspecting the sense of vibration and sense of temperature. Stimulus probe for sense of temperature is configured by a Peltier element. Using the prototype of the stimulus probe, we tested for how patients suspected of having a sensory impairment and healthy subjects felt the stimulus. Comparing that patients and healthy subjects, the proportion of that patients could detect correctly was revealed lower than healthy subjects at each temperature. To generate the same stimulus as a tuning fork for using in the examination of sense of vibration, we have devised a vibration stimulus probe that combines an electromagnetic coil and an elastic material. As results of experiments, the prototype device was able to generate a vibration force of nearly equal to the tuning fork.
In recent years, Japanese has been faced with an increasingly aging society, which has resulted in problems such as a lack of care workers and an increasing number of elderly people living alone. These problems are anticipated getting more serious by cabinet office of Japan. It will be hard for elderly people to receive care. Here, we propose a system for confirmation of the safety of elderly people. In this system, we can infer the safety of elder from operating home electric appliances by using the proposed system with a magnetic resistance sensor. When the home electric appliance is operating, a magnetic field is produced around its supply cable by the current passing through the supply cable. The magnetic resistance sensor detects the magnetic field. Herewith, the proposed system detects operating the home electric appliances and monitors the operations. From the operational status of the home electric appliances, we can confirm the safety of elderly people.
The B-spline curve is often used as a method to draw an arbitrary curve like a handwritten figure. However, it is difficult to operate the position of the control points for the faithful drawing. In addition, to arrange the control points by hand, a lot of experiences are needed. In this study, the concept of S-System, which is one of the extended models of Genetic Programming, is utilized for the generation of the B-spline curve. The purpose in this study is to reproduce an arbitrary curve faithfully by using a less control points and to arrange the control points automatically. The detailed procedure is as follows. The several points on the curve are selected and it is regarded as the chromosome. The crossover is practiced between two chromosomes. For the validity of this strategy, B-spline curve similar to handwritten curve is reproduced by using a less control points, and they are arranged automatically.
The cancer cells are known that they have a difference of their growth rate and effect of the medicine even if they are taken from the same site. We can check the progress in the morphological feature extraction using a microscope, but we can’t yet to classify the inherent differences. In this study, we proposed a system that allows for the difficult classification by visual analysis. The method is that first we created a database using a laser scanning cytometer (LSC) from protein information on the cancer cells, and learn the relation between the cancer cells and protein using a support vector machine (SVM). We performed the performance evaluation of recognition system by simulate the unknown cancer cells, and confirmed that there were two kinds of cancer cells that have high recognition rate and slightly inferior rate. Therefore, we report about the experimental verification to investigate that the problem of recognition accuracy.
