beta-thalassemia, an anemic genetic disorder, remains a significant global health issue, especially in the era of globalization where healthcare, economics, and education are more tightly interconnected. Although previous studies focused on the medical aspect of beta-thalassemia and the affects of consanguineous marriages, we investigated what affects the socio-economic geography of beta-thalassemia...
An exoskeleton robot is an external structural mechanism with joints and links corresponding to those of the human body. When it is worn, it transmits torques from actuators through rigid exoskeletal links to the human joints. We have been developing exoskeleton robots for assisting the motions of physically weak persons such as elderly or disabled in daily life. In this paper, we propose an electromyogram...
Over the last two decades, mathematical modeling has become a popular tool in study of blood coagulation. This paper describes the coagulation pathway and presents a mathematical model for the generation of blood clot in human vasculature. Parameters of interest in this study include procoagulants and anticoagulants whose activity may be enhanced by various activator enzymes. The process of human...
In this paper, a method of estimating both the position and the rotation angle of an object on a measurement stage was proposed. The system utilizes the radio communication technology and the directivity of an antenna. As the preliminary study, an experimental system that employs RFID technology was developed. Two RFID tags are used for estimating the location of one target object. The experimental...
In this study we have developed a wireless biosignal monitoring device. This device consists of a chip micro processing unit, a three axis acceleration sensor, an ECG amplifier and a wireless serial communication module. This device was set on subject's waist near the center of gravity and was evaluated in filed exercises. As a result it was proved that real time remote monitoring of these biosignals...
This paper proposes a layered architecture for medical information exchanges using internet mail protocols. This architecture realizes smooth and flexible communication between different systems and equipments. In medical fields, every system must pay attention to much security measures for medical information exchange via public network. However, there are innumerable medical information systems,...
In this paper, a virtual breast plastic surgery planning method is proposed, which reconstructs the breast after excision for certain diseases such as cancer. In order to achieve a rational result, we calculate shape, area, volume and depth of the skin and muscle for the reconstruction, based on the other healthy breast. The steps are as follows: 1) input breast's MRI data of patient; 2) get the healthy...
Without increased effort and new initiatives, the total number of road traffic deaths and injuries worldwide could rise by some 65 percent between 2000 and 2020, while deaths in low and middle income countries are expected to increase by 80 percent. Hence prevention is the best remedy for this global public health problem. For the effective prevention of road traffic injuries, accurate information...
This paper addresses the functionality of care devices and telecare applications in terms of agent interactions. It focuses on the kind of interactions involved between the agents, and how can agents determine or find other agents (or their functionality) in a service-oriented telecare environment. It explores the service-oriented architecture (SOA) together with the agent paradigm as a mechanism...
This paper presents a construction of a computer assisted system in dental implantology. Preoperative planning and surgical navigation are two main sub-systems in our proposed system. In the preoperative planning subsystem, we provide different kinds of views to the surgeons based on CT data scanned for a specific patient. And the surgical navigation subsystem uses an infra-red light based navigation...
Cancer is caused by a variety of factors whose study requires a large amount of data. Compiling these data is an expensive and time-consuming task which can be carried out in a better way with the support of Information and Communication Technologies (ICT). However, most epidemiologic studies take place without this support of informatics or with basic tools that are developed by unqualified professionals...
The aim of this paper is to find a relation between HRV parameters of ECG and stressful driving situation in the real road through various tests. First, we gave a stress to the subject by increasing the driving speed using driving simulator in the laboratory. Second, the subject drove the vehicle on the real road. Through let him drove in the busy narrow street, we evoked stress. ECG and PPG signal...
The pulmonary function test by spirometer is generally conducted. The test subject, especially child, woman and older person, feels uncomfortable as the mouthpiece and nasal plug must be attached to the face of them. We have studied the nonrestraint pulmonary function test using the dot matrix pattern projection in order to decrease the burden to the examinee. In our proposed system, the pattern light...
Measurements of subcutaneous fat thickness provide valuable information regarding human health. In previous studies, subcutaneous fat thickness was estimated by bioelectrical impedance; however, this method required sophisticated equipment and analysis. The objective of this study was to develop a simple method to determine subcutaneous fat thickness using apparent resistivity. A single-frequency...
The number of people who have mental health problems, such as depressive disorders, is increasing, but many patients do not take suitable medical treatment due to a lack of clear subjective symptoms. Mental disorders may manifest themselves in term of measurable physiological signals. Using a wearable sensor, we measured heat flux, skin temperature and GSR in healthy people and patients with depressive...
Female breast cancer is the major cause of death in occidental countries. Efforts in computer vision have been made in order to help improving the diagnostic accuracy by radiologists. We propose a methodology to distinguish Mass and Non-Mass tissues on mammograms. It is based on the computation of geostatistical measures (Moran's Index and Geary's Coefficient) over a multiresolution image representation...
In this paper, a handle-electrode system is proposed for obtaining heart-rate of the user during exercising of a treadmill. The system was designed to be measurable the user's heart-rate by only gripping the parallel bar. Three electrodes that made from conductive cloth were adhered to the handle. A method detecting heart-rate from obtained electrocardiogram was also proposed. To assess the applicability...
Due to the recent active research activities in the area of wireless sensor networks (WSN), the development and realization of a light-weighted, low-cost and wireless electrocardiogram (ECG) monitor has become feasible. In this paper, we propose an ECG monitor design based on a commercially available WSN device. The device utilizes 868 MHz ISM license free frequency band and operates on TinyOS operating...
In aging societies such as Japan's, the number of elderly person living alone increases. Since the incidence of disease and injury increases with aging, remotely located family members become anxious about the safety of their elderly parent. The elderly parent is conversely eager for information about the remotely located family. To improve smooth communication between the elderly parent and the remotely...
Developing properly information technology in order to overcome the lack of manpower will be one of main issue in a developed country. The numerous vital signals and image data which were archived by the devices and were modified by information technology would support physician or computer aided diagnosis (CAD) system for diagnosis. Therefore, in order to avoid erroneous identification, the encoded...
