  • Heart rate variability (HRV) in electrocardiogram (ECG) is an important index for understanding the health status of heart and the autonomic nervous system. Most HRV analysis approaches are based on the proper heart rate (HR) data. Estimation of heart rate is thus a key process in the HRV study. In this paper, we report an innovative method to estimate the heart rate. This method is mainly based on the concept of periodicity transform (PT) and instantaneous period (IP) estimate. The method presented is accordingly called the "PT-IP method." It does not require ECG R-wave detection and thus possesses robust noise-immune capability. While the noise contamination, ECG time-varying morphology, and subjects' physiological variations make the R-wave detection a difficult task, this method can help us effectively estimate HR for medical research and clinical diagnosis. The results of estimating HR from empirical ECG data verify the efficacy and reliability of the proposed method.

  • The purpose of this study was to analyse on the clothing practice of automaker's uniform and to investigate the relationship between wearing sense of worker's uniform and overall comfort according to working environment and working types. The data were collected from 184 automakers using questionnaire and interview of a officer for uniform management. Working environment was relatively comfortable, but the worker in special working area needed to control the working environment and adopted the protective equipment. The dissatisfaction of clothing practice of uniform was shown high in design and material. The order of preference in the color was blue, navy, blue, gray, green. In case of taking care of uniform, sewing durability and shape stability were poor in comparison with washing easiness. The correlation between overall comfort and wearing sense of uniform as sense of wearing and taking off, texture and movement function, was relatively high, but it appeared the low correlation in physiological comfort.

  • The two major classes of magnetic resonance (MR) contrast agents are paramagnetic contrast agents, usually based on chelates of gadolinium generating T1 positive signal enhancement, and super-paramagnetic contrast agents that use mono- or polycrystalline iron oxide to generate strong T2 negative contrast in MR images. These paramagnetic or super-paramagnetic complexes are used to develop new contrast agents that can target the specific molecular marker of the cells or tan be activated to report on the physiological status or metabolic activity of biological systems. In molecular imaging science, MR imaging has emerged as a leading technique because it provides high-resolution three-dimension maps of the living subject. The future of molecular MR imaging is promising as advancements in hardware, contrast agents, and image acquisition methods coalesce to bring high resolution in vivo imaging to the biochemical sciences and to patient care.

  • Modern Objectification of Pulse Diagnosis, One of the Four Diagnosis Method of Oriental Medicine, is necessarily project to improving Oriental medical clinic status and quality by standardization of diagnosis database. At that, accurate measurement equipment or devices(sensor, system and instruments, etc,) to exactly detect MacSang(脈診 : the parameter and subject of pulse diagnosis) have not developed yet. Existing Pulse diagnosis devices are not satisfy clinical needs and medical equipments quality. We study for pulse diagnosis system, that CD is satisfying oriental medical clinic needs, is ensuring accuracy and reappearance to support in clinical diagnosis and treatment, is guaranteeing the quality of medical equipments. theoretical base and convenience.

  • It was aimed to report a case of both anterior cerebral artery territory infarction patient improved by korean medical treatment. The patient was diagnosed by brain magnetic resonance imaging(MRI) and magnetic resonance angiography(MRA). The symptoms were quadriplegia, urinary frequency, urinary incontinence and abulia. I applied herbal medicine, acupuncture, moxibustion, pharmacopuncture, cupping and physical exercise therapy. As a result of them, the symptoms of the patient were improved considerably. Status of the patient was evaluated by manaul muscle test(MMT), modified barthel index(MBI) and functional independence measure(FIM) and medical interview. MBI score was changed from 35 to 95 and FIM score was changed from 66 to 115. Therefore this report suggests that korean medical treatment could be effective to the anterior cerebral artery territory infarction.

  • While in some instances, loss of diversity results from acute toxicity (e.g. major pollution incidents), in most cases it results from long-term sub-lethal effects that alter the relative competitive ability and fitness of certain organisms. In such cases the sub-lethal effects will cause a physiological response in the organism that ultimately leads to community level changes. Very sensitive tools are now available to study sub-lethal responses at the molecular level. However, relating such laboratory measurements to ecological effects represents a substantial challenge that can only be met by investigation at all scales (molecular, individual organism and community level) with an appropriate group of organisms. Among the various in vertebrates which can be used as model organisms in such a way, the soil nematode, Caenorhabditis elegans appear to be a promising biological model to diagnose environmental quality. This paper reviews the current status of multilevel biomarkers in environmental toxicology, and C. elegans as promising organisms for this approach.

  • The purpose of this study was to provide basis data for the pattern and material development of the Taekondo uniform by investigating the Taekwondo uniform wearing status of 260 Taekwondo players. The results can be summarized as follows: 1. In the current material of Taekwondo uniform, the problem of physiological comfort was generally dissatisfied in all subjects. And this unsatisfactory trend was founded higher in female player. 2. In the problem of the body fitness of Taekwondo unifrom, the unifitness of upper and lower clothes was founded higher in female player. And both of male and female player represented unfitness more high in lower clothes. So the current size of Taekwondo uniform, especially the size of lower clothes had its problem. 3. The problem of the sports function, the body fitness and easiness of wearing of Taekwondo uniform was generally founded uncomfortable in all subjects. But especially female player, fat type player was founded higher in the phase of discomfort. And accoring to the method of gaining clothes, the case of the slop was founded the highest.

  • A distributed healthcare monitoring system prototype for clinical and trauma patients was developed, using wireless sensor network node. The proposed system aimed to measure various vital physiological health parameters like ECG and body temperature of patients and elderly persons, and transfer his/her health status wirelessly in Ad-hoc network to remote base station which was connected to doctor's PDA/PC or to a hospital's main Server using wireless sensor node. The system also aims to save the cost of healthcare facility for patients and the operating power of the system because sensor network is deployed widely and the distance from sensor to base station was shorter than in general centralized system. The wireless data communication will follow IEEE 802.15.4 frequency communication with ad-hoc routing thus enabling every motes attached to patients, to form a wireless data network to send data to base-station, providing mobility and convenience to the users in home environment.

  • In this study, after we analyzed 44 recent research paper written about obesity treatement, we tried to understand the acupuncture on the obesity treatment of the recent trend. We searched the recent papers with the key word of obesity, obese, and Acupuncture and are limited since 2004 in the search site KISS, KSI. Recently, acupuncture application for obesity treatment were 6 type. Traditional Acupuncture, Auricular Acupuncture, Electro Acupuncture, Herbal Acupuncture, Chi Acupuncture, and Acupoint Catgut Embedding Therapy. Although acupuncture application were effective method to decrease weight and localized fat, they were critical to evaluate to their effectiveness through strict and scientific clinical trials.
