Conceived to acquire personal information for an electronic medical record, the clinical interview contains probing questions. The number and type of inquiries are assumed to fulfill medical protocols, and therefore are deemed essential for treatment - but the rate can and should be controlled. High rates of inquiry merely intimidate the patient and affect replies. The purpose of this paper is to mathematically formulate permissible rates of clinical interviews held during telehomecare virtual visits and designed to avoid patient anxiety. Mental stress is derived as a function of the weight of importance assigned by the patient, virtual visit duration, and the rate of questioning in the direction of greater sensitivity. Two operations are of interest: Collecting and recording information by the provider, and maintaining synchrony of questions and answers by the patient. The Lorentz transformation yields the patient’s view of the operational rates. Conservation of information momentum is postulated and applied before and after replies are recorded. It is shown that the weight of importance designated by the patient to collecting and recording personal information is driven by a singularity that depends on the rate of questioning. The findings should serve as a guideline in interviewer training programs.

The paper's suggestion is about hereditary facts between family members. Diagnosing patients from the point of patients temporary conditions, and so performing primitive examinations and treatments, can lead not only to frequent wrong diagnoses, and to huge medical expenses and times to the patients, but even to critical situation of patients or taking lives away. As a means to cut these cases down to a minimum, sharing medical treatment information between family members is suggested. This approach makes possible understanding physical constitution and environment between family members, and can result in bringing a faster treatment effect if some family member suffers from a similar disease. This approach, since a participation in a family membership effectuates all of family members, can minimize the membership fees, thus enabling inter-family health care on a home doctor basis.

From 51 monographs of case record in Qing Dynasty, we chose 29 monographs in which tongue diagnosis applied to Warm disease. Then extracted all the case records and got 488 cases from them. In according to the classification of tongue diagnosis in teaching material of TCM diagnosis of higher TCM schools education, we had a statistic analysis on the 488 cases. Results show that the recording rate of tongue coating was highest, 65.16%. From high to low sequentially, the frequency of different fur was yellow fur, white fur and black fur. During $1850{\sim}1911$ of Qing Dynasty, the description of tongue coating changed that the proportion of white fur, yellow fur and compound fur was increased. On the contrary, the proportion of black fur was decreased. The recording rate of the color of tongue was 23.16%, in which the rate of red tongue and crimson tongue were higher. The recording rate of fur character was 37.7%. During $1850{\sim}1911$ of Qing Dynasty, the recording rate of greasy fur was increased to the first. The application of tongue diagnosis involves the warm-heat species of Warm Disease, damp-heat species of Warm Disease and pestilence.

본 논문에서는 스마트폰의 BLE 광고 기술을 이용하여 별도의 BLE 디바이스 및 인프라 구축이 필요 없는 스마트폰을 이용한 전자출결시스템을 제안하였다. 기존의 BLE를 이용한 전자출결시스템은 서비스를 위해서는 BEL 디바이스를 각 강의실마다 부착해야 하며 강의실에 부착된 디바이스를 구분하기 위해서는 별도의 기술이 필요하였다. 또한 항시 동작하기 때문에 서로의 간섭으로 인하여 전자출결이 간혹 오류가 생기기도 하였다. 본 논문에서 제안한 전자출결시스템은 기존의 블루투스 비콘 방식의 전자출결시스템의 단점인 시스템 구축을 위한 비용적인 문제를 해결하고, 이동식 전자출결로서 활용이 가능하여 시간과 장소의 문제점을 해결할 수 있으며 별도의 BLE 디바이스 없이 본인이 사용 중인 스마트폰의 BLE(Bluetooth Low Energy) 광고 기능을 이용하여 전자출결을 위한 인프라 구축이 가능한 장점이 있다.

A workstation for archiving and communication of medical records is developed for clinical use in hospital. In this system, handwritten diagnostic reports, medical recording papers such as ECG and EEG etc., and ultrasound images are stored in optical disks instead of papers. This system improves medical service owing to speedy diagnosis by fast finding the patient's medical chart, and curtails the cost of archiving medical charts economically. If this system can be combined with already developed MPACS, then integrated medical image di- agnosis will be possible.

The present study was primarily carried out to characterize the properties of the spinomesencephalic tract (SMT) neurons that project from the upper cervical spinal segments to the midbrain. It was also investigated whether these neurons received convergent afferent inputs from other sources in addition to cervical inputs. Extracellular single unit recordings were made from neurons antidromically activated by stimulation of midbrain. Recording sites were located in lamina $I{\sim}VIII\;of\;C1{\sim}C3$ segments of spinal cord. Receptive field (RF) and response properties to mechanical stimulation were studied in 71 SMT neurons. Response profiles were classified into six groups: complex (Comp, n=9), wide dynamic range (WDR, n=16), low threshold (LT, n=5), high threshold (HT, n=6), deep/tap (Deep, n=10), and non- responsive (NR, n=25). Distributions of stimulation and recording sites were not significantly different between SMT groups classified upon their locations and/or response profiles. Mean conduction velocity of SMT neurons was $16.7{\pm}1.28\;m/sec$. Conduction velocities of SMTs recorded in superficial dorsal horn (SDH, n=15) were significantly slower than those of SMTs recorded in deep dorsal horn (DDH, n=18), lateral reticulated area (LRA, n=21), and intermediate zone and ventral horn (IZ/VH, n=15). Somatic RFs for SMTs in LRA and IZ/VH were significantly larger than those in SDH and DDH. Five SMT units (4 Comps and 1 HT) had inhibitory somatic RFs. About half (25/46) of SMT units have their RFs over trigeminal dermatome. Excitabilities of 5/12 cells and 9/13 cells were modulated by stimulation of ipsilateral phrenic nerve and vagus nerve, respectively. These results suggest that upper cervical SMT neurons are heterogenous in their function by showing a wide range of variety in location within the spinal gray matter, in response profile, and in convergent afferent input.

Various Endoscope Video System have been introduced and used at wide fields in our country. But this system doesn't have fuction available for recording of Video and Audio data at a time. So many problems were caused by this point, like loose of data accuracy, time and manpower consumption for re-editing prodedure and so on. For solving these problems, we made and modified some systems considering economical and practical aspects and tried to lift up efficiency of clinical usage.

Tri-stimulus values of CIE-XYZ and RGB values obtained by photographic film, CCD camera or scanner depend on the spectral sensitivity of imaging devices and the spectral radiant distribution of the illumination. It is important to record and reproduce the reflectance spectra of the object for true device independent color reproduction and high accurate recording of the scene. In this paper, a method to record the reflection spectra of the object is introduced and its application to spectral endoscopes is presented.

Independent Component Analysis (ICA) is a blind source separation method using unsupervised learning and mutual information theory created in the late eighties and developed in the nineties. It has already succeeded in separating eye movement artifacts from human scalp EEG recording. Several characteristic sleep waves such as sleep spindle, K-complex, and positive occipital sharp transient of sleep (POSTS) can be recorded during sleep EEG recording. They are used as stage determining factors of sleep staging and might be reflections of unknown neural sources during sleep. We applied the ICA method to sleep EEG for sleep waves separation. Eighteen channel scalp longitudinal bipolar montage was used for the EEG recording. With the sampling rate of 256Hz, digital EEG data were converted into 18 by n matrix which was used as a original data matrix X. Independent source matrix U (18 by n) was obtained by independent component analysis method ($U=W{\timex}X$, where W is an 18 by 18 matrix obtained by ICA procedures). ICA was applied to the original EEG containing sleep spindle, K-complex, and POSTS. Among the 18 independent components, those containing characteristic shape of sleep waves could be identified. Each independent component was reconstructed into original montage by the product of inverse matrix of W (inv(W)) and U. The reconstructed EEG might be a separation of sleep waves without other components of original EEG matrix X. This result (might) demonstrates that characteristic sleep waves may be separated from original EEG of unknown mixed neural origins by the Independent Component Analysis (ICA) method.
