소형 영구자석이 부착된 상태에서 요골동맥의 미세한 움직임으로 자기장 변화를 측정하는 홀소자 집게형 맥진기를 개발하였다. 이 맥진기를 통해서 얻은 120명의 임상데이터를 통계적 로지스틱 회귀분석으로 처리하여 허맥과 실맥을 예측하는 알고리즘의 특성을 연구하였다. 요골동맥파의 반사파 시간값과 절흔점 시간값이 허맥과 실맥을 예측할 수 있는 주요인자이였으며, 판별율은 65%이었다. 이로써 한의학적 허맥과 실맥을 예측하고 판별하는 진단지표로 사용할 가능성을 제하였다.

The conventional simulators used the expensive commercial artificial heart with a limited performance, and focused on replicating the heart function. The arterial pressure is the key factor of the cardiovascular disease. The purpose of this study is to develop a simulator focused on the pressure wave. The simulator is composed of a step motor, slider-crank mechanism, piston-cylinder, two check valves, a elastic tube, and two reservoirs. With the changes of design parameters, the functions of the simulator were evaluated. The simulator shows the good agreement of the characteristics of the cardiovascular system.

A wrist wearable cuffless pulsimeter with a portable and small size apparatus using Hall effect is fabricated. The analysis of the pulse wave measured by the testing product of pulsimeter is done to measure the pulse rate and blood pressure. The blood pressure obtained by the puslimeter is compared with the practical values measured by electronic or mercury liquid blood pressure meters. The detail analysis of a pulse wave measured by a wrist wearable cuffless pulsimeter detecting the changes of the magnetic field can be used to develop a new diagnostic algorithm of blood pressure applying for oriental medical apparatus.

Objectives The aim of this study is to contribute to the establishment of the Traditional Korean Medicine (TKM) policies in future, which is through the assessment to predict the realization by diagnostic subjects. Methods First, we evaluated 8 subjects that were deduced by professionals in 1996 regarding whether or not to be realized in 2013. Second, the governmental and private research projects, reports, articles, domestic patents and products were reviewed and investigated. Third, the Subjects in domestic fields of TKM were investigated on the followings: importance, time of realization, domestic Research and Development level, principal agents and methods for the realization, and hindrance factor on the realization. Results Of the 8 forecasting subjects, one subject was realized, two subjects were partly realized and five subjects were unrealized. Thus, their realization rate was 12.5%. The realized subject is the 'Standard naming of the TKM diagnosis'. Conclusion Continuous researches are necessary to realize the TKM subjects and moreover, professionals should predict new feasible TKM subjects, based on this study.

This study aims to provide definitions and standardization for necessities that elderly people can use conveniently and properly in their daily lives and classify necessities for different purposes. First, standard terminologies were defined by reviewing the literature and the relevant laws related to daily necessities for the elders. Secondly, a concept for necessities for the elders was also defined through consultation with experts. Lastly, the elderly's necessities were selected and classified. The elderly's necessities are defined as aids that ordinary elderly people in normal aging process need for the purpose of the convenience of life and aids they wear or use to maintain or improve their health. In this study, the elderly's necessities are divided into three categories: necessities of health, necessities of Oriental medical aids and necessities of daily living. Each category is further classified as follows: Necessities of health include aids for personal medical treatment, aids for personal care and protection and aids for recreation. Necessities of Oriental medical aids include aids for personal medical treatment, aids for personal care and protection and others. Necessities of daily living include aids for personal care and protection, aids for personal mobility, aids for housekeeping, furnishings, aids for communication, information and signalling, aids for handling products and goods and aids for recreation. The classification of the elderly's necessities in this study can be used as basic information for further studies of demand for necessities for the elderly. The results will lay the foundation for a standardization system for the elderly's necessities and the development of silver industry.

A few studies have shown that the function of fusiform face area is selectively involved in the perception of faces including a race difference. We investigated the neural substrates of the face-selective region called fusiform face area In the ventral occipital-temporal cortex and same-race memory superiority In the fusiform face area by the event-related fMRI. In our fMRI study, twelve healthy subjects (Oriental-Korean) performed the implicit distinction of the race while they consciously made familiar-judgments, regardless of whether they considered a face as Oriental-Korean or European-American. In the race distinction as an implicit task, the fusiform face areas (FFA) and the right parahippocampal gyrus had a greater response to the presentation of Oriental-Korean than European-American faces, but in the consciously race distinction between Oriental-Korean and European-American faces, any significant difference in the FFA was not observed. These results suggest that different activation in the fusiform regions and right parahippocampal gyrus resulting from same-race memory superiority could be implicitly taken place by the physiological processes of face recognition.

Objectives The aim of this review is to analyze the study tendency in papers related with ankle sprain which are published in Korea. Methods I searched the OASIS and checked relevant Korean journals. I classified the papers by field of study, publish date, main treatment, evaluation methods and analysed the study tendency. Results 1. There are 9 case studies, 4 comparative effectiveness studies, 11 controlled studies. 2. The paper was published almost every year for more than one. 3. Treatment tool such as acupuncture, pharmacopuncture, acupotomy, heating-conduction acupuncture, etc. was used. 4. The most commonly used evaluation method is VAS (Visual Analog Scale) and AHS (Ankle-Hindfoot scale). Conclusions These results suggest that Korean medical treatment on the ankle sprain can be useful as cure medicine, but there are not sufficient evidence based papers, so there should be further studies.

In Korean medicine, tongue diagnosis is one of the important diagnostic methods for diagnosing abnormalities in the body. Representative features that are used in the tongue diagnosis include color, shape, texture, cracks, and tooth marks. When diagnosing a patient through these features, the diagnosis criteria may be different for each oriental medical doctor, and even the same person may have different diagnosis results depending on time and work environment. In order to overcome this problem, recent studies to automate and standardize tongue diagnosis using machine learning are continuing and the basic process of such a machine learning-based tongue diagnosis system is tongue segmentation. In this paper, image data is augmented based on the main tongue features, and backbones of various famous deep learning architecture models are used for automatic tongue segmentation. The experimental results show that the proposed augmentation technique improves the accuracy of tongue segmentation, and that automatic tongue segmentation can be performed with a high accuracy of 99.12%.

We investigated the activity and stability of alcohol dehydrogenase from horse liver (HLADH) under the electric stimulation. The activity and stability of alcohol dehydrogenase depended on electric output voltaqe, stimulation time, pulse duration and pulse interval, and temperature. HLADH retained about 23% of its activity in buffer but 78% in 10% trehalose solution under electric stimulation with 10V, 10min, The stabilizing of enzymes against electric stimulation by stabilizing additives showed a great potential use of enzymes in biotechnology and medical engineering fields.

의료정보의 양과 질적인 측면에서 현대의학의 발전에 힘입어 정보기술을 접목한 의료 분야는 매우 빠르게 확장되고 있다. 그러나 서양의학에 비하여 한의학의 의료정보 활용은 상대적으로 적은게 사실이다. 이에 본 연구에서는 한의학 관점에서 논의되고 있는 의료정보의 획득을 위한 인터페이스 개발에 관한 연구이다. 이를 위해 한의학 의료정보를 획득할 수 있는 웹기반 인터페이스를 설계하고 이에 대한 구성요소에 대해 살펴보고자 한다. 본 결과를 통해 한의학의 IT를 접목한 근육 통증의 의료정보 표준화에 기여할 수 있을 뿐만 아니라, 기술을 통한 편리성을 추구할 수 있을 것으로 기대된다.
