'Mu-acupuncture treatment(繆刺法)' and 'Geo-acupuncture treatment(巨刺法)' are the ways of taking acupuncture points on the sound side of a human body and not on the unsound side of a human body to treat disease, 'Mu-acupuncture treatment(繆刺法)' is applicable to 'Transverse meridian disease(絡脈病)', 'Geo-acupuncture treatment(巨刺法)' is applicable to 'Longitudinal meridian disease(經脈病)'. To diagnose a disease as transverse meridian disease or longitudinal meridian disease depends on 'Feeling pulse at the nine spots of three parts on a body for diagnosis (三部九候診)'. 'Mu-acupuncture treatment(繆刺法)' takes a 'Rak-acupuncture point(絡穴)' under a wrist and a ankle joint. The method of taking it, two ways, are 'Yu(痏)' and 'The treatment getting some blood(出血療法)'. 'Yu(?)' which is similar to 'Quick-getting acupuncture into and out (單刺法)' means the number of times doing acupuncture and is different from 'The treatment getting some blood (出血療法)' which is typically considered as 'Yu(?)'. Meanwhile, judging from the changes of the methods of feeling pulse for diagnosis and the symptoms of a certain disease, though it is a precondition that 'Biased-Gi(邪氣)' stays at 'The Large transverse meridian(大絡)' in 'The theory of Mu-acupuncture treatment(繆刺論)', it is hard to consider the symptoms of 'Transverse meridian disease(絡脈病)' described in 'The theory of Mu-acupuncture treatment(繆刺論)' as the pure symptoms of 'Transverse meridian disease(絡脈病)'.

We developed a cuffless and noninvasive measurement technique of blood pressure using tonometric pressure sensor. With observation that the maximum value of pulse pressure is not obtained at mean arterial pressure(MAP), we have figured out MAP based on the physiological characteristic including the elasticity of wrist tisse. Detecting only one part of the body and using only one device are quite advantageous over other BP measurement techniques. Our technique makes new way for the cuffless BP measurement.

Recently, as the sleep disorder problem of modern people deepens, the interest towards quality of sleep is increasing. To increase the quality of modern people's sleep. This paper has suggested an LED lighting control system according to the sleep stage using PPG sensors of wearable devices. The pulse of the wrist radial artery was measured using a wearable device mounted with PPG sensor, which enables heart rate-measuring, and by using the point that heart rate lowers during stable sleep than non-sleeping, the LED lighting of indoors was controlled, which is the disturbing element when sleeping. For the performance evaluation, a 10-Fold cross analysis was conducted for performance evaluation, and a result of an average accuracy 87.02% was obtained as a result. Therefore, the LED lighting control system according to the sleep stage using a wearable device of this paper is expected to contribute to raise the quality of the user's life.

'On the Morbid Pulse of Abdominal Fullness, Cold Mounting, and Abiding Food' in the Chapter 10 of Synopsis of Golden Chamber that enunciates Abdominal Fullness, Cold Mounting, and Abiding Food is related to the stomach and intestines respectively, and is similar to the region and symptom of disease in the light of both abdominal fullness and symptoms of pain. This chapter was united into one because the formula mentioned in this chapter can be applied to three disease patterns. Abdominal fullness shows the symptoms of distention and unease, but judging from the text as well as a specific formula and symptoms, it follows pain. Accordingly Abdominal fullness dealt with in this chapter is the first consideration and it is a kind of a disease pattern attendant on abdominal pain. Cold Mounting does not mean mounting gi disease but means the abdominal pain. The cause of cold mounting is mainly due to insufficiency of yang gi and oversufficiency of cold evil. And the main symptoms of cold mounting follow the severe pain around the naval and sweating, cold of the extremities, pulse deep and tight. Abiding food is of the same meaning such as damage of food today. Abiding food is now referred to as damage of food. Principles which have set forth in this chapter are put to use of the method of ejection in case that abiding food places in the upper part, precipitation in the lower part. The symptoms of abiding food show that the pulse is slight and slippery and the wrist pulse is both superficial and large and rough in applying the pressure, and the cubit pulse is also slight and superficial as well, and that have diarrhea and have little appetite.

In this study, we developed five mobile units and an integrated system which can manage vital signs from each unit using Bluetooth wireless communication. The five kinds of mobile unit were so designed that each has different function to be applied according to the condition of patient properly. The mobile units can measure ECG signal of single or 12 channel, blood pressure, pulse and SpO2 signal from a patient. Also, to reduce the uncomfortable measurement, several types of units such as belt type, wrist type and necklace type were designed. Our proposed system can integrate and monitor several biological signals from different patient by using Bluetooth wireless communication simultaneously. The developed system was evaluated in the simulated emergent situation and showed the system can monitor 5 patients in maximum according to the data quality. It showed the possibilities that the developed system can be used effectively for emergency situation or in- or out-hospital transport of patient. In future, with the combination of mobile communication technique, a patient who is in emergency situation can be provided with proper first-aid and a doctor can pile information of patient and give better diagnosis and treatments.

산소공급은 신체 요구 중 가장 기본적인 것이다. 호흡은 뇌의 연수(medulla oblongata)에 있는 호흡중추와 폐의 정상적 기능에 의해 조절된다. 즉 폐와 환경 사이의 공기 이동인 외 호흡과 헤모글로빈과 단세포 사이의 세포수준에서의 산소 이동인 내 호흡을 말한다. 성인의 호흡수는 보통 1분에 15-20회이나 연령, 운동, 기온, 심리적 변호, 질병상태, 대기의 산소 함량, 약물 투여 등에 따라 차이가 난다. 호흡측정은 대상자가 쉬고 있을 때 하는 것이 중요하다. 호흡 측정은 측정하고 있다는 사실을 대상자가 모르도록 기술적으로 해야한다. 현재 사용하는 방법은 주의를 끌지 않도록 대상자의 팔목에 손을 댄 채로 맥박을 측정한 바로 직후 계속해서 대상자의 가슴의 움직임을 관찰하면서 호흡을 측정하는 것이다. 본 논문에서 구현하고자 하는 것은 관성의 오차 및 압력의 오차에 영향을 거의 받지 않는, 그리고 반영구적으로 사용이 가능한 초음파 센서를 이용한 임베디드 환경의 호흡 량 측정기이다.

Purphose. This present study examines the effect of brief, intense transcutaneous electrical nerve stimulation(BTENS) on sensory nerve conduction, electrical pain threshold, and two-point discrimination measured at the superficial radial nevre distribution in 20 healthy subjects. Subjects. Twenty volunteercs, (10 females and 10 males(age range : 20-38 years : $mean{\pm}SD\;:\;27.00{\pm}5.12$), only subjects without prior traumatological and pathological were eligible to participated in this study. Methods. Nerve conduction were determined for the right superficial radial nerve. Electrical pain threshold were determined for the right wrist ipsilateral to the site of BTENS. Small disc electrodes were attached to the surface of the skin stradding the end of the radius. Square wave electrical pulses were delivered from an isolated stimulator through a constant current device at a frequency of 2 Hz(5 ms pulse width). Two-point discrimination, measured on the sensory distribution of superficial radial nerve. BTENS was delivered using a Max-SD( Medical design co.) portable battery powered stimulator. A cicular Ag/AgCl electrode in contact with hypertonic saline gel was attached to the lateral(radial side) surface of the forearm. Results. No significant effects were observed between stimulation methods in the prestimulation cycle(multi-way ANOVA repeated measures : distal latency ; F1.14=0.332. amplitude ; F 0.80=0.445, pain threshold ; F0.06=0.940.2 point discrimination ; F1.50=0.236). Highly significant effects were observed time with the pretreatment and 6 posttreatment cycles(p<0.01). Mighty significants differences in nerve conduction and pain threshold were found using un multi-way ANOVA repeated measures among stimulation methods for each cycles(p<0.01). Conclusion and Discussion The authors concludes that both nerve conduction and pain threshold changes are associated with therapy (stimulation) level of BTENS.
