현대 사회는 고령층 인구의 확대와 당뇨병 발병률의 증가에 따라 당뇨에 대한 인식이 커지고 있다. 특히 당뇨 환자는 갑작스런 저혈당 쇼크가 발생할 수 있으므로 주기적으로 혈당을 측정하는 것이 중요하다. 하지만 자가 혈당측정기는 휴대의 불편함과 값 관리의 어려움을 동반하고 있다. 이를 해결하기 위해 혈당측정시스템은 센서 형태나 스마트기기와 연동이 되는 형태로 연구되고 있으나 상용화 되지 못하고 있다. 본 논문에서 제안하는 시스템은 이를 해결할 수 있는 혈당측정 기능이 포함된 스마트밴드이다. 사용자는 앱에서 식전/식후와 같은 혈당을 측정해야 하는 일정을 입력하면 밴드에서 알람을 받을 수 있다. 밴드에서는 언제든지 혈당 측정이 가능하며, 측정값은 식전/식후와 같은 값과 날짜와 시간을 포함하여 앱으로 전송되어 관리된다. 이를 통해 사용자의 건강관리, 진단 및 예방에 도움을 준다. 본 시스템은 의료기기인증이 된 2개의 제품과 성능평가를 진행하여 혈당 측정값도 더 정확함을 확인했다.

A 14 kg, 9-year-old, spayed female, Cocker Spaniel was presented to the Veterinary Medical Teaching Hospital of Seoul National University with a history of head tilt and circling. Otitis externa and media were diagnosed by computerized tomography, and total ear canal ablation was performed. In preanesthetic evaluation, systemic hypertension and second-degree atrioventricular block were observed, but there was no regurgitation through the heart valves. Systemic hypertension was managed with amlodipine (0.1 mg/kg, PO, BID) for the anesthesia. The dog was premedicated with cefazolin (22 mg/kg, IV) and midazolam (0.2 mg/kg, IV). Anesthesia was induced with alfaxalone (2 mg/kg, IV) and maintained with isoflurane and 100% oxygen following intubation. During surgery, vital signs (heart rate, respiratory rate, blood pressure, end tidal carbon dioxide partial pressure and body temperature) were maintained within normal ranges, but bradycardia was observed and corrected with glycopyrrolate (5 ug/kg IV, twice). During subcuticular suture, electrohemostasis was applied at the incision line, which was close to the trigeminal nerve. In no time at all, heart rate dramatically decreased from 110 to 60 beats per minute. No additional treatment was done because mean blood pressure was maintained above 70 mmHg. The heart rate recovered according to the decrease of end tidal isoflurane concentration and there were no complications associated with the anesthesia and surgery. Sudden bradycardia after electrical stimulation around the trigeminal nerve was considered as trigeminocardiac reflex (TCR). It is recommended to be careful of bradycardia from TCR when electrocautery is used in the craniofacial area during surgery.

Objectives : This study was performed to approach of properties-flavours theory and the study of morphological standard in CORNI FRUCTUS. Methods : The properties-flavours theory were attempted with bibliographic method and various climate-information. The external-internal morphological standards were determined by using stereoscope and butanol series. Results and conclusion : 1. The significant analysis for the corni fructus as the properties-flavours theory, is a follow-up survey of the effect written in the official oriental medicine book. 2. The other analytic methods according to the gathering time, processing or storing system or especially nature or growth environment(altitude, temperature,. the mean moisture, and the agronomical survey) by way of the explanation of properties-flavours theory appears so many insufficiency at the many cases. 3. The external and internal characteristics according to the shape of original plant or herbal states, entirely correspond to all the literature on this subject. 4. According to the place of production, there are some different points. (l) In the external shapes, it is reasonable that if we make the basic standard of classification by the sharpness of color, the existence of gloss and the size of products. In the case of the Korean products, it shows bright and glossy color totally, but in the case of North Korea products, it shows black and lackluster. And in the case of the foreign products, it has softer body than Korea one and shows white color on the surface. (2) In the internal shapes, the Korea products has a thicker cuticle layer than the foreign one, and has fewer ca-oxalate in the parenchyma cell.

Electrocardiogram (ECG) is a widely used method to diagnose electrical activity of heart. Although it is a reliable and easy method, ECG could be interfered by electrical signals. One of the interfering signals is electromyogram (EMG) that is caused by muscle contraction in any parts of the body except heart. To avoid the EMG noise, an examinee is advised to be relaxed on supine position while measuring ECG. Sometimes, patients who can't put their arms and legs down on bed due to some reasons such as cast on arms or legs necessarily have the EMG noise. But detailed information about how much of the noise could be induced by positional change of arms and legs has not been reported. Here we examined the noise by analyzing ECG data from 14 candidates, 7 males and 7 females. The ECG data was obtained using the standard 12 lead ECG. EMG noise was induced by raising arms and legs at $90^{\circ}$, $60^{\circ}$ or $30^{\circ}$. Because arms are located close to the heart, noise by the raised arms was analyzed toward left or right arm separately. All of the examinees showed similar pattern of the EMG noise. EMG noise by positional change of left or right arm was clearly monitored in different limb leads. Change of leg positions induced the noise that was monitored in aVF of augmented leads and II and III of limb leads. There was a difference in degree of the noise between male and female examinees. In addition to the EMG noise, decrease of PR interval was monitored in particular positional changes, which was prominent in male examinees. These results will enlarge fundamental understanding about EMG noise in ECG.

넓은 통과대역과 좁은 천이대역폭을 갖는 디지털 필터는 이동통신 장비의 CODEC이나 의료장비등에 사용된다. 이러한 주파수 특성을 갖는 디지털 필터는 다른 주파수 특성의 디지털 필터에 비해 계수 및 내부신호의 양자화 영향을 크게 받기 때문에 긴 워드 길이가 요구되며 이로 인해 칩의 면적 및 소모 전력이 증가한다. 본 논문에서는 이러한 주파수 특성을 갖는 디지털 필터의 저전력 구현을 위하여 CPL (Complementary Pass-Transistor Logic), 격자 웨이브 디지털 필터와 수정된 DIFIR (Decomposed & Interpolated FIR) 알고리듬을 이용한 설계 방법을 제시한다. CPL에서의 단락전류 성분을 줄이기 위하여 PMOS 몸체효과, PMOS latch 및 weak PMOS를 이용하는 3가지 방법에 대해 시뮬레이션을 통하여 비교한 결과 전파지연, 에너지 소모 및 잡음여유 면에서 PMOS latch를 사용하는 방법이 가장 유리하였다. 통찰력을 가지고 CPL 회로를 최적화하기 위해 CPL 기본구조에 대해 시뮬레이션 결과로부터 전파지연과 에너지 소모에 대한 경험식을 유도하여 트랜지스터의 크기를 정하는데 적용하였다. 또한 필터계수를 CSD (Canonic Signed Digit)로 변환하고 계수 양자화 프로그램을 이용하여 필터계수의 non-zero 비트수를 최소화시켜 곱셈기를 효율적으로 구현하였다. 알고리듬 측면에서 하드웨어 비용을 최소화하기 위해 수정된 DIFIR 알고리듬을 사용하였다. 시뮬레이션 결과 제안된 방법의 전력 소모가 기존 방법보다 38% 정도 감소되었다.

1. Objectives: We aimed to propose a sub-classification system for the Taeeumin symptomatology by examining the Taeeumin pathology and symptomatology descriptions appearing in "Donguisusebowon". 2. Methods: The Gabo Edition and the Sinchuk Edition (the upgraded and revised edition) of "Donguisusebowon" were reviewed and examined for relevant information on the Taeeum pathology and symptomatology. 3. Results and Conclusions: 1) In the Taeeumin symptomatology, the Exterior disease develops from the basic pathology of Esophagus-Cold and the Interior disease from that of Liver-Heat, eventually progressing to damage of the expirational and dispersive energy of the Lung Sector, the Prime Core Organ or the excessively small organ of the Taeeum constitutional type. The resulting pathology can be broadly defined as the "Lung-Dryness symptomatology". 2) The case reports introduced in the Exterior disease section, including the Zhang Zhongjing Mahuang-tang treatment, Prolonged-affliction disease treatment, and Exterior disease Pestilential disease treatment, share several points in common. They all arise from the pathology of "weakness in the Lung sector and deficiency in the Exterior sector", and they can all be assigned to the same symptomatological division that presents with systemic heat and cold intolerance; this symptomatology can be defined as the "Esophagus-Cold symptomatology", the milder subdivision of the exterior symptomatology. 3) The body of text appearing in the last part of the Interior disease section commonly referred to as the "Taeeumin Conspectus" is in fact not a conspectus when its contents are actually examined. Instead, it can be understood from its pathological and symptomatological descriptions that the passage is explaining the more severe subdivision of the exterior symptomatology that has progressed from Esophagus-Cold to a pathology characterized by damaged expirational and dipersive energy of the Lung Sector. 4) The relocation of the "dry-related pathology" indicates a change in perspective regarding the "Dry-related symptomatology", which caused the rearrangement of the Interior disease into divisions of Liver-Heat symptomatology that is characterized by fulminant heat pathology and Dry-Heat symptomatology that is also accompanied by Lung-Dryness. 5) The Interior disease Yin-Blood Consumptive symptomatology should be included in the Dry-Heat symptomatology in the pathological scheme. 6) Based on the above, the subdivisions of the Taeeumin symptomatology should be arranged as "Esophagus-Cold symptomatology" and "Lung-Dry-Cold symptomatology" in the Exterior disease and "Liver-Heat symptomatology" and "Dry-Heat symptomatology" in the Interior disease.
