The heart rate is the most important vital sign in diagnosing heart status. The simple method to measure the heart rate in the mobile healthcare device is using the PPG signal. In developing the mobile healthcare device using the PPG signal, the most important issue is the inaccuracy of the measured heart rate because the PPG signal is distorted from the user's motions. To improve the problem, this study proposed the new method that is to estimate the heart rate without an additional sensor in real life. The proposed method in this study is using the histogram filter. In order to evaluate the performance of the proposed method, the study compares its results with the moving average method in motion environment. According to the experimental results, the performance of the proposed method was more than 40% better than the performances of the MAF.

Pre schools with state of the art facilities that would provide not just academic excellence but also ensure the safety and provide efficient healthcare to their pupils relative to Atopic Dermatitis with Asthma is the main objective of this research One of the most promising applications of sensor networks is for human healthcare monitoring. Due to recent technological advances in sensor, low power microelectronics and miniaturization, and wireless networking enable the design and proliferation of this wireless sensor networks capable of autonomously monitoring and controlling environments. Thus, this research presents the utilization of such microelectronic sensor and plots the hardware and software architecture of a wireless sensor network system with real-time pupil monitoring that integrates vital sign sensors, location sensor and allergen sensor. This proposed architecture for wearable sensors can be used as active tags which can track pupil's location within the school's premises, identify possible atopic dermatitis with asthma allergens, it would monitor and generate a health status report of the pupil.

최근 u-헬스 중심으로 건강 건강관리를 위해 수많은 PHD(Personal Healthcare Device)가 개발, 상용화 되고 있다. 하지만 대부분의 기기(PHD)들은 각각의 자체적인 프로토콜을 사용하여 통신을 하고 있기 때문에 타 기기간의 상호호환의 어려움이 있다. 이러한 문제점을 개선하고자 ISO와 IEEE에서는 표준화 프로토콜 IEEE11073-20601을 제정하였다. 본 논문에서는 표준 프로토콜 ISO/IEEE11073-20601을 이용하여, ECG(Electrocardiogram) 신호를 수신한 데이터를 Android OS 기반 태블릿에서 보여주고자 한다.

Main bronchial injury after blunt trauma is very rare in all bronchial injuries and the pathogenesis is variable and not well known in everycases. We report a case of complete transsection of right main bronchus by blunt trauma. This 24-year old patient was transferred from a local hospital with a chest tube. Because of the severe subcutaneous emphysema and tension pneumothorax, we inserted one more chest tube resulting no obvious interval change. With the impression of bronchial injury, we performed an exploratory thoracotomy. We couldn't proceed bronchoscopy in the operation room because of his unstable vital sign. After opening of the chest wall, we could identify completely transsected right main bronchus. We anastomosed the bronchus with 4~0 Vicryl interruptedly. After operation, the patient was recovered without any complication.

We present a case of a colonic involvement associated with necrotizing pancreatitis, with a review of the literature. A 10 year old boy had an appendectomy at the local clinic ten days ago. On admission, he complained nausea, vomiting and severe constipation. His abdomen was distended and he had tenderness on the left abdomen. Laboratory and radiologic studies revealed findings consistent with acute pancreatitis with colonic complication. He was treated conservatively for 30 days but did not improve. On hospital 30th day, abdominal pain developed and his vital sign changed. Abdominal CT suggested ischemic change of the transverse colon. At laparotomy, the left colon showed stenosis. The greatly distended transverse colon was resected and a transverse end colostomy was done. He was discharged at postoperative 45th day with improvement and colostomy closure was performed 8 months later.

From March 1986 to March 1991, 29 patients were operated due to cardiac tamponade at the Department of Thoracic and Cardiovascular Surgery, Masan Koryo General Hospital. Among them, 19cases were traumatic origin and 10 were Non traumatic origin. A] Traumatic cardiac tamponade Out of 19 cases, 12 cases were resulted from penetrating injury and 7 cases from trauma. Average time interval from arrival to operation was 91 minutes[15min.~8.5hr.] in penetrating injury group. On the other hand, average time of in cases of blunt trauma was more than 3hours because of the difficulties in diagnosis. Four deaths occured in 19 cases [mortality rate: 21.1%] 3 in blunt trauma group[42.9%] and 1 in penetrating group[8.3%]. In view of our experience, the prognosis was closely correlated with injury mode, initial vital sign and mental status. There was no close correlation between prognosis and cardiac injury site. B] Non traumatic cardiac tamponade The etiologies were malignancy[4], non-spesific pericarditis[3], tuberculosis[1], pyogenic[1] and cardiomyopathy[1]. All of the cases in which performed tube pericardiostomy were the cases that showed no response to conservative treatment and repeat per-icardiocentesis. There was one posoperative death.

1. Objectives The purpose of this case is to evaluate the effects of Sasang constitutional medical diagnosis and treatment on Soeumin Woolgwang-incurable disease with Vascular dementia. 2. Methods We treated two patients who attacked an acute cerebral infarction with dementia. We prescripted Doksampalmul-tang(獨蔘八物湯) for their physical symptoms. The improvement of their diseases were checked through their sleep, irritability, stool and vital sign. 3. Results After the Sasang constitutional medication of Doksampalmul-tang(獨蔘八物湯) were given, their physical symptoms were improved over all. 4. Conclusions This case-studies show an efficient result of using Sasang constitutional medication in the treatment of vascular dementia.

사람으로부터 나오는 신호는 다양하고 그 데이터의 양도 매우 많다. 이러한 신호는 누구에게나 똑같이 발생하는 것이 아니기 때문에 각각의 사람마다 발생하는 신호를 분석하면 그 사람의 건강을 분석할 수 있는 중요한 자료로서 사용되어질 수 있다. 본 시스템은 인체의 손끝은 장부와 연결되어 손끝의 정보를 활용하면 건강을 진단할 수 있다는 한의학적 진단방법을 활용하여 인체 손끝에서 나오는 맥, 온도, 저항을 반사형 포토센서로 측정하여 이를 분석하고 장부의 허실을 판단하여 건강을 진단하는 시스템이다.

The purpose of this study is to stand assembly the meaning and function of entry space with analysing their social and cultural characteristic. The entry space is the linkable place between inner space and out space, and that is the transition place to be experienced two opposing characteristic. Till now the entry space has not taken effect as symbol needed to the resident and observer, and that has been a tendency to shrink as the minimal sign of entrance. So thus, it is in need of studying the entry space's specific and characterizing structurally as expanded function. For the purpose, this study define newly the meaning, function and composition of entry space in an apartment building, and try to find how to reinforce a resident identity. This study propose justification that the entry space isn't boxing space minimally but enforcing symbol presented clearness of composition and vital character.
