Up to the present, digital replantation patients has appealed different symptoms due to blood circulatory failure. But, the level of blood circulatory failure has been evaluated only by clinical symptoms, or angiography. According to the cases of digit replantation is increasing, then objective evaluation methods of the level of blood circulation failure is needed other than patient's subjective symptoms and complaints. Although angiography, doppler, electromagnetic flowmeter, laser blood flowmeter, mechanical blood flowmeter has been used for the evaluation of the blood circulatory failure, the result was affected by time, place, surrounding temperature, patient's body temperature, and even emotion. Therefore, it is pointed out with lack of availability, feasibility and reproducibility. Thus, we compared digital blood flow of dominant hand to non dominant hand, and replanted fingers to opposite normal fingers from developed photo-plethysmography. The average digital blood flow showed no difference in normal digits each other, but, replanted digits showed average of 53% (9 - 100 %) compare to opposit normal digits. As it measure relative blood flow for circulatory failure of tissue such as fingers and toes more sensitively, reliably. In conclusion, it is expected that photo- plethysmography will be very useful for diagnosis, curative effect, prognosis of blood circulatory failure in digital replantation patient.

Traumatic pseudoaneurysm of the intracavernous internal carotid artery(ICA) is extremely rare, but it is life threatening condition because of massive recurrent epistaxis. Unfortunately, the prompt diagnosis and treatment of this disease are frequently delayed due to its rarity and variable latent period, so this disease is regarded as a challenge to clinicians. Optimal therapy for this diseases demands rapid suspicion for it and is essential in order to give the best functional outcome with minimizing its morbidity and mortality. The authors present a case of male patient with traumatic pseudoaneurysm of intracavernous ICA accompanying severe epistaxis. This patient was a 37-year-old male with unilateral blindness and recurrent massive epistaxis after suffering trauma to head. Computed tomography, MRI and carotid artery angiogram showed pseudoaneurysm of intracavernous ICA with sphenoid bone fracture. The patient was effectively managed with occlusion of the pseudoaneurysmal circulation by endovascular interventional embolization technique utilizing mechanically detachable tungsten coils.

In the Clinical study on 1 Case of Patient with Obstruction of the retinal artery, the results were as follows. 1. Obstruction of the retinal artery is acute disease that vision isdiminished fastly and become a blindness. 2. It belong to the cathegory of Pock Maeng(暴盲) in Oriental Medicine. 3. The causes of Obstruction of the retinal artery were the yin-deficiency of liver and kidney, the stagnation of vital energy and blood stasis, the abundance of phlegm-heat, the yang-deficiency of spleen and kidney, the yin-deficiency of spleen and kidney, the nonfastness of primordial energy etc. 4. We could get the effective result by providing the patient with Jinkansikpung-tang-gami(鎭肝熄風湯加味) in the acute period 5. In Acupuncture treament and other treament, Electro-acupuncture theraphy ana Lodestone theraphy were useo for neurologic stimulation, Body acupuncture and Auricula-acupuncture were used for promoting the circulation of vital energy and blood.

Purpose: The aim of this study was to provide basic data to improve the survival rate of pre-hospital cardiac arrest patients. This study suggests a more effective method of performing effective chest compressions for a cardiac arrest patient in a moving ambulance. Methods: To compare the differences between gender and license (qualification), SPSS 18.0 (Windows) was used. Independent and paired t-tests were used for differences between before and after wearing a rescuer's belt. Results: The success rate of chest compressions according to gender was higher in males ($68{\pm}21.91%$) than in females ($25.04{\pm}16.88%$). There was no difference according to license ($44.70{\pm}26.63$ for paramedic, $45.05{\pm}19.25$ for nurse). However, the depth (mm) and the success rate (%) were improved during the evaluation of chest compressions when wearing the rescuer's belt (depth: $46.95{\pm}6.49$ vs. $49.55{\pm}6.05$, success rate: $44.80{\pm}24.66$ vs. $57.39{\pm}26.823$). Conclusion: Wearing a rescuer's belt in an ambulance during patient transport can result in deeper and more accurate chest compressions; therefore, it is expected to be effective in recovering the circulation of patient with cardiac arrest.

Purpose: This study examines construction core plans for the users of vertical-typed general hospitals to effectivly use the flow line. Methods: The study sampled representative 9 hospitals, calculated the depth value through Convex Map of Space Syntax and Justified Graph according to the determination of form of construction cire, and analyzed its functional connectivity. Results: The analysis of the connectivity between operation core part and emergency part of core space with high importance in the hospitals showed that the types of hospital and hospital have the lowest depth value in the spatial phase diagram, where central treatment part and outpatient part are arranged well vertically. Elevators for patients at these hospitals are close to operation and emergency parts actually separated from the elevators for passengers. For shortening of flow line of patients and private movement environment, however, it is desirable to arrange the elevators for patients to be adjacent to the operation parts and to arrange the emergent patient entrances more effectively to separate them from the flow line of visitors and guardians. Implications: Consideration should be taken into account for the effective flow line design. This study hopefully may serve as a stepping stone for the standard design of horizontal/vertical flow line.

Cardiac arrest is owing to the failure of the heart that makes the blood circulation stop. Arrested blood circulation prevents the supply of the oxygen and the glucose and it results the loss of consciousness and, finally, brain death. Many public institution installed the AED for emergency treatment, but, it is not efficient when the patient is alone. In this paper, we made multiplexed wearable device for cardiac arrest detection. With this device, we measure the individual's electrocardiography, heart sound and motion. If the cardiac arrest is detected, the device make a warning horn and transmit the signal for defibrillation. We obtain 98.33% of ECG data, 94.5% of PCG data and 98.38% of IMU data accuracy for each evaluation and 93.33% accuracy for integrated evaluation.

심박동기는 동기능 부전 증후군에서부터 완전 방실차단까지 서맥의 치료에 가장 보편적으로 사용되는 중재적 치료다. 일반적으로 경정맥을 통한 심내 심박동기를 많이 사용하고 있으나 감염 및 혈전증, 박동기의 기능부전, 부정맥, 심근천공, 삼첨판 폐쇄부전증 등의 합병증이 발생할 수 있다. 심박동기의 감염은 전신감염으로 이행되어 환자 상태가 빠르게 악화될 수 있으므로 감염으로 의심되면 제거하는 것이 원칙이다. 추나 올가미 등을 이용한 방법등 비수술적인 방법외에도 체외순환을 이용한 적극적인 제거도 환자 상태에 따라 고려해야 할 것이다. 감염된 심박동기를 체외순환을 이용하여 제거한 두 개의 증례를 보고하는 바이다.

Recently, Influenza(AI, PI) patients have been increasing rapidly. But, there is a lack of isolation hospitals. In particular, according to increase the rate of patients with airborne infection, in order to prevent the spread of pathogens, design of layout plan and air conditioning system of isolation hospitals becomes more important to maintain patient's room as negative pressure. In this study, the spread of pathogens are analyzed as room differential pressure, moving time of medical staff and patients, and moving way in isolation hospitals by multizone simulation; CONTAM 2.4. Through the analysis, the ways to improve isolation hospital considered at the design step are reached to prevent the spread of pathogens effectively. Also, it verifies that HVAC system for isolation hospital is suitably designed as standard.

The path and visibility of nurses in general hospital wards have been treated as architectural planning factors. However, the analysis approach of existing studies shows limitations that only fixed physical elements are considered without considering the behavior of users using space. Consider factors for analysis of ward and models based on this study model. Select a case hospital to apply the analysis technique and conduct the nurse questionnaire and route survey of the hospital. Establish a framework for analysis model applied with the path of nurse movements. The analysis model applies to the case hospital. The analysis results are aggregated to derive design suggestion for reference to the spatial improvement of the ward. Visible visibility to observe the bedside in the nursing station, visibility to observe the beds in the nurse's path, and visibility to observe patients moving in the nurse's path were derived from visual access frequency and exposure frequency. The survey of nurses' movements at the site allowed the nurses to calculate the distance required to move. Reflecting the path of nurse movement, a model was presented for a comprehensive analysis of nursing distance and nursing visibility, which could lead to improvement in the observation and visibility of nurses and the layout of patient rooms or day rooms.
