It is widely known that patients' utilization pattern for medical care facilities and the patientflow are influenced by multi-factors, such as demographic characteristics, structural characteristics of society, socio-psychological characteristics(value, attitude, norms, culture, health behavior, etc.), economic characteristics(income, medical price, relative price, physician induced demand, etc.), geographical accessibility, systematic characteristics(health care delivery system, payment methods for physician fees, form of health care security, etc.), and characteristics of medical facilities(reliability, quality of medical care, convenience, kindness, tec.). This study was conducted to research the mechanism of patient-flow according to changes of health care system(implementation of national health insurance, health care referral system and regionalization of health care utilization, etc.) and characteristics of medical facilities(ownership of hospital, characteristics of medical services, non-medical characteristics, etc.). In this study, the fact could be ascertained that the patient-flow had been influenced by changes of health care system and characteristics of medical facilities.

Stroke is usually associated with the cerebral blood flow of the central nervous system. However, studies concerning the effects of neurologic sysmptoms induced from stroke on the peripheral blood flow has not taken place sufficiently. To ascertain the feasibility of a blood flow meter adopting to use doppler ultrasonogrphy, under the prospect that hemiparesis induced from stroke may have effect on the peripheral blood flow, the peripheral blood flow velocity was observed. The control group made up of healthy people without any factors capable of effecting the peripheral blood flow velocity, and patient group which consist of hemiparetic people induced from stroke, were recruited. Volumes of recruitment are 21 persons in the patient group, and 29 persons in the control group, but the final numbers of people are 17 and 21 respectively because of the inconsistancy in the method of the test. The non-invasive method of Doppler effect of Ultrasound was used to measure the blood flow velocity. The blood flow velocity in the peripheral part of left and right fourth fingers:dorsal branches of proper palmar digital artery to dorsum of distal phalanges, was measured in the control group and patient group through Doppler Ultrasound. In comparison of the control group and the patient group, the systolic blood flow velocity from the peripheral part of the upper extremity was lower in the patient group than that of the control group. According to such results, it is concluded that hemiparesis induces the reduction of the peripheral blood flow velocity in the systolic phase.

In the present study, the characteristics of blood flow inside a carotid artery numerically investigated with shear rate specific blood viscosity. To simulate the blood flow with a patient-specific arterial geometry, the geometry of a carotid artery was constructed from 2D rain MRA data. The measured data of blood flow velocity at the common carotid artery were used as boundary conditions of the simulation. For the blood rheology data to be used in the simulation, the patient specific blood viscosity over the whole ranges of shear rate was obtained using $BioVisco^{TM}$. From the numerical results of the blood flow in the carotid artery, the increase of blood viscosity and the decrease of wall shear stress could be found in the carotid bifurcated region, more specifically at the post-plaque dilated region. These characteristics of blood viscosity and wall shear stress can be used more precisely and efficiently to predict the region vulnerable to plaque growht or thrombosis on top of the plaque.

Background: Patient-controlled analgesia (PCA) has been widely used as an effective medical treatment for pain and for postoperative analgesia. However, improper dose errors in intravenous (IV) administration of narcotic analgesics from a PCA infusion pump can cause patient harm. Furthermore, opioid overdose is considered one of the highest risk factors for patients receiving pain medications. Therefore, accurate delivery of opioid analgesics is a critical function of PCA infusion pumps. Methods: We designed a microbalance method that consisted of a closed acrylic chamber containing a layer and an oil layer with an electronic balance. A commercially available infusion analyzer (IDA-5, Fluke Co., Everett, WA, USA) was used to measure the accuracy of the infusion flow rate from a commercially available smart PCA infusion pump (PS-1000, UNIMEDICS, Co., Ltd., Seoul, Korea) and compared with the results of the microbalance method. We evaluated the uncertainty of the flow rate measurement using the ISO guide (GUM:1995 part3). The battery life, delay time of the occlusion alarm, and bolus function of the PCA pump were also tested. Results: The microbalance method was good in the short-term 2 h measurement, and IDA-5 was good in the long-term 24 h measurement. The two measurement systems can complement each other in the case of the measurement time. Regarding battery performance, PS-1000 lasted approximately 5 days in a 1 ml/hr flow rate condition without recharging the battery. The occlusion pressure alarm delays of PS-1000 satisfied the conventional alarm threshold of occlusion pressure (300-800 mmHg). Average accuracy bolus volume was measured as 63%, 95%, and 98.5% with 0.1 ml, 1 ml, and 2 ml bolus volume presets, respectively. A 1 ml/hr flow rate measurement was evaluated as 2.08% of expanded uncertainty, with a 95% confidence level. Conclusion: PS-1000 showed a flow accuracy to be within the infusion pump standard, which is ± 5% of flow accuracy. Occlusion alarm of PS-1000 was quickly transmitted, resulting in better safety for patients receiving IV infusion of opioids. PS-1000 is sufficient for a portable smart PCA infusion pump.

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.

다음은 요뇌경색의 대표적인 치료법과 예방법중 하나는 대뇌혈류를 증가하는 방법이다. 대뇌 부위로 가는 혈류량을 우회적으로 증가시켜 최종대뇌 손상부위를 최소화 하는 것을 목표로 한다. 이와 같은 대뇌혈류를 증가시키는 방법은 약물에 의한 치료방법과, 수술에 의한 방법 등 칩습적으로 행해져왔다. 하지만 이러한 침습적인 방법은 환자에게 수술의 부담을 주며 합병증 등의 위험에 노출되어 있는 단점이 있다. 본 논문에서는 이러한 침습적인 치료방법의 단점을 보완하고자 비침습적 대뇌혈류증가 장치를 제안한다. 기존의 대뇌 혈류 증가 장치의 단점을 보완하기 위해 가압식 측정법을 적용하여 환자의 사지 혈압을 정확하게 측정하고 사지압박을 실시하여 대뇌부위로 가는 혈류량을 우회적으로 증가시켜 혈류증강 치료를 실시한다. 이는 기존의 침습적 대뇌혈류증강 치료와 비교하여 합병증의 우려가 없고 환자에게 부담을 주지 않으며 대뇌혈류량을 의미 있게 증가시키기 때문에 환자에게 선택적으로 사용될 수 있다.

Atrophic rhinitis is characterized by mucosal atrophy, bony absorption, persistent fetid odor and resistance to medical and surgical treatment. Stellate ganglion block (SGB) can be used as a therapeutic modality by improving the regional blood flow through sympathetic blockade. We present a case of a 57 year-old male patient who had been treated unsuccessully for atrophic rhinitis for several years by surgical and conservative measures. The patient presented at our pain clinic with shoulder pain and received stellate ganglion block once or twice a week. He received more than 75 SGBs in addition to the routine conservative treatment for atrophic rhinitis. As the number of blocks performed increased, the patient demonstrated subjective symptom relief. We measured regional mucosal blood flow using a laser doppler flowmeter after the 28th, 63rd and 75th blocks. Nasal mucosal blood flow was improved by 4.9%, 28.8% and 36.3% respectively. We also were able to observe the recovery of mucosal atrophy to an almost normal level by nasal endoscopy. The patient is currently free of symptoms and is being followed up on an outpatient bases.
