Objective: This study aimed to investigate the upper limb strength, active joint range of motion (AROM), and upper limb function in persons with chronic stroke using virtual reality training in combination with upper limb sensory stimulation. Design: Two-group pretest-posttest design. Methods: 20 subjects were divided into two groups of 10, the sensory motor stimulation and virtual reality training (SMVR) and virtual reality training (VR) groups. The training was conducted for 30 minutes per session, three times a week for 8 weeks.The participants' upper limb strength was measured via the hand-held dynamometer, joint angle AROM was measured via dual inclinometer, function was measured using the Jebson-Taylor hand function test and the manual function test. Results: Significant differences were observed in all groups before and after the training for upper extremity strength, AROM, and function (p<0.05). Between the two groups, the SMVR group showed significant improvement in muscle strength, AROM, and Jebsen-Taylor hand function test scores compared with the VR groups (p<0.05). Conclusions: In this study, we confirmed that sensory stimulation and VR had positive effects on upper extremity strength, AROM, and function of persons with chronic stroke. The results suggest that in the future, VR in combination with sensory stimulation of the upper limb is likely to become an effective method (a rehabilitation training program) to improve the upper limb function of persons with chronic stroke.

The characteristics of the flow processes in the cylinder of the two-stroke cycle engines have become the subject of increasing and attention owing to the simplicity and the higher power per unit weight of the two-stroke cycle engine. Among the many factors which influence on the scavenging flow, the port angle is important factor. Hence, four different type models with one inlet-port and two side-ports are studied to show the effect of port angle on the laminar scavenging flow. When the inlet-port axial is relatively larger than the side-port axial angle, it is showed that the fresh charge penetrate into the burned gas and displace it first toward the cylinder head and then toward the exhaust port. When the inlet-port axial angle is much less than the side-port axial angle, the fresh charge through the inlet-port directly move toward the exhaust port. The result showed that the model A may suppress the generation of vortices in the vicinity of inlet and side prots which restrict the sufficient supply of fresh charge and obstruct the perfect displacement of all combustion products.

This study was done to research the general information, causes of stroke, risk factors, complications during admission of geriatric CVA inpatients. We retrospectively studied 208 above 65 years old geriatric CVA inpatients treated in Ajou university hospital from 1994 to 2003 by medical record. These were divided into two groups by following years. We were gathered information about sex, onset age, cause of stroke, number of stroke, complications, housing, family, insurance, smoking, alcohol. Most of incidence of the stroke was noted in the group of young old age (65~74 years old) and old age (75~84 years old). The occurrence rate of male stroke (38.5%) was less than of female stroke (61.5%) and the ratio of male to female was 1:1.6. The occurrence rate of ischemic stroke (72.6%) was higher than of hemorrhagic stroke. The occurrence rate of ischemic stroke increased more and more at the late stage. The most common risk factors for stroke was hypertension and complications during hospitalization were neurogenic bowl and bladder. These results of epidemiologic study may help above 65 years old geriatric CVA early treatment and prevention, rehabilitation and use basic data for multiple prospective study using stroke registry.

Objectives : The objective of this article is to compare acupuncture treatment of stroke in the medical documents of the Chosun-Korea dynasty. Through such inquisition, the development process of acupuncture of stroke treatment could be found. Methods : We used Cross-comparison analysis of the contents of five medical books, HyangYakZipSungBang (HYZSB), UiRimChwarYo(URCY), DongEuiBoGam(DEBG), ChimGuGyungHumBang(CGGHB) and Saam-Acupuncture(SA) of the Chosun-Korea dynasty. Results & Conclusion : 1. Distinction between Stroke of Viscera and Stroke of Bowel was important. Firts two books divided stroke into three type. But last three books separated into Stroke of Viscera and Stroke of Bowel. 2. They emphasized Symptoms of Five Visceral Disease. They devised Symptoms of Five Visceral Disease for Stroke of Viscera treatment. This method appears very rarely in clinical medicine. 3. They used common important acupoint for treatment of stroke. Most of these acupoints exist at the limbs. 4. They chose acupoints on the opposite side against the symptom.

Objective: The purpose of this study was to investigate the effect of cervical range of motion training on the change in respiratory function growth rate at the group and individual level in stroke patients and stroke patients with tracheostomy tube. Design: A Multilevel Growth Model Methods: 8 general stroke patients and 6 stroke patients who had a tracheostomy tube inserted were subjected to cervical range of motion training 3 times a week for 4 weeks. Force vital capacity (FVC), Forced expiratory volume in the first second (FEV1), Forced expiration ratio (FEV1/FVC) and Manual assist peak cough flow (MPCF) were measured. Data were analyzed using descriptive statistics and multilevel analysis with HLM 8.0. Results: A significant difference was found in the respiratory function analysis growth rate of the entire group (p<0.05), and two groups were added to the research model. The linear growth rate of respiratory function in patients with general stroke increased with the exception of FEV1/FVC (p<0.05). Stroke patients with tracheostomy tube showed a decreasing pattern except for FVC. In particular, MPCF showed a significantly decreased result (p<0.05). Conclusions: This study found that the maintenance of improved respiratory function in stroke patients with tracheostomy tube decreased over time. However, cervical range of motion training is still a useful method for respiratory function in general stroke patients and stroke patients with tracheostomy tube.

Objective : Rapid increase in aged population and westernization of lifestyle have modified epidemiological status of stroke. The purpose of this study is to analyze changing trends of stroke epidemiology in South Korea. Methods : We reviewed retrospectively medical records of 1,124 cases diagnosed as stroke among 54,534 patients who visited the Emergency Medical Center at our hospital from January 1994 to December 1996 (Group A). Also, we evaluated 1,705 cases diagnosed as stroke among 55,381 patients who visited to the same hospital from January 2003 to December 2005 (Group B). The variable features of stroke, such as age, sex, seasonal variation and distribution of stroke subtypes were studied by comparing group A with B. Results : In group A, hemorrhagic stroke (67.9%) was more prevalent than ischemic stroke (32.1%). However, group B showed that the ratio of hemorrhagic stroke (40.3%) to ischemic stroke (59.6%) has been reversed. The highest incidence of stroke was noted in their sixties and seventies of age in group B, which was older than that of group A. In group A, male ischemic stroke (IS) patients outnumbered female patients (1.26:1). Moreover, this gender disproportion became higher in group B (1.53:1). In group A, the number of male intracerebral hermorrhage (ICH) patients were similar to that of female patients (0.97:1). However, male ICH patients outnumbered female patients in group B (1.23:1). As for subarachnoid hemorrhage (SAH), female patients outnumbered male patients more than two-fold in both groups. Both groups showed that the occurrence of ischemic stroke was highest in summer, but that of hemorrhagic stroke was the highest in winter. Conclusion : This study showed the changing trends of stroke in its distribution of subtypes. Multicenter prospective study using stroke registry would be required for the determination of national epidemiologic trends.

In this paper, the numerical simulation of the method of characteristics for a two-stroke SI engine was carried out, and the scavenging efficiency and the performance of single engine with two types of exhaust system, that is, a pipe exhaust system and a tuned exhaust system, were predicted and compared. The conculusions are obtained as follows. (1) The method of characteristics of hometropic flow considering the friction and the variation of area is useful to predict the scavenging efficiency and the performance of the two-stroke engine. (2) The shape of exhaust system effects directly on the scavenging and the trapping efficiency. (3) A tuned exhaust system consisted of the diffuser and the convergent nozzle makes the plugging pulse and therefore enhances the scavenging and the trapping efficiency. (4) It may be possible to design the optimum exhaust system by using the plugging pulse.

The purpose of this study was to evaluate the diagnostic indicators which are used for the identification of fire-heat pattern in stroke patients. For evaluation of diagnostic indicator, we analyzed the indicators which are composed of symptoms and signs collected from stroke patients based on the clinical records using case report form (CRF). Patients had a first-ever stroke within 1 month after the onset of stroke. Pattern identification was performed and decided by two independent physicians. Two patient groups that consist of fire-heat pattern and the other patterns were compared to isolate important indicators affecting the fire-heat pattern identification of stroke patients. The 8 indicators among 16 fire-heat pattern indicators were significantly more frequent compared with non fire-heat pattern group. Logistic regression analysis revealed that 5 indicators among fire-heat indicators were significantly sensitive indicators being capable of identification of fire-heat pattern. But two of them was from the indicators of dampness-phlegm pattern and yin deficiency pattern. Therefore, further studies are required for the development of Korean standard indicators of Fire-heat pattern identification.
