The effect s of social support on post-stroke depression were investigated. Social support was classified into three categories : primary caregiver's, significant other's, and professional support. And primary caregiver's and significant other's support were divided into their relation, living state (which means they living together or not), frequency which they met at, and perceived satisfaction about the support, respectively. Professional support was divided into number of professionals who take care of, frequency they met at, and perceived satisfaction. The subjects were 254 stroke patients who had been discharged and were taken follow-up care at the out patient department. The depression was measured using CES-D. Out of the primary caregiver's support, only relation and perceived satisfaction were identified to affect the post-stroke depression. The patients who primarily their spouse takes care of were less depressed than those who their adult children take care of. None of the significant other's support affects the post-stroke depression. Only perceived satisfaction of the professional support was found to affect the post-stroke depression. So it was found that the quality, not the amount, of care was important to post-stroke depression. These results also support the claim that the facilities and teaching programs for primary caregivers are necessary.

This study aims to develop the severity-adjusted length of stay(LOS) model for acute stroke patients using data from the hospital discharge survey and propose management of length of stay(LOS) for acute stroke patients and using for Hospital management. The dataset was taken from 23,134 database of the hospital discharge survey from 2004 to 2009. The severity-adjusted LOS model for the acute stroke patients was developed by data mining analysis. From decision making tree model, the main reasons for LOS of acute stroke patients were acute stroke type. The difference between severity-adjusted LOS from the decision making tree model and real LOS was compared and it was confirmed that insurance type and bed number of hospital, location of hospital were statistically associated with LOS. And to conclude, hospitals should manage the LOS of acute stroke patients applying it into the medical information system.

Objectives: Intake of fruits and vegetables has protective effects against stroke attack. This study intended to examine the status of consuming fruits and vegetables and to find out which factors may influence the frequency of consumption of fruits and vegetables in individuals with a history of stroke. Methods: The data of 208 subjects from 5th (2010, 2011) Korea National Health and Nutrition Examination Survey (KNHNES) who reported a stroke diagnosis was used for analysis. To identify major factors influencing the consumption of fruits and vegetables, a classification-tree analysis was carried out. Results: Among those who reported a stroke diagnosis, the frequencies of consumption of fruits and vegetables were influenced by their age, place of residence (urban or rural), economic status, educational level, occupation, number of family members, frequency of eating out, and having meals (breakfast or lunch) with family members. Two factors from fruits and three factors from vegetables were generated by exploratory factor analyses. Urban residents ate fruits and vegetables more frequently in all factors than rural residents. Eating frequencies of 'seasonal fruits (orange, apple, strawberry, melon, pear and watermelon)', 'easily-accessible fruits (persimmon, tangerine, grape, peach, banana)', and 'Western-style vegetables (cabbage, mushroom, carrot, tomato, spinach)' were influenced by the socioeconomic status. Eating frequencies of 'Korean-style vegetables (bean sprout, radish leaves, pumpkin/squash, sea weed)', 'preserved vegetables (Korean cabbage, radish, laver, cucumber)' were influenced by having breakfast with family members. Conclusions: The results of this study suggested that by eating more fruits and vegetables, more preventive effects against secondary stroke attack are expected in stroke patients who live in the rural areas and who do not eat breakfast with family members. In addition, more outreach and education programs are needed for them.

Objectives : This study was aimed to assess the distribution of Sasang constitution(SC) in acute stroke patients. Methods : We assessed the type of SC of acute stroke patients in the oriental medical hospitals of 3 universities located in metropolitan region from October 2005 to October 2006 by Questionnaire for the Sasang Constitution Clssification II(QSCCII). We investigated general characteristics, stroke type, blood test results, alcohol drinking, smoking and dietary preferences according to SC. Results : 236 subjects were included into the final analysis. 1. This study showed that the proportion of So-yang was highest of all constitutions(45.3%). And the body weight, body mass index, the waist circumference(WC), the hip circumference(HC), and the WC/HC ratio recorded the significantly high result in Tae-eum. 2. In the TOAST classification, SVO was the major type occupying 81.7% in the total subjects. 3. In Tae-eum, total cholesterol, triglyceride and 2 hours postprandial plasma glucose level were the highest and fasting glucose was significantly highest of all constitutions. Conclusion : From this study, we could roughly seize the distribution of Sasang constitution in acute stroke patients. For the further research, it seems to be necessary to construct fundamental databases for stroke by increasing the number of patients and by analyzing delicate characteristics of each constitution type.

Numerical simulations are conducted to investigate the mechanism of hovering flight by single flapping wing, and to examine the effect of the phase difference between the fore- and hindwings in hovering flight by two flapping wings. The numerical method used is based on an immersed boundary method in Cartesian coordinates. The Reynolds number considered is Re=150 based on the maximum translational velocity and chord length of the wing. For single flapping wing, the stroke plane angles are $0^{\circ}$, $30^{\circ}$, $60^{\circ}$, $75^{\circ}$ and $90^{\circ}$ and the downstroke angles of attack are varied for each stroke angle. Results show that for each stroke plane angle, there is an optimal angle of attack to maximize the vertical force. Below the stroke angle of $60^{\circ}$, wake capturing reduces the negative vertical force during the upstroke. For two flapping wings, The phase lags of the hindwing are $0^{\circ}$, $90^{\circ}$, $180^{\circ}$ and $270^{\circ}$. The amplitudes of the stroke are 2.5 and 4.0 times the chord length at each phase lag. The results show that maximum vertical force is generated when the phase lag is zero, and the amplitude of the vertical force is minimum at the phase lag of $180^{\circ}$.

Purpose: To identify the relationship between medication use and falls among hospitalized stroke patients. Method: The medical records of 472 patients with strokes were reviewed using a questionnaire on falling developed by the authors. Frequencies, percentages, means, standard deviations, and t-test and ${\chi}^2$-test, multiple logistic regression analysis were done using the SAS program. Results: The rate for falls by the patients during their stay in the hospital was 14.0%. The length of stay was longer and the morbidity duration of stroke shorter in the fall group than in the non-fall group. The use of sedatives, laxatives, and antidepressants was a significant predictor of falls and was associated with increase likelihood of falling(1.82, 1.81, 1.75 times respectively). Conclusion: In hospitalized stroke patients, there was a significant association between the use of sedatives, laxatives, antidepressants and falls. The number and kinds of ingested drugs was also associated with falls. It is necessary to further analyze the causes of falls based on results of the present study.

The purpose of this study is to design electrical stimulation system for pharyngeal dysfunction(dysphagia) in stroke patients. Pharyngeal muscle group activity is important, because contracting muscles provide the driving force at the initiation of the swallow and generate the pressure gradients necessary for bolus movement into the esophagus. Although we have many treatment methods for dysphagia, electrical stimulation system will be useful for stroke patients having dysphagia. Electrical stimulation can be divided into the body stimulation and electrodes. The body stimulation is divided again into frequency counter, time control and current measurement part. These parts are to control the current intensity, frequency and stimulating time. And they can be variable according to the patient's clinical assessment. The electrode plays a role to deliver the current from the system to the muscle. Also the position of the electrode can be variable according to the treatment method. We performed the clinical experiment with the stroke patient who has swallowing disorder. The videofluoroscopy was used for the observation. From the result of clinical experiment based on electrical stimulation, we expected that the dysfunction(in pharynx) level of the patient can be improved. However we could not have enough effectiveness of the treatment because of the number of patients, patient's adaptation and treatment period. We will design the optimized electrical stimulation system based on enough clinical experiment in the future.

Objectives : In oriental medicine, Daeseungki-tang is one of the most useful prescriptions for the therapy of constipation. And we also frequently use this prescription for constipated stroke patients. Methods : In order to identify the effects of Daeseungki-tang on constipated stroke patients, we administrated the extract of Daeseungki-tang(code number, HH264) to constipated stroke patients. We gave the medicine in two ways, one-pack group and two-pack group by random allocation and investigated the amount of stool, the frequency of defecation, the stool-form and the changes of blood pressure and body temperature before and after defecation. We also tried to examine the difference of symptoms between defecation-group and non-defecation group. Results : 1. There were no distinct symptoms between defecation-group and non-defecation-group in one-pack group. 2. After defecation, body temperature decreased significantly(P<0.05) in one-pack group and blood pressure decreased significantly(P<0.05) in two-pack group. 3. As for the stool-form, watery-soft was 41.9% in the firstt defecation and 47.1 % in the second defecation. 4. In one-pack group(23 cases), 13 cases(57%) defecated and 10 cases(43%) didn't defecate. And in two-pack group(24 cases), 19 cases(80%) defecated and 5 cases(20%) didn't defecate. These results meant that the effect of Daeseungki-tang was dose dependent. The amount of stool and the frequency of defecation were also dose dependent.

Purpose: This study aimed to analyze the visual and spatial elements of the gait of a stroke patient who had diverse ankle weight loads applied, according to weight changes. Methods: The subject was a 57-year-old stroke patient diagnosed and hospitalized with a left intracerebral hemorrhage. A weight equivalent to 0%, 1%, and 2% of his body weight was applied to the area 5cm upward from the ankle using a Velcro strap. He was then trained on a treadmill, receiving a six-minute walk test to evaluate his gait ability. A gait analyzer was used to collect visual and spatial elements, such as gait distance, gait velocity, cadence, step length, stride length, and swing phase, according to a weight load equivalent to 0%, 1%, and 2% of his body weight. Results: According to the results of applying 0%, 1%, and 2% of his body weight on the ankle, except for gait velocity, his gait distance, cadence, step length, stride length, and swing phase were higher when 1% of his body weight was applied compared to 0% or 2% of his body weight. Conclusion: Applying a weight equivalent to 1% of the body weight to the ankle positively affected the visual and spatial element of the gait and heightened the efficiency of exercise during treadmill training, a gait-training tool generally used for stroke patients. However, the result is difficult to generalize because the number of subjects was small with only one subject.
