This study propose the educational potential of an activity that solves the task of one-stroke drawing of complex figures using a drag-and-drop type educational programming language such as Scratch. The problem of determining whether a given shape is capable of one-stroke drawing is a separate problem from actually finding the path of one-stroke drawing and implementing it through programming. In particular, finding a path that allows one-stroke drawing of complex shapes with regularity and implementing it through programming requires problem-solving capabilities based on the convergence of various mathematical knowledge. Accordingly, in this study, problems related to one-stroke drawing concerning polygon-related shapes, tessellation-related shapes, and fractal shapes were presented, and the results of one-stroke drawing programming of the shapes were exemplified. In addition, the mathematical knowledge and computational thinking elements necessary for the solution of the illustrated problem were analyzed. This study is significant as a new example of the mathematics education that combines mathematics and information.

Stroke, also called an attack on the brain, is a complex disease that results from the interaction of many genetic and environmental factors. StrokePortal is a comprehensive resource for information on stroke that integrates and provides essential findings regarding stroke pathology, diagnostics, and treatments, based on Oriental and Western medicine. The stroke information was collected from various sources, such as journal articles, books, websites, and news stories, and it was refined, classified, and stored into a relational database system by automatic classification and manual curation. To provide the stored information effectively to users, a specialized retrieval system, based on web interfaces, was implemented. StrokePortal provides cutting-edge information to experts; interested people, including patients and their families; and investigators to broaden their knowledge of effective treatments for patients and offer many preventive measures. It provides a specialized feature with which users can upload their information and opinions to StrokePortal, which will enrich and mature the content even further. StrokePortal is freely accessible at http://genomics.kribb.re.kr/StrokePortal/.

The purpose of this study was to investigate relationships between self-care knowledge and compliance of ischemic stroke patients with diabetic. The participants were 117 ischemic stroke patients with diabetics who were outpatients at the P university hospital. Data were collected from July 1 to August 31, 2013. Data were analyzed using SPSS 18.0., specifically descriptive statistics, t-test, ANOVA, and Pearson's correlation analysis. Total mean score and correct answer ratio of self-care knowledge were 14.69 points, 63.9%. Total mean score and compliance ratio of self-care compliance were 2.24 points, 44.8%. The correlation coefficient between self-care knowledge and compliance was a significant positive correlation (r=.54, p<.001). Among sub-elements, diet(r=.24, p=.011), medication(r=.43, p<.001), living habits(r=.19, p=.042) and cautions and warnings(r=.45, p<.001) were significant positive correlations. Based on the results of this study, we need to develop integrated nursing intervention education programs for self-care knowledge and compliance promotion of ischemic stroke patients with diabetic.

Purpose: The purpose of this study was to compare the effects of the FES-gait with augmented feedback training to the FES alone on the gait and functional performance in individuals with chronic stroke. Methods: This study used a pretest and posttest randomized control design. The subjects who signed the agreement were randomly divided into 12 experimental groups and 12 control groups. The experimental groups performed two types of augmented feedback training (knowledge of performance and knowledge of results) together with FES, and the control group performed FES on the TA and GM without augmented feedback and then walked for 30 minutes for 40 meters. Both the experimental groups and the control groups received training five times a week for four weeks. Results: The groups that received the FES with augmented feedback training significantly showed a greater improvement in single limb support (SLS) and gait velocity than the groups that received FES alone. In addition, timed up and go (TUG) test and six minute walk test (6MWT) showed a significant improvement in the groups that received FES with augmented feedback compared to the groups that received FES alone. Conclusion: Compared with the existing FES gait training, augmented feedback showed improvements in gait parameters, walking ability, and dynamic balance. The augmented feedback will be an important method that can provide motivation for motor learning to stroke patients.

Objectives: This study evaluated the effects and relevant factors of community-based education and advocacy intervention on stroke awareness among the general population. Methods: The study enrolled 505 community-dwelling adults aged 19 years or older who completed a survey before and after a community-based intervention held between May 2014 and December 2014. Trained staff collected data about knowledge of five stroke warning signs, emergency response, golden window of time (${\leq}3h$), and demographics. Results: After the intervention, public awareness of all five stroke warning signs increased significantly from 26.5% to 33.9% (p=0.011). Public awareness of the golden window of time also increased significantly from 70.1% in April 2014 to 75.8% in December 2014 (p=0.040). In a multivariate logistic regression analysis, older age, higher education level, and exposure to stroke-related public service announcements or educational materials were significant predictors of knowledge of all five warning signs for stroke. Conclusions: Comprehensive community-based intervention is effective for improving public awareness of the warning signs of stroke and the golden window of time.

Background : Low level laser therapy may be an effective method to protect tissue damage in acute stroke. Recently, series of clinical studies on the basis of animal experiments report efficacy and safety of laser therapy at early stages of acute stroke. Laser promotes mitochondrial ATP synthesis to reduce cell death by ischemic infarction. Objectives : To report possibility of non-invasive laser therapy for acute stroke by reviewing literature about its effectiveness, safety and mechanism. Methods : We searched papers using PubMed and 'Web of Knowledge' of Thomson ISI, using the keywords "Laser Therapy, Low-Level" and "Stroke". Limitations were last 10 years of publications and only in English. Search range includes RCTs, clinical reports, reviews and animal experiments. Papers not matched with inclusion criteria were excluded. Results : A total 223 studies were found, 203 excluded during title and extract screening. After scanning 20 papers the final 2 serial RCTs were selected and analyzed. They reported that transcranial laser therapy led in neuroprotective effect for acute stroke patents. Clinical evaluation factors showed favorable trend and initial safety. Conclusions : Non-invasive laser secured safety of clinical application. It may be a favorable choice for the acute stage of stroke.

Heat stroke can lead multi-organ damage with hemorrhage and necrosis in the lungs, heart, liver, kidneys, brain and Ut. Heat stroke occurs when the elevation of core body temperatures induce a failure of thermoregulatory mechanism. A four-year-old male African Lion(Panthera leo) showed clinical signs such as panting, tachycardia, hyperthermia, unconsciousness and mydriasis under He hish humidity and hot weather. Clinical treatment and pouring cool water was unsuccessful. Grossly, congestion of lungs and pleura was observed. Yellowish discoloration was observed in the renal cortex. Microscopically, the coagulative necrosis in kidney and congestion of lungs and spleen were observed. In our knowledge, this case was closely associated with acute heat stroke.

Purpose: The purpose of this study was to explore the influencing factors on the family caregivers burden who have has inpatients with acute stroke. Methods: Subjects were 126 family caregivers who have has inpatients with acute stroke. Data were collected by questionnaires. The collected data were analyzed by t-test, ANOVA, Scheffe's test, Pearson's coefficients and multiple regression. Results: The Anxiety of family caregivers was identified as a determinant of family caregivers burden who have has inpatients with acute stroke by the multiple regression analysis (${\beta}=.58$, p<.001). Gender and low cognitive function of inpatients were significantly related to family caregivers burden. And knowledge about care (r=-.27, p=.002) was correlated with anxiety significantly. Conclusion: The family caregivers burden is not only an important issue for nursing but also major nursing problem to be addressed nurses. Family caregivers with acute stroke inpatients feel more anxiety than family caregivers with other illnesses. The anxiety of family caregivers is important especially to the family caregivers who have to care acute stroke inpatients to reduce their burden.

Apraxia of phonation (AOP) has often been described as a feature of apraxia of speech or of severe non-fluent type of aphasia. Pure AOP is rare and, to our knowledge, only two cases have been reported. Brain lesion sites of the reported cases were not those sites known to be responsible for apraxia of speech. This study presents a case of AOP which resulted from the secondary stroke in the left corona radiata immediately following the first stroke in the left temporoparietal lobe. A 61-year old right-handed man shwoed a global type of aphasia after the first cerebral infarction, but was able to generate spontaneously some short fragments of speech. On the day after the first infarction, he suffered from the secondary infarction, leaving him a complete loss of voluntary phonation. He did not showed any significant change in language functions. Several occurrences of involuntary phonation were observed upon laughing or crying. He was also able to cough unintentionally. A vidoe-stroboscopic examination failed to reveal any evidence of structural and functional impairment in larynx. Although this case is not of pure form of AOP, AOP appeared after the secondary stroke without significant changes of language impairment since the first stroke. Therefore, AOP may be a consequence of the brain lesion from the secondary stroke even though we cannot rule out the possibility of an additive effect of the secondary to the first stroke.

Purpose: This study was conducted to develop a self-management program using goal setting for patients after a stroke. The program was based on a theory-based Goal setting and Action Planning framework (G-AP), and the effectiveness of the program was examined. Methods: A non-equivalent control group pretest-posttest design was used. The experimental group (n=30) received the self-management program using goal setting based on the G-AP over 7 weeks. The education was delivered individually with a specifically designed stroke workbook. The control group (n=30) received only patient information leaflets about stroke. Results: There were significant differences between the two groups. Stroke knowledge, self-efficacy, and health behavior compliance were significantly higher (all p<.001), and hospital anxiety (p<.001) and depression (p<.001) were significantly lower in the experimental group compared to the control group. Conclusion: This self-management program using goal setting based on a G-AP was found to be useful and beneficial for patients in stroke rehabilitation settings.
