혈관 질환 위험인자의 가족력은 이미 잘 알려져 있으며 최근 심혈관 질환의 위험인자를 대상으로 한 연구에서는 가족력 뿐 만 아니라 배우자간의 위험인자 일치성이 있다고 밝혔다. 이는 혈관 질환 위험인자에서의 가족력은 유전적인 이유뿐 만이 아니라 환경적 요인으로 인해서도 발생한 다는 것을 암시한다. 그러나 뇌졸중이 발생한 환자에서 그 배우자간 위험인자의 일치성을 알아본 연구는 없었다. 이 연구는 본 연구를 진행하기 앞서 시행한 연구로서 뇌졸중으로 입원했던 환자를 대상으로 위험인자간의 관련성을 조사해 그 경향성을 파악하고자 하였는데 고혈압의 유무(p=0.025)와 경동맥 내막-중막 두께(r=0.479, p=0.001)에서 의미있는 연관성을 보였으나 나이를 보정하는 경우 의미가 없는 것으로 드러났다. 일반 인구 대상이거나 심혈관질환자가 대상이었던 종전의 연구 결과와는 다른 결과였다. 의미 있는 경향성을 보인 위험인자에 대해서 추후 보다 큰 규모의 연구가 필요할 것이다.

Cerebrovascular disease and coronary heart disease are the first and the fourth common causes of death among adults in Korea. Reported risk factors of these diseases are mostly alike. But some risk factors of one of these diseases may prevent other diseases. Therefore, we tried to compare and discriminate the risk factors of these diseases. We recruited four case groups and four control groups among the inpatients who were admitted to Wonju Christian Hospital from March, 1994 to November, 1995. Four control groups were matched with each of four case groups by age and sex. The number of patients in each of four case and control groups were 106 and 168 for acute myocardial infarction(AMI), 84 and 133 for subarachnoid hemorrhage(SAH), 102 and 148 for intracerebral hemorrhage(ICH), and 91 and 182 for ischemic stroke(IS) respectively. Factors whose levels were significantly higher in AMI and IS than in responding control group (RCG) were education, economic status, and triglyceride. Factors whose levels were significantly lower in hemorrhagic stroke than in RCG were age of monarch, and prothrombin time. The factor whose level was higher in AMI than ill RCG was uric acid. The factor whose level was higher in AMI, ICH, and SAM than in RCG was blood sugar. Factors whose levels were significantly higher in all the case groups than in RCG were earlobe crease, Quetelet index, white blood cell count, hemoglobin, hematocrit, and total cholesterol. The list of risk factors were somewhat different among the four diseases, though none of the risk factors to the one disease except prothrombin time acted as a preventive factor to the other diseases. The percent of grouped cases correctly classified was higher in the discrimination of ischemic diseases(AMI and IS) from hemorrhagic diseases(SAM and ICH) than in the discrimination of cerebrovascular disease from AMI. The factors concerned in the discrimination of ischemic diseases from hemorrhagic diseases were prothrombin time, earlobe crease, gender, age, uric acid, education, albumin, hemoglobin, the history of taking steroid, total cholesterol, and hematocrit according to the selection order through forward selection.

Purpose : Cardiovascular disease is major factor of mortality in worldwide. Previous studies shown that the socioeconomic factors, nutrition factors, health behavior factors, biological factors and co-morbidity are increasing a prevalence of cardiovascular disease. Method : This study examined the risk factors for cardiovascular disease among adults aged 30 years and older using the data from the 2012 to 2014 Korean National Health and Nutrition Examination Survey (KNHANES). The study participants were 7,555 Cardiovascular disease includes hypertension, stroke, angina pactoris, and myocardial infarction. Descriptive statistic and multivariates logistic regression were calculated. Result : The overall prevalence of cardiovascular disease was 31.16% in the participants. Cardiovascular disease was significantly associated with gender, age, income, education, marital status as socioeconomic factors in unadjusted model. After adjusting socioeconomic status variables, past smoker (OR 1.27, 95% CI 1.05-1.55), obesity (OR 7.14, 95% CI 4.21-12.11), skipping a meal (OR 2.79, 95% CI 2.46-3.16), HDL-C (OR 0.99, 95% CI 0.98-0.99) and WC (OR 1.06, 95% CI 1.05-1.07) were associated with cardiovascular disease. Conclusion : The results marked the importance of finding high risk groups and an early management of cardiovascular disease.

In medical research, the risk factors associated with human diseases need to be identified to predict the incidence rate and determine the treatment plan. Logistic regression analysis is primarily used in order to select risk factors. However, individuals who are unfamiliar with statistics outcomes have trouble using these methods. In this study, we develop a nomogram that graphically represents the numerical association between the disease and risk factors in order to identify the risk factors for delirium and to interpret and use the results more effectively. By using the logistic regression model, we identify risk factors related to delirium, construct a nomogram and predict incidence rates. Additionally, we verify the developed nomogram using a receiver operation characteristics (ROC) curve and calibration plot. Nursing home, stroke/epilepsy, metabolic abnormality, hemodynamic instability, and analgesics were selected as risk factors. The validation results of the nomogram, built with the factors of training set and the test set of the AUC showed a statistically significant determination of 0.893 and 0.717, respectively. As a result of drawing the calibration plot, the coefficient of determination was 0.820. By using the nomogram developed in this paper, health professionals can easily predict the incidence rate of delirium for individual patients. Based on this information, the nomogram could be used as a useful tool to establish an individual's treatment plan.

Purpose: The purpose of this study was to determine the significant factors for risk estimate of aspiration and to evaluate the efficiency of the dysphagia assessment tool. Methods: A consecutive series of 210 stroke patients with aspiration symptoms such as cough and dysphagia who had soft or regular diet without tube feeding were examined. The dysphagia assessment tool for aspiration was compared with videofluoroscopy using Classification and Regression Tree (CART) analysis. Results: In CART analysis, of 34 factors, the significant factors for estimating risk of aspiration were cough during swallowing, oral stasis, facial symmetry, salivary drooling, and cough after swallowing. The risk estimate error of the revised dysphagia assessment tool was 25.2%, equal to that of videofluoroscopy. Conclusion: The results indicate that the dysphagia assessment tool developed and examined in this study was potentially useful in the clinical field and the primary risk estimating factor was cough during swallowing. Oral stasis, facial symmetry, salivary drooling, cough after swallowing were other significant factors, and based on these results, the dysphagia assessment tool for aspiration was revised and complemented.

Objectives : This study was aimed to investigated the warning signs and its relationship with the other characteristics in acute stroke patients. Methods : 225 acute stroke patients were recruited at the Department of Cardiovascular and Neurologic Diseases (Stroke Center) of Kyung Hee University Oriental Hospital from October 2005 to September 2006. We evaluated their stroke type with brain MRI, their warning signs, and general characteristics such as age, sex, past history, risk factors, etc. Results : 225 subjects were included in the final analysis. In the subjects' general characteristics, the most common etiology of stroke was small vessel occlusion. In the assessment of the subjects' warning signs, the frequency of tension felt at the cervical area was highest followed by blepharospasm, sensory dysfunction (one side of numbness, tingling sensation, dead sensation), one side paralysis or weakness, etc. After analyzing etiology, cerebral hemorrhage had more facial spasm sign and hypertension than cerebral infarction. On the other hand, cerebral infarction had more diabetes and sensory dysfunction (one side of numbness, tingling sensation, dead sensation) than cerebral hemorrhage. Among stroke locations, subjects with their brain lesion in the cortex had more warning sings of motor dysfunction such as one side paralysis, or weakness. Multiple lesions showed a close relationship with smoking habit and were more common in males than in females. The under 65 years old group were more commonly associated with alcohol consumption, accidental mental stress and blepharospam than the over 65 years old group. In the group of under 65 years old, males more commonly had lesions in occipital lobe, alcohol consumption and smoking habit than females. Otherwise, females more commonly had vision dysfunction and blepharospasm than males. In the group of over 65 years old, males more commonly had cortex lesion than females. On the other hand, Females more commonly had accidental mental stress than males. Conclusions : We observed various warning signs and their distribution in acute stroke patients. The subjects' brainlesions and their etiology seemed to affect the features of the warning signs. Hypertension, diabetes and hyperlipidemia were also related to etiology of stroke and some habitual problems such as smoking and drinking seemed to reduce the age of stroke ictus. Although a concrete conclusion can hardly be drawn from this study, it reminds physicians of the importance of warning signs which appear among their patients.

Background : Cerebrovascular disease is a major cause of death and disability in adults. Silent cerebral infarction (SCI) portends more severe cerebral infarction or may lead to insidious progressive brain damage resulting in vascular dementia. Known cardiovascular risk factors, such as arterial hypertension, diabetes mellitus, smoking, hyperlipidemia and ischemic heart disease may increase the risk of SCI. This study was designed to evaluate the risk factors of SCI in an apparently normal adult population. Methods : We divided 340 neurologically normal adults (mean age=59.90$\pm$8.30, men:women = 146:194) who underwent brain computed tomography (CT) or magnetic resonance imaging (MRI) at the Stroke Medical Center in Daejeon University Oriental Medicine Hospital in two groups, Silent inf. and Controls,and analyzed risk factors of SCI by interview, physical examination and blood test. Risk factors of SCI were assessed by interview, physical examination and blood test. We performed Pearson's chi-square test and two-sample t-test for univariate analysis and multiple logistic regressions for multivariate analysis to evaluate risk factors of SCI. Results : Old age, diabetes mellitus, and high lactate dehydrogenase (LDH) levels were associated with SCI on univariate analysis. Diabetes mellitus was demonstrated to be an independent risk factor for SCI on multivariate analysis. Conclusions : Advanced age, diabetes mellitus, and LDH levels are associated with SCI.

Korean Industrial Standards for lightning protection system complies with IEC standards. However, the standards are applicable only to buildings and structures more than 20 meters in high. Therefore, it is necessary to determine whether lightning protection system should be installed on structures lower than 20 meters high. This paper proposes an efficient method of assessing risk against lightning of structures lower than 20 meters high. The method suggests simplified lightning protection system and provides selecting an appropriate protection level. The suggested method assumes that structure under assessment has no lightning protection system and there is no person around the structure at the moment of lightning stroke. A simplified method of assessing the risk to human within the structure is developed by adopting the general assessment factor. The selection of a protection level is possible by comparing tolerable risk with physical damage risk caused by a direct lightning. Finally, this paper gives ways to establish surge protection measures when a structure with lightning risk is within a radius of 2km from the assessed structure even if this structure requires no lightning protection system.
