현재 심혈관 질환은 암 다음으로 높은 사망 원인으로 기록되고 있어 심혈관 질환에 대한 초기 진단은 질환의 치료에 매우 중요한 문제로 대두되고 있다. 본 논문에서는 SVM을 이용하여 심혈관질환 환자의 질환 단계를 예측하였다. 일반적으로 이진분류에 사용되는 SVM을 이용하여 정상 및 질환 $1{\sim}3$기의 총 4가지 분류가 필요한 다분류 분류문제를 처리하기 위해서 논문에서는 독립적 학습된 단일 SVM 분류기들을 결합하여 분류를 수행하는 SVM 앙상블 방법을 사용하였다. 단일 분류기의 결합은 Majority voting, 최소자승에러기반 가중치 부여, 2단계층 결합 등의 방법으로 수행하여 심혈관 질환 분류에 적합한 앙상블의 구성을 시도하였다. 실험 데이터는 (주)제노프라의 압타머 칩 데이터를 사용하였다. 서로 다른 데이터를 이용하여 학습된 이종의 SVM들을 결합한 결과 질환단계 예측에 있어서 단일 SVM을 이용하여 질환 단계를 예측하는 경우 보다 향상된 질환단계 예측 성능을 관찰할 수 있었으며, 심혈관 질환의 예측에 대해서는 단일 SVM 분류기의 2단 계층 결합법이 가장 좋은 성능을 보임을 확인하였다.

심장혈관질환은 우리나라 사망 원인의 두 번째를 차지하는 질병으로 사회가 서구화되고 이에 따라 우리의 식생활 문화도 서구화되면서 심혈관질환 발생은 점점 증가하고 있는 추세이다. 심혈관질환 치료 및 예방을 위해서는 생활습관 조절(the rapeutic life style change)이 필수적이며 식사요법은 생활습관 조절의 핵심을 이루는 심혈관질환 예방과 치료의 중요한 부분이다. 금번에는 심혈관질환 예방과 치료에 필수적인 식사요법을 통해 섭취하게 되는 영양소의 종류와 심혈관 질환에 미치는 영향에 관한 근거 중심으로 알아보고자 한다.

뇌졸중, 심근경색 등의 심혈관질환은 암과 더불어 우리나라의 주요 사망원인이다. 2002년 통계청이 발표한 2001년 사망원인통계를 보면 인구 10만명 당 암이 123.5명으로 1위, 뇌졸중 등 뇌혈관 질환이 73.8명으로 2위, 심장질환(허혈성 심장질환과 기타 심장질환 포함)이 34.2명으로 3위였다. 이러한 심혈관질환의 예방을 위해서는 평소 뇌혈관질환을 일으킬 수 있는 위험인자들을 잘 관리할 필요가 있다. 사망률이 높은 심혈관질환의 주요 위험요인은 성별, 연령 등 선천적으로 타고나는 고정요인과 흡연, 비만 등 본인의 노력에 따라 생활습관을 바꿔 위험을 낮출 수 있는 변동요인으로 나눌 수 있다. 성별, 연령은 바꿀수 없지만 생활습관은 바꿀 수 있다. 심혈관 질환 예방에 있어서 가장 중요한 것은 기본적인 건강관리 수칙인 금연, 과음하지 않기, 균형있는 올바른 식생활, 규칙적인 운동, 표준체중 유지하기, 정기검진 등이다.특히 심혈관 질환은 채소류와 식물성 단백질, 식물성 지방 등을 위주로 한 식이요법이 도움을 줄 수 있고 튼튼한 혈관을 가지기 위해서 질 좋은 단백질과 비타민ㆍ무기질을 충분히 섭취해야 하며 콜레스테롤의 배설을 돕기 위해 섬유소가 충분한 식사를 한다. 갑자기 추워진 날씨로 생명을 다투는 뇌졸중이나 협심증, 심근경색 등 심혈관 관련 질병이 발생하기 쉬운 겨울철이다. 행사가 많은 연말에 과음을 삼가며 금연하고, 평소 담백한 한식 위주의 식사, 꾸준한 운동 등으로 건강관리에 힘써서 치명적인 심혈관 질환에 미리미리 대비하도록 한다.

A lot of studies have investigated the role of psychosocial and behavioral risk factors in the etiology and pathogenesis of cardiovascular disease. On the basis of prospective population studies that found a relationship between Type A behavior and cardiac morbidity and mortality independent of traditional risk factors, Type A behavior was declared a risk factor for the development of coronary heart disease. Additionally, recently proposed, a new personality construct, Type D personality have been reported to be associated with the increased risk for cardiovascular morbidity and mortality. In Korea, however, there were few studies about these issues. This article attempts to provide an overview of accumulating evidences on the Type A behavioral pattern and Type D personality related with cardiovascular disease to offer new directions for research.

The subjects consisted of 60 healthy men who absence of cardiopulmonary diseases, orthopedic diseases, and metabolic diseases. The difference of physical fitness, body composition, cardiovascular risk factors, and psychological characteristics for security guards' working type were examined using one-way ANOVA through SPSS 12.0 version and was treated for the post hoc test when the difference appeared significantly. According to the result, first, there were higher level for the physical fitness according to the security guards' position and it increases body composition and cardiovascular risk factors from higher position. Second, physical fitness level is higher, body composition and cardiovascular risk factors is lower in the security guards for the field service than the security guards on inside duty according to the security guards' working type. Third, it decreases body composition and cardiovascular risk level when the physical fitness level is getting increase for the security guards. In conclusion, it needs to have a physical activity with aerobic system for the security guards of leading members and inside service to decrease the overweight or obesity and cardiovascular risk level.

The purpose is to investigate correlation of periodontal disease and cardiovascular disease among those living alone and living with family by using 6th Korean National Health and Nutrition Examination Survey. According to general characteristics, cardiovascular diseases were found to be related to gender, education level of those living with family; and age and income level of elderly living alone. The oral health status, oral health patterns and cardiovascular disease distribution of both groups for the past year were examined. The relationship between cardiovascular disease and periodontal disease was related to hypertension only in the living with family. Cardiovascular disease and periodontal disease are the most common diseases so considering the two diseases together is necessary to check the health status in the future.

The purpose study is to investigate the correlation between cardiovascular symptoms and factors in police officers, to provide basic data for a systematic and effective resource management of radiation workers in the future. This study was conducted on police officers who visited the national police hospital and who underwent 201Tl-SPECT for the diagnosis of cardiovascular diseases. In study result, smokers than non-smokers 1.80 times higher cardiovascular disease. Beside, person with hypertension than those who do not have hypertension 1.63 times higher cardiovascular disease. And, the probability of cerebrovascular disease was 1.82 times higher in patients with a low HDL level.

The purpose of this study was to evaluate the clinical availability of ankle-brachial index(ABI) according to severity of cardiovascular disease. The subjects of this study were the patients who had ABI in a general hospital. In this study, total 441 patients were enrolled for analysis. Electric medical records were reviewed to investigate the result of ABI and severity of cardiovascular disease measured vessel disease and Gensini score. Collected data were analyzed using SPSS 21.0 program. Subjects with $ABI{\leq}0.90$ and > 0.90 were classified as having abnormal and normal ABI. There were significant differences in vessel disease categorization($x^2=4.731$, p=.030) and Gensini score(t=2.351, p=.019) between two groups. Therefore, ABI is an effective and non-invasive tool for the diagnosis of cardiovascular disease with high severity. ABI is a valuable predictive index of ischemic heart disease.

The purpose of this study was to investigate the effect of cardiocerebrovascular disease prevention program on cardiovascular risk factors and quality of life in the elderly. A non-equivalent control group pretest-posttest design was used. Participants were 44 elderly who registered at the public health center. The experimental group(n=22) received the cardiocerebrovascular disease prevention program for the elderly 8 times. There were significant differences in the systolic blood pressure(t=-2.419, p= .020), diastolic blood pressure(t=-2.226, p= .031), blood glucose(t=-2.071, p= .045) and quality of life(t=2.511, p= .016) between the experimental group and the control group. The results suggest that cardiovascular disease prevention program can be an effective strategy to reduce cardiovascular risk factors and improve the quality of life of the elderly.

Purpose : Turner syndrome (TS) is a disorder in which various anomalies can be accompanied, especially cardiovascular, renal, thyroid and auditory problems. The aim of this study is to identify the incidence of these disorders in patients with TS according to karyotype. Methods : We reviewed medical records of 90 patients with TS diagnosed by chromosomal analysis in 4 hospitals from Jan 1998 to Dec 2007. We evaluated these cases by prepared protocol of 4 medical problems.Results : The distribution of karyotype was 45,X (47.8%), mosaic pattern (34.4%) and structural aberration group (17.8%). Renal anomalies, cardiovascular anomalies, thyroid disorders and auditory problems are accompanied in 4.4%, 10.0 %, 11.1% and 5.6%, respectively. 45,X group had renal anomalies (7.0%), cardiovascular anomalies (18.6%), thyroid disorders (9.3%) and auditory problems (11.6%). Mosaic group had renal anomalies (3.2%), thyroid disorders (12.9%), no cardiovascular anomalies and auditory problems. Structural aberration group had cardiovascular anomalies (6.3%), thyroid disorders (12.5%) and no other 2 problems. Patients with 45,X group had a significant higher incidence of cardiovascular anomalies (P =0.025). Conclusion : Our results indicate that there are differences clinically according to karyotype of TS, especially in incidence of cardiovascular anomalies.
