Health Risk Appraisal(HRA) is usually defined as a process by which we expect of individual's chances of death or acquiring specific diseases within a defined period of time. The concept of worksite as an area of health maintenance and promotion is newly developing. Our movement for health promotion of employees has been increasingly known in the worksite. The aim of this study is to develop health risk appraisal tools about health promotion at the worksite for employees. We performed this study by two steps; one step was to develop a HRA questionnaire of worksites in Korea, another was to evaluate the reliability of the questionnaire. For developing HRA questionnaire, we reviewed scientific examples at first, and then weighted the score by delphi. To evaluate the reliability of developed questionnaire, we carried out survey by test-retest method. A total of 131 employees completed HRA questionnaire on two times. The results are as follows. The total score of health risk in unhealthy workers was higher than that of healthy workers. The range of test-retest reliability of responses to the questionnaire was 0.57-0.94. Therefore it seems that this questionnaire was very suitable to assess the health behavior of workers. In conclusion, the developed HRA questionnaire can be used as a tool for evaluating health behavior and for providing health counseling materials.

본 연구에서는 균일하고 높은 비율의 에치 피트를 갖는 알루미늄 전극을 제작하기 위해 소프트 리소그래피를 이용하 여 알루미늄 표면에 보호층을 형성하였다. 알루미늄 표면 위에 잘 정돈된 보호층을 형성하기 위해 다양한 방법을 시 도하였으며, 보호층을 이용한 알루미늄 에칭과 보호층이 존재하지 않는 알루미늄 에칭을 비교 관찰하였다. 보호층을 이용하여 알루미늄 에칭을 진행하였을 때, 알루미늄 표면에 균일한 에칭 표면이 확인되었으나, 보호층이 존재하지 않았을 때는 불균일한 표면 에칭이 관찰되었다. In this study, etched Al electrodes with ordered arrays of pits and high aspect ratios were successively obtained using a patterned protect layer on the Al surface prepared with soft lithography method, Various methods were applied to fabricate a well ordered protect layer on the Al surface and the difference of etched Al surfaces with and without a protect layer was investigated by using SEM, It was found that the etched Al surfaces were affected by using either a protect layer or a non protect layer. As a result, the Al surface with the well ordered pits could be achieved by protect layer. However, the etched Al with nonuniform pits can be obtained without any protect layers.

최근 국내에서는 관상동맥 질환, 뇌경색, 고혈압성 심장질환같은 심혈관계 질환으로 인한 사망이 선진국에서처럼 많은 비율을 차지하고 있어 이러한 심혈관계 질환을 예방하기 위하여 위험인자들을 규명하기 위한 연구들이 활발히 진행되어왔다. 고혈압은 잘 알려진 심혈관계 위험인자로 고혈압 환자에서 심혈관계 이환율과 사망률은 큰 혈관의 병변과 상관이 있고, 고혈압 환자의 큰혈관 유순도(compliance)는 감소한다. 혈관 유순도를 직접 측정하여 수식화 할 수 있는 지표로는 맥파전도속도(pulse wave velocity, PWV)가 있다. 이러한 맥파전도속도와 혈관의 유순도는 역비례 관계에 있다. 이에 연구자는 동국대학교 경주병원 순환기내과를 방문하여 고혈압으로 진단된 45명을 대상으로 심초음파를 이용해서 맥파전도속도를 측정하여 Framingham study의 심혈관계 위험인자와의 산관과계를 알아보고, 고혈압 환자에서 어떤 심혈관계 위험인자들이 대동맥의 맥파전도속도를 결정하는지 조사하였다. 고혈압환자에서 도플러 심초음파를 이용한 맥파전도속도를 측정하여 연령과 24시간 활동 중 수축기 혈압이 상관과계가 있는 것으로 확인하였다. Background : From the Framingham study, it was reported that cardiovascular risk factors are hypertension, smoking, gender, lipid profile, diabetes mellitus, and ECG ventricular hypertrophy. The measurement of aortic pulse wave velocity(PWV) is a noninvasive technique that can integrate the vacular damages caused by the cardiovascular risk factors. The authors examined the relationship between cardiovascular risk factors of Framingham study and the PWV in hypertensive patients by doppler echocardiography. We also examined what kind of the cardiovascular risk factor determines aortic PWV. Method : For the determination of the PWV, tracings of aortic velocity were recorded by pulsed wave Doppler in hypertensive patients, non-simultaneously, at two points on the aorta : the isthmus (suprasternal approach) and near the diaphragm (substernal approach). Isthmus-diaphragm pulse wave delay was calculated as PWD=QV2 - Qv1, where Qv1 and QV2 represent the time delay between the ECG Q wave and the foot of the aortic velocity curve recorded, respectively, in the isthmus and near the diaphragm. The PWV was calculated as : PWV=L/PWD(m/s). L was the sternal length which was assimilated to the length of the descending thoracic aorta. We examined the relationship between various cardiovascular risk factors, such as age, gender, smoking, diabetes, lipid profile, LVH (left ventricular hypertrophy), and 24-hour ambulatory blood pressure, and PWV. Results : We observed a positive correlation between PWV and age, PWV and 24-hour ambulatory systolic blood pressure. We did not find a significant difference between PWV and other cardiovascular risk factors (sex, smoking, DM, LVH, and lipid) except age and 24-hour ambulatory systolic blood pressure. Conclusion : Determinants of aortic pulse wave velocity in patients with hypertension were age and 24-hour ambulatory systolic blood pressure.
