Mitral inflow velocity recorded by Doppler echocardiography has been widely used to evaluate left verrπicular diastolic function but it is affected by other factors. The mitral annulus velocity profile during diastole may provide additional information about left ventricular diasto1ic function. π1Is study was performed to assess the c1inical utility of mitral annulus velocity measured by Doppler tissue imaging (DTI) in the evaluation of left verrπicular diasto1ic function. Mitral annulus velocity during diastole was measured by DTI in 38 consecutive patients undergoing cardiac catheterization in whom mitral inflow velocity and time constant of isovolumic relaxation (tau) as well as mitral annulus velocity were measured simultaneously. Peak early diastolic mitral annulus velocity (r = -0.56, p < 0.01) and the earlyjlate ratio (r = -0.46, P < 0.01) correlated well with tau. When the combination of normal mitral inflow variables with pr이l onged tau (> or = 50 ms) was classified as pseudonormalization, peak early diastolic mitral annulus velocity < 8.5 cmfs and the earlyjlate ratio < 1 could identify the pseudonormalization with a sensitivity of 88% and specificity of 67%. Mitral annulus velocity determined by DTI is a relatively preload-independent variable in evaluating diastolic function.

이 연구는 감정노동과 여성간호사의 생식건강과의 관계를 확인하고 감정노동이 생식건강에 미치는 영향을 알아보기 위하여 시도되었다. 연구대상은 병원에 근무하는 간호사 259명으로 하였으며 구조화된 설문지인 감정노동 측정도구와 생식건강 측정도구를 사용하여 측정하였다. 자료분석은 SPSS 17.0 Program을 이용하였으며 감정노동과 생식건강의 관계 및 생식건강에 미치는 영향을 파악하기 위하여 피어슨 상관계수와 회귀분석으로 분석하였다. 본 연구의 결과는 다음과 같다. 여성간호사의 생식건강은 연령, 학력, 교대 근무에 따라 차이가 있었으며 감정노동과 생식건강은 유의한 정의 상관관계로 감정노동이 증가할수록 생식건강의 위험이 높아짐을 알 수 있었다. 여성간호사의 생식건강에 영향을 미치는 요인은 감정노동이었으며 생식건강에 대한 설명력은 13%이었다. 이상의 연구결과 감정노동이 여성간호사의 생식건강에 중요하게 영향을 미치는 요인임을 알 수 있었다. 따라서 여성간호사의 생식건강 증진을 위해 향후 감정노동을 관리할 수 있는 중재프로그램의 개발이 필요할 것이다. This research has been carried out to examine the effects of emotional labor on female reproductive system and the influence factors. In doing so, 259 nurses from hospitals have been given with structured questionnaires including emotional labor and reproductive system health measurements. To analyse collected data, SPSS 17.0 program has been employed. Further, the effects of emotional labor on reproductive system have been analyzed through Pearson"s Correlation Coefficient and Stepwise multiple Regression. The results are as follows. There have been differences in the state of female reproductive system according to age, education and work rotation. In addition, a positive correlation between the two factors that the risks of reproductive system increases with increase in the level of emotional labor The influence factors for female reproductive system are age, and emotional labor. Among them, emotional labor has been found to be most influential. The explanatory power of these variables has been 13%. According to these findings, emotional labor has been found to influence female reproductive system mostly. Therefore, there needs to be mediate program for managing to improve the state of female reproductive system.
