Association of maternal iron status with birthweight at third trimester in pregnant women

To investigate the association between maternal iron status at the third trimester and fetal birthweight, maternal serum iron, ferritin, total iron-binding ca- pacity (TIBC), and complete blood count values were measured at 36-weeks gestation. Delivery database on mothers who delivered babies at Chungbuk National University Hospital between January 2008 and March 2013 was extracted. A total of 353 uncomplicated term babies were analyzed using hierarchical regression and ANCOVA. Maternal age (standardized regres- sion coefficient β=0.115, P<0.05), height (β=0.108, P<0.05), BMI (β=0.210, P<0.001), and gestational age (β=0.298, P<0.001) were significantly associated with birthweight. However, birthweight was not associated with maternal iron parameters. After adjusting for maternal age, height, BMI, and gestational age, babies born to mothers with lower mean values of hemoglo- bin, hematocrit, and serum ferritin were heavier than those born to mothers with higher values. Babies born to lower hemoglobin (11 g/dL) mothers were heavier than those born to higher hemoglobin (12 g/dL) moth- ers. However, birthweight was not significantly differ- ent between mothers with 10 g/dL or 13 g/dL of hemo- globin. Comparing birthweight according to 30 ug/dL of serum iron, 360 ug/dL of TIBC, 15 ng/mL of serum ferritin, and 10% transferrin saturation, babies born to mothers of the lower group were heavier than those born to mothers of the higher group. Therefore, ma- ternal serum iron status at the third trimester seems to not be associated with birthweight.
Table - Driven Code Generation 방법을 이용한 Assembly Program의 Translation에 관한 연구
신영옥,김대식,유재우,송후봉 한국정보과학회 1985 한국정보과학회 학술발표논문집 Vol.12 No.2
본 논문은 table-driven code generation방법을 이용해서, 기종이 서로 다른 기계사이의 assembly language program 을 변환 시키는 한 방법에 대해서 기술하였다. 본 Translation 방법은 3개의 과정으로 구성되어 있는데, 즉, 한 기계의 assembly program을 입력으로 받아 중간형태인 Internal Representation(IR) 로 변환하고, optimize 된 형태로의 sub-stitution 한후, code generation 과정을 거쳐 타 기종의 assembly langua-ge program으로 변환으로 방법을 제시하였다. 본 논문에서는 이러한 assembly language program을 변환 시키는데 필요한 Translation Model 의 제반 사항에 대해 고찰하고, IR의 기본 형태와 성격에 대해서 묘사하며, Translation 의 핵심부분이 되는 Glanville 의 Table-Driven Code Generation 방법을 소개 하였으며, 이를 이용한 translation 방법의 구현 및 실험 결과에 대해 기술하였다.
