목적: 임신 중 합병증이 없었던 단태 산모에서 만삭 질식 분만으로 태어난 건강한 정상 신생아의 제대 동맥혈 가스 분포를 알아보고자 하였다. 연구 방법: 1995년 3월부터 1998년 6월 까지 충북대학교병원 산부인과에서 태어난 신생아에서, 분만 즉시 태반측 제대 동맥에서 혈액을 채취하여 pH를 비롯한 혈액 가스(PaCO2, PaO2, actual bicarbonate)를 측정하였다. 그 중에서 산모는 과거에 중대한 질병을 앓은 적이 없고, 정상 단태 임신으로 임신 중에 별다른 합병증이 없었으며, 만삭에 두정위 질식 분만으로 출생한 신생아는 임신 중 성장이 적절하였고, 어떠한 선천성 기형도 없으면서, 출생 후 1분과 5분 아프가 점수가 모두 7점 이상인 경우로 제한하였다. 그래서 총 457명의 건강한 신생아의 제대 동맥혈 가스분포를 분석하였다. 결과: 제대 동맥혈의 가장 낮은 pH 값은 7.04이었고 가장 높은 값은 7.51이었다. 10 퍼센타일은 7.23이고 90 퍼센타일은 7.39인 한편 중앙값(median)은 7.31이었다. 7.20 미만은 5%에 해당하였다. PaCO2의 값은 25.0mmHg에서 67.2mmHg의 범위였으며 중앙값은 44.1mmHg이었다. PaCO2의 값의 10 퍼센타일은 33.4mmHg인 반면 90 퍼센타일은 56.5mmHg이었다. 제대 동맥혈의 PaO2의 값은 4.6mmHg에서 36.9mmHg의 범위였다. 중앙값은 17.3mmHg인 한편 10 퍼센타일은 11.5mmHg이었고 90 퍼센타일은 24.2mmHg이었다. Bicarbonate의 수치는 13.2mmol/L에서 30.0mmol/L의 범위에 있었으며 10 퍼센타일은 18.4mmol/L이었고 90 퍼센타일은 26.5mmol/L이었으며 중앙값은 22.6mmol/L로 나왔다. 결론: 본 연구에서는 합병증이 없었던 만삭 단태 임신부에서 정상적으로 질식 분만된 건강한 신생아 457 명을 대상으로 하여 제대 동맥혈 가스 분석을 함으로써 건강한 정상 신생아의 혈액 가스 값의 정상역을 제시하였다. Objectives: To study the distributions of pH and gas values in umbilical arterial(UA) blood of normal newborns following uncomplicated pregnancies and vaginal births. Methods: In 457 consecutive normal term infants who were born between March 1995 and June 1998, we examined the UA pH and blood gas values obtained immediately following delivery. Maternal inclusion criteria were defined as an uncomplicated singleton pregnancy and a normal full term spontaneous vaginal delivery. And also neonatal inclusion criteria were defined as a normal intrauterine growth appropriate for gestational age without any malformations and Apgar score of 7 or more at both one and five minutes after birth. Umbilical artery blood samples were collected at each birth and were evaluated for pH, carbon dioxide pressure (PaCO2), oxygen pressure (PaO2) and actual bicarbonate. Results: Histogram of UA pH value resemble normal distribution curve. The lowest UA pH was 7.04 and the 10th percentile value was 7.23. The median UA pH was 7.31 and 5% was below 7.20. The lowest UA PaO2 was 4.6mmHg and the 10th percentile value was 11.5mmHg. The highest UA PaCO2 was 67.2mmHg and the 90th percentile value was 56.5mmHg. The lowest bicarbonate value was 13.2mmol/L and the 10th percentile value was 18.4mmol/L. Conclusion: The distributions of the UA pH and gas values of the collective of normal newborns were illustrated. None of the UA pH was below 7.0.

Resent domestic construction projects require professional management from the early stage to design, construction, maintenance management stage to achieve their business goal efficiently. Apartment construction in public sector has been leading quantity growth for the past 40 years by improving house supplement ratio. But the necessity of changing for the existing management method has been emerged by the needs of times and developed construction technology. By this time, public sector has been applying various ordering and management methods. There are general(including others) ordering methods and Turn-key(Design-Build) in business methods, and self-management district, responsible-inspection district, CM(Construction Management) inspection district in field management methods. But achievement analysis about various business methods and systematic effort to solute problems are still not enough. So, this study will analyse business performance stage and characters in all types which can compare practically according to each of management system about construction management methods applied in public sectors and suggest the improving direction about proper business management application according to upcoming business types.

Background: The purpose of this study was to describe the use of complementary and alternative medicine (CAM) services by Korean elite collegiate athletes and to examine the factors influencing the utilization of CAM, or Korean Medicine (KM). Methods: Students in Korea National Sport University (KNSU) enrolled and in training during August to December 2017 completed the survey. Data from the survey was analyzed through path analysis. Results: Students who were training in the Department of Physical Education, KNSU (n = 624, 70% males, mean age 21.3 ± 1.2) participated in this study. 15% of the respondents chose KM clinics for sports injuries, a higher rate than that of the general population, and 44% of KM interventions involved acupuncture. In the path analysis, sports injuries were positive predictors for utilization of medical services and the perception of KM, and KM utilization and the perception of KM were positive predictors of the willingness to receive KM treatments. Conclusions: The use of KM such as acupuncture was relatively high in elite collegiate athletes. The perception of KM and willingness to receive KM treatments were mediated by previous KM experiences. A higher accessibility towards KM treatments are necessary.

Objective: This study was conducted to evaluate changes in nutritional value and in situ dry matter (DM) degradability of oak and pine wood before and after steam-digestion process (60 min/160℃/6 atm) and feeding effect of the oak roughage on performance and behavior of Hanwoo steers. Methods: Chemical composition and tannin concentration were analyzed for oak and pine trees before and after the pretreatment. In situ DM and effective degradability of these samples were assessed using a nylon bag method. In vivo trial was performed to estimate animal performance and behavior, using steers fed total mixed ration (TMR) diets containing 0% (control), 25% (OR-25), and 50% (OR-50) of the oak roughage. Eighteen steers were allocated into nine pens (2 steers/pen, 3 pens/treatment) for 52 days according to body weight (BW) and age. Results: By the steam-digestion treatment, the neutral detergent-insoluble fiber was decreased from 86.5% to 71.5% for oak and from 92.4% to 80.5% for pine, thereby increasing non-fiber carbohydrate. In situ DM degradability of treated oak reached 38% at 72 h, whereas that of untreated oak was only 11.9%. The 0 h degradability of the treated pine increased from 5.9% to 12.1%, but the degradability was unchanged thereafter. Animal performance including BW, average daily gain, DM intake, and feed conversion ratio was not different among control and oak treatments. No differences were detected in animal behavior such as lying, standing, rumination, drinking, and eating, except walking. Walking was higher in control than oak treatments with numerically higher eating and lower lying times, probably due to bulkier characteristics of rice straw in the diet. Conclusion: This study demonstrates that the oak roughage can be substituted for 50% of total forage or 100% of rice straw in TMR diets at early fattening stage of Hanwoo steers.
