임신은 갑상선 기능 검사의 중요한 해석을 필요로 하며 임신 중 갑상선 기능 이상과 외부 바이러스성 감염 인자들의 항체의 존재는 태아 및 산모의 건강에 영향을 미치기에 임신에서 갑상선 기능의 선별적 평가가 요구된다. 본 연구에서는 임신기간 동안 정상 산모들의 선택적 산전 감염인자 검사 항목 중에서 갑상선 관련 인자와 바이러스성 감염 인자의 임신시기별 상호 연관성을 알아보고자 하는 후향적 단편 실태조사이다. 분석한 결과를 살펴보면, T3는 나이가 증가함에 따라 감소하고, 특히 HCV가 양성인 그룹에서 양의 유의성을 보였다(P<0.01). 또한 HIV가 음성이지만 임계치에 근접하거나 쌍둥이 임산부에서는 FT4가 유의한 증가를 나타냈다(P<0.05). TSH는 30대 연령에서 높게 분포하였으며, 다른 바이러스성 감염인자와는 통계적 유의성이 나타나지 않았다. 또한, TSH의 결과 값을 삼분위로 나누어 분석한 결과, FT4와 T3은 양의 상관성을 보였으나 TSH와는 음의 상관성을 보였다(P<0.05). 따라서 본 연구를 통해서 임신 중 산전검사인 갑상선 검사와 바이러스성 감염인자의 검사를 통한 임신 중 평가는 임신 경과시간, 감염인자의 노출상태 및 정량적 수치의 상태를 반영하여 이루어져야 할 것이며, 갑상선 관련 내분비 인자에 대한 산전검사의 유용성에 대한 평가의 보완이 이루어져야 할 것으로 사료된다.

This research is to study about the weight-change of a pregnant woman, conditions of the woman and an infant. The weight-change of a mother during pregnancy was observed and that was expressed as the basis on the body mass index of a mother before pregnancy. The effects of weight-changes on both the discomfort, complications of pregnant mother and the condition of an infant were also investigated. Thus we set a purpose that this study would help pregnant woman and an infant to maintain and enhance their health conditions by proper weight control through nursing mediation. This study was performed in a certain hospital of university in seoul from Feb. 1. 2000 to Mar. 31. 2000. We explained the purpose of this study to the hospital institution and obtained consent of investigation. 152 inpatients who were in condition from PA 37 weeks to PA 42 weeks were the subject of this study. The research materials were made through of question paper that inpatients make answer by themselves and investigation paper. The question paper was about general background, weight and height before pregnancy and discomfort of the physical degree. And the investigation paper was about parity, maternal weight(late pregnancy), high pregnancy, delivery method, hemoglobin level, Apgar score, fetal weight. Physical discomfort was measured using the implement made by Kim hae won(1996) (chronbach's ${\alpha}=0.85$). SPSS was used to do statistics for managing and analyzing data. The results of this study were like followings. 1. The mean value of gained weight during pregnancy was about 13.8kg within from 3 kg to 26 kg. Among 152 research candidates, the gained weight of 80(52.6%) candidates remained within an ideal range. But that of 37 candidates(24.3%) became less than the ideal range. Also that of 35 candidates(23.0%) became over than the ideal range. 2. In the investigation of the relation between the weight change of a pregnant woman and her condition, the scores to represent physical discomfort were middle in all candidates. And the physical discomfort of over weight-gained group was more than that of low weight-gained group, but there was no difference in statistics(F=0.234, p=0.791). The weight-changes of pregnant woman didn't have an influence with the high risk of pregnancy(F=0.509, p=0.477). Also, the weight-changes didn't have an influence on delivery method($x^2=3.825$, p=0.148). However, in the investigation of the relation between weight-change and hemoglobin level, the change of hemoglobin level was highest in over weight gained group(F=3.062, p=0.05). 3. In the investigation of the weight-change of pregnant woman and the condition of infant. the weight changes didn't have an influence on both 1 min Apgar score(F=0.157, p=0.855) and 5 min Apgar score(F=0.030, p=0.970) of infant. Also, in the investigation of weight-change of a pregnant woman and weight difference of a infant with Pearson Correlation Coefficient, the weight-change of a pregnant woman affected vastly the weight of a infant. It was also found that the more pregnant woman gained in weight, the more did gain weighty infants. This relation was in net proportion(r=0.256, p=0.001). In conclusion, these results suggest that the weight-changes during pregnancy in Korea women of these days are more increased than that of the past days and individual variation in weight-changes is very high. Also, these results suggest that the changed hemoglobin level of a mother and weight of an infant were meaningfully affected by the weight-changes of a pregnant woman during pregnancy. However, the physical discomfort of a pregnant woman, the high risks of pregnancy, the delivery method and Apgar score of an infant were not affected by the weight-changes during pregnancy. Because the recommendation suggesting the ideal weight-change, used this study, is basis on the subject of American women, therefore, these results also suggest the necessity of such recommendation which is subject to Korean women.

This study was designed to evaluate the changes and improvements in the Korean diet during the last thirty years (since independence in 1945), and to make recommendations for the improvement of their nutritional status, consequently contributing to the physical and mental welfare of the Korean people. The results and recommendations are as follows: 1. The total calorie and carbohydrate intake decreased by $8{\sim}12%$ in the 1970's, as compared with the 1940's and the 1950's. 2. The intake of calcium and vitamiu A increased $30{\sim}50%$ and $20{\sim}60%$ respectively in the 1960's and 1970's as compared with the 1940,s. But this intake level is still lower than the RDA values. 3. The vitamin C intake was somewhat higher in the mountainous and farming areas than in urban areas. 4. In the 1970's, the decrease of untriend intake due to seasonal variation was marked especially for protein, niacin, vitamin $B_1$, and vitamin C. 5. The consumption of protein foods (meats and legumes) increased in an amount of $15{\sim}36g$ per day. There was a marked increase in the intake of meat in farming areas and of milk in urban areas in the 1970's. This increased intake of animal proteins is a very desirable dietary change. 6. The cereal consumption was lowest in urban areal, but there was a general decrease in the intake of the cereal group in the entire area in the 1970's. For the farmers, the intake of cereal food decreased most, from 750 g to 576 g, but cereals still composed a high proportion of the entire diet. 7. Fruits and vegetables showed the highest intake for the urban people, as expected. For the whole area, this food group showed an increase of 8.7% in the 1970's, as compared with the 1960's. 8. The gradual ihcrease in the intake of the fats and oil group was a desirable dietary change. but the absolute amount was too low. 9. A 7% increase in height and a 9% incrrase in weight for growing children and adolescents was observed in the 1970's as compared with the 1940's, but several kinds of deficiency diseases, such as nutritional anemia and dental caries were still apparent in many areas. 10. To improve cur food life and to cope with food shortages faced in Korea, an efficient and nationwide nutrition education program should be implemented. This would maximize efficiency of intake from the limited food sources for a balanced diet. 11. As it is of utmost importance to provide growing children with a desirable physical, sccial mental, and especially nutritional environment, a well-planned and organized school feeding program should be practiced widely and efficiently. 12. Young mothers and pregnant women should be educated on the importance of their children's nutrition, especially for the critical fetal and infancy periods. 13. More thorough and continuous nutritional survey studies on the changes in dietary patterns for the entire nation should be pursued, evaluated and documented. This would Provide a good information guide for future nutritional study programs. 14. It is the nutritionistist's strong desire that national leaders, especially decision makers recognize the fact that improvement of the nutritional status of the People is one of the most economic and preventative ways of improving their physical and mental health. This is closely related to the economic development and strength of the nation.

The purpose of this study is to provide basic data regarding effective learning opportunities in childbirth education classes. Also analysis of the data indicates the optimum conditions for the welfare and improvements in the promotion of health in childbearing mothers. The results of this study are as follows; 1) The average age of the subjects in this study was 30.6 years and the total number of subjects was 58 pregnant women. The average number of children was one and 84.5% of the subjects were unemployed even though 63.8% of them held over bachelor's degrees. It was found that 22.4% of the subjects were living in an extended family. Also 61.5% of them were living with parents-in-law. The number of pregnancies were calssified as one, two, or three to nine times with the percentages of 58.7%, 22.4% and 18.9%, respectively. Further, 72.4% of the subjects had no abortion experience and 15.5% had one aborion experience. While 89.7% of the subjects planned to feed their babies with breastmilk, mixed feeding were used by only 22.4% of the sample. These data were collected at about 6 months after delivery. Thus one can see that a low rate of breastfeeding was common. 2) The length of one period of childbirth education is four weeks. It was found that 36.2% of the subjects participated in childbirth education only once, where as 13.8% participated four times and 19% of the subjects participated in this class more than four times. pregnant at least once. Further, 75.9% of the participants were participated in this education through their own will. Their motivation for participation developed through information, advertisement and posters which contained information on childbirth education. Those with unplanned pregnancies 92.9% participated after a suggestion by the nurses. The number of participants in terms of percentage according to the childbirth education contents can be classified as following. The most active participation was shown in preparation of delivery(77.6%), postpartrm management(56.9%) fetal development(37.6%) and physiology of pregnancy(17.2%). It was found that 75.9% of the subjects were willing to participate again if they were given a chance. The reason can be summarized as following: The content of the education is very helpful(47.7%). Scientific knowledge can be obtained through this program(20.5%). Participation helps in achieving psychological stability(9.1%). Participation enables one to establish a friendly relationship with other participants(6.8%) of the sample. 24.1% of the participants did not want to participate again. The reasons can be as following: They do not want another baby(42.9%). The first paricipation in childbirth education gave enough knowledge about childbirth(21.4%). Another reason for not want to participate again was because they had a cesarean birth(14.3%). Only 7.1% of them responded with a negative view. A response that they do not need childbirth education after their operation can be traced back to the general belief that childbirth education is the place where one prepares for natural birth through the Lamaze breathing technique. Of the subjects, 91.4% suggested that this program could be recommended to other childbearing mothers, because this program gave educational content along with psychological stability for childbearing women. Of the subjects 41.4% did not see any efforts towards the welfare of the baby, where as 88.2% did. Among the subjects 58.6% made some effort to eliminate the discomfort of labor by breathing and imagination and breathing and walking. Further 41.7% of the 24 subjects did not do anything toward the welfare of the baby, because they did have a cesarean section so that they didn't have a chance even though they had been educated about childbirth. Also 33.3% of the subjects did not do anything toward the welfare of the baby, because they lacked a willingness. After leaving the hospital, only 75.9% of the subjects did some exercises. The subjects who tried participate this program with their husband accounted for 20.7% of the sample. Interviewing with the subjects solved some of the uneasiness and. fear of delivery, increased self-confidence in parenting and active coping in the delivery process.

인공부화기 내에 종란이 입란하여 18일간 발생기를 거쳐 발육기로 이란을 한다. 발생기 동안 계태아 무게 손실은 곧 기실형성과 상관되며 적당한 기실 형성은 곧 건강한 초생추와 입란 대비 부화율과도 연결된다. 그러나 국내 부화장의 부화기에는 현재 무게를 측정하는 장치 없이 부화실장과 관계자의 경험과 발육기로 이란시 표준 무게 측정으로 결과적 측면을 습득하는 것이 현실이다. 그로 인하여 부화 중 조기 폐사, 약추, 병약한 초생추 발생이 빈번한 실정이다. 종란 중량 감소를 모니터링하는 것은 발육장치기 안에서의 무게 변화에 따른 병아리 품질과 부화율 성과를 얻는 데에 절대적으로 중요하다. 종란의 크기와 난각질, 노계 군에 따라 수분 손실은 각기 다르다. 발육기 안에서 무게 변화를 실시간 측정하고 그에 따른 환기 변화를 최적화하여 부화율의 증가를 기대할 수 있으며 부화 시 전체 무게의 10~13% 감소를 컨트롤할 수 있는 실시간 측정 시스템의 개발 필요성이 대두된다. 본 연구를 통한 시스템은 기존의 입란과 이란시 직접적으로 일회성을 체크하는 방식으로 발육 기간 내에는 계태아 수분 증발 측정 제어가 불가능하여 부화율에 영향을 못 미치는 시스템과 달리 아두이노 스케치 보드에 로드셀 4개를 병렬로 연결하고 실시간으로 휴대폰, 컴퓨터를 연결하기 위해 Hyper-terminal 프로그램을 이용하여 AT-command 명령어를 활용하여 정상적으로 연동하였다. 블루투스의 통신속도는 15200으로 설정하여 아두이노와 Hyper-terminal 프로그램의 통신 속도를 맞춰주었다. 실시간 모니터링을 하여 인공부화기 내의 계태아 무게의 변화를 육안으로 확인할 수 있도록 시스템을 설계하였다. 이와 같은 방법으로 종란의 부화율 상승 및 건강상태의 향상을 목표로 하였으며 실시간 모니터링으로 인하여 사용자의 편의성을 확대하고자 하였다.

본 연구는 임신기 동안 어미쥐의 철 섭취 수준이 모체의 철 대사지표와 산화적 스트레스 및 임신의 결과에 미치는 영향을 검토하기 위해 비임신쥐를 대조군으로 하여 수행하였다. 10주령 200 g 이상 된 암컷과 수컷 흰쥐를 1 : 1로 교배시켜 임신을 확인한 후, 비임신쥐 (대조군)와 임신쥐 (실험군)에게 식이 중 철 수준이 정상수준 (AIN-93G diet 수준, 35 mg Fe/kg diet), 고수준 (정상의 10배, 350 mg Fe/kg diet) 및 과잉수준 (정상의 30배, 1,050 mg Fe/kg diet)의 3가지 실험식이를 급여하였다. 임신 19일째 되는 날, 비임신쥐와 임신 쥐를 희생시켜 분석한 결과는 다음과 같다. 체중의 증가나 식이섭취량은 철 섭취 수준의 영향을 받지 않았고, 임신의 결과로서 태아의 수, 태아체중 및 태반무게도 철 섭취 수준의 영향은 받지 않았다. 헤모글로빈, 헤마토크릿, 혈청 철 농도 등의 혈액지표들은 철 섭취 수준의 영향은 받지 않았으나 임신에 의한 감소 경향을 보였다. 임신쥐의 철 섭취 수준의 증가에 따라 간과 지라 조직의 철 함량이 유의적으로 증가하였다. 또한 임신쥐의 간에서 페리틴 단백질 수준이 철 섭취의 증가에 따라 현저히 증가하였다. 산화적 손상지표인 지질과산화물 (MDA)은 철 섭취수준의 영향을 받지 않았고, 단백질 산화물 (protein carbonyls)은 비임신쥐와 임신쥐에서 모두 철 과잉 섭취군의 경우 유의적으로 증가하였다. 항산화효소 중에서는 철 과잉섭취군에서 간의 GPx 활성이 유의적으로 감소하였다. 결론적으로, 임신기 동안 어미쥐의 철 섭취수준의 증가는 어미쥐의 혈액지표와 임신의 결과에는 유의적인 영향을 미치지 않았지만, 간 조직 내 철 함량과 페리틴 단백질 수준을 유의적으로 증가시켰으며, 간 조직에서 단백질 산화물인 protein carbonyl 농도를 증가시키고, 항산화효소 중 특히 GPx의 활성 감소를 초래하였다. 또한 간 조직에서 세포사멸을 억제하는 중요한 인자인 Bcl-2 단백질 수준이 임신쥐에서 철 섭취의 증가에 따라 유의적으로 감소하였다. 이러한 영향이 철을 정상 수준의 10배 섭취한 군에서는 약하게 나타났으나, 30배 과잉으로 철을 섭취한 군에서는 유의적으로 차이를 보였다. 이 결과는 임신시 철 과잉 섭취의 해로운 영향이 지금까지 철 대사의 측정도구로 삼아왔던 혈액지표의 변화 보다는 체내에서 일어나는 조직의 산화적 스트레스의 증가나 조직 내 철의 축적 등에 보다 더 민감하게 반영됨을 알 수 있었다. 따라서, 철 과잉 섭취가 모체 뿐만 아니라 태생 조직의 산화적 스트레스에도 영향을 줄 수 있음을 시사하였다.
