  • The purpose of the study was to evaluate the educational content which had been given by midwifery training program. It was hoped that this result would help. It was sponsored by com-munity health worker plan effective health education. College of Nursing Ewha Womans University and The Korean Nurses Academic Society during the November 19 thru 24, 1979. It was carried out on July through on September 1980, and involved 22 community health workers. The results were as follows: 1. Most of the community health workers came from Seoul & Pusan areas and have been working at the hospitals. There were 31.82% of Head Nurses, 27.2% of Staff Nurses, 22.73% Nurse Supervisons, 13.6% of Nurse Directors and 4.5% of educational coordinator for Nurses. These participant had nurse-midwifery lincences by 63.64%. None of there had just midwifery lincences. 2, Age structures of the study population shows 31.82% of whom are.26-30 years and 22.73% of whom are 36. 40 years of age. This shown that seniority proportion is higher than the younger. There are 31.82% of 1-5 years, 27.27% of 6-10 year and 11-15 years, respectively by work career. 3. There are 54.55% of the institutions have opened their own midwifery training course for their nursing staff members. Because of lack of the facilities, shortage of instructors, and problems of administrative process. 4. According to the institution which opened for midwifery training courses, the participant was responsible for “midwifery”“Infant care”“MCH”“practice of midwifery”“Nursing adjustment”and“F. P.”5. During the midwifery couse, there were 8 institution who used the textbook and 4 institution who did not. Least of there referned to content matinals which was given by the sponsored. 6. There are 7 insititues who kept their training courses with other professional helps such as physicians., professiors and nurses. Some problems are pointed out by respondents such as“conflict with residents”“poor suportive administration”and“lake of manpower”. 8. The participant showed that they learned new knowledge as trends during this programs for there quality work so it need (one or twice times) a year. But they suggested that it needed more emphasis on the“maternal health care”and“role of the nurse-midwifery”. 9. The analysis of the results are as follows within the 6 areas which are given by the sponsored: There are highest ranks between“basic theory & family planning”“role of midwifery & nursing practice”. In the prenatal care the highest rank ware related to“health risk”on“idenify of risk symtoms”. In the health care areas which related to delivery, the responsers were related to“general conditions”or“high risk criteria”. In the health care area which related to high risk maternity care. In the neonatal health care, the highest rank was related to”health assessment of normal infant”. In the infant health care the responses was related to“abnormal symptoms”and“risk symptoms”. Actually, the participants show that they are more interested in“role of midwifery”“health assessment”and “high risk maternity care”are which emphasised on health promotion, health maintenance & disease preventive. 1) The midwifery training program need higher education for midwifery on a regular basis. 2) Within the open institution of midwifery training program, the nurses must be supported by their own institution and administry of social welfare must give systematic support. Also non-open institution must be open very soon. 3) All health workers including the residents & other workers, must cooperate for their phased common good of impovement of the maternity health. 4) Administration agonies & education institutions must provide the curriculum facilitis and administration systems which are needed for training of nurse-midwifery.

  • Purpose: The goal of this study was to compare the efficacy of oral 25% dextrose treatment or/and pacifier for analgesia in healthy newborns during intramuscular injection of a hepatitis B vaccine. Methods: A prospective, randomized, partially blinded, clinical trial was performed in 132 healthy newborns. They were assigned randomly to 4 treatment groups: control group (2 mL distilled water), dextrose group (2 mL 25% dextrose), pacifier group, dextrose+pacifier group (pacifier coating with 25% dextrose) during intramuscular injection of hepatitis B vaccine. For all groups, Neonatal Infant Pain Scale (NIPS), Neonatal Facial Coding System (NFCS), Premature Infant Pain Profile (PIPP) scores were evaluated before the injection, during the injection, and at 2 minutes after the injection. Pain scores were compared among the 4 groups. Results: Maternal and neonatal characteristics were similar among the 4 groups. 25% dextrose treatment led to lower NIPS pain scores during injection (6.4${\pm}$0.9 vs. 5.5${\pm}$1.7, P=0.01) and after injection (1.6${\pm}$2.0 vs. 0.6${\pm}$0.9, P=0.01) and NFCS pain scores after injection (1.5${\pm}$2.3 vs. 0.7${\pm}$0.8, P=0.04) than control group. The number of neonates who feel the pain (indication of scores: NIPS${\geq}$4, NFCS${\geq}$3) decreased (9 (23.1%) vs. 0 (0%), P=0.04 via NIPS, 7 (17.9%) vs. 0 (0%), P=0.02 via NFCS). However, all treatment groups did not decreased PIPP scores, compared with the control group. Conclusion: Oral 25% dextrose is effective than distilled water or using pacifier with or without 25% dextrose in reducing pain during intramuscular injection of hepatitis B vaccinations. Further study based on this preliminary study need about nonpharmacologic management of pain in newborns.

  • Purpose : Cri-du-Chat syndrome (CdCs) is a rare but clinically recongnizable condition with an estimated incidence of 1:50,000 live births. The clinical characteristics of the syndrome include severe psychomotor and mental retardation, microcephaly, hypertelorism, hypotonia, and slow growth. Also the size of the chromosome 5p deletion ranges were known from the region 5p13 to the terminal region. In this study, we report the spectrum of 5p deletion in Korean 20 pts. with CdCs and genotype-phenotype associations in CdCs. Methods : In order to delineate genotype-phenotype correlation, molecular cytogenetic studies including GTG banding and clinical characterization were performed on Korean 20 pts with CdCs including parents. CGH array and Fluorescence in situ hybridization (FISH) analysis were used to confirm a terminal deletion karyotype and map more precisely the location of the deletion breakpoint. Results : Molecular analysis of the spectrum of 5p deletion revealed 9 pts (45%) with a del (5)(p14), 7 pts. (35%) a del (5)(p13), 3 pts. (15%) a del (5)(p15.1) and 1 pt. (5%) a del (5)(p15.2) in 20 pts with CdCs. 4(20%)pts were identified to have additional chromosome abnormalites of deficiency and duplication involving chromosomes of 6, 8, 18, & 22. Parental study identified 3 familial case (2 paternal and 1 maternal origin) showing parents being a balanced translocation carrier. And the comparison study of the deletion break points among these 20 pts. with their phenotype has showed the varying clinical pheno-types in the CdCs critical region. Conclusion : The characterization of 5p deletion including parental study may help to delineate the genotypephenotype correlation in CdCs. Also these molecular cytogenetic analyses will be able to offer better information for accurate genetic diagnosis in CdCs and further make possible useful genetic counseling in pts. and family.

  • This study was performed to determine sequences of the mt DNA D-loop region, including $tRNA^{Pro}$ and $tRNA^{Pre}$ and to analysis sequence variation polymorphism in Korean cattle. The resulting sequencies were compared with previously published sequences for other cattle breeds(GenBank J01394). The PCR was used to amplify an 1142bp between nucleotides 15061 and 404 within the D-loop region of mt DNA using specific primers. Korean cattle showed 24 polymorphic sites by nucleotide substitutions and insertions of single base pairs. About 50% of polymorphic sites were found in positions 16042 to 16122 with the most variable region. Among these polymorphic sites, variations at 16055, 16230 and 16260 bp were detected as new sequence variants in Korean cattle. These specific polymorphic sites have not been reported in the Japanese black cattle and European cattle. Therefore, mt DNA variants in the D-loop region may be used as genetic markers for specifying Korean cattle. The frequencies of positions 169, 16302, 16093, 16042, 16119 with a high level of sequence polymorphism were 0.81, 0.56, 0.56, 0.50 and 0.43, respectively. In comparison of genetic distances, Korean cattle showed the more closely to European cattle as Bos taurus than Bos indicus such as African and India breeds. In conclusion, these mt DNA sequence polymorphisms in the D-loop region for Korean cattle may be useful for the analysis of cytoplasmic genetic variation and associations with economic important traits and genetic analysis of maternal lineage.

  • This study was undertaken to observe relationships between patterns of feeding, supplementary-feeding and various maternal, family, and socioeconomic charactereistics in Hae Cheog Apartment area in Cheongdam-dong, Kangnamku, Seoul on July 2 to 12 in 1982. The results were based on a questionnaire from 179 mothers who have the last-born child under two years old. Results were as follows: 1) In socio-demographic characteristics, most of mothers were 25 to 30 years old and 52.0% of index children were under 6 months old. About 56.0% of families were the salaries and 47.0% of them earn over 500,000 won a month. 40.8% of mothers were college graduates and 81.6% of mothers had no occupation. 2) 89.4% of mothers received prenatal care in pregnancy of the index children and mothers who have delivered the child in medical institute were 88.3%. Mothers who recieved education of breast care and feeding technique through prenatal care were 22.4%, 31.8% respectively. 3) In the feeding method, 44.1% of mothers took the breast feeding, 24.0% of them chose the artificial feeding, and 20.7% of them chose the mixed feeding. Mothers who changed the-method from breast feeding to artificial feeding were 10.6% and only 0.6% of mothers changed from artificial feeding to breast feeding. 4) According to the questionnaire, 37 mothers have already finished lactation (no relation with. the beginning of weaning food). In breast feeding, one mother has lactated for $4{\sim}6$ months, one has lactated for $7{\sim}9$ months, four have lactated for $10{\sim}12$ months, and seven have. continued the lactation over 12 months. In artificial and mixed feeding, as the same phenomenon, most of mothers have lactated for more than 12 months. 5) The reasons for feeding method were as follows: In breast feeding, 64.6% of them took the method because they thought the breast milk nutrious, in artificial feeding, 34.9% of them chose it because they had occupation and in the mixed feeding, 67.6% of mothers took the method because of lack of their breast milk. In the case of changing the method from breast feeding to artificial feeding, 42.1% of them answered that they had to change the method because of lack of breast milk. 6) In most of cases, the 4th month was the proper period to begin the weaning food and 32.5% of breast feeding children and 27.6% of artificial feeding children began the weaning food in 4th month. After 4th month, there was no difference between breast feeding and artificial feeding in the beginning of weaning food. 7) In the matter of menstruation, 29.8% of mothers who had breast feeding started their menstruations in 3 months and the rest of them delayed until 12 months. 40% of mothers who had artificial feeding began to menstruate after 2 months and all the rest started within 5 months. 8) The birth interval between the index child and next new child (would-be-born): In breast feeding, the interval of $18{\sim}24$ months had a majority as 50.0%, and in the artificial feeding, the interval of over 24 months marked 66.7% of them. It was analyzed that the birth interval of artificial feeding was wider than that of breast feeding. 9) In the desirable number of children, the mothers who had breast feeding wanted two sons and two daughters as proper children. Those who want two children in disregard of the sex (son or daughter) were 89.3% of breast feeding, and 80.0% of artificial feeding respectively. Mothers who had breast feeding wanted two children rather than one child. 10) In the family planning practice, the rate of practice were 41.9% in breast feeding, and 58.1% in artificial feeding respectively. In the case of breast feeding, the using rate of family planning practice in men was higher than in women.

  • Breslau's report on the two stillbirths induced by illuminating gas poisoning made many investigators explore the hazards. of carbon monoxide(CO) poisoning to pregnancy. The pregnant woman, her fetus, and the newborn infant have been identified to be particularly vulnerable to CO even in low concentration. Several factors, such as placental barrier, membrane resistance of maternal and fetal red blood cells etc., were considered to be related to the delayed elimination of CO from fetus. Slower elimination of CO from fetus than from mother was confirmed in several in vivo studies. But there are few studies which have confirmed the difference of carboxyhemoglobin (HbCO) dissociation in adult and fetal bloods. Author investigated the effects of hemoglobin itself on the elimination of CO from mother and fetus. By observing the difference of CO dissociation from adult and fetal hemoglobin at the various partial pressures of oxygen, the author tries to suggest the base of the proper treatment measure for the CO poisoning of pregnant woman and newborn infant. The results were as follows: 1. The total hemoglobin amounts of adults and fetal bloods were $16.1{\pm}0.50gm%\;and\;15.7{\pm}0.32gm%$, respectively. The fetal hemoglobin proportions in adult and fetal bloods were $1.2{\pm}0.15%\;and\;72.7{\pm}3.01%$, respectively. 2. Adult and fetal bloods saturated by CO to 100% HbCO were exposed to ambient air$(21%\;O_2),\;100%\;O_2\;and\;3\;ATAO_2$. After 30 minutes exposure, the HbCO saturations of adult blood were 96.7%, 70.9%, and 52.8%, respectively, and those of fetal blood were 98.5%, 76.1%, and 62.2%, respectively. HbCO dissociation was proportional to the partial pressure of oxygen and the most marked dissociation was shown under 3 ATA $O_2$, HbCO dissociation of fetal blood was slower than that of adult blood in all conditions. According to the above results, it is possible that CO poisoning make more serious damage to the fetus and newborn infant than to the adult due to the delayed dissociation of HbCO. Thus in the treatment of CO poisoning of pregnant woman and newborn infant, hyperbaric oxygen therapy seems to be the most eflective treatment measure, but the duration of hyperbaric oxygenation should be lengthened accordingly.

  • To measure the birth registration rate and the validity of birth registration data in rural area, all of the 4,014 married women under 49 years of age who had not been sterilized in Gunwee county of Kyungpook province were followed by Myun health workers for 2 years from April 1, 1985 to March 31, 1987 and 766 births were detected. All of the birth registration records of Myun offices were reviewed on September 30, 1987 and 944 births which occurred within the above mentioned period were found. Actual birth date obtained by follow-up study were compared with the birth date on registration card. Among 766 births detected by follow-up study,576 births(75.2%) which were reported within 6 months after birth were ascertained on the official registration records and 96 births(12.5%) were not found on the records although mother stated that the birth was registered. The registration rate within legal due date was 61.3% among 576 births detected by follow-up study and also ascertained on the official records. The registration rate within legal due date was lower in mothers under 20 years of age and above 35 years and in mothers who had only primary education. It was decreased as the birth order increased. The registration rate was higher in births occurred from October to March than births occurred from April to September. All of the births of 7 neonatal deaths were not reported. The registered birth date was consistent with the actual birth date in 78.0%. Birth date on record was earlier than the actual birth date in 6.8% and later in 15.3%. The consistency rate was lower in mothers above 35 years of age(54.5%), and in infants of 4th birth order and above(56.3%). The rate was increased as the maternal education level increased. The rate of boys was higher than that of girls. A higher percentage(17.4%) of infants born in March was registered with earlier date than the actual birth date and most of these registered birth dates were lunar calendar date. This might be related with the age for entering the primary school. The study findings revealed that the birth registration rate within legal due date and accuracy of report have been increased in recent years, but the infant mortality rate derived from the birth registration seems to be very inaccurate. It is suggested to let the medical personnel who delivered the baby report the birth by mail directly to the current address of parent while infants delivered at home without professional attendant may comply with the present registration system.

  • Objectives : This study aimed to investigate the toxic effects of chromium (VI) on the placental function and reproduction in rats. For the study, the placental prolactin-growth hormone (PRL-GH) gene expression, placental trophoblast cell differentiation and reproductive data were analyzed. Methods : The pregnancies of F344 Fisher rats were checked by the presence of a copulatory plug or sperm in the vaginal smear, which was defined as day 0 of the pregnancy. Pregnant rats were divided into the three groups. The control group was given tap water (chromium level < 0.001 ppm) and the remaining groups were given 250 or 750 ppm of chromium (VI) [as potassium dichromate], from day 7 to 19 of the pregnancy. Rats were sacrificed at days 11 and 20 of pregnancy. The mRNA levels of PRL-GH and Pit-1a and b isotype genes were analyzed by Northern blot hybridization and reverse transcription-polymerase chain reaction (RT-PCR). The hormonal concentration was analyzed by radioimmunoassay, and the differentiation of placental trophoblast cells were observed by histochemical studies. Reproductive data, such as placental and fetal weights, pregnancy period, and litter size, were surveyed at day 20 of pregnancy and after birth. A statistical analysis was carried out using the SAS program (version 8.1). Results : The mRNA levels of the prolactin-growth hormone (PRL-GH) family of genes were dose dependently reduced by chromium exposure. The mRNA levels of Pit-1a and b isotype genes that induce the expression of the PRL-GH family of genes were also reduced by chromium exposure. The PRL-GH hormonal concentration in the rat placenta, fetus and maternal blood were decreased by chromium exposure. In the middle stage of pregnancy (day 11), a high dose of chromium suppressed the differentiation of spongiotrophoblast cells that secret the PRLGH hormones. In the last stage of pregnancy (day 20), a high dose of chromium induced apoptosis of placental cells. Reproductive data, such as placental and fetal weights, litter size, were reduced, but the pregnancy period was extended in the group exposed to chromium compared with the controls. Conclusion : Chromium (VI) disrupts the ordered functions of the placenta, which leads to reproductive disorders in rats.

  • The objectives of this study are to identify health behaviors and health problems. and the relations between health behaviors and health problems of female workers in the retail business. The number of subjects were 200 female workers of 6 department stores in Seoul and Kyonggi area, whose jobs last more than 6 months as retail employees. The data was collected during 2 months from July 1 to August 30, 1998. The Cornell Medical Index Health Questionnaire(CMI) was used to measure their health problems, while health behaViorn were investigated in terms of 'smoking', 'alcohol', exercise', 'diet', and 'sleeping'. The data were analyzed with frequency. percentage, t-test, ANOVA test, and $X^2-test$ by SPSS PC+ program. The results of this study are as follows: 1. Out of health problems. Digestive symptoms occupied the highest percent number. nervous ones the second and cardiovascular ones the third among physical health problems of retail female workers. The most frequent mental health problem was 'adequacy' and the next, 'tension' and 'anger', 2, Health problems according to general characteristics of subjects were shown that the younger or the unmarried complained more than the older or the married, especially in the items of 'eye and ear', 'respiratory system', 'cardiovascular system', 'digestive tract', 'nervous system', 'adequacy', and 'depression'. The longer working duration they have had, the more they complained of 'respiratory system' and 'adequacy'. The lower academic careers complained of 'nervous' than the higher ones with statistical significance. 3. The analysis of daily health clinic notes showed that respiratory complaints were the highest percent, successively followed by digestive tract, nervous one, external injury, musculoskeletal system, urinary-reproductive system and others. 4. The level of their health practice was generally low in smoking, diet habit and alcohol intake, exercise, sleeping, very low especially in smoking, diet, alcohol intake, and exercise among them all. 5. Present smokers and ones with past experience complained of physical and mental health problems of 'respiratory system', 'digestive tract', 'skin', 'nervous', 'urinary-reproductive system', 'fatigability', adequacy', 'depression', 'anxiety', 'anger' and 'tension', than non smokers, with statistical difference. Workers without having breakfast and with irregular diet had more complaints on 'digestive tract', 'adequacy' and 'tension', than those who had regular dietary habit. The less the subjects slept, the more they complained of eye and ear, cardiovascular system. The subjects who drank alcohol complained more digestive problem. However, whether they exercise or not did not affect physical and mental health problems in a significant manner. 6. The subjects' age and marital status were statistically significant relating to health behaviors, as the younger or unmarried recorded a low level of health practice in smoking, drinking, dietary habit. Based on the results, the suggestions are made as follows: 1. Health education program on smoking, alcohol intake, diet habit is needed to improve health problems and health behavior of female retail workers. 2. The unmarried workers of late teen and twenties, who are transitional period from teenagers to adulthood are important targets for health promotion program especially for maternal health. 3. Better working environment with sufficient time and facilities for workers to relax is required to promote female sales workers' health. 4. Further research is required to identify the relation between workers' visual fatigue and intense lights for the display of goods.

  • For the comparative study of protein patterns of the sera of pregnant women, the protein in sera of normal male subjects, non-pregnant women, pregnant women and women delivered of children were analyzed by using the methods of SDS/polyacrylamide gel electrophoresis, two-dimensional electrophoresis and amino acid analysis. The results were as follows: 1. When the protein patterns of sera in normal male ranging from 10, 000 to 110, 000 daltons were compared to non-pregnant women by SDS/polyacrylamide gel electrohporesis, their protein patterns were same each other numerically but bands 3(22, 000 dalton) and 6(39, 000) were less in male than in non-pregnant women quantitatively. When the protein patterns in the pregnant women in which serum were collected two week intervals were compared with non-pregnant women, there was increased or decreased in several bands quantitavely. The protein patterns of sera in pregnant women were compared with those of non-pregnant women; band 3(22, 000) showed similar patterns each other until the 16th week but the quantity of protein was decreased continously from the 18th week to the third trimester of pregnancy. Contary, bands 4(24, 000), 9(69, 000), 10(70, 000), 12(80, 000), 14(86, 000), 15(91, 000) and 16(94, 000) were gradually increased in quantity from the begining of gestation, and band 7(51, 000) was increased until the 32th week of gestation only but somewhat decreased after this time. The quantities of bands 12(80, 000), 15(91, 000) and 16(94, 000) were relatively increased when the protein patterns of delivered women were compared with those of the third trimester of pregnancy. Women who were dilivered female children showed more increase in bands 4(24, 000), 7(51, 000) and 10(70, 000)than one who were delivered male chilren. 2. When the protein patterns of sera in normal males were compared with those of nonpregnant women by two-dimensional electrophoresis, three spots of spot a group were not appeared in the males and the spot c group in the males was less than in the non-pregnant women. In the pregnant women, albumin was significantly decreased during the 10-12 week of gestation but recovered after these times. And spot f(70, 000) was decreased in the 10th week of gestation but increased from this time. 3. Glutamic acid, lysine, aspartic acid, leucine and valine in pregnant women were large in quantity while methionine, isoleucine and glycine were small in quantity by amino acid analysis. The total amino acids were increased remarkably in the second trimester of pregnancy but began to decrease in the third trimester of pregnancy. As mentioned, this present paper deat with that proteins which consist of maternal serum were increased with specific period in pregnancy and that the change of characteristic protein patterns were identified in the serum protein of each trimester in the pregnant women. And furthermore, the study should be preformed for the sex-identification of a fetus in the early pregnancy.
