Purpose : Infantile colic is one of the most commonly encountered problems, characterized by excessive crying in apparently healthy young infants within the first 3 months of life. It is commonly assumed that the infant with colic has distress and possible pain. In recent investigations, it has been found that sucrose has an analgesic effect in newborn infants. The purpose of this study is to examine if sugar solution as sucrose also has an analgesic effect on infant colic. Methods : This prospective randomized, double-blind placebo controlled study examined healthy term infants aged 4 to 12 weeks with colic. A total of 40 infants were randomly assigned into two groups who visited Daedong Hospital from June 1999 to June 2001. Each group received sugar solution or sterile water. All data from parental diaries and interviews were recorded and analysed blindly. Results : The daily crying time and the colic improvement score were significantly better in sugar solution group as compared with the control(P=0.019, 0.045). No significant differences were noted between groups regarding the number of night wakenings(P=0.173). Conclusion : We conclude that sugar solution has an analgesic effect on infantile colic.

Purpose: Infants aged ≤90 days with fever are susceptible to severe infections. This study aimed to analyze the clinical features of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in this particular age group. Methods: Infants aged ≤90 days who were diagnosed with coronavirus disease 2019 (COVID-19) and hospitalized between March 1, 2020, and May 1, 2022 were included. Medical records of patients were retrospectively reviewed. Results: A total of 105 infants with COVID-19 were included; 27 (25.7%) neonates aged <28 days, and 48 (45.7%) and 30 (28.6%) infants aged 28-59 days and 60-90 days, respectively. Five (4.7%) patients remained asymptomatic and 68 (62.8%) were febrile, with a median fever duration of 2 days. The most common symptoms were respiratory including cough (66.6%), nasal stuffiness (51.4%), and rhinorrhea (40.9%). Blood cultures were performed in 10 infants but no organisms were detected. Cultures of bag-collected urine specimens from 8 infants were grown, resulting in positive growth for 2 without pyuria. Nine (8.6%) infants were treated with empirical antibiotics for a median duration of 2.3 days (range, 1-7 days). All 105 infants showed improvement without any complications, and there were no fatal cases. Conclusions: In this study, most infants aged ≤90 days with COVID-19 presented with mild symptoms and none of those evaluated had documented bacterial co-infection. The favorable prognosis among young infants with SARS-CoV-2 may aid clinicians in tailoring their approach to evaluation and management during outbreaks.

Recent research indicates that the n-3 fatty acid , docosahexaenoic acid(22 : 6n 3, DHA) plays an essential role in infant brain development . DHA is highly concentrated in brain and retinal tissues and accumulates during late fetal and early neonatal life. Diets deficient in DHA are associated with reduced levels of DHA in brain and retinal tissues. The purpose of this study is to investigate the long term effects of DHA supplementation on the growth and mental development of full-term infants. THirty four healty infants were recruited from those who were delivered at Kyung Hee Medical Center. The experimental groups were the breast milk+DHA(-) group who were fed human milk for 20 weeks after birth and thereafter were fed placebo formula for 28 weeks, the breast milk+DHA(+) group who were fed human milk for 20 weeks after birth and thereafter were fed DHA supplemented formula for 28 weeks, DHA(-) group who were fed placebo formula for 48 weeks, and DHA(+) group who were fed DHA supplemented formula for 48 weeks. The daily average intake of DHA for the breast milk+DHA(-) , breast milk+DHA(+), DHA(-) and DHA(+) groups were 39.1mg, 89.9mg, 17.7mg, and 160.224mg, respectively. The results showed that measurements of infant weight, length, head, and chest circumferncewere all in normal range and they were not influenced by the DHA supplements in their diets. There was a significant correlation between dietary DHA intake and erythrocyte DHA level. The results of flash visual evoke potential (VEP) test were not correlated with eerythrocyte DHA and dietary DHA levels at 48 weeks of age. No differences were found in Bayley mental and Psychomotor Development lndex scores among the four experimental groups at 48 weeks of age. Unlike the short-term effects there was no long-term effect of relatively small amounts of dietary DHA supplements on the scores for flash VEP and Bayley test, even thour호 there was an elevated DHA supplements on the scores for flash VEP and Bayley test, even through there was an elevated DHA content in the infants erythrocytes.

일반적으로 영유아기 라고 하면 출생 후 학령기 이전까지의 시기를 말하나 여기서는 출생 후 약 2년까지의 시기에 대하여 집중적으로 거론하고자 한다. 이 시기의 아기들, 특히 만 1세 이전의 영아들은 신체적, 정서적으로 일생을 통해 가장 변화의 폭이 큰 성장 곡선을 그리면서 성장한다. 이러한 급격한 성장은 단지 키나 체중 등에만 국한되는 것이 아니라 신체내 모든 조직의 구성이나 기능 둥에도 해당되며, 소화 생리를 포함한 생리적, 면역학적 기능과 기계적 운동 기능 등이 다양하게 포함된다. (중략)

섬유공업에서 섬유원료단계의 세정을 출발로 실 및 직물제조 단계를 거쳐 제조된 직물의 가호, 탈호, 정련ㆍ표백, 염색ㆍ가공 공정 등의 모든 공정에 수세공정이 포함되어 있다. 이러한 공정에는 많은 양의 물이 사용될 뿐만 아니라 환경 오염의 원인이 되는 약제들 또한 다량 사용되므로, 섬유공업의 발전 초기단계부터 부수적으로 발생되는 환경 폐수를 줄이거나, 오염 물질의 발생을 유발하지 않는 방법에 대하여 활발한 연구가 이루어져 왔으나 현재까지도 크게 실효를 거두지 못하고 있다. (중략)

The purpose of this study was to examine the effects of variables of interest on mothers' choices of infant care. The variables of interest in this study were categorized into the following three areas: 1) demographic characteristics of mothers and infants, 2) structural and procedual dimensions of infant care facilities, and 3) maternal beliefs on child-rearing. The subjects of this study were mothers whose infants were currently cared by at infant care facilities(n=185) and those who were on the waiting list to use non-maternal infant care(n=53). The main results of this study were as follows. First, mothers of this study preferred to select a type of center-based subsidized infant care over other types of care(family day care) due to quality of the program. Second, the mothers who were not using infant care and cared for their infants at homes reported that there were limitations in their choices of types of infant care due to accessibility and availability of public subsidized infant care facilities, and their child rearing goals were more likely to emphasize learning achievement and maturity than character education or personality. The mothers were more likely to choose a family home care over center-based public subsidized care when they were employed, had younger infants, had longer period of time on waiting lists, and emphasized structural dimensions of infant care than center-based care users. Implications for research and practices were discussed along with the main results of this study.

This study analyzed the research trends related to parenting stress of parents with infancy. To this end, 82 papers in journals registered in the KCI from 1998 to 2019 were reviewed. The frequency and percentage were calculated and analyzed for each research period, research topic, research type, and research subject. The research results were as follows. First, from 1998 to 2019, there was a continuous increase in each period. Second, regarding the research subject, the themes related to parents were the most researched, followed by the child, parenting environment, and parent-child. Among the topics related to parents, research on the variables related to parenting beliefs and behaviors was the highest. Third, quantitative research was absolute, and no qualitative research was conducted. Among the quantitative studies, the most common test method was through a questionnaire. Fourth, regarding each research subject, the research of mothers was dominant, followed by mother-infant, parent, and parent-infant-teacher. This study is significant because it provides an opportunity to broaden the scope of research and academic interest in the parenting stress of infancy parents.

The purpose of this study was to compare maternal attitude and self confidence for infant care of primiparas of rooming-in and not rooming-in. The subjects were 128 primiparas who had delivered at eight general hospital in Seoul. 67 primiparas were in three rooming-in facilities and 61 primiparas were in five not rooming-in facilities. The data were collected from primiparas using Cohler's Maternal Attitude Scale and Pharis' Self Confidence Scale at postpartal 1 or 2 weeks. The results of this study were as follows : 1. The mean of maternal attitude was 100.32 and the range was from 82 to 138. The score of primiparas in rooming-in(100.94) was higher than those of not rooming-in(97.43). There was a significant difference in maternal attitudes between rooming-in group and not rooming-in group(P=.001). There were no significant differences in maternal attitude according to age and infant sex. But types of feeding were related to maternal attitude (P=.017). 2. The mean of self confidence for infant care was 119.55 and the range was from 58 to 173. The mean of primiparas in rooming- in(123.10) was higher than those of not rooming-in (115.86). There was a significant difference in self confidence for infant care between rooming-in group and not rooming- in group (P=.040). No significant differences existed in self confidence for infant care according to age, infant sex, and types of feeding. 3. The rate of breast feeding was 64.2% in rooming-in group and 34.4% in not rooming-in group at postpartal 1 or 2 weeks. There was a significant difference in breast feeding between the two groups(P=.004). In conclusion, rooming-in facilities provided primiparas with more positive maternal attitude and greater self confidence for infant care and increased the rate of breast feeding.

Purpose : Enterovirus is a common cause of aseptic meningitis and nonspecific febrile illness in young children. During the summer and fall months, enterovirus-infected young children are frequently admitted and evaluated to rule out bacterial sepsis and/or meningitis. The purpose of this study was to evaluate the relationship between nonpolio enterovirus infection and febrile illness in infants under 3 months of age during the summer, fall months by using a stool culture to identify the presence of enterovirus. Methods : Patients included febrile infants under 3 months of age admitted to Masan Fatima Hospital for sepsis evaluation from May 1999 to September 1999. Cultures were performed from stool and Cerebrospinal fluid samples and then were tested for enterovirus infection. Viral isolation and serotype identification were performed by cell culture and immunofluorescent testing. Enteroviruses not typed by immunofluorescent testing were confirmed by reverse transcription-polymerase chain reaction. Results : A total of 44 febrile infants were enrolled; of those, 20(45%) were positive for enterovirus. Two enterovirus culture-positive infants had concomitant urinary tract infection and one had Kawasaki disease. All infants infected with an enterovirus recovered without complications. Serotype of 20 enteroviruses were isolated from stool, 3 of echovirus type 9, 1 of echovirus type 11, 1 Coxsachievirus type B4, 15 of untyped enteroviruses. One untyped enterovirus was isolated in the CSF. Conclusion : Nonpolio enterovirus infections are associated with nonspecific febrile illnesses in infants under 3 months of age.
