Objective: This study aimed to explore whether and how infants showed their empathy in everyday lives at a childcare center. Methods: The participants of this research were 10 infants (23~31 months) attending a one-year-old classroom in a childcare center located in Seoul, and the data were collected primarily thorough participant observations. Results: The infants showed four categories of empathy in their everyday lives. The first one was related to the safety of their peers; it was presented when the infants found out that their peers were sick, in trouble, and having a hard time separating from their parents, or when they found possible risks to their peers. The second one was related to the achievement of their peers; it was presented when the infants noticed their peers trying hard to continue their play. The third one was related to the infants' pleasure; it was presented when they felt shared interests and joy with their peers. The fourth one was related to the infants' self-reflection; it was presented when the infants found out that what they had been doing made their peers upset. Conclusion/Implications: These results demonstrate infants' ability to empathize with others and also imply the need to support their development of empathy continuously.

Matemal behaviors of Korean mothers of one-year-old infants (26 boys and 21 girls) were observed at home. Mothers were from middle to upper-middle class families in Seoul. Trained observers visited the infant's home for 3 to 4 hours and observed infant-mother interactions in natural situation. After the home visit, observers sorted the Maternal Behavior Q-set into 9 piles, from most characteristics to least characteristics of the mothers. In general, Korean mothers were quite sensitive and responsive in their interactions with one-year-old babies. Mothers interpreted baby's cues correctly, noticed when baby was distressed, and slowed pace down to wait for baby's response. Maternal behaviors were somewhat different according to whether they interacted with boys or girls. Mothers of boys were observed to be less sensitive in their interactions than mothers of girls. Mothers of boys were more unaware of or insensitive to baby's signs of distress, their responses were more delayed, and provided baby to constant and unphased barrage of stimulation thus made baby overwhelmed. In contrast, mothers of girls enjoyed face-to-face interactions, slowed pace down, and their interactions revolved around baby's tempo and state.

The purpose of the study was to examine the actual conditions of caregiver-infant ratios, group-room activity areas, evaluations of infant programs and caregiver-infant interactions based on structural and process indicators which are major factors of infant care. The subjects were 20 caregivers and 91 infants from 14 infant classes of 13 day care centers in Daejeon. An actual survey was conducted on caregiver-infant ratios and group-room activity areas, and teaching-learning plans for infants and daily schedules were gathered for the evaluation of infant programs. The caregiver-infant interactions were observed every one minute for a total of 20 minutes using Lee Wan Jeong's "Evaluation Measure of Caregiver-infant Interactions"(1999). The results of this study were as follows: First, caregiver-infant ratios ranged from 2.5 to 7 infants per caregiver, resulting in the difference of the number of infants. Second, the 14 classes for one-year-old infants were arranged in three different ways; 5 classrooms with distinctive activity areas, 2 without any divided areas and 7 containing a mix of partial activity areas. Third, in teaching-learning plans for infants, there were a large number of topics related to seasonal features and experiences while the fewest were about basic life habits. Fourth, in the caregiver-infant interactions, caregivers used more positive interactions and linguistic modeling than sensitive responses to infants and social interactions.

Maternal sensitivity and infant temperament were studied in relation to infant attachment security. Subjects were 47 one-year-old infants anti their mothers from intact upper-middle class families. Mothers sorted the Attachment Q-set (Waters, 1987, version 3.0) and filled out the Toddlers Temperament Questionnaire(Chu, 1992). Maternal sensitivity was observed in the home for two 3-hour sessions, and observers completed the Maternal Behavior Q-set(Pederson, Moran et al., 1990). Attachment security scores of the infants, using criterion scores developed with Korean infants, were 42, which is comparable to Previous studies. Infants who were securely attached to mothers showed more secure-based behaviors and compliance, enjoyed physical contacts, and showed less fussy/difficult behaviors with mothers. Mothers of girls were observed to be more sensitive to their infants' signals than mothers of boys. Maternal sensitivity scores were not related to infant security scores. However, maternal sensitivity was related to less compliance to mothers for boys.

The most common abnormal relationship between the great arteries and ventricle is transposition of great arteries, among which complete D-transposition is a common and lethal malformation. Without appropriate treatment, the infant born with transposition of the great arteries rarely survives the first year of life. In contrast to the grim hopelessness of only a few years ago, modern aggressive palliative and corrective surgical interventions can provide such infants with considerable hope for adolescent and adult life. Up until this time, intraatrial baffle technique for re-direction of venous return, which was proposed by Mustard originally, has been successfully applied to infants and children in many foreign clinics with decreasing trend of the operative risk. In this report, we present one case of a 4 year-old girl having complete D-transposition of the great arteries with atrial septal defect, and reviewed the relevant literatures.

Background To achieve improvements in intramuscular injection, autologous fat grafting, and gluteal artery perforator flaps in infants and children, the relationships of computed tomography (CT)-determined gluteal muscle thickness (MT) and subcutaneous tissue thickness (SCT) with age and body mass index (BMI) were analyzed. Methods Gluteal SCT and MT at ventrogluteal (VG) and dorsogluteal (DG) sites were measured in a standardized manner in 350 patients aged 0 to 6 years who had visited a tertiary hospital and had undergone abdominopelvic CT between January 2005 and December 2016. Recorded measurements were analyzed using one-way analysis of variance and stepwise multiple regression to identify the factors that were most closely related to MT and SCT. Results Subcutaneous tissue at VG sites was thinner than at DG sites, but not significantly so in any age group. Muscles tended to be thinner at VG sites in 4 to 7-year-old, but thicker at VG sites in 1 to 3-year-old, though the differences were not significant. MT in the VG and DG regions was found to be related to age, and SCT in these regions to be related to age and BMI. Conclusions The VG and DG sites should be considered as alternatives for intramuscular injection in infants and children when the anterolateral site is problematic. In addition, considering the gluteal MT and SCT of infants and children should help produce good results in autologous fat grafting and gluteal artery perforator flap harvesting.

Total anomalous pulmonary venous connection is relatively rare cyanotic congenital heart diaease, which represents 1-4% of all congenital cardiac defects. Generally in the majority cases, severe heart failure and cyanosis develops in the early infancy. Because of high mortality in the untreated infants and surgical risk, there are still many things to be improved. Two patients with total anomalous pulmonary venous connection are presented, which we recently experienced. The one was 10 year old female with supracardiac type drained through left innominate vein, and survived the operation and continuous to do well for 1 year. The other 5 year old female with mixed type (right pulmonary vein drained via coronary sinus and left pulmonary vein through left innominate vein) was operated successfully under hypothermia and extracorporeal circulation, and followed up for 6 months without problem. It was very rare case in the literature.

Precocious puberty is difficult to define because of the marked variation in the age at which puberty begins normally, onset of puberty before 8 years of age in girls and 9 years in boys may be considered precocious. The etiology of precocious puberty in boys is usually idiopathic, but can result from adrenal and testicular tumors. The hepatoblastoma that produces hCG is a very rare functioning tumor known to cause precocious puberty in boys. Recently, author experienced one case of virilizing adrenal cortical adenoma in 22 month-old boy, one case of adrenal cortical carcinoma in 28 month-old boy, and one case of virilizing hCG-producing hepatoblastoma in 7 year-old boy and reviewed literatures.

Objective: The purpose of this study was to investigate the moderate effect of the physical environmental-level between infant teachers' positive play beliefs and teacher-infant interaction. Methods: The subjects of this study were 483 teachers in charge of one-year-old and two-year-old infants in child care centers located in metropolitan areas. The data were collected by asking the teachers to respond to a questionnaire and the data collected were analyzed through correlation and hierarchical multi- regression analysis. Results: First, the positive play beliefs of the infant teacher, the physical environment level, and the teacher-infant interaction showed significant proportional correlations. Second, the physical environment level moderated the influence of the teacher's positive play beliefs on teacher-infant interaction. In particular, results showed that functional interior space configuration, outdoor playground composition and facilities among the sub-variables of the physical environment level had a moderating effect. Conclusion/Implications: The results of this study show that teachers with positive play beliefs have positive teacher-infant interaction when there is sufficient space available for infants and teachers. This indicates that the human and physical environments of child care centers can promote teacher-child interaction.

Congenital cystic adenomatoid malformation [CCAM] of the lung is a rare but often fatal congenital lung bud anomaly that causes acute respiratory distress in the newborn infants. In those who survive infancy and early childhood, its clinical manifestations are not unusual to detect. Recently we experienced two children with CCAM; one with coughing and high fever, another without any symptom On case I, the patient was a 9 year-old female, and was suffered from coughing and high fever since 15 days before. Medical treatment was failed and then, exploratory thoracotomy was performed under the impression of loculated empyema. Finally, a right lower lobectomy was done with a satisfactory postoperative course. On case II, the patient was a 12 year-old female, and admitted for evaluation of known large pulmonary cyst which was checked at the outpatient clinic. Preoperative evaluations gave no more informations, so obliteration of cysts was performed with open biopsy. Two patients with CCAM are described in Korean Univ. Medical Center.
