The purpose of this study is to compare the meaning of the experience of robot play in the free play time of 5-year-old children in daycare centers with the experience of 5-year-old children in the structural group activities of teachers. To this end, a total of 32 children (15 in the experimental group and 17 in the comparative group) aged 5 were conducted for 1 hour three times a week for 10 weeks. Robots were supported as toys in the classroom of the experimental group, and children in the comparative group freely experienced robot exploration and play during free play time, and children in the comparative group learned the robot's functions and performed structural group activities based on the 2019 Revised Nuri Curriculum national-level curriculum. As a result of analyzing the difference between pre-test and post-test, the use of robots in free play showed a significant effect in creativity and fluency of children, and a significant effect in expression of pleasure in playability. These results suggest that robots are meaningful as play materials in early childhood education, which aims for infant-led free play, and that it is worth studying the robot experiences of children in these free situations in the future.

Purpose: The incidence of hepatitis A virus(HAV) infection has markedly decreased in the last 20 years due to industrialization and improvements in the standard of living and hygiene in Korea. The reduction in seroprevalence rates indicates infection potential for young adult population, and a need for vaccinations in high-risk adults and children groups has been suggested. In this study we evaluated the seroprevalence rates and natural infection rates of hepatitis A in children and adolescent to obtain the basic data for vaccination of hepatitis A. Methods: A total of 334 children and adolescent subjects below 20 years old in Kyonggi-do province were examined for HAV antibody and seroprevalence rates in each age group was investigated. In 584 elementary school students residing in Kyonggi-do province, serum samples collected in 1993 and 1996 from the same subjects for investigation of natural seroconversion rates. Method of testing antibody was enzyme immunoassay. Results: 1) The seropositive rate of HAV in 334 subjects aged below 20 years old was 5.4%. According to age, the seropositive rates were 27.3% in infant group, 0.0% in 1~4 year-old group, 0.0% in 5~9 year-old group, 2.9% in 10~14 year-old group and 15.0% in 15~19 year-old group. 2) In the study of 584 elementary school children, only one subject showed seropositive in 1993, and in 1996 three different subjects showed seropositive results(0.5%); the natural seroconversion rate during 3 years was 0.5%. 3) The seroprevalence rates of below 20 year-old subjects reported in previous studies were 63.8% in 1979 and 47.3% in 1989 while the present study showed the rate at 5.4%. Conclusion: Since natural antibody formation is rarely occurring, there is a high risk for apparent hepatitis A infection in adults. Therefore vaccination in high risk groups is essential at present, and in order to reduce the chance for hepatitis A infection in adults, vaccination in children may be needed.

Purpose: Safety pin ingestion is common in some regions of the world and may lead to severe morbidity and mortality. The aim of this study was to present some practical suggestions for ingested safety pins using an accompanying algorithm, presented for the first time in the literature to the best of our knowledge. Methods: Twenty children with ingested safety pins during a 4-year period were retrospectively included in the study. Results: Median age of patients was 9.5 months (interquartile range, 6.3-14 months), and 70% were girls. On endoscopic examination, safety pins were observed in the stomach (25%), duodenal bulb (20%), upper esophagus (15%), middle esophagus (10%), and second part of the duodenum (10%) but were not observed in 20% of the cases. Safety pins were removed using endoscopy in 15 cases (75%). In four cases (20%), no safety pin was observed on endoscopic examination. In one case (5%) involving a 6-month-old infant, the safety pin could not be removed although it was observed using endoscopy. No surgical intervention was needed for any patient. No complications such as perforation or deaths developed, except for erosions, due to the foreign body removal procedure. Conclusion: Safety pins are easily removed endoscopically. The best option is to remove the safety pin using endoscopy while it is still in the esophagus and stomach. For this reason, endoscopic procedures should be performed as soon as possible in children who have ingested safety pins.

Despite the 12-year KNA breastfeeding campaign, the declining trend in the national breastfeeding rate has not been significantly reversed. Purpose: This investigation focused on mothers' decision to breastfeed and the physical growth profiles of breastfed infants. Methods: Participants were 146 mothers and their 5-7 months old infants participating the "Year 2005 Healthy Breastfed Baby Contest." Data were collected through interviews with mothers on their breastfeeding practice and assessment of infant growth profiles by the investigators. Results: Concerning breastfeeding practice, 76% of mothers decided to breastfeed even before their pregnancy and 92% intended to breastfeed a year or as long as baby wants and 52% planned to breastfeed solely by self-motivation from reading. The growth profiles of breastfed infants showed that for WAZ (weight-for-age Z-scores), LAZ (length-for-age Z-scores) and HCAZ (head circumference-for-age Z-scores) the breastfed infants were above the WHO percentiles for their age. Conclusion: Considering that the mothers planned to breastfeed even before pregnancy and that the physical growth of the breastfed infants was above WHO standards, the authors recommend that in future campaigns the focus should be on families who plan to have a baby.

Objectives: This study examined whether the infant feeding type and duration are related to the introduction of complementary feeding, and whether the appropriate introduction of complementary feeding in infancy is related to tooth decay in toddlers. Methods: The subjects were 1,521 toddlers among 2~3 year old children in the Korea National Health and Nutrition Examination Survey from 2008 to 2015. The toddlers were divided into the appropriate group (4~6 months) and delayed group (>6 months) according to the timing of complementary feeding introduction. Results: The delayed group were 26.5% of subjects and the formula feeding period in the appropriate group and delayed group was 8.4 and 10.3 months, respectively (P=0.002). On the other hand, there was no difference in the breastfeeding period between the appropriate group and delayed group (P=0.6955). Early childhood caries was more common in the delayed group (P=0.0065). The delayed introduction of complementary feeding was associated with a risk of early childhood caries according to the logistic models (OR 1.81, 95% CI 1.27-2.57). Conclusions: The introduction of complementary feeding is associated with early childhood caries. Therefore, the importance of the proper introduction of complementary feeding in infancy should be emphasized, and public relations and education for maternal care and breastfeeding should be provided through health care institutions.

This is a report of a chylous cyst in the mediastinum found in a 61 year old Korean female patient who suffered from mild swallowing difficulty and right chest discomfort. These symptoms had developed 5 years previously when chest P-A view showed thumb-tip sized mass shadow in right mediastinum, just right to ascending aorta. Esophagogram revealed an indentation of midesophagus. Follow up checks showed growing mass shadow which suggested aneurysm of ascending aorta. On admission chest X-ray revealed a well circumscribed infant head sized mass density along the right heart border and middle mediastinal border, and extended near to the middle clavicular line in right chest cavity. Aortogram revealed no relationship between the mass and aorta. Right thoracotomy was performed under impression of mediastinal tumor. There was a large cyst containing 700 cc of milky fluid. There was no connection to the thoracic duct nor adjacent organs. The fluid was analyzed chemically and identified the fluid as chyle. The origin of the isolated chylous cyst was uncertain postoperative course was uneventful.

Through the questionaire inquiry from April 1st to 10th, 1974 with 393 students in Woonho, Saekwang junior and senior highschool and Daisung, Ilshin girls' junior and senior highschool in Chungju, Choong Cheong Buk Do, I surveyed the general circumstances of students and their unbalanced diet on total 199 foods and causes of the unbalanced diet and regard the 21 boys and 29 girls who don't like to eat more than 30 foods from the given 47 protein-foods which are needed by students who are now in the stage of growth. This study is concerned with their circumstances and the causes of their ill habit of eating. 1) As to their distribution of age, 14 and 18 year old boys were six (28.5%), 11 and 13 year old girls were eleven (38.1%). In the survey on their height, 6 boys (28.5) were from 146 cm to 150 cm and 11 girls (38.1%) were from 146 cm to 150 cm. On the weight, 7 boys were from 36 kg to 40 kg(33.7%), 10 girls were from 36 kg to 40 kg (34.0%). We can see that ill habiters of eating were more weaker than other students from this data. 2) In the survey of educational level of their housewive it was found that number of graduates of the primary school is thirty (60.0%). So we can derive the fact that they don't make any variety in their daily table for their family. 3) As to their living standard, 19 boys (90.4%) and 27 girls (93.3%) belong to the middle class, low and high class were a little. This indicates the general living standard if Korea, because in common sence we regard the riches are the more ill habiters of eating. 4) 8 boys (36.8%) and 8 girls (26.8%) were the first children in their homes. This indicates the fact that housewive happen to make the first child as the ill habiter of eating because their lack of experience to give various food for their children. As to the survey on their infant nutriments, 41 students (80.2%) were fed by mother's milk. 5) Upon the causes of the unbalanced diet on a certain food, 34 boys (82.7%) and 45 girls (64.6%) were because of appearing to that food, 10 boys (40.8%) and 18 girls (61.5%) were because of the characteristic fragrance, 11 boys (52.4%) and 17 girls (58.1%) were because they have never eated that food till now, 34 boys (19.3%) and 5 girls (17.0%) were because of the bad appearance of the food. So housewive should study various ways of cooking daily meals at home and try to give their children who are in the stage of growth to be able to eat wider kinds of foods for the improvement of health.

Munro is generally considered the first person to have demonstrated, in 1888, in an infant cadaver, the feasibility of dissection and ligation of a persistently patent ductus arteriosus. In august, 1938, Robert Gross reported first successful division and suture of the patent ductus of 7 year old girl. Interruption of a ductus is one of the most satisfactory and curative operations in the field of surgery for congenital heart disease. Seventy-eight consecutive cases of closure of patent ductus arteriosus were operated from June 1980 to June 1988 in the department of thoracic and cardiovascular surgery in Maryknoll Hospital. Retrospective clinical analysis of the patients were 1. There were 24 males, 54 females. 2. The age range of the patients were from 7 months to 32 years with the mean age 9.8 years. 3. Chief complaints of the patients were frequent URI[70.5%], dyspnea on exertion[36.9%], palpitation[10.3%], but 15 patients[19.2%] had no subjective symptoms. 4. Continuous machinery murmur could be heard at the 2nd or 3rd intercostal space on the left sternal border in 66 patients[84.6%]. The other 12 patients made systolic murmur. 5. Radiographic findings of the Chest P-A were cardiac enlargement in 55 patients[70%], enlargement of pulmonary conus and/or increasing density of pulmonary vascularity in 68 patients[87%]. 6. Electrocardiographic findings of the patients were within normal limit in 23 patients[36%], LVH in 38 patients[48.7%], RVH in 7 patients[9%], biventricular hypertrophy in 5 patients[6%]. 7. Cardiac catheterization performed in 62 patients. Mean Qp/Qs=2.5, mean pulmonary arterial pressure=45 mmHg. 8. 73 patients were operated through left posterolateral thoracotomy: Closure of the ductus by ligation in 64 cases, division with suture in 6 cases, and division with aortopatch in 3 cases. Ligation through median sternotomy under cardiopulmonary bypass were 5 cases. 9. There was no death associated with operation, but one case was experienced with intraoperative tearing of ductus resulting in massive bleeding. The other complications were transient hoarseness in 2 patients, chylothorax in 2 patients.
