조기 영어교육이 필요한 것인지, 그리고 효과가 있는 것인지에 대해서는 2000년대 이후 많은 연구들이 실시되어 왔으나, 상당수 연구들은 통제집단의 부재, 관련변인 통제의 실패, 혹은 간이검사의 사용 등으로 인해 해석의 어려움이 존재했다. 본 연구는 8개월간의 영어학습 프로그램이 유아의 영어능력에 유의미한 효과를 미치는 지를 알아보기 위해 미국에서 공식 언어검사로 가장 많이 사용되고 있는 WIDA검사를 사용하여 개입집단과 통제집단의 영어능력치를 3회에 걸쳐 측정하였다. 또 영어학습이 본격화 되기 이전의 아동의 한국어 능력, 지능, 성격변인, 그리고 부모의 사회경제적 변인 및 영어교육에 대한 태도를 측정하고 이를 통제하여 영어학습만의 고유효과를 알아보고자 하였다. 3차 검사를 완료한 39명의 유아들의 영어능력을 분석한 결과, 개입집단은 수용언어 발달과 표현언어 발달에 있어 관련변인의 효과를 통제한 후에도 여전히 통제집단 유아에 비해 우수하였다. 하지만 이러한 효과는 영어검사의 정답문항 수에 근거하였을 때에만 유의미하였으며, 집단간 질적인 측면에서 유의미한 변화는 발견되지 않았다. 본 연구의 결과는 단순 노출교육이라 하더라도 조기영어교육은 최소한 단기간 효과가 있음을 시사한다.

Objectives : The purpose of this study was to examine the prenatal, perinatal and developmental risk factors of attention-deficit hyperactivity disorder (ADHD), compared to unaffected siblings (SIB), and typically developing children (TC). Methods : Subjects with ADHD, their SIB, and TC were recruited from the child psychiatry outpatient clinic of the Asan Medical Center Children's Hospital. The parents of the children completed questionnaires on perinatal and developmental risk factors. Results : Fifty-eight subjects with ADHD (41 boys, $7.7{\pm}1.3years$), 21 SIB (8 boys, $8.2{\pm}1.8years$), and 22 TC (8 boys, $8.5{\pm}2.1years$) were included. The ADHD group showed higher rates of maternal stress during pregnancy than the SIB group (p=.002), and the ADHD group showed higher rates of familial psychiatric history than the TC (odds ratio, 8.76 ; 95% confidence interval, 1.69 to 45.45). Conclusion : These findings suggest that among perinatal and developmental factors, maternal stress during pregnancy contribute to the development of ADHD. Future prospective studies will be needed in order to determine the causal relationship between perinatal risk factors and development of ADHD.

Purpose: Common conditions, such as dehydration or respiratory infection can aggravate hypoxia and are associated with interstage mortality in infants who have undergone palliative surgery for congenital heart diseases. This study was done to evaluate the efficacy of a home monitoring program (HMP) in decreasing infant mortality. Methods: Since its inception in May 2010, all infants who have undergone palliative surgery have been enrolled in HMP. This study was a prospective observational study and infant outcomes during HMP were compared with those of previous comparison groups. Parents were trained to measure oxygen saturation, body weight and feeding volume and to contact the hospital through the hotline for emergency situations. Telephone counseling was conducted by clinical nurse specialists every week post discharge. Results: Forty-one infants were enrolled in HMP. Nine hundred telephone counseling sessions were conducted. Seventy-three infants required telephone triage with the most common conditions being gastrointestinal (50.7%) and respiratory symptoms (32.9%). With HMP intervention, interstage mortality decreased from 18.6% (8/43) to 9.8% (4/41) (${\chi}^2$=1.15, p=.283). Conclusion: Results indicate that active measures and treatments using the HMP decrease mortality rates, however further investigation is required to identify various factors that contribute to hemodynamic complications during the interstage period.

Objectives:The objective of this study was to examine the perinatal and developmental risk factors of attention-deficit hyperactivity disorder (ADHD) diagnosed with a structured interview among Korean children. Methods:The current study included 924 children (6-15 years) recruited from schools in five Korean cities or a child psychiatry outpatient clinic of Seoul National University Children's Hospital. The parents of the children completed the structured diagnostic interview for attention-deficit hyperactivity disorder, as well as questionnaires on perinatal and developmental risk factors. Results:Preterm delivery, severe maternal stress during pregnancy, change in primary care taker during the first three years, postpartum depression, and delayed first sentence showed a significant association with ADHD diagnosis. Conclusion:These findings suggest that perinatal and developmental factors contribute to development of ADHD in Korean children. Conduct of future research using a prospective design is needed in order to identify the causal relationship between observed risk factors and development of ADHD.

Background & Objectives: In patients with gastric cancer, the most frequently reported family history of cancer also involves the stomach. The aim of this study was to assess the presence of gastric precancerous lesions in first-degree relatives of patients with gastric cancer and to compare the obtained results with those of individuals with no such family history. Methods: Between 2007 and 2009, 503 consecutive persons more than 30 years old were enrolled in the study covering siblings, parents or children of patients with confirmed adenocarcinoma of stomach. The control group was made up of 592 patients who were synchronously undergoing upper gastrointestinal endoscopy for evaluation of dyspepsia without gastric cancer or any family history. All subjects were endoscopically examined. Results: The overall prevalence of Helicobacter pylori was 77.7% in the cancer relatives and in 75.7% in the control group. Chronic gastritis was found in 90.4% vs. 81.1% (P<0.001). Regarding histological findings, 37(7.4%) of the study group had atrophy vs. 12(1.7%) in the control group (P<0.001), while no difference was observed for intestinal metaplasia (20.3%vs. 21.6%, P=0.58). Dysplasia were shown in 4% of cancer relatives but only 0.4% of the control group (P<0.001). There was no gender specificity. Conclusions: Findings of our study point to great importance of screening in relatives of gastric cancer patients in Iran.

The convergence progress in science technology and ensuing changes in educational environments require another huge change in education programs in the 21st century defined as a knowledge-based information society. But nowadays, prospective college students are increasingly avoiding natural science and engineering. So, educational fields in korea need suitable convergence educational programs (STEAM: science, technology, engineering, arts, mathematics) for creative competent person who is training and experiencing. In addition, environmental design fields are predicting about spread of Kinetic architecture. Therefore the aim of this study is developing convergence hand-on educational program which is incorporate robot science into environmental design for children. The program and teaching materials were developed by mapping between robot science and environmental design process leading the Design Promote Committee in KIID(Korea Institute of Interior Design) supported research teams in Hansung University. And then, For utility of the program, we had a 3 times of demonstration of empirical education. First, graduate students of design and robot major, and small group of children who are selected, at last, 63 children who are applying the program randomly. For more high quality program, we were conducting survey of post-empirical education evaluation for children and their parents. In conclusion, we found out highly satisfaction of the program those two groups. Also they need more organized places, time, task and so on. And the convergence educational program would develop by systematic approach and empirical research. At last, various and series convergence programs and teaching materials would develop creative competency based for regular and irregular courses of whole educational period.

Background This study has been conducted with the aim of evaluating modified T-plate interpositional arthroplasty. Methods A prospective comparative study in patients admitted with temporomandibular joint ankylosis. Ankylotic temporomandibular joint arthroplasty included condylectomy gap arthroplasty in 7, temporalis muscle flap interpositional arthroplasty in 8, and modified T-plate interpositional arthroplasty in 13 cases. The patients were followed for three years. Collected data were tabulated and subjected to Fisher's exact test, chi-square test and probability estimation. Results A significant increase in interincisal distance of 32 mm was seen in 12 (92.31%) patients in the T-plate interposition group, in 2 (25%) cases of the temporalis muscle flap interposition group, and in 1 case (14.28%) of the condylectomy group at 12, 24, and 36 months. Re-ankylosis was observed in 1 case (9.69%) of the T-plate interposition group, while as it was observed in 4 (50%) cases in the temporalis muscle flap interposition group and 4 (57.14%) cases in the condylectomy group, and these differences were statistically significant. Conclusions Our clinical experience with the use of the T-plate over the past 5 years has been encouraging, and our physiotherapy technique is quite simple. Even illiterate parents can assess it easily. Hence, we recommend this easy technique that does not damage the temporalis muscle for the management of temporomandibular joint ankylosis.

Purpose: Thickened infant formulas reduce regurgitation frequency and volume. Because the digestive tolerance of locust bean gum-containing formulas is controversial, the effectiveness and tolerance of a locust bean gum-thickened formula in infants presenting with regurgitation was evaluated. No other interventions were allowed during the 1 month follow-up period. Methods: We conducted an open, prospective, observational study of a locust bean gum-thickened formula administered to infants presenting with moderate to severe regurgitation according to parents during 1 month. Effectiveness and tolerance were assessed by evaluating gastrointestinal symptoms and quality of life indicators. Results: A total of 2,604 infants with an average age of 9.3±4.3 weeks were included in this 1 month trial. Regurgitation frequency and estimated volume decreased significantly (p<0.001) and the episodes were resolved completely in 48% of the infants. A significant decrease in duration of crying and episodes of gas (p<0.001), with improvement in quality of life parameters, was observed. Stool frequency increased and stool consistency softened (p<0.001) to levels within the physiologic range, consistent with the increased fiber load (0.42 g/100 mL). Conclusion: Locust bean gum-thickened formula decreased infant regurgitation, was well tolerated, and improved parental quality of life. Stool composition and frequency of the infants remained within the physiologic range.

Purpose: This study investigated correlations between the actual sleep time 24 hours prior to an examination and the time to achieve chloral hydrate sedation in pediatric patients. Methods: With parental consent, 84 children who were placed under moderate or deep sedation with chloral hydrate for examinations from November 19, 2020 to July 9, 2022 were recruited. Results: Patients' average age was 19.9 months. Pediatric neurology patients and those who underwent electroencephalography took significantly longer to achieve sedation with chloral hydrate. There was a negative correlation between the time to achieve sedation and actual sleep time within 24 hours prior to the examination. Positive correlations were found between the actual sleep time 24 hours prior to the examination and the second dose per weight, as well as between the sedation recovery time and awake hours before the examination. Conclusion: Sleep restriction is not an effective adjuvant therapy for chloral hydrate sedation in children, and sedation effects vary according to pediatric patients' characteristics. Therefore, it would be possible to reduce the unnecessary efforts of caregivers who restrict children's sleep for examinations. It is more important to educate parents about safe sedation than about sleep restriction.

BACKGROUND/OBJECTIVES: Inadequate nutrition in infants and young children affects physical growth and neurocognitive development. Therefore, early nutritional intervention is important to promote catch-up growth in young children with faltering growth. The aim of this study was to evaluate the effect of nutritional supplementation with a pediatric concentrated and balanced nutritional supplement formula on promoting growth and improving nutritional status in children with nonorganic faltering growth. SUBJECTS/METHODS: Children aged 12-36 months whose body weight-for-age was < 5^th percentile on the Korean Growth Charts were enrolled. Children born premature or having organic diseases were excluded. Children were instructed to consume 400 mL of formula per day in addition to their regular diet for 6 months. Pediatricians and dietitians educated the parents and examined the subjects every 2 months. Anthropometric parameters were measured at baseline and at 2, 4, and 6 months, and laboratory tests were done at baseline and 6 months. The good consumption group included children who consumed ≥ 60% of the recommended dose of formula. RESULTS: Total 82 children completed the 6-month intervention. At baseline, there were no significant differences in all variables between the good consumption and poor consumption groups. Weight and weight z-scores were significantly improved in the good consumption group compared to the poor consumption group at the end of the intervention (P = 0.009, respectively). The good consumption group showed a significant trend for gaining weight (P < 0.05) and weight z-score (P < 0.05) compared to the poor consumption group during 6 months of formula intake. The concentration of blood urea nitrogen was significantly increased in the good consumption group (P = 0.001). CONCLUSIONS: Nutritional supplementation with a concentrated and balanced pediatric nutritional formula along with dietary education might be an effective approach to promote catch-up growth in children with nonorganic faltering growth.
