Purpose : Iron deficiency anemia (IDA) is one of the most common nutritional deficiencies in children on a weaning diet. We investigated weaning practices in infants and children, as well as their mothers' knowledge about weaning. Methods : We investigated 129 children with IDA and 166 without IDA (aged 6-36 months) who had visited 10 university hospitals between March 2006 and July 2007. We investigated the hematologic values of both groups. A questionnaire on weaning was answered by the mothers of these children. Results : The hematologic values in the IDA group showed a significant difference from those in the comparison group (P<0.05). Children who were solely breastfed until 6 months of age were 85%, 34% (P<0.05), and weaning was started by 6.3, 6.4 months, respectively (P>0.05). Rice gruel, boiled rice, and fruit juice accounted for approximately 80% of the starting foods in both groups (P>0.05). Only 40% of the children in the IDA group had a balanced diet within a month, versus 38% in the comparison group. In response to questions about the necessity of iron-fortified foods for breast-fed infants, less than 50% of mothers in both groups answered correctly. In the IDA group, 42% showed serum ferritin less than 10 ng/mL, while 92% showed serum MCV less than 72 fL. Conclusion : In conclusion, collection of information on history should be thorough for feeding and selective examinations for IDA in high-risk groups. Considering the adaptation period, we suggest beginning children on a weaning diet at 45 months. In addition, we need to educate mothers on weaning practice, especially on the necessity of iron-fortified foods for breast-fed infants.

Purpose : Twins have a higher mortality and morbidity than singletons. Co-twin with one fetal death is particularly at risk. We investigated the neonatal outcome of live co-twins when one fetus had died after the 20th gestational week, and associated risk factors. Methods : A retrospective study was performed in fifteen cases of twin pregnancy with single intrauterine fetal deaths after the 20th gestational week during the period from January 1996 to December 2000 at Chonnam University Hospital. Results : Gestational age was $33.7{\pm}3.2weeks$, birth weight was $1,992{\pm}592g$. Interval between one fetal death being detected and the delivery of a live co-twin was $32.4{\pm}29.5days$. There were 11 cases(73.3%) of premature babies less than 37 gestational weeks. Main causes of preterm delivery were preterm labor and premature rupture of membranes. Hematologic findings suggesting disseminated intravascular coagulopathy(DIC) were not found in all mothers before delivery, and was not associated with DIC and encephalomalacia of the live co-twin. Perinatal outcome of fifteen live co-twins was as follows : six were normal(40%), three were DIC(20.0%), three were encephalomalacia(20.0%), one suffered intrauterine growth retardation, there was one case of twin to twin transfusion syndrome, and one of congenital heart disease(atrial septal defect with pulmonary stenosis). The occurrence of DIC and encephalomalacia in live co-twins was not related to placental chorionicity, birth weight, gestational week, and the interval between the detection one fetal death and the delivery of a live co-twin. Conclusion : We could not find any maternal hematologic problems in twin pregnancies complicated by one fetal death. Twenty percent of live co-twins showed DIC and encephalomalacia. However, its associated risk factors were not found. We need to investigate more closely the cases of live co-twins with one intrauterine fetal death.

Purpose : Early identification of developmental disabilities allows intervention at the earliest possible point to improve the developmental potential. The Ages and Stages Questionnaire (ASQ), a parent- completed questionnaire, can be used as a substitute for formal screening tests. The purpose of this study was to evaluate the validity of the Korean version of the ASQ (K-ASQ) as a screening tool for detecting developmental delay of young Korean children in the setting of a busy pediatric outpatient clinic. Methods : Parents completed the K-ASQ in the waiting room of the pediatric outpatient clinic of St. Mary's Hospital, Catholic University Medical College. Out of 150 completed the ASQ, 67 who were born term and had no previous diagnosis of developmental delay, congenital anomalies, or neurological abnormalities were enrolled. The cut-off values of less than 2 standard deviations (SD) below the mean for the ASQ were used to define a "fail", and children who failed in one or more domains tested were classified as "screen-positive". Diagnosis of developmental delay was made when the developmental indices fell below -1 SD of the Bayley Scales of Infant Development-II. Results : (1) The mean age of children was $16.4{\pm}7.4$ months. Ten children (14.9%) were small-for- gestational age infants. The mean birth weight and gestational age were $3.1{\pm}0.6kg$ and $38.8{\pm}1.4$ weeks. Nine children (13.4%) were twins and 33 (49.0%) were male. The mean maternal education in years was $13.6{\pm}2.4$, and 31.3% had full-time jobs. The time for completing the ASQ was $10.2{\pm}3.0$ minutes. (2) Seventeen children (25.4%) were classified as screen-positive, four of them were delayed in development. Among eight children diagnosed with developmental delay, four were screen-positive and the other four were screen-negative by the ASQ. (3) The test characteristics of the ASQ were as follows: sensitivity (50.0%); specificity (78.0%); positive predictive value (23.5%); negative predictive value (92.0%). Conclusion : The high negative predictive value of the K-ASQ supports its use as a screening tool for developmental delay in the setting of a pediatric outpatient clinic.

Purpose : The purpose of the present study was to access the prevalence of orthostatic dysregulation(OD) and the frequency of each category for major and minor criteria among elementary school students using the OD questionnaire. Methods : We carried out inquiry by questionnaire as to the frequency of OD among two elementary schools with 725 students, 10 to 12 years of age, residing in Gwangju, Korea. The questionnaire was made according to criteria proposed by the Japan OD Study Group. Results : Of the 725 students(male 390; female 335) questioned, the OD was found in 338 students (53.5 percent). Prevalence of OD in males(59.2 percent) was significantly higher than in females(46.8 percent)(P<0.05). Palpitation with slight exercise(95.9 percent) was the most frequent major symptom. Headaches(85.8 percent) were the most frequent minor symptom among cases of OD. Conclusion : The prevalence of OD in elementary school students in this study(53.5 percent) was higher than in other studies. Contrary to studies from other countries, the male to female ratio was reversed. Because the diagnostic criteria seem to be dependent on subjective reporting of the symptoms, a newer diagnostic system based on more objective findings should be established.

Purpose: The purpose of this study was to investigate the clinical manifestations and 5-year natural course of recurrent bronchiolitis or reactive airways disease (RAD) in infants. Methods: We reviewed the medical records of infants with recurrent bronchiolitis from January 2007 to December 2007 at The Catholic University of Korea St. Mary's Hospital in Incheon, South Korea. Additionally, we telephoned their parents to confirm their present medical statuses. Results: Sixty-three subjects with recurrent bronchiolitis were identified. The mean age at admission was 8.1 months and the number of males was 44 (69.8%). Of the 63 infants with recurrent bronchiolitis, inhaled corticosteroids, bronchodilators, and antibiotics were given to 62 (98.4%), 53 (84.1%), and 40 (63.5%), respectively. Among the total 63 subjects, we were able to contact the parents of 45 children by telephone. None of these children had been hospitalized during the previous one year period due to respiratory infections or for other medical reasons. Of the 45 subjects we were able to contact, 38 (84.4%) had not experienced any further respiratory difficulties at all. Five (11.1%) had been diagnosed with allergic rhinitis while two (4.4%) were being managed for asthma. Conclusion: Most children who presented with recurrent episodes of bronchiolitis in infancy did not show any further respiratory difficulties after five years of age.

The purpose of this study was to investigate the influence of the factors such as self-esteem, social supports, socio-economic status of parents, degree of disability in child, stress coping, religion, and sports.exercise on the qualities of lives in mothers with disabled children. Data were collect from 45 institutions(schools from kindergarten to senior-high, special education institutes, and social welfare institutions) by self-report questionnaire, and the subjects of the study were 386 mothers in Seoul whose children were attending the schools or institutions. Findings according to socio-demographic variables are as follows: 1. Mothers with disabled children in this study thought their quality of life as average degree. 2. The younger the mothers and children, the higher the quality of life was. 3. The higher the educational level and monthly income, the higher the quality of life was. 4. There was no statistically significant difference between the existence and nonexistence of spouse, and between the existence and nonexistence of religion as well. Findings analyzed by multiple regression are as follows: 1. Among 7 independent variables 'self-esteem'(${\beta}$=.49, p<.001), 'social supports'(${\beta}$=.15, p<.01), and 'socio-economic status'(${\beta}$=.11, p<.05) were found to be statistically significant in quality of life in mothers, while the rests were found not significant. 2. 'Self-esteem' was found to be the most influencing variable, meaning that the psychological factor such as self-esteem is more important than environmental factors in qualities of lives in mothers. 3. The total amount of explanation of the model was Adjusted R square=.301, so that it can be said about 30% can be explained among total variance of the qualities of lives in mothers with disabled children. Conclusions and recommendations based on the results above are: First, it is strongly recommended to conduct programs promoting self-esteem in mothers with disabled children, and to include 'self-esteem' hereafter in the studies related to qualities of lives in mothers with disabled children. Second, comprehensive and practical countermeasures should to be formulated to back up expenses for education and medical care, purchasing relative tools and equipments, plus helping to find jobs.

This study was carried out to identify the factors which correlated with upper limb function after stroke and to analyze the effect of related factors on upper limb function. The 100 stroke patients(MMSE-K>24) were participated. The upper limb function according to gender, hand dominance, stroke type, affected location, site of paralysis, speech disorder showed no significant difference, and show significant difference according to shoulder subluxation. The upper limb muscle strength(Manual Muscle Testing), proprioception, muscle tone(Modified Ashworth Scale), grip strength(Dynamometer), paint (Visual Analog Scale) showed significant correlations with upper limb function. These predictors explained 77.6% of the upper limb function and the most significant affecting factor of upper limb function was upper limb muscle strength. In conclusion, the upper limb muscle strengthening will be effective strategy to improving the upper limb function and considering the proprioception, muscle tone, grip strength, pain, subluxation will be helpful to develop the strategies.

잠비아의 농업지원프로그램에서 여성농가의 경우 남성농가에 비해 각종 혜택에서 소외받고 있다는 지적이 많다. 본 연구는 소규모 여성농업인이 옥수수 씨앗이나 비료 등의 농업투입요소에 대한 보조금의 혜택에서 어느 정도 차별을 받고 있는 지를 잠비아의 농업투입지원프로그램을 사례로 검증하고자 한다. 즉 농업투입요소 보조금에 대한 성차별의 영향을 주는 요인을 규명하고자 하였다. 본 연구 목적을 달성하기 위하여 관련 문헌조사가 선행되었고, 잠비아 마자부카지역의 소농가 100가구를 대상으로 설문조사를 실시하였으며 빈도분석, T-test 및 분산분석 등을 실시하였다. 그 결과 농경지의 소유 유무나 규모가 중요한 요인 중의 하나로 나타났다. 남성농가의 경우 여성농가에 비하여 자가농이 많았으며 농지 소유 규모 또한 큰 것으로 나타났다(남성농가: 평균 2.03ha, 생산량 4.43Mt, 여성농가: 평균 1.63ha, 생산량 3.15Mt). 기아의 경험 정도는 여성농가에 비해 비교적 남성농가가 높게 나타났으며, 옥수수 생산에 있어 같은 양의 투입요소라고 하더라도 여성농가가 남성농가에 비해 식량 안보력이 높은 것을 의미한다. 그러나 남성농가에 비해 여성농가의 낮은 수입이 결국 농업투입요소의 접근에 장애가 되는 중요한 요인이라 할 수 있다. 이와 같은 남성농가와 여성농가의 농업투입지원프로그램에 대한 불공평성의 문제를 해결하기 위해서는 정부 정책가들의 인식의 변화가 무엇보다도 중요하고, 여성농가를 위한 농업정보나 농작물 재배지식 등의 전달 및 훈련 등에 대하여 보다 적극적이고 체계적이며 계획적인 접근 노력이 필요할 것으로 사료된다.

Objectives: The current study investigated the personality characteristics of parents of children with attention-deficit hyperactivity disorder (ADHD) using the Minnesota Multiphasic Personality Inventory (MMPI), which is commonly used in clinical medicine. Methods: Participants were 117 parents of children with ADHD (96 boys and 21 girls) and 77 parents of comparison children (50 boys and 27 girls), who completed the Korean version of the MMPI. Results: The MMPI scores of the fathers of ADHD children were significantly higher on the Psychopathic Deviate (Pd), Masculinity-Femininity (Mf), Paranoia (Pa), and Psychasthenia (Pt) scales than the comparison group's were. In addition, the mothers of ADHD children had higher MMPI scores on the traits of Hypochondriasis (Hs), Psychopathic Deviate (Pd), and Schizophrenia (Sc) than the comparisong roup had, but were not significantly higher. Conclusion: The fathers of ADHD children might be antisocial, irresolute, passive, paranoid, and anxious. In addition, mothers of ADHD children might have hypochondriacal, antisocial, and/or psychological confusional traits, but these were not be significantly high. These results suggest that the psychopathology of parents of ADHD children might correlate with their children's ADHD.
