The author summarized the history of the physical anthropology in Korea which had bean introduced by a few Europeans in the later 19th century and then by the Japanese in the first half of the 20th oentury. The physical anthropology had two peaks in 1935 and 1967, but thereafter the published number of theses decreased by the establishment of the new degree system in Korea.

The study was conducted to measure the stature, span, body weight, standing trunk flexion and trunk extension of 989 healthy Korean school girls from age 11 to 14 and to determine the correlation coefficients among those items. The results obtained were as follows : 1. The average statures by age were 140.68cm at 11, 147.45cm at 12, 150.14cm at 13 and 154.76cm at 14 years of age, and the stature growth per year was 4.64cm. 2. The average spans by age were 137.60cm at 11, 145.52cm at 12, 149.33cm at 13 and 153.76cm at 14 years of age, and the span growth per year was 5.39cm. 3. The stature was always longer than span, but the difference between the two items decreased with the increase of age. 4. The average body weights by age were 33.89kg at 11, 38.84kg at 12,42.21kg at 13 and 47.62kg at 14 years of age, and the increase of body weight per year was 4.58kg. 5. Remarkable growth occurred in stature and spanfrom age 11 to 12, but in body weight from age 13 to 14. 6. The average standing trunk flexions by age were 5.14cm at 11, 7.50cm at 12, 11.44cm at 13, and 12.02cm at 14 years of age. 7. The average trunk extensions by age were 40.84cm at 11, 44.40cm at 12,47.68cm at 13 and 48.53cm at 14 years of age. 8. In flexibility (standing trunk flexion and trunk extension) the annual increase was the smalled from 13 to 14 years of age. This is probably because the increase in body weight becomes hindrance to flexibility 9. the correlation coefficients between stature and span showed very high values ranging from 0.93 to 0.82. The coefficients between stature and both weight as well as between body weight and span recorded high values in all age groups. But the values decreased with age. 10. the correlation coefficients between flexibilities and physical measurements showed very low values. 11. The correlation coefficients between flexion and extension were very low(0.15) at 11 and low(ranging from 0.25 to 0.37) after 12 years of age 12. The regression equations among all of the items in each age group are given in a table for reference.

We observed the histopathologic findings of 21 biopsed materials those initial clinical impression was suspected as granuloma pyogenicum. Also we compared the cange in the number of mast cells in the lesion of the granuloma pyogenicum with those in the normal appearing skin by Giemsa stain, and the stainability of mucopolysaccharides in the stromal edema of granuloma pyogenicum lesion with that in the normal appearing skin by Alcian blue-PAS stain. The results were as fallows: The various microscopic diagnoses made in 8 cases, which was clinically granuloma pyogenicurn. These 8 cases were granulation tissue(3), subungual exostosis(1), dermatofibrorna(1), sebaceous epithelioma(l), liporna with granulation tissue(1), and malignant melanoma(1). 2. The number of mast cells in the granuloma pyogenicum lesion were increased (p<0.01), especially in the lesion which showed marked capillary endothelial proliferation, and the amount of mucopolysaccharides was increased in the stromal edema of the granuloma pyogenicum lesion.

PURPOSE: After the RS (respiratory syncytial) virus, the influenza virus is the most common cause of childhood lower respiratory tract infection. We assessed the radiologic findings of childhood lower respiratory tract infection by the influenza virus. MATERIALS AND METHODS: A total of 105 pediatric patients (76 males and 29 females; mean age, 2.4 years) with symptoms of respiratory tract infection were examined between March 1997 and April 2000. Nasopharyngeal aspirates were obtained and influenza virus infection was confirmed by direct or indirect immunofluorescent assays. Peribronchial infiltration, hyperinflation, atelectasis, pulmonary consolidation, and hilar lymphadenopathy were evaluated retrospectively at simple chest radiography. RESULTS: Bilateral perihilar peribronchial infiltration was noted in 78.1% of patients (n=82), hyperinflation in 63.8% (n=67), atelectasis in 3.8% (n=4; segmental 50%, lobar 50%), and pulmonary consolidation in 16.2% [n=17; segmental 70.6% (n=12), lobar 29.4% (n=5)]. Hilar lymphadenopathy was noted in one patient in whom there was no pleural effusion, and subglottic airway narrowing in 12 of 14 in whom the croup symptom complex was present. CONCLUSION: The major radiologic findings of influenza virus infection were bilateral perihilar peribronchial infiltration and hyperinflation. In some patients, upper respiratory tract infection was combined with subgolttic airway narrowing. Atelectasis or pleural effusion was rare.

PURPOSE: Menstrual disorders are very common problems in adolescence. Most of them are minor, including mild dysmenorrhea, premenstrual syndrome(PMS) and minor variations in cycle, length, or amount of flow. Dysmenorrhea is the most prevalent among them while PMS is a nebulous condition characterized by a broad spectrum of symptoms. The purpose of this study is to investigate the correlation between dysmenorrhea and PMS in adolescents. METHODS: This cross sectional study on dysmenorrhea and PMS was performed in 1153 junior high school girls in Ansan. We researched the clinical aspects of PMS and investigated the correlation between menstrual characteristics and PMS in adolescents. RESULTS: The results are as follows : The incidence of PMS is 66.3%. The correlation of menstrual characteristics and severity of PMS was as follows : intensity of menstrual flow(P<0.01), duration of menstrual flow(P<0.05). The correlation of severity between dysmenorrhea and PMS is found(P<0.01). CONCLUSION: Korean adolescents have many problems related to dysmenorrhea and PMS. This study indicates that Korean adolescents need to be educated on the matter and treatment of their menstrual disorders are also needed.

PURPOSE: The aim of this study is to determine the clinical characteristics of early onset sepsis (EOS) in micropreemie. METHODS: We retrospectively reviewed medical records of 107 extremely preterm infants born at 25 or less than 25 weeks of gestation and admitted to the neonatal intensive care unit of Samsung Medical Center from January 2013 to August 2015. Infants were divided into two groups based on the presence of culture-proven EOS in the first 7 days of life. Retrospective analysis of perinatal factors and laboratory findings within the first week of life was done between two groups. We compared the neonatal outcomes among two groups. RESULTS: Culture-proven EOS was diagnosed in 11 of 107 infants (10.3%). Main pathogen of EOS was Staphylococcus epidermidis (45.5%). There were no significant differences between control group and EOS group in gestational age, birth weight, Apgar score, delivery type and pathologic chorioamnionitis. Among 11 infants with EOS, 9 showed fetal tachycardia (P=0.001). And EOS group presented lower platelet count at 3rd day and 7th day of life than that of control group (P=0.033, P=0.045). Neonatal outcomes in EOS group were compatible with control group. Main cause of death was sepsis in EOS group. CONCLUSION: In micropreemie, EOS is important factor of mortality. Our data suggest that fetal tachycardia and low platelet count during the first 7 days of life were associated with EOS.

Prophylactic surfactant is known to be effective to reduce chronic lung disease in preterm infants compared with rescue surfactant treatment. In Korea, early prophylactic surfactant therapy was introduced in 2011. However, recently, the increased utilization of antenatal steroids and early stabilization through continuous positive airway pressure (CPAP) in the delivery room may have changed the risks and benefits of prophylactic surfactant therapy of infants at high risk of respiratory distress syndrome (RDS). We compared the effects and safety of prophylactic surfactant therapy (within 30 minutes after birth) and early selective surfactant therapy (within 3 hours after birth) in preterm infants born at < 30 weeks gestation or with birth weight ≤ 1,250 g. The clinical data of 193 infants in period 1 (from 2008 to 2010, early selective surfactant therapy group) were collected retrospectively; those of 191 infants in period 2 (from 2012 to 2014, prophylactic surfactant therapy group) were collected prospectively. Compared to period 1, the rate of intubation and surfactant use were significantly increased in period 2. The use of multiple doses of surfactant in period 2 was significantly increased compared with period 1. Despite more invasive and aggressive management in period 2, there was no difference in the duration of mechanical ventilation, the incidence of bronchopulmonary dysplasia (BPD) or death, and the risk of other adverse neonatal outcomes between the 2 groups. In conclusion, the benefit of prophylactic surfactant therapy in infants treated under current practices is no longer clear compared to early selective surfactant therapy.

Recently it was shown that single nucleotide polymorphisms (SNPs) can explain individual variation because of the small changes of the gene expression level and that the 50% decreased expression of an allele might even lead to predisposition to cancer. In this study, we found that a decreased expression of an allele might cause predisposition to genetic disease. Dopa responsive dystonia (DRD) is a dominant disease caused by mutations in GCH1 gene. The sequence analysis of the GCH1 in a patient with typical DRD symptoms revealed two novel missense mutations instead of a single dominant mutation. Family members with either of the mutations did not have any symptoms of DRD. The expression level of a R198W mutant allele decreased to about 50%, suggesting that modestly decreased expression caused by an SNP should lead to predisposition of a genetic disease in susceptible individuals.

PURPOSE: To evaluate the safety and feasibility of delayed cord clamping compared with umbilical cord milking in premature infants less than 32 weeks of gestation. METHODS: This study was performed by 1:2 case-control match. Infants received delayed cord clamping (DCC) for one minute (DCC group, n=10, May 2014-October 2015) were compared with perinatal factors-matching controls, who received umbilical cord milking (CM, CM group, n=20, May 2014-October 2015) or who received immediate cord clamping (ICC, ICC group, n=20, January 2008-December 2008). The primary outcome was hematocrit during the first 28 days. Secondary outcomes included delivery room management, selected neonatal morbidities and mortality. RESULTS: Baseline characteristics were comparable in all the three groups. The median hematocrit level at 1st day and 3rd day was significantly higher in the DCC group (54.3±6.2%, 53.6±5.6%) as compared with the CM group (48.0±7.7%, 43.2±7.8%) or ICC group (47.2±7.5%, 45.8±6.3%). The DCC group had reductions in red blood cell transfusion within the first two weeks of life compared to the CM group (10% vs. 50%, P=0.03). The DCC group compared to the CM group had no increment in respiratory intervention in the delivery room and hypothermia on admission. There was no difference between DCC and CM in mortality, intraventricular hemorrhage, bronchopulmonary dysplasia, necrotizing enterocolitis, severe retinopathy of prematurity and sepsis. CONCLUSION: Delayed cord clamping for 1 minute in preterm infants may be a safe and feasible method to increase initial hematocrit and reduce transfusion compared with umbilical cord milking.
