Purpose : Forward pulmonary blood flow may be absent in some neonates with Ebstein's anomaly by anatomical or functional pulmonary atresia in association with the elevated pulmonary vascular resistance, patent ductus arteriosus and tricuspid regurgitation. We reviewed the presentation and outcomes of symptomatic neonates with Ebstein's anomaly focusing on the pulmonary atresia. Methods : Clinical presentation and outcome of 15 symptomatic neonates with Ebstein's anomaly seen at Asan medical center from 1998 to 2004 were reviewed. Results : Ten(67%) of 15 patients showed no forward pulmonary blood flow and 6 of them had functional pulmonary atresia. $O_2$ saturation and pH were lower and cardiothoracic(CT) ratio in chest radiography was more increased in the patients with pulmonary atresia than in the patients without pulmonary atresia(P<0.05). pH and CT ratio were not different between the anatomical and functional pulmonary atresia group, but $O_2$ saturation was lower in functional atresia group(P<0.05). 13 patients(87%) were managed with $PGE_1$. 4 of 6 patients with functional pulmonary atresia were treated with inhaled nitric oxide. Surgery was performed in 1 of 5 patients without pulmonary atresia and in 8 of 10 patients with pulmonary atresia during follow-up period(mean 37 months). 3 patients(20%) died and none of patients without pulmonary atresia died. Conclusion : We found that most symptomatic neonates with Ebstein's anomaly had functional or anatomical pulmonary atresia. The neonates with Ebstein's anomaly who had no forward pulmonary blood flow were more symptomatic and needed surgery earlier. Further studies will be needed to distinguish effectively functional and anatomical pulmonary atresia and to manage appropriately neonates with functional atresia.

Purpose : Short attacks of headache are present in the pediatric age group. Short-lasting headaches (SLH) have been infrequently reported in children and adolescents. This study aims to assess the prevalence, clinical characteristics, treatment, and prognosis of short-lasting headaches in children and adolescents. Methods : One hundred twenty-three consecutive patients attended the Chosun University Hospital Headache Center between March 2006 and July 2007. Among 123 headache patients, 44 patients with one key criterion, namely, recurrent headaches episodes of a few seconds to less than 30 minutes, were selected. Results : Of the 123 headache patients, 44 (35.8%, males 18, females 26) had SLH. The mean age was 9.24 years (range 2.3-14.2). The mean headache frequency was $11.50{\pm}10.30$ per month, mean severity was $4.86{\pm}1.36$ out of 10, and the mean PedMIDAS score was $7.97{\pm}17.51$. SLH was significantly more common in children <6 years old (10/22, 45.5%) than in ${\geq}6$ years old (34/101, 33.7%) (P=0.015). The nature of pain was pressure in 30.2%, stabbing in 27.9%, throbbing in 18.6%, and dull in 11.7%. In 52.4% patients, the pain occurred in the front, one side of the temple in 28.5%, both sides of the temple in 7.1%, and back in 4.8% patients. The duration of attacks was <6 minutes in 38% and ${\geq}6$ minutes in 61.4%. The intensity of the pain was 4-6 out of 10 in 75.0%, in 13.6% 1-3, and in 11.4% 7-10. Treatment was significantly effective in reducing the frequency, duration, and severity of headaches and the PedMIDAS score after 3 months (P<0.05). Conclusion : Short attacks of headache are common (35.8%) in children and adolescents. These are difficult to classify according to International Headache Society criteria. The outcome, after a period of 3 months to 2 years, was favorable in most patients. Further studies are needed to gather more data and to obtain a better description of these forms of headache in the pediatric group.

The purposes of this study are to analyze abnormal dilatation of the extrahepatic bile ducts by using transabdominal ultrasound, to confirm the existence of bile ducts diseases and their interrelationship, and for it to give a new theoretical basis for the technical access to extrahepatic bile ducts, upon which to analyze the ripple effects of the scan training. After teaching technical access process based on the new theory about extrahepatic bile duct to the thirty students who are studying ultrasonography, we allocated three hours per one student (30 mins ${\times}$ 6 times) to focus on the training of scanning skill. Training has been performed by one-to-one method. For evaluation, all the students have to perform the scans on (1) confluence of the right and left hepatic ducts (extrahepatic bile ducts and cystic duct), (2) the suprapancreatic bile duct, (3) the intrapancreatic bile duct, (4) intrapapilla Duct, based on the clearly divided concept. The existing training and methods have had low confidency about transabdominal ultrasonography of the extrahepatic bile duct and had limitation with which they could image only the suprapancreatic bile duct. The evaluation after finishing the train based on the new theory, however, all the students (30students) can access to (1) confluence of the right and left hepatic ducts(extrahepatic bile ducts and cystic duct), (2) the suprapancreatic bile duct objectively. 24 students can access to (3) the intrapancreatic bile duct and only one student can even make an image for (4) the intrapapilla Duct Though the evaluation on extrahepatic bile duct has to be performed with multi-sided method considering intrahepatic cause, bile duct cause and pathophysiological cause, only if we can image the extrahepatic bile duct to ampular of Vater objectively and confidently, we can greatly reduce invasive procedure such as ERCP, which is for the purpose of simple differential diagnosis and painful to the patients. Therefore if we concentrate on the scanning train based on the new theory to raise the confidency about ultrasonography, the effect will be doubled.

Purpose : This study was performed for the purpose of finding causative organisms and clinical features of septic arthritis or acute osteomyelitis in children. Methods : The study involved a retrospective review of the medical records of 63 microbiologically confirmed cases of acute pyogenic arthritis and osteomyelitis. All of the cases were brought about by community-associated infections and managed at the Seoul National University Children's Hospital or Seoul National University Bundang Hospital from June 2003 to July 2009. Results : The median age of all cases was 60 months and there were 35 males and 28 females. Major involved joints included the hip joint (15 cases), knee joint (7 cases), shoulder joint (4 cases), and elbow joint (4 cases). Also, major involved bones included the femur (20 cases), tibia (13 cases), humerus (7 cases), and radius (7 cases). Staphylococcus aureus was the most commonly identified causative organism, accounting for 49 cases (77.8%). Of the 49 isolates of S. aureus, methicillin-resistant S. aureus (MRSA) accounted for 8 cases (16.3%). Group B streptococcus spp. (GBS) and Salmonella spp. accounted for 3 cases, respectively. Nafcillin or cefazolin was often prescribed as an initial empirical antibiotic. There were 9 cases that were managed by a regimen that included vancomycin as the first choice. Fifty four cases (85.7%) recovered without any complications. Methicillin-sensitive S. aureus (MSSA), responsible for 41 cases, caused chronic complications in 3 cases. Of 8 cases caused by MRSA, 1 case showed chronic complication. There were no fatal cases. Conclusion : S. aureus remains the most common organism causing acute pyogenic arthritis and osteomyelitis of childhood acquired in the community. The high prevalence of methicillin resistance among S. aureus should be considered carefully in the selection of initial empirical antibiotics.

Purpose: This study analyzed a small outbreak of measles at a single hospital located in northern Gyeonggi-do in 2013. Methods: We reviewed the medical records of measles patients at The Catholic University of Korea Uijeongbu St. Mary's Hospital from August to October, 2013. Results: Fifteen children were confirmed to have measles by RT-PCR and serum IgM test; 1 neonate, 11 infants, and 3 toddlers. None of the patients had received Measles-Mumps-Rubella vaccination. All patients showed B3 type in viral genotyping. Nine children (60%) had been exposed to measles during treatment for other diseases in the pediatric ward. Incubation period was between 8 and 15 days. Fever started at a median 10 days after exposure and persisted for a median of 8 days. Rash showed at a median 13 days after exposure. Respiratory complications were observed in 40% of patients. Diarrhea developed in 53% of patients. Conclusion: Although measles has been well-controlled due to the high rate of vaccination coverage, it is possible to have an outbreak at any given time, especially in infants. We must learn from this outbreak, and remain fully aware of the possibility of reemergence and provide proper management, including vaccination or immune globulin administration, to infants exposed to measles. Reevaluation of serum IgG titer of neonates, infants, and pregnant women may be the first step to prevent further outbreaks.

Purpose : This study was performed to report the diagnosis and treatment of nephrotic syndrome manifesting in the first year of life. Methods : We retrospectively reviewed the clinical data with chart review in 7 patients who were diagnosed as nephrotic syndrome manifesting in the first year of life from 1996 to 2007. Results : Three patients had congenital nephrotic syndrome, the other 4 patients had infantile nephrotic syndrome. Their ages ranged from birth to 11 months and male to female ratio was 1 to 6. Renal biopsies were done in 6 patients. One patient had Finnish type congenital nephrotic syndrome, 2 patients had diffuse mesangial sclerosis, 2 patients had focal segmental glomerulosclerosis and 1 patient had minimal change disease. Genetic analyses of NPHS2, PLCE1, and WT1 were done in 4 patients and 2 of them had WT1 mutation. Among 3 patients with congenital nephrotic syndrome, 1 patient was diagnosed as congenital nephrotic syndrome of Finnish type and the other 2 patients were diagnosed as Denys-Drash syndrome. All of the patients with congenital nephrotic syndrome died due to sepsis. Among 4 patients with infantile nephrotic syndrome, 2 patients died and 1 had remission, another patient progressed to end stage renal disease. Conclusion : Most of nephrotic syndrome manifesting in the first year was hereditary renal disease. Patients with nephrotic syndrome manifesting in the 3 month of life had poorer prognosis and needed more aggressive management including early dialysis and renal transplantation might be considered compared with infantile nephrotic syndrome. Further genotype-phenotype correlation studies are needed.

The symptom expressions such as yellowish and mosaic spots in overwintering barley have been considered to be a damage by cold or water. However, it had revealed that the symptom expressions were caused by viruses throughout three year nationwide surveys. Barley yellow mosaic virus (BaYMV), Barley mild mosaic virus (BaMMV), and Soil-borne wheat mosaic virus (SBWMV) was detected in 2001-2003 and Barley yellow dwarf virus-MA V (BYDV -MA V) from field samples collected on March in 2003. The results of investigation showed that the incidence of BaYMV was more than 70％ and that of BaMMV and SBWMV was 15.7-37.4％ and 0.7-10.1 ％ in three year surveys, respectively. The incidence of BYDV-MAV was approximately 1 ％ in 2003 only. The distribution of BaYMV was relatively uniform throughout barley fields in Korea, but the incidence of the virus in Gyunggi Province was as low as 19％ compared to 65-85％ in the rest of regions. On the other hand, 70％ of BaMMV was found to be in the west south regions of Korea, Jeonbuk and Jeonnam Provinces. Taken together, both BaYMV and BaMMV were thought to be dominant casual agents in overwintering barley by either single or mixed infections. Previous survey data for BaYMV from 1994 to 1996 indicated that the incidence of the virus was approximately 40％ in Jeonbuk, Jeonnam, and Gyungnam Provinces. Thus, comparing with the results from the recent nationwide survey, the incidence of BaYMV had been rapidly increasing in overwintering barley fields in the southern part of Korea.

The aim of this study was to survey the perceptions of the elementary school teachers on the smallscale chemistry(SSC) following its training session. The teachers participating in the survey were 266 teachers in the Gyeongnam province. They were given a questionnaire that focused on the nine areas of the SSC: Needs for the teacher training and its application, its benefits, issues of safety and danger as well as treatment of environmental pollution, its economic efficiency and the development of investigative skills. The designed questionnaire was checked by an authority, and the responses to each question were tallied and analyzed. The results are as follows. The biggest problems of the traditional experimental methods as rated by the teachers were, in the order of importance, the preparation time, the legal liability of teachers for the safety and accidents, financial issues, disposal of the experimental wastes and the lack of relevant data. Since most of the teachers had not experienced the SSC lab programs in the field, they responded positively to the questions of need for its introduction and training. The implementation of the experimental SSC lab programs should proceed in the following order: introduction into the textbook, teacher training program, after-school education and the invitation of instructors. The most useful materials for the SSC program were CDs, videos, books and various printed materials, in that order. The responses regarding benefits of the SSC program included its simplicity, convenience, time savings, diversity, qualitative and quantitative aspects, integration into the regular class and use of toys. In particular, the teachers mentioned the increased safety due to the small amount of experimental reagents needed and the durability of plastic instruments. The familarity from the use of everyday tools as well as easy access to and the low-cost of the instruments were other important benefits. The teachers in general rated the educational content of the program highly, but many also found it to be average. Some pointed out the lack of sufficient discussion due to the individual or pair groupings as a potential shortcoming. The potential for development of problem solving ability and improvement of skills was rated positively. The number of teacher who rated the development of creativity positively was just over the half. As for the area of improving investigative skills, many found its assessment difficult and confusing because of the lack of its systemic definition and categorization. Based on the findings of this study, I would like to recommend the application and a wider dissemination of the small-scale chemistry lab program into the elementary school science curriculum.

To examine the EC model in a culture medium, basic culture medium of Rush (2005) and EC model of Robinson and Strokes (1959) were applied analyzing the equivalence ion total amount, the EC variable of cation and anion. Following the experiential translation by Steiner (1980), 130 optimized domestic and foreign culture media for crop growth were utilized, and estimated EC model was also demonstrated. Results from basic culture medium of Rush (2005) suggests an estimated EC by equivalence ion total amount and high reliable regressive model with 0.96 y = 1.33x - 0.23 of 0.96 as value $R^2$. It was found out that the change in concentration of positive ion and anion did not differ significantly with the increase and decrease of EC, however, there occurred a slight variable range. The change brings about a bigger anion influence than the previously reported positive ion, seemingly like those based on nitride ion and sulfur ion. The above EC estimated models confirmed that with optimized 130 domestic and foreign culture media for crop growth, the value derived will be as follows: $R^2$ = 0.98 with y = 1.23x - 0.02. In addition, the contour analysis of positive ion and anion for EC, with popularly known concentration range of EC $1.5-2.5dS{\cdot}m^{-1}$ reveals an equivalent of more than $11meq{\cdot}L^{-1}$ for positive ion and $15meq{\cdot}L^{-1}$ for anion. On the other hand, the left bottom, low concentration $1.5dS{\cdot}m^{-1}$ and the right above, high concentration $2.5dS{\cdot}m^{-1}$, for both positive ion and anion existed differently in a proper culture medium concentration. This study adapted variables of both positive ion and anion of EC simultaneously, unlike in the previous culture medium by ion ratio in mutual ratio of Steiner (1980), and offers an EC model that can estimate levels or positive ion and anion in proper concentration, EC $1.5-2.5dS{\cdot}m^{-1}$, with distributed features of ions.
