Purpose : There have been some reports on the prevalence of positive antineutrophil cytoplasmic antibody(ANCA) in Henoch-$Sch{\ddot{o}}nlein$ purpura(HSP), but the results were conflicting. We performed this study to evaluate the clinical significance of ANCA(c-ANCA and p-ANCA) in Korean children with HSP. Methods : The medical records of 30 patients(13 boys and 17 girls) aged 6.0$\pm$1.9(5-12) years with a clinical diagnosis of HSP based on the EULAR/PReS criteria were reviewed retrospectively. From the years 2007 to 2008, the sera from children with acute HSP were tested for antineutrophil cytoplasmic antibodies(ANCA). The target antigens of these autoantibodies are proteinase 3(c-ANCA) or myeloperoxidase(p-ANCA). Results : Palpable purpura was seen in all 30 patients(100%), abdominal pain in 20(67%), arthralgia in 17(57%), and renal involvement in 11(37%). Laboratory findings showed leukocytosis in 4 patients(13%), thrombocytosis 18 in(60%), and elevated erythrocyte sedimentation rate in 18(60%). Anti-streptolysin O titers were elevated in 7% of the patients and no patient showed elevation of serum IgA level. The sera from 29 patients were negative for c-ANCA and p-ANCA by indirect immunofluorescence, but only one patient had weakly positive results, which became negative at follow-up. Conclusions : We conclude that c-ANCA or p-ANCA is not an important serologic marker in children with HSP, because it was neither diagnostically nor immunologically specific in children with HSP. These results suggest that ANCA are not involved in the pathogenesis of HSP in children.

Purpose: The purpose of this study was to evaluate the long term outcome and the factors contributing to treatment outcome for chronic functional constipation in children. Methods: Sixty three children were enrolled who had chronic functional constipation and could be followed by telephone contact. They were treated at the Bucheon Soonchunhyang Hospital for more than 1 month and observed from March 2001 to June 2005. We analyzed the clinical features, symptoms and signs, as well as the course and results of treatment. Results: The male to female ratio was 35 (55.6%) : 28 (44.4%). The mean age at the onset of symptoms and diagnosis was $21.1{\pm}23.5$ (1.9~84.0) months and $47.1{\pm}34.2$ (6.9~138.0) months, respectively. The mean defecation frequency before treatment was $3.2{\pm}2.3$ (0.5~10.0) times per week. The symptoms associated with constipation were as follows: soiling 34 (54.0%) which was more common in males than females, large stools in 30 (47.6%), decreased bowel movements less than three times a week in 20 (31.7%), straining during defecation in 19 (30.2%) and retentive posturing 19 (30.2%). The mean duration of follow-up was $34.2{\pm}14.6$ (3.6~60.0) months and 44 (69.8%) patients had their symptoms resolve ("success") and 19 (30.2%) were not resloved ("fail") from the constipation. The time for recovery from soiling, straining during defecation and retentive posturing after treatment was $4.3{\pm}2.4$ (1.0~36.0), $5.0{\pm}1.4$ (0.8~36.0) and $5.0{\pm}3.1$ (1.0~36.0) months, respectively. A relapse of the constipation occurred in 15 (23.8%) patients, 9 (60%) boys and 6 (40%) girls. The time to relapse after cessation of treatment was $2.9{\pm}1.9$ (1.0~6.0) months and the only risk factor associated with relapse was the initial duration of treatment. Conclusion: Most of the patients had resolution of symptoms within five months after treatment; relapse occurred within three months after the interruption of treatment. The duration of treatment was important for recovery and for the prevention of relapse in the constipated children. Thus a long term maintenance of therapy and follow-up is necessary for chronic functional constipation in children.

A study on the seafood consumption was conducted from 1902 adolescent students (1110 boys and 792 girls) attending middle or high school to assess the attitude and degree of satisfaction for seafood being served in the school lunch program and ultimately to promote greater seafood consumption. A self-administered questionnaire was used to record the results. The results were as follows: Sixty percent of the respondents appeared to like or not to be reluctant to seafood. The main reasons for favoring seafood were its nutritious effect and taste. On the other hand, the reason for disliking seafood was due to its peculiar smell. In terms of cooking methods, the subjects preferred raw, fried, and grilled seafdod, whereas they disliked salt-fermented, seasoned and stewed dishes. The highly preferred seafood were crab, shrimp, tuna and squid. Only 6.6% of middle school students (MS) and 3.7% of high school students (HS) liked the seafood served in school lunch program, whereas the others responded 'so so'or disliked it. The reasons for disliking seafood being served in school lunch program were poor taste (14.7% of MS, 23.5% of HS), lack of freshness(6.3% of MS, 13.9% of HS) and unattractable cooking methods(3.4% of MS, 11.1% of HS). To promote seafood consumption in school lunch program, subjects anticipated the taste improvement (37.7% of MS, 48.5% of HS), use of a variety of seafood (19.8% of MS, 24.0% of HS) and cooking methods(12.6% of MS, 22.4% of HS). Above results suggested that further efforts are needed to provide preferred cooking methods and seafood items as a way of increasing seafood acceptability.

Between March 1999 and January 2000, 82 boys with the diagnosis of inguinal hernias (12 bilateral and 70 unilateral hernias), underwent Ultrasound (US) examination of both sides of the groin, a total of 164 inguinal imaging prior to surgery. The patients ages ranged from 3 days to 12 years with a mean of 32.6 months. Ninty four examinations were on the clinically symptomatic side and 70 were on the asymptomatic side. The US criteria for the diagnosis of an inguinal hernia were as follows: 1) visceral hernia, the presence of bowel loops, or omentum in the inguinal canal, 2) communicating hydrocele, the presence of fluid in the processus vaginalis, 3) widening of patent processus vaginalis at the level of internal inguinal ring. The width of patent processus vaginalis at the level of internal inguinal ring over 4 mm is considered an occult hernia. Among the 94 symptomatic groins, US findings showed 31 (33%) visceral hernias, 18 (19%) communicating hydroceles, and 38 (41%) widening of the internal inguinal ring, and 7 (7%) groins without abnormalities. In 70 asymptomatic groins, there were 4 (6%) visceral hernias, 5 (7%) communicating hydroceles, 11 (16%) widening of the internal inguinal ring, and 50 (70%) groins without abnormalities. Among the 70 asymptomatic groins there were US abnormalities in 20 (28%). One hundred and seven groins with positive US findings were surgically explored. Among 107 operated sites, the operative findings were compatible with the US diagnosis in 104, a sensitivity for US of 97.2%. In patients with US findings of widening of internal inguinal ring (>4 mm), there was patent processus vaginalis in 36 out of 38 symptomatic groins and 10 of 11 asymptomatic groins. The sensitivity of US to the operative findings in widening of internal inguinal ring was 93.8%. For visceral hernia and communicating hydrocele, the sensitivity of positive US findings was 100%. Ultrasonography for inguinal hernias appears to be a rapid, reliable, and noninvasive screening diagnostic tool with high positive specificity. Therefore, we recommend the use of US as a routine diagnostic tool in pediatric patients with inguinal hernias and hydroceles.

Science drama can be an useful tool for understanding the nature of science, Science-Technology-Society relationship by providing indirect experiences to young students. Specific science concept and knowledge can also be learned with high interests. In this study, to explore the usefulness of science drama in elementary science lessons, two scripts of science drama and lesson plans were developed and implemented. Six step model for science drama lessons was also suggested. One was 'Manhattan Project' which dealt with social, ethical responsibility in using science & technology (science argument drama), and the other was 'Mom, My blood type is O' which explained the heredity of blood type (science concept drama). Two teachers were asked to write their journals during preparation and implementation of science drama lessons, and the lessons were observed by the researcher and video taped for analysis. Some students were interviewed just after the lessons by the teacher and all students were asked to write their impressions, change of their thought, what is leant etc. Overall responses of students and teachers on the two science drama lessons were very positive, 'Mom, My blood type is O' got more positive responses, and girls were more positive than boys. Some students anticipated another science drama even suggest topics for it. 'Mom, My blood type is O' was successful in making students (grade 3) understand the knowledge related with heredity of blood type (71% of the students got perfect answer). In 'Manhattan Project' students (grade 5) perceived more diverse location of responsibility after the lesson, but the danger and harmfulness of atomic power was embossed. This implied the need of more careful planning for the relevant learning activities before and after the play of science drama.Two teachers perceived the science drama as a new, useful tool for some subject which is hard to deal with by other teaching method. They were also satisfied with students' high interest and engagement during the science drama lessons but the extra time and effort for the lessons were pointed out as a main difficulties.

The aim of this study was to analyze the dental caries of chilren's deciduous teeth in relation to their mothers' socioeconomic factors and their oral health beliefs to increase the effect on children's oral health. One hundred seventy four children and their mothers were selected for the study. The children were 5 and 6 years old in children house in Kun-san, Korea. Research was conducted by oral examination, their mothers' socioeconomic factors and dental health belief model. The finding of analysis can be summaried as follows; In regard to the caries in deciduous teeth status, the five-year-old boy children's dft index was 3.39 and that of the girls of the same age was 2.76. The dft index of the boys of six was 3.86 and that of the girls of the same age was 3.27. The five-year-old boy children had the highest df rate(81.8%), and their dt rate was more than their ft rate. But for the six-year-old girl children, ft rate was higher than dt rate. For the five years old, the boy children's ft rate was significantly higher than that of the girls(p<0.05). Concerning the caries in deciduous teeth states by socioeconomic factors, their oral health status was significantly different according to mother employment and householder age. The df rate of the preschoolers with working mothers(84.7%) was significantly higher than that of those with nonworking mothers(66.7%)(p<0.05). The dft index of the group whose households were over forty was highest with 4.07, followed by the children of the households aged 35 to 39 with 3.83, those of the households aged 25 to 29 with 3.33, and those of the households aged 30 to 34 with 2.15. The difference between the groups was significant(p<0.05). As to the difference of maternal dental health beliefs by maternal socioeconomic factors, households educational background and whether to live with parents or parents-in-law under the same roof made a significant difference to maternal oral health beliefs. The mothers whose households were college graduates or better-educated were stronger in oral health susceptibility and seriousness(p<0.01, p<0.05). The salience was recognized more by those who lived with parents or parents-in-law than by the others who didn't(p<0.05). The dft index of the preschoolers was related to maternal dental health beliefs. That was lower when their mothers perceived dental health benefit better.

The purpose of this study was to assess the relationship that adolescent stress perception level has with dietary habits and oral health behaviors in high school students. A survey of high school students in some areas of the Jeollabuk-do province of South Korea was conducted. Five hundred fourteen survey responses were used in the final analysis. As a result of the questionnaire survey, the following conclusions were obtained. The highest stress type was indicated to be academic stress (mean${\pm}$standard deviation [SD], $3.09{\pm}0.89$). The next was shown to be home (family) stress (mean${\pm}$SD, $2.85{\pm}0.84$). The possibility of using a dental clinic was indicated to be less in girls than boys (p<0.001). Regarding subjective oral health behavior, the possibility of visiting a dental clinic was low in those who thought that their own oral health condition was not good or moderate (p<0.05). Also, it was shown that the higher stress led to the higher possibility of visiting a dental clinic (p<0.01). Students with higher grades had a in the upper ranks were indicated to have high possibility of having a regular meal (p<0.01). Higher stress led to the significantly higher possibility of eating cariogenic food (p<0.01). Students with median grades had a high possibility of eating cariogenic food (p<0.01), while students with higher grades had a low possibility of eating cariogenic food (p<0.05). These resultss show that stress perception level influences dietary habits and oral health behaviors. Thus, there is a need to develop a program in high scholls to promote the physical and mental health of students to relieve stress. Substantial and systematic oral health education is thought to be likely needed to develop desirable dietary habits.

The purpose of this study was to develop a nutrition education curriculum with teacher's guide which includes discretionary activities for obese children. A survey was carried out to investigate the recognition of body image and food behaviors according to the obesity index (mild, moderate, severe) in school children (4~6th grade, 158 boys and 60 girls) who were selected based on a physical examination in May, 2006 in the Gyeongnam province. Next, a nutrition education curriculum with teacher's guide was developed on the basis of the findings from the survey and from preceding researches. The results are summarized as follow. The results of this study showed the existence of some nutritional problems such as overeating, prejudice, skipping meals, snacking patterns, etc, which indicate the need for nutritional management for obese children. Most overweight children (80.3%) showed the most interest in the nutrition education program, particularly with regards to dieting for weight control (64.7%). The developed nutrition education curriculum consisted of 8 main subjects and 13 subtitles. The curriculum was prepared for 13 lessons and included songs and singing, making-up lyrics, games about nutrition, discussions of the experience of eating (satiety, thirst, hunger), debates on dietary habits, writing and others to promote the interest for learning. We aimed to develop this program in an attempt to improve the dietary habits of obese school children. This is very important because once a dietary habit is formed in adults, it is difficult to change and the best adjustable stage is during childhood. Therefore, early nutrition education during elementary school can change and build-up the awareness of health in young elementary school children.

This study was designed to examine the aerobic capacity and ventilatory response during an incremental exercise in elite high school cyclists. Twelve boys ($17{\pm}1\;yr$, $175{\pm}5\;cm$, $70{\pm}9\;kg$) participated in anthropometric measurements, incremental exercise testing, and pulmonary function tests. During incremental exercise testing using a cycle ergometer, their maximal oxygen uptake ($VO_2max$), maximal power output, ventilation, ventilatory equivalents for oxygen ($V_E/VO_2$) and carbon dioxide ($V_E/VCO_2$), respiratory rate, and tidal volume were measured. Time variables such as inspiratory time (Ti), expiratory time (Te), breathing time (Tb), and inspiratory duty cycle (Ti/Tb), as well as inspiratory flow rate ($V_T$/Ti) were assessed. Pulmonary function of vital capacity (FVC), forced expiratory volume in one second ($FEV_1$), $FEV_1$/FVC, and peak expiratory flow were evaluated. Their $VO_2max$, maximal heart rate, and Wmax were $57.5{\pm}3.9\;ml{\cdot}kg^{-1}{\cdot}min^{-1}$, $194.1{\pm}8.6\;beat{\cdot}min^{-1}$, and 452 W, respectively. $VO_2max$ was not related to any anthropometric parameters. Most ventilatory variables progressively increased with exercise intensity. As intensity increased, Ti, Tb, Tb decreased while Ti/Tb was maintained. Below an intensity of 250 W, height, weight, body mass index, and body surface were highly correlated with $V_T$/Ti and Ti/Tb (p<0.05). Collectively, $VO_2max$ appeared to be lower than adult cyclists, suggesting a different pattern of ventilatory control as age advances. Morphological characteristics were not related to $VO_2max$ in the population. Time variables of ventilatory response seemed to be related only at an exercise intensity level of less than 250 W. $V_T$/Ti may be related to exercise endurance capacity, but Ti/Tb was similar to adult cyclists.

This study is aimed at providing the variables associated with adolescent compliance In orthodontic treatment, and identifies the salient predictors of cooperative behaviors over the course of treatment. Orthodontic attitude scale, orthodontic locus of control scale and demographics data were obtained for 60 adolescent orthodontic patients who had been in treatment a minimum of 10 months. This data was then analyzed in relation to their sex, school age and treatment compliance. The following results were obtained. 1. The scoring of external-powerful others-parents, subscale of the Orthodontic Locus of Control scale, found a statistically significant difference between sex differences (p<0.05). The score of boys was higher than that of girls. 2. The external-powerful others-parents score from the Orthodontic Locus of Control scale showed a significantly positive correlation (p<0.05) with the level of compliance. 3. The salient factors associated with compliance were the adolescent patients' own cognition and decisions. 4. There was a statistically significant correlation between the length of treatment and patient compliance (p<0.05). Thus, there was a substantial decrease in the cooperation of orthodontic patients over time. 5. Other independent variables including age, sex, family environment, religion, academic standing, parents' occupation and education, and brushing frequency were investigated and did not yield any significant relationships. Patient compliance is a critical factor in the efficacy of orthodontic treatment. Individuals vary greatly in their perceptions and attitudes of orthodontic treatment, sociodemographic environments and personality characteristics. In assessing the level of compliance attainable by each individual patient it is advisable To pay sufficient attention not only to the technical matters but also to the psychologic aspects of the treatment progress.
