Summary : This study was designed to identify the difference in temperament, parent-adolescent's goodness of fit and behavioral problems between early-adolescent high risk group which can be divided into subgroups (ADHD-I and ADHD-HI/C) and normal group. Method : Subjects of this study were students of a Boy's Middle School and their parents. ADHD high risk group was determined by using three rating scales of ADHD behavioral symptoms : 1. Korean-ADHD Rating Scale, 2. Abbreviated Conners Parents Rating Scale, 3. Conners-Wells' Adolescent Self-Report Scale. Final research was based on the subjects including 25 people in ADHD-I high risk group, 70 ADHD-HI/C high risk group, 70 in normal group. Revised Dimensions of Temperament (DOTS-R) was used for students to assess their temperament, while DOTS-R : Ethnology for parents to access environmental demands. Goodness of fit between parent and adolescent was figured out by results of the two scales. Korean Youth Self Report (K-YSR) was used to examine behavioral problems. Results : When it comes to temperament of adolescents, ADHD-HI/C high risk group was found to be associated with higher scores on general activity level. In contextual parent demand to adolescent, ADHD-HI/C parents showed higher level of demands in general activity than other groups, and lower expectation of positive mood than ADHD-I parents. In parent-adolescent's goodness/poorness of fit, the research found out that ADHD-I and ADHD-HI/C had lower level of fit on pesitive/negative mood than normal group and indicated that ADHD behavioral symptoms connected with poorness of fit in emotional relationship between adolescents and their parents. In behavioral problems, ADHD-HI/C high risk group had severe externalizing and internalizing problems distinctly. It had more severe in externalizing problems than ADHD-I, while there were no differences in internalizing problems between the two subgroups. Conclusion The two ADHD subgroups in high risk adolescents had differences on temperamental activity level and on goodness of fit about positive mood. In addition, they had different patterns in externalizing/internalizing problems.

The most common cause of obstructive sleep apnea syndrome (OSAS) in childhood is adenotonsillar hypertrophy. Adenotonsillectomy improves the symptoms quite well in most cases. However, some patients could experience the OSAS again after adenotonsillectomy, who might have several risk factors such as incomplete operation, misdiagnosis, combined anatomical malformation, sinusitis or chronic allergic rhinitis, obesity, initial severe OSAS, and early onset OSAS. We report a case of 11-year-old obese boy who presented with snoring for several years. He was obese with body mass index (BMI) of $26.3kg/m^2$ and also found to have fatty liver by ultrasonogram. Initial polysomnography (PSG) showed that he met the criteria of severe OSAS with the apnea-hypopnea index (AHI) of 70.5. He underwent adenotonsillectomy and symptoms improved immediately. Four months later symptoms were relieved with AHI of 0, but 1 year after the adenotonsillectomy he started to complain snoring again and the subsequent PSG results showed that OSAS has relapsed with AHI of 43. Paranasal sinus X-ray and physical examination showed sinusitis and re-growth of adenoid. Obesity was proved not to be a contributing factor because his BMI decreased to normal range ($23.1kg/m^2$) after diet control and regular exercise. Also, liver transaminase was normalized and fatty liver was disappeared on follow-up abdominal ultrasonogram. After treatment of sinusitis, symptoms were relieved with decreased AHI (8.5). This case suggests that simple adenotonsillectomy might not be the end of OSAS treatment in childhood. Patients who had adenotonsillectomy should be followed by subsequent PSG if symptoms recur. It is also important to be aware of risk factors in the recurrent OSAS for the proper intervention according to the cause.

The present. study reports four cases of congenital heart diseases, who received open heart surgery by the Sarn's Heart-Lung-Machine in the department of Thoracic Surgery, Hanyang University Hospital during the period between July 1975 and May 1976. The Heart-Lung-Machine consisted of the Sarn's five head roller pump motor system (model 5000), heat exchanger, bubble trap, the Rygg-Kyvsgaard oxygenator, and monitors. The priming of pump oxygenator was carried out by the hemodilution method using Hartman's solution and whole blood. Of the four cases of the heart diseases, three whose body weight were below 30kg, received the partial hemodilution priming and the remaining one whose body weight was 52kg received the total hemodilution priming with Hartman's solution alone. The rate of hemodilution was in the average of 60.5ml/kg. Extracorporeal circulation was performed at the perfusion flow rate of the average 94.0ml/kg/min, and at the moderate hypothermia between 35'5"C and 30'5"C of the rectal temperature. In the total cardiopulmonary bypass, arterial blood pressure was anged between 30 mmHg and 85 mmHg, generally maintaining over 60 mmHg and venous pressure was measured between 4 and $23cmH_2O$, generally maintaining below $10cmH_2O$. The first case: The patient, a nine year old girl having the symptoms and physical signs typical to cardiac anomaly was definitely diagnosed as isolated pulmonary stenosis through the cardiac catheterization. There was, however, no cyanosis, no pathological finding by X-ray and E.C.G. tracings. The valvulotomy was performed through the arteriotomy of pulmouary artery under the total cardiopulmonary bypass. Postoperative course of the patient was uneventful, and murmur and the clinical symptoms disappeared. The second case: A 12 year old boy with congenital heart anomaly was positively identified as having ventricular septal defect through the cardiac catheterization. As in the case with the first case, the patient exhibited the symptoms and physical signs typical to cardiac anomaly, but no pathological abnormality by X-ray and E.C.G. tracings. The septal defect was localized on atrioventricular canal and was 2 by 10 mm in size. The septal defect was closed by direct simple sutures under the cardiopulmonary bypass. Postoperative hemodynamic study revealed that the pressure of the right ventricle and pulmonary artery were decreased satisfactory. Postoperative course of the patient was uneventful, and murmur and the clinical symptoms disappeared. The third case: The patient, a 19 year old girl had been experienced the clinical symptoms typical to cardiac anomaly for 16 years. The pink tetralogy of Fallot was definitey diagnosed through the cardiac catheterization. The patient was placed on an ablolute bed rest prior to the operation because of severe exertional dyspnea, fatigability, and frequent syncopal attacks. However, she exhibited very slight cyanosis. Positive findings were noted on E.C.G. tracings and blood picture, but no evidence of pathological abnormality on X-ray was observed. All of the four surgical approaches such as Teflon patch closure (3 by 4cm in size) of ventricular septal defect, myocardial resection of right ventricular outflow tract, valvulotomy of pulmonary valvular stenosis, and pericardial patch closing of ventriculotomy wound were performed in 95 minutes under the cardiopulmonary bypass. Postoperative hemodynamic study revealed that the pressure of the right ventricle was decreased and pulmonary artery was increased satisfactorily. Postoperative course of the patient was uneventful, and murmur and the clinical symptoms disappeared. The fourth case: The patient, a 7 1/4 year old girl had the symptoms of cardiac anomaly for only three years prior to the operation. She was positively identified as having acyanotic tetralogy of Fallot by open heart surgery. The patient showed positive findings by X-ray and E.C.G. tracings, but exhibited no cyanosis and normal blood picture. All of the three surgical approaches, such a myocardial resection of hypertrophic sight ventricular outflow tract, direct suture closing of ventricular septal defect and pericardial patch closing of ventriculotomy wound were carried out in 110 minutes under the cardiopulmonary bypass. Postoperative hemodynamic study revealed that the pressure of the right ventricle was decreased and pulmonary artery was increased satisfactorily. Postoperative course of the patient was uneventful, and the symptoms disappeared.

This study was designed to investigate lunch of the boy's and girl's middle school students in Busan. The survey was conducted from September 15 to September 30 in 2002. It was revealed that there is no difference in the scores measuring the knowledge In nutrition and the eating habit between male students and females. 10.6 % of the male students scored poor in the knowledge in nutrition, 38.2% fair 42.5% good and 8.7% excellent respectively while 4.1% of the female students scored poor in the same area, 31.6% fair, 52.1% good and 12.2% excellent respectively. The biggest number of both group of students scored good in their eating habit, the second biggest fair, the third biggest excellent and the least scored poor. Female students were reported to bring their lunch more than the male students do(p<0.05). And there was a significantly difference in the frequency of bringing lunch according to their knowledge in nutrition and their dietary attitude(p<0.001), but whether mothers have .jobs or not, mothers'educational background or monthly expenses for food didn't seem to make any differences. The intakes of nutritional elements except phosphorus and vitamin C are lower than RDA. The ratio of intakes of nutritional elements from lunch was 13∼14.1% of calcium, 17.9∼19.2% of vitamin A and 19.3∼19.6% of iron, showing a significant unbalance in nutritional intakes. Nutritional intakes had little relationship with the knowledge in nutrition and eating habit. The frequency of carrying lunch, energy intakes and phosphorus intakes had significantly relationship with each other. And the better the eating habit was, the more often the individual carried lunch.

The purpose of this thesis is to provide the framework of the health education curriculum on a school level which should be accomplishe in futrue and farthermore to establish the health education as a independent and regular course. The relation among the status in quo and the satisfaction degree of health education, the degree of the knowledge about health, the degree of the understanding of the health education and the degree of requirement for the health education curriculum has been analyzed in this paper. The research has been carried out through the questionnaire forms distributed to the girl students and the instructors at a few general senior high school and vocational senior high schools in Seoul, and the consequences are as follows : 1. As to the degree of understanding of the health education, it has been indicated that the health education should be performed one or two hours a week from the elementary school for all the boy and girl students by the experts trained in the departments concerned with health. 2. Concerning the degree of requirement for health education curriculum, the high school girl students have shown the need for first aid, sex education, environmental health, drinking, smoking, drug abuse, maternal and child health, industrial health, safety health, mental health, growth & development, epidemiology, the old health in the order named. On the other hand, the instructors have shown the need for drinking, smoking, drug abuse, sex education, maternal and child health, public health and industrial health also in the order named. The items having low degree of requirement are biostatistics, community health and health administration in case of the gril students and biostatistics, health administration and health economics in case of the instructors. 3. The status in quo and the satisfaction degree of the health education has proved higher in senior high school curriculums than in junior high school curriculums, and the most instructive course about health has turned out to be gymnastics in junior high school and the training course in senior high school respectively. 4. As to the degree of understanding of the health education in case of the girl students, the significance has been found between the health condition and the time for performing the health education, the monthly income and the objects for the health education, and the school records and the school hours per week. The significance has been shown only in regard to the school records in case of the degree of requriement for the health education curriculum. 5. The degree of requirement for the health education in case of the instructors has shown the significance between the teching career and the need for the health education. In addition, the degree of requirement for the health education curriculum has indicated significance with regard to sex and age. 6. The degress of the understanding of the health education according to the degree of knowledge about health and the degree of requirement for the health educatio curriculum have been all turned out to be statistically significant. 8. Among the factors which have an influence on the degree of the understanding of the health education, the recognition of the relation between the health course and the training course has significatly influenced the selection of the health education instructors. In additon, the understanding of the need for the health eduation has significantly influenced the objects for the instructors and the school hours, and the understanding of the need for establishing the health education course has significatly influenced the time for performing the health education.

Until now, the study of eye refractive error examination for high school students are a few report that in Korea. In particular, there is few report about the visual power for same group during several years. We compared the study of refractive error done this year with that reported three years ago at the same high school. From the these data, the distribution of ammetropia was investigated. The study of refractive error for high school students was also compared with those reported before for the Adults and the middle school student. When the visual power is refered to spherical equivalent, the 36% of the whole students examined above had emmetropia and the other part of them fumed out to be ammetropia which is classify to 60.6% belonged to myopia and 4.4% belonged to hyperpia. The ratio of myopia for this year students is increased in comparision with the students in 1995. The ratio of emmetropia for this year students is 7.4% higher, and the ratio of myopia for this year students is 4% higher, but the ratio of hyperopia is very lower than that for the adults in 1997. In the kind of refractive error, it is classified that a simple myopia is shown to highest ratio as a 28.6% of 1212 eyes examined, a compound myopic astigmatism to the next high ratio as a 22.4%, a simple myopic astigmatism as 14.4%, a simple hyperopic astigmatism as 3.1%, a mixed astigmatism as a 1.7%, a simple astigmatism as 1.2%, a compound hyperopic astigmatism as 1.2%, respectively. The percentage of an astigmatism is a 76.7% of total eyes examined if Cyl-0.25 Dptr is included to an astigmatism. On the other hand, The percentage of an astigmatism is a 45.6% of total eyes examined if Cyl-0.25 Dptr is excluded to an astigmatism. In the kind of astigmatism, the number of students had an astigmatism with the rule is about 4.5 times than that of astigmatism against the rule. From the result of comparision the right eye with the left eye, the right eye of the students had more a myopic refractive error than the left eye, which is same as adults' case, there is no difference in a refractive error between the boy students and the girl students.

Glycogen storage disease (GSD) and mucopolysaccharidosis (MPS) are both independently inherited disorders. GSD is a member of a group of genetic disorders involving enzymes responsible for the synthesis and degradation of glycogen. GSD leads to abnormal tissue concentrations of glycogen, primarily in the liver, muscle, or both. MPS is a member of a group of inherited lysosomal storage diseases, which result from a deficiency in specific enzymatic activities and the accumulation of partially degraded acid mucopolysaccharides. A case of a 16-month-old boy who presented with hepatomegaly is reported. The liver was four finger-breadth-palpable. A laboratory study showed slightly increased serum AST and ALT levels. The liver biopsy showed microscopic features compatible with GSD. The liver glycogen content was 9.3% which was increased in comparison with the reference limit, but the glucose-6-phosphatase activity was within the normal limit. These findings suggested GSD other than type I. Bony abnormalities on skeletal radiographs, including an anterior beak and hook-shaped vertebrae, were seen. The mucopolysaccharide concentration in the urine was increased and the plasma iduronate sulfatase activity was low, which fulfilled the diagnosis criteria for Hunter syndrome (MPS type II). To the best of the authors' knowledge, this is the first case of GSD and Hunter syndrome being identified at the same time.

The aim of this study was to test whether metric measurements of crown length, root length and apex width during tooth development could be a better basis for correlation with age than the classical methods based on subjective estimations of various stages of tooth development. Panoramic radiographs of 120 children, aged 7 to 9 years, were collected from the department of the pediatric dentistry of Chonnam National University Hospital, Korea. The methods of Mornstad was used to estimate age. The structures measured were crown length root length and apex width in panoramic radiographic. The results were as follows : 1. In the boys, it showed higher correlation between lower 2nd molar crown length, lower 1st molar root length or lower 1st permolar apical width and age. In the girls, it showed higher correlation between lower 2nd premolar crown length, lower 2nd molar root length or lower 1st molar apical width and age. 2. With the aid of a multiple regression model, a linear relationship between some of these distances and age was shown. Boy(months) = 43.958 + lower 2nd molar crown length ${\times}$ 4.392 + lower 1st molar root length ${\times}$ 2.255 - lower 1st permolar apical width ${\times}$ 2.046, Girl(months) = 75.213 + lower 2nd premolar crown length ${\times}$ 3.910 lower 2nd molar root length ${\times}$ 2.280 - lower 1st molar apical width ${\times}$ 6.217 Age was estimated in boys and girls using the mathematic model ; the mean difference between chronological and estimated ages was $-2.1{\pm}6.8$ months for boys and $6.1{\pm}6.2$ months for girls. Therefore, it seems to be more accurate and easier than the earlier methods.

Purpose: The aim of this study was to describe the clinical and biochemical features as well as the molecular analysis of a newly diagnosed illustrative case with ML II and to analyze the clinical features of 11 Korean patients with ML II/III. Method: Including a newly diagnosed patient, total 11 patients in 10 families were diagnosed as ML II (n=7) or ML III (n=4) were enrolled in the study. A diagnosis of ML II or III was made by demonstrating increased lysosomal enzyme activities in the plasma and sequence analysis of GNPTAB with characteristic clinical features. Result: A illustrative case of ML II patient was a 17 month-old boy showing characteristic facial appearance, multiple joint contractures with cardiac involvements. The enzyme assay showed increased lysosomal enzyme activities in the plasma. We identified compound heterozygous mutations in GNPTAB sequence analysis, including a frameshift (c.3428dupA [pAsn1143Lysfs*3]) and a nonsense variant c.673C>T (p.Gln225*). In total 11 patients with ML II/III, the patients with ML II showed severe growth retardation (height standard deviation score -3.2 [${\pm}1.5$]), compare to patients with ML III. Furthermore, patients with ML II patients had serious cardiac problem (n=4), hepatomegaly (n=3) and underwent tracheostomy (n=3) with further respiratory support due to respiratory distress. To improve osteoporosis and bone pain, all patients with ML III and four of 7 patients with ML II treated with intravenous pamidronate. Conclusion: Here we showed a newly diagnosed case of ML II and clinical features of 11 Korean patients with ML II or III. These data could be helpful for further diagnosis of mucolipidosis, a rare inherited metabolic disease, in Korea.
