The purpose of this study was to identify the body shape satisfaction and body shape esteem according to the state of obesity in elementary school students. The data were collected from May 1st to 31th, 1999 using the questionnaire and the physical examination record. The subjects were 669 in 12-year old children. Data were analyzed with frequency, percentages, crosstabs, ANOVA, pearson correlation using the SPSS program. The results were as follows: 1. The prevalence of overweight was 14.0% of total students, 21.4% of mail students and 6.6 % of female students. 2. There were significant differences in the body shape satisfaction according to the state of obesity in total students(($chi^2$ = 110.31, p = .000), in mail students(($chi^2$ = 99.97, p = .000), in female students(($chi^2$ = 62.23, p = .000). The percentages of the body shape satisfaction were highest the underweight group in total and female students but in mail students the normal weight group was highest 3. There were significant differences in the body shape esteem according to the state of obesity in total students(F = 8.634, p = .000), in mail students(F = 11.738, p = .000), in female students(F = 4.502, p = .004). The mean scores of body shape esteem were highest the normal weight group in total students, overweight group in mail students and underweight group in female students. The higher the state of obesity was, the lower body shape esteem. 4. The relationships between body shape satisfaction, body shape esteem and obesity index were significant. Obesity index were significantly and negatively related to body shape satisfaction(r = -.2081, P = .000), to body shape esteem(r = -.2250, p = .000). 5. There were significant differences in the state of obesity according to sex(($chi^2$ = 88.136, p = .000) and the perception of body shape(($chi^2$ = 242.371, p = .000) in total students. There were significant differences in the state of obesity according to the body shape of father(($chi^2$ = 15.11, p = .019), the perception of body shape(($chi^2$ = 138.95, p = .000) in mail students. There were significant differences in the state of obesity according to the education of mother(($chi^2$ = 19.46, p = .022), the perception of body shape(($chi^2$ = 143.35, p = .000) in female students.

During tooth formation, tooth development can be affected by physical action or metabolic changes around dental follicle. Especially trauma to primary dentition is the most representative physical factor that can cause development disorders of succedaneous tooth. Enamel hypoplasia and crown discoloration of succedaneous tooth are common complications of trauma. And impaction, ectopic eruption, arrest of root formation and root dilaceration of succedaneous tooth are rare. In this case, a 6-year and 5-month-old female patient visited for dental evaluation after trauma. She was diagnosed with alveolar bone fracture near upper front teeth, extrusion of the upper right and left primary central incisors, intrusion of the upper right primary lateral incisor, and palatal luxation of the upper left primary lateral incisor. Upper right and left primary central incisors with severe mobility were extracted, with gingival suture on the day of the visit. During 24 months check up, root dilacerations were found near the cemento enamel junction in the upper lateral incisors and arrests of root formation were found on the coronal 1/3 of the root in the upper central incisors. Although alveolar bone fracture is rare type of trauma in children, a thorough examination of alveolar bone is essential for prognosis and following treatment in patients with trauma.

Background : Since 2001 the Korean Association of Health Promotion has attempted to establish her own reference valves that can be used in her all fifteen branch laboratories instead of using those adapted from the published data or there commended data by the reagent companies supplied as inserts. However, the previous two reference values derived from the statistics(year 2001 and 2002) were need to adjust to apply to actual practice. Besides there was an unavoidable situation that the reagent has to be changed to other companies in 2002 that creates another statistical problem. Subsequently, the third attempt to derive the reference ranges of tests in KAHP to solve those problems and define common)v acceptable reference ranges was done and and reported here. Methods : Al1 the results performed during January 2, 2003 through September 30, 2003 were collected in Excel tile format. All the data include dthe necessary information such as age and sex. The age was grouped in six; baby(0-3y), children(4-l2y), adolescent(13-l8y), adult(19-S4y), younger elderly (65-79y),old elderly(oyer 80y), with references of statistics in medical informatics and WHO classification. The data were statistically analyzed with SAS 6.04 for-Gaussian distribution as the previous two occasions. None of the tests showed Gaussian distribution. These procedures had been repeated twice or three times after trimming out the results lying outside three standard deviations. Though, all the tests showed non-Gaussian distribution. Subsequently, the reference ranges were defined in the range from the point of lower 2.5% to the point of higher 97.5 %. And in case the lower range could be "0", the reference ranges were defined in the range of 0 to 95%.Results : The reference ranges of most of 56 test items were newly assigned. Also with adaptation of the recommendation of WHO etc. on fasting blood sugar, hemoglobin, cholesterol. Among these there were eight tests that needed reference ranges by the age groups and nine tests by the sex. Conclusions : The third attempt will credit more the reference range of all15 laboratories of Korean Association of Health Promotion, which will be essential part of the better service to the patient and clients to visit KAHP.

Osteosarcoma in patients older than 40 years are rare, however they have different clinical, radiological and pathological features from those of younger patients. Sometimes accurate histologic diagnosis is not easy, which is important in determining the correct surgical treatment and appropriate chemotherapy. Since January 1995, 11 patients with osteosarcoma occurring in patients older than 40 years have been diagnosed, treated and followed up for more than 6 months. In contrast to osteosarcoma in children and adolescents, only 4 cases(36.4%) were conventional types, while the others included 2 malignant fibrous histiocytoma-like types, 2 small cell types, 2 periosteal osteosarcomas and 1 giant cell-rich type. Seven cases showed purely osteolytic or predominantly osteolytic bony lesions and 8 were in Enneking stage IIB. Performed surgical treatments included 2 amputations, 6 wide resections and reconstructions, and one curettage and autogenous bone graft. In the remaining 2 cases, definitive surgical treatments included not carried out because of old age, multifocal involvement or poor medical tolerance. Neoadjuvant and adjuvant chemotherapies were performed in 9 of 11 patients. At last follow-up, there were 6 continuously disease-free survivals, 3 alive with diseases and 2 died of diseases. The overall cumulative 4-year survival rate calculated using Kaplan-Meier's productlimit method was 59.3%. For improved oncologic outcomes and survivals, early and accurate diagnosis, surgical treatment with adequate margin and neoadjuvant and adjuvant chemotherapy will be necessary.

1. As the low standard of living of the people who live in both the model and compared villages, is almose similar to each other, the state of their food intaking has nearly the same degree. 2. The villagers of the two kinds of village mentioned above do not cast off their traditional eating habits getting an energy from rice and vegetarian diet. They, however, have been so much interested in the problem of birth control that they have a few children in less than four-year-old. We have to go on the problems of driving a reasonable family plan, and replacing the traditional food life by taking a fatty food. 3. Their pool life forces them to have an over work for supporting their family. Even though they take much Fe from grains and vegetables day after day, Fe does not give a great influence on making Hb (Erythrocyte) in a body. Accordingly most of them have developed symptoms of anemia. This research, comparing with the research results of Ewha University and Seoul Medical College shows much lack of Hb. So it is need for them to take a large quantity of animal protain and make a healthful habit by reforming their food life.

Deep caries in primary molars without early intervention frequently induce a pulpal disease and consequent furcation lesion with fistulous openings Up to now, majority of the textbooks on pediatric dentistry and literatures have described that extraction of the inflicted teeth is indicated for these cases and in reality these teeth have usually been extracted in the dental clinics. However when we recognize the excellent capacity of bone regeneration in children and the presence of numerous accessory canals at furcation areas, the removal of infection source in pulp by pulpectomy and inflammatory granulation tissues at furcation areas by furcal curettage might open the possibility of rapid healing at the furcation regions. In this report, 10 cases of primary molars in 3 to 6-year-old children with fistulous openings and furcation lesions in moderate size of 2 to 4mm in depth radiolucency at furcation lesion have been chosen. After pulpectomy and furcal curettage, evident bone regeneration was detected radiographically in all cases. Through the cases, we came to realize that all the cases previously described are not the indications of extraction and this approach could make many cases with pulp and furca combined lesions survive and remain healthy in the children's dental arches. However, in order for this approach to acquire objective appropriateness, it is thought that more scrupulous evaluation is desirable on the various factors regarding the indication such as the extent of furcation lesions, absorption status of teeth, amount of covering bone on succeeding teeth and so on.

Lennox-Gastaut syndrome (LGS) is a severe form of childhood epilepsy that is defined by generalized multiple type seizures, slowness of intellectual growth, and a specific EEG disturbance. Children affected might previously have infantile spasms or underlying brain disorder but etiology can be idiopathic. LGS seizures are often treatment resistant and the long term prognosis is poor. A 14-year-3-month old, 20.5 kg girl with LGS was scheduled for dental treatment under general anesthesia. The patient presented with multiple caries and heavy calculus. General anesthesia was induced and maintained with inhalation agent, Sevoflurane. And caries treatment, scaling, subgingival curretage were performed. LGS patients usually have poor oral hygiene due to mental retardation and have high risk of seizure during dental treatment. In dental treatment under general anesthesia for LGS, it must be considered of seizure control during peri-operative period. Also periodic recall check, instruction of oral hygiene must be performed.

Although adolescents usually show peculiar aspects in oral health status, there have been not so many studies about it, while there have been innumerable studies for children. This study aimed at evaluating the prevalence of dental caries of adolescents in Yangsan in Republic of Korea, detecting its contributing factors, and distinguishing the high-risk group by epidemiological mass survey. Besides, the significance including early caries lesion in diagnosis criteria was assessed with minimal invasive concept. This survey was performed on 1,371 adolescents aged 14 to 16 in Yangsan as subject examinees by a single trained examiner. The dental caries status was checked by oral examination at schools and questionnaire survey was accompanied for some relevant risk factors. The data were analyzed to yield the results as follows: Regarding the caries experience, the DMFT score by WHO criteria with ECL including or not was 4.79 and 3.97 respectively. In both the criteria, female showed higher values and that of high-risk group was almost twice compared with whole examinees by Sic Index. About pit & fissure sealed rate, it revealed the tendency that the more sealed teeth, the lower DMFT values. Among the studied risk factors, only the habit of brushing before going to bed showed positive relationship (p < 0.05).

Objectives : During March-May, 2000, a measles outbreak occurred at Youngduk, Korea. This county is divided into two areas with different historical and socioeconomic background. The outbreak occurred in one of these areas. We conducted a comparative epidemiologic study on the two areas in order to evaluate the factors related to the epidemic. Materials and Methods : We selected two groups, grades 3 and 5 in a primary schools in each area. We investigated outbreak-related factors using parent-questionnaires, the vaccination history from the student's health record and the records concerning the recent measles-outbreak from the local health center. Serologic test on measles-IgG and -IgM antibody was done. Results : The infection rate was 31.5% for the epidemic area and 3.7% for non-the epidemic area according to clinical or serological criteria (p<0.001). No difference was seen in the measles vaccination rate, residence at the time of vaccination or past measles infection history between the two areas. In the epidemic area, the attack rate for the 4-6 year-old MMR booster group(20.5%) was higher than the non-booster group(32.4%), but was not found significantly. Vaccine efficacy was 29.6% in the epidemic area and 87.0% in the non-epidemic area (p<0.001). The IgG level and positive rate were significantly different between the two areas (median 10727 IU/ml, 98.9% in epidemic area; median 346 IU/ml, 85.9% in the non-epidemic area, p<0.001). However, the IgG level and positive rate between the measles-cases and non-cases were not significantly different. Conclusions : This outbreak took place in mostly vaccinated children. These results suggest that a reduction of herd immunity for immunity failure after vaccination may be one of the feasible factors related to the outbreak pattern in the two areas. The results of the IgG level and positive rate suggest that re-establishment of a normal value for IgG level and of a qualitative method for IgG are needed.

This study is an attempt to give basic information for sex maleducation, which is the integration of emotional, moral and social aspects as well as generative and physiological ones. It is concerned with both students and parents' sexual knowledge, attitude and need for sex education. The participants for this study are consisted of 193 parents, and 492 boys and girls high school students in Seoul. The main results of this study are as follows: 1. General Characteristics 66.5 percent of students is the girl and 38.8 percent of students is christian. Regarding parents age, 73.6 percent of them is 40~49 year old and 30.6 percent of them is Buddhist. 50.5 percent of them is graduated from high school, almost of them are keeping on being married(90.9%). 2. Sexual Knowledge: The boys score higher grade(average 8.98) than the girls. (average 7.51) (p<0.001) The Parents appear to record average 11.5, higher than the students' 8.01(p<0.01). However, there is no difference between them depending on their age, educational level or marital condition. 3. Sexual Attitude: The boys have more affirmative and positive feelings on the generative and physiological sides than girls. They also have a positive attitude to usual sides such as marriage, sexual intercourse and pregnancy, compared with girls. The girls have negative and irrecipient attitude to unusual sides like divorce, premarital sex or extramarital sex, while the boys are recipient(p<0.01). The parents' sexual attitude is positive feelings on the generative and physiological sides, and they also have a positive attitude to usual sides but they have a negative attitude to unusual sides. 4. Correlation between sexual knowledge and attitude Both the students and parents have positive correlation between sexual knowledge and attitude to generative and physiological sines and usual sides. The higher scores. of the sexual knowledge are, The more positive attitude they have. But parents only have positive carrelation between sexual knowledge and attitude to unusual sides. The lower scores of the sexual knowledge are, The more negative attitude they have. 5. More than half of the parents educate their high school children in sex: menstruation(75.0%), sexual hygiene (59.1%). intersexual fellowship(69.7%). marriage(62.0%) and chastity(51.9%) 6. Need for sexual education The students and the parents have almost the same opinions on this subject. Regarding pregnancy. delivery, family planning, dilatation and currettage and divorce, however, the students want to learn in high school. while the parents expect sex education later in high school.
