The purpose of this study was to establish regression equations and probability charts for predicting the sum of mesiodistal crown diameters of unerupted unilateral canine and premolars from the sum of mesiodistal crown diameters of four mandibular incisors in Korean male and female. The plaster casts of 162 children(75 boys and 87 girls) among the contestees in 1994-2001 Healthy Dentition Contest in Seoul were measured. Sex differences are compared and the following results were obtained: 1. Bilateral comparison of sum of widths of permanent canine and premolars showed no significant differences for either sex(p>0.05). Sum of widths of permanent canine and premolars of male were significantly larger than that of female(p<0.01). 2. Regression equations for the prediction of sum of widths of permanent canine and premolars in each sex were as follows Male ${\Sigma}Maxillary$ 345 y= 10.45+0.53x Male ${\Sigma}Mandibular$ 345 : y= 10.07+0.51x Female ${\Sigma}Maxillary$ 345 : y=12.65+0.42x Female ${\Sigma}Mandibular$ 345 : y=11.70+0.42x Male+female ${\Sigma}Maxillary$ 345 y=11.01+0.50x Male+female ${\Sigma}Mandibular$ 345 : y=9.87+0.51x

Purpose: To determine whether the morphological features of the palatal rugae are associated with sex and age in children and adolescents. Methods: A total of 300 diagnostic models of the palatal rugae of children and adolescents were collected. The models were classified into male and female and<13- and ≥13-year-old groups. The palatal rugae pattern, and the number and length of palatal rugae plicae, were analyzed. Results: The number of palatal rugae plicae was higher in females than in males, however, the difference was negligible. In the group aged 13 years or more, the number was higher in the male group on the left side. There was no association between the number of palatal rugae plicae and age group. The type I pattern was the most common in both males and females. The length of palatal rugae plicae was greater in males than in females. There was no association between the length of palatal rugae plicae and age group. Conclusions: The number and length of palatal rugae were associated with sex, but the morphological features of the palatal rugae could not distinguish between children and adolescents. These findings suggest that the palatal rugae have limited value for identification of individuals.

Objective: The purpose of this study were to examine the growth pattern of weak children by measurement according to the five weak symptoms (respiratory, digestive, psycho-neurological, neuromotor, urogenital symptom). Five weak symptoms are common etiology of short stature in childhood and oriental medicine therapy is used as a treatment in short stature but the effects on height are not conclusive. Methods: This clinical study had been carried out with the 166 case (male 74, female 92) of the children aged 3 to 18 years old who visited in growth clinic of Pediatrics, Dongguk university Bundang Oriental Hospital. They were divided into 3 groups by age (3-10, 11-14, 15-18 years group) Five weak symptoms were studied to determine the association with growth stature among children by comparison with the growth stature of weak children group and normal group Results: The distribution of age showed the highest in 11-14 years(58.4%), followed by I 3-10 years (26.5%), over 15years(15%) in order. In case of male, the distribution of five weak symptoms showed the highest respiratory weak symptom(68.9%), followed by digestive(52.7%), psycho-neurological(43.2%), neuromotor(24.3%), urogenital weak symptom (143.5%) and digestive weak children's Height SDS were lower than normal children in all age groups and respiratory weak children's Height SDS were lower than normal children in age group of 3-10. In case of female, the distribution of five weak symptoms showed the highest digestive weak symptom(59.8%), followed by respiratory(52.5%), psycho-neurological(51.5%), neuromotor (35.9%), urogenital weak symptom (25%) and digestive weak children's Height SDS were lower than normal children in age group of 3-14. Other weak children Height SDS were no significant difference from normal group. Conclusions: From the above result, it was suggested that weak symptoms is cause in short stature. These data indicate that the height was correlated with respiratory, digestive weak symptom and a way to improve the weakness increased significantly height in children growth stature. Growth stature should be investigated as a new field of oriental medical treatment and more controlled, long term studies are required to classify benefits of Oriental medicine therapy in short stature.

The purpose of this study was to investigate the effects of obesity on the satisfaction with school lunches and school lunch leftovers of elementary school children in the Kyeonggi area. The study was carried out on 235 children(male : 111, female :124) in December of 2000. The results are summarized as follows. A Rohrer index was used to define obesity. The proportions of severe underweight, underweight, normal, overweight, and obese were 0.9%, 16.6%, 57.9%,17.0%, and 7.7% respectively. For the data analysis, the subjects were divided into 3 groups : an underweight group(Rohrer index 109 including severe underweight), a normal group(Rohrer index 110-140), and an obese group(Rohrer index 141 including overweight). With regard to the satisfaction with school lunches, the proportions of children who were satisfied, neutral, and unsatisfied were 27.2%, 59.6% and 13.2% respectively. The proportion of the satisfaction with school lunches was significantly higher in the male group than in the female group(p〈0.05), and the proportion of the dissatisfaction with school lunches was significantly increased with obesity index(p〈0.05). The largest proportion of children who were satisfied with school lunches answered they felt hungry(56.3%) and the food tasted good(42.2%). Children sho were not satisfied with school lunches answered that the food was not tasty(93.5%), they did not have ant appetite(9.7%), and others. The children not finishing school lunches(leftovers) occasionally or always were 47.7% of the subjects. The behavior of leaving lunch foods was not significantly related to the gender or the frequency of eating snacks, wile it was positively related with dissatisfaction with school lunches(p〈0.01), obesity index(p〈0.05), and the decreased frequency of eating meals per day(p〈0.01). The reasons of school lunch leftovers were food dislikes(67.9%), excess of quantity(39.3%), tastelessness(31.3%), poor appetite(13.4%), and other. The children eating meals twice, 3 times, and 4 times per day were 18.7%, 74.9%, and 6.4% of the subjects respectively. The proportions of the obese and the satisfaction with school lunches were not changed significantly according to the frequency of eating meals, while the proportion of children leaving school lunches was significantly higher in the group of eating meals twice per day than in the other groups(p〈0.01). The frequency of eating snacks was not related to the obesity index, the proportion of school lunch leftovers, or the frequency of eating meals, while the proportion of satisfaction with school lunches was significantly higher in the group of eating snacks 1-2 times per day than in the other groups(p〈0.01). In conclusion, it is necessary to have children enjoy school lunches with efforts to improve the food´s taste in the school food services and to reexamine the serving sizes for the children, in addition to the nutrition education for the children to eat a variety of foods.
