In prolonged chronic osteomyelitis, chronic inflammation and low-grade infections can result in new periosteal bone formation. Chronic osteomyelitis with proliferative periostitis (traditionally termed $Garr{\acute{e}^{\prime}s$ sclerosing osteomyelitis) mainly affects children and young adults. Here, we present two rare cases of an 11-year-old and a 12-year-old patient with suppurative chronic osteomyelitis with proliferative periostitis without any definitive infection source, such as dental caries or periodontitis. The source of infection was likely to be related to the development of a lower right third molar germ with follicular space widening. Management involved antibiotics and the removal of the third molar germ and surgical debridement. Disease remission and a normal appearance was observed at the six-month follow-up visit.

Creatinine is a general marker as a screening test for renal disease. This study was conducted to provide basic data about pediatric concentration for serum and urine creatinine. The data from the 2011 Korean National Health and Nutrition Examination Survey was used. Analysis was done on 488 Children and Adolescents (boys 278, girls 210) aged 10 to 19, the Jaffe reaction method was used to gather the data. The highest serum creatinine levels were found in boys aged 19 to 20 years, the mean being 0.97 mg/dL (min 0.81 mg/dL, max 1.14 mg/dL). The levels showed increase over those in the 10 year old group. The highest urine creatinine levels were found aged 19 to 20 years, and the mean was 222.68 mg/dL (min 133 mg/dL, max 324 mg/dL). In the case of girls, the highest serum creatinine levels were found with those aged between 18 and 19, the mean being 0.71 mg/dL (min 0.49 mg/dL, max 0.84 mg/dL). The levels showed increase over the 11 to 18 year old group. The highest urine creatinine levels were found aged 14 to 15 years, and the mean was 218.44 mg/dL (min 131 mg/dL, max 321 mg/dL). The mean difference in serum creatinine in all age groups was statistically significant except for those aged 10 to 14, that of urine creatinine in all age groups was not significant statistically except for those aged 12 to 13, 17 to 18. Therefore, it is suggested that reference values for children and adolescents should be divided into different groups according to gender, further studies are needed using complementing data of the pediatrics.

This study is aimed at exploring a reasonable and reliable method of measuring pre-school children's somatotypes and there by, data basing the information obtained and classifying their somatotypes, at providing useful data which can be utilized for the design of their dress forms and enhancing the fitness of their apparels. to this end, 330 pre-school children living in the capital area and aged fro m4 to 6 were sampled to be subject to the measurement of their somatotypes. The results of this study can be summarized as follows; 1. As the pre-school children grow, the scales indicating their vertical growth including height could well be measured differently, but those scales indicating their lateral somatotypes which reflect their postural changes did not show among age groups. in other words, male kids were higher in the scales including height than female kids, while there were not differences between sexes in most scales indicating their lateral somatotypes. 2. The elements comprising the somatotypes were the size of body skeleton, the thickness of body mass, the posture and shape of body mass, the lateral under-neck shape, the extrusion of belly, the length between front and the back shoulder, the shape of lower belly, the shape of upper hip, the shape of lower hip and the slope of shoulders. Among them, the first two elements accounted for 64.8% of the total distribution, which means that these two elements explain the body-mass somatotypes of kid's most effectively. 3. The sample kids were divided into two types for classification of their somatotypes. As a result, it was found that the elements determining their somatotypes most influentially are, unlike adults' case the size of body skeleton rather than posture or lateral body shape. The type I showed less dimensions in most scales than type II, while their shoulder were les developed,. The type I was found distributed much in 4-year-old female kids. The type II showing more development in each element was found distributed much in 6-year-old male kids.

The objective of this study was to examine multicultural family children's adjustment process to kindergarten and differences in their adjustment among time points. For these purpose, we conducted interviews and a questionnaire survey with teachers in charge of 3-5-year-old young children from multicultural families at public and private kindergartens in Gwangju, Jeollanamdo and Daejeon. According to the results of this study, multicultural family children adjusted themselves to kindergarten through four weeks' daily life in the kindergarten. In daily work adjustment, they showed some difficulty in Week 2 but their adjustment improved rapidly in Week 3 and Week 4. Self adjustment and peer adjustment also improved notably in Week 3 and Week 4. In pro-social adjustment, the children showed difficulty in Week 2, improvement in Week 3, and again difficulty in Week 4. These results suggest that, by responding to the teacher's sensitivity and intimacy, young children in multicultural families have a pattern of adjustment similar to that of young children in Korea families.

The teacher's role scale for improving young children's creativity is designed for both teacher self-rating and observer rating. Content validity was determined by 5 experts who defined the domains of specific content. Construct validity was obtained by the self-ratings of 404 teachers of 3- to 5-year-old children. Five factors using 38 items of the original 59 were found to be related to the teacher's role in improving young children's creativity. The factors were Indulgence and Perseverance, Flexibility, Originality, Elaboration, and Fluency. Convergent validity was confirmed by positive correlations of the Teacher's Role Scale with the Teacher's Creativity Test of the Korean Institute for Research in the Behavioral Sciences. For internal consistency, Cronbach ${\alpha}$ of the 5 factors ranged from .74 to .88. Test-retest reliability coefficientents ranged from .653 to .838. These results confirm the Scale as a valid and reliable measure of the teacher's role in improving the creativity of young children.

This study developed an experience-based economic education program and examined its effects on young children's economic concepts and purchasing behavior. Subjects were 60 5-year-old kindergarteners assigned to an experimental or a control group. Instruments for pre- and post-tests were the Economic Concept Task (Laney, 1995) and the Purchasing Behavior Task (Jang, 2004). Experimental group children participated in the economic education program for 5 weeks; control group children listened to economic stories. Differences between pre- and post-test in the experimental group showed that the economic education program was effective in development of concepts of scarcity, opportunity cost, resource/production, goods/services, and complements/substitutes. Children's purchasing behavior changed partially after application of the program.
