  • An alternative way of constructing ancestral graphs, which is different from the coalescent-based approach, is proposed using population linkage disequilibrium (LD) data. The main difference from the existing method is the construction of the ancestral graphs based on variants instead of individual sequences. Therefore, the key of the proposed method is to use the order of allele ages in the graphs. Distinct from the previous age-estimation methods, allele ages are estimated from full haplotype information by examining the number of generations from the initial complete LD to the current decayed state for each two variants depending on the direction of LD decay between variants. Using a simple algorithmic procedure, an ancestral graph can be derived from the expected allele ages and current LD decay status. This method is different in many ways from previous methods, and, with further improvement, it might be a good replacement for the current approaches.

  • This study divided school age by considering a change in the stage of body growth by age in elementary schoolgirls with the use of body scan data, and considered by comparing body size characteristics by school age. Elementary schoolgirls' body shape cannot be divided clearly. However, ages 7-10 were bound into the same group for the majority of girth, width, and thickness items. 7-8 years old, 9-10 years old, and 11-12 years old were bound into the same group in most items except ages 9 and 10 for the height item. Thus, significant difference was indicated between groups. Accordingly, this study divided the school age into three periods such as early stage(ages 7-8), middle stage(ages 9-10), and late stage(ages 11-12) in consideration of the stages for elementary schoolgirls' body-shape growth. As a result of analyzing body size according to division of school age, the higher school age leads to continuous growth. The notable growth was indicated especially in the middle stage and late stage. Examining centering on typical items related to the clothing construction, there was notable increase in waist thickness and hip thickness between early and middle stages and in height, weight, breast girth, waist circumference, back length, breast width, and waist width between middle and late stages. On the other hand, hip circumference, hip width, breast thickness, and length between shoulder edges were indicated to grow relatively and evenly among early, middle, and late stages. The lateral form was shown a clear difference in the forms of early, middle, and late stages in height and length of the whole body shape and in side thickness. The early and middle stages belong to body shape that abdomen is projected to be curved. The late stage showed right body shape which is straight and stable form in posture.

  • This study investigated the determination of speech rates, words per minute (WPM) and syllables per minute (SPM), of $5{\sim}7$ year-old normal children to understand if there are any differences in the rates according to the children's age and sex. All participants were required to conduct story retelling tasks (SRT) and picture description tasks (PDT). In SRT, there was a significant difference between the groups of 5 year-old and 7 year-old children on WPM. However, there was no significant difference between the groups of ages regarding SPM. In addition, there was no significant difference between the groups according to sex on WPM and SPM. In PDT, there was no significant difference between the groups according to their ages and sex on WPM and SPM. The current research found that the speech rates of the preschool children might be somewhat different in their utterance abilities according to their age, but there was no obvious difference according to their sex. The findings can advance development of a clinical tool to screen children with fluency disorders and to determine the steps in establishing speech rates of children in the language development period.

  • The purpose of this study is to examine the increments of body measurements of the teenage boys between the ages of 13 and 18 and provide a fundamental data for apparel manufacturers in order for them to make clothing that reflect the appropriate body characteristics of the teenage boys. The total of 1587 male subjects between the ages of 13 and 18, from the 5th Anthropometric survey of Korea (Size Korea) data, were used for this study. The changes in the body dimensions were analyzed with anthropometric measurements and anthropometric index mesurements. First, anthropometric measurement results show that most of the height related measurements increased in accordance with age, and that the boys between the ages of 13 and 15 experience dramatic growth. Standard deviation is the largest between the age of thirteen and fourteen which indicates that in these ages there is a wide difference in a growth rate Second, anthropometric index measurement results show that in accordance with age, bust, waist and hip depth/width rate decreased; however, waist and hip depth/width rate increased at the age of 18. In accordance with age, upper body length rate increased, whereas lower body length rate decreased. Bust circumference, armhole length, and upperarm circumference rate increased gradually, whereas waist circumference decreased.

  • This study was designed to analyze the results of stress index by heart rate variability test. The subjects were workers in the automobile manufacturing industry. The subjects consisted of 23,767 workers who had answered about questionnaires of a job position, age, smoking, drinking, exercise state and sex. The stress index(SI) and stress resistance(SR) were examined by SA3000P. We analyzed the differences of SI and SR according to job positions, ages, the state of smoking, drinking, exercise and sex by T-test or ANOVA with SPSS ver. 17.0. Regarding the differences of SI among job positions, the SI was highest in sales positions. Among ages, the SI was highest in 30s. In smoking, the SI was lower in non-smoking group. In drinking, there was no significant differences in SI. In exercise, the SI was lower in exercise group. In sex, there was no significant difference. The case of SR, SR was lowest in sales positions. Among ages, the SR was lowest in 40s. In smoking, the SR was lower in smoking group. In drinking, there was no significant differences in SR. In exercise, there was no significant difference. In sex, the SR was lowest in male. According to these results, we should establish the methods of controlling stress from the perspective of Korean traditional medicine.
