  • The purpose of this study was to investigate the anthropometric and blood biochemical characteristics, the dietary behaviors and health-related lifestyles of obese children in Incheon. A cross-sectional survey was conducted using anthropometric measurements, biochemical assessments and questionnaire analysis. The subjects included 7,055 obese children residing in the Incheon area (from 106 elementary schools). The degree of obesity was classified using the Obesity Index (OI) as light 20% < OI < 30% ; Medium 30% < OI < 50% ; Severe 50% > OI. The statistical analysis was conducted using SPSS 10.0 program. Most subjects fell within the medium range of obesity. Most subjects had dietary problems such as overeating, unbalanced meals and skipping breakfast. The ratio of boy subjects eating green and yellow vegetables was lowe. when compared to that of the girl subjects. The boy subjects exercised more frequently and longer than the girls. As the Obesity Index increased, hypercholesterolemia significantly increased. The blood cholesterol levels of the subjects were positively correlated with body fat, waist/hip ratio and BMI; HDL cholesterol levels of the subjects were negatively correlated with the anthropometric data and the LDL cholesterol levels of the subjects were positively correlated with body fat. The blood triglycerides levels of the subjects were positively correlated with body weight, body fat, waist/hip ratio and BMI. Therefore, proper nutritional education and intervention are required for an improvement of obese children's dietary behavior, heath-related factors and blood lipid profiles.

  • In plastic surgery, patient photography is a vital component of clinical, educational, legal, and research documentation. Optimal acquisition of photographic data requires a dedicated photography studio or a three-dimensional anatomic scanner, both of which are financially impractical for most clinicians. Simplified photo standardization is proposed for use in random clinical settings by using a portable device called the Mirror Stand (MirS). This model device aims to mimic a studio environment by incorporating the basic elements of producing consistent photographs. The pilot MirS is designed for facial photography. Images of 40 random subjects were obtained using the MirS with three different cameras. Real anthropometric measurements of each subject were collected, compared with the photographic measurements, and analyzed. In this study, all three cameras produced equally reliable measurements. Actual facial measurements were comparable to the photogrammetric measurements obtained from photographs taken using the MirS. A constant formula was derived; it allowed the conversion of photographic values into real anthropometric values. The MirS produced consistent photographs with respect to the measurements. The photographs obtained could be translated reliably into their real anthropometric measurements. Therefore, the MirS can be applied in daily practice, providing an efficient alternative for obtaining a standard justifiable photograph.

  • The purpose of this study was to classify female students' somatotypes, to investigate the relationship between five somatotypes obtained from anthropometric measurements and to examine the relationship between the spinal deformity and somatotypes. The subjects for anthropometric measurements were 844 female middle and high school students. The data were analyzed by cluster analysis, correspondence analysis, Duncan test, and T-test. The results were as follows. Cluster analysis on the factors extracted from directly measured items classified subjects into five types (middle height and a little slim type (39.6%), low height and a little slim type (13.1%), middle height and a little fat type (18.0%), tall and very fat type (7.7%), and very tall and standard type (21.6%). In examining the relationship between the normal people and those of the spinal deformity, the normal showed higher mean value in almost all the items of the girth, the depth, and the length. High school students had more spinal deformity in number than middle school students. The degree of deformity was higher in the right spinal deformity than in the left spinal deformity as the age increased. In terms of the distribution of the spinal deformity classified by the somatotype, Type 1 (middle height and a little slim type) and Type 5 (very tall and standard type) appeared the highest.

  • This paper proposes a new personalized HRTF estimation method which is based on a deep neural network (DNN) model and improved elevation reproduction using a notch filter. In the previous study, a DNN model was proposed that estimates the magnitude of HRTF by using anthropometric measurements [1]. However, since this method uses zero-phase without estimating the phase, it causes the internalization (i.e., the inside-the-head localization) of sound when listening the spatial sound. We devise a method to estimate both the magnitude and phase of HRTF based on the DNN model. Personalized HRIR was estimated using the anthropometric measurements including detailed data of the head, torso, shoulders and ears as inputs for the DNN model. After that, the estimated HRIR was filtered with an appropriate notch filter to improve elevation reproduction. In order to evaluate the performance, both of the objective and subjective evaluations are conducted. For the objective evaluation, the root mean square error (RMSE) and the log spectral distance (LSD) between the reference HRTF and the estimated HRTF are measured. For subjective evaluation, the MUSHRA test and preference test are conducted. As a result, the proposed method can make listeners experience more immersive audio than the previous methods.

  • This study analyzed differences between three-dimensional (3D) body scanning and manual measurements, aiming to assess whether 3D scanning can replace traditional anthropometric tools, such as tape measures and calipers. Data from 4,478 participants in the 8th Size Korea Project were analyzed, covering 43 measurement items. Since Given that the 3D and manual measurements were performed on the same subjects in the 8th Size Korea Project, it was possible to determine the correlation more accurately between the two measurement methods more accurately. Using Applying ISO 20685-1(2018) standards, 15 out of the 43 items fell within allowable error limits. When classified into six types, "small circumferences" and "segment lengths" showed averages of 3.35 mm and 3.10 mm, respectively, within acceptable range. "Body heights" and "body depths" slightly exceeded the limit, with averages of 5.28 mm and 6.58 mm. "Body widths" and "large circumferences" surpassed the limit, with means of 16.77 mm and 16.18 mm. The study offers an objective basis to for validate validating 3D measurements' measurements' reliability and accuracy, addressing various industries' needs for information on the human body's dimensions information.

  • Objectives: No 3D anthropometric analyses have been conducted for Korean children's faces for the purpose of designing respiratory protective devices. The aim of this study was to develop masks against yellow dust and fine particulates, particularly for children in Korea. Methods: This study utilized a 3D scanning method to obtain 16 facial anthropometric data from children, ages of 5 to 13 years old. A total of 144 boys and girls were recruited from the kindergarten, elementary schools and middle schools in Seoul. With facial dimensions obtained, cluster analysis was performed to categorize them into similar facial groups. For each cluster, an optimal mask was designed and manufactured using a 3D printer. In addition, lung function data were obtained from 62 subjects and compared with those of normal adults. The pulmonary physiological results were subsequently used to suggest a test method for mask certification. Results: Facial shapes were classified into tree clusters: small, medium, and large. The face width and length for the first group were small with high nosal protrusion. The face width and length for the second group were the largest among the three clusters. The third group had the largest angle of nose root - gnathion(n-prn-gn). Age was the most significant variable in the facial dimensions. Children's pulmonary physiological capacity was about 60% of adults' capacity. The results of fit test using the prototype masks developed showed very good fits for children. Conclusions: For Korean children, three mask sizes will be sufficient and practical for providing protection against yellow dust and fine particulates. Anthropometric data obtained using digitalized 3D face analysis can be very effective for designing respiratory devices. 3D images can be accurate and easily measured for multiple dimensions, particularly for curved areas of the face. It is imperative to adopt different test methods for certifying respiratory protective devices for children, since their pulmonary physiological capacity is inferior compared with that of adults.

  • This study was performed to investigate the anthropometric data, serum profiles, and nutrient intakes of high school students who are living in Seoul. Anthropometric data showed that mean height and weight were 174.1 cm and 66.6 kg in 99 male and 161.4 cm and 54.0 kg in 116 female students. Mean BMl for male and female students were 21.9 and 22.3 kg/$m^2$, and subjects with BMI > 25 kg/$m^2$ were 14 and 7%, respectively. Total cholesterol, HDL- and LDL-cholesterol of subjects were 149.6$\pm 3.1,\; 46.4 \pm 1.3,\; 86.4 \pm 2.3$,/TEX> mg/dl for males and 169.2 $\pm 3.1,\;50.7 \pm 1.0,\; 100.9 \pm 2.7 mg/dl$ for females, respectively. Hemoglobin (Hb) and total iron binding capacity (TIBC) were 12.8 $\pm 0.1 g/dl, \;437.3 \pm 7.2\mug/dl\; in\; male\; and\; 11.9 \pm 0.1 g/dl,\; 439.4 \pm 5.7\mug/dl$ in female, respectively. Based on Hb classification, 45.6% of male and 45.0% of female students fell into anemic condition. Intakes of energy, Ca, Fe, Zn, riboflavin, and folate were below the Korean RDA. In particular Ca (male and female, respectively, 64.6 and 64.3% RDA) and Fe (male and female, respectively, 78.6 and 64.3% RDA) intakes were extremely low. Serum triglyceride was positively significantly correlated with weight (r =0.22), BMI (r =0.279), waist circumference (WC, r =0.235), triceps skin-fold thickness (TSF, r =0.197) and obesity index (OI, r =0.279). Hb concentration was positively correlated with height (r + 0.387), weight (r =0.349), BMI (r =0.191) and waistlhip ratio (WHR, r =0.380). As for the correlation between serum profiles and nutrient intakes, the Hb concentration was positively correlated with energy (r =0.163), protein (r =0.149), Na (r =0.153), vitamin A (r =0.165), thiamin (r =0.201) and niacin (r =0.192, p < 0.01). These result suggest that the prevalence of Ca and Fe deficiency of student is high and dietary guideline for prevent anemia in this age needs to contain the adequate intake of energy and its related vitamins.

  • Purpose: The purpose of the study was to examine whether anthropometric estimations can be reliable methods to assess body fat of university students, by identifying the relationship between anthropometric estimates, which have been thought to be not reliable but economic, and Bio-electric impedance analysis (BIA), which has been known to be reliable but expensive. Method: Twenty-one male and 20 female university students were recruited. The in Body 3.0 scale and GIF-891DX were used for BIA. Body fat was estimated with 12 circumferences, 9 skin-fold thicknesses (SFT), and applying 4 equations (Kim's, $Broz{\check{e}}k's$, Siri's and Wilmore's). Their relationships were examined by Pearson Correlation. Result: 11 circumferences and 9 SFT in the male while 5 circumferences and 3 SFT in the female correlated with the body fat on BIA(p<05). The waist circumference had the strongest correlation to the BIA in both males and females. The abdomonial SFT for the male and scapular SFT for the female had the strongest relationship of SFT to BIA. Body fat estimated from more than two different equations significantly correlated with those measured from BIA (p<.05). Conclusion: Anthropometric estimations could be a useful method to get reliable and valid data for body fat of the university students inexpensively.
