  • This study aims to suggest basic data for the production of hats for aged women. The subjects were 151 females who are 60 years old or above and live in Busan. Their hat-wearing reality was inquired and their head parts were measured, which led to the following conclusion: 1. Results of Hat-Wearing Reality Inquiry 64.9% answered they are unsatisfied with the size system of the available hats at present, implying the necessity for improving the current dimension system. 92.7% responded hat dimensions need to be subdivided, while 97.4% were for the necessity of hat size system. 74.8% expressed their will to buy ordered hats because they can find the hats of right sizes and designs. 2. Results of Head-Part Measurement Experiments According to head-part measurement, head circumference A was 53.26cm, head circumference B 54.19cm, and head circumference C 57.69cm on the average. Cluster analysis revealed three types. Type 1 (24%) with small head length and circumference is the smallest head with a wide upper part. Type 2 (33%) has long head height, short bitragion arc A, and thick head breadth. Type 3 (43%), owing to big head circumference and length as well as high values in vertical items. Considering head circumference B (HCB) and bitragion arc A (BAA), a new hat size system of 3 sizes (HCB: BAA) was chosen: S (52cm: 29cm), M (53-55cm: 30cm), and L (56-57cm: 31cm).

  • Background: Brain volume is associated with dementia and depression in the elderly. An easy way to predict relative brain volume is to measure head circumference. In this study, we investigated the relationship between head circumference and cognition as well as depression in a non-demented elderly community. Methods: Baseline and follow-up surveys were conducted in 2007 and 2010. At baseline, community residents aged 65 years or over (n=382) within a rural area of South Korea were screened for dementia and symptoms of depression and were followed using the same screening battery after 3 years (n=279). Data from anthropometric measurements (head circumference, height, and body weight), demographics, and blood tests were gathered. Neuropsychological tests, including the Korean version of mini-mental state examination (K-MMSE), clinical dementia rating (CDR) including the CDR-sum of boxes, the Korean version of instrumental activities of daily living, and geriatric depression scale (GDS), were performed. None of the 279 subjects followed were demented. Results: Baseline performance on the K-MMSE and GDS was poorer for participants with smaller head circumferences. Follow-up performance on the MMSE was also poorer for participants with smaller head circumferences. Interestingly, participants with smaller head circumference showed worse GDS scores at baseline but on follow-up examination, participants with larger head circumference showed rapid worsening than those with smaller head circumference with marginal significance by ANOVA test. In regression coefficient analysis, GDS decline showed significant difference. Conclusion: Head circumference was not associated with cognitive change but was associated with symptoms of depression in non-demented community residents.

  • The purpose of this study was to provide some preliminary results on application of 3D scan data of head shapes to the hat design and pattern-making. This paper defined necessary measurement items and concepts in 3-dimensional images of head shapes. And also it presented the methodology to pattern-making of 6-piece crown hat based on 3D data. It used the data of Size Korea to pick up and choose a head shape model with the average head size of Korean women in their twenties. Main results were: 1. The 3D scan data of head shape was better than the 1 dimensional measurement data. Because I could establish a hat pattern-making theory by the 3D scan data of head. 2. The 3D scan data provided the basis for conceptualization of basic measurement points and items for a better fit of hats as well as the definition of the basic hat circumference. 3. This presented a methodology for analyzing out head shape by 3D scan data, and allowed the derivation of the basic hat circumference from the maximum head circumference. 4. As the 6-piece Crown cloche hat made by this method fitted the head shape model perfectly, this methodology could suggest potential applicability to various hat design.

  • The purpose of this study is to provide basic data for the medical nutrition therapy of premature infants. The general characteristics, presence of metabolic disorders, hematological profile and feeding methods were compared between the premature infant group (<37 weeks, n=61) and the full-term infant group (37$\sim$42 weeks, n=165). Birth weight (p<0.0001), birth length (p<0.005), head circumference (p<0.0001), chest circumference (p<0.0001), and Apgar scores (p<0.0001) of the neonates were all statistically lower in the premature infant group. Jaundice cases (p<0.0001) were statistically higher in the premature infant group. White blood cell counts (WBC: p<0.005), mean corpuscular volume (MCV: p<0001), mean corpuscular hemoglobin (MCH: p<0.005), mean corpuscular hemoglobin concentration (MCHC: p<0.005), and mean platelet volume (MPV: p<0.05) were statistically lower in the premature infant group. The premature infant group were fed a higher rate of premature formula than breast milk and the full-term infant group were fed a high rate of human milk at a higher rate, showing differences in kinds of feeding methods (p<0.0001) between the two groups. An infant's birth weight showed a significantly positive correlation with the infant's birth length (p<0.0001), head circumference (p<0.0001), chest circumference (p<0.0001), and Apgar scores(p<0.0001). The birth length also showed a significantly positive correlation with both head circumference (p<0.05) and chest circumference (p<0.05). Head circumference showed a significantly positive correlation with chest circumference (p<0.0001) and Apgar scores (p<0.0001). Chest circumference showed a significantly positive correlation with Apgar scores (p<0.0001). In addition, the Apgar Score at of 1 minute after birth showed a significantly positive correlation with the Apgar score at of 5 minute after birth (p<0.0001).

  • The purpose of this study was to investigate the effect of massage therapy on weight gain, length and head circumference in instituted infants. This study utilized nonequivalent control group with repeated measuring by quasi experimental design. Fifty eight instituted infants in Daejeon city were selected for the study. Fifty eight infants were randomly assigned two groups, one served as the control group and the other was experimental group to whom massage therapy was given. For the experimental group, massage protocol(developed by Field, 1986) was applied 2 times a day, mid-morning and early evening, for 4 weeks for each infants by researcher and trained research assistants. As a weight weighing instrument, electronic indicator scale (Cas Co., Korea) was used. The result of this study were summarized as follows; 1.A repeated measures ANOVA identified a significant group by time effect over the four weeks of intervention(F=14.69, p < .0001). Infants assigned to experimental group gained more weight than control group infants. 2. T-test identified that significant differences in length(t=2.60, P=.013) and head circumference(t=4.27, P=.000). Infants assigned to experimental group had more length and head circumference than control group infants. In conclusion, Massage therapy improved weight gain, length and head circumference of instituted infants. Therefore, it is recommended to utilize massage therapy as a nursing intervention for instituted infants.

  • Background and Objectives: Obesity is one of the most important risk factors for obstructive sleep apnea (OSA). There is limited evidence regarding the obesity-related anthropometric characteristics of Korean patients. Materials and Method: Medical records of 984 patients referred to 3 tertiary referral hospitals for habitual snoring or sleep apnea were analyzed. We defined OSA as apnea-hypopnea index (AHI) ${\geq}5$ and analyzed data to determine the anthropometric characteristics of patients with OSA such as neck circumference (NC), waist circumference (WC), hip circumference (HC), and waist to hip ratio (WHR). Results: A total of 952 patients (719 men) were included in the analysis. The main findings were: 1) BMI, WC, NC, HC, and WHR were greater among patients with OSA than among controls (AHI <5); 2) for both sexes, the proportion of patients with an OSA diagnosis increased with age; it increased steeply for women aged >50 years; 3) WC and WHR were most strongly correlated with AHI for men and women, respectively. Conclusion: OSA is associated with anthropometric characteristics, although different patterns were observed between men and women. OSA was more strongly associated with NC or WC among men and with WHR among women.

  • The purpose of this study was to point out the unification of the size of swimming headgear by measuring detailed measurement of head ferm and systematizes the head form. A total of 300 male and female Korean adults aged from 18 years old to 35 years old were measured through the direct measurement method. This study attempted to identify the head form of male and female adults using measurement data and the head form was classified through factor analysis and cluster analysis. (1) Based on the fact that this study especially focuses on the size of swimming headgear, factor analysis was performed far both direct measurements with hair and without hair. For the measurements with hair, seven factors were extracted. They were head thickness factor, head width factor, width of side head factor, height of back head factor, length of front head factor, circumference of front head factor, thickness of front head factor and head height factor. They explained the $70.95\%$ of the measurements. (2) The cluster analysis was executed to classify the somatotype of the korean head form on the basis of similarity. According to the cluster analysis result, the measurements with hair categorized types, 'Woman's long-hair type', 'Small type', 'Long and flat type', 'Large type'. (3) Head circumference B and Left tragion - Vertex - Right tragion circumference which are generally length and width in choosing swimming headgear size were selected as measurement items far size of swimming headgear. Direct measurements and sizes of four swimming headgear with different materials taking into account their elongation rate were also compared.

  • Monitoring fetal growth in utero is crucial to anomaly diagnosis. However, current computer-vision models struggle to accurately assess the key metrics (i.e., head circumference and occipitofrontal and biparietal diameters) from ultrasound images, largely owing to a lack of training data. Mitigation usually entails image augmentation (e.g., flipping, rotating, scaling, and translating). Nevertheless, the accuracy of our task remains insufficient. Hence, we offer a U-Net fetal head measurement tool that leverages a hybrid Dice and binary cross-entropy loss to compute the similarity between actual and predicted segmented regions. Ellipse-fitted two-dimensional ultrasound images acquired from the HC18 dataset are input, and their lower feature layers are reused for efficiency. During regression, a novel region of interest pooling layer extracts elliptical feature maps, and during segmentation, feature pyramids fuse field-layer data with a new scale attention method to reduce noise. Performance is measured by Dice similarity, mean pixel accuracy, and mean intersection-over-union, giving 97.90%, 99.18%, and 97.81% scores, respectively, which match or outperform the best U-Net models.
