This study purport to establish the size was flexibly receptive to consumers. Sample size was 6555 women in their 20's and 29 variables from the diret anthropometric data were applied to analyze. The preliminary survey was taken from Febraury 10. 1997 to May 23 1997 and the measurement was done from April 14, 1997 to June 10. 1997. Follwing the KS regulations Hanbok were given 3cm intervals each for the bust and hip girth and cm for th height. Size system was presented for the usage of developing the pattern of hanbok by analyzing the result of the regression coefficient and referring to the distribution chart of the back length and the neck to ulnar styloid length. When establishing the standard size for the ready-made Hanbok like Western style clothes it's convenient for both consumer and producer to present both bust girth and height. To enhance the fitting of Chogori we used the flatness ratio of bust as the reference for grouping styles of body. in the case of Chima-\ulcorner해갸 4 brackets are developed. First step was bust girth 78cm height 15cm second was bust girth 5852cm5 height 160cm third was bust girth 82cm height 165cm fourth was bust girth 88cm height 16cm.

This study is aimed 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 from 4 to 6 were sampled to be subject to the measurement of their somatotypes. The results of this study can be summarized as follows ; 1 By the analysis of overlapped cross section diagram and silhouette diagram of each somatotype both had a common shape of lean-backed upper troso. 2. The type 1 showed less dimensions in most scales than type 2 while their shoulder were less developed. The type 2 showing more development in each element. 3. As a result of comparing the dress forms designed in reference with classified somatotypes and the commercial ones it was found that the former ones had the upper body part slanted slightly backwards and the belly part extruded forwards while the latter had a straight posture with large shoulder parts. After all the commercial dress forms were found not to reflect the actual somatotypes of Pre-School children's.

Purpose: This study was conducted to comparative evaluate the marginal and internal gap of three-unit metal frameworks(Co-Cr) fabricated by wax milling method and digital light projection method of CAD/CAM systems. Methods: All the specimens were fabricated by three different fabrication methods: conventional wax up with casting(CWC), milled wax block with casting(MWC), digital light projection with casting(DLPC) (n=10 each). The marginal and internal fits of specimens were examined using a replica technique. The light-body silicone thickness was measured at 8 reference points(each abutment: 16 measurements). All measurements were conducted by a stereomicroscope. Digital photo were taken at $150{\times}$ magnification and then analyzed using a measurement software. The Mann-Whitney test was used for analyzing the results. Results: Statistically significant differences were found between the fabrication methods(p<0.001). The mean(SD) is ${\mu}m$ for fabrication methods, the mean marginal fit were recorded respectively, CWC 63(38), MWC group 50(33), DLPC 103(54) and the mean internal fit CWC 96(47), MWC group 116(41), DLPC 138(66). Conclusion : The marginal and internal fit were statistically different according to the fabrication methods(p<0.001).

The suboccipital triangle (ST) is a clinically relevant landmark in the posterior aspect of the neck and is used to locate and mobilize the horizontal segment of the third part of the vertebral artery before it enters the cranium. Unfortunately, this space is not always a viable option for vertebral artery exposition, and consequently a novel triangle, the inferior suboccipital triangle (IST) has been defined. This alternative triangle will allow surgeons to locate the artery more proximally, where its course is more predictable. The purpose of this study was to better define the anatomy of both triangles by measuring their borders and calculating their areas. Ethical clearance was obtained from the University of Pretoria (reference number: 222/2021) and both triangles were subsequently dissected out on both the left and right sides of 33 formalin-fixed human adult cadavers. The borders of each triangle were measured using a digital calliper and the areas were calculated using Herons Formula. The average area of the ST is 969.82±153.15 mm², while the average area of the IST is 307.48±41.31 mm². No statistically significant differences in the findings were observed between the sides of the body, ancestry, or sex of the cadavers. Measurement and analysis of these triangles provided important anatomical information and speak to their clinical relevance as surgical landmarks with which to locate the vertebral artery. Of particular importance here is the IST, which allows for mobilisation of this artery more proximally, should the ST be occluded.

In this paper, we propose a motion and position recognition technique considering an experiential VR environment. Motion recognition attaches a plurality of AHRS devices to a body part and defines a coordinate system based on this. Based on the 9 axis motion information measured from each AHRS device, the user's motion is recognized and the motion angle is corrected by extracting the joint angle between the body segments. The location recognition extracts the walking information from the inertial sensor of the AHRS device, recognizes the relative position, and corrects the cumulative error using the BLE fingerprint. To realize the proposed motion and position recognition technique, AHRS-based position recognition and joint angle extraction test were performed. The average error of the position recognition test was 0.25m and the average error of the joint angle extraction test was $3.2^{\circ}$.

The purpose of this study was to investigate the commonly accepted ease for a custom-fit business jacket, which provides all customers with the optimum fit regarding their individual body sizes, shapes as well as their personal preference, and also to characterize the factors which affects the ease amount, thereby, supply the reference data to manufacturers of the apparel industry. This study consisted of anthropometric measurements as well as sensory evaluations, and analysed ease amount by body sizes, ages, fit satisfaction, self-perception of body, and the prefered fit levels. There were 272 subjects for anthropometric measurement of which 128 subjects were applied for ease analysis and sensory evaluation. The subjects were males of 20 to 65 years old. The ease at chest was the most sensitive to body sizes and shapes, while waist and hip were easily modified to accommodate the silhouette of the jacket. The main dimensions affecting individual perceptions of fit and ease were the characteristics of body shape, in particular, girth, followed by age. Customers paided most attention to the shoulder fit while customers who preferred a more fitted line showed more concern with ease for jacket fit. It was clearly observable in case of waist fit preference. In addition, the preferred fit at chest, waist and hip would be changed by the perception of ons's hip size.

Background : The cun measurement system, an essential and convenient method in locating acupoints, has been widely used in the practice of acupuncture. However, traditional cun measurement has been criticized for its lack of reliability. Objectives : The purposes of this study are to determine if one cun measured by the directional methods have a consistency with that of proportional methods and to investigate which factors are related with these differences, especially in forearm. Methods : The distance between the elbow crease and the wrist crease of forearm was compared to a reference value of one cun obtained by the directional method. In this method, one cun is one third of the distance between index finger and small finger of a subject, measured at proximal interphalangeal joint. In addition, to investigate the factors influencing the differences between these two methods, we measured the height and body weight and calculated body mass index (BMI). Finally we analyzed the factors correlated with these lengths by linear regression test. Results : The results showed that one cun obtained by the directional methods were significantly different from one cun by the proportional methods in forearm. It was demonstrated that the length acquired with the directional method was more correlated with body weight and body mass index, while the length obtained by the proportional method was more correlated with the height. Conclusion : These findings suggest that the directional method is less likely dependable in locating acupoints than the proportional method because the influencing factors are different.
