  • In the determination of suitable frame sizes associated with dynamic framed slotted Aloha used in radio frequency identification tag identification processes, the widely imposed constraint $L=2^Q$ often yields inappropriate values deviating far from the optimal values, while a straightforward use of the estimated optimal frame sizes causes frequent restarts of read procedures, both resulting in long identification delays. Taking a trade-off, in this paper, we propose a new method for determining effective frame sizes where the effective frame size changes in a multiple of a predetermined step size, namely ${\Delta}$. Through computer simulations, we show that the proposed scheme works fairly well in terms of identification delay.

  • The purpose of this study was to develop a grading increment at armhole area by apparel CAD(Computer Aided Design) system. In developing a grading increment at armhole area, we analyzed ease values of armhole area in bodice and sleeve by manual drafting patterns of five sizes. We suggested grading increments applied Pythagorean theorem to development the grading increment of the armhole of sleeve. The results and discussions of this study were as follows: 1. In drafting each size, the ease values were not identical. It was difficult to draft perfectly the same armhole line shape between sizes. 2. According to our developed grading increments applied Pythagorean theorem, the ease values were identical between sizes and difference of the armhole length between sizes was also identical. 3. The grading formulas were made out for apparel CAD system. Once grading increment or formula is set in the computer, it can be easily altered to various clothing items at any time. The efficiency of grading work will be also improved and grading time will be reduced.

  • The purpose of this study was to review materials that could provide basic data about sports brassieres. In this study, 486 sports brassieres were collected online from 31 brands between November 2015 and February 2016. First, the comparison of compression and encapsulation in sports brassieres identified many different styles. The characteristics of compression brassieres included a cut cup, the front center height of a full cup, round neckline, short front hem, all in one shoulder strap with a patterned racerback design, all in one closure, no wire, and separation cup styles. The characteristics of encapsulation brassieres included a V-shape neckline, mixed round shoulder strap design, back closure, and all in one cup. Second, the comparison of domestic and international sports brassieres sorted the items differently. The characteristics of domestic products included compression brassieres, non-cut cup, the front center height of a full cup, round neckline, short front hem, an all in one shoulder strap with a patterned round design, all in one closure, no wire, and a separation cup. The characteristics of international products included a cut up, racerback shoulder strap design, and an all in one cup. Third, the analysis of domestic and international sports brassieres sizes found that six options were available for domestic compression sports brassieres and nine sizes were available for international products. Domestic encapsulation sports brassieres offered five under bust sizes and five cup sizes. International products offered eight under bust sizes and sixteen cup sizes.

  • The purpose of this study was to research on breast shape and size to suggest a brassiere sizing chart for elderly women. For this purpose 90 elderly women aged between 55 and 69 were sampled at random to review their breast types by age group, and thereby, suggest the basic measurements and production ratio of each brassiere size in reference to KS K 0070: 1999. The collected measurement data were processed statistically using the SPSS PC/WIN program for technical statistical analysis. The results of this study can be summarized as follows; 1. Analysis of Breast Measurements To find out difference among age groups, the 90 subjects were grouped into three(Group 1 ; aged 55 to 59, Group 2 ; aged 60 to 64, Group 3 ; aged 65 to 69). The results of the comparative analysis of anthropometric data from three groups show that getting older;- Various length measurements related to the drooping degree of breast were increased. It was found that the older group in their 65-69's had more drooping breasts than their 55-59's or 60-64's counterparts. Such findings suggests that older women's drooping can be corrected by a brassiere which serves to support the breasts. 2. Suggestions on a Brassiere Sizing For the basic measurements of brassiere parts for the elderly women, the correlation between underchest circumferences and cup sizes were analyzed. 3% or higher occurrences among the whole sample elderly women were included in the brassiere sizes. thus, the under-chest measurements were set at four intervals from 75 to 95, while the cup measurements were determined also at four intervals from "AAA" to "B" sizes. The resultant 6 sizes excluding the least frequent occurrences covered 73.2% of the sample elderly women actual breast sizes. As a consequence of reviewing the production ratio of each brassiere size for the women, it was found that the brassiere size of highest production ratio was "85A" (17.4%), followed by 80A (14.5%), 85AA 90A (10.1%) and 75A (8.7%) in their order.

  • This study intend to analyze differences between 3D body scanning sizes and direct measurement sizes of same subjects. The subjects of study are female students of university in China. 3D data analyze as a 3D Body Measurement Soft System. The conclusion found is as below: In case of circumferences, error between direct-measurement size and 3D body scanning size is from 4.9mm to 62.2mm. The neck circumference size of directmeasurement is bigger than 3D body scanning size. The height error range is from 0.6mm to 51mm. Height of underbust, waist and hip are that direct-measurement sizes are higher than 3D body scanning sizes. Gap of width is from 3.8mm to 21.9mm. The gap range is too narrow relatively to others. Only direct-measurement size of neck width is wider than 3D body scanning size. Error range of length is from 0.3mm to 41.8mm. 3D body scanning sizes of lateral neck to waistline, upperarm length, arm length, neck shoulder point to breast point, shoulder center point to breast point, lateral shoulder to breast point are longer than direct-measurement sizes. They have a negative margin of error. I intend to set up same measurement point between direct-measurement and 3D body scanning but they have some errors because direct-measurement point is applied by a person. 3D body scanning measurement point is settled by automatic system. A measurement point of direct-measurement and 3D body scanning isn't unite. So we need to make a standard of setting up measurement points.

  • The purpose of this study is to survey and analyze the general conditions of infants' apparel brands in Korea, review the sizes and specifications of each brand, analyze the differences and correlations among brands, and thereby, present the reasonable sizes and specifications for infants' apparels in consideration of domestic and foreign specifications and infants' health conditions. for this purpose, 13 brands manufacturing the apparels for the infants aged from 0 to 4 were sampled, and their design directors and outside pattern suppliers were surveyed through direct interviews. The collected data were processed for frequencies, mean, median and mode. The results of this study can be summarized as follows; 1. The sample infants' apparel brands were mostly launched as national brands in 1990's, while their target ages were diverse : 0 $\sim$ 72 months, 0 $\sim$ 36 months, 0 $\sim$ 48 months, 0 $\sim$ 60 months, 12 $\sim$ 24 months, etc. 2. More brands were restructuring the pattern suppliers' sizes and specifications rather than developing them directly, which suggests that most of infants' brands depend much on pattern suppliers. 3. Infants' apparel brands were presenting the 'space suites' sized from #60 to #90 because consumers prefer those space suites distinct in their upper and lower parts and convenient for their toddlers aged 36 months or older. The brands were setting the sizes for 6 parts: total length, breast, sleeve length, hip, hip height, leg. 4. The sizes for infants' one-pieces were #70, #75, #80, #85, #90, #95, #100, #110 and #120, while their subsizes were determined for 4 parts: total length, breast, sleeve length, hip.

  • A machine vision-based instrument to measure a droplet size spectrum of a spray nozzle was developed and tested to evaluate its accuracy on measuring spray droplet sizes and classifying nozzle sizes. The instrument consisted of a machine vision, light emitting diode (LED) illumination and a desktop computer. The illumination and machine vision were controlled by the computer through a C++ program. The program controlled the machine vision to capture droplet images under controlled illumination, and processed the droplet images to characterize the droplet size distribution of a spray nozzle. An image processing algorithm was developed to improve the accuracy of the system by eliminating random noise and out-of-focus droplets in droplet images while measuring droplet sizes. The instrument measured sizes of the three different balls (254.0, 497.8 and $793.8\;{\mu}m$) and the measurement ranges were $241.2-273.6\;{\mu}m$, $492.9-529.6\;{\mu}m$ and $800.8-824.1\;{\mu}m$ for 254.0-, 497.84- and $793.75-\;{\mu}m$ balls, respectively. Error of the measured droplet mean was less than 3.0 %. Droplet statistics, $D_{V0.1}$, $D_{V0.5}$ and $D_{V0.9}$, of a reference nozzle set were measured, and droplet size spectra of five spray nozzles covering from very fine to extremely coarse were measured to classify spray nozzle sizes. Ninety percent of the classification results of the instrument agreed with manufacturer's classification. A comparison study was carried out between developed and commercial instruments, and measurement results of the developed instrument were within 20 % of commercial instrument results.
