The purpose of this study was to provide information on how to improve the current sizing system of infant coveralls through analysis of the present system. In order to compile the information about dissatisfaction with the appropriateness of the fit of infant coveralls, a questionnaire was administered to mothers of 241 infants (aged under 36 months) living in Seoul, and analyzed using the SPSS WIN.10.0 program. Also, the manufacturers'basic body sizes were investigated. The results of this study were as follows : 1. The results of the comparison between the manufacturers'basic body sizes and the body measurement values obtained as the physical standard of the nation(1997) show that in terms of length and hip circumference, the manufacturers'body sizes were larger. On the other hand, in the waist circumference, the manufacturers'body sizes were smaller than the national average. 2. Research on the production sizing system of domestic and international brands, showed that the sizing interval of domestic brands were 6 months, whereas the international brands were 3 months f3r infants under 12 months. 3. Concerning fit, the areas causing most dissatisfaction were: the trunk length, sleeve length, inside leg length, and neck depth. The results showed that dissatisfaction with the suitability of the sizing of current infant coveralls according to the body part differed among the groups according to the month of age.

As background significantly affects measurement accuracy and a detection limit in determination of the trace amounts of uranium, it is necessary to determine the impurities in the Lexan detector film for single particle measurements by thermal ionization mass spectrometry coupled with fission track technique (FT-TIMS). We have prepared various micro sizes of the blank Lexan detector film using a micromanipulation technique for uranium measurements by TIMS. Few tens of fg of uranium background with no remarkable dependency on the film sizes were observed in the blank Lexan films with the sizes from $50{\times}50\;{\mu}m^2$ to $300{\times}300\;{\mu}m^2$. Based on the determination of the uranium background in the Lexan film, any background correction is necessary in the isotopic analysis of a uranium single particle with micron sizes when the particle bearing Lexan film is dissected with less than $300{\times}300\;{\mu}m^2$ size. The isotopic analysis of a uranium particle in U030 standard material using TIMS was carried out to verify the applicability of the Lexan film to the single particle analysis with high accuracy and precision.

This study proposes a new screw measurement system that is capable of measuring the pitch or lead of a screw, which is one of the most important parameters representing the screw quality. There are various conventional methods for screw measurement including some mechanical and optical ones, but they can not be applied to measure the lead except the profiles or sizes. The newly suggested method is able to measure the pitch or lead directly. This is executed by scanning the thread with a digital probe while the target screw rotates. The devised measurement system is a integrated computer system which is composed of a stepping motor, a digital linear gauge and a chuck device for holding the measured screw. In order to operate the system effectively and conveniently, a computer program having graphical user interface facility is developed. Some experiments were done to prove the effectiveness of the system.

This study was aimed at reviewing the preceding studies regarding infants' physical characteristics and comparatively examining their apparel specifications among countries, and thereupon, surveying the sizes and specifications of each special infant apparel brand in korea, and thereby, providing for the basic data useful to consumers when they choose infants' apparel sizes and specifications, and at the same time to brand makers for effective exchange of information. Thus, domestic special infant's apparel brands were surveyed for their own sizes and specifications, and thereby, the basic data useful to consumers when they choose their infants' apparel sizes and specifications as well as to brand makers when they exchange information among themselves were produced. The results of this study can summarized as follows: As a result of surveying the general trend of the infant apparel brands in korea, it was found that 5 brands had been established before 1990's, and that the remaining 7 ones had emerged during 1990's. When viewed in terms of brands' originality, it was disclosed that 10 brands were korean originals, while 2 brands were foreign ones licensed. On the other hand, as a consequence of surveying the target age groups of each brand, it was found that the targe age groups differed much ranging from 0 to 72 months or more narrowly from 12 to 24 months, which means that the infant age has yet to be defined for all the brands. In the case of the domestic infant-clothing product respect of inner wear, 8 clothing companies are producing the the outside clothing. In the outside clothing, from 6 months to 36 months' infant is the object, and 6m, 12m, 18m, 24m, 30m, 36m appeared with the fact that it produces in 6 sizes. In the case of the f and the g company which has the difference of size control is big, the f company is producing infant clothing for the age 0 to 72 months in 6 size which the difference of the measurement between the size is a lot to be appear, on the other hand, the g company is producing infant clothing for the age 0 to 6 months in 6 size which the difference of the measurement between the size is small to be appear.

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 represents the efficient depth measurement for 3-dimensional microsystems using the disparity histogram from stereo images. Implementation of user-friendly Windows program written in C++ involves the various methods for the stereo-image processing in which the minimization of matching-pixel error upon the unique point for stereo images was carried out as a pre-processing method. Even though MPC among various methods was adopted in the present measurement, the resulting measurements seem to require optimizations of the windows sizes and corrections of post-manipulation for stereo images. The present work using Windows program is promising to measure the 3-dimensional depth of micro-system efficiently in implementing the 3-dimensional structure of micro-systems.

This study analyzes the body sizes of young boys in order to categorize a sizing system for middle and high school uniforms. The study was based on the $6^{th}$ National Anthropometric Survey (Size Korea 2010) data. The sample size consisted of 2,317 boys between the ages of 13 and 18 years. Most measurement items increased significantly relative to age and there was rapid growth between the ages of 13 and 14 years. The growth for the chest and hip was more than the waist. The drop value 1 (difference between chest circumference and waist circumference) and the drop value 2 (difference between hip circumference and waist circumference) increased remarkably from the age of 13 to the age of 15. Therefore, the waist size decreased and chest and hip became wider relative to the age increase. Middle school students had a smaller chest and hip circumference than high school students in the comparative body measurement results for middle school students (13-15 years) and high school students (16-18 years) of the same height group. The somatotype of high school students showed a long trunk length, broad chest and shoulder.

The single-scattering optical properties of ice crystals in cirrus clouds by the aircraft measurement data were investigated, and the radiative equilibrium temperatures and radiative fluxes were calculated and analyzed by radiative convective model with the variations of ice crystal habits and sizes in cirrus clouds. The homogeneous cloud is assumed to be in the layer 200~260 hPa with an ice crystal content of $10gm^{-2}$ for the flux calculation. The profiles of temperature, humidity, and ozone typical of mid-latitude summer are used. The surface albedo is assumed to be 0.2 for all spectral bands and the cosine of solar zenith angles is 0.5. The result of radiative equilibrium temperature at surface was less than surface temperature of the standard atmosphere data in case of smaller effective ice crystal size and larger optical thickness. The column, aggregation and plate in 6 ice crystal habits were the most effective in positive greenhouse effect and bullet-4 was the worst in it. At the surface, the maximum difference of equilibrium temperature by 6 kinds of ice crystal habits were about 3~15 K with 30 sample aircraft measurement data.
