The results of this study, with the cooperation of Sejung and Searte Companies exporting clothes to Ningbo City, Zhejiang Province in China, are as follows: 1. Corresponding Dimensions of China Women's Clothes According to Morrison's relative deviation method, the body measurement characteristics of Chines and Korean women in their 30s and 40s were compared. As a result, Chinese women were bigger in height, arm length, abdomen girth, and upper arm girth but smaller in shoulder length and shoulder width. The cluster analysis for body type classification was as follows: Type 1, tall and well-developed, was 34.8%. Type 2 with weaker upper body, medium height, narrow shoulders and a slim waist was 45%. Type 3 with stronger upper body, shortest height and wide shoulders was 20.2%. 2. Corresponding Dimensions of China Men's Clothes Based on the drop standard of KS K 0050, the body types of Chinese men in their 20s were classified. A body types were 55.77%, Y body types were 32.16%, B body types were 11.55% and BB body types were 1.51%. According to the criteria of ready-made dimensions of normal body type suggested in Korea Standards, and in consideration of the basic distribution reality of body dimensions, representative 5 sizes were selected. 3. The corresponding size specification of China women's and men's clothes based on those of KS size specification were presented here, showing product sizes and physical items in detail.

The purpose of this study was to classify size specifications of Korean adult male for the men's ready·made garments, especially jacket and dress shirts. Concept of the comfort and fitness has become a major concern in the basic function of the ready-made garments. Data were collected by the real anthropometric measurement and by the photographic sources. Sample size was 1.290 subjects as the sample and their age range was from 19 to 54 pean old by the stratified sampling method. 66 variables from the direct anthropometric data in total were applied to analyze. ANOVA in SAS package was applied to the data and the expected frequency distribution of 10.000 men was calculated by the extraction of density function. Control dimensions for jacket and dress shirts has been designated by Bcorean Apparel Sizing System (KS-K). Therefore this study was performed to classify size specifications by the control dimensions and at the same interval of KS-K. The drop values of 15, 12 and 9 has the high coverage rate of 22.1%, 21.0% and 18.8% respectively and are composed of the majority of 61.9% of the subjects. According to the drop values, size specifications and distribution of control and reference dimensions are predicted. About 65.75% of the expected frequency distribution without stature were covered by 19 size specification.

The goal of this study was to review the visual grading and allowable stress determination methodologies for the domestic softwood. Previous studies used different grading (KFRI 1995-27, KFRI 2000-39, KFRI 2007-3, KFRI 2009-1) and allowable stress determination methodologies (ASTM D 245, KS F 2152, JAS 1990). The results of the visual grading were different by each researcher. Compared to the $1^{st}$ grade proportion from the previous studies using the previous specification on visual grading (KFRI 1995-2007), a higher $1^{st}$ grade proportion was found from the studies using the current specification (KFRI 2009). Compared to the allowable stress values from the small clear sample, the higher allowable stress values from the structural size were found. The results indicated that the strength reduction factor used in small clear sample was too conservative for the different grades. To obtain consistent results for the grade, it is required to have experts in visual grading and authorized organizations. An official standard methodology for the allowable stress value determination needs to be defined for the reliable stress value.

This study collected and analyzed reference information on the size labeling method and size of clothing products in 13 online shopping malls for plus size women in their 20s and 30s, and compared the size specification information focusing on jeans. First, in the results of examining the method of clothing size designation, clothing sizes indicated by 1, 2, 3 or physique designation (M, L, XL) differed between shopping malls, and even in the same shopping mall, even if the same size notation was used. Most the clothing sizes were different depending on the type of clothing. For bottoms, it was found that one company used seven size designation methods at the same time, two shopping malls used four size designation methods, and five shopping malls used three size designation methods. In the meantime, in the results of comparing the size specifications of jeans XL (size 88, 32 inches) by product part, for waist and hip circumferences, each of the eight companies showed that the size was smaller than the body size suggested by KS adult women's wear.

This study was performed to narrow down the Sizing System for Female Adult's garments(KS K 0051) following age target and body shapes. The study was based on the sizing system and the anthropometric measurements, called Size-Korea, which were surveyed in the years 2003 and 2004. At first, the subjects of the survey were classified into 4 age groups, $18{\sim}24,\;25{\sim}34,\;35{\sim}49\;and\;50{\sim}59$, based on the most significant differences of body sizes. Secondly, the ranges of four key dimensions - height, bust, waist and hip-of normal sizes were identified through analyzing Rohrer index and percentile. The selected sizes within the ranges were grouped by the drop which was the subtraction of bust girth from hip girth. In conclusion, there was the most frequent drop for each age group; 9cm drop for the $18{\sim}24$ years old group, the 6cm drop for the $25{\sim}34$ years old and $35{\sim}49$ years old and 3cm drop for $50{\sim}59$ years old. The upper body garment sizes of the same drop and target ages could be merged to 10 to 12 sizes, which were remarkably smaller than the Female Adult garment sizing system, and further to 2-5 sizes, considering the percentile importance. However, $50{\sim}59$ years old group needed to be analyzed in different ways, because the number of subjects of normal size in the age decreased rapidly, that the normal sizes for them were very limited. In addition, the reference body sizes of each garment size were apparently different when they were compared to each age groups. These basic data for garment size specification could be usefully adapted for the apparel companies' own sizing system according to their age target and body shapes, to achieve efficient production and better fit.

The purpose of this study is to analyze the foot shape and size specification of male high school students. 3D modeling programs such as 'Artec Studio', 'CATIA', and 'Auto CAD' measured the 3D scan data of 361 male high school students provided by KATS. Through principal factor analysis, 10 factors were extracted, including foot length, medial-lateral ratio, and foot length ratio. As the result of the cluster and ANOVA with post-hoc test (Duncan method), the differences among types were clarified. Type 1 (24.7%) represented outward medial-lateral ratio (M-L ratio) with the lowest instep, ankle and little deformed first toe. Type 2 (41.8%) was characterized by the shortest, even M-L ratio, thin ankle and heel, the highest instep and ankle. Type 3 (33.5%) showed the longest, inward M-L ratio, thick ankle and heel, and deformed first toe. As the cross-tabulation of foot length and ball circumference, 17.2 percent was not covered by KS standard; in addition, the foot length was longer than the KS standard. The correlation analysis of key dimensions showed that foot length and ball circumference were highly correlated with other items; therefore, regression equations were derived to estimate other foot measurements using these two items as independent variables.

Sizing system of Korean structural firefighting protective clothing that is national approved should be met for specification of structural firefighting protective clothing that is identified by Ministry of Public Administration and Security(MOPAS). However if you look over the specification of sizing system, the standard is based on only 'height' and the others are indicated as the size of completed product. KS K ISO 13688 and EN 340 which is met on ISO 13688 which indicates sizing system about protective clothing has the standards of height, chest and waist circumference. Also NFPA 1971 that has standards of sizing system is based on chest circumference, cervical to wrist length, waist circumference and inseam. That is different from Korean standards. Therefore, fire fighting protective clothing standards which is based on only height should be compensated and not be relied on foreign standards like ISO. It is indispensable for developing our own sizing system of structural fire fighting protective clothing. In this studying, Korean new sizing system of structural fire fighting protective clothing was developed for providing basic information of ergonomic structural fire fighting protective clothing. The analyzed target age was between 20 and 59 years old fire fighter who extinguish the fire. And it was analyzed by 3D measurement among data of the $5^{th}$ Size Korea. On conclusion, in case of structural fire fighting protective clothing coat, physical dimension was to be chest circumference, cervical to wrist length. Three dimensions as 5cm space of circumference and four dimensions as 2.5cm space of cervical to wrist length were derived, which means that totally 12 dimensions were defined. Dimension standards of pants was based on the analysis of waist circumference and crotch height. Six dimensions as 5cm space of waist circumference and three dimensions as 5cm space of crotch height were derived, which means that totally 14 dimensions were defined.
