In the stacking and pitching items of the stone masonry and demolition process presented by 2018's standard of estimate, 7 estimating standards are presented according to the depth of masonry stone, and it is presented that the quantity per unit increases as the depth of masonry stone grows. As a result of analyzing the application status in the site, it is shown that 2 or 3 stones are mainly used according to the stone sizes regardless of the depth of masonry stone, and that as the size of the stone becomes larger, the quantity per unit decreases due to the size per square meter(㎡). Also, in most of sites, machine construction is mainly carried out by excavators with clampers attached to them. Therefore, in the 2019's application standard of estimate, it is analyzed that the size is simplified down to 3 sizes reflecting the site application status and that it is revised as a standard reflecting the result that as the stone size becomes bigger, the productivity increases.

국내의 장애인들이 많이 사용하고 있는 보조기구 중의 하나인 전동휠체어는 우리나라의 KS P ISO 7176-5 규격의 치수를 따르고 있으며, 이 규격의 경우 국제 규격인 ISO 7176-5의 규격을 기술적 변경 없이 그대로 사용하고 있다. 하지만 국제규격의 경우는 외국의 신체사이즈를 기준으로 휠체어에 대한 크기를 규정하기 때문에 국내에서 사용하기에 적합하지 않으며, 이로 인해 움직임의 제한 또는 골반의 회전으로 인한 자세 불균형, 허벅지에 과도한 압력으로 인한 욕창 발생 또는 오금 및 장딴지에 과도한 압력으로 인한 욕창발생, 바르지 못한 자세로 인한 안전성 감소 등이 발생한다. 본 논문에서는 기술표준원에서 조사된 연령별 인체치수를 토대로 전동휠체어의 권장휠체어 치수를 제안하였으며, 이는 KS P ISO 7176-5에 규정된 치수와는 많은 차이를 보이며, 전동휠체어 치수에 대한 재규정이 필요하다.

Objective: The purposes of this study were to evaluate size-specific dose estimate (SSDE) of low-dose CT (LDCT) in the Korean Lung Cancer Screening (K-LUCAS) project and to determine whether CT protocols from Western countries are appropriate for lung cancer screening in Korea. Materials and Methods: For participants (n = 256, four institutions) of K-LUCAS pilot study, volume CT dose index ($CTDI_{vol}$) using a 32-cm diameter reference phantom was compared with SSDE, which was recalculated from $CTDI_{vol}$ using size-dependent conversion factor (f-size) based on the body size, as described in the American Association of Physicists in Medicine Report 204. This comparison was subsequently assessed by body mass index (BMI) levels (underweight/normal vs. overweight/obese), and automatic exposure control (AEC) adaptation (yes/no). Results: Size-specific dose estimate was higher than $CTDI_{vol}$ ($2.22{\pm}0.75mGy$ vs. $1.67{\pm}0.60mGy$, p < 0.001), since the f-size was larger than 1.0 for all participants. The ratio of SSDE to $CTDI_{vol}$ was higher in lower BMI groups; 1.26, 1.37, 1.43, and 1.53 in the obese (n = 103), overweight (n = 70), normal (n = 75), and underweight (n = 4), respectively. The ratio of SSDE to $CTDI_{vol}$ was greater in standard-sized participants than in large-sized participants independent of AEC adaptation; with AEC, SSDE/$CTDI_{vol}$ in large- vs. standard-sized participants: $1.30{\pm}0.08$ vs. $1.44{\pm}0.08$ (p < 0.001) and without AEC, $1.32{\pm}0.08$ vs. $1.42{\pm}0.06$ (p < 0.001). Conclusion: Volume CT dose index based on a reference phantom underestimates radiation exposure of LDCT in standard-sized Korean participants. The optimal radiation dose limit needs to be verified for standard-sized Korean participants.

Reduced activation ferritic steel (JLF-1) is considered as a promising candidate material for blanket or first-wall structure of D-T fusion reactors. The fracture tests of fracture resistance curve (J-R curve) and $J_{IC}$ are desirable to investigate the exact fracture toughness of JLF-1 steel, since it has a high ductility. The fracture toughness of JLF-1 steel is affected by the configuration of test specimen such side groove, specimen thickness or specimen size. In this study, the fracture toughness tests were performed with various size(plane size and thickness) and various side groove of specimens. The test results showed the standard specimen with the side groove of 40 % represented a valid fracture toughness. The fracture resistance curve increased with increasing plane size and decreased with increasing thickness. However, the fracture resistance curve of half size specimen was similar to that of the standard specimen.

The objective of this study is to establish a standard size for clothing construction and to develop a basic bodice pattern for Misses. 1. Seven kinds of pattern generally used in Korea were collected and compared in the aspect of items of necessary measurements and application of measurements to pattern drawing. 2. 209 girls aged 17 to 25 were measured on 22 items. The measurements were analyzed by calculation of means, standard deviations, co-variance, range, maximum, minimum, and correlation co-efficient between each item. the data were classified into four size groups according to bust size. Correlation co-efficient between each item were as follows: 1) Correlation co-efficients of bust to upper bust and waist were very high. 2) Correlation co-efficients of bust to shoulder width, across back and across chest were relatively high (r=.6385, r=.7493, r=.6344, respectively). 3) Bust had little correlation to neck and shoulder slope.

KS K 0051(2009) was established in 1990 and revised in 1994, 1999, 2004 and 2009. Recently the structure of apparel production and distribution are changing like as small quantity batch production, increase of importing abroad apparel and increase of on-line shopping mall. Based on Social and economic conditions, examine the potential for use of KS K 0051(2009) standard sizing system for female adult's garments are needed. Through which, it was intended to suggestion for the revision of standard sizing system for female adult's garments which can facilitate communication among consumer, producer and sellers. The improvement point was discussed through review of the current KS K 0051 (2009) and abroad standard sizing system for female adult's garments, ISO 3637(1977), ISO 4416(1981), BS EN 13402-2(2002), BS EN 13402-3(2004), JIS L 4005(2001) and GB/T 1335.2(2008). Also, the revision of standard sizing system for female adult's garments was suggested using data of 6th Size Korea. As a result of this study, in the revision, formal wear, casual wear, training wear and under wear were separated to simplify the classification and the classification of body type were excluded. Also, it is possible that size designation was simplified through optional notation and letter code based on bust girth could be marked together in casual wear.

The purpose of this study is to analyze of size and patterns of ready to wear basic for middle age women. For this purpose, I select 9 brands and analyze the basic skirts size system marketed in 2002 spring in Korea. To study the actual size system, I have compared size labeling, which I researched, with Korean Industrial Standard Size Chart. And I also have compared body measurement with the product size. To study the pattern, I have classified the composition of the skirt into 24 items. The different result shows between this study and Korean Industrial Standard Size Chart. The waist circumference is smaller than it should be, and the hip circumference is larger than it should be. As I have examined the body measurement and the product size, variability of the waist circumference depends on the location of the waistline. For the hip circumference, I have found that both the body measurement and the product size are same, or the product size is smaller than the body measurement. Both cases have been found to be over 67%. I have classified the analysis of the pattern into four components; circumference, relevance to waist line, dart, and length. For the waist circumference, the same size of the front and the back is 44.4%, and making the front larger is 44.4% also. In the hip circumference, the identical size of the front and the back is 66.7% and the larger size of back is 22.2%. Regarding darts placement, it is moved to the side lines from the middle of 1/2 of waist lines, dart intake was 1.3~3.2 cm, the length of darts is 7.2~12.7 cm.

The research, aiming an automatic pattern design of Korean Costume by utilizing CAD system, tried Grading, Seaming and Marking with a theme of girl's color-strip blouse & skirt. The content & conclusion of the research can be outlined as follows; 1) As we reviewed the current situation of Korean costume which becomes more likely celebrational or festival costume, while the demand of it is getting increase, it's being dealt mostly as ready-made dresses with different qualities & designs. Especially childrens ready-made ones were highly demanded to be picked up as the theme. 2) For the original drawing of children's color-strip blouse & skirt, Kyung-Ja Park's drawing method was used here, and for the substitute of particular body parts absolute size, Joo-Won Lee's standard size chart from a size-study by ages. 3) To work with CAD system we had input master pattern, drawn for age 5 as basic size, then graded six step-sizes for 1-11 years old. For add-subtract of particular body parts size, we graded through computing the standard variation among items to get the pattern developed into ready-made standard size, we can make precise plotting by grading wanted size very rapidly if we correct the rule of changed items different from standard size to make utilization possible enough with easy order method of ready-made Korean Dress. 4) We produced Marker after attaching a margin to seam accordingly by parts for each pattern using P/D/S to mark, In mass gament-cutting, the loss of time and material can minimized. In this research the apparel CAD system which has been utilized and only be western fashion industry was introduced for the design of ready-made Korean costume and utilized it in Grading, Marking which are critical steps to improve productivity and have reported the result in the research. Thus we expect that less cost, improved productivity and better quality with minimized loss of material from marking as well as from prompt and precise size-drawing. Furthermore the utilization of CAD system is considered as an effective one in terms of the research & the development to remove effective one in terms of the research & the development to remove irrational elements in the design and production process of Korean costume as well as in terms of the study of Korean Costume development through creative works of Korean Costume.
