This study was initiated to develop a uniform design suitable for child inpatients. The experimental hospital inpatient uniform design was developed based on the results of the prior studies. The panel was composed of 5 experienced nurses and 5 clothing specialists. They evaluated the function of the experimental inpatient uniforms developed in this study. The experimental hospital gown design was reformed based on the panel's evaluation.1'hen the child inpatients performed the wear test for the reformed experimental hospital gown. The results of the study are as follows; 1. The child inpatient hospital gown design of the most hospitals were similar to the adult patient's uniform : the V-neckline shirts with full length set-in sleeves. The bottom was full length pull-on pants. The fabric was white cotton with blue hospital logo and stripe print in most cases. 2. The panel's specialty affected the evaluation of the uniform design. The nurses concerned about the durability after washing and ease for medical treatment. The clothing specialists cared about the features related to the clothing construction and ease for physical movement of body. 3. The most preferred hospital inpatient uniform design by the panels was the shirts or one- piece gown with three-quarter length sleeve and overarm seam opening. 4. The researchers developed one-piece dress gown for the children under two years old. Three different size pajamas were developed for children 2∼5 years old,5∼8 years and 8∼12 years old.

Traditional wedding dresses have had a high market demand in China in recent years. Traditional wedding dresses from the Tang dynasty occupy an important position among traditional Chinese dresses, and they are also favored by young women. This study was conducted to develop the rushan and qun patterns of traditional wedding dress styles from the Tang dynasty for women in their twenties in China. For this purpose, the rushan and qun patterns of Tang and Song dynasty dresses and modern traditional dresses were collected and analyzed. Additionally, the developed patterns were validated for suitability through appearance evaluations of virtual and real fittings. The following proportions of the developed patterns were proposed: H/3.3 for rushan length, H/33 for collar width, H/1.08 for total sleeve length, H/6 for sleeve width, H/8.5 for sleeve hem width, and H/1.55 for qun length. In addition, the developed patterns received high scores in the appearance evaluations of the virtual and real fittings. Therefore, the developed rushan and qun patterns are expected to have high utility in the current traditional wedding dress industry.

The women's apparel sizing system, currently used in the Korean industry, does not reflect measurement differences associated with varying body types and age. Forty five body meaqsurements were taken on 560 subjects, whoes eages ranged from 18-24. STatistical analysis of the data was coducted by using frequences, crosstables, correlation, oneway ANOVA, Regressio analysis. The results of this study were as follow. 1. Average height of women in their early 20's is 160cm, average bust girth 82cm, average hip girth 90cm and average drop 809. The correlation between height and grth items were low and the correlation of length items in the superior and inferior body were shown to bo high respectively. 2. The average Rhrer index is 1.28 and they ussually seem to be in the thin and standard body group. 3. body types were divided by differences between hip and bust sizes. N type(medium hip), A type (large hip), H type(small hip). A classification by body type showed that N type made up 58% while a type made up 24%. 4. The garment sizes for women in their early 20's were developed. 5. The new basic blocks and garment sizes for women in their early 20's were developed as follows : Bust girth (1/2) = 76N, 76A, 79A type($\frac{1}{2}$B+ 4cm) 79N type($\frac{1}{2}$B+ 3.5cm) 82N, 85N type ($\frac{1}{2}$B +3cm) Hip girth($\frac{1}{2}$) =N type($\frac{1}{2}$H + 2~2.5cm) Atype($\frac{1}{2}$H +1.5~2cm) Waist girth($\frac{1}{2}$)=$\frac{1}{2}$W + 2-3cm Back length =extimated measure -0.5cm Front length=76A, N (Back length + 2.2cm) 79A, N(back length +2.7cm) 82N(Back length +3.2cm) 85N(Back length + 3.7cm) Sleeve length=Sleeve length +3cm.

A control system for crop cutting in Hot strip Mill is developed. The development system is composed of three sub-systems. one is crop shape system which captures the shapes of the strip's head and tail using the area CCD camera. Another is Laser Speed System which measures the speed and length of strip. and, the other is control system which controls the optimal cutting length and crop shear motor. As a result, with a developed system we can reduce crop loss considerably.

Jurassic granites of three sites, Pocheon, Geochang and Habcheon, were analysed with respect to the characteristics of the rock cleavage. Microscopic analysis for the oriented thin sections of the specimens was conducted by using the scanline survey technique to measure microcrack direction, spacing and length. The results showed that the preferred orientations of microcrack developed in quartz and feldspar arc coincident with the orientation of quarry planes. The length of microcrack is related to grain size. The length of microcrack in coarse-grained granite is longer than that in relatively fine-grained granite. In all granites, microcracks related to the preferred orientations are well developed in order of rift, grain and hardway planes in number, length and density.

Reinforced concrete structures require large amounts of concrete and rebar in the construction stage. Rebar is a major resource for reinforced concrete structures, and generates more CO₂ per unit weight than other materials. To solve this problem, it was confirmed that the cutting waste can be close to zero when the special length of the rebar is calculated in the drawing created after structural design. However, a system for automatically calculating the length of reinforcing bars to efficiently calculate the total amount of reinforcing bars has not been established. Therefore, the objective of this study is a basic study of automatic rebar length estimate algorithm of bearing wall by using BIM-based shape codes built in Revit. The bearing wall rebar can be automatically derived using the developed model. Furthermore, through applying the developed model to the construction field, it will greatly contribute to reducing greenhouse gas emissions by reducing rebar cutting waste.

This study was conducted to suggest an appropriate jacket bodice pattern for elderly women by comparing the developed pattern with existing ready-made jacket pattern. The developed jacket bodice pattern was produced from the basic sloper in which elderly women's somatotype was fully reflected, by using the newly developed 3D pattern design system. Subjects were 6 elderly women aged from 60 to 69 who have average somatotype in their age group. This study carried out pattern analysis and self-sensory test with three ready-made jackets(national brands) and suggested a developed jacket pattern based on the results. According to the self sensory test results of ready-made jacket, wearing fitness among brands was significantly different even though those brands were same B91 size. The results of ready-made jackets' pattern analysis, size differences among patterns have influenced wearing fitness. The basic numerical formula for the jacket pattern considered elderly women's somatotype were as follows; $B/4+2{\pm}0.2{\sim}0.5$(difference of front and back), $W/4+2{\pm}0.2{\sim}0.5$(difference of front and back), H/4+2~7(ease amount), armhole depth B/4, chest width B/6+1, back width B/6+3 and back neck width B/12+0.5. According to the results of the developed jacket's appearance evaluation, it earned higher scores in silhouette and ease amount, confirming that the developed jacket is appropriate for the elderly women. Also, in the evaluation on space length, the developed jacket pattern was evaluated to allow proper space length in all around of measurement parts.
