Clothing must have the individual beauty and the function that one can do one's body movement freely. therefore, from the human engineering view point, the exact measurement of the human body and the analysis of it's results must be applied to clothing because the arm works most. In this study, the skin surface of arm was investigated by shell made of Alginate of each movement. And by sometic method the rate of expansion and contraction of each section, inter-relation among the bust girth, axillary arm girth and scye girth and between the shoulder length right and the under axilla waist length were calculate4d. With these results, cap height, breadth of a sleeve and arm hole girth of existing sleeve pattern have been compared and analysed. The results are as follows; 1) According to the developmental figures of shell, the whole area change was small but that of shape was remarkable in M 4, 9, 13. The change of the Block 1 was particular. 2) Over arm length was contracted in all movements except M6 and under arm length expanded. The changes of sections a, b, c are large, while those of sections d, e are small. 3) In terms of latitudes, change of fore-arm region was small. The rate of scye girth varied from 14.3% of M13 to-5.6% of M2. The breadth of a sleeve expanded in all movements, and especially the front region expanded more than the back. 4) The relation between the shoulder length right and under axilla waist length, in all occasions, was contracted mutually, and one contracted, the other expanded. Therefore, in clothing construction when we consider the function of the arm it is better to widen the arm hole and the breadth of a sleeve at the same time than no widen the shoulder length by lowering the upper part of the upper side seam line.

This study aimed to develop a new Hanbok Jeogori prototype based on design extracted through a preference survey on new Hanbok Jeogori. This study was conducted based on K-patterns selected as excellent patterns in prior research and utilized the SPSS 27.0 program for analysis of appearance evaluation. As a result of the first appearance evaluation and garment pressure evaluation, the shoulder area was required to be modified, so the shoulder end point was moved within 1cm to rearrange the armhole line. Modification of sleeve length and circumference was also required, reducing sleeve length by 1.5cm and sleeve circumference by 0.5cm at both ends. As a result of the second evaluation, the length of Jeogori, hem circumference, and sleeve length were required, reducing the length of the front and back Jeogori by 1 cm and reducing the sleeve length by 1cm. The hem circumference was reduced by 0.2cm each in the princess line, which was highly evaluated in the final evaluation. In future research, it is thought that pattern studies by material, length, and age should be conducted and corrections should be derived through actual wear experiments.

Girls' school uniform evaluative criteria and their uniform modification were investigated. The data were collected by questionnaire from 579 middle and high school girls living in Incheon during the fall of 2003. The uniform evaluative criteria consisted of five dimensions: aesthetics, comfort, economy, management, and status concealment factor. The uniform evaluative criteria were used to cluster the students into five groups: economic, practical, aesthetic, negative, and active. The uniform modifications were investigated in regard to sleeve length, sleeve width, breast width, jacket length, skirt length, hip width, and waist width. The aesthetic and the active groups intended to modify uniforms less in sleeve length and skirt length than the other three groups. There were significant differences in the uniform modifications among demographics: school years, height, weight, spending money, satisfaction/dissatisfaction with spending money, and clothing expenditures.

The jointing method of PC pile installation, which utilizes steel sleeve, is most popular for the deep bearing stratum( deeper than 15m ) or the irregular bearing stratum depths. However, this method has some difficulties in safety because there is no optimum standards of steel sleeve. This research attempts to determine the optimum standard of steel sleeve for 350mm PC pile, which is most widely used, through bending moment test designated by KS and numerical analysis using finite element method. According to the results, the optimum length of steel sleeve is three times longer than diameter of pile, and the thickness of steel sleeve is more than 2.5mm.

In this study, the tensile strength of 321 full-sized grout-filled splice steeve specimens were compared and analyzed in order to afford the data for a reasonable and economical design of this system. The experimental variables analyzed in this study were embedment length of reinforcing bars, compressive strength of grout, sleeve geometry, loading pattern and final failure mode of specimen. Following main conclusions are obtained : 1) The strength of grout-filled splice sleeve tends to be improved with increasing compressive strength of grout and embedment length of reinforcing bars. Specially this tendency appears apparent in specimens of bond failure rather than rebar failure. 2) The results of this study show that the sleeve geometry have influence on the bond strength of grout-filled splice sleeve. 3) The grout-filled splice sleeve of bond failure don't show the difference of tensile strength according to size of rebar. 4) It is verified that the tensile strength required in ACI and domestic code is retained either when the compressive strength of grout over 70 MPa is used with embedment length of reinforcing bars over 4.5d or when the compressive strength of grout over 80 MPa is used with embedment length of rebars over 3.9d. 5) It is verified that the tensile strength required in AIJ code is retained in case when the embedment length of reinforcing bars is 0.8 times the rebar diameter longer than in ACI code.

This paper presents the findings of an investigation carried out to determine the most appropriate connections, in terms of rotational stiffness, to use for the optimum design of cold-formed Zed section sleeve joint purlin system. Experiments and parametric studies were conducted to investigate the effects of geometric variables on the behavior of the sleeve-purlin and cleat-purlin connections of the sleeve joint purlin system. The variables considered were purlin size and thickness, sleeve size, thickness, length and bolt position. The test results were used to verify the empirical expressions, developed herein, employed to determine the rotational stiffness of connections. With the predicted connection stiffness, the most suitable sleeve-purlin and cleat-purlin connections can be selected so as to produce an optimum condition for the sleeve joint purlin system.

The purpose of this study was to determine the optimal distances between pipes to minimize the pressure loss and turbulent intensity. This was accomplished by investigating the distances between sleeve-jointed pipes and the flow changes in pipes based on variations in the Reynolds (Re) number when installing adjusting pieces for the pipes. When the thickness tp of the sleeve-jointed piping was fixed at 5 mm and the pipe lengths Lp were 10, 50, 100, and 200 mm, the correlations with the velocity of the sleeve-jointed part, pressure distribution, length of the reattachment point in the recirculation area, and Re number were analyzed. The flow characteristic of the sleeve-jointed part from a laminar to a turbulent flow region was determined by setting the Re range to 200 ≤ Re ≤ 5,000. This was done by utilizing Ansys Fluent 18.1, which is a commercial program. The enlargement and contraction ratios of the sleeve-jointed part were 1.2 and 0.83, respectively, and the turbulent intensity of the sleeve downstream edge and pressure change both increased as the Re number increased while Lp remained constant. The fact that the flow on the sleeve wall surface was disturbed by tp resulted in losses in velocity energy. Therefore, the edge of the sleeve-jointed part was also effected. When Lp was 10 mm or less, the turbulent intensity of the edge part did not change significantly as the Re number increased. The reattachment point in the recirculation area did not appear at Lp of 10 mm or less and was not affected by the vortex. In the case of 3,000 ≤ Re, the reattachment length of the wall surface of the sleeve-jointed part was nearly constant as Lp increased.
