The purpose of this study was to investigate on the sleeve form variation according to arm movements for elderly women. This study was experimented using the Plaster gypsum. The subjects who were elderly women were divided into three groups according to Rorher Index. Arm movements were five type ($0^{\circ},\;45^{\circ},\;90^{\circ},\;135^{\circ},\;180^{\circ}$) to each the vertical motion in front and in side. The statistical analyses used in this study were Mean, Standard Deviation, Spearman's correlation coefficients, paired T-test, Kruskal-wallis one-way ANOVA and Duncan's multiple range test. The results were as follows: 1) Increasing the movements, the width of the sleeve increased and the height of the sleeve cap decreased but girth of the sleeve cap was not consistant. 2) When varied the rates of the three aspects of the sleeve, the height of the sleeve cap showed the largest variation rate. 3) There was a negative correlation between the height and the width of the sleeve. On the other hand, there was a positive correlation between the sleeve width and the sleeve girth. 4) There were the vertical motion differences between in front and in side on the three aspects of sleeve. 5) The sleeve width and the sleeve girth were different according to somatotypes but the height of the sleeve cap was not different. 6) According to the variation rates of the body surfaces in length of standard lines, the form of sleeve was changed more in the front than in the back. Maximum variation rate showed in the areas of $D_1-D_3,\;E_1-E_3$ in the horizontal lines and $A-E_2$ in vertical lines. 7) According to the comparative drawing of the heights of sleeve cap and sleeve girth, the sleeve basic pattern $S_1(A.H/4)$ was more suitable for the direction $0^{\circ}\;and\;45^{\circ}$. And the basic pattern S_6(A.H/5)$ was more suitable for the direction $90^{\circ}$, the pattern $S_7(A.H/6)$ suitable for the direction $135^{\circ}$, and the pattern $S_8(A.H/8)$ was more suitable for the direction $180^{\circ}$.

The grouted splice steeve has been applied widely due to its superior construction efficiency, such as the unnecessity of post concrete and the large allowable limit to the arrangement of reinforcing bars. However, studies on grout-filled splice steeve still have not been sufficiently peformed. The purpose of this study is to investigate the confining effect of mortar grouted splice sleeve on reinforcing bar, known to strengthen the bond capacity between grout mortar and reinforcing bar. To accomplish this objective, totally 6 full-sized specimens were made and tested under monotonic loading. Each specimens were equipped with strain gauges at the 12 location of sleeve and reinforcing bar. The experimental variables adopted in this study are embedment length and size of reinforcing bars. Following conclusions are obtained; 1) Under ultimate strength condition, the confining pressure of grouted splice sleeve calculated from measured tangential and axial strain of the sleeve is over $200{\sim}300kgf/{cm}^2$ at any location of sleeve and improved with reduction in embedment length of reinforcing bar. 2) Untrauer and Henry's equation which describe bond strength of mortar as a function of its compressive strength and confining pressure, predicted the measured bond capacity of this test within the 5% limits.

This paper presents a detailed theoretical study of the sleeved compression members based on a mechanical model. In the mechanical model, the core protrusion above sleeve and the contact force between the core and sleeve are specially taken into account. Via the theoretical analyses, load-displacement relationships of the sleeved compression members are obtained and verified by the experimental results. On the basis of the core moment distribution changing with the increase of the applied axial load, failure mechanism of the sleeved compression members is assumed and proved to be consistent with the experimental results in terms of the failure modes and the ultimate bearing capacities. A parametric study is conducted to quantify how essential factors including the core protrusion length above sleeve, stiffness ratio of the core to sleeve, core slenderness ratio and gap between the core and sleeve affect the mechanical behaviors of the sleeved compression members, and it is concluded that the constrained effect of the sleeve is overestimated neglecting the core protrusion; the improvement of ultimate bearing capacity for the sleeved compression member is considered to be decreasing with the decrease of the core slenderness ratio and for the sleeved compression member with core of small slenderness ratio, small gap and small stiffness ratio are preferred to obtain larger ultimate bearing capacity and stiffness.

Power shoulder look is most noticeable trend in women's wear in the 09/10 season. Specially jackets with sharper angle and wider shoulder became the best item since then, and were chosen for must-have item by fashion directors. Jacket occupied 50% in power shoulder items. Its shoulder angle was from 0 to 30 degree but items with 15 degree stood out among them. There are three methods to make power shoulder look jackets; shoulder extension method with moving shoulder tip up and sleeve cap height, method of extension and cutting sleeve cap with shorten shoulder length, and method of extension and moving shoulder tip up in the sleeve with shoulder line like raglan sleeve. As a result, shoulder angle is higher, starting point of shoulder line is closer to side neck point and shoulder point is extender to outside for appearance and fit. In shoulder extension method, the arm hole line was drawn with care by matching joining shoulder seam and setting the sleeve into the arm hole. In sleeve cap transformation, it is desired that starting point shoulder angle is moved closely to side neck point. In case of the sleeve with shoulder line, it needs to consider enough ease of shoulder and upper arm. For making patterns of power shoulder look jacket, it need to consider arm hole line, shoulder length, shoulder point position, sleeve cap height and sleeve width with interpretation design facts. In this study, through the analysis clothing construction method of power shoulder jacket, it is of help to pattern making for various power shoulder design items.

Line sleeves, which used to connect ACSR cables when transmission lines were constructing, sometimes cause power transmission failure due to deterioration and corrosion. Therefore, power transmission line should be inspected regularly to prevent national disaster. Current inspection tool detects insertion length of transmission line on line sleeves, the inspection tool includes enormous error by operator. Moreover, the system is not controlled remotely, negligent accident would be caused while inspecting. To deal with those problems, KEPCO reviewed several ways to inspect line sleeves and proposes new method to inspect line sleeve by measuring magnetic flex which penetrate junction of steel and aluminum sleeve. The developed inspection tool is reliable enough to detect eccentric sleeves. Also, the developed inspection device was applied on actual transmission line and verified its effectiveness.

Knee sleeve has been used for prevention of sport injuries as well as rehabilitation. To investigate prevention of sport injuries of knee sleeve, it is important to evaluate balance associated with proprioception. The aim of this study was to evaluate the effects of a knee sleeve with a pad that stimulate to golgi tendon organ (GTO_PAD) on proprioception and balance ability. Five healthy males were participated for the study. They were asked to reenact target angle with Biodex and perform one leg standing with knee sleeve and knee sleeve with GTO_PAD. There was no significant difference in %Target angle, but the value of %Target angle was higher in subjects wearing knee sleeve with GTO_PAD than only knee sleeve, except for one subject. During one leg standing, time duration was increased in subjects wearing knee sleeve with GTO_PAD. The length of center of pressure in x-axis (COPx) and COP in y-axis (COPy) were decreased when wearing knee sleeve with GTO_PAD (COPx : $162.06{\pm}58.99mm$ in knee sleeve vs. $149.03{\pm}45.30mm$ in knee sleeve with GTO_PAD, COPy : $310.79{\pm}115.89mm$ in knee sleeve, $291.57{\pm}76.53mm$ in knee sleeve with GTO_PAD). There was significant differences in INI_transition, steady, and LAT_transition phase (all, p < 0.05). These findings support that wearing knee sleeve with GTO_PAD might enhance proprioception and balance.

School uniform has improved greatly in terms of fit, size, function, and design due to steep competition in the market and the strong interest of researcher, while little effort has been made for physical training uniform, so the objective of this study is to provide basic research data of the training uniform for the improvement of its design and fitness. For this purpose, 327 high school girls provided information on size and design of their uniform, level of satisfaction, the recognized ease in uniform. Most students wore the physical training uniform in another classes and the long sleeved shirt were the most popular one. They often used the uniform for the protection from cold and for comfortable activeness. For a long sleeved shirt, most students preferred raglan sleeve, zip-up collar, straight waist line, and ribbed sleeve cuffs and hem. For long pants, students preferred elastic waist band and ribbed pants cuffs. Currently, the short-sleeved shirt mostly had a shirts collar, ribbed hem, straight waist line with raglan sleeve, but students wanted a round neck and set-in sleeve. For overall level of satisfaction, students showed high satisfaction in terms of function and psychological effect, while aesthetic quality of the uniform was needed to be much improved. Most students evaluated that the circumference of uniforms properly fit or had a little ease, and students considered waist size the most suitable. The long pants length evaluated properly fit or a little long. Students accepted that the ease of summer uniform was more suitable than winter uniform's both at circumference and at length. Depending on students' height distribution, the length of long pants and short pants varied significantly.

The purposes of this study were to identify the periodicity of fashion in modern society and to find the correlation between each detail and bustle constitution through the bustle styles that have been recently revived. For the study of periodicity, fashion plates or pictures in Vogue or in the books related Vogue since 1930 were selected, and were analyzed into bell, tubular and bustle silhouettes that were devided by Young (1937). And for the study of the correlation of detail and bustle constitution, fashion plates and pictures that were related to the bustle in the 19th century and the 20th century were selected, and according to the epoch (19C, 20C) and the use (daytime dress or evening dress), each of them was analyzed. The results were as follows: 1. After 1930, $24{\sim}33$ year amplitude was founded at tubular and bell shape, that proved shorter cycles than Young's. 2. In each characters of clothing details, deep decolletage, undivided waistline, spaced bodice in daytime dress were partly identified the characteristics of 20th century costume. 3. The form of bustle was converted from the complex ornament of the 19th century to the simple shape of the 20th century. In other words, it is necessary that the definition of bustle be changed not the previous definition as the silhouette and instrument but that as the emphasis dimension. 4. The dimensions that showed difference at daytime dress and evening dress were 'existence of collar', 'neckline', 'length of sleeve', 'kind of sleeve' for 19th century, and 'neckline', 'length of sleeve', 'kind of sleeve,' 'length of skirt' for 20th century. 5. Correlations with the bustle constitution and details were shown at bodice and waistline with the complex bustle in the 19th century and at collar and neckline with the simple bustle in the 20th century.
