As an exaggerated-shoulder becomes a growing trend women's clothing, the crescent shaped sleeve with parallel style lines in the arm hole is a highly used women's sleeve pattern. This study develops and provides an applicable method for making the crescent shaped power shoulder sleeve. An efficient basic method for making the 2 piece crescent shaped sleeve was developed and the sensory appearance test was carried out with experimental clothes. There are two principles for making the crescent shaped sleeve: having a style line in the sleeve and pasting part of the cut arm hole of the bodice to the sleeve. The latter would be more convenient for a 2 piece sleeve, mostly used for jackets. The crescent shaped sleeve used in power shoulder jackets should set the shoulder angle as you wish to extend and raise the shoulder point of the bodice and sleeve to the same height. For a stronger power shoulder image, a 3 piece sleeve has a better appearance. Also, the height of the shoulder has to be enhanced with a shoulder pad for a more stable sleeve.

This study investigated the annual frequency and clothing type by extracting puff sleeves designs from overseas fashion collections from S/S and F/W 2017 to S/S and F/W 2019. Specifically, it analyzed production characteristics and pattern methods by the type of puff sleeve design, and found the following: In terms of the percentage of puff sleeves by season, S/S 2019 was the highest. Since Newtro, with a 1990s sensitivity, was the mainstream trend during the S/S 2019, power puff sleeves, a signature of the Newtro style, accounted for the greatest portion of this design feature. In terms of the type of clothes with puff sleeves, 'dress' (54.3%) was the highest, followed by 'shirts/blouse' (27.5%), 'jacket/coat' (12.5%), and 'padded coat/jacket' (5.7%). Specifically, puff sleeve patterns were found mostly in the 'dress' category, more than 47% every season, while the figures were more than 23%, 9.3%, and 2.6% in 'shirts/blouse', 'jacket/coat' and 'padded coat/jacket', respectively. In other words, puff sleeve designs were more common in 'dress' or 'shirts/blouse' than in a 'padded coat/jacket'. In general, the shoulder length is reduced to prevent the shoulders from looking broader because of puffs. In contrast, recent puff-sleeve styles differ from those introduced by modern fashion designers in that they have drop shoulders with puffs attached. Furthermore, as constructive and over-exaggerated sleeve patterns appeared, puffs were applied to diverse sleeve styles including mutton leg and Mameluke styles. The analysis results of this study will contribute to the development of the fashion industry through small quantity batch production pursuing unique styles and serve as the basis for further studies on the configuration methods of puff sleeves. This study will be used in various ways, including as educational material on sleeve patterns. Through the analysis of sleeve patterns, this study tries to provide basic data for planning the design of puff sleeves and helping to diversify the ladies' apparel market in the future.

This paper presents the design method of a planar sleeve monopole antenna on PCB, which has wider bandwidth compared to that of the conventional sleeve monopole antenna, by showing the fact that the sleeve of the conventional antenna can be simplified in structure. The designed and fabricated planar sleeve monopole antenna's structure is very simple, with a monopole adjacent to a small square sleeve on FR4 PCB. The antenna shows 46% wider bandwidth compared to the corresponding 3-dimensional one with nearly omni-directional radiation property.

As a shot sleeve in die casting plays a critical role in delivering molten metal to a die cavity, any disruption to its function in the injection stage results in deterioration of the quality of final castings. To guarantee a smooth operation of a shot sleeve, its structural stability should be maintained. Despite the simple geometry, design of shot sleeve is based on individual engineer's experience and no agreement on the design is present. In this study, we newly propose a systematic methodology to determine a minimum wall thickness of a shot sleeve to prevent yielding or plastic deformation. Analytical calculations incorporating numerical analysis produce a rational design rule for minimum thickness of a shot sleeve subject to metal intensification pressure and geometric die constraint. To validate the proposed design guideline, authors present real data on a collection of actual shot sleeves. Upon checking their conformity to the new design rule, we discovered a strong correlation between the design of wall thickness and premature failures.

This study devised and drew custom sleeve patterns by using a regression equation with the data from 7 models along with the sleeve that was slightly modified to make the general-purpose sleeve pattern. To devise a general-purpose sleeve pattern, the sleeve pattern was drawn as an object for comparison by applying the Bunka drafting system (sleeve pattern by the Bunka drafting system) to the basic upper garment. Actual sleeves, made by using the three types of patterns above, were created and tested by models. Next, 30 panel members participated in a sight test of the compatibility of the sleeves to examine the validity of the sleeve drafting method acquired using the regression equation. The test proved that the custom sleeve pattern and the general-purpose sleeve pattern were more suitable for the characteristics of arm structures. Thus, the new sleeve-cap part drafting method using the regression equation was shown to have validity. As a result, since a very significant correlation was obtained for the body measurement figures and the basic pattern of the adequate basic pattern of the sleeves, this study concludes that it is possible to come up with primary data that can be widely used by increasing the number of subjects.

This subject investigated visual evaluation of preference and fitness level of set-in sleeve in sleeve types(form)and studied suitable sleeve type at silhouette and targeted female students in twenties. The results of study were as follows: 1. Visual evaluation factors in set-in sleeve of sleeve types were selected 6 factors; the 1st factor is decorativeness, the 2nd factor is attractiveness, the 3rd factor was activeness, the 4th factor was feminine, the 5th factor was charming and 6th factor was a figural element. Decorativeness and attractiveness factors in visual evaluation of sleeve types were the most important level. 2. The visual evaluation differences of sleeve types in set-in sleeve were as follows; in the 1st factor, S and P2 were the most decorative sleeve type. in the 2nd factor, S, P2 and P3 are the most attractive sleeve type. in the 3rd factor, B and P3 were the most active sleeve type. in the 4th factor, L was the most feminine sleeve type. in the 5th factor, P1, L and P3 were charming sleeve type. in the 6th factor, P3 was evaluated that it shows narrowened shoulder sleeve types. 3.

Men's outer wear, such as jackets and coats appeared since the 16th century. They have been changed from doublets, coats, justaucorps, tail-coats, frock coats and morning coats to contemporary men's suits. Since the early 17th century, sleeve patterns of men's outer jackets had been mostly two-pieces close fitted patterns. The purpose of this article is to compare sleeve patterns of various jackets, which appear in various historic costume books. Armhole measurements, sleeve head measurements, amounts of ease, armhole depths, armhole widths, crown heights, sleeve width and sleeve angle had been compared to find out the differences among patterns of different times and styles. Coming to the present, the difference between top sleeve and under sleeve became more obvious, and the sleeve angle became less curvy. Another interesting point is that there had been considerable amounts of ease, which is the difference between sleeve head measurements and corresponding armhole measurements. It is because the sleeve has been attached to the armhole not by seam but by string. It is believed that the present sleeves have more natural curve and shape compared to the past.

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.

This study was conducted to reproduce the two-piece sleeve pattern of the ladies' jacket of the 1890's for Korean women of the twenties who have the standard body type and the average size. Fourteen two-piece sleeve patterns of the ladies 'jacket of the 1890's were collected and drawn to actual size. The length and width proportion of the upper-sleeve and under-sleeve pattern of the ladies' jacket of the 1890's were similar to the two-piece sleeve pattern of jacket which we see now. The elbow line of the two-piece sleeve pattern of the ladies' jacket of the 1890's was lower than the two-piece sleeve of jacket of today. The cap of the sleeve of the ladies' jacket of the 1890's was gathered and this gave volume to the upper part of sleeve but the lower part of the sleeve was tight. The study pattern of two-piece sleeve pattern which had the characteristics of the sleeve pattern of the ladies' jacket of the 1890's was designed like for Korean women of the twenties who have the standard body type and the average size through modifications based on the evaluation of dressing on two occasions. The study pattern was evaluated to have the silhouette of the sleeve of the ladies' jacket of the 1890's and to fit Korean women of the twenties who have the standard body type and the average size with the sensory test.
