This study develops a new brassiere for new silver women. A new brassiere design was developed for the silver generation based on apreliminary survey; subsequently, a wire and no-wire type of brassier were developed after a second fitting evaluation. The results were as follows. First, in terms of brassiere design, the cup shape was designed as mold type full cup, shoulder straps were designed as camisole type with cups, bias tape was designed for body correction in the side line and mash tape was designed for easy movement below the cups. On the other side ofthe cup shape was a pocketdesigned on a support pad forthe wire type and a support panel to serve as a wire in the no-wire type brassiere. Second, brassiere patterns were designed by referencing the educational H pattern. Thetotal length was elongated by 5cmto reduce pressure when wearing a brassiere and the height of the front center increased by 8cm for the stability of the front center of the brassiere. In addition, the side line was moved back by 3cm and the width of the brassiere wings was designed widely at 10.5cm. Third, a wearing test was conducted for the wire type and the no-wire type brassiere with comparison products, using a 7-point Likert scale. Appearance results and movement tests for the wire and no-wire type showed a higher score than comparison products.

This study analyzed the domestic patent trends of brassiere to provide fundamental data for promising technology. Relevant patents were searched by inputting the key words of "brassiere" and IPC code "A41C" on patent information search service of KIPRIS. A search for bras patents from 1985 to 2019 revealed 533 registered applications out of the total 744 listed. The IPC code with the highest portion (40%) was A41C3/00 (brassiere), followed by A41C3/14 (forming inserts, 21.6%), and A41C3/12 (component parts, 13.3%). To arrange the guidelines of the content of brassiere patents, we carried out a qualitative technology analysis on 744 patents, to extract 850 technology cases applied in patents. From the technological features of each case, main categories were classified into two parts (function and structure) and function was divided into 7 sub-categories that included physiological comfort, physical comfort, utility, healthcare, appearance, and economic value. As for the structure, cup showed the highest portion (37.9%), followed by pad (16.5%), and wings (13.2%). From the aspect of function, appearance showed the highest portion (30.8%), followed by usability (22.2%), physiological comfort (14.6%), physical comfort (14.6%), economic value (10.7%), and health care (7.4%).

The purpose of this study is to analyze dissatisfaction and size appropriateness of the women with big breast for design the high functional big size brassiere. The data were collected from 179 women(between the ages of 20 and 39) residing in Gwang-ju using a questionnaire to purchase, wearing comfort, dissatisfaction of the size, wire and the pad of the big size brassiere. The data were analyzed with Chi-square test, t-test and ANOVA using statistical program SPSS 12.0. The results of this research are as follows; 1) Seven-two-point-two percent of the women with big breast more than C cup size polled said they had difficulty in looking for the suitable size of the brassiere and they usually weared the smaller size than the their own size. As a result, they felt inconvenience for the discord with the nipples and lack of the shape revision. 2) According to the result of the correlation analysis, breast size and Rohrer's index showed low correlation. 3) After dividing all respondents for this research into categories of the group of more than C cup and less than B cup the differences in responses were compared. The dissatisfaction with brassier were 'discord of cup size', 'pain due to the wire' and 'unnatural breast shape' in the group of more than C cup, compared to 'discord of cup size' and 'deformation of the wire and pad' in the group of less than B cup.

This study helps in the production of brassieres suitable for female adults by researching the actual wearing conditions and purchasing status, satisfaction rate, and preferences of female college students in their early 20's. The collected data was analyzed by a SPSSWIN 13.0 Program and the results of the research are as follows. 1. There is a noticeable difference between the breast satisfaction rate and breast size, in addition the satisfactory rate was higher in the normal breast size or a little ample size than in the very small or very big size. According to the shape, the satisfactory rate for the breast appeared to be high in the case of the recognition and evaluation of the hemisphere type than the flat, cone, pop out, and downward type. 2. For fitness, the looseness at the top of the cup (pressed between the breasts at the upper part of the front middle), pressing and looseness at the upper sides of the cup, inappropriate size of the cup, tightness of the wings, tightness at the bottom round of the breasts, the narrow width of the wire, wide space of the shoulder strings, and the sliding of the shoulder strings had problems that needed improvement. 3. The major priorities for purchasing brassieres are size, fitness, and aesthetic qualities. As a result, the size and the fitness are more important than the trend or decorations since the brassiere has the function to support the breasts that shows that hygiene and sanitation are recognized as an important standard for undergarment selection. The size and the fitness are important factors regardless of breast types in the examination of the selection standards of the brassieres for each breast type, but the cone and hemisphere types have higher preferences for design; the pop out type has more considerations for the material of the cloth. The result show that appearance is more important for smaller breasts, but the functionality of the brassier is more important than the appearance for medium and larger breast sizes.

만곡근관에서 근관형성방법에 따른 근관작업장 변화를 평가하기 위하여 발거된 대구치의 협측 또는 근심 근관 40개에서 스테인레스-스틸 수동 파일 ($MANI^{(R)}$, 일본), 니켈-티타늄 수동 파일 (Naviflex $NT^{TM}$, 미국), ProFile, 또는 $ProTaper^{TM}$ (Dentsply-Maillefor, 스위스)를 사용하여 crown-down 방법으로 30번 크기까지 근관을 형성하고 근관형성 전후의 근관작업장 및 만곡도의 변화를 관찰하였다. 근단공에 대한 10-K파일 끝의 위치변화를 AutoCAD2000 (Autodesk 사, 미국)으로 측정하고 일원변량분석법 및 Tukey's studentized range test로 통계 분석하였다. 모든 군에서 근관형성후 근관장 및 만곡도가 유의하게 감소하였으며, 치관부 근관형성시 Gates Glidden bur를 사용한 수동파일 군이 ProFile 군보다 유의하게 많은 근관장 감소를 초래하였고, 치관부 및 근단부 전체 근관형성후에는 스테인레스 스틸 수동파일 군이 ProFile 군에서보다 유의하게 많은 근관장 감소를 나타내었다 (p<0.05).
