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.

The purpose of this study is to develop the basic patterns of adult womens brassiere therewith, provide for some basic data useful to the brassiere manufacturing which are both functional and fitting. For this purpose, 220 adults women(aged between 20 and 59) were sampled to be measured for their body sizes and tested for their brassiere wearing. The collected data were statistically processed using the SAS 6.12 for Means, Standard Deviation, etc. The results of this study can be summarized as follows; 1. In order to develop the basic patterns of adult womens brassieres, 75A size was selected out of 12 size combination(3 women per 75A size) and then, their brassiere fitting was tested. As a result, the fronts of the basic patterns were found to have such problems as undone front center, poor levelling of upper cups bottom line or lower cups top line, poor shape of upper cups outside top line and shoulder strip position. On the other hand, n the rear side of the basic patterns, the central part of the wing was slightly lifted, while the wing width and straps interval did not befit the full-cup brassiere. The result of this first brassiere fitting test showed that the functionality and aesthetics of the basic pattern brassieres were more or less satisfactory, and thus, the problems were address for the second test. In the second test, the aesthetics, breast-shaping effect and functionality of the basic pattern brassieres were much improved. 2. The basic patterns of adult womens brassieres were characterized by a round cup wired as well as a full cup embracing the entire breasts. Each basic pattern which consisted of upper and lower cups was shaped \"straight(-)\". The basic sizes adopted at the first design stage (see fig. 1-2) was 75A of which was designed as upper foundation basic pattern. At the second stage, the upper body foundation pattern were used to design lower cup, upper cup, front panel and wing in their order.(see fig. 3-5, fig. 8)5, fig. 8)

본 연구는 로봇착유기 개발을 위한 기초연구로서 유두위치 측정장치와 로봇제어 시스템을 구성하고 그 성능을 분석하고자 수행되었으며 그 결과는 다음과 같다. 1. 유두인식은 스테레오 측량법에 기초한 이미지 장치로 처리했으며 유두인식오차는 (x, y, z) = (0.83, 1.95, 0.81)mm이다. RCS로 좌표값을 변환했을 때 시스템 전체의 오차는 x = 0.9mm, y = 2.0mm, z = 0.9mm였다. 2. 로봇 유두컵 착탈 시스템의 로봇 착탈 성공률은 평균 91.5%로 나타났다. 작업시간은 27.8sec였으며, 이미지 처리를 포함한 전체 작업시간은 86.1sec로 나타났다.

Cup drawing tests were performed to evaluate the friction characteristics of sheet metals. The linear relationship between drawing force and blank holding force obtained from the cup drawing test was used to calculate the coefficient of friction of the sheet metal. The friction coefficient was compared to that from conventional draw bead friction test. It was clarified that the cup drawing test can be used as a simple and convenient method for evaluating the friction characteristic of the sheet metal and also lubricity of the lubricant used.

I Study on the security measures of the World Cup Korea and Japan jointly in 2002. The paper, purporting to consider security counterplans, comprise five chapters. Chapter I which sets out purpose, scope and method, is followed by chapter II, dealing largely with the legislations and importance on the security measures of the 17th FIFA World Cup in 2002. Chapter III concerns the security environment -internal environment, external environment- and the highlights accidents and events of history on the FIFA World Cup. Chapter IV consider security measures of the World Cup Korea in 2002. It is followed by concluding observation made in chapter V. To be operated security systems effectively, these need to be regulated according to a security measures organizations, security facilities and equipments, security plan and protective force, security operations and so forth.

A systematic investigation for process design in deep drawing is necessary for quality improvement of drawn cups. This study has been concentrated mainly on the influence of process design scheme on product qualities in cylindrical cup drawing. Three types of process design scheme were chosen in this study. That is, Case 1 is to finish drawing a cup of 50m in diameter in one stage, Case 2 and Case 3 are redrawing the drawn cups of 55, 65 mm in diameter to the final size respectively. Though experiments the maximum drawing force in two-stage cup drawing could be reduced up to 35% as compared with that of one-stage cup drawing. In addition, the Case 2 and Case 3 processes showed better product qualities than the Case 1 process when comparing distributions of thickness, hardness, dimensional accuracy.

There are many different kinds of forming processes to make a tubular product such as hydroforming and tube drawing. However, we should consider a better forming process in view point of energy consumption and $CO_2$ emission to save our earth. In this paper we have conducted FEM simulations to the various forming processes for sheet and tubular products to compare their energy consumptions. One example is tubular product and the other for drawn cup. From the comparisons of total energy for hydrofroming and tube sinking processes, hydroforming is consumed more energy than tube drawing. Also the cup drawing from sheet metal and tube sinking for the cup with flange indicate that the tube sinking is better than cup drawing of sheet metal in energy consumption.

Purpose: Mastectomy is one of the operative procedures of female to male transsexuals. It is aimed to excise all of breast tissues and to reconstruct male chest wall, areola, and nipple. Breast sizes are varied by developmental status and their hormonal therapy. There are several approaches for mastectomy. This study is aimed to suggest appropriate mastectomy methods according to breast size in the female to male transgenders. Methods: We retrospectively analysed 46 patients of female to male transgenders. Breast size was categorized by their inner wear size. In A cup size, mastectomy was done with periareolar approach. In C cup size, inframammary fold approach subcutaneous mastectomy was performed. In B cup size, periareolar approach was used for grade A or B ptosis patient, and inframammary fold approach was choosen for the patient with grade C ptosis. Results: Subcutaneous mastectomy was done through semicircular periareolar approach for 26 patients. There were 2 cases of major complications that should be corrected by hematoma evacuation. Circumareolar approach was used for 5 patients, and a case of nipple-areolar complex necrosis was observed. Two cases of another complications which were irregularity of breast and wound disruption could be corrected. Inframammary fold approach was selected for 15 patients. There was a case of wound disruption, so revision surgery whould be done. Four cases of breast irregularity was corrected spontaneously, and 2 cases of partial necrosis of nipple-areolar complex were corrected with secondary healing. Patient satisfaction score for periareolar, cicumareolar, and inframmammary fold approach were 4.5, 4.2 and 4.1, respectively. Some major and minor complications were observed, but satisfactory results could be secured. Conclusion: Semicircular periareolar incision looked adequate for A cup size patient, circumareolar incision was suitable for B cup size with grade A or B ptosis. In B cup size with grade C ptosis patient and C cup patients, inframammary fold incision looked suitable for optimal results.
