The purpose of this study was to get basic information about aspect of consumption, production, and hygiene of the brassiere, which should be mentioned. As the research methods, 2172 women who are living in Pusan, Korea were selected and were classified according to age, job, and marriage. In the data analysis, percentage, average, standard deviation, Chi square($x^2$)-test were used. The results of analyzing data in this study are followed; 1. The mean age of first time wearing of brassiere is 14.1 years and the mean number of having brassiere is five. 2. For the anterior shape of brassiere, the wire type is extremely weared. The type that does not to want to wear is plunging type and most favorable type of brassiere is support type. 3. For the posterior shape of brassiere, extremely weared types are standard and straight type. Round type II is that does not to want to wear. 4. It is all type that showed statistical significance for age, job and marrige.

In recent years, hydrologists have been interested in the radial spectrum and its estimation in two dimensional storm field to construct simulation model of the rainfall. This paper deals with the problem of transformation from the spectrum or isotropic covariance function to two dimensional random field. The extended turning band method for the generation of random field is applied to the problem using the line generation method of one dimensional stochastic process by G.Matheron. Examples of this generation is chosen in the random components of the multidimensional rainfall model suggested by Bras and are given with a comparison between theoretical and sample statistics. In this numerical experiments it is observed that first and second order statistics can be conserved. Also the example of moving storm simulation through Bras model is presented with the appropriate parameters and sample size.

Underlying dress forms for high coverage patterns are very important in the dress industry. Size 9 from brand D was chosen according to the analysis that it was the best option because a dress should have a large allowable range in one size. The criteria for selection were the dress form with a waist circumference of 63.50 centimeters, which is close to the standard size of women in Korea. Brassieres for dresses were included to enhance the aesthetic value of the correction process in producing a basic dress pattern. An experimental torso pattern was applied to evaluate the fit and suitability of the dress form that was also later verified in the process of the dress works. Three dresses were produced and presented on the chosen study dress form. The research procedures are as follows. First, the sell-through rates and feedbacks were collected from the dress form vendor. Second, a literature survey on dresses and a dress company investigation were conducted. Third, the amount of body dimension changes due to the use of a bra in the dresses were examined. Fourth, after the correction of the dress form, the torso pattern was made by draping. Fifth, the torso experimental clothing made of muslin material was evaluated. Sixth, the dress works of the top design were presented using the size 9 basic pattern developed by brand D.

A planetary gear assembly is a key component to combine and/or split a power from the source. With a planetary gear assembly, a continuously variable unit extends its capacity by means of power bra nching mechanism. Power branching with one planetary gear assembly and one continuously variable unit is categorized into 12 basic types. Each type represents peculiar power transmitting characteristics. Additionally, a multi-mode (range) continuously variable transmission can be designed with accompanying clutches. A multi-mode continuously variable transmission changes the path through which the source power is transmitted. Each path has its own features, such as high efficiency. In this paper, some design principles are examined such as, criteria to guarantee the minimum power efficiency, and constraints to guarantee the smooth mode shift after discussing well-known features of multi-mode M mathematically.

We check up on whether the one-dimensional station precipitation model of Geogakakos and Bras is suitable to the storm model for Chonju station or not. The fundamental variables of the physically based model consists of the pressure at the cloud top, the hight-averaged updraft velocity(HAUV), and the inverse of the average diameter of the hydrometeors(ADH) at cloud base. And they are parameterized by input variables. The parameters are eastimated by the direct search algorithm of Hooke and Jeeves in this paper. The results show that HAUV and ADH are dominant factors to minimize root mean square error between the calculated and the observed rainfall. In this numerical analysis, the deviation between the calculated and the total observed rainfall is small, otherwise the gap for the time distribution is quite big.

This study has as its primary aims the following: to create a fashion design based on the aesthetic value of Art Nouveau which flourished from the end of 19 century to the beginning of 20 century. In this thesis, two themes, Rose Aroma and Iris Memory are selected among the flower patterns and are used to create two works. First, the Rose Aroma theme is for an evening dress of S-curve style made with Silk Jacquard based on rose image of Art Nouveau. For decoration, artificial rose and its stem, and leaves are used to highlight hip line. By such design associated with a flower garden, cubic effects are expressed as a design point. Second, the Iris Memory theme is for a wedding dress made with tulle based on Iris image of Art Nouveau. This dress has a special point in its top bra, underwear used like an outer garment, involving spangle, beads, pearl, and cubic in order to enhance its visual effect. These works are significant in presenting the development possibilities of various fashion designs by introducing Art Nouveau style into diverse modern fashions.

We have numerically analysed the effects of the light sourer spectral power distortion in an optical CDMA system using PN codes and FBGI for ultra-fast multi-access optical networks. The interference between two CDMA channels decreases with an increase in the code length and the .simultaneous access number is equal to the code length in the region of 0 to 15% spectral power distortion. As a result, the spectral power distortion with optical spectrum is very important in designing the optical CDMA systems.

This study investigates the breast cathexis and brassiere design preferences of Chinese citizens living in Hong Kong in order to provide marketing intelligence for bra manufacturers whose target customers are from this group of potential customers. A questionnaire composed of questions concerning breast shape evaluations, brassiere design preferences, and brassiere purchase and wear practices was administered to 165 Hong Kong Chinese female undergraduates(N=165). For an analysis of our data, we used the SPSS program(version 14.0). The results indicate that a majority of Hong Kong Chinese female undergraduates perceive their breasts as 'slightly smaller than normal' (n=59, 35.8%) or 'normal'(n=78, 47.3%) in volume, and 'conical'(n=77, 46.7%) or 'flat'(n=46, 27.9%). The results also suggest that Hong Kong Chinese women possess positive breast cathexis, with only a third of the respondents reporting dissatisfaction with their breasts. Women with dome-shaped breasts expressed the most positive breast cathexis, followed by those with cone-shaped breasts. The results also show that Hong Kong Chinese typically purchase 2 brassieres per year, which is a lower purchasing rate than their counterparts in Korea(Cha & Sohn, 2010) and Taiwan(ICT Life Style Research Center, 2004). The findings also demonstrate that the preferred brassiere color is black(57%), unlike in Korea, where women prefer skin-colored brassieres.
