The purpose of this study is to develop the applied brassiere pattern of women which are fitting for 75A. The constructing of this experimental brassiere were lower cup, upper cup, front panel and U-wing as well as a full cup embcing the entire breasts. Basing on the bra model from domestic experiment results, development of an applied design, round side type pattern, has been suggested. Thus, suggesting the round variation design bra, which is an applied design based on the basic model based on the breast volume. Based on the sizes that are in reference to Size Korea (2004) and related previous researches, the basic model that has been experimented with 11.4% polyurethane and 88.6% Nylon as the materials, has been selected as the model of research. This takes 75A, the size of which is set according to the underbust circumference and the breasts circumference, as the basic model. It is an application in terms of design, and there is no change to the cup volume or size because it has been moved only from the cutting line. The applied design changes the right side of the lower cup into an easily-movable form and attaches it to the upper cup, and the lower cup takes the right part of the upper cup to form a cup shape of round variation design. It also changes basic straight form of the wings, and alters them into U-shape.

In this paper, we propose that the calculation method for accurate wind speed using interpolation methods, and the finding method for accurate wind direction using interpolation polynomial, so we make better performance for 3-Cup Anemometer by the proposed methods. We embody the 3-Cup Anemometer with photo sensor to measure wind direction and wind speed. In order to more accurate wind speed and wind direction, we present the methods to overcome the limitations of system memory and of the sensor measurement error by 8 bit gray code (as substitute 360 degrees for 256 degrees data).

To provide the basic data to manufacture superior brassiere, this study was analyzed the evaluation of wear sensation of brassiere and the satisfaction of breast type by breast circumference and volume of 182 twenties-aged women. The results were as follows: First, it was reliable to set up the cup size of brassiere by using the breast circumference. Hemispherical breast was the same as cone-shaped breast in breast classification by breast circumference and volume. Second, the breast sizes were able to classify into under 200cc, 200~300cc, 300~400cc, and over 400cc by volume, but measuring the volume was more difficult than measuring the breast circumference. Last, there were correlations between breast circumference and breast volume by breast type. And there were differences on improvement, brassiere size, and the satisfaction of breast type by breast circumference and volume. This results will give basic informations for brassiere design that reflects breast type according to breast circumference and volume for functional brassiere.

This study was peformed to establish the standard size system to be required for the production of brassiere. The subject were 155 Korean twenties-aged women and were directly measured anthropometrically. From 27 measurements, 5 factors were extracted through factor analysis. The accumulative contribution ratio is 76.92％. Factor 1 indicates the degree of obesity around the chest, factor 2 is the drooping degree of breast, factor 3 is the contours and prominence, factor 4 is the breast breadth and breadth of bust point, factors 5 is the volume of breast. The subject were classified into 3 cluster as their breast types through cluster analysis. Type 1 is the closest to the ideal breast shape and not too droopy. This group belonged to 75A. Type 2 has small breast and belonged to 70AA group. Type 3 is the obesest and has the biggest and droopy breast. This group belonged to 75B. The distribution of size of brassiere had 3 sections from 70 to 80 showing a rate of 81.94% and the sin of the cup had 4 sections from AAA cup to B cup showing a rate of 89.70％. The production ratio of each brassiere size, it was found that the brassiere size of highest production ratio was 75A(16.39％) in type 1,70AA(16.27%) in type 2, and 75B(13.72％) in type 3. This suggests that it is necessary to adjust for the production rate of brassieres.

During a compression molding of continuous fiber reinforced composites, the separation of matrix and fiber is caused by the flow of the molding process. As the characteristics of the products are greatly dependent on the separation, it is very important to clarify the separation in relation to molding condition, degree of needle punching number on the degree of nonhomogeneity are studied.

Sometimes the problem occurs that a paper knob and a thread attached to a tea bag fall into tea water in pouring tea water into a conventional cup to extract bag type tea. A new cup was developed to solve that problem, which was formed with a thread groove(dia. ; about $1.5{\sim}2\;mm$, hight ; about $4{\sim}5\;mm$) in the upper end of the cup. As a result, the new cup with a thread groove is expected that a paper knob with a thread does not fall into tea water. In addition, the size of a paper knob and the length of a thread may be reduced 70%, respectively.

The purpose of this research is to find the fundamental data for the design and optimum operation condition for the disk atomization comparing the atomization characteristics of the modified straight vane type disk atomizer and the cup type atomizer widely used in the field of spray dry. First, the experimental comparison of the characteristics of $Na_2SO_4$ atomization has been carried out using the cup type disk atomizer and the three kinds of vane type atomization designed specially for the experiment. After the comparison of the experimental data of the $Na_2SO_4$ and raw milk have been conducted using vane type atomizer.

An inverse finite element approach is employed for more capability to design the optimum blank shape from the desired final shape with small amount of computation time and effort. In some drawing or stamping simulation with inverse method, it is difficult to apply inverse scheme due to the large aspect ratio or steep vertical angle of inclination. The reason is that initial guesses are hard to make out with present method for those cases. In this paper, a direct mesh marring scheme to generate initial guess on the sliding constraint surface described by finite element patches is suggested for one step inverse analysis to calculate initial blank shape. Radial type mapping is adopted for the simulation of rectangular cup drawing process with large aspect ratio and parallel type mapping for the simulation of S-Rail forming process with steep vertical angle of inclination.

In this work, vibration characteristics of high speed rotary bell cup for paint atomizer are numerically investigated. New type of bell cup model is proposed and additional corresponding models with design parameter variations for length and diameter are constructed. Dynamic characteristics, such as natural frequencies and corresponding mode shapes, are studied for each model as a first step. To investigate operation stability, critical speed of rotary bell cup is numerically analyzed based on Campbell diagram and separation margin between operating speed and critical speed is identified. Unbalance vibration responses are also investigated with respect to design parameter variation, operating speed and balancing quality grade of G. Then the proper design guideline for stable operation of high speed rotary bell cup for paint atomizer is suggested.

Characteristics of cell growth and heavymetal adsorption by recombinant Saccharomyus cerevisiae strains harboring multiple copies of the CUP1 gene encoding metallothione (MT) protein were studied in batch cultures. Recombinant S. cerevisiae strains harboring multiple copies of the CUP1 gene were superior to the host and wild-type yeast strains in terms of cell growth and heavy metal removal, indicating that the copy number of the CUP1 gene for MT expression played an important role in the adsorption of heavy metals. It was suggested that the CUP1 promoter for the MT expression is induced by manganese and zinc as well as copper An optimum copper concentration for MT expression and concomitant adsorption of heavy metals by recombinant S. cerevisiae was found to be 0.31 mM. A nonionic surfactant Triton X-100 enhanced cell growth by 17.7% and removal of zinc by 6.1% compared with the control case.
