This study attempted to examine the effect on sensory characteristics and physiochemical properties of Grape jelly in various volume of adding carrageenan. The pH of Grape extract was 3.98. The viscosity was increased and the turbidity was decreased according to the increase concentration Grape jelly. The sensory evaluation of Grape jelly was the best with the ratio 0.5% carrageenan. The sensory evaluation of Grape jelly mold salad showed that the most preferable jelly was the one made by 0.9% carrageenan and 40% fruits(apple, orange and sweet persimmons).

Mold making and product manufacturing process was made by a die through a number of stages. Thereby, it takes a long period of time from the manufacture of mold until passed the products to consumers. However, it is not possible to meet the diverse desires purchasing of consumer. We made a 3D CAD Model aligned with product scan data using reverse engineering. Utilizing thereafter flow analysis to derive the optimal mold conditions, by applying the condition, and devised a mold fabrication process that is much shorter than the conventional process for fabricating a mold. In this study, the outlet cover to the product, it describes a process, as a result, it was confirmed that the number of steps can be shortened much more than the conventional process.

The purpose of this study is to offer basic data for designing and making of brassiere with the consideration of the physiological nature of man. Each of 3/4-cup wired upward-support-type Mold Bra of 75 size with basic pad made at three representative domestic companies (A, B and C Company) was selected for analysis of pattern and components. The following is the result of this study. 1. That Company A's bra had the highest cup, relatively narrow width, the widest front-center and the highest front center at front pad. That of Company B had relatively short wing over the base and much difference at the height of cup depending on the presence of wire. That of Company C had low and wide cup, the widest bust span and the front center width, the front center height of front pad, the base length of front pad and the length of wings were observed to be of the figures between those of Company A and B. 2. The Bra of Company A had the biggest front center angle of $6^{\circ}$, while that of Company C had the biggest wing angle of $18^{\circ}$. The Bra of Company B showed the biggest difference of patterns depending on the presence of wire. Those of Company A and C showed very similar shape when wire was inserted. 3. The order of making brassiere is following: making of exterior mold cup${\rightarrow}$ sewing exterior cup and circumference of mold${\rightarrow}$ sewing base and wings${\rightarrow}$ sewing binding tape to base${\rightarrow}$ sewing cup and main pad${\rightarrow}$ sewing binding tape to upper sides and upper part of wings${\rightarrow}$ sewing wire-tape to interior base of cup${\rightarrow}$ inserting of wire inside wire-tape${\rightarrow}$ sewing hook & eye on the back of wings${\rightarrow}$ sewing shoulder string.

The target of this study is development of web based mold discrimination system by matching vision information with CAD database. The use of 2D vision image makes possible speedy mold discrimination from many databases. The image processing such as preprocessing, cleaning is done for obtaining vivid image with object information. The web-based system is a program which runs to exchange messages between a server and a client by making of ActiveX control and the result of mold discrimination is shown on web-browser. For effective feature classification and extraction, signature method is used to make sensible information from 2D data. As a result, the possibility of proposed system is shown as matching feature information from vision image with CAD database samples.

Free-form Concrete Panel(FCP) is each panel that composes the concrete exterior skin of Free-form building. FCPs contain curved surfaces, and FCPs have different curvature, size, and angles. In order to manufacture FCP, high technology is required, and it is currently difficult to manufacture it according to the design shape. In particular, many errors occur in the side shape of FCP. This is because when the side silicone mold is applied, it is installed without a coupling method between molds and support device. In this study, basic research was conducted to develop a side silicone mold support device to solve the above problems. We classified the required performance and derived the detailed requirements. Also, Based on this, we drew the basic design of the support device. We plans to conduct design improvement, mock-up making, and FCP manufacturing experiments through future research.

The urethane based on prototype mold is very useful for making prototype. Especially, the method of stereolithography mold was turned out to be rapid and accurate 3-dimensional modeling data. Urethane resin (TSR-755) has heat resistant and is good for make hundreds of prototypes. In this study, we compared with various designed cooling channel and analyzed of cooling effect and deformation using commercial code Simpoe-Mold for injection mold. As a result, efficiently arranged cooling channel could make 19% of shrinkage to reduce and 46% cooling time to reduce.

RP&M (Rapid Prototyping and Manufacturing) is the most appropriate technology for the small-lot production system, because the production cycle is getting shorter owing to various needs of the consumer. In this paper, rapid tooling technology is applied to the casting process. The casting process has the ability to reflect complicated shapes in one process. But it has not been widely used to make a die and mold because of the poor surface quality caused by air bubbles on the surface of the casting product. In this study, the porous casting mold is fabricated from a mixture of plaster and water-soluble binder. The porous casting mold can improve the characteristics of casting products with the help of the vacuum sealed casting process. The vacuum sealed casting process is an advanced technology that removes the air bubbles between the porous casting mould and the liquid metal, thus making the surface of the casting product finer. The purpose of this paper is to develop a high quality shoe mold using porous casting mold and to apply the RP&M technology to the shoe industry.

A study on machining electrode for LEO(Light Emitted Diode) mold with shaped end-mill is presented. The electrode machining by shaped end-mill has been used for maximizing the productivity in manufacture of semiconductor mold. However, it has not been researched systematically for many difficulties such as the making of shaped end-mill, generation of tool path due to distinctive tool geometry, and so on. Tool path is generated on the shaped end-mill geometry and cutting force to provide accurate and efficient machining of electrode. The verification program can drive enhancement of productivity, selecting cutting conditions from experiment function of cutting force. Also, compensation of tooting and machina error can make the electrode accurate by modifying tool path. Therefore, the research on machining with shaped end-mill can contribute to enhancement of accuracy and productivity in building semiconductor mold.
