Industrialization and modernization of the beginning of the IT industry is growing very fast. Since telecommunications industry was developed rapidly, technologies about miniaturization and high-precision of parts have been actively developed to lead information revolution. generally, the entire shear surface of the product applying fine blanking technology must be very precise. Fine blanking is used to save cost by avoiding post-processing of the product. When using press blanking, it spends a lot of money on the production by using many post-processing. Fine blanking typically used in 0.5~18 mm thick steel plate. Because a lot of post-processing cost can be used to process, except for fine blanking. In order to develop components "CHANCE CONTENTS" in the fine blanking process, the purpose of this study is to minimize the edge of the bridge, secured 95% of the material thickness of the shear surface using the 1.6 mm thickness of the material SPCC. Blanking process by introducing after changing thickness through forging process, due to change in vee-rring force and counter force, the experimental amount of depressions and flatness and the shear surface were analyzed.

본 논문에서는 희소 패리티 검사 행열로부터 생성된 생성행열을 사용하여 에러 정정능력과 높은 부호율을 갖는 DC-free 다중 모드 부호를 구성하기 위한 새로운 부호화 기법을 제안 한다. 제안된 기법은 별개의 후보 부호워드들을 생성하기 위해 고속 생성행열들을 이용한다. 복호 과정의 복잡도는 수신된 부호워드의 신드롬이 ‘0’인지 아닌지에 따라 결정된다. 만약 신드롬이 ‘0’ 인 경우 복호는 수신된 부호워드의 잉여 비트들을 삭제하여 간단히 수행되고, ‘1’인 경우에는 합곱 (sum-product) 알고리즘으로 복호가 이루어진다. 제안된 기법은 DC 성분을 억압하면서도 낮은 비트 오율을 가질 수 있다.

In this review quality improvement, new products and processing of ginseng are discussed. Ginseng products are generally classified into two types; the dried product without significant change in original shape of fresh ginseng and various processed ginseng products in liquid or solid types prepared by addition of either ginseng extract of ground powder. The dried ginsengs are generally made 4 years old fresh ginseng roots for production of white ginseng and 6 years old ones for red ginseng. The processed ginseng products, such as ginseng drinks, extracts, teas, powders, capsules or tablets are prepared by addition of extract or powder of the ginseng roots which contain relatively high amount of saponin. At present, more than 200 items of 40 types of products are commercially available in over 70 countries in the world, Since consummers preference on the quality of ginseng products as an health food differs with their cultural background of each country, new products development and quality improvement should be investigated with concerning the particular preference of the consummers of various country. It has been generally found that the Orientals has higher product acceptance on strong ginseng flavor while the Westerners generally prefers the products having mild ginseng odor and taste. Recently consummers are asking for supplemented type of ginseng products with various medical herbs and vital materials instead of ginseng alone. Therefore future work on product development should be emphasized to meet the consummers demand and preference.

This paper discusses the deformation characteristics of a scaled-down automotive outer door panel with vacuum-assisted incremental sheet forming. The vacuum condition between the die and Al6052-H32 sheet with a thickness of 1.0 mm is reviewed with the goal of improving the geometrical accuracy of the target product. The material flow according to the forming tool path, including the multi-tool path and conventional contour tool path, is investigated considering the degradation of the pillow effect. To reduce friction between the tool and the sheet during incremental forming, automotive engine oil (5W-30) is used as a lubricant, and the strain field on the surface of the formed product is analyzed using ARGUS. By comparing the geometry and material flow characteristics of products under different test conditions, it is confirmed that the product surface quality can be significantly improved when the vacuum condition is employed in conjunction with a multi-tool path strategy.

The study aims to determine the optimum sterilization rate and water activity of Chinese traditional smoke-cured bacon product (Larou) in the preservation with natural coating solution. With the response surface methodology (RSM), we analyzed 3 factors of processing conditions (the concentration of lysozyme, concentration of sodium alginate, and concentration of chitosan) and 2 response factors (sterilization rate and water activity). Sterilization rate and water activity of Larou were largely affected by the concentration of lysozyme, concentration of sodium alginate, and concentration of chitosan. The final optimum concentrations of lysozyme, sodium alginate, and chitosan were 0.09, 1.40, and 1.60% and realized the high sterilization rate. Water activity of sliced Larou was significantly correlated with the sterilization rate. Low-field nuclear magnetic resonance analysis verified the optimum processing conditions. The coating resulted in 99.69% rate of reducing bacteria after 30-day storage. The data of the total number of colony, peroxidation value, moisture content, pH, and sensory evaluation provided the theoretical basis for extending the shelf life of Chinese traditional smoke-cured bacon product (Larou) with natural coating solution.

All firms require new stimulus to spurt growth. Therefore it is necessary to successfully develop new products and to employ appropriate marketing practices for the new products to enter and settle in the market. Binggrae, a Korean company that specializes in dairy and processed dairy products, introduced a ready-to-drink (RTD) coffee product, 'a Café la' to expand its business into the coffee market in 2008. Binggrae was a latecomer in the RTD coffee market but a Café la has shown an impressive average sales growth rate of 115% as of 2011 since the launch. Moreover, it is a steady bestselling coffee brand among the Polyethylene terephthalate (PET)bottle category. Binggrae found potential and opportunity in the growing coffee market and made efforts to develop a new product that can be differentiated from the existing products. The result was PET bottle coffee, which was more portable and convenient to drink than coffee products offered in cups or cans. PET bottle coffee is produced through the patented Aseptic Filing System, thus the original coffee flavor stays fresh when combined with milk and has a longer shelf life than coffee products in cups. Moreover, as the taste of coffee consumers has become more sophisticated, Binggrae developed a premium product by differentiating the product processing method and by using higher-quality Arabica beans. After launching the new product, the company also employed a well-designed communication strategy. First, Binggrae was able to confirm the level of market demand and market potential for the product by employing BTL (Below the Line) marketing strategies through the consumers' word-of-mouth. Afterwards, the company invested its resources for a full-scale ATL (Above the Line) marketing campaign. Later a Café la's TV commercial effectively portrayed the product's characteristics, and succeeded in raising consumer awareness of the product. As a result, a Café la has become the bestselling brand in the PET bottle coffee market. The successful new product marketing strategy of Binggrae'sa Café la offers many valuable implications for companies planning to launch new products in the future.

This paper deals with a batch processor model in which the batch processing speed depends on the jobs assigned to the batch. Each job is completed by accomplishing its required job processing quantity which is calculated as job speed product processing time. Its speed is given as not the exact value but the range. Thus the batch sets are constructed by the jobs which hold the speed in common. And the batch sets are processed as soon as possible. We developed the model to described the problem situation and adopt the total tardiness as the decision criterion.

The actual status of production, management and export of 96 traditional food processing companies which supported by the government in Kyungpook province were investigated. Governmental support contributed to the increase of farmhouse income, employment and depreciation of agricultural products a bit, but it was supported mostly to unexperienced party. Technologies for food processing developed in institute and college were little. 42 percent of packaging design was developed by service commission, but the agency was very limited. Total export price in 1996 was 2.3 billion Won, but it was decreased in 1997. The responce to the prospect of traditional food processing work, 37.5 percent replied that this work can bring up as exportable product, but ambiguious response was a little. To settle a weakness of farming food processing work, the establishment of special marketing comapny was required and this company should accomplish marketing advertizing and exporting business.

It was investigated that curved aluminum products with 'ㄷ' section or with 'h' section could be bended during extrusion by the extru-bending process. In order to make bending at the exit section of die, the flow of billet inside die cavity was controlled by the shape of billet. As results of the analysis of $DEFORM^{™}-3D$, it was known that the bending phenomenon at the die exit can be happened by the asymmetric section of billet. And it was known by the experiment with plasticine or aluminum material that an symmetric product with 'c' channel section and the product with flanged 'h' section could be bended because of asymmetric shape of billet.
