  • In this paper, we proposed the test equipment that can perform separate performance tests to mass-produce the Automatic Test Equipment. Until now, the performance test of the ATE has been performed after it has been assembled perfectly. It is possible to perform the performance test only when the external device manufacturing and setting of measurement resources and the internal wiring work have been completed. So we have been studying test equipment that separately tested the switching devices that played a key role in the performance of the ATE. To build the test equipment, we reviewed the circuit card assemblies that make up the switching devices. We designed a test equipment that satisfies the performance test and apply the completed test equipment to the actual production process to analyze whether it was effective in improving the time and workability of the performance test. The test equipment has the advantage that it can be used universally in the mass production process of ATE with the same type of switching device.

  • This study was conducted to mass-produce brown stock optimized by using a high-pressure heating extractor and to use brown stock as a material for developing various products. For these purposes, we attempted to produce standardized brown stock by extracting brown stock using a high-pressure heating extractor and compared it with brown stock extracted by the traditional method in terms of general elements and mechanical and sensory characteristics. With regard to how to prepare optimal brown stock, the best brown stock was that extracted seven times repeatedly by the traditional method, but the method had a large economic loss in terms of material consumption and took a long time in extraction. Thus, considering time and labor, it was concluded that extraction at 120$^{\circ}C$ for 15 hours using a high-pressure heating extractor is the optimal extraction condition in terms of economic efficiency and quality. The results of this study are expected to be useful as a practical material for making brown stock production process more convenient, applying cooks' traditional cooking techniques to mass production, maintaining standardized superior quality and taste, and improving shelf life.

  • The purpose of this study is to derive the future-oriented characteristics Sonia Delaunay presented at the time based on the identity and modernity shown in her works and diverse activity. The scope of study spans from 1907 to the start of World War II and includes both applied and fine arts, with a focus on textiles and fashion. The research method is a literary study that includes old documents, exhibition booklets, and explanations from museum curators. The visual materials are actual works observed at exhibitions and digital images of various exhibitions. As a result of the research, she was a practitioner who expressed her identity in marriage, artwork, textiles, and fashion. In order to embody her design and express modernity, she showed geometric and modern motifs and she incorporated a sense of bright color and modernized light into her work by following the principle of simultaneous contrast in color. Additionally, she applied Hungarian embroidery techniques to simple materials and created geometric abstraction with her simultaneous colors, which contributed to both originality and the mass production of textile design. The future-oriented characteristics she presented are the dynamism of modern rhythm, the expansion of convergence and collaboration, the innovation of new production and exhibition, the media of consumer society, and the femininity of modern life. She recognized the mass consumer society and mass production of the early 20th century and actively utilized various media and genres to evoke a dynamic sense necessary for modern life and presented a design to be seen as a modern woman.

  • The effects of dietary levels and feeding period of Korean hot pepper (Capsicum annum) seed on the performance and egg quality were investigated. Rhode Island Red layers of 84 wk of age were fed the experimental diets containing O.O(Control), 0.5, 1.0, 2.0, and 3.0% of HPS, respectively, in individual cages during 10 wk of the feeding period. The dietary hot pepper seed significantly(P<0.05) improved hen-day egg production and daily egg rnass, but reduced egg weight(P<0.05). During the 10 wk of the feeding period, the egg production and daily egg mass improved after 6 or 7 wk of feeding 0.5, 1.0 or 2.0% hot pepper seed diets. When the layers were fed the 3.0% HPS diet, it only took 1 wk to improve the egg production and daily egg mass. In addition, the birds fed 3.0% hot pepper seed diet showed relatively constant egg weight while those of the Control increased gradually as the feeding period passed. The dietary hot pepper seed significantly improved the eggshell thickness, and redness and whole color of egg yolk. The results indicate that dietary hot pepper seed( $\geq$2.0%) may improve the egg production and egg shell thickness, and increase the redness of egg yolk in layers.

  • In this study, we investigated the relationship between the morphology and the rheological properties of Penicillium citrinum to improve the production of neo-fructosyltransferase (neo-FTase). In a 2.5 L bioreactor culture of P. citrinum, it was observed that agitation speed and aeration rate had significant effects on the production of neo-FTase and that maximum cell mass and neo-FTase production obtained at 500 rpm and 1.5vvm were 8.14 g/L and $53.2{\times}10^{-3} U/mL$, respectively. Cell mass and neo-FTase production increased to 91.53 and 25.17%, respectively. In the morphology and rheology studies, P. citrinum showed a typical pellet morphology that was explained by a shaving mechanism; this phenomenon was significantly affected by carbon sources. The rheology of neo-FTase fermentation by P. citrinum was dependent on cell growth and fungal morphology.

  • A soybean-sprout rot epidemic occurred in a mass production soybean sprout factory in 2000 and 2001 in Korea, which caused up to 20% production loss. Among the causal pathogenic bacteria and fungi, Pythium deliense was found to be the dominant pathogen of severe root and hypocotyls rot, particularly in recirculating water system. An average of 90% of the isolated fungi from the rotted sprout on potato dextrose agar were Pythium sp. The fungal density of Pythium in the sampled water was monitored in the recycled water system for 1 year using a selective medium (com meal agar with Pimaricin, 10 mg; Rifampicin, 10 mg; and Ampicillin, 100 mg per 1 liter). The drained water from the soybean-sprout cultivation always had a certain amount of fungus in it. The removal of Pythium from the recycling water system must be thorough, safe, and environment friendly. However, the pathogen in the water was easily found even after ozone and chlorine treatments, which were devised on the recycling system for the removal of microorganisms. 5-$\mu\textrm{m}$ pore size filter was applied and was able to successfully control the disease. As the sprout industry increasingly shifts into mass production, the demand for water will increase continuously. Recycling water for sprout production is eco-friendly. However, a process must be devised to be able to first decompose organic matters before Pythium zoospores are filtered.

  • The purpose of this study is to determine the effects of production strategies operated by franchisors in the food service industry on the franchisees' culinary competence and subsequently franchisees' satisfaction with performance and recontract intention. In order to accomplish this purpose, two franchised enterprises which used mass-purchasing and mass-producing before distributing to each franchisee for the production strategies were participated and eventually 287 franchisees responded to this survey. Factor analysis and Cronbach's alpha showed the validity and internal consistency for the survey questionnaire. LISREL(8.72) was used to test the relationships between variables; production strategy, culinary competences, franchisee satisfaction, and recontract intention of the franchisees. The results present that the franchisees' satisfaction with the management system, quality of distribution, and quality of foods influenced on differentiation performance and supply performance of franchisees. On cost performance, only satisfaction with the food cost had an impact. The higher franchisee satisfaction with the franchisees' operations was, the higher recontract intention was in the franchise business. The results suggest the critical points for improving foodservice supplying system as well.
