  • In order to study the degradation pattern of propanil in solution, the environmental factors such as temperature, pH and UV irradiation effect on propanil degradation were investigated. The degradation of propanil in solution was more rapid in high temperature than in low. The production amount of DCA was increased in high temperature, and then was decreased in a certain period of time because of conversion to TCAB, but the concentration of TCAB was maintained without more degradation. Propanil was rapidly hydrolyzed in alkaline solution as well as in strong acidic solution. Degradation product, DCA was rapidly produced and condensed to TCAB in strong acidic and alkaline condition. On exposur to ultraviolet light, 90% of original propanil was degraded within 20minutes, 0.3 ppm of DCA was produced in 10 minutes, and maintained the concentration throughout irradiation times.

  • Master packaging system consists of an inner individual package and secondary outer package. During the stages of chilled transport and distribution, the combination of primary individual package and secondary package was used to maintain a modified atmosphere for shiitake mushrooms. During the retail stage at higher temperature ($25^{\circ}C$), the primary individual package was exposed to display conditions after dismantling of the secondary packaging. The master packaging system was constructed to contain eight individual $30-{\mu}m$ thick polypropylene film bags of 500 g shiitake mushrooms inside a $40-{\mu}m$ low-density polyethylene bag. Carbon dioxide absorbent material [$Ca(OH)_2$] and/or moisture absorbent (superabsorbent polymer) were designed in their required amounts based on respiration characteristics and then applied to the outer secondary packaging in sachet form. Gas concentration of the packaging, temperature, and humidity were monitored throughout transport and storage. The quality of shiitake mushrooms was measured at the retail stage to determine the packaging effect. During the distribution stage of 108 h, $O_2$ and $CO_2$ concentrations in the master packaging system were maintained at 9~11% and 1~4% in the inner packaging, respectively, which are good for quality preservation. Compared to the control, the master packaging with $CO_2$ and/or moisture absorbents improved mushroom preservation and particularly reduced decay.

  • Mass production system of most manufacturing companies has been supplying us with various useful needs in life for many years. It leads our life to live in comfortable and prosperous circumstances. And we can consider that the contributions of the mass production system to the reduction of different stratification in community remarkable . However, The needs of many clients in these days are various, different, and segmented. It is undesirable to consider every Product on the same basis anymore. So these new requirements of the customers let manufacturing companies be ready for the new production systems which are able to satisfy all the customers, but differently. In this aspects, the customization system could meet new needs of the customers. As we know, cost increase and flexibility matter for the production are main difficulties for the introduction to mass customization. However, to make arrangements for the mass customization systems of the firms is an indispensible factor for maintaining competitiveness and coping with new needs in the future market. We should remember that customers' needs in market will be changing, segmenting, and diversifying, continuously. For this purpose this thesis is tried for studying strategical approach methods of the mass customization.

  • We examined American consumers' perceptions and attitudes toward edible insect-based pet food. In this study, 16 Americans in Korea who owned dogs were categorized into two groups, and focus-group discussions were conducted under three conditions. First, we observed the free association perception of edible insect-based pet food, and attitudes were analyzed after providing a newspaper article related to it. Finally, consumer attitude was examined in the context of purchasing. The study found that the participants had high awareness of the eco-friendliness of edible insects and showed a positive attitude toward news articles related to it. However, when it came to purchasing, they considered nutritional and health functional values compared to environmental values. Meanwhile, the rejection of insects was nevertheless the most important negative factor in pet food, as in general food. The results are significant in confirming the possibility of using insect-based pet food by examining the perceptions and attitudes toward the environmental, nutritional, and health functional values of edible insects under three conditions for American consumers.

  • Business environment is always full of challenges. Despite various strategic efforts, there are so many failure cases of misfit. With the weaker resource base and institutional foundation, startup firms find it more difficult to find the right spot in the stiff competition. In the middle of evolutionary process, the startup firms need proper strategies meeting the differential challenges along the multiple stages of growth. Following the idea of product life cycle, this study applies the four stages of growth-startup, initial growth, accelerated growth, matured, and decliing. The next step for the startup manager is meeting each stage of growth with proper strategic efforts, including strategy, structure, decision-making pattern, and control method. When the knowledge factor is introduced, there is a potential for higher performance. Based on the 'Detailed Survey on Startup Ventures in 2017,' this study explores the impact of the government subsidy program on the firm competitiveness and performance-along the four stages of growth. In each stage, the strategy factors showed differential impact.

  • This study analyzed various packaging materials and types for frozen foods and the effects of packaging materials on temperature changes during frozen process. Pouches with different film thickness were prepared and placed in an IQF freezer, then the temperature inside pouches measured using a deep thermometer. The most common types of primary packaging for frozen foods in the market was plastic pouches with polyethylene or polyamide/polyethylene multilayer materials. The temperature change inside of packaging was delayed with film thickness increased. As the size of packaged food increased, the temperature change inside the food was slowed down. In addition, the pouches with air inside took more time to reach $-30^{\circ}C$ compared to pouches with less air during frozen process. This study provides information on packaging materials and types for frozen foods and preliminary data of temperature change by different types of packaging.
