  • In this study, the effect of probiotic supplementation on growth performance, blood metabolites, and meat quality of Hanwoo steer was investigated. A total of 32 Hanwoo steers (15-17 months, average body weight $462{\pm}37.9kg$) were randomly allotted to 4 dietary treatments (0, 0.5, 1.0, and 1.5% mixed probiotics), with four Hanwoo steers per pen (two replicates per treatments), and reared for 12 months. There were no differences among treatments in growth performance of Hanwoo steer (P>0.05); however, feed intake decreased linearly with increasing levels of mixed probiotics. Growth hormone and Blood Urea Nitrogen (BUN) levels responded linearly with increasing levels of dietary mixed probiotics (P<0.05), but not insulin and blood glucose did not. In particular, total cholesterol was significantly lower for the 1% mixed probiotic treatment in comparison with that of the other treatments (P<0.05). The pH, Thiobarbituric Acid Reactive Substances (TBARS), cooking loss, and meat color were influenced by increasing levels of mixed probiotics (P<0.05), but the carcass characteristics and shear force were not. Regarding sensory evaluation, the addition of mixed probiotics resulted in significant difference in meat color, tenderness, aroma, off-flavor, juiciness, and marbling score, but not in overall acceptability. In addition, fatty acid profiles indicated no differences between control and mixed probiotic treatments. In conclusion, mixed probiotic treatment at 1% levels can enhance consumer preferences possibly by reducing cholesterol and TBARS.

  • This article aims to identify the current status of outsourced production of Dongdaemun brands and to discover the consumers' perception of those outsourced products, their degree of satisfaction, and preference in purchasing those products. Moreover, the strengths and weaknesses of the outsourced products, as perceived by the consmers, have been identified, and specific methods and directions for efficient overseas outsourcing of Dongdaemun brands are suggested. This study also contains experimental works, in which I have prepared questionnaires, and my advisor have collected data. This survey was conducted on corporation managers, who directly operated clothing stores in Dongdaemun Market in December 2007. The collected data have been analyzed using SPSS 12.0 with various techniques such as t-test, paired t-test, frequency analysis and $X^2$-test. The results are summarized as the following: a) Comparison of the current outsourcing status of Dongdaemun brands showed that only eight out of the total 42 investigated companies have actually been outsourcing the production of their clothes. The biggest advantage of outsourcing was the reduced unit production cost, while low quality of products, delayed production, difficulty of control and management were shown as its disadvantages; b) the reason for purchasing clothes in Dongdaemun Market was to buy various clothing products. Comparing these reasons among different groups showed that there was a significant discrepancy in terms of trend design and copy design, in which wholesale consumers had shown a higher degree than retail consumers; c) and the preference for outsourced products of Dongdaemun brands was negative in both wholesale consumers (71.05%) and retail consumers (83.54%), as they both prefer clothes manufactured in Korea. Both groups selected the expensive price as the biggest disadvantage of Korean products, and picked design as the biggest strength of the outsourced clothes. Furthennore, both wholesale consumers (63.16%) and retail consumers (74.68%) selected Italy as the most preferred country for outsourcing clothing production. in which their reason had been their expectation for good product quality. The least preferred country for both wholesale (47.37%) and retail (50.63%) consumers was China, a country which they expected poor product quality.

  • This study was carried out to investigate the effects of various subsidiary ingredients added to Kimchi on the acceptance and sensory characteristics. In appearance acceptance, Kimchi without red pepper powder rated the worst, while samples without salt-fermented anchovy extracts, garlic, ginger, radish, green onion and onion showed no significant difference(p<0.05) compared with the control, and were all rated highly in acceptance. In flavor, taste and overall acceptance, the sample without garlic rated the worst, indicating that garlic has the greatest effect on the acceptance of Kimchi. Red pepper powder had an effect only on the pungency of Kimchi's flavor characteristics. Salt-fermented anchovy extracts enhanced umami taste, sweetness and saltiness of Kimchi. Garlic also enhanced the general flavor such as sourness, umami taste, sweetness, carbonated flavor and fresh flavor, but inhibited the moldy flavor. Ginger had effects on pungency, fresh flavor of Kimchi, while radish, green onion and onion only had an effect on the fresh flavor of Kimchi. Garlic had significant effects on the moldy flavor and bitterness of Kimchi's sensory characteristics, and the amount of garlic added to Kimchi influenced the sourness, sweetness and fresh flavor, irrespective of the kinds of Kimchi and fermentation temperature.

  • In this paper, we propose a dynamic power management framework for multi-core systems. We reduced the power consumption of multi-core processors such as Intel Centrino Duo and ARM11 MPCore, which have been used at the consumer electronics and personal computer market. Each processor uses a different technique to save its power usage, but there is no embedded multi-core processor which has a precise power control mechanism such as dynamic voltage scaling technique. The proposed dynamic power management framework is suitable for smart phones which have an operating system to provide multi-processing capability. Basically, our framework follows an intuitive idea that reducing the power consumption of idle cores is the most effective way to save the overall power consumption of a multi-core processor. We could minimize the energy consumption used by idle cores with application-targeted policies that reflect the characteristics of active workloads. We defined some properties of an application to analyze the performance requirement in real time and automated the management process to verify the result quickly. We tested the proposed framework with popular processors such as Intel Centrino Duo and ARM11 MPCore, and were able to find that our framework dynamically reduced the power consumption of multi-core processors and satisfied the performance requirement of each program.
