  • Eogeul-tang is a traditional Korean soup dish made from dried pollack, minced beef, and tofu. This comparative study analyzed the quality characteristics of Eogeul-tang by varying the added amounts of cow gristle. The objective of this study was to analyze Eogeul-tang to promote its functionality and increased consumer preference. Collagen contents were $18.08{\pm}0.13g$ and $22.17{\pm}0.14g$ per 100 g of dried pollack skin and knee cartilage of cow, respectively. The overall collagen content was higher in the knee cartilage of cow. Different amounts of cow gristle (25%, 50%, 75%, and 100%) were added to traditionally cooked Eogeul-tang, and the general composition of Eogeul-tang was analyzed. Significant differences were exhibited in the amounts of water content, crude protein, crude fat, and crude ash depending on the added amounts of cow gristle. Moreover, the collagen content also significantly increased as the amount of gristle content increased. In particular, significant increases in the amounts of collagen components, including proline, glycine, and alanine were observed with increasing amount of gristle. When a sensory test was conducted on Japanese, overall preference values were highest for Eogeul-tang composed of 25% beef and 75% gristle compared to traditionally cooked Eogeul-tang. In conclusion, the study results promote the functionality of collagen as well as the increased quality of Eogeul-tang added with cow gristle manufactured by traditional cooking methods.

  • To develop the tailor made rice flour products for consumers with increasing functionality of pine needles, rice cupcakes were prepared with adding different contents of pine needle powder (PP) and extract (PE, by pressing pine needle). The physicochemical, textural, sensory properties, and antioxidative activities of rice cupcakes were investigated. The antioxidative activities of rice cupcakes with PP and PE were higher than those of the control and were significantly different with adding pine needle type (PP or PE). The specific volume of rice cupcakes increased with adding PP and PE, except for 10 g PP added cupcake. Textural properties were also significantly different with pine needle types and contents. On the sensory preference test data, the scores of the teens, the twenties, and the thirties were higher in PP added rice cupcakes (3 and 5 g added), but those in the forties, the fifties, and above the sixties were higher in PE added rice cupcakes (3 g added). From these above results, the PP addition improved the processing quality of rice cupcakes (under 10 g added), but reduced unique flavor of pine needle. It was suggested that rice products added with pine needle would be developed to consider consumer's age, type of pine needle and its content.

  • The principal objective of this study was to assess the sensory and mechanical characteristics, moisture content and color values of Ogapisulggi by varying the quantity of Acanthopanax sessiliflorus Seemann var. Goma(Ogapi) berry powder and the types of sugar utilized. The moisture content, color values, texture characteristics, and sensory characteristics of the different Ogapisulggi were then measured and compared. When the quantity of the Ogapi berry powder was the same, Ogapisulggi with honey added and the equal amount of sugar and honey added group was moister than that with sugar. The ightness values and yellowness values were decreased with increasing the Ogapi berry powder, whereas the redness values was increased. In particular, decreased proportions were observed in the Ogapi berry powder and sugar-added group($R^2$=0.922), the equal amount of sugar and honey-added group($R^2$=0.922) and the honey-added group$R^2$=0.966). In our texture analysis, hardness and adhesiveness values were reduced in the 0.3% Ogapi berry powder-added group, and springiness, cohesiveness, and chewiness values were increased the Ogapi berry powder-added group. Sensory evaluation showed that the Ogapisulggi containing 0.3% Ogapi berry powder was the lowest in terms of color, flavor, after-swallowing and overall preference. On the basis of the results of this study, the best ratio of ingredients was as follows: 0.3% addition of Ogapi berry powder with sugar and 0.1% addition of Ogapi berry powder with honey, which supports the conclusion regarding the benefits of Ogapi berry powder supplementation in Ogapisulggi in terms of taste and functionality.

  • A RMON agent system, which locates on a subnet, collects the network traffic information for management by retrieving and analyzing all of the packets on the subnet. The RMON agent system can miss some packets due to the high packet analyzing overhead when the number of packets on the subnet is huge. In this paper, we have developed a light-weight RMON agent system that can handle a large amount of packets without packet loss. Our RMON agent system has also been designed such that its functionality can be added dynamically when needed. To demonstrate the dynamic reconfiguration capability of our RMON agent system, a simple port scanning attack detection module is added to the RMON agent system. We have also evaluated the performance of our RMON agent system on a large network that has a huge traffic. The test result has shown our RMON agent system can analyze the network packets without packet loss.

  • This study investigated changes in the quality and antioxidant activity of soy sauce with added Saccharina japonica powder (FSP). Soy sauce was prepared with acid-hydrolyzed soy sauce, brewed soy sauce, honey, ginger, garlic, dried red pepper, ${\gamma}$-aminobutyric acid (GABA)-enriched sea tangle fermented in lactic acid, and 1% or 3% S. japonica powder by soy sauce volume. The color, pH, microbiology, amino nitrogen, free amino acids, antioxidant activity, and sensory qualities of the soy sauce were evaluated. There were no significant differences in the general characteristics or antioxidant activity. However, the addition of FSP to the soy sauce enhanced the delicate flavor. Furthermore, soy sauce containing FSP had higher levels of GABA (50 mg/100 mL), a biofunctional ingredient. Therefore, the development of seasoning soy sauce with enhanced functionality seems possible.

  • The dairy industry, as part of the broader agricultural sector, is classified as a basic industry to the Korea economy. Basic industries provide income to a region by producing an output, purchasing production inputs, services and labor. An integrated, multidisciplinary approach for the next generation of dairy products with added health benefits represent the direct economic contribution. The commercialization of "nutritional" functional foods can only be successful if the consumer is confident in the scientific validity of the claims. Modern biotechnologies such as genomics, genetic expression and biomarkers of health performance suggested to whole dairy products, such as fluid milk, butter, cheese, ice cream and frozen dessert products (German, 1999). The following definition makes the point that dairy products can provide a nutritional value beyond the basic nutritional requirements: 1) The dairy industry has the opportunity to improve the health and well-being of its customers and/or to reduce their risk of disease through dairy products with added activities. 2) Functional dairy products are those that can be demonstrated to benefit target functions in the body in a way that improves the state of health and /or reduces the risk of disease. They are food products that are consumed as part of a normal diet rather than pills or supplements. 3) Dairy products based on functionality will need to link the scientific basis of such functionality to the communication of its benefit to the general public. 4) Both the efficacy and the safety of the food components with health benefits will require evidence based on the measurement of scientific biomarkers relevant to their biological responses and health end points. 5) Sound evidence from human studies based on intermediate health end points using accepted biomarkers will provide the basis for promotional messages divided into two categories-enhanced function and reduced risk of disease. 6) Success in solving key scientific and technological challenges will only be achieved by interdisciplinary research programs to exploit the scientific concepts in functional dairy science.

  • In order to develop a new traditional liquor by using Paecilomyces japonica, alcohol fermentation condition was investigated. Ethanol was produced maximally when 1% P. japoniea and 10% koji were added into mash and fermented by Saccharomyces cerevisiae at $25^{\circ}C$ for 15 days. Sensory evaluation and physiological functionalities of P. japonica traditional liquors made by different addition ($0.1{\sim}2.0%$) of the fungus were also determined and compared. As 0.1% P. japonica was added to mash, the liquor was best acceptable, and its fibrinolytic activity and nitrite scavenging activity were 11.2U and 19.8%, respectively.

  • As an investigation for utilization of squid viscera oil as a food source, we attempted to improve a quality of fish burger by addition of emulsion curd formed from gelatin, water and refined squid viscera oil. Judging from the results of peroxide value, brown pigment formation, color value of Hunter, jelly strength and sensory evaluation, the reasonable amount of emulsion curd for the improvement of a fish burger functionality was determined as 6% on the weight basis of the chopped mackerel meat. Total plate counts, volatile basic nitrogen and histamine contents in fish burger prepared by addition of 6% of emulsion curd were $6.2{\times}10^4\;CFU/g$, 19.0 mg/100 g, and 50.7 mg/100 g, respectively. It may be concluded, from the above results that the emulsion curd-added fish burger is a safe as a food commodity. The ratio of polyenes to saturates of emulsion curd-added mackerel burger was 1.13. By adding emulsion curd formed from gelatin, water and refined squid viscera oil, color in cross section, texture and lipid functionality of mackerel burger could be improved in part.

  • The protective activity of seolitae chungkukjang added with green tea against oxidative stress was investigated under the cellular systems using LLC-$PK_1$ cells. The treatment of 2,2'-azobis(2-aminopropane) dihydrochloride (AAPH) showed increase in lipid peroxidation, and decrease in endogenous antioxidant enzymes activity and cell viability. However, the methanol extract of seolitae chungkukjang inhibited lipid peroxidation by 58.3%, and increased cell viability up to more than 60%. In addition, it enhanced superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities. Seolitae chungkukjang improved oxidative stress-induced cellular injury through the radical scavenging activities. In particular, the addition of green tea in seolitae chungkukjang showed stronger effect against oxidative stress induced by AAPH. The more addition of green tea resulted in the greater antioxidative effect through elevation in activities of SOD and GSH-Px, and inhibition of lipid peroxidation, eventually leading to increase in cell viability. Theses results suggested that seolitae chungkukjang added with green tea have protective effects from cellular oxidative damage and could be considered as an application for the development of chungkukjang with functionality.

  • This study investigated the effect of apios powder on the quality characteristics of sausages. The results were as follows: pH values of the sausages were not significantly different among the samples. The amount of moisture content in the sausages decreased with increasing amount of apios powder. Increase in apios powder increased the lightness (L) value but decreased redness (a) and yellowness (b) values. Increase in apios powder increased the hardness and chewiness of sausage but decreased the adhesiveness. Apios powder had no significant effect on gumminess and springiness of the sausages among all samples. Total phenolic compound content and DPPH radical scavenging activity of apios powder added sausage significantly increased with increasing apios powder. Total bacterial counts of apios powder added sausage increased in all the samples as storage period passes and after 4 weeks of storage, the more adding ratio of apios powder was increased, the total bacterial count decreased. In view of above results, apios powder was considered to be food material suitable not only for functionality but also for developing sausage product of which preservation property is improved. From the results, 100% apios powder can be used to make optimum level for production of sausage.
