  • The purpose of this study was to assess red beet as a natural colorant in emulsified pork sausage and to investigate the effect of red beet on quality characteristics of emulsified pork sausage during 20 d of cold storage. Red beet was prepared as a powder and a substitute with sodium nitrite at 0.5% and 1.0% levels in emulsified pork sausage. Red beet significantly increased the moisture content and pH (p<0.0001) and affected color traits. Lightness of emulsified pork sausage decreased by the addition of red beet powder (p<0.01), whereas lightness with red beet treatments slightly increased during 20 d of cold storage at $4^{\circ}C$ (p<0.05). Redness dramatically increased with red beet powder (p<0.0001). Color by sensory evaluation also showed a significant effect from red beet addition (p<0.05), whereas the other sensory properties such as flavor, tenderness, juiciness, and overall acceptability were not affected by the addition of red beet powder (p>0.05). Texture and 2-thiobabituric acid reactive substance were also not affected by red beet addition (p>0.05). Therefore, red beet could be a good natural colorant in emulsified pork sausage but it needs additional processing, such as betalain concentration and extraction as a juice, to be used as an antioxidant in meat products.

  • PURPOSES : Before-and-after studies of red light cameras were conducted with the aim of reducing the number of side right-angle collisions. Three different methods were used for the before-and-after studies, and the analysis results were compared. METHODS : This research used the naive before-and-after method, the comparison-group method, and the empirical Bayes method to study the effects of red light cameras on side-angle collisions. The results of the three before-and-after methods were compared and interpreted in terms of safety indications at signalized intersections. RESULTS : The research results showed that side right-angle collisions can be reduced by installing red light cameras at signalized intersections. All three methods guarantee safety improvements of 25~30% on average. With regard to the results of each method, the naive before-and-after method, the comparison-group method, and the empirical Bayes method showed safety improvements of 25.6%, 27.8%, and 29.7%, respectively. CONCLUSIONS : It was concluded that red light cameras are an effective countermeasure to improve intersection safety. In particular, by installing red light cameras, side right-angle collisions can be reduced by up to approximately 25~30%.

  • Meat products have become prevalent in people's diet, and sausages, with the Korean diet getting more westernized in modern times. In particular, emerged as one of the favorite and the most consumed food products in Korea. In order to attain the best recipe to maximize the sausage's sensual taste, we have attempted to experiment and to analyze the differences in characteristic tastes of the sausages with varying increments of crushed red pepper of 0%, 2.5%, 5,%, 7.5%, and 10%. The followings are our findings from our experiment. As the result shows that red pepper, instead of nitrite, added sausage has twice more red chromaticity than those not added, sausage can be colored in red solely with natural materials when sold in the market. pH and moisture decreased as more red pepper was added, it did not show large difference. Texture results showed that the original sausage became harder and its viscosity decreased as more red pepper was added. Cohesion appeared to be similar and red pepper added sausage was munchier and more flexible. In the results of sensory test, 5% of red pepper added sausage showed the highest score but did not have any significant difference. For each items, red pepper added sausage got higher scores and by supplementing it would be seen as a useful additive in developing natural color sausages.

  • In this paper, we analyze web response time depending on queue managements and transmission latencies in highly congested network situation. Under FIFO scheme, the response times are for three different sizes of queue are almost the same, but the response time increases as traffic intensity increases. The performance between different queue sizes shows more different in 90% and 98% traffic intensity than in 80% traffic intensity. Especially the difference becomes bigger in short latency case than long latency case. Under RED scheme, three differently tunned RED schemes do not impact on the response time when the size of queue is relatively large. When the queue size becomes smaller, the response time of the differently tunned RED schemes becomes different for short latency case while the response times are almost same for long latency case. When comparing FIFO and RED schemes under same size of queue, RED scheme shows less response time than that of FIFO for the long latency case in high traffic intensity.

  • The beneficial effects of digested onion extracts have been assessed by antimutagenic and anticancer activities by Ames test and SRB test. The total phenolic acids and flavonoids in onion extracts were determined. Red and yellow onions contain more phenolic acids and flavonoids than those in the white onion. Digested, extracts showed antimutagenic activity and anticancer activity, and it appears that the antimutagenic activity of digested extracts of onion against mutagens and anticancer activities were related to their phenols and flavonoids contents. Moreover, the extracts inhibited the proliferation of four human tumorigenic cell lines such as HT-29 (colon), MCF-7 (breast), DU-145 (prostate) and HepG2 (liver), in a dose-dependent manner. Phenolic acids and flavonoids caused oxidative damage to the cancer cell lines and induced apoptosis. Generally, red onion extracts showed effective antimutagenic and anticancer activity, and the digested red onion extracts elicited stronger antimutagenic activity than those of the onion extracts without digestion.

  • Background: We examined changes in red ginseng components after different doses of irradiation were applied. We also evaluated what housewives and teachers know about irradiated food, as well as their perceptions of and attitudes toward it. Materials and Methods: General nutrients and unique components of irradiated ginseng were then analyzed. Education on irradiated foods and red ginseng was provided to teachers and housewives on two occasions, and changes in their behaviors were evaluated via a qualitative survey. Results and Discussion: The ideal radiation dose to reduce the number of bacteria without changing the unique components of red ginseng is 7.5 kGy. Notably, after educational seminars on this topic, consumers' knowledge, attitudes toward, and perceptions of irradiated ginseng compared to non-irradiated red ginseng changed significantly. Conclusion: It is necessary to provide consumers with information on irradiated foods to promote the growth of the domestic food industry, and to improve public knowledge of the safety and effects associated with the irradiation of food.

  • To prepare diketopyrrolopyrrole (DPP) red 254 pigment with high shield and bright color, DPP red 254 crude previously synthesized was treated at various thermal-treat temperature, addition derivative and ball-milling. The properties of samples were measured by the means of FT-IR, UV-Vis spectroscopy, TEM, PSA, BET surface area analyzer, viscometer and spectrophotometer. It was found that solvent thermal-treatment of the sample prepared after ball-milling as nano-scale was very effective method in pigmentation process.

  • This study investigated the anti-oxidation activities of fresh Codonopsis lanceolata Traut (Benth et Hook) and red beans, and also the quality properties of fresh Codonopsis lanceolata Yanggaeng to which raw Codonopsis lanceolata Traut (Benth et Hook) was added. The DPPH free radical scavenging activities of fresh Codonopsis lanceolata Traut (Benth et Hook) and red beans were 31.42% and 37.98%, respectively. Thus, that of red beans was rather the total polyphenol contents of fresh Codonopsis lanceolata Traut (Benth et Hook) and red beans were 5.74 mg/g and 4.14 mg/g respectively, and the total flavonoid contents of fresh Codonopsis lanceolata Traut (Benth et Hook) and red beans were 5.07 mg/g and 1.29 mg/g respectively. As higher amounts of Codonopsis lanceolata Traut (Benth et Hook) were added to Yanggaeng, the water content in the Yanggaeng continued to increase. Preferences were in the following order: 21%>12%>28%>7%>0%, and it was found that the optimal level for addition of fresh Codonopsis lanceolata Traut (Benth et Hook) was between 12% and 21%. It was also shown that adjusting the amount of ingredients or agar would improve the product quality.
