This study was carried out to compare the meat quality of beef from Hanwoo supplemented with dietary Rhus verniciflua Stokes (RVS) meal, silicate (Si), and chromium-methionine (Cr-Met) during refrigerated storage. The 26 mon-aged Hanwoo steers were fed basal diets containing 4% RVS, 4% RVS+400 ppm Cr-Met, 1.4% $SiO_2$, or 0.14% $SiO_2+400 ppm$ Cr-Met for 4 mon prior to slaughter. The M. longissimus from carcasses were then stored at $4{\pm}0.2^{\circ}C$ for 7 d. The crude fat content was higher in the Si and Si+Cr-Met groups (p<0.05). The water-holding capacity (WHC) and tenderness were highest in the Si+Cr-Met group (p<0.05). With regard to fatty acids, the polyunsaturated fatty acid (PUFA) content was lower in the Si and Si+Cr-Met groups (p<0.05), and the monounsaturated fatty acid (MUFA) content was lowest in the Si+Cr-Met group (p<0.05). The TBARS and MetMb contents were decreased in the Si, Si+Cr-Met, and RVS+Cr-Met groups. Regarding meat color during storage, the Si+Cr-Met group showed the highest L, a, b, C values and total color, and those of the Si and RVS+Cr-Met groups were higher than the RVS group (p<0.05). Consequently, beef from Si-fed Hanwoo had higher fat content, color and oxidation stability, and lower PUFA content than RVS-fed beef. And beef from Si+Cr-Met-fed Hanwoo had higher WHC, tenderness and color stability, and lower MUFA content than Si-fed beef.

Objectives : In order to study the clinical efficiency of Dohwatang, based on Oriental Medical References, using experimental animals, we studied ulcers, gastric juice secretion, free acidity, total acidity, and the action of transport rates in the intestine. Methods : We used rats administered with the above herbs. Results : Dohwa-tang showed remarkable inhibitory effects on peptic ulcers, gastric juice secretion, free acidity, and total acidity in pyloricligated rat. It also showed remarkable inhibitory effects on the transportability in the large intestine of rats. But Dohwa-tang didn't show any remarkable difference on stressed rats. Conclusions : Dohwatang works better for chronic pyloristenosis-peptic ulcer and for diarrhea than acute stress ulcer.

With the development of the chemical industry, the chemical accident is increasing every year, thereby increasing the risk of accidents caused by chemicals. The Ministry of Environment provides the criteria for determining shelter-in-place or outdoor evacuation by material, duration of accident, and distance from the toxic substance leak. However, it is hard to say that the criteria for determining the transition point are not clear. Transition point mean the time that evacuation method is switched from shelter-in-place to outdoor evacuation. So, the purpose of this study was to calculate appropriate transition point by comparing the cumulative toxic load. Namdong-gu in Incheon Metropolitan City was finally selected as the target area, considering the current status of the population of Incheon Metropolitan City in 2016 and the statistical survey of chemicals in 2016. The target materials were HCl, HF, and NH<sub>3</sub>. Modeling was simulated by ALOHA and performed assuming that the entire amount would be leaked for 10 min. Residents' evacuation scenarios were assumed to be shelter-in-place, immediate outdoor evacuation, and outdoor evacuation at an appropriate time after shelter-in-place. Based on the above method, the appropriate transition point from residents located in A(800 m away), B(1,200 m away), C(1,400 m away) and D(2,200 m away) was identified. In HCl, appropriate transition point was after 15 min, after 16 min, after 17 min, after 20 min in order by A, B, C and D. In HF, appropriate transition point was before 1 min or after 16 min, before 4 min or after 19 min, before 5 min or after 20 min, before 14 min or after 26 min in order by A, B, C and D. In NH<sub>3</sub>, appropriate transition point at A was before 4 min or after 16. Others are not in chemical cloud. This study confirmed the transition point to minimize the cumulative toxic load can be obtained by quantitative method. Through this, it might be possible to select evacuation method quantitatively that cumulative toxic load are minimal. In addition, if the shelter-in-place is maintained without transition to outdoor evacuation, the cumulative toxic load will increase more than outdoor evacuation. Therefore, it was confirmed that actions to reduce the concentration of chemicals in the room were necessary, such as conducting ventilation after the chemical cloud passed through the site.

This paper considers a parallel-machine scheduling problem with dedicated and common processing machines. Non-identical setup and processing times are assumed for each machine. A genetic algorithm is proposed to minimize the makespan objective measure. In this paper, a lowerbound and some heuristic algorithms are derived and tested through computational experiments.
