This study evaluated the hypolipidemic effects of Eleutherococcus senticosus combined with several oriental medicinal herbs. In addition, it addressed whether consuming a diet of healthy food along with a daily supplement of this composite could affect the health status of individuals suffering from diet-related disease such as obesity and hyperlipidemia. The effects of the combined medicinal herbal extracts(MHE) extracted with hot water on reducing serum lipids and improving blood parameters were examined in rats fed a high-fat diet for 5 weeks. Sprague-Dawley rats were randomly assigned to 4 groups: basal diet only(BDG), high fat diet without MHE(FCG), high fat diet and 10% MHE(F10E) and high fat diet and 20% MHE(F20E). Serum lipid contents and blood variables were examined after the experimental period. The results of were as follows. The hematological data for the 4 groups were similar indicating no significant differences. There were moderate level of serum GOT activity in the F10E and F20E groups as compared to the FCG group. Total cholesterol, LDL-cholesterol, triglyceride in serum and the atherogenic index were remarkably reduced in the MHE-supplemented groups as compared to the control group. However, F10E and F20E groups had significantly higher HDL-cholesterol levels than the control group. These results imply that combination of several medicinal herbal extracts could be used to reduce of serum lipid concentrations. The data from this study will be used as basic information with the field of functional food research to address how we can apply oriental medicinal resources to foods. Such research currently drawing considerable attention world-wide.

The purpose of this study was to investigate the effects of proteolytic enzymes in Letinus edodes powder which has the ratio of 0%, 2%, 4%, and 8% on the tenderness and sensory characteristics of beef. Beef eye of rounds were marinated in distilled water (Control), 2% L. edodes (L2), 4% L. edodes (L4), and 8% L. edodes (L8). As a result, the enzyme activities have shown to have higher activity (p<0.001) as the amount of freeze-dried Letinus edodes powder increased. The pH and color of the meat were slightly different between the C (control) group and the sample groups. The cooking loss showed the lowest value of control (p<0.01), and water holding capacity showed the highest value of L8. Furthermore, the sample groups exhibited lower shear force values compared with the control (p<0.05). L4 and L8 showed muscle proteolytic effects compared with the control. In case of sensory evaluation, L4 showed significantly higher values in terms of color (p<0.05), flavor (p<0.01), taste (p<0.01), tenderness (p<0.01), juiciness (p<0.01), and overall acceptance (p<0.01). Based on the results, this study conclude that adding of 4% around freeze-dried Letinus edodes powder may be the best optimization ratio for sensory character and tenderization of the beef.

Much work has already been done to control and regulate the worldwide problems caused by climate change, particularly the issues on greenhouse gas (GHG) emissions. Carbon dioxide ($CO_2$), having the highest form of concentration among GHGs composed around 1.0 billion tons of emission, and comprises about 98% of the total emissions from the shipping industry. Korean trade mainly rely on the sea transportation. Korean ship tonnages that was brought about by shipbuilders all over the country, continues to grow annually due to the prevailing demands on goods or material supplies and depicting only a small part of the global maritime activity. Nowadays, new build ships coming from the Korean Shipbuilders are being optimized by hull, structure and appendages design, The operational capability of the propulsion and auxiliary machineries in its maximum capacity to achieve the highest possible efficiencies for energy and onboard power use to mitigate $CO_2$ emissions are continually being done through the help of research and development. In this paper, the energy efficiency design index and anboard power capacity of Korean new build ships have been analyzed with response to data collected by ship types, and its respective fuel consumption in relation to $CO_2$ emission results. In response to climate change convention outcome proposals, the best way for the new build ships to become energy efficient is by lowering its operational speed thru adopting the state of the art diesel propulsion engines, patronizing the best sailing practice to lower the transportation cost on the different sea trade routes also helps in $CO_2$ mitigation.
