In recent years, polyphenol-rich herbs, fruits and processed foods, which are made of plant origin, have attracted much attention due to their potential health benefits. Pomegranate (Punica granatum L.) is an important source of bioactive compounds and has been used to treat diseases because of its medicinal properties. This research was focused on characterizing Korea's national cultivar and a similar product from California, USA. To evaluate their bioactive compounds and pharmacological activities, their anti-oxidation and cancer inhibition properties, as well as their organic acid and free sugar contents, were investigated. The national cultivar had low total sugar and high organic acid contents, contrary to the imported product. The results showed that the peel of national cultivar had high polyphenol and ellagic acid contents compared to imported product. The free radical scavenging capacity was evaluated via 2,2-diphenyl-1-picrylhydrazyl (DPPH) and its positive correlation with the total polyphenol contents was found. The anti-cancer activity of methanol extracts revealed growth inhibition against the prostate cancer cell. These results signify that while pomegranate, national cultivar, is more sour than the imported product, its health benefits could be excellent. Also, the polyphenol compound content of the non-edible part (such as the peel and the seed) was higher than that of the juice. Thus, it is suggested that the byproduct of the juice extraction could be potentially used in other fields such as medicine or dietary agents.

Yogurt contains many microorganisms that are beneficial to human health, and is a probiotic that supplies many nutrients such as calcium and protein. It is difficult to safety preserve for a long time because it possesses a high content of water. To address this problem, powdered "instant" yogurt has been developed, but it has flaws low flowability and solubility. Therefore, yogurt was granulated using a fluidized bed granulator to increase flowability and solubility. The fluidized bed granulator was designed by using response surface methodology (RSM), whose variables were feeding rate (FR), atomization air pressure (AP) and product temperature (PT). After being granulated, the yogurt was analyzed for yield and lactic acid bacteria count. The maximum yield of yogurt granules was 79.42%, at FR of 0.54 mL/min, AP of 2.64 kPa, and PT of $58.18^{\circ}C$, and the colony count for lactic acid bacteria was more than $6log^{10}\;CFU/g$. Therefore, spherical granulation of yogurt using a fluidized bed granulator could be used for making convenient probiotic products with improved flowability and solubility.

Jeju Sasa borealis (S. borealis) is indigenous to the Halla Mountain area of Jeju Island, Republic of Korea. However, its dominance has retarded the development of other plant species and lowered biodiversity in this region. The aim of this study was to determine whether S. borealis silage (SS) supplementation affects the chemical composition and antioxidant activity in the fresh meat of Korean native goats (Capra hircus coreanae). The experiment was conducted on 12 Korean native goats at the finisher stage. The feeding groups were the Control (total mixed ration, TMR) and the Treatment (80% TMR + 20% SS). The animals were adapted for two weeks and then subjected to a six-month breeding experiment. Meat samples were excised from the neck, loin, rib, front leg, and hind leg of the slaughtered animals. The meat derived from the treatment group contained more taurine and anserine than that derived from the control group. Both groups did not significantly differ in terms of ω-6/ω-3 fatty acid ratio. The loin and front leg of the treatment group contained significantly higher vitamin E levels than those of the control group. DPPH, ABTS, and FRAP analyses disclosed that the loin and front leg had significantly higher antioxidant activity (p<0.05) than the other parts. Moreover, the loin and front leg cuts of the treatment group had higher antioxidant activity than those of the control group. The present study demonstrated that S. borealis supplementation could effectively improve Korean native goat meat quality.

This study was carried out to find the problems of assessment on terrestrial ecosystem part in environmental impact analysis(EIA) and to suggest the proper amelioration measures by analyzing 19 environmental impact statements(EIS) published during the period from 1991 to 1994. The results obtained from this study were as follows. Field survey for the investigation of fauna and flora in project areas should be conducted at least 3 times a year and name of investigator should be written on the EIS clearly. Increase or decrease in degree of green naturality and productivity cannot be an absolute criteria for expressing the amount of changes in ecosystem. Evaluation for the ecosystems and their composition in project area is more important than presenting merely the increase or decrease in degree of green naturality and productivity. Alleviation measures in 19 EISs analyzed in this study were summarized into 6 types: They are establishment of landscape plan, transplanting of useful trees preservation of big tree and protected species, restoration and preservation of existent vegetation, establishment of soil conservation measures and diminution of the impact on animal. However, they were somewhat insufficient because they wouldn't suggest the alleviation measures in detail. The more positive counter-proposals are needed to decrease the impact of the project on terrestrial ecosystem.

This study was carried out to investigate the antioxidative activity and cytotoxicity on human KB cell of extract from Rhododendron mucronulatum flower, and also to determine the contents of total polyphenol and flavonoid. The methanol extract of Rhododendron mucronulatum flower was fractionated with various solvents such as hexane, chloroform, ethyl acetate, butanol and water. The DPPH radical scavenging activities of ethyl acetate fraction had stronger activity than other fractions. So, antioxidative substances of ethyl acetate fraction were crude purified by silica gel column chromatography. The DPPH radical scavenging activities of crude purified fraction 2 and 3 were more than 90% at 40 ppm. In the presence of $100{\mu}g/mL$, growth inhibition on human KB cell by WST-1 assay showed 81.2% in chloroform fraction and 74.6% in hexane fraction. The contents of total polyphenol and flavonoid of ethyl acetate traction were 32.70% and 20.30%, respectively, The antioxidative activity showed correlation with total polyphenol and flavonoid contents.

This study aimed to assess the in vitro safety of a probiotics mixture (Lactobacillus acidophilus PBS066, Lactiplantibacillus plantarum PBS067, and Limosilactobacillus reuteri PBS072), along with its inhibitory effect on carbohydrate digestion. All three strains met the antibiotic resistance profile of the European Food Safety Authority (EFSA) guidelines. None of the strains exhibited hemolytic activity or cytotoxicity against Caco-2 cells. Strains PBS067 and PBS072 inhibited α-amylase activity, whereas all three strains suppressed α-glucosidase activity, indicating that the mixture might limit carbohydrate digestion in the gastrointestinal tract. These findings support the safety of this probiotics mixture and its potential to modulate carbohydrate metabolism in the gut.
