To examine the antioxidant activity of grape seed ethanol extract, the antioxidative index (AI) by the active oxygen method (AOM) and peroxide value (POV) of linoleic acids containing the extract at levels of 100, 500, 1000 ppm was measured during storage at 6$0^{\circ}C$ for 12 days. When comparing with BHT, the extract at levels of 500 ppm showed similar or better antioxidant activity (AI: 2.25, POV: 57 meq/kg oil) than that (AI: 1.21, POV:58 meq/kg oil ) of BHT at 200 ppm level. The mixture of 500 ppm of the extract and 500 ppm of ascorbic acid showed intense synergistic antioxidant activity (AI: 6.21, POV: 14 meq/kg oil) compared with using 1000 ppm of the extract only (AI: 3.39, POV 43 meq/kg oil). Also to determine the feasibility of using the extract for natural antioxidant, the oxidative stability of roasted peanut and Ramyon was investigated by measuring the POV of crude oils from the samples stored at 60"C for 18 days. The oxidative stability of roasted peanut and Ramyon seemed to be enhanced by treatment with the extract at level of 1000 ppm, especially with the 1 : 1 mixture of extract and ascorbic acid. This study suggested that grape seed ethanol extract could be used as the natural antioxidant for the improvement of overall oxidation stability of fat containing foods.oods.

This study investigated the effect of oxidized soybean oil in the diet of young chickens on growth performance and intestinal oxidative stress, and indices of intestinal immune function. Corn-soybean-based diets containing 2% mixtures of fresh and oxidized soybean oil provided 6 levels (0.15, 1.01, 3.14, 4.95, 7.05, and $8.97meqO_2/kg$) of peroxide value (POV) in the diets. Each dietary treatment, fed for 22 d, had 6 replicates, each containing 30 birds (n = 1,080). Increasing POV levels reduced average daily feed intake (ADFI) of the broilers during d 1 to 10, body weight and average daily gain at d 22 but did not affect overall ADFI. Concentrations of malondialdehyde (MDA) increased in plasma and jejunum as POV increased but total antioxidative capacity (T-AOC) declined in plasma and jejunum. Catalase (CAT) activity declined in plasma and jejunum as did plasma glutathione S-transferase (GST). Effects were apparent at POV exceeding $3.14meqO_2/kg$ for early ADFI and MDA in jejunum, and POV exceeding $1.01meqO_2/kg$ for CAT in plasma and jejunum, GST in plasma and T-AOC in jejunum. Relative jejunal abundance of nuclear factor kappa B ($NF-{\kappa}B$) P50 and $NF-{\kappa}B$ P65 increased as dietary POV increased. Increasing POV levels reduced the jejunal concentrations of secretory immunoglobulin A and cluster of differentiation (CD) 4 and CD8 molecules with differences from controls apparent at dietary POV of 3.14 to $4.95meqO_2/kg$. These findings indicated that growth performance, feed intake, and the local immune system of the small intestine were compromised by oxidative stress when young broilers were fed moderately oxidized soybean oil.

In the fish oil forced oxidized at 6$0^{\circ}C$ for 10 days, changes in the levels of peroxide (POV), anisidine (AnV), total oxidation (Totox), iodine (IV), acid (AV) and fatty acids composition were measured. The levels of POV, AnV and Totox remained unchanged or decreased after reaching the maximum. The concentrations of polyunsaturated fatty acids (PUFA) such as Docosa hexaenoic acid (DHA) or Eicosa pentaenoic acid (EPA) decreased with extended oxidation of fish oil. In saturated fatty acids (SFA) like C16:0, their concentration increased with decreasing PUFA. The ratios of PUFA/SFA and DHA/C16:0 decreased with extended oxidation of fish oil. Using a single parameter of POV, AnV, Totox, AV, IV, or fatty acids for evaluation of the quality of fish oil may prove difficult. Besides other parameters, the ratios of PUFA/SFA and/or DHA/C16:0 could be a good index to evaluate the quality of fish oil.

1. For the induction of ceroidosis, the flounders were fed on the different Peroxidation Value(POV) diets for 6 months from April 1 to September 27, 1991. The growth of the flounder fed on the high POV diets, 90.4mEq/kg and 36.9mEq/kg, were markedly decreased after 3 months and 4 months respectively, compared to those fed on the two different low POV diets, 15.5mEq/kg or 15.2mEq/kg. 2. Histologically, it was hard to observe any pathological signs in the tissues of the control group with normal diets(POV 10.5mEq/kg). With the increasing of POV values of diets, severe ceroid accumulation and parenchymal degenerative lesions were found in the liver, spleen and kindeny. However, any abmormalities were not observed in muscle and intestine been in high POV diets fed flounder.

This study takes a close look at the recent success of independent documentaries to find its implications and a way to invigorate Korean documentary ecosystems. To this aim, this study performed in-depth interviews with independent documentary film makers and television documentary directors. Also, it analyzed the case of POV (Point Of View), which is television's longest-running showcase for independent documentary films in the USA. The results display that independent documentaries convey competitive edge of contents and expansion of distribution and funding through film industry systems, based on the producer systems, global distribution networks of overseas pitching and film festivals, marketing and audience strategy of film industry. Although this shows its molding of documentary industry ecosystems, there are great needs for various platforms other than film industrial outlet in order to make an advancement of the ecosystems under the digital environment. POV works on the basis of 'open sourcing' form when collaborating with independent film makers. Independent documentaries picked up by POV are aired on PBS, streamed via its online service, and distributed through community screenings; this three-outlet strategy makes POV a unique platform and has a relevance and feasibility to apply for Korean documentary ecosystems. Therefore, this study suggests to create a platform adopting POV system hoping that more studies and efforts would come for various and novel platform building so to make more advanced and invigorated ecosystems of Korean documentary.

The antioxidative capacity of Monascus koji was studied in raw bologna-type sausage by measuring thiobarbituric acid reactive substances (TBARS) and peroxide values (POV) during storage at $25^{\circ}C$ for 7 days. The addition of 2% Monascus koji effectively inhibited lipid oxidation in the mixture without vitamin C and NaNO$_2$, evidenced by its prevention of an increase in TBARS and a significantly reduction in increases in POV. Monascus koji in raw minced processed meat significantly improved the shelf life of the food.

1. By feeding on high Peroxidation Value(POV : 90.4mEq/kg) diets for 180 days, the cultured flounder were induced ceroidosis antificially. 2. The supplementation of glutathione to the diets having POV of 15.5mEq/kg improved the growth of the flounder that had shown depressed by the previous high POV diets(90.4mEq/kg). However, we found very much the same degree of improvement on growth by the supplemented diets of glutathione from 10mg/kg/day to 40mg/kg/day. 3. After 7 days, the flounder fed on the diets supplemented with 10, 30mg/kg/day glufthione start the recover from the accumulated ceroid and damaged tissues. These treated flounders with glutathione showed completely normal histlogical signo after 21 days. The effect of glutathione treatment with high concentration(30mg/kg/day) was better than that of low concentration(10mg/kg/day).

The impact of storage temperature on the changes in acid value(AV), peroxide value(POV), color value, total phenolic content(TPC), and antioxidant activity in perilla seed(PS) was investigated. The PS was stored at 25, 35, and 45℃ for four weeks. An increase in the storage temperature resulted in significantly increased AV, POV, redness, and yellowness of the PS. Conversely, TPC, antioxidant activity, and redness of the PS significantly decreased. The changes in the AV and POV followed a first-order kinetic model, and the kinetic parameters such as k, t_1/2, Q₁₀ and Ea were calculated. The k and t_1/2 values decreased with increasing storage temperature and the Q₁₀ values for the AV and POV were 1.56, 1.91, 4.61, and 3.43, respectively. The Ea for the changes in of the AV and POV in the PS were 70.40, 102.63 kJ/mol, respectively. The half-life values for the AV and POV of the PS at 25℃ were 169.52 and 373.18 days, respectively, while the values at 45℃ for those, were 28.47 and 27.93 days, respectively.
