Purpose: Lipid autoxidation of a soybean oil-in-water emulsion with high oil content was studied under after basil extract and/or iron addition. Methods: The emulsion consisted of tocopherol-stripped soybean oil (40 g), citrate buffer (60 g, pH 4.0), and/or $FeSO_4$ (0.5 mg) with 75% ethanol extract (200 mg/kg) of basil (Ocimum basilicum). Lipid oxidation was evaluated using headspace oxygen content, hydroperoxide contents, and p-anisidne values of the emulsion. Polyphenol compound retention in the emulsion during oxidation was determined spectrophotometrically. Results: Addition of basil extract significantly (p<0.05) decreased reduced hydroperoxide contents of the emulsion, and iron significantly (p<0.05) increased anisidine values and decreased oxygen contents. Co-addition of basil extract and iron showed significantly (p<0.05) lower reduced hydroperoxide contents in the emulsion than compared to those of the emulsion with added iron and the control emulsion without basil extract nor or iron. During the emulsion oxidation, polyphenol compounds in the emulsion with added basil extract were degraded, but more slowlywhich was slowed degraded in the presence of iron. Conclusion: The iIron increased the lipid oxidation through hydroperoxide decomposition, and basil extract showed antioxidant activity through radical-scavenging and iron-chelation. Polyphenol degradation was decelerated by iron addition, which suggested suggests iron chelation may be more preferred topreferentially activated over radical scavenging in the antioxidant action by of basil extract in the oil-in-water emulsion with high oil content.

One important online marketing practice to emerge in recent years is online behavioral advertising. Online behavioral advertising entails a range of issues, including the following: personal information collection and usage agreements (three conditions: no agreement, agreement, or agreement with a reward), consumers' levels of perceived personalization (low vs. high), and consumers' level of online privacy concerns (low vs. high). The effects of all these is what this study is designed to examine, as it evaluates online behavioral advertising. Study findings suggest that types of information collection and usage agreement play a pivotal role in the evaluation of online behavioral ads. Individuals who provided the informed consent form with the possible reward had a more favorable attitude toward the brand than individuals who provided the informed consent form without a possible reward. In terms of personalization, the level of perceived personalization of the advertising message impacted consumers' attitudes toward the online behavioral ad and toward the brand. Finally, online privacy concerns appear to impact consumers' attitudes toward the online behavioral ad and toward the brand. Theoretical and practical implications are also discussed.

This study was designed to observe the effects of the feeding of Hijikia fusiforme(Harvey) Okamura juice extract on the improvement of lipids in the serum of cholesterol-supplemented diet induced dietary hyperlipidemic rats fed experimental diets for 4 weeks. Concentration of total cholesterol and LDL-choloesterol in serum was significantly lower in the Hijikia fusiforme juice extract group than in the cholestero diet group. Concentration of HDL-cholesterol in serum was higher in the Hijikia fusiforme juice extract group than the cholesterol supplemented diet group. Those in the Hijikia fusiforme juice extract group were higher than those in the cholesterol diet group. In the ration of HDL-cholesterol concentration to total cholesterol concentration, Hijikia fusiforme juice extract administration group was higher percentage than the other groups. Atherosclerotic index was lower in the Hijikia fusiforme juice extract group than in the cholesterol diet group. Concentration of free cholesterol and cholesteryl ester in serum was rather lower in the Hijikia fusiforme juice extract group than the other groups. Triglyceride concentration in serum was significantly lower in the Hijikia fusiforme juice extract group than in the cholesterol diet group. Concentration of phospholipid in serum was more decreased in the Hijikia fusiforme juice extract group than in the cholesterol diet group. The activities of aspartate aminotransferase and alanine aminotransferase in serum were rather lower in the Hijikia fusiforme juice extract group than the cholesterol supplemented diet group. From the avove research, the Hijikia fusiforme juice extracts were effective on the improvement of the lipid compositions in serum of high fat diet induced dietary hyperlipidemic rats.

The purpose of this study was to investigate the effect of pretreatment with nicotinamide on the serum lipid composition and atherosclerotic index in streptozotocin ( STZ ) - induced diabetic rats. Nicotinamide pretreatment in STZ-induced diabetic rats inhibited the rise of serum glucose concentration. Serum total lipids and triglyceride levels in the STZ-induced diabetic rats were significantly higher than those in the control group. But in the group pretreated with nicotin-amide, triglyceride and lipid levels were significantly lower compared with those of STZ-induced diabetic rat group without nicotinamide. However, the serum phospholipid levels were not statistically different among treatment groups. In the STZ-induced diabetic group, the serum total cholesterol, VLDL, LDL-cholesterol levels and atherosclerotic index were higher and HDL-cholesterol level was lower compared to the control group. However, these changes were prevented by nicotinamide pretreatment. Pretreatment with nicotinamide significantly increased tile activities of serum lipase compared to the STZ-treated group. Aminotranferase (ALT, AST) activities were not significantly different in any of the groups.

From the 80% ethanol extraction of onion flesh, fraction I,II and III were separated by Sephadex LH-20 column chromatography. Fraction II and III had a high inhibitory effect on ACE and xanthine oxidase. The ACE was about 80% at 50 ppm of fraction IIand III. The xanthine oxidase was about 82.5% at 100 ppm of fraction In. This research was studied to investigate the effects of the fraction In isolated from onion on the reduction of fat accumulation in rats fed high fat diet for 2 months. The metabolism was examined by analyzing the fat in serum and liver. It was shown that cholesterol in serum was remarkably reduced in onion fraction In as compared with those of control.

This study was carried out to investigate the effect of the feeding mixture of linseed oil, rich in n-3 PUFA and the sunflower seed oil, rich in n-6 PUFA on the lipid metabolism in the dietary hyperlipidemic rats. After male Sprague-Dawley rats were induced hyperlipidemia by feeding the diet containing lard, butter and cholesterol for 3 weeks, then they were fed with the diet containing lard 3.0 % and butter 12.0% for control, the mixture in different proportion of both linseed oil and sunflower seed oil and antihyperlipidemic drugs for 2 weeks. Analysis of the lipid component of the serum showed following results. Concentration of total cholesterol in serum was significantly lower in the other groups except group 2 (lard 3.0 % + olive oil 12.0%) than in the control group , especially in groups 3 (cholestyramine 2.0%) and 5 (lard 3.0% + linseed oil 12.0%). HDL-C and the ratio of HDL-C to total cholesterol concentration were higher in groups 1, 3, 5 and 9 (lard 3.0% + sunflower seed oil 12.0%) , while the atherosclerotic index was low in groups3, 5. Concentrations of free cholesterol and choesteryl ester in serum were significantly lower in the other groups except group 2 than in the control group, especially lower in grop 5. Concentration of LDL was significantly higher in group 2 while it was remarkably lower in groups 3 and 5, while those of triglyceride in groups in 3 and 4 (lipraroid) were significantly higher than in the control groups. From the data on concentration of total choelsterol , HDL-cholesterol, LDL, phospholipid and triglyceride in serum, the results suggested that the feeding mixed with 3.0% lard and 12.0% linseed oil or 2.0% cholestyramine were most effective for the improvement of the serum lipids.

An arbitrator's duty shall be independence and impartiality such as a judge who has procedurally absolute position. Independence is the freedom from others, impartiality is the status of having no-partial condition. Although these show relevance between independence and impartiality, in actuality, it is not easy to prove them. Therefore, arbitrator has to prove his or her position by opening the public of reality and by having an obligation of notification. Each country which applies Arbitration rules or Arbitration act stays the same as Korean Commercial Arbitration Board does. Hence, each country has the moral principles in order to establish a standard of judgement for essential factors and requests preferentially the impartiality and the publicity. In reality, court of justice in England excludes arbitrator who has the close relation to a person concerned. Justice in France cancelled an authorization of arbitrator because of having the economic interest to the person concerned. And also, In United States, Federal Court reverses an arbitration judgment without giving any partiality to a person concerned because of not opening a public about the relationship between arbitrator and a person concerned. Therefore, decision basis of the independence and the impartiality is standardized by the economic interest of a person concerned, professional relation, society connection, relationship between arbitrator and arbitration representative in the same case while in process of arbitration, arbitrator's nationality If arbitrator does not keep the independence and the impartiality by a position of judge, he or she has to make responsible. this duty is divided by two things: civil case and crime case. and if arbitrator does break this responsibility, he or she will get the cancellation of judge and compensation of damage. However, Korea is placed in the real circumstance without judge precedent and moral principles including the independence and impartiality. In order to getting the good reputation of international arbitration institution, this country will have to enact principles of the independence and impartiality for arbitrator.

The onset time of sea breeze at Haeundae is faster than that at Suyoung in spite of the observation site at Suyoung being 5m and that of Haeundae being 1 km away from the coastline. We therefore simulate the effects of terrain on the onset time of sea breeze at Suyoung and Haeundae districts by using the LCM(Local Circulation Model). This phenomenon is due to the nighttime density flow, which is created by nighttime radiative cooling. It follows the slope of the highlands surrounding the urban area, gathers at a central area of Busan, and then flows out to a lower area like Suyoung river. This process continues after sunrise. In researching the AWS wind speed, we find an important thing. That is to say, the nighttime mean wind speed at Suyoung is three times greater than that at Haeundae. This property shows that Suyoung is an outflow channel of nighttime air mass. The above observed data shows that terrain effect has a important role on the onset of sea breeze.

In this article, we propose a near field microwave scanning probe structure in which two short conducting rods are attached to the center of the ridged(H-type) aperture, thereby reducing significantly the beam spot area while maintaining the high transmission efficiency through the output coupling H-type(ridged) aperture. Here the two short parallel conducting rods seem to play an important role of concentrating the transmitted electromagnetic energy through the H-type aperture and so reducing the beam area for high resolution. For validation of the proposed theory, the near field waveguide probe is fabricated according to the simulated results and its return loss characteristics versus frequencies are measured. The comparison between theory and experiment is seen to be in good agreements.

This study was carried out to investigate the effect of the feeding mixture of linesed oil, rich in n-3 PUFA and the sunflower seed oil, rich in n-6 PUFA on the lipid metabolism in the dietary hypprlidemic rats. After male Sprague-Dawley rats were induced hyperlipidemia by feeding the diet containing lard, butter, and cholesterol for 3 weeks, then they were fed with the diet containing lard 3.0% and butter 12.0% for control, the mixture in different proportion of both linseed oil and sunflower seed oil, and antihyperlipidemic durgs for 2 weeks. Analysis of the lipid component and the fatty acid composition of the liver showed following results. Concentration s of the total cholesterol and phospholipid in liver were significantly higher in group 2 (olive oil 12.0%) and lower in the other groups than in the control group, especially lower in groups 3 (cholestyramine 2.0%) and 9 (sunflower seed oil 12.0%) . Concentration of triglyceride was lower in the other groups except group 4 (liparoid), especially lowe rin group 9 than in the control group. In the fatty acid composition of liver lipids, C18:2 was the major fatty acid. Contents of n-6 PUFA increased , while those of n-3 PUFA decreased in groups composition of the test lipids. From the data on concentration s of total cholesterol. Phospholipid and triglyceride in liver, we concluded that the feeding mixed with 3.0% lard and 12.0 % sunflower seed oil were most effective for the improvement of the live lipids. The fatty acid composition in liver lipids were affected by the fatty acid composition of the test lipids.
