Regular exercise is effective in preventing coronary disease such as angina pectoris and infarction, inside it can lower the blood pressure and aids in weight control and release of stress. Risk factors of arteriosclerosis is hypertension, hyperlipidemia, diabetes, obesity, physical inactivity and excessive smoking. Arteriosclerosis begins at young age worsens with age, particulary in male. For people with risk factors of arteriosclerosis, it is important to prevent arteriosclerosis-related disease with dietary, living pattern and exercise prescription. Dietary fibers promote exercise of the digestive tract and shortens the time food remains inside the digestive tract. It can prevent obesity, hyperlipidemia, arteriosclerosis and colin cancer by blocking the absorption of cholesterol. Various vegetables and sea foods are lichen unsaturated fats and prevent the absorption of cholesterol inside the digestive tract. Essential fatty acids and unsaturated fats which are contained in vegetable oils, promotes metabolism while preventing absorption. In fruits, pectin water-soluble fiber, is present and lowers the level of cholesterol. By consuming foods that low in cholesterol and saturated fats, and rich in unsaturated fats, aliomentotherapy alone can reduce the plasma cholesterol by 10~l5$\%$. For ideal exercise, it should be aerobic with intensity of 60~80$\%$ HRmax, duration of 15~60min/day. The frequancy of 3~6/week is desirable the better exercise prescription is endurance aerobic exercise. To get more effect exercise, exercise consistency is very important.

Palmitoyl-oleoyl-oleoyl (POO) and palmitoyl-oleoyl-palmitoyl triacylglycerol rich fraction (PSL) was obtained from the acetone fractionation of palm stearin. The fatty acid composition (total and positional), tri-acylglycerol species, and solid fat index (SFI) were compared among the blends of natural vegetable fats (sal fat, illipe fat, kokum fat, shea stearin fat, and shea butter) and PSL with different ratios (50:50, 60:40, 65:35, 70:30). In total fatty acid composition of PSL, palmitic, oleic, and linoleic acids were the major fatty acids, whereas in natural vegetable fats stearic and palmitic acids were the major fatty acids. Moreover, oleic acid was a major fatty acid at sn-2 position in sal fat, illipe fat, and kokum fat. The TAG species was analyzed by reversed-phase HPLC, from which the PN value ranged from 46 to 54. When natural vegetable fats and PSL were blended with different ratios, decreasing the amount of PSL resulted in increasing SFI in most cases. Among blends, the SFI of sal fat and PSL were most similar to commercial cocoa butter equivalent (CBE).

Each kinds of the leather process wastes which is occurred in the leather making process is almost more than 50% on the basis of the raw hide. The emitted process wastes are important oil and fats and protein resources because they are composed of animal oil and fats and fibrous protein. But most of them are incinerate or filled up simply as the industrial wastes without applying to recycling into the other use. Thus the problems of environmental pollution are becoming more critical and the processing cost of the leather process wastes (40,000~60,000 won) is a heavy burden on the production cost. Because the organic wastes such as fleshing scrap, pelt scrap are high fetid, its unlawful abandonment without being processed properly causes the occurrence of secondary pollution by an offensive odor and leakage of waste water. Thus we made the re-resource experiments in order to resolve this problems. The principal contents of this study are to process the collected leather waste scrape through separate the oil and fat ingredients with various propert by processing various chemicals and enzymes on the next effector. The re-resource application of separated oil and fat ingredients produced chemical for leather applicable to manufacturing process of leather through chemical transformation process(sulphation reaction, sulphitation reaction etc.) of oil and fats.

Increasing use of plastics in food packaging materials has led to the issue of food-plastic packaging materials's mutual interactions. Although the plastic packaging materials are generally considered as inert, migration and sorption of fatty materials are some of the problems associated with their use. So, this work investigated the compatibility of three structurally different polymers, polypropylene (PP), polyethyleneterephthalate (PET) and ethylene vinyl alcohol copolymer (EVOH) with some structurally different food fats. The main goal was to study the sorption of food fats by the plastic films and to see what extent mechanical properties of the plastic films was affected by plasticization effect due to sorption of fatty materials. PP, PET, and EVOH films was immersed in pure triglycerides, and then extracted with hexane and analyzed for the amounts of fat migrated. The sorbed films were also investigated for change in mechanical properties. Result showed that structural factor of the films and fatty materials plays important role in th migration process. The fat with the simplest structure are migrated more easily that the fat with more complex structure. However, structural effect of migration was varied according to degree of crystallinity and density of plastic films. In addition to that, polarity of plastic film was affected migration of fatty materials significantly. Additional research is needed to justify the reason why migration of fatty materials into the films was affected by polarity and structural integrity.

Objective: In order to utilize fat from broiler byproducts efficiently, it is necessary to develop an appropriate rendering procedure and establish quality information for the rendered fat. A study was therefore undertaken to evaluate the influence of rendering methods on the amounts and general properties of the fat recovered from broiler skin. Methods: The yield and quality of the broiler skin fat rendered through high and lower energy microwave rendering (3.6 W/g for 10 min and 2.4 W/g for 10 min for high power microwave rendering (HPMR) and high power microwave rendering (LPMR), respectively), oven baking (OB, at $180^{\circ}C$ for 40 min), and water cooking (WC, boiling for 40 min) were compared. Results: Microwave-rendered skin exhibited the highest yields and fat recovery rates, followed by OB, and WC fats (p<0.05). HPMR fat had the highest $L^{\star}$, $a^{\star}$, and $b^{\star}$ values, whereas WC fat had the highest moisture content, acid values, and thiobarbituric acid (TBA) values (p<0.05). There was no significant difference in the acid value, peroxide value, and TBA values between HPMR and LPMR fats. Conclusion: Microwave rendering at a power level of 3.6 W/g for 10 min is suggested base on the yield and quality of chicken fat.

The present study was carried out in normocholesterolemic New Zealand white(NZW) rabbit, to evaluate the effect of dietary supplementation with Korean pinenut oil, on plasma lipids, plasma lipoproteins, liver lipids and platelet aggregation. NZW rabbits were fed for 80 days on a commercial chow diet supplemented with 5% of energy as fats(soybean oil or pinenut oil) or 10% of energy as fats(soybean oil or pinenut oil). A control group was fed a commercial stock diet. There were no significant effects of pinenut oil on plasma free cholesterol, HDL-cholesterol, triglycerides, glucose and lecithin-cholesterol acyltransferase, as compared with those obtained from rabbits fed the soybean oil diet. After 80 days, the concentration of plasma free fatty acid in only the pinenut oil group was significantly decreased by about 50% relative to the control diet. At the end of the dietary treatment, liver triglycerides and phospholipids were significantly decreased in the pinenut oil group, compared to the how diet, whereas the soybean oil-consuming rabbits had only significantly decreased phospholipid levels. Cholesterol contents of liver were unaffected by type of dietary fat. At the end of 80 days, a diet containing pinenut oil resulted in a decrease in apolipoprotein B and the apo B/apo AI ratio as compared with the stock diet or soybean oil diet. Platelet aggregation induced by collagen or arachidonic acid was depressed significantily in pinenut oil diet.
