Allylaliphatic carboxylate oligomers were prepared from polymerization giving allyl aliphatic carboxylates in the presence of potassium persulfate in methanol and the α-sulfonation of these allyl aliphatic carboxylates oligomers were carried by direct addition of dry sulfur trioxide. The dispersing performance of oligomer type anionic surfactants and SDS in the aqueous suspension of Fe2O3 and Tio2 particles were evaluated by particle size distribution and ξ-potential measurement. As results, the particles of Fe2O3 and Tio2 were flocculated by addition of small amount of oligomer type anionic surfactants and SDS, then the flocks redispersed by more addition oligomer type anionic surfactants and SDS. The dispersion and flocculation were observed in lower concentration range of oligomer type anionic surfactants than SDS.

The antioxidant effect and sensory evaluation of various concentration of dried insam on gangjung was investigated for 6 months. The results were as follows: 1. The antioxidant effect of each sample were in the rank order of 0$gt;0.5$gt;1.0$gt;1.5$gt;2.0$gt;2.5% of dried insam at 20℃ by acid and peroxide value but the effect did not increase proportionally with increasing concentration. 2. In 3 months, acid and peroxide values increased slowly showing, but after 3 months, acid and peroxide values increased remarkably. 3. The acid value(AV) and the peroxide value(POV) of dried insam gangjung increased according to storage term but there was no significant difference with the kinds of adding methods of dried insam. 4. Sensory evaluation of preference for flavor, texture, taste and total quality of six samples by multiple paired comparison test indicated that gangjung with 1.5% dried insam in maltose was the best among samples.

Jeong-Gak is one of the Confucian architecture in Cho-Sun Dynasty. This study is founded on the architectural characteristics and the Confucian order of Jeong-Gak. The Cho-Sun Dynasty had put in operation positive Jeong-Pyo Policy for diffusion Confusion ethics and educate the people. Prize methods of Jeong-Pyo Policy are Jeong-Ryeo, Jeong-moon, remit corvee, present a post and present goods. Jeong-Moon and Jeong-Ryeo is red gate. Vocabularies of Jeong-Moon and Jeong-Ryeo have used mixing but I think that both meaning is different essentially each other. The red gate that elected in front of gate or gateway is Jeong-Moon and another red gate that elected an entrance a village is Jeong-Ryeo. Jeong-Moon and Jeong-Ryeo have no roof, so they are many problem for maintenance and management. Accordingly Jeong-Gak come out from the reign of King Jung-Jong because shelter of Jeong-Moon and Jeong-Ryeo. The function of the Jeong-Gak is shelter of the Jeong-Moon and Jeong-Ryeo, encouragement of Sam-Gang(三綱) ethics, and ostentation of a family. Besides it has a monumental characteristic. It has been distributed the whole country land that Jeong-Gak is closely related with the community of same family (rural community) the latter period of the Cho-Sun Dynasty. The architectural particularity of the Jeong-Gak is brilliance of building materials as compared with different Confucian architecture and appearance of various architectural type. It is that a type of Jeong-Gak appeared Jeong-Ryeo-Gak type, a lofty gate type, and Stone Jeong-Ryeo type. And there are keeping a rule that is to say Confucian order clearly.

We have investgated UV-Vis absorbance to observe the photoisomerization using the mixture solutions in chloroform and LB monolayers mixed with DLPE and 8A5H containing azobenzene which showed reversible cis-trans photoisomerization irradiated by alternate lights. We have found that the absorbance spectrums of the mixture solutions and LB monolayers were reversibly induced to cis-trans photoisomerization irradiated by alternate lights. In addition, the absorbance of both solution and LB monolayer mixed with 8A5H and DLPE were reversibly by alternate temperatures. As a results, the 1:1(by volume) mixture ratio of 8A5H and DLPE was more flexible and reversible cis-trans photoisomerization than the others.

This research was designed to develop a computer program and evaluate the nutritional balances especially the balance of fatty acids, amino acids and antioxidant vitamins for convenience foods. The Korean convenience food, Kimbab purchased from markets was evaluated by using the self-developed computer program. Contents of calories, protein and calcium were lower(1/3˚＋1/2) than the recommended levels of Korean adult woman, and the carbohydrate/ protein/ fat(CPF) energy ratio was 70: 13: 17. The mean P/ M/ S ratio was 2.2/ 1.4/ 1 and that of Ω6/ Ω3 fatty acids was 17.9/ 1, which was higher than the desirable ratio of 4~8/ 1. Average essential amino acid balance of market-Kimbab samples was within the desirable range even though the absolute amount of protein was lower than the recommended level. Contents of antioxidant vitamins (A, C &E) were lower than recommended levels. Two kinds of nutritionally adjusted Kimbab menu were established by self-developed computer program. Some of major changes was adding food ingredients such as tuna fish and perilla leaf cooked with sesame oil and soybean oil to increase Ω3 series fatty acids. Some fruits and milk were also added to the menu. The adjusted CPF ratios was 63: 15: 22 and the new values for P/ M/ S and Ω6/ Ω3 fatty acids ratios were 1.0/ 1.2/ 1/0 and 6.1/ 1 respectively. In sensory evaluation of two kinds of adjusted Kimbab, the taste and overall estimation scores were higher than unadjusted Kimbab. The computer program developed in this study might be used as a tool for the evaluation of nutritional balance of other convenience foods and menu planning.

Lipid peroxidation is one of the main manifestations of oxidative damage and has been found play an important role in the toxicity and carcinogenesis of many carcinogens. This study was carried out to investigate the effects of aflatoxin B₁ co-administrated with antioxidant vitamins on lipid contents and fatty acids components of liver in mice. For this work, vitamin C and vitamin E, the major antioxidants, were administrated with 10 ㎎/㎏ and 63.8 ㎎/㎏ respectively, through intraperitoneal(i.p) injection to male ICR mice, and 0.4 ㎎/㎏ of the AFB₁ injected by i.p. lhr later. The results were as follows: two fold amounts of free cholesterol, triglyceride, and total cholesterol in serum and liver of mice treated with only AFB₁ were observed, when compared to those of mice co-administrated with antioxidant vitamins. However, the levels of phospholipids in serum and liver of mice treated with only AFB₁ were decreased. Concerning to fatty acids composition of liver from AFB₁-treated mice, P/S ratio was shown more low level in cholesteryl ester, triglyceride, total cholesterol and phospholipid than those of mice co-administrated with antioxidant vitamins. In these data which provide with a reliable evidence on their antioxidantal effects to aflatoxicosis.
