This study was performed to investigate the influence of Chlorella which effected the change of Pb contents, enzyme activity and lipid compounds on the rats fed the beverage involved Pb and the different contented Chlorella added-diets for 18weeks. The rat`s weight of 200ppm Pb group was decreased 6.04% and the cause of that was Pb intake. But the rat`s weight of Chlorella added-diets+200ppm Pb group was increased 4.02%(p<0.01). When feeding the different(0%, 2%, 5%, 10%) Chlorella added-diets with the Pb contented beverage to the rats, we could know that the Pb contents accumulated on tissue were decreased to 20.70(0%), 12.88(2%), 14.83 (5%) and 19.56(10%), compared with the quantity of Pb taken in. Total-cholesterol, triglyceride, glucose content and AST, ALT, ALP, LDH enzyme activity in serum were the highest on 200ppm Pb group and those were decreased by the order of different (2%∼5%>10%) Chlorella contents +200ppmPb group. A significance was recognized on the level of 1%. Therefore, when rats were exposed to Pb, it was thought that the amount of Chlorella intake was adequate on content 2∼5% for reducing the lead toxicity.

1. 수축기 혈압은 운동을 하고 있는 군에서 약간 낮았으나 이완기 혈압은 유의성 있는 차이를 보이지 않았다. 운동을 하고 있는 여대생의 경우 체지방량이 낮게 나타난 반면 제지방량은 변화가 없어 운동 여부에 의한 차이가 거의 보이지 않았다. 또 혈중 포도당 함량은 규칙적인 운동을 하고 있는 여대생에서 다소 높은 수준이었다. 2. 체지방율은 지속적인 운동을 하고 있는 여대생에서 유의성은 없었지만 약간 낮았으며 혈청 총콜레스테롤과 중성지방의 농도 역시 유의성 있게 낮게 나타났다. HDL 콜레스테롤 농도는 두 군 모두 거의 비슷한 수준으로 군간에 뚜렷한 차이를 보이지 않았던 반면 LDL 콜레스테롤의 경우 운동에 의해서 유의성 있게 낮게 나타났다. 따라서 규칙적인 운동에 의해서 HDL-Chol/Total-Chol 비율은 증가되었으며 LDL-Chol/HDL-Chol의 비율은 낮았다. 3. 혈액중 지단백질의 상대적인 분포는 HDL(%)의 경우 지속적인 운동을 하고 있는 여대생의 경우 일반 여대생에 비해 거의 차이가 없었고LDL(%)는 유의성 있게 낮았던 반면 VLDL(%)는 오히려 높게 나타났다. Plasma의 지방산 조성중 포화 지방산 함량은 운동을 하고 있는 여대생에서 약간 높았지만 다가 불포화 지방산 함량은 같은 수준으로 두 군간에 차이를 보이지 않았다.

As already pointed out increasing the concentration of dried insam with gangjung becomes progressing the antioxidant effect: 1. The antioxidant effect of gangjung with undried insam increased than gangjung and above 6.0% of undried insam is same of the storage stability, 6 months 2. The more increased acid value(AV) and the peroxide value(POV) of susam gangjung the longer period of storage, but there was no significient difference with the kinds of adding methods. 3. Sensory evaluation of preference for flavor gangjung with increased according to increasing concentration of undried insam but 6.0% undried insam in maltose was the best among samples.

In search for several fatty acid with unusual structure in vegetable oils, we have found that unknown peaks were shown on GLC in the analysis of fatty acids of the lipids from the pulp of ripened jujube (Zizypus jujuba var. inermis) fruits. These fatty acids were identified as a series of cis-monoenoic acids with Ω-5 double bond system such as C14:1Ω5, C16:1Ω5 and C18:1Ω5, including Ω-7 fatty acid as C16:1Ω7 and C18:1Ω7, by GLC, solid-phase extraction silver ion-column chromatographic, GLC-mass spectrometric and IR techniques. First of all, total fatty acid methyl esters were resolved into saturated and branched fatty acid, monoenoic acid, dienoic acid, and trienoic acid fraction, respectively, with 100% dichloromethane (DCM), DCM/acetone (9:1, v/v) 100% acetone, and acetone/ acetonitrile (97:3, v/v) solvent system. Unknown fatty acids were included in the monoenoic fraction and were confirmed to have cis-configuration by IR. Picolinyl esters of monoenoic fatty acids gave distinct molecular ion peak and dominant diagnostic peaks, for example, m/z 317, 220 and 260 fragment for cis-C14:1Ω5, m/z 345, m/z 248 and 288 fragment for cis-C16:1Ω5 and m/z 373, m/z 276 and 316 fragment for cis-C18:1Ω5. In this way the occurrence of cis-C16:1Ω7 and cis-C18:1Ω7 could be deduced from the appearance of prominent fragments as m/z 345, 220 and 260, and m/z 373, 248 and 280. Level of total Ω-5 fatty acids amounted to about 30% in the fatty acid composition with the predominance of C16:1Ω5 (18.7~25.0%), in the semi-ripened and/or ripened samples collected in September 14 (C16:1Ω5 ; 18.7%, C14:1Ω5 ; 3.6% and C18:1Ω5 ; 3.0%), September 22 (C16:1Ω5 ; 25.0%, C14:1Ω5 ; 1.4% and C18:1Ω5 ; 2.6%), and October 7 (C16:1Ω5 ; 24.7%, C14:1Ω5 ; 7.7% and C18:1Ω5 ; 2.5%). However, the lipids extracted from unripened jujube in July and August contain these unusual fatty acids as low as negligible. It could be observed that the level of Ω-5 fatty acids in the pulps increased sharply with an elapse of ripening time of jujube fruits. Other monoenoic fatty acids with Ω-7 series, C16:1Ω7 (palmitoleic acid) and C18:1Ω7 (cis-vaccenic acid) could be detected. And in the lipids of the kernel and leaf of jujube, none of Ω-5 fatty acids could be detected.

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.
