This study was conducted to investigate the influence of dietary olive oil, canola oil, or sardine oil on the fatty acids composition and cholesterol contents in eggs The experimental layers, 62~65 weeks of age, were randomly allotted to one of the four treatments; a) Control (commercial feed), b) T1 (commercial feed plus 10% olive oil), c) T2 (commercial feed plus 10% sardine oil), d) m (commercial feed plus 10% sardine oil) for 3 weeks. The egg samples were stored at 4${\pm}$1˚C for a certain period (1, 3, 5, 7, and 9 days) and analyzed for the fatty acids composition and cholesterol contents. The unsaturated fatty acid contents in the egg yolk were slightly decreased as the storage periods extended. The oleic acid content in T1 was the highest in all treatments. The linoleic and linolenic acid contents in T2 were higher than in the other treatments. The eicosahexaenoic acid (EPA), docosapentaenoic acid (DPA), and docosasahexaenoic acid ( DH A) contents in eggs from m were higher than the other treatments. The ratio of egg yolk n-6 /n-3 fatty acids contents in all treatments were slightly increased as the storage periods extended. The n-3 fatty acid contents of the egg yolk from T3 was the highest in all treatments. The cholesterol contents of the eggs were significantly decreased as the storage period extended(P<0.05). There was no significant difference in egg cholesterol content among all treatments.

In a previous paper, we showed that 5-aminosalicyl-L-aspartic acid (5-ASA-Asp) has much greater deconjugation efficiency in the cecal contents than does 5-aminosalicyl-L-glutamic acid (5-ASA-Glu). To explore a reason for ineffective deconjugation of 5-ASA-Glu, structural analysis of the conjugate was performed. Aromatic acyl-L-glutamic acid derivatives, N-benzoyl-glumatic acid (BA-Glu), N-(2-hydroxybenzoyl)-glutamic acid (SA-Glu), N-(3-aminobenzoyl)-glutamic acid (3-ABA-Glu) and N-(4-aminobenzoyl)-glutamic acid (4-ABA-Glu), were prepared and incubated in the cecal contents. The deconjugation rates were compared with that of 5-ASA-Glu. The order of the rates was BA-Glu $\approx$ 4-ABA-Glu $\approx$ 3-ABA-Glu $\gg$ SA-Glu $\approx$ 5-ASA-Glu. The deconjugation of the aromatic acyl-L-glutamic acid derivatives was carried out by enzyme(s) in the cecal contents since the deconjugation did not occur in the autoclaved cecal contents and on incubation with N-benzoyl-D-glutamic acid. Our data suggest that the 2-hydroxyl group in 5-ASA is ascribed to the poor deconjugation of 5-ASA-Glu in the cecal contents.

To know a degree of pollution in agricultural products cultivated around 4 unworked mines located in Chollanam-Do, we investigated a concentration of trace metal to provide the basic data for its residual limits. 28 samples of seven kinds of agricultural products (lettuce, onion. potato, radish, pepper. pumpkin, bean) collected from 4 unworked mines located in Chollanam-Do in 1999 were analyzed by Mercury Analyzer for mercury and Atomic Absorption spectrophotometer for Pb, As, Cd. Cu, Mn, and Zn. Hg contents were detected N.D. ∼trace level (0.01 ppm and less) and As contents were detected N.D. ∼ 0.038 ppm but most of samples were not detected. Cd contents were detected N.D∼0.101 ppm. The results of Hg, As, Pb and Cd content showed that for all the 7 species of agricultural products studied, none have accumulated levels dangerous enough to pose health problems. The average contents of Cu were 4.356∼10.624 rpm in bean. the Mn were 4.332∼24.385 ppm in lettuce and the Zn were 4.072 ∼ 20.715 ppm in bean, respectively.

Recently, a number of research efforts have been taken to enhance interoperability and reusability of e-learning contents by developing ADL SCORM 2004 compliant contents. For useful and effective learning contents, content devlopers have to build the strategy of content sequencing in the phase of instructional design. However, many developers have difficulties in understanding the complicated specification of SCORM 2004 S&N(Sequencing&Navigation) and implementing SCORM sequencing. In this paper, we develop SCORM 2004 based best-practice sample contents utilizing SCORM sequencing and thus present a reference guide to the design and implementation of SCORM 2004 contents. It is expected that our sample contents illustrate an effective and useful application of SCORM 2004 as a de-facto e-learning standard, domestically and also internationally.

Recently, user-created video shows high increasing in production and consumption. Among these, videos records an identical subject in limited space with multi-view are coming out. Occurring main reason of this kind of video is popularization of portable camera and mobile web environment. Multi-view has studied in visually representation technique fields for point of view. Definition of multi-view has been expanded and applied to various contents authoring lately. To make user-created videos into multi-view contents can be a kind of suggestion as a user experience for new form of video consumption. In this paper, we show the possibility to make user-created videos into multi-view video content through analyzing multi-view video contents even there exist attribute differentiations. To understanding definition and attribution of multi-view classified and analyzed existing multi-view contents. To solve time axis arranging problem occurred in multi-view processing proposed audio matching method. Audio matching method organize feature extracting and comparing. To extract features is proposed MFCC that is most universally used. Comparing is proposed n by n. We proposed multi-view video contents that can consume arranged user-created video by user selection.

Relationship between the contents of ginsenosides in root and minerals (N,P,K,Ca,Mg) in leaf and root of and year Panax ginseng grown with solutions of various N,P,K levels was investigated by simple, multiple and partial regressions. In root K, N, and P in decreasing order showed significant negative correlation with each ginsenosides. In leaf K,N, and P in decreasing order showed significant positive, negative and both correlation with root ginsenosides, respectively. Relationship between K and root ginsenosides in the minus K plot did not follow that in other plots. The ratios of K,N, and P, in leaf to root in decreasing order showed positive correlations that were greater than in leaf or root. Mg was negatively while Ca was positively correlated in root but these were reverse in leaf and always nonisgnificant in both parts. Ginsenoside Rd, Re and $Rb_1$ were most affected by mineral contents. The effect of minerals on PT/PD was least.

This study was designed to observe the effects of the fish oil and some seed oils on the improvement of the fatty acid compositions of liver and brain tissue in rats. In order to induce the hypertriglyceridemia in the rats of the Sprague-Dawley, 12% coconut oil and 3% each of olive oil, lard, fish oil, perilla oil, corn oil, red pepper seed oil and evening primrose oil were administered to the rats for 4 weeks. In the fatty acid composition of liver lipid, n-3 PUFA contents were most in the fish oil and perilla oil groups of phospholipid fraction, and n-6 PUFA contents were most in the corn oil, red pepper seed oil and evening primrose oil groups of triglyceride fractions. Fatty acid composition of liver lipid fractions were influenced from the fatty acid composition of the test lipids. In the fatty acid composition of brain phospholipid, n-3 PUFA contents (8.8~17.2%) were most in the fish oil group, and n-6 PUFA (34.6~38.2%), though it contains high percentage, showed little difference between groups.

Two rice cultivars (Oryza sativa L.), Hwa-seongbyeo of Japonica type and Taebackbyeo of Indica/Japonica type, were cultivated with hydroponic culture to examine nitrogen effects on the growth responses, contents and utilizations of carbohydrates, and the ripening velocity of grains with three different N levels. Plant height and tiller number were clearly increased to 80 ppm N level compared to 40 ppm N level and then they were slightly decreased in N level of 120 ppm. Higher dry weights were appeared with 80 ppm N level than did with other N levels, showing statistically differences in both cultivars and N levels, while dry weight of roots was heavier with decreasing the N levels. Therefore, T/R ratios were not significantly different among N levels, although there was statistically differences between rice cultivars. After the flowering stage, higher water-soluble carbohydrate (WSC) and water-insoluble carbohydrate (WISC) were contained in stem compared with other parts, showing that WISC of sheath and stem, unlike WSC, was significantly different among N levels. Starch of grain, WISC, was remarkedly increased from 3.0% at just after the flowering to 52.0% and 75.0% at 15 and 30 day after the flowering, respectively, showing that lower N application had faster accumulation of starch in rice grains. N would affect the contents of carbohydrates of each tissue, and starch accumulation in rice grains.

In this research, the vegetation growth and rice taste of the liquid fertilizer applied fields (LF) were compared with those of chemical fertilizer applied fields(CF) in order to confirm the possibility of methane fermentation digested sludge as liquid fertilizer using precision agriculture and remote sensing technology. In panicle initiation stage, the vegetation growth at LF was 60%~80% of it at CF and there were significant difference of nitrogen contents between CF and LF. The estimation model of nitrogen contents was established by GNDVI (R=0.607, RMSE=$1.04\;g/m^2$, n=36, p<0.01). In heading stage, vegetation growth at LF went close to it at CF as ratio of 80%~95%. The nitrogen content estimation model was also established (R=0.650, RMSE=$1.73\;g/m^2$, n=35, p<0.01) and there were significant difference of spatial variability between LF and CF. There were not significant difference of rice taste and it's elements, when three samples, which were more than twice of standard deviation, were excepted. The protein contents estimation model using GNDVI of before harvesting (R=0.700, RMSE=0.470%, n=29, p<0.01) were more suitable to predict the protein contents at harvesting comparing with it of heading stage(R=0.610, RMSE=0.521%, n=29, p<0.01).
