In order to observe the effects of the fees mixed with the lard and two vegetable seed oils on the fatty acid compositions of liver and brain tissue, the oils mixed with 2.5% lard and various levels of perilla oil and evening primrose oil were administered to the male rats of the Sprague-Dawley for 4 weeks . In the fatty acid composition of liver lipid, saturated fatty acid (SFA) contents were rich in the phopholiipide and cholesteryl ester fraction. Monounsaturated fatty acid (MUFA) contents were rich in the triglyceride fraction and polyunsaturated fatty acid (PUFA) contents were rich in the phospholipid fraction. In the fatty acid composition of liver lipid fractions, according as the contents of mixed perilla oil decreased and the contents of mixed evening primrose oil increased , n -3 PUFA contents tended to decrease and n-6 PUFA contents tended to increase. 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 phospholipd, PUFA contents (40%) were rich and according as the contents of mixed evening primrose oil increased, the ratio on n-3/n-6 PUFA and eicosapentaenoid acid (EPA) /arachidonic acid (AA) tended to slightly decrease.

One-dimensional numerical model is implemented to investigate temperature variations in the mixed layer depth (MLD) with the passage of typhoons. In the model, we assume a non-divergent, infinite ocean and consider wind effects only, excluding isostatic effects (inverse barometric effects) and upwelling with vertical movement of the water column. Numerical experiments investigate the effects of typhoon tracks on temperature variations, including their dependence on vertical resolutions in the MLD and these results are compared with those in a three-dimensional primitive equation model (POM). The model reproduces features of the observed temperature variations in the MLD fairly well, and implies that wind effects, rather than isostatic effects, play a predominant role in temporal and spatial temperature variations in the MLD. After the passage of typhoons, however, the model does not reproduce well the temperature variations observed in the MLD, because a limitation of the model is its inability to reproduce events such as cyclonic eddy formation (Hong et al., 2011; Masuda and Hong, 2011). The model also shows well the so called 'rightward bias' (Price, 1981) of sea surface cooling which is the most predominant in the right hand side of typhoon's track.

Manufacturing process of porous glass by the filler method was studied. Commercial soda-lime-silicate glass powder was mixed with inorganic salt as the filler such as KCl, K2SO4, Na2SO4. Sintering shrinkages of mixed powders with the variation of sintering temperature were compared, and the effects of the fillers to shrinkages of mixed powder were increased in the order of Na2SO4${\mu}{\textrm}{m}$ of pore diameter were manufactured when the filler sizes 100~200 ${\mu}{\textrm}{m}$. The open pore volume of porous glass is determined by the quantity of filler and porous glasses having open pore volume between 30 and 70 vol% are available. Available sintering temperature range for preparation of porous glass is from the softening temperature of the glass powder to eutectic melting temperature of DTA curve of mixed powder.

Effects of temperature dependent material properties on mixed mode fracture parameters of functionally graded materials subjected to thermal loading are investigated. A domain form of the $J_k$-integral method including temperature-dependent material properties and its numerical implementation using finite element analysis is presented. Temperature and displacement fields are calculated using finite element analysis and are used to compute mixed mode stress intensity factors using the $J_k$-integral. Numerical results indicate that temperature-dependency of material properties has considerable effect on the mixed-mode stress intensity factors of cracked functionally graded structures.

Physicochemical properties and microbiological quality chanties were investigated on mixed fruit and vegetable juices (apple, carrot and cucumber) stored at 4$^{\circ}C$ without pasteurization(NT), with light piasteurization (LP; 66$^{\circ}C$, 10 sec) and with full pasteurization(FP; 90$^{\circ}C$, 60 sec). Effects of ultrafiltration (UF) on the changes during storage were also examined. pH, viscosity, a-value and b-value remained relatively constant and all samples revealed Newtonian characterisitics. Total acidity and turbidity tended to increase slightly; however, total vitamin C content and L-value slowly decreased during storage up to about 2 months. During the first 4 weeks storage, soluble solids content slowly increased and then decreased. Mold and Yeast and Bacteria were not detected in LP, UP and UF treated samples during storage studied; however, E. coli were detected after 24 days storage. No distinctive storage effects were found among samples prepared; however, ultrafiltration had a considerable effect on the color and soluble solids content of mixed fruit and vegetable juice.

In this study, an accurate 2-noded hybrid-mixed element for continuous fiber-reinforced laminated beams is newly proposed. The present element including the effect of shear deformation is based on Hellinger-Reissner variational principle, and introduces additional consistent node less degrees for displacement field interpolation in order to enhance the numerical performance. The micromechanical and lamination theory are employed in the finite element description to consider the effects of the laminate stacking sequences, material orthotropy, and fiber volume fraction, etc. The element stiffness matrix can be explicitly derived through the stationary condition and static condensation using Mathematica program. Several numerical examples confirm the accuracy of the present hybrid-mixed element and also show in detail the effects of the continuous fiber volume fraction, stacking sequences and boundary condition on the bending behavior of laminated beams.

'Burn-Out' is a kind of printing process that can create many textural effects, also high added value of the fabrics. In the previous studies, it is examined how to burn out the cellulose part of the velvet and the polyester/cellulosic fiber mixed fabric without damage of the other part and the effects of process conditions. In this study, dyeing properties of the colored burn-out printing were investigated with various conditions onto the polyester/cellulosic fiber mixed fabrics with red disperse dye. As a results, the apparent color depth (K/S) is increased with increasing of concentration of dye. The optimum treatment conditions without any shrinkage or occurrence of yellowness on the polyester ground fabrics are fixation temperature of $140^{\circ}C$ and time of 3 minutes.

Using mixed incubation of cultured endothelial cells, cultured fibroblasts, neutrophils activated with PMA and paraquat, the production of superoxide anion, $H_2O$$_2$and lipoxygenase metabolites (5-HETE and 12-HETE) of arachidonate was estimated. The results was as follows: 1. Neutrophils activated with PMA was produced superoxide anion,$H_2O_2$and lipoxygenase metabolites (5-HETE and 12-HETE) of arachidonate. 2. Fibroblasts did not alter the production of superoxide anion and $H_2O_2$ by neutrophils, it was markedly reduced by mixed incubation with endothelial cells. 3. Mixed incubation with endothelial cells significantly augmented the production of 5 or 12-HETEs, but fibroblasts did not. 4. Using mixed incubation of endothelial cells, fibroblasts, neutrophils and paraquat (50ug/m1 and 100ug/m1), the production of superoxide anion, $H_2O_2$and HETEs was significantly increased on both cells at low concentration (50ug/m1), but markedly reduced at high concentration (1001g/m1). 5. Paraquat showed concentration dependent effects on arachidonate lipoxygenase metabolism.

When the polyester/cellulosic fiber mixed fabrics were treated with sodium hydrogensulfate for burn-out printing, it is examined how the effects of process conditions as concentration of acid, fixation temperature and fixation time act onto the properties of the polyester ground fabrics. The print paste, indalca solution, was mixed with sodium hydrogensulfate and glycerine, and then screen-printed on the fabrics. The properties of the polyester ground fabrics after removing away the cellulosic fibers were investigated. The yellowness index and the breaking load of polyester ground fabrics affected by the process conditions, especially dry heat fixation temperature.

Cumulative logit random effects models are typically used to analyze longitudinal ordinal data. The random effects covariance matrix is used in the models to demonstrate both subject-specific and time variations. The covariance matrix may also be homogeneous; however, the structure of the covariance matrix is assumed to be homoscedastic and restricted because the matrix is high-dimensional and should be positive definite. To satisfy these restrictions two Cholesky decomposition methods were proposed in linear (mixed) models for the random effects precision matrix and the random effects covariance matrix, respectively: modified Cholesky and moving average Cholesky decompositions. In this paper, we use these two methods to model the random effects precision matrix and the random effects covariance matrix in cumulative logit random effects models for longitudinal ordinal data. The methods are illustrated by a lung cancer data set.
