This study was investigated the mechanism of action of n-6/n-3 fatty acid ratio on the metabolic partitioning of blood glycerolipids by in vivo monitoring technique in hyperlipidemic animal model rats. The ratio of cholesteryl 14C-oleate metabolized in the liver of total glycerolipids was lower in the order of n-6/n-3 ratios of 4:1, 15:1, 30:1 and control group (p<0.05). The secretion amount of phospholipid was higher in the order of n-6/n-3 ratio 4:1, 15:1, 30:1 than the control (p<0.05). The secretion amount of triglyceride was lower in especially 4:1, in order of n-6/n-3 4:1, 15:1 and 30:1 compared with the control. The ratio of phospholipid partitioning to total glycerolipid was high in orfer of n-6/n-3 ratio 4:1, 15:1, 30:1 and control (p<0.05). The triacylglycerol partitioning (%) via liver was higher 72.97, 75.93, 78.12% in n-6/n-3 4;1, 15:1, 30:1, respectively than the control of 82.25%, according to increased n-6/n-3 (p<0.05). The phospholipid partitioning (%) was lower 25.15, 18.87, 18.15% in n-6/n-3 4;1, 15:1, 30:1, respectively, compared to control 11.04%, according to increased n-6/n-3 (p<0.05).

An embedded system is called a multi-mode embedded system if it performs multiple applications by dynamically reconfiguring the system functionality. Further, the embedded system is called a multi-mode multi-task embedded system if it additionally supports multiple tasks to be executed in a mode. In this Paper, we address a HW/SW partitioning problem, that is, HW/SW partitioning of multi-mode multi-task embedded applications with timing constraints of tasks. The objective of the optimization problem is to find a minimal total system cost of allocation/mapping of processing resources to functional modules in tasks together with a schedule that satisfies the timing constraints. The key success of solving the problem is closely related to the degree of the amount of utilization of the potential parallelism among the executions of modules. However, due to an inherently excessively large search space of the parallelism, and to make the task of schedulabilty analysis easy, the prior HW/SW partitioning methods have not been able to fully exploit the potential parallel execution of modules. To overcome the limitation, we propose a set of comprehensive HW/SW partitioning techniques which solve the three subproblems of the partitioning problem simultaneously: (1) allocation of processing resources, (2) mapping the processing resources to the modules in tasks, and (3) determining an execution schedule of modules. Specifically, based on a precise measurement on the parallel execution and schedulability of modules, we develop a stepwise refinement partitioning technique for single-mode multi-task applications. The proposed techniques is then extended to solve the HW/SW partitioning problem of multi-mode multi-task applications. From experiments with a set of real-life applications, it is shown that the proposed techniques are able to reduce the implementation cost by 19.0% and 17.0% for single- and multi-mode multi-task applications over that by the conventional method, respectively.

This paper examines how split-screen technique works to meet the goals and strategies of the narrative in the romantic comedy films which deal with love and sex. The plot of romantic comedy films aims to the union and marriage of the couple, but is structured to delay the union as much as possible through comical situations and episodes. Usually split-screen scenes are placed before plot point 2 and serve to make a laugh and humor. Besides, it helps focusing on two main characters. Comedy related to love and sex comes from information gap between two main characters which can cause a tension, double meaning of spoken words and combination of split-screen images. Michael Gordon's Pillow Talk(1959) and Peyton Reed's Down with Love(2003) are reviewed in this study.

The purpose of the present study was to investigate the mechanism of metabolic partitioning between oxidization and esterification of liver fatty acids synthesized and secreted by the liver from egg yolk-fed laboratory rats. Animals were divided into four groups and orally administered egg yolk daily for 30 days: CON (control group, 1.0 g of saline solution), T1 (1.0 g of pork belly oil), T2 (1.0 g of egg yolk), and T3 (1.0 g of pork belly oil and 1.0 g of egg yolk, alternatively each week). The accumulation rate of [¹⁴C]-labelled lipid in liver was lowest in T2 among all treatments (P<0.05). Phospholipid secretion was higher in T2 than other treatments (P<0.05). The triglycerol secretion was highest in T1 and higher in the order of CON, T3, and T2 (P<0.05). Metabolic partitioning rate of phospholipid from total glycerolipid was highest in T2, followed by T3, CON and T1 (P<0.05). The ¹⁴CO₂ production from total glycerolipid was the highest in T2 and showed a high oxidation rate compared to CON, T1, and T3 (P<0.05). Metabolic partitioning of glycerolipid from the liver decreased in triglycerol of T2 compared to CON, T1, and T3, whereas phospholipids of T2 increased (P<0.05).

The objective of this study was to investigate the effect of diets with different omega-6 (n-6) and omega-3 (n-3) fatty acid ratios (0, 1.2: 1, 8: 1, 19: 1) on mechanisms of partitioning of in vivo hepatic glycerolipid metabolism in next generation rats. Biomonitoring techniques were used in rats (jugular vein cannula were attached). The range of $^{14}CO_2$ exhaled by glycerolipid metabolism was 7.05-20.17% in the group having diet with n-6/n-3 ratio less than 8:1. It was the lowest in the control group. Total glycerolipid was the highest in the control group. For groups with different n-6/n-3 ratio, it had the following order: 19:1>8:1>1.2:1. Secreted triglyceride was decreased by 36.35%, 20.93%, and 13.72% in 1.2:1,8:1, and 19:1 groups, respectively, compared to that in the control group. The ratio of phospholipid to total glycerolipid was 1.38, 1.29, and 1.17 times higher in 1.2:1, 8:1, and 19:1 groups, respectively, compared to that in the control group. The ratio of $^{14}CO_2$ to total glycerolipid was 1.61, 1.52, and 1.29 times higher in 1.2:1, 8:1, and 19:1 groups, respectively, compared to that in the control group.

This study was conducted to evaluate roughage to concentrate ratio on the changes of productivity and metabolic profiling in milk. Six lactating Holstein cows were divided into two groups, T1 group was fed low-concentrate diet (Italian ryegrass to concentrate ratio = 8:2) and T2 group was fed high-concentrate diet (Italian ryegrass to concentrate ratio = 2:8). Milk samples were collected and its components and metabolites were analyzed by ¹H-NMR (Nuclear magnetic resonance). The result of milk components such as milk fat, milk protein, solids-not-fat, lactose and somatic cell count were not significantly different between two groups. In carbohydrate metabolites, trehalose and xylose were significantly higher (P<0.05) in T1 group, however lactose was not significantly different between two groups. In amino acid metabolites, glycine was the highest concentration however, there was no significant difference observed between two groups. Urea and methionine were significantly higher (P<0.05) in the T2 group. In lipid metabolites, carnitine, choline and O-acetylcarnitine there were no significant difference observed between the two groups. In benzoic acid metabolites, tartrate was significantly higher (P<0.05) in T2 group. In organic acid metabolites, acetate was significantly higher (P<0.05) in T1 group and fumarate was significantly higher (P<0.05) in T2 group. In the other metabolites, 3-methylxanthine was only significantly higher (P<0.05) in T2 group and riboflavin was only significantly higher (P<0.05) in T1 group. As a result, milk components were not significantly different between two groups. However, metabolites concentration in the milk was significantly different depends on roughage to concentrate ratio.

In this paper, we study on making a use of value-added services using DTV closed caption data. Note that Closed-Captioning service helps to bridge "digital divide" through extending broadcasting accessibility of a neglected class such as hearing-impaired person and foreigner. In Korea, DTV Closed Captioning standard was developed in June 2007, and Closed Captioning service should be provided by an enforcing law in all broadcasting services in April 2008. Here, we describe the method of extracting a caption data from MPEG-2 Transport Stream of ATSC-based digital TV signal and generating a caption file using the extracted caption data and time information. In addition, we present the segmentation method of broadcasting content using caption file. Experimental results show that implemented S/W tool provides the feasibility of the proposed methods and the usability of closed caption for a variety of data application service.

The effect of combinations of 8 antimicrobial agents on the growth of Streptococcus mutans and Streptococcus sobrinus was investigated with the minimum inhibitory concentration and fractional inhibitory concentration(FIC) and ${\Sigma}FIC$ index. According to the ${\Sigma}FIC$ values by. The American Society for Microbiology and Berenbaum, Approximately 34% and 82% of the combinations were synergistic respectively. Partial synergy described by Isenberg was also observed in the half of the combinations. There was a tendency for additive antimicrobial effect against cariogenic bacteria though the test results showed difference according to the applied values. It may be beneficial to use combined antimicrobial agents that have various activities against an ecosystem and metabolism of bacteria than using individual agents.
