VHDL simulation requires both analysis and elaboration processes. Reducing the time taken by these processes shorten design cycles. We propose an incremental analysis and elaboration algorithm for VHDL, which minimizes the number of design units to be re-analyzed and re-elaborated after an incremental change, thereby reducing the desing cycle time. Experimental results show about four times performance improvement in analysis and 1.25 times in elaboration over the conventional method.

To investigate aerodynamic performance of high-lift devices, 2D design is the base of the success of high-lift system design for transport aircraft, which can shorten the periods of three-dimensional design and analysis. For the simulation coupled viscous and inviscous euler method (MSES) is used. In this parametric study, Gap and Overlap which can define position of flap is used as design variables and we investigale relation between angle of attack and flap position for lift enhancement.

In electrochemical glucose sensing, the enhancement of the sensitivity and the response time is essential in developing stable and reliable sensors, especially for continuous glucose monitoring. We developed a method to increase the sensitivity and to shorten the response time for the sensing upon the appropriate addition of single wall carbon nanotube onto the osmium polymer-based hydrogel electrode. Also, the background stabilization is dramatically enhanced.

In order to shorten the extraction time of saponin in ginseng products, election with Extrelut column and phase-separation methods were compared. The results obtained are as follows. 1. Saponin of ginseng products was extracted completely within 3 hours by election method with Extrelut column, and the rate of removing glucose by the column was increased with increasing glucose content in ginseng products. 2. Stirring method was superior to refluxing method for removing sugars from ginseng products, and removing rate was deceased in the order of lactose, sucrose and glucose. 3. Extraction rate of ginsenoside from ginseng extracts by the elution method was nearly same as that of phase-separation method; however, the former was much higher than the latter in the case of ginseng teas. Therefore, the elution by Extrelut column is to be improper for extraction of saponin in ginseng tea which contains much sugar. It was necessary to remove lipophilic compounds for extraction of saponin from ginseng extracts by elution with Extrelut column.

Recent the free-formed architecture is smearing as a trend with the development of the digital equipment and technologies. The development of new method based on digital technology is required for the free-formed structure,, because the conventional construction methods are limited to shorten the construction period and to ensure the construction quality. Particularly, the development of the new method for the free-formed concrete structure is important. In this study, the developed method of the T-shape lightweight steel fabricated using CNC can control the geometries of the free-formed concrete structure based on the digital design. Also, new method is effective to ensure the precision of the construction and economic than the conventional construction methods.

In this paper, a new control strategy of a series active power filter using direct compensating voltage extraction method is proposed. This control algorithm compensates harmonics, reactive power and neutral line currents which are generated by balanced or unbalanced nonlinear loads. The advantage of this method is that the compensating voltage of the series active power filter can be extracted without phase transformation. Therefore, calculation time is shorten and the control method is simple compared with conventional method as the p-q theory In addition, this control strategy was applied for the series active power filter in 3-phase 4-wire system which is widely employed in distributing electric energy to several office building and manufacturing plants. Some results obtained from the experimental model using the proposed method are presented to demonstrate and confirm its validity.

This paper proposes a novel fractal coding method for fast encoding and high compression to shorten time to take on fractal encoding by using limited search area. First. the original image is contracted respectively by half and by quarter with the scaling method and bit-plane method. And then, the corresponding domain block of the quarter-sized image which is most similar with one range block of the half-sized image is searched within the limited area in order to reduce the encoding time extremely. As the result of the evaluation, the proposed algorithm provided much shorter encoding time and better compression ratio with a little degradation of the decoded image qualify than Jacquin's method.

Current study was conducted to investigate the effect of different hanging techniques (achilles tendon, aitch bone and pelvic ligament) on variations in sarcomere length and palatability within and between muscles using thirty-four Angus steer sides. Results showed that tenderstretch(by either suspension method) resulted in longer sarcomeres for most positions within the major leg muscle than did conventional hanging method, but in some minor muscles(eg., mm. gluteus profundus, gastronemius, and gracilis) tenderstetch allowed the muscles fibres to shorten. Some tenderstretched muscles(e.g., m. gluteus profundus, 1.5 ${\mu}m$) appeared not to toughen even at very low sarcomere lengths, while others toughened at higher sarcomere lengths. The current data demonstrated that the effect of tenderstretch on the length of sarcomeres and its influence on palatability varied between muscles, Overall the difference between the two tenderstretch methods was for the aitch method to produce meat that was 3.2 units more palatable than the ligament hanging method.

Reinforced concrete works account for 40 to 50 percent of the total construction work. However, the shortage of construction workers is a problem in the delay of the construction period of reinforced concrete. The partial rebar prefabrication is one of the ways to shorten construction period. Thus, this study compared the partial rebar prefabrication and field fabrication method through work sampling. As a result, the partial rebar prefabrication showed a significant decrease in time compared to field fabrication method. As a result of this study, it is expected to be used as a reference for the efficient selection of reinforced concrete methods.
