  • The objective of this study was to determine the effects of processing method and rapeseed variety on ruminal and intestinal protein digestibility of rapeseed meal in steers. Intestinal amino acid digestibility was assessed with an in situ ruminal incubation and precision-fed rooster bioassay. In this experiment one traditional rapeseed meal sample (sample A, prepress extraction) and three double low rapeseed meal samples (sample B, prepress extraction, sample C, screw press and sample D, low temperature press) were placed in polyester bags(8 cm${\times}$12 cm) and suspended in the ventral rumen of steers for 16 h. The residues of in situ incubations were intubated to roosters. Total excreta were collected for 48 h after incubation and then desiccated and amino acid concentrations were determined. Results showed that in ruminal incubation the degradation rate of amino acid and crude protein was higher for traditional rapeseed meal sample A than for double low rapeseed meal sample B, but was much lower than for double low sample C and D. In the group of double low rapeseed meal samples, sample D processed by low temperature press had the highest degradation rate of amino acids in the rumen. For all amino acids, the digestibility of the residual protein as measured by the precision-fed rooster bioassay tended to be lower for sample B than for sample A, which had the same processing method with sample B, and in the group of double low rapeseed meals, sample B had similar digestibility of amino acid in residual protein to sample D and higher than that of sample C. However, although the total amino acid availability involving the digestibility of amino acids in the rumen and rooster bioassay of double low rapeseed meal sample D (low temperature press) was higher than those of the other three samples by 7 to 9 percent, there were no significant differences. Results indicated that processing method markedly affected ruminal and post ruminal amino acid digestibility of rapeseed meal when the temperature exceeded 110$^{\circ}C$. Rapeseed meal that had a high content of fiber was not suitable for dry heat treatment at higher temperatures or the amino acids digestibility in rumen and total availability of amino acids could be reduced. Results also suggested the variety of rapeseed meal had no significant effect on the digestibility and availability of amino acids.

  • 70년대 사식 시스템을 신문 제작에 도입한 이후 CTS(Computerized Typesetting System)에는 많은 변화와 발전이 있어 왔다. CTS는 HT(Hot Plate Type)방식에 비해 제작 시간의 단축, 레이아웃 다양화, 편집 모양의 자유로운 변경, 공해 요인의 제거등 많은 장점을 제공한다. 그러나, 신문은 경쟁 매체의 등장, 이윤 추구라는 경제 원리의 확대등 새로운상황에 직면해 있으며, 이를 교열부의 축소 및 페지를 통한 경비 절감과 신속한 지면 제작을 위한 편집자 직접 조판으로 해결하고자 한다. 본 논문은 편집자 직접 조판을 위한 기본요건과 기술 마크업에 근거한 CTS의 설계에 대하여 기술한다.

  • According as the latest printing technology is converted from analogue to digital, life cycle of a printing technology is shortened and the existent printing companies were faced always in a new technology. Specially, way of foreign countries export opened because globalization of printing market is accelerated. But, printing buyers of advanced nation require standard printing process control. fect at product process step. Emphasized in IPA technical conference for past several years tendency about graphic art color proofing and technical analysis and comparison going through Color Proofing RoundUP. These researchers have developed a color management technology. A specially developed printing technology and reference characterization data brought certain high quality elevation in a graphic art proofing technology. When excessive GCR method application supervise printing, width of color conversion necks by requiring a lot of color conversions than proofing. But, these point is lacking relatively than a lot of effects that GCR gives. Therefore, correct interests of GCR algorithm and verification step to forecast beforehand result about actuality application are positively necessary. Therefore, this research forced into input file which is applied with different levels from input to print for printing optimization that consider standard printing with eco-friendly by method to solve these problem. And experimented using manuscript who GCR level is applied as is different in each field, and analyzed the result. Also, it is verification method by step to last printing from input file that solve been the various quality who generate in actuality field through these analysis result. ICC color management confirmed printing optimization process applying GCR algorithm improved to base.

  • When it comes to current growth trend for the printing process in Asia printing market, offset printing, gravure printing and screen printing are reduced respectively -4%, -19%, -55%. In judging from the fact, the change in the printing production system from mass production on small amount to small production on mass amount is the biggest issue. For this reason, digital printing shows the significant growth. According to the increase of the growth 78% for electro photography way and 67% for ink-jet, it's not enough to catch up with digital printing which is increasing as time goes by to equip with hardware like as digital press. There's been necessary to install the BOD(Book on Demand) system which is the advanced and regular publication edit solution based on web-to-print model in the prepress, and it has made the BOD system be considered in relation to maximization of efficiency and production. Therefore, this research tries to step forward from the POD concept, which is refired to "Print along with the ordered quantities, the ordered appropriate time and the demanded place", so that it could expand the range of the printing/publishing environment using the BOD system, the order-made publication based on automatically operating template. And it tried to make the relation to digital web press on ink-jet method which is adequate to "mass production on small amount" with such advanced concept. This research also aims to use actively BOD solution model to promote the productivity of labor, and then to produce the printings across all related industries, which means to manufacture maximally the products on the shortest time at minimum place through PC equipments.

  • For the color offset printing, it starts with input of data. The past days, drum scanner or flat scanner used to input of data, but now it changes gradually into using of digital camera because digital camera become popular. The high quality digital camera saves as a data(RAW format), sRGB which have built in digital camera, or Adobe RGB format. sRGB of ICC(International Color Consortium) profile is a standard color gamut of digital camera. Distribution of color gamut in sRGB is less than Adobe RGB have a distribution in ICC profile. sRGB also can not be expressed in some specific part, because distribution of color gamut in sRGB is not able to cover all parts in ICC Profile of international standards CMYK. It is more popular to use Adobe RGB than sRGB to do high quality offset printing and software basis color setting in Europe and Japan. In spite of this data basis, there is a difficulty of doing color correction between the color proofing prints and the final prints. To see how the software color setting effects to RGB data, this thesis will use Gretag Macbeth ColorChecker 24 patch which has the most general natural color chart to compare sRGB and Adobe RGB to check the differences of color changes. It will use the several factors that came out from the process of making ICC Profile to figure out the optimum In-house profile. It also compares the differences of using matt paper and glossy paper to do best quality color proof offset printing, and how the Rendering Intent effects the proof print.
