Plant industry is very important industry that dominate 70% of standard foreign countries construction acceptance an order woe 2004 years. Technique of plant industry is state that secure part equipment connection detailed design and construction class' competitive power. But, high added value creation among plant industry need technique elevation because available plan, basic design technology is insufficient. Therefore, high added value creation wishes to present problem of standard code and improvement direction for plant design to improve available plan, basic design technology competitive power.

This study was conducted to investigate the high-value added new products from spent hens. Spent hens were randomly designed to one of the four dietary treatments: 1) Control (commercial feed),2) T1 (commercial feed supplemented with 100 lU ${\alpha}$-tocopherol, 3) T2 (commercial feed with 10% squid liver oil and 4) T3 (commercial feed with 100 IU ${\alpha}$-tocopherol plus 10 % squid liver oil). They were fed one of the experimental diets for 15 days and slaughtered. And, also, somking of spent hens as follows : digestion in sources, boiling and somking.

The dies & molds are a very economical production tool and a high value-added product because of its mass production capability compared to other production methods. Due to the very stiff international competitiveness, the industries meet many obstacles. For the promotion of the industry, the status and the international trends of the industry are measured. The vision and strategy are driven. In Korea, large portion of dies and molds are still low value-added and make large number of tools. In order to advance this industry to the high-tech area and gain competitiveness in the global marketplaces, effective means of resource investment and strategy should be properly provided.

Interlace textured yarn was developed in order to increase weaving process efficiency. Today, interlace texturing is very useful method of manufacturing the high added value compound yarns for new synthetic fabrics. In this research, new silky type high added value compound yarns were. manufactured by interlace texturing technology and tested their properties. The object of this research is to investigate the relationship between interlace textured yarn properties and processing parameters that is air pressure, yarn tension and take-up speed. The original filament yarns used were TTD(Thick & Thin Semi-Dull) 110d/72f and SCD(Semi-Dull Cation Dyeable) 75d/36f. 27 specimens were manufactured and tested for their physical properties-nip density, tensile properties, multi-step shrinkage test and surface structure by SEM. The air pressure was main process condition to change properties of interlace textured yarns. And interlace textured process had influence on weaving preparation process, weaving, knitting and so on. It has some influence on shrinkage properties of dyeing and finishing processes.

Influence of Achyranthes japonica Nakai Extract (AJNE) on properties of pork sausages were studied in the present investigation. AJNE was added to sausages alone or in combination with ascorbic acid to obtain a comparative analysis on properties of control and ascorbic acid added-sausages. Results showed that addition of 0.05% AJNE led to a decrease in color $L^*$ and whiteness (W), and an increase in color $b^*$ of pork sausage samples (p<0.05). Although color $a^*$ of pork sausages containing AJNE was not significantly different, ascorbic acid added-sausages were highest amongst other treatments (p<0.05). Sausages containing AJNE had lower non-heme iron values and peroxide value (POV) than control sausages (p<0.05); however, high nitrosomyoglobin content was observed in AJNE added-sausages (p<0.05). Ascorbic acid led to a decrease in residual nitrite concentration of sausages (p<0.05), but no difference was found in AJNE added-sausages. Free radical scavenging analysis showed that AJNE did not affect 1,1-diphenyl -2-picrylhydrazyl (DPPH) activity of sausages, whereas ascorbic acid added-sausages showed relatively higher activity among the samples (p<0.05). Addition of AJNE had no influence on texture properties of sausages. In sensory evaluation, AJNE treatment had significant effects on color (p<0.05), but no significant effects on aroma, flavor, springiness, juiciness, and overall acceptability. In conclusion, the addition of AJNE, as a natural supplement may offer natural antioxidants for pork sausages, and appears to be particularly effective in inducing changes in non-heme iron concentration, POV value and nitrosomyglobin content.

In this study, we assessed the physicochemical and sensory characteristics of cookies containing various concentrations (0, 3, 5, 7 and 9%) of leek powder. The L values of cookies containing leek powder were significantly lower than those of the controls. The spread ratio decreased proportionally with the quantity of leek powder added to the cookie recipe. The loss rate and leavening rate of samples to which 3% and 5% leek powder was added evidenced a higher value than the samples to which 7% and 9% leek powder was added. The L value of brightness was significantly reduced when leek powder was added to the cookie recipe. The a and b values were also significantly reduced with the addition of leek powder. Hardness evidenced significantly high levels in the samples to which 3% and 5% leek powder was added. The results of our sensory evaluation evidenced significantly better appearance, flavor, color, texture and overall acceptability as compared to the 3% and 5% added samples. The observed quality characteristics of the 3% leek powder added samples and 5% leek powder added samples indicated the possibility that leek cookies might be developed.

This study was carried out in the austempering temperature and time after Ni, Mo addition in purpose of modification of impact toughness of austempered ductile irons. Addition of alloy element and austempering treatment of $900^{\circ}C$ 60 minutes followed by $300^{\circ}C$, $350^{\circ}C$ and $400^{\circ}C$ for 60 minutes, in this case impact value was increased by ideal mixed structure. But impact value was decreased when holing time is 120minutes, this is attributed to segregation and carbide precipitation from high carbon austenite. Highest impact value was obtained by $350^{\circ}C$ (Mo-addition) and $400^{\circ}C$ (Ni-addition). This phenomena was caused by presence of remained austenite. At all austempering temperature,, Ni-added specimen showed higher impact values than that of Mo-added specimen. And hardness property was affected by austempering temperature and holding time rather than amounts of alloying element.

Recently, as the importance of the interior noise in a ship cabin has risen, ship builders have becomeconcerned about the use of noise reduction panels to reduce cabin noise. The results of previous researches have been based on analytical and experimental methods using simple sandwich panels. However, panel structures are becoming more complex to improve the transmission loss. Thus, researches that analyze the transmission loss of a panel are reaching the limit of study. This paper reports on research that was performed to determine the sound transmission characteristics of multi-complex panels applicable to high value-added vessels. It presents comparisons between analytical methods and experimental results by using a mini-reverberant chamber with components of sound attenuation panels, including the core and surface materials. The sound transmission loss of multi-complex panels are also analyzed in terms of the influences of the inside perforate plates and air gap thickness on the attenuation. Finally, the multi-complex panel with the highest noise attenuation is proposed based on the analysis results and experimental results in mini-reverberant chamber, which wereverified using a real-size reverberant chamber.
