The advance of science and technology becomes the nerves of the development of economy and industry of our future in the regional level as well as in the national and international level. In Korea, it has been more than 10 years since local governments launched, and they are strategically fostering their specialized regional industries. Both the central government and the regional governments prepare and execute policies to foster specialized regional industries. Though there are many kinds of methods to analyze the outcomes of science and technology of region, in this paper, we measure the outcomes of science and technology of region by applying an informetric analysis on the SCIE papers and USPA patents. To seek for the regional speciality, we analyze the total national outcomes and the regional outcomes of S&T activities in Korea.

The advent of the internet has caused a number of changes in production and dissemination of science and technology information(STI). STI was mainly produced in the form of publication before the advent of the internet. The popularization of the internet, however, has induced the mass production and distribution of STI through the internet. In consequence, the importance and usefulness of on-line STI have become on a level with those of published STI. The rapid growth of quantity and quality of on-line STI forces information service organizations try their best for improving the service satisfaction. In an effort to improve the satisfaction, researchers on information management examined the classification of information resources by exploring the counterparts of bibliography and/or web information service. We examined the national standard of the classification related to science and technology and proposed a practical scheme for the classification of on-line STI resources.

This study was carried out to investigate the effects of dietary xanthophylls supplementation on pigmentation and antioxidant properties in the egg yolk. ISA Brown laying hens aged 50 weeks were fed five kinds of xanthophyll combination such as control(neither natural nor artificial xanthophylls in feed), T1(Commercial diet containing natural xanthopylls in grain + Lutein 10ppm + Capsantin 10ppm), T2(T1 + Capsanthin 65ppm), T3(T1 + Canthaxanthin 65ppm), T4(T1 + Capsanthin 10ppm + Canthaxanthin 65ppm), and T5(T1 + Capsanthin 65ppm + Canthaxanthin 10ppm). The pH values of all egg yolks were not significantly different during storage or feeding periods. CIE L$^{*}$(lightness) values of T2 ~ T5 egg yolks were lower than those of control and T1. Conversely, the CIE a$^{*}$(redness) value of T2 ~ T5 egg yolks showed significantly higher(P<0.05). Egg yolk from chicks fed xanthophylls increased CIE b$^{*}$ values. The CIE b$^{*}$(yellowness) values of T2 ~ T5 egg yolks were higher than control and T1 during storage at 37$^{\circ}C$ for 48 hours respectively. In the antioxidation experiment, dietary xanthophylls supplementation affected lipid antioxidation of egg yolk during storage. The TBARS(O.D.) of egg yolks from chicks fed xanthophylls were lower than that of control during incubation at 37$^{\circ}C$ for 10 hours. In conclusion, dietary xanthophylls supplementation influence to color difference and retardation of lipid oxidation in egg yolk.

For the taxonomic evaluaition, 15 strains of the genus Pectobacterium and Erwinia were analyzed for 16S-23S rDNA intergenic spacer regions (ISRs). These species contained two types of ISRs, large and small ISRs. Large ISRs were on the range of 474-569 bp size, and coding transfer $\textrm{RNA}^{11e}$($\textrm{tRNA}^{11e}$) and $\textrm{tRNA}^{Ala}$. Small ISRs were 354-459 bp in length and coding $\textrm{tRNA}^{Glu}$. The sequence variations of two ISRs among species and strains were very high as compared with 16S rRNA gene sequences. By phylogenetic trees on the basis of two ISRs, Pectobacterium ere differentiated into P. carotovorum-P. cactiaidum group and P. chrysanthemi group. However, the taxonomic position of E. cypripedii and E. rhapontici, which were not clear on taxonomic delineation between Pectobacterium and Erwinia, were not clearly resolved on the basis of ISRs.

This study was carried out to evaluate changes in the characteristics of the fermented pork using a Korean traditional seasonings. Biceps femoris were cut to cube(7 ${\times}$ 12 ${\times}$ 2 em) and three Korean traditional seasonings such as soybean paste(Tl), garlic paste(T2), red pepper paste(T3), were seasoned by the proportions of meat to each seasonings(l: 1), respectively. The seasoned samples were fermented at 0 $\pm$ 1 $^{\circ}C$ for 10 days. Sensory evaluation did not significantly differ between all treatments. The highest pH among treatments were shown in T2, wheres T3 showed the lowest value. The highest saccarinity was shown in T2, followed by T3. Salinity was shown to be higher in all treatments. Shear force value was the highest in T2 and T3. VBN and TBARS increased during storage. The total bacterial counts was highest of storage 21 days. E. coli. was higher in the order of T2 > T3 > TI. Lactobacilli spp. was higher in the order of T2 > T1 > T3.

The Friction spot dissimilar welding of galvanized steel/Al6061-T6 was performed to investigate the mechanical characteristics of the joints. The presence of thin film of aluminum oxide on the surface and melting of zinc in the coating, made substandard joint characteristics for dissimilar Friction spot joining(FSJ) performed with out removing the coating. Where as, for dissimilar FSJ of galvanized steel/Al6061-T6 after removing the coating, superior agitation and welding quality has been obtained for a configuration of galvanized steel as the upper plate and Al6061-T6 as lower plate. The results from tensile tests and microscopic examination for various combinations of the welding parameters have been presented.

We have investigated an optical waveguide isolator with a multimode interference section by wafer direct bonding, operating at a wavelength $1.55\;{\mu}m$. In order to fabricate the device for monolithic integration, the wafer direct bonding between a magnetic garnet material as a cladding layer and a semiconductor guiding layer has been achieved. We found that wafer direct bonding between InP and GGG $(Gd_3Ga_5O_{12})$ is effective for the integration of a waveguide optical isolator. The isolation ratio was obtained to be 2.9 dB in the device.

A five wk feeding experiment was conducted with day-old one thousand broiler chicks (Arbor Acres) to determine the effects of microbial phytase (Natuphos$^{(R)}$) supplemented to low nonphytate P (NPP) corn-soy diets. Five pens of 50 mixed sex birds each were randomly assigned to each of the four dietary treatments: T1, control diet containing normal NPP level; T2, T1-0.1% NPP+600 U of phytase/kg diet; T3, T1 - 0.2% NPP+600 U of phytase/kg diet; and T4, T1 - 0.3% NPP+600 U of phytase/kg diet. T1, T2, and T3 showed similar growth rate, feed intake, and feed efficiency, indicating that NPP level in broiler diets could be reduced by approximately 0.2% by the microbial phytase supplementation. But T4 showed significantly (p<0.05) lower weight gain than others. The phytase supplementation improved P availability resulting in low P excretion. Weight and girth of metatarsal bone were increased by phytase supplementation at low NPP diet treatments but ash contents were not significantly different. It can be concluded that NPP level of corn-soy broiler diets can be safely lowered by approximately 0.2 % by supplementing 600 U of microbial phytase/kg diet. With the adjusted level of NPP and phytase supplementation, P excretion could be reduced by 50%.
