This research addressed improvement directions and problems of regional science and technology(S&T) policies in Daegu and Gyungbuk regions in terms of 'Creative Economy' which was a new paradigm of Park Gunhye Government. Creative Economy stressed the construction of an ecosystem in regional research and development activities, and thus it was deeply associated with building a regional innovation system(RIS). There were several problems to strengthen RIS with regional S&T policies of the regions as follows: limits in meeting regional needs due to excessive attraction of central government's projects into regions; the high ratio of programs for future basic research potentials; the lack of programs assessing and coordinating the policies; and the lack of experiences and expenditure of research institutes and firm supporting organizations. Due to these problems, the role of the policies in building RIS did not seem to be effective. Therefore, the policies need to be improved through the following measures: the expansion of regional own policies focusing regional needs; the enhancement of policy coordination by shifting to systematic approach; the expansion of soft supporting programs for constructing innovation systems; and the enhancement of stability and ability of research institutes and firm supporting organizations.

The Domi Basin in the South Sea of Korea is located between the Jeju Basin and Ulleung Basins, and is characterized by several sediment sags that are interested to have formed by crustal extension. This paper aims to derive an optimized seismic data processing procedure which helps stratigraphic interpretation of the Domi Basin. In particular, our data processing flow incorporated horizon velocity analysis (HVA) and surface-relative wave equation multiple rejection (SRWEMR) to improve the quality of stack section by enhancing the continuity of reflection events and suppressing peg-leg multiples respectively. As a result of processing procedures in this study, unconformities were recognized in the stack section that defines the early and middle Miocene, Eocene-Oligocene sequences. In addition, the overall quality of the stack section was increased as essential data to investigate the evolution of the basin. The suppression of multiple resulted in the identification of the Cretaceous basement. The data processing scheme evaluated through this study is expected to improve the standardization of processing sequences for seismic data from the Domi and adjacent Sora and north-Sora Basins.

The H.264|AVC standard incorporates an intra prediction tool into inter frame coding. However, this leads to excessive amount of increase in encoding time, thus resulting in the difficulty in real-time implementation of software encoders. In this paper, we first propose an early decision on intra prediction coding and a fast intra prediction method using the characteristics of block contents and the context of neighboring block modes for the intra prediction in the inter frame coding of H.264/AVC. Basically, the proposed methods determine a skip condition on whether the $4{\times}4$ intra prediction is to be used in the inter frame coding by considering the content characteristics of each block to be encoded and the context of its neighboring blocks. The performance of our proposed methods is compared with the Joint Model reference software version 11.0 of H.264|AVC. The experimental results show that our proposed methods allow for 41.63% reduction in the total encoding time with negligible amounts of PSNR drops and bitrate increases, compared to the original Joint Model reference software version 11.0.

The objective of the In-h(High Level Architecture) have recommended by DoD(Department of Defense) is to facilitate interoperability among simulations and to promote reuse of their components. There are many legacy simulation softwares developed before the HLA becomes simulation standard. The integration of legacy simulations into federations using the HLA is an important research topic in M&S(Modeling and Simulation) area. Legacy simulation softwares of the mission critical industry such as nuclear and aerospace are generally use Fortran language. However, the reuse of those is not easy because the HLA is not support Fortran language. This paper suggests a integration method which minimizes the modification of legacy simulation software and migrates the legacy simulation software to HLA federation. Each federate participating in federation have the separated executables that communicate via a shared memory created at run-time. Two types of shared memory blocks are used for publication and subscription. Declaration block for global variables used in legacy simulation software is separated for publication and subscription and then mapped as classes of objects and interactions for the HLA FOM design. To validate the suggested method, we approached the HLA integration of legacy nuclear simulation code being used in plant design and to observe the integration results, we used the FMT(Federation Management Tool). The diagnostic information which the FTM displays showed that our method can be successfully and effectively used for a HLA federation.

A phosphate solubilizing bacterium. strain 60-2G, possessing a strong ability to solubilize insoluble phosphate was isolated from the rhizosphere of grass. On the basis of GC-FAME profile, carbon utilization pattern, and the DNA sequence of a conserved partial 16S rRNA gene, the 60-2G was identified as Enterobacter intermedium. The analysis by HPLC revealed that the strain 60-2G produced mainly gluconic and 2-ketogluconic acids with small amounts of lactic acid in broth culture medium containing hydroxyapatite. During the incubation period of the strain 60-2G in broth culture, pH of the medium decreased upto 3.8 while the soluble phosphate concentration increased. The reversed correlation between pH and soluble phosphate concentration indicated that the solubility of P was due to the produced organic acids. The sequence homology of the deduced amino acids suggested that E. intermedium 60-2G synthesized PQQ which is essential for the oxidation of glucose by glucose dehydrogenase.

Five antioxidative active substances were isolated from the EtOAc layer (20 g/56.2 g) of Korean black raspberry (Rubus coreanus Miquel) wine (11 L, black raspberry 15.7 kg fresh wt. eq.) by various column chromatography and high performance liquid chromatography (HPLC). Proton nuclear magnetic resonance ($^1H$-NMR) spectroscopy and gas chromatography Electro Ionization-Mass Spectrometry (GC-EI-MS) identified these as 4-hydroxybenzoic acid (1, 0.1 mg), 3,4-dihydroxybenzoic acid (2, 0.3 mg), 4-(2-hydroxyethyl)-phenol (3, 0.6 mg; tyrosol), pyrocatechol (4, 0.3 mg), 3,4,5-trihydroxybenzoic acid ethyl ester (5, 0.6 mg; ethyl gallate). The presence of 1 and 2 in Korean black raspberry has previously been reported. However, the presence of 3-5 in Korean black raspberry, and the identification of 1-5 from the Korean black raspberry wine have never before been reported.

Purpose : To evaluate of the surgical outcome of primary repair in anterior cruciate ligament rupture. Material & Method : Twenty-five patients underwent arthroscopic primary repair of ACL. We performed pull-out suture of ruptured ligament in 18 cases, and suture and augumentation with gracillis & semitendinosus in 7 cases. At follow up, the International Knee Documentation Committee(IKDC) scale & Lysholm score were used to grade outcome, and also the KT-2000 arthrometer was used to evaluate objective ligament laxity. Results : In analysis of IKDC scale, final evaluation group were group A in 3 cases, group B in 13 cases, group C in 9 cases. The mean value of Lysholm score was 83 points. In KT-2000 arthrometer examination, mean anterior translation was 3.9mm at 201b, 7.3mm at 30lb. The mean difference value between injured knee and uninjured knee was 1.1mm at 201b, 2.29mm at 301b. There was statistical significance in mean difference value between injured and uninjured knee. Conclusion : By analysis of clinical & objective data, we could confirm that the mid-term result of ACL suture is not satisfactory. So, we recommend that ACL reconstruction would be done in young active patient rather than suture.

"Manggaedduk" produced specially in Uiryeong province, Gyeongnam, Korea is manufactured by traditional method using rice powder, sweet azuki bean paste, and leaves of Smilax china (called as Manggae-leaf). Moisture content of leaves did not show significant differences bay salt and purified salt treatment. The content was lower as the salt concentration increased. Shear force was higher in leaf salted with purified salt at room temperature than that salted with bay salt. On the other hands, the force was more higher in the leaves salted with bay salt at low temperature ($4^{\circ}C$). The shear force was higher as the concentration of both salts used for salting solution increased. As storage period was extended, shear force of salted leaf was weakened. Whiteness (L) and yellowness (b) of leaves stored at room temperature were higher than those stored at $4^{\circ}C$, although the redness (a) of Hunter value was not significantly different between storage temperatures. Salt concentration influenced lightness and yellowness, color of salted leaves stored at $4^{\circ}C$ resulted in enhanced greenness as compared to the leaves stored at room temperature. Thus, this study investigated the optimal storage conditions, salting conditions and storage temperatures of Smilax china leaves.

This paper aims to compare the two groups of TFA in U.S. and Dream Touch For All in Korea established with the same goals: 1) goal and core value, 2) qualification and training of teachers, and 3) educational performance. As a result of the analysis, the two groups showed that they focused on the role of teachers to improve the academic achievement of the underprivileged under the goal of solving the inequality of education. However, while TFA in the United States was able to function within public education, Korea's Dream Touch For All played a complementary role in public education. In the case of the United States, it appears to be a 'quasi-open' teacher training system that allows teachers from alternative teacher groups such as TFA to be accepted, while in Korea it shows the character of 'closed teacher training system' to be. For this reason, the two groups showed differences in core value, teacher training, and operating program, and as a result, they also set different educational models.
