There are very few studies on governance structure for the collaboration between HEIs and science and technology parks until today. Major activities between science parks and HEIs are R&D activities, collaborative researches, technology transfer, space provision for BIs and Technology BIs in the science parks, provision of technical, legal and financial services for start-ups and venture firms. Governance structure for the collaboration of high education institutes with science and technology parks is the handling of complexity and management of dynamic flows of collaboration between two groups. Three models on the governance structure for the collaboration are suggested in this study. The first model is a governance structure that links R&D system such as universities, public research institutes and private research institutes with industrial production cluster such as a group of companies and industrial parks. The second model is a governance structure that has four layers of hierarchy. This hierarchical governance model is composed of four levels of organizations such as central government, three actors, one center for collaboration and many individual research performers. The third model is a governance structure that networks all the stakeholders horizontally. Under this structure, governance is conducted by the network members with no separate and unique governance entity.

The effect of vitamin C on th egramoxone toxicity in the duodenal globlet cells of rats were investigated suing histochemical methods. Rats in control, gramoxone and gramoxone+vitmain C (Vt.C) group, aged 6 to 7 weeks, were fed 18% casein diet. In th egramoxone group, neutral and acid mucins of the globlet cells in villi and crypts of duodenum tended to decrease as compared with the control group. And the globle cells secreting nonsuphated mucins tended to increase in number, being usually accompanied by a decrease of the globlet cells secreting suphated mucins which are prominent in the duodenal mucosa of control group. However, the goblet cells secreting nonsuphated mucins tended to increase in the gramoxone + Vt.C group. Morphological changes of the globlet cells in the gramoxone group were noted vacuolation and demolition of globlet cells, while those changes were not significant in the gramoxone +Vt. C group. It seems to be that Vt. C has alleviating effects on the gramoxone toxicity in secretion and production of the duodenal goblet cells.

An alkaline protease producing microorganism was isolated from korean traditional Meju and identified as Scopulariopsis brevicaulis. The optimum culture condition of Scopulariopsis brevicaulis for the production of alkaline protease was as follow: 2% soluble starch, 0.2$, tryptophan, 0.1% (NH$_{4}$) $_{2}$S$_{2}$O$_{8}$ 0.2% NaHPO$_{4}$, pH 7.5, 35$\CIRC $C. The optimum pH and temperature for the enzyme activity of alkaline protease producing Scopulariopsis brevicaulis were pH 9.0 and 50$\circ $C, respectively. The enzyme was relatively stable at pH 6.0~11.0 and at temperature below 40$\circ $C. The activity of the enzyme was inhibited by Hg$^{2+}$ whereas Cu$^{2+}$ gave rather activating effects on the enzyme activity. Phenylmethanesulfonyl fluoride inhibited the enzyme activity. This result indicates that serine is very important role in this enzyme. Km value for casein was 1.2410$^{4}$ M/L, V$_{max}$ value for casein was 25.99 $\mu $g/min. This enzyme hydrolyzed casein more rapidly than the hemoglobin.

Oxidative stress has been reported to be one of causes of neuritis. This study examined antioxidative activities of methanol extracts of six amphibian species known to be medicinal animals (Rana catesbeiana, R. coreana, R. rugosa, R. dybowskii, R. nigromaculata, and Hyla japonica) and investigated their effects of inhibiting nitric oxide (NO) production and cytotoxicity on the murine macrophage RAW264.7 cells. As inflammation is closely associated with reactive oxygen species, assays on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, xanthine oxidase inhibitory activity, superoxide anion radical scavenging activity and NO scavenging activity of the extracts of the six species were performed to investigate their antioxidative activity. The results obtained were as follows; All extracts showed antioxidative activity, and the activity of R. dybowskii was the highest in comparison among those. Anti-inflammatory effects of the extracts were also examined, the five extracts except that of R. rugosa did not show cytotoxicity for RAW264.7 cells at the maximal concentration ($1,000{\mu}g\;mL^{-1}$). Selectivity index, meaning NO scavenging activity compared to cytotoxicity, showed the highest level in the extract of R. dybowskii. These results will be very useful basic data for future studies on prevention and treatment of human diseases to understand the biological roles of amphibian extracts throughout the antioxidative or anti-inflammatory pathways.

The purpose of the present study was to scrutinize computer games that can motivate elementary school students through their interactive "edutainment" effects. The types of elements in computer games that students find interesting as learning media and their impact were studied. The current status of Korean computer games, issues related to learning English, and methods to stimulate the motivation and interest in learning by elementary school students were explored. A computer game model for efficiently teaching English to elementary school students through a connection between computer games and education was suggested. In this model, overall games were designed with the focus on the integration of curriculum and content subjects related to learning activities. For games not to be biased toward entertainment and to have systemized learning steps, the games are composed of an introduction, presentation, practice, production and evaluation, in that order. The model suggested by this plan and composition make it possible to approach learning efficiently with entertaining games based on a systematic learning curriculum. As shown above, developing the model of educational computer games can be seen as an opportunity, which can provide amusement and interests and a broad learning experience as an additional learning method.

The origin as well as the culinary aspects such as ingredients, types, preparation methods of Dasik and materials and ornamental patterns of Dasik mould(다식판) are discussed and analyzed through the literature survey. 1. The origin of Dasik came from the custom of Umdha(飮茶) together with the Worship of Buddhism(숭불정책) and the abundant production of rice due to the Policy for Agricultural Development(권농정책) of the Koryo Dynasty. 2. The main ingredient of Dasik was rice flour and wheat flour and thereafter, plant materials such as Song-wha(송화), Mungbean starch flour(녹두녹말가루) and Hwang-yul(황율) were followed. Honey, sugar and syrup were used as coagulating agents. Dasik was often colored by the addition of Omija(오미자), a plant material containing red pigment. 3. Originally. Dasik mould was not used until Jeungbo-Sanlim-Kyungje. Major types of Dasik were reviewed from the literature survey. 4. The materials of Dasik mould were wood or porcelain. Their shapes and ornamental patterns were reviewed. Circular design was predominant in the wood and lettered designs were predominant in porcelain. 5. Utilization of Dasik recorded in Koryo-History(고려사) and Chosun-Wangjo Shilloc(조선왕조실록) were reviewed.

Pseudomonas syringae pv. actinidiae strains, which cause canker disease in kiwifruit, were collected from kiwifruit orchards in Korea and identified using biochemical and physiological tests. The nucleotide sequences of the 16s rDNA and 16s-23s internally transcribed spacer of the isolates were found to be Identical to those of' the pathotype strain, Kwl 1, of P syringae pv. actinidiae. Remarkably, no coding sequence for phaseolotoxin biosynthesis or phaseolotoxin- resistant ornithine carbamoyltransferase was found by PCR amplification in any of the new Korean isolates of pseudomonas syringae pv. actinidiae, although this was clearly identified in the control pathotype Kwl 1 reference strain. In contrast, three primer sets derived from the coronatine biosynthetic gene cluster and DNA from the Korean strains yielded amplified DNA fragments of the expected size. A sequence analysis of the PCR products revealed that P. syringae pv. actinidiae and the Korean strains of pv. actinidiae contain coronafncate ligase genes (cfl)with identical sequences, whereas their. corR genes exhibited 91% sequence similarity. The production of coronatine, instead of phaseolotoxin, by the Korean strains of P. syringae pv. actinidiae was confirmed by a bioassay using reference pathovars known to produce coronatine and phaseolotoxin. The genes for coronatine biosynthesis in the Korean strains of P. syringae pv. actinidiae were found to be present on plasmids.
