Recently, accumulation of technology, transfer, absorption, and commercialization is being significantly recognized as a key factor for sustainable growth of the 21st century global economy. The government established "Technology Transfer and Commercialization Promotion Act" In order that the technology developed at public research institutions can be transferred to the private sector and commercialized; the technology developed in the private sector can be traded and commercialized. Also, the Article 14 of "Technology Transfer and Commercialization Promotion Act" is concerning technology transfer agents' registration, promotion, and support: it introduced the special status system of technology transfer agents and the government registers, manages, and supervises it. In most developed countries, the technology transfer agency is transferred to the private sector and it is referred as a technology transfer agent or technology broker. In the domestic market, despite the introduction of the above special status system and the building a various organization and transfer medium system for boosting the market's revitalization, some problems occurred; because the registration system of a technology transfer agent and legal basis and system about its following-up control fall short. For example, recently technology transfer-related performance exemption has brought the activation of technology transfer agent's registration, but there was the limit of selecting the expert above a certain level. Therefore, some countermeasures for this are urgent, In addition, through a compulsory training completion system before the technology trade agent registration is prepared, a short period of curriculum was not sufficient to provide applicants various specialized knowledge. In this research, it is considered about the reform of technology transfer agent through its comparative study in China and Korea. Some improvements are suggested for expanding the market of technology transfer commercialization, assuring the agents' service and strengthening the competitiveness.

This study generalized and systemized the unit-project items of 176 project districts for the rural village comprehensive development projects (RVCDP). This paper surveyed opinions of III answerers (7 specialists, 43 agents of Korea Rural Community corporation, and 61 agents of local government of cities and counties) in order to determine the classification system and their corresponding weighting values of the project items using analytic hierarchy process (AHP) method. From the results extracted by project plans of 176 project districts for 5 years from 2004 to 2008, this study decided a hierarchical system for unit-project items of RVCDP by AHP method, which consisted of three steps: 4 items for 1st step, 13 items for 2nd step, and 52 items for 3rd step. The first step contains 4 items of Strength of Rural-urban Exchange & Regional Capability (RURC), Green-income Infrastructure & Facility (GIF), Culture-health-welfare Facility, and Eco-environment & Landscape facility (ELF). In the survey of weighting values with AHP method, the analysis result for the first step showed that in opinion of specialists, GIF is more important than the others while in opinion of the other agents, RURC is more important. In the second step, Product Facility is more important in the specialists, whereas Strength of Resident Capability is the most important in the other agents. Analyzed unit project items as the third step, all answerers evaluated that the Education and Excursion for Rural Resident Capability has the highest weighting values.

In order to improve organizational performance, organizations should make a knowledge management system to share, distribute, and create related knowledge effectively in the operational process. It is not too much to say that organizational performance depends on the level of network and networking for the use of knowledge among the agents. Theoretically, a web portal is known as a useful instrument not only to link among the actors who have a specific interest and purpose but also to promote social networking which creates new knowledge relevant to user's environment. In the context, this article explored policy implications of building and operating government portals by analysing the efficacy of the "Innovative Portal", which the Korean government had opened to diffuse its innovation activities and to improve organizational innovation capacities in 2005, in innovation process from the knowledge management perspective. In particular, this study tried to identify how did the "Innovation Portal"influence network and networking of innovation knowledge using hyperlink network analysis method.

Distribution of foodborne E. coli strains, antimicrobial resistant genes and antimicrobial susceptibility have been carried out on E. coli isolated from commercial and cooked foods distributed food in Seoul. Of total 1,313 samples, fifty samples(3.8%) were found E. coli that included one of the ETEC and EPEC, respectively. The serotype of ETEC in seasoning raw meat was E. coli O26 and produced Verotoxin 2. Fifty percentage of total isolates were susceptible to all antimicrobial agents. Specially, there were ampicillin(36%), amoxicillin/clavulanic acid(32%) and tetracycline(22%) etc. Resistant gene (tetB) were found in four tetracycline resistant E. coli strains, and TEM gene was found in one ampicillin resistant E. coli isolate.

Background: Despite the proven benefits of dexamethasone in hospitalized coronavirus disease 2019 (COVID-19) patients, the optimum time for the administration of dexamethasone is unknown. We investigated the progression of COVID-19 pneumonia based on the timing of dexamethasone administration. Methods: A single-center, retrospective cohort study based on medical record reviews was conducted between June 10 and September 21, 2020. We compared the risk of severe COVID-19, defined as the use of a high-flow nasal cannula or a mechanical ventilator, between groups that received dexamethasone either within 24 hours of hypoxemia (early dexamethasone group) or 24 hours after hypoxemia (late dexamethasone group). Hypoxemia was defined as room-air SpO₂ <90%. Results: Among 59 patients treated with dexamethasone for COVID-19 pneumonia, 30 were in the early dexamethasone group and 29 were in the late dexamethasone group. There was no significant difference in baseline characteristics, the time interval from symptom onset to diagnosis or hospitalization, or the use of antiviral or antibacterial agents between the two groups. The early dexamethasone group showed a significantly lower rate of severe COVID-19 compared to the control group (75.9% vs. 40.0%, p=0.012). Further, the early dexamethasone group showed a significantly shorter total duration of oxygen supplementation (10.45 days vs. 21.61 days, p=0.003) and length of stay in the hospital (19.76 days vs. 27.21 days, p=0.013). However, extracorporeal membrane oxygenation and in-hospital mortality rates were not significantly different between the two groups. Conclusion: Early administration of dexamethasone may prevent the progression of COVID-19 to a severe disease, without increased mortality.

This paper evaluates the governance of the Andong International Mask Dance Festival. The evaluation focuses on mutual cross-assessment of agents engaging in governance relating to four elements: social justification, reliability, professionalism and transparency. Governance based on co-operative partnership was the essential factor leading to the mask festival's success. Governance of the Andong International Mask Dance Festival in 2011 was privately initiated governance having horizontal and open partnership among festival specialists, civil society organizations, regional business organizations, volunteers and local government, with the Andong Festival Tourism Foundation as the central figure. Three of governance elements were successfully carried through; the exception was transparency. The agents who gave more positive evaluations were those who played leading roles in planning and conducting events, as well as in assessing those events. The reasons for positively assessing the elements are the significance of the festival and the guarantee of agents' participation in social justification; the ability of agents, as well as cognitional and institutional trust in reliability; expert knowledge, capacity to suggest alternatives and duality of business in professionalism; and effective communication, the guarantee of opening of information and information sharing in transparency. To improve the effectiveness of governance, the system for allowing passive agents to contribute usefully should be strengthened. Mutual communication and sharing of information among agents, as well as between agents and residents, also should be more strongly reinforced.

The central nervous system depressant effect of xylazine and xylazine-ketamine was studied in chicken and mice. Intraperitoneal injection of xylazine(1~30 mg/kg) and xylazine(1~30 mg/kg)-ketamine(100 mg/kg) induced a loss of the righting reflex in chicken and mice, respectively. These effects of xylazine were dose-dependent. The results obtained were as follows; 1. The effect of xylazine-induced depression was antagonized by adrenergic antagonists having ${\alpha}_2$-blocking activity(yohimbine, tolazoline, piperoxan and phentolamine). 2. Yohimbine was most effective in the reduction of the CNS depression by xylazine. 3. Phenoxybenzamine and prazosin did not reduced CNS depression by xylazine in both species. 4. Labetalol (${\alpha}_1$, ${\beta}_1$-adrenergic antagonist) and propranolol(${\beta}$-adrenergic blocking agent) were not effective in reducing xylazine induced depression. 5. Cholinergic blocking agents (atropine and mecamylamine), a dopaminergic antagonist (Haloperidol), a histamine $H_1$-antagonist(chlorpheniramine), a histamine $H_2$-antagonist(cimetidine), a serotonergic-histamine $H_1$ antagonist(cyproheptadine) were not effective in reducing xylazine-induced depression. 6. Xylazine-induced depression is mediated by ${\alpha}_2$-adrenergic receptors and appears not to be involved in cholinergic, dopaminergic, serotonergic or histaminergic pathways.
