최근 정부는 '창조경제(Creative Economy)'를 통하여 상상력과 창의성, 과학기술에 기반한 경제 운용, 새로운 시장, 새로운 일자리 창출을 목표로 하고 있다. 이는 또한 과학기술과 ICT, 문화, 인문학 등이 융합하여 산업간 경계부분에서 창조경제의 성과를 이룩할 수 있다는 것이 선진국의 창조경제 벤치마킹에서 증명되고 있다. 특히, 여성 과학기술인이 창조형 선진국의 사례를 보면 중요한 역할을 수행하고 있다. 하지만 한국은 여성 과학기술인이 낮은 수준이고 전문적인 여성과학기술자에 대한 적극적인 지원 및 육성정책도 미흡한 것으로 알려져 있다. 또한 경제 활동 중이던 여성들은 육아와 출산 등으로 인한 경력단절, 복귀에서 겪는 어려움 때문에 30대 초 중반 여성이 경제활동에 참여하는 비율이 적다. 창조경제를 지속적으로 발전시키기 위해서는 이를 이끌어갈 여성 과학기술인의 창조적 교육과 육성, 지원에 힘을 기울여야 한다. 따라서 본고에서는 창조경제 시대의 ICT 산업정책과 여성의 역할과 경제활동 참여 현황, 그리고 창조경제시대의 여성 일자리 창출방안과 문제점을 살펴본다.

Adipogenesis is one of the cellular processes and a highly controlled program. Nowadays, inhibition of adipogenesis has received attention as an effective way to regulate obesity. In the current study, we investigated the inhibition effect of a chloroform extract of Pleurotus eryngii var. ferulae 'Beesan No. 2' (CEBT) on adipogenesis in 3T3-L1 murine preadipocytes. Pleurotus eryngii var. ferulae is one of many varieties of King oyster mushroom and has been reported to have various biological activities, including antitumor and anti-inflammation effects. Biological activities of 'Beesan No. 2', a new cultivar of Pleurotus eryngii var. ferulae, have not yet been reported. In this study, we found that CEBT suppressed adipogenesis in 3T3-L1 cells through inhibition of key adipogenic transcription factors, such as peroxisome proliferatoractivated receptor ${\gamma}$ and CCAAT/enhancer binding protein ${\alpha}$. Additionally, CEBT reduced the expression of the IRS/PI3K/Akt signaling pathway and its downstream factors, including mammalian target of rapamycin and p70S6 kinase, which stimulate adipogenesis. Furthermore, ${\beta}-catenin$, a suppressor of adipogenesis, was increased in CEBT-treated cells. These results indicate that Pleurotus eryngii var. ferulae 'Beesan No. 2' effectively inhibited adipogenesis, so this mushroom has potential as an anti-obesity food and drug.

Nanotechnology, one of the technologies that forms the core of the recent scientific innovation, is used much in our real lives. Especially products that use nano silver are being sold, with its positive characteristics resulting from the antibacterial effects of both nano materials and silver. But critiques have pointed out that nano silver diffused into everyday life too quickly as we do not have done any comprehensive research about the material, and worry that nano silver will affect the ecology adversely. Therefore, this research focuses on investigating the toxicity of silver nanoparticles first. To compare the effects of exposure to silver nanoparticles at pre-somite stage and somite stage(10 hours after fertilization), we exposed zebrafish embryos to silver nanoparticles(15, 30 ppt) during embryogenesis, and then checked the details of catalase enzyme activity. The hatch rate decreased in the silver nanoparticles exposed groups(15 and 30 ppt); furthermore, the hatched fishes had an abnormal notochord, damaged eyes and curved tail. The catalase activities of the 15 ppt exposed group at somite stage increased relative to those in the control group. Therefore, the silver nanoparticles could seriously damage the development of zebrafish embryos. Especially, exposure to silver nanoparticles at somite stage did severer damage than exposure since pre-somite stage did.

This research focuses on entrepreneurial orientation(EO) of technology spin-offs as they are expected to reduce the gap between their technology and the market. Entrepreneurial orientation is an organizational activity or process that redistributes or combines resources in an innovative way and takes risk to create new values. It helps improve the level of organizational innovation to deal with uncertainty. An empirical study was performed to analyze the EO of spin-offs established by members of university faculties and research institutes in Korea. Antecedent variables to EO are hypothesized to include public policy for university faculty members and researchers at research institutes, the relationship with incubating organizations, and the level of social networking with other firms. The EO and technological performance relationships are also hypothesized. Data from a total of 121 spin-off organizations were collected and a series of multiple regressions were performed. The performance variable included both technological performance, such as the number of newly marketed products and new technology and subjective performance, such as the level of satisfaction with sales amount and profitability. Several important conclusions were drawn from this study. First, while government policy is not related to EO, the policy of a university or a research institute has a significant effect on the level of innovativeness. Second, a high percentage of human resources applied at the incubating organization results in a negative effect on risk taking. The level of cooperation with the incubating organization too is not related to Entrepreneurial Orientation. Third, the intensity of cooperative networking with other firms has a significant effect on risk-taking. Network relationship with government related organizations is not related to Entrepreneurial Orientation. This study analyzes the importance and role of policy of the university and research institute and networking with other firms to improve EO. It also suggests that a high composition of human resources at the incubating organization has a negative relationship with EO.

South Korea opened Incheon international airport(IIA) in march 29, 2001, with high expectations of becoming the distribution hub of Northeast Asia and aiming at a world best air hub. IIA compares quite well with any other leading airports in the world in it's facilities for the movement of people and vehicles. However, with the sequence of events following the September, 2001. terrorist attack and the war in Iraq, South Korea, an ally of the US, cannot be considered a safe haven from terrorism. At a point in time when national security is given utmost importance, it is necessary to reevaluate the security of airports, because international terrorism can only occur via air and seaports. Nowadays all the countries of the world have entered into competition for their national interests and innovation of their images. with the increasing role of international airports also comes an increased likelihood as a terrorist target, because it can affect so many people and countries. From the condition of current international terrorism, we can realize that our IIA is not completely safe from a terrorist attack. The major part of counterterrorism is event control process. It's very important for quickly saves an accident and rescues a life of person, In addition for the normalization which the airport operation is prompt. In conclusion, we should secure the legal responsibility and establish and establish a system under which we can work actively in order to implement counter terror activities from being taken an airport.

DC23, a triazolothione resorcinol analogue, is known to inhibit heat shock protein 90 and pyruvate dehydrogenase kinase which are up-regulated in cancer and diabetes, respectively. This study was performed to elucidate the metabolism of DC23 in human liver microsomes (HLMs). HLMs incubated with DC23 in the presence of uridine 5'-diphosphoglucuronic acid (UDPGA) and/or ${\beta}$-nicotinamide adenine dinucleotide phosphate (NADPH) resulted in the formation of four metabolites, M1-M4. M1 was identified as DC23-N-Oxide, on the basis of LC-MS/MS analysis. DC23 was further metabolized to its glucuronide conjugates (M2, M3, and M4). In vitro metabolic stability studies conducted with DC23 in HLMs revealed significant glucuronide conjugation with a $t_{1/2}$ value of 1.3 min. The inhibitory potency of DC23 on five human cytochrome P450s was also investigated in HLMs. In these experiments, DC23 inhibited CYP2C9-mediated tolbutamide hydroxylase activity with an $IC_{50}$ value of $8.7{\mu}M$, which could have implications for drug interactions.
