Purpose: The purpose of this paper is to identify Six Sigma success factors and analyse the effects of Six Sigma success factors and innovation capability on innovation performance. Methods: The study build a research framework which include the variables of Six Sigma success factors, innovation capability, and innovation performance. A sample of 127 survey questionnaires is taken to test the proposal theoretical model through structural equations modeling using AMOS 20.0. Results: This study proves that there are the positive relationship between Six Sigma success factors, innovation capability, and innovation performance. It also confirms that there are the partial mediating effects of innovation capability between Six Sigma success factors and innovation performance. Conclusion: There are various factors affecting innovation performance of firms. This study provide the mechanism transformed from Sig Sigma to innovation performance.

The major aim of this study is to identify the success factors of Six Sigma Implementation methodology for the creation of Six Sigma Performance so that many firms continue to allow innovative activities. To this end, through a review of previous studies and brainstorming with expert group, three performance factors and seven success factors were derived. In order to analyze these factors, this study conducted the Analytical Hierarchy Process(AHP) with the firm``s BB and MBB who continue to deploy Six Sigma activities for over 10 years. As a result, the support and interest in management, project selection and management, and education and training is important to be analyzed. This study has its significance that it provided the selection process and framework of the important success factors of Six Sigma with firms which will continue to deploy innovative activities by finding its appropriate implementation methodology.

Objective : The purpose of this study was to evaluate the antioxidative effects of the extract of Scolopendra subspinipes which has been used mainly for detoxication in the oriental medicine and reported to have sedative action, antiinflammatory effect, antihypertensive property and immunity enhancing activity. Method : Inhibitory activities on oxygen radical generating enzymes (aldehyde oxidase and xanthine oxidase) and increasing activities on oxygen radical scavenging enzymes (superoxide dismutase, glutathione peroxidase, glutathione-S-transferase) were investigated. Furthermore, the content of glutathione in the mouse brain, DPPH radical scavenging activity and also anti-lipid peroxidative effects in vivo and in vitro were estimated. Results : The extract showed weak inhibitory effects on the activities of aldehyde oxidase and xanthine oxidase which are oxygen radical generating enzymes. The extract inhibited lipid peroxidation with 26.1% against control group at 500 mg/kg in vivo and with 11.2% against control group at 10 mg/kg in vitro in a dose-dependent manner, which means this drug may protect radical-induced cell damages. The extract showed dose-dependently the scavenging effect on DPPH radical with 24.8% activity at 10 mg/ml in vitro. The extract enhanced the activities of superoxide dismutase, glutathione peroxidase and glutathione-S-transferase, which are oxygen radical scavenging enzymes, with 28.9%, 22.3% and 23.1%, respectively at 500mg/kg in vivo. Finally, this extract strongly increased the glutathione content in the mouse barin. Conclusion : Above results indicated that Scolopendra subspinipes can be useful for the protection or treatment of some diseases caused by reactive oxygen species.

본 연구의 목적은 문화시설을 활용하여 도시재생사업을 수행한 외국의 사례를 비교ㆍ분석하고 평가하여 우리나라 도시재생사업의 발전방향을 제시해보고자 함이었다. 이러한 연구의 목적을 효율적으로 달성하기 위하여 연구대상은 도시재생사업으로 한정하고, 연구범위로서 시간적 범위는 도시재생이 사회적 이슈로 제기되기 시작한 1980년대부터 현재까지로 하였고, 공간적 범위는 한국과 유럽으로 하였으며, 내용적으로는 문화시설을 활용한 도시재생사업의 발전방안을 제시하는 것으로 설정하였다. 연구의 접근방법은 행정적 접근방법을 사용하였고, 조사방법은 문헌조사법과 인터넷조사법을 병행하였으며, 분석방법은 사례 분석법을 사용하였다. 연구결과, 첫째, 도시재생사업은 도시환경의 개선과 함께 관광객 유치에 따른 경제적 상승효과를 가져오는 것으로 나타났다. 둘째, 문화시설을 활용한 도시재생사업은 도시경쟁력을 강화함으로써 새로운 산업과 민간투자를 촉진시키는 것으로 나타났다. 셋째, 도시재생사업의 문화예술시설 확충 및 체계적 운영을 위한 제도를 구축하고 있는 것으로 나타났다. 이상과 같이 평가된 내용을 토대로 한국의 도시재생사업에 대한 발전방안을 제시하면, 첫째, ‘문화예술시설의 건립 및 운영에 관한 법률’ 제정(가칭), 둘째, 문화예술을 활용한 도지재생 모형 구축 셋째, 도시재생 거버넌스의 구축이 필요한 것으로 나타났다. This study aimed to present a direction for development of the urban regeneration project by comparing, analyzing, and evaluating cases of such projects made successful in other countries by using cultural facilities. In order to efficiently achieve this research aim, the subject of this study was limited to urban regeneration projects and the scope embraced the period from the 1980s when urban regeneration began to be raised as a social issue to the present. The contents of the study were set to present a direction for development of the urban regeneration project by using cultural facilities while spatial subjects had the Republic of Korea and Europe. Literature review and internet research were conducted as for research methods while administrative approaches were applied. As for the analytic methodology, case comparative analysis was conducted. Based on the results from analyses, establishment of (tentatively named) ‘the Act on Establishment and Operation of Cultural and Arts Facilities’, a model to construct the urban regeneration model using culture and arts, and finally, the private-public cooperation were found to be necessary.

In recent years, vehicles are changing from means of transportation to means of providing various conveniences by reflecting the needs of consumers. In response to these changes, vehicle digital technology is developing, and the installation of mobile and multi-devices in vehicles is also increasing significantly. However, the more various digital technologies in the vehicle are reflected, the more handling mobile and multi-devices while driving, which may increase the risk of traffic accidents due to distraction and carelessness. This thesis investigates the installation position of the microphone in different types of vehicles, and presents the optimal installation position of the microphone in the vehicle, which is recognized the driver's speech when the driver makes a sound while seated in the driver's seat.
