부정 내적 공간에서의$H^\infty$ 필터의 일반화를 통한 분산 $H^\infty$ 필터의 설계
김경근,진승희,윤태성,박진배,Kim, Gyeong-Geun,Jin, Seung-Hui,Yun, Tae-Seong,Park, Jin-Bae 대한전기학회 1999 전기학회논문지A Vol.48 No.6
We design the robust and inherently fault tolerant decetralized$$H^infty$$ filter for the multisensor state estimation problem when there are insufficient priori informations on the statistical properties of external disturbances. For developing the proposed algorithm, an alternative form of suboptimal$$H^infty$$ filter equations are formulated by applying an alternative form of Kalman filter equations to the indefinite inner product space state model of suboptimal$$H^infty$$ filtering problems. The decentralized$$H^infty$$ filter that consists of local and central fusion filters can be designed effciently using the proposed alternative$$H^infty$$ filiter gain equations. The proposed decentralized$$H^infty$$ filter is robust against un-known external disturbances since it bounds the maximum energy gain from the external disturbances to the estimation errors under the prescribed level$$r^2$$ in both local and central fusion filters and is also fault tolerant due to its inherent redundancy. In addition, the central fusion equations between the global and local data can reduce the unnecessary calculation burden effectively. Computer simulations are made to ceritfy the robustness and fault tolerance of the proposed algorithm.

한국의 벤처캐피탈은 투자규모가 세계적인 수준이나 창업초기단계 벤처기업에 대한 투자가 미흡하고 첨단기술 분야 및 수도권에 투자가 집중된 데다 신규상장 및 M&A 시장의 높은 진입장벽 등으로 벤처캐피탈의 투자자금 회수 등이 어려운 상황이다. 첨단기술 벤처기업의 경우 투자자와 벤처기업간 정보의 비대칭성으로 투자자금 조달에 어려움을 겪을 수 있으나 벤처금융 선진국은 정부 자금지원시 시장과 민간투자자와의 연계, 해외 저명 벤처캐피탈사와의 공동투자 유도 등 다양한 유인설계(incentive mechanism design)를 통해 동 문제를 해결하고 있다. 이러한 점들을 감안하여 우리 정부 및 지자체는 민간부문과의 공동펀드 확대, 지역별로 특화된 매칭펀드 조성, M&A 등 벤처캐피탈사의 출구경로 다양화 등을 통해 창업벤처생태계를 개선하는 데 주력할 필요가 있으며, 벤처캐피탈사도 외국 벤처캐피탈사와의 공동투자 등을 통해 투자대상 기업선정 및 가치증대 활동에 노력을 경주할 필요가 있다. Though South Korea has world-class volume of Venture Capital Investment, as a share of GDP, early stage venture investments are still short, and investments are concentrated in high technology area and Capital area. Because of the high barriers to entry of the new IPO and M&A market, the venture capital companies undergo difficulties in profit. High-tech ventures face difficulties in raising money from outside investors due to information asymmetry between venture investors and venture companies. To resolve these problems, developed countries's government make a co-funding investment scheme with private sectors and design incentive mechanism such as receiving knowledge of the reputable investors' joint venture. Korean central and local government can benchmark those of things. For example, the expansion of the investment volume with private sector, region-specific matching fund and venture capital's exit path diversification such as M&A through the establishment of a business venture eco-system. At the same time, venture companies are to make an efforts to enhance the ability of screening for venture companies and the value for investment activities through a joint venture investments.

In the diagnostic radiology of the nasal bone disorder, there are various techniques for the general radiography of the nasal bone projection, but the lateral bone facets are not well demonstrated. So to solve these problems, we manufactured an aid device for the nasal bone lataral view. A nasal bone lateral aid device designed fabricated and applied to radiography has given : 1. The clean image of anatomical mechanism and facilitated in positioning. 2. Time saving in radiography. 3. We gained accurate image better than without aid device.

The examination of abdominal organs such as stomach, pancreas, liver and kidney have been made by radiologic studies using contrast media and radio-isotope scan before, but today the utilization of computed tomography and ultrasound is increasing. The computed tomography is not available for the examination of infants in growing periods or pregnant women, for there is a large radiation hazard to the patient. Despite its merits of harmlessness, ultrasound has many limitations in observing the abdominal organs below the gas-filled stomach and intestine, because ultrasound cannot penetrate air and bone on account of its physical characteristics. Livers and gall bladders can be observed with ultrasound with relative success but highly sophisticated skills ara required to scan the pancreas which is located between the stomach and the duodenum. Authors scanned experimental ultrasonic examination. Sonic images obtained in each position after ingestion of water were compared with the general technique. The semi erect (20˚) ingestion water gastro window technique showed further improvement in 10 patients of pancreatic study examization. Using general technique, non visualization of the tail of pancreas occured. In contrast, with semi-erect(20˚) gastro window technique produced improved visualization.

Using a sample from Seoul Education Longitudinal Survey (SELS), this study explores determinants of multicultural acceptability of elementary, middle, and high school students using the ordinal regression analysis method. The results show that students who are considerate of others, respect the rights of others, and hold egalitarian values tend to have a higher level of multicultural acceptability. In addition, active participation in sports activities and a strong sense of self-efficacy are also closely related with multicultural attitudes. These findings imply that building students’ character and social skills is one of the most important and effective ways to instill in them the appropriate attitudes for living in a multicultural society. In light of these findings, this study suggests that long-term multicultural education programs, rather than short-term programs expecting immediate results, are needed from an early age in order to realize the vision of a socially cohesive multicultural society. 본 연구는 서울교육종단연구 1-2차년도 데이터를 사용하여 초중등학생의 다문화 수용성에 영향을 미치는 요인을 분석하기 위해 수행되었다. 이를 위해 초등학교 5학년, 중학교 2학년, 고등학교 2학년 학생들을 대상으로 서열회귀분석(ordinal regression analysis)을 실시한 결과, 학생들이 타 인종을 개방적이고 관용적인 태도로 받아들이는 데는 타인을 배려하고 타인의 권리를 존중하는 태도, 평등주의 성향, 자아효능감이 중요한 영향을 미치는 것으로 파악되었다. 또한 스포츠 활동에 적극적으로 참여하는 학생일수록 다문화 수용성이 높은 것으로 확인되었다. 이 같은 결과는 우리 학생들이 다문화사회에서 소수집단 구성원들과 더불어 살아가는 태도를 내면화하는 데는 기본적 인성과 사회성을 함양하는 것이 가장 중요하고도 실효성 있는 방안이 될 수 있음을 시사한다. 이를 근거로 다수집단과 소수집단이 서로 어울려 공존하는 다문화사회를 구현하기 위해서는 단기적인 견지에서 계몽적인 교육프로그램을 시행하는 데 급급하기보다는 좀 더 장기적인 관점에서 어린 시절부터 다양한 교육적 경험을 통해 더불어 사는 능력을 내면화시키는 것이 중요하다는 점을 제언하였다.
