  • 전통적인 디지털 박물관 시스템은 전시를 조직화하는 단순한 기능에 촛점을 두고 있으며 설계 패턴은 전시 항목들에 기반을 두고 있다. 이것의 생명주기는 직선적이고 피드백과 재사용성이 부족하여 생명 주기에서 지식 처리를 다루는 것에 대해서는 관심을 가지지 않고 있다. 하지만 현대 디지털 박물관은 급진적으로 증가하는 정보를 다루어야 하고, 디지털 감상, E-학습과 관련 연구를 위해 통합된 기능을 제공해야 한다. 이러한 요구사항들은 디지털 박물관에서 객체들이 고수준으로 추상화되고, 생명주기도 반복적이며 재사용이 가능하도록 요구하고 있다. 그러므로 체계적으로 통합된 지식처리 과정들이 디지털 박물관에서 정보시스템을 다루기 위해서 절대적으로 필요하게 되었다. 본 논문에서는 현대 디지털 박물관 시스템에서 새로운 생명주기를 제안한다. 지식 흐름(knowledge flow)은 디지털 박물관 생명주기에 걸쳐서 모든 정보 흐름으로부터 고수준으로 추상화된 객체이다. 지식 흐름을 따라가게 되면 이 특별한 생명주기는 정의된 시금석으로서 다차원의 분수 모델(Fountain Model)과 비슷하며, 이 생명주기에서 지식처리 과정은 각 차원에서 다른 강조점을 지닌 계층으로 잘 나누어진다. 또한 분산된 지식 처리 절차를 체계적이고 재사용할 수 있도록 통합하기 위한 지식 기반 소프트웨어 공학 접근방법을 제공한다.

  • This article attempted to apply the methodology of film acting as a performance oriented towards socio-cultural meaning to Min-sik Choi's acting. Specifically, the relationship between the body, the face, the audio, the direction and the attitude toward film technology mentioned in the interview dictation of actor Choi Min-sik was analyzed. In conclusion, Min-sik Choi's acting cannot be defined only by method acting, but implies or integrates the typical or avant-garde acting theories such as Stanislavsky, Strasberg, Mayerhold, Brecht and Grotovski. Above all, it is the presentation that expresses the flow of life through movement suggested by S. Kracauer. The feeling of compassion that Choi Min-sik himself emphasizes is in contact with the essence of the film that reproduces the flow of life, and it expands to an intended screen performance with a certain purpose. The screen performance that can be compressed with compassion and the flow of life is expressed by Min-sik Choi's various personas. His persona, transcending good and evil, reflects the present of Korean society.

  • 생물은 자기 복제를 통한 생장이나 생명유지를 위해 에너지를 필요로 한다. 화학영양생물은 화학에너지를 발효 혹은 호흡을 통해 생물학적 에너지로 전환시키며, 광영양생물은 광합성 작용을 통해 광에너지를 이용한다. 발효, 호흡, 광합성은 모두 산화-환원 반응을 통해 이루어진다. 생물의 모든 에너지 전환반응은 산화-환원 반응, 즉 전자의 흐름으로 이루어지며 생명현상이 에너지를 필요로 하기 때문에 생명현상은 전자의 흐름으로 이루어진다고 할 수 있다. 모든 생물이 에너지 전환 반응에 산화-환원 반응을 이용한다는 말은 생물이 많은 종류의 산화-환원 효소를 보유하고 있다는 뜻이며, 실제 많은 종류의 산화-환원 효소가 발견되고 연구되었다.

  • A carbon felt electrode was prepared using ozone and ammonia sequential treatment and applied as an electrode for a vanadium redox flow battery (VRFB). The physical and electrochemical analyses demonstrate that the oxygen groups facilitate nitrogen doping in the carbon felt. Carbon felt (J5O3+NH3), which was subjected to ammonia heat treatment after ozone treatment, showed higher oxygen and nitrogen contents than carbon felt (J5NH3+O3), which was subjected to ammonia heat treatment first and then ozone treatment. From the charging/discharging of VRFB, the J5O3+NH3 carbon felt electrode showed 14.4 Ah/L discharge capacity at a current density of 150 mA /cm2, which was 15% and 33% higher than that of J5NH3+O3 and non-activated carbon felt (J5), respectively. These results show that ozone and ammonia sequential treatment is an effective carbon felt activation method to increase the performance of the vanadium redox flow battery.

  • Drawing on a case of the construction of high-tech medical complexes, this study demonstrates the process of policy formuation. Beause the construction of high-tech medical complexes involves various analytic elements, and changes of political, economic and social environment, Kingdon's Policy Stream Framework is employed for analysis. The analysis ranges from the embarkment of the Presidential Committee on Healthcare Industry Innovation (PCHII) in August, 2005, to the enactment of High-tech Medical Complex Special Act in March, 2008. The analysis illuminates that policy formulation from agenda setting to enactment in the area of biomedical industry involves multiple factors and policy streams. An enactment of policy agenda particularly depends on the roles of multiple stakeholders as welll as policy leaders.

  • In this study, nitrogen doped carbon felt was prepared by pyrolysis of urea at high temperature and applied as an electrode for vanadium redox flow cell. Urea is easier to handle than ammonia and forms $NH_2$ radicals at higher temperatures, creating a nitrogen functional group on the carbon surface and acting as an active site in the vanadium redox reaction. Therefore, the discharge capacity of activated carbon felt electrodes using urea was 14.9 Ah/L at a current density of $150mA/cm^2$, which is 23% and 187% higher than OGF and GF, respectively. These results show the possibility that activated carbon felt electrode using urea can be used as electrode material for redox flow battery.

  • The proliferation of bioinformatics in modern biology marks a modern revolution in science that promises to influence science education at all levels. This study analyzed the contents of standards in the 7th and 2007 and 2009 revised high school biology curricula and compared the contents, amount and the presentation styles of bioinformatics with those of biotechnology in biology textbooks. In result, first of all, there are some vague expressions about biotechnology and bioinformatics in the 7th and 2007 revised curriculum. There is a clear expression about biotechnology in 'life science I' and 'advanced biology' of 2009 revised curriculum. Second, more biotechnology is introduced than bioinformatics in 'science', 'biology I', 'biology II', 'life science I' textbooks. Third, in 'biology for high class' textbook, amount of biotechnology contents in the 2007 revised curriculum didn't increase. An more effort to introduce bioinformatics to science high school student is needed according to revising curricula.
