  • 본 연구에서는 시맨틱 웹 기술을 이용해 뉴스의 동향을 분석하는 서비스를 제안한다. 뉴스 동향 분석 서비스는 뉴스들 간의 시간흐름 또는 관계들을 분석해 줄 수 있기 때문에 현재의 일반적인 뉴스검색 엔진보다 지능적인 검색 결과를 보여줄 수 있다. 이러한 서비스를 제공하기 위해서는 시간 정보에 대한 추론 기능이 필요하지만 OWL과 같은 시맨틱 웹 언어는 이를 지원하지 못하기 때문에 시간 기반 추론을 지원하기 위해 본 연구에서는 OWL을 확장한 TL-OWL(Temporal Web Ontology Language)을 제안한다.

  • It seems that the \"fuzzy boom\" which began with its applications has calmed down and fallen into decay at least in Korea. But many foreign researchers say the research related to fuzzy theory has been only running its right course. In this paper, we discuss the trend and direction of reaserch related to fuzzy theory. The search trend is obtained through the analysis of the papers of the latest 10years papers in the journals of three societies: KFIS, SOFT and IFSA.

  • The mean residual life function is the expected remaining life of an item at age $\chi$. The problem of trend change in the mean residual life is great interest in the reliability and survival analysis. In this paper we develop a new test statistic for testing whether or not the mean residual life changes its trend based on a complete sample. Monte Carlo simulations are conducted to compare the perfor mance of our test statistic with that of previously known tests.

  • The problem of trend change in the mean residual life is great Interest in the reliability and survival analysis. In this paper, a new test statistic for testing whether or not the mean residual life changes its trend Is developed. It is assumed that neither the change point nor the proportion at which the trend change occurs is known. The asymptotic null distribution of test statistic is established and asymptotic critical values of the asymptotic null distribution is obtained. Monte Carlo simulation is used to compare the proposed test with previously known tests.

  • There has been a new trend to integrate various kinds of circuits by low temperature polycrystalline silicon thin film transistor (LTPS TFT) on insulator substrates to achieve System on Panel (SOP) for flat panel displays. In this paper, we will review the trend of the SOP and discuss the utility and future possibility of the SOP.

  • The problem of trend change in the failure rate is great interest in the reliability and survival analysis. In this paper we develop a test statistic for testing whether or not the failure rate changes its trend using random censored data. The asymptotic normality of the test statistic is established. We discuss the efficiency values of loss due to censoring.

  • Because of global warming, the new environment energy policy was already announced. The role of Green-railways is increasing in the field of railway. The government announced a policy direction of science & technology basic plan. The field of railway transportation proposed various railway transportation policy and plans. In this paper, I presented technical trend analysis for railway policy and railway operation field. Technical trend analysis at home and overseas are classified into railway industry technology, railway transportation system technology, railway operation efficiency technology, railway logistics technology.
