I compare my parameter estimation methodoloay with existing method, considering both of testing effort and fault detecting rate simultaneously in software reliability modeling. Generally speaking, fault detection/removal mechanism depends on how apply previous fault detection/removal and testing effort of S/W. The fault removal efficiency makes large influence to the reliability growth, testing and removal cost in developing stage S/W. This is very useful measure during all the developing stages and much helpful for the developer to estimate debugging efficiency, and furthermore, to anticipate additional working amount.

국어 철자 검색 프로그램 세 개의 검색 능력을 비교하였다. 오류가 없는 파일, 타자시의 전형적인 오류를 포함하는 파일(자소별 오류율 1%), 그리고 광학적 문자인식 프로그램의 전형적인 오류를 포함하는 파일(자소별 오류율 $2.7{\sim}2.9%$) 등에 대하여 한글과 컴퓨터, 한국 마이크로소프트, 핸디 소프트의 워드프로세서에 도구로 포함된 철자검색 프로그램을 수행하였다. 이 세 프로그램 중에서 한글과 컴퓨터의 제품은 정방향 오판율과 오류율 낮은 파일에 대한 역방향 오판율이 낮았고 핸디 소프트의 제품은 오류율이 높은 파일에 대한 역방향 오판율이 낮았다. 세 프로그램 모두 역방향 오판율이 자소별 오류율의 10배 이상이라는 점에 있어서 심각한 문제를 안고 있는 것으로 판단된다.

The Logistic cone is studied as a most desirable for the software testing effort. Assuming that the error detection rate to the amount of testing effort spent during the testing phase is proportional to the current error content, a software-reliability growth model is formulated by a nonhomogeneous Poisson process. Using this model the method of data analysis for software reliability measurement is developed. After defining a software reliability, This paper discusses the relations between testing time and reliability and between duration following failure fixing and reliability are studied SRGM in several literatures has used the exponential curve, Railleigh curve or Weibull cure as an amount of testing effort during software testing phase. However, it might not be appropriate to represent the consumption curve for testing effort by one of already proposed curves in some software development environments. Therefore, this paper shows that a logistic testing- effort function can be adequately expressed as a software development/testing effort curve and that it gives a good predictive capability based on real failure data.

This thesis aims to study the founding process and operation of the prefectural archives of Japan and to put that knowledge to the founding regional archives in Korea. Now 28 among 47 Prefectural Governments in Japan have founded and operated the prefectural archives. While Kyoto Prefectural Library and Archives, Nagano Prefectural Museum of History, Gifu Prefectural Virtual Museum of History, The Archives of Hyogo Prefectural Government, Ibaraki Prefectural Museum of History and Hukushima Prefectural Archives are on the type of Prefectural Museum of History, the rest of them are on the type of Archives. The Prefectural Museum of History in Japan has a complex function as the museum, the library, and the archives. But the Prefectural Museum of History seems to be a sort of transient phenomenon to Archives. The reason which Prefectural Museum of History can not develop into the Archives is not so much owing to financial difficulties as lack of understanding on the function of Archives. The thesis shows founding process of each prefectural archives. Especially, the case study on the Kanagawa Prefectural Archives, Okinawa Prefectural Archives was arranged by the detailed data investigation. Comparing with other prefectures, these three prefectural archives have a system in the collection and arrangement process of current official records, paleography and many other materials, and construct records management system with institutionalizing accession, arrangement, and opening of official records by regulations, rules and so forth. But because of historical background and character in each region, the difference may exist in the founding process of three prefectural archives. Before central archival institution, National Archives of Japan, is founded, the prefectural archives have been founded at each region and they have gained relatively independent status so that decentralism in the system of managing records could be possible. And the private historical organizations had many influences on the founding process of National Archives of Japan. Of course the Japanese Archives system may have many differences from Korean regional archives. While Japan established Archives institute for itself with localism, Korea has not settled the system of self-government still. Moreover, financial difficulties on founding regional archives and lack of understanding of the Archives remained in Korea. And yet with regard to the founding regional archives in Korea, the case of operation and founding process of prefectural archives of Japan may be of great value.

This study is designed to extract sensibility words of mobile phone image and analyze the relational patterns among those words to develope a sensibility model for mobile phone design. We expected the different sensibility scale would be developed according to the case of open or closed. The 25 representative words were abstracted as a result of words collection. As a result of the factor analysis of sensibility evaluation for mobile phone, the mobile phone design image was different according to the state of folding and unfolding. In the state of folder unfolding, the first factor was named as 'cool', the second factor as 'soft' and the third factor as 'handy'. In the state of folding, the first factor was named as 'stylish', the second factor as 'variegated' and the third factor as 'hard'.
