  • IETF has proposed CNRP that is a protocol exchanging CNRP objects between server and client for resolving a common name to URIs of the desired Internet resouces. CNRP enables users to access various services via the integrated interface, to easily get the desired resources, and to reuse the results not as the data but as the information. Whereby these advantages, CNRP will be generally used for the integration of the various Internet services or the applications where the resolution of common name is needed. But, CNRP specification doesn't describes the practical implementation method for server and client. Though a few prototype systems are developed in some researches using CNRP, they are not enough to be generally used for the various Internet applications because they doesn't include all objects specified in CNRP specification or they construct systems with one server. So, this Paper proposes the practical implementation method for CNRP server/client through analyzing and solving the problems occurred when implementing them, and implements all objects specified in CNRP specification. This paper also verifies the feasibility of the proposed method by developing the prototype system of the company name resolution service using the CNRP server/client implemented in this study. The CNRP server/client implemented in this paper are used to develop various CNRP application systems.

  • CNRP(Common Name Resolution Protocol)는 일상 생활을 통하여 흔히 접할 수 있는 회사 이름, 브랜드 이름, 제품 이름, 사람 이름, 책 제목 등의 보통이름(Common Name)의 풀이(Resolution)를 통하여 원하는 웹 리소스를 얻기위해 제안된 프로토콜이다. CNRP는 클라이언트 어플리케이션과 보통이름 풀이 서비스간의 인터랙션(interaction) 절차와 인터랙션에서 사용될 CNRP 객체들에 대해 정의하고 있다. 하지만, CNRP 명세(Specification)에서는 보통이름 풀이 서비스 시스템에 관한 구현 방안에 대해서는 언급하고 있지 않다. 따라서, 본 논문에서는 사용자가 질의한 보통이름을 풀이해서 사용자가 원하는 웹 리소스의 URI를 돌려주는 CNRP 서비스의 서버와 클라이언트의 설계 및 구현 방안을 제시하고 프로토타입 시스템을 구현함으로써 그 실용 가능성을 검증하였다.

  • 웹이 빠른 속도로 증가짐에 따라 사용자들은 점차 원하는 리소스를 얻기가 힘들어지고 있다. 비록 기존의 검색엔진이 도움을 주고 있지만, 하나의 서버가 방대하고 다양한 종류의 웹 리소스들을 모두 구분해 서비스하는 것은 점차 그 한계를 드러내고 있다. 본 논문에서는 각 검색서버들이 분류화된 이름공간내에서 검색서비스를 하고 이들을 하나의 질의 인터페이스로 통합할 수 있는 방안을 제안하고, 그 시스템을 설계하고자 한다. 제안된 시스템은 XML을 사용하는 CNRP(Common Name Resolution Protocol)을 기반으로 하여 여러 검색 서버의 결과를 쉽게 통합하고, 검색된 데이터를 일반 응용프로그램에서도 사용할 수 있으며, 동적으로 생성되는 질의 인터페이스를 통해 어떠한 검색 시스템으로도 확장이 가능하다.

  • An essential step in evaluating and comparing the performance of two passive radiation dosimeter types, thermosluminescent (TLD) and optically stimulated luminescence (OSL), used by workers in environments with ionizing radiation for individual radiological monitoring and control of external exposure at various times (cumulative dose for 1 month), is to compare the measured dose accuracy, energy response, and coefficient of variation. In fact this performance study consists in determining the accuracy of both R(10) and R(0.07) which are considered as the ratios of the measured dose (Hp(10) or Hp(0.07)) to the delivered dose (Hp(10) or Hp(0.07)) for each photon energy. The validity of the results of this test is based on the acceptance limits of the ICRP and the international standard IEC-62387. The relative energy response used is normalized to the 137Cs 662 keV energy to find which energy response is closest to the ideal case, and the coefficient of variation that allows to determine the statistical fluctuation of the Hp(10) and Hp(0.07) doses. The results of the accuracy test for the OSL and TLD dosimeters are acceptable because they fall within the ICRP limits. For the energy response, the OSL performs better than the TLD for Hp(10) and Hp(0.07), and for the coefficient of variation, the OSL satisfies the requirements of ISO 62387 for both Hp(10) and Hp(0.07), while the TLD satisfies these requirements only for the measurement of Hp (0.07).
