The reliability guarantee insurance policy for parts and materials was introduced to the market in 2003. This policy indemnifies manufactures of products for the repair/failure costs, recall expenses of products and business interruption losses found to be defective by users or demand companies during the terms of guarantee and after the user acquired physical possession of the product. In this paper, owing to the nature of the policy, we propose a new rate-making system considering the type of product and industry, quality control circumstances, record of guarantee performance, and exposure.

In this paper, overdetermined method is used for high resolution spectral estimation in case of short data record length. To reduce the computational effort and to obtain recursive form of estimation algorithm, we modify data matrix to have near-Toeplitz structure. Then, new recursive algorithm is derived in the form of fast Kalman algorithm. Two stage procedure is used for the estimation of ARMA parameters. First AR parameters are estimated by using overdetermined modified Yule-walker equation, and then MA parameters are implicitly estimated by estimating numerator spectral coefficients(NS).

In this paper, two species of the shore fly belonging to the genus Ochthera Latreille are newly reported from Korea: Ochthera circularis Cresson and O. japonica Clausen. A key to Korean species and diagnoses are given. Photographs on external features and illustrations of male genitalic structures are also provided.

Distributed Ledger Technology (DLT) refers to a process and related technologies that enable a person to safely suggest, verify, and record state changes (usually updates) to synchronize ledgers distributed across network nodes. DLTs are becoming increasingly important as data management requirements evolve. Therefore, they need to understand the current state of standards (such as distributed storage and access technologies) to address future requirements. This paper provides ITU-T FG-DLT standard activities, such as standardization ization trends, use cases, reference architectures, platform evaluation criteria and future prospects.

Since 2010, issues for data sharing and data exchanging in hospital information systems have been emerged. In order to solve the issues, standards should be applied to develop the systems and there should be no ambiguities between terminologies in the systems. In this paper, the terminology mapping system for narrative clinical records was implemented. The term mapping precision was 83.4%. This system could help to upgrade the text based clinical system and it would be expected to support for high quality clinical services.

NAPTR(Naming Authority Pointer) is a type of resource record specified IETF RFC 2915. NAPTR enables to register various services in tile domain name systems and thus Provides a way to discover services available on specific hosts. This paper describes the design and implementation of a proxy DNS system aimed at supporting NAPTRS. The goal of this work is to study on the feasibility of the service discovery registered in DNS via NAPTR records. This research result can be applied to service discovery in the resource information management for high performance GRID environments as well as to implement generic ENUM services

Generalized Pareto distribution play an important role in reliability, extreme value theory, and other branches of applied probability and statistics. This family of distribution includes exponential distribution, Pareto or Lomax distribution. In this paper, we established exact expressions and recurrence relations satised by the quotient moments of generalized order statistics for a generalized Pareto distribution. Further the results for quotient moments of order statistics and records are deduced from the relations obtained and a theorem for characterizing this distribution is presented.

In this paper, a system to measure treeing degradation phenomena in organic insulating materials, using an image sensor, is discussed. Using an image processing technique, tree features immediately after tree initiation as well as changes in the configuration of the tree were measured. which up to now have been extremely difficult to observe by conventional visual methods. As a result, it was possible to record the image of tree propagation immediately after its first appearance, and to describe the specific characteristics of tree growth in terms of the length, the degraded area and the sequential images.
