The purpose of this paper is to explore the concept of the fitness and the way of the inspection in the Leadership study. Although the study of the fitness is recently increased, however, the concept recognition and the positive analysis on the inspection of the fitness isn't in the saddle and by inspecting after the operationalization, the theory and the result don't often correspond. So, This study is to help the following study and provide the conception and the problem of the analysis on the centering the fitness of the moderator and the mediation.

Operational risk is defined as the risk of loss resulting from inadequate or failed internal processes, people and systems, or external events. The advanced measurement approach proposed by Basel committee uses loss distribution approach(LDA) which quantifies operational loss based on bank's own historical data and measurement system. LDA involves two distribution fittings(frequency and severity) and then generates aggregate loss distribution by employing mathematical convolution. An objective validation for the operational risk measurement is essential because the operational risk measurement allows flexibility and subjective judgement to calculate regulatory capital. However, the methodology to verify the soundness of the operational risk measurement was not fully developed because the internal operational loss data had been extremely sparse and the modeling of extreme tail was very difficult. In this paper, we propose a methodology for the validation of operational risk measurement based on bootstrap confidence intervals of operational VaR(value at risk). We derived two methods to generate confidence intervals of operational VaR.

Cryptographic algorithm testing is performed to ensure that a specific algorithm implementation is implemented correctly and functions correctly. CMVP(Cryptographic Module Validation Program) of NIST in US is the well-known testing system that validates cryptographic modules to Federal Information Processing Standards (FIPS). There is no FIPS-approved stream cipher, and CMVP doesn't involve its validation testing procedure. In this paper we provide validation systems for three currently used light-weight stream ciphers: Bluetooth encryption algorithm E0, 3GPP encryption algorithm A5/3, and RC4 used for WEP and SSL/TLS Protocols. Moreover we describe our validation tools implemented by JAVA programing.

본 논문에서는 형식 기법을 이용하여 차세대 지능망 응용 프로토콜(INAP:Intelligent Network Application Protocool)적합성 시험 스위트를 생성하는 방법 및 IUT(Implenentation Under Test)시뮬레이터를 구축하여 시험을 수행함으로써 시험 스위트를 검증하는 방법에 관해 기술한다. SDL(Specification and Description Language)과 같은 형식 언어를 사용하여 INAP FSM(Finite State Machine)을 모델링하고 MSC(Message Sequence Chart)로 시험 목적을 기술한다. 기술된 FSM모델과 시험 목적을 검증하기 위해 모의 시험을 거치며, 검증이 완료된 후 시험 스위트로 변환이 된다. 형식 기법을 이용하여 INAP규격을 정확하게 기술할 수 있을 뿐 아니라 시험 스위트를 자동으로 생성함으로써 시간과 비용을 절감할 수 있다. 또한 생성된 시험 스위트를 시험기에 탑재하여 IUT시뮬레이터를 대상으로 시험을 수행함으로써 시험 스위트를 검증할 수 있는 방안을 제시하였다.

In order to obtain a good quality product, a proper verification of production/test facilities must be preceded before the quality conformity inspection of the product. Among the various production/test facilities, ATE is widely used in the civilian industry such as the automotive industry, aerospace industry, semiconductor industry today. In addition, ATE is actively used in the defense industry production and performance tests. This paper is the result of systematically verifying the Design Conformance of ATS which is ATE of military FM radio set using various methods. And It is expected to be a good reference at the present time when the design conformity verification procedure for ATE for military supplies is not documented.

In Basel II compliance, internal rating systems are allowed for banks to enhance the self control and the validation of the system are getting more important. The validation methods are composed of qualitative test and quantitative test, three basic standards of which are discriminatory power, stability and calibration. The aim of this article is to review the quantitative tests for calibration and find a new method for it. These methods for discrimination between forecasted PD and observed PD include binomial test, chi square test, Brier score, traffic lights approach, normal test and extended traffic lights approach. We introduce a modified extended traffic lights approach considering asset correlations.

Recently the biometric recognition technology is intensively studied and the standardization of the technology has been highly demanded for its commercialization. Currently many blometric recognition products are being developed based on the BioAPl(Biometric Application Program-ming Interface) specification. However, the reliable testing tools (or scenarios) to evaluate performance and conformance of the products are not shown yet. In this paper, a conformance testing method is presented, which verifies a biometric recognition system to meet the requirements of the BioAPl standard. Two different testing procedures are used in the proposed method. The first procedure evaluates that each functions offered in the BioAPl specification are correctly implemented and that the functions are actually used in the system. Through the Procedure, a BSP(Biometric Service Provider) system is executed on the framework of the BioAPl functions. It requires selection of parameters and prece-dent functions that should be executed first. The second procedure evaluates the abilities of module management, handling operations and ver-ification process by the analysis of the test cases. It tests the correctness of the system operation when a testing scenario is given. The proposed testing method is applied on a fingerprint verification BSP using the sample BSP provided by the BioAPl consortium. The experimental results shows the benefits of the proposed testing method.
