The latest biometric field have marched fast with security technology of IT. As importance of present biometrics is realized, internal and external biometrics software market is trend that is soaring. Accordingly, high reliability of biometric software and request of high quality software are enlarged. Evaluation items and criteria must be established for biometric software quality assurance. In this paper, we development the evaluation module for biometric software test based on ISO/IEC 12119 that is the standard about software quality requirement and test, and ISO/IEC 9126 that is standard about evaluation of software product, and ISO/IEC 14598-6 that is the standard about construction of the evaluation module. Constituents of biometric software products(product descriptor, user document program and data) is subject to the quality evaluation module that we developed in this paper, we can expect improvement in the quality of software by using with a standard such as ISO/IEC 9126-3 that can be used in software development process.

KRISS-V, a V-band millimeter-wave source module for a primary RF power standard and calibration system developed by the Korea Research Institute of Standards and Science is here presented. The output power of KRISS-V is several times higher than that of commercial amplifier/multiplier chains and is highly stable (the standard deviations of output power are less than 0.01% in the worst case). The spectral purity of KRISS-V is high enough to consider it a single-tone signal generator. We also added programmable attenuation capability to KRISS-V for remote power control. Moreover, the in-house source module is cost-effective and adaptable to various measurement schemes. The structure of the model as well as detailed component information are introduced so that it can be reproduced.

The strategy of open architecture control system intends to integrate manufacturing components on a single platform, so that a particular component can be easily added and/or replaced. Therefore, the control scheme is neither hardware dependent nor software dependent. In this paper a modular and object oriented approach for the open architecture structure of control systems is invesigated. A standard reference model for genetic manufacturer system, which consists of three modules; hardware module, operating system module, and application software module, is first proposed. Then a standard reference model for open architecture robot control system is suggested.

This paper is intended to provide a method to design control software for the TCMS, train control and monitoring system. The TCMS with this control software will be applied KOREA Standard EMU. The control software is designed by SCADE Case tool to concern safety and reliability. The function for the EMU is implemented in software easily programmed, using a functional block, graphic programming language. The control software has modular design and each module is tested with SCADE simulator. This time we focus a door control module, present a design method and a simulation method for that module.

The test apparatus that can be protected from the high-temperature combustion flame and coolant injection was successfully manufactured. In this study, the coolant-injection module had a controllable consistent pressure, and the entire combustion module was protected using a nonflammable composite liner. Every flange was designed in accordance with the DIN standard, and the entire body of the module was designed in accordance with the EN 13445 code. Additionally, the hydraulic pressure test was performed in accordance with the 2014/68/EU directive and EN 13445 standard. Finally, after manufacturing, performance tests (such as pressure tests) were conducted to verify the reliability and safety.

Hardware to implement the parallelized Floating-point rounding algorithm is described. For parallelized additions, we propose an addition module which has carry selection logic to generate two results accoring to the input valuse. A multiplication module for parallelized multiplications is also proposed to generate Sum and Carry bits as intermediate results. Since these modules process data in IEEE standard Floatingpoint double precision format, they are designed for 53-bit significands including hidden bits. Multiplication module is designed with a Booth multiplier and an array multiplier.

The steady three-dimensional computational thermal flow analysis using standard k-${\varepsilon}$ turbulence model was carried out to investigate the heat transfer characteristics of a cabin cooler for a commercial vehicle. The heat exchanging method of this cabin cooler is to use the cooling effect of a thermoelectric module. In view of the results so far achieved, the air system resistance of a cabin cooler is about 12.4 Pa as a static pressure, and then the operating point of a cross-flow fan considering in this study is formed in the comparatively low flowrate region. The air temperature difference obtained from the cold part of an thermoelectric module is about $26^{\circ}C$, and the cooling water temperature difference obtained from the hot part of an thermoelectric module is about $3.5^{\circ}C$.

In this paper, a method to identify components per unit task system is expressed with node, module, and interface. We define security subject per unit task system and explain node, module, and interface per component. According to the defined security standard in design phase, we also perform to design and elaborate security attributes for node and module as identified security subjects in their defined tables. And then we describe the composition standard for security attribute design with some examples, after classifying it into security subject, access subject, access control area, identification or verification area, and encryption.
