This study presents states-of-the art overview of the system level electrostatic discharge (ESD) analysis and testing. After brief description of ESD compliance standards and ESD coupling mechanisms, the study provides an in-depth review and comparison of the various techniques for the system level ESD coupling analysis using time and frequency domain techniques, full wave electromagnetic modeling and hybrid modeling. The methods used for improving system level ESD testing using troubleshooting and determining the root causes of soft failures, the optimization of ESD testing and the countermeasures to mitigate ESD problems are also discussed.

The purposes of this research are to modelize test system of SM TESTING by ARENA, software, input several items of specimen's testing process, resources of system and transfer loop, etc, give a hypothesis and then, obtain results reducing the efficiency of the whole system finally by overload of specific facilities in the testing system through the simulation so as to obtain several materials such as specimen and testing facility, transfer loop, etc. by simple and various forms without any necessity of numerical modelization. It will add facilities of over load and reduce facilities with low operation rate, so increase the efficiency of the system.

Effective Training has been recognized as one of the most important success factors for enterprise resource planning (ERP) system operations. However, both ERP system vendors and user companies have failed to provide an effective training method for users because practical business process cases cannot be formalized. Also, incomplete testing by ERP system vendors results in insufficient and ineffective user training. This paper suggests a scenario framework for ERP testing and training (SF-ETT). SF-ETT is constructed by expanding the practice-based ERP testing scenario construction framework designed for uniERPII. SF-ETT contains concrete business process entities that users understand actually and provides practice definition, notation, and architecture.

Measuring technology based on the computer and software is used worldwideiy by the aids of remarkably improved digital technology and measuring devices, and the electro- magnetic interference due to high currents and high voltages is being solved by the helps of applied optic instrumentation technology. The automatic acquisition, analysis and storage system of test data is available for utilizing the numerical computation technology. The measuring accuracy and testing efficiency are thus much higher because of the developed technologies. In this paper, the construction of data acquisition system in KERI including measuring devices and its application to the short circuit test are described, and additionally the algorithm of the analyzing program for the automatic process of test data and the results of analyses are described.

Real-time embedded systems have become pervasive in general industry. They also began to be applied in such domains as avionics, automotive, aerospace, healthcare, and industrial Internet. However, the system failure of such domains could result in catastrophic consequences. Runtime software testing is required in such domains that demands very high accuracy. Traditional runtime software testing based on handwork is very inefficient and time consuming. Hence, test automation methodologies in runtime is demanding. In this paper, we introduce a software testing system that translates a real-time software into a monitorable real-time software. The monitorable real-time software means the software provides the monitoring information in runtime. The monitoring target are time constraints of the input real-time software. We anticipate that our system lessens the burden of runtime software testing.

Brazing fitting which is one of the aircraft hydraulic power system components is widely used for saving weight and achieving higher reliability. Any inherent defects or damage of fitting can cause system failure and/or physical damage of human body due to highly pressurized fluid. Radiographic testing(RT) technique and additional micro-structure investigation on cut-away surfaces have been accomplished to find out some defect-like-inhomogeneity in the fittings. The radiography results showed that some defect-like-inhomogeneity existed inside body. Additional micro-structure investigation on cut-away surface reveals that the inhomogeneity is due to internal voids. In this study, it can be is said that RT technique can be a useful tool for field acceptance test of hydraulic brazing fitting in short time.

Since the late 1990's, FAA, NASA and the aerospace industry have worked together to develop the sharing system of the composite material qualification databases which were obtained through the standardized fabrication and testing procedures. The result was what is now known as the AGATE(Advanced General Aviation Transport Experiments) or NCAMP(National Center for Advanced Materials Performance) methodology, a more cost-effective concept that shifts the major responsibility for qualification and testing from the aircraft manufacturer to the material supplier. The properties of composite materials are largely dependent on the testing as well as the raw material properties and the manufacturing process including the process control parameters. Thus it is important in the composite material qualification to comply with the standardized testing procedures. In this paper, I will describe the standardized witness methodologies of certification engineers to reduce the effect of testing variability within the qualification data.

When two or more entities interact with each other as when they collaborate or communicate, the degree of correctness of the interactions is called interoperability. In software, the necessity of interoperability testing arises when we build a software system in which multiple interacting software entities are employed to perform the function or task of the system. These days as software is more and more being used to solve complex problems and through networking functions of software can be distributed to provide abundant services, the more the interoperability testing becomes important. This paper provides the framework and methodology for interoperability testing by discussing the fundamental concepts and principles that underlie interoperability and interoperability testing and the approaches for practicing interoperability testing.

This study aims to evaluate KOLIS-NET system by usefulness testing of 'KOLIS-NET client integrated system' and by usability testing of 'KOLIS-NET web site'. For evaluating the usefulness of the system, we used searching, ease of use, customer support as criteria, and used brainstorming and in-depth interview as evaluation method. On the other hand, for usability testing of the web site, we used cognitive walkthrough. Evaluation results are categorized and represented as page redesign, term consistency, function improvement and new functionality.
