The quality certification test is usually conducted by a certifying organization to determine and guarantee the quality of software after the software development phase, commonly without the actual source code, but with by going against the product's manual. In this paper, we implement a Manual-based Automatic Test data generating tool: MaT, the test technique based on manual, that automatizes producing the test data from analysis data of software package and manual. The input data of MaT are the result of the analysis of software and manual. We propose 'menu-based test analysis model' in order to generate the input data. We believe that the proposed technique and tool he]p improving quality and reliability of the software.

시간과 관련된 테스트는 임베디드 소프트웨어뿐 아니라 전체 임베디드 시스템의 신뢰도에도 큰 영향을 미치기 때문에, 시간과 관련된 임베디드 소프트웨어 테스트는 필수적이다. 임베디드 소프트웨어는 실시간 운영체제와 대상 하드웨어와 유기적으로 연관되어 있어 테스트가 일반 패키지 소프트웨어에 비해 용이하지 않다. 본 논문에서는 시간과 관련된 임베디드 소프트웨어 테스트를 위해 필요한 항목들을 분석하였으며, 사례 수행을 통한 실험 결과를 제시 한다.

The software reliability have to be improved as one major method to enhance the quality of developed software, and its defect is detected and modified through testing as a direct way to meet the purpose before releasing. Once its reliability grows up to the target and it is released to public. there nay be operational reliability problem. The operational software reliability trend nay be different depending on the condition whether it is universal or dedicated. And its reliability estimation is changed based on the condition if it follows uniform testing efforts or Weibull testing efforts. I study the operational reliability trend of dedicated software, applying two case testing efforts for the released item.

One method to improve quality before releasing of S/W after development is to enhance the reliability, whose direct methodology is to detect and revise fault through testing. Once the S/W is released because it meets the target reliability, the operational reliability problem arises. It is obvious the operational reliability different from that of testing stage depending on the condition whether it is universal(package) S/W or dedicated S/W. I propose the methodology to calculate operational software reliability of universal and dedicated S/W in this paper.

In this paper, a software radio system, supporting the physical layer of IEEE 802.15.4 standard, has been developed using USRP(Universal Software Radio Peripheral) board and GNU Radio package of an open source development kit for software radio. The software radio system supports the standards of BPSK and OQPSK modulations for 868/915 MHz band and OQPSK modulation for 2.45 GHz band. To verify the operation of the developed system, it has been tested under the standard signals according to the frequency band and packet structures for the transmitting and receiving operation. At 2.4 GHz, the Smart RF EV board and CC2430 modules are used to check the proper operation of the software radio system. The system performance test shows that the emission power spectrum, the eye-pattern, and PER(Packet Error Rate) meet the standard. It has been confirmed that the developed system supports the PHY layer of IEEE 802.15.4.

Currently, usability tests for web sites with representative users are conducted in laboratory environment that disturbs subjects' natural behavior. These test methods are inefficient for tests that require large number of subjects, because experimenters and subjects should be located in the same place at the same time during the test. In this study, a remote usability test tool, called 'RIO' has been developed to cope with these laboratory-based experiment problems - the 'synchronism' and the 'unnatural environment'. The tool is separated into three parts: 'Project Manager', 'Remote Interaction Observer', and 'Interaction Analyzer'. 'Project Manager' sets up overall experimental parameters and actual tasks to be peformed by subjects. 'Remote Interaction Observer', endued with Microsoft Internet Explorer Control, is a modified Web Browser which records user interactions, screen images and elaborate browser events while subject performs given tasks. This module is distributed to subjects as an installable software package. When they finish all the tasks, the captured interaction data is compressed and sent to 'Interaction Data Server' automatically. 'Interaction Analyzer' visualizes interaction data from the 'Interaction Data Server'. It also generates project-scope statistics which facilitate discovering peculiar cases among interaction submissions.

Tester Interface Software (TIS) provides all software functions that are necessary for a testing device to perform the test process on a memory semiconductor package from the time the device is put into the test equipment until the device is discharged from the equipment. TIS should perform the same work over all types of equipment regardless of their tester models. However, TIS has been developed and managed independently of the tester models because there are various equipment and computer models that are used in the test process. Therefore, more maintenance, time and cost are required for development, which adversely affects the quality of the software, and the problem becomes more serious when the new tester model is introduced. In this paper, we propose the Cross-platform Tester Interface Software (CTIS) framework, which can be integrated and operated on heterogeneous equipment and OSs.

웹 서비스란 인터넷을 통한 네트워크 상에, 단일 또는 다수의 비즈니스간 기존 애플리케이션 시스템을 표준화된 기술로서 결합시킴으로써, 모든 비즈니스를 가능하게 하는 것으로서, 사용자나 개발자들은 웹 서비스가 구동되어지는 하드웨어 및 소프트웨어에 상관없이 동일한 패턴으로 서비스를 제공받거나 또는 해당 애플리케이션을 개발할 수 있다. 최근 여러 분야에서 웹 서비스 형태로 서비스를 제공하고 있으며, 이에 따른 여러 응용 애플리케이션들이 개발 중에 있다. 본 논문에서는 웹 서비스 개발 패키지인 JWSDP(Java Web Services Development Pack)(1)를 이용하여 기존 웹 서비스에 대한 동작 테스트 및 기능 분석을 할 수 있는 웹 서비스 분석 시스템을 설계하고 구현하는 방법에 대해 살펴볼 것이다.

Several different approaches and mechanisms are introduced to solve the UAV path planning problem. In this paper, we designed and implemented an agent-based simulation software using the Repast platform and Java Genetic Algorithm Package to examine an evolutionary path planning method by implementing and testing within the Repast environment. The paper demonstrates the life-cycle of an agent-based simulation software engineering project while providing a documentation strategy that allows specifying autonomous, adaptive, and interactive software entities in a Multi-Agent System. The study demonstrates how evolutionary path planning can be introduced to improve cognitive agent capabilities within an agent-based simulation environment.
