In order to develope a common ground system, a general procedure language that can be used in both EGSE and MCS is primarily needed. As the first step in developing a common test and integration procedure language, KARI's ATS for AIT and MCE for GS were compared to some of the most representative languages such as PLUTO regarded European standard, STOL and ELISA and PIL. Based on the analysis, design features of developing a common test and integration procedure language were presented.

In this study, safety management procedures were developed based on domestic and foreign guidelines and related maritime law to ensure the safe development and implementation of smart autonomous ship technology and Samsung Heavy Industry. The safety management procedure was developed according to the guidelines for (MASS) sea trials (MSC.1/Circ.1604, Annex: Interim guidelines for MASS trials), proposed by International Maritime Organization (IMO) for the relevant authorities and stakeholders of MASS to properly conduct tests of systems and infrastructure related to safety and environmental protection. The developed safety management procedure applies to the maritime demonstration test of a system applying autonomous navigation element technology mounted as a navigation aid on a ship operating under a watch system, while complying with the environmental protection and navigation safety of the coast of Korea.

IPTV는 방통융합의 대표적인 매체로 자리 매김하며 2008년 상용서비스를 시작으로 계속 진화하고 있다. 그러나, 초기 서로 다른 방식으로 IPTV 서비스를 시작함으로 인해 상호운용성 문제가 대두 됨에 따라, TTA를 통해 IPTV 분야의 표준화가 시작되어 현재도 다양한 IPTV 분야의 기 제정된 표준의 개정 작업 및 신규 분야의 표준화를 계속 추진하고 있다. 이렇듯 표준화가 진행됨에 따라, IPTV 단말의 사업자 간의 이동성을 보장하기 위한 노력이 계속되고 있으며, 그 중 하나로 IPTV 단말 프로비저닝 절차 표준화가 추진되어 현재까지 2번의 개정 작업을 통해 표준안의 보완/수정 작업 등이 진행되어 2차 개정판이 완료되었다. 이에 TTA에서는 해당 표준을 구현한 STB 등 단말과 서버에 대한 표준적합성 시험을 위한 시험규격을 개발하였다. IPTV 단말 프로비저닝 절차 표준에서는 단말의 네트워크 접속부터 펌웨어/소프트웨어 업그레이드, IPTV 서비스를 탐색하기 위한 정보 전달을 위한 절차를 정의하고 있으며, 각 절차별 데이터 형식 및 프로토콜을 검증하기 위한 시험항목을 개발하였으며, 표준안 검증 및 시험 서비스 제공을 위한 시험환경을 구축하였다.

The function and performance test of the developed sub-system should be conducted before integrating into the total system. For the successful achievement of the flight test, the integration tests of sub-systems must be performed to eliminate and prevent abnormal conditions, which may happen due to ground problems, Electro-Magnetic Interference noises, and so on. This paper describes the certification test procedure and results for the roll axis attitude control system of Korea Sounding Rocket-III.

This study described about the procedure and method to type certification of KAS 23 civil aircraft that is developed in domestic. It is important to obtain type certification within defined period based on the proposed process and method to prove compliance through certification basis according to certification plan. This process referred to FAA Order 8110.4 C, "Type Certification" and domestic regulation and showed example of compliance check list(CCL) defining means of compliance(MOC). Also, proposed method to prove compliance according to means of compliance and classified item of test & evaluation.

The Korea Institute for Advancement of Technology and the Ulsan ICT Promotion Agency are building an electric smart ship using a full range of ICT with advanced technology, and are expected to demonstrate it in 2022. For the demonstration of onboard ship equipment, it needs to develop a demonstration procedure. There are 4 types of onboard equipment preferentially selected for the development of the demonstration test procedure which are an electronic chart display and information system, a ship RADAR system, a voyage data recorder, and a ship energy efficiency monitoring system. This paper describes the demonstration procedure based on the equipment standard for the electronic chart display and information system among 4 selected types of demonstration equipment, and also the verification test checklist and template is introduced.

In this study, the aircraft technical standards of the Korea and the United States were analyzed to derive the dynamometer test procedure required to prove the compatibility for flight test certification of the metal brake pad for transport aircraft. Since the design modification of the brake systems is classified as a major change, the STC(Supplemental Type Certificate) and the PMA(Parts Manufacturer Approval) are required. In accordance with the TSO-C135a, the technical standard order for brake system in the United States, the design landing-stop test, accelerate-stop test, and most severe landing stop test were selected among the test items for flight test. The conditions for the dynamometer test are determined according to the specifications provided by aircraft manufacturer, and the brake pad condition, deceleration, and the number of test are defined according to the TSO-C135a.

A software engineering process has been developed for the design of safety critical software for Wolsong 2/3/4 project to satisfy the requirement of the regulatory body. Among the process, this paper described the detail process of validation testing peformed to ensure that the software with its hardware, developed by the design group, satisfies the requirements of the functional specification prepared by the independent functional group. To perform the test, test facility and test software ore developed and actual safety system computer was connected. Three kinds of test cases, i.e., functional test performance test and self-check test were programmed and run to verify each functional specifications. Test failures ore fedback to the design group to revise the software and test result were analyzed and documented in the report to submit to the regulatory body. The test methodology and procedure were very efficient and satisfactory to perform the systematic and automatic test. The test results were also acceptable and successful to verify the software acts as specified in the program functional specification. This methodology can be applied to the validation of other safety-critical software.
