Korea is the only country in the world where the regulation of vehicle homologation has been changed from "Type Approval" to "Self-Certification". But there are some regulations that have not been fully changed, so they became double-regulations. In this research, we find out double-regulations in Self-Certification systems focused on "Specification Notice Procedure", and suggest a proposal of amendment to avoid duplication. Through the research, we can reduce unnecessary requirements about homologation, management of vehicle and administrative procedure significantly.

This paper presents a documentation and development method to facilitate the certification of scientific computing software used in the safety analysis of nuclear facilities. To study the problems faced during quality assurance and certification activities, a case study was performed on legacy software used for thermal analysis of a fuelpin in a nuclear reactor. Although no errors were uncovered in the code, 27 issues of incompleteness and inconsistency were found with the documentation. This work proposes that software documentation follow a rational process, which includes a software requirements specification following a template that is reusable, maintainable, and understandable. To develop the design and implementation, this paper suggests literate programming as an alternative to traditional structured programming. Literate programming allows for documenting of numerical algorithms and code together in what is termed the literate programmer's manual. This manual is developed with explicit traceability to the software requirements specification. The traceability between the theory, numerical algorithms, and implementation facilitates achieving completeness and consistency, as well as simplifies the process of verification and the associated certification.

In the perspective of service, it is important to institute certification process required by International Standard Organization (ISO) for software (SW) development process, since Information and Communication Technology (ICT) takes high portion of the Korean industry and its certification for SW is essential internationally for trade. In addition, the certification service provided by BPMN tools like ADONIS is absolutely necessary. In that perspective, this paper proposes a new approach to satisfy this kind of necessity. This approach provides the certification service for the safety of SW required at the international level in Korean industry. Furthermore, the approach can be applied to other domains beside the SW. In order to demonstrate the approach, this paper shows how to guarantee service design for certification of ECSS-E-40 of European Space Agency (ESA) with ADONIS. This paper focuses on specification and verification of SW in E-40, and the main requirement for the verification will be safety of the SW.

We have evaluated the performance and some physical properties of 25 automotive engine oils (21 domestic and 5 imported products) which are purchased on the market to verify the API(American Petroleum Institute) or ILSAC(International Lubricant Standardization and Approval Committee) certification marks attached on the products and to determine the necessity of the quality control of the engine oils on the market. 12 test items are chosen according to API engine oil specification, which are flash point, pour point, cold cranking simulator apparent viscosity, pumping viscosity, gelation index, HTHS(High Temperature High Shear viscosity), foam, high temperature foam, filterability, volatility, high temperature deposit(TEOST), phosphorus content. We have found one product which did not meet the API specification on gelation index, one on HTHS, four on foam, and one on volatility, which implies that the quality control system is in need to check the fidelity of the certification marks attached on the engine oils being marketed. In addition, this works raises the necessity of the upgrade of the present Korean engine oil specification.

Industrial structure is more developed, the economical value of human resources and the cases which risks worker's Health & Safety is expended. The Safety & Health issues are focused on elements of control for management activity simultaneously with work environment as well as the risk elements which risks worker's life and body. The activity for combination of basic management System and Safety & Health management is progressing with active discussion in ILO, BS 8800 is specified the guidance of Occupational Safety & Health Management System in UK. 1996. This research refers to BS 8800:1996, specification as a basic model, and introduce of the result of certification development result in Occupational Safety & Health management System with in ISO 14001 Environmental System Standards & ISO 9001 Quality Management System Standards and Systemic Factors. Through this applicability and efficiency evaluation, we make an effort to support and to improve the specification. Also applicability evaluation of Occupational Safety & Health management System and the specification developed for the purpose of the third party certification is applied with expending in industry, and the method is presented through the case which is required to support for method review and activities.

An aircraft, its engine and propeller are certified in processes of design, production, and operation respectively. Type Certificate is issued if the aviation authority finds that the design of aircraft, engine, or propeller complies with applicable airworthiness standards and environmental standards. The ICAO (International Civil Aviation Organization) prescribes the international standards and recommended practices of type certification for the contracting states. The FAA (Federal Aviation Administration) and the EASA (European Aviation Safety Agency) established their regulations and procedures applicable to type certification. In this paper, we compared the differences among the ICAO, the FAA, and the EASA regulations, and on this comparison, we proposed the rulemaking items to improve type certification regulations in Korea.

Purpose: To propose improved method for normalization, compare to the de facto international standard which is IESNA TM-21 or conventional normalization methods. Methods: Firstly, we analysed conventional methods and specified the problem of normalization method which is based on first measured data. Secondly, we proposed our approach which is based on the design specification. Lastly, we studied a real degradation data which is conducted for 15,000 hours. Conclusion: Proposed normalization method is better approach because it can reflect real data and design specification, and reduce distortion when analysing degradation data. Also, It is appliable to other long-life reliability items.

In order to export aircraft components or substructures, it is necessary to get a certification from the main company for the components or an airworthiness certification from the FAA. In Korea, those processes are performed by a small number of private companies for aircraft components. However, airworthiness certification has never been done in the company. To export an assembled aircraft, whether small or large, it is obligatory to get a certification for the aircraft being exported. Currently, the Korean government is trying to get BASA agreement in a few years. For a mid-size company, it is easier to get the NADCAP audit process for the supply of aircraft components to the main company. In this paper, the overall process of aircraft certification is discussed and airworthiness certification is treated for export aircraft. Moreover, the NADCAP audit process is described in detail by introducing example parts made of composite material. This detailed process would be very helpful to a small or mid-size company that wants to develop and deliver aircraft components to foreign companies.
