Requirements definition, which determines a project baseline, has a strong impact on the success of a project. However, since in-depth requirements are gradually revealed through the requirements definition process, the requirements definition is not a straight forward process and often falls into disorder. Thus project management standpoints are critical for the success of the requirements definition. In this paper, we present a framework and mechanisms of communication-centered project management, which controls the requirements definition process based on the situation of communication-oriented activities among stakeholders. In addition, we present a communication-centered project plan with a planning method. The project plan, which represents a time schedule of requirements definition activities, is made by a simulation-optimization algorithm using a stakeholder matrix showing the relations of requirements domains and relevant stakeholders. The effectiveness and the significance of communication-centered project management at the requirements definition phase are demonstrated by numerical examples.

Along with the development of the 4^th Industrial Revolution technology, artificial intelligence technology is also being used in the field of systems engineering. This study analyzed the development status of artificial intelligence technology in the areas of systems engineering core processes such as stakeholder needs and requirements definition, system requirement analysis, and system architecture definition, and presented future technology development directions. In the definition of stakeholder needs and requirements, technology development is underway to compensate for the shortcomings of the existing requirement extraction methods. In the field of system requirement analysis, technology for automatically checking errors in individual requirements and technology for analyzing categories of requirements are being developed. In the field of system architecture definition, a technology for automatically generating architectures for each system sector based on requirements is being developed. In this study, these contents were summarized and future development directions were presented.

Recently, there are many corporations, schools and institutes that apply TRIZ to solve technical problems. However, in reality, only a few cases of brainstorming applications exist in utilizing forty principles of TRIZ due to the difficulty at TRIZ problem definition. In order to facilitate TRIZ applications, this study proposes the utilization of requirement definition and description tool of systems engineering in TRIZ problem definition. No requirement definition exists in general problem types that TRIZ approach is used in implementing system solution. At most of problem situations, TRIZ users reversely infer that certain problem belongs to which requirement definition it is and recommends TRIZ tools to be used for the exact problem definition. This study also proposes TRIZ problem definition method by applying the results of requirement definition process. The application of TRIZ is demonstrated to the general situation with no problem definition where the proposed method enables the proper use of TRIZ.

High-quality digital broadcasting contents are susceptible to illegal copy and unauthorized redistribution, which makes broadcasters difficult to protect valuable media assets. So, broadcasters and content providers need the technology for copyright protection of professional digital content. Digital watermarking technology is one of the most actively developed solutions for the copyright protection. This paper suggests the requirements of watermarking technology in DTV(Digital TV) environment for copyright protection and shows the developed real-time watermark embedding/detecting system for HD(High Definition)/SD(Standard Definition) video and experimental results of the system against watermark attack tests. Our watermarking system meets the watermarking requirements of invisibility, robustness and security of DTV environment.

Systems Engineering application focused on requirement definition and management for SURION System Development Project is described in this paper. To perform the development process effectively based on systems engineering processes; Requirements Definition, Design Review, Configuration Management, Quality Assurance, Data Management, are applied in this project. In this processes, the Stakeholder's Requirements are transferred to Specifications verified with design reviews, prototyping inspections, and integration tests. All engineering data, especially verification plan & results are recorded, and traced to each requirements of system specification in Surion database. Therefore, it could be assured that all requirements of specification are evaluated and verified successfully in Surion Project.

The construction starts its business by receiving the order from client and owner. The client presents requirements and related information so that the desired result can come out while the designer and the builder express and implement the building according to set objectives and goals of project based on information on project environment and presented requirements. Because the construction project makes decisions on such objectives at its early stage and previous stage becomes the situation for decision making of next stage as the computation to implement decisions get performed. Accordingly, this study has mentioned necessity of requirement analysis and systematization of construction project, analyzed the work of construction's early stage and resented a plan for objective of construction project requirement definition model in which requirements engineering has been applied and using it while making decisions on designing.

This paper describes a requirement architecture modeling for the front end of KT-1 export version requirement definition processes to construct SDS(system development specification). The requirement definition process is a highly conceptual process that is difficult to carry out. This paper focuses on how to perform the KT-1 export version requirements definition process including the integration of process, methods and tools for the front-end activity of requirements definition process. This requirement model is structured in four segments, including requirement layering, requirement categorization, life cycle stakeholder and requirement definition process using Computer-Aided Systems Engineering tool(CORE).

Product factory is a real-time financial product design system for the Internet customers. Recently, as the number of the Internet customers increases, the importance of the product factory becomes more emphasized. However, there is not much research performed regarding its definition, properties, requirements, nor implementation. In this research, we make a clear definition of product factory, and analyze the requirements of the system from the perspectives of functions and services, and we propose an architecture that reflects the analyzed requirements. In additions, we implemented a prototypical system based on the proposed architecture to prove the usefulness of this research.

This paper is aimed at intensively examining the scope of legal protection for fashion designs under the Design Protection Act of Korea. For this purpose, this looked into how the Act defines the concept of design, its requirements, and the prerequisites for acquiring design rights. The study also reviewed statutory interpretations over the judgment of the identity and similarity of designs. For more practical and substantial discussions, this research utilized cases and precedents, which had relevant legal principles. This study also figured out how both the requirements for a design definition - such as merchantability, configuration, visibility, and aesthetics - and the prerequisites for acquiring design rights - like industrial applicability, novelty, and creativity - are interpreted and utilized in actual circumstances. The authors expressed their opinions regarding the criteria of judging the identity and similarity of designs, based on a study of previous cases. Previous rulings show that aesthetics of the exterior design is used as the criteria for determining whether a design is same or similar. So, two designs, which have different specific details, are deemed same or similar, if both designs show similarity in the dominant elements. This is because both designs will produce similar aesthetic qualities. However, if the dominant elements of a design are part of the public domain, and the specific details characterize the design, the latter has to be evaluated in the process. This paper examined scope of legal protection for fashion designs using relevant precedents. The study may serve as academic materials that lead to the establishment of rightful ownership in creative activities.
