With the development of ICT, the use of software has become essential for organizations to exchange information or manage operations. However, security and software management issues that have increased with the development of ICT are issues that need to be continuously addressed. In 2021, the U.S. government has standardized and established SBOM as one of the countermeasures for software security. This research was initiated as a study to lay the groundwork for the introduction of SBOM in Korea. Based on the effects of SBOM characteristics on adoption intention, we tested management support and institutional support as moderating variables. As a result, security management was found to be a significant moderating variable for management support, and transparency was found to be a significant moderating variable for government institutional support. This study verified that SBOM adoption requires both corporate and government efforts, and the variables that are important from each perspective are different. We hope that this study will contribute to the development and adoption of SBOM.

Both the highly developed computing environment and the rapid increase of the internet users enable the present web based cluster system accounting service to help many users access to numerous data at high speed. However, the information security of users and data is also as important as the convenience of the systematic environment. Especially, the significance of damage to the individuals and organizations resulted from the data outflow, hacking and malicious coding has risen up to one of the most essential problems in the internet service business. In this study, I suggest a more safe web based cluster system accounting service solution applying SEED, the Korean Telecommunications Technology Association (TTA) standard encryption algorithm.

The CALS/EC is the world-wide accepted concept and its application domain is being expanded continuously throughout the private and public sectors. One of the essential points for realization of CALS/EC is to promote the domestic system integration(SI) industry. This paper describes the present status of the domestic SI companies and the clues to solve their facing problems. In order to evaluate the status of the current SI technology, the MBNQA(Malcom Baldridge National Quality Award) is adopted. The surveyed results show that the average levels of 14 SI companies over 7 evaluation criteria turn out to be 30% through 40% point. The major projects' activities of the SI companies on the information systems over the areas of trade, science and technology, industrial manpower, health and welfare, national security, etc are explained. Also, the competitive power of the SI companies is also discussed. As a target sample, the Korea Telecom(KT) CALS model project is described in terms of its Progresses and Problems. Furthermore, the strategic plans and detailed research items are proposed to resolve on-going issues.

Defense R&D is an essential investment for the national security. Recently our nation has also begun to initiate a number of defense R&D projects. As a lot of fund and resources are allocated to these projects, we need to identify which projects to initiate and then how to manage these projects well. Though there have been a number of studies on R&D projects in commercial sector, there are only a few studies in defense R&D sector. Moreover, these existing defense R&D studies mainly deal with the former issues, which are occurring at the stage of project planing. We are more concerned with project management issues, such as how to manage projects that had already been evaluated to undertake at the planning stage. Specifically our study aims to identify project management factors leading to the success of defense R&D projects. Results of the empirical analysis indicate that management support, user-driven requirements management, and project planning capability are key elements for project performance.

With the rapid development of AI technology, ChatGPT and other AI content creation tools are becoming common, and users are becoming curious and adopting them. These tools, unlike search engines, generate results based on user prompts, which puts them at risk of inaccuracy or plagiarism. This allows unethical users to create inappropriate content and poses greater educational and corporate data security concerns. AI content detection is needed and AI-generated text needs to be identified to address misinformation and trust issues. Along with the positive use of AI tools, monitoring and regulation of their ethical use is essential. When detecting content created by AI with an AI content detection tool, it can be used efficiently by using the appropriate tool depending on the usage environment and purpose. In this paper, we collect data on AI content detection tools and compare and analyze the functions and characteristics of AI content detection tools to help meet these needs.

For such large-scale software as for operating a switching system, the use of real-time databases is essential for data exchanges among various functions and their data processing. Under the environment of developing the DBMS software for a switching system, the application program including database manipulations is first developed on a host computer and then the developed program is loaded into a switching system for its tests. To make it possible for DBMS manipulation software to be developed on a host computer rather than a switching system itself, we developed a host-based DBMS simulation system(HDBMS). In this paper we presented the roles and functions of HDBMS, its system structure, and the technical details for implementing HDBMS.

Recent Enterprise System has component driven real-time distributed architecture (RDA) and this kind of architecture should performed with satisfying strict constraints on life cycle of object and response time such as synchronization, transaction and so on. Microsoft's .NET platform supports RDA and is able to implement services including before mentioned time restriction and security service by only specifying attribute code and maximizing advantages of OMG's Model Driven Architecture (MDA). In this study, a method to automatically generate an extended model of essential elements in an enterprise-system-based RDA as well as the platform specific model (PSM) for Microsoft's .NET platform are proposed. To realize these ideas, the functionalities that should be considered in enterprise system development are specified and defined in a meta-model and an extended UML profile. In addition, after defining the UML profile for .NET specification, these are developed and applied as plug-ins of the open source MDA tool, and extended models are automatically generated using this tool. Accordingly, by using the proposed specification technology, the profile and tools can easily and quickly generate a reusable extended model even without detailed coding-level information about the functionalities considered in the .NET platform and RDA.
