In this review, several new technologies considered when providing an open service environment in a mobile communication network are described. Recently, 3GPP developed some standards related to IoT services for opening a service platform in an SCS environment based on the OSA concept in a 3GPP LTE system. Similarly, the development of a new framework is underway to allow a plurality of services to commonly use an API environment in which a service provider or client accesses a 5G mobile communication system. Extending the existing LTE SCEF concept, the standardization of the northbound API is applied in the 5G CAPIF environment. Therefore, it is possible to construct a framework that facilitates access from outside, and takes advantage of the common management of various open service environments. An open service platform environment is expected to play an important role in transforming a network with simple connectivity services into a variety of new service markets, or into a service environment that can create added value.

Research on the Development of EPUB SCP(Secure Content Protection) Technical Specification and International Standardization has been carried out as a R&D project granted by the Korea Copyright Commission since 2014. The research aims to build a standard framework for the EPUB DRM(Digital Rights Management) based on the Readium LCP(Licensed Content Protection) and KS EPUB DRM specifications, to develop element technologies for the framework, and to standardize it as an IDPF(International Digital Publishing Forum) industrial standard. One of the essential features of the EPUB DRM developed though this study is to support the lending model of the digital library. This paper introduces LSD(License Status Document) specification which is a DRM license management protocol for the digital library lending process, and also represents a model which can automatically test the implemented entities of the LSD specification, test scenarios and test materials.

A new logistics concept is needed through the sharing information between suppliers and consumers, which maximizes the customers service and its flexibility by changing functional- oriented to process-oriented. As in many other industries, communication and data manipulation technology have led to systematical change to the logistics industry. One of the biggest changes of the industry that lies ahead is Consolidated Transportation. To improve this systematically false logistical environment, developing an integrated logistics information system with consolidated transportation, framework, standardization, and data integration is essential. However, no party outstands as the leading party for nationwide improvement of logistics, nor does the right analysis and design for it. Therefore, successful nationwide logistics model is yet to exist. This paper provides individual parties, which consider efficient consolidated transportation as their business models, with instructions for logistics information system so that they could be competitive in the market. It also helps companies collect user requirements for efficient consolidated transportation, and utilize it for its development. Finally, this paper extracts the design of algorithm for the efficient consolidated transportation.

The main purpose of this research is to propose standardization of construction components design with BIM and to develop WLCM Framework and Application System for supply chain management on interaction of stakeholders based on proposed standard component. To accomplish main purpose of this research, we planned three years period, in first year, we will develop model for building lifecycle based on BIM, and this model can give the chance of collaboration with stakeholders of building project. In second year, we will develop WLCM system with model, and to improve performance of application model/system. This study can contribute on reduction of whole lifecycle cost, with preventing omission of factors on cost reduction possibility, develop concurrent engineering framework for construction stakeholders with proposed BIM.

국가나 기업이 보유한 기술을 국제 표준에 반영하기 위한 표준화 활동은 국가의 산업 발전은 물론 기업의 생존이 걸린 중요한 문제라고 할 수 있다. 그리고 21세기 지식정보사회에서 우리나라가 정보화를 조기에 실현하여 지식정보강국으로 도약하고, 세계 정보통신 시장에서 주도적인 위치를 확보하기 위해서는 정보통신시장을 주도할 핵심기술에 대한 국제 표준화를 추진하는 정보통신 표준화 전략 수립 및 체계적인 추진이 필요하다. 따라서 본 논문에서는 기존의 기술로드맵 체계 및 표준화 로드맵 수립 사례를 분석하여 기술개발과 연계한 표준화 로드맵을 수립하기 위한 체계적인 접근방법과 체계(framework)를 제시하여 국내 개발기술의 국제 표준화를 촉진하고 표준화 활동의 초석을 마련하는 것을 목적으로 한다.

Nowadays, efforts are in progress for the standardization of CORBAbased telecommunication network management framework. To implement a network management system based on the framework completely, CORBA ORB and some of CORBA service should be installed in the element. And then, there must be the naming tree, which correspond to the containment relationships between components in the network element. If we use conventional OMG naming service to form the naming tree, all MOs, a software fragmenthat corresponds to each component in a system, should be instantiated. However, the network element is usually a kind of limited resource system, which cannot provide sufficient resources for applications run on it. Hence, instantiatingall MOs can cause problems for that kind of system, This paper presents Smart Naming Service architecture as a solution to the problem.

With the timeline released by ITU-R (Radiocommunication Sector of the International Telecommunication Union), research and development activities for the International Mobile Telecommunications for 2030 and beyond (IMT-2030) are now in full swing. We provide an overview of the general process of making global core specifications for next-generation mobile systems and summarize the ITU-R Recommendation of the IMT-2030 Framework. The ITU-R Recommendation focuses on IMT-2030 usage scenarios and related capabilities. The expectations of 3GPP (Third Generation Partnership Project) activities for the proposal of candidate IMT-2030 global core specifications to the ITU-R are also discussed. The launch of IMT-2030 for commercial purposes is expected to begin in 2030.

The concept of construction information systems (IS) is very comprehensive and subjective. Acronyms in relation to the construction IS may include BIM, CIC, IT, nD-CAD, ERP, CALS, KM and so on. These terminologies are used in a somewhat mixed way causing possible misunderstandings in research and practice of construction information systems. Moreover, ever-changing construction business environment has widely affected the roles and methods of utilizing construction IS. Examples of these changes are dissemination of alternative project delivery systems, global standardization under highly competitive overseas market, and advancement of information and communication technologies. In this context, the purpose of this paper is to propose a high-level framework for information systems in the construction industry. Several different concepts in the area of construction IS were investigated first in order to identify the major variables of the framework. Trends of research and real-world implementations were then analyzed to support the rationale of the variables. Finally, a framework was proposed by re-arranging the relevant issues. Findings of this paper indicate that different acronyms commonly share many similar concepts in their definitions, however, in each acronym, the motivations and approaches to implementing construction IS are very different. Different approach can provide maximum effectiveness, while overlaps may happen causing practical inefficiency.

Fueled by international efforts towards AI standardization, including those by the European Commission, the United States, and international organizations, this study introduces a AI-driven framework for analyzing advancements in drone technology. Utilizing project data retrieved from the NTIS DB via the "drone" keyword, the framework employs a diverse toolkit of supervised learning methods (Keras MLP, XGboost, LightGBM, and CatBoost) enhanced by BERTopic (natural language analysis tool). This multifaceted approach ensures both comprehensive data quality evaluation and in-depth structural analysis of documents. Furthermore, a 6T-based classification method refines non-applicable data for year-on-year AI analysis, demonstrably improving accuracy as measured by accuracy metric. Utilizing AI's power, including GPT-4, this research unveils year-on-year trends in emerging keywords and employs them to generate detailed summaries, enabling efficient processing of large text datasets and offering an AI analysis system applicable to policy domains. Notably, this study not only advances methodologies aligned with AI Act standards but also lays the groundwork for responsible AI implementation through analysis of government research and development investments.
