In the process of modern traffic management, information technology has become an important part of intelligent traffic governance. Real-time monitoring can accurately and effectively track and record vehicles, which is of great significance to modern urban traffic management. Existing tracking algorithms are affected by the environment, viewpoint, etc., and often have problems such as false detection, imprecise anchor boxes, and ID switch. Based on the YOLOv5 algorithm, we improve the loss function, propose a new feature extraction module to obtain the receptive field at different scales, and do adaptive fusion with the SGE attention mechanism, so that it can effectively suppress the noise information during feature extraction. The trained model improves the mAP value by 5.7% on the public dataset UA-DETRAC without increasing the amount of calculations. Meanwhile, for vehicle feature recognition, we adaptively adjust the network structure of the DeepSort tracking algorithm. Finally, we tested the tracking algorithm on the public dataset and in a realistic scenario. The results show that the improved algorithm has an increase in the values of MOTA and MT etc., which generally improves the reliability of vehicle tracking.

With the acceleration of regional economic integration, the agricultural trade network within the RCEP region presents new opportunities and challenges for member countries. This study focuses on agricultural trade among RCEP members from 2011 to 2020, utilizing social network analysis to explore the structural characteristics and evolutionary trends of the trade network. Additionally, an extended gravity model is employed to empirically analyze the key factors influencing South Korea's agricultural trade with other member countries. The findings reveal that: (1) Agricultural trade relationships within the RCEP region are stable and mature, with high interconnectivity in the trade network, indicating a trend towards balanced development. (2) The positions of member countries within the agricultural trade network are characterized by both high density and heterogeneity. (3) South Korea's agricultural trade with RCEP member countries is positively influenced by the economic size, population size, and governance level of its trading partners, while South Korea's own indicators show no significant effect. The trade distance between South Korea and member countries also has a positive impact on agricultural trade. By combining social network analysis with an extended gravity model, this study provides a multi-faceted quantitative analysis of the RCEP agricultural trade network, offering new insights into regional agricultural trade. It also provides empirical evidence for agricultural trade cooperation between South Korea and other RCEP countries.

In this paper, we propose the AI certification standardization activities for systematic research and planning for the standardization of trustworthy artificial intelligence (AI). The activities will be in two-fold. In the stage 1, we investigate the scope and possibility of standardization through AI reliability technology research targeting international standards organizations. And we establish the AI reliability technology standard and AI reliability verification for the feasibility of the AI reliability technology/certification standards. In the stage 2, based on the standard technical specifications established in the previous stage, we establish AI reliability certification program for verification of products, systems and services. Along with the establishment of the AI reliability certification system, a global InterOp (Interoperability test) event, an AI reliability certification international standard meetings and seminars are to be held for the spread of AI reliability certification. Finally, TAIPP (Trustworthy AI Partnership Project) will be established through the participation of relevant standards organizations and industries to overall maintain and develop standards and certification programs to ensure the governance of AI reliability certification standards.

In a distributed environment, data fabric refers to the technology and architecture that provides data management, integration, and access in a consistent and unified manner. To build a data fabric, it is necessary to maintain data consistency, establish a data governance system, reduce structural differences between data sources, and provide a unified view. In this paper, we propose the Fabricator system, a technology that provides data management and access in a consistent and unified manner by building a metadata registry. Fabricator manages the addition and modification of metadata schemas and matching processes by designing a matching tool called MetaSB Manager that applies B+Tree. This allows real-time integration of various data sources in a distributed environment, maximizing the flexibility and usability of data.

21세기 정보사회의 지구적 거버넌스를 구축하고자 했던 '정보사회 세계정상회의(WSIS)'가 2003년 제노바에서, 2005년 튀니스에서 개최됐다. WSIS는 세계 각 나라의 정부를 비롯해, 민간영역, 시민사회, 국제기구들이 한 자리에 모여 '지구적 정보사회(global information society)'를 위한 국제질서를 수립하고자 하는 시도였다는 점에서 의미를 갖는다. 이에 본 연구는 WSIS가 제시하는 정보사회와 정보질서의 패러다임을 살펴보고 있다. 이를 위해, WSIS의 역사적, 국제질서적 맥락을 살펴보고 있으며, 나아가 WSIS가 제시한 의제들을 검토하고 있다. 그 결과, WSIS가 새로운 지구적 거버넌스 구축을 국제사회의 모든 이해당사자들의 조율 속에서 진행했다는 점, 그리고 이러한 과정에서 개발도상국들의 이해를 점진적으로 반영했다는 점에서 긍정적으로 평가된다. 또한, 정보질서를 위한 국제사회의 중재자로 국제전기통신연맹(ITU)의 역할이 부각되었다는 점 역시 주목할 부분이다. 하지만, 정보통신기술(ICT)을 주요 수단으로 삼아 인간중심의 포괄적인 정보사회의 비전을 제시하고자 했던 WSIS의 논의는 자칫 장미빛 미래와 과도한 기술결정론에 치우칠 우려를 보여준다. 나아가, 본 논문은 WSIS 논의가 신자유주의적 질서에 입각해 있는 현재의 정치경제학적 맥락의 결여로 인해 논의의 결과인 핵심원칙들과 행동계획을 흐리게 할 수 있음을 지적한다.

본 연구는 인터넷 다국어도메인의 국제표준화에 대한 국제커뮤니케이션을 분석하여 그 대중화 실패 요인을 이해하고자 한다. 조직화 이론을 활용하여 ICANN에서 다국어도메인에 대한 필요성이 제기되는 초기 담론을 관찰하고, 기술적으로 계층적 방식이 선택되는 과정에서 어떤 갈등이 있었는지 살펴보며, 선택된 결정이 주요 이해당사자들에게 어떻게 받아들여졌는지 살펴본다. 분석 결과, 대중화 실패 요인은 미국을 중심으로 하는 ICANN과 그 필요성을 제기하였던 비영어권 국가 간의 인식론적 차이에서 찾을 수 있다. '정보격차 해소'와 '문화적 가치 추구'라는 담론은 '인터넷 인프라의 안정성'이라는 ICANN의 기술적 담론과 충돌한다. 이로써 국제표준화는 10년이라는 오랜 시간이 걸렸고 시장에서는 다양한 서비스들이 난립하는 결과를 초래하였다. 한국의 적용 사례를 보면, 도메인 무단 점유, 홍보 비용, 기술적 불안정성 및 이용자의 혼란 등 사회적 역효과가 대중들에게 외면받게 되는 요인으로 작용하였고 정부는 일관성 있는 정책을 제시하는데 실패했다.

New trend called ubiquitous leads the recent business by standardization and integration. It should be the main issue how to guarantee the integration and accountability on each business, especially in mission critical system which is mainly supported by M2M (Machine to Machine) control mechanism. This study is from the analysis of digital forensics case study that is from the M2M Sensing Control Mechanism problem of the "Imjin River" case in 2009, where a group of family is swept away to death by water due to M2M control error. The ubiquitous surroundings bring the changes in the field of criminal investigation to real time controls such as M2M systems. The needs of digital forensics on M2M control are increasing on every crime scene but we suffer from the lack of control metrics to get this done efficiently. The court asks for more accurately analyzed results accounting high quality product development design. Investigators in the crime scene need real-time analysis against the crime caused by poor quality of mission critical systems. It seems to be every need of Real-Time-Enterprise, so called ubiquitous society on the case. We try to find the efficiency and productivity in discovering non-functional design defects in M2M convergence products focusing on three metrics in study model with quick implementation. Digital forensics system in present status depends on know-how of each investigator and is hard to expect professional analysis on every field. This study set up a hypothesis "Co-working of professional investigators on each field will qualify Performance and Integrity" especially in mission critical system such as M2M and suggests "Online co-work analysis model" to efficiently detect and prevent mission critical errors in advance. At the conclusion, this study proved the statistical research that was surveyed by digital forensics specialists around M2M crime scene cases with quick implementation of dash board.
