Connectivity and trust in social networks have been exploited to propose applications on top of these networks, including routing, Sybil defenses, and anonymous communication systems. In these networks, and for such applications, connectivity ensures good performance of applications while trust is assumed to always hold, so as collaboration and good behavior are always guaranteed. In this paper, we study the impact of differential behavior of users on performance in typical social network-enabled routing applications. We classify users into either collaborative or rational (probabilistically collaborative) and study the impact of this classification and the associated behavior of users on the performance of such applications, including random walk-based routing, shortest path based routing, breadth-first-search based routing, and Dijkstra routing. By experimenting with real-world social network traces, we make several interesting observations. First, we show that some of the existing social graphs have high routing costs, demonstrating poor structure that prevents their use in such applications. Second, we study the factors that make probabilistically collaborative nodes important for the performance of the routing protocol within the entire network and demonstrate that the importance of these nodes stems from their topological features rather than their percentage of all the nodes within the network.

This research intends to observe the effects of social capital regarding fashion social enterprises on the community sense of participating consumers, and verify the relationship of the effects that such social capital and community sense have on sustainability formation variable(shared values, suitability of values, behavioral flow, cognitive belief and long-term relationship orientation) of social enterprises. For such analysis, a sample of 400 consumers with experience of purchasing products of fashion social enterprises more than once was utilized, and path analysis was conducted utilizing AMOS 20.0. As a result of this research, first, information sharing, social participation among the characteristic factors of social enterprises' social capital had a meaningful impact on shared values, and self-pursuit and significance meaningfully affected the suitability of values. Second, mutual influence, sense of belonging, satisfaction of needs and emotional bond among the characteristic factors of community sense between social enterprises and consumers meaningfully affected shared values, whereas mutual influence, sense of belonging and emotional bond substantially influenced suitability of values. Third, shared values and suitability of values affected the relationship between behavioral flow and cognitive trust, and behavioral flow and cognitive trust both had meaningful impact on long-term relationship orientation.

Recently, MANET has been used in many fields as the range of applications increases. However, the dynamic topology that MANET has makes it difficult to route and provides the cause of exposure to security vulnerabilities. Therefore, the security features that can be robust to many attacks must have been applied in the routing technique provided in the MANET. In this paper, we propose a secure routing method that secure route is established by reliability evaluation of nodes and secure data communication has applied through key exchange mechanism. The proposed technique used hierarchical structure for efficiency of reliability evaluation of nodes. The reliability of nodes is performed by trust management node and reliability of nodes managed periodically is broadcasted. And the key exchange for secure data transmission is dene without CA as the certificate issuing organization. This allows fast key exchange and the integrity of data transmission improved. The proposed technique improves the security of the data transmission because a secure route to the destination node is established by the reliability evaluation and the data transmission is performed after the key between the source node and the destination node is exchanged through the established route.

The core value of finance is credit. It can be said that without credit, there can be no finance. The distributed structure of the blockchain and the low-cost trust-building mechanism based on mathematical algorithms provide a new solution and path for solving and optimizing related problems in the financial field. The blockchain technology is applied in the development of the financial industry through consensus mechanisms, smart contracts, and distributed networks. In this research, a comprehensive survey of the blockchain technology is proposed in the development of financial services including equity crowdfunding and credit investigations in inclusive finance, cross-border remittance, Internet financial payment, P2P lending, supply chains finance, and the application of blockchain in the field of anti-money laundering. This paper discusses the role of blockchain in solutions to different issues in the financial field. It also discusses the architectures in different financial service application scenarios from the perspective of the financial trust mechanism and the perspective of the technology and rule change of blockchain participation in financial innovation. Finally, the problems and challenges of blockchain in financial services are discussed, and corresponding solutions are proposed.

본 연구는 대표적인 생성형 AI 기술인 ChatGPT의 이용자 신뢰를 중심으로 이용실태와 지속사용의도에 영향을 미치는 요인, 그리고 신뢰의 영향력이 목적에 따라 달라지는지를 탐색적으로 살펴보았다. 이를 위해 ChatGPT를 많이 이용하는 20대와 30대를 대상으로 설문조사를 실시하였으며 통계 패키지 프로그램인 IBM SPSS 27과 SmartPLS 4.0을 적용하여 분석을 수행하였다. Bhattacherjee의 기대충족모델(ECM)을 기반으로 구조방정식 모델을 구축하고, 경로분석과 다중그룹분석(MGA)를 실시하여 가설을 검증하였다. 본 연구의 결과는, 첫째, ChatGPT 이용자들은 일상적인 도구로 사용하기보다 특정 목적이나 필요에 따라 사용하고 있으며, 대부분의 사용자가 ChatGPT의 환각효과(Hallucination)에 대해 인지하고 있으나 이는 사용을 저해하는 요인은 아니었다. 둘째, 가설검정 결과 독립변수인기대충족, 인지된 유용성, 사용자 만족 요인 모두가 종속변수인 지속이용의도에 긍정적 영향을 미치고 있음을 확인하였다. 셋째, 이용자가 ChatGPT를 이용하는 목적에 따라 신뢰의 영향력이 달라짐이 확인되었다. 이용자가 정보 검색 목적으로 ChatGPT를 활용하는 경우에는 신뢰가 사용자 만족에 영향을 미친 반면, 창작 목적으로 사용하는 경우 영향을 미치지 않는 것으로 나타났다. 본 연구의 결과가 향후 사회와 기업에 있어 생성형 AI의 도입 과정에서 신뢰성의 문제를 해결하고 성공적인 도입을 위한 정책 수립 및 개선방안 도출을 위해 활용될 수 있기를 기대한다.

The main security threats in MANET are integrity and non-repudiation. In the meantime, a lot of secure routing protocols have been designed in order to block these security threats. In this paper, partnership-based authentication technique is proposed in order to provide participation exclusion of network and non-repudiation for the nodes. The proposed technique is a technique that participates in data communication for only the nodes receiving the authentication through the authentication process for the nodes. For this, the proposed technique is largely consists of two steps. The first step is the process that issued the certificate after the reliability for the nodes participating in the network is evaluated. And in the second step, the key exchange agreement with the neighbor nodes is performed and data communication is made after setting security path with responding nodes. The level of security in data transmission is improved because the process of path setting is performed through cooperation with a neighboring nodes having high reliability during the course of these two steps. The superiority of proposed technique in this paper was confirmed through the comparative experiment.
