The purpose of this study is to approach information security from a more comprehensive perspective. Particularly, information countermeasures includes a technological tool for end users, thereby increasing the end users' technological stresses. Based on the technostress framework, we investigate a effect of security awareness training on technostress, and also examine a effect of technostress on the persistent security compliance. Results showed that security awareness training influenced on techno-overload and techno-uncertainty. We also found that techno-overload and techno-uncertainty have a significant effect on the persistent security compliance. Conclusion and implications are discussed.

The proposed mechanism has an group management server, which manages the information about both the receivers and the senders. Any receiver can dynamically join/leave the multicast VC. The signaling overload due to group membership changes is not concentrated on the sender, but it is distributed to many receivers for the scalability improvement. The associated signaling messages propagates from the receivers to the ATM switch dedicated to the multicast VC, and hence no signaling overload exists in the shared links there is no latency for the receiver to wait. Our proposed scheme is superior in the view of scalability, the efficiency and the latency to other schemes.

Recently, there has been interests in smart vessel technology, and it needs to consider an intelligent control system for efficient vessel manangement. In a smart vessel, however, it can cause a network overload due to a number of data transmission from a variety of sensor nodes and bridge nodes. In this letter, we propose an data transmission scheme with data fusion to reduce the number of traffic from the sensor nodes. Hence it can decrease network overload for intelligent vessel management.

With the development of the e-commerce market, various types of products continue to be released. However, customers face an information overload problem in purchasing decision-making. Therefore, personalized recommendations have become an essential service in providing personalized products to customers. Recently, many studies on GCN-based recommender systems have been actively conducted. Such a methodology can address the limitation in disabling to effectively reflect the interaction between customer and product in the embedding process. However, previous studies mainly use implicit feedback data to conduct experiments. Although implicit feedback data improves the data scarcity problem, it cannot represent customers' preferences for specific products. Therefore, this study proposed a novel model combining explicit and implicit feedback to address such a limitation. This study treats the average ratings of customers and products as the features of customers and products and converts them into a high-dimensional feature vector. Then, this study combines ID embedding vectors and feature vectors in the embedding layer to learn the customer-product interaction effectively. To evaluate recommendation performance, this study used the MovieLens dataset to conduct various experiments. Experimental results showed the proposed model outperforms the state-of-the-art. Therefore, the proposed model in this study can provide an enhanced recommendation service for customers to address the information overload problem.

An increase of the interaction speed can lead to the problem of over-relations. Due to psychological and temporal burdens caused by the excessive relationship, users feel fatigue and users are avoiding using SNS. SNS fatigue and SNS anxiety is regarded as SNS stress related to the side effects caused by the SNS use. This study is to approach negative view which is SNS stress and find out causes of stress from the over-relation of interaction. This study used total of 261 samples from Facebook users. As a results, all hypothesis are accepted using SEM(Structural Equation Model). Information sharing and communication have positive effect on social interaction overload and it causes technostress. The results of this study show that SNS characteristics occurs technostress. This study is significant in that it examines that the features of SNS have negative results.

Based on the technostress theory, this study aims to explore the effect of technostress caused by the use of social media during or after work hours on job turnover intention. This study conducted an online survey targeting 341 Chinese WeChat users. According to the results of the structural model analysis, role overload, role conflict, and work invasion that occur during work affect technostress, and social interaction overload, invasion of private life, and Fear of Missing Out (FoMO) that occur after work have a effect on technostress as well. Technostress occurring during work did not appear to have an effect on turnover intention, but technostress occurring after work was found to have a positive effect on turnover intention. It is expected that this study will be used as a basic data for the correct use of social media within an organization.

In this paper, the function of starting the negative voltage used in the IT equipment when it is generated and the method of controlling it using a microcontroller for the function to detect the overload and respond to it are presented. To do this, the limitations of the existing negative voltage generation circuit and the problems that occur during overload were analyzed, and a circuit that detects and controls the overload condition without a separate current sensing circuit was presented. In order to confirm the effect of the proposed method, an experiment was conducted by configuring an experimental circuit. As a result of the experiment, compared to the existing negative voltage generation circuit, which falls into a latch-up state when overloaded and enters a dangerous state, the proposed circuit detects this, stop the operation of the circuit, and informs the user of such an abnormal state to take action. have. In addition, since the starting point of the circuit is determined according to the system state, the experimental result was confirmed that the starting time was significantly shortened by about 23% compared to the time switch method.

Organizations amplify their information security (IS) technical investments as the demand for IS escalates. This research suggests conditions for enhancing insider compliance with IS, focusing on the potential for behavior modification through techno-stress and organizational justice, based on the theory of planned behavior. To test the proposed hypothesis, this study utilized a survey methodology on 383 employees from companies with implemented IS. The test results showed that IS techno-stress (overload and uncertainty) caused by reduced attitudes of employees, and organizational justice increased subjective norms, influencing IS compliance intentions along with self-efficacy. Additionally, organizational justice has been found to alleviate the adverse effects of IS overload and uncertainty on attitudes. The findings are expected to help clarify measures for achieving IS performance within the organization by proposing organizational justice conditions to improve the negative IS environment of the organization.

현재의 정보 과적재(information overload) 상황은 대량의 정보 가운데서 사용자의 관련 정보에 대한 요청을 도와 불필요한 정보로부터 막기 위한 도구가 매우 필요한 실정이다. 이러한 도구중 대표적으로 사용되는 웹 검색 엔진과 같은 정보 검색 시스템의 단점은 적합한 검색용어를 선택해야만 하는 점과, 결과에 대한 효율적인 요약이 제공되지 않는다는 점이다.따라서 본 논문에서는 이러한 검색 엔진에서의 단점을 보완하여 사용자를 정보 과잉 상황에서의 불필요한 정보로부터 보호하기 위해, 사용자의 프로파일을 기반으로 하여 정보를 개인화된 요약과 함께 제공하는 정보 여과 에이전트(information filtering agent)인 '사용자 맞춤의 문서 요약을 제공하는 정보 여과 에이전트 시스템'을 제안한다.

The purpose of this paper was to present the method of progress efficiency of morphosyntaxical analyzer for French information processing in the view of multilingual information processing. This study indicated that he method prohibit the additional useless word type by decomposing word type by decomposing works which were created by morphological amalgamation. Findings also suggested the need of preprocessing in order to decrease the overload of morphosyntaxical analysis algorithm. In addition, general rules were proposed to divide word form and to decompose complex sentence.
