최근 Internet of Things (IoT) 기반 Wireless Networked Control System (WNCS)에서 Sensor의 Status Update 및 Actuator로의 Actuation Update 분석을 위해 정보의 신선도를 측정하는 지표인 Age of Information (AoI)가 고려되고 있다. 또한 WNCS에 Edge Computing (EC)이 도입되면서 기존의 Cloud Computing 기반 아키텍처보다 낮은 AoI를 보장할 수 있다. 하지만 Controller가 관리하는 Sensor의 수가 증가하면서 Controller에 부하가 증가하여 AoI 요구사항을 만족시키지 못하는 문제점이 발생하게 되었다. 본 연구에서는 이러한 문제를 해결하기 위해 Actuator의 컴퓨팅 능력을 활용하여 Sensor의 Status Update를 해당 지역의 Actuator가 가용할 때 직접적으로 전송하여 Actuator가 직접 Actuation Update를 수행함으로써 AoI 요구사항을 만족시키고자 한다. 이를 위해 본 연구에서는 AoI 분석을 위한 분석 모델을 제시하였고 시뮬레이션을 통해 제안하는 방법이 기존 방법 대비 AoI를 줄일 수 있음을 보였다.

The number of internet electronic commerce users has increased steadily and EC is now considered not only as the communication tools, but also as the economic activity. But in spite of these global trends, current studies limited to managerial approach are insufficient in the evaluation of EC policies and situations. The purpose of this study are to present satisfaction of customers who will operate foreign internet shopping mall, and to analysis after-purchase behavior on EC satisfaction. As a result of making regression analysis, for its satisfaction. the hypotheses on "Shopping Mall Contents", "Information supply", "Convenience of order process", "Economy", "The reliability", "Customer Service" were accepted at the p<.0.05 level of significance, for its after purchase behavior, the hypotheses on "Shopping Mall structure", "Convenience of order process", "Economy", "The reliability", etc factors were accepted at the p<0.05 level of significant in 4 factors. In order words, electronic commerce satisfaction became greater when better convenience and economy were provided, the ethics were observed better, more diverse information was supplied and better system support was given, and those who had a higher educational background or better perception of electronic commerce felt more satisfaction. Finally, more usefulness of electronic commerce led to bigger satisfaction after purchase.

CALS/EC is about doing business electronically. It is based on the electronic processing and transmission of data, including text, sound and video. It encompasses many diverse activities including electronic trading of goods and services, online delivery of digital content, electronic fund transfers, electronic share trading, electronic bills of lading, commercial auctions, collaborative design and engineering, online sourcing, public procuremet, direct consumer marketing, and after-sales service. It involves both products(e.g. consumer goods, specialised medical equipment) and services(e.g. information services, financial and legal services); traditional activities(e.g. healthcare, education) and new activities (e.g. virtual malls). CALS/EC will be emerging to replace and substitute the role of the conventional market. By changing and eliminating some processes of the transactions, the electronic market and the electronic commerce will redistribute the power and hence the benefits of the market activities. Traditional way of doing business may enter into the new electronic market because the role and function of trust and established reputation will be reinforced in the electronic market. The CALS/EC through the Internet has been in the spotlight in the shopping behavior of the consumers. Accordingly Corporates are trying to adapt themselves to those rapidly changing environments being affected by the Internet. Among others, particularly to be noted is the CALS/EC between corporations and consumers whose potential growth can be considered very substantial. This report, focusing on the introduction of CALS/EC for the logistics of SMEs, will allow us to prepare more efficiently for the coming 21st Century. It is obvious that CALS/EC is fast becoming the useful way of exchanging not only information but products in business between firm-to-firm and firm-to-customer.

As a new environment, the Internet proposes to us the innovation of our life. New information technologies(IT) have enabled and stimulated new organizational forms. Electronic Commerce is the new economy that changes the pattern of our life and the form of business transaction. Electronic Commerce is rapidly growing due to the increasing of internet user and the development of information technology. With the emergence of the Internet, a totally new business, the electronic commerce(EC) is emerging. Internet EC brings in many benifits to the organization such as reduced costs, fast turnaround, better customer service, and in some firms strategic advantage over their competitors. As a newly created interior design paradigm, this proposal presents its utmost advantage, interlocking interior design firm management with virtual reality of internet. Appropriately interacting on-line with off-line in virtual reality of internet improves the image of interior design firm and makes the best use of its identity in marketing. This application can rightly attract consumers' interest. Analyzing the market, the most important thing in marketing is to anticipate consumers' existing and possible demand in future. In other word, servicing consumers with idea efficiently is competence. As the point of management, to maximize managing value in interior design proposes the application of internet to management strategy of interior design firm

Since B2C EC websites not only become a valuable channel for selling goods to customers and for communicating with the potential clients, but also offer companies an important vehicle for attaining competitive advantages in the new digital economy, the design and content of website must reflect its business goals and customers' needs. However, as little empirical evidence on the effect of B2C EC website contribution of firm performance exist, the functionality of B2C EC website has been decided voluntarily from its business experience. Hence, there has been a call for a rigorous empirical studies to examine the function level of an B2C EC website application. The purpose of this study is to examine the relationship between the function level of B2C EC website and its performance considering the characteristics of B2C EC strategy as moderating variable. 125 questionnaires from internet shopping malls which sell physical goods direct to an individual end consumer were collected. The results showed that four factors(price, product recognition, reliability enhancement, and purchase confidence) affect positive effects on the performance of shopping mall, and the characteristics of B2C EC strategy can be considered as a significant moderating variable between price factor and the performance of shopping mall.

As the Internet has been used widely in modern firms for gaining competitive advantage in the market, EC (Electronic Commerce) emerged as one of strong alternatives for this purpose. Many researchers and practitioners have proposed a wide variety of EC frameworks that can consider only the structured conditions, but there exists no EC mechanism in which engaged entities can take into account the various unstructured conditions. With the conventional EC framework, the structured EC conditions such as price, quantity, delivery date, etc. can be fully negotiated during the EC process. However, no studies have been conducted on the issue of incorporating those unstructured conditions which are difficult to represent in an explicit form and therefore hard to consider explicitly during the EC process. They are characterized by causal properties. This means that we should have a new EC mechanism which is capable of dealing with causal knowledge. In this sense, we propose a FCM (Fuzzy Cognitive Map)-based simulation framework for EC to resolve the problem of considering the unstructured conditions during the EC process. We experimented our prototype with several illustrative examples and proved that our approach is robust and meaningful.

Recently; EC(Electronic Commerce) is increasing with high speed based on the expansion of Internet. EC which is done on the cyber space through Internet has strong point like independence from time and space. On the contrary, it also has weak point like security problem because anybody can access easily to the system due to open network attribute of Internet. Therefore, we need the solutions that protect the security problem for safe and useful EC activity. One of these solutions is the implementation of strong cipher algorithm. NC(Nonpolynomial Complete) cipher algorithm proposed in this paper is good for the security and it overcome the limit of current 64bits cipher algorithm using 128bits key length for input, output and encryption key, Moreover, it is designed for the increase of calculation complexity and probability calculation by adapting more complex design for subkey generation regarded as one of important element effected to encryption. The result of simulation by the comparison with other cipher algorithm for capacity evaluation of proposed NC cipher algorithm is that the speed of encryption and decryption is 7.63 Mbps per block and the speed of subkey generation is 2,42 μ sec per block. So, prosed NC cipher algorithm is regarded as proper level for encryption. Furthermore, speed of subkey generation shows that NC cipher algorithm has the probability used to MAC(Message Authentication Code) and block implementation of Hash function.
