The purpose of this study is how to progressed to internet shopping mall system in Korea and a improvement and characteristics of that through progress and case studies of internet shopping mall. As to the future direction of the market of internet shopping mall in Korea, many of commodity parts will be traded among established participants on internet websites owned by internet shopping mall groups. Finally, for improvement of internet shopping mall industry in Korea I suggested that there are "mutual cooperation of internet shopping mall companies", "maintain the customer's confidence", "attain the profits through a niche market strategy".

As the Internet use increases explosively, and the information provision and services via the Internet is getting active, understanding the status of the Internet use and the Internet users' characteristics becomes necessity for organizations, corporations, and in-formation providers. This paper reviews various surveys on the Internal users and the Internal one con-ducted in Korea, the United States and the United Kingdom. By the comparisons and analyses of these survey results, this paper intended to provide visions on the future direction In the Internet service provision and the Internet uses in general.

New research on internet addiction identifies online users who became hooked on internet online games, chatting, and even internet shopping only to see their lives become increasingly unmanageable because of the Internet. The purpose of this study is to examine the causal relationship between internet addiction and social psychological factors of college students. This study model used four themes(self-esteem, self-efficacy, family relationships, stress) in order to identify the effect of social psychological factors on internet addiction. The result of this study identified that self-esteem, self-efficacy, stress have a significant effect on internet addiction. Future areas for studying internet addiction are continuously discussed.

In this paper, we discuss a new architecture of future Internet for mobile-oriented environments, named Mobile-Oriented Future Internet (MOFI). The MOFI architecture is designed with Host Identifier and Local Locator (HILL) for identifier and locator separation. Based on the HILL separation architecture, we propose a Dynamic and Distributed Mapping System (DDMS) for identifier-locator mapping control. In DDMS, the mapping control function is distributed onto each access router in the domain, which is different from the centralized approach using a central anchor. For validation of the proposed MOFI-DDMS architecture, we implemented the data delivery and mapping control functions using Linux platform. From the testbed experimental results, we see that the DDMS architecture can give better performance than the existing Proxy Mobile IP (PMIP) protocol in terms of data transmission throughput.

According to the Korea Robotics Industry Association, the number of robots companies, sales and production are steadily increasing until 2016, and the global robot market outlook is expected to continue to increase until 2025. We need to develop more attention to robots that can make life easier for us and can replace human tasks that we cannot do. It is predicted that robots will be more developed in the future with the above statistics, and future robots will be more activated by robots that can depend on each other, fix each other, and adapt to the changing environment without humans. Therefore, the shape of the robots in the future will be developed as a group robot(swarmbot) that cooperate with each other while the robot works. These robots have been studied for a longtime, but there are only two community robots that are applied in real life, only two of which are jailbreaking robots made in KAIST and KIVA robots made in Amazon company. In the future, as these robots develop more and more, and environment where robots can live without human intervention is created, so that a plurality of robots can collaborate and do individual work.

In the last few years, quantum communication technology and services have been developing in various advanced applications to secure the sharing of information from one device to another. It is a classical commercial medium, where several Internet of Things (IoT) devices are connected to information communication technology (ICT) and can communicate the information through quantum systems. Digital communications for future networks face various challenges, including data traffic, low latency, deployment of high-broadband, security, and privacy. Quantum communication, quantum sensors, quantum computing are the solutions to address these issues, as mentioned above. The secure transaction of data is the foremost essential needs for smart advanced applications in the future. In this paper, we proposed a quantum communication model system for future ICT and methodological flow. We show how to use blockchain in quantum computing and quantum cryptography to provide security and privacy in recent information sharing. We also discuss the latest global research trends for quantum communication technology in several countries, including the United States, Canada, the United Kingdom, Korea, and others. Finally, we discuss some open research challenges for quantum communication technology in various areas, including quantum internet and quantum computing.

Voice over Internet Protocol (VoIP) has grown in popularity as a low-cost, flexible alternative to the classic public switched telephone network (PSTN) that offers advanced digital features. However, additional security vulnerabilities are introduced by the VoIP system's flexibility and the convergence of voice and data networks. These additional challenges add to the normal security challenges that a VoIP system's underlying IP data network infrastructure confront. As a result, the VoIP network adds to the complexity of the security assurance task faced by businesses that use this technology. It's time to start documenting the many security risks that a VoIP infrastructure can face, as well as analyzing the difficulties and solutions that could help guide future efforts in research & development. We discuss and investigate the challenges and requirements of VoIP security in this research. Following a thorough examination of security challenges, we concentrate on VoIP system threats, which are critical for present and future VoIP deployments. Then, towards the end of this paper, some future study directions are suggested. This article intends to guide future scholars and provide them with useful guidance.

Accountable Internet Protocol (AIP) is one of the future Internet architectures to provide accountability concept by using the self-certifying address that is derived by the public key of the host. In AIP, when a host sends a packet, a domain that is located between the source and the destination hosts discards the packet in order to verify the source IP address. Therefore, performance degradation can occur due to packet discard especially when there is asymmetric route. In this paper, we propose the improved AIP mechanism to verify the source IP address without discarding the packet by including the timestamp, public key value and the signature for protecting from forfeiting the source address. Security safety of the proposed mechanism is evaluated and the proposed mechanism can provide the more robust security as well as reducing the latency due to discarding packets.
