The invention and development of digital computer networks since the post-modern culture and creating new ideas, and in nearly all areas since the industrial revolution has had the greatest impact. A new paradigm for the 21st century, the Internet and ubiquitous, and mobile devices are being created by the new culture is being created. Rapidly being replaced by digital and analog, and 'Digilog' fusion concept has appeared. In addition, the development of computer cyberspace culture, art, design and structure are changing. In the field of furniture design, changing design processes and innovative design philosophy that change is now occurring. These symptoms experienced at the same time, almost every country on Earth is a phenomenon. Since the 20th century, computer network design based on the relationship between digital and cyber culture espoused by philosophers studied society and organic modernism and organic design of digital-based differences are confirmed through the case. Using digital technology, modeling case study of a furniture designer in cyber space and the creation of human capabilities and the fusion of computing power will be studied in modern furniture design.

Malicious social robots, which are disseminators of malicious information on social networks, seriously affect information security and network environments. The detection of malicious social robots is a hot topic and a significant concern for researchers. A method based on classification has been widely used for social robot detection. However, this method of classification is limited by an unbalanced data set in which legitimate, negative samples outnumber malicious robots (positive samples), which leads to unsatisfactory detection results. This paper proposes the use of generative adversarial networks (GANs) to extend the unbalanced data sets before training classifiers to improve the detection of social robots. Five popular oversampling algorithms were compared in the experiments, and the effects of imbalance degree and the expansion ratio of the original data on oversampling were studied. The experimental results showed that the proposed method achieved better detection performance compared with other algorithms in terms of the F1 measure. The GAN method also performed well when the imbalance degree was smaller than 15%.

Objectives : The objective of this study is to examine the experiences of Internet game experience targeting to University students in Korea. Research topics was "What is meaning of internet game to the University students?" Methods : Classical phenomenology underpinned this study. Seven qualitative studies of University students were conducted between 20 and 23 years old. Semi-structured interviews were conducted. Interviews were audio recorded and transcribed verbatim. Phenomenological thematic analysis of data was undertaken. Results : The findings pivot around three interconnected themes :[Expectations for the emotional needs], [Spend time in the cyberspace], [Relieve stress throughout the game], [Instead of satisfaction from virtual reality], [Internet gaming repeat and desires]. The basic need for getting into internet game was [satisfaction from virtual reality was identified]. While internet games was eliminated stress, [Expectations for the emotional needs] and [Spend time in the cyberspace] were the catalyst that makes them repeatedly getting into Internet the game. Based on the result, I suggest that Internet gaming should be recognized as a tool to relieve stress for college students, But it is not satisfied with the reality in virtual space. Therefore, the strategy must be to recognize reality accompanying. And Using a lot of time in cyberspace make them cause of internet game addiction. Therefore, it requires a systematic strategy for the Internet using time limits. Also the emotional needs met were motivated to repeat an Internet game. So another way to meet the emotional needs to college students should be sought.

Based on the teleportation by quantum walk, a quantum secret sharing scheme with credible authentication is proposed. Using the Hash function and quantum local operation, combined with the two-step quantum walks circuit on the line, the identity authentication and the teleportation of the secret information in distribution phase are realized. Participants collaborate honestly to recover secret information based on particle measurement results, preventing untrusted agents and external attacks from obtaining useful information. Due to the application of quantum walk, the sender does not need to prepare the necessary entangled state in advance, simply encodes the information to be sent in the coin state, and applies the conditional shift operator between the coin space and the position space to produce the entangled state necessary for quantum teleportation. Security analysis shows that the protocol can effectively resist intercept/resend attacks, entanglement attacks, participant attacks, and impersonation attacks. In addition, the quantum walk circuit used has been implemented in many different physical systems and experiments, so this quantum secret sharing scheme may be achievable in the future.

사이버공간이 독특한 사회적 공간으로 자리잡고 이에 대한 경험적 자료의 필요성이 중대됨에 따라 컴퓨터 통신망을 이용한 사회조사가 늘어나고 있다. 본 연구는 사이버공간이 보여주는 기술적 기능성을 방법론적으로 검토해 봄으로써 온라인 사회조사의 발전가능성을 탐색하고 있다. 온라인 사회조사는 표집틀, 응답자 접촉방식, 질문지 형태 등에 따라 회원 조사, 방문자조사, 전자우편조사, 전자설문조사로 구분될 수 있으며 기존의 조사방법에 비하여 조사비용의 저렴하고 조사의 실행이 용이하다는 특징을 가지고 있다. 그러나 체계적 오차와 관련하여 온라인 사회조사는 표본설계(모집단의 규정, 표집틀 오차, 추출오차), 측정(측정도구의 구성, 시스템의 안정성과 충실성, 비 응답 및 응답오차) 조사윤리의 측면에서 많은 과제를 안고 있다. 이러한 방법론적인 쟁점에 대한 충분한 고려가 이루어질 때 온라인 사회조사는 본격적인 조사연구의 한 방법으로 자리잡을 수 있을 것이다.

The emerging of cloud data sharing can create great values, especially in multi-cloud environments. However, "data island" between different cloud service providers (CSPs) has drawn trust problem in data sharing, causing contradictions with the increasing sharing need of cloud data users. And how to ensure the data value for both data owner and data user before sharing, is another challenge limiting massive data sharing in the multi-cloud environments. To solve the problems above, we propose a Uniform Encoding and Parsing Framework (UEPF) with blockchain to support trustworthy and valuable data sharing. We design namespace-based unique identifier pair to support data description corresponding with data in multi-cloud, and build a blockchain-based data encoding protocol to manage the metadata with identifier pair in the blockchain ledger. To share data in multi-cloud, we build a data parsing protocol with smart contract to query and get the sharing cloud data efficiently. We also build identifier updating protocol to satisfy the dynamicity of data, and data check protocol to ensure the validity of data. Theoretical analysis and experiment results show that UEPF is pretty efficient.

The purpose of this study examined how post-traumatic stress, caused when internet users in web portal or social media are defamed in cyberspace, influence on coping behaviour, through the Theory of Reasoned Action's two major factors: Attitude on behaviour and subjective norm. In so doing, it aims to provide a technical and political solution that would fundamentally prevent future victims in cyberspace. In an effort to examine its research theory, a survey was conducted on people who have had the experience of being defamed in cyberspace. The results showed, first, hypersensual has no significant influence over attitude on behaviour and subjective norm. Second, intrusion has no significant influence over attitude on behaviour and subjective norm. Third, avoidance showed significant influence over attitude on behaviour and subjective norm. Fourth, attitude on behaviour and subjective norm showed significant influence on behaviour. This study has both theoretical and practical significance; Unlike previous studies on cyber defamation with qualitative research method, this study employed quantitative method through theory-based approach. In other words, the researcher did not arbitrarily set variables, but utilized the Theory of Reasoned Action for examination.

In this paper, a new user identification method is presented using real environmental human-computer-interaction (HCI) behavior data to improve method usability. User behavior data in this paper are collected continuously without setting experimental scenes such as text length, action number, etc. To illustrate the characteristics of real environmental HCI data, probability density distribution and performance of keyboard and mouse data are analyzed through the random sampling method and Support Vector Machine(SVM) algorithm. Based on the analysis of HCI behavior data in a real environment, the Multiple Kernel Learning (MKL) method is first used for user HCI behavior identification due to the heterogeneity of keyboard and mouse data. All possible kernel methods are compared to determine the MKL algorithm's parameters to ensure the robustness of the algorithm. Data analysis results show that keyboard data have a narrower range of probability density distribution than mouse data. Keyboard data have better performance with a 1-min time window, while that of mouse data is achieved with a 10-min time window. Finally, experiments using the MKL algorithm with three global polynomial kernels and ten local Gaussian kernels achieve a user identification accuracy of 83.03% in a real environmental HCI dataset, which demonstrates that the proposed method achieves an encouraging performance.
