The purpose of this paper is to make sure of identity as a paradigm of new fsahion to introduce the concept of Sumulacres by J. Baudrillard, For converting to new aesthetic value. To do this, we started observing the general concept of Simulacres, and examined Cyberpunk within thinking of Simulacres and Cyberpunk fashion at virtual space, and then divided aesthetic consciousness appeared at Cyberpunk fashion centering on the concept of Simulacres into inwards sense and outwards sense. Cyberpunk is understood to be one of tendency in the cyber cultures controlled by computer and electronic technology. It is not yet defined clearly and therefore ambiguous and still being elaborated. However, the form started changing our sense sinking into overall cultures in the World, including even movie, literature, music and fashion, and giving complex, deep cultural and artistic possibilities. Also, as a subculture, Cyberpunk is building its own cultural territory in cyber space and is experiencing more real Simulacres than that of it in the ordinary life.

CPS(Cyber Physical System)는 사이버 세계(cyber world)와 물리적 세계(physical word)를 연결하여, 현실과 사이버의 정보를 융합 분석하고, 분석한 데이터를 현실에 Feedback 하는 자동적이고 지능적인 제어 시스템이다. 이러한 CPS는 빅데이터를 분석하여 사용자에게 알맞은 정보를 제공해 주며 딥러닝(Deep Learning)을 통해 정확하고 세밀한 Feedback을 제공하는 등 이종 복합 시스템 간의 고신뢰성과 실시간성을 보장하는 무결점 자율 제어 시스템으로 주목 받고 있다. 실생활에서는 의료, 헬스케어, 교통, 에너지, 홈, 국방, 재난대응, 농업, 제조 등에서 폭 넓게 사용되고 있다. 해외에서는 이와 같은 CPS를 이용해 한 분야에 세밀하게 접목시켜 발전을 도모하며, CPS에 의해 변혁되는 데이터 구동형 사회를 준비하고 있다. 하지만, 이러한 CPS를 사용할 때, 보안의 문제점으로 대규모 정전사태가 발생하고, 생명을 위협하는 등의 취약점 또한 드러나고 있어 이에 대한 보안의 중요성과 CPS의 적용분야를 파악하여 전반적인 보안 문제점을 분석하고자 한다.

Recently. internet applications for efficient cyber education have drawn much interests. The world-wide web provides new opportunities for cyber education over the internet. In this paper, we developed the internet-based educational simulator for design and virtual experiment of the digital logic circuits. The proposed simulator provides the improved learning methods which can enhance the educational efficiency in digital theory. If the students execute the Digital simulator on the web. they can simulate in digital circuits through simple mouse manipulation. The proposed digital simulator can be used so that the students can easily understand the well-known digital principles.

Recently, the effort of enterprises are visualized to correspond for 4th industrial revolution and climate change. Reaching the operation of industrial facilities are one of these efforts and is actively progressing under identical condition between real and virtual world through introduction of cyber-physical system (CPS). However, the problem on no unified definition for CPS still exists. Thus, in this paper, we review the previous concept of CPS. We propose new concept of CPS with four sections such as real world section, communication section, virtual world section and management section. We also propose definite concept by classifying the layer of each section. In order to confirm the possibility of application for proposed concept of CPS, we applied simple motor. We compare the result for torque between real motor and virtual motor. Finally we confirm that the applicability of proposed concept of CPS is very high.

This study compares the influence of perceived public opinion on Internet users' willingness to expression in real space with in cyber space. In real space, people who perceive their opinions as minority opinion are reluctant to express theirs publicly because of fear of isolation. But cyber space is the anonymous world. So we can expect that people express their opinions freely without the fear of isolation in this space. This study's results provide the support for our expectation. In cyber space, the minority perception group has as the high willingness to expression of their opinion about the abrogation of the Korean Family Rights Raw as the majority perception group. Both of in cyber space and in real space, it is the perception failure group that makes discrepancy in the willingness to expression. This group has the lowest willingness to expression in both space. However, the other predictors of willingness to expression in cyber space are similar to those in real space. Issue salience, Communication apprehension, and Age are the very significant predictors of willingness to expression in both spaces. Sex and ideology are significant predictors in real space, while the frequency of online conversation is the significant predictor in cyber space.

Today, the rapid advance of scientific technologies has brought about fundamental changes to the types and levels of terrorism while the war against the world more than one thousand small and big terrorists and crime organizations has already begun. A method highly likely to be employed by terrorist groups that are using 21st Century state of the art technology is cyber terrorism. In many instances, things that you could only imagine in reality could be made possible in the cyber space. An easy example would be to randomly alter a letter in the blood type of a terrorism subject in the health care data system, which could inflict harm to subjects and impact the overturning of the opponent's system or regime. The CIH Virus Crisis which occurred on April 26, 1999 had significant implications in various aspects. A virus program made of just a few lines by Taiwanese college students without any specific objective ended up spreading widely throughout the Internet, causing damage to 30,000 PCs in Korea and over 2 billion won in monetary damages in repairs and data recovery. Despite of such risks of cyber terrorism, a great number of Korean sites are employing loose security measures. In fact, there are many cases where a company with millions of subscribers has very slackened security systems. A nationwide preparation for cyber terrorism is called for. In this context, this research will analyze the current status of Korea's cyber security systems and its laws from a policy perspective, and move on to propose improvement strategies. This research suggests the following solutions. First, the National Cyber Security Management Act should be passed to have its effectiveness as the national cyber security management regulation. With the Act's establishment, a more efficient and proactive response to cyber security management will be made possible within a nationwide cyber security framework, and define its relationship with other related laws. The newly passed National Cyber Security Management Act will eliminate inefficiencies that are caused by functional redundancies dispersed across individual sectors in current legislation. Second, to ensure efficient nationwide cyber security management, national cyber security standards and models should be proposed; while at the same time a national cyber security management organizational structure should be established to implement national cyber security policies at each government-agencies and social-components. The National Cyber Security Center must serve as the comprehensive collection, analysis and processing point for national cyber crisis related information, oversee each government agency, and build collaborative relations with the private sector. Also, national and comprehensive response system in which both the private and public sectors participate should be set up, for advance detection and prevention of cyber crisis risks and for a consolidated and timely response using national resources in times of crisis.

The virtual world is a cyber gaming space where a player interacts with others through their avatars. It is now mainly developed in foreign countries including USA, Canada, and Europe and many experts say that the market capacity of virtual world will be continually expanded in worldwide. The virtual world will mostly be made such that a user accesses the world for free and pays for in-game activities. But it is hardly that we find the effective methodology of payment system for such virtual world due to its' short development history. In the case of Korea, various payment methods of selling in-game assets have been tested in online games. The paper propose an effective revenue model for social virtual world focused on selling in-game assets. The guideline of the proposed revenue model will be expected to contribute creating revenue focused on selling in-game assets, effectively for social virtual world.

Until now, we have believed that one of advantages of cyber market is that it can virtually display and sell goods because it does not necessary maintain expensive physical shops and inventories. But, in a highly competitive environment, business model that does away with goods in stock must be modified. As we know in the case of AMAZON, leading companies already consider merchandise management as a critical success factor in their business model. That is, a solution to compete against one's competitors in a highly competitive environment is merchandise management as in the traditional retail market. Cyber market has not only past sales data but also web log data before sales data that contains information of path that customer search and purchase on cyber market as compared with traditional retail market. So if we can correctly analyze the characteristics of before sales patterns using web log data, we can better prepare for the potential customers and effectively manage inventories and merchandises. We introduce a systematic analysis method to extract useful data for merchandise management - demand forecasting, evaluating & selecting - using web mining that is the application of data mining techniques to the World Wide Web. We use various techniques of web mining such as clustering, mining association rules, mining sequential patterns.
