Crowd behaviors on cyber underwater environment are often produced in entertainment contents, such as films and games. It is easy for us to come in contact with the scenes appearing a lot of characters as digital films and animation works are increased gradually, owing to developing of computer graphics. Though the processing a scene of crowd and the behavior system of crowd, related to the processing techniques of crowd behavior in cyber space, have been implemented so far, the research for developing the natural crowd behavior simulator can not be still satisfying. In this paper, we designed a realistic and efficient Fish Schooling Behavior Simulator for the contents production of cyber underwater environment, which showed each type of fish behavior in cyber underwater smartly, and which generated the animating the behavior automatically, reducing the time and cost.

As the cyber threats become more sophisticated and intelligent, the cases of cyber-infringement accidents are rapidly increasing. As a result, awareness of the importance of cyber security professionals has led to many cyber security-related educational programs. These programs provided with education curriculum aimed because cyber security workforce and job-based cyber security education research are not properly done. In this study, we developed a new cyber security education curriculum that defines and reflects cyber security personnel and knowledge system. In this study is not composed solely of the education contents related to the defenses emphasized in the existing education curriculum, but developed education curriculum to train a professional and balanced cyber security manpower by adding education contents in the attack field.

The introduction of smart grid, which is an innovative application of digital processing and communications to the power grid, might lead to more and more cyber threats originated from IT systems. In other words, The Energy Management System (EMS) and other communication networks interact with the power system on a real time basis, so it is important to understand the interaction between two layers to protect the power system from potential cyber threats. This paper aims to identify and clarify the cyber security risks and their interaction with the power system in Smart Grid. In this study, the optimal power flow (OPF) and Power Flow Tracing are used to assess the interaction between the EMS and the power system. Through OPF and Power Flow Tracing based analysis, the physical and economic impacts from potential cyber threats are assessed, and thereby the quantitative risks are measured in a monetary unit.

Cyber education has been predicted that it would become the primary education system of 21st century as a way of education focusing on consumers, with the aspect that it seems to be able to satisfy the demand about re-education and lifelong education as the acceleration of fast knowledge accumulation throughout every field of society in the digital era. However, cyber education system has a lot of problems which are for that it lacks of human resources for effective interaction, and it can be disadvantageous to certain type of students with a class environment concentrated on reading and writing and with foundation on computer technology. Therefore, in this thesis, We intended to analyze factors influencing satisfaction of people studying in a situation that cyber education has been required to be a mainstream system of education in the midst of trend of changing paradigm of college education recently, and to suggest some possible solutions for cyber education at university.

In this study, we analysed the current situation of Internet-based insurance services which can provide a non-traditional and cost effective communication channel between the customers and insurance companies. The service of Internet-based cyber-insurance extends from mere advertisement to on-line contracts through planning simulations and, furthermore, to customer monitoring. This cyber-insurance is the demand of the times and is not to be overlooked-by the Korean insurance companies which are suffering from accumulated loss and are facing severe economic depression. We performed a comparative analysis between the domestic cyber-insurance service and pioneers'. Also, we suggested future possibilities of cyber-insurance services, presenting an architecture for the construction of a cyber-insurance management module within the meta financial investment system.

Smart grid (SG) software platforms and communication networks that run and manage the entire grid are increasingly concerned about cyber security. Characteristics of the smart grid networks, including heterogeneity, time restrictions, bandwidth, scalability, and other factors make it difficult to secure. The age-old strategy of "building bigger walls" is no longer sufficient given the rise in the quantity and size of cyberattacks as well as the sophisticated methods threat actor uses to hide their actions. Cyber security experts utilize technologies and procedures to defend IT systems and data from intruders. The primary objective of every organization's cybersecurity team is to safeguard data and information technology (IT) infrastructure. Consequently, further research is required to create guidelines and methods that are compatible with smart grid security. In this study, we have discussed objectives of of smart grid security, challenges of smart grid security, defensive cybersecurity techniques, offensive cybersecurity techniques and open research challenges of cybersecurity.

attention to the elevation of the Quality of living, various ways to revitalize the community spirit are found including reforming hardhearted neighborhoods and overcoming the dreariness of city. With the development of the internet and the spread(dissemination) of "digital home", the communities in cyber space are especially active since we are living in an information-oriented society. To consolidate the communities in apartment complexes, this study tries to find revitalization methods of the cyber community by analyzing the contents of the web sites, understanding the cyber community. The cyber contents that are provided come from three main companies that develop the internet apartments. These are compared and analyzed. The related cyber communities("cafe") are also analyzed. The results are as follows. 1)Though they have some differences on details, the content provided from internet companies can be categorized as introduction to the apartment complex, personal service, community, club and internet shopping. 2)The contents on the cyber community made by the residents are mostly for clubs and chatting since they are made for communication between residents. 3)To revitalize the cyber community, the content that gets more attention from the residents needs to be subdivided into groups.

From the late 20th century, rapidly progressing information communication technology and spreading Internet all over the world cause many reverse functions when there is a conversion into the new information society. One of them is cyber terrorism as cyber crime. Cyber terrorism gradually has had a serious problem in the national security as well as the domestic aspects. Therefore, this study looked into the present condition of cyber terrorism, discussed its prospect, and sought the efficient national countermeasure methods against cyber terrorism by comparing other countries' countermeasure systems currently.

Data of 650 college students in the nation were collected by mail in 2001 Nov. Students preference over cyber communication methods were SMS message, messenger, blog, e-mail in that order. Younger students prefer SMS messages while older students prefer e-mail in relative term. Mobile phone is used more for SMS message than voice communication which is more so with females. The rate of non e-mail use is 57.8%, particularly males(61.9%) and younger students(69.4%) are higher. E-mail, once was very high in use, is being replaced by new media. Suggestion for e-learning environment are being connected, immediacy, active use of blog, more use of fun multimedia information.
