인터넷은 본질적으로 신뢰할 수 없는 네트워크들의 집합체이다. 인터넷상에서는 정보의 흐름을 통제하기가 대단히 어렵기 때문에, 산재한 자원을 충분히 활용하면서, 내부의 중요한 자원을 인터넷으로부터 보호해 줄 수 있는 보안문제가 심각하게 대두되고 있다. 최근 발생하는 바이러스 사고와 시스템 불법 침입에 대한 발생률이 과거보다 훨씬 높으며 다양해지고 있다. 이러한 시기에 불법 행동을 막기 위한 침입 차단에 대한 연구가 활발하게 진행 중이며 계속적인 발전을 하고 있다. 본 논문에서는 침입자의 불법 행동에 대한 로그 정보를 XML 포맷 형식에 맞추어 관리자에게 통보하고, 원격으로 제어 할 수 있는 침입 차단 시스템을 개발하여 관리측면에서 발생하는 문제점을 해결하고자 하였다.

초기의 웹(Web)이 비구조적인 문서를 사용함으로써 발생하는 단점인 문서 처리와 교환 및 재사용성에 대한 해결책으로서 W3C(World Wide Web Consortium)에서 1998년 2월에 XML(eXtensible Markup Language)을 제정하였다. XML을 사용함으로써 기존 전자거래는 XML 기반 메시지 교환을 통한 기업간 전자거래 형태로 변화하고 있으며, 이러한 기업간 전자거래에 사용되는 XML 기반의 구조화된 전자문서를 저작할 수 있는 솔루션에 대한 필요성이 대두되었다. 이에 본 논문에서는 XML 문서를 효율적으로 편집 및 저작 할 수 있는 사용자 중심의 XML 인스턴스 편집기와 XML 문서의 구조를 정의하는 XML 스키마 문서를 저작하기 위한 XML 스키마 편집기를 통합한 XML 문서편집 시스템에 관한 연구를 하였다.

Everyone has a voice and can broadcast it to the world. We hear about the old maxim of media do not tell people what to think but what to think about. Under this theory or approach, a key function of political communication is to make the public think about an issue in a way that is favorable to the sender of the message. In a democracy, political communication is seen as crucial for the building of a society where the state and its people feel they are connected. Thus, this is a study on how social media (e.g., Facebook, blogs, and YouTube) were used in the domain of Malaysian politics during the 13th general election campaigning period in order to set the agenda to form public opinion. The study found that Facebook was the most popular social media tool that political parties actively engaged with during the 13th general election campaign period. Apart from that, issues pertaining to the election were significantly highlighted by the political parties in social media, especially Facebook. However, other issues that were also important to the people such as the economy, crime, and education were not sufficiently highlighted during the election campaign period. This indicates that the political parties influence the public on what to think about using social media.

Arts gains a new relation as the new academic area that deals with living organisms and through this technology, it affects everything, such as the body, entity, consciousness and unconsciousness to bring an overall change. Based on this premise, arts require a different interpretation from the previous product-focused interpretation or the analysis focusing on the aesthetics. As the result of arts using the scientific methods, I examined the changes of the arts semantics and how it evolved with what kind of contents and characteristics. The net art with the internet base also form a close relationship with the social and cultural codes. In categorizing the social issues and the topical discussions with semantic factors that evolve from the digital biological perspective, it can be divided into four types of complex interaction, positive feedback negative feedback, and amplification of unsettledness. Based on the characteristics of the multimedia and the interactive reaction, the technique and the imagery amplify the message through a spatial and timely meeting in a mutual repletion. In other words, the emotional communication is used to attempt the messages from the products and the expression in various methods.

The dynamics of communications powered by the Internet, specifically from the increased use of social media, has led marketers to find creative channels to engage with the customers. One of the recent channels, "branded entertainment", is becoming familiar as an advertising strategy in which the content presented is a marketing tool for the advertising of certain brands. The current study examined the case of a branded-entertainment channel and the mechanism of the advertising instrument that leads to purchase intention. The specific purpose of this research is to investigate whether there is evidence of the role of narrative transportation and the fantasy proneness leading towards purchase of the brand advertised. To arrive at the conclusion, the study using web series sponsored by an artificial sweetener brand and employs a quantitative survey to question the audience. The findings contribute toward the understanding of how consumers respond to branded entertainment via video-sharing platforms. It is indicated that the stories presented in the web series can stimulate the audience to fantasize. Thus, the advertising message conveyed through narrative persuasion can form a favorable attitude toward the brand, which leads to intention to purchase. Practical elements are identified along with limitations and future research suggestions.

The main focus of this study is to understand realities of postmodern consumer culture by deconstructing fashion advertisements, Calvin Klein's ck One and cK be. The metaphysics of critical theory, visual and textual analysis are used to deconstructing the ads applying one of the postmodern cultural critics, Baudrillard' s notion of hyperreality. Through deconstructing the ads five postmodern characteristics representing hyperreality were found. First, there is no message regarding functional characteristics of the product offered in the ad, which is far from the modernist's utilitarian Point of view. Hyperreality in Postmodern consumer culture is consumption centered and focuses on the product's symbolic meanings. Second, especially for cK be, the ad uses atypicai, irrelevant models and images, which are introduced as a concept of ‘real people’ rather than the ideal person or body type. Third, there are transformations of the meanings from cK one to cK be such as the notions of globalization and gender which clearly represent ongoing reality in the Postmodern culture. Fourth, there are hidden meaning of hedonism and relativism, which are prevalent in postmodern ideology. Finally, models' bodies are used to convey messages as well as form the ground and figure in the ad that is a significant characteristic of postmodern consumer culture. In conclusion, the study of Calvin Klein's fashion ads supports the notion that advertising mirrors reality in postmodern consumer culture, which is hyperreality.

Multiplexing information over parallel data channels based on RF MIMO concept is possible to achieve considerable data rates over large transmission ranges with just a single transmitting element. Visual multiplexing MIMO techniques will send independent streams of bits using the multiple elements of the light transmitter array and recording over a group of camera pixels can further enhance the data rates. The proposed system is a combination of the reliance on computer vision algorithms for tracking and OOK cell frame modulation. LED array are controlled to transmit message in the form of digital information using ON-OFF signaling with ON-OFF pulses (ON = bit 1, OFF = bit 0). A camera captures image frames of the array which are then individually processed and sequentially decoded to retrieve data. To demodulated data transmission, a motion tracking algorithm is implemented in OpenCV (Open source Computer Vision library) to classify the transmission pattern. One of the most advantages of proposed architecture is Computer Vision (CV) based image analysis techniques which can be used to spatially separate signals and remove interferences from ambient light. It will be the future challenges and opportunities for mobile communication networking research.

Dissolved oxygen, pH, and temperature are the most important factors for fish farming because they affect fish growth and mass mortality of the fish. Therefore, fish farm workers must always check all pools on the farm, but this is very difficult in reality. That's why we developed a control system for smart fish farms. This system includes a gateway, sensor gatherers, and a PC program using LabVIEW. One sensor gatherer can cover up to four pools. The sensor gatherers are connected to the gateway in the form of a bus. For the gateway, the ATmega2560 is used as the main processor for communication and the STM32F429 is used as a sub-processor for displaying LCD. For the sensor gatherer, ATmega2560 is used as the main processor for communication. MQTT (Message Queuing Telemetry Transport), RS-485, and Zigbee are used as the communication protocols in the control system. The users can control the temperature and the dissolved oxygen using the PC program. The commands are transferred from the PC program to the gateway through the MQTT protocol. When the gateway gets the commands, it transfers the commands to the appropriate sensor gatherer through RS-485 and Zigbee.

This study investigated the effects of the chatbot's level of anthropomorphism - closeness to the human form - and its self-disclosure - delivery of emotional exchange with the chatbot through its facial expressions and chatting message on the user's intention to accept the service. A 2 (anthropomorphism: High vs. Low) × 2 (self-disclosure through facial expressions: High vs. Low) × 2 (self-disclosure through conversation: High vs. Low) between-subject factorial design was employed for this study. An online survey was conducted and a total of 234 questionnaires were used in the analysis. The results showed that consumers used chatbot service more when emotions were disclosed through facial expressions, than when it disclosed fewer facial expressions. There was statistically significant interaction effect, indicating the relationship between chatbot's self-disclosure through facial expression and the consumers' intention to use chatbot service differs depending on the extent of anthropomorphism. In the case of "robot chatbots" with low anthropomorphism levels, there was no difference in intention to use chatbot service depending on the level of self-disclosure through facial expression. When the "human-like chatbot" with high anthropomorphism levels discloses itself more through facial expressions, consumer's intention to use the chatbot service increased much more than when the human-like chatbot disclosed fewer facial expressions. The findings suggest that chatbots' self-disclosure plays an important role in the formation of consumer perception.
