Remote-controlled and autonomous driving based on artificial intelligence are key elements required for unmanned combat vehicles. The required capability of such an unmanned combat vehicle should be expressed in reasonable required operational capability(ROC). To this end, in this paper, the requirements of an unmanned combat vehicle operated under a manned-unmanned teaming were analyzed. The functional requirements are remote operation and control, communication, sensor-based situational awareness, field environment recognition, autonomous return, vehicle tracking, collision prevention, fault diagnosis, and simultaneous localization and mapping. Remote-controlled and autonomous driving of unmanned combat vehicles could be achieved through the combination of these functional requirements. It is expected that the requirement analysis results presented in this study will be utilized to satisfy the military operational concept and provide reasonable technical indicators in the system development stage.

The purpose of this study is to examine the patterns of deviation in urban music festival through the theories and a case study. A deviation help contemporary people in the routine of daily life to give a lot of energy. Such a deviation is strongly experienced from the festival. So it is important to study the patterns of deviation in urban festival. For this purpose, the relation between deviation and festival is examined first. And then the patterns of deviation in festival are drawn from the preceding research and case studies. The patterns of deviation in festival are identified as spatio-temporal deviation, active deviation, and situational deviation. Spatio-temporal deviation is divided into non-dailiness, space separation, and space appropriation. Active deviation is divided into make-over and expression. Situational deviation is divided into overturning and new meeting. This patterns of deviation applies to case study of ACC world music festival held in Gwangju metropolitan city with a content analysis methodology. The research finding is that Spatio-temporal deviation is most evident in ACC world music festival, on the other hand active deviation and situational deviation are weak or no evident. It is expected that various deviant elements presented in this study will be used strategically in festival planning to help strengthen the festivity of modern urban festivals.

It is very important issue in information design to improve information efficiency by adapting interesting factors in changing circumstance of information communication. The concept of infotainment is utilized in designing information contents in a way of combining entertainment factors with information itself based on various media and representation technologies. The information arousing user's attention, which includes interesting factors, is persuasive message comppared to the informative message conveying only information itself. The reason why infotainment is persuasive is because it makes the user absorb deeply in the information during the process of understanding by sensorial stimuli, cognitive interest, and situational interest. The sensorial stimuli originates from the expression elements of information design. The cognitive interest from the user's intellectual activities has a try to overcome mental block when user confronts with the redundant expression in the manner of unexpectedness and inharmony. The situational interest originates from user's optimum experience by the flow of satisfaction. Therefore, the attribute of infotainment is defined with the stimuli, the redundancy, and user's satisfaction. Its design elements consist of physical factors, organizational factors, and psychological factors. The physical factors through sensorial stimuli are utilized by visual manipulation such as visual analogy or visual pun, multimedia, and moving expression. The organizational factors through redundant expression bring user's imagination by adapting storytelling, event, and interaction in the process of understanding information. The psychological factors through expression of entertainment interests such as humor, play, and game give users psychological satisfaction with the flow. In conclusion the concept of infotainment can be adapted when the design factors should be integrated with its attributes, or the conveying information should go well with its purpose and characteristics.

Even well trained personnel may fall victim to panic, and a wrong assessment of the situation can turn a small accident into a huge disaster. At the disaster site, the event is commonly broadcasted in real time and is unfiltered. Thus, the commander of the site must be able to accurately assess the scene while not missing out on key considerations. Despite the necessity of good situational assessment, there is barely any research on this topic. This study utilizes METT-TC(Mission, Enemy, Troops, Terrain and weather, Time available, and Civil considerations) which is used by militaries to assess combat situations, and proposes MORT-TAC(Mission, Object, Resources available, Terrain and weather, Time available, Ability, and Civil considerations) as factors to consider in effectively controlling the disaster site. The standard model is used for assessing disaster scenes by applying the Delphi analytical method on each sub-factor of MORT-TAC.

As technology evolves, Internet usage continues to grow, resulting in a geometric increase in network traffic and communication volumes. The network path selection process, which is one of the core elements of the Internet, is becoming more complex and advanced as a result, and it is important to effectively manage and analyze it, and there is a need for a representation and visualization method that can be intuitively understood. To this end, this study designs a framework that analyzes network data using BGP, a network path selection method, and applies it to the cyber common operating picture for situational awareness. After that, we analyze the visualization elements required to visualize the information and conduct an experiment to implement a simple visualization. Based on the data collected and preprocessed in the experiment, the visualization screens implemented help commanders or security personnel to effectively understand the network situation and take command and control.

The present research analyzed the social meaning of Korean clothing in women's magazine. The data were included the advertisements and publicity related to Korean clothing in two women's magazines and condensed at 5 year intervals with content analysis. The identified 276 advertisements and publicity were categorized into four areas. The categories were the trend of exterior growth of advertisements and publicity, appeals and approach, the elements of advertisements and publicity including background, the relation of models, situations, and styles of Korean clothing over times. The results of the study were as Follows: 1. In conjunction with external growth of advertisements and publicity of Korean clothing, the social meaning of Korean clothing has changed from ceremonial clothing to daily-wear clothing. Especially since 1980, the theme of advertisement and publicity of Korean clothing were changed form the beauty of traditional Korean clothing such as grace of dignity to the individuality which was the typical value of western Clothing. 2. The trends of appeals related to Korean clothing and applied Korean clothing have reflected the changing time and society. Since 1980, the emotional or mixed approach with metaphor have increased, whereas factual or situational approach were dominated in 1960s and 1970s. 3.

This study aimed to specify Vessel Traffic System(VTS) operators' situational awareness(SA) tasks and examine differences in subjective ratings for three levels of SA. Data for relative frequencies of SA tasks were collected by using direct in field observation. Subjective rating scores were obtained using a questionnaire method and compared in terms of VTS operator's gender and length of service career. The results are as follows. First, it was found that the VTS operators perform information perception task elements more frequently than those for information integration and prediction. Second, VTS operators tended to show subjectively lower evaluation scores for prediction than information perception or integration. Third, male VTS operators rated their SA ability higher than females. Fourth, the male VTS operators more than 15 years of career service showed higher subjective rating scores than those with under 5 years of service. Female VTS operators with different levels of career service showed a similar level of subjective rating scores. These results suggest that the frequency of SA related tasks and subjective SA evaluation can differ in terms of SA levels and individual differences.

The purpose of this study is to primarily explore the characteristics of 'irony' and focus on the process of visualizing it. 'Irony' is one of the rhetorics used to describe the context or situational aspects of writing. This 'Dépaysement' that appears in art history corresponds to 'ironic' rhetoric in writing. 'Dépaysement' is a combination of techniques, which conveys a message through de-familiarizing rhetoric. With the images conflicting with each other in logic on the same canvas. 'Dépaysement' and 'ironic' rhetoric have commonalities in that they produce a situation with opposite or contradictory images and obscure the images and the situation by distorting them into being different from what has usually been known. In conclusion, Ironic Characteristics and Visual technique elements of dépaysement are identical, this study attempts to understand the visual language by analyzing 'the visual irony' that appears in artworks.

In this paper, we examine work in the evolution of content-based retrieval systems that rely on an intelligent infrastructure. Here, we refer to intelligence as the capabilities of the systems to build and maintain situational or world models, utilize dynamic knowledge representations, exploit context and overage advanced reasoning and learning capabilities. We argue that these elements are essential to producing effective systems for retrieving visual information at semantic levels matching those of human perception and cognition. In this paper, we review relevant research on the understanding of human intelligence and construction of intelligent systems in the fields of cognitive psychology, artificial intelligence, semiotics. We also discuss how some of the principal ideas from these fields lead to new opportunities and capabilities for content-based retrieval systems. Finally, we discribe some of our efforts in these directions. In particular, we present MediaNet, a multimedia knowledge presentation framework that facilitate and enable intelligent content-based retrieval.
