Recent cyber attacks are affecting the cyberspace as well as the real world, causing social confusion. Russia Scandal in the US presidential election in 2016 is a representative example. This case is being discussed up to the impeachment of the president. Cyber influence attacks are attacks that affect cyberspace to real space. An effectiveness of such attacks boosts when insiders execute. This study analyzed the keywords related to cyber attacks of Russia during the US presidential election in 2016. Based on this, the paper used sentiment analysis for analyzing the psychology of the current Russian Scandal suspect.

Nowadays, as IT becomes a key element in most business models, it is very important for countries and corporations to create effective business / IT value from IT-related investments. To do so, the process and structure for business / IT value creation must be designed appropriately for the organization's goals and context. For this, the IT governance models that organizations can use typically include COBIT(Control Objectives for Information and Related Technologies) 5, ITIL (IT Infrastructure Library), and TOGAF (The Open Group Architecture Framework). This research helps to use the COBIT 5 Goals Cascade when companies use COBIT 5 to design processes for business / IT value creation. The COBIT 5 Goals Cascade is a mechanism that translates the needs of stakeholders into actionable and customized enterprise goals, IT-related goals and enabler goals. However, this mechanism does not give priority to what goals should be prioritized. According to the COBIT 5 Enterprise Goals to IT-related Goals Mapping table, multiple IT-related goals must be fulfilled to achieve a single enterprise goal. As a result, the IT-related goals for some enterprise goals will be much larger, confusing which goals should be undertaken. To contribute to this problem, this research presents a prioritized methodology that determines the IT-related goals that are more relevant to the organization's goals in realizing IT-related goals. This prioritization methodology is based on the AHP(Analytic Hierarchy Process) using the 'Balanced Scorecard' and 'Governance Objectives' as indicators.

Advances in sensing technology make the task of quantifying expressive human body movement more feasible than ever before. Success will enable breakthroughs in Human-computer interaction (HCI) and control paradigms. In most areas, however, expressivity remains vague and difficult to define. We examine the movements of instrumental conductors at an elementary level to define particular qualities of a beat. In our test case, we focus on the difference between sostenuto and staccato articulation styles as a base for expressive qualities. We show that it is possible to define generic low-level movement features, we call movement primitives, to quantify the qualitative aspects of these two different articulation styles across a range of different tempi. Our movement primitives include the mean and variance of the magnitude of velocity and acceleration, and measures of spatial curvature. Each of these is measured from the ictus of one beat through the ictus of the next beat in a standard 4/4 beat pattern. The discriminative power of these features is demonstrated by two-tail t-tests and verified through Naive Bayes classification experiments. The results demonstrate that our use of movement primitives effectively describes characteristics of expression revealed in each beat of two different articulation styles.

A conductor provides a single unified vision of how to interpret and perform music. However, perceiving a conductor's musical intention and expression is quite challenging as they convey information to performers with subtle, nuanced, and highly individualized gestures. This artwork visualizes the conductor's gestures in order to give the audience a better understanding of its expressivity. To represent the expressivity of the gestures, we created motion profiles over eight frames, at 30 frames per second, and compared them to previously modeled gestures using three motion factors, called Weight, Space and Time from related concepts in Laban Movement Analysis (LMA). Based on this, we have created a real-time, interactive visualization that is driven by the motion factor parameters. The visualization receives the input video stream, and it is transformed into a representation of the three motion factors extracted from the real-time conducting gestures.

The Wikipedia, one of the richest human knowledge repositories on the Internet, has been developed by collective intelligence. To gain insight into Wikipedia, one asks how initial ideas emerge and develop to become a concrete article through the online collaborative process? Led by this question, the author performed a microscopic observation of the knowledge creation process on the recent article, "Fukushima Daiichi nuclear disaster." The author collected not only the revision history of the article but also investigated interactions between collaborators by making a user-paragraph network to reveal an intellectual intervention of multiple authors. The knowledge creation process on the Wikipedia article was categorized into 4 major steps and 6 phases from the beginning to the intellectual balance point where only revisions were made. To represent this phenomenon, the author developed a visaphor (digital visual metaphor) to digitally represent the article's evolving concepts and characteristics. Then the author created a dynamic digital information visualization using particle effects and network graph structures. The visaphor reveals the interaction between users and their collaborative efforts as they created and revised paragraphs and debated aspects of the article.
