title: Proposals of Cyber Security Exercise Tools for Improving Security Management Skill
abstract: The shortage of cybersecurity personnel is a major problem which is exacerbated by the increasing number of cyber attacks and the possible demotivation of the said personnel. While the lack of personnel could be fixed by training more people, in the meantime, it is important to maintain motivation among the cybersecurity team members of a given organization in order for them to appropriately respond to the changing and evolving cyber attacks. In order to overcome the above problems, we propose cyber game exercise tools, which focuses on areas hitherto uncovered on existing cyber game exercises. To validate our tools, we conducted cyber game exercises and evaluated the achievement of the design policy by analyzing the participants questionnaire results. The analysis showed that our tools are useful. language of the presentation: Japanese | |||

title: Preference-aware Video Summarization for Development of Tour Video Curation System
abstract: Recently, there are increasing demands for tour recommendations using videos because more tourists search and watch tourism videos when planning a sightseeing tour. However, searching desired videos are very hard (even not possible) or require significant labor. In addition, since each searched video is on a fixed route, it is necessary to search other route videos when it does not match the use's desire. In this study, we propose a system for curating a tour video adjusted to the intention or preference of each individual user from consumer generated media (CGM) including videos, photos and comments posted on each sightseeing spot/route through Social Networking Service. This system creates a tour route based on user's preference and a summarized video along the route. For creation of a summarized video, we propose a video summarization algorithm that maximizes viewing satisfaction within a specified playback time. Users can plan favorite a tour easily by watching this summarized video. In order to evaluate effectiveness of our method, we compared watching a summarized video with searching by Internet. As a result, we found that watching a summarized video can help a user imagine a tour easily, improve sightseeing and increase his/her satisfaction. language of the presentation: Japanese | |||

title: Predicting occurrence timings of daily living activities through a time series data analysis
abstract: Recently, various home services are being provided such as smart appliance control with energy saving taking into account the position of residents and elderly monitoring through human positioning and activity recognition technologies. We believe that is important to predict activities in the future to provide more sophisticated home services. For activity prediction, considering temporal dependency between activities is especially important. Therefore, we employ Long Short Time Memory (LSTM) of the DeepLearning algorithm to analyze time series of data acquired in smart home. We propose 2 classification methods for prediction of activities. The first model is a multi-class classifier for different activity occurrence timings. This model could predict some specific activities such as eating at a reasonably good recall. However, most activities were not predicted accurately because of many classes of occurrence timings. The second model is a binary classification on whether the activity occurs or not before the specified time. This model could predict most activities with better recall than the first model. language of the presentation: Japanese | |||

title: Investigating User Reactions to Interactive Signage Aiming to Promote Behavior Change
abstract: In recent years, many research and developments of behavior change have been conducted. The purpose of behavior change is to improve people's lifestyle pattern or to maintain the improvement for a long time aiming to achieve a goal of promoting health condition improvement. In order to achieve the foundation of a new lifestyle, it is necessary to recognize the daily life patterns of users and give triggers to users in their daily life for behavior change. To realize this, in this study, we construct an interactive signage which is able to positively talk to the passing user and try to induce behavior change by sending visual stimulation and auditory stimulation. In this paper, we report the result of the investigation on users' reactions and feelings to the proposed interactive signage. As a survey experiment, we set up 4 interactive signage on a floor of our university and asked 15 participants to carry a name tag with a BLE beacon during their daily life. There are 4 different dialogue scenarios and a scenario is posted to the participants when he/she approaches the interactive signage. Participants can respond to these scenarios through a touchscreen. Based on the result of the experiment, it is found that the interactive signage can induce behavior change effectively. language of the presentation: English | |||

title: Reducing power comsumption of phase encryption module using two stage mapper
abstract: Recently,RFmodule that consume low power and communicate wide area for IoT(Internet of things).We adopt "phase encryption" to RFmodule's cypher section."Phase encription" is method that encrypt after modulation and it is safer than typical encription(encrypt before modulation).But Phase encription's cirquit is too complexity and high power consumption.For reduce circuit's power comsumption and area,We improve fhase encription circuit using two stage mapper. language of the presentation: Japanese | |||

title:Design of state observer with signal losses
abstract:In sampled-data controlling systems, there could occur transmission loss when using a contactless measuring instrument or network communication channels. It makes sampling rates aperiodic, which causes the system problems such as estimation values of system's states diverge with a periodic design of observer. To prevent this problem,I propose the design of aperiodic sampling observer with round-robin scheduling switching its gain depending on the sensor and the elapsed time since the last sampling of measurement signal. I also execute the simulation of state estimation for a linearized drone system using proposed observer to show effectiveness. language of presentation: Japanese | |||

title: Distbituted Agreement over Activity-Driven Networks
abstract: In this research, we investigate asymptotic properties of a consensus protocol taking place in a class of temporal (i.e., time-varying) networks called the \emph{activity-driven network}. We first show that a standard methodology provides us with an estimate of the convergence rate toward the consensus, in terms of the eigenvalues of a matrix whose computational cost grows exponentially fast in the number of nodes in the network. To overcome this difficulty, by focusing on the regime of sparse networks, we then derive an alternative bound involving the eigenvalues of a matrix that is easy to compute. We confirm our theoretical results by numerical simulations. language of presentation: Japanese | |||

title: Optimal Resource Allocation for Epidemics using Random Matrices
abstract: We study the problem of containing epidemics in directed networks by distributing protection resources. In previous work, it is assumed that the network structure is known. However, network structure of human relations and air transportation which is used to optimize resource allocation may be unknown or too large to use. Therefore, we introduce random matrices to treat edges of network as random variables. Using this method, we set the optimization problem for preventing infection from spreading. We illustrate our theoretical result using human relation network. language of presentation: Japanese | |||
