title: Robot Interaction combination of human interaction and machine interaction for the purpose of ongoing dialogue
abstract: In the scene various dementia prevention of elderly, the demand for communication robot that interacts with people is increasing. It wants carry out the ongoing dialogue with the robot to the user, and development have been carried out using behavior and such as eye contact and supportive response, techniques such as natural speech synthesis, but not of the flow of dialogue and dialogue sentence eliminating the naturalness is difficult. In this study, in the dialogue of the robot, to perform a study on sentence generation technology to achieve interactive content attractive and human response.

title: Life Activity Recording Method Using Interactive Character Agent That Change Appearance for the Elderly
abstract: This paper proposes a life logging framework of detail life activity using an interactive character agent for elderly. In order to improve a current health condition, it is necessary to modify behavior of usual life based on life log data which records life activities of the elderly. However, it is still difficult to record the life log of the elderly because of digital divide. The proposed framework records more detail activities by using not only sensors, such as GPS or acceleration sensor etc, but also interaction with character agent. By using interaction with agents, the method can collect purpose or detail action information of usual activities and meal information. In experiments, the life logging system with interaction is developed and we show a feasibility of the system through long term experiments.

title: Examination of the topic classification system with aspect coverage
abstract: It takes labor and time to read data starting writing output in a meeting again. The document classification using the aspect that is the index of the sentence topic classification is performed in the study conventionally, but dividing a simple topic and am a chisel. I examine the classification that the hierarchical structure considered in this study.

発表題目: アスペクト被覆を用いた話題分類システムの検討
発表概要: 会議で出力された書き起こしなどのデータを読み返すのは労力と時間がかかってしまう.従来研究では文章話題分類の指標であるアスペクトを用いた文書分類が行われているが,単純な話題分けのみである.本研究では階層構造も考慮した分類について検討する.

title: Analysis of Software Bugs based on the Ease of Detection
abstract: For quality improvement and cost reduction of software development, it is necessary to detect and fix bugs in an early stage of development. Code review has been conducted in many development to achieve early detection and fixing of bugs. Past studies on code review methods have revealed that the performance of individual reviewers is more dominant than the review methods used by the reviewers. On the other hand, there are few researches on analyzing the characteristics of bugs found by individual reviewers, although bugs themselves greatly affect the review performance. In this study, through an experiment on code review with 69 subjects, we analyze the characteristics of easy bugs (detected by many subjects) and difficult bugs (detected by few subjects). We also analyze the characteristics of reviewers based on the bugs they detected.

発表題目: 発見容易性に基づくソフトウェアバグの分析
発表概要:ソフトウェアの品質向上や開発コスト削減のためには,バグの早期発見と除去が不可欠である. バグの早期発見・除去を達成するため,多くの開発現場でコードレビューが実施されている. これまでに複数のレビュー手法が提案・研究されているが,レビューにおけるバグの検出効率はレビュー手法よりもプログラム理解度の影響が強いことが知られている. 一方で,個々のレビュアーが検出するバグの種類や特徴についての調査は少なく,さらなる研究が必要である. 本研究では,69人の被験者を対象としたコードレビュー実験により,レビューで発見されにくいバグの特徴や,レビュアー間の発見バグにみられる個人差を調査・分析する.

title: A method of dynamic route selection for disaster search with Unmanned Aerial Vehicle
abstract: In a disaster situation, it is difficult to investigate the damage situation from the ground due to the failure of infrastructure. Unmanned Aerial Vehicle(UAV) is widely used to search operation in such a situation. However, flight time of UAV is limited because of the limited battery life. For the purpose of making efficient search route with the restriction of flight time, we propose a dynamic routeing method of UAV search operation based on changing granularity of space-filling curve.

発表題目: 無人航空機による災害救助情報収集時の動的経路決定手法の提案
発表概要: 災害発生時には被害者の救助活動のために速やかな被害状況の調査が必要になる一方で,インフラの損壊により地上からの情報収集活動が困難になる.そういった環境下で必要な情報を収集する手段として無人航空機(UAV)が用いられるが,飛行時間の制約のため探索の範囲が制限される.そこで本研究では空間充填曲線の粒度変更により経路を動的に制御することで制約下でより広範囲の情報を迅速に収集する手法を提案する.

title: A context aware routing metric for reliable route discovery in MANET using fuzzy logic.
abstract: The main objective of Mobile Ad hoc Network (MANET) is to maintain the node's connectivity and ensuring reliable transporting of data packets. The most common metric used for routing in MANETs is "hop-count". However, it is important to choose an appropriate metric that reflects the quality of a path as well. We propose a multi-metric path selection algorithm for MANET. The route metric considers all these features (distance, load, interference, latency, node availability and remaining power) while searching for a path to destination. The proposed protocol uses Fuzzy decision logic based on two parameters (link-quality and link-lifetime) to choose the optimal path among all the available paths in MANET. Extensive simulation will be done to evaluate the proposed method and will be compared with other existing techniques.

title: A dynamic traceback method of DNS amplification attack that forcused on the prior search of OpenResolver.
Attacker node sends victim node a lot of packets in order to plunge it into high load. This attack called DoS or DDoS attack. Recently, attackers change the way of attack. They perform attack using DNS server because it can amplify attack packets easily. This attack called DNS amplification attack. I forcus on OpenResolver. I propose a method to traceback the attacker using the predictive and DNS amplification attack packets.

発表題目: 事前のOpenResolver探索に着目したDNS amplification攻撃における動的な攻撃元特定手法
単一もしくは複数の攻撃ノードが被害ノードに対して大量のパケットを送信し、過負荷に陥れる攻撃としてDoS、DDoS攻撃が挙げられる。近年、その攻撃手法に変化が生じ、攻撃パケットを被害ノードに直接送りつけるのではなくDNSサーバを中継することによって効果的に攻撃パケットを増幅させてから攻撃を行うDNS amplification攻撃が行われるようになっている。そこで本研究ではOpenResolverに着目しDNS amplification攻撃における攻撃パケットと、攻撃の予兆を用いることで攻撃元を探知する手法について提案する。
