The number of climbers in Japanese mountains have increased for recent years, and climbing and hiking have been getting constructive fields in tourism. However, some climbing beginners, especially middle aged and older people, who are overconfident on own physical strength sometimes encounter serious accidents and distresses. Actually, an accident and a distress in a mountain have also increased in these years. In order to achieve safer mountain climbing, it would be effective to aggregate and analyze individual climbing experiences in accordance with not only individual conditions but also mountain environments even if there is poor network connection and power supply. Therefore, this paper aims to organize available datasets for analysis of practical behavior of mountain climbers, and describes methods to obtain climbing behavior data even for middle and older people under poor network and power environment. In particular, we implemented a cloud system to aggregate online-submitted climbing plans, and a check-in app using individual owned IC-cards. Finally, this paper describes some findings and discussions through our field experiments.

This paper reports a robot which interacts with children semi-autonomously in a science room of an elementary school to help children's understanding of science classes. The robot asked children questions related to their science classes during breaks between science classes; children could freely interact with it during experiment periods. We implemented a personal identification function to the robot by using a face recognition system with robot's camera and a human tracking system with environmental sensors. Still, speech recognition is difficult in noisy elementary school environment; therefore we decided to take over speech recognition function by the operator. In this study our result did not show significant effects of the robot existence for helping children's understanding, but we found that children who joined to the robot's quiz more than a certain time increased understanding toward a specific unit.

平常時から継続的に人々の流動や分布を把握することは,様々な分野の基盤情報として需要が拡大しつつある.人々の流動を把握する手段として,屋外においては GPS を利用した衛星測位技術が確立しているが,地下や屋内等 GPS が利用できない場所では,様々な屋内測位手法が提案されており,施設ごとに独立して設置されている.人々の流動や分布の変化を屋内施設 ・ 地下空間に渡って捉えるには,少なくとも施設単位の粒度で位置を特定する必要がある.本論文では東京都内の地下鉄駅を対象に,携帯電話網の通信で参照される基地局セル ID と各地下鉄駅の対応表を作成し,地下鉄利用時の利用駅の推定を試みた.
