This paper introduces a method for colourizing the black and white (B/W) air photos by transferring colour information from another colour air photos that capture the same vegetations at the same season. Air photos taken by U.S. Air Force just after WWII were the first ones that cover whole Japan. As they are available only in B/W, the imagery has not been fully utilized.In our method, land cover was roughly categorized on a B/W image, whereas colour information for each category was taken from colour source images. Then colour information and original intensity information of the B/W image were combined in the HSI colour space.A questionnaire on photo interpretation experts revealed that the proposed method worked well for the photos. Additionally, rough categorization was enough for the method and the colourized photos might improve interpretation efficiency. The colourized images should be used for various purposes such as 3D landscape visualisation.

The various kinds of the electric personal mobility, which is one or two-seater, are being developed all over the world. These mobilities are applied into the substantiative experiment held in the several cities in order to investigate the effectiveness and popularity. The main specification of the personal mobility is the small footprint to reduce the parking space and alleviate traffic jam. However, the small footprint causes the deterioration of the posture stabilization. The authors are developing the personal mobility, which has a lean actuator to tilt the upper body for keeping the posture stabilization not only during turning motion but also on the uneven road surface. In this paper, the motion model considering yaw motion around roll axis is derived. In addition, the posture control method based on the motion model is proposed to realize the desired roll angle, which ensures the required range of the zero moment point. The effectiveness of the proposed approach is verified by the experiments using a prototype.

Introduction:Recently, it has been suggested that water ice might be present in the lunar polar region based on spectral measurements of artificial-impact-induced plumes in the permanently shadowed region, and remote sensing observation of the lunar surface using a neutron spectrometer [1], [2] and visible to infrared spectrometer [3]. In addition to the scientific interest about the origin and concentration mechanism of the water ice, there is strong interest in using water ice (if present) as an in-situ resources. Specifically, using water ice as a propellant will significantly affect future exploration scenarios and activities because the propellant generated from the water can be used for ascent from the lunar surface and can reduce the mass of the launched spacecraft of lunar landing missions.However, currently it is unclear if water ice is really present in the polar region because of the currently limited available data. Therefore, we need to learn that by directly measuring on the lunar surface. If there is water ice, we also need to know it’s quantity (how much), quality (is it pure water or does it contain other phases such as CO2 and CH4), and usability (how deep do we need to drill or how much energy is required to derive the water) for assessing if we can use it as resources. Therefore, JAXA is studying a lunar polar exploration mission that aims to gain the above information and to establish the technology for planetary surface exploration [4]. JAXA is also studying possibility of implementing it within the framework of international collaboration with Indian Space Research Organisation (ISRO).Spacecraft configuration:The spacecraft system comprises a lander system and a rover system. The system does not have a communication relay satellite but is based on direct communication with the Earth. The minimum target for the landing payload mass is several-hundred kilograms. The launch orbit is the lunar transfer orbit (LTO). After the spacecraft reaches the Moon it is inserted into a circular orbit having a 100km altitude via a few orbital changes. During powered-descent phase, the position of the lander is estimated by landmark navigation using shadows created by the terrain. After landing, the rover is deployed on the lunar surface using ramps. The rover then prospects water ice with its observation instruments..Spacecraft configuration:The spacecraft system comprises a lander system and a rover system.

Also, slope and the simulated communication visibility map from the Earth are created. These conditions can be superimposed to select the landing site candidate.Current status:Recently, we finished joint mission definition review (JMDR) with ISRO, in which JAXA provide a launch rocket and a rover while ISRO provide a lander system. Related to the instruments which will be carried on the rover or the lander, JAXA selected several candidate instrument study teams for accelerating development of these instruments. In this presentation, we are going to introduce current status of the mission planning.References:[1] Feldman W. C. et al. (1998) Science, 281, 1496-1500.[2] Sanin A. B. et al.

保育園児を対象に、色変わりチューインガムを用いて咀嚼力測定を行い、咀嚼力の違いと児の属性、食事の状況、子どもの咀嚼に対する保護者の意識等との関係を調べた。兄弟・ 姉妹数が2人よりも1人または3人以上の児、また女児より男児の咀嚼力が高い傾向にあっ た。咀嚼力が高い児は硬い食品から軟らかい食品まで幅広く食べていたが、咀嚼力が低い児は、軟らかい食品に偏り気味であった。今回の試みは、児の噛むことへの関心を高め、また保護者自身や子どもの咀嚼や食に関する意識を変え、咀嚼力を高める取り組みを促す 効果があったと考える。

船底塗料などとして使用されてきた有機スズ化合物(トリブチルスズ(TBT)及びトリフェニルスズ(TPT))によって,ごく低濃度で特異的に誘導される腹足類のインポセックスのわが国における経年変化と現状の概略を種々の野外調査結果などに基づいて記述した.1990~1991年の汚染レベルに比べると近年の海水中の有機スズ濃度は低減したと見られるものの,イボニシの体内有機スズ濃度の低減率は海水中のそれよりも緩やかであり,またその低減率が海域により異なっていた.また環境中の有機スズ濃度の相対的な減少が観察されるものの,イボニシのインポセックス発症閾値をなお上回る水準であるため,インポセックス症状については全国的に見ても,また定点(神奈川県・油壺)観察による経年変化として見ても,十分な改善が認められなかった.この背景には,国際的には大型船舶を中心になお有機スズ含有塗料の使用が継続していることとともに,底泥からの再溶出の可能性及びイボニシの有機スズに対する感受性の高さなどが関連していると推察された.

Wikipedia, a collaborative Wiki-based encyclopedia, has become a huge phenomenon among Internet users. It covers a huge number of concepts of various fields such as arts, geography, history, science, sports and games. As a corpus for knowledge extraction, Wikipedia's impressive characteristics are not limited to the scale, but also include the dense link structure, URL based word sense disambiguation, and brief anchor texts. Because of these characteristics, Wikipedia has become a promising corpus and a new frontier for research. In the past few years, a considerable number of researches have been conducted in various areas such as semantic relatedness measurement, bilingual dictionary construction, and ontology construction. Extracting machine understandable knowledge from Wikipedia to enhance the intelligence on computational systems is the main goal of "Wikipedia Mining," a project on CREP (Challenge for Realizing Early Profits) in JSAI. In this paper, we take a comprehensive, panoramic view of Wikipedia Mining research and the current status of our challenge. After that, we will discuss about the future vision of this challenge.

目的:日本における高齢者が健康に独居生活を送れる条件を検討する。方法:『医中誌Web』で検索し,18件を分析対象文献とした。結果:高齢者自身の条件である〔個人の特性〕〔意図した活動〕〔日常生活活動の維持〕と,高齢者を取り巻く条件である〔孤独との向き合い方〕〔安心できる生活環境〕が抽出された。高齢者が健康に独居生活を送る記述内容は,19の身体的健康,20の精神的健康,27の社会的健康に分類された。結論:高齢者自身の条件は,生活習慣や価値観などは個々で大きく異なるため,高齢者自身が物事を能動的に決定できることが健康な生活の継続に関係していると推察された。また,高齢者を取り巻く条件は,他者との関係性や生活環境が要因になると考えられた。さらに,社会的健康が多く分類されたことから,高齢者が健康に独居生活を送るためには人や社会とのつながりが重要であることが示唆された。
