DETECTING FORESTS DAMAGED BY PINE WILT DISEASE AT THE INDIVIDUAL TREE LEVEL USING AIRBORNE LASER DATA AND WORLDVIEW-2/3 IMAGES OVER TWO SEASONS
No full textPine wilt disease is caused by the pine wood nematode (Bursaphelenchus xylophilus) and Japanese pine sawyer (Monochamus alternatus). This study attempted to detect damaged pine trees at different levels using a combination of airborne laser scanning (ALS) data and high-resolution space-borne images. A canopy height model with a resolution of 50 cm derived from the ALS data was used for the delineation of tree crowns using the Individual Tree Detection method. Two pan-sharpened images were established using the ortho-rectified images. Next, we analyzed two kinds of intensity-hue-saturation (IHS) images and 18 remote sensing indices (RSI) derived from the pan-sharpened images. The mean and standard deviation of the 2 IHS images, 18 RSI, and 8 bands of the WV-2 and WV-3 images were extracted for each tree crown and were used to classify tree crowns using a support vector machine classifier. Individual tree crowns were assigned to one of nine classes: bare ground, Larix kaempferi, Cryptomeria japonica, Chamaecyparis obtusa, broadleaved trees, healthy pines, and damaged pines at slight, moderate, and heavy levels. The accuracy of the classifications using the WV-2 images ranged from 76.5 to 99.6 %, with an overall accuracy of 98.5 %. However, the accuracy of the classifications using the WV-3 images ranged from 40.4 to 95.4 %, with an overall accuracy of 72 %, which suggests poorer accuracy compared to those classes derived from the WV-2 images. This is because the WV-3 images were acquired in October 2016 from an area with low sun, at a low altitude.ArticleThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences.XLII-3/W3:181-184(2017)journal articl
キーポイントパッチ抽出法を用いた高能率な進化計算による3次元点群レジストレーション
No full text3次元点群のレジストレーションは，モデリングやオブジェクト認識などの応用技術の前処理としてよく使われる．進化計算による方式は，初期位置に依存せず高精度にレジストレーションできるという特長をもつが，他の方式と比較して計算量が大きいという問題がある．この原因は，評価関数を求めるための最近傍探索回数が多いためと考えられる．探索回数の削減には点群のリサンプリングがよく用いられるが，これはレジストレーション精度が低下することが多い．そこで，キーポイントの周囲の点のみを抽出した点群(キーポイントパッチ) を進化計算によるレジストレーションに用いる手法を提案する．また，更なる高精度化及び高速化を実現するため，境界の活用によるオクルージョンの悪影響の低減，キーポイントパッチの個数削減，キーポイントパッチのリサンプリングによる点数の削減を提案する．8種類のデータセットを用いた実験結果から，提案方式は従来方式と比較して，レジストレーション精度を維持しつつ約100倍以上高速化できることを確認した．Article画像電子学会誌.47(2):154-166(2018)journal articl

Fabrication of Copper/Multiwalled Carbon Nanotube Composites Containing Different Sized Nanotubes by Electroless Deposition
No full textCu/multiwalled carbon nanotube(MWCNT) composites containing two different sized MWCNTs were fabricated using an electroless deposition technique in aqueous solution. In order to disperse the MWCNTs in the solution, an anionic dispersant of sodium dodecyl sulfate (SDS) and a polymeric dispersant of hydroxypropyl cellulose (HPC) were used. The dispersibility of the MWCNTs in solution was evaluated by measuring the particle size distribution. The zeta potential for the MWCNTs was also evaluated to examine the dispersibility. Uniform Cu/MWCNT composites containing the two different sized MWCNTs were fabricated through the electroless copper deposition process from a solution containing copper ions, a complexing agent, a reducing agent, and two dispersants, SDS and HPC, in addition to the two different sized MWCNTs.

Communication-Fabrication of a Uniformly Tin-Coated Three-Dimensional Copper Nanostructured Architecture by Electrodeposition
No full textA three-dimensional copper nanostructure architecture (3DC1) coated uniformly with a tin film was fabricated by electrodeposition. In these trials, a pyrophosphate bath was used for tin plating, and the effects of polyethylene glycol and formaldehyde additives on the morphology of the deposited tin were investigated. Relatively large tin particles were electrodeposited in an inhomogeneous manner over the 3DC1 surface when using a plating bath without additives. In contrast, 3DC1 coated with a uniformly thick tin film was fabricated by employing a bath with the additives. (C) The Author(s) 2015.

Fabrication of Three-Dimensional (3D) Copper/Carbon Nanotube Composite Film by One-Step Electrodeposition
No full textA three-dimensional (3D) composite film containing copper nanostructures and carbon nanotubes (3DC/CNT composite film) was fabricated by one-step electrodeposition. The 3DC/CNT composite film was formed under galvanostatic conditions using a copper sulfate bath containing CNTs and polyacrylic acid which acts as both a 3DC-forming and a CNT-dispersing agent. The composite film consists of thin copper sheets with thicknesses of ca. 70-80 nm and CNTs, with large interior spaces between sheets. The CNTs were homogeneously distributed inside the composite film and were fixed by the copper sheets where CNTs pierce the copper sheets. The CNT content in the composite films increased with the CNT concentration of the plating bath. The 3DC film without CNTs did not maintain its 3D spaces when the film thickness was increased due to insufficient structural strength, whereas the 3DC/CNT composite film maintained the 3D spaces despite an increase in film thickness, which suggests that the CNTs reinforce the film to maintain the 3D spaces.

The relationship between 4 patterns of PM leadership behavior and work motivation was statisticallyexamined.Results and Discussion: Curriculum coordinators were classifi ed into the following patterns: PM-type（n=36）which represents both higher performance and maintenance, Pm-type（n=30）which represents higher performance and lower maintenance, pM-type（n=29）which represents lower performance and higher maintenance, and pm-type（n=28）which represents both lower performance and maintenance. In a comparison of the mean scores for PM leadership behavior with the mean subscale scores for work motivation, current and potential work motivation showed pm＜Pm＜PM＜pM and pm＜Pm＜pM＜PM, respectively. The high motivation for PM and pM types was thought to be related to the performance of M function.Conclusion: Among curriculum coordinators, a relationship existed between PM leadership behaviorConclusion: Among curriculum coordinators, a relationship existed between PM leadership behavior and work motivation.

妊婦の足型と常用靴の実態、および足型と妊娠中の不快症状との関連
No full text本研究の目的は、妊婦の足型と常用靴の実態および足型と妊娠中の不快症状の関連を明らかにすることである。妊婦健康診査の受診または両親学級への参加を目的として来所した妊婦を対象に、妊娠中の不快症状や常用靴について問う自記式質問紙調査、足裏測定装置による足型測定、FOOT GAUGE及びメジャーによる足長・足幅・足囲測定を実施し、113名のデータを分析した。その結果、77.9％の妊婦が踵部分を覆う靴を、18.6％の妊婦がサンダルを常用靴としており、妊娠判明後に3㎝以上のヒールがある靴を履いている者はいないことが明らかとなった。また、49.6％の妊婦に足型異常があり、浮き趾が最も多い足型異常であること、浮き趾がある者は浮き趾がない者と比べ、足がつりやすいことが明らかとなった。今後は、妊娠に伴う腹部増大が生じる前後における足型の変化を縦断的調査し、関連要因を検討していく必要があると考える。The study aims to clarify the relationship between the foot type of pregnant women and the actual status of regular shoe usage as well as the relationship between foot type and symptoms of discomfort during pregnancy. The procedures performed on pregnant women who visited the clinics to receive a medical examination or to participate in parenting classes are described below. Clients were provided a self-administered questionnaire that asked about the symptoms of discomfort during pregnancy, and the use of regular shoes; foot type measurements were obtained using a sole measuring device. In addition, the measurements of foot length, width, and circumference were obtained using a foot gauge. In all, data from 113 participants were analyzed. Overall 77.9% pregnant women wore shoes that covered the heel, 18.6% wore sandals as their regular shoes, and none wore shoes with heels higher than 3㎝ after learning of their pregnancy. In addition, foot type abnormalities were present in 49.6% of pregnant women, and the most common foot type abnormality was fl oating toes. Moreover, the participants with fl oating toes had leg cramps more frequently, compared with those without this abnormality. In the future, it will be necessary to assess the changes in foot type before and after increases in abdomen size with pregnancy over time, and to evaluate the related factors.departmental bulletin pape
