Title Alternative Design and Implementation of e-Learning System at the Faculty of Science, Okayama University
FullText URL cted_002_120_125.pdf.pdf
Author Yamakawa, Junji| Shibata, Tsugio|
Abstract 岡山大学理学部ではe-ラーニングシステム(理学部LMS)が導入され運用されている。理学部LMSの導入に際しては商用またはオープンソフトウェアの様々な学習管理システムを調査し,Moodleが採用された。理学部でのMoodleはセキュアで信頼性の高いPCベースのGNU/Linux,Apache,MySQLおよびPHPが稼動するコンピュータによって運用されている。理学部LMSを使用するための初期コストは,学部を構成している教員と学生の持つ利用能力に応じて可能な限りコストパフォーマンスを高める様にデザインされた。LMSとして採用したMoodleがベースとしている社会構築主義は講義を改善する強力なポテンシャルを有するが,理学部LMSシステムの有効性はユーザの能力によって制限されるかもしれない。

Title Alternative KED estimated distribution of Earth Scientific Information
FullText URL esr_018_1_001_003.pdf
Author Yamakawa, Junji| Ebi, Takahiro| Matsumoto, Hirofumi|
Abstract KED, the Kriging with External Drift, is one of the spatial statistical method for estimating some distribution from the discrete spatial sampled data set about the research field. The KED uses the kriging method (Matheron, 1973) with some auxiliary map to minimize the estimated error. The KED procedure was performed by the R-Language (Ihaka and Gentleman, 1996) using some geostatistical libraries. The auxiliary maps required by the KED were prepared by the authors with some GIS applications. The 3-dimensional geographic representations for the estimated distribution were performed by the Google Earth (Google, 2011). In this report, the KED was applied to some Earth scientific information to show the fundamental scheme of the method.

Title Alternative Representation of Earth scientific information by the Google(TM) Earth
FullText URL esr_017_025_026.pdf
Author Yamakawa, Junji| Ebi, Takahiro| Matsumoto, Hirofumi|
Abstract The Google(TM) Earth is a GIS application provided by the Google, with versatile and high performance visualization and manipulation capability for geographic information. The Google Earth is also a multi-platform application, so the installation and running cost for research and education site is relatively low. The Earth scientific information also have a geographic information scheme, so the Google Earth has some potential to support the education and research field of the Earth science. In this report, some Earth scientific information were converted by the R-Language and its libraries for represent by the Google Earth. The 3-dimensional representation of the information will be able to support to understanding the specification of the data for the Earth scientific research and education field.

Title Alternative DGEM: Digital Geological Elevation Model
FullText URL esr_017_021_023.pdf
Author Yamakawa, Junji| Ebi, Takahiro| Matsumoto, Hirofumi|
Abstract DGEM, a Digital Geological Elevation Model, was developed using the digital geological map and the JPGIS DEM data with some GIS application and the R-Language. In the model, the information of the geological map was combined with the DEM by their coordinates. The integration of those two digital map was performed by the R-Language, so the model can be used by some useful presentation library of the language, such as the RGL, or by some geographical calculation libraries. Moreover, the DGEM will be used by the spatial statistical libraries of the R-Language to investigate some geological spatial distributed specifications.

Title Alternative Native gold from Mikawa mine, Niigata Prefecture, Japan
FullText URL ESR_7_19.pdf
Author Yamakawa, Junji| Tanabe, Mitsuo| Shimada, Kazumasa| Henmi, Chiyoko|
Abstract Native gold was found at Mikawa mine, Niigata Prefecture, Japan. The mineral was associated with quartz in a druse within quartz-vein in propyrite. The crystals were formed in filiform, reticulated and dendritic shapes with about 1 mm length with 0.1 mm width and 0.05 mm thickness. Very malleable and ductile, opaque and yellow with metallic luster. Qualitative and semi-quantiative analyses were performed by the wavelength dispersive EPMA. Quantitatively, the crystals contained Au, Ag and Hg. Semi-quantitative analyses were executed with ZAF correction algorithm. The results showed that these specimens had a average chemical composition Au0.77 Ag0.11Hg0.12. This specimen was archived at our site with a collection number ESO-M01001.
