Characteristics and distribution of stone monuments at the Higashi-Hiroshima Campus of Hiroshima University

本研究では，広島大学東広島キャンパスを対象として，悉皆調査によりすべての石碑の分布や属性，特徴を明らかにすることで，石碑が有する文化的・歴史的価値を議論する契機となることを目的とした。調査の結果，147基の石碑を確認し，その分布は教育学部と工学部でそれぞれ4割に達し，学部の偏りが顕著であること，建立年代に着目すると，東広島キャンパスの移転前の石碑は103基と全体の約7割で，多くが移転前に建立されたことなどが明らかとなった。広島大学は，医学系学部・研究科・施設をのぞくすべての学部などが東広島キャンパスに移転すると同時に石碑も集まることになった。移設により元々建立された地から離れたことで建立当初の意義を失った側面もあるが，多数の石碑が一つのキャンパスに移設されたことで散逸を防ぎ，前身校から新制広島大学，そして統合移転から現在までの歴史を繋ぐ貴重な資料となり得ることが示唆された

Analysis for the units of regional geography on UK’s geography textbook: The case study of “Geog 4th edition”

In Britain, the volume of “Regional Geography” was decreased in “the National Curriculum”. The aim of this paper is to cralify the contents of “Regional Geography” in Britain. We analyzed the geographical school textbook “Geog 4th edition” by Oxfor University Press. We find that “Geog” has only 2 or 3 case studies in each grade. The students don’t learn all of the world in geographical class. That is because it is important to learn the geographical skill

Separated Transcriptomes of Male Gametophyte and Tapetum in Rice: Validity of a Laser Microdissection (LM) Microarray

In flowering plants, the male gametophyte, the pollen, develops in the anther. Complex patterns of gene expression in both the gametophytic and sporophytic tissues of the anther regulate this process. The gene expression profiles of the microspore/pollen and the sporophytic tapetum are of particular interest. In this study, a microarray technique combined with laser microdissection (44K LM-microarray) was developed and used to characterize separately the transcriptomes of the microspore/pollen and tapetum in rice. Expression profiles of 11 known tapetum specific-genes were consistent with previous reports. Based on their spatial and temporal expression patterns, 140 genes which had been previously defined as anther specific were further classified as male gametophyte specific (71 genes, 51%), tapetum-specific (seven genes, 5%) or expressed in both male gametophyte and tapetum (62 genes, 44%). These results indicate that the 44K LM-microarray is a reliable tool to analyze the gene expression profiles of two important cell types in the anther, the microspore/pollen and tapetum
