The visualization of the inner state of a blast furnace was investigated by exploiting the feature of cosmic-ray muon that attenuates according to the density and the thickness of the object through which it penetrates. The distribution of the cosmic-ray muon accumulated in an object in a blast furnace during a certain period has been determined by a probing system provided with two sets of a pair of panels with plastic scintillation counters segmented in parallel along each direction of both sides. First, measurement was performed in the furnace hearth structure that had been taken out after the shutdown of Oita No. 2 Blast Furnace repaired in 2004. Next, another measurement was performed in the same manner in the renewed furnace hearth of Oita No. 2 Blast Furnace which had just started working after its repairs. The density of the material at the iron-rich portion inside the hearth was estimated from the accumulation ratio obtained from the relation between the intensity of the muon channel passing through the iron-rich part in the hearth and that passing through its opposite channel symmetric to the coordinate origin. Then, the level of the furnace bottom brick, meaning its eroded thickness, was estimated from those accumulation ratios in relation to each channel crossing both the iron-rich part and the furnace bottom brick. The possibility of the density distribution of the material inside a blast furnace and the remaining thickness of bricks being estimated by this measurement method was identified.

This paper explores how the original landscape map can be useful in a Japanese high-school class for teaching environmental and social diversity as an opportunity for cross-cultural communication. We conducted a collaborative class at Tajimi High School in Gifu Prefecture, which was attended by several foreign visitors (i.e., from South Africa, Namibia, and France) as an interdisciplinary activity of biology, geography, and English. Using original landscape maps, participants could compare differences in their biological, cultural, and geographical environments and communicate their thoughts in English. In particular, most of the Japanese high-school students, who had rarely talked to foreigners, found the original landscape maps useful for communication. On the other hand, the students’ original landscape maps suggested a correspondence with the typical images of “traditional Japanese landscape,” and also with the topographical environment and landscape structure of the basin in which they lived. Nevertheless, this classroom practice illustrates that comparing original landscape maps encourages the participants to learn the differences in their natural environments and the life experiences of the people in them. Moreover, the original landscape maps help participants to understand environmental changes over time, and thus changes in their lifestyles, as the original landscape maps are suitable for describing one’s memories, thoughts, and personal experiences. They also help the participants’ English communication by providing a visual description of one’s memory, which motivates them to learn more and become efficient in English. Therefore, the authors conclude that original landscape maps can be recommended to promote an interdisciplinary understanding of environmental, geographical, and cultural diversity.

本稿は,北海道平取町を事例に,ヒグマの採食行動の季節性を踏まえ,ヒグマが出没する集落環境とそれを形成する人間活動を分析することで,ヒグマが集落へ出没する人的要因を明らかにした.まず平取町を含む日高地域を対象に,ヒグマの胃内容物データより,人間活動に起因する食物の採食時期を把握した.次に平取町において,ヒグマが出没する地点の土地利用を分析した.さらにヒグマの駆除に携わる狩猟者12名に聞取り調査を行い,周年的な農業,駆除活動の情報を得た.その結果,①春から初夏に,農地周辺,捕獲場所から近い林野,藪地にエゾシカの駆除死体が埋設されたり,回収されずに放置されており,ヒグマがそれらを摂取できること,②酪農・畜産農家が所有するデントコーン畑は,住宅地から離れ,森林に近接して立地するため,晩夏から秋の成熟期に被害が多いことが明らかになった.
