Abstract  スーパーサイエンスハイスクール(SSH)指定校や理数科で実施する課題研究を充実させるために,自然科学研究の構成方法を実践的に学ぶことのできる授業を開発し試行実践した。自然科学分野での研究者養成で日常的に行われているOn the Job Training (OJT) を模した授業展開を構成し,実験・観察や研究をデザインするときに必要な要点を伝えることを目指した。素材として蒸発潜熱を測定する実験を用い,SSH 指定校である岡山県立倉敷天城高等学校の理数科1年生39名を対象に7時間の授業実践を行った結果,科学的な仮説の設定方法や思考と発想のポイントを含めた研究の進め方の理解が進んだという結果が得られている。一方で,班内で積極的に議論しながら実験を進める姿勢には大きな向上は認められなかった。議論の場面を強制的に設定するだけでなく,議論を促す仕掛けが必要とされる。

Abstract Pairing–based cryptosystems are well implemented with Ate–type pairing over Barreto–Naehrig (BN) curve. Then, for instance, their securities depend on the difficulty of Discrete Logarithm Problem (DLP) on the so–denoted G3 over BN curve. This paper, in order to faster solve the DLP, first proposes to utilize Gauss period Normal Basis (GNB) for Pollard’s rho method, and then considers to accelerate the solving by an adoption of lazy random walk, namely tag tracing technique proposed by Cheon et al.

Abstract Recent efficient pairings such as Ate pairing use two efficient rational point subgroups such that π(P) = P and π(Q) = [p]Q, where π, p, P, and Q are the Frobenius map for rational point, the characteristic of definition field, and torsion points for pairing, respectively. This relation accelerates not only pairing but also pairing–related operations such as scalar multiplications. It holds in the case that the embedding degree k divides r − 1, where r is the order of torsion rational points. Thus, such a case has been well studied. Alternatively, this paper focuses on the case that the degree divides r + 1 but does not divide r − 1. Then, this paper shows a multiplicative representation for r–torsion points based on the fact that the characteristic polynomial f(π) becomes irreducible over Fr for which π also plays a role of variable.

Title Alternative The oldest fossil forest in Japan discovered from the Upper Triassic Nariwa Group, Okayama Prefecture, SW Japan -Implication for reconstruction of depositional environment and paleovegetation-

Abstract Erect fossil stumps were found from the outcrop of the Upper Triassic Hinabata Formation, the uppermost part of the Nariwa Group at Hinabata, Nariwa-cho,Takahashi City, Okayama Prefecture, SW Japan. They are evidence of the oldest fossil forest in Japan. The Upper Triassic Nariwa Group is mostly composed of non-marine deposits except the marine Jito Formation and characterized by the abundance in plant fossils. The marine Jito Formation is characterized by occurrence of Norian Monotis ochotica. On the basis of detailed observation of the occurrence of erect fossil stumps, as well as sedimentary facies of fossil-bearing unit, the fossil forest was interpreted to have grown on the top of the natural-levee units. One of the erect fossil stumps was identified as Xenoxylon sp.

Title Alternative The temperature and pressure conditions of synthetic Sibirskite and Parasibirskite
FullText URL esr_019_1_013_017.pdf
Author Kano, Masahiro| Yamakawa, Junji|
Abstract Sibirskite (CaHBO ) and parasibirskite ₃ are in the relation of polymorphism, these are regarded as the alteration products of takedaite (Ca₃B₂O₆), occurs at Fuka mine, Okayama Prefecture. The synthesis of parasibirskite was reported by the Schäfer (1968a, b) etc. and the synthesis of sibirskite was reported by the Sun et al. (2011). To determine the formation condition of sibirskite and parasibirskite in the natural, they were synthesized from the natural takedaite (Ca₃B₂O₆). As a result, both of sibirskite and parasibirskite were formed by the duration time of 7 days with 1000 kg/cm2 and 300 oC, on the other hand, only sibirskite was formed by the duration time of 14 days with the same condition. In addition, the mixtures of sibirskite and parasibirskite were examined under the various temperatures and pressures of hydrothermal conditions. As a result, the upper limit of the stable temperature and pressure conditions of sibirskite was estimated between 350 oC and 400 oC at 1500 kg/cm2, and between 400 oC and 450 oC at 500 kg/cm2 . In the higher temperature than the condition, sibirskite were changed into shimazakiite (Ca₂B₂O₅).

Title Alternative Folded structure of the Carboniferous Ko-yama Limestone Group, Akiyoshi Belt, SW JAPAN
FullText URL esr_019_1_005_011.pdf
Author Inada, Noriyuki| Suzuki, Shigeyuki| Ishida, Keisuke|
Abstract The fold structure of the Akiyoshi Belt was analyzed in Kawakami-cho, Okayama Prefecture, where the Lower Carboniferous to Middle Permian Ko-yama Limestone Group (Yokoyama et al., 1979), Permian Yoshii Group (Sano et al., 1987) and Triassic Nariwa Group (Teraoka, 1959) are distributed. The Nariwa Group unconformably covers the Paleozoic successions (Otoh, 1985). The Lower Carboniferous to Middle Permian Ko-yama Limestone Group, dated by foraminifers and fusulinids (Yokoyama et al., 1979), is mainly composed of massive limestone with basic volcanics, acidic tuff and chert. The Paleozoic successions of the Akiyoshi Belt were folded during the Middle to Late Permian (Suzuki et al., 1990). Strata of the Ko-yama Limestone Group generally strike E-W and dip to the north. The Hoya section about 300 m thick is composed of limestone, basic tuff, chert and acidic tuff, limestone, basic lava and tuff in ascending order. In this section, Ishida et al. (2012) recognized a nearly complete conodont faunal succession ranging from the upper Visean to the lower Moscovian. The faunal succession indicates younging southward, and the strata are overturned. A folded strucuture of tight overfold with north-dipping axial plane was reconstructed. Similar style of small scale overfolds of banded chert and turbidite were observed in the overlying Yoshii Group.

Title Alternative Holocene environmental and sea-level changes of the Okayama Plain – evidence from peat beds –
FullText URL esr_019_1_001_004.pdf
Author Suzuki, Shigeyuki|
Abstract Quaternary peat beds from bore-hole samples deliver information to reconstruct paleoenvironment. Altitudes of dated non-marine peat beds and marine beds allow to be created a sea-level curve. 4 peat beds (A to D) are identified from the uppermost Pleistocene to Holocene deposits of the Okayama Plain. They thought to be deposited at stable events during sea-level change.
