A heavy rain event in July 2018 caused many natural disasters such as landslides and floods in western Japan. Many shallow landslides were induced by heavy rain between the night of July 6 and the morning of July 7 in Gogoshima Island, which is located offshore of Matsuyama City, Ehime Prefecture. The main industry of the island is the cultivation of oranges. However, the orange farming infrastructure was devastated by shallow landslides across a large portion of the island. We created a spatial distribution map of the shallow landslides, based on interpretation of the SPOT-7 satellite imagery, to understand their characteristics. Moreover, the mass movement processes were clarified using the results of geomorphological and geological field surveys. The analysis revealed the following : 1) The shallow landslides induced by the heavy rain event were distributed across the island, and the total number of landslides was 207. 2) Relatively elongate, shallow landslides are distributed on the slopes of Mt. Kofuji. The shallow landslide materials changed to debris flows. 3) The field survey revealed that the heads of shallow landslides are located on the geological boundary between granodiorite and andesite. The landslide material was formed of loose, highly weathered granodiorite, called “masa” in Japanese, and thermally metamorphosed granodiorite. 4) The previous debris flow deposits that filled the gullies were eroded by the new debris flows and flash floods.

Turbidites are developed in the Permian-Triassic Sambosan and the Jurassic-Cretaceous Shimanto group in Japan. The Turbidite sequences are well distributed in the Tamagawa district, the Kanto mountainous land, and in the Oigawa district (Fig. 1). The sequence in the latter district occupies the southern wing of a grand recumbent fold. Here, turbidite-poor shale, turbidite (the A formation), non-turbidite with turbidite (the B), turbidite (the C) and turbidite-poor shale formations are distributed. Average thickness and standard deviation of the sandstone and shale beds within each 5m column of strata were measured (Tables 1-3). Average thickness of sandstone beds varies with the horizon, especially with the major cyclic sedimentation. On the other hand the average thickness of shale beds is fairly constant in the turbidite sequences (the A and C formations). Thickness of the sandstone beds in the turbidite sequences shows log-normal distributions (Figs. 16, 17). However, that of the shale in the turbidite sequences shows distributions similar to the normal ones. The distributions are probably due to the fact that the shale deposition is proportional to time and that the time interval of turbidity currents is fair constant. This is confirmed by a fact that the number of turbidites during the deposition of a unit shale is fairly constant (Table 4). The standard deviation of thickness distribution is related to the thickest bed within each 5m column, especially for the sandstone beds. Thickness distributions of sandstone and shale beds in the turbidite-poor and the turbidite-rich sequences (the B formation) are quite different from those of the turbidite sequence (the A and the C formation) in the Oigawa (Fig. 18, Table 2) and show much wider distribution. The thickness of sandstone beds is not related to that of the overlying and the underlying shale beds in the A and C formation (Figs. 22, 23). However, turbidite beds in the turbidite-poor shale formation underlying the A formation are composed of a very thin sandstone part and rather thick silt part. In this case thickness of the overlying silt and shale appears to be related to that of the underlying sandstone part. The thickness of turbidite sandstone beds is also related to the clasticity (Fig. 24) and sedimentary structures. Sole marking is not common on the underside of the thinner beds (70cm or less). Laminated structures, convolute structures and other are common in the thinner beds (10cm or less), but not common in the thicker beds. In the turbidite together with the non-turbidite sequences there are cyclic sedimentations. Sandstone-shale diagrams (Figs. 6, 10, 11, 14, 15), total thickness (Figs. 4, 7, 13), average thickness and the thickest bed (Fig. 26) within 5m column, and accumulation of sandstone during the deposition of a unit thick shale (Figs. 8, 10, 15) show the cyclic sedimentations which are classified into major and minor ones. The major cyclic sedimentation is most well shown by the distribution of thickest bed within each 5m column (Fig. 26). The bed usually corresponds to the thickest bed within each minor cycle (Fig. 19). The major cycle may be related to transgression and regression and is not related to the chert deposition at Unazawa (Fig. 7). Minor cyclic sedimentations are further classified into "increasing" and "decreasing" types (Fig. 12). The "increasing" type appears to be generally formed during the regression, the "decreasing" type during the transgression. The minor cyclic sedimentations are well shown by the sandstone-shale diagrams as well as by the thickness distribution of sandstone beds according to the sedimentation order (Figs. 12, 20). There was a basin of the normal sedimentation with some steep cliffs at the regressional stage (Fig. 27), a part of this basin becoming the drainage of turbidity currents when the sea level was rather high. At the stage of transgression, shale deposited principally with muddy turbidites. The major cyclic sedimentation may have been formed under such a circumstance. The frequency of great earthquakes and the tectonic position in the westernmost Pacific near Japan are comparable with those of turbidite sequences in the Oigawa district, the turbidites having been probably produced by such earthquakes.二畳紀-三畳紀の三宝山層群,ジュラ紀-白亜紀の四万十層群にはTurbidites層が発達している.このTurbidite層は多摩川地域・南部大井川地域によく見られる(Fig. 1).大井川地域のこの層群は大きな横臥せしゅう曲の南翼をなしており, Turbiditeの少ない頁岩層, Turbidite層(A層), Turbiditeを伴うnon-Turbidite層(B層), Turbidite層(C層), Turbiditeの少ない頁岩層からなつている. 5mの厚さの地層の中の砂岩層の平均層厚(Table 1-3)は層準に応じて,特に堆積の大りんねに応じて変化する.一方頁岩層の平均屈厚はA, C層内では層準にかかわらずほぼ一定である.

古典的な経済学では,通常,投資家は完全合理的な行動を行うと仮定する.そのような仮定をおいた理論では,市場均衡の存在を証明することが可能であるが,現実の投資家にとって重要な,スプレッド(アスクとビッドの差)やマーケットインパクト(注文に対して価格がどのぐらい変動するか)を説明することは難しい.その一方で,近年,投資家の合理性をまったく仮定せず,注文はポアソン到着に従って到着すると仮定する「ゼロインテリジェンスモデル」が提案されている(Smith et al. 2003).このモデルでは,スプレッドや価格の拡散係数を定量的に説明することが可能である(Farmer et al. 2005).しかしながら,ゼロインテリジェンスモデルでは,マーケットインパクトを表現する量の一種である,Kyleのλ(単位株数の注文に対して平均してどのぐらい価格が変動するか)を説明することはできなかった.本研究では,まず,東京証券取引所の実データを用いて,指値注文分布や直前の注文に依存して注文到着率がどのように変動するかなどの性質を調べた.次に,ゼロインテリジェンスモデルにそれらの性質を導入し,シミュレーションを行った.このモデルを「ローインテリジェンスモデル」と呼ぶことにする.その結果,ローインテリジェンスモデルでは,スプレッドや拡散係数に加えて,Kyleのλをも説明できることが分かった.このことは,金融市場の流動性を理解するには,注文と注文分布の相互作用,あるいは注文同士の相互作用が重要である可能性を示唆する.

本研究の目的は,出生時期に低体重であった者(Low birth weight infant:LBWI)と正常体重であった者(normal birth weight infant:NBWI)が成人期を迎えた際の骨量ならびに骨の発育に与える因子に違いが認められるかを確認し,将来の骨関節疾患発症リスクについて検討することである。対象は,本邦でLBWI 急増時期に生まれ,現在成人期にある女子大生を母集団とし,LBWI 群(6名)とNBWI 群(6名)を抽出した。骨量面積率や骨塩量,下腿身長比や体重などの計測とともに,学齢期と思春期の運動時間を聴取し,両群間で比較した。その結果,両群間で骨量面積率などに有意差は認められなかったが,下腿身長比はLBWI 群が有意に低値を示した(p<0.05)。従って,出生時体重の違いは成人期の骨密度には影響を及ぼさないが,LBWI は下腿身長比の短縮という形で骨の発育不全を引き起こす可能性が示唆された。今後,この骨発育不全が引き起こされるメカニズムの解明とともに,LBWI が老年期の骨に与える影響についても追跡調査する必要性があることが示唆された。

Molluscan fossils in storm-generated shell beds are commonly transported and damaged. Here we report a case study on assessing mollusc shell transport from original habitats to lower shoreface storm deposits. Fossil assemblages recovered from eight storm-generated shell beds in the Pliocene Dainichi Formation, Kakegawa Group, Japan, were examined. We assessed temporal changes in the relative frequency of three ecological categories (mode of life of bivalves, substrate preference, and habitat depth), using available information on modern molluscan species. The studied stratigraphic section was subdivided into two distinct units based on taxonomic compositions and the ecological categories. The lower unit (D-1, D-2, D-2') is characterized by rocky-bottom dwellers such as Area arabica, Cardita leana, Chama sp., Lima vulgaris, Collisella spp., and Siliquaria cumingii. The gravelbottom dweller Arcopsis symmetrica is more common in the lower unit. The upper unit (D-3 to D-7) can be distinguished from the lower one by a decrease in deposit feeders that are better able to escape sudden burial than suspension feeders. In this unit, suspension feeders that generally inhabit quiescent environments increase in the place of the deposit feeders. The results indicate the followings: (1) the storm-generated shell beds in the study section represent indigenous fossil assemblages; (2) thin and flat bivalves (e.g., "Macoma" spp. and Saccella spp.) exclusively deposited on the laminar surface (D-2') were more or less transported, whereas gastropods accumulated in lag deposits (D-2) of hummocky cross-stratified beds were residues after a storm event and its attendant winnowing of fine sediments; (3) paleontological evidence obtained from the lower unit indicates the existence of a rocky coast during the time when the Dainichi Formation began to deposit in the study area (Dainichi, Fukuroi City); and (4) the changes in the ecological categories from the lower to the upper unit are compatible with the upward-deepening sedimentary sequence recorded in the Dainichi Formation.

This article surveys the concept of framing in political consciousness research, and examines its logical implications and theoretical validity as a leading principle of researches. The psychological principles which determine the perception of decision-making problems and the evaluation of probable results which come out of the decisions will bring about remarkable shifts of preference when the same issues are framed in different manners. And this new shift will be easily anticipated and predicted so far as a paradigm change of framing is concerned. In consequence of the consideration, a new framework will be presented as a guiding principle of researches.

The dose of direct oral anticoagulants (DOACs) must be determined based on package insert recommendations. There are reports on the rate of inappropriate DOAC dose usage defined as a dose deviating from the approved dose in the package insert but no reports on factors that led to such deviations. Thus, patients who were admitted to the Suzuka Kaisei Hospital between 1 April 2016 and 31 March 2017 were chosen as subjects. Moreover, the factors that during hospitalization led to dose deviation from the package-insert DOAC dose were retrospectively examined. The characteristics of patients administered doses deviating from the package insert were compared with those of patients in the appropriate-dose group. The finding was that the proportion concomitantly administered antiplatelet agents was higher in the underdose group. In contrast, deviations from the recommended dose did not occur when DOACs were combined with CYP3A4 inhibitors or P-glycoprotein (P-gp) inhibitors. It was suggested that increase in the risk of hemorrhage by antiplatelet agents in combination with oral anticoagulants could explain deviations from the stipulated DOAC dose. In addition, a higher proportion of patients in the overdose group showed depressed Ccr, and gastrointestinal bleeding. In future, it will be necessary to propose principle-based dose changes for patients administered doses deviating from the package insert. If an underdose is administered, it is important to make a dose change that takes the concomitant drugs into consideration.
