近年増加したコンテンツ投稿型SNSでは日々膨大にコンテンツが増え続けるため,嗜好には合っているもののユーザが見逃してしまうようなコンテンツは少なくない.また,多くの推薦技術では精度を重視するあまり,その推薦結果に面白みがないという課題がある.本論文では,主に音楽,イラスト,詩等の創作者向けであるコンテンツ投稿型SNSにおける未知性,意外性を考慮した推薦手法について述べる.未知性に関しては,質の高いコンテンツを投稿する投稿者(有力投稿者)に注目し,コンテンツの質を確保しつつもロングテールのテール部分に属する,ユーザがまだ知らないコンテンツを推薦する.意外性に関しては,多くのコンテンツ投稿型SNSで利用されているFolksonomyを利用する.以上の二つの推薦部からなる推薦エージェントを提案し,イラスト投稿型SNSであるPixivの実データを用い,未知性,意外性に関する評価実験を実施した.その結果,推薦リストの6割に未知性,意外性のあるコンテンツが含まれ,本研究の有効性が確かめられた.

マクロ会計は,1940年から41年にかけてイギリスのケンブリッジ学派によって形成されたことを明らかにした。本稿は,これを会計学におけるケインズ革命と呼んでいる。同学派は,ケインズに始まりストーンに継承されて,マクロ会計の国際基準化に大きな貢献を果たした。ケンブリッジ学派については,ティリー(Tily, 2009)によるマクロ会計発展3 段階説と,アメリカ・ケインジアンであるパティンキン(Patinkin, 1976)の統計革命先行説を取り上げる。他方,フリッシュからオークルストに継承されたオスロ学派については,Aukrust(1994)のスカンジナビアにおけるマクロ会計発展5 段階説に依拠しながら,マクロ会計の公理化という独自の理論を生みだしたことを強調した。最後に,現代会計学は,両学派からミクロ会計とマクロ会計の同型性論という視点を継承し,さまざまな会計イノベーションを起こしつつあることを指摘した。

This paper presents a descriptive analysis of Japanese teen slang mazi-manzi "マジ卍" or manzi "卍" in comparison with yabai "やばい." One of their significant characteristics is that they can describe either positive or negative situations: Tesuto goukaku, mazi-manzi! "I passed the exam, woo-hoo!" (positive) or Ame-ni nure-ta, mazi-manzi. "I got wet in the rain, shoot." (negative), and Kono wan-piisu yabai-yo-ne! "This dress is super cute!" (positive) or Kaoiro yabai-yo." You look so pale."( negative).While yabai has often been discussed in terms of syntax, phonology, semantics, andpragmatics in previous studies (Takeuchi(2007), Horasawa and Iwata (2009), Sano (2012), Konno( 2015) etc.), mazi-manzi has not because of its specificity and temporality.The interpretational similarity given above might lead us to consider that they share the same or similar linguistic features. A closer look at these two, however, reveals that they are to be distinguished. In particular, I would like to claim that (i) while yabai shows adjective-like behavior, mazi-manzi displays adjectival noun-like behavior, (ii) while yabai has adverbial use, mazi-manzi does not, and (iii) mazi-manzi imposes more burden of inference in the discourse than yabai.

近年,わが国ではプロのデザイナーによって鉄道車両が設計され,旅行の付加価値を向上させる事例がみられるが,全国的な展開には至っていない.その理由のひとつに,車両デザインと需要増との関係性が明らかではないため,事業者が鉄道車両のデザイン化に消極的であることがあげられる.本論文では,小田急ロマンスカーを対象とし,鉄道車両の車内デザインを考慮した需要予測モデルの構築を目指す.そのために,1)車内色彩デザインの計測手法,2)色彩快適度関数の構築,3)車内デザインの評価手法,4)需要予測モデルの構築,以上4点を検討する.本論文で構築したモデルを用いた分析の結果,車両をデザインすることで,他交通機関からの利用者の転換が望め,一定の収入増加が見込めることを確認した.

A sedimentological study was made of the Flysch-type alternations of Otadai formation, Kazusa group deposited in the central part of the Boso peninsula in upper Pliocene epoch (Fig. 2). The formation consists of rhythmic alternation of sandstone and mudstone and the relative amounts of the two rocks vary in places. Each layer is correlated for more than 30 km in extent, as it has their own characteristics in thickness, texture, composition and colour and is arranged in similar manner at the neighbouring sections (Fig. 3, 4). Several key beds of tuff are the most important in the correlation because of their distinct features. The shape, textural distribution and grain size variation in the layers has been definitely shown by the method stated above. The thicker each layer of sandstone is, the more spacial extent it acquires in general. The layer over 10 cm in thickness at the thickest part reaches more than 30 km in extent. It is asymmetrical in shape owing to the more rapid decrease toward west (Fig. 6). On the other hand, the thickness of mudstone layers increases gradually toward west within the studied area but seems to decrease very rapidly westward (Fig. 5). It is concluded that the thickness variation of sandstone and mudstone assembly is determined by sandstone, that is, the layers of sandstone are very sensitive to the subsidence of the basin. Of course, the subsidence is the neccessary condition for the formation of layers. A layer consists of lamina which are units of mass movement of grains, as will be seen from the Photo. 1. A relatively thick sandstone layer is divided into three intervals based on the nature of lamina, namely, massive graded, parallel-laminated and cross-laminated intervals from the base respectively. But a thin sandstone layer is devoid of massive graded interval and/or parallel-laminated intervals. The arrangement of these lamina is closely related to the thickness variation of a layer (Fig. 6). The grain size distribution and consituents in a layer are also related to the textural arrangement as well as the shape (Fig. 9). The boundaries of textures are nearly parallel to the isometrical lines of median diameter of grain size and sorting coefficient. Shell fragments are concentrated at the bottom of the graded interval, while pumice and plant fragments are often seen in the parallel and cross-laminated intervals. The grain size variation in the mudstone layer seems to be more monotonous and the mean size and sand grain content gradually decrease toward west. As will be known from the fact stated above, sandstone layers are very different from mudstone layers in many respects. And it is observed that the sandstone layer is formed by different way from the mudstone. The inference is substanciated by the difference of faunal assemblages found in both layers. The sandstone has the shell fragments and worn-out foraminifers which are found in the upper neritic zone in the recent environment, while molluscan shells and foraminifers contained in the mudstone are similar to the fauna living in the bottom over 400 m in depth in the Pacific off the Boso peninsula. This fact indicates that sand deposited temporarily under the bottom of shallow sea is transported into the bathyal environment where mud is usually deposited. The direction of current transporting sand grains should be from west to east as is assumed from the sole markings developed under the bottom of sandstone layers and cross laminations (Fig. 10). The nature of flow is inferred from the result of laboratory experiments and observations of alluvial channels. It is controlled by many variables such as depth, slope, size and shape of grains, viscosity and density of sediment-water mixture, etc. So the concept of flow regime (SIMONS & RICHARDSON, 1961) is very useful as it allows grouping of the combined effects of those factors. The classification of flow regime is based on form of the bed configuration, mode of sediment transport, process of energy dissipation and phase relation between the bed and water surface (Fig. 11). According to these elements, it is divided into lower and upper flow regimes (Fig. 11). In the lower flow regime, lamina which are horizontal or inclined 10 degrees or less down stream are well developed, while lamina is not distinct in the upper regime since amount of sediment transported by the flow increases and is not sorted. These changes of lamina might correspond to the textural arragement in a sandstone layer, from the base upward, massive graded, papallel laminated and cross-laminated intervals. It shows that a sandstone layer is formed by a flow which diminishes its energy gradually. Sand mass deposited in the shallow sea collapses just like a landslide and then slides down the slope which is maintained by the subsidence of the basin. It fills the subsiding areas and the relatively flat slope is formed and then mud particles fall down uniformly on it. During the deposition of mud, subsidence of the ground is continued and the depositional areas for sandstone are prepared.

現在,組織の知識を蓄積するために多くの組織では共有フォルダを用いてボトムアップ的に情報を大量に蓄積している.しかしながら,多くの情報は情報管理の属人化がおこり,組織環境の変化によりどこにどのような情報があるのかが分からなくなった結果,情報が死蔵され,組織知識の忘失がおこる.そこで,長くにわたって情報を継承してきた事例を基に,死蔵することなく組織の知識を継承する手法を検討した.その結果,長期にわたって情報を蓄積するためには,時間(年度),知識分類,案件の順番で情報を管理することが有効である.また,組織知識として蓄積・継承するべき知識の分類には7つの項目があるが,そのうち組織の記録が最も重要であることが分かった.Numerous information are stored in the shared folders for storing organizational knowledge by members, day by day. However, the information management depends on the member's memory, then many stored information are hoarded by changing environment of the organization, at last organizational knowledge is lost. In this paper, we examined the shared folder construction method which can avoid dead-stock, based on the case study of sharing and storing information in the organization between the long-term. As the result, we clarified that the shared folder which was constructed by the layer of time (year), knowledge classification, and matter can avoid hoarding. The knowledge classification had seven types, and the record of organization was the most important classification in those.
