In this paper, we propose an algorithm for ALCH(D) concept learning from RDF data using minimal model reasoning. This algorithm generates concept expressions in the Description Logic ALCH(D) by giving background knowledge and positive and negative examples in the RDF form. Our method can be widely applied to RDF data on the Web, as background knowledge. An advantage of the method for RDF data is that reasoning on RDF graphs is tractable compared to logical reasoning for OWL data. We solve the problem that RDF data cannot be directly applied to the concept learning due to its less expressive power, speci.cally, the lack of negative expressions. In order to construct expressive ALCH(D) concepts from less expressive RDF data in the concept learning, we introduce (nonmonotonic) inference rules based on minimal model reasoning which derive implicit subclass and subproperty relations from the background knowledge in the RDF form. We prove the soundness, completeness and decidability of the nonmonotonic RDF reasoning in the minimal Herbrand models for RDF graphs. The process of concept learning is divided in two parts: (i) concept generation and (ii) concept evaluation. In the concept generation, minimal model reasoning enables us to derive complex concepts consisting of negation, conjunction, disjunction and quanti.ers and to exclude inconsistent concepts. In the concept evaluation, we evaluate hypothesis concepts with class and property hierarchies where minimal model reasoning is used for expressing more speci.c concepts as the answer for learning. We implement a system that learns some ALCH(D) concepts describing the features of given examples.

Anticoagulant and antiplatelet medications are commonly used for the treatment and prevention of cardiovascular diseases. We studied 84 patients who received heparin as a bridging anticoagulant and antiplatelet therapy during the perioperative period. Hospitalization was extended for adjusting anticoagulant and antiplatelet drugs and also bleeding complications in the perioperative period. There were 25 instances of bleeding complications (29.7%) in this study. These complications mainly occurred when anticoagulant and antiplatelet medications were restarted in the postoperative period. In transurethral surgery, patients taking warfarin and antiplatelet drugs (aspirin or ticlopidine) had a statistically significant increase in bleeding complications compared to patients taking warfarin alone. We compared 51 cases of transurethral resection of bladder tumor, transurethral resection of the prostate holium laser enucleation of the prostate, nephroureterectomy and percutaneous nephrolithotomy with heparinization were compared to 692 cases with no heparinization. The heparinization group had a statistically significant longer hospitalization period and an increase in bleeding complications. There was one instance of thromboembolism (1.2%) in our series. This involved stent thrombosis of a patient who had drug-eluting stent in the left anterior descending coronary artery. She died three days postoperatively. The number of patients taking anticoagulant and/or antiplatelet drugs is predicted to increase in the future due to aging of the population. Guidelines for the management of anticoagulant and antiplatelet therapy in the urological period are considered necessary.

多元的リアリティ論は、A. Schutz以来社会学における重要な一課題となっている。だが、これまでの多元的リアリティ論においては、各リアリティ間の構造的連関や動態が論じられることは比較的少なかったように思われる。本稿では、リアリティの多元性を生むと思われる要因を三つ挙げ、その内の一つの意識状態の多様性に基く多元的リアリティの動態論を導く事を課題とする。三要因を分節したのは、これまでの多くの議論ではリアリティの多元性に関する異なった観点を同時に取り挙げてモデル構成していたので、各リアリティを系統的に抽出し得なかったのではないかと考えるからである。そして、この各リアリティを構成する為に、人間の精神発達過程 (特にピアジェとエリクソンの発達心理学) に着眼し、その発達段階から各リアリティを導く事を試みる。このようにして構成された各リアリティ間には、二つの軸による構造的連関が指摘できる。この連関に基き、動態的な多元的リアリティの一モデルを提出したい。

Represented by story grammar, the conventional analysis with a cognitive science approach regarded narratives as a process in which the character solved problems. This idea was invoked by folklore narratives and is insufficient for a display of narrative structures. With the idea that three conditions compose narratives in general—that are, 1) actual temporality, 2) flow of time, and 3) detachment from the narrator, this paper aimed to show that narratives are comprised of four layers: speech, foreground and background, and comment. As for the background, there are two types that exist: the microscopic type which magnifies the process part of motion, and the macroscopic type which compresses multiple events and presents them as a whole. Furthermore, to explain that these four layers are in figure and ground relationships with each other, and reflect these layers linearly onto discourse, recognition of presence of specific border expressions for each borderline is described.

本研究の焦点はケアとコミュニティである。介護者を中核として組織されるボランタリーなアソシエーション(会や集い等)が、ケア包摂型ともいうべき新たなコミュニティ開発の動力装置として機能するかという極めて実践的なテーマを設定した。近年増加が著しい男性介護者の会や集いにそのフィールドを求めた。活動への参与観察、主宰者へのインタビューや交流等を通して、介護者の会や集いは「ひとりじゃない」という確かな実感に溢れ、同じような立場の人との交流は、介護生活で失いつつあった社会との接点や連帯を修復する「場」となっていることが確認された。
