At many hospitals,basic information concerning medicines,such as package insert information,is entered into a database through the prescription-ordering system.However,up till now there has been no hospital where the sharing and evaluation of medical information (such as Q&A reports and prescription inquiry records) is conducted via an in-hospital local area network (LAN).The important points in making a system for this purpose are information sharing on Q&A reports (mainly questions from physicians and nurses) among pharmacists as well as physicians and nurses,making a database of records of prescription inquiries from pharmacists to doctors and ensuring that past records may be rapidly searched.
With this in mind,using FileMaker Pro 8.5 (FileMaker,Inc.),we configured a drug information database that is accessible via the in-hospital LAN and provides medical information such as the above.It was evaluated using a questionnaire survey targeting 20 physicians,23 nurses,and 18 pharmacists.The results showed that 80.0% of the physicians,82.6% of the nurses,and 94.5% of the pharmacists considered the Q&A database to be useful.We therefore conclude that establishing a system such as this is effective in enabling physicians,nurses,and pharmacists to share information not only in the pharmacy but also in wards in real time.

本稿では，ポータルサイト向けの情報検索エンジンを提案する．本検索エンジンは，公設試験研究機関のポータルサイト上に設置され，各公設試のWebサイトに分散する実験設備の情報を一括検索するものである．設備情報は，Webクローラによって各Webサイトから自動収集される．クローラが訪問するURLを限定することで，設備情報以外の情報をできる限り排除する．既存のポータルサイトに見られる横断検索と比較して，本検索エンジンの方が，検索精度の面で優れていることを示す．さらに，本検索エンジンの適用範囲について考察し，約94%の公設試験研究機関に適用可能であることを示す．

This paper describes a new approach for high-performance image searching method named interlaced fast sequential matching and its application to document image processing for OA system. Conventional image retrieval method for a huge image such as Correlation Matching and SSDA have a shortcoming with their performance. Thus, we introduce the interlaced fast sequential matching in order to avoid the difficulty in the conventional methods. Generally speaking, image retrieval in many kind of documents continues to be one of the most common application for document prcessing. Therefore, if we can find an efficient method to retrieve any character objects without OCR process, the more efficient document management can be performed. We first discuss some essential issues to be considered in document processing with large document image. Experimental results by using the proposed method are also described. The good performance of the interlaced fast sequential matching approach is shown.

Companies make use of the voice of the customer in their product development work and their efforts to increase customer satisfaction. To use the voice of the customer more effectively, companies need to be able to classify text content representing the voice of the customer and direct it toward the pertinent department. Various methodologies have been proposed, but classification errors occur because of ambiguity in the meaning or interpretation of text. In the present research, application of parameter design to the classification of the voice of the customer improved the robustness of classification performance with respect to textual variations and reduced the number of man-hours spent on classification by a factor of four. In addition, when the results were tested by the F-measure, which is widely used in text classification, a high S/N ratio was found to be associated with a high F-measure, confirming the usefulness of the S/N ratio in the field of text classification

 診療記録には様々な「境界」が存在している．紙カルテでは科別管理や入院カルテの分冊が一般的であった．電子カルテではサブシステムごとの記録管理が典型である．これらの境界が多いほど目的の記録へのアクセスに手間がかかる．よって診療上は，すべての記録は論理的に1箇所で管理され，統一的な方法で閲覧できること（診療記録の統合管理）が望ましい．
 本研究の目的は，DACS（Document Archiving and Communication System）における診療記録文書の統合管理の有効性を検証することである．そのため，阪大病院で稼働中のDACSのシステムログを分析し，前述の境界を跨ぐ文書閲覧が実際にどの程度発生しているかを調べた．
 分析の結果，137,040個のアクセススレッド（医師による一連の文書閲覧の系列）が特定された．その42.2%が診療科の境界を跨ぐ閲覧，27.7%は入院の境界を跨ぐ閲覧，69.1%はサブシステムの境界を跨ぐ閲覧を含んでいた．これらは診療記録を統合管理することの有効性を示唆していると考えられる．

本研究では，水害ハザードマップの精度検証を奈良県王寺町を対象に行い，その検証結果が対象地域に与える影響を考察した．精度検証では既存の浸水想定区域図に使用された地盤高データを差し替え，新しい浸水想定区域図を作成したのち，比較検討した．結果，全体的には差異が少なく，局所的には細かい浸水想定の差異が見られた箇所がいくつか確認できた．差異が生じた箇所は地盤高の変化が急激になっている場所と対応しており，これが差異の大きな要因であると考えられる．また，差異が小さいにもかかわらず浸水想定のランクが変化している箇所も確認できた．このうち，ランクが下方修正された箇所は重大な水害リスクをはらんでいる可能性が示唆された．
