In this paper, we describe a new bitmap indexing based technique to cluster XML documents. XML is a new standard for exchanging and representing information on the Internet. Documents can be hierarchically represented by XML-elements. XML documents are represented and indexed using a bitmap indexing technique. We define the similarity and popularity(More)
BACKGROUND In the present study, we aimed to compare clinical and radiographic outcomes between hook plate fixation and coracoclavicular (CC) ligament reconstruction for the treatment of acute unstable acromioclavicular (AC) joint dislocation. METHODS Forty-two patients who underwent surgery for an unstable acute dislocation of the AC joint were included.(More)
BACKGROUND The healing failure rate is high for partial-thickness or small full-thickness rotator cuff tears. PURPOSE To retrospectively evaluate and compare outcomes after arthroscopic repair of high-grade partial-thickness and small full-thickness rotator cuff tears and factors affecting rotator cuff healing. STUDY DESIGN Cohort study; Level of(More)
HYPOTHESIS Expectations and concerns affect the patient's postoperative improvement after rotator cuff surgery and are associated with preoperative functional status and sociodemographic factors of the patients. METHODS We studied 128 patients who underwent rotator cuff surgery. Questionnaires regarding preoperative expectations and concerns were(More)
This paper addresses the problem of semantic query reformulation in the context of object-oriented deductive databases. It extends the declarative object-oriented speciications of F-logic proposed by Kifer and Lausen using the semantic query optimization technique developed by Chakravarthy, Grant, and Minker. In general, query processing in object-oriented(More)
PURPOSE The purpose of this study was to analyze factors affecting the treatment outcomes and prognoses of arthroscopic debridement for refractory lateral epicondylitis. METHODS We included 45 patients who had undergone arthroscopic extensor carpi radialis brevis release for chronic refractory lateral epicondylitis between October 2008 and December 2012.(More)
| Although knowledge discovery is increasingly important in databases, discovered knowledge is not always useful to users. It is mainly because the discovered knowledge does not t user's interests, or it may be redundant or inconsistent with a priori knowledge. Knowledge discovery in databases depends critically on how well a database is characterized and(More)
The Earth Observing System (EOS) Data and Information System (EOSDIS) is perhaps one of the most important examples of large-scale, geographically distributed, and data intensive systems. This paper presents various facets of a data and information architecture for EOSDIS. EOS data is organized by means of an object-oriented schema, while EOS knowledge is(More)
BACKGROUND Arthroscopic rotator cuff repair generally has a good clinical outcome but shoulder stiffness after surgery due to subacromial adhesion is one of the most common and clinically important complications. Sodium hyaluronate (HA) has been reported to be an anti-adhesive agent in a range of surgical procedures. However, there are few reports of the(More)
