PURPOSE To determine the conversion coefficients (CCs) from the dose-area product (DAP) value to effective dose in cone-beam CT. MATERIALS AND METHODS A CBCT scanner with four fields of view (FOV) was used. Using two exposure settings of the adult standard and low dose exposure, DAP values were measured with a DAP meter in C mode (200mm×179 mm), P mode(More)
A middleware in ubiquitous computing environment (UbiComp) is required to support seamless on-demand services over diverse resource situations in order to meet various user requirements [1]. Since UbiComp applications need situation-aware middleware services in this environment. In this paper, we propose a semantic middleware architecture to support dynamic(More)
OBJECTIVE This study was designed to investigate the relationship between physical factors and the subjective quality of cone beam computed tomography (CBCT) images used for different diagnostic tasks. STUDY DESIGN CBCT images of a real skull phantom and a SedentexCT IQ phantom were acquired under different exposure conditions (one Dinnova3 CBCT scanner,(More)
BACKGROUND/OBJECTIVES The purpose of this study is to analyze daily kimchi, vegetable and fruit consumption by general characteristics and vegetable and fruit consumption from 1998 to 2012 by the Korean population based on the data of the KNHANES (Korea National Health and Nutrition Examination Survey). SUBJECTS/METHODS This study is based on the(More)
PURPOSE This study was performed to investigate the effect of image enhancement of periapical radiographs according to the diagnostic task. MATERIALS AND METHODS Eighty digital intraoral radiographs were obtained from patients and classified into four groups according to the diagnostic tasks of dental caries, periodontal diseases, periapical lesions, and(More)
BACKGROUND/OBJECTIVES The aim of this study was to examine differences in nutrient intake and food consumption by the presence of metabolic syndrome in Korean adults. SUBJECTS/METHODS Study subjects in this cross-sectional study were recruited from four outpatient clinics in and near the Seoul metropolitan area of South Korea between 2006 and 2012. A(More)
PURPOSE Hand-held dental x-ray system is a self contained x-ray machine designed to perform intraoral radiography with one or two hands. The issue about its usage as general dental radiography is still in dispute. The aim of the present study was to assess the relationship between the amount of battery charge and the tube voltage in different hand-held(More)
A middleware in ubiquitous computing environment (UbiComp) is required to support seamless on-demand services over diverse resource situations in order to meet various user requirements [11].

The amount of data on the Web has recently increased, accompanied by a paradigm shift from the publishing of isolated data to the publishing of interlinked data. Linked Open Data (LOD) provides structured access and enables the easy extension of knowledge, thus allowing data from different knowledge sources to be connected. However, the vocabularies used in(More)
