Text adaptation is a teacher practice used to help with reading comprehension and English language skills development for English language learners (ELLs) (Carlo, August, McLaughlin, Snow, Dressler, Lippman, Lively, & White, 2004; Echevarria, Vogt and Short, 2004; Yano, Long and Ross, 1994). The practice of text adaptation involves a teacher’s modification(More)
The need for more realistic and richer forms of assessment in educational tests has led to the inclusion (in many tests) of polytomously scored items, multiple items based on a single stimulus (a "testlet"), and the increased use of a generalized mixture of binary and polytomous item formats. In this paper we extend earlier work (Bradlow, Wainer & Wang,(More)
PURPOSE Patterns of prescriptions are markedly influenced by regional disease entities, medical education, culture, economic status, and available pharmaceutical companies. Features of adverse drug reactions (ADRs) may vary in different countries. In this study, we analyzed the causative drugs and clinical manifestations of spontaneously reported ADRs in(More)
Aspirin-intolerant asthma (AIA) is characterized by severe asthmatic attack after ingestion of aspirin and/or non-steroidal anti-inflammatory drugs. In this study, we investigated the relationship between Prostaglandin E2 receptor (PTGER) gene family polymorphisms and AIA in 243 AIA patients and 919 aspirin-tolerant asthma (ATA) controls of Korean ethnicity(More)
BACKGROUND The 16-kDa protein of buckwheat (BW) has been implicated as a major allergen in BW allergy. OBJECTIVE To characterize the 16-kDa allergen and evaluate its clinical significance as an indicator of BW allergy. METHODS Complementary DNA from the 16-kDa allergen was cloned and expressed in Escherichia coli. Allergenicity was confirmed with IgE(More)
BACKGROUND/OBJECTIVES Mitomycin C (MMC) is used in the prevention of upper airway stenosis. However, the efficacy of MMC is still debatable, and the potential complications of MMC use have been scarcely reported. We evaluated the efficacy and early complications of MMC in a wound model of the subglottis. STUDY DESIGN A randomized animal study. METHODS(More)
OBJECTIVES Although difficult laryngeal exposure (DLE) is a common problem encountered during microlaryngosurgery, reliable predictors of DLE and grading systems of laryngeal exposure have been scarcely suggested in the field of laryngology. We propose a new classification of laryngeal exposure focusing on the extent of glottic visualization. METHODS We(More)
OBJECTIVE The prevalence of asthma is increasing, and asthma causes considerable socioeconomic burden worldwide. Few studies have been conducted to evaluate the risk factors associated with economic cost of asthma in Korea. This study evaluated asthma cost according to severity, control, and patient factors in Korean tertiary hospitals. METHODS Direct and(More)

OBJECTIVES It is difficult to develop models of subglottic stenosis in small animals that ensure reliable stenosis. We therefore sought to establish a new animal model of subglottic stenosis in rabbits and observe subglottic wound healing. METHODS Using a diode laser under endoscopic visualization after anterior tracheal incision, we induced(More)
