OBJECTIVE Determine the feasibility and outcome of a pilot program to increase farm workers' use of hearing protection when performing activities with high noise exposure. DESIGN The study was a quasi-experimental study. SAMPLE Eight intervention farmers and 17 comparison farmers participated in the study. MEASURES Before and after the intervention,(More)
Many algorithms for scheduling DAGs on multiprocessors have been proposed, but there has been little work done to determine their eeectiveness. Since multi-processor scheduling is an NP-hard problem, no exact tractible algorithm exists, and no baseline is available from which to compare the resulting schedules. Furthermore, performance guarantees have been(More)
BACKGROUND There have been nearly 70 different histologic subtypes of basal cell carcinoma (BCC) described. Some of the subtypes have been shown to have clinical relevance. The degree to which one type may merge to another, within the same tumor mass, has been poorly studied. OBJECTIVE To determine if BCCs maintain biopsy histology throughout the entire(More)
BACKGROUND The basosquamous cell carcinoma (BSCC) is a poorly defined and often misunderstood cutaneous malignancy. OBJECTIVE The purpose of this study was to compare, using immunohistochemical techniques, the BSCC, basal cell carcinoma (BCC), and squamous cell carcinoma (SCC). METHODS BSCC occurring at Pennsylvania State University over the past 10(More)
INTRODUCTION High-fidelity medical simulation of sudden cardiac arrest (SCA) presents an opportunity for systematic probing of in-hospital resuscitation systems. Investigators developed and implemented the SimCode program to evaluate simulation's ability to generate meaningful data for system safety analysis and determine concordance of observed results(More)
INTRODUCTION Emergency department procedural sedation (EDPS) is becoming widespread. Simulation may enhance patient safety through evidence-based training, effective assessment, and research of EDPS operators in pertinent knowledge, skills, processes, and teamwork. METHODS Investigators developed a 2-scenario in situ simulation-based methodology and(More)
Dual-task procedures-elaborative strategy use and finger-tapping-were used to examine both recall and mental effort demands of elaboration strategy use with equal numbers of boys and girls at grades two and three. Knowledge-base access was examined by comparing different item types in the associative learning list: masculine, feminine, and mixed. Results(More)
A 49-year-old man electively chose to undergo a trial of intravenous chemotherapy with 5-fluorouracil (5-FU) for his inherited punctate palmoplantar keratoderma (PPK). His father also had this skin disorder, which coincidentally cleared after 2 courses of chemotherapy consisting of 5-FU and cisplatin to treat his lung cancer, prompting the patient to(More)
The goal of the development phase of the CPR Instructor Real-time Review through Use of Simulation (CIRRUS) research program was to create a video library portraying a spectrum of objectively verified simulation chest compression performances. Investigators scripted and recorded 12 two-person cardiopulmonary resuscitation (CPR) videos with specific chest(More)
