OBJECTIVE Emergency department (ED) overcrowding is acknowledged as an increasingly important issue worldwide. Hospital managers are increasingly paying attention to ED crowding in order to provide higher quality medical services to patients. One of the crucial elements for a good management strategy is demand forecasting. Our study sought to construct an adequate model and to forecast monthly ...

OBJECTIVES From the introduction of HIV into the Republic of Korea in 1985 through 2012, 9,410 HIV-infected Koreans have been identified. Since 2000, there has been a sharp increase in newly diagnosed HIV-infected Koreans. It is necessary to estimate the changes in HIV infection to plan budgets and to modify HIV/AIDS prevention policy. We constructed autoregressive integrated moving average (AR...

The objective of this study was to investigate the utilization waste tea wood fibers (WTWF) and effect maleic anhydride treated polyethylene (MAPE) in thermoplastic composites. For purpose, HDPE as matrix, WTWF lignocellulosic filler MAPE coupling agent were used. Six different composites produced by injection molding method; 0-15-30% ratio, with without MAPE. physical, mechanical, thermal morp...

Abstract This article presents the assessment of bulk and in situ mechanical properties rubber–wood–plastic composites (RubWPC) their correlations, aiming to obtain a thorough understanding behaviour RubWPC, which is an essential prerequisite realising optimal design applications. Dynamic analysis results showed that treated with multiple coupling agents (combination maleic anhydride polyethyle...

in this paper, an adaptive-network-based fuzzy inference system (anfis) is used for forecasting of natural gas consumption. it is clear that natural gas consumption prediction for future, surly can help statesmen to decide more certain. there are many variables which effect on gas consumption but two variables that named gross domestic product (gdp) and population, are selected as two input var...

Soil cation exchange capacity (CEC) is a parameter that represents soil fertility. Being difficult to measure, pedotransfer functions (PTFs) can be routinely applied for prediction of CEC by soil physicochemical properties that can be easily measured. This study developed the support vector regression (SVR) combined with genetic algorithm (GA) together with the adaptive network-based fuzzy infe...

Objective Immunosuppressant therapy plays a pivotal role in transplant success and longevity. Tacrolimus, a primary immunosuppressive agent, is well known to exhibit significant pharmacological interpatient and intrapatient variability. This variability necessitates the collection of serial trough concentrations to ensure that the drug remains within therapeutic range. The objective of this stu...

INTRODUCTION Accelerometers are commonly used to assess physical activity. Consumer activity trackers have become increasingly popular today, such as the Fitbit. This study aimed to compare the average number of steps per day using the wrist-worn Fitbit Flex and waist-worn ActiGraph (wGT3X-BT) in free-living conditions. METHODS 104 adult participants (n = 35 males; n = 69 females) were asked ...

2 Abstract In this paper, we proposed a Trajectory Reconstruction Model as an improvement to existing speed-based travel time estimation models. The proposed model utilizes point-based speed data collected by existing Intelligent Transportation Systems (ITS). Using the smoothing scheme proposed in this paper, it is possible to construct a speed surface as a function of space and time. Then, one...
