Recently, due to the introduction of high-tech equipment in interactive exhibits, many people’s attention has been concentrated on Interactive exhibits that can double the exhibition effect through the interaction with the audience. In addition, it is also possible to measure a variety of audience reaction in the interactive exhibition. Among various audience reactions, this research uses the change of the facial features that can be collected in an interactive exhibition space. This research develops an artificial neural network-based prediction model to predict the response of the audience by measuring the change of the facial features when the audience is given stimulation from the non-excited state. To present the emotion state of the audience, this research uses a Valence-Arousal model. So, this research suggests an overall framework composed of the following six steps. The first step is a step of collecting data for modeling. The data was collected from people participated in the 2012 Seoul DMC Culture Open, and the collected data was used for the experiments. The second step extracts 64 facial features from the collected data and compensates the facial feature values. The third step generates independent and dependent variables of an artificial neural network model. The fourth step extracts the independent variable that affects the dependent variable using the statistical technique. The fifth step builds an artificial neural network model and performs a learning process using train set and test set. Finally the last sixth step is to validate the prediction performance of artificial neural network model using the validation data set. The proposed model is compared with statistical predictive model to see whether it had better performance or not. As a result, although the data set in this experiment had much noise, the proposed model showed better results when the model was compared with multiple regression analysis model. If the prediction model of audience reaction was used in the real exhibition, it will be able to provide countermeasures and services appropriate to the audience’s reaction viewing the exhibits. Specifically, if the arousal of audience about Exhibits is low, Action to increase arousal of the audience will be taken. For instance, we recommend the audience another preferred contents or using a light or sound to focus on these exhibits. In other words, when planning future exhibitions, planning the exhibition to satisfy various audience preferences would be possible. And it is expected to foster a personalized environment to concentrate on the exhibits. But, the proposed model in this research still shows the low prediction accuracy. The cause is in some parts as follows : First, the data covers diverse visitors of real exhibitions, so it was difficult to control the optimized experimental environment. So, the collected data has much noise, and it would results a lower accuracy. In further research, the data collection will be conducted in a more optimized experimental environment. The further research to increase the accuracy of the predictions of the model will be conducted. Second, using changes of facial expression only is thought to be not enough to extract audience emotions. If facial expression is combined with other responses, such as the sound, audience behavior, it would result a better result.

There is general acceptance that a diagnosis of acute pancreatitis requires two of the following three features: 1) epigastric or upper abdominal pain characteristic of acute pancreatitis, 2) serum amylase and/or lipase ≥3 times the upper limit of normal, and 3) characteristic findings of acute pancreatitis on abdominal images such as ultrasonography, computed tomography (CT) or magnetic resonance imaging. Other pancreatic diseases and acute abdomen have been ruled out before making a diagnosis of acute pancreatitis. Serum lipase may be more useful than serum amylase because serum lipase is thought to be more sensitive and specific than serum amylase in the diagnosis of acute pancreatitis. Contrast-enhanced CT scan is the best imaging technique to rule out the conditions that masquerade as acute pancreatitis, to diagnose the severity of acute pancreatitis, and to identify complications of pancreatitis. The etiology of acute pancreatitis should be made clear as soon as possible to decide treatment policy of acute pancreatitis or to prevent the recurrence of pancreatitis. The etiology of acute pancreatitis in an emergency situation should be assessed by clinical history, laboratory tests such as serum liver function tests, measurement of serum calcium and serum triglycerides and ultrasonography. A differentiation of gallstoneinduced acute pancreatitis should be given top priority in its etiologic diagnosis because early endoscopic retrograde cholangiopancreatography should be considered if a complication of cholangitis and a prolonged passage disorder of the biliary tract are suspected.

This review article deals with the optimal management of chemotherapy-related adverse events which are the nausea, vomiting, diarrhea, neutropenia, peripheral polyneuropathy. Recent literatures are reviewed and pathogenetic mechanism and management of each of adverse events are summarized. It is not simple but complexed and wide. Most patients could be expected how much they feel the nausea before the chemotherapy. We could prescribe several types of antiemetic agent efficiently. When the patients suffered from the neutropenia after previous chemotherapy, we should closely monitor their blood cell count. And we could help them after giving the granulocyte colony stimulating factor. Diarrhea is one of big troublesome issue related with chemotherapy. We could control the diarrhea by reducing the dose of the chemotherapy and prescribing optimally loperamide. Cisplatin and oxaliplatin could make the patients feel paresthesia and numbness but it’s hard to reverse or prevent even though we use anticonvulsants (carbamazepine, oxcarbazepine), antidepressants (amitriptyline, venlafaxine), amifostine, nimodipine, vitamins and minerals.

Background: Quantitative measurement of allergic rhinitis (AR)-specific quality of life (QOL) impairment is important for the evaluation of its burden and efficacy of treatment. However, the QOL questionnaire for Korean AR has not yet been developed. Objective: The aim of this study is to develop and validate the QOL questionnaire for Korean AR patients. Method: We surveyed 22 AR-related items in 284 persistent AR patients and, based on the survey, developed an AR-specific Korean QOL questionnaire. The questionnaire consisted of 15 items and adapted 5-point scale for each item. We validated the questionnaire by comparing the QOL scores from 95 patients before and after the treatments with mometasone or levocetrizine. Result: The mean QOL score was lowered by 0.73 (0.33, 1.80) (P<0.001) in 30 patients with a definite improvement and by 0.63 (?0.33, 1.73) (P<0.001) in 29 patients with a slight improvement. However, the score was not significantly lowered in 17 patients without improvement [0.20 (0.00, 0.33), P=0.24]. The questionnaire was also highly reproducible with the value of intraclass correlation coefficient and interclass standard deviation as 0.996 (P<0.001) and 0.736, respectively. Conclusion: We developed and validated a Korean allergic rhinitis QOL questionnaire, and this can be used for evaluating the efficacy of treatment modalities for AR.

A two-dimensional unsteady in viscid flow solver has been developed for the simulation of complex geometric configurations on adaptive Cartesian meshes. Embedded condition was used for boundary condition and a predictor-corrector explicit time marching scheme was used for time-accurate numerical simulation. The Cartesian mesh generator, which was previously developed for steady problem, was used grid generation for unsteady flow. The solver was based on ALE formulation for body motion. For diminishing the effects of cut-cells, the cell merging method was used. Using cell merging method, it was eliminated the CFL constraints. The conservation problem, which is caused cell-type variation around region swept by solid boundary, was also solved using cell merging method. The results are presented for 2D circular cylinder and missile launching problem.
