This study is about a speech recognition error correction system designed to detect and correct speech recognition errors before natural language processing to increase the success rate of intent analysis in natural language processing with optimal efficiency in various service domains. An encoder is constructed to embedded the correct speech token and one or more error speech tokens corresponding to the correct speech token so that they are all located in a dense vector space for each correct token with similar vector values. One or more utterance tokens within a preset Manhattan distance based on the correct utterance token in the dense vector space for each embedded correct utterance token are detected through an error detector, and the correct answer closest to the detected error utterance token is based on the Manhattan distance. Errors are corrected by extracting the utterance token as the correct answer.

Objective: This study was aimed at investigating the effects of lumbar stabilization exercise according to correct verbal instructions in pain and muscle strengthening of the low back pain patients. Design: A randomized controlled trial. Methods: Twenty subjects with low back pain were selected. They were randomly assigned to one of two groups (10 in each group): namely the lumbar stabilization exercise and lumbar stabilization exercise according to the correct verbal instructions group. The lumbar stabilization exercise group performed lumbar stabilization exercises for 6 weeks (5 times a week). The lumbar stabilization exercise according to correct verbal instructions group performed lumbar stabilization exercise according to correct verbal instructions for 6 weeks (5 times a week). We measured pain, muscle power, proprioception, and body balance before and after exercise by using visual analog scale (VAS), digital handheld dynanometer, Joint repositioning error, time up and go test respectively. Results: We found statistically significant differences in pain, muscle power, proprioception, and body balance in lumbar stabilization exercise and lumbar stabilization exercise according to correct verbal instructions group, before and after (p<0.05). Conclusions: We confirmed the effect of lumbar stabilization exercise according to correct verbal instructions. Thus we thought these results could be used as basic data and reference for low back pain. But we need more study effect of correct verbal instructions on other exercises.

One of the factors that have the greatest influence on the error of the question answering system that finds and provides answers to natural language questions is the step of searching for documents or passages that contain correct answers. In order to improve the retrieval performance, it is necessary to understand the characteristics of documents and passages containing correct answers. This paper experimentally analyzes how many question words appear in the correct answer documents, how the location of the question word is distributed, and how the topic of the question and the correct answer document are similar using the corpus composed of the question, the documents with correct answer, and the documents without correct answer. This study explains the causes of previous search research results for question answer system and discusses the necessary elements of effective search step.

An investigation was undertaken of the optimal discriminant model for predicting the likelihood of insolvency in advance for medium-sized firms based on the technology evaluation. The explanatory variables included in the discriminant model were selected by both factor analysis and discriminant analysis using stepwise selection method. Five explanatory variables were selected in factor analysis in terms of explanatory ratio and communality. Six explanatory variables were selected in stepwise discriminant analysis. The effectiveness of linear discriminant model and logistic discriminant model were assessed by the criteria of the critical probability and correct classification rate. Result showed that both model had similar correct classification rate and the linear discriminant model was preferred to the logistic discriminant model in terms of criteria of the critical probability In case of the linear discriminant model with critical probability of 0.5, the total-group correct classification rate was 70.4% and correct classification rates of insolvent and solvent groups were 73.4% and 69.5% respectively. Correct classification rate is an estimate of the probability that the estimated discriminant function will correctly classify the present sample. However, the actual correct classification rate is an estimate of the probability that the estimated discriminant function will correctly classify a future observation. Unfortunately, the correct classification rate underestimates the actual correct classification rate because the data set used to estimate the discriminant function is also used to evaluate them. The cross-validation method were used to estimate the bias of the correct classification rate. According to the results the estimated bias were 2.9% and the predicted actual correct classification rate was 67.5%. And a threshold value is set to establish an in-doubt category. Results of linear discriminant model can be applied for the technology financing banks to evaluate the possibility of insolvency and give the ranking of the firms applied.

Background and Purpose : Though there were many clinical studies of acupuncture effects they didn't have appropriate control group. So we didn't say it was true acupuncture effect, though subjects in clinical study improved. To investigate the possibility of sham acupuncture application, we examined how well subjects distinguished real acupuncture from sham acupuncture. Methods : We investigate the possibility of sham acupuncture application as the following 3 kinds of methods. 1. The public (n=60) and Oriental Medicine Doctors (n=20) looked at the appearance of acupuncture and then were treated with randomly allocated acupuncture and judged it as real or sham. 2. The public (n=60) and Oriental Medicine doctors (n=20) were treated with randomly allocated acupuncture, then they looked at the appearance of acupuncture and judged it as real or sham. 3. The public (n=60) were treated with randomly allocated acupuncture (right-real-left-sham), (right-sham-left-real), (left-real-right-sham), (left-sham-right-real), then they judged it as real or sham. Results : 1. When the public (n=60) looked at the acupuncture appearance, the correct judgement ratio was 63.3%. After they were treated with acupuncture, the correct judgement ratio was 50.0%. 2. When Oriental Medicine doctors (n=20) looked at the acupuncture appearance, the correct judgement ratio was 25.0%. After they were treated with acupuncture, the correct judgement ratio was 45.0%. 3. When the public (n=60) were treated with acupuncture, the correct judgement ratio was 50.0%. After they looked at the acupuncture appearance, the correct judgement ratio was 63.3%. 4. When Oriental Medicine doctors (n=20) were treated with acupuncture, the correct judgement ratio was 65.5%. After they looked at the acupuncture appearance, the correct judgement ratio was 65.0%. 5. After the public (n=60) were treated with randomly allocated sham or real acupuncture as (right-real-left-sham), (right-sham-left-real), (left-real-right-sham), or (left-sham-right-real). the correct judgement ratio was 66.7% in looking at the acupuncture appearance group, and in not looking at 60.0%. Conclusion : These results indicated that Kim Sham Acupuncture could apply to the double blind clinical study of acupuncture effect. And more continuous studies are needed on Sham Acupuncture apparatus.

The purpose of this study was to propose a preliminary norm for 'Korean-Test of Articulation for Children(K-TAC)'. The K-TAC was designed to test 19 Korean consonants in various phonetic contexts through 37 words. We collected the data of 220 normally developing children aged 2;6(years;months) to 6;5. We analyzed the mean percentage of consonants correct and the age of acquisition for K-TAC. The results were as follows: first, The mean percentage was over 60% at late 2 years of age, over 80% at th age of 3, and over 90% after the age of 4. There were significant differences among age groups. Second, based on the criterion of correct production by 75% of children, Korean children acquired stops and nasals except for SF velars, glottal fricative, SF liquid and affricates by late 2 or 3 years of age. After that they acquired SF velars at the age of 4 and SI liquid at the age of 5. However, they could not acquire alveolar fricatives by the age of late 6. Third, if the distorted sounds were scored as correct, they acquired SI liquid at 4 years of age and alveolar fricatives at 5 years of age.

The primary procedural components of deviated nose correction are as follows: osteotomy to correct bony deviation, septal deviation correction, manipulation of the dorsal septum to correct upper lateral cartilage deviation, and correction of functional problems (manipulation for correction of internal valve collapse and hypertrophy of the inferior turbinate). The correction of tip and nostril asymmetry cannot be overemphasized, because if tip and nostril asymmetry is not corrected, patients are unlikely to provide favorable evaluations from an aesthetic standpoint. Tip asymmetry, deviated columella, and resulting nostril asymmetry are primarily caused by lower lateral cartilage problems, which include deviation of the medial crura, discrepancy in the height of the medial crura, and asymmetry or deformity of the lateral crura. However, caudal and dorsal septal deviation, which is a more important etiology, should also be corrected. A columellar strut graft, correction of any discrepancy in the height of the medial crura, or lateral crural correction is needed to correct lower lateral cartilage deformation depending on the type. In order to correct caudal septal deviation, caudal septal shortening, repositioning, or the cut-and-suture technique are used. Surgery to correct dorsal septal deviation is performed by combining a scoring and splinting graft, a spreader graft, and/or the clocking suture technique. Moreover, when correcting a deviated nose, correction of asymmetry of the alar rim and alar base should not be overlooked to achieve tip and nostril symmetry.

Platform Screen Door(PSD) has been installed in train manual operation section(ATS/ATC) by SeoulMetro since 2005. PSDs are now operating at 17 stations in SeoulMetro lines. As a result, it increases the safety of passenger, makes a comfortable platform and saves the energy of air conditioning. For PSD operation, train shall stop within 600mm of the train stop reference point. In train manual operation section, the detection system of train position is required to notify the train driver of train position and to ensure the condition that train stops the correct position for PSD operation. To detect the train stop position, the optical sensor shall be installed at platform. However, in case of SeoulMetro lines, the detection criterions of the train correct position stop are different because of using various types of trains which have different size and shape of front cars. In this paper, to solve this problem, the precise detection algorithm of the train stop at the correct position is used, and Laser distance measure sensor is introduced to notify the distance form the reference point of the train correct stop to train driver. This system has been applying to Seoul Metro line total.
