Objectives : Facial Nerve Paralysis is one kind of common diseases and it can be treated by natural therapy and the efficiency of treatment is relatively high. In clinical trial, it is not difficult to find patients who were not completely recovered from Facial Nerve Paralysis, so the symptoms are fixed permanently. This leads many doctors and patients to have interests in the progress and prognosis of the disease, so this study was to analyze clinical prognosis factors and verify the effects of Electrodiagnostic Test. Methods : The 378 subjects were chosen from 987 patients who were suffering from Peripheral Facial Palsy, diagnosed with Bell's palsy and Ramsay Hunt Syndrome and had admission treatment. They got Oriental-Western Medicine Treatment within two weeks after outbreaks of the disease and treated at least over 3 weeks using Oriental-Western Medicine Treatment. Results : 1. There was a significant difference in the results of treatment according to gender, age, types of Facial Palsy, existence of Post Auricular Pain, existence of Labyrinth Symptom, HBGS, and existence of onsets of recovery as clinical prognosis factors of Peripheral Facial Palsy, However, a statistically significant difference was not shown in the results of treatment according to the position of Facial Palsy(left or right), existence of a relapse, and diabetes, hypertension. 2. As a result of overall treatment, 77.2% of patients were recovered almost entirely and 22.8% were not, and the quelae of incomplete recovery were Synkinesis, facial contracture, facial spasm, crocodile tears and scheroma in order of frequency. 3. The results of electrodiagnostic test represented useful correlation to predict the final effects of treatment. Conclusion : Based on the above results, the prognosis factors, the degree of recovery, and the sequelae of incomplete recovery were analysed and the effects of electrodiagnostic test was verified.

Because many of patients seeking orthodontic treatment worry about the facial appearance and their chief motivation for orthodontic treatment is facial esthetics, it is critical to understand the influence of gender or culture on the evaluation of profile esthetics. The purpose of this study was to find out any influence of gender or culture on judging good facial profile. 4 different groups were asked to evaluate 133 facial profiles to test the influence of gender or culture on judging good facial profiles. Those 4 groups consisted of 10 Korean males, 10 Korean females, 10 Korean American males, and 10 Korean American females. 2 evaluation systems were introduced, absolute and relative. Soft tissues of selected good profile group were analyzed and statistic analysis was performed. Conclusions were as follows 1. Inter-evaluator difference for judging good facial profile was statistically significant, even if there was general agreement for the best profile among 40 raters. 2. Gender difference under the same cultural environment was not significant statistically. 3. The same ethnic groups with different cultural background showed statistically different preference on judging good Profile. 4. Good facial profile group had their own characteristics compared to remaining group in several soft tissue measurements which were vertical facial ratio, soft tissue facial convexity, and antero-posterior relative lip position.

Emotion recognition is one of the most important and challenging areas of computer vision. Nowadays, many studies on emotion recognition were conducted and the performance of models is also improving. but, more research is needed on emotion recognition and sentiment analysis of video viewers. In this paper, we propose an emotion analysis system the includes a sentiment analysis model and an interest prediction model. We analyzed the emotional patterns of people watching popular and unpopular videos and predicted the level of interest using the emotion analysis system. Experimental results showed that certain emotions were strongly related to the popularity of videos and the interest prediction model had high accuracy in predicting the level of interest.

This study is a preliminary study to design a character automation system that considers the facial characteristics of mammals. The experimental data of this study was conducted on dogs (dog breeds) and humans, which were designed to be used in many contents. First, data was extracted from 100 types of dogs and 100 human data. Second, the criteria for measuring the ratio of important parts of the dog and human face were suggested. In addition, a comparative analysis of the face of a dog and a human face is conducted. Lastly, by analyzing the main component(PCA), the most characteristic elements in the faces of dogs and humans were analyzed. As a result, it was confirmed that the length of the face, the size of the eyes, the length of the glabellar, and the length of the glabellar and other parts are important. Through this study, the features of the dog's face that are different from humans are expected to contribute to the animal character automation.

The purposes of this study were to find out any significants among somatotypes and face types and importance of image making to successful students' life. The respondents were composed of 181 males and 160 females. It consists of total 29 items including the facial features, personality expression methods, characteristics of body shapes, image making, colors and neckline and their responses were measured with Likert 5-point scale. For data analysis, descriptive statistics, cross-tabulation analysis including $Χ^2$-test and frequency analysis were used. As the results, 47％ of male students and 28% of female students responded they were satisfied with their own facial types. 32% of male students and all female students were not satisfied with their own body shapes and fashion depends on accessories like hat, sunglasses, boots and necklace rather than dress itself. All male and female students were not satisfied with their body shapes and recognized the importance of image. They answered that they change image if someone advices their image and it suggests that information and intellectual needs of image making are required and approach to efficient methods of image making is needed.

This paper introduces an adaptive face recognition method based on a Novel Incremental Kernel Nonparametric Discriminant Analysis (IKNDA) that is able to learn through time. More precisely, the IKNDA has the advantage of incrementally reducing data dimension, in a discriminative manner, as new samples are added asynchronously. Thus, it handles dynamic and large data in a better way. In order to perform face recognition effectively, we combine the Gabor features and the ordinal measures to extract the facial features that are coded across local parts, as visual primitives. The variegated ordinal measures are extraught from Gabor filtering responses. Then, the histogram of these primitives, across a variety of facial zones, is intermingled to procure a feature vector. This latter's dimension is slimmed down using PCA. Finally, the latter is treated as a facial vector input for the advanced IKNDA. A comparative evaluation of the IKNDA is performed for face recognition, besides, for other classification endeavors, in a decontextualized evaluation schemes. In such a scheme, we compare the IKNDA model to some relevant state-of-the-art incremental and batch discriminant models. Experimental results show that the IKNDA outperforms these discriminant models and is better tool to improve face recognition performance.

The purpose of this study is to figure out the information needed to improve the shape and size suitability of face-applied mask sheets. The study analyzed the shape of the mask sheet from the scanned images of 50 products of 37 domestic brands. In addition, each measurement of 42 mask sheets were compared and analyzed multilaterally with the 3D measurement dimensions of the faces of men and women in their 20s from the 6th SizeKorea data. Analysis on the shapes of mask sheets indicated that domestic commercial mask sheets are mainly made of single or dual sheets, with slits for enhancing fitness to the three-dimensional face. In the dimensional analysis of Korean men, women and mask sheets, most of the lengths of the mask sheets were significantly larger or smaller than the actual faces of men and women. The horizontal length and vertical length of the forehead above the eyes are significantly shorter, thereby requiring adjustments in the dimensions of this area. In order to improve the size suitability of the mask, it is necessary to adjust the dimensions of the problem area according to the research results as well as diversify the dimensions considering the target layer.

Analysis of lateral cephalometric radiograph (cephalogram) has been used routinely to evaluate skeletal and dental relationships, but analysis of the lateral facial photograph has not been used frequently for evaluation of skeletal relationships. As concerns about harm of X-ray irradiation increases, this study was planned to evaluate the possibility of substituting analysis of the lateral cephalogram with analysis of the lateral facial photograph by comparing these two analyses. According to the ANB values from cephalometric analysis, subjects were divided into three groups: Class I malocclusion group (n=32). Class II malocclusion group (n=32), and Class III malocclusion group (n=31). After measurements of angles indicating horizontal and vertical relationships of the maxilla and mandible on the lateral cephalograms and photographs, differences between Class I, II and III groups were evaluated. To evaluate the similarity between two similar values in the cephalograms and photographs, t-test using standardized variable Z and correlation analysis were performed in the Class I malocclusion group. The results showed that 1) SnN'Pg' on the photograph can be used to evaluate the antero-posterior relationship of the maxilla and mandible (ANB), 2) N'-Sn/Sn-Pg' on the photograph can be used to evaluate facial convexity (NA/APg), 3) Sn-Tra-Me' on the photograph can be used as a measurement similar to FMA. In conclusion, partly substituting lateral cephalogram analysis with lateral facial photograph analysis was possible in the evaluation of the maxilla and mandible.

This study investigates the effect of nonverbal communication on trust, switching barrier, and repurchase intention. Sample subjects used in this study were customers of a fashion shop in Sunchon. The questionnaires were conveniently sampled from July 2010 to August 2010. Questionnaire data from 335 customers of a national brand were analyzed through a reliability analysis, factor analysis, and multiple regression analysis. The results of this study are as follows. First, nonverbal communication by the service provider was divided into 3 types, physical appearance and paralanguage, postures and proxemics, and facial expressions. Second, it was found that physical appearance and paralanguage, postures and proxemics, facial expression of nonverbal communication had a significant impact on customer trust. Third, given the relationship between nonverbal communication and switching barrier, it was represented that the postures and proxemics and facial expressions (except physical appearance and paralanguage) had a significantly positive influence on the switching barrier. Forth, physical appearance/paralanguage, postures/proxemics, and facial expressions (nonverbal communication) had a positive influence on repurchase intention. Fifth, given the relationship between trust and repurchase intention as well as switching barrier and repurchase intention, it was represented that trust and switching barrier have a significantly positive influence upon repurchase intention. According to the results of this study, the more positive nonverbal communication by the service provider then the higher the customer repurchase intention as well as trust and switching barrier. Fifth, given the relationship between trust and repurchase intention as well as switching barrier and repurchase intention, it was represented that trust and switching barrier have a significantly positive influence upon repurchase intentions.

This study was performed to establish the cephalometric standards and to compare measurement of Korean children in the Field I, II, III, IV, V, VI to Japanese and Caucasians by the Ricketts' analysis. Lateral cephalograms of 24 males and 27 females with normal occlusion and acceptable profile 9 years of age were obtained and statistically analyzed. 1. Norms of Korean males, females and both sexes at 9 years old were established. 2. Significant differences between male and female exist in incisor overjet, maxillary incisor protrusion, mandibular incisor inclination, cranial deflection, corpus length. Maxillary incisor of male was more protrude and overjet was larger than female 3. Korean was similar to Japanese but different from Caucasian. Compare with facial axis and facial depth, chin was retruded dolichofacial pattern and due to large mandibular plane angle and small corpus length, mandibular plane was inclined and mandible body was short. Compare with porion location, ramus position and posterior facial height, ramus was long and located posterior. Compare with maxillary depth and maxillary height, maxilla was located posterior and inferior. The distance between the upper molar and PTV was short, the amount of distalization is limited. Maxillary and mandibular incisor were more protruded and also lower lip was more protruded to esthetic line 4. In comparison between 9 and 11 years old, growth changes of facial depth, mandibular plane angle, corpus length and upper molar position were larger than that of Japanese and Caucasians.
