Objectives: This study aimed to find out the characteristics of patients with facial palsy based on the National Health Insurance(NHI) statistical yearbook and provide the information pertaining to supplement Coverage of NHI. Methods: Based on the data of NHI between 2004 to 2021 for facial palsy(G51) obtained from the Ministry of Health and Welfare, the analyses were carried out according to the distribution of gender and the number of patients, visits, reimbursed days, and medical expenses by using the SAS 9.4. Results: The crude rate of facial palsy was reported as 361.71(2021) comparable with 419.60(2004) and 534.11(2009). The rate of men increased from 293.96(2004) to 302.27(2021) but the rate of women decreased from 450.88(2014) to 420.80(2021). The number of patients maintained around 190,000, however, it declined for patients treated Korean medicine(KM) after 2010. As the medical expenses were elevated, especially Western medicine(WM), that of WM exceeded KM's since 2018. The expenses of women were higher than men's in KM. By contrast, there was no difference with gender in WM. For reimbursed days per visits, it has been increased in WM but there was no difference in KM. Conclusion: Although the rate of patients with facial palsy in KM was high with no difference in the whole number of patients and reimbursed days per visits in KM annually, the number of patients in KM decreased but medical expenses elevated. According to this, it is necessary for reinforcing Coverage of NHI to research other factors related to KM.

We propose an emotional training framework that can determine the initial symptom of schizophrenia by using emotional analysis method through facial expression change. We use Emotion API in Microsoft to obtain facial expressions and emotion values at the present time. We analyzed these values and recognized subtle facial expressions that change with time. The emotion states were classified according to the peak analysis-based variance method in order to measure the emotions appearing in facial expressions according to time. The proposed method analyzes the lack of emotional recognition and expressive ability by using characteristics that are different from the emotional state changes classified according to the six basic emotions proposed by Ekman. As a result, the analyzed values are integrated into the image color transfer framework so that users can easily recognize and train their own emotional changes.

Objectives : To assess the characteristics of electropyography(EMG) and heart rate variability(HRV) values in idiopathic facial palsy inpatients of different Sasang constitutions. Methods : Medical records of 103 idiopathic facial palsy inpatients who underwent facial EMG testing and HRV testing were retrospectively reviewed. All subjects had been consulted to the department of Sasang constitution for constitution differentiation. The Sasang constitutional and age distribution were initially analyzed, and axonal loss percentage values on EMG were correlated with Sasang constitution and sex. HRV results were also correlated with Sasang constitution and sex. Results : 1. 24.4 percent of idiopathic facial palsy inpatients were of the Soyang constitution, 52.4 percent were of the Taeum, and 23.3 percent were of the Soeum. Patients in their fifties were most common in all constitutions(27.8%). 2. Mean axonal loss values for the temporal, zygomatic, and buccal branches were all statistically significantly lower in the Taeum constitution compared with Soyang or Soeum(p<0.05). 3. Mean axonal loss values for the temporal, zygomatic, and buccal branches were all statistically significantly lower in men than women(p<0.05). 4. The mean LF/HF ratio was significantly lower in idiopathic facial palsy inpatients of the Soeum constitution compared with Soyang and Taeum(p<0.05), but there was no statistically significant difference in mean MHRT, SDNN, TP, VLF, LF, and HF of different constitutions. 5. The mean SDNN was significantly lower in women inpatients compared with men(p<0.05), but there was no statistically significant difference in mean MHRT, TP, VLF, LF, HF, and LF/HF ratio. Conclusions : The Sasang constitutional composition of idiopathic facial palsy inpatients closely adheres to the composition proposed in Dong-eui-su-se-bo-won, but the Taeum and Soeum proportion is slightly larger and the Soyang proportion slightly smaller. Axonal loss value on EMG was significantly lower in the Taeum constitution, and in men(p<0.05, <0.05). Mean LF/HF ratio was significantly lower in the Soeum constitution compared with Soyang and Taeum(p<0.05), and mean SDNN was significantly lower in women(p<0.05).

In this paper, knowledge based text to facial sequence image system for interaction of lecturer and learner in cyber universities is studied. The system is defined by the synthesis of facial sequence image which is synchronized the lip according to the text information based on grammatical characteristic of hangul. For the implementation of the system, the transformation method that the text information is transformed into the phoneme code, the deformation rules of mouse shape which can be changed according to the code of phonemes, and the synthesis method of facial sequence image by using deformation rules of mouse shape are proposed. In the proposed method, all syllables of hangul are represented 10 principal mouse shape and 78 compound mouse shape according to the pronunciation characteristics of the basic consonants and vowels, and the characteristics of the articulation rules, respectively. To synthesize the real time facial sequence image able to realize the PC, the 88 mouth shape stored data base are used without the synthesis of mouse shape in each frame. To verify the validity of the proposed method the various synthesis of facial sequence image transformed from the text information is accomplished, and the system that can be applied the PC is implemented using the proposed method.

Gabriel-de Vries syndrome, caused by the mutation of YY1, is a newly defined genetic syndrome characterized by developmental delay, facial dysmorphism, and intrauterine growth retardation. A 7-month-old girl presented developmental delay and subtle facial dysmorphism including facial asymmetry, micrognathia, and low-set ears. Whole exome sequencing identified a de novo heterozygous missense variant in the YY1 (c.1220A>G; p.His407Arg) gene. Here, we examined the clinical and genetic characteristics of an infant with a novel likely pathogenic variant of YY1. This case expands the phenotypic spectrum of Gabriel-de Vries syndrome.

Objectives Schizophrenic patients have been shown to be impaired in both emotional self-awareness and recognition of others' facial emotions. Alexithymia refers to the deficits in emotional self-awareness. The relationship between alexithymia and recognition of others' facial emotions needs to be explored to better understand the characteristics of emotional deficits in schizophrenic patients. Methods Thirty control subjects and 31 schizophrenic patients completed the Toronto Alexithymia Scale-20-Korean version (TAS-20K) and facial emotion recognition task. The stimuli in facial emotion recognition task consist of 6 emotions (happiness, sadness, anger, fear, disgust, and neutral). Recognition accuracy was calculated within each emotion category. Correlations between TAS-20K and recognition accuracy were analyzed. Results The schizophrenic patients showed higher TAS-20K scores and lower recognition accuracy compared with the control subjects. The schizophrenic patients did not demonstrate any significant correlations between TAS-20K and recognition accuracy, unlike the control subjects. Conclusions The data suggest that, although schizophrenia may impair both emotional self-awareness and recognition of others' facial emotions, the degrees of deficit can be different between emotional self-awareness and recognition of others' facial emotions. This indicates that the emotional deficits in schizophrenia may assume more complex features.

Facial expression is an important means of representing characteristics in movies and animations, and facial capture technology can support the production of facial animation for 3D characters more quickly and effectively. Blendshape techniques are the most widely used methods for producing high-quality 3D face animations, but traditional blendshape often takes a long time to produce. Therefore, the purpose of this study is to achieve results that are not far behind the effectiveness of traditional production to reduce the production period of blend shape. In this paper, in order to make a blend shape, the method of using the cross-model to convey the blend shape is compared with the traditional method of making the blend shape, and the validity of the new method is verified. This study used kit boy developed by Unreal Engine as an experiment target conducted a facial capture test using two blend shape production techniques, and compared and analyzed the facial effects linked to blend shape.

Skin replacement in large cheek defects after excision of benign or malignant tumor on the face is a challenging task. The physical characteristics of cheek skin are matched best by adjacent skin. Various methods of reconstructing of the facial surface such as forehead flap, distant flap, or a full thickness or split thickness skin graft have replaced adjacent tissue for coverage in many cases. We have reviewed ten cases of aesthetic reconstruction of the face after resection of the facial skin tumor within the last 5 years. The first group of 3 patients were reconstructed with split thickness skin graft from the scalp or lower abdomen. The second group of patients were reconstructed with cheek flap. The third group of 3 patients were reconstructed with cervicofacial flap. The last 2 patients were reconstructed with nasolabial flap & island falp respectively. The advantages from our experience with various method of coverage are its hidden donor area & good color match with the facial skin & increased success rate.

By observing the correlationships between the characteristics of the facial pattern and the methods of establishing the position of the lower central incisor to the five reference lines on the lateral roentgenocephalograms, the author tried to find the most useful method of them, the criteria of which were the independence of a variation according to facial patterns, the close relationships with soft tissue and lip balance, and the simple and consistent usefulness in clinical practice. The subject consisted of forty normal occlusions, forty class II div I malocclusions, forty class III malocclusions, ten treated claas II div 1 cases and ten treated class III cases, all were in 14-17 yrs of age. The findings of this study are as follows: 1. The position of the lower central incisor to EP, OP, MP and NB showed variations according to ANB, FMA, facial convexity and Holdaway angle. 2. The position of the lower central incise. to AP line (A-Pog) was not co..elated with ANB, FMA, facial convexity and Holdaway angle, so it can be used consistently, regardlesss of the facial pattern. 9. The lineal position of the incisal edge of the lower central incisor to AP line has a profound influence on harmonious soft tissue and lip balance.
