  • In this paper, a weighted value wrinkle detection method is suggested based on the analysis on the entire facial features such as face contour, face size, eyes and ears. Firstly, the main facial elements are detected with AAM method entirely from the input screen images. Such elements are mainly composed of shape-based and appearance methods. These are used for learning the facial model and for matching the face from new screen images based on the learned models. Secondly, the face and background are separated in the screen image. Four points with the biggest possibilities for wrinkling are selected from the face and high wrinkle weighted values are assigned to them. Finally, the wrinkles are detected by applying Canny edge algorithm for the interested points of weighted value. The suggested algorithm adopts various screen images for experiment. The experiments display the excellent results of face and wrinkle detection in the most of the screen images.

  • Background : infection associated with otalgia, herpetic eruptions, facial palsy, trigeminal pain and cochleovestibular dysfunction such as hearing dishubance, tinnitus, vertigo and other symptoms, and is not frequently encountered in otolaryngologic field. And facial paralysis occured by this syndrome is rapid in onset, usually severe in degree, and poor in prognosis. Objectives : To evaluate the Oriental Medicine's treatment and prognosis of Herpes zoster oticus and to classify of peripheral Facial palsy on Oriental Medicine. Methods : Clinical observation and analysis about a case of Ramsay-Hunt syndrome III type was done, who visited Dongguk University Gangnam Hospital. This case is managed by integrated therapy of oriental and western medicine. In oriental medicine, to treate ear pain, heonggae-yeongoetang(荊芥蓮翹湯) was given and to treat herpetic eruption, 8 constitution acupuncture treatement was done. In western medicine, antiviral agent, acyclovir and steroid hormone, prednisolon were treated. Result : About 6 weeks treatment, this case which has worse prognosis than Bell's palsy, was completed cured without any complication. Conclusion : 1. Futher divided classification about non-infectious and infectious facial palsy include "Ramsay Hunt Syndrome" is needed. 2. In acute state, Jeonyohwadan's (纏腰火丹) treatement can be applied, but the difference of invasion part, primary symptom such as ear pain and herpetic eruption is needed another treatment. 3. Ear pain and herpetic eruption can be treated in part of poongyeol(風熱) and subyeol(濕熱). 4. In Acupuncture treatement, Jeonyohwadan's (纏腰火丹) treatement can be applied in acute stage and guanwasa's treatement can be applied in chronic stage. but futher research is needed. 5. This case, Ramsay Hunt Syndrome IlI type, was managed by integrated therapy such as heonggae-yeongoetang(荊芥蓮翹湯), 8 constitution acupuncture treatement, acyclovir and prednisolon and this treatement was good effect.

  • Objective: This retrospective study compared the three-dimensional (3D) structure of mandibular condyles between adults with and without facial asymmetry, and whether it influences menton deviation. Methods: Sixty adult patients were classified into symmetry and asymmetry groups based on the menton deviation on postero-anterior radiographs. The right/left differences of 3D measurements were compared between the two groups, and measurements were compared separately on the right and left sides. The correlations between menton deviation and the right/left differences were analyzed. Results: The mediolateral dimension, neck length, condylar angles to the anteroposterior reference (PO) and midsagittal reference planes, and neck and head volumes showed significantly larger right/left differences in the asymmetry group compared to the symmetry group. Separate comparisons of the right and left sides between the two groups showed that the neck was significantly shorter and neck and head volumes were significantly smaller on the left side, which was deviated side in the asymmetry group. Pearson's correlation analysis showed significant positive correlations of menton deviation with right/left differences in neck length, condylar angle to the PO plane, and neck and head volumes in the asymmetry group. Conclusions: In individuals with facial asymmetry, menton deviation is associated with the right/left differences caused by a smaller condyle on the deviated side, particularly in neck length and neck and head volumes.

  • The facial expression is diverse and various among persons due to the impact of the psychology factor. Whilst the facial action is comparatively steady because of the fixedness of the anatomic structure. Therefore, to improve performance of the action unit recognition will facilitate the facial expression recognition and provide profound basis for the mental state analysis, etc. However, it still a challenge job and recognition accuracy rate is limited, because the muscle movements around the face are tiny and the facial actions are not obvious accordingly. Taking account of the moving of muscles impact each other when person express their emotion, we propose to make full use of co-occurrence relationship among action units (AUs) in this paper. Considering the dynamic characteristic of AUs as well, we adopt the 3D Convolutional Neural Network(3DCNN) as base framework and proposed to recognize multiple action units around brows, nose and mouth specially contributing in the emotion expression with putting their co-occurrence relationships as constrain. The experiments have been conducted on a typical public dataset CASME and its variant CASME2 dataset. The experiment results show that our proposed AU co-occurrence constraint 3DCNN based AU recognition approach outperforms current approaches and demonstrate the effectiveness of taking use of AUs relationship in AU recognition.

  • The main purpose of this study, based on implicit personality theory and attribution theory, was to examine whether there exist the physical attractiveness stereotype, "what is beautiful is good," in the present Korea, and if exist, what is the content of it. The index of the physical attractiveness of this study was the facial attractiveness judged by 30 female university students. The appropriateness of clothing was manipulated by 4 types of clothing perceived appropriate for two assumed situations by female university students. Three female faces having high, medium, and low attractiveness were simulated with the same body dressed four types of clothing using CAD system, and a total of 12 stimulus persons were created. A total of 524 male and female(262 of male, 262 of female) university students from 3 universities in Kwangju, Korea were participated as subjects in this study. The design for the experiment was a 3$\times$4$\times$2 randomaized factorial, with three levels of facial attractiveness (high, medium, low), and four types attire(formal-masculine, formal-feminine, casual-masculine, casual-feminine), two kinds of context (job interview, dating) in which perceptions were occurred. The data were analysed using factor analysis, MANOVA, t-test and Duncan test. The results were as follows: 1. The facial attractiveness exerted significant positive effects on the evaluation of sociability, adjustment, and potency of her in both of two assumed situations (p<.001, respectively). 2. The appropriateness of stimulus person′s clothing had significant positive erect on the evaluation of sociability of stimulus person in dating context(p<.001). 3. The gender of subjects did not influenced the trait evaluations in both of two assumed situations.

  • This study aims to provide fundamental data to develop anti-aging programs in the aspect of skin care. To attain the goal, manual therapy and low-power laser therapy were conducted separately to 8 women inthe 40's and 50's. They received the facial massage total 8 times twice a week for 4 weeks. According to the result of calculating the average and standard deviation by measuring skin elasticity of the area below their eyes and cheeks and also melanin around eyes and cheeks and conducting comparative analysis, both groups showed significant increase in elasticity and their melanin decreased significantly. The low-power laser therapy showed higher values than the manual therapy both in elasticity increase and melanin reduction; thus, it was analyzed that the low-power laser therapy more highly affects skin elasticity and the amount of melanin in facial skin is greater than that in manual therapy. Therefore, it was analyzed that skin care using low level laser can be significant in anti-aging of facial skin and can be utilized as a program for a new type of skin care.

  • Objective: The purpose of this study was to investigate the relationship between the facial skeletal patterns and the shape of the mandibular symphysis in adults with malocclusion by using a structural equation model (SEM). Methods: Ninety adults who had malocclusion and had records of facial skeletal measurements performed using cone-beam computed tomography were selected for this study. The skeletal measurements were classified into three groups (vertical, anteroposterior, and transverse). Cross-sectional images of the mandibular symphysis were analyzed using generalized Procrustes and principal component (PC) analyses. A SEM was constructed after the factors were extracted via factor analysis. Results: Two factors were extracted from the transverse, vertical, and anteroposterior skeletal measurements. Latent variables were extracted for each factor. PC1, PC2, and PC3 were selected to analyze the variations of the mandibular symphyseal shape. The SEM was constructed using the skeletal variables, PCs, and latent variables. The SEM showed that the vertical latent variable exerted the most influence on the mandibular symphyseal shape. Conclusions: The relationship between the skeletal pattern and the mandibular symphysis was analyzed using a SEM, which showed that the vertical facial skeletal pattern had the highest effect on the shape of the mandibular symphysis.

  • Introduction: Facial fractures (FFs) occur after high- and low-energy trauma; differences in associated injuries and outcomes have not been well articulated. Objective: To compare the epidemiology, management, and outcomes of patients suffering FFs from high-energy and low-energy mechanisms. Methods: We conducted a 6-year retrospective local trauma registry analysis of adults aged 18-55 years old that suffered a FF treated at the Santa Barbara Cottage Hospital. Fracture patterns, concomitant injuries, procedures, and outcomes were compared between patients that suffered a high-energy mechanism (HEM: motor vehicle crash, bicycle crash, auto versus pedestrian, falls from height > 20 feet) and those that suffered a low-energy mechanism (LEM: assault, ground-level falls) of injury. Results: FFs occurred in 123 patients, 25 from an HEM and 98 from an LEM. Rates of Le Fort (HEM 12% vs. LEM 3%, P = 0.10), mandible (HEM 20% vs. LEM 38%, P = 0.11), midface (HEM 84% vs. LEM 67%, P = 0.14), and upper face (HEM 24% vs. LEM 13%, P = 0.217) fractures did not significantly differ between the HEM and LEM groups, nor did facial operative rates (HEM 28% vs. LEM 40%, P = 0.36). FFs after an HEM event were associated with increased Injury Severity Scores (HEM 16.8 vs. LEM 7.5, P <0.001), ICU admittance (HEM 60% vs. LEM 13.3%, P <0.001), intracranial hemorrhage (ICH) (HEM 52% vs. LEM 15%, P <0.001), cervical spine fractures (HEM 12% vs. LEM 0%, P = 0.008), truncal/lower extremity injuries (HEM 60% vs. LEM 6%, P <0.001), neurosurgical procedures for the management of ICH (HEM 54% vs. LEM 36%, P = 0.003), and decreased Glasgow Coma Score on arrival (HEM 11.7 vs. LEM 14.2, P <0.001). Conclusion: FFs after HEM events were associated with severe and multifocal injuries. FFs after LEM events were associated with ICH, concussions, and cervical spine fractures. Mechanism-based screening strategies will allow for the appropriate detection and management of injuries that occur concomitant to FFs. Type of study: Retrospective cohort study. Level of evidence: Level III.

  • Objectives : Acne is a common disease that affects more than 70% of adolescents. Acne patients have a poor quality of life compared to patients with other skin diseases. We tried to demonstrate the effectiveness of acne treatment using cleansing soap which is easily used in daily life. Methods : We selected 20 students with acne symptoms on their facial skin. We made herbal Cp (Cold process) soaps using Seosiokyongsan, Kyungohkgo, Hwangryunhaedoktang and Baeksoooh and distributed them to experiment participants. We let them wash their face in the morning and evening for 6 weeks using herbal Cp soap. Prior to the experiment, their skin condition was checked and assessed using A-ONE Smart One-Click Automatic Facial Diagnosis System three times at 3-week intervals. Acne status was classified into 6 stages according to KAGS and acne status was also measured 3 times in total. After the experiment, the changes of skin were analyzed through facial analysis test. Results : Based on the KAGS classification, the condition of acne has improved as a whole. The state of moisture was gradually increased and the state of skin oil was significantly decreased after 6 weeks of using soap compared to before using soap. Conclusions : Cp soaps made from four kinds of herbal medicine are believed to improve the condition of acne by increasing the moisture of the facial skin and decreasing the skin oil content.

  • Objective : To determine the feasibility of translabyrinthine approach in the vestibular schwannoma patients, the authors reviewed eighteen consecutive cases, focusing at their functional outcome and operative complications. Materials and Method : To evaluate the functional outcome, we reviewed preoperative radiological findings such as size of tumors and location of jugular bulb as well as the preoperative neurological status including audiometric analysis and cranial nerve function in 18 patients, diagnosed as vestibular schwannoma. Also the surgical outcome was evaluated according to the functional preservation of facial nerve and incidence of the surgical complication as well as the extent of surgical resection. Results : The age of patients ranged from 21 to 62 years, with a mean of 50 years. Of 18 patients operated in our center by the translabyrinthine approach, wide exposure with total removal of the mass was possible in 16 cases (88.8%). The facial nerve was anatomically preserved in 88.8%. At six-month follow-up, facial nerve function was good(Grade I-II) in 15 patients(83%) and acceptable(I-IV) in all patients. Although the jugular bulb was highly placed is five patients, gross total resection was possible without facial nerve injury in all patients by the translabyrinthine approach. One patient experienced CSF leakage after surgery, but there was no patient with disabling deficit. Conclusion : Use of the translabyrinthine approach for removal of vestibular schwannomas resulted in good anatomical and functional preservation of the facial nerve, with minimal incidence of morbidity and no mortality. In cases of high jugular bulb impacted into mastoid bone, total removal was possible by displacing the jugular bulb with Surgicel cellulose and placement of bone wax.
