Vertical facial growth triggers the rotation of mandible to move the chin point to the downward and backward direction, which showed remarkably effective result making the less prominent chin. Recently, the intraoral removable appliance utilizing class III elastic demonstrated the vertical growth trigger mechanism. The treatment change was very fast and wearing was quite easy, compared to extraoral appliances. The purpose of this study was to verify the duration of the treatment on class III malocclusion using intraoral removable appliances, which designed to accelerate vertical facial growth. 56 patients were selected with the complaint of the protruded mandible and class III malocclusion (overjet : -3 - 0 mm, overbite : 0 - 4 mm). Information like; age at start, duration of the treatment events, type of the treatment, overjet, overbite etc. was collected and calculated. The average age of the patients delivering the initial brace was $8.75{\pm}1.10year$. Most of the anterior crossbite was resolved within 6 months. The total treatment period was $21.79{\pm}10.73months$ with the additional procedures like the alignment of anterior teeth and torque control using additional removable and fixed orthodontic appliances. The correlation study showed that patient's cooperation (p = 0.000) and the use of fixed appliance (p = 0.032) were significantly influenced on treatment duration.

Objectives: This study is designed to statistically analyze characteristics, treatment effect and prognosis of patients who were treated for the recurrent Bell's palsy Methods: This study retrospectively analyzed the medical records and telephone questionnaire of 82 patients treated with the recurrent Bell's palsy at the OO Korean Medicine hospital from August 01, 2018 to July 31, 2021. Results: The lower the EQ-VAS^® and HB scale before and after treatment, the higher the satisfaction with the treatment. The average of the number of days and duration of outpatient treatment for male was longer than that for female. The average number of days and duration of outpatient treatment in the group that received combined treatment was longer than that of patients who received Korean Medicine only. The higher the satisfaction of treatment, the higher the willingness to receive treatment in the event of recurrent facial palsy. HB scale after treatment was the lowest in their 40s, and the average value of HB scale after treatment tended to increase as age increased except for those in their 40s. Conclusion: This study showed that the lower the HB scale after treatment, the lower the EQ-VAS®, the higher the treatment satisfaction, and the higher the probability receiving treatment if the facial paralysis recurs. Those in their 10s to 40s showed excellent results after treatment. Comparatively, those in their 50s and above showed a little effect after treatment. Gender, affected side, history of facial palsy, season of onset, age, hypertension and diabetes had no statistically significance with recurrent Bell's palsy prognosis.

The influence function is used to develop criteria to detect outliers in discriminant analysis. We derive the influence function of observations that estimate the the misclassification probability in discriminant analysis for three groups. The proposed measures are applied to the facial image data to define outliers and redo the discriminant analysis excluding the outliers. The study proves that the derived influence function is more efficient than using the discriminant probability approach.

The patient, 21 years and 3 months female, complained of protrusion of lower face. There was severe procumbency of upper & lower anterior teeth. Cephalometric analysis revealed that the anteroposterior jaw relationship was normal, but the teeth was foreward on their respective basal bones, so diagnosed as bimaxillary dental prognathism. The patient underwent extraction of four Ist premolar and was treated with multibanded & direct bonding system. After 14 months, She gained good interdigitation of buccal segment and attractive facial profile.

Periodontal disease, trauma, deformity of tooth can jeopardize the esthetics of oral and maxillo-facial region. Moreover, increasing the demand and concern about the esthetics, clinicians should place high value on esthetics during periodontal treatment. Analysis of various anatomical considerations; lip line, shape and location of marginal gingiva, and biologic width; and diagnosis should be performed prior to periodontal plastic surgery.

The author performed electromyographic analysis on edentulous patients aging 52 to 77 who have upper and lower full dentures for 3 to 7 years of duration. And the graphs were recorded in physiologic rest position, incisal occlusion, molar occlusion, left lateral excursion, right lateral excursion and mandibular projection. The results obtained are as follows : 1. 80 per cent of the patients are in unilateral mastication. 2. The shorter history of edentulous mouth reveals the more electric potency. 3. Facial deviation owing to unilateral mastication is the cause of higher electric potency to the deviated site. 4. There were no difference in electric potency between mandibular projection and incisal occlusion.

The purpose of this study was to investigate proportional characteristics of soft tissue profile in Korean young adults. The sample consisted of 50 young adults(25 males and 25 females) who had pleasing profile and normal occlusion. Soft tissue proportional analysis was performed on lateral cephalograms taken in natural head position. The results were as follows : 1. Mean and standard deviation of proportional analysis were obtained. 2. Horizontal and vertical dimensions were larger in male. But facial proportion had no sexual difference except upper/lower face height (p<0.05). Upper/lower face height was larger in female than in male. 3. Vertical dimensions, except SN-ST, had high correlation with horizontal dimensions. 4. Head positioning error of natural head position was smaller than inter -individual variability of SN line.

Wrestling is one of the popular events for modern sports. It is difficult to quantitatively describe a wrestling game between athletes. And deep learning can help wrestling training by human recognition techniques. Based on the characteristics of latest wrestling competition rules and human recognition technologies, a set of wrestling competition video analysis and retrieval system is proposed. This system uses a combination of literature method, observation method, interview method and mathematical statistics to conduct statistics, analysis, research and discussion on the application of technology. Combined the system application in targeted movement technology. A deep learning-based facial recognition psychological feature analysis method for the training and competition of classical wrestling after the implementation of the new rules is proposed. The experimental results of this paper showed that the proportion of natural emotions of male and female wrestlers was about 50%, indicating that the wrestler's mentality was relatively stable before the intense physical confrontation, and the test of the system also proved the stability of the system.
