The proper management of the pediatric facial bone fracture is critical in the facial bone development. This study characterizes the surgically treated patient population suffering from facial bone fractures by the use of current data from a large series consisting of 201 cases. The data was gathered through a retrospective chart review of patients surgically treated for facial bone fractures at the department of plastic and reconstructive surgery, Sanggye Paik hospital, Inje university medical center, collected over 10-years period from January, 1993 to December, 2002. Data regarding patient demographics(age, sex), seasonal distribution, location of fractures, and the causes of injury with admission periods, were collected. In total, there were 201cases of pediatric facial bone fractures. Male patients outnumbered female patients by a 5.48: 1 ratio and were found to engage in a wider range of behaviors that resulted in facial bone fractures. Physical violence was the leading cause of pediatric facial bone fractures(27.9%), followed by sports-related mechanisms (22.9%) and falling down(17.9%). The most prevalent age group was 11-15 years-old(71.1%) and there was a 14.3% prevalence in March. Among the location of fractures, the nasal bone was the most prevalent, accounting for 82.3% of injuries, followed by the orbit(9.95%), and the mandible fractures(7.5%). Most patients(59.7%) were treated within 6-9 days after trauma and the mean hospitalization period was 8-11 days. We should follow up the surgically treated patients, and they will be further evaluated about postoperative sequele and effect on the facial bone development. These studies demonstrate differences in the demographics and clinical presentation that, if applied to patients, will enable a more accurate diagnosis and proper management.

The present study investigated whether the emotional states reading ability through facial expression changes by age(3-, 5-year-old and university student groups), sex(male, female), facial expression's presenting areas(face, eyes) and the type of emotions(basic emotions, complex emotions). 32 types of emotional state's facial expressions which are linked relatively strong with the emotional vocabularies were used as stimuli. Stimuli were collected by taking photographs of professional actors facial expression performance. Each individuals were presented with stories which set off certain emotions, and then were asked to choose a facial expression that the principal character would have made for the occasion presented in stories. The result showed that the ability of facial expression reading improves as the age get higher. Also, they performed better with the condition of face than eyes, and basic emotions than complex emotions. While female doesn't show any performance difference with the presenting areas, male shows better performance in case of facial condition compared with eye condition. The results demonstrate that age, facial expression's presenting areas and the type of emotions effect on estimation of other people's emotion through facial expressions.

In this paper, we propose a character floating hologram system using the user's gender and age. The proposed system recognizes the gender and age of the user through depth images and color images. The depth images are used to find and normalize facial position. Next, by using facial color images, the age and gender are estimated through an verified database-based model of CNN. Finally, the estimated age and gender are expressed to a character for the floating hologram. The proposed system can be used in a variety of areas, including marketing, advertising, and exhibition events using gender or age.

Background Bariatric surgeries performed in the USA has increased twelve-fold in the past two decades. The effects of rapid weight loss on facial features has not been previously studied. We hypothesized that bariatric surgery will mimic the effects of aging thus giving the patient an older and less attractive appearance. Methods Consecutive patients were enrolled from the bariatric surgical clinic at our institution. Pre and post weight loss photographs were taken and used to generate two surveys. The surveys were distributed through social media to assess the difference between the preoperative and postoperative facial photos, in terms of patients' perceived age and overall attractiveness. 102 respondents completed the first survey and 95 respondents completed the second survey. Results Of the 14 patients, five showed statistically significant change in perceived age (three more likely to be perceived older and two less likely to be perceived older). The patients were assessed to be more attractive postoperatively, which showed statistical significance. Conclusions Weight loss does affect facial aesthetics. Mild weight loss is perceived by survey respondents to give the appearance of a younger but less attractive patient, while substantial weight loss is perceived to give the appearance of an older but more attractive patient.

The author studied and analyzed statistically 112 adults female ranging in age from 18 to 20 years with normal occlusion, 56 adults female ranging in age from 18 to 24 years with deep overbite and 53 adults female ranging in age from 18 to 28 years with open bite by vertical cephalometric analysis. The results were as follows; 1. In comparing normal occlusion with deep overbite and open bite, skeletal linear measurements were more significant than dentoalveolar linear measurements. SN-MP angle, SN-OP angle, PP-OP angle and Xi angle (ANS-Xi-Pog) were significant in anglular measurements. 2. Upper posterior facial height (SE-PNS), upper anterior alveolar height, lower posterior alveolar height, lower posterior alveolar height/lower anterior alveolar height and SN-PP angle were non significant between deep overbite and open bite. 3 The most significant items between deep overbite and open bite were lower anterior facial height (ANS-ME) and SN-MP angle. 4. Correlation coefficients of angular measurements were higher in deep overbite, while that of linear measurement total anterior facial height (N-ME) was higher in open bite. 5. In the multiple regression equation, significant variables were total anterior facial height (N-ME), lower anterior alveolar height, upper anterior alveolar height, upper posterior alveolar height, Xi angle (ANS-Xi-Pog) and ramus height (AR-Go) in deep overbite, and total anterior facial height (N-Me), lower anterior alveolar height, ramus height (AR-Go), lower posterior alveolar height, PP-MP angle and upper posterior facial height (SE-PNS) in open bite.

Recently deep learning models are widely used for various tasks such as facial recognition and face editing. Their training process often involves a dataset with imbalanced age distribution. It is because some age groups (teenagers and middle age) are more socially active and tends to have more data compared to the less socially active age groups (children and elderly). This imbalanced age distribution may negatively impact the deep learning training process or the model performance when tested against those age groups with less data. To this end, we propose an age-controllable face synthesis technique using a feature decomposition to classify age from facial images which can be utilized to synthesize novel data to balance out the age distribution. We perform extensive qualitative and quantitative evaluation on our proposed technique using the FFHQ dataset and we show that our method has better performance than existing method.

Purpose: There are two theories about the relationships between facial fractures and cranial injuries. One is that facial bones act as a protective cushion for the brain, and the other is that facial fractures are the marker for increased risk of cranial injury. They have been debated on for many years. The purpose of this study is to identify the relationship between facial fractures and cranial injuries. Methods: A retrospective study was performed on 242 patients with facial fractures. The data were analyzed based on the medical records of the patients: age, gender, cause of injury, Injury Severity Score (ISS), alcohol intake, type of facial fractures, and type of cranial injury. The patients were divided into two groups: facial fractures with cranial injury and facial fractures without cranial injury. We compared the general characteristics between the two groups and evaluated the relationship between each type of facial fracture and each type of cranial injury. Results: Among the 242 patients with facial bone fractures, 96 (39.7%) patients had a combination of facial fractures and cranial injuries. Gender predilection was demonstrated to favor males: the ratio was 3:1. The mean age was $36.51{\pm}19.63$. As to the injury mechanism, traffic accidents (in car, out of car, motorcycle) were statistically significant in the group of facial fractures with cranial injury (p=0.038, p=0.000, p=0.003). The ISS was significant, but alcohol intake was not significant. No significant relationship between facial fractures and skull fractures was found. Only maxilla fractures, zygoma fractures, and cerebral concussion had a significant difference in cranial injury (p=0.039, p=0.025). Conclusion: There is a no correlation between facial fractures and skull fractures, which suggests that the cushion effect is the predominent relationship between facial fractures and cranial injuries.

Purpose: Aging society was realized after persons over 65 was rated above 7% in 2000. It is inevitable fact that society gets older. Few study about facial bone fracture in elderly was reported until now. This study provides a retrospective statistical analysis of facial bone fracture and reports of some demographical information from medical records. Methods: From January 2000 to December 2005, 123 cases of facial bone fracture in above 55 year-old persons were reviewed and analysed. Statistic data was related to distribution, age, sex, causes, occupations, occurrence, time, incidence of facial bone fracture, treatment and it's complications. Results: Facial bone fractures in elderly tend to increase and rated to 4.7%. Facial bone fractures in elderly were most frequently occurred in farmers, cultivator accidents and zygoma fractures. A few minor complications were checked, but easily improved. Conclusion: Facial bone fractures in elderly have small proportion of the whole facial bone fractures, but gradually have been increased. This study was observed trends in changes of facial bone fracture in elderly for 5 years and expected to provide statistical index to prevent facial bone fracture in elderly.

There are no authentic solutions in a face region extraction problem though it is an important part of pattern recognition and has diverse application fields. It is not easy to develop the facial region extraction algorithm because the facial image is very sensitive according to age, sex, and illumination. In this paper, to solve these difficulties, a fuzzy color filer based on the facial region extraction algorithm is proposed. The fuzzy color filter makes the robust facial region extraction enable by modeling the skin color. Especially, it is robust in facial region extraction with various illuminations. In addition, to identify the fuzzy color filter, a linear matrix inequality(LMI) optimization method is used. Finally, the simulation result is given to confirm the superiority of the proposed algorithm.
