  • 관골 골절을 분류할 때 주위의 해부학적인 구조물과 연관해서 기능적인 면에 중점을 두어야 하므로 복시나 내안증같은 합병증이 나타날 수 있는 안와골절을 포함하는 분류를 해야한다. 관골 골절의 변위에 따라 나타나는 합병증의 양상이 매우 다양하므로 진단에 도움이 될 수 있도록 지속적인 연구가 필요할 것으로 사료되며, 초창기에 이러한 임상적인 합병증이 나타나지 않더라도 추후에 발생할 가능성이 있기 때문에 이를 간과해서는 안될 것으로 사료된다.

  • In the context of contemporary digital media, virtual influencers have become an increasingly important form of socialization and entertainment, in which emotional expression is a key factor in attracting viewers. In this study, we take Luo Tianyi, a Chinese virtual influencer, as an example to explore how emotions are expressed and perceived through facial expressions in different types of videos. Using Paul Ekman's Facial Action Coding System (FACS) and six basic emotion classifications, the study systematically analyzes Luo Tianyi's emotional expressions in three types of videos, namely Music show, Festivals and Brand Cooperation. During the study, Luo Tianyi's facial expressions and emotional expressions were analyzed through rigorous coding and categorization, as well as matching the context of the video content. The results show that Enjoyment is the most frequently expressed emotion by Luo Tianyi, reflecting the centrality of positive emotions in content creation. Meanwhile, the presence of other emotion types reveals the virtual influencer's efforts to create emotionally rich and authentic experiences. The frequency and variety of emotions expressed in different video genres indicate Luo Tianyi's diverse strategies for communicating and connecting with viewers in different contexts. The study provides an empirical basis for understanding and utilizing virtual influencers' emotional expressions, and offers valuable insights for digital media content creators to design emotional expression strategies. Overall, this study is valuable for understanding the complexity of virtual influencer emotional expression and its importance in digital media strategy.

  • 본 연구에서는 얼굴 그리드 각도를 특징공간으로 하는 새로운 모델 기반 얼굴 표정 인식 방법을 제안한다. 제안 방식은 6가지 얼굴 대표 표정을 인식하기 위해 표정 그리드를 이용하여 그리드의 각 간선과 정점이 형성하는 각도를 기반으로 얼굴 특징 공간을 구성한다. 이 방법은 다른 표정 인식 알고리즘의 정확도를 낮추는 원인인 변환, 회전, 크기변화와 같은 어파인 변환에 강건한 특징을 보인다. 또한, 본 연구에서는 각도로 특징공간을 구성하고 이 공간 내에서 Wrapper 방식으로 특징 부분집합을 선택하는 과정을 설명한다. 선택한 특징들은 SVM, 3-NN 분류기를 이용해 분류하고 분류 결과는 2중 교차검증을 통해 검증하도록 한다. 본 연구가 제안한 방법에서는 94%의 표정 인식 결과를 보였으며 특히 특징 부분집합 선택 알고리즘을 적용한 결과 전체 특징을 이용한 경우보다 약 10%의 인식율 개선 효과를 보인다.

  • Objectives: Injuries of neurologic structures during parotid surgery are sometimes unavoidable even in benign tumors. Since the major postoperative neurologic complications such as facial nerve palsy and Frey's syndrome give a serious and heavy burden to both patients and surgeons, it is very important to know detailed information concerning risk factors, the incidence of complication, possibility of recovery, and the term before complete recovery. Materials and Methods: This report was based on 95 patients with parotid gland tumor who had been treated and followed up over 1 year at department of surgery and otolaryngology, chonnam university hospital. Results: 1) Among total 95 cases, the facial nerve palsy developed in 18 cases(l8.9%) and Frey's syndrome in 6 cases(6,3%). 2) The incidence of facial nerve palsy increased in cases with large tumor size, and in those operated with bipolar method. However, we didn't find out relationships between the incidence of facial palsy, localization, and histologic type. 3) The incidence of Frey's syndrome showed an increasing tendency in the cases with large tumor size, benign nature, and in those underwent superficial lobectomy with posterior approach, without a statistical significance. Conclusions: Risk of facial nerve palsy, especially a transient form, seems to be related to tumor size and bipolar coagulation method. Although Frey's syndrome tends to develop easily in the cases treated with superficial lobectomy under the diagnosis of benign tumor, a futhermore study is suggested to obtain a statistical significance.

  • 본 논문은 얼굴 모션 데이터를 벡터 기반 캐리커처의 얼굴에 적용하여 캐리커처 얼굴 표정 애니메이션을 생성할 수 있도록 하는 방법론을 기술한다. 본 방법은 일러스트레이터의 플러그인 형식으로 구현하였으며, 별도의 사용자 인터페이스를 갖추고 있다. 실험에 사용된 얼굴 모션 데이터는 28개의 소형 마커를 배우 얼굴의 주 근육 부분에 부착하고 다양한 다수 개의 표정을 Facial Tracker로 캡처한 것이다. 캐리커처는 모션데이터와의 연결을 위해 모션 캡처를 할 때 배우의 얼굴에 부착된 주요 마커의 위치와 동일한 부위에 각각의 제어점을 가진 베지어 곡선 형태로 제작되었다. 그러나 얼굴 모션 데이터는 캐리커처에 비하여 공간적인 규모가 너무 크기 때문에 모션 캘리브레이션 과정을 거쳤으며, 사용자로 하여금 수시로 조절이 가능하게 하였다. 또한 캐리커처와 마커들을 연결시키기 위해서는 사용자가 얼굴 부위의 각 명칭을 메뉴에서 선택한 다음, 캐리커처의 해당 부위를 클릭함으로써 가능하게 하였다. 결국 본 논문은 일러스트레이터의 사용자 인터페이스를 통하여 벡터 기반 캐리커처에 얼굴 모션 데이터를 적용한 캐리커처 얼굴 표정 애니메이션 생성이 가능하도록 하였다.

  • The esthetic factor for the esthetic prosthesis were studied on 300 persons. The praaticipants were 150 students registered under the Deparment of Dental Laboratoy Technology, Jisan Junior College at the present day of June, 1995 and their mothers. The results were as follows; 1. The number of persons with 28 teeth in their oralcatity was highest(P<0.01). They complained that they have only 28 teeth bacaues of the loss(deficiency) fo teeth due to their impacted teeth and dental caries. 2. The presons with feelings of dissatisfaction were large in number(P<0.01). They were dissatisfied with an abnormal tooth form(33.5%), tooth position(31.7%), tooth color(31.1%), and tooth size(3.7%) in order(P<0.01). 3. In their facial form, the most numerous were men with square form and women with ovoid form(P<0.01). Among the whloe number fo facial forms it appeared to decresae in the order of ovoied(41.8%), square(32.7%), square+tapered(20.5%), and tapered form(5%)(P<0.01). In a profile form, the most numerous were men with A form and women with B. Among the whole participants the most numerous were persons with B form and persons with A and C form were next in oder of numbers(P<0.01). 4. In discoloration of teeth, the most numerous were persons who have no discoloration. 5. In the esthetic recovery of anterior prosthesis the color matching of proximal teeth was not correct, but the outline of proximal teeth was to be reproduced correctly. 6. In the diastema of teeth, the number of persons who have no diastema was higher than that of persons who have a disatema(P<0.01) Among the persons who have diastema the most numerous were persons who have a diastema, and next were 2, 4, 3 and 5 diastemas in order. 7. In a meeting point of the midline of the body and the tooth the number of person hanving a meeting point was higher than that of persons who did not fit each other(P<0.01). The bias direction of midline teeth appeared to be affected by chewing direction, prosthesis location, and posterior location. 8. The length and width of teeth in the tooth size were suitable(P<0.01). The number of persons who have central teeth longer than lateral teeth was high(P<0.0). 9. In the results of smile analysis, the line form connected with incisal edge of upper canine were parallel(P<0.01). When smile the location fo upper lips should be in accord with the central area of teeth(P<0.01) and lower lip should be atteched to the edge of anterior teeth in order to be esthetic. 10. Among the number of upper teeth we can see the most numerous were 8 teeth and next were 10, 6 and 12 in order.

  • Oral cancer treatment involves the surgical removal of all or part of the maxilla, leaving the patient with a defect that compromises the integrity and function of the oral cavity. The postoperative restoration of esthetics, deglutition, and speech shortens recovery time in the hospital and expedites the patient's return to the community as a functioning member. The surgical obturator is the proven treatment option in such situations. This article describes a simple technique to fabricate a surgical obturator that restores patient's original dentition and facial and palatal tissue form. The obturator fabricated with this technique utilizes the vacuum formed index of patient's original tissue form and duplicated partly in heat and partly in auto polymerizing acrylic resin. Duplication of the original tissue form helps patient to minimize the immense physiological trauma immediately after the surgical resection. The obturator fabricated with this technique supports soft tissues after surgery and minimizes scar contracture and disfigurement, and thus may have a positive effect on the patients' psychology.
