Treatment of the mandibular fracture consists of reduction and fixation. Primary wire & Arch bar are perhaps the ideal method for intermaxillary fixation. But, daily feeding, swallowing, speech, and in some instances, respiration is difficult to maintain during the period of intermaxillary fixation, owing to muscle weakness, emotional disorder and poor oral hygiene in a position of the long-term bed disabled patient with multiple injuries. Therefore, Intermaxillary fixation is not applied in the disabled bed patient, the alternative methods must be obtained. In the case of the mandibular fracture, because of the absence of weight bearing, osseous union may eventually occur even without immobilization if the patient is maintained without wound infection on a controlled soft diet. For the purpose of the prevention of the wound infection, the establishment of an drainage on the oral lacerated wound is necessary for the removal of the hematoma & seroma in the fracture site. This is the report of a case that was managed conservatively without the intermaxillary fixation in the long-term disabled bed patient with a mandibular compound fracture.

According to the Ministry of Health and Welfare, the portion of physical disability was 51.4% which was the highest among the registered disabled in December 2015, followed by visual disability(10.1%), disability of the brain lesions(10.0%), hearing disability(10.0%). The aim of this study is to investigate the types of disability in patients with disabilities visiting the Pediatric Dentistry, Chonbuk National University Dental Hospital in 2016. Of the patients who visited the pediatric dentistry, 196 patients (7.5%) had disabilities, and 19 patients had two or more disabilities. Twelve patients (6.1%) had both disabilities of brain lesion and intellectual disorder. Of the 177 patients with only one disability, 54 patients (30.5%) had physical disorders and 123 patients (69.4%) had psychiatric disorders. In psychiatric disorders, intellectual disorder was the most with 98 patients (55.3%), followed by autistic disorder with 23 patients (12.9%). In physical disorders, disability of brain lesion was the most with 37 patients (20.9%), followed by speech disability with 8 patients (4.5%). In this study, as a result of analyzing the types of disability with the patients who visited the Pediatric Dentistry of Chonbuk National University Dental Hospital, most of them had either intellectual disorder, disability of brain lesion, or autistic disorder. Dentists need to understand their general and dental characteristics to treat children and adolescents with disabilities. Since the most chief complaint of the patients was dental caries, early interventions should be made by dentist to reduce the incidence of the disease.

Background: Closed reduction is the standard treatment for nasal bone fractures, which are the most common type of facial bone fractures. We investigated the effect of closed reduction on quality of life. Methods: The 15-dimensional health-related quality of life survey was administered to 120 patients who underwent closed reduction under general anesthesia for nasal bone fractures from February 2018 to December 2019, on both the day after surgery and 3 months after surgery. Three months postoperatively, the presence or absence of five nasal symptoms (nose obstruction, snoring, pain, nasal secretions, and aesthetic dissatisfaction) was also evaluated. Results: The quality of life items that showed significant changes between immediately after surgery and 3 months postoperatively were breathing, sleeping, speech, excretion, and discomfort. Low scores were found at 3 months for breathing, sleeping, and distress. There were 31 patients (25.83%) with nose obstruction, 25 (20.83%) with snoring, 12 (10.00%), with pain, 11 (9.17%) with nasal secretions, and 29 (24.17%) with aesthetic dissatisfaction. Conclusion: Closed reduction affected patients' quality of life, although most aspects improved significantly after 3 months. However, it was not possible to rule out deterioration of quality of life due to complications and dissatisfaction after surgery.

Since environmental problems were globalized, discussions on 'Sustainable Development' started from Rio Declaration on Environment and Development(Rio Agenda 21). In Korea, the idea of 'Green Growth' was introduced and generalized since the celebration speech made on 8.15(Independence Day of South Korea) on 2008. And Low Carbon- Green Growth Basic Law was established on 2010. There are 3 strategies and 10 sub-tasks to achieve green country-traffic and green revolution of life. Family resource management is capable of changing life style from energy wasty to ecologically green. The value of family resource management plays a critical role in changing the lifestyle through influencing the goal and standard setting. So, this study is aimed to suggest the green value and green way of life from the perspective of family resource management. Results are as follow. First, the green value is to change from 'material-oriented' to 'people-oriented'. The 'material-oriented value pursues pleasure from possessing, but the 'people-oriented' value pursues pleasure from being itself. Second, the change from the value of 'human-mastery of the nature' to the value of 'mother -nature' is necessary. The value of 'human-mastery of the nature' seeks pleasure from the velocity and tangible outcome. But the value of 'mother- nature' seeks pleasure from the time to relax and slow way of life. 'Third, the change from the value of 'individualism' to the value of 'community sprit' is necessary. Individualism focuses on man's achievement, which may fall into family egoism. And the green way of life suggests the change from 'results-oriented' to 'enjoy the process itself", from 'consumption' to 'ecological restoration' and from 'work to home and then home to community'.

현대 사회에서 디지털 처리 기술은 다양한 분야에서 응용되고 있다. 대표적으로 음성 및 영상 처리에 관한 신호 처리 기술을 들 수 있으며, 이러한 신호 처리를 위한 필터는 크게 FIR 필터와 IIR 필터로 나눌 수 있다. FIR 필터는 IIR 필터에 비해 높은 차수로써 구현이 되어지는 단점이 있으나, 안정적이며 구현하기에 용이하다는 장점을 가진다. 또한 선형 위상 응답 특성을 가지고 있어, 파형 정보 특성이 중요시되는 곳에 사용되어지고 있다. FIR 필터 구현에 있어 주요한 문제점은 깁스현상을 최소화시키는 것이다. 따라서 본 논문에서는 변형된 창함수를 이용한 FIR 디지털 필터를 사용하여 기존에 제시된 방법과 비교하였다.

지난 수십 년 동안 인공 신경망은 음성 인식에서 이미지 분류에 이르기까지 수많은 분야에서 성공적으로 사용되었다. 그러나 인공 신경망은 특정 결론이 어떻게 도출되었는지 알 필요가 있음에도 불구하고 이러한 결과를 설명할 수 있는 능력이 부족하다. 대부분의 연구는 신경망에서 이진 규칙을 추출하는데 초점을 맞추고 있지만, 기계 학습 응용 프로그램에 사용되는 데이터는 연속된 값이 포함되어 있기 때문에 실용적이지 않은 경우가 있다. 이러한 격차를 줄이기 위해 본 논문에서는 연속된 값이 포함된 데이터로부터 학습된 신경망에서 논리 규칙을 추출하는 알고리즘을 제안한다. 초평면 기반 선형 분류기를 사용하여 입력 및 은닉 층 사이에서 학습된 가중치로부터 규칙을 추출하고, 비선형 분류 규칙을 생성하기 위해 은닉 층과 출력 층에서 학습된 이진 규칙과 분류기를 결합한다. 비선형 연속값으로 구성된 여러 데이터셋을 대상으로 진행한 실험에서 제안하는 방법이 논리적 규칙을 정확하게 추출할 수 있음을 보였다.

Purpose: The purpose of this study is to evaluate the functional outcome and donor site morbidity of anterolateral thigh free flap(ALT) compared to Radial forearm free flap(RFFF) for the reconstruction of partial glossectomy defect. Methods: 5 ALT free flap (group I) were attempted for partial glossectomy patients. We compared patients undergone ALT flap with those(n=11) of similar size defect reconstructed with RFFF (Group II). Rating scales for articulation and swallowing function were applied and donor site morbidity have been evaluated. Results: The scales for speech function showed no difference between the two groups (average score; group I - 6.4, group II - 6.45). Swallowing function also showed no difference between the two groups(average score; Group I - 6.6, Group II - 6.27). ALT group had one patient with donor site morbidity(numbness). All of the RFFF patients(11/11) complained and suffered from hypertrophic scar, retraction, numbness or hyperpigmentation on forearm donor site. Based on our study, ALT free flap is comparable to that of RFFF in terms of functional assessment in tongue reconstruction. Conclusion: Considering the donor site morbidity, ALT flap is to be valuable to reconstruct partial glossectomy defect.

Purpose: The primary goal of palatoplasty is to enable normal speech with harmonious growth of face. Some children who had palatoplasty display typical findings of transverse maxillary deficiency requiring orthodontic widening of the maxilla. Levi (2009) described a cleft palate repair coupled with pedicled buccal fat pad flaps to cover bone exposed areas of the hard palate. Hence we report clinical experiences of cleft palate repair using pedicled buccal fat pad flap. Methods: Four Veau class II and a Veau class I cleft palate patients underwent palatoplasty with buccal fat pad flap by single surgeon from April 2009 to August 2009. Two patients received 2-flap palatoplasty and three patients 1-flap palatoplasty, respectively. After the cleft palate repair, sharp mosquito scissors was placed in the superior buccal sulcus just lateral to the maxillary tuberosity and inserted directly through the mucosa resulting in buccal fat pad extrusion. The elevated flap was moved to cover mucoperiosteal defect in hard palatal area. Results: Five patients underwent primary palatoplasty using buccal fat pad flap. Flap harvest and inset took on average 9 minutes per flap. Mucosal epithelization took 18 days on average. No patients had complications related to the buccal fat pad flap. Conclusion: Buccal fat pad pedicled flap has significant potential to function as an added vascularized tissue layer in cleft palate repair and we can expect better growth of maxilla with this method although longer duration of follow-up was unavailable.
