Background: Squamous cell carcinoma (SCC) is the most commonly occurring malignant tumor in the oral cavity. In South Korea, it occurs most frequently in the mandible, tongue, maxilla, buccal mucosa, other areas of the oral cavity, and lips. Radial forearm free flap (RFFF) is the most widely used reconstruction method for the buccal mucosal defect. The scar of the forearm donor, however, is highly visible and unsightly, and a secondary surgical site is needed when such technique is applied. For these reasons, buccal fat pad (BFP) flap has been commonly used for closing post-surgical excision sites since the recent decades because of its reliability, ease of harvest, and low complication rate. Case presentation: In the case reported herein, BFP flap was used to reconstruct a cheek mucosal defect after excision. The defect was completely covered by the BFP flap, without any complications. Conclusion: Discussed herein is the usefulness of BFP flap for the repair of the cheek mucosal defect. Also, further studies are needed to determine the possibility of using BFP flap when the defect is deep, and the maximum volume that can be harvested considering the changes in volume with age.

Objectives: The objective of this study was to highlight the role of lateral arthroplasty along with interposition of the buccal fat pad (BFP) in the management of Sawhney type III temporomandibular joint (TMJ) ankylosis. Materials and Methods: Ten patients with TMJ ankylosis (7 unilateral and 3 bilateral, total of 13 joints) were treated with lateral arthroplasty and BFP interposition. The bony bridge of the ankylotic mass on the lateral aspect was resected, leaving a distance of 1.5 to 2.0 cm from the base of the skull to the neck of the condyle. The condyle was left intact. Coronoidectomy was performed on the ipsilateral side via the same approach in all cases. The inter-incisal opening was measured at that time, and if it was less than 35 mm, contralateral coronoidectomy was performed by using the intra-oral approach. After satisfactory inter-incisal mouth opening (${\geq}35mm$) was achieved, the TMJ surgical site was revisited, and BFP was retrieved and used to cover the lateral aspect of the medially placed condyle. Results: With lateral arthroplasty, the medially displaced condyle can be left in-situ to maintain the mandibular ramal height and function and to act as a growth center in children. Interposition of the BFP prevents reformation of the lateral bony bridge that was removed. Conclusion: Lateral arthroplasty along with interpositioning of the BFP is a novel technique for managing Sawhney type III ankylosis that achieves management goals while avoiding complex and advanced reconstructive surgical procedures.

To assess the deterioration condition of stator insulation, diagnostic and AC dielectric strength tests were performed on five high voltage (HV) motors (2,000 HP, 6.6 kV) for boiler feed-water pump (BFP). Two HV motors for BFP were installed per unit. Following the long term rewinding program, the diagnostic test was performed on five 6.6 kV motors during the planning maintenance period. After completing diagnostic test, AC dielectric strength test was done on the stator windings of HV motors. The AC dielectric strength test was conducted at 15 kV for one minute. Dielectric strength test and diagnostics test results confirmed that the stator insulation was judged to be in serviceable condition in the five 6.6 kV motors.

Many congenital and acquired defects occur in the maxillofacial area. The buccal fat pad flap (BFP) is a simple and reliable flap for the treatment of many of these defects because of its rich blood supply and location, which is close to the location of various intraoral defects. In this article, we have reviewed BFP and the associated anatomical background, surgical techniques, and clinical applications. The surgical procedure is simple and has shown a high success rate in various clinical applications (approximately 90%), including the closure of oroantral fistula, correction of congenital defect, treatment of jaw bone necrosis, and reconstruction of tumor defects. The control of etiologic factors, size of defect, anatomical location of defect, and general condition of patient could influence the prognosis after grafting. In conclusion, BFP is a reliable flap that can be applied to various clinical situations.

Objectives : The purpose of this study were to evaluate the effects of oriental medical therapy on obesity and different effects according to Body Mass Index(BMI), menopause, obesity treatment experience, age, treatment period in patients. Methods : 46 patients were treated from November 2011 to April 2012 in Oriental Obesity Center, Dong-eui Medical Center. They were measured change of body compositions by bioelectrical impedance analysis every 2~3 weeks and 27 patients out of 46 were checked body compositions every 2 weeks. 46 and 27 patients were divided into two or three groups according to BMI, menopause, obesity treatment experience, age, treatment period. We compared before and after treatment body compositions. Results : Body compositions, except edema index were significantly reduced. Abdominal Visceral Fat(AVF) was significantly reduced in Obese group. Body Weight(BW), BMI, Body Fat(BF), Body Fat Percetage(BFP), Abdominal Visceral Fat Level(AVFL), Abdominal Visceral Fat(AVF), Abdominal Subcutaneous Fat(ASF) were significantly reduced in non-menopause group(43 female patients). But in 26 female patients out of 27, there were no significantly differences between groups in menopause. There were no significantly differences between groups in obesity treatment experience. But in 27 patients, BMI and AVF were significantly reduced in non-experience group and AVFL was significantly reduced in experience group. BW, BMI, BF, BFP, VAF, ASF were significantly reduced in younger age group. But in 27 patients, BW and Muscle were significantly reduced in younger age group. BMI, BF, BFP, Edema, AFVL, Abdominal Visceral Fat Area(AVFA), AVF, ASF were significantly reduced in longer treatment period group. Conclusion : The BF, BMI, BF, BFP, Muscle, AVFL, AVFA, AVF, ASF were almost decreased significantly. It resulted that the effects of oriental medical therapy in obesity was positive. And it was meaningful study to know about different effects between groups.

The purpose of this study was to inform teachers or researchers relating teaching boys and girls of basic data for valid obesity education. The researcher collected 10 students(5 boys and 5 girls) and measured skinfold thickness and body-fat-percentile(% body fat) on 3 parts of the body every month during a year. The researcher checked the spring(March), summer(July), autumn(October) and winter(January) data consecutively and tried to answer the question that which season especially need the preventive education of obesity. The result as followed ; 1. The skinfold and BFP in summer were more bigger than those in winter but these differences were not significant. 2. Girls have a propensity to get higher skinfold and BFP than boys but these differences were not significant neither. Briefly speaking, in 12 months, the skinfold and BFP(compared in summer) in winter season has the highest and it showed that it was necessary to teach students to preserve their appropriate body fat through diverse activities. The researcher expects successive studies for much more students and by type of students are executed for supporting these results.

Mucoepidermoid carcinoma (MEC) is the most common type of malignant neoplasm in the minor salivary gland. The hard palate is a frequently involved site of MEC. The treatment of low-grade MEC on the hard palate is wide local resection with a tumor-free margin. In the present case, the maxillary defect was reconstructed using a buccal fat pad (BFP) flap, followed by application of 4-hexylresorcinol (4HR) ointment for 2 weeks. The grafted BFP successfully covered the tumor resection defect without tension and demonstrated complete re-epithelialization without any complications.

This work introduces a novel unweighted combination method (UCSS) for business failure perdition (BFP). With considering features of BFP in the age of big data, UCSS integrates the quantitative and qualitative analysis by utilizing soft set theory (SS). We adopt the conventional expert system (ES) as the basic qualitative classifier, the logistic regression model (LR) and the support vector machine (SVM) as basic quantitative classifiers. Unlike other traditional combination methods, we employ soft set theory to integrate the results of each basic classifier without weighting. In this way, UCSS inherits the advantages of ES, LR, SVM, and SS. To verify the performance of UCSS, it is applied to real datasets. We adopt ES, LR, SVM, combination models utilizing the equal weight approach (CMEW), neural network algorithm (CMNN), rough set and D-S evidence theory (CMRD), and the receiver operating characteristic curve (ROC) and SS (CFBSS) as benchmarks. The superior performance of UCSS has been verified by the empirical experiments.

Now a days, immediate implant placement: is becoming one of the popular method. But for the success of this method in implant surgery, initial stability and establishment of sufficient blood supply to the implant placement: areas are very important. Buccal Fat Pad(BFP) has favorable characteristics for the reconstruction of maxillary hard &soft tissue defects. So it has been used for reconstruction of posterior maxillary area or closure of oro-antral area. Using BFP, we could get primary tissue closure without extensive releasing incision during implant surgery and adequate attached gingival after healing of the surgical area. So We report clinical usefulness of BFG during immediate important placement in the posterior maxillary area
