The mandibuloplasty for the facial aesthetic reason has been the one of the most popular procedures in aesthetic facial bone surgery in East Asia. Most East Asian women prefer smaller-looking and smooth-shaped facial contour. Prominent mandible angle which are common in Asia would be the main problem for smooth facial contour. In addition, recently, the mandibular body and broad chin shape also are known to be remodeled in order to get the ideal smooth facial shape. However, mandibuloplasty is not that easy to cut because many patients has inward mandibular angle and the visual field in operation is limited. The aim of this trial is to try to provide the prefabricated cutting guide for the symmetric and appropriate mandibuloplasty with the surgeons. Preoperative computed tomography(CT) data were processed for the patient and computer simulation model was produced. Then, mandibuloplasty was done on the computer simulation screen. Based on this data, customized cutting guide was made. This prefabricated cutting guide was used in real mandibuloplasty bilaterally. Premade cutting guide for the mandibuloplasty based on the computer simulation turned out to be very successful in this patient. Individualized approach for each patient could be an ideal way to manage the patients in near future.

When making crown and bridges on anterior regions, many practitioners consider the esthetics the most. For this reason functional aspect are not considered as much as the esthetics. If the occlusion on the anterior region are not formed correctly, movement of the temporomandibular joint can be disturbed and excessive stress can be occur that pathologic condition can be under lied. On this case presentation will show the importance of the anterior guidance and suggest the appropriate protocol of using customized anterior guide table. A 45years old male had to remake both of the upper central and lateral PFM because of the porcelain fracture. The new PFM crowns were made conventional methods without considering the anterior guidance. After the temporary setting, the patient complained of discomfort and short looking upper anteriors. To solve these problems we had to restore the palatal contour and length of the new crowns by making customized anterior guide table using temporary crowns that contains patient's old anterior guidance. This procedure which is copying the pt's comfortable anterior guidance to the final prosthesis made them to be esthetic and patients to feel comfortable.

This study was aimed at giving help to the people intending to change hair fashion feeling for making their own hair style design and also providing the academic guide line to the cosmetic circles for developing new hair design and promoting sales by producing hair styles following the results from the statistical analysis based on the theoretical study on the face contour groups & hair fashion feeling groups. The researching methods were composed of following 3 steps ; prior theoretical research, statistical analysis, and hair style production. At first, the prior theoretical research was accomplished by analysis of literatures, magazines and internet sites about face contour, total & hair fashion feelings, hair style productions. Second, the prior statistical analysis were done about hairstyle images & their charateristics based on fashion feelings, and characteristics of fashion feeling group. And the third, hair style productions were done coordinated by face contours(oval, circle, long, square, reverse triangle) and hair fashion feelings(natural, sexy, sophisticate, ethnic, romantic pretty, elegance, sporty, avant garde) following the statistical results. But owing to the limitations to change hair length and color, these changes are modified by wigs and photoshop 7.0 program. So we could know there was no confirmed hair fashion feeling of one's best, but one could change one's hair fashion feeling and express one's beauty if one could adjust one's hair styles properly to one's face contour. This study would be very helpful to the people trying to change their own hair fashion feeling and be useful to the cosmetic circles for developing new design and promoting sales by comprehending hair design market and also be valuable to develop the methodology of 3 step research.

The inventory maps of landslide deposits show where landsliding has occured in the past, and serve as a general guide to slope stability. Isopleth maps derived from those inventory maps, generalized and quantify the areal distribution of landslide deposits in contour form. Isopleth maps can provide an economical means for the recognition of landslide activity and assessing the degree of landslide hazard in a large area, especially rural areas. Isopleth maps of Bonggye area, where the degree of landslide hamedial efforts during the period of 1954-1971.

CXC chemokine receptor 2 (CXCR2) is a prominent chemokine receptor on neutrophils. The neutrophilic inflammation in the lung diseases is found to be largely regulated through CXCR2 receptor. Antagonist of CXCR2 may reduce the neutrophil chemotaxis and alter the inflammatory response. Hence, in the present study, ligand based Comparative molecular field analysis (CoMFA) was performed on a series of CXCR2 antagonist named pyrimidine-5-carbonitrile-6-alkyl derivatives. The optimum CoMFA model was obtained with statistically significant cross-validated coefficients ($q^2$) of 0.568 and conventional coefficients ($r^2$) of 0.975. The contour maps suggest the important structural modifications and this study can be used to guide the development of potent CXCR2 antagonist.

A new method for recognizing and locating partially occluded or overlapped two-dimensional objects regardless of their size, translation, and rotation, is presented. Dominant points approximating occuluding contoures of objects are generated by finding local maxima of smoothed k-cosine function, and then used to guide the contour segment matching procedure. Primitives between the dominant points are produced by projecting the local contours onto the line between the dominant points. Robust classification of primitives. Which is crucial for reliable partial shape matching, is performed using adaptive resonance theory (ART2). The matched primitives having similar scale factors and rotation angles are detected in the hough space to identify the presence of the given model in the object scene. Finally the translation vector is estimated by minimizing the mean squred error of the matched contur segment pairs. This model-based matching algorithm may be used in diveerse factory automation applications since models can be added or changed simply by training ART2 adaptively without modifying the matching algorithm.

Panfacial bone fracture is challenging. Even experienced surgeons find restoration of original facial architecture difficult because of the severe degree of fragmentation and loss of reference segments that could guide the start of facial reconstruction. To restore the facial contour, surgeons usually follow a general sequence for panfacial bone reduction. Among the sequences, the bottom-to-top and outside-in sequence is reported to be the most widely used in recent publications. However, a single sequence cannot be applied to all cases of panfacial fractures because of the variations in panfacial bone fracture patterns. In this article, we intend to find the reference and discuss the efficacy of inside-out sequence in facial bone fracture reconstruction.

To solve the problem of poor noise suppression capability and frequent loss of edge contour and detailed information in current fusion methods, an infrared and visible light image fusion method based on variational multiscale decomposition is proposed. Firstly, the fused images are separately processed through variational multiscale decomposition to obtain texture components and structural components. The method of guided filter is used to carry out the fusion of the texture components of the fused image. In the structural component fusion, a method is proposed to measure the fused weights with phase consistency, sharpness, and brightness comprehensive information. Finally, the texture components of the two images are fused. The structure components are added to obtain the final fused image. The experimental results show that the proposed method displays very good noise robustness, and it also helps realize better fusion quality.

Purpose: The buttocks region has been associated with allure and sex appeal for centuries. Gluteal implants enable buttocks remodeling in a way that is not possible in other methods. One of the reasons that render gluteal implant surgeries unpopular is the fear of complications, the main problems being seroma, wound dehiscence, extrusion, and a visible or palpable implant. The authors present the XYZ technique, which provides anatomical reference points to guide the intramuscular dissection procedure in a feasible and safe way, resulting in a lower complication rate. Methods: The XYZ procedure was done for buttock augmentation on 8 patients from December 2009 to June 2010. Patient's ages ranged from 27 to 44 with a mean age of 36. Seven patients were applied the 250cc sized Elastomer implants with one patient 290cc sized implant. Preoperative marking was done with the patients in the standing position. Bisection of the gluteus maximus muscle was done at the midpoint thickness to create a plane for implant insertion, which is called the sandwich plane. Results: The 8 cases were performed safely without major complications. However one patient had minor wound dehiscence, and was managed with conservative treatment. Another patient had a discomfort on the buttocks for a long time. The patients were followed up for average 6 months. All patients were satisfied with the aesthetic results. Conclusion: In performing the XYZ technique for gluteal augmentation, the surgeon must split the muscle into two equal halves with anatomical reference points to guide the muscle detachment in a symmetrical way at an adequate depth. This method provides a guideline for the surgeon in determining the ideal plane during intramuscular dissection and gives predictable results with low complication rates. Intramuscular gluteoplasty with gluteal implants offers predictable, aesthetically pleasing results without contour irregularities and only a low incidence of major complications.
