The purposes of this study were to segment consumers by Korean image perceptions and to investigate the differences among the segmented groups in regard to Korean image preferences in casual wear The subjects of the study were 653 women consumers who lived in Seoul. Data were collected from July to September, 2007. Statistical analyses used in the study were factor analysis, cluster analysis, ANOVA, and Duncan test. The results showed that there were four factors of Korean image perceptions: natural, feminine, passionate, and simple images. Based on the four factors, the consumers were segmented into three groups. They were natural image perception group, low interest group, and feminine image perception group. The results showed that there were significant differences among the segmented groups in regard to Korean image preferences In casual wear. For example, natural image perception group prefer diverse Korean prints, blue and green colors, natural fabrics, and diverse casual types for their Korean image casual wear. In the meanwhile, feminine image perception group generally prefer soft fabrics, red and purple colors in their Korean image casual wear.

First of all a good surgical access is considered among various approach methods to the cystic lesion. A poor surgical access can lead to a failure of the whole treatment. A sagittal split ramus osteotomy (SSRO) on the large cyst occurring in the mandibular ramus lets us not only reduce operation time, but can additionally contribute to a good visual field. In addition, a merit exists that it lets this operating method provide soft tissue adhesion for proximal and distal segment and decrease post operative necrosis. We experienced three cases of a large cyst on the mandibular angle and ramus. By employing a sagittal splitting of the mandible, it provided good surgical access and operation results without recurrence during a follow-up period. The surgical technique described may be helpful in treating similar large cysts.

Primary hemangioperiycytoma is quite rare tumor of the lung and arising from pericyte in external layer of capillaries. Most cases are developed in 4th and 5th decade, are asymptomatic, and have malignant otential. On chest radiography, primary pulmonary hemangiopericytoma shows lobulated, well demarcated, homogeneous soft tissue density. Microscopically, it consisits of numerous vascular spaces of variable size and shape separated by aggregates of tightly packed oval to spindle-shaped cells. Treatment of choice is surgical excision. We report a case of primary pulmonary hemangiopericytoma in a 16-year-old man who had well demarcated homogeneous mass in the superior segment of left lower lobe, but had no symptom. He had undergone left lower lobectomy. He has been followed up for 8 months but has no sign of relapse or metastasis yet.

For the successful placement of dental implants, adequate alveolar bone height and width are required. Alveolar distraction osteogenesis is an effective method that resolves insufficient alveolar bone height for dental implant placement, and thus has been clinically applied with satisfactory results. But, minor and major problems may occur during the treatment. In the following report, we studied for such problematic cases. The problems are as follows: 1) sharp edges of the transport segment, 2) infection, 3) soft tissue dehiscence, 4) limitation of distraction, 5) numbness, 6) insufficient bone formation. But, most of them were answered by simple solutions and did not jeopardize the final outcomes. Distraction osteogenesis can be considered a safe and predictable procedure for lengthening the alveolar bone.

Background: To introduce a novel technique for advancement genioplasty helping surgeons to avoid soft tissue difficulties especially in short-faced patients with deep mentolabial fold and everted lower lip. Case presentation: In a trapezius-shaped, osteotomy was performed in the chin region. The mobilized segment was advanced, and the existing gap was grafted using interpositional allograft materials. Each side had been fixated by three-hole plates and two screws. The outcomes revealed no change in lower anterior teeth vitality. The patients did not report any changes of sensation in lower lip and chin either. The measurements indicated no increase in depth of mentolabial fold in patients undergoing this surgical technique. The postoperative evaluation showed a successful esthetic outcome for the patient and the surgeon concurrently. Conclusion: Based on our experience, the authors concluded that the Balcony technique is a simple and reliable procedure for patients with a deep mentolabial fold.

Rhabdomyosarcoma is a rare malignancy of head and neck region. When rhabdomyosarcoma occurs in maxillary area, total maxillectomy is necessary. Total maxillectomy causes defects of orbital floor, palate, gingiva, and alveolar bone, causing severe facial deformity and functional impairment. Immediate maxillary reconstruction has to cover both bone and soft tissue to minimize cosmetic and functional problems. The fibular osteocutaneous free flap can provide paranasal, gingiva, oral mucosal lining and foundation for dental prosthesis, thus ensuring good cosmetic results and mastication, phonation function. We have experienced a reconstruction case of a 19-year-old man with rhabdomyosarcoma of the left maxillary sinus. The patient underwent total maxillectomy and neck dissection. We designed a fibular free flap that had a vascularized bone segment and a double skin paddle. Surgical outcomes were excellent in cosmetic and functional aspects.

We experienced a case of primary sternal tuberculosis with destroyed midsternum and bony defect. An 22-year-old female was admitted to our hospital two times for severe sternal pain and spontaneous fracture without history of trauma. On hospital admission, chest X-ray and chest CT showed destruction of midsternum and soft tissue swelling. Fine needle aspiration cytology revealed tuberculous osteomyelitis with cold abscess. And the patient was treated with usual anti-tubeculosis medication for preoperative preparation. At operation, we confirmed midsternal destruction with cold abscess and multiple sinus tracts. After removal of diseased sternal segment and cold abscess, we performed sternal reconstruction with autologus iliac bone graft. The pathologic report was compatible with tuberculous osteomyelitis and caseous necrosis The postoperative course was smooth and uneventful, and she remains well without sternal instability two months later.

A 7-year-old castrated male Schnauzer was presented with melena and inappetence. Laboratory examination revealed mild anemia. Abdominal ultrasonography showed abnormal enlargement of intestinal segment and a oval mass with soft tissue density. After surgical resection of the enlarged intestine including the mass, histopathologic examination showed that the mass was tentatively diagnosed as synchronous occurrence of gland cell- and mesenchymal cell-origin tumors. Subsequently, immunohistochemistry showed positivity to cytokeratin AE1/AE3 in the gland cells and positivity to ${\alpha}-smooth$ muscle-specific actin, but negative expression of c-Kit, suggesting the co-existence of adenocarcinoma and leiomyosarcoma. Follow-up examination after 3-year of the surgery confirmed that the dog remained healthy and did not show recurrence of the tumors.

Waterborne polyurethanes(WPU) based on castor oil were successfully prepared using polycaprolactone diol(PCL), castor oil(CO) and 4,4'-methylene dicyclohexyl diisocyanate($H_{12}MDI$) as soft segment part, dimethylolbutanoic acid (DMBA) as emulsifier, and trimethylamine(TEA) as neutralizer based on different molecular weight of prepolymer. The various properties such as mechanical strength and surface reforming were evaluated using UTM, contact angle, FE-SEM based on the different molecular weight of polyol. Waterborne polyurethanes based on castor oil could be considered as a promising candidate to be applied the various adhesion fields.

In this work, the thermoplastic polyurethane (TPU) was melt-blended with EPDM, NBR and BR to form TPU/Rubber blend films, their composition and friction-induced surface fracture relationship was investigated. TPU/EPDM and TPU/BR blends exhibited the improved friction-induced surface fracture, especially the effect of BR was excellent. With addition of more than 10 wt% BR, TPU/BR blends exhibited the improved friction-induced surface fracture. The increase of the soft segment with increasing BR content, which was confirmed by scanning electron microscopy (SEM) analysis enabled us to estimate the improved friction-induced surface fracture.
