The ear cartilage that is classified as elastic cartilage is different from others in anatomic and clinical situation, and it is invaluable to study on wound repair of the ear cartilage and its external appearance. Concerning wound repair of the cartilage, many studies had directed to the wound repair of the articular cartilage an its application. However, some random studies in cauliflower ear deformity and cartilage transplantation had been reported regarding the ear cartilage until 1972, when skoog & coworkers revealed the perichondrial potential for cartilage regeneration. since them, many reports about the cartilage studies had been published. In order to clarify the better appearance of the ear after the certain surgical repair of the ear cartilage, this study was carried out using rabbit's ear as the experimental animal as follows: A different surgical wounds were created in each ear and repaired in different way respectively, first group created about 0.5cm×1.5cm of cartilage defect with its perichondrium and overlying skin closure, second group created the same sized cartilage defect leaving perichondrium intact and overlying skin closure, third group created the cartilage gap with its perichondrium and gap closure by overlapping edges, and forth group created gap closure by edge-to-edge approximation with figure of eight suture. On the 3rd, 6th, 12th, 24th, 30th, and 42nd days following surgery, the gross appearance of the each ear as well as the histologic findings of the cartilages were observed, and the results were summerized. 1) Marked ear bulkiness (thickening) was shown in the group 3, and normal to least thinning of the ear was shown in group 1 and 2, But in group 4, smooth appearance of the ear without change in thickness was observed. 2) In all groups, the primitive mesenchymal cells and fibroblasts were aggregated in early period of the healing process and decreased in number gradually changing to the loose connective tissue in 12th post-surgical day. The inward growing of the immature chondrocytes from the porichondrium to the cartilage side was observed in 24th post-surgical day, particularly in group 2 and come degree at the cut edge of cartilage in other groups. 3) In conclusion, it may be indicated that the regeneration of the cartilage is originated from the perichondrium in the defect of cartilage, and eage-to-edge approximation with intact perichondrium is the best method to attain the original gross appearance of the ear.
소비경험의 의례화에 영향을 미치는 요인에 관한 연구 : 의례적 기대성과를 중심으로 A Focus on the Expected Ritual Performances

Recently, consumer researchers have been interested in consumption ritual that expressed condensedly the consumption system in a culture. In this study, the factors of ritualization in clothing behavior were tested through a questionnaire survey to 434 Korean housewives. The social expecting benefits of clothes grooming ritual have influences on the internal ritualization of dressing behavior and the individual expecting benefits of clothes grooming ritual have influences on the external ritualization of dressing behavior. To ritualize the consumption experience, it is important for markters to develop promotion messages which emphasize expected benefits of ritual behavior.
