N/A In order to observe the repair of injured peripheral nerve, various injuries were inflicted on the infraorbital nerves [ION] of Korean rabbits. Under the general anesthesia with 1% pentotal sodium, 25mg/kg, all animals were prepared surgically and devided into four groups by patterns of injury. They were as follows; Group 1: Crushing the ION with, hemostatic forceps. Group 2: Sharp cutting the ION with surgical scalpels. Group 3: Cutting the ION with electrode of electrosurgery. Group 4: Resection of the ION about 3mm with surgical fine scissors. Each groups were observed at the 1st, 4th, and 8th week after injury under the light microscope. Their results were w follows, At the 1st week after injury, severe Wallerian degeneration were seen in the all nerve tissues inflicted by various injuries, especially in the resection injured group. As time went by, the severity of degeneration was gradually reduced in all groups. 2. In all groups, proliferation of Schwann cells and fibroblasts occurred at the 1st week and was more conspicuous at the 4th week. Whereas regenerative nerve fasciculi were observed in the distal area at the 4th week and increased in their number and size at the 8th week. An attempt to regeneration of nerve was shown in all groups. 3. Collagenous materials were shown in the all groups but meager in the crushing group, compared with the transection or resection injured groups. 4. Recovery of anatomical morphology of nerves was more or less good in the crushing injured group but the transection and resection injured groups assumed the morphological picture of traumatic neuroma in that they consisted of proximal cellular area where the cells were arranged haphazardly and distal area where regenerative nerve fasciculi were the dominant structures.

본 연구는 금융 · 보험업으로서 2011년부터 2013년에 걸쳐서 본 연구의 표본 선정기준을 만족하는 기업을 대상으로 포괄손익계산서에 공시된 당기순이익과 총포괄이익의 기업가치 관련성의 상대적 중요성, 당기순이익에 대한 기타포괄이익의 추가적 설명력, 기타포괄이익의 개별항목별 기업가치 관련성을 Tobin Q 모델을 이용하여 검증하였으며, 검증결과를 요약하면 아래와 같다. ① 기업가치를 설명함에 있어서 포괄손익계산서에 공시된 당기순이익과 총포괄이익 간에 유의한 차이가 없는 것으로 나타났다. ② 산업 요인을 통제한 후에도 포괄손익계산서에 공시된 당기순이익과 총포괄이익 간에 유의한 차이가 없는 것으로 나타났다. ③ 기타포괄이익은 당기순이익에 추가적 설명력을 가지는 것으로 나타났다. ④ 기타포괄이익의 개별항목들 중에서 매도가능금융자산평가손익, 해외사업 환산손익, 현금 흐름위험회피파생상품평가손익, 확정급여제도보험수리적손익, 등의 항목이 기업가치평가에 양(+)의 영향을 미치는 것으로 나타났으며, 특별계정기타포괄손익과 기타포괄손익의 기타항목(유형자산재평가이익, 관계기업평가손익) 등은 기업가치평가에 유의한 영향을 미치지 않는 것으로 나타났다. The purpose of this study is to verify the correlation between the equity values of those financial and insurance companies listed on Korea Exchange and their other comprehensive incomes(losses). Empirical verification models expanded from the Ohlson’s equity valuation model(1995) which exchange the dependent variable of Ohlson model as Tobin’s Q as were used as verification models for this study. The results verified through this study can be summarized as follows: ① We found no significant difference between net income and total comprehensive income recorded on statement of comprehensive income in terms of their correlation with equity value. ② With certain industrial factors controlled, We found no significant difference between net income and total comprehensive income recorded on statement of comprehensive income. ③ We found an additional explanatory power of other comprehensive income on the net income. ④ The following items in other comprehensive income were found to have positive effects on equity value: Available for sale financial asset valuation gain(loss), overseas business translation gain (loss), cash flow hedging derivatives valuation gain(loss), defined benefit plan actuarial gain(loss), and so forth. In addition, the following items in other comprehensive income were found to have positive on equity value, but not significant at 0.1 level : special accounts’ other comprehensive income(loss), other items of other comprehensive income[asset revaluation gain(loss), Share of other comprehensive income of associates and joint ventures accounted for using equity method], and so on.

This is a case report of adenoid cystic carcinoma occurred in the right buccal mucosa near the orifice of Stensen s duct. The patient, 50 years-old female was admitted to Dept. of Oral & Maxillofacial Surgery, Chunnam University Hospital with the complaint of painless abnormal swelling in the right buccal mucosa area. The radical excision and irradiation therapy were performed. The summary and results are as follows; 1. The primary site of adenoid cystic carcinoma was the right buccal mucosa which was known as rare common site of origin among minor salivary glands. 2. There were no evidence of neural or perineural invasion, destruction or erosion of the contiguous bone (ramus of the mandible or maxillary tuberosity), and also no evidence of metastasis to the lung or cervical lymph node. 3. Postoperative complications, such as facial deformity, paralysis of right buccal cheek area, paresthesia of the upper lip and limitation of the mouth opening, were seen. 4. On the basis of clinical staging (Stage Ⅱ) and histopathologic grading (Grade Ⅰ), it seems that prognosis will be good but follow up over the years should be required.

본 교실에서는 가족력을 가지며, 하악에 다발성으로 재발된 치성각화낭종의 증례가 있어 보고하는 바이다. 환자들은 한 가족의 어머니와 두 자녀였으며 그중 어머니와 딸의 경우 낭종적출후 수차례의 재발을 보여 딸은 앞으로도 수술을 예정하고 있다. 낭종이외의 다른 기저세포모반증후군의 증거는 보이지 않았다. 처치로서 어머니와 딸의 경우 낭종적출술을 시행하였고 아들의 경우 낭종적출후 결손부의 크기가 커서 동종골이식을 시행하였다. 현재 어머니와 아들의 경우 재발은 보이지 않고 있으나 향후 지속적인 구강검사를 통해 관리예정이며 유전학적인 검사도 고려하고 있다. A family is presented in which multiple odontogenic keratocysts have been expressed. 3 members of the two generations of family with features of multiple keratocysts, suspected basal cell nevus syndrome have been investigated. The proband, 19-year-old woman and her mother, and her brother suffered from these cysts and two female patients' disease have been recurred multiply though careful treatments. Close attention to the family and routine follow up will alert the clinician to its recurrences and genetic counseling and serial screening for the development of other symptoms, that is malignant skin carcinoma etc.

This is a report of plunging ranulas originated from sublingual glands in 22 & 16 year old patients treated by removal of cystic lesion and sublingual or submandibular gland. In the case 2 of the removal sublingual gland, results of surgery was satisfied, in contrast to that, the recurrence of the ranula occured in the case 1, after the submandibular but not the sublingual gland had been removed. The results were as follows 1) plunging ranulas which involved the neck area must be differentiated clinically & histomorphologically from the other soft tissue lesions. 2) plunging ranulas were easily diagnosed with simple radiography used by contrast media. 3) plunging ranulas were mostly originated from the sublingual glands. 4) surgical treatment of the plunging ranulas was involved the removal of the originated sublingual glands Br cystic lesions.

Case reports and review of the surgical management of zygomatic complex fracture are presented. For open reduction and direct wire fixation, both conventional approach (combined supraorbital and infraorbital approach) and temporal flap approach were applied simultaneously to each patient. As a result, we could recognized that surgical management of zygomatic complex fracture through temporal flap approach could lead to much benifits, compared with the conventional approach, Although temporal flap approach may cause extensive soft tissue injury and greater disturbance of blood flow, compared with other routine surgical approach, it can provide the necessary exposure to perform meticulous and accurate operation while eliminating surgical risk to the facia1 nerve and also produce a cosmetically acceptable scar.

This is to report four cases of autogenous corticocancellous iliac bone graft for reconstruction of mandibular defects occurred by traumatic comminuted fractures and surgical removal of ameloblastoma. In only one case, infection developed shortly with suppuration on the 7th postoperative day and was well treated with adequate antibiotic therapy and drainage. In all cases, pain and paresthesia on donor site were complained but disappeared within a few days. All cases were satisfactorily treated with proper masticatory function and esthetic improvement.
