고재찬,이범철,김봉수,최은창,Koh, Jae-Chan,Lee, Bhum-Cheol,Kim, Bong-Soo,Choi, Eun-Chang 대한전자공학회 2001 電子工學會論文誌-TC (Telecommunications) Vol.38 No.8
본 논문에서는 전송 분야 뿐만 아니라 interconnection 분야에서 사용할 수 있는 새로운 선로 부호를 제안한다. 제안된 선로 부호는 1 비트의 잉여(redundancy) 비트를 사용하면서도 선로 부호가 갖는 기본적인 특징을 보장하며, interconnection 분야에서 필요한 byte 또는 frame 동기를 위한 직렬 동기 패턴 제공, 특수 문자 또는 in-band signaling을 제공한다. 8비트 이상의 병렬 데이터를 부호화 하거나 직렬 비트 스트림(steam)으로 전송하기 쉽게 하여 주는 제안된 NIBI 부호 생성 알고리즘, 복호 알고리즘 및 부호 성능에 대해서 기술한다. This paper describes new line code algorithm, called NIDI(Nibble Inversion mock Inversion) which is well suited for interconnection and transmission technology, The proposed line code which includes only one redundancy bit serves primary features of line code and synchronization patterns for byte or frame synchronization in interconnection, Also, this line code provides in-band signals and speciaI characters.

Head and neck arteriovenous malformation usually forms huge mass, cause profuse bleeding or potenially compromise the airway. This bleeding is vulnerable to be uncontrollable and lifethreatening. Sometimes it has a high mortality. Although surgical resection is possible in some cases, the morbidity such as a defects of soft tissue is very high and its reconstruction is very difficult. The authors report an 11 year old female patient in whom occlusion of arteriovenous malformation with glue after transcutaneous embolization made a satisfactory results. At the beginning, she was transferred for massive oral bleeding. The bleeding was persistent and it was not possible to remove the packing in spite of many times of embolizations through feeding arteries. The massive bleeding trom the left upper alveolar mucosa compromised the airway and tracheotomy was done. Whenever the hypovolemic shock was occurred in a short time, blood transfusion and cardiopulmonary resucitation were done. To embolize the vascular mass of arteriovenous malformation, as a final trial before operation, the spinal needle was administered through the left upper gingiva under the fluoroscopy. The glue was injected on the target. The bleeding was stopped and we have noticed the absence of nidus on follow-up angiography after 3 weeks. We experienced that some cases of arteriovenous malformation in head & neck revealing the bleeding could be treated with transcutaneous embolization instead of surgical resection.

Purpose: Submandibular gland tumor is rare, less than 6% of head and neck tumor. The purpose of this article is to analysis the clinical experience and treatment outcomes of malignant submandibular gland tumor, suggesting a guideline of management. Methods: We retrospectively evaluated 26 patients who underwent operation for malignant submandibular gland tumor at Severence hospital between 1986 and 2004. Statistical analysis was performed by Kaplan-Meier method, log rank test, Chi-square test, Fisher's exact test using SPSS v12.0 for Windows. Results: They consisted of 18 males and 8 females whose median age was 47 years(range: 20-71). 10 cases of adenocystic carcinoma, 8 cases of carcinoma ex pleomorphic adenoma, 4 cases of mucoepidermoid carcinoma, 1 case each for acinic cell carcinoma, undifferentiated carcinoma, adeno carcinoma, epithelioid hemangioendothelioma. Sialoadenectomy only was performed in 10 cases(36.5%) and sialoadenectomy with neck node dissection was performed in 16 cases(63.5%). Adjuvant radiotherapy was done in 22 cases(84.6%). 10 year disease free survival rate for malignant submandibular gland tumor was 63.1 % and 10 year overall survival rate for malignant submandibular gland tumor was 70.1%. In univariate analysis, prognostic factors affecting recurrence of malignant submandibular gland tumor was initially papable lateral neck node in physical examination and metastasis of lateral neck node in pathologic confirmation. The prognostic factors affecting survival of malignant submandibular gland tumor was tumor size, TNM stage, recurrence and type of recurrence. Conclusion: In this study, prognostic factors affecting recurrence of malignant submandibular gland tumor was initially papable lateral neck node in physical examination and metastasis of lateral neck node in pathologic confirmation. The prognostic factors affecting survival of malignant submandibular gland tumor was tumor size, TNM stage, recurrence and type of recurrence. To prevent recurrence and to improve survival, early diagnosis and aggressive surgery must be considered.
