Three species belonging to genera Acaphylla Keifer and Calacarus Keifer (Prostigmata: Eriophyidae) that cause damage to Camellia (Theaceae) plants, have been newly recorded in Korea. The three species, Acaphylla theae (Watt), Acaphylla theavagrans Kadono, and Calacarus carinatus (Green), have been redescribed and illustrated. Keys to Korean species of the genus Acaphylla; their distribution; and biological information, such as host plants and damage symptoms, are also presented.

In this research, 10x10 ㎠ unit cells were fabricated via liquid condensation process and uni-axial pressing followed by the screen printing of electrolyte and cathode layer. The SOFC stack was assembled with unit cells, gasket-type sealant and metal interconnect. The stack was designed to have a single column with internal-manifold and cross-flow type gas-channels. Stack was evaluated in terms of cell performance, electrical contacting, sealing, thermal stability and degradation. In addition, key issues in fabricating components and unit cell are addressed with respect to the performance optimization and microstructure development.

Various surgical technique have been used for the reconstruction of temporomandibular joint. During the past several years, conventional(nonvascularized) costochondral bone graft has been employed most successfully because of its anatomical similarity and functional capabilities of the condyle and costal cartilage. But the conventional costochondral bone graft has limitation in poor recipient site combined with large soft tissue and bone defect. With the advent of microsurgery, vascularized bone graft has proven invaluable. In this report of a case, we discuss the surgical technique and anatomy of free vascularized myoosteochondral rib graft. The result confirms that it is a successful and sound method for reconstruction of temporomandibular joint.

A Bednar tumor is a variant of dermatofibrosarcoma protuberans(DFSP). The clinical and histopathological findings of Bednar tumors are identical to DFSP except for the presence of melanin-containing cells scattered within the lesion, so called pigmented DFSP. The majority of Bednar tumors are seen as DFSP present as multinodular protuberant masses in the skin. They can also present as an atrophic depressed scar-like lesions without any nodularity. We report an uncommon clinical presented case of a Bednar tumor on the back in a 22-year-old female. She presented with an asymptomatic, firm, bluish, chestnut sized, depressed and atrophic lesion on the back which had been present for 6 years. A Histopathological examination revealed massive proliferation of spindle-shaped cells arranged in a tight storiform pattern mixed with scattered pigmented cells. On immunohistochemical staining, the tumor cells were positive for vimentin, a -l-antitrypsin, and CD34, but were negative for cytokeratin, neurofilament, and factor XIIIa. The majority of the tumor cells was negative and the pigment cells were positive for the S-100 protein. The patient was treated by a wide local excision of the lesion. There has been no evidence of recurrence after 20 months post-operative follow up. (Korean J Dermatol 1998;36(1): 139-142)

TMJ reconstruction is one of the most challenging surgical treatment, and many methods using autogenous and alloplastic materials have been reported for making neocondyle. Although alloplastic materials which include aclylic, synthetic and total joint system are recently widely used, many surgeons agree that autogenous TMJ reconstruction is gold standard until now. In this article, classification of the TMJ defects and the various TMJ reconstruction methods using autogenous source were introduced with review of literature.
브랜드 커뮤니티에서의 UCC를 통한 상호작용이 펌 행위 의도와 커뮤니티 방문충성도에 미치는 영향

최근 몇 년 동안 브랜드 커뮤니티에 대한 연구는 많은 반면에, UCC에 관련된 연구는 아직 미비한 실정이며, 또한 브랜드 커뮤니티에서의 UCC의 연구도 활발하게 진행되고 있지 못하다. 본 연구에서는 UCC를 하나의 새로운 현상으로 보는 것이 아니라 이러한 UCC가 브랜드커뮤니티에서 상호작용을 통해서 퍼뮤니케이션되는 현상을 학문적 연구를 통해 시사점을 제시하고 브랜드 커뮤니티에 관한 향후 연구의 방향을 제시하는데 목적이 있다. 이에 따라서 본 연구는 온라인 브랜드 커뮤니티에서의 UCC를 통한 상호작용이 펌 행위의도와 방문충성도에 미치는 영향에 대해 규명하고자 하였다. 연구결과를 살펴보면, 첫째, 브랜드 커뮤니티의 품질특성 중에서 정보성만이 모든 상호작용성에 정의 영향을 미치는 것을 알 수 있다. 둘째, 브랜드 커뮤니티의 신뢰 및 응답성 부분은 상호작용의 구성요인 중에서 연결성 부분에만 정의 영향을 미치는 것으로 나타났다. 셋째, 확신성은 상호작용요인 중에서 능동성과 연결성에만 정의 영향을 미치는 것을 알 수 있다. 다섯째, 공유의지가 상호작용의 구성요인 중에서 능동성과 연결성에는 영향을 미치고 있지만 반응성에는 영향을 미치지 못하는 것으로 나타났으며, 마지막으로 상호작용성이 펌 행위의도에 반응성 부분에만 영향을 미치지 못하였고, 방문충성도에는 모두 긍정적인 영향을 미쳤다. 앞에서 살펴본 내용을 바탕으로 브랜드 커뮤니티의 품질특성과 사용자특성요인 중에서 상호작용성에 많은 영향을 미치는 변수로 정보성, 확신성 그리고 사용자 특성요인인 공유의지를 들 수 있다. This study aims to explore the effects of interaction through UCC at online brand communication on scrap intention and visiting loyalty. According to study results, first, only information feature has positive effects on all interactions among quality feature of brand community; Second, confidence and responsiveness feature of brand community has positive effects on the connection feature among elements of interaction; Third, certainty has positive effects on activeness and connection among interaction elements. Fifth, while intention of sharing has positive effects on activeness and connection among interaction elements, it has no effects on the responsiveness. Finally, interaction does not affect the responsiveness of scrap intension, but has positive effects on visiting loyalty.

The incident of false aneurysm of internal maxillary artery in the oral and maxillofacial region is known to be very rare. One case of false aneurysm in the internal maxillary artery is presented, which was experienced in our department. The etiology of this case is regarded as the mandibular condyle fracture, and/or iatrogenic trauma during open reduction. Clinically, there were systolic bruit on auscultation, pulsation and massive bleeding during operation. The lesion was finally diagnosed with angiography and treated by embolization procedure. False aneurysm can cause so massive bleeding as to threat the life of the patients. Therefore accurate diagnosis and treatment is very important. Angiography enables the solid diagnosis for the clinical one. And as the embolization has many advantages over the ligation, it can be a good treatment method.

In this paper, we propose a new cache structure for effective error correction of soft error. We added check bit and SEEB(soft error evaluation block) to evaluate the status of cache line. The SEEB stores result of parity check into the two-bit shit register and set the check bit to '1' when parity check fails twice in the same cache line. In tills case the line where parity check fails twice is treated as a vulnerable to soft error. When the data is filled into the cache, the new replacement algorithm is suggested that it can only use the valid block determined by SEEB. This structure prohibits the vulnerable line from being used and contributes to efficient use of cache by the reuse of line where parity check fails only once can be reused. We tried to minimize the side effect of the proposed cache and the experimental results, using SPEC2000 benchmark, showed 3% degradation in hit rate, 15% timing overhead because of parity logic and 2.7% area overhead. But it can be considered as trivial for SEEB because almost tolerant design inevitably adopt this parity method even if there are some overhead. And if only parity logic is used then it can have 5%~10% advantage than ECC logic. By using this proposed cache, the system will be protected from the threat of soft error in cache and the hit rate can be maintained to the level without soft error in the cache.

Ameloblastoma of the maxilla is an unusual epithelial tumor of odontogenic origin. According to many authors and reports, ameloblastoma account for approximately 1% of all tumors of the jaws, but when pseudotumors and cysts are excluded, the ratio rises to 11%. Of these tumors,80% originate in the mandible, while 20% originate in the maxilla. Although it is considered benign histopathologically, it can behave in a slowly growing infiltrative fashion, with multiple recurrences and eventual intracranial, or even distant, spread. We clinically analyzed common site in maxilla, radiographic findings, recurrence rate, duration between treatment and recurrence, the presence and site of distant metastasis in 15 patients who were diagnosed as ameloblastoma of the maxilla and took treatments from 1985 to 1999 in Dept. of Oral and Maxillofacial Surgery, Dental Hospital, Seoul National University. In this paper, treatment outcomes and our clinical experiences of maxillary ameloblastoma are reported with review of literatures.
