The purposes of this study were to develop and introduce a novel intraoral appliance for bruxism composed of power switch and biofeedback device and further to examine inter- and intra-reliability of the appliance prior to clinical tests. The newly-developed appliance consisted of detection sensors, a central processing unit (CPU), a reactor and a storage unit and a displayer. Compact-sized, waterproof switches were selected as bruxism detection sensor and any sensor activation by clenching or grinding event was processed at the CPU and transmitted, by radio wave, to the reactor and storage unit and triggered auditory or vibratory signal, subsequently producing biofeedback to the patient with bruxism. The data on bruxing event in the storage unit can be displayed on the computer, making it possible analyzing frequency, duration and nature of bruxism. Cast models were obtained from ten volunteers with normal occlusion to evaluate reliability of the appliances. For inter-operator reliability on the intraoral appliances, each operator of the two fabricated the appliance for the same subject and compared the minimal contact forces provoking auditory biofeedback reaction in vertical, lateral and central directions. Intra-operator reliability was also investigated on the appliances made by a single operator at two separate times with an interval of two days. Conclusively, the newly-developed appliance is compact and safe to use in oral circumstance and easy to make. Furthermore, it had to be proven reliability excellent enough to apply in clinical settings. Thus, it is assumed that this appliance with the processor and the storage of data and auditory or vibratory biofeedback function is available and useful to analyze and control bruxism.

Mechanical properties of carbon coated $SiC_f/SiC$ composites have been investigated, in conjunction with a detailed analysis of microstructure. Especially, the fracture behavior of $SiC_f/SiC$ composites by the induction of carbon coating layers has been examined. The matrix region of $SiC_f/SiC$ composites with ultra-fine SiC powders were consolidated by a liquid phase sintering (LPS) process, using a sintering additive of $Al_2O_3-Y_2O_3$ powder compound. In this composite, plain and satin- woven Tyranno SA fabrics were also utilized as a reinforcing material. A carbon interfacial layer was coated around satin-woven SiC fabrics. The characterization of LPS-$SiC_f/SiC$ composites was investigated by means of SEM and three point bending test.

한반도 중서부 홍성지역은 지구조적으로 중국의 친링-다비에-수루대와 대비되는 충돌대일 가능성이 고려되는 지역이다. 홍성지역은 다수의 다양한 시기의 렌즈상 사문암체가 렌즈상 염기성암체와 함께 분포한다. 주 연구대상 사문암체 중 백동과 원노전 암체는 신원생대 알칼리화강암과 그리고 비봉암체는 고원생대 유구편마암과 접촉한다. 백동암체는 신원생대 알칼리화강암 암괴 및 고생대 후기 변성염기성 암괴를 포함하며, 비봉암체는 신원생대 알칼리화강암의 암괴를 포함한다. 세 암체 모두에서 중생대 관입암체가 인지되며, 비봉암체는 백악기의 화산암을 포함한다. 사문암체의 사문암에 대한 SHRIMP U-Pb 쇄설성 저어콘 연대결과는 백동 암체에서 시생대 후기부터 고생대 중기, 원노전과 비봉 암체에서 시생대 후기부터 백악기 전기까지 연대 범위를 보여준다. 비록 사문암화 과정에서 연대측정을 수행할 광물이 생성되지는 않지만, 가장 젊은 쇄설성 저어콘의 연대인 백동 사문암체의 고생대 중기와 원노전과 비봉 사문암체의 백악기 연대는 지금까지 알려진 사실과 달리 이들 사문암체가 고생대 중기 이후 혹은 백악기 전기 이후 사문암화되었을 가능성 또는 재동되었을 가능성에 대한 새로운 정보를 제공한다. 특히, 사문암체 내에서 나타나는 백악기 초기의 연대들은 사문암화 작용이 한반도 중서부 내에 분포하는 백악기 초기 화성작용과 관련되었을 가능성을 배제할 수 없다. 결과적으로 홍성지역의 연구대상 사문암체의 사문암과 사문암 내의 다양한 시기의 암괴들로부터 측정된 연대 결과들은 사문암화된 초염기성암의 사문암화 시기 및 사문암화 되는 지구조 환경 해석에 여러 가지 가능성을 제공하며, 연구지역의 다른 사문암체들을 포함한 사문암체에 대한 좀 더 자세한 지질연대학적 연구가 필요함을 지시한다. The Hongseong area of the central-western Korean Peninsula is considered to be a part of collision zone that is tectonically correlated to the Qinling-Dabie-Sulu belt of China. The area includes the elliptical-shaped serpentinized ultramafic bodies, together with mafic rocks. The studied bodies are in contact with the surrounded Neoproterozoic alkali granites at the Baekdong and Wonnojeon bodies and the Paleoproterozoic Yugu gneiss at the Bibong body. The Baekdong body contains the blocks of the Neoproterozoic alkali granites and the Late Paleozoic metabasites. The Bibong body also includes the Neoproterozoic alkali granite blocks. The Mesozoic intrusive rocks are also recognized at the Baekdong, Wonnojeon and Bibong bodies. On the other hand, the Early Cretaceous volcanic rocks are occurred at the Bibong body. The detrital zircon SHRIMP U-Pb ages of the serpentinites at three bodies range variously from Neoarchean to Middle Paleozoic at the Baekdong body, and from Neoarchean to Early Cretaceous at the Wonnojeon and Bibong bodies. Although serpentinization does not generally produce minerals suitable for direct isotopic dating, the youngest Middle Paleozoic age at the Baekdong body and the Early Cretaceous age at the Wonnojeon and Bibong bodies indicate the possible upper age limit for the (re)serpentinization. Especially, the Early Cretaceous serpentinization ages may be related to the widespread Early Cretaceous igneous activity in the central-southern Korean Peninsula. Age results for the serpentinite bodies and the included blocks of the studied serpentinized ultramafic bodies in the Hongseong area, therefore, provide several possible interpretations for the serpentinization ages of the ultramafic rocks as well as the geotectonic implications of serpentinization, requiring more detailed study including other serpentinized ultramafic bodies in the Hongseong area.

Purpose: The subepithelial connective tissue graft(SCTG) has been proven to be a highly predictable treatment modality for coverage of gingival recession. This case report was performed to evaluate the effect of various root coverage procedures using SCTG on gingival recession. Materials and Methods: Three patients presents with Miller's class I recession defect on the maxillary canine. Each other SCTG(coronally advanced flap, Bruno's Tech., envelope Tech.) were performed for root coverage. Clinical parameters assessed included recession depth, recession width, and keratinized gingival width. Measurements were taken at baseline and 2 months and follow up end. Results: The average of root coverage was 4 mm(100% of the pre-operative recession depth) at the 2, 5 months examination. The average increase of keratinized tissue between the baseline and the 2 months amounted to 3.2mm. Conclusion: Within the above results, various root coverage using SCTG is an effective procedure to Miller's class I recession defect and patient could be satisfied aesthetic requirement.

Purpose: The purpose of this study was to evaluate the clinical benefits of preoperative percutaneous transhepatic drainage (PTGBD), especially regarding morbidity and mortality, in patients aged 60 or older with acute cholecystitis. Methods: A retrospective study was done on a series of elderly patients (>60 years old; n=132) who had been diagnosed between January 2007 and December 2009 as having acute cholecystitis. The patients were divided into 4 groups; cases in which only laparoscopic cholecystectomy (LC) was done (Group 1, n=84), cases in which LC was done after preoperative PTGBD (Group 2, n=15), cases in which only open cholecystectomy was done (Group 3, n=23), and cases in which open cholecystectomy was done after preoperative PTGBD (Group 4, n=10). We analyzed between group differences in surgical outcomes including periods of postoperative fast and postoperative hospital stay, OP. morbidity, and open conversion rate. Results: Patients in Group 1 had fewer underlying medical problems and lower ASA scores than patients in groups 2, 3, or 4 (p<0.05). Mean operating time in Group 2 (113.66±107.5 min) was significantly longer than in group 1 (72.02.9±34.2 min) (p<0.05) and the open conversion rate was higher (8.33% vs 26.67%). But, blood loss (ml) and OP time in Group 2 were lower than in Group 3 or 4 (p<0.001). Postoperative recovery progression (periods of postoperative fasting and length of postoperative hospital stay) of Group 2 were better than in groups 3 or 4 (p<0.001). Conclusion: Pre-operative PTGBD procedures in elderly patients with acute cholecystitis is a good clinical option as a pretreatment to a cholecystitis operation.

『립 밴 윙클』: 다양한 민담적 특성 들 위에서 창조되어진 최초의 미국 본격 단편 소설

김성원 ( Seung Won Kim ) 건국대학교 동화와번역연구소(구 건국대학교 중원인문연구소) 2006 동화와 번역 Vol.11 No.-

워싱턴 어빙은 민담적 특질들을 전통미국 단편 문학으로 변형시키기 위하여 립 밴 윙클 을 창조해 내었다. 다양한 민담적 요소들은-작품배경, 등장인물, 구조, 모티브, 그리고 스타일-어빙의 상상적인 이야기에 많은 영향을 주었다. 비록 어빙의 립 밴 윙클이 실제 민담은 아니지만, 이 이야기는 명백하게 주요한 민담적 특성들 위에서 구성되어졌다. 립밴 윙클에서 주요한 모티브들인 `잠들기`(sleep)와 `변화` (transformation)는 독일의 민담 피 『피터 클라우스』(Peter Klaus), 중국의 민담 『왕치 이야기』(the Story of Wang Chih), 그리고 한국의 민담 『조신몽』(Chosin`s Dream) 등에 나타난 주요 모티브들과 매우 유사하다. 더욱이 립 밴 윙클에 나타난 미국적인 특색들은 이 이야기를 민담적인 기원으로부터 진정한 미국의 이야기로 변환시킨다.

떠나보낼 수 없는 세월에 나타난 역사의 번역

김성원 ( Seung Won Kim ) 건국대학교 동화와번역연구소 2012 동화와 번역 Vol.23 No.-

『떠나보낼 수 없는 세월』은 이차 대전 당시 한국에서 유년기를 보내며 다양한 시련들을 극복하는 열 살배기 주인공 박숙안의 성장이야기를 다룬 미국 아동 청소년 독자들을 위한 작품이다. 이 작품에서 작가 최숙렬은 자신의 자전적 경험들과 한국의 역사라는 사실을 소설이라는 허구화된 문학 양식의 소재로 사용하여 작품의 배경을 설정하고, 인물을 형성하고, 플롯을 전개시켜 나가며, 주제를 재현한다. 이러한 최숙렬의 자전적 글쓰기는 포스트모던 민족지학에서 활발하게 논의되는 문화 쓰기 논쟁과 매우 밀접한 관련이 있다. 왜냐하면 포스트모던 민족지학자들은 민족지를 기술할 때 대상이 되는 사회, 문화, 그리고 역사의 경계 안에 실재 거주하는 사람들의 목소리, 관점, 그리고 상황이 충분하게 반영되어야 한다고 주장하기 때문이다. 더 나아가 그들은 민족지가 단순히 외부자의 시각에서 대상물을 객관화하고 표준화하여 진공상태에서 기술될 수 없다고 주장한다. 따라서 포스트모던 민족지학자들은 민족지가 기술자의 주관성과 창의성에 의하여 다양한 방식으로 기술되어야 한다고 주장하며, 이러한 창작 과정을 문화 번역이라고 규정한다. 이와 같은 측면에서 한국계 미국 1세 작가 최숙렬의 『떠나보낼 수 없는 세월』은 단순히 아동 청소년을 대상으로 하는 자전적 소설이 아닌 민족지의 한 형태로 분류 될 수 있으며, 문화 번역이라는 새로운 관점에서 재해석 될 수 있는 작품이다. 왜냐하면 최숙렬이 이차 대전 당시 한국의 역사에 대하여 잘 모르는 미국 아동 청소년 독자들에게 한국인들의 비극적인 삶과 역사를 바로 알리는 일환으로 소설적인 역사 쓰기(fictional history)를 하고 있기 때문이다. 흥미로운 점은, 최숙렬이 내부자의 시각에서 자신의 유년기와 한국의 역사를 회고할 뿐만 아니라 외부자인 미국 아동 청소년 독자들과 출판시장을 고려하여 그들이 이해할 수 있는 관점, 언어, 그리고 형식으로 변환하고 있다는 점이다. 이러한 변환 과정에서 작가 최숙렬은 포스트모던 민족지학자들이 주장하는 작가 고유의 관점과 비전에 의거하여 기술 대상인 한국의 역사를 번역하고 있으며, 이러한 최숙렬의 문화 번역은 미국 공립학교와 공공도서관의 이차 대전 관련 참고도서로 선정되는 것으로 그 가치를 입증하였다. Year of Impossible Goodbyes is a coming of age story of a ten-year old Korean girl Sookan Bak who had to overcome various hardships originating from the swirl of the World War II. In this work, the author, Sook Nyul Choi uses both her autobiographical experiences and Korean history, converting facts into fictional materials in order to set the background, create characters, develop plot, and represent a theme. This writing style of Sook Nyul Choi is closely related to the debate of writing culture in "postmodern ethnography" because most postmodern ethnographers argue that ethnography should be fully reflected in the inhabitants` voices, perspectives, and real situations, which are located in the boundary of the same society, culture, and history. Furthermore, they propose that ethnography should be an outcome of sequence of cultural interpretation because ethnographers as outsiders should not give an account of their describing target culture under vacuum through standardizing and perceiving them objectively. Here, I use the notion of cultural interpretation in ethnography as a new way of examining Sook Nyul Choi`s Year of Impossible Goodbyes, and I observe that Year of Impossible Goodbyes as a fictional history, which was not only written by the first generation of Korean American writer but also dealt with the history of Korea. In this historical account, Choi fictionalizes various historical events in Korea in order to help young American reading publics better understand a tragic history of Korea during World War II, which still has remained unknown to most Americans. Interestingly, Choi reviews both her own childhood and Korean history from the insider`s view, first. And then, Choi converts them into fictional history using an outsider`s language and forms to satisfy both of the appetite of reading publics and the expectation of publishing markets in America. While conducting this conversion, Choi interprets Korean history found within the notion of postmodern ethnographer, and her interpretation of Korean culture is officially approved by American reading publics. The evidence is that Choi`s book is displayed as one of the reference books on World War II in both public and school libraries all over America.

Background: Cancers of the maxillary sinuses are not common and are the most difficult head and neck malignancies in which to make an early diagnosis. Objectives: This reports was conducted to evaluated the efficacy of combination therapy and the relationship between the treatment modalities and their outcome of maxillary sinus cancers. Materials and Methods: We retrospectively analyzed a clinical datas of 46 patients who were treated at the department of Otolaryngology-Head and Neck Surgery. The Catholic University of Korea over 10 years between 1987 and 1996. Results: According to AJCC TNM system, 35 patients presented with T4, 10 with T3, one with T1. Two patients were treated with radiotherapy alone, 4 patients with chemotherapy alone, 17 patients with radiotherapy and chemotherapy, 23 patients with combination of surgery, radiotherapy and chemotherapy. The overall 5 years survival rate for combination therapy group were 57%, but 23 patients treated with the other treatment modalities all died within 2 years except two cases with chemotherapy and radiotherapy or radiotherapy alone. There was a statistical trend for better survival and local control in those patients treated with combination therapy than others(p
