Purpose : The purpose of this study is to evaluate the position of the mandibular canal in relation to the mandibular third molar by cone beam CT in cases showing a close relationship between the third molar and the mandibular canal on the panoramic radiograph. Materials and Methods : The panoramic images and cone beam CT scans of 87 impacted mandibular third molars in 60 patients were evaluated to assess the tooth relationship to the mandibular canal. The clearness of the canal wall and the vertical depth of the lower third molar were evaluated on panoramic radiographs. The lower third molars were assessed using cone beam CT to determine the proximity and position of the canal relative to the roots. Results : In the 66 cases where the canal wall was unclear on the panoramic radiographs, 58 (87.9%) of the third molars had contact between the canal and root; 34 (51.5%) canals were showed an inferior position and 22 (33.3%) showed a linguoinferior position on cone beam CT. Conclusion : Interruption of the canal wall on panoramic radiographs was highly predictive of contact between the mandibular canal and the third molar. Cross sectional CT may be indicated for localization of the mandibular canal in such cases.

다변화·대형화하는 국내 대형할인 식품유통환경 속에 점차 경쟁이 심화되면서 유통업체에서 자사브랜드를 만들어 경쟁력을 높이는 현상이 나타나고 있다. 최근 국내에서 마케팅 비용을 줄이고 초저가의 상품을 선정하여 고객에게 저렴하게 제공하는 "700마켓"이라는 하드디스카운트 스토어가 나타났다. 본 논문은 두드러진 콘셉트를 가지고도 소비자에게 인지도가 낮은 700마켓을 중심으로 성공적인 브랜드 구축을 위한 전략으로 자사브랜드 디자인 시나리오를 제시하였다. 이를 위해 국외 대표 하드디스카운트 스토어인 `알디`와 국내 식품유통업 브랜드들의 자사브랜드 디자인들을 분석하였다. 5년 이상 경험을 갖은 15명의 전문 브랜드 디자이너들이 8개의 디자인 항목을 5가지의 요소를 분석하였고, 2009년 4월 18일 소비자 직접 면접이 수원 매장에서 이루어졌다. 조사결과 현재 700마켓 브랜드가 가지고 있는 브랜드 아키텍처 및 브랜드 전략의 문제점들과 브랜드 인지도를 높여야 하는 요인이 도출됐다. 따라서 낮은 브랜드 인지도에 따른 신뢰도 부족과 저급한 제품으로 느끼게 하는 디자인의 개선을 통하여 브랜드 인지도를 높일 수 있는 네 가지 자사브랜드 디자인 시나리오를 결론으로 제시하였다. Globally the supermarkets have become more diverse in items they sell and bigger in their size over the past decade. In Korea, the retail environment, especially supermarkets have been going through dramatic change. With intense competition, supermarkets tend to develop their on private label brands. also recently supermarket industry start to operate hard discount store. "700market" is the first Korean Hard Discount Store. 700market is known to have provided very competitive prices opportunity to the consumers by cutting marketing costs. This paper focuses on private label brand strategies of 700market. Although 700market has distinctive brand concept, some problems of 700market were identified, including brand architecture and brand design problems. Throughout the case study of "ALDI", it allows comparative studies of Hard Discount Store`s brand strategy. Also, analysis of national supermarkets` private label brand strategies illustrated weakness of 700market brand. At least 5years experienced 15 brand design specialists analysed the 700market brand design. By scoring eight design materials with five categories of design matrix. Survey took place in April 18, 2009. 80consumers surveyed base on specialists analysis results. The survey results identified the lack of brand recognition of 700market, most of the consumer can not trust the quality of brand, because of poor brand execution. Therefore this brand needs to work on increase of its brand perception by making a private label brand. In conclusion, this paper suggests alternative private brand design scenario for differentiating the brand. There are four scenarios which 700market could use for making a distinctive brand perception.

Studies in individual level on Information Technology(IT) success are developed two areas: Studies on IT acceptance and use. Studies on end-user satisfaction. This study tried to combine two areas and develop the research model - the IT use and satisfaction model. The research model in empirically tested using data collected from end-user of groupware systems. The results of this survey are significant to general fitness of the research model. The rusults are summarized as follows: (1) perceived ease of use have significant positive influence on perceived usefulness. (2) perceived ease of use have not significant on attitude. (3) perceived usefulness have significant positive influence on attitude. (4) attitude have significant positive influence on groupware use. (5) groupware use have significant positive influence on end-user satisfaction. (6) end-user satisfaction have significant negative on groupware use.

Background: The usefulness of additional examination of Primovist-enhanced magnetic resonance images (MRI) during initial staging workup in hepatocellular carcinoma (HCC) patients who are candidates for curative treatment with no suspicious intrahepatic HCC lesion by liver dynamic computed tomography (CT) remains to be elucidated. Methods: A consecutive 104 patients who were initially diagnosed as having definite HCC without any suspicious HCC lesions by liver dynamic CT at our institution between December 2009 and May 2012 were enrolled. All of them showed Barcelona Clinic Liver Cancer (BCLC) stages 0 or A. We evaluated whether an additional examination of Primovist- enhanced MRI could affect on BCLC stage, directly comparing to liver dynamic CT. Results: Newly detected intrahepatic abnormal findings on Primovist-enhanced MRI were observed in 41 (39.4%) of the 104 patients. Eighteen (17.3%) patients had truly new HCCs, but 6 patients of initial BCLC stage A remained at this stage despite an increase in tumor number. Of the 104 patients, 31 (29.8%) and 73 (70.2%) had BCLC stages 0 and A HCC before Primovist-enhanced MRI, respectively, and 26 (25.0%), 71 (68.3%), and 7 (6.7%) patients had BCLC stages 0, A, and B HCC after Primovist-enhanced MRI, respectively. In 12 (11.5%) of the 104 patients, BCLC stage changed from 0 to A (5/31, 16.1%) or from A to B (7/73, 9.6%). Conclusions: Primovist-enhanced MRI can provide additional information regarding the detection of new intrahepatic HCC lesions during initial staging workup in patients with BCLC 0 or A stage, but with no suspicious HCC lesion by liver dynamic CT.

Colonoscopic examination is a safe procedure, however, unexpected complications can sometimes occur. Bleeding and perforation of the colon have been reported as the most common complications. Hemoperitoneum after colonoscopy is an unusual complication, but it may be catastrophic. We report on a 20-year-old man who experienced left low quadrant pain after undergoing colonoscopy. Hemoperitoneum was diagnosed using abdominal CT. A laparoscopic exploration was urgently performed, revealing a lacerated mesocolon of the descending colon. Bleeding of the injured site was controlled without complication. The patient recovered fully without signs of recurrent bleeding. This report implies that if the patient has persistent abdominal pain after undergoing colonoscopy, we should consider hemoperitoneum as one of the causes. To the best of our knowledge, no case of isolated laceration of the mesocolon of the descending colon after colonoscopy has been reported.

에크린 한공암종은 흔하지 않으며, 전이성 에크린 한공암종은 매우 드문 암이다. 에크린 한공암종은 표피내 한관에서 기원하는 피부 부속기 악성 종양으로, 대부분 에크린 한공암종은 항암치료와 방사선치료에 효과가 없으며, 따라서 유일한 치료방법은 전이되기 전에 국소 및 광범위 절제술을 시행하여야 한다. 본 환자는 두피에 발생한 에크린 한공암종이 점점 진행하여 피부, 림프절, 폐 등으로 전이하였고, 다수의 광범위 절제술에 이어 항암치료와 방사선치료를 받았지만, 결국 폐전이가 악화되어 사망하였다. 본 저자들은 항암치료와 방사선치료에 불응한 에크린 한공암종 1예를 치료에 대한 문헌고찰과 더불어 보고하는 바이다.
