Gastritis cystica profunda (GCP) is a disease characterized by hyperplastic and significant extension of cystic dilatation of the gastric mucous glands, which results in a cystic lesion in gastric submucosa. It often occurs on the part of gastroenterostomy, but can be found in the stomach without any previous surgery. GCP has variable gross finding including solitary polyps, diffuse ones, submucosal tumors, and rare giant gastric mucosal fold. It is difficult to tell GCP from a cancerous lesion by gross finding that the disease demands a necessary tissue biopsy, though GCP is commonly showed as a benign in the progress. We report a case of GCP in polypoid types diagnosed by endoscopic polypectomy.

In this paper procedures for collecting, analyzing and implementing audio-visual speech are described. First, we defined a list of Koren vesemes according to the articulatory positions of the phoneme set. By the list we defined pronunciation list. Based on the list audio-cisual speech is collected. Next, part of the collected audio-visual speech is analysed to obtain variation of coordinates which corresponds to the motion of real articulatory organs. Finally the measured result is applied to the graphic facial model to synthesize audio-visual speech.

Objective: The purpose of this study was to compare preceptors and new graduate nurses on their perception of preceptor teaching effectiveness. Methods: The participants were 90 new nurses and 90 preceptors who worked in A medical center. The data were collected from July 1 to September 30, 2008. A cross-sectional descriptive survey was done using a structured questionnaire. Results: New nurses' perception (4.07±.44) of the preceptor teaching effectiveness was significantly higher than perception of the preceptors (3.57±.37). Fifty five percent of new graduate nurses reported a lack of coherence in the preceptor's practice guidelines. For 5 causal factors classified on the teaching effectiveness, the factor of 'Professional knowledge and ability' showed the highest score, but 'Interpersonal and communication skill' got lowest score for both group. Preceptors responded that they did not have enough time to teach well because of their heavy workloads. Conclusions: These results suggest that the preceptors need appropriate compensation and education opportunities, and new graduate nurses need consistent education by the teaching professionals. Therefore, it is important to give preceptors full charge of the preceptorship. Also, it will be necessary to develop education programs to enhance interpersonal and communication skill for preceptors and new nurses.
내시경적 밴드 결찰술로 치료한 출혈을 동반한 위 혈관이형성증 1예

Gastric angiodysplasia is vascular ectasia in mucosa and submucosa of the gastric wall. It is an uncommon cause of upper gastrointesinal hemorrhage that may occur in the stomach or duodenum. There are many kinds of endoscopic treatments, such as argon plasma coagulation, electrocoagulation, heat probe, and submucosal injection of hypertonic saline mixed with epinephrine for gastric angiodysplasia. However, these treatment methods are associated with high rate of rebleeding. In order to avoid the recurrence, endoscopic band ligation has recently been used as an alternative method for endoscopic treatment of gastric angiodysplasia. We encountered a case of gastric angiodysplasia that presented with overt bleeding and anemia, and was successfully treated with endoscopic band ligation.

In comparison with other studies, in particular, the emission of indoor HCHO in new apartments were very serious and Vacs showed below the Japan's guidelines (260 ㎍/㎥) excepting toluene (324.31 ㎍/㎥). Concentration of volatile organic compounds (VOCs) including aldehydes in indoor air was analyzed at 3 new apartments (at the lower, middle and upper floors of each apartment) during the Spring in 2004. The sample gases of Vacs and aldehydes were collected by Silicon canister (6 L) and 2,4-DNPH cartridges, and the analysis was made by the GC/MSD and PLC. As a result of the analysis, formaldehyde (HCHO) amongst aldehydes was found the highest (874.63 ppb) at the upper floor of C Apt., and the aldehydes' concentrations were S > C > K Apt. each. Also it did not show an apparent variation of characteristics according to floor. The concentration of VOCs was the highest (819.22 ppb) at the upper floor of C Apt. which exhibited in proportion with height.
데이터 글러브를 이용한 손 제스처 기반 3차원 게임 구현

데이터 글러브(Data Glove)는 손 제스처를 정의하여 시스템을 제어하는 입력장치로 가상현실기술 및 교육, 의료, 산업분야에서 많이 사용되고 있다. 이는 가상현실 속에 존재하는 사물을 현실에서 제어하게 함으로써 사용자에게 마치 현실 세계의 사물을 제어하는 느낌을 주는 장점을 가지고 있다. 이에 본 논문에서는 이러한 데이터 글러브의 장점을 이용하여 3차원 게임에 적용시키는 방법을 제안한다. 먼저 데이터 글러브로 제스처를 정의하고, 트래커(Tracker)와 연동하여 시스템을 구현한다. 구현된 시스템을 실험하기 위해서 OpenGL로 인형 뽑기 게임을 구현하고 사용자가 데이터 글러브를 착용 후 정의된 제스처를 통해 게임을 제어하도록 한다. 본 논문에서 제안한 방법은 사용자들에게 좀 더 높은 몰입감을 제공하며, 향후 게임 산업 발전에도 많은 영향을 줄 것으로 기대한다.
