기존의 음원 추천 방법은 사용자 프로파일, 사용자 선호도, 사용자가 오디오 컨텐츠를 재생한 히스토리 목록, 전문가들의 추천 음악 등을 고려하여 각 사용자가 좋아할 만한 음악을 추천해 주는 방법을 사용해 왔다. 이 논문에서는 상황 정보를 이용한 음원 추천 방법을 바탕으로 사용자가 처한 상황을 고려하여 사용자에게 더 큰 만족을 줄 수 있는 음원 추천 방법을 제안한다.

Carcinoid tumors have been reported in a wide range of organs but most commonly involve the lungs, bronchi and gastrointestinal tract. Within the gastrointestinal tract, appendix is the most common location for carcinoid, followed by the distal small intestine, the rectum, and the stomach. Among these, primary involvement of the ampulla of Vater is extremely rare. We report a case of carcinoid tumor of ampulla of Vater. A 62-year-old man presented with epigastric soreness. Gastroduodenal endoscopy showed hyperemic bulging mass on ampulla of Vater and diagnosed as carcinoid tumor by histologic finding, with immunohistochemical study. In ^(111)In-octreoscan, tumor had regional lymph node metastasis, but no evidence of distant metastasis. Pancreatoduodenectomy with lymph node dissection was performed.

Radiofrequency ablation(RFA), as a form of minimally invasive therapy for hepatocellular carcinoma, has become an important treatment modality. Because of limitation of surgery, RFA has become standard therapy for hepatocellular carcinoma in some situations. But there are some complications of RFA such as bleeding, infection, hematoma, adjacent organ thermal damage including intestinal perforation, needle track seeding, and so on. There are few reports in the literature that systematically evaluate the incidence of needle tract seeding and its associated risk factors. And only 2 cases of needle tract seeding of hepatocellular carcinoma after RFA were reported in Korea. We report a case of needle tract seeding of hepatocellular carcinoma after RFA.

This paper presents the language model and the selection of candidate for words in sentence speech recognition for Korean language. In this paper, a small scale task for airplane reservation was used for recognition experiment. Considering the size of task, the language model was based on the formal language theory and gave priority to the lexical property of the task. The selection of candidate for words considered practical recognition rate of the task. The result of the experiments show that the application of language model was fitted with the recognition task and the proposed method for the selection of candidate was effective in sentence recognition.

Both genetic and environmental factors play important roles in the pathogenesis of Parkinson Disease (PD). The contribution of many environmental factors including dietary factor remains unproven. The purpose the study was to investigate the dietary habits, nutrient intake and dietary quality of Korean PD patients according to the duration of disease. PD patients were recruited from K and S university hospitals from May 2005 to January 2006. This study was carried out after approval by the Institute Review Board (IRB). British Brain Bank criteria was used to diagnose PD. The subjects were classified into 2 groups based on the duration of PD: < 25 months and ≥ 25 months groups. General characteristics, anthropometric measurements, food habits and dietary intakes were investigated. The results of this study were as follows: 1) The mean age of < 25 months group (66.9 ± 8.0 yr) was significantly higher than that of ≥ 25 months group (62.2 ± 8.8 yr) (p < 0.05). No significant differences were found for academic background, occupation, living status and social activity, however, numbers of diseases, exercise and family history of PD were significantly different. 2) Anthropometric measurements were not different between the two groups. 3) The frequency of taking snacks was significantly higher in < 25 months group and the amounts of alcohol consumption were significantly higher in ≥ 25 months group. 4) Daily intakes of most nutrients were very low compared with DRI. 5) The MAR score was significantly lower in < 25 months group (p < 0.05;) however, the scores of DVS, DDS and DQI were not significantly different. As a conclusion an overall nutrient intake and dietary quality of the Parkinson's Disease patients need to be improved regardless of duration of the disease and a well-balanced diet should be emphasized.

Objective: The puspose of this study was to determine the efficacy of unilateral posterior lumbar interbody fusion (Hemi-PLIF) by using one cage for the patients with focal type of degenerative lumbar diseases. Materials and Methods: The authors reviewed clinical and radiologic data of 43 patients with focal type of degenerative lumbar diseases who were performed unilateral Hemi-PLIF during the period between November 2000 and June 2003. The operation procedure was unilateral hemi-PLIF using titanium cages with transpedicular screw fixation. Results: The mean follow-up period was 11.2 months. The mean operation time was 197 minutes and the average estimated blood loss was 285mL. The clinical success rate according to Prolo's scale was achieved in 89.3%. of patients and the solid bony fusion was occurred in 96.4%. There were 2 patients of postoperative complications such as superficial infection and screw malposition. Conclusion: This procedure has been found to be an effective and safe procedure with rare complication. To compared with bilateral PLIF, less operation time, less blood loss, more fusion rate is noted.
수중식물과 침전물에 의한 용존산소 변화량 결정 : 하천모델 이용법;a Stream Model Approach

하천모델을 이용하여 한강 지류인 탄천에서 수초와 침전물에 의한 용존산소 변화량을 측정하였다. 수질자료에 따르면 탄천은 상류의 부영양화 지역 (Eutrophic Zone)과 하류의 강부수성 지역 (Polysaprobic Zone)으로 구분되며 상류는 수초의 광합성과 호흡이, 하류는 침전물 산소요구량이 수중 용존산소 농도 결정에 주 역할을 하고 있다. 하천조사는 1990년5월과 10월 2회에 걸쳐 2일간 연속적으로 실시되었다. 조사 결과 상류의 경우 수초 광합성과 호흡에 의한 매우 큰 용존산소 일주변화가 관찰되었다. 그러나 하류의 경우 침전물 산소요구량이 크고 수초 성장이 없기 때문에 일주변화가 거의 나타나지 않는 매우 낮은 농도가 측정되었다. 1차 조사시 상류에서 수중식물의 광합성량과 호흡양은 각각 55~100g 0₂/m²/day, 30~70g 0₂/m²/day으로 측정되었으며, 2차 조사시 각각 40~80g 0₂/m²/day, 25~55g 0₂/m²/day으로 측정되었다. 하류에서는 침전물 산소요구량이 1차 및 2차 조사시 동일하게 4~100g 0₂/m²/day로 측정되었다. The dissolved oxygen changes caused by aquatic plants and sediments were comput-ed in the Tancheon, a tributary of the HanRiver, by utilizing a stream model. According to the collected water quality conditions, the Tancheon was classified into two distinc-tive zones which were eutrophic zone in upstream area and polysaprobic zone in downstream area. The dissolved oxygen levels of the stream were determined mainly by the photosynthesis and respiration of the macrophytes in upstream area and by the sediment oxygen demand in downstream. Field data were obtained from two synoptic stream surveys performed during May and October, 1990 for two consecutive days The high diurnal dissolved oxygen variation was observed in upstream area due to an excessive growth of aquatic plants. In downstream area, however, little diurnal varia-tion with low dissolved oxygen level was observed, which would be attributed to high sediment oxygen demand and no discernible aquatic plant growth. In upstream area, the dissolved oxygen changes caused by the photosynthesis and respiration were ranged from 55g 100g 0₂/m²/day from 30 to 70 g 0₂/m²/day, respectively, during the first survey. The changes were ranged from 40 to 80g 0₂/m²/day for the photosynthesis and from 25 to 55g 0₂/m²/day for the respiration during the second survey, In downstream area, the sediment oxygen demands were measured from 4 to 100g o₂/m²/day during both surveys.
