Acinar cell carcinoma is a rare tumor that represents 1~2% of al1 pancreatic cancers. Clinical and radiologic findings are inconclusive in this disease Acinar cell carcinoma is characterized by rapid progression and early metastasis, which lead to its poor prognosis. A 41-year-o1d man was admitted to our hospital for abdominal pain. Abdominal computed tomography (CT) and positron emission tomography-computed tomography (PET-CT) showed a splenic mass, which was being invaded by a pancreatic tail mass and which had increased ^(18)F-fluorodeoxyglucose (FDG) uptake Primary radical distal pancreatectomy and splenectomy were performed. Pathologic findings revealed an acinar cell carcinoma of the Pancreas The patient underwent a total gastrectomy three months later because of gastric recurrence Four months later, multiple hepatic metastases were discovered, and the patient underwent a left hepatectomy During treatment with capecitabine, there was no evidence of tumor progression for 14 months. We report a case of metastatic pancreatic acinar cell carcinoma, which did not progress for an extended period while the patient was being treated with capecitabme.

임경희,장은진,김정범 대한생물치료정신의학회 2002 생물치료정신의학 Vol.8 No.2

연구목적 : 본 연구에서는 광장공포증을 동반하지 않은 공황장애 환자들(이하 비광장공포증군)과 광장공포증을 동반한 공황장애 환자들(이하 광장공포증군)의 공존병리와 증상의 심각도를 조사하여 두 질환의 본질을 규명하고 치료계획을 세우는데 도움을 얻고자 한다. 방 법 : 연구대상은 1998년 3월부터 2001년 7월까지 계명대학교 동산의료원 정신과에서 외래치료를 받아온 환자들로 비광장공포증군 26명, 광장공포증군 44명으로 구성된 총 70명이다. 평가도구는 9개의 증상차원을 평가하는 90문항으로 구성된 간이정신진단검사(SCL-90-R)와 공황장애의 필수적이고 전반적인 7가지 영역의 심각도를 평가하는 한국판 공황장애 심각도 척도를 사용하였다. 통계적 분석은 ANOVA, Chi-square test, student t-test, person correlaiton을 시행하였고, 통계적 유의수준은 p<.05로 하였다. 결 과 : 1) 광장공포증군의 광장공포증적 두려움과 회피의 정도는 경도에서 중등도 사이에 해당되는 것으로 나타났다(PDSS점수 : 1.46±0.94). 2) 인구통계학적 특성에 대해 광장공포증군과 비광장공포증군을 비교해 보면, 연령, 성별, 교육정도, 직업유무, 병력, 발병연령에서는 두 집단 간에 유의한 차이가 없었다(표 1). 3) 세 집단의 공존병리의 유형을 분석해 본 결과, 광장공포증군은 모든 증상차원에서 정상대조군 집단보다 유의하게 높은 점수를 얻었다. 비광장공포증군은 불안, 공포불안, 정신증 척도에서 정상대조군 집단 보다 유의하게 높은 점수를 얻었다(표2). 4) 광장공포증군은 비광장공포증군에 비해 신체화, 강박증, 적대감, 공포불안, 편집증척도에서 유의하게 높은 점수를 보였다(표 2). 5) 광장공포증군과 비광장공포증군의 심각도 비교에서는 내적감응적 두려움과 회피, 직무수행의 장해/고통, 사회적 기능의 장해/고통에서는 두 집단 간에 유의한 차이를 보이지 않았느아, 심각도 총점, 복합점수, 공황발작의 빈도, 공황발작 동안의 고통, 예기불안, 광장공포증적 두려움과 회피에서는 광장공포증군이 비광장공포증군에 비해 유의하게 높은 점수를 보였다(표 3). 6) 광장공포증군내에서 광장공포증적 두려움과 회피항목은 SCL-90-R의 정신증 척도를 제외한 신체화, 강박증, 대인민감성, 우울, 불안, 적대감, 공포불안, 편집증 척도와 유의한 정적상관관계를 보였다(표 4). 결 론 : 광장공포증군이 비광장공포증군에 비해 대부분의 필수증상의 심각도가 높을 뿐만 아니라 더 다양한 공존병리를 가지고 있음이 밝혀져 기본적으로 더 심한 질환임이 시사된다. 따라서 공황장애의 치료와 평가에 있어서 공존병리와 증상의 심각도를 함께 고려하고 공황장애에서 광장공포증이 동반되는 경우 이에 대한 더 적극적이고 집중적인 치료가 필요하겠다. Objectives : In this research comorbidity and severity of symptom of patients that have panic disorder without agoraphobia(PD) and with agoraphobia(PDA) were examined in order to study their nature more closely and also to help set up therapy plans. Method : 70 patients were diagnosed with PD(N=26) and PDA(N=44) by DSM-Ⅳ. SCL-90-R was administered to panic subjects and normal control subjects. PDSS were administered to panic subjects, the statistical analysis was conducted using ANOVA, Chi-square test, student t-test, Pearson Correlation analysis. statistical signifi-cance was p<.05. Results : 1) The degree of agoraphobic fear/avoidance of PDA indicated the level to from moderate(PDSS score 1.46 0.94). 2) There was no significant difference between the two groups(PD/PDA) in there sex, age, education level, occupation, duration of illness, onset of age. 3) After analyzing the comorbidity pattern of the three groups, PDA was significantly higher score than normal control group in all symptom level. PD had higher score than normal control groups in anxiety, phobic anxiety and psychotism. 4) PDA showed much a significantly higher score in Somaatization, Obsessive-Compulsive, Hostility, Phobic Anxiety, Paranoid Ideation when compared to PD. 5) There was no significant difference between the two groups(PD/PDA) in there interoceptive fear/avoidance, PDA had significantly higher scores than PD. 6) The agoraphobic fear/avoidance item within PDA had significant correlation with Somatization, Obsessive-Compulsive, Interpersonal Sensitivity, Depression, Anxiety, Hostility, Phobic Anxiety, Paranoid Idation except significant correlation with psychoticism. Conclusion : As it is shown clearly in all the results, PDA had a higher level of severity than PD. It was also clarified that PDA had a variety of comorbidity. Therefore when evaluating the treatment of Panic Disorder, One has to consider the comorbidity and severity. A more positively and concentrated treatment will be needed when panic disorder is accompanied by agoraphobia.

본 논문에서는 UWB (Ultra-WidrBand)시스템에 사용되는 초광대역 통과 필터를 설계하였다. 고역 통과 필터와 저역 통과 필터를 직렬 연결하여 구현하였다. 10.6 GHz의 cut off주파수를 갖는 저역 통과 필터는 단락된 전송선로와 개방된 전송선로를 이용 하여 구현하였고, 3.1 GHz의 cut of주파수를 갖는 고역 통과 필터는 L과 C의 lumped소자를 이용하였다. 시뮬레이션 결과 통과 대역에서는 S11 값이 18 dB의 값을 얻었으며 두개의 cut off 주파수에서는 S21의 값이 10 dB 감쇄한 결과를 얻었다. In this paper, it was designed ultra-wide band pass filter for UWB(Ultra-Wide Band) system. There was inplemented series connection of high pass filter and low pass filter. Low pass filter accessed cut off frequency of 10.6GHz was designed using short-circuited stubs and open-circuited stubs. High pass filter assessed cut off frequency of 3.1GHz was designed using lumped elements of L and C. Simulation results were obtained 18 dB of S11 from pass band and attenuated 10dB of S21 from two cut off frequencies.

Diesel engines which emit a lot of PM and NOx have been known as a main air polluter. Especially, diesel particulate matters (DPM) including black smoke are hazardous air pollutants to human health and environment. The nations retaining advanced engine technologies have reinforced emission regulations. To meet these regulations diesel engine manufacturers have developed low-emission diesel engines, aftertreatment equipments, alternative fuel technologies and so on. In this study, particle number concentrations characteristics according to particle size and engine driving conditions were analyzed when these low-emission technologies were applied. There was a tendency of increasing particle number concentrations from heavy-duty diesel engines with increasing engine rpm and load rate. In the cases of CDPF (Catalytic Diesel Particulate Filter), CNG (Compressed Natural Gas) engine and ULSD (Ultra Low Sulfur Diesel) more than 99% of particle number concentration were removed.

『말타의 유대인』과『볼포네』에 나타난 주인공의 기질연구

Christopher Marlowe is the father of English tragedy and the creator of English blank verse. Also the ardor of Marlowe's early Machiavellianism in The Jew of Malta. This play is first and foremost a play about a Jew whose overwhelming passion is for gold and the power that gold brings him. Barabas is a Jew who has gained and kept his wealth by Machiavellian devices and policies. The general terms of Machiavelli, even as interpreted by the Elizabethans, were capable of building a character on as grand a scale as Marlowe's other heroes. Barabas hates Christian, for he can see no goods in all their faith, but malice, falsehood, and excessive pride. The Jew of Malta is not a farce but tragedy. Ben Jonson is well-known as a playwright of the comical satires and powerfully influential in the younger wits who formed the Tribe of Ben in Elizabethan and Jacobean period. Jonson was a scholar and a classical antiquarian so he was on sound historical ground. Volpone is on the anti-acquisitive tradition inherited from the Middle Ages. In Volpone, we may find a philosophy of life that facilely divides the world into the knaves and their dupes, and identifying brains with roguery and innocence with folly. Volpone is an old magnifico of Venice who glories mere in the cunning purchase of his wealth than in the glad possessions. Volpone has no relative to whom to leave his fortune. This fact draws new clients with presents to his house daily. He is not motivated by greed in the beginning. He is much more of a gambler than a miser. But the development of mood is from an assured, self-satisfied cleverness at the beginning scene, through domination by the passions first of lust and then folly and then fear and then obsessive searching for amusement. Finally Volpone forfeits his complete identity, Iiterally lose himself when he has himself pronounced dead. Mosca is a parasite of Volpone as gadfly. In the beginning, he was a true parasite. He always satisfy his master's order for amusement and to assist master's plan. After that he is like a theatrical producer and becomes infatuated with his own cleverness. Self-possession ruins Mosca, as it does Volpone.

This study was carried out to improve the qualities and extend the shelf life ot Yukwa and Salyeotgangjung. traditional Korean cookies, using tine hot salt instead of oil as the popping medium. The Yukwa and Salyeotgangjtmg that had been popped using tine salt were stored at 25?for one or two months, and then compared their sensory evaluation, lipid contents and acid and peroxide values with those popped in oil. In the sensory test, the Yukwa base and popped rice expanded in the salts and stored for one month were preferred to those expanded in oil with regard to flavor and overall acceptability. With respect to the whiteness, off-flavor, and crispness, these properties those expanded in salt had stronger whiteness and crispness but a weaker off-flavor compared to those expanded in oil. The lipid contents of the Yukwa base and popped rice expanded in oil were 37.73 and 49.65%, respectively, which were significantly higher than in those expanded in salts (0.10 and 0.53%, respectively). The acid and peroxide values were larger in those expanded oil than in salts after 8 weeks storage. In view of the above results, the conclusion was reached that the Yukwa base and popped rice expanded in salts were less likely to provide a calorie intake and to become rancid over a long storage time.

In this study, the frequencies and types of questions about LIFE areas of the Science Curriculum of elementary school students were investigated through in-depth interviews with twelve 4th and 5th graders. The results of the research can be summarized as follows: (1) In conjectural question, the proportions of 'object exploration question' and 'object verification question' were high in all of the 4th graders and the students of low achievement level. (2) The numbers of causal questions generated by the 4th graders were much higher than those of the 5th graders. (3) The frequencies of the predictive, methodological, applicative questions were very low both in 4th and 5th grade students. (4) The numbers of conjectural questions were more in all students except the low achievement level of 4th graders at not-yet-taken contents than at already-taken ones. (5) The numbers of causal questions were more in all students except the low and middle achievement levels of 4th graders at not-yet-taken contents than at already-taken ones. (6) The numbers of the predictive, methodological, applicative questions of the 4th graders were more at not-yet-taken contents than at already-taken ones, whereas opposite trend in the 5th graders. (7) The numbers of students' curriculum-related questions were more in all students except the low and middle achievement levels of 4th graders at not-yet-taken contents than at already-taken ones. (8) As ways for solving or seeking answers about questions, the 4th graders suggested methods of consulting experts or teachers (23.9%), internet searching (21.6%), and books or science-related encyclopedia (20.3%), while the 5th graders suggested the internet searching (36.5%), consulting experts or teachers (24.8%), and books or science-related encyclopedia (17.7%). Based an these results, we suggest several ways for improving the question-posing abilities of the students and adequate use of students' questions in the process of science teaching learning.

The establishment of an efficient protocol for plant regeneration and micropropagation from leaf explant cultures of Chicory, Cichorium intybus L. var. sativus. is reported. Callus formation rate appeared 100% from explant in all growth regulators, but calli formed in the prensence of naphthaleneacetic acid (NAA) were appeared very compact and non-embryogenic state. The regenerated shoots were obtained from leaf explant cultures on solid MS medium containing different concentrations of cytokinins and auxin. The highest number of shoots (5.7) per explant and shoot growth (2.8cm) was obtained on MS medium containing 0.1 mg BAP L^-1 and 0.1 mg NAA L^-1. Indole acetic acid was the most suitable auxin for root formation among three auxins tested. 2,4-D had no effect on shoot and root formation.
