소프트웨어의 규모가 커지고 다양해짐에 따라 고객이 원하는 요구사항을 정확하게 이해하여 표현하는 것의 중요성이 강조되고 있다. 특히 개발 초기에 요구사항은 추상적이고 개념적이기 때문에 핵심적인 시스템의 요구사항을 도출해서 명세하는 작업은 쉬운 일이 아니다. 기술적인 측면에서 이론적으로 다양한 분석과 검증기법이 소개되고 있지만 실무적으로는 요구사항을 명확하게 도출하기 힘들다. 본 논문에서는 고객이 원하는 요구사항을 명확하게 도출하기 위해, 텍스트언어학(textlinguistics)의 거시구조 개념을 이용한다. 먼저, 서술적으로 명세 된 요구사항을 텍스트언어학(textlinguistics)의 거시구조로 분석하였고 다음으로 거시규칙을 적용하여 거시명제를 도출하여 요구사항을 명확히 정의하도록 하였다. 마지막으로 도출된 거시명제를 이용하여 Use-case Model로 문서화하는 방법을 제시하도록 한다. As software is varied and grew in size, the importance of clear understanding and representing customer's need, has been emphasized. It is not easy to drive and define critical system needs, since requirements in early stage of the development, is and conceptual. Technical perspective view, Several theoretical analysis methods and validation techniques are introduced, but in practice, it is hard to drive clear customer's requirement. In this paper, to drive clear customer's requirements, Macrostruktur concept of textlinguistics is used. First, Macrostruktur of textlinguistics is used to analysis descriptive requirements. Second, Macrostruktur-rule is applied to analyzed Macrostruktur data in order to derive Macrostruktur-propositions. Finally, it is proposed to generating Use-case model using derived Macrostruktur-propositions.

Background/Aims: The major origin of thrombocytopenia in liver cirrhosis is attributed to enlarged spleen. In order to determine the influence of thromboprotein (TPO) on the origin of thrombocytopenia in liver disease, we measured serum TPO levels in patients with chronic liver diseases. Methods: The study included 18 controls, 26 patients with chronic viral hepatitis, 35 patients with viral liver cirrhosis, and 28 patients with alcoholic liver cirrhosis. We determined their serum thrombopoietin levels by ELISA. Results: The TPO levels of patients with chronic viral hepatitis (147.9 ± 40.9 pg/mL) was significantly higher than those in patients with viral cirrhosis (95.9 ± 50.0 pg/mL), alcoholic cirrhosis (100.8 ± 43.5 pg/mL) or controls (108.1 ± 41.7 pg/mL). In the patients with viral and alcoholic liver cirrhosis, TPO showed a significant positive relationship with prothrombin time (ρ=0.4315, p=0.011 vs ρ=0.4171, p=0.030) and albumin (ρ=0.4939, p=0.003 vs ρ=0.4852, p=0.010). However, TPO levels had a significant inverse relationship with Child-Pugh score (ρ=-0.6151, p=0.000 vs ρ=-0.4658, p=0.014). Conclusion: Serum TPO levels were elevated in patients with chronic viral hepatitis by compensatory mechanism. Along with hypersplenism, low TPO production may play a role in the development of thrombocytopenia in patients with liver cirrhosis, but further studies are needed.

Bus makers have applied Zn-Fe coated steel sheet to bus outer bodies because of its high corrosion resistance. But it was difficult for the makers to phosphate the bus bodies by themselves because the size of bus body was too big to immerse it in phosphating bath. Therefore. the bus makers have required steel makers to provide Zn-Fe coated steel sheet that was phosphated directly in EGL(Electro-Galvanizing Line). But it was also found to be difficult that Zn-Fe electroplated steel sheet was phosphated in the high speed continuous EGL. because the phosphating time in the process was too short to complete the phosphating reaction. It was observed on this process that the Zn-Fe coated steel sheet could be phosphated perfectly even in as short reaction time-about 3~7 seconds-as EGL by precipitating copper on it before phosphating. Precipitating copper on Zn-Fe coated steel sheet was carried out by dipping the steel sheet for 3~7 seconds in copper solution of about 0.5~1.0g/l concentration. This method. reducing phosphating time by precipitating copper on Zn-Fe coated steel sheet before phosphating was named as Cu-Dash treatment.

Background/Aims: Pelvic floor location and mobility vary according to the defecation posture. Authors investigated possible effects of the change of defecation posture on the patients with pelvic outlet obstructive constipation among patients with chronic idiopathic constipation. Methods: Subjects included in the study were 32 patients with pelvic outlet obstructive constipation (24 spastic pelvic floor syndrome, 8 perineal descent syndrome). From all the subjects, defecographies of both resting and straining phases were obtained for three different postures (sitting, leg elevating and squatting). Results: In the patients with spastic pelvic floor syndrome, the anorectal angles of straining phase in squatting position were 117.93±3.58캻nd 118.2±4.94?respectively. These values were significantly greater than those measured in sitting position (resting 93.75±6.74?straining 95.17±7.77?and leg elevating position (resting 99.42±4.79?straining 98.67±5.76?(p<0.01, p<0.01, respectively). In addition, in the patients with perineal descent syndrome, perineal descent in squatting position revealed no significant differences compared with sitting and leg elevating positions. Conclusions: In patients with spastic pelvic floor syndrome, squatting position increases the anorectal angle. Although further studies are needed to support our ideas, this study demonstrates that patients with spastic pelvic floor syndrome can have benefit from the Korean traditional defecation posture by increasing the anorectal angle.

가스 괴저는 외상이나 수술 후에 주로 클로스트리듐에 의해 발생하나 드물게 비클로스트리듐에 의해서도 발생할 수 있다. 저자들은 음주력 외에 당뇨 및 외상이 없던 환자에서 구강 및 위장관의 상재균인 S. constellatus에 의해 가스괴저가 발생한 증례를 최초로 경험하였기에 문헌고찰과 함께 보고하는 바이다. Gas gangrene is usually caused by clostridial species; non-clostridial gas gangrene is infrequently reported. S. constellatus belongs to the Streptococcus milleri group, which are considered part of the normal flora and frequently associated with abscess formation. We report a rare case of spontaneous gas gangrene caused by S. constellatus. An 86-year-old man was admitted with gas gangrene of the left hip. He was treated with surgical debridement of the necrotic tissue, and antibiotic therapy, and had a satisfactory clinical course. (Korean J Med 75:119-121, 2008)

Acute pancreatitis is a rare complication of 5-aminosalicylic acid (5-ASA) treatment. We recently experienced a case of acute pancreatitis secondary to 5-ASA in a patient with ulcerative colitis (UC). A 25-year-old man was admitted for bloody diarrhea and lower abdominal pain. Mesalazine was used under the diagnosis of ulcerative colitis, but the symptoms were not improved. After symptomatic improvement by steroid treatment, mesalazine was restarted for maintaining the remission. On the next day, he had a sudden severe epigastric pain with elevation of serum amylase and lipase levels. Drug- induced pancreatitis was suspected, and the mesalazine was discontinued. His abdominal pain disappeared, and his serum amylase and lipase levels returned to normal. After the administration of sulfasalazine, however, pancreatitis was relapsed. In conclusion, we suggest that drug-induced pancreatitis should be suspected in any patient who develops new abdominal pain while receiving 5-ASA. (Korean J Gastroenterol 2002; 40: 282-285)

Background/Aims : An increase in splanchnic blood flow in both artery and vein has been observed in activeulcerative colitis (UC). Doppler ultrasonography (US) is a non-invasive evaluation method of splanchnic arterialinflow in superior mesenteric artery (SMA). This study was undertaken to assess the usefulness of Doppler Usin detecting changes of the hemodynamic variables in patients with UC. Methods: Twenty-two patients with UC(14, active UC; 8, inactive UC) were studied, and compared with 14 matched healthy subj ects. Flow velocity,resistance index (RI), and pulsatile index (PI) of the SMA were evaluated by Doppler US. Results: Peaksystolic velocity was significantly higher in patients with active UC than in patients with inactive UC and control (178±53 m/sec vs. 117±15 m/ sec, 111±24 m/ sec; p<0.05). The PI of SMA was significantly lower inpatients with active and inactive UC than in control (1.58±0.53, 1.7±0.52 vs. 2.9±0.44; p<0.05). Minimaldiastolic velocity and RI of the SMA were not significantly different among three groups. Conclusions: Peaksystolic velocity of SMA reflects the activity of the disease in patients with UC. Doppler US in patients with UC is an important non-invasive, readily available method to evaluate the activity of the disease and predict itsrecurrence. (Korean J Gastroenterol 2002;39 :192-197)

N/A Background: Liver cirrhosis may be considered one of the most common cause of acquired immunodeficiency. Alcohol abuse may be predisposing factor to infections in patients with liver cirrhosis, so we compared the rate of spontaneous bacterial peritonitis (SBP) and other bacterial infections in alcoholic and viral liver cirrhosis. Methods: We studied 188 patients who had been diagnosed with liver cirrhosis from January 1995 to June 2000 and evaluated the frequency of bacterial infections (SBP, pneumonia, urinary track infection, bacteremia, infectious colitis) retrospectively according to cause and degree of cirrhosis. Results: Among 188 patients (alcoholic 76, viral 112), 64 patients (34%) presented with bacterial infection at hospitalization, 33 (43%;33/76) of 64 subjects were alcoholic and 31 (28%;31/112) of 64 subjects were viral liver cirrhosis. The rate of bacterial infections was higher in alcoholic liver cirrhosis than viral cirrhosis (p<0.05). The rate of SBP and other bacterial infections were more frequent in patients of Child-Pugh class C than in those of Child-Pugh class A and B (p<0.01, p<0.05) respectively. Patients of alcoholic liver cirrhosis were more susceptible to bacterial infection than those of viral liver cirrhosis with Child-Pugh class A/B (p<0.05), but no difference was noted in patients of Child-Pugh class C (p>0.05). Conclusion: This results suggest that the rate of bacterial infections are more common in alcoholic than viral liver cirrhosis in relatively early stage and it may be influence the prognosis of liver cirrhosis.(Korean J Med 62:159-164, 2002)
