본 논문에서는 복합프로그래밍 지원 환경에서 필요한 점진적 코드생성에 관한 연구를 하였다. 점진적 코드생성은 프로그램의 수정후 불 일치한 트리가 발생되었을 때 최소한의 트리를 방문하여 항상 수행 가능한 프로그램 상태를 유지할 수 있게 해준다. 또한 대상 언어에 대한 구문을 미리 인식하고 있어 구문 오류가 발생될 때 마다 즉각 수정이 가능하며, 정적 의미 분석은 context-free 또는 context-sensitive에 대한 오류를 방지할 수 있다. 본 논문에서는 점지누적 애트리뷰트 평가 알고리즘을 사용하여, 추상구문 트리에 p-code를 첨가하여 점진적 코드생성을 실험하였다. This paper is a study concerned with incremental code-generation which is in need of state which supports integrate programming environments. When after modification of the program the inconsistent tree is found, the incremental code-generator moves minimal tree and then makes the state of program capable of execution and keep it. The incremental code-generation recognized already the syntax of language. When the syntax errors occur, the program can modify immediately. Syntatic analysis can protect against context-free and context-sensitive errors. This paper uses incremental attribute evaluation algorithms and then research into incremental code-generation with abstract syntax tree adding p-code.

Pleural effusion in a patient with multiple myeloma due to plasma cell involvement of the pleura has been reported infrequently. We report a case of multiple myeloma with pleural involvement presenting bone pain and dyspnea in a 69-year-o1d woman. On the physical examination, the patient looked chronically ill with bedridden state. There was a palpable mass on the left posterior lower chest, firm but not tender and decreased breathing sound in the left lower lung. Laboratory finding revealed amemia, elevation of ESR, globulin, and calcium. X-ray of the chest showed pleural effusion in the left lower lung, and multiple pathologic fractures in the both ribs. X-ray of the skull, and pelvis revealed multiple punched-out osteolytic fractures in the both ribs. X-ray of the skull, and pelvis revealed multiple punched-out osteolytic lesion, and compression fracture in the lumber spine. Serum and urine electrophoresis revealed a M-spike. Serum and urine immunoelectrophoresis demonstrated an IgA-kappa monoclonal protein. Thoracentesis revealed serosanguinous fluid but not containing atypical plasma cells. Bone marrow examination showed 16.7% of immature plasma cells. With first cycle of melphalan, prednisone chemotherapy, improvement of pain and disappearance of pleural effusion was observed.

We performed costochondral grafting in mmandibular reconstruction including condyle replacement in 5 patients which have 4 cases of ameloblastoma, 1 case of resorption of left condyle due to osteomyelitis. We harvested the 6 th costochondral cartilage of unaffected side. No specific complications were appeared with unexpected fracture of costochondral junction and infection of operation site, These patients show 30-45mm at month opening, near normal of affected side, near normal or normal of unaffected side at lateral excursion. Postoperative coureses was uneventful with improved cosmetic and functional results. Our report is indicated that the costochondral graft is satisfactory to reconstruct mandibular defect including condyle replacement, especially in growing patients.

Double pyrolus, one of the relatively rare anomalies of the gastrointestinal tract, is a fistulous communication between the gastric antrum and the duodenal bulb. The first case of a double Pylorus was reported in 1969 by Smith, since then several cases have been reported. Recently, as the frequency of examining upper gastrointestinal series and endoscopy increases, it occurs more frequently and a few cases have been described in our country. According to the reports previously published, it resulted only from cysts, diverticla, atresia, band, membrane malformation of the pylorus, however, it might be also caused by penetration, complication of peptic ulcer. We report a case of double pylorus in a 67-year old man with prolonged administration of corticostetoids due to lumbago who has complained epigastric pain which was confirmed by endoscopy and biopsy.

우리나라와 같이 B형 간염 바이러스의 유병율이 높은 지역에서는 B형 간염 바이러스 뿐만 아니라 HCV에 대한 항 바이러스 효과도 동시에 시행함이 유용할 것으로 사료되었다. 본 연구에서는 茵蔯淸肝湯을 이용하여 B형 간염 바이러스에 대한 抗 바이러스 효과를 PCR을 이용하여 HBV의 DNA를 검색하였다. 茵蔯淸肝湯이 처리된 처리군의 경우 대조군에 비하여 농도 의존적으로 B형 간염 바이러스의 표면항원 생산을 억제하였고, PCR을 이용하여 증폭한 경우에도 증폭된 DNA의 양은 감소하였다. 또한 C형 간염 바이러스에 대한 抗 바이러스효과를 검색하기 위하여 복제에 필수적인 단백질인 HCV helicase의 ATPase에 대한 활성 억제 효과를 조사하였다. 茵蔯淸肝湯이 HCV helicase의 ATPase 활성을 억제하는 효과가 있음을 확인한 후 dose-respond에 따른 실험을 수행하여 HCV helicase의 ATPase 활성을 억제함으로써 탈인산화 되지 않은 ATP의 양을 이용하여 PSL로 분석한 결과 茵蔯淸肝湯이 HCV helicase의 ATPase 기능에 대한 억제효과가 우수함이 확인되었다. 이상의 결과로 보아 茵蔯淸肝湯이 B형 및 C형 간염 치료에 동시에 응용될 수 있을것으로 사료된다. For the purpose of investigate the inhibition effects of Injinchunggantang on Hepatitis and C Virus. The inhibition experiments were as follows : 1. The inhibition effects of Hepatitis B surface antigen production was remarkably increased in the pretreated group of Injinchunggantang compared with control group. 2. Amplified PCR products of HBV-DNA in culture media was considerably decreased in the pretreated group of Injinchunggantang compared with control group. 3. Results of ATP quantitation and ATPase inhibition percent was increased pretreated group of Injinchunggantang. Also ATPase activity of HCV helicase inhibition assay was increased with a dose dependent manner. These results may suggest that Injinchunggantang will have the inhibition effects of Hepatitis B and C Virus.

Purpose : To determine if ultrasonography is a reliable technique to assess masseter muscle sites within intra- and interobserver and the scanning level and/or the muscle condition affect local cross-sectional dismension (LCSD) measurements of masseter muscle. Materials and Methods : 10 subjects without sign and symptom of temporomandibular disorders and missing posterior teeth were examined by ultrasonography. Bilateral ultrasonographic examinations were performed with a linear (B-scan) 7.5 MHz small-part transducer to register LCSDs of the masseter muscle on three different levels. Scans were made on relaxed and clenching condition. Three oral and maxillofacial radiologists measured at two sessions with a time interval of at least 5 minutes. Results : Variables such as ‘condition’ and ‘level’ had a significant effect on muscle measurements (p>0.05). There was no significant difference betwee‘sessions’(p>0.05) and ‘observers’(p>0.05). LCSDs on lower scan level were significantly thinner than those on upper and middle level. Those on clenching condition were significantly thicker than those on relaxed condition (p<0.05). The scanning level with the highest reproducibility was middle with clenching condition (ICC = 0.90, MSE = 0.55%). Conclusion : The data suggested that ultrasonography was a reliable method for measuring LSCD of masseter muscle in intra- and interobserver and middle scan level showed the most reliable data.

Alveolar bone grafting is an essential component of successful surgical rehabilitation in many common cleft deformities. Primary alveolar bone grafting is defined as alveolar bone grafting which takes place before eruption of the primary dentition or before 1 years of age. The major objective in primary alveolar bone grafting is to prevent significant maxillary segmental collapse and arch disturbances. If severe, this can make secondary rehabilitation difficult, costly, and protracted. Such early stabilization may eliminate or, at least, decrease the amount of orthodontic arch expansion required during the transitional dentition period. Furthermore, early obliteration of alveolus fistulae improves speech and dental hygiene. It is critical that abutting maxillary segmental alignment be achieved(generally when the patient is 8 to 10 months of age) before grafting. Otherwise, the amount of dissection necessary to develop mucosal flaps for bone graft coverage will be more extensive, thus risking increased scar formation with potential adverse effects on growth. We report a preliminary result of 4 cases of primary alveolar bone graft using rib bone, performed by limited dissection and onlay graft technique at 8 to 10 months of age. They showed satisfactory clinical results especially in terms of growth up to now.

Adult polycystic kidney disease(APKD) usually accompanies with renal and extrarenal manifestations and liver cysts are present in aproximately 30% of patients with APKD. Kidney cysts often accompany with hemorrhage, rupture, infection, however, liver cysts are usually asymptomatic and do not impair liver function. Rare complication of liver cysts in patient with APKD include portal hypertension with bleeding esophageal varices and hepatic failure with encephalopathy. But, in APKD patient, infection of liver cysts without infection of renal cysts is extremely rare. We report a case of infected liver cyst in a patient with APKD who has complained generalized abdominal pain and high fever which was confirmed by ultrasound and aspiration. The patient was treated successfully with repeated aspiration and systemic antibiotics.

One of the most important parameters for explosive welding is flyer velocity(??), which principally depends on momentum aparted from detonation of the explosive. And close dependency with other parameters such as dynamic angle(β), impact pressure(??), charge ratio(R), flyer thickness(??) and stand-off distance(d), should be taken accounts for welding design. This paper describes, as a result of experiment, some empirical equation related to relation between ?? and R. The value of ?? equals to ?? can be used on ordinary experiment, seems to be better accuracy than any other investigators.
