The problems like exceeding estimated cost, late due-date, expensive maintenance, insuffiency of experts and low productivity are becoming emphasized related with the software development. In order to overcome these problems and to develop the highly qualified software within the limited resources, a project management tool is used. The purpose of this study is to develop a conceptual model of the project management system which can plan, analyze and control the software development projects effectively. The model is constructed with plan and track management system, cost management system and operation management system for the efficient project management. It is named by LSD-PMS : Large-scale Software Development Project Management System. We reviewed 5 cases of project management. LSD-PMS is evaluated and reviewed by the project managers in the field. It is proved that LSD-PMS is a tool which can help project managers develop software successfully given budget and time schedule. In the future, this system should be further developed as an integrated model with system implementation tools such as CASE products.

We have experienced a patient, 16 year-old male, with ventricular septal defect with tricuspid recur- gitation due to blunt chest trauma. He suffered from congestive heart failure after the trauma. Echocardiogram and cardiac catheterization revealed left to right shunt at the ventricular level (muscu- far portion of interventricular septum) and tricuspid regurgitation. At the time of the operation, marked systolic thrill was palpable over the rlght ventricle near the apex and a chorda tendina was seen sharply ruptured just near the medial papillary muscle. We repaired the ventricular septal defect with a Dacron patch and chordal reconstruction with autologous pericardium. The postoperative course was uneventful and the patient was discharged in good condition.

Depending on the degree of exocrine pancreatic insufficiency, there are inconsistent values in the serum trypsin-like immunoreactivity (TLI), hematology, and serology. To determine the correlation between those values and complete pancreatic insufficiency, 10 pancreatectomized dogs as the treated group and 10 sham operation dogs as control group were used. The entire treated group showed significant decrease in serum TLI level from 2.63$\pm$0.20 ng/ml (day 0) to 1.81$\pm$0.43 ng/ml at day 1 after the pancreatectomy (p<0.05) and the decline maintained till the end of the experiment. Blood glucose level gradually increased, but albumin level showed significant decrease (p<0.05) at day 1 and maintained the decline. Three clinical signs were observed such as depression, vomiting, and diarrhea. The entire treated group showed diarrhea throughout the experiment, but depression and vomiting were gradually diminished. The activity of serum alkaline phosphatase in the treated group increased till day 2 then decreased, on the other hand, control group showed continuous increase till day 4, and then decreased. Only experimental group showed the increased alanine aminotransferase activity at day 1. Serum lipase activity in the treated group jumped up at day 1 and then dropped down, which was even lower than the control. Regarding serum amlyase activity gradually decreased. According to these results, the assay of trypsin-like immunoreactivity showed the consistent result, so it suggests that TLI is an useful tool to determine the pancreatic exocrine function and possible diagnosis of exocrine pancreatic insufficiency compared to the simple assay of plasma amylase and lipase.
