Recently, many organizations such as, including government, railroad operational, railroad facilities managemental and research authorities have made a lot of efforts to identify and prevent hazards from leading to accidents and solve them all over the railroad industry. Railroad total safety technology development project conducted as one of national R&D projects has established business formation structure based on system engineering as an effort to define and give a solution to facing problems in the field of railroad. This paper is building procedures to verify the outcomes derived from this project. The verification process is the one for verifying the outcome produced in the final stage of the project or during the project. It makes sure that the system is satisfying the system requirements through verification of the outcomes produced after conducting the project for verification. We"ve made verification plan for technically reasonable verification using verification process developed through this research, and established master verification plan in the level of 15 detailed projects for interim and final outcomes produced.

As technologies are developed and systems are complicated, hazards embedded in the system are also increasing. proving safety and managing the safetyis more scientific and organizational domain so that safety management system is pursuing to be activeformation detecting the factors of hazard and managing them beyond passiveway. In the future, in order to establish and manage national safety management system, it is important to have effective system and manage it and also more important that all the people related to target system has to change their recognition and to playroles in it. Many railway safety measures reduce railway fatalities into half for last 10 years. But more improvement in railway safety is required to meet the social need after railway fire accident in Daegue. After the Daegue subway train fire accident, the Korean government has been trying to prepare a nation-wide railway safety program, a safety organization, and a Safety Act. To construct a nation-wide railway safety management program, system architecture was established.

To establish the national railway safety system, the railway total safety technology development project has been promoted by Ministry of Construction and Transportation (MOCT) since August 2004. The project is mainly focused on the prevention of a critical railway accident and the reduction of accident/mortality rate. To achieve its goal effectively, the project is composed of 15 sub-projects each of which can be categorized into three different technological area. This work deals with the verification results for the outcomes of the sub-projects carried out at the 2nd year of the project. A new verification procedure is developed and applied to the project based on the system engineering. Three criterions - The suitability of the realization of a function, the suitability of a physical structure, the suitability of a design analysis report - are used for the verifications. The verification results are investigated by calculating standard deviations of scores of each results.

To establish the national railway safety system, the railway total safety technology development project has been promoted by Ministry of Construction and Transportation (MOCT) since August 2004. The project has producted successful results in many areas of railway safety, however, it is required that the research field should be re-examined to meet the aim of the project. To do that, the precedence of the investment of research resources should be reviewed and determined. The risk of serious railway accidents such as train collision, derailment and level crossing accidents are estimated. From the estimation result and the statistics on the railway accidents over fast few years, the risk factors of railway accidents can be calculated.

Purpose: Pancreaticoduodenectomy for mass-like lesions that are suspicious of malignancy sometimes reveals only nonneoplastic disease, especially in those cases where adequate tissues for biopsy are unavailable. In this study, we evaluated the outcomes and quality of life (QOL) after pancreaticoduodenectomy for treating nonneoplastic disease. Methods: The clinical data of 28 patients who underwent pancreaticoduodenectomy for nonneoplatic disease and trauma from Jan. 1992 to Feb. 2006 were reviewed retrospectively. The QOL was evaluated using the FACT-Hep questionnaire. The patients who underwent laparoscopic cholecystectomy for benign gallbladder disease were utilized as the control group. Results: 13.8% (28/203) of all the pancreaticoduodenectomized patients had nonneoplatic disease and trauma. Male patients were predominant (25/28) and all the trauma patients were male. The mean age was 48 (23∼72) years old. The indications for surgery included lesions suspicious for malignancy (16 cases), pancreaticoduodenal artery aneurysm (1 case), and pancreatoduodenal injury (11 cases). The histologic findings of the nonneoplastic lesions revealed benign inflammation of the bile duct (6 cases), chronic pancreatitis (8 cases), pancreatic pseudocyst (1 case), and fibrosis of the Ampulla of Vater (1 case). No surgical mortality occurred. However, the trauma patients group had higher morbidity (72.7% Vs 23.5%, respectively, P=0.01) and a longer hospital stay (68.0 days Vs 32.6 days, respectively, P=0.02) after surgery compared to the nonneoplastic disease patient group. The QOL of the patient who underwent pancreaticoduodenectomy for nonneoplatic disease was not different from that of the control group. Conclusion: Since pancreaticoduodenectomy for nonneoplastic disease was safe and the QOL of the patients was acceptable, it should be performed more often when malignancies can not be excluded from the differential diagnosis.
