In this study, the concept of safety impact assessment to achieve `Design-for-Safety` in design phase is introduced. For this purpose, safety impact assessment model was devised and a methodology using the risk-based safety impact assessment approach for NATM of tunnel projects is suggested. The suggested methodology includes safety information survey, classification of safety impact factors caused by design and construction, and quantitative estimation of magnitude and frequency of safety impact factors. A real-world case study on the safety impact assessment of a tunnel construction project is also provided in the paper.

N/A Background/Aims: In gastrointestinal cancers, the protruded type is known to be lesser aggressive than non-protruded type. The purpose of this study is to confirm the biological difference of aggressiveness between protruded and non-protruded type of gastrointestinal cancer. Methods: Three hundred sixty one cases of advanced gastric cancers(196 cases of early gastric cancers and 279 cases of colorectal cancers) which were operated at Asan Medical Center from June 1st 1989 to December 3lth 1992, were analyzed. Statistica] analysis was performed in clinical parameters that may be related to prognosis in early and advanced gastric cancer and colorectal cancer between the protruded and non-protruded type. Results: In advanced gastric carcinoma, there were significant differences in age, histological differentiation and lymph node positivity between two groups(p0.05). In colorectal carcinoma, there were significant differences in fixation, Astler- Coller stage, lymph node positivity and number of positive lymph node between two groups(pC 0.05). In advanced gastric cancer and colorectal cancer, the protruded type was less aggressive than non-protruded type that is the same as previous other studies. The protruded type showed less aggressiveness than non-protruded type in early gastric cancer. Conclusions: The morphological characteristics of gastrointestinal carcinoma seemed to affect the biological characteristics of differentiation or lymph node metastasis.
