The purpose of this study is to contribute reference material that provides insight into innovative process management that increases R&D output in commercializing new products. A model of a process from research to commercialization with the cumulative profit and loss curve is put forward and hypotheses related to success and failure are developed at the stages up to product launch. Seventeen large projects that have resulted in successful product launches have been examined from the initial research stage to commercialization. Project duration, standardized cumulative R&D expenditures and research resource concentration are analyzed in terms of statistical method and patterns in cumulative profit and loss curves after product sales, as well as the reasons for and other aspects of success/failure are investigated and analyzed. Consequently, valuable information on future management tasks has been obtained such as: (1) project duration differs depending on market sectors, product types and presence/absenceof materials research (2) cumulative profit and loss curves can be categorized into four patterns (3) reasons for failure can be divided into technological and market problem categories and (4) these factors have an impact on product sales.

Interventional management for postoperative arterial bleeding in gastrointestinal surgery
Yozo Sato,Kiyoshi Matsueda,Marie Osawa,Yoshitaka Inaba,Yu Takahashi,Yosuke Inoue,Atsushi Oba,Yosuke Fukunaga,Yasuhiro Shimizu 소화기인터벤션의학회 2022 Gastrointestinal Intervention Vol.11 No.4
Postoperative arterial bleeding after gastrointestinal surgery is a potentially fatal complication. Transcatheter arterial embolization is considered the first-line treatment because of efficacy and less invasiveness despite the risk of organ infarction. With the recent advances in endovascular devices, stent-graft placement, which can preserve arterial flow, has been an alternative treatment option in patients with extrahepatic artery hemorrhage. Moreover, clinical outcomes of stent-graft placement for pseudoaneurysms in relative long term have been reported recently. Herein, we review the techniques and clinical outcomes for interventional management for postoperative arterial bleeding.
