Editorial introduction

Abstract

This special issue deals with research presented at the biannual SPSD conference held in Seoul, South Korea in 2017. Specifically, about half of the presentations (total 68) were submitted in full length, aiming for official publication in IRSPSD and from these, this issue was initially based on nine papers. Five papers were finally accepted and comprise this special issue.A common characteristic of the five accepted papers is that they all did case studies through historical approaches, simulation, experiments and observations according to which the past and present and the processes of realworld projects were examined. This might possibly provide proof for the validity and necessity of such an innovative perspective if one intends in-depth analysis of practical projects and cases.
