A Human Computation Game(HCG) is designed to solve difficult problems that cannot be dealt with computers with a large number of individuals' voluntary participations. Most existing relative studies focus on building more efficient system for problem solving, or the individual cases on the development of certain HCGs. However, a game is fully completed by the players who play it. Therefore, additional research is needed to annalize the ludic elements of HCGs, which induce people to play them voluntarily. We studied the purposes, tasks, and the game mechanics of 31 HCGs, then suggested how to design more enjoyable HCGs.

In this study, the hydrophilic chemical grout using silanol (HCGS) was introduced to overcome the limitations of conventional epoxy resin which have been used for strengthening reinforced concrete (RC) structures. Then, flexural tests on the RC slabs strengthened by FRP sheets were conducted. Three slab specimens were tested in this study; a control specimen with no strengthening, and two specimens strengthened by a typical epoxy resin or HCGS, respectively, as a binder between the slabs and the FRP sheets. In addition, an analytical model was developed to evaluate the flexural behavior of strengthened slab members, considering the horizontal shear force at the interface between concrete slabs and FRP sheets. The analysis results obtained from the proposed model indicated that the strengthened specimens showed fully composite behavior before their flexural failure. Especially, the specimen strengthened by HCGS, which can overcome the limitations of conventional epoxy resin, showed a similar flexural performance with that strengthened by a conventional epoxy resin.
