Populating information-rich online environments through crowdsourcing is increasingly becoming popular. One approach to motivate participation is via games. That is, a crowdsourcing game offers entertainment while generating useful outputs as byproducts of gameplay. A gap in current research is that actual usage patterns of crowdsourcing games have not been investigated thoroughly. We thus compare content creation patterns in a game for crowdsourcing mobile content against a non-game version. Our analysis of 3,323 contributions in both apps reveal 10 categories including those that conform to the traditional notion of mobile content created to describe locations of interest, and those that are social in nature. We contend that both types of content are potentially useful as they meet different needs. Further, the distribution of categories varied across the apps suggests that games shape behavior differently from non-game-based approaches to crowdsourcing.

In the semiconductor fabrication, particle contamination is wide-spread and one of major causes to yield loss. Extensive testing has revealed that even careful handling of wafers during processing may cause photo-resist materials to flake off wafer edges. So, to remove the photo-resist at the outer 5mm of wafers, UV(Ultraviolet) rays are exposed. WEE (Wafer Edge Exposure) process station is the system that exposes the wafer edge as prespecified by controlling the positioning mechanism and maintaining the light intensity level In this work, WEE process station has been designed so as to significantly lower the amount of particle contamination which occurs even during the most r...

The purpose of the study was to verify the clinical effect of Computer-based cognitive rehabilitation program for Children for recovering the visual perception and ADL ability in intellectual disability. For this purpose, 3 intellectual disabilities with visual perception and ADL disorders participated in a clinical experiment to verify the effect of Computer-based cognitive rehabilitation program. They all have 5 common conditions in intellectual disability for objective experimental result. All participant were evaluated with Korean-Development Test of Visual Perception-2(K-DTVP-2), Wee Functional Independence Measure(Wee-FIM) before and after the planned intervention sessions. All intervensions were intensively carried out for 20weeks, 1 time a week. The result were as follows. K-DTVP and Wee-FIM scores were improved significantly compared to pre-intervention. Further studies are needed to verify the effect on various group and lots of participants.
