To meet the challenges of ubiquitous computing, ambient technologies and an increasingly older population, researchers have been trying to break away from traditional modes of interaction. A history of studies over the past 30 years reported in this paper suggests that Gesture Controlled User Interfaces (GCUI) now provide realistic and affordable opportunities, which may be appropriate for older and disabled people. We have developed a GCUI prototype application, called Open Gesture, to help users carry out everyday activities such as making phone calls, controlling their television and performing mathematical calculations. Open Gesture uses simple hand gestures to perform a diverse range of tasks via a television interface. This paper describes Open Gesture and reports its usability evaluation. We conclude that this inclusive technology offers some potential to improve the independence and quality of life of older and disabled users along with general users, although there remain significant challenges to be overcome.

Adipose-derived stem and regenerative cells (ADRCs), concentrated from autologous fat tissue, have the ability to differentiate into various specific cell types including tenocytes. In this retrospective study, clinical data are presented from 83 horses with 176 suspensory ligament injuries, treated with ADRCs, given a strictly enforced standardized rehabilitation program, and followed up for at least one year after returning to work. Assessment for a successful outcome was return to full work (RFW) at a previous or higher level of performance for one year or more without re-injury. RFW numbers were 84.6% for horses with fore-limb ligament injuries and 82.1% for horses with hind-limb injuries. RFW outcomes were slightly better in cases with proximal suspensory ligament desmitis (86.7%) compared to horses with lesions of the body and branches. The ADRC injection procedure was well tolerated;no treatment-related adverse events, including injection flares, were detected in any of the 83 horses. The demonstrated long term stability of healed lesions strongly supports the therapeutic use of regenerative cells extracted from adipose tissue for treatment of acute and chronic, fore- and hind-limb suspensory ligament injuries in horses of various athletic sport disciplines.

Scrum—Agile programming—is getting more attention in Software Engineering practices. Many software projects began with small and were not certain about the requirements until projects have completed;this makes Scrum more appropriate than other development methodologies. This paper reintroduced Scrum from qualitative perspective by applying ethnography and in-depth interview to two different types of project teams to articulate what the success factors are for running Scrum framework. It clearly demonstrated how qualitative research could help in disclosing the essence of facts during the Scrum adaptation in depth. It also articulated how these successful factors mutually affect to one another from System Dynamics perspective and to give further recommendations to Scrum teams and those who tend to apply Scrum development methodology.

Today’s enterprises have accumulated vast amount of data and keep exploding by business activities. These datasets may contain potential undiscovered business strategies as a key basis of competition;underpin new waves of productivity growth, innovation, and consumer surplus. Data analysis is crucial in making managerial decisions. Although there are many Business Intelligence (BI) software of commercial and open source, but serving statistical purpose as exuberant as GNU-R (R) is rare. R is a highly extensible language and environment for providing a variety of statistical and graphical features. In enterprise environment, the source data are stored in various forms such as files, database, and streaming data. Currently analysts conduct data analysis in offline mode using statistical software. The offline mode means analysts 1) extract the desired data;2) store extracted data into files;3) manipulate software;4) draw analytical results;5) generate the inferences. Automating the statistical procedures by directly pulling source data will make critical decision sooner and less costly. It is a common practice that enterprise adopts Service-Oriented Architecture (SOA) to achieve its operation excellence. Since the business applications populate the source data during the operation processes, pulling the source data directly under SOA is the most effective way of data analysis. This paper demonstrates how service-oriented statistics engine was developed and how such a system benefits the business decision-making.

The Upper Lillooet River Hydroelectric Project （ULHP） is a run-of-river power generation scheme located near Pemberton, British Columbia, Canada, consisting of two separate hydroelectric facilities （HEFs） with a combined capacity of 106.7 MW. These HEFs are owned by the Upper Lillooet River Power Limited Partnership and the Boulder Creek Power Limited Partnership, and civil and tunnel construction was completed by CRT-ebc. The Upper Lillooet River HEF includes the excavation ofa 6 m wide by 5.5 m high and approximately 2500 m long tunnel along the Upper Lillooet River Valley. The project is in a moun- tainous area; severe restrictions imposed by weather conditions and the presence of sensitive wildlife species constrained the site operations in order to limit environmental impacts. The site is adjacent to the Mount Meager Volcanic Complex, the most recently active volcano in Western Canada. Tunneling conditions were very challenging, including a section through deposits associated with the most recent eruption from Mount Meager Volcanic Complex （-2360 years before the present）. This tunnel section included welded breccia and unconsolidated deposits composed of loose pumice, organics （that represent an old forest floor）, and till, before entering the underlying tonalite bedrock. The construction of this section of the tunnel required cover grouting, umbrella support, and excavation with a combination of road header, hydraulic hammer, and drilling-and-blasting method. This paper provides an overview of the project, a summary of the key design and construction schedule challenges, and a description of the successful excavation of the tunnel through deposits associated with the recent volcanic activity.
