We propose a practical fiber optic probe, which uses a fiber patch cord and an anti-reflection coated ball lens for dental optical coherence tomography imaging. The probe has benefits of compactness, long working distance as well as comfort and oral hygiene for patients. With the proposed probe, the image of a human tooth, having enamel, dentin, dento-enamel junction and crack, was successively obtained. © 2011 AOS.

Background: In bioinformatics projects, scientific workflow systems are widely used to manage computational procedures. Full-featured workflow systems have been proposed to fulfil the demand for workflow management. However, such systems tend to be over-weighted for actual bioinformatics practices. We realize that quick deployment of cutting-edge software implementing advanced algorithms and data formats, and continuous adaptation to changes in computational resources and the environment are often prioritized in scientific workflow management. These features have a greater affinity with the agile software development method through iterative development phases after trial and error. Here, we show the application of a scientific workflow system Pwrake to bioinformatics workflows. Pwrake is a parallel workflow extension of Ruby's standard build tool Rake, the flexibility of which has been demonstrated in the astronomy domain. Therefore, we hypothesize that Pwrake also has advantages in actual bioinformatics workflows. Findings. We implemented the Pwrake workflows to process next generation sequencing data using the Genomic Analysis Toolkit (GATK) and Dindel. GATK and Dindel workflows are typical examples of sequential and parallel workflows, respectively. We found that in practice, actual scientific workflow development iterates over two phases, the workflow definition phase and the parameter adjustment phase. We introduced separate workflow definitions to help focus on each of the two developmental phases, as well as helper methods to simplify the descriptions. This approach increased iterative development efficiency. Moreover, we implemented combined workflows to demonstrate modularity of the GATK and Dindel workflows. Conclusions: Pwrake enables agile management of scientific workflows in the bioinformatics domain. The internal domain specific language design built on Ruby gives the flexibility of rakefiles for writing scientific workflows. Furthermore, readability

Organizations have been relying on collaboration for productivity improvement and knowledge sharing. The first step to foster collaboration in organizations is to make it explicit. With this aim, the Collaboration Maturity Model (CollabMM) was proposed and evaluated. The lessons learned during model applications in previous work pointed out the need to review both the model and its evaluation instruments. A literature review also showed some improvement opportunities. Therefore, the objective of this work is to develop a roadmap to highlight the main opportunities of evolution in CollabMM. These opportunities will compose our research agenda in this topic and guide future work.

IEEE International Conference on Micro Electro Mechanical Systems

This paper presents a PDMS micro through-hole molding method by simple soft lithography process in which the surface of a master mold and a substrate is treated by atmospheric CH 4 /He RF plasma to feature hydrophobic property on the surface. Rectangular and circular-shaped PDMS micro through-hole layers are made by the proposed fabrication method. As one of the applications of the PDMS micro through-hole layer for multi-layered systems, a radial concentration gradient generator including a micro through-hole layer is constructed and its performance is tested. The micro through-holes fabricated by the proposed method are well-defined. The concentration gradients measured in radial directions are in a similar level. Also, the tearing problem, which is often happened in spin-coating and lift-off molding methods, is not observed during the fabrication process of the PDMS micro through-holes. Therefore, we believe that the proposed fabrication method contributes to improve the technology for PDMS through-hole fabrication.

Collaborative techniques for business process design are generally supported by groupware tools that allow process actors to interact collecting their knowledge about the activities performed. Despite success reports, challenges are still observed due to the complexity of this task. We propose to gather benefits of interviews, collaboration and visual methods in eliciting business processes in order to deal with problems identified in literature. We present an approach based on a collaborative mobile application which analysts should use while interviewing process stakeholders. The information is collected through a simple BPMN diagram through which they exchange information and build parts of the models.

We research the multimedia information hiding (MIH) which is a technology to overlay digital information on multimedia contents such as picture, sound, document, etc. As application to disaster management of MIH, we have developed a new technology called "PAIH" (Public Address information Hiding) which is a technology to overlay information such as position or destination on siren sound of urgent vehicles. Siren sound is allowed to degrade of sound quality, but PAIH is required to decode correct information from siren sound with pitch shift (Doppler effect) or under noisy environment.
