The 4th FTRA International Conference on Information Technology Convergence and Services (ITCS-12) will be held in Gwangju, Korea on September 6 - 8, 2012.
The ITCS-12 will be the most comprehensive conference focused on the various aspects of advances in information technology convergence, applications, and services.
The ITCS-12 will provide an opportunity for academic and industry professionals to discuss the latest issues and progress in the area of ITCS. In addition, the conference will publish high quality papers which are closely related to the various theories, modeling, and practical applications in ITCS. Furthermore, we expect that the conference and its publications will be a trigger for further related research and technology improvements in this important subject.
The ITCS-12 is the next event in a series of highly successful International Conference on Information Technology Convergence and Services(ITCS-11), previously held in Gwangju, Korea on October, 2011.

The philosophy of Lesson Study in Japan-teacher ownership, teacher professionalism, student learning-focused dialogue, teacher collaboration, and teacher professional community-has attracted educators and researchers worldwide. However, Lesson Study does not have the same meaning as its original Japanese expression Jugyou Kenkyuu, a combination of two Japanese words-Jugyou meaning instruction or lesson(s) and Kenkyuu meaning study or research. To bridge the gap between Jugyou Kenkyuu and Lesson Study and therefore maximize the potential of Lesson Study in the world, this edited volume provides two "mirrors" for those who wish to reflect on and implement Lesson Study within their own contexts. One section discusses how Lesson Study is utilized in Japanese teacher education and how this system reproduces the very culture of Lesson Study. The other section addresses case studies showcasing Lesson Study implementation in several countries such as the United States, Germany, Norway, Peru, and Uganda and discusses the opportunities and challenges that arise when Lesson Study-based teacher education expands beyond Japan to the rest of the world. This book will appeal to anyone interested in learning about Lesson Study.

This edited volume showcases work from the emerging field of design-based research (DBR) within social studies education and explores the unique challenges and opportunities that arise when applying the approach in classrooms. Usually associated with STEM fields, DBR's unique ability to generate practical theories of learning and to engineer theory-driven improvements to practice holds meaningful potential for the social studies. Each chapter describes a different DBR study, exploring the affordances and dilemmas of the approach. Chapters cover such topics as iterative design, using and producing theory, collaborating with educators, and the ways that DBR attends to historical, political, and social context.

Survival Analysis Using S: Analysis of Time-to-Event Data is designed as a text for a one-semester or one-quarter course in survival analysis for upper-level or graduate students in statistics, biostatistics, and epidemiology. Prerequisites are a standard pre-calculus first course in probability and statistics, and a course in applied linear regression models. No prior knowledge of S or R is assumed. A wide choice of exercises is included, some intended for more advanced students with a first course in mathematical statistics.

The authors emphasize parametric log-linear models, while also detailing nonparametric procedures along with model building and data diagnostics. Medical and public health researchers will find the discussion of cut point analysis with bootstrap validation, competing risks and the cumulative incidence estimator, and the analysis of left-truncated and right-censored data invaluable. The bootstrap procedure checks robustness of cut point analysis and determines cut point(s).

In a chapter written by Stephen Portnoy, censored regression quantiles - a new nonparametric regression methodology (2003) - is developed to identify important forms of population heterogeneity and to detect departures from traditional Cox models. By generalizing the Kaplan-Meier estimator to regression models for conditional quantiles, this methods provides a valuable complement to traditional Cox proportional hazards approaches.
