Book Description
This summary provides an overall perspective of progress throughout all contracts within two Canadian Forces soldier modernization programs: the Integrative Protective Clothing & Equipment (IPCE) project and the Clothe the Soldier (CTS) Project. Each of these projects is described briefly and relevant outcomes are identified. The first three phases concerned a contract on the research & development of an Advanced Personal Load Carriage Measurement System. Work carried out included a literature review, development of load carriage measurement systems, design & validation of a load carriage simulator, evaluation of pack-based load carriage systems & sub-systems, and development of test protocols. The objective of phase IV, the IPCE project, was to improve measurement components and to develop a further understanding of specific factors that affect load carriage ability. Topics covered in this phase include development of a biomechanical model for load carriage assessment, parametric analysis of advanced load carriage systems, and analysis of human responses to load location in a backpack.

Book Description
The purpose of this study was to develop a personal load carriage system design tool that should enable designers to input pack parameters and receive an objective measure of the pack's effectiveness. Pack parameters of interest include dimensions, weight, centre of gravity, and location of shoulder straps, waist belt, & lumbar pad. The objective evaluation consists of two body reaction forces known to relate to pack acceptability scores. Knowledge of the body reaction forces then aids in understanding of comfort and can enable comparison of potential prototypes. The study developed a statically determinate model of the pack/person interface to include the design parameters of interest and the evaluated body reaction forces. To validate the effectiveness of the design tool, six packs were tested on an instrumented human-form jig. Results show the capability of the design tool to predict outputs close to measured values. Limitations of the developed tool are discussed.

Book Description
The purpose of this study was to determine the effect of varying the centre of gravity of the load on physiological, biomechanical, & subjective factors of experienced soldiers. A secondary purpose was to examine the relationship of these factors to a standardized load carriage simulator test. In the study, 22 soldiers marched on a treadmill for 15 minutes carrying a modified backpack consisting of a pack frame & a movable load box containing 36 kilograms. In addition, a load carriage vest was used to examine a balanced load distribution. Results are presented with regard to: physiological measures collected using oxygen consumption & heart rate; biomechanical measures collected from video images of gait to calculate trunk & body lean; subjective measures of pressure points using a body scan image; and general assessments of each system & overall ranking.

Book Description
A comprehensive measurement system for load carriage evaluation has been developed consisting of human input with respect to comfort, features, & fit, as well as a standardized measurement system using a computer-controlled load carriage (LC) simulator. The purpose of the study described in this report was to validate the measurement systems used in the LC simulator under both static & dynamic conditions, and to conduct a sensitivity analysis of the biomechanical model used to evaluate shoulder & lumbar forces. To accomplish the first objective, independent measurement strategies were formed for each of the simulator output measures. Results are presented from the static & dynamic test measurements from the LC simulator's strap force transducers, pressure sensing system, and pack displacement sensors. For the second objective, a standardized jig for shoulder strap testing was developed where strap forces, pressures, shoulder geometry, and pack conditions could be evaluated independently. Results are presented from shoulder/strap friction calculations using two methods. The appendix contains a copy of the LC simulator test protocols.

Book Description
The proper design of personal load carriage systems may be critical not only for soldier comfort, but also for soldier mobility and performance on the battlefield. Evaluation of soldier personal load carriage systems typically involves the conduct of human-based lab and field trials that can be both time-consuming and costly to conduct. Field testing usually requires multiple system prototypes of a given design iteration, with their development cost often limiting the number of design iterations tested. Human-based trials also rely on subjective opinion for system assessment. While the opinions of the ultimate users have face validity, and bias and error can be controlled in such trials, it is also desirable to have objective load carriage assessment methods and analysis tools that permit rapid analysis, design iteration and evaluation. Canada has developed biomechanical assessment and analytical tools to supplement human-based load carriage system assessment methods. This suite of tools permits efficient objective evaluation of important biomechanical aspects of load-bearing webbing, vests, packs and their components, thus contributing to early system assessment and a rapid iterative design process. This paper will introduce each of the assessment and analytical tools, their rationale, the objective measures available and the recommended performance criteria for acceptable military load carriage systems. Separate papers in these proceedings will provide the details of validation and utility of the tools that have been developed by Canada.

Book Description
Many NATO nations have soldier modernization programmes that aim to equip soldiers with fully-integrated state-of-the-art technologies that will enhance the five NATO soldier capability areas: lethality, protection, mobility, sustainability, and command and control. Military load carriage systems (LCS), which include clothing and personal areas. In particular, LCS are critical to soldier mobility and sustainability, and ultimately, to soldier performance and survival on the battlefield.

Book Description
Children are already learning at birth, and they develop and learn at a rapid pace in their early years. This provides a critical foundation for lifelong progress, and the adults who provide for the care and the education of young children bear a great responsibility for their health, development, and learning. Despite the fact that they share the same objective - to nurture young children and secure their future success - the various practitioners who contribute to the care and the education of children from birth through age 8 are not acknowledged as a workforce unified by the common knowledge and competencies needed to do their jobs well. Transforming the Workforce for Children Birth Through Age 8 explores the science of child development, particularly looking at implications for the professionals who work with children. This report examines the current capacities and practices of the workforce, the settings in which they work, the policies and infrastructure that set qualifications and provide professional learning, and the government agencies and other funders who support and oversee these systems. This book then makes recommendations to improve the quality of professional practice and the practice environment for care and education professionals. These detailed recommendations create a blueprint for action that builds on a unifying foundation of child development and early learning, shared knowledge and competencies for care and education professionals, and principles for effective professional learning. Young children thrive and learn best when they have secure, positive relationships with adults who are knowledgeable about how to support their development and learning and are responsive to their individual progress. Transforming the Workforce for Children Birth Through Age 8 offers guidance on system changes to improve the quality of professional practice, specific actions to improve professional learning systems and workforce development, and research to continue to build the knowledge base in ways that will directly advance and inform future actions. The recommendations of this book provide an opportunity to improve the quality of the care and the education that children receive, and ultimately improve outcomes for children.
