LINICALLY SIGNIFICANT DEPRESsion affects 15% to 20% of elderly individuals in the United States. 1,2 Older individuals are less likely than younger adults to have major depression 3 but have comparable or higher rates of less severe depressive disorders such as dysthymia and minor depression. Dysthymia is a chronic depressive syndrome persisting for at least 2 years. 4 According to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) Appendix of Criteria Sets and Axes Provided for Further Study, minor depression is depressed mood and/or significant loss of interest, plus 1 to 3 other depressive symptoms present nearly every day for at least 2 weeks, occurring in the absence of dysthymia. 4(pp719-721) Minor depression and dysthymia both lead to significant disability. 5,6 Accumulating evidence from primary care set-

The use of a modern technological system requires a good engineering approach, optimized operations, and proper maintenance in order to keep the system in an optimal state. Predictive maintenance focuses on the organization of maintenance actions according to the actual health state of the system, aiming at giving a precise indication of when a maintenance intervention will be necessary. Predictive maintenance is normally implemented by means of specialized computational systems that incorporate one of several models to fulfil diagnostics and prognostics tasks. As complexity of technological systems increases over time, single-model approaches hardly fulfil all functions and objectives for predictive maintenance systems. It is increasingly common to find research studies that combine different models in multi-model approaches to overcome complexity of predictive maintenance tasks, considering the advantages and disadvantages of each single model and trying to combine the best of them. These multi-model approaches have not been extensively addressed by previous review studies on predictive maintenance. Besides, many of the possible combinations for multi-model approaches remain unexplored in predictive maintenance applications; this offers a vast field of opportunities when architecting new predictive maintenance systems. This systematic survey aims at presenting the current trends in diagnostics and prognostics giving special attention to multi-model approaches and summarizing the current challenges and research opportunities.

Researchers have identified as effective and worthy of broader dissemination a variety of intervention strategies to promote physical activity among older adults. This paper reports results of a community-organizing approach to disseminating evidencebased interventions in a sustainable way: The Southeast Seattle Senior Physical Activity Network (SESPAN). SESPAN was implemented in Southeast Seattle, a group of multicultural neighborhoods extending 8 miles southeast of downtown Seattle, with a population of 56,469 in 2000, with 12% (7,041) aged 65 and older. The SESPAN organizing strategy involved networking to: (1) make connections between two or more community organizations to create new senior physical activity programs; and (2) build coalitions of community groups and organizations to assist in making larger scale environmental and policy changes to increase senior physical activity. The SESPAN evaluation used an uncontrolled prospective design focusing on sustainable community changes, including new or modified programs, policies, and practices. Networking among organizations led to the creation of 16 ongoing exercise classes and walking groups, serving approximately 200 older adults in previously underserved Southeast Seattle communities. In addition, the project's health coalition is sustaining current activities and generating new programs and environmental changes. The success of the SESPAN organizing model depended on identifying and involving champions in partner organizations who provided support and resources for implementing programs.

The interest of functionally graded adhesives (FGA) is growing as it is a mean to increase a bonded joint strength without any modification of the initial design of the adherends. The behaviour of bonded joints with variable adhesive properties along the overlap can be predicted with a potentially time-costly Finite Element (FE) analysis. Dedicated numerical procedures and design tools for FGA bonded joints would increase. The objective of this paper is to offer a mesh-free method for the analysis of functionally graded joints. The technique is based on the macro-element (ME) method and Taylor expansion in power series (TEPS) are used to approach the shape functions of the ME. The method has been developed so far for 1D-bar and 1D-beam kinematics frameworks. This mesh-free_method and a Finite-Element analysis give similar results.

This article describes a community organizing approach to promoting physical activity among underserved older adults in southeast Seattle: the Southeast Senior Physical Activity Network (SESPAN). The organizing strategy involves networking with a variety of community-based organizations, with two broad objectives: (a) program objective-to make connections between two (or more) community-based organizations to create senior physical activity programs where none existed before; and (b) coalition objective-to build a broader network or coalition of groups and organizations to assist in making larger scale environmental and policy changes. Networking among organizations led to the creation of a number of potentially sustainable walking and exercise programs that are reaching previously underserved communities within Southeast Seattle. In addition, a major community event led to the establishment of a health coalition that has the potential to continue to generate new broad-based programs and larger scale environmental changes.
