Solution mechanism guide: implementing innovation within a research & development organization.

In order to create a culture more open to novel problem-solving mechanisms, NASA's Human Health and Performance Directorate (HH&P) created a strategic knowledge management tool that educates employees about innovative problem-solving techniques, the Solution Mechanism Guide (SMG). The SMG is a web-based, interactive guide that leverages existing and innovative problem-solving methods and presents this information as a unique user experience so that the employee is empowered to make the best decision about which problem-solving tool best meets their needs. By integrating new and innovative methods with existing problem solving tools, the SMG seamlessly introduces open innovation and collaboration concepts within HH&P to more effectively address human health and performance risks.

Clinical risk management approach for long-duration space missions.

Introduction: In the process of crewmember evaluation and certification for long-duration orbital missions, the International Space Station (ISS) Multilateral Space Medicine Board (MSMB) encounters a surprisingly wide spectrum of clinical problems. Some of these conditions are identified within the ISS Medical Standards as requiring special consideration, or as falling outside the consensus Medical Standards promulgated for the ISS program.

Methods: To assess the suitability for long-duration missions on ISS for individuals with medical problems that fall outside of standards or are otherwise of significant concern, the MSMB has developed a risk matrix approach to assess the risks to the individual, the mission, and the program.

Matrix isolation ESR and theoretical studies of metal phosphides.

The ZnP, (67)ZnP, CdP, (111)CdP, and (113)CdP radicals have been formed by laser ablation of the metal with GaP pressed into the metal surface, isolated in an inert neon matrix at 4.3 K and their electronic structure was established using electron spin resonance spectroscopy. The following magnetic parameters were determined experimentally for ZnP/(67)ZnP, g(⊥)=1.

International Space Station medical standards and certification for space flight participants.

Introduction: The medical community of the International Space Station (ISS) has developed joint medical standards and evaluation requirements for Space Flight Participants ("space tourists") which are used by the ISS medical certification board to determine medical eligibility of individuals other than professional astronauts (cosmonauts) for short-duration space flight to the ISS. These individuals are generally fare-paying passengers without operational responsibilities.

Material And Context: By means of this publication, the medical standards and evaluation requirements for the ISS Space Flight Participants are offered to the aerospace medicine and commercial spaceflight communities for reference purposes.

Community noise: health effects and management.

This commentary will reemphasize the importance of urban noise as a health problem and provide a practical approach toward implementing legislative controls. References and a short discussion of accepted ways to measure noise are included. Furthermore, a brief review of relationships between noise and the development of disease is discussed.

Age-related blood flow and capillary changes in the rat utricular macula: a quantitative stereological and microsphere study.

Vascular change may contribute to age-related vestibular dysfunction. Previously, we reported a significant age-related decrease in blood flow (BF) and mean capillary diameter (D(cap)) in the rat posterior canal crista. The purpose of this study was to examine an otolith organ, the utricle, for similar changes.
