Redefining tactical operations for MER using cloud computing
The Mars Exploration Rover Mission (MER) includes the twin rovers, Spirit and Opportunity, which have been performing geological research and surface exploration since early 2004. The rovers' durability well beyond their original prime mission (90 sols or Martian days) has allowed them to be a valuable platform for scientific research for well over 2000 sols, but as a by-product it has produced new challenges in providing efficient and cost-effective tactical operational planning. ***
Cloud Computing for Mission Design and Operations
The space mission design and operations community already recognizes the value of cloud computing and virtualization. However, natural and valid concerns, like security, privacy, up-time, and vendor lock-in, have prevented a more widespread and expedited adoption into official workflows. In the interest of alleviating these concerns, we propose a series of guidelines for internally deploying a resource-oriented hub of data and algorithms. These guidelines provide a roadmap for implementing an architecture inspired in the cloud computing model: associative, elastic, semantical, interconnected, and adaptive. The architecture can be summarized as exposing data and algorithms as resource-oriented Web services, coordinated via messaging, and running on virtual machines; it is simple, and based on widely adopted standards, protocols, and tools. The architecture may help reduce common sources of complexity intrinsic to data-driven, collaborative interactions and, most importantly, it may provide the means for teams and agencies to evaluate the cloud computing model in their specific context, with minimal infrastructure changes, and before committing to a specific cloud services provider.
Research on health and oral health status of elderly living alone compared to elderly living with their families - based on the data (2014) from the 6th two-year Korea national health and nutrition examination survey -
Objectives: I examined the health and oral health status of elderly people living alone compared to elderly people living with their families by using data (2014) from the 6th Two-Year Korea National Health and Nutrition Examination Survey. Methods: Among 1,454 health survey respondents aged 65 years and over who participated in the 6th Two-Year Korea National Health and Nutrition Examination Survey conducted in 2014, 311 were elderly people living alone and 1,143 were elderly people living with their families. Results: In terms of socio-demographic characteristics, the percentage of elderly people living alone was high especially in women and when the subjects’ age, education level, and income level were low. In terms of oral health status, the percentage of elderly people living alone was high when elderly people thought that their subjectively viewed health was poor and the frequency of drinking and exercise was low. In terms of oral health status, the percentage of elderly people living alone was high among elderly people who did not have good oral health in their subjective view and did not get oral examinations for a year and had a lot of difficulty chewing. Conclusions: Family support or additional social support for elderly people who live alone should be considered to promote the healthy lives of elderly people.
