The study showed a different diurnal pattern of IOP under microgravity compared with that on ground. This result suggests that gravity and subsequent body fluid shift is one of the determining factors of IOP diurnal variation.
In this study, we simulated space flight of the nematode, Caenorhabditis elegans, on the ground and examined how it is affected by space radiation and G-forces. We simulated G-forces during launch in a gravity acceleration laboratory device in order to identify and isolate the effects of the G-forces. Following this, we irradiated C. elegans with accelerated protons (MC-50 Cyclotron) and gamma rays (iR 222 machine) at the same physical dose. We calculated the expected radiation dose according to Reitz [1] and simulation programs (NASA AP8MIN [2], NASA AE8MAX [2], and CREAM86 [3]) for 1 month (dose rate: 6 × 10 −3 Gy; 2.8 × 10 −2 Gy), 6 months (dose rate: 36 × 10 −3 Gy; 16.8 × 10 −2 Gy), and 2 years (dose rate: 144 × 10 −3 Gy; 67.2 × 10 −2 Gy) of space flight. There have been several trials that aimed to take C. elegans into orbit on US space shuttle missions including a mission on the shuttle Columbia. In this study, we simulated longer duration space flights and performed a whole-genome microarray analysis to observe phenotype variations whereas most such experiments were carried out during short duration space flights and focused on mutations and genotypic variations. We expect that the results of this study will be useful to predict the effects of long-term exposure of space radiation on living organisms.
This storytelling course will bring, in meaningful terms, insightful concepts, methods and tools that are used in the air and space domains. HCI for complex engineered systems challenges conventional HCI solutions to propose new kinds of approaches that turn out to be very useful for solving HCI complex problems. Participants will design devices usable on Earth using accumulated knowledge and tips from aerospace experience. Creativity, in the sense of synthesis and integration, and design thinking will be at the center of this course, where participants will learn how to state and solve a complex design problem, and deliver the resulting product.
We analyzed the result of sensory evaluation for the 10 items of Korean Space Foods performed by Korean astronaut in ISS. Although there were low score items because of the individual preference difference, Most items received the high score. Also, we can confirm the possibility of the internationalization of the Korean Space Foods because international astronauts gave the high valuation. we should develop the various space foods and food package which are easy to use in space for the human exploration in the future.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
