The Safety of Walking Space for the Elderly People Living in Communities in Beijing, China

According to the sixth national census [1], as of November 1, 2010, China’s elderly people over 60 years of age reached 178 million, accounting for 13.26% of the total population. Of which over the age of 65 for the elderly people reached 119 million, accounting for 8.87% of the total population. China has become the only country with a world elderly population of over 100 million. And it is predicted that this figure is growing at an annual rate of 3%. By 2025, the elderly will account for 19.34% of the total population. To 2040, the elderly will account for 27.8% of the total population.

Aging in place is an important option for the elderly people in China due to the influence of Chinese tradition. Communities are the environment where the elderly people spend most of their time. The walking space in the communities is important for the safety of the elderly people.

The research studied the safety of walking space of the elderly people living in the communities by using the data collected by observation, interviews and questionnaire surveys. The results identified three types of risks which are caused by pavements, public facilities and surrounding environment based on the qualitative analysis. The results of the quantitative analysis by using SPSS 19.0 found that the risks are highest in surrounding environment than the pavements and public facilities. The public facilities have the lowest risks. The findings of this study provide knowledge for future transformation of the old communities and the planning of new communities.

Incorporation of High-Altitude Balloon Experiment in High School Science Classrooms

High-altitude balloon is a balloon, filled usually with helium or hydrogen that ascends into an area called “near space” or stratosphere. The most common type of high-altitude balloons are weather balloons. Other purposes include use as a platform for experiments in the upper atmosphere. Modern balloons generally contain electronic equipment such as radio transmitters, cameras, or satellite navigation systems, such as GPS receivers. The mission of the High-Altitude Balloon Experiment (HABE) is to acquire supporting data, validate enabling technologies, and resolve critical acquisition, tracking, and pointing (ATP) and fire control issues in support of future space-based precision pointing experiments. The use of high-altitude balloons offers a relatively low-cost, low-vibration test platform, a recoverable and reusable payload, worldwide launch capability, and a 'near- space' emulation of the future space systems operational scenarios. More recently, several university...

Electron Spin and Proton Spin in the Hydrogen and Hydrogen-Like Atomic Systems

Read full paper at: http://www.scirp.org/journal/PaperInformation.aspx?PaperID=52202#.VIj7tMnQrzE Author(s) Stanisław Olszewski * Affiliation(s) Institute of Physical Chemistry, Polish Academy of Sciences, Warsaw, Poland . ABSTRACT The mechanical angular momentum and magnetic moment of the electron and proton spin have been calculated semiclassically with the aid of the uncertainty principle for energy and time. The spin effects of both kinds of the elementary particles can be expressed in terms of similar formulae. The quantization of the spin motion has been done on the basis of the old quantum theory. It gives a quantum number n = 1/2 as the index of the spin state acceptable for both the electron and proton ...

Fermented Brown Sugar Residue Prolongs the Caenorhabditis elegans Lifespan via DAF-16

Fermented brown sugar residue (FBSR) is generated in the course of purifying biomass ethanol from the yeast fermentation products of brown sugar. It contains abundant nutrition and is used in various industrial applications including as fertilizer and feed. Meanwhile, brown sugar has attracted attention as a health food and is thought to prevent cardiovascular diseases, hypertension, and brain stem diseases. Furthermore, polyphenol, contained in brown sugar, reduces oxidative stress and inhibits glucose absorption. DAF-16 is a transcription factor regulated downstream of the insulin signaling pathway and is one of the main factors contributing to aging and lifespan in C. elegans . Therefore, to determine the precise roles of the DAF-16 transcription factor in stress tolerance and life span, it is necessary to elucidate the signaling pathways involved in DAF-16 activation. This study was designed to elucidate the molecular mechanisms controlling the physiological stress toleran...
