In particular, the existence of malicious node aggravates this contradiction. To resolve this contradiction, social relationship theory and group theory of social psychology were adopted to do an in-depth analysis. The concrete balancing approach which leveraged Nash equilibrium theory of game theory was proposed to resolve this contradiction in reality. Thus, a new congestion control routing algorithm for security defense based on social psychology and game theory (CRSG) was put forward. Through the experiment, this algorithm proves that it can enhance the message successful delivery ratio by more than 15% and reduce the congestion ratio over 15% as well. This algorithm balances the contradiction relationship between the two key performance targets and made all nodes exhibit strong cooperation relationship in DTN.展开更多

The constitution of population dramatically turns into an elder and low-birthrate society. Therefore, the ratio of elders living along is increasing yearly. When the elders need to deal the illness and go to hospital along, decays come from degeneration might have affect on their activity in accessible environment in hospital. Signs is a vital tool for delivering and communicating information in the road sign system. Whether the elders can identify the signs in hospital clearly becomes an important issue in the current research. To understand the affect of signs design in hospital to elders, the research reviewed and gained insight of degeneration in both physical and psychological of elders and the proper principal of signs design for elders. The research surveys in Taipei City, which has densest medical center, and mainly focus on National Taiwan University College of Medicine, which has hundred years of history (founded in 1895). The research conducts field survey in both old and new buildings of National Taiwan University College of Medicine in August, 2015. The survey includes five types of signs design: Public Facilities, Prohibition, Safety, Warning, and Commercial Facilities. The result from article review indicates the most salient psychological degenerations includes the change in cognitive function, decay of memory, and deceleration of information processing; physical degenerations includes the decay of vision. As a result, the following properties should be taken into consideration when designing sings for elders: (1) The proper ratio of graphic and text. (2) Avoid using colors or matches difficult to identify by elders, like purple, blue, and green. (3) Take the visibility, legibility, identity, attention, and memory into consideration, there should be 70% differentiation in contrast between text of sign and background. (4) Avoid using multi-meaning graphic, keep the design simple. The result from the survey of National Yaiwan University College of Medicine indicates: (1) Using mainly on graphic and text as subsidiary, part of the sign design using both Chinese and English, and make sure the appropriateness of ratio between graphic and text. Use more of sans-serif font, which has better legibility. (2) Match the color mainly as yellow background with black graphic, blue background with white graphic, white background with black graphic, white background with blue graphic, a strong contrast between background and graphic on brightness and chroma matches the principle of visibility, legibility, and identity. (3) Simplify the signs design may safeguard its visibility. When elder need to handle illness comes from degeneration alone and go to large and complex hospitals frequently, the decay of their mental and physical might have a huge negative affect. Therefore, the signs design in hospital should understand their properties and design signs that match their requirement, to safeguard their live independency.展开更多

In the triple pressure with ageing population, inflation and social security transition, the value of the social security fund in our country is particularly acute. Analyses the receipts and expenditures of social security funds, investment and operation structure and put forward some rationalization proposal, which has significant meaning for a better play to the role of the social security fund and actively promote the innovation and development of China's social security fund management.展开更多

It is the inevitable choice for the development of Chinese characteristics for the aged. At present, with the continuous development of the combination of medical care and rehabilitation, the process of combination of medical care and breeding is slow, and the problems of inter departmental cooperation, high cost of resource integration and low service efficiency have emerged. The paper puts forward that multi head management of different responsibility management body is a bottleneck problem that hinders the integration of medical care. From the objective and subjective two points of view, the administrative system level barrier and the inter departmental interest game are the important reasons that obstruct the medical support and break through the estrangement of the Department and realize the cooperation. Then, according to the theory of large part system reform, the author boldly proposes the idea of establishing a new comprehensive functional department that specializes in the management of pension related affairs.展开更多

Pavement ant Tetramorium caespitum colonies must solve the problem of defending the ter- ritory that they patrol in search of energetically rich forage. When members of 2 colonies randomly interact at the territory boundary a decision to fight occurs when: 1) there is a mismatch in nest- mate recognition cues and 2) each ant has a recent history of high interaction rates with nestmate ants. Instead of fighting, some ants will decide to recruit more workers from the nest to the fighting location, and in this way a positive feedback mediates the development of colony wide wars. In ants, the monoamines serotonin (5-HT) and octopamine (OA) modulate many behaviors associated with colony organization and in particular behaviors associated with nestmate recognition and ag- gression. In this article, we develop and explore an agent-based model that conceptualizes how in- dividual changes in brain concentrations of 5-HT and OA, paired with a simple threshold-based de- cision rule, can lead to the development of colony wide warfare. Model simulations do lead to the development of warfare with 91% of ants fighting at the end of 1 h. When conducting a sensitivity analysis, we determined that uncertainty in monoamine concentration signal decay influences the behavior of the model more than uncertainty in the decision-making rule or density. We conclude that pavement ant behavior is consistent with the detection of interaction rate through a single timed interval rather than integration of multiple interactions.展开更多
