《教战守策》的中心论点何在

《教战守策》的中心论点何在?人教社出版的高级中学语文第六册《教学参考书》说: 《教战守策》一开篇就避开一切冗词套语,单刀直入,斩钉截铁下断语:“当今生民之患”“在于知安而不知危,能逸而不能劳。此其患不见于今,而将见于他日。今不为之计,其后将有所不可救者。”这才是文章的中心论点。这个中心论点的核心是一个“患”字,中心论点的全部由三层意思组成,第一层,为患之因(知安而不知危,能逸而不能劳),第二层,为患之形(不见于今日,是隐患);第三层,防患之策(“为之计”就是献策,“策”就是“教战守”)。三层中第一层是关键,第二层。

《金匮要略》百合病病名及治疗方法分析

百合对于百合病来说既是主药又是病名,以药来命名病症的方法在历代医者那里都有不同的见地。从百合的寒热属性及药效方面对其命名进行分析,使得百合病的病因病机从另一个方面得以明确。百合病热扰心神,使得神志异常,精神不安,必须利用脉证与一般的神经官能症做区别,使之能够正确的对百合病做出诊断。在百合病的治疗方面,要充分了解已经用过的治法。在前法治疗之后,若主症未变,可依照百合病正治之法,用百合地黄汤进行治疗,若在主症之外出现变证,则要根据不同的误治法采用不同的方药治疗,不当的汗下吐法,张仲景分别给出了适用方,以期达到最佳的治疗效果。不管是对病名的研究解析还是治疗的方法分析,这些对于临床的应用研究都具有重要的探索意义。

SECURE STEGANOGRAPHY BASED ON BINARY PARTICLE SWARM OPTIMIZATION

The objective of steganography is to hide message securely in cover objects for secret communication.How to design a secure steganographic algorithm is still major challenge in this re-search field.In this letter,developing secure steganography is formulated as solving a constrained IP(Integer Programming) problem,which takes the relative entropy of cover and stego distributions as the objective function.Furthermore,a novel method is introduced based on BPSO(Binary Particle Swarm Optimization) for achieving the optimal solution of this programming problem.Experimental results show that the proposed method can achieve excellent performance on preserving neighboring co-occurrence features for JPEG steganography.

A Method for Transferring an Unknown Quantum State and Its Application

We suggest a method for transferring an unknown quantum state. In this method the sender Alice first applies a controlled-not operation on the particle in the unknown quantum state and an ancillary particle which she wants to send to the receiver Bob. Then she sends the ancillary particle to Bob. When Alice is informed by Bob that the ancillary particle is received, she performs a local measurement on her particle and sends Bob the outcome of the local measurement via a classical channel. Depending on the outcome Bob can restore the unknown quantum state, which Alice destroyed, on the ancillary particle successfully. As an application of this method we propose a quantum secure direct communication protocol. By introducing the decoy qubits the security of the scheme is guaranteed.

Cooperative Jamming for Enhancing Security of Cognitive Radio Networks with Multiple Primary Users

In cognitive radio networks(CRNs), through recruiting secondary user(SU) as friendly jammer, the secrecy rate obtained by primary user(PU) can be improved. Previous work only considered a simple scenario with a single PU in their frameworks. In this paper, we will consider a more complicated scenario with multiple PUs and try to investigate the cooperative jamming between multiple PUs and a single SU. When there are multiple PUs in CRN, in order to obtain more spectrum for data transmission, SU will cooperate with multiple PUs at the same time. Considering that both PU and SU are rational and selfish individuals, the interaction between PUs and SU is formulated as a multi-leaders and single-follower Stackelberg game, wherein PU is the leader and SU is the follower. And the Stackelberg Equilibrium(SE) is considered as the final decisions accepted by all PUs and SU. Furthermore, we also prove that when a specific condition is satisfied, the existence of SE can be guaranteed. And a Gauss-Jacobi iterative algorithm is proposed to compute a SE. Finally, simulation results are given to verify the performance and demonstrate that both of the PUs' secrecy rate and the SU's transmission rate can be improved through cooperation.

Healthcare Risk Management and Patient Safety in Turkish Hospital

Patient safety is an important component of risk management in hospitals. The aim of the study is to measure physician and nurse awareness about four selected patient safety indicators by authors and events reported about these relevant indicators in the hospital. The study uses standardized four patientsafety indicators like ＂needle sticks, cut wounds, dressing allergy, infections indicators＂. Cross section study was conducted through three month period in 2011-2012 based on voluntary response to the questionnaire that intend to measure knowledge about four health indicators. Studypopulations consisted of accessible sample of 146 different specialty physicians and 108 nurses present on duty during survey period. The association between the patient safety indicators and events reported about indicators in questionswere analyzed. Meanpatient safety knowledge questionnaire scores of health staff （nurse and physician） for needle sticks, cut wounds, dressing allergy, infections indicators were 47.13（11.8）, 39.04（14.5）, 38.02（10.5）, 39.72（9.7）, respectively. Significant statistical differences were also found between the frequency of events reported according to department and patient safety indicators （F = 8.34; p 〈 0.05） Measuring patient safety culture via safety indicators is essential in improving patient safety. This matter is perfectly influence the financial management of the hospital.

Consumers and Food Safety： Trust and Understanding of Lebanese Standards

The recent succession of food crisis and the rise of food scare have endangered the relationship of trust between the consumers and the primary food production parties： raisers, growers, industrial partners, distributors, public institutions, as well as the secondary food production parties： consumer groups and medias. Facing a potentially risky product, the consumer in his collect of risk diminishing information, should be able to trust something or someone. But in order to trust a risk diminishing element, he must first trust its emitter. In order to enhance consumer perception towards Lebanese food safety, we began a survey on a sample of a population randomly selected. The study found significant difference among education levels concerning attitude towards food safety and knowledge. No significant effect of demographic profile and sex on food handling practices was found. These findings increase concerns about consumer safety knowledge and practices. It is advised that a national survey should be conducted, followed by a properly designed food safety public health campaign, to enhance household food safety awareness.

A network security situation awareness method based on layered attack graph

The real-time of network security situation awareness(NSSA)is always affected by the state explosion problem.To solve this problem,a new NSSA method based on layered attack graph(LAG)is proposed.Firstly,network is divided into several logical subnets by community discovery algorithm.The logical subnets and connections between them constitute the logical network.Then,based on the original and logical networks,the selection of attack path is optimized according to the monotonic principle of attack behavior.The proposed method can sharply reduce the attack path scale and hence tackle the state explosion problem in NSSA.The experiments results show that the generation of attack paths by this method consumes 0.029 s while the counterparts by other methods are more than 56 s.Meanwhile,this method can give the same security strategy with other methods.

The Relationship Between Psychosocial Working Conditions and Perceived Safety Climate for Engine Room Officers in the Swedish Merchant Fleet

The purpose of this study was to analyze the relationship between psychosocial working conditions and perceived safety climate onboard the Swedish merchant fleet. Data was collected by a cross-sectional survey. The sample consisted of 640 Swedish employed engine room officers. A strong relationship was found between the psychosocial working conditions and perceived safety climate onboard （RZ = .204; P 〈 .001）. While role conflict and role ambiguity showed a negative association, social support associated positively with safety climate onboard, lob demands and control showed no relation to safety climate. The conclusion is that the safety climate onboard is strongly associated with social and relational factors.

Security-Oriented Transmission Based on Cooperative Relays in Cognitive Radio

In this paper,we propose a securityoriented transmission scheme with the help of multiple relays in Cognitive Radio(CR).To maximise the Secrecy Capacity(SC)of the source-destination link in CR,both beamforming and cooperative jamming technologies are used to improve the performance of the Secondary User(SU)and protect the Primary User(PU).The effectiveness of the proposed scheme is demonstrated using extensive simulation.Both theoretical analyses and simulation results reveal that the proposed scheme contributes to the secure transmission of the SU with acceptable attenuation of the Signal-to-Noise Ratio(SNR)at the PU receiver,and the upper bound of the SC at the SU receiver is able to exploit the power allocation strategy.

A Secure-Efficient Data Collection Algorithm Based on Self-Adaptive Sensing Model in Mobile Internet of Vehicles

Existing research on data collection using wireless mobile vehicle network emphasizes the reliable delivery of information.However,other performance requirements such as life cycle of nodes,stability and security are not set as primary design objectives.This makes data collection ability of vehicular nodes in real application environment inferior.By considering the features of nodes in wireless IoV,such as large scales of deployment,volatility and low time delay,an efficient data collection algorithm is proposed for mobile vehicle network environment.An adaptive sensing model is designed to establish vehicular data collection protocol.The protocol adopts group management in model communication.The vehicular sensing node in group can adjust network sensing chain according to sensing distance threshold with surrounding nodes.It will dynamically choose a combination of network sensing chains on basis of remaining energy and location characteristics of surrounding nodes.In addition,secure data collection between sensing nodes is undertaken as well.The simulation and experiments show that the vehicular node can realize secure and real-time data collection.Moreover,the proposed algorithm is superior in vehicular network life cycle,power consumption and reliability of data collection by comparing to other algorithms.
