Methods: 230 cases who underwent abdominal MRI examination between 2010 January and 2012 December were collected. They were divided into three groups randomly: routine nursing group, Psychological intervention group and music therapy group. Differences in age, gender, educational level, blood pressure and heart rate were compared between the three groups; To analyze the changes of vital signs after MRI examination, MRI examination results , psychological reaction before and after MRI examination of the three groups. Results: (1)There was no significant difference in the general information (P>0.05); (2)The heart rate, respiration and blood pressure after MRI examination of patients with routine nursing increased significantly than the other two groups. And psychological nursing group was higher than the music therapy group to some extent;The MRI detection time of routine nursing group was significantly longer than the other two groups (P <0.05); (3)The one-time completion rate of the last two groups was significantly higher than the routine nursing  group (P <0.05), and music therapy group was significantly higher than that of the psychological intervention group.The adverse psychological reaction in Psychological intervention group was significantly decreased compared with routine nursing group; and music therapy group decreased significantly compared with the psychological  intervention  group (P <0.05); (4)Although the anxiety / depression score of psychological  intervention  group increased slightly ,but it significantly lower than the usual care group (P <0.05); The anxiety / depression scores of music therapy group were significantly decreased, significantly lower than the other two groups (P <0.05). Conclusion: Psychological nursing combined with music therapy is a good way to eliminate the patient's fear and anxiety, reduce their adverse reaction, help them successfully complete the MRI inspection, and we can receive satisfactory examination results.目的  探讨心理干预联合音乐疗法在腹部核磁共振扫描护理中的应用效果及意义。方法  收集2010年1月—2012年12月来聊城市人民医院行腹部MRI 扫描检查的患者共230例。将其随机分为三组: 常规护理组、心理干预组及音乐疗法组。比较三组患者在年龄、性别、文化程度、血压和心率的差异；分析三组患者MRI检查后生命体征变化、MRI检查完成情况以及MRI检查前后的心理反应测试结果有无统计学差异。结果  （1）三组患者在年龄、性别、文化程度、血压、心率等一般资料比较上无显著性差异（P>0.05）；（2） MRI检查结束后常规护理组患者的心率、呼吸以及血压与心理干预组和音乐疗法组相比明显增加。且心理干预组与音乐疗法组相比，心率、血压和呼吸均有一定程度的升高；常规护理组完成MRI检测的时间明显长于心理干预组与音乐疗法组（P<0.05）；（3）心理干预组和音乐治疗组患者MRI检查一次性完成率均显著高于常规护理组（P<0.05），且音乐治疗组的完成率明显高于心理干预组。心理干预组患者在MRI检查时不良心理反应率较常规护理组明显下降；音乐治疗组不良心理反应率较心理干预组明显下降（P<0.05）；（4）心理干预组在MRI检查后虽然焦虑/抑郁评分较MRI检查前轻度增加，但明显低于常规护理组（P<0.05）；而音乐疗法组的焦虑/抑郁评分较前明显下降，明显低于心理干预组和常规护理组（P <0.05）。结论  心理干预联合音乐疗法，可以很好的消除患者的恐惧和焦虑情绪，使患者积极配合MRI检查，减少不良反应，提高检查成功率，获得满意的检查效果

Internal corporate governance and the use of IPO over-financing: Evidence from China

AbstractIn this paper, we describe how Shenzhen A-share listed companies used funds raised in over-financed IPOs during the 2006–2010 period. In exploring the relationship between internal corporate governance and the use of funds raised in over-financed IPOs, we find that the use of such funds to engage in severe over-investment behavior is prevalent among listed companies. Reasonable internal corporate governance mechanisms can effectively alleviate over-investment problems listed companies encounter in using funds raised in over-financed IPOs. However, the same individual serving as both chairman and CEO leads to funds raised in over-financed IPOs being over-invested. Moreover, executives driven by high levels of monetary compensation are more likely to use funds raised in such IPOs to engage in over-investment. We find that improving the balance of power between shareholders will help alleviate the over-investment of excess IPO funds. In addition, the over-investment problem is less severe in state-controlled listed companies than in their non-state-controlled listed counterparts. This study provides policy recommendations for Chinese securities regulators to ensure listed companies use funds raised in over-financed IPOs both rationally and effectively

Evaluation of Arable Land Reserve Resources and Analysis of Restrictive Factors: A Case Study of Hangjin Banner in Inner Mongolia

Taking land available for cultivation and mining land available for reclamation in Hangjin Banner of Inner Mongolia Autonomous Region, using land use database of 2012 as evaluation base, it made evaluation of arability of 677 021.40 hm2 reserve land resources by the restrictive factor evaluation method. Besides, it analyzed main restrictive factors of arable land reserve resources in Hangjin Banner. Results indicate that the total area arable land reserve resources is 52 200.02 hm2, accounting for 7.71% of total area evaluated. Irrigation condition and soil thickness are major factors restricting development of arable land reserve resources in the study area. It is expected to provide reference for development of arable land reserve resources and land consolidation project in Hangjin Banner

Prediction-error of Prediction Error (PPE)-based Reversible Data Hiding

This paper presents a novel reversible data hiding (RDH) algorithm for gray-scaled images, in which the prediction-error of prediction error (PPE) of a pixel is used to carry the secret data. In the proposed method, the pixels to be embedded are firstly predicted with their neighboring pixels to obtain the corresponding prediction errors (PEs). Then, by exploiting the PEs of the neighboring pixels, the prediction of the PEs of the pixels can be determined. And, a sorting technique based on the local complexity of a pixel is used to collect the PPEs to generate an ordered PPE sequence so that, smaller PPEs will be processed first for data embedding. By reversibly shifting the PPE histogram (PPEH) with optimized parameters, the pixels corresponding to the altered PPEH bins can be finally modified to carry the secret data. Experimental results have implied that the proposed method can benefit from the prediction procedure of the PEs, sorting technique as well as parameters selection, and therefore outperform some state-of-the-art works in terms of payload-distortion performance when applied to different images.Comment: There has no technical difference to previous versions, but rather some minor word corrections.

Cavity-based architecture to preserve quantum coherence and entanglement

Quantum technology relies on the utilization of resources, like quantum coherence and entanglement, which allow quantum information and computation processing. This achievement is however jeopardized by the detrimental effects of the environment surrounding any quantum system, so that finding strategies to protect quantum resources is essential. Non-Markovian and structured environments are useful tools to this aim. Here we show how a simple environmental architecture made of two coupled lossy cavities enables a switch between Markovian and non-Markovian regimes for the dynamics of a qubit embedded in one of the cavity. Furthermore, qubit coherence can be indefinitely preserved if the cavity without qubit is perfect. We then focus on entanglement control of two independent qubits locally subject to such an engineered environment and discuss its feasibility in the framework of circuit quantum electrodynamics. With up-to-date experimental parameters, we show that our architecture allows entanglement lifetimes orders of magnitude longer than the spontaneous lifetime without local cavity couplings. This cavity-based architecture is straightforwardly extendable to many qubits for scalability.Comment: 12 pages, 9 figures, 1 table. To appear on Nature Scientific Report

Harnessing non-Markovian quantum memory by environmental coupling

Controlling the non-Markovian dynamics of open quantum systems is essential in quantum information technology since it plays a crucial role in preserving quantum memory. Albeit in many realistic scenarios the quantum system can simultaneously interact with composite environments, this condition remains little understood, particularly regarding the effect of the coupling between environmental parts. We analyze the non-Markovian behavior of a qubit interacting at the same time with two coupled single-mode cavities which in turn dissipate into memoryless or memory-keeping reservoirs. We show that increasing the control parameter, that is the two-mode coupling, allows for triggering and enhancing a non-Markovian dynamics for the qubit starting from a Markovian one in absence of coupling. Surprisingly, if the qubit dynamics is non-Markovian for zero control parameter, increasing the latter enables multiple transitions from non-Markovian to Markovian regimes. These results hold independently on the nature of the reservoirs. This work highlights that suitably engineering the coupling between parts of a compound environment can efficiently harness the quantum memory, stored in a qubit, based on non-Markovianity.Comment: 8 pages, 5 figures.
