Research on the Present Situation, Dilemma and Countermeasures of the Institutional Old-Age Care Model of “CMHC”*
—Taking Xinyu Yinhe Park Elderly Service Center as an Example
 [PDF]

Open Journal of Social Sciences (JSS) , 2017, DOI: 10.4236/jss.2017.54007
Abstract: Based on the practical background of aging of the Chinese population and the “Separation of Medical and Health Care” and faced with the demand for health care services increasingly, this paper attempts to analyze the current development situation of the old-age care model of “CMHC” institutions, thus puts forward feasible suggestions for perfecting the old-age care model of “CMHC” institutions in China. This paper takes Xinyu Yinhe Park Elderly Service Center, Jiangxi Province as an example, adopts the method of questionnaire survey and interview, investigates the operation status of the center, the basic situation of nursing staffs, the basic situation of the elderly and their satisfaction of life, and analyzes the survey results by using the method of descriptive statistical. The study finds that the old-age care model of “CMHC” institutions in China is in the stage of exploration and development, which is faced with the lack of talents, low service level, the shackles of traditional old-age concept, the lack of government policy support, shortage of funds, the disordered management of government departments and other internal and external difficulties in “CMHC” institutions. Based on the previous study, this paper argues that we shall improve and develop the old-age care model of “CMHC” institutions in our country, and must support this patter with a long-term policy, attach importance to “CMHC”, encourage the active participation of social forces, and vigorously cultivate talents in “CMHC” under the guidance of the government, and then establish long-term care insurance system, so as to create a good internal and external environment for the development of “CMHC” old-age care service in China, and thus contribute to the development of China’s old-age care business.
Adsorption Application for Removal of Hazardous Chloroform from Aqueous Solution by Nanocomposites Rectorite/Chitosan Adsorbent  [PDF]
Shiqian Li, Peijiang Zhou, Ling Ding
Journal of Water Resource and Protection (JWARP) , 2011, DOI: 10.4236/jwarp.2011.36055
Abstract: A novel nanocomposite bioadsorbent rectorite/chitosan was prepared by controlling different mass ratios of chitosan to rectorite using the water phase intercalation technique. The structure of the bioadsorbent was characterized by Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD) and scanning electron microscopy (SEM), Transmission electron microscopy (TEM), respectively. The results showed that the chitosan had been inserted into the rectorite layer successfully. The adsorption properties of the nanocomposite adsorbent toward CHCl3 from aqueous solution were investigated. Adsorption results showed that both nanocomposite adsorbents with weight ratio of rectorite to chitosan of 3:1 and 5:1 exhibited higher adsorption capacities.

Abstract and Applied Analysis , 2012, DOI: 10.1155/2012/862989
Abstract: A modified function projective synchronization (MFPS) scheme for different dimension fractional-order chaotic systems is presented via fractional order derivative. The synchronization scheme, based on stability theory of nonlinear fractional-order systems, is theoretically rigorous. The numerical simulations demonstrate the validity and feasibility of the proposed method.
An Adaptive Tracking Control of Fractional-Order Chaotic Systems with Uncertain System Parameter
Ping Zhou,Rui Ding
Mathematical Problems in Engineering , 2011, DOI: 10.1155/2011/521549
Abstract: An adaptive tracking control scheme is presented for fractional-order chaotic systems with uncertain parameter. It is theoretically proved that this approach can make the uncertain parameter fractional-order chaotic system track any given reference signal and the uncertain system parameter is estimated through the adaptive tracking control process. Furthermore, the reference signal may belong to other integer-orders chaotic system or belong to different fractional-order chaotic system with different fractional orders. Two examples are presented to demonstrate the effectiveness of the proposed method. 1. Introduction In nonlinear science, chaos synchronization is a hot topic, which has attracted much attention from scientists and engineers. In the past decades [1–13], various methodologies in control of chaotic system have been proposed, such as variable structure control approach, adaptive control approach, and time-delay feedback control. Up to date, the interest of the scientific community and engineering technological applications in controlling chaotic dynamics has increased after the development of the approach of “tracking,” which can be used to follow an unstable fixed point or an unstable periodic orbit embedded or an arbitrary given reference signal in different dynamical regimes [3, 8–11]. In electronic and laser systems, the experiments on tracking the unstable periodic orbits and steady states were carried out [12, 13]. Some researchers design a controller based on the reference signal and make the output of the chaotic system follow the given reference signal successfully [10, 11]. However, many existed tracking control methods mainly focus on chaotic systems of integer orders [11, 14–17]. Up to now, there have been only a few papers on tracking control for fractional-order chaotic systems [18, 19]. In [18], tracking control of the fractional-order hyper-chaotic Lü system was reported, in which all the system parameters were exactly known. In [19], an adaptive tracking control of the fractional-order hyper-chaotic Lorenz system with unknown parameters was also reported. But, the tracking control methods in [18, 19] were unusual and only suited for specific fractional-order chaotic system, and the given reference signals do not belong to different fractional-order chaotic systems. Inspired by the above discussion, in this paper, a more universal adaptive tracking control method for fractional-order chaotic system with uncertain system parameter, which is different from the previous works, is given based on the stability theory of
Control and Synchronization of the Fractional-Order Lorenz Chaotic System via Fractional-Order Derivative
Ping Zhou,Rui Ding
Mathematical Problems in Engineering , 2012, DOI: 10.1155/2012/214169
Abstract: The unstable equilibrium points of the fractional-order Lorenz chaotic system can be controlled via fractional-order derivative, and chaos synchronization for the fractional-order Lorenz chaotic system can be achieved via fractional-order derivative. The control and synchronization technique, based on stability theory of fractional-order systems, is simple and theoretically rigorous. The numerical simulations demonstrate the validity and feasibility of the proposed method.

A Class of Three-Weight Cyclic Codes
Zhengchun Zhou,Cunsheng Ding
Mathematics , 2013,
Abstract: Cyclic codes are a subclass of linear codes and have applications in consumer electronics, data storage systems, and communication systems as they have efficient encoding and decoding algorithms. In this paper, a class of three-weight cyclic codes over $\gf(p)$ whose duals have two zeros is presented, where $p$ is an odd prime. The weight distribution of this class of cyclic codes is settled. Some of the cyclic codes are optimal. The duals of a subclass of the cyclic codes are also studied and proved to be optimal.
Binary Cyclic Codes from Explicit Polynomials over $\gf(2^m)$
Cunsheng Ding,Zhengchun Zhou
Computer Science , 2013,
Abstract: Cyclic codes are a subclass of linear codes and have applications in consumer electronics, data storage systems, and communication systems as they have efficient encoding and decoding algorithms. In this paper, monomials and trinomials over finite fields with even characteristic are employed to construct a number of families of binary cyclic codes. Lower bounds on the minimum weight of some families of the cyclic codes are developed. The minimum weights of other families of the codes constructed in this paper are determined. The dimensions of the codes are flexible. Some of the codes presented in this paper are optimal or almost optimal in the sense that they meet some bounds on linear codes. Open problems regarding binary cyclic codes from monomials and trinomials are also presented.

Guozhong Ding, Feng Wu, Gang Zhou, Xiaoqing Zhang, Jiuyang Yu
Engineering (ENG) , 2009, DOI: 10.4236/eng.2009.11003
Abstract: An active thermo-acoustic network model of regenerator which is a key component to accomplish the con-version between thermal-and acoustic power in thermo-acoustic system has been established in this paper. The experiment was carried out to quantify the network. A method called least square is employed in order to identify the H matrix describing the system. The results obtained here show that the active thermo-acoustic network can reliably depict the characteristics of a thermo-acoustic system.
