Comparisons between Chinese and Mongolian Patient Satisfaction  [PDF]
Na Chen, Xinxing Zhou, Yingkui Zhang
Psychology (PSYCH) , 2017, DOI: 10.4236/psych.2017.813135
Abstract: This study compared the differences between Chinese and Mongolian patient satisfaction and investigated factors influencing patient satisfaction of the two countries in order to provide suggestions for the establishment and improvement of Mongolia’s health care system. This study involved two questionnaire surveys. Questionnaire Survey I investigated patient satisfaction of the two countries, whereas based on the first survey, Questionnaire Survey II revisited the respondents and investigated the reasons for their dissatisfaction with different aspects of health care service. According to the results of Questionnaire Survey I, Chinese overall patient satisfaction was higher than that of Mongolian. China and Mongolia had their own advantages in different health care service aspects respectively. The factors of consideration, cost of care and quality/competence showed significant influences on Chinese patient satisfaction, whereas the factors of hospitals, payment mechanisms and quality/competence showed significant influences on Mongolian patient satisfaction. According to the results of Questionnaire Survey II, Chinese individuals were more likely to express their dissatisfaction. Chinese individuals’ dissatisfaction focused on the issues of high costs of seeing a doctor, long waiting time and unreasonable procedures, whereas Mongolian individuals’ dissatisfaction focused on the issues of long waiting time, high costs of seeing a doctor and doctors’ poor attitudes. Implications were discussed for the development of Mongolia’s health care system.
Financial Development, Urbanization, and Urban-Rural Income Disparity: Evidence Based on Chinese Provincial Data  [PDF]
Zhiqiang Ye, Lixia Qian, Zhang Na
Modern Economy (ME) , 2018, DOI: 10.4236/me.2018.91003
Abstract: China’s economic development has maintained a rapid growth trend since 1978, but the problem of imbalanced income distribution between urban and rural residents also has been increasingly aggravated. This paper discusses the relationship between financial development and urban-rural income disparity and examines the impact of urbanization on the relationship between financial development and urban-rural income disparity. Then this paper selects the provincial panel data of 28 provinces in China from 1978 to 2014, using GMM dynamic model and fixed effect panel model, respectively, to do the empirical test. The results show that: 1) the imbalance of urban and rural financial resources is exacerbated by the financial threshold effect, leading to the fact that the financial development-measured by scale, efficiency and structure, respectively, expand the urban-rural income gap. 2) The developing urbanization will widen the urban-rural income gap. However, as the urbanization and mainly the urbanization of land is rapid in China, the expansion effect of the increasing financial development level on the income gap between urban and rural residents in China will be weakened with the acceleration of urbanization based on the financial threshold effect. It provides empirical support for the financial reform and for the assumption that urbanization development reduces the income gap between urban and rural areas.
Research on the Application of AHP and Fuzzy Comprehensive Evaluation of Teaching Quality in Basic Mathematics Classroom  [PDF]
Li Zhang, Hailun Fu, Na Wan
Creative Education (CE) , 2018, DOI: 10.4236/ce.2018.915197
Abstract: With the development and innovation of basic mathematics education, the classroom teaching quality has become a hot spot of basic mathematics education curriculum and teaching reform. The high classroom teaching quality can comprehensively and deeply reflect the teaching level of teachers, improve?the level of students’ mathematical key competencies, and realize?the fast improvement of mathematics learning process. Therefore,?the evaluation of it has become not only important but necessary. As a result, we argue that evaluation indicator system of teaching quality should be well researched.?Based on the multi-layered and fuzzy-paste nature of the evaluation problem of classroom teaching quality, the evaluation model of classroom teaching quality is tried to construct. By using analytic hierarchy process, the weight of each indicator is determined, and the teaching quality is determined by using the model of fuzzy comprehensive evaluation. The evaluation method improves the reliability and objectivity of the evaluation results, promoting students’ efficient learning of mathematics and teaching level.
Painting Therapy in Cancer Care: A Descriptive Systematic Review  [PDF]
Zhenting Ding, Yanqiong Ouyang, Na Zhang
Open Journal of Nursing (OJN) , 2019, DOI: 10.4236/ojn.2019.92009
Abstract: Background: Despite art therapy has been widely used in cancer population to improve their physical and mental health, painting therapy, as one form of art therapy, is seldom applied to adult cancer patients independently. Therefore, how painting therapy affects adult cancer patients’ health outcomes needed to be explored sufficiently. Objectives: The purpose of this review was to assess and synthesize the latest evidence of painting therapy concerning adult cancer patients, and to provide some inspiration for clinical staff. Methods: A literature research of PubMed, Web of Science, Cochrane Library, EMBASE, CINAHL, PsychoInfo, Psydex, CENTRAL, Google Scholar, British Library, CNKI, Wanfang, CQVIP electronic databases were undertaken with the following key words: art therapy, painting, drawing, cancer, neoplasm, tumor, carcinoma and oncology. A narrative synthesis was used according to PRISMA and the quality of study was assessed using acritical assessment tool. Results: Eleven papers reporting nine different research projects met the inclusion criteria. Generally speaking, painting therapy positively affected health outcomes. The impacts on patients include improvements in quality of life, coping with disease, mental health and somatic symptoms. However, inconsistency still exists. Three studies failed to show positive effects of painting therapy on post-traumatic growth, distress and coping behavior in participants. Conclusion: Robust evidence was found in rehabilitation of patients with various types of cancer. Painting therapy evidently affected cancer patients in a positive direction. However, the application of painting therapy to cancer patients needs to be explored further due to few studies on this topic.

Jieying He, Shengwei Zhang, Na Li
Atmospheric and Climate Sciences (ACS) , 2019, DOI: 10.4236/acs.2019.92018
Abstract: The mesoscale numerical model WRF is used to simulate the No. 8 hurricane Matthew in 2016. The radar and radiometer observations are assimilated by WRF Var. With the verification to the real situation, the process of the hurricane rainstorm is well simulated by WRF in this case that it could basically show the hurricane evolution. We use the simulation results which are model outputs with high spatial and temporal resolution to do diagnostic analysis on the short term heavy rainstorm caused by Matthew, with a comparison between the best track and forecasting tracks using active and passive microwave observations from WRFDA model. In order to analyze the inner structure, the nadiral satellite-based observations were matched between the Microwave Humidity and Temperature Sounder (MWHTS) instrument aboard the FY-3C polar-orbiting platform since Sept 30, 2013 and dual-frequency radar named PR aboard GPM satellite and then separate retrievals are demonstrated in data assimilation for extreme weather with the retrieved root-mean-square errors of about 0.9 K and 17% and 10 mm/h for precipitation products, which demonstrates the impact of 118 GHz observations in data assimilation model.

Feedback Control Variables Have No Influence on the Permanence of a Discrete -Species Schoener Competition System with Time Delays
Qianqian Su,Na Zhang
Discrete Dynamics in Nature and Society , 2010, DOI: 10.1155/2010/583203
Abstract: We consider a discrete -species Schoener competition system with time delays and feedback controls. By using difference inequality theory, a set of conditions which guarantee the permanence of system is obtained. The results indicate that feedback control variables have no influence on the persistent property of the system. Numerical simulations show the feasibility of our results. 1. Introduction The Schoener's competition system has been studied by many scholars. Topics such as existence, uniqueness, and global attractivity of positive periodic solutions of the system were extensively investigated and many excellent results have been derived [1–5]. Liu et al. [1] propose and study the global stability of the following continuous Schoener's competition model with delays: where , , and are all positive bounded and continuous functions, are positive integers, , , , . As we all know, though most dynamic behaviors of population models are based on the continuous models governed by differential equations, the discrete time models are more appropriate than the continuous ones when the size of the population is rarely small or the population has nonoverlapping generations. It has been found that the dynamics behaviors of the discrete system are rather complex and contain more rich dynamics than the continuous ones [6]. Recently, more and more scholars paid attention to study the discrete population models (see [4–13] and the references cited therein). For example, [5] considered the permanence and global attractivity of the following discrete Schoener's competition model with delays: where , , and are real positive bounded sequences, are positive integers, , , , On the other hand, as was pointed out by Huo and Li [14], ecosystem in the real world is continuously disturbed by unpredictable forces which can result in changes in the biological parameters such as survival rates. Practical interest in ecology is the question of whether or not an ecosystem can withstand those unpredictable disturbances which persist for a finite period of time. In the language of control variables, we call the disturbance functions as control variables. During the last decade, many scholars did excellent works on the feedback control ecosystems (see [14–21] and the references cited therein); however, most of those works are concerned with the continuous model and seldom did scholars considered the discrete ecosystem with feedback controls ([13, 15, 21]). Recently, Li and Yang [15] proposed the following discrete -species Schoener competition system with time delays and feedback

Binxiang Dai,Na Zhang
Discrete Dynamics in Nature and Society , 2005, DOI: 10.1155/ddns.2005.227
Abstract: A class of nonlinear delay difference equations are considered and some sufficient conditions for global attractivity of solutions of the equation are obtained. It is shown that the stability properties, both local and global, of the equilibrium of the delay equation can be derived from those of an associated nondelay equation.

Ruixian Cai,Na Zhang
Chinese Science Bulletin , 1998, DOI: 10.1007/BF02883077
Abstract: Four basic explicit analytical solutions of non-Fourier heat conduction equation simulating IC chip thermal condition are derived. Some other analytical series solutions can also be derived with the above-mentioned basic solutions. Analytical solution has its own irreplaceable important meaning in theory. In addition, as the standard solution to check the accuracy, convergence and effectiveness of various numerical computational methods and their differencing schemes, grid generation ways and so on, the analytical solution is very useful also for the newly rapidly developing computational heat transfer.
