An Improved SPIHT Algorithm for Image Compression in Low Bit Rate  [PDF]
Ping Liu, Guanfeng Li
Communications and Network (CN) , 2013, DOI: 10.4236/cn.2013.53B2045
Abstract: Aiming at shortage of the SPIHT algorithm, an improved image compression algorithm is proposed, in order to overcome the shortcomings of decoding image quality and coding time, LS9/7 lifting wavelet transform is adopted. According to the characteristics of the human visual system (HVS), the scanning mode and the method to determine the threshold of algorithm are changed to improve the quality of reconstruction image. On the question of repeating scan of SPIHT algorithm, using maximum list thought, greatly reduce the computation and save operating time. The experimental results have proved that the improved algorithm of image decoding time and the quality of reconstruction images are better than the original algorithm , especially in the case of low bit rate.

A Critique of “Moral and Character Development”
Ping LIU
Management Science and Engineering , 2009,
Abstract: A critique was made in this essay about William G. Huitt’s (2004)article titled “Moral and Character Development”. The strong points of his article were discussed with his conclusion that social and cultural values influence the formation of children’s character traits, while school should play its own role as a sub-social unit to develop their characters and morality based on the cognitive, affective, conative and behavioral principles. The obvious weakness was presented by ignoring politics to be a vital factor influencing moral development. This essay aims to discuss why moral principles can be taught in school and how moral education can be practiced in classroom. It proposes what approaches are supposed to be significantly effective. Keywords: Moral education; Character development; Behavioral principles; Cognition; Psychological approaches

Abstract: Objective: To study the modulation of Jianjining Recipe (JJNR), a traditional Chinese compound herbal medicine for invigorating spleen and kidney on differential protein expression in spleen of rats with experimental autoimmune myasthenia gravis (EAMG).Methods: EAMG rats were randomly divided into four groups: untreated group, JJNR-treated group, Qiangji Jianli capsule (QJJLC, a traditional Chinese compound herbal medicine)-treated group and prednisolone acetate (PA)-treated group. After therapeutic intervention with the above drugs for four consecutive weeks, the level of differential protein expression was analyzed by two-dimensional electrophoresis and matrix assisted laser desorption/ionization time-of-flight mass spectrometry.Results: Twelve differential proteins were identified by comparing EAMG rsts and normal rats. The levels of allograft inflammatory factor-1, peroxiredoxin Ⅰ and actin-related protein 2/3 complex subunit 5 were significantly regulated by JJNR (P<0.01). These proteins were closely associated with immune response and cell movement.Conclusion: The results suggest that there are differential protein expressions between EAMG rats and normal rats. Furthermore, as a Chinese medicine prescription with effect of invigorating spleen and kidney, JJNR can effectively regulate the levels of some EAMG-related protein expression.

Zhong Xi Yi Jie He Xue Bao , 2003,
Abstract: ABSTRACT: The treatment for severe acute respiratory syndrome (SARS) that happened epidemically this spring confirmed again that the integrated traditional Chinese and western medicine had its clinical advantage and vitality, and indicated that this integration could benefit the pathologic understanding and therapeutic strategies for the diseases. Based on the experimental research, western medicine focuses on the histological and structural changes of the diseases. In order to probe the key mechanisms of the disease's occurrence and development, it trys to develop the therapy targeting the mechanism.Materialism is the academic characteristic of western medicine. Based on the differentiation of individual patient and comprehensive analysis of all manifestations, with the academic characteristic of dynamics and dialectics, traditional Chinese medicine (TCM) focuses on the regulation and recovery of the body functions. Theoretically, materialism and dialectics are complementary to each other. Their combination and unity is the key point for the integration of TCM with western medicine in order to improve the clinical effectiveness and TCM development. Therefore, we must adhere to the principles of the evidence-based medicine, strengthen the integrated study on "disease" of western medicine and "syndrome" of TCM, insist on "materialism" and improve the understanding of the mechanism of Chinese herb formula, pay efforts on the clinical study of difficult and common hepatic diseases, in order to develop the integrated traditional and western medicine on liver diseases.

Zhong Xi Yi Jie He Xue Bao , 2004,
Abstract: The strategy for treating liver fibrosis in chronic hepatitis patients includes dispelling the etiological factors, inhibiting the inflammatory reaction, decreasing the sedimentation of extracellular matrix, accelerating the degradation of extracellular matrix, improving the microcirculatory and metabolic disturbance, and ameliorating the complicating diseases, etc. Researchers should pay attention to the liver function indexes in chronic liver disease in evaluating the therapeutic effects of anti-fibrosis. Effective etiological treatment should be considered as the first step in treating liver fibrosis in chronic hepatitis patients, and inhibiting the inflammatory reaction is one of the most important tactics for suppressing the development of fibrosis and for decreasing the incidence rate of liver cancer in chronic hepatitis patients. Treatment based on syndrome differentiation, a dynamic therapy aimed at the holistic pathological state, can improve the pathological state of the disease. It is especially important to take the advantages of the integration of traditional Chinese and western medicine in the clinical diagnostic and therapeutic procedure for increasing the therapeutic effect of live fibrosis.

Abstract: Objective: To study the efficacy and safety of Fuzheng Huayu Capsule (FZHY Capsule) against liver fibrosis with chronic hepatitis B. Methods: Multicentric, randomized, double blinded and paralleled control led trial was conducted on patients (aged between 18 and 65) with liver fibrosis in chronic hepatitis B.Indexes observed: (1) hepatic histological changes and HBV markers were observed at 0 and 24th week during the treatment; serological indexes (HA, LN, P-Ⅲ-P, Ⅳ-C) were determined and B ultrasound examination of spleen and liver was taken at 0, 12th, 24th week; liver function (during the period of follow-up, liver function and serological indexes for liver fibrosis were evaluated) were observed at 0, 6th, 12th, 18th, 24th week; (2) indexes for safety: blood and urine routine tests, renal function and ECG were examined. Results: (1) Enrollment and demographic data: There was no significant difference between the trial (110 cases) and control group (106 cases) in demographic feature, vital signs, course of illness,history for drug anaphylaxis, history of previous therapy, liver function, serological indexes for liver fibrosis, liver histological examination (99 cases for test group, 96 cases for control group), HBV markers, and renal function, etc. (2) Histological pathological examination: 93 cases of liver histological examination were taken, of these 50 cases for the trial group and 43 cases for control group which turned out to be at S mean value of 2.33 and 2.11 respectively pretreatment according to criteria for liver fibrosis staging. Post-treatment, the trial showed a significant decrease with S value of 1.80 compared to that of pretreatment; however, there was no significant improvement in control group before and after the treatment with S mean value of 2.14. There was significant difference in reversing rate (decrease at least 1 stage according to criteria for liver fibrosis staging) between the trial (52%) and control (23.3%) after liver biopsy. The trial had a rather good effect on improving inflammatory activity and was superior to control group with a marked decrease of mean value of inflammatory activity and score of inflammation (P<0.05). (3) Serological indexes for liver fibrosis: There was a significant decrease in HA, LN, P-Ⅲ-P, Ⅳ-C content in test group after 12 and 24 weeks' treatment compared to that of pretreatment; the differences of HA, LN, P-Ⅲ-P, Ⅳ-C between 12 , 24 weeks' treatment and pretreatment were significantly greater than control group (P<0.01 or 0.05); the effectual was defined as 2 of 4 indexes lowered more than 30%

Canadian Social Science , 2009,
Abstract: For ESL teaching in China’s universities, not enough emphasis is put on verbal communication as a yardstick of language mastery and methodological success. Developing student’s communication competence is not only concerned with the nature of language learning from linguistic perspectives, but also could be influenced by such exogenous factors as learning environment, learning psychology, and learning strategies. It is necessary to investigate whether these factors have an impact on Chinese university students’ English communication performance. This paper tries to examine the relationships among social needs, system inefficiencies, learning objectives, learning strategies, and effort, according to a constructed model. The model’s hypotheses are drawn from theories as diverse as person-environment (PE) fit (Caplan, 1987), intrinsic motivation (Ryan and Deci, 2000), conceptions about learning approach (Entwistle, 1990), and “learning strategy” (Biggs, Kember, & Leung, 2001). The sample was collected from one of the Chinese universities in Southeast for a case study to shed light on how to improve English teaching and learning in TESL of China. The quantitative research method is used with SPSS system in this essay to report the statistical analyses of the model. Among the eight hypotheses tested, six were confirmed to be true, and two could not be validated. Key words: communication performance; 5-factor model; person-environment (PE) fit; intrinsic motivation; learning strategies Résumé: Dans les universités chinoises où l’anglais est enseigné comme la deuxième langue, l'accent n'est pas suffisamment mis sur la communication verbale en tant qu’un critère de ma trise de la langue et du succès méthodologique. Le développement de la compétence communicative des élèves n'est pas seulement concerné par la nature de l'apprentissage des langues du point de vue linguistique, mais pourrait aussi être influencé par des facteurs exogènes comme l'environnement d'apprentissage, la psychologie de l'apprentissage et les stratégies d'apprentissage. Il est nécessaire d'examiner si ces facteurs ont une influence sur la performance de communication en anglais des étudiants chinois. Le présent document tente d'étudier les relations entre les besoins sociaux, l'inefficacité du système, les objectifs d'apprentissage, les stratégies d'apprentissage et des efforts, selon un modèle construit. L’hypothèse du modèle vient de diverses théories, telles que la théorie de l’adaptation peronne-environnement-(PE) (Caplan, 1987), la motivation intrinsèque (Ryan et Deci, 2000), les concep
