The current web information recommendation system can not meet the personalized needs of users. To solve this problem, an open source personalized information recommendation system for web pages is proposed in the large data environment. The hardware of the system is PC-side web pages, and its development environment consists of the underlying database, software environment, development technology and user interface. Based on the hardware design of the system, the software is designed and the corresponding functions are realized, so that the software can run steadily on the platform. By collecting user data, user feature collaborative filtering, personalized correlation matching, recommendation ranking weighting and recommendation evaluation criteria, the software is designed and implemented by code. The experimental results show that the system can recommend suitable personalized information for users, and the system has advantages and reliability.

Aims: The aim of the present study was to investigate social attitudes toward schizophrenia in Japan and China in view of social distance and knowledge of psychiatry, as well as sociocultural aspects. Methods: Two self-rating scales were used to compare social distance and knowledge regarding schizophrenia in 352 Japanese subjects and 347 Chinese subjects. The Social Distance Scale–Japanese version was used to measure social distance from schizophrenia subjects in Japan. This scale consists of eight questions graded using a 4-point Likert scale (0–3 points), with higher scores representing increased social distance. A translation of the SDSJ into Chinese was used to assess social distance in China. The Knowledge of Illness and Drugs Inventory was used to determine participant knowledge of mental illness and its treatment (medication) through 20 questions (responses are graded as correct or incorrect, with higher scores indicating greater knowledge). A Chinese version of this questionnaire was also created. Results: Total scores of both scales were significantly higher in Japanese subjects than in Chinese subjects. Conclusions: Social distance associated with schizophrenia is large in both Beijing and Fukuoka, but the features of social distance differ between countries. It is important to determine the features of stigma associated with schizophrenia and develop anti-stigma programs based on trans-cultural considerations.

In a long period of the cauldron-type intermittent direct casting sheet process for producing PET films it often happens that the electric breakdown strength is too unstable to meet the technical requirements. In order to probe the factors that play a role here, the authors investigated the relations between the breakdown strength and the contents of DEG carboxyl in the PET body, and the melting point of PET. The natural characteristic of PET, the contents of DEG and carboxyl, and the melting point of PET are the main factors influencing the electric breakdown strength of the PET film. The electric breakdown strength will largely decline if the content of DEG in PET natural characteristic is high. A suitable additive can promote the enhancement of the electric breakdown strengths. >

A new method based on least square support vector machines (LS-SVM) is proposed for chaos control of fractional order system. Based on the stability theory of fractional order linear system, the system is decomposed into stable linear parts and the corresponding nonlinear parts. The active controller is designed to compensate the nonlinear parts by using the excellent nonlinearity approximation ability and better generalization capacity of LS-SVM. Thus fractional order chaotic system is suppressed to the equilibrium point. Fractional order Liu system and fractional order Chen system are illustrated respectively. The simulation results verify the effectiveness and feasibility of the proposed method.

For the projective synchronization of fractional-order chaotic systems，a controller based on active sliding mode theory is presented. Based on the stability theory of fractional-order linear system，stability of the proposed method is analysed. Two cases of projective synchronization，i.e.identical fractional-order Liu-Liu systems and different fractional-order Chen-Liu systems，are implemented separately. The simulation results show the effectiveness of the proposed controller.
