An ID-based Broadcast Encryption Scheme for Cloud-network Integration in Smart Grid
( Shufen Niu ),( Lizhi Fang ),( Mi Song Fei Yu ),( Song Han ) 한국인터넷정보학회 2021 KSII Transactions on Internet and Information Syst Vol.15 No.9
The rapid growth of data has successfully promoted the development of modern information and communication technologies, which are used to process data generated by public urban departments and citizens in modern cities. In specific application areas where the ciphertext of messages generated by different users’ needs to be transmitted, the concept of broadcast encryption is important. It can not only improve the transmission efficiency but also reduce the cost. However, the existing schemes cannot entirely ensure the privacy of receivers and dynamically adjust the user authorization. To mitigate these deficiencies, we propose an efficient, secure identity-based broadcast encryption scheme that achieves direct revocation and receiver anonymity, along with the analysis of smart grid solutions. Moreover, we constructed a security model to ensure wireless data transmission under cloud computing and internet of things integrated devices. The achieved results reveal that the proposed scheme is semantically secure in the random oracle model. The performance of the proposed scheme is evaluated through theoretical analysis and numerical experiments.
An Improved Model of General Data Publish/Subscribe Based on Data Distribution Service
Shufen Liu,Xuejun Ma,Xinyong Wang 보안공학연구지원센터 2016 International Journal of Database Theory and Appli Vol.9 No.11
Most existing data publish/subscribe systems applied in a particular field, the lack of generality. In order to satisfy the general support for interdisciplinary model, proposed an improved model of general data publish/subscribe. The model supports the configuration and modification of the underlying data types. In order to avoid the impact on the application layer while changing the underlying DDS product, proposed an encapsulation on DDS based on the abstract factory pattern. Finally, through simulation experiments to verify the feasibility of the proposed model, the simulation results show that the improved model can be well applied to various types of data publish/subscribe occasions, with high performance.

Liu Ruyi,Wang Shufen 국제온돌학회 2013 International Journal of Ondol Vol.6 No.1
The core of vertical space greening of urban architecture which is an effective approach to build the green healthy living environment and to increase urban green space, is the ecological planting epidermis design. By means of learning the experience of international ecological planting design of construction epidermis, the paper reviews principles of ecological planting design of construction epidermis and the relationship between this and planting design, which bases on the concept of BBL, the bioclimatic buffering layer. Furthermore, it aims to find new creative ideas of the combination of green plants and construction epidermis design, in order to provide references for Chinese construction epidermis design practice.

Previous studies demonstrated that depression is more prevalent in women with polycystic ovary syndrome (PCOS). In this study, we aimed to determine whether amitriptyline (AMT), an antidepressant drug, plays a role in preventing PCOS. The results showed that AMT modified ovarian morphology improved the ovarian functions and estrus cycle in estradiol valerate (EV)-induced polycystic ovary (PCO). AMT restored the levels of estradiol (E2), testosterone (T) and progesterone (P4) to normal, and elevated the level of luteinizing hormone (LH) in EV-induced PCO. No significant changes in follicle stimulating hormone (FSH) levels were observed in rats with EV or AMT treatment. The restoration of norepinephrine (NE) level was detected in rats with EV-induced PCO. AMT also altered the expression levels of steroidogenesis genes and beta2-adrenoceptor (beta2-AR) in EV-induced PCO. Our data revealed that AMT improves the ovarian morphology and modifies ovarian expression of beta2-AR and steroidogenesis genes in rats with EV-induced rat PCO. Our data provide support for the hypothesis that AMT is considered as a candidate drug for preventing and treating PCOS along with depression.
An Effective Feature Selection Approach Using the Hybrid Filter Wrapper
Haitao Wang,Shufen Liu 보안공학연구지원센터 2016 International Journal of Hybrid Information Techno Vol.9 No.1
Feature selection is an important data preprocessing technique and has been widely studied in data mining, machine learning and granular computing. In this paper, we introduced an effective feature selection method using the hybrid approaches, that is, use the mutual information to select the candidate feature set, then, obtain the super-reduct space from the candidate feature set by a wrapper search approach, finally, the wrapper method determined to select the proper features. The experimental results show that our approach owned the obvious merits in the aspect of classification accuracy ratio and number features selected by extensive comparing with other methods.
An Approach of Information Extraction Based on Dom Tree and Weight Value
Haitao Wang,Shufen Liu 보안공학연구지원센터 2016 International Journal of Grid and Distributed Comp Vol.9 No.10
Eliminating noisy information and extracting information content from web pages are increasing to become an important research issue in information retrieval field. In this paper, we present an approach of information extraction based on Dom tree and weight value calculation, which contains the following steps, parse the web page to construct the Dom tree, extract the title and keywords, calculate the weight value and obtain the content. The experimental result shows that this method has the higher accuracy ratio by the various themes content extraction.

Background/Aims This study was to investigate whether transforming growth factor-β1 (TGF-β1) plays a role in hyperalgesia in chronic pancreatitis (CP) and the underlying mechanisms. Methods CP was induced in male adult rats by intraductal injection of trinitrobenzene sulfonic acid (TNBS). Abdominal hyperalgesia was assessed by referred somatic behaviors to mechanical stimulation of rat abdomen. Dil dye injected into the pancreas was used to label pancreas-specific dorsal root ganglion (DRG) neurons. Whole cell patch clamp recordings and calcium imaging were performed to examine the effect of TGF-β1 on acutely isolated pancreas-specific DRG neurons. Western blot analysis was carried out to measure the expression of TGF-β1 and its receptors. Results TNBS injection significantly upregulated expression of TGF-β1 in the pancreas and DRGs, and TGF-β1 receptors in DRGs (T9-T13) in CP rats. Intrathecal injection of TGF-β receptor I antagonist SB431542 attenuated abdominal hyperalgesia in CP rats. TGF-β1 application depolarized the membrane potential and caused firing activity of DRG neurons. TGF-β1 application also reduced rheobase, hyperpolarized action potential threshold, and increased numbers of action potentials evoked by current injection of pancreas-specific DRG neurons. TGF-β1 application also increased the concentration of intracellular calcium of DRG neurons, which was inhibited by SB431542. Furthermore, intrathecal injection of TGF-β1 produced abdominal hyperalgesia in healthy rats. Conclusions These results suggest that TGF-β1 enhances neuronal excitability and increases the concentration of intracellular calcium. TGF-β1 and its receptors are involved in abdominal hyperalgesia in CP. This and future study might identify a potentially novel target for the treatment of abdominal pain in CP.
