摘要： Background: The causes of CHD are complex and often unknown, leading parents to ask how and why this has happened. Genetic counselling has been shown to benefit these parents by providing information and support;however, most parents currently do not receive this service. This study aimed to develop a brochure to determine whether an information resource could improve parents' knowledge about CHD causation and inheritance and increase psychosocial functioning. Methods: In development, the resource was assessed against several readability scales and piloted. Parents of children attending preadmission clinic for surgery were included. Assessments occurred pre- and post-receiving the information resource using a purpose-designed knowledge measure and validated psychological measures. Results: Participant's (n = 52) knowledge scores increased significantly from the pre-questionnaire ((x) over bar = 5=10, SD = 2.086) to post-questionnaire ((x) over bar = 7:88=10, SD = 2.094, p < 0.001), with all aware that CHD can be caused by genetic factors after reading the brochure. Perceived personal control also increased from pre- (<(x)over bar> = 11:856=18, SD = 4.339) to post-brochure ((x) over bar = 14:644=18, SD = 3.733, p < 0.001), and many reported reduced feelings of guilt. No negative emotional response to the brochure was reported. The information provided was considered relevant (88%), reassuring (86%), and 88% would recommend the brochure to other parents. However, some wanted more emotional support and assistance in what to tell their child. Conclusions: Use of the information resource significantly enhanced parents' knowledge of CHD causation and increased their psychosocial functioning. It is a valuable resource in the absence of genetic counselling;however, it should not replace formal genetic counselling when required.

关键词： Mobile summarizer   Container   Sematic feature   P2P search engine  

摘要： Grasping the sense of web pages on small screen of mobile devices is too difficult, so mobile users prefer summarized reports. One popular technique to generate automatic summarized report is based on vector model. The vector model summarization methods are simple and low cost to implement on mobile devices. However, the quality of summarized reports of the model may not be good because there is a semantic difference between manual summarized reports and the machine summarized reports. In addition, the censored documents of the centralized search engine cannot accurately reflect the query of user in the summary results. To overcome this constraints, automatic mobile device summarizer using a semantic feature of pseudo relevance feedback and P2P web search engine is proposed. The proposed method increases the quality of summarized reports by using the latent features of documents and clustering technique. The method uses none censored documents of the P2P web search engine to more accurately reflect user requirements in summarized reports. The automatic summarizer consists of a server-side containerized auto-summary module for flexible management of the summarization functions and a user-side mobile device module to reduce the overload of the mobile device.

关键词： Positional indexing   Text compression   Index compression   Wavelet trees   Snippet generation  

摘要： Positional ranking functions, widely used in web search engines and related search systems, improve result quality by exploiting the positions of the query terms within documents. However, it is well known that positional indexes demand large amounts of extra space, typically about three times the space of a basic nonpositional index. Textual data, on the other hand, is needed to produce text snippets. In this paper, we study time-space trade-offs for search engines with positional ranking functions and text snippet generation. We consider both index-based and non-index based alternatives for positional data. We aim to answer the question of whether positional data should be indexed, and how. We show that there is a wide range of practical time-space trade-offs. Moreover, we show that using about 1.30 times the space of positional data, we can store everything needed for efficient query processing, with a minor increase in query time. This yields considerable space savings and outperforms, both in space and time, recent alternatives from literature. We also propose several efficient compressed text representations for snippet generation, which are able to use about half of the space of current state-of-the-art alternatives with little impact in query processing time.

关键词： Keystroke dynamics   Biometrics   Search engines   Encrypted domain  

摘要： A feature of search engines is prediction and suggestion to complete or extend input query phrases, i.e. search suggestion functions (SSF). Given the immediate temporal nature of this functionality, alongside the character submitted to trigger each suggestion, adequate data is provided to derive keystroke features. The potential of such biometric features to be used in identification and tracking poses risks to user *** our initial experiment, we evaluate SSF traffic with different browsers and search engines on a Linux PC and an Android mobile phone. The keystroke network traffic is captured and decrypted using mitmproxy to verify if expected keystroke information is contained, which we call quality assurance (QA). In our second experiment, we present first results for identification of five subjects searching for up to three different phrases on both PC and phone using naive Bayesian and nearest neighbour classifiers. The third experiment investigates potential for identification and verification by an external observer based purely on the encrypted traffic, thus without QA, using the Euclidean distance. Here, ten subjects search for two phrases across several sessions on a Linux virtual machine, and statistical features are derived for classification. All three test cases show positive tendencies towards the feasibility of distinguishing users within a small group. The results yield lowest equal error rates of 5.11% for the single PC and 11.37% for the mobile device with QA and 23.61% for various PCs without QA. These first tendencies motivate further research in feature analysis of encrypted network traffic and prevention approaches to ensure protection and privacy.
