In this paper, a quantification method for NSSA based on conditional random fields(CRFs) was proposed. The data of network attacks from Intrusion Detection System (IDS), the hosts’ vulnerabilities and the hosts’ states were firstly combined as the network security factors. And then the network security threat degree was defined to quantify the risk of the whole network and classify the attacks. A diverse set of effective features were incorporated in CRFs Model. Finally the experiments on the DARPA 2000 data set generate the explicit network security situational graph. It proves that the method introduced in this paper can represent network risk more accurate and offer a good quantification for the network security situation.","PeriodicalId":112416,"journal":{"name":"2009 Fourth International Conference on Computer Sciences and Convergence Information Technology","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116662913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meurant","doi":"10.1109/ICCIT.2009.192","DOIUrl":"https://doi.org/10.1109/ICCIT.2009.192","url":null,"abstract":"Although digital resources play an increasing role in Second Language Acquisition (SLA), Korean learners of English are provided with little deliberate instruction in Second Language (L2) Digital Literacy. Student computer usage for SLA purposes is minimal, but is governed by teacher expectations; if teachers do not encourage student use of computers in English, this will not likely spontaneously occur. Institutional recognition of the importance of L2 digital literacy to SLA is also limited. However, the predominant use of English by non-native speakers will be in communication with other non-native speakers, not with native speakers. Secondly, the emergence of English as a global language has meant that the predominance of online discourse is in English. Thirdly, a critical threshold is approaching where the majority of interpersonal communications will be computer-mediated, rather than face-to-face; and this trend will likely accelerate. Non-native speakers will mainly use their English to navigate English language digital resources, and publish online content in English; and in computer-mediated communication with other mainly non-native speakers of English. Therefore L2 Digital Literacy in English is critically important to student development. Proactive use of English-language digital resources is needed, as is the teaching and learning of English-language digital skills.","PeriodicalId":112416,"journal":{"name":"2009 Fourth International Conference on Computer Sciences and Convergence Information Technology","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125272714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The second stage is for students to design each module in detail, considering relationships between modules. In this stage, students design procedures with roles of arguments. Since there are two stages for designing the behavior, teachers can force students to design it logically.

In this paper, we aim to reuse existing mesh models to reproduce a virtual character by means of the proposed mesh fusion method. In comparison with the conventional fusion methods, we tend to develop a rapid method instead of devising an off-line technology. The proposed method first selects two fragmented models that have been cut in advance by users, and integrates the mesh fragments into a complete model with little user interference. In order to associate the two mesh fragments with each other, a unit circle is used to project two open cutting boundaries on it; in addition, we take advantage of mesh morphing to generate a mesh patch in between the two open cutting boundaries and smooth the patch by using the Bezier interpolation. The experimental results show that the proposed method will be able to create a virtual character with an even in-between patch and a low time complexity.","PeriodicalId":112416,"journal":{"name":"2009 Fourth International Conference on Computer Sciences and Convergence Information Technology","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128099184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This diffusion is considered an outcome of economic, political, geographical and cultural factors. Literature review shows that role of cultural factor in mobile phone service diffusion is still understudied. The rate of adoption and diffusion differs considerably across the countries. This study attempts to analyze the impact of national culture on the adoption and diffusion of mobile phone services. For this purpose, the study adopts the mobile penetration data of and uses Hofstede’s cultural dimension values across different countries. Based on the Hofstede’s cultural dimension values, the countries are categorized into different clusters. Then the coefficient of innovation effect and imitation effect is determined by using Bass diffusion model. Finally a comparison is made among the clusters to infer whether the culturally similar countries have similar adoption and diffusion behavior than culturally dissimilar countries.","PeriodicalId":112416,"journal":{"name":"2009 Fourth International Conference on Computer Sciences and Convergence Information Technology","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133627915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
