This application will peel off general service for investors from different IEAs, and band them together in the aspects of interface, operation and data, therefore to share and optimize the information resource.","PeriodicalId":370660,"journal":{"name":"2008 The 9th International Conference for Young Computer Scientists","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129690105","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}

As for computer teaching to non-computer majors in universities, it has become the urgent demand to serve different specialties and concentrate on application. In recent years, our university has done a lot of new exploration and reform on computer education, and accumulated some experience, one of which is attempting to introduce case teaching into programming courses. According to the characteristic of object-oriented programming subject and the features of the case-based teaching, the dissertation researches into the case-based teaching in the teaching on object-oriented programming with the action research method so as to provide experience and suggestion for the program design teaching, which promotes development of the computer teaching and enriches the teaching methods.","PeriodicalId":370660,"journal":{"name":"2008 The 9th International Conference for Young Computer Scientists","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134206334","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}

In particular, the permissions assigned to users depend on their physical positions in a reference space. When a session is established in a spatial regionby users, some spatial constraints related to thissession will be triggered and control the session process during its life automatically. There are often multiple mutually exclusive spatial roles (MESR)constraints that can enforce the same spatial separation of duty policy (SSoD). Although the different MESR constraints can enforce the same effect on the same session, we have found that the different MESR constraints are varying greatly in the enforcement efficiency. The more precise the MESR sets are defined for enforcing an SSoD policy, the less overhead the system is suffered. In this paper, we argue that enforcement of SSoD policies is realized by specifying minimal MESR constraints. By comparing the different MESR constraints which can enforce the same SSoD, we conclude the minimal MESR constraints can avoid redundant restrictiveness effectively and enforce the SSoD policy precisely. We also present an algorithm that generates all minimal MESR constraints that are precise for enforcing oneSSoD policy.","PeriodicalId":370660,"journal":{"name":"2008 The 9th International Conference for Young Computer Scientists","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132960263","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}

Firstly, a dynamic routing trust model based on trust relationship and routing behaviors is brought forward. The model not only supports trust network connection, but also gives a comprehensive assessment to the network security and efficiency affected by router access according to routers' interactive behaviors. Secondly, the trust degree between any two routers can be notified to all by a dependable flooding algorithm. Finally, a new routing strategy called by \"minimal trust routing entropy\" is proposed, which is good at avoiding nodes with low trust while taking into account the routing efficiency. This model can be used for the next-generation connection-oriented Internet which is controllable and trustworthy.","PeriodicalId":370660,"journal":{"name":"2008 The 9th International Conference for Young Computer Scientists","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131303060","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}
