Web 2.0 시대를 대표하는 핵심적인 컨텐츠는 단연 UCC이다. 사용자가 직접 만드는 컨텐츠를 의미하는 UCC는 유투브, 아프리카TV 등을 통하여 많은 수익을 거두며 관련 업계의 주목을 받고 있으나 복제와 수정, 전송이 쉬운 인터넷 환경에서 많은 저작권 문제를 내포하고 있다. 최근에는 웹을 중심으로 CCL을 통해 자신의 저작물에 대한 허용조건을 명시하여 다른 사용자에게 명시된 조건하에서 자유롭게 저작물을 이용할 수 있게 하는 방법이 널리 이용되고 있다. 그러나 CCL로 허용된 컨텐츠를 이용함에 있어서 CCL의 누락 및 위변조를 통해 저작물을 불법으로 이용하는 행위가 증가하고 있어 CCL 활성화의 장애물이 되고 있다. 또한 다양한 응용프로그램에 CCL을 적용하고 검증하기 위한 SW 플랫폼이 부재한 상태이다. 이에 본 논문에서는 효과적으로 컨텐츠에 CCL을 적용하고 CCL로 사용허가된 컨텐츠를 검증 할 수 있는 SW 플랫폼을 제안한다.

Maritime legislation encompasses a wide range of laws related to the maritime field. A significant number of laws that can be called maritime legislation have been enacted and implemented in domestic legislation. For all types of legislation, including maritime legislation, the meaning of the legal provisions must be clear for those who abide by the law, those who study the law, and those who enforce legislation. Nevertheless, the potential for considerable confusion exists because the definition is not stipulated in relation to the 'Route' specified and regulated in various maritime legislation. Further, the exact meaning of numerous cases is difficult to understand and can be interpreted in various ways. Adding to the confusion is the use of different terms with similar meanings. The maritime field changes and becomes more diverse, and many related maritime legislations are being enacted or amended to reflect this situation. The, authors propose to specify clear route definitions in individual legislation and replace parts that may cause unnecessary misunderstanding with similar terms. The authors believe that the confusion in compliance and enforcement of maritime legislation can be minimized .if these proposals are implemented.

New information technologies make it easy to access and acquire information in various ways. However, It also enable powerful and various threat to system security. To challenge these threats, various extended access control methods are being studied. We suggest a new extended access control method that make it possible to conform to security policies enforcement even with discrepancy between policy based constraints rules and query based constraints rules via their semantic relationship. New our approach derives semantic implications using tree hierarchy structure and coordinates the exceed privileges using semantic gap factor calculating the degree of the discrepancy. In addition, we illustrate prototype system architecture and make performance comparison with existing access control methods.

In this paper, I argue that it is Kripke's Tractarian notion of rule-following that prevents him from giving a non-skeptical (straight) solution to Wittgenstein's paradox. I characterize the Tractarian notion of rule-following as the 'determinate/infinistic' notion of rule-following. The later Wittgenstein, however, advocates an opposite notion of rule-following: the 'indeterminate/finistic' notion. Considering the later Wittgenstein's context-sensitive, pragmatics-oriented approach to meaning and rule-following, the later Wittgenstein could not have endorsed the determinate/infinistic notion of rule-following. To the contrary, a motive behind Wittgenstein's skeptical paradox was to blame the Tractarian notion of rule-following as the major culprit giving rise to the paradox. At the end, I argue that Kripke's adherence to the Tractarian-correspondence theory of truth also contributes to his failure to offer a non-skeptical solution to the paradox. If Kripke had noticed that the later Wittgenstein was a deflationist about truth, he could have avoided his skeptical conclusion.

Entities in reality have direct relationships between each other. They also have new and indirect relationships through such direct relationships. An ontology gives explicit meaning of such relationships. Thus, we can discover new relationships between entities based on an ontology. Such new relationships are applied in indentifying new communities or constructing social networks. Measuring for the degree of relationships is an important problem in such domains. This paper proposes a measurement for the degree of relationships between entities based on an ontology. Most of researches are based on connected paths between entities. However, there are meaningful relationships between two entities through the schema in an ontology even through there are no connected paths between the entities. The proposed method measures for the degree of relationships between two entities not based on connected paths, but also relationships through the schema. The experiment result shows that the relationships through the schema are meaningful to measure the degree of relationships between entities.

Recently, many studies on automated generation of composite Web services have been done. Most of these works compose Web services by chaining their inputs and outputs, but do not consider the functional semantics. Therefore, they may construct unsatisfied composite services against users' intention. Futhermore, they have high time-complexity since every possible combinations of available services should be considered. To resolve these problems, this paper proposes a sophisticated composition method that explicitly specifies and uses the functional semantics of Web services. Specifically, A graph model is constructed to represent the functional semantics of Web services as well as the dependency among inputs and outputs. On the graph, we search core services which provide the requested function ality and additional services which transform between I/O types of the user request and the core services. Then, composite services are built from combinations of the discovered services. The proposed method improves the semantic correctness of composite services by the functional semantics of Web services, and reduces the time complexity by combinations of functionally related services.

In ebXML, a representative framework for electronic commerce, a BPS (Business Process Specification) should be finally defined as an instance of XML-version BPSS for the configuration of B2B (Business to Business) runtime systems . In order to define the instance more complete and consistent, it is required to validate all the semantic constraints on the instance . Due to the limitations of XML Schema constructs, however, current XML-version BPSS fails to specify formal semantic constraints completely. This paper presents how to find, express and reuse BPSS semantic constraints that could not be explicitly defined in the XML-version BPSS. The method facilitates the validation of XML-version BPSS instances easily with some useful guides for fixing violations of semantic constraints. Furthermore, B2B business processes can be standardized and applied more efficiently and effectively.

The first appearance of the equations in elementary school mathematics is in the expression of the equal sign in the addition sentences without its definition. Most elementary school students have operational understanding of the equal sign in equations. Moreover, students' opportunities to have a clear concept of the properties of operations are limited because they are used implicitly in the textbooks. Based on this fact, it has been argued that it is necessary to introduce the properties of operations explicitly in terms of specific numbers and to deal with various types of equations for understanding a relational meaning of the equal sign. In this study, we use equations to represent the implicit properties of operations and the relational meaning of the equal sign in elementary school mathematics with respect to students' level of understanding. In addition, we give some explicit examples which show how to apply them to make efficient computations.
