The accuracy and dimensional stability of impression materials are one of the most important factors for successful prosthodontic treatment. The purpose of this study was to evaluate the accuracy of several dental elastomeric impression materials used widely and clinically : Impregum-$F^{(R)},\;Permlastic^{(R)},\;Silascon^{(R)},\;Perfect^{(R)},\;Xantopren^{(R)}$. There have been many studies to evaluate the accuracy of impression materials. But it has not been decided yet, which method was most suitable for the evaluation of the accuracy. In this study, two resin teeth, #15 & 25, were prepared with rounded shoulder margin and 90 degree cavosurface angle. For the polysulfide rubber and polyether, the custom tray was made at least 24 hours prior to impression taking. For the silicone rubber materials, putty/wash impression technique was applied in taking impressions. Marginal openings of the castings on the master dies and prepared resin teeth were measured under stereomicroscope. The results were statistically analyzed and compared between tested impression materials. The results were as follows ; 1. In the overall accuracy of impression materials, polyether was the most accurate one, followed by polysulfide, additional silicone and condensation silicone. 2. On the first model pouring, condensation silicone had the largest discrepancies and there was significant difference compared to the other impression materials. 3. Polysulfide had the least discrepancies in the first model pouring, but showed larger discrepancies in the immediate second pouring than the first pouring. 4. On the immediate second pouring, the discrepancy of polyether was shown to be the smallest, while the largest one was additional silicone. 5. Polyether and polysulfide rubber using custom impression trays showed superior accuracy to silicone rubber, putty/wash impression technique.

The owner of copyright in a work has the exclusive right to do certain specified acts in respect of that work. This means that the owner has the right to prevent others from doing those acts. The owner can either grant a licence to perform those acts or bring an action for infringement against any unauthorised performance of those acts. The acts which the copyright owner can control in this way in respect of his copyright work are copying, issuing copies to the public, performing, showing or performing the work in public, broadcasting or including the work in a cable programme. These restricted acts extend to any adaptation of the work. The adaptation will, itself, be protected as an original copyright work. Nowadays, postmodernism has a positive effect on the culture, but in general its side effect can cause serious social problems. The infringement of copyright would be discussed as one of such problems. Parody caused public discussion as a artistic expression advocating postmodernism, one of the most important tasks of copyright law is the marginal cases to regulate property such as illegal parody. However, Korean copyright law has not fully prepared for this issue. Considerring the infringement of moral rights by parody, works have a unique nature owing to the personal nature. That is to say, copyright means not only economic rights but also moral rights. Therefore, any of these two rights should not be infringed. From this reason, it is desirable to solve this problem as an infringement of moral right. Although parody is a violation of copyrights technically, it may not violate copyrights under the following conditions. First, it may be used legally for non-profit causes, not destoying the existing market of a copyrighted work. Second, a work utilizing existing materials may contain creativity and uniqueness and be recognized as a newly created copyrighted work. Third, it depends on similarity work or on the degree of parody. Fourth, the use of an original work may promote public interest. It can be conculded that the two contradictory but complementary phase of principle, which should be protected and be restricted in the copyrights and the issued protected and be restricted in the copyrights and the issued problems should be continuously dealt with and should also be considerred as social goals to promote public interest in the future.

Securing deposition is temporary and provisional disposition ordered by court. after recognizing the existence of necessities of securty and the right to be secured by securing disposition with the right which is substantial right to be secured by insurance and evidence in order to secure the right of claimant in future before fixing the decision. There are provisional attachment which effected in monetary credit, provisional disposition which effected in non-monetary credit. provisional disposition deciding temporary position to protect imminent present danger, and specific securing disposition which is common securing disposition regulated by civil procedure law. In case of provisional attachment, secured right is obligatory claim which can be converted into money or monetary claim as proprietary claim. So positional right or claim which cannot be converted into money can not be secured by provisional attachment. And there is a decision of the lower court. which that it is null and void that they have registered the provisional attachment according to the provisional attachment not applying provisional attachment but applying provisional disposition directing to refrain from doing where the secured right was monetary claim. The necessity of securing the provisial is caused by that execution of a judgement would be impossible or would be considerably difficult without it due to disturbance of present state or maintenance of its value. In case of provisial disposition regarding subject matter, claim to deliver specific Matter, calim which has a purpose of feasance, non-feasance regarding specific matter. If it is claim regarding specific matter. it can be a subject-matter whether it is proprietary claim. or obligatory claim or a claim of domestic relational law. The necessity of securing provisional disposition regarding subject-matter can be recognized in case where execution of a claim would be impossible or would be considerably difficult without it due to the change of circumstances. In case of provisional disposition deciding temporary position. as its purpose is to protect present danger. it can not be secured right in a strict sense. And in secured right of non-litigation. there are negative theory insisting that there is no room for secured right before fixing ~he decision of Judgement because the right by non-litigation can be realized concretely by the judgement, and positive theory insisting that it can not be said only the right by the procedure of non-litigation do not have resonable right on the secured -right when we see the claim in the future has reasonable right of the secure right in securing disposition. even though the secured right has not realized concretely.

본 논문에서는 먼저 선박환경에서 USN 구축을 위한 하드웨어와 소프트웨어 플랫폼을 분석하였다. 하드웨어 플랫폼에서는 기존의 CC2420기반의 mote 기술을 분석하였고 소프트웨어 플랫폼에서는 TinyOS 플랫폼을 분석하였다. 다음으로 USN 통신방식의 표준인 IEEE 802.15.4의 물리계층을 분석하고 선박USN 성능분석을 위해 Matlab을 사용하여 ZigBee/IEEE 802.15.4 물리계층에 대해 성능평가를 수행하였다. 결과적으로 이동하는 선박환경에서의 선박USN 구축에 관한 타당성을 성능평가를 통해 검증하였다. In this paper, we analyze the hardware and software platform for constructing the USN in the vessel environment. Specifically, we analyze the mote technology based on the CC2420 in the hardware platform and analyze the TinyOS platform in the software platform. We also analyze the physical layer of IEEE 802.15.4 which is the standard of the USN communication. In the simulation, we evaluate the performance in the physical layer of ZigBee/IEEE 802.15.4 by using the MATLAB and verify the validity of constructing the USN in the vessel environment based on the simulation results.
