The rapid development of digital media and communication network urgently brings about the need of data certification technology to protect IPR (Intellectual property right). This paper proposed a new watermarking method for embedding contents owner's audio signal in order to protect color image IPR. Since this method evolves the existing static model and embeds audio signal of big data, it has the advantage of restoring signal transformed due to attacks. Three basic stages of watermarking include: 1) Encode analogue ID owner's audio signal using PCM and create new 3D audio watermark; 2) Interleave 3D audio watermark by linear bit expansion and 3) Transform Y signal of color image into wavelet and embed interleaved audio watermark in the low frequency band on the transform domain. The results demonstrated that the audio signal embedding in color image proposed in this paper enhanced robustness against lossy JPEG compression, standard image compression and image cropping and rotation which remove a part of image.

This paper focuses on the problem of determining the quantity and timing of disassembling used products while satisfying the demand of their parts or components over a planning horizon. The case of multiple product types with parts commonality is considered for the objective of minimizing the sum of setup, disassembly operation, and inventory holding costs. A heuristic is suggested, in which an initial solution is obtained using a linear programming relaxation method, and then improved by perturbing the given solution using a dynamic programming approach and a look-ahead check while considering the trade-offs among different cost factors.

This paper reviews the benefits of users participation in IMT-2000 standardization by the creation of users coalitions, focusing in particular on phased standards strategy necessary for the evolutionary approach from second generation to third generation systems. It first presents in detail the current status of IMT-2000 standardization progress occurring at each regional standard body including TIA of US, ETSI of Europe, TTA of Korea and ARIB of Japan. With this clear understanding of standardization situations worldwide, we may be able to come up with our standards strategies related to IPR issues and efficient standard-setting mechanism between manufacturers and service providers. In addition, this paper addresses the necessity for phased licensing of IMT-2000 service in order to avoid the high cost of new infrastructures and ensure an acceptable financial investment returns for existing cellular and PCS service providers. An author hopes that this paper can provide the adequate standardization directions of IMT-2000 to satisfy the varying regional and global market requirements.

Disassembly scheduling is the problem of determining the ordering and disassembly schedules of used products while satisfying the demand of their parts of components over a certain planning horizon. The objective is to minimize the sum of purchase, setup, disassembly operation and inventory holding costs. This paper considers products with assembly structure, i.e. products without parts commonality, and suggests a heuristic in which an initial solution is obtained in the form of the minimal latest disassembly schedule, and then improved considering trade-offs among different cost factors. To show the performance of the heuristic suggested in this paper, computational experiments were done on the modified existing examples and the results show that the heuristic can give optimal of very near optimal solutions within very short computation times.

BSA(Business Software Alliance)는 미국의 시장 조사기관인 인터내셔널 플래닝&리서치(IRP)사에 의뢰해 각국의 소프트웨어 판매자료 및 시장정보를 바탕으로 사무용 소프트웨어 불법복제 실태를 조사했다. IPR의 조사방법 등 BSA 서베이의 신뢰성에 대한 의문과 BSA 회원사 10여개 업체들이 제공한 자료의 신뢰성에 대해 의문의 여지는 남아있다. 각 업계마다 자사의 매출 발표시 조금은 부풀려지는 수치들에 대한 정확한 확인, 자사 소프트웨어의 홍보를 위해 불법복제를 방조하는 현상들에 대해 고려된 조사인가 라는 측면에서 볼 때 100% 자유로울 수 없다는 지적들이 나오고 있다. 하지만 각 연도별 우리나라를 비롯한 정부의 활동과 소프트웨어 불법복제 단속과의 상관관계는 IPR의 조사결과에 신뢰성을 더해주고 있다. 이에 세계적으로 소프트웨어 산업의 균형발전을 위해 비영리단체로 설립된 BSA의 조사결과를 게재한다.

Because of the rapid growth of Internet and multimedia applications, how to protect IPR (intellectual property rights) has become a critical issue. Is one of the ways to overcome the problem of the protection of IPR. Digital watermarking call be applied to multimedia data, such as digital images, digital video, and digital audio. In this paper, we propose a digital watermarking technique for digital images to authenticate an owner or an image by embedding visually recognizable patterns, such as logos, signatures, or stamps into images In BDCT (block discrete cosine transform) frequency domain. The proposed method sorts the components of an original image twice. At the same time, the method, also, rearranges the components of a watermark twice in order to be more robust, and finally embeds the watermark into the image. From the experimental results, the conjunction of three similarity measurements shows that our proposed method is robust to image cropping, image filtering, and JPEG (the Joint Photographic Experts Group) both subjectively and objectively.

Mean densities of two-spotted spider mite (TSM), Tetranichus urticae Koch adults from January to April in 2014 to investigate the occurrence and dispersion pattern of T. urticae on purpose of developing a monitoring method in the strawberry PVC house. Difference of density of T. urticae adult on middle and both side of leaf wasn't significantly. Density of T. urticae in investigation at different furrows and investigating points was the highest at the right and left sides of a furrow in strawberry PVC house. In results of comparing the dispersion incides of Taylor's power law (TPL) with Iwao's patchiness regression (IPR), TPL described better mean-relationship for the dispersion indieces compared to IPR. Slopes and intercepts of TPL from leaf samples did not differ among surveyed regions. Also, Distribution of T. urticae in a strawberry PVC house was the gravitation of the distribution because b and ${\beta}$ values of TPL and IPR was bigger than 1.

As advancement into global markets becomes increasingly important, there are increasing interests in high-tech companies' export. This study is an empirical investigation of the determinants of high-tech companies' export in the Daegu region seen from a resource-based perspective with focuses on organizational resources and innovative capabilities. The empirical analysis revealed that the export determinants hold truer for high-tech companies compared to companies overall, and that high-tech companies' key export determinants include organizational age as a organizational resource and international intellectual property rights (IPRs) as an innovative capability. In this sense, policies to promote high-tech companies' export should be designed to support high-tech companies that have a relatively longer history and international IPRs. The results also suggest that in the working level high-tech companies should establish their internal capabilities from a resource-based perspective, for example history and experience in their fields and international IPRs, rather than trying to target global markets from the beginning as born-global companies do.

Korea continues to invest in the IT industry and is currently regarded as one of the five major powerhouses in the field of intellectual property. However, it is evaluated that this status is only limited, and the level of intellectual property protection and dispute resolution does not reach a level commensurate with the status of one of the five major intellectual property powers. To address these problems, the Korean government has enacted the Arbitration Industry Promotion Act in 2017, which aims to strengthen national competitiveness by fostering the arbitration system as an industry and provide systematic support so that the arbitration industry can become a future growth engine. In addition, in accordance with Article 3 of the 「Arbitration Industry Promotion Act」, the Minister of Justice must establish "the Basic Plan for Arbitration Industry Promotion" every 5 years. Great efforts must be put into establishing an Online Dispute Resolution (ODR) system at the KCAB for five years from 2024 to 2028, the Second Basic Plan for the Promotion of the Arbitration Industry period. Under these circumstances, this study presents implications and improvement measures for the development of the intellectual property-related arbitration system to protect Korea's intellectual property rights and contribute to more active intellectual property creation. In particular, this study proposes a plan to build an one-stop digital platform for KCAB to implement an efficient ODR system.

A parallel importation is a non-counterfeit product imported from another country without the permission of the intellectual property owner. It is caused by price differences between countries. Therefore parallel importation are implication in issues of international trade and intellectual property rights(hereafter referred as IPR). This paper provides parallel importation issues of Korea and China under the IPR laws such as patent, trademarks, copyright and analyzes difference between two countries. In China, patent law regulates exhaustion rights which is based theory of a parallel import for the first time unlike trademark law and copyright law. On the other hands, Korea rules parallel importing under Korean customs regulations. In conclusion, two countries have no provisions that advocate a parallel import under IPR laws. This paper suggests some improvements to overcome the limitation of current regulation system and avoid trade friction between two countries. First of all, two countries should clearly make a rule about parallel import in IPR law such as definition of parallel importation, genuine goods, permission conditions, importing proses, penalty and remedy etc. Secondly, two countries should prohibit an abuse of a exclusive import agent's rights and manage a parallel importer not to cause consumer's complain about goods to expansion parallel imports. Finally, two countries should cooperate not to cause disputes about this issue with a communication channel.
