Digital copyright protection is important in the protective side of effort to have leaned to in property right and it which are intelligent of an author and is very important for development of digital contents industry. It is the misgovernment that a reproduction is easy as for the digital contents. and the original and a copy have the same characteristic, and it is so, and is experiencing what is hard for protection of copyright and large quantity illegal copy and illegal distribution prevention. CDN needs a copyright protective plan about the digital contents that digital contents providers were written jointly. The paper used a non-repudiation multi-technique for copyright protection about the digital contents which were written jointly. The Non-repudiation multi-technique proved efficiency about this.

Genetic determinant for the secondary metabolism was studied in heterologous expression in Streptomyces lividans TK-24 using Streptomyces griseus ATCC 10137 as a donor strain. Chromosomal DNA of S. griseus was ligated into the high-copy number Streptomyces shuttle plasmid, pWHM3, and introduced into S. lividans TK-24. A plasmid clone with 4.3-kb BamHI DNA of S. griseus (pMJJ201) was isolated by detecting for stimulatory effect on actinorhodin production by visual inspection. The 4.3-kb BamHI DNA was cloned into pWHM3 under the control of the strong constitutive ermEp promoter in both directions (pMJJ202); ermEp promoter-mediated transcription for coding sequence reading right to left: pMJJ203; ermEp promoter-mediated transcription for coding sequence reading left to right) and reintroduced into S. lividans TK-24. The production of actinorhodin was markedly stimulated due to introduction of pMJJ202 on regeneration agar. The introduction of pMJJ202 also stimulated production of actinorhodin and undecylproidigiosin in submerged culture employing the actinorhodin production medium. Introduction of pMJJ203 resulted in a marked decrease of production of the two pigments. Nucleotide sequence analysis of the 4.3-kb region revealed three coding sequences: two coding sequences reading left to right, ORF1 and ORF2, one coding sequence reading right to left, ORF3. Therefore, it was suggested that the ORF3 product was responsible for the stimulation of antibiotic production. The C-terminal region of ORF3 product showed a local alignment with Myb-related transcriptional factors, which implicated that the ORF3 product might be a novel DNA-binding protein related to the regulation of secondary metabolism in Streptomyces.

The watermarking method was suggested to protect the right of the copyright and the right of property, data loss is yes or not, copy prevention and pursuit about the brainchild(music, image, video and so on) in the early 1990. In this paper, we suggest the watermarking algorithm against the geometrical transformation of the medical images applied the Watershed algorithm. The robust watermarking methodology is being suggested using the several algorithm against the attacks such as compression, filtering, noise and geometrical transformation of the medical image.

To make the DRM technology protect adequately the copy right of digital contents, DRM software should have high quality and no defects when DRM is added to digital contents. It can be a basis for the effective protection of the copyright of digital contents to develop a quality evaluation model of DRM SW. First of all, the security of DRM SW is the most critical quality characteristic that DRM software must have. In this paper, we conducted research on how to measure the quality of security of DRM SW.

A cDNA clone coding for ribosomal protein 46 (rp46) which is a component of 60S ribosomal large subunit has been identified from Drosophila melanogaster. A cDNA clone encoding S. cerevisiae rp46 was used as a probe to screen a Drosophila larvae cDNA library. The DNA sequence analysis revealed that the cDNA coding for Drosophils rp46 contains a complete reading frame of 153 nucleotides coding for 51 amino acids. The deduced amino acid sequence showed 71-75% homology with those of other eukaryotic organisms. Northern blot analysis showed that about 1-kb rp46 transcripts are abundant throughout fly development. Whole mount embryonic mRNA in situ hybridization also showed no preferential distribution of the transcripts to any specific region. The chromosomal in situ hybridization revealed that the identified gene is localized at position 60C on the right arm of the second polytene chromosome with a possibility of single copy.

Curve-net interpolation surface is one of the most popular method in engineering design. Therefore it is supported with many commercial CAD/CAM system. However, construction algorithm of curve-net interpolation surfaces is rarely opened to the public because of its copy-right. In this paper we establish a construction algorithm of curve-net interpolation surface so called sweeping surface which especially concentrates on trajectory of cross-section curve. We also show the method which can construct sweeping surfaces as NURB or Bezier mathematical models. Surfaces having the form of standard mathematical models are very useful for the application of joining, trimming, blending etc. The proposed surface interpolation scheme consists of four steps; (1) preparation of guide curves and section curves, (2) remeshing guide curves and section curves, (3) blending section curves after deformation, and (4) determination of control points for sweeping surface using gordon method. The proposed method guarantee $G^1$-continuety, and construct the surface salifying given section curves and trajectory of section curves.

Nigeria Copyright Commission is saddled with the responsibility of ensuring adherence to the copyright law in Nigeria. However, it has been observed in the last decade that copyright right issue is still rampant in Nigeria. Therefore, this study analyzed cases that the Commission in involved in between years 2008 to 2018. The study adopted citation analysis. The study collected data from three selected law reports, which include Intellectual Property Law Reports, Nigerian Weekly Law Reports and Nigeria Law Intellectual Property Watch. It was found that Nigerian Law Intellectual Property Watch has the highest number of reports of cases involving Nigerian Copyright Commission while none was reported by Nigerian Weekly Law Reports. It was also found that most of the cases handled by the Commission were on copyright infringement. The study concludes that Nigerian Copyright Commission has been paying credible attention to issue that surrounds software infringement but there has been little attention paid to book piracy. Moreover, it was established that the poor attention given to book piracy may entrench the publication of pirated copy and would subsequently lead to poor library service provision at the long run.

초기 저작권(copyright)은 낱말 뜻 그대로 카피할 권리(right to copy), 즉 복사권을 의미했다. 그러나 IT의 발전과 더불어 방송권, 영화 판권 등이 이에 포함됐으며, 새로운 이용방법의 발달과 더불어 대여권이 저작권의 내용으로 논의되기에 이르렀다. 이렇듯 저작권은 사이버스페이스의 등장과 더불어 확장일로에 있으며 새로운 해석과 개념정립이 요구되고 있다. 특히 최근의 기술발전은 정보의 이동이 지리적 한계를 갖지 않으며 거래 비용의 문제도 거의 무시할 정도가 됐다. 이는 정보 중심의 사회로 가는 견인차 역할을 하고 있는 IT의 발전으로 가능해진 것이다. 그러나 IT의 발달은 소프트웨어의 불법복제 등으로 인한 창작의욕 및 산업 발전에 부정적인 영향을 주는 요인으로도 작용하고 있다. 최근 들어 정보화사회로 나아가면서 지적재산권의 개념은 정보 자체를 보호대상으로 하기 위해 본질적인 면까지 바꾸면서 정보재산권으로 발전하고 있다. 여기서는 사이버스페이스에서 논의되고 있는 저작권의 개념과 환경의 변화를 검토한다.
