The industry of digital culture contents has resulted in the high growth of added value at the area of game and movie in 2004 but the markets of animation character, and music disc have been weaken. Animation industries in Digital culture contents have attracted the attention of the people as the business of multi culture contents which has the possibility to expend and to enhance the added value nut only for the field of image and character business but also for the area of the copy right on. The stable structure of market, however, has not been settked down except a few of successful projects due to the rapid decline of 2D animation and the strong market of 3D in overseas. The purpose of this study is to analyze and research the basic logic of the market structure at the domestic business of 3D animation. In addition this paper is to suggest an alternative in terms of benchmarkin in overseas. It could be expected to achieve the effective production in this field, if the result of this study could be applied to the related world as a development model at the area of 3D animation in digital culture contents.

Even support-and-management efforts by government are enforced with the growing international restrictions for complying with global standard, not a few private enterprises are still suffering software management problems from lack of understanding the software asset management and carelessness of the software management. This is due to the ambiguous scope of software asset management as well as characteristics of software property such as invisibility, easiness of copy and installation. In other words, it is not easy for software managers to comply all the information throughout the software life cycle; from purchasing, procurement. distribution, preservation to disposition. Therefore, Inspector which has been developed for resolving these problems are proposed in this study. The inspection service consists of search algorithms adapted for software characteristics, standardization of software right management information, and practical use of registry information. Inspection time for a PC by using inspector make the inspection time much shorter. It is also shown that effective software management enables the enterprise to curtail software acquisition cost and to help rationalizing its business management.

This paper is about the part-time work and related polices in Netherland, which increased the employment rate for the past 30 years with part-time job creation. Netherland has been successful in making part-time 'good' jobs. There were many factors which contributed to increaing part-time jobs such as market, institution, policies, and industrial relations. There was virtuous cycle between increase in the supply of female labor power and increase in the demand for part-time worker in the labor market. The policies were reinforced which protect part-time workers, introduced the incentive system which was favorable to part-time wokres, guaranteed the right to select working hours to workers. Particularly, the labor market, institutions and policies were created in the midst of the social dialogue. As the polder model has been persisted for almost 30 years, the switch to full-time work or long working-hour model would not be possible. As the poler model is a very specific model based on the Netherland's own social conditions, it is not easy to copy and transplant in other countries.

When the owners of the intellectual property rights of digital content have lost control over it in the digital environment, there emerged fears that the intellectual property laws, especially copyright law, would not be effective as in the material (Offline ) world. The reason is that the digital environment helps to reproduce copies in high quality and at almost no cost, while copyright law protection has been limited to programs embedded in CDs. According to copyright laws, the owner of the program did not have the right to prevent buyers of the initial physical copy of the program from copying and reselling it to more than one individual without the permission of the original owner. As a result, business owners have invented the idea of licensing digital content and programs instead of selling them. They set out terms that serve their commercial interests regardless of their abuse to intellectual property laws or even the rules of the traditional contract to sell a material property. The abuse has resulted from the way those terms are concluded and the heavy rules that are unfair to consumer rights. Therefore, business owners insisted on dealing with the website and its programs and digital content as material property. Here raises the question of whether the website and its digital content are subject to the protection of copyright law or the rules of the traditional contract or licensing contracts. As the answer to this question affects the protection of consumer rights, is it possible to find a balance between it and the protection of the owners of digital programs' rights.That is what we will discuss in this paper.

This study aimed to propose effective ways to integrate CLO into educational settings by conducting a comparative analysis of pattern functions in YUKA and CLO, specifically focusing on skirt prototypes and variations. CLO, being a 3D virtual sample CAD tool, is mainly used in education to facilitate the creation of 3D virtual clothing. In order to explore the applicability of CLO's pattern functions in pattern education, CAD education experts were asked to produce two types of skirt prototypes and two skirt variations. Subsequently, in-depth interviews were conducted. In addition, the skirt pattern creation process was recorded on video and used for comparative analysis of YUKA and CLO pattern functions. The comparison revealed that CLO provides the pattern tools necessary for drafting skirt prototypes. The learning curve for acquiring the skills necessary for drafting and transforming skirt prototypes was found to be relatively shorter for CLO compared to YUKA. In addition, due to CLO's surface-based pattern drawing method, it is difficult to move or copy only specific parts of the outline, and there are some limitations in drawing right angle lines. In the pattern transformation process, CLO's preview function proved to be advantageous, and it was highly rated on user convenience due to the intuitive UI. Thus, CLO shows promise for pattern drafting education and is deemed to have high scalability as it is directly linked to 3D virtual clothing.

The field of medical images has been digitalized as the development of computer and the digitalization of the medical instruments. As a result it causes a lot of problems such as an illegal copy related to medical images and property right of the medical images. Therefore, digital watermarking is used for discrimination whether the data are modified or not. It is also used to protect both the property right of medical images and the private life of many patients. The proposed theories, the Non-blind and the Blind method, have two problems. One is needed an original image and the other is using a gaussian watermarking. This paper proposes the new Blind Watermarking using binary images in order to easily recognize the results of watermark. This algorism is described that an watermark of a binary image is wavelet-transformed, and then a transformed watermark is inserted in medium-band of frequency domains of original image by the Circular Input method. This method don't have any loss when image didn't have any attack. As a result Watermark can be perfectly extracted by using this algorithm. And Maximam PSNR value is improved 3.35dB. This algorithm will be improved by using gray level image and color image.

The purpose of this study is to present the functional and technical solutions for text learning of web-based textbook in which each letter has its own focal point. The solutions help learners not to lose the main focus when eye moves to the next letter or line. The text screen of the electronic textbook automatically scrolls the text to up and down or left and right directions which are preassigned by learner. It doesn't need the operation of mouse or keyboard. And learner can change scroll speed and types anytime during scrolling. Automatic text scroll function is a solution for controlling data and screen to reflect the personal favor and ability. It contains the content structure of the text(characteristics, categorizations etc.), the appearance of the text(density, size, font etc.), scroll options(scroll, speed etc.), program control type(ram resident program etc.), and the application of the screen design principles(legibility etc.). To resolve these functional problems, technical 8 phases are provided, which are environment setting, scroll option setting, copy, data analysis, scroll coding, centered focus coding, left and right focus coding, implementation. The learner can focus on text without dispersion because the text focal points stay in the fixed area of screen. 1bey read the text following their preferences for fonts, sizes, line spacing and so on.

This study examined the phenotypic and molecular characteristics of the $2^{nd}$ clone ($T_0V_2$) plants of LeLs-antisense gene-transgenic chrysanthemum line (LeLs80) that exhibited non-branching, proving the relevance of these characteristics as a factor for use in environmental risk assessment. Results of the Southern blot analysis showed that three copies of the LeLs-antisense gene were introduced into the transgenic line, and northern analysis showed that the transcripted gene was normally expressed in the transgenic line. A flanking T-DNA sequencing method was used to determine that sequences of 184 and 464 bps flanked the LeLs-antisense gene in the transgenic line. These sequences, respectively, matched the 35S promoter for expression of the npt II gene and the NOS terminator for expression of the LeLs-antisense gene within the pCAMBIA 2300 vector.

We developed 14 transgenic lines of Chinese cabbage (Brassica rapa) harboring the T-DNA border sequences and CryIAc1 transgene of the binary vector 416 using Agrobacterium tumefaciens-mediated DNA transfer. Six lines had single copy cryIAc1 gene and four of them contained no vector backbone DNA. Of the left border (LB) flanking sequences six nucleotides were deleted in transgenic lines 416-2 and 416-3, eleven nucleotides in line 416-9, and 65 nucleotides including the whole LB sequences in line 416-17, respectively. And we defined 499 bp of genomic DNA (gDNA) of transformed Chinese cabbage, and blast results showed 96% homology with Brassica oleracea sequences. PCR with specific primer for the right border (RB) franking sequence revealed 834 bp of PCR product sequence, and it was consisted of 3' end of cryIAc1, nosterminal region and 52 bp of Chinese cabbage genomic DNA near RB. RB sequences were not found and the 58 nucleotides including 21 bp of nos-terminator 3' end were deleted. Also, there were deletion of 10 bp of the known genomic sequences and insertion of 65 bp undefined genomic sequences of Chinese cabbage in the integration site. These results demonstrate that the integration of T-DNA can be accompanied by unusual deletions and insertions both in transgenic and genomic sequences.
