The purpose of this study compare the difference between purchaser of counterfeit goods and non-purchaser about how self-esteem and conformity influence upon purchase intention of luxury counterfeits goods. Until existing research on purchase intention of luxury counterfeit goods have focused on the consumers' sense of superiority such as conspicuous consumption, hedonic consumption and symbolic consumption. This thesis, however, has focused on individual's psychological variables such as self-esteem and influence of reference group. The results are as follows. The purchaser of counterfeit goods tend to depend on others heavily and show a high purchase intention. On the other hand, the non-purchaser with high self-esteem are less inclined to buy counterfeit goods, and purchase intention level will also be lowed down. This thesis tries to support the assumption that personal psychological difference exist between purchaser and non-purchaser, and this result seems to correspond with the preceding studies.

The MPAA(Motion Picture Association of America) warned about serious problems of piracy due to nearly a quarter of all Internet traffic around the globe was related to Internet piracy. Thus, strong legal action is enforced for piracy over nationally through strengthen the copyright law. We in this paper conducted a survey to see whether netizens prefer to download just for the matter of their convenience. Our study becomes a motivation to consider about seriousness of piracy by comparing between Korea and foreign cases. To our surprise, the survey reveals that Korean netizens conspicuously aware of their downloading behaviors outpaces Canadian netizens. Canada lacks the basic protections for the digital environment and is a safe haven for Internet pirates.

체세포 핵이식에 의한 복제기술은 매우 낮은 성공률 나타내고 있어 실용화에 지장을 초래하고 있다. 이것은 후생적인 유전현상인 reprogramming이 불완전하게 이루어지기 때문인 것으로 추측되어지고 있다(Reik et al., Theriogenology 2003, 59: 21-32; Han et al, Theriogenology 2003, 59: 33-44). 체세포 핵이식 후에 태아사망의 원인이 태반의 비정상적인 기능과 관계가 있는 것으로 추정되는데 복제시 태아사망의 원인을 찾기 위해 본 연구를 시행하였다. 한우에서 체세포 복제 후 임신 말기에 태아가 사망한 태반조직 3개와 IVF 수정란 이식 후 동일한 시기에 제왕절개술을 실시한 태반조직 2개를 실험에 이용하였다. 태반 protein을 Two-Dimensional electrophoresis와 Mass spectrometer를 이용하여 분석 비교하였다. IPG-system을 이용하여 pH 4~7, pH 6~9에서 1차 전기영동을 한 후, 8~l6%의 SDS-PAGE gel에 2차 전기영동을 실시하였고 G-250 Coomassie로 염색하였다. gel 이미지는 Malanie III program을 이용하여 분석하였다. 전체 gel에서 약 1800개의 구분 가능한 protein spot이 나타났다. pH 4~7 범위에서 양적으로 차이나는 것 15개 중 복제한우 태반에서 증가되는 protein spot 5개와 감소하는 protein spot 10개를 골라 protein identification을 실시하였다. MALDI-TOF-MS를 이용하여 동정한 결과 phosphatidylinositol transfer protein-$\alpha$와 interleukin-18 등의 protein이 복제태반에서 발현이 증가되었고, 복제한우에서 발현이 감소되는 것으로는 vimentin, Rho-GDI-$\beta$, TRAST $\beta$-chain, ovarian sterol carrier protein 2, triosephosphate isomerase, tropemyosin beta chain, Aldose reductase 등으로 나타났다. 이러한 protein들은 inositol 지질 신호전달과 면역시스템, 세포분열, 산소 운반, steroidogenic 세포에서의 콜레스테롤 이동, 촉매 작용, 대사 작용 등에 중요한 역할을 하는 것으로 알려져 체세포 복제에 의한 태아사망 원인은 태반에서 이러한 protein들의 비정상적인 발현에 기인된 것으로 추정된다.

In this paper, we propose an efficient data replication strategy based on Peer-to-Peer which improves the performance of Data Grid system. The key idea of this replication strategy is to add the Peer-to-Peer concept for reducing data transmission restriction caused by hierarchical topology. And, it makes the nodes can store data replica to set a critical section at the storage of client level nodes. Therefore, it is possible to transmit the data replica between client level nodes and from client level nodes to upper data replication server. It is more effective to transmit data replica between client level nodes than transmitting data replica 1mm data server or data replication server with respect to minimize the transmission time. This results in improving the performance of Data Grid system. Through simulation, we show that the proposed data replication strategy based on Peer-to-Peer improves the performance of entire Data Grid environment compared to previous strategies.

When creating large crowds, it is unavoidable that the models and motions of many characters will be cloned. McDonnell implemented experiments focus on appearance and motion of characters to test user perception of crowds. As a result, appearance clones were easier to perceive than motion clones. In this paper, I researched about relation between character cloning and user perception for real-time game environment expanding McDonnell's research. This paper focuses on the way to recognition of multiple clones in dramatic environment free to change view point and has crowds move to every directions by trajectories. In particular, this paper shows the possibility of character diversification applied various shapes, colors and patterns to game item have important elements for game characters. Also, I suggests range of distances between clones by a series of experiments of user perception for clones's moving direction and distance.

The purpose of this study is to enhance the understanding of the provisions for library exceptions in copyright laws and to suggest the direction for the revision of provision in the Copyright Act of Korea. This study compares and analyzes the provisions for library exceptions in several countries' copyright law including Korea, Japan, UK, Australia and USA. This study found that the most common issues in library exception provisions are providing reproduction for users, reproduction for preservation, reproduction for interlibrary loan and digitization of library collections but the conditions for each issue are quite different. The suggestions for the revision of the library exceptions in the Copyright Act of Korea are as follows: changing the amount of reproduction of unpublished works, of works which cannot be obtained at a fair price and of periodicals for users, the transmitting digital reproduction to the user under limited conditions, preparing conditions for reproduction for preservation in libraries, preparing the applicable provisions for reproductions for interlibrary loans and for the limitation of works to be digitized and extending their use at the same time.

This study was conducted to ascertain whether the scent detection ability of a donor dog having extraordinary talent in cancer detection can be conserved through cloning. A specially trained dog for colorectal cancer detection was cloned, and she was trained and tested to detect breast cancers using breath samples collected from patients and healthy volunteers. Scent detection sensitivity of the clone was 93.3% and specificity was 99.5%, similar with those of donor (91% and 99%). Furthermore, the clone successfully detected early stage of breast cancers. Therefore, superior canine scent detection ability for cancer screening could be preserved through cloning.

The rapid development of information and communication technology has made it for people to pirate digital contents easily and quickly. Although many studies have investigated the underlying factors that lead to an individual engaging in digital piracy, few studies have provided holistic and integrative view on this issue. Therefore, this study attempts to build integrative research model based on theory of planned behavior (TPB), norm activation model (NAM), and habit. For this purpose, this study develops nine hypotheses that explain the relationship between attitude, personal norm, habit, and behavioral intention, and tests them with survey data collected from 337 participants. The results of this study show that attitude, perceived behavioral control, personal norm, and habit have impact on behavioral intention of digital piracy while subjective norm does not affect behavioral intention. This study contributes to expand existing studies by identifying the relationship between attitude, personal norm, habit and behavioral intention.

Recently, software piracy is one of the serious crimes for the digital materials. It makes economically devasting to the software industry and the market. In particular, it is a widespread phenomenon among university students in Korea and negative affects in measuring social and cultural level. Many studies have been focused on the users' intention of the software piracy for making anti-piracy policy. The purpose of this study is to investigate the factors affecting university students' software piracy intention. The survey includes responses from 271 university students in a school of business adminstration. The research model was estimated with multiple regression. The analysis showed results that user's characteristics, subjective norms, and perceived software quality were significantly related to intention of software piracy, but security policy was not. Perceived importance of intellectual property has negative impact on user's software piracy intention. Based on the findings, we suggest the implications for developing and implementing appropriate policies for anti-piracy.

We investigate the dynamic relationships among digital piracy activities, TV ratings, and online buzz for Korean TV dramas using a panel vector autoregression model. Our main findings include 1) TV ratings are negatively affected by digital piracy activities but positively affected by google buzz, 2) digital piracy activities are negatively affected by TV ratings and social buzz, and 3) social buzz and google buzz are positively influenced by each other. While many empirical studies were conducted to reveal the effects of music or movie piracy, our understanding of drama piracy is limited. We provide empirical evidence of the dynamic relationships between drama piracy, TV ratings, and online buzz. Our findings show the presence of indirect piracy effects on TV ratings through online buzz. Further, we reveal that social buzz and google trends play different roles in promoting TV ratings and piracy activities. We discuss the implications of our findings for theory and practitioners.
