  • 골아세포의 생물학적 기능을 증진시키기 위해 키토산의 표면개질에 대하여 연구하였다. 생체적합성 천연고분자인 키토산은 1차 아미노기를 소유하고 있으므로 적정한 공유결합제를 사용하여 세포성장인자와 같은 생리활성을 지닌 단백질을 키토산의 표면에 고정시킬 수 있다. 본 연구에서는 키토산을 필름형태로 제조하여 세포성장인자 중 형질전환성장인자를 고정하고 골아세포의 부착, 성장 및 분화를 증가시키고자 하였다. 형태전환성장인자의 고정화 효율은 단순한 흡착방법에 비해 높았으며, 표면에 형성된 공유결합은 매우 안정하였다. 골아세포를 배양하여 초기세포부착능에 대한 영향을 연구한 결과, 배양 후 4시간, 1일째, 형질전환성장인자를 고정한 키토산 표면에서 고정하지 않은 키토산의 표면에 비해 더 많은 수의 골아세포가 부착되었고, 더 많이 신장된 부착형태를 보였다. 세포활성정도와 배양 후 4주일째의 칼슘축적량을 측정한 결과, 형질전환성장인자를 고정한 키토산 표면에서 고정하지 않은 키토산의 표면에 비해 더 높았다. 위의 결과는 키토산 표면에 형태전환성장인자의 고정이 성공적으로 이루어졌으며, 또한 실제로 활성이 있는 것이 증명되었다. 위의 연구 결과에서 형질전환성장인자로 고정된 키토산은 골아세포의 초기 부착 및 분화를 촉진시켰음을 알 수 있었던 바 성장인자의 표면고정은 임플란트 및 조직공학용 지지체에도 적용하여 생체적합성과 세포기능을 증진시키는데 이용할 수 있음을 알 수 있었다.

  • 이 연구의 목적은 우리의 근대 도서관사에 있어 자료조직에 대한 지적 토대가 어떻게 형성$\cdot$발전되어 왔으며, 이 과정에서 우리는 그동안 우리 고유의 지식문화와 정보행태를 대변하는 '토착적' 가치를 지닌 자료조직이론을 정립하기 위해 얼마나 노력해 왔는지를 역사적 관점에서 엄격하게 성찰해 보는데 있다. 이를 위해, 지난 반세기동안 도서관계 혹은 문헌정보학계에서 생산된 자료조직 연구물들을 수집하여 이들이 어떠한 토대와 근거를 바탕으로 생산되었으며. 어떠한 내용으로 이루어졌는지를 정성적 관점에서 살펴보았다.

  • Biotechnology is often described as the 'exploitation of biological processes for industrial purposes'. The last twenty years have seen phenomenal growth in this industry. The 21 century promises to see further advances in the field. However, since the cost of research is high, and the potential returns are linked to exclusivity, intellectual property protection is critical to this burgeoning industry. Without protection such investments in R&D would not be made and, the benefit that BT-related development are expected to bring, would not occur. BT industry are eager for high technology, and the technology must be transferred to a corporation from a research organization. In order to be successful, it is important that scientist must be directed toward R&D outcome beyond performance assessment. The process to gain a outcome involves multiple steps to turn the idea into the profit, and intellectual property issues are considered into the critical factors to affect the quality of R&D. The management of Intellectual property is very important in R&D. However, According to the survey conducted by KIIP (Korea Institute of Intellectual Property) and KOSEF (Korea Science and Engineering Foundation) in 2006, it is estimated the ability to treat Intellectual property is not sufficient because 82.5% of the respondents have not received an education. Governmental Support is needed to prompt systematically the ability of intellectual property management through education and consulting.

  • Intellectual Capital, a valuable intangible organizational asset, is primarily linked to a company's financial performance and is divided into three categories: human, structural, and relational capital. This paper investigates the impact of intellectual capital on the financial performance of selected Pakistani companies in the Information and Communication sector, as this sector is heavily reliant on intellectual capital. The data for 11 firms was gathered from the State Bank's Financial Statements Analysis of Companies Listed on the Pakistan Stock Exchange from 2015 to 2020. Pulić's (2004) Value Added Intellectual Coefficient (VAICTM) has been used to assess a company's IC efficiency. VAICTM and its components, the efficiency of intellectual capital, and the efficiency of capital employed are calculated. Financial performance is measured through return on assets, return on capital employed, and asset turnover ratio. Multiple regression, fixed-effect, and random-effect Panel Data estimation are used in the empirical study. The findings suggest that intellectual capital efficiency has a large impact on major profitability metrics, but little effect on company productivity. It can be inferred from the results that the companies must invest in advanced technology, the latest machinery, and well-equipped offices to improve financial performance and productivity and gain a competitive advantage.

  • The 21/sup st/ century is a society based on knowledge, so in economic activities, it has emphasized the importance of information such as intellectual property or intangible asserts. Especially, according to the agreement on trade related as parts of intellectual property rights in WTO, it is used as the method of commercial entente and monopoly for intellectual property in an advanced nation. For this reason, WIPO and UNESCO discussed a complement for intellectual property on the foundation of traditional knowledge such as traditional knowledge (TK), genetic resources (GR) and traditional cultural expressions (TCE, folklore). Korea has a lot of knowledge falling under TK, GR, and TCE because of the long history of the country. In the case of traditional medical care, it has been used in the public health system. It is hard to apply these rights to traditional medical care of Korea because the laws of intellectual property have been established under the ideas of western culture. It is necessary to improve the classification system of traditional knowledge and patents. In the patent classified system of IPC, it needs to be related to the research between the classified system for massive technology and the classified system for traditional clinic technology.

  • Objectives : In the WIPO conference about the protection of intellectual property for traditional knowledge (TK) and genetic resources (GR), there was a demand concerning the necessity of recognizing the invention of TK and GR and the foundation of a related database. Methods : In the standard of the foundation of a database, the content and resource identification standards, the technological standards and the security and transmission standards were discussed. In a decision on intellectual property, it means the protection and recognition as a technology precedent of the materials of the database. Results : Massive material on traditional medical care technology in Korea has existed in many areas. However, it is hard to make a database because it is difficult to organize and find the data. In addition, a database demanded by WIPO is not only the material of images or texts of simple technology information, but also the use of patent decisions about traditional knowledge technology and the public sharing of information in related areas. A traditional medical care database would consist of the core of a subject and the related areas. The core part is the medical herb resource and Oriental clinical technology. Conclusions : These are necessary to detail the kind of medicines and prescriptions, their use, and their processing. In the related areas, it needs to detail PIAS and clinical data in regarding the industrialization. These DB have to protect the TK and the GR of Korea.

  • Clothing is intimately intertwined with daily lives as every individual relies on it. The pervasive issue of plagiarism in the fashion industry has led to an increased demand to protect intellectual property rights. Currently, studies on the protection of fashion design intellectual property rights in China remain in the exploratory stage and warrant further investigation. This paper addresses the issue in two parts. The first part contains an analysis of the theoretical foundation for the protection of fashion design copyrights. It is further divided into three subsections. The first subsection primarily examines the concept of copyrights and laws. The second subsection focuses on the concept of fashion design copyrights and laws. The third subsection analyzes copyright laws concerning fashion designs in China. The second section offers an analysis of infringement cases involving fashion designs published during the Baiyi Cup Intellectual Property Case Summary Writing Competition held in China in 2023. It outlines the shortcomings of the current Chinese copyright laws regarding the protection of fashion designs, and proposes measures for improvement. This study argues that the institutional framework for intellectual property rights in the Chinese fashion industry should align with practical considerations and explores suitable legal regulations and how they relate to specific circumstances in China. Besides refining the legal framework, fashion designers and enterprises must take measures to entablish the intellectual property rights of their clothing brands.
