Drug approval-patent linkage is the practice of linking drug marketing approval to the patent status of the originator's product and not allowing the grant of marketing approval to any third party prior to the expiration of the patent term unless by consent of the patent owner. Article 18.9.5 of Korea-US Free Trade Agreement requires that Korea introduce the linkage system in drug marketing approval. However, Korea is unfamiliar with the linkage system. In addition, there have been lots of arguments over the impacts of this system on Korean pharmaceutical industry and pharmaceutical market in the future. This report investigated the linkage systems of the US and Canada. The US and Canada have implemented drug approval-patent linkage system since 1984 and 1993, respectively. Both countries have patent lists for drug approvalpatent linkage on which originators are required to list patents on substance, product, and use of their drugs. Generic or follow-on drug applicants must contain a certification regarding each patent listed that relates to the referenced drug. If the patent holder files suit for patent infringement within 45 days of notice of application, drug approval is not allowed for several months - 30 months in the US and 24 months in Canada. Both countries have amended their systems after having experienced unexpected results such as listing improper and additional patents, multiple patent litigations and delayed generic entries. After reviewing the US and Canada's experiences, we suggested three principles needed in implementing the system: protecting patent holder's right; promoting generic drug development and marketing; monitoring the process and the effect of the system.

Since the positive listing system for prescription drug reimbursement has been introduced in Korea, the number of pharmacoeconomic evaluation studies has increased. However it is not clear if the quality of pharmacoeconomic evaluation study has improved. Due to the lack of randomized clinical studies in Korean health care setting, Korean economic evaluation studies have typically integrated the local cost data and foreign clinical data. Therefore methodological issues can be raised in regard to data coherence and consistency. But the quality of data was not questiened and the potential bias has not been investigated yet. Even though changes in policy have encouraged the undertaking of pharmacoeconomic evaluations, there is few public-side funding for validation study of cost-effectiveness models and data. Several companies perform economic evaluation studies to be submitted on behalf of their own products, but do not want the study results to be disclosed to the academic community or public. To improve the present conduct of pharmacoeconomic evaluations in Korea, various funding sources need to be developed, and, like other multidisciplinary areas, the experts in different fields of study should collaborate to ensure the validity and credibility of pharmacoeconomic evaluations.

The study reported here is a part of the Korean Science Education Database (SEDB) project, a long-term effort to improve science education by providing educational information to science educators. The purpose of the SEDB project is to improve access to science resources available to teachers, students, parents, and others. Three educational database have been investigated and discussed in depth. The Educational Resources Information Center (ERIC) that is the largest education database in the world and the Eisenhower National Clearinghouse for Mathematics and Science Education (ENC) that is creating an easy-to-use catalog of mathematics and science curriculum materials have been investigated on the aspect of system and operation. The pilot form of the SEDB developed in this study has committed itself to reaching audiences that include practitioners and policymakers. The SEDB should be a collection of the most up-to-date and comprehensive listing of science curriculum materials in the nation, because educators need better access to the best instructional materials and programs to continually improve science education our nation's science. The researchers recommend the practical tips for developing an effective science education database.

The purpose of this paper is to review the quality of corporate governance from the prior empirical literature. This study finds that most of the researchers developed the self structured corporate governance index and few researchers used the corporate governance index provided by rating agencies. This study also finds that there is no uniform basis to measure the corporate governance quality and observed the variation in terms of overall and individual attributes of corporate governance; sub-indices of corporate governance; scoring system; weighted and un-weighted method; statistical method; time period; financial and non financial companies; code of corporate governance; listing requirement; disclosure practices; legal environment; firms characteristics; and country perspective. This study also observed that overall corporate governance quality is very low in most of the studies and even quality of corporate governance varies in the firms within the same country. This study recommends that the boundary of corporate governance quality should be defined based on the agreed set of rules and regulation, code of governance and practices. This study also suggests that the regulator and policy makers should more emphasize on code of corporate governance and regulatory framework and monitoring to improve the quality of corporate governance.

Information science is the study how in formation is transferred and all the intermediate steps of collecting, organizing, interpreting, storing, retrieving, disseminating and trans foming information. Professional education means the transfer of knowledge, the development of cognitive abilities and the infusion of professional attitudes. Training may be defined as practice-based instruction in the development and use of professional skills. Each is affected by the confluence of social, economic and technological realities of the environment where the learning takes place. We have witnessed controversy about methods of curriculum revision and change. Should information science courses be added to the traditional library science curriculum or should the new approaches be integrated within the subject matter of each individual course? The article is based upon the assumption that education for librarianship is at a turning point. To provide this information, 25 curricula of colleges and universities were analysed to assist in the study. Also 32 information professionals were asked to assist in the study. In the experimental part of this study, curricula based on the education and training of library and information profession als were examined. The most frequently offered compulsory course 'Introduction to Information Science' exposes students to a new way of looking at library and information problems. Information retrieval, library automation, computer programming, data processing, indexing and abstraction, communication, system analysis has offered. These indicate a curriculum slowly shift from traditional librarianship to an emphasis on computerization and automation. Also from a questionnaire listing 58 events might influence library and information science education.

Purpose - The purpose of this paper is to get a clear concept about intellectual capital and reports on intellectual capital in different entities based on the literature review. Research design, data, and methodology - This study was mainly written in a way of descriptive research. The current studies deal with the theoretical and reporting aspects on intellectual capital. Thus, this research is developed on the basis of previous descriptive and empirical research papers. Results - This study finds that intellectual capital is the combination of human capital, structural capital and relational capital but there is no unique measurement system or process to define intellectual capital. The findings also indicates that the measurement for intellectual capital varies based on the measurement process, time period, firms, industries and country to country perspectives. It can be also observed that firms have the tendency not to disclose the intellectual capital information. Conclusions - This study recommends that intellectual capital should be presented in a fixed format and human, relational and structural capital should be included as intellectual capital. Additionally, it suggests that mandatory requirement of legislation, effective corporate governance mechanism and stock exchange listing requirement might increase the quality of intellectual reporting.

DNP3(Distributed Network Protocol) is one of the most representative protocols which is used in SCADA(Supervisory Control and Data Acquisition) system. IEC 62351 is listing the integrity, confidentiality, availability and non-repudiation or accountability as the security requirement. However, IEEE Std. 1815 that is DNP3 standards does not define a mechanism for non-repudiation or accountability. In this paper, we propose a non-repudiation of origin technique about the sender of critical ASDU and implement the proposed scheme using software such as OpenSSL and SCADA source code library.

Mobility and cloud platform have become the dominant paradigm to develop web services dealing with huge and diverse digital contents for scientific solution or engineering application. These two trends are technically combined into mobile cloud computing environment taking beneficial points from each. The intention of this study is to design and implement a mobile cloud application for remotely sensed image fusion for the further practical geo-based mobile services. In this implementation, the system architecture consists of two parts: mobile web client and cloud application server. Mobile web client is for user interface regarding image fusion application processing and image visualization and for mobile web service of data listing and browsing. Cloud application server works on OpenStack, open source cloud platform. In this part, three server instances are generated as web server instance, tiling server instance, and fusion server instance. With metadata browsing of the processing data, image fusion by Bayesian approach is performed using functions within Orfeo Toolbox (OTB), open source remote sensing library. In addition, similarity of fused images with respect to input image set is estimated by histogram distance metrics. This result can be used as the reference criterion for user parameter choice on Bayesian image fusion. It is thought that the implementation strategy for mobile cloud application based on full open sources provides good points for a mobile service supporting specific remote sensing functions, besides image fusion schemes, by user demands to expand remote sensing application fields.
