While Internet promises ubiquitous access, it also creates a fundamental challenge to the traditional ownership toward digital assets traded in e-commerce market. Sharing digital information freely through shared networks leads to many untapped business opportunities, but uncontrolled digital asset transaction undermines many electronic business models. Thus, in this Internet age, proper protection and safe delivery of Intellectual Property (IP) and its representation as digital assets would be a crucial ingredient of building trust in upcoming e-business environment. In this paper, we give a general structural diagram of Intellectual Property Management and Protection (IPMP) and implement an IPMP prototype based on the RSA encryption algorithm and XrML (eXtensible rights Markup Language) WORK tags to show how proper protection and safe delivery of the intellectual property is achieved. This study concludes that IPMP mechanism may contribute significantly to the volume and quality of e-commerce market.

This paper attempts to investigate to what extent English proficiency can boost international trade in services. To achieve this purpose, this paper estimates the determinants of services trade including language variables with the aggregated and disaggregated data for nine different subsectors of OECD countries. The empirical tests are based on a theory-based gravity model derived from Anderson and von Wincoop. The findings show that English proficiency has a significant influence on services trade, while other languages such as French and German have only weak and mixed effects. In particular, communication, financial, commercial, insurance, and business services are revealed to be the most impacted by the level of English proficiency. The results imply that governments can use their English policies to promote international trade in services.

In the age of global communication, more human exchange is extended at the grass-roots level. In the old days, language policy and language planning was based on one nation-state with one language. But high waves of globalizaiton have allowed extended human flow of exchange beyond one's national border on a daily basis. Under such circumstances, homogeneity in Japan may not allow Japanese to speak and communicate only in Japanese and only with Japanese people. In Japan, an advisory report was made to the Ministry of Education in June 1996 about what education should be like in the 21st century. In this report, an introduction of English at public elementary schools was for the first time made. A basic policy of English instruction at the elementary school level was revealed. With this concept, English instruction is not required at the elementary school level but each school has their own choice of introducing English as their curriculum starting April 2002. As Baker, Colin (1996) indicates the age of three as being the threshold diving a child becoming bilingual naturally or by formal instruction. Threre is a movement towards making second language acquisition more naturalistic in an educational setting, developing communicative competence in a more or less formal way. From the lesson of the Canadian immersion success, Genesee (1987) stresses the importance of early language instruction. It is clear that from a psycho-linguistic perspective, most children acquire basic communication skills in their first language apparently effortlessly and without systematic and formal instruction during the first six or seven years of life. This innate capacity diminishes with age, thereby making language learning increasingly difficult. The author, being a returnee, experienced considerable difficulty acquiring L2, and especially achieving native-like competence. There will be many hurdles to conquer until Japanese students are able to reach at least a communicative level in English. It has been mentioned that English is not taught to clear the college entrance examination, but to communicate. However, Japanese college entrance examination still makes students focus more on the grammar-translation method. This is expected to shift to a more communication stressed approach. Japan does not have to aim at becoming an official bilingual country, but at least communicative English should be taught at every level in school Mito College is a small two-year co-ed college in Japan. Students at Mito College are basically notgood at English. It has only one department for business and economics, and English is required for all freshmen. It is necessary for me to make my classes enjoyable and attractive so that students can at least get motivated to learn English. My major target is communicative English so that students may be prepared to use English in various business settings. As an experiment to introduce more communicative English, the author has made the following syllabus design. This program aims at training students speak and enjoy English. 90-minute class (only 190-minute session per week is most common in Japanese colleges) is divided into two: The first half is to train students orally using Graded Direct Method. The latter half uses different materials each time so that students can learn and enjoy English culture and language simultaneously. There are no quizes or examinations in my one-academic year program. However, all students are required to make an original English poem by the end of the spring semester. 2-6 students work together in a group on one poem. Students coming to Mito College, Japan have one of the lowest English levels in all of Japan. However, an attached example of one poem made by a group shows that students can improve their creativity as long as they are kept encouraged. At the end of the fall semester, all students are then required individually to make a 3-minute original English speech. An example of that speech contest will be presented at the Convention in Seoul.

Rapid changes in the economic, social and academic environments often provide opportunities to develop new and advanced technologies. In China, recent literature on the role of universities suggests that university-industry linkages (UILs) play a substantial role in the development of high-tech industries. Since 1979 when the country became more open and underwent economic reform, Chinese central authorities, local governments, and universities have continued to set up various science and technology (S&T) policies to stimulate UILs, contributing to China's technological progress and economic growth. This study examines the role of S&T policies on UILs such as transfer of technology, joint research, and spin-off creation with a particular focus on Nanjing University (NJU) in Jiangsu Province. Nanjing has over 53 universities, ranking it behind Beijing and Shanghai in terms of S&T and higher education opportunities. By adopting "institutional methodology," this study contends that UILs not only benefit universities and industry but also society in terms of job training, consulting activities, joint research, R&D results commercialization, patent licensing, new business creation, and other aspects. Finally, we suggest that the Chinese experience, though with some problems, might enhance our understanding of how to stimulate UILs through the arrangement of various S&T policies.

The study explores the way professors working in a private university in Korea perceive the recent English-medium instruction (EMI) frenzy in Korean higher education (HE) and the way they respond to its manifestation at their institution. Working within a qualitative research paradigm (Merriam, 2009), I gathered data primarily via one-time semi-structured interviews with ten participants who have offered or are offering EMI at the time of data collection and used a qualitative data analysis method. The findings illustrate that the professors view external factors residing outside individual universities, such as the college rankings and the university evaluation parameters, as the principal drive behind the current EMI boom in Korean tertiary education. Acknowledging the importance of strengthening the international competitive edge of Korean HE in the global era, the professors perceive the EMI policy positively expecting it to be beneficial for both students and institutions. They, however, problematize the blind acceptance of EMI policy and externally forced EMI expansion movement in Korean HE, which they believe will lower the standard of the academic experience of students. Experiencing first-hand the inadequate manifestation of the EMI policy at their university, the professors claim that a systematic long-term implementation plan and context-suitable approaches should be taken at both the national and institutional level for successful future EMI implementation and expansion efforts.

최근 몇 년 동안 이동 에이전트(Mobile Agent) 기술은 분산 처리 시스템(Distributed Processing System)의 새로운 패러다임(Paradigm)으로 많은 관심이 되어왔다. 이동 에이전트는 통신망 노드에서 노드로 이주 가능한 자율적인 객체이다. 그러나, 통신망에 연동된 호스트(host)나 노드 결손 등으로 인해 이동 에이전트는 계속 처리할 수 있는 다른 노드들이 있을 지라도 무한 대기하거나 파괴될 수 있다. 이를 위해서, 본 논문은 이동 에이전트의 이주를 보장하기 위한 경로 재조정과 후위복구 기법을 통한 효율적인 이주 정책을 제안한다. 제안된 이주 정책은 가능한 한 자율적으로 이동 에이전트의 이주 신뢰를 제공하고, 자바(Java) 언어로 개발된 이동 시스템 모델인 MOS에서 이를 구현한다.

For ease of use and access, web browsers are now being used to access and modify sensitive data and systems including critical control systems. Due to their computational capabilities and network connectivity, browsers are vulnerable to several types of attacks, even when fully updated. Browsers are also the main target of phishing attacks. Many browser attacks, including phishing, could be prevented or mitigated by using site-, user-, and device-specific security configurations. However, we discovered that all major browsers expose disparate security configuration procedures, option names, values, and semantics. This results in an extremely hard to secure web browsing ecosystem. We analyzed more than a 1000 browser security configuration options in three major browsers and found that only 13 configuration options had syntactic and semantic similarity, while 4 configuration options had semantic similarity, but not syntactic similarity. We: a) describe the results of our in-depth analysis of browser security configuration options; b) demonstrate the complexity of policy-based configuration of web browsers; c) describe a knowledge-based solution that would enable organizations to implement highly-granular and policy-level secure configurations for their information and operational technology browsing infrastructures at the enterprise scale; and d) argue for necessity of developing a common language and semantics for web browser configurations.
