정보생산을 촉진하는 새로운 형태의 사이버공간이 나타나면서 지식의 창출과 지식을 얻는 형태가 변화하고 있다. 최종사용자에게 웹 애플리케이션을 제공하는 컴퓨팅 플랫폼인 web 2.0의 도입으로 손쉽게 자신이 필요한 정보를 분류할 수 있는 웹 컨텐츠가 활발히 제공되고 있으며 제공된 컨텐츠를 활용하여 수많은 정보 속에서 자신만의 보석을 찾아 손쉽게 지식을 쌓아 관리를 하고 있다. 이러한 지식공유서비스는 무분별한 정보, 중복된 지식, 그리고 단순한 관리로 인해 자신이 원하는 지식을 얻기란 쉽지 않은 것이 사실이다. 본 논문에서는 온라인상의 정보를 탐색하기 위해서 인터넷을 이용하던 네티즌들이 정보생산자로서 참여하는 공간으로 등장한 '지식공유서비스'를 기반으로 지식 창출 및 관리자로서 시니어를 활용하여 지식의 수용자로서 유아들을 위한 NIE (News In Education) 활용 교육 체계를 제안한다. 뉴스는 유아부터 성인까지 활용될 수 있는 좋은 교육 자료로서 NIE를 통하여 사고력, 논리력, 표현력, 창의력 등 여러 영역에 걸친 능력을 향상시킬 수 있다. 특히 유치원이나 학교의 교과과정에 맞추어 이러한 능력들을 더욱 배가 시킬 수 있다는 점에서 NIE가 더욱 각광받고 있다. 본 연구는 미디어 융합의 결과로 인터넷 뉴스를 활용해 생활과 분리되지 않은 통합교육을 할 수 있는 SCORM 기반의 유아용 콘텐츠를 생성하여 유아 교육에 활용하고자 한다. 또한, 유아용 NIE 교육 콘텐츠는 시니어들을 NIE 강사로 양성하였을 때 학습 자료로도 활용된다. 시니어들을 NIE 강사로 양성함으로써 시니어의 일자리 창출 및 지역사회 통합과 1세대인 여성시니어와 3세대인 아동 간의 세대통합을 이끌어 낼 수 있도록 하는 것에 목적을 두고 시니어 NIE 콘텐츠를 생성하고자 한다. NIE에 생성되는 지식을 생성하고 관리하기 위한 지식 솔루션으로 위키의 기능을 추가하여 개발하고자 한다. 위키를 사용하므로 개별적으로 존재하던 지식을 공동의 지식으로 공유할 수 있으며 의견을 하나로 통합하는 과정에서도 유용하게 사용될 수 있을 것이다. 위키를 이용한 시니어 NIE 콘텐츠에서는 교수 학습 계획안 및 NIE 아이디어를 공동 작업을 통하여 효율적으로 지식을 생성할 수 있으며 여러 사람들이 여러 단계를 거치면서 하나의 정제된 지식을 생성하게 되므로 양질의 교수 학습 계획안이나 NIE 아이디어를 창출할 수 있을 것이다.

The specific gravity is heavily focused on the service industry in the economic development of domestic and overseas in these days. This will be predicted to increase persistently in the future society. Therefore the franchise system has been diffused as one of a management methods for these service industry. The franchise system is an advanced country's circulation system which has been populated in an advanced country. After the opening of circulation market, rapid growing trend has been showing on foreign country's popular brands in the local domestic market. So the franchise system has been largely focused on among the domestic manufacturing and the circulation companies. This study is to review how the management characteristics(headquarters' supports, communication, menu development, compensation) will affect the fairness perception of franchisee owner. The results of my study are as follows; It appeared that communication, menu development and compensation affected all the distribution fairness and the procedure fairness affirmatively.

The concept of Web 2.0, which means that internet users are producers and also consumers is evolved according to the development of web service technology. In the Web 2.0 space, the enormous amount of web contents are produced using many social web services. Proactive display system supports various types of users's web contents. Unfortunately, private web contents sharing facility is imperfect to date. In this paper, we develop a proactive display application which identifies people, displaying their social contents such as blogs and open cafes through wide display devices or multi-media players in physical spaces. For this, we develop a social contents presentation server where users can register their profiles and information on the social contents to be shared through the developed application. Also, we develop a social contents presentation client that proactively identifies the user in close proximity and displays the user's social contents through an intuitive user interface in physical spaces. In addition, we develop an on-the-spot feedback service which supports posting various types of replies and an on-the-spot scrap service which specifies direct sharing of the contents through the intuitive user interface.

This study looked at the blockchain technology as an ecosystem side and examined the role of each component. In this study, the blockchain ecosystem is a network structure in which members share and collaborate with each other in order to create new value(service) based on the distributed ledger. Hence compare to bio-ecosystem, the components of blockcahin ecosystem are consists of service providers(producer), service users(consumer) and the distributed ledger owners(decomposer). Distributed ledgers, who act as decomposers in the blockchain ecosystem, play an important role. In order to maintain and activate the value of the blockchain ecosystem, the ecosystem can be effectively operated by constructing an environment in which the distributed ledger owners can handle effectively. This will help us to understand the relationship between ecosystems and not only to contribute to the study but also to activate the blockchain ecosystem. The limitations of this study are based on exploratory research, and specific discussion is needed based on objective data.

This study investigated the carbon offset project activities as the activities of producing commodities by a case study on the Korean Clean Development Mechanism(CDM) industry. This study draw the networks of Korean CDM industry by extracting major agents and surrounding agents and by analyzing the characteristics of the linkages. The project participants owning the CDM projects hires CDM consultancies and designated operational entities(DOEs). The technical knowledge for carbon emission reduction made links between project participants and the CDM project operational knowledge made links between project participants and CDM consultancies. Links between project participants and DOEs are affected by social and geographical proximities. The value of the knowledge for CDM industrial activities determined the role of agents and type of linkages. The agents with the irreplaceable knowledge could be a project conducting firms. The agents without it became outsourcing contractors.

Information systems, which support information security functions such as CALS and EC systems, should have cryptographic functions for information in order to storage and communicate securely. Additionally, including recovery of lost keys, lots of cryptographic keys should be securely managed. In this paper, we present some results of development of a key recovery system for recovery of encrypted data. The proposed system, in a type of key encapsulation approach, confirms to NIST's RKRP(Requirements for Key Recovery Products) that is a defecto international key recovery standard, as well as CC 2.0 that is a international security evaluation criteria. A message sender secretly choices two or more key recovery agents from a pool of key recovery agents. The key recovery information is generated by using the recovering key, random keys and public keys of the chosen agents. A message receiver can not know which key recovery agents are involved in his key recovery service. We have developed two versions of prototype of key recovery system such as C/Unix and Java/NT versions. Our systems can be used for recovery of communicating informations as well as storing informations, and as a new security service solution for electronic commerce service infrastructures.

The purpose of this study is to review research trends and issues of economic geography in Korea for the last fifty years by sub-fields of agricultural geography, industrial geography, commercial and service geography, and transportation geography. Research in Korean economic geography has progressed significantly in terms of the scope and the number of papers published during the last a half a century. Agricultural geography was a leading field of economic geography in Korea before mid-1970s. Since the mid-1970s, however, agricultural geography has turned over the leading role in economic geography to industrial geography. Classification and structure of agricultural region has been the most popular research theme in Korea, even though diverse topics has been dealt in the research of agricultulal geography in Korea during the last fifty years. In recent years, emphasis is given to study on the dynamics of agricultural region and regional differentiation of part-time farming. It is suggested that the future issues of research in agricultural geography in Korea are agricultural restructuring and changes in agricultural space under the WTO system, changes in rural area and agricultural region with the progress of informatization, changes in agricultural structures and rural society by the increase of part-time farming, governments agricultulal policy and its impacts, competitive advantages of Korean agricultulal products, and environmental impacts of agricultural restructuring. Research in industrial geography has remarkably progressed since the 1980s. Locational changes, regional industrial structure and formation of industrial region were the major topics of interest in the research of industrial geography in Korea before 1980. Since the early 1980s, in addition to the topics which were interested in before 1980, changes of industrial organization and industrial location, changes of production systems and industrial space development of high technology industries and science parks, industrial restructuring and regional economy, foreign direct investments, industrial linkages and industrial districts, and industrial policy and regional development have been the major research themes of industrial geography in Korea. Considerable number of papers has been published both in Korean journals and in foreign journals during this period. Considering global changes in the organization of industrial space, future research should be more focused on firms strategy for regaining competitive advantages, local and global perspectives of industry, industry and environmental changes, in addition to the topics which have been dealt in recent years. Research in commercial and service geography and transportation geography was negligible in Korea before the late 1970s. These two sub-fields in economic geography have begun to develop since 1980s. Periodic markets, structure of commercial area, and distribution of products were the major topics of interest in the 1980s in the commercial and service geography in Korea. In the 1990s, however reserch in producer services has been active with growth of producer services in Korean economy. It is suggested that regional changes with progress of informatization and technology, changes of international trade and regional changes, development of efficient distribution system, role of producer services in regional development, and network of producer services are the major issues to be studied in the future in the field of commercial and service geography in Korea. Commuting, distribution of products, and transportation networks have been the major topics of research in transportation geography in Korea. Diverse quantitative techniques have been applied in the most of the researches in transportation geography. It is required that future studies in transportation geography should also focus on societal and behavioral issues, policy issues regional impacts of new transportation facilities, an analysis of transportation system at the global or international level. Since the 1980s economic geography in Korea has considerably progressed with publication of papers and books. The progress can be regarded as successful in quantitative aspect, but not in quantitative aspects. For the development of Korean economic geography in both quantitative and qualitative aspects, it is necessary to promote international collaborative researches and interdisciplinary cooperations. Attention should also be given to the research on changes in competitive advantages and economic restructuring, changes of economic space with the development of high technology and the progress of informatization. economic development and culture. and foreign regional studies.
