불리한 출판환경에서 악전고투하고 있는 학술출판사들이 자구책 마련에 나서고 있다. 번역자가 적극적으로 저작권 계약 중재에 나서 유리한 조건을 이끌어내거나, 외국정부와 공익재단의 지원을 받아 출간하는 경우, 또 인세 후불제와 개별적 노력이 학술출판의 맥을 이어가고 있다.

One of the potential advantages of computer-based instruction is individualization of instruction. However, this goal has not been fully realized in practice, due largely to limitations of natural language understanding and to combinatorial explosion. It is nonetheless possible to develop CAT(Computer- based Adaptive Testing) Programs which can adapt to students, depending on their performance, by adjusting the length of computer-based tests. The number of questions can be significantly reduced for many individuals, while mastery and nonmastery decisions remain highly accurate. In this paper, We design and implement a Diagnosis System using SPRT(Sequential Probability Ratio Testing). This system supports multimedia object, client/server environment, indvidual feedback, multi-SPRT and maintain student model for individualization of instruction. besides, this system measures coefficient alpha of each problem.

It's difficult to find efforts for individualization other than suggesting simple, branching level learning materials among the developed courseware. The reason is primarily attributed to the facts that the courseware itself is not flexible, a fixed structure which is not reusable, and numerous costs and time should be consumed to develop one. In the same context of the appearance of the object-oriented concept in the method of software development, the concept of 'learning object' has appeared in the development of courses and contents, paving the way toward the possibility of designing versatile courses through the learning object. In the learning object-based course design, however, it still has similar shape and structure to the existing courseware, and the effort to realize the individualized learning by utilizing the learning object is not sufficient, as well. In this study, I suggest a outlined learning object model which can support the individualized learning by expanding the existing learning object, and based on th is model. design a instructional model that can show an individualized learning path, based on the ADDIE model.

무선 휴대 단말기를 이용한 음성통신에 있어서 CDMA 망 기반의 음성통신뿐만 아니라 대표적인 무선망인 와이파이, 와이브로망 기반의 음성통신 서비스를 지원하기 위한 기술 개발이 이루어지고 있고, 이를 지원하는 다양한 단말기가 현재 출시되고 있다. 이러한 추세에 따라 산업현장에서 실시간 그룹통신을 지원하기 위해 사용되는 무전기 및 TRS 등의 시스템을 대체할 수 있는 IP 기반의 그룹통신 기술의 수요가 증가하고 있다. 그러나 현재 대부분의 VoIP 지원 단말기는 1:1 개별 통신을 주요 기능으로 지원하고 있으며, 1:N 실시간 그룹통신에 대한 지원은 미흡한 상황이다. 이러한 문제를 해결하기 위해 본 논문에서는 SIP 기반의 그룹통신 시스템 구현 방법에 대해 제안한다.

This paper proposes a state machine design methodology in which an interactive robot that mimics discrete trial training (DTT protocol) can support social interaction training for children with autism. The robot applied to social interaction training uses the response to the provided training stimulus as a quantitative indicator by processing the data received from the sensors measuring the behavioral response of the child. In this process, the state machine is used as information that classifies the state of the acquired data and provides the subsequent stimulus for DTT protocol. Through the joint attentional training, it can be used as evidence-based treatment information by quantitatively classifying the data on the number of sustainable and DTT protocol and the child's response, as well as the current reaction status of the child to the observer performing remote monitoring. At the same time, it was confirmed that it is possible to properly respond to misrecognition situations.

This paper suggests a genuine method to estimate the agglomeration effects of Industrial Cluster focusing on the FOODPOLIS (KOREA NATIONAL FOOD CLUSTER). In this study, we will focus on two issues related to the clustering effect. First, Clusters affect productivity, and a cluster allows companies to operate more productively in inputs; accessing technology, human resource, information, services, and needed institutions. Second, we assume that the effects of Industrial Cluster can be estimated from measurement on differency of an added value between large-scale enterprises and smaller ones. To demonstrate effectiveness of this approach, the estimated effect was compared with that from the related study (A Mini-Cluster). Industry Clusters have been considered as critical factors for regional competitiveness and economic revitalization. For this, the government and local government should find a way and strategy to provide useful contents that can attract the participation of firms and to secure strategic positioning and competition strategies.

Unlike traditional environmental problems, current environmental problems occur due to by complex reasons. These complexities highlight the importance of precise spatial based analysis and expeditive use of environmental information when an environmental problem arises. However, the traditional environmental information has many problems because they are mainly numerical based and scattered in various systems. To overcome these problems, providing integrated environmental spatial information is important. Thus, a research was conducted on establishing national environment atlas system and its implications for policies. Firstly, this study selects 275 out of 2,701 materials and information from Ministry of Environment and related organizations. Secondly, total 64 thematic maps specific business support are Produced to support establishment and implementation of environmental policies. In addition, the produced thematic maps are privatized. Thirdly, the study analyzes total 17 systems and environmental thematic maps of Ministry of Environment and relevant organizations to connect the information on the business support thematic maps. As a result, 1,314 applicable spatial information and 39,331 applicable database based on spatial information based are selected, and a standardization plan is established. Fourthly, the study suggests a stepwise implementation plan for developing a national environment atlas system. The development of national environment atlas system will help establishing an environmental policy based on more relevant and accurale information.

This study is aimed at proposing a new type of ubiquitous decision support system (u-DSS) portal which is embedded with two important mechanisms like an intelligent ontology management module (i-OMM) and multi-agent coordination mechanism (MACM). The proposed portal provides timely decision support to the involved decision entities (represented as agents) by taking advantage of the two mechanisms embedded on the portal. The most important virtue of the proposed portal is that it can resolve two problems such as semantic discordance and data confliction which are occurring very often in an ubiquitous computing environment. Frequent requests of revising the already established decision information due to the rapid changes in decision entities' requirements require the extremely flexible and intelligent u-DSS vehicle like theproposed mechanism. In this sense, the i-OMM is designed to provide support to solving the semantic discordance in the way that the i-OMM virtually integrates ontology view (IOV) to integrate heterogeneous ontology among the agents engaged inubiquitous commerce situations. Then the i-OMM sends the IOV to the MACM to resolve the conflicts among the involved agents. The proposed u-DSS portal was applied to the u-fulfillment problem in which all the involved decisionagents need their own requirements to be satisfied seamlessly and timely. The experimental results show that the proposed u-DSS portal is very robust and promising in the field of u-DSS and context modeling.

To efficiently manage data varying over time and process event driven transactions, some of the various database applications recently emerged require database systems supporting both a temporal data model and active rule processing. There has been much progress in independent research on temporal databases and active databases, but studies on databases which support both functions, have been rare. In this paper, an active temporal rule model supporting both active rule processing and temporal data model is presented with its rule expression language. This active temporal rule model contributes to the active function extension of the temporal database, and to establishing the concept of data access events which refer temporal attributes of data in active rules.
