  • Esterel is an imperative synchronous language well-adapted to control-intensive systems. When an Esterel program is translated to a circuit, the synchronizer of a parallel statement may be executed more than once in a clock; the synchronizer is called schizophrenic. Existing compilers cure the problems of schizophrenic parallel synchronizers using logic duplications. This paper proposes the conditions under which a synchronizer causes no problem in circuits when it is executed more than once in a clock. In addition we design a detection algorithm based on those conditions. Our algorithm detects schizophrenic parallel synchronizers that have to be duplicated in Esterel source codes so that compilers can save the size of synthesized circuits

  • The Grid is new infrastructure to provide computing environment for grand challenge research by sharing large-scale resources. Currently the Globus becomes a de facto standard middleware to construct Grid and supports core services such as resource management, security, data transfer, information services, and so on. However, it still needs more works and researches to satisfy requirements from various grid applications. A workflow management is becoming a main service as one of the important grid services for complex grid applications. We propose a Meta Scheduling Framework (MSF) in this paper. The MSF provides a XML-based Job Control Markup Language (JCML) for describing information and procedures of grid applications, and a workflow management service for scheduling the job using the JCML and for processing the job effectively.

  • This paper aims at overviewing Korean fisheries profile with a view on why Korean fisheries need marine ranching program as a new fisheries paradigm - a community-based co-management approach and drawing some policy implications from the advanced experience in fisheries. The aims of community-based co-management approach as a planned approach can be set out under the planning objectives of efficiency and equity. In this context Tongyeong marine ranching program is an important government-sponsored pilot enterprise. Experiences in the advanced fisheries such as Canadian Snow-Crab case suggest that in order to be successful for marine ranching be successful it is necessary that (i) there should be high-value species, (ii) property right should be established, (iii) there should be the reasonable number of participants involved, (iv) the participants and the government should be able to share resource enhancement/management/utilization responsibilities and associated fisheries management expenses. Among these, management cost sharing based on the practical partnership between fishing communities and government is of particular importance because the government must have a full responsibility for all ranching program expenditure unless revenues sufficient to guarantee reasonable income and to share management cost are generated from the ranching business.

  • The purpose of this study is to describe the information environment of ST information users in Korea by examining their needs and satisfaction for documents. Comparison was made between the statistics of KISTI DDS and NACSIS-ILL document copy service, and data from the survey conducted for KISTI's ST information users in 2001 were analyzed. Findings include the low demand for documents delivery, low success rate in obtaining documents from domestic institutions, including KISTI, relatively high reliance on foreign DDS institutions, and difficulties in getting documents with speed, timeliness, and cost-effectiveness. It seems urgent to implement the strategic plans for more comprehensive and well-organized collection development and resource-sharing, and improvement of DDS.

  • A Vehicular Ad-Hoc Network (VANET) is a form of Mobile ad-hoc network, to provide temporary communications among nearby vehicles. Mobile node of VANET consumes energy and resource with participating in the member of network. Some node tends to have a selfishness to place one's own profits above cooperation with others. As result of selfish node, it reduces data accessibility and the efficiency of networks. In this paper, we propose noble method, Friendship-VaR that excludes selfish nodes from a group of VANET. Friendship-VaR enables to improve data accessibility by eliminating selfish nodes and sharing data among reliable nodes. Friendship-VaR determines selfishness of nodes by simple data exchange. The experiments shows proposed method outperform existing method in terms of data accessibility.

  • Object Tracking is a technique for tracking moving objects over time in a video image. Using object tracking technique, many research are conducted such a detecting dangerous situation and recognizing the movement of nearby objects in a smart car. However, it still remains a challenging task such as occlusion, deformation, background clutter, illumination variation, etc. In this paper, we propose a novel deep visual object tracking method that can be operated in robust to many challenging task. For the robust visual object tracking, we proposed a Convolutional Neural Network(CNN) which shares weight of the convolutional layers. Input of the CNN is a three; first frame object image, object image in a previous frame, and current search frame containing the object movement. Also we propose a method to consider the motion of the object when determining the current search area to search for the location of the object. Extensive experimental results on a authorized resource database showed that the proposed method outperformed than the conventional methods.

  • Recently, rainwater has come to the forefront as an alternative resource contributing to solving various environmental problems, especially those related to water. However, more or less biased perspectives on rainwater as a pollutant, mainly derived from acid rain, have still been pervasive in public as well as research communities. Considering the significance of rain harvesting in recent society, it is necessary to promote educational efforts to overcome such social prejudices and improve desired values towards rainwater. Thus, this research attempted to develop a teaching-learning program focusing on the theme of rainwater for high school students in Korea. To verify the effectiveness of the program, one group pre/post testing was conducted with 57 students participating in the courses. According to the survey, students show significant differences in both awareness and attitude towards rainwater as well as water after the courses. In conclusion, this study has an implication on developing an effective educational way to improve students' positive recognitions and attitudes regarding rainwater-related issues. Such an educational effort might contribute to sharing the worthiness of preserving rainwater with the future generation and promoting rainwater harvesting within wider public participation.

  • Crucial aspects to successfully realizing the re-emergence of a contemporary and sustainable supercomputing community in South Korea will involve the devoted efforts and support from key government and R&D organizations. We suggest various supplementation plans regarding the roles of support for the statutory plan. This includes the committee and the plans which are often missing necessary support systems that help competent ministries to plan properly according to the missions of the research center. This dissertation suggests that adjustment in the HPC trends will depend upon exposing and correcting problems in the law as well as overall improvement of the law. Also, the total development of a super computing market is necessary. The results of these guidelines will create a spread of demand for supercomputing for national IT resource sharing, and will foster the development of supercomputer specialists worldwide. Other major end results include significant increases in research productivity and increased rates of product development.
