  • The paper deals with the implementation of prototype Risk Visualization Sytem (RVS). The RVS is one of the sub-system of Risk Management System (RMS) of National Maritime Police Agency in Korea. In this work, prototype RVS was constructed with virtual reality techniques. Using the prototype RVS, we carried out some performance tests for the various environmental conditions at sea. As results from tests, the prototype RVS can provide immersible virtual world. The results gave rise to the user interaction with 3D objects that give realistic reproduction of sear environments. Thus, we found that the prototype RVS should be a immersible visualization system of Risk Management System.

We define new hydraulic system and integrate modeling of Tire Roller through simulation of h\ulcornerdraulic system and design of controller. From above procedure. Hydraulic transmission system characteristics and target performance can be investigated. To follow the required performance, we select the parts of Tire Roller. We manufactured the prototype of Tire Roller, and will install the equipment for experiment.

  • Deck-plates are widely used on construction sites, and have the advantage of enabling contractors to achieve a relatively uniform quality. But nevertheless, quality deviation in deck-plate construction can occur as the result of differences in site conditions and the experience of crew workers. In this study, the authors present a site quality evaluation prototype for building deck-plate construction. Through analyses of case studies and interviews with experts, standard quality check sheets and a quality management index were developed by estimating the importance of quality check items based on a Failure Mode and Effects Analysis (FMEA) method. The applicability and effectiveness of the prototype was evaluated through a case study and interviews with case participants. It was found that the prototype promoted an active quality management as a way of continuously improving quality management in deck-plate construction instead of passive quality inspection practice.

  • Normal zone propagaton(NZP) properties were investigated on Bi-223/Ag tapes and prototype HTS cable. NZP experiments in tape were conducted in temperatures from 45K to 77K in zero field. Prototype HTS cable was molded using epoxy and the experiments were carried out under adiabatic condition in LN$_2$. NZP velocities in tapes with tow conditions of DC and AC currents were almost same at each temperature. NZP velocity in prototype HTS cable was 1.9-2.4 cm/sec in LN$_2$. Numerical analysis was carried out by a one-dimensional equation of heat balance. The simulation results of NZP velocity in Bi-2223/Ag tapes were similar to the experimental results.

  • Researchers who use science and technology information were found to ask an information service in which they can excerpt the contents they needed, rather than using the information at article level. In this study, we micronized the contents of scholarly articles into text, image, and table and then constructed a micro-content DB to design a new information system prototype based on this micro-content. After designing the prototype, we performed usability test for this prototype so as to confirm the usefulness of the system prototype. We expect that the outcome of this study will fulfill the segmented and diversified information need of researchers.

  • A train is subject to a series of reliability-related tasks through its entire life cycle. Among them the reliability demonstration is required for commercial trains and the test is performed during the commissioning period or the early stage of the commercial operation. On the other hands various test are carried out for prototype trains and hence their operational condition is quit different from that of the commercial trains. One should take account of these differences when reliability assessment is needed for the prototype trains. This paper presents a procedure and an analysis method to evaluate reliability of a prototype train. Reliability data have been obtained through test runs of the HSR-350x and operational conditions for the KTX and HSR-350x have been analyzed to compare the reliability targets of the prototype train.

  • LPM(Linear pulse motor) was developed as a prototype. In this paper, the design results of prototype and its dynamic characteristics are shown. The prototype was designed by using permeance analysis and the thrust value was also confirmed by comparing with the analysis results of the finite element method. To verify the performance of LPM. dynamic characteristics were measured. In slewing characteristic of the LPM, the thrust value of prototype LPM is higher than commercial level. A X-Y table was structured as a application of the prototype LPM. A controller and user's interface was also developed. By using this control system, the position error of X-Y table was checked. The repeat position error in linear movement was under than ${\pm}$ 100 micron.

  • A prototype selection method chooses a small set of training points from a whole set of class data. As the data size increases, the selected prototypes play a significant role in covering class regions and learning a discriminate rule. This paper discusses the methods for selecting prototypes in a classification framework. We formulate a prototype selection problem into a set covering optimization problem in which the sets are composed with distance metric and predefined classes. The formulation of our problem makes us draw attention only to prototypes per class, not considering the other class points. A training point becomes a prototype by checking the number of neighbors and whether it is preselected. In this setting, we propose a greedy algorithm which chooses the most relevant points for preserving the class dominant regions. The proposed method is simple to implement, does not have parameters to adapt, and achieves better or comparable results on both artificial and real-world problems.

  • Work is a bibliographic entity serving a key role for the collocation function of catalog. This study analyzed the concept of work, provided a new device to complement conventional FRBR work. The 'prototype' was suggested to enhance the collocation function of catalog, the highest level in FRBR. This study explained the definition, attributes of prototype, and relationships between prototype and work within FRBR model.
