  • This study attempted to develop a speech recognition module applied to a wheelchair for the physically handicapped. In the proposed speech recognition module, TMS320C32 was used as a main processor and Mel-Cepstrum 12 Order was applied to the pro-processor step to increase the recognition rate in a noisy environment. DTW (Dynamic Time Warping) was used and proven to be excellent output for the speaker-dependent recognition part. In order to utilize this algorithm more effectively, the reference data was compressed to 1/12 using vector quantization so as to decrease memory. In this paper, the necessary diverse technology (End-point detection, DMA processing, etc.) was managed so as to utilize the speech recognition system in real time

  • In order to utilize the information of well-known grinding data or grinding machine, a database needs to be designed by considering the delicate property of the machine tools for the high precision and quality of the demanding specification. Among the machine tools, machining conditions of the grinding are various and knowledge repeatance obtained form the grinding process are less credable.Therefore it is desirable for D/B, which is used to set the grinding conditions, to utilize the maximum machine tool capability. The present paper studied occurance limit of chatter vibration and burn considering the characteristics of machine tool. And also basic experiments were performed to establish optimum grinding canditions which can maximize the machining efficiency.

  • At container terminals, a major measurement of productivity can be work efficiency. For improving the productivity of container crane, the more efficient container yard operation method is necessary in container terminals. Recently, container terminal operators make an experiment on the dual cycle operation, which ship loading/unloading were carried out simultaneously, for increasing the productivity of container crane. In this paper, propose a system operating efficient dual cycle methods as utilize Ad-hoc technology in distributed port operation system. The dual cycle methods that proposed recognizes position information of Y/T during an action in Ad-hoc networks in case of container transfer works by real time as load an Ad-hoc module to Y/T taking charge of a container transfer with quay and yard. Utilize Ad-hoc networks technology in an operating system of container yard, and efficiently distributed processing done Y/T to container crane compare with operation systems of the existing dedicated method, and an improvement can do an operating system of an yard.

  • The aim of this paper is to clarify the structural compliance of the constrained flexible manipulator and to develop the force control algorithm by using the compliance of the links. The proposed structural compliance control consists of the position control to utilize a flexible manipulator model (considering the compensation for the elastic deflection of links) and the passive force control to utilize the rigid manipulator model (without considering the compensation for the elastic deflection of links). We present the experimental results for the case when applying the only position control, and when applying the structural compliance control. Finally, a comparison between these results is presented to show the performance of our method.

  • Dispute plays a key role in maintaining the desirable performance of trade transaction. In an effort to stay competitive in a global marketplace, the Korean companies need to become more aware of alternatives to costly and time-consuming litigation. Korean companies, therefore, should be more concerned with ADR(Alternative Dispute Resolution) system and should utilize ADR to settle their disputes effectively and efficiently. ADR encompasses all process of dispute resolution as a substitute for the traditional litigation. Generally, three kinds of ADR are available in Korea: Negotiation, mediation, and arbitration. This article investigates reasons why ADR isn't used well in Korea and suggests ways how ADR can work best in international trade disputes. To expand ADR system in international trade disputes, it is very important for both the company and the scholar to recognize the concept and usefulness of ADR system. The Korean Commercial Arbitration Board also must help both Korean companies and scholars recognize the mechanism of dispute resolution and utilize ADR system in international trade disputes.

  • A bacterium, which can utilize cyclohexanol as a sole source of carbon and energy, was isolated from sludge in sewage of Ulsan Industrial Complex for Petrochemicals, Korea and identified as Rhodococcus sp. TK6. The growth conditions of the bacteria were investigated in cyclohexanol containing media. The bacteria utilized cyclohexanol, cyclohexanone, cyclohexane-1,2=diol, cyclopentanol, cyclopentanone, and $\varepsilon$-caprolactone but not cyclohexane, cyclohexane-1,2-dione, and cyclooctanone. The bacteria were able to utilize alcohols such as ethanol, 1-propanol, 1-butanol, 1-pentanol, 1-hexanol, 2-methyl-1-propanol, 3-methyl-1-butanol, 2-propanol, and 2-butanol as well as cyclohexanol, organic acids such as adipate, propionate, butyrate, valerate, n-caproate, and 6-hydroxycaproate, and aromatic compounds such as phenol, salicylate, p-hydroxbenzoate, and benzoate as a sole source of carbon and energy. Cyclohexanone as a degradation product of cyclohexanol by Rhodococcus sp. TK6 was determined with gas chromatography.

  • Pseudomonas maltophilia N246 carrying on OCT plasmid grew on n-alkanes of 6 to 14 carbon atoms, but not on n-alkanes of more carbon atoms. P. maltophilia strains with and without OCT plasmid could utilize primary alcohols. aldehydes and fatty acids derived from n-alkane. The N246 strain could also utilize monocarboxylic and dicarboxylic acids, and terminal branched dimethyloctane. Unlike the genes of alcohol dehydrogenase and aldehyde dehydrogenase which were located on both the chromosome and the OCT plasmid, genes for the alkane hydroxylase components were located only on the OCT plasmid in P. maltophilia N246.

  • With the globalization trend in S&T activities, Korean research organizations have begun to utilize foreign researchers. The performance of foreign researchers is generally regarded satisfactory, but there are many problems too. Moreover, there has not been any research carried out even though there is a growing need for the management of foreign researchers. This paper identified the performance / motivation factors of foreign researchers in Korean research organizations. The statistical results show that the efforts and research capabilities are the most important variables for performance of foreign researchers in Korean research organization. In addition, it is found out that university shows higher performance than government research institute and corporate research organization while it pays the least to the foreign researchers. It is interesting to see that the level of monetary payment is not strongly related with the performance of foreign researchers. In order to utilize the full potential of foreign researchers, it is necessary to enhance the living infrastructure. In addition, due attention should be given to the managerial capabilities of R&D administrators and evaluation/incentive systems of foreign researchers in Korean research organizations.
