This study is a small-scale replication study of Kubota (1998). Kubota discovered that L1 rhetoric was not the main cause of L2 writing problems. The conclusion of Kubota's study was in contrast to that of contrastive rhetoric research that claimed that the use of L1 rhetorical styles in L2 writing negatively affects the quality of L2 writing, in particular, at the organizational level. According to Kubota(1998), the use of Japanese rhetorical styles did not deteriorate the quality of English writing. By investigating Korean ESL learners, this replication study examined whether L1 and L2 writings have the same rhetorical styles and how L1 rhetorical styles affect the L2 writing quality. The study analyzed Korean and English persuasive writings written by 12 Korean ESL learners in terms of organization. The results show that Korean learners of English used different rhetorical styles in their L1 Korean writing and L2 English writing. However, there was a positive relationship between L1 Korean and L2 English organization scores.

This paper presents an output arbitrator for input buffering ATM (Asynchronous Transfer Mode) switches using neural networks. To avoid blocking in ATM switches with blocking characteristics, it is required to buffer ATM cells in input buffer and to schedule them. The N$\times$N request matrix is divided into N/16 submatrices in order to get rid of internal blocking systematically in scheduling phase. The submatrices are grouped into N/4 groups, and the cells in each group are switched alternatively. As the window size of input buffer is increases, the number of input cells switched in a time slot approaches to N. The selection of nonblocking cells to be switched is done by neural network modules. N/4 neural network modules are operated simultaneously. Fast selection can be achieved by massive parallelism of neural networks. The neural networks have 4N neurons and 14N connection. The proposed method is implemented in C language, and the simulation result confirms the feasibility of this method.

It is being continued that studies is to supply users with various web service easily and simply. XML, extensible mark up language for web has been developed, and WSDL is provided for web service to UDDI registry in order to more efficient usage. SOAP protocol can be used for firewall endpoint because it uses HTTP as transfer mechanism. In this paper, we are studied dealing with installing agent in marketplace and communicating among service supplier and UDDI. Then agent through SOAP to provide exact and prompt service to demands of users.

This paper describes prototype Virtual Reality Ship Simulator (VRSS) that we have recently developed next-generation training equipment based on the virtual reality (VR) technology. The inherent defects of conventional ship simulators are enormous costs and difficult system upgrade due to the system construction, such as large mock-up bridge system, wide visual presentations, In this paper, to cope with those problems, we explored VR technology that can give realistic environments in a virtual world. Then we constructed prototype VRSS system, which is, consists of PC-based human sensors, and Databases set having 3D object models and coefficients of Head Related Transfer Functions (HRTFs). 3D-WEBMASTER authoring tool was used as Virtual Reality Modeling Language (VRML). Using the VRSS system, we constructed Port an Passage Simulator for the harbor of INCHON in Korea, and Ship and Sea State Simulator for an arbitrary given sea environmental states by user. Through many simulation tests, we testified the efficiency of developed prototype VRSS by subject assessment with five participants. Then, we present results on the simulation experiments and conclude with discussion of evaluation results.

This paper describes the design of Korean electronic Mail system which is installed at DECnet in Seoul National University computer center. In our system we introduce facilities for command processing and naming service in Korean, which was impossible in most mail systems. We emphasize flexibility in the design of Message Transfer Agent, for there are numer-ous code representions for Korean language.

The macro-parametric approach, which is a method of CAD model exchange, has recently been proposed. CAD models can be exchanged in the form of a macro file, which is a sequence of modeling commands. As an event-driven commands set, the standard macro file can transfer design intents such as parameters, features and constraints. Moreover it is suitable for the network environment because the standard macro commands are open, explicit, and the data size is small. This paper introduces the concept of the macro-parametric method and proposes its representation using XML technology. Representing the macro-parametric data using XML allows managing vast amount of dynamic contents, Web-enabled distributed applications, and inherent characteristic of structure and validation.

Protocol specifications and service definitions for distributed open system applications are defined using ASN.1. Therefore, to implement an open system application likes MHS, it is necessary to have well defined encoding/decoding modules which translate ASN.1 protocol specifications into their transfer syntaxes. However, that work is usually tedius, time consuming, and error prone. In this paper, we designed and implemented a new ASN.1 tool set which includes a new ASN.1 run-time library, called HY BER/DER, and an enhanced ASN.1-to-C compiler, called HYASNC$^{+}$. HYASNC$^{+}$ automatically generates C language encoder/decoder stub files and heder files for basic ASN.1 types and subtypes defiend in X.208 recommandation, and all X400 MHS system macro definitions. And, we evaluated the performance of HYASNC$^{+}$ compiler and HY BER/DER run-tiem library, and tested the interoperability of ASN.1 run-time library.

This paper presents a technique of imposing the prosodic features of a native speaker's utterance onto the same sentence uttered by a non-native speaker. Three acoustic aspects of the prosodic features were considered: the fundamental frequency (F0) contour, segmental durations, and the intensity contour. The fundamental frequency contour and the segmental durations of the native speaker's utterance were imposed on the non-native speaker's utterance by using the PSOLA (pitch-synchronous overlap and add) algorithm [1] implemented in Praat[2]. The intensity contour transfer was also done in Praat. The technique of transferring one or more of these prosodic features was elaborated and its implications in the area of language education were discussed.

The study aims at looking, into conceptual transfer of environment between Minimal Art and Minimalism architecture and analysing architectural expressional characteristics which could visually show pro-environmental expression from concept of environment-orientation in the architecture in regional minimalism. This study issued the survey of Minimalism architecture as newly architectural trend since Late-Modernism, and pro-environment as important paradigm in the near future. In this analyses, the characteristics of pro-environmental expression can be classified as follow ; a the brightness and darkness of light, b. the perspective view of simplified wall, c. the visualization of environmental characteristics, d. the transparency and reflectiveness of glass, e. the all direction of cube, f. the visual division of architecture. These show that symbolized variety implying expression variety and implying Oriental view of nature were expressed as unique language of regional Minimalism architecture, by visual simplicity as characteristics of Minimalism and Occidental Modernism as motive of Minimalism.

This paper describes BSDL(Behavioral/Structural Description Language), CDTF(Control Data Text File) and state synthesizer built for use in ICSC(InCheon Silicon Compiler). BSDL describes structral and behaviral specifications of an ASIC(Application Specific IC) for digital system design. ICSC's paser generates CDTF consists of if-then-else, arithmetic and data transfer statement according to each BSDL statement. State synthesizer generates CCG(Control Constraint Graph) in consideration of execution of statement and generates VCG (Variable Constraint Graph) in consideration use of variable generation and use of variable. Also, it involves allocating algorithm operation nodes in the data path and the control path to machine states with minimum state number and as small area as possible.
