This study aims to examine the acoustic characteristics of Korean sibilant, especially aspiration in Korean fricatives (plain: /s/, fortis: /s'/) and affricates (aspirated: /$ts^h$/, lenis: /ts/, and fortis: /ts'/). Duration values (closure duration, frication duration, aspiration duration), center of gravity (COG) (of the total duration, of the two portions, in 10 ms), H1-H2 values (at the vowel onset) were examined in order to investigate the phonetic feature of aspiration in frication noise. This study further discusses how to define criteria for identifying aspiration in sibilant sounds by adopting 3 visual criteria for assessing aspiration. This visually-designated aspiration onset points are further matched with the COG decline points in 10 ms windows. The result shows that all the non-fortis sounds (/s/, /$ts^h$/, /ts/) contain aspiration, causing similar values of COG and H1-H2.

In this paper, we designed a system that can mine user's traversal patterns from web log files. The system cleans an input data, transactions of a web log file, and finds traversal patterns from the transactions, each of which consists of one user's access pages. The resulting traversal patterns are shown on a web browser, which can be used to analyze the patterns in visual form by a system manager or data miner. We have implemented the system in an IBM personal computer running on Windows 2000 in MS visual C++, and used the MS SQL Server 2000 to store the intermediate files and the traversal patterns which can be easily applied to a system for knowledge discovery in databases.

In this study, we developed a statistical software for measurement systems analysis. This software is patterned after the Measurement Systems Analysis Reference Manual developed by the Automotive Industry Action Group (AIAG). This software includes stability analysis, bias and linearity analysis, and gage R&R studies. This software was developed by using Delphi(version 4.0) and can be implemented on MS Windows 95 or higher level.

Linux cluster Server makes a high performance PC cluster system, and provides scalablity and availability as compared with an expensive single server. In this paper, we design and implement a VOD streaming service system to serve video and audio streaming services on the Linux cluster server. Our Streaming server supports the MS Window Media Format based on the RTSP streaming protocol.

This paper presents modeling of QIROV's motion on the X-Y plane. Modeling covered the dynamics of a ROV equiped with two trusters at tail, and it started with reconstructing the forces of X, Y and toque from two trusters' forces. The simulator built based on the modeling using Visual C under MS Windows XP.

The purpose of this study is to show the operations and implementations of ASP web database which uses open-source web site packages called bighitonline video shop. Some literature reviews have been done to reveal robust theoretical background for this research And also, some basic experiments as Preparatory Processes have also been made by using some softwares such as Windows XP professional, IIS, MS SQL Server and others. The main purpose of these experiments is to show strong theoretical and practical backgrounds. These experimental results in the micro-level showed to be successful to understand the Interrelations of web components and web-site architectures.

When you convert word processor files with large amounts of input data to PDF files in on/off line, current PDF conversion solutions do one of the source files to perform the conversion task in the Windows PDF virtual printer environment. Depending on the size of the original PDF file conversion speed to convert PDF to do a large amount of different and if you are performing a very slow speed. When you convert files to PDF in this sequence, depending on the capacity of the original file, PDF conversion rate is different, if automating a mass conversion to the PDF, the speed is very slow. In this paper, the PDF conversion which can use the Windows Terminal Server from one Windows Server when performing a PDF conversion processing of the source file, to create a multi-session Terminal, to perform the PDF conversion process at the same time was studied.

We propose ESS_WMCE. This paper explains the design and implementation of the EDSS running on ESS_WMCE. EDSS is a synchronization error control system for web based multimedia collaboration environment. We have an error detection approach by using hooking method. The technique of an error transmission is a mended model of utilizing an application sharing system. DOORAE is a good framework model for supporting development on application for computer supported cooperated works. It has primitive service functions. Service functions are implemented with an object oriented concept. It is a system that is suitable for detecting and sharing a software error rapidly occurring on web based multimedia collaboration environment by using software techniques. It is able to share an error as well as providing URL synchronization to access shared objects. When an error occurs, this system detects an error by using hooking methods in MS-Windows API(Application Program Interface) function. If an error is found, it is able to provide an error sharing to access shared objects.

This paper is to automate the intelligent and equipment to recycle the volatile organic compounds in various a gas stations and a laundry, in real life. In addition, based the ZigBee module and TCP/IP communications on ICT technologies, it's propose an integrated management system to monitor and manage an liquid at a remote location.Furthermore, it's propose a service model that can be freely managed from a remote location based on the app on android. In this paper, we present a communication protocol of the bridge modules and a liquefier of intelligent control system based ZigBee and MCU(Micro Controller Unit). Through the development of smart app based android mobile services in an integrated management system, it's represent for liquefier to a DB server for remote management(MS SQL 2012) and a web server (OS: Windows 2008).
