The purpose of this study was to examine the acoustic perception different by formants change for profoundly hearing impaired children with cochlear implants. The subjects were 10 children after 15 months of experience with the implant and mean of their chronological age was 8.4 years and Standard deviation was 2.9 years. The ability of auditory perception was assessed using acoustic-synthetic vowels. The acoustic-synthetic vowel was combined with F1, F2, and F3 into a vowel and produced 42 synthetic sound, using Speech GUI(Graphic User Interface) program. The data was deal with clustering analysis and on-line analytical processing for perception ability of acoustic synthetic vowel. The results showed that auditory perception scores of acoustic-synthetic vowels for cochlear implanted children were increased in F2 synthetic vowels compaire to those of F1. And it was found that they perceived the differences of vowels in terms of distance rates between F1 and F2 in specific vowel.

This paper describes the development of integrated simulator with GUI(Graphic User Interface) for traction power supply system. This simulator consists of a lot of calculation modules such as TPS, train time schedule, line constant, and power supply system analysis. Each module has input and output structure respectively. The algorithms of all modules have confirmed the validity to comparison with field test that is performed on both high speed railway line and conventional line.

In this study, a new method of dental plaque scoring is proposed by adopting new criteria to divide the tooth surface with utilizing the geometrical features of a tooth color image. For the possible clinical usage of our new plaque scoring system, GUI(Graphic User Interface) system is also implemented to estimate the numerical plaque index for a specific tooth by designing the supplementary database management module that handles dental plaque scores.

Recently, the system of the industry demands quick and accurate measurement for the mass production and high quality. Also, we need to improve the accuracy to decrease the failure rate in automatic assembly processing and improve the confidence, durability and the compatibility of parts. To answer this tendency and requirement, we have developed many accrate measuring instruments and methods. In this paper, we develop the whidows program using the DSP board(TMS320C25) which is used the data acquisition and the Visual C $^{++}$ , a windows programming language. We perform the measurement, analysis and output process in GUI(Graphic User Interface)environment. By using system, we will save the time required for the hand-worked measurement and avoid the useless iterative measurement. Furthermore, we expect to improve the productivity through automotive quality control in manufacturing process.s.

In this study, we present an efficient ambulatory speech audiometric system to detect one's hearing problems at an earlier stage as possible without his or her visit to the audiometric testing facility such in a hospital or a clinic. To estimate a person's hearing threshold level in terms of speech sound response in his or her local environment, a digital assistant(PDA) device is used to generate the speech sound with implementing audiometric Graphic User Interface(GUI) system. Furthermore, a supra-aural earphone is used to measure a subject's hearing threshold level in terms of speech sound by the compensating the transducer's gain by adopting speech sound calibration system.

Marine Structures are very costly and need a continuous inspection and maintenance routine. The most effective way to control the structural health is the application of an expert system that can evaluate the importance of any distress on the structure and provide a maintenance program. An extensive literature review, interviews with expert supervisors and a national survey are used to build a decision support system for concrete structures in sea environment. Decision trees are the main rules in this system. The system input is inspection information and the system output is the main cause(s) of distress(es) and the best repair method(s). Economic condition, severity of distress, distress situation, and new technologies and the most repeated classical methods are considered to choose the best repair method. A case study demonstrates the application of the developed decision support system for a type of marine structure.

현재 Android 에서는 대부분 Java 언어로 응용 프로그램을 개발한다. 그러나 C 언어로 응용 프로그램을 개발해야 하는 경우도 많다. Android 에서 C 언어로 응용 프로그램을 개발하기 위해서는 NDK(Native Development Kit) 를 설치해서 사용해야 한다. Android 시스템에서 Linux 커널은 Android Runtime Java 프로세스만을 부팅한다. 그러나 만약 Android 에서 C 프로세스를 부팅한다면 C 언어로 직접 응용 프로그램을 개발할 수 있다. 본 논문은 Android 시스템에서 Android C 프로세스를 부팅시키는 간단한 방법을 제시한다. 그리고 적합한 C/C++ GUI(Graphic User Interface) 라이브러리와 응용 라이브러리를 확보하거나 또는 개발하여 설치한다면, 현재의 Java Android 를 C Android 로 변환시키게 된다.

This paper proposes an algorithm of CAD data extraction for the computer controlled marking system. In general, logo has been directly designed at the marking controller, but that is not an effective method because of the very limited working area. In this paper, for the data extraction we used a general PC and Auto CAD for logo design, and developed the software with GUI(Graphic User Interface) method. Then the data is transferred to the marking controller for marking on the object. With experimental result we showed the proposed algorithm to be very effective in the computer controlled marking system.

This paper describes a new algorithm for irregular shapes allocation (known as nesting) and cutting path optimization, both implemented in PC-based software with graphic user interface (GUI). Main characteristic of the nesting W is that it deals with only vertices of Placed Pieces to reduce calculation time and for effective allocation. And the other characteristic of the nesting program is that every parts are grouped with respect to their areas and placed along the column of placement region. The cutting paths can be determined by an optimization method called simulated annealing. It was shown that the developed code is superior to other previous nesting H in elapsed time and waste ratio.
