One method to improve quality before releasing of S/W after development is to enhance the reliability, whose direct methodology is to detect and revise fault through testing. Once the S/W is released because it meets the target reliability, the operational reliability problem arises. It is obvious the operational reliability different from that of testing stage depending on the condition whether it is universal(package) S/W or dedicated S/W. I propose the methodology to calculate operational software reliability of universal and dedicated S/W in this paper.

The amount of audio-visual records production is growing rapidly and its formats are various. However, the audio-visual records are hardly managed and transferred. There are four different problems for checking how to transfer and manage audio-visual records of the central government: production and register, management and utilization, transfer, and dedicated program management. For solving these problems, the study proposes the development of process tools for audio-visual records, such as dedicated processes and S/W; the standardization of audio-visual records' management; the changes of audio-visual records officer's recognition; the need to educate dedicated audio-visual records managers; the recruitment of professionals dedicated to audio-visual records in the National Archives of Korea. Additionally, it is necessary to make an effort into practical use and preservation of audio-visual records.

Dedicated Short Range Communications(DSRC) is a block of spectrum in the 5.8GHz band. DSRC is the useful technology of ITS Service. Japan operates ETCS, VICS by DSRC technology and DSRC technology is used ETCS Standard in Korea. There are many kind of utilization of DSRC in ITS. This is a study for traffic information service and collection with DSRC. Traffic management server service traffic information to driving vehicle by RSE(Road Side Equipment). OBU(Onboard Unit) in vehicle send the information to PDA(Personal Digital Assistant). Client S/W show the information to driver by text, pictogram, sound and return PDA H/W ID to OBU. Server make section traffic information by the PDA H/W ID information.

For developing new algorithms or dedicated hardware by using general purpose Digital Signal Processor chip, emulator H/W and simulator S/W are indispensible. But the most of DSP emulators have limitations on H/W flexibility according to their generalized architectures. In this paper, a DSP evaluation system for real time signal processing was developed using TMS 32020. The I/O buffers storing acquisition data of the system were designed to have variable length $(1\sim2048samp1es) &$ sampling frequency $l00\sim8KHz$.

Purpose: A mother's working environment is believed to be a major determinant of exclusive breastfeeding (EBF) practice. We aimed to define the influence of a facility dedicated to breastfeeding and a breastfeeding support program at the workplace on breastfeeding practice. Methods: A cross-sectional study was performed in five workplaces. The inclusion criteria were female workers whose last child was between 6 and 36 months old. Observational data were obtained and a questionnaire was filled out. The World Health Organization definition for EBF was used. Results: Data from 186 subjects (74 office workers and 112 factory workers) were collected. Just over half (52%) of the mothers were between 20 and 46 years old, 75.3% had graduated from high school and university, 12.9% had more than two children and 36.0% owned a house. The prevalence of EBF during the last 6 months was 32.3%. A proper dedicated breastfeeding facility was available for 21.5% of the mothers, but only 7.5% had been in contact with a breastfeeding support program. The presence of a dedicated breastfeeding facility increased EBF practice almost threefold, by an odds ratio (OR) of 2.74 and a 95% confidence interval (CI) of 1.34-5.64 (p<0.05). Knowledge of the breastfeeding support program increased EBF practice by almost six times (OR, 5.93; 95% CI, 1.78-19.79) (p<0.05). Conclusion: Our findings suggest that Governments should make it obligatory for employers to offer a breastfeeding support program and a dedicated breastfeeding facility at the workplace as these simple measures significantly increase EBF.

To meet the requirements of high performance and reliability as a industrial motor drive, we developed an integrated oil-line fault diagnosis and monitoring system which consists of DSP-based controller and PC-based MMI (Man-machine interface) program. The dedicated controller performs real-lime fault detections and protections. The MMI program monitors the on-line fault status of the drive system and offers full explanations of the fault name(WHAT?), deducible causes of the fault operation(WHY?), and chock points (HOW?) based upon the experiences of the expert. Also the TRACE data which was stored just before and after the accident can be scrutinized using MMI tools.

In this paper, a control and data analysis S/W of a dedicated measuring machine for cams is developed. A rotary encoder is employed to measure the angular displacement of the motor, and a linear scale does the linear displacement of the prove. The design and measuring data are interpolated by cubic spline curves respectively to compute the error which is defined by the maximum distance between two curves. Further, optimization module to find the exact error is also developed to remove the error occurred due initial measuring position. The developed system takes only 6 minutes to measure the cam and to analyze the measuring data while the CMM takes about 1 hours even with a skilled operator.

In this paper, a body-worn type digital hearing aid (DHA) based on a dedicated DSP chip is developed. A fitting software running on a PC supported by the Win95 OS is also developed. The fitting protocol is based on the NAL-R procedure applied to eight frequency bands, but it is designed to support a curvilinear fitting to cope with the nonlinear perception of hearing-impaired listeners. Preliminary subjective tests regarding the speech intelligibility and perceived quality revealed that the new DHA could be of benefit to hearing aid users.
