A Study on DPA Countermeasures of the block-type ciphers
Journal of the Korea Industrial Information Systems Research, volume 7, issue 4, 2002, Pages 1~8
Attacks have been proposed that use side information as timing measurements, power consumption, electromagnetic emissions and faulty hardware. Elimination side-channel information of prevention it from being used to attack a secure system is an active ares of research. In this paper, differential power analysis techniques used to attack DES are compared and analyzed finally, we propose a software prevention idea of DPA attack for DES-like ciphers.
Content based Image Retrieval System by Shape Global Feature and Histogram
Journal of the Korea Industrial Information Systems Research, volume 7, issue 4, 2002, Pages 9~16
Content based Image retrieval methods in the multimedia information retrievals use primary visual features such as color, texture and shape. Color and texture generally are used as features of the image retrieval systems. But these systems may produce errors in similar image retrieval because two images with different shapes can represent very different contents. Therefore, the use of shape describing features is essential in an efficient content based image retrieval system. In this paper, after the global features filtering process by the boundary of objects, we have created a better shape similarity image retrieval system by a histogram of shape information.
High Speed Wavelet Algorithm for Computation Reduction of Adaptive Signal Processing
Journal of the Korea Industrial Information Systems Research, volume 7, issue 4, 2002, Pages 17~21
Least mean square(LMS) algorithm one of the most popular algorithm in adaptive signal processing because of the simplicity and the small computation. But the convergence speed of time domain adaptive algorithm is slow when the spread width of eigen values is wide. Moreover we have to choose the step size well for convergency. in this paper, ie use adaptive algorithm of wavelet transform. And we propose a new wavelet based adaptive algorithm of wavelet transform. And we propose a high speed wavelet based adaptive algorithm with variable step size, which is linear to absolute value of error signal. We applied this algorithm to adaptive noise canceler. Simulation results are presented to compare the performance of the proposed algorithm with the usual algorithms.
Effects of Chaotic Signal in the Cyclic Connection Neural Networks
Journal of the Korea Industrial Information Systems Research, volume 7, issue 4, 2002, Pages 22~28
It has been reported that neural network with cyclic connections generates limit cycles. The dynamics of discrete time network with cyclic connections has been analyzed. But the dynamics of cyclic network in continuous time has not been known well due to its huge calculation complexity. In this paper, we study the dynamics of the continuous time network with cyclic connections and the effect of chaotic signal in the network for transitions between limit cycles.
Precision Measurement using Scan-line image Segmentation Method
Journal of the Korea Industrial Information Systems Research, volume 7, issue 4, 2002, Pages 29~36
In this paper, a new edge detection method for area images is presented based on the scan-line image segmentation technology. The existing algorithms are lack of precision in its detections due to the noise factors such as depth perception and illumination problems when processing the 3D image into a 2D image. The general process of applying the scan-line method is to extract straight line components to determine the shape of the objects. However, we implement this method to an arc curve for precise detections. the paper proved precise detections that from off line to on line.
The system design for contents measurement of density and moisture in compaction
Journal of the Korea Industrial Information Systems Research, volume 7, issue 4, 2002, Pages 37~45
In this study, to measure the density and moisture of compaction, it is designed to use the 2 neutron and 5 gamma-ray detectors. Also, it can be know that Co-60 gamma-ray and Cf-252 neutron source are more useful for this system, because discharge of radiation are better than other sources. They are more profitable to improve their accuracy. Especially, to remove the interference of their reciprocal action between neutron and gamma-ray detectors it is designed shield materials with lead between 2 neutron and 5 gamma-ray detectors each other. It is performed the optimal design to shield under the suggested values completely. Because this system will use portable, so decrease of their weight are so important. For this reason, it can be decrease their weight of 5.2[kg] with shield material between each detectors and it can be think mote easy to carry and use on the industrial Spot.
An Analysis of Human Reliability by Industrial Accident Statistics Data
Journal of the Korea Industrial Information Systems Research, volume 7, issue 4, 2002, Pages 46~52
Due to the administrative expand and the paradigm shift in global environments, the range for the enterprises assessment are now expanding to inclusive administration assessment including all kinds of accidents in work places as well as products and services. Therefore continuous investment and concern to safety and health are needed since some faults in safety and health lead to the enormous expense as well as decline of brand image. In this paper, n are concerned with the safety administration in industrial field and analyze the accident data, before and after the establishment of specialized organization for accident prevention, using the reliability growth model of Duane. The validity of the model is verified under the assumptions of NHPP(non-homegeneous Poisson process) of the accidents.

Journal of the Korea Industrial Information Systems Research, volume 7, issue 4, 2002, Pages 53~58
This paper presents a adjustment synthetic control chart that is an integration of the Shewhart X chart and the conforming run length(CRL) chart. The application of the adjustment synthetic control chart my therefore substantially enhance the effectiveness process control for manufacturing. In the synthetic control chart, denotes the average number of the X sample required to detect a process shift. The synthetic control chart outperforms the EWM chart and the X chart when σ is greater than 0.75σ. And the X-CRL charts suggested above evaluate using the conditional probability.
Security Method for Approval Process of Payment System
Journal of the Korea Industrial Information Systems Research, volume 7, issue 4, 2002, Pages 59~65
Payment systems in EC need confidentiality, integrity, non-repudiation. All transactions between cardholders and merchants must be authorized by a payment gateway in SET protocol. RSA secret key operation which requires heavy computation takes the most part of the time for payment authorization. For the reason, a heavy traffic of payment authorization requests from merchants causes the payment gateway to execute excessive RSA secret key operations, which may cause the bottleneck of the whole system. To resolve this problem, One-Time Password technique is applied to payment authorization step of the SET protocol.
Design of an Adaptive Fuzzy Sliding Mode Position Controller
Journal of the Korea Industrial Information Systems Research, volume 7, issue 4, 2002, Pages 66~73
Although the general sliding mode control has the robust property, bounds on the disturbances and parameter variations are known to the designer of the system control. But sometimes these bounds may not be easily obtained. However, fuzzy control provides an effective way to design the controller of the system with the disturbances and parameter variations. Therefore, combination of the best feature of fuzzy control and sliding mode control is considered. When using the conventional VSC, generally the reaching phase problem occurs, which cause the system response to be sensitive to parameter variations and external disturbances. In order to overcome these problems, an adaptive fuzzy VSC with sliding surface eliminating reaching phase is proposed. The validity of the proposed scheme is shown by results of experiments for the BLDC motor.

Journal of the Korea Industrial Information Systems Research, volume 7, issue 4, 2002, Pages 83~89
Oil ring and sound proof rubbers are very much important because the cause of oil leakage are mostly occupied by these rubbers. So good oil rings are the necessary parts of autolife expansion. The expensive selection system keeps from factory automation and most works are established manually. These study has been the basis of test equipments automatically in rubber products and DCT algorithm has been applied and the selection system is made efficiently differentiating good or poor.
A Study on the Design of Monitoring Architecture for the Grid NOC
Journal of the Korea Industrial Information Systems Research, volume 7, issue 4, 2002, Pages 90~99
Grid makes it possible to cooperate with other network area by sharing and using distributed resources. In order to manage effectively large-scale Grid network resources, Grid NOC needs monitoring architecture that can manage distributed resources in one time. Being restricted within specific managing area conventional network management system has limitation in extension of managing area and in general management of heterogeneous resource. In this paper, we design a monitoring architecture that can take in the situation and has scalability. In the monitoring architecture the network areas publish information in a common directory service, and then Grid NOC can connect to the network areas directly by using this information. Therefore, it makes us possible to manage overall large-scale resource of Grid network reducing load.
A Study of Successful Implementation of Application Service Providing Based on the Perception of Small and Medium Corporations in Korea
Journal of the Korea Industrial Information Systems Research, volume 7, issue 4, 2002, Pages 100~105
This study evaluates the application sum providing(ASP) approach based on the perceptions of Koreas small and medium corporations, especially in the manufacturing industry. As considering the costs and risks of system implementation and maintenance, ASP would be a favorable alternative. Based on the survey of 25 cases, we found that as long as the level of perception on ASP is concerned, 80 percent of firms responded no or a little idea about the ASP service. Moreover the acceptance possibility of ASP service in the near future was less than 10 patent, and the primary reasons were found as follows: (1) lack of confidence regarding on the effect, (2) apprehension of data security, (3) issue of handling the existing employees, and (4) possibility of fee structure change after the implementation and stabilization. The guidelines to increase the recognition and successful implementation of ASP service in Korea are proposed.
