Intelligent Pattern Matching Based on Geometric Features for Machine Vision Inspection
Moon Soon-Hwan ; Kim Gyung-Bum ; Kim Tae-Hoon ;
The Journal of the Korea Contents Association, volume 6, issue 6, 2006, Pages 1~8
This paper presents an intelligent pattern matching method that can be used to acquire the reliable calibration data for automatic PCB pattern inspection. The inaccurate calibration data is often acquired by geometric pattern variations and selecting an inappropriate model manual. It makes low the confidence of inspection and also the inspection processing time has been delayed. In this paper, the geometric features of PCB patterns are utilized to calculate the accurate calibration data. An appropriate model is selected automatically based on the geometric features, and then the calibration data to be invariant to the geometric variations(translation, rotation, scaling) is calculated. The method can save the inspection time unnecessary by eliminating the need for manual model selection. As the result, it makes a fast, accurate and reliable inspection of PCB patterns.
Analysis of Performance and Availability of Mobile Cellular Systems

The Journal of the Korea Contents Association, volume 6, issue 6, 2006, Pages 9~15
To obtain realistic composite performance and availability measures, one should consider performance changes that are associated with failure recovery behavior. In this paper we address two modeling approaches, exact composite and approximate, and develop SRN models for these approaches. The former approach is to combine the performance and availability models and yields accurate results but generally faces largeness problem. To avoid the problem, the two level hierarchical model is developed. The upper level model describes the failure and repair behavior of the system and the lower level captures the pure performance aspect of the system, channel allocation and service. It models guard channel and preemptive handoff scheme. As numerical results, blocking and dropping probabilities are given for new call and handoff call, respectively.

Jung Kyung-Yong ;
The Journal of the Korea Contents Association, volume 6, issue 6, 2006, Pages 16~25
Most water tanks operating have been managed by people's five senses. A human material resource have been wasted awfully at this. In the present study, we suggest the wireless integrated system for managing water tank of reducing the wastage human resources and on-line real time managing efforts of water tanks. Water level sensor works the pump sending the data from water tank control to the wireless control on sensing water level. At this time, every kind data which happens in the water tank transmits the line transmission modem. Data to be received from the line transmission modem is stored at the database after we record the logs by each hour. We display the result to the web pages, after checking the pump motion, the pump error, the water level, the solar battery error, the chemicals, and the telephone line to the foundation data to be saved. Furthermore, this paper suggests empirical applications of the proposed wireless integrated system for managing water tank in order to verify its feasibility.

The Journal of the Korea Contents Association, volume 6, issue 6, 2006, Pages 26~32
Predictions on stock prices have been a hot issue in stock market as people get more interested in stock investments. Assuming that the stock price is moving by a trend in a specific pattern, we believe that a model can be derived from past data to describe the change of the price. The best model can help predict the future stock price. In this paper, our model derivation is based on automata over temporal data to which the model is explicable. We use Bayesian Information Criterion(BIC) to determine the best number of states of the model. We confirm the validity of Bayesian Information Criterion and apply it to building models over stock price indices. The model derived for predicting daily stock price are compared with real price. The comparisons show the predictions have been found to be successful over the data sets we chose.

The Journal of the Korea Contents Association, volume 6, issue 6, 2006, Pages 33~41
Nowadays, CCTV can be come across easily in public institutions, banks, and etc. These CCTV play very important roles for preventing many kinds of crimes and resolving those crime affairs. But in the case of recording image of a specific person far from the CCTV, the original image needs to be enlarged and recovered in order to identify the person more obviously. Interpolation is usually used for the enlargement and recovery of the image in this case. However, it has a certain limitation. As the magnification of enlargement is getting bigger, the quality of the original image can be worse. This paper uses FDP(Facial Definition Parameter) proposed by the MPEG-4 SNHC FBA group and introduces a new algorithm that uses face outline information of the original image based on the FDP, which makes it possible to recover better than the known methods until now.

Scramble and Descramble Scheme on Multiple Images
Kim Seung-Youl ; You Young-Gap ;
The Journal of the Korea Contents Association, volume 6, issue 6, 2006, Pages 50~55
This paper presents a scheme which scrambles and descrambles images from multiple video channels. A combined image frame is formed by concatenating the incoming frames from channels in a two dimensional array. This algorithm employs an encryption scheme on row and column numbers of the combined image frame and thereby yields an encrypted combined image. The proposed algorithm is to encrypt multiple images at a time since it recomposes images from multiple video channels yielding one by composite image, and encrypts the composite image resulting In higher security.
Key Recovery for IETF Internet Protocol Based on TTP
Rhee Yoon-Jung ;
The Journal of the Korea Contents Association, volume 6, issue 6, 2006, Pages 56~63
Key recovery has been the subject of a lot of discussion, of much controversy and of extensive research. Key recovery, however, might be needed at a corporate level, as a form of key management. The basic observation of the present paper is that cryptographic solutions that have been proposed so far completely ignore the communication context. IPSec is a security protocol suite that provides encryption and authentication services for IP messages at the network layer of the Internet. We propose example to provide key recovery capability by adding key recovery information to an IP datagram. It is possible to take advantage of the communication environment in order to design key recovery protocols that are better suited and more efficient.

This research was performed with the purpose to examine the Marquardt's learning organization theory and analyzed empirically the survey on 841 police officers in Korea. Altogether 841 questionnaires were collected from 23 police stations and one training institution. The sample group were composed of ranks and file sworn officers selected among the total police stations in Korea proper. The size of police stations, and its location has been taken into consideration in sampling procedure. We fan find out from this research that technology application, as subsystems of learning organization, directly related to learning dynamics significant effects on police learning organization. For building the learning organization in Korean Police, police manager should improve on the pointed technology application. Police officers could be given more scope for their problem-solving talents. Such developments would fit in well with the best policing model.
International Tax Avoidance Type and Tax Cooperation Between Nations
Kim Dong-Bok ;
The Journal of the Korea Contents Association, volume 6, issue 6, 2006, Pages 117~124
Thanks to globalization and multi-corporations which have further created complex economic systems over the years, we are now experiencing new aspects of economic challenges as well. Any country abiding by law and order is required to have taxpayer's consent and cooperation upon levying taxes, however, taxpayers will resist or try to avoid paying taxes at all if they can. Particularly, it becomes easier for them to do by using tax haven wherever they we, and their endeavor is not likely to stop as long as they can. These kinds of actions have undoubtedly created tax loopholes which have in fact surfaced and brought to attention to many. Inevitably, each country aggressively pursuits to exchange tax information with others and cooperate each other Thus this study will look into various types of international tax avoidance cases and its root causes and focuses on ways to cooperate amongst nations. The study also suggests possible ways to develop and enhance international tax systems for all the parties concerned.
