Viewed from the framework of world system, international migration is connected sometimes to unequal power relations by prejudice and discrimination in destination areas, or to equal power relations by intentional effort for harmonious multiculturalism. According to the existing ethnic relation theory, assimiationism, it is natural that ethnicity is fading away as the foreign immigrants of different ethnic background have long limed in a destination area, and thus the relative urban ethnic places are weakened and finally dissapeared. Through the various examples particularly on the United States, however, ethnicity would not be easily fading-away but be sustained for long time. Also, the characteristics of ethnicity or ethnic place are sometimes reivented or reconstructed as the various situation of multiculturalism is affected by postmodernism. Whether it is the thing made by ethnic segregation or by ethnic congregation, ethnicity and ethnic place are evidently a kind of affluent resources of culture and economy in the destination areas.

The aim of this article is to critically review the PRC's policies related to its minority nationalities with a special emphasis on the identification of minority nationalities(minzuzhibie) and the establishment of minority nationality autonomous regions(minzuzizhiquyu), as a part of national integration Process. In that Process, the intentional application of the criteria on nationality identification, the establishment of minority nationality autonomous regions, the population redistribution policies and the gerrymandering by the government played an important role in the deconstruction of traditional basis of identities and the territorialization of ethnicity. The goals of government have been the redefinition of 'Chinese', the the invention of 'Chinese nationality(zhongguominzu or zhonghuaminzu)'and the unification of its national territory. However, these have led to the unexpected result by creating the new ethnic-territorial identities along with the nationalities identified and the territories defined by the government.

In modern Asia major cities had same problem with lack of affordable housing for families. So they had to concentrate to the mass supply of housing and made some physical counter effects like high density of cities, limitation of parking space. Also people who lived in those cities could suffer from broken traditional community culture. To rebuild traditional community and increase land usage, Block housing is suggested as a new kind of multi-family housing for old town redevelopment. Now some governments are trying to make urban code to give some initiative for new block housing development in old city blocks. They expect this new housing type can help to solve serious problems like lack of parking area, green space and context of block. Also they hope that block housing development can help to increase safety of town and reduce cost of development. The purpose of this study is to review the establishment and development process of Block Housing and to confirm the aspect which has been changed with urban organization together. Also this study tried to find out the intentional characteristics of similarities and differences with comparison of Korea and Japan. And as a result we could find critical physical viewpoint, and provide considerations for future study and plan. Several cases of block housing in Korea and Japan were reviewed for comparative study and Post Occupancy Evaluation (POE) survey was examined to find satisfaction factors and problems which were expected to improved.

The purposes of this study are to understand the doctors' attitude and satisfaction about the review system of national health insurance claim in Korea and to suggest the way to improve this system This study conducted a survey of the doctors registered in the medical association in Seoul city. The survey was performed as a form of self-administered questionnaire from January 2004 to February 2004. The contents of questionnaire dealt with doctors' attitude and satisfaction about the review system of medical service claim. Totally, 1,037 members replied to our survey and we analysed 981 doctors' data, excluding incomplete responses. As a result, 89.7% of repliers showed a negative attitude about the influences of the review system on improvement of medical service quality, 98.0% of repliers have had experiences that they have given distorted insufficient medical services in order to evade the curtailment of service claim. Also, 91.6% of repliers stated that they have had experiences of intentional modification or alteration of diagnostic code to shun the curtailment. Most of the doctors showed negative attitude to the curtailment procedure and the review system of service claim originally intended to be one of the quality control methods of medical service in Korea also, the development of both scientific and reasonable parameters and criteria for claim is needed. 'Through the improvement of review system for appropriate medical service, there is a need of a way to increase the satisfaction of medical service providers, and to encourage the motivation for quality control. Also, education is strongly needed to provide doctors with sufficient information about review criteria and curtailment cases.

Because GPS signals are weak, system jamming is a real and present danger. This can happen when the receiver is subjected to intentional or unintentional interference by a transmitter. If the jamming signal is strong enough, the receiver can be operated to take corrective action automatically. Current methods to protect GPS receiver from jamming condition are based on spatial filtering. In this paper, the beamforming as referred to in signal processing technique used in arrays for directional signal reception was suggested and analyzed for anti-jamming. In order to change the directionality of the array when receiving a jamming signal, a beamformer can control the signal at each sensor. Therefore, cutoff angle ${\theta}$ was measured in the opposite direction of the jammer. GPS signals are only processed when the antenna element is within inside the cutoff angle. As a result, GPS positioning can be used in condition under cutoff angle $30^{\circ}$.

Modern electronic circuits are of importance for the function of communication, traffic systems and security systems. An intentional threat to these systems could be of big casualties and economic disasters. This study has examined susceptibility of electronic circuits inside the cavity by HPEM(High Power Electromagnetics). The UWB measurements were done at an anechoic chamber using a RADAN voltage source, which can generate a transient impulse of about 200 kV. The HPEM wave penetrated inside the metal case appeared to the long damped ringwave of pulse length compared with the incident wave. In addition, the resonant frequency generated inside the metal case occurred primarily in the range of 1~3 GHz. The frequency band of 1~3 GHz was influenced on the electronic circuit, which was confirmed by an external antenna and an internal absorber. The electronic circuit was influenced by HPEM infiltrated into the cavity at the 86 kV/m out of the metal cases. Also in case of an absorber the susceptibility of an electronic circuit was smallest among other cases(aperture, antenna). It is considered that absorber has a function absorbing electromagnetic wave infiltrated into the cavity and simultaneously limiting resonance by varying a boundary condition inside the cavity. Based on the results, electronic equipment systems could be applied to protection that has suited system requirements.

In this paper, we proposed a trellis coded Multi-Carrier CDMA 16 QAM system with multiple transmit/receive antenna diversity technique, which is simple and suitable for indoor wireless communications. The proposed multiple transmit/receive antenna diversity technique is that the transmitter sends a trellis coded Multi-Carrier CDMA 16 QAM signal from multiple transmitting antennas with intentional time delays, which makes a receiver possible to distinguish and combine the signals from different antennas. In wireless indoor communication system, if we allow the increase of the complexity of the system, it is also possible to achieve additional diversity gain in the performance with the combination of the proposed technique and the conventional receiving antenna diversity. Furthermore, we have found that the proposed trellis coded Multi-Carrier CDMA 16 QAM system, which employs multiple transmit/receive antenna, is less sensitive to the multiple user interference and fading than conventional receiving antenna diversity systems.

Old films or photographs usually have damages from physical or chemical effects, and the damage and digitalization make stain, scratch, scribbling, noise, and digital drop out in frames. Damages include global damage and local damage, and it is well known that local damage restoration is a main factor for improving image quality. Previous researches have focused on impairment localization (esp. for line scratch impairments) and restoration techniques for line scratch, dirt, blob, and intentional scratch. Inpainting is a key technique using partial derivatives to restore damages in images. It does not show good quality for the complex images because it is based on finite order for partial derivatives, and it takes much time complexity. In this paper, we present a modified inpainting scheme, where we use Sobel edge operator's and angle to compute isophotes, and compare our scheme with Bertalmio's scheme. We experiment our scheme with two old Korean films, and Simulation results show that our scheme requires smaller time complexity than Bertalmio's scheme with comparable reconstructed image quality.
