Joint transform correlator (JTC) has been the most suitable technique for real time pattern recognition. This paper proposes a new phase adjustment which adopts two steps of random phase adjustment in the spatial domain and additional phase adjustment in the Fourier domain. Simulated results are presented to show the optimum condition of the phase adjustment and the effect on the correlation peaks, the peak signal-to-noise ratio and the level of discrimination.

This paper discusses about the beam pattern distortion caused by the failures of some antenna modules in the active array antenna and analyses the possibility of improvement through applying the beam pattern compensation method previously studied. The beam pattern distortion which is mostly represented as an increase of the sidelobe level, can be suppressed through re-synthesizing each module's magnitude and phase. This method was applied to the prototype of active array antenna system, and the results of antenna pattern distortion and compensation were analyzed and measured in the Near Field Chamber. Array failures are generally divided into random TR module failures and TRU(TR Unit: combination of TR modules, Beam Computation module, Power supply module) failures. The results of beam pattern compensation were analyzed in each failure and compared to the results of the simulation. The beam pattern compensation results applied to the real active antenna array system showed the similar to the simulation results. Consequently, it was verified the beam pattern could be compensated with the magnitude and phase adjustment of other normal antenna modules.

The research on the actual condition of the oriental health related industry has been made with defining it's phase. As a result, I have come to develope korean-type health model, which can solve the problems derived from the past herb medicine industry. The prospects and roles of the oriental health related industries are as follows: The phase adjustment of the oriental health related industry. The problems of modern medical science happens in the beginning of 21st century, the importance of oriental health improvement in the field of health business is now being on the rise. therefore it is necessary to readjust the present status of the oriental medicine and to take it into health area. Should the responsible institutes regarded on oriental medicine make clear prescription in terms of oriental health industry's role and limitation, they could contribute health circumstance in the 21st century. This is because oriental health related industry can be utiliged in not only protective area and curable area. The present situation of the oriental health related industry. These herb medical societies are flooded with various oriental health industry apart from the legal systematic control so far health industry apart from the legal systematic control so far. The expected survey can not be complete but random under these situations. Nevertheless oriental medical health industry area such as a diet cure, exercise treatment and living condition cure are being considerably expanded, especially living facilities improvement and mind control areas are toward worldwide. Consquently herb health industries are now？ consistantly developed by the influence of western nature treatment stemmed from the oriental medicine theory. The role and prospect of the oriental health related industry in 21st century. The oriental health industries can be helpful for the human being's health improvement in general but by the lack of scholastic oriental health theory, it does not contribute to the health welfare. If these problems are made up for in the field of theory area, the oriental health related industry will surely have the potentiallity and know how for health welfare. The successive role of these industry is depended on the fact that the characteristics of the oriental medicine should adjust to the real society with the systematic management. In the 21C, oriental health industry will certainly be vitalized owing to the social and periodical request especially in the area of oriental medical industry, oriental health drink industry, oriental health mind exercise industry, oriental health leasure industry and oriental health complex management industry. Among these areas, it is the oriental health complex amagement industry that will be the limestone of prosperity of the oriental health industry in 21C. Proposal for the social contribution of the oriental health related industry in the 21C. To achive the ultimate role of the oriental health industry in the 21c, first we should know how to use the oriental medicine. Second We should make an effort to revitalize the oriental health industry. So it is indespensible that government, academic institution and enterprise should concentrate their interest on the oriental health industry with common knowledge and systematic management in advance.
