The purpose of this study is to develop a facility management package with AutoCAD SQL Extension. The output of this study can be used to overcome the current limitations of facility management. As the case study, the package is going to be applied to the Kwanak Campus of Seoul National University so as to test the usability of this package. The outcome of this research has several merits, as follows : First, the efficiency in facility management is increased by means of rapid conversion between graphic and non-graphic data. Second, it is possible to manage facility with numeric, locational precision and three dimensional display ability which are merits of CAD. Third, increasing the use of digital map in the time of facility construction, if the database for this is constructed, the developed package can be applied immediately to the affairs of facility management department.

This paper analyzed the phase noise characteristics of frequency-shifting module by figuring out the relationship between the phase noise components of 1st and 2nd local oscillator composing the frequency-shifting module and those of RF output signals shifted in frequency. Also, frequency-shifting module with the improvement of the phase noise performance was designed and implemented by means that the phase noise components of 1st local oscillator were cancelled in the output signal. Output signal has been affected by only phase noise of 2nd local oscillator, which had excellent phase noise performance than that of the 1st local oscillator.
