This study provides empirical evidence on characteristics of foreign and domestic acquisitions of Ｕ.Ｓ. manufacturing companies. Specifically, the study examined and compared the five-year premerger profile of 37 and 343 Ｕ.Ｓ. manufacturing companies, that were acguired in the 1980s by foreign and domestic companies, respectively. The profile was analyzed in terms of various company attributes. The ＡＮＯＶＡ results indicate that foreign acquirees did not change as significantly as did domestic acquirees in the five years before merger. Also, differences between the two groups of acquirees were tested. The t-test results show that foreign acquirees were less profitable, more liquid in terms of cash flows but significantly less liquid in terms of working capital, significantly more leveraged, less efficient in assets turnover, paying significant more dividend, significantly less growing, much smaller, and more actively traded than domestic acquirees.

Triplet Ionospheric Observatory (TRIO) CubeSatforIon, Neutral, Electron MAgneticfields (CINEMA) is a CubeSat with the weight 3 kg that will be operated in the orbit conditions of about 800 km altitude and 90° inclination angle, using the S-band and ultra-high frequency (UHF)-band communication frequencies. Regarding the communication antenna loaded on the satellite, the two patch antennas has the downlink function in the S-band, whereas the two whip antennas has the function to receive the command sent by the ground station to the satellite in the UHF-band. The uplink ground station that communicates through the UHF-band with the CINEMA satellite was established at Kyung Hee University. The system is mainly composed of a terminal node controller, a transceiver, and a helical antenna. The gain of the helical antenna established at the Kyung Hee University ground station was 9.8 dBi. The output of the transceiver was set to be 5 W (6.9 dB) for the communication test. Through the far-field test of the established system, it was verified that the Roman characters, figures and symbols were converted into packets and transmitted to the satellite receiver in the communica\-tion speed of 9,600 bps.
