This paper analyzed the effect of job search channels on the occupational adaptation of college graduates, with the Graduates Occupational Mobility Survey(GOMS) data. The analysis results are as follows: First, when using human networks for getting jobs, not only the educational level and major adequacy, but also the workplace satisfaction and the job satisfaction were higher than when using non-human networks. Second, as in the mediating effect of the relationship between job search channels and occupational adaptation by Sobel-test, it was found that there was a partial mediating effect of educational level and major adequacy, excluding skill level adequacy. The results of this study shows that human networks, by serving as an effective information transmitter on person-job fit between job search and recruitment, contribute significantly to improve occupational adaptation of college graduates. These results imply that strategic utilization of human networks in job search activities is important, and that it is necessary that career-related programs in the universities or the employment service institutions systematically include the importance and methods of using human networks.

Measuring magnetic fields with a SQUID sensor always requires preliminary adjustments such as optimum bas current determination and flux-locking point search. A conventional magnetoencephalography (MEG) system consists of several dozens of sensors and we should condition each sensor one by one for an experiment. This timeconsuming job is not only cumbersome but also impractical for the common use in hospital. We had developed a serial port communication protocol between SQUID sensor controllers and a personal computer in order to control the sensors. However, theserial-bus-based control is too slow for adjusting all the sensors with a sufficient accuracy in a reasonable time. In this work, we introduce programmatic control sequence that saves the number of the control pulse arrays. The sequence separates into two stages. The first stage is a function for searching flux-locking points of the sensors and the other stage is for determining the optimum bias current that operates a sensor in a minimum noise level Generally, the optimum bias current for a SQUID sensor depends on the manufactured structure, so that it will not easily change about. Therefore, we can reduce the time for the optimum bias current determination by using the saved values that have been measured once by the second stage sequence. Applying the first stage sequence to a practical use, it has taken about 2-3 minutes to perform the flux-locking for our 37-channel SQUID magnetometer system.
