Frequency stabilization of an external cavity diode laser to molecular iodine at 657.483 nm.

The saturation spectrum of the P(84) 5-5 transition of 127I2 at 657.483 nm is obtained with the third-harmonic demodulation method using an external cavity diode laser. The laser frequency is modulated by modulating the diode current instead of modulating the cavity length with a piezoelectric transducer (PZT). Current modulation allows a modulation frequency that is higher than PZT modulation. The signal-to-noise ratio of 1000 is better than previous results presented in the literature. The laser is frequency stabilized to the hyperfine component o of the P(84) 5-5 transition with a frequency stability of better than 10 kHz (2.2 x 10(-11) relative stability).

A program to enhance nursing managers' capability of operating computerized processing system.

The purpose of this program is to improve the capacities of head nurses of operating hospital information system, relevant operation of the Intranet, electronic forms, and computerized processing system through nursing information educational courses and hands-on operation. The results of questionnaires show that head nurses score averagely 4.05 on the knowledge of computerized processing system in the hospital and 3.6, the lowest, on those of schedule arrangement of nursing personnel, cashier, and accounting operation. In addition, the knowledge of the Intranet operation scored averagely 4.28 and 3.8 on the operation of electronic forms and equipment maintenance and repairing request. After collecting, analyzing, compiling information and comparing to literature review, the researchers conclude the solutions as: (1) conducting nursing information training courses to improve knowledge of head nurses on relevant computerized processing system; (2) monitoring and evaluating nursing administration to promote heads-on evaluation operation for furthering understanding of individual operation problem. After the implementation of above proposed program, head nurses score 4.99 on the knowledge of hospital information and operation of relevant intranet system and demonstrate 88% of satisfaction level indicating the importance of conducting nursing information training courses to effectively improve computer operation capacity, work efficiency, and satisfaction level.
