In this paper, we propose the hardware and software of a test-bed of a hovering AUV (autonomous underwater vehicle). Test-bed to develop as the underwater robot for the hovering -type is planning to apply for marine resource development and exploration for deep sea. The RTU that controls a azimuth thruster and a vertical thruster of test-bed is a intergrated-type thruster. The main control unit that collects sensor's data and performs high-speed processing and controls a movement of test-bed is a underwater hybrid navigation system. Also it transfers position, posture, state information of test-bed to the host PC of user using a wireless communication. The host PC checks a test-bed in real time by using a realtime monitoring system that is implemented by LabVIEW.

Design considerations of I2L are discussed with particular emphasis on the upward current gain of the npn transistor, 6J Several test structures have been fabricated to measure the DC and AC characteristics of the I2L basic cell and the base current components of the npn transistor. A T flip-flop has also been designed and fabricated using the I2L technology. The upward current gain of 10 the speed -power product of the 2.6pJ/gate and the minimum propagation delay time of 36 nsec have been obtained from the test structure. The maxmum toggle frequency of the T flip -flop has been measured to be 3.5 MHz.

The sacroiliac joint is difficult to appropriately examine and treat because it is extremely complex and also is difficult to distinguish dysfunctions from those of the spine and hip which are highly intergrated functionally. In addition generally traditional x-rays and CT scans also are not beneficial in detecting sacroiliac joint dysfunction. The manipulative physiotherapist should seek to establish a series of relevant finding that build into a case implicating the sacroiliac joint. When deciding to use these diagnostic tests, the examiner must determine if the test will give reliable and useful information that will help in the diagnosis and subsequent treatment. To be useful diagnostic tests must give reliable data and be valid and the most useful methods of determining whether a test is a good test for pathology under consideration are sensitivity and specificity. In the ideal world, one would want a test that has both high sensitivity and high specificity. The purpose of this review is to ascertain diagnostic value on the tests for sacroiliac joint dysfunction by literature.

VLSI intergrated circuits like SOC(system on chip) often require a multi-clock design style for functional or performance reasons. The problems of the clock domain transition due to clock skew and clock ordering within a test cycle may result in wrong results. This paper describes a new BIST(Built-in Self Test) architecture for multi-clock systems. In the new scheme, a clock skew is eliminated by a multi-capture. Therfore, it is possible to perform at-speed test for both clock inter-domain and clock intra-domain.

There exist a lot of factors and restrictions for the design of solid rocket motors like burning rate, of solid propellant, demanded thrust, chamber pressure, diameter, length, weight and acceleration. For the optimization of these factors and restrictions, integrated design software for internal/external ballistic analysis was developed and verified by the performance test of solid rocket motors.

Purpose - The current study analyzes effects of hotel restaurant cook's emotional labor on job satisfaction and customer orientation. Research design and methodology - In order to achieve the current study's goal, sample was extracted targeting cooks working in 5-stars hotels located in Seoul considering spatial and time limitation. Method of research was direct research method with survey. Survey was conducted from April 1st, 2018 to April 20, 2018 (approximately 20 days). Total of 300 surveys were distributed to cooks working in 5-stars hotels located in Seoul, and among those 250 surveys were returned. Among returned 250 surveys, 246 surveys. Results - First, in order to test H1, effect of hotel restaurant cook's emotional labor on job satisfaction (satisfaction on superior and coworker) was analyzed. Second, in order to test H2, effect on hotel restaurant cook's emotional labor on job satisfaction (satisfaction on compensation and promotion) was analyzed. Third, satisfaction on superior and coworker had statistically significantly positive effect on customer orientation, while satisfaction on compensation and promotion did not have statistically significant effect. Conclusions - First, deep acting had statistically significantly positive effect on job satisfaction (satisfaction on superior and coworker), while surface acting did not have statistically significant effect. Second, both deep and surface acting had statistically significantly positive effect on job satisfaction (satisfaction on compensation and promotion). Third, satisfaction on superior and coworker had statistically significantly positive effect on customer orientation, while satisfaction on compensation and promotion did not have statistically significant effect.

This study intended to analyze the effectiveness to obtain by developing the critical pathway presented as the method to improve the quality-betterment and cost effectiveness the through the continuous and consistent patient management for the hysterectomy patient and applying it to the real practice. This study was designed to develop and effect the critical pathway for hysterectomy patients in the way to be possible the intergrated in patient management. It was adopted the process of seven phase to develop a critical pathway. To analyze the application effect of the developed critical pathway, this author offered health care service applying the critical pathway to the hysterectomy patient from July. 20 to Oct. 19. 1999. The study method had been done by investigating the experimental group and control group through the questionnaire on 40 patients who had been inpatient hysterectomy. Dependent variables were measured by modified from satisfaction, and cost and length of hospital stay. The data anlyzed by frequency, x2-test, t-test. The results of this study was as follows; 1. It was decided that the vertical line of the critical pathway was made up of eight items such as monitoring/assessment, treatment, activity, medication, consult. Lab test, diet, patient teaching and horizontal line was 7days from admission to discharge. 2. After the verifying the validity of the expert group about the critical pathway, the horizontal line was amended from hospitalization to five postoperative days and taking their consensus, some contents of the horizontal line was amended and deleted. 3. There was no significant differences in the experimental group and control group in the satisfaction, and significant differences in the cost, the length of hospital stay.
