Purpose : This study aimed to identify the factors influencing job satisfaction in intensive care unit (ICU) nurses. Method : Using a cross-sectional design, data collected from 145 ICU nurses working at two university hospitals with more than 1,200 beds located in B and Y city were analyzed. The instruments used for this study assessed autonomy, communication satisfaction, resilience, and job satisfaction. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and multiple linear regression analysis. Results : Job satisfaction was significantly correlated with communication satisfaction (r=.60, p < .001) and resilience (r=.34, p < .001). Further, job satisfaction was influenced by communication satisfaction (${\beta}=.48$, p < .001), working at a surgery ICU (${\beta}=.21$, p =.008), and dissatisfaction with nursing (${\beta}=-.24$, p =.005). The explanatory power of this model was 44.7%. Conclusion : These results suggest the need for programs to improve communication satisfaction and nursing satisfaction.

Purpose: This study was intended to examine the effects of educating the Ventilator-Associated Pneumonia (VAP) control for the nurses working in the intensive care unit (ICU). Methods: The study was conducted using one group pre-post test research design. The education on infection control was provided to 31 nurses working at the medical and surgical ICUs. A comparison was then made in terms of the degree of performing infection control a month before, two weeks after, and three months after the education respectively. The incidences of VAP at the medical and surgical ICUs were compared for 3 months before and after the education. Results: The average performance scores between before and after the education showed statistically significant differences. Compared to three months before, the incidence of VAP after the education was decreased slightly from 5.48 to 1.88 per 1,000 ventilator days. Conclusion: It is necessary to continue the VAP education, specifically on infection prevention and control methods and the consistent evaluation of its effects as well as the development of standardized educational program should be approached extensively in further studies.

Purpose : This study compares experiences of ethical dilemma between nurses working in intensive care units and those in general units under specific situations of treatment decisions and confidentiality. Method : This cross-sectional descriptive study utilizes the self-report survey method. The survey questionnaires were completed by 50 and 52 nurses working in intensive care units and general units, respectively. The instrument, which consisted of 16 items of ethical dilemma situations about treatment decision and confidentiality, was used. The mean scores for each item were compared between the two groups. Results : The study found no differences in terms of age, gender, education level, clinical experience in years, and being educated on healthcare ethics. For 9 out of 16 items, the mean scores of nurses in intensive care units were significantly higher than those of nurses in general units. Conclusions : Nurses in intensive care units experienced ethical dilemmas regarding treatment decisions and confidentiality more often than those in general units. This study emphasizes the need to establish strategies for improving the ethical competence of critical care nurses.

In this paper, the design and implementation of a multiprocessor based Die Bonder Machine for the semiconductor will be described. This the partial research result, that is, the 1st year portion of the project to be performed for a period of two years from June, 1986 to May, 1988. The mechanical system consists of the following three subsystems : (i) transfer head unit, (ii) die feeding XY-table unit, and (iii) plunge up unit. The overall control system is designed to be essentially a master-slave type in which each slave is functionally fixed in view of software and also the time shared common bus structure with hardwired bus arbitration scheme is utilized, the control system consists of the following three subsystems each of which employs a 16 bits microprocessor MC 68000 : (i) die bonder processor controller, (ii) visual recognition/inspection and display system, (iii) the servo control system. It is reported that the proposed control system were applied to Working Sample and tested in real system, and the results are successful as a working sample phase.

Purpose: This was a descriptive observational study examining the reasons for, frequency of, and factors affecting work interruption among intensive care unit (ICU) nurses. Methods: Convenience sampling was used to recruit 46 regular nurses who had been working in an ICU at D tertiary hospital in B metropolitan city for at least six months. To measure the degree of work interruption, this study revised a tool used by Brixey et al. (2007) for analyzing the type of work interruption. Results: A total of 1,787 work interruptions occurred during 368 hours of observation, i.e., at an average of 4.85 times per hour. Communication-related factors caused work interruption most frequently, followed by environmental, work-related, and personal factors. As for the work-related characteristics of nurses, participants experienced work interruption more frequently while working on weekdays, when the medical staff were stationed, than on weekends. Conclusion: ICU nurses experienced work interruption frequently. With the health care system expected to become more complicated in the future, efforts should be made to reduce unnecessary work interruptions to improve the operation efficiency of ICUs.

Purpose: Preventing missed care is important in neonatal intensive care units (NICUs) due to neonates' vulnerabilities. This study examined missed care and its influencing factors among NICU nurses. Methods: Missed care among 120 Korean NICU nurses was measured using a cross-culturally adapted online questionnaire. The frequency of missed care for 32 nursing activities and the significance of 23 reasons for missed care were collected. Results: All participants had missed at least 1 activity, missing on average 19.35 activities during a typical work-day. The most common missed item was "provide developmental care for the baby". The most common reason for missed care was "emergency within the unit or deterioration of one of the assigned patients". The final regression model explained 9.6% of variance in missed care. The average daily number of assigned patients receiving inotropes or sedation over the last month influenced the total number of missed care items. Conclusion: Missed care was affected by nurses' workload related to the number of patients taking medication. Frequently missed activities, especially those related to developmental care, require patience and time, conflicting with safety prioritization and inadequate working conditions. NICU nurses' working conditions should be improved to ensure adequate time for nursing activities.

This paper presents design solutions for cam type transfer unit in which feeding, lifting, and clamping motions are generated by cams. In order to achieve faster transfer motion, each designed cam must satisfy the given specifications such as velocity, acceleration, jerk, pressure angle, cam thickness, and torque. To reduce absolute torque magnitude and torque variation, a conjugate cam and a torque reduction cam are used respectively. The conjugate cam eliminates the redundant pre-load by using complementary cam to avoid jumping between a cam and a follower. The torque reduction cam reduces the torque variation by applying opposite torque to a cam shaft. The experimental result shows the reductions of the absolute torque value and torque variation. The improvement of working speed and life span of cam type transfer unit can be expected.

The spindle unit is core parts in high precision machine tools. Diverse static and dynamic charateristics of spindle unit are needed for special purpose of machine tools. Specially, high damping ability may be very useful to high precision and high speed spindle unit. But commercial bearing system has very low damping value and high stiffness. In this paper, the combined bearing system with ball-hydrostatic bearing is suggested for high damping spindle unit. The suggested bearing system has 30% damping ability more than general ball bearing's. The average rotational accuracy of spindle with combined bearing in working speed is 24% better than with ball bearing. The unbalance rotating experiment in spindle show that rotating error with combined bearing is only half value of with ball bearing.
