The purpose of this study was to investigate the factors affecting job satisfaction of nurses in nursing care service ward. The subjects were 127 nurses, nursing job satisfaction, nursing intuition, and nursing work environment using the 5 - point Likert scale. Data were analyzed by t-test, ANOVA, correlation and regression analysis using SPSS WIN 23.0 program. The results showed that the correlation between job satisfaction and independent variables in nursing and nursing care service ward was significant in nursing professionalism (r = .90, p <.001) and nursing work environment (r = .75, p <.001). In addition, factors affecting job satisfaction were in the order of nursing professionalism and nursing work environment (F = 31.516, p <.001), and explanatory power was 84.1%. Therefore, Therefore, the necessity of nursing convergency strategy for improvement of these is suggested.

Vibration test on MAST(multi axial simulation table) system has several advantage over one-axial vibration test that could simulate 6-DOF, 3-axial translation and 3-axial moment, at the same time. Since field vibration motion can be fully represented with 6-DOF, multi-axial vibration test on vehicle component is widely conducted in technical leading companies to make sure its fatigue performance in vibration environment. On the way to fulfill the process, editing technique of obtained field data is key issue to success a reliable vibration testing with MAST system. Since the original signals are not only too large to fulfill it directly, but all of the measured data is not guarantee its convergency on generating its driving files, editing technique of the original signals are highly required to make some events that should meet the equal fatigue damage on the target component In this paper, key technique on editing a field data feasible for MAST system is described based on energy method in vibration fatigue. To explain its technique explicitly, author first introduced a process on field data acquisition of two vehicle component and then, representing events are produced to keep up with the editing strategy about a energy method. In the final chapter, a time information regarding a vibration test on MAST system is derived from the energy data which is critical information to perform a vibration test.

In the present study, we investigated the characteristic of growth and the tolerance of cold temperature in small yellow croaker and yellow drum. The results shows that the growth of yellow drum were faster than those of small yellow croaker with high food convergency efficiency. In condition factor (CF), the results shows that the values of yellow croaker and yellow drum were significantly higher in September, respectively. In mortality according to cold shock, two fishes was died under $4.7^{\circ}C$ in slow temperature descending test, but was both died under $9^{\circ}C$ in acute temperature descending test.

Although there are usual security threats caused by the characteristics of cloud services, more public institutions plan to introduce the cloud services rapidly, as the increase of recognition for its advantage. The previous studies have focused on the security threats and the quality as a hindrance of activation of cloud services. Those also have stressed the importance of the quality in the cloud user side. But there was no consideration about which quality factors impact on the satisfaction of users. Therefore, this study analyzed the importances of quality in specific five major factors. The results also presented that the SLA guarantee is more important than the security performance. This research will contribute to cloud services providers in Korea, by aiding the establishment of effective quality strategies.

ICT convergence has attracted attention as a major means of corporate innovation. In this study in-depth interviews was had to analyze the success factors of ICT-based companies that created a performance through the convergence. The success factors of ICT convergence were analyzed by differentiating your company's products and services through the integration of ICT skills, securing convergence technologies with enhanced R&D investment, and the strong leadership of CEO and collaborative relationships at home and abroad for convergence. It is a positive impact on success of ICT convergence to try the innovations in products, to invest R&D aggressively and to construct a global partnership network. As these results, they was proposed as a policy direction for the diffusion of ICT convergence.

This study explored the effects of adoption of innovation and resistant attitude on farmers' perspectives and also was deigned for developing prompt spread of ICT and facilitating stronghold support center in the convergence agricultural field. To closely examine the variation for exploitation intent of stronghold support center in the ICT convergence agriculture, 110 farmers who had experienced introduction for ICT hybrid environmental control system were participated in the study using the questionnaire. The results revealed the several findings. Firstly, there was no significant differences between the self-efficacy such as confidence of application technology for farmers and adoption of innovative technique (p=.075). Secondly, suitability of using ICT hybrid environmental control system showed a significant difference in the adoption of innovation (p=2.750) while complexity of using ICT hybrid environmental control system indicated the negative effects on the adoption of innovation (p=3.591). Thirdly, introduction cost of ICT hybrid environmental control system showed the negative effects in the adoption of innovation (p=2.278), whereas adoption of innovation indicated a significant difference in the stronghold support center in the convergence agricultural field (p=5.500). Finally, resistance of ICT adoption of innovative technique revealed the negative effects on the stronghold support center in the ICT convergence agriculture. This study, therefore, demonstrated that educational assistance for acquiring ICT technique, suggestion of influences for productivity, and development for skills were needed to extend ICT convergence technology.

The algorithm Proposed utilizes the two-levels technique. In the first level which consists of two phases, the cross-sectional area of the truss member is optimized by transforming the nonlinear problem into SUMT, and solving SUMT utilizing the modified Newton-Rahson method. In the second level, the geometric shape is optimized utilizing the unindirectional search technique of the Powell method which make it possible to minimize only the objective function. The algorithm Proposed in this study is numerically tested for several truss structures with various shapes, loading conditions and design criteria, and compared with the results of the other algorithms to examine its applicability and stability. The numerical comparisons show that the two-Levels algorithm Proposed in this study is safely applicable to any design criteria, and the convergency rate is relathely fast and stable compared with other iteration methods for the geometric optimization of truss structures.

In the current lighting market, LEDs that have a high luminous efficiency, a long life and consume less power have emerged as next generation lighting. Owing to various designs and sizes of LEDs, the production process of existing LEDs involves many tasks that require manual labor; hence, the assembly of LEDs necessitates manpower. Because of the use of manpower, the production costs of LEDs increases and production efficiency decreases. Recently, the assembly parts of LEDs have been standardized for minimizing manual labor, and an LED is developed as an LED panel. The automatic assembly system produces LED convergent lighting by assembling two LED panels and one diffusion cover. To increase the production efficiency of the LED convergent lighting module, it is important that the development of a feeder can continuously supply the LED panels is required, and whose design has sufficient stability. The automatic assembly system of the LED convergent lighting module consists of two feeders, which convey LED panels and diffusion covers to a main conveyor, which assembles the lifted panels and covers. In this study, structural analysis and fatigue life for forced loads on the conveyer line of the feeder in the process of lifting LED panels and diffusion covers of each feeder, is analyzed. In addition, the drive of the belt constituting the conveyor line of each feeder is simulated, and the dynamic characteristics of the belt is analyzed using the virtual engineering method.
