Mokpo National Maritime University's Maritime College operates education and training programs that allow students to adapt to the specifics of ships and the oceans. The purpose of this study is to investigate the effect of student satisfaction on core competencies and self-directed competency through the operation of socially customized education programs. We surveyed the leaders in industry-university cooperation+ education programs, and selected TALK+, an education program capable of statistical analysis, as the focus of our analysis. The TALK+ program connects people in charge of communication with those in charge of reflecting the peculiarities of maritime universities. Data were collected using satisfaction surveys that returned 259 results. These were analyzed using a 5-point Likert scale that showed a high level of satisfaction with an average of 4 points or more. The satisfaction level showed that there is positive correlation between satisfaction levels and core competency and self-directed competency. In addition, a linear regression analysis was performed, and the results showed that satisfaction has a statistically significant effect on the improvement of core competencies and self-directed competencies (p<0.001). Through this study, it was confirmed that efforts to improve the satisfaction level and develop various comparisons method and programs are necessary.

Dynamic pricing refers to a system in which a tariff varies, according to a level of charging and applied time depending on time change. The power billing system used in the Korean Electric Power Corporation (KEPCO) is based on time of use (TOU) pricing, which is one of the dynamic pricing systems. This paper aimed to determine the operational results of a variable refrigerant flow system, to which a new control algorithm was applied, in order to respond to dynamic pricing, in summer and the utility of the new control. To do this, real measured data was acquired from a VRF system installed in a building for educational purposes, where dynamic pricing was applied for about 100 days during summer time. At the maximum load operation time period in TOU, the new control minimized operation within the indoor comfort range, an increase in refrigerant evaporation temperature in the indoor unit and the number of revolutions in a compressor in the outdoor unit was limited. As a result, power usage was decreased by 11%, and the operational cost by 14.6%. Furthermore, measurement results using the Predicted Mean Vote (PMV) model, that represented satisfaction of thermal environment, showed that 82.8% to 90.4% of the occupants of the building were satisfied during operation when the new control was applied.

This was a descriptive study aiming to verify the effects of work environment, job satisfaction, and organizational commitment on the turnover intention of Clinical Research Coordinator(CRC) nurses. In the results of this study, the organizational commitment had significant effects on the turnover intention of CRC nurses. On the other hand, the work environment and job satisfaction had no statistically significant effects on the turnover intention of CRC nurses. Based on the results of this study, the main discussions were drawn as follows. In order to increase the organizational commitment, it would be necessary to have the institutional improvement like the increase of opportunity to participate in the hospital operation, administration, and the establishment of affiliated institution for improving a sense of belonging. It would be also necessary for each hospital to establish the standard of welfare, wage system for the improvement of work environment. If the organizational commitment of CRC nurses who are the actual performers, supporters of researches is ignored, it is unavoidable that the performance and quality of clinical tests would be declined. Therefore, there should be some changes, so that CRC nurses could play a pivotal role in the whole process of clinical test, by changing the employment status from contract position to more stable employment status, to increase their commitment to organization and work continuity.
