Purpose : This study is a descriptive survey research in order to grasp the influence of the learning-related variable and the self-regulated learning ability upon class satisfaction given the application of online classes to nursing students. Methods : The convenience sampling was carried out in nursing students at 5 universities from June 1, 2020 to July 30. The questionnaire response data of finally 284 students were analyzed. Data analysis was used SPSS/WIN 23.0 program. Results : The class satisfaction showed a correlation with the quality of instructional content (r=.75, p=.001), the quality of class composition (r=.72, p<.001), the learner to learner mutual level (r=.39, p<.001), the student to teacher mutual level (r=.76, p<.001), the learner to content mutual level (r=.85, p<.001), the self-regulated learning ability (r=.56, p<.001). The quality of instructional content, the learner to content mutual level, and the self-regulated learning ability, which were applied to the subjects, indicated a significant impact (F=147.85, p<.001). Conclusion : An effort is considered to be necessarily made for increasing the quality of instructional content and of class composition, and for improving the online class preparation level in teachers and students through re-designing the online instructional structure.

This study is a discriptive research to identify stress and powerlessness based on Korean hemodialysis patients` constitution. Research subject was 112 hemodialysis patients who are treatment processing in P university hospital and Khemodialysis hospital in S City, and the data were collected for 60 days from December 20, 1999 to January 30, 2000. The research tools used for the measurement of constitution was QSCC Ⅱ, the measurement of the stress was Jeon chi ja`s Scale of Hemodialysis patient`s Stress(1985), and the measurement of powerlessness was Kim joe ja`s Scale of Powerlessness(1992). The reliability of the scale for stress is Cronbach`s Alpha 0.8819 and that of powerlessness is Cronbach`s Alpha 0.6993. Data analysis was performed using SPSSWin 9.0 software. We tested them with real number, percentage, average score, standard deviation, t-test, F-test(ANOVA), Pearson`s Correlation Coefficient, and Multiple stepwise regression. The results of this study were as follows: 1. Hemodialysis patients` constitution were: Soyangin 38.4%, Taemin 34.8%, and Soeumin 26.8%. 2. The average score of the stress by hemodialysis patients were the mean 89.72±20.26 points. The average score of powerlessness was the mean 34.19±6.46 points, by hemodialysis patients. 3. The result of the Pearson Correlation showed no correlation between the score of stress and the score of powerlessness. 4. In their relationship between general characteristics and the score of stress: in marriage state, job(P=0.016, P=0.007) and In their relationship between general characteristics and the score of powerlessness: in age, marriage state, educational level, job(P=0.000, P=0.012, P=0.002, P=0.050) have statistically meaningful differences. 5. The factor affecting the powerlessness of hemodialysis patients was physical area of stress and its explanatory power was 18.5%.

As the automobile energy efficiency stands out an important matter of interest, the magnetic engine valve system receives attention. It has an advantage of no engine power leakage in opening and closing the valve. Moreover, it generates much bigger force than the piezo actuator system, so it can be a good alternative system of the cam and camshaft system. However, since the valve system is not light enough, it is necessary to make its weight reduce. In this study, topology optimization is applied to find the optimal shape of the armature in a magnetic valve system combined with the finite element analysis for the magnetic field analysis. The result is used to obtain a concept design. The adjoint variable method is employed in order to calculate the design sensitivity of the magnetic driving force in the armature component mostly to reduce the computational time during the repeated sensitivity calculation. The sequential linear programming is employed for the optimization algorithm.
