This study has been done for the purpose of investigating the degrees of death orientation and terminal care performance. The factors related to these two variables, and the relationship between death orientation and terminal care performance. The subjects of study were 128 nurses who implemented nursing care for terminally ill patients at C University Hospital in Kwang Ju city. The data were collected from March 13 to 19, 1996, by means of Death Orientation by Thorson Powell(1988) and Terminal Care Performance Scale by researcher. The data were analysed by t-test, ANOVA, Duncan test and Pearson's correlation coefficient. The Results of this study were summarized as follows : 1. The mean score of death orientation was 61.4. The degree of death orientation showed no significant difference depending on the general characteristics of nurses. 2. The mean score of terminal care performance was 45.5. In comparison of the degree of terminal care performance among three domains, the mean score of each item tended to show higher degrees in order of 'Psychological domain(2.4)', 'Physical domain(2.2)', 'Spiritual domain(1.9)'. 3. The degree of terminal care performance showed significant differences in age(F=11.48 p=.0001), marital status(t=10.49 p=.0015), religion(t=5.01 p=.0270), period of clinical experience(F=10.30 p=.0001) and ward unit(F=3.73 p=.0036). The degree of terminal care performance in physical domain showed significant differences in age(F=7.26 p=.0010), marital status(t=9.72 p=.0023), period of clinical experience(F=7.03 p=.0013), ward unit(F=6.23 p=.0001). The degree of terminal care performance in psychological domain showed significant differences in age(F=8.73 p=.0003), marital status(t=4.22 p=.0419), religion(t=5.59 p=.0196), period of clinical experience(F=6.36 p=.0023), ward unit(F=3.33 p=.0075). The degree of terminal care performance in spiritual domain showed significant differences in age(F=8.30 p=.0004), marital status(t=10.45 p=.0016), religion(F=5.41 p=.0216), period of clinical experience(F=8.80 p=.0003). 4.

The decoupling design for the one-degree-of-freedom controller system is treated within the $H_{\infty}$ framework. In the present study, we demonstrate that the $H_{\infty}$ performance problem in the decoupling design is reduced into interpolation problems on scalar functions. To guarantee the properness of decoupling controllers and the overall transfer matrix, the relative degree conditions on the interpolating scalar functions are derived. To find the interpolating functions with relative degree constraints, Nevanlinna-Pick algorithm with starting function constraint is utilized in the present study. An illustrative example is given to provide details regarding the solution.

The purpose of this study is to investigate the impact of internationalization on the business performance of firms in Laos as a transition economy. Using a panel dataset collected by the World Bank for 285 firms during the period 2009, 2012, and 2016 in the service and manufacturing industries, the two-steps Heckman regression results found robust evidence for the fact that the S-curve tie exists between the degree of internationalization and business performance of firms in Laos while controlling other factors. Specifically, if firms have a degree of internationalization lower than 0.4374, they will suffer losses due to the high cost of preparing for phase 1 which is market penetration. Then, when the degree of internationalization continues to increase from 0.4374 to 0.9131, firms will gain benefits from internationalization (phase 2), however, these benefits will deteriorate when the degree of internationalization is greater than 0.9131 (phase 3), meaning that firms will no longer be able to exploit economies of scale or advantages in target markets, or product cycles will fall into a state of decline. Interestingly, we also found that firms with a high concentration level of ownership and internationalization activities may achieve better performance than those with a low concentration of ownership and one which carried out internationalization activities.

Herein we investigated the effect of the conductive agent on the electrochemical performance of the SiOx anode. SiOx anodes have a relatively low volume expansion (~160%) compared to Pure-silicon, but have a problem in that they have a poor electrical conductivity characteristic. In this study, physical and electrochemical measurements were performed using two 0-dimensional amorphous carbon conductive agents with different crystallinity and surface area. The crystal structure of the conductive agents and the local graphitization degree were analyzed through XRD and Raman, and the surface area of the particles was observed through BET. In addition, the electrical performance according to the graphitization degree of the conductive agents was confirmed through a 4-point probe. As a result of the electrochemical cycle and rate performance, it was confirmed that the performance of SiOx using a conductive agent having a low graphitization degree and a high surface area was improved. The results in this study suggest that the graphitization degree and surface area of the amorphous carbon conductive agent may play an important role in the SiOx electrode.

Background: This study was to survey the effect of the degree of spiritual nursing care performance on the spiritual nursing care ability of the nursing students Methods: The researcher sampled 130 nursing students for a questionnaire survey conducted from September 17 until September 27, 2018. The data of analysis used SPSS 23.0 program. Results: The spiritual nursing care ability was $4.4{\pm}0.8$(total score 6) and the degree of spiritual nursing care performance was $2.9{\pm}1.8$(total score 4). The spiritual nursing care ability differed significantly depending on religion(F=7.570, p<.001), the level of spiritual nursing knowledge(F=19.873, p<.001), education type(F=14.626, p<.001), necessity of hospice(t=2.280, p=.024). The degree of spiritual nursing care performance differed significantly depending on spiritual nursing education time(F=2.932, p=.036). The correlation of two variable was statistically significant difference(r=.206, p=.019). The influencing factors on the spiritual nursing care ability was religion, the level of spiritual nursing knowledge, education type, dying experience($R^2=0.378$, Adj $R^2=0.353$), the degree of spiritual nursing care performance was spiritual nursing education time($R^2=0.065$, Adj $R^2=0.043$). Conclusion: These results show that nursing students are not able to perform spiritual nursing care properly to subjects who need spiritual nursing care. Therefore, it is necessary to develope programs to meet the spiritual nursing care needs of nursing students and to provide practical education in accordance with the program by cooperating with the nursing education staff, clergy and clinical nurse etc. And spiritual nursing care should be taught as a required subjects in the curriculum.

The purpose of this study was to identify the negative factors affecting personnel u-Learning acceptance and to analyze the interrelation among the factors in this research model. The two independent variables avoidable convenience and reliant convenience, based on pilot test results, and learning performance and perceived interactivity, based on the relevant literature, are used to examine the research model. The research problem was tested with data collected from 577 respondents in 23 universities. This study developed and empirically analyzed a model representing the relationship by using the Structural Equation Model. The major findings of this study are, firstly, that the higher reliant convenience is negatively affecting the degree of system use and learner’s satisfaction, whereas avoidable convenience is only affecting the learner’s satisfaction. Secondly, the higher learning performance and stronger perceived interactivity affects the degree of system use as well as learner’s satisfaction. Finally, the degree of system use affects the learner’s satisfaction.

In this paper, cycle performance analysis of two-stage compression and two-stage expansion refrigeration system using alternative freon refrigerants is presented to offer the basic design data for the operating parameters of the system. Alternative freon refrigerant for freon refrigerant R22 were used as working fluids in this study. The operating parameters considered in this study included evaporation temperature, condensation temperature, subcooling degree, superheating degree, and mass flow rate ratio of inter-cooler. The main results were summarized as follows : The COP of two-stage compression and two-stage expansion refrigeration system increases with the increasing subcooling degree and mass flow rate ratio of inter-cooler, but decreases with the increasing evaporating temperature, condensing temperature and superheating degree. Therefore, subcooling degree, mass flow rate ratio of inter-cooler of two-stage compression and two-stage expansion refrigeration system using alternative freon refrigerants have an effect on COP of this system.

Cracking of concrete cover induced by reinforcement corrosion is a critical issue for life-cycle design and maintenance of reinforced concrete structures. However, the critical degree of corrosion, based on when the concrete surface cracks, is usually hard to predict accurately due to the heterogeneity inherent in concrete. To investigate the influence of concrete heterogeneity, a modified rigid-body-spring model, which could generate concrete sections with randomly distributed coarse aggregates, has been developed to study the corrosion-induced cracking process of the concrete cover and the corresponding critical degree of corrosion. In this model, concrete is assumed to be a three-phase composite composed of coarse aggregate, mortar and an interfacial transition zone (ITZ), and the uniform corrosion of a steel bar is simulated by applying uniform radial displacement. Once the relationship between radial displacement and degree of corrosion is derived, the critical degree of corrosion can be obtained. The mesoscale model demonstrated its validity as it predicted the critical degree of corrosion and cracking patterns in good agreement with analytical solutions and experimental results. The model demonstrates how the random distribution of coarse aggregate results in a variation of critical degrees of corrosion, which follows a normal distribution. A parametric study was conducted, which indicates that both the mean and variation of critical degree of corrosion increased with the increase of concrete cover thickness, coarse aggregates volume fraction and decrease of coarse aggregate size. In addition, as tensile strength of concrete increased, the average critical degree of corrosion increased while its variation almost remained unchanged.
