For the simplification of doping process in amorphous carbon film, arsenic (As) ions were implanted on the nucleated silicon wafer before the growth process. Then amorphous carbon films were grown at the condition of $CH_4/H_2=5%$ by microwave plasma chemical vapour deposition. Because the implanted seeds were grown at the high temperature and the implanted ions were spread, it was possible to reduce the process steps by leaving out the annealing process. When the implanted amorphous carbon films were electrically characterized in diode configuration, field emission current of $0.1mA/cm^2$ was obtained at the applied electric field of about $2.5V/{\mu}m$. The results show that the implanted As ions were sufficiently doped by the self-annealing process by using the growth after implantation.

This study proposes the Field Oriented Capacity Upgrade Program, an educational model for improving clinical practice of occupational therapy. The effectiveness of the self-directed learning ability and problem solving ability of students was compared by comparing the proposed educational model with the traditional teaching method. The research method was divided into the experimental group who participated in the model education and the control group who participated in the lecture class, and conducted similar experimental studies using the nonequivalent control group pretest-posttest design. In addition, the study participants conducted a preliminary and follow-up survey of a total of 135 students who participated in the education over three semesters. As a result of training using the proposed learning method, the experimental group improved self-directed learning ability and problem solving ability by 22% and 18%, respectively, compared to the control group. This study developed and proposed a new teaching-learning method to improve clinical practice of occupational therapy, and it is meaningful as a basic data of teaching-learning method to improve the ability required in various jobs.

The purpose of this study is to explore the impact of cultural capital on individuals and society, and to demonstrate the causal relationship between cultural capital and viewing loyalty. Existing studies conducted from a cultural sociological point of view have mainly linked cultural capital to social inequality issues, so the role of cultural capital in personal life and social life has not received attention. To fill this literary gap, this study explored the role of cultural capital centering on the art field. A structural equation model was used to test the research hypotheses, and data were collected for college (graduate) students from three universities in Seoul. As a result of the study, it was found that artistic cultural capital had a significant effect on self-image in the field of personal life. In addition, it was found that artistic cultural capital had a positive effect on tolerant attitudes in the field of social life. Finally, it was found that viewing loyalty, which refers to favorable attitudes and behaviors toward visiting art museums, was significantly affected by artistic cultural capital. The results of this study have academic and practical implications in terms of exploring the practical role of cultural capital.

Theoretical model for membrane transport of large polye!ectroiyte is presented. When the electric field is applied, the molecular conformation quickly orients in the field direction showing overshooting orientation. the predicted dependence of overshoot time and orientation upon field intensity and molecular size aids to understand the dynamic motion of molecules in membrane transport. The dynamics of the overshoot is associated with self-trapping conformations of molecule. The understanding of these effects supports evidences for the electrophoretic filtration of polydectrolyte in the polymeric membrane. This paper shows one example for molecular study in the theoretical review paper of membrane transport.

Purpose: The purpose of this study was to investigate effects of providing written information for coronary artery disease on health behavior compliance related self-efficacy, knowledge of disease, anxiety, and educational satisfaction depending on patients' health literacy. Methods: The participants in this study were 40 patients who underwent coronary angiography or coronary intervention, and depending on the level of health literacy 30 patients were high group and 10 patients were low group. Each group was evaluated on health behavior compliance related self-efficacy, knowledge of disease, anxiety, and educational satisfaction with providing written information. Results: By providing written information in the group with high health literacy, there was a significant difference in health behavior compliance related self-efficacy, knowledge of disease, but there was no significant difference in anxiety variable. On the other hand, there was no significant difference in health behavior compliance related self-efficacy, knowledge of disease, and anxiety by providing written information in the group with low health literacy. Also, there was no significant difference in the educational satisfaction between high and low group of health literacy after providing written information. Conclusion: It is necessary to develop educational materials that can be applied to clinical nursing field with considering health literacy of patients with coronary artery disease. In addition to providing written information, it is also necessary to develop other educational intervention programs such as video and personalized counseling that may be helpful for coronary patients with low health literacy and investigate their effectiveness.

Stellar spiral arms and magnetic fields in disk galaxies are important in the formation of gaseous structures such as spurs/feathers and wiggles as well as in angular momentum transport between stars and gas. We present our recent results of global magnetohydrodynamic simulations to study nonlinear responses of self-gravitating and magnetized gas to an imposed stellar spiral potential. We vary the arm strength, the arm pattern speed, and magnetic field strength to explore various galactic situations. Magnetic fields not only reduce the peak density of galactic spiral shocks but also make angular momentum transport more efficient via magnetic pressure and tension forces. The extent and shapes of gaseous arms as well as the radial mass drift rate depend rather sensitively on the magnetic field strength. The wiggle instability apparent in unmagnetized models is suppressed with increasing magnetic field strength, while magnetic fields promote the development of magneto-Jeans instability of the arms and magnetic islands in between arms. We quantify the angular momentum transport by spiral shocks, focusing on the effects of magnetic fields. We also present physical interpretations of our numerical results and discuss astronomical implications of our findings.

The problem of poor learning has been a subject that has been constantly raised in the educational field since the mid 20th century. Therefore, this study classified the components of self - regulated learning into cognitive - control, motive - control, and behavior - control strategies, and examined the effects of self - regulated learning on internal value, self - efficacy, curiosity, and self - confidence. The study was conducted on university students who participated in the program for the study of depression in A university in Changwon city. The results showed that self - regulated learning factors had a positive effect on learning motivation. Second, the learning adjustment factors have a positive effect on self - efficacy. Finally, learning control factors have a positive effect on curiosity and self - confidence. Through this study, we confirmed that a comprehensive guidance system considering interaction is needed because various factors act integrally in the learning process. As a concrete method, it is imperative to develop a learning counseling program that can enhance the motivation level by referring to cognitive, synchronous, and behavioral factors.

This study examined the factors influencing the relationship between anger and happiness of university nursing students so that they can improve their happiness and perform their studies with better internalized values. The general characteristics, academic efficacy, self-directedness, self-resilience, anger scale, and subjective happiness of 401 nursing students were measured. The differences between these groups were analyzed using t-tests and ANOVA tests. Correlations among academic efficacy, self-directedness, self-resilience and psychological states were calculated using Pearson's correlation coefficient. Multiple group analysis was conducted for assessing the interaction effects of academic efficacy, self-resilience and self-directedness. Subjective happiness and predictors of the study (self-directedness and ego-resilience) were positively correlated with statistical significance. The lower the self-directedness was, the higher the subjective happiness that is reduced by anger was. The higher the self-elasticity, the lower the degree of the subjective happiness that is reduced by anger. Since the moderating effect of self-directedness has been demonstrated in the relationship between anger and happiness, it is necessary to consider instituting proper pedagogy so that the educational method of enhancing self-directedness can be reflected in the field of nursing.

This experiment was carried out to investigate the efficient turning method which will be able to use every cutting methods, to calculate the width of the center field which must transpose from rotary cutting method to return cutting method, to investigate the effects of L/W and unit field on the operation efficiency. The results are summarized as follows: 1. In case of cutting in the outer field, the efficient turning method is the "$\alpha$" type turning method (half U-shaped turning method) at the first rotation, is the "$\beta$" type turning method (T-shaped turning method) at the second to fourth rotation. 2. In case of cutting in the inner field, the efficient turning method which takes the least turning time is the "a" type turning method ($\Delta$-shaped turning method). 3. The width of the center field (W') changes by the length-width ratio (L/W) and width (W), W' is 9.0m in case that L/W is 2.5 and W is 30m. 4. The larger L/W and area of unit field (A) become, the more operation efficiency (E) increases, and the limits that E is affected signicantly by L/W is 2 to 3.5 and A is within 5,000$m^2$. within 5,000$m^2$.
