We have investigated the experiments in which fabrication and characterization of single-electron transistors were conducted due to easy fabrication and high functionality. In the Fe-MgF2 granular film, in which Fe grains are distributed between insulators instead of the conventional quantum dots, it can be easily fabricated by EB deposition alone, and various output values can be expected by applying two or more gate voltages. The tunneling thickness of the film for single-electron operation was investigated and it was confirmed that the tunneling occurred at 2.1 nm.

To enhance the performance of anode-supported SOFC, single cell fabrication procedure was changed for better and resulting power generating characteristics of single cell were investigated. Liquid condensation process was employed for the granulation of NiO/YSZ powder mixture and the produced powder granules were compacted into anode green substrate by uni-axial pressing. YSZ electrolyte was printed on green substrate via screen-printing method and co-fired at 1400$^{\circ}C$ for 3 h. LSM/YSZ composite cathode of which the composition and heat treatment condition was adjusted to minimize the polarization#resistance with AC-impedance spectroscopy, was screen printed. The final single cell size from this multi-step procedure was 5${\times}$5 $\textrm{cm}^2$ and 10${\times}$10 $\textrm{cm}^2$. The maximum power densities of 5${\times}$5 and 10${\times}$10 single cells were about 0.45 W/$\textrm{cm}^2$ and 0.22 W/$\textrm{cm}^2$ at 800$^{\circ}C$, which are two times superior than those from single cells fabricated by the conventional process in previous our work.

This study was performed to examine the effects of Dan Jeon Breathing on stress, sleep disturbance and self-esteem of hemodialysis patients. This study used the nonequivalent control group pretest-posttest design. Before applying the Dan Jeon Breathing program, the patients were divided into the experimental group and the control group, respectively, and were requested to report their self-ratings to measure their stress, sleep disturbance and self-esteem. The Dan Jeon Breathing program was given to experimental groups for 60 minutes a day and 2 times a week for 12 weeks. The data collected from the program were analyzed by means of ${\chi}^2$ test, Fisher's exact probability test, Shapiro-Wilk and t-test. The analyses revealed that the stress(t=-2.95, p=.006) and sleep disturbance(t=-2.13, p=.041) levels of the experimental group decreased after Dan Jeon Breathing compared to those of the control group. The difference in self-esteem(t=2.44, p=.020) level was statistically significant. From the above results, it was verified that Dan Jeon Breathing could be used as nursing intervention for hemodialysis patients to mitigate their stress, sleep disturbance and to improve their self-esteem.

In the study of divining art, Hoche(互體) plays vital roles in the composition of Goaes(卦) and interpretation of Sutras, but the reality is that the research effort for Hoche has been poor along with the perception of its utilization. This study set out to investigate connections among Bongoae(本卦), Hoche, and Hoche of Hoche(Hohoche互互體) and thus shed new light on the importance of Hoche in the composition and interpretation of Yi. 64 Goaes belong to 16 Hoches, which should belong to 4 Hoches. 4 Hoches Jungcheongeon(重天乾), Jungjigon(重地坤), Suhwagije(水火旣濟), and Hwasumije (火水未濟). That is, one can make 6 Hoikgoaes(劃卦) by extracting Hoche from the 6 Hoikgoaes comprised of Hoche of Bongoae, and they converge on 4 Goaes of Geon (乾), Gon(坤), Gije(旣濟), and Mije(未濟). The present study named Hoche of Hoche Hohoche and argued that there should be some consistent connections in the interpretation of meanings of these 4 Hohoche Goaes and their respective Hoches and Bongoaes. Focusing on the discovery of common meanings among the Hoches and Bongoaes of "Danjeon(彖傳)" and" Daesangjeon(大象傳)" of Hohoche. Book of Changes begin with Jungcheongeon and Jungjigon and end with Suhwagije and Hwasumije. The Hohoche of 64 Goaes(卦) are concluded into these 4 Goaes, which indicates that the 4 Goaes have supervision over beginning and ending and that all the Goaes between them operate within the categories of 4 Goaes. The content of "Danjeon" and "Daesangjeon" in Hohoche holds certain semantic connections in the interpretation of Hoche and Bongoae restored to Hohoche and points to the directionality of the interpretation. Those findings open a window for investigating Hoche with the core principle of Goae formation in Book of Changes and imply that Hoche holds important significance in the interpretation of the Book.
