  • There are various 'wireless communication technologies' around us. Wireless mobile communication has evolved through various stages, and its utilization is also diverse. However, due to the development of wireless communication technology, the demand for frequency resources is much higher than the supply, so frequency shortage is serious. Recently, 'visible light communication' has been attracting attention as an emerging communication technology that can solve the frequency shortage. 'Visible light communication' is a communication method based on serial data transmission / reception, and there is a difficulty in transmitting / receiving parallel data because the transmitter and the receiver are arbitrarily present. In this paper, we have studied parallel data processing of visible light communication. We could solve the problem by analyzing parallel data using image processing. Through this study, communication performance can be verified through I / O data comparison by implementing parallel data analysis method. It is expected that diversity in parallel data analysis will be presented through the results.

  • This study examines the psychological factors of consumers to On-Demand O2O service which is different from the previous study on O2O service. To investigate the relative influence of consumer's psychological attachment of On-Demand O2O service, enjoyment, and trust on consumer's satisfaction and attitude, I conducted qualitative and quantitative surveys to investigate consumers' perception. Through the quantitative survey on 152 participants, the study shows that the consumer's psychological attachment to the service has the greatest influence on the attitude toward On-Demand O2O service and the trust has the highest effect on satisfaction with service. This study is meaningful in that the consumer's psychological factors to the O2O service is examined from the consumer's point of view. This study suggests that the consumer's attachment and trust should be considered primarily to expand the On-Demand O2O service.

  • The purpose of study is to investigate the effect of life stress on university life satisfaction and majors' From April 2, 2018 to April 23, 2018, 364 students enrolled in Jeollanam-do and Gwangju were enrolled. The university life satisfaction and major satisfaction according to the general characteristics were the highest in the subjective health condition. Among the stresses of life, the professions were high in the interpersonal relations area and the academic problems were the highest among the task areas. The total stress of life was the lowest in 6-8 hours in the case of usual sleeping time. The major factor influencing college life satisfaction was majors' satisfaction. The major factor influencing major satisfaction was college life satisfaction, and the higher the life stress, the lower the satisfaction of major. Therefore, I would like to use this data as basic data for the development of programs that can alleviate life stress of University students.

  • Objectives: The aim of this study was to evaluate the influence of different concentrations of nanofillers on the chemical and physical properties of ethanol-solvated and non-solvated dental adhesives. Materials and Methods: Eight experimental adhesives were prepared with different nanofiller concentrations (0, 1, 2, and 4 wt%) and 2 solvent concentrations (0% and 10% ethanol). Several properties of the experimental adhesives were evaluated, such as water sorption and solubility (n = 5, 20 seconds light activation), real-time degree of conversion (DC; n = 3, 20 and 40 seconds light activation), and stability of cohesive strength at 6 months (CS; n = 20, 20 seconds light activation) using the microtensile test. A light-emitting diode (Bluephase 20i, Ivoclar Vivadent) with an average light emittance of $1,200mW/cm^2$ was used. Results: The presence of solvent reduced the DC after 20 seconds of curing, but increased the final DC, water sorption, and solubility of the adhesives. Storage in water reduced the strength of the adhesives. The addition of 1 wt% and 2 wt% nanofillers increased the polymerization rate of the adhesives. Conclusions: The presence of nanofillers and ethanol improved the final DC, although the DC of the solvated adhesives at 20 seconds was lower than that of the non-solvated adhesives. The presence of ethanol reduced the strength of the adhesives and increased their water sorption and solubility. However, nanofillers did not affect the water sorption and strength of the tested adhesives.

  • The purpose of this study is to compare a supposedly "pot boiler", Sanctuary and Sanctuary: The Original Text and examine the fact that Horace Benbow in The Original Text is a more complicated and many-sided character who has suppressed desire, Oedipus complex, sense of guilt for a long time, until he came to confront Temple-Popeye case. Since literary narration means unconscious procedure, Horace's incestuous love for his step daughter and Oedipal relation reveals Faulkner's own psychology. In this sense, The Original Text serves as a matrix of many of Faulkner's major novels in terms of themes, characters, and the relationship between past and present. Among these novels are The Sound and the Fury, As I Lay Dying, and Flags in the Dust. Faulkner, while writing about his own world creating Yoknapatawpha County, tries to portray characters with artistic value through whom he wanted to express the deep anxiety and turmoil of the 1920s. Starting with Horace Benbow, Quentin Compson, Darl Bundren and young Bayard Sartoris can be doubling through his major works, conveying author's profound despair in the context of modern world.

  • The purpose of this descriptive research was to investigate importance awareness on peripheral intravenous infusion, and to identify the factors influencing on importance awareness among 128 children's hospital nurses. The collected data were analyzed with descriptive statistics, T-test, ANOVA, Pearson's correlation analysis and Hierarchical multiple regression using SPSS 21.0. Importance awareness on peripheral intravenous infusion of children's hospital nurses was the lowest in education, and the highest in hand hygiene. There were significant differences in subdomains of peripheral intravenous infusion according to marriage state, working department, position and final education(p<.001~.046), and there were positive correlations between education and importance awareness of peripheral intravenous infusion(p<.001). And factors affecting importance awareness were education(${\beta}=.446$) and working department(${\beta}=.247$), and explannation rate was 31.0%(p<.001). These results could be used as basic data of educational program on peripheral intravenous infusion for children's hospital nurses after repeated study.

  • The purpose of this study was to analyze the moderating effects of teacher support on the effects of acculturation stress on school adjustment of multicultural adolescents. To this end, we used the 6th Year (2016) adolescents survey data of 1,329 multicultural adolescents from the Multicultural Adolescents Panel Survey(MAPS), which was constructed by the National Youth Policy Institute(NYPI). Using SPSS 22.0, frequency analysis, descriptive statistical analysis, and moderated multiple regression analysis were used as dependent variables for school adjustment of multicultural adolescents, as independent variables for school adjustment, and as moderating variables for teacher support. As a result, first, multicultural adolescents experienced acculturation stress, and school adjustment decreased as the acculturation stress increased. Second, teacher support was found to have a statistically significant moderating effect on the effects of acculturation stress on school adjustment of multicultural adolescents. Based on the results of this research, I discussed and suggested the supportive measures, the role of teachers, and follow-up research to reduce the acculturation stress of multicultural adolescents and increase the level of school adjustment.

  • Turbulence is one of the natural phenomena in molecular clouds. It affects gas density and velocity fluctuation within the molecular clouds and controls the mode and tempo of star formation. However, despite many years of study, the properties of turbulence remain poorly understood. As part of the Taeduk Radio Astronomy Observatory (TRAO) Key Science Program (KSP), "mapping Turbulent properties In star-forming MolEcular clouds down to the Sonic scale (TIMES; PI: Jeong-Eun Lee)", we have fully mapped two star-forming molecular clouds, the Orion A and the Ophiuchus molecular clouds, in 3 sets of lines ($^{13}CO$ J=1-0, $C^{18}O$ J=1-0, HCN J=1-0, $HCO^+$ J=1-0, CS J=2-1, and $N_2H^+$ J=1-0) using the TRAO 14-m telescope. We apply a statistical analysis, Principal Component Analysis (PCA), which can recover an underlying turbulent-power spectrum from an observed P-P-V spectral map. We compare turbulence properties not only between the two clouds, but also between different parts within each cloud. We present the first result of our observation program.
