This study aims to examine the effect of discrimination experience on job satisfaction among working women with disabilities, focusing on meditating effect of self-esteem. To this end, the data from the 8th year of the employment panel of disabled population surveyed by the EDI; Korea Employment Agency for the Disabled was used for the study. The data collected from 549 working women of disabilities from EDI was analysed by using the path analysis. The findings are as follows: first, discrimination experience of working women with disabilities had a significantly negative effect of their job satisfaction. Second, self-esteem presented the mediating effect between discrimination experience and job satisfaction. Based on the results, this study proposed various programs to increase job satisfaction by enhancing self-esteem in situations where the experience of discrimination among women with disabilities is high and suggested practical implications to increase job satisfaction of working women with disabilities.

This study was performed to examine the effect of convergence-based simulation education on the problem solving ability and self-efficacy and confidence of core fundamental nursing skill performance for nursing students. A non equivalent control group post-test only design was utilized(experimental group(n=97), control group (n=87)). Data were analyzed using independent t-test, Chi-square test and Pearson's correlation. The scores of the problem solving ability(t=-2.04, p=.043) and confidence of core fundamental nursing skill performance(t=5.31, p<.001) were higher than those of the experimental group than control group. It is necessary to find ways to iterative and convergent research that verifies the continuous development and effectiveness of various courses.

Due to the dramatic improvement of Internet technologies and digital content authoring, many independent media creators produce various digital items and share them with others. In this situation, the independent media platforms must support the well-defined usage rights(licenses) specification, usage monitoring, and license trading trace for enabling complex types for selling, buying, using and reproducing digital items created by independent media creators. In this paper, we design an extended policy model based on the ODRL policy class model and implement a user interface prototype to specify multi types of usage rights like use, own, share, and cede. Our proposed model can be referenced to create license management modules of the independent media platforms.

This study was conducted to examine the correlations between humanistic literacy, empathy ability, and interpersonal relationship, and to identify the influencing factors on interpersonal relationship of nursing students. Data were collected from 177 nursing students from March 4 to 14, 2019. Data were collected through personal interviews using a questionnaire. Data were analyzed using t-test, one-way ANOVA, Pearson's correlation coefficients, and stepwise multiple regression. Humanistic literacy according to the general characteristics showed significant differences in economic level. Interpersonal relationship according to the general characteristics showed significant differences in satisfaction with major. Interpersonal relationship showed significant positive correlations with humanistic literacy and empathy ability. Empathy ability, which accounted for 21% of the variance, were significant predictors influencing interpersonal relationship in nursing students. Strategies for nursing students are needed to increase Empathy ability.

The purpose of this study is to compare students' perception shaped by two different university classrooms: Traditional Classroom and ALC(Active learning classroom). We conducted survey of 71 university students who were taught by an identical instructor using same pedagogy. The survey questionnaires asked respondents about their perceptions on teaching and learning and physical environments relations, teaching proficiency, social context, student satisfaction and immersion. The data was analyzed using Student's T-test. The results showed that ALC group, compared to the traditional classroom group, demonstrated statistically higher awareness on teaching and learning and physical environments relations, teaching proficiency, and instructor-student unofficial relations. Based on these findings, implications and limitations of this study were discussed.

Chemical terrorism and accidents using chemicals are continuously occurring and attempted in and out of the country. In Korea, the National Institute of Chemical Safety affiliated with Ministry of Environment employs the CARIS(Ver. 2018) to assess the damage impact range for field-based response against chemical terrorism and accidents. However, the current version of CARIS can not consider the effects of closed space such as indoor and underground, so it is difficult to provide accurate evaluation results for damage impact range required for field response, on top of the limited information available. The limitations and directions for improvement were studied by comparing and reviewing the evaluation results of the damage impact range obtained by driving CARIS (Ver. 2018) and the domestic and foreign literature. Proposed improvements also included the direction of information provided to residents, including the need to build modeling for special points, such as underground, indoor, etc., and on-site response personnel. It is expected that through the continuous supplementation and correction of CARIS, chemical terrorism and accident response capability system will be advanced further.

This study examined the effects of rapid thermal annealing (RTA) on the physical and chemical characteristics of thin silver (Ag) layers on SiO2 coated metal foils. Ag layers were annealed at various temperatures of the range between 150 ℃ and 550 ℃ for 20 min. The surface roughness and resistivity are increased at the annealing temperatures of 550 ℃. We also found that oxygen (O) and silicon (Si) atoms exist at the Ag film surface by using compositional analysis in the annealing temperatures of 550 ℃. The total reflectance is decreased with increasing temperature. These phenomena are due to an out-diffusion of Si atoms from SiO2 layers during the RTA annealing. The results offer the possibility of using it as a substrate for various flexible optoelectronic devices.

In the fifth generation (5G) mobile networks, the mobile services require 100 times faster connections. One of the promising 5G technologies is non-orthogonal multiple access (NOMA). In NOMA, the users share the channel resources, so that the more users can be served simultaneously. There are several advantages offered by NOMA, such as higher spectrum efficiency and low transmission latency, compared to orthogonal multiple access (OMA), which is usually used in the fourth generation (4G) mobile networks, for example, long term evolution (LTE). In this paper, we compare the receivers for NOMA. The standard NOMA receiver, the non-SIC NOMA receiver, and the symmetric superposition coding (SC) NOMA receiver are compared. Specifically, it is shown that the performance of the standard receiver is the best, whereas the performances of the non-SIC receiver and symmetric SC receiver are dependent on the power allocation.

This study tries to examine the effect of positive and negative parents' attitudes on adolescents' smartphone dependency, and prove the meditating effect of poor attachment between the two variables in the times of convergence. For the study, the data from the Korean Children and Youth Panel Survey were analyzed by utilizing the path analysis, the data from 1,971. The results are as follows: First, positive and negative parents' attitudes influenced adolescents' poor attachment. Second, positive and negative parents' attitudes had a effect on adolescents' smartphone dependency. Third, parents' attttudes directly influenced adolescents' smart phone dependency and its' effect was indirectly mediated by the subjects's poor attachment.
