In this paper, we analyzed audience satisfaction procedures in performing art, specifically in musical, in terms of Expectation Disconfirmation Theory. We analyzed one's expectations and outcomes over time; we first classified audience expectations and outcomes about environmental elements as 'the first expectation'/'the first outcome' and about watching situation & content itself as 'the second expectation'/'the second outcome', then analyzed by comparing those two. Through surveying and analyzing the result, this paper serves that the ultimate fact which affects on the final audience satisfaction is 'the second outcome', which is the outcome about watching situation & content itself. This paper also shows that audience expectation toward physical quality of environment affects to 'the second expectation', then 'the second expectation' affects to 'the second outcome', so then affects to the final satisfaction.However, 'the first outcome' doesn't affect to 'the second expectation'; in other words, the physical environment does not affect much to the audience final satisfaction. We expect that our study provides clues for venue management in performing arts.■ keyword :|Expectation Disconfirmation Theory|Performing Arts|Service Quality|Satisfaction|
To enhance color purity and operational lifetime of displays, thermally activated delayed fluorescence (TADF) materials for organic light-emitting diodes (OLEDs) have been intensively investigated. The key to success is a combination of a TADFbased high bond dissociation energy (BDE) material as an assistant and a fluorescence-based narrow FWHM material as an emitter. In this work, we report the R/G/B hyperfluorescence (HF)-OLED which can emit high color purity with long operational lifetime (LT95). The optimized R/G-HF-OLEDs exhibited the LT95 of 230 hrs and 300 hrs with full width at half maximum (FWHM) of 42 and 34 nm at 12.7 and 50 mA/cm 2 , respectively. Furthermore, B-HF-OLED reached the FWHM of 20 nm, External quantum efficiency of 20% and the LT95 of 300 hrs, which has more than doubled in efficiency of monochromic color, and nearly half in lifetime compared with B-F-OLED LT95 of 650 hrs at 300 nits.
The purpose of this study was to investigate the educational factors on career choice of science-gifted students to science and technology bound universities and the difference of perception in regards to group factors. In addition, this study aimed to examine the effects of science-gifted education and critical events in relation to career choice to science and technology bound universities. For the study, 104 university freshmen, 75 males and 29 females, were sampled from UNIST (Ulsan National Institute of Science and Technology), that many science high school graduates entered this year. The survey was conducted with questionnaires to do with the perceptions concerning career choice and educational factors that cause them to choose such career directions. The educational factors on career choice to science and technology bound universities were classified as 3 main categories such as educational environment factor (teaching-learning factor), human factor, attitude towards science factor and the subcategories within each category. The research findings are as follows: First, the factors were closely connected with each other and 'the project centered classes' were highly interrelated with other educational environment factors such as 'the experiment activity and environment for the activity' and 'influence of teachers (professors).' Second, the female students and graduates of the science high school were more positively influenced by the educational environment and human factors on their decision for career than male students and graduates of the general high school. Third, this research found that historical scientific knowledge, perception of scientists' social status and job applications in the science field gave less influence rather than other factors on their decision for career. As a result of examining critical events for science-gifted education in relation to career choice to science and technology bound universities, numerous students mentioned that the extracurricular science activities such as science camps and field trips gave significant effects on students' career choices to science and engineering fields.
The purpose of this study is to secure a social safety net such as the prevention of loneliness by targeting the elderly and single households for the vulnerable class in this study. In this regard, elements that are essential in basic life were defined as life-responsive information, and methods for data collection and linkage with the welfare system were sought. Life responsive data was defined as indoor motion detection and door open detection sensors based on the energy consumption data required by home appliances used on a daily basis. In addition, public data such as electric power companies were linked in order to link with the energy welfare system. As a result, various life-response information was collected according to the characteristics of each household, and the characteristics of an elderly single household were derived. In the future, in order to secure energy welfare and social safety net at the same time, it is thought that it will be possible to collect data accumulated over the four seasons and use it to secure a safety net for the elderly.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
