Background: This study aims to investigate the perception and actual situation of online classes of college physical therapy students after COVID-19. In addition, it is necessary to conduct a fact-finding survey on how physical therapy students who have experienced online classes think about the online class method, what are the overall problems, and to what extent they are satisfied. Methods: The subjects of this study were 102 students in the 3rd year of physical therapy at University A, and the survey period was from June 10 to June 23, 2020, and the perception and use of online classes and self-regulated learning ability were investigated. Design: Cross-section study. Results: The perception of online lectures, it was found that the perception of online classes after actual online classes was better than the perceptions before watching (utilization), and satisfaction with online classes was generally high. There was a significant difference according to the grades in self regulated learning. The data values measured in this study were analyzed using SPSS (Statistical Package for Social Science) Windows version 12.0 statistical program. Conclusion: These results suggest that in future research, it is necessary to study the perceptions and actual conditions of each class compared to online classes and face-to-face classes.

This paper aimed at examining the influence of L1 (native language) phonology when speakers of L1 perceive L2 (foreign language) sounds. Korean and Japanese learners of English took a perception test of Australian English words 'work', 'walk' and 'wok'. Based on Korean and Japanese phonology, it was predicted that Korean subjects would face more difficulties than Japanese subjects. The results of the experiment substantiated the influence of L1 phonology in L2 learners' L2 sound perception.

The purpose of this study is to investigate the perception on video material making and the effect on science teaching ability after conducting non-face-to-face teaching material making activity for elementary pre-service teachers. This activity consisted two processes. One is that elementary pre-service teachers conduct inquiry, understand related science concepts, analyze science textbooks and then make video material. The other is that they watch video materials produced by colleagues. This study was conducted on 89 elementary pre-service teachers for 8 weeks. After this activity was completed, the perception on video material making and the effect on science teaching ability of elementary pre-service teachers were investigated, and the results were analyzed. In the process of making and watching non-face-to-face teaching materials, elementary pre-service teachers showed positive results in teaching-learning, video production, and emotion and attitude toward video material making. In addition, it was found that they improved their science teaching ability through this activity and were very satisfied with this activity. However, they also mentioned several disappointments such as exclusion of learners' right to self-determination, lack of various communication channels, and errors in content of materials. This suggests that if these problems are solved, non-face-to-face classes can also be a good form of class.

Daily science classes, which have been continued as part of the spread of participatory science culture, has taken the lead in popularizing science as an effective out-of-school experiential and research activity. However, due to the recent COVID-19 situation, daily science classes have also become an environment in which there is no choice but to switch to non-face-to-face or to combine face-to-face and non-face-to-face education. Therefore, in this study, we examine how elementary school students participating in the non-face-to-face daily science class program change their usual fields of interest, perception of science and technology, interest about science, and scientific competency. In addition, the educational effectiveness of the non-face-to-face daily science class improved by comparing the differences in perceptions of students and parents, and future operation plans were sought. As a result of the study, after participating in the non-face-to-face daily science class program, students' interest in science and technology development, future technology, environmental pollution, and social media increased, and their interest in games decreased. Also, students' interest in science and technology activities, interest in science, and scientific competency also increased. This shows that non-face-to-face daily science class education is effective. Therefore, it was suggested that it is necessary to diversify the learning topics and content levels of the daily science class program, to expand the opportunities of non-face-to-face science education for underprivileged learners, and to develop and share science content using the latest media.

Purpose: The purpose of this study was to explore dimensions to improve airline non-face-to-face(untact) service quality and identify shadow work dimensions in the digital environment among them. Methods: This study conducted mixed method. First of all, For finding out the dimensions of airline untact service quality, in-depth interviews were conducted from passengers. The collected data through the survey were analyzed using improved importance-performance analysis(IPA). Second, An online survey was conducted to quantitatively analyze user perception about airline untact service quality, and the importance performance of service quality at each dimension was identified through the revised IPA method. Results: The results of this study are as follows; Through in-depth interviews, 11 dimensions found out and 32 measurement items were developed. and then, through the revised IPA analysis, passengers were highly satisfied with "Cleanliness of in-flight service" and "Reliability of self check-in". Also, We found 3 shadow work dimensions such as "Ease of use of self check-in", "Usefulness of self check-in", and "Responsiveness of self check-in". Conclusion: Airline service providers have to keep high-satisfaction services and urgently improve less satisfied services. In particular, the dimensions related to shadow work have to be improved.

Objective: Improvements in diet can decrease the cancer rates. The aim of the present study was to determine the relationships between self-perception of diet quality and personality, impulsiveness, stress, coping strategy, sense of coherence, self-efficacy, and social support. Methods: This cross-sectional study was conducted using a multiple-stratified random sampling method based on the Korea Census of 2007. In October 2009, investigators conducted 15-minute face-to-face interviews with 1,530 South Korean volunteers who ranged from 30 to 69 years of age without a history of cancer. Results: Respondents were more likely to perceive that they consumed a healthy diet if they were older than 50 years, lived with a partner, had a monthly family income greater than $4,000 USD, had a low perceived risk of cancer, consumed less alcohol, exercised regularly, had a less agreeable or conscientious personality, had low stress levels, had a high sense of coherence or self-efficacy, and had ample social support. Conclusion: Psychosocial factors, such as personality, stress, sense of coherence, self-efficacy, and social support, are associated with the self-perception of diet quality. Analysis of the factors that contribute to a perceived healthy diet could assist with the design of educational campaigns.

The purpose of this study was to investigate the perception of dental students based on their experiences of online classes after taking non-face-to-face education courses for all the school semesters in 2020. For the research method, an online survey was conducted on A survey was conducted on 161 dental students enrolled in A University. The analytical method was conducted through frequency analysis, correlation analysis, and multiple regression analysis. The survey analysis findings showed that the satisfaction of dental students' about the non-face-to-face education course was above 4.2, and the detailed items were in the order of the appropriateness of the attendance processing method, satisfaction with recorded video lectures, and the assessment method of the course grade. In the case of the factors that affect the satisfaction of non-face-to-face education courses, the learning system and assessment method were statistically significant. The online class type that is most preferred by the students is recorded video lectures, and the highest number of participants chose 21~30 minutes as the appropriate time for the class content. It is considered that the application of the online system will continue to be used together with face-to-face education courses in the education site and various university-level efforts like systematic support are required to achieve effective learning achievements. This study only investigated the non-face-to-face education operation conditions of A University, so it cannot be generalized to all universities, but it can be used as basic data to provide education curriculum design and supportive measures for the compatibility of face-to-face and non-face-to-face courses.

Objectives: In chemical hazard communication, information receiver's perception is a important factor, but the study on the perception was few. Therefore, this study evaluated the perception of managers and workers group about chemical hazard communication by chemical hazard communication tools that were being used in fields. Methods: 91 managers and 238 workers were surveyed in two companies where use chemicals. All subjects were asked about the comprehensibility and perception for MSDS and GHS Pictograms being used in their workplaces through face-to-face interviews. Results: Most of the respondents knew MSDS, and more than half of the respondents had used MSDS once or more per year. The level of use to find the information on chemicals with MSDS was higher in the managers in comparison with workers. Also, the managers could understand and find the information on MSDS easier(p < 0.05). In the question asking the meaning of GHS Pictograms, the managers responded more correctly, as well(p < 0.05). 86.8% of the managers and 62.6% of the workers were conscious of the possible health hazards of chemicals that they could be exposed at work. However, among the respondents conscious of the health hazards, only less than 70% were well aware of the contents of the health hazards correctly. Conclusions: In chemical hazard communication, it is very important to evaluate whether information receiver have proper and correct knowledge and perception or not and actions based on the evaluations as well as provide correct information.

Background : The Current Perception Threshold (CPT) provides an objective, quantitative gauge of sensory nerve integrity which is obtainable from any cutaneous site. CPT measurement can confirm and quantify or rule out dysfunction of nerve through comparison with established normative values ($Neuval^{TM}$ CPT database). The aim of this study is to compare collected data from Korean adults with $Neuval^{TM}$ CPT database. Method : Normative data from 5 standard test site in face, hand, toe were obtained from 50 healthy adults. Three frequencies(5, 250, 2000 Hz) were stimulated with $Neuromoter^{(R)}$ CPT device. Results : The results of our data were statistically significantly different than Neuval data except in face, but within normal range. Sensory Threshold increased as the frequency of the stimulus changed from 5 Hz to 250 Hz to 2000 Hz., and from face to hand to toe. Conclusion : CPT testing is a valuable neurologic testing modality that is noninvasive and highly reliable for diagnosis and evaluation of sensory nerves where neuropathy is suspected.

The purpose of the study is to make experimental whether three-dimensional body (especially face) has illusion based on theoretical background of form dimensions and color bright among precedent multi-form illusion, using the function of computer simulation. To investigate illusion that factors of clothing design(line, color, material) effect face, as the following is tried to solve giving change to neckline, collar, scarf which is believed to influence near face. How to make experiment as follows watching in order 13 scenes of a pair of with basic design and experiment design. Then the data were subjected to analysis of variance and Duncan's multiple range test. The result of this studying as follows, 1. Face looks larger in complex neckline than simple neckline. The larger collar is the larger face looks. 2. In white jacket, illusion(the lower luminosity of scarf color gets, the brighter face brightness gets) is shown. In black jacket, also illusion(the higher luminosity of scarf color gets, the darker face brightness gets) is shown. 3. In experiment on hardness and softness of face impression according to the material of collar, collar of knit and fur gives us assimilation illusion bring softer impression of face.
