Objective: The aim of this study is to investigate and review the previous researches about objective measuring fatigue caused by visual stimuli. Also, we analyze possibility of alternative visual fatigue measurement methods using facial expression recognition and gesture recognition. Background: In most previous researches, visual fatigue is commonly measured by survey or interview based subjective method. However, the subjective evaluation methods can be affected by individual feeling's variation or other kinds of stimuli. To solve these problems, signal and image processing based visual fatigue measurement methods have been widely researched. Method: To analyze the signal and image processing based methods, we categorized previous works into three groups such as bio-signal, brainwave, and eye image based methods. Also, the possibility of adopting facial expression or gesture recognition to measure visual fatigue is analyzed. Results: Bio-signal and brainwave based methods have problems because they can be degraded by not only visual stimuli but also the other kinds of external stimuli caused by other sense organs. In eye image based methods, using only single feature such as blink frequency or pupil size also has problem because the single feature can be easily degraded by other kinds of emotions. Conclusion: Multi-modal measurement method is required by fusing several features which are extracted from the bio-signal and image. Also, alternative method using facial expression or gesture recognition can be considered. Application: The objective visual fatigue measurement method can be applied into the fields of quantitative and comparative measurement of visual fatigue of next generation display devices in terms of human factor.

This survey is to compare the handwashing recognition and practice of middle school students in Korea and Nepal, according to the report that handwashing practice rate of Korea was significantly lower than those of developed countries. The handwashing survey tools of Korean CDC were used. As a result of analyzing data using SPSS/Win 23.0, there were differences in residential state, disease experience, and parental education level of subjects, handwashing practice was significantly higher in Nepal while higher handwashing recognition of Korea(p<.001). Among contents of handwashing practice, there were significant differences in drying methods, number of it with soap, time required, number of receiving education for it, and education methods. It is necessary to take measures to increase handwashing practice rate of Korea, while Nepal's is increasing by supplementing equipment and education even their handwashing recognition was low. This results are from a few middle school students in both countries by convenience sampling, therefore it is needed repeated studies with wider range of subjects.

This study aimed to investigate recognition of dental scaling and recognition of and satisfaction with health insurance coverage of dental scaling and make an efficient healthcare policy for dental health insurance; to do this, a survey was conducted in 389 residents in North Jeolla Province, drawing the following conclusion: First, the respondents were most likely to suggest that it was desirable to get dental scaling 'twice a year' and to start it 'in their twenties'. Second, those who were female and who were more concerned about periodontal health were more likely to recognize coverage of dental scaling. Third, those who were female and who were more concerned about periodontal health were also more satisfied with the coverage. It is therefore necessary to make PRs by using teaching media positively as well as by giving correct information with the objective of improving recognition of dental scaling on a continuous basis.

BACKGROUND: The present study is an exploratory research to establish national biosafety regulation systems through a survey on the recognition of safety regulation systems for the living modified organism(LMO). METHODS AND RESULTS: We have conducted a survey on an awareness of LMO safety regulation systems in scientific working groups. The data of 235 respondents were analyzed using various statistical methods. As a result, 72.8% of the respondents were male; 27.2% were female, and 43.4% of them work in the university. A total of 33.2% of the respondents majored in general biology, and their most common job position was the laboratory safety manager. The difference of an awareness on LMO law and regulatory system was not statistically significant by either work places or job positions. CONCLUSION: For the rapid settlement and the efficient implementation of LMO safety management policy, we conclude that it is required to reduce the gap between the recognition and fulfillment of safety management. Furthermore, the mutual exchanges of information among researchers are needed with the settlement of the safety management system and the harmony of policy with improvement of the absurd regulations. The ongoing and specialized training, inspections, and the strengthening of public relations are also required along with the efforts to improve the absurd regulations.
