Background: Mystery shopping is a method in which a company monitors quality of service and employee conduct and compliance with regulations using an evaluator posing as a customer. It is a typical tool of customer-centered bureaucratic control insofar as it provides overall and standardized evaluation of intangible elements of customer service as well as physical elements of service environments. The purpose of this study is to examine how mystery shopping is related to the health status of service workers in South Korea. Methods: Data from semistructured interviews with 15 workers were collected from January to April 2019 to obtain information on service worker experiences with mystery shopping. Data were analyzed using the constant comparison method. Results: Mystery shopping limits worker autonomy and stiffens the workplace environment by standardizing and monitoring labor processes for service workers. In addition, mystery shopping heightens work stress through increased labor intensity. Five mechanisms by which mystery shopping affects service worker health are identified and comprise (1) multifaceted and multilayered surveillance, (2) evaluator subjectivity and irrational requirements, (3) standardized rules combined with high pressure to achieve sales, (4) self-esteem degradation because of evaluator results, and (5) musculoskeletal disorders because of strict adherence to labor processes based on evaluator results. Conclusion: Mystery shopping as an evaluation method should be reconsidered not only in terms of health problems but also in terms of organizational efficiency and issues of human rights.

Purpose: We developed the MYSTERY CIRCLE vision training program which was suitable for Korean people. We compared it with the established programs, Block string and Anaglyphs in aspect of functional, sensory, and symptomatical changes of binocular vision. Mehtods: The vision training observation group included 75 clients (male=40, female=35) who had binocular vision disorders without opthalmic diseases or vertical phoria. Results: According to the results, all training methods showed improvement of binocular vision function, sensation and symptoms. But the Block String had low participation, reference rate of subjects and success rate and showed the different degree of improvement depending on individuals. Anaglyphs method showed high participation and improvement. But it had a low degree of success rate and preference rate. Conclusions: MYSTERY CIRCLE method showed the highest participation, reference rate of subjects, success rate, and high degree of improvement. Therefore we suggest that MYSTERY CIRCLE is an effective and alternative method for binocular vision disorder therapy.

Purpose: The purpose of this study was to investigate the effect of vision training using MYSTERY CIRCLE system on patients with exophoria and intermittent extropia. Mehtods: The vision training observation group consists of 26 clients who had exophoria (n=18) and intermittent extropia (n=8) without opthalmic diseases or vertical phoria. Our clients took each vision training once a week for eight weeks and were investigated for the symptoms changes of binocular vision. Results: According to the results, MISTERY CIRCLE vision training methods improved the binocular vision function and sensation symptoms. For Worth 4 Dot test, Titmus test and red lenses showed fusion rate changes. Conclusions: The study proved that MISTERY CIRCLE vision training system for patients with binocular vision was effective for the improvement of the binocular vision symptoms of these patients.

The objective of this study are to figure out the physical attributes of the three predictors in the Informational Approach: complexity, coherence, mystery and to investigate the relationships between these attributes and the preference exploratively. Visual inspection of the scenes relative to their rated levels of the predictors revealed the existence of relationship between these variables and the physical attributes. The following are the summary of the relationship between three predictors and the physical attributes: (1) The level of complexity was associated with the pattern of physical attributes which were the amount of facility, line, shape, color plant and arrangement of the visual elements. (2) The level of coherence was related with the regular arrangement of the visual elements. For example, there was certain pattern founded the color, shape, texture was applied to the various space repetitively and symmetrically. (3) The level of mystery had the relationship with the physical attributes of screen, spatial definition, distance of view, physical accessibility, radiant forest, the depth of space.

TV drama , aired on JTBC in 2018, used several fictional and linguistic clues on the murder case. It effectively delayed the process of inferring the perpetrator by utilizing 'ambiguity' and 'trap', which enabled the double interpretation of the the main character's diaglogue and action. This delay could be made by employment of genre hybrid, cognitive process and knowledge of viewers about typical romance plot and mystery plot in TV drama. In other words, could be evaluated as a special genre hybrid case that disturbs viewers' perception of genre in that the correct reasoning process began from the point that overturned the viewer's expectation about typical romance genre dramas in which male main characters mostly devoted to love. The complicating mystery structure shown in is against the opinion that the traditional mystery structure is difficult to succeed in TV dramas. Also, from the perspective of hybrid genre, it is different from the usual mechanical combination of two different plots. These characteristics in are worth to highly evaluated.
