Background: To identify work-family balance and level of happiness among married women dental hygienists in Seoul and Gyeonggi Province. The goal of this study is to use the outcome as basic data to determine the compatibility of dental hygienists with work and family, systems, and improvement of happiness levels. Methods: From July 3 to August 10, 2020, 250 dental hygienists in Seoul and Gyeonggi Province were targeted. The questionnaire comprised 65 questions, including general characteristics (perception of work-family balance, perception of work-family balance system, job satisfaction, parenting type, happiness level) whether or not they were implemented. The results were obtained through a self-control questionnaire. Results: The perception of work-family balance was significantly different in job rank and average income, while that of the work-family balance system had significant differences in workplace type, total work experience, current job work experience, childcare system status, and parental leave period. Happiness level and job satisfaction were significantly different in job rank, average income, and childcare system status. Additionally, the perception of work-family balance and that of the work-family balance system showed a positive correlation with job satisfaction and happiness level. Finally, the perception of married women dental hygienists toward work-family compatibility was determined, where the higher the satisfaction with the job, the higher the level of happiness. Conclusion: To improve the work-family balance and job satisfaction of dental hygienists and their levels of happiness, changes in social perception and improvement of the working environment such as proper staffing, flexible work systems, and incentive systems should be considered.

This study conducted a subjective evaluation of brightness perception and visual discomfort according to dimming speeds and CCTs(Correlated Color Temperatures). Dimming speeds of two different CCT lights(2,700K, 6400K) were set to 1.7%/s, 3.3%/s, 5.0%/s, 6.7%/s, and 10.0%/s respectively. Subjects checked the time when they perceived the change of the brightness and visual discomfort. As a result, when dimming speeds were 1.7%/s, 3.3%/s, 5.0%/s, 6.7%/s, more than half of subjects responded the change of the brightness in 55.0~45.0% dimming ratios, and felt the visual discomfort in 35~25% dimming ratios. When the brightness was changed, dimming level responded to the brightness perception of hight CCT(6,400K) was higher about 8.0% then dimming level responded to the brightness perception of low CCT(2,700K). Dimming level responded to the visual discomfort of low CCT(2,700K) was higher about 5.0% then dimming level responded to the visual discomfort of hight CCT(6,400K).

A survey of risk perception in South Korea was conducted in 2007 to evaluate relative riskiness of typical industrial and technological risks. This article summarizes the characteristics of risk perception using psychometric analyses. The survey with a sample size of 1,194 reviews the perceived level of 25 risk items in the areas of transportation, chemicals, environment, industry, nuclear power generation, and newly-introduced risks. Six categories of risk identified by a factor analysis show that the level of perceived risk does not correspond to the statistical level. Psychometric analyses including voluntariness, severity, effect manifestation, exposure pattern, controllability, familiarity, benefit and necessity demonstrate that voluntary, familiar and immediate risks are perceived as less risky than involuntary, unfamiliar and delayed ones. Risk communication is critical in reducing the discrepance between objective and subjective level of risk. However, the amount of risk information does not always justify a successful risk communication. A safety policy, risk communication strategy in particular, should take into account diverse dimensions of risk reviewed by psychometric analyses in the study. Social policy toward safety can be improved by integrating policy, human, and social factors as well as technological advances.

The purpose of the study was to evaluate the perception of importance about HACCP guidelines of dietitians. A questionnaire was developed to achieve research objectives and sent to random samples of 500 dietitians by a mail ; 418(84%) responses were analyzed. The respondents used three-point-scale to rate their perception of importance about HACCP from 1-"will be necessary" to 3-"very important". All statistical analyses were conducted using SAS package(version 8.12) for Windows. Means and standard deviations were computed for all variables. One-way analysis of variance and Duncan's multiple range test were used to assess differences in the perception of importance about HACCP guidelines among business and industry, health care and school foodservice managers. The study results were summarized as follows. Dietitians especially had lower perception of importance on the contents of Critical Control Points(CCPs), such as; adequate thawing methods and keeping records(1.95) and correct cleaning and sterilizing for raw vegetables and fruits(1.93). The rates of perception of importance about HACCP guidelines were significantly different from 19 of the 37 contents among business and industry, health care and school foodservice(p<.05 or p<.01 or p<.001). Generally, the item related to purchasing and inspection management had the highest perception level score and the item related to pre-preparation management had the lowest perception level score in foodservice production process(p<.001). Results indicate that there is a need for increased education of dietitians about HACCP principles and appropriate practices.

Objective: The purpose of this study is to identify visual perception of and satisfaction with the orange peel effect of surface. The orange peel effect is a type of finish on painted or coated surface. Background: Gloss paint sprayed on a smooth surface (such as car body, smart phone, and electric home appliances, etc.) should also dry into a smooth surface. Then, a surface resembling the texture of an orange peel can be caused by some factors. The orange peel effect can degrade user's satisfaction with a product. Method: Visual perception and emotional satisfaction were subjectively evaluated using Likert scale. The significance of orange peel effect on visual perception and satisfaction were then analyzed by the analysis of variance. The correlation between visual perception and satisfaction was also analyzed. Results: Surface roughness significantly influenced visual perception and emotional satisfaction. The level of visual perception increased and emotional satisfaction decreased with the increase of orange peel effect. Emotional satisfaction decreased with the increase of visual perception level. Conclusion: It was identified that orange peel phenomenon on surface was a very important factor for emotional satisfaction. The orange peel effect on the surface of a product should be minimized to improve the emotional satisfaction of the product. Application: The result of this study can be applied to the texture design of the body of a car, smart phones, and electric home appliances, etc.

This study investigates how perception of easy sentences varies with prosody pattern, sound intensity, and signal-to-noise ratio(SNR) in young adults with normal hearing who were in their 20's. The results showed that the presence of proper prosody pattern in the sentences increased correct perception rate of the target sentences, and that the lower the intensity and SNR, the lower the sentence perception scores. The results also showed that SNR had a greater effect on the sentence perception scores than sound intensity. There was a significant decrease of perception scores starting at the level of 15 dB and +3 SNR for the sentences with prosody pattern, while starting at the level of 18 dB and +6 SNR for the sentences without prosody pattern, ending up with a very poor perception score as sound intensity and SNR gets lower. There was a significant difference in the perception score of the sentences with prosody pattern between 20 year-old group and 21 year or older group in several listening conditions of sound intensity and SNR.
