Increasing number of consumers favor diverse nail art techniques including painting and artificial tips in addition to basic care such as cuticle trimming or coloring. Accordingly, the diversity of polish colors has been settled as a concept of total fashion in addition to the clothes and accessories. As the result, nails may be damaged or discolored. A study the nail discoloration by using polish was purposed that contribute to the development of nail protective products. The tests were conducted with 20 college students for six months from March 3 to Aug. 28, 2009, using digital camera as the measurement apparatus. The students were classified into two groups which applied bright polish (white, beige, pink series) and dark polish (purple, blue, black series), and then divided into the groups applied and not applied the base coat which is known to be effective in preventing nail discoloration, and the groups applied and not applied tonic. The students applied polish for one week, and removed the polish with remover and photographed to examine the degree of nail discoloration. Dark colored polished resulted in earlier coloration and discoloration than the bright colored ones. Base coat could prevent coloration and the color changes of hyponychium and eponychium were lighter than the cases not applied with base coat. Tonic could delay coloration and reduced the color changes of hyponychium showing that tonic was effective for preventing coloration and discoloration of nail in addition to nutrition.

The purpose of this study is to analyze check pattern of nail art from 2011 to 2013. The results of this study are as follows; 1) Check pattern of nail art is total 257 patterns, and there are 84 argyle, 29 tartan, 24 harlequin, 24 over, 23 window-pane, 15 stitcheds, 13 hound tooth, 10 block, 10 madras, 8 gingham, 8 gradation, 7 shepherd, and 2 tattersall check patterns. Through this result, in nail art, the relatively simple patterns such as a vertical pattern, a horizontal pattern, and cross or overlap diagonal line are used more than elaborate and complex check patterns of a fibrous tissue from a weaving process. 2) In check pattern of nail art, N-affiliated color and R-affiliated color are remarkably well-used, because of the effects of argyle, tartan, window-pane, harlequin, stitched, over, and hound tooth check patterns used the most during the past three years. Especially, most tartan, harlequin, over, and hound tooth check patterns use their own special colors such as R-affiliated colors and N-affiliated colors as it is, and argyle, window-pane, stitched, and over check patterns use well by arranging N-affiliated colors and R-affiliated colors. 3) The most used expressive technique is hand painting to express check pattern in nail art, because new products related to UV gel are well launched. These materials can draw fine line that is hard to express by existing polish easily and simply, and not only have set quickly hard, so procedure time is very short, so it is compatible to draw check pattern personally, but also it is well covered, so check pattern is more clearly expressed.

Objectives: The purpose of this study is to evaluate airborne concentrations of volatile organic compounds(VOCs) during nail art practice by college students. Methods: Personal samples for students were measured using passive samplers(OVM 3500) during three kinds of practice, including polish nail, gel nail and acrylic French sculpture at two universities located in Gyeongsangbuk-do Province. We also monitored area concentrations using active samplers and real-time total VOC monitors(ppbRAE 3000). All samples were analyzed with a gas chromatography flame ionized detector. Statistical analysis for monitored data were conducted using a web-based Bayesian toolkit, EXPOSTATS(www.expostats.ca). Results: Twenty-four personal samples and ten area samples were collected and five chemicals(acetone, butyl acetate, ethyl acetate, ethyl methacrylate(EMA) and methyl methacrylate(MMA)) were detected. Acetone was detected in all personal samples and ranged from 2.58 ppm to 50.3 ppm. EMA was detected in all personal and area samples with a maximum concentration of 9.78 ppm during acrylic French sculpture. Personal exposure levels to acetone, butyl acetate and mixtures were significantly higher with high occupant density (p<0.05). Geometric mean (GM) concentrations of 3.61 ppm for EMA personal samples were significantly higher than that of area samples, 1.5 ppm (p<0.05). Since there was no local ventilation, total VOC concentration continued to increase as the practice progressed. Conclusions: In order to minimize VOCs exposure for trainees, it is necessary to introduce a local ventilation system and maintain adequate occupant density.

The purpose of this study was to investigate the food sanitation awareness and performance of foodservice industry employees. Based on a literature review, a questionnaire was developed to identify the food sanitation education, experience, knowledge, and food sanitation practices of the employees. A total of 376 Korean food industry employees participated, and there were 344 usable questionnaires. In the analysis of food sanitation knowledge, the statements "clip fingernails short and do not use nail polish", and "if feeling sick, even with a minor cold, speak to your supervisor immediately", had the highest and lowest percentages of correct answers, respectively. In assessing employee sanitary management practices, many correctly acknowledged "clip fingernails short and do not use nail polish" and "wash hands after using the toilet", which received high scores; however, "use hands to pick up ice" and "if feeling sick, even with a minor cold, speak to your supervisor immediately" had low scores. The sanitary knowledge and practice levels of the employees were not significantly different according to gender, age, work area, job title, or duration of duty. Among the surveyed industries, employees of special restaurants had the least sanitary knowledge(p<0.05) and practice scores(p<0.001). Employees who had worked for $1{\sim}3$ years presented the least sanitary management practice level scores(p<0.05).). In addition, college students and participants without hygiene educational experience showed the least levels of sanitary knowledge(p<0.01). Scores for sanitary management practice were higher when hygiene education was regularly conducted more than once per month. Employees showed significantly higher knowledge and sanitary management practice levels when they were required to use a sanitary checklist(p<0.001), and employees who were trained in HACCP had significantly higher sanitary checklist scores(p<0.05). In foodservices that applied HACCP, the employees showed higher knowledge and sanitary management practice levels(p<0.001).

프탈레이트는 내분비계 교란 물질로서 성호르몬과 구조가 유사하여 주로 생식독성과 발달독성을 나타낸다. 이번 연구에서는 우리나라 화장품규제 물질인 3종 프탈레이트 이외 어린이제품 안전공통기준, EU 화장품 기준(EC No. 1223/2009) 등에서 규제하고 있는 프탈레이트 종류를 추가하여 총 11종 프탈레이트에 관하여 분석을 실시하였다. GC-MS/MS를 이용하여 분석조건을 설정하였고 분석방법에 대한 유효성 검증 결과 특이성, 직선성, 회수율, 정밀성, 정량한계 등을 만족하였다. 유효성이 검증된 시험방법을 이용하여 네일 화장품 및 네일 관련 제품 82건을 대상으로 분석을 실시하였다. 네일 폴리시에서는 DBP, BBP, DEHP, DPP, DIBP, DIDP 등 6종의 프탈레이트가 $1.0{\sim}59.8{\mu}g/g$의 농도로 검출되었으나 우리나라 화장품기준에 적합하였다. 인조손톱에서는 DIBP, DBP 2종에서 $1.1{\sim}2.6{\mu}g/g$, 글루에서 DBP, DEHP 2종 $1.4{\sim}2.5{\mu}g/g$, 스티커 DIBP, DBP, DEHP 3종에서 $2.5{\sim}33.3{\mu}g/g$ 의 결과가 나왔고 '어린이제품 공통안전기준'을 적용시 모두 적합하였다. DIBP는 우리나라에는 규제물질이 아니지만 DBP (86.6%), DEHP (63.4%)에 이어 14.6%의 검출률을 나타내었다. 현재 우리나라 기준으로는 네일제품이 프탈레이트에 대해 안전하다고 판단되지만 비규제물질에 대한 지속적인 감시와 연구도 필요할 것으로 사료된다.

Purpose: This study aimed to compare the oxygen saturation measured at fingertips with unpolished and self-artificial nails (sticker, tip) using a portable pulse oximeter. Methods: The sample comprised 27 women who had used nail care services. Using a pulse oximeter, oxygen saturation was measured at fingertips with unpolished nails in a stable state. Self-fabricated sticker and tip nails were attached to the right and left hands, respectively, using five nail colors (black, blue, green, purple, and brown). Oxygen saturation was measured at fingertips with self-fabricated nails first in the usual manner and then measured again by rotating the oximeter by 90°. Values of oxygen saturation were compared and analyzed using the Friedman test and Wilcoxon signed-rank test with Bonferroni correction using IBM SPSS 26.0. Results: Oxygen saturation values were significantly different among colors for both sticker nails (p=.036) and tip nails (p=.000), with black self-artificial nails tending to demonstrate lower oxygen saturation. Moreover, oxygen saturation values obtained by measuring the usual way on unpolished nails was significantly different than those obtained by rotating the oximeter by 90° on thumb with sticker (p=.001) and tip nails (p=.001). Conclusion: The findings of this study suggest that oxygen saturation should be measured on other fingers except for thumb instead of removing the self-artificial nails in emergency situations. For patients with black self-artificial nails, is the findings recommend measuring oxygen saturation at other body parts such as toes, earlobes, forehead, etc.
