Purpose: An ingrown nail is common in military trainees who are exposed to highly demanding activities. Although the matrixectomy procedure has been the main treatment modality, several drawbacks may follow after the procedure, such as infection, periostitis, and continued pain that causes a delayed return to duty. This study examined the outcomes of a simple partial nail extraction with the hypothesis that this procedure may bring an earlier return to duty, lower the perioperative complications, and produce a comparable recurrence rate. Materials and Methods: The medical records of patients who had surgical treatment for an ingrown nail in the authors' institution between April 2016 and December 2017 were reviewed retrospectively. Under the inclusion and exclusion criteria, 28 patients with a simple partial nail extraction (group A) and 29 patients with a partial nail extraction with matrixectomy (group B) were investigated. As the clinical outcome, the visual analogue scale (VAS) and satisfaction score, time to return to duty, complications, and recurrence rate were checked and compared between the groups. Results: The VAS scores of group B were significantly higher during the first (p<0.001) and second (p=0.026) follow-up week than group A. The time to return to duty was shorter in group A (7.8 days) than group B (10.1 days), and this difference was significant (p<0.001). Group B had five patients with complications, whereas group A had none (p=0.028). No differences in the recurrence rate (p=0.197) and patient satisfaction (p=0.764) were found between the groups. Conclusion: In this study, simple partial nail extraction in military trainees resulted in lower postoperative pain, lower complication rates, and earlier return to duty than the procedure with matrixectomy. Military trainees are temporarily exposed to highly demanding activities. Thus, a satisfactory outcome would be expected with simple partial nail extraction without performing a radical procedure, such as a matrixectomy.

Objectives: The purpose of this study was to investigate nail hygiene behaviors and to identify the relationship between hand hygiene beliefs and nail hygiene behaviors among dental hygienists, dental's aide and dental coordinator in South Korea. Methods: The subjects were 291 dental workers including dental hygienists, dental assistant and dental coordinator working full-time at dental clinics, dental hospitals, general dental hospitals and dental university hospitals in Seoul, Incheon, and Gyeonggi-do. The questionnaire consisted of a total 35 items, including 4 items on general characteristics, 25 items on hand hygiene, 2 items on "nail art" experience, and 4 items on nail hygiene behaviors. The collected data were analyzed using an independent t-test, one-way ANOVA, chi-square test, correlation analysis, and multiple linear regression analysis, where ${\alpha}<0.05$ was considered statistically significant. Results: The scores of behavioral beliefs, normative beliefs, control beliefs and nail hygiene behaviors were $5.15{\pm}0.58$, $5.26{\pm}0.81$, $3.69{\pm}0.96$ and $5.03{\pm}0.98$, respectively. Statistically significant relationships were detected in terms of participants' clinical experiences with respect to behavioral and normative beliefs (p<0.05 for all three belief categories). Participants working in general dental hospitals and dental university hospitals demonstrated the highest scores for behavioral, normative and control beliefs (p<0.05). Participants working in dental clinics reported the highest "nail art" experience rates in the last two years (45.5%) and at the time of the survey (15.7%; p<0.05). Nail hygiene behaviors were more likely to be observed in individuals with stronger behavioral and stronger normative beliefs (p<0.05). Conclusions: More specific infection control guidelines for "nail art" among dental workers should be established and promoted, so that both patients and dental workers can interact in a safe environment.

The surgical approach for humeral implant failure can be challenging due to neurovascular anatomy and the possible necessity of osteosynthesis removal. We present a rare case of humeral nail bending after secondary trauma in a patient with preexistent nonunion of the humerus after intramedullary nailing. During revision surgery, the nail was sawed in half and the distal part was removed, followed by plate osteosynthesis with cable fixation to achieve absolute stability. The patient regained a full range of motion 1 year after surgery, and complete healing of the fracture was seen on imaging.

The restoration of the fingernail is not simple in case of amputated distal fingertip which involved the pulp and nail. The nail should maintain a length of at least 2 mm from the eponychium for an adequate grip and decent appearance. Various methods to reconstruct the fingernail bed are available. The nail bed graft from amputated finger or great toe, and free onychocutaneous flap are commonly used. The nail bed of the injured tip tends to be atrophied, deformed and failed as a graft. And the great toe is often turned down as a donor. We have restored satisfactorily the nail beds of three injured finger tips with eponychial cutaneous flaps. The pulps were reconstructed with either a reverse dorsal digital island flap or free pulp graft. Repeated again. A mean follow- up was six months. The nail grew up to the average of 3.7 mm. All patients were satisfied with the length of the nail and met with good cosmetic results. An eponychial cutaneous flap is useful to restore the nail of the distal fingertip amputation. The procedure is relatively simple and morbidity is minimum.

This study analyzed the qualifications necessary and manpower required in the Jeju nail art and make-up industry. We aimed to investigate the relationship between NCS education and national technical qualifications. For this study, 164 participants were given a questionnaire, and the collected data were analyzed via frequency analysis and multiple regression analysis using SPSS Ver. 18.0. The results of this study are as follows: 1. Matching job seekers with available positions was more difficult in nail art businesses than in makeup businesses. The main routes by which practitioners found jobs were Internet job sites and acquaintances. In addition, experience was the first consideration in hiring employees. 2. Those in high positions had less intention of employing students who had received NCS education, than those in lower positions. Intention to employ NCS graduates was high in businesses that found their employees through Internet job sites, vocational training institutes, acquaintances, or colleagues. Nail art workers prioritized NCS educational units in the following order: nail care, nail shop hygiene, gel nails, cosmetic nail removal, and tips/wraps. Makeup workers had the following priorities: basic makeup, wedding makeup, makeup shop safety, and hygiene management. They also mentioned basic occupational skills such as communication skills, interpersonal skills, and problem solving skills. Moreover, the new national licensing system was found to reflect competency in the most important skill sets.

This study examined the history of nail art in 20th century, defined characteristics of many techniques used on nails, and analyzed how those techniques have been utilized in recent nail art works. For the method of the study, books and previous studies on nail art were examined as primary sources, and newspaper articles on nail art were studied as references. Then, the case studies were conducted on photographs of nail art works published in Nail Holic in 2012. As a result of analyzing expression techniques of nail art featured on Nail Holic, there had been a total of 517 works created using a single technique. The reason why hand painting is used very frequently is because artists can draw unique images of their own to create various designs according to their tastes. Rhine stone is also very popular, because stones are easy to apply and various in their shapes and colors. There were a total of 555 works created using two or more techniques. The most important point to examine is that hand painting, rhine stone, and 3D art were most popular among all techniques. These works featured highly various effects and images by combining flat effect of hand painting with three-dimensional effects of rhine stone or 3D art. The tendency can also be found in the fact that there have been many works using techniques of flat effects such as decal or marbling combined with techniques of three-dimensional effects such as rhine stone or 3D art.

The purpose of this study was to clarify that the effect of consumer's perception of nail store attributes has on intent to revisit (focus on independent stores) by performing quantitative research. The importance of nail stores is increasing with sales amounts and the number of workers, however, previous research in this area is not complete. The reason that this qualitative research should be done before the quantitative research is due to the scant theoretical background in this matter. As the nail market is steadily increasing, determining the factors to make a successful and influential store leading to revisits is very meaningful both academically and in business. For the quantitative study, consumers from 20 years old to less 60 years old who had purchased nail service at independent nail stores were included in the survey. Quota sampling was adopted in the areas where the independent nail stores were located from May 10th to May 30th, 2019, and 262 questionnaires were collected, and those containing insincere respondences were excluded. The most important nail store attribute was reliability (store name value, relationship with workers and A/S) and then the physical environment, economics, product, and promptness. The result depended on demographic factors- younger and lower-income respondents put a premium on the physical environment, promptness, and economics, on the other hand, older and higher-income respondents placed a priority on reliability. The correlation analysis result is that all store attributes (reliability, physical environment, economics, promptness, product) show a statistical significance. A multiple regression analysis was conducted to determine the effects of nail store attribute importance on revisit intention. Promptness, economics, and the physical environment have a statistically significant effect on the consumer's revisit intention.

The several computer programs for the design of soil nailed wall are often used in Korea. However, these programs have been used without and practical justification. Therefore, in order to evaluate the applicability of these programs for the design of soil nailing, these computer results were analyzed and compared with one another. The performance evaluations by the available programs, such as SNAILZ, TALREN97, SLOPE/W STABL6, and NAILMI6, were applied and the applied data were from 6 case history(21 section). The estimated factors of safety with available programs were compared with observed horizontal deformation from the field. This study showed that the program SNAILZ is most adequate tool for the design of soil nailed wall. Also, The finite element program SOILSTRUCT was applied for the analysis of nail inclination effect in soil nailed wall. The program SOILSTRUCT showed that the most optimal inclination of nail was $20^{\circ}$. However, the effect of nail inclination on the wall deformation was negligible. Also, the tension force of the nail were increased as the nail inclination increased, and the tension force of the nail increased as the depth increased, except the deepest nail. Therefore, the larger diameter nail should be considered if the inclination of nail is steeper than the suggested range, and the deeper nails should have the larger diameters than those of shallower nails except for the deepest one.
