PURPOSE. The aim of this study is to compare the casts obtained by using conventional techniques and liquid crystal display (LCD) three-dimensional (3D) print techniques in the All-on-4 treatment concept of the edentulous mandibular jaw. MATERIALS AND METHODS. In this study, a completely edentulous mandibular acrylic cast (typodont) with bone-level implants placed with the Allon-4 technique served as a reference cast. In this typodont, impressions were taken with the conventional technique and dental stone casts were obtained. In addition, after scanning the acrylic cast in a dental laboratory scanner and obtaining the Standard Tessellation Language (STL) data, 3D printed casts were manufactured with a 3D printing device based on the design. The stone and 3D printed casts were scanned in the laboratory scanner and STL data were obtained, and then the interimplant distances were measured using Geomagic Control X v2020 (3D Systems, Rock Hill, SC, USA) analysis software (n = 60). The obtained data were statistically evaluated with one-way analysis of variance (ANOVA) and Tukey's pairwise comparison tests. RESULTS. As a result of the one-way ANOVA test, it was determined that the stone casts, 3D printed casts, and reference cast values in all distance intervals conformed to the normal distribution and these values had a significant difference among them in all distance intervals. In Tukey pairwise comparison test, significant differences were found between casts at all distance intervals. In all analyses, the level of significance was determined as .05. CONCLUSION. 3D printed casts obtained with a 3D LCD printing device can be an alternative to stone casts when implants are placed in edentulous jaws. [J Adv Prosthodont 2022;14:379-87]

This paper is intended to grasp the characteristics of many bodices patterns which have been shown so far. The way is by selecting four characteristic kinds of patterns, making blouses offer the patterns and measuring ease. In measuring the degree of ease, $Scheff\`{e}'s$ paired comparison is made use of. In analysis, variation ratio has come out of analysis of variance, and significance is tested by producing estimated values between patterns. The Result is summed up as follows. 1. After wearing blouses made ofter different basic patterns and measuring ease, the analysis of variance is made about the sensory value of ease. The result is as follows. 1) In the ease of different patterns, all the areas are significant at the level of $1\%$ , regard- less of movements. 2) Under the influence of movements, the back area of arm hole is significant at the level of $5\%$ in narrow movements, and the front and the back area of arm hole are each significant at the level of $1\%$ in wide movements. 3) In the interaction of patterns and movements, bust and the under area of arm hole are each significant at the level of $1\%$ in narrow movements, and bust is significant at the level of $1\%$ in wide movements. 2. When comparing estimated values between patterns, the value of c is the largest and in the order of b,4, a. And in the other movements, the order changes into c,d, b and a. Thus the ease of blouses is different according to patterns. The reason for this is that the amount of ease of bust, the amount and location of darts, and sleeve cap height have complicate influences on the ease of blouses. Both sleeve cap height and the depth of arm hole have influences on the ease of sleeve. Consequently, in making clothes, it would be better to select and use proper patterns which go with the purposes and desings of clothes rather than to apply one pattern to various clothes.

The purpose of this research is to analyze the effects of social support on the job performance of workers at care facilities for elderly. For the study, a survey was conducted on 176 workers at care facilities for elderly in Gyeongsangbuk-do from the 5th of September of 5th of November, 2016. For the analysis, SPSS WIN 18.0 and Amos 21.0 programs were used to conduct t-test, one-way analysis of variance, correlation analysis and multiple regression analysis at a significance level of 5%. The research results were as follows. First, the level of social support on the workers varied depending on their marital status, religions and years of service, while no difference was found for different genders, ages, education levels, positions, monthly incomes and workloads. Second, the job performance of the workers varied with their marital status, with the married workers performing at higher level then single workers. Third, it was found that the job performance of workers at care facilities for elderly has positive correlation with the level of social support. This paper is required to be used as a primary source for political development on the job performance of workers at care facilities for elderly.

The first purpose was to identify the plantar pressure distributions (peak pressure, pressure integral time, and contact area) during level walking, and stair ascent and descent in asymptomatic flexible flatfoot (AFF). The second purpose was to investigate whether peak pressure data during level walking could be used to predict peak pressure during stair walking by identifying correlations between the peak pressures of level walking and stair walking. Twenty young adult subjects (8 males and 12 females, age $21.0{\pm}1.7$ years) with AFF were recruited. A distance greater than 10 mm in a navicular drop test was defined as flexible flatfoot. Each subject performed at least 10 steps during level walking, and stair ascent and descent. The plantar pressure distribution was measured in nine foot regions using a pressure measurement system. A two-way repeated analysis of variance was conducted to examine the differences in the three dependent variables with two within-subject factors (activity type and foot region). Linear regression analysis was conducted to predict peak pressure during stair walking using the peak pressure in the metatarsal regions during level walking. Significant interaction effects were observed between activity type and foot region for peak pressure (F=9.508, p<.001), pressure time integral (F=5.912, p=.003), and contact area (F=15.510, p<.001). The regression equations predicting peak pressure during stair walking accounted for variance in the range of 25.7% and 65.8%. The findings indicate that plantar pressures in AFF were influenced by both activity type and foot region. Furthermore the findings suggest that peak pressure data during level walking could be used to predict the peak pressure data during stair walking. These data collected for AFF can be useful for evaluating gait patterns and for predicting pressure data of flexible flatfoot subjects who have difficulty performing activities such as stair walking. Further studies should investigate plantar pressure distribution during various functional activities in symptomatic flexible flatfoot, and consider other predictors for regression analysis.

Background: This study was aimed at investigating the type of work of dental hygienists and identifying factors affecting the subjective health status according to hazardous risk factors in the working environment. Methods: From May 15 to 31, 2019, we surveyed 411 dental hygienists working at dental hospitals in the metropolitan area. SPSS 25.0 was used to perform the frequency analysis, t-test, one-way analysis of variance, Pearson's correlation analysis, and multiple regression analysis. Results: Regarding factors related to the degree of exposure to hazardous risk factors in the work environment and subjective health status, the more exposed the ergonomic (p<0.05) and psychological (p< 0.001)factors, the worse is the subjective health status. Conclusion: The results of this study suggest that the working environment should be improved for dental hygienists such that they can perform their duties in a safe environment.

Objectives: The aim of this study was to evaluate the shaping ability of newly marketed single-file instruments, Wave One (Dentsply-Maillefer) and Reciproc (VDW GmbH), in terms of maintaining the original root canal configuration and curvature, with or without a glide-path. Materials and Methods: According to the instruments used, the blocks were divided into 4 groups (n = 10): Group 1, no glide-path / Wave One; Group 2, no glide-path / Reciproc; Group 3, #15 K-file / Wave One; Group 4, #15 K-file / Reciproc. Pre- and post-instrumented images were scanned and the canal deviation was assessed. The cyclic fatigue stress was loaded to examine the cross-sectional shape of the fractured surface. The broken fragments were evaluated under the scanning electron microscope (SEM) for topographic features of the cross-section. Statistically analysis of the data was performed using one-way analysis of variance followed by Tukey's test (${\alpha}$ = 0.05). Results: The ability of instruments to remain centered in prepared canals at 1 and 2 mm levels was significantly lower in Group 1 (p < 0.05). The centering ratio at 3, 5, and 7 mm level were not significantly different. Conclusions: The Wave One file should be used following establishment of a glide-path larger than #15.
