The purpose of this study is to identify function of make-up as an Important variable in terms of its influence to psychology of performers and outcome of their performance. From June to November 2004 performers in 4 types of fields, i.e., opera, musical, drama and dancing being performed in Seoul and Cheongju were chosen as subjects and totally 450 questionnaires were prepared and distributed and among them 416 were used as data for final analysis. For data analysis frequency analysis, factor analysis, T-test, one-way ANOVA, path analysis, chi-square test were conducted by means of SPS 12.0 and MOS 4.0 statistical programs and as ex post facto checking Duncan's multiful range test was conducted. Make-up is an important element in acting and it has great influence on level of psychological satisfaction of an individual. It was disclosed that psychological factor of concentration and lethargy have direct bearing on acting performance. In order to maximize actor or actresses performance skill perfect make-up is essential and role of make-up specialist can become a critical factor for inducing success in performance. Role and duty of make-up artists in terms of scope of their responsibility should be extended so that they may give their full support to the performers to be most successful in their performance.

The purposes of this study were to analyze causes of wife abuse through married couples as the research subject. The study employed ecological perspective to the study of wife abuse as an multiple dimensional and integrated paradigm combined with isolated theories of other research. The subjects were 369 married couples who live in Gwangju area. Data were analyzed with Cronbach'α, factor analysis, basic statistics, paired-t test, 1-test, ANOVA, Duncan's test, correlation analysis, stepwise multiple regression analysis. and hierarchical regression analysis using the SPSS 10.0 for windows. The major findings were as follows; 1. The psychological abuse score, physical abuse score, and sexual abuse score were lower than median without exception. Hut prevalence rates of wife abuse were considerably serious; 91.9% psychological abuse, 44.4% physical abuse, and 53.7% sexual abuse. 2. The results of the hierarchical regression analysis indicated that the marital conflict had the strongest impact on wife abuse. And the attitude toward wife abuse of husband, hostility of husband, exposure experience of domestic violence during a growth period of husband, perception toward social violence of husband, exposure experience of domestic violence during a growth period of wife, drinking problem of husband, and interpersonal relationships stress of husband had influenced on wife abuse. These variables accounted for 49.5% of variance of wife abuse behaviors. As the result of the study, it concludes that the ecological systemic approach on the cause of wife abuse is useful as a theoretical instrument. Suggestions and implications are made for further research and practical application.

Since its development in the early 1980's the force balance technique has become a standard method in the efficient determination of structural loads and responses. Its usefulness lies in the simplicity of the physical model, the relatively short records required from the wind tunnel testing and its versatility in the use of the data for different sets of dynamic properties. Its major advantage has been the ability to provide results in a timely manner, assisting the structural engineer to fine-tune their building at an early stage of the structural development. The analysis of the wind tunnel data has evolved from the simple un-coupled system to sophisticated methods that include the correction for non-linear mode shapes, the handling of complex geometry and the handling of simultaneous measurements on multiple force balances for a building group. This paper will review some of the components in the force balance data analysis both in historical perspective and in its current advancement. The basic formulation of the force balance methodology in both frequency and time domains will be presented. This includes all coupling effects and allows the determination of the resultant quantities such as resultant accelerations, as well as various load effects that generally were not considered in earlier force balance analyses. Using a building model test carried out in the wind tunnel as an example case study, the effects of various simplifications and omissions are discussed.

An analysis was conducted to predict the behavior of gasket by applying an optimal-strain energy-density function selected through a uniaxial tensile test and an analysis of the gasket used in an actual hydrogen fuel cell. Among the models compared to predict the materials' properties, the Mooney-Rivlin secondary model showed the behavior most similar to the test results. The maximum stress of the gasket was not significantly different, depending on the location. The maximum surface pressure of the gasket was higher at positions "T" and "Y" than at other positions, owing to the branch-shape effect. In the future, a jig that can measure the surface pressure will be manufactured and a comparative verification study will be conducted between the test results and the analysis results.

Objectives: This study was conducted to confirm the relationship between role conflict, positive psychological capital, and the psychological well-being of dental hygienists and to provide data for improving professionalism by increasing the psychological well-being of dental hygienists. Methods: From May 21 to June 22, 2023, 190 data were collected through an online community of dental hygienists. The collected data were analyzed IBM SPSS program ver. 23.0 and AMOS ver. 26.0. Statistical analysis methods, convergent validity test, structural equation model analysis, and model fit were performed using independent sample t-test, one-way ANOVA, confirmatory factor analysis, structural model fit test, and path analysis. Results: The lower the role conflict of dental hygienists and the higher the positive psychological capital, the higher the psychological well-being. The lower the role conflict, the higher the positive psychological capital. However, there was no mediating effect between positive psychological capital and role conflict, as it was not statistically significant. Analysis of the total effect of role conflict and positive psychological capital on psychological well-being revealed that positive psychological capital had a greater influence on psychological well-being than role conflict. Conclusions: Psychological well-being was related to positive psychological capital and role conflict. Future efforts are needed to improve positive psychological capital and psychological well-being of dental hygienists and reduce role conflict.

This study attempts to develop new simplified approximate formulas to predict the fundamental natural periods of vibration (T) for bearing wall systems engaged with special reinforced concrete shear walls (RCSW) under seismic loads. Commonly, seismic codes suggested empirical formulas established by regression analysis of measured T for buildings during earthquake motions. These formulas depend on structure type, building height, number, height and length of SW, and ratio of SW area to base area of structure. In this study, a parametric investigation is performed for T of 110 selected models of bearing RCSW systems with varying structural height, configuration of horizontal plans including building width, number and width of bays, presence of middle corridors and core SWs. For this purpose, a 3D non-linear response time history (TH) analysis is implemented using ETABS v16.2.1. New formulas to estimate T are anticipated and compared with those obtained from formulas of IBC 2012 and ASCE/SEI 7-10. Moreover, the study examines responses of an arbitrarily two selected test model of 60 m and 80 m in height with presence of SWs having middle corridors. It is observed that the performance of the tested buildings is different through arising of considerable errors when using codes' formulas for estimating T. Accordingly, using the present proposed formulas exhibits more reasonable and safer design compared to codes' formulas. The results showed that equitable enhancement is promising to improve T formulas approaching enhanced and accurate estimation of T with reliable analysis, design, and evaluation of bearing RCSW systems.

This study was a cross-sectional descriptive investigation study that analyzed the effects of spiritual well-being on stress coping in twenties. Data collection period was from May 1, 2019 to May 20, and 207 people voluntarily participated in the study. The sub-factors of spiritual well-being consisted of religious well-being and existential well-being. The types of stress coping consist of active coping, passive coping, aggressive coping, evasive coping, and social supportive coping. Data was analyzed using frequency analysis, t-test, Pearson correlation and multiple regression analysis using SPSS 18.0. As a result of the analysis, 90 (43.5%) were male and 117 (56.5%) were female. The 71.0% of the participants had no religion, the Buddhists were 14.5%, other religions were 5.8%, Protestants were 4.3%, Catholics were 2.9%, and Won Buddhists were 1.4%. Active coping in stress coping was correlated with religious well-being (r=-.357, p<0.01) and existential well-being (r=.301, p<0.01) under statistical significance. Religious well-being was significantly higher in males (Mean=2.87, SD=.753) than females (Mean=2.49, SD=.772, p<0.01). Existential well-being was also higher in males (Mean=4.25, SD=.841) than in females (Mean=3.95, SD=.694, p<0.01). The religious well-being was significantly higher than active coping (t=6.183, p<0.01), passive coping (t=-3.595, p<0.01), aggressive coping (t=1.991, p<0.05). Existential well-being was significantly higher than active coping (t=5.339, p<0.01), aggressive coping (t=1.659, p<0.05), evasive coping (t=-3.709, p<0.05) at the statistical significance level. Based on the results, it can be suggested that it was necessary to systematically plan spiritual well-being program as a way to cope with stress by knowing that spiritual well-being positively affects active, aggressive stress coping.

Purpose: To investigate whether volumetric analysis based on T2WI and contrast-enhanced (CE) T1WI can distinguish between isocitrate dehydrogenase-1 mutation-positive ($IDH1^P$) and -negative ($IDH1^N$) glioblastomas (GBMs). Materials and Methods: We retrospectively enrolled 109 patients with histopathologically proven GBMs after surgery or stereotactic biopsy and preoperative MR imaging. We measured the whole-tumor volume in each patient using a semiautomatic segmentation method based on both T2WI and CE T1WI. We compared the tumor volumes between $IDH1^P$ (n = 12) and $IDH1^N$ (n = 97) GBMs using an unpaired t-test. In addition, we performed receiver operating characteristic (ROC) analysis for the differentiation of $IDH1^P$ and $IDH1^N$ GBMs using the tumor volumes based on T2WI and CE T1WI. Results: The mean tumor volume based on T2WI was larger for $IDH1^P$ GBMs than $IDH1^N$ GBMs ($108.8{\pm}68.1$ and $59.3{\pm}37.3mm^3$, respectively, P = 0.0002). In addition, $IDH1^P$ GBMs had a larger tumor volume on CE T1WI than did $IDH1^N$ tumors ($49.00{\pm}40.14$ and $22.53{\pm}17.51mm^3$, respectively, P < 0.0001). ROC analysis revealed that the tumor volume based on T2WI could distinguish $IDH1^P$ from $IDH1^N$ with a cutoff value of 90.25 (P < 0.05): 7 of 12 $IDH1^P$ (58.3%) and 79 of 97 $IDH1^N$ (81.4%). Conclusion: Volumetric analysis of T2WI and CE T1WI could enable $IDH1^P$ GBMs to be distinguished from $IDH1^N$ GBMs. We assumed that secondary GBMs with $IDH1^P$ underwent stepwise progression and were more infiltrative than those with $IDH1^N$, which might have resulted in the differences in tumor volume.

The purpose of this study is to develop the system which convert the optical difference of teeth texture between intact enamel and incipient caries lesion into shade difference by laser fluorescence and to develop new and simple caries activity test using laser fluorescence. The experimental design of this study consists of three parts. In first part, a new method for the in vitro assessment of changes in initial enamel caries lesion of Bovine teeth using laser fluorescence is tested. In second part, in vivo assessment undertaken. Number of teeth which showed incipient carious lesion on buccal surface examined by laser fluorescence was compared with the caries activity test of $Cariescreen^{(R)}$ test and other oral environmental test of dDfFtT. In third part, new caries activity test measured by laser fluorescence was developed on the basis of above results and evaluated the sensitivity, specificity, and diagnostic power. Optical density measured by laser fluorescence was increased as increasing the depth of incipient carious lesion and showed high correlation$(\gamma=0.7015)$ with lesion depth. Optical density showed direct proportion to lesion depth. Linear equation was obtained between the optical density and the lesion depth by regression analysis. The result of caries activity test with laser fluorescence showed high correlation with those of $Cariescreen^{(R)}$ test and dDfFtT examination. Caries activity test with laser fluorescence showed 48% of sensitivity, 52% of specificity, and 45% of diagnostic power on the basis of dDfFtT examination, and also showed 48% of sensitivity, 51% of specificity, and 36% of diagnostic power on the basis of $Cariescreen^{(R)}$ test. In regard above result, caries activity test with laser fluorescence considered to be reliable for caries activity test compared with other oral environmental test. and it was also considered to be practical because it would be simple, inexpensive, and time saving method.
