  • This study analyzes the effects of the KTX driver's person-environment(job, organization, Coworker) fit on job satisfaction, organizational commitment and turnover intention. It, additionally, examines the mediating effect of job satisfaction and organizational commitment between person-environment fit and turnover intention. Consequence of the analysis indicates that person-environment fit has mostly meaningful influences on job satisfaction, organizational commitment and turnover intention. But person-job fit makes a meaningless impact on job satisfaction, and person-coworker fit also makes a meaningless impact on job satisfaction and turnover intention. The mediating effect of job satisfaction and organizational commitment is mostly effective, but the mediating effect of job satisfaction does not affect the relation between person-organization fit and turnover intention. In conclusion, this study implies that, in order to grasp KTX driver's turnover intention and to protect actual turnover, it is important to enhance job satisfaction and organizational commitment as well as to improve overall person-environment fit.

  • This study compares the difference of fit factors (FF) and visual acuity according to masks and eyeglasses preferences for 54 participants. We the precautions and behaviors of discomfort when wearing masks of eyewear wearers. Contact lens discomfort and priority action of complaints was investigated Glasses fitting factors is Optical Center Height(OH), Vertex Distance(VD) and Pantoscopic Angle(PA). We measured those factors and expressed by the ratio of standard point and change point. Quantitative fit factor was measured by Portacount Pro+ 8038. Also, we selected to 6 exercises among 8 exercises OSHA QNFT (Quantitative Fit testing) protocol to measure the fit factors. The pass/ fail criterion of FF was set at 100. Visual acuity(VA) test chart is developed by Chunsuk Han was used, Descriptive statistics was performed. Descriptive statistics(SAS ver 9.2), it is used geometric means, Wilcoxon analysis(P=0.05) When wearing the mask preferentially, fit factor(FF) was high according to the step of glasses fitting parameter. on the other hand, when the glasses first choice, the visual acuity(VA) was high. there was no significant difference. In the case of fit factor (FF), mask first choice/ glasses first choice is OH (p=0.671/ p=0.332), VD (p=0.602/ p=0.571) and PA (p=0.549/ p=0.607). Visual acuity (VA), mask first choice/ glasses first choice is OH (p=0.753/ p=0.386), VD (p=0.815/ p=0.557) and PA (p=0.856/ p=0.562). The workers of workplace and office chose glasses but occupational health workers and students chose mask. In case of discomforts, it was suggested to remove the mask and tolerate discomforts. The main discomforts and usual action of lens were dryness, hyperemia, foreign body sensation, ophthalmodynia, decreased vision and glasses wearing. Therefore, it is necessary to develop a mask wearing method education program considering glasses fitting and develop a hybrid model that minimizes inconvenience when wearing glasses and a mask at the same time.

  • This paper has two primary objectives: (1) to propose a comprehensive theoretical model that incorporates valuable insights from two complementary streams of research, and (2) to empirically test the model that explain the task-media fit and satisfaction of customer contact center users. The comprehensive model was tested using LISREL analysis on the sample of 232 users who have experience with the customer contact center. The model was supported in customer contact center context, accounting for 29% of the variance in the task-media fit, 53% of the variance in the perceived ease of use, 61% of the variance in the perceived usefulness, and 52% of the variance in the user satisfaction. The results showed that the task-media fit, the perceived ease of use, and the perceived usefulness play a significant role in influencing the user satisfaction of the customer contact center. In addition, task analyzability, media richness, media interactivity, and self-efficacy were found to influence the task-media fit. The paper concludes with discussions and implications for researchers and practitioners.

  • This study provides basic information for the convenient size selection of T-shirts in an online purchasing environment. The best preferred T-shirts fit was selected among five sizes of T-shirts according to body size group. The subjects were 103 students majoring in clothing. After setting a virtual model with her own body sizes, the subjects chose the best preferred fit among five sizes of T-shirts that included the one suitable to their bust circumference, two smaller T-shirts and two larger T-shirts. As a result, they preferred the fit of larger size T-shirts than body size, but they preferred a different fit by the body characteristic group such as waist height group and hip circumference group. T-shirt length was affected by waist height; in addition, shoulder ease was affected by hip circumference and bust circumference. Therefore waist height and hip circumference should be considerable sizes when consumers choose T-shirts sizes with a preferred fit.

  • Purpose: The study examined the effects of ethical sensitivity and person-environment fit on person-centered care of nurses in long-term care hospitals. Methods: The participants were 111 nurses. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and multiple regression analysis with the SPSS program. Results: The mean of person-centered care was 2.95±0.62 out of 5. There were significant differences in person-centered care in terms of age, shift pattern, total clinical career, and educational experience of person-centered care. Person-centered care and ethical sensitivity, person-centered care and person-environment fit showed a positive correlation. Factors affecting the person-centered care were the age (20-29), shift pattern (three shift), person-environment fit. The explanatory power was 42%. Conclusion: These results can be used to increase the person-environment fit and adopt a differented approach based on age and shift pattern in order to enhance person-centered care. Therefore, it is necessary to develop and apply an person-centered care program for nurses in long-term care hospitals.

  • Purpose: Drawing on person-environment fit theory and social cognitive theory, this study aimed to examine how self-efficacy affects nurses' workplace well-being via person-job fit and the moderating role of digital competence. Methods: A two-wave survey was conducted to collect data. Data were collected from six hundred and ninety-five nurses at three Chinese hospitals between May 2022 and September 2022. We employed hierarchical regression analysis and bootstrapping to analyze the data. Results: Self-efficacy positively influenced person-job fit (β = .55, p < .001), which positively affected nurses' workplace well-being (β= .32, p < .001). Person-job fit mediated the effect of self-efficacy on nurses' workplace well-being. Additionally, digital competence strengthened the positive impact of self-efficacy on person-job fit (β = .12, p < .001). Conclusion: Recruiting nurses with both self-efficacy and digital competence benefits hospitals. It is critical for nurses to improve their digital competence for achieving person-job fit and attaining workplace well-being in the post-coronavirus disease 2019 (COVID-19) era.

  • The purpose of this study was to examine the effects of perceived fit and brand transfer on extension evaluation in luxury fashion brands. The instrument for this research was a self-administered questionnaire based on a previously developed scale. The variables addressed in this scale included perceived fit, brand value for both parent brand (clothing) and extension brand (home line), extension brand association, and purchase intention of the product in extension brands. The participants in this research comprised of 215 female consumers between the ages of 19 and 51 demographically distributed nationwide. Data were analyzed by descriptive statistics, paired t-test, factor analysis, and regression analysis via SPSS 12.0. Findings showed that brand value consisted of two factors: cognitive and hedonic value in luxury fashion brands. Parent brand value was significantly related to perceived fit with a positive effect on brand association and hedonic value in extension brands. With respect to brand transfer, cognitive value of the parent brand increased the extension brand's cognitive value, while hedonic value of the parent brand increased the extension brand's hedonic value. In addition, purchase intention of the product in the extension brands was determined by the perceived fit and hedonic value of extension brands. This study also discusses the managerial implications for marketers in developing effective luxury brand extensions into new product categories, which leads to a synergy effect in building brand equity in the luxury fashion market.

  • This study aims to investigate the influence of person-organization(P-O) fit on job satisfaction, and turnover intent mediated through goal commitment using structural equation modeling. An experimental design is applied to test seven hypotheses that reflect the research questions. Five star deluxe hotel employees are targeted for sampling. A total of 180 faithful cases out of 250 cases have been analyzed. To analyze the data, descriptive statistics and multivariate analysis of variance, and structural equation modeling(SEM) are employed using SPSS 19.0 and AMOS 4. The results indicate the hotel employees' perceived P-O fit is positively associated with goal commitment and job satisfaction while negatively linked with turnover intent. Also, goal commitment has a positive effect on job satisfaction while having a negative effect on turnover intent, mediating between P-O fit and organizational outcomes. Therefore, the needs to evaluate P-O fit and goal commitment during recruitment and after organizational entry have been raised.
