  • Purpose: A correlation between the rotating direction and rotation amount according to the eccentricity was analyzed in the present study when fitting the toric soft contact lens. Methods: One hundred fourteen eyes of with-the-rule astigmatism in 20s and 30s were appropriately applied toric soft contact lens by the guideline of manufacturer and fitting evaluations and analyzed the rotating direction and rotation amount when fixating at primary position and 8 different directions of gaze. The speed of reorientation and the correlation between the rotation amount and cornea eccentricity were also analyzed when rotating $45^{\circ}$ each toward the temporal and nasal direction. Results: The cornea eccentricity and rotation amount was shown positive correlation. For the gaze of direction, it was identified that the gaze of directions other than the gaze of direction towards the nasal and temporal had correlation, and among them, the gaze of directions to superior and the superior-temporal showed the tendency of decreasing rotation amount as the cornea eccentricity increased. On the contrary, the gaze of direction towards the inferior, inferior-temporal, superior-nasal, and inferior-nasal showed tendency of increasing rotation amount as the cornea eccentricity increased thus, it was identified that the cornea eccentricity showed different correlation according to the gaze of direction. For the case of re-orientational speed, the speed of lens reorientation in the group having the smallest corneal eccentricity was fastest in both direction but was not significantly different. Conclusions: Considering cornea eccentricity to current method of prescribing toric soft contact lens which is based on total astigmatism, it will be helpful to establish the optimal axis stabilization.

  • This study aims to investigate the effect of core-self evaluation on work-family facilitation(work to family facilitation, family to work facilitation), job satisfaction and turnover intention among non-regular workers in Korean food service industry. In order to examine the hypothesized relationships, frequency analysis, confirmatory factor analysis, reliability analysis, correlation analysis and covariance structure analysis were performed using SPSS(10.0) and AMOS(4.0). The results showed that core-self evaluation had a significantly positive effect on both of work to family facilitation and family to work facilitation. In the case of relationship between work-family facilitation and job satisfaction, only family to work facilitation had a positive effect on job satisfaction while there was no evidence of a significant relationship from work to family facilitation to job satisfaction. Additionally, job satisfaction had a significantly negative effect on turnover intention. The article concluded with managerial implications for managerial and future research directions.
