Purpose: To investigate the effect of color soft contact lenses on the corneal thickness in young Korean population. Methods: The subjects consisted of 112 eyes (7 males, 49 females) with the mean age of $20.987{\pm}1.093years$ (range 20-25 years) in young Korean population during 2018. Test was compared the corneal thickness before and after wearing color soft contact lenses. The thinnest cornea thickness(TCT), central cornea thickness(CCT), pupil centre thickness(PCT), superior corneal thickness(SCT),inferior corneal thickness(ICT), medial corneal thickness(MCT), lateral corneal thickness(LCT) of the cornea was measured using the Pentacam pachymetry. The statistically analysis was perform the Shaparo-Wilk test. Results: The right eye was a statistically significant among the CCT,LCT, MCT and TCT values(p<0.001) in the compared the corneal thickness before and after wearing soft colour contact lenses. Also the left eye was a statistically significant among the LCT and MCT values(p<0.001) in the compared the corneal thickness before and after wearing soft colour contact lenses. However, there was no statistical difference (p>0.5) in the mean PCT between before and after wearing color soft contact lenses. Conclusion: These results suggested that the color soft contact lens wear can the effect the regional thickness of cornea. Therefore, the analysis of corneal topography with Pentacam can provide correct and useful diagnostic information of the morphology of the RGP contact lens fitting and diagnosis of corneal refraction surgery.

Purpose: This study is to figure out not only the characteristics relating to transfer time of inter-hospital transfer patient which is transferred by a private ambulance, but also factors influencing the transfer time. Methods: In this study, an analysis of 750 patients with high severity levels among those transferred to another hospital by a private ambulance in Busan for whole year of 2017. Results: The results showed that the following factors significantly influence the total inter-hospital transfer time: Ambulance crew (${\beta}=10.525$, p=.001) and patient and carer (${\beta}=37.606$, p<.001) when setting a doctor (selecting a medical institution) as a criterion; availability of the specialized care (${\beta}=12.435$, p=.008) when setting the near distance (reason for selecting a hospital for transfer) as a criterion. The explanatory power of this analysis was R2=0.423, whereas the explanatory power of calibration was R2=0.411. Conclusions: Factors that increase the total inter-hospital transfer time were the ambulance crew, and patient and carer's selecting a medical institution, and the reason for selecting a hospital where enables to offer the specialized care services.

Purpose: This study is basic data that I can provide the guidelines in order to the single man and women of the college students have positive the marital consciousness. Method: The subjects were 180 people as single man and women recruited from 3 college located in B city. Data were collected using structured questionnaire, and analyzed with the PASW 21.0 program. Results: The result to implement stepwise regression analysis is that the media perception from the woman and family strength are affected the significant influence(p=.007, p=.015) and explanation powers were 21.2%. The ego-identity from the man is affected the significant influence and $R^2$ were 10.9%. When looking through this results of the research, the man can be affected by the internal factor and the women can know to be influenced by the external factor. Conclusion: Accordingly, through the sex custom education the man decide to family strength, the women strengthens the factor which is internal than the external factor and it is positive, it is effective to form the outlook on marriage.

Purpose. In this study, two types of soft contact lenses with different materials were selected to compare the time of tear film destruction and high order aberrations before and after wearing. Methods. Thirty patients (60 eyes) in their 20s were included in this study. Two lenses with different materials, Group 4 (Etafilcon A) and Group 5 (Narafilcon A) were selected. Using aberration analyzer and keratometry, high-order aberration and tear film test (NIF-BUT, NIAvg-BUT) were performed before and after wearing. Results. When comparing the higher aberrations of the Etafilcon A and Narafilcon A lenses, the higher aberrations of the Narafilcon A lens were higher overall. For the initial tear film break-up time (NIF-BUT) after wearing, the Etafilcon A lens was reduced by 4.0 seconds and the Narafilcon A lens increased by 0.6 seconds. For the mean tear film break-up time (NIAvg-BUT) after wearing, the Etafilcon A lens decreased by 2.4 seconds and the Narafilcon A lens increased by 1.7 seconds. Conclusions. NIF-BUT and NIAvg-BUT of Narafilcon A lens were increased. The lens with relatively low water content and higher oxygen permeability than the lens with high water content has relatively less tear evaporation, which means that the time of destruction of the tear film is increased.

Purpose. This study is a descriptive study to investigate the effect of freshmen nursing students personality. Methods. Participants were 237 nursing students who studied in 2 nursing colleges in B metropolitan. The period of data collection was from April 1 to 12, 2019. All of this data is analyzed by Frequencies, mean, standard deviation, t-test, one way ANOVA, and Multiple regression using the SPSS 23.0 program. Results. First, the mean score of the personality and self-esteem were $4.03{\pm}0.57$ and $3.87{\pm}0.84points$. Second, personality was significantly different according to perceived family economic status, perceived interpersonal relations, academic stress, and satisfaction on nursing major. Third, the influencing factor in personality of participants was self-esteem, adjusted R2=.188(p<.001). Conclusions. Development of guidance program to improve level of personality and self-esteem of freshmen nursing students is recommended.

Purpose: The purpose of this study was to identify the effects of the gender role conflict on nursing professionalism in male nursing college students. Method: The subjects were 113 male college students in D and J city. The data were collected from April 24 to May 3, in 2017 using a structured questionnaire. The data were analyzed using the SPSS WIN 24.0 program. For data analysis, independent t-test, One-way ANOVA, Pearson's correlation coefficient and multiple linear regression analysis were carried out. Results: The results are follows. First, the individual characteristics in gender role conflict were significantly different in motivation(F=2.62, p=0.028) and the entering college decision(F=3.14, p=0.028), and nursing professionalism were significantly different in the entering college decision(F=4.34, p=0.006). Second, a negative relationship was observed between the gender role conflict and nursing professionalism(r=-.287, p=<0.01). The success, power and competition(${\beta}=0.19$, p<0.05) and male superiority(${\beta}=-0.47$, p<0.001) were found to influence nursing professionalism. Conclusion: These results highlight the need to develop educational intervention to lower the superiority of the male and to encourager success, power and competition of male nursing college students.
