Purpose: This systematic review aims to provide an overview of research related to grit among nursing college students in South Korea. Methods: A literature search was done using RISS, KISS, and KCI to identify studies written in Korean from 2010 to 2023. Results: A total of 210 articles were searched, and a final 26 articles were selected in the analysis based on inclusion and exclusion criteria. Three researchers independently coded the characteristics and key content of each paper, including research objectives, methodology, study participants, grit measurement methods, and the relationship between grit and other variables. Subsequently, these coded findings were used to collectively analyze and derive overarching themes through discussion. The analysis results indicated that grit was influenced by factors such as academic major satisfaction, academic performance, and resilience. Grit was found to be a psychological factor affecting nursing students, influencing both major-related competencies and career-related factors. Conclusion: The findings of this review contribute to a deeper understanding of grit within the specific demographic of nursing college students in South Korea and may inform future research and educational practices. In addition, this systematic review provides a comprehensive understanding of the literature on grit among nursing college students in South Korea and serves as a valuable resource for future research and educational interventions in this context.

In this paper, we show the career path of college students from the perspective of positive psychology. Specifically we conducted the study to investigate a role of grit in the relationship between college students' occupational calling and academic achievement and career stress. 151 college students participated in this study and they completed the Korean version of the Calling and Vocational Questionnaire, Grit Scale, and Career Stress Scale. To assess their academic achievement, participants agreed to obtain their GPA from online system. The results of this study showed that occupational calling had a positive correlation with academic achievement and negatively correlated with career stress. In addition, it was confirmed that grit mediated the relationship between calling and academic achievement and career stress. Based on these results, the positive effects of occupational calling of college students, implications of this study, and suggestions for future research are discussed.

The microstructure of vitreous bonded abrasives, which are used as the essential materials in the precise grinding, was investigated theoretically using two particle model. In this paper, a general equation applicable for a case in which there is a gap between abrasive grits is suggested. As a result, it was known that both the volume ratio of grit to glassy bond(V\ulcorner/V\ulcorner) and porosity(V\ulcorner) are the function of $\alpha$(the ratio of distance between grit to diameter of grit) and $\theta$(the angle from the center of pore to that of grit). Because the value $\alpha$ and $\theta$ can be get easily by using these suggested equations, the microstructure could be explained quantitatively. Also the raised error with the increasing amount of bond was modified by the simple assumption. As a result, in that case, both V\ulcorner/V\ulcorner and V\ulcorner were known to be the function of $\alpha$ and $\theta$(the ratio diameter of pore to that of grit).

It is essential to accurately predict the change in water level, velocity, and flow rate for each passage of the grit chamber according to the operating conditions of the pump. In this study, VOF multiphase flow analysis was performed, and the flow characteristics of the grit chamber were predicted. As a result of simulations, the sedimentation phenomenon after the entrance of the grit chamber channel is expected to occur on the side walls. When 6 channels are used, the average speed of the channels is about 52% of the design standard, and when 4 channels are used, the value increases to 74% of the design standard. The average water level in the channels tends to decrease as the flow velocity increases, and the water level in the absorption well with a larger flow rate is maintained lower than that in the absorption well with a smaller flow rate.

Mucilage containing ${\gamma}-polyglutamic$ acid (PGA) was efficiently generated by the solid-state fermentation (SSF) of soybean grit by Bacillus firmus NA-1. B. firmus NA-1 was shown to be a glutamate-dependent strain for PGA production. The SSF of soybean grit was optimized in order to produce mucilage with a fortification of 5% glutamate, resulting in higher levels of mucilage production (6.14%) and a higher consistency index ($1.1\;Pa\;sec^n$). The sticky mucilage was comprised of 38% PGA, 7% levan, and some biopolymers. With regard to the viscoelastic properties of the mucilage solution, the viscous modulus (G") obtained from soybean grit fortified with 5% glutamate was approximately 64 times higher titan that of the mucilage solution obtained without glutamate. Although the addition of glutamate in the SSF of soybean grit influenced the rate of PGA production, the molecular weight of PGA remained unaltered, and was detected in a range between 1,400-1,440 kDa.

The purpose of this study was to examine influences on grit in the nursing student. The data were collected from 146 nursing students in the H university located Y city. The data were analyzed by descriptive statistics, T-test, ANOVA, Scheffe, Pearson's correlation coefficient, and multiple regression with SPSS 20.0 program. Grit was found to be in a significant positive correlation with academic stress, academic self-efficacy and major satisfaction. The result of the multiple regression indicates the major satisfaction, academic self-efficacy, academic stress and grade point average predict 22.5% of grit. Therefore, it is necessary to develop an intervention program to strengthen the grit of nursing students.

In a rapidly changing environment, it is essential for companies to develop their capabilities for sustainable growth. To this end, informal learning at work plays an important role for small and medium-sized enterprises that are having difficulties in human resource development. If the GRIT of workers and the spiritual leadership of leaders are maintained at an appropriate level, the effect of informal learning will increase. This study derived the following results through a survey of workers participating in the Work-learning Dual System in Korea. First, experience and feedback among informal learning activities have a significant positive effect on competency development. Second, the higher the level of the GRIT of workers, the greater the magnitude of the positive effect of experience and feedback on competency development, showing a positive moderating effect. Third, in the case of workers with high GRIT, capacity development is strengthened as experience or feedback increases, and the higher the level of spiritual leadership, the greater the scope of reinforcement. On the other hand, it can be seen that in the case of workers with low GRIT, competency development weakens as experience or feedback increases, and the higher the level of spiritual leadership, the greater the extent of the weakening.

Purpose: This study was conducted to identify the effects of grit on the work engagement of nurses and to identify the mediating effects of positive psychological capital and burnout in the relationship between grit and work engagement. Methods: The study subjects were 182 nurses who had been working in a general hospital for more than six months. The data were collected from July 12 to July 26, 2021. The collected 182 sets of data were analyzed by descriptive statistics, correlation analysis, and a hierarchical regression analysis using IBM SPSS statistics version 23.0 and also by bootstrapping using SPSS Process Macro. Results: As a result of the analyses, it was found that higher work engagement was associated with higher grit, higher positive psychological capital, and lower burnout. The mediating effects of positive psychological capital and burnout in the relationship between grit and work engagement were found to be both direct and indirect. Conclusion: This study provides basic data suggesting that an education program designed to reduce burnout and reinforce grit and positive psychological capital is necessary to promote the work engagement of nurses in clinical settings.

Purpose: The purpose of this study was to investigate the cutting efficiency of coarse grit diamond burs with air-turbine handpiece on natural tooth. Materials and methods: Four groups of coarse grit diamond bur were selected: Komet (A), Shofu (B), Premier (C), and Mani (D). The extracted maxillary central incisors were used, and ten cuts were made on each specimen, using the rotary diamond burs. The surface of each bur was measured at the upper, middle, and bottom of the bur with confocal laser scanning microscope and imaged with SEM. The data were analyzed with one-way ANOVA and t-test at the significance level of 0.05. Results: The surface roughness was measured. At the A diamond bur, the Sa values were $52.93\;{\mu}m$, $48.32\;{\mu}m$, $46.79\;{\mu}m$, $45.06\;{\mu}m$, and $43.43\;{\mu}m$ for control, test 1, 2, 3, and 4 respectively. The Sa values were $50.68\;{\mu}m$, $45.62\;{\mu}m$, $44.41\;{\mu}m$, $44.10\;{\mu}m$, and $42.46\;{\mu}m$ for B diamond bur, $58.02\;{\mu}m$, $55.53\;{\mu}m$, $52.22\;{\mu}m$, $48.26\;{\mu}m$, and $45.36\;{\mu}m$ for C diamond bur, and $50.11\;{\mu}m$, $46.73\;{\mu}m$, $45.46\;{\mu}m$, $42.58\;{\mu}m$, and $41.80\;{\mu}m$ for D diamond bur. Surface roughness after each bur use showed significant changes, but no significant difference was found in surface roughness change between bur systems. Conclusions: Surface roughness in the same bur system showed significant differences after each tooth preparation. However no statistically significant differences were found in surface roughness between bur systems. The SEM images between control and test 4 showed the abraded particles.

The purpose of this study was to compare gifted and non-gifted high school students on their perceptions of success, grit, aspirations, and achievement goal orientation. Of the 550 high school students surveyed from 4 high schools (i.e., two schools for gifted, two school for non-gifted) in three metropolitan cities, Korea, 496 (i.e., 153 gifted and 343 non-gifted) completed and returned the questionnaire yielding a total response rate of 90.18%. Measures of students' grit (i.e., consistency of interest, and perseverance of effort), aspirations (i.e., intrinsic aspirations - physical fitness, self-growth, affiliation, community contribution, and extrinsic aspirations - financial success, image, fame), achievement goal orientation (i.e., mastery, performance approach and performance avoidance), and perceptions of success (i.e., Success in life is pretty much determined by forces outside our control.) were administered. It was found that the majority of gifted students and non-gifted students perceived that "success is outside our control.", and chose 'hard-working' as the most influential factor on their success. 60.4% of non-gifted students chose 'wealthy family background' as the other most influential factor, whereas only 48.2% of gifted did. Gifted students had higher 'consistency of interest' and 'mastery goals' than non-gifted students. Hierarchical multiple regression analyses showed that grit (i.e., perseverance of effort) was the crucial contributors for enhancing both gifted and non-gifted students' mastery goals and performance approach goals. Results are discussed in relation to theoretical implications and school settings.
