The purpose of this research was to examine the discrimination between grit and passion; and to compare the relationship between grit and passion between eastern and western culture. The participants were 208 Korean and 251 American undergraduates. Multiple-group factor analysis confirmed the model of four (consistency of interest, perseverance of efforts, harmonious passion, and obsessive passion) factors by configural invariance and partial measurement invariance. Also we found positive correlation between consistency of interest and harmonious passion as well as negative correlation between consistency of interest and obsessive passion in the American sample. However, the correlation between grit(consistency of interest, perseverance of efforts) and passion(harmonious passion, obsessive passion) was not significant in the Korean sample. The results suggest that grit is not accompanied by passion among Korean university students. Findings empirically highlight the distinctiveness of grit and passion and the possibility of cultural differences in grit and passion, which were usually discussed western cultures.

The purposes of this study are to investigate what star marketing is and to examine whether star marketing influences clothing purchase behavior of adolescents or not. The concept and the instances of star marketing were reviewed and the characteristics and clothing behavior of adolescence were analyzed. The data were obtained from questionnaires completed by 341 middle and high school students and analyzed by frequency, t-test, chi-square test, cluster analysis, ANOVA, and Scheffe test. The Cronbach's alphas were calculated for the internal consistency. The results of the study are as follows. The sample was classified into three groups(high interest/high awareness group, high interest/low awareness group, and low interest/low awareness group) by the interest of TV watching and TV stars, the identification with TV stars, and the awareness and the interest of star marketing. There were significant differences in clothing purchase motives, the use of information sources, clothing buying places, clothing purchase frequency, and clothing expenditure among three groups.

Massively Multiplayer Online Game (MMOG) is one of diverse applications where more than hundreds of users enjoy experiencing virtual worlds. Voronoi-based Overlay Network (VON) is proposed to reduce a bandwidth consumption in P2P MMOGs and Vorocast also is made using message forwarding in VON. We propose a dynamic area of interest (AOI) management method that solves problems such as less consistency and high latency due to sending position updates to more neighbor nodes from the message originator in forwarding scheme. Our scheme provides the higher consistency and reduces latency by combining direct connection scheme and Vorocast scheme compared to existing schemes. The proposed model is evaluated through simulations.

In this paper we investigate some concepts frequently called in sample surveys such as 'representative of sample' as well as 'consistency', 'unbiasedness', and 'efficiency' in estimation. The first is strongly related with sampling procedure including coverage rate of survey population, response rate in establishment survey, and recruit rate of final samples. The others, however, are concerned with both sampling design and corresponding estimators simultaneously. Whereas both consistency and unbiasedness are based on the representative sample, efficiency does not depend on the representative sample. The representative of sample can be increased by raising the rate of coverage, response and recruit as well. Consistency may be investigated according to variables of interest and auxiliary variables. The well-known raing-ratio weighting method is a method to increase consistency of auxiliary variables by means of matching population size in each cell. Efficiency is not directly related with the representative of sample, and allocation methods such as proportional and Neyman allocation in stratified sampling and post-stratification are all methods to increase the efficiency of estimation under the condition of satisfying the representative of sample.

The purpose of this study is to understand the mediating effect of grit in the relationship between academic achievement satisfaction and Academic Engagement of middle school students. To this end, a survey was conducted on 575 middle school students in Changwon, Gyeongsangnam-do, on academic achievement satisfaction, Academic Engagement, and grit. This research was carried out by hierarchical regression analysis was conducted to understand the correlation analysis and mediating effect between major variables, and The significance of the mediating effect was verified by the Sobel test. As a result of the study, First, correlation analysis revealed a positive correlation between academic achievement satisfaction, grit, and Academic Engagement. Second, regression analysis showed that both consistency of interest and perseverance of effort were partially mediated between academic achievement satisfaction and Academic Engagement. This means that academic achievement satisfaction not only directly affects middle school students' Academic Engagement, but also has an indirect effect through grit. Finally, In order to increase the academic enthusiasm of middle school students, learning counseling plans such as education and counseling plans to improve academic interest and develop various learning motivation improvement programs were discussed.

Purpose : To retrospectively evaluate the usefulness of diffusion-weighted images, ADC maps and conventional MR images for determination of brain tumor consistency. Materials and Methods : Twenty-three patients with brain tumor underwent MR examinations with T1, T2 and diffusion-weighted images. Regions of interest (ROIs) were drawn in the tumors, and the measured signal intensities (SI) were normalized with the contralateral side. We evaluated the correlation between SI ratios from various images and tumor consistency assessed at surgery. In three patients with both cystic and solid components, each component was evaluated independently. Qualitatively observed SIs were also correlated with tumor consistency. Results : Statistical analysis revealed significant correlation between tumor consistency and ADC ratio (r = -0.586, p = 0.002), SI ratios on T2-weighted images (r = -0.497, p = 0.010), and observed SIs on T2-weighted images (r = -0.461, p = 0.018). The relative ratio of ADC value correlated with tumor consistency most strongly. Conclusion : The measured ratio of ADC, SI ratio and observed SI grade on T2-weighted images can provide valuable information about the consistency of brain tumor.

This study is a descriptive research to investigate the effects of nursing college students in graduation year, self-management competency and grit on employment preparation behavior. The data were analyzed using SPSS 26.0 program, frequency analysis, t-test, ANOVA, Pearson's correlation, and multiple regression. Self-management competency(r=.41, p<.001) and persistence of effort(r=.44, p<.001) of the grit sub-factor showed a positive correlation with employment preparation behavior. Interest consistency(r=-34, p<.001) of the grit sub-factor and employment preparation behavior showed a negative correlation. Self-management competency(β=.27, p<.01) and persistence of effort of the grit sub-factor(β=.22, p<.01) had a positive effect on employment preparation behavior. Interest consistency of grit sub-factor(β=-.32, p<.001) showed a negative effect on employment preparation behavior. In order to promote the employmentt preparation behavior of nursing students, it is necessary to improve self-management competency and persistence in effort. It also suggests that a strategy to suggest various nursing-related employment fields is needed to reduce interest consistency.

This paper suggests an algorithm to improve the tracking performance for an underwater acoustic target using the feedback information of acoustic feature of a target. While conventional tracking algorithms use detected acoustic signals only, the proposed algorithm uses detected acoustic signals and target feature information as well. Since the proposed algorithm tracks only the selected measurements using target feature information, it prevents onset of unnecessary tracks and improves tracking performance for target of interest. Furthermore, it optimizes tracking parameters for the target of interest and guarantees robustness and consistency of the track. Some simulations are performed to demonstrate the improved tracking performance of the proposed algorithm.

The purpose of this study is to investigate the relationship of grit with well-being and self-efficacy. Grit was considered as a two-factor variable with consistency of interest and perseverance of effort. For the empirical analysis, data were collected from the sample of 237 nurses working at general hospitals. Collected data were analyzed using SPSS 26 to test the hypothetical relationships. It was suggested that two factors of grit would be possible associated with well-being. However, the results of this study showed that the consistency of interest part of grit had non-significant effect on well-being, Perseverance of effort part of grit had indirect effect on well-being through fully mediation effect of self-efficacy. This study confirmed that grit, some how, positively related to well-being and variables such as, self-efficacy, could be a important variable to bridge grit to well-being. Further studies were suggested to perform studies on more about grit's two factors and unexplored external variables between grit and well-being of nursing professionals.
