Flat panel based digital radiography (DR) systems have recently become useful and important in the field of diagnostic radiology. For DRs with amorphous silicon photosensors, CsI(TI) is normally used as the scintillator, which produces visible light corresponding to the absorbed energy. The visible light photons are converted into an electric signal in the amorphous silicon photodiode. In order to produce good quality images, we need to understand the detailed behavior of DR detectors in radiation. We, therefore, investigated the relationship between DR outputs and X -ray in terms of absorbed energy, using the SPEC-78, X-ray energy spectrum model. We calculated the total filtration of X-ray equipment measuring air exposure and this value was used in the calculation of absorbed energy. The relationship between DR output and the absorbed energy of the X-ray was obtained by matching the absorbed energy with pixel values of real images under various conditions. It was found that the relationship between these two values was almost linear. The results were verified using phantoms made of water and aluminium. The pixel value of the phantom image was estimated and compared with previous results under various conditions. The estimated pixel value coincided with the results, although the effect of scattered photons introduced some errors.

The purpose of this study is to develop the Internet vulnerability index of adolescents. To do this, we used the original data of long - term follow - up survey for the internet overdependency cause analysis conducted by NIA in 2018, and analyzed the correlation between alternatives of internet vulnerability index and personal psychology by using linear regression analysis. Factor analysis showed that the relationship with the surroundings was indexed by adding 9 items to positive factors such as family acceptance, peer attachment, and teacher favorability. The relationship between the surroundings and self - stigmatization is confirmed, and the relationship between the surroundings and the Internet fragility is predicted to be negatively related, and the digital capacity is also assumed to be negatively correlated with the Internet vulnerability. In order to develop the specific form of the Internet vulnerability index, personal psychology and linear regression analysis were conducted. As a result, positive factors and R value of personal psychology were increased when considering the relationship with the environment and the digital capacity rather than the Internet overdependency model. Based on these implications, we discussed the implications and limitations of this study.

The objective of this paper is to investigate the effect of character traits of employees of consulting firm on job satisfaction through self-leadership and self-efficacy. The proposed model is based on big5 model of Coasta and McCrae(1992). To validate the proposed model, structural equation model is analyzed with the valid 140 questionnaires collected from Seoul and nearby cities by using Smart PLS 3.0. The results are as follows. First, extraversion has a positive effect on self-leadership, not on self-efficacy. Second, agreeableness has a positive effect on self-leadership, not on self-efficacy. Third, conscientiousness has a positive effect on both self-leadership and self-efficacy. Fourth, emotional stability does not have a positive effect on both self-leadership and self-efficacy. Fifth, openness to experience has a positive effect on both self-leadership and self-efficacy. Sixth, self-leadership has a positive effect on self-efficacy. Seventh, self-leadership has a positive effect on job satisfaction. Last, self-efficacy has a positive effect on job satisfaction. This research proves that, while the character of employees generally forms the meaningful relationship with self-leadership and self-efficacy, in some entries of Big 5 character elements it has still produced the different results with the previous researches, which betrays that the relationship between one's character and self-leadership and self-efficacy can differ according to the characteristic of jobs. It requires further study to prove how each of Big 5 elements differently effects on self-leadership and self-efficacy according to diverse characteristic of jobs.

This study aimed to examine the mechanisms underlying digital game usage behavior by applying the Theory of Planned Behavior and the Balance Theory. It investigated the influences of attitude, subjective norms, and perceived behavioral control on the intention to use digital games, as well as the differences in the application of the Theory of Planned Behavior model based on the balance state among individuals, significant others, and digital games. A total of 315 responses from adult PC game users were collected through an online survey conducted from October 21 to 25, 2021, and were analyzed using multiple regression analysis. The results revealed that attitude and perceived behavioral control had a significant positive impact on the intention to continue using digital games, while subjective norms did not exert a significant influence. By categorizing groups into balanced, unbalanced, and imbalance states based on the balance relationship, the application of the Theory of Planned Behavior model showed that in the unbalanced and imbalance groups, both perceived behavioral control and attitude had a positive impact on the intention to continue using digital games. However, in the balanced group, attitude only had a positive impact on the intention to continue game usage. This study contributes to understanding digital game users by examining both individual psychological factors and the influence of others on digital game usage behavior.

The purpose of the study is to investigate the effect of digital literacy, perceived usefulness, and perceived ease of use on Internet users' online purchase intention in Palestine, as well to examine the moderating effect of Internet users' socioeconomic characteristics - age and gender on the relationships between digital literacy and online purchase intention. An extended technology acceptance model (TAM) by including digital literacy was applied in this research. The study applied a quantitative method, where 400 respondents participated in a questionnaire. The collected data was tested against the research framework using the partial least squares (SEM-PLS) method. The findings indicate that digital literacy has a significant effect on perceived usefulness, perceived ease of use, and online purchase intention; there is a significant effect of perceived usefulness on online purchase intention, but not perceived ease of use. On the other hand, socioeconomic variables demonstrate that neither age nor gender moderates the relationship between digital literacy and online purchase intention; in short, age and gender do not condition the intention of the Internet user.

Objectives: This study aimed to investigate the digital literacy and major satisfaction levels of dental hygiene students and identify the interrelationships between them as well as the factors related to major satisfaction. Methods: An online survey was using a structured questionnaire was conducted with 223 dental hygiene students. Digital literacy and major satisfaction were measured using a 5-point Likert scale, and correlation and multiple regression analyses were performed. Results: The participants' digital literacy averaged 3.87 points, and their major satisfaction averaged 3.82 points. The digital literacy factor related to major satisfaction was critical thinking skills (β=0.747, p<0.001). This indicates that the higher the critical thinking skills, the higher the major satisfaction. The explanatory power of the model was 63.7%. Conclusions: Critical thinking skills as a factor of digital literacy were found to influence dental hygiene students' major satisfaction, suggesting that a curriculum that can increase critical thinking can improve major satisfaction.

This study was designed to analyze the relationship among the motivations for the use of digital devices, attitudes toward the use of digital devices and performance resulting from the use of digital devices in middle-aged and elderly groups by using a path analysis. For an empirical analysis, the 2018 Survey on the Digital Divide by the National Information Society Agency was referenced, analyzing the data of 1,664 people, selected through listwise deletion from total 2,303 people aged 55 or over. A close examination of how measuring variables reflect potential variables (motivations for, attitudes toward and performance resulting from the use of digital devices) showed a significance of 0.001, which suggests that each individual measuring variable does reflect the potential variables. Evaluation of the pathway factors of the structural model from the motivations for the use of digital devices to the attitudes toward the use of digital devices (β=0.847) and from the attitudes toward the use of digital devices to the performance resulting from the use of digital devices (β= 0.745) revealed significant statistical effects. The results of this study suggest that the motivations for the use of digital devices does not directly enhance the digital device use performance, but that it can improve the attitudes toward the use of digital devices, which can in turn increase the performance resulting from the use of digital devices. The analysis holds significance that it has presented practical and policy implications.
