In MR functional imaging, it is shown that the signal change during photic activation is composed of two terms, i.e. the inflow effect and the susceptibility effect. Relatively the inflow effect affects the data obtained by CGE on the condition of short $T_E$(15ms) and large $\alpha$(90degree). The susceptibility effect, however, mainly contributes to the data on the condition of large $T_E$(35ms) and small $\alpha$(30degree). In this apper, we will discriminate the susceptibility effect for the intermingled data affected both flow effect and susceptibility effect. Finally susceptibility only functional imaging is proposed by using TRFGE.

Objective: This study aimed to investigate the effect of parent- teacher communication on childcare teacher's job stress and turnover intention. This study also examined if the level of active stress coping used functions as a moderator in relationships among parent-teacher communication, childcare teacher's job stress, and their turnover intention. Methods: To achieve this, this study used data from 223 surveys from childcare teachers and analyzed the data with SEM and multi-group SEM analysis methods. Results: First, parent-childcare teacher communication influenced the teacher's turover intention through job stress. Second, the effect of parent-childcare teacher communication on job stress was not found in the higher-level of the active stress coping group. This was different from the significant effect in the lower-level of the active stress coping group. Also, parent-childcare teacher communication influenced teacher's turnover intention through job stress in the lower-level of the active stress coping group. In contrast, the mediation effect was not shown in the higher group. Conclusion/Implications: The results of this study show the effect of parent-childcare teacher communication on teacher's job stress and their turnover intention. Also, this study shows that the level of active stress coping could moderate the relationship among parent-childcare teacher communication, teacher's job stress, and their turnover intention.

In this study, we investigated the effect of users' emoticon usage on their satisfaction with image making and self-expression in MIM communication. We defined internal attraction, social appeal, and communication ability as personal image making factors due to the use of emoticons in MIM communication. And we defined the research hypotheses based on the definition of intimacy, openness, and social reality as relational image making factors. In MIM communication, we analyzed the questionnaire about emoticon users. As a result, emoticon usage was found to have a positive and significant effect on self-expression in relation image making rather than personal image making. The study implies that the use of emoticons can lead to image making in MIM communication and satisfy the satisfaction of self expression.

This study identifies correlations between the use of media devices, communication ability, and executive function difficulties for third grade students, as well as investigates the moderating effect of a child's communication ability. Data from the 10th (2017) Panel Study on Korean Children [PSKC] was employed (N=557). Descriptive statistics, Pearson's correlation and hierarchical regression were used along with SPSS 25.0(IBM Co., Armonk, NY, USA). The results were as follows. First, the executive function difficulties in the third-grade showed a significant positive correlation with media device use. While also, showing a negative correlation with a child's communication ability. Media devices use and communication ability has a significant negative correlation. Second, a child's communication ability has a moderating effect in relation to the use of media devices and executive function difficulties. The difficulty of executive function showed a reciprocal increase to a child's use of media devices and indicated a discriminatory effect of a child's communication ability. In conclusion, this study shows that communication ability is important as a personal factor for children who control the negative effects of media devices. Therefore, it is necessary to provide and support an environment for the development of a child's communication ability.

한국형 고속철도인 KTX가 2004년 개통된 이후, 우리나라에서도 철도의 이용도가 급증했다. 개선되는 철도 기술과 함께, 예전에 비해 열차의 속도 또한 빠르게 발전하였다. 그러나 이러한 열차속도의 발전은 철도 통신에 있어서 열차 속도 증가로 인한 도플러 효과와 이에 대한 보상이라는 새로운 이슈를 제기하였다. 이러한 도플러 효과는 통신하는 대상의 속도에 따라 주파수 변이를 일으키며, 이는 신호의 왜곡으로 이어져, 통신성능에 좋지 않은 영향을 미칠 수 있다. 따라서, 이러한 도플러 효과에 대한 문제는 철도 무선 통신에 있어서, 반드시 해결해야 할 문제이다. 본 논문에서는 앞으로 발생할 고속의 철도 통신에서 발생하는 도플러 효과와 발생하는 도플러 효과에 대한 보상기법 및 이에 대한 모의실험 결과를 소개하고자 한다.
