Objective : Aphasia interferes with communication between the patient and conversation partner. Adequate communication is essential not only for the patient but also for caregiver education and training Method : This study examined the benefits of parental education and group training in terms of improving the communication of six aphasic patients and their caregivers(family members). Caregiver education provided caregivers with information on stroke and aphasia, and group training was conducted according to the experimental learning cycle. Result : As a result, communication increased in terms of sending and receiving messages or interactive communication. Furthermore, the questionnaire analysis showed that caregivers learned more about aphasia and had confidence in using facilitation strategies. Conclusion : Giving educational opportunities to patients and caregivers promotes caregiver's knowledge and positively interacts.

This study is the qualitative study in order to discover a direction of field courses by analyzing what elementary school students observe or hypothesis in field courses. The purpose of it is to find any relevancy between the observations and hypotheses generated. The result of the study were as follows; First, most participants have observed mostly based on their vision due to the characteristic of field courses, and the observations of sedimentary layers were mainly generated on the rocks while most hypotheses were on geological structures. Secondly, according to observational descriptions the frequency of the comparative observation was high as well as the cases when two different types of observations were joined together. The last conclusion from this investigation is, according to the standard of observational types, the hypotheses combined with the interpretive observation and comparative observation had the greatest percentage. This shows that many participants tried to rationalize their thoughts by interpreting geological structures and comparing them with other people's cases as well. Scientific explanatory hypotheses were mainly found according to the standard of hypothetical types, which can be constructed that those participants tried to explain and apply established knowledge and preconception.

This study is a descriptive research study conducted to provide useful preliminary data that is helpful for self-initiated learning through a preference trend-based learning method by analyzing the personality types of university students in an area. In this study, the self-administered MBTI form $M^{(R)}$ test was performed on 695 students of 10 departments at K University, from September 18 to 22, 2017, using an automatic scoring system. Collected data was analyzed with descriptive statistics and Chi-square test, using the SPSS Win 22.0 Program, to sort the target students into one of 16 different personality types and examine psychological function and temperament by their personality. Differences in personality type preference by gender were as follows: for judging function, the male students had a strong preference for the T type (thinking type) while the female students showed a high preference for the F type (feeling type), and in the case of the pattern of behavior and lifestyle, the male students and the female students had a strong preference for the P type (perceiving type) and the J type (judging type), respectively. In addition, there were significant differences for each major and each department in personality type, psychological function and temperament. In conclusion, personality type was found to vary by gender, major and department. It would be necessary to develop a manual for learning methods reflecting individual preference.

Communication education research has focused on the effects of instructor characteristics on learning. It is necessary to consider student characteristics as well to develop an effective teaching strategy. The current study tries to classify students into multiple distinct groups depending on their personality traits and communication characteristics and investigates differences in effects of teacher characteristics between those groups. A survey on unversity students was conducted to collect data. A cluster analysis was carried out to identify distint sub-groups of respondents by their personality traits and communication characteristics. The analysis yielded two distinct groups. The two groups were named stable-reticent group', and 'neurotic-talkative group' respectivley. Series of multiple regression were carried out in order to investigate differences in the effects of instructor characteristics. The analyses found different patterns of effects between the two sub-groups. The findings suggest that it is necessary to adopt different communication styles and teaching strategies depending on student types.

This study was conducted to explore the characteristics of learner who showed free riding behavior in online collaborative learning. For this, 290 students from three universities in the metropolitan area were studied. The collected data are as follows. Learner characteristics are learning strategy, learning motivation, academic retardation behavior, and learning disposition. Interaction distinguished between frequency and type of message. Interaction levels were collected with frequency. The subjects with less than 5 interaction frequencies were defined as free-riding students. 43 students were classified as free riders. Learner characteristics were analyzed by cluster analysis. As a result, the learner characteristics were divided into five groups. All the free riding students belonged to 4 groups. The learner characteristics of 4 groups are as follows. First, the level of the learning strategy is very low. Second, learning motivation has a high tendency toward performance - oriented approach and high tendency to avoid performance. This tends to deliberately avoid learning. Third, the level of delayed behavior is high. This is deliberately putting off student activities. Fourth, learning tendency is high in academic anxiety, task value, self efficacy and learning belief are very low. This is a lack of confidence in learning.

This study was conducted to investigate the effects of DISC behavioral style on the knowledge and clinical performance of nursing students. The subjects of the study were nursing students in the fourth grade of university and the data collection period was from March 2015 to December 2016. The collected data were analyzed using SPSS 24.0. DISC behavioral style analysis showed that 10.6% were dominant, 33.8% were influence, and 48.5% were steadiness and 7.1% were conscientiousness. Knowledge score in accordance with the measured points of DISC behavioral style did not show differences in the first, but did show differences in the second and third. Conversely, clinical performance score in accordance with the measurement points of DISC behavioral style showed differences in the first, second and third.Knowledge and clinical performance scores revealed significant differences in the interactions between the groups, between measurement points and between groups and measurement points. As a result, DISC behavioral style of nursing college students vary, with each having merits and demerits. Therefore, it is necessary to provide an opportunity to understand these points and to develop merits in order to improve the learning outcomes of the curriculum.

The purpose of this study was to 1) explore the effectiveness of a college-level self-management (SM) course in improving a target behavior and reducing impulsivity, 2) investigate improvements in other non-target self-control behaviors(generalization of self-control), and 3) determine whether change in impulsivity could predict the generalization of self-control. A total of 128 College students who took the SM course were included. Participants completed the computerized delay-discounting task, self-report impulsiveness scale, and general self-control behavior questionnaire at the beginning and end of the course. After participants had defined their target behaviors, they self-monitored and recorded their behaviors everyday throughout the course. Results revealed that 63% of the participants successfully changed their target behaviors after the course. Although differing depending on the type of target behavior, thoes who successfully changed their target behaviors reported decreases in impulsivity and increases in other self-control behaviors such as physical exercise, healthy diet, study habits, and time management, after the course. Furthermore, the decrease of impulsivity significantly predicted the generalization of self-control in the exercise and diet groups. The results indicate that reduced impulsivity is related to improvements in a target behavior and general self-control behaviors in other spheres. Implications and limitations are also discussed.
