This study is to develop a valid and reliable instrument for measuring students' creative engineering problem solving propensity. The creative engineering problem solving is operationally defined in this study as a creative problem solving skill in an engineering context. To develop the instrument, first we define seven common constructs between engineering problem solving skill and creative problem solving skill through an intensive literature review; motivation, context, personal character, engineering design, engienering habits of mind, understandings of engineering and engineers, communication skill, and collaboration skill. Based on the seven constructs and the face validity test conducted by two in-service science teachers and 4 experts in science education research, 40 preliminary items were developed. Then the preliminary instrument was implemented in a science gifted highschool to measure the reliability of the instrument. From the 40 items, 34 items were selected through the initial reliability test by Cronbach's ${\alpha}$(>.75). Finally through the three times of factor analysis process, 28 items in five construct categories were selected; motivation (3 items), engineering design (6 items), engineering habits of mind (9 items), understandings of engineering and engineers (4 items), communication and collaboration skill (6 items). The factor analysis result showed that the reliability of each construct category was between .733 to .892., meaning that the instrument is reliable in terms of the higher structural validity (each item is categorized in an appropriate construct category). We expect that the creative engineering problem solving propensity instrument developed in this study can be used in various contexts for STEAM education research as a reliable and valid instrument.

The purpose of this study was to examine (1) the influence of the word-prediction function on the sentence generation speed and (2) the necessity, convenience, and satisfaction of the word-prediction function of the AAC keyboard. A total of 10 adults with cerebral palsy participated and the word-prediction function of the Korean high-tech AAC device called "MyTalkie Smart" keyboard was used for this study. Participants were required to generate sentence as voice outputs using a word-prediction function and letters direct-input function respectively, then they were required to evaluate the necessity, convenience, and satisfaction using a five-point Likert scale. Other user requirements were examined using a free feedback. The results of this study presented that the sentence generation speeds were faster when participants used a word-prediction function than using a letters direct-input function. However, there was no statistically significant difference between these two input methods, and it might be due to the lack of time to practice the new device. Participants showed positive responses for the necessity, convenience, and satisfaction of the word-prediction function.

The present study employed a pretest-posttest quasi-experimental design to evaluate the effectiveness of a teacher education program for child care teachers. Twenty-seven teachers were randomly assigned to intervention and control groups with 12 and 17 teachers in each group. Teachers in the intervention group participated in the program. After termination of the program, differences between pre- and post-tests were examined in regards to teachers' emotional regulation, efficacy, parent-teacher communication and job satisfaction. There were four major findings. First, self-reported teachers'emotional regulation, teachers'efficacy and job satisfaction were significantly improved in the intervention group, but not in the control group. Second, parent-teacher communication difficulty was significantly reduced in the intervention group, but not in the control group. These findings emphasize the importance of the teachers' positive characteristics in improving the outcome of preschoolers.

The purpose of this study is to suggest the assessment method for PO6(teamwork) and PO7(communication skill), one of the most important assessment items in engineering accreditation. In this paper, we used the assessment criteria of Rubric, to empirically measure the teamwork and communication skill. Teamwork and communication skill (PO6, PO7) are the most critical social competences in modern society. Numerous studies on education showed that teamwork and communication skill can be enhanced through learning. We, therefore, need to investigate teamwork and communication skill in terms of education. However, research on the assessment method of the engineering accreditation, based on educational view is scarce. In this study, we suggest the assessment criteria of Rubric for PO6 and PO7 with the perspective of the education. We also tried to apply the developed criteria to the related subjects.

The purpose of this study is figure out secondary education undergraduates' communication patterns and perceptions of use in KAKAOTALK, one of the most frequently used Social Network Service(SNS). The mixed method research was conducted of survey about 86 students and in-depth interview 10 of them. The chief implication of research showed that it has been firstly functioning them to sustain public and private network and to be an universal tool of expression their opinion, idea, themselves, however, they still regard face-to-face communication important. Secondly, they think that KAKAOTALK is a part of their everyday lives and regarded a communication space to freely express themselves and to adjust and manage their image. Thirdly, they psychologically solved their loneliness and were encouraged, moreover, the contents of communication were different according to usd of public or private team chat room. It needs a follow-up study comparatively to analyze other generation's cognitive psychological values in SNS and to suggest digital culture literacy guideline.

Purpose The aim of this study was to identify the differences and relations among the communication competence, job stress and job satisfaction of clinical nurses. Method The participants included 209 nurses who worked at general hospitals in metropolitan Seoul and Gyenggi province. The instruments used for this study were the revised version of the Global Interpersonal Communication Competence Scale(GICC), the Job Stress Scale, and the Job Satisfaction Scale. Data were analyzed using frequencies, t-test, ANOVA, Spearman rank-order correlation coefficient with the SPSS 16.0 program. Result The results of this study were as follows: The mean score for communication competence was 3.30(${\pm}0.43$). For job stress and job satisfaction's mean score were 2.90(${\pm}0.33$) and 3.01(${\pm}0.30$). Significant negative correlation were found between the communication competence and job stress of clinical nurse(r=-.247, p<.001). Significant positive correlation between the communication competence and Job Satisfaction of clinical nurse(r=.248, p<.001) was also found. Conclusion The findings of this study support the importance of the communication competence of clinical nurses for efficient human resource management. Studies for developing programs to facilitate communication competence of clinical nurses are highly recommended.

The purpose of this study was to investigate the influence of maternal post-natal depression on children's communication competence, maternal self-efficacy and parenting style. The data on 1,438 pairs of children and their mothers were provided by The Korean Children Panel Study (KCPS). Mothers were assessed by K6(Kessler et al., 2002), The Pearlin Self Efficacy Scale(Pearlin et al., 1981), and The Parental Style Questionnaire(Bornstein, et al., 1996). Children's communication competence was assessed by K-ASQ. The collected data were analyzed with t-test and path analysis. The major results of this study were as follows : (1) Post-natal maternal depression was not directly associated with the children's communication competence. (2) Post-natal maternal depression indirectly influenced the children's communication competence via maternal self-efficacy and the parenting style. The results of this study suggest that post-natal depression within 1 year will not have an effect on the children's communication competence directly, but will indirectly influence it through maternal self-efficacy and the parenting style when the children are 2 years old.

In this paper, we propose to develop a diagnosis tool for measuring digital competence for university student. To this end, 223 students participated for the survey research. Based on the survey by 6 domain and 40 questions, 6 factors and 18 questions for digital competence measurement were drawn throughout the factors analysis. The results of the confirmatory factor analysis showed the fact that 6 factors and 18 questions that satisfied the model-fit indexes statistically were finally confirmed. And the developed tool demonstrated good results in reliability and validity verification, which were suitable for measuring digital competence for university students. The developed measurement tool of digital competence for university students consisted of 6 sub-components such digital device operation, communication and collaboration, information searching, processing, and management, problem solving and learning, security, digital ethics. The digital competence measuring tool developed in this study is expected to be used to identify the current level of competences for university student, and to enhance their own digital competences through educational supports.
