With the importance and necessity of using AI in the field of education, this study aims to explore elementary school teachers' perceptions of using Artificial Intelligence (AI) in mathematics education. For this purpose, we conducted a survey using a 5-point Likert scale with 161 elementary school teachers and analyzed their perceptions of mathematics education with AI via four categories (i.e., Attitude of using AI, AI for teaching mathematics, AI for learning mathematics, and AI for assessing mathematics performance). As a result, elementary school teachers displayed positive perceptions of the usefulness of AI applications to teaching, learning, and assessment of mathematics. Specifically, they strongly agreed that AI could assist personalized teaching and learning, supplement prerequisite learning, and analyze the results of assessment. They also agreed that AI in mathematics education would not replace the teacher's role. The results of this study also showed that the teachers exhibited diverse perceptions ranging from negative to neutral to positive. The teachers reported that they were less confident and prepared to teach mathematics using AI, with significant differences in their perceptions depending on whether they enacted mathematics lessons with AI or received professional training courses related to AI. We discuss the implications for the role of teachers and pedagogical supports to effectively utilize AI in mathematics education.

The purpose of this study is to analyze the case in which we can identify how the SoC of Practical training teachers about the instructional media changes and why these change appears during the child care practice when we assumpt that for Practical training teachers to use the instructional media is that they participate in change during child care practice. In case A, the SoC moves from Stage 0 to Stage 1, Stage 6. In case B, the SoC moves from Stage 0 to Stage 2. In case C and D, the SoC of the Practical Training Teachers are not changed. Above this, we identify the SoC of Practical training teachers. Case A and B change the SoC, but Case C and D does not change the SoC after child care practice. We identify that the reason why there are differences is that according to (1) the training of the perception of practical training teachers, curriculum, knowledge related to instructional media before child care practice, and (2) time, the SoC of practical training teachers about instructional media is changed. In the end, we make a suggestion for the following research. First, a comparative study will be made of other students of the department for child care in the same college or other college. Second, we need to make a study for analyzing SoC profile after supporting instructional assistances.

Purpose: This study was conducted to investigate ICU nurses' perceptions of communication difficulties, the importance of and satisfaction with communication with doctors, other nurses, patients, and family, as well as to explore communication barrier with patient families. Methods: Investigators developed a 15-item communication perception questionnaire and 58-item communication barrier questionnaire. Communication barrier included 4 domains: nurses, family, environment, and patient condition. A total of 151 ICU nurses with a minimum of one year of ICU experience participated. Results: ICU patients ($3.38{\pm}0.73$) were the most difficult group to communicate with, followed by family ($3.32{\pm}0.72$), senior nurses ($3.25{\pm}0.74$), doctors ($3.21{\pm}0.68$), and nurse colleagues ($2.64{\pm}0.73$). Doctors ($4.61{\pm}0.53$) were the most important group to communicate with, followed by nurse colleagues ($4.52{\pm}0.54$), patients ($4.49{\pm}0.58$), senior nurses ($4.44{\pm}0.55$), and family ($4.43{\pm}0.61$). Satisfaction with communication was the highest with colleague nurses ($3.60{\pm}0.68$), then senior nurses ($3.37{\pm}0.74$), family ($3.18{\pm}0.71$), patients ($3.09{\pm}0.75$), and doctors ($3.06{\pm}0.83$).The total score of the communication barrier was $2.83{\pm}0.52$, where each domain was scored as follows: patient condition $3.13{\pm}0.74$, nurses $2.83{\pm}0.60$, environment $2.81{\pm}0.66$, and family $2.76{\pm}0.57$. The ICU nurses reported that communication was difficult due to 'sudden deterioration in the patient's condition', 'being too busy', 'a noisy environment', and 'information not being shared between family members.' Significant differences were noted by age, clinical experience, and marital status of nurse respondents. Conclusion: The findings indicated that development of a protocol on communication between nurses and doctors as well as development of an educational program on communication skills are necessary.

The purpose of this study was to analyze the performance of the Daegu Happiness Competency Education Program. It was confirmed that students, parents, teachers, and education professions are aware of the middle and higher level of education for happiness in Daegu in terms of the formation and operation of the curriculum. There is no significant difference between students and parents in terms of average value, and teachers' perception level is relatively high, which is understandable in that teachers are the subjects of the curriculum organization and operation. In addition, there was no statistically significant difference between the parents and the school level, but there were significant differences between students and teachers. In particular, students' and teachers' perceptions were lowered as the number of schools increased, unlike the predictions. They showed the lowest results in the special schools, autonomous schools and special schools. The reason for this is that Daegu Happiness Competency Education was implemented in 2014, and it was because there was little room to recognize and accept the new curriculum due to the burden of college entrance examination or employment. In the future, it will naturally improve as the education process is settled, but here we can find suggestions for the establishment of Daegu Happiness Competency Education.

This study investigated the status of the wh-island constraint in Seoul Korean. The syntactic movement of a wh-phrase out of an embedded sentence so as to have wide scope at LF is known to be invalid as it violates the wh-island constraint, but there have been studies in which such a movement was possible when the sentence is read with a wh-intonation. We conducted perceptual tests in which subjects were asked to select an answer after listening to each of the four types of interrogative sentences. Three of them were with 'Nugu-leul', which is an accusative form of the wh-phrase 'who' as well as an indefinite form. The fourth sentence contained the name of a person. 'Nugu-leul' and the noun were positioned in the same embedded sentence to see whether the subjects accepted a matrix scope interpretation of the wh-phrases. Response time was transformed to normalized log response time and checked to find any differences in the time taken to select the answers depending on different types of interrogative sentences. The results showed the subjects had a definite preference for the matrix scope interpretation for the sentences with a wh-intonation. The response time required to select the matrix scope interpretation was longer than for any other type of interrogative sentence. We concluded that the wh-island constraint in Seoul Korean is weak.

This study aims to examine how old people think about 'dignifiable aging'. For the study, the authors have tried to understand and analyze of old people's view on 'classy and gracious aging' through their life experiences. The study focuses on the questions of 'how the participants experience aging', 'how they understand well, classy and successful aging and 'how they explain their ideas of the aging, then analyzes their ideas as types of 'within cases' as well as 'inter cases'. Indepth interview has employed as main methodology of data collection with the analysis of concerned written documents such as on-line and off-line essays as secondary data. The collected data had been basically sorted and analyzed by sorting commonimity and differences. Then they have been classified into the thems that indicate meanings and forms of 'dignified aging': 'ageless mind', 'happiness determined by one's mind', 'responsibility on family', 'desire for learning and social activities'. These meaning-units are added up to the main meaning of '(fullfilled) satisfaction through life-values' mediated by 'acceptance and acknowledgement', 'efforts', 'others' gaze', 'dreams and hopes', '(fullfilled) Satisfaction through life-values' can be achieved by 'sharing with others'. An interesting fact is that the meaning-units can be devided into two groups: 'the real life is the ideal life' which explains the actualization of the ideal in the daily life and 'life, conflict, the ideal' in which the real and the ideal are parellel with constant conflicts. In the conclusion, some implications and suggestions derived from the analysis are described from the v iew of social welfare.

The purpose of this study was to examine the effect of Small-Scale Chemistry(SSC) lab program on the academic self-efficacy and the science-related affective domain of 11th grade science-majored students. For this study, a SSC lab program was developed on the basis of analyzing the textbook of high school chemistry I in the 7th curriculum, and the experimental group was received SSC experiment lessons(SSC group), and the comparison group was received traditional experiment lessons. After students were grouped high and low level according to the students' prior science achievement score, the differences between the two groups were investigated using 2-way ANCOVA. From the result of this study, we found that the SSC lab program was more effective than the traditional Large-Scale lab program based on the textbook in academic self-efficacy. And the scores of interest toward science-related careers and creativity for the SSC group, which are subcategories of science-related affective domain were significantly higher than those for the comparison group. In students' perceptions on the SSC lab program, majority of students thought that the SSC lab program was convenient, effective and interesting.

The purpose of this study is to investigate how storytelling is embodied in the Mathematics I textbooks for first grade high school students in the 2009 revised curriculum and the perception of secondary math teachers and students of those books. Furthermore, in order to have some implications on newly ongoing textbook development, this thesis sets up the following goals for inquiry into the effect on storytelling. First, are there any noticeable differences among the 10 types of mathematics I textbooks for high school first graders in the 2009 revised curriculum? Second, what do teachers and students think of textbooks which apply storytelling techniques? The results are as follows. The frequency of storytelling types that appeared in the textbooks is as follows: real-life connection type and inter-scholarship type take up 47.55% and 24.51% respectively, followed by decision-making type with 10.52%, math history type with 10.17% and tool-using type with 7.05%. Within the contents, math history type showed up on reading material from every textbook. And it is worth considering that real-life-connection type has the most various topics and is mainly for arousing interest and checking up on some concepts. However, inter-scholarship type is usually related to science, and decision-making type is included for error analysis and tool-using type for reading materials about math programs. The results of this study suggest that many of the teachers who participated showed some kind of understanding of storytelling but there were not many who are actually incorporating that into their own classes. It is also essential that we develop textbooks that are effective for storytelling classes, hold regular symposiums as well as teacher training, and create tools for proper assessment. Furthermore, students think that textbooks based on storytelling would have positive effects as long as they are supported by enough time, a sufficient number of classes and tests with validity.

To investigate the influence of hand cream of domestic and foreign brands on the purchase tendency, a survey was conducted on hand cream application, purchase tendency, and perception of 105 women in a metropolitan area. Market research was then conducted to compare the hand cream cost, quantity, and total substance, and the hand creams were sorted according to high-price and low-price, and foreign brand and domestic brand, and a clinical demonstration was conducted by back-hand application on 17 recipients to analyze the moisture and skin oil differences and the moisture endurance. As a result, the percentage of subjects who perceived that the price and brand of hand cream affects the quality was higher than those who did not, and the hand cream prize per 1mg (g) varied as much as fourfold among the high-price and low-price, and among foreign and domestic brands. The result of the total substance comparison, glycerin the moisturizer and cetearyl alcohol the skin conditioner were included in all hand creams. As a result of the clinical demonstration, the difference in moisture and skin oil difference and moisture endurance between the high-price and low-price and foreign brand did not show a statistically significant difference. These results show that there are no relationships between skin moisture and sebeum of the brand. Therefore, considering that hand cream is a highly consumptive product that is used multiple times on a daily basis, these results might provide fundamental data that could contribute to the increase in hand cream product quality by determining the consumers' needs.
