This study attempted to determine the effects of a context-based drawing task on the language expression of a severe Wernicke's and Broca's aphasic. The subjects in this study showed a poor auditory comprehension and naming performance. They also showed paraphasia and perseveration. This study focused on improving language expression by a drawing task based on conversation at hand. Ten target words were chosen which were easily drawnable and familiar to the subjects. The results showed that the context-based drawing task was effective on improving the subjects' confrontation naming ability and expressive language ability in terms of explanation of sentences. In addition, the Broca's aphasic showed improved naming ability when the contextual cues were given and he was supposed to spontaneously name words.

사람은 개인마다 선호색이 다르다. 때문에 색채를 통해서 개인의 성향을 분석하기도 한다. 일반적으로 난색은 밝고 따뜻한 색으로 활기와 적극성을 띄며 한색은 차갑고 냉정함, 차분함 등과 같은 의미를 지닌다. 이러한 색채가 가지는 의미는 개인의 환경, 성향, 성별, 연령 등에 따라 다르게 나타난다. 색채 선호는 일반적으로 개인이 색채에 대해 좋아하는 정도를 의미하는 것으로 개인의 성향이나 상황, 경험 등에 의해 형성된 지극히 개인적인 색을 말한다. 본 논문에서는 색채 선호를 분석하는 심리 검사 CRR와 Flood Fill 알고리즘을 적용하여 그림에 색채를 채워서 주조색과, 보조색을 각각 Decision Tree에 적용한다. Decision Tree의 결과를 기반으로 데이터베이스와 연동하여 개인의 심리 상태를 분석할 수 있는 방법을 제안한다.

This study presents an out-of-school problem-solving lesson we designed for American Indian students using a culturally relevant STEM topic. The lesson was titled "Shelter Design for Severe Weather Conditions." This shelter design lesson was developed based on an engineering design allowing us to integrate STEM topics within a traditional indigenous house-building context. This problem context was used to encourage students to apply their prior knowledge, experience, and community/cultural practice to solve problems. We implemented the lesson at a summer program on an American Indian reservation. Using the lesson, this study explores how American Indian students use cultural knowledge and experience to solve a STEM problem. We collected student data through pre- and post-STEM content knowledge tests, drawings and explanations of shelter models on the students' group worksheets, and classroom observations. We used interpretive and inductive methods to analyze the data. This study demonstrates that our culturally relevant, STEM problem-solving lesson helped the American Indian students solve a complex, real-world problem. This study examines how students' prior experiences and cultural knowledge affect their problem-solving strategies. Our findings have implications for further research on designing problem-solving lessons with culturally relevant STEM topics for students from historically marginalized populations.

In simple and multiple regression, there is a difference in the meaning of regression coefficients, and not only are the estimates of regression coefficients different, but they also have different signs. Understanding the relative contribution of explanatory variables in a regression model is an important part of regression analysis. In a standardized regression model, the regression coefficient can be interpreted as the change in the response variable with respect to the standard deviation when the explanatory variable increases by the standard deviation in a situation where the values of the explanatory variables other than the corresponding explanatory variable are fixed. However, the size of the standardized regression coefficient is not a proper measure of the relative importance of each explanatory variable. In this paper, the estimator of the regression coefficient in multiple regression is expressed as a function of the correlation coefficient and the coefficient of determination. Furthermore, it is considered in terms of the effect of an additional explanatory variable and additional increase in the coefficient of determination. We also explore the relationship between estimates of regression coefficients and correlation coefficients in various plots. These results are specifically applied when there are two explanatory variables.

Much of our lives are closely related to artificial intelligence, and society is changing more rapidly. Reflecting this era, the need for artificial intelligence education has emerged and various learning methods have been proposed, but guidance on artificial intelligence teaching and learning activities for lower grades elementary school students is insufficient. Therefore, in this study, the data collection education program for the lower grades of elementary school was developed based on the contents standards of the Korea Foundation for the Advancement of Science & Creativity. Focusing on the principles of artificial intelligence and the detailed data area of the utilization area, the focus was on expressing numbers and letters in various ways, such as colors and pictures, and finding various types of data in life to learn the principles of artificial intelligence. Through this program, it is expected that lower-grade elementary school students will be able to understand the importance of data collection in artificial intelligence through the process of knowing about data and collecting sound, picture, and text data.

Given the importance of early experience in algebraic thinking, we designed six consecutive lessons in which $4^{th}$ graders were encouraged to recognize patterns in the process of finding the relationships between two quantities and to represent a given problem with various mathematical models. The results showed that students were able to recognize patterns through concrete activities with manipulative materials and employ various mathematical models to represent a given problem situation. While students were able to represent a problem situation with algebraic expressions, they had difficulties in using the equal sign and letters for the unknown value while they attempted to generalize a pattern. This paper concludes with some implications on how to connect algebraic thinking with students' arithmetic or informal thinking in a meaningful way, and how to approach algebra at the elementary school level.

Recently, Chat GPT artificial intelligence (AI) is of keen interest to all governments, companies, and military sectors around the world. In the existing era of literacy AI, it has entered an era in which communication with humans is possible with generative AI that creates words, writings, and pictures. Due to the complexity of the current laws and ordinances issued during the recent national crisis in Korea and the ambiguity of the timing of application of laws and ordinances, the golden time of situational measures was often missed. For these reasons, it was not able to respond properly to every major disaster and military conflict with North Korea. Therefore, the purpose of this study was to revise the National Crisis Management Basic Act, which can act as a national tower in the event of a national crisis, and to promote artificial intelligence governance by linking artificial intelligence technology with the civil, government, military, and police.

Uigue(儀軌) is the report of court events, and its contents are very detailed and crucial as it is even called as the flower of written culture. Thus, many research theses about Uigue have been accumulated in academic circles so far, and easy books about Uigue targeting ordinary people have also been published. However, Uigue has not been used actively in educational circles yet. From now on, we should develop and induce ways to use Uigue actively in educational spots in order to let students who will lead our future have pride in our culture and know about the superiority of our court music culture. Especially when court music culture is taught in the sector of Korean traditional music education, it is beneficial to use Uigue. Since most of the court music repertory is slow and magnificent, if court music itself is exposed beforehand, it might give them an impression that it is "unexciting and boring". Therefore, this study gropes for teaching methods to 'show' court music culture first through various visual aids contained in Uigue. In other words, it examines how the instrument images, band images, dance images, or concert stages contained in Uigue can be used as teaching materials. Except for the materials selected in this article, there are plenty of teaching materials for court music culture in Uigue. Furthermore, it would be even better if not just Uigue but Oryeseo (五禮書), Akseo(樂書), Dobyeong(圖屛), and Gwanchan Akbo(樂譜) can be added to widen its range for more multilateral court music culture education. And if at the educational spots, showing classic court music culture is accompanied with listening to court music through various materials of court music and dance, we can expect even better educational effects from it.
