The purpose of this study was to propose a theoretical model for an integrated medical humanities curriculum based on a STEAM (science, technology, engineering, arts, and mathematics) education framework and to provide a guideline for curriculum integration. Three dimensions of integrated curriculum development are competencies, core contents, and elements of integration. Competencies imply the purpose of the medical humanities of a medical school and the exit outcomes of the curriculum. Core contents imply the goals and objectives of the curriculum. We compared the goals and themes of the medical humanities with core attributes of professionalism. Four elements of integration were proposed: units (cases, problem activities, core contents, disciplines/subjects), types (multidisciplinary, interdisciplinary, transdisciplinary), contexts of integration (life cycle of patients, scope of society), and stages of student development (from student to doctor). It is expected that this theoretical model for an integrated medical humanities curriculum can be used as a guideline for curriculum development and an evaluation criterion for instructional designers and subject matter experts.

Science, Mathematics, Engineering, and Technology (STEM) integrated education has been spotlighted as a new approach for promoting students' conceptual understanding and supporting their future career in STEM field. There is increasing evidence of the positive impact of using a whole design process that can be an example of STEM integrated activities to improve students' conceptual understanding and problem solving skills. However, there is a lack of information on how teachers should accomplish science and engineering integration activities in their classroom and what process they should pay attention. To answer this question, we research the relationship between an design process and students' conceptual understanding using an engineering design activity, called 'Save the Penguins', and study on how each step in an engineering design process in this activity enhance students' conceptual knowledge in science. We found that testing their prototypes and discussing with their peers were the most important process for students to understand and apply science concept for their design, even though the whole engineering design process (demonstration about radiation, discussion about examples in our lives, and testing and reviewing their prototypes, and making final design) helps the students understand the scientific concepts.

STEAM education, which was introduced to address many of the issues raised in science and technology education, has had a profound impact on the field of education over the past 13 years. This study aims to systematically analyze the research trends of STEAM education integrated with mathematics from 2010 to 2022 and to provide implications for future STEAM education. To this end, 89 articles published in domestic KCI journals were collected and analyzed. The results showed that more than half of the STEAM studies were related to the development and application of STEAM programs. The next most frequent studies were related to current state and improvement oaf STEAM education, followed by curriculum and textbook analysis, and by teacher education and teacher competencies. Students' and teachers' perceptions and attitudes toward STEAM education were addressed in only a few papers.

For admitting a hard real-time connection to an ATM network, it is required that the end-새둥 delays of cells belong-ing to the connection meet their deadlines without violating the guarantees already provided to the currently active connections. There are two kinds of methods to analyze the end-to-end delay in an ATM network. A decomposed method analyzes the worst case delay for each switch and then computes the total delay as the sum of the delays at individual switches. On the other hand, an integrated method analyzes all the switches involved in an inte-grated manner and derives the total delay directly. In this paper, we present an efficient and effecitive integrated method to compute the end-to-end delay. We evaluate the network performance under different system parameters and we compare the performance of the proposed method with the conventional decomposed and other integrated methods [1], [3], [5]-[9].

The objective of this study was to follow up changes in knowledge related to the mathematics education field work of preliminary early childhood teachers. The subjects of this research were 28 students who were taking mathematics education courses in early childhood education departments at various universities. This research ran for 15 weeks and was conducted through field work relating to mathematics education. The study collected data from pre-service teachers' knowledge, the diagram of concept, writing journals, interviews, and materials from the internet. Through this procedure, pre-service teachers' knowledge for mathematics education could later be expanded, ordered, and integrated. In addition, pre-service teachers not only understood the importance of contents and levels of lesson plans, but also learned how to utilize educational media to make effective lessons. Furthermore, pre-service teachers realized that the mathematical concepts of students could be expanded depending on the contents and methods of pre-service teachers' lesson plans and students could then apply these concepts into daily situations.

Large Midwest university faculty members proposed the Science and Technology Enhancement Program Project (STEP) to improve students' learning in the secondary mathematics classroom using modules of inquiry-based teaching. The purpose of this study was to determine the impact of the STEP Project on students' attitude toward mathematics. Hierarchical linear models (HLM) were used to evaluate the impact of the STEP Project. The sample group for the study was 130 ninth grade students enrolled in Integrated Algebra I in a large urban school district. The school was one of eight secondary schools that participated in the STEP Project. The classes in the treatment group were three of five classes ordered in terms of the highest, middle, and lowest mean GPA. The control group consisted of two other middle GPA classes. The classes had an average of 25 students. Teachers who previously had been involved in the STEP Project taught all treatment and control classes. The inquiry-based teaching activities provided by the project were confined to the treatment classes. The survey measuring students' attitudes toward mathematics were obtained for both groups of students. The inquiry-based teaching affected students' attitudes toward mathematics (p < 0.07, ES = 3.07). Especially, students who had preexisting low attitudes toward mathematics were significantly affected by treatment (p < 0.02, ES = 0.02), while the treatment positively affected African American students overall at p < 0.08 (ES = 0.58).

Creative thinking in education is a common assumption to be accomplish in this information age. Information education can contribute to build the ability to think creatively. The Author explored how information education conduces the creative thinking ability that is necessary to the development of independent and competent study for students themselves. The writer also expressed the integrated education makes students think synthetically and synthetic educational experience derives creative thinking. She based her arguments upon the theory of the psychology of memory and the Piaget's cognitive structure. To increase the effects of information education, it is necessary to integrate the curriculums and learning method of the information education and those of other areas of learning, i,e., languages, literatures, social sciences, sciences, mathematics, etc. Here, author asserted that the teaching of information skill within classroom curriculums for all subject areas can make the integrated effects on various classroom curriculums. On the basis of the findings of this study, the author recommended that every school needs to prepare enough books and other media for the students to drill information skill. Consequently, to build creative thinking ability for He students, librarians, classroom teachers and school principals who have influence on the information education, have to cooperate to initiate integrated information education for the student.

In this paper, we characterize Sobolev spaces $H^s(\mathbb{R}^n),\;s{\in}\mathbb{R}$ by the initial value of solutions of heat equation with a growth condition. By using an idea in its proof, we also discuss a stability problem for Cauchy functional equation in the Sobolev spaces.
