Purpose: The purpose of this study is to develop a realistic illustration using watercolors on a complete airway obstruction maneuver that is at an appropriate level for elementary school students from the first grade through the third. The illustration is a series of cuts divided into specific frames designed to illustrate the method to be followed in an action or a practical skill that would otherwise be too difficult to explain in written form. Methods: The fundamental theory of the Jeong In-Sung's instruction learning program based on the WEB to construct an appropriate site of instruction learning was used after modification. In this study analysis, design, and production stages were realized. Results: 1. In Stage 1, impressions of the illustration, in sketch form, were received. In Stage 2, results of impressions from a modified illustration were received. After an appropriate level of understanding and accuracy in the practical steps for emergency maneuvers were achieved the illustrations entering Stage 3 and color was added to the sketches. 2. In Stage 3, the illustration was completed by adding color to the contents for the practical steps in the complete airway obstruction maneuver. 3. For composition evaluation, a result of 100% appropriateness was obtained for both items of harmony between illustration and subject being studied and sufficiency in quantity of illustrations. Also high results for appropriateness in items such as clarity, creating interest, illustration size, and tone preference as related to content were achieved and thus completed the production stages. Conclusion: The Complete Airway Obstruction Maneuver Illustration developed specifically for the characteristics and cognitive level of elementary school students grade 1 through grade 3 was appropriate for teaching and learning. There is a need for future research on developed illustrations aimed at elementary school students grade 1 through 3 on the complete airway obstruction maneuver. There is also a need for continued effort in developing certified evaluating tools that can judge the suitability of illustrations and developing illustrations related to emergency maneuvers for various subjects and appropriate for learner level.

The purpose of this study is to develop a web-based database system to manage effectively data collected to evaluate program learning outcomes (PO) in a nursing school. The database management system (DBMS) was developed using a software development life cycle method: Analysis, Design, Implementation, and Evaluation. The demands for the content and system of users were collected. The system structure, database using an entity-relationship modeling, and user interface were designed based on the demands. The designed DBMS was created using GWT, Java and Apache HTTP server. The expert group and users evaluated the implemented DBMS. Problems derived from them were modified. The average of end-user computing satisfaction evaluated by 8 nursing faculty and 5 teaching assistants was 4.14 (SD =.44). The web-based PO DBMS makes it possible for nursing faculty members to access and use much of the information needed for analysis and decision-making.

Although student research programs have been implemented worldwide, research programs during premedical school have unique characteristics. The purpose of this study is to evaluate factors that influence the effects of premedical school research programs. Eighty second-year premedical students at Pusan National University were included in the study. Effect elements and influential factors were extracted through reference reviews and in-depth individual interviews. A Likert scale questionnaire was developed using the extracted elements and factors, and Cronbach's alpha coefficient was used to analyze the reliability of the survey. The mean value and the standard deviation for each question were calculated to evaluate education effectiveness and learning satisfaction, and the influence of each factor on effect was analyzed using correlation analysis. Students' research skills and knowledge were improved in the short term; however, interest in research or in a career as a researcher did not increase. Student interest, participation, and contributions were important factors. Among professors, passion, considerateness, and teaching method including the level of lesson were influential factors. Implementation of curriculum and support and guidance were influential as well, whereas evaluation system was not a factor. To improve student research programs, several factors that influence education effectiveness and learning satisfaction should be considered.

As the importance of technology in education has increased, TPACK research has been actively conducted to promote the use of technology in class. However, due to the functional limitations of technology, the pre-service teacher had difficulty in using technology in class. Therefore, in this study, we have been studying the introduction of the programming language as a technology tool of TPACK. Using design-based research as a research method, we repeatedly developed an educational program, applied to pre-service teachers, and evaluated the effectiveness of the program. In the first study, pre-service teachers had difficulties in programming learning. To solve this problem, programming-based instruction and curriculum analysis were supplemented by educational programs. In the second study, pre-service teachers felt difficulty in using programming in teaching-learning, thus improving instruction design and reflection. The third study enhanced the programming development environment search to supplement programming learning and utilization.

here are many cases that take a software education as a required course for non-major students in university curriculums. However, non-major students are experiencing various difficulties in the process of learning programming languages, and there is also the opposite opinion in terms of their effectiveness. In this study, we developed a design based software education model (DBSEM) and curriculum to solve these problems and applied it to undergraduate non-undergraduate students for the last 8 years. In the proposed method, we provide a specialized educational tool such as 'block-based programming tool', but developed 'core module' and 'concept learning module' for computational thinking and applied 'prototype design module' and coding strategy based on it. As a result, non-major undergraduates could easily learn block-based scripting tools and acquire core concepts of computational thinking.
