A process-centric simulation modeling method has been proposed to define a shipbuilding simulation model. Existing modeling methods have limitations for expressing various production information for a shipyard. The advanced process-centric modeling method proposed in this paper offers an improvement, effectively representing production information and constraints for a shipyard. To achieve this, a method and diagram components to define a process-centric simulation model in detail have been suggested. The modeling method can assign priorities when multiple products and facilities are assigned to the process. And layer concept was applied to express simulation model with hierarchical structure. To verify the effectiveness of the modeling method, comparative analysis has been performed and the actual shipbuilding process has been modeled using the proposed method. When a single facility was used for various purposes, we found that the proposed method was more advantageous than existing methods. As a result, it was possible to express constraints and flows that were difficult to identify with existing process-centric simulation modeling methods, and the methods were improved for use in shipyard production planning verification simulations.

Various studies have been conducted to identify the concept of creativity and enhance it effectively. Many advanced countries in the field of design have already expanded the scope of design education from specialized education to universal education and utilized such design education as a curriculum for promoting the creativity. Although education industry in China has been growing rapidly with the increase in the national income, the current educational contents have been mostly focused on the subjects/contents for an entrance examination, with little consideration of creativity promotion for children. Therefore, as an effort to promote creativity of Chinese children, the current study developed a design education program utilizing Chinese cultural contents and verified its educational effectiveness in terms of creativity promotion. The program was developed in the following process: 1) exploring the program development direction through an in-depth interview with parents; 2) deriving three lesson plans through an ideation session with some experts in art education for children; and 3) selecting a final lesson plan through experts/parents evaluation and developing a final textbook. A total of 10 children were educated with the developed textbook, and their levels of creativity before and after the education were comparatively evaluated using Torrance Tests of Creative Thinking (TTCT). The study results showed that the education program developed in the current study significantly affected the children's creativity, which would contribute to promoting the children's creativity, and also, developing a new creativity education program in the future. Additionally, it is expected that the research methods employed in this study, that is, developing a creativity promotion program using some cultural/local contents, could be usefully/widely applied in various fields of education.

The study was conducted to identify if the first-year program of science-focused school improved students' scientific core competency and science learning motivation. The first-year program of the science-focused school consisted of basic education in scientific inquiry, investigation, advanced experiment, and basic education in small research. There were a total of 262 participants in the program, and 169 students took three survey tests. Through the analysis of a group-based trajectory modeling, students were differentiated based on similarity of score changes. This study showed that the first-year program of the science-focused school significantly improved students' scientific core competency and science learning motivation. A group-based trajectory modeling found that about 40~60% of students saw the effects of the program. The students who chose the humanity track showed effects, while some students who chose the science-focused track did not show effects. A group-based trajectory modeling showed the methodological effects of identifying the change process of individual students. This study identified the positive effects of science-focused school policy statistically and is a meaningful example for analyzing the effectiveness of science-focused school programs.
