The purpose of this paper is to explore the educational direction and present improvements of the local college of engineering through the business feasibility and analysis of the universities that conducted financial support projects to improve engineering education. For this study, we analyzed a three-year of survey on the business satisfaction of the university that implemented aid for innovation in engineering education. A result of statistical analysis on the performance of the education programs and operations that performed by the participants in the project shows that the overall satisfaction rate of the support projects has increased from 73.8% to 83.4%, but the average rate of the related industries has relatively decreased. The research shows that the satisfaction level of creativity and problem-solving ability of new employees in task performance was low so that the overall satisfaction level of the business decreased. We are going to come up with improvement plan to develop creative problem solving skills through the design of program for engineering education innovation in the future.

The purpose of this study was to investigate the relationship between media richness, media usefulness, media experience and media decision in order to identify factors that determine the media of school library in solving performance evaluation tasks. For this purpose, 132 primary and middle school students were surveyed and their structural equation was set up by hypothesis setting, validity test, and causal model. As a result, it was confirmed that media experience of school library is a major factor in media decision. Also, media richness and media experience appeared to influence media decision through media usefulness. The analysis implies that school library is centered on teaching - learning process and evaluation, so information literacy education should be carried out in school curriculum and school library is required to provide students experience on media as the center of school education.

The aims of this study is figure out the characteristics of justification patterns and mathematical representation which are derived from 14 mathematically gifted middle school students in the process of solving the spatial tasks on Archimedean solid. This study shows that mathematically gifted students apply different types of justification such as empirical, or deductive justification and partial or whole justification. It would be necessary to pay attention to the value of informal justification, by comparing the response of student who understood the entire transformation process and provided a reasonable explanation considering all component factors although presenting informal justification and that of student who showed formalization process based on partial analysis. Visual representation plays an valuable role in finding out the Idea of solving the problem and grasping the entire structure of the problem. We found that gifted students tried to create elaborated symbols by consolidating mathematical concepts into symbolic re-presentations and modifying them while gradually developing symbolic representations. This study on justification patterns and mathematical representation of mathematically gifted students dealing with spatial geometry tasks provided an opportunity for understanding their the characteristics of spacial geometrical thinking and expending their thinking.

A Discrete continuation Method/homotopy approaches are studied for energy/fuel optimal low thrust Earth escape trajectory by solving a two point boundary value problem(TPBVP). Recently, maneuvers using low thrust propulsion system have been identified as emerging technologies. The low thruster is considered as the main actuator for orbit maneuvers. The cost function consists of a energy/fuel consumption function, and constraints are position and velocity vectors at the terminal escape point. Solving the minimum energy/fuel problem directly is not an easy task, so we adopt the homotopy analysis. Using a solution of the minimum energy, which is solved by discrete continuation method, we obtain the solution of the minimum fuel problem.

The purpose of this study was to develop an integrated program to improve the creative and emotional ability of lower grade students. This program aimed to cultivate creative thinking and creative personality for problem solving, and to learn how to interact positively with others by developing emotional expression and control. Creative thinking ability includes fluency, flexibility, originality, elaboration, imagination, and sensitivity. Creative personality includes curiosity, sensitivity, adventure, humor, independence, task commitment, and problem solving leadership. We selected 6 creative thinking skills such as mind-map and brainstorming. Emotional factors consist of self /other understanding, control of emotional effect, self-expression emotionally, and respect for others for cooperation. The integrated program consisted of 12 themes, and the class time was set to 40 minutes, which is the same as the elementary curriculum. The program was conducted by a teacher with 10 years' experience.

Due to increase in software-based new technologies, software developers are being required to creative problem solving. Especially, for a successful business change of software developers into a new industrial field, software analysis phase and design phase are important and it is an important task to strengthen these competences. In this study, two independent researches were conducted. First, a survey with 300 software developers was conducted and it was explored that uniform thinking of software developers caused by application of "standard software development methodology" made it difficult to approach creative problem solving. Based on this finding, the influences of 9 competences of computational thinking on software developers were analyzed after selecting 111 software developers with over 10 years of experience in the IT industry. As a result, it was revealed that abstraction was an important competence. The study finding demonstrates that software developers recognized design phase as the most important thing and abstraction of CT is the basics of other competences.

The purpose of the present research was to study the self-regulation of the child during mother child interaction. That is. this study focused on how mothers regulated children's problem solving efforts before children began to function as independent agents capable of self-regulation. The emphasis was on the "regulation-by-others" that preceded "self-regulation". The subjects of this study were 30 mother-child dyads. The dyads were divided into 3 groups of 10 dyads each on the basis of the child's age (2, 3, and 4 years of age). The instrument used for this study was the "truck puzzle" devised by Wertsch, McNamee, Mclane and Budwig (1980). The problem solving task in this study required the dyad to make a puzzle in accordance with the model puzzle. The interaction of 30 mother-child dyads was observed and analyzed flH verbal and non-verbal behavior used by the mother to regulate the child's behavior. One-way ANOVA, Scheffe post hoc comparision and Spearman's rank-difference correlation were used for the statistical analysis of the data. The results revealed that there were significant age trends in regulation-by-others and self regulation in joint cognitive activity; that is, there were developmental transitions from regulation by-others to self-regulation in connection with crucial strategic behavior (looking at the model). Significant differences were found in mothers' interventions after children's gaze at the model in joint cognitive activity; that is, the mean proportion of mothers' intervention for the 2-year-old group was the highest and that of the 4-year-old group was the lowest. There were no significant age-related differences in mothers' use of referential perspectives in joint cognitive activity. Children's regulation- by-others increased and children's self-regulation decreased in proportion to mothers' use of referential perspectives.

Three experiments were conducted to investigate whether different types (common vs. uncommon) of prior-examples entail different effects in creative problem solving, and whether types/levels (rich or lean. common or uncommon) of background knowledge interact with types of prior-examples. It was found that the example types and the types/levels of background knowledge do interact and have some differential effects on generating novel and useful ideas. In Experiment 1 and 2. uncommon examples had a positive effect - generating many novel and useful ideas. regardless of background knowledge types. while common examples had positive effects, only when the background knowledge was somewhat uncommon In Experiment 3 it was also found that types (irrelevant,. single common. single uncommon, or multiple common + uncommon) of background knowledge seemed to influence differently on the ease of finding solutions: when background knowledge is diverse or not directly related to the task problem, uncommon prior examples produced much greater number of novel ideas than it was with single common or sin91e uncommon background knowledge. Implications of the present study were discussed. in relation to mental sets and fixation.

The purpose of this study is to examine the effects of health related departments' self-efficacy on stress-coping strategies by setting up grade and sex as regulating variables and figure out their mediating effects. To attain the goal, a survey was conducted to 1,442 undergraduates attending S University, and the results went through analysis by using SPSS and AMOS. To sum up the study results, preference of difficult project exerted negative effects on avoidance-centeredness. Self confidence had negative effects on avoidance-centeredness. Self-regulating efficacy indicated positive effects on social support-orientation and problem solving-centeredness while avoidance-centeredness showed negative effects. Regarding effects among self-efficacy's subfactors, confidence, self-regulating efficacy, and preference for task difficulty, and stress-coping strategies' subfactors, social support-orientation, problem solving-centeredness, and avoidance-centeredness, there was difference found in the model by grade, but there was no difference found by sex.

Previous studies reported that gifted students' capacity on mathematics had high correlations with results of the performance assessment. However, there have been few studies that develop recommending tools through the assessment that can be used to identify mathematically gifted students or analyse their applications. Then it is difficult to use them to identify mathematically gifted students practically. Therefore, this study developed the tasks and evaluation tables for the tools. And one of them was applied for four students in Grade 1 of a middle school to simulate the assessment and characteristics assessment teachers showed were analysed. As the results, the extensive and specific information on the giftedness of the students was obtained through using the tool. The gifted capacity grasped from the order, speed, and attitudes of problem-solving was identified as observing the process of solving the task.
