The purpose of this study was to development a model of problem solving instruction for improving practical skill-competence in technical high school. For the study, various literature researches were reviewed intensively about problem solving process, laboratory instruction's approaches and learning principals. The problem solving instruction process was composed with identifying problems, generating alternative solutions, investigation and research, choosing a solution, acting on a plan, modeling of problem solving, testing and evaluating, redesigning and improving. The skills schema combines a four domain of skilled activity, that is, cognitive skills, psychomotor skills, reactive skills and interactive skills. The problem solving instruction was composed with five major learning systems-emotional, social, cognitive, physical, and reflective-that can be used extensively as generic lesson plashing. The teacher serves as a coach or guide for student learning. As a facilitator, the teacher challenges, questions, and stimulates the students in their thinking, problem solving and self-directed study. In this process, students represent problem with think aloud, assume responsibility for their learning and move from teacher-centered to student-centered education.

Conceptual Modeling is the process of abstracting a model from a real or proposed system. It is probably the most important aspect of a simulation study. Relate works show that the elementary developers devoted little time to understanding how the systems actually worked, namely they didn't build appropriate conceptual model. Thus, the result of simulation is inconsistent because it depends on developer's competence. Although many researchers suggested various techniques enabling developer to build conceptual model, there were several limitations. In this study, to overcome the limitations of existing techniques, we proposed COMBINE-DES (COnceptual Model BuildINg framEwork using ontology for Discrete Event Simulation). The COM-BINE-DES supports expediting the conceptual modeling with Solution ontology generated by Domain ontology and Simulation ontology. Moreover, it provides consistent simulation result regardless of repeated modeling.

Purpose - Universities are fostering the development of closer relationships with students due to the increase in competition among universities. Universities are placing greater emphasis on relationship quality as a source of competitive advantage. Thus relationship marketing has become an important strategic theme in higher education. The purpose of this study is to investigate the effects of faculty trustworthiness on relationship building process in the context of relationship marketing. For this study, faculty trustworthiness is divided into competence, benevolence, and integrity. And relationship development variables are composed of satisfaction, commitment, positive WOM, and negative WOM. Research design, data, and methodology - To empirically evaluate the proposed research model, this study was carried out using the survey with undergraduate students who were taking business courses. The 270 questionnaires were asked, and a total of 245 respondents provided complete and usable data. The sample consisted of 143 males(58.4%) and 102 females(41.6%). The variables of proposed model were measured on a 5-point Likert scale. The structural equation modeling analysis was used for the hypothesis test. Results - The overall fit of the model was acceptable(χ²=579.7(df=264, P=0.00), GFI=0.935, NFI=0.949, CFI=0.956, RMR=0.040). The results supported 6 hypotheses except for

and

. First, competence and benevolence were positively related to satisfaction, while integrity was not significant. A key result of the analysis was that benevolence has the strongest effect on satisfaction. Second, satisfaction had a positive impact on commitment and positive WOM but didn't significantly affect negative WOM. Third, commitment significantly enhanced positive WOM and reduced negative WOM. Conclusions - This study emphasizes the role of faculty trustworthiness based on a long-term relationship. And the findings suggest that the dimensions of faculty trustworthiness have differing effects on satisfaction. In particular, benevolence is found to be the most important factor. This study provides university managers with the following managerial implications. In order to increase the satisfaction of the students, university managers should focus on the faculty's competence and benevolence. Also, it is important that university managers take a relationship approach to maximize WOM effect.

Purpose: The purpose of this study was to construct and test a structural equation model of self-management of liver transplant recipients based on self-determination theory. Methods: Participants were 275 outpatients who received liver transplantation. A structured self-report questionnaire was used to assess health care providers' autonomy support, transplant-related characteristics, illness consequence perception, autonomy, competence, family relatedness, depression and self-management. Collected data were analyzed using SPSS/WIN 24.0 and AMOS 24.0 program. Results: The modified model showed a good fitness with the data: GFI=.96, RMSEA=.06, CFI=.96, NFI=.93, TLI=.93, PGFI=.43, PNFI=.49. The health care providers' autonomy support, competence, family relatedness and depression were factors with a direct influence on the self-management of liver transplant recipients. The health care providers' autonomy support and illness consequence perception had an indirect influence through competence, family relatedness and depression. However, the transplant-related characteristics and autonomy did not have a significant effect on self-management. This model explained 59.4% of the variance in self-management. Conclusion: The result suggests that continuous education must be done to promote the competence of liver transplant recipients and to encourage the patient to positively perceive their current health condition with a view that enhances one's self-management. Additionally, the liver transplant recipients should be screened for depression, which would affect self-management. Most of all, health care providers, who have the most influence on self-management, should improve therapeutic communication and try to form a therapeutic relationship with the liver transplant recipients.

Technology-based start-ups have great economic ripple effect such as economic growth and job creation. Therefore, a strategic approach is required in order for such start-ups to continuously grow. However, many technology-based start-ups do not survive the Death-Valley and are being eliminated from the market. This is an empirical study on influencing variables that have impact on their performance. This study presents growth intention and influencing variables that have impact on performance (financial performance, technological performance) based on previous research on technology-based start-up. Also, this study examines the relationship between entrepreneurial competence, team commitment and growth intention, and finds the effect of controlling business-network. Structural equation modeling was performed in order to test the research hypothesis. Survey was conducted on the firms that have been certified by Youth Startup Academy of Small and Medium Business Corporation. A total of 306 samples were collected from the survey. An empirical test was conducted on the research hypothesis using SPSS 21.0 and Amos 22.0. The result of hypothesis test shows that growth intention has positive influence on both financial and technological performance, and entrepreneurial competence (technological competence, strategic management competence, creative competence and team commitment) has positive influence on growth intention. Also, the research proved that business-network has regulation effect between human resource trait and growth intention. The result of our study will provide practical insight to future start-ups for continuous growth and successful running of their firm.

Based on social capital theory, this study investigated the influence of the start-up founder's social competence on the start-up's access to funding sources and performance through the mediating role of the type of social network. This study aimed to examine two types of social networks empirically (i.e., personal networks and business networks) as social capital in analyzing the effect of the founder's social competence and social capital on the method of accessing funding sources. A self-report questionnaire was administered to 252 South Korean start-up founders whose businesses are based in South Korea. Path analysis and mediation effect analysis were performed by structural equation modeling(SEM) using STATA 16.1. This study examined the full mediating effect of the founder's social competence on his/her personal and business networks, respectively, and how the effect leads to different methods to approach funding sources. This is the first study in South Korea to analyze empirically how social competence has contrasting effects on personal and business networks as well as how each type of network varies in its influence on the method founders use to attract investment. This study is also significant in that it proposed a new methodology by utilizing the position generator as the measure of personal and business networks to analyze social networks in detail. The analyses of 252 survey data collected over a period of six months will be a valuable resource that may provide researchers, founders, investors, and other stakeholders in the start-up ecosystem with meaningful implications.

There has been a gradually increasing focus on adopting mathematical modeling techniques into school curricula and classrooms as a method to promote students' mathematical problem solving abilities. However, this approach is not commonly realized in today's classrooms due to the difficulty in developing appropriate mathematical modeling problems. This research focuses on developing reformulation strategies for those problems with regard to mathematical modeling. As the result of analyzing existing textbooks across three grade levels, the majority of problems related to the real-world focused on the Operating and Interpreting stage of the mathematical modeling process, while no real-world problem dealt with the Identifying variables stage. These results imply that the textbook problems cannot provide students with any chance to decide which variables are relevant and most important to know in the problem situation. Following from these results, reformulation strategies and reformulated problem examples were developed that would include the Identifying variables stage. These reformulated problem examples were then applied to a 7th grade classroom as a case study. From this case study, it is shown that: (1) the reformulated problems that included authentic events and questions would encourage students to better engage in understanding the situation and solving the problem, (2) the reformulated problems that included the Identifying variables stage would better foster the students' understanding of the situation and their ability to solve the problem, and (3) the reformulated problems that included the mathematical modeling process could be applied to lessons where new mathematical concepts are introduced, and the cooperative learning environment is required. This research can contribute to school classroom's incorporation of the mathematical modeling process with specific reformulating strategies and examples.

The purposes of this study were to provide evidence concerning the effects of Emotional Leadership and examine the impacts of Emotional Leadership on employee-related variables which were 'job satisfaction', 'organizational commitment', 'organizational performance', 'turnover intention'. A survey was conducted from August 23 to November 3, 2005 to collect data from kitchen staff(N=611). Statistical analyses were completed using SPSS Win(12.0) for descriptive analysis, reliability analysis, factor analysis, t-test, correlation analysis, cluster analysis and AMOS(5.0) for structural equation modeling. Kitchen staffs gave high point to their leader in the Emotional Leadership competence 'Optimism: seeing the upside in events' and 'Adaptability: flexibility in handing change' and gave lower point in the Emotional Leadership competence 'Inspirational leadership: guiding and motivating with compelling vision'. Employees' job satisfaction on 'coworker' were relatively high. However, the extents of satisfaction on 'payroll', 'promotion', 'work environment' were relatively low. The organizational commitment score was higher at 'loyalty' factor than 'commitment' factor. the test of hypothesis using structural equation modeling found that Emotional Leadership produced positive effects on job attitude and job performance. In conclusion, this study has identified that the Emotional Leadership effects on their organizational performance and attitudes toward their job.
