The purpose of this study is to develop an educational model based on the capacity analysis of college students. In order to measure the learning ability of female science and engineering students, we used various tools to derive core competencies. The competency element of human resources implementation, the element of learning achievement area in the undergraduate education actual condition survey, and the analysis of the learning achievement elements of the engineering certification program were analyzed and the development of teaching method was searched to find ways to increase the competence of female students. In addition, we developed a model that can apply the development of pedagogy in the curriculum to the liberal arts, majors, and comparative courses, and presented the internship in field experience area, the improvement of on the spot learning, and teaching method and guidance to enhance the female students' competence. Also, as a case study of the proposed teaching method, new curriculum of 'Understanding of Big Data' which is the basis of the fourth industrial revolution technology in the second semester of 2016 was developed and applied to the education model. The results of this study are very positive, and we can expect the effectiveness of the new education model to enhance the learning ability and capacity of female students.

This study examines the possibility of a learning environment design model for enhancing creativity in engineering education. Recent studies about the online support system and the blended learning pertinent to creativity have provided us with some new perspectives on how to teach the creativity in engineering college. A learning environment design model was developed to enhance the creativity of the engineering students. A model was developed by following three steps: finding out the general principles for enhancing creativity in engineering education by reviewing the relevant literature; extracting the theoretical components for the model by categorizing the general principles; and finally, developing specific guidelines based on those theoretical components. Seven general design principles and three theoretical components could be identified, and a set of specific design guidelines was suggested. The result of this study is significant in terms of guiding the future development projects for creativity education.

The purpose of this study was to examine the current states of role model and effects on the expertise development in engineers (i.e., undergraduate students and experts in the field of engineering). Based on the previous studies, role model was categorized into two domain, general role model and value sharing role model. A total of 257 participants (162 undergraduate students, 95 experts) answered survey questions about their role model (the number of their role model, the frequency of meeting with them, and the number of sharing value with them), major confidence, knowledge acquisition, and research performance. The results showed that engineers had 1 or 2 general role models and that the contents of role model were different between the two groups. The value-sharing role model significantly predicted major confidence and research performance in undergraduate students whereas the number of general role model was closely associated with major satisfaction in experts. These results suggest that it is important for engineering major students to have general role model and value-sharing role model in order to enhance expertise development. Establishing infrastructure for having and meeting with role models can facilitate the development of personal expertise in engineers.

The main purposes of this study was to develop evaluation model, which provides program educational objectives(PEO) evaluation research with guidances on how to evaluate the program educational objectives and procedures in order to enhance the quality of engineering education. Educational objective evaluation is reciprocal processes that depend on and affect one another. Thus, the evaluation component deals with how to identify members' strengths, weakness, and needs, how to assess and improve the effectiveness of curriculum programs, and how to provide data that assist in decision making. After literature reviews about the case studies on the program educational objectives evaluation, this study, to understand the meaning of education evaluation and the engineering accreditation, and then, examined the evaluation model for program educational objectives. This study suggested evaluation components of program educational objectives. In particular, the distinctions between diagnostic, formative, and summative evaluation are discussed. The result of this study is significant in terms of guiding the future evaluation model development for program educational objectives.

In this study, we applied the long short-term memory (LSTM) model to classify the cryptocurrency price time series. We collected historic cryptocurrency price time series data and preprocessed them in order to make them clean for use as train and target data. After such preprocessing, the price time series data were systematically encoded into the three-dimensional price tensor representing the past price changes of cryptocurrencies. We also presented our LSTM model structure as well as how to use such price tensor as input data of the LSTM model. In particular, a grid search-based k-fold cross-validation technique was applied to find the most suitable LSTM model parameters. Lastly, through the comparison of the f1-score values, our study showed that the LSTM model outperforms the gradient boosting model, a general machine learning model known to have relatively good prediction performance, for the time series classification of the cryptocurrency price trend. With the LSTM model, we got a performance improvement of about 7% compared to using the GB model.

The purpose of this study is to suggest the general education contents for undergraduate students at engineering related departments through need analysis in order to develop creative and integral talents. For this study, the need analysis was conducted by using focus group interviews, Borich's educational need equation and the Locus for Focus Model, and highly ranked priorities on both methods proposed as the highest priorities. As a result, 'drawing up a letter of self-introduction and a portfolio', 'understanding fields', 'understanding careers related to the major', 'presentation skills', 'knowledge for certificated exams', 'method to deduct creative ideas' were high on the list of top five priorities. The selected items by Locus for Focus Model show that undergraduate students at engineering related departments need general education contents associated with career development and communication by priority.

Protein adsorption on the polyurethane surface was modelled by a modified random sequential adsorption(RSA) process. In this model, polyurethane surface was modelled as a mixed domain of hydrophobic and hydrophilic parts which was implemented by a 2 dimensional $150{\times}150$ lattice in the computer. Protein adsorption was simulated using a small box which represents a particle of the protein, and polyurethane lattice by considering their hydrophobic interaction. In order to validate the model, we perfonned fibrinogen adsorption on polyurethane surface. Isotherms of the adsorbed protein were calculated and compared to the experimental data. The protein adsorption on the polyurethane surface could be well described using this computer model.

The ODA(Official Development Assistance) of Korea is growing considerably, and the ODA projects in the technical and vocational education have the good performance to the recipient countries, because they have the direct and quick benefits. But there are no economic model of performance measurement for the ODA in the technical and vocational education. The purpose of this study is to develop the economic model of measuring the performance of the ODA in the technical and vocational education. This study use the ROI model using financial information and the BSC model using non-financial information, and link each model closely. The ROI model using financial information is more relevant, because the benefits of the technical and vocational education are distinct and quick to the recipient groups.
