The purpose of this study is to analyze the effects of a comparative process so that students majoring in urban planning and design can develop the ability to present non-physical alternatives along with the ability to present alternatives to a physical environment to solve urban problems. A total of 30 students majoring in urban planning and urban design were analyzed for their satisfaction with their majors, intention to find a job related to their majors, and academic achievement. This was done after conducting a comparative course of living-lab projects utilizing idle space in a region in connection with a major education course for about a year. For the analysis, the four-group design used by Solomon was used to find the differences between students who participated in the class and those who did not. The analysis showed that the students who participated in the comparative course of the living-lab project were highly satisfied with their major and their intention to find a job related to their major. The results of this study suggest that the process of cultivating the ability to work with local residents and merchants to present physical and non-physical alternatives to solve local problems by utilizing the means of living lab projects has a positive effect on the students' attachment to their majors and their self-esteem.

The purpose of this study is to investigate the current conditions of the domestic and foreign curricula in the field of chemical engineering and to draw implications. The results of the study are as follows. Most of the domestic research universities (including non-certified universities) have curricula organized within the scope of the ABEEK certification, which is the minimum standard guide for chemical engineering curricula. However, we are concerned that chemical engineering education in some domestic universities may lack in education quality and program relevance. Graduates from these universities may not have equivalent qualifications as international graduates. It is considered that most of the 12 domestic universities organize their subjects according to the certificate of accreditation standard and to the traditional subjects of chemistry in the 'Department of Chemical Engineering' or 'Department of Chemical and Biological Engineering Chemical and Biological Engineering'. However, due to the increase in the number of overlapping subjects with other majors because of the movement towards academic diversity, the integrity of the chemical engineering curricula is at risk. In addition, after surveying the major and research areas of the department professors, it has been found that there is a shortage of professors who have majored in chemical engineering. Therefore, there is a concern that students may lack understanding of the core principles of chemical engineering. The results of the analysis of the curricula of overseas research universities (including non-certified universities) are as follows. Although the chemical engineering industry in developed countries like the United States and Europe is advancing and changing very quickly, the chemical engineering education in these countries is highly focused on traditional subjects and other related subjects in order to cultivate traditionally trained chemical engineers. The Department of Chemical Engineering at overseas universities still maintains the academic integrity of the chemical engineering field. This is a significant suggestion for our country. On the other hand, domestic universities are changing the name of their chemical engineering major, or even if the name is maintained, they are fusing their curriculum with other majors such as material engineering. Therefore, it is very necessary at this point to start a discussion regarding the integrity of the department of chemical engineering in Korea. We hope that the departments of chemical engineering in domestic universities maintain the integrity of traditional chemical engineering while operating the curriculum within the scope of the standards of the engineering education certification system.

In this paper, we propose a layered pattern authentication scheme resistant to social engineering attacks. Existing android pattern lock scheme has some weak points for social engineering attacks. Thus, the proposed scheme improves the existing pattern lock scheme. In our scheme, pattern is recorded by touch screen, however, it is different with existing schemes because of the layered pattern. During the pattern registration process, users register their own pattern with many layers. Thus, registered pattern is 3D shape. When the smudge attack is occurring, the attacker can see the shape of user pattern through the smudge on smartphone screen. However, it is described on 2D surface, so acquired pattern is not fully determine to users original 3D shape. Therefore, our scheme is resistant to social engineering attack, especially smudge attack.

This paper deals with how to design and develop white-box based e-learning contents which are equipped with conceptual understanding and step-by-step computational procedures for studying vector calculus for science-engineering majors who might need supplementary mathematics learning. Noting that rewriting rules are often used in school mathematics for students' problem solving, the theoretical aspects of rewriting rules are reviewed for developing supplementary e-learning contents for them. The software design of step-by-step problem solving requires careful arrangement of rewriting rules and pattern matching techniques for white-box procedures using a computer algebra system such as Mathematica. Several modules for step-by-step problem solving as well as producing dynamic display of e-learning contents was coded by Mathematica in order to find the length of a curve in vector calculus after implementing several rules for differentiation and integration. The developed contents are equipped with diagnostic modules and immediate feedback for supplementary learning in terms of a tutorial. At the end, this paper indicates the strengths and features of the developed contents for college students who need to increase math learning capabilities, and suggests future research directions.

In this paper, as a liberal arts course for non-majors, we proposed a supervised learning artificial neural network parameter optimization method and a basic education method for activation function to design a basic artificial neural network subject curriculum. For this, a method of finding a parameter optimization solution in a spreadsheet without programming was applied. Through this training method, you can focus on the basic principles of artificial neural network operation and implementation. And, it is possible to increase the interest and educational effect of non-majors through the visualized data of the spreadsheet. The proposed contents consisted of artificial neurons with sigmoid and ReLU activation functions, supervised learning data generation, supervised learning artificial neural network configuration and parameter optimization, supervised learning artificial neural network implementation and performance analysis using spreadsheets, and education satisfaction analysis. In this paper, considering the optimization of negative parameters for the sigmoid neural network and the ReLU neuron artificial neural network, we propose a training method for the four performance analysis results on the parameter optimization of the artificial neural network, and conduct a training satisfaction analysis.

In this paper, to design a basic data science practice curriculum as a liberal arts subject for non-majors, we proposed an educational method using an Excel(spreadsheet) data analysis tool. Tools for data collection, data processing, and data analysis include Excel, R, Python, and Structured Query Language (SQL). When it comes to practicing data science, R, Python and SQL need to understand programming languages and data structures together. On the other hand, the Excel tool is a data analysis tool familiar to the general public, and it does not have the burden of learning a programming language. And if you practice basic data science practice with Excel, you have the advantage of being able to concentrate on acquiring data science content. In this paper, a basic data science practice curriculum for one semester and weekly Excel practice contents were proposed. And, to demonstrate the substance of the educational content, examples of Linear Regression Analysis were presented using Excel data analysis tools.

In the SW education of non-majors who encounter liberal arts education experience difficulties in the SW development environment and understanding they encounter for the first time, relevance to their major, and convergence thinking ability. In order to compensate for the difficulties of non-major learners in liberal arts education, a relatively easily accessible software was used to utilize a demonstration-oriented model that can be applied to beginners in SW education. In order to understand the logical flow of applications and problem solving used in real life, we proposed a convergence SW teaching method that combines repeated implementation through demonstration by the instructor and imitation of the learner, and learning indicators to increase the learning satisfaction and achievement of the learner. In the experiment applying the teaching and learning method proposed in this paper, meaningful results were shown when evaluating the learning effect, academic achievement, learning satisfaction, and teaching and learning method aspects of SW education.

Most of the courses that teach the Python programming language are liberal arts courses that all students in general universities must complete. Through this, non-major students who have learned the basic programming process based on computational thinking are strengthening their convergence capabilities to apply SW in various major fields. In the previous research results, various evaluation methods for understanding the concept of computational thinking and writing code were suggested. However, there are no examples of evaluation problems, so it is difficult to apply them in actual course operation. Accordingly, in this paper, a Python basic programming curriculum that can be applied as a liberal arts subject for non-majors is proposed according to the ADDIE model. In addition, the case of evaluation problems for each Python element according to the proposed detailed curriculum was divided into 1st and 2nd phases and suggested. Finally, the validity of the proposed evaluation problem was analyzed based on the evaluation scores of non-major students calculated in the course to which this evaluation problem case was applied. It was confirmed that the proposed evaluation problem case was applied as a real-time online non-face-to-face evaluation method to effectively evaluate the programming competency of non-major students.
