To develop computational thinking skills, university students are learning how to solve problems with algorithms, program commands and grammar, and program writing. Because non-computer majors have difficulty with computer programming-related content, they need a learning method to acquire coding knowledge from the process of understanding, interpreting, changing, and improving source codes by themselves. This study explored clone coding, refactoring coding, and coding methods using reconstruction tools, which are practical and effective learning methods for improving coding skills for students who are accustomed to coding. A coding learning process with the code reconstruction principle was designed to help non-computer majors use it to understand coding technology and develop their problem-solving ability and applied the coding technology learning method used in programmer education.

Aiming at the poor compression quality of traditional image compression coding (ICC) algorithm, a multi-description ICC algorithm based on depth learning is put forward in this study. In this study, first an image compression algorithm was designed based on multi-description coding theory. Image compression samples were collected, and the measurement matrix was calculated. Then, it processed the multi-description ICC sample set by using the convolutional self-coding neural system in depth learning. Compressing the wavelet coefficients after coding and synthesizing the multi-description image band sparse matrix obtained the multi-description ICC sequence. Averaging the multi-description image coding data in accordance with the effective single point's position could finally realize the compression coding of multi-description images. According to experimental results, the designed algorithm consumes less time for image compression, and exhibits better image compression quality and better image reconstruction effect.

When it comes to the value of modern education, teachers are required to perform the role of a helper to promote interaction between learners, the role of a manager to facilitate smooth learning, and the role of a guide who has expert knowledge in the learning contents. Therefore, this study investigated what kind of learner-centered teaching methods there are, which require teachers to perform the roles of helper, manager, and guide, and conducted a pedagogical research on coding education to explore class models for self-directed learning. Subsequently, a class model was proposed by applying the flipped learning and havruta learning to a coding class. In this study, the learner-centered education methods of flipped learning and havruta method were applied to constructing a coding class as a university general education course. The feature of this class is that it enables dynamic interaction between teachers and learners as well as active interaction between leaners in a classroom instruction. After applying the proposed method to the actual class and analyzing it, the students taught using suggested method were more positively assessed in learning interest than those taught using a traditional method. And that in academic achievement as well, suggested method was more effective.

본 연구는 대학의 교양수업인 코딩수업에 플립드 러닝을 적용한 사례 연구이다. 컴퓨터를 전공하지 않는 학생들이 배우는 교양 코딩 수업은 전문가 양성을 위한 코딩 교육과는 차별화된 교육방법이 필요하다. 본 연구에서는 교양 수업으로의 코딩교육을 위한 플립드 러닝 수업 모형을 제안하고 그 효과 및 가능성을 살펴보았다. 학습자는 언제 어디서나 원하는 시간, 장소에서 온라인 콘텐츠로 학습을 하고, 수업시간에는 학습된 내용에 근거한 실습교육에 집중하는 플립드 러닝을 통해 교수 학습의 효율을 극대화하는 방안을 모색하였다. 실제 수업에 적용 후 사전 사후 설문을 실시하여 플립드 러닝 방식의 수업을 진행한 학생들이 전통적인 방식으로 수업을 진행한 학생들보다 학습만족도에 대해 긍정적으로 평가하였고 학습 성취도에 대한 결과도 더 나은 효과가 있음을 확인하였다.

시큐어코딩은 악의적인 공격 혹은 예상치 못한 오류에 대한 강인함을 제공해줄 수 있는 안전한 코딩 기법으로 정적분석도구의 지원을 통해 취약한 패턴을 찾아내거나 오염 데이터의 유입 가능성을 발견한다. 시큐어코딩은 정적기법을 적극적으로 활용하는 만큼 룰셋에 의존적이라는 단점을 가지며, 정적분석 도구의 복잡성이 높아지는 만큼 정확한 진단이 어렵다는 문제점을 안고 있다. 본 논문은 시큐어코딩을 지원하는 목적으로 기계학습 기법 중 DNN과 CNN, RNN 신경망을 이용하여 개발보안가이드 상의 주요 보안약점에 해당하는 패턴을 학습시키고 분류하는 모델을 개발하며 학습 결과를 분석한다. 이를 통해 기계학습 기법이 정적분석과 더불어 보안약점 탐지에 도움을 줄 수 있을 것으로 기대한다.

When carrying out computer programming, the process of checking and correcting errors in the source code is essential work for the completion of the program. Non-computer majors who are learning programming for the first time receive feedback from instructors to correct errors that occur when writing the source code. However, in a learning environment where the time for the learner to practice alone is long, such as an online learning environment, the learner starts to feel many difficulties in solving program errors by himself/herself. Therefore, training on how to check and correct errors after writing the program source code is necessary. In this paper, various types of errors that can occur in a Python program were described, the errors were classified into simple errors and complex errors according to the characteristics of the errors, and the distributions of errors by Python grammar category were analyzed. In addition, a coding learning process to refer error lists was designed to present a coding learning method that enables learners to solve program errors by themselves.
