There are several claimed benefits for the impact of design patterns (DPs) on software quality. However, the association between design patterns and fault-proneness has been a controversial issue. In this work, we evaluate the fault-proneness of design patterns at four levels: the design level, category level, pattern level, and role level. We used five subject systems in our empirical study. As a result, we found that, at the design level, the classes that participate in the design patterns are less fault-prone than the non-participant classes. At the category level, we found that the classes that participate in the behavioral and structural categories are less fault-prone than the non-participant classes. In addition, we found that the classes that participate in the structural design patterns are less fault-prone than the classes that participate in the other categories. At the pattern level, we found that only five patterns show significant associations with fault-proneness: builder, factory method, adapter, composite, and decorator. All of these patterns except for builder show that the classes that participate in each one of them are less fault-prone than the non-participant classes in that pattern. The classes that participate in the builder design pattern were more fault-prone than the non-participant classes and the classes that participate in several patterns: the adapter, the composite, and the decorator design patterns. At the role level, the most significant differences were between the classes that participate in some roles and the non-participant classes. Only three pairs of design pattern roles show significant differences. These roles are concrete-product vs. concrete-creator, adapter vs. adaptee, and adapter vs. client. The results recommend the use of design patterns because they are less fault-prone in general except for the builder design pattern, which should be applied with care and addressed with more test cases.

본 연구는 조경설계 수업 전반에 대한 학생들의 인식을 조사하고, 설계수업 개선을 위한 방향을 도출하고자하였다. 본 연구는 점차로 대학교육이 절대적인 지식을 전달하는 실증주의적 배경으로부터 학생들 스스로가 지식을 구축해가는 구성주의적 교육방법으로 진화해야 한다는 가정을 둔다. 학생들이 설계수업을 어떻게 경험하고, 느끼고, 이해하고, 평가하고 있는지를 이해하는 것은 이러한 구성주의 철학과 관점을 바탕으로 설계수업을 개선하기 위한 첫 번째 단계이다. 본 연구에서는 설계 스튜디오 교육에 대한 이론적 연구로 교육철학의 변화, 스튜디오 수업의 기원과 변화, 건축분야의 설계 교육의 변화, 그리고 조경교육에 있어서 설계교육에 대한 논의를 고찰하였다. 이를 바탕으로 네 개 대학의 학부생을 대상으로 실시한 설문조사의 내용을 분석하였다. 그 결과, 설계수업은 학생들이 조경설계가로서의 진로를 결정하는데 긍정적 혹은 부정적 영향을 행사하는 것으로 나타났다. 절반 정도의 학생들은 설계수업에 대해 불만을 표시하였으며, 상당한 심적 부담감을 느끼는 것으로 나타났다. 특히 설계과정의 초기단계와 개념을 구체화하는 단계에서 가장 많은 스트레스를 받는 것으로 분석되었고, 진로에 대한 유보적인 집단이 설계수업에 대한 심적 부담감이 가장 큰 것으로 나타났다. 학생들은 스스로의 설계능력에 대해 부정적으로 평가하고 있었으며, 성적이 학생들의 설계능력을 잘 반영해준다고 강하게 믿지 않는 것으로 나타나, 보다 투명한 평가체계에 대한 고민이 이어져야함을 시사한다.

The qualitative effect of class is influenced by the instructor's class design and operation method, but it comes from motivating students to actively participate in class and utilizing potential qualities that lead to student-centered learning. Students' activities and the quality development of class participation can be utilized in presentation-based classes. This could be confirmed through the presentation classes in English language curriculum applied to English major students in Korea. In other words, with presentations conducted in language-theoretic classes such as phonetics/phonology, and syntax, it turned out that immersion in learning, concentration on class, and motivation for learning can be improved, developing systematic self-directed learning ability and cooperative mutual communication ability. Instructors need to lead the direction and design of the classes, but the actual educational effect depends on how students accept the academic tasks, how well they understand the learning contents, and how well they can systematically transmit them to others. In this respect, this study aims to investigate that learner-centered presentation classes contribute to making learners develop their competencies in class design, data utilization, imparting knowledge, and communication, which would bring about the improvement of learning quality and educational effects.

Seismic performance analysis is one of the fundamental steps in the design of new or retrofitting buildings. In the seismic performance analysis, the adapted spectral acceleration curve for a given site mainly governs the seismic behavior of buildings. Since every soil site (class) has a different impact on the spectral accelerations of input motions, different spectral acceleration curves have to be involved for every soil class that the building is located on top of. Modern seismic design codes (e.g., Eurocode 8, EC8, or Turkish Building Earthquake Code, TBEC) provide design response spectra for all the soil classes to be used in the building design or retrofitting. This research aims to evaluate the EC8 and TBEC based design response spectra using the spectra of real earthquake input motions that occurred (and were recorded at only soil classes A, B and C, no recording is available at soil class D) in a specific area in Turkey. It also conducts response spectrum analyses of 5, 10 and 13 floor reinforced concrete building models under EC8, TBEC and actual spectral response curves. The results indicate that the EC8 and especially TBEC given design response spectra cannot be able to represent the mean actual spectral acceleration curves at soil classes A, B and C. This is particularly observed at periods higher than 0.3 s, 0.42 s and 0.55 s for the TBEC design response spectra, 0.54 s, 0.65 s and 0.84 s for the EC8 design response spectra at soil classes A, B and C, respectively. This is also reflected to the shear forces of three building models, as actual spectral acceleration curves lead to the highest shear forces, followed by the shear forces obtained from EC8 and, then, the TBEC design response spectra.

The purpose of this study is to provide implications for designing and implementing non-face-to-face online classes at the College of Engineering in the post-corona era by analyzing the instructors' evaluations and experiences of non-face-to-face online classes operated in the COVID-19 pandemic. According to the overall evaluation results of non-face-to-face online classes from instructors at the College of Engineering, 'instructional design' was the highest among the five areas including instructional design, learning management, learning support, learning evaluation, and instructional outcomes. In addition, the effectiveness of non-face-to-face online experimental or practical classes was found to be relatively low. The results of this study imply that the instructors need to consider several instructional strategies such as active interaction with learners, clear explanation, and the use of technology in non-face-to-face online engineering classes.

This paper studies the effect of flipping the classroom in undergraduate physics classes using English as the medium of instruction (EMI). Data on student use of learning strategies, course satisfaction level and perceptions of the flipped classes were collected through a survey including close-ended and open-ended questions. The sample size was 71 students in flipped classes, with 60 students in non-flipped classes used as a control group (total N=131). It was found that students in the flipped classes showed greater intrinsic goal orientation (p<.05), control of learning beliefs (p<.05), and use of critical thinking (p<.01) than those in the non-flipped classes. While the survey highlighted problems of student engagement with the pre-class activities, students who had previous experience with online classes committed more time to pre-class, suggesting that engagement may improve with exposure to blended learning. It is concluded that the flipped classroom helps students develop their identities as self-directed learners, but that more support is necessary for weaker students in the EMI context. Implications are drawn for the content design of flipped EMI classrooms.

This study developed and taught VR content to be used in clothing design and composition practice, which are practical subjects for home education students at the College of Education, and examined the learning effects on students who participated in VR experiences. First, after experiencing classes using VR content, students' perceptions of classes were examined considering participation, class level, expectations, and satisfaction through a survey. As a result of examining the experience of learning sewing machines in classes using VR content and changes in perception of classes, it was found that the class level, class expectations, and satisfaction were affected. As a result of comparative analysis of VR experiences and the perception of VR classes prior to experiencing VR content related to sewing machines developed for practical subjects, VR experiences affected class participation, class level, expectations, but satisfaction was not affected. The advantages of the VR class that students mentioned in the subjective evaluation included interest in the class, the degree of participation, the VR experience, and the use of VR. As for the disadvantages, difficulties in using the device, dizziness, frustration when using the device, and limitations of the program were mentioned.
