This paper deals with the free vibrations of horizontally curved beams with the general boundary condition, which consists of translational and rotational springs. The equations of general boundary condition of such beams are derived, while the ordinary differential equations governing free vibrations are adopted from the literature. The parabola as the curved beam's curvilinear shape is considered in numerical examples. For calculating the natural frequencies, the governing equations are solved by numerical methods. The Runge-Kutta and Determinant Search Methods are used for integrating the differential equations and for calculating the natural frequencies, respectively. for validation purpose, the numerical results obtained herein are compared to those obtained from the SAP 2000. With regard to numerical results, the relationships between frequency parameters and various beam parameters are presented in the forms of Table and figures.

Student independent project activity is beneficial for enhancing many kinds of abilities, e.g., team working, collaboration, communication, presentation, creativity, leadership, and so on. More than ten project teams actively perform every year in the Center for Innovation and Creativity Development of The University of Tokushima. The project management workshop was planned in order to make project activity successful. In this workshop, the team members studied the importance of holding a common objective among them and of making a clear plan for achieving the activity. They practiced brainstorming method and KJ method and experienced a PDCA cycle. The team activity will be fruitful on the basis of the project management method.

Educational data analysis is attracting increasing attention with the rise of the big data industry. The amounts and types of learning data available are increasing steadily, and the information technology required to analyze these data continues to develop. The early identification of potential dropout students is very important; education is important in terms of social movement and social achievement. Here, we analyze educational data and generate predictive models for student dropout using logistic regression, a decision tree, a naïve Bayes method, and a multilayer perceptron. The multilayer perceptron model using independent variables selected via the variance analysis showed better performance than the other models. In addition, we experimentally found that not only grades but also extracurricular activities were important in terms of preventing student dropout.

It is an after-school material for elementary school student based on STEAM education which has a theme of water pollution as a global issue. First of all, we take a look at various ways of measuring water pollution and among them, we include experiment for student to know about the water pollution by using indicator organisms. Next, we examine how some elements in our daily life affect on water and provide class with systematically technological and engineering solution. With this text book, we let the student recognize environmental problem and seek for the solution about it. Therefore, it helps student to connect with stream of thought.

Blended learning is a teaching method utilizing all the advantages in 'on and off-line' learning circumstances in order to enhance the learning effect and efficiency, more than the simple use of online factors in the classroom education. In this paper, we present the realization and simulation of algorithm for the realtime evaluation of low-grade and high-grade subjects in order to implement smart e-learning system, considering a lecture intelligibility. In order to grasp the levels of student's intelligibility, we simulated a function that automatically summarizes the study contents of class given by a lecturer. Especially, in administrator mode of smart e-learning system, we suggested and simulated a system in order to help the lecturer to easily manage the student's grades, and we have provided software to tell the student's intelligibility of lecture, analyzed the rate of incorrect answers, automatic judgment of lecture intelligibility and judge the weakest subject.

The purpose of this study is to investigate the effect on the university student' attitude toward environmental problem with PBL. The controlled group consisted of 80 students who was applied PBL and experimental group was applied a traditional teaching method was consisted with 80 students. The results is as follows ; First, there was a statistically meaningful differences in attitudes toward environment between two group(F=52.789, p<0.1). It shows that PBL is very effective in attitude toward environment. Second, there was a more meaningful increasing effect of student' consciousness of environmental problems before and after environmental education on the controlled group which was applied PBL than experimental group which was applied a traditional teaching method. Finally, in the literacy education of university student' related with environment problems recommend that PBL is more effective than that of traditional teaching method.

본 연구는 공학계열 대학생을 대상으로 학습민첩성과 취업준비행동의 관계에서 학습몰입과 교수-학생 간 상호작용의 조절된 조절효과를 확인하는 것을 목적으로 한다. 이를 위해 2년제 P대학 2학년 재학생 206명으로부터 수집한 데이터를 바탕으로 Process v3.5.3 for SPSS를 활용하여 연구 모델의 조건부 효과(직접효과 및 조절된 조절효과) 분석을 실시하였다. 연구결과 첫째, 공학계열 대학생의 학습민첩성은 취업준비행동에 유의한 정적 영향을 미치는 것으로 나타났다. 둘째, 학습민첩성과 취업준비행동의 관계에서 학습몰입은 유의한 부적 조절효과가 존재하는 것으로 나타났다. 셋째, 학습민첩성과 취업준비행동 관계에서 학습몰입의 조절효과는 교수-학생 간 상호작용 빈도에 의해 조절되고, 그 영향은 통계적으로 유의하고 정적인 것으로 나타났다. 연구결과를 바탕으로 학문적·실무적 논의와 시사점을 제시하였다.

As the dropout rate of university students is gradually increasing, the studies on exploring the status, characteristics, reasons, and countermeasures of dropout of university students are currently grabbing high attention. This paper analyzes the relationship between the admission types and dropout of university students, mainly focused on engineering students. The analysis shows that the dropout rate of engineering students admitted through the scheduled-time admission procedures is quite higher than that of students admitted through non-scheduled-time admission procedures, the dropout rate of engineering students admitted from the vocational high schools is higher than that of students from the academic high schools, and the dropout rate of engineering students admitted from the liberal art high school tracks is higher than that of students from the natural science high school tracks. From the results, we could find out that student-support programs need to be carefully provided for the engineering university students according to their admission types and underlying backgrounds.
