In this study, we tried to understand the effect and satisfaction of education perception on beauty education and its effect on Intention to Retrain, and to understand the correlation between each intention among students participating in after-school beauty education programs of beauty specialized high schools. According to the survey, those surveyed chose after-school beauty programs because they were likely to have the right interest and aptitude, and confirmed positive responses that after-school beauty education reduced the burden of private education. In addition, the correlation between the recognition and effectiveness of beauty education, satisfaction level and retraining level of those surveyed was confirmed. Based on this data in the future, it is believed that effective operation of the after-school beauty education program will be needed to enhance the quality and satisfaction of beauty education.

The purpose of this study was to analyze the contents of the sound environment among the various environmental factors that directly or indirectly affect the quality of education through the remodeling of the small hall of the College of Humanities at W University. Before remodeling into a lecture room, the small hall of the College of Humanities at W University, which is the subject of this study, was designed to create an indoor sound environment suitable for a lecture room by recognizing differences in acoustic performance between the performance halls that require adequate sound quality and the lecture rooms where the clarity of voice is important. Therefore, this study aimed to present examples of improved acoustic performance in lecture rooms by remodeling through the stages of measuring acoustic performance before remodeling, presentation of a change in finishing materials through sound simulation, and measurement of sound performance after remodeling. It is expected that this process can be used as an example of securing indoor acoustic performance suitable for educational space, such as lecture rooms, by changing the finishing materials.

As foodservice industry has been developing, more people are interested in healthy life and want to learn cooking. This study validated the moderating effect of education program on cooking institutes. Also the present study revealed cause and effect relationship among the education environment, the satisfaction and reregistration intentions by conducting a survey for trainees in cooking institutes located in Busan and Gyeongnam area. For the purposes of the study, conjunction and organic cause-and-effect relationship of entire model was validated by using an exploratory factor analysis, confirmatory factor analysis and structural equation modeling with 313 trainees who have used cooking institutes. A nested model and basic model were established to analyze the moderating effect of education program. The adjustment role of education program was validated with ${\chi}^2$ difference considering the degree of freedom between two models. As results of the analysis, the education service was statistically significant in all factors except the effect on education satisfaction. The education program has moderating effect on the relationship between the level of instructor and satisfaction degree, and between satisfaction degree and the reregistration intentions. Therefore, this study suggests that managers of cooking institutes should recruit instructors with excellent capability in order to operate the education program very well.

Most existing mobile distance learning systems are asynchronous ones that allow students to download lecture video and presentation material. However, there are a few synchronous real-time mobile distance learning systems that support slide, annotation, feedback from student, and lecture video and audio at the same time. These live mobile distance learning systems have an advantage of supporting real-time interaction between students and a lecturer thereby making students understand the lecture better. But, they also have a disadvantage in the sense that they don't allow students to experience the past lecture. This problem can be solved by recording and replaying lecture session. So far, there are few mobile distance learning systems that support session recording and replay. This paper presents a synchronous mobile distance learning system that supports video and audio, slide with annotation, and real-time feedback from students, as well as session recording and replay, which is not supported by the existing mobile distance learning systems. The evaluation of the system among students shows that 61.3% of them were satisfied while 3.2% weren't.

Recently, the form of education has changed from one-way to two-way and mutual exchange rather than the existing one-way order form, and accordingly, it is necessary to consider creating a suitable learning environment for each type of education. The basic form of education consists of the delivery of knowledge, that is, the delivery of knowledge by teachers to education consumers through voice delivery, so the sound environment is considered an essential factor in creating a pleasant learning environment. The indoor sound environment is very closely related to the mental stress of the inmate, so the quality level of education will also change greatly depending on whether or not the appropriate sound environment is created. However, the importance of the sound environment in educational facilities such as classrooms has not been highlighted due to the lack of research and related laws on the sound environment. Therefore, in this study, auditory tests were conducted using the auralization based on the physical acoustic performance data presented in the preceding study. Through this, we wanted to verify the validity of this research by analyzing the subjective acoustic performance satisfaction of the occupants due to the improvement of the physical acoustic performance. Based on these research results, it is estimated that the improvement of the sound environment of educational facilities through remodeling in the future will be possible to verify whether the sound environment suitable for educational facilities is created only after the analysis stage on the improvement of subjective sound performance as well as physical sound performance.

The experimental and the numerical study was performed on the comparison of thermal comfort(TC) and indoor air quality(IAQ) in the lecture room for cooling loads when the operating conditions are changed. PMV value and $CO_2$ concentration of the lecture room were measured and compared with the numerical results. The numerical results showed a good agreement with the experimental one and then the numerical tool was used to analyze thermal comfort and IAQ for a couple of operating conditions. As a result it was found that the increment of the discharge angle of system air-conditioner makes TC uniformity worse, but rarely affects IAQ. Also TC and IAQ were hardly affected by the variation of the discharge airflow. Finally it turned out that TC is merely affected by the increment of the ventilation airflow, but the average $CO_2$ concentration can be satisfied with Japanese IAQ standards of classrooms when the ventilation airflow is more than $800m^3/h$ in this study.

The purpose of this study is to find out the factors of the students' achievement on the computer training courses which are based on computer practice. In order to improve the academic achievement of the students, it is necessary to analyze the factors affecting academic achievement and apply the results of the analysis to education. In particular, it is necessary to study for finding out factors of the academic achievement in practical computer training courses, because these courses are different from other courses focusing on the theory. In this study, in order to find out the factors, the logistic regression analysis and the decision tree analysis which is the field of data mining were peformed. For the experimental data, the test results of the MOS certification of the S university in seoul were used. Through logistic regression analysis it is found that the factors of the professors, class size, lecture time, group(lecture period) are important in order. Through decision tree analysis of data mining, it is found that there are some additional factors ; entrance year, whether the course is retaken, and the classroom environment. and these various factors effect the academic achievement compositively as identified through the model tree. The tree model was presented as a result of the analysis, and the importance of the factors is expressed numerically from multiple tree models by using the proposed mathematical formula.

e-Portfolio in e-Learning environment is defined as the results which either teachers or learners systematically manage global contents related to their teaching and learning, respectively. When the e-Portfolio is applied to their work including teaching and learning, it is very useful for both teachers and learners to prepare their teaching plan, and to get the opportunity of their reflection by checking out their learning output, respectively. To generate e-Portfolios, there are two ways; one for collecting it directly from teachers and learners and another for collecting it automatically as a result of learning activities through e-learning system. In this paper, for efficient management of e-Portfolio, the data is layered, classified, restructured, and provided for users' purposes and various situations. Users can construct their own e-Portfolios by adding their own logic with their purposes in different situations.
