Background: 6-year College of Pharmacy curriculum had started in Korea, and the students in college of pharmacy are supposed to have student practice in the hospital pharmacy, community pharmacy, pharmaceutical company and administration to experience the role of pharmacists in advance. However, despite Korean Association of Pharmacy Education provided its own teaching plan, most Pharmacy Schools and the hospital pharmacy have difficulty in performing the desirable student practice program because they seldom experienced it. So, we reported the student practice program in the hospital pharmacy conducted by Yonsei University College of Pharmacy prior to the other numerous universities and the evaluation of survey on the student pharmacy practice program. Method: Severance Hospital, Gangnam Severance Hospital and National Health Insurance Service Ilsan Hospital took part in the student pharmacy practice program of Yonsei University. Students took 8-week pharmacy practice in Severance Hospital or Gangnam Severance Hospital plus 4-week pharmacy practice in National Health Insurance Service Ilsan Hospital. Also, students had once-a-week presentation class at school. A survey was conducted to evaluate the student practice program. Results: The presentation class was considerably helpful to share their own experiences at different practice sites in different hospitals, but there were some disadvantages that students could not experience the specific pharmacy practice site on the day of once-a-week presentation at school and so on. The results of the survey on the student practice program reported that students were satisfied with the overall practice program and presentation class at school. Also, they answered that the student practice program in the hospital pharmacy was significantly helpful for planning of the future career. Conclusion: Through the performance of the student practice program in Yonsei University, the adjustment of the student practice program in the hospital is planned to provide better experience of practice to the students and the results will be helpful for the student practice in the hospital of the other colleges of pharmacy.

This program of total 10 class was theoretical and experimental class and the students presented after collecting the synthetic data about climate-change and roleplayed what they debated to firm their country's opinion about Kyoto Protocol. Finally, students as policymaker made mock Kyoto Protocol by discussion. Impression papers and images about climate-changes was made by students in last class. In discussion of making up mock Kyoto Protocol, developed and developing nations had an argument about carbon dioxide emissions because of their economic benefits. In the course of allocating mutual $CO_2$ reduction, they needed yield and negotiation among nations. Although they mainly took passive position about $CO_2$ reduction, atmosphere that all the country make greater effort for the future global environment was formed. Like this, students had more concepts over climate change by making mock Kyoto Protocol.

Purpose : The purpose of this study is to explore the effectiveness of online blended learning(asynchronous online learning class 1+synchronous online learning class 2) method and discuss the applicability of online blended learning. In this study, we will analyze the differences in class satisfaction and academic achievement between asynchronous online learning and online blended learning classes, and discuss the strengths, weaknesses, and satisfactions of online blended learning. Methods : The subjects of this study were 39 of the occupational therapy students who took the 'child development' course. Asynchronous online learning class was applied for 1-6 weeks and online blended learning was applied for 9~14 weeks. The online blended learning class consisted of 1 hours synchronous online learning and 2 hours asynchronous online learning. For the asynchronous online learning, the screen recording program of OBS Studio was used, and for the synchronous online learning, the Zoom program was used. The results of course evaluation and academic achievement of students according to the type of lecture were compared, and a survey was conducted on the satisfaction of online blended learning. Results : The results of this study are as follows. First, satisfaction(A class: t=-4.19, p=.001, B class: t=-7.94, p=.00) with online blended learning classes was significantly higher than asynchronous online learning. Second, when applying online blended learning class, academic achievement(t=-10.58, p=.00) was significantly higher. Third, the online blended learning class showed the highest satisfaction in improving the interest in the subject, and it was found to be helpful in online class management, professor-student interaction, and class content understanding. Conclusion : We have found that online blended learning can compensate for the shortcomings of online lectures and increase the quality of the lectures and the satisfaction of students. The application of online blended learning should be supplemented according to the characteristics of each class, and I hope that blended online teaching methods can be developed based on new ideas in the future.

A pre-processing program based on the OOP(object-oriented programming) concept has been developed. The program consists of the input of a 2D or 3D flow problem to a CFD program by means of an user-friendly interface and the subsequent transformation of this input into a form suitable for the solver(PowerCFD) using unstructured cell-centered method. User-friendly GUI(graphic user interface) has been built on the base of MFC(Microsoft Foundation Class). The program is organized as modules by classes based on VTK(Visualization ToolKit)-library, and these classes are made to function through inheritance and cooperation which is an important and valuable concept of object-oriented programming. The major functions of this program are introduced and demonstrated, which include mesh generation, boundary settings, solver settings, generation of grid connectivity and geometric data etc.
