The demand on applying the performance-based logistics (PBL) in the operational phase of the weapon systems development is increasing these days. Therefore, the enhancement of the PBL concept and process needs to be done. This is the objective of the paper. As a method of approach, a modeling method is adopted to cover the whole life cycle of the weapon systems development from the concept development to the operation. The modeling results for the PBL process yield an useful suggestion for improvement. Also, by analyzing the interrelationship model between the PBL process and the integrated logistics support (ILS) procedure, it is possible to take advantage of the PBL concept in the ILS elements development, which is usually carried out from the beginning of the development phase, a lot earlier than the operational phase. Note that the PBL concept has been restrictively applied in only the supply support among many ILS elements up until now. However, the results obtained in the paper can make it also possible to consider the availability, reliability, logistics support, cost and so on from the early phase of the weapon systems development.

In many existing studies, the analyses on the application and effect of the project-based learning model (PBL), a student-centered teaching and learning strategy, have been emphasized and carried out in various majors and courses. This case study analyzes the effects of applying a project-based learning model to the engineering accounting course for engineering students in 2021 in the context of the COVID-19 pandemic, compared with the offline course in 2019 and the simple online course in 2020. Project team consisting of 2-3 students carried out online collaborative learning activities for solving open-ended problems through the 5-step PBL procedure including presenting the final result. Except for this online PBL application in 2021, textbooks, lecture contents, assignments, and tests were implemented the same for each semester for three years. Through lecture evaluation and survey by students, the online PBL application semester showed higher effects in inducing student-centered learning, lecture satisfaction, and student competency improvement compared to the non-applying semesters, further, it was evaluated that the online PBL application to the course and evaluation method were more appropriate than other semesters. It is expected that the online PBL method and operation procedure applied in this study can be utilized as a best practice for the design and operation of various online courses for student-centered collaborative learning activities and educational effects.

The purpose of this research was examining the effects of problem-based learning strategies(PBL) on problem solving skill conducted in Korea, using meta-analysis technique. This meta-analysis reviewed the results of 41 studies published between 1998 and 2017 in Korea. The overall weighted mean effect size value was .753 with .064 standard error which was calculated by random effects model. PBL strategies have been found to be more effective in mathematics course (d=.922), art course (d=.916), practical art course (d=.827), E-PBL (d=.791) and middle school level (d=.972). As PBL exhibit a substantial effect on students' problem solving skill, it is recommended that teachers should learn how to implement these strategies in their lesson. PBL is expected to contribute to the improvement of teaching methods as the learning environment changes during the 4th Industrial Revolution.

Purpose: This study aimed at (a) developing an instructional model of creative thinking education on the problem-based learning method (C-PBL) in undergraduate nursing curriculum at one University, and (b) examining its effect on nursing students' level of creativity and outcomes from problem-based learning. Methods: The C-PBL model was implemented on 43 juniors of the experimental group with a 30 hour-nursing class during one semester. The control group, with 54 seniors, received 4 hours of problem based learning training in an adult nursing class. Pre-and post-tests were done with the Torrance Tests of Creative Thinking for creative thinking ability, the Integrated Creativity Instrument for creative motivation and attitudes, the Problem Solving Competency questionnaire, and the Self-Directed Learning Instrument. Results: The C-PBL model was developed using a caring situation scenario to solve nursing problems with 3 training steps of 'encountering a patient in a caring situation', 'exploring nursing knowledge', and 'designing creative caring beyond given knowledge'. Between the experimental group and the control group, there were significant differences in creativity (p<.010), problem-solving ability (p<.010), and self-directed ability (p<.010). Conclusion: This C-PBL method could contribute in increasing creative competency as well as problem-solving ability for nursing students.
