This paper suggests a collaborative business process between the companies that each has a restricted physical branch in its own area and wants to extend globally sales and delivery service. The companies integrate their business processes for sales and delivery using a shared product taxonomy table. We also suggest a similar product finding algorithm to make the product taxonomy table that defines product relationships to exchange them between the companies. The main idea of the proposed algorithm is using a multi-attribute decision making (MADM) to find the utility values of products in a same product class of the companies. Using the values we determine what products are similar. It helps the product manager to register the similar products into a same product sub-category. The companies then allow consumer to shop and purchase the products at their own residence site and deliver them or similar products to another sites.

The purpose of this study was to examine how computer conferencing might facilitate collaborative learning for students to engage in meaningful discussion. The participants in this study consisted of the instructor and the students in a graduate level course. Different sources of evidence were used to triangulate the data: in-depth interviews, content analysis of transcripts of discussion, and other archival data including course syllabus, presentation materials, and lecture notes. Participants perceived web-based learning as collaborative process, providing opportunities to share the idea, respect and evaluate different perspectives, and co-construct new insights. Analysis of the data revealed several challenges related collaboration in a web-based learning environment: absence of a sense of community, technical problems, adaptability to different types of learner, and managing the discussion. The data also indicated that a variety of strategies were used to facilitate learning: building a sense of community, technical support, developing instructional methodologies, class size, and design of the content.

Purpose: This study was conducted to design and implement a fundamental nursing practice based on flipped learning and to examine the effects. Methods: Participants were 57 students who were taking the fundamental nursing practice course at D university in N city. The study included processes of instructional design, action/effects and reflection. Data were analyzed using paired t-test with the SPSS/WIN 23.0. Results: In the instructional design stage, the class consisted of 3 parts: outside class (pre-learning), inside class (assessment, collaborative practice, peer review, reflection), after-class (self-directed practice, feedback). In the action/effects stage, the flipped learning was applied for 15 weeks according to the instructional design and then the effects of flipped learning were evaluated. Students showed a significant improvement in self-directed learning ability (t=-3.56, p=.001) and critical thinking disposition after the class (t=-3.72, p<.001). Finally, in the reflection stage, the researchers examined whether the four pillars of flipped learning occurred. Conclusion: Findings indicate that flipped learning applied in fundamental nursing practice is effective in improving self-directed learning ability and critical thinking disposition. The action research method was a useful way to foster professor's educational competency as well as to verify effects of a new nursing education method.

This study introduces an engineering design class which is experimental in a sense that it is planned and implemented with three key concepts such as learner-centered education, living lab and community based learning. With the class run in being connected with one regional community in Seoul, it focuses on its educational effects acquired through the living lab-based approach. And this research investigates the student's experiences of when, what and how they learn in a learner-centered class. It shows that, rather than taking professor's one dimensional lectures in classroom, the students learn actively when they face with the problem in the field. Students have come to carry out engineering design from the perspective of stakeholders, not from the supplier or producer's perspective in the process of meeting with the problem in reality. Team based collaborative activities are crucial in the entire design process. More importantly, students' design products have been transformed into more useful and meaningful ones as stakeholders of the local community have participated into the students' works. However, we need to recognize that there are some important issues that need to be solved institutionally and systematically in order for such educations to spread. This study suggests several educational arrangements for those issues.

본 연구는 제품의 구매자와 수령자가 상이한 글로벌 협업 전자상거래를 구현하기 위한 비즈니스 모형 및 절차를 제안한다. 글로벌 협업 전자상거래를 수행하고자 하는 기업은 해당 기업의 소재 지역에만 지점을 보유하고 있으며 판매 및 물류 프로세스 협업을 통해 글로벌 판매를 수행하고자 한다. 해당 기업들은 교환 가능한 제품분류표를 공유함으로 인해 글로벌 협업 전자상거래를 수행할 수 있다. 이를 위해서는 기업들이 보유하고 있는 판매 제품과 교환판매가 가능한 제휴 기업의 제품을 찾아내기 위한 알고리즘이 필요하다. 본 연구에서는 제휴 기업간 교환 판매를 위해 교환 가능한 제품들을 찾아내기 위한 유사상품발견 알고리즘을 제안한다. 이 알고리즘은 제휴 기업들의 제품분류표에서 동일한 제품 군에 속해있는 제품들의 사양 값에 따라 효용 값을 계산하는 다기준 의사결정기법에 근거한다. 제안된 알고리즘에 근거한 글로벌 협업 전자상거래 모형을 활용하게 되면 기업들은 물리적 지점의 확장 없이 글로벌 판매를 수행할 수 있으며 고객은 자신의 거주 지역에서 구매한 제품을 다른 지역으로 저렴하게 배달시킬 수 있게 될 것이다.

The study investigates the effects of online instructional facilitator's qualities on student performance of online class activities. The study explores the roles of instructional facilitators who may influence student performance of online class activities and their academic achievement. The study employs a set of aggregated data from 1,362 subjects and 10 facilitators who participated in multiple online classes. The results of independent samples t-test reveal that the student performance in online classes has no association with facilitators' educational background or academic degree, as well as demographic characteristics, student evaluation records and instructional achievement. The results of multiple regression analysis show that the facilitator engagement has a positive relation to the enhancement of student interaction, reading discussion messages, and the quality of discussion messages in online discussions. The results of correlation analysis show that the facilitator engagement has a positive impact on both increasing the number of reading discussion messages and enhancing the quality of discussion messages. The facilitator engagement increases the quantity of reading discussion postings and enhances the quality of discussion messages, which would be a substantial contribution to student performance by facilitators. The findings suggest that student performance and academic achievement in online classes are not independent of facilitator engagement.

Purpose: The study aims to analyze differences in the satisfaction level of dental technology students regarding in-person and online classes. It also aims to provide fundamental resources for the improvement of major subject class methods that will improve students' self-directed learning abilities, thereby affecting their class satisfaction. Methods: In this study, a self-administered questionnaire was conducted from November 8 to November 30, 2021, for 256 dental technology students. The collected data were analyzed using the IBM SPSS Statistics ver. 21.0 statistical program. Frequency and percentage, mean, standard deviation, t-test, ANOVA, post-hoc test, correlation analysis, and linear regression analysis were performed to analyze the data. Results: In the self-directed learning abilities, the attitude of the learners was shown to have the highest positive (+) correlation in both in-person and online classes, with a statistically significant effect (p<0.001) on class satisfaction in major subject classes. Moreover, the explanatory power of the model was 52.2% and 39.7%, respectively. Conclusion: We concluded from the study that there is a need for professors to improve teaching methods to increase learners' self-directed learning competence, through problem-based learning, discussion learning, team-based collaborative learning, and mentor-mentee learning, thereby enabling learners to lead classes themselves.
