Today, as customer demands are diversified and convergent attempts are actively made between industrial areas, new perspectives and approaches to product development methodologies are required. Reflecting this trend of the times, this study designed a framework for case analysis using the PSS development methodology, which is drawing attention as a new method of product development. The research target is a South Korean general electronic component manufacturer that develops and produces key materials and components in the mobile, display, optics, semiconductors, automobiles, and IoT sectors. In recent years, the company developed and commercialized Dash-cam using optical technology, one of its core technology capabilities, and developed and commercialized ESL systems for retail stores using wireless communication and IoT sensor technology. As a result, Dasch-cam failed in business, and ESL can be evaluated as successful. The reason for Dash-cam's failure is due to insufficient consideration of the service system to be added to the product, and the reason for ESL's success is because the project was defined based on the PSS attributes of the product and the process and support organization was operated accordingly. This study is of academic significance in that it presents a development framework from a PSS perspective, and it is of practical significance in that it discovered success and failure factors of PSS development through case studies.

Globalization and technological development require organizations to adopt supply chain data analytics in their supply chain to enhance their performance and decision-making. This research aims to evaluate Tableau software's effectiveness on learning outcomes in the field of supply chain analytics. Visualization allows students to learn better supply chain management (SCM) strategies. Using the actual demand data during the recent Covid-19 pandemic, we attempt to teach the effect of data visualization techniques on students' analytical skills. To examine students' understanding, we have collected 66 students' surveys in Fall 2021 through undergraduate-level classes. The result indicates that employing the Tableau tool promotes the student's learning and comprehension of demand forecasting. Also, we compared exam scores from fall 2020 and fall 2021, a year apart, to evaluate students' learning outcomes. It shows that students understood demand trend analysis using Tableau. It is important that the concept of supply chain analytics and experiential software tools such as Excel and Tableau. This study examines whether Tableau software impacts students' demand forecasting learning. In sum, students better understand the relationship between data analysis regarding demand forecasting, that is, for supply chain analytics and supply chain management.

These days, as become active, we try to prove effect that awareness of meaning out on purchasing behavior and customer loyalty. For this purpose, we described prior literature and we examined various researches to provides understanding of relationships with Ethical consumption. To verify these hypotheses, data were collected through survey, and the data were tested by reliability, validity, correlation, structural equation modeling analysis. Ethical/Social Duty, Altruism, Ego-identity are impact on social cognitive consumption positively, but it`s not related with activist consumption. However, Ethical/Social Duty is positive impact on activist consumption as well as loyalty. Till now, study only focus on Ethical consumption refer to personal morality. However this study expands from individual, neighbor to social for subject of consumption, and personal belief of political/social refer to meaning out impacts on theoretical and business perspective.
