VFA(Vinylformamide)는 독성이 강한 Acrylamide를 대체할 수 있는 새로운 물질로 대두되고 있으며 VFA를 이용하여 다양한 형태의 PVAm(Polyvinylamine)을 합성하여 제지공정에 다양한 용도로 적용이 가능하다. 현재 제지산업의 가장 큰 목표는 기존 종이물성을 유지하면서 filler(탄산칼슘)의 첨가량을 늘려 원가절감을 실현하는 것으로 이러한 과정에서 종이 강도 저하, 인쇄품질 저하, 공정오염 등의 많은 문제가 발생되며 이러한 문제를 해결할 수 있는 약품으로 PVAm이 주목받고 있다.

Purpose: In this research, it is aimed to examine the valu echain that 3on3 basketball players recognize b y using means-end chain theory. Method: In order to investigate the value chain of basketball cultur, econtent analysis was conducted using the APT Laddering Method, which draws keywords related to featrues, benefits, and value of basketball cu-l ture. There were five keywords for the features of 3on3 basketball culture. These were: ‘easy accessibility’, ‘fast pace’, ‘unconstrained team forming’, ‘simplification in rules’ ,and ‘importance of personal skills’. There wer e five keywords for the benefits of 3on3 basketball culture. These were: ‘physical fitness’, ‘promoting friendship’, ‘stress reduction’, ‘efficient use of time’, and ‘increasing confidence’. There were 4 key words for the value of 3on3 basketball culture. These were: ‘physical fitness’, ‘expanding social network’, ‘healthy leisure activity’, and ‘self-improvement’. After coding features, benefits, and the value of 3on3 basketball culture based on the results of content analysis, implication matrix analysis was carried out. Results: The results of this study are as follows. The link between e「aftures-benefits-value」 of 3on3 basketball culture was identified and the value chain was obtained from this. To begin with, fast pace (n=245), easy accessibility (n=208), importance of personal skills (n=200), unconstrained team forming (n=196), and simplification in rules (n=159) emerged in order as the features of 3on3 basketball cultuer. Stress reduction (n=269), physical fitness (n=229), promoting friendship (n=223), and increasing confidence (n=130), and efficient use of time (n=124) emerged in order as the benefits from 3on3 basketball culture. Two core ladders of 3on3 basketball culture were found on the basis of the value chain between 「features-benefits-value」. The first ladder was 「fast pace → physical fitness → promotion of health」, and the second one was 「unconstrained team forming → promoting friendship → expanding social network」. Conclusion: In all the studies reviewed here, it can be noticed that as 3on3 basketball has emerged as a new sport. The physical fitness and health of players have been improved at a phenomenal rate. Furthermore, since there is hardly limitation on the way of organizing teams, its ipossible to promote mutual friendship between wider ranges of people and provide opportunities to expand social networks of players.
