Dynamic capabilities for smart manufacturing transformation by manufacturing enterprises
Lin Tzu-Chieh,Sheng Margaret L.,Jeng Wang Kung 기술경영경제학회 2020 ASIAN JOURNAL OF TECHNOLOGY INNOVATION Vol.28 No.3
The article compares patenting patterns in China with the United States, South Korea, Japan and Europe, using the case of graphene, 2011–2015. It aims to reveal unique features of patenting in China and identify patent descriptors, diverging from international tendencies and relevant for economic modelling. Hypotheses rely on variables such as: counts of inventors, applicants, technology classes, countries selected for international patenting and geographical origins of patent citations. The research uses quantitative techniques (descriptive statistics, ANOVA, Jaccard index and social network metrics). Using multiple analytical perspectives, the study demonstrates the specificity of Chinese patents and their limited comparability with documents from other patent offices. This has important implications for the development of economic models, which need to take into account the identified incommensurability in cross-country patent data and avoid direct comparisons of data from China and other patent systems owing to the unique features and functions of patents in China.

In this article, thermal nanoimprint lithography (thermal-NIL) has been utilized to transfer the microgroove pattern onto the plastic substrate. Without coating alignment polymer, the microgrooves on the flexible substrates can align liquid crystals (LCs) directly. The flexible LC cell is shown to maintain comparable electro-optical properties while bending. The plastic film and the alignment layer integrated into an alignment substrate could effectively prevent cracks of the additional polymer alignment layer during the bending process. This method is applicable to the roll-to-roll process to increase the production efficiency.

TV 쇼핑 채널에서 판매하는 보험상품의 구매의도에 관한 연구
( Chieh Wei Hung ),( Hyun Jee Kim ),( Hui Tzu Lin ) 한국유통경영학회(구 한국유통정보학회) 2013 유통정보학회지 Vol.16 No.2
본 연구에서는 인구통계학적 변수와 TV 쇼핑 구매경험, 단일 지출 최대 금액을 독립변수로 하여, 종속변수인 TV 쇼핑 채널에서 판매된 보험 상풍에 대한 소비자들의 구매 의도를 분석하였다. 인구통계학적 변수 중소비자들의 결혼상태와 소득 수준, 자녀의 수가 소비자들의 구매의도에 영향을 주는 의미 있는 변수로 분석되었다. 특히, 중산층이며 부양 자녀를 둔 소비자들은 이러한 보험 상품에 대하여 높은 구매의도를 보이고 있었다. 더불어 지금까지 TV 쇼핑 채널에서 보험 상품이나 주방기구를 구입한 경험이 있는 소비자일수록 TV 쇼핑 채널에서 판매되는 보험 상품을 재구입하고자 하는 의도를 강하게 가지고 있었다. 또한 TV 쇼핑에서 한 번에 160만 원 이상을 지출한 소비자일수록 TV 쇼핑 채널에서 판매되는 보험 상품을 구매하고자 하는 의도가 더 높았다. In this study, we investigated the determinants of consumers` purchase intention of insurance products sold On TV channel in Korea. Among the demographic variables, consumers` marital status, income level and the number of children are significant variables for consumers` purchase intention. Consumers of middle income class and having dependent children have significant intention to purchase the insurance products. Besides, consumers who have ever purchased insurance products or kitchen utensils on TV shopping channel before, have significantly high intention to buy the insurance products. The higher the amount spent on TV shopping at a single time, the higher intention of consumers to purchase insurance products sold on TV shopping channel.

Background: To compare risk of diabetic retinopathy (DR) between patients taking sodium-glucose cotransporter-2 inhibitors (SGLT2is) and those taking glucagon-like peptide-1 receptor agonists (GLP1-RAs) in routine care.Methods: This retrospective cohort study emulating a target trial included patient data from the multi-institutional Chang Gung Research Database in Taiwan. Totally, 33,021 patients with type 2 diabetes mellitus using SGLT2is and GLP1-RAs between 2016 and 2019 were identified. 3,249 patients were excluded due to missing demographics, age <40 years, prior use of any study drug, a diagnosis of retinal disorders, a history of receiving vitreoretinal procedure, no baseline glycosylated hemoglobin, or no follow-up data. Baseline characteristics were balanced using inverse probability of treatment weighting with propensity scores. DR diagnoses and vitreoretinal interventions served as the primary outcomes. Occurrence of proliferative DR and DR receiving vitreoretinal interventions were regarded as vision-threatening DR.Results: There were 21,491 SGLT2i and 1,887 GLP1-RA users included for the analysis. Patients receiving SGLT2is and GLP-1 RAs exhibited comparable rate of any DR (subdistribution hazard ratio [SHR], 0.90; 95% confidence interval [CI], 0.79 to 1.03), whereas the rate of proliferative DR (SHR, 0.53; 95% CI, 0.42 to 0.68) was significantly lower in the SGLT2i group. Also, SGLT2i users showed significantly reduced risk of composite surgical outcome (SHR, 0.58; 95% CI, 0.48 to 0.70).Conclusion: Compared to those taking GLP1-RAs, patients receiving SGLT2is had a lower risk of proliferative DR and vitreoretinal interventions, although the rate of any DR was comparable between the SGLT2i and GLP1-RA groups. Thus, SGLT2is may be associated with a lower risk of vision-threatening DR but not DR development.
