Polymer materials are used in a wide variety of fields such as automobiles, aerospace, energy, IT, and as well as simple household products. Despite high interest in the technological convergence of polymer materials for the sustaining progress, there have been only limited analyzes on the topic. This research attempted to analyze the types of convergence and the level of technology in the polymer materials field. For this purpose, we collected patent information from the PCT database and implemented a co-classification analysis. The research shows that Japan and Korea have more section-level convergence whilst US and Europe focus on field-level convergence. In terms of the quality measured by patent activity, patent competitiveness, and patent effect, Korean convergence technologies seem to be inferior to those of other countries.

With the increase of single households and more women entering society, changes to lifestyle, a demand for convenience, and the recent trend for homemade meals, the market for HMR(Home Meal Replacements) is rapidly growing. This study reviewed the repurchase intentions of consumers for RTP(Ready-to-Prepare) HMR products, namely meal kits, and the moderating effect. The study found that i) ease of use increases with higher self-efficacy; ii) ease of use decreases with higher personal innovativeness, but usefulness and repurchase intentions increased; iii) repurchase intentions increase with higher social influence; iv) trust decreases with higher convenience, but repurchase intentions increased; v) trust and repurchase intentions increase with higher economic efficiency; and vi) price sensitivity has a moderating effect between trust and repurchase intentions. The outcomes of this study will not only provide a theoretical basis for a more detailed study of HMR, but is anticipated to be used as fundamental data for suggesting a direction for marketing strategies for product development and sales.

Purpose: The purpose of this study was to investigate the effects of a modified constraint induced movement therapy (mCIMT) using proprioceptive neuromuscular facilitation (PNF) on the upper extremity function and activities of daily living (ADLs) in patients with subacute stroke. Methods: Fourteen participants with subacute stroke were randomly assigned to a group using both mCIMT and PNF or a group using mCIMT alone. Each group underwent twenty sessions (1 h/d, 5 d/wk) for 4 weeks. Patients were assessed with the action research arm test (ARAT), the Fugl-Meyer assessment for the upper extremities (FMA-UE), the Modified Barthel Index (MBI), and motor activity logs (MALs; amount of use [AOU] and quality of movement [QOM]). Results: Both the experimental group and the control group showed significant intragroup improvement in the ARAT, FMA-UE, MBI, and MAL-AOU (p<0.05). The group using both mCIMT and PNF exhibited greater improvement in the ARAT, FMA-UE, MBI, and MAL-AOU than did the group using mCIMT alone. Statistical analyses showed significant differences in the ARAT (p=0.01), FMA-UE (p=0.01), MBI (p=0.00), and MAL-AOU (p=0.01) between the groups. Conclusion: This study applied mCIMT combined with PNF for subacute stroke patients, and the results showed significant improvements in the patients' upper extremity function and ADLs. Therefore, mCIMT using PNF may be more effective than mCIMT alone in improving upper limb function and ADLs in patients with subacute stroke.

Objective: This study aimed to investigate the moderated-moderated mediating effects of children's media content selection and parental restrictive media mediation on the relationship between children's screen media time and executive function difficulties. Methods: A total of 693 parents of children aged 5~6 years participated in this study and were asked to answer all survey questions. The data were analyzed by descriptive statistics and correlation analysis using SPSS 27.0. Model 11 of PROCESS macro 4.3 was used to examine the moderated-moderated mediation model. Children's gender, age, childcare enrollment status, and household income were included in the analyses as covariates. Results: The moderated-moderated mediating effects of children's media content selection and parental restrictive media mediation were found to be significant. Specifically, bedtime mediated the relationship between screen media time and executive function difficulties only when parents did not appropriately implement restrictive mediation and children freely selected media content. Conclusion/Implications: It is recommended that parents understand the importance of implementing restrictive media mediation and selecting appropriate media contents for their child to prevent executive function difficulties in early childhood. Also, child education or day-care centers should offer education program about appropriate media use to reach more parents.
