Adaptive Behavior in Stroke Survivors: A Concept Analysis
Choi Hyunsuk,임안초,송영신 한국간호과학회 2022 Asian Nursing Research Vol.16 No.4
Purpose: This study aims to explore a clear and evidence-based definition of adaptive behavior in stroke survivors and establish the antecedents, attributes, consequences, and empirical referents of the concept. Methods: The concept analysis was performed using theWalker and Avant method as a framework. Data from 90 publications were collected using various databases (PubMed, EMBASE, CINAHL, RISS, and KISS) and applied in the analysis. Results: Adaptive behavior in stroke survivors was defined according to four attributes: realizing change, taking an optimistic view, restructuring daily activities to suit oneself, and carrying out one's own daily life. The conceptual structure of their adaptive behavior comprised stroke onset, functional changes, and emotional liability as antecedents and autonomy, family equilibrium, and quality of life as consequences. Conclusions: Clarifying the concept of adaptive behavior in stroke survivors provides an understanding of the underlying attributes of this concept. Furthermore, it will facilitate the development of scales to measure the concept and the application of a theory-based intervention program that can improve adaptive behavior.
Service quality of Rural Accommodations in South Korea
Hyunsuk Choi 전북대학교 산업경제연구소 2015 아태경상저널 Vol.7 No.1
The aim of this study is to examine the most important service quality factors for rural accommodations in rural tourism villages in South Korea by simultaneously utilizing Importance-Performance Analysis (IPA). Among the 18 items measuring the service quality of rural accommodations, 11 items fall in the first quadrant which indicates high performance and importance values. The seven remaining items were located in the third quadrant, meaning they were of less importance but also had a low performance. Management of rural accommodations in South Korea must make special efforts to maintain and improve service quality for the 11 high performance and importance value attributes. On the other hand, management might want to consider not focusing on and allocating resources to the 7 attributes located in the third quadrant.

<P><I>Pseudomonas aeruginosa</I> is a causative agent of chronic infections in immunocompromised patients. Disruption of quorum sensing circuits is an attractive strategy for treating diseases associated with <I>P. aeruginosa</I> infection. In this study, we designed and synthesized a series of gingerol analogs targeting LasR, a master regulator of quorum sensing networks in <I>P. aeruginosa</I>. Structure–activity relationship studies showed that a hydrogen-bonding interaction in the head section, stereochemistry and rotational rigidity in the middle section, and optimal alkyl chain length in the tail section are important factors for the enhancement of LasR-binding affinity and for the inhibition of biofilm formation. The most potent compound <B>41</B>, an analog of (<I>R</I>)-8-gingerol with restricted rotation, showed stronger LasR-binding affinity and inhibition of biofilm formation than the known LasR antagonist (<I>S</I>)-6-gingerol. This new LasR antagonist can be used as an early lead compound for the development of anti-biofilm agents to treat <I>P. aeruginosa</I> infections.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jmcmar/2017/jmcmar.2017.60.issue-23/acs.jmedchem.7b01426/production/images/medium/jm-2017-01426j_0015.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/jm7b01426'>ACS Electronic Supporting Info</A></P>

To determine the vertical dimension and centric relation during the construction of implant overdentures, the record base and wax rim may need to be adjusted. The conventional method has several drawbacks, as it requires repeated tightening and loosening of the impression coping. Here, we report a useful and novel method for interocclusal records using the healing abutments in implant overdentures. Our case demonstrates that this method is easier and simpler and prevents gingival collapse.
