Let M be a von Neumann algebra and .alpha., .betha. be *-automorphisms of M satisfying the operator equation .alpha.+.alpha.$^{-1}$ =.betha.+.betha.$^{-1}$ This operator equation has been extensively studied and many important decomposition theorems have been obtained by several authors (for instance see [4], [5], [2], [1]). Originally, this operator equation arose in the paper of Van Daele on the new approach of the Tomita-Takesaki theory in the case of modular operators ([7]). In the case of one-parameter automorphism groups, this equation has produced a bounded and completely positive map which can play a role similar to the infinitesimal generator (for details see [6] and [1]). A recent and one of the most important applications of this equation has been in developing an anglogue of the Tomita-Takesaki theory for Jordan algebras by Haagerup [3]. One general result of this theory is the following.

A novel finite element model based on the incremental endochronic theory with the effect of temperature was developed in this study to explore the deformed behaviors of a flexible pavement material. Three mesh systems and two loading steps were used in the calculation process for a specimen of three-dimensional circular cylinder. Computational results in the case of an uni-axial compression test for temperatures at $20^{\circ}C$ and at $40^{\circ}C$ were compared with available experimental measurements to verify the ability of developing numerical scheme. The isotropic response and the deviatoric response due to the thermal effect were presented from deformations in different profiles and displacement plots for the entire specimen. The characteristics of changing asphalt concrete material under a specified loading condition might be seen clearly from the numerical results, and might provide an useful information in the field of road engineering.

Purpose: This study discusses the phenomenon of the uncertain sustainability of SMEs in developing countries. SMEs face various challenges in the dynamics of a competitive environment, which threaten their growth and sustainability. This study aims to address a research gap between company's internal resources, in the form of absorptive capacity, and its business performance. By using product quality as a mediator, which has never been studied before, this research presents a novelty to answer the existing research gap using the Resource Based Theory (RBT) perspective. Research design, data and methodology: Using quantitative method, data are collected from 164 respondents, who are owners or managers of furniture manufacturing SMEs in Gerbangkertosusila Area, East Java, Indonesia. The data are analyzed using Partial Least Square (PLS) - Structural Equation Modeling (SEM). Results: The findings show that absorptive capacity has a direct and significant effect on business performance and indirectly through product quality. Conclusion: Furniture manufacturing SMEs are advised to focus on developing absorptive capacity reflected in good product quality, in order to improve their business performance. This is especially important to survive the crisis caused by the Covid-19 pandemic. Thus, the results of this study contribute to the development of RBT, and there are several suggestions for further research.

Practice evidenced by reliable knowledge is essential for professionals and practical studies. Because nursing is a human science and practical science, theory and knowledge development is an indispensable task to improve nursing. Nursing is a very special paradigm not exactly correlated to Western medicine and Oriental medicine. However, nursing was influenced by on Western medicine at the beginning, and most nursing theories were established western philosophies. Caring is the essence of nursing. To provide qualitative care which satisfies clients, it is required to respect cultures of the clients. Western and Eastern approaches of thinking are coexisting in Korea no, so the needs for developing a nursing model, East-West Nursing, which blends two approaches are increasing. In this paper, concepts of the East-West Nursing, differences between Oriental and Western medicines, and comparison of nursing metaparadigm in prospects from and Western Philosophies were briefly covered to define the East-West Nursing. Strategies and directions to develop the East-West Nursing were also discussed.

Social entrepreneurship is increasingly gaining interest in developing countries for the great benefits of society. In Vietnam, the concept of social entrepreneurship is still quite new. Entrepreneurial intention is regarded as a useful and practial approach for understanding actual entrepreneurial behavior. The purpose of this paper is to develop an integrated model based on planned behavior to examine the direct and indirect effect of perceived access to finance on social entrepreneurial intention. The confirm factor analysis to study the latent constructs underlying determinants of planned behavioral theory, perceived access to finance and social entrepreneurial intention. Then, it applies the technique of structural equation modeling to explore relationships among latent constructs. There is no direct relationship between perceived access to finance and social entrepreneurial intention. Perceived access to finance only indirectly increases entrepreneurial intention through attitude towards behavior and perceived behavioral. This study focuses on the perceptual factor of financial access that affects entrepreneurial intentions. The study does not cover other in-depth issues of social entrepreneurship such as decision making, leadership, personality traits, social capital, and human capital. To establish an environment with a strong social entrepreneurial intention, a focus on developing perceived access to finance is an extremely important factor. This study also suggests that attitude towards behavior and perceived behavioral have a strong impact to social entrepreneurship.

Background and purpose: We investigated existing nonpharmacological programs for people with dementia (PWD) to explore critical factors related to the effectiveness of these types of programs. Methods: We conducted a qualitative systematic literature review to identify nonpharmacological intervention programs developed for PWD and reviewed 36 randomized controlled trials. Among several outcomes reported in each study, we focused on the most common outcomes including quality of life (QoL), neuropsychiatric symptoms, depression, agitation, and cognition for further review. Results: Several factors were identified that might affect the outcomes of nonpharmacological interventions for PWD including study design, characteristics of the intervention, maintaining research participants, heterogeneity issues, and implementation fidelity. About half of studies in this review reported positive program effects on their targeted outcomes such as Well-being and Health for PWD on improving quality of life, neuropsychiatric symptoms and agitation; cognitive stimulation therapy on QoL, neuropsychiatric symptoms and cognition; and a stepwise multicomponent intervention on neuropsychiatric symptoms, depression and agitation. Conclusions: We found some programs even with a rigorous study design did not produce expected outcomes while other programs with poor designs reported positive outcomes, which necessitates further investigation on the validity of the assessments. Factors such as individual tailored and customized interventions, promoting social interactions, ease of administration and compatibility of interventions, and developing program theory need to be considered when developing nonpharmacological intervention programs.

Purpose: This study examined the trends in domestic research that applied theory to diabetes patients to suggest future directions of nursing practice and research for diabetes patients. Methods: This scoping review followed the Joanna Briggs Institute guidance. The population was diabetes patients; the concept was a research that applied theory and had no limitations in context. Eligible studies were retrieved from electronic databases of RISS, KMbase, KoreaMed, NDSL, NAL, and nine major domestic nursing journals. Of the 509 retrieved articles, 20 studies met the inclusion criteria. Results: The study included the community (57.1%), and the subjects were mainly type 2 diabetes patients (42.9%). The Information-Motivation-Behavior skills (IMB) model was the most applied theory (36.4%). The theories were primarily from psychology disciplines (72.7%) and predominantly applied as a conceptual framework of the study (55%). Conclusion: The studies that applied theory were conducted mainly in the community. The IMB model was the most applied theory, and the theory was most applied as the conceptual framework. Efforts to close the theory-practice gap and further studies on developing nursing interventions based on theory and verifying their effectiveness are needed to improve nursing practice and study for diabetic patients.

This study aims to understand the antecedents and consequences of flow experience in online movie information sharing behavior of young Chinese moviegoers residing in Korea to explore a potential market. We followed the Stimulus-Organism-Response (S-O-R) theory and flow theory approaches for developing measures of constructs and investigated previous related studies. This study collected 186 data from Chinses students who attend Korean university. Statistical analysis revealed that information seeking behavior and telepresence are related to online flow experience. In addition, the online flow experience affected consumer satisfaction and information sharing behavior. Flow experience also has been predicted the mediation effect between stimulus information seeking behavior, telepresence and satisfaction and information sharing behavior. Our research findings offer insights for marketers in the movie distribution business who are interested in a better understanding of the behaviors of Chinese moviegoers residing in Korea
