Purpose: This descriptive study aims to analyze the effects of the satisfaction level in the relationship between mother-in-law and daughter-in-law, conflicts between them, acculturative stress and stress coping strategies on elderly depression in multi-cultural families. Methods: The survey was conducted on 89 mothers-in-law, aged 65 or older, in multi-cultural families with a foreign daughter-in-law. Data were collected through structured questionnaires, and then were used to conduct t-test, ANOVA, correlation and multiple regression analyses using the statistical program SPSS 21.0. Results: This study found several factors contributing to depression of mothers-in-law in multi-cultural families. Those factors include living alone without a spouse, poor health, a high level of perceived discrimination and a passive reaction in terms of stress coping strategies. Conclusion: A sense of discrimination perceived by the mothers-in-law having a foreign daughter-in-law implies that the people around them and the community should make efforts to reject distorted perspectives and remove prejudice against foreign daughters-in-law. In addition, the mothers-in-law should receive education and training to use more active and positive stress coping strategies in a stressful situation with the foreign daughter-in-law.

In this paper, we suggest three-dimensional information extraction map system using integral imaging technique. Integral imaging can record multiple elemental images with different perspectives using a 2D image acquisition device with lenslet array. Using these images, integral imaging can obtain 3D information and display 3D image. In this paper, the position difference between elemental images can be obtained using summation of absolute difference (SAD), and then 3D information can be extracted. Therefore, this technique can find the height information of 3D objects.

Plural governance system in which firms use vertical integration and market governance simultaneously are widely used across various marketing context. Typical examples of plural governance include franchise systems, in which firms own and operate some unit themselves while licensing the operation of some of their units to franchisees. Despite many scholars have attempted to explore the structure of plural governance over decades, there are few insights into its determinants. In this study, we examine the relationship between the proportion of outlets franchised and several franchisor's characteristics based on the perspectives of transaction cost analysis, resource scarcy theory and agency theory. Using franchisor data in Korean Franchise Disclosure Document over the 2006-2009 period, we test the effect of franchisor size, system growth rate, franchise fee, initial investment, and risk sharing on the proportion of outlets franchised. Except for the effect of system growth rate, the results of a series of multiple regression analysis supported the negative effects of franchisor size, franchise fee, initial investment and risk sharing on the proportion of outlets franchised.

Recent advances in cell biological and genetic researches have revealed that mitochondrial morphology is highly dynamic and regulated by multiple molecular factors including dynamin-related proteins (DRPs). Considering that the mitochondria play critical roles in the cellular metabolism via ATP synthesis, calcium homeostasis in cooperation with endoplasmic reticulum, and apoptosis, the failure of mitochondrial dynamics is infrequently related to the failure in the normal growth and cellular integrity. In this respect, alteration of mitochondrial dynamics may greatly affect the development of nervous system. In this short review, we discussed molecules involved in the control of mitochondrial dynamics, and provide some perspectives on their significance in the neuronal development.

Cancer is the tissue complex consisted with heterogeneous cellular compositions, and microenvironmental cues. During the various stages of cancer initiation, development, and metastasis, cell-cell interactions as well as cell-extracellular matrix play major roles. Conventional cancer models both 2-dimensional and 3-dimensional (3D) present numerous limitations, which restrict their use as biomimetic models for drug screening and fundamental cancer biology studies. Recently, bioprinting biofabrication platform enables the creation of high-resolution 3D structures. Moreover this platform has been extensively used to model multiple organs and diseases, and this versatile technique has further found its creation of accurate models that figure out the complexity of the cancer microenvironment. In this review we will focus on cancer biology and limitations with current cancer models and we discuss vascular structures bioprinting that are critical to the construction of complex 3D cancer organoids. We finally conclude with current literature on bioprinting cancer models and propose future perspectives.

Purpose: This study examined the knowledge and perception of hospice-palliative care and terminal care stress among pediatric nurses, and the relationships among these variables. Methods: In this descriptive research study, 154 pediatric nurses who experienced terminal care at least once were surveyed. This study used three scales, including the Palliative Care Quiz for Nursing (PCQN), Perception of Hospice-Palliative Care, and Terminal care stress. Data analyses using SPSS 22.0 included descriptive statistics, independent t-test, one-way ANOVA, Mann-Whitney U test, Pearson's correlation coefficient, and stepwise multiple linear regression. Results: Terminal care stress experienced by the pediatric nurses was significantly related to the perception of hospice-palliative care; the hospice-palliative care education program enhanced the knowledge and perception of hospice-palliative care. Conclusion: Hospice-palliative care education programs should be developed and provided for pediatric nurses to improve pediatric hospice-palliative care. Additionally, further research on this topic is required because the present results are inconsistent with previous and current researches.

This study aims to investigate the status quo and identify the challenges and benefits of the digital transformation in the context of small and medium-sized enterprises (SMEs) in Vietnam. The six participating SMEs were purposely contacted, and they were either nominated for, or received the Vietnam Digital Awards in 2018, 2019 and 2020, which were held by the Vietnam Digital Communication Association (http://en.vdca.org.vn/). A qualitative research method is adopted, using a semi-structured interview method and a theoretical triangulation of legitimacy, stakeholder and stewardship theories to facilitate the investigation. This research tries to identify the current challenges and benefits for digital transformation of SMEs in Vietnam, based on perception and experience from business leaders and managers from six SMEs in Vietnam. The findings of this study reveal that besides the recent challenges for digital transformation, participants also experienced and shared their perspectives regarding the benefits received from the digital transformation journey of their organization, which varied from (i) improve operational as well as business functions; (ii) liberate staffs and managers from daily work and allows them to focus on decision-making tasks; (iii) enable solutions to deal with consequences from the COVID-19 pandemic; (iv) enhance value creation process; and (v) help firms to align with the global business standards.

The trend of globalization has sharpened the debate on interculturality, which scholars examine from different and often conflicting points of view ('content' vs. 'practice', 'culture-specific' vs. 'universal', 'communication (meta)theory' vs. 'communication practice', 'individual' vs. 'collective', etc.). Whereas all these approaches are necessary to describe the multiple dimensions of interculturality, their dichotomous nature does not help to account for its internal complexity, which cannot be dissociated from the connections that exist among all these dimensions. The difficulty posed by the essentialist interpretations that tend to result from these dichotomies is compounded by the fact that in postmodern debates priority has been given to approaches that emphasize individual or collective agency over structural constraints which have to do with political economy or with cultural and linguistic codes and traditions. This paper aims mainly at suggesting that the dissolution of the boundaries that exist between these approaches should be pursued in order to get a fuller and richer approach to their common object of study. After discussing, by way of illustration, content-based and practice-based perspectives, we suggest that one way of getting beyond these dichotomies consists in focusing on the 'interactional' dimension of interculturality, which means laying emphasis on intersubjectivity and, particularly, on the individual subjects considered as members of different cultural communities who strive to transcend their sociocultural boundaries in order to reach harmonious interactions in a world in which inequality and the de-territorialization of people and cultures are central features.

Fashion films with screen limits have a way of changing communication methods through sensorial organs in order to go beyond limits. This study shows that such change is possible if fashion films are based on haptic factors. This study examines haptic factors of fashion films from the three perspectives of filming factors of different shot size, synesthetic, and cinematic screen methods. First, when the subject to be emphasized is enlarging, the observer comes to project themselves to the situation and incurs a haptic sensation. Second, when associating an experience by personal recollection or social customs when more than two senses are stimulated simultaneously, haptic sensations, triggered by multiple senses, takes place. Third, a blurred image shows haptic sensations through inducing observers to see into the meaning of a shot. As a result, the senses of the observer enlarge and enhance a communication ability through absorbing and accepting a fashion film. Furthermore, fashion films are effective in understanding the cultural forms of the age.
