Bacterial cellulose is a sustainable biomaterial produced by Acetobacter xylinum, which has a self-synthesizing property to grow in any shape. The purpose of the study was to diagnose the current status of bacterial cellulose in textile development and produce innovative cultivation techniques in order to cater to different usages and forms of bacterial cellulose textiles for a variety of garment styles. The new tailor-shaped cultivation techniques not only improve the environmental values of this material but also further promote its production method as a sustainable practice. This organic material is able to be cultivated in any desirable garment panel shape, with no cutting and less textile waste. Two different types of tailor-shaped cultivation techniques called contacting surface-blocking cultivation and panel-shaped cultivation were developed. With the self-synthesizing property, natural biodegradable bacterial cellulose can shed light on the development of new sustainable textile materials and manufacturing practices in the future.

The fascia can be defined as a dynamic highly complex connective tissue network composed of different types of cells embedded in the extracellular matrix and nervous fibers: each component plays a specific role in the fascial system changing and responding to stimuli in different ways. This review intends to discuss the various components of the fascia and their specific roles; this will be carried out in the effort to shed light on the mechanisms by which they affect the entire network and all body systems. A clear understanding of fascial anatomy from a microscopic viewpoint can further elucidate its physiological and pathological characteristics and facilitate the identification of appropriate treatment strategies.

While virtually all animals show certain abilities for regeneration after an injury, these abilities vary greatly among metazoans. Porifera (Sponges) is basal metazoans characterized by a wide variety of different regenerative processes, including whole-body regeneration (WBR). Considering phylogenetic position and unique body organization, sponges are highly promising models, as they can shed light on the origin and early evolution of regeneration in general and WBR in particular. The present review summarizes available data on the morphogenetic and cellular mechanisms accompanying different types of WBR in sponges. Sponges show a high diversity of WBR, which principally could be divided into (1) WBR from a body fragment and (2) WBR by aggregation of dissociated cells. Sponges belonging to different phylogenetic clades and even to different species and/or differing in the anatomical structure undergo different morphogeneses after similar operations. A common characteristic feature of WBR in sponges is the instability of the main body axis: a change of the organism polarity is described during all types of WBR. The cellular mechanisms of WBR are different across sponge classes, while cell dedifferentiations and transdifferentiations are involved in regeneration processes in all sponges. Data considering molecular regulation of WBR in sponges are extremely scarce. However, the possibility to achieve various types of WBR ensured by common morphogenetic and cellular basis in a single species makes sponges highly accessible for future comprehensive physiological, biochemical, and molecular studies of regeneration processes.

Application of biomimetics has expanded progressively to other fields in recent years, including urban and architectural design, scaling up from materials to a larger scale. Besides its contribution to design and functionality through a long evolutionary process, the philosophy of biomimetics contributes to a sustainable society at the conceptual level. The aim of this review is to shed light on trends in the application of biomimetics to architectural and urban design, in order to identify potential issues and successes resulting from implementation. In the application of biomimetics to architectural design, parts of individual “organisms”, including their form and surface structure, are frequently mimicked, whereas in urban design, on a larger scale, biomimetics is applied to mimic whole ecosystems. The overall trends of the reviewed research indicate future research necessity in the field of on biomimetic application in architectural and urban design, including Biophilia and Material. As for the scale of the applications, the urban-scale research is limited and it is a promising research which can facilitate the social implementation of biomimetics. As for facilitating methods of applications, it is instrumental to utilize different types of knowledge, such as traditional knowledge, and providing scientific clarification of functions and systems based on reviews. Thus, interdisciplinary research is required additionally to reach such goals.

This study examined the structural constraints to disclosure of children's positive serostatus among informal caregivers to family and nonfamily members in Togo. It drew on two data sources, one qualitative and the other quantitative. Qualitative data showed that caregivers cautiously disclosed child's positive serostatus for fear of being stigmatized and discriminated against as well as to protect the children from being stigmatized. Binary regression analyses revealed that different factors influenced reasons for disclosure of a child's serostatus. For instance, while caregivers' serostatus and number of children significantly influenced disclosure for financial support, disclosure of a child's serostatus for spiritual support was strongly affected by education and religion. These results shed light on factors and reasons for disclosure among caregivers. This knowledge is important because different types of programs and advice should be given to caregivers with specific reason(s) for disclosure instead of creating a “one-size-fits all” program for all caregivers.

ABSTRACTBacterial cellulose (BC) has a range of structural and physicochemical properties that make it a particularly useful material for the culture of bacteria. We studied the growth of 14 genera of bacteria on BC substrates produced byAcetobacter xylinumand compared the results to growth on the commercially available biopolymers agar, gellan, and xanthan. We demonstrate that BC produces rates of bacterial cell growth that typically exceed those on the commercial biopolymers and yields cultures with higher titers of cells at stationary phase. The morphology of the cells did not change during growth on BC. The rates of nutrient diffusion in BC being higher than those in other biopolymers is likely a primary factor that leads to higher growth rates. Collectively, our results suggest that the use of BC may open new avenues in microbiology by facilitating bacterial cell culture and isolation.

A novel bacterial cellulose (BC) composite (carboxymethylated-bacterial cellulose, CM-BC) was synthesized by Acetobacter xylinum by adding water-soluble carboxymethylated cellulose (CMC) in the culture medium. FTIR results showed that CM-BC is obtained by the incorporation of CMC in the network of BC. Water-holding capacity and water vapor transmission rates (WVTR) of CM-BC and BC are determined. The WVTR of CM-BC is comparable to that of BC, but the water-holding capacity of CM-BC is improved compared with BC. Tensile strengths measurement results showed that the fracture stress of CM-BC is higher than that of BC, indicating that CM-BC have more potential wound dressing applications than BC.

This study tends to shed light on early childhood care and education (ECCE) institutions with special reference to kindergartens in Fukuoka, Japan. The choice of the topic for study was derived by the importance of ECCE in children’s life and huge economic growth of Japan after worst effects of world war-II, which are thought to be linked with the education that children receives in Japan. The study is limited to four kindergartens in Fukuoka City and observations made for the study refers to 2018. Herein, different types of institutions providing ECCE, their infrastructural set-up, activities, along with curriculum are discussed. At the end, issues and challenges of ECCE system in Japan are discussed. It has been observed that the infrastructural facility and nature of activities are of high quality. Each and every care is being taken to inculcate habits, as well as to maintain physical and intellectual growth of children. The children seem to be highly happy and enjoy learning via various activities in these schools. It is clear that the devised policies on education and care of children are implemented in full spirit.

AbstractThe main aim of this article is to start a discussion of social pattern, a term that is commonly used in sociology but not specified or defined. The key question can be phrased as follows: Is it possible to transform the notion of social pattern from its current status in sociology as a proto-concept into a fully worked out concept? And if so, how can this be done? To provide material for the discussion we begin by introducing a few different types of patterns that are currently being used (patterns in nature, cultural patterns, statistical patterns, and computationally generated patterns). This is followed by a suggestion for what a strictly sociological concept of social pattern may look like. A useful and theoretically solid concept of social pattern can in our view be constructed by basing it on Weber’s concept of social action. This means that both the behavior of the actors and the meaning these invest their behavior with must be taken into account. The article ends with a brief discussion of how to use the concept of social patterns in an effective way and what may endanger such a use.
