Published: December 2021

Background
Healthcare contexts are witnessing a growing use of applications to support clinical processes and to communicate between peers and with patients. An increasing number of hospital professionals use instant-messaging applications such as WhatsApp in their daily work. Previous research has mainly focused on the advantages and risks of WhatsApp usage in different clinical settings, but limited evidence is available about whether and how individual and organizational determinants can influence the use of WhatsApp in hospitals. Moreover, instruments to explore this phenomenon are lacking. A theoretical four-factor model based on the ‘Technology Acceptance Model’ and the Institutional Theory, guided the development of a new measure of the individual and institutional determinants of WhatsApp usage in hospitals.

Aim
To develop and psychometrically test the questionnaire ‘Digital Innovation Adoption in Hospitals’.

Method
A panel of researchers and clinical experts generated an initial pool of 35 items by identifying and adapting items from existing measures. These items were assessed for content and face validity by fourteen experts. The final 28-item ‘Digital Innovation Adoption in Hospitals’ questionnaire comprising four sections (Perceived risks, Perceived usefulness, Regulative factors and Normative factors) was administered online to nurses and physicians. Construct validity was tested through confirmatory factor analysis.

Results
The sample included 326 hospital nurses and physicians. The theoretical four-factors model was confirmed and the confirmatory factor analysis yielded acceptable fit indexes. The correlations between the factors were significant and ranged from -0.284 to 0.543 (p < .01). Reliability in terms of internal consistency was satisfactory with Cronbach’s alpha coefficient ranging from 0.918–0.973.

Conclusion
This study is the first to provide a validated tool to evaluate the use of WhatsApp in hospitals. The new instrument shows reasonable psychometric properties and is a promising and widely applicable measure of factors that influence the use of WhatsApp in hospitals.

The Ordinary Least Squares (OLS) is one of the most commonly used method to estimate linier regression parameters. If there is a violation of assumptions such as multicolliniearity especially coupled with the outliers, then the regression with OLS is no longer used. One method can be used to solved the multicollinearity and outliers problem is Ridge Robust Regression. Ridge Robust Regression is a modification of ridge regression method used to solve the multicolliniearity and using some estimators of robust regression used to solve the outlier, the estimator including : Maximum likelihood estimator (M-estimator), Scale estimator (S-estimator), and Method of moment estimator (MM-estimator). The case study can be used with this method is data with multicollinearity and outlier, the case study in this research is poverty in Central Java 2020 influenced by life expentancy, unemployment number, GRDP rate, dependency ratio, human development index, the precentage of population over 15 years of age with the highest education in primary school, mean years school. The result of estimation using OLS show that there is a multicollinearity and presence an outliers. Applied the ridge robust regression to case study prove that ridge robust regression can improve parameter estimation. The best ridge robust regression model is Ridge Robust Regression S-Estimator. The influence value of predictor variabels to poverty is 73,08% and the MSE value is 0,00791.

Authors: Fatmarizka Tiara , Ramadanty Raudhatus Shofy , Khasanah Dini Afriani 
Published: December 2021

Introduction: Around 50-70% of pregnant women have reported pregnancy-related back pain during the second and third trimesters of pregnancy. Physical and physiological aspects during pregnancy might affect the quality of life (QoL) of pregnant women, and the problems due to the alteration can be seen in how they run their daily activities. The effect of LBP in pregnancy on the QoL among pregnant women must be known to avoid the pain that affects pregnant women’s activities and well-being. The aim of this study is to review the relationship between low back pain and the QoL during pregnancy.Methods: Using the search terms via PubMed and Google Scholar, seven cross-sectional studies have met the inclusion criteria and included for further analysis. The appraisal tool for Cross-Sectional Studies (AXIS) is used to assess the quality of the included studies including the risk of bias.Results: The findings show that LBP in pregnancy affects the level of quality of life such as sleep quality and sexual activity, limits the activities and productivities, and even make physical disability among pregnant women. The 75-90% was of the range score obtained from the AXIS critical appraisal.Conclusions: This review mentioned those pregnant women with PRBP had decreased QoL during and after childbirth, so the awareness of health professionals needs to be improved.

Published: December 2021

Introduction: The importance of personal hygiene in preventing the spread of infection cannot be underestimated. Handwashing is an essential aspect of personal hygiene, especially among children. This study aimed to explore primary school students' hygiene in rural and remote areas in the Kupang regency. Methods: This study was conducted as a part of the end line evaluation of the MEMBACA II project. Teachers from four primary schools in three villages were purposively selected to participate in this study. The teachers were recruited from the participant schools of the MEMBACA II Project. Data was collected using phone interviews. Data were analyzed using inductive thematic analysis. Results: In total, there were 31 participants across four primary schools interviewed. The participants consisted of teachers, village leaders, village reading camp facilitators, and school supervisors. Participants were recruited as a proxy for providing information about students' hygiene. There were three themes identified as a result of the data analysis. The first theme is an improvement in children’s hygiene behavior. The second theme is the benefit of the little doctor program in children’s hygiene practices. The third theme challenges in children’s hygiene promotion and education. Overall, children were used to handwashing practices. They understood the importance of handwashing, especially during the Covid-19 pandemic. They were also aware of four essential times of handwashing. However, the adults perceived the need for handwashing equipment and access to clean water were the main challenges to maintaining students' hygiene. Conclusion: The study demonstrated the significance of regularly teaching children about handwashing in making handwashing habits among these youngsters. A continuing provision of health literacy and access to clean water is required to maintain hygiene behavior
Positronium as a biomarker of hypoxia
Authors: Moskal Paweł , Stępień Ewa Ł. 
Published: December 2021

Abstract
In this review article, we present arguments demonstrating that the advent of high sensitivity total-body PET systems and the invention of the method of positronium imaging, open realistic perspectives for the application of positronium as a biomarker for in-vivo assessment of the degree of hypoxia. Hypoxia is a state or condition, in which the availability of oxygen is not sufficient to support physiological processes in tissue and organs. Positronium is a metastable atom formed from electron and positron which is copiously produced in the intramolecular spaces in the living organisms undergoing positron emission tomography (PET). Properties of positronium, such as e.g., lifetime, depend on the size of intramolecular spaces and the concentration in them of oxygen molecules. Therefore, information on the partial pressure of oxygen (pO2) in the tissue may be derived from the positronium lifetime measurement. The partial pressure of oxygen differs between healthy and cancer tissues in the range from 10 to 50 mmHg. Such differences of pO2 result in the change of ortho-positronium lifetime e.g., in water by about 2–7 ps. Thus, the application of positronium as a biomarker of hypoxia requires the determination of the mean positronium lifetime with the resolution in the order of 2 ps. We argue that such resolution is in principle achievable for organ-wise positronium imaging with the total-body PET systems.
Emergence of synaptic organization and computation in dendrites
Authors: Kirchner Jan H. , Gjorgjieva Julijana 
Published: December 2021

Abstract
Single neurons in the brain exhibit astounding computational capabilities, which gradually emerge throughout development and enable them to become integrated into complex neural circuits. These capabilities derive in part from the precise arrangement of synaptic inputs on the neurons’ dendrites. While the full computational benefits of this arrangement are still unknown, a picture emerges in which synapses organize according to their functional properties across multiple spatial scales. In particular, on the local scale (tens of microns), excitatory synaptic inputs tend to form clusters according to their functional similarity, whereas on the scale of individual dendrites or the entire tree, synaptic inputs exhibit dendritic maps where excitatory synapse function varies smoothly with location on the tree. The development of this organization is supported by inhibitory synapses, which are carefully interleaved with excitatory synapses and can flexibly modulate activity and plasticity of excitatory synapses. Here, we summarize recent experimental and theoretical research on the developmental emergence of this synaptic organization and its impact on neural computations.
Negotiating the Duplexity of Ethnographic Relations: Taking a Symmetrical Approach to Interlocutors “in” and “beyond” Science
Authors: Czerny Sarah 
Published: December 2021

Abstract
In this paper, I raise the question of how we can, as anthropologists, take a balanced or symmetrical approach in our research in situations where our interlocutors have different relations with scientific knowledge. I describe how in my research on raw milk consumption in Croatia, some of my interlocutors were people working in the scientific production of knowledge, and others were consuming raw milk where they did not account for this knowledge. I explain how it was a challenge to consider both types of approach in an equal way because of my own relation to the scientific production of knowledge. I argue this is because of the duplex relation we have with our interlocutors who work in science: a collegial relation and an ethnographic one. As I show, this is a point that has been made in some of the literature on vaccination (e.g. Drążkiewicz Grodzicka, 2021), as well as one that has been discussed elsewhere (e.g. Nadasdy, 2007). I then consider these issues through Hufford’s (2020, 2008) idea of methodological symmetry, where I argue that it is in the “field” where relations are set up asymmetrically. Therefore, I argue that we need to think very carefully about how these relations unfold in practice during our fieldwork, and not just later on when we are analysing them.

Effect of Prosthodontic Rehabilitation on Perioral Units in Edentulous Patients
Authors: ÇELEBİ Hakkı , ALAN Raif , KARTAL Elif 
Published: December 2021

Background: Complete edentulous patients experience loss in fundamental mastication functions, the progressive absorption of the alveolar bone, and variation in facial appearance. Complete dentures (CD) fundamentally target edentulous patients and not only increase functionality but also restore the appearance of the face. This study aims to evaluate the effect of rehabilitation with removable CD on perioral wrinkles in complete edentulous patients, in line with growing aesthetic demand.
Methods: Patients who had CD rehabilitation performed due to total edentulism were photographed before and after rehabilitation from the same angles to evaluate the perioral soft tissue changes. The photographs were scored using verified ranking scales and through evaluation by two observers. To evaluate the repeatability of the scales, measurements were repeated with the same method one month later.
Results: When the effect of prosthetic rehabilitation administered successfully on perioral aesthetics and lip volume was analyzed, a significant improvement was observed in all other parameters evaluated, except for in the labiomental crease. The improvement in the labiomental crease was not statistically significant. In addition, re-measurement reliability was high (≥0.80) for all four perioral units (nasolabial folds, corners of mouth, labiomental crease and upper radial lip). In addition, all correlations were statistically significant (p
Optical properties of semiconductor “anisotropic” quantum dot
Authors: Lukiyanets B.A. , Matulka D.V. 
Published: December 2021

The optical properties of an “anisotropic” semiconductor nanodot – a nanoscale object in the form of a rectangular parallelepiped - with sides a ≠ b ≠ c are considered. Such dimensions are closely related to the values of the effective masses of the electron. The analysis of the spectral dependence of the absorption coefficient a(w) under different degrees of "anisotropy" and under different polarizations of the electromagnetic wave is carried out. The cases of the most intense optical transitions, i.e. between electronic states separated by the Fermi level, are analyzed. The obtained results indicate that 1) a(w) is of line structure, and 2) the positions of the peaks of a(w) in identical optical transitions in the isotropic nanodot and in the “anisotropic” ones coincide qualitatively. However, different masses in the “anisotropic” nanodot lead to a shift to the left or right of the peaks relative to identical peaks in the isotropic nanodot with simultaneous splitting of its degenerate peaks. Such shifts and their magnitudes are determined both by the degree of anisotropy (i.e. by the ratio between the effective masses), and by the polarization of light. It is pointed out that modern achievements in the creation of ordered semiconductor materials with nanoobjects of different shapes and sizes in nanostructures allows us to consider polarized electromagnetic wave as an effective factor in achieving the desired physical characteristics.

By the method of rapid radiation heating (at a speed of 20-25 K/s) of Au and Ag films with a thickness of 4-35 nm to temperatures of 573-693 K in air and in the process of vacuum deposition of silver on heated (up to 700 K at a heating rate of 10 K/s ) glass substrates formed Au and Ag NPs arrays with nanoparticle sizes from several tens to hundreds of nanometers, the position λSPR of which is in the range of 520-597 nm for Au NPs and 424-509 nm for Ag NPs. It is established that the average size of nanoparticles depends on the thickness of gold and silver films and the annealing temperature. The results testify that glass substrates with arrays of randomly distributed gold NPs can be used as effective SERS-substrates for the investigation of Raman spectra of nanosized (50-100 nm) chalcogenide films.

Authors: Hinostroza Vargas Machuca Cristhian David , Rivera Riofano Pablo Héctor 
Published: December 2021

Los materiales topológicos permiten el transporte de cargas polarizadas a través de estados de borde y superficie en sistemas 2D y 3D. Estos estados de borde y superficie están protegidos por la simetría de orden topológico basada en el acoplamiento espín-órbita y en la invarianza sobre el operador de reversión temporal. El propósito principal de este trabajo es analizar la evolución del estado de superficie en las aleaciones HgTe y CdTe observando la inversión de bandas y el efecto de los orbitales atómicos d en la inversión de las bandas y la intensidad del acoplamiento espín-órbita. Los resultados fueron obtenidos usando la teoría de funcionales de densidad con aproximación local de densidad de espín y la corrección de Hubbard (SLDA+U) considerando efectos relativistas y polarización de espín.
