Published: December 2019

Background

Proper device size selection is a crucial step for successful ASD device closure. The current gold standard for device size selection is balloon sizing. Balloon sizing can be tedious, time consuming and increase fluoroscopy and procedure times as well as risk of complications. We aimed to establish a simple and accurate method for device size selection using three-dimensional echocardiographic interrogation of the ASD.This is a prospective observational study conducted over a period of 12 months. All patients underwent 2D TTE, three-dimensional echocardiographic assessment of the IAS and transesophageal echocardiogram. Comparison between echocardiographic variables was done using independent sample t test. Linear correlation was established between three dimensional echocardiographic variables and respective variables of device size and 2D TTE and TEE measurements.

Results

The study included 50 patients who underwent successful ASD device closure with properly sized device. There was no significant difference between 3D ASD maximum diameter and all diameters measured by TTE and TEE. There was a strong positive correlation between device size used for closure and both 3D measured ASD area (r = 0.907, P<0.0001) and 3D measured ASD circumference (r = 0.917, P<0.0001). Two regression equations were generated to determine proper device size where Device size = 10.8 + [3.95 x 3D ASD area] and Device size = [3.85 x 3D ASD circumference] -1.02

Conclusion

Three-dimensional echocardiogram can provide a simple and accurate method for device size selection in patients undergoing ASD device closure using either 3D derived ASD area or ASD circumference

Published: December 2019

Purpose

The portable metabolic analyzer COSMED K5 (Rome, Italy) allows for switching between breath-by-breath (BBB) and dynamic micro-mixing chamber (DMC) modes. This study aimed to evaluate the reliability and validity of the K5 in BBB and DMC at low, moderate, and high metabolic rates.

Methods

Two K5 simultaneously operated in BBB or DMC, whereas (i) a metabolic simulator (MS) produced four different metabolic rates (repeated eight times), and (ii) 12 endurance-trained participants performed bike exercise at 30%, 40%, 50%, and 85% of their individual power output at V˙O2max (repeated three times). K5 data were compared with predicted simulated values and consecutive Douglas bag measurements.

Results

Reliability did not differ significantly between BBB and DMC, whereas the typical error and intraclass correlation coefficients for oxygen uptake (V˙O2), carbon dioxide output (V˙CO2), and minute ventilation (V˙E) ranged from 0.27% to 6.18% and from 0.32 to 1.00 within four metabolic rates, respectively. Validity indicated by mean differences ranged between 0.61% and −2.05% for V˙O2, 2.99% to −11.04% for V˙CO2, and 0.93% to −6.76% for V˙E compared with MS and Douglas bag at low to moderate metabolic rates and was generally similar for MS and bike exercise. At high rates, mean differences for V˙O2 amounted to −4.63% to −7.27% in BBB and −0.38% to −3.81% in DMC, indicating a significantly larger difference of BBB at the highest metabolic rate.

Conclusion

The K5 demonstrated accurate to acceptable reliability in BBB and DMC at all metabolic rates. Validity was accurate at low and moderate metabolic rates. At high metabolic rates, BBB underestimated V˙O2, whereas DMC showed superior validity. To test endurance athletes at high workloads, the DMC mode is recommended.
The Maximum CPR Model: a demographic tool for family planning policy
Authors: Bietsch Kristin , Sonneveldt Emily
Published: December 2019

The Maximum CPR Model (MCM) allows demographers, policy makers, and family planning advocates to determine a country’s highest potential contraceptive prevalence rate (CPR), based on an ideal number of children, demographic life events, and population structure. Understanding the highest potential level of CPR achievable under current circumstances in a population leads to realistic expectations and appropriate policy implementation. Countries with a large gap between current CPR and maximum CPR can focus on removing blocks to contraceptive use, while countries where the maximum potential CPR is near the actual CPR may need to shift their focus to demand generation or postpartum family planning programs. With a focus on equality of access to family planning, MCM produces CPR for all women, regardless of marital status. This paper details the mathematical construction of the MCM. A version of the model is available online for easy use by non-technical audiences in English and French.
India-Bhutan Relationships: Cordial but Concerns Remain
Authors: Ranjan Amit
Published: December 2019

In 2018, India and Bhutan completed 50 years of their diplomatic relationships. For a large number of South Asian observers and commentators, the two countries are considered close to each other, however, there are areas of concern. One of them is India‟s investments in Bhutan‟s hydropower sector. There is a growing disillusionment among a section of the Bhutanese population over India‟s engagements in this sector. This paper looks at the relationships between the two countries and examines the concerns of Bhutanese against India. The author argues that Bhutan is a small but strategically important country for India whose concerns must be satisfactorily addressed by New Delhi.

Published: December 2019

Religious conversion, which includes leaving one’s religion for another religion or change within the same religion, is among the most popular subjects of the psychology of religion and the sociology of religion. This study analyzes via a psychosocial methodology the process before, during, and after a change in the faith of individuals born in an Islamic culture and who distanced themselves from religion for a certain period of their lives. The pool consists of twenty-seven participants. The study employs a qualitative research method and a structured interview technique. The interview is an abridgment of the form created by Köse (1996) designed to focus on the childhood and youth of participants, as well as on their family relationships, identity crises, and changes during or after decision-making processes. Content analysis is applied to the findings. Most participants, who indicated that they had not received formal religious education during childhood, expressed that situations such as getting beat up, being ostracized and come across superstitions led to their religious disgruntlement. Some female participants indicated that they distanced themselves from religion during their youth because of the negative image of women created by cultural and religious values. Participants, particularly males, indicated that they made decisions to recover from their addictions prior to intrareligious conversion process. In addition, intellectual motives come to the forefront in the process of intrareligious conversion; factors such as coming across as good believers and having a religious community are influential. Having made the decision to return to their faith, participants often reported that they enjoy peace and feel special and free

Sequential Learning in Designing Marketing Campaigns for Market Entry
Authors: Moazeni Somayeh , Defourny Boris , Wilczak Monika J.
Published: December 2019

Developing marketing campaigns for a new product or a new target population is challenging because of the scarcity of relevant historical data. Building on dynamic Bayesian learning, a sequential optimization assists in creating new data points within a finite number of learning phases. This procedure identifies effective advertisement design elements as well as customer segments that maximize the expected outcome of the final marketing campaign. In this paper, the marketing campaign performance is modeled by a multiplicative advertising exposure model with Poisson arrivals. The intensity of the Poisson process is a function of the marketing campaign features. A forward-looking measurement policy is formulated to maximize the expected improvement in the value of information in each learning phase. A computationally efficient approach is proposed that consists of solving a sequence of mixed-integer linear optimization problems. The performance of the optimal learning policy over a set of benchmark policies is evaluated using examples inspired from the property and casualty insurance industry. Further extensions of the model are discussed.

Published: December 2019

The present work was aimed to synthesize some novel 2-chloro-N,N-diphenylacetamide derivatives conjugated with various benzaldehydes in multistep synthesis and further to undergo the process of docking on COX-1 and COX-2 enzymes. All the targeted synthesized compounds were subjected to evaluation of analgesic activity using hot plate model. Sophisticate analytical techniques via infrared spectroscopy, NMR, Mass spectroscopy and elemental analysis were employed to characterize the newly synthesized compounds. All the synthesized derivatives were evaluated for their analgesic activity. The synthesized compound AKM-2 (N-(4-(diphenylamino) thiazol-2-yl)-2-((4-((3methylbenzylidene)amino)phenyl)amino)acetamide) exhibited significant analgesic response when comparison was made with diclofenac sodium as standard drug. Molecular docking study was used to discover the possibility of binding site and binding strength of new derivatives of acetamide. The present study offers insight for compound AKM-2, as a new lead compound as analgesic agent because of significant docking and similar amino acid residue. The biological activity performed by in-vivo method confirmed the same.
Simultaneous Immunochromatographic Assay of Several Antibiotics: Modulation of Detection Limits and Working Ranges
Authors: Byzova Nadezhda A. , V. Zherdev Anatoly , Dzantiev Boris B.
Published: December 2019

This paper considers the combination of several immunochemical interactions for multiplex immunochromatographic analysis. It was shown that varying the composition of the gold nanoparticles–antibodies conjugate, its concentration and concentration of the hapten–protein conjugate changes both the maximal binding in the test zone and the range of the determined concentrations of the target analyte. Thus, it becomes possible to compensate for differences in the interaction times for the reagents of different specificities that arise when they are combined on one test strip. These regularities were demonstrated for multiplex analysis of three antibiotics. The developed assay has limits of detection of 10, 500, and 10 ng/mL for chloramphenicol, streptomycin, and ampicillin, respectively. Its working ranges for these three analytes are 0.5–6, 16–250, and 0.4–5 ng/mL. The analysis time is 15 min; the accuracy of the photometric determination of antibiotics in the working ranges is up to 6%.

Authors: Srihanam Prasong , Siripipatthana Patthraporn
Published: December 2019

The factionated extracts of wild grape (Ampelocissus martini Planch.) roots by silica gel chromatography eluting with different solvent systems were firstly prepared, and then were assayed for their phytochemical contents and antioxidant activity. A high level of total phenolic and flavonoid content were found in both crude extract and chromatographic fractions. The ethyl acetate: methanol (75:25 %v/v) fraction had the highest of total phenolic and flavonoid as well as antioxidant activity assessed all methods, except ABTS assay. This indicated that eluting solvents directly affected phytochemical profile and activity. Moreover, the phenolic and flanonoid substances showed highly possitive correlation coefficient (r) to antioxidant activity. This suggested that the wild grape root is a natural source containing high phytochemicals with antioxidant activity which might be used as active ingredient for health supporting.

Published: December 2019

The purpose of this paper was to synthesis new mixed-ligand Cu(II) and Co(II) metal complexes utilizing bidentate and tridentate donor hydrazones derivatives as primary ligands and o-vanillin as co-ligand. The obtained compounds were characterized by elemental analysis, Infrared, UV-Vis., 1H-NMR, Mass spectra, molar conductance, thermal analysis and atomic absorption spectroscopy (ASS). Spectroscopic analysis results indicated that the hydrazone ligand (L1) behave as tridentate (ONO) and forms metal complexes having distorted square planar geometry. While the ligands (L2, L3 AND L4) behave as bidentate (NO) and forms metal complexes having octahedral geometry around the central metal atoms. The antimicrobial potentials were assessed for the ligand (L2) and its metal complexes only and were screened against six types of bacterial strains and one fungal strain. The antimicrobial activities results of the tested compounds showed enhanced activity of the complexes over their parent ligands.

The anticancer activity of AgNps shows positive activity on HeLa cell.
Does time to surgery affect patient-reported outcome in proximal humeral fractures? A subanalysis of the PROFHER randomized clinical trial
Authors: Norman John G. , Brealey Stephen , Keding Ada , Torgerson David , Rangan Amar
Published: December 2019

Aims

The aim of this study was to explore whether time to surgery affects functional outcome in displaced proximal humeral fractures

Methods

A total of 250 patients presenting within three weeks of sustaining a displaced proximal humeral fracture involving the surgical neck were recruited at 32 acute NHS hospitals in the United Kingdom between September 2008 and April 2011. Of the 125 participants, 109 received surgery (fracture fixation or humeral head replacement) as per randomization. Data were included for 101 and 67 participants at six-month and five-year follow-up, respectively. Oxford Shoulder Scores (OSS) collected at six, 12, and 24 months and at three, four, and five years following randomization was plotted against time to surgery. Long-term recovery was explored by plotting six-month scores against five-year scores and agreement was illustrated with a Bland-Altman plot.

Results

The mean time from initial trauma to surgery was 10.5 days (1 to 33). Earlier surgical intervention did not improve OSS throughout follow-up, nor when stratified by participant age (< 65 years vs ≥ 65 years) and fracture severity (one- and two-part vs three- and four-part fractures). Participants managed later than reported international averages (three days in the United States and Germany, eight days in the United Kingdom) did not have worse outcomes. At five-year follow-up, 50 participants (76%) had the same or improved OSS compared with six months (six-month mean OSS 35.8 (SD 10.0); five-year mean OSS 40.1 (SD 9.1); r = 0.613). A Bland-Altman plot demonstrated a positive mean difference (3.3 OSS points (SD 7.92)) with wide 95% limits of agreement (-12.2 and 18.8 points).

Conclusion

Timing of surgery did not affect OSS at any stage of follow-up, irrespective of age or fracture type. Most participants had maximum functional outcome at six months that was maintained at five years. These findings may help guide providers of trauma services on surgical prioritization. Cite this article: Bone Joint J 2020;102-B(1):33–41

Published: December 2019

Aims

The purpose of this study was to report the long-term results of extendable endoprostheses of the humerus in children after the resection of a bone sarcoma.

Methods

A total of 35 consecutive patients treated with extendable endoprosthetic replacement of the humerus in children were included. There were 17 boys and 18 girls in the series with a median age at the time of initial surgery of nine years (interquartile range (IQR) 7 to 11).

Results

The median follow-up time was 10.6 years (IQR 3.9 to 20.4). The overall implant survival at ten years was 75%. Complications occurred in 13 patients (37%). Subluxation at the proximal humerus occurred in 19 patients (54%) but only six (17%) were symptomatic. Subluxation was seen more commonly in children under the age of nine years (86%) than in those aged nine years or more (33%) (p = 0.002). Implant failure occurred in nine patients (26%): the most common cause was aseptic loosening (four patients, 11%). Lengthening of the implant was carried out in 23 patients (66%). At final follow up, three patients had a limb that was shortened by 5 cm or more. The mean Musculoskeletal Tumor Society (MSTS) functional score was 79% (73% to 90%).

Conclusion

Extendable endoprosthetic replacement is a reliable method of reconstructing humerus after excision of a bone sarcoma. Children who are less than nine years old have a high risk of subluxation. Cite this article: Bone Joint J 2020;102-B(1):64–71
O lugar dos objetos de ensino nos livros didáticos de Português do Ensino Fundamental II: alterações, deslocamentos e permanências ao longo dos tempos
Authors: Cargnelutti Joceli
Published: December 2019

As pesquisas envolvendo livros didáticos procuram lançar sobre esse objeto diferentes olhares: alguns com tons prescritivos, críticos ou de denúncia; outros mais investigativos. No entanto, o importante é lançar um olhar diferente, que o investigue, descreva, compreenda, que se lance do lugar de uma história e de uma sociologia do ensino. É necessário que se busque uma perspectiva sócio-histórica do livro didático (Soares, 1996). Na tentativa de melhor conhecer a constituição do ensino de língua portuguesa, via livro didático, busco, neste artigo, investigar os objetos de ensino selecionados nas unidades didáticas de coleções de livros didáticos do Ensino Fundamental II, publicados antes e na vigência do Programa Nacional do Livro Didático (PNLD; verificar a ênfase dada a cada objeto de ensino, nas diferentes coleções, bem como pontuar as permanências, as alterações e os deslocamentos  ocorridos, nas unidades didáticas, a partir da seleção dos objetos de ensino. Para tanto, a pesquisa se sustenta na perspectiva teórica sócio-histórica, a qual permite compreender a unidade didática a partir de um processo histórico, e o livro didático enquanto um dos instrumentos responsáveis por assegurar a aquisição dos saberes e das competências julgados indispensáveis à inserção das novas gerações na sociedade (Soares 1996). O corpus da pesquisa é constituído por obras didáticas publicadas antes da vigência do PNLD (período das décadas de 1960, 1970 e 1980) e na vigência do Programa (coleções de 1999, 2002, 2005, 2008 e 2011). O que foi possível depreender, a partir dos elementos, é que os livros didáticos são um sinalizador dos processos de permanência, de alteração e de deslocamentos no ensino de língua de Língua Portuguesa.
Literatura Latino-americana contemporânea: perspectivas desconstrucionistas e decoloniais de heróis - projetos de leitura crítica
Authors: Klock Ana Maria , Mendez Hugo Eliecer Dorado
Published: December 2019

A figura de Simón Bolívar tem sido reconfigurada, na literatura, a partir de diversas perspectivas que ora convergem com o discurso oficial da história ora divergem em distintos níveis e com distintas intenções ideológicas. A relevância dos feitos do Libertador transcende até os dias atuais e o impacto do legado bolivariano – de luta e resistência, mas, também, de corrupção e autoritarismo – repercute nos cenários nacionais dos países destas terras e deveria chegar ao espaço da sala de aula. Igualmente ocorre com a figura histórica do Imperador do Brasil: D. Pedro I. Na literatura contemporânea latino-americana das últimas décadas encontramos romances híbridos de história e ficção que, por meio de singulares estratégias discursivas, narrativas e escriturais, arquitetam uma figura de Bolívar integralmente desconstruída, abandonando qualquer tipo de indulgência outorgada a respeito dos seus feitos mais questionáveis. Uma dessas obras é escrita por Herbert Morote, pesquisador e literato peruano, La visita de Bolívar (2018). Tal processo também ocorre com D. Pedro I na obra Galantes memórias e admiráveis aventuras do virtuoso conselheiro Gomes, o Chalaça (1994), de Roberto Torero. No presente estudo buscamos, por meio da análise estética e discursiva dessas obras, compreender o processo de desmistificação e desconstrução do qual as figuras históricas são foco para revelar a importância destas obras na trajetória formativa de um leitor crítico. Evidenciamos, também, como esse processo de revisão e ressignificação histórica aponta para novos caminhos dentro dos estudos decoloniais, visando a uma reestruturação ideológica e social no nosso continente. Para tanto, apoiamo-nos nos pressupostos de Mignolo (2007), Fleck (2017) e Menton (1993), entre outros pesquisadores nas áreas da teoria decolonial, do romance histórico na América Latina e dos processos de ressignificação da história pela literatura contemporânea.
Simultaneous retrieval of particle size and refractive index by extended interferometric particle imaging technique
Authors: Qieni Lu , Zixuan Li , Chunshuai Fu , Hao Liu
Published: December 2019

A method is presented for simultaneously inferring both the refractive index and the size of a particle with extended interferometric particle imaging technique. The optical system of extended IPI with opposite two-sheet illumination at dual scattering angles is laid out for the experiment. The size of a particle is evaluated by the interference fringe recorded at the scattering angle of 90°, which is from the two reflected lights with two counter-propagating sheet illuminations. And then the refractive index is calculated by the fringe pattern recorded in the side scattering angle region with one of two-sheet illumination when combined with droplet size determined. Experiments on the polystyrene microsphere and water droplet suggest that the method presented herein is promising for many relevant applications, such as fuel combustion and environmental monitoring, in accurately measuring both the particle size and its refractive index.
Purification of the residual entanglement
Authors: Zhou Lan , Zhong Wei , Sheng Yu-Bo
Published: December 2019

Entanglement purification is an indispensable ingredient in extended quantum communication networks and usually determines the efficiency and communication rate of quantum communication protocols. Different from all existing entanglement purification protocols (EPPs) where two or more copies of low quality mixed entangled states are selected from the same ensemble, here we describe a general and optimal EPP for arbitrary initial mixed states from different ensembles. We show that the successful operation of EPP may not obtain a higher fidelity mixed state, while the discarded source pair, which is usually regarded as a failure in existing EPPs, may have residual entanglement and can be reused to increase the yield of entanglement purification. We give the criterions of both the successful purification to obtain a higher fidelity mixed state and the existence of residual entanglement. Moreover, we reveal that entanglement purification procedure causes some entanglement loss. Finally, we provide an optimal approach to reduce the entanglement loss. This approach can also be used to increase the yield of entanglement purification. Our EPP may have potential application in long-distance quantum communications.

Published: December 2019

We present an efficient and robust source of photons at the 87Rb D1-line (795 nm) with a narrow bandwidth of δ = 226(1) MHz. The source is based on non-degenerate, cavity-enhanced spontaneous parametric down-conversion in a monolithic optical parametric oscillator far below threshold. The setup allows for efficient coupling to single mode fibers. A heralding efficiency of ηheralded = 45(5) % is achieved, and the uncorrected number of detected photon pairs is 3.8 × 103/(s mW). For pair generation rates up to 5 × 105/s, the source emits heralded single photons with a normalized, heralded, second-order correlation function

Published: December 2019

Neste trabalho é estudada a propagação de fissuras e ruptura em misturas asfálticas através do ensaio de flexão semicircular. Trincamentos que surgem nos revestimentos asfálticos revelam-se como um dos principais danos que afetam diretamente a serventia e qualidade dos pavimentos flexíveis. Esta pesquisa busca contribuir para a análise da resistência ao trincamento, bem como propagação do trincamento até a ruptura de misturas asfálticas onde são utilizados três diferentes tipos de ligantes. Para este fim empregou-se o ensaio de flexão em amostra semicircular com fenda, estático (EEFAS) e dinâmico (EDFAS). Foram analisadas três composições, dosadas pelo método Superpave: uma com cimento asfáltico de petróleo (CAP), outra com asfalto modificado por polímero (AMP) e a terceira com asfalto borracha (AB), denominadas, respectivamente, como misturas A, B e C. Os resultados indicaram maior rigidez da mistura com AMP, que também apresentou maior vida de fadiga. Por outro lado, as amostras com CAP e AB apresentaram-se dúcteis e com menor velocidade de propagação das microtrincas.

Background: Nursing is an interpersonal process that requires a deeper emotive-caring and communion-encounter with a higher degree of emotional synchrony. However, the social, cultural, ethical, economic, legal, and technological demands make it intangible and indefinable.Purpose: To identify and delineate the antecedents, defining attributes, and outcomes of emotional synchrony using both empirical and theoretical literature.Methods: This concept analysis used the Norris’ method of concept clarification. Electronic databases such as OVID, Web of Science, CINHAL, PsychInfo, SocIndex, PubMed, and ProQuest were used to search the keyword ‘emotional synchrony.’ There were fifty-two sources included in the inductive thematic analysis to identify, analyze, recognize, and report the themes generated from the corpus. The discussion is grounded in light of the Theory of Nursing as Caring to elucidate its utility within the parlance of nursing as caring.Results: The Model of Patterning Emotional Synchrony offers a new perspective toward a meaningful synchronous experience in the communion of beings that illuminates a soul-felt connectedness through the encounter, presence, and bond. The emotional synchrony’ is a phenomenon of caring integration where an intricate dance through a triadic-synchronistic rhythm of fusion, attunement, and effervescence contribute to the personhood, growth in reflection, and capacity to care. Also, as the emotional synchrony becomes an outward expression of caring, and as a manifestation of healing-caring-moment, the person embodies caring as a mode of being and views all persons as caring.Conclusion: The model explicates that it is the emotional synchrony where the person develops a soul-felt connection with others. It is with emotional synchrony that refuels the synergy and transcendence towards a communion of beings to embody Amo Ergo Sum—I love. Therefore, I am.
Interprofessional Education (IPE) in Developing Countries: Challenges and Lesson Learnt from its Implementation in the United Kingdom: A Systematic Review
Authors: Sulistyowati Endah , Walker Louise
Published: December 2019

Background: Evidence of effectiveness of the Interprofessional Education (IPE) in improving collaboration practice, patient and family satisfaction, and patient outcomes had been widely published. Most of developed countries, including United Kingdom, have implemented IPE in their healthcare curriculum, whereas some developing countries are starting the IPE initiative program.Purpose: This study aims to examine the challenges in implementing IPE.Methods: Primary studies to be included in this systematic review were searched fromelectronic databases such as MEDLINE (OVID) 1996, CINAHL, and ERIC (EBSCO). Hand searching through journal of inter-professional care was also conducted. The included studies were critically appraised using JBI QARI appraisal tool. The findings of the included studies were extracted using JBI finding extraction form and appraised based on the JBI level of credibility. The analysis of the study was presented in narrative form.Results: This review produced five qualitative studies using focus groups and interview methods. A total of 5 out of 88 papers met the inclusion criteria included in this systematic review. Three synthesis findings of the challenges in implementing IPE and possible solutions were identified in the literature: inter-professional relationship, IPE curriculum, and administration and resources.Conclusions: The evidence of implementing IPE in developing countries is limited. However, the challenges in implementing IPE in developing countries remain similar with those faced by developed countries. This can be guidance for developing countries to plan, initiate and implement IPE. Future studies about implementation of IPE in developing countries are highly recommended.

Published: December 2019

Background: Diabetes Mellitus (DM) is a chronic and non-communicable disease that has serious impacts. Previous studies have focused on a single intervention in the management of DM. Therefore, EMAS (education, nutrition management, physical activities, and stress management) interventions are proposed to convey the pillars of diabetes mellitus as endorsed by the Indonesian Ministry of Health.Purpose: This study aimed to analyze the effects of EMAS interventions on the knowledge, attitudes, skills, and glucose control in patients with type-2 DM.Methods: This study used a pretest-posttest quasi-experimental design without control groups. The samples were 86 diabetic patients recruited using a purposive sampling technique. The EMAS interventions were conducted for six months and eight sessions (October 2018 to March 2019). The EuroQoLfive-dimensional (EQ-5D) questionnaire was used to collect the data, and the paired t-test was used for data analysis.  Results: The results showed that there were significant differences in the knowledge, attitudes, skills (p=0.001), and glucose control (p=0.04) of type 2 diabetes mellitus after the implementation of EMAS interventions. Conclusion: EMAS interventions significantly increased the knowledge, attitudes, and skills in patients with type 2 diabetes to behave healthier to control their blood sugar. Community nurses can use EMAS intervention for the management of DM among diabetic patients.

Background: The peripheral neuropathy is the cause of hospitalization for patients with diabetes mellitus (DM) and damages kidney function due to the circulatory system with high sugar levels. High sugar levels in DM patients with diabetic wounds can trigger glomerular damage resulting in the decrease of kidney function.Purpose: This study aims to analyze the relationship between the degree of diabetic wounds and kidney functions in patients with DM.Methods: A cross-sectional study was conducted on 723 DM patients who experienced diabetic wounds in a hospital in Mojokerto, East Java, Indonesia. A purposive sampling technique was used to recruit the samples. The data of this study were medical records of diabetic patients. A simple linear regression test was employed to analyze the data.Results: The result showed that the degree of diabetic wound was significantly related to kidney function damage (p=0.000). The relationship between the degree of diabetic wounds and the decline in kidney function was shown by an R-squared value of 0.768, meaning that the degree of diabetic wound affected the decline of kidney function by 76.8%, while the 23.2% was affected by other factors.Conclusion:The degree of diabetic injury affects the decline of kidney function in DM patients by 76.8%. Nurses should do health promotion about controlling blood sugar levels in DM patients with the prevention of four pillars of diabetes, including education, nutrition, physical activity, and stress.
Electrodynamics in Euclidean Space Time Geometries
Authors: Schliewe Jörn
Published: December 2019

In this article it is proven that Maxwell’s field equations are invariant for a real orthogonal Cartesian space time coordinate transformation if polarization and magnetization are assumed to be possible in empty space. Furthermore, it is shown that this approach allows wave propagation with finite field energy transport. To consider the presence of polarization and magnetization an alternative Poynting vector has been defined for which the divergence gives the correct change in field energy density.
Svaka majka doji svoje dite, samo ako ima mlika
Authors: Pleše Iva
Published: December 2019

Etnografski zapisi s kraja 19. i početka 20. stoljeća, nastali u suglasju s Osnovom za sabiranje i proučavanje građe o narodnom životu te objavljeni u Zborniku za narodni život i običaje južnih Slavena, nude mogućnost razgradnje popularnog narativa o zlatnom dobu dojenja u prošlosti, prije razvoja industrije dojenačkih mliječnih pripravaka, te podupiru razumijevanje dojenja, suprotno diskursima o njegovoj prirodnosti, kao kulturno i društveno utemeljene prakse. Na temelju čitanja spomenutih etnografskih zapisa ovaj se tekst bavi odstupanjima od norme postavljene u Osnovi, a prihvaćene i u stručnoj literaturi, po kojoj (u seoskoj sredini na prijelazu stoljeća) (svaka) majka doji svoje dijete. Tekst se tako bavi problemima vezanim za dojenje i laktaciju s kojima su se susretale majke novorođenčadi i dojenčadi te tzv. umjetnom prehranom najmanje djece, a upućuje i na prakse davanja djeteta na dojenje, kombiniranja ženskog rada i brige o malome djetetu i sl. što sve govori i o uvjetima u kojima se dojenje odvijalo a koji su bili, za žene i djecu, izrazito nepovoljni. Tekst također upućuje na potencijal povezivanja uvida koje nudi Zbornik za narodni život i običaje sa suvremenim diskursima o dojenju.

Published: December 2019

Ljudsko tijelo je uronjeno u mrežu kompleksnih normi, očekivanja, pravila i izvedbi. Ono je svojevrstan “medij kulture” (Bordo 2003: 165) i sjecište individualnog i socijalnog (Gimlin 2002). Tijelo je i sredstvo osobnog izražavanja u svakodnevnom životu. Rod je jedna od krucijalnih kategorija za razumijevanje tijela. Analize tijela iz rodne perspektive pokazuju kako se kreira i prezentira orodnjeno (feminino ili maskulino) tijelo. Postoji diskrepancija između drugovalnih i trećevalnih feminističkih interpretacija različitih praksi uljepšavanja i proizvodnje normativnog femininog tijela. U radu se kategorija roda isprepliće s kategorijom dobi pri čemu su u fokusu analize iskustva i interpretacija vlastitih tijela iz pozicije starijih žena. Intervjui su provedeni sa starijim ženama, rezidenticama četiri doma za starije osobe u Zagrebu i Splitu. U fokusu analize je njihova percepcija vlastitog tijela i fizičkog izgleda, svakodnevne prakse održavanja funkcionalnosti tijela, svakodnevne prakse uljepšavanja te interpretacije recentnih dominantnih standarda ljepote.

Infectious diseases are a major threat to humans, and finding sources of infection is therefore an important task. We designed a website to help teachers communicate the relevant principles of infectious diseases, deepen students' understanding of disease transmission, and equip students with the ability to trace the origin of infections caused by microorganisms. The website enables multi-person online use, with real-time recording of the exchange process and real-time viewing of infection results. Additionally, the website is able to preserve data permanently by setting multiple infection sources, providing a better simulation of real-world scenarios. Test use of the website by 120 students demonstrated that it has no significant bugs.

This paper investigates the effect of valve deactivation (VDA) on idling performance in port fuel injection (PFI) engine. The test was conducted on 1.6L, 4-cylinder engine with PFI configuration. One of the two intake valves in each cylinder was deactivated (zero lift on deactivated port) and fuel injector was modified to only provide fuel spray on the active intake port. In-cylinder pressure was recorded by the combustion analyzer in order to measure and analyze the combustion characteristics. From the test, there are up to 6% of fuel consumption improvements across all the test conditions. Better combustion stability is achieved at very low idling speed (throttle position, TP = 2%) as a lower coefficient of variation of engine speed (COVrpm) and coefficient of variation indicated mean effective pressure (COVimep) were recorded. Increased intake velocity and swirl flow in the VDA strategy creates more turbulence intensity causing higher heat release rate and faster combustion. However, there is no significant difference in the pumping work during the intake cycle but there is extra pumping work recorded towards the end of expansion stroke due to the very early end of combustion. Therefore, valve deactivation strategy provides limited positive improvement to the idling performance in PFI engine.
