Authors: Adugna Dagnew Getnet , Oumar Mohammed , Adugna Asmamaw
Published: April 2021

Background: Premature birth remains a serious public health problem in developing countries including Ethiopia. Ethiopia is one of the country with highest preterm birth rate in Africa. However, there is limited evidences on the prevalence and associated factors of premature birth. Therefore, this study was aimed to assess the prevalence and associated factors of premature birth among newborns delivered in Amhara region referral hospitals, Northern Ethiopia.Methods: A hospital-based cross-sectional study was undertaken from February 23rd to April 23rd, 2020, in the Amhara region. A total of 482 mother-newborn pairs were included in this study. The data were collected by interviewing the mothers and reviewing their charts using a structured and pretested questionnaire. The outcome variable was preterm birth. Data were entered using Epi-data version 4.6 and analyzed using STATA software (version 14). Bivariable and multivariable logistic regression models were done for the factors associated with premature birth. Results: In this study, the prevalence of premature birth was 11.41%(95% CI: 8.9, 14.6%). In multivariable logistig regression model; maternal age < 20 years (Adjusted odds ratio (AOR) = 7.8: 95% CI 2.3 – 26 ), preeclampsia (AOR = 5: 95% CI 2.3 – 11 ), premature rupture of membrane (AOR=3.9: 95%CI 1.6- 9.0), chronic medical illness (AOR=4.6:95% CI2.1-10), and history of stillbirth (AOR = 2.7: 95% CI 1.1-7.3) were significantly associated with preterm birth.Conclusion: The finding of this study showed that the burden of premature birth is a public health concern among newborns delivered in Amhara region referral hospitals. Maternal age less than 20 years, preeclampsia, premature rupture of membrane, chronic medical illness, and history of stillbirth were factors associated with preterm birth. Therefore, efforts have to be made to reduce the burden of prematurity, and for early detection and management of preeclampsia. Premature rupture of membrane, and chronic medical illness. Obstetric care providers should give due attention to women with an age of less than 20 years and a history of stillbirth.

Background: Despite substantial improvement in chronic total occlusions (CTO) revascularization technique, the long-term clinical outcomes in diabetic patients with revascularized CTO remain controversial. Our study aimed to investigate the five-year cardiovascular survival for patients with or without type 2 diabetes mellitus (DM) who underwent successful percutaneous coronary intervention (PCI) for CTO. Methods: Data of the current analysis derived from a large single-center, prospective and observational cohort study, including 10,724 patients who underwent PCI in 2013 at Fuwai Hospital. Baseline, angiographic and follow-up data were collected. The primary endpoint was major adverse cardiac and cerebrovascular events (MACCE), which consisted of death, recurrent myocardial infarction (MI), stroke and target vessel revascularization (TVR). The secondary endpoint was all-cause mortality. Cox regression analysis and propensity-score matching was performed to balance the baseline confounders. Results: A total of 719 consecutive patients with ≥ 1 successful CTO-PCI were stratified into diabetic (n=316, 43.9%) and non-diabetic (n=403, 56.1%) group. During a median follow-up of 5 years, the risk of MACCE (adjusted hazard ratio [HR] 1.47, 95% confidence interval [CI] 1.08-2.00, P = 0.013) was significantly higher in the diabetic group than in the non-diabetic group, whereas the adjusted risk of all-cause mortality (HR 2.37, 95% CI 0.94-5.98, P = 0.068) was similar. In the propensity score matched population, there were no significant differences in the risk of MACCE (HR 1.27, 95% CI 0.92-1.75, P = 0.155) and all-cause mortality (HR 2.56, 95% CI 0.91-7.24, P = 0.076) between groups. Subgroup analysis revealed a consistent effect on five-year MACCE across various subgroups.Conclusions: In patients who received successful CTO-PCI, non-diabetic patients were related to better long-term survival benefit in terms of MACCE. Further randomized studies are warranted to confirm these findings.
Superpixel Image Segmentation of the Tumoral Microenvironment in Colorectal Cancer: Frontiers Beyond the Microscope
Authors: Hacking Sean , Wu Dongling , Alexis Claudine , Nasim Mansoor
Published: April 2021

Colorectal cancer (CRC) is the most common malignancy of the gastrointestinal (GI) tract and accounts for 9% of all cancers. The stroma and the tumoral microenvironment represent brave new frontiers for patients with colorectal cancer. Here we demonstrate novel superpixel image segmentation (SIS) techniques for whole slide images (WSI) to unravel this biology. Findings of significance include the association of low proportionated stromal area (PSA), high immature stromal percentage (ISP) and high myxoid stroma ratio (MSR) with worse prognostic outcomes in our CRC patients. Overall, stromal markers outperformed all others at predicting clinical outcomes. In particular, MSR may be able to prognosticate patients independent of tumor stage and may be the most optimal way to effectively prognosticate CRC patients which circumvents the need for more extensive deep learning (DL) based computational profiling. Approaches demonstrated here can be performed by a trained pathologist and very easily recorded during synoptic cancer reporting with appropriate quality assurance. Future well-designed, robust clinical trials will have the ultimate say in determining whether digital image analysis and superpixel image segmentation can better tailor the need for adjuvant therapy in patients with colorectal cancer.

Published: April 2021

Introduction: In late 2019, a novel coronavirus was detected in China. Supported by its respiratory transmissibility, even by people infected without symptomatic disease, this coronavirus soon began to rapidly spread worldwide. Background: Many countries have implemented different infection control and containment strategies due to ongoing community transmission. In this context, contact tracing as well as adequate testing and consequent quarantining of high-risk contacts play leading roles in containing the virus by interrupting infection chains. This approach is especially important in the hospital setting where contacts often cannot be avoided and physical distance is usually not possible. Furthermore, health care workers (HCWs) usually have contact with a variety of vulnerable people, making it essential to identify infections among hospital employees as soon as possible to interrupt the rapid spread of SARS-CoV-2 in the facility. Several electronic tools for contact tracing, such as specific software or mobile phone apps, are available for the public health sector. In contrast, contact tracing in hospitals often has to be carried out without helpful electronic tools, and an enormous amount of human resources is typically required. Aim: For rapid contact tracing and effective infection control and management measures for HCWs in hospitals, adapted technical solutions are needed.Methods: In this study, we report the development of our containment strategy to a web-based contact tracing and rapid point-of-care-testing workflow.Results/Conclusion: Our workflow yielded efficient control of the rapidly evolving situation during the SARS-CoV-2 pandemic from May 2020 until January 2021 at a German University Hospital.

Background: Bladder cancer (BCa) is a challenge carcinoma that occurs on the bladder mucosa, which is the most common malignant neoplasm of the urinary system. Great efforts have been made to elucidate its pathogenesis. However, the molecular mechanisms involved in BCa remain unclear. Therefore, there is an urgent need to identify effective biomarkers to accurately predict the progression and prognosis of BCa.Material and methods: To investigate potential prognostic biomarkers of BCa, we download the GSE23732 expression profile from Gene Expression Omnibus (GEO) database. The GEO2R analysis tool was performed to identify the DEGs between BCa and normal bladder mucosae tissue. Gene Ontology (GO) functional annotation analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed for the screened DEGs by the Database for Annotation, Visualization, and Integrated Discovery (DAVID) online tool. We employed the Search Tool for the Retrieval of Interacting Genes (STRING) database to construct the protein-protein interaction (PPI) network of DEGs. Subsequently, the PPI network’s information was visualized by Cytoscape software. The Gene Expression Profiling Interactive Analysis (GEPIA) resource was used to describe the OS and DFS outcomes in bladder cancer patients based on the hub genes expression levels.Results: A total of 396 DEGs comprising 344 upregulated genes and 52 downregulated genes were screened. The results of the GO analysis showed that DEG was mainly enriched in proteinaceous extracellular matrix, extracellular matrix, heparin binding and extracellular matrix organization. In addition, KEGG pathway analysis showed that DEGs were mainly enriched in PI3K-Akt signaling pathway, Focal adhesion, MAPK signaling pathway. A PPI network was constructed using the 396 DEGs, 10 hub genes were selected and 4 of them including MYLK, CNN1, TAGLN and LMOD1 were associated with overall survival and disease-free survival.Conclusion: MYLK, CNN1, TAGLN and LMOD1 may represent promising prognostic biomarkers and potential therapeutic option for BCa.

Knowledge of short-term physiological adaption of wheat to soil water deficit is well understood, but little is known about seed ethylene priming effect on long-term drought stress memory of dryland winter wheat. The 42 leading and new cultivars released between 1992 to 2017 were subjected to drought (45% Field water-holding capacity), and well-watered (75% Field water-holding capacity) conditions aim to screen cultivars with contrasting drought resistance and grain yield. Seeds primed with ethylene were subjected to both PEG-8000 and pure water to uncover ethylene-induced stress memory at both physiological and organ levels. Results showed that the soil water deficit (45%FC) that occurred at the tillering stage resulted in 3.2% to 67.4% yield loss for 42 cultivars, which was determined mainly by the decrease in the fertile spike. Seed ethylene priming maintained leaf water by reducing root volume and dry weight, which played a crucial role in drought avoidance. Seed ethylene priming decreased malondialdehyde content by regulating auxin and abscisic acid signaling, reactive oxygen species scavenging capability, and osmotic regulation, which plays a crucial role in drought tolerance. Seed ethylene priming improved drought tolerance of the wheat through metabolic modification of carbon metabolism, glutathione metabolism, and phenylpropanoid biosynthesis . The seed ethylene priming induced long-term stress memory that improved tillering capacity and reduced wheat spikelets abortion, which provided extra 0.3 t ha -1 of grain yield. These results suggested that seed ethylene priming allowed the recall of long-lasting stress defensive memory, increasing grain yield by both drought avoidance and drought tolerance.

Authors: A Rajagopal , V Nirmala , J Andrew , M Arun
Published: April 2021

The effect of the COVID-19 pandemic on mental health is substantial. The World Health Organization has called for action to avert an impending mental health crisis. To respond to this call, this paper contributes a novel application of Deep Learning in Natural Language Generation (NLG) to seed healthy thoughts for mental health therapy. For the 1st time in literature, a transfer learning capable large neural network with more than 100 million parameters for a NLG based mental health therapy application is proposed & demonstrated. This AI is designed to address scalable impact for millions of families with a timely health intervention in a privacy-safe approach. To the best of our knowledge, this is the first research paper to apply GPT2 (Generative Pretrained Transformer) for Cognitive Behavior therapy (CBT). Further, the paper demonstrates the proposed neural network architecture with a lab prototype implementation with reproducible results. This paper demonstrates this AI’s ability to generate conditional synthetic human-like text intended to seed a healthy mental outlook. This is accomplished by fine tuning a pre-trained GPT2 language model. The source code and video demonstration is contributed at https://sites.google.com/view/ai-in-mental-health.Also, for the 1st time in literature, a novel idea of NLU (Natural Language Understanding) activated NLG therapy is demonstrated with reproducible results using a BERT based classifier to activate the GPT2 based therapy. Performance of GPT2 models of three different sizes (124, 355, 774 million parameters) was the same for a very small dataset, thus a small GPT2 model is suggested for on-device AI inference. This AI is a step forward in responding to WHO’s call for action to avert the crisis. Towards addressing all the three dimensions of the monumental challenge, the paper designed a novel AI architecture by taking advantage of both BERT & GPT2. It also demonstrated the feasibility of Transformers-based AI for developing a mental health therapy solution. Further, this paper contributed an open-source AI prototype to support research communities to transform global mental wellness.
Relativity and View Effects
Authors: Fischli Bernard
Published: April 2021

Relativity has been based on the implicit assumption that electromagnetism would exclusively describe interactions. Relativistic view effects are included as well, and they act with no force and no energy exchanges. The Ehrenfest paradox is solved. View effects specific to each point of view are the solution. The calculation of the deflection of light by the sun explains in detail why the deflection angle must be almost double the value obtained with Newton’s laws. The compatibility of General Relativity with the new interpretation is discussed. View effects cannot impact total energy. An object has no speed limit due to relativity but can be limited due to other causes. Inertial behavior is examined. Inertial masses are redundant, but this does not introduce gravitation to General Relativity.

In wireless networks, propagation models are used to assess the received power signal and estimate the propagation channel. These models depend on the pathloss exponent (PLE) which is one of the main parameters to characterize the propagation environment. Indeed, in the wireless channel, the path loss exponent has a strong impact on the quality of the links and must therefore be estimated with precision for an efficient design and operation of the wireless network. This paper addresses the issue of path loss exponents estimation for mobile networks in four outdoor environments. This study is based on measurements carried out in four outdoor environments at the frequency of 2600 MHz within a bandwidth of 70 MHz. It evaluates the path loss exponent, and the impact of obstacles present in the environments. The parameters of the propagation model determined from the measurements show that the average power of the received signal decreases logarithmically with the distance. We obtained path loss exponents values of 4.8, 3.53, 3.6 and 3.99 for the site 1, site 2, site 3 and site 4, respectively. Clearly the density of the obstacles has an impact on the path loss exponents and our study shows that the received signal decrease faster as the transmitter and receiver separation in the dense environments.

Background: Bisphenol A is characterized as an endocrine disruptor as it interferes with the synthesis of hormones and metabolism resulting in abnormality in the homeostatis of exposed persons. It is used in the production of polycarbonate and epoxy resins which are utilized in the preparation of almost all plastic packaging materials like plastic bottles, cans, food containers, and coating on food containers. Objective: To detect leaching of Bisphenol A in 15 samples of Bottled water and Beverages using High Performance Liquid Chromatography. Methods: Liquid-liquid extraction technique was used for analytical detection of BPA from bottled drinking water and beverages. Results: BPA contamination in Bottled drinking water was calculated through mean concentration for a time period of 30 days as (0.38 ng/ml - 0 day), 8.86 ng/ml (5th day), 17.85 ng/ml (10th day), 30.35 ng/ml (20th day) and 44.48 ng/ml (30th day)). The mean concentration of BPA was observed to be 0.25 to 2.25 ng/ml. Also, the mean concentration of BPA at different temperatures was observed to be 5.96 ng/ml (at 40C), 5.62 ng/ml (at 200C) and 8.80 ng/ml (at 550C). The above results revealed presence of high concentration of BPA in all the samples of bottled drinking water and beverages. Conclusion: The results obtained in the above study depicted considerable amount of BPA leaching from bottled containers into drinking water and beverages. Prolong usage of bottled water and beverages should be avoided to reduce the risk of human exposure to BPA through leaching. Also, it was found that high temperatures resulted in increased BPA leaching.

How aspiration and expectation shortfalls drive strategic investments
Authors: Mammen Jan
Published: April 2021

Performance feedback is an important concept to explain managerial risk taking. This paper aims to distinguish between two forms of performance feedback: A performance shortfall can be positively or negatively associated with risk inclination. The first effect arises for a shortfall from aspirations, while the second effect occurs if there is a shortfall from expectations. The hypotheses are tested on a sample of S&P 1500 firms over a period of 19 years (1992–2010) using a fixed effects regression model. The empirical results suggest that missing aspirations increases the likelihood of risk taking in the form of higher strategic investments. Missing expectations in contrast diminishes managerial power and discretion to engage in risk taking and thus lowers strategic investments. The results further support the idea that both effects reinforce each other, suggesting that shortfalls from expectations and aspirations have an interactive effect. By distinguishing between these two sides of performance feedback, this study provides an improved understanding on managerial risk taking. Additionally, this paper highlights how motivation and power interact when analyzing managerial risk taking.

Women in rural Madura prefer to live alone as a widow after being left by husbands (divorced/deceased). This phenomenon is better known as a single mother. The single mother women perform dual roles in the family, namely public roles and domestic roles. This research focuses on the causes of women who prefer to be single mothers as well as their strategies in maintaining resilience in the family. The case study approach and qualitative methods are used to understand the phenomenon. The data show that several factors influence women in Ponteh village to live longer as single mothers than men after getting divorced. Firstly, wanting to raise their children, secondly, for women, divorce is a traumatic event, third, understanding of Islamic thought, fourth, social prestige. The resilience of single mothers is indicated by their multiple roles as women. Women are more active in productive activities as well as reproductive or domestic activities. The contribution of this article is to explain more about the single mother phenomenon in rural Madura.

Published: April 2021

Since the early 20th century, villages in the city of Yogyakarta has started to become villages of tourism following the government promoting tourism in the region. Originally carrying local and cultural identities, those villages appear to be touristic, accommodating the needs of the visitors. This work attempts to explore how this social phenomenon happening to two urban villages within the city namely Kampung Kauman and Kampung Prawirotaman. It focuses on explaining how the villagers actively play their roles in the neighborhood in social and cultural processes within the new environment and physical space.  The appropriate data found in the field is analyzed accordingly to the research questions by employing a qualitative approach.  The work suggests that cultural identity has changed in these two urban villages as a result of the influence of external values promoting the redefinition and redesign of public and social space. Besides, it also finds that delegitimization of the identity of Kampung and communality dislocation has occurred due to tourism purposes. The new formulation of the Kampung does not only reflect the emergence of new ideology and tradition but also stimulate resistance, conflict, and negotiation. This study recommends the importance of mentoring programs from the strategic stakeholders for better space and cultural transformation leading to the prevention of the damage of local wisdom basis within urban communities.
Representasi Identitas Muslimah Modern “Jilbab Traveler” dalam Novel Karya Asma Nadia
Authors: Putri Rani Dwi
Published: April 2021

Following the fall of the New Order era, which encouraged media development and openness, Islam was positioned as a dominant identity in public spaces. Asma Nadia is one of the actors who is become one part of those phenomena. Her works in novels, films and soap operas have succeeded in combining modern elements with Islamic symbols and values. The theme of Jilbab traveler is one example. Applying text analysis focusing on three works of Asma Nadia’s novels, namely The Jilbab Traveler; Assalamualaikum Beijing; Jilbab Traveler: Love Sparks in Korea, this article reveals that Asma Nadia illustrates "jilbab traveler" as both agile and pious. The ambition to travel around the world accompanied by its inherent attributes represents the figure of “jilbab traveler” as an agile woman, while hijab (veil) presents an image of a pious woman. On the other side, the wearing of the veil becomes a distinction and provides such negotiation space and illustrates the hegemonic masculinity of patriarchal culture.

Published: April 2021

This article presents Russia’s main achievements of over the past 65 years in the development of an advanced scientific and technical groundwork for the introduction of hydrogen as a fuel in various energy systems. On the basis of the obtained world-class results, the authors argue for the necessity of creating a Center for Hydrogen Innovative Development (CVIR) with the decisive participation of enterprises with real experience in obtaining liquid hydrogen (H2l) with the possibility of its long-term storage.
A concept has been formulated for the development of breakthrough technological solutions for the widespread use of hydrogen as an efficient and environmentally friendly (without the formation of carbon oxides) fuel in various power systems within the framework of the CVIR. In particular, the strategic direction of the CVIR project was developed in order to create a developed infrastructure for the reliable provision of vehicles with the required amount of fuel in a limited period of time. This can be achieved by applying the method of cryogenic filling of transport cylinders, taking into account the real properties of hydrogen in the ultra-high pressure region (70 MPa and above).
The results have revealed possibilities for further building up the advanced scientific and technical groundwork for the broad promotion of hydrogen in the energy complex of Russia, which is presented in the CVIR project. In addition, the authors have compared the developed technologies with foreign analogues.

Published: April 2021

This article deals with a problem that describes the propagation of surface waves in a layer of an inhomogeneous fluid. The authors present a mathematical model that describes wave motions on the surface of an ideal exponentially stratified fluid. In the equations and boundary conditions, the transition to dimensionless variables and quantities has been completed. Next, a linear version of the problem follows, the solution of which is in the form of progressive waves of a steady-state form with unknown amplitude coefficients. This type of solution is substituted into the equations and boundary conditions of the linear problem, which makes it possible to reduce the determination of unknown quantities to the problem of solving a system of ordinary differential equations. Solving the system has allowed identifying two areas of physical parameters with different nature of wave motion. Expressions are obtained for the unknown components of the fluid velocity, pressure, free surface shape, and wave frequency.
This article contains the analysis of the influence of various parameters of the problem on the wave motion: graphs of the dependence of the phase velocity of the wave on the stratification parameter are constructed for different layer depths and wavelengths. For a better understanding of the nature of wave motion, the expressions for the trajectories of liquid particles are determined. This has required writing the equations of motion of particles using the obtained expressions for the components of the velocity vector; these equations are solved with the method of asymptotic approximations. A graphical analysis of the effect of the stratification parameter value on the particle trajectory shape is carried out. The results have revealed that an increase in stratification leads to a compression of the trajectory in the vertical direction.

Establishing the characteristics of the self-assembly of micron and sub-micron particles when colloidal solution droplets evaporate from solid surfaces is an urgent problem. This is explained by the possibility of using these structures obtained by droplet technologies to create and optimize the production of direct and indirect liquid cooling devices, electronic and sensor working boards, current-conducting coatings, optical crystals, and chemo sensors. The method used in this study for processing of metals and alloys by laser radiation is prospective for controlling the processes at the liquid/gas/solid interface.
This article aims to analyze the effect of laser processing of the widely used in the industry aluminum-magnesium alloy on the formation of a layer of particles during the droplet evaporation of colloidal solutions. The samples’ surfaces were processed by two methods: polished by tumbling and nanosecond laser pulses. The geometric parameters of the droplets of colloidal solutions evaporating from the samples’ surfaces were determined by the shadow method. To process the obtained shadow images, the Young — Laplace method was used. Using a scanning electron microscope, the authors have received the images of the particles’ layers formed due to the droplet evaporation of colloidal solutions.
The experimental studies reveal the effect of texture formed on aluminum-magnesium alloy sample on the morphology of the layer of polystyrene nanoparticles during the droplet evaporation of colloidal solutions. Due to the self-assembly of particles, solid ring-like sediments are formed, which are elongated under the action of the capillary force parallel to the motion vector of the laser beam (when creating the texture). When the solvent evaporated from the solution droplet on the textured surface, in addition to the rings, a homogeneous layer of polystyrene particles was formed. This refers to the droplet evaporation of the solution.
The results show that with an increase in the concentration of particles in the solution, the sizes of radial cracks on the rings formed due to particle deposition increase. There were no cracks on the rings at a relatively low volume concentration of particles.
O USO DE INFOGRÁFICOS PARA A DISSEMINAÇÃO DE INFORMAÇÕES SOCIOECONÔMICAS: O CASO DE UMA INSTITUIÇÃO PÚBLICA DE PESQUISA
Authors: Gabriela Santos
Published: April 2021

O artigo trata do uso de infográficos na disseminação de informações socioeconômicas, considerando, principalmente, essa abordagem sob a perspectiva do design. O tema surgiu da constatação da falta de conteúdos teóricos sobre infografia relativos a esse campo e da verificação do uso de infográficos por instituições da área. Inicialmente, é feita uma revisão bibliográfica sobre infografia e questões referentes a informações socioeconômicas e, após o estudo, se tem um exemplo. Com o caso citado, é possível visualizar a prática – explicações, sugestões e resultados obtidos –, porém o fator mais importante evidencia-se com a explanação da metodologia utilizada, servindo de sugestão para a área e de base para estudos futuros. Tudo isso também enfatiza as potencialidades que a infografia proporciona, sobretudo para a área foco deste trabalho.

O presente trabalho teve como objetivo apresentar as mudanças que o estilo andrógino sofreu ao longo da história da moda e que influenciaram diretamente a ressignificação da indumentária de homens e mulheres. Dessa forma, o texto está dividido em três momentos. O primeiro define o conceito de androginia discorrendo sobre suas características e aplicação no universo da moda. O segundo traz a evolução histórica da moda andrógina através dos tempos por meio de estilistas, designers e marcas, e o terceiro momento discute a expressão do vestuário com base na identidade de gênero ao apresentar um experimento realizado em uma loja de departamento que analisa uma coleção sem gênero. Como resultado desta pesquisa, entende-se que a moda sem gênero foi construída no decorrer da história paralelamente com as transformações sociais.

Para o designer, a capacidade de trabalhar em equipes de modo colaborativo apresenta-se como alternativa para a oferta de soluções viáveis, num cenário em que a atuação individual é cada vez mais difícil, justificando a necessidade de desenvolver a colaboração como competência durante o ensino superior. O tema colaboração é amplamente pesquisado em todo o mundo, contudo a literatura científica não é suficientemente clara sobre tal conceito, pois apresenta diversos termos com significados semelhantes. Além disso, apesar da vasta literatura existente sobre o assunto, não é possível identificar uma descrição de como estimular essa competência de maneira estruturada. Diante de tal problemática, o objetivo deste artigo é conceituar a colaboração e identificar os componentes dessa competência que possam ser estimulados na educação em design. A revisão bibliográfica, que foi realizada em etapa sistemática e assistemática, bem como a análise exaustiva dos dados obtidos, culminou na proposição de um conceito de colaboração fundamentado na literatura, amplamente válido e aplicável não somente ao ensino de design, como também a outros contextos. O estudo resultou ainda na identificação de oito componentes da colaboração que podem ser fomentados em sala de aula com o objetivo de estimular a colaboração entre os estudantes.

Forest and land fire is mentioned as a main problem of peatlands occurring every year and has provided huge losses for all parties. The research aimed how to empower indigenous farmers with fish farming on South Sumatra peatlands. This research was conducted on peatlands in Ogan Komering Ilir (OKI) District. The sampling method was using cluster technique, questionnaire and through Focus Discussion Group (FDG). All collected data were analyzed with the SPSS version 21 program and the comparisons or analyzes the relationship between the variables were also analyzed. The research results concluded that the prospect of fish farming on peatlands is very prospecful. Empowering indigenous farmers can be done through local fish farming (e.g. fishes of gabus; tebakang; sepat siam; betok; gurami and toman), and introduced fish farming (i.e. fishes of patin siam; catfish, and nila). Fish farming technology for empowering farmers can be focused on drainage and irrigation systems to maintain groundwater levels; and applying soil ameliorant (e.g. dolomite for fish ponds, lime, manure, urea and NPK fertilizer).
