Published: March 2021

Psoriasis is an immune-mediated, chronic inflammatory disease, which mainly affects the skin, although it has systemic pathological effects. Comorbidities of psoriasis include ocular disorders, which are often nonspecific or mildly symptomatic. The aim of this study was to show the importance of ocular-disease screening in psoriatic patients using the Ocular Manifestations in Psoriasis Screening (OcMaPS) questionnaire. Patients suffering from moderate-to-severe psoriasis referring at our outpatient-clinic were consecutively enrolled. Each patient was asked to complete a screening questionnaire (OcMaPS). Patients reporting ocular symptoms were referred for an ophthalmological examination. A total of 372 patients were enrolled in the study. Ocular symptoms were detected in 39 patients (10.5%), and 37 patients were referred to ophthalmological examination which confirmed the presence of ocular manifestation in 30 patients. There were three cases (10%) of uveitis, 14 (46.6%) of dry eye and 13 (43.3%) of cataract, in progress or already treated with surgery. In the remaining seven patients, no ocular manifestations were found. Ocular manifestations in psoriatic patients are not rare. It is important to be aware of ocular symptoms in psoriatic patients, screening patients (with a consultation or OcMaPS questionnaire), which leads to earlier diagnosis and treatment.

Published: March 2021

Several kinds of inotropes have been used in critically ill patients to improve hemodynamics and renal dysfunction after cardiac surgery; however, the treatment strategies for reducing mortality and increasing renal protection in patients who underwent cardiac surgery remain controversial. Therefore, we performed a comprehensive network meta-analysis to overcome the lack of head-to-head comparisons. A systematic database was searched up to 31 December 2020, for randomized controlled trials that compared different inotropes on mortality outcomes and renal protective effects after cardiac surgery. A total of 29 trials were included and a frequentist network meta-analysis was performed. Inconsistency analyses, publication bias, and subgroup analyses were also conducted. Compared with placebo, use of levosimendan significantly decreased the risks of mortality (odds ratio (OR): 0.74; 95% confidence interval (CI): 0.56–0.97) and risk of acute renal injury (OR: 0.61; 95% CI: 0.45–0.82), especially in low systolic function patients. Use of levosimendan also ranked the best treatment based on the P-score (90.1%), followed by placebo (64.5%), milrinone (49.6%), dopamine (49.5%), dobutamine (29.1%), and fenoldopam (17.0%). Taking all the available data into consideration, levosimendan was a safe renal-protective choice for the treatment of patients undergoing cardiac surgery, especially for those with low systolic function.
Electroplating and Ablative Laser Structuring of Elastomer Composites for Stretchable Multi-Layer and Multi-Material Electronic and Sensor Systems
Authors: Stier Simon P. , Böse Holger
Published: March 2021

In this work we present the concept of electroplated conductive elastomers and ablative multi-layer and multi-material laser-assisted manufacturing to enable a largely automated, computer-aided manufacturing process of stretchable electronics and sensors. Therefore, the layers (conductive and non-conductive elastomers as well as metal layers for contacting) are first coated over the entire surface (doctor blade coating and electroplating) and then selectively removed with a CO2 or a fiber laser. These steps are repeated several times to achieve a multi-layer-structured design. Is it not only possible to adjust and improve the work previously carried out manually, but also completely new concepts such as fine through-plating between the layers to enable much more compact structures become possible. In addition, metallized areas allow the direct soldering of electronic components and thus a direct connection between conventional and stretchable electronics. As an exemplary application, we have used the process for manufacturing a thin and surface solderable pressure sensor with a silicone foam dielectric and a stretchable circuit board.

Published: March 2021

Immunomodulation of the tumor microenvironment is emerging as an important area of research for the treatment of cancer patients. Several synthetic and natural agents are being investigated for their ability to enhance the immunogenic responses of immune cells present in the tumor microenvironment to impede tumor cell growth and dissemination. Among them, resveratrol, a stilbenoid found in red grapes and many other natural sources, has been studied extensively. Importantly, resveratrol has been shown to possess activity against various human diseases, including cancer. Mechanistically, resveratrol has been shown to regulate an array of signaling pathways and processes involving oxidative stress, inflammation, apoptosis, and several anticancer effects. Furthermore, recent research suggests that resveratrol can regulate various cellular signaling events including immune cell regulation, cytokines/chemokines secretion, and the expression of several other immune-related genes. In this review, we have summarized recent findings on resveratrol’s effects on immune regulatory cells and associated signaling in various cancer types. Numerous immunomodulatory effects of resveratrol suggest it may be useful in combination with other cancer therapies including immunotherapy for effective cancer management.

Published: March 2021

The demand for carbon dioxide (CO2) gas detection is increasing nowadays. However, its fast detection at room temperature (RT) is a major challenge. Graphene is found to be the most promising sensing material for RT detection, owing to its high surface area and electrical conductivity. In this work, we report a highly edge functionalized chemically synthesized reduced graphene oxide (rGO) thin films to achieve fast sensing response for CO2 gas at room temperature. The high amount of edge functional groups is prominent for the sorption of CO2 molecules. Initially, rGO is synthesized by reduction of GO using ascorbic acid (AA) as a reducing agent. Three different concentrations of rGO are prepared using three AA concentrations (25, 50, and 100 mg) to optimize the material properties such as functional groups and conductivity. Thin films of three different AA reduced rGO suspensions (AArGO25, AArGO50, AArGO100) are developed and later analyzed using standard FTIR, XRD, Raman, XPS, TEM, SEM, and four-point probe measurement techniques. We find that the highest edge functionality is achieved by the AArGO25 sample with a conductivity of ~1389 S/cm. The functionalized AArGO25 gas sensor shows recordable high sensing properties (response and recovery time) with good repeatability for CO2 at room temperature at 500 ppm and 50 ppm. Short response and recovery time of ~26 s and ~10 s, respectively, are achieved for 500 ppm CO2 gas with the sensitivity of ~50 Hz/µg. We believe that a highly functionalized AArGO CO2 gas sensor could be applicable for enhanced oil recovery, industrial and domestic safety applications.

Published: March 2021

Forecasting shoreline evolution for sandy coasts is important for sustainable coastal management, given the present-day increasing anthropogenic pressures and a changing future climate. Here, we evaluate eight different time-series forecasting methods for predicting future shorelines derived from historic satellite-derived shorelines. Analyzing more than 37,000 transects around the globe, we find that traditional forecast methods altogether with some of the evaluated probabilistic Machine Learning (ML) time-series forecast algorithms, outperform Ordinary Least Squares (OLS) predictions for the majority of the sites. When forecasting seven years ahead, we find that these algorithms generate better predictions than OLS for 54% of the transect sites, producing forecasts with, on average, 29% smaller Mean Squared Error (MSE). Importantly, this advantage is shown to exist over all considered forecast horizons, i.e., from 1 up to 11 years. Although the ML algorithms do not produce significantly better predictions than traditional time-series forecast methods, some proved to be significantly more efficient in terms of computation time. We further provide insight in how these ML algorithms can be improved so that they can be expected to outperform not only OLS regression, but also the traditional time-series forecast methods. These forecasting algorithms can be used by coastal engineers, managers, and scientists to generate future shoreline prediction at a global level and derive conclusions thereof.
A New Approach for Identification of Potential Rockfall Source Areas Controlled by Rock Mass Strength at a Regional Scale
Authors: Wang Xueliang , Liu Haiyang , Sun Juanjuan
Published: March 2021

The identification of rockfall source areas is a fundamental work for rockfall disaster prevention and mitigation. Based on the Culmann model, a pair of important indicators to estimate the state of slope stability is the relief and slope angles. Considering the limit of field survey and the increasing requirements for identification over a large area, a new approach using the relief–slope angle relationship to identify rockfall source areas controlled by rock mass strength at a regional scale is proposed in this paper. Using data from helicopter-based remote sensing imagery, a digital elevation model of 10 m resolution, and field work, historical rockfalls in the Wolong study area of Tibet where frequent rockfalls occur are identified. A clear inverse relationship between the relief and slope angles of historical rockfalls enables us to calculate the rock mass strength of the landscape scale by the Culmann model and the relief–slope angle relationship curve. Other parameters used in our proposed approach are calculated by ArcGIS and statistic tools. By applying our approach, the potential rockfall source areas in the study are identified and further zoned into three susceptibility classes that could be used as a reference for a regional rockfall susceptibility study. Using the space partition of historical rockfall inventory, our prediction result is validated. Most of the rockfall source areas (i.e., 71.92%) identified in the validation area are occupied by historical rockfalls, which proves the good prediction of our approach. The dominant uncertainty in this paper is derived from the process of calculating rock mass strength, defining the specific area for searching potential rockfall source areas, and the resolution of the digital elevation model.
A Study on the Millennials Usage Behavior of Social Network Services: Effects of Motivation, Density, and Centrality on Continuous Intention to Use
Authors: Park Gwijeong , Chen Fangxin , Cheng Le
Published: March 2021

Whether in terms of social media platforms, mobile pay apps or an increasing acceptance of RFID chips in humans, technology has transformed everyday life for consumers. Social networks have experienced enormous growth as online personal networking media. Social exchange theory (for motivation and social reward) and theories of collective action can be applied in order to understand how an individual’s behavior may exert effects on or receive influences from other users with regard to the continuance usage intention of social apps. First, this study aims to examine behavioral characteristics of the Millennials, and takes flow and social reward systematically so as to explore SNS users’ continuance based on SNS characteristics. Targeting Millennials SNS users, this study empirically examines users’ continuance intention at individual level and simulates users’ continuance behavior at group level, which are expected to be influential as a next generation of purchasing group, focusing on social network services (SNS) usage. Second, this study tries to suggest strategic implications by identifying key factors that dominate SNS users’ behavior in the process of experiencing SNS. For the empirical purpose, this study analyzes the relationship between SNS characteristics (motivation to use, density, and centrality) and usage behavior (flow, social reward, and continuous intention to use). As a result, each construct of motivation to use SNS, SNS density, and SNS centrality are positively linked with flow. Motivation to use SNS and SNS centrality are positively associated with social reward, however, SNS density does not have a significant effect on social reward. In addition, flow and social reward turn out to have positive linkage with continuous intention to use respectively. The findings of this study are expected to provide implications for researchers and operators in related fields to identify various factors that explain the SNS usages of the Millennials, especially the major factors that sustain SNS involvement and activities. This study can enrich both SNS continuance theory, and help SNS operators to manipulate resources effectively to attract and retain users.
How an Integration of Home Energy Management and Battery System Affects the Economic Benefits of Residential PV System Owners in Thailand
Authors: Srikranjanapert Methee , Junlakarn Siripha , Hoonchareon Naebboon
Published: March 2021

Although home energy management systems (HEMS) and batteries are part of the Thailand Smart Grid Master Plan, the financial feasibility and attractiveness of installing residential solar rooftop photovoltaic (PV) systems with integration of the HEMS and battery have never been investigated. This study develops three scenarios comprising of an installation of only solar PV system, solar PV system with the HEMS, and solar PV system with integration of the HEMS and battery under the current net billing solar program for households and analyzes their financial feasibility and attractiveness by using economic measures. In addition, sensitivity analysis is performed to analyze the impacts of critical parameters on the feasibility of these three scenarios. Findings indicate that the installation of a solar rooftop system with the HEMS provides the highest customer economics. Although the implementation of HEMs leads to an increase in energy exports, benefits from bill savings of lower electricity consumption by using the HEM are relatively high compared to the loss from energy exports. Therefore, in the short term, the government should promote the integration of HEMS with a PV system; however, the installation of a PV system with HEMS and battery in the residential sector should be promoted when battery cost decreases.
Effects of Three Levels of Green Exercise, Physical and Social Environments, Personality Traits, Physical Activity, and Engagement with Nature on Emotions and Attention
Authors: Han Ke-Tsung
Published: March 2021

The current study examined the effects of the three levels of green exercise on people’s psychological health using a randomized trial with a pretest and posttest design and further explored which variables of the physical environment (thermal comfort, noise, and air pollution), social environment (the number of companions and crowdedness), personality traits, physical activity (intensity and frequency), and engagement with nature may help explain experiences during the three levels of green exercise using a cross-sectional approach. Field studies were conducted to test the study’s hypotheses. The participants were 95 students from a technology university in Taiwan. The experiment comprised a 15-min green exercise in a park. No significant differences were found in emotions and attention between the three levels of green exercise. However, a 15-min green exercise of any level significantly improved emotions and attention. Furthermore, fatigue was significantly and negatively associated with daily transportation-related physical activity, agreeableness, and engagement with nature. Moreover, the total mood disturbance was significantly and negatively associated with engagement with nature and daily transportation-related physical activity. The degree of engagement with nature played a pivotal role in green exercise. This study provided the evidence that quantified engagement with nature is beneficial for quantified psychological health for the first time.

Published: March 2021

Educational systems consider fostering creativity and cooperation as two essential aims to nurture future sustainable citizens. The cooperative learning approach proposes different pedagogical strategies for developing creativity in students. In this paper, we conceptualize collaborative creativity under the framework of coordination dynamics and, specifically, we base it on the formation of spontaneous multiscale synergies emerging in complex living systems when interacting with cooperative/competitive environments. This conception of educational agents (students, teachers, institutions) changes the understanding of the teaching/learning process and the traditional roles assigned to each agent. Under such an understanding, the design and co-design of challenging and meaningful learning environments is a key aspect to promote the spontaneous emergence of multiscale functional synergies and teams (of students, students and teachers, teachers, institutions, etc.). According to coordination dynamics, cooperative and competitive processes (within and between systems and their environments) are seen not as opposites but as complementary pairs, needed to develop collaborative creativity and increase the functional diversity potential of teams. Adequate manipulation of environmental and personal constraints, nested in different level and time scales, and the knowledge of their critical (tipping) points are key aspects for an adequate design of learning environments to develop synergistic creativity.

This work provides the children’s view on the measures of social distancing and massive school closures. However, without doubt, it also shows children’s and adolescents’ potential to empower themselves in complex situations which put the world’s schools in an unprecedented crisis. In addition, it shows the opportunity to take into consideration a joint construction of a society from the germ of its citizenship: children.
Spatial Dependence Evaluation of Agricultural Technical Efficiency—Based on the Stochastic Frontier and Spatial Econometric Model
Authors: Yin Ziqi , Wu Jianzhai
Published: March 2021

In recent years, through the implementation of a series of policies, such as the delimitation of major grain producing areas and the construction of advantageous and characteristic agricultural product areas, the spatial distribution of agriculture in China has changed significantly; however, research on the impact of such changes on the efficiency of agricultural technology is still lacking. Taking 11 cities in Hebei Province as the research object, this study examines the spatial dependence of regional agricultural technical efficiency using the stochastic frontier analysis and spatial econometric analysis. The results show that the improvement in agricultural technical efficiency is evident in all cities in Hebei Province from 2008 to 2017, but there is scope for further improvement. Industrial agglomeration has statistical significance in improving the efficiency of agricultural technology. Further, there is an obvious spatial correlation and difference in agricultural technical efficiency. Optimizing the spatial distribution of agricultural production, promoting the innovation, development, and application of agricultural technology, and promoting the expansion of regional elements can contribute to improving agricultural technical efficiency.

Published: March 2021

Brackish lagoons are highly productive systems that support fishing and aquaculture activities with important revenue. At the same time, they function as fundamental habitats for the conservation of a number of species that use lagoons for reproduction and feeding. The present study aims at describing the seasonal structural and functional variations of fish communities in the Fattibello lagoon, a small but important nursery ground of the Po River delta (northern Italy), historically exploited for fishing. The fish community was sampled monthly over a six-years’ period (2009–2014). The results were normalized in catch per unit of effort (CPUE) and are expressed both as individual abundances (ind/CPUE) and biomass (g/CPUE). Higher biodiversity levels were observed in autumn, when both lagoon residents and marine species coexist, and summer, for individual abundances and biomass. Biomass was a better descriptor than individual abundance of the functional use of the lagoon. In autumn, the lagoon resident species increased significantly, while marine feeding ground species decreased. Vice versa, lagoon residents decreased in winter, when the lagoon were mainly used as feeding ground by marine fishes. Marine migrating species were present throughout the whole year. Overall, the lagoon serves as (i) reproduction habitats for different species, as well as habitat for the pre-reproductive period for the European anchovy; (ii) nursery grounds for a number of commercial species; and (iii) habitats for lagoon resident species, supporting them for the whole life cycle. Overall, the results highlight the fundamental conservation role of the lagoon throughout the whole year, and that seasonal structural and functional patterns of fish communities should be carefully considered when seeking to harmonize direct uses, such as fishing and bivalve farming, as well as nature conservation.

Published: March 2021

This review outlines the available data from the work of our group on renal hemodynamics, function, and oxygenation in patients who are critically ill with acute renal dysfunction, such as those with postoperative AKI, those in early clinical septic shock, in patients undergoing cardiac surgery with cardiopulmonary bypass, or in patients undergoing liver transplantation. We also provide information on renal hemodynamics, function, and oxygenation in patients with chronic renal impairment due to congestive heart failure. This review will argue that, for all of these groups of patients, the common denominator is that renal oxygenation is impaired due to a lower renal oxygen delivery or a pronounced increase in renal oxygen consumption.

The Role of Entrepreneurial Self-Efficacy and Entrepreneurial Passion in Firm Performance
Authors: Saksamrit Nattanan , Sripongpun Kullanun
Published: March 2021

Objective - This research clarifies how entrepreneurial self-efficacy (ESE) affects performance, and entrepreneurial passion (EP) may vary the ESE- firm performance relationship as a mediator.
Methodology/Technique – The data was collected using a questionnaire distributed to 400 entrepreneurs in Sakon Nakhon, Nakhon Phanom, and Mukdahan Province, Thailand. All measures had acceptable Cronbach’s alpha reliabilities. Descriptive statistics, mean, and standard deviation were used to analyze the data. The conceptual model and hypotheses were tested by using linear regression analysis. Confirmatory factor analysis was used to test construct validity.
Finding – The results show that the entrepreneurial self-efficacy had no effect of multicollinearity in the independent variables (Hair et. al., 2014). Therefore, it was possible to test the equation analysis based on the hypothesis using linear regression. In terms of direct relationship testing, entrepreneurial self-efficacy directly had a significant positive impact on firm performance and passion. In addition, entrepreneurial passion directly influenced firm performance. In terms of indirect relationship testing, entrepreneurial passion is a partial mediation for entrepreneurial self-efficacy and firm performance.
Novelty – This paper examines how self-efficacy (ESE) affects firm performance and how self-efficacy (ESE) affects firm performance when mediated by passion. This study may provide for higher accomplishment and greater performance.

Published: March 2021

Objective - This research seeks to examine the purchase behaviour of environment-friendly automobiles. It also identifies the key factors affecting the purchase intention of green vehicles. The study adopted a quantitative approach, and primary data was analysed on Smart PLS3. The researcher utilised a non-probability sampling technique to select the most appropriate sample for this study. This type of sampling is also known as purposive sampling, deliberate sampling, and or judgement sampling. Independent variables of this study include environmental attitudes such as; environmental knowledge, environmental values and responsibility feeling. These variables were tested against purchase intention, which is regarded as a dependent construct of this study.
Finding – Based on the findings, all the proposed hypotheses of this study are proven significant. Environmental knowledge has a positive effect on environmental values. Environmental values have a significant effect on the formation of a responsibility feeling. Responsibility feeling has a significant effect on the purchase intention of green vehicles.
Novelty – Individuals who possess adequate knowledge about their environment are likely to develop environmental values, which then transforms into a responsibility feeling towards the environment and then predict the purchase intention of environment-friendly automobiles. Citizens should thus be equipped with adequate knowledge about environmental issues, through formal and informal education, and through socialization agencies and awareness campaigns, as this will help in boosting pro-environmental and sustainable human behaviours.

To improve the usefulness of the data, the raw images acquired during non-destructive testing should be processed by image processing techniques. In this paper, by Frequency Modulated Thermal Wave Imaging, we use the image fusion technique to boost the detection capability of defects in a GFRP sample with 25 squared Teflon inserts of different sizes positioned at various depths. In applications such as detection, image segmentation is useful where it is difficult to process the entire image at a time. In this paper, Adaptive Thresholding Image segmentation is used to classify the delamination in Thermographic Images of Infrared Non-Destructive Research on images captured at two different times. Image fusion is later applied to segmented images. Image fusion is used to merge two or more pictures of a different focus and to provide the best picture quality. Fusion is carried out using the Basic Averaging Method here. Using Relative Foreground Area error, the performance of the proposed method is quantitatively assessed. The region and shape of an object are important parameters in the case of Non-Destructive Evaluation. Such parameters are contrasted with current methods of segmentation.

Reliability is the most important factor of distribution system and this system should be operated economically with low customer loads interruption. This is because that the distribution system gives supply to customers from transmission system. There are some power quality issues due to the failures of components in distribution system. Researchers are going on to assess the reliability of the power system. In the power system, reliability evaluation is an important aspect in complete electric distribution system planning and operation. Due to the extreme scale of problem, it is not possible to conduct reliability on complete power system, it is performed independently. Hence, In this paper, the reliability of distribution system is evaluated by using an analytical method is described and is applied to the IEEE RBTS BUS-6. Development of reliability model of distribution system using Electrical Transient Analyzer Program (ETAP) software is developed. And the Distributed Generation is introduced for the improvement of reliability. Reliability indices are such as System Average Interruption Frequency Indices (SAIFI), System Average Interruption Duration Indices (SAIDI), Customer Average Interruption Frequency Indices (CAIFI), Customer Average Interruption Duration Indices (CAIDI), Energy Not Supplied (ENS), Average Service Availability Indices (ASAI), etc. The performance of reliability of the system is shown by these indices

Decentralized cloud storage reflects a significant change in large-scale storage performance and economy. Removing central control enables users to store and exchange data without depending on third-party storage [16] providers. Decentralization reduces the possibility of data failures and outages while increasing object storage protection and privacy at the same time. Decentralized cloud storage is where individuals or groups encouraged to enter, store, and keep data available are stored on a decentralized network through several locations. The servers used, rather than a single organization, are hosted by individuals. In this paper, an information dispersal algorithm is applied on decentralized cloud storage to reduce spatial overhead, which provides more efficient performance compared to the existing methodologies.

Interest in philosophy and the humanities increased after the Second World War, especially in the West, as the critical movement began to reconsider the Western intellectual and philosophical heritage, and emerged approaches known as” postmodernism“, as critical foundations of Western cultural thought, and a product of that cultural and cognitive movement known as” postmodernism"; the concept of postmodernism, which is central This term is associated with a very diverse group that is rarely associated with each other with common things. The idea of postmodernism appears in a critique of the literary and philosophical trends on which modernism was based, and some theorists and philosophers believe that postmodernism is closely related to the social and political transformations that took place in industrial societies such as the postindustrial or knowledge society. Deconstruction is important critical movement as well as controversial, and no theory in literary criticism has provoked waves of admiration and created a state of aversion and resentment as well, as deconstruction has done in contemporary literary thought. Deconstruction emerged in the 1960s as a reaction to structuralism, the dominance of language, the centralization of the mind, and the dominance of linguistics over all fields of knowledge, and from the 1970s deconstruction became a literary critical methodology, and a mechanism for evaluating rhetoric and interpretation. Deconstructionism is mainly a critique of the structural proposition, which has been working to reveal the basic structures responsible for the most noticeable features of social and cultural interaction, since deconstructionism consistently negates the meaning in the text system and analyzes the margins, gaps, expectations, contradictions and conclusions within the texts, as formulations that contribute to the disclosure of the background of language and structure.

This study is aimed to improve students' choreography skills. Since students are still constrained in coming up with ideas, creative imagination in choreography as a result they have minimal choreographic results. The diversity of students' input in the Sendratasik Department is one of the factors causing the low creativity and productivity of students' choreography. It means that the students have different basic abilities of choreography so that they have a minimum of ideas and creativity in learning choreography. Even though the lecturer has used his competence as a choreography lecturer, however in reality the lecturer is more likely and always uses a learning model that has not been able to build students to be more motivated and quick to find ideas and find stimulation of imagination, so they are slow in generating ideas and finding stimulation of the imagination. This type of research is development research or what is called Research and Development (R&D) with qualitative and quantitative approaches. The Productive Creative-based Choreography Learning Model in this study has produced a valid, practical, and effective model because it has an impact on increasing the choreography ability and learning motivation of students.

Supply chain management (SCM) is a crucial strategic driver for increasing operational performance and maximizing the achievement of organizational objectives, such as improved productivity, improved customer service and enhanced profitability. The age of both market globalization and outsourcing has started, and many companies tend to manage their supply chain and logistics activities. Most of these organizations understand that SCM needs to be tested for its performance in order to create an effective and efficient supply chain. Since e-commerce buys and sells goods over the Internet, in addition to payment between the two parties, it is the transfer of goods that also needs to occur in a correct and timely manner, hence the need for the supply chain. The supply chain is the most critical element for companies to boom in e-commerce, which needs to be quick, uninterrupted and safe. The competition is fierce because not one or two, but hundreds of e-commerce companies are competing for market share, each finding and creating specific strategies for sale and distribution. The present study is an attempt to examine various issues of supply chain management in the E-Commerce context. Although there is a lack of literature in this context, the current study critically reviewed the current literature and built a questionnaire with the inputs from leading e-commerce managers by identifying the main supply chain management issues such as preparation, inbound, outbound, returns, orders and trying to find the effect of these variables on organizational efficiency. A sample size of 100 employees employed in supply chain departments at different levels of five leading e-commerce fashion & lifestyle organizations in India was taken for a questionnaire survey as a sampling unit. The study found fascinating insights of supply chain management in e-commerce, which eventually benefit the marketers to design more effective supply chain management. Further, this study becomes a gap filler for the existing literature deficiency in the Indian context and an e-commerce context.
