Authors: Saputro Bryanna Infinita L. , Dhiya Rakasiwi Muhammad Ilham , KhairaniSiregar Astrid Mariam
Published: July 2023

Malnutrition is part of the geriatric giant and a major concern among community-dwelling elderly individuals. Improper intervention of this problem can have detrimental effects on the elderly. Monitoring nutritional intake plays a vital role in managing malnutrition. Telemedicine has been widely applied for managing chronic diseases and gained prominence during the COVID-19 pandemic as a remote health monitoring method. This scoping review aims to identify the advantages and limitations of implementing telemedicine for addressing malnutrition in community-dwelling elderly. This study reviewed the literature obtained through a systematic search of PubMed and ScienceDirect databases, supplemented by manual searches based on specific inclusion criteria.  Two randomized controlled trials (RCTs) assessing the application of telemedicine for malnutrition were identified. The forms of telemedicine used were telecare and set-top boxes on television. The interventions included nutritional monitoring and specific interventions for each patient. However, high patient dropout rates indicated low patient compliance. Nevertheless, the application of telemedicine demonstrated improved patient compliance with nutritional intake guidelines. Limitations of telemedicine implementation included low motivation, technological constraints, and physiological constraints. Telemedicine may be used as a tool for monitoring nutritional intake among malnourished geriatric populations.

Published: July 2023

Analog rice, also known as artificial rice, is a rice substitute made from a combination of local flours, including sorghum flour, mocaf flour, and glucomannan. Incorporating Moringa leaves into analog rice flour offers potential health benefits due to its anti-diabetic and antihyperglycemic effects, which lowers blood sugar levels and HbA1C levels in individuals with Diabetes Mellitus. This study aims to develop analog rice using a combination of sorghum, mocaf, and glucomannan flour and to determine its sensory properties and fiber content. This study employed an experimental design, with Moringa leaf flour substitutions divided into P1 (0%), P2 (2%), P3 (4%), P4 (6%), P5 (8%), and P6 (10%), using a Completely Randomized Design (CRD). Sensory evaluation was done using the hedonic test, involving 25 trained panelists who assessed taste, aroma, color, and texture. Fiber content was analyzed using the enzymatic gravimetric test. Data were analyzed using a one-way ANOVA test, followed by Duncan’s test if p<0.005. The results showed a significant effect of Moringa leaf flour substitution on sensory evaluation and fiber content (p<0.001 for all comparisons). Based on sensory evaluation, panelists preferred analog rice P2 (2%). The fiber content of analog rice with Moringa leaf flour substitution ranged from 11.16 to 13.65% for insoluble dietary fiber, 0.60 to 0.99% for soluble dietary fiber, and 11.80 to 14.62% for total dietary fiber. Moringa leaf flour substitution had a significant difference in sensory evaluation and fiber content of analog rice. The highest preference level was found in P2 (2%) analog rice, while the highest total fiber content was found in P5 (8%) analog rice.

Published: July 2023

Elevated malondialdehyde (MDA) levels indicate the occurrence of cell membrane oxidation. Calorie restriction is known to extend life expectancy. This study aims to investigate the effect of calorie restriction on MDA levels in young and old rats. An experimental approach was employed using Rattus norvegicus Wistar strain as the experimental animals, with a pre-post-test control group design. A total of 28 white rats were included in this study and were divided into four groups. The control groups, Group A and Group B, received standard feed and unrestricted access to distilled water, while the treatment groups, Group C and Group D, were fed with a 40% reduction in calorie intake and distilled water. Data analysis was performed using SPSS 21.0 (SPSS, Inc., Chicago, IL) with a 0.05 significance level. The results showed a difference in MDA level changes between group B (control group) and group D (treatment group) (p<0.05). This study concludes that MDA levels are higher in the elderly compared to young rats, and a 40% calorie restriction can reduce MDA levels.

Published: July 2023

An analysis of the physical processes occurring during the emission of sound waves by electrothermal sound sources (thermophones) showed that a thermophone is a reversible physical system. This made it possible to determine the conditions under which the convertion of an acoustic signal into an alternating electric current can be carried out on the thermophone active element and, hence, the system will respond to an external acoustic field. Keywords: acoustic signal, active element, metal film, electric current, electrothermal receiver.

Authors: Fulton Caitlin , Smith Kylie , Barr Christopher , George Stacey
Published: July 2023

Aim and Background: Sexuality is an important aspect of being human, and is affected for people following trauma injuries. This study aimed to examine how sexuality is addressed during rehabilitation following traumatic motor vehicle injuries and to identify barriers to provision of this service. Methods: A convergent mixed methods approach with concurrent timing and an independent level of interaction was used to examine the perspectives and experiences of clients and clinicians towards addressing sexuality. A questionnaire was completed by eligible clients (n = 21) and semi-structured interviews (n = 10) were conducted with clinicians.  Questionnaire data were analysed using descriptive statistics (frequency, means and SD) to provide an outline of sociodemographic and injury related information. Interview data from clinicians were analysed thematically. Results: Sexuality was described as being impacted for over half of clients. One third reported that sexuality was addressed as part of their rehabilitation. Core themes identified from the interviews of clinicians included: (1) ‘whole person’ approach, (2) timing, delivery and responsibility of discussions, (3) culture and comfort, and (4) future tools and skill sets. Conclusion: Clinicians and clients agreed that sexuality was important but inadequately addressed during rehabilitation. Clinicians were lacking comfort, training and resources to address sexuality consistently with clients. Sexuality should be addressed at multiple stages of rehabilitation to grant service-users the option for these discussions to occur.

Authors: Quinchía Figueroa Adriana María , Valencia-García Marco Fidel
Published: July 2023

Los residuos agroindustriales representan más del 40 % de los residuos mundiales. En Antioquia, estos llegan a las 400 t/ha, donde las flores son una línea importante y también los residuos de girasol, de los cuales solo se utiliza la flor y se deja el tallo como un residuo que aún no ha sido valorizado. En este trabajo se extrajeron las fibras del tallo residual del girasol para su incorporación a materiales compuestos de matriz cerámica, donde la adherencia de las fibras puede evitar las fisuras por contracción, lo cual actualmente se corrige a partir de fibras sintéticas. Durante la investigación, se evaluó el tratamiento químico de las fibras con Na2SiO₃, Ca(OH)₂, Ca(ClO)2, NaHCO₃ y NaOH, y se contemplaron los tiempos de secado en horno y su posterior tratamiento de carbonatación, lo que mejoró las condiciones de resistencia a la tracción de la fibra hasta en un 57 %. La comparación morfológica de las fibras se realizó mediante pruebas sem y ftir, lo que mostró diferencias significativas antes y después de los tratamientos. Finalmente, los resultados mostraron que las fibras naturales del tallo de girasol son comparables con otras fibras naturales con potencialidad para múltiples aplicaciones, incluyendo la mejora de compuestos de matriz cerámica, donde la fibra carbonatada aumentó la resistencia a la compresión de probetas de hormigón en un 20 % y la resistencia a la flexión en un 22,6 %, demostrando así que esta aplicación promete ser una alternativa viable para la valorización de la fibra de girasol como residuo agrícola con proyección comercial, contribuyendo a la economía circular.

Authors: Patel Khushi S , Corbett Cynthia F , Combs Elizabeth M , Donevant Sara B , Selph Margaret J , Gibson Lynette M , Dawson Robin M , Sheth Amit P , Hughes Ronda G
Published: July 2023

Background

As of May 2023, the novel SARS-CoV-2 has claimed nearly 7 million lives globally and >1.1 million lives in the United States. Low-income populations are often disproportionately affected by risk factors such as lifestyle, employment, and limited health literacy. These populations may lack the knowledge of appropriate infection precautions or have reduced access to care during illness, particularly in countries without universal health care.

Objective

We aimed to explore the perceptions and experiences of COVID-19, including symptoms and risk factors among uninsured individuals seeking care at a free medical clinic, and to obtain respondents’ perceptions of and suggestions for adapting a mobile health (mHealth) app to an uninsured population known to have low health literacy.

Methods

We conducted a prospective multimethod survey study with a convenience sample of uninsured adults seeking care at 3 free clinics in the United States. Respondents were questioned about their risk for and awareness of COVID-19 symptoms, COVID-19 testing, current technology use, and the use of technology to facilitate their health regarding COVID-19. Data were analyzed using descriptive statistics (eg, frequencies and mean differences). In addition, a small subset of respondents from one of the clinics (n=10) participated in interviews to provide feedback about the design of a COVID-19 web-based smartphone (mHealth) app.

Results

The survey respondents (N=240) were 53.8% (n=129) female, were primarily White (n=113, 47.1%), and had a mean age of 50.0 (SD 11.67; range 19-72) years. Most respondents (162/222, 73%) did not think that they were at risk for COVID-19. Although respondents reported only moderate confidence in their knowledge of the short- and long-term symptoms of COVID-19, their knowledge of the symptoms aligned well with reports published by the Centers for Disease Control and Prevention of the most common acute (590/610, 96.7%) and long-term (217/271, 80.1%) symptoms. Most respondents (159/224, 71%) reported an interest in using the mHealth app to gain additional information regarding COVID-19 and available community resources. Respondents who were interviewed provided suggestions to improve the mHealth app but had overall positive perceptions about the potential usefulness and usability of the app.

Conclusions

It was encouraging that the knowledge of COVID-19 symptoms aligned well with the reports published by the Centers for Disease Control and Prevention and that respondents were enthusiastic about using an mHealth app to monitor symptoms. However, it was concerning that most respondents did not think they were at a risk of contracting COVID-19.
Results and Methodological Implications of the Digital Epidemiology of Prescription Drug References Among Twitter Users: Latent Dirichlet Allocation (LDA) Analyses
Authors: Parker Maria A , Valdez Danny , Rao Varun K , Eddens Katherine S , Agley Jon
Published: July 2023

Background

Social media is an important information source for a growing subset of the population and can likely be leveraged to provide insight into the evolving drug overdose epidemic. Twitter can provide valuable insight into trends, colloquial information available to potential users, and how networks and interactivity might influence what people are exposed to and how they engage in communication around drug use.

Objective

This exploratory study was designed to investigate the ways in which unsupervised machine learning analyses using natural language processing could identify coherent themes for tweets containing substance names.

Methods

This study involved harnessing data from Twitter, including large-scale collection of brand name (N=262,607) and street name (N=204,068) prescription drug–related tweets and use of unsupervised machine learning analyses (ie, natural language processing) of collected data with data visualization to identify pertinent tweet themes. Latent Dirichlet allocation (LDA) with coherence score calculations was performed to compare brand (eg, OxyContin) and street (eg, oxys) name tweets.

Results

We found people discussed drug use differently depending on whether a brand name or street name was used. Brand name categories often contained political talking points (eg, border, crime, and political handling of ongoing drug mitigation strategies). In contrast, categories containing street names occasionally referenced drug misuse, though multiple social uses for a term (eg, Sonata) muddled topic clarity.

Conclusions

Content in the brand name corpus reflected discussion about the drug itself and less often reflected personal use. However, content in the street name corpus was notably more diverse and resisted simple LDA categorization. We speculate this may reflect effective use of slang terminology to clandestinely discuss drug-related activity. If so, straightforward analyses of digital drug-related communication may be more difficult than previously assumed. This work has the potential to be used for surveillance and detection of harmful drug use information. It also might be used for appropriate education and dissemination of information to persons engaged in drug use content on Twitter.

A competitive device audit for use in intensive psychiatric settings (Preprint)
Authors: Iacobelli Peter , Westheimer Jessa , Patriquin Michelle
Published: July 2023

UNSTRUCTURED

As the use of technology in mental healthcare becomes more prevalent, traditional methods of care in inpatient psychiatric settings are being questioned for their efficacy (Hirschtritt & Insel, 2018). Wearable devices to monitor physiological patterns associated with mood changes have received a significant amount of study over the past decade, and are widely considered a viable, less invasive alternative to current patient care practices (Hickey et al., 2021). As the demand for wearable devices for mental health assessment and intervention continues to rise, the number of brands and models does as well. The ever-growing market of options can make wearable device-based research both more costly and more time consuming (Turukalo et al., 2019). Our aim in this paper is to compile relevant information about major wearable device distributors and to offer a framework that can guide researchers toward choosing the right wearable device for their inpatient psychiatric or intensive mental healthcare setting.

Authors: S Nischitha B , Nayak Madhu M , J Vishwesh
Published: July 2023

Abstract: Agriculture plays a major role in the Indian Economy. Over 50 percent population majorly depends on agriculture as their income. Farmers have been cultivating crops for thousands of years on the same land. Here, crop choice is a crucial component of agriculture. Early crop selection is an option available to farmers. However, it is challenging for farmers today to determine the ideal fertilizer due to continual environmental changes. This artificial intelligence chatbot is designed to give the information on crops and fertilizer prediction in both Kannada and English languages. It employs logistic regression, ANN, and natural language processing (NLP) methods. The user enters the inputs like environmental condition, crop type, soil type, and soil nutrients then the chatbot provides an accurate fertilizer name. If a crop is unsuitable for that area this will also be recommended to the farmers. The web application is regularly updated to guarantee that the chatbot has access to the most recent data and can provide users the most relevant answers. This project is very beneficial to farmers since it allows them to choose the proper fertilizer to begin with the product cycle and increase the yield

Published: July 2023

Abstrct: Groundwater is one of the important sources of potable water supply in rural India. The study area of Makrana block is located in the south-eastern part of Nagaur district of Rajasthan covering about 1140 sq. km. area. The marble from the Makrana town gets the GHSR (Global Heritage Stone Resources) status recently from the IUGS. The study area experiences arid to semi-arid type of climate. Older alluvium, Quaternary Alluvium and Schist are important aquifers occur in Makrana block. Groundwater occurs under unconfined to semi-confined conditions. Groundwater quality and depth of water varies widely in Makrana block. High concentration of fluoride and nitrate are major quality problem associated with groundwater and having adverse effects on human health. High concentration of fluoride in a particular belt is so remarkable that the term BANKA PATTI (a strip of land where deformed people reside) has been in used covering parts of Parbatsar, Makrana and Degana blocks of Nagaur district wherein some villages the fluoride concentration in groundwater is over 4 ppm. The concentration of Fluoride mainly comes from Schists, Gneiss and Limestone of Proterozoic age. Higher concentration of fluoride affects metabolic activities of an individual which may cause skeletal and dental fluorosis. The disease fluorosis is non curable but preventable

Este artículo describe y analiza el sistema de actores, actividades y tareas que componen la producción y comercio de cocaína en el Perú. Basado en el análisis de entrevistas a informantes clave y reportes sobre el comercio de cocaína, el resultado principal muestra un sistema que funciona como una lógica segmentaria y dispersa, con actores que compiten entre sí y que se organizan de manera coyuntural. Esto discute la idea de un monopolio concentrado en grandes organizaciones criminales piramidales y transnacionales que controlan el mercado, y muestra, más bien, el carácter difuso de un sistema que asemeja una economía de mercado de commodities globales, con diversos agentes tercerizados y parcelas de trabajo.

Authors: B Chaudhari Nilesh , G Zalte Amar , S Gulecha Vishal
Published: July 2023

The present research work aims to prepare and characterize solid lipid nanoparticles (SLN) containing rosuvastatin calcium (RT). We aim to use a novel microwave-assisted microemulsion technique to produce Rosuvastatin-loaded SLN. The characterization of the optimized formulation of RTSLN was carried out by employing Fourier-transformed infrared spectroscopy (FTIR) and Differential scanning calorimetry (DSC) studies showed that there was no chemical interaction between drug (Rosuvastatin Calcium) and lipid (GMS), XRD indicated the amorphization of RTSLN formulation. In contrast, scanning electron microscopy (SEM) studies indicated that Rosuvastatin Calcium loaded SLNs are spherical, discrete, and homogeneous. In vitro and ex vivo drug release studies showed sustained drug release action. The effect of dependent variables such as entrapment efficiency (EE), particle size, and independent variables like % GMS and Poloxamer 407 was observed using a 32-factorial design approach. Optimized formulation was selected based on the 2D & 3D counter and surface response plots. The prepared formulations show percentage entrapment efficiency within the range of 53 to 78%, particle size in the 254.2 to 863.4 nm, and in vitro drug release was found to be 79.8%. Also, ex vivo absorption was 76.7 % for 8 hours. The need of the research work is to use microwave energy over conventional heating to prepare SLNs also helps to resolve problems associated with conventional colloidal drug delivery systems, which leads to improved drug bioavailability.

PYGMALIONIZATION: DO ACTION FIGURES, NENDOROIDS, AND PLUSHIES OF FILMS AND GAMES TELL A STORY?
Authors: Prakoso Mohammad Romdhoni , Yanuasari Rizki Adi , Purnama SF Lukfianka Sanjaya , Prihastiwi Lusiana
Published: July 2023

Studies on merchandise or merch as paratexts that serve as nano-narratives in adaptation context are under investigated. We argue that treating merchandise of hyped films and games as in the mentioned fashion might disclose a novel perspective in perceiving them as a narrative text.  Employing the theories of paratextuality by Genette, ergodic literature by Aarseth, ludic adaptation by Purnomo et al., franchising storytelling by Parody and nano-narratives by Petten on a corpus of merch from forty animated films and games, we proposed a neologism that we dubbed pygmalionization. This perspective refers to adapting animated films and games into toy-based merch e.g. action figures, nendoroids, and plushies and treating them as paratexts with the purposes of serving nano narratives and of extending the narrative experiences methectically and metathectically to the general audiences and fans through transtylization. This study is expected to provide insights for adapted merchandise makers and scholars in regard to treating the merchandise as a paratext with nano-narrative functions.

and its attributable risk factors highly valuable. The aim of this study
is to estimate the burden of leukemia in children and adolescents, as
well as the social-demographic status, for 21 regions around the world
from 1990 to 2019. Methods We collected data of childhood and adolescent
leukemia from the Global Burden of Disease (GBD) 2019 including,
incidence, death, and Disability-adjusted life-years (DALYs). We also
conducted an analysis of the Joinpoint model to estimate the time trend
of incidence, death, and DALYs rate of leukemia. Results According to
our analysis, the middle Socio-Demographic Index (SDI) experienced the
highest decrease in incidence rate between 1990 and 2019, with an
average annual percent change (AAPC) of -2.8* [95% CI, -3.0, -2.6].
On the other hand, the High-middle SDI witnessed the highest decrease in
death rate, with an AAPC of -3.1* [95% CI, -3.30, -3.00].From 1990
to 2019, the incidence, mortality and DALYs of leukemia decreased by
51.46%, 53.87% and 54.46%, respectively, for both genders globally.
We showed that DALYs of children leukemia is 155.98 (95%UI 127.18,
182.64) for global male, however, global female leukemia DALYs is
117.65(95%UI 102.07, 132.70). We also observed that in the two most
representative regions of East Asia and Eastern Sub-Saharan Africa in
2019. Conclusions Despite the observed decline in the incidence,
mortality, and DALYs of leukemia over the last three decades, the burden
of childhood and adolescent leukemia remains high, particularly in areas
with lower SDI.

We report an hemodialysis MDR HIV-infected patient switched to
fostemsavir with lenacapavir plus lamivudine for more than a year. She
maintained a suppressed viral replication and didn’t present any
clinical or biological drug-related side effects. The combination of
lenacapavir plus fostemsavir looks promising in terms of safety and
efficacy even in patients with end-stage renal disease awaiting renal
transplant. Both drugs are first in class ARVs so that there is no cross
resistance with previous drugs, maintaining their efficacy against MDR
HIV.
Labour market reforms in brazil (2017-2021): An analysis of the effects of recent flexibilization on labor market legislation
Authors: Oreiro José , Gabriel Luciano , D’Amato Stefan , da Silva Kalinka
Published: July 2023

The main objective of this work is to analyze the effects of Brazilian Labor
Market Reform (BLMR) in the short run and, based on identified changes in
the economy in recent decades, to verify how these changes have affected the
labor market. Four methods were used in a complementary way: (i) employment
quality index; (ii) panel data estimation method; (iii) synthetic control
method and (iv) microdata analysis. We observed that there was no
considerable increase in the quality of employment and formal employment and
the rate of unemployment did not decrease after the implementation of these
changes. Part of this dynamic is cyclical and related to exogenous shocks,
such as the COVID pandemic on the Brazilian economy. Finally, according to
econometric analysis, the rate of unemployment in Brazil is more responsive
to investment rates and the business environment than to unit labor cost and
changes in labor legislation.
Structural change, labor market and employment in brazil after the 2017 labor market reform

Published: July 2023

The objective of this study is to analyze the effects of the set of measures
adopted by the labor reform of 2017 on the generation of employment and
income in Brazil. The study is based on the literature that highlights the
importance of structural change in employment as a key element for economic
growth and development, emphasizing that in Brazil, there is still a view
that the labor market should take on more flexible work relationships to
advance in the improvement of jobs, levels of employment, productivity and
income. Subsequently, the article summarizes and critically comments on the
main measures of the labor law reforms adopted in post-2017 Brazil. Finally,
it presents an analysis of the behavior of the labor market in Brazil
between 2012 and 2022 based on data from the PNADC/IBGE survey. The main
results of the survey confirm that the labor reform of 2017 has not shown
advances in labor market indicators or in the main macroeconomic aggregates
of the country. In contrast, the data suggest deterioration in the
indicators of employment, income and allocation of workers in occupations
with low productivity and income characteristics.
The impacts of the Brazilian Labour Reform on employment, output, and labour productivity

Published: July 2023

This paper discusses the role played by the recent Brazilian Labour Reform
(BLR) in conditioning the level and the rate of growth of employment, value
added and productivity in the Brazilian economy from 2017. Our main findings
are that after BLR, the share of informal employment, value added and
productivity increased, as well as those shares in low productivity sectors.
Furthermore, we show that the employment created in low-productivity sectors
(formal and informal) were moved to high-productivity sectors in the years
after the implementation of the 2017 labour reform, the aggregate levels of
value added and productivity would have been much higher than otherwise.

Introduction. Marginal seal or adequate marginal adaptation of material along
the cavity walls should be able to prevent leakage of tissue fluid and
consequently bacterial microleakage, terefore, it is considered as
significant factor for long term success of endodontic treatment. The aim of
this work was to test the marginal microleakage of newly synthesized
nanostructured biomaterials based on calcium aluminate, calcium silicate and
MTA with a dye penetration test after application the material to the
interradicular perforations of extracted teeth. Material and method. The
study included 48 extracted human maxillary and mandibular molars. Newly
synthesized nanostructured materials were tested: material based on calcium
aluminate, calcium silicate. Commercial calcium silicate cement (MTA
Angelus, Londrina, Brazil) was used as a control material. Marginal
microleakage was examined with a dye penetration test six months after
application of the material in experimentally prepared interradicular
perforations on extracted human molars. Penetration depth measurement was
analyzed with a binocular magnifier (Leica DM 500, Leica Byosistems).
Results are expressed in millimeters and statistically processed by applying
the analysis of variance for repeated measurements with the Sidak test.
Results. The lowest average penetration (mm) was for MTA (1.40 ? 0.63 mm),
and the highest for Ca aluminates (2.10 ? 0.63 mm), while for calcium
silicates an average color penetration of 1.73 ? 0, 67mm was recorded. By
testing intergroup differences in color penetration between groups, a
statistically significant difference between MTA and Ca aluminate was
obtained using Sidak?s test (t = -0.693; p = 0.036). No statistically
significant difference was recorded between MTA and Ca silicate, nor was
there a statistically significant difference between Ca aluminate and Ca
silicate. Conclusion. The lowest marginal microleakage, the best marginal
sealing, was recorded with the MTA material. The microleakage of calcium
aluminate-based materials was significantly higher compared to calcium
silicate and MTA.
Modeling the relationships between transformational leadership, teacher academic optimism, and teacher engagement: Evidence from the Serbian school context
Authors: Ninkovic Stefan , Djordjic Dejan , Olic-Ninkovic Stanislava
Published: July 2023

Although the construct of teacher engagement is acknowledged as important for
positive student and teacher outcomes, evidence about its determinants is
still scarce. The main aim of this study was to investigate the
relationships between transformational leadership, dimensions of teacher
academic optimism (i.e., self-efficacy, teacher trust in parents and
students, and academic emphasis), and teacher engagement. Data obtained from
420 primary and lower secondary school Serbian teachers were analyzed by
utilizing structural equation modeling with latent variables. The results
revealed that transformational leadership has positive effects on all
dimensions of teacher academic optimism. Transformational leadership was
directly associated with teacher engagement, although this relationship was
not strong. Also, transformational leadership was linked to teacher
engagement indirectly, via teachers? trust in parents and students and
academic emphasis. The present study suggests that transformational
leadership plays an important role in enhancing teacher engagement.
Therefore, by strengthening transformational leadership in the school, the
engagement of teachers is likely to be improved.

Authors: Hirzy Hanyda , Dellyana Dina
Published: July 2023

With the rapid growth of e-commerce, businesses face the challenge of optimizing their strategies to attract and retain customers, while avoiding the common pitfall of burning money due to inefficient practices. Therefore, the treatment for digital customers is different of offline customers. This thesis explores the 7 main factors why users are convenient in shopping via Tokopedia. Through a comprehensive review of literature, the thesis provides insights into the concept of consumers' reasons, needs and why it’s convenient to purchase via Tokopedia. The thesis then tries to give another insight into delivering the best services to its consumers by not only focusing on promotion but from another variable. In particular, the thesis focuses on the impact of trustworthiness, recommendation, promotion, brand ambassador, brand reputation, advertising, and delivery toward consumer purchase using quantitative methods. Quantitative data is obtained through a questionnaire survey with 350 respondents across Jakarta. The thesis will deliver new insights for Tokopedia for the further strategy to not only focus on promotion. The findings of the thesis demonstrate that Tokopedia strategy can focus on developing a more consumer-centric approach bigger than promotion.
