This research focuses on utilizing numerical simulation to analyse how modifications in the air jet diffuser shape impact the cooling efficiency of electronic parts. The main aim of this study is to understand the physical and thermal mechanisms involved in the process. The study consists in numerically predicting the physical and thermal field of a cubic-shaped obstacle placed in the centre of a square subjected to a resulting flow field created by a transverse flow and a perpendicularly oriented impacting jet. The computations were done at a Reynolds number of 3 410, analyzing three perpendicular impinging jets with the ratio of impinging and cross flow Reynolds numbers α = Rej /ReH having the values of 0.5, 1, and 1.5. The k–ω SST turbulence model was used in this investigation. The effectiveness of the methodology that was put into action was evaluated by referring to the findings derived from the experiments conducted by Masip and his team. Once the methodology was validated, we studied the effect of changing the geometric shapes of the impinging jet diffusers on the cooling efficiency. Three geometrical shapes of air diffusers were tested (circular, swirling and lobed). We noted that there is a direct correlation between flow morphology and cooling efficiency. The impact of the ratio α was analysed and found to have a significant effect on the cooling efficiency. As this ratio increases, the quantity of heat transfer increases in all three air jet diffuser cases. In relation to the lobed air jet, it was observed that the Nusselt number exhibits greater values when compared to the other air jet diffuser cases. Moreover, it was noted that the lobed air jet diffuser can enhance the heat transfer efficiency for α = 1.5 by more than 16.3 % compared to the circular air jet diffuser.

Positive State Controllability of Discrete Linear Time-Invariant Systems
Authors: Ouyadri Mourad , Laabissi Mohamed , Achhab Mohammed Elarbi
Published: March 2024

Positive state controllability is the controllability of systems where the state is positive and the input remains in ℝn. Under some conditions, we established a relation between the reachability map of systems with only the positive state and the reachability map of a related positive system where the state and input are both positive. Using this connection, necessary and sufficient conditions are obtained for the positive state reachability of discrete linear time-invariant (LTI) systems, and then we deduced the positive state controllability. These conditions are evaluated over some numerical examples that support the theoretical results.
Modified Integral Transform for Solving Benney-Luke and Singular Pseudo-Hyperbolic Equations
Authors: Elzaki Tarig M. , Chamekh Mourad , Ahmed Shams A.
Published: March 2024

In this article, we propose a technique based on modified double integral transforms used to solve certain equations of materials science, namely Benney–Luke (BL) and singular pseudo-hyperbolic (SP-H) equations. We have established some analytical results. This method can provide accurate one-step solutions, although the equations used may exhibit a singularity in the initial conditions. Some numerical examples have been discussed for illustration and to show the effectiveness of the technique for certain types of equations. We have developed an exact solution in just one step, whereas other approaches require several stages to succeed in a particular solution, making the proposed strategy particularly successful and straightforward to apply to various varieties of the B–L and SP-H equations.
Cytokine secretion in stem cells of cattle infected with bovine leukaemia virus
Authors: Szczotka Maria , Kuźmak Jacek
Published: March 2024

Introduction

Bovine leukaemia virus (BLV) is a Deltaretrovirus responsible for enzootic bovine leukosis, the most common neoplastic disease of cattle. It deregulates the immune system, favouring secondary infections and changes in the blood and lymphatic tissues. Blood homeostasis depends on functional haematopoietic stem cells (HSCs). Bone marrow is populated by these cells, which express CD34+ and CD35+ surface antigens and produce and release cytokines involved in the maintenance of haematopoiesis. The aim of the study was determination of the profile of cytokine production by CD34+ stem cells of cattle naturally infected with BLV.

Material and Methods

The HSCs were generated from the blood and lymphoid organs of cows infected with BLV and healthy control cows with immunomagnetic separation and anti-CD34+ monoclonal antibodies. Isolated CD34+ cells were cultivated for two weeks with interleukin (IL)-4 and granulocyte-macrophage colony-stimulating factor. The levels of IL-6, IL-10, IL-12p40, IL-12p70, interferon gamma (IFN-γ) and tumour necrosis factor alpha (TNF-α) were determined in culture fluid by flow cytometry.

Results

The expression of IL-6, IL-12p70 and TNF-α in blood HSCs was higher in BLV+ cows than in the control animals. In bone marrow HSCs of infected cows, IL-12, TNF-α and IFN-γ were more concentrated, but in these cows’ spleen HSCs only expression of IL-10 was elevated. In HSCs isolated from the lymph nodes of leukaemic cows, only TNF-α secretion was lower than in control cows, the other cytokines being more potently secreted.

Conclusion

Infection with BLV caused statistically significant differences in cytokine expression by HSC CD34+ cells.
Designing Knowledge Strategies for Universities in Crazy Times
Authors: Bratianu Constantin
Published: March 2024

The purpose of this paper is to analyze the challenges universities have during crazy times and to show how to design knowledge strategies to navigate successfully through the changing economic landscape. Crazy times mean times of rapid and unpredictable changes in the economic environment, times of crises, and disruptive phenomena. For such kind of new realities, the deliberate strategies designed for a predictable future cannot help anymore. They should be replaced by emergent strategies, which consider a moving time coming from the future towards us. Universities are knowledge-intensive organizations, and knowledge is a strategic resource. Designing knowledge strategies and integrating them into the university business strategies becomes a new necessity. Our research is based on a conceptual analysis of time perception and strategy design for strengthening the university competitiveness in a changing environment. We make use of the known-unknown matrix and search for those generic strategies which contribute to the renewal of intellectual capital and achieving a competitive advantage in the new global market of higher education. The quest for becoming a world-class university and the pressure of the ranking systems require a special focus on designing and implementing knowledge strategies.
Teleworking Perspectives for Romanian SMEs after the COVID-19 Pandemic
Authors: Grigorescu Adriana , Nicolae Andreea Mocanu
Published: March 2024

The crisis caused by COVID-19, made us rethink our perception of the way of life. Traffic restrictions, isolation, quarantine, the need for social distance have generated new behavior by transferring null activities in the online environment. The advantage today is that the 21st century is characterized by the presence of information technology and its rapid development. The telecommute proposed by Nilles (1994), became in 2020 a very topical concept, due to the special situation in which the whole of humanity is. Although both employers and employees have refused the teleworking formula for a long time, it has now become the only possibility to maintain an acceptable level of activity. The rapid evolution of ITC technologies and applications, the entry on the labor market of the M generation have contributed to the increase of favorability for telework, in 2018 it being included in the Romanian legislation. The methodology for this article was to analyze the Romanian Classification of Activities in the National Economy (CAEN) to find out in which domains do Romanian SMEs prefer to activate and to find out the resistance to telecommuting as a way of work by finding out which of these economic sectors have implemented day to day teleworking long ago and which will. An empirical analysis of every domain was complemented by the survey results to verify to which extent telecommuting is feasible in Romanian SMEs, especially during and after the Coronavirus pandemic. It was necessary to analyze of Eurofound statistics regarding living and working during the COVID-19 pandemic to find out correlations and differences between the authors’ findings and the EU27 baseline.
The Econometric Approach of the Impact of Public Investment in the Road-Infrastructure in the Economic Growth of Kosovo
Authors: Ziberi Besime , Miftari Florije , Omaj Leonita
Published: March 2024

Economic growth and public investments are considered the most challenging problems faced by most countries around the world, including Kosovo. Various assumptions have been made that better and higher-quality transport is essential for the country’s economic development. This study aims to analyze the relationship and the impact of public investments in road infrastructure on Kosovo’s economic growth taking into analysis also other macroeconomics aggregates such as Consumption, Investment, Exports, and Imports. Two important aspects have been addressed within the extensive literature review, namely theoretical analysis of different studies elaborating on elements regarding infrastructure in general, such as social and economic infrastructure, and road infrastructure in particular. To analyze the impact of public investments in road infrastructure and other macroeconomics aggregates over Kosovo’s economic growth, the econometric multiple regression model Ordinary Least Squares (OLS), the Pearson Correlation, and the Test for heteroskedasticity have been applied. The data used is secondary data obtain from the World Bank Indicators, Kosovo Agency of Statistics, and the Official Gazette of the Republic of Kosovo. All these models are tested with the STATA software program. Based on regression analysis, we can conclude that public investments in road infrastructure for Kosovo’s economic growth are non-significant as their effect is manifested in the long run, but all the other independent variables from the OLS model are significant and impact the GDP growth of Kosovo. The study comes with some other conclusions, suggestions and opens paths for future researchers.
Workers’ Satisfaction with Grievance-Handling Procedure: A Study on the Selected Garment Factories in Bangladesh
Authors: Aktar Serena , Alam Md. Mahbub Ul
Published: March 2024

Employees are the most important asset in the organization. There should always be a good relationship between employer and employee. If employees are happy in the organization, then the organization can move towards success. Satisfaction towards grievance handling procedure is important in this regard since one of the most important consequences of mishandling of grievances is labor unrest. An employee’s grievance can be over the wage and salary, working hours, condition of work premises, employment conditions, etc. Keeping the views in mind, this study was conducted to examine the level of satisfaction towards different dimensions of grievance handling procedure and its influence on overall satisfaction among workers in some selected factories in the Readymade Garments (RMG) sector in Bangladesh. Data was collected using the Grievance Handling Procedure Questionnaire. A total of 284 garment workers from different garment factories located in Dhaka, Gazipur, and Narayanganj took part in the survey. Measures of central tendency, dispersion, and association have been used as part of descriptive statistics while multiple linear regression analysis has been used to identify significant predictors of turnover intention. The results indicated that four dimensions of grievance handling procedure, i.e., a decision given, time taken for solving grievance, follow up mechanism, and attitude of supervisors significantly predict workers’ overall satisfaction. However, structural features of the grievance procedure were found statistically insignificant. Finally, it was concluded that if managers and supervisors are well trained and workers’ grievances are handled effectively, they will be encouraged, assured, and will have positive feelings towards their organization and this would increase their overall satisfaction and, thereby, productivity.
Income Inequality and Economic Growth in Algeria: Empirical Study during the Period 1980-2015
Authors: Ameur Assia Ameur , Seffih Sadek
Published: March 2024

In recent years, Algeria achieves significant progress in the economic and social condition of its population due to the improvement in most economic and social indicators, and the increase in the human development index from 0.577 in 1990 to 0.754 in 2018. However, this improvement is not equally shared between groups and different regions. Therefore, poverty and inequality persist and remain a major challenge of the Algerian government. In this paper, we attempt to study income inequality and its impact on economic growth in Algeria. To attend the aim of this study we explore the relationship between income inequality and economic growth over the period 1980-2015 based on the available data. Based on the recent theoretical and empirical studies, we use Autoregressive Distributive Lags (ARDL) model to explore the long-run relationship, and Error Correction Model (ECM) for the short-run dynamics, the results indicate that economic growth as measured by the annual per capita GDP growth rate is associated negatively and significantly with inequality as measured by Gini coefficient, implying that in the long run, a 1% increase in income inequality will hurt economic growth in Algeria by nearly 0.52% in the long-run. The result obtained from the ECM model shows that the coefficient is equal to -1.23 and highly significant; this implies that the deviation for the short-run in economic growth is corrected by 123% percent over each year in a long time. These findings confirm the hypothesis that high inequality hurts the economic growth in low- and middle-income countries. Therefore, the Algerian government must adopt policies that favor economic growth and achieve greater equity in income distribution to ensure sustainable and inclusive growth.

From the interpretation of the findings using the panel data on the 14 selected Sub-Saharan countries, it was found that the increase in the number of registered mobile money agents per 100,000 adults led to an increase in the total number of people using the financial services per 100,000 adults in Sub-Sahara Africa. Furthermore, the relationship between the registered mobile money agents per 100,000 adults and the total number of people using financial services was proven to be significant at a 5% level of significance.
Strategic Management Initiatives that Promote Organizational Performance
Authors: Tolici Daniela
Published: March 2024

Organizational performance is broadly defined in the literature as a complex concept, which clusters a myriad of elements that promote performance in a modern organization. Previous empirical research has studied various strategic management initiatives and found that, separately, elements related to organizational culture, leadership, work environment, learning, change, innovation, and individual performance are influencing organizational performance. This study aims to connect various research models to identify and analyze the relationships between organizational culture, leadership, work environment, learning, change, innovation, and individual performance, on the one hand, and organizational performance on the other. This paper further shows that these variables are more effective when people are in the center of the organizational focus and suggests a model for the relationship process between these in a structured diagram.
Advancing Strategic Management through Sustainable Finance
Authors: Zamfiroiu Tatiana Păun , Pînzaru Florina
Published: March 2024

In a VUCA world dominated by volatility, uncertainty, complexity, and ambiguity as it is the case today, strategic management is redefined by the necessity to acquire strong organizational capabilities of agility and resilience, simultaneously with a prominent orientation toward adoption of measures destined to meet climate change and social challenges. The environmental, social, and governance (ESG) criteria are the new must when designing corporate programs, starting to be adopted by small and medium enterprises (SMEs) as well, but with different success rates. High-profile ESG programs tend to be launched and developed mainly by organizations that integrate them into evolving business models and strategies, thus translating gradually to sustainable strategic management frameworks. Nevertheless, to adopt sustainability in business requires concomitantly acquiring financial performance and having access to disposable financial capital. The paper explores the current challenges of sustainable strategic management in parallel with the academic discussions on shareholders’ value creation, investigating the relation with available sustainable investments’ practices. The long-term and short-term financial performance of sustainable business practices are investigated, as well as the orientation of professional investors regarding ESG programs, as presented in recent literature. The authors discuss the importance of knowledge in adopting sustainability in business, the organizational maturity in adopting sustainability in day-to-day activities, as well as the impact of regulatory stimulus and of financial performance on investing in ESG programs. Finally, the paper tackles the necessity to make available more financial resources alongside a gradual transformation of managerial mentalities oriented toward measurable and well-defined planned sustainable strategic management.

Authors: Andrei Ana-Maria
Published: March 2024

The paper discusses the work from home (WFH) phenomenon during the Covid-19 pandemic and aspects related to teamwork performance for the case of companies operating in Romania in knowledge-intensive business services (KIBS). The paper presents the results of an exploratory investigation based on semi-structured in-depth interviews addressing the effects induced by the intensive WFH on teamwork, teamwork performance, and transactive memory systems (TMS) in the investigated KIBS, during the Covid-19 pandemic. The paper is divided into three parts. The first part presents the purpose of the investigation and the context, introducing the concepts and literature. The second part presents the research method and findings. The third part discusses the research results, indicating that the mandatory WFH imposed by the Covid-19 outbreak has disrupted the coordination between teammates, eroding TMS operation and the level of teamwork performance. The paper concludes on the strong link between teamwork performance during the mandatory WFH period and the presence of TMS reflected by specialization, credibility, and coordination within the team.
Some Have Other Crisis Concerns: Antecedents of Anxiety while Grocery Shopping
Authors: Zulauf Katrin , Wagner Ralf
Published: March 2024

This study relates consumer behaviour with social disruption theory by identifying the antecedents of anxiety related to grocery shopping. Our research design integrates cognitive, behavioural, self-identity, emotional components in disruptive situations. This study presents a conceptual framework focusing on the cognitive and behavioural antecedents of anxiety relating to grocery shopping in disruptive situations. The conceptual model was validated by fitting a SEM with the FIMIX-PLS algorithm to 228 responses obtained an online questionnaire in Brazil and Germany. Two distinct segments of consumers— concerned and scared consumers—differing by their perceived vulnerability are identified. Concerned consumers are characterized by a strong relation of personal concerns to anxiety. The empirical contribution roots in the identification of two types of customers with respect to concerns and anxiety: (i) the concerned because of their situational awareness and (ii) those with more pressing problems. Thus, our study contributes to consumer behaviour and social disruption theory by clarifying and quantifying the impact of the antecedents of anxiety related to grocery shopping in crises. The resulting data from survey responses are cross-sectional, which means it cannot provide evidence of temporal sequence. Retailers benefit from actively shaping consumers’ emotional experiences through measures. The perceived consumers’ need for coping strategies to reduce their anxiety (e.g., shopping in less frequented stores) can thereby be eliminated.
The Effects of the Covid-19 Crisis on Romania’s Main Trading Relationships in 2020
Authors: Tudorache Adrian Tudor , Nicolescu Luminița
Published: March 2024

This paper is motivated by the influences that the COVID-19 health crisis had on the economies of the world. The economic crisis that has evolved from the health crisis affected economic life at all levels (global, national, industry, and company levels), including the trading relationships between countries. The purpose of the paper is to analyze the influence of the COVID-19 health crisis on the bilateral trading relationships between Romania and its main trading partners in terms of both exports and imports, for the year 2020. The research method used is multiple regression with exports and imports as dependent variables and the COVID-19 burden (solely the number of COVID-19 cases, solely the number of COVID-19 deaths and both taken together) and GDP in both Romania and the trading partners, as independent variables. The data has been collected from international organizations’ statistical databases. The findings of the paper illustrate that both the GDP of Romania and the COVID-19 burden in both Romania and the partner countries influenced the bilateral trading relationships of Romania with its main trading partners in 2020. Romanian imports were more affected than exports by the COVID-19 burden both from Romania and from the trading partners. The number of deaths due to COVID-19 had a higher influence on trade than the number of COVID-19 cases. Based on this country case study, we can assert that global sanitary crises do have an influence on the international trade relationships of countries. Consequently, specific measures need to be taken by policymakers in order to first ensure economic recovery and second to support and maintain international trade flows during times of strong health crises.

Authors: Şoldan Bianca-Roxana Sălăgeanu , Bejinaru Ruxandra
Published: March 2024

This research paper aims to identify the factors, components, and key aspects that significantly contribute to the establishment of a sustainable business ecosystem through a comprehensive bibliometric analysis. By analysing prominent publications, we seek to describe coherent strategies with an expected impact. Our objectives encompass exploring trends from both theoretical perspectives, such as predictions by scientists, and empirical perspectives, including figures derived from studies. We outline several secondary objectives that guide our step-by-step approach. Firstly, we identify defining elements of a sustainable business environment based on insights from specialized literature. Secondly, we categorize ecosystems into different types, such as economic, digital, ecological, and entrepreneurial, providing further elaboration later in the paper. Thirdly, we present an updated understanding of the dynamic evolution of ecosystems and their components. This includes examining the influence of digital advancements and digitalization on the business environment, as well as the opportunities and threats they generate. Of particular importance is the role of universities as a significant landmark within the business ecosystem. We discuss the university's involvement in technological and informational transfer to ensure sustainability, focusing on the levers through which universities consolidate and stimulate the business ecosystem. To achieve our objectives, we employ bibliometric analysis, utilizing the VOSviewer software, which offers valuable insights for constructing diagnostic schemes and development models tailored to specific business environment challenges. The research methodology relies on the VOSviewer software for processing academic publication databases. To align with the theme and purpose of this study, we selected the SCOPUS database for its implicit certification of superior academic quality in the publications it contains.
The Dynamic Effect of Financial Sector Development in Stimulating the Gross National Savings of Djibouti
Authors: Dirir Sadik Aden , Aden Kadir
Published: March 2024

Savings are important determinants of wealth. At the macroeconomic level, governments attach importance to saving money in order to make new investments, produce new capital goods, and sustain economic growth. However, due to the high level of internal and external debt in Djibouti, it is nearly impossible for the country to achieve domestic savings. Hereby, the major aim of this study is to examine the dynamic effect of financial sector development in stimulating the gross national saving of Djibouti from the period 1987 to 2021. The paper considered numerous indicators as measurements of the financial sector development including FDI inflows, domestic loans to the private sector, central bank assets to GDP, and money supply. To proceed with the analysis, Non-Linear Autoregressive Distributed Lag (NARDL) was performed and according to the model, the findings highlighted that the Djiboutian financial industry is still in its early development and has not yet made a substantial contribution to boosting the country’s national savings. Nevertheless, the gross national saving of Djibouti was still positively prompted by significant components of the financial sector development, such as the positive shocks of FDI inflows and both the negative shocks of central bank assets and money supply. While both the positive and negative shocks of the credit offered to the private sector were uncovered to diminish the national savings in the long run. In conclusion, the current research will help governments and policymakers understand the best ways to use the financial sector to raise gross national savings. It will also present evidence of how to implement long-term initiatives that can lower public debt and encourage savings. Not to mention, the article provides information on the value of long-term investments.

Published: March 2024

The experimental research was carried out to study the tribological behaviour of materials used in the manufacture of rotary dryer blades (based on abrasive/abrasive-erosive wear analysis of the blades) using the Baroid tester. The test program included 2 series of tests consisting of subjecting the specimens to a wear process, generated by friction between their test surface and a rotating granite roller. Each set of tests was by specific parameters characterized: test medium, rotational speed of the granite roller, pressing force of the roller on the specimen surface, test time, number of test cycles. The test results highlight the erosion phenomenon (abrasive erosion) responsible for the damage of the rotary dryer blades and the conditions of accentuation of specific wear phenomena.

Background
TANGO2 depletion was found to cause clinically recognizable multi-organ involvement disorder in pediatrics with episodic muscle weakness recurrent rhabdomyolysis, intellectual disability, metabolic encephalomyopathic crises and cardiac arrhythmia. TANGO2 deficiency is also referred to as \"metabolic encephalomyopathic crises, recurrent, with rhabdomyolysis, cardiac arrhythmias, and neurodegeneration\" (MECRCN) in OMIM. * 616830

Case presentation
We report a case of a 4-year-old Saudi boy from a consanguineous Saudi family with two uncles deceased at 3 year of age with recurrent muscle weakness and hyperammonemia of unknown cause .Patient in last attack progressed to severe metabolic encephalomyopathic crisis that required assisted ventilation for 4 months, complicated with life threatening cardiac tachyarrhythmia. Laboratory findings of hypoglycemia, mild hyperammonemia , severely elevated plasma Creatine Kinase, myoglobinuria , lactic acidosis and increased TSH concentration indicating hypothyroidism have been documented. The clinical profile was highly suggestive of TANGO2-realted disorder. Direct DNA sequence analysis of the entire coding regions of TANGO2 gene identified a novel homozygous deletion for three nucleotides in exon 2 (c.11_13delTCT) resulting in amino acid deletion (phenylalanine) at position 5.

Conclusion
This report illustrates the importance of collating clinical data and keeping a high index of suspicion in order to reach to the diagnosis.

This study was carried out to assess the extent of concentration exposure of As, Cu, Cr, Ni and Mn in the soils of five active dumpsites located at (Eliozu, Oyibo, Eneka, Eleme and Woji) in the city of Port Harcourt Rivers State, Nigeria to evaluate the pollution indices of heavy metals. Soil samples were collected randomly at the quadrant from the dumpsite while control samples were collected from farmland 25 km away from the dumpsite. Some physiochemical parameters (pH, TOC and CEC) of the soils were evaluated using standard techniques, while the heavy metal concentrations were evaluated using Atomic Absorption Spectroscopy (AAS). The pollution levels of soil heavy metals were assessed using several pollution indices. The mean concentration of heavy metals (mg/kg) ranged between As (ND – 0.45), Cr (ND – 2.21), Cu (6.05 – 51.87), Mn (3.24 – 37.91), Ni (ND – 13.50) across the studied dumpsites. The heavy metal levels in soil samples observed were in the order of Cu > Mn > Ni > Cr > As (Eleme), Cu > Mn > As > Ni > Cr (Eliozu), Cu > Mn > Ni > Cr > As (Eneka), Cu > Mn > Cr (Oyigbo), Cu > Mn > Ni > Cr > As (Woji), Cu > Mn > Ni > Cr > As (Control Site). The pH results were relatively acidic across the studied dumpsites ranging from 5.7±0.58 to 6.63± 0.02, while the TOC levels were low to moderate showing no wide disparity in the values. The Cation exchange capacity (CEC) showed a range of 13.98±0.186 (Eneka) to 20.98±0.061 cmol/kg (Woji) across the studied dumpsites. The Igeo values except for Ni, Cu and Mn at Eneka dumpsite, Cr and As in all the studied dumpsites revealed moderate to heavy contamination. Pollution load index (˃ 1) was  in the studied dumpsites which implies that there is heavy metal pollution across the studied dumpsites. Anthropogenicity indicates that human activity is mostly responsible for the increase in metals in the studied area. Low ecological risk indices for the heavy metals (Ni, Cu, Cr, Mn, As) were found in all the sampling locations except for copper in Oyibo dumpsite. According to the findings, there is a low to moderate level of heavy metal pollution in the soils from the dumpsite, which can deteriorate the food ecosystem if adequate measures are not put in place.

Entrepreneurial ability is a key word to create added value from kawung trees in improving the welfare of the farming community with a positive business approach in preserving nature. Kawung trees have long been regarded as a natural resource inheritance, so people have not been serious about developing them, from nurseries to processing and looking after them in the long run. The government is expected to have an important role to play in the survival of these kawung trees in improving the welfare of the community and protecting the environment in the short and long term.Kawung tree (Arrenga pinnata merr) besides having high economic value also functions for nature conservation because it has shallow and wide roots so that it serves to prevent erosion.From the economic side, from leaf buds to roots, they can be utilized and provide economic value, so that the community benefits directly, especially by creating added value from fruit, leaves, palm fibers, roots and trees so that farmers' welfare increases.Improving entrepreneurial skills of Kawung farmers needs to be a priority by developing local wisdom so that nature conservation is maintained. This combination cannot be delayed anymore, because the number of kawung trees is decreasing and landslides and floods have become routine every year in Garut district. West Java Province as the biggest center of production of Kawung and Garut Regency in particular is one of the centers of producing products with basic ingredients Kawung, ranging from broom sticks, palm fibers to a variety of palm sugar products, so that it has been known both locally and internationally.Creation of value added from kawung can be done by building kawung farmers with positive entrepreneurship so that it will improve the welfare of farmers and the preservation of alampun will be maintained. However, from the entrepreneurial abilities of Kawung farmers in Garut district, the creation of kawung added value, as well as the preservation of nature are not fully understood, so kawung trees continue to decrease and landslides and floods always occur every year.

Low back pain (LBP) is a complaint that many people experience throughout our lives. It can occur in young people, but is most often experienced by geriatrics or workers who lift weights. We sometimes treat ourselves by means of a massage, taking over the counter medicine or going to a health facility. Taking medicine without a doctor's prescription and it lasts for a long time can cause damage to the liver, kidneys and stomach. The Covid-19 pandemic in Indonesia since mid-2020 has caused changes in social life challenges. Covid-19 is easily transmitted, through micro-splashes of saliva and can last a long time in contaminated air or objects. Advanced age, history of diabetes, high blood pressure, and heart disease are high risk factors. Currently, many are afraid to go to health facilities because many people gathering for treatment will put patients and health workers at risk of contracting Covid-19 amid the pandemic, so they often seek other treatment that can cause complaints of low back pain to get worse. The aim of this service is to provide knowledge and skills to the community online so that they can independently handle complaints of low back pain amid the Covid-19 pandemic. The solution offered was to conduct a simple hand manipulation webinar to independently treat low back pain complaints. The implementation results showed that most of the participants had complaints of low back pain. After following the demonstration given by the instructor, most of the participants experienced a decrease in the pain scale in the waist. In conclusion, online hand manipulation is a simple, easy to apply, and quite effective technique for dealing with low back pain experienced by participants
La educación y la intención emprendedora en estudiantes universitarios: una revisión en Latinoamérica

América Latina, en las últimas décadas, ha presentado un interés creciente por la actividad emprendedora debido a la importancia de la educación en el desarrollo estudiantil. Se realizó la recopilación de una muestra de trabajos publicados en países de América Latina que implicó la relación entre educación y la iniciativa emprendedora de los estudiantes. Se elaboró la revisión documental con una muestra de 58 documentos de nueve países de la región, donde se exponen las principales conclusiones y se analizan las coincidencias y diferencias entre ellos, para establecer la importancia dada a la educación universitaria en la formación de futuros emprendedores. Del análisis se tiene que, para la mayoría de los investigadores, la universidad cumple un rol preponderante en el desarrollo del espíritu emprendedor. Sin embargo, aún falta que las universidades latinoamericanas internalicen su rol formativo y que además los factores socioeconómicos de los estudiantes también condicionan la finalidad emprendedora en sí.
