Authors: El Shazly Aya , El-Refaee Khalida E. , Abdel Kader Mona A. , ElBagoury Iman , Maghraby Hend M.
Published: March 2024

Background

Interleukin-18 (IL-18), known as a member of IL-1 family cytokines, is found to be elevated as a part of the chronic low-grade inflammatory process in obesity, metabolic syndrome, and type 2 diabetes (T2D). Patients with carotid intima-media thickness (CIMT) exhibited a higher level of IL-18 in the serum.

Objective

To study the relation between serum IL-18 and CIMT in patients with type 2 diabetes mellitus (T2DM).

Patients and methods

A total of 60 patients diagnosed as having T2D and 30 age-matched and sex-matched patients as a control group were recruited in this study. Diabetic patients were divided into two groups according to the presence or absence of diabetic nephropathy. Clinical examination and laboratory investigations including serum IL-18 (by ELISA) and CIMT of both common carotid arteries were carried out.

Results

Mean serum IL-18 level was significantly increased in patients with T2DM when compared with the control group. There was a significant increase in the mean serum IL-18 in patients with diabetic nephropathy compared with those patients without nephropathy. Moreover, there was a significant positive correlation between serum IL-18 and CIMT, glycated hemoglobin, serum lipids, creatinine, urea, and urinary protein in patients with T2DM (group I) (P<0.001).

Conclusion

Serum IL-18 level and CIMT were higher in T2DM than that in controls and in diabetic patients with nephropathy compared with those without nephropathy. Higher serum IL-18 levels correlated with larger CIMT, suggesting a role of IL-18 in atherosclerosis.
Efficacy and safety of intravaginal misoprostol and intracervical foley's catheter ballooning in second trimester pregnancy termination
Authors: Mohammed Naglaa H. , Hakam Faiza A.A.
Published: March 2024

Background

Termination of pregnancy in second trimester is one of the greatest challenges in modern obstetrics practice and is more risky than during first trimester. Now the main concern of the obstetrician is to provide the most effective, safest, and cost-effective regimen with least or no complications.

Objective

To compare the efficacy and safety of intravaginal misoprostol alone and in combination with intracervical Foley's catheter ballooning for termination of pregnancy at second trimester.

Patients and methods

This prospective randomized clinical study was conducted at Alzahra University Hospital and Alglaa Teaching Hospital from June 2019 till June 2020. A total of 100 pregnant women with second trimester who missed abortion were randomly divided into two groups: group I included 50 patients who received misoprostol 200-mg tab intravaginally per 6 h till maximum of four doses, in addition to intracervical Foley's catheter being placed till the catheter got expelled out spontaneously or after 24 h. Group II included 50 patients who received only misoprostol (200 μg) tab, same dose as group I.

Results

In this study, the success of abortion within 24 h was 42 (84%) cases in group I and 29 (58%) cases in group II. The failure of abortion after 48 h was 6% (three cases) in group I and in 18% (nine cases) in group II. The mean induction to abortion time was 14.26 h in group I and 17.243 in group II, with P value of 0.002. There was a significant decrease in the need for surgical evacuation [three (6%) cases − in group I compared with seven (14%) cases in group II]. There is no significant difference between both groups regarding complications (lower abdominal pain, postabortion bleeding, vomiting, headache, and fever); all these complications were mild.

Conclusion

Combined use of intravaginal misoprostol and intracervical Foley's catheter has a shorter induction to abortion time than misoprostol alone and less need for surgical evacuation, with no significant increase in adverse effects.

Authors: Shalabi Hanaa M. , Yosry Lamyaa M. , Mohammad Suzan Z.
Published: March 2024

Background

Tranexamic acid (TXA) is one of the prominent amino acid lysine synthetic derivatives having its antifibrinolytic effect through the reversible blockade of the lysine-binding sites on plasminogen molecules. It is regularly administered intravenously to treat and avoid bleeding, with good results.

Objective

This study was carried out to evaluate the effectiveness, safety, and complications of using TXA in elective cesarean section (CS).

Patients and methods

This was a prospective study that was conducted at Al-Zahraa University Hospital and El Sahel Teaching Hospital on 200 patients planned for elective CS: 100 patients were given 1 g/10 ml TXA (group A) diluted with 20 ml of 5% glucose, whereas another 100 patients received 30 ml of 5% glucose (group B) 10 min before CS. Following the delivery, patients in both groups received a 5 IU intravenous bolus of pre-prepared oxytocin followed by 30 IU oxytocin in 500-ml lactated Ringer's solution, infused at a rate of 125 ml/h. An antibiotic, 1 g cefazolin, was diluted in normal saline of 20 ml, and it was administered over a duration of 5 min. Estimated blood loss was measured by comparing the hematocrit values before and after the procedure.

Results

The study revealed a statistically significant decrease in hemoglobin level in group B (placebo group) compared with group A (TXA group), which indicates that there was a significant reduction in the amount of intraoperative and postoperative blood loss in CS in TXA group.

Conclusion

The use of TXA before CS shows positive effects and can be used as a prophylaxis against postpartum hemorrhage, as revealed by the findings of this study.

Published: March 2024

Background

Total intravenous anesthesia (TIVA) and volatile inhalation anesthesia are both standardized techniques for lumbar laminectomy and discectomy procedures.

Objective

To compare TIVA versus desflurane anesthesia in improving postoperative recovery for patients undergoing spinal fixation.

Patients and methods

This prospective, double-blind, randomized study was carried out on 60 patients undergoing spinal fixation. Patients were randomized into two equal groups: group D received desflurane anesthesia, and group T received TIVA technique. Induction was done by propofol, fentanyl, and rocuronium. Anesthesia was maintained using desflurane in oxygen air mixture in group D. Still, anesthesia was maintained by intravenous infusion of propofol and dexmedetomidine in group T. Intraoperative vital signs, recovery time, postoperative nausea and vomiting, visual analog score, postanesthetic care unit stay time, total first 24 h postoperative analgesic needs, and serum cortisol and interleukin 6 preoperative and postoperative were assessed.

Results

TIVA group had lower intraoperative heart rates and mean arterial blood pressure. TIVA group also had a faster recovery time, shorter postanesthetic care unit stays, lower postoperative visual analog score for pain assessment, lower total analgesic requirements, and lower incidence of nausea and vomiting.

Conclusions

TIVA provided better postoperative recovery with fewer postoperative adverse effects and analgesia need.
Analgesic efficacy of continuous subcutaneous presternal bupivacaine infusion vs ultrasound-guided bilateral pectoral nerve block in poststernotomy pain
Authors: Abdelmaboud Mofeed A.
Published: March 2024

Background

The most common cause of pain after cardiac surgery is median sternotomy. Poor postoperative (PO) pain control has serious effect on pulmonary and cardiovascular systems and induces stress and hyperglycemia. Good PO analgesia helps early recovery and discharge.

Aim

The primary aim was to compare analgesic efficacy of continuous presternal bupivacaine infusion and ultrasound-guided bilateral pectoral nerve 2 block (Pec 2). The secondary aim was to evaluate their efficacy in controlling respiratory parameters, duration of PO ventilation, ICU stay, and hospital stay.

Patients and methods

A total of 100 patients of American Society of Anesthesiologists status II were randomly divided into group I, which received continuous presternal bupivacaine infusion, and group II, which received ultrasound bilateral Pec 2 block. PO visual analog scale (VAS) was recorded at extubation, 3, 6, 12, 18, and 24 h. Pain severity was divided into four grades: no pain, VAS less than 4; mild, VAS 4–5; moderate, VAS 6–7; and severe, VAS greater than 7. Morphine, bupivacaine consumption (mg), and number of request of analgesia in first PO 24 h and inspiratory flow rate (IFR) (l/min) at extubation, 3, 6, 12, 18, and 24 h were recorded. Arterial blood gas parameters were recorded at extubation, 3, 6, 12, and 24 h. Duration of PO ventilation (min), ICU stay (h), and hospital stay (days) were recorded.

Results

PO VAS, pain severity, IFR, and arterial oxygen tension/inspired oxygen fraction (PaO2/FIO2) were significantly higher in group II at all study times. Morphine, bupivacaine consumption, and number of request of analgesia in first PO 24 h were significantly higher in group I. Duration of PO ventilation, ICU stay, and hospital stay were significantly longer in group I.

Conclusion

First, Pec 2 block was safe and effective in controlling sternotomy pain with lower VAS and pain severity, less bupivacaine, morphine consumption, and less request of PO analgesia. Second, Pec 2 block showed better IFR and PaO2/FIO2, with shorter duration of PO ventilation, ICU stay, and hospital stay.

Authors: Liu Rui , Hu Jia-Qi , Zhang Xing , Wu Xiao-Yi , Wei Hua-Min , Zhao Yuan-Chen , He Shu-Lin , Yu Jing , Qi Xin , Pei Ying-Xia , Chen Hong , Li Wei-Dong , Hua Bao-Jin
Published: March 2024

Background:

Shuangshen granules (SSGs) are extensively utilized for the treatment of lung cancer in China and have been reported to possess tumor-protective and anti-metastatic effects. Therefore, it is crucial to understand the precise mechanism. Building upon the findings of our previous study, the objective of the present study was to explore the impact of SSGs on the sphingosine-1-phosphate receptor-1 (S1PR1)/signal transducer and activator of transcription 3 (STAT3) axis, as well as the recruitment of myeloid-derived suppressor cells (MDSCs) during the formation of the premetastatic niches (PMNs).

Methods:

In a mouse xenograft model utilizing Lewis lung carcinoma (LLC) cells that express green fluorescent protein (GFP), the initiation of lung metastasis was monitored every three days until day 35 following transplantation. Lung metastasis, MDSC recruitment, the expression of PMN and S1PR1/STAT3 axis biomarkers, as well as the blood levels of granulocyte-macrophage colony-stimulating factor (GM-CSF) and transforming growth factor-β (TGF-β) were assessed in the SSG treatment and control groups.

Results:

The LLC cells did not reach the lung until 14–17 days following subcutaneous implantation, which was concurrent with the formation of lung PMNs. SSG significantly postponed the initiation of lung metastasis and reduced the recruitment of MDSCs to the lung PMNs. SSG also suppressed the S1PR1/STAT3 axis in tumor tissues, bone marrow, and lung PMNs. Additionally, SSG suppressed the blood levels of GM-CSF and TGF-β, as well as the PMN markers, matrix metalloproteinase-9 and versican.

Conclusion:

Our findings suggested that SSG suppressed the development of MDSC-mediated PMNs by inhibiting the S1PR1/STAT3 axis, consequently postponing the initiation of lung metastasis.

Published: March 2024

The development of digital technology is rising. It creates favorable conditions for the workforce and increases participation in the gig economy. Online jobs are getting more approachable and convenient. For many reasons, there have been differences in generations in the gig economy. Therefore, managers need to have conversation methods and policies to attract workers of each generation to participate in the gig economy. The study has been conducted to identify, analyze, evaluate, and quantify the influence of factors on the intention of different generations to participate in the gig economy. Data was collected from 374 workers of three generations (X, Y, Z) who have not yet participated in the gig economy in Vietnam - an emerging market with both potential opportunities and challenges for managers and investors. The research hypotheses were tested by Partial Least Squares Structural Equation Modeling (PLS-SEM). Results have shown that each generation has different intentions to participate in the gig economy. Factors including perceived risk, current income, skills, flexible working time, and platform, which also differently affect these generations’ intentions. Some managerial implications and future research were suggested.

AN IN VITRO SCREENING TO COMPARE THE ANTI HEAD LICE ACTIVITY OF KSHEERAVIDARYADI TAILA PREPARED WITH NARIKELA TAILA AND KARANJA TAILA
Authors: L Ananya , T Roopini , M Goud Kiran
Published: March 2024

Pediculosis capitis, or head louse infestation, is a longstanding global concern, particularly prevalent in tropical and subtropical regions. Despite not posing a primary health threat, it remains a significant social problem, af-fecting millions worldwide. Existing treatments, including Permethrin, Malathion, and Lindane, often result in side effects such as irritation and swelling. While Ayurvedic texts mention references to head lice and their management, studies have yet to explore these aspects. This study investigates the efficacy of Ksheeravidaryadi Taila, a Taila yoga formulation, for treating head louse infestations. Two formulations, Sample-A (Narikela taila base) and Sample-B (Karanja taila base) were subjected to in-vitro screening, evaluating their effects on head lice movements, irritability, and vital signs over time. Methods: In-vitro screening involved the application of Sample-A and Sample-B on head lice, with comparative assessments against plain Narikela taila, Karanja taila, and distilled water. Observations were made on movements, irritability, and vital signs of the lice. Microscopic studies were conducted to analyze the effects further. Results: Sample B demonstrated a quicker and more po-tent action, inducing irritability and cessation of vital signs in head lice within 45 minutes. Sample A exhibited similar effects, albeit with milder intensity and a prolonged duration. Microscopic studies revealed no crucial signs in either sample, with bleeding observed in Sample B. Conclusion: The study underscores the potential efficacy of Ksheeravidaryadi Taila, particularly Sample B with Karanja taila base, which might be helpful for the treatment of head louse infestations. The formulation's alignment with Ayurvedic principles, including Tikta rasa and Krimihara attributes, coupled with faster drug action and higher saponification values, suggests its effective-ness.

In this paper, we consider the initial-boundary value problem for a class of nonlinear coupled wave equation and Petrovesky system in a bounded domain. The strong damping is nonlinear. First, we prove the existence of global weak solutions by using the energy method combined with Faedo-Galarkin method and the multiplier method. In addition, under suitable conditions on functions gi(⋅), i = 1, 2 and a(⋅), we obtain both exponential and polynomial decay estimates. The method of proofs is direct and based on the energy method combined with the multipliers technique, on some integral inequalities due to Haraux and Komornik.

Published: March 2024

Calotropis procera, a species of family Asclepiadaceae is known in traditional system of medicine from centuries due to its property of curing a number of ailments. It is a xerophytic shrub found in tropical regions of Asia and Africa. It’s flower is useful in anorexia, indigestion and intestinal worm infestation, dysentry, abdominal disorders etc. It is used in many Ayurvedic, Unani and Siddha formulations. Hence investigation on the regional and irrigation-induced variations in secondary metabolites of Calotropis procera flowers across diverse agro-climatic zones in Rajasthan, India, was taken up to find best region for their collection. The study shows that ACZ IIIA has the highest petroleum ether extract content and ACZ V displays elevated methanol extract yields. Within ACZ IB, involving Hanumangarh and Suratgarh, contrasting results in petroleum ether extract and methanol extract yields are observed, with petroleum ether extract higher in the irrigated area and methanol higher in the non-irrigated region. ACZ V demonstrates the maximum total extractive yield, while ACZ IB shows minimum values. Flowers from the irrigated area in Hanumangarh (ACZ IB) exhibit lower values for sterols and alkaloids compared to those from Suratgarh, the non-irrigated region, indicating a complex interplay of environmental factors. The observed variations provide insights into the environmental influences on secondary metabolite content of Calotropis procera flowers, contributing to a deeper understanding from ecological and agricultural perspectives.

Authors:   Ling Tung University, Taichung, Taiwan, Hsiao Ju Chen, Hui-Jing
Published: March 2024

This study investigated the effects of an online peer learning program on undergraduate student English speaking proficiency, language anxiety, and perceptions of online peer learning. The study adopted a case study design and recruited 32 undergraduate students from the Department of Applied Foreign Languages at a university in central Taiwan. The online peer learning program improved students’ English communication skills and reduced students’ learning anxiety by facilitating interactions with online foreign peers. Quantitative data from oral proficiency tests and the Foreign Language Classroom Anxiety Scale were collected before and after the online peer learning program. Qualitative data were analyzed and coded to determine students’ perceptions of the online peer learning program. A significant improvement in the students’ oral proficiency was observed in the pretest and posttest scores. However, no significant reduction in overall speaking anxiety levels was noted, although the students reported a noticeable decrease in anxiety levels following the intervention, particularly when they talked about general or familiar topics. The results of this study demonstrate that the online peer learning program effectively enhanced the speaking proficiency of students of English as a foreign language and moderately alleviated their learning anxiety. On the basis of these findings, this study provides suggestions for foreign language teachers.

An Islamic guideline and instruction that can raise the public health standard is to lead a clean and healthy lifestyle, which must be done based on awareness and will. It takes time and effort to adopt Clean and Healthy Living Behaviours (henceforth PHBS) for everyone as individuals interact and affect one another within their order of living. This research aims to determine the Islamic education approach to promote PHBS in Muslim communities living on the coast in Cirebon, West Java, Indonesia. Additionally, this research seeks to identify factors impacting religious beliefs and adopting these practices. This study employs a descriptive qualitative methodology. The research findings show that an Islamic education approach can be instilled to promote PHBS in coastal Muslim communities. The influence of the Islamic education approach that always appears in the lives of coastal Muslim communities to improve public health: first, significant others (influential people); second, social environment; third, culture; fourth, social structure; and fifth, belief system; sixth, economic conditions; and seventh, Islamic education. The driving factor is the behaviour of Posyandu (Integrated Healthcare Center) cadres, sub-district employees, religious leaders and community health centre officers who are essential. The obstacle factors in fostering PHBS are the availability of rubbish bins and the need for more awareness among the public about disposing of rubbish in its proper place, so they throw rubbish in drainage channels and the sea, and some people burn it. Waste causes air pollution, a social economy, low public education and a low understanding of the value of Islamic teaching.

Published: March 2024

Ethiopia possesses the most important and diversified genepool of Coffea arabica in wild populations, traditional landraces and cultivated varieties. The availability of high genetic diversity is fundamental for any crop improvement program for use by the plant breeders. This study presents economic valuation of Coffea arabica in terms of pest and disease resistance, increased productivity /yield, drought tolerance or climate change resilience, low caffeine content and higher cup quality. The wild Coffea arabica embedded in the natural forest has a wide range of benefits, including cultivated coffee genetic enhancement, provision of ecological services as well as an intrinsic value. This economic assessment estimated the values of Coffea arabica biodiversity in term of coffee genetic enhancement for increased yield, increased pest and disease resistance, low caffeine, high cup quality, drought and climate change resilience, and GHG reduction using indirect market-based of revealed preference techniques. Our assessment revealed enormous potential of Ethiopia’s Arabica coffee biodiversity to improve and sustainably produce coffee globally and in the country. If Ethiopia exploits its coffee genetic resources potential for coffee production in the country, it gets an additional benefit of USD 2.37-5.84 billion per year. Besides, if coffee producing countries use the genetic resources in Ethiopia to solve their coffee production problems, there is a potential economic benefit of USD7.6-8.1 billion per year. If users of these genetic resources are willing to pay 5% of their gain in economic benefit from the accessed Ethiopian coffee genetic resources to Ethiopia, the country can get additional income of about USD380-403 million per year.

Objetivo. Identificar predictores independientes de cirugía de revascularización miocárdica (CRM) en pacientes con síndrome coronario agudo sin elevación del segmento ST (SCASEST) del mundo real. Materiales y métodos. Se realizó un análisis preespecificado de forma individual de pacientes con SCASEST, a partir de dos registros argentinos prospectivos entre 2017 y 2022. Se analizó la diferencia en las características basales entre los pacientes que requirieron CRM y los que no requirieron esta intervención. Luego, se realizó un análisis de regresión logística para determinar predictores independientes en los pacientes que recibieron CRM como método de revascularización. Resultados. Se incluyeron 1848 pacientes con una mediana de edad de 54,8 (rango intercuartílico [RIC]): 53,7-56) años y una fracción de eyección de 42,1% (RIC: 41,2-43,1). Un total de 233 pacientes requirieron CRM (12,6%). Las características basales entre ambos grupos fueron similares, excepto en los pacientes que requirieron CRM, que mostraron ser más jóvenes (51,5 vs. 55,7 años; p=0,010), más frecuentemente diabéticos (38,2% vs. 25,7%; p=0,001) y hombres (90,1% vs. 73,7%; p=0,001); además, presentaron en menor medida, una cirugía cardíaca previa (2,1% vs. 11,2%; p=0,011). Luego del análisis multivariable, se asociaron de forma independiente con la CRM: la edad (Odds Ratio [OR]: 0,99, intervalo de confianza [IC] al 95%: 0,98-0,99; p=0,008), sexo masculino (OR: 3,08, IC 95%: 1,87-5,1; p=0,001), antecedente de CRM previa (OR: 0,14, IC 95%: 0,05-0,30; p=0,001) y diabetes (OR: 1,84, IC 95%: 1,31- 2,57; p=0,001). Conclusiones. En este análisis de dos registros de SCASEST, la edad más joven, el sexo masculino, el diagnóstico de diabetes y la ausencia de cirugía previa, fueron predictores independientes del requerimiento de CRM durante la internación.

Reported Speech or Indirect Speech is widely used in the formal register of the language, as at the level of professional communication collocutors are more likely to be interested in sending or respectively receiving the message that a certain job or task has been done instead of emphasising who the author or the performer is. Languages for Specific Purposes (LSP), as professional communication devices, witness multiple instances of Indirect speech communication, hence the need of having such structures much discussed and often practised with our students in economics and with the students in law, during their language classes. A facility thoroughly implemented and largely used with all categories of students in our higher education institution in the time of the recent pandemic, namely the Moodle platform, brings about the online testing tool. This provides the possibility of numerous, accurate, quick self-evaluation tests that can be performed not only at class during the practical courses but also, if such set, at any time the teachers consider proper and allow it, due to the availability of this e-learning platform to all our students, with private accounts, wherever they have internet and a valid device to access it properly. The language teachers can employ this facility creating short tests that would quickly assess knowledge of language, acquisition of grammar aspects and ability to make good use of the structures belonging to the reported speech. With the instant feedback provided by the application, self-evaluations and improvement of knowledge by repeated self-evaluations become available and much valuable tools for hundreds of students, with no more need of corrections from the teachers, a time-saving and very useful learning and testing facility. This paper puts forward some examples of such tests, created by the authors and used during their classes or set for their students’ individual practice. The examples given can be of help to other language instructors who have the possibility to use Moodle or a similar application and are willing to provide their learners with a modern tool of learning and testing, much appreciated by the students as well.

Sustainable economic development, the sustainable competitiveness of countries, is one of the most researched economic issues of our time. This is not surprising, given the years of successive crises. Countries must continue to emerge from these crises without continuing to put pressure on the natural environment that underpins our existence. The spread of consumerism brings with it many environmental problems. The latter is borne out by the emissions of petrol and diesel vehicles. In order to reduce air pollution, the marketing and use of electric vehicles has become increasingly popular worldwide, including in Europe. But what about developing countries or countries with economies in transition? The present work is the introductory part of a larger research project, in which a document analysis based on secondary research was carried out by studying documents, laws and regulations. We sought to find out what factors, including governmental factors, have led to an increase in the number of electric vehicles placed on the market. Several countries were examined, grouped by economic development. We found that the level of economic development of countries influences the amount and extent of incentives introduced. To confirm this, a correlation calculation was carried out, which was not confirmed. However, it can be seen that the myriad of infrastructure, food, epidemiological and overpopulation problems that plague the economies of developing countries mean that local governments have less attention and financial resources to devote to pollution problems. We believe that our study and its continuation can be useful for all those who are interested in electric cars in any form.

Pollution is a problem that humanity faces more and more frequently. Every day we generate increasing amounts of waste and consume more and more exhaustible resources. In this sense, recycling can be considered the response of consumers to the appearance of pollution, being a mediatized concept in the public space. Both through these sources and through the lens of companies, the concept of “recycling” is brought to the attention of consumers. Starting from these considerations, this research aims to identify the best ways to motivate people, as well as analyze recycling behaviour in case of offering a reward. Thus, the research questions are “Do rewards motivate consumers to recycle?” “Do consumers only recycle in the presence of incentives for recycling?” To provide answers to these questions, we started a research together with the retailer Profi Romania. Thus, as part of a pilot project, SGR machines were installed that allow the recycling of plastic packaging and aluminum cans, with customers receiving a reward in the form of a voucher for the recycled packaging. The data provided by the retailer include information on the number of recycled packaging, its type, and weight, as well as the number of vouchers issued and their value. In this case, it was possible to observe the recycling behaviour of consumers under the conditions of offering vouchers, respectively how this behaviour evolves in the absence of incentives for recycling. Most of the studies carried out and presented in the literature analyze aspects related to the importance of recycling, the pillars on which it is based, respectively the types of materials that we should recycle, and under what conditions. The element of novelty that this research brings to the specialized literature is represented by the consideration of motivations (intrinsic, but also extrinsic), considering the recycling behaviour of consumers as a consequence of the motivations that the customer experiences. The results obtained can be generalized for the Fast-moving consumer goods (FMCG) field, the information showing interest for the entire retail field.

The rapid advancement of technology and the Internet led to an unprecedented abundance of information and data. Where too much information exists, the risk raises for that information to become irrelevant or too hard to handle; a phenomenon called information overload. Filtering vasts amounts of data and highlighting relevant information became a priority, especially for ecommerce business. Recommender Systems (RS) as a branch of Decision Support Systems were developed and implemented to help users handle information overload and access items based on relevancy. The financial returns RS have brought stimulated the spread of such referral systems to other business domains. As knowledge is a critical resource in nowadays economy, efficient knowledge production and management are a prerequisite for competitive advantage. E-businesses are concerned with online traffic on their platforms and with customer experience and impressions. The multitude of e-businesses facilitated by the Internet has created a highly competitive market in terms of gaining customers loyalty. New available frontier technologies might help online retailers enhance their customer pool and build a solid relationship with their existing ones. One major issue RS tackle is the information overload, meaning that vasts amounts of data might confuse the customer in making a purchase choice, paradoxically due to too many options. Information overload might lead to fatigue, purchase postpone and overall loss for the online retailers. RS have the power to gather data and transform it to valuable personalized knowledge; a feature that can add more revenue, build customer trust, build a personalized customer relationship and even influence the distribution value chain. In this paper we propose a theoretical overview on the RS and how they create value, their fields of implementation and how they are working. By doing so, we enhance both the RS and the e-commerce literature by analyzing tools and means of economic development provided by the DT.

The article focuses on several relevant directions for what the profile of the cultural institutions manager in the Romanian public domain represents, accentuating a specific type of public institution, meaning, the students’ houses of culture. The questionnaire was the method used to obtain the data concerning the manager’s activity and his role within the Romanian public cultural institution. The research survey consisted of a questionnaire made up of five questions, which was sent to all the managers of the cultural houses of the students in Romania and to some other managers of cultural institutions (theaters, museums, libraries, cultural departments). The answers received were summarized and ranked according to the most important areas of interest regarding management and the institutional role assumed by the cultural manager. The results of the questionnaires showed that the role of manager of a state cultural institution in Romania is challenging and full of contradictions and dilemmas. All respondents agreed that being a manager in a cultural institution requires knowing very well the target group(s) or the beneficiaries of the organized activities and having the necessary vision to satisfy exactly those cultural needs that they require. The main problem is that the human and material resources to satisfy these needs are often limited, so the manager is the one who must make correct and firm decisions regarding the distribution of these resources so that the proposed objectives turn into the expected results. Mainly, the measures for change and a productive management are: facilitating the attraction of income (own, subsidies, other types of financing) for the development of the activity of the students’ culture houses, including on the part of investments in the existing cultural heritage; increasing the number of employees, as well as their appropriate motivation in terms of salary (and/or other benefits); the creation of effective levers for closer collaboration between similar institutions in Romania; promoting the institution through professional marketing means; continuous adaptation of the institution’s actions to the current needs of students.

The current research reports on a pilot study that was conducted to test the feasibility of a larger study exploring a leadership development program at a small and medium-sized enterprise (SME) in the ICT (Infocommunications) sector in Hungary. The study employed a mixed-methods approach to data collection, which included literature review, document analysis, and structured interviews with various participants involved in the leadership development program. The literature review focused on the history, current state, existing gaps and limitations, and theoretical frameworks and concepts related to the research topic. The document analysis aimed to gain an in-depth understanding of the research topic and complement the findings from the literature review. The structured interviews were designed to be consistent and standardized, with a pre-determined set of questions asked to each participant. The interviews were conducted with a diverse group of participants, including the CEO, People Development Manager, Hiring managers, Domain Engineering Leads, the Human Resources team, and participants of the leadership development program. The current research is a smaller-scale version of a full-scale study (also called a “feasibility” study), as well as the pre-testing of a particular research instrument, in our case, document analysis and interview schedule. Pilot researches are a crucial element of a good study design, as it does not guarantee success in the main study, but it does increase the likelihood of success. (Polit et al., 2001, Teijlingen et al., 2001) The paper also discusses the importance of leadership in the ICT sector, citing a survey of Society for Information Management members that identified leadership as the most important soft skill for employees in the sector. The article notes that understanding the preferences of different generations at the workplace is essential to create an effective leadership development program. Out of the total number of employees, 52 currently work in the company’s software development division, and the preferences and motivations of these employees will be a critical factor in designing a successful program. The paper concludes by stressing the importance of pilot studies in research and how they increase the likelihood of success in the main study. The study’s authors hope that the results of this pilot study will provide insight into the characteristics of a leadership development program and assist in developing a more extensive study on the topic.
