Published: June 2022

Background: Glucocorticoids (GCs) are considered drugs of choice for treating nasal polyps (NPs). However, a subset of patients shows a limited clinical response even to high doses of GCs. Altered expression of glucocorticoid receptors (GRs), namely GR-alpha; and GR-beta;, is a potential mechanism underlying GC insensitivity. GCs modulate the expression of several cytokines, including transforming growth factor-beta (TGF-beta), which may contribute to cellular proliferation in NPs. The study investigates some biomolecular features of GC-resistant NPs, and examines possible differences from normal mucosa (NM). Methodology: Radioligand binding assay (binding) was used to determine GR-alpha; binding capacity; Western blotting was used to evaluate GR-alpha;, GR-beta;, and TGF-beta; expression and GR-alpha; subcellular distribution. NPs were sampled in 32 patients during ethmoidectomy; NM was taken from 15 healthy patients during rhinoplasty. Results: GR-alpha; was present in NPs and NM, with lower affinity for the ligand in NPs. GR-alpha; was prevalent in the cytosol of NPs that were GR-alpha-negative to the binding assay. GR-beta was expressed in NPs and absent in the majority of NM. TGF-beta1 expression was higher in NPs than in NM. Conclusions: GR-beta and TGF-beta1 might be involved in NP pathogenesis, but their role in modulating GC sensitivity is still unclear.

Published: June 2022

The cell walls of plants are made up of cellulose as the major composite and the hydrolysis of this polysaccharide has proven to be a major step in the extraction of many biomolecules. This research was on both pure and partially purified endo-1,4-D-glucanohydrolase, EC 3.2.1.4 (cellulase) assisted extraction of essential oil from the seed kernels of Nutmeg by using a two-step protocol that involved the pretreatment of the sample with cellulase followed by the distillation of the essential oil using Clevenger apparatus.  The essential oil obtained after pretreatment with pure cellulase was 8.2 % while 5.8 % of essential oil was obtained when treatment prior to hydro-distillation of oil was done with partially purified cellulase. An oil yield of 3.8 % was observed when no enzyme pretreatment was carried out. The GC-MS analysis of the essential oil obtained from the two-step protocol showed the presence of 25 and 24 components from the sample pretreated with the partially purified cellulase and pure cellulase respectively.  There were three major groups of components observed from the essential oils. These are the monoterpenes made up of sabinene, α-pinene, and β-pinene; the sesquiterpenes made up of safrole and alpha-copaene; and the phenylpropanoid/aromatic compounds, composed of myristicin and methyl eugenol. The presence of these principal compounds in the major groups has given nutmeg essential oil improved value due to the possibility of incorporating them as functional ingredients in several products with possible applications in the pharmaceutical, agricultural, fragrance, flavour, and cosmetic industries

Purpose: To determine the cytotoxic, bronchorelaxant, spasmolytic, antidiabetic, α-glucosidase, acetylcholinesterase, butyrylcholinesterase, α-chymotrypsin and lipoxygenase inhibitory attributes of methanol and dichloromethane extracts of the aerial parts of Breynia distachia.Methods: The dichloromethane and methanol extracts of the aerial parts of the plant were prepared by maceration. Various ex vivo assays were employed, such as the brine shrimp lethality assay, lipoxygenase inhibitory activity assay, α-glucosidase inhibitory assay and α-chymotrypsin assay, as well as assays to assess the spasmolytic and bronchorelaxant activity. Meanwhile, the hypoglycaemic effect were analysed using an alloxan-induced diabetic model in Wistar albino rats.Results: The methanol extract (aerial) showed significant (p ≤ 0.05) cytotoxicity towards brine shrimp larvae at concentrations of 10, 100 and 1,000 μg/mL, respectively, whereas the dichloromethane extract (aerial) of the plant showed non-significant (p ≥ 0.05) results. The methanol extract (aerial parts) also demonstrated significant (p ≤ 0.05) α-glucosidase inhibitory activity and lipoxygenase inhibitory activity, with IC50 (half-maximal inhibitory concentration) values of 40.37 ± 5.29 μg/mL and 132.9 ± 0.33 μg/mL, respectively, while the dichloromethane extract exhibited significant (p ≤ 0.05) α-glucosidase inhibitory activity, with an IC50 value of 135.43 ± 8.29 μg/mL. An in vivo antidiabetic model showed that the administration of 150 and 300 mg/kg methanol extract of the aerial parts significantly (p ≤ 0.05) lowered the blood glucose level in alloxan-induced diabetic rats compared to control (treated with water).Conclusion: Data from different in vitro and in vivo models suggest that the methanol extract (aerial parts) of B. distachia shows significant cytotoxic, bronchorelaxant, spasmolytic, antidiabetic and anti-Alzheimer’s activity Hence, these findings validate the folkloric use of B. distachia and highlight the need to further explore its medicinal potential and the phytoconstituents responsible for its pharmacological actions.

Published: June 2022

Purpose: To study the inhibitory influence of buddleoside on TLR4-associated pathway, autophagy and inflammation in a mouse model of acute liver failure (ALF).Methods: Sixty male C57BL/6 mice were assigned to 5 groups: control, model, and three dose-groups of buddleoside, with 12 mice per group. Levels of interleukin (IL)-1, IL-6, TLR4 pathway-associated proteins, and autophagy-related proteins in each group were determined; cell adhesion in each group was also analyzed.Results: Levels of TLR4, MAPK and NF-кB-related pathways in model mice were significantly upregulated, relative to control mice, but they were more down-regulated in the 3 anthocyanin groups than in model group (p < 0.05). There were significantly higher levels of TNF-α, IL- and IL-6 in model mice than in the control group, but they were down-regulated in high-, medium- and low-dose mice, relative to model mice. The population of adherent cells was significantly higher in ALF mice than in controls, butthere were markedly lower numbers of these cells in the 3 anthocyanin-treated mice than in model mice (p < 0.05).Conclusion: Buddleoside mitigates ALF in mice by down-regulating inflammatory factors, reducing serum levels of ALT and AST, and up-regulating autophagy-related protein expressions by activating TLR4/MAPK/NF-кB signaling pathway. Thus, buddleoside may be useful in the treatment of acute liver failure, but this has to be curtained through clinical trials.

Egon Erwin Kisch znowu górą. Wstęp do rozważań nad reportażem postmodernistycznym
Authors: Wolny-Zmorzyński Kazimierz
Published: June 2022

W prezentowanym artykule zastosowano metodę opisowo-historyczną. Celem artykułu jest wykazanie, że Egon Erwin Kisch to prekursor postmodernistycznych idei stosowanych w reportażu. Kisch po latach od debiutu reporterskiego (1906) jako pierwszy oficjalnie nie krył tego, że wprowadzał fikcję do uprawianego przez siebie gatunku i w swej książce pt. „Jarmark sensacji” (1942) się do tego przyznał. Kisch, aby osiągnąć sukces, zastosował w reportażu metodę zmyślania faktów i wywoływania sensacji w celu przyciągnięcia uwagi odbiorcy. To także ulubiony sposób mówienia o rzeczywistości, szczególnie przez współczesnych reporterów, piszących w stylu gonzo. Kisch pisał z werwą, fantazją, pokazywał m.in. świat nizin społecznych, ich mniej przyjazną stronę. Niniejszy artykuł jest pierwszą w literaturze o Egonie Erwinie Kischu próbą wskazania na autora „Jarmarku sensacji” jako pioniera stylu gonzo.

Egon Erwin Kisch is on top again. Introduction to considerations on postmodern reportage

In the submitted article, the descriptive-historical method was used. The aim of the article is to recognize Erwin Egon Kisch as a precursor of postmodern ideas in reportage. Years after his journalistic debut (1906), Kisch was the first not to officially hide the fact that he introduced fiction to the genre he cultivated and in his book “The Sensational Fair” (1942) he admitted it. To achieve success, Kisch used sensational reporting in order to attract the viewer’s attention. It is also a very popular way of dicussing the reality by modern gonzo-style reporters. Kisch wrote with verve and fantasy. He showed the world of social lowlands, their less friendly side. This article is the first attempt in the literature on Egon Erwin Kisch to point to the gonzo-style of reporting.
Znaczenie wyroku z 5 czerwca 2018 r. w sprawie Coman i inni p. Rumunii, C-673/16, dla linii orzeczniczej Trybunał Sprawiedliwości Unii Europejskiej w zakresie praw osób w związkach jednopłciowych

The importance of the judgment of June 5, 2018 in Coman and Others v Romania, C-673/16 for the jurisprudence of the Court of Justice of the European Union on the rights of persons in same-sex relationships

The Court of Justice of the European Union is gradually expanding its jurisdiction at the expense of the competences of the Member States of EU. However, some of them oppose this, since they perceive it as the CJEU interfering with their authority. Nonetheless, even in matters of their exclusive competence, member states are obliged to adhere to a pro-EU interpretation of their domestic law. The judgment of the CJEU in the Coman case is an example of that – although the case indirectly con-cerns the regulation of civil status, which is the competence of national authorities, Member States must also apply EU juris-prudence when creating and implementing the law in that regard. The article also points to several possible risks discussed in the doctrine which are connected with the Coman judgment, such as reverse discrimination or the risk of a slippery slope. The author identified the role of the judgment and its importance for the jurisprudence on the rights of persons in same-sex relationships.

Published: June 2022

This study used polysaccharide (PS) from yeast cell walls to encapsulate polyphenols (PP) extracted from green tea (a good antioxidant substance) to avoid the effects of sensitive factors such as temperature, light and oxygen, and to preserve its stability and bioactivities. The objective of this study was to investigate the effects of four types of wall material (PS-MD (maltodextrin), PS-whey, whey, and MD). After selecting the most appropriate wall material, the study continued to investigate the effects of the ratios of the core to the wall material (1:1, 1:2, 1:3 and 1:4, w/w); the inlet air temperatures of spray-drying (130, 140, 150 and 160 °C); and the feed flow rates (04, 05, 06 and 07mL/min) on the microencapsulation yield (MEY) and the microencapsulation efficiency (MEE). The results showed the best settings as follows the wall material being PS-MD, the ratio of PP to the wall material as 1:3 (w/w), the inlet air temperatures at 140 °C, and the feed flow rate at 05mL/min. Under those conditions, the MEY and the MEE were found to be highest as 31.118mg/g and 86.73%, respectively. When examined by scanning electron microscopy (SEM), they had various sizes and spherical shapes and some of them had smooth or concave surfaces. As a result, it could be concluded that polyphenols were successfully encapsulated in the PS-MD matrix by spray-drying and the application to some food products could be further studied.
A review of Khmer word segmentation and part-of-speech tagging and an experimental study using bidirectional long short-term memory
Authors: Sry Sreyteav , Nguyen Amrudee Sukpan
Published: June 2022

Large contiguous blocks of unsegmented Khmer words can cause major problems for natural language processing applications such as machine translation, speech synthesis, information extraction, etc. Thus, word segmentation and part-of- speech tagging are two important prior tasks. Since the Khmer language does not always use explicit separators to split words, the definition of words is not a natural concept. Hence, tokenization and part-of-speech tagging of these languages are inseparable because the definition and principle of one task unavoidably affect the other. In this study, different approaches using in Khmer word segmentation and part-of-speech are reviewed and experimental study using a single long short-term memory network is described. Dataset from Asia Language Treebank is used to train and test the model. The preliminary experimental model achieved 95% accuracy rate. However, more testing to evaluate the model and compare it with different models is needed to conduct to select the more higher accuracy model.

Gelatine is a soluble protein derived from animal skin, white connective tissue, or bones via collagen hydrolysis. This project began with CATIA modelling adaptation and progressed through ANSYS Workbench computational analysis processes. The two hyperelastic models (Mooney-Rivlin and Yeoh) were contrasted computationally with assess the distinction in chart execution and other mechanical properties that ought to be corresponding to the exploratory information. The material went through three stages: pre-processing, static structural, and post-processing. Through this computational analysis, the best data execution was presented with the optimum stress and stretch according to hyperelastic constitutive models. The nodes distance expanded was determined by the total deformation plot in addition to the simulation. In comparison to the experimental approach, the Yeoh model yields the lowest percentage error. As a result, when the skin patch can stretch and maintain the condition when force is applied to it, this product has potential to contribute in medical needs.

COVID-19 appeared in Wuhan (China) and spread rapidly to many places, generating a worldwide emergency, and causing concern throughout the health system due to its rapid transmission of contagion, leading to a confinement of all people. During the confinement, the lifestyle and eating habits of many people changed, potentially causing diabetes in themselves. This disease occurs when there is a high level of glucose in the blood and this can generate serious problems for the person, as there is no cure for diabetes, it is necessary for patients to control their glucose level, but for this purpose conventional glucometer equipment is used, which generates pain in patients as they introduce a needle into the finger and extract blood to measure glucose. In view of this problem, this article will develop a glucose meter system that does not require introducing a needle into the patient's finger since it will use the photoplestimographic signal generated by the oximetry sensor and can be monitored, so that the system performs the measurement without pain and shows the value of the glucose level accurately, being of immense help to diabetic patients who need to control their glucose several times a day. Through the development of the system, it was observed that the system works in the best way, when comparing the glucose level measurement with other conventional glucometer equipment, a relative error of 4.786% was obtained, being an accepted error because it is close to the real value of the glucose level in the blood.

One critical concern in designing a cryptographic algorithm is its randomness. The randomness test examines the quality of random numbers generated by cryptographic algorithms. In this paper, the National Institute of Standards and Technology (NIST) Statistical Test Suite for Random and Pseudorandom Number Generators for Cryptographic Applications was instrumental in assessing the security of the modified Playfair algorithm with the novel Multidimensional Element-in-Grid Sequencer (MEGS). Moreover, this study determines the level of security of the MEGS-based Playfair algorithm against brute force attacks. Simulation results revealed that the modified cryptographic algorithm could execute the encryption process with randomly generated ciphertext despite having repetitive letters in the plaintext, as evident in the frequency (monobit) test, frequency within a block test, and runs test with p-values > 0.01. Further, the MEGS-based Playfair algorithm was highly resistant against attacks based on the results of the entropy test and the brute force attack analysis. Since the character keyspace of the modified algorithm is 256, attempts to break the ciphertext would cost a large amount of financial and computational resources. The use of a 16x16 dynamic matrix with matrix rotation, matrix shifting, matrix rolling, and crossover operations enhanced the performance of the Playfair algorithm, improving its resilience to attacks.

Click and mortar or indirect distribution management refers to an omni-channel eCommerce business model that integrates online and offline operations, whereas traditional brick and mortar or direct distribution management refers to a traditional street-side business that offers products and services to its customers face-to-face in an office or store that the business owns or rents. Customers can shop over the internet on the retailer’s website, and still be able to shop at the retailer’s brick and mortar shop. This study determined the status of distribution management of selected retail stores in Metro Manila based on the value chain model of Michael Porter, along with the challenges encountered and the identification of strengths and weaknesses. Utilizing the descriptive comparative evaluative research design, data revealed that the respondents’ assessment on the activities in the distribution management that fundamental phases of activities are evident and observed. The verbal interpretation of observed on the inbound logistics, operations, outbound logistics, marketing and sales, and services has a verbal interpretation of 3.48 and 3.54 for brick and mortar or direct distribution management and click and mortar or indirect distribution management, respectively. Direct traditional respondents and indirect contemporary respondents, on the other hand, rate general administration/firm infrastructure, human resource management, technology development, and procurement as moderately observed, with a mean of 3.27 and 3.31, respectively. Using regression analysis, the model revealed that outbound logistic, marketing and sales, procurement and inbound logistics have positive effect on the competitive advantage for brick and mortar while outbound logistics, marketing and sales, services, procurement and technology development have positive effect on the competitive advantage for click and mortar. It is also revealed that the enhanced value chain model is contextual and significantly fir to the business management needs of the respondents. It is recommended that store management can be implemented to the traditional and modern in doing their business. Moreover, a thorough review and search of location accessibility must be performed in implementing the enhance value chain model.

The data was also used to predict operational performance efficiency of these banking sectors after extracting through machine learning (ML) algorithm models and statistical interpretation of prediction accuracy by using WEKA tool. We used different models viz. NaiveBayes (NB), BayesNet (BN), logistic regression (LgR), Sequential minimal optimization of Support Vector Machine regression (SMOreg), Linear Logistic Regression (SL), Classification via Regression (CR), LogitBoost (LB); Logistic Model Tree (LMT), Random Forest & Random tree (RF & RT), Pruned & unpruned decision tree C4 (J48), and Class implementing minimal cost-complexity pruning (Cart) related to 15 attributes viz. GNPA, NNPA, GDP, CPI, PSL, TL, STA, GDP-1, RR, CPI-1, TE, TP and USTA as numeric as well as Banks, Year, GNPA>6, and GNPA>7, as nominal categories of dataset where overall performance accuracy was determined. The algorithm model classification predicted the highest values were for LB (78.47%) and Cart (74.30%) followed by J48 (73.61%), CR (72.91%) and LMT (69.44%) and lowest value in SMO (34.72%) as per 10-fold cross validation test. Additionally, these predicted results may have valuable implications for Indian banking sectors. We evaluated the operational efficiency as cumulative performance for 12 banking sectors as per assumed cut off values of GNPA. It may be varied with other independent variables like credit risk parameters, etc. It is suggested in future to study with parameters of deposit collection and investment to determine credit risk of these banking sectors.

In the industrial sector, an electrohydraulic actuator (EHA) system is a common technology. This system is often used in applications that demand high force, such as the steel, automotive, and aerospace industries. Furthermore, since most mechanical actuators' performance changes with time, it is considerably more difficult to assure its robustness over time. Therefore, this paper proposed a robust fuzzy sliding mode proportional derivative (FSMCPD) controller. The sliding mode controller (SMC) is accomplished by utilizing the exponential law and the Lyapunov theorem to ensure closed loop stability. By replacing the fuzzy logic control (FLC) function over the signum function, the chattering in the SMC controller has been considerably reduced. By using the sum of absolute errors as the objective function, particle swarm optimization (PSO) was used to optimize the controller parameter gain. The experiment results for trajectory tracking and the robustness test were compared with the sliding mode proportional derivative (SMCPD) controller to demonstrate the performance of the FSMCPD controller. According to the findings of the thorough study, the FSMCPD controller outperforms the SMCPD controller in terms of mean square error (MSE) and robustness index (RI). Keywords—tracking control, electrohydraulic actuator (EHA), robust control design, fuzzy sliding mode proportional derivative (FSMCPD), particle swarm optimization (PSO).

—Noninvasive estimation of blood glucose using microwave based sensor is one of the most challenging research fields in recent days. These methods are more adaptable to avoid soreness and skin estrangement that occur in traditional invasive blood glucose measurement techniques. This paper suggests the investigational outcomes of a microwave based noninvasive blood glucose meter to check performance of the microwave antenna sensor. Narrowband micro strip antenna with resonating microwave frequency of 1.3 GHz is utilized to measure Blood Glucose Level (BGL) noninvasively. Validity of sensor is assessed by performing medical tests on non diabetic and diabetic human volunteers. Mean Absolute Relative Difference (MARD) and Surveillance Error Grid (SEG) analyses were performed during experimentation to find deviation of estimated BGL from reference BGL which is measured using available invasive technique. Direct assessment of estimated data with reference data provides excellent reliability and repeatability of proposed microwave technique. Keywords- glucometer, Blood Glucose Level (BGL), medical tests, Mean Absolute Relative Difference (MARD), Surveillance Error Grid (SEG)

The study of equivalent noise level (Leq), noise parameters, and various noise indices have enabled the evaluation of the overall traffic noise environment of the city. The noise indices such as traffic noise index (TNI), noise climate (NC), traffic noise pollution level (LNP), noise exposure index (NEI) along with day time (LD), night time (LN) average, and day-night (Ldn) noise levels were assessed for the selected traffic junctions. Moreover, spatial noise mapping was carried out using the geostatistical interpolation technique to evaluate the changes of traffic noise scenarios during the different time zones of the day. The Leq values in a few traffic junctions exceeded the required noise standards. The study shows equivalent noise levels ranging between 52.2-69.9 dB(A) during the morning (7-10 am), 52.4 -69.3 dB(A) during noon (12 noon-2 pm), and 54.6-71.1 dB(A) during the evening (4-7 pm) hours, respectively.

Published: June 2022

Scholars have turned their attention to the ecological protection and high-quality development of China’s Yellow River Basin in recent years. The basin is a major agricultural production area in China, hence investigating agricultural carbon emission reduction strategies in the basin is crucial. The research object in this article is the agricultural departmen.ts of China’s nine provinces in the Yellow River Basin from 2005 to 2018. Agricultural carbon emissions are measured using agricultural land usage, rice planting, crop planting, straw burning, and livestock breeding as agricultural carbon sources. In addition, the GTWR model is used to examine the spatiotemporal aspects of the impact of five factors on agricultural carbon emissions in this paper. The findings reveal that the five factors have varying degrees and directions of influence.

In this paper, we study the umbral operators J, M and N associated with the generalized rencontres polynomials D(m) n (x). We obtain their representations in terms of the differential operator Dx and the shift operator E. Then, by using these representations, we obtain some combinatorial and differential identities for the generalized rencontres polynomials. Finally, we extend these results to some related polynomials and, in particular, to the generalized permutation polynomials P(m)n (x) and the generalized arrangement polynomials A(m)n (x).

It is indisputable that technical advancements have an impact on a country's military capability and security. This is inextricably linked to the deployment of numerous technologies and new discoveries aimed at boosting the military's defense system. As a result of this predicament, all governments are attempting to modernize their defense systems in order to deal with dangers posed by technological advancements. This is both a challenge and an opportunity for Indonesia's existing defense system. The goal of this study is to look into the development of cyber weapons and how they may help Indonesia improve its cyber security. The purpose of this study is to utilize a descriptive qualitative technique to investigate or explain the concerns surrounding the importance of cyber weapons in strengthening cyber security in Indonesia. The conclusions of this study show that as the number of Internet users grows, so does the global trend of cyber attacks. It's difficult to compare precision cyberweapons systems to existing kinetic weapons because of their new nature. Additionally, the development and use of cyber weapons can yield economic rewards. Human resources, as well as support and cooperation from Indonesian cyber defense groups with professionals in the field of hacking, are all crucial variables to consider while designing cyber weapons.
Imaginarios de nación en la producción audiovisual oficial e independiente de Paraguay durante la dictadura stronista (1968-1979)
Authors: Zaracho Robertti María Esther
Published: June 2022

Este estudio se propone describir los imaginarios de nación durante el stronismo en un corpus fílmico representativo de la producción audiovisual oficial e independiente de Paraguay de 1968 – 1979 a partir de una revisión del periodo correspondiente a la dictadura de Alfredo Stroessner (1954- 1989) dentro de un contexto amplio a nivel regional y global, los “largos sesentas”. La metodología corresponde a un enfoque etnográfico y se recurre a una serie de dispositivos como la observación participante, entrevistas semiestructuradas, descripción, análisis simbólico e interpretación de contexto de contenido audiovisual, análisis de fuentes bibliográficas, hemerográficas y audiovisuales. Se concluye que durante dicho periodo quedó configurado un campo de disputa entre el imaginario de nación del régimen, representado por el audiovisual oficial y otros imaginarios opuestos y alternos, propuestos desde la producción audiovisual de un incipiente cine independiente.
¿En quién piensa el soldado?
Authors: Jones Aldo
Published: June 2022

La imagen del soldado paraguayo como guerrero valiente ha sido incontestable, no obstante no ha recibido la debida atención desde la historiografía. Por otra parte, los poetas han prodigado versos en su honor y lo han descrito en una dimensión más terrenal. El trabajo aquí presentado es, precisamente, un intento de conocer a este actor histórico a partir del imaginario colectivo recogido de los versos del cancionero popular (y no tan popular) paraguayo, versos que se volvieron canciones con menor o mayor éxito de popularidad en diferentes momentos de la historia.

Published: June 2022

The extant literature showed that the relationship between advertising and the performance of small and medium enterprises (SMEs) is widely researched. However, there is a paucity of literature on the effect of different facets of advertising, as well as moderators on the performance of SMEs. Also, there is a paucity of research of this nature in the context of emerging economies like Nigeria. Therefore, the current research intends to fill this gap and investigate the relationship between four (4) different facets of advertising (traditional advertising, advertising cost, advertising quality, and internet adverting) and the performance of small business enterprises in Katsina, Nigeria. In establishing a relationship among variables, the study adopts a quantitative approach and cross-sectional survey design. Accordingly, the data of 208 respondents was obtained using a questionnaire and analyzed using the Partial Least Square Structural Equation Model (PLS-SEM). Based on the result, the study found that both traditional advertising, advertising cost, advertising quality, and internet adverting have a positive significant effect on the performance of small business enterprises. As well, the study has confirmed the moderating effect of internet advertising on the relationship between traditional advertising and performance. However, the same effect was not found in the relationship between advertising cost, advertising quality, and performance. Hence, it is recommended that SMEs that seek to achieve an optimum level of performance, must embrace both traditional and internet modes of advertising, and as well, amortize advertising cost (expenditure) and add quality to advertising programs.
