ABSTRAK

Tingkat kesuksesan  perusahaan jasa dapat diukur dari seberapa besar tingkat kepuasan pelanggan terhadap pelayanan yang diberikan. Kepuasan merupakan gap yang terjadi antara persepsi dan harapan pelanggan. Perpustakaan merupakan salah satu lembaga penyedia jasa yang vital dalam dunia pendidikan, begitu pula dengan Perpustakaan Teknik Industri ISTN. Pada penelitian ini fokus analisis adalah pada fasilitas peminjaman buku yang diberikan kepada mahasiswa. Untuk melihat sistem kualitas jasa pada sistem perpustakaan digunakan dimensi kualitas jasa dalam “Assessment of Library Service Quality”, serta dengan menggunakan Dimensi Kualitas Jasa dari Bery & Parasuraman. Dari perhitungan gap diperoleh hasil bahwa semua dimensi bernilai negatif yang berarti persepsi pelanggan tidak sesuai dengan harapan mereka. Namun dari plot rata-rata dimensi pada diagram dua dimensi, didapatkan bahwa ada 7 variabel yang masuk pada kuadran 3 yang berarti mahasiswa TI ISTN sudah puas dengan pelayanan perpustakaan.

Published: October 2020

The times has made human needs are increasing, including information needs. Therefore, sending and storing data through electronic media requires a process that is able to guarantee the security and integrity of the data that requires an encoding process. Encryption is the process of changing an original data into confidential data that cannot be read. Meanwhile, the decryption process is a process where the confidential data received will be converted back into the original data. In this case the Advanced Encryption Standard (AES) algorithm is used as the latest cryptographic algorithm standard. The previous algorithm was considered unable to answer the challenges of the development of communication technology very quickly. AES is a cryptographic algorithm using the Rijndael algorithm that can encrypt and decrypt blocks of data over 128 bits with a key length of 128 bits. In this study the application of AES as a file security system is carried out, where the encryption and decryption process is carried out on the file. In testing the system a trial is performed on all files with different file sizes and for the results of the encryption process (ciphertext) in the form of files with the file format with the *.encrypted extension.

In this paper, the authors present a systematized methodology for modelling and analyzing the operating regimes of centrifugal pumps as working machines in electric drive systems. For solving, algorithms and calculation programs developed in the Mathcad programming environment were designed. For example, a representative case study was chosen of a condensing electric pump from the own services of a thermoelectric power plant with groups of 500 MW, driven by an induction motor with a squirrel cage rotor of 6 kV. It was thus possible to comparatively analyze two solutions for regulating the flow of a centrifugal pump in terms of energy efficiency.

Walking energy harvesting and self-powered tracking system based on triboelectric nanogenerators
Authors: Yao Mingliang , Xie Guangzhong , Gong Qichen , Su Yuanjie
Published: October 2020

Due to the extensive energy consumption and high population density in modern cities, the collection and use of scattered walking energy from the stream of people is crucial for the development of a green ecological city. Herein, a flexible undulated electrode-based triboelectric nanogenerator (u-TENG) was integrated to the floor to scavenge walking energy from pedestrians, promoting the ordered collection of disordered and scattered energy. Driven by the steps of human walking, the output of the as-fabricated u-TENG are an open-circuit voltage of 86 V and a short-circuit current of 6.2 μA, which are able to continuously light up 110 light-emitting diode bulbs. In addition, a self-powered location-tracking system was prepared for pedestrian volume counting and passenger tracing with the purpose of reducing energy consumption in public areas. The proposed walking energy harvesting device is flexible, feasible, and unaffected by season, climate, or location. This work not only proposes a strategy for mechanical energy harvesting in public areas, including subway stations, hospitals, shopping malls, and business streets, but also offers a novel solution for smart cities and low-carbon transportation alternatives.

Published: October 2020

Crown ethers are common building blocks in supramolecular chemistry and are frequently applied as cation sensors or as subunits in synthetic molecular machines. Developing switchable and specifically designed crown ethers enables the implementation of function into molecular assemblies. Seven tailor-made redox-active crown ethers incorporating tetrathiafulvalene (TTF) or naphthalene diimide (NDI) as redox-switchable building blocks are described with regard to their potential to form redox-switchable rotaxanes. A combination of isothermal titration calorimetry and voltammetric techniques reveals correlations between the binding energies and redox-switching properties of the corresponding pseudorotaxanes with secondary ammonium ions. For two different weakly coordinating anions, a surprising relation between the enthalpic and entropic binding contributions of the pseudorotaxanes was discovered. These findings were applied to the synthesis of an NDI-[2]rotaxane, which retains similar spectroelectrochemical properties compared to the corresponding free macrocycle. The detailed understanding of the thermodynamic and electrochemical properties of the tailor-made crown ethers lays the foundation for the construction of new types of molecular redox switches with emergent properties.

LANDSCAPE-SPATIAL FUNCTION OF RIVER AREAS IN THE CONTEXT OF URBAN DEVELOPMENT LANDSCAPE-SPATIAL FUNCTION OF RIVER AREAS IN THE CONTEXT OF URBAN DEVELOPMENT
Authors:   Mytishchi branch of N.E. Bauman Moscow State Technical University, Erzin I.V. , Zhukova O.A.
Published: October 2020

Abstract. For more than 30 years, since the end of the 1980s, Russia's urban planning policy has been in a state of reinterpretation. After the collapse of the system of total state control and planning, there was a period of almost uncontrolled point development of cities, focused on obtaining maximum benefits in the short term. This period of urban planning nihilism has also come to an end, but for the final exit from it and the acquisition of a full-fledged strategy for urban planning and social development in Russia, it is necessary to formulate the target parameters of the system. Among these parameters, of course, is the provision of conditions for the reproduction and increase of the main resource of the state – human potential. One of the necessary conditions for achieving this goal is to radically improve the quality of the human environment. A favorable environment is always based on natural and climatic conditions and the landscape of the area, or rather-a competent and rational use of the features of the landscape for the implementation of socially significant functions. One of the most obvious and important functions of the landscape is view – spatial. This article discusses the mechanics of implementing this function and its relationship with other functions of the Landscape as a subsystem of a settlement. Landscape-spatial function of the Landscape belongs to the category of aesthetic functions and is realized through the formation of positive impressions and emotions from the contemplation of beautiful landscape views, the compositional center and the main background of which are natural objects. Positive emotions from the contemplation of natural landscapes can reduce the psycho-emotional stress that occurs in a person under the influence of the architectural, technical and information environment of a modern city. The article also substantiates the high potential of riverine territories for the implementation of view – spatial functions.
Analysing fuzzy logic-based line following model car
Authors: Könczöl Boldizsár , Gál László
Published: October 2020

In our previous work a fuzzy logic-based controller was successfully applied to a line following model car utilizing Arduino Uno. Regarding fuzzy operations (t-norms), this logic has several implementations and our aim was to show how functional can be the chosen ones, and whether there are any remarkable differences among them. The fuzzy rules were very easy to create, except the drastic t-norm, all of them completed the tests, thus it can be stated that using fuzzy logic is convenient for line following. In this paper we focus on the impact of using a more capable microcontroller (Espressif ESP32) based board for the controller. Imrpovement of results is expected because of the higher computing performance of this board.
On the sliding mode control for precision machining
Authors: Rubio Rodriguez Luis , Ibeas Asier , Kollár László E.
Published: October 2020

Precision machining uses linear motor actuators in order to deal with robustness and stability in the broad range of cutting conditions. Those systems are demanding more sophisticated control algorithms in order to fulfil each time more exigent tolerances in the tendency to miniaturization of products and to face more robust dynamics. Sliding mode control family is natural approach to cope with mass and damping variation and external disturbances which are inherent characteristics of cutting processes. This paper compares conventional and super-twisting sliding mode controls on keeping the closed loop dynamics within requirements and reject disturbances created by the cutting forces.

Abstract

A 26-year-old male patient was admitted to Physical Medicine and Rehabilitation (PMR) inpatient clinic with a diagnosis of tetraplegia due to hypoxic-ischemic encephalopathy and spinal cord ischemia. The coexistence of both conditions is a rare condition. This study aims to examine how early treatment in terms of rehabilitation would benefit the patient's severe condition. Motor and functional evaluations were performed before and after the 8-weeks rehabilitation program. Biodex isokinetic strength and balance tests were used to evaluate lower extremity muscle strength and balance status. Also, the 6-minute walking test was performed, and the pinch and handgrip strength were measured. Disability of the Arm, Shoulder, and Hands Index (DASH) was used to evaluate the upper extremity functions, and the Functional Independent Measures (FIM) Questionnaire was used to determine the independence level. As a result of an early rehabilitation program, motor and functional status of the patient improved significantly.
The Importance of Radiology Consultation in Forensic Report Preparation: A Retrospective Study
Authors: AYAZ Nusret , MERAL Orhan , DOĞAN Mustafa
Published: October 2020

Objective: The aim of the present study is to draw attention to the importance of radiology consultation which is needed during medical evaluation and report preparation process.
Material and Method: The records of 72 cases who applied to Forensic Medicine outpatient clinic between June 2016 and October 2019 and whose consultations were requested from Radiology department to prepare a forensic report were examined retrospectively. Age and gender of the cases, the type of event, the date of the report, the reason for requesting consultation and the impact of the consultation on forensic report were investigated.
Results: Of the 72 cases included in the study, 58 (80,6%) were male, while 14 (19,4%) were female. The cases were between the ages of 17 and 78 and mean age was calculated as 36,6 (st ±:16.1) years. It was found that 43 (58,9%) of the consultations were requested because of “contradiction between the examination report prepared by radiology department and medical reports prepared by emergency or other clinical physicians”. Previous imaging reports of 21 (48%) of these consultations were changed in accordance with the opinions of physicians of emergency service or other clinics.
Conclusion: According to the legal legislation of our country, physicians are obliged to report judicial authorities and to prepare a judicial report if requested when they come across a judicial case. In order for forensic medical evaluation to be made in the most appropriate way and to prepare the forensic report, all examinations and treatments should be completed first. In addition, if there is a contradiction in the medical reports, examinations or consultation from the related clinical branch may be requested. Consultations make a significant contribution to the most accurate completion of forensic medical evaluation and the prepared medical report.

We use a sample of 532 star-forming galaxies at redshifts z ≃ 1.4–2.6 with deep rest-frame optical spectra from the MOSFIRE Deep Evolution Field (MOSDEF) survey to place the first constraints on the nebular attenuation curve at high redshift. Based on the first five low-order Balmer emission lines detected in the composite spectra of these galaxies (Hα through

), we derive a nebular attenuation curve that is similar in shape to that of the Galactic extinction curve, suggesting that the dust covering fraction and absorption/scattering properties along the lines of sight to massive stars at high redshift are similar to those of the average Milky Way sight line. The curve derived here implies nebular reddening values that are, on average, systematically larger than those derived for the stellar continuum. In the context of stellar population synthesis models that include the effects of stellar multiplicity, the difference in reddening of the nebular lines and stellar continuum may imply molecular cloud crossing timescales that are a factor of

longer than those inferred for local molecular clouds, star formation rates that are constant or increasing with time such that newly formed and dustier OB associations always dominate the ionizing flux, and/or that the dust responsible for reddening the nebular emission may be associated with nonmolecular (i.e., ionized and neutral) phases of the interstellar medium. Our analysis points to a variety of investigations of the nebular attenuation curve that will be enabled with the next generation of ground- and space-based facilities.
Supernovae in Orion: The Missing Link in the Star-forming History of the Region
Authors: Kounkel Marina
Published: October 2020

The Orion Complex is a notable star-forming region fragmented into several different populations with substantial differences in their phase space. I propose a model that attempts to explain the how the Complex has evolved into this current configuration. In the model presented here, the large-scale expansion can be attributable to a supernova that exploded 6 Myr ago. The remnants of this explosion can be seen as Barnard’s loop, as the center of the expansion is consistent with the geometrical center of the H ii bubble. This is similar to the H ii bubble and the ballistic expansion that is associated with λ Ori, a region that was also the site of an ancient supernova. Assuming that the Orion Complex originally formed as one long filament spanning from the bottom of Orion A to ψ
2 Ori (or potentially as far as λ Ori), Barnard’s loop supernova could have split the cloud, which led to the formation of Orion C & D. Furthermore, the shockwave that propagated into the filament could have swept along the gas through several parsecs, which led to the formation of the singularly most massive cluster in the solar neighborhood, the Orion Nebula Cluster. I also discuss other related nearby events, such as the formation of the Monogem ring and various runaways that have been ejected from the Orion Complex.
Evidence for Sulfur-bearing Species on Callisto’s Leading Hemisphere: Sourced from Jupiter’s Irregular Satellites or Io?

Published: October 2020

We investigated whether sulfur-bearing species are present on the icy Galilean moon Callisto by analyzing eight near-infrared reflectance spectra collected over a wide range of sub-observer longitudes. We measured the band areas and depths of a 4 μm feature in these spectra, which has been attributed to sulfur dioxide (SO2), as well as carbonates, in previously collected data sets of this moon. All eight spectra we collected display the 4 μm band. The four spectra collected over Callisto’s leading hemisphere display significantly stronger 4 μm bands compared to the four trailing hemisphere spectra (>3σ difference). We compared the central wavelength position and shape of Callisto’s 4 μm band to laboratory spectra of various sulfur-bearing species and carbonates. Our comparison demonstrates that Callisto’s 4 μm band has a spectral signature similar to thermally altered sulfur, as well as a 4.025 μm feature attributed to disulfanide (HS2). Our analysis therefore supports the presence of S-bearing species on Callisto but is not consistent with the presence of SO2. The significantly stronger 4 μm band detected on Callisto’s leading hemisphere could result from collisions with H2S-rich dust grains that originate on Jupiter’s retrograde irregular satellites or implantation of magnetospheric S ions that originate from volcanic activity on Io. Alternatively, S-bearing species could be native to Callisto and are exposed by dust collisions and larger impacts that drive regolith overturn, primarily on its leading side.

Effets sur le développement cognitif et langagier d’un placement en pouponnière, et adaptation de l’intervention orthophonique. Une étude de cas unique longitudinale
Authors: Duverger Jeanne
Published: October 2020

L’étude porte sur la compréhension du retard cognitif et langagier d’une jeune enfant en pouponnière, et présentant un retrait relationnel majeur. Face au profil atypique de ces enfants, nous avons voulu démontrer la pertinence de la démarche orthophonique de l’ajustement protologique et langagier, basée sur les interactions entre pensée, action et langage (créée par Lydie Morel). Cette étude de cas unique utilise une méthodologie quantitative de suivi longitudinal : tous les comportements de jeu, langagiers et communicationnels ont été recueillis et quantifiés, grâce à l’usage de la vidéo. Nous avons consacré des temps d’observations in situ et d’échanges avec les professionnels, afin de comprendre quels sont les éléments de la vie et de l’environnement de ces enfants qui peuvent avoir des incidences sur leur développement cognitif et langagier. Se pose la question de la persistance en France de séjours institutionnels de longue durée chez de jeunes enfants, et souligne la nécessité d’évaluation du développement et de l’état psychologique des enfants placés.

La estructura de la revolución darwinista
Authors: Alvarez Roldán Arturo
Published: October 2020

Este artículo discute la validez del concepto de «revolución científica» de Kuhn para explicar la construcción de nuevas teorías científicas. En concreto, critica la idea de salto o discontinuidad en el desarrollo de las teorías científicas implicada en el concepto kuhniano. Se analiza la estructura de la «revolución darwinista» con el fin de mostrar la relación que hay entre una nueva teoría científica y el saber científico previo —o en este caso, tecnológico— acumulado durante siglos. Se sostiene que el primer paso de Darwin en la construcción de su teoría de la evolución fue el descubrimiento del «principio de la selección» en los trabajos de criadores y hortelanos, y que fue el concepto de «lucha intraespecífica por la existencia (presión poblacional)» aplicado al principio de la selección lo que le permitió a Darwin construir el concepto de «selección natural».

Theophraste Renaudot, médico, filántropo y publicista en la Francia de Richelieu
Authors: González Flórez Roberto
Published: October 2020

Theophraste Renaudot es uno de los primerísimos publicistas que, con la consolidación de los Estados Modernos, pretenden acercar al limitado aunque influyente público lector, las grandes novedades, en el orden público y político, de la sociedad europea de su tiempo. Su «Gazette» la pondrá enteramente al servicio de la política antiespañola de Richelieu, de quien recibirá todos los apoyos. Y, sin embargo, la actividad filantrópica y científica, aunque en parte efímera, que desarrolló este hombre fecundo e imaginativo, no merece ser desdeñada. En una época en que apenas ninguna actividad pública se concibe al margen de las estructuras y normas corporativas, máxime cuando viene a vulnerar fortísimos intereses, las creaciones imaginadas por Renaudot aparecen tanto más llamativas, y su combate tanto más meritorio.

This paper focuses on documenting and beginning to qualify the sidekick roles within Kem Nunn’s Surf Noire narrative, Tapping the Source. Our goal is to examine the multifaceted and sometimes contradictory secondary roles created by the author as a starting point for further analysis of the mechanics that Kem Nunn employs in a work that has largely influenced the emerging Surf Noire genre.
When the second becomes number one: vice-presidential power in foreign and defense policy in the twenty-first century
Authors: Griffin Christopher
Published: October 2020

Richard Cheney was the most powerful Vice President in American history. His influence was primarily concentrated in the arena of national security policy. This article examines how Cheney was able to marshal unprecedented influence in the context of both the greater increase in vice presidential power since 1945 and the decision-making structure of the Bush Administration. A largely unexplored reason for Cheney’s influence was his close working relationship with Secretary of Defense Donald Rumsfeld, which allowed the two men to dominate the White House policymaking team on Iraq and counterterrorism policy.

Ciliary neurotrophic factor (CNTF) is a member of interleukin-6 type cytokine family. The CNTF receptor complex is a heterodimer including gp130 and CNTF receptor α (CNTFRα) proteins triggering the activation of multiple intracellular signaling pathways including AKT/PI3K, MAPK/ERK and Jak/STAT pathways. At present no data are available on the localization of CNTF and CNTFRα in prostate as well as on the role of CNTF in this organ. In this study we have analyzed the localization of CNTF and CNTFRα by immunohistochemistry and we have used PWR-1E cell line as a model for normal glandular cell to investigate the role of this cytokine. Our results show that CNTF and CNTFRa are expressed in the staminal compart of the prostate and that CNTF selectively inhibits ERK pathway. In conclusion, we suggest that CNTF could be considered as key molecule to maintenance epithelium homeostasis via pERK downregulation by an autocrine mechanism. Further CNTF studies in prostate cancer could be useful to verify the potential role of this cytokine in carcinogenesis.

Studies have shown that swertiamarin (STM) has multiple biological activities, but its anti-tumour effects and molecular mechanisms are still unclear. The present research aimed to validate the STM’s impacts on the proliferation, migration, and invasion of hepatocellular carcinoma (HCC) cells, and to study its potential mechanism. Two HCC cell lines were treated with STM. Tumour growth was observed by the mouse tumour xenografts model. HCC cell lines stably expressing T-cell lymphomas 1 (FRAT1) were generated by lentivirusmediated overexpression. Cell viability, proliferation, migration, and invasion were observed using Cell Counting Kit-8 (CCK8), the xCELLigence Real-Time Cell Analyzer system (RTCA), and transwell analysis, respectively. Quantitative real-time polymerase chain reaction (qRT-PCR) and Western blotting were used to observe the expression of FRAT1 and proteins related to the Wnt/β-catenin signalling pathway. Tumour growth was inhibited by STM in vivo. STM suppressed the proliferation, migration, and invasion of HCC cells. STM negatively regulated FRAT1 expression, whereas overexpressed FRAT1 blocked the anti-tumour function of STM. The results revealed that STM suppressed the FRAT1/Wnt/β-catenin signalling pathway. The findings of this study provide new insights into investigation of therapeutic strategies against HCC.

Published: October 2020

The 6th Generation Seismic Hazard Model of Canada (CanadaSHM6) provides the basis for seismic design values proposed by Natural Resources Canada for the 2020 edition of the National Building Code of Canada (NBCC 2020). This Open File includes OpenQuake compatible
source model files that will generate seismic hazard values as currently being proposed. Example hazard values at selected localities are included, in order to verify that the model has been implemented as intended. Once NBCC 2020 is finalized, this report will be superseded by a subsequent Open
File, to document the final model used to generate seismic hazard values using CanadaSHM6 for NBCC 2020.

PurposeIsocitrate dehydrogenase 1 (IDH1) mutations are the most common genetic abnormalities in low-grade gliomas and secondary glioblastomas. Glioma patients with these mutations had better clinical outcomes. However, the effect of IDH1 mutation on drug sensitivity is still under debate. Materials and MethodsIDH1-R132H mutant cells were established by lentivirus. IDH1-R132H protein expression was confirmed by western blot. The expression of ataxia telangiectasia mutated (ATM) signaling pathway and apoptosis-related proteins were detected by immunofluorescence and western blot. Temozolomide (TMZ) induced cell apoptosis was detected by flow cytometry. Tumor cell proliferation was detected by Cell Counting Kit-8. In vivo nude mice were used to confirm the in vitro roles of IDH1 mutation.ResultsWe established glioma cell lines that expressed IDH1-R132H mutation stably. We found that TMZ inhibited glioma cells proliferation more significantly in IDH1 mutant cells compared to wild type. The IC50 of TMZ in IDH1-R132H mutant group was less than half that of wild-type group (p < 0.01). TMZ significantly induced more DNA damage (quantification of γH2AX expression in IDH1 mutation vs. wild type, p < 0.05) and apoptosis (quantification of AnnexinV+propidium iodide–cells in IDH1 mutation versus wild type, p < 0.01) in IDH1 mutant gliomas compared to wild-type gliomas. The ATM-associated DNA repair signal was impaired in IDH1 mutant cells. Inhibiting the ATM/checkpoint kinase 2DNA repair pathway further sensitized IDH1 mutant glioma cells to chemotherapy. We found that IDH1 mutation significantly inhibited tumor growth in vivo (the tumor size was analyzed statistically, p < 0.05). Moreover, we confirmed that gliomas with IDH1 mutation were more sensitive to TMZ in vivo compared to wild type significantly and the results were consistent with the in vitro experiment. ConclusionThese results provide evidence that combination of TMZ and ATM inhibitor enhances the antitumor effect in IDH1 mutant gliomas.
Reciprocity, Mutuality, and Shared Expectations: The Role of Informal Institutions in Social Protection in Africa
Authors: Kpessa-Whyte M
Published: October 2020

Contemporary research in institutional analysis shows that institutions, broadly defined to include rules, policy, laws, conventions, shared expectations, and repeated practices, are instrumental in shaping human behaviour. This insight raises questions for understanding the dynamics of social care and protection in African countries where formal and informal institutions interact and compete in an environment characterized by two publics. Analytically, African countries reflect the notions of modern state, however due to their inability to connect with majority of the population informal rules practices that derived their logic of appropriateness and legitimacy from familial and kinship relationships have become essential institutional rules that mediate interaction and social exchange in social protection and beyond. The overbearing influence of informal institutional practices is however often ignored in the scholarly analysis of development and policies in the region, and this is due partly to a narrow focus on formal institutional reforms and a penchant for perceiving informality as deviant behaviour. This paper discusses the interface between informal institutions and social protection in Africa and draws attention to the role such institutions play in shaping the incentive structures and choices of political actors and citizens as well as the implications of informality in sub-Saharan African countries for broader socio-economic transformation.

In view of the serious pollution and high cost of treatment of acid mine drainage (AMD) in coal mine, the polyving akohol (PVA) and boric acid embedding cross-linking method was used to prepare the immobilized particles for treatment of AMD with sulfate-reducing bacteria (SRB) and nano zero-valent iron (nano-Fe0) as the main body. In order to explore the specification and dosage of each matrix component of immobilized particle, a series of single factor tests and orthogonal tests were carried out to determine the optimal ratio of each matrix component. The results shows that when the SRB quality additive percentage was 30%, the nano-Fe0 dosage was 4%, the corn cob particle size was 60 mesh and the dosage was 3%, the SO42-, Cr6+ and Cr3+ removal rates were 82.99%, 99.78% and 38.78%, respectively, the TFe and COD release rates were 4.26 mg·L-1 and 1,033.4 mg·L-1, respectively, and the pH value was 8.04, and the treatment effect was the best.

Hoy por hoy, el proceso de comercio no se limita únicamente al periodo de venta directa entre las empresas y consumidor, si no que este se expande hacia nuevos horizontes a través del proceso de postventa. En este marco contextual, las pequeñas y medianas empresas (PYMES) pueden utilizar el modelo de postventa como parte de su metodología estratégica para generar dependencia y preferencias en los consumidores hacia una marca, producto o servicio determinado a través del ofrecimiento de un servicio posterior a la venta de calidad. Consecuentemente, la lealtad de marca desemboca en un desarrollo comercial por en beneficio de las PYMES.
