Published: December 2022

Pelayanan terhadap publik harus memberikan kemudahan dalam tukar-menukar informasi, transaksi, dengan tingkat keamanan yang tinggi. Masalah ini dapat dijumpai pada lingkungan kerja apa saja yang membutuhkan fakor-faktor seperti mobilitas tinggi, keamanan data, ketangguhan terhadap gangguan, kestabilan dan kualitas kerja. Dalam hal ini ada beberapa hal yang membuat petugas pajak kewalahan pada saat melakukan pelayanan terhadap wajib pajak karena pengolahan data yang belum menggunakan sistem yang lebih efektif, untuk melayani satu orang wajib pajak memerlukan waktu yang cukup lama sehingga menyebabkan wajib pajak mengeluh terhadap pelayanan yang kurang efektif. Dan hal tersebut juga menyebabkan penumpukan antrian. Oleh karena itu diperlukannya sebuah sistem berupa aplikasi berbasis web yang mampu mempermudah petugas pajak dalam mengelolah data pajak kendaraan, dan wajib pajak dalam melakukan pengecekan jumlah pajak kendaraan. Hasil dari penelitian berupa aplikasi website sebagai wadah bagi petugas pajak dalam melakukan pengelolaan data pajak kendaraan, dan mempermudah petugas pajak dalam melakukan proses pelayanan pajak kendaraan.

Published: December 2022

AbstractThis paper focuses on questions of entrepreneurial education's (1) perceived usefulness, (2) effect on developing entrepreneurial competence and (3) potential to increase entrepreneurial intention. The aim of this study is to assess the impact of entrepreneurship education on the development of students' entrepreneurial competences and career plans in the Republic of Moldova. In order to explore this subject, a survey was conducted among young citizens, mainly university students and students of vocational secondary schools, who have studied entrepreneurship-related subjects. The questionnaires were completed by 289 students from 20 educational institutions in the Republic of Moldova. The statistical analysis of their answers allowed conclusions to be drawn about the positive relationship between entrepreneurship education, the development of entrepreneurial competences and the students' entrepreneurial intentions. Entrepreneurial studies are perceived to be useful by students not only in the context of starting a new business, but also for a career as an employee, and even in various social and political situations. Some gender-specific differences were also revealed concerning perceptions of competence development and their usefulness which can be important inputs for further development of entrepreneurship education.
DETERMINATION OF INHERITANCE RELATIONS AND RESTRUCTURING OF SOFTWARE CLASS MODELS IN THE PROCESS OF DEVELOPING INFORMATION SYSTEMS
Authors: Kungurtsev O. B. , Vytnova A. I. 
Published: December 2022

Context. The implementation of different use-cases may be performed by different development teams at different times. This results in a poorly structured code. The problem is exacerbated when developing medium and large projects in a short time.
Objective. Since inheritance is one of the effective ways to structure and improve the quality of code, the aim of the study is to determine possible inheritance relationships for a variety of class models.
Method. It is proposed to select from the entire set of classes representing the class model at a certain design stage, subsets for which a common parent class (in a particular case, an abstract class) is possible. To solve the problem, signs of the generality of classes have been formulated. The mathematical model of the conceptual class has been improved by including information about the responsibilities of the class, its methods and attributes. The connection of each class with the script items for which it is used has been established. A system of data types for class model elements is proposed. Description of class method signatures has been extended. A method for restructuring the class model, which involves 3 stages, has been developed. At the first stage, the proximity coefficients of classes are determined. At the second, subsets of possible child classes are created. At the third stage, an automated transformation of the class structure is performed, considering the identified inheritance relationships.
Results. A software product for conducting experiments to identify possible inheritance relationships depending on the number of classes and the degree of their similarity has been developed. The results of the conducted tests showed the effectiveness of the decisions made.
Conclusions. The method uses an algorithm for forming subsets of classes that can have one parent and an algorithm for automatically creating and converting classes to build a two-level class hierarchy. An experiment showed a threefold reduction in errors in detecting inheritance and a multiple reduction in time in comparison with the existing technology.
SYNTHESIS OF THE SYMBOLOGIES OF MULTICOLOR INTERFERENCE-RESISTANT BAR CODES ON THE BASE OF MULTI-VALUED BCH CODES
Authors: Sulema Ye. S. , Drozdenko L. V. , Dychka A. I. 
Published: December 2022

Context. The problem of constructing a set of barcode patterns for multicolor barcodes that are resistant to distortions of one or two elements within each pattern is considered.
Objective. The goal of the work is ensuring the reliability of the reading of multi-color barcode images.
Method. A multicolor barcode pattern has the property of interference immunity if its digital equivalent (vector) is a codeword of a multi-valued (non-binary) correcting code capable to correct errors (distortions of the pattern elements). It is shown that the construction of barcode patterns should be performed on the basis of a multi-valued correcting BCH code capable to correct two errors. A method is proposed for constructing a set of interference-resistant barcode patterns of a given capacity, which ensure reliable reproduction of data when they are read from a carrier. A procedure for encoding data with a multi-valued BCH code based on the generator matrix of the code using operations by the modulo of a prime number has been developed. A new method of constructing the check matrix of the multivalued BCH code based on the vector representation of the elements of the finite field is proposed. A generalized algorithm for generating symbologies of a multi-color barcode with the possibility of correcting double errors in barcode patterns has been developed. The method also makes it possible to build symbology of a given capacity based on shortened BCH codes. A method of reducing the generator and check matrices of a multi-valued full BCH code to obtain a shortened code of a given length is proposed. It is shown that, in addition to correction double errors, multi-valued BCH codes also make it possible to detect errors of higher multiplicity – this property is enhanced when using shortened BCH codes. The method provides for the construction of a family of multicolor noise-immune barcodes.
Results. On the basis of the developed software tools, statistical data were obtained that characterize the ability of multi-valued BCH codes to detect and correct errors, and on their basis to design multi-color interference-resistant bar codes.
Conclusions. The conducted experiments have confirmed the operability of the proposed algorithmic tools and allow to recommend it for use in practice for developing interference-resistant multi-color barcodes in automatic identification systems.
Efecto de gremios de hongos micorrícicos arbusculares aislados de un ambiente desértico sobre el crecimiento de frijol <i>Phaseolus vulgaris</i> bajo una condición de déficit hídrico
Authors: Herrera-Corrales Laura C. , Ospina-Alzate David F. , Ocampo-Jiménez Omar 
Published: December 2022

Los hongos micorrícicos arbusculares (HMA) aumentan la capacidad de las plantas para resistir o tolerar condiciones estresantes como las ocasionadas por la deficiencia de nutrientes, el ataque de patógenos, la presencia de contaminantes químicos y el déficit hídrico. Sin embargo, estos hongos tienen diferentes efectos sobre las plantas. Estos efectos, son regulados por la planta, las condiciones ambientales y el hongo, de tal manera, que aunque no existe especificidad entre los simbiontes, no todas las interacciones micorrícicas terminan siendo mutualistas, así, la búsqueda de hongos micorrícicos arbusculares infectivos y efectivos es primordial para una simbiosis benéfica. En este trabajo se seleccionaron cinco sitios de muestreo ubicados en la Alta Guajira colombiana, en los municipios de Riohacha y Maicao, considerando la comunidad de especies vegetales y las características físicas del suelo. Los hongos se multiplicaron en suelo estéril y una mezcla de especies vegetales (Phaseolus vulgaris, Calendula officinalis, Lolium perenne y Phaseolus vulgaris) usadas como plantas trampa. Después de 10 semanas de multiplicación se seleccionaron dos gremios en función del contenido de esporas. Se evaluaron 6 tratamientos con 7 repeticiones por tratamiento: dos gremios de HMA (G 3 y G 4) y un control sin hongo (C) y bajo dos condiciones de humedad: sin agobio hídrico (SAH) y con agobio hídrico (AH). Se evaluó el efecto de los gremios y la condición de humedad sobre la altura de la planta, área foliar, número de hojas, peso seco radical y diámetro del tallo de la planta de frijol (Phaseolus vulgaris) y el porcentaje de colonización micorrícica (hifas, vesículas y arbúsculos). Cuando las plantas se mantuvieron sin estrés hídrico el gremio que mejores resultados tuvo fue G 3 y para las plantas bajo agobio hídrico el mejor gremio fue G 4. Los hongos micorrícicos nativos de clima desértico pueden ser una alternativa efectiva para usarse en cultivos expuestos a condiciones de sequía.
What do <i>Anolis</i> eat?: evaluation of sexual dimorphism and geographic variation in the diet of <i>Anolis ventrimaculatus</i> (Squamata: dactyloidae) in Colombia
Authors: Barragán-Contreras Leidy A. , Calderón-Espinosa Martha L. 
Published: December 2022

Anolis lizards exhibit high morphological diversity, partially related to variation in structural resource use, that probably influences foraging behavior and prey selection of individuals and species. Anoles are largely insectivorous: most species are generalists/opportunists and few are specialists. Dietary differences between sexes and among individuals from different populations have been observed in several species. Sexual size dimorphism, spatial niche divergence between sexes and species, competition and food availability are some of the factors responsible for these differences. We characterized the diet of Anolis ventrimaculatus (Squamata: Dactyloidae), a species with sexual size and shape dimorphism, widely distributed in highland Colombian environments. Stomach and proximal intestinal content of preserved adults were analyzed. Prey items were classified to order and, when possible, to family. A. ventrimaculatus eats variable preys (mostly Hymenoptera, Coleoptera, and insect larvae) and is classified as a generalist/opportunist. Vegetal debris, shed skin, and stones presumably were ingested incidentally. Diets of males and females are similar. Sexual dimorphism and geographic variation in the diet were minimal. Males and females exhibited differences in total number and percentage of use of frequently consumed prey (Orthoptera and Hymenoptera), and these differences varied among localities. Total prey numbers consumed by females also varied among localities, whereas consumption of Coleoptera and Orthoptera varied in both sexes. Differences in prey size could explain the variation in prey number between sexes, with males probably ingesting larger items. Variation in prey availability (most likely attributable to differences in structural microhabitat use), sample sizes and dates of collecting events could explain minor geographic variation in some aspects of the foraging ecology in this species.
Una aproximación empírica a la relación entre el desempleo y las vacantes para Popayán, 2001-2005
Authors: Tobón Arias Julián Durán , Mora Jhon James Mora 
Published: December 2022

Este artículo presenta evidencia empírica sobre la relación entre las vacantes y el desempleo, a través de la Curva de Beveridge, para la ciudad de Popayán entre 2001 y 2005, siguiendo un modelo de datos de panel por áreas de desempeño. Los resultados del modelo muestran que la elasticidad del desempleo con respecto a las vacantes es estadísticamente significativa y positiva. Este resultado puede deberse a la existencia de shocks asimétricos en los distintos sectores de la economía payanés, que se estarían reflejando en la dinámica de las áreas de desempeño laboral. De esta forma, se estaría presentando una recomposición de las actividades económicas de la ciudad de Popayán durante el período estudiado. Palabras clave: datos de panel, desempleo, vacantes, Curva de Beveridge. Clasificación JEL: C23, E24, J4. Abstract: This article presents empirical evidence about the relationship between job openings and unemployment through a Beveridge Curve for the city of Popayán between 2001 and 2005, following a panel data model by work areas. The results of the model show that the elasticity of unemployment with respect to job openings is statistically significant and positive. This result can be due to the existence of asymmetric shocks in the different sectors of Popayán’s economy that would be reflected in the dynamics of the work areas. Thus, a recomposition of the economic activities of Popayán’s economy would be taking place during the time period under study. Keywords: panel data, unemployment, job openings, Beveridge Curve. JEL classification: C23, E24, J4. Résumé: Cet article fait une étude empirique sur la relation entre les offres d’emploi et le chômage pour la ville de Popayán entre 2001 et 2005. Pour ce faire, nous utilisons la Courbe de Beveridge dans un modèle sur données de panel pour les différents types d’emploi. Les résultats du modèle montrent que l’élasticité du chômage par rapport à l’offre d’emploi est statistiquement significative et positive. Ce résultat peut être expliqué par des chocs asymétriques dans les différents secteurs économiques de la ville de Popayán. Ces chocs asymétriques se reflètent sur la dynamique des différents types d’emploi. Ainsi, il existerait une recomposition des activités économiques de la ville de Popayán pendant la période étudiée.

Evaluación de la gestión privada del servicio público educativo en Medellín
Authors: Barrientos Jorge Hugo , Rios Paul 
Published: December 2022

La alcaldía de Medellín emprendió en 2002 un programa de cobertura educativa dirigido a jóvenes en edad escolar en lugares donde la oferta escolar pública era reducida. El programa consistió en dar en concesión colegios de propiedad estatal a entidades educativas privadas. El objetivo de este trabajo es evaluar el impacto del programa de concesión en dos frentes, el desempeño académico, la deserción y la reprobación de los alumnos. La evaluación se hace comparando individuos, en colegios en concesión, quienes son muy parecidos a aquellos que atendieron colegios públicos. Los resultados muestran que los estudiantes en colegios en concesión han tenido un desempeño inferior a sus pares en colegios públicos, así como mayores tasas de deserción y reprobación. Palabras clave: concesión, emparejamiento, contrafactual, grupo de tratamiento y control, propensity score. Clasificación JEL: C14, C21, I20. Abstract: In 2002 the local government of Medellin started a program for school-age children who were not covered by the educational public system. The program, called Concession Schools, was designed to provide private educational management by means of public resources where public supply was reduced. In this paper we are interested in investigating the impact of this program on academic performance, dropout, and pass rates. To this aim we match individuals at concession schools with those at public ones by computing the probability of attending concession institutions. In spite of the good reputation for Concession Programs, we found that students at concession schools had a lower performance than their peers at public schools, as well as higher dropout and lower pass rates. Keywords: concession, matching counterfactual, treatment and control groups, propensity score. JEL classification: C14, C21, I20. Résumé: La Mairie de Medellin a entrepris pendant l’année 2002 un programme de couverture éducative adressée aux jeunes en âge scolaire dans les arrondissements mal desservies par l’éducation publique. Le programme donne en concession à certaines institutions éducatives privées les établissements scolaires publics. L’objectif de cet article consiste à évaluer l’impacte de ce programme en ce qui concerne la performance académique, la désertion scolaire et redoublement des élèves. L’évaluation présente une comparaison entre les individus des établissements gérés par le secteur privé et ceux d’établissements publics. On montre que les étudiants des établissements gérés par le privé ont eu une performance inferieur à ceux des établissements publics ainsi qu’un taux plus élevé de désertion scolaire et de redoublement.

Volatilidad de los flujos de capital hacia paises en desarrollo: evidencia para América Latina, 1970-2002
Authors: Rhenals Remberto , Torres Alejandro 
Published: December 2022

Resumen:
La dinámica de los flujos de capital hacia los países en desarrollo en las
últimas décadas, ha puesto nuevamente en el centro del debate la discusión sobre sus
beneficios y costos. El objetivo del presente artículo es analizar el comportamiento de los
flujos de capital entre 1970 y 2002, su grado de volatilidad y sus efectos sobre el desempeño macroeconómico de América Latina. La volatilidad se mide mediante el coeficiente de variación, que se calcula de dos formas. Los resultados muestran que la volatilidad de los flujos de capital y del crecimiento de la región no parece haber aumentado, pese a la gran importancia adquirida por los flujos privados de capital desde principios de los noventa.
