The Impact of Countries’ Participation in the ICT Services Market on Economic Growth, CPI, and Exchange Rates
Authors: Oliinyk Andrii 
Published: May 2023

Abstract
Finding a way of achieving economic growth in the crisis period due to the COVID-19 pandemic, Russia’s invasion of Ukraine, and probable global regression aggravates the need for the implementation of managerial solutions of entering or intensifying participation in the perspective markets. The ICT industry has been a locomotive of economic development for the last decade for participating economies. The basic idea of the paper is based on the need to analyze the impact of countries’ participation in the ICT services market on their economic growth, consumer price indices (CPI), and exchange rates. The purpose was achieved by performing an analysis of the state and dynamics of the main indicators of the world ICT services market. The results show that the volume of ICT services exported and imported is growing. Moreover, we aimed to provide empirical evidence on the ICT services market’s impact on the economic parameters of the countries. We proposed a statistical model of Pearson’s r regression, based on the data of GDP values, CPI, and exchange rates of the 30 largest markets accounting for more than 90% of the ICT world market. The core results demonstrate stronger ICT services export and import correlation with GDP for economies with lower GDP per capita. The model shows a high success rate depending on variables. Based on the results obtained during modelling, propositions, and recommendations for countries with different socio-economic development levels were given.
تحليل واقع الاستثمار السياحي ومعوقاتها في إقليم كوردستان بالتركيز على محافظة دهوك
Authors: Mohammed Saeed Rasheed Hashim , Ramadhan Obaid Salah 
Published: May 2023

يلعب القطاع السياحي دوراً فعالاً ومؤثراً في عملية التنمية الاقتصادية والاجتماعية للعديد من الدول، وذلك من خلال آثارها الايجابية في خلق فرص الاستثمار من خلال جذب رؤوس الاموال المحلية والاجنبية، وخلق فرص العمل وزيادة الايرادات العامة، بالإضافة إلى نقل التكنولوجيا الجديدة ومهارات وأساليب الادارية الحديثة إلى داخل البلد، وبالتالي رفع من معدلات النمو الاقتصادي.
وتهدف الدراسة إلى بيان أهمية وخصائص ومحددات الاستثمار السياحي، ومن ثم مقومات البيئة الاستثمارية السياحية ومعوقاتها في اقليم كوردستان، ومن ثم تحليل وواقع الاستثمار السياحي من خلال التركيز على محافظة دهوك خلال المدة (2007ــ2018)، وكشف حجم رؤوس الاموال المستثمرة في هذا القطاع ومقارنتها بالقطاعات الاخرى من حيث النسب وعدد المشاريع المتنفذة. إذ تبين من التحليل انه وبالرغم من توافر كافة الشروط ومتطلبات تحقيق التنمية الاقتصادية والاجتماعية ورفع مساهمة القطاع السياحي في تكوين الناتج المحلي الإجمالي. إلا ان الاستثمار في هذا القطاع لم يكون بالمستوى المطلوب بسبب انعدام الرؤية والخطط اللازمة لتطوير السياحة وجعلها مورداً رئيسياً لإقليم كوردستان، والتهميش وعدم استغلال الامكانيات المادية والبشرية المتاحة بسبب عدم الاستقرار السياسي وظهور الخلافات بين الحكومة الاتحادية وحكومة اقليم كوردستان وتفاقم الازمة المالية والفساد والبيروقراطية في الاداء الحكومي. كما تبين من نتائج التحليل هذه الدراسة ان مساهمة الاستثمار الاجنبي في اقليم كوردستان وخصوصاً في محافظة دهوك خلال مدة الدراسة كان متواضعاً خصوصاً بعد سنة 2014. إذ كان الجزء الاكبر من الاستثمارات في هذا القطاع الحيوي كانت محلية، في الوقت الذي تحتاج هذا القطاع إلى تشجيع الاستثمار الداخلي والخارجي معاً بهدف تطويرها وتأهيلها إلى مستوى المطلوب.
THE CITY OF NOVY OSTROPIL IN THE MIDDLE OF THE 18TH CENTURY
Authors: Blyzniak Mykola 
Published: May 2023

The article attempts to analyze the socio-economic issues surrounding the development of the city of Novy Ostropil as one of the urban settlements on the territory of south-eastern Volyn in the middle of the 18th century. During this period, the city received confirmation of royal privilege for self-government and continued to use it in solving everyday problems of Magdeburg law. Novy Ostropil was owned by Franzyshko-Ferdinand Lubomyrskyi, who leased it for three years to Barbara-Ursula Sangushko in the middle of the 18th century. For this purpose, the rental inventory of the city was compiled in 1751 and has survived to our time. Therefore, the city first became the object of the profits of its owners and tenants. The agricultural sector played a critical role in the life of the city. Based on the inventory, a detailed architectural image and layout and a list of the buildings in the stockade were restored. The latter were made of pine and oak wood, some elements were made of linden, and the roofs were covered with straw, etc. Among the buildings in the Filvark complex was "Izba", which housed Governor S. Chernetsky. Vinnytsia was one of the city's Filvark structure's profitable objects. The city worked in the city "Entrance" on "Khmelnytskyi Black Way", where its exterior and interior were presented. On the river, Sluch’s two mills are arranged according to two and three millstones with steps and foils. 201 households in the city were recorded in the inventory (86.5% were Christians and 13.5% were Jews). Ukrainians dominated here, followed by Poles, and there were the fewest Jews. The Jewish communities of Novy Ostropil and Old Ostropil did not create a single kagal. It was divided into two separate parts, each of which was part of the Kagali of the two nearest cities, Lubar and New Polonny. The number of Jews in Novy Ostropil during 1751–1765 decreased significantly. Based on the analysis of the inventory, it was possible to obtain separate information about the Ostropil artisans and professional classes of residents of this city. The profession of a shoemaker was among the most sought-after and popular, followed by coopers. The occupation of crafts did not yet give a full opportunity to break with agriculture. 9.5 percent of the city's residents had liberation from general payments and work. In exchange for this, they were engaged to perform certain functions in the structure of the city's economy. Townspeople living in tenements made up 9.5% of all residents of Novy Ostropil. They were exempted from general city boards and individual duties, but not all. Craftsmen and those engaged in crafts (carriers, millers, winemakers), church ministers, etc., dominated among the peasants. As a whole, in the economic development of the city, primacy belonged to the agricultural sector; therefore, Novy Ostropil should be interpreted as an insignificant urban centre of the agrarian type.

Published: May 2023

The article examines the process of formation of the cultural and educational society «Prosvita» in the village of Visoka Pich of Zhytomyr County in 1920. Considering the lack of any historical materials about the educational center on the Internet, this article is actually the first attempt to analyze archival materials and carry out a comprehensive study of the activities of rural educators. The circumstances of the formation of «Prosvita» are clarified, its educational activities are reflected, in particular, the organization of training for illiterate and literate adults. The financial activity of «Prosvita» was tracked, thanks to which funds were obtained and expenses were incurred for the needs of the cell. As can be seen from archival materials, the society had the most diverse sources of income and expenses, which testified to its diverse work. Among the various forms of cultural and educational work, as evidenced by the documents, enlightened people paid special attention to the organization of concerts, plays, and rallies. In addition to material profit, they contributed to the education, development and entertainment of the population. The authors drew attention to the ascetic work of rural enlighteners: O. Mysko, M. Stolyar, V. Shtuly, and others. It was thanks to their dedicated work that it was possible to achieve acceptable results in 1920. The place and role of family parties in the lives of enlightened people and their families is analyzed. The publication presents tables showing the cultural and educational activities of the «Prosvita» society. They provide statistical information that testifies to the dynamic work of enlightened people. Its analysis makes it possible to trace achievements and gaps in the functioning of the village center.

Description of the subject. Fertilizers microdosing was tested for African leafy vegetables (ALVs) production to reduce the high rates of fertilizers usually applied to their production in West Africa. Objectives. This study aims to (i) evaluate the response of three ALVs (Amaranthus cruentus L., Solanum macrocarpon L. and Ocimum gratissimum L.) to cattle manure combined with urea-N microdosing and application timing and (ii) assess their partial factor productivity. Method. On-station trials were carried out over three growing seasons (2015 to 2017) in Northern Benin. Urea-N rates of 0, 10, 20, 30, 40 and 60 kg urea-N·ha-1 combined with 5 t·ha-1 of cattle manure (M5N0, M5N10, M5N20, M5N30, M5N40 and M5N60, respectively) and sole application as control (40 (M0N40) and 80 kg urea-N·ha-1 (M0N80)) and two urea-N application timings (T1 = 0 and T2 = 14 days after transplanting) were tested in a randomized complete block design with four replications. Results. The M5N60 treatment resulted in the highest A. cruentus fresh yield and improved leaf yield by 90 and 151% compared to M5N0, and the average of the two no-manure input treatments M0N40 and M0N80, respectively, while M5N40 treatment improved S. macrocarpon fresh yield the best by 23% compared to M5N0. For O. gratissimum, no significant difference was found between urea-N microdose rates. Besides, urea fertilizer application timing affected neither fresh yields nor partial factor productivity for any studied ALVs species. Conclusions. Reduced combination of urea-N and cattle manure is a promising nutrient management practice for ALVs production in West Africa as it improved yields while saving fertilizer for smallholder vegetable farmers.

Published: May 2023

Education creates reliable and competitive people resources, which determines a nation's success. Scholarship policies have a substantial impact on the growth of a nation, particularly in terms of enhancing the quality of human resources and access to quality education. Open access to education can help establish an improved education system. The Excellence Scholarships Program is part of the Indonesian government's goal to produce trustworthy and competitive human resources. This research used a qualitative descriptive methodology by tracing official government documents associated with the Excellence Scholarships program. This report analyzes the 2019-2020 implementation and impact of Indonesia's main scholarship program. This study examined program implementation using descriptive-qualitative research. According to the findings of this study, 2025 undergraduates won scholarships in the last two years. The procedures and aid distribution of the Excellence scholarship program are effective because they adhere to the predetermined flow and conditions, however, future improvements are required for the implementation of these scholarship programs: first, improving the principle of equal distribution of scholarship recipients to combat inequality, particularly in eastern Indonesia; and second, providing equal opportunities. This research also suggests further research could look into how the excellence scholarships program enhances scholarship recipients' quality of life and human resources.

INTRODUÇÃO: A dermatologia é uma especialidade predominantemente ambulatorial, no entanto, para um número significativo de paciente a internação é indispensável. Atualmente existem poucos estudos que permitam conhecer as particularidades e desfechos das internações dermatológicas, bem como orientar no cuidado das condições frequentemente encontradas no ambiente hospitalar. OBJETIVO: Caracterizar o perfil clínico, epidemiológico e a evolução dos pacientes internados pela especialidade da dermatologia. MÉTODOS: Foi realizada uma análise retrospectiva dos registros do prontuário eletrônico dos pacientes admitidos pela especialidade de dermatologia no HU-UFPI durante o período de janeiro de 2015 a dezembro de 2021 e preenchido instrumento de coleta elaborado pela autora. RESULTADOS: Foram analisados registros de 122 internações. A média de idade foi de 50,8 anos; gravidade da doença dermatológica e investigação foram motivos de admissão mais frequentes; 70,49% foi transferida de outro hospital; poucos pacientes foram considerados com indicação de isolamento; metade dos pacientes não possuía diagnóstico dermatológico previamente a internação; frequentemente os pacientes possuíam duas ou mais comorbidades (20,49%); anatomopatológico interno e exame clínico foram os principais recursos diagnósticos; a complicação mais frequente foi infecção hospitalar; 63,11% dos pacientes necessitaram de interconsulta e 20,49% foram transferidos para outras especialidades; 5,74% dos pacientes evoluíram com óbito. CONCLUSÃO: O perfil evidenciado foi de pacientes na sexta década de vida, distribuição por sexo quase igualitária e com média de tempo de internação de 12 dias. Hanseníase e seus estados reacionais foram o diagnóstico mais frequente. A integração com outras especialidades foi importante e refletida no número de interconsulta e transferências.
