Authors: Kamalova Anara
Published: January 2023

This article examines the impact of Covid-19 on the development of the tourism industry of the Kyrgyz Republic. In accordance with the purpose of the research the theoretical issues of the tourism market are studied, the problems of tourism development in the post-covid period are identified, the analysis of the main economic indicators of the tourism industry is made, and at the end recommendations for eliminating the impact of the pandemic on the development of the tourism industry of the country are offered. The Kyrgyz Republic, like other countries of the world, faced Covid-19 in 2020, which affected the development of the economy in general - the tourism industry in particular. Especially external tourism suffered: according to the statistical committee of the republic in 2020 the inflow of tourists to the country decreased by 74% compared to 2019, the share of the tourism industry in GDP decreased several times. The closure of the borders of the republic, the announcement of curfews in many cities of the country and other restrictions related to the pandemic led to a record reduction in the flow of tourists into the country. Major travel agencies were closed. Under such conditions, the effects of the pandemic persist to this day. Therefore, in this article we will try to find more effective ways out of this crisis and give some suggestions for further stabilization of the situation in the market of tourist services in Kyrgyzstan.
The Relation Between FDI Inflows and Environmental Pollution in CIS Countries
Authors: Gönültaş Suna , Demiral Ezgi
Published: January 2023

The role of the foreign direct investment (FDI) for the economic growth of countries is crucial in terms of the advantages it creates such as employment opportunities, providing long-term finance, facilitating competition, and technology spillover. Although countries are trying to attract FDI inflows and rise the volume of new projects, the concern of environmental issues is gaining much more importance than ever before.
In this respect, this study will aim to investigate the relationship between FDI inflows and environmental pollution from CIS countries for the period 2001-2014. By employing panel data analysis, the relation is analyzed by using Carbon dioxide emission as a proxy for environmental pollution. The data is obtained from the World Bank database for selected countries.
An Empirical Analysis of the Determinants of Regional Growth: The Case of Turkey
Authors: Ökmen Mahsum , Çalışkan Çavdar Şeyma
Published: January 2023

Since the beginning of economic literature, growth has been a key indicator of successful economic performance. Despite this consensus, discussions continue about which policies should be implemented for permanent growth. In particular, technological development stands out as the main explanatory factor in the analysis of economic growth, and according to endogenous growth theories, technology is determined by the conscious activities of actors. In this direction, while the effect of skilled labor on growth gained importance over time, the role of openness in creating technological externalities and learning effects has been another focus in the literature. Although these theories are tested empirically mostly on the basis of countries, the differences between the growth rates of the regions within the same country can directly affect the increase in total within the country. Hence, it would be useful to consider regional differences in order to propose the correct policies for high growth rates. For this purpose, in this study, impact of foreign trade and human capital on growth in 20 NUTS 2 regions between 2013 and 2020, will be examined using panel data analysis. The data used in the study were obtained from the TURKSTAT regional statistics database. As a result of the study, both trade openness and skilled workforce are found to increase regional growth. In this respect, policies such as providing investment and tax incentives to reduce the difference in trade volumes between regions and allocating resources for education to eliminate regional inequalities are likely to increase national growth through regional growth.
Recovery of Eurasian Tourism from Multiple Component Dysfunction Syndrome
Authors: Oralkan Ayça
Published: January 2023

Tourism has been an essential sector for the Eurasian economy in recent decades and is anticipated to get recovered at least gradually in 2022. In order for international travel esteem to reach pre-pandemic levels, it is necessary to regain the trust of potential tourists with practices aligned with new safety and hygiene standards. On the other hand, the ongoing conflict in Ukraine nurtures the oil and gas crisis in the Eurasian countries. Uncertainty in the global economic environment, which is another critical component of international tourism, builds a tendency to avoid purchasing decisions in consumer behavior. The aim of this paper is to determine the appropriate approaches based on the effective factors in the recovery process of tourism.
A Literature Review on Management Strategies, Organizational Commitment and Change in the Pandemic Process
Authors: Çelik Hilal , Sidar Dilek
Published: January 2023

With the emergence of deficiencies and mistakes in the implementation of management strategies of enterprises, it is seen that the sense of organizational commitment and the management understanding of organizations have begun to be questioned. In this research, organizational commitment and changes and transformations in the managerial field are examined. In the study, the results, and findings of studies in the literature carried out by different researchers from the beginning of the pandemic on the subject are evaluated. When we examine the literature, employees believe that a new leader and manager identity should be created with the pandemic. Another important fact: Employees consider it important to adopt an absolutely innovative and different management approach for a permanent and high job performance and organizational commitment. According to the researcher's impressions, the missing part of the managers in the evaluation and strategy development stages is that all actors of the process are not included in the evaluation. This situation poses an important problem for the sense of organizational commitment, especially by the employees. While the employees experienced a low job satisfaction due to the lack of management problem during the pandemic process, they also started to review alternative job opportunities for themselves. This shows that when there is a pandemic in terms of employees, business administrations that cannot think and design the returns of the process have to lose their employees. Therefore, it is possible to say that the pandemic has become a necessary and important change and transformation process for businesses.

Published: January 2023

The favor of domestic and foreign elements is an important factor in the rise of the stock market index, and in this context, it is expected that foreign capital coming to the country will play a role in increasing the stock market. Foreign capital investments, which come to the stock market in particular and to the country in general for investment purposes, lead to the concept of debt burden after a while and may cause that country to be considered risky. Problems in foreign debt and its solvency make the country risky, and when such a situation arises, it is possible that the country's stock market will be adversely affected. In other words, the hypothesis that foreign capital inflows affect the stock market positively up to a certain level and that it will affect the stock market negatively after a certain level is exceeded has been the subject of examination in the Turkish economy. For the period between 1998:1Q-2021:4Q, stock market and debt data were subjected to time series analysis. Since the series were stationary at the first difference, FMOLS regression analyzes were performed in order to clearly reveal the relationships between the variables considered. As a result of the analysis, it was found that the stock market index was positively affected by the increases in debt up to a certain level; However, when a certain debt threshold level is exceeded, it has been determined that debt negatively affects the stock market.

The Relationship of Service Sector Employees with Work Stress and Burnout
Authors: Imamaliyev Elvin , Musevi Sabina
Published: January 2023

The aim of this research is to reveal the relationship between job stress and burnout of service sector employees. The study consists of three parts. In the first part, the concept of service is examined. The concept of service emerged in the 17th century and expanded in developed and developing countries from the second half of the 20th century, surpassing the two important sectors of agriculture and industry, and gained great importance in the economy. The increase in people's free time, the increasing number of women in the workforce, and the increase in people's incomes have caused the service sector to gain importance in the economy. In the second part, the concept of stress and burnout is examined. Over time, all sectors have modernized and made people's daily lives easier, and at the same time, this modernization has increased the level of stress in people, and a feeling of burnout has emerged in people due to increased stress. The symptoms and characteristics of stress, which people cannot completely remove from their lives, also differ. Thus, people have coped with the resulting stress and burnout caused by stress by using different methods and have continued their lives. In the third part of the study, the relationships between work stress and burnout were discussed and research was conducted. As a result of the research, a significant and positively charged relationship was determined between job stress and the feeling of burnout. A meaningless and negatively charged relationship was found between work stress and lifestyle. A significant and negatively charged relationship was found between the feeling of burnout and lifestyle.
Impact of Small and Medium Enterprise-oriented Reforms in Azerbaijan on their Economic Performance
Authors: Majidli Famil
Published: January 2023

One of the main economic factors supporting the economies of the modern world is small and medium enterprises (SMEs), and in recent years the Azerbaijani government, which aims to minimize dependence on oil, is implementing reforms to support SME sector. The Small and Medium Business Development Agency of the Republic of Azerbaijan, established in 2017, is a clear example of this approach. The purpose of this article is to conduct a descriptive analysis of the impact of SME-supporting economic reforms on the economic performance of SMEs. The article analyzes the changes and trends in the macroeconomic indicators of SMEs in 2006-2019 based on the data of the State Statistics Committee of the Republic of Azerbaijan, and examines the impact of SME reforms on SMEs, especially after 2016. The figures suggest that the reforms have positive effects and there are growing trends in terms of both value added and employment created by SMEs. Despite these positive results, the share of SMEs in the GDP and in employment of Azerbaijan is still low compared to developed countries.
Factors Barring the Internationalization of Small and Medium Enterprises
Authors: Sabirli Vafa
Published: January 2023

The internationalization of small and medium enterprises (SMEs) has been growing worldwide over the past decade. For the internationalization of SMEs, a suitable function must be found to manage and control export operations. Undoubtedly, the initial goals of the SME management teams are that the capabilities of the management team and the characteristics of the company level are sufficient for internationalization to ensure the growth and profitability of the company. Looking at small and medium-sized enterprises, it is clear that some are looking for opportunities to expand in the international arena, while others are not. As a result of the theoretical researches, it has been seen that SMEs generally open up to international markets in order to increase their market share, increase their profitability and gain new customers. Lack of working capital, lack of information, lack of qualified personnel are among the main obstacles.
Exploration of In-Service Teachers’ Preparedness and Perceived Challenges about Inclusive Education in the United Arab Emirates
Authors: Meda Lawrence , ElSayary Areej , Mohebi Laila
Published: January 2023

The Coronavirus (COVID-19) global pandemic led to the deterioration of exclusive pedagogical practices in different learning institutions. This is because the pandemic forced teachers to make an abrupt instructional switch from face-to-face to online learning without having sufficient time to prepare. Various studies have reported that students with special needs in learning have to tolerate the burden of this tumultuous instructional transition. The educational policymakers have requested that in-service teachers in the United Arab Emirates (UAE) attend an inclusive education professional development program to equip them with knowledge and skills for teaching and supporting special needs children. The purpose of this study is to explore the extent to which in-service teachers were prepared to teach inclusively and the challenges they perceive after completing a six-month inclusive education teacher professional development (TPD) program. The study was done using a qualitative case study within an interpretive paradigm. Fourteen teachers from different schools across the country were purposively selected to complete an open-ended questionnaire and participate in semi-structured interviews. It was found that teachers gained comprehensive knowledge from the program and they felt confident and ready to implement inclusive pedagogical approaches in their classrooms.

The Impact of COVID: Case Study of an Academic English Reading Course at Qassim University
Authors: Alghannam Manal Saleh M.
Published: January 2023

This paper contributes to the burgeoning field of research investigating the educational effects of COVID. A questionnaire with both open and closed questions was administered to female takers of an Academic English Reading course at a Saudi university, eliciting responses about aspects of the quality of delivery of that course before and after the onset of COVID. From this quantitative and qualitative student evaluation of traditional class teaching (TCT) versus emergency remote teaching (ERT), some findings emerged that echoed those in the few comparable studies in the West. For example, certain features like the greater autonomy of the student in ERT than TCT were liked by some students but not others, while features such as the superiority of teacher-student communication in TCT were more uniformly approved. Furthermore, predictions from the literature such as that favouring TCT would be associated with greater self-efficacy, or a greater perceived degree of transactional interaction between student and teacher were not supported in the context of this study. Analysis of suggestions for ERT improvement leads to the conclusion that, at present, it may be that students need training to exploit the existing ERT, rather than that the ERT to be altered.

Load-Shedding in South Africa: An Immediate Threat to the Right to Education, “Section 29 Inquiry”
Authors: Matsheta Reginald Masilo , Sefoka Isaiah Mmatipe
Published: January 2023

The Constitution of the Republic of South Africa pledges in its preamble that “every citizen must equally be protected by the law, and further foster the quality of life of all citizens”. Thus, as a way of fostering the quality of life of all citizens, the Constitution in the Bill of Rights embodies a concoction of rights that enable citizens to exercise in nurturing their livelihood. In the midst of these rights, section 29 affords everyone the right to basic education. Against this backdrop, South Africa has failed for some time to resolve the electricity crisis infamously dubbed “load shedding”. Consequently, the load-shedding crisis confronting the country adversely impacts, and to some extent violates the Constitution in particular, section 29. In the same breath, media reports further ignite the reality that some learners during the examination period could not access, write or even attend to other educational activities due to load shedding. Therefore, the electricity crisis summonses the researchers to explore the degree of violation of section 29 and the effects that load shedding has on education and its infrastructure. Apart from that, the paper examines the role of load shedding apropos to the right to basic education by demonstrating that load shedding is severally and jointly liable for some challenges confronting the education sector. Finally, the paper establishes through judicial and legislative jurisprudence the State’s duty to afford everyone adequate access to basic education in South Africa.

Secara global, capaian pemberian ASI eksklusif saat ini masih tergolong rendah (<50%). Pemberian makanan prelakteal merupakan tantangan bagi keberhasilan ASI eksklusif. Studi ini bertujuan untuk menganalisis hubungan tempat tinggal di wilayah rural dan urban dengan praktik pemberian makanan prelakteal dan jenis makanan prelakteal yang diberikan. Penelitian dengan desain cross sectional ini menggunakan data sekunder SDKI Tahun 2017 dengan kerangka sampel blok sensus dari hasil Sensus Penduduk Tahun 2010 (SP2010). Variabel yang diteliti yaitu tempat tinggal subjek rural/urban, pemberian makanan prelakteal, dan jenis makanan prelakteal yang diberikan. Subjek penelitian ini sebanyak 8841 subjek. Analisis data yang dilakukan meliputi analisis univariat dan bivariat. Tidak terdapat hubungan antara tempat tinggal di wilayah rural/urban dengan praktik pemberian makanan prelakteal (p>0,05). Terdapat hubungan antara tempat tinggal di wilayah rural/urban dengan jenis makanan prelakteal yang diberikan yaitu susu selain ASI, air putih, air gula, susu formula, madu, kopi, dan pemberian cairan lainnya (p<0,001; p=0,003; p<0,001; p<0,001; p<0,001; p=0,011; p<0,001). Air putih, air gula, madu, dan kopi seringkali diberikan sebagai makanan prelakteal di daerah rural. Susu selain ASI dan susu formula merupakan jenis makanan prelakteal yang sering diberikan di daerah urban. Tempat tinggal di wilayah rural/urban tidak berhubungan dengan praktik pemberian makanan prelakteal tetapi berhubungan dengan jenis makanan prelakteal yang diberikan.

Bekam merupakan metode pengobatan tradisional bukan saja di Indonesia tetapi hampir menyebar di seluruh dunia. Bekam merupakan salahsatu bentuk Pelayanan Kesehatan Tradisional (Yankestrad). Selama pandemi dibutuhkan beberapa upaya meningkatkan sistem imun, diantaranya bekam.  Untuk mempermudah menemukan kebaruan dalam penelitian bekam diperlukan analisis bibliometrik. Metode penelitian ini adalah deskriptif analitik, dengan menggunakan aplikasi Publish or Perish (PoP) dan aplikasi VOSviewer_1.6.18. (VoS) pada bulan Januari 2022. Hasil; didapatkan 230 artikel penelitian bekam terindeks Scopus dari tahun 2012-2022; sepuluh jurnal teratas dalam mempublikasikan penelitian bekam; delapan penulis produktif tentang bekam; enam kata/term yang banyak digunakan dalam penelitian bekam; pada visualisasi network terdapat enam item dan tiga klaster, kekuatan hubungan secara keseluruhan berjumlah 30; tidak ditemukan term/kata imun atau yang berhubungan dengan sistem imun; tampilan overlay menunjukan tidak ada hubungan antar penulis dalam artikel bekam di jurnal terindeks Scopus dalam aplikasi PoP. Kesimpulan; secara kuantitatif, topik penelitan bekam, dengan melihat hasil statistik dari VoS dengan menggunakan term/kata imun atau sistem imun pada judul artikel masih sedikit sehingga tidak terdeteksi dan tidak nampak pada visualisasi network. Namun,  secara kualitatif masih perlu dilanjutkan dalam kajian sistematik literatur reviuw (SLR) untuk melihat dan menentukan variabel spesifik yang akan dikaji dari sistem imun.

Persebaran Ketahanan Rumah Tangga Balita Stunting: Studi Kasus pada Daerah Stunting Di Kelurahan Bakung, Kota Makassar
Authors: Suaib Fatmawaty , Mas'ud Hikmawati , Rusneni Rusneni , Muhtar Ghinia Anastasia
Published: January 2023

Latar Belakang : Kota Makassar sebagai pusat berbagai aktivitas di wilayah Indonesia Timur sudah tentu akan memiliki pendapatan daerah yang tinggi. Walaupun demikian ternyata di Kota Makassar masih terdapat penduduk miskin. Terlebih lagi di era pandemik covid ini banyaknya terjadi PHK ataupun perusuhan yang gulung tikar. Pendapatan rendah ini adalah salah satu faktor penyebab terjadi rawan pangan. Pendapatan yang rendah tidak saja menyebabkan terjadinya rawan pangan, tetapi dapat menyebabkan terjadinya stunting. Kenyataanya masih ada jumlah kasus stunting pada setiap kecamatan di Kota Makassar dan mengalami peningkatan. Kelurahan Bakung adalah salah satu wilayah di Kota Makassar yang memiliki kasus stunting di atas 100 kasus. Kelurahan Bakung terletak pada daerah peralihan antara urban (Kota Makassar) dan sub urban (Kabupaten Maros), yang mana wilayah sub urban merupakan wilayah ditinggali oleh masyarakat golongan ekonomi menengah ke bawah dan wilayah migrasi bagi masyarakat desa yang ingin tinggal di kota.Tujuan : Untuk mengetahui persebaran ketahanan pangan pada rumah tangga yang memiliki balita stunting di tengah pandemi covidMetode Penelitian : Metode dasar penelitian ini menggunakan metode Deskriptif Analisis spasial. Jenis penelitan deskriptif ini menggunakan metode Case Study yaitu penelitan yang menggambarkan secara mendetail tentang latar belakang, sifat maupun karakter khas dari suatu kasus terutama pada rumah tanggah balita stunting di Kelurahan Bakung. Penelitian ini akan menyebarkan sebanyak 130 kuesioner, dimana isi kuesioner berisi karakteristik rumah tangga, pendapatan dan pengeluaran pangan. Kemudian dilakukan food recall 24 jam untuk mengetahui tingkat energi dan protein dari suatu rumah tangga.Hasil Penelitian : Secara garis besar, sebanyak 6 RW yang memiliki tingkat ketahanan pangan pada kategori tahan pangan dan 3 RW memiliki tingkat ketahanan pangan pada kategori kurang pangan. Kurang pangan ini disebabkan kurangnya asupan energi dan protein yang dikonsumsi oleh suami dan istri pada RW 3, RW 4 dan RW 6. Untuk balitanya sendiri memiliki asupan energi dan protein pada kategori kurang dan defisit yaitu dibawah 70%. Hal inilah yang menyebabkan balita pada Kelurahan Bakung mengalami stunting.

Authors: Chipepa Fastel , Moakofi Thatayaone , Oluyede Broderick
Published: January 2023

Attempts have been made to define new families of distributions that provide more flexibility for modeling data that is skewed in nature. In this work, we propose a new family of distributions called Marshall-Olkin-odd power generalized Weibull (MO-OPGW-G) distribution based on the generator pioneered by Marshall and Olkin [20]. This new family of distributions allows for a flexible fit to real data from several fields, such as engineering, hydrology, and survival analysis. The mathematical and statistical properties of these distributions are studied and its model parameters are obtained through the maximum likelihood method. We finally demonstrate the effectiveness of these models via simulation experiments and applications to COVID-19 daily death data sets.

A simulation study for selected parameter values is presented to examine the consistency of the maximum likelihood estimates. Finally, some real data applications of the EHL-GGPS distribution are presented to illustrate the usefulness of the proposed class of distributions.
Asymptotic Properties of MLE's for Distributions Generated from an Exponential Distribution by a Generalized Log-Logistic Transformation
Authors: Gleaton James , Sa Ping , Hamid Sami
Published: January 2023

ABSTRACT.  A generalized log-logistic (GLL) family of lifetime distributions is one in which any pair of distributions are related through a GLL transformation, for some (non-negative) value of the transformation parameter k (the odds function of the second distribution is the k-th power of the odds function of the first distribution).  We consider GLL families generated from an exponential distribution.  It is shown that the Maximum Likelihood Estimators (MLE’s) for the parameters of the generated, or composite, distribution have the properties of strong consistency and asymptotic normality and efficiency.  Data simulation is also found to support the condition of asymptotic efficiency.   

 

Keywords Generalized log-logistic exponential distribution; asymptotic properties of MLE’s; simulation

UDC 517.9

We present some existence and uniqueness results for a class of functional integro-differential evolution equations  generated by the resolvent operator for which the semigroup is not necessarily compact. It  is proved that the set of solutions is compact.  Our approach is based on fixed point theory.  Finally, some examples are given to illustrate the results.
El interés internacional por combatir la destrucción intencional de Patrimonio Cultural
Authors: Luis Pérez-Prat Durbán
Published: January 2023

La actitud vandálica del Estado Islámico en Siria e Irak, encaminada a la destrucción deliberada del patrimonio cultural, ha generado una honda preocupación en la comunidad internacional ante un fenómeno que no es nuevo pero que, en esta ocasión, ha sido particularmente virulento. En este trabajo se examinan los seis enfoques en los que se concreta la reacción de la comunidad internacional ante tal devastación cultural, desde el establecido por la Convención de la Haya de 1954 hasta la acción del Tribunal penal internacional, pasando por las medidas adoptadas por el Consejo de Seguridad de las Naciones Unidas.
Entre o Solo e a Superfície de Projeção: Caminhos de Luta e Libertação em ´Mined Soil`, de Filipa César
Authors: Banito Tomé João Miguel
Published: January 2023

No âmbito das práticas de projeção fílmica que respondem ao apelo contemporâneo de uma reinvenção da materialidade, Mined Soil oferece um contributo essencial para questionar o excesso da imagem digital por via da afirmação do potencial expressivo da própria superfície de projeção. Através de um balanço entre o registo documental e o recurso a imagens de arquivo, Filipa César apresenta uma reflexão crítica sobre as práticas de extração mineira no Alentejo, reconvocando o pensamento marxista de Amílcar Cabral e a sua tese acerca da relação entre a libertação de um povo e a reivindicação do seu solo. O presente ensaio pretende defender que a auscultação do solo em Mined Soil estabelece um horizonte conceptual em que se joga também a arqueologia da superfície de projeção, acabando esta por ser desvendada como zona de tensão e conflito que questiona e, consequentemente, liberta o próprio meio.
The Great War, Fascism and the Athens Chater: Difficulty of the Italian Route
Authors: Nezzo Marta
Published: January 2023

The Athens Charter, which came out of the 1931 Conference, constitutes a vital hub for the growth of a shared European policy on restoration and monuments’ protection. It is a document whose background is extremely dense with experimentation and whose immediate future will be swallowed up by the tragedy of the Second World War. Precisely for this reason it is not useless to consider some shadows that characterize the Italian contribution to the works, resulted from the readjustment of the need of social and moral cohesiveness, emerging from the Great War, as a function of the construction of a fascist identity.
The Restoration of Monuments in Portugal: from Athens 1931 to Venice 1964 Charters
Authors: Neto Maria João
Published: January 2023

In Portugal, the restoration of monuments was directed by the General Directorate of National Buildings and Monuments (Direção-Geral dos Edifícios e Monumentos Nacionais — DGEMN) in the period amid the two world wars and, even after 1945, when Europe was being re-erected. This entity, centralized in the Ministry of Public Works, with its own section of technicians, will respond to the ideological objectives of the Estado Novo (New Regime) of António de Oliveira Salazar (1889-1970). The dictator himself has a particular commitment towards the actions of this organization and consistently exploits the image of the nation’s heritage under restoration as an example of the regime’s competence, commitment and effectiveness. His triumphalist vision of the History of Portugal, electing the heroes responsible for the nation’s golden moments, determines as prime targets for restoration the monuments from the past linked to these figures and facts. Thus, it is essential to establish an aesthetic and artistic correspondence between these and the historical time meant to evoke. This attitude conditions, from the outset, a practice of stylistic unity in the restoration of  monuments.
The departure from these ideological-political conditions was gradual, and the receptiveness to international principles was prompted by DGEMN’s affiliation to foreign organizations created after World War II. This came at a time when, internationally, the discussion of restoration attitudes was in the agenda.
From Athens to New York via Madrid. The Consequences of the 1931 Congress on the Cultural and Museum Policies Pursued by the Office International des Musées
Authors: Dragoni Patrizia
Published: January 2023

The Athens Conference on the Restoration of Historic Monuments and Buildings, held in October 1931, marked an important chapter in the work of the Office International des Musées (OIM). The aim of this paper is to examine the initial articles produced which addressed the theme of the conference, published in the journal Mouseion, and demonstrate how they influenced the way in which the OIM approached the organisation of two subsequent conferences, one held in Madrid in 1934 – in particular the section on the adaptation of ancient buildings for museum purposes, assigned to Italy – and another, on the social role of museums, which was planned for 1939, but the event did not come to fruition.
Entre Duas Guerras: Descobertas Arqueológicas no Egipto
Authors: Araújo Luís
Published: January 2023

O documento assinado em Atenas em 1931, que ficou conhecido por «Carta de Atenas», foi de grande importância para a proteção do património histórico em todo o mundo, com a criação de legislação adequada, criteriosas ações de restauro e novas técnicas de conservação, numa ampla colaboração internacional que hoje prossegue, agora sob a esclarecida e dinâmica proteção da Unesco. O Egito, um dos países mais ricos em monumentos e outros vestígios do passado, acompanhou desde o início as preocupações da reunião e levou à prática as recomendações essenciais contidas na «Carta de Atenas», ficando como exemplo o episódio da descoberta e estudo do túmulo do rei Tutankhamon em 1922.

Authors: Cruz António João
Published: January 2023

A Biblioteca Digital Ciarte (http://biblioteca.ciarte.pt), recentemente criada, tem como objectivos, por um lado, dar acesso à antiga literatura técnico-artística em português através de volumes em formato pdf resultantes de restauro digital propositadamente realizado e, por outro lado, disponibilizar informação sobre estas fontes fundamentais quer para o conhecimento das ideias, das técnicas e dos materiais de que são feitas as obras de arte e outros bens culturais, quer para a interpretação dos dados obtidos através de diferentes metodologias das Humanidades ou das Ciências. A apresentação aqui efectuada, além da divulgação da Biblioteca pelos interessados nestas fontes que são de difícil acesso, pretende igualmente expor os princípios que lhe estão subjacentes e as opções técnicas tomadas, que podem ser úteis para projectos semelhantes. O estreito e prolongado contacto com a grande diversidade de obras já digitalizadas serve de suporte à proposta de classificação tipológica desta literatura.
Comparation with Spectrophotometric and Liquid Chromatographic Methods of Pharmaceutical Forms of Ivermectin
Authors: TAŞPINAR Numan
Published: January 2023

Aim: Ivermectin is a semi-synthetic parasiticide that is used to treat parasitic disorders. Herein, In this study, LC chromatographic and UV spectrophotometric methods were developed and validated for the determination of ivermectin in different ivermectin preparations. Materials and Methods: In the LC chromatografic method, chromatographic separation was performed using an Agilent Extend-C18 column. Acetonitrile (20/80, v/v) and ultra-pure water was used as mobile phase at a flow rate of 1.2 mL/min. Eluents were determined at a wavelength of 245 nm and the values of ivermectin solutions were detected by spectrophotometric technique at the same wavelength. Lambert−Beer plots showed linear relationships at 6 different concentrations in the range of 10 to 60 μg/mL. Both methods adhered to the protocols published by ICH guidelines Q2(R1) to validate analytical methods. Results: The developed analytic methods were statistically validated. As a result of the analyzes performed with spectrophotometric and liquid chromatographic methods, it was determined that both methods were precise, accurate and robust with a RSD < 1% result. Recovery values were within the normal range (98-100%). Statistical comparison of both analytical methods was made and there was no statistical significance between them. Conclusion: These developed methods have been found to be reliable, fast, accurate and simple for tablet and injectable ivermectin forms and can be used for quality control tests. HPLC and UV spectrophotometric methods have shown that they are both adequate to determine the amount of ivermectin in raw materials, tablets and injectable solutions. These methods can be applied in a short time and easily. They can be used successfully in quality control analyzes to quantify and identify ivermectin in marketed formulations.
