Published: August 2024

In order to alleviate environmental pollution and the waste of resources caused by improper disposal of fungal residue, this study used fungal residue waste, which was treated with NaClO alkaline solution and nitric acid ethanol method for rough fiber preparation. The enzymatic hydrolysis of cellulase conditions were optimized using response surface optimization method, and the optimal preparation parameters were: enzyme addition of 5000 U/g, enzymatic hydrolysis temperature of 52 °C, enzymatic hydrolysis time of 2.65 h, and solid-liquid ratio of 1:20. The Fr-MCC purity reached over 97%. The Fr-MCC obtained had an irregular granular or lamellar aggregation morphology, typical I-type cellulose crystal structure and molecular features, good thermal stability, and was similar in properties to commercial MCC. It was judged to be suitable for further processing and manufacturing of biological base materials. This approach was shown to improve the utilization efficiency of cultivation residues, reducing environmental pollution caused by the accumulation of cultivation residues, and providing new methods and ideas for the preparation of MCC and other bio-based materials.

Authors: Kaneko Shunsuke , Kim Hyun Bae , Yoshioka Takuyuki
Published: August 2024

This study used a sub-model within system dynamics to simulate and quantify CO2 emissions in the residential sector, focusing on the Nishikawa forestry region in Saitama Prefecture. The model evaluated emissions from the life cycle of houses, including production, transportation, use, maintenance, and disposal. The business as usual (BAU) scenario projects annual new housing inflows. The woody biomass utilization (WBU) scenario showed a 10% carbon reduction over 30 years by replacing new housing with timber construction, despite increased emissions from new constructions. The study highlights the economic benefits of utilizing carbon credits to support reforestation, making it possible to secure the sustainability of regional forestry to supply timber materials to the residential sector.
The Beginning of the Registration of Estonian Books in Printed Works as Compared with that of the Other Nations of the Baltic Sea
Authors: Aarma Liivi
Published: August 2024

Jam Amos Comenius described the relation between the world and book in following words: the world is a maze, from which the books can lead us out. The idea can be further developed if we claim that the maze of the realm of books can be solved by technological means of bibliography. Every new step in technology could be described as an annual ring of tree growth, as concentricity. The advent of typography favoured publishing of books and bibliographies in national languages - the same holds true also in comparative treatment of national printed works in Baltic Sea region.
We could point out that the bibliography in the countries surrounding Baltic Sea has developed according to general regularity, more or less synchronically. Here l would emphasise that it is the historical phenomenon of networking, much similar to that of modem computer networks. Despite the fact that the fruits of typography were accessible only for quite a limited part of the society the ideas and models spread everywhere, evoking analogous phenomena in various countries and places.
Historical national bibliography is highly valued by Polish bibliographers Anna Migon and Marta Skalska-Zlat, who emphasise the contribution it has given to the research and representation of modem national literature.

This is in contrast to current people who assume often sitting position during their work, traveling by car, sitting in front of a television set.
Burnout and depression in medical students
Authors: Gökdemir Özden
Published: August 2024

During their training and patient care process, medical students are exposed to a variety of stressors such as academic pressure, study schedule, sleeplessness, and anxiety. This stress may impair students’ ability to focus or reduce their working efficacy and productivity. Surveys in many countries show that medical students have a high prevalence of depression and poor mental health conditions due to stress, poor coping strategies, and inappropriate counseling. 80% of over 12,000 medical students reported burnout, alcohol abuse/dependence, or depressive symptoms in a survey. Another study discovered that medical students, residents/ fellows, and early-career physicians were more likely to be burned out and depressed than the general population.

Authors: Eroğlu Nuray , Büyük Akbaş Demet
Published: August 2024

Objective: In our study, it was aimed to learn the thoughts of women living in İnegöl about breast milk and breastfeeding, and to determine the factors affecting their attitudes and behaviors on this subject. Methods: A cross-sectional study included 1624 women between the ages of 18-60 and living in İnegöl between April 10 and June 10, 2023. While the data were collected by using the introductory information form, breastfeeding/breastmilk attitude form and the Google survey method, they were presented as numbers and percentages. The chi-square test was used to compare categorical variables and the p<0.05 level was accepted as statistically significant. Results: It was determined that 1153 (71%) of 1624 women also had children and 92.9% of them gave breast milk. Considering the factors affecting breastfeeding status; It was determined that as age increases, breastfeeding increases, as education level increases, breastfeeding rate decreases, working decreases the breastfeeding rate, vajinal birth increases the breastfeeding rate and the support of the spouse increases the breastfeeding rate (p<0.001). Breastfeeding levels of women who received training on breastfeeding from a pregnancy school or a breastfeeding consultant were found to be significantly higher (p<0.001). Conclusion: With this study, it was seen that the demographic data of women between the ages of 18-60 living in İnegöl district affected their attitudes towards breastfeeding-breastmilk. It can be suggested that more importance should be given to pregnant schools or a breastfeeding consultant staff in the district due to the high rate of breastfeeding in those who received training from pregnant school-health personnel about breastfeeding.
Livedo reticularis related to physical activity: A case report
Authors: Usanma Koban Buğu , Coşgun Tahsildaroğlu Asena
Published: August 2024

Livedo reticularis is a skin finding consisting of transient or persistent, macular, violaceous, connecting rings that form a netlike cyanotic pattern. This appearence may be caused by any situation which is related to increase of visibility of the venous plexus under the dermal layer. Thinning of the dermis in elderly people is one of the causes of this lesion without any pathology. Venodilation (triggered by hypoxia or autonomic dysfunction) and blood deoxygenation (ie. venous thrombosis, vasospasm or increased blood viscosity) are two major causes of venous plexus visibility. Although, in most cases livedo reticularis is a result of a physiological response to cold exposure, it can also be a cutaneous sign of an underlying disease such as antiphospholipid syndrome or Sneddon’s syndrome. In this paper, we present a 40 year old female patient having cutaneous manifestations exacerbated by physical activity and who got primary livedo reticularis diagnosis after the exclusion of any underlying pathologies and relation to temperature as in the case of physiological livedo reticularis. Albeit exercise is recommended for the treatment of livedo reticularis because increased circulation helps to dilate the blood vessels throughout the body it is contraversial as in this case exercise was what exacerbated the situation.
A Case of Atrial Flutter diagnosed at the Family Health Center
Authors: Uslu Ayşenur , Derici Ayşenur
Published: August 2024

Atrial flutter (AFL) is the most common supraventricular arrhythmia that develops as a result of various metabolic and cardiopulmonary disorders, following atrial fibrillation. Risk factors for developing AFL include many chronic diseases such as hypertension. The diagnosis of AFL is made by electrocardiography (ECG) taken during the monitoring of chronic diseases, sometimes due to clinical symptoms and sometimes without causing symptoms. Patients with this arrhythmia are at a high risk of thromboembolic events. Timely diagnosis and initiation of treatment in these patients are of paramount importance. Family practice provides services for early diagnosis, treatment, follow-up and rehabilitation of patients in primary care. In this case report, it is aimed to discuss the process of diagnosing AFL in a patient who was called to the family health center for chronic disease follow-up within the scope of the Disease Management Platform (HYP) application and who did not have any complaints, and to emphasize the importance of primary health care services in chronic disease follow-up.
The effect of body dysmorphic disorder, eating disorders and stigma in the obesity epidemic
Authors: Sarıkaya Seval
Published: August 2024

In this review, our aim is to draw attention to the significance of psychiatric disorders in the obesity epidemic, explain the relationship between eating disorders and body image distortion with obesity, raise awareness about the stigma that may accompany obesity, and emphasize the role of primary care in the treatment of obesity. A meta-analysis revealed bidirectional relationships between depression and obesity, with a 55% increased risk of depression over time in obese individuals and a 58% increased risk of obesity in individuals experiencing depression. In the literature, it has been noted that individuals with obesity, compared to healthy individuals, may encounter weight discrimination leading to psychological conditions such as anxiety, due to less reported social support. Discrimination against individuals with a high body mass index can lead to dissatisfaction with weight and appearance, serving as a risk factor for accompanying eating disorders. In eating disorders, body dissatisfaction is a significant risk factor It has been suggested that primary care in obesity management can have a significant impact, providing benefits for at least 20% of individuals experiencing weight loss clinically. Obesity, more prevalent in Western societies, can lead to stigmatization and numerous psychiatric disorders. Conversely, many psychiatric conditions can also contribute to obesity in a cyclic manner. Family physicians being the initial point of contact for various psychiatric illnesses such as depression, anxiety, eating disorders, and body image distortion emphasizes their pivotal role in obesity management. Primary care physicians, who can significantly contribute to the treatment of obesity, can also play a crucial role in preventing mental health disorders that may be alleviated through obesity management.
Infantile Colic: Diagnosis and treatment options in Primary Care
Authors: Yılmaz Özge Nur
Published: August 2024

Infantile colic (IC) is a condition that can be defined as unexplained episodes of crying/restlessness in otherwise healthy infants. Symptoms typically begin in the first few weeks after birth and usually decrease within three months. Studies have shown that the presence of colic can lead to both short-term and long-term negative outcomes for maternal and infant health. Recognizing colic at the primary care level is possible and necessary, with a prevalence known to range between 10-40% in all infants. Although the exact etiology remains unclear, understanding theories related to the cause of colic can help clinicians to make more accurate decisions in the diagnosis and treatment process. In the differential diagnosis, alarm symptoms accompanying crying must be evaluated, and referrals should be provided when necessary. While there is no definitive cure for infantile colic, some coping methods have shown to be beneficial in reducing the severity of episodes. Parents of infants who meet diagnostic criteria for colic should be informed about the temporary nature of colic and possible treatment strategies. It is important for primary healthcare providers and families to manage the situation as a team during this process.

Digital revolution powered by COVID-19? An analysis of the digitalisation activities of Hungarian entrepreneurs
Authors: Szennay Áron , Csákné Filep Judit
Published: August 2024

Digitalisation presents a significant challenge for small- and medium-sized enterprises (SMEs), as they generally lack the required competencies and qualifications for a digital transformation. However, crises such as the COVID-19 pandemic have highlighted how digitalisation can improve SME efficiency and unlock new markets. This paper aims to contribute to the empirical literature by analysing the factors influencing Hungarian entrepreneurs' activities and attitudes towards digitalisation during the COVID-19 pandemic. The results are based on the quantitative analyses of Hungarian datasets of the Global Entrepreneurship Monitor (GEM) spanning 2021 to 2023, complemented by figures from a representative survey of SMEs in 2022. Our findings show that while nearly all SMEs utilise digital devices, adopting more advanced solutions remains low. Although the pandemic somewhat accelerated the digitalisation efforts, most entrepreneurs do not expect to use more digital solutions in the next six months. There is no consistent correlation between digitalisation and entrepreneurial motives, as the cluster analyses did not provide homogenous groups of entrepreneurs in the years analysed, so we can conclude that digitalisation efforts may be even among them. Thus, to overcome the challenge of digitalisation, policymakers should incentivise entrepreneurs to improve their digital skills and implement digital solutions.
Epistemologi dan Pendekatan-pendekatan Hermeneutika Hasan Hanafi
Authors: Anshory Ali Ridwan , Salsabila Hanna
Published: August 2024

This research aims to explore Hasan Hanafi's hermeneutics in interpreting the Al-Qur'an through a liberation and emancipatory interpretation approach. Hasan Hanafi wants to describe humans in their capacity as humans, involving linguistic, historical, social and geographical aspects. Hanafi's motivation comes from concerns about the crisis of interpretive orientation and the weakening of epistemological reasoning. By combining phenomenology, Marxism, Ushul Fiqih, and hermeneutics, Hanafi created a practical hermeneutic theory to provide solutions to the problems of Muslims, creating a normative-ideological basis for fighting repression, exploitation, and injustice. The recommendation from this research is to continue further research regarding Hasan Hanafi's practice of interpreting the verses of the Al-Qur'an.

Modification of the intensity of evaluation as an interactional resource
Authors: Hayano Kaoru
Published: August 2024

Using the methodology of conversation analysis, this study considers excerpts from Japanese spontaneous conversation in which the intensity of evaluation is modified through self-repair operations. It demonstrates that the modification is utilised as an interactional resource. The analysis reveals that the intensity of evaluation is modified to achieve two interactional outcomes: to disambiguate or amplify the speaker’s evaluative stance toward the referent and to display the speaker’s orientation to the lack of direct epistemic access or strong commitment to the position. The findings are discussed to explore the possibility that the public process of modifying the intensity of evaluation may itself be an interactional resource with which to display the speaker’s dual orientations. The paper further considers the possible crosslinguistic relevance of the findings.

Published: August 2024

The results of experimental studies carried out in the course of research tests of a demonstrator of a sequential hybrid powertrain based on a VK-100-1MK gas turbine engine are presented. It is shown that the presence of a battery provides a smoother change of the gas turbine engine mode and, therefore, an increase in the resource indicators of the latter by reducing the gradients of the temperature field in the hot section parts during transients. A model cycle of operation was developed for the demonstrator of a sequential type hybrid powertrain. A consistent increase in the mechanical load on the output shafts of electric motors was carried out according to this cycle. A study was carried out of the joint operation and mutual influence of the regulators of a gas turbine engine and the battery charge-discharge unit with different values of the coefficients in these regulators: from “maximally soft” (corresponding to the minimum values of the coefficients of the proportional-integral regulator) to “maximally hard” (corresponding to the maximum values of the coefficients proportional-integral controller). The influence of the values of the tuning parameters of the battery charge-discharge unit and the load characteristics of the electric generator on the operation of the energy conversion and distribution system of a sequential hybrid powertrain is shown. The necessity of implementing an algorithm for active voltage rectification in hybrid powertrains of sequential type to ensure the operation of a gas turbine engine in the entire range of modes and increase its resource indicators is deduced. A calculated assessment of the increase in the resource indicators of the main parts of the VK-650V gas turbine engine as part of a sequential hybrid powertrain was carried out: the increase in the cyclic durability of the compressor turbine disk is 12 %, the disk of the free turbine is 163 %.

Published: August 2024

The relevance of the study is due to the tightening of the norms of the International Civil Aviation Organization ICAO on aircraft noise on the ground. Since 2018, for medium-haul aircraft weighing up to 55 tons, noise level requirements are becoming stricter by 7 EPN dB, and most foreign and none of the Russian-made aircraft currently in operation do not meet these standards. In this regard, the competitiveness of domestic civil aviation in the global market is at risk. To solve the problem, a serious intensification of efforts is required in the development of approaches for the design and manufacture of sound-absorbing structures for new generation aircraft engines. High requirements are put forward for sound-absorbing structures for lining the walls of the channels of aircraft power plants: they must have a minimum thickness and weight, withstand high pressures and temperature fluctuations, resist blowing at high gas flow speeds and, of course, have a high sound-absorbing ability. It requires the development of new technologies and equipment for the technologies of widespread filler structures, such as honeycomb, tubular, folded, have been worked out, but have their drawbacks. Within the framework of this article, two design and technological solutions for sound-absorbing structures with a cellular filler have been developed. A comparative analysis of the technological processes for the manufacture of cellular fillers has been carried out. Manual and automated manufacturing technologies and equipment for the manufacture of cellular soundabsorbing structures have been developed. Technological experiments have been carried out to analyze the temperature effect on model samples made of fiberglass prepreg. The minimum time of temperature exposure to model samples has been determined, which ensures a minimum degree of curing. The dependence of the enthalpy of the reaction, the degree of transformation of fiberglass prepreg samples on the heating time is obtained. The design and method of obtaining a cellular filler have been developed.

Authors: Siregar Kardina Engelina
Published: August 2024

Understanding Islamic aqidah plays an important role in shaping the identity and values of Muslims, especially in the educational context. This research aims to explore the influence of religious studies in deepening understanding of Islamic faith and its implications in the educational context. Through careful analysis of the literature, we investigate how the study of religion can be an enriching lens for understanding Islamic creeds. Our findings reveal that the study of religion not only provides an understanding of the theological aspects of aqidah, but also provides insight into the history, culture, and social context that shapes that understanding. The implication of this research is the development of a holistic educational approach, enabling students to integrate knowledge about Islamic creeds with a broader understanding of religion in general. By emphasizing the values of tolerance, respect for diversity, and intellectual criticism, education based on religious studies can prepare students to face the challenges of the modern world with strong beliefs and a deep understanding of Islamic beliefs. Thus, this research makes an important contribution in enriching discussions about Islamic education that is inclusive and relevant to the times.

Authors: Anwar Muhammad Khoirul
Published: August 2024

Abstract: The return of Indonesian students from Al-Azhar University, Egypt has made a major contribution to the dynamics of Islamic scholarship, including through translation activities of the works of Al-Azhar scholars. This activity is motivated by the motivation to transmit Al-Azhar knowledge which is considered to have the opportunity to be introduced to readers in Indonesia. Ahmad Khalafullah’s work is one of the thoughts of Al-Azhar scholars that received this attention. Through qualitative methods involving literature review, this article explains this phenomenon as the dynamics of Quranic studies. Then an analysis was carried out using Kuntowijoyo’s theory of intellectual history which was seen from three aspects, namely: text, context and influence of thought. This article concludes that the translation of Ahmad Khalafullah’s work in the field of Quranic studies is considered by the translator to have an important contribution to the post-reform Indonesian context, where the floodgates of thought are wide open. The influence of the translation of Ahmad Khalafullah’s work has had an impact on the development of thought in Indonesia within the framework of a progressive thought project in the study of the Al-Qur’an as well as being used as a research object.

Authors: Fail Moh.
Published: August 2024

Taqlid dipahami sebagai dasar hukum dalam Islam. Masyarakat awam yang tidak memiliki pengetahuan dan tidak mampu memahami tentang hukum Islam diperbolehkan bahkan diwajibkan mengikuti pedoman hukum kepada orang ahli hukum dalam Islam (Ulama). Mengikuti perkataan, pendapat dan keyakinannya atau perilaku ibadahnya. Taqlid bisa terjadi karena pertemuan antara orang awam dengan Ulama secara langsung atau penerimaan hukum orang awam dari ahli hukum Islam secara tidak langsung, tetapi melalui orang yang bisa dipercaya kebenarannya.Taqlid digital merupakan redefinisi dari taqlid konvensional dimana orang awam mengambil petunjuk hukum dari ahli hukum Islam secara bertemu langsung (offline) berkembang menjadi pengambilan hukum orang awam dari ahli hukum Islam secara tidak langsung (online ).  Ulama memberikan fatwa dan masyarakat awam mengikuti pendapat dan praktek ritualnya. Era post truth memberikan kemudahan memetik hukum Islam melalui teknologi digital. Mulai obrolan biasa, dialog, diskusi, seminar (bahsul masail) sampai kesepakatan bersama (ijma’). Integrasi agama dengan teknologi digital menguatkan keyakinan masyarakat terhadap kebenaran Islam bahwa yang benar bukan hoax dan hoax bukan kebenaran. Taqlid digital meluruskan (cek fakta) tentang Islam, tentang dasar hukum peribadatan dan meluruskan tentang kebenaran masyarakat dalam bertauhid.

Published: August 2024

O Tratado de Itaipu é um marco na cooperação energética entre Brasil e Paraguai, sendo responsável por uma parcela significativa da energia consumida por ambos os países. Este artigo examina a relevância desse tratado para a evolução do direito internacional, público e privado, especialmente em relação à sua natureza jurídica e aos mecanismos de coordenação normativa que promove. Demonstramos que o Tratado de Itaipu é, mais do que um instrumento de direito internacional regularmente internalizado na ordem jurídica brasileira, cujas normas prevalecem sobre outras normas domésticas em virtude de sua natureza e especialidade, um importante instrumento de gestão da pluralidade normativa subjacente à Itaipu Binacional. Além disso, destacamos a importância do espírito inovador do tratado para fortalecer a cooperação, especialmente em um contexto de desafios climáticos crescentes.

Nowadays, the problem of reducing the time for choosing the most rational strategy of incident response in IT systems is a relevant issue. The paper proposes an approach to automate this procedure based on the integration of decision making theory methods: hierarchy analysis method, payoff matrix method and ranking method. The methods that are correct in terms of the complexity of the procedures performed by the decision maker and do not require large computing power are selected. An example of selection and ranking of strategies of response to incidents in the information system based on the proposed approach is shown and a variant of realization of the automated system for solving the considered problem is proposed.

Bu çalışmada Türkiye’de ekonomik faaliyet dalgalanmaları dinamik faktör modelleri yardımıyla analiz edilmektedir. Sanayi üretimi, istihdam, kur, faiz ve fiyat hareketleri, cari denge ve borsa endeksindeki değişim gibi gözlenen değişkenlerden hareketle gözlenemeyen ekonomik faaliyet tahmin edilmiştir. İki adımlı bir tahmin süreci benimsenmiş ve aylık verilerle 2005 ile 2020 arası dönem incelenmiştir. Temel bileşenler yöntemi ile hesaplanan başlangıç değerleri kullanılarak alternatif filtrelerle nihai faktörler ve faktör yükleri hesaplanmıştır. Bu bağlamda Kalman filtresi ve Kalaba ve Tesfatsion’un esnek en küçük kareler tahmincileri kullanılmıştır. Söz konusu tahmincilerin oldukça yakın tahmin performansları olduğu saptanmıştır. Ekonomik faaliyeti yansıtan fa ktör tahmini, 2008’deki Küresel Krizin ve 2018 Ağustos ayındaki kur şokunun ardından iki önemli daralma meydana geldiğini göstermiştir. 2011 başlarında ekonominin örneklem dönemindeki en yüksek genişleme düzeyine ulaştığı saptanmıştır.

The paper discusses selecting the optimal operating parameters of a device for diagnosing internal combustion engines. A laboratory experiment procedure is developed, the experiment layout being approved. Mathematical planning is used to compile a planning matrix of a three-factor experiment 33. The objects of the study are pneumatic valves, air pressure in a pneumatic system, and the compressed air supply interval in degrees of the crankshaft rotation. The experiment yields data on the camshaft angle after the termination of air supply to an internal combustion engine cylinder as dependent on the variation of the set device parameters. The data are statistically processed, with the calculation of the necessary values of the mean, variance, and coefficient of variation. The verification of the accuracy of the data testifies to the repeatability of the process. The results obtained from the experiment are statistically analyzed to generate regression equations. The study presents 3D surface plots and 2D plots showing the angle of camshaft rotation after the cessation of airflow to the engine cylinder as dependent on the values of variable factors. The analysis of the laboratory experiment results allows us to determine the most efficient design and process parameters of an internal combustion engine diagnostic device. The following parameters of the diagnostic device are determined: a pneumatic valve area of 29.5 to 34.5 mm2, a system pressure of 0.48 to 0.62 MPa, and a compressed air supply interval (in crankshaft rotation degrees) of 140 to 180°, which allows for a camshaft rotation angle of 95 to 110 degrees.
Net- ativismo, memória e arquivos:

Este artigo tem como interesses, refletir sobre as relações de poder historicamente construídas por grupos que dominam espaços sociais e seus desdobramentos na criação da memória oficial, que acaba sendo impactada pelo contínuo processo de marginalização de várias populações. A partir disso, pensamos a memória, os arquivos e o patrimônio a partir de seus potenciais usos, tanto de silenciamento quanto de insurgência de pessoas invisibilizadas. Utilizando como corpus da pesquisa a página SP Invisível, propomos um trabalho de análise das narrativas geradas por esses movimentos sociais do início do século XXI. Procuramos também problematizar a banalização dessa moralidade, inerente ao neoliberalismo, que nos leva a uma autodestruição no âmbito social e ambiental e realizamos esta análise sobre o entrelaçamento das mídias e os movimentos sociais, como parte integrante do processo de aparecimento de corpos tradicionalmente invisibilizados e estigmatizados.

One of the rhetoric slogans in the South African archival arena had been 'taking archives to the people' and the need to transform public archives from a domain of the elite into a community resource through inclusive archives. This slogan was expressed in the early days of democracy to express the belief that the shaping power of archives should be used to promote archives as a tool for reconciliation, social cohesion, and nation building.  Due to limited funding, the euphoria surrounding the slogans has waned, as little action has been taken. This paper used a literature review and visits to the Comrades House Museum to explore the possibility of transforming archives by including silenced voices in national archival systems, such as athletic memories from running events such as the Comrades Marathon. The paper argues that this is possible because South African archival legislation allows for the collection of non-public records valuable to the country in order to fill gaps that stem from the colonial era. The paper recommends that archival institutions in South Africa consider incorporating memories of athletes, particularly winners of marathons such as the Comrades Marathon, to take a step towards inclusive memory. In this regard, even if the Comrades Marathon Association collects and digitises such memories in the form of photos and other items such running shoes and vests of the winners, the inventory can be incorporated into the national archival portal that is accessed via AToM. This may allow the collection to be made freely available under a Creative Commons licence. In this regard, accessibility could be greatly simplified and extended to users all over the world. Finally, archival repositories should begin collecting memories of international events held in South Africa, such as the 1999 All Africa Games, the 1995 Rugby World Cup, and the 2010 FIFA World Cup. Records of such events can be gathered from government offices and individuals in order to build and supplement the country's archives. As a result, the country will take a step towards inclusive archives, and more people may be interested in archives as the holdings reflect diversity.

Este artigo aborda os esforços envidados pela administração pública da Guiné-Bissau, em parceria com órgãos públicos e universidades de Portugal e Brasil, para criar legal e legitimamente o arquivo nacional do País. O objetivo é apresentar um resultado parcial do Projeto de Preservação e Conservação do Patrimônio Histórico Documental da Guiné-Bissau, com o apoio financeiro do Programa das Nações Unidas para o Desenvolvimento (PNUD), por meio do Fundo de Consolidação da Paz na Guiné-Bissau. Trata-se da promoção de um curso de formação e capacitação de técnicos e agentes que atuam na gestão de arquivos e documentos da administração pública na Guiné-Bissau, desenvolvido por professores do Brasil e de Portugal. A metodologia utilizada consistiu em um relato de experiência, descrevendo e explicando o contexto histórico, geográfico e institucional dos arquivos públicos da Guiné-Bissau, os objetivos propostos pela experiência, seguido  de uma análise crítica, fundamentada em pesquisa bibliográfica e documental, e na observação e atuação in loco. Os resultados apresentados inferem que há uma extensa agenda de trabalho a ser implementada para que sejam superados os obstáculos para a implementação do arquivo nacional da Guiné-Bissau e das políticas arquivísticas condizentes para a adequada elaboração e aplicação de um programa de gestão de documentos de arquivo no país.
La enseñanza de archivos, Archivología y derechos humanos en Brasil
Authors: Alcides Cougo Junior Francisco Alcides
Published: August 2024

En las últimas décadas, la relación entre archivos, Archivología y derechos humanos ha sido un tema frecuente en trabajos técnicos, publicaciones y eventos, tanto en Brasil como en el extranjero. A pesar de la expansión de este tema en el campo, su incidencia en la enseñanza del área sigue siendo baja. Considerando este panorama, este ensayo tiene como objetivo analizar la presencia o ausencia de contenidos y componentes curriculares relacionados con los derechos humanos en los cursos de Archivología en Brasil y sus intersecciones. El ensayo se basa en un conjunto de provocadoras preguntas sobre el tema: ¿por qué enseñar derechos humanos en cursos de Archivología? ¿Cómo abordan los cursos de Archivología en Brasil el tema de los derechos humanos? ¿Cuáles son los desafíos para la enseñanza de archivos, Archivología y derechos humanos? ¿Y cuáles son sus perspectivas? A partir de las reflexiones en torno a estas preguntas, el ensayo busca contribuir a los debates siempre necesarios sobre la estructura y reforma de los proyectos pedagógicos y curriculares de los cursos de Archivología en el país.
