Authors: Ahmad Nur Azfahani , Mohd Hussain Nur Huzeima , Osman Abd Talib , Abdul Rahim Fiza
Published: May 2024

The extensive reliance on conventional electricity from fossil fuels has heightened dependence in Malaysian communities, but escalating costs, CO2 pollution risks, and the depletion of fossil fuel resources signal its unsustainability. This study investigates the potential of solar PVs to shift rural communities away from fossil fuel-dependent electricity, aiming to foster self-sufficiency. The objective is to enable Malaysian rural communities to benefit from solar technology through a communal-sharing concept. A purposive sampling case study in central Perak reveals that solar energy applications offer communities sustainable electricity access. This approach addresses underutilised roof spaces in Malaysian communities, creating a model for sustainable, resilient living with self-sufficient electricity. Results show successful implementation, with a public building supplying solar-generated electricity to two houses and acting as community storage with a power system of 2 kWp for 24 hours. Illuminance levels improved by 50% to 80%. Town planners and engineers' support is crucial for nationwide dissemination, aligning with the 11th and 12th Malaysia Plan goals for sustainable electricity provision. This effort contributes significantly to achieving national development objectives focusing on providing sustainable electricity for the people.

Published: May 2024

Housing fulfils a person's physical, psychological, social, and economic needs. Housing choices are made by maximizing satisfaction with the home by focusing on various factors, whether external or internal and this varies between generations (i.e. Baby Boomers, Generation X, Generation Y) or by age group. As age increases, an individual's needs and preferences also change due to the ageing factors. This study aims to identify the Malaysian generational Ageing in Place (AIP) housing decision. AIP refers to a person's preference to remain in the same place for as long as possible, which links to their sense of attachment towards a place. This study also aims to provide an overview of the AIP decision-making preferences of the generations in Malaysia. Thus, the objectives of this study are: (i) To identify the factors influencing AIP housing decisions and (ii) To determine the generational AIP decision-making by the generations in Malaysia with Johor Bahru, Johor as the case study. This study adopted a mixed methods of research strategies (qualitative and quantitative). The main findings revealed four (4) main ageing in place preferences such as (1) Economics, (2) Help and Support, (3) Dwelling characteristics, and (4) Neighbourhood. The findings are significant to the public and private sectors in understanding the housing consumers better. The in-depth information gained will help narrow the demand and supply gap between housing consumers and housing providers.

Authors: Sodikin Sodikin
Published: May 2024

Pariwisata halal beberapa tahun terakhir telah menjadi perbincangan di Indonesia. Sejumlah kalangan masyarakat di Indonesia mengira bahwasannya adanya konsep pariwisata halal yang ada di Indonesia adalah sebuah representasi dari pariwisata islami ialah perihal yang agak aneh. Konsep pariwisata halal atau sebutan lainnya seperti dalam istilah lain tamasya syariah yang saat ini memunculkan sebuah perbincangan, apakah konsep pariwisata halal tersebut mempunyai landasan filsafat yang erat pada ajaran Islam, ataukah hanya sebuah wujud rencana ekonomi guna menerapkan pariwisata yang dapat bersaing serta dapat mengembangkan penerimaan dari para wisatawan muslim asing. Penelitian ini dilaksanakan dengan menggunakan metode penelitian kualitatif berdasarkan studi kepustakaan. Hasil penelitian ini menunjukkan bahwa konsep pariwisata halal di Indonesia telah menjadi konsep yang tepat dan sesuai dalam merepresentasikan pariwisata yang islami. Namun di beberapa sisi masih terdapat adanya ketidaksesusaian dalam tata kelola pariwisata halal di Indonesia yang telah mengabaikan prinsip maqashid syariah. Adanya kebijakan legal yang mengadopsi prinsip dan nilai-nilai dalam maqashid syariah adalah hal yang harus dipertimbangkan oleh pemerintah untuk dapat diimplementasikan dalam pariwisata halal di Indonesia.

Authors: Wang Rui , Liu Guangtian , Jing Liwei , Zhang Jing , Li Chenyang , Gong Lichao
Published: May 2024

BACKGROUND

The population is constantly aging, and most older adults will experience many potential physiological changes as they age, leading to functional decline. Urinary and bowel dysfunction is the most common obstacle in older people. At present, the analysis of pelvic floor histological changes related to aging has not been fully elucidated, and the mechanism of improving intestinal control ability in older people is still unclear.

OBJECTIVE

The purpose of this study is to describe how the finite element method will be used to understand the mechanical characteristics of and physiological changes in the pelvic cavity during the rehabilitation process, providing theoretical support for the mechanism for improving urination and defecation dysfunction in older individuals.

METHODS

We will collect magnetic resonance imaging (MRI) and computed tomography (CT) data of the pelvic cavity of one male and one female volunteer older than 60 years and use the finite element method to construct a 3D computer simulation model of the pelvic cavity. By simulating different physiological states, such as the Valsalva maneuver and bowel movement, we will verify the accuracy of the constructed model, investigate the effects of different neuromuscular functional changes, and quantify the impact proportions of the pelvic floor muscle group, core muscle group, and sacral nerve.

RESULTS

At present, we have registered the study in the Chinese Clinical Trial Registry and collected MRI and CT data for an older male and an older female patient. Next, the construction and analysis of the finite element model will be accomplished according to the study plan. We expect to complete the construction and analysis of the finite element model by July 2024 and publish the research results by October 2025.

CONCLUSIONS

Our study will build finite element models of the pelvic floor of older men and older women, and we shall elucidate the relationship between the muscles of the pelvic floor, back, abdomen, and hips and the ability of older adults to control bowel movements. The results of this study will provide theoretical support for elucidating the mechanism for improving urination and defecation dysfunction through rehabilitation.

Feasibility of Multimodal Artificial Intelligence Using GPT-4 Vision for the Classification of Middle Ear Disease: Qualitative Study and Validation (Preprint)
Authors: Noda Masao , Yoshimura Hidekane , Okubo Takuya , Koshu Ryota , Uchiyama Yuki , Nomura Akihiro , Ito Makoto , Takumi Yutaka
Published: May 2024

BACKGROUND

The integration of artificial intelligence (AI), particularly deep learning models, has transformed the landscape of medical technology, especially in the field of diagnosis using imaging and physiological data. In otolaryngology, AI has shown promise in image classification for middle ear diseases. However, existing models often lack patient-specific data and clinical context, limiting their universal applicability. The emergence of GPT-4 Vision (GPT-4V) has enabled a multimodal diagnostic approach, integrating language processing with image analysis.

OBJECTIVE

In this study, we investigated the effectiveness of GPT-4V in diagnosing middle ear diseases by integrating patient-specific data with otoscopic images of the tympanic membrane.

METHODS

The design of this study was divided into two phases: (1) establishing a model with appropriate prompts and (2) validating the ability of the optimal prompt model to classify images. In total, 305 otoscopic images of 4 middle ear diseases (acute otitis media, middle ear cholesteatoma, chronic otitis media, and otitis media with effusion) were obtained from patients who visited Shinshu University or Jichi Medical University between April 2010 and December 2023. The optimized GPT-4V settings were established using prompts and patients’ data, and the model created with the optimal prompt was used to verify the diagnostic accuracy of GPT-4V on 190 images. To compare the diagnostic accuracy of GPT-4V with that of physicians, 30 clinicians completed a web-based questionnaire consisting of 190 images.

RESULTS

The multimodal AI approach achieved an accuracy of 82.1%, which is superior to that of certified pediatricians at 70.6%, but trailing behind that of otolaryngologists at more than 95%. The model’s disease-specific accuracy rates were 89.2% for acute otitis media, 76.5% for chronic otitis media, 79.3% for middle ear cholesteatoma, and 85.7% for otitis media with effusion, which highlights the need for disease-specific optimization. Comparisons with physicians revealed promising results, suggesting the potential of GPT-4V to augment clinical decision-making.

CONCLUSIONS

Despite its advantages, challenges such as data privacy and ethical considerations must be addressed. Overall, this study underscores the potential of multimodal AI for enhancing diagnostic accuracy and improving patient care in otolaryngology. Further research is warranted to optimize and validate this approach in diverse clinical settings.
Empathy Toward Artificial Intelligence Versus Human Experiences and the Role of Transparency in Mental Health and Social Support Chatbot Design: Comparative Study (Preprint)
Authors: Shen Jocelyn , DiPaola Daniella , Ali Safinah , Sap Maarten , Park Hae Won , Breazeal Cynthia
Published: May 2024

BACKGROUND

Empathy is a driving force in our connection to others, our mental well-being, and resilience to challenges. With the rise of generative artificial intelligence (AI) systems, mental health chatbots, and AI social support companions, it is important to understand how empathy unfolds toward stories from human versus AI narrators and how transparency plays a role in user emotions.

OBJECTIVE

We aim to understand how empathy shifts across human-written versus AI-written stories, and how these findings inform ethical implications and human-centered design of using mental health chatbots as objects of empathy.

METHODS

We conducted crowd-sourced studies with 985 participants who each wrote a personal story and then rated empathy toward 2 retrieved stories, where one was written by a language model, and another was written by a human. Our studies varied disclosing whether a story was written by a human or an AI system to see how transparent author information affects empathy toward the narrator. We conducted mixed methods analyses: through statistical tests, we compared user’s self-reported state empathy toward the stories across different conditions. In addition, we qualitatively coded open-ended feedback about reactions to the stories to understand how and why transparency affects empathy toward human versus AI storytellers.

RESULTS

We found that participants significantly empathized with human-written over AI-written stories in almost all conditions, regardless of whether they are aware (t196=7.07, P<.001, Cohen d=0.60) or not aware (t298=3.46, P<.001, Cohen d=0.24) that an AI system wrote the story. We also found that participants reported greater willingness to empathize with AI-written stories when there was transparency about the story author (t494=–5.49, P<.001, Cohen d=0.36).

CONCLUSIONS

Our work sheds light on how empathy toward AI or human narrators is tied to the way the text is presented, thus informing ethical considerations of empathetic artificial social support or mental health chatbots.

Published: May 2024

The Sleman Tourism Office has unveiled Sleman Regency as a sports tourism destination, with one of its offerings being the Sleman Temple Run (STR). The aim of STR is to showcase the potential of Sleman Regency and bolster tourism activities. This study seeks to understand the motivation and behavior of sports tourists participating in the Sleman Temple Run event in 2022. The research methodology involves descriptive quantitative analysis, utilizing both primary and secondary data gathered through questionnaire distribution and literature review. The analysis process includes data examination, grouping, tabulation, and analysis. The findings present participant profiles, an analysis of the motivations of STR 2022 participants, both in general and specific to sports tourism, and the tourism activities they engaged in. Firstly, tourist profiles are delineated based on geographical and demographic aspects. Secondly, the highest general motivation among participants is physiological, while specific motivation related to sports tourism is physical fitness. Thirdly, participant activities predominantly involve trail running, with 62.07% opting for this activity, while 37.93% engage in other activities. From these findings, it can be inferred that while the Sleman Temple Run contributes to increased tourist visitation in Yogyakarta City, particularly in Sleman Regency, the impact may not be significant.
Effect of the Specimen’s Height on the Split-Tensile Strength of the Fibers Reinforced Clay-Lime-Rice Husk Ask Mixture
Authors: Hartono Edi , Muntohar Agus Setyo , Diana Willis , Hemeto Abd. Dzargifar
Published: May 2024

Various studies on the effect of specimen size on splitting tensile strength. However, geotechnical codes lack consensus regarding the recommended specimen diameter and height-to-diameter (H/D) ratio for the split tensile strength test. Hence, it is imperative to study the effect of the height-to-diameter ratio of the specimen on the outcomes of the split tensile strength test, especially for stabilized and fiber-reinforced soil. This research examines the effect of adding lime-rice husk ash and plastic fiber and the effect of specimen size on splitting tensile strength. The height of the specimen is varied, using a height-to-diameter ratio (H/D), namely 0.5, 1.0, 1.5, 2.0, and 2.5, in which the diameter is 70 mm. Two groups of specimens were prepared as stabilized clay without fibers and stabilized clay with 0.1% fibers. The lime required for stabilization is 10% of the dry weight of the soil. In this research, the lime and rice husk ash ratio was designed as 1:1. The splitting tensile strength test was carried out after the specimen was cured for seven days. The investigation indicates that the splitting tensile strength of the specimen without fibers reduces from 217 kPa to 150 kPa as the H/D ratio grows from 0.5 to 2.5. Conversely, the tensile strength of the specimen with fibers increases from 284 kPa to 357 kPa. The findings suggest that the fiber inclusion enhances the splitting tensile strength of the stabilized clay. The specimen size affects the splitting tensile strength, but the effect becomes less noticeable when the H/D ratio exceeds 2.5. From a fracture mechanism perspective, the specimen experiences mode II (shearing) due toa probable “flexural action” along its height. It remains challenging to conclude the dimensions of the test specimen or, at the very least, estimate the correction factor for the size-to-tensile strength ratio.

Authors: Liu Juncheng , Wang Ruei-Yuan
Published: May 2024

In the past two decades, with rapid urbanization and economic development, the land use structure of Lushan City has undergone significant changes, posing challenges to ecological security and food supply. It is necessary to explore its spatiotemporal dynamics and driving factors to optimize land management. This study is based on land use data from 2000 to 2020 and uses GIS to analyze the spatiotemporal changes and transfer status of land use types. The main method is to use the land use transfer matrix and the single land use dynamic degree to study the land use change and its driving forces. The results indicate that the land use change in Lushan City is characterized by the conversion of arable land into construction land and the conversion of wetlands into water bodies. The area of arable land and wetlands has significantly decreased, while construction land and water bodies continue to increase. From the perspective of spatial distribution, the increase in construction land is concentrated in the central part of Lushan City. The driving factors of land use change in the city include the policy of returning farmland to forests and lakes, rapid economic development, changes in population, and the continuous promotion of the tourism industry.

A Comparative Study of G+10 Structure with Various Materials Masonry, Concrete and Glass Fiber Reinforced Gypsum Panel (GFRG)
Authors: Jaiswal Saurabh
Published: May 2024

Abstract: Glass fiber reinforced gypsum plasterboard (GFRG) is an environmentally friendly product. They are made of modified plaster and reinforced with fiberglass strips. Its main use is in the construction of walls, but it can also be used in combination with reinforced concrete on floors and roofs. The panels have voids that can be filled with concrete or reinforced with steel bars to increase strength and ductility. These panels can be used as an alternative building material to replace bricks and concrete blocks. IIT Madras has conducted several research studies and developed a structural design manual for designing buildings constructed by GFRG. Phosphor gypsum is a by-product of the fertilizer industry. In addition to its use as a fertilizer, building material, and soil stabilizer, approximately 85% of phosphor gypsum is disposed of near phosphate plants, which require large disposal sites. Phosphorus from gypsum can be effectively removed by creating glass fiber reinforced gypsum plasterboard (GFRG), also known as fast wall. They may or may not be used as support structures. In this research work we design three different models of G+10 in 5th zone of earthquake as on IS code. The lateral load such as earthquake is to be classified as live horizontal forces acting on the structure depending on the structure’s geographic location, height, shape and structural material. In this study, a multi-story Glass fiber reinforced panel and Brick-infill and concrete block infill wall building has been shown and performed by using software ETABS constructed on a plan ground having G+10 stories.

Feedbacks: A new synthesis of causal loops across ecology
Authors: DeAngelis Donald , Xu Linhao
Published: May 2024

Feedbacks are the basic linkages of living systems. In living organisms,
feedbacks regulate the processes of growth and homeostasis, as well as
their interactions with their world. Feedbacks are equally important in
ecological systems, which is why ‘feedback in ecology’ gets more than 2
million hits on Google. The ecological literature is rich in papers
dealing with the role of feedback in various phenomena. However,
attempts to embrace the subject of feedbacks as a whole in ecology are
rare. Pichon et al. (in press) has done that, with skill and
comprehensiveness. The paper succeeds in bringing the array of different
types of feedbacks into a manageable order that makes this a valuable
synthesis of the subject.
Matrix theory over ringoids
Authors: Rezaei Akbar , Kim Hee , Borzooei Rajab , Saeid Arsham
Published: May 2024

We will study the notion of right distributive ringoids over a field which
are neither rings, semi-rings, semi-hyperrings nor near-rings. Matrices over
ringoids are defined, and new concepts such as top-row-determinate and
down-row-determinate related to 2 ? 2 matrices over a ringoid are
introduced. Moreover, we investigate the notions of the (strongly, (very-)
weak) orthogonality of vectors over a ringoid. Beside, we discuss the notion
of incident vectors and define the concept of ??K-sphere on a ringoid, where
K is a field and investigate some of their properties. Finally, we show that
in a commutative ringoid all of the vectors are strongly orthogonal.

Authors: Gustafsson Amandus , Rölfing Jan D , Palm Henrik , Viberg Bjarke , Grimstrup Søren , Konge Lars
Published: May 2024

Background and purpose: Orthopedic trainees frequently perform short antegrade femoral nail osteosynthesis of trochanteric fractures, but virtual reality simulation-based training (SBT) with haptic feedback has been unavailable. We explored a novel simulator, with the aim of gathering validity evidence for an embedded test and setting a credible pass/fail standard allowing trainees to practice to proficiency.Patients and methods: The research, conducted from May to September 2020 across 3 Danish simulation centers, utilized the Swemac TraumaVision simulator for short antegrade femoral nail osteosynthesis. The validation process adhered to Messick’s framework, covering all 5 sources of validity evidence. Participants included novice groups, categorized by training to plateau (n = 14) or to mastery (n = 10), and experts (n = 9), focusing on their performance metrics and training duration.Results: The novices in the plateau group and experts had hands-on training for 77 (95% confidence interval [CI] 59–95) and 52 (CI 36–69) minutes while the plateau test score, defined as the average of the last 4 scores, was 75% (CI 65–86) and 96% (CI 94–98) respectively. The pass/fail standard was established at the average expert plateau test score of 96%. All novices in the mastery group could meet this standard and interestingly without increased hands-on training time (65 [CI 46–84] minutes).Conclusion: Our study provides supporting validity evidence from all sources of Messick’s framework for a simulation-based test in short antegrade nail osteosynthesis of intertrochanteric hip fracture and establishes a defensible pass/fail standard for mastery learning of SBT. Novices who practiced using mastery learning were able to reach the pre-defined pass/fail standard and outperformed novices without a set goal for external motivation.

Heart disease is a significant health concern globally, and the ability to predict and diagnose it accurately is crucial for effective treatment and prevention strategies. Machine learning algorithms have shown promise in enhancing the prediction of heart disease by analysing complex medical data. So in this paper, we have analysed and compared different machine learning algorithms like Logistic Regression, SVM and Naive Bayes(Gaussian Naive Bayes) for the prediction of heart disease. In proposed work the data used consist of different medical attributes like age, heart rate, chest pain type, restingBP, max heart rate, etc. To increase the accuracy of the models I used cross validation technique (Kfold). The Support vector machine received highest accuracy as compared to other approaches.
The Concept of Creative Capital: from Elitism to Universality
Authors: Melenkin Vladislav L.
Published: May 2024

Development of the creative capital concept and its increasing importance in the modern context are investigated. It is emphasized that the creative capital, which integrates creative and innovative thinking of a person, is becoming a pivotal factor in forming the present-day economy. The evolu-tion of this concept was traced — from assigning the creative abilities to a narrow stratum of the creative class to recognising a fact that any person can possess them, provided they are appropriately developed, including with the aid of the digital technologies. It is emphasized that creation of such spaces as CreaTech, which ensure cohesion of creativity and technological advancements, fosters the formation of creative capital and innovative development

HR Management und Mutterschaft
Authors: Dietz Susanne , Kugler Peter
Published: May 2024

Unternehmen konnten in jüngster Vergangenheit im Personalbereich viele Problemfelder nicht beseitigen: Der Fachkräftemangel, der bereits vor Jahren mit erhobenem Zeigefinger prognostiziert wurde, hält inzwischen Einzug in nahezu allen Fachbereichen und Branchen. Employer Branding und War for Talents sind längst keine exotischen Begrifflichkeiten mehr, sondern fester Bestandteil der Unternehmenskultur. Zugleich wird der Ruf nach weiblichen Führungskräften immer lauter.
In diesem Buch wird aufgezeigt, dass die Lösung dieser Problemebenen in der konsequenten Berücksichtigung der weiblichen Fach- und Führungskräfte liegt - und zwar vor, während und nach der Mutterschaft. Es wird aufgezeigt, welche Maßnahmen das Personalmanagement ergreifen muss, um einerseits dem Fachkräftemangel entgegenzuwirken und wie die Frauenquote irrelevant wird. Andererseits kann mit der Beseitigung dieser Personalproblematik der wirtschaftlicher Erfolg durch einen Wettbewerbsvorteil im Personalmanagement erreicht werden.

Literarische Mehrsprachigkeit und ihre Didaktik
Authors: Hodaie Nazli , Rösch Heidi , Treiber Lisa Theresa
Published: May 2024

Wenn auch marginalisiert, stellt literarische Mehrsprachigkeit keineswegs ein randständiges Phänomen der Literatur dar. Vielmehr lässt sie sich in verschiedensten Epochen aufspüren und sie manifestiert sich in vielfältigen sprachlich-ästhetischen Formen. Dabei eröffnen Sprachmischungen, Hybridisierungen und Neuformierungen ästhetische Zwischenräume sowie erweiterte Möglichkeiten der Deutung und Interpretation. Im Fokus dieses Bandes stehen Ästhetiken, Entwicklungen, Formen und Funktionen literarischer Mehrsprachigkeit in Geschichte und Gegenwart, die auch hinsichtlich ihrer didaktischen Potenziale untersucht werden. Neben literaturwissenschaftlichen Perspektiven erörtern die Beiträge insbesondere literaturdidaktische Ansätze, die literarische Mehrsprachigkeit in poetischen Texten ins Zentrum stellen. Dabei werden verschiedene Formen des Inter-, Trans- oder Heterolingualen didaktisch reflektiert und/oder aus einer dominanzsprachkritischen Perspektive für den Literaturunterricht fruchtbar gemacht.
Produksi Pengetahuan dalam Psikologi Berhampiran Budaya
Authors: Supratiknya Augustinus
Published: May 2024

The subject matter of the culturally-turned Psychology is subjectivity. Adopting the postructuralist Lacanian theory of subjectivity, the human subject is the split subject and/or the lacking subject. The dinamics of subjectivity are constituted by the Other’s desire that circulates in the daily life in the form of discourse and affects subjectivity through identification and interpellation. Research in the culturally turned Psychology aims at creating or constructing in the sense of producing (new) knowledge through reading or interpreting phenomena including things, actions, social institutions, social events, various forms of speech including written, visual, oral, and the like, all of which may be treated as social texts in the sense of a world of signifiers that represents certain meanings in the widest sense of the word. Such kind of research may be conceived as a form of cultural criticism; hence it should ultimately create difference or change in the lives of those it serves. Semiotics and discourse analysis are supposed to be the main methodological tools in the culturally-turned Pschology research.

Розгортання науково-технічного прогресу у сучасному світі приводить до швидкого розвитку технологій, які стають дедалі складнішими і наукоємнішими. Відповідно одним з найважливіших питань є підготувати молодь до концептуального розуміння природних явищ та процесів, на яких і базуються сучасні технологічні розробки і винаходи.  Вивчення такої науково-природничої дисципліни, як фізика, у середній школі відіграє ключову роль у формуванні наукової компетентності та критичного мислення учнів. Однак значного поліпшення потребує структура навчального процесу фізичного дослідження на уроках фізики, щоб підготувати учнів до викликів сучасного світу.
Entre homens e livros: a Biblioteca do Itamaraty na gestão do José Maria da Silva Paranhos Júnior (Barão do Rio Branco), 1902-1912

Published: May 2024

O artigo apresenta os primeiros resultados de uma investigação desenvolvida no âmbito do Grupo de Estudos e Pesquisa sobre Patrimônio Bibliográfico e Documental; também é fruto de intenso debate entre os autores. O tema é a Biblioteca Histórica do Itamaraty, instalada na cidade do Rio de Janeiro, Brasil; e vinculada ao atual Ministério das Relações Exteriores. Para essa espécie, do que chamou Matthew Battles, “Bibiografia de uma Biblioteca”, ao estudar, em 2004, a “Widener Library”, objetivou-se deslindar e problematizar, por meio da pesquisa documental, o contexto de sua criação em 1842. A leitura e análise das fontes revelaram a importância de determinados acervos considerados como fundadores, pela força instrumental que imprimiram aos interesses do próprio Ministério, como fez emergir o recorte cronológico desse trabalho, ou seja, 1902 e 1912. Como um dia disse Gabriel Naudé (1600-1653) uma biblioteca sem organização e sem propósito para formação de sua coleção é um mero ajuntamento de livros. Fiando-se nessa premissa, concluímos que durante o período selecionado para este estudo, graças as formas de gestão engendradas por José Maria da Silva Paranhos Júnior, Barão do Rio Branco, livros da BHI passaram a ser instrumentos que subsidiariam processos decisórios da chancelaria, além de adquirir uma face associada à uma unidade de informação.
