Authors: Workneh Zerihun Getaneh , Gebremedhin Ermias K. , Beyene Nathnael A. , Nigatu Nathnael M.
Published: August 2023

A water distribution network's crucial feature is providing adequate water to meet the required demand with satisfactory performance. The objective of this study was to evaluate the hydraulic performance of the Yeka Abado supply zone in Addis Ababa and suggest corrective measures to the problems obtained through the evaluation. A computer model was created in WaterGEMS to simulate the water distribution network. An intermittent scenario was created based on customer meter data to check the ability of the system to meet the current demand in the study area. Two scenarios were developed to evaluate the system's ability to satisfy the current and future demands in a continuous supply. The model analysis results indicated that pressure below the acceptance criteria at some junctions during peak hours, shortly after the supply, had resumed during intermittent operations. The performance remained satisfactory at other time steps. Furthermore, analysis in a continuous supply scenario for predicted future flows in 2044 indicated that the system is unable to meet the increasing demands in the study area, requiring system expansion works at some point. The results for a continuous supply model for 2021 indicated an excellent performance, with almost all the acceptance criteria being met.
A NON-REFOULEMENT EXCEPTION? AN ANALYSIS OF ARTICLE 33 OF THE 1951 CONVENTION RELATING TO THE STATUS OF REFUGEES IN LIGHT OF THE GENERAL RULE OF INTERPRETATION OF TREATIES
Authors: Haertel Leticia Machado
Published: August 2023

O artigo 33 da Convenção de 1951 sobre o Status dos Refugiados prevê o dever de non-refoulement, proibindo Estados de retornarem refugiados em seu território a seus países de origem. No entanto, ao serem confrontados com influxos massivos de refugiados, algums Estados alegam a existência de um direito de fechar as fronteiras ou, ainda, de retornar os refugiados. O presente artigo discute se a alegada “exceção ao non-refoulement” é permissível perante o Direito Internacional. Para tal, o artigo 33 foi analisado à luz da Regra Geral de Interpretação de tratados prevista na Convenção de Viena sobre Direito dos Tratados. Tal metodologia levou à conclusão de que não há uma “exceção ao non-refoulement” para influxos massivos de refugiados na Convenção de 1951.
CRISE DO ESTADO DE BEM-ESTAR SOCIAL E POLÍTICAS DE AUSTERIDADE NO BRASIL E PORTUGAL: ECONOMIZANDO EM DIREITOS SOCIAIS PARA SOLUCIONAR A CRISE ECONÔMICA
Authors: Erbice De Siqueira Daianne , Schmidt João Pedro
Published: August 2023

O presente artigo possui como tema a implementação de políticas de austeridade como medida de contenção gastos com direitos sociais e estratégia de elevação da economia. O problema de pesquisa questiona: a implementação da políticas de austeridade, com a redução de investimentos públicos em direitos fundamentais sociais e flexibilização de direitos no Brasil e em Portugal, é uma via para a solução para a crise econômica? O objetivo é averiguar se a implementação de medidas áusteras advindas da noção neoliberalista pode ser considerado elemento solucionador da crise econômica no Brasil e em Portugal. O método de abordagem utilizado é o histórico-crítico combinado com o método dedutivo. O método de procedimento é o monográfico e a técnica de pesquisa é bibliográfica e documental. O estudo possui como base teórica autores como Ingo Wolfgang Sarlet, Manuel Castells, Amartya Sen, Robert Alexy e Thomas Piketty. Como principais resultados, verificou-se que a implementação de políticas de austeridade, além de não elevar o crescimento da economia gera o agravamento das desigualdades sociais, já latentes nos países estudados.
DIREITOS HUMANOS E IDENTIDADE DE GÊNERO: O GIRO DECOLONIAL COMO POSSIBILIDADE DISRUPTIVA DOS PARADIGMAS MODERNOS EUROCÊNTRICOS
Authors: Gervasoni Tamiris Alessandra , Bolesina Iuri
Published: August 2023

Com o auxílio da metodologia de abordagem fenomenológico-hermenêutica, métodos de procedimento histórico e monográfico, e técnica de pesquisa por documentação indireta, o presente artigo investiga as consequências do fenômeno da modernidade a partir do conceito de colonialidade nas questões de gênero até a contemporaneidade, com o objetivo de demonstrar as contribuições de uma mirada decolonial como possibilidade disruptiva. Para tanto, inicialmente apresenta a origem e evolução histórica do feminismo, organizado em ondas, o qual desenvolve o conceito de gênero, analisado em segundo momento. Em sequência, aborda-se o conceito de colonialidade e sua constituição histórica a partir da modernidade como projeto de poder instituído de modo eurocêntrico. Compreende-se que, diante do exposto, a perspectiva decolonial sobre as relações de gênero insere aspectos antes desconsiderados como a própria dominação histórica e cultural exercida sobre as identidades percebidas como vulneráveis ou anormais, possibilitando uma possível ruptura com a lógica da naturalização que autoriza e perpetua comportamentos violadores de direitos humanos, ocasionando, ainda que de modo indireto, em incentivo e cultivo de uma cultura de violência de gênero naturalizada.
DO CONSENTIMENTO PARENTAL CONTRÁRIO AO MELHOR INTERESSE E AOS DIREITOS PERSONALÍSSIMOS DA CRIANÇA NA LEI GERAL DE PROTEÇÃO DE DADOS
Authors: Cardin Valéria Silva Galdino , Aparecida Costa Cláudia
Published: August 2023

O estudo tematiza o art. 14 da Lei Geral de Proteção de Dados (LGPD – Lei n. 13.709/2018), especialmente no que tange ao consentimento parental que disciplina a análise de dados do menor realizado em desconformidade com o melhor interesse da criança.  Realizar-se-á uma análise hermenêutica do texto legislativo para evidenciar a ausência de adequação da proteção direcionada exclusivamente à criança e ao adolescente como instrumento necessário ao desenvolvimento da personalidade do menor. Ao final, observa-se que a promulgação da LGPD consagra um importante marco regulatório da internet. Contudo há algumas falhas no texto legal, dentre elas a de uma alternativa capaz de substituir o consentimento parental quando ele afronta direitos e garantias legais do menor. Adotou-se o método de abordagem hipotético-dedutivo, com técnica de pesquisa de revisão bibliográfica e documental.
DIREITO À SEGURANÇA ALIMENTAR SOB A LUZ DE MOVIMENTOS SOCIAIS AGROECOLÓGICOS: PERSPECTIVAS DECOLONIAIS PARA A REALIZAÇÃO DA SOBERANIA ALIMENTAR NO BRASIL
Authors: Iung Izolani Francieli , Angelin Rosângela , Cervi Jacson Roberto
Published: August 2023

O modo de produção agroalimentar estabelecido no Brasil, baseado em monoculturas voltadas à exportação com utilização de agrotóxicos e de transgênicos, pode estar contribuindo para retroalimentar a colonialidade aqui existente, dado que atende aos interesses hegemônicos do Norte Social. Ocorre que esse padrão agrícola tem dificultado a concretização da soberania alimentar e do próprio direito à segurança alimentar. Ademais, tem causado má distribuição e concentração de alimentos nas camadas mais altas, desperdício de alimentos ao longo de toda a cadeia produtiva e impactos socioambientais dos mais diversos, fazendo com que sejam buscadas formas de superar esse paradigma de colonialidade, como os movimentos sociais agroecológicos. Nesse contexto, este estudo tem o objetivo central de compreender esses limites e possibilidades de promoção da soberania alimentar no Brasil a partir de movimentos sociais agroecológicos voltados ao direito à segurança alimentar. Para tanto, utiliza-se o trinômio metodológico, com abordagem sistêmico-complexa, procedimento e técnica, procedimento de pesquisa bibliográfica e técnicas de resumos e fichamentos. Conclui-se que os movimentos sociais agroecológicos constituem-se de alternativas viáveis à libertação da colonialidade que afeta o Brasil, podendo efetivamente gerar um processo emancipatório rumando à almejada soberania alimentar. Todavia, esbarram em alguns entraves, como a essência do direito, os desafios gerados pela financeirização do capital, as tendências reducionistas sobre educação e conhecimento e a própria questão da sociedade capitalista do hiperconsumo.

Published: August 2023

Analisa-se, por meio desse artigo, as implicações do Acordo de Escazú na regulamentação legal da gestão dos recursos hídricos no Brasil, a partir da aplicação da teoria dos sistemas ambientais multiníveis. Para tanto, investiga-se a relevância do Acordo de Escazú, e dos elementos integrantes do princípio da participação na seara ambiental. Verifica-se o trajeto do processo de incorporação formal do Acordo no ordenamento jurídico nacional e as consequências da ausência de ratificação do acordo, que dificulta – mas não impede - a sua inserção na governança judicial multinível. Nesse diapasão, enumeram-se considerações acerca da teoria do direito ambiental multinível ou “sem fronteiras”, a partir da concepção do direito ao meio ambiente como um direito humano. A metodologia envolve pesquisa interdisciplinar, com orientação epistemológica na teoria crítica e congrega teoria e práxis na articulação do Direito Constitucional e Ambiental com as técnicas de análise documental, jurisprudencial e de revisão bibliográfica, diante da imprescindibilidade da governança judicial e da atuação dos stakeholders. Tem-se por resultados esperados, após a confrontação entre a doutrina, legislação e fatos, apresentar argumentos que contribuam para a aplicação dos princípios norteadores do Acordo de Escazú na legítima gestão hídrica, que inclui a composição social e plural dos comités gestores das bacias hidrográficas brasileiras e a respectiva capacitação para este mister.

Exertional Dyspnea; Just an Untrained Child? Two Case Reports
Analyzing the Role of Lung Function Testing
Authors: La Regina Domenico Paolo , Mancino Enrica , Iovine Elio , Spatuzzo Mattia , Virgili Fabrizio , Matera Luigi , Nenna Raffaella , Midulla Fabio
Published: August 2023

Background:

Dyspnea is a common symptom that afflicts many patients with pulmonary
disease and may be the primary manifestation of not only lung disease but also myocardial
dysfunction, anemia, neuromuscular disorders, obesity, etc. Dyspnea can be induced by physical activity,
which is referred to as exercise-induced dyspnea (EID). It can be caused by various etiologies,
sometimes concomitant. In pediatrics, the three most common causes of exertional dyspnea
are exercise-induced bronchoconstriction, inducible laryngeal obstruction, and being physically untrained

Case presentation:

We report two cases of adolescents who developed EID and their management
approach. The first patient had an inducible laryngeal obstruction (EILO), while the second had an
exercise-induced bronchoconstriction (EIB).

Discussion:

The diagnosis of EIB is based on clinical symptoms (e.g., exercise-related symptoms
of dyspnea, cough, or wheezing) and lung function testing (LFT). This test shows a reversible airflow
limitation in response to exercise. A decrease in FEV1 ≥ 10% is considered positive. A major
goal is to ensure that patients with EIB continue physical activity. Therapy is based on non-pharmacologic
and pharmacologic measures.

Conclusion:

Our aim is to add our experience to the available knowledge on the diagnosis of EID.
In conclusion, when faced with a child with exertional dyspnea, before declaring that he is not
trained, it is always necessary to collect an accurate medical history, examination and carry out
LFT, excluding pathologies of the upper and lower respiratory tract, such as EILO and EIB.
Associations between Disordered Eating Behaviors and HbA1c in Young People with Type 1 Diabetes: A Systematic Review and Meta-analysis
Authors: Marks Kevin P. , Aalders Jori , Liu Shengxin , Broadley Melanie , Thastum Mikael , Jensen Morten B. , Ibfelt Else Helene , Birkebaek Niels H. , Pouwer Frans
Published: August 2023

Background:

In type 1 diabetes, disordered eating behaviors (DEB) can adversely impact
HbA1c. Diabetes-adapted DEB questionnaires assess intentional insulin omission, whereas generic
questionnaires do not. Given the number of studies describing DEB-HbA1c associations published
over the past decade, an updated systematic review is warranted.

Objective:

The study aimed to examine the associations between DEBs assessed by generic and diabetes-
adapted questionnaires (and subscales) and HbA1c among young people (<29 years) with
type 1 diabetes.

Methods:

A systematic search was conducted in PubMed, Embase, PsycInfo, and CINAHL databases.
Observational studies examining associations between DEB as assessed by questionnaires
and HbA1c were included. Publication information, DEB and HbA1c characteristics, and DEBHbA1c
associations were extracted. Hedges’ g was calculated for mean HbA1c differences between
groups with and without DEB.

Results:

The systematic search yielded 733 reports, of which 39 reports representing 35 unique
studies met the inclusion criteria. Nineteen studies assessing DEB by diabetes-adapted questionnaires
(n=5,795) and seven using generic questionnaires (n=2,162) provided data for meta-analysis.
For diabetes-adapted questionnaires, DEB was associated with higher HbA1c (g=0.62 CI=0.52;
0.73) with a similar effect size when restricted to validated questionnaires (g=0.61; CI=0.50;
0.73). DEB was not associated with HbA1c for generic questionnaires (g=0.19; CI=-0.17; 0.55), but
significantly associated with higher HbA1c for validated generic questionnaires (g=0.32; 95%
CI=0.16-0.48). Participant and HbA1c collection characteristics were often inadequately described.

Conclusion:

Diabetes-adapted DEB questionnaires should be used in youth with type 1 diabetes
because they capture intentional insulin omission and are more strongly associated with HbA1c
than generic DEB questionnaires.
Role of Sapindus emarginatus Pericarp Extract in Gut Serotonin Level and
its Emetic Activity in Animal Models
Authors: Vivekanandan Lalitha , Thangavelu Prabha , Murugesan Jagadeeswaran , Selvaraj Hemalatha
Published: August 2023

Background:

Emesis is a complex and distressing protective mechanism that helps to
remove toxic substances from the stomach and prevent further ingestion. The emetics and cathartics
are predominantly used for accidental and intentional ingestion of poisons or toxins. The availability and usage of emetics in humans are limited because of their side effects. Therefore, to treat poisoned people, we need effective medications. Sapindus emarginatus Vahl., often called soapnut, is
a member of the Sapindaceae family. They have historically been used as emetic, antipruritic, laxative, antifertility, and anti-inflammatory medicines.

Objective:

This study aims to assess the gut serotonin level and emetic effect of Sapindus emarginatus hydroethanolic pericarp extract (HESE) by using animal models.

Methods:

Gravimetric analysis was used to determine the HESE's saponin content. The emetic effect of the HESE at a dose of 250, 500, 1000, and 2000 mg/kg was evaluated by copper sulfateinduced emesis in the chick model and cisplatin-induced emesis in the rat-pica model. The serotonin level in rat intestinal mucosa was measured by spectrofluorimetry.

Results:

HESE was estimated to contain 11.92% saponin. The extract at high doses of 1000 and
2000 mg/kg showed emetic activity evidenced by increased frequency of retching in chick, increased kaolin intake, and anorexia in the rat-pica model. The extract showed a significant increase
in serotonin levels in the proximal part of the small intestine in comparison with normal animals.

Conclusion:

According to the results of the current investigation, which employed various animal
models, the HESE demonstrated appreciable emetic activity. The extract at a high dose showed a
significant emetic effect due to increased serotonin levels in the gut. The HESE was discovered to
be a strong contender for the treatment of poisoned patients. More research are required to validate
their adverse effects of frequent usage.
Drug Polymorphism: An Important Pre-formulation Tool in the
Formulation Development of a Dosage Form
Authors: Singh Prateek , Sharma Shaweta , Sharma Pramod Kumar , Alam Aftab
Published: August 2023

Polymorphism permits solids to have two or multiple crystal structures with varying
orientations or conformations, and polymorph drug dissolution and solubility vary. Polymorphism
influences drug efficacy, bioavailability and toxicity. Various parameters can
regulate polymorph crystallization, including supersaturation phase, temperature, stirring
rate, solvent addition rate, seed crystal, additives and pH. To characterize and monitor polymorphs,
various analytical approaches are available, including powder X-Ray diffraction /
X-Ray diffraction (PXRD/XRD), also called as Gold Standard method, differential scanning
calorimetry (DSC), Infrared spectroscopy (IR), and microscopical studies. To prevent polymorphic
change during production, distribution, and storage, formulation with the most stable
form in the marketed product is considered. In addition, by monitoring each phase of raw
material processing, polymorphisms can be controlled during dosage form manufacturing.
The objective of this review is to provide concise information on drug polymorphism, their
characterization process, their effect on the stability of dosage forms, factors controlling
polymorphism in the crystallization process, some case studies on polymorphs, control of
polymorphism during the formulation of successful dosage forms and some of the regulatory
considerations regarding polymorphs. Various databases like Pubmed/Medline, Google
Scholar and Web of Science of all English language articles were searched, and relevant
information was collected regarding the importance of polymorphism in formulation development.
From a vast literature survey, it was found that polymorphism is a very important
tool in a pre-formulation study that provides information about the fate of a drug molecule in
its journey. From the present study, it was concluded that the polymorphism property of a
drug should be taken into consideration at the pre-formulation stage since it is a very important
tool for the formulation of a successful dosage form with stability and efficacy.
Tetrazoles Leitmotif: An Intriguing Insight into Contemporary
Developments and Biological Activities
Authors: Mohite Popat , Nahar Deepali , Lonkar Ankita , Kadam Aditya , Desle Kaustubh
Published: August 2023

Heterocyclic compounds with a tetrazole core are of great interest because they represent an important class of synthetic compounds with a wide range of relevant biological properties that have the potential to be clinically translated as treatments for a variety of disorders. Due to their beneficial bioactivities, heterocycles with a tetrazole scaffold have aroused the interest of organic and medicinal chemists and sparked much attention in recent years. Tetrazoles are a form of nitrogen heterocycle found in several natural compounds in addition to their pharmacologically active nucleus. The tetrazole ring is similar to carboxylic acids and acts as a bioisostere analogue. A booster is a set of molecules with identical physiological features, including biological activity. Tetrazole nuclei are found in compounds used to evaluate new antimicrobial, anticancer, antitubercular, anticonvulsant, antimalarial, antihypertensive, and anti-inflammatory medicines. Tetrazole and its derivatives' broad and potent actions have established them as pharmacologically significant scaffolds. So far, tetrazole ring alterations have proven to be highly efficient, with greater efficacy. This review aims to provide an in-depth recapitulation of recent trends used to synthesize promising Tetrazole incorporated compounds and focus on the clinical significance of functionalized tetrazole analogues, which would essentially aid medicinal chemists in new research exploration and discovery in this field.
Current Regulations of Herbal Medicines in the US and EU
Authors: Krishna P. Dheeraj , Gowrav M.P. , Bhaskaran Mahendran , M.R. Kruthika
Published: August 2023

Background:

If a herbal pharmaceutical is intended to impact the function of the human organism, it is categorized as a medication or a nutritional supplement. According to the FDA, the medicine must be offered under a New Drug Application (NDA). The European Medicine Agency (EMA) has established two methods for registering herbal medicals: Under Directive 2001/83/EC, a full marketing authorization (MA) is obtained by submitting a dossier containing data about the quality, safeness, and effectiveness of pharmaceuticals, which include physical and chemical, biological, or microbiological tests, as well as pharmacological, toxicological, and clinical trial documentation; There is a simplest technique under Directive 2004/24/EC for classical herbals that do not needs professional monitoring and where the indication of long history use of pharmaceuticals exists and appropriate relevant journals to illustrate a very well medicinal usage is not provided.

Aim:

A study about the regulatory status of herbal drugs/products was conducted in America and Europe to understand the various classes under which the sale of herbal goods is authorized and their premarketing criteria.

Materials and Methods:

This study has been performed by gathering information from the official websites of the USFDA and EMA.

Results:

A thorough evaluation was carried out in order to identify the impediments to the harmonization of herbal goods.

Conclusion:

Aside from the challenges of herb supply and conservation, it has been shown that there is a lack of uniformity in the regulatory standards of herbal supplements globally. These are impeding international commerce and the expansion of the herbal goods market. USFDA classifies botanical items as pharmaceutical, nutrition, or dietary supplement based on the indications or ultimate use.

Authors: Subhan Iqra , Siddique Yasir Hasan
Published: August 2023

:

Hesperidin is a major flavonoid in sweet oranges and lemons. Aglycone form of hesperidin i.e., hesperetin, and their various derivatives possess significant potential as therapeutic agents for a wide range of diseases and disorders. No signs of toxicity have been observed with the normal intake of hesperidin or related compounds. Hesperidin has been reported to possess a wide range of pharmacological properties, which includes antioxidant, anti-viral, anticancer, antidiabetic, analgesic, organ protective, neuroprotective, antihypertensive, and cardioprotective effects. This needs to be effectively studied at the clinical level so as to firmly establish the usefulness of these compounds in the treatment or prevention of disease in humans. This paper reviews various aspects of hesperidin, including their chemistry, biosynthesis, and bioactivity.

Published: August 2023

Introduction:

Electrowetting has become one of the most widely used phenomena for
utilizing miniature contents of liquids on surfaces.

Method:

Electrowetting is an effective way to modify the droplet’s form with an electrical field. In
this work, we will review some basics of electrowetting fundamentals and details of electrowetting
on dielectric (EWOD) structures and materials. The principle of electrowetting liquid lenses and
their particular configurations have been demonstrated.

Result:

It should be noted that electrowetting lenses are better for commercial use because they use
an electrical drive instead of a mechanical approach.

Conclusion:

After a brief look at the simulation methods, the electrowetting lens and the COMSOL
simulation of a model are focused for this sort of electrowetting application. Some crucial
criteria are compared to distinguish the appropriate situation and materials.
Critical Thinking and Problem Solving: Employers’ Predilection for Plum
Jobs
Authors: G.J. Chithiraimaindan , Marimuthu Mohana , Sekar V.
Published: August 2023

Gone are the days when the purpose of higher education was the pursuit of knowledge at a higher level for deeper understanding. In-depth knowledge fosters a greater understanding of the real world, which in turn promotes science and technology for decent living and eventually for the betterment of mankind. Education to fetch a good job, preferably plum jobs, has become the order of the day, but the percentage of students, who construe education for jobs with attractive salaries, has consistently been high in the decent decade, more pronounced after the onset of globalization in India since the early 1990s. Employers prefer a problem solver, and all they (employers) expect is not to rush to make decisions based on impulses. Almost, problem-solving has become an unwritten tacit job description. It is in this context that there is a need to dwell upon the expectations of employers, not only in business companies but also across all sectors. Critical thinking and problem-solving are the major skills that are expected of candidates for reasons better known to employers, but still, there is an academic interest in terms of understanding the concepts and illustrations of critical-thinking and problem-solving skills. To fill this gap, it is recommended to have the students get educated in their early stage of education. Hence, an attempt is made in this paper to bring to light the nuts and bolts of both (i.e., the detailed practical aspects of critical thinking and problem-solving) to enlighten the students, educational trainers, and academicians. The real challenge lies in transpiring the pedagogy of critical thinking and problem-solving to students and the prospective employees of different companies of all sectors of the economy.

Authors: Bonaccorsi S.
Published: August 2023

Abstract. Due to the increasing number of deep space missions in the following years, the focus on methods and strategies that enable a spacecraft to perform critical operations autonomously is becoming crucial. In the context of cislunar space, this research aims to investigate state estimation methods for such a highly nonlinear dynamics environment in order to identify the best operational scenarios and constraints that enable accurate performance for autonomous spacecraft navigation. In particular, the LiAISON navigation method is considered in the context of a formation of satellites moving in cislunar space exploiting the presence of other cooperative satellites to exchange inter-satellite signals to get range measurements.

High-fidelity simulation of a supersonic parachute for Mars descent
Authors: Placco L.
Published: August 2023

Abstract. The project aims to characterize the unsteady dynamics of the parachute-capsule in a supersonic flow during the descent phase on planetary entry. Presently, Large-Eddy Simulation in combination with an Immersed-Boundary Method is employed to analyze the time-evolving flow of a rigid supersonic parachute trailing behind a reentry capsule during the descent phase through Mars atmosphere. The flow is simulated at Ma = 2 and Re = 106. A massive GPU parallelization is employed to allow a very high fidelity solution of the multiscale turbulent structures present in the flow that characterize its dynamics. We show how the interaction of wake turbulent structures with the bow shock produced by the supersonic decelerator induces strong unsteady dynamics. This unsteady phenomenon called ‘breathing instability’ is strictly related to the ingestion of turbulence by the parachute’s canopy and is responsible of drag variations and structure oscillations observed during previous missions and experimental campaigns. The next steps will take into account the flexibility of the parachute.
How space technologies can address the impact of climate change on aeronautic and the aviation
Authors: Valente M.
Published: August 2023

Abstract. Aviation and flight management are strictly influenced by environmental conditions. Greater variability of the climate and the atmospheric phenomena carries greater risks for air navigation and increase cancellations and delay. An increase in the frequency and intensity of storms, torrential rains, hailstorms, fog, wind gusts, and other meteorological events may lead to a reduction in flight times and from a design point of view an increase in the weight of the aircraft, to counteract higher loads in operation. All of this could produce rising management and operational costs, as well as a reduction in profit. The instruments for remote monitoring as satellites, ground stations, and other technologies allow to collect data about several climate parameters such as temperature, humidity, rainfalls, wind patterns, etc. This data could be analyzed to obtain useful information to improve flights managements and airport services. Moreover, Artificial intelligence (AI) can be used to elaborate this information in real-time. This it makes possible to have more accurate forecasts and update the mathematical model for weather forecasting.
Structural modeling of manufacture-induced gaps and overlaps by high-order unified finite elements
Authors: Racionero Sánchez-Majano A.
Published: August 2023

Abstract. Variable stiffness composites present additional tailoring capabilities if compared to classical straight fiber composites. However, the fabrication of these advanced composites leads inevitably to the presence of manufacturing signatures such as gaps and overlaps, which alter the mechanical behavior of the laminated components. In this work, the fundamental frequency of variable stiffness laminates with the presence of gaps and overlaps is studied. The Defect Layer Method is considered for modeling the defects, while the Carrera Unified Formulation is employed to derive the governing equations which will be solved by the Finite Element Method.
Diseñar el pasado y arqueologizar el diseño
Authors: Londoño-Díaz Wilhelm
Published: August 2023

Quisiera empezar estas líneas con dos preguntas que están interconectadas. La primera pregunta: ¿qué nos dice la teoría del diseño sobre la arqueología como un diseño del pasado? Una disciplina que produce libros, y dentro de esos libros, mapas, fotos, con escalas métricas y polícromas, es sin duda un arte de diseño. La segunda: ¿qué dice la arqueología sobre el diseño como una práctica histórica? Una ciencia que produce cosas bellas, funcionales, contemporáneas, con matices retro o vanguardistas, cuyas mercancías circulan por determinados mercados con personas de alto poder adquisitivo, es sin duda una práctica histórica y cultural. No tengo muchas herramientas para expandirme en una revisión minuciosa de las teorías del diseño; de hecho, no tengo ninguna. Así que esta reflexión, en este nivel, sería un mero deslizarse por caminos desconocidos. Desde el otro nivel, conozco un poco mejor qué es la arqueología, algunas de sus teorías, y con ellas podría adentrarme en las aguas del diseño para ver esta práctica como una producción de paisajes del pasado. Advierto al lector que adrede me excuso del teatro de la citación, porque las ideas generales que esbozo hacen parte del acervo analítico de la humanidad. Hablo de cosas generales, y sería injusto centrarlas bajo la hegemonía de la referencia bibliográfica y toda la violencia simbólica que eso representa.

Authors:   Korean Association For Learner-Centered Curriculum And Instruction, Kim YoungHwan , Lee Chae Young
Published: August 2023

Objectives This study aims to analyze research trends related to domestic forest experiences in order to inform future development and research directions.
Methods For this purpose, RISS was searched using a combination of keywords related to ‘experience’ and ‘forest’, and 158 articles were selected, and the number by year, journal & researcher analysis, word cloud analysis, keyword frequency analysis, NTA, and cluster analysis were conducted.
Results Key findings are as follows. The number of relevant articles increased overall, but 1~2 researchers dominated the domestic research, with a significant proportion of publications in early childhood education journals. In the keyword analysis, the research subject was fragmented over time, but overall, “infant” was dominant, and the initially dominant “attitude toward nature” was decreasing, while “ability”, “emotion” were increasing. In the NTA analysis by period, “infant”, “experience” were dominant overall, with “ability” increasing and “attitude” decreasing. The cluster analysis showed different characteristics by period, with three groups in the period 1(2001-2014), three groups in the period 2(2015-2016), and two groups in the period 3(2017-2022). In particular, there was a clustering of ability studies on infants in the period 2, and studies linking infants, activities, and abilities in the period 3.
Conclusions The main conclusions and recommendations are as follows. Although the number of papers is increasing, the number of researchers and research topics needs to be more diverse, and the content of the research needs to be more evenly diversified in terms of forest experience effects, usefulness, and attitudes. In addition, research subjects should be expanded to adolescents, adults, professionals. Also, research that reflects social phenomena is lacking, the needs of the times(technology, safety, forest complex management) should be reflected. As the domestic academia needs a balanced approach, it is necessary to analyze research trends in the field of early childhood education and analyze detailed topics. In addition, the analysis of various foreign forest experience trends and reflective studies based on a more rigorous concept of experiential learning, are requested.

Methods The three measures were employed: (a) Individuality - Relatedness scale, (b) Managing Affect and Differences scale, (c) Romantic relationship satisfaction scale. The subgroup according to the level of individualityrelationship development was identified through cluster analysis, and the effect of individuality-relationship on the opposite-sex relationship was confirmed using a structural equation model.
Results Results indicated, first, that participants were categorized as four clusters: Undeveloped group of individuality and relatedness, Developed group of individuality and relatedness, Partially developed group of relatedness, Partially developed group of individuality. Second, depending on individuality - relatedness each level, different types of conflict management strategies were used and romantic relationship satisfaction was significantly different between four groups. Third, conflict management strategies had mediating effect on the relationship between individuality - relatedness and romantic relationship satisfaction.

Meanwhile, individuality enhances positive conflict management strategies and has a negative effect on romantic relationship satisfaction. Lastly, this study ends with discussion of implications, limitations and suggestions.
Conclusions This study suggest that if people with unbalanced individuality and relatedness development come to the counseling center, they can promote the growth of undeveloped individuality·relatedness and help to maintain healthy relationships by intervening their conflict resolution strategies to increase romantic relationship satisfaction.
