Authors: De la Rosa Escobar Cristian Alejandro
Published: October 2023

Desde el retorno a la democracia, se han presentado en el Congreso Nacional 5 proyectos de ley para crear la figura del Ombudsman en Chile, pero ninguno se ha logrado materializar. Sin embargo, se constata la creación de diversos servicios públicos símiles a la teoría general del Ombudsman para proteger a la ciudadanía frente a vulneraciones de sus derechos focalizados a materias específicas. Este estudio se centra en el funcionamiento de estos servicios públicos que abarcan materias de atención de un Defensor o Defensora del Pueblo, exponiendo el alcance de su gestión y los principales derechos defendidos entre los años 2010 y 2020, presentando una matriz de datos actualizada sobre la defensa de los derechos de la ciudadanía en Chile.
Produce or Not Produce Certified Foods? An Exploratory Analysis from Portugal
Authors: Forte Teresa , Figueiredo Elisabete , Eusébio Celeste , Tibério Manuel Luís
Published: October 2023

The certification of origin and quality of rural provenance foods paves routes of protection and promotion of the products and the territories. While the importance of certification at socioeconomic, policy, and consumption levels has been addressed in previous research, the views of other key stakeholders—the producers—remain somehow underexplored. The present study contributes to this topic by analyzing data from a survey of producers (n=104) working with urban specialty shops located in three Portuguese cities. The sample was examined considering the differences between those who produce certified food products (n=74) and those who do not (n=30). Chi-square tests were used to compare the socio-demographic features, type of products produced and selling venues. Independent samples T-tests were applied to compare the differences between producers’ motivations, perceived challenges, and impacts of the production. Findings indicate that producers of certified products have distinct motivations, and value different aspects of their productions, namely to contribute to sustainable and healthier production and consumption and to the preservation of local and traditional ways of producing. They also perceive more positive economic impacts on rural places of provenance and tend to value more the Portuguese food products’ image.

Authors: Pasqualotto Carina , Coletto Camila , De Menezes Daniela Callegaro
Published: October 2023

The crisis of the agri-food model opens space for discussion around food seeking more sustainable ways of production and consumption. The local markets can help to walk on this way, making the environment more sustainable. Thus, the article aims to analyze aspects related to environmental, social and economic sustainability with food product exhibitors in local markets in Canada and Brazil. Qualitative research was carried out at local markets, in the Concordia Farmers Market (CFM), in the city of Montreal - Canada and in the Mercado de Produção da Agricultura Familiar (FEPRAF), in the city of Júlio de Castilhos - Brazil. Data were collected through interviews and participant observation, and analyzed using content analysis. The results identified aspects related to environmental sustainability (organic and artisanal foods without chemicals and waste reduction), social (local markets generate an opportunity to strengthen relationships between producers and customers, bonds and exchange of information) and economic (appreciation of local products by developing the region's economy).

Abstract.   This research was conducted to see the impact of road sector DAK allocation on regional road conditions, with DAK allocation, the regions will be able to handle road sections so that there will be additional stability of regional roads in the 2015-2019 period. The methodology used in this study uses analysis. The variables in this study were determined to analyze secondary data, while the variables determined were the DAK Allocation for Roads (X) or the independent variable and the dependent variable (Y), based on the research objective, to determine the impact of DAK allocation for the Road Sector with steady road conditions. Regions from 2015 to 2019. The results of the research are not known that the availability of DAK in the road sector has a positive and significant effect on the Stability of Regional Roads, this can be seen from the significant value (0.000) less than 0.05 and t-count (- 5.707) greater than the t-table -2,785. While the linear regression results show the constant (α) = -0.058 means that even though the DAK road allocation variable with road conditions is zero, the constant is still -0.058. The coefficient β (X) = -0.120 means that if the DAK Sector allocation is increased, the road conditions will increase by -0.120. This is because the total allocation tends to decrease while the total length does not experience an increase while the number of DAK recipients continues to increase.

In materia di proprietary estoppel e rimedi equitativi (Guest v Guest)
Authors: Serio Mario
Published: October 2023

Tesi
Il diritto inglese storicamente non si è mai arreso di fronte all’insufficienza dei propri strumenti rispetto alle situazioni della vita pretensive di una risposta che essi non sono in grado di fornire. Per questo la tradizione ha fatto del sistema di equity il propellente per colmare il divario.
È esemplare al riguardo la vicenda dell’“equitable estoppel”, ossia del rimedio diretto ad impedire che si rinneghino promesse, pur prive di natura contrattuale sulle quali il destinatario abbia legittimamente ed onerosamente fondato il proprio affidamento. Quando oggetto del mancato rispetto della promessa siano diritti reali si parla di “proprietary estoppel”.
Questo è il contesto in cui si colloca la sentenza della Supreme Court del 2022 nel caso Guest v Guest, risolto con una stretta maggioranza, in cui si discuteva della natura del rimedio da attribuire al figlio deluso dalla volontà paterna di revocare l’originaria istituzione di erede a suo favore.
La soluzione adottata dalla maggioranza è consistita nell’attribuzione al genitore della facoltà di scelta tra la istituzione a favore del figlio di un trust o l’attribuzione di una somma di denaro da determinarsi di comune accordo o in via giudiziale.
Data l’esistenza di una robusta opinione di minoranza sembra che ci si trovi di fronte ad un precedente meramente interlocutorio.
The Author’s view
The essay explores the many ways through which the decision of judicial cases may be influenced by, or directed at, an attempt of doing “the minimum equity” required by actual circumstances and by conscience.
One of the most typical measures which equity has devised with an aim “to do justice” is constituted by the “equitable estoppel”, aimed at preventing the author of a non-legally binding promise from reneging on it or otherwise revoking it: its denomination changes to “proprietary estoppel” when property is involved.
In 2022 the United Kingdom Supreme Court has decided by a strict majority of 3 to 2 Guest v Guest where a son’s expectation on his father keeping his word of over 30 years to leave him the farm in which he had continually worked for little or no wage was deluded.
The decision, which partly overturned those of the Judge and of the Court of Appeal, left the father with the option between putting the farm into trust in favour of all his children or paying compensation to his son only, calculated (in such a way as to reflect his earlier than anticipated receipt) on a conventional basis or, alternatively, through remitting the case to the first judge.
My submission is that it is doubtful whether the decision will make a reliable precedent due to such a strong dissenting opinion.
La trascrizione effettuata con riserva dal Conservatore dei registri immobiliari dell’atto istitutivo di trust autodichiarato - aspetti notarili (Trib. Catanzaro, 5 aprile 2023)
Authors: Pulvirenti Giuseppa Maria
Published: October 2023

Massima
Il trust autodichiarato è ammissibile in Italia in virtù della ratifica della Convenzione de L’Aja anche alla luce della presenza nell’ordinamento italiano di figure affini quali i vincoli di destinazione previsti dall’art. 2645-ter del codice civile, i quali, al pari del trust auto-dichiarato, non prevedono né la bilateralità dell’atto di istituzione né tantomeno la destinazione “traslativa”. Il trust autodichiarato stipulato in Svizzera non necessita, ai fini della trascrizione in Italia, di legalizzazione, ma solo dell’apposizione dell’apostille, in forza della ratifica da parte di Svizzera e Italia della Convenzione de L’Aja del 1961. L’atto istitutivo di trust autodichiarato avente a oggetto beni immobili può essere trascritto “a favore” e “contro” il disponente.

On the Trusts and Succession (Scotland) Bill: Modernisation and Transformation
Authors: Harris Lauren , Jefferson Emily
Published: October 2023

The author’s view
The proposed reform under the Trusts and Succession (Scotland) Bill seeks to put a certain view of the modern function of trusts law on a legislative footing. It takes significant inspiration from jurisdictions which have a predominantly commercial trust regime. Two types of reform are evident in the Bill. At times it modernises the traditional Scottish trust in line with a commercial functional evolution. However, through the introduction of new parties (the protector and the supervisor) and a new offshore style trust (the private purpose trust), the reform may more accurately be described as a wholesale transformation of the traditional Scottish trust form.
Tesi
La riforma proposta con il Trusts and Succession (Scotland) Bill cerca di mettere su un piano legislativo una certa visione della funzione moderna del diritto dei trust. Si ispira in modo significativo a giurisdizioni che hanno un regime di trust prevalentemente commerciale. Il disegno di legge presenta due tipi di riforma. A volte modernizza il trust scozzese tradizionale in linea con un’evoluzione funzionale commerciale. Tuttavia, grazie all’introduzione di nuovi soggetti (il guardiano e il supervisore) e di un nuovo trust di tipo offshore (il private purpose trust), la riforma può essere più accuratamente descritta come una trasformazione totale della forma tradizionale di trust scozzese.

Sunto
La finanza ha un ruolo primario nell’economia mondiale. I trustee moderni, pertanto, possono dover adeguare la loro attività anche rispetto alla gestione di ingenti patrimoni finanziari e atti di trust che prevedano una finalità di gestione degli stessi non solo di tipo conservativo, ma anche speculativo. Il caso analizzato in questo lavoro riguarda proprio un caso di acquisto di crediti deteriorati da parte di un trustee, la cui realizzazione è stata possibile grazie a un’attenta redazione dell’atto istitutivo di trust e alla nomina di un cotrustee dotato di particolari requisiti che lo hanno qualificato come investitore professionale su opzione.
THE HISTORY AND TRANSFORMATION OF NEURO-LINGUISTIC PROGRAMMING
Authors: KHASANOV Jahongir
Published: October 2023

Neuro-Linguistic Programming (NLP): method of acting on human consciousness and knowledge, linked to an influence at the level of ideology and Ideas about the World concerning the human mind and moral conscience. In many circles of psychologists, there is the conviction of the pseudo-scientific nature of this method or the conviction that its use causes superficial and short-term effects; despite the lack of full support in scientific circles, this notion has already entered the vocabulary of psychology, education, business and various systems of the so-called "self-development", and it continues to be popularized. NLP or neuro-linguistic programming refers to a whole set of techniques (dissociation, reframing) and methods aimed at promoting the personal development of the individual. This article investigates NLP in detail: its principles, its history, its benefits, and the progress of a session.
Unifying 3GPP, ETSI, and O-RAN SMO Interfaces: Enabling Slice Subnets Interoperability
Authors: Habibi Mohammad Asif , YILMA GIRMA , Costa-Perez Xavier , Schotten Hans Dieter
Published: October 2023

This article addresses two architectural challenges associated with managing and orchestrating open radio access network (O-RAN) slice subnets within the service management and orchestration (SMO) Framework. The first challenge involves unifying the components and interfaces of the O-RAN Alliance, Third Generation Partnership Project (3GPP), and European Telecommunications Standards Institute (ETSI) to enhance the capabilities of the SMO Framework regarding the management and orchestration (M&O) of O-RAN slice subnets and their required resources. The objective of this unification is to eliminate ambiguity in the interaction, interworking, and integration of various standards within a unified SMO Framework and to enable it to leverage the latest specifications. The second challenge entails facilitating standard-compliant interoperability among the components of the three modules by proposing two logical functions and their interfaces within the SMO Framework. This interoperability is intended to enable the components and interfaces of the O-RAN architecture to influence the decisions made by the 3GPP and ETSI components and interfaces concerning O-RAN slice subnets. It will also allow the 3GPP and ETSI components and interfaces to improve their capabilities by utilizing the features and services of the O-RAN architecture.

Reliability in Post-Disaster Networks: A Novel Interference-Mitigation Strategy
Authors: Matracia Maurilio , kishk mustafa , Alouini Mohamed-Slim
Published: October 2023

We hereby present a novel interference mitigation strategy specifically designed to enhance the quality of service that a typical terrestrial user equipment (UE) would experience after the occurrence of a calamity. In particular, we devise a novel stochastic geometry framework where the functioning ground base stations are modeled as an inhomogeneous Poisson point process, and promote proper silencing as an effective solution to improve both coverage and reliability (which is usually overlooked in emergency scenarios); in particular, the latter is evaluated by means of the signal-to-interference-plus-noise ratio (SINR) meta distribution performance metric. The derived downlink performances assume Rayleigh fading conditions for all wireless links. The numerical results show insightful trends in terms of both average coverage probability (which is optimized by choosing the best area for applying the silencing strategy) and SINR meta distribution, depending on: distance of the UE from the disaster epicenter (henceforth intended as the center of the area where the BS can be damaged), disaster radius (also referring to the latter area), and quality of resilience of the terrestrial network. The aim of this paper is therefore to prove the effectiveness of proper silencing in emergency scenarios, at least from the coverage and reliability perspectives. 
Unraveling the Adoption Drivers of Fintech in India: An Empirical Analysis
Authors: Josyula Hari Prasad
Published: October 2023

Fintech refers to the innovative use of technology in the provision of financial services and products. Several factors contributed to the exponential growth of fintech in India, including an increase in internet penetration, adoption of smartphone, favourable government legislations, and a dynamic economy. The agenda behind this study is to create a thorough grasp of the variables affecting fintech adoption in India. A study backed by Partial Least Square Structural Equation Modelling (PLS-SEM1) explored how user trust (UT), perceived benefit (PB), perceived risk (PR), and intention to adopt fintech (IAF) are related by analysing primary data collected from a representative sample of students pursuing higher education. As revealed by the results, IAF is significantly influenced by PB, PR, and UT. The level of trust between users moderate the relationship between PR and IAF. In order to foster fintech adoption, foster innovation, and address potential challenges, targeted policies and regulations need to be developed.

On the Peak-to-Average Power Ratio of Vibration Signals: Analysis and Signal Companding for an Efficient Remote Vibration-Based Condition Monitoring
Authors: Aburakhia Sulaiman , Shami Abdallah
Published: October 2023

Vibration-based condition monitoring (VBCM) is widely utilized in various applications due to its non-destructive nature. Recent advancements in sensor technology, the Internet of Things (IoT), and computing have enabled the facilitation of reliable distributed VBCM where sensor nodes are deployed at multiple locations and connected wirelessly to monitoring centers. However, sensor nodes are typically constrained by limited power resources, necessitating control over the peak-to-average power ratio (PAPR) of the generated vibration signals. Effective control of PAPR is crucial to prevent nonlinear distortion and reduce power consumption within the node. Additionally, avoiding nonlinear distortion in the vibration signal and preserving its waveform is essential to ensure the reliability of condition monitoring. This paper conducts an in-depth analysis of the PAPR of vibration signals in VBCM systems, evaluates the impact of nonlinear power amplification on the system performance, and proposes a lightweight autoencoder-based signal companding scheme to control the PAPR to improve power efficiency and mitigate the impact of nonlinear distortion. The proposed scheme employs a lightweight reconstruction autoencoder with a compression-based activation function in the source to compress the vibration signals and avoid increasing the average power of the compressed signal. In the destination, the proposed scheme uses a denoising-expansion autoencoder to expand the compressed signals while minimizing noise enhancement during the expansion process. The experimental results demonstrate the effectiveness of the proposed companding scheme in preventing nonlinear distortion, improving the efficiency of power amplification in the source, and restoring the PAPR characteristics in the destination while avoiding the undesired effect of noise expansion.
Spatial Network-Wide Traffic Flow Imputation With Graph Neural Network
Authors: Sabzekar Sina , Bahmani Rezvan , Ghasemi Masoud , Amini Zahra
Published: October 2023

Traffic data plays an essential role in Intelligent Transportation Systems (ITS) and offers numerous advantages, including efficient traffic control and system performance improvement. However, due to the scarcity of data collection systems, missing data in traffic datasets is inevitable. Therefore, traffic data imputation becomes an essential task. Graph Neural Network (GNN) is a type of neural network that operates on graph-structured data and has shown potential in handling traffic network related tasks such as traffic prediction and traffic data imputation. In this paper, we contribute to the body of knowledge with two aspects. First, we focus on traffic data imputation using solely spatial information. Most of the studies in the literature address spatio-temporal traffic data imputation, which is a distinct task from our research. Second, Since most GNN models operates on node features, we propose an approach to construct node features for nodes in traffic networks, by leveraging available link flows. To investigate the effectiveness of the proposed method, we implement two missing scenarios, random missing (RM) and block missing (BM). We evaluate the performance of the proposed method on three different sized real-world networks: Sioux Falls, Anaheim, and Chicago. The evaluation results demonstrate that GNN models outperform other baselines for most of the missing patterns.

 
Deflection-Penetration Criterion in defect ridden slanted interfaces: A continuum scale study in 2D Fracture Mechanics and 3D printable models
Authors: Reddy Suraj
Published: October 2023

This paper presents a deeper understanding of the effect of interface orientation and varying defect density within the interface on toughness in 2D media. Our study focuses on a pre-deflected crack that has a majority of its length parallel to the line of symmetry in the horizontal direction, with a small deflected region present in the interface, perpendicular to the line of symmetry. We vary the interface orientation at varying angles with 0 2.5, 5, 7.5, 10, 12.5, 15, 20, 25, 30, 37.5, 45, and 50. For all of the theta , we initially create 10 increments of interface properties, and within each of these combinations, we vary the defect densities ranging from 5 defects to 15 defects. Previous results have shown that higher defect densities in the interface region lead to an overall higher material toughness, while in turn making the interface weaker, allowing for cracks to propagate and deflect with the help of the defects. In this paper, we hope to understand 4 main ideas, (i) How do higher interface angle orientations vs lower angle orientations affect the deflection-penetration criterion? (ii) What is the effect of higher variations vs lower variations of defect densities on the deflection-penetration when faced with differing angles? (iii) How do the Elastic Energy and Stress fields react to changes within the angle of the interface? (iv) Can we recreate the computational results with 3D printable models through tensile testing? Overall, it is quiet clear that in terms of material toughness and stress concentration at the crack tip, the higher angle cases are a clear benefit to the toughness of the material; however, when considering the elastic energy and time needed for failure, the lower angled cases showcase a more preferable case.

Towards a New Understanding of Swedish School Reforms: A Sociological Analysis of Textbooks’ Role in Reforms of School Mathematics, 1919–1970
Authors: Prytz Johan
Published: October 2023

This article sheds new light on the Swedish comprehensive school reform implemented in the 1960s (the Grundskolan reform) and the four decades preceding the reform. This reform was typical for the Nordic countries. The presented study concerns reforms in mathematics education and how change was initiated and driven before and during the comprehensive school reform. The analysis has a focus on the role of textbooks in educational governance. The analysis is based on Bourdieu’s field theory and concerns how a new way of preparing and driving reforms of school subjects restructured relationships between the state, textbook producers, and teachers. This article is mainly a synthesis of results from several previous studies on governance of Swedish mathematics education. The analysis reveals not only a new characteristic of the comprehensive school reform (swift and radical rather than slow and successive), but also a bottom-up movement in the school system, which has been commonly understood as top-down, very centralised, and slow moving. The results of the analysis help explain why the Swedish comprehensive school reform gained early acceptance and momentum. Another contribution of this article concerns historical textbook research, particularly regarding how fundamental changes in authorship of textbooks (from visible individual authors to anonymous collectives) can be related to educational governance and changes in power structures.

A análise de fragmentos metálicos em ossos perfurados pode determinar se houve ou não manipulação de projétil de arma de fogo (PAF). As características dos projéteis, como composição química, substâncias e resíduos gerados posteriormente ao disparo, podem contribuir para a elucidação de diversos processos criminais. O objetivo deste trabalho foi investigar a composição química de fragmentos metálicos presentes em perfurações de crânio humano, e relacioná-los ou não a um projétil de arma de fogo. Para esta investigação, utilizou-se análise de espectroscopia de raios-X por energia dispersiva (EDX) para obter a composição elementar semi-quantitativa do material analisado. A composição química dos fragmentos metálicos encontrados em perfurações cranianas foi semelhante à comumente encontrada em PAF, os quais apresentam Pb, Cu, Zn e Fe como elementos majoritários. A análise de EDX é uma técnica conveniente (custo-benefício), relativamente rápida e não-destrutiva, mostrando-se eficiente na discriminação de fragmentos metálicos presentes nos orifícios do crânio humano, sendo possível relacioná-los com disparos de armas de fogo.

A parada cardiorrespiratória (PCR) é uma emergência médica crítica que requer intervenção rápida e eficaz para aumentar as chances de sobrevivência. A Estratégia de Saúde da Família (ESF) desempenha um papel fundamental na promoção da saúde e na prevenção de doenças em comunidades. No entanto, a abordagem da ESF na gestão da PCR ainda é um tópico que merece análise e avaliação. O objetivo desta revisão integrativa é analisar e sintetizar a literatura existente relacionada ao atendimento a pessoas com parada cardiorrespiratória na ESF. Pretende-se identificar as melhores práticas, desafios e impactos da intervenção da ESF nesse cenário de emergência médica. Esta revisão integrativa envolveu a seleção de estudos científicos, pesquisas e artigos relevantes por meio de buscas em bases de dados, como PubMed, Scopus, Lilacs e Google Scholar. Utilizaram-se descritores como "parada cardiorrespiratória", "atendimento pré-hospitalar", "Estratégia de Saúde da Família" e termos relacionados. Foram incluídos estudos publicados nos últimos dez anos em português, espanhol ou inglês. Os resultados dos estudos selecionados foram analisados e sintetizados para identificar as práticas mais eficazes de atendimento a PCR na ESF, bem como os desafios enfrentados na implementação dessas práticas e os impactos observados na sobrevida e na qualidade de vida dos pacientes.  A implementação bem-sucedida dessas práticas pode ter um impacto significativo na sobrevivência e na qualidade de vida das pessoas que vivenciam uma PCR, reforçando o papel crucial da ESF na assistência pré-hospitalar. No entanto, são necessárias pesquisas futuras para aprimorar ainda mais as diretrizes e protocolos relacionados ao atendimento de PCR na ESF, bem como para avaliar seu impacto em longo prazo.

Os distúrbios hipertensivos na gravidez representam uma condição de grande relevância na obstetrícia, sendo uma das principais causas de morbidade e mortalidade materna e fetal em todo o mundo. Essas complicações abrangem desde a hipertensão gestacional, a pré-eclâmpsia até a eclâmpsia, cada uma com características distintas e potencial impacto adverso na saúde da gestante e do feto. Portanto, este estudo tem como objetivo realizar uma revisão integrativa da literatura sobre os distúrbios hipertensivos na gravidez, a fim de compreender suas características, fatores de risco, diagnóstico, manejo clínico e impacto na saúde materno-fetal. Para realizar esta revisão integrativa, foram consultadas bases de dados eletrônicas, como PubMed, Scopus, Lilacs e Google Scholar, utilizando os seguintes descritores: "distúrbios hipertensivos na gravidez", "hipertensão gestacional", "pré-eclâmpsia", "eclâmpsia", "fatores de risco" e "manejo clínico". Foram incluídos estudos publicados nos últimos dez anos, escritos em português, espanhol ou inglês, a fim de abranger as evidências mais recentes relacionadas a essas condições. Os distúrbios hipertensivos na gravidez são uma preocupação significativa em saúde materna e fetal. Esta revisão integrativa da literatura permitiu uma análise abrangente dessas condições, identificando os fatores de risco, as características clínicas, os métodos de diagnóstico e as estratégias de manejo clínico recomendadas. A compreensão desses distúrbios é fundamental para melhorar a prevenção, o diagnóstico precoce e o tratamento, com o objetivo de reduzir a morbidade e a mortalidade materna e fetal associada a essas complicações.

Повышение энергоэффективности зданий и сооружений является первоочередной задачей государства. В статье рассмотрен вариант снижения теплопотерь здания на основе выбора его архитектурно-планировочного решения. Предложен пассивный энергосберегающий метод, обеспечивающий уменьшение расхода энергетических ресурсов на поддержание нормируемых характеристик микроклимата. Определены геометрические параметры эллипсоидального здания с заданным объемом строительства с учётом того, что оно имеет усеченную форму. Рассчитаны трансмиссионные и инфильтрационные теплопотери приведённого сооружения, также величина его жилой площади и площади застройки. Описано сравнение теплопотерь и некоторых технико-экономических параметров зданий одинакового строительного объема сферической, эллипсоидной и традиционной формы параллелепипеда. Все описываемые здания имеют витражное остекление. При сопоставлении полученных расчётным путём данных осуществлён выбор наиболее энергоэффективного архитектурно-планировочного решения рассматриваемых строений.

Improving the energy efficiency of buildings and structures is a priority task of the state. The article considers the option of reducing the heat loss of a building based on the choice of its architectural and planning solutions. We propose a passive energy-saving method that reduces the consumption of energy resources to maintain the normalized characteristics of the microclimate. We determined the geometric parameters of an ellipsoidal building with a given volume of construction, taking into account the fact that it has a truncated shape. We calculated transmission and infiltration heat losses of the given structure, as well as the size of its living area and building area. We compare heat loss and some technical and economic parameters of buildings of the same construction volume of spherical, ellipsoid and traditional parallelepiped shapes. All the described buildings have stained glass windows. When compared the data obtained through calculation, we determined the choice of the most energy-efficient architectural and planning solutions.
