Abstract
Representation is the embodiment of a student's idea of a problem, and representation is used to assist students in solving the problem. This research is qualitative research that aims to analyze students' representational abilities in solving problems of two-dimensional figure. The research instrument consisted of test questions with a two-dimensional figure material and interviews. The research subjects were 2 junior high school students in Surabaya City who had different representational abilities. The results showed that students had moderate representational abilities, because they gave rise to 2 indicators of representational ability, namely indicators of verbal and symbolic representation in different ways of conveying, but the two subjects had not yet produced indicators of visual representation.

Involvement of cities with county rights in financing tasks pertaining to physical culture
Authors: KRASUCKA Maja
Published: November 2021

Units of local governments in Poland are responsible for running actions in the sphere of physical culture. The growing number of people practicing sports, as well as social and rearing aspects related to sports exert an influence on the activity of sports clubs and social organizations which promote physical culture. While only some sports organizations are self-sufficient economically, most of them must rely on public support. In Poland, like in the majority of European countries, one of the main sources of financing are public grants. Cities with county rights (CCRs), being a specific type of commune, undertake tasks of both communes and counties. In the sphere of tasks pertaining to physical culture this can manifest itself by higher budgetary expenses in general, including grants. Local tasks connected with sport are stiffly defined by central regulations only to an insignificant extent. Therefore it is accepted that local governments possess considerable autonomy as regards deciding about allocation of the means assigned for their realization. This concerns also the grant-based expenses. Thus, the aim of the article is to examine whether the scale of expenses borne on physical culture, including local government grants, is dependent on the size of CCRs and on the level of their financial autonomy. In this paper, the author presents differences in expenses from budgets of CCRs on tasks pertaining to physical culture (Section 926 of the budgetary classification), with particular taking account of grants which constitute them. The basic tools of descriptive statistics and study of interdependences were used. A very large spatial difference in the examined variables, both in the regional framework and within the types of communes, was found. The mean interdependence was identified between grant-based expenses and the level of financial autonomy of the cities with county rights.

Der deutliche Anstieg der Flüchtlingszahlen in den letzten Jahren hat zu einer Veränderung der Rahmenbedingungen für Zuwanderung und des damit verbundenen Diskussionsklimas in Sachsen geführt. Diese Entwicklungen machen politische Konzepte für ein friedvolles und chancengerechtes Zusammenleben in einem Kontext zunehmender Pluralität erforderlich. In den letzten Jahren sind Landesintegrationsgesetze in Nordrhein-Westfalen, Berlin, Baden-Württemberg und zuletzt in Bayern in Kraft getreten. Integrationsgesetze können übergeordnete Ziele der Integration festschreiben und damit zur gesellschaftlichen Selbstverständigung über die Bedeutung, die Reichweite und die Voraussetzungen von Integration beitragen. Die Vorteile eines Integrationsgesetzes liegen dabei vor allem auf der symbolischen Ebene und hängen im Wesentlichen von dem Signal ab, das ein solches Gesetz an alle Bevölkerungsgruppen senden kann. Das vorliegende Gutachten hat das Ziel, den Bedarf, die Voraussetzungen und die Umsetzungsmöglichkeiten für ein Integrationsgesetz im sächsischen Kontext zu prüfen. Einbezogen werden juristische, politikwissenschaftliche und erziehungswissenschaftliche Perspektiven.

Тромботическая микроангиопатия (ТМА) – клинико-морфологический синдром, в основе которого лежит повреждение эндотелия сосудов микроциркуляторного русла, вызванное разными причинами, но проявляющееся сходной клинической симптоматикой и гистологическими признаками. Одним из важнейших триггеров возникновения ТМА является беременность. Во время беременности возможно развитие вторичной ТМА – при тяжелой преэклампсии и HELLP-синдроме или после тяжелой кровопотери, осложнившейся синдромом диссеминированного внутрисосудистого свертывания крови (ДВС-синдромом). Первый клинический пример иллюстрирует роль в индукции атипичного гемолитико-уремического синдрома (аГУС) многочисленных акушерских осложнений и ДВС-синдрома, возникшего в результате своевременно некомпенсированной кровопотери. Их можно рассматривать как дополнительные комплемент-активирующие состояния. Представленное наблюдение иллюстрирует классическое течение вторичного аГУС с характерными признаками ТМА. Прекращение трансфузий свежезамороженной плазмы (СЗП) и начало таргетной комплемент-блокирующей терапии (экулизумаб) привело к значительному улучшению состояния и обратному развитию ТМА. Во втором наблюдении клинико-лабораторные признаки указывали на наличие вторичной ТМА, вызванной преэклампсией, HELLP-синдромом при отсутствии острого повреждения почек. Назначенная базовая терапия преэклампсии, а также введение СЗП и антикоагулянта позволили прервать внутрисосудистый гемолиз.

Thrombotic microangiopathy (TMA) is a clinical morphological syndrome developing as a result of microvascular endothelium damage caused by various reasons but manifesting similar clinical symptoms and histological signs. Pregnancy is one of the most critical TMA triggers. Pregnancy may be accompanied with secondary TMA development in case of severe preeclampsia and HELLP-syndrome or after massive blood loss complicated with disseminated intravascular coagulation (DIC). The first clinical case demonstrates the role of multiple obstetric complications and DIC emerged as a result of failure to timely compensate blood loss in atypical haemolytic-uremic syndrome (aHUS) induction. They may be viewed as additional complement-activating conditions. The described observation illustrates classic progress of secondary aHUS with typical TMA signs. Stopping of fresh frozen plasma (FFP) transfusions and beginning of a target complement blocking therapy (eculizumab) led to significant improvement of condition and TMA involution. In the second observation clinical laboratory signs indicated secondary TMA caused by preeclampsia and HELLP-syndrome without acute renal injury. Prescribed basic therapy of preeclampsia, as well as administration of FFP and anticoagulant, allowed to interrupt intravascular hemolysis.

Anachronisms in Charles Dickens’s ‘Great Expectations’: A Case Study Based on Gerard Genette’s Structural Narratology: الإيقاع الزمني في رواية تشارلز ديكنز "آمال عظيمة" دراسة حالة في ضوء تقنيات السرد البنائي عند جيرارد جينيت
Authors: Rajaa Radwan Hilles Rajaa Radwan Hilles
Published: November 2021

This paper deals with the narrative order of time in Charles Dickens’s novel Great Expectations. Time is crucial in narratological structure as it establishes a logical relation for events in the narrative. Besides, a narrative develops its point of view through the voices in the narrative. This point of view is called focalization. This paper assumes that the sequence of events in Dickens’s Great Expectations does not follow a linear order and consequently, the point of focalization changes throughout the narrative. Accordingly, the current paper intends to investigate the order of narration in the novel. It intends to explore the ultimate thematic concern of the novel as well. The discussion will be in the light of Gerard Genette’s narratological structure and will be applied on Dickens’s Great Expectations. It is the 13th novel in his independent literary works. It has been published unillustrated in 36 weekly instalments in All the Year Round from 1860 through 1861. Then, it has been published in three volumes by Chapman & Hall in1861. The narrative voice has a great impact on the story’s timeline and on the readers because it is narrated in the first-person voice by the protagonist, Philip Pirrip. (Davis, 2007: P 126) The analysis is based on Genette’s theorization of time order in telling a story and communicating a broader point of view that the author intends to make throughout the whole narrative structure.

This study aimed at identifying the legal nature of the activities of the employees of the Public Security Agency, as it is one of the official state departments in spreading security and maintaining public order, and reviewing the role of the public security personnel in administrative control, judicial seizure, preliminary investigation, dealing with juvenile cases, and investigation of new crimes such as human trafficking and electronic crimes.To achieve the objectives of the study, the descriptive analytical approach was used in addition to the legal method, as they are among the most appropriate scientific research methods for the purposes of this study. The study revealed a number of results, including that the Public Security Agency is an armed statutory body that the state bears the responsibility for establishing, organizing, spending on it and providing it with what is necessary to carry out its duties of maintaining security and order. To achieve this, the Public Security Agency follows a comprehensive security strategy whose dimensions are the preventive dimension, the social dimension, the human dimension, the ethical dimension, and the civilization dimension to achieve a set of goals. The study also revealed that one of the most important duties entrusted to the Jordanian public security personnel is consistent with the axes of the public security strategy, including the duties of the main force, administrative control, judicial control, and the original powers of public security personnel for the initial investigation, dealing with juvenile delinquent cases, and the initial investigation of crimes. New developments, such as human trafficking crimes, combating electronic crimes, and protecting intellectual property. In light of the results, a set of recommendations were set, including an emphasis on spreading legal awareness among public security personnel with regard to disciplinary responsibility, criminal responsibility, civil liability, the responsibility of the administrative apparatus entrusted to them during the performance of their duty, and the need to spread awareness among citizens and policemen as far as possible. Whether the role of the Public Security Agency is not limited to security performance, but also to provide service to citizens and society, and then the public interest requires concerted efforts from both parties together to achieve this interest.

A fervent interest in improving patient care, quality of life, and outcomes in adolescent patients undergoing limb Lengthening/ Reconstruction Surgeries (LLRS) has guided the exploration of how psychosocial markers in adolescence may be viewed as crucial to achieving enhanced healthcare delivery. This systematic literature review stems from a retrospective pilot study which investigated the importance of psychosocial aspects in the care of children, adolescents, and young adults who have undergone multiple LLRS. It was determined that such patients value psychosocial support given by their surgeons and caregivers, further promoting psychosocial maturation [1]. Currently, prospective investigation is in the process of being explored as yet another outgrowth of this seminal pilot study. Specifically, the current review seeks to explore the literature relevant to aspects of psychosocial development fundamental to enhancing outcomes of a chronic, orthopedic medical condition. The dearth of studies applying a biosocial lens to this subspecialized field of orthopedic surgery and care supports the need for such expanded investigation.

Additive Manufacturing techniques allow the production of complex geometries unattainable through other traditional technologies. This advantage lends itself well to rapidly iterate and improve upon the design of microwave photonic devices, which are structures with intricate, repeating features. The issue tackled by this work involves compounding a high-dielectric constant material that can be used to produce 3D topological structures using polymer extrusion-based AM techniques. This material was ABS based, and used barium titanate ceramic as the high-dielectric compound of the composite, and involved the use of a surfactant and a plasticizer to facilitate processing. Initial small amounts of material were compounded using an internal batch mixer, and studied using polymer thermal analysis techniques, such as thermogravimetric analysis, rheometry, and differential scanning calorimetry to determine the proper processing conditions. The production of the material was then scaled-up through the use of a twin-screw extruder system, producing homogeneous pellets. Finally, the thermoplastic composite was used with a screw-based, material extrusion additive manufacturing technique to produce a slab for measuring the dielectric constant of the material, as well as a preliminary 3D photonic crystal. The real part of dielectric constant of the composite was measured to be 12.85 in the range of 10GHz to 12GHz, representing the highest dielectric constant ever demonstrated for a thermoplastic AM composite at microwave frequencies. The dielectric loss tangent was equal to 0.046, representing a low-loss dielectric.

Published: November 2021

Donor-acceptor (D-A) conjugated polymers are high-performance organic electronic materials that exhibit complex aggregation behavior. Understanding the solution state conformation and aggregation of conjugated polymers is crucial for controlling morphology during thin-film deposition and the subsequent electronic performance. However, a precise multiscale structure of solution state aggregates is lacking. Here, we present an in-depth small angle X-ray scattering (SAXS) analysis of the solution state structure of an isoindigo-bithiophene based D-A polymer (PII-2T) as our primary system. Modeling the system as a combination of hierarchical fibrillar aggregates mixed with dispersed polymers, we extract information about conformation and multiscale aggregation and also clarify the physical origin of features often observed but unaddressed or misinterpreted in small-angle scattering patterns of conjugated polymers. The persistence length of the D-A polymer extracted from SAXS agrees well with a theoretical model based on the dihedral potentials. Additionally, we show that the broad high q structure factor peak seen in scattering profiles can be attributed to lamellar stacking occurring within the fibril aggregates and that the low q aggregate scattering is strongly influenced by the polymer molecular weight. Overall, the SAXS profiles of D-A polymers in general exhibit a sensitive dependence on the co-existence of fibrillar aggregate and dispersed polymer chain populations. We corroborate our findings from SAXS with electron microscopy of freeze-dried samples for direct imaging of fibrillar aggregates. Finally, we demonstrate the generality of our approach by fitting the scattering profiles of a variety of D-A polymers. The results presented here establish a picture of the D-A polymer solution state structure and provide a general method of interpreting and analyzing their scattering profiles.

Published: November 2021

A emergência dos chamados “fat studies” permite tratar as questões relacionadas ao corpo a partir de categorias políticas associadas à formas de vida e reivindicações sobre um modo de presença. Este artigo delineia alguns aspectos das intersecções entre moda plus size e as representações dos corpos em grupos virtuais de troca e páginas de lojas especializadas na rede social Facebook. A partir da análise dos descritivos de 16 “fanpages” ou grupos voltados a essa temática, foi possível delinear três discursos de dissenso a partir (1) da afirmação da beleza do corpo plus size e do direito de se vestir bem; (2) do reconhecimento e da denúncia de um discurso normativo prévio e (3) da crítica não apenas ao padrão vigente, mas ao arbitrário de qualquer padrão. Esses pontos são discutidos a partir de perspectivas que aproximam política e identidade.

Objetivou-se verificar a influência do enriquecimento ambiental sobre o desempenho reprodutivo de ratos Wistar mantidos em biotério. Doze casais de ratos da linhagem Wistar provenientes do Biotério do Centro Universitário de Patos de Minas foram divididos em quatro grupos com três casais cada: grupo controle (GC) e os grupos com enriquecimento ambiental GEA-1: rolinho de papel, GEA-2: chumaço de algodão e GEA-3: rolinho de papel e chumaço de algodão. Avaliou-se os parâmetros reprodutivos das fêmeas e os índices produtivos das ninhadas. Não foi observado efeito (p>0,05) do enriquecimento ambiental sobre a reprodução dos ratos estudados. Porém, houve uma melhora nas variáveis idade ao primeiro parto, intervalo entre partos, peso ao nascer, taxa de prolificidade e uma diminuição na mortalidade pré-desmame nos grupos enriquecidos. Conclui-se que a utilização de enriquecimento ambiental não influenciou estatisticamente os parâmetros reprodutivos, porém, biologicamente, observou-se aumento da performance nestes parâmetros. O algodão demonstrou superioridade quando comparado aos demais grupos devido à maior facilidade de manuseio do material.

This study describes characteristics of a sample of 80 dog and cat NGOs. When it comes to the results, we used Content Analysis, t-test and z-test to find the confidence interval for the average time of the NGOs’ existence, and Fisher's exact test to compare the ratio for NGOs with/without shelter. The NGOs are located in 49 of the 399 municipalities of Paraná (12.28%). Curitiba presented the largest number of NGOs (n=16), representing 20% of the total organizations. The average time of existence of NGOs in Paraná is 8.75 ± 7.14 years. The oldest NGO was created in 1972, and the most recent one in 2016, that is, 46 and 2 years old, respectively. Organizations’ main source of income is through donations, in 58.56% (n=65) of the cases; only 7.21% (n=7) of them reported having received government support. Also, 48.75% (n=39) are regulated NGOs, and 56.25% (n=45) of them do not have shelter for reception and housing of dogs and cats. This study concluded that the actions of NGOs supported by civil society, community and government are fundamental to mitigate the overpopulation of dogs.

O peixe-boi-marinho (Trichechus manatus) é um dos mamíferos aquáticos mais ameaçados de extinção do Brasil. A reabilitação e soltura dos filhotes resgatados no litoral do nordeste tem sido uma das principais medidas de conservação para a espécie. Foi realizado o relato de caso de um filhote de peixe-boi resgatado pelo Instituto Chico Mendes de Conservação da Biodiversidade Centro Nacional de Pesquisa e Conservação de Mamíferos Aquáticos, que após alimentação com mistura láctea hiperlipídica contendo óleo mineral, passou a apresentar alterações de flutuabilidade e edemaciação da região ventral. Foram realizados exames hematológicos, comportamentais e de imagem no animal. A tomografia computadorizada indicou uma pneumonia lipoide exógena. Para a descrição do caso, foram utilizados os prontuários clínicos da instituição. O protocolo terapêutico preconizado foi realizado em conjunto com o acompanhamento clínico e, sempre que necessário readequado conforme a evolução do quadro. Durante o tratamento, foram fornecido antibioticoterapia, antiinflamatório, polivitamínicos, probióticos, além da alimentação láctea. Após o tratamento terapêutico, o quadro apresentou involução dos achados clínicos e o animal voltou as condições normais, voltando a fazer parte do plantel de soltura de peixes-bois da instituição. Após este caso clínico, foi suspensa na instituição a adição de óleo de origem mineral na alimentação dos animais, pois considerou-se que este fator pode ter sido um agravo ao caso. Este relato documenta as alterações clínicas, diagnóstico e tratamento adotado para a doença em peixe-boi-marinho.

Authors: Jian Yuanxiang
Published: November 2021

This paper mainly introduces the research and application of the technical features, technological principles and construction procedures of the pipe track inner mold in the construction of the pipe track through the silver pipe track project. The inner mold system is composed of trolley support; with a combination of large mold instead of cabin mold scaffold system. The cabin mold scaffold system optimizes the cabin mold system construction from “scaffolding ? installation mold ? reinforcement ? mold removal ? scaffolding removal ? horizontal transfer” to “inner mold trolley installation and commissioning ? trolley in place ? support form ? release mold ? mold movement.” Reduce labor intensity, conserve construction consumables, and assure quality and safety by reducing the expansion, deconstruction, and transfer procedure of the mold and supporting structure. The occupation time of internal mold trolley in each structural construction section is reduced, the trolley turnover efficiency is improved, and the economic benefit is improved thanks to the central support of early mold removal in the workshop, which serves as a model for the construction organization and technical treatment of similar projects.

The inner-urban residential location choice is a topic of continuing interest in urban geography. However, not much research has been done on migrants’ rental location choices. Based on data from a questionnaire completed by 276 migrant renters in Guangzhou, this paper analyzes the demographics and social class characteristics of migrants, and the condition and location of housing preferred by this population. The results show that the migrants in Guangzhou mainly rent in the Center Business District (CBD) area (Tianhe District) and Huangpu, Panyu and Haizhu districts. The main reason for this choice of location choices is the houses’ convenience to their workplaces. A second reason is that nearby subways make travel convenient, for consumption and daily life, for children to go to school, and for access to large shopping centers/malls.
