Abstract
Introduction. In 2014, new scoring system - Kidney Donor Profile Index (KDPI) was introduced. KDPI is a numerical measure that combines ten donor factors, including clinical parameters and demographics, to summarize into a single number the quality of deceased donor kidneys. There are some publications regarding usefulness of KDPI in the first kidney transplant recipients, however there are no data focusing on repeated transplantation patients. Aim of the Study. To determine the usefulness of kidney donor profile index as a risk marker of graft failure in repeated transplantation situations. Material and methods. A single-centre retrospective study was conducted. Patients who underwent a repeated transplantation from deceased donors between 2005. and 2013. were included in the study. Data about donor’s risk factors - age, height, weight, race, history of hypertension, history of diabetes, cause of death, serum creatinine, anti-HCV and if donor is after cardiac death - were collected and KDPI was calculated for all participants. Patients were divided into groups according to determined KDPI: Group 1 - KDPI <35%; Group 2 - KDPI 36 - 69%; Group 3 - KDPI >70%. For statistical analysis, IBM Statistical Package for the Social Sciences, version 21.0 was used. Results. A total of 72 patients were enrolled in the study. There were 17 patients (23.6%) in the 1. group, 38 patients (52.8%) in the 2. group and 17 patients (23.6%) in the 3. group. The most common cause of an end stage renal disease was chronic glomerulonephritis- 59.7% (n=43). Patients with higher KDPI developed acute rejection more often. In the group with KDPI <35% it was observed in 35.3%, while in the groups with KDPI 36 - 69% and KDPI >70% in 60.5% and 64.7% of patients, p = 0.02. Graft function differed significantly both, after one (p =0.01) and three years (p=0.04) with the highest eGFR results in the group with the lowest KDPI. The difference in graft survival rates was statistically significant, p = 0.027. After three- years it was 88.2% in the first group, 86.8% in the second group and 70.6% in the third group. Patient survival rates showed trend toward significance (p = 0.076) with only two patients lost during three- year follow up. Conclusions. KDPI presents relevance with repeated transplantation outcomes. Lower KDPI indicates better transplantation outcomes - superior graft function and better graft survival. However, there is only trend towards significance in patient survival rates.
Computation of the Thermal Residual Stresses in SiC/SiC Composites with Multi-Layered Interphases by Using ANN with the Structure of Random Forest

Published: September 2018

AbstractIn this paper, a hybrid strategy incorporating finite element computation, artificial neural network (ANN) method and Random Forest (RF) algorithm is proposed for computation of the thermal residual stresses (TRS) in SiC/SiC composites with multi-layered interphases. The finite element method is adopted to calculate the TRS of the unidirectional SiC/SiC composites. The ANN with the structure of Random Forest (RFANN) is employed to approximate the non-linear relationship between the multi-layered interphases thicknesses and the TRS of the SiC/SiC composites. The well-trained RFANN is finally used to compute the TRS of a unidirectional SiC/SiC composite with six layers of interphases.

Abstract
The electrically conducting three-dimensional Williamson fluid flow produced by the movement of sheet via porous medium under non-uniform heat sink and source, thermal radiation and convective boundary condition is examined. The system of nonlinear expressions is transformed into nonlinear ordinary differential system of equations. These governing expressions are evaluated numerically with the help of boundary value problem default solver in MATLAB bvp4c package. Pertinent results are demonstrated graphically to execute the effects of various governing parameters on dimensionless fields. The aspects of constraints on skin-friction, mass and heat transport rates are characterized via numerical benchmarks. It is noticed that the transverse and axial velocities are depreciated by respective Williamson fluid parameters, while the opposite trend is noticed on concentration and temperature fields.
Integration mechanism and transcendental semiosis
Authors: Lee Ji Hwan 
Published: September 2018

AbstractCognition consists of multiple layers. Each neuron group in layers processes information and transmits it to other layers. The more information is integrated, the more obvious and usable signs become. Horizontally, signs in semiosis are associated and mediated with each other. Vertically, they collaborate beyond the horizon; from sensory neuron to reflective consciousness. Semiosis involves trying to reach final interpretant through following a possible interpretation-course by the force of a guiding principle. Whereas, in trans-semiosis, we attempt to integrate two semioses despite their conceptual gap. In that situation, transcendence occurs. If integration is impossible, semiosis would rev up excessively. Accordingly, intense neural stimulations are generated. Once probable routes of interpretation have rapidly accumulated in quantity, they cross a threshold where restrictions are broken or do not exist. Then, we jump to a stable belief, attaining trans-interpretance that has competence for casually suturing a conceptual gap without any adequate foundation. The overflow of stimulation integrates into transcendence feelings that deviate from cognitive boundaries. That momentary strong feelings and trans-interpretance are connected with each other by a memory mechanism. Trans-interpretance creation leaves some unresolved surplus, reminding us of the once ignored gap and reactivate semiosis. However, if trans-interpretance is reformed and semiosis comes to a lull again, they can be strengthened.
Coherence and truthfulness in communication: Intracommunicational and extracommunicational indexicality
Authors: Elleström Lars 
Published: September 2018

AbstractThe aim of this article is to construct a model that demonstrates how human communication, involving all kinds of media, may not only correspond to but also put us in contact with what we perceive to be the surrounding world. In which ways is truthfulness actually established by communication? To answer this, the notion of indices is employed: signs based on contiguity. However, an investigation of indices’ outward direction – creating truthfulness in communication – also requires an understanding of their inward direction: establishing coherence. To investigate these two functions, further concepts and various elementary categorizations are proposed: it is argued that there are several types of contiguity and many varieties of indexical objects, which invalidates the coarse fiction–nonfiction distinction.

Abstract
The strong association among the risk of coronary artery diseases (CAD), high levels of LDL-C and low levels of HDLC is well established. Hyperhomocysteinaemia (HHcy) is an independent risk factor for cardiovascular disease (CVD) and causes endothelial dysfunction, a hallmark of atherosclerosis. In this study, we ascertained the influence of statins on the atherogenic index, as an indicator and a significant adjunct for predicting atherosclerosis in hyperhomocysteinaemic male Wistar albino rats. For 4 weeks, the animals were fed with one of the following diets (Mucedola SRL., Milan, Italy): standard rodent chow; a diet enriched in methionine with no deficiency in B vitamins or a diet enriched in methio-nine and deficient in B vitamins. The animals were simultaneously exposed to a pharmacology treatment with atorvastatin at dose of 3 mg/kg/day i.p. or simvastatin, at dose of 5 mg/kg/day i.p. We measured weight gain, food intake, and FER and determined the concentrations of biochemical parameters of dyslipidaemia (TC, TGs, LDL-C, VLDL-C, and HDL-C), AI, and CRR. A histopathological examination was conducted on portions of the right and left liver lobes from each animal. A connection between Hhcy and dyslipidaemia was indicated by the findings of biochemical and histological analyses, suggesting that Hhcy was a pro-atherogenic state. An improvement in the lipid profile along with a decrease in the atherogenic index by statins suggests that atorvastatin and simvastatin could be useful antiatherogenic agents, with protective activities during hyperhomocysteinaemia.
A parametric stationarity test with smooth breaks
Authors: Tsong Ching-Chuan , Lee Cheng-Feng , Tsai Li Ju 
Published: September 2018

Abstract
We propose a test to investigate the stationarity null against the unit-root alternative where a Fourier component is employed to approximate nonlinear deterministic trend of unknown form. A parametric adjustment is also adopted to accommodate possible stationary error. The asymptotic distribution of the test under the null is derived, and the asymptotic critical values are tabulated. We also show that it is a consistent test. Even with small sample sizes often encountered in empirical applications, our parametric stationarity test employing Fourier term has good size and power properties when trend breaks are gradual. The validity of the Fisher hypothesis for 15 OECD countries is investigated to illustrate the usefulness of our test.

Analysing Activities in a Classroom - Remembrances of Professor John Aitchison in Hong Kong with Applications to a Service Provider
Authors: Coleman Shirley Yvonne 
Published: September 2018

Compositional data analysis formed a main focus of statistical activities at Hong Kong University when Professor John Aitchison was head of the Statistics department. It was part of a new Master's degree in Statistics that he set up, and as this was the first such post graduate degree to be offered in Hong Kong, it attracted many gifted statisticians from the Government Statistical Service and other employments making it a very lively program.
Acknowledging the constrained nature of many types of data led to a new way of looking at proportions and percentages of components making up data items. Professor Aitchison's seminal book The statistical analysis of compositional data contains background theory and many examples of data arising from a wide variety of applications such as geology, economics and human behaviour. One example was an analysis of the daily activities of a statistician. This prompted an analysis of classroom activities in a range of classes and schools encountered during teacher training within the Professional Educational Studies department of Hong Kong University. It was found that the nature of the target class and the school level affected the pattern of lesson activities with more listening carried out in the higher target classes and higher level schools. More time was spent dealing with educational equipment in lower level schools.
Data analytics is increasingly popular in all walks of life and many small and medium enterprises are realising the benefits. Compositional data forms a large part of internal company operational data and its analysis can provide useful insights. For example, the change in proportions of different activities undertaken over time is important information for a service provider. In addition to biplots and coordinate representations of isometric log ratios, using ternary diagrams to illustrate proportions is an informative way to share findings with company staff.

Esse estudo teve por objetivo dimensionar a entrada ambulatorial de pacientes na Divisão de Clínica Obstétrica - DCO do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, em função do número de leitos disponíveis. Utilizou-se a metodologia de estudo de caso quantitativo com acesso ao banco de dados do serviço, referentes aos meses de julho de 2015 a abril de 2016. Utilizou-se a Equação de Erlang-B para calcular, a partir da taxa de ocupação, da média de permanência das pacientes, do número de leitos disponíveis, da taxa de recusa desejada e do histórico de entradas das gestantes, qual seria o redimensionamento necessário no ambulatório da DCO. Nos 10 meses de análise, a taxa de ocupação média foi de 84,2%, a média de permanência foi de 2,8 dias. Para 13 leitos disponíveis, taxa de recusa de até 5% seria atingida com uma demanda calculada de 3,2 chegadas/dia no serviço. Conclui-se que para se atingir taxa de recusa de até 5% na DCO seria necessária uma redução de 9 a 35% na entrada mensal ambulatorial, de acordo com o percentual de redução de entradas de pacientes “externas”, via pronto-socorro, para parto no serviço.Palavras-chave: Dimensionamento.

Centro Educacional Teodoro Sampaio: os Saberes Matemáticos na Formação dos Professores das Séries Iniciais em Santo Amaro (1954-1971)

Published: September 2018

Neste artigo, analisamos os saberes matemáticos na formação dos professores primário no Centro Educacional Teodoro Sampaio no período de 1954 – ano de sua inauguração como centro formador de professor primário – a 1971 – o ano em que foi sancionada a Lei 5.692, a qual reformou a Lei de Diretrizes e Bases da Educação Nacional de 1961 ao estabelecer uma nova classificação serial para a educação básica e ampliar a sua obrigatoriedade. Neste sentido, além de termos nos apoiado nas categorizações de saberes a ensinar e saberes para ensinar, apropriadas, recentemente, por Valente (2016), fizemos uso de documentos históricos pertencentes a esse centro de ensino e de uma historiografia da educação e da própria história. A partir dessa análise, argumentamos que pelo menos ao longo da década de 1960, nesse centro santamarense, os saberes a ensinar, dados nas disciplinas escolares continuavam tendo domínio na formação dos professores primários. Essa realidade permanecia mesmo após os saberes para ensinar, ainda que oscilando de um ano para outro, terem ganhado paulatinamente mais espaço na formação dos professores que ensinariam nas séries iniciais.Palavras-chave: Saberes Matemáticos.

In this sense, in addition to having been supported in the categories of knowledge to be taught and knowledge to teach, recently adapted by Valente (2016), we have used historical documents belonging to this teaching centre and a historiography of education and history itself. From this analysis, we argue that, at least during the 1960s, in the santamarense centre, the knowledge to be taught provided in the school subjects continued to dominate the formation of primary teachers. This reality remained even after the knowledge to teach, even though they oscillated from one year to another, they gradually gained more space in the formation of the teachers who would teach in the initial grades.Keywords: mathematical knowledge.
