Published: April 2020

This study aimed to describe the statistical methods used and statistical practice in PhD thesis in sports and exercise sciences, and to examine the time trends of statistical methods prevalence. We analyzed 50 PhD theses supported by a post-graduate program recognized by CAPES and defended between January 2003 and December 2013. Most theses used more than two statistical methods, and T-test, ANOVA, multiple comparisons, correlation and reliability analysis were the most used approaches. Less than 50% of both experimental and observational theses reported the effect size (ES), confidence interval (CI), sample size calculation and observed power analysis. The use of multiple comparisons in experimental studies significantly increased in the last 5-years compared to 2004-2008 time period. No other significant changes were observed. Results suggest that several statistical methods are used in quantitative design studies. Due to the observed large prevalence of statistical deficiencies (lack of reporting ES, CI, power analysis), postgraduate programs should have qualified statisticians with a major say in checking the statistical quality of PhD theses and subsequent articles.

Published: April 2020

A presente investigação tomou como base os pressupostos teóricos do advocacy coalition framework para analisar a política de gestão do esporte Orientação, considerando o processo de ruptura apresentado pela Confederação Brasileira de Orientação nos últimos dois anos, depois de passar mais de 16 anos sem evidenciar mudanças significativas. O objetivo geral dessa pesquisa é analisar, a partir da estrutura teórica do advocacy coalition framework, as principais modificações ocorridas na gestão da Confederação Brasileira de Orientação decorrentes do seu processo de ruptura política. Além disso, objetiva especificamente identificar as coalizões de defesa que compõem o subsistema do esporte Orientação brasileiro; descrever os sistemas de crenças de cada coalizão; e ponderar sobre a aplicação desse modelo na análise de entidades de organização esportiva como a confederação estudada. Possui natureza teórica, abordagem qualitativa e objetivo descritivo e analítico. Apresenta o resultado de pesquisas bibliográfica e documental, com recorte temporal compreendido entre 1999 e 2018 e interpretação de dados por meio de análise de conteúdo. Foram evidenciadas duas coalizões, a primeira delas foi chamada Coalizão das Múltiplas Vertentes, de acordo com suas crenças de núcleo profundo, centraliza a gestão da Orientação em torno de sua confederação nacional e compreende esse esporte enquanto um fenômeno abrangente, englobando ao mesmo tempo esporte, lazer e produto turístico. A segunda, Coalizão da Vertente Competição, compreende a Orientação apenas como um fenômeno esportivo competitivo e entende sua gestão de forma descentralizada. Dessa forma, o advocacy coalition framework contribuiu para compreender o processo de ruptura dentro da política da Orientação no Brasil, que culminou nas mudanças na forma de gerir o esporte percebidas nos últimos anos.

Os pequenos jogos são um meio de treinamento que possui diversas formas de manipulação. As manipulações, por sua vez, permitem aos treinadores modelar o jogo de acordo com o objetivo proposto para a atividade. No entanto, essas manipulações podem influenciar na interação entre os jogadores durante o processo ofensivo da equipe. Esta pesquisa analisou a influência do critério de composição das equipes na rede de interações nos pequenos jogos. Participaram do estudo doze atletas de futebol sub-15 de uma equipe de alto nível da cidade de Curitiba. Atletas realizaram 4 séries de pequenos jogos na configuração 3vs.3 + goleiros em duas composições das equipes: a) com atletas de uma mesma posição (e.g., três atacantes); e b) com atletas das três posições (e.g. um defensor, um meio-campista e um atacante). Analisaram-se padrões de network (referentes a equipe – análise macro) e níveis de proeminência (referentes aos atletas – análise micro) no âmbito da Social Network Analysis. Para a análise micro utilizou-se a ANOVA one-way (e o teste de Kruskal-Wallis para variáveis não paramétricas) para comparação dos valores entre diferentes posições. Para a análise macro, utilizou-se o teste t independente (e o teste de Mann-Whitney para variáveis não paramétricas) para comparação entre os protocolos. Em todos os casos adotou-se significância de p

Cervix cancer is one of the most common cancers in women, particularly in developing countries and Asian countries that many science centers around the world consider the pap smear screening test as the best solution for the control of cervical cancer. Several studies have shown that to tend women for doing a pap smear is regularly decreasing, and about one-fifth of women have not had a pap smear. This study was done to investigate rate and causes of the cervix cancer screening test among women Ardabil. In this cross-sectional study, 300 women referred to health centers in Ardabil were selected by multistage sampling. Data were collected through a researcher made questionnaire. For data analysis, SPSS Software version 18 and descriptive and inferential statistics were used. The rate of cervical cancer screening test in this study was 48%. The role of knowledge as personal factors of pap smear screening test was significant statistically (p<0.05). Among the risk factors for cervical cancer, there was observed significant relationship between uterine diseases history and number of pregnancies and pap smear test (p<0.05). Of family and social factors on women's education and employment, occupation and level of education was no significant relationship with using pap smear test. However, there was a significant relationship family history of cancer and pap smear test (p<0.05). In all, prevention is always prior to treatment. One of the prevention ways is the screening test. Early diagnosis and early treatment of cervical cancer has a key role. So the female population needs planning by intervention programs for health education and regular screening to prevent cancer.

Cancer is the second common cause of death worldwide and a significant ratio of all cancers is related to occupational and living environments. On the other side, cancer prevalence could be controlled and prevented via policies to improve occupational and living environments. However, a main challenge in prevention of occupational cancer is the lack of knowledge about the exposure rate and number of exposed persons. CAREX database, which is established by the program of Europe against cancer, provides information for the number of exposed persons based on country, carcinogen, and type of industry. CAREX is established in early years of 1990 decade by Finland Institute of Health (FIOH) in cooperation with IARC and European experts, as a tool for estimation of the burden due to occupational cancer in Europe, and shortly thereafter is expanded for use in almost 15 countries in European Union by 55 industrial groups. Several other countries have used CAREX for their countries and have provided some main progressions for the performance model. CAREX project in Canada was modeled in 2007, in an effort to develop a Canadian specific and advanced tool for assessing exposure to carcinogenic agents based on EU CAREX. In this model, not only occupational exposure, but also environmental exposure has been considered. Estimation of exposure with CAREX helps to inform primary prevention activities and to improve global occupational cancer, and its strength points are systematic nature, good coverage and ease of use, and can be used in other countries of the world.

Conventional diagnostic test have limitations to deferential diagnosis in clinical suspicion ofbacterial infection cases, that in some cases lead to inappropriate antibiotic therapy and increases antibiotic resistance. A new diagnostic insight is procalcitonin (PCT) test to improve diagnosis of bacterial infections and to guide antibiotic therapy. Serum PCT levels are of useful test as a biomarker in patients with bacterial infections for several reasons. Initial rise of PCT levels due to bacterial infection, subsequent sequential PCT levels can be used to assess the effectiveness and duration of antibiotic therapy. Based on clinical researches results, in bacterial infections, promising good results obtained when use of PCT used as differential diagnostic test. But further intervention studies are needed before use of PCT in clinical routine tests. The goal of this review is to study the PCT reliability as infections diagnostic biomarker.

Published: April 2020

Introduction: Hearing loss is one of the most common causes of disability of more than 1.33 billion people worldwide and, according to WHO research, failure to timely detect hearing loss has detrimental effects on the individual, the family and the world economy ($ 750 billion), Therefore, exposure to excessive noise and exposure to organic solvents can cause hearing loss in individuals.

Methods: This descriptive-analytical study was performed on a manufacturing company with a statistical population of 17 people (8 employees of printing and electroplating unit with a mean age of 40±4.78 and 9 employees of Coldwell unit with a mean age of 4.33±41). Data were analyzed by SPSS software version 16 and paired T-test.

Results: According to the pollutant results in the Coldwell unit, the noise level was exceeded, but the toluene levels were measured at the permissible level, which, according to the software output, showed a faster rate of hearing loss (Right ear sig = 0.007 and left ear sig = 0.002)

and also, in the printing and plating unit, the sound level was above the permissible limit, but the toluene level was exceeded, which according to the software output of these units had a lower rate of hearing loss.

Conclusion: The results of this study show that simultaneous exposure to noise and organic solvents such as toluene in the workplace accelerates the Occupational Hearing Loss Process, as well as employees who are not exposed to noise, are reasonably hearing impaired due to exposure to toluene.

Published: April 2020

Dismenorea merupakan nyeri yang dirasakan ketika haid, untuk menangani nyeri haid tersebut ada dua hal yang dapat dilakukan yaitu secara medis dan non-medis. Nyeri saat haid tidak boleh dibiarkan begitu saja tanpa adanya upaya penanganan, karena mungkin saja gejala endometriosis bisa mempersulit wanita untuk hamil. Wanita Indonesia yang mengalami dysmenorhe lebih banyak mengatasinya dengan mengkonsumsi obat-obatan penghilang rasa nyeri yang beredar dipasaran. Sebagian masyarakat mempunyai anggapan yang salah bahwa nyeri ini dapat hilang dengan sendirinya apabila wanita yang bersangkutan menikah, sehingga mereka membiarkan gangguan tersebut. Penelitian ini bertujuan untuk mengetahui hubungan antara usia dan pengetahuan dengan penanganan dismenore. Metode penelitian ini  dengan menggunakan metode korelasi menggunakan sampel secara acak sistematis terhadap 60 siswi. Hasil penelitian Tidak terdapat hubungan antara usia responden dengan cara penanganan dismenore dengan nilai p 0.429 lebih tinggi dibandingkan nilai α 0.05. Terdapat hubungan yang signifikan antara tingkat pengetahuan dengan cara penanganan dismenore dengan nilai p 0.012.

Berdasarkan hasil penelitian tersebut diharapkan Remaja putri  diharapkan dapat memilih cara penangan untuk menurunkan nyeri saat menstruasi (dismenore) dengan cara yang aman sehingga tidak memberikan efek yang membahayakan bagi tubuh. Agar peneliti selanjutnya dapat meneliti variabel-variabel lainnya yang belum diteliti dalam penelitian ini.

'Much exertion of the voice and great application of the mind': Teacher Education within the Congregation of the Sisters of St. Joseph of Toronto, Canada, 1851-1920
Authors: Smyth Elizabeth
Published: April 2020

In the introduction to their recent collection of essays on the experience of women teachers in North America, Britain, and Australia, Prentice and Theobald comment on the complexities involved in documenting and analyzing the histori cal experience of women who taught in both private and public schools. The research reported in their collection substantiates the opening statement: the history of women who taught is indeed a complex one. The editors' candid observations about what is known and what remains unknown about the working lives of women who taught and their call for ongoing research likewise validate the opening quotation. This article concerns a doubly marginalized group of teachers: women religious who taught in both the private and public schools of Ontario. It begins to address Prentice and Theobald's challenge that these teachers need to be 'rescued from the hagiographic historical tradition in which they are customarily presented' by providing a case study of the evolution of teacher education within one community of teaching sisters in English Canada: the Congregation of the Sisters of St. Joseph in the Archdiocese of Toronto. Utilizing a framework of documentary analysis, the article sets both a theoretical and historical context against which to examine communities of teaching sisters. It concludes by suggesting further avenues for research which, in themselves, indicate the com plexity of analyzing the historical experience of women who taught in the nineteenth and twentieth centuries.
Missionary Women as Educators: The CMS School in New Zealand, 1823-1835
Authors: Fitzgerald Tanya
Published: April 2020

Much of the literature on the early period of British colonization of New Zealand has assumed that missionary men participated in the public world of work while their wives participated in the private world of the home. As women have been seen as occupying the domestic sphere of the home, historians have further viewed their work as relatively unimportant. Across this literature it is also usually assumed that—probably because men were engaged in the 'public sphere'—it was the missionary men who were responsible for providing education. This paper concentrates on the activities of two early missionary women, Marianne Williams and her sister-in-law, Jane Williams. There is concrete evidence to suggest that these women were sent to New Zealand as part of the first wave of missionary women to 'civilize' Maori by converting them to Christianity. As women and educators, Marianne and Jane played critical roles in the success of the mission and, as will be argued, their presence in the mission station permitted missionary men to undertake their duties.
Ontario School Teachers: A Gendered View of the 1930s
Authors: Reynolds Cecilia , Smaller Harry
Published: April 2020

This particular article arises out of a longitudinal empirical study on teacher socialization with specific regard to relations of gender, ethnicity, and race. It focuses on a number of observations about Ontario teachers in the 1930s:1. The overall percentage of men in teaching rose, but much more so in rural areas than in the cities. 2. Salaries of teachers dropped considerably during this time. 3. There was a significant change in teacher certification procedures, within which gender played a large role. Salaries were also affected by these certification changes.4. Average ages of teachers increased significantly during this decade. 5. In general, teachers had more years of teaching experience than their colleagues did in the previous decade. However, there were significant gender differences in these figures. 6. Both formal and informal policies against the employment of married women as teachers were enforced. This article details these observations, and then discusses what significance they may have had, in the context of overall 'gender relations' among teachers in Ontario. A number of relevant sources for the 1930s were examined: annual reports of the Ontario Department of Education; annual reports, minutes, and handbooks of the Toronto Board of Education; and contemporary newspapers. In addition, reprinted transcripts of two groups of interviews have been drawn on—six men and women who taught (and later became principals) in Toronto in the 1930s, and a number of women teachers from the 1930s who were inter viewed for a 1980s study on women's experiences during the Depression.

Authors: Loizidis Theodoros , Nikodelis Thomas , Bakas El. , Kollias I.
Published: April 2020

BACKGROUND: Pain relief is important both for the movement of patients suffering from low back pain and the quality of life. Dry needling is effective on myofascial trigger points but its effect on the area of pain and the functional balance is not fully known. OBJECTIVE: To examine the immediate effect of dry needling on pain and functional balance of patients suffering from low back pain. METHODS: Twenty five patients with sub-chronic low back pain were randomly divided into two groups: the intervention or control group. Needles were used for the participants of the intervention group, bilaterally at the spinus level, one and a half finger breath from the midline in levels L2–L5 of the lumbar spine. A third line of needles was inserted in the interspinosus spaces, except L5-S1 level. Bipedal stance, lateral loading and mediolateral body sway were assessed using a pair of force plates. Pain tolerance was assessed using an algometer. RESULTS: The pain tolerance significantly increased in the intervention group from (M = 4.87, SE 0.663) to (M = 6.52, SE 0.547) (F(1,23) = 7.8, p< 0.05) after intervention. During mediolateral body sway the force signal in the dominant frequency significantly increased in the intervention group from (M = 43.2, SE 4.6) to (M = 54,9, SE 3.6) (F(1,23) = 4.63, p< 0.05) after intervention, exhibiting more controlled rhythmic behavior. CONCLUSIONS: Dry needling in painful areas and penetrating all the muscle groups seems to improve pain and functional balance, yet its effect on specific muscles needs to be studied further.
Robust stability condition of an adaptive control for a class of uncertain discrete-time SISO system
Authors: Jiang Xuecheng , He Dongwei
Published: April 2020

For a class of uncertain discrete-time linear single-input and single-output (SISO) system with control inputs without disturbances, an adaptive control strategy is proposed, which includes a compensation controller based on normalized least mean square (LMS) parameter identification algorithm and a state feedback controller. Then the state feedback controller is designed on base of the discrete-time algebraic Riccati equation (DARE) of nominal parameter system. But the performance of the control system will deteriorate by relying solely on this state feedback controller when the system parameters change. So designing a feed-forward compensation controller based on the parameter error makes the original design still valid after the parameters change. And sufficient stability condition and error bound of uncertain parameters that satisfy the DARE of uncertain linear systems is also derived in detail.
Weld pool image procession based on the Fourier-DNA low-pass filtering
Authors: Ding Dukun
Published: April 2020

In order to extract the character of weld pool, a new method for weld pool image procession based on the Fourier-DNA low-pass filtering is proposed. Firstly, the TIG welding technique is chosen to be the researched object. The welding experimental system is setup, which is used to capture weld pool images in real time. On this basis, Fourier transformation is performed to weld pool image, and changed the space domain to frequency domain. Then the DNA low-pass filtering is constructed. The DNA intelligent algorithm is used to obtain the optimum low-pass cut-off frequency, and the low-pass filtering can be obtained. The binaryzation operation by the optimum low-pass filtering method and the traditional otsu method have been done. The results show that the method proposed in the paper has a better binaryzation performance. In the end, canny edge extract operation are performed. So the weld pool image edge can be obtained, which has made some basis for the extraction of weld pool character latter on.
On variable-precision-based rough set approach to incomplete interval-valued fuzzy information systems and its applications
Authors: Li Juan , Shao Yabin , Qi Xiaoding
Published: April 2020

With respect to multiple attribute group decision making problems in which the attribute weights and the expert weights take the form of real numbers and the attribute values take the form of interval-valued uncertain linguistic variable. In this paper, we introduce the idea of variable precision into the incomplete interval-valued fuzzy information system and propose the theory of variable precision rough sets over incomplete interval-valued fuzzy information systems. Then, we give the properties of rough approximation operators and study the knowledge discovery and attribute reduction in the incomplete interval-valued fuzzy information system under the condition that a certain degree of misclassification rate is allowed to exist. Furthermore, a decision rule and decision model are given. Finally, an illustrative example is given and compared with the existing methods, the practicability and effectiveness of this method are further verified.
VAR assessment under nongaussian distribution of returns
Authors: Barysheva A. Е. , Markov A. S. , Mitcel A. A.
Published: April 2020

The study aims to assess the impact of violation of the assumption about normality of the investment portfolio returns on its risk measures. The article is focused on the Value at Risk (VaR) metric required by major regulatory authorities for bank risk assessment. Using historical share prices of several Russian companies it is shown that the assumption about returns normality is not supported by statistical tests. It is also shown that the empirical distribution of the assets returns is described by Johnson’s distribution. The Kolmogorov-Smirnov test supports the obtained results. The tests proposed by the authors allow estimating the loss in accuracy in parameters calibration of the autoregressive model, obtained by using the maximum likelihood method when the asset returns have non-gaussian distribution. It was found that the loss in the accuracy lies in the range [22%, 26%] for absolute returns and in the range [33%, 38%] for relative returns depending on the autoregression parameter which varies in the range [–0.9, 0.9]. The error of ten-day VaR estimation was calculated for 1% (99%) and 5% (95%) significance levels. At a significance level of 5% (95%) the VaR metric obtained under the assumption that the asset returns have normal distribution is lower than the true value by 7% (6%) for absolute returns and 4% (13%) for relative returns, which indicates strong underestimation of the portfolio risk. At a significance level of 1% the metric is conservative exceeding the true value by 12.5%.
Analysis of the high order ADL(p, q) models used to describe connections between time series
Authors: Kalugin T. R. , Kim A. K. , Petrusevich D. A.
Published: April 2020

In the paper the mathematical models describing connection between two time series are researched. At first each of them is investigated separately, and the ARIMA(p, d, q) model is constructed. These models are based on the time series characteristics obtained during the analysis stage. The connection between two time series is confirmed with the aid of cointegration statistical tests. Then the mathematical model of the connection between series is constructed. The ADL(p, q) model describes this dependence. It’s shown that for the time series under investigation the ordersp, qof the ADL(p, q) model are connected with the ARIMA(p, d, q) orders of the  describing each series separately. This step makes the set of the investigated ADL(p, q) models much smaller. In the previous papers it was also shown that the ARIMA(p, d, q) automatical fitting functions in popular packages use limitations on thep,qorders of the time series process:q≤ 5,p≤ 5. The wish to use the simplest models is also built in the structure of the Akaike (AIC) and Bayes (BIC) informational criteria. In the paper the maximal values of the ADL(p, q) model orders are supposed to be the orders of the appropriate ARIMA(p, d, q) series. In the previous work it was shown that using high order ARIMA(p, d, q) it is possible to fit the models better. In this paper the experiments on the ADL(p, q) models construction are presented. The wage index and money income index time series pair is researched, and also the gas, water and energy production and consumption index/real agricultural production index pair is investigated. The data in the 2000–2018 time period is taken from the dynamic series of macroeconomic statistics of the Russian Federation.
МОДЕЛЬ СТРЕСОСТІЙКОСТІ СОЦІАЛЬНИХ ПРАЦІВНИКІВ РІЗНИХ ВІКОВИХ ГРУП
Authors: Тептюк Юлія
Published: April 2020

У статті обґрунтовується модель стресостійкості соціального працівника. Зазначається, що від успішного вирішення питань розвитку стресостійкості залежить ефективність професійної діяльності соціальних працівників, здатних підтримувати високу опірність негативним діям, доцільність поведінки, зберігаючи психофізичне благополуччя, здійснюючи пошук шляхів забезпечення успішного функціонування та підвищення безпеки своєї праці. Під час теоретичного аналізу професійної діяльності соціальних працівників різних вікових груп виокремлено дві основні групи джерел стресу в їхній професійній діяльності – зовнішні і внутрішні. З метою оцінки правомірності виокремлення виокремлених стрес-чинників здійснено аналіз результатів опитування респондентів про джерела стресу в їхній професійній діяльності. На основі узагальнення уявлень про ресурси стресостійкості особистості соціального працівника розроблено та обґрунтовано модель його стресостійкості, яка складається із трьох блоків: індивідуально-психологічні характеристики особистості соціального працівника, соціально-психологічні характеристики його особистості та характеристики поведінки соціального працівника у стані стресу. Зазначені блоки складають структуру стресостійкості соціального працівника, яка є загальною і для працівника з розвиненою стресостійкістю, і для працівника із нерозвиненою стресостійкістю. Їхня відмінність полягає в якісних і кількісних особливостях змістовних елементів, із яких складаються ці блоки.

İnfertilite olgularının yaklaşık %15’inde infertilite sebebi olabilecek bir patoloji saptanmayıp, açıklanamayan sebeplerle konvansiyonel gebelik gerçekleşmemektedir. Araştırmalar, sperm DNA hasarının üremeye yardımcı tekniklerin (ÜYT) sonucunu olumsuz etkilediğini ortaya koymuştur. Çekirdek bütünlüğü korunmuş olan spermleri seçmeye yönelik non-invaziv yöntemler geliştirilmekle birlikte, bu yöntemlerin açıklanamayan infertilite olgularında ÜYT başarısı üzerindeki etkisi henüz tartışmalıdır. Bu çalışmada DNA hasarlı spermlerin dansite gradient santrifüjü (DG) yöntemi ile tek başına ve non-invaziv manyetik aktivasyonla hücre ayırma (MACS) yöntemiyle birlikte eliminasyonu sonrası kullanılan spermlerin fertilizasyon ve erken embriyoner gelişime etkisi karşılaştırılarak uygun semen hazırlama yönteminin saptanması hedeflenmiştir. Açıklanamayan infertilite tanısıyla ÜYT programına alınan çiftlerde, DG yönteminin tek başına ve MACS yöntemiyle birlikte kullanımının, kaliteli sperm elde etmedeki başarısı, her iki yıkama metoduyla elde edilmiş spermlerde TUNEL yöntemi ile DNA bütünlüğü açısından ve Hematoksilen Eosin boyamasıyla morfolojik açıdan değerlendirildi. Klinik parametrelere etkisini değerlendirmek amacıyla, her iki yıkama yöntemiyle elde edilen spermlerin ICSI sonrası fertilizasyon ve embriyo gelişimsel potansiyeline bakıldı. MACS+DG yöntemiyle yıkanan sperm örneklerinde sperm DNA fragmantasyon oranının ve vakuol (+) sperm oranının DG yöntemiyle elde edilen spermlere kıyasla istatistiksel olarak anlamlı düzeyde azaldığı görüldü. DG veya MACS+DG ile yıkanan spermlerle mikroenjeksiyonu gerçekleştirilen oositler arasında fertilizasyon ve embriyo gelişimsel potansiyelinde bir farklılık oluşmaması intrasitoplazmik sperm enjeksiyonu uygulamalarında spermin doğal seçiliminin söz konusu olmamasının bir sonucu olduğu düşünülerek, MACS tekniğinin ICSI protokollerinde gerekli olmadığı, spermin doğal seçiliminin gerçekleştiği intrauterin inseminasyon (IUI) ve IVF uygulamalarında daha etkin olacağı sonucuna varıldı.
O saber inconsciente do sujeito e o desejo do analista na clínica das toxicomanias
Authors: Rocha Lorena Fabiani da
Published: April 2020

O atendimento clínico a pacientes toxicômanos exige que se observem dimensões inconscientes do sujeito que se droga e do analista que o acompanha, considerando que tais dimensões antecedem e implicam a condição de dependência do paciente. Desta forma, este trabalho tem por objetivo esclarecer perspectivas psicanalíticas que norteiam a abordagem do fenômeno toxicômano no setting de atendimento. Tomaram-se conceitos como “inconsciente” e “desejo do analista” a fim de elucidar a forma como a situação analítica constitui um tratamento individualizante e se contrapõe ao método da psiquiatria clássica. Para tanto, ressalta-se a existência de um saber particular em cada paciente acerca de sua drogadição, o qual não foi previsto pela nosologia médica. Considera-se, pois, insuficiente a técnica psiquiátrica e se explora uma abordagem que busca melhor interpretar a toxicomania, tendo como ferramenta basilar o desejo do analista. Além dos conceitos centrais trazidos pelo título, o trabalho também passa pelas noções de “linguagem”, “mal-estar na cultura”, “eu”, “monomania”, “castração” e “maturação pulsional”. A pesquisa partiu do método de investigação bibliográfica, tangendo o tema “Toxicodependência” no âmbito da Psicanálise e da Psiquiatria clássica. Recorreu-se à literatura de autores consagrados que entrecruzam tais saberes, como Freud, Lacan e Bercherie.

Palavras-chave: Toxicomania, análise, atendimento clínico, psiquiatria clássica.

Authors: Drozda﻿﻿ Łukasz
Published: April 2020

The dissemination of social media and the growing resources of big data create both new opportunities for urban space analysis and new challenges for contemporary policy making. Among the sources useful from this standpoint there are, inter alia, photos posted on Instagram. They can easily become the basis for behavioural analysis of the quality of urban life based on complete sampling and conducted in the method of deskresearch. The article uses photographs published on Instagram for the purpose of exploratory analysis of land use on the examples of five parks located in New York. This makes it possible to determine the nature and ways of perception of selected spaces.

Published: April 2020

In order to find the optimal combination of process parameters for laser cladding 304L alloy powder on the surface of 45 steel, a combination method of single factor test and multi-factor orthogonal experiment was used to perform the single pulse laser cladding experiment. The effects of process parameters (pulse current A, pulse width B, pulse frequency C,defocus distance D, scan velocity E) on the morphology and performance of cladding layer was studied by range analysis, and the optimal combination of cladding parameters is calculated by fuzzy comprehensive evaluation. The results show that different process parameters have different effects on the morphology of the cladding layer and scanning velocity E and defocus distance D are the most important influencing factor of cladding morphology. The effect on cladding width is D> C > A > B > E and the effect on cladding height is E > A > C > D > B. The optimal combination of cladding width is A4B4C4D4E2. The optimal combination of cladding high is A2B1C1D4E1. The comprehensive optimal process parameters are pulse current 210A, pulse width 3.6ms, pulse frequency 16Hz, defocus distance +10mm and scanning speed 240mm/min. The average hardness of the cladding layer, melting pool, heat-affected zone and substrate under the optimal process parameters is 406.2 HV0.5, 470.8 HV0.5, 230.5HV0.5 and 202.0HV0.5, respectively. The 304L cladding layer on 45 steel surface is stable in width, height and surface quality under comprehensive optimal parameters.

A 66-year-old women with no history of renal disease was admitted due to a coma and acute kidney injury with a serum creatinine level of 7.44 mg/dL which were ascribed to valacyclovir neurotoxicity and nephrotoxicity, respectively. She had received valacyclovir at a standard dosage for the treatment of herpes zoster and was finally discharged, having fully returned to her normal baseline mental status with a recovered serum creatinine level of 0.68 mg/dL. We feel that awareness of this pathology remains a challenge for physicians and therefore strongly recommend the further accumulation of experiences similar to our own. Our experience underscores the pitfalls of administering valacyclovir to elderly patients who barely appear to have a favorable renal function. Several concerns regarding the therapeutic management, including blood purification strategies, that emerged in this case are also discussed.
