Tessituras de memórias: o Instituto Fernandes Figueira pelo olhar geracional / Interweaving memories: the Fernandes Figueira Institute through a generational perspective

Resumo Recuperamos memórias do Instituto Fernandes Figueira via o cuidado que reúne crianças doentes e suas mães. A categoria analítica geração sustenta o argumento do instituto como espaço de experiências e memórias. Interpretamos três fontes de memórias: (1) a pesquisa de Marismary Horsth De Seta com a geração que chegou no instituto na década de 1940; (2) o relatório de atividades do instituto de 1973; (3) três entrevistas com trabalhadores admitidos na década de 1980. Concluímos que o cuidado com as crianças e, por conseguinte, um olhar para as mulheres nessa relação se dão em sintonia com a transição epidemiológica global, complexificando o perfil da atenção do instituto.

Abstract Memories of care involving sick children and their mothers at the Fernandes Figueira Institute (Instituto Fernandes Figueira) are retrieved. The analysis using a generational perspective reveals the institute as a space of experiences and memories. Three sources of memories are analysed: (1) the research by Marismary Horsth De Seta with the generation that reached the institute in the 1940s; (2) the institute's 1973 activity report; (3) three interviews with workers admitted in the 1980s. It is concluded that care for children, and therefore interest in their mothers, is aligned with the global epidemiological transition, increasing the complexity of the profile of care given at the institute.

Potencial transmisión congénita de la enfermedad de Chagas en la segunda generación de jóvenes embarazadas que asistieron a su control prenatal en el departamento de Cordillera, Paraguay

Trypanosoma cruzi es el agente causal de la enfermedad de Chagas. En Paraguay se estima que existen 165.000 personas infectadas y actualmente la principal vía de transmisión es la congénita, con una prevalencia del 5% y con alrededor de 400 niños infectados nacidos por año. El departamento de Cordillera es área endémica de la Región Oriental del país, donde se implementó el Programa de Control Prenatal de Chagas en el año 1995. El objetivo de este estudio fue inferir sobre la potencial transmisión congénita de la enfermedad de Chagas en jóvenes embarazadas de segunda generación de Cordillera que asistieron a su control prenatal en el período 2010-2012, 15 años después de la implementación del Programa de Control Prenatal. De 9.588 embarazadas; 482 fueron seropositivas (5%); 2,74% en el grupo de 12 a 19 años, 4,93% de 20 a 30 años, 8,03% de 31 a 40 años y 16,11% de 41 a 48 años. Para estimar el origen de la transmisión congénita de segunda generación se tuvo en cuenta a las 72 seropositivas de 12 a 19 años y según la base de datos de las respectivas madres 61 eran seropositivas. Con esta información se estima que la transmisión a embarazadas de segunda generación de 12 a 19 años fue congénita en un 85% indicando una transmisión congénita muy significativa en la población de estudio. Esta información ayudaría al Programa Nacional de Chagas en el fortalecimiento del control de la transmisión congénita de la enfermedad de Chagas en el país.

Trypanosoma cruzi is the causative agent of Chagas disease. In Paraguay, it is estimated that 165,000 people are infected and currently the main route of transmission is the congenital one, with a prevalence of 5% and about 400 infected children are born per year. The Department of Cordillera is an endemic area of the Eastern Region of the country, where the Chagas Prenatal Control Program was implemented in 1995. The aim of this study was to infer the potential congenital transmission of Chagas disease towards second generation pregnant women from the Department of Cordillera who attended their prenatal control in the period 2010-2012, 15 years after the implementation of the Prenatal Control Program. Of 9,588 pregnant women; 482 were seropositive (5%); 2.74% in the group aged 12 to 19 years, 4.93% aged 20 to 30 years, 8.03% aged 31 to 40 years, and 16.11% aged 41 to 48 years. To estimate the origin of second generation congenital transmission, the 72 seropositive women aged 12 to 19 years were taken into account and according to the database of their respective mothers, 61 mothers of the 72 were seropositive. With this información, it can be estimated that 85% of the transmission to second generation pregnant women aged 12 to 19 years was congenital showing a very significant congenital transmission in the study population. This information could help the National Chagas Program in strengthening the control of congenital transmission of Chagas disease in the country.

The Value Generation of College Students’ Responsibility Ethics in Major Public Emergencies / 中国医学伦理学

The outbreak of major public emergencies is an important practical issue that affects social development and human survival and security. In the face of major public emergencies, college students in the new era must have a strong sense of responsibility and mission. This paper took the formation value of college students’ responsibility ethics as a logical clue, deeply analyzed the subject-object function relationship of college students’ responsibility ethics in major public emergencies, and combined the philosophy of subjectivity to reveal the contradictory connotations of college students’ subjects, that is, the contradictory relationship between spontaneity and consciousness, selfishness and dedication, passivity and initiative, and relyed on the connotation logic of responsibility ethics to promote the sense of responsibility and mission of college students in major public emergencies, so that they can develop to a higher level, thus realizing the ultimate goal of generating the value of responsibility ethics.

Application of metagenomic next-generation sequencing in prevention and control of infection in solid organ transplantation / 器官移植

Organ transplantation has become an effective treatment for multiple end-stage diseases. However, the recipients of organ transplantation need to take immunosuppressive drugs for a long time after operation, which leads to low immune function and relatively high incidence of bacterial, viral and fungal infections. Traditional microbial detection methods, such as pathogen culture, immunological detection and polymerase chain reaction, have been widely applied in infection detection, whereas these methods may cause problems, such as long detection time and presumed pathogens. Metagenomic next-generation sequencing has been widely adopted in infection prevention and control in organ transplantation in recent years due to high detection rate and comprehensive detection of pathogen spectrum. In this article, the application of metagenomic next-generation sequencing in the prevention and control of infection in solid organ transplantation was reviewed, aiming to provide reference for the diagnosis and treatment of transplantation-related infection.

Knowledge Graph Enhanced Transformers for Diagnosis Generation of Chinese Medicine / 中国结合医学杂志

Chinese medicine (CM) diagnosis intellectualization is one of the hotspots in the research of CM modernization. The traditional CM intelligent diagnosis models transform the CM diagnosis issues into classification issues, however, it is difficult to solve the problems such as excessive or similar categories. With the development of natural language processing techniques, text generation technique has become increasingly mature. In this study, we aimed to establish the CM diagnosis generation model by transforming the CM diagnosis issues into text generation issues. The semantic context characteristic learning capacity was enhanced referring to Bidirectional Long Short-Term Memory (BILSTM) with Transformer as the backbone network. Meanwhile, the CM diagnosis generation model Knowledge Graph Enhanced Transformer (KGET) was established by introducing the knowledge in medical field to enhance the inferential capability. The KGET model was established based on 566 CM case texts, and was compared with the classic text generation models including Long Short-Term Memory sequence-to-sequence (LSTM-seq2seq), Bidirectional and Auto-Regression Transformer (BART), and Chinese Pre-trained Unbalanced Transformer (CPT), so as to analyze the model manifestations. Finally, the ablation experiments were performed to explore the influence of the optimized part on the KGET model. The results of Bilingual Evaluation Understudy (BLEU), Recall-Oriented Understudy for Gisting Evaluation 1 (ROUGE1), ROUGE2 and Edit distance of KGET model were 45.85, 73.93, 54.59 and 7.12, respectively in this study. Compared with LSTM-seq2seq, BART and CPT models, the KGET model was higher in BLEU, ROUGE1 and ROUGE2 by 6.00-17.09, 1.65-9.39 and 0.51-17.62, respectively, and lower in Edit distance by 0.47-3.21. The ablation experiment results revealed that introduction of BILSTM model and prior knowledge could significantly increase the model performance. Additionally, the manual assessment indicated that the CM diagnosis results of the KGET model used in this study were highly consistent with the practical diagnosis results. In conclusion, text generation technology can be effectively applied to CM diagnostic modeling. It can effectively avoid the problem of poor diagnostic performance caused by excessive and similar categories in traditional CM diagnostic classification models. CM diagnostic text generation technology has broad application prospects in the future.

Investigation of the molecular genetic causes of non-syndromic primary ovarian ınsufficiency by next generation sequencing analysis

ABSTRACT Objective: The aim of this study is to investigate the molecular genetic causes of non-syndromic primary ovarian insufficiency (POI) cases with the gene panel based on next generation sequencing analysis and to establish the relationship between genotype and phenotype. Subjects and methods: Twenty three cases aged 14-40 years followed up with POI were included. Patients with a karyotype of 46, XX, primary or secondary amenorrhea before the age of 40, with elevated FSH (>40 IU/mL) and low AMH levels (<0.03 ng/mL) were included in the study. Molecular genetic analyzes were performed by the next generation sequencing analysis method targeted with the TruSightTM Exome panel. Results: Median age of the cases was 17.8 (14.0-24.3) years, and 12 (52%) cases admitted before the age of 18. Fifteen (65%) patients had consanguineous parents. In 2 (8.6%) cases, variants detected were in genes that have been previously proven to cause POI. One was homozygous variant in FIGLA gene and the other was homozygous variant in PSMC3IP gene. Heterozygous variants were detected in PROK2, WDR11 and CHD7 associated with hypogonadotropic hypogonadism, but these variants are insufficient to contribute to the POI phenotype. Conclusion: Genetic panels based on next generation sequencing analysis technologies can be used to determine the molecular genetic diagnosis of POI, which has a highly heterogeneous genetic basis.

Silage quality and bacterial diversity of silages inoculated with Listeria monocytogenes and Lacticaseibacillus paracasei_6714

Introduction: King grass (Cenchrus purpureus (Schumach.) Morrone, syn. Pennisetum purpuphoides) and pineapple peel (Ananas comosus) silages are food alternatives for livestock in conditions of feed shortage. Objective: To describe the dynamics of the microbiota present in king grass and pineapple silage during the fermentation process using next generation sequencing (NGS) and to evaluate the protective effect of Lacticaseibacillus paracasei_6714 as a silage inoculum against Listeria monocytogenes. Methods: We used an unrestricted randomized design to characterize the microbiota present in silages made from king grass harvested 70 days after regrowth and pineapple peel. We inoculated mixtures of grass and peel with L. paracasei_6714 or L. monocytogenes, or both, with a non-inoculated treatment as control. The nutritional and fermentative profile was evaluated after 30 days. After 15 and 30 days of fermentation, we used 16S rRNA analysis to determine the dynamics and diversity of the microbiota in the inoculated and control silages. Result: Dry matter content and digestibility did not differ significantly; however, there were differences in crude protein, pH and organic acids. We obtained 4432 amplicon sequence variants of Proteobacteria, Firmicutes, Bacterioidetes, Actinobacteria, Verrucomicrobia, Planctomycetes and Patescibacteria. The relative abundance of each phylum varied depending on the material and fermentation period. Phylum similarity was over 70 % (but not greater than 50 % with Bray-Curtis at the species level). Conclusion: These bacterial communities seem to have an important role during silage fermentation. Proper management of silage processing can reduce or eliminate pathogenic bacteria.

La abundancia relativa de cada filo vario dependiendo del material y periodo de fermentación. Similitudes de filo fueron mayores al 70 % (pero no mayor que 50 % con Bray-Curtis a nivel de especie). Conclusión: Estas comunidades bacterianas parecen cumplir un papel importante durante la fermentación del ensilaje. Un manejo apropiado del proceso de ensilaje puede reducir o eliminar baterías patogénicas.

Effects of environmental stability and phycoperiphyton structure on the macroinvertebrate community of regulated Andean rivers / Efectos de la estabilidad ambiental y estructura del ficoperifiton en la comunidad de macroinvertebrados en ríos andinos regulados

Introduction: The variability in the structure of aquatic communities is frequently attributed to environmental changes; however, in stable environments such as regulated rivers, trophic interactions could be another key environmental factor determining the structure of these communities. These alterations could cause a greater growth of algae, and in turn, changes in the functional groups and in the composition of the macroinvertebrate community favoring the dominance of certain groups of organisms. Objective: To identify the effects of environmental variations and changes in the structure of the phycoperiphyton on the macroinvertebrate community of regulated Andean rivers. Methods: We analyzed environmental and biological data collected in quarterly samples carried out between 2010 and 2018 in two rivers of the Central Andes (Antioquia - Colombia), for a total of 27 samples. Sample collections used standardized methods. Different statistical models were used to establish spatial and temporal patterns of the environmental variables, of the abundance and/or density and diversity of phycoperiphyton and macroinvertebrates, as well as the trophic relationships that exists between them. Results: We found that regulated rivers present relatively little environmental variability. The environmental parameters with the greatest variation were temperature, turbidity, and orthophosphates; these last two were the abiotic variables with the greatest contribution to benthic instability. Conclusion: The presence of scraping and foraging macroinvertebrates was more affected by the stability of the phycoperiphyton density than by environmental variables, showing the importance of trophic interactions in regulated rivers and the bottom up control in these ecosystems.

Introducción: La variabilidad en la estructura de las comunidades acuáticas se atribuye frecuentemente a cambios ambientales, no obstante, en ambientes estables como ríos regulados, las interacciones tróficas podrían ser otro factor ambiental clave determinante de la estructura de estas comunidades. Estas alteraciones podrían provocar un mayor crecimiento de algas y, a su vez, cambios en los grupos funcionales y en la composición de la comunidad de macroinvertebrados favoreciendo la dominancia de determinados grupos de organismos. Objetivo: Identificar el efecto de los cambios ambientales y de la estructura del ficoperifiton sobre la comunidad de macroinvertebrados de ríos Andinos regulados. Métodos: Se analizaron datos ambientales y biológicos recolectados en muestreos trimestrales realizados entre 2010 y 2018 en dos ríos de los Andes Centrales (Antioquia - Colombia), para un total de 27 muestras. La recolección de muestras empleó métodos estandarizados. Se utilizaron diferentes modelos estadísticos para establecer patrones espaciales y temporales de las variables ambientales, de la abundancia y/o densidad y diversidad de ficoperifiton y de los macroinvertebrados, así como las relaciones tróficas que existen entre ellos. Resultados: Se encontró que los ríos regulados presentan relativamente poca variabilidad ambiental. Los parámetros ambientales con mayor variación fueron: temperatura, turbidez y ortofosfatos; las dos últimas variables abióticas fueron las que más aportaron a la inestabilidad bentónica. Conclusión: La presencia de macroinvertebrados raspadores y recolectores fue más afectada por la estabilidad de la densidad del ficoperifiton que por las variables ambientales, evidenciando la importancia de las interacciones tróficas en ríos regulados y el control bottoom up en estos ecosistemas.

Clinicopathological and molecular analyses of uterine carcinosarcomas using next-generation sequencing: A single-center experience

Background: Uterine carcinosarcomas (UCS) constitute 3–4% of all uterine malignancies and 16% of deaths caused due to uterine neoplasms. Aim: In this study, we aimed to perform DNA-based mutation analysis in 12 genes (KRAS, NRAS, EGFR, C-KIT, BRAF, PDGFRA, ALK, ERBB2, ERBB3, ESR1, RAF1, PIK3CA) to determine the molecular subtypes of UCS using next-generation sequencing (NGS) in patients with aggressive UCS and poor prognosis. We aimed to compare the results of our analysis with clinicopathological data to contribute to the development of targeted therapy approaches related to the molecular changes of UCS. Materials and Methods: In this study, we included 12 cases diagnosed with uterine carcinosarcomas and examined the changes in oncogenes that play a role in UCS pathogenesis. For the analysis of mutation, the clinicopathological data were compared with the variations in the DNA-based gene panel consisting of 12 genes and 1237 variants in the UCS using the NGS method. Results: EGFR mutation was found in 91.7% of the cases, mutation in 41.7%, PDGFRA mutation in 25%, KRAS and PIK3CA mutation in 16.7%, and C-KIT mutation in 8.3% of the cases. Although no statistical significance was found between the detected mutation and clinicopathological data, it was concluded that PDGFRA mutation might be associated with advanced-stage disease development. Conclusion: This study's findings regarding different molecular types of UCS and information on oncogenesis of UCS can provide inferences for targeted therapies in the future by identifying targetable mutations representing early oncogenic events and thereby contribute toward further studies on this subject.

NGS studies have become a tool in daily practice for the care of a significant number of patients in our hospital. We will continue working to expand its application to as many diseases as possible, through the existing institutional mechanisms (AU)

Next-generation sequencing-based genetic testing and phenotype correlation in retinitis pigmentosa patients from India

Purpose: Inherited retinal dystrophies (IRD) are a heterogeneous group of retinal diseases leading to progressive loss of photoreceptors through apoptosis. Retinitis pigmentosa (RP) is considered the most common form of IRD. Panel?based testing in RP has proven effective in identifying the causative genetic mutations in 70% and 80% of the patients. This is a retrospective, observational, single?center study of 107 RP patients who had undergone next?generation sequencing?based targeted gene panel testing for IRD genes. These patients were inspected for common phenotypic features to arrive at meaningful genotype–phenotype correlation. Methods: Patients underwent complete ophthalmic examination, and blood was collected from the proband for DNA extraction after documenting the pedigree. Targeted Next Generation Sequencing (NGS) was done by panel?based testing for IRD genes followed by co?segregation analysis wherever applicable. Results: Of the 107 patients, 72 patients had pathogenic mutations. The mean age of onset of symptoms was 14 ± 12 years (range: 5–55). Mean (Best Corrected Visual Acuity) BCVA was 6/48 (0.9 logMAR) (range 0.0–3.0). At presentation, over one?third of eyes had BCVA worse than 6/60 (<1 logMAR). Phenotype analysis with the gene defects showed overlapping features, such as peripheral well?defined chorioretinal atrophic patches in patients with CERKL, PROM1, and RPE65 gene mutations and large macular lesions in patients with RDH12 and CRX gene mutations, respectively. Nummular or clump?like pigmentation was noted in CRB1, TTC8, PDE6A, and PDE6B. Conclusion: NGS?based genetic testing can help clinicians to diagnose RP more accurately, and phenotypic correlations can also help in better patient counselling with respect to prognosis and guidance regarding ongoing newer gene?based therapies.

Abstract Escherichia coli is one of the main human pathogens causing different hospital- and community-acquired infections. During the period from January 2013 to March 2015, 1.96% (32/1632) of E. coli isolates recovered at the Hospital Regional de Ushuaia, Tierra del Fuego province, were resistant to third-generation cephalosporins (TGCs). These isolates were resistant to cefotaxime (91%) and/or ceftazidime (28%). No resistance to carbapenems was detected. Twenty-six isolates were positive for blaCTX-M gene, grouped as CTX-M-1/15 (54%); CTX-M-9/14 (25%); CTX-M-2 (17%); and CTX-M-1/15 plus CTX-M-9/14 (4%). Five TGC-resistant strains were positive for blaCMY gene, while one strain harbored TEM-19 ESBL. Twelve isolates were identified as ST131 E. coli hyperepidemic clone, and one as ST69. Genome sequence analysis of seven blaCTX-M-15 E. coli selected isolates confirm the circulation of ST131, ST617 and ST405 international high-risk clones in the city of Ushuaia.

People with high emotional intelligence (EI) feel a sense of association and belongingness. A person's emotional intelligence is their ability to comprehend and cope with dif?cult and complex situations in life. By overcoming stress, EI can enhance productivity. An analysis of the relationship between Emotional Intelligence and Academic Stress is presented in this paper

Molecular characterization & recombination analysis of complete enterovirus-88 isolated from acute flaccid paralysis cases in India

Background & objectives: Focus on non-polio enteroviruses (NPEVs) causing acute flaccid paralysis (AFP) due to myelitis has increased with the containment of the poliovirus. Enterovirus-B88 (EV-B88) has been associated with the AFP cases in Bangladesh, Ghana, South Africa, Thailand and India. In India, EV-B88 infection was linked to AFP a decade ago; however, to date, no complete genome has been made available. In this study, the complete genome sequence of EV-B88 was identified and reported from two different States (Bihar and Uttar Pradesh) in India using the next-generation sequencing technique. Methods: Virus isolation was performed on the three AFP suspected cases as per the WHO-recommended protocol. Samples showing cytopathic effects in the human Rhabdocarcinoma were labelled as NPEVs. Next-generation sequencing was performed on these NPEVs to identify the aetiological agent. The contiguous sequences (contigs) generated were identified, and reference-based mapping was performed. Results: EV-B88 sequences retrieved in our study were found to be 83 per cent similar to the EV-B88 isolate from Bangladesh in 2001 (strain: BAN01-10398; Accession number: AY843306.1). Recombination analyses of these samples demonstrate recombination events with sequences from echovirus-18 and echovirus-30. Interpretation & conclusions: Recombination events in the EV-B serotypes are known, and this work reconfirms the same for EV-B88 isolates also. This study is a step in increasing the awareness about EV-B88 in India and emphasizes future studies to be conducted in the identification of other types of EV present in India.

ON-CHIP PLANER WAVEGUIDES FOR SUPERCONTINUUM GENERATION IN THE MID-IR REGION OF ELECTROMAGNETIC SPECTRUM: A REVIEW

On-chip planer optical waveguide-based sources for supercontinuum (SC) generation have become highly attractive devices in the twenty-first century. Mid-IR SC sources in the 2-20 ?m wavelength region are advantageously used for gas sensing, high-sensitivity molecular detection, security, and industrial applications. These integrated photonic devices are cost-effective, scalable, and robust, and also offer more flexibility in tailoring the dispersion characteristics relative to other SC generation techniques. This article reviews the evolution of SC sources from fiber-based devices to optical waveguide-based devices and presents a historical as well as recent progress in various types of on-chip optical waveguides with physical mechanisms involved in generating coherent SC sources.

Efficacy of bupropion and cognitive behavioral therapy in the treatment of methamphetamine use disorder: a systematic review and meta-analysis

Objectives: We assessed the efficacy of cognitive behavioral therapy and bupropion compared to cognitive behavioral therapy alone for methamphetamine use disorder. Methods: The selection criteria for this systematic review study with meta-analysis were randomized clinical trials on the efficacy of cognitive behavioral therapy and bupropion in the treatment for methamphetamine use disorder (assessed by urine metabolites). The search was conducted in PubMed, PubMed Central, LILACS, SciELO, Cochrane Library, SCOPUS, Google Scholar, Ovid Medline, Clinicaltrials.gov, and the International Clinical Trials Registry Platform. The primary outcome was relapse. Risk of bias was assessed with the RoB 2 tool. The results of each clinical trial were input into an Excel spreadsheet. We performed a meta-analysis using relative risk and a 95%CI. Results: Of the 597 initial articles (498 after removing duplicate records), five were included in the meta-analysis, with an aggregate sample of 539 patients. An overall relative risk of 0.91 (95%CI 0.78-1.05) was estimated for relapse. Conclusion: Our study limitations included publication bias and heterogeneous populations. We found no evidence that cognitive behavioral therapy and bupropion reduced the risk of relapse compared to cognitive behavioral therapy and placebo.

Gene mutation profiling and clinical significances in patients with renal cell carcinoma

Abstract Objectives The pathological mechanisms of patients with Renal Cell Carcinoma (RCC) remain defined. This study aimed to evaluate relationships between the landscape of gene mutations and their clinical significance in RCC patients. Methods Tissue and peripheral blood samples of 42 patients with RCC were collected and performed for the Next Generation Sequencing (NGS) with Geneseeq PrimeTM 425-gene panel probes. Their landscapes of gene mutation were analyzed. We also carried out an evaluation of Tumor-Node-Metastasis (TNM) staging, RENAL nephelometry score, surgery, and targeted drug treatment of patients. Then we compared the correlations of landscape in gene mutations and the prognosis. Results The most common gene alternations, including BAP1, PBRM1, SETD2, CSF1R, NPM1, EGFR, POLE, RB1, and VHL genes, were identified in tissue and blood samples of 75% of patients. EGFR, POLE, and RB1 gene mutations frequently occurred in relapsed and metastatic patients. BAP1, CCND2, KRAS, PTPN11, ERBB2/3, JAK2, and POLE were presented in the patients with > 9 RENAL nephelometry score. Univariable analysis indicated that SETD2, BAP1, and PBRM1 genes were key factors for Disease-Free Survival (DFS). Multivariable analysis confirmed that mutated SETD1, NPM1, and CSF1R were critical factors for the Progression Free Survival (PFS) of RCC patients with target therapy. Conclusions Wild-type PBRM1 and mutated BAP1 in patients with RCC were strongly associated with the outcomes of the patient. The PFS of the patients with SETD2, NPM1, and CSF1R mutations were significantly shorter than those patients without variants.

The Data Generation Mechanism: Relationship Between Constructs and Their Indicators / O Mecanismo de Geração de Dados: Relação entre Construtos e seus Indicadores

Abstract The choice of statistical data analysis should be guided by a critical analysis that supports the theoretical relationship between the construct and its indicators. This theoretical article reviews the three main existing psychometric paradigms and their proposals for explaining the relationship between indicators and their constructs. The discussion begins with the standard paradigm that guides the construction and analysis of data in psychology, reflective model. Then, a description of the formative models is performed and finally the Network Analysis as an alternative. The definitions, consequences, and limitations of the use of each measurement model are presented such as a reflection on making decisions about which data generation mechanisms are more appropriate.

A discussão é iniciada com o paradigma padrão que guia a construção e análise de dados na psicologia, os modelos reflexivos. Em seguida, é realizada uma descrição dos modelos formativos e, por fim, a proposta da Análise de Redes como alternativa. São apresentadas as definições, consequências e limitações do uso de cada modelo de medida, bem como uma reflexão na tomada de decisão sobre quais mecanismos de geração de dados são mais apropriados.

A diversidade, as idades, as gerações: das especializações medíocres aos estudos necessários para a Sociologia da Juventude / Diversity, ages, generations: from mediocre specializations to necessary studies for Youth Sociology

Resumo: O objetivo deste artigo é adentrar algumas produções sobre as juventudes e as gerações, tendo como fundamento para análise a decadência ideológica, cunhada por Georg Lukács. Com isso, pretendo afirmar que as bases de algumas especializações contribuem para a disseminação de conceitos pautados por expressões da questão social atribuídas aos sujeitos individualmente, numa espécie de afirmação de essência de sujeito, que carrega determinabilidade, ou seja, estão impregnados de uma ontologia depreciativa do humano.

Abstract: The objective of this article is to enter some productions about youth and generations, having as basis for analysis the ideological decadence, coined by Georg Lukács. With this I intend to affirm that the bases of some specializations contribute to the dissemination of concepts guided by expressions of the social issue attributed to the subjects individually, in a kind of affirmation of subject essence, which carries determinability, i.e., are impregnated with a depreciative ontology of the human.

Exploring occupational hazards and protective strategies in power generation enterprises / 中国职业医学

Currently, power generation in China is dominated by thermal power, wind power, nuclear power, and hydropower enterprises. The power source mainly comes from thermal power generation. The occupational hazards in thermal power station are noise, high temperature, power frequency electric fields, dust, and chemical toxins and so on, with noise and dust (silica and coal dust) being the primary factors. The occupational hazards in wind power station are noise, power frequency electric fields, high temperature, low temperature, and chemical toxins (sulfur hexafluoride, toluene, styrene, etc.), with noise and power frequency electric fields being the major concerns. The occupational radiation hazards in nuclear power station are gamma rays, beta rays, X-rays, neutrons, alpha rays, and radioactive aerosols. There is special attention in radiation protection but not enough protection in non-radioactive hazards such as noise, high temperature, and ammonia. The occupational hazards in hydropower station are noise, power frequency electric fields, vibration, radon and its de-composites, and chemical toxins, with noise and power frequency electric fields being the primary hazards. Different categories of power generation enterprises should identify key hazards and work site for occupational disease prevention and control based on the features of occupational hazards. Improving occupational health management and protection levels are essential measures.
