El rol de los estados nacionales en el marco de la pandemia de COVID-19. Una mirada a nuestra América Latina
Authors: Lavolpe Francisco
Published: May 2020

En América Latina, el ingreso per cápita de las personas del decil más rico es varias veces superior en comparación con los deciles de menores ingresos; la desigualdad en la región se muestra estructural. A pesar de que en la última década hubo avances significativos, en esta región aún conviven millones de personas viviendo en la pobreza. El COVID-19 llega ahora a un territorio que, mientras lucha contra la pobreza y la desigualdad, aún alberga viejos huéspedes: como el sarampión, la malaria, la tuberculosis y el dengue, y dramas sociales aún no resueltos. En este trabajo se abordan algunos de los enormes retos que debe afrontar la comunidad internacional en el marco de la reciente pandemia por Coronavirus.
Od empatii do sprawczości. Jak kształtować wrażliwość młodzieży we współczesnej szkole?
Authors: Pławecka Katarzyna Maria
Published: May 2020

Celem artykułu Od empatii do sprawczości. Jak kształtować wrażliwość młodzieży we współczesnej szkole? jest refleksja nad kondycją współczesnej „polityki wrażliwości”, u podstaw której znajduje myślenie o człowieku połączone ze znanym przekonaniem, że: „nic, co ludzkie, nie jest nam obce”.

Tematyka rozważań koncentruje się na potrzebie kształcenia (rozwijania) wrażliwości humanistycznej młodzieży (szkolnej i akademickiej), żyjącej w globalnym świecie. Wrażliwość traktowana jest jako: 1) naczelne zadanie szkolnej edukacji polonistycznej, 2) ważna wartość i potrzebna kompetencja społeczno-kulturowa.

Ukazany został związek między pojęciem empatii a bardziej pojemną kategorią wrażliwości. Rozważania teoretyczne „oświetlono” propozycjami działań, skierowanych szczególnie na praktyczną realizację tematów współcześnie „niemodnych”, tj.: starości, choroby, cierpienia, samotności. Uchwycony został także paradoks świata XXI wieku, zdominowanego przez konsumpcjonizm i wygodę, w którym spotkanie z drugim człowiekiem (w duchu empatii i wrażliwości) może dostarczyć młodym ludziom wiele – wymiernych korzyści osobistych.
Lektura szkolna jako nośnik wartości. Na przykładzie powieści Johna Ronalda Reuela Tolkiena „Hobbit, czyli tam i z powrotem”
Authors: Wójcicka Edyta
Published: May 2020

Celem artykułu jest próba ukazania wybranych strategii dydaktycznych związanych z wprowadzaniem uczniów w świata wartości, których nośnikiem są omawiane na lekcjach języka polskiego lektury. Problem ten został omówiony na przykładzie powieści fantasy J.R.R. Tolkiena Hobbit, czyli tam i z powrotem. Badania nad recepcją tej książki w Polsce przez współczesnych nastolatków oraz moje doświadczenie związane z omawianą problematyką stały się motywacją do opisania kilku – jak sądzę ciekawych – strategii postępowania z tą lekturą w edukacji polonistycznej w ujęciu aksjologicznym.

Authors: Morawska Iwona
Published: May 2020

The article is a voice in the discussion on the changes entailed by the new reform of the Polish education system (introduced as of the 2017/2018 school year). An important part of it is the process of the cultural and literary education of 4–8th graders described in the core curriculum, who are described as representatives of the generation of “screen readers”. The assumed perspective enabled the author to present the possible directions of educational activities in the face of the developmental and socio-cultural needs of pupils growing up under the major impact of modern media and technology. The proposed solutions offer examples and encouragement for interpretative, reflective and creative reading and implementation of the binding core curriculum.
Sensitivity Analysis of Mathematical Model of Coronavirus Disease (COVID-19) Transmission
Authors: Resmawan Resmawan , Yahya Lailany
Published: May 2020

The study was aimed to introduce a new model construction regarding the transmission of Coronavirus Disease (henceforth, COVID-19) in human population. The mathematical model was constructed by taking into consideration several epidemiology parameters that are closely identical with the real condition. The study further conducted an analysis on the model by identifying the endemicity parameters of COVID-19, i.e., the presence of disease-free equilibrium (DFE) point and basic reproduction number. The next step was to carry out sensitivity analysis to find out which parameter is the most dominant to affect the disease’s endemicity. The results revealed that the parameters 𝜂, 𝜁𝑠𝑒, 𝛼,, and 𝜎 in sequence showed the most dominant sensitivity index towards the basic reproduction number. Moreover, the results indicated positive index in parameters 𝜂 and 𝜁𝑠𝑒 that represented transmission chances during contact as well as contact rate between vulnerable individuals and exposed individual. This suggests that anincrease in the previous parameter value could potentially enlarge the endemicity of COVID-19. On the other hand, parameters 𝛼 and 𝜎, representing movement rate of exposedindividuals to the quarantine class and proportion of quarantined exposed individuals, showed negative index. The numbers indicate that an increase in the parameter value could decrease the disease’s endemicity. All in all, the study concludes that treatments for COVID-19 should focus onrestriction of interaction between individuals and optimization of quarantine.
Bouveret’s Syndrome: A Case Report and a Brief Literature Review
Authors: Peixoto Rita , Correia Joana , Soares Mário Guimarães , Gouveia António
Published: May 2020

Bouveret’s syndrome is a rare cause of gastric outlet obstruction. We report a case of a 68-year-old woman admitted with upper digestive obstruction. A few months later, and after several diagnostic tests and clinical surveillance, a cholecystoduodenal fistula was suspected. During exploratory laparotomy, the diagnosis of Bouveret’s syndrome was confirmed and a pyelolithotomy, pyloroplasty and a cholecystectomy were performed. The patient was asymptomatic 7 months after the operation. This syndrome represents only 1% - 3% of all cases of gallstone ileus, being more frequent in women and in the elderly. The presentation is quite nonspecific, but in most cases the symptomatology suggests an upper digestive occlusion. Treatment can be achieved by lithotripsy, but most patients require a surgical approach.

A trajetória da escola isolada rural paulista no período republicano e a influência do ruralismo pedagógico
Authors: Jesus Adriana do Carmo de , Bezerra Maria Cristina dos Santos
Published: May 2020

Ao longo deste artigo trataremos da escola rural primária no período republicano e de sua associação com o modelo de escola multisseriada e unidocente denominada escola isolada – termo que se torna mais usual no fim do século XIX. Essa associação não se origina nesse trabalho, há autores importantes que já escreveram sobre o assunto e é com eles também que travaremos nosso diálogo para apreender o conceito de escola isolada rural. Em nossas análises abordaremos a relação entre café, ferrovia, coronelismo e escola, bem como a influência do ruralismo pedagógico no contexto educacional da época. Identifica-se que a organização dos serviços públicos ou de utilidade coletiva, sobretudo no que concerne à educação primária, era feita à revelia da zona rural. Nesse sentido, por mais que as escolas primárias rurais fossem criadas por meio de decretos em todo interior paulista, havia pouca, ou nenhuma, garantia de que elas, de fato, chegassem a ser instaladas.
O discurso político brasileiro sobre o nexo pedagógico entre cinema e educação (1910-1930)
Authors: Faheina Evelyn Fernandes Azevedo
Published: May 2020

Este artigo é uma exposição sintética de uma pesquisa situada no campo da Análise Arqueológica do Discurso (AAD), amparada em Michael Foucault (2012), que visa investigar o discurso sobre o nexo pedagógico entre o cinema e a educação no Brasil nas três primeiras décadas do século XX. O recorte temporal adotado é apenas uma indicação do momento no qual a defesa do cinema como recurso auxiliar do ensino despontou na sociedade brasileira, o que não vale como mera delimitação cronológica de um período. A descrição do discurso investigado se detém no entrecruzamento com a modalidade discursiva política. Ela é a responsável por trazer à tona uma série de enunciados, signatários da ordem discursiva analisada, que consiste na defesa do cinema como recurso facilitador da educação, construtor da identidade, promotor da civilização e do desenvolvimento nacional.
La universidad como resistencia
Authors: Magalhães Solange Martins Oliveira , Fortunato Ivan , Mena Juanjo
Published: May 2020

Este artículo tiene como objetivo principal analizar la organicidad entre la crisis de la universidad pública y la de sus profesores, para entender su efecto sobre la función social de ambos. A partir del referencial teórico materialista histórico-dialéctico, los autores enfatizam que la opción epistemológica puede ser teóricamente asociada al mantenimiento del control social, o a la su resistencia, al justificar intenciones y objetivos colocados a la educación. Los autores asumen, dessa forma, la epistemología de la praxis como una categoría emancipatoria contra la hegemonía, cuyos principios son propositivos en el enfrentamiento de las fuerzas reguladoras actuales y en la resistencia a nuevos “estilos de vida” hegemónicos, insertados en sus funciones sociales.

Heart rate measurement is unique and uncontrollable by any human being.Objective: This research aims to learn student’s actions by monitoring the heart rate. In this paper, we are measuring the student reaction and action in classroom can give impact on teacher’s way of delivery when in the teaching session. In monitoring, student’s behavior may give feedback whether the teaching session have positive or negative outcome.Methods: The method we use is K-Means algorithm. Firstly, we need to know the student’s normal heartbeat as benchmark. We used Hexiware for collecting data from students’ hear beat. We perform the classification where K is benchmark students’ heartbeat. K-Means algorithm performs classification of the heart rate measurement of students.Results: We did the testing for five students in different subjects. It shows that all students have anxiety during the testing and presentation. Its consistency because we tested 5 students with mixes activities in the classroom, where the student has quiz, presentation and only teaching.Conclusion: Heart rate during studying in the classroom can change the education world in improving the efficiency of knowledge transfer between student and teacher. This research may act as basic way in monitoring student behavior in the classroom. We have tested for 5 students. Three students have their anxiety in classroom during the exam, presentation, and question. Two students have normal rate during the seminar and lecturer. The drawback, Hexiware is capturing average of ten minutes and tested in different classes and students. In future, we need just measure one student for all the subjects and Hexiware need to configure in one minute.

Optimal Evolution of the Standard Genetic Code
Authors: Yarus Michael
Published: May 2020

The Standard Genetic Code (SGC) exists in every organism known on Earth. SGC evolution via early unique codon assignment, then later wobble, yields coding resembling the near-universal code. Below, later wobble also creates an optimal route to accurate codon assignment. This assignment time matches a previous mean time for ordered codes, exhibiting ≥ 90% of SGC order. Accurate evolution is also accessible, sufficiently frequent to appear in populations of 103 to 104 codes. SGC-like coding capacity, code order and assignments therefore arise together, in one attainable evolutionary intermediate. Examples, which plausibly resemble coding at evolutionary domain separation, are characterized.
Novel Polybasic Cleavage Site in SARS-CoV-2 Genome Is Likely to Induce a Major Change in the RNA Secondary Structure
Authors: Manzourolajdad Amirhossein , Xu Zhenming , Ebrahimi Diako
Published: May 2020

Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS-CoV-2) has claimed nearly 180,000 lives and continues to spread. There are currently no approved medications or vaccines for this new coronavirus. Studies have shown that the positive RNA genome of SARS-CoV-2 contains unique features, including a 12-base sequence inserted between the two subunits of viral receptor protein Spike. This inserted sequence facilitates the cleavage of Spike by the cellular proteases Furin and TMPRSS2, leading to the fusion of virus and host cell membranes. Current studies are mostly focused on the SARS-CoV-2 Spike protein and its interacting cellular proteins ACE2, Furin, and TMPRSS2. RNA structural studies are limited and little is known about the potential impact of the 12-base sequence insert on the secondary structure of SARS-CoV-2 genomic RNA and/or its transcripts. Here, by using local and global RNA secondary structure predictions, we show that the novel 12-base insert of SARS-CoV-2 genome likely induces a major RNA secondary structure change.
Why Does COVID-19 Disproportionately Affect the Elderly?
Authors: Mueller Amber L. , McNamara Maeve S. , Sinclair David A.
Published: May 2020

The severity and outcome of coronavirus disease 2019 (COVID-19) largely depends on a patient’s age. Over 80% of hospitalizations are of those over 65 years of age with a 23-fold greater risk of death. In the clinic, COVID-19 patients most commonly present with fever, cough and dyspnea. Particularly in those over 65, it can progress to pneumonia, lung consolidation, cytokine release syndrome, endotheliitis, coagulopathy, multiple organ failure and death. Comorbidities such as cardiovascular disease, diabetes, obesity and hypertension increase the chances of fatal disease, but they alone do not explain the variability in COVID-19 symptoms. Here, we present the molecular differences between the young, middle-aged and elderly that may determine whether COVID-19 is a mild or life-threatening illness. We also discuss several biological age clocks that could be used in conjunction with genetic tests to identify both the mechanisms of the disease and individuals most at risk. Finally, based on these mechanisms, we discuss treatments that could increase survival in the elderly, not simply by inhibiting the virus, but by restoring patients’ ability to clear the infection.

Published: May 2020

Electric vehicles is in rapid development. The energy commonly used as a driving force for electric vehicles comes from batteries. The development of electric vehicle technology is currently concentrated on efforts to charge the battery used by utilizing the power wasted when braking electrically. The gearbox and final drive are installed as a mechanical transmission system for electric vehicles to increase the torque of the BLDC motor as the main driving force of the vehicle. The regenerative process occurs when the Kelly-KBL motor controller electric braking feature is activated. For this reason, Arduino Mega and LabVIEW software are used to observe the current and voltage of lead acid batteries with voltage 48 V and capacity 225 Ah (C20). In addition, a 2 kW BLDC motor RPM was also observed in the electric braking monitoring system. From the results of monitoring and data collection, the vehicle traveled a distance of 36.06 m in 68 s time intervals with an average speed of 16.8 m / s. The average torque value when electric braking on a BLDC motor supplies 154 Nm, while the average torque of the vehicle is 996.99 Nm. The average regenerative power of the wheels is 17.07 kW, while the average mechanical power of the wheels is 13.67 kW. Coulometric state of charge (SOC) shows an increase in battery capacity of 4.27% and 99.97% voltage SOC at the beginning of the activation of the electric brake pedal. Maximum battery power movement when charging, 2.25 kW is caused by the activation of the electric brake pedal. Whereas when using a maximum of 1.52 kW. The application of electric braking has a power consumption efficiency of 0.042%. and charging power charging 18.97%.

In this study, we propose a new algorithm to solve the rectangular strip packing problem (RSPP), a variant of the cutting stock problem in which the mother materials have a common fixed width and infinite length. Based on the column-generation technique with three improvements, the proposed algorithm can solve large-scale problems involving tens of thousands of materials within a reasonable time, considering practical cutting constraints, i.e., the three-stage guillotine cutting constraint and the limitations of slitter blades. The proposed algorithm is evaluated in terms of its packing efficiency and calculation time.
Thermal Error Minimization of a Turning-Milling Center with Respect to its Multi-Functionality

Published: May 2020

Achieving high workpiece accuracy is a long-term goal of machine tool designers. Many causes can explain workpiece inaccuracy, with thermal errors being the most dominant. Indirect compensation (using predictive models) is a promising thermal error reduction strategy that does not increase machine tool costs. A modeling approach using transfer functions (i.e., a dynamic method with a physical basis) has the potential to deal with this issue. The method does not require any intervention into the machine tool structure, uses a minimum of additional gauges, and its modeling and calculation speed are suitable for real-time applications that result in as much as 80% thermal error reduction. Compensation models for machine tool thermal errors using transfer functions have been successfully applied to various kinds of single-purpose machines (milling, turning, floor-type, etc.) and have been implemented directly into their control systems. The aim of this research is to describe modern trends in machine tool usage and focuses on the applicability of the modeling approach to describe the multi-functionality of a turning-milling center. A turning-milling center is capable of adequately handling turning, milling, and boring operations. Calibrating a reliable compensation model is a real challenge. Options for reducing modeling and calibration time, an approach to include machine tool multi-functionality in the model structure, model transferability between different machines of the same type, and model verification out of the calibration range are discussed in greater detail.
Les médiamorphoses de Chloé Delaume
Authors: Profizi Alexandra
Published: May 2020

Chloé Delaume se pose en « personnage de fiction pire que les autres » car elle refuse de s’incarner dans un livre, prenant, au gré de ses médiamorphoses, différentes enveloppes corporelles et textuelles, présentées comme autant d’hôtes successifs. Entre expérimentations sur le texte et sur elle-même, et distorsion des réalités tangibles et virtuelles, tous les moyens, et surtout tous les médias, sont nécessaires pour atteindre la mission qu’elle attribue à son écriture : modifier le réel. Comment la parole se développe-t-elle à travers cette démultiplication de supports médiatiques et diégétiques autour du récit de soi? À partir de plusieurs de ses œuvres autofictionnelles ainsi que de son utilisation des ressources numériques, il s'agit de voir si l’écriture de Chloé Delaume, qui joue à parcourir les possibilités médiatiques de son époque, peut nous éclairer sur son projet de réappropriation de l'identité.

« Vous êtes toujours là? Ma souris m’a lâché » : cris, chuchotements et objets de l’écrivain dans le roman Vacuum de Christian Mistral
Authors: Buglea Diana
Published: May 2020

Le roman Vacuum (2003) de Christian Mistral se fait l’écho à notre époque de deux obsessions majeures : celle de la technologie et celle de se dire. Nous allons montrer que dans ce texte, qui a pris d’abord la forme d’un journal (éponyme) en ligne, l’utilisation du dispositif informatique (outil de communication privilégié en ce début de nouveau millénaire) et la manipulation de la matière du journal (support de l’œuvre à venir) sont le mobile d’un régime émotionnel chez le narrateur – un écrivain abandonné par sa muse qui raconte et commente son quotidien alors que son livre en chantier tarde à se concrétiser. Dans l’attente des mots justes et dociles, cet exutoire, vacuum extractor est salutaire : convié dans son « Bunker » où l’ordinateur, Memory Babe, a pris la place d’une vieille Underwood, le lecteur apprend la complicité de la nouvelle machine, l’épuisement de cette magie et le changement de destin du livre qui peine à mûrir.

Published: May 2020

This study analyses the subaltern that represented by Deeti in Amitav Ghosh’s Sea of Poppies. The subject of the subaltern as an Indian woman is struggling against patriarchy in society. This study uses the postcolonialism theory, including the theory of subaltern to analyze the representation of the subaltern subject who fights against patriarchy. That subject represented by Indian women as the subject of the subaltern. The narration of Deeti in the first Trilogy Sea of Poppies by Amitav Ghosh is the main focus of this study. This study using postcolonialism theory from Homi K. Bhabha and Gayatri Chakravorty Spivak, then subaltern theory also using Gayatri Chakravorty Spivak which describes how 'colonialized subject' lives and theories from Sylvia Walby and Gerda Lerner for the definition of patriarchy. So, this study mainly about how patriarchy will be related to Deeti as the subaltern explained by Gayatri Chakravorty Spivak. The data will be taken from many aspects such as dialogues, a depiction of the situation, characters, etc. This study analyzed two problems, which are (1) How is subalternity represented in Amitav Ghosh’s Sea of Poppies? (2) How do Indian Women’s struggle to fight against patriarchy in Sea of Poppies by Amitav Ghosh? The results of this study show that Subaltern represented by Indian Women. Then the struggle of Deeti as an Indian Woman and the other characters fights against the patriarchy.
Hidroterapia en neonatología. Una revisión sistemática
Authors: Torró Ferrero Galaad , Fernández Rego Francisco Javier
Published: May 2020

Introducción: Las mejoras en la atención neonatal han aumentado la tasa de supervivencia de los bebés prematuros y de bajo peso al nacer, sin embargo, la incidencia de trastornos del desarrollo y motores en estos bebés se ha mantenido casi sin cambios. Las alteraciones fisiológicas en esta población contribuyen a aumentar sus problemas de desarrollo.
Objetivo: La hidroterapia puede mostrar algunos beneficios para mejorar el desarrollo de los bebés prematuros, hospitalizados en las unidades neonatales, aportándoles una estimulación táctil y cinestésica desgravitada.
Método: Se realizó una revisión sistemática entre los meses de septiembre y noviembre de 2019, para determinar qué beneficios se pueden obtener de la hidroterapia en bebés prematuros ingresados en las unidades neonatales siguiendo los criterios PRISMA. Las bases de datos consultadas fueron PubMed, PEDro, Web of Science, CINHAL, SciELO, Cochrane Library y PsycINFO.
Resultados: Tras seguir los criterios de identificación, cribado e idoneidad quedaron incluidos en nuestra revisión para su análisis un total de 4 artículos. En ellos se analizaron las siguientes variables: dolor, calidad y duración del sueño profundo, saturación de oxígeno, frecuencia cardíaca y respiratoria, niveles de cortisol en saliva y pronóstico neurológico evaluado con los movimientos generales (MG).
Conclusiones: La hidroterapia puede contribuir a la reducción de los efectos nocivos que las unidades neonatales provocan en los bebés, promocionando su desarrollo neurológico. En este sentido, podría introducirse en los protocolos fisioterápicos de intervención y manejo de los bebés prematuros en las unidades neonatales.

Published: May 2020

Background: Simulation-based education (SBE) with high-fidelity simulation (HFS) offers medical students early exposure to the clinical environment, allowing development of clinical scenarios and management. We hypothesized that supplementation of standard pulmonary physiology curriculum with HFS would improve the performance of first-year medical students on written tests of pulmonary physiology.Methods: This observational pilot study included SBE with three HFS scenarios of patient care that highlighted basic pulmonary physiology. First-year medical students’ test scores of their cardio-pulmonary curriculum were compared between students who participated in SBE versus only lecture-based education (LBE). A survey was administered to the SBE group to assess their perception of the HFS.Results: From a class of 188 first-year medical students, 89 (47%) participated in the SBE and the remaining 99 were considered as the LBE group. On their cardio-pulmonary curriculum test, the SBE group had a median score of 106 [IQR: 97,110] and LBE group of 99 [IQR: 89,105] (p<0.001). For the pulmonary physiology subsection, scores were also significantly different between groups (p<0.001).Conclusions: Implementation of supplemental SBE with HFS could be an adequate technique to improve learning enhancement in preclinical medical students.

Background: This study aimed to translate the English version of the supportive care needs scale of head and neck cancer patients (SCNS-HNC) questionnaire into Mandarin and to test its reliability and validity.Methods: The Mandarin version of the Supportive Care Needs Survey Short-Form (SCNS-SF34) and SCNS-HNC scales were used to assess 206 patients with head and neck cancer in Chengdu, China. Among them, 51 patients were re-tested 2 or 3 days after the first survey. The internal consistency of the scale was evaluated by Cronbach's alpha coefficient, the retest reliability of the scale was evaluated by retest correlation coefficient r, the structural validity of the scale was evaluated by exploratory factor analysis, and the ceiling and floor effects of the scale were evaluated.Results: The Mandarin version of the SCNS-HNC had Cronbach's alpha coefficients greater than 0.700 (0.737 ≤ 0.962) for all of the domains. Except for the psychological demand dimension (r=0.674) of the SCNS-SF34 scale, the retest reliability of the other domains was greater than 0.8. Three common factors were extracted by exploratory factor analysis, and the cumulative variance contribution rate was 64.39%. Conclusions: The Mandarin version of the SCNS-HNC demonstrated satisfactory reliability and validity and is able to measure the supportive care needs of Chinese patients with head and neck cancer.Clinical registration number: ChiCTR1900026635

Background ： It has been acknowledged that the intervertebral disc degeneration(IDD) is associated with an aberrant cell-medicated response to structural failures, such as vertebral burst fracture, radial fissures, and endplate fracture. However, whether a momentary impact injury of the endplates without structural disruption is sufficiently to initiate disc degeneration remains elusive. This study was to further evolve an in vitro momentary impact injury model of IDD and to investigate if a momentary impact load of the endplates without structural disruption could initiate IDD.

Methods. Rats spinal segments (from L1/2 to L5/6, n=54) were harvested and randomly assigned into three groups: Control (n=18), Low Impact (12 J/cm 3 , n=18) and High Impact (25 J/cm 3 , n=18). Samples in both of the impact groups were subjected axial momentary impact load using a custom-made apparatus, and cultured for 14 days. The degenerative process was investigated by using histomorphology and real-time PCR.

Results: The discs in both of the impact groups showed significant degenerative changes at 14 days, both of which showed much higher histological scores and up-regulation of the catabolic (MMP-9, MMP-13) genes transcription than that of the control group ( P ＜0.05). The discs with endplate fracture compared to that with intact endplate also showed strongly up-regulated catabolic (MMP-9, MMP-13) genes transcription, and more significant degenerative changes based on the histological scoring ( P ＜0.05).

Conclusion: This study demonstrated that a momentary impact load (12 J/cm 3 ) on the spinal segments of the rats could initiate IDD at 14 days after injury and not only endplate fracture but also a momentary impact injury without structural disruption could also promote IDD.

Authors: Dai Shuang , Li He
Published: May 2020

Background: The object of this experimental study is a new lipase screened from metagenomic libraries in the early stage of the laboratory and named it LIP 906. In order to improve the stability of the enzyme and develop and apply it as soon as possible, experiments use directed evolution and immobilization.Results: A random mutation library was constructed by error-prone PCR technology, and finally a mutant lipase LIP 5-D with improved enzyme activity was screened out and then immobilized. Compared with the wild-type lipase LIP 906, the enzyme activity of the mutant enzyme LIP 5-D increased 4 times; the optimum reaction temperature was increased by 4 °C by mutation and 3 ℃ by immobilization; and the optimum reaction pH is changed from 7.8 to 7.5; temperature stability and pH stability has been improved. The mutant enzyme LIP 5-D can maintain a relative enzyme activity of about 70% at a temperature below 65 °C for 2 hours, and can also maintain a relative enzyme activity of about 60% at different pH 3 -10.Conclusions: Error-prone PCR and immobilization improved the catalytic activity and stability of the enzyme, and promoted its development and application in many industries. The research on the properties and modification of the new lipase LIP906 provides a solid foundation for my next innovative research in application and environmental protection.

Background

Adolescence is a period of life when prevalence of overweight, obesity and chronic non-communicable diseases rise the fastest. This period of life is very important for adoption of healthy lifestyle habits. Those include regular physical activity and diet, which could prevent nutrient deficiencies and may limit harmful behaviors contributing to the epidemic of non-communicable diseases in adulthood. There are a small number of surveys on a large number of high school and student population about this topic in low-to middle income countries.
Methods

The aim of this study was to examine dietary habits and frequency of physical activity and presence of non-communicable diseases in immediate family. Survey was conducted in 6 secondary schools of city of Mostar through an anonymous questionnaire. The study involved 482 adolescents (279 boys and 203 girls) aged 17 and 18. For data entry and analysis SPSS (version 25) was used. Association between variables was determined using chi-square.
Results

Collected data showed low breakfast consumption by adolescents, low everyday consumption of vegetables, fruits, and dairy products. There is a high trend of daily consumption of meat, especially processed meat as also as relatively high consumption of soft drinks. In addition, data showed difference in physical activity of boys and girls.
Conclusion

There were significant deviations in dietary habits of participants compared with health needs recommended for adolescent population. Therefore, it is necessary to develop and organize better nutritional education for adolescents and involve wider community to implement public health programs in order to adopt a healthier lifestyle for adolescents.
