El estudio permitió concluir que la cartografía social utilizada en la comunidad Oscar Lucero Moya logró potencializar nuevas relaciones sociales con la naturaleza, en la práctica se fortalecieron lazos de cooperación mediante la articulación de actores y se construyeron nuevos saberes que re-significaron el contexto. Además se asumió una nueva cosmosvisión desde un enfoque de sistema complejo, que favoreció el análisis de los conflictos socio-ambientales develados como problemas.
Markers of Quality in Design Precedent
Authors: Gray Colin M.
Published: September 2020

The generation and description of design precedent is at the core of design case scholarship. However, traditional standards of quality and rigor that are relevant for other types of design and scientific scholarship do not always apply equally to the generation of design cases. In this paper, I describe the nature of design precedent and the standards for evaluating precedent artifacts in a way that foregrounds access of the reader to aspects of design complexity in the design work being described. Standards of quality point towards the appropriateness and potential contribution of the precedent material to design knowledge, across the following dimensions: interest to other designers; rich representation of the design; articulation of transparency and failure; accessibility of style; and acknowledgement of complexity and scope.
The Renewal of the Socialist Ideal
Authors: Foster John Bellamy
Published: September 2020

Any serious treatment of the renewal of socialism today must begin with capitalism's creative destruction of the bases of all social existence. Since the late 1980s, the world has been engulfed in an epoch of catastrophe capitalism, manifested today in the convergence of (1) the planetary ecological crisis, (2) the global epidemiological crisis, and (3) the unending world economic crisis. Added to this are the main features of today's "empire of chaos," including the extreme system of imperialist exploitation unleashed by global commodity chains; the demise of the relatively stable liberal-democratic state with the rise of neoliberalism and neofascism; and the emergence of a new age of global hegemonic instability accompanied by increased dangers of unlimited war.

Published: September 2020

Carbonated hydroxyapatite is frequently used as bone graft material in dentistry. It is highly biocompatible, has osteoconductive properties, and functions as a drug delivery system. Propolis is a natural product from bees that has antibacterial and anti-inflammatory effects and is capable of accelerating wound healing. Incorporating propolis into carbonated hydroxyapatite was expected to enhance the wound-healing process by stimulating fibroblast growth and regenerating alveolar bone in the treatment of periodontitis. The aim of this study was to evaluate the effect of carbonated hydroxyapatite with incorporated propolis on the viability of NIH 3T3 fibroblast cells. This study used three treatment groups [carbonated hydroxyapatite with various concentrations of incorporated propolis (5%, 7.5%, and 10%)] and one control group (carbonated hydroxyapatite with no propolis). An MTT assay was carried out to assess cell viability, and absorbance readings were performed by using an ELISA reader. The data were analyzed by using one-way ANOVA. The results showed significant differences between all groups, and carbonated hydroxyapatite with 10% incorporated propolis has the highest cell viability level of all groups, while the control group has the lowest cell viability. In conclusion, adding propolis to carbonated hydroxyapatite could increase the growth of NIH 3T3 fibroblast cells. Keywords: Carbonated hydroxyapatite, Propolis, NIH 3T3 fibroblast cells, MTT assay

Menopause is a hypoestrogenic condition due to decreased function of the ovary. During menopause there is no reserved ovum in the ovary, as a result the synthesis of estrogen by the follicles does not take place. Deficiency of estrogen can lead to discomfort and decrease in the women quality of life. Therefore, supplements from natural resources to reduce menopausal symptoms will be needed. The objectives of the study were to determine the effect of mahogany seeds ethanolic extract (MSEE) on the development of uterus, bone density, and mammae gland proliferation on ovariectomized rats. Extract was made by maceration using 96% ethanol as the solvent, then the study of estrogenic effect was carried out on 30 female rats which were divided into 6 groups. Group 1 (normal control), group 2 (positive control) given estradiol dose of 0.18 mg/kg body weight (BW), group 3 (negative control) given Na-CMC 1% and group 4, 5, 6 given MSEE orally for 14 consecutive days with doses of 50, 100, 200 mg/kg BW. Data were analysed using ANOVA then continued with Tukey HSD Post Hoc test to see the differences between the treatments. The results of the study showed that MSEE was able to increase the weight of the uterus, the length of estrus phase in the estrus cycle, bone density and the mammae gland proliferation of rats. The results concluded that MSEE has phytoestrogenic effect on ovariectomized rats.Keywords: phytoestrogen, ovariectomy, uterus weight, bone density, mammae proliferation

Published: September 2020

Cervical cancer is one of the most leading causes of women death. Currently, paclitaxel is still one of the main therapeutic regimens for cervical cancer patients. However, some patients developed to be paclitaxel-resistant. Hence, studies to find out the novel strategies to resolve this problem are important. Generating resistant cancer cell lines can be utilized as the potent tool to evaluate the efficacy of any therapeutic agent toward cancer drug-resistant problems. Current studies describing the methods to establish chemoresistance are lacking. Moreover, study in Indonesia conducting chemoresistance in cell line is limited. This study was aimed to elaborate the characteristics of HeLa cells during generation of paclitaxel-resistant cervical cancer cells. The parental HeLa cells were exposed to an escalating concentration of paclitaxel for a long time period. Subsequently, cells were divided into two groups for the evaluation of resistance characteristics. The values of inhibitory concentration 50 (IC50) and inhibitory concentration 90 (IC90) were analyzed using 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) assay. Our data showed that the longer exposing periods of paclitaxel, the higher IC50 and IC90 values of HeLa cells are. IC90 of paclitaxel in HeLa Pac RB was increased from 69 pM, 440 pM, 2,561 pM and 10,337 pM on 0th, 1st, 2nd, 3rd and 4th months, respectively. Interestingly, the resistant cells were recovered to be paclitaxel-sensitive when they were not being continuously exposed to paclitaxel. In addition, the paclitaxel resistant cells become less sensitive against 5-FU but not doxorubicin, cisplatin and etoposide. We were able to generate cervical cancer HeLa paclitaxel-resistant cell line. These cell line could potentially be utilized for further studies in order to understand the molecular mechanisms of drug resistance in cervical cancer and as a tool for cancer drug discovery.Keywords: cervical cancer, drug resistant cell line, paclitaxel resistant cells, stepwise escalating concentration.

The development of geographic information accompanied by the expansion towards accumulation of the greater and greater amount of geospatial data – initiated the specific theoretical marriage of reflection on objectivizing character of the digital imago mundi and the cognitive relationship between the “state of the world” and the “state of the mind”. Whereby, electronic repositories of “geoevery- kind” data constitute the direct articulation of consciously acquiring and organising spatial data, additionally supported by the evidence of emergence of the new and inspired by “the sciences of cognition” (that is: cognitive psychology, cognitive science, philosophy of the mind, etc.) technologicalsolutions in this realm. Such a theoretically-technical amalgam of information considerably limits – and being the clue of this paper – the explanatory usefulness of digital spatial data in the sociological analysis and deforms the contemporary state of knowledge regarding spatially-driven collective behaviours, leading to the rise of the mentioned myths.

Sukcesy reaktywacji czy modernizacji linii kolejowych w Polsce powodują wzrost zainteresowania opinii publicznej oraz świata polityki tym tematem. W 2019 r. podjęte zostały dwie kluczowe decyzje dla rozwoju systemu kolejowego w Wielkopolsce. Rząd przyjął założenia programu „Kolej Plus”, w ramach którego może dojść do podłączenia do sieci kolejowej Śremu, Gostynia i Turku, a władze województwa przystąpiły do aktualizacji planu transportowego zakładającego przywrócenie ruchu do Międzychodu przez Pniewy i przez Sieraków, a także przywrócenie ruchu do Czarnkowa. W artykule przedstawiono wybrane uwarunkowania transportowe tych inwestycji. Aby inwestycje odniosły sukces, konieczne jest znaczące podniesienie maksymalnych prędkości w stosunku do historycznych parametrów oraz dopasowanie sieci stacji i przystanków do struktury osadniczej. Istniejąca oferta autobusowa służy zaspokojeniu popytu na transport uczniów. Kolej może więc pozyskać osoby korzystające na co dzień z samochodów.
Peak to average power ratio (PAPR) reduction in filter bank multicarrier (FBMC) and orthogonal frequency division multicarrier (OFDM) based visible light communication systems
Authors: Abdalla Haitham F. , Hassan Emad S. , Dessouky Moawad I.
Published: September 2020

Filter bank multicarrier (FBMC) is a new waveform candidate in the visible light communication system (VLC). FBMC is a particular sort of multi-carrier modulation that can be viewed as an option in contrast to orthogonal frequency division multicarrier (OFDM) with CP (cyclic prefix). The point is to defeat some innate disadvantages of the normally utilized optical OFDM schemes. The principles of key transceiver should be intended to suit the necessities of the channel of IM/DD. Peak to average power ratio (PAPR) and bit error rate (BER) performance of FBMC based VLC are discussed and compared with scheme of optical OFDM. FBMC based VLC system with clipping technique has the lowest PAPR and good BER performance compared to conventional system in this paper. This paper recommends that FBMC based VLC has an incredible potential for optical wireless communication systems with high-speed. Matlab program simulations confirm the analysis. The results may shed light into potential research line on FBMC based VLC systems.

What's that smell? New directions for materials studies
Authors: Newstead Sarah , Casimiro Tânia Manuel
Published: September 2020

‘Smellscapes’ have become an increasingly popular concept in recent years. Here, the authors argue for a new direction in sensorial archaeology by focusing on the ‘smell of things’ or the potential information held in the odours of archaeological objects. They offer a case study using early modern earthenware ceramics from Portugal—renowned for the distinctive smell and taste imparted to their contents—to explore the possibility of developing standardised analytical techniques and vocabularies that would allow archaeologists to describe the odours associated with artefacts.

Published: September 2020

A collaborative team of Science and Operations Officers from the National Weather Service (NWS) Weather Forecast Offices (WFOs), hydrologists from the Lower Mississippi River Forecast Center (LMRFC), and management from the Weather Prediction Center (WPC) worked together to develop and transition a tool into NWS operations called the Extreme Precipitation Forecast Table (EPFT). The EPFT was designed to help NWS
forecasters improve their situational awareness (SA) when heavy rainfall threatens their county warning area. The EPFT compares Quantitative Precipitation Forecasts (QPF) to Average Recurrence Intervals (ARIs) from the NOAA Atlas-14 to alert forecasters to the potential for climatologically significant and extreme rainfall. A counterpart to the EPFT, called the Extreme Precipitation Assessment Table (EPAT), compares observed
precipitation (i.e., Quantitative Precipitation Estimates [QPE]) to inform forecasters as to the climatological significance of impactful rain events. This paper presents cases demonstrating the usefulness of the EPFT and EPAT in helping forecasters improve their SA in real-time operational settings when heavy rain was a threat.
Corrosion Behavior of Steel Reinforcement in Chloride Admixed Self-Compacting Concrete Subjected to Different Exposure Conditions
Authors: Jain Smrati , Pradhan Bulu
Published: September 2020

Chloride-induced corrosion is one of the most significant durability problems faced by reinforced concrete structures. In this study, chloride-induced corrosion performance of steel reinforcement was evaluated in self-compacting concrete (SCC) in the presence of internal chloride. Two types of exposure condition were adopted, i.e., air curing (laboratory drying) and water curing with alternate wetting-drying cycles, till an exposure duration of 450 days. After 450 days, only water curing specimens were further exposed to 5 % sodium chloride (NaCl) solution with alternate wetting-drying cycles for another 240 days. The corrosion behavior of steel reinforcement was monitored through half-cell potential and linear polarization resistance measurements. The obtained results indicated that there is no systematic variation in corrosion potential between two exposure conditions. SCC specimens exposed to normal water curing with alternate wetting-drying cycles showed lower corrosion current density than those exposed to air curing. Ordinary portland cement (OPC)–based SCC showed better corrosion performance than portland pozzolana cement and OPC + 20 % fly ash–based SCC during an early exposure period in the presence of internal chloride; however, the opposite variation was observed during later ages after exposure to 5 % NaCl solution.

This article analyses the main legislation in Spain regarding Bilingual Education in the stage of Primary Education. Firstly, it divides Spanish regions into monolingual and bilingual. Later, it deals with the main legislation enforced in Primary Education, and carefully analyses three main aspects: teachers’ L2 level, teachers’ methodological requirements, and the non-linguistic discipline or disciplines included in bilingual programs together with the subjects’ language or languages of delivery and assessment. The first aspect, L2, is labelled following the different levels of the European Framework of Languages. As for teaching methodology, information has been classified as “not mentioned”, “recommended” or “required”. With regards to subjects, there are four different labels: “compulsory”, “optional”, “not mentioned”, and “not specified”. A high degree of heterogeneity is observed in two of the three areas analyzed. These differences among regions do not seem to be connected with their monolingual or bilingual nature. Finally yet importantly, it should be assumed that India and Spain are not close realities in some aspects. However, the study described above might help researchers, teachers or educational authorities to reflect upon some issues which are derived from CLIL(Content and Language Integrated Learning) methodology implementation in schools.

Child abuse impedes an individual personality and leaves mark on the heart of an individual eventually and affects the growth and development. The children are most vulnerable and can be easily exploits. Child Abuse refers to the action which hurt or harms children in terms physical, emotional, sexual etc. The study was intended to find out the status and perceived attitude towards the child abuse among upper primary school students of Kolhapur city. A descriptive survey was conducted and the data was collected from 221 Upper Primary School students using structured questionnaire of child abuse. The findings of study were parents do not talk about the uncomfortable situations their child might face in absence of them along with and let the child make it know about the uncomfortable situation faced by their child to the responsible adult and the child to deal with such situations at school, movie, by doctor, friend or at a workshop. This is serious concern as parents must make aware about child abuse among their wards and Most of the Boys and Girls don’t know what to do if they will have to face any of the above mentioned situations.

Authors: Shilpa Manigatta Doddagowda , Kalyani Raju , Sreeramulu P N
Published: September 2020

Introduction: The most common malignancy which endangers the quality of life in females is breast cancer. It is also the major public problem in society and despite advances in treatment strategies, it still leads to high mortality. In all breast cancer patients, the first assessment done before surgery is the complete blood count (CBC). There exists a strong relationship between immune response of the body and clinical staging of breast cancer. This study aimed to determine the most reliable hematological markers for the prognosis of breast cancer, and to evaluate the correlation between hematological parameters and disease staging.

Methods: This study was a case control study conducted for a period of 3 years from Jan 2016 to December 2018 in the Department of Pathology (R.L. hospital and Research Center attached to Sri Devaraj Urs medical college, Tamaka, Kolar, Karnataka). The comparison of the hematological parameters was done between the study group (70 cases) and the control group (20 cases). The relation between the hematological parameters and the various stages of breast cancer was analyzed before initiating the treatment.

Results: The majority of the breast cancer patients were of stage 2. The hemoglobin concentration, red blood cell (RBC) count, lymphocyte count, and were reduced in the study group, with a significant difference (p < 0.05) when compared to the controls. Hemoglobin concentration, RBC count, hematocrit, white blood cell (WBC) count, and absolute lymphocyte count were inversely proportional to the stage of breast cancer. The absolute count, ratio (NLR), and platelet-to-lymphocyte ratio (PLR) were directly proportional to the progression of disease.

Conclusion: Hemoglobin, RBC count, WBC count (including differential count), NLR, and PLR are the key hematological indicators which predict the severity and mortality risk of breast carcinoma.

Published: September 2020

OBJECTIVES:

To decrease the average length of stay (LOS) of opioid-exposed newborns (OENs) by 20% from baseline from April 2017 to December 2019.

METHODS:

The Colorado Hospitals Substance Exposed Newborn Quality Improvement Collaborative is a consortium of neonatal providers, public health experts, and legislative experts that provides infrastructure and resources for Colorado birthing hospitals to undertake initiatives focused on improving the care of OENs. The Colorado Hospitals Substance Exposed Newborn Quality Improvement Collaborative was started in September 2017 and includes 19 birthing hospitals in Colorado, with 12 contributing data to the centralized database. The interventions were focused on (1) hospital engagement and (2) increasing nonpharmacologic care (by using the Eat, Sleep, Console assessment tool; developing guidelines for breastfeeding eligibility; employing comfort measures before pharmacologic therapy; and administering opiate therapy on an as-needed basis).

RESULTS:

From April 2017 to December 2019, 787 OENs were identified. Among infants ≥35 weeks’ gestational age without other medical diagnoses (n = 647), statistical process control charts revealed significant reduction in the primary outcome of interest, average hospital LOS, from 14.8 to 5.9 days. For all OENs, receipt of pharmacologic therapy declined from 61% to 23%. Among OENs who received pharmacologic therapy (and were ≥35 weeks’ gestational age without other medical diagnoses), average LOS also declined from 21.9 to 8.0 days.

CONCLUSIONS:

Through standardization of OEN care focused on family engagement and nonpharmacologic care, this statewide collaborative reduced average LOS, the percentage of OENs requiring opiate therapy, and average LOS for OENs requiring opiate therapy.

Published: September 2020

OBJECTIVES:

The coronavirus disease 2019 (COVID-19) pandemic has fueled xenophobia against Chinese Americans. We examined the rates of 6 types of COVID-19 racism and racial discrimination experienced by Chinese American parents and youth and the associations with their mental health.

METHODS:

We recruited a population-based sample of Chinese American families to participate in this self-reported survey study conducted from March 14, 2020, to May 31, 2020. Eligible parent participants identified as ethnically/racially Chinese, lived in the United States, and had a 4- to 18-year-old child; their eligible children were 10 to 18 years old.

RESULTS:

The sample included 543 Chinese American parents (mean [SD] age, 43.44 [6.47] years; 425 mothers [78.3%]), and their children (N = 230; mean [SD] age, 13.83 [2.53] years; 111 girls [48.3%]). Nearly half of parents and youth reported being directly targeted by COVID-19 racial discrimination online (parents: 172 [31.7%]; youth: 105 [45.7%]) and/or in person (parents: 276 [50.9%]; youth: 115 [50.2%]). A total of 417 (76.8%) parents and 176 (76.5%) youth reported at least 1 incident of COVID-19 vicarious racial discrimination online and/or in person (parents: 481 [88.5%]; youth: 211 [91.9%]). A total of 267 (49.1%) parents and 164 (71.1%) youth perceived health-related Sinophobia in America, and 274 (50.4%) parents and 129 (56.0%) youth perceived media-perpetuated Sinophobia. Higher levels of parent- and youth-perceived racism and racial discrimination were associated with their poorer mental health.

CONCLUSIONS:

Health care professionals must attend to the racism-related experiences and mental health needs of Chinese Americans parents and their children throughout the COVID-19 pandemic via education and making appropriate mental health referrals.

The purpose of this study was to analyze the risk of the maxillary sinus lift technique and the correlation between the thickness of the gingiva, maxillary sinus membrane, and the maxillary sinus lateral wall. Cone-beam computerized tomograhy (CBCT) records of 32 adult dentate patients (10 male/22 female) were analyzed. The gingival thickness records of the dental units were compared with the thickness measurements of the membrane and lateral wall of the maxillary sinus. The gingival biotypes varied between 1.1 mm (thin) and 1.6 mm (thick), with a small association with sex. The thickness of the sinus membrane presented a small association between sexes (0.2 mm, female/0.3 mm, male) and gingival biotypes (Cohen d = .52). The lateral wall presented a weak association between the biotypes (1.3 mm, thin/1.1 mm, thick). There was also no correlation between the membrane and lateral wall (r = −.22). The volume dimension related to the graft area of the sinus was 4 mm3 for men and 5 mm3 for women. There was a weak correlation of gingival thickness compared with membrane thickness and lateral wall of the sinus (r = .304/r = −.31). Gingival thickness does not appear to be a reliable thickness predictor of the membrane or lateral wall of the maxillary sinus. The analysis of maxillary sinus anatomical structures through CBCT is the most reliable technique to identify the thickness of the membrane and lateral wall of the maxillary sinus before surgery. We believe that new studies are necessary to confirm our findings.

This study aimed to compare the crestal bone loss between a 2-implant–supported, noncantilevered 3-unit fixed partial prosthesis (TUFPP) with sinus augmentation and a 2-implant–supported, distal cantilevered TUFPP without sinus augmentation in the posterior maxilla having insufficient crestal bone. The study subjects were enrolled in 2 groups. Group 1 included patients with 2 implants: an anterior implant placed in the native bone and a posterior implant inserted with simultaneous sinus augmentation using a xenogenic bone graft to support a TUFPP. Group 2 included patients with 2 implants inserted in the native bone to support a distal cantilevered TUFPP. The crestal bone levels at the distal and mesial aspects of each implant were measured at baseline and 6-, 12-, and 24-month follow-up controls on panoramic radiographs. Fifty-two patients and 104 implants were included. There was a significant difference in distal crestal bone loss between anterior and posterior implants in group 1 at 6 months (P < .05) but not at 12 and 24 months (P > .05). Distal crestal bone loss was significantly increased in group 1 posterior implants compared to the group 2 posterior implants at 6 months (P < .05). There was no significant difference in mesial bone loss between the anterior and posterior implants in both groups at all follow-up controls (P > .05). There was also no significant mesial crestal bone loss in relation to the anterior and posterior implants of both groups at all follow-up controls (P > .05). Noncantilevered 2-implant–supported TUFPP with sinus augmentation may have similar medium-term crestal bone loss when compared to cantilevered 2-implant–supported TUFPP without sinus augmentation. Further prospective studies should be designed to compare the performance of the 2-implant–supported cantilevered TUFPP and 2-implant–supported TUFPP with sinus augmentation.

As the global COVID-19 pandemic advances, it increasingly impacts the vulnerable populations who already bear a heavy burden of neglected tropical diseases. Chagas disease (CD), a neglected parasitic infection, is of particular concern because of its potential to cause cardiac, gastrointestinal, and other complications which could increase susceptibility to COVID-19. The over one million people worldwide with chronic Chagas cardiomyopathy require special consideration because of COVID-19’s potential impact on the heart, yet the pandemic also affects treatment provision to people with acute or chronic indeterminate CD. In this document, a follow-up to the WHF-IASC Roadmap on CD, we assess the implications of coinfection with SARS-CoV-2 and Trypanosoma cruzi, the etiological agent of CD. Based on the limited evidence available, we provide preliminary guidance for testing, treatment, and management of patients affected by both diseases, while highlighting emerging healthcare access challenges and future research needs.

A new Coronavirus (2019-nCov, renamed SARS-CoV-2) was identified in the Chinese city of Wuhan in late 2019, and was declared a pandemic by the World Health Organization, on March 11, 2020. As it is a highly infectious disease, major regional and national changes have been made, social isolation was recommended, which led to the interruption of various services, including elective dental treatments. This review aimed to identify the changes that occurred in the post-COVID-19 orthodontic practice scenario. For such, a search was made for articles published in the bibliographic bases PubMed, Scopus and SciELO, using the keywords “Orthodontics” and “Covid-19”. From the eligibility criteria, 11 articles were selected for analysis. It was found that social isolation impacted the scheduling of orthodontic appointments and patient’s anxiety about the duration of treatments. The use of teleodontology proved to be an ally in screening and in patient care. Preventive infection control must be adopted for safe orthodontic practice.
Carbon coating of electrode materials for lithium-ion batteries

Lithium-ion batteries have become one of the most popular energy sources for portable devices, cordless tools, electric vehicles and so on. Their operating parameters are mostly determined by the properties of the anode material and, to a greater extent, the cathode material. Even the most promising electrode materials have disadvantages, such as large changes in the unit cell volume during the charge–discharge cycles, resulting in the electrode disintegration and capacity fading or low ionic or electronic conductivities. To overcome these shortcomings (destruction of materials or slow lithium diffusion), similar approaches are used, including the use of nanosize materials and the formation of composite materials with various conductive additives, the most popular of which is carbon. A small particle size causes less damage and minimises the diffusion path length, and carbon behaves as a buffer, thereby eliminating volume changes and providing a more stable contact between particles. Moreover, carbon coating of nanoparticles provides fast lithium diffusion along the interfaces. In this review, the authors summarised the recent research progress on carbon composites used in lithium-ion batteries. The theoretical foundations of electrochemical processes and some typical examples of the practical application of such composites are also outlined.

La alfabetización mediática es un conjunto de habilidades de aprendizaje referentes a la capacidad de acceder, analizar y crear una variedad de mensajes mediáticos. También la alfabetización mediática es una habilidad esencial en el mundo de hoy. Para avanzar al complejo entorno de medios de hoy, deberíamos poder comprender mejores mensajes de medios. Las personas con conocimientos mediáticos podrán descubrir los mensajes complejos que se encuentran en televisión, radio, periódicos, revistas, libros, vallas publicitarias, Internet y otros medios independientes. También pueden crear sus propios medios y participar activamente en la configuración de la cultura de los medios. En este sentido, el presente estudio ha identificado un nuevo libro sobre “Pensamiento mediático y alfabetización” en las escuelas secundarias, desde la perspectiva de los maestros, desde los aspectos de los métodos de enseñanza, incluidos los contextos, procesos, aportes y resultados. En esta investigación, el tipo de investigación es una aplicada, que se realiza por método descriptivo y encuesta. La población estadística estaba compuesta por todos los maestros del décimo nivel de la escuela en el distrito 18 de Teherán y el tamaño de la muestra se determinó usando la tabla Morgan. Después de una encuesta de docentes, análisis de datos. Los resultados con el uso de One Sample T-Test indicaron que los métodos de enseñanza de este libro fueron de medio a alto, en términos de contextos, entradas, procesos y salidas. Además, los resultados de la prueba de Friedman muestran que la prioridad más importante de los métodos de enseñanza de este libro fueron los factores contextuales, y el factor menos importante son las entradas.
La quimera de una educación sin valores
Authors: Expósito Cristián David
Published: September 2020

La escuela es el espacio real y concreto donde se cristalizan aquellos valores trazados en el diseño curricular propio de cada sistema educativo. Es aquí donde debe producirse también una interacción reflexiva que suscite el cuestionamiento de las costumbres culturales vigentes y de aquellos valores sociales y personales más convenientes para promover el bien de la comunidad. Esto conlleva la responsabilidad de plantear adecuaciones para mejorar la convivencia en sociedad sin comprometer la propia raíz cultural. El delicado equilibro entre estas variables devendrá en armonía; de lo contrario, obtendremos una crisis que generará posturas antagónicas y en el lugar de la paz solo encontraremos una brecha social. En este artículo abordaremos la profunda relación existente entre la tríada “educación, valores e ideología”; ya que toda situación escolar, sea cual fuere la postura ideológica asumida, va a estar impregnada de determinados valores que impactan en la educación de las personas por el modo en que son concebidos y plasmados en el currículum.

Entre las cuestiones metodológicas de estudiar el problema de la orfandad social, un lugar importante está ocupado por la búsqueda de marcadores efectivos para evaluar la dinámica, por un lado, y la efectividad de la política social para superar la orfandad social, por el otro. Ese intento de evaluar sistemáticamente la escala y la gravedad del fenómeno, así como los factores clave que determinan su dinámica. Sin embargo, estos enfoques no nos permiten identificar la conexión entre el trabajo social y la dinámica de mejorar la situación con la orfandad social en la región. El estudio presentado propone un nuevo modelo para evaluar la dinámica de la orfandad social. Su diferencia con otros enfoques metodológicos es que el énfasis principal está en evaluar la orientación del complejo de cambios en los procesos de identificación, colocación de huérfanos y cancelación de decisiones sobre su transferencia a las familias. Este modelo nos permite evaluar el papel de la política social en la superación de la orfandad social. En este modelo, desarrollamos métodos de autor para clasificar las regiones de Rusia por la dinámica de los indicadores integrados en el índice de "auspiciosidad" de los cambios en la orfandad social. Además, el autor presenta un modelo que evalúa la situación en la región desde el punto de vista del "índice de eficiencia del apoyo social" para superar la orfandad social. Los modelos utilizados para evaluar la dinámica de la orfandad social se han probado como una herramienta para identificar marcadores clave de la eficiencia de la política social.

Amaç: Endoblok, endodonti pratiğinde çalışma boyunun tespiti ve sürdürülmesinde yararlanılan odontometrik bir araçtır. Bu çalışmada biri yerli üretim olmak üzere 2 farklı endobloğun milimetrik olarak doğruluğunun değerlendirilmesi amaçlandı.
Gereç ve Yöntem: Mini-Endo-Bloc (Dentsply-Maillefer, Ballaigues, İsviçre) ve Resident (Kibar Dental, İstanbul, Türkiye) marka endobloklardan üçer adet alındı. Bu endoblokların cetvelleri üzerinde bulunan milimetre çizgileri (12-30 arası), doğrudan 0.01 mm hassasiyetinde bir elektronik kumpas ile ölçüldü. Eğe boyu kalibrasyon deliklerinin derinlikleri (12.0-27.5 arası) ise, lastik stoperli #40 bir eğeye transfer edilerek yine aynı kumpas ile ölçüldü. Her bir paralel beş kez ölçüldü. Her bir endoblok markasının ölçüm kalitesinin incelenmesi için istatistiksel kontrol sınırları ile spesifikasyon sınırları karşılaştırıldı. Spesifikasyon sınırları ürün üzerinde belirtilen referans değerler dikkate alınarak 3 standart sapma (sigma) genişliğinde hesaplandı. Kontrol sınırları ise, ürünün test edilmesi sırasında elde edilen ölçümlerden hesaplandı. Kontrol sınırlarının spesifikasyon sınırlarını aşması durumu hata olarak kabul edildi.
Bulgular: Mini-Endo-Bloc’un cetvelinde ve kalibrasyon deliklerinde hata görülmedi. Resident’in ise 23, 25-30 mm cetvel çizgilerinde (referans değerinin üstünde ölçümler) ve 15.0, 18.0, 18.5 ve 19.0 numaralı deliklerinde (referans değerinin altında ölçümler) istenen spesifikasyonların karşılanmadığı görüldü.
Sonuç: Mini-Endo-Bloc, cetvel ve delik ölçümlerinde istenilen kalite standardını tamamen karşıladı. Resident istenilen kalite standardını karşılamadı.
