L’imaginaire de la « poétique du Divers » et de la « Philosophie de la Relation » d’Édouard Glissant : repenser la mondialisation au prisme de la « transrhétorique »
Authors: Rhimi Mohamed Amine
Published: July 2021

Édouard Glissant, romancier, poète et philosophe antillais, s’en remet à Victor Segalen et valorise sa poétique du Divers pour saborder les bastions de l’Universalisme standardisant que cultive Saint-John Perse. Somme toute, l’écrivain s’emploie à promouvoir la transrhétorique, laquelle tient lieu de coupure épistémologique avec la culture atavique et la systématisation coloniale sous laquelle succombent les Caraïbes. Dans cette perspective, il met en jeu les différents genres oratoires (l’épidictique, le judiciaire et le délibératif), dans l’objectif de faire face à l’aliénation, issue de la philosophie occidentale de l’Histoire. C’est ainsi également que le romancier envisage réhabiliter les différents imaginaires artistiques de la totalité-monde dans l’intention non seulement de mettre en crise le régime politique injuste de la mondialisation, mais également de proposer des solutions aux fléaux terribles qui en découlent. C’est là où réside, à notre avis, l’enjeu majeur de l’imaginaire de la géopoétique de la mondialité et la portée considérable que revêt l’esthétique de la nouvelle région du monde.
Cristóbal Nonato de Carlos Fuentes : Une esthétique du chaos au service du Mexique profond
Authors: Désert Gérald
Published: July 2021

Il s’agira de montrer, au travers de quelques échantillons narratologiques significatifs tirés du roman Cristóbal Nonato de Carlos Fuentes, comment l’auteur, par le biais de l’écriture, de sa poétique du chaos, resacralise l’homme hypermoderne mexicain dans l’implexité diplomatique des sociétés postmodernes, occidentales, occidentalisées, éclatées, fractales et le triptyque des convulsions historiques : colonisation, industrialisation, globalisation. À cet effet, il sera intéressant de voir comment il arrive à susciter chez le lectorat le trésor d’images que le Mexicain porte en lui pour mieux le contempler dans sa virginité et assimiler son message vital. Comment l’imaginaire romanesque de l’auteur est au service de la reconstruction identitaire nationale profonde et est vecteur d’une conscience des masses en rupture avec les fondements de la modernité, de plus en plus ochlocratique, de plus en plus en quête d’authenticité, de liberté, d’autodétermination et de transmodernité.
Entre évitement et alliance : formes mineures du divin en Afrique et ailleurs
Authors: Kedzierska Manzon Agnieszka
Published: July 2021

Les sciences religieuses et notamment l’anthropologie ont rencontré dans leurs enquêtes des entités assez élusives, conçues et vécues comme des visions floues, éphémères, ou comme des agresseurs potentiels menaçant ceux qui pénètrent par mégarde ou obligation sur leur territoire. De telles puissances peuvent, dans certains cas, être transformées au moyen d’un culte en alliés qui s’emparent alors, pour se manifester, du corps de leurs serviteurs ou qui sont figurées à travers certains artefacts. Les conférences de l’année 2019‑2020 ont été dédiées à l’analyse de leurs conceptualisations africaines (mandingues, lobi, seme, ouatchi, bwaba, gourmantché, gbaya, hausa), mises en parallèles avec celles d’autres sociétés anciennes (Rome, Ougarit) et contemporaines (Europe, Sibérie, Népal, Amazonie).
A figura do Cristo Sofredor entre mendicantes e leigos carmelitas no Rio de Janeiro (séculos XVII-XIX)
Authors: Brusadin Lia Sipaúba
Published: July 2021

As ordens mendicantes compostas por frades vocacionados à penitência revolucionaram a espiritualidade dos núcleos urbanos no século XIII no ocidente europeu. Isso permitiu aos leigos uma maior participação na esfera religiosa, os quais deveriam seguir o mais fielmente possível os atos e sofrimentos de Jesus em uma busca pela redenção individual. O Concílio de Trento valorizou a multiplicação de associações para a difusão dos exercícios piedosos, destacando-se a devoção à Paixão de Cristo, na Europa e no ultramar. No Império Português, grande parte das igrejas da Ordem Terceira do Carmo apresentavam o programa iconográfico com representações da Via Sacra. Tal qual as congêneres portuguesas, os terceiros do Rio de Janeiro se configuraram como um eixo laico de práticas e culto aos Passos nos séculos XVII-XIX. Para a percepção daquele cotidiano secular no religioso e sua interface com a figura do Cristo Sofredor foram analisados a Regra Carmelita e os Livros de Estatutos e de Inventário da Ordem Terceira carioca, associando seu conteúdo às visões de viajantes estrangeiros a respeito dos rituais realizados, além da pesquisa e registro fotográfico in loco das esculturas de Jesus e sua Paixão. Dessa maneira, para o leigo o contato com Cristo e seus sofrimentos, por meio de acervos sacros, exercícios, cerimônias litúrgicas e festivas, conduzia a uma intimidade divina e à pretensão de uma existência edificada diante da realidade antagônica e transitória da vida.
Casa de Prisão com Trabalho em Teresina-Piauí (1850-1880)
Authors: Monteiro Gleison Costa
Published: July 2021

Esse artigo procura apresentar, no contexto da reforma prisional do império do Brasil, as ações das autoridades administrativas provinciais do Piauí para construir, ampliar e estruturar os espaços de encarceramento dos criminosos. Deste modo, utilizamos na pesquisa documentos impressos e manuscritos; são fontes como relatórios provinciais, correspondências entre as autoridades administrativas, policiais e judiciais. As análises empíricas nos revelaram um universo intricado dos homens livres e pobres no interior da província e também serviram de parâmetro para decifrarmos as formas que as autoridades engendraram para conter esse grupo nos seus quefazeres cotidianos, inclusive, encaminhando ao cárcere aqueles que julgavam desordeiros, afim de capacitá-los para o trabalho regular. Em relação aos pressupostos teóricos, nos deram suporte os seguintes autores: Chalhoub (2001), Mariz (2004), Lara e Mendonça (2006), Aguirre (2009), Dantas (2011), Albuquerque Neto e Maia (2011), Trindade (2012), Silva (2014), Cesar (2014), Britto (2018). Com este apoio documental e teórico, procuramos problematizar os discursos de que somente a privação da liberdade poderia tornar os contraventores probos para, posteriormente, serem inseridos ao convívio social. Alia-se a essa narrativa a construção de uma Casa de Prisão com Trabalho, cujo intuito era implantar oficinas no recinto penal e associá-las à instrução para a correção, no sentido de moralizar os detentos, ao mesmo tempo que se buscava com elas desonerar os cofres públicos.
Usos políticos do passado no governo Vargas: Tiradentes e a Inconfidência Mineira
Authors: Fraga André Barbosa
Published: July 2021

Apesar de estudos anteriores já terem evidenciado a importância do culto a Tiradentes ao longo do governo Vargas (1930-1945), a presente pesquisa objetiva compreendê-la especificamente a partir do discurso oficial do regime. Para isso, este artigo analisa as políticas culturais desenvolvidas pelo Ministério da Educação e Saúde (MES) e pelos órgãos de propaganda da ditadura do Estado Novo, as quais tiveram o intuito de valorizar a Inconfidência Mineira e heroificar os envolvidos nesse movimento, especialmente Tiradentes. Adotam-se como fontes principais livros produzidos pelo MES, pelo Departamento Nacional de Propaganda (DNP) e pelo Departamento de Imprensa e Propaganda (DIP). Além delas, recorre-se a jornais e a documentos localizados no Arquivo Nacional e no CPDOC/FGV. Com base na noção de “usos políticos do passado”, o artigo conclui que o MES, o DNP e o DIP foram os principais patrocinadores do culto a Joaquim José da Silva Xavier. Nas políticas culturais desenvolvidas por eles, valores atribuídos ao personagem, como coragem, patriotismo e apego à liberdade, à defesa nacional, à unidade do país e aos interesses coletivos em detrimento dos individuais, foram estimulados e despertados na população, de modo a que todos amassem o Brasil e ajudassem o governo no combate ao comunismo e aos países do Eixo. No entanto, apesar de tal valorização, o período foi marcado também por versões negativas sobre a Inconfidência, que rivalizavam com a que estava sendo construída pelo ministério de Gustavo Capanema e pelos órgãos de propaganda do governo Vargas, dando origem a batalhas de memória.

Published: July 2021

The manufacturing environment for apparel is subject to a variety of constraints, stochasticity, and unforeseen events. In order to create an accurate scheduling-system for this environment, these complexities must be considered. This article presents the development and the application of a scheduling and rescheduling decision support system for an apparel manufacturer. Furthermore, the results of applying the proposed system are presented and discussed. The scheduling and rescheduling decision support system presented in this article takes advantage of a variable neighborhood search and Monte Carlo simulation in order to minimize tardiness in the presence of different release times, sequence-based setup times, blocking, and resource constraints. The results show that the quality of the schedules generated by the proposed scheduling and rescheduling decision support system is superior to the current firm’s scheduling practice, which is based on an earliest due date heuristic. Moreover, the percentage of the realized schedule and overall equipment effectiveness were improved.

Published: July 2021

Vehicle suspension system plays a vital role in diminishing the vibration caused by the road roughness and prevent it from transmitting to the driver and the passenger. The semi-active suspensions contain spring and damping elements with variable properties, which can be changed by an external control. The work presented here is concerned with semi-active damper control for vibration isolation of base disturbances. Numerous control algorithms for semi active system had been suggested in the past, performed experimentally and validated with various computational models.In this work, the 2-DOF quarter car model with semi-active suspension, controlled by skyhook and balance logic with on-off and continuous control algorithms is being studied.The computational models are subjected to various road profiles like single half sine bump, random road disturbanceas typical Indian road scenario. So that the performance can be done as real time inputs. The simulation is being carried out on Matlab or Simulink.

Published: July 2021

In this study, the reliability of the solder joints of a six-side molded panel-level chip-scale package (PLCSP) is investigated. Emphasis is placed on the thermal cycling test (−55°C Δ 125°C, 50-min cycle) of the six-side molded PLCSP on a printed circuit board. For comparison purpose, the one without six-side molded (ordinary) PLCSP is also subjected to the same test. The thermal cycling test results are plotted into a Weibull distribution, and the true Weibull slope and true characteristic life at 90% confidence are presented. The solder joint mean life ratio of these two cases and its confidence level are also determined. Furthermore, their solder joint failure location and failure mode are provided. Finally, a nonlinear, time- and temperature-dependent 3-D finite element simulation is performed for these two cases and correlated with the thermal cycling test results.

This report releases the field datasets and analytical results from targeted surficial geology studies and till sampling completed in 2017 and 2018 in mainland Nunavut and eastern Northwest Territories as part of Natural Resources Canada's Geomapping for Energy
and Minerals (GEM?2) Rae Synthesis of Glacial History and Dynamics Activity in the interior of the Keewatin Sector of the Laurentide Ice Sheet. Fieldwork consisted of targeted mapping of glacial flow indicators to resolve the relative ice-flow chronology, sampling material for geochronology to help
reconstruct the glacial and post-glacial histories at a regional scale, and documenting the nature and composition of the glacial sediments in various glacial terrains. In addition to the field and analytical datasets, this report provides a detailed description of the field and analytical methods.
In 2017, Quaternary geological field observations were made at 92 sites; 39 till and 16 geochronology samples were collected in 5 areas in the Baker Lake and Arviat regions, Nunavut. In 2018, the focus shifted to the Healey Lake area in eastern Northwest Territories and central mainland Kitikmeot
region, Nunavut. Quaternary geological field observations were made at 72 sites; 44 till and 17 geochronology samples were collected. Till samples were analysed for matrix geochemistry and texture, gold grain counts, indicator mineral picking and probing, and pebble lithology
counts.
Determining the processes responsible for plume attenuation in an oil sands wetland
Authors: Gammon P
Published: July 2021

Data collection, whilst somewhat delayed by COVID-related lab shutdowns), continues to generate important new insights into the environmental processes and chemistry at the research site new Fort McMurray. Interpretation and modelling of inorganic geochemical
data from the site demonstrates that the plumes' boron (B) distribution is consistent with an equilibrium sorption model. The model approximates the start of the OSPW seepage at 13 years ago, which suggests seepage probably started with the establishment of the tailings pond. Unlike B, modelling of
the acid extractable organic (AEO) data indicates that the very rapid (<20 m) attenuation of the OSPW signature is unlikely to be due to sorption alone, but rather due to competitive ligand reactions that ultimately lead to carboxylic acid sequestration in the substrate. Data on
microbially-mediated AEO decomposition and seep water toxicity and toxicity evolution within the plume are pending.

Published: July 2021

The prognosis and treatment of New World tegumentary leishmaniasis is dependent on the infecting species, yet such species identification in the Leishmania Viannia subgenus poses a diagnostic challenge. Currently, speciation relies on standard molecular techniques such as restriction fragment length polymorphism (RFLP) analysis, and Sanger sequencing (SS). Whole-genome sequencing (WGS) is a robust and increasingly cost-efficient tool that may improve Leishmania species identification. We evaluated WGS versus standard RFLP-SS for species identification in three reference and five clinical strains of Leishmania Viannia spp. Internal transcribed spacer1 (its1), cysteine proteinase b (cpb), and heat shock protein 70 (hsp70) polymerase chain reaction-restriction fragment length polymorphism (RFLP) was performed, followed by SS of the its2, cpb, hsp70, and mannose phosphate isomerase (mpi) loci. After de novo assembly, sequences were mapped, and homology compared with both reference strains and reference genomes on National Center for Biotechnology Information. All American Type Culture Collection strains were confirmed to be single-species of L. V. braziliensis, L. V. guyanensis, or L. V. panamensis by WGS. Conversely, RFLP-SS was able to definitively identify one of three isolates to the species level. Clinical samples were identified as either single-species (N = 3), mixed (N = 1), or hybrid (N = 1) infections by WGS, while standard molecular diagnosis required multi-target composite analysis for identification due to loci-dependent results by RFLP-SS. We have corroborated the utility of WGS as a diagnostic tool to speciate members of the L. Viannia subgenus and to discriminate between mixed and hybrid infections. WGS is a potentially useful complement to multistaged RFLP-SS for species identification in Leishmania infections.
The Need for a Practical Approach to Evaluate the Effectiveness of COVID-19 Vaccines for Low- and Middle-Income Countries

Published: July 2021

The global demand for coronavirus disease 2019 (COVID-19) vaccines currently far outweighs the available global supply and manufacturing capacity. As a result, securing doses of vaccines for low- and middle-income countries has been challenging, particularly for African countries. Clinical trial investigation for COVID-19 vaccines has been rare in Africa, with the only randomized clinical trials (RCTs) for COVID-19 vaccines having been conducted in South Africa. In addition to addressing the current inequities in the vaccine roll-out for low- and middle-income countries, there is a need to monitor the real-world effectiveness of COVID-19 vaccines in these regions. Although RCTs are the superior method for evaluating vaccine efficacy, the feasibility of conducting RCTs to monitor COVID-19 vaccine effectiveness during mass vaccine campaigns will likely be low. There is still a need to evaluate the effectiveness of mass COVID-19 vaccine distribution in a practical manner. We discuss how target trial emulation, the application of trial design principles from RCTs to the analysis of observational data, can be used as a practical, cost-effective way to evaluate real-world effectiveness for COVID-19 vaccines. There are several study design considerations that need to be made in the analyses of observational data, such as uncontrolled confounders and selection biases. Target trial emulation accounts for these considerations to improve the analyses of observational data. The framework of target trial emulation provides a practical way to monitor the effectiveness of mass vaccine campaigns for COVID-19 using observational data.

Lightning strike damage is a real threat to these materials during service life. Along with experimental studies, their damage predictions by numerical methods are being attempted by various researchers. The numerical simulation of this damage by coupled thermal–electric (transient) analysis and thermal transient analysis is presented in this article. In this study, damage predictions based on thermal profiles are carried out, and suitable validations with earlier published work are discussed.
Long-term solubility and sorption characteristics of novel dental restoratives
Authors: Yadav Sukriti , Gangwar Swati
Published: July 2021

Sorption and solubility are the unfavorable conditions for the dental restorative composites (DRCs). It can be precursor of various physical and chemical phenomenon that may lead to structural deterioration and minimizes the endurance of restorations. This study sought to evaluate the sorption and solubility features of MPTS (M)/APTES(A) treated n-HAPs filled dental composite in distilled water and artificial saliva medium. In this experiment, 7 different compositions of disc-shaped specimens of Φ15mm×1mm (n=3) of dental composites were prepared and tested under distilled water and artificial saliva medium for 35 days according to ISO 4049 method. The dental material shows relatively higher sorption and solubility in the artificial saliva medium as compared to distilled water. However, at higher wt.% (DRCs-12M & DRCs-12A), it shows minimum solubility (i.e.) and sorption characteristics. The results indicate that there was significant variation regarding storage medium and time to saturation but still these values are within the limit of the ISO 4049 standards, which is 40 μg/mm3 for sorption and 5μg/mm3 for Solubility.

Published: July 2021

The motive of this paper is, to develop accurate and parameter uniform numerical method for solving singularly perturbed delay parabolic differential equation with non-local boundary condition exhibiting parabolic boundary layers. Also, the delay term that occurs in the space variable gives rise to interior layer. Fitted operator finite difference method on uniform mesh that uses the procedures of method of line for spatial discretization and backward Euler method for the resulting system of initial value problems in temporal direction is considered. To treat the non-local boundary condition, Simpsons rule is applied. The stability and parameter uniform convergence for the proposed method are proved. To validate the applicability of the scheme, numerical examples are presented and solved for different values of the perturbation parameter. The method is shown to be accurate of O(h2 + △t) . Finally, conclusion of the work is included at the end.

Published: July 2021

Background: Bryophyllum pinnatum is an environmental weed from the Crassulaceae family that is often used to treat convulsion, hypertension, diarrhea, insect bites, asthma and other ailments.Objectives: To evaluate the anticonvulsant potential of methanol aerial extract of Bryophyllum pinnatum plant in mice and chicks.Materials and Methods: The anticonvulsant potential was studied using Maximal electroshock Test (MEST) and pentylenetetrazol (PTZ) test in one day old chicks and mice at 250, 500 and 1000 mg/kg body weight of the extract i.p respectively. Positive control drugs used were sodium valproate (200 mg/kg) and phenytoin (20 mg/kg) in PTZ and MEST respectively while distilled water (10 ml/kg) i.p was used as negative control in all experiments.Results: The intraperitoneal LD50 of the extract was found to be greater than 5000 mg/kg body weight with an indication that the extract is relatively safe. Significant (p ≤ 0.05) prolongation of the mean onset of seizures was recorded with the extract at 1000 mg/kg body weight compared with normal saline treated group in PTZ induced seizures. Bryopyllum pinnatum methanol aerial extract also significantly reduced the mean recovery time of seizures at doses 500 and 1000 mg/kg induced by MEST when compared with normal saline treated group. Conversely, a significant (p ≤ 0.05) delay in the mean onset of seizures was recorded with standard drugs, sodium valproate (200 mg/kg) and phenytoin (20 mg/kg) in PTZ and MEST respectively.Conclusion: Methanol extract of the aerial part of Bryophyllum pinnatum possesses anticonvulsant activities.
The Influence of Inflexible Work Schedules and Land Use Design on Traffic Congestion in Kigali City
Authors: Bagenzi Lea , Alade Taslim , Muramira Sylion
Published: July 2021

Travel demand is still poorly managed in Kigali city. The other research that was done on traffic congestion in Kigali city aimed to regulate the supply side of the problem. However, this study aims to regulate the demand side of traffic congestion on Kimironko- CBD, Nyanza Kicukiro- CBD, and Gisozi- CBD roads in Kigali city where inflexibility of work schedules and land use design were presented as the main issues leading to traffic congestion. The statistical results of the study did not show any strong correlation between the independent variables and the dependent variables because of the limited number of respondents that undermined the relationships and the questionnaire data collected represented peak-period only hence social-economic variables did not show any relationship with travel time as proved by other empirical studies. However, using the data from interviews, questionnaires, ArcGIS Pro, and secondary data, the study shows that there is a significant relationship between inflexible work schedules, land use design, and traffic congestion where departure time choice, commuting distance, land use mix, and connectivity has influenced significantly travel time and level of service. All the 3 roads under study are congested where Gisozi-CBD road is the most congested and Kicukiro-CBD road is the least congested. This study supports the view that traffic congestion can not only be regulated by focusing on the supply side of traffic congestion but balancing both the demand and supply side of the problem. However, travel demand management that aims to reduce unnecessary trips is the pillar to achieve sustainable mobility which focuses on the movement of people and goods rather than the movement of cars.

Published: July 2021

Waste generated in the construction industry is a major environmental problem but its research is rather limited. Thus, this research was conducted to assess the waste disposal practices of construction companies at the Airport Hills and Sakumono areas in Accra, Ghana. These areas were chosen because of the increasing and fast development of housing projects there. A convenience sampling technique was used in choosing the companies to achieve the research goal. Questionnaires and field observations were used to gather information about the construction companies and their waste management practices. Forty construction companies were identified in both study areas. Majority of the companies recorded a total of 60-80 cubic meters of material waste per month. Eleven companies stated amounts of between USD 250 - 350 as cost of material waste management per month. Several reusable materials were identified at construction sites. Twenty-six companies practised sorting and recovery of waste before final disposal. It was revealed that there was no statistically significant relationship between the educational levels of waste management teams of the construction companies and their practice of proper waste management methods. A significant relationship however existed between the educational level of waste management teams and their use of waste management plans. It is recommended that waste management training programmes are developed by the Environmental Protection Agency of Ghana for construction companies to curb the problem of poor construction waste management.
Facile Synthesis, Characterization and in Silico Docking Studies of Novel Thiazolidine-2,4-Dione-Based Mannich Base Bearing Furan/Thiophene Moiety as Promising Anti-Inflammatory Agents
Authors: Nkurunziza Jean Baptiste , Dukuziyaturemye Pierre , Musabwa Edith , Kalluraya Balakrishna
Published: July 2021

Mannich bases are compounds bearing a β-amino carbonyl moiety. They are formed in the Mannich reaction that consists of an amino alkylation of an acidic proton placed next to a carbonyl functional group by formaldehyde and a primary or secondary amine. Mannich base products are known for their curative properties such as anti-inflammatory, antibacterial, anticancer, antifungal, anthelmintic, anticonvulsant, analgesic, anti-HIV, antipsychotic, antiviral, and antimalarial activities. Further, thiazolidinedione derivatives have shown to be efficacious in inflammatory diseases as wide-ranging as psoriasis, ulcerative colitis and non-alcoholic steatohepatitis. In light of the above observations, new series of thiazolidine-2,4-dione based Mannich base derivatives were synthesized via a simple and catalyst-free procedure involving the condensation of thiazolidine-2,4-dione, formaldehyde and secondary amines in DMF solvent. The structures of the newly synthesized compounds were confirmed by their IR, 1H-NMR, and Mass spectra. The synthesized compounds were tested for their in silico anti-inflammatory activity by Docking studies against COX-2 enzyme (PDB: 1CX2). Compounds 4a and 4b showed good in silico anti-inflammatory properties comparable to that of standard drug Diclofenac and may be considered as promising candidates for the development of new anti-inflammatory agents.

Published: July 2021

Human resources play a key role in the achievement of construction projects. This study investigated the recruitment practices of construction employers in Rwanda. The problem of the study is the lack of empirical evidence to support the recruitment and selection practices of construction employers in Rwanda. Similar studies are abundant in other sectors of the economy but very scarce in the construction industry. The descriptive survey research design was adopted for the study. A closed-ended questionnaire was used for data collection. The population of the study are the construction organisations that employ construction workers in Rwanda. Hence, the population of the study is the 580 construction organisations that are officially working in Rwanda. A sample of 80 firms used for the study were determined with the use of Slovin’s formula. The findings of the study indicated that requests for the curriculum vitae, cover letter, face-to-face interview, submission of applications with key information of education/work experience and knowledge test to measure job specific knowledge are the prevalent strategies of recruiting and selecting staff in the construction industry. The prominent sources of recruitment and selection are internship performance, internal advertisement, and local newspaper advertisement. Based on the findings of the study, it was recommended that construction organizations should study and adopt the recruitment and selection strategies that have given them the most effective results. It was also recommended that the organisation should stick to the most effective sources of recruitment and selection for their organisations

This study is a case study regarding the operation of the liberal arts curriculum based on core competencies. It was conducted to explore the developmental direction of the competency-based curriculum. The study investigated the trend in the changes of the competency-based curriculum of N University, as well as the actual conditions and demands of the faculty’ capacity-based curriculum operation.
N University's competency-based education has grown through a three-stage transformation process. The quality of education has been managed by diagnosing the effectiveness of competency-based education at the curriculum level through competency matching with the competency of the subject. While professors are highly aware of the necessity of competency-based education, they are relatively inadequate when it comes to teaching various curriculums. Therefore, for the purpose of competency-based education, it is necessary to diversify the curriculum.
The professor was engaged in the following activities to operate the competency-based curriculum: student-centered class preparation and activity-oriented teaching methods, one-on-one feedback and guidance on activity experiences, observation and activity-oriented competency evaluation, and curriculum improvement plans reflecting student opinions, etc. Through the exploration of this process of change, and based on the recognition of the professors, suggestions on educational policy, educational content, and educational methods were made.
The purpose of this study was to demonstrate that a specific case of competency-based education at a certain university, along with the perception of professors with competency-based education experience, suggests the direction in which competency-based education is heading.

Published: July 2021

The purposes of this study were to develop a checklist, which guides the process of design thinking for the students, and to analyze the case of A university, so as to facilitate the non-subject educational activities in university.
From the results of the literature review, we derived the preliminary items included in the checklist. After verifying the content validity, a Delphi survey by 15 experts was conducted. Corresponding to the five steps of design thinking, a total of 22 items, including 3 items for ‘empathize’, 6 items for ‘define’, 5 items for ‘idea’, 3 items for ‘prototype’, and 5 items for ‘test’ were finally selected for the students’ checklist.
With regard to their problem solving abilities, the design thinking based program might be beneficial for enhancing students’ competence when it comes to problem clarification and plan execution. Furthermore, the developed design thinking checklists, along with the presented case of the design thinking program, are expected to encourage students to more actively apply the design thinking process to their non-subject educational activities.
The Golden Ages of Porn: the 1970s (Translation into Russian)
Authors: Waldrep Shelton
Published: July 2021

This essay focuses on the brief moment in early seventies filmmaking when the porn industry made narrative-based films such as Deep Throat (1972) and Behind the Green Door (1972). This attempt to fuse porn with mainstream culture has come back into vogue in the present, when we see a new legitimization of porn. One might say that recent representations of sex on the screen have attempted to go back to the early seventies to restart a trajectory that was never able to complete itself. The essay begins with a consideration of the origins of porn films in nineteenth-century European art before moving on to the discussion of the seventies porn films and the complex way in which European art cinema influenced mainstream porn. Related to this topic are how cultural differences within countries influence the approach to sex that is expressed on the screen. In the US, the seventies full-length porn films legitimized certain sexual acts for their audiences and centered some of the pleasure on the screen on female desire as a way to expand the audience for porn. The essay concludes with a coda on the gay male cinematic equivalents of straight seventies porn films.

The instruments used were observation questionnaires, product validation sheets, teacher and student practice sheets, and evaluation questions based on the critical and creative thinking indicators. The results of the analysis of pretest and post-test evaluation questions obtained that the mean of N-gain was 0.4 for critical thinking and Ngain was 0.5 for creative thinking. These two thinking skills had moderate N-gain scores. The results of the critical thinking t test showed that t arithmetic (0.036) < t (0.05) and creative thinking skills t test showed that t arithmetic (0.000) < t (0.05). Thus, it indicates that guided inquiry-based LKPD are effective for improving the students’ critical and creative thinking skills.
PSYCHOLOGICAL PROBLEMS AMONG RETIRED PEOPLE IN SELECTED URBAN AND RURAL – A REVIEW
Authors: kaur mrs rajwant , chauhan Dr Krishna , chauhan Dr Krishna
Published: July 2021

ABSTRACT
Retirement is the act of retiring or the state of being retired, i.e. to withdraw oneself from business, public life or
and to remove from active service. However, it is important to recognize that retirement as a single life event is
rarely the cause of these outcomes. Perhaps people with greater work ethic might be more prepared for
retirement and might feel it to be their “just reward” for their years of hard work. Also found that retirees who had
higher entrepreneurial orientations were more likely to engage in career bridge employment than in full
retirement, whereas retirees who had more desire to pursue a new career were more likely to engage in bridge
employment in a different field than in full retirement. A significantly negative relationship was found between
loneliness, depression, hopelessness and income. Conclusion shows that institutionalization might lead to poor
mental health.
