Published: December 2022

The deterioration of ride comfort in ultra-compact vehicles has recently become an increasing concern. Active seat suspension was proposed to improve the ride comfort of ultra-compact vehicles. An active seat suspension is a vibration control device that is easily installed. The general vibration control system of the active seat suspension is fed back to the displacement and velocity by integrating the measured seat acceleration. This control has problems, such as control delay and deviation by integration. In this study, we focused on vibration control using acceleration directly. First, we established a control model that feeds back the acceleration to terminate the error occurring in the integral process and investigated the change in vibration characteristics in the case where the feedback gain of acceleration was changed. Second, the control system was analyzed to investigate the performance of the control based on the frequency characteristics. As a result, it was confirmed that the frequency response changes when the feedback gain is changed. In acceleration feedback control, ride comfort was improved by selecting a proper feedback gain because the characteristics of frequency were changed by the gain.

Published: December 2022

This study determined the risk factors of keratoconus (KC) among secondary school students in the West Region of Cameroon. A stratified, random sampling technique was used to select the 3015 secondary school students, 8 years and older, within the West Region of Cameroon. Selected school students completed the validated Keratoconus Risk Investigative Survey (KRIS) and a structured demographic questionnaire to determine the risk profile of KC. Descriptive analysis, logistic regression and p-values were used to provide an overview of the demographic findings and the risk factors of KC. Estimates were made as the proportion of affected school students and presented with a 95% confidence interval (CI). Multivariate logistic regression analysis was performed to explore the association between KC and the independent predictors that were found significant in the univariate analysis. The ages of the majority (93.2%) of students ranged from eight years to 18 years (mean = 13.18 ± years) and were mostly female (59.7%). Gender (OR 2.024, p < 0.001), eye rubbing (OR 3.615, p < 0.001), exposure to sunlight (OR 2.735, p < 0.001), blood relations with KC (OR 41.819, p < 0.001) and allergic experience (OR 1.070, p < 0.001) were considered. Eye rubbing was the most significant risk factor of keratoconus followed by refractive error, allergic experiences and sunlight exposure. These findings support the evidence that the etiology of KC is multifactorial, with eye rubbing being the most significant factor in this cohort. There is a need to address eye rubbing among students to minimize the risk of KC. Furthermore, 34.46% of students in Cameroon were at risk of developing KC. Hence the risk profile is that one engages in eye rubbing, has a family member with KC, spends more than eight hours per week in the sun and is prone to allergies. It will therefore be prudent for these risk factors for keratoconus to be included in the school health education programs.

The challenges faced by managers of transportation systems in developing nations such as Nigeria are numerous. These include driver scheduling, which, in many cases, is still being done manually; diversion of vehicles to unauthorized routes by drivers for selfish reasons results in illegal use of fuel meant for official duties, causing the organization lose considerable revenue. In its drive to reduce its carbon footprint, Elizade University, Nigeria, is embarking on the development and use of electric vehicles (EV) as a means of transportation within the university campus. This research is geared towards supporting this initiative by developing an EV tracking system that combines tracking of EV drivers with vehicle position and battery power (energy) tracking in order to mitigate the challenges outlined above. Personnel tracking was achieved using an RFID-enabled staff identity card that authenticates authorized drivers before activating the vehicle ignition system, position tracking was achieved using a geographical positioning system (GPS), and current and voltage sensors were used for tracking of electric vehicle power. Tests revealed that the EV system administrator operated through a personal computer was able to track the EV driver, position and power through a web interface/Google Maps and e-mail in real time. Whereas previous studies either considered tracking of vehicle position or power without personnel, others tracked personnel with less emphasis on the vehicle position or energy. In this study, we combined different technologies such as RFID, GPS and power sensors to consider EV administration in a holistic manner, thereby providing intervention in an infrastructurally deficient setting.

Authors: Mikkelsen Bent Egberg
Published: December 2022

Food waste is a major problem, and it is estimated that 1/3 of all food is wasted. The climate crisis has fuelled an interest in looking for solutions as well as increased interest from youth to take action. School plays an important role here. The research goal was to explore that role in developing young people’s engagement with food system change. The challenge of food waste was used as a case to create new solutions, while at the same time to create learning. The YouFoo Club program was used for the study and included 4 schools. It built on Project Based Learning, the Knowledge Triangle, and the concepts of 21st century skills; took advantage of scientific and digital principles; ran for 8 weeks; and concluded on International Food Waste Day. A sample of schools was recruited, the process was structured as a case competition, and the end goal was to present the solutions at the final event. The research shows that it is possible to bring youth into solution making, that the process contributed to learning, and that it fitted well with principles of Education for Sustainable Development. The following were found to be drivers: understanding evidence and knowledge, insight into digital technologies, the possibility of being able to work with mentors and role models, the possibility of participating in external projects, the setting of clear performance-oriented end goals, and the understanding of the importance of developing science communication skills.

Due to the wide use of rubber components in different engineering applications such as vibration isolators, engine mounts, car tires, and bridge bearing pads, etc. This rubber component mostly subjected to high levels of vibration and noise which are among the most reasons that lead to the failure of the structures. In the present paper has been performed experimentally to investigate the influences: different content ratios of natural rubber (NR) and polybutadiene (BR.cis) rubber blends [1: (50/50) %, 2: (60/40) %, 3: (70/30) %, 4: (80/20) %, 5: (90/10) %, 6: (100/0) % pphr], and two carbon blacks types (N375, and N220) on the dynamic properties (Rebound Resilience, Damping Time, and Decay Rate). The experimental results showed that the rubber compound that has the blending ratio [1: (50/50) %] has high resilience (low damping), high damping time and high displacement for two carbon black types used in this work. While these properties were improved whenever the rubber blend close to the percentage [5: (90/10) %]. The damping time, amplitude, and resilience of a rubber compound with a blending (90/10) % and carbon black (N220) are decreased by (24.53 %, 36.854 %, and 36.852 %), respectively, compared with a rubber blend that has the blending ratio of (50/50) %.

Authors: Firmansyah Bagus , Chotijah Umi
Published: December 2022

Evaluation of teacher performance at MI Bani Hasyim Cerme still uses the manual method. Using office applications such as excel and word results in a significant accumulation of data that makes it difficult for school principals to calculate scores and evaluate the results of clustering or teacher performance scores, so it is wasteful of energy, time, and cost. The k-Means clustering method is expected to facilitate the clustering process of teacher performance values ​​as a source of information and make it easy for school principals to classify teacher performance results. This research aims to obtain clustering values ​​on teacher performance assessment data and to replace the teacher performance assessment system at MI Bani Hasyim, which was previously carried out conventionally into a web-based system. The results of this study are the clustering values ​​of teacher performance assessment and a web-based teacher performance appraisal system. It is expected to facilitate the process of evaluating teacher performance in the Bani Hasyim primary school in the future.

Customer reviews of products are collected by Unified Computing System (UCS). It is a data-based computer server that is set up for evaluating hardware, programme management, and visualisation support. We employ Machine Learning algorithms to learn, evaluate, and identify customer information and data for the product based on previous customer feedback. We employ the Support Vector Machine (SVM), which is critical in dividing textual and hyper textual content into given groups. The SVM approach is useful for image classification, text reorganization, and handwriting character reorganization. We discovered that ML outperforms the other methods based on the results. When opposed to the other methods, the HRS (Human Resource System) that is proposed has a higher MAPE value of 96 percent and accuracy of nearly 98 percent. The proposed HRS has a mean absolute error of approximately 0.6, indicating that the system's efficiency is excellent.
Sulapa Eppa: Bissu, Kosmologi Bugis, dan Politik Ekologi Queer
Authors: Triadi Feby , Ismoyo Petsy Jessy
Published: December 2022

Various discourses about locality and indigenous peoples emerged as an effort to overcome the climate crisis. This term is also a part of seeing the sustainability of nature. This paper departs from arguments such as queer ecological studies and the indigenous paradigm. Furthermore, some of these academic studies are used to foster focus through indigenous knowledge in recalibrating the God-Human-Nature relationship through Bugis cosmology and the role of the Bissu. The main argument in this paper is to present Bugis knowledge and understand the embodied resistance in the existence of Bissu in South Sulawesi. This study used a qualitative method with participant observation and in-depth interviews. Data collection was carried out in two steps, namely, literature study, which was followed by participant observation and in-depth interviews. Data is then collected, classified, and interpreted through the indigenous paradigm as an effort to decolonize knowledge. The results of this study show some holistic, cyclic knowledge, and based on experience in the Bugis community, namely: (1) Environmental conservation can be guided by Sulapa Eppa as an environmental ethic based on Bugis cosmology; (2) Sangiang Serri as an eco-prophetic ritual that denounced heteropatriarchy; (3) Embodied resistance of Bissu’s gender identity ambivalence as a political representation of queer ecology.
Ekofeminisme Kritis: Menelaah Ulang Gender, Keadilan Ekologi, dan Krisis Iklim
Authors: Ayom Mratita Purbandani  , Mahaswa Rangga
Published: December 2022

Ecofeminism as an intellectual theory is often criticized for its incoherency in the body of thinking. Thus, ecofeminism is reputed as promising nothing transformative and adequate in answering the challenges of multiple ecological destructions, including climate crisis. However, the trajectories and influences of ecofeminism can’t be denied—from ethical debates to policies. Therefore, this research invites us to think about ecofeminism from a critical perspective without perpetuating patriarchal stereotypes and essentialism. The critical ecofeminism approach is an offer from writers to help to understand and portray gender-affected climate change impacts.
Perancangan Sistem Pengendalian Suhu Air Pada Shower Therapy Dengan Fuzzy Logic
Authors: Arianto Eko
Published: December 2022

Therapy is a form of health service to develop, maintain, and restore body movement and function by using manual handling and equipment. One of the therapies that many people need is for relaxation and reducing fatigue. One alternative is to use water as a medium (hydrotherapy). The pressure and temperature of the water used for shower therapy has been shown to provide physiological changes in humans. Shower therapy with warm water is strongly influenced by room temperature. The difference in outdoor air temperature (room) with the temperature of the water for bathing is very large will cause serious physiological problems. Therefore, to prevent the risk of differences in room temperature and water temperature being too large when bathing and/or shower therapy, a water temperature control system is needed that can maintain the temperature difference at a certain level. With a fuzzy logic controller system, the water temperature will be able to be controlled to adjust the outdoor air temperature (room). By adjusting the value of delta (∆) outside air temperature and water temperature, extreme temperature differences can be handled. The prototype of the water temperature control system in shower therapy with fuzzy logic has been successfully created with minimal functions with a water mixer system using solenoid valves. The water mixer can work at a minimum with the water temperature output which is still unstable and less accurate with a fairly high deviation. Setting the value of ΔT >5 produces a more stable water temperature output with an average deviation of <10%. The effect of pressure and water flow has not been seen and has not been observed.

La siembra de gramíneas en temporal árido se basa, principalmente, en propágulos con baja calidad en densidad específica y pureza física, resultando en bajo éxito. Se evaluaron, en condiciones de laboratorio, atributos físicos y fisiológicos en propágulos de Bouteloua curtipendula, Leptochloa dubia, Digitaria californica, Setaria macrostachya y Pennisetum ciliare (exótico naturalizado) como testigo. Se determinaron atributos físicos como tamaño y forma de cariópside, pureza física de cariópside, peso volumétrico, peso de mil semillas y atributos de calidad fisiológica como vigor, viabilidad y germinación en dos tipos de propágulos (cariópside y propágulos comercializados tradicionalmente) con dos fechas de cosecha. Se verificó el cumplimiento de los supuestos del análisis de varianza. Las variables no normales se transformaron y se analizaron con estadística no paramétrica Kruskall-Wallis y chi-cuadrada. Los datos se analizaron con un modelo de diseño completamente al azar y prueba de Tukey (P ≤ 0.05) para separación de medias. Se encontraron diferencias (P ≤ 0.001) entre especies, fechas de cosecha y tipo de propágulo para longitud de radícula y plúmula. La viabilidad total fue diferentes entre especies (P = 0.0046) y especies × fechas de cosecha para cariópside y propágulos tradicionales (P ≤ 0.0001). No se encontraron diferencias para plántulas anormales entre especies y fechas de cosecha en cariópsides (P > 0.05). Las dimensiones de cariópside fueron diferentes (P ≤ 0.0001) entre especies. A cuatro días de prueba, la germinación de cariópsides fue de 80 % en B. curtipendula. Respecto al propágulo comercial, L. dubia y P. ciliare alcanzaron germinación de 70 y 60 % al octavo día. Las especies de zonas áridas y semiáridas poseen amplio potencial de mejora de atributos físicos y fisiológicos de propágulo mediante beneficio y eliminación total o parcial de brácteas accesorias, lo cual es un factor importante para mejorar el establecimiento de praderas en temporal semiárido mediante la habilitación de siembra mecanizada resultante y otros beneficios de la semilla de calidad.

En el año 2020 la superficie cosechada de maíz en México fue de 7,156,391 hectáreas y la producción de 27,424,527 toneladas (SIAP, 2020), pero ésta no cubrió la demanda; por tanto, se realizaron importaciones de grano que superaron los 14 millones de toneladas, lo que ocasionó fuga de divisas, aumento en los costos de los productos derivados del maíz y dependencia alimentaria. La generación y uso de variedades mejoradas es una opción para aumentar el rendimiento de grano y la rentabilidad del cultivo, pues la semilla mejorada posee características genéticas que mejoran en las plantas la tolerancia a plagas, a enfermedades, al acame y a las pudriciones de la mazorca, lo que se traduce en mayor rendimiento de grano; además, se aumenta la calidad del grano, lo que facilita al productor comercializar su cosecha.

Araştırmanın çalışma grubunu amaçlı örnekleme yöntemlerinden ölçüt örnekleme yöntemiyle seçilmiş İç Anadolu Bölgesi’nde bulunan bir devlet üniversitesinde öğrenim gören fen bilgisi eğitimi, sınıf eğitimi ve sosyal bilgiler eğitimi anabilim dalı lisans programı 4. sınıf 90 öğretmen adayı oluşturmaktadır. Katılımcılar, amaçlı örnekleme yöntemleri arasında yer alan kriter örnekleme yöntemi kullanarak seçilmiştir. Araştırmada öğretmen adaylarının informal muhakemeleri önce nitel, sonrasında nitel bulguları nicel hale getirerek bütüncül olarak derinlemesine araştırıldığından keşfedici sıralı karma yöntem deseninden yararlanılmıştır. Nitel veriler içerik analizine tabi tutulmuştur. Nicel analiz yapılırken ise, değişkenler normal dağılım varsayımı karşılanmadığından ikili karşılaştırmalar için Mann-Whitney U-Testi, üç ya da daha fazla örneklem grubundan elde edilen verilerin karşılaştırılmasında için Kruskal-Wallis testi, çapraz tablo ve ki-kare testi kullanılmıştır. Araştırmadan elde edilen sonuçlara göre öğretmen adaylarının muhakeme sürecinde çok yönlü bakış açısına ve büyük bir çoğunluğunun kanıta dayalı muhakeme biçimine eğilimli olduklarına ulaşılmıştır. Verilen cevaplar incelendiğinde ise öğretmen adaylarında bilim-teknoloji ve ekoloji odaklı informal muhakeme biçimlerinin daha ağır bastığı bir durum ortaya çıkmıştır. Ancak katılımcıların %25’inden azı karşıt argümana karşı çürütücü argüman biçimi yapılandırabilmiştir. Ayrıca, bu çalışmada erkek ve kız öğrencilerin farklı amaçlarla (destekleyici argüman, karşıt argüman, çürütücü argüman) yapılandırdıkları argüman biçimlerinde önemli bir farklılık görülmemektedir. İnformal muhakeme seviyeleri bakımından ise öğretmen adaylarının yüksek bir muhakeme seviyesine sahip olduklarını söylemek mümkün değildir. Araştırmadan elde edilen bulgular ışığında önerilerde bulunulmuştur.

Desarrollo de aditivos antimicrobianos basados en nanopartículas metálicas obtenidas por síntesis verde para su aplicación en recubrimientos
Authors:   , Barberia Roque Leyanet
Published: December 2022

La preocupación creciente por el control de la colonización y crecimiento de hongos y bacterias en los interiores edilicios ha impulsado distintas líneas investigativas que comprenden el desarrollo de nuevas pinturas y recubrimientos con propiedades antimicrobianas que eviten el asentamiento de los microorganismos. Estas formulaciones contienen uno o más aditivos antimicrobianos llamados biocidas. Entre los productos investigados se destacan las nanopartículas de ciertos materiales metálicos (plata, cobre, selenio y oro) que han mostrado algún grado de bioactividad. Las nanopartículas se caracterizan por contar con propiedades dependientes del tamaño y la forma, a su vez, éstas son afectadas por el método y las condiciones de síntesis. Existe un creciente interés en desarrollar procesos de obtención de nanopartículas que sean amigables con el ambiente, es decir que eviten el uso de productos químicos cuestionados desde el punto de vista de su toxicidad. Esta tendencia enmarcada en la denominada química verde tiene como objetivos principales reducir los desechos, minimizar el uso de productos no seguros y beneficiar el uso de solventes y reactivos amigables con el ambiente. La síntesis verde de nanopartículas basada en el uso de extractos vegetales acuosos resulta promisoria por ser accesible, efectiva, segura, de bajo costo, no contaminante y por ofrecer vastas posibilidades. El objetivo de esta investigación fue desarrollar nuevos aditivos antimicrobianos de base nanotecnológica obtenidos por síntesis verde, aplicables en forma eficiente en la formulación de pinturas antimicrobianas que prevengan el biodeterioro. Para lograr este objetivo se trabajó en primer lugar en la obtención, caracterización y selección de las nanopartículas con mayor actividad tanto antibacteriana como antifúngica. En una siguiente etapa, se formularon y prepararon pinturas con los aditivos antimicrobianos desarrollados reemplazando los biocidas tradicionales que se usan en las pinturas comerciales fuertemente cuestionados desde el punto de vista de la salud y el impacto ambiental.
La vinculación entre la COVID19 y los Modelos de Gobernancia Corporativa
Authors:   , Pizzorno Vicente Constantino
Published: December 2022

Se evaluó la respuesta de tres modelos de gobernancia corporativa a un cambio exógeno y disruptivo como la COVID19. Se realizó un estudio de eventos basado en retornos anormales de las acciones de veinticuatro empresas de seis países. Se emplearon dos técnicas: el modelo de mercado base CAPM y el modelo de Tres Factores de Fama & French. Se compararon rendimientos anormales pre y post hito obtenidos con ambos modelos. Esta comparación sugiere que el modelo Latino es el que presenta el menor impacto negativo. No se midió la precisión estadística de este resultado. En el análisis de regresión, no se corroboró que las variables correspondientes a los modelos de gobernancia tuvieran una vinculación estadísticamente significativa con los retornos anormales estudiados, aunque en la mayoría de los escenarios el resultado es estadísticamente significativo. Si bien existe cierta evidencia preliminar que sugiere una respuesta diferencial por parte de cada uno de los tres modelos de gobernancia analizados frente a la COVID19, para los niveles usuales de significancia se puede afirmar que los análisis de regresión realizados no permiten descartar la Hipótesis nula planteada. Por lo tanto, con los resultados obtenidos, no es posible corroborar la Hipótesis principal.

Seismic monitoring in the region was produced by a seismic network of 58 stations in 2016 and 60 stations in 2017. All stations were digitally equipped. The seismic network provided representative registration of earthquakes with KR≥7.0 in most of the region, in the central (including the Greater Sochi region) and eastern parts of the region – with KR≥6.0, and in some local zones with KR≥5.5. In general, 5594 earthquakes have been recorded in the region and its environs. 66 earthquakes were felt in the Caucasus settlements, 24 of them occurred in the North Caucasus region. The maximum shaking intensity, Imax=6 by the MSK-64 scale, was noted at the March 6, 2017 earthquake with KR=10.9 occurred in the territory of the Chechen Republic. August 7, 2016 earthquake in the Azov Sea, not far from Mariupol, was felt up to I=5. The strongest and most perceptible earthquakes were registered in Dagestan (in the tectonic regions of the Greater Caucasus and the Dagestan wedge). In accordance with the seismicity level scale "SOUS-09", seismicity of the North Caucasus in 2016–2017 is set as a "background average" for the observation period from 1962 to 2017.

In 2016–2017, seismic monitoring in the Kopetdag region was carried out by a network of 34 seismic stations of the Institute of Seismology and Atmospheric Physics of the Academy of Sciences of Turkmenistan. This network included 20 stationary and 14 mobile stations. Within just 2 years, 651 earthquakes with KR≥8.6 have been registered, of which 41 were tangible. Focal mechanisms were determined for 83 seismic events. In Turkmenistan, the strongest and most felt earthquakes occurred in the Balkhan-Caspian region: on October 26, 2016 with KR=12.9 (Mw=5.5) and on February 5, 2017 with KR=12.4 (Mw=5.0). The first event was felt in Balkanabat city with intensity of 4–5, the second – in Kumdag settlement with intensity of 4. Among the earthquakes outside of Turkmenistan, the events of the Turkmen-Khorasan area stand out with the highest magnitude and shaking intensity: April 5, 2017 with KR=14.3, Mw=6.0 and May 13, 2017 with KR=13.4, Mw=5.7. The first event was felt with intensity of I=6 in the Iranian city of Torbet Jam and with I=5 in several settlements. Among the seismoactive areas of the Kopetdag region, the largest amount of seismic energy in 2016 was released on the territory of the Balkhan-Caspian area, in 2017 – in the Turkmen-Khorasan area.
