This study aimed to assess the morphological and physio-biochemical responses of a commercial watermelon (Citrullus lanatus (Thunb.) Matsum. and Nakai) cv. ‘Crimson Sweet’ grafted onto a drought-tolerant rootstock of wild watermelon (bitter apple, Citrullus colocynthis (L.) Schrad, ‘Esfahan’) in comparison with an ungrafted ‘Crimson Sweet’ watermelon or one grafted onto a commercial interspecific Cucurbita hybrid (Cucurbita maxima Duch. × Cucurbita moschata Duch.) rootstock (‘Shintoza’) under water stress. The experiment was conducted in pots under a controlled environment in a greenhouse, and water stress was imposed by maintaining moisture level in pots at 100% (well water (WW)) or 50% (water deficit (WD)) of container capacity (CC). WD significantly decreased most of the morphological traits in ungrafted and grafted plants, while the decrease in growth traits was lower in grafted plants than ungrafted plants. The response of grafted plants onto wild watermelon rootstock (‘Esfahan’) for most of the affected parameters (shoot fresh and dry weight, vine length and internodal length) was, however, comparable to those grafted onto commercial Cucurbita hybrid rootstock (‘Shintoza’). Plants grafted onto bitter apple (wild watermelon) exhibited a relatively lower decrease in growth and biomass, besides showing higher antioxidant activity (e.g., guaiacol peroxidase) concomitant with the lower accumulation of malondialdehyde and electrolyte leakage in the leaf tissues in comparison with ungrafted plants. The overall growth performance, as well as those under water stress conditions in commercial rootstock-grafted watermelon, was related to its better plant water status (e.g., high relative water content) which was likely ascertained by its greater root efficiency. This suggests that watermelons grafted onto bitter apple rootstock and Cucurbita hybrid rootstock were constitutively more resistant to drought, with higher efficiency in mitigating oxidative stress than ungrafted treatment. The above findings demonstrated that bitter apple, a well-adapted desert species, can be used as an alternative rootstock to commercial rootstocks (e.g., ‘Shintoza’) for watermelon grafting under water stress conditions. In addition, bitter apple rootstock can be involved in rootstock breeding programs to improve drought tolerance in watermelon.

Authors: Lippert Julia F. , Furnari Mackenzie B. , Kriebel Charlie W.
Published: October 2021

The economic downturn due to the COVID-19 pandemic disproportionately impacted the food service industry—one of the largest workforce sectors in the United States. The purpose of this qualitative study was to explore the occupational stressors experienced by restaurant and food service workers during the COVID-19 pandemic through a detailed assessment of their lived experiences. Thematic analysis was used to identify patterns within data from sixteen semi-structured interviews with people employed or recently employed in the restaurant industry during July of 2020. Five themes were highlighted including fear of being exposed to the COVID-19 virus while working under inadequate safety policies, job insecurity, inconsistent pay and hours and a lack of health benefits and paid time off, all of which increased occupational stress and led to uncertainty if respondents would return to the restaurant industry. Hardships associated with the pandemic were mitigated by the support and connections fostered by the communities built within the restaurants. Results led to several recommendations to address the social and economic contributors to occupational stress at the structural and population levels which can be used in the current and post-pandemic workplace.

Published: October 2021

Estimation of health-related physical fitness (HRPF) levels of individuals is indispensable for providing personalized training programs in smart fitness services. In this study, we propose an artificial neural network (ANN)-based estimation model to predict HRPF levels of the general public using simple affordable physical information. The model is designed to use seven inputs of personal physical information, including age, gender, height, weight, percent body fat, waist circumference, and body mass index (BMI), to estimate levels of muscle strength, flexibility, maximum rate of oxygen consumption (VO2max), and muscular endurance. HRPF data (197,719 sets) gathered from the National Fitness Award dataset are used for training (70%) and validation (30%) of the model. In-depth analysis of the model’s estimation accuracy is conducted to derive optimal estimation accuracy. This included input/output correlation, hidden layer structures, data standardization, and outlier removals. The performance of the model is evaluated by comparing the estimation accuracy with that of a multiple linear regression (MLR) model. The results demonstrate that the proposed model achieved up to 10.06% and 30.53% improvement in terms of R2 and SEE, respectively, compared to the MLR model and provides reliable estimation of HRPF levels acceptable to smart fitness applications.

Authors: Rohlman Diane S. , TePoel Megan , Campo Shelly
Published: October 2021

Adolescents and young adults (<25 years) working in agriculture are at greater risk of injury than youth working in other industries. Supervisors play an important role in protecting these young workers who lack workplace experience and whose bodies and brains are still developing. A theoretically based approach was used to develop an online training for supervisors of young agricultural workers. The training addresses an expanded view of occupational safety that not only addresses injury prevention, but also focuses on health promotion and worker well-being using a Total Worker Health approach. A pre-post/post study design was used to evaluate the training. Questionnaires included demographics, workplace characteristics, knowledge, beliefs about protecting young workers, and supervisors’ communication behaviors. One-hundred-eighty-two participants completed all parts of the efficacy trial. A post-test administered immediately after completing the training, indicated that supervisors had greater understanding of the risks to young workers and at 3-month follow-up were more likely to engage in communication behaviors to protect the safety and health of young workers. Positive changes in when, how, and under what circumstances supervisors talk about safety and health occurred. Establishing patterns of protective behaviors in the workplace can have lifelong impact, particularly among young workers.

Published: October 2021

This study aims to establish a link between disturbances in the night sleep habitus, quality of sleep, and daytime sleepiness in adolescents with Internet addiction and different types of content consumed. Methods: This is a cross-sectional observational study of a school sample in three large cities in Central Siberia. 4615 schoolchildren of 12–18 years old were examined. The Russian-language versions of the Chen Internet Addiction Scale, the Game Addiction Scale for Adolescents, and the Social Media Disorder Scale were used to identify Internet addiction. Questions from the Pittsburgh Sleep Quality Index questionnaire were used to assess nighttime sleep. Daytime sleepiness was assessed using the Pediatric Daytime Sleepiness Scale questionnaire. Results: Adolescents with Internet addiction go to bed and wake up late; they are characterized by a decrease in the duration of nighttime sleep, an increase in sleep onset latency, and frequent nighttime awakenings, as well as more pronounced daytime sleepiness. Among the sleep parameters studied, the indicators of daytime sleepiness and night awakening scales have the highest effect size in Internet-addicted adolescents, regardless of the media consumed. Conclusion: Internet-addicted adolescents are characterized by significant disturbances in the quality of nighttime sleep and excessive daytime sleepiness, which requires appropriate psychological correction.
A Study on the Installation of Facilities for People with Disabilities in Dental Institutions of Chungbuk, South Korea
Authors: Kim Sun-ju , Park Jin-sun
Published: October 2021

To maintain the oral health and ability to smoothly receive dental treatment of people with disabilities, their accessibility to dental institutions must be enforced. Hence, this study aimed to assess the status of installation of convenience facilities for people with disabilities in dental institutions in Chungbuk Province, South Korea. According to the checklist based on installation items for convenience facilities for people with disabilities, 245 dental institutions in Chungbuk Province were visited and investigated to examine whether they had installed internal, intermediary, sanitary, and information-related facilities for people with disabilities. Inputs were analyzed using SPSS 25.0 (IBM, Armonk, NY, USA). Frequency analysis by item was conducted to determine the rate of installation, and Fisher’s exact test was performed to analyze the actual state of installation according to the type of institution. The results revealed a relatively higher rate of appropriate installation and access routes to the main entrance and parking spaces for people with disabilities in terms of intermediary and internal facilities, but at times they were installed at inappropriate locations or lacked proper signboards. The state of installation of convenience facilities by institution type was 0–1.3% per item at the clinic level but 75–87.5% per item in general and dental hospitals (p < 0.001). Insufficient government management and supervision at clinic-level dental institutions lead to limited scope for regulating the installation of convenience facilities. Better laws, with continued support and supervision of central and local governments, are needed to resolve this issue.

Published: October 2021

Pesticides play a very important role for ensuring food security and economic growth but their use can cause harmful effects to human health and to the environment. The study aimed to investigate the level of knowledge, health risk perceptions, and experiences on the practice of pesticide use and management among extension officers in Ethiopia and plant doctors in Hungary. A questionnaire survey among 326 officers was conducted in the two study areas and data were analyzed by ordinal logistic regression. According to the findings, Hungarian officers had much better knowledge of pesticide products (92%), and less frequently experienced pesticide poisoning among applicators (7%) than the Ethiopians (66% and 41%, respectively). Hungarian officers perceived less health risk of pesticide use (AOR = 0.46, 95%, Cl: 0.27–0.80), were ten times more likely to deem the pesticide management system effective (AOR = 10.23, 95%, Cl: 5.68–18.46) and were nine times more likely to report that applicators used personal protective equipment (AOR = 8.95, 95%, Cl: 4.94–16.28). A significant proportion of officers from both countries reported inappropriate methods of pesticide residue disposal. These observations point out that the situation of pesticide use and knowledge and management of pesticide products is definitely better in Hungary; nevertheless, the issue continues to need more attention in both settings.

Published: October 2021

Background: The COVID-19 pandemic led to a change in work organization with the development of telework. The purpose of this study was to assess the prevalence of anxiety and depressive symptoms in teleworking staff in a university hospital center in France during the first lockdown, and to identify personal, medical and occupational factors associated with anxiety disorder. Methods: A cross-sectional observational study was conducted in 474 hospital staff working from home during the first lockdown. The sociodemographic, occupational and medical information (anxiety and depressive disorders measured on the Hospital Anxiety and Depression (HAD) scale) was collected by an anonymous online self-administered questionnaire. The variables associated with anxiety disorder were investigated by a univariate analysis (chi² and Fisher tests) and a multivariate analysis (logistic regression model). Results: Three hundred and forty hospital staff participated in the study (72% response rate). Of the participants, 106 subjects (32.1%) showed signs of an anxiety disorder and 26 (7.65%) of a depressive disorder. An anxiety disorder was significantly associated with mental workload, changes in working hours, difficulties in teleworking due to issues of internet connection or due to noise, difficulties in combining family and occupational life, sleep disturbance, worry about media information and worry about the health of a loved one. An anxiety disorder remained associated with occupational stress and personal stress during lockdown after a multivariate logistic regression. Conclusions: This study highlighted the association between an anxiety disorder and perceived occupational and personal stress levels in hospital staff teleworking during the first lockdown. Stress management workshops could be proposed to hospital staff. Prevention of anxiety requires reinforced medical monitoring and reduced stress.

Published: October 2021

This study investigated the effects of kinesio taping (KT) or KT plus conventional therapy on pain, muscle strength, funrefction, and range of motion in patients with knee osteoarthritis (OA). Data sources: Databases included PubMed, Ovid Medline, CINAHL, Airiti Library, EMBASE, and WOS search engines. Search terms related to KT and knee OA were combined and searched. Articles that met the inclusion criteria and were graded with a Jadad score ≥3 were included in a meta-analysis to calculate the total effect. The exclusion criteria were non-English-language articles, non-original articles, non-full-text articles, no description of the intervention, or articles with a Jadad score ≤2. Eleven articles were included in the meta-analysis. KT treatment had a significant small total effect on pain reduction (p < 0.001; n = 1509; standardized mean difference (SMD) = −0.42; 95% CI = −0.65 to −0.18) and a significant moderate total effect on isokinetic muscle strength improvement (p = 0.001; n = 447; SMD = 0.72; 95% CI = 0.28 to 1.16). No significant total effects of KT on isometric muscle strength, time to complete functional tasks, or ROM improvement were found. KT or KT plus conventional therapy has a significant effect on pain relief and isokinetic but not isometric muscle strength improvement in patients with knee OA. KT can be an effective tool for treating knee OA pain and is especially valuable for aiding in isokinetic muscle strength. (PROSPERO register ID: CRD42021252313)

Published: October 2021

Hospital readmissions pose a threat to the constrained health resources, especially in resource-poor low-and middle-income countries. In such scenarios, appropriate technologies to reduce avoidable readmissions in hospitals require innovative interventions. mHealth and teach-back communication are robust interventions, utilized for the reduction in preventable hospital readmissions. This review was conducted to highlight the effectiveness of mHealth and teach-back communication in hospital readmission reduction with a view to provide the best available evidence on such interventions. Two authors independently searched for appropriate MeSH terms in three databases (PubMed, Wiley, and Google Scholar). After screening the titles and abstracts, shortlisted manuscripts were subjected to quality assessment and analysis. Two authors checked the manuscripts for quality assessment and assigned scores utilizing the QualSyst tool. The average of the scores assigned by the reviewers was calculated to assign a summary quality score (SQS) to each study. Higher scores showed methodological vigor and robustness. Search strategies retrieved a total of 1932 articles after the removal of duplicates. After screening titles and abstracts, 54 articles were shortlisted. The complete reading resulted in the selection of 17 papers published between 2002 and 2019. Most of the studies were interventional and all the studies focused on hospital readmission reduction as the primary or secondary outcome. mHealth and teach-back communication were the two most common interventions that catered for the hospital readmissions. Among mHealth studies (11 out of 17), seven studies showed a significant reduction in hospital readmissions while four did not exhibit any significant reduction. Among the teach-back communication group (6 out of 17), the majority of the studies (5 out of 6) showed a significant reduction in hospital readmissions while one publication did not elicit a significant hospital readmission reduction. mHealth and teach-back communication methods showed positive effects on hospital readmission reduction. These interventions can be utilized in resource-constrained settings, especially low- and middle-income countries, to reduce preventable readmissions.

Published: October 2021

In order to achieve the United Nations 2030 Sustainable Development Goals (SDGs) related to green spaces, monitoring dynamic urban green spaces (UGSs) in cities around the world is crucial. Continuous dynamic UGS mapping is challenged by large computation, time consumption, and energy consumption requirements. Therefore, a fast and automated workflow is needed to produce a high-precision UGS map. In this study, we proposed an automatic workflow to produce up-to-date UGS maps using Otsu’s algorithm, a Random Forest (RF) classifier, and the migrating training samples method in the Google Earth Engine (GEE) platform. We took the central urban area of Beijing, China, as the study area to validate this method, and we rapidly obtained an annual UGS map of the central urban area of Beijing from 2016 to 2020. The accuracy assessment results showed that the average overall accuracy (OA) and kappa coefficient (KC) were 96.47% and 94.25%, respectively. Additionally, we used six indicators to measure quality and temporal changes in the UGS spatial distribution between 2016 and 2020. In particular, we evaluated the quality of UGS using the urban greenness index (UGI) and Shannon’s diversity index (SHDI) at the pixel level. The experimental results indicate the following: (1) The UGSs in the center of Beijing increased by 48.62 km2 from 2016 to 2020, and the increase was mainly focused in Chaoyang, Fengtai, and Shijingshan Districts. (2) The average proportion of relatively high and above levels (UGI > 0.5) in six districts increased by 2.71% in the study area from 2016 to 2020, and this proportion peaked at 36.04% in 2018. However, our result revealed that the increase was non-linear during this assessment period. (3) Although there was no significant increase or decrease in SHDI values in the study area, the distribution of the SHDI displayed a noticeable fluctuation in the northwest, southwest, and northeast regions of the study area between 2016 and 2020. Furthermore, we discussed and analyzed the influence of population on the spatial distribution of UGSs. We found that three of the five cold spots were located in the east and southeast of Haidian District. Therefore, the proposed workflow could provide rapid mapping and dynamic evaluation of the quality of UGS.

Authors: La Guardia Marcello , D’Ippolito Filippo , Cellura Maurizio
Published: October 2021

The recent diffusion of RES (Renewable Energy Sources), considering the electric energy produced by photovoltaic and wind plants, brought to light the problem of the unpredictable nature of wind and solar energy. P2G (Power to Gas) implementation seems to be the right solution, transforming curtailed energy in hydrogen. The choice of the settlement of P2G plants is linked to many factors like the distances between the gas grid and the settlement of RES plants, the transportation networks, the energy production, and population distribution. In light of this, the implementation of a Multi-Criteria Analysis (MCA) into a Geographic Information System (GIS) processing represents a good strategy to achieve the goal in a specific territorial asset. In this work, this method has been applied to the case of study of Sicily (Italy). The paper shows in detail the geomatic semi-automated processing that allows to find the set of possible solutions and further to choose the best localization for new P2G plants, connected to a Relational Database Management System (RDBMS) and integrated with a WebGIS visualization for real-time analysis. This system is useful for the management, the development, and the study of hydrogen technologies, in order to link the electrical network and the gas network datasets with economical and infrastructural assets through GIS processing. In the future new factors will join in the process as policies on hydrogen take shape.
EVALUACIÓN DEL ACEITE ESENCIAL Y ESTUDIO DE CONSERVACIÓN EN FRIO DEL Cymbopogon Citratus CULTIVADO EN LA REGIÓN DEL QUINDÍO

Published: October 2021

El continuo e implacable vertido de aguas residuales generados por la mayoría de los usos del agua en  cuencas hidrográficas conlleva a la degradación de los ríos en muchas cuencas en el mundo. A pesar de los esfuerzos gubernamentales y no gubernamentales por la descontaminación de las aguas residuales en las cuencas hidrográficas,  estos no han sido coordinados dentro de una valoración integral de acuerdo a las condiciones en muchas de estas. 

El presente artículo se refiere a las perspectivas, desafíos e instrumentos de gestión para alcanzar Objetivos de Calidad del Agua (OCA) en cuencas hidrográficas. Se presenta un análisis y reflexión sobre la panorámica internacional, nacional y regional. Se plantean desafíos a que se enfrentan las autoridades ambientales para alcanzar dichos objetivos, tales como: variabilidad espacio-temporal de la contaminación, discontinuidad y/o confiabilidad de la información, y aspectos socioeconómicos. Se describen algunos OCA en una cuenca española, según la Directiva Marco Europea del Agua (DMA) y otra colombiana. Se proponen instrumentos económicos, jurídicos y herramientas de apoyo a la decisión para que las autoridades ambientales aborden la problemática desde una Gestión Integral de Recursos Hídricos (GIRH), de cara a alcanzar los OCA fijados en dichas cuencas.

Published: October 2021

The authors investigate the economic and institutional foundations of the functioning of state corporations. The study revealed the problem of diffusion of innovations from the military sectors to the civilian sectors, which significantly reduces the competitiveness of the latter. The experience of foreign countries, especially the United States, shows that dual technologies, the diffusion of innovations from the military sector into the civilian sector, can give an impetus to the development of civilian industries with obtaining high-quality, unique, competitive products on the world market. It is important to note that state corporations have the potential for the development of dual technologies, but the problem of coordinating the activities of controlled enterprises significantly reduces the possibilities for diversifying production.

Нитридные полупроводники III группы, такие как InN, GaN и AlN, в последние десятилетия
представляют огромный интерес для исследования. Это обуславливается возможностью создания
фотоприемных и светоизлучающих устройств от инфракрасного до ультрафиолетового диапазона
используя твердые растворы III-нитридов [1]. Проблемой при создании таких устройств является
высокая плотность дислокаций в выращенных структурах, которые являются центрами
безызлучательной рекомбинации и снижают эффективность работы оптоэлектронных устройств.
Возможный подход к преодолению этой проблемы заключается в использовании трехмерных

Существующая тенденция роста несущих частот оптических линий связи (длина волны 1,5 мкм) до
сотен ГГц [1] требует развития миллиметровых (субтерагерцовых) технологий. В частности, идет
поиск материалов, обеспечивающих эффективное взаимодействие оптического и ИК излучения с
миллиметровыми волнами (100–300 ГГц). Поскольку существует проблема ограниченного
быстродействия устройств «классической» электроники на обозначенных частотах, пропагандируется
оптико-оптическое преобразование лазерного излучения в миллиметровый диапазон и обратно, т.е.
минуя устройства классической электроники. Такое преобразование может быть основано на
принципах нелинейной кристаллооптики.

Подложки InP(001) используют для создания гетероэпитаксиальных структур (ГЭС), на основе
которых изготавливают транзисторы с высокой подвижностью электронов, лазеры, электрооптические
модуляторы и фотодиоды [1]. Рост гетероструктуры начинается с удаления аморфного окисного слоя
подложки. Обычно окисный слой на подложке InP удаляют высокотемпературным отжигом в потоке
As. Однако в процессе отжига происходит изменение элементного состава поверхности подложки с
образование твердого раствора InPAs и островков InAs [2, 3]. Решеточное рассогласование между InP
и InAs приводит к возникновению напряжений и центрам зарождения дефектов в ГЭС [4], что влечет
изменения в начальных этапах зародышеобразования и последующих процессах эпитаксиального
роста. Поэтому целью работы является исследование процесса формирования InAs островков на
поверхности InP(001) в процессе высокотемпературного отжига в потоке мышьяка.

Published: October 2021

Dört temel unsurdan biri olması ve hayati önem taşıması nedeniyle su, divan şiirinde çeşitli yönleriyle sıklıkla ele alınmıştır. Suyla birlikte, kelimenin eş anlamlıları durumundaki Farsça “âb”, Arapça “mâ’” ve “zülâl” de divan şiirinde kullanılmıştır. Su ve suyla ilgili unsurlar divan şairinin hayal dünyası içinde çeşitli benzetmelere konu olmuştur. Benzetme ve hayallerin yanı sıra divan şairleri, şiirlerinde su ile ilgili atasözlerine ve deyimlere, telmih unsurlarına, bazı inanç ve âdetlere yer vermişlerdir. Su dağıtmak, Kâbe’ye su götürmek, çeşme ve sebil yaptırmak vb. hayır işleri ya da suyu ilgilendiren çeşitli imar faaliyetleri sebebiyle yazılan, tarih düşülen şiirlerde sudan söz edilmiştir. Şüphesiz suyla ilgili unsurların diğer örneklere göre daha yoğun yer aldığı şiirler “su” redifli şiirlerdir. Söz konusu şiirler farklı nazım şekilleriyle yazılabileceği gibi redifleri de kimi zaman “su”, kimi zaman eşanlamlılarından biri olabilmektedir. Makalemizde, divan şiirinde su ve suyla ilgili bazı unsurların kullanım özelliklerine değindikten sonra XV. yüzyıl divan şairi Necâtî’nin “âb (su)” redifli kasidesini biçim, içerik, dil ve anlatım bakımından inceleyeceğiz.

Technology consideration in tennis umpiring: replacing the humans
Authors: Carboch Jan
Published: October 2021

New technologies step into sports refereeing, officiating, or umpiring. This technology can assist humans to avoid blunders or errors. However, in tennis, this technology now starts to replace humans, i.e. the line umpires. In this letter, we try to provide insight into potential problems, that this technology brings, but also we try to provide its benefits. We offer considerations from the umpire (human) view.  It is not very clear and we consider it still in a grey zone, what are the next best steps, even though it seems that the new technology implementation is unavoidable. In this letter, we focus on tennis line umpires, because technology is replacing them now. Therefore, would like to encourage and call for more research on this currently hot topic.

Durante la pandemia de COVID-19, existen muchos desafíos, a nivel nacional y mundial, incluidos el empleo, la movilidad, los deportes y la educación, siendo necesario prevenir la propagación del virus. Por lo tanto, muchos niños difícilmente pueden seguir estudiando y practicando debido a la falta de Internet o dispositivos electrónicos que aseguren el desarrollo de contenidos en cada nivel escolar. También con esta situación perdieron el interés. Por tal razón también afectó en el ámbito de la educación física, por ello en el estudio realizado y los resultados obtenidos los padres de familia consideran de gran importancia motivarlos a aprender todo lo que la escolarización aporta a su formación. Es decir que la motivación es probablemente el eje principal del plan de aprendizaje, por lo que siempre debe estar presente en cada momento de la clase.

Published: October 2021

La investigación se plantea analizar la incidencia de la fijación de la caución al conceder el recurso de casación en materia precautelar; básicamente el principio constitucional de seguridad jurídica, y generar confianza de la administración de justicia. Desde el paradigma cuantitativo, es una investigación con una metodología de tipo descriptiva documental con un diseño bibliográfico, reconociendo la búsqueda documental en fuentes bibliográficas, jurídicas, investigaciones previas, leyes y normas. Se aplicó un cuestionario a 15 abogados en libre ejercicio de la Ciudad de Portoviejo. Se concluye, que si bien es cierto los abogados tienen un conocimiento básico de los recursos extraordinarios del ordenamiento jurídico ecuatoriano, muy pocos de ellos han interpuesto un recurso de casación, esto debido principalmente a que no están capacitados y ni formados para realizar este recurso.
Acción de protección y su indebida aplicación en los procesos constitucionales ecuatorianos
Authors: Mendoza-Cedeño Ronald Argenis , Arrias-Añez Julio César-de-Jesús , Rivera-Velasco Luis Antonio
Published: October 2021

El objetivo general de la investigación fue realizar un análisis jurídico sobre la acción de protección como garantía constitucional y su incorrecta aplicación en los procesos legislativos ecuatorianos. Desde una perspectiva cuantitativa y a través de una exploración bibliográfica-documental, con el fin de obtener mayor información mediante la revisión de documentos, datos de investigaciones, textos, leyes, y normas. Con el apoyo del método analítico-sintético facilitó el análisis minucioso del problema de estudio. El ordenamiento jurídico ecuatoriano tiene un carácter garantista, por lo que los poderes y funciones del Estado deben acatar y cumplir fielmente sus preceptos. Como conclusión se manifiesta que la acción de protección es capaz de tutelar y descubrir real el goce de los derechos reglamentarios, ya que aun en un Estado con un ordenamiento jurídico casi perfecto, seguirá existiendo siempre una desconexión entre normatividad constitucional y facticidad, dando pie a un margen estrecho pero irreductible de ilegitimidad.

VIBRATONAL MECHANICS AND STOCHASTIC QUASI-RESONANCES
Authors: Kremer Eugen
Published: October 2021

The concept of vibrational mechanics was pioneered in the works by Professor I.I. Blekhman and developed by his numerous disciples and coleagues. It is a powerful tool for the study of such systems with fast excitations, in which slow motion is of primary interest. One important application of this approach is the stochastic resonance, the phenomenon of resonance-like response of slow variables to intensity of stochastic excitation. This phenomenon is considered within the framework of vibrational mechanics as forced lowfrequency oscillations near the natural frequency, which evolves under the influence of changing high-frequency stochastic excitation. We propose a generalization of this approach to the case when the evolution of low-frequency properties of the system leads not to the equality of the natural
frequency and the frequency of the external slow force, but to the loss of stability in a certain interval of the stochastic excitation intensity. Since in this case, as for stochastic resonance, the external manifestation of the process is the resonance-like
response of the system, the considered effect can be called stochastic quasi-resonance, As an example, we consider a rotor with anisotropy of bending stiffness under the action of stochastic angular velocity oscillations.
