Empowering leadership and employee constructive deviance: Role breadth self‐efficacy as a mediator
Authors: Liu Xinyi , Liu Chunzhao , Li Jianchun
Published: April 2024

Although researchers have demonstrated the significance of leadership style in facilitating employee constructive deviance, there is still limited understanding of the precise process via which an empowering leadership style contributes to the promotion of constructive deviance. Based
on social cognitive theory, we constructed a model to explain why empowering leadership can increase employees’ constructive deviance, and tested it with data obtained from 217 supervisor–subordinate dyads in South Chinese enterprises. An examination using structural equation modeling
revealed direct and indirect positive associations between empowering leadership and constructive deviance, mediated by role breadth self‐efficacy. The findings of this study establish a theoretical framework and offer practical recommendations for leaders seeking to implement effective
empowerment tactics aimed at motivating staff to engage in constructive deviance.
The impact of virtual or blended learning on sense of belonging in first-year undergraduate health sciences students enrolled in an inquiry-based course
Authors: Wong Michael , Al-saqqar Shahad , Nash Jennifer , Al-Humuzi Ali , Dottori Mark , Secord Margaret
Published: April 2024

Literature suggests post-secondary students felt disengaged and socially isolated while learning virtually, especially during the COVID-19 pandemic. Here we explored whether a sense of belonging is differentially achieved in an inquiry-based course between two different delivery formats: virtual and blended (combination of virtual and in-person). Our primary measurement instrument was a modified version of the 26-item Sense of Belonging-Revised Scale, which we distributed to all first-year health sciences students enrolled in an Inquiry course at [institution name removed for blinding purposes] University during the 2021-2022 school year. Data analyses revealed no statistically significant difference between the two groups across the four subscales of the Sense of Belonging-Revised Scale: perceived peer support, perceived classroom comfort, perceived isolation, and perceived faculty support. As promoting community is a core skill in our Inquiry course, this may have reduced the perceived difference between the two groups.  Future directions include exploring facilitators’ perceptions and experiences across course delivery formats.

Designing a Resilient Building Maintenance Program: Integrating Preventive and Predictive Maintenance at the U.S. Navy
Authors: Pluméy Nathan , Kim Amy
Published: April 2024

Building equipment failure can have drastic effects on a company's operations and budget. This paper presents two types of maintenance approaches that if done effectively, can prevent or significantly reduce the failure of building equipment assets. The first is traditional time-based preventive maintenance (PM), which conducts prefailure inspections and tasks in a cyclic time-based approach. The second, is predictive maintenance (PdM), which conducts maintenance functions based on the condition of the equipment found through continuous or cyclic measurements and analysis during machine operation.

The purpose of investigating these maintenance approaches is to determine whether we can improve on the U.S. Navy's (Navy) existing facility maintenance program, helping to reduce overall costs while improving sustainability, equipment resiliency, and efficiency. By presenting each maintenance program and leveraging today's technologies we show that these advancements in technology can directly improve the Navy's operational mission and warfighter readiness.

Research was conducted through the following methods: interviews, books, third party reports, journal articles, industry websites and articles that focus on equipment maintenance. The Navy, the National Aeronautics and Space Administration (NASA), and the University of Washington provided case studies, existing facility/utility maintenance data, and budget information used in this research. The results show that PdM approaches using advanced analytics are more effective in diagnosing equipment, prescribing equipment problems, and predicting equipment failure. It will also show that when a PdM model is used, building tenants have less operational impacts as equipment operates longer with less downtime between maintenance events. By changing to a PdM program, facility managers and owners can improve asset efficiency and resilience, directly improving environmental sustainability and lowering overall longterm costs. It highlights the significant capital costs of a fully online PdM program and the benefits of using a hybrid model of PM and PdM.

This research concludes with an overview of how building maintenance is currently being conducted on Navy bases by Naval Facilities Engineering Systems Command (NAVFAC), and how they are transitioning to a more sustainable maintenance program leveraging existing advanced metering infrastructure (AMI), building control systems (BCS), and utility control systems (UCS) with Smart Grid (SG), OSI Pi, and advanced analytics. In addition, major gaps in this transition are identified, and solutions are proposed to optimize these building system investments.
Factors Influencing Energy-Efficiency Retrofits in Commercial and Institutional Buildings: A Systematic Literature Review
Authors: Kim Amy A. , Medal Lysandra
Published: April 2024

Renovating existing buildings to render them more energy efficient is critical. However, current energy-efficiency efforts in the building sector remain insufficient. Despite the growing literature related to energy efficiency in buildings, context-driven reasons for stakeholders to undertake energy-efficiency retrofits remain less understood. The researchers conducted a systematic literature review to synthesize and consolidate the results of studies worldwide from 2009 to 2020, examining factors and associated contexts that influence building stakeholders’ decisions to implement energy-efficiency retrofits. The review involved searching databases and topic-specific journals using multiple keywords and synonyms for energy-efficiency retrofits and decision-making. The initial search yielded 25,093 articles, and 134 were further assessed for inclusion and exclusion. Forty-two of those articles met the criteria for inclusion and were examined to evaluate the factors and context associated with the decisions related to energy-efficiency retrofits. Recent relevant research was analyzed, considering methodologies, regions, economic development, building types, participant characteristics, and study size. Based on the extensive review of the literature, this study identified 30 factors that can be categorized under seven decision criteria involved in determining retrofits: economic feasibility, team process, technical practicality, institutional characteristic, governmental policy, occupant impact, and environmental impact. The main factors that influenced energy retrofit decisions included life cycle cost, coordination and collaboration, system compatibility, internal value, government commitment, satisfaction and well-being, and eco-friendly installation. Variations regarding factors influencing stakeholders’ perceptions among different regions and building types were also examined. The study found that risk management, technology readiness, and standards and regulations were more significant in countries with developing economies. Conversely, system compatibility, reputation, and political influence were more important in developed economies. The findings from this study provide insights into future research that may guide the development of more context-appropriate strategies that drive stakeholders to implement energy-efficiency retrofits in their buildings.
Senior Management Succession Challenges for U.S. Healthcare Facility Operations
Authors: Call Steven , Smithwick Jake
Published: April 2024

Purpose

The purpose of this research was to better understand current state of mid- and senior-level healthcare facility managers to explore potential roadblocks to FM succession related to demographics, backgrounds, and perceptions in supporting future research prioritization for healthcare facility executive leadership development.

Methodology

A survey was designed to collect information on facility managers’ gender, race, age, job level, employer industry, retirement timeframe, educational attainment, and perceptions of their employers’ recruiting and succession planning. The survey was sent electronically in February 2021 to more than 12,400 FM professionals with a 29% response rate. Only information from U.S. respondents working in healthcare facility operations was used in this study.

Findings

The healthcare industry is struggling to attract and retain senior-level facility managers. The difficulty in finding qualified facility managers to fill senior-level positions does not appear to be related to a lack of interested candidates or pay. Factors impeding recurring facility workforce development and succession to senior healthcare FM roles may be related to low succession planning adoption by healthcare organizations, an aged facility workforce, and limited undergraduate education achievement from traditional candidates.

Originality

Healthcare organizations may prioritize these factors in addressing ongoing FM workforce attrition and development challenges to ensure a sustainable pipeline of qualified facility managers prepared to successfully navigate the unique expectations of leading the healthcare built environment.
“Gaidar remains in formation today...” (on the canon of Soviet children’s reading and cultural recycling)
Authors:   Institute of Russian Literature (The Pushkin House), Maslinskaya S. G. ,   Russian Academy of Sciences (Russia, St. Petersburg)
Published: April 2024

The article is devoted to the problem of demand and concomitant reinterpretation of the Soviet literary heritage in the 2000s. The work of Arkady Gaidar, recognized as the best Soviet children’s writer during his lifetime and as an author who fully expressed Soviet values — heroism in the struggle for the establishment of Soviet power and collectivism — in the Soviet period was widely available to readers-children. Both the print runs of his works and the number of reprints (including in school anthologies) were very significant: he was in the top ten in terms of the size of print runs and the regularity of reprints. Based on a study of the history of the publication of Gaidar’s texts from 1926 to 1984, publishing and pedagogical preferences in the selection of works for reprinting have been identified: most often, “The Tale of a Military Secret” was reprinted in impressive numbers, as its ideological content glorified heroic sacrifice in the name of establishing Soviet power. The story “Timur and His Gang” had the same number of reissues as “Military Secret”. In the 1990s, reprinting of Gaidar’s works was sharply reduced, and the choice of what was published also changed: the first place is occupied by “Chuk and Gek”, which depicted everyday family life. In 2000–2022, the story “Timur and His Gang”, which emphasizes the values of class mutual assistance and collectivism, becomes the most reprinted. Publication of other works by Gaidar also demonstrates a noticeable change in emphasis: there is a sharp drop in reissues of the stories “School” and “R. V. S.”, which have temporal contextualization in the historical events of the October Revolution and the Civil War. This allows us to say that the mobilization narrative, which is generally characteristic of Gaidar’s works, is losing its historical conditionality (the Revolution and the Civil War). At the same time, the reprinting of works about peacetime, which takes place in the immediate vicinity of hostilities that require mobilization efforts by both adults and children, have been renewed in the current book offerings for young readers. Recent initiatives to bring Gaidar’s works back into the school curriculum also testify to the reactualization.
Stereotypes of cultural heroes in comic Internet poetry: Their development and destruction
Authors:   Russian State University for the Humanities (Russia, Moscow), Krongauz M. A.
Published: April 2024

The article analyzes modification of cultural stereotypes about famous people in the postfolklore space of small poetry genres that appeared on the Internet in the 2000s and are usually called stishki (short insignificant poems, sing. stishok). The most popular among them are pirozhki (sing. pirozhok) and poroshki (sing. poroshok). We also consider material from other close genres found at the website “Poetory” — https://poetory.ru: ekspromt (impromptu), depressiashka (depressing poem), dve deviatki (two nines), artishok (artichoke). Both real people and fictional characters are the object of research. The article considers stishki about the Soviet cosmonaut Yuri Gagarin and Clara and Karl, characters from a tongue-twister, as well as the postfolklore ties between Beethoven and Van Gogh. The article traces their ties with other characters, both those existing in a common cultural space (for Gagarin it is Korolev, Titov and the like) and those appearing in poetic postfolklore (for Gagarin these are God and Lenin). The convergence of characters can occur not only on the basis of stereotypes, but also on the basis of random similarities, both external to the language (event, thing) and linguistic (for example, coincidence or consonance of names). The “logic of postfolklore” is described, that is, associative links that connect “distant” characters (separated by time or social standing) and form pantheons of postfolklore heroes.
Photos by Eugène Atget as expression of objectivity of architecture: Hôtel de Beauvais
Authors:   State University “Dubna” (Russia, Dubna), Хохлова С. П.
Published: April 2024

The article compares the representation of architecture in French and Russian academic art history, on the one hand, and in Eugène Atget’s photographs, on the other. The starting point for the art historical descriptions is Jacques-François Blondel’s analysis, supported by Jean Marot’s drawings. The choice of characteristics analyzed by Blondel and later researchers reflects the schematism in the understanding of architecture, its distance from the human being, and its lack of existential characteristics. This representation finds correspondence in the illustrative material — in the preference for drawings, plans, frontal point of view, and the absence of the human being in it. Atget’s images, due to the personal characteristics of their author, as well as of photography as an art form in general, reflected those characteristics of architecture which art historians overlooked, and which are related to its fundamental immersiveness and inseparable connection with the human lifeworld. Atget achieves this effect with the help of complex angles, naturalness of visual coverage, and seriality of photographs. “Unadorned” pictures of old buildings correspond to the naturalness of their aging, to actual and potential ruin as an important characteristic of architecture. On the basis of the analysis, the conclusion is reached about the need to revise the subject of architectural studies in the direction of its greater multidimensionality, inseparability from the human being, dynamism and uncertainty.

Published: April 2024

Introduction: Hyperlipidemia is a condition that may lead to many illnesses. The worldwide prevalence of hyperlipidemia is still relatively high. Lactoferrin is a glycoprotein found in mammals and fishes’ epithelial mucosa cells, also known for its protective roles. Objective: This study aims to discover the histopathologic changes in rat’s liver after the intervention of 100, 200, and 400 mg/kgBW lactoferrin. Method: This study involved 30 Sprague-Dawley rats divided into six groups: normal, negative control, statin-treated, dose 1, dose 2, and dose 3. The normal group was given standard feed, while the other groups were hyperlipidemic induced by a high cholesterol diet. The intervention for the statin-treated group was 1.5 mg/kgBW statin, while dose 1, 2, and 3 were respectively given 100 mg/kgBW, 200 mg/kgBW, and 400 mg/kgBW of lactoferrin. After six weeks, all rats were dissected, and the livers’ histopathologic slides were scored with Manja Roenigk scoring. Result: Lactoferrin improved the fatty liver condition. The statistical test results showed that 200 mg/kgBW of lactoferrin caused a significant change in the rats’ liver structures (p < 0.05). Conclusion: 200 mg/kgBW of lactoferrin significantly improved the histopathologic structure of fatty liver
CHALLENGES OF OCULAR TOXOPLASMOSIS TREATMENT IN MULTIPLE DRUG INTOLERANCE SYNDROME: A CASE REPORT AND LITERATURE REVIEW
Authors: Kaur Reena , Tajunisah Iqbal , Juana Azida , Wah Lott Penny Pooi
Published: April 2024

We report a literature review and a case of ocular toxoplasmosis in a patient with multiple drug allergies, who was successfully treated with regular intravitreal clindamycin and subconjunctival dexamethasone. A Malay lady in her twenties presented to us with right eye blurring of vision of 2 weeks duration, which she described as a central scotoma. Visual acuity at presentation was hand movements. Examination revealed intense ocular inflammation. The right eye had anterior segment inflammation of 3+ cells with fine keratic precipitates, whilst the posterior segment revealed papillitis, vitritis, retinitis, choroiditis, vasculitis and hyperpigmented chorioretinal scar inferotemporal to fovea. Ocular coherence tomography showed intraretinal fluid and retinal thickening. Fluorescein angiography showed early hypofluorescence of the lesion with progressive hyperfluorescence and leakage from the optic disc. Immunoglobulin G serology of Toxoplasma gondii was raised and immunoglobulin M levels were normal. The patient developed an allergic reaction with classical antibiotic and antifolate therapy. She was successfully treated with regular two-weekly intravitreal clindamycin and subconjunctival dexamethasone and her best corrected visual acuity was 6/18 at the end of her treatment. Intravitreal injection of clindamycin and subconjunctival dexamethasone is a good option in patients of ocular toxoplasmosis who are allergic to oral medications.
THE ROLE OF EXPRESSIVE ART THERAPY AND NEUROFEEDBACK ASSESSMENTS IN IMPROVING CLINICAL HYPNOSIS ADHERENCE AMONG ANXIETY SUFFERERS
Authors: Koo Kian Yong , Abdullah Azizah Binti
Published: April 2024

Despite worldwide concern on anxiety, preventive measures in public health industries remained scarce. Previous studies found that therapeutic adherence is vital for the treatment efficacy of anxiety sufferers; polyvagal theory may address adherence issues by considering biopsychosocial perspectives. As such, this research intends to generate polyvagal-focused therapeutic guidance in line with anxiety sufferers. This study examines the effectiveness of the Creative Brain Health Intervention (CBHI), which includes expressive art therapy and neurofeedback assessments, as well as clinical hypnosis for anxiety sufferers. The study utilizes a qualitative method with a grounded theory approach to explore helpful and unhelpful factors of CBHI. The study samples were found to have minimal scores at a mild level (on anxiety or stress subscales) of eight (for the anxiety subscale) and 15 (for the stress counterpart) under DASS-21 following a screening procedure. Particularly, the samples were analyzed after CBHI through in-depth interviews for data collection. A total of 45 participants were recruited to generate the outcomes of this study, and the results show that mental healthcare can be enhanced by addressing adherence, stigma, and support through a public system and education, backed by six domains for anxiety treatment and innovative therapeutic approaches. The study recommends early intervention and prevention phases in future research to address stigmas and prevent mental disorder. Resultantly, therapeutic adherence could be enhanced with a polyvagal-focused framework CBHI established for this study. Consequently, the study suggests insights for developing therapeutic guidance to enhance adherence and prevent full-fledged anxiety complexities.

Literacy and numeracy are the abilities of students to use basic mathematics in solving daily life problems, and students should have it. Various studies have shown that Indonesian students' literacy and numeracy skills still need to improve. One of the solutions to this problem is RME, and one of the components that influence this skill is teachers as a facilitator and their experiences. Thus, this research aims to refigure how students who receive Realistic Mathematics Education (RME) literacy and numeracy skills improve based on teacher's experiences. The research subjects are third, fourth, and fifth-grade students in elementary schools in Padang. Three schools were selected for each grade level and taught by three teachers with different experiences. The students were given literacy and numeracy problems before and after RME instruction. The answers were assessed and grouped to examine the student's literacy and numeracy achievement. The research results show that student's literacy and numeracy skills are better with RME learning. Student's literacy and numeracy skills are not influenced by teachers' experience.
Doppler renal resistivity index in horses: a systematic review
Authors: Rosse Nathalia dos Santos , Reis Emily
Published: April 2024

The renal resistivity index is a tool to evaluate the hemodynamics
through arterial resistance. Considering perfusion as one of the first
aspects to be affected upon kidney injury, alterations in renal blood
flow could be especially important for the early detection of kidney
damage. The aim of this systematic review was to retrieve published
studies on equine renal resistivity index (RI) in order to develop a
standardized method of renal ultrasound examination through a
transabdominal approach as well as to evaluate current reference range
for renal RI value in horses. An electronic search in Science Direct,
PubMed, Scopus and Web of Science databases was performed in February
2023 using the terms “RI” OR “resistivity index” OR “IP” OR
“pulsatility index” AND (kidney OR renal) AND (equine OR horse) in
titles, keywords and abstracts. The studies were screened based on
inclusion criteria and variables of interest were extracted. To assess
the methodological quality, the SYRCLES‘s risk of bias tool was used.
From the search, a total of 134 studies were identified and five of them
were considered eligible. The selected studies had been conducted in
healthy non-sedated horses through transabdominal technique. The upper
limit of normality for renal RI was 0.58 ± 0.06 for the right kidney of
untrained horses, which is considerably lower than the value of 0.70
currently used for humans, cats and dogs. There were heterogenous
outcomes among studies, where two out of the five demonstrated
difference between RI value of left and right kidneys and one out of the
five showed increased renal RI value in the elderly compared to foals
and adult animals. Data of RI in horses is still scarce; a normality
standard for renal RI studies in horses would greatly improve comparison
and good quality results to allow clinical application.
Differences in Native and Invasive Fish Larval Occupancy and Detection Probabilities in the Upper Mississippi River
Authors: Yff David J. , Weber Michael J.
Published: April 2024

The Upper Mississippi River (UMR) represents one invasion front to
bigheaded carps Hypopthalmichthys spp. in North America. Agencies
often sample larvae to determine the conditions that bigheaded carp
reproduction occurs, but the ability for conventional ichthyoplankton
sampling to detect bigheaded carp reproduction compared to native fish
is unknown. We used occupancy models to estimate larval bigheaded carp
and native fish larvae detection probabilities and assessed how habitat
type, Julian date, river discharge, and water temperature affect
occupancy. We sampled larvae in pools 18-20 of the UMR every two weeks
at the Iowa, Skunk, and Des Moines River confluences in backwater, side
channel, and thalweg habitats. Detection probabilities increased with
water volume filtered and was lower for larval bigheaded carp than
freshwater drum, gizzard shad, and percids. Freshwater drum and
bigheaded carp larvae had higher detection in thalweg and channel border
habitats compared to backwaters. Occupancy of bigheaded carp peaked on
June 19 at 20°C, increased with discharge, and
declined with coefficient of variation (CV) of water temperature and
discharge. Gizzard shad and percids occupancy peaked on May 24
and increased with CV of water temperature while
occupancy of freshwater drum peaked on July 3 ,
decreased with CV of water temperature, and increased with water
temperature. Our results indicate bigheaded carp are more difficult to
detect than native larvae and identified conditions associated with
larval occupancy that can be used to maximize detection and better
understand when, where, and under what conditions larvae are present
while accounting for imperfect detection.

Published: April 2024

O objetivo do estudo foi analisar o comportamento da relevância do conteúdo informacional da distribuição do valor da DVA (Demonstração do Valor Adicionado), conforme os grupos de interesses classificados à luz da Teoria dos Stakeholders e Shareholders. A metodologia aplicada caracteriza-se em qualitativa, com predominância quantitativa, no período de 2009 a 2018, em 169 empresas brasileiras. Os dados foram organizados em painel, totalizando 1.690 observações, e utilizou-se o modelo de Ohlson (1995) de value relevance ajustado conforme a pesquisa. As variáveis do Vad (Valor Adicionado) foram classificadas em VadShare (Acionistas), VadStake (Stakeholders), StakSoc (Social), StakGov (Governo) e StakTer (Terceiros) e as hipóteses fundamentadas na teoria econômica. Os resultados apontaram que o Vad proporciona um modelo mais adequado e possui influência negativa no preço das ações, confirmando a teoria econômica. A maximização de riqueza aos acionistas é confirmada nos resultados em todos grupos de interesse na distribuição de riqueza - constatou-se que modelo do VadShare é o mais adequado ao ser comparado com o VadStake, StakSoc, StakGov e StakTer. Constatou-se que o período analisado, de crise econômica e política, influenciou no comportamento do valor da distribuição de riqueza, do preço das ações. De forma geral, pode-se inferir que outros fatores podem impactar o preço das ações. Destaca-se como contribuição da pesquisa que tanto a discussão da teoria dos Shareholders e Stakeholders como a análise das evidências empíricas podem ser o despertar de interesse de análise e discussões na academia e maior uso e utilidade da DVA nas empresas e no mercado.

Published: April 2024

Las hojas de stevia (Stevia rebaudiana Bertoni) son consideradas edulcorantes naturales, bajos en calorías e inocuos. Por su parte, los tallos de stevia han sido menos estudiados y se consideran subproductos agroindustriales, aunque representan una buena fuente de fibra con propiedades tecnofuncionales que podría utilizarse como ingrediente alimentario. El objetivo del presente trabajo fue evaluar las propiedades químicas y tecnofuncionales de los tallos de stevia como potencial ingrediente de alimentos funcionales.  Los tallos fueron obtenidos de plantaciones de stevia en Yucatán – México, y se les determinó la composición química proximal y su perfil tecnofuncional considerando la retención de agua y de aceite, la absorción y adsorción de agua y la absorción de moléculas orgánicas. Las determinaciones analíticas fueron realizadas por triplicado y se utilizó un análisis de varianza de una vía para el análisis estadístico de los datos obtenidos. Estos presentaron un alto contenido de carbohidratos (54,84 %), fibra cruda (32,33 %), cenizas (6,99 %) y proteína (4,46 %). Los tallos retuvieron cinco veces su peso en agua y en aceite (5,57 y 5,00 g/g), respectivamente. La capacidad de absorción de moléculas orgánicas fue de 2,09 g/g, la absorción de agua iguala a 4,49 g/g y la adsorción de agua de 0,29 g/g. Los tallos como subproducto agrícola de la cosecha de hojas de stevia son una alternativa funcional para usar en la elaboración de alimentos con potenciales efectos fisiológicos.

An Application of Polymer Nanocomposites Based On Carboxymethylcellulose along with Aluminium (Al) and Copper (Cu) Nanoparticles for Increasing Oil Production
Authors: H Al-Obaidi Sudad
Published: April 2024

As an agent for displacing residual and hard-to-recover oil reserves, polymer nanocomposites based on sodium salts of carboxymethylcellulose (CMC) and aluminium (Al) and copper (Cu) nanoparticles were investigated. It has been shown that polymer nanocomposites are more effective as oil displacement agents than the sodium salt of carboxymethylcellulose itself. Increasing the viscosity of an oil displacement solution can be achieved by varying the concentrations of CMC and nanoparticles. This study thoroughly examined the dynamic viscosities of carboxymethylcellulose (CMC) and polymer nanocomposites that contain CMC and metal nanoparticles (Al and Cu) across various concentrations. The results obtained are robust and reliable. It has been shown that, among polymer nanocomposites containing Al nanoparticles, there is a higher dynamic viscosity compared to its Cu nanoparticle counterpart at equivalent concentrations. This work proposes a simulation reservoir model to enhance oil recovery from hard-to-recovery reserves. Through this reservoir model simulation, the oil recovery factor was calculated using filler sand and oil extracted from a hydrocarbon field. The experimental data revealed the most effective concentration of CMC and nanoparticles for oil displacement. The results suggest that polymer nano composites composed of different metal nano powders have varying impacts on oil displacement efficiency. In this experiment, a composition consisting of Al nanoparticles with a size range of 50-70 manometers (nm) proved to be more successful as an oil displacement agent than a polymer nanocomposite made of Cu nanoparticles and CMC. At these concentrations and combinations, the highest oil recovery factors were achieved.
Natural treatment approaches for varicose veins: A brief review of the literature
Authors: Büyükyıldırım Tuğsen , Şenol Deniz Fatma Sezer
Published: April 2024

Chronic venous insufficiency (CVI) is a widespread condition affecting millions worldwide. Each year, approximately 150,000 new patients are diagnosed with CVI, and nearly $500 million is used in the care of these patients. The venous system has sturdy valves and muscle pumps that keep blood flowing back to the heart against gravity. The inadequacy of these systems leads to difficulties in blood circulation, blood pooling, and venous hypertension, all which have the potential to lead to the development of varicose veins, edema, discomfort, alterations in the skin, and potentially even the formation of ulcers. Conditions that induce CVI are genetic predisposition, obesity (body mass index greater than 30), continuous standing/sitting work, age, pregnancy, gender, and lifestyle. Conventional venous insufficiency treatments include compression therapy, surgical interventions like vein stripping, and sclerotherapy. Venoactive drugs used in conservative treatment have the potential to enhance both varicose veins and symptoms associated with chronic venous disorders throughout all stages of venous insufficiency. In addition to synthetic drugs, naturally derived coumarins, flavonoids, rutin derivatives, pycnogenol, micronized purified flavonoid fraction, and saponosides are essential in the treatment. Medicinal plants and natural compounds are highly preferred for treating CVI and varicose veins due to their biological activities, such as anti-inflammatory, antioxidant, and vascular tone improvement. The present review provides a concise overview of the utilization of natural compounds and plant extracts in treating varicose veins, both in medical practice and traditional folk medicine.

The study was conducted during spring and summer 2022 at Mare Savin garden centre (Trappes, France) to confirm plant protection properties of some dairy products. Indeed, for crop protection, the search for new non-chemical fungicides useful, durable, affordable and efficient as active substances (a.s.). These suitable products, especially from natural origin called BioControl Agents (BCA) are acceptable to civil society (i.e., low-concern profile, and absence of residues of concern) are of paramount importance as the number of chemical solutions has drastically decreased in recent years. When natural substances from the plant origin are plethoric in literature and some are approved as Plant Protection Product (PPP), natural substances from the animal origin repertoire are sparsely represented in PPP a.s., but lately a few substances have obtained a European Union (EU) active substance approval (i.e. sheep fat, blood meal, fish oil, chitosan hydrochloride from crab shell). Dairy products may also exhibit crop protection properties like whey and cow milk are two of these new BCAs. The corresponding applications under EU PPP regulation (EC) n° 1107/2009 were granted as basic substance according Article 23, respectively in 2016 for whey and 2020 for cow milk for protection of vegetable against mildew and agricultural tools disinfection. These basic substances are approved for an unlimited period of time with no Market Authorisation, for all Europe without zone or Member State consideration, and with no Maximum Residue Limits (MRL). Later, an extension of use for vineyards protection against diseases was granted for whey in 2021.

Liquid fertilizer applicator based on Variable Rate Application (VRA) is a technology that is used to fertilize in a controlled and precise manner. This study aims to improve the effectiveness and efficiency of the fertilization process of chili plants. The development carried out is esp32 cam which serves to detect chili plants that lack elements. The method used is input of the nutritional needs of chili plants, spray doses of each plant, and a microcontroller to control applicator components such as sprayer pumps, selenoid valve, and esp32 cam. In this liquid fertilizer applicator there are 2 pipes, each pipe has 4 nozzles. The results of laboratory tests show that the discharge of liquid fertilizer sprayed follows the input results of the nutritional needs of chili plants. The discharge released on the PWM sprayer motor varies from 40 to 100% resulting in very different discharge variations in each PWM spray. The efficiency of this VRA-based liquid fertilizer applicator reaches 87% or an increase of about 14.7% from the applicator before development. Regression analysis of dimmer level to spraying discharge showed a function y = 6.3016x + 18.937 with an R 2 of 0.9921. While the regression analysis of the dimmer level of the applicator speed obtained the function y = 94.075x + 20.203 with an R2 of 0.9936. Keywords: Chili plants, Liquid, Fertilizer, Applicator, VRA.

This study investigates the possible factors determining the success of m-payment adoption in Generation Z using the basic Unified Technology Acceptance and Use of Technology (UTAUT) model based on previous research. A theoretical model derived from previous research that combines factors from the acceptance model of UTAUT with relevant m-payment factors (Trust, Perceived Security, Network Externalities). The sample includes 735 participants from three cities in Indonesia. Structural equation models are used to analyze and develop theoretical models. Only four hypotheses can be accepted based on the analysis of the seven hypotheses proposed. Trust, Perceived Security, Performance Expectancy, and Social Influence positively and significantly impact Behavioral Intention. Meanwhile, Facilitating Conditions, Effort Expectancy, and Network Externalities are insignificant to Behavioral Intention. There are many research models for adopting m-payments, but in developing countries, including Indonesia, the cellular penetration rate is already very high. However, the acceptance of m-payments in various trade transactions is still embryonic, especially in Generation Z. Therefore, this research presents a comprehensive investigation of the factors that influence the adoption of m-payments in Generation Z in Indonesia.

Specialization is one of the important things in focusing the student's field of study. At one university that has a faculty of computer science, there is an Informatics Engineering undergraduate study program which is divided into two specializations, namely intelligent systems and software engineering design. At one university that has a faculty of computer science, there is a bachelor's program in Informatics Engineering which is divided into two specializations, namely intelligent systems and software engineering design. students find it difficult to choose one of the specializations in the informatics engineering study program. To overcome these problems, the authors provide solutions in the form of ideas that can recommend students in determining specialization. In this problem, the algorithm that will be used is the C4.5 algorithm based on forward selection plus adaboost. The results of the specialization classification use the selected attributes and iterate over the cross-validation so as to produce the right accuracy. Testing the C4.5 algorithm produces an accuracy of 93.89% and the C4.5 algorithm based on forward selection produces an accuracy of 94.44% while using the C4.5 algorithm based on forward selection with the addition of adaboost produces an accuracy of 94.63%. Based on these tests, it proves that there is an increase in accuracy by adding selection and adaboost features to the C4.5 algorithm.

This research aims to find the symbolic meaning of the Melinting dance in Wana village, East Lampung. This research uses an interdisciplinary approach consisting of the disciplines of Anthropology of Art and Sociology of Art. The type of research used is qualitative with descriptive analysis methods. Data collection techniques consist of observation, interviews and document study. The data validity technique used is the source triangulation technique. The data analysis technique is carried out in three stages, namely by reducing data, presenting data, and drawing conclusions. The research results show that the symbolic meaning of the Melinting dance can be seen from the main elements (movement) and supporting elements (musical accompaniment and clothing). The symbolic meaning of the Melinting dance in movement is being open, respecting each other, being good at maintaining attitudes and behavior, maintaining the dignity of the family, being responsible and having the courage to look after oneself. The symbolic meaning of the Melinting dance accompanied by music is an expression of joy, community skill and peaceful life. Meanwhile, the symbolic meaning of fashion is that people's behavior must be in accordance with the teachings of the Islamic religion.
