Behavioural Reasoning Theory Perspectives: Hospitality Accounting System Adoption
Authors: Dwiyanti I Gusti Kadek Anggiriska , Dewa Gede Wirama
Published: September 2024

This study delves into the behavioural intention to adopt Hospitality Accounting Systems (HAS) in Bali's villa accommodation sector, employing the Behavioral Reasoning Theory (BRT) framework. Through a representative sample of 363 villa owners or managers, utilising the PLS-SEM technique, it explores how personal values, reasons for and against, and attitudes influence HAS adoption intentions. The findings underscore the significant impact of attitude on adoption intentions, with values significantly affecting attitude and reasons for and against. Interestingly, while reasons for directly influence intention, reasons against have the opposite effect. Future research avenues could explore additional factors influencing technology adoption and delve into the long-term implications of technology integration on organisational performance and user satisfaction. This study enriches theoretical frameworks and offers actionable insights for enhancing technology adoption in the hospitality industry and beyond.
Assessing Response Format Effects on the Scaling of Marketing Stimuli
Authors: Peng Ling , Finn Adam
Published: September 2024

Multi-item rating scales are the accepted solution for achieving reliable and valid measures in the social sciences. Issues not fully resolved include the optimal number of response categories, choice of semantic rating versus Likert form, and the appropriateness of mixing positively and negatively expressed items. While there is considerable empirical research on these issues, it addresses the scaling of respondents and is yet to produce consensus as to the most appropriate practice. In marketing, multi-item scales are not only used to scale consumer respondents, they are used to scale marketing stimuli. This article examines these response format issues when the primary objective is to scale marketing stimuli rather than consumers using generalisability theory criteria for data quality. G-study website assessment data using different response formats are used to compare their effects on the observed variance components and G-coefficients for websites. Conclusions are drawn for the most appropriate response format to use in marketing studies that scale marketing stimuli.

Published: September 2024

Aim: The prevalence of childhood obesity is rapidly increasing, making it one of the most common nutritional problems globally. This study aimed to investigate the impact of education using the creative drama technique on obesity awareness and healthy nutrition-exercise behavior among middle school students.
Material and Methods: This single-group pre-test-post-test quasi-experimental study was conducted in a state middle school in a Western Black Sea Region province between October 2023 and January 2024, involving 156 middle school students selected through random sampling. A six-session face-to-face education program on obesity prevention and healthy nutrition was implemented. Data collection forms included a Demographic Information Form, an Obesity Awareness Scale, and a Nutrition-Exercise Behavior Scale. Data collection forms were administered to students before (t1) and one month after the education (t2).
Results: The mean age of the participating students was 12.33±0.92. Only 3.8% of students had previously received education on combating obesity through healthy nutrition. There was a significant increase in students’ obesity awareness (t1=2.99±0.17, t2=3.54±0.20) and nutrition-exercise behavior scores (t1=153.76±13.07, t2=165.1±11.57) after the education.
Conclusion: Interactive and participatory learning through the creative drama technique effectively increased students’ obesity awareness and promoted healthy nutrition-exercise behaviors. Education focusing on hands-on experiences and active engagement was found to be successful in enhancing students’ awareness of obesity and encouraging healthier lifestyle choices.
Association of Insulin Resistance and Ectopic Fat Accumulation with HOMA Indices: A Single-Centre Observational Study
Authors: Emir Sevde Nur , Emir Servet
Published: September 2024

Purpose: The aim of this study was to investigate the relationship between non-alcoholic fatty liver disease (NAFLD), non-alcoholic fatty pancreas (or pancreatic) disease (NAFPD) and HOMA indices in obese patients without a diagnosis of diabetes mellitus, using ultrasound (US) as a common non-invasive diagnostic tool during routine examinations. Methods: In this single-centre, retrospective study, the records of patients who applied to the obesity outpatient clinic in 2023 were reviewed. Digital records were scanned and patients with abdominal ultrasound reports indicating age, gender, body mass index(BMI), fasting plasma glucose, fasting plasma glucose, C-peptide level and degree of pancreatic and hepatic steatosis were included in the study. Patients with known chronic disease or diabetes mellitus and patients with specific drug use were excluded from the study. Homa indices were calculated using fasting plasma glucose and C-peptide levels. Results: A total of 62 patients were included. Body mass index was 39.1, 91% had NAFLD and 82% had NAFPD. There was a significant positive correlation between BMI and NAFLD and NAFPD. HOMA scores revealed a statistically significant impact of NAFLD on insulin resistance (HOMA-IR) and insulin sensitivity (HOMA-S) but not on beta-cell function (HOMA-B). No significant effect of NAFPD on HOMA scores was observed. Conclusion: The findings underline the association between NAFLD and insulin resistance and highlight the metabolic burden of ectopic fat deposition in obese patients. In contrast, there was no significant correlation between NAFPD and either insulin resistance or beta-cell function, suggesting that the metabolic impact of pancreatic steatosis may be different. These findings may help to guide clinical strategies for detecting and treating metabolic disorders in obesity.
Determining The Relationship Between Diet Inflammatory Index Score, Depression and Chronotype In Individuals with Metabolic Syndrome: An Example of a Training and Research Hospital
Authors: Ahıskalıoğlu Kübra , Kenger Emre Batuhan
Published: September 2024

Aim: This study aimed to examine the relationship between the depression, chronotype and Dietary Inflammatory Index score in individuals diagnosed with metabolic syndrome.
Material and Methods: This study included 100 individuals with metabolic syndrome. The Depression-Anxiety Stress Scale was utilized to assess the depression, stress, and anxiety levels of the participants. Chronotypes were determined using the Morningness-Eveningness Questionnaire, and the Dietary Inflammatory Index (DII) was calculated based on a three-day food consumption record.
Results: Of the participants, 53% were women and 47% were men. The depression (10.64±3.91), anxiety (10.38±3.51), and stress (13.12±3.89) scores were significantly higher in the "evening type" group. Female participants had significantly higher depression scores (9.68±4.39) compared to male participants (8.00±3.35) (p=0.033). Analysis of the Dietary Inflammatory Index (DII) scores revealed that women had a more pro-inflammatory diet (3.23±5.69). Additionally, a positive correlation was observed between depression scores and carbohydrate consumption (r=0.264, p=0.002), while a negative correlation was found with the percentage of protein intake (r=-0.336, p=0.001).
Conclusion: The study revealed that the majority of individuals with metabolic syndrome exhibit an evening chronotype and are at increased risk for depression, anxiety, and stress. Additionally, it was found that these individuals tend to follow a pro-inflammatory diet. Therefore, it is recommended that the treatment of individuals with metabolic syndrome includes the assessment of their chronotypes, nutritional habits, and psychological states.

Infância e memória em meios tons na poesia de Manuel Bandeira
Authors: Lombas Miguel , Tettamanzy Ana Lúcia Liberato
Published: September 2024

O presente artigo aborda as possibilidades epistemológicas da infância tendo em vista as dimensões da memória em poemas de Manuel Bandeira. Neste estudo, a memória será compreendida como as experiências e acontecimentos vividos ou expressos de forma tanto individual como coletiva (Hal- bwachs, 1990). O poeta se vale da oralidade como recurso poético na evocação do passado (Bâ, 2010). Nesse sentido, imagens da infância aparecem com frequência associadas ao acervo cultural e identitário do menino nordestino doente, precocemente confrontado com a morte e saudoso do repertório popular presente na gama de conhecimentos cotidianos emanados no verbalismo de can- tigas de roda, brinquedos, propagandas, falas “erradas” e estórias orais. A materialidade do cotidiano e o mistério poético desentranhado do lugar comum, centrais na poética bandeiriana e marcos de efervescência do primeiro modernismo (Arrigucci Jr., 1987), evidenciam o notório comprometi- mento do poeta com o seu lugar e tempo, porém manifestam igualmente resquícios das práticas e pensamentos coloniais e racistas constituintes da “neurose cultural brasileira” (Gonzalez, 2020) que se mantiveram ao longo do século XX.

À Grupont (Commune de Tellin, Province de Luxembourg, Belgique), une couche de minerai de fer sédimentaire du Dévonien inférieur à moyen (Emsien/Eifelien) renferme localement des quantités importantes de sidérite riche en manganèse qui, en se transformant en goethite et hématite, a également produit des espèces comme la lépidocrocite et la ranciéite. Cette dernière espèce est nouvelle pour la Belgique et elle ne semble abondante que dans les environnements riches en sidérite altérée. Le minerai de Grupont, pouvant renfermer jusqu’à 50 % en poids de fer, est parfois erronément qualifié d’hématite oolithique, or la proportion d’hématite n’est que d’un quart contre trois quarts pour la goethite. De plus, les oolithes sont rares et ne sont observées que dans certaines parties des blocs de sidérite et jamais dans le minerai à proprement parler.
Пространственно-временные особенности обитания обыкновенного канюка в Среднем Прииртышье
Authors: Б.Ю. Кассал
Published: September 2024

При обращении к доступным средствам борьбы с грызунами, в частности, увеличению возможности использовать естественных врагов, лидирующее положение занимает обыкновенный канюк, специализированный миофаг. В Среднем Прииртышье степной обыкновенный канюк уже в марте в степном/остепненном (суббореально-семиаридном) климатическом районе (к. р.) в процессе еще не завершенной весенней миграции начинает брачный сезон, который в лесостепном (суббореально-семигумидном) климатическом районе определяет восстановление старых многолетних и создание новых брачных пар. В лесных (таежном/бореальном и подтаежном/бореально-суббореальном) климатических районах брачные пары занимают гнездовые участки, обустраивают гнезда и выкармливают птенцов. Часть брачных пар гнездится в лесостепном и степном/остепненном к. р., но в них концентрируются в основном неполовозрелые особи. В августе сеголетний молодняк расселяется, переходя к самостоятельному образу жизни; предотлетное распределение охотничьих участков обыкновенного канюка в большинстве случаев происходит на уровне семейных групп. Осенняя миграция проходит массово и в короткие сроки, завершаясь к началу октября. Все время нахождения в Среднем Прииртышье мелкие мышевидные грызуны, с преобладанием полевок, составляют основу рациона степного обыкновенного канюка.

When turning to available means of rodent control, in particular, increasing the ability to use natural enemies, the leading position is occupied by the common buzzard, a specialized myophage. In the Middle Irtysh region, the steppe common buzzard already in March in the steppe/steppe (subboreal-semihumid) climatic region, in the process of still incomplete spring migration, begins the mating season, which in the forest-steppe (subboreal-semihumid) climatic region determines the restoration of old perennials and the creation of new mating pairs. In forest (taiga/boreal and subtaiga/boreal-subboreal) climatic regions, mating pairs occupy nesting areas, build nests and feed chicks. Some of the mating pairs nest in the foreststeppe and steppe/steppe areas, but mostly immature individuals are concentrated in them. In August, the young of this year settle, moving to an independent lifestyle; Pre-migration distribution of hunting areas of the common buzzard in most cases occurs at the level of family groups. Autumn migration occurs en masse and in a short time, ending by the beginning of October. Throughout its stay in the Middle Irtysh region, small mouse-like rodents, with a predominance of voles, form the basis of the diet of the steppe common buzzard.

Authors: Laberge-Carignan Audrey , Mercier Florence , Larivière Dominic , Couture Raoul-Marie
Published: September 2024

Selenium is an essential micronutrient, whose mobility in cold region underpins both crop quality and the aquatic food web. Our objective is to test for the influence of temperature (4 and 23°C) on Se sequestration in undisturbed sediments using flow-through reactors (FTR) containing fresh or aged organic matter (OM), under environmental relevant low Se conditions. Se speciation along with concentration of ancillary parameters (pH, DOC, NO3-, NO2-, Fe(II), SO42-, HS-) were measured in the outflow during 8 experimental phases in which Se concentrations were sequentially increased. FTR sequestered most of the Se, with fresh OM removing 50% more than aged OM. Temperature response was lower for selenite than for selenate. At 100 nM inflow selenite, in the presence of fresh OM, Se effluxes, comprising of undefined organic Se, were of 0.94 nM d-1 at 23°C and of 0.85 nM d-1 at 4°C. In contrast, at 100 nM inflow selenate, effluxes were of 0.9 nM d-1 at 23°C and an order of magnitude higher at 8.4 nM d-1 at 4°C. Outflow Se was composed of selenite and organic Se species at 23°C and of selenate at 4°C. We hypothesize that selenate reduction was controlled by microbial processes, influenced by temperature, while selenite transformation proceeded via abiotic reactions.
Rapid 3D printing of unlayered, tough epoxy-alcohol resins with late gel points via dual-color curing technology
Authors: Mayer Florian , Laa Dominik , Koch Thomas , Stampfl Jürgen , Liska Robert , Ehrmann Katharina
Published: September 2024

Additive manufacturing technologies and in particular vat photopolymerization promise complex structures that can be made in a fast and easy fashion for highly individualized products. While the technology has upheld this promise many times already, some polymers are still out of reach or at least problematic to print reliably. High-performance epoxide-based resins, which are regulated by chain transfer via multifunctional alcohols, are a typical example for resins with late gel points, which require long irradiation times and high light intensities to print. Therefore, we have developed a dual-colour printing approach where rapid radical curing of a soft, wide-meshed polymer network facilitates fast and easy 3D structuring of the subsequently slow curing step growth formulation at an orthogonal initiation-wavelength regime. Thereby the methacrylate system acts as a scaffold for an uncured epoxide alcohol system during the printing process, which is then cured with UV light post-printing. This way tough alcohol-regulated epoxy-systems become accessible to vat photopolymerization achieving outstanding high-resolution 3D printed parts without significant layering effects. The demonstrated wide-meshed matrix-assisted printing approach has the potential to make a multitude of slowly curing resins accessible to vat photopolymerization techniques, at low irradiation intensities and high curing speeds.

The engineering of conjugated oligo- and polymers at the micro- and nanoscale is crucial for developing advanced functional materials and electronic devices, such as OFETs, OLEDs, and sensors, due to their electronic and optoelectronic properties being highly dependent on their supramolecular order. This research investigates the self-assembly and aggregation behavior of a series of amphiphilic oligothiophenes with varying hydrophilic/hydrophobic balances, synthesized through palladium-catalyzed cross-coupling reactions. The molecular structures were characterized using NMR and mass spectrometry, and their optical properties were examined by UV-Visible absorption spectroscopy, revealing distinct absorption maxima influenced by the molecular architecture. Dynamic light scattering (DLS) and cryotransmission electron microscopy (cryo-TEM) studies demonstrated the formation of spherical aggregates with diameters around 200 nm in aqueous solutions, consistent with scattering measurements indicating low critical micelle concentrations (cmc). Adsorption isotherms and Brewster Angle Microscopy (BAM) highlighted the interfacial properties and interactions of these amphiphilic molecules at air/water interface, emphasizing the impact of their structural features on self-assembly and material properties. These findings underscore the potential of amphiphilic oligothiophenes in tuning solution self-assembly, morphology, and optoelectronic characteristics for applications in advanced electronic materials.

Published: September 2024

Nonadiabatic dynamics simulations complement time-resolved experiments by revealing ultrafast excited-states mechanistic information in photochemical reactions. Understanding the relaxation mechanisms of photo-excited molecules finds application in energy, material, and medicinal research. However, with substantial computational costs, the nonadiabatic dynamics simulations have been restricted to ultrafast timescales, typically less than a few picoseconds, thus neglecting a wide range of photoactivated processes occurring in much longer timescales. Before developing new methodologies, we must ask: How well do the popular nonadiabatic dynamics methods perform in a long timescale simulation? In this study, we employ the multiconfiguration time-dependent Hartree (MCTDH) and its multilayer variants (ML-MCTDH), ab initio multiple spawning (AIMS), and fewest- switches surface hopping (FSSH) methodologies to simulate the excited-states dynamics of a weakly- coupled multidimensional Spin-Boson model Hamiltonian designed for a long timescale decay behavior. Our study assures that despite having very different theoretical backgrounds, all the above methods deliver qualitatively similar results. While quantum dynamics would be very costly for long timescale simulations, the trajectory-based approaches are paving the way for future advancements.
Atomic-level Insights into the Highly Conductive Lithium Thiophosphate Solid Electrolytes with Exceptional Stability Against Lithium Metal
Authors: Sen Huseyin Sener , Karasulu Bora
Published: September 2024

Despite the wide range of emerging solid electrolytes with promising characteristics, such as high ionic conductivity, the inherent thermodynamic instability against lithium metal remains a significant challenge. We have previously introduced a new family of solid electrolytes based on thiophosphates with inherent stability against metallic Li anode and high conductivity [JACS REF]. In this study, we employ density functional theory (DFT) together with ab initio molecular dynamics (AIMD) simulations to investigate the diffusion mechanisms and underlying factors contributing to the high ionic conductivity of these novel Li-P-S ternary electrolytes, including Li7PS2, Li5PS, Li8P2S, and Li11P3S. Our findings reveal that these materials exhibit ionic conductivities comparable to the well-known superionic conductor, Li7P3S11, positioning them as promising candidates for solid-state battery applications. Additionally, we assess the thermodynamic stability of these ternaries in contact with lithium metal anodes, a critical consideration for practical battery use. Unlike Li7P3S11, which forms a solid-electrolyte interphase, the novel Li-P-S ternaries exhibit remarkable stability against Li metal anode due to their unique Li2S-like structural framework. The absence of a solid-electrolyte interphase layer is particularly significant, as it eliminates additional resistance at the electrolyte-anode interface, a common challenge in many solid-state battery systems. Our study not only highlights the suitability of these novel ternaries, particularly Li5PS, as high-performance solid electrolytes but also underscores the importance of structural design in developing next-generation battery materials. The ability of these materials to maintain high ionic conductivity and stability over extended periods makes them ideal candidates for future solid-state lithium batteries, offering a pathway to safer, more efficient, and longer-lasting energy storage solutions.

Authors: Bello A. G. , Hussin H. , Muhammad M.
Published: September 2024

Purpose: This study explores the application of Discrete Event Simulation (DES) using FlexSim software to enhance the operational efficiency of a Liquefied Petroleum Gas (LPG) bottling plant. The primary goal is to ensure that the LPG plant can safely and efficiently meet escalating market demands, thereby prioritising all stakeholders' safety.
Design/Methodology/Approach: The research design focused on empirical research and experimental simulation modelling. The study began with collecting and analysing one month of LPG plant data, laying the foundation for developing a simulation model. Verification and validation processes ensured the model's accuracy, enabling the investigation of various operational scenarios. The key performance indicators like First Time to Failure (FTTF), Time Between Failures (TBF), and Time to Repair (TTR) were analysed. The availability rates were 77% from actual data and 76% from simulations, showing that the model is suitable for real-world use.
Findings: This study's findings underscore the potential impact of proactive maintenance strategies and operational enhancements as practical and applicable approaches to optimising performance. The analysis also revealed significant improvement opportunities through what-if scenarios: increasing MTBF by 100%, reducing MTTR by 50%, and raising conveyor speed by 15%.
Research Limitation: The study's dependence on a systematic literature review could restrict its ability to capture the industry's real-time dynamics.
Practical Implication: Implementing proactive maintenance strategies and operational enhancements as practical approaches can reduce downtime and costs and promote productivity and safety.
Social Implication: Optimising plant operations will help maintain supply chain stability with the growing demand for LPG.
Originality/Value: This work contributes valuable insights and recommendations, establishing a foundation for informed decision-making in the LPG bottling sector.
The behavior of the generalized solution of the initial-boundary value problem for the nonlinear parabolic equation
Authors: Shevchuk Daryna , Stiepanova Kateryna
Published: September 2024

Within the framework of this work, we study the behavior of the generalized solution (or the so-called energy solution) of an interesting initial-boundary value problem (namely, the Cauchy-Dirichlet problem is considered) for nonlinear parabolic equation. The research is carried out in a cylindrical area. A structural condition is imposed on the parameters of the equation corresponding to the slow diffusion process. So, in the article we are dealing with the distribution of the substance concentration in space and time, taking into account the initial and boundary conditions. This process has a practical aspect and is used in physics and engineering, for example, to study the diffusion of matter in environments with variable concentration or chemical influence. Solving such problems allows obtaining important data on the evolution of the system and predicting its behavior in various conditions. In the work, as a result of our research, several integral ratios, various estimates and inequalities were established, which lead to the need to analyze the behavior of the differential system, which in turn makes it possible to establish the presence of the solution localization property. So, relying on the well-known results regarding the behavior of the solution of the resulting differential system, it is possible to find a condition that guarantees the localization of the solution carrier for the Cauchy-Dirichlet problem under study.

BackgroundThe study focused on understanding infant and young child feeding practices (IYCF) among Muslim mothers in the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM), Philippines.ObjectiveRecognizing the cultural and religious sensitivities associated with these practices, the research aimed to identify influencing factors and assess the influence of advertisements on maternal decisions regarding infants' and children's diets.MethodsA total of 74 Muslim mothers with infants 6-23 months old were recruited and participated in the focus group discussions (FGD). Ten FGD sessions were conducted in Maguindanao Province, Philippines from July to August 2021. Verbatim transcriptions of audio-recorded discussions were transcribed into Microsoft Word files and QSR NVivo version 12 was used in the coding and analysis of the transcripts.ResultsMothers exhibited limited awareness of such important complementary feeding issues as preferring fruits and vegetables while avoiding junk food as chips. IYCF information came primarily from health workers and other mothers - their own mothers, mothers-in-law, and midwives. Television commercials were identified as particularly influential in shaping maternal feeding decisions.ConclusionsThere was a diversity of breastfeeding practices and limited knowledge, especially of complementary feeding among these Muslim mothers. Both traditional beliefs and marketing were said to influence feeding choices. This underscores the need for culturally-sensitive interventions and targeted educational initiatives to enhance maternal knowledge and advocate for optimal infant feeding practices within Muslim communities, as well as regulation of the marketing of commercial infant foods.

Although child wasting is preventable, it is a significant public health problem in Sri Lanka. Imported ready-to-use therapeutic food (RUTF), called BP-100, is part of the locally used treatment of severe acute wasting. However, Sri Lanka has faced economic barriers in providing this product. Two RUTF bars were developed in our laboratory based on global nutrient and other specifications (RUTF-1 and RUTF-2). Nutrient and microbiological analyses were within acceptable limits and shelf life was determined. This observational study was conducted to test the acceptability of locally produced RUTFs among children aged 2-4 years old, a first step in its possible use in place of imported versions. 56 children aged 2-4 years old in two preschools located in poor urban settings were included. These two RUTF bars and BP-100 were given to the children for a total period of three weeks (3 days of each product), with 3 to 4 days of interval in between. At the beginning, weight and height of the children were measured. A five-response hedonic scale was used to test acceptability. Mean daily intakes, and any apparent adverse effects were recorded. A taste test on the acceptability of RUTF and BP-100 among mothers or guardians was carried out on the last day of the trial. The colour, taste, smell, and texture of both RUTF bars were compared to BP-100. Overall acceptability of RUTF-1 (p=0.000) and RUTF-2 (p=0.02) was observed compared to BP-100 among both children and mothers. No adverse effects were reported. Further analysis indicated that there was no significant difference between locally produced RUTFs and BP-100 on acceptability in relation to sex, age, wasting, or stunting; however, a difference was noted related to ethnicity (p=0.000). In conclusion, locally produced RUTFs are as acceptable as BP-100. There is a need to assess the effectiveness of RUTFs while building partnerships with the food industry for sustainable production.
Sobre el área cultural Quito tras un siglo de investigaciones arqueológicas
Authors: Torres Jiménez Kyra
Published: September 2024

A partir de los resultados de la investigación para la tesis de maestría de la autora1, se plantea larelevancia del concepto de área cultural Quito para entender a las sociedades que se asentaron enlos Andes del norte del actual Ecuador, al sur de la cuenca del río Guayllabamba, en la meseta deQuito y valles aledaños, durante el período de Integración y contacto Inca. A pesar de que no seha llegado a un consenso general en cuanto a la denominación y caracterización de las mismas, seconsidera que existe suficiente evidencia para definir un área cultural diferenciada de Caranquiy Carchi-Nariño, al norte; Yumbo, al occidente, y Cosanga-Quijos, al oriente. La informaciónobtenida de investigaciones arqueológicas e históricas respalda la existencia de poblacionesbajo un modelo político heterárquico, en donde no se evidencia un solo núcleo urbano, sino unagran cantidad de asentamientos dispersos, que comparten rasgos culturales y lazos de índolesociopolítica y económica.
Peregrinaciones por el valle del río Chibunga: dinámica política y social en la veneración puruhá al volcán Chimborazo en Riobamba, Ecuador
Authors: Jadán V. Mary
Published: September 2024

Desde la época de Jijón y Caamaño, son limitados los estudios sobre la sociedad puruhá queintegran la investigación de sitios arqueológicos relacionados con el vulcanismo. Este artículoda importancia al patrón de asentamiento y su vinculación con el volcán Chimborazo. Utilizaevidencia relevante sobre los eventos eruptivos del volcán, el análisis estratigráfico de los sitiosarqueológicos y la investigación de las fuentes etnohistóricas. Se determina que los pueblos seasentaron en el valle del río Chibunga y peregrinaron para la veneración a la montaña, porque elrío nace en sus deshielos y conduce directamente a espacios rituales. La estratigrafía en Guano,Macají y San Juan revela las erupciones constantes que los puruháes resistieron y confirma laactividad eruptiva del Chimborazo, alternando con períodos de estabilidad entre 400 d.C. y 1533d.C. La conexión con el nevado reveló una compleja relación política y social entre las élites yla sociedad puruhá.
Cabellos despeinados y palabras alborotadas
Authors: Crespo Coello Patricio
Published: September 2024

En algunos políticos contemporáneos se detectan gestos y discursos disruptivos con lo que podría considerarse un comportamiento correcto. La cortesía y la sobriedad, están siendo reemplazadas por formas discursivas que comunican una ruptura cultural. ¿Se trata de un síntoma menor o los políticos despeinados y con discursos alborotados están expresando algo más profundo? Las formas corteses del comportamiento político tienen una compleja historia íntimamente relacionada con las costumbres cotidianas. Comprender esa relación en la cultura política puede constituir un interesante punto de partida para interpretar los cambios actuales en determinados relatos y en especial para detectar algunos elementos de interpretación de lo que ciertos sectores llaman la “guerra cultural”.

Purpose: Temporal lobe resection can be categorized as either temporal lobe epilepsy (TLE), which involves cortical resection confined to the temporal lobe, or temporal plus epilepsy (TPE), which entails temporal resection along with involvement of additional extratemporal regions. We compared these forms within a pediatric population.Methods: We identified 136 patients who underwent temporal resection over a 17-year period and investigated the differences in the clinical profiles and seizure outcomes between TLE and TPE.Results: Of the total sample, 110 patients (80.9%) presented with TLE and 26 (19.1%) with TPE. Significant differences were observed between the groups in age at seizure onset (TLE: 6.3 years, TPE: 0.9 years; P=0.001), age at epilepsy surgery (TLE: 14.2 years, TPE: 9.2 years; P=0.002), the proportion of patients with a history of infantile epileptic spasm syndrome (IESS) (TLE: 6 [5.5%], TPE: 8 [30.3%]; P<0.001), electroclinical presentation with IESS or Lennox-Gastaut syndrome (LGS) (TLE: 11 [10.0%], TPE: 13 [50.0%]; P<0.001), the presence of focal temporal hypometabolism on positron emission tomography (TLE: 74 [68.5%], TPE: 11 [44.0%], P=0.021), and the use of intracranial electroencephalogram monitoring (TLE: 58 [52.7%], TPE: 21 [80.8%]; P=0.009). Furthermore, multivariate analysis identified the epileptic presentation of IESS or LGS as a significant predictor of TPE (P=0.049). The rates of seizure outcomes of International League Against Epilepsy class 1–3 at 1 year of follow-up were 83.8% for the entire cohort, 89.1% for TLE, and 61.5% for TPE (P=0.002).Conclusion: TPE appears to represent a substantial subset of pediatric temporal resections. The variation in seizure outcomes between groups underscores the importance of predicting TPE in advance, with implications for effective treatment planning.

In this study, a millimeter-wave far-field range antenna measurement system is proposed for W-band monopulse antenna measurements. Since the W-band monopulse antenna installed in radar systems has many input/output ports, multiple calculations are required to measure all the ports. We propose a system structure capable of the simultaneous measurement of multiple channels to quickly and accurately measure the performance of a monopulse antenna. The proposed measurement system includes a multi-channel rotary joint, a pair of diplexers, and multiple vector network analyzer extenders. In addition, an RF sub-system is implemented to reliably measure the phase of the W-band radiation pattern. It utilizes a shared local oscillator source and external power amplifiers for the transmit and receive paths. Employing the proposed multi-channel antenna measurement system, the sum/difference channels of a monopulse antenna were simultaneously measured according to the azimuth angle. In addition, a comparison of the far-field measurements provided by the proposed system and the near-field measurements was conducted.
