Intelligent image recognition using lightweight convolutional neural networks model in edge computing environment
Authors: Qiu Lingling
Published: June 2024

In order to enhance the performance of intelligent image recognition, this study optimizes the image recognition model through lightweight convolutional neural networks (CNNs) and cloud computing technology. The study begins by introducing the relevant theories and models of edge computing (EC) and lightweight CNNs models. Next, this study focuses on optimizing traditional image recognition models. Finally, the effectiveness and reliability of the proposed model are experimentally validated. The experimental results indicate that, when recognizing 1000 images, the average recognition times per image on cloud servers and edge servers are 13.33 ms and 50.11 ms, respectively. Despite the faster speed of cloud servers, the performance of edge servers can be improved by stacking servers. When the number of edge servers reaches 4, their recognition speed surpasses that of the cloud server model. Additionally, comparing the latency and processing time between EC and cloud computing architectures, it is observed that, with an increase in the number of processed images, the average processing time per image in the EC architecture remains relatively stable and consistent. In contrast, the average processing time gradually increases in the cloud computing architecture. This indicates a significant impact of the number of images on the processing rate of the cloud computing architecture. Therefore, as the time gap in processing between cloud computing and EC increases, the advantages of the EC architecture become more apparent. This study’s significance lies in advancing the development of deep learning technology and providing possibilities for its widespread practical application. The contribution of this study lies in promoting the development of EC and lightweight neural network models, offering valuable references and guidance for practical applications in related fields.

Published: June 2024

The use of image fusion technology in the area of information processing is continuing to advance in depth thanks to ongoing hardware advancements and related research. An enhanced convolutional neural network approach is developed to fuse visible and infrared images, and image pre-processing is carried out utilising an image alignment method with edge detection in order to gain more accurate and trustworthy image information. The performance of the fast wavelet decomposition, convolutional neural network, and modified convolutional neural network techniques is compared and examined using four objective assessment criteria. The experimental findings demonstrated that the picture alignment was successful with an offset error of fewer than 3 pixels in the horizontal direction and an angle error of less than 0.3∘ in both directions. The revised convolutional neural network method increased the information entropy, mean gradient, standard deviation, and edge detection information by an average of 46.13%, 39.40%, 19.91%, and 3.72%. The runtime of the modified approach was lowered by 19.42% when compared to the convolutional neural network method, which enhanced the algorithm’s performance and boosted the effectiveness of picture fusion. The image fusion accuracy reached 98.61%, indicating that the method has better fusion performance and is of practical value for improving image fusion quality.
Developing a fuzzy comprehensive assessment model for English translation for college studentso
Authors: Huang Yang
Published: June 2024

College students are learning a foreign language must know how to translate the spoken or written content from the respective language into English. These approaches do not help the college students to develop the capacity for rational thinking and adequate the motivation for the English translation. The educational principles are not in line with the qualities of the students in the typical English translation classroom teaching, and the teaching methods are out-dated. In the older process of the teaching English translation, many unreliable, vague aspects need to be considered, such as recognizing students’ fundamental English knowledge, unique circumstances, language proficiency, cultural differences, and the ambiguity of the source language. The main issue with the current English translation evaluation methodology is that it cannot be easily to deal with thecomplex fuzzy indices when judging the accuracy of the student translations. An algorithm named FCAM-AHP-ANFIS is proposed to provide an effective and accurate method for evaluating and predicting students’ English translation outcomes to overcome the traditional shortcomings. According to the proposed approach, students can learn about passive translation, but they may struggle to actively improve their translation skills. College students can benefit from the decision-making aid provided by the extensive evaluation technique due to its high availability and precision. The fundamental benefit of the fuzzy technique over more traditional forms of the assessment is that it accounts for the ambiguity and uncertainty of the making judgments at the human level and provides a coherent framework that includes the indistinct findings of the several steps in evaluating an English translation. The Fuzzy Comprehensive Assessment Model (FCAM) is a decision-making method that uses the fuzzy logic to assess the quality of English translations among the college students. The Analytic Hierarchy Process (AHP) is employed to calculate each criterion’s relative importance and determine the optimal weighting for each criterion utilized in the assessment model. The Adaptive Neuro-Fuzzy Inference System (ANFIS) is used to analyze the translated data and generate predictions for the students’ translation outcomes. The experimental outcomes show the accuracy of the English translation assessment scores are 95.6% with 97% precision, 96% recall, and 96.5% of f1-score metric in addition to Root Mean Square (RMSE) and Mean Absolute Error (MAE).
How Parkinson’s Disease-Linked LRRK2 Mutations Affect Different CNS Cell Types
Authors: Bailey Hannah M. , Cookson Mark R.
Published: June 2024

LRRK2 is a relatively common genetic risk factor for Parkinson’s disease (PD), with six coding variants known to cause familial PD. Non-coding variation at the same locus is also associated with sporadic PD. LRRK2 plays a role in many different intracellular signaling cascades including those involved in endolysosomal function, cytoskeletal dynamics, and Ca2+ homeostasis. PD-causing LRRK2 mutations cause hyperactive LRRK2 kinase activity, resulting in altered cellular signaling. Importantly, LRRK2 is lowly expressed in neurons and prominently expressed in non-neuronal cells in the brain. In this review, we will summarize recent and novel findings on the effects of PD-causing LRRK2 mutations in different nervous system cell types. This review will also provide novel insight into future areas of research at the intersection of LRRK2 cell biology, cell type specificity, and PD.
Does gender matter in Supported Employment? A qualitative study of participants’ experiences
Authors: Witte Ingrid , Strandberg Thomas , Gustafsson Johanna
Published: June 2024

BACKGROUND: In Sweden, gender differences have been found in standard vocational rehabilitation as well as in evidenced-based methods such as Supported Employment (SE). However, these quantitative findings have not been followed up by qualitative research to clarify the issue. OBJECTIVE: To explore participants’ experiences of participating in an SE intervention and the influence of gender on their experiences. METHOD: Semistructured interviews with 10 women and 7 men participating in SE in Sweden were conducted. Qualitative content analysis followed by a gender analysis were performed using the material. RESULTS: The participating men and women had different background characteristics. Overall, the participants shared the same experiences of SE. They valued a trustful relationship with the employment specialist and the diversified and individualized support from the employment specialist. Unlike the men, the women had experienced difficulties receiving SE from authorities, and when receiving SE, they expressed the value of a slow start, being challenged, and whole-life support. CONCLUSION: The findings might moderate the rapid job principle in SE and indicate the need to acknowledge that the path to employment might look different, depending on the participants’ gendered experiences and living conditions, for SE to be more successful for both men and women.

The tear film lipid layer plays a crucial role in maintaining ocular surface homeostasis by preventing excessive evaporation of the aqueous layer and reducing heat transfer from the corneal and conjunctival surface. The lipid composition of the tear film is unique and consists of two main layers: the outer (nonpolar lipids) and the inner (polar lipids). The thick outer layer of the tear film is composed of non-polar lipids that lack internal distributed charge, while the thin inner layer is formed by polar lipids with positive and negative charges at the ends of the molecule. Both types of lipids are synthesized in the meibomian glands (MG) and contribute to tear film stability. Meibomian gland dysfunction (MGD) alters the composition and physical properties of lipids, leading to pathological changes in both the MG and tear film. In meibomian gland dysfunction (MGD), the meibum thickens and acquires a higher melting point than normal. This leads to a decrease in the amount of nonpolar and amphiphilic lipids in the meibomian gland secretion and tear film. Consequently, the protective effect of the tear lipid layer is impaired, and its stability is compromised. Lipid mapping analyzes the lipid composition of biological samples, such as tear fluid, to study the mechanisms of the development and progression of various ocular surface diseases, including dry eye syndrome, MGD, and recurrent blepharoconjunctivitis. This method provides fundamental data on the properties of the tear film in various ocular surface diseases. It has the potential to establish hallmarks of disease course and develop personalized treatment approaches for specific clinical cases.

Infodynamics, Information Entropy and the Second Law of Thermodynamics
Authors: Jaffe Klaus
Published: June 2024

Information and Energy are related. The Second Law of Thermodynamics states that entropy continuously increases, applies to changes in energy and heat, but it does not apply to information dynamics. Changes in energy and information are coupled but have completely different dynamics. Infodynamics has made clear that Thermodynamic Entropy and Information Entropy are distinct concepts. Total Energy contains Free Energy and Thermodynamic Entropy, whereas Total Information or Information Entropy contains Useful Information and Noise, both of which may be gained or lost in irreversible processes. Increases in Free Energy of open systems require more Useful Information, reducing or increasing Thermodynamic Entropy. Empirical data show that the more Free Energy is created, the more Useful Information is required; and the more Useful Information is produced the more Free Energy is spent. The Energy – Information relationship underlies all processes where novel structures, forms and systems emerge. Although science cannot predict the structure of information that will produce Free Energy, engineers have been successful in finding Useful Information that increases Free Energy. Here I explore the fate of information in irreversible processes and its relation with the Second Law of Thermodynamics, showing that distinguishing between Thermodynamic Entropy and Information Entropy, and disentangling its interactions, is fundamental in advancing our understanding of thermodynamics of irreversible processes.

Authors: Fatmawati  , Puteri Aliah Ramadhani , Huda Humairah Binti
Published: June 2024

The human civilizations have been using plants and herbs for their rich sources of phytonutrients and bioactive compounds. Polyphenols are one of the groups of beneficial compounds found naturally, they include a wide variety of molecules and are divided into 4 main categories, which are flavonoids, phenolic acids, lignans, and stilbenes. It is estimated that more than 10,000 flavonoid compounds have been isolated and then identified, with the results finding that the majority of flavonoids are widely accepted as therapeutic agents. It is found in various flowers, fruits, and leaves such as red peppers, celery, parsley, chamomile, mint, and ginkgo biloba. Flavonoids are known for their anti-inflammatory properties using a mechanism that is thought to be different. The mechanism used may include an enzyme inhibition mechanism for enzymes that regulate transcription factors. This has a very important role, one of the roles being the control of mediators involved in an inflammatory process. The study for this systematic review was conducted without a time constraint using scientific databases such as Google Scholar and ScienceDirect, with 5 years’ time limitation. Previous research has validated the pharmacological characteristics of some flavonoids and their potential health advantages.

Background: Diabetes mellitus (DM) is a metabolic disorder characterized by an elevated blood sugar level due to problems with insulin synthesis, effect, or both. Various clinical signs follow DM: Hyperglycemia, polydipsia, polyuria, and polyphagia. Worldwide prevalence is high and predicted to be 592 million by 2035. Animal models are used in the study of diabetes due to ethical issues. Although the streptozotocin (STZ) model is frequently used, it is unreliable due to unexplained acute toxicity and effective dose variability. Objectives: This research was conducted to determine the effective dose regimen of STZ for inducing diabetes in Wister rats. Methods: A total of 28 male Wistar rats (160-190 g) were randomly divided into 4 groups (each 7 rats) and monitored for 21 days after diabetes induction with STZ: Control (CTR), diabetics (DIA)1 (60 mg/kg STZ), DIA2 (60 mg/kg STZ twice at 0 and 24 hours), and DIA3 (60 mg/kg STZ thrice at 0, 24 and 48 hours). Plasma glucose was determined with a glucometer. Body weights, feed intake, and fecal output were weighed with a digital balance, while water intake and urine output were measured with a measuring cylinder. Analyses of data obtained were performed using a one-way ANOVA and Tukey’s test at a significance level of P≤0.05. Results: There was a significant (P<0.05) decrease in body weight of the diabetic groups (-15.53%±1.2%, -26.8%±1.2%, -28.5%±1.9%) compared to the CTR (10.5%±2.5%). There was a significant (P<0.05) increase in fasting blood glucose concentrations (135.2±9.0, 273.2±6.5, 257.0±5.3 mg/dL) in the people with diabetes compared to the CTR (79.3±1.1 mg/dL). Water intake (56.9±0.9, 72.1±1.7, 77.8±5.5 mL), feed intake (19.4±0.6, 23.3±1.9, 42.1±2.1 g), voided urine (6.34±0.1, 8.39±0.88, 9.8±0.50 mL) and voided feces (10.4±0.26, 11.7±0.43, 8.5±0.17 g) in the diabetic groups increased significantly (P<0.05) compared to the CTR (26.5±0.8 mL, 13.4±0.3 g, 1.84±0.08 mL, and 6.5±0.33 g, respectively). Conclusion: The dose regimen of 60 mg/kg STZ administered intraperitoneally twice (24 hours apart) sustained diabetes for 21 days. We recommend adopting this dose regimen in STZ-induced diabetic studies in male Wistar rats.

Changes in Subgrade Insulation Conductivity With Varying Moisture Content
Authors: Asher Lauren
Published: June 2024

The climate is rapidly changing, raising the groundwater level and causing more severe flooding. As flood waters rise, they saturate the soil and penetrate foundations. In Canada, there are two ways of insulating a foundation: externally against the soil or internally, like in a wall assembly. The saturation of external insulation by flood waters will change its thermal conductivity, but the effects of cyclic wetting and drying have not been well documented. There are two aspects to the study of this impact, WUFI simulation and lab testing. Three types of insulation were used in the lab testing, extruded polystyrene (XPS), closed-cell polyurethanesprayfoam,and rockwoolmineral wool,whichcanall be usedinground contact.Thepurpose is to determine if insulation can return to its pre-wetted thermal conductivity after several flooding events. The results are promising, but this topic will need to be studied over a longer period.
Evaluating the Performance of Chiller 1 in Daphne Cockwell Complex (DCC) Building
Authors: Kassem Mohammad
Published: June 2024

A significant amount of the energy consumed in large buildings is used to operate the chiller plant. This research investigated the performance of water-cooled chiller in a multipurpose building to pave the way for future chiller optimization research. The objective was to pinpoint key trends and relationships between the chiller operating conditions and energy performance. To reach this objective, the research was undertaken in three steps; 1) the existing chilled water system and its control was documented, 2) time series of operating data was collected and analyzed, 3) the chiller efficiency was calculated. The results showed that the chiller has reached its optimal performance at COP of 11.24 at the following set of conditions: PLR = 46%, cooling output between 801.27 and 814.69 kW, and chilled water supply temperature between 6.3-7.5¬∞C. This research also highlighted energy-saving opportunities that can be implemented in the central cooling plant to enhance the performance of the chiller.
The Development of Ferrocene and Vinyl Pyridine Containing Triphenylamine-based Dyes for Integrated Light Harvesting Devices Involving Dye-sensitized Solar Cell Technology
Authors: Singh Tavneet
Published: June 2024

As new solar cell technologies are developed, their adoption would likely be enhanced through novel applications. To this end, this thesis explores the development of two new types of organic dyes for integrated devices that incorporate dye sensitized solar cell (DSSC) technology; notably, smart windows and motion sensing. DSSCs have the advantage over other solar technologies in that they are optically transparent and can be implemented into various design concepts including bifacial windows or coatings. Because the powerhouse of the DSSC is molecular in nature, they also function in diffuse light, which means they can be employed in technologies thatcould be used in any lightcondition. Furthermore, the dye is the sensitizer and can be tuned further for the desired application. To this end, this thesis examines the development of two different dye families for two different applications. After a brief and generic introduction in Chapter 1, Chapter 2 visits the idea of using ferrocene (Fc) as an additional redox-active donor component to the organic dye. Fc is known for its redox robustness, and the goal to have this functionality added is to enhance the stability of the photo-oxidized dye, such that these dyes and corresponding DSSC devices could be employed in integrated devices, such as smart supercapacitor windows. After examining the structure-property relationships of this dye family, very poor efficiencies will prevent their deployment, and this will be fully articulated in Chapter 2. Chapter 3 explores the potential of appending vinyl pyridinium electron withdrawing groups in the dye architecture (analogous to the Fc-derivatives of Chapter 2). Ultimately, the goal of this chapter was to examine structure-property relationships where DSSC devices could be transformed into motion-sensing windows. In theory, this would be achieved by the development of shunt-like dyes, where specific wavelengths would decrease the performance when absorbing diffuse, long wavelengths of light. Unfortunately, synthetic limitations prevented the completion of the target dyes, but dye precursors are examined for their potential in this application. Owing to the uniqueness of each application, Chapters 2 and 3 have an extensive introduction. Further context can be found at the end of each chapter with conclusions and future work.
Characterization of Liposomal Release Temperature Using a Low Field Magnetic Resonance System
Authors: Noori Khalid
Published: June 2024

The use of liposomes as chemotherapeutic carriers has been the subject of many research studies, with emphasis on enhancing the therapeutic index by increasing effect on cancer cells and reducing side effects. An important parameter to characterize for thermosensitive liposomes, TSLs, is the release temperature, Tr, the temperature at which liposomes release most of their content. By loading liposomes with a contrast agent such as Mn2+, a benchtop NMR system can be used to determine Tr through incremental heating. In this work, the release temperature was extracted from relaxometry measurements of Mn2+-loaded TSLs. Tr values were then compared with transition temperature values, Tm, the temperature at which liposomes’ bilayer changes state, obtained by a standard technique. The difference of the average values between Tr and Tm was approximately 0.5 oC. The discrepancy is due to artifacts produced by the standard technique. Nonetheless, Tm can be used to predict Tr.
Couples Coping With Multiple Sclerosis: Does Dyadic Coping Congruence Matter?
Authors: McGarragle Kaitlin
Published: June 2024

Multiple sclerosis (MS) affects 90,000 Canadians and 25% of MS patients report their relationship is negatively affected by MS. Patient and partner wellbeing are also correlated therefore, examining coping from a dyadic perspective is warranted. The objectives of this thesis were to explore individual and conjoint dyadic coping (DC) strategies and DC congruence in couples high and low in relationship functioning (RF). MS patients and their partners completed quantitative measures and purposive sampling was used to categorize couples as high or low in RF. Interviews were conducted with participants separately and results were analyzed using thematic analysis. High RF couples generally engaged in adaptive strategies (e.g., illness acceptance) and low RF couples generally engaged in maladaptive strategies (e.g., conceptualizing MS as an individual issue). DC congruence was not as important as the additive effect of positive DC strategies. Contextual factors like life stage, financial stress, and culture influenced DC strategies.
Symbiont community changes confer fitness benefits for larvae, but not juveniles, in a vertically transmitting coral
Authors: Olivares-Cordero Daniel , Quigley Kate , Timmons Courtney , Kenkel Carly
Published: June 2024

Coral reefs worldwide are threatened by increasing ocean temperatures because of the sensitivity of the coral-algal symbiosis to thermal stress. Reef building corals form mutualistic symbiotic relationships with dinoflagellates (family Symbiodiniaceae), including those species which acquire their initial symbiont complement from their parents. Changes in the composition of symbiont communities, through the mechanisms of symbiont shuffling or switching, can modulate thermal limits. However, the role of shuffling in coral acclimatization is understudied and work to date has largely focused on adults. To quantify the fitness consequences of changes in symbiont communities under a simulated heatwave in early life-history stages, we exposed the larvae and juveniles of the widespread, vertically transmitting coral Montipora digitata to heat stress (32°C) and tracked changes in their growth, survival, photosynthetic efficiency, and symbiont community composition relative to controls. We found negative impacts with warming in all fitness-related traits, which varied significantly among larval families and life-stages. Surviving larvae exposed to heat exhibited changes in symbiont communities that favoured types that are canonically more stress tolerant. Compared to larvae, juveniles showed more rapid mortality under heat stress and their symbiont communities were largely fixed regardless of temperature treatment, suggesting an inability to alter their symbiont community as an acclimatory response to heat stress. Taken together, these findings suggest that capacity for symbiont shuffling may be modified through development, and that the juvenile life-stage is more at risk from climate warming.

Der «Bürgerblock» im antikommunistischen Kampf gegen die Initiative für eine einmalige Vermögensabgabe 1922: eine Analyse von Diskurssträngen auf Plakaten und Postkarten
Authors: Metzger Thomas
Published: June 2024

The debate over the initiative of the Swiss social democrats for a capital levy in 1922 was conducted harshly within a polarized political landscape. On the part of its bourgeois opponents, the demand for a capital levy was dubbed a robbery that endangered society, stemming from alien communist ideas and ultimately aimed at the creeping socialization of the economy. The bill was stylized as an attack on “the people” as a whole. The dis- course strands appear particularly pointedly in the numerous postcards and posters against the initiative, which are analyzed in this article.
Internet : une simple révolution technologique
Authors: Rieffel Rémy
Published: June 2024

In the 1990s and 2000s, the growth of the Internet ushered in a technological revolution which enabled the use of new communication media. This went hand in hand with the diffusion of a powerful imaginary (free access, freedom transparency) which is, however, misleading since technologies do not determine by themselves how people use them. It is therefore necessary to think, at the same time, about technical mediation and social mediation. The Internet has also fostered new forms of cultural expression and unprecedented collaborative practices among users. But it remains a hierarchical world – hence the need to put the idea of a « cultural revolution » into perspective.

Why did we decide to take the plunge and, above all, to continue teaching environmental history? Personal interest alone cannot explain it. Other explanations include political, social and student considerations. Similarly, a large part of this article presents a teaching sequence on Chernobyl, which has been tested by students at the HEP Vaud who gave their feedback. It also explains how the sequence can be modified to use it with classes. This course has shown an interest not only by the students, but also by the pupils. It has rein- forced our interest in developing the teaching with reference to what we consider as a new historiographical configuration.
Migrationsgeschichte aus Kinderperspektive. Einsatzmöglichkeiten des Buchs «Verbotene Kinder: Die Kinder der italienischen Saisonniers erzählen von Trennung und Illegalität» von Marina Frigerio im Geschichtsunterricht der Sekundarstufe I
Authors: Kaufmann Helen
Published: June 2024

The article outlines a lesson unit on the topic of migration history for secondary level I which deals with biographical self-presentations of children of Italian seasonal migrants. Based on these individual cases from the context of Switzerland between 1950-1990, students develop an understanding of the effects of (seasonal) migration on families and especially on the children of migrants as well as their scope for action. In addition, students train their skills in analyzing testimonies of witnesses. With a research task about « forbidden children » in Switzerland today, they establish a connection to their present living environment.

Published: June 2024

This article presents an historical exhibition on the contemporary metamorphoses of child protection, examined from a gender perspective. Based on data collected during an NRP 76 research project Welfare and Coercion, our exhibition tackles the mechanisms of invisibilisation and exclusion that specifically affected young girls in care during the 20th century (gendered representations and differential treatment). The article explains how the exhibition was constructed, and the difficulties or limits that were encountered during its genesis.
Kinderarbeit in Fabriken: Das Beispiel der Spinnerei Kunz in Windisch AG
Authors: Baumann Max
Published: June 2024

At the beginning of industrialization in Switzerland in the first half of the 19th century, many 7 to 14 years old children had to work in factories. In this article, sources are used to report on the example of Heinrich Kunz’s mechanical spinning mill in Windisch, Aargau. Boys and girls were often employed for dirty jobs: cleaning halls, sorting waste, oiling the spinning machines, and this initially for up to twelve or more hours a day. In the process, they missed school lessons, which were required by law. The factory owner did not comply with the regulations and came into conflict with the education authorities.

allanamiento de domicilio en el Ecuador según él Código Orgánico Integral Penal y la posible vulneración al Debido Proceso RESUMEN
Authors: Velásquez-Zambrano Edgar
Published: June 2024

El presente artículo se ha desarrollado con el objetivo de determinar si el procedimiento de la diligencia de allanamiento en el Ecuador en relación con el Código Orgánico Integral Penal, se está llevando de una manera adecuada o si está vulnerando los derechos de las personas. Para lo cual se aplica un tipo de estudio descriptivo con enfoque cualitativo, cuyo propósito consiste en ilustrar con datos reales el exceso en los procedimientos de los allanamientos, que muchas veces provocan violación a los derechos humanos, ocasionando también daños físicos y materiales. Como resultado se expone que el debido proceso, concierne a una serie de derechos para que una persona pueda ejercer de manera adecuada su defensa, y que los procedimientos jurídicos que se realicen tengan plena observancia de los principios fundamentales reconocidos por los instrumentos internacionales, así como por la Constitución del Ecuador, con lo que busca evitar acciones arbitrarias por parte del Estado, en este sentido, el procedimiento de allanamiento de domicilio para que pueda ser ejecutado tiene que tener una correcta motivación jurídica, puesto que se vulneran derechos fundamentales tales como la inviolabilidad de domicilio, así como los derechos a la dignidad humana, integridad personal, seguridad jurídica y garantía al debido proceso y por tanto deben existir indicios irrefutables que induzcan a realizar dicha acción con la finalidad de tener resultados fructíferos para los fines de la investigación, además en comparación con las legislaciones penales de Perú, Argentina y Venezuela, se debería contemplar para el procedimiento que se establezcan horarios en los cuales se pueda ejecutar el allanamiento, así como tener la presencia de testigos que certifiquen el respeto de los derechos. También es importante contar con disposiciones sancionatorias para autoridades y personal partícipe de los hechos, cuando en consecuencia se han vulnerado los derechos constitucionales y la operación resulta infructuosa para los fines de la investigación.
Política punitiva incoherente en materia de contravenciones
Authors: Mendoza-De la Cruz Maria
Published: June 2024

La investigación tiene como objetivo identificar los criterios en la aplicación objetiva de la norma contravencional desde la perspectiva de la proporcionalidad y racionalidad, garantizando lo establecido en el ordenamiento jurídico penal ecuatoriano. Se plantea como problemática que las contravenciones como infracciones diferenciadas de los delitos por ser de menor gravedad, deben sancionarse proporcionalmente a la culpabilidad del infractor, caso contrario se estaría evidenciando una arbitrariedad normativa y vulnerando lo establecido dentro del marco legal penal y constitucional. Es un estudio jurídico realizado desde una línea metodológica crítica, analítica, descriptiva, y propositiva que busca dar una explicación real de la norma en los casos de contravenciones penales, e incluso las características o problemas presentes con respecto a la acción punitiva y herramientas jurídicas aplicables brindadas por la normativa legal. Se concluye que existe vulneración de los principios de proporcionalidad, tutela judicial efectiva y de mínima intervención en la aplicación de la pena privativa de libertad en contravenciones.

Authors: Rojas-Vargas Sofia
Published: June 2024

ABSTRACT
Objectives: To determine the risk factors associated with the development of Hellp Syndrome (HS) in pregnant women attended at the Instituto Nacional Materno Perinatal, 2018-2021. Materials and methods: The study is a retrospective cross-sectional analysis using a case-control design. Twenty-five hundred medical records were collected and 196 cases and controls with Hellp syndrome (HS) were selected following eligibility criteria. A data collection form including variables and study dimensions was used. For the analysis, SPSS software was used, applying frequency techniques and Pearson's Chi-square tests to evaluate associations. Results: In cases of Hellp syndrome (HS), higher frequencies were observed in single and cohabiting women, representing 16.8% (p = 0.583); with primary education level in 20.4% (p = 0.195). Regarding age, 12.2% of SH cases were women between 30 and 32 years of age (p = 0.640). A higher proportion of cases were found with a history of arterial hypertension, with 29.1% (OR: 1.230), and in those with malnutrition, with 27.6% (OR: 1.780). There was no significant association with parity, but a higher frequency of cases was observed in nulliparous women, with 17.9% (OR: 1.538), and in pregnant women with a gestational age of 40 weeks, with 6.1%. Conclusions: Malnutrition is the statistically significant risk factor associated with the development of SH.
