Published: January 2024

Das Stadtteilarchiv Ottensen ist ein gemeinnütziger Verein. Begründet durch seine Entstehungsgeschichte, grenzt er sich schon bei der archivischen Erschließung und Bewertung von historischen Quellen von Kriterien staatlicher und universitärer Institutionen ab. Zudem geht er auch bei seiner Digitalisierungsstrategie eigene Wege, bei der die Digitalisierenden selbst eine komplexe Rolle spielen. Partizipation und Niedrigschwelligkeit sind prägende Eigenschaften dieser Bildungsarbeit, die besondere Herausforderungen mitbringen, aber auch große Potenziale und Chancen bergen.

A comparative analysis of two surgical treatment variants for a unilateral longitudinal sacral fracture was carried out in three possible localization of the fracture line: outside the zygapophysis, inside and directly on the zygapophysis. Two variants of implants were considered: cannulated sacroiliac screws and a similar variant in combination with a bilateral lumbar-pelvic transpedicular structure. Analysis and selection of the most rational surgical treatment variant was carried out with the help of biomechanical and computer modelling methods. Surgical treatment variants were evaluated on the basis of investigated succes criteria. Finite-element modelling of static loading of the vertebral-pelvic complex segment was carried out. Displacements and equivalent stresses in bone tissues and implants were analyzed. From the biomechanical point of view, the installation of a transpedicular screws in combination with sacroiliac screws was the most rational variant of surgical treatment. This conclusion is valid for all simulated cases of the fracture line localization. The most unstable fracture variant was a one-sided longitudinal fracture of the sacrum passing through the zygapophysis.

Neurological gait disturbances require long-term gait rehabilitation. According to existing research results, robot-assisted gait training devices are designed to improve patient’s walking capabilities and to eliminate the operator's physical overloading. The aim of this paper is to present an ergonomic analysis of commercially available robot-assisted gait training devices, including both the operators and patients postures during robot-assisted gait training therapy. This ergonomics analysis was performed on the Hocoma’s Lokomat Pro, involving five randomly chosen device's operators and ten adult and children patients who received gait therapies on the day of the experiment. Both evaluators concluded that the most problematic points, from aspects of safety and fatigue for the operators, were the preparation process of the device, device adjustments to each patient individually, and the noise produced by the device. Subsquently patients mostly struggled with the device's ramp and uncomfortable harness. It was noted that although the Lokomat Pro is the most widely used robot-assisted gait training device with many advantages that contribute to improved patient ́s gait capacities, like in every medical device, there is always room for improvement. Research and development of robot-assisted gait training devices is a long-term process requiring multidisciplinary cooperation. The cooperation represents an enriching experience for a whole team of specialists and ensures that the product meets the criteria for the end-users.

In the literature, there are many examples and assumptions about the possible effect of dysfunction of the temporomandibular joint and general dental diseases on the state of a very important vascular artery, namely the internal carotid artery, the kinking and coiling in it, which can lead to the development of the stroke and ischemic disease of the brain. Nowadays, these diseases are one of the most frequent causes of severe disability and premature death of people. Unfortunately, at present there is no comprehensive explanation of influence mechanism of a person’s dentition on the damage of the vital vascular line that connects and unites the work of the brain and the heart. These discrepancies and contradictions can be eliminated after developing the biomechanical model of the influence of the temporomandibular joint dysfunction on the internal carotid artery. In order to correctly solve this problem, it is necessary to know the mechanical properties of the tissues located between the temporomandibular joint and the internal carotid artery. In this article, we selected the experimental technique, determined the theory that describes the behavior of the tissue in this experiment, selected and manufactured equipment, simulated the experiment in the ANSYS software package and compared the simulation results and theoretical calculation of the experiment. The simulation coincided with experiment with good accuracy, as a result the elastic modulus for areolar tissue E = 3 MPa was determined.

This research examines the religious communication strategy (da'wah) carried out by the 'Ngaji Asyik Ahad Malam' community at the Street Cafe Esemday, Mojosongo District, Surakarta City. Using qaualitative methods with an ethnographic approach, the results of this study show that millennials Muslims, those who join 'Ngaji Asyik Sunday Malam' tend to be less interested in the religious activities held in the formal and conventional manner, which require attending religious places such as mosques, mushalla, or Qur'an Learning Place (TPQ). However, millennials currently are more like religious activities that are elaborated in contemporary public spaces. In other words, they need the presence of innovative concepts for religious activities that are relevant and able to understand the millennial culture, and do not discredit them as well.

No se puede ignorar la importancia de ver más allá de las apariencias, y descubrir la verdad sobre sí mismo y el mundo que lo rodea. Desde la perspectiva de la hermenéutica anagógica, es posible abordar diversos textos para entender cómo la visión y la contemplación conducen a la perfección de la vida. Este artículo quiere ser un acercamiento al primer Canto del Purgatorio de la Divina Comedia y a dos pasajes bíblicos del Evangelio según San Lucas 18, 35-43 y 19, 1-10 que a mi juicio comparten un tema común: la visión y la contemplación, en pasivo ser visto y en activo ver.
Desafíos en los planes de estudio de la educación media superior en Oaxaca
Authors: Ceballos-López Mario Samuel
Published: January 2024

Los currículos empleados en las instituciones de nivel medio superior en la ciudad de Oaxaca se encuentran desactualizados y desfasados de las necesidades correspondientes a la realidad actual; esta situación genera un rezago más allá del ámbito educativo, el cual se hace evidente en la comunidad. En primera instancia se aborda el origen de los planes de estudio ocupados para la educación media superior en México, mismos que cuentan con una base de hace más de seis décadas y no han recibido mayor tratamiento o actualizaciones a profundidad. También se analizan las características del modelo educativo en funciones en cuanto al nivel medio superior, comprendido a su vez por los subsistemas, entre ellos, los bachilleratos generales y tecnológicos. Se examina por medio de las materias dispuestas y su respectiva clasificación por bloques, de acuerdo a la Subsecretaría de Educación Media Superior, así como sus metas centrales, sus modificaciones recientes y la relación con los intereses de los estudiantes, quienes consideran a este nivel educativo en mayor medida como paso y no como un logro para darle continuidad a su vida en un sector profesional. Por último, se plantean las necesidades del mundo actual, las cuales van más allá de la diseminación de datos duros; deben tener como objetivo principal elevar la calidad de vida de los jóvenes, y a su vez de la sociedad, para ello, los planes de estudio requieren estar enfocados en satisfacerlas, y no sólo introducir elementos relativamente nuevos en las clases.
Concepciones de participación en estudiantes mexicanos de tres sistemas diferentes de bachillerato
Authors: Ochoa-Cervantes Azucena
Published: January 2024

La participación es el eje del cual podemos educar para la ciudadanía y formar actores sociales. Es importante conocer las concepciones que se tienen acerca de la participación en la escuela, pues es ahí donde se organizan procesos de socialización y enseñanza. Por tal razón, se realizó un estudio cualitativo para analizar el contenido de la producción gráfica acerca de la participación en estudiantes de educación media superior. La población fue de 70 estudiantes de tres bachilleratos públicos de Querétaro, México, con distinto modelo educativo. Los resultados muestran que en la concepción de participación predominan representaciones asociadas a la dimensión pedagógica y acotada al ámbito académico. En los tres tipos de bachillerato, la tendencia se repite. Consideramos que el ejercicio de la ciudadanía puede concretarse en la escuela mediante la participación; sin embargo, es necesario que existan mecanismos en todos los ámbitos de la vida escolar.

OBJECTIVES Current regulations for Korean firefighters primarily emphasize exercise during working hours without specifying particular exercise methods. This study aims to evaluate the exercise intensity of the stepwise Korean Firefighter Fitness Program (KFFP) using Kinect-based mixed reality device (Virtual mate, VM), considering the demanding 24-hour shift work and high physical strength requirements. The objective is to assess its potential as one of the exercise methods and provide valuable insights.METHODS CResearchers recruited 30 participants to evaluate the exercise intensity based on the cardiopulmonary responses induced by the Stepwise Korean Firefighter Fitness Program (KFFP) using Virtual Mate (VM). Initially, the participants' resting heart rate, maximum heart rate (HRmax), and maximum oxygen consumption (VO2max) were measured. Subsequently, researchers monitored the participants' cardiopulmonary responses by employing portable gas analyzers and wireless heart rate monitors while implementing the Stepwise KFFP with VM. Exercise intensity related to cardiopulmonary responses was recorded using both absolute parameters (VO2, HR) and relative parameters (%VO2max, %HRR, %HR). Researchers utilized repeated measures analysis of variance for statistical analysis.RESULTS The analysis of the stepwise KFFP using VM showed significant increases all parameters as the program advanced(p<.001). VO2 increased from around 19.4 ml/kg/min in Step 1 to approximately 22.8 ml/ kg/min in Step 3. Similarly, %HRR rose from roughly 40.6% in Step 1 to about 53.9% in Step 3.CONCLUSIONS Upon evaluating the stepwise KFFP based on the exercise intensity levels recommended by ACSM, it is confirmed that the stepwise KFFP using VM comprises both moderate-intensity and highintensity exercises. This approach is deemed effective and can serve as a fitness management method for firefighters working in 24-hour shift patterns that demand high fitness levels.

THE EFFECTS OF SHAPE AND LIQUID PROPERTIES ON PRESSURE SWIRL ATOMIZER IN-NOZZLE FLOW
Authors: Tonini Simona , Conti P. , Cossali G. Elvio
Published: January 2024

The internal flow in pressure swirl atomizers is numerically predicted by performing large eddy simulations and using a volume of fluid approach. The output of the numerical model is validated by comparing it with three databases of experimental measurements obtained on large-scale pressure
swirl atomizers available in the open literature. A simplified analytical model previously developed
by the authors, which relates the swirl intensity to the thickness of the fluid exiting the nozzle, is
used to analyze the flow behavior in three pressure swirl atomizers, with large differences in the injector geometry, the operating conditions, and the fluid thermophysical properties. This simple relationship is found to hold for the three pressure swirl atomizers, with small changes of the parameter that accounts for energy losses, while data obtained with relatively small variations of the injector geometry are found to collapse on the same curve. The effects of operating conditions and fluid thermophysical properties on this relation are found to be irrelevant.
THE FRENCH ARTICLE AND ITS CORRESPONDING FUNCTIONAL EQUIVALENTS IN THE KYRGYZ LANGUAGE
Authors:   Bishkek State University named after K.Karasaev, Mambetova Kyzylgul
Published: January 2024

The article deals with the French article system. An attempt has been made to identify if not explicitly expressed explicit functional correspondences of the French article to the Kyrgyz language language units in the form of some lexico-grammatical means, then at least implicitly expressed implicit correspondences. It is shown that the French article has two parallel linguistic conceptual categories: definite-undetermined and wholeness-partiality. It is indicated that the grammatical category of partiality (partitiveness) in Kyrgyz nouns is not traced either in lexemes or even on the scale of the sentence context, because Kyrgyz nouns do not have this conceptual category. Because, firstly, there is no linguistic unit of the article in the Kyrgyz language, and, secondly, from the position of linguistic typology, these conceptual and semantic categories cannot be expressed in any way, as is the case in the French article. On the basis of the presented study, it is concluded that the French article does not have any functional correspondence in the Kyrgyz language.

Published: January 2024

Objectives: To demonstrate the nutritional and functional characteristics of the developed phytochemical containing prebiotic-enriched chocolates. Methods: Methods of Association of Official Analytical Chemists and standard biochemical procedures were employed for the determination of nutrient and phytochemical composition. Antioxidant and prebiotic activity were calculated through DPPH, the reducing potential assay, as well as the growth kinetics and plate count of Lactobacillus rhamnosus GG, respectively (p ≤ 0.01, 95% confidence interval). The functionality of the products was also analyzed in an in vitro simulated human intestinal digestion environment. Findings: Variation 3 (V3) chocolates prepared through the incorporation of cocoa powder (64%), cocoa butter (22.5%), stevia (3%), inulin (10%), and soy lecithin (0.5%), scored the highest sensory rating amongst all the prepared products. V3 revealed a desired proportion of proximate components (low fat and high fibre), minerals, vitamins, and phytochemicals such as polyphenol (25mg/g), alkaloids (189 mg/mL), and flavonoids (46mg/g), versus the standard chocolate (S), along with a low calorific value of the former (541.2Kcal). Furthermore, V3 could efficiently scavenge 2, 2-diphenyl-1-picryl-hydrazyl (86.04±0.4%), display reducing power (2.84±0.02), and accelerate the growth of probiotic Lactobacillus rhamnosus GG (OD 0.59, 11.61 Log CFU/mL at 20 hours), portraying antioxidant and prebiotic properties. Interestingly, V3 was found to sustain a significant proportion of antioxidant and prebiotic potential under imitated intestinal digestion, indicating their effectiveness in propagating benefits in the human body post-consumption. Novelty: Considerable retention of the antioxidant and prebiotic effects post intestinal digestion, besides the nutritional and phytochemical constitution of V3, may promote well-being consequent to its adaption alternative to conventional chocolates.

Authors: Durán Ernesto , González-Cabrera Cristian , Prigge Matthias
Published: January 2024

This protocol covers chronic optrode construction, implantation, and recording in the Locus coeruleus (LC). It begins with building the optrode, involving assembly of a plastic housing, screw, thumbnut, and electrode interface board (EIB-32), followed by attaching electrodes and optic fibers to the EIB-32. The electrodes are then glued and trimmed, ensuring protection from animal-related damage. Implantation involves anesthesia, craniotomy, and careful electrode positioning. A gradual approach is recommended for electrode insertion to minimize tissue damage. The optrode is secured with cement and vaseline for stability. For recording from the LC, an OpenEphys system with omnetics headstage and acquisition software is used. Animals undergo 30-minute sessions with opto-tagging via red or blue light pulses. The setup ensures precise data acquisition and identification of neuron responses.
Subzero temperatures and low-frequency impact on MFC piezoelectric transducers for wireless sensor applications
Authors: Płaczek Marek Łukasz , Kokot Grzegorz , Degefa Tolera G.
Published: January 2024

This research paper is a continuation of a prior study [12] that focused on the positive temperature range. The current work investigates the behavior of a laminated Macro Fiber Composite (MFC) piezoelectric transducer when exposed to negative temperatures. The study aims to understand the sensitivity of the transducer under varying ambient temperatures and frequencies, particularly for applications in wireless sensor networks. The integrated Macro Fiber Composite piezoelectric transducer is both theoretically modeled and empirically verified. Experimental tests involve subjecting the laminated MFC piezoelectric transducer to sinusoidal forces generated by an electro-pulse waveform generator, while a thermal chamber is used for temperature control. Controlled displacement is applied to the transducer at low-frequency (5 to 25 Hz) ranges and different moderate temperatures (0 to -40 degrees Celsius). The results highlight the significant influence of temperature and excitation frequency on the generated voltage by the MFC transducer.

Authors: Rincón Nancy , Galindo Andres , Pérez Jhonny
Published: January 2024

In the organic load removal in a wastewater treatment system, biochemical processes and hydrodynamic aspects take place as characteristicsof the flow, mix regime, residence times and reactor geometry, otherwise, the conditions for non­ideal flow as by­passing, dead zones and internal recirculation affect their performance. This study deals with an evaluation of the hydraulic behavior of a double­chamber anaerobic reactor (DCAR) of 534.5L (chamber 1=305L and chamber 2=229.5L) as a technological innovation of the UASB reactors. The DCAR was fed with Maracaibo, Venezuela municipal wastewater; each chamber was inoculated with agranular, localbrewery sludge (20% v/v). The hydraulic evaluation was performed at the liquid phase and in operation, using Li+ (LiCl) as a tracer applied in an instantaneous way at the affluent at the theoretical hydraulic retention time (TRHt) of 6 hours; 3.4 in the chamber number 1 and 2.6 in chamber number 2. The DCAR described as a plugflow in both chambers and a hydraulic efficiency close to the unit (1), indicating an almost null presence of dead zones. The CDO (CDOT) of DCAR removalefficiency was kept in the range of 59.77% to 74.46% with an average of 68.26%. For chambers 1 and 2 the average efficiency was 60.4 and 20.94 with a biogas production (L/h) of 2.768 and 0.541 respectively.

Authors: Guzmán Luna Jaime Alberto , Torres Pardo Ingrid Durley , Martínez Arlex David
Published: January 2024

This paper presents architecture for Web service composition, in which a plan of composition is constructed based on an agent planning, which can be executed in a concurrent way during its composition in order to estimate the following action to be executed instead of preparing a complete plan which frequently would be invalidated. This feature is invaluable when it comes to addressing problems in real time. Specifically we propose a test domain online games software, called ENVIRO.

Published: January 2024

This paper describes a case based expert system for hypertension diagnosis in Santa Clara city, Cuba, carried out as part of an investigation to know the incidence of the disease in this population.
The studied population’s sample was formed by 455 men and 394 women, with ages between 18 and 78 years. The cases were classified in three groups: normal (people with normal blood pressure), with prehypertension (people that has risk to suffer hypertension) and people with hypertension.
A statistical process was made with this sample in which multivariate techniques as Discriminant Analysis and Logistic Regression were used. The results of these techniques and the application of the Fuller’s Triangle Method were used in the system for ranking the hypertension risk factors and for obtain their importance grade (weigh). CHAID technique allowed reduces the comparisons of the cases making more efficient this process. With the application of the analysis of variance (ANOVA) and TwoStep Cluster Analysis the features comparison function for continuous variables was obtained.
With all this information the likeness function was build to compare the new case with the rest of cases of the case base. The adaptation of the solution of the most similar cases was carried out with the application of nearest k-neighbors algorithm.
Finally the system was validated and was checked an effectiveness of 96%.
Solving the traffic assignment problem using real data for a segment of Medellin’s transportation network
Authors: González Calderón Carlos Alberto , González Calderón Guillermo , Posada Henao John Jairo
Published: January 2024

This paper is based on data obtained from most recent transportation studies done in the Metropolitan Area of Valle de Aburrá, city of Medellín and other 9 municipalities. The studies were based on an Origin/Destination Survey (2005), Analysis of bus routes (2006), and Mobility Master Plan (2006). This paper explains the process of writing a software application for a given network (Network of Medellin) that solves the deterministic user equilibrium problem. The software code was implemented in Visual Basic .NET®,supported by some operations using Microsoft Excel®, and hardcoded for a segment of the Medellin network. The user equilibrium distribution of flow was found by using the Frank-Wolfe algorithm. The applied algorithm was analyzed in some aspects such as number of iterations, convergence patterns, response time, as well as changes in network demand. The traffic assignment models were analyzed by using the algorithm during the P.M. peak hour (hour of highest traffic congestion). The analysis was compared with the resultsfrom the traffic assignment procedure using TransCAD® (well-known and used transportation demand software) for the 2005 database and it was found that the software is somewhat faster than the algorithm, but the latter could be a good tool for practitioners and students for modeling small networks.
Environmental economic dispatch with fuzzy and possibilistic entities
Authors: Muela Edgar , Secue Janneth
Published: January 2024

In this paper a fuzzy possibilistic model for Environmental Economic Dispatch is presented, in order to consider adequately some involved uncertain variables. The developed model can be viewed as an integrative focus where uncertainty is not considered like a simple decision making parameter but it is analyzed as a criterion decision. Here, a fuzzy possibilistic model looks for reflecting the imprecision, ambiguity, and vagueness present in the analyzed problem. Fuzzy sets and possibility theory are an alternative to do this, because they allow including this sort of imperfect information into the problem.
Controller design for a flyback coverter in operating interconnected to grid mode, for photovoltaic applications
Authors: Trujillo Rodriíguez César Leonardo , Díaz Aldana Nelson Leonardo , Hernández Mora Johann Alexander
Published: January 2024

This article presents the modeling of a flyback converter integrated in a two-stage photovoltaic microinverter with grid connection, and the design of the respective controllers. The idea is to obtain the dynamic modeling of the DC / DC converter in order to implement a type of control that allows it to operate as a current source and in turn allows to regulate the input voltage, based on the signal resulting from the location point algorithm. maximum power. This control scheme is novel and has been documented by some authors using boost type converters. Therefore, the great contribution of this article lies in the use of this novel scheme to take advantage of the maximum energy coming from the panels, using a converter that has the characteristic of galvanically isolating the generation from the rest of the circuit. To validate the operation of the flyback under study, simulations were carried out in PSIMTM. Finally, the conclusions are presented.

Authors: Salazar Gómez Antonio José , Cuervo Ramírez Diana Katherine
Published: January 2024

This protocol was carried out with the purpose of having a methodology for the certification of electromagnetic compatibility of medical electrical equipment, in relation to radiated emissions, in accordance with the provisions of the IEC 60601-1-2 and CISPR 11 standards. on telemedicine equipment in an anechoic chamber, with a spectrum analyzer connected to a biconical antenna (20 MHz to 200 MHz) and a log-periodic antenna (200 MHz to 1000 MHz). The distance of the measurements was 3 m, for which the emission limits of disturbances established by CISPR 11 were standardized. The noise levels found in the anechoic chamber were low. The tested equipment presented multiple emissions outside the allowed value. This is the first work in Colombia of radiated emissions from electromedical equipment in an anechoic chamber.
La No Neutralidad en Educación Social: Posicionamiento de las Universidades Públicas Catalanas sobre la Violencia de Género
Authors: Puente Ginés , Carbonell Sara
Published: January 2024

A través de un análisis discursivo mediante la utilización de propuestas propias de la Investigación-Acción-Participación-Feminista y de la Metodología Comunicativa, se analizará la idea de la neutralidad y la no neutralidad en las universidades públicas catalanas, en general, y en los grados de Educación Social y en su relación con la violencia de género, en particular. Se destaca que la supuesta neutralidad en la educación social es ficticia, ya que diversos factores como las creencias y valores del profesorado, el sistema político, las ideologías, los recursos disponibles, el contexto del país influyen en el contenido curricular, la forma en cómo se imparte, cómo los y las estudiantes lo interpretan y en cómo lo aplican a sus vidas. En este sentido, se propone la necesidad de trabajar para ofrecer una variedad de perspectivas y fomentar el pensamiento crítico en el alumnado. Asimismo, se sugiere la importancia de que las acciones y la consciencia vayan cogidas de la mano para revertir la situación y abordar la necesidad de mejorar la formación para prevenir la violencia de género.

Official Statistics and Assessment of the State of the Fight against Crime in 2012–2022
Authors: Maslov V. A.
Published: January 2024

Taking into account enormous importance of reliable initial criminological information for criminal policy, the paper examines the issue of reflecting an objective picture of the fight against crime in official statistics. Using the method of statistical analysis, the author examines: the number of registered crimes in Russia (2012–2022); reported cases of administrative offenses in courts of general jurisdiction (2012–2022); the number of convicts in Russia, the number of individuals with criminal history on record or with an outstanding conviction, their share in © Маслов В. А., 2024

the total number of convicts, the structure and proportion of convicts in the context of committed crimes (2012– 2022); the number and proportion of convicted persons in correctional colonies for adults, depending on the age at the time of the crime, as well as taking into account the repetition of imprisonment (2012–2021); crimes of persons serving their sentences in educational colonies for minors (2012–2021). A number of the studied indicators are presented in the form of diagrams for clarity. Attention is paid to reducing the number of registered crimes while increasing appeals to the internal affairs bodies. The paper highlights as a matter of concern the fact of a consistently high proportion of grave and especially grave crimes in the crime structure, the fact of an increase in both short-term (up to 1 year) and long-term (over 10 years) terms of imprisonment of persons serving sentences in correctional colonies for adults. Attention is focused on the problems of a disproportionate decrease in the number of persons held in educational colonies for minors convicted of rape, an increase in the proportion of minors convicted of murder. In conclusion, the author provides a number of recommendations for the correct work with information relevant to the fight against crime, highlights the most important statistical trends, both positively and negatively characterizing the criminal situation in Russia.
