Les dessins doubles de Maria Bussmann
Authors: Raulin Anne , Bussmann Maria
Published: June 2024

Maria Bussmann est philosophe et plasticienne, et son expression passe par le dessin. Dessins énigmatiques, qualifiés par Hélène Cixous de « charades », ils se révèlent en partie grâce au livre que le philosophe de l’art David Carrier vient de leur consacrer. Cet article cherche à éclairer la double face d’une artiste dont l’oeuvre a été surtout exposée à Vienne (Sécession) et à New York. Il s’attache très précisément à explorer ses dessins qui multiplient les figures de double, où se manifestent oppositions, paradoxes, ententes, renversements.

Published: June 2024

The current study aims to identify the degree of academic freedom practice and its relationship to the added scientific value and mobile technological forecasting from the perspective of faculty members in Saudi universities. To achieve this goal, a random sample of 23 faculty members from King Khalid University was selected from various specializations. A questionnaire was prepared to determine the extent of academic freedom exercised, the scale of scientific value added, and the scale of technological forecasting. The mean, standard deviation, and linear regression analyses were also used to analyze the research results. The results revealed that faculty members’ practice of academic freedom was average, while scientific value added and technological forecasting were high. The results also indicated the potential to predict the exercise of academic freedom through rapid access to information, financial resources, and technological forecasting.

Published: June 2024

In this paper, we investigate the efficacy of an edX-based learning technology and learning environment augmented with artificial intelligence (AI) applications in fostering technological innovation skills among university students. A quasi-experimental design was employed, involving two groups of bachelor’s degree students (n = 57) from the College of Education at King Khalid University. The experimental group (n = 28) utilized the edX platform with integrated AI features, while the control group (n = 29) employed the traditional Blackboard platform. Both groups participated in the “Using Computers in Education” course. A pre-post assessment of technological innovation skills was conducted, and the data were analyzed using an independent sample t-test. Results revealed a statistically significant difference in skill development between the groups, favoring the edX platform with AI integration. These findings suggest that using blended learning environments may have the potential to enhance students’ technological innovation capabilities.

Histoire des premières traductions de la littérature hébraïque moderne en français
Authors: Kaufmann Francine
Published: June 2024

L’histoire de la traduction de la littérature hébraïque moderne en français est encore lacunaire. Il existe pourtant des disciplines et des instruments de recherche qui se sont développés ces dernières décennies et qui permettent de mieux connaître la nature et le volume des échanges culturels entre Israël et la France : répertoires, annuaires, sites internet. La traductologie, la sociologie de la traduction, l’histoire culturelle éclairent d’un jour nouveau ce domaine qui a déjà donné lieu à quelques études approfondies. Cet article est le résultat d’un travail personnel de documentation entamé depuis des décennies et tient compte des nouveaux acquis scientifiques. Il constitue le premier volet d’une étude dont la suite paraîtra dans le prochain numéro de Tsafon, revue d’études juives du Nord (n° 88). Il explique les circonstances qui ont suscité un besoin de traduire en français les sources du judaïsme puis, après l’apparition d’une littérature hébraïque moderne et la naissance du sionisme, une curiosité voire un intérêt du public et de l’édition française pour les œuvres représentatives du patrimoine littéraire de la Palestine juive et de l’État d’Israël.
Madame Bovary et le bovarysme sur la scène littéraire yiddish au début du XXe siècle : de la traduction à l'interprétation culturelle
Authors: Rousselet Cécile
Published: June 2024

Le cas de la réception yiddish de Madame Bovary peut sembler sans grande originalité, au prisme de la quantité d’ouvrages européens alors en circulation en Europe centrale et orientale, qu’il s’agisse d’originaux, de traductions allemandes, russes ou même yiddish, au début du siècle. Et pourtant, Madame Bovary peut difficilement, dans les milieux intellectuels, être reçu sans tenir compte des développements critiques liés à la conceptualisation de l’œuvre flaubertienne sous le nom de bovarysme et de ce que la réception de l’œuvre a pu impliquer pour les développements littéraires sur la scène yiddish au début du XXe siècle. Comment le monde yiddish a-t-il hérité du bovarysme (qu’il soit nommé tel quel ou illustré par les textes littéraires) ? Pourquoi s’est-il particulièrement saisi de l’œuvre flaubertienne au moment même où il opérait un tournant et affirmait une sensibilité moderne en rupture avec des schèmes traditionnels d’écriture ? Par une étude de la réception du modèle d’Emma Bovary dans les milieux littéraires et critiques et une comparaison avec d’autres concepts hérités de la littérature européenne, comme l’oblomovisme, il s’agit de montrer que le passage de la traduction à la conceptualisation du roman flaubertien a encouragé une véritable interprétation culturelle de Madame Bovary en Europe centrale et orientale.

Background/Objectives:

Caring for individuals with psychosis is an emotionally demanding task as caregivers often face significant psychological challenges. The experience and intensity of these challenges might differ across cultural contexts. This study sought to analyze and compare the prevalence and severity of depressive symptoms among caregivers of patients with schizophrenia in Morocco and France.

Methods:

Our retrospective observational study included 130 caregivers from Morocco and 5057 from France. We used the Center for Epidemiological Studies Depression Scale to screen for depressive symptoms and evaluated variations in symptom manifestation using the four-factor model. Furthermore, we evaluated the impact of a family intervention program called Profamille on alleviating these symptoms by examining improvements in caregivers’ mood and patients’ social functioning, using the life skill profile 20.

Results:

Moroccan caregivers displayed a higher prevalence (72%) and severity of depressive symptoms compared to French caregivers (51%). While Moroccan caregivers scored higher in the interpersonal problems subscale, they did not notably differ in the somatic subscale, challenging some preconceived cultural notions. Postpsychoeducational intervention, a significant reduction in depression rates was observed in both Moroccan and French groups.

Conclusions:

Moroccan caregivers, despite the nation’s collectivist culture emphasizing strong familial bonds, exhibited heightened depressive symptoms, hinting at potential culture-specific challenges. Psychoeducational interventions were effective across both cultural groups, indicating their universal therapeutic potential. The findings emphasize the importance of recognizing and addressing cultural variations in caregiving experiences and mental health symptomatology.

Authors: Czornobay Sabrina Ferreira de Lima , Martins Camila Marinelli , Barreto Adalberto de Paula , Pecharki Giovana Daniela , da Silva Milene Zanoni
Published: June 2024

Background/Objectives:

Identify the factors associated with participation in Integrative Community Therapy (ICT) circles in Brazil, focusing on the socio economic profile, health status, usage of other Traditional, Complementary, and Integrative Medicines (TCIM), mental disorders, and support from family and friends.

Methods:

Data from the 2019 National Health Survey of Brazil (NHS) were used, in which, of the 94,114 people interviewed, 5649 answered the question regarding participation in ICT circles, with 93 affirmative answers. A paired case-control study was carried out with measurement of simple and relative frequencies, Pearson's Chi-square test, odds ratio (OR), 95% CI and logistic regression to control confounding variables.

Results:

The profile of participants who most frequently attended ICT circles predominantly included women (38.5%), from urban areas (37.3%), identifying as white (40.1%), residing in the Midwest region (65.2%), and living alone in their household (44.9%). After logistic regression, the variables that remained statistically significant were Auriculotherapy (OR = 7.45), Meditation (OR = 4.78), some ICHP by SUS (OR = 6.65) and being diagnosed with Depression (OR = 2.06).

Conclusions:

As a genuinely Brazilian practice, ICT is aligned with the Principles and Guidelines of the Brazilian Public Health System, thus highlighting the importance of the public sector in ensuring that this and other ICHP are implemented and promoted in the country, since it is a strategy that can guarantee over the years the reception of the population.

The Use of Machine Learning Algorithms in the Simulation of Multi-Layer Acoustic Palliatives
Authors: Harry Evan , Morris-Kirby Rod , Caponio Eleonora , Hoang Minh Tan
Published: June 2024

As palliative acoustic material mixtures and compositions become more complex, the ability to accurately simulate their acoustic performance within an installed NVH component is becoming increasingly difficult. Historically, Biot parameters and their associated TMM models have been used to simulate the acoustic performance of multi-layered material compositions. However, these simulations are not able to account for real-world complexities such as manufacturing imperfections or inter-layer gluing effects. The assumptions made by simulation models, such as the perfectly diffuse field, are rarely true in actual measurements, let alone in the vehicle, further increasing the uncertainty when comparing measurement versus simulation.

There already exists widely accepted methods for obtaining Biot parameters for single-layer materials. Typically, a multi-layer simulation considers each individual layer in isolation rather than its interactions with the rest of the composition after heating, compression, or gluing. The current trend towards sustainability is also adding restrictions to the types of materials that can be used. Target compliance for NVH components includes acoustic parameters and environmental impact, increasing the effort required for component quotation.

This paper examines four possible approaches used to satisfy an OEM’s quotation request which range from flat samples to fully built vehicle systems. It successfully examines the suitability of bespoke machine learning algorithms combined with large measurement and simulation databases.
Gaussian Process Surrogate Models for Vibroacoustic Simulations
Authors: Luegmair Marinus , Dantas Rafaella , Schneider Felix , Müller Gerhard
Published: June 2024

In vehicle Noise Vibration Harshness (NVH) development, vibroacoustic simulations with Finite Element (FE) Models are a common technique. The computational costs for these calculations are steadily rising due to more detailed modelling and higher frequency ranges. At the same time the need for multiple evaluations of the same model with different input parameters – e.g., for uncertainty quantification, optimization, or robustness investigation – is also increasing.

Therefore, it is crucial to reduce the computational costs dramatically in these cases. A common technique is to use surrogate models that replace the computationally intensive FE model to perform repeated evaluations with varying parameters. Several different methods in this area are well established, but with the continuous advancements in the field of machine learning, interesting new methods like the Gaussian Process (GP) regression arises as a promising approach.

In Gaussian Process regression there are important parameters that strongly influence the prediction accuracy of the GP Model, namely length-scale, variance, and mostly the kernel function. In this contribution these parameters and their influence on the results are evaluated, with a focus on vibroacoustic simulations. For the kernel function, four different types – stationary, nonstationary, spectral and deep learning kernel, respectively – are under investigation. As a result, it can be shown that their performance corelate with the data complexity. Further investigations focus on the frequency as input parameters and the influence of the number of training samples.

In these evaluations there is an interesting difference between a simple academic model and a body in white model. The underlying effects, such as damping, system complexity, uncertainty and load case are discussed in detail. Finally, a recommendation using GP as a surrogate model for vibroacoustic simulations is given.
Development of an Evaluation Methodology for PIV Measurements of Low-Frequency Flow Phenomena on the Vehicle Underbody
Authors: Breitenbücher Laura , Wagner Andreas , Wiegand Thomas , Brink Maarten , Buderer Bastian
Published: June 2024

Aeroacoustics is important in the automotive industry, as it significantly influences driving comfort. Particularly in the case of battery electric vehicles (BEVs), the flow noise is already crucial at lower driving speeds, because they generate barely any drive noise. In addition, the masking effects from engine noise are missing. Due to the increasing importance of drag minimization and elimination of the exhaust system, the underbody of BEVs is typically very streamlined and exhibits a low acoustic interference potential. However, even small geometric modifications of the vehicle can lead to changes in the flow around the vehicle and consequently to significant noise sources. Considerable flow resonances in the low frequency range below 30 Hz have been detected on certain prototype configurations. Initial investigations have shown that the flow around the front wheel spoilers is relevant for the development of the flow phenomenon. Nevertheless, the exact and complex mechanism of formation of the low-frequency flow resonances is still largely unknown. The aim of the study is to identify their exact origin. Particle Image Velocimetry (PIV) measurements were carried out in the wind tunnel. The flow field was measured in a plane parallel to and below the vehicle underbody. Acoustic quantities were measured using surface microphones. An evaluation method was developed in order to investigate the cause of the low-frequency pressure fluctuations in detail. The evaluation method developed is presented in this paper. The results are then described and discussed. Using these results, the origin of the low-frequency flow resonances is finally explained.
Using the Irrotational Intensity Field to Study Vibration Energy Paths in Automotive Structures
Authors: Gagliardini Laurent , Takhchi Jamal , Sadoulet-reboul Emeline , Ouisse Morvan , Bornet Frederic
Published: June 2024

Although structural intensity was introduced in the 80’s, this concept never found practical applications, neither for numerical nor experimental approaches. Quickly, it has been pointed out that only the irrotational component of the intensity offers an easy interpretation of the dynamic behavior of structures by visualizing the vibration energy flow. This is especially valuable at mid and high frequency where the structure response understanding can be challenging. A new methodology is proposed in order to extract this irrotational intensity field from the Finite Element Model of assembled structures such as Bodies In White. This methodology is hybrid in the sense that it employs two distinct solvers: a dynamic solver to compute the structural dynamic response and a thermal solver to address a diffusion equation analogous to the thermal conduction built from the previous dynamic response. The field separation is based on the Helmholtz-Hodge theorem, which ensures the computation’s full consistency. The methodology is first implemented and validated in the case of a plate assembly, using commercial FE software. This first approach immediately highlights a bias in the current power flow computations, leading to erroneous transmission path understanding. It also shows a remarkable stability of the irrotational intensity patterns regarding frequency. As one would expect, transmission path only makes sense when they stand for a broad enough frequency range. The methodology is then applied to an automotive structure, introducing specific modeling of the mechanical connections between stamped steel parts (spot welds, bolts, bids…). Again the method applies well and shows fully consistent results.
A New Equivalent Static Load (ESL) Creation Procedure for Complete Vehicle
Authors: Weber Jens , Luiz Felipe Faria Ricardo , Bäcklund Jesper , Vignati Michele , Cheli Federico
Published: June 2024

When dealing with the structural behavior of a car body, analyzing the dynamic distortion in all body closure openings in a complete vehicle, provides a better understanding of the body characteristics compared to traditional static load cases such as static torsional body stiffness. This is particularly relevant for non-traditional vehicle layouts and electric vehicle architectures where mass distribution and in particular battery mass and stiffness play a completely different effect with respect to the internal combustion engine vehicles.

A methodology typically adopted to measure the body response, e.g. when driving a vehicle on a rough pavé road, is the so-called Multi Stethoscope (MSS). The MSS is measuring the distortion in each body closure opening in two diagonals. During the virtual development, the distortion is described by the relative displacement in diagonal direction in time domain using a modal transient analysis. The results are shown as Opening Distortion Fingerprint ODF and used as assessment criteria within Solidity and Perceived Quality.

By applying the Principal Component Analysis (PCA) on the time history of the distortion, a Dominant Distortion Pattern (DDP) can be identified. The DDP means that, for a given pavé time history, more than 50 % of the body deformation states are similar to each other. This paper presents a deeper analysis about the forces which are associated with this Dominant Distortion Pattern (DDP). The new aspect of this analysis is that all forces (54 in total) between the wheel suspension and the trimmed body are considered. Based on the results of this force analysis, a new procedure for creating an Equivalent Static Load (ESL) was developed. Finally, by automating this creation procedure it is shown how the new ESL can be integrated in the virtual vehicle development.
Efficient Engine Encapsulation Strategy Using Poroelastic Finite Element Simulation

Published: June 2024

With the increasing importance of electrified powertrains, electric motors and gear boxes become an important Noise Vibration & Harshness (NVH) source especially regarding whining noises in the high frequency range. Engine encapsulation noise treatments become often necessary and present some implementation, modeling as well as optimization issues due to complex environments with contact uncertainties, pass-throughs and critical uncovered areas.

Relying purely on mass spring systems is often a too massive and relatively unefficient solution whenever the uncovered areas are dominant. Coverage is key and often a combination of hybrid backfoamed porous stiff shells with integral foams for highly complex shapes offer an optimized trade-off between acoustic performance, weight and costs. A dedicated experimental set-up has been designed in order to measure both structureborne and airborne NVH performances of engine encapsulation insulators applied on an engine casing placed in a coupled reverberant / semi-anechoïc rooms suite.

Experimental measurements, including airborne and structureborne Insertion Losses have been performed on a mocked-up test set-up with and without leakages and have been compared to a fast flat and curved Transfer Matrix Method as well as an accurate poroelastic finite element model including maximum treatment mock-ups. A good correlation between simulation and measurements has been observed and the difficulties of this modeling task are pinpointed. Uncovered areas as well as tuckers radiation issues will be highlighted both experimentally and numerically and improvement potentials will be shown as well.

Catalysts under Real Engine Conditions

Published: June 2024

Fossil fuels such as natural gas used in engines still play an important role worldwide which however is also exacerbating climate change as a result of carbon dioxide emissions. Although natural gas engines show an overall low pollutant emissions level, methane slip due to incomplete combustion occurs, causing methane emissions with a more than 20 times higher global warming potential than CO2. Additionally, further tightening of emissions legislation is to be expected bringing methane emissions even more into focus making exhaust gas aftertreatment issues remain relevant. For lean gas applications, (Pd)-based catalysts turned out to convert CH4 most efficiently usually being supported by metal oxides such as aluminium oxide (Al2O3). Water (H2O) contained in the exhaust gas causes strong inhibition on Pd catalysts. In real exhaust gases, not only water vapour but also pollutants and sulphur-containing compounds such as hydrogen sulphide (H2S) or sulphur oxides (SOx) are poisoning the catalytic converter. Rich pulses decomposing sulphur species adsorbed on Pd-Pt methane oxidation catalysts, enable efficient regeneration of heavily poisoned catalysts. A strategy similar to operation with rich pulses, but with a different motivation, is the use of high-frequency oscillations between lean and rich exhaust gas, so-called dithering, to improve pollutant conversion. A combination of a stoichiometric pulse while simultaneously dithering shows better results in recovery as well as emissions during regeneration than a pure rich pulse.
Definition of a Rule-Based Energy Management Controller for the Simulation of a Plug-In Hybrid Vehicle Using Power and On-Board Measured Data

Published: June 2024

Vehicle powertrain electrification is considered one of the main measures adopted by vehicle manufacturers to achieve the CO2 emissions targets. Although the development of vehicles with hybrid and plug-in hybrid powertrains is based on existing platforms, the complexity of the system is significantly increased. As a result, the demand for testing during the development and calibration stages is getting significantly higher. To compensate that, high-fidelity simulation models are used as a cost-effective solution. This paper aims to present the methodology followed for the development of a rule-based energy management controller for a plug-in hybrid electric vehicle (PHEV), and to describe the experimental campaign that provided the necessary input data. The controller is implemented in a vehicle simulation model that is parametrized to replicate the real operation of the vehicle. Using such a model it is possible to carry out virtual tests, aiming towards energy management optimization and efficiency improvement. The main target of the experimental campaign and the data analysis was to define the operational and energy management strategy of the vehicle using a back engineering approach. Laboratory tests were performed under legislated cycles and real-world driving profiles. In addition to the standard fuel consumption and emissions measurements, a power analyzer was implemented for the measurement of the currents and voltages, which were then used for the electric power calculation of the main powertrain components (electric machine and high voltage battery). This calculation allowed the evaluation of the power flow within the powertrain and the individual components. In addition, on-board data, such as battery state of charge, engine torque and total fuel and energy consumption (provided by the on-board fuel consumption monitoring measurement -OBFCM- system) were recorded from the on-board diagnostic (OBD) port. All the recorded data and the observations made during the experimental campaign were used to define the appropriate rules for the developed controller.
R290 HP-Module for Electric Vehicles
Authors: Pogorelov Alexej , Reimers Thorsten
Published: June 2024

Within this work a compact automotive heat pump module prototype with the natural refrigerant R290 (propane) is presented. R290 is non-toxic, has a low global warming potential (GWP) of 3, is environmentally friendly and is not affected by PFAS restrictions. Furthermore, R290 has a superior efficiency compared to refrigerants like R1234yf & R134a, which makes it a promising alternative. A test setup is built to evaluate the performance of the prototype HP-module, which is charged with approx. 190g of refrigerant and reaches a cooling/heating capacity of approx. 11kW/16kW at the investigated conditions. In addition, a 1-D numerical tool for the calculation of steady state conditions is implemented in MATLAB/Simscape and validated by time-averaged test data. The objective of the numerical tool is to be able to quickly predict the pressure levels within the refrigerant loop in advance to testing, as the pressure levels of the HP-module are not directly controlled, but result from the operating conditions (i.e., eCC speed, eXV position, coolant loop volume flow rates and inlet temperatures).
FUNDAMENTAL CRITERIA FOR DETERMINING THE RISK OF CONFUSION REGARDING THE PRODUCT ORIGIN IN TRADEMARK LAW

Published: June 2024

The risk of confusion regarding the product’s origin is one of the fundamental concepts of trademark law because marking the origin is the original function of the trademark. „To ascertain this substitution, the criteria outlined in Article 10 of Directive No. 89/104 are employed, which then were developed in court practice. By looking at all the criteria and their mutual relationship, we can conclude that there is a danger of confusion regarding the origin. At the same time, the lower intensity of one can be compensated by the higher intensity of the other. Thus, a low degree of similarity of marks can be compensated by a high degree of similarity of products and vice versa.

Perusahaan telah memiliki data laporan terkait pencapaian pendapatan perusahaan, tetapi informasi dari data tersebut tidak digunakan dengan semestinya. Oleh karena itu penelitian ini bertujuan untuk mengetahui penerapan data mining untuk memprediksi pendapatan perusahaan. Metode penelitian yang digunakan adalah metode DES dan TES, yang memproses sekumpulan data pendapatan yang belum diolah dan belum dikembangkan untuk menciptakan informasi baru yang bernilai dan berguna bagi perusahaan, khususnya untuk perolehan pendapatan perusahaan. Hasil penelitian menunjukan perhitungan MAPE metode DES memperoleh MAPE 98,5 sedangkan metode TES memperoleh MAPE 5,42. Dengan perolehan MAPE yang lebih kecil metode TES lebih relevan dalam penelitian ini di bandingkan dengan metode DES, karena metode TES mempunyai tren dan musiman sehingga lebih akurat dalam perhitungannya di bandingkan dengan metode DES yang hanya mempunyai tren. Dari hasil perolehan MAPE tersebut, penggunaan metode TES dengan perolehan MAPE 5,42. Berdasarkan kriteria MAPE, maka kemampuan untuk memprediksikannya adalah sangat baik.

PERSONAL QUALITIES IMPORTANT FOR THE PROFESSIONAL ACTIVITY OF THE MODERN MIDDLE LEVEL MANAGER
Authors: Khachatryan Ani
Published: June 2024

The peculiarity of this level of management lies in the fact that the middle level manager is the organizer and supervisor of the process of implementation of decisions and actions taken by high-level managers. The modern management system, along with rapid changes in socio-economic conditions, also makes special demands on the middle level manager. In the conditions of modern imperatives, the focus of attention is on the issue of matching the characteristics of managerial activity and the psychological qualities of the manager, which can be the basis for effective activity and professional development. The professional development of middle-level managers is determined by a unique combination of important professional psychological qualities, namely: emotional intelligence, thinking, voluntary self-regulation, social-communication knowledge. The conducted research works provide an opportunity to state that conscientiousness, self-regulation of behavior, and creativity are important personal qualities for a modern middle level manager. Creativity is also characteristic of middle level managers: it is above average among middle level managers. It means that we can talk about such important professional qualities of a modern middle level manager as conscientiousness, control of behavior and creativity.
ПРОФЕССИОНАЛЬНАЯ ИДЕНТИЧНОСТЬ СТУДЕНТА В КОНТЕКСТЕ ПРОФЕССИОНАЛИЗАЦИИ

Published: June 2024

Рассматривается возможность использования знака-символа ψ в работе со студентами-психологами с точки зрения их приобщения к профессии. Затрагивается вопрос профессионализации студента, предлагается особое внимание обратить на один из основных “компонентов” профессионализации - профессиональную идентичность (ПИ). Говорится о возможноси формирования ПИ в рамках общеобразовательной педагогической технологии, подчеркивается важность разработки и внедрения новаторских идей, задающих позитивный вектор развития ПИ у студента-психолога. Приводится “доказательная база” потенциальной возможности развивающего психологического воздействия профессионального символа ψ на студента-психолога. Анализируются теоретические взгляды исследователей на значение символов и знаков для человека в контексте их воздействия на психику. Обосновывается логичность использования термина знак-символ в отношении ψ, демонстрируется возможность перехода знака в символ и символа в знак в восприятии студента в зависимости от его чувства сопричастности к профессии. Выявляется связь на теоретическом уровне ПИ с таким психологическим феноменом, как “личностный смысл”.Проведено исследование со студентами-психологами. В качестве основного метода исследования используется метод структурированного интервью, а также метод беседы. Цель исследования заключалась в выяснении влияния процесса создания студентами собственного символа ψ на их отношение к ψ в контексте формирования чувства сопричастности к профессии. Были представлены тематические задачи, решение которых позволило сделать определенные выводы. Показано, что процесс создания символа ψ способствует появлению чувства сопричастности к психологии у студентов-психологов. Отмечается, что творческий процесс создания собственного ψ способствует формиророванию чувства удовлетворенности у студентов-психологов. Подтверждается влияние символа ψ на формирование ПИ: выявлена ведущая тенденция у студентов определять значимость ψ для психолога как “идентификационную” и “идейную”. Символ ψ рассматривается в роли “катализатора” при запуске процесса формирования ПИ у студента-психолога.Предлагается использовать символ психологии – ψ в поэтапной работе со студентами-психологами на начальном этапе их обучения для приобщения к профессии, повышения эффективности процесса профессионализации.

The rapid urbanization and the scarcity of residential space in metropolitan areas necessitate the construction of tall structures to meet the growing accommodation demands. This research paper focuses mainly on the structural act of high-rise structures under lateral loads, especially earthquake forces. Three lateral load resisting systems, namely outrigger system, shear wall at core and shear wall at corner are compared and analysed. The study reviews relevant literature, discussing parameters affecting the fundamental time period of structural models and the effectiveness of distributed belt wall systems. The research methodology involves the analysis of a 40-storey regular office building using three different lateral load resisting systems. The results obtained through response spectrum analysis, shows that the outrigger system exhibits efficient structural capability in tall buildings. The maximum lateral displacement is significantly reduced in the outrigger system compared to core shear-wall and corner-shear wall. The study concludes that enhancing lateral load resistance and providing a transition path to perimeter columns subjected to lateral load, as seen in the outrigger-system, proves effective in mitigating the impact of earthquake loads on high-rise buildings.
