Intravesical drug delivery (IDD) refers to the administration of therapeutic agents directly into the urinary bladder through a catheter. Low permeability of the urinary bladder epithelium, poor retention of the therapeutic agents due to dilution and periodic urine voiding as well as frequent catheterizations (with potential risk of infections) are the major limitations of IDD used in the treatment of bladder-related disorders, such as bladder cancer. In this work, the mucoadhesive properties of polymeric materials based on chitosan, chitosan-gellan gum, and chitosan-Carbopol™ 940 containing sodium fluorescein (NaFI) were investigated for their potential application in intravesical drug delivery. The evaluation of mucoadhesive properties was carried out using an in vitro flow-through method with fluorescent detection that simulates the interaction conditions of polymers with the urinary bladder mucosa. Additionally, the release kinetics of NaFI from polymer compositions under conditions mimicking the physiological environment of the bladder was studied using a fluorescence spectrometry. The acquired data confirm the promise of using chitosan-based mucoadhesive polymers in developing systems for intravesical drug delivery, which could significantly enhance the efficacy of IDD therapy to treat urinary bladder-related disorders.

Published: November 2024

The synthesis of biologically active compounds frequently requires the establishment of specific conditions (such as pressure, temperature, medium, solvent, and catalyst) or the use of expensive equipment. An important task is the search for simple synthesis methods for promising biologically active compounds. This paper presents data on a rapid method for the synthesis of ald(ket)azines (azines) with a variety of biological and physicochemical properties. Hydrazine hydrate reacts readily by condensation with aromatic (heterocyclic) aldehydes or ketones to form azines. The reaction occurs at room temperature in acetic acid. The synthesis is completed in a short period of time, between 5 and 15 seconds, with yields of 32 % to 98 % after recrystallization. The formation rate of ald(ket)azines depends on the reaction medium and the presence of hydrogen donors in the system, and increases with increasing acidity. The investigation did not yield any discernible pattern in the impact of electron-donor or electron-acceptor substituents in the para-, meta-, or ortho-positions at aromatic (heterocyclic) aldehydes or ketones on the azines yield. The synthesized compounds were studied using 1H NMR spectroscopy, chromato-spectrometry, and elemental analysis. The Ferric Reducing Antioxidant Power (FRAP) spectrophotometric method was used to study the antioxidant activity of the compounds obtained. Compounds with an N,N-dimethyl- or N,N-diethyl group in the para-position of the aldehyde fragment of azine showed a significant antioxidant effect. The results obtained exceed the antioxidant value of ascorbic acid — an industrially used oxidation inhibitor.
Effect of Acetylene Properties on its Gas Sensing by NiO Doped ZnO Clusters: A Transition State Theory Model
Authors: Abdulsattar Mudar A.
Published: November 2024

The sensitivity of nickel oxide doped zinc oxide to industrial gas acetylene was calculated and compared to available experimental data. The adsorption of C2H2 on the NiO-doped ZnO surface and the activation transition states formed afterward were studied computationally. B3LYP version of density functional theory with 6-311G** basis set, including dispersion correction (GD3BJ) was performed for the calculations with the help of Gaussian 09 software. Thermodynamic quantities of the reaction of C2H2 with NiO-doped ZnO surfaces, such as Gibbs free energy, enthalpy, and entropy, were used to interpret the reaction at the temperature range 25–325 °C. Response and response time variation with different NiO doping percentages were calculated. The calculations took into account the combustion of acetylene as it approached its autoignition temperature, which was not considered in previous works. The results show that the optimum response operating temperature of the C2H2 gas sensor is below the autoignition temperature of acetylene at 300 °C. A good agreement of theoretical response and response time with variation of temperature and acetylene concentration was obtained with the experiment. This study was the first to take into account the autoignition of C2H2 in gas sensor calculations and noted that gases can be easily distinguished by their autoignition temperature.

Pododermatitis lesions, also known as “foot calluses”, cause pain and discomfort, alter behavior and walking patterns, and can increase aggression among birds, thus compromising animal welfare. The disease also compromises bird performance, as it commonly results in a worsening of feed conversion and an increase in carcass condemnation. Other obstacles include failure to meet the consumer market for chicken feet, especially in Asia, and possible penalties in animal welfare audits. Numerous factors predispose the emergence of this lesion, such as environmental quality, management, litter quality and humidity, as well as the presence of ammonia (NH3). The present study evaluated the probiotic efficiency based on Bacillus subtilis and Bacillus licheniformis, GalliPro® MS, in reducing broilers' incidence of pododermatitis (foot calluses). Chickens that received diets supplemented with GalliPro® MS had more intact paws, probably because the levels of NH3 and Nitrogen (N) in the litter were lower, ensuring a favorable microenvironment and maintaining the integrity of the paws.
Pneumonia aspirativa em cão

Published: November 2024

Aspiration pneumonia is a pathology resulting from the inhalation of liquid or solid contents via the airways, which leads to inflammation in the lung parenchyma. The course of the disease varies according to the amount and type of material aspirated, as well as the animal's general state of health. The symptoms of the disease are usually acute and severe. In this sense, the drug therapy chosen for treatment depends on the degree to which the lung is compromised and the clinical signs. The surgical procedure of total or partial lobectomy can be advantageous when the lung lesions are irreversible and clinical therapy has been unsuccessful. The aim of this paper is to report the case of aspiration pneumonia in a female Labrador retriever who presented pulmonary crackles after drowning and was given a pulmonary lobectomy. Computed tomography was used to confirm the diagnosis of aspiration pneumonia. This highlights the importance of carrying out complementary tests in order to offer the animal a better therapeutic approach.

Published: November 2024

OBJECTIVE

Shunt infections are costly and stressful for families, patients, and providers. Many institutions use shunt checklists in an effort to reduce the risk of infection following shunt surgery. Such protocols often aim to limit operating room (OR) foot traffic, but there is little evidence that supports the theory that greater OR traffic increases the risk of acquiring a shunt infection through contamination of the air. The purpose of this study was to quantify foot traffic during shunt surgery at a children’s hospital during a time period when a shunt checklist was used.

METHODS

Starting in 2019, a premedical student was tasked with covertly collecting data on 50 shunt operations. Data were recorded in real time and documented in a prospectively updated database. Recording foot traffic through the OR door began at onset of skin prep; data points included patient and surgical details, operative length, and who entered the room and why. Each operation was followed for a minimum of 180 days for infection. The primary outcome was "door event," defined as any time a door to the OR was opened—fully or partially—with or without someone breaking the plane of the door (i.e., entering or exiting).

RESULTS

Fifty operations were observed with no primary shunt infection (mean follow-up 29.8 months, range 6.5–63.3 months). One patient experienced a late secondary infection due to systemic post–COVID-19 inflammatory syndrome causing gastrointestinal bacterial translocation. The average operative time—from applying sterile skin prep until surgery stop time—was 69.8 minutes. Overall, there were 1012 door openings with 1088 personnel entering or exiting. The average number of door openings per operation was 20.24. OR personnel (42.7%) and neurosurgery staff (31.6%) were responsible for the largest number of door events, followed by the anesthesiology service (18.9%). The most cited reasons for door events were for supplies (31.2%) and scrubbing in (26.5%).

CONCLUSIONS

This study represents the first detailed analysis of OR traffic during pediatric shunt surgery. No patient developed a primary shunt infection. While minimizing OR traffic makes intuitive sense, it remains unknown whether a causal relationship exists. Further investigation is needed.
A rare case of posttraumatic subdural hematoma and intratumoral hemorrhage in a left frontotemporal meningioma: a conservative approach with longitudinal follow-up. Illustrative case
Authors: Khaleel Mansour , Sayyed Ahmad Dana , Ayyad Mohammed , Abu Al Ragheb Amer
Published: November 2024

BACKGROUND

Meningiomas are common primary intracranial tumors, with associated intratumoral hemorrhage being a rare but serious complication requiring prompt diagnosis for optimal outcomes. Although spontaneous bleeding in benign meningiomas is rare, it can lead to subarachnoid hemorrhage, subdural hematoma, or intratumoral/intracerebral hemorrhage, significantly increasing morbidity and mortality. Advanced imaging and recognition of radiographic hemorrhage patterns are crucial for accurate diagnosis. Treatment is case specific, as surgical intervention is preferred for symptomatic patients, while observation might be adequate for asymptomatic cases. When surgery is not feasible, stereotactic radiotherapy or chemotherapy, which is used only as salvage therapy, is considered.

OBSERVATIONS

The authors present the case of a 78-year-old male with a history of recurrent falls. Imaging studies revealed a posttraumatic subdural hematoma and an intratumoral hemorrhage within a left frontotemporal meningioma. The patient was managed conservatively, showing significant improvement over 6 months. Notably, there was a marked reduction in both tumor size and intratumoral hemorrhage during follow-up.

LESSONS

This case highlights the importance of adopting case-specific management strategies for hemorrhagic complications associated with meningiomas. While surgery is crucial for symptomatic meningiomas, this case demonstrates that conservative methods can be effective for a subset of symptomatic patients with stable clinical conditions and manageable intracranial bleeding.

Published: November 2024

The Motu Melanesians have since ancient times played a significant role in the economic life of many Papuan and Melanesian societies in the coastal regions of the southeast of the New Guinea island. From the late nineteenth century onward, Motu villages experienced considerable influence of colonial administrations. Subsequently, following Papua New Guinea’s independence in 1975, the impact of globalization intensified, causing significant cultural transformation. To date, however, the Motu continue to maintain their strong cultural identity.
Sub-GHz Broadband Multi-channel Waveguiding Based on Subwavelength Wire Media
Authors: Khobzei Mykola
Published: November 2024

The paper involves the development of a new type of image transfer. With this aim the multi-channel waveguide was considered in a novel representation – it was based on a wire media structure where each space between each four the closest wires is a single subchannel. The utilized wire media (WM) structure has 10-by-10 wires dimensions and 150 mm of the length, thus the first Fabry-Perot resonance appears around 0.9-1 GHz. The goal is to show the broadband multi-channel imaging at frequencies lower than the first Fabry-Perot resonance that means the considered structure tends to electrically short size that has not been studied previously. Taking into account the multi-channel principle of the wire media, the imaging can be performed as a binary one. For this reason, each single channel is fed by individual electromagnetic (EM) source that is a dipole antenna in the non-resonant mode. The reason is to use a weak source and match it with a single channel because in the other case the dipole is perfectly matched at the defined resonance frequency. It was found in the paper that the broadband transfer is possible in the frequency range-under-study and impossible at the region of the first Fabry-Perot resonance due to the perfect complex interaction between all wires of structure. As evidence, a simultaneous transfer of EM power from several independent EM sources shaped as R-letter was performed in the frequency range from 0.3 to 0.75 GHz by simulations and experimental investigations. The clear recovery of the transferred letter is possible in the case when it performs not at the frequency of Fabry-Perot and for the enough value of signal-to-noise ratio (SNR). The binary recovery of the transferred image became possible in the paper with an additional post-image processing with a threshold method involvement.
Classification of Art Objects in the Context of Interior Space Design
Authors: Pylypchuk Oksana
Published: November 2024

The aim of the article is to establish the main categories for classifying art objects with the definition and study of their characteristics regarding the visual and functional impact on the design of interior space, taking into account both traditional and modern trends. Research methods include comparative analysis, field survey, description, systematization and generalization, as well as the results of many years of creative project practice. The scientific novelty lies in the proposed classification of art objects to create a coherent system in terms of its use in the design of interior space. The results of the research are based on the analysis of examples of modern art and project practice. Conclusions. In the process of research, a classification of art objects was created according to six basic categories, which allow tracking the peculiarities of the functioning of a certain art object in the interior. The first of the categories considered the distinction by types of art, according to which it was determined that in relation to traditional types of art, the art object functions, complementing the general artistic concept of the interior, establishing a figurative connection with its space; instead, correlated with modern forms of art, the art object acquires features and a way of functioning of non-traditional arts with modern means of expression, technologies and materials. The second category of division is by function: the predominance of the utilitarian function in an art object allows its introduction as a constructive element of the interior or equipment; while the predominance of the aesthetic function can state the decorative use of the art object. The third category of dividing art objects is by size: large-sized art objects are designed for perception in a sufficiently large space from a long distance; small-sized art objects are designed for perception from a close distance in smaller rooms. The fourth category is based on the form of expression: the realistic form is based on images that correspond to nature and gives the interior space a traditional character; instead, the abstract form with the use of non-realistic means of expression endows the interior space with features of modernity and uncertain content. The fifth category of division is by style: accordingly, the modern style of art objects involves involvement in various currents and directions of modern art, and the means of expression change the traditional appearance of space and its filling; instead, traditional stylistics uses classical forms and means of expression characteristic of known historical trends. The sixth category of division is based on materials: art objects with the use of traditional materials reveal the specificity and structure corresponding to nature, and in the visual perception of the interior space, they give it comprehensibility, basicity and reliability; instead, modern materials allow you to create new forms in the interior space with the help of art objects.

Heat-killed Lactiplantibacillus plantarum N1487-7 induces IL-10 production and enhances skin barrier function
Authors: Uehara Eriko , Hokazono Hideki
Published: November 2024

Background: Interleukin (IL)-10, an anti-inflammatory cytokine, suppresses the release of inflammatory cytokines, such as IL-6, and inhibits the decline in skin barrier function. Mice orally administered test substances by gavage are subjected to physical stress, which results in the secretion of stress hormones. Stress hormones cause inflammation and reduce skin barrier function.
Objective: The effects of heat-killed Lactiplantibacillus (Lpb.) plantarum N1487-7 (N1487-7-HK) on IL-10 production in Caco-2 cells and macrophages, and skin barrier function in physically stressed mice was investigated.
Methods: Lpb. plantarum N1487-7 was cultured in fermented barley extract medium at 30 °C for 22 h with shaking (100 rpm). The washed cells were killed by heating at 110 °C for 10 minutes. The cells were then dried in a centrifugal evaporator and ground to obtain the cell powder. The powder was administered to Caco-2 cells and macrophages, and IL-10 mRNA and IL-10 protein expressions were measured by real-time quantitative polymerase chain reaction and Western blotting, respectively. N1487-7-HK cells or distilled water were orally administered daily by gavage to Hos:HR-1 mice for 5 weeks (the N1487-7-HK group or the control group). During weeks 3 and 5 only, dextran sulfate sodium (DSS) was mixed into the drinking water of these groups to induce mild colitis. The normal group was not orally administered anything by gavage and was not given DSS. Serum IL-10 and the trans epidermal water loss (TEWL) of mice were measured.
Results: N1487-7-HK promoted the expression of IL-10 mRNA and IL-10 protein in both Caco-2 cells and macrophages. In mice subjected to physical stress, serum IL-10 levels in the N1487-7-HK group were significantly increased compared to the control group. The transepidermal water loss (TEWL) in the control group was notably higher than that in the normal group during Weeks 1 and 2. In contrast, the N1487-7-HK group showed no significant difference in TEWL compared to the normal group. The N1487-7-HK group showed a significantly lower TEWL at Week 4 compared to Week 0.
Conclusions: N1487-7-HK promoted IL-10 production from intestinal epithelial cells and macrophages. Intake of N1487-7-HK inhibited the decline in skin barrier function in mice subjected to physical stress.

Trust but Verify: Programmatic VLM Evaluation in the Wild
Authors: Prabhu Viraj , Purushwalkam Senthil , Yan An , Xiong Caiming , Xu Ran
Published: November 2024

Vision-Language Models (VLMs) often generate plausible but incorrect responses to visual queries. However, reliably quantifying the effect of such hallucinations in free-form responses to open-ended queries is challenging as it requires visually verifying each claim within the response. We propose Programmatic VLM Evaluation (PROVE), a new benchmarking paradigm for evaluating VLM responses to open-ended queries. To construct PROVE, we provide a large language model (LLM) with a high-fidelity scene-graph representation constructed from a hyper-detailed image caption, and prompt it to generate diverse question-answer (QA) pairs, as well as programs that can be executed over the scene graph object to _verify_ each QA pair. We thus construct a benchmark of 10.5k challenging but visually grounded QA pairs. Next, to evaluate free-form model responses to queries in PROVE, we propose a _programmatic_ evaluation strategy that measures both the helpfulness and truthfulness of a response within a unified scene graph-based framework. We benchmark the helpfulness-truthfulness trade-offs of a range of VLMs on PROVE, finding that very few are in-fact able to achieve a good balance between the two.

Since Apple’s 2010 release of the revolutionary iPhone 4, the brand has become a dominant force in the tech industry, fostering high customer loyalty through its integrated, secure ecosystem. This study aims to explore the factors driving Apple’s consumer loyalty in Malaysia, focusing on brand experience, brand innovativeness, social influence, perceived value, and brand trust. Primary and secondary data were collected, and a digital survey of 150 Malaysian Apple users provided insights into their loyalty determinants. Using regression analysis, the findings reveal that perceived value and brand trust significantly and positively impact consumer loyalty, while brand experience, brand innovativeness, and social influence show minimal influence. With an R-squared value of 0.596, the model suggests that nearly 60% of loyalty variance is explained by these factors, highlighting perceived value and trust as critical components. These results imply that Apple should prioritize enhancing perceived value and maintaining brand trust to strengthen consumer loyalty in competitive markets. Future research could explore additional factors like sustainability and community engagement to provide a fuller understanding of loyalty drivers in the tech industry

Using organizational commitment as a mediating variable, this study looks at how transformational leadership and organizational culture affect worker performance at the Ministry of Law and Human Rights' Bali Regional Office. Utilizing SEM-PLS 3.0 for data analysis, the study included 169 employees with a sample size of 168. The findings indicated that organizational culture had a positive and significant impact on employee performance, while transformational leadership had no discernible effect. Furthermore, organizational culture and transformational leadership both improved organizational commitment, which in turn improved performance. The impact of organizational culture on employee performance was partially mediated by organizational commitment, while the effect of transformational leadership was fully mediated by it. These results suggest that since a positive organizational culture directly improves performance, enhancing it may be necessary to improve employee performance at the Bali Regional Office. Despite not having a direct impact on performance, transformational leadership is essential for increasing organizational commitment, which eventually improves worker performance. Therefore, initiatives to improve commitment and culture may be important tactics for improving employee results

Published: November 2024

Introduction. At present, automatic capture and tracking of moving objects in video data obtained by a video camera mounted on a mobile carrier represents a relevant research task. Its successful solution is challenged by such factors, as a non-uniform background, object overlapping between one another and the background, significant and rapid changes in the size of the object of interest, abrupt changes in the movement trajectory of the mobile carrier.

Aim. To develop an automatic method for detecting moving objects followed by their tracking in video data obtained under difficult observation conditions. An additional requirement imposed on the tracking stage consists in the restriction of computing resources.

Materials and methods. The method is based on a convolutional neural network with a YOLO architecture. Due to the restriction of computing resources, object tracking is implemented without neural network solutions. In order to ensure stable tracking, several detectors are used simultaneously with the subsequent analysis of the data obtained. The tracking stage involves a detector based on histograms of oriented gradients (HOG), supplemented by a detector based on correlation filtering and motion trajectory prediction based on the Kalman filter.

Results. At the automatic detection stage, the TPR, averaged over all video files participating in the experiments, was equal to 0.81, with the FPR corresponding to 0.10. At the tracking stage, the failure rate (tracking failures) was 6·10 –5.

Conclusion. The proposed method can be successfully used to detect and track objects at a distance of 1500 m with an object projection size on the frame of 5 × 5 pixels under the conditions of global motion, a non-uniform background, and significant changes in the properties of the object of interest.
Mutual Synchronization of Spintronic Nano-Oscillator Ensembles
Authors: Tsyrulnikova L. A. , Frolov D. A. , Safin A. R.
Published: November 2024

Introduction. The use of spintronic components significantly enhances the performance, reduces the size, and lowers the power consumption of modern electronic devices. The spintronic oscillator (SO) is an integral part of spintronic devices. Connecting several SOs (> 100) into ensembles with subsequent synchronization mitigates such SO drawbacks as low output power and high phase noise. These drawbacks appear as a result of an increase in the output power of an SO ensemble compared to a single oscillator under a simultaneous decrease in the spectral linewidth of the ensemble.

Aim. To investigate the impact of connection topologies, synchronization mechanisms, and oscillator failures on the synchronization of oscillator ensembles.

Materials and methods. The Kuramoto phase model was used to simplify the numerical modeling of synchronization of SOs connected into an ensemble.

Results. A Kuramoto equation for phases of SOs connected in an ensemble was derived, and the influence of connection topologies and oscillator failures on the synchronization parameters of an ensemble of N connected oscillators was demonstrated.

Conclusion. In order to ensure the shortest transition time of an SO ensemble to the synchronous mode, topologies with a higher number of connections between oscillators (e.g., "all-to-all") are preferable. The results obtained confirm the advantages of local connection of an SO ensemble by a common current, thus forming an "all-to-all" topology. This makes the transition time of the SO ensemble to the synchronous mode less dependent on both oscillator failures and the number of synchronized SOs.

Published: November 2024

Introduction. Recent developments in the field of thermal imaging technology and the accumulated experience in instrumental analysis of thermal processes in the patient’s body indicate the prospects of developing new medical thermal imaging systems (thermal imagers).

Aim. Creation of a low-budget domestic thermal imaging system for medical diagnostics with expanded functionality.

Materials and methods. The distribution of temperature over the surface of the human body depends on its internal state and external environment. For each person, this distribution has its own physiological characteristics, the study and interpretation of which can be significant for diagnosing specific pathologies or assessing the general (psychophysical) state of the patient. Analysis of temperature fields on the surface of the human body makes it possible to diagnose various pathological processes manifested in the form of local temperature changes in individual areas. The proposed method for thermal diagnostics involves measuring the temperature at each point of such an area simultaneously (statically) or over a period of time (dynamically). In comparison with conventional approaches, two thermal imaging sensors are used for this purpose. These include a small-sized matrix (thus being low cost) and a point sensor. Such a combination of sensors provides for the necessary discretization of the temperature field image of sufficiently large areas of the surface of the human body, when shooting from a distance significantly reduced compared to the conventional approach.

Results. A conceptual electrical circuit and a layout of a modern thermal imaging system are developed. The advantages of the proposed thermal imager over similar devices are assessed. A method for recording and analyzing temperature in a certain point and temperature fields of both separate areas and large areas on the surface of the human body is proposed and tested.

Conclusion. The conducted testing of a material model of the proposed thermal imaging system using the facilities of large medical institutions in St. Petersburg showed its wide functionality along with simplicity and convenience.
A Versatile Gyro Inclinometer, Adaptive to the Borehole Trajectory, Based on a Uniaxial Angular Rate Sensor
Authors: Binder Ya. I. , Khazov I. A.
Published: November 2024

Introduction. An approach to designing a gyroscopic inclinometer (GI) based on a single uniaxial angular rate sensor (ARS) is developed. It is argued that such an ARS should be considered a modification of a longitudinal GI scheme, preserving the well-known disadvantages of its performance characteristics. The latter include a lack of adaptability to the trajectory, i.e., commensurability of GI errors at different zenith angles. This work sets out to develop a scheme with one ARS in order to achieve a multiple increase in the accuracy of azimuth measurements for vertical and adjacent-to-the-vertical boreholes when the GI is operated in continuous mode.

Aim. To make a GI based on a uniaxial angular velocity sensor more adaptive to the borehole trajectory thought its design modification and a comparative analysis of errors.

Materials and methods. Algorithms for ideal operation of the proposed scheme in continuous mode are synthesized based on matrix transformations of coordinates and Euler equations. The properties of orientation errors are examined using linearization methods, integral calculus, fundamentals of the calculus of variations, and the theory of linear differential equations.

Results. The adaptivity of the modified GI scheme to the borehole trajectory was achieved by means of a structurally provided deviation of the ARS sensitivity axis by a certain angle of non-orthogonality to the GI longitudinal axis. When designing a GI based on the developed approach, it is possible to realize the value of this angle of 20°. For this angle, the increase in the compassing error does not exceed the uncertainty of the ARS drift statistical characteristics, while achieving an effective level of adaptivity to the borehole trajectory in continuous mode.

Conclusion. The developed scheme makes it possible to significantly reduce the influence of the ARS drift on the accuracy of azimuth calculation in the transitional zenith angles area (from vertical to directional boreholes) in comparison with the well-known longitudinal scheme, thereby maintaining an increased initial azimuth accuracy during movement in the initial alignment at the wellhead.

Josef Koch in der IGfH – Sonderheft zum Abschied
Ombudschaft in der Jugendhilfe
Authors: Schruth Peter
Published: November 2024

Schon bald, nachdem Josef Koch die Geschäftsführung der IGfH und die Redaktionsleitung der Fachzeitschrift Forum Erziehungshilfen (ForE) 2003 übernahm, verantwortete er im Heft 4/2003 den Themenschwerpunkt „Chance Beschwerde“ und schrieb im Editorial: „Selten existiert (in der Jugendhilfe, d. A.) eine (…) gerahmte Beschwerdekultur, selten finden sich starke, autonome Selbsthilfeorganisationen von Kindern, Jugendlichen und Eltern und es erscheint schwer in der hoch kommunikativen Betreuungs- und Beziehungsarbeit (ohne Betreuungsverträge zwischen Einrichtungen und Sorgeberechtigten) objektive Bezugspunkte für Beschwerden festzumachen. Häufig wird angeführt, dass geregelte Verfahren in Einrichtungen und Diensten der Erziehungshilfen zum Umgang mit Beschwerden den alltäglichen selbstverständlichen und fehlerfreundlichen Umgang miteinander verstellen. Dabei zeigen Blicke ins Ausland (wie Schottland) und erste Ideen während der bundesdeutschen Heimreformender 70er Jahre, dass bestehende Interessensunterschiede der Beteiligten in erzieherischen Hilfen Anlass sein können, um Beschwerde- und Beteiligungskultur zu stärken.“

„Zudem wird die Situation von jungen unbegleiteten Flüchtlingen kaum in der Öffentlichkeit thematisiert“, schreibt Josef, zu dem Zeitpunkt seit knapp zwei Jahren Geschäftsführer der IGfH, im Editorial des ForE 1/2005 (Themenschwerpunkt: Interkulturelles Handeln) – und platziert damit gleichzeitig das zu diesem Zeitpunkt wenig beachtete, aber aus Sicht der Kinder- und Jugendhilfe hochrelevante Thema.
Selbstvertretung junger Menschen im Machtgefüge der Kinder- und Jugendhilfe − Entwicklungen, Perspektiven und Irritationen
Authors: Wedermann Stefan
Published: November 2024

Die Kinder- und Jugendhilfe steht vor neuen Aufgaben und Umbrüchen, denn das Kinder- und Jugendstärkungsgesetz, das im Juni 2021 in Kraft getreten ist, zielt darauf ab, die Rechtsstellung junger Menschen zu stärken. Neben u. a. Beratungsansprüchen werden die Selbstorganisationen junger Menschen – wie auch anderen Adressat*innen des SGB VIII – in der Kinder- und Jugendhilfe strukturell gestärkt. Öffentliche Träger sollen mit selbstorganisierten Zusammenschlüssen zusammenarbeiten sowie diese anregen und fördern (vgl. §4a SGB VIII). Ein Meilenstein in der deutschen Kinder- und Jugendhilfe, hinter den nicht mehr zurückgetreten werden darf. Mit etwas Abstand zeigt sich aber auch eine Irritation der Rahmung der neuen Aufgabe, denn junge Menschen organisieren sich seit jeher und dies auch ohne Rechtsansprüche im SGB VIII.
