Nuances and Clarifications Concerning the Notions of Therapeutic Relationship and Working Alliance (Therapeutic Alliance)
Authors: TITULESCU Paul Robert
Published: October 2024

Our individual attachment style, or the evolving contact style derived from it, influences the characteristic manner in which we approach others and the way we interpret the world and interactions in general. The complex process of psychotherapy is essentially comprised of two major parts: the therapeutic relationship and techniques. The therapeutic relationship is difficult to define, even more challenging to clinically understand, and empirically studying it rises difficulties. However, despite the existence of various psychotherapeutic schools, it is universally accepted that a quality therapeutic relationship is a necessary condition for favourable therapy outcomes. In this paper, we aim to contribute to the vast field of psychotherapy with some clarifications that we believe are useful concerning two notions used in practice and specialised literature: the therapeutic relationship and the therapeutic alliance (working alliance).Article’s history: Received 25th of October, 2023; Received in revised form 24th of November, 2023; Accepted 27th of November, 2023; Published as article in Volume I, Issue 1, 2023.Copyright© 2023 The Author(s).

Rechtsfragen der Bezahlkarte im Asylbewerberleistungsrecht
Authors: Seidl Julian
Published: October 2024

Die Einführung der Bezahlkarte als Mittel der Leistungserbringung im Asylbewerberleistungsrecht wirft eine Vielzahl von Rechtsfragen auf, mit deren Auseinandersetzung Rechtsprechung und Rechtswissenschaft noch am Anfang stehen. Vielfach werden die Sozialgerichte zu überprüfen haben, ob die Leistungsbehörden das ihnen bei der Wahl der Leistungsform eingeräumte Ermessen korrekt ausgeübt haben. Als Hilfestellung für die Praxis möchte der vorliegende Beitrag den einfachgesetzlichen und verfassungsrechtlichen Rahmen für den Einsatz der Bezahlkarte aufzeigen sowie die zu erwartenden Problemfelder skizzieren.
Pflicht des Arbeitgebers zur Mitwirkung an einer Maßnahme zur stufenweisen Wiedereingliederung in das Erwerbsleben – zugleich eine Besprechung der Entscheidung des Arbeitsgerichts Aachen vom 12.03.2024 – 2 Ga 6/24
Authors: Palsherm Ingo
Published: October 2024

In der zu besprechenden Entscheidung geht es um die Verpflichtung des Arbeitgebers zur Mitwirkung im Hinblick auf die von seinem arbeitsunfähig erkrankten Arbeitnehmer begehrte stufenweise Wiedereingliederung in das Erwerbsleben. Prozessual wird das Ansinnen im einstweiligen Rechtsschutz verfolgt. Die Entscheidung ist nicht nur für die Beratungspraxis arbeitsunfähig Erkrankter interessant, vielmehr markiert sie auch eine Schnittstelle von Arbeitsrecht und Sozialrecht. Denn das konkrete Arbeitgebervorgehen deutet auf die Intention einer personenbedingten Kündigung und damit (wahrscheinlich) Arbeitslosigkeit für den Betroffenen hin.
Körperliche Selbstbestimmung
Authors: Röthel Anne
Published: October 2024

Physical self-determination is a human right. Nevertheless, physical self-determination has never been an equal right for all people, but a right with gradations. To this day, physical self-determination is a different right for children and people in care than for "normal" adults. Anne Röthel explains how the dogmas, discourses and interpretations of the physical self-determination of patients, children, incapacitated persons and those in care have developed since the beginning of the 20th century. The focus is on commonalities and patterns with regard to actors, triggers and arguments. Her studies shed light on the basis of which doctors' decision-making prerogatives were derived, why a parental right of chastisement seemed right for a long time, why adolescents need their parents' consent for medical decisions and how the legality of coercive treatment is determined. It also serves to show that every legal concept of physical self-determination eventually leads to a dilemma.

Bovine Lactoferrin: Physiological Importance, Extraction and Application
Authors: Liliane de Vasconcelos Marta , Kukuljan Sonja , Vasiljevic Todor
Published: October 2024

Lactoferrin (LF) is one of the minor milk proteins that has been gaining attention for its beneficial physiological functions to human health, as an antioxidant, antimicrobial, anti-inflammatory, immunomodulatory, anti-viral and bone growth agent. These characteristics are partly attributed to its ability to bind iron, which results in regulating the sequestration and release of iron in the body and partly due to its ability to interact with the molecular and cellular components of pathogens and their hosts. For this reason, LF is marketed as a functional component in various types of products, including infant formula, and in tablets or other types of supplements for children and adults. Bovine LF (BLF) is the main commercial protein ingredient from large-scale extraction using various technologies. The use of cationic exchange chromatography is the most common technology, and allows BLF to be extracted with around 95% purity and 87–93% of the isolated protein. Due to its characteristics and its various health benefits, BLF has also been studied as an additional component in new therapeutic applications in serious diseases such as upper and lower respiratory tract infections and COVID-19, cancers, for use in dermatology and regenerative medicinal engineering.

Authors: Huang Jinhai , Wang Yiran , Li Kexin , Yang Xinning
Published: October 2024

This chapter explores the application of anterior segment optical coherence tomography (OCT) in the diagnosis and treatment of corneal ectasia diseases, with a particular focus on keratoconus, post-refractive corneal ectasia, and pellucid marginal degeneration (PMD). OCT provides high-resolution imaging of corneal sublayers, assisting in early detection and tracking of disease progression. For corneal ectasia diseases, OCT assists in identifying characteristic changes in corneal thickness and morphology, guiding treatment strategies such as contact lens fitting, intrastromal corneal ring segments (ICRS) implantation, corneal crosslinking (CXL), and corneal transplantation. OCT’s precision and reliability make it a valuable tool in managing these challenging corneal conditions, facilitating improved patient outcomes.
Uterine Incision Techniques
Authors: M.A. Nasr Abubakr
Published: October 2024

Uterotomy, being the critical step in cesarean delivery, evolved history over milestones until the recent practice of lower segment hysterotomy. The site of primary uterotomy in the lower uterine segment as well as other factors has been related to cesarean scar defect. The debate on making uterotomy involves the minute details of incision creation, technique, extension technique, extension direction, and relationship with the urinary bladder. Uterotomy closure needs to be addressed with reference to number of layers, suture material type, technique of suturing, and anatomical approximation of uterotomy. The impact of uterotomy technique on wound healing in addition to other factors needs attention. Incomplete healing manifests clinically in obstetric practice with significant morbidity such as uterine rupture and scar dehiscence. The impact of uterotomy healing created a significant burden on gynecologic practice. Future challenge is to mitigate morbidity and create measures for effective prevention of morbidity. The preventive measures at primary and secondary level are not necessarily based on reducing cesarean section rate but on standardized technique, training, wound healing, and monitored practice.
La lupa del cuidado: el derecho al cuidado como categoría conceptual y herramienta para la reinterpretación de los derechos
Authors: Pinedo Egurrola Maria Paula
Published: October 2024

Este texto pretende argumentar que, al comprender el cuidado como una categoría conceptual, se puede reinterpretar la manera en la que las normas están escritas y encontrar, en el centro de ellas, el interés del legislador por garantizar el cuidado a quienes lo necesitan y el autocuidado de quienes lo ejerzan. Así las cosas, se busca ayudar a los lectores a reconocer el alcance del cuidado y utilizarlo como una “lupa interpretativa” para encontrar en el ordenamiento existente la presencia del cuidado como derecho y así lograr darle nuevos alcances a la norma. Lo anterior, a partir de un análisis de la Constitución Política Colombiana.
Implementation of Green Accounting to Support High-Quality SDGs Disclosure and Enhance Stock Prices
Authors: Dianty Astari
Published: October 2024

Natural resources are the primary raw materials produced by companies within the Mining Sector. Their products are not only needed by the Indonesian community but also by people in other countries. In the context of business expansion, the mining sector requires significant funding. In reality, based on data obtained from the Indonesia Stock Exchange, the stock prices in this sector continue to decline. The fact that many companies disclose Sustainability Development Goals in a non-detailed manner is a cause of the decline in a company's reputation in the eyes of the public. The suboptimal disclosure of Sustainable Development Goals is due to the fact that many companies in the mining sub-sector are neglecting their obligations for reclamation funds, commonly referred to as Green Accounting. The aim of this research is to analyze that relationship. The totalresearch observations are 45 companies and will be tested using path analysis. The research results indicate that the implementation of Green Accounting can enhance the quality of Sustainability Development Goals disclosure, High-quality Sustainability Development Goals disclosure can increase Stock Prices, and the implementation of Green Accounting can boost Stock Prices through high-quality SDGs disclosure.

Published: October 2024

The purpose of this research is to understand security perceptions and customer trust in influencing DANA e-wallet customer loyalty in the city of Malang. This type of survey research uses a quantitative approach, the sampling method used is purposive sampling because the sample is users of the DANA e-wallet application who have a transaction history using the DANA application, and the sample size is 100 people. The data collection method uses a questionnaire. Multivariate data analysis and using multiple linear regression and SPSS statistical tools.
The results of the partial test research show that the trust variable influences and is clearly proven to influence loyalty. Meanwhile, the perception of security variable in transactions has not been proven to significantly influence loyalty. This is possible because the perception of transaction security is considered not to be the main factor in carrying out online transactions and consumers have made selective perceptions where they have modified the ideas and information messages they receive even though they conflict with the attitudes and beliefs they have learned. However, from the simultaneous test, the perceived security and trust variables have a positive and real proven effect on customer loyalty of the DANA E-Wallet application.

In the context of globalization and increasingly tight business competition, employee performance has become an important factor that determines organizational success. Motivation and work environment have been proven to have a significant effect on individual performance. This research uses a survey method with a quantitative approach. The research population was employees of PT X in Malang, with a sample of 100 people selected purposively. The research instrument is a closed questionnaire with a Likert scale that measures work motivation, work environment and employee performance. Data were analyzed using descriptive analysis, correlation tests and regression. The research results show that work motivation and work environment have a positive and significant influence on employee performance. The correlation test shows a positive relationship between motivation and employee performance (r = 0.65, p < 0.01), as well as between the work environment and employee performance (r = 0.60, p < 0.01). The regression test shows that motivation (β = 0.50, p < 0.01) and work environment(β = 0.45, p < 0.01) together explain 70% of employee performance variability (R² = 0.70). This research emphasizes the importance of motivation and work environment in improving employee performance. Therefore, management must consider these two factors simultaneously in its human resource development strategy to achieve optimal productivity and job satisfaction.

Penelitian ini menggunakan metode gabungan kualitatif dan kuantitatif, dengan pengumpulan data melalui wawancara dan analisis dokumen. Sampel penelitian terdiri dari 120 berkas klaim pasien rawat inap BPJS Kesehatan yang diajukan pada bulan Mei 2023. Hasil penelitian menunjukkan bahwa tingkat pengetahuan petugas koding tentang review koding sudah memadai, namun pelaksanaan audit koding masih dilakukan sendiri oleh petugas koding tanpa melibatkan dokter dan belum ada instrumen baku dalam pelaksanaan audit. Tingkat ketepatan kode ICD-10 masih terdapat 11,57% kode yang tidak tepat, seluruhnya merupakan downcoding, yang berpengaruh terhadap rendahnya pendapatan rumah sakit dan bisa menyebabkan kerugian. Tingkat kelengkapan koding sudah cukup baik dengan hanya 1,67% yang tidak lengkap. Tingkat kecepatan pelaksanaan pemberian kode masih terdapat kelambatan sebesar 3,33% lebih dari 4x24 jam. Kendala utama dalam pelaksanaan koding adalah tulisan dokter yang tidak jelas, diagnosis yang kurang spesifik, dan diagnosis awal yang belum final. Penelitian ini merekomendasikan agar pelaksanaan audit koding melibatkan dokter sebagai penentu dan penulis diagnosis serta membuat umpan balik secara tertulis dan berkala. Sosialisasi tentang pentingnya kejelasan penulisan diagnosis dan tindakan medis perlu ditingkatkan dengan mewajibkan dokter menulis diagnosis secara spesifik.
Avlönat hushållsarbete i Sverige 1890–1939: Kvinnor, klass och hierarkier i en brytningstid
Authors:   ,   Karlstad University, Vedin Sofi
Published: October 2024

The aim of this dissertation is to examine how the practices of paid domestic work (including advertising for labor) constructed, maintained, challenged or transformed hierarchies in relations between women in Sweden 1890–1939. The study thus contributes to our understanding of female labor and class relations: a less researched area compared to male work outside the home.  Domestic workers were one of the largest female occupational groups during the period. Until the 1920s, domestic workers were subjected to a live-in system, where the employee lived in the employer’s home. The study analyzes over 13 000 work advertisements and nearly 300 questionnaire responses written by former domestic workers and employers, focusing on how class, gender and labor relationships were performed, and everyday practices in the household. The analysis is grounded on theories on practices, performative practices, class, gender, and theories on how work is valued.  The study shows that previously established titles and divisions of labor among domestics (such as naming domestics working alone as ‘ensamjungfru’ or assuming ‘barnjungfrur’ only worked with child care) were performative. Both employers and employees constructed domestic work as a calling for working class women, making class relations seem innate. It divided women into categories of important (made to be served) and non-important (made to serve). Domestic workers were subjected to the idea that it was their natural, moral duty to serve middle- and upper class women.  As ideas of equality began to emerge in Swedish politics, employers attempted to integrate paid domestic work in a modern society by portraying the class relations as leveled and equal in the advertisements. However, when domestic workers abandoned the live-in system in the 1920’s, their numbers declined in the 1930’s, employers showed a desire to retain the live-in system, thereby preserving the anachronistic features of domestic work.

Published: October 2024

The size of area of plantations of fast-growing tree species, established on agricultural land in the Czech Republic (CR), is on the rise. In order to gain saw timber, it is necessary to choose other species (example: Salix spp. and Populus spp., their resulting product is wood chips), one of which could be Paulownia spp. In 2015, an experimental plot with the species of Paulownia tomentosa and two hybrids of Paulownia Shan-Tong and Paulownia Hybrid 9501 were established in South Moravia. The plants were periodically pruned up to a height of 3 m. After six years, Paulownia Hybrid 9501 had mean height of 9.4 m and DBH of 12.8 cm, P. tomentosa 7.3 m and 10.3 cm, respectively, and P. Shan-Tong 5.2 m and 9 cm, respectively. These values are well below the average, in comparison with those declared by the sellers. The limited growth was presumably caused by less precipitation and a shorter growing season, in comparison with the climate characteristics of the humid subtropical zone in which Paulownia species originated. It appears that Paulownia Hybrid 9501 could grow in conditions similar to those in South Moravia, however, with a slower growth.

Published: October 2024

The bark beetle calamity that hit the Czech Republic has been reflected, among other things, in the approach of administrative authorities and courts reviewing administrative acts. The article is an expert report that provides information on the judgment of the Municipal Court in Prague, which reflects the current approach of the courts to the assessment of offences consisting in neglect of forest care during the bark beetle calamity. The example of the state entity shows how this entity uses technical and professional security in the case of forest care during a bark beetle calamity. By analyzing the court decision, it was concluded that it is necessary to strictly comply with the obligations of the forest manager or owner to ensure forest protection against bark beetle calamity, but it should not become a precedent against small owners who do not have the personnel and technical capabilities of large forestry companies. According to the conclusions, it is evident that the court decision imposes high requirements on the forest owner, which the small owner is not able to meet. The article invites a discussion on whether the state should take a more active role in measures against bark beetle calamities.

Authors: Ferfouri Abdellah , Jerković Damir , Kari Aleksandar , Živković Saša
Published: October 2024

A computational analysis was carried out in order to study the effect of solid rocket motor operating parameters on the trajectory elements of 155mm rocket-assisted projectile. Two numerical solutions have been programmed for this purpose. The first for the rocket motor internal ballistic calculation. The second is intended for the six degree-of-freedom (6-DOF) trajectory determination for both unpowered and powered flight. The effect of three operating parameters of the solid rocket motor on the trajectory elements was taken into account, namely: (1) thrust-time profile (neutral, regressive or progressive), (2) working time and (3) ignition delay. The results obtained following this analysis are helpful as a preliminary stage in the design of extended range projectiles in order to optimize flight performance.

Published: October 2024

The aircraft safety is one of the most important things when thinking of designing and manufacturing the airplane. During the flight, there is a probability of lightning occurrence which may cause catastrophic consequences. In order to avoid potential aircraft damage, the aircraft must be protected against lightning effects. Metallic components should be bonded to the airframe, while the airplane design must secure that possible lightning strike would not endanger the plane, the crew and the passengers. In this paper, the compliance of "Sova" aircraft design with certification requirements regarding lightning protection will be analyzed and shown.

Development of liner for case-bonded grain with end-burning configuration
Authors: Kovačević Tihomir , Mijatov Slavko , Crnalić Alen , Gržetić Jelena , Kuprešak Darko , Brzić Saša
Published: October 2024

This paper deals with the potential to manufacture case-bonded propellant grain with the end-burning configuration. The end-burning configuration is not quite suitable for case-bonded architecture due to problems related to structural integrity. One approach to address this issue is to insert a liner between thermal insulation layer and the composite propellant, which absorbs stress generated during curing process and exploitation conditions. The prepared liner is a highly elastomeric material, based on hydroxyl-terminated polybutadiene (HTPB) and castor oil (CO). The amount of curing agent, isophorone diisocyanate (IPDI), is higher to establish a covalent bonding and thus good adhesion between the liner and the propellant/thermal insulation. CO provides more anchoring sites since it has higher functionality of HTPB and, in other hand, isotropy of the liner making it more able to withstand and reduce accumulated stress within the propellant grain. The molar ratio between prepolymer (HTPB and CO) and IPDI was varied and cured material was subjected to an unaxial tensile test and examination of adhesion with propellant using a peel test.

The translation of unmanned systems into autonomous systems is increasingly prevalent in many researches. In this paper, the implementation of the existing algorithms on an unmanned ground platform was performed, as well as the validation of the obtained results in laboratory conditions. First, a simulation model was used to demonstrate the justification of the algorithms, and then the implementation was done on an unmanned platform. The results obtained by validation showed that the robotic platform can successfully perform tasks such as going to the desired location, returning to the initial position, as well as following the operator. In doing so, dynamic obstacles were used that the robotic platform successfully managed to overcome and reach the desired target.

Robots and autonomous systems are an evolving industry for the military. Although the military's interest in autonomous systems has been existed for decades, the use and application of such systems in experiments and in on the ground operations is relatively new and growing. One of the basic functions of the autonomous unmanned ground vehicle (UGV) is "Follow me", where the UGV follows a person or another vehicle (object). The basic sensor used to determine the position of the UGV in relation to the object is the ultra-wideband sensor (UWB). UWB wireless technology consists of tag which is worn by person and anchors on the UGV and has high precision and transmission rate. It is of fundamental interest that the UGV follows exactly the path followed by the person. At the same time, the UGV has to avoid static and dynamic obstacles that are on the way. This paper presents the impact of dynamic and static obstacles, which can be found in real situations, between the UGV and the person. The results of measuring the angle and distance between the tag and the anchor using obstacles of different dimensions and in different positions are given. Also, different distances between tag and anchor were considered, in order to find the optimal distance.

This paper gives a proposition for laboratory equipment and its use for simulation of effects of network topology and link state reconfiguration during battlefield operations. All equipment presented in this paper is based on open source software solutions and well-known hardware development platforms in order to minimize equipment cost as well as provide a simulation environment that is independent of any single manufacturer. Utilization of open source solutions gives us a level of security as it lessens a chance of traditional vendor abuse in more unfortunate circumstances. The core of the laboratory is based on a GNS3 simulator, which can be installed on all three major operating systems (Linux, Windows and Mac) and has the capability of simulating a network that can be added in between two physical end devices that we wish to test in various battlefield scenarios using highly available network adapters. In addition to that, we will focus on network intermediate devices (switches and routers) that are not dependent on any single manufacturer and are open source solutions that can be used for future development of secure and fully-known equipment. We present expected results for the transition of encrypted and unencrypted traffic.

The introduction of digital technology in the process of creating topographic maps significantly changes the way spatial phenomena are used and presented. Geographic Information Systems (GIS) represent a modern tool that enables access to analysis, and interpretation of spatial data in digital form. In the context of military education, particularly in the teaching of Military Topography, GIS provides faster, more precise, and more detailed terrain visualization, which is essential for planning and conducting military operations. The paper compares the use of GIS technology with traditional methods of orientation and terrain analysis. It presents modern informational devices for geolocation and orientation in the field, used in the realization of thematic teaching content and special forms of teaching in the subject of Military Topography at the Military Academy. The impact of these devices on the quality and efficiency of military training was explored, and the use of these devices during extreme weather conditions was analyzed. Recommendations for further research and improvement of the teaching process in this subject are also given.
Standard cumulants-based automatic modulation classification performance under colored noise channel conditions
Authors: Božović Rade , Orlić Vladimir
Published: October 2024

Automatic modulation classification (AMC) represents a wide used technique for signal processing whereas modulation format of received signal is not a priori known. It is of crucial importance for a variety of both military and commercial communications. Due to the low algorithm complexity, hardware requirements and the other relevant practical aspects, the algorithms based on fourth and sixth-order cumulant structures, and generally higher order statistics, remain competitive and interesting research topic. Signal degradation due to the presence of noise significantly deteriorates AMC performance. In this paper, performance of standard cumulants-based AMC algorithms is analysed in context of colored noise impact. This was done through Monte-Carlo simulations conducted in Matlab software in a propagation environment with colored noise channel.

Published: October 2024

In this paper, the level crossing rate of the Nakagami-m random process will be determined. To calculate the level crossing rate we will determine the mean value of the first derivative of the Nakagami-m random variable. This mean value is determined using the joint probability density of the Nakagami-m random variable and its first derivative. The level crossing rate of the Nakagami-m random process is one of the statistical characteristics of another type of telecommunication system performance analysis.

Published: October 2024

This paper explores the effects of tempering temperatures on the mechanical properties of G42CrMo4 cast steel, a versatile alloy commonly used in automotive and construction industries. Tempering, a critical step in the heat treatment process, aims to reduce residual stresses and enhance material reliability. The study investigates the influence of tempering temperatures (450°C and 600°C) on the steel's strength, ductility, and hardness through a series of experimental investigations, including heat treatment, machining, and tensile testing. Results indicate that while normalization treatment offers moderate strength and good ductility, quenching and tempering at 450°C significantly increase strength at the expense of ductility. Conversely, tempering at 600°C strikes a balance between strength and ductility.

Published: October 2024

Efficient removal of antibiotic residues from the water using environmentally friendly and zero-waste technologies represents an emerging challenge. The increasing development of photocatalytic materials needs a comprehensive and systematic approach to understand the principles behind their performance. In this contribution, the Cu-decorated TiO2 nanoparticles were prepared using various input amounts of Cu (0.5 - 2%), employed for photocatalytic degradation of ciprofloxacin solution (30 mg photocatalyst per 50 mL of solution), and compared to bare TiO2 at the same concentration. The observed performance improvement of investigated photocatalytic material compared to bare TiO2 upon decoration with Cu was discussed from various aspects. Some of them include: morphostructural changes (increase of active surface for photocatalysis upon reduced agglomeration), chemical effects (the improved generation and reactivity of active oxygen species upon modification of their adsorption properties), and modification of photochemical properties of the semiconductor material itself (impact of metal decoration on the band gap structure).
