The Influence of Director Characteristics and Company Performances Towards Firm Value
Authors: Widialvanti Auliarahma , Nugraheni Bernadia Linggar Yekti 
Published: July 2024

This study aims to investigate the influence of director characteristics and company performance towards firm value. There’s a lack of studies about how female director characteristics and company performance affect firm value in Indonesia, therefore this study combined measurements of director characteristics and company performance towards firm value. Using a sample of manufacturing firms listed on the Indonesia Stock Exchange (IDX) from 2018 to 2022, this study applies multiple regression to examine the potential positive associations between director characteristics, company performance, and firm value. Director characteristics are measured by two proxies: the representation of female directors and female educational background, while company performances are assessed by return on assets (ROA) and leverage. Firm value as a dependent variable is represented by Tobin’s Q. The findings indicate a positive association between return on assets and leverage to firm value. However, no evidence is found to support the influence of female representation and educational background towards firm value. Keywords: female_directors, education_background, female_representation, firm_performance, Tobin’s_Q
Spatio-Temporal Hierarchical Data Structure Based on Sparse Voxel Octrees for Representation of the Geometry of Time-Variable Three-Dimensional Scenes
Authors: Khorshidiyeh Heidar , Madoš Branislav , Vaľko Dávid 
Published: July 2024

Abstract
The paper deals with the problematics of representation of the geometry of three-dimensional scenes in computer graphics using domain-specific hierarchical data structures based on octant trees or directed acyclic graphs as the means of space saving binary representation of this information. Several hierarchical data structures were introduced in this field in past decades. In this paper we are moving this problematic to the field of the representation of three-dimensional scenes which are rather dynamic in time, so their geometry is changing on the regular basis. We are investigating the influence of this time-variability on the size of the related hierarchical data structure on binary level. We are comparing the approach in which each time step is considered as the stand-alone static three-dimensional scene and therefore is represented by its own hierarchical data structure with the approach when this time-variable scene is considered as the four dimensional space and spatio-temporal sparse voxel octree hierarchical data structure is used for the representation of the geometry of this scene. We tested both approaches on three different scenes which were obtained by voxelization into two different resolutions of polygonal surface models represented originally as the mesh of triangles in Wavefront Object file format. Results of the tests show that spatio-temporal sparse voxel octree is better solution, when we obtained from 1.73 to 2.08 more compact binary representation, in comparison to the solution when time frames were encoded separately as the set of sparse voxel octrees.
A Narrative About Homework in Primary Education – the Perspective of Pedagogical Staff
Authors: Majerčíková Jana 
Published: July 2024

Abstract
The paper discusses the issue of homework in primary education in Slovakia. It attempts to contribute to uncovering the homework narrative that is created and used by its teaching staff and to relate it to the discourse on homework and its place in education in the Anglo-American environment. The research used content analysis of the written products of 30 participants (teachers, educators in children’s school clubs, and teacher’s assistants). Data processing and analysis were carried out by thematic analysis. The results, concentrated in four topics, showed that the homework narrative in primary education is based on homework support. It clearly resonates with the teacher’s expectation of the involvement of the pupils’ parents in its completion. However, it is without the methodical support of the parents from the school. Part of the discourse is also the teachers’ prescription taking into account, particularly, the appropriate number of tasks, their attractiveness, an individual approach when assigning them, and the comprehensibility of homework for all persons involved. Such a setting should reflect potential inequalities between pupils concerning their family background. The narrative revealed details the semantics of school-family relations and the pedagogical strategies of teachers in primary education.
Examining the Utilisation of Learning Techniques and Strategies Among Pedagogy Students : Implications for Self-Regulated Learning
Authors: Seban Peter , Urban Kamila 
Published: July 2024

Abstract
Self-regulated learning is a multifaceted process that involves cognitive, metacognitive, motivational, affective, and behavioural components. These components are interconnected and influenced by contextual factors that shape the overall learning experience. Self-regulated learning empowers students to take control of their learning by utilising effective learning techniques, engaging in metacognitive processes, and fostering motivation and self-efficacy beliefs. The goal of the article is to explore the importance of self-regulated learning in enhancing students’ academic performance and fostering a deep understanding of the learning material. Specifically, this research article explores the utilisation of learning techniques and strategies (LTSs) among pedagogy students, investigating their patterns and preferences for self-studying. The analysis of survey responses from a sample of 76 pedagogy students revealed that the most commonly used LTSs are rereading, note-taking, memorising, and highlighting. The utilisation of LTSs that are empirically considered effective, such as distributed practice, practice testing, and elaborative interrogation, was found to be extremely low. Moreover, the study revealed a lack of comprehensive training in learning techniques and strategies in pedagogy programmes, suggesting that current teachers are not adequately trained to create optimal classroom contexts for developing flexible self-regulatory skills in students. The findings highlight that by incorporating these practices into curriculum, future educators can empower their students to become active learners who select the appropriate strategies and reflect on their learning process. This paper contributes to an understanding of self-regulated learning and the implications of self-regulated learning for educational practices.
Trochlea Dysplasia as the Major Anatomic Risk Factors for Patellofemoral Joint Instability: An Infographic as a Visual Learning Tool
Authors: Vasiliadis Angelo V. , Troupis Theodore , Chrysikos Dimosthenis , Chytas Dimitrios , Noussios George 
Published: July 2024

Abstract
Patellofemoral instability (PFI) is a common condition in children and adolescents, ranging from mild discomfort and mal-tracking to lateral patellar dislocation [1]. A number of anatomical risk factors have been described in the literature, such as trochlear dysplasia, patella alta, excessive tibial tuberosity to trochlear groove (TT-TG) distance, patellar tilt and soft tissue alterations [2]. Among them, TD has been identified as the main anatomical risk factor with the strongest association with PFI [1, 2]. In the study by Dejour et al. [2] radiographically observed TD was identified in 96% of patients with a history of patellofemoral dislocation [1, 2]. Patients with Dejour Type D dysplasia are characterized by a prominent and convex lateral facet with a vertical connection to a hypoplastic medial facet (Figure 1), which provides inadequate tracking of the patella in the trochlea during flexion leading to patella subluxation [2]. Non-operative treatment of lateral patellar dislocation presents a rate of re-dislocation up to 70% within 24 months of the first episode [3]. Sulcus deepening trochleoplasty is indicated for Type B and D dysplasia, in order to improve patella tracking, reduce the rate of re-dislocation and achieve good functional outcomes [2, 4]. Trochlea dysplasia is defined as a shallow or flattened groove with decreased resistance to lateral patellar translation. TD can be assessed on computed tomography (CT) and magnetic resonance imaging (MRI) with the use of overlapping axial images and are able to show perfectly the global shape of the femoral trochlea [2]. The thresholds for identifying trochlear dysplasia are established based on the sulcus angle ≥ 145°, medial/lateral trochlea facet asymmetry < 40%, trochlear depth < 3 mm and lateral trochlear inclination ≤ 11° and therefore it can be used in young adolescents [4, 5]. A deep knowledge of anatomic variations and abnormalities of the patellofemoral joint, which may predispose to PFI, is crucial in order to choose the appropriate treatment for each patient.
Active Energy Management for Enhanced Engine Transient Operations

Published: July 2024

Combat aircraft often require the engine to accelerate as fast as possible in response to the demand of maneuvering. The engine acceleration rate, however, is limited by the compressor surge constraint, which prevents more fuel addition that, otherwise, could provide for higher net shaft torque, and thus, faster acceleration. This paper examines the idea of using the electric starter/generator (ES/G) system to provide additional net shaft torque during this critical phase of acceleration. The idea is examined by simulations using a quasi-one-dimensional dynamic compressor flow model coupled with a lumped combustor–turbine model. A notional single-spool turbojet with a low overall pressure ratio is modeled and simulated. Simulation results suggest that an ES/G, when used as an electric-assist motor during acceleration, can help the engine to accelerate roughly 11, 48, and 70% faster compared to the case without ES/G participation, by using electric power roughly equivalent to 0.1, 1, and 3% of full-speed fuel combustion power, respectively. Furthermore, the respective increase in the acceleration rate leads to an additional 19, 80, and 113% of propulsion impulse, respectively (i.e., thrust integrated over time), during the first 5 s following the acceleration command.
Effect of Inlet Geometry on Film-Cooling Effectiveness from Shaped Holes
Authors: Wang Hanlin , Wright Lesley M. 
Published: July 2024

Modern gas turbine engines require a sophisticated cooling system design to achieve higher power output and efficiency. This study investigates the potential effect of noncylindrical inlet geometries on the performance of laid-back, fan-shaped film-cooling holes using the pressure-sensitive paint measurement technique on a flat plate. On the basis of a common pattern of outlet geometry, racetrack-shaped inlet geometries with aspect ratios of 2:1 and 4:1 were tested along with traditional cylindrical inlets. The coolant flow conditions range from [Formula: see text] = 0.3–1.5 and DR = 1 and 2. The mainstream turbulence intensity is held at 6%. Test results show that the shaped inlets provide a higher area-averaged film-cooling effectiveness over the cylindrical inlet using the same amount of coolant. For the 2:1 inlet, an advantage of 20% higher effectiveness could be maintained for DR = 1, while for DR = 2 this advantage is reduced to 10%. For the 4:1 inlet, when the coolant momentum flux ratio [Formula: see text] < 0.5, a similar or slightly higher improvement can be obtained, but when [Formula: see text] > 1, the advantage diminishes with the growing I to approximately 5%, at [Formula: see text] = 2.25. Regarding discharge coefficients, the 2:1 inlet geometry is similar to the cylindrical inlet. For the 4:1 inlet, it is 2–5% lower or nearly equivalent.
Transarterial embolization of type 2 endoleak using coils and N-butyl cyanoacrylate: The importance of treating the nidus and sac branches
Authors: Okumura Kenichiro , Ogi Takahiro , Matsumoto Junichi , Asato Nobuyuki , Sugiura Takumi , Yokka Akira , Kozaka Kazuto , Kobayashi Satoshi 
Published: July 2024

Background:
Transarterial embolization (TAE) of the nidus and branches prevents aneurysm sac growth due to type 2 endoleaks (T2EL). Embolization materials include coils and liquid embolic substances such as N-butyl-2-cyanoacrylate (NBCA) glue, a type of liquid embolic glue. However, when the nidus is characterized by heterogeneous perigraft opacity on computed tomography imaging with an ill-defined boundary within the sac, although reaching the nidus is possible, thoroughly packing it with embolic agents may prove challenging, sometimes leading to the alternative of embolizing the associated branches. This approach involves embolizing the branches close to the nidus and not distal from it.

Objectives:
Therefore, we aim to evaluate the efficacy of TAE for the endoleak nidus and its associated branches versus embolizing its associated branches alone directly connected to the nidus in preventing aneurysm sac enlargement after T2EL, comparing mid-term follow-up results.

Material and Methods:
In a single-center retrospective cohort study, we reviewed consecutive 59 patients who underwent TAE for T2EL from September 2017 to August 2022. After excluding cases with <6 months follow-up or without abdominal aortic aneurysm, 40 patients were included in the analysis. Initial treatment for all patients included attempts at direct embolization of the endoleak nidus and side branches using coils and NBCA glue. Even if the nidus was reached, if embolization of the nidus proved difficult, the directly connected branches were embolized instead. Data were analyzed using the Kaplan–Meier curve for estimating sac enlargement freedom, with the primary outcome being aneurysm sac diameter change post-T2EL embolization.

Results:
No visible endoleak nidus was detected in any patient after TAE. Of all patients (n = 40), 60% (n = 24) underwent embolization through direct cannulation to the nidus. Direct TAE involving the nidus and main branches with coils, supplemented with NBCA glue, considerably hindered sac enlargement (P < 0.0001). Of 14 patients with sac enlargement, 72% (10 patients) had unsuccessful direct TAE, resulting in a significant association (P = 0.006). On the other hand, 77% (20 of 26 patients) without sac enlargement experienced successful direct TAE. Three patients displayed sac enlargement even after successful direct TAE using only NBCA glue (P = 0.04).

Conclusion:
Direct TAE of the endoleak nidus, using coils and supplemented with NBCA glue as necessary, is effective in preventing sac enlargement after T2EL embolization.

Published: July 2024

Objectives
The vast majority of BCOR (BCL6 corepressor) sarcomas occur in the pediatric population and include different clinico-pathologic entities. This study evaluates morphology, immunohistochemistry and clinical outcome in pediatric BCOR sarcomas.

Material and Methods
Children, aged ≤ 18yrs, diagnosed to have translocation negative Ewing-like sarcoma, clear cell sarcoma of the kidney and primitive myxoid mesenchymal tumor of infancy, over a period of five years were included. Immunohistochemical staining for BCOR antibody was done and the cases with BCOR overexpression were subjected to a further immunopanel comprising of special AT-rich sequence-binding protein 2 (SATB2), Transducin-Like enhancer of split-1 (TLE1), Cyclin D1 and NKX2.2. The clinical outcome of patients with BCOR overexpression was assessed.

Results
BCOR overexpression was seen in 16/42 cases; Five were primary soft tissue tumors, three were primary bone tumors, seven were clear cell sarcoma of the kidney and one primary renal sarcoma. The median age of this group was 3.5 years (range 2–18 years) with male predominance (75%). All the BCOR positive tumors showed statistically significant morphological and immunohistochemical overlap. 4/16 did not take treatment at our center. Of the 12 who received treatment, 8 are in Complete Remission 1 (CR1). The mean event-free survival (EFS) and overall survival (OS) were 51.89 months (95% CI: 37.36-66.42) and 62.08 months (95% confidence interval (CI): 52.85-71.30) respectively.

Conclusion
BCOR sarcomas did not show any statistically significant histological and immunohistochemical differences, thus reiterating the morphologic continuum of these clinically distinct tumors.
Over-the-counter cosmeceuticals: Exploring usage patterns and attitudes among Indians
Authors: Bhatnagar Abhishek , Oberoi Bhavni , Thayumanavan T. , Ayub Afreen 
Published: July 2024

Objectives:
The study’s objectives were to find the prevalence of over-the-counter (OTC) usage of skin, nail, and hair care products and to understand the knowledge, attitudes, and practices (KAPs) of the Indian population presenting to a non-dermatology outpatient department (OPD) for various indications concerning this usage.

Materials and Methods:
This was a cross-sectional questionnaire-based study, conducted over a year, in which 668 consenting Indians aged 18–60 years, representing various socioeconomic backgrounds were surveyed through Google Forms regarding the OTC cosmeceutical usage in a non-dermatology OPD.

Results:
This KAP study was conducted on 668 participants, of whom the majority were middle-aged males (481 [72.01%]), with a diverse socioeconomic range, with the upper-middle class making up the largest segment (264 [39.52%]). Allopathy was the primary treatment choice for 347 (51.95%) of participants, with 566 (84.73%) preferring professional healthcare over self-medication. Social media was a significant source of skincare information, with Google Ads (279 [41.8%]) and Instagram (84 [12.6%]) being popular platforms. While doctors’ advice influenced 270 (40.4%) of participants in their skincare choices, word-of-mouth played a role, with 251 (37.57%) agreeing it was helpful. OTC usage was found to vary by socioeconomic class and treatment type. Oral OTC products were preferred for skin health, especially in the upper class, while fairness creams were more common among the lower class.

Conclusion:
Despite the growing reliance on social media for skincare information, traditional sources such as word-of-mouth and TV still hold sway, indicating a mix of modern and conventional influences. The frequency and type of OTC product usage varied across socioeconomic classes, with oral products like vitamin supplements leading in the upper class and fairness creams leading in the lower class, reflecting the societal pressure for a fair complexion in this subset.
