The Role of Corporate Social Responsibility in Supporting SDGs: A Propriety and Fairness Perspective
Authors: Indarto Stefani Lily , Asmara Gregorius Yoga Panji , Purwoko Agustinus Joko
Published: October 2024

Introduction: Increasingly complex environmental challenges demand transparent and accountable measurement of corporate social responsibility (CSR). To create corporate value and monitor social, environmental, and economic impacts, companies and governments collaborate to promote ethical CSR practices and meet existing regulatory requirements, while supporting transparency and accountability in achieving the Sustainable Development Goals (SDGs). However, varying CSR measurement standards often make it difficult to compare performance between companies.
 
Objective: To uncover how stakeholders define the propriety and fairness of companies to achieve the SDGs.
 
Method: Research data were obtained from interviews with company leaders/internal auditors/external auditors/teams involved in the company's CSR evaluation process totaling 81 people. The data collection process was carried out in a hybrid manner.
 
Results and Discussion: In terms of regulations, most companies have complied with regulations related to transparency, financial reporting, and CSR. In terms of propriety and fairness, CSR costs cannot be classified as income, but rather as a reduction in taxable income (expenses). However, it turns out that there are still companies that include CSR costs in other income.
 
Research Implications: This study develops a model for assessing the propriety and fairness of CSR in sustainability reporting, including the social and environmental impacts of its business to support the achievement of SDGs.
 
Originality/Value: This study produces a measurable assessment of the propriety and fairness of corporate CSR, which supports SDGs in improving corporate accountability and transparency.
Rediscovery and Restoring Forgotten Principles: Returning to the Past to Transform and Shape VET for the Future. Back to the Basics in VET
Authors:   Sofia university- Bulgaria, Faculty of Pedagogy ORCID: 0009-0008-0863-1516, Vasilev Iliyan
Published: October 2024

The article explores the historical foundations and contemporary practices of Vocational Education and Training (VET), uncovering a cyclical relationship between past and present methodologies. It begins by analysing the traditional apprenticeship systems of medieval Europe and their counterparts in Asian contexts, demonstrating how these early models laid the groundwork for modern vocational education. The article then traces the historical origin of VET in response to shifting economic conditions and technological advancements, identifying key contemporary practices—such as competency-based education, work-based learning, and experiential learning—as rebranded versions of historical approaches. The analysis emphasizes that many of these so-called “innovations” are not entirely new but are instead adaptations of time-tested methods that have been revitalized to address current educational demands. This historical perspective underscores the importance of integrating traditional practices to enhance the effectiveness and relevance of modern VET systems. The discussion stresses the importance of learning from historical experiences to inform future developments in vocational education, suggesting that a deep understanding of VET’s historical context can provide valuable insights for educators and policymakers alike. The article also addresses the potential pitfalls of renaming and rebranding educational approaches, which can lead to misleading perceptions and adverse effects, hindering educators and policymakers from recognizing foundational principles that remain pertinent today. Additionally, the uncritical dismissal and rejection of past educational principles signifies a denial of the cultural and educational traditions that informed their development and shaped them. Acknowledging and recognizing these historical influences can enrich contemporary educational frameworks and promote a more nuanced understanding of the current educational landscape.

Published: October 2024

The World Health Organization (WHO) reports that over 11 million individuals get burns annually, resulting in 180,000 fatalities. A burn is a condition resulting by heat, chemical agents, electrical currents, or other forces that inflict tissue damage. Burns primarily impact the skin, however they may also include deeper structures, including bones and muscles. Upon combustion, the skin forfeits its primary functions, including protection against the external environment, infections, moisture evaporation, and thermal regulation. Based on the burn's stage, the patient's health, and the burn's etiology, it is essential to choose the most suitable therapy. Personalization and interdisciplinary teamwork are essential for the effective therapy of burn victims. This thorough study compiles and examines the existing treatment modalities, emphasizing current advancements in topical therapies, wound debridement, dressings, skin grafting, nutritional support, pain management, and scar tissue therapy.

Purpose: Physical condition is an essential element required by tennis athletes. Without proper physical conditioning, players cannot perform optimally. The physical condition of tennis athletes at Club Nusalima, Pekanbaru, Indonesia, is still not optimal, as evidenced by their low achievements this year, with no athletes ranked nationally by Pelti. Two of the most important physical conditions required by tennis players are agility and speed. Methods: This study aimed to determine the effect of a training method using a holistic approach on improving the physical condition—specifically agility and speed—of tennis athletes at Club Nusalima, Pekanbaru, Indonesia. The research was conducted as an experimental study using purposive sampling, with a sample consisting of 10 young athletes aged 15-17 from the club. The research design used was a "One Group Pretest-Posttest" approach. The instruments used to collect data were the 505 Agility Test and the 20-meter sprint test for speed. Results: The data analysis technique used was the t-test with a significance level of 5%. For agility, the results showed that the t-table value was 2.26 and the t-count value was 3.26, which is greater than 2.26, indicating a significant improvement in agility. Similarly, for speed, the t-test analysis showed that the t-count value was 3.04, which was also greater than the t-table value of 2.26, confirming a significant improvement in speed. Although the improvement in agility (0.24 seconds) was greater than the improvement in speed (0.07 seconds), both metrics showed a significant positive effect from the holistic training approach. Conclusion: The holistic training method significantly improved both agility and speed in tennis athletes at Club Nusalima. Agility improved from an average of 2.81 seconds to 2.74 seconds, and speed also showed measurable improvement from 3.04 seconds to 2.96 seconds. These findings suggest that the holistic approach is an effective model for enhancing physical performance in tennis players.

Abstract. Sports psychology plays a vital role in improving the performance of badminton athletes. Psychological factors such as motivation, competitive anxiety, concentration, and mental resilience have been identified as critical influences on athlete performance. This study aims to systematically review the existing literature to identify and analyze the role of sports psychology in improving badminton athlete performance. The researcher searched for journal articles, books, and research reports relevant to sports psychology and badminton from various electronic databases through a systematic literature review approach. Specific inclusion criteria were applied to select studies that explicitly addressed the effect of psychological interventions on the performance of badminton athletes. Data analysis was conducted qualitatively to synthesize findings from the literature chosen. The literature review revealed that psychological techniques, including goal setting, relaxation techniques, visualization, and mental toughness coaching, positively impact the performance of badminton athletes. Findings suggest that psychological training integrated into athlete training programs can increase motivation, reduce competitive anxiety, strengthen concentration, and build mental resilience, all critical factors in athletic achievement. Sports psychology is a critical element in the training of badminton athletes, with significant potential to improve athlete performance. Psychological interventions tailored to the individual needs of athletes hold promise in optimizing athletic potential and achieving competitive success. Future research is needed to understand better how to best integrate these psychological techniques into the training of badminton athletes and to design more effective training programs that take full advantage of the role of sports psychology.

Un grupo vulnerable de padecer enfermedades cardiovasculares podrían ser los estudiantes universitarios, ya que la transición de la educación media a la superior modifica sus estilos de vida. El objetivo del presente estudio fue establecer los estilos de vida y riesgo cardiovascular a partir de indicadores antropométricos en estudiantes universitarios. La investigación fue de tipo transversal, descriptivo y observacional. Se recogió información sobre los antecedentes patológicos familiares y estilos de vida, como la ingesta de alcohol, consumo de cigarrillos y practica de deporte o ejercicio físico y consumo de alimentos. Además, se tomó el peso, talla y circunferencias de la cintura y cadera. El riesgo cardiovascular se estableció mediante los puntos de corte de la circunferencia cintura, índice cintura/altura e índice cintura cadera. Como resultado se reflejó, que el mayor porcentaje de investigados tanto varones como mujeres, no consumen bebidas alcohólicas (62,9%), ni cigarrillo (92,3%) y no realizan ningún tipo de actividad física (58,8%). En cuanto al consumo de alimentos, se reportó una ingesta insuficiente de frutas (76,6%), verduras y hortalizas (71,1%), no obstante, existió una ingesta elevada de comidas rápidas, snack y bebidas gaseosas. Finalmente, el riesgo cardiovascular medido a través de los indicadores antropométricos fue muy bajo. A pesar de que el riesgo cardiovascular fue bajo en los estudiantes universitarios investigados, se observaron estilos de vida inadecuados, como la ingesta excesiva de alimentos hipercalóricos y sumado al sedentarismo, podrían constituir un factor de riesgo para el desarrollo de enfermedades cardiovasculares a largo plazo.

Published: October 2024

One of the important aspects of improving the effectiveness of training qualified divers is understanding the peculiarities of body component composition and the state of microcirculation. The aim of this study was to investigate the component body composition and microcirculation peculiarities of qualified divers diving from different types of gymnastic equipment. The study sample included 30 qualified divers, consisting of 17 girls and 13 boys aged 13 to 18 years. Body composition was assessed using bioimpedance analysis, and the functional state of the microcirculatory system was evaluated through laser Doppler flowmetry. The results indicated that divers who utilized the 10-meter tower exhibited a statistically significant decrease in adipose tissue content and an increase in fat-free mass and relative muscle mass compared to athletes in other diving disciplines. Additionally, a high level of tissue perfusion and microvascular reactivity was observed among the athletes. These findings are crucial for assessing and enhancing the training effectiveness of qualified diving athletes.

Published: October 2024

Ischemic heart disease continues to be a major cause of morbidity and mortality around the world. Nowadays, research is focusing on the role of the brain-heart axis in autonomic nervous system balance. Resting heart rate variability (HRV) could help to identify the readiness of ischemic patients to achieve cardiac rehabilitation exercise stimulus in a safer manner. The objectives of the study were i) to analyze the resting HRV in ischemic cardiopathy, determining whether it was below or within its normal range, and ii) to identify the effect of the psychophysiological parameters of age, body mass index (BMI), blood pressure, cardiorespiratory fitness, and quality of life. This was a cross-sectional study of patients affected by ischemic cardiopathy. The patients were divided into the nonNormal-HRV or Normal-HRV group according to their normal resting HRV. The HRV temporal and frequency domains were recorded along with heart rate and blood pressure, BMI, cardiorespiratory fitness and auto-perception. The sample comprised men with an average age of 58.64±9.54 years. In total, 43.92% were below their normal resting-HRV range. They were older (P<.001, d=.856), had worse auto-perception (P<.001, d=.473), and higher systolic and lower diastolic blood pressure (P<.001, d=.446; P=.007, d=.29). HRV domains correlated directly (P<.05) with diastolic blood pressure and inversely with heart rate and age. The percentage of low resting-HRV scores in ischemic patients was higher than expected and was conditioned by age, blood pressure and heart rate. Moreover, the patients had worse auto-perception. All these factors should be considered to optimize cardiac rehabilitation programs.

Published: October 2024

Purpose: Ubiquitous disruptive innovations and technologies, frequently changing consumer behaviour, and evolving market dynamics in Kenya, have compelled television stations to constantly explore innovative ways to achieve long term business sustainability. Firms must be ambidextrous; balancing the tensions of excelling in current businesses while exploring opportunities for future growth. This requires top leadership teams that are well suited to the challenge of steering organisations in disrupted business contexts. This paper investigated the effect of top management team characteristics on the linkage of strategic agility and sustainable competitive advantage of licensed television stations in Kenya.
Methodology: A descriptive cross-sectional survey was employed and primary data was collected using a semi-structured questionnaire. Data from 210 licensed television stations that were operational at the time of the study was analysed using structural equation modelling (SEM).
Findings: The results of the study indicated that strategic agility had a positive and significant effect on sustainable competitive advantage of licensed television stations in Kenya. Further, top management team characteristics were a mediator on the nexus  between strategic agility and sustainable competitive advantage, as well as a predictor variable of sustainable competitive advantage of licensed television firms in Kenya.
Unique Contribution to Theory, Practice and Policy: The research was underpinned by the dynamic capabilities, resource-based view and upper echelons theories. The implication is that, to achieve sustainable competitive advantage, it is crucial for the top management team to possess specific attributes, including a balanced mix of both young and experienced members, diversity in functional backgrounds (especially those with knowledge of disruptive technologies and innovations), varying educational levels, and a mix of long-tenured and new managers.

Published: October 2024

The Malaysian construction industry plays a crucial role in generating national wealth. To realize the vision of Malaysia as a well-developed nation, adopting technologies and innovations is critical for the industry, particularly as the country advances towards the Fourth Industrial Revolution (IR 4.0). Building Information Modelling (BIM) is one such process, supported by various tools, that significantly enhances construction project efficiency while easing the workload of industry professionals. As integral construction team members, quantity surveyors are poised to benefit from BIM in improving their cost estimation and planning processes. However, various challenges and barriers have hindered the full implementation of this innovation. The focus of this paper is to identify the barriers to BIM implementation within the northern region of Malaysia, a topic that has become increasingly relevant as Malaysia moves towards the Fourth Industrial Revolution (IR 4.0). Data collected from a survey of 22 QS firms revealed that the top two barriers are the high cost of operating BIM software and the high cost of training. Based on these findings, it is recommended that the government provide incentives to encourage QS consultants to invest in BIM technology.

Published: October 2024

Bamboo fibres are one of the sustainable lignocellulosic resources explored for polymer composites in recent years. Research has shown that bamboo fibres have the potential to be used in a variety of critical applications. Nevertheless, bamboo fibres are susceptible to thermal and hygroscopic loads, and their mechanical properties are limited by the unequal interfacial strength and varying fibre dimensions. Implementing hybrid procedures or incorporating alternative materials, such as aluminium metal, is strongly advised to address this issue. Thus, this study investigates the tensile and flexural performances of the hybrid bamboo fibre/aluminium expanded mesh-reinforced polymer composites. The composites were fabricated using epoxy resin reinforced with bamboo fibre, and an aluminium expanded mesh sheet was constructed using a vacuum infusion process utilising various stacking sequences and mesh sizes. The test findings indicated that the composite material exhibited tensile stress values ranging from 27 to 34 MPa and a corresponding tensile strain value between 1.1% and 1.6%. The flexural strength and strain values were measured within the range of 44 Mpa to 59 Mpa and 2.2% to 3.2%, respectively. ANOVA analysis showed that both stacking sequences and mesh size significantly affected the tensile performances of the composites, while only stacking sequences affected the flexural performance significantly. Overall, a hybrid composite of bamboo fibre and aluminium mesh is well-suited as a substitute material in industries requiring exceptional mechanical properties.

Published: October 2024

Hybrid fibers are an interesting addition to reinforce geopolymer-based composites due to their advantages over single-fiber reinforcement. The performance of hybrid fibers is dependent on the fibers' composition, type, properties, length, and volume fraction. Therefore, this review discusses the state-of-the-art hybrid fiber-reinforced geopolymer composites (HFRGC) through two approaches: scientometric analysis and conventional review of HFRGC based on data extracted from Scopus from 2013 until 2023. The scientometric analysis was carried out by adopting VOS Viewer software and focuses on the annual publication of documents, top publication sources, co-occurrence keywords, researchers, top-cited papers, and countries. In contrast, the desk study refers to experimental data on the fresh properties and compressive, tensile, and flexural properties of HFRGC. This review output aids researchers in networking, promoting cooperative research, exchanging ideas, and creating joint ventures among researchers of HFRGC worldwide. The performance of HFRGC obtained from the desk study showed the potential of HFRGC as an option for a greener composite that will benefit the construction industry.

Published: October 2024

Bamboo is increasingly used as an alternative material for producing renewable and environmentally friendly products. Bamboo should be dried before use to increase its stability and improve its resistance against biodeterioration agents. The most common drying method for bamboo is through air-drying. Alternatively, artificial drying, such as solar drying, can produce optimum drying results regarding the drying rate and quality of bamboo throughput. This study investigated the potential utilisation of solar drying methods for processing local bamboo. The drying characteristics and physical and mechanical properties of solar-dried Gigantochloa levis bamboo culms’ bottom, middle, and top sections were determined. The drying time of G. levis culm has been reduced to about 40 days compared to the conventional air drying of 70 days using the solar-assisted kiln dryer. Solar-dried culms have a lower final moisture content of 20% than air-dried ones. The average circumference and diameter shrinkage values of solar-dried G. levis culms from green to approximately 12% moisture content were 3.22% and 4.29%, respectively, and the wall thickness shrinkage was 8.12%. The mean values of modulus of rupture and modulus of elasticity of solar-dried G. levis culm were 63.75 and 12567.99 N mm-2, respectively, while its mean values of compression and shear parallel to fibre were 45.87 and 10.01 N mm-2, respectively. The quality of solar-dried G. levis culms produced in this study showed the viability of using a solar-assisted kiln-dryer as a potential alternative processing method for drying local bamboo species in Malaysia.
Raiders of the Sultan in the Theater of Plunder: Tribes and Raiding in Ottoman-Iranian Rivalries
Authors: Çiftçi Erdal
Published: October 2024

Existing scholarship in Ottoman studies often portrays the tribes in the Ottoman- Iranian borderlands as isolated troublemakers in an area characterized by turbulence and banditry, disrupting relations between empires and straining diplomatic ties. This study argues that this perspective underestimates the tribes’ interconnectedness with imperial policymaking, particularly how nomadic mobility was instrumentalized as a military asset by both states. Empires frequently militarized and empowered these tribes to align them with their interests, accommodating their cross-border movements and utilizing them as raiders. To illustrate the hegemonic relationship between tribes and state officials, this study delves into and juxtaposes the Ottoman-Iranian wars of 1578–1590 and 1821–1823, periods wherein tribes were overtly enlisted as auxiliary forces alongside regular armies. Raiding emerged as one of the central tactics in these conflicts, transforming the imperial borders into a theater of plunder. The study also reveals how petty raids endured as a means of micro-level territorial assertion among tribes amidst ongoing rivalries between empires, with tribes often functioningas proxies backed by local authorities. The turbulent, nomadic nature of these tribes cannot be attributed solely to their inherent traits, as it is apparent that imperial policies facilitated their role as raiders.
Some Intensive Adjectives with p in the Two Tuvan Dialects Jungar Tuvan and Uriankhai
Authors: Li Yong-Sŏng
Published: October 2024

Tuvan belongs to the adaq-group of Turkic languages. Tuvan and its related varieties can be collectively referred to as so-called “Sayan-Turkic.” As a result of this study, based on data obtained from field studies on “Sayan-Turkic” conducted by the Altaic Society of Korea in 2004, 2005, and 2006, it was possible to detect some intensive adjectives with p in Jungar Tuvan and Uriankhai. The questionnaires used did not have vocabulary items designed to search for intensive adjectives. If those vocabulary items had existed, there would have been an opportunity to systematically check intensive adjectives from all informants. The intensive adjectives obtained, especially in Jungar Tuvan and Uriankhai, can be said to be quite important in their own right. There will be many examples like this in the various Turkic language materials obtained from two research projects carried out by the Altaic Society of Korea over a period of six years (three years each). These materials, which have been neglected for over 10 years, must be properly processed as quickly as possible.

Published: October 2024

High blood pressure is the most common chronic medical problem prompting visits to Community health care providers in US (80%) and India (25% rural and 33% urban). There has been an alarming increase in the hypertension burden worldwide. Antihypertensive drugs and lifestyle modifications including exercises remains mainstay of treatment. This study aimed to determine effect of alternate nostril breathing on blood pressure among hypertensive patients. It was a quasi-experimental study employing a pre-test post-test control group design. Sixty purposively selected participants were randomly allocated into experimental and control groups (30 each). Blood pressure was measured using a calibrated digital sphygmomanometer. The experimental group received an intervention of ANB, administered twice daily for 10 minutes over 15 days. Both the groups continued their hypertension medication throughout the study. Systolic and diastolic blood pressure readings were taken on day 1 (baseline) and day 15 (post-test). The majority of participants were females and over 60 years of age. A significant decrease in both systolic and diastolic blood pressure was observed in the experimental group, which was statistically significant (p<0.001). Control group also showed significant difference in both systolic and diastolic readings from day 1 to day 15 (p<0.001), likely due to ongoing hypertension medication. To conclude, alternate breathing exercise was effective in reducing both systolic and diastolic blood pressure.

The second wave of COVID 19 struck in March-April 2021, and it proved to be more severe than the first, with significantly higher cases and mortality rates worldwide. This study aimed to assess anxiety, sleep quality, and coping strategies among Health Care Workers (HCWs) engaged in the care of COVID-19 patients during the second wave of the pandemic at tertiary care hospitals in Central India. It was a retrospective crosssectional web-based survey conducted among HCWs at a tertiary care hospital in central India during the second wave of COVID-19, utilising a convenience sampling method via Google Forms. The survey assessed anxiety, depression, sleep quality, and coping strategies using the Hospital Anxiety and Depression Scale (HADS) and the Pittsburgh Sleep Quality Index (PSQI), along with a self-structured 4-point Likert scale. Data was collected from August to September 2021, with 114 HCWs. Ethical approval was obtained, and data were analysed using SPSS version 24, employing descriptive and inferential statistics, including Chi-square tests for associations, with significance set at p < 0.05. Approximately 38.6 percent of HCWs experienced borderline abnormal anxiety, while 31.6 percent reported borderline abnormal depression. Most (57%) exhibited poor coping skills, and all participants reported poor sleep quality. Significant associations were found between anxiety and marital status (χ²=11.994, p=0.017) as well as living conditions (χ²=12.101, p=0.002). To conclude, enhancing coping mechanisms and sleep quality is crucial for reducing anxiety and depression among HCWs. Providing them with more time to connect with friends and family may also improve their overall well-being and resilience.

Every year, 15 million pre-term and/or about 21 million low birth weight newborns appear worldwide who form the vulnerable population and need high quality care due to neglect of breastfeeding, which is a basic requirement as much for infant survival as for their normal growth and development. The World Health Organisation (WHO) recommends exclusive breastfeeding up to 6 months and thereafter with complementary feeding up to 2 years of age or longer. Covid-19 era, with far reaching impacts on health, economy and life style, has been very dreaded period in our lives. An unpredictable fear loomed large on health functionaries in particular. Lockdowns impacted maternal experiences and breastfeeding practices. The new scenario, with potential risk of transmission necessitated better infant feeding support in view of mental health challenges and unknown circumstances faced by mothers towards self-care and infant care. This study to assess the impact of Covid-19 on neonatal feeding practices of post-natal mothers was part of a TNAI-funded project. Survey type research approach was adopted in this retrospective cross-sectional design study using google forms from mothers across the country through different social platforms and lactation groups. The study participants also included the mothers visiting a tertiary super specialty hospital in Southern India as the obtained responses through google forms were not meeting the sample size estimated. Post-natal mothers who delivered during the Covid-19 pandemic in India since March 2020 constituted study population. A total of 382 samples were included in the study.
Manifestations of sulfuric acid speleogenesis in the Mulapampa travertine, Central Andes of Peru: evidence from the Gruta con Lago

Published: October 2024

Sulfuric acid speleogenesis (SAS) is a form of hypogene speleogenesis characterized by the formation of caves in carbonate rocks due to the presence of sulfuric acid. This study focuses on the Gruta con Lago, one of three caves identified in the Mulapampa travertine, located in the central Andes of Peru. These caves are accessed through collapse sinkholes, and much of their morphology results from roof breakdown. The bottom of the studied cave is situated at the current water table. Despite the absence of typical solutional features associated with SAS caves, mineralogical and geochemical evidence of speleogenesis involving H2SO4 has been found in Gruta con Lago. Significant accumulations of gypsum deposits on the cave floor and replacement gypsum crusts on walls – both considered by-products of SAS – are present. Cave gypsum samples exhibit negative sulfur isotopic composition (ranging from -19.4 to -8.2‰) and oxygen (ranging from -9.0 to -1.3‰), which are indicative of sulfide (H2S) oxidation. This article discusses potential scenarios of SAS events in the evolution of hypogene karst in the Mulapampa travertine. It also considers the significance of the proximity of the active volcanoes of the Ampato-Sabancaya Volcanic Complex (ASVC) and seismogenic crustal faults in the formation of a thick travertine cover and the potential for SAS processes.

Glioblastomas are the most common and aggressive form of malignant primary brain tumors in adults. The standard treatment is surgical resection followed by radiotherapy and chemotherapy. Despite optimal treatment methods, the prognosis for patients remains poor.
Preoperative determination of glioblastoma margins remains beneficial for the complete removal of the tumor mass. Radiotherapy is essential for post-surgery treatment, but radioresistance is a significant challenge contributing to high mortality rates. Advanced imaging technologies are used to analyze the changes in the peritumoral brain zone (PTZ). Consequently, they may lead to the development of novel therapeutic options, especially targeting the marginal parts of a tumor, which could improve the prognosis of glioblastoma patients.
The clinical presentation of glioblastoma is heterogeneous and mostly depends on the location and size of a tumor. Glioblastomas are characterized by both intratumoral cellular heterogeneity and an extensive, diffuse infiltration into the normal tissue bordering a tumor called the PTZ. Neuroimaging techniques, such as diffusion-weighted imaging (DWI), diffusion tensor imaging (DTI), perfusion-weighted imaging (PWI), proton magnetic resonance spectroscopy (1H MRS), and chemical exchange saturation transfer (CEST) are useful methods in the evaluation of the tumor infiltration and thus the resection margin.
Assessment of thyroid nodule risk stratification knowledge and utilization among Polish physicians: a pilot study
Authors: Janicki Lukasz , Patel Agastya , Nowicki Tomasz , Hellmann Andrzej
Published: October 2024

Purpose

Ultrasonography is the primary diagnostic tool for evaluating thyroid nodules. The Thyroid Imaging Reporting & Data System (TIRADS) aims to standardise assessment and reduce fine-needle aspiration biopsies through risk stratification. This pilot study examined knowledge and utilisation of TIRADS among Polish physicians, their perception of the usefulness of TIRADS application and the extent of knowledge of individual nodule features included.

Material and methods

An internet-based questionnaire about TIRADS use in clinical practice was sent out to Polish Ultrasound Society members. Information on the responder’s experience with thyroid ultrasound and knowledge and use of TIRADS was assessed and analysed.

Results

Out of 159 physicians, 66.6% did not use TIRADS despite 43.4% being aware of its existence. EU-TIRADS was the most commonly adopted classification (50.9%). Participants who adopted TIRADS were younger (p = 0.047) and more likely to be radiologists (p < 0.01). TIRADS use was more prevalent in university clinical hospitals (p = 0.02), among physicians doing thyroid ultrasound as their primary professional activity (p < 0.01), those performing > 100 thyroid ultrasound examinations per year (p < 0.01) and those involved with thyroid fine-needle aspiration biopsy (p < 0.01). The purposes of TIRADS adoption (p < 0.01) and included imaging features (p < 0.01) were more accurately recognized by TIRADS users.

Conclusions

TIRADS utilization among Polish clinicians is limited, despite awareness of the classification’s existence. Knowledge of TIRADS components and the purpose of its application among users is satisfactory. Further training and TIRADS adoption should be encouraged, especially in the light of the recent EU-TIRADS-PL guidelines recom­mended by the Polish Scientific Societies.

Published: October 2024

This paper aimed to apply the Goal Programming approach to optimize important parameters in the production and inventory management processes of tissue papers and paper towel manufacturing. A real-life scenario problem was formulated and solved, and a sensitivity analysis was conducted to examine the effects of changes in goal priorities and target values. The goal programming solution optimized the company’s profit while meeting the demand and also minimizing raw material and labor usage. The results show the optimal inventory levels for the four products as determined by market demand in the target month to be: I1* = 215 tons (SSTP), I2* = 380 tons (MSTP), I3* = 550 tons (JSTP), and I4* = 275 tons (PT). The sensitivity analysis reveals that changes in goal priorities and target values have significant effects on optimal production and inventory levels, thereby highlighting the importance of careful goal setting and prioritization. The findings from the research revealed that a 50-tonne increase in production will increase the profit margin by ten percent for jumbo-size toilet paper. The proper understanding of the production implications will enable the mill to optimize its production, manage resources, and also maximize profit.
