The Theoretical Gap in the Study of New Quality Productive Forces and the Economic Analytical Perspective of “Heterogeneity”
Authors: He Jun
Published: December 2024

Economic studies on the new quality productive forces NQPF are mushrooming, however, on the whole, the majority of existing studies primarily focus on revealing and summarizing the economic laws guiding the development of NQPF based on the“general”characteristics of individual organizations at the microlevel and institutions at the macro level. This paper argues that the background of “getting great” and the competition scenario between countries determine that “heterogeneity” is the most relevant and theoretically challenging issue in the NQPF, and also the most likely to yield significant academic outcomes. In view of the fact that the existing problem setting, conceptual framework, and analytical tools of existing eccomics fail to effectively address the unique prescriptive phenomena of NQPF, including direct competition between countries, power countries, and heterogeneity, future academic research on new quality productive forces should go beyond the current “general” issues orientation, directly address the extreme phenomena and problems in the “genesis” stage in the latest round of scientific and technological revolution, and strive to push forward the frontiers of theoretical research.
Functional Upgrading of Value Chains and the Carbon Emissions Reduction Embodied in China’s Exports: From the Perspective of the Improvement in the FDI Quality
Authors: Chen Fuzhong , Luo Ke , Dong Kangyin
Published: December 2024

Improving the quality of foreign investment to help functional upgrading of the value chain is an important starting point for China’s manufacturing industry to achieve low-carbon and high-quality development. Based on the data of the functional activities of each manufacturing greenfield investment project in China from 2003 to 2018, this paper constructs specialization index of the upstream and downstream functional division of labor of value chains, and theoretically explains and empirically tests the impact and mechanism of the functional upgrading of the value chain driven by the improvement of foreign investment quality on the embodied emissions in China’s export trade. The results show that the functional upgrading of the value chain can significantly reduce the embodied emissions in China’s export trade. The mechanism analysis shows that the functional upgrading of the value chain driven by the improvement of the quality of foreign investment mainly plays a role in reducing the embodied emissions in China’s export trade through the optimization effect of factor structure, the effect of human capital accumulation and the effect of service demand creation. Extended analysis finds that high-quality foreign investment engaged in upstream functional activities and inflows into eastern China have more obvious inhibitory effects on the embodied emissions in export trade. At the same time, the functional upgrading of the value chain is more conducive to reducing the embodied emissions in export trade in pollution-intensive manufacturing industries. This paper verifies the “pollution halo” effect of high-quality foreign investment, and provides strong support for China to attract and utilize foreign investment more vigorously and promote high-level opening up under the new situation.

Authors: Mahadevan Venkatramani , Karuppiah Abirami , Venkatraman Shravan
Published: December 2024

Objectives

Acute myocardial infarction is a critical medical condition that poses a significant risk to life. It is distinguished by the abrupt cessation of blood flow to a specific segment of the cardiac muscle. Acute myocardial infarction accounts for more than 15 % of global mortality annually.

Methods and Results

A total of 433 young patients admitted with acute coronary syndrome – myocardial infarction underwent thrombolysis with fibrin specific agents followed by underwent diagnostic coronary angiogram between 01.09.2021 and 31.10.2022. The odds ratio showed a value of 1.973, which is much higher than the individuals with diabetes (0.306). Young individuals (25.9 %) with hypertension have a greater chance of recovery by thrombolysis.

Conclusions

The factors that contribute for the myocardial infarction should be recognized and addressed. Recognizing and addressing these risk factors through education, lifestyle modifications, and early intervention are crucial for preventing myocardial infarction and promoting good health.
Differentiated thyroid cancer in adolescents – does extent of disease at presentation differ with age?
Authors: Arya Priya , Wright Emily A. , Shaw Eric K. , Lubin Daniel J. , Prickett Kara K.
Published: December 2024

Objectives

The authors sought to assess whether the age of 18 reflects a true pathological inflection point that justifies transitioning between pediatric and adult paradigms of care with differentiated thyroid cancer (DTC).

Methods

A retrospective chart review was conducted for patients aged 12–24 undergoing hemithyroidectomy or total thyroidectomy for papillary or follicular thyroid carcinoma from 2010 to 2020.

Results

A total of 153 patients receiving surgery for DTC were assessed for pathological stage, nodal metastasis, and thyroid neoplasm characteristics. When comparing pathologic tumor staging of patients <18 vs. ≥18 years old, there was a significant relationship between age and pT stage (p=0.009), but not between age and pN stage (p=0.319). However, when comparing patients ≤15 vs. >15 years, there was a significant relationship between age and pT stage (p=0.015) and age and pN stage (p=0.016). Patients ≤15 years of age most commonly had stage pT2 tumors (48.9 %, n=22), whereas most >15 years had stage pT1 tumors (37.9 %, n=41). Of patients whose lymph nodes were analyzed, patients ≤15 years were most likely to have pN1b disease (31.1 %, n=14), while patients >15 years were most likely to have pN0 disease (33.3 %, n=36).

Conclusions

In this sample, separating children and adults at an age of 15, rather than 18, yielded more significant differences in risk of nodal involvement. Markers of invasive histology were more common in patients older than 15, while nodal involvement was more common in patients 15 and under.
Pediatric Graves’ disease in Argentina: analyzing treatment strategies and outcomes
Authors: Rothenfusser Anna , Chiesa Ana , Papendieck Patricia
Published: December 2024

Objectives

Graves’ disease is the leading cause of hyperthyroidism in children. Only a small percentage of pediatric patients achieve remission with anti-thyroid drug treatment (ATD), and both definitive therapies (thyroidectomy, or radioiodine thyroid ablation) cause lifelong hypothyroidism. Our objective was to evaluate the outcome of patients with pediatric Graves’ disease (PGD), treated at a single tertiary center, focusing on response to medical treatment, remission rate, adverse reactions (AR), definitive treatment (DT), and potential predictive factors for remission.

Methods

Data from clinical charts of 130 patients diagnosed with PGD between 2006 and 2021 were collected: epidemiological, clinical, biochemical characteristics, outcome, remission, adverse reactions (AR), and DT were registered. Predictive factors at diagnosis were evaluated for 88 patients diagnosed at our center.

Results

Our patients were 78 % female, 98 % Hispanic, with a median age of 12.7 years (range 1.7–17.3 years). Fourteen (11 %) had Down syndrome. Severe thyrotoxicosis (FT4>5.5 ng/dL) was seen at diagnosis in 66 %. Initially, 129/130 received ATD; during the study, 17 participants (13 %) reached remission, with a median ATD duration of 3.1 years (range 1.3–6.1 years). The chance of remaining hyperthyroid was 65 %. Only one patient relapsed 1.3 years post-ATD. Forty-six percent (59/129) needed DT, 31 % (40/129) were lost to follow-up, and 10 % (11/129) remained on ATD. AR affected 26 % of the patients and most (74 %) occurred within the first 3 months, half of them severe enough to discontinue ATD. No significant predictive factors were identified.

Results

ATD, our first-line treatment, resulted in low remission rates for Hispanic pediatric patients with severe thyrotoxicosis at diagnosis. Poor adherence issues contributed to the indication of DT (46 %) and loss to follow-up (31 %) during the studied period. Based on our findings, DT should be considered at 4 years of ATD in persisting PGD.

Conclusions

ATD, our first line treatment, resulted in low remission rates for Hispanic pediatric patients with severe thyrotoxicosis at diagnosis. Poor adherence issues contributed to the indication of DT (46 %) and loss to follow-up (31 %) during the studied period. Based on our findings, DT should be considered at 4 years of ATD in persisting PGD.
Numerical modelling of creep, agin and leakage of the prestressed reinforced concrete structure. Application to concrete containment building

Published: December 2024

The concrete containment building (CCB) is the third and last safety barrier to protect the environment from diffusion of radioactive products. In 2014, Électricité de France (EDF) launched the VERCORS project to improve the knowledge of leak-tightness in the CCB under air pressure loading and aging effects. VERCORS is in a 1:3 scaled CCB mock-up of a 1,300 MWe French pressurized water reactor (PWR). This paper presents a numerical methodology applied on VERCORS mock-up and numerical results focus on the gusset only, which is the lower part of the containment wall casted right after the base slab. Concrete is modeled through 3D elements while rebars and tendons are modeled by 1D elements. The simulation includes THM analysis of the gusset, prestressing phase and pressurization phase, and is conducted through a finite element code, Cast3M. The delayed strains including creep and shrinkage are especially considered. The instantaneous prestress losses, which result from friction; relaxation and pull-in at wedge, are taken into account. Regarding the long-term prestress loss due to the delayed strains, it is achieved by a kinematic relationship at interface of concrete-tendons. To describe cracks in concrete, an elastic damage model is used for the concrete elements, and the post-processing of leak-tightness is based on through crack leakage only. Those cracks appear usually at the early age phase given the restrained strains that the gusset undergoes during the hydration and hardening phase.

)O8 plagioclase feldspars is synthesized perfoming the solid-state method, where the endmembers are the anorthite (CaAl2Si2O8) and albite (NaAlSi3O8). The bulk chemical composition, particularly the Al/Si ratio, of each member is determined from energy-dispersive X-ray spectroscopy, which is supported by X-ray powder diffraction data Rietveld refinements. Selective plagioclase members (x = 0.0, 0.4 and 1.0) are mechanically weathered using high-energy ball milling, leading to significant changes of microstructural features such as average crystallite size and micro-strain. Total scattering data are collected using in-house X-ray facilities and analyzed by pair distribution function refinements. The vibrational modes of the samples are evaluated by Raman spectroscopy, complementing the local structural description.
A New Insight into the Role of CART Peptide in Serotonergic Function and Anxiety
Authors: Balasubramanian Nagalakshmi , Wang Ruixiang , Ismail Shafa , Hartman Benjamin , Aboushaar Zeid , Marcinkiewcz Catherine A.
Published: December 2024

Cocaine- and amphetamine-regulated transcript (CART) peptide has been implicated in stress-related behaviors that are regulated by central serotonergic (5-HT) systems in the dorsal raphe nucleus (DRN). Here, we aimed to investigate the interaction between CART and DRN 5-HTergic systems after initially observing CART axonal terminals in the DRN. We found that microinfusion of CART peptide(55–102)into the DRN-induced anxiogenic effects in male C57BL/6J mice, while central administration of CART reduced c-Fos in 5-HTDRNneurons. This inhibitory effect of exogenous CART on 5-HTDRNactivity and local 5-HT release was also demonstrated via in vivo fiber photometry coupled with calcium and 5-HT biosensors. CART inputs to the DRN were observed in various subcortical nuclei, but only those in the centrally projecting Edinger–Westphal nucleus (EWcp) were highly responsive to stress. Chemogenetic activation of these DRN-projecting CARTEWcpneurons recapitulated the effects of intra-DRN CART infusion on anxiety-like behavior in males, but not in females, suggesting a sex-specific role for this pathway. Interestingly, CARTEWcpprojections to the DRN made direct synaptic contact primarily with non-5-HT neurons, which were also found to express putative CART receptors. Furthermore, chemogenetic stimulation of this CARTEWcp→DRNpathway inhibited 5-HT neurons while increasing activity in local GABAergic neurons. In summary, this study establishes for the first time a neuromodulatory role for CARTEWcpneurons in 5-HTDRNneurotransmission and suggests that CART may drive anxiety-like behavior by promoting feedforward inhibition of 5-HT neurons.

Published: December 2024

The structure and function of the brain and cardiovascular system change over the lifespan. In this study, we aim to establish the extent to which age-related changes in these two vital organs are linked. Utilizing normative models and data from the UK Biobank, we estimate biological ages for the brain and heart for 2,904 middle-aged and older healthy adults, including both males and females. Biological ages were based on multiple structural, morphological, and functional features derived from brain and cardiovascular imaging modalities. We find that cardiovascular aging, particularly aging of its functional capacity and physiology, is selectively associated with the aging of specific brain networks, including the salience, default mode, and somatomotor networks as well as the subcortex. Our work provides unique insight into brain–heart relationships and may facilitate an improved understanding of the increased co-occurrence of brain and heart diseases in aging.

Authors: Yuan Mingqian , Xu Dongmei
Published: December 2024

Recent decades have witnessed growing attention to child reading education, but research on reading teacher training remains scarce, constituting an impediment to the further advancement of reading instruction. This study seeks to explore the paths to improving reading teachers’ professional competence via structured training, using Qinjinmuyu’s “Reading Teacher Professional Competence Certification” program as an example. Based on Qinjinmuyu’s reading teacher professional competence framework, the program developed a training pattern with the four major procedures: reading training, reading instruction knowledge training, reading instruction practice, and assessment. The program’s effects were also examined through questionnaires and interviews. The results reveal that the teachers who successfully completed the training course made significant progress in their knowledge of child literacy, reading curriculum design, and reading instruction techniques.
Contener y regular. Nacimiento del desregulado emocional en la educación chilena
Authors: Palacios Díaz Diego , Bonhomme Manríquez Alfonso , Báez Oyanedel Teresa
Published: December 2024

Este artículo analiza discursivamente el nacimiento del sujeto desregulado emocionalmente en el período enunciativo contemporáneo de la educación chilena. Desde el marco conceptual de los procesos de emocionalización y terapización que acontecen en las sociedades neoliberales, se desarrolla un análisis foucaultiano de discurso con miras a indagar en problematizaciones, tecnologías y posiciones de sujeto que configuran el objeto de estudio. El nacimiento de una monstruosidad, el desregulado emocional, responde a un poder del detalle que articula, minuciosa e insidiosamente, diversas relaciones, tecnologías y prácticas para contenerlo y regularlo. El sueño político de una escuela neoliberal hipercontrolada se construye a partir de diversas regulaciones que apuestan por evitar los peligros que plantea el sujeto desregulado a sus fines productivos. Esto es discutido desde la necesidad de articular formas liberadoras de sujeto y subjetividad en las escuelas chilenas.
Exercise addiction in individuals who exercise regularly
Authors: Tüzer Bekir Furkan , Demirel Havva
Published: December 2024

Background and Study Aim. Addiction has significant effects on individuals who exercise regularly, influenced by factors such as age and gender. This study aimed to measure the exercise addiction levels among university students who regularly engage in fitness activities.
Material and Methods. The Exercise Addiction Scale was used to determine the participants' levels of exercise addiction. This scale was administered to 198 voluntary participants (students), including 101 women and 97 men. A demographic information form was used to collect data regarding participants' gender, age, years of training, and levels of national athleticism. To compare differences between two independent groups, independent t-tests and One-Way ANOVA multiple comparison tests were applied to identify differences between variables.
Results. Results revealed significant differences in the tolerance development and passion subscales based on gender, with results favoring women. No statistically significant difference was found in the subdimension of excessive focus and mood changes based on years of athletic experience. In contrast, individuals with 1-3 years of experience had significantly higher scores in the postponement of individual-social needs compared to those with 4-6 years of experience. In the subdimension of tolerance development and passion, individuals with 1-3 years of experience scored significantly higher than those with 4-6 years and those with 11 or more years of experience. However, no significant differences in exercise addiction scores were observed based on age or national athlete status.
Conclusions. Results suggest that the risk of exercise addiction may be mitigated by fostering a balanced approach to sports participation. Emphasizing both health and social engagement, rather than solely performance, may help individuals maintain a healthier relationship with exercise.

Authors: Zadarko-Domaradzka Maria , Nizioł-Babiarz Edyta , Barabasz Zbigniew , Zadarko Emilian
Published: December 2024

Background and Study Aim. Physical activity (PA) has become a critical component of social, economic, and health policy worldwide. Leisure-time physical activity (LTPA) plays a particularly significant role in preventing lifestyle-related diseases. This study aimed to analyze students' LTPA and examine the relationship between LTPA levels and somatotype.
Material and Methods. The study included 309 students, aged 20–24, from five Polish universities. Anthropometric measurements were taken, somatotypes were determined using the Heath-Carter method, and LTPA was assessed using the Minnesota Leisure-Time Physical Activity Questionnaire (MLTPAQ).
Results. Among the students studied, 22.3% had a BMI above the normal range—31% of males and 13.6% of females. Men reported higher levels of LTPA than women and engaged in more physical activity across all intensity levels. In both male and female groups, one in four students did not reach the recommended leisure-time physical activity level of 1000 kcal/week. A statistically significant negative correlation was found between endomorphy and high-intensity LTPA in both sexes. Additionally, one in four Polish students in the study did not achieve a level of leisure-time physical activity sufficient to meet health-protective energy expenditure guidelines.
Conclusions. These findings underscore the essential role of high-intensity exercise in achieving beneficial levels of leisure-time physical activity (LTPA). They also highlight the importance of considering individual somatotype characteristics when developing physical activity recommendations for university students. Promoting tailored, intensity-specific LTPA programs could enhance engagement and address diverse fitness needs, contributing to effective health interventions in young adult populations.
Exercise addiction, muscularity-oriented eating and beliefs about sports nutrition supplements in students who regularly exercise
Authors: Arslan Kabasakal Sema
Published: December 2024

Background and Study Aim. Regular exercise has a positive effect on physical, psychological, and social health. However, excessive participation in exercise and the need for compulsive exercise can lead to exercise addiction. This addiction may result in several issues, including injuries, unhealthy eating behaviors, and negative attitudes. To prevent these potential problems, it is important to identify the extent of exercise addiction among individuals who exercise regularly. In this regard the study aims to examine the potential relationships between exercise addiction, muscularity-oriented eating and belief levels in sports nutritional supplements among students.
Material and Methods. The study included 377 participants with a mean age of 24.46 ± 6.18. All participants had been exercising regularly for at least one year, with a frequency of two days per week. Data were collected using a demographic form, the Exercise Addiction Scale, the Muscularity-Oriented Eating Test (MOET), and the Sport Nutritional Supplements Belief Scale.
Results. The findings suggest that 84.6% of the participants may be classified as dependent on exercise addiction. There is a low-level but significant positive relationship between exercise addiction and muscularity-oriented eating levels (r = 0.189, p < 0.001). A similar relationship exists between exercise addiction and beliefs in sports nutrition supplements (r = 0.179, p < 0.001). Furthermore, a moderately significant positive relationship was found between muscularity-oriented eating and beliefs in sports nutrition supplements (r = 0.361, p < 0.001). Analyses based on exercise addiction levels revealed notable differences. The dependent group showed higher levels of muscularity-oriented eating compared to the risk group. They also exhibited stronger beliefs in sports nutrition supplements.
Conclusions. Regular exercise among students leads to a higher likelihood of developing exercise addiction. Exercise addiction is associated with muscularity-oriented eating behaviors and strong beliefs in the efficacy of sports nutritional supplements. These behavioral patterns increase the risk of potential health issues related to excessive exercise and unhealthy dietary practices. Providing education on the effects of exercise, proper nutrition, and the responsible use of nutritional supplements is essential to mitigate these risks and promote healthier habits.
Dribbling emotions and anxiety in women’s football: a scoping review
Authors: Trandafirescu Elena-Andreea , Potop Vladimir , Mihai Ilie , Fleancu Julien Leonard , Cojanu Florin , Trandafirescu Gabriel
Published: December 2024

Background and Study Aim. Fear of failure, choking under pressure, financial disparities in income, and concerns related to body image and social pressure may intensify on-field challenges. These factors make the competitive environment particularly demanding for female soccer players. The aim of the current review is to map the available evidence on anxiety in women's football over the past decade and to identify interventions designed to manage anxiety among female soccer players.
Material and Methods. A scoping review was conducted following the PRISMA-ScR guidelines. An extensive search was carried out across four major databases for publications dated between 2014 and 2024. Two independent reviewers screened titles and abstracts, followed by full-text screening and data extraction. Any disagreements were resolved by a third researcher. The findings were tabulated and synthesized in a narrative format. The study was pre-registered on the Open Science Framework.
Results. The search yielded 2885 unique records. A total of 21 texts were reviewed in full, and the final sample included 14 studies. Some of the records included mentioned modifications to psychosocial interventions, such as Virtual Reality (VR) relaxation sessions, pre-exercise sporting massage, and psychological training programs (including psycho-neuromuscular theory and visualization techniques). These interventions led to a reduction in anxiety, though their effectiveness varied significantly across different approaches. Our results suggest that research on women's football may disproportionately focus on psychological interventions for managing anxiety. This highlights the need for broader investigations into other factors that influence athletes' performance and well-being.
Conclusions. This scoping review helps clarify the current landscape of anxiety research in women's soccer. It highlights both promising interventions and gaps in the research over the past decade. Although the body of evidence on anxiety interventions is small, it suggests that psychological interventions may be effective in reducing anxiety among female soccer players.

Authors: Gok Umut , Gok Yagmur , Kurt Emine Ilkcan , Canikli Abdullah
Published: December 2024

Background and Study Aim. Effective warm-up strategies are crucial for optimizing performance in team sports. However, identifying the most effective protocols requires consideration of the specific conditions and age of young athletes. The purpose of this study is to examine the acute effects of three different warm-up programs on specific test performance responses in young soccer players.
Material and Methods. Twenty-three amateur soccer players (age = 15.13 ± 0.81 years) participated in the study. The athletes performed a dynamic warm-up along with two different neuromuscular warm-up programs: the FIFA 11+ and the Injury Prevention and Performance Enhancement Program. Performance responses in sprint, jump, and agility tests were measured. Data normality was assessed with the Shapiro-Wilk test. The effects of the warm-up protocols were analyzed using one-way repeated measures ANOVA, with significance set at p < 0.05.
Results. The research findings revealed a statistically significant difference in the 10m sprint, 20m sprint, vertical jump, and zig-zag agility tests, both with and without the ball, when using the FIFA 11+ warm-up program (p < 0.05). The study demonstrated that the FIFA 11+ warm-up program improved performance responses more effectively than the other warm-up programs. This warm-up protocol enhances neuromuscular control by increasing the activation of the core, hip, and leg muscles.
Conclusions. The study demonstrates that the FIFA 11+ warm-up program significantly enhances performance in specific tests, such as sprinting, jumping, and agility. Coaches are encouraged to implement the FIFA 11+ protocol in both training sessions and pre-match routines to optimize athletic performance in young soccer players.

Published: December 2024

Background and Study Aim. High-intensity interval training (HIIT) has become a popular exercise choice for people who have limited time but aim to maximize their workout results. This study aims to compare the impacts of high-intensity running interval training (HIRIT) and high-intensity progressive resistance training (HIPRT) on oxidative stress biomarkers and antioxidant levels in healthy young males.
Material and Methods. The study included 30 healthy male adolescents aged 20–23 years who participated in HIRIT and HIPRT interventions over a four-week period. Data were collected by measuring levels of Malondialdehyde (MDA) and Superoxide Dismutase (SOD) as biomarkers of oxidative stress and antioxidants. These measurements were obtained before and after the intervention using Colorimetric Assay Kits. Data analysis was performed using paired sample t-tests and independent sample t-tests with a significance level set at 5%.
Results. The results showed a significant decrease in MDA levels in both high-intensity training interventions. However, SOD levels increased significantly only in the high-intensity running interval training group (p ≤ 0.05). Additionally, comparisons between groups revealed a reduction in MDA levels and an increase in SOD levels (p ≤ 0.05).
Conclusions. These findings suggest that both high-intensity running interval training and high-intensity progressive resistance training, conducted over a four-week period, are effective in reducing oxidative stress. Additionally, both types of training increase antioxidant levels in healthy young men. However, high-intensity running interval training proved to be more effective in reducing MDA levels and increasing SOD levels.

The political and ideological causes of the Anglo-Dutch wars
Authors: Borus György
Published: December 2024

This paper seeks to explore and explain the causes of the first three Anglo-Dutch wars. It argues that the political and ideological causes of these wars were at least as important as the economic ones, and that they cannot be fully understood without highlighting the political and ideological differences between the regimes of England and the United Provinces at the outbreak of the conflicts. It discusses in detail the causes of the first two Anglo-Dutch wars, which are more controversial than those of the third.

In a competitive business environment, companies must carefully evaluate a range of complex factors to select suppliers that align with operational requirements and market demands. This study employs the Analytic Network Process (ANP) to identify and prioritize critical criteria for supplier selection, including halal certification, quality, sustainability, cost, delivery, flexibility, responsiveness, and technical capabilities. Data were collected through semi-structured interviews with supply chain managers and questionnaire-based surveys, integrating qualitative and quantitative insights. The ANP model was used to analyze the interdependence between these criteria, revealing that quality ranks highest (0.331), followed by halal certification (0.231) and cost (0.157). These findings highlight the priority given to maintaining high product quality and strict adherence to halal standards over short-term cost considerations. Supporting factors such as delivery, flexibility, responsiveness, technical capabilities, and sustainability were also evaluated for their roles in maintaining an efficient supply chain and meeting international logistics requirements. The structured ANP framework provides practical insights for halal instant food manufacturers, enabling them to optimize supply chain management and align with regulatory standards, market demands, and sustainability objectives. This approach enhances export capabilities and strengthens the competitive position of halal food producers in the global market

+This research examines the integration of local wisdom-based green construction practices and their influence on sustainable performance through implementation strategies in the Indonesian construction industry. It focuses on ten construction projects in Bali. The main problem faced is the lack of understanding of the effectiveness of local wisdom-based green construction practices in improving sustainable performance in developing countries. Using the Partial Least Squares Structural Equation Modeling (PLS-SEM) method, data was collected from 200 engineers involved in green construction projects. Results show that local wisdom-based green construction practices significantly influence sustainable performance, both directly (path coefficient 0.290) and indirectly through the mediation of implementation strategies (indirect effect 0.575). The research model shows high explanatory power with R-squared values of 0.802 for Implementation Strategy and 0.831 for Sustainable Performance. These findings indicate that integrating local wisdom in green construction practices when mediated by an effective implementation strategy, can significantly improve the sustainable performance of construction projects. Sustainable waste management was identified as the dominant indicator (loading factor 0.936) of local wisdom-based green construction. In contrast, alignment with government policies and regulations (loading factor 0.925) became critical in the implementation strategy. The results of this study can be applied by project developers, construction managers, and policymakers in designing more effective implementation strategies for integrating local wisdom into green construction practices, considering customizations based on variations in cultural and geographical contexts

The object of this study is to evaluate the potential of quail eggshells as a raw material for producing porous and electrically conductive activated carbon by focusing on the effect of carbonization temperature. The main problem solved is the lack of utilization of quail eggshell waste, despite its unique microporous structure and rich mineral and organic content. This underutilized waste, often discarded, represents an opportunity to align sustainable practices with the development of advanced materials for adsorbent and energy applications.
The results showed that the activated carbon produced at a carbonization temperature of 400 °C had superior properties compared to higher temperatures (500 °C and 600 °C), with the highest surface area and electrical conductivity. FTIR characterization identified important functional groups such as O-H, C=O, C=C, and CaO, which support the formation of the carbon framework and contribute to the stability and functionality of the material. XRD patterns confirmed the hexagonal carbon structure, a desirable feature for maintaining structural integrity in demanding applications.  SEM revealed irregular morphologies, while BET analysis showed a combination of micropores and mesopores. Under optimal carbonization conditions, activated carbon produced at 400 °C offers a combination of structural and conductive properties. It achieved a specific surface area of 296.875 m2/g, indicating excellent porosity for adsorption applications. Additionally, the material exhibited an electrical conductivity of 1.62×10-2 S/cm, which is suitable for energy storage devices such as supercapacitors and batteries. The decrease in these properties at higher carbonization temperatures highlights the importance of optimizing synthesis parameters to achieve desired outcomes.
 These structural and conductive properties make the material suitable for advanced applications in environmental remediation, renewable energy, and waste management. By converting quail eggshells into high-value activated carbon, the study demonstrates a feasible approach to reducing waste while contributing to eco-friendly material development. This study proves that quail eggshells can be effectively utilized, adding value to organic waste while increasing its economic viability

loads in the structure of a container with a floor made of sandwich panels under operational modes.
To ensure the strength of the container, as well as the safety of the cargo transported in it, it is proposed to design a floor based on sandwich panels. It is assumed that each of these panels is made of two metal sheets in a layer between which an energy-absorbing material is placed. Given the presence of energy-absorbing material in the structure of the sandwich panel, the vertical dynamic loads acting on the cargo container during its transportation will be reduced.
To substantiate the proposed solution, mathematical modeling of the vertical load on the container during its transportation by a flat wagon was carried out. It is found that the accelerations acting on the container of the improved design are 5.7 % lower than those acting on the container of standard design.
The calculation of the strength of the container was carried out under operational schemes of its loads. It has been established that the strength of the container is ensured.
A special feature of the results is that the reduction of the load on the container is achieved not by strengthening its structure but by introducing flexible connections into it.
The field of practical application of the results is railroad transport. The conditions for the practical use of the findings are the use of energy-absorbing material in the structure of sandwich panels that form the floor of the container.
The results of the research will contribute to improving the strength of containers under operating conditions, the safety of the cargo transported in them, as well as increasing the efficiency of the functioning of container transportation
