Challenges and responses in the geo-engineering education

P. Scharle

Publication Name: Proceedings of the 1st International Conference on Education and Training in Geo Engineering Sciences Soil Mechanics Geotechnical Engineering Engineering Geology and Rock Mechanics

Publication Date: 2008-01-01

Volume: Unknown

Issue: Unknown

Page Range: 443-446

Description:

Structural engineers assess the geotechnical problems as difficult to model, complicated to calculate and full of crude approximations. In return, clear constraints hindering the practical use of advanced mechanical theories and computational software decrease the interest of geotechnicians in studying and applying them. In designing complex structures both sides restrict themselves in many cases to the exchange or prescription of some data given on interfaces. The paper presents an overviewon differences either loosing their importance or remaining significant between these structural and geotechnical perspectives. Educational consequences related to the Bologna-process are discussed. Role of case studies and understanding of the observational method's importance are stressed. The paper concludes that geotechnical education should and could correspond to the challenges with more conscious and better structured curricula. © 2008 Taylor & Francis Group, London.

Work addiction among managers: a battery of demands and resources approach

Tibor Dory Ádám Páthy Angéla Somogyi Lili Anna Hujber Attila Szabo

Publication Name: Cogent Psychology

Publication Date: 2025-07-30

Volume: 12

Issue: 1

Page Range: Unknown

Description:

Work addiction negatively impacts health and well-being, yet little research has focused on managers, whose excessive work involvement can affect entire organizations. This study examined psychological predictors of work addiction and differences between work-addicted and non-addicted managers. Two hundred managers were assessed via the Qualtrics research platform, with work addiction classified using the Bergen Work Addiction Scale. We analyzed 11 psychological measures: exhaustion, disengagement, stress, obsessive and harmonious passion, well-being, work-family and family-work conflict, perceived physical and mental health, and sleep quality. Logistic regression significantly predicted group membership (p < 0.001), explaining 39.7%–57.0% of the variance and correctly classifying 84.5% of cases. Multivariate analysis of variance showed significant differences across all measures except one between the two groups. Work-addicted managers also showed poorer physical and mental health, and lower sleep quality. The prevalence of work addiction was high (29%) in this sample, highlighting the need for targeted interventions. As the first study to identify multiple psychological predictors of work addiction in managers, the findings may be valuable for organizations concerned with occupational mental health. However, cross-national replication is necessary before generalizing results. Recognizing the psychological toll of work addiction can help policymakers develop effective, sustainable interventions.

Understanding the Role of PBAT Content and Raster Orientation on the Mechanical Performance of Material Extrusion 3D-Printed PLA/PBAT Objects

László Lendvai András Lajos Nagy Sándor K. Jakab

Publication Name: Polymers

Publication Date: 2026-02-01

Volume: 18

Issue: 3

Page Range: Unknown

Description:

Poly(lactic acid) (PLA) is the most widely used feedstock in material extrusion (MEX) 3D printing. In this study, PLA was combined with 0–40 wt.% of poly(butylene adipate-co-terephtalate) (PBAT) to improve its ductility. The resulting blends were processed into filaments suitable for MEX 3D printing and used to fabricate specimens for mechanical characterization using three distinct raster angles (RAs; 0°, ±45°, and 90°) to statistically evaluate the individual and joint effects of blend composition and raster orientation. Melt flow index (MFI) measurements showed that increasing PBAT content reduced the MFI from 40.4 g/10 min to 34.4 g/10 min, which led to weaker bonding between printed beads, as shown in scanning electron microscopic images. Tensile strength, modulus, and impact strength were evaluated using tensile and Charpy tests. Statistical analysis showed that RA, PBAT concentration, and their interaction all significantly influenced (p < 0.05) mechanical performance. Both strength and modulus decreased as PBAT content and RA increased, with the highest values of 50 MPa and 2.78 GPa observed for neat PLA 3D-printed at 0° RA, and the lowest values of 15 MPa and 1.05 GPa for 40 wt.% PBAT at 90° RA. In contrast, incorporating PBAT improved impact strength, showing its toughening effect. Meanwhile, no clear trend between impact resistance and RA was observed. The highest impact strength (52.7 kJ/m2) was found at 40 wt.% PBAT content and ±45° RA.

Female physicians' and nurses' self-rated general and psychosocial health status and health behaviour in Hungary

Kovácsné Tóth Ágnes Feith Helga Judit Balázs Péter

Publication Name: New Medicine

Publication Date: 2007-07-01

Volume: 11

Issue: 3

Page Range: 55-58

Description:

Aim. This study analyses the self-rated general and psychosocial health of female physicians and nurses in Hungary related to healthy lifestyle habits and individual behavioural patterns. Material and method. cross-sectional data were taken by a questionnaire survey among Hungarian female health care staff members (N=409) selected representatively in 2005 (responding rate 45.5%). Results. Six out of ten staff members mentioned at least one health problem. Strongly related to self-rated health (SRH) were role conflicts (p<0.001), pessimistic future expectations (p<0.001), perceived difficulties in maintaining the actual partnership (p=0.001), and satisfaction with one's life and career (p<0.001). About 40% said that they did some sports once a week or even more frequently. Smokers represented 24.4%. Conclusion. The results obtained suggest that health is not a highly appreciated value among female staff members in Hungarian health care. Moreover, their health-related behaviour is at a substandard level. Improving this situation should be a priority aim of any intervention. ©Borgis.

Central and Eastern European Examples of University. Institutional Aspects of Understanding Sustainability

Marta Konczosne Szombathelyi István András Gáborné Nagy

Publication Name: Chemical Engineering Transactions

Publication Date: 2023-01-01

Volume: 107

Issue: Unknown

Page Range: 187-192

Description:

The scope of this paper is the interpretation of sustainability through the university as a traditionally recognized, value-based institution of knowledge, based on the example of Central and Eastern Europe, Hungary. Its aim is to interpret sustainability from different aspects, using the example of Central and Eastern Europe, including Hungary. For this purpose, the paper reviews the development policy directions of the past period and institutional realizations through public databases. The results of the research show that there are different dynamics and focus in terms of resources and development implementations. From the point of view of sustainability, it represents that the use of resources with different dynamics and focus is a challenge for the institutions.

The Development of Mood Repair Response Repertories: I. Age-Related Changes Among 7- to 14-Year-Old Depressed and Control Children and Adolescents

Publication Name: Journal of Clinical Child and Adolescent Psychology

Page Range: 143-152

Description:

The purpose of this study was to test developmentally informed hypotheses about regulatory responses to sadness that attenuate versus exacerbate it (adaptive versus maladaptive mood repair responses, respectively) across late childhood, early adolescence, and mid-adolescence. In a multi-site study in Hungary, clinic-based, 7- to 14-year-olds with Diagnostic and Statistical Manual of Mental Disorders’ (4th ed., text rev.) depressive disorders (N = 697; 55% male) and age/sex matched (at 1:2) nondepressed, school-based controls (N = 1,394) reported on their usual responses to sadness/dysphoria; parental reports were obtained separately. Adaptive and maladaptive response repertoire scores were compared across ages within and across subject groups, and by informant, controlling for confounds. Contrary to Hypothesis 1, older (vs. younger) youths in both groups reported fewer adaptive regulatory responses. Maladaptive response repertoires were unrelated to age among controls but significantly increased with age among depressed youths, particularly the girls. Partially supporting Hypothesis 2, subject groups differed in age-related trajectories of mood repair repertories, but not as expected (e.g., younger depressed children reported larger adaptive response repertoires than did controls). Parental reports revealed no developmental changes in offspring’s mood repair repertories. Parent-offspring reports were most discordant for younger (vs. older) offspring, tended to converge around age 11, and were consistently and significantly larger in the depressed sample. Self-reported adaptive mood repair repertories appear to have been laid down by late childhood and then undergo “trimming” across ages 7–14 years. The extensive maladaptive mood repair response repertoires of depressed youths, which increased with age, distinguish them primarily from controls. Therefore, reducing maladaptive regulatory responses to sadness should be a priority when treating depressed youths.

Factors and Health Effects of Excessive Smartphone Use: The Impact of Bedtime Delay on Young Adults in Developing Countries

Abdullah Al Masud Mohammad Fakhrul Islam Rashedul Hasan Shanto Aireen Ferdous Rabeya Sultana Lata Chowdhury Mehtaj Jabeen Medha

Publication Name: International Journal of Community Well Being

Publication Date: 2025-07-01

Volume: 8

Issue: 2

Page Range: 383-416

Description:

This study investigates the factors that lead to smartphone addiction in young adults as well as the negative health effects of this addiction. This study used confirmatory factor analysis (CFA) and structural equation modeling (SEM) to analyze the data from 430 online questionnaires of young adults aged between 15 and 55. The findings show that the association between smartphone addiction and health hazards is significantly mediated by bedtime procrastination, which links excessive usage of the device to negative mental and physical effects. The findings show that impulsivity, depression, gaming addiction, cyber-loafing, and other behavioral and psychological characteristics all play a major role in smartphone addiction, which has an adverse impact on both mental and physical health. Among the participants, 80% were single and 61.1% were female; these groups had greater rates of addiction and related health issues. The results have significant implications for psychiatrists, psychologists, parents, and anyone concerned about smartphone addiction and its associated health risks. The study highlights the crucial role of bedtime procrastination as a mediator in this context. This material will be particularly beneficial for therapists specializing in treating smartphone addiction in both children and adults.
